Description

  The present invention relates to a steam ejector used for wrinkling a textile product such as clothing.

  Conventionally, in this type of steam ejector, water stored in a water tank is supplied to a vaporization chamber by a pump device, and the vaporized steam is ejected to clothing or the like to stretch wrinkles. By using a pump device for water supply to the vaporization chamber, restrictions due to gravity in the water supply direction can be eliminated, and steam can be ejected with the steam ejector directed in any direction. The wrinkle-stretching operation of clothing and the like by a steam ejector is generally performed in a state where clothing or the like is hung on a hanger. In order to enhance the wrinkle-stretching effect, there has been considered a steam ejector in which a brush is provided so that brushing can be performed while supplying steam to clothes hung on a hanger (see, for example, Patent Document 1).

  As shown in FIG. 10, the conventional steam ejector described in Patent Document 1 has one end of the bimetal 53 fixed to the upper surface side of the vaporization chamber 52 heated by the embedded heater 51, and the other end of the bimetal 53. Is linked to a thermally responsive on-off valve 55 provided in the water supply passage 54. When the vaporizing chamber 52 is heated to a temperature at which water can be vaporized, the bimetal 53 senses the heat of the vaporizing chamber 52 and performs a reverse operation to open the thermally responsive on-off valve 55. The pump device 56 is driven by manual operation of the operation unit 58 provided on the handle 57, and the water stored in the tank 59 is transferred to the vaporization chamber 52 through the heat responsive on-off valve 55 provided in the water supply path 54 by the pump device 56. Water is sent.

  The vaporizing chamber 52 is adjusted to a water vaporizable temperature set in advance by the thermostat 60, and is fixed to the lower surface side of the vaporizing chamber 52. Further, a thermal fuse (overheat prevention device) 61 is connected in series with the thermostat 60, and is fixed to the lower surface side of the vaporizing chamber 52 in the vicinity of the thermostat 60. On the lower surface side of the vaporizing chamber 52, a steam blowout plate 62 made of heat-resistant resin is provided so as to cover the vaporizing chamber 52 and the like from below, and the steam generated in the vaporizing chamber 52 is jetted from the steam hole 63. A brush 64 is provided on the peripheral edge of the steam ejection board 62, and the steam is supplied while brushing the clothes hung on the hanger, so that tension is applied to the clothes and the like so as to enhance the wrinkle stretching effect.

  In addition, it has been considered to provide a hooked surface portion having a large frictional resistance characteristic on the outer surface side of the steam jetting portion that is brought into contact with clothing or the like, thereby increasing the tension acting on the clothing or the like and enhancing the wrinkle stretching effect. The hanging surface portion is configured by a porous body such as a continuous foam that permeates steam, or a fiber body having a three-dimensional mesh structure (for example, see Patent Document 2).

However, in the conventional configuration, it is necessary to hold the steam ejector with one hand and operate the pump device to eject the steam while performing the operation of adjusting the shape of the clothing with the other hand. There was a problem of poor usability. In addition, if the tension applied to clothing or the like is temporary, there is a problem that moisture due to steam remains in the clothing or the like and it is difficult to enhance the wrinkle stretching effect.

  Therefore, it is possible to remove moisture from the fibers stretched by steam by heating the clothes containing moisture due to steam at the same time as the ejection of the steam, and the clothes etc. at the base from which the steam is ejected. It has been confirmed that the wrinkle-stretching effect is enhanced by heating.

  However, as described above, the steam blower can be used to adjust the shape of the clothes, etc., with the other hand, so that the clothes hung on the hanger are stretched in the wrinkle-extending direction, for example, downward tension is applied. In order to move the steam ejector while ejecting steam toward the holding part, it is necessary to use it so as not to approach the other hand holding clothing etc., enhancing the wrinkle stretching effect The realization of improved usability at the same time was an issue.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a steam ejector that enhances the wrinkle stretching effect and is easy to use.

  In order to solve the conventional problem, a steam ejector of the present invention includes a vaporization chamber for generating steam, a heater for heating the vaporization chamber, a water tank for storing water supplied to the vaporization chamber, A pump device that supplies water in the water tank to the vaporization chamber; a base that heats clothing; and a housing that covers an upper surface side of the base; Projecting downward, the outer peripheral edge of the base is configured to be located inward from the lower peripheral edge of the housing.

