Description

  The present invention relates to a gas dryer suitable for carrying.

General hair dryers are assumed to be used in homes where a commercial AC power supply (AC100-120VAC 200-240V) is supplied, or in hotels, hair salons, and beauty salons. Cannot be used at all. (Patent Document 1)
For this reason, portable dryers have been proposed. The biggest problem with portable dryers is that hot air with high air temperature and high air volume cannot be taken out. There is a correlation between the reason why the air temperature cannot be increased and the reason why the air volume cannot be increased.

  For example, even if the calorific value (gas burner combustion amount) is increased and the air temperature is increased, if the air flow is small, it is not suitable for drying hair, and conversely the battery voltage (increasing the number of batteries) is increased to increase the motor speed. Even if the air volume is increased and the air temperature is increased, it is not suitable for drying as the air temperature is low.

  That is, in the case of carrying, the weight cannot be increased and the size of the dryer body cannot be increased. As a result, the number of batteries cannot be increased spilloverly, the number of rotations of the fan cannot be increased, and the air volume is reduced.

  If a battery having a high battery voltage is used to increase the rotational speed of the fan, the battery capacity is reduced and the usage time is shortened. Furthermore, when the usage time is increased, the battery capacity may be increased, but the weight and size of the battery increase, which is not suitable for carrying.

  Similarly, it is possible to increase the heat generation amount (combustion amount) and increase the air temperature by increasing the gas consumption in the burner. However, since the combustion time is shortened, it is necessary to increase the internal capacity of the gas cylinder. is there. Increasing the gas cylinder content in this way is not suitable for carrying because the gas cylinder size increases.

For the above-described reasons, there is a so-called pistol type hair dryer in which a gas cylinder is stored using a hollow portion in a handle. (Patent Document 2)
JP-A-5-137612 JP-A-6-133816

  However, in the case of the above-described prior art, it is not necessary to separately provide a gas cylinder storage portion by storing the gas cylinder in the handle, but since the battery is also stored in the same handle, the thickness of the handle is small. There is a drawback that it becomes large and difficult to grasp. If the handle is made thinner, it will be easier to grip, but the gas cylinder will be smaller in size, the combustion amount (gas consumption) will be lower, the air temperature will be lower, the combustion time will be shorter, and at the same time the battery size will be smaller and the continuous use time will be shorter.

  In particular, detachably storing the gas cylinder in the handle means that the gas hose connecting the gas cylinder and the burner, the open / close valve provided in a part of the gas hose, the motor power switch, and the positional relationship with each functional part of the ignition device Must be fully considered.

  In detail, the overall vibration, impact, and mechanical movement of the gas cylinder that occur when the gas cylinder is attached / detached touches the opening / closing valve, causing the valve to open unexpectedly, or the gas hose to be crushed and damaged. This may cause a failure of the power switch or the ignition device.

  The present invention makes it possible to increase the size of the gas cylinder by storing the gas cylinder stored in the handle and the functional parts such as the device for opening / closing and igniting the gas and the power switch in a completely separated space. This prevents malfunction of functional parts.

  The present invention includes a cylindrical casing having a wind blowing portion on the front side and an intake portion on the rear side, a burner, an igniter, a fan and a motor disposed in the cylindrical casing, and a rotating circuit mounted on the cylindrical casing. A hollow cylinder length handle that is movably connected, and a partition plate provided in the handle divides at least an upper space portion and a lower space portion, and in the upper space portion, a gas flow path opening / closing means to the burner and the ignition Electric circuit opening and closing means for applying a high voltage to the container and cutting off the power to the motor, and the partition plate includes an extending portion extending to the upper space side and a cylindrical engaging portion extending to the lower space side A gas hose following the burner is connected to the extended portion, and a gas cylinder for supplying gas to the burner is detachably mounted in the lower space via the gas channel opening / closing means. And this gas cylinder It is intended for communicating the supply and hose to supply part of the gas cylinder when mounted into the lower space and connected to the engaging portion.

  The lower space portion opens at a lower portion opposite to the partition plate, and the gas cylinder is detachably inserted from the opening portion, and the gas cylinder is held by a holder provided on the inner wall of the handle.

  According to the present invention, the hollow cylindrical handle is divided into an upper space portion and a lower space portion, a gas flow path opening / closing means and an electric circuit opening / closing means are provided in the upper space portion, and a gas cylinder is detachable in the lower space portion. It is installed in the upper space close to the cylindrical casing with built-in burner, igniter and motor, as well as the space inside the handle that holds the main body can be used effectively. The gas flow path opening / closing means and the electric circuit opening / closing means are short in the connection of the piping and cords of the gas flow path and are easy to turn.

  In particular, the upper space portion and the lower space portion are arranged in a straight line in the handle, and unlike the space portion in which the handle is vertically divided, the handle is not thickened and the gas cylinder can be attached and detached. It will be easy.

