  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a steam cooker according to an embodiment of the present invention.

  The steam cooker 1 includes a tray 10 that holds food, a case 20 that houses the tray 10, and a plurality of steam nozzles 30 that supply steam into the case. The steam cooking device 1 of the present embodiment includes two trays 10 and two cases 20, and FIG. 1 shows a state in the middle of housing one tray 10 in the case 20. The numbers of trays 10 and cases 20 are not particularly limited, and may be one or three or more, respectively.

  2 and 3 are a plan view and a side view of the tray 10, respectively. The tray 10 includes a casing 12 having a rectangular shape in plan view having an opening at the top, and a handle portion 14 connected to the casing 12 via a cover plate 13. The housing 12 includes a bottom plate 12a, a pair of long side walls 12b, 12b and a pair of short side walls 12c, 12c provided along the edge of the bottom plate 12a. The long side walls 12b and 12b are made of a net material, while the pair of short side walls 12c and 12c are made of a thin plate. The material of the housing 12 is not particularly limited, but by using titanium or a titanium alloy, the work load can be reduced by reducing the weight, and durability, corrosion resistance, antibacterial properties, and the like can be improved. . Although there is no restriction | limiting in particular also about the foodstuff accommodated in the tray 10, For example, frozen noodles, such as pasta, udon, and soba, refrigerated raw noodles, vegetables, etc. can be mentioned.

  The case 20 can store the tray 10 in the storage space 22 through the opening 21 formed on the front surface. By pushing the tray 10 from the state shown in FIG. Is in contact with the periphery of the opening 21 to seal the storage space 22 and is positioned so that the tray 10 is positioned in the center of the case 20. A drain port 23 is formed on the bottom surface of the case 20, and a support member 24 that supports the bottom plate 12 a of the tray 10 is disposed.

  The steam nozzle 30 has a plurality of injection holes 30 a formed along the axial direction, and is disposed so as to extend in the horizontal direction in the storage space 22. As shown in a longitudinal sectional view in FIG. 4, the steam nozzles 30 are arranged at intervals in the vertical direction along the left and right inner walls of the case 20 so as to inject steam toward the center of the storage space 22. Further, the respective injection holes 30a are opposed to each other. With such an arrangement of the steam nozzle 30, a pair of left and right injection units 31, 31 are configured. The tray 10 is held between the pair of injection units 31 and 31 with the outer surfaces of the pair of long side walls 12b and 12b spaced apart from each other by the same degree as the outer surface of each steam nozzle 30. .

  The injection direction from the injection hole 30a is preferably a direction in which steam can be uniformly supplied to the food F held on the tray 10, and in this embodiment, all are horizontal, Depending on the height position, it may be diagonally upward or diagonally downward.

  The steam nozzle 30 is connected to a steam generator (not shown) that generates steam by heating. In this embodiment, a boiler-type steam generator that generates steam by heating water in a tank with a heater is used to stably supply steam. However, the configuration of the steam generator is not particularly limited, and other known configurations such as a dropping type that instantaneously generates steam by injecting water onto a heated hot plate may be employed. A solenoid valve is interposed in the flow path connecting the steam generator and the steam nozzle 30, and the solenoid valve is operated by operating the operation panels 40, 40 arranged on the front side of the steam cooker 1. The high temperature steam can be injected into the storage space 22 of the case 20 for a predetermined time.

  A cleaning nozzle 33 is disposed in the upper center of the storage space 22 so as to extend in the horizontal direction, and the cleaning nozzle 33 is an injection hole 33a along the axial direction so as to inject hot water or steam downward. A plurality of are formed. The cleaning nozzle 33 is connected to a steam generator (not shown) in the same manner as the steam nozzle 30 so that water or high-temperature water is sprayed into the storage space 22 together with the steam by opening and closing the electromagnetic valve. Is possible.

  According to the steam cooker 1 of the present embodiment, when the tray 10 holding the food F is accommodated in the case 20 and the spray of steam is started by the operation of the operation panel 40, as shown in FIG. The jetting units 31 and 31 jet steam from the outside to the long side walls 12b and 12b, respectively. Since the long side walls 12b and 12b are made of a net material, the jetted steam passes through the long side walls 12b and 12b and is supplied to the left and right of the food F. Thus, since the steam can be injected from both sides of the food F, the contact area between the food F and the sprayed steam can be increased as compared with the conventional configuration in which the steam is injected only from above the food F. The food can be efficiently heated in a short time. The steam sprayed onto the food F is condensed to become waste water, is discharged through the bottom plate 12a made of a net material, and is collected from the drain port 23 on the bottom surface of the case 20.

  When the steam cooker 1 shown in FIG. 1 was actually prototyped and the frozen noodles were thawed, the thawing time was about 20 seconds, compared with the conventional machine that required 40-50 seconds to defrost. As a result, it was possible to reduce the thawing time to less than half. In addition, since the electric capacity of this prototype is the same as that of the conventional machine, it was possible to save power by shortening the thawing time.

  In the steam cooker 1 of the present embodiment, the pair of long side walls 12b and 12b function as a pair of holding plates that allow the steam to pass and hold the food F therebetween. Such a pair of holding plates only need to have a communicating hole through which steam passes, and can be composed of, for example, various mesh materials such as wire mesh, metal lath, punching metal, and expanded metal. When the tray 10 has a general shape including a rectangular housing in plan view, as in the present embodiment, by forming a communication hole in the long side wall 12b to function as a holding plate, Compared with the case where the side wall 12c is used as the holding plate, the contact area between the food F and the sprayed steam can be increased, which is preferable. However, the shape of the tray 10 is not necessarily a housing shape, and may be configured such that only a pair of holding plates is provided on the bottom plate as long as the food F can be reliably held.

  In addition to injecting steam from the pair of injection units 31, 31, the steam cooker 1 of the present embodiment can also inject steam from the cleaning nozzle 33. In this way, by causing the cleaning nozzle 33 to function as an auxiliary injection unit, it is possible to inject steam from the left and right sides and the upper three directions, thereby further increasing the heating efficiency. Note that when steam is injected from below the food F, waste water mixed with a part of the food F falls to the nozzle due to gravity, and the injection hole is likely to be clogged. Preferably not.

  Moreover, in this embodiment, although the installation height of each steam nozzle 30 in a pair of injection parts 31 and 31 is set so that it may become the same height on right and left, the steam nozzle 30 is set in the height position which is different on right and left. May be installed. For example, as shown in FIG. 5, the vapor nozzle 30 of the other injection unit 31 is disposed at the same height as the center of the two vapor nozzles 30, 30 adjacent in the vertical direction in the one injection unit 31. Also good.

  Further, the configuration of the pair of injection units 31 and 31 is not limited to that of the present embodiment, and may be configured by jackets 34 and 34 disposed on the left and right sides of the case 20 as shown in FIG. Then, by forming the injection holes 34a, 34a in a matrix shape on the wall surface of the case 20 so as to communicate with the jackets 34, 34, the steam is injected from both sides of the food F as in the configuration of the present embodiment. Can do.