  This makes it possible for the steam sprayer to wet the clothes, etc. by the steam spray, and at the same time to remove moisture by heating with the base. It can be made more difficult to return, and the wrinkle stretching effect can be enhanced. In addition, when the steam blower is moved relative to the clothes, etc., the heated base does not come into contact with the other hand holding the clothes, etc. Improvement and usability issues can be solved simultaneously.

  The steam ejector of the present invention can improve the crease-stretching effect of clothes and the like and improve the usability.

The base 4 is provided with a plurality of steam holes 9, and the steam generated in the vaporizing chamber 1 is ejected from the steam holes 9 through the meandering steam passage 8 formed by the partition plate 7.

  The base 4 is formed in an approximately oval shape that is elongated in the front-rear direction, and the front end part 4a and the rear end part 4b are formed in a slightly rounded pointed shape, and the lower surface of the base 4 is extended in the front-rear direction so as to expand outward. It is formed in an arcuate curved shape in both the left and right directions. Further, the outer peripheral edge 4c of the base 4 is rounded so as not to have an edge shape. A plurality of steam holes 9 (five in the present embodiment) are provided in the longitudinal direction in the raised portion formed in the curved shape of the base 4. That is, when the user blows out the steam, the base 4 comes into contact with the clothing and the like so that the clothing and the like can be moistened and heated at the same time.

  A heat insulator 10 is provided above the base 4, and the heat insulator 10 is attached to the base 4 so as to cover the base 4 and the vaporized body 3 from above. A resin casing 11 provided above the base 4 is formed so as to surround the heat insulator 10 from the outside, and a grip portion 12 is provided on the upper portion of the casing 11. The grip portion 12 is formed in substantially the same length in the same direction above the elongated base 4. Thereby, when the user holds the grip portion 12, the casing 11 can be held with a good weight balance.

  The base 4 is formed so as to protrude downward by a predetermined amount D from the lower peripheral edge 11 a of the housing 11. Further, the outer peripheral edge portion 4 c of the base 4 is formed by retreating by a predetermined amount W inward from the outer surface of the lower end peripheral edge portion 11 a of the housing 11. A heat insulating material 13 having heat resistance is provided between the outer peripheral edge 4 c of the base 4 and the heat insulating body 10. In addition, a concave groove 10 a is provided on the outer peripheral surface of the heat insulator 10, and a heat insulating space is formed between the inner surface of the housing 11.

  The water supplied to the vaporization chamber 1 is stored in the water tank 14. The water tank 14 is disposed on the upper surface of the heat insulator 10 above the vaporization chamber 1. A water injection part 14 a is provided at the upper front of the water tank 14, and is configured to be opened and closed by a lid 15 provided in accordance with the shape of the housing 11. The water tank 14 is configured so that the amount of water in the water tank 14 can be visually recognized through the transparent display window 14b.

  The pump device that supplies the water in the water tank 14 to the vaporization chamber 1 is constituted by an electric pump 16. The electric pump 16 is disposed adjacent to the rear of the water tank 14. The type of the electric pump 16 is not particularly limited. For example, the electric pump 16 is configured by an electromagnetic pump. In the electromagnetic pump, a plunger mechanism is provided inside an electromagnetic coil provided on the outer periphery, and the plunger mechanism is reciprocated by the electromagnetic coil. The electric pump 16 is connected to a water suction pipe 17 that sucks water in the water tank 14 and a water feed pipe 18 that discharges the sucked water to the vaporizing chamber 1. By the reciprocating operation of the plunger mechanism, water in the water tank 14 is sucked through the water suction pipe 17, and this water is discharged to the vaporization chamber 1 through the water supply pipe 18.

  Inside the housing 11, a vaporizer 3 that forms the vaporization chamber 1, a water tank 14, an electric pump 16, and the like are provided. The grip unit 12 is provided with a power switch 19 for energizing the heater 2 and the control unit 20, a control unit 20 for controlling the driving of the electric pump 16, and a pump switch 21 for operating the driving of the electric pump 16. .

With these configurations, the pump switch 21 can be easily turned on / off while the user performs an operation of moving the housing 11 with respect to clothing or the like.