  Moreover, since the partition plate that partitions the upper space portion and the lower space portion is used as a connecting portion between the gas flow path opening / closing means side and the gas discharge portion of the gas cylinder, the partition plate is simply used as a partition member for the upper and lower space portions. In addition to the above function, it has a function as a reinforcing material for preventing deformation and deflection of the handle and a function as a connecting portion of the gas flow path.

  The gas cylinder is detachably inserted from the lower space of the handle and is held by a holder provided on the inner wall of the handle, so that the gas cylinder is prevented from being detached (dropped out) and is stable when installed. Can be held.

  Furthermore, since the overall length of the gas cylinder is set to be longer than the storage space length of the lower space part, when the gas cylinder is attached or detached, the lower part of the gas cylinder can be held and operated, and the lowermost end of the gas cylinder is placed in the lower storage space part. There is no such thing as being unable to be taken out due to slipping in, and conversely, when the gas cylinder is installed, there is no case where the grip area of the gas cylinder is reduced and the gas cylinder cannot be reliably installed.

  In addition, since the battery that supplies the drive power to the motor is housed in the space storage section at the bottom of the cylindrical casing, this space storage section can hit other equipment or equipment when the main body is carried or used. It becomes a difficult position and does not cause poor contact of the battery, and the space storage portion is protected from an impact from the outside.

  Since the longitudinal cross-sectional shape of the cylindrical casing is circular or elliptical, the space storage portion of the battery is formed in an arc shape along the outer wall surface shape of the cylindrical casing. The part can be integrated with the external shape of the cylindrical casing, and the image of the strange overhanging part can be removed.

  In addition, since the space storage part is detachably provided with a detachable boat bottom-shaped cover, the inside of the cover in the shape of the boat bottom is the battery storage part, and the boat bottom shape is the appearance of the cylindrical casing Match the shape.

  Further, a handle is pivotally supported on a bulging portion provided at a lower portion of the cylindrical casing, and the space storage portion is positioned in a gap between the handle formed by the bulging portion and the cylindrical casing when the handle is bent. Therefore, even when the handle is folded, the handle does not hit the space storage portion, and the bulging portion of the cylindrical casing necessary for making the handle foldable is used to make the space storage portion An arrangement area (space) can be secured.

  Further, an operating projection is provided on a slide knob for operating the gas flow path opening / closing means and / or the electric circuit opening / closing means provided on the front wall of the handle, and when the handle is bent, the gas flow opening / closing means and the electric circuit opening / closing means can When the road is closed and / or when the power is cut off, the operation projection is positioned in a recess provided in the cover of the space storage unit, so that the slide knob may be accidentally moved when the handle is folded when being carried. Thus, the gas flow path is not opened, the motor rotates, and the igniter does not perform an ignition operation.

  Since the movable range of the slide knob is the side wall of the handle on the upper space side excluding the lower space in which the gas cylinder is stored, no external force is applied to the gas cylinder when the slide knob is operated. Of course, it is important to take out the gas cylinder from the lower space of the handle when carrying it, but it is also necessary to assume that the user has neglected to take out the gas cylinder. .

  In addition, since the longitudinal direction of the rod-shaped on-off valve is arranged in the longitudinal direction of the handle, it has a shaft and is not restricted by the longitudinal dimension of the on-off valve, which has a rod-like shape in terms of function and configuration, and is thick enough to grip the handle. In addition, the hold body, which is originally reduced in function and structure, is arranged in the handle by arranging it so that the sliding direction of the spindle of the hold body intersects with the longitudinal direction of the handle. There are no special restrictions. At the same time, the sliding movement of the slide knob in the vertical direction can be transmitted to the spindle of the holding body without using many link mechanisms, so that the cause of failure can be reduced and the assembly can be simplified.

  Since the slide operation of the slide knob presses the spindle via the arm lever, a small slide operation can be amplified and transmitted to the spindle by the arm lever, which means that the slide stroke of the slide knob by the finger can be reduced. The operability is improved.

  Furthermore, by providing an elastic part in the area of the arm lever that presses the tip of the spindle, it softens the impact when the arm lever and the tip of the spindle hit momentarily as the slide knob slides. Prevents arm lever breakage, breakage and hold body failure.

  Further, since the arm lever is made of synthetic resin, the impact with the slide knob and the spindle is somewhat mitigated as compared with the case of metal.

  Since the elastic portion is formed by a notch provided in a part of the arm lever, it is possible to soften the impact between the arm lever and the spindle without using a special part.

  Furthermore, since the arm lever is pivotally supported at one end and the other end is free, and the other end of the free is linked with a slide knob, the small slide operation of the slide knob is amplified by the arm lever, The movement can be reliably transmitted to the spindle.