  FIG. 5 is a circuit diagram of the steam ejector according to the first embodiment of the present invention, FIG. 6 is a block diagram of the steam ejector, and FIG. 7 is a time chart showing the operation of the steam ejector. 5 to 7, the heater 2 and the control unit 20 are energized when the power switch 19 is turned on. The control unit 20 includes a timer 22 that starts timing when the power switch 19 is turned on, and includes a microprocessor, an IC timer, and the like incorporated in a control circuit (not shown). Then, the control unit 20 enables the electric pump 16 to be driven after a predetermined time T1 (for example, 40 seconds) after the timer 22 starts measuring time. That is, the timer 22 starts timing simultaneously with the start of energization of the heater 2, and the predetermined time T1 is set to a time during which the vaporizing chamber 1 is heated to a temperature t1 (for example, 150 ° C.) at which water can be vaporized.

  Further, after the power switch 19 is turned on, the control unit 20 delays the driving of the electric pump 16 until a predetermined time T1 when the vaporizing chamber 1 is heated to a temperature t1 at which water can be vaporized elapses. Even when the pump switch 21 is operated before T1 elapses, the electric pump 16 can be driven after the predetermined time T1 elapses.

  The control unit 20 sets the amount of water supplied to the vaporization chamber 1 by the electric pump 16 to be equal to or less than the vaporization capability of the vaporization chamber 1 and the electric pump so that the amount of water supply to the vaporization chamber 1 is equal to or less than the vaporization capability of the vaporization chamber 1 16 is configured to be driven. The vaporization ability is a state in which the water supplied to the vaporization chamber 1 can be instantaneously vaporized, and the supplied water is vaporized and ejected from the steam hole 9. The vaporization capacity is determined by the temperature of the vaporization chamber 1, the surface area and the amount of heat that come into contact with the supplied water, and the vaporization capacity can be set so as not to exceed the vaporization capacity.

  The controller 20 intermittently drives the electric pump 16 so that the set amount of water is supplied to the vaporization chamber 1. For example, by applying a part of the frequency in the voltage waveform to the electric pump 16 at a predetermined interval, the electric pump 16 can be driven intermittently at an arbitrary interval, and can be implemented by a general drive circuit.

  The steam ejector of the present embodiment is configured so that it can be placed on the stand 23 when not in use and at rest during use. The stand 23 includes a support portion 24 that supports the lower peripheral edge 11a of the housing 11 from below when the steam ejector is placed with the base 4 facing downward. The support portions 24 are arranged in an annular shape so as to face the lower end peripheral portion 11a of the housing 11, and are formed at a plurality of intervals (six locations in the present embodiment). In addition, the support part 24 may be continuously formed along the lower end peripheral part 11a of the housing 11. Further, the recess 23a of the stand 23 is recessed downward along the lower surface of the base 4 so that a space is formed between the lower surface of the base 4 and the recess 23a when the housing 11 is placed on the stand 23. It is formed to be recessed.

  In addition, the stand 23 is provided with a wall 25 that surrounds the base 4 from the outside, and an upper end portion 25 a of the wall 25 is positioned above the lower end peripheral edge portion 11 a of the housing 11. The support portion 24 is provided with a restriction portion 24a between the support portion 24 and the wall 25, and the lower end peripheral edge portion 11a of the housing 11 is placed at a predetermined position of the support portion 24 by the restriction portion 24a.

  About the steam ejector comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The user puts water into the water tank 14, places the steam blower on the stand 23, turns on the power switch 19, and energizes the heater 2. When the thermostat 5 senses the temperature of the vaporized body 3 and the vaporization chamber 1 is heated by the heater 2, the thermostat 5 is turned off at a second predetermined temperature t2 (for example, 170 ° C.), and the first predetermined temperature t1 (for example, for example) The ON operation is repeated at 150 ° C., and the vaporizing chamber 1 is maintained at a temperature at which water can be vaporized while not overheating. At this time, the base 4 is also heated simultaneously with the vaporizing chamber 1 by the heater 2, and the outer surface temperature of the base 4 is adjusted to be kept, for example, about 20 ° C. lower than the vaporized body 3.

  At the start of use, when the predetermined time T1 (for example, 40 seconds) has elapsed after the timer 22 that starts timing by turning on the power switch 19 at the start of use, the controller 20 The electric pump 16 is driven by an ON operation by pressing the water to feed water in the water tank 14 to the vaporizing chamber 1. Further, the controller 20 turns on the pump switch 21 before the predetermined time T1 has elapsed since the power switch 19 was turned on, that is, before the vaporization chamber 1 was heated to a temperature at which water can be vaporized. In this case, the driving of the electric pump 16 is delayed, and the electric pump 16 can be driven after a predetermined time T1 has elapsed.

  Thereby, even when the pump switch 21 is operated when the vaporizing chamber 1 is not heated to a temperature capable of vaporizing water at the start of use, the electric pump 16 is not driven, and the vaporizing chamber 1 is supplied to the vaporizing chamber 1. Water supply can be prevented. In this case, the ON operation of the pump switch 21 is reset, and the electric pump 16 is driven again by the ON operation of the pump switch 21 after a predetermined time T1, so that the steam is not inadvertently ejected. Further, during use, since the amount of water supplied to the vaporizing chamber 1 by the electric pump 16 is set to be equal to or less than the vaporizing capacity of the vaporizing chamber 1, the water is not excessively supplied to the vaporizing chamber 1, and the steam ejector Can stably eject the steam, and can prevent the operation from being interrupted due to a decrease in the temperature of the vaporizing chamber 1.

  FIG. 8 is a usage state diagram of the steam ejector according to the first embodiment of the present invention, and shows an example of usage. The wrinkle-stretching operation of clothing and the like by the steam ejector by the user is generally performed in a state where the clothing or the like is hung on a hanger. In this case, as shown in FIG. 8, the user holds the grip portion 12 with one hand and holds the steam ejector in the direction in which the steam is ejected, and operates the electric pump 16 to eject the steam. The base 4 is placed along the clothing A while performing the operation. At the same time, the user holds the garment A so that the tension P acts on the clothes A hung on the hanger H in a wrinkle-stretching direction, for example, downward, in order to shape the garment A with the other hand.

  When the user moves the steam ejector along the clothing A while ejecting steam, the base 4 protrudes downward (in the direction of the clothing A in FIG. 8) from the lower peripheral edge 11 a of the housing 11. Therefore, the garment A can be moistened with steam, and at the same time, the garment A can be heated to remove moisture and be dried. Thereby, the state which extended the fiber with steam can be made harder to return from the effect | action of only a steam, and a wrinkle extension effect can be heightened.

  The rear surface of the water tank 14 is inclined so that the left side of the water tank 14 is lowered when the longitudinal direction of the base 4 is held substantially vertically with the front end portion 4a of the base 4 facing upward. This is because when the user grips the grip portion 12 with the right hand and holds the base 4 as described above, the casing 11 tends to tilt to the left when the steam ejector is moved downward, and the left side of the water tank 14 is By lower than the right side. Therefore, the water supply portion of the water suction pipe 17 that sucks in the water in the water tank 14 is provided so as to be located at the bottom left side of the rear surface where the water in the water tank 14 easily collects, thereby reducing the water in the water tank 14. Even in such a case, the electric pump 16 can easily absorb water.

  Further, since the outer peripheral edge portion 4c of the base 4 is configured to be located inward (upward in FIG. 8) from the lower end peripheral edge portion 11a of the housing 11, the base 4 holds the clothing A on the other side. It can be used without touching the hand. As a result, the wrinkle-stretching effect of the garment A is enhanced by the heat of the steam and the base 4, and the user can use it safely, improving usability.

  The base 4 for heating the clothing or the like is formed in an arcuate curved shape so as to bulge outward, and the central portion 4d of the base 4 is formed so as to rise. Thereby, when the user moves the steam ejector in contact with clothes or the like, the outer peripheral edge 4c of the base 4 can be made difficult to contact with clothes or the like due to the curved shape of the base 4 and has an edge. Partial overheating of clothes and the like generated by the base 4 can be prevented.

  The base 4 is formed in an elongated oval shape, and the front end portion 4a and the rear end portion 4b of the base 4 are formed in a substantially pointed shape. Accordingly, the steam generator can easily move in both the forward and backward directions when the base 4 is moved in the longitudinal direction, and can prevent clothing and the like from being folded and overlapped. Generation of wrinkles can be prevented.

  Further, when the steam generator is placed on the stand 23 during a resting period in use, the support portion 24 supports the lower peripheral edge 11 a of the housing 11, and between the lower surface of the base 4 and the recess 23 a of the stand 23. A space is formed. Thereby, it is possible to prevent the stand 23 from being overheated by the heat of the base 4. Further, the occurrence of scratches due to the base 4 coming into contact with the stand 23 is suppressed, the surface of the base 4 is kept in a smooth state, and when the user contacts the base 4 with clothing or the like and heats it, the base 4 Can be moved smoothly without being caught on clothing or the like.

  The stand 23 is provided with a wall 25 that surrounds the outer peripheral edge 4c of the base 4 from the outside, and the upper end 25a of the wall 25 is positioned above the lower peripheral edge 11a of the housing 11. Is. Thereby, when the steam ejector is placed on the stand 23 during a rest in use, the stand 23 can safely protect the heated base 4.

In addition, the pump device that supplies the water in the water tank 14 to the vaporization chamber 1 is configured by the electric pump 16, and includes a control unit 20 that controls the driving of the electric pump 16, and the control unit 20 includes the vaporization chamber 1. The electric pump 16 can be driven when heated to a temperature at which water can be vaporized, and the amount of water supplied to the vaporization chamber 1 by the electric pump 16 is set to be equal to or less than the vaporization capacity of the vaporization chamber 1. Thereby, the steam ejector can reduce the burden on the hand for holding the steam ejector by the user and performing the operation of ejecting and stopping the steam, thereby improving the usability. In addition, a bimetal that senses the heat of the vaporization chamber 1 and operates the heat-responsive on-off valve, which has been indispensable for preventing water leakage due to excessive water supply to the vaporization chamber in use, is no longer necessary. Can be stably ejected. In addition, a thermostat for temperature adjustment that has been disposed on the lower surface of the vaporizing chamber 1 and a thermal fuse as an overheat prevention device can be disposed on the upper surface of the vaporizing chamber 1. As a result, the base 4 can be thermally coupled to the lower surface side of the vaporizing chamber 1 to be compactly configured.

  The electric pump 16 may be a centrifugal pump or the like as long as it is electrically driven and the amount of water supply can be set.

  Further, the water tank 14 may be configured to be detachable from the housing 11. In this case, the water tank 14 is detachably connected to the water absorption pipe 17 in accordance with the attaching / detaching operation.

  As described above, the steam ejector according to the present embodiment includes the vaporization chamber 1 for generating steam, the heater 2 for heating the vaporization chamber 1, the water tank 14 for storing water supplied to the vaporization chamber 1, and A pump device (electric pump 16) that supplies water in the water tank 14 to the vaporizing chamber 1, a base 4 that heats clothing, and a housing 11 that covers the upper surface side of the base 4 are provided. The outer peripheral edge portion 4c of the base 4 is configured to be located inward of the lower end peripheral edge portion 11a of the housing 11. As a result, the steam ejector can wet the clothes, etc. by the steam ejection, and at the same time, can be heated by the base to remove the moisture and dry it. It is possible to make it harder to return than the only action, and to enhance the wrinkle stretching effect. Furthermore, when the steam blower is moved relative to the clothing, etc., the heated base does not come into contact with the other hand holding the clothing, etc., and can be used safely, improving usability. be able to.

A feature of the steam ejector according to the second embodiment is that when the temperature detecting unit 26 that detects the temperature of the vaporizing chamber 1 detects that the vaporizing chamber 1 is heated to a temperature at which water can be vaporized, the electric pump 16 is turned on. It is possible to drive. Other configurations are the same as those of the first embodiment, the same reference numerals are given to the same configurations, and the detailed description of the first embodiment is used.

  The temperature detection unit 26 includes a thermistor or the like that detects the temperature of the vaporized body 3, and an output signal of the temperature detection unit 26 is input to the control unit 27. When the pump switch 21 is turned on during use, if the temperature detection unit 26 inputs that the vaporization chamber 1 is heated to the set temperature to the control unit 27, the electric pump 16 is driven and the vaporization chamber is driven. A set amount of water is sent to 1, and steam is ejected.

  When it is input to the control unit 27 that the vaporizing chamber 1 is not heated to the set temperature by the temperature detection unit 26, the electric pump 16 is not driven even when the pump switch 21 is turned on, and is in an inoperative state. Can be maintained. Thereby, since the control part 27 can prevent the water supply to the low temperature vaporization chamber 1, it can prevent that water leaks out from the steam hole 9, without vaporizing.

  As described above, the steam ejector according to the present invention enhances the effect of stretching wrinkles of clothes and the like and improves usability, so that it is useful as any form of steam ejector.
