The steam generator for steaming rice cake according to the present invention, as shown in Figures 4 and 5, is provided with a rice cake base plate 5 on which the rice cake base (D) is placed. The rice cake base plate 5 is formed in a rectangular frame shape having a predetermined height so that steam is diffused to the bottom of the rice cake base D. The rice cake base 5 is placed on the opening / closing member 4 provided with the steam discharge valve 6.

The opening and closing member 4 is formed to open and close the upper part of the housing 1 in which the water storage tank 1b is incorporated. The opening / closing member 4 is fixed by the locking means 20 so that steam inside the reservoir 1b does not leak out. The packing 22 is assembled in the upper part of the housing | casing 1 in which the said water tank 1b was provided so that the opening-and-closing member 4 may be in close contact. As the packing 22, a silicone material, a rubber material, or the like may be used. The steam discharge valve 6a is attached to the opening / closing member 4 which sealed the water storage tank 1b.

As shown in FIG. 6, the valve body 24 is assembled by using the packing 22 in the opening / closing member 4 corresponding to the reservoir 1b position as shown in FIG. 6. The valve body 24 has a hollow nut 26 formed at a lower end thereof, and an insertion hole 30 into which the valve body 28 is inserted is formed at the upper end thereof. The steam injection hole 36 is formed in the valve body 28 at the bottom of the nozzle plate 34 in which the mist spray hole 32 was formed. Thereby, the valve body 28 can blow off steam in the form of mist and steam. The valve body 28 is screwed to the hollow nut 26 so as to withstand the high pressure of the water storage tank 1b, and is double-fastened by the hollow bolt 38. As shown in FIG.

The housing 1 having the opening / closing member 4 installed thereon may be manufactured in a single type in which one reservoir 1b is installed and in a plurality of types in which two reservoirs 1b are provided. The water storage tank 1b may add or subtract quantity as needed. The housing 1 is equipped with a control box 44 having an operation switch 40, an operation lamp 42, and the like on its front surface to operate the reservoir 1b. The operation switch 40 and the operation lamp 42 of the control box 44 are set in two sets so as to independently operate the plurality of reservoirs 1a. The operation switch 40 controls the operation of the steaming steam generator, and the operation lamp 42 displays the operation state of the operation switch 40.

In addition, the housing 1 has a water supply valve 50 for supplying water by the float 48, in addition to a discharge valve 46 installed to communicate with the bottom of the reservoir 1b to facilitate the discharge of water during washing. It is installed. In addition, a water supply pipe 52 to which the water supply valve 50 is connected is equipped with a filtration device 8 for filtering water supplied to the water storage tank 1b.

The reservoir 1b is equipped with an electric heater 3 that generates heat by an ON operation of the operation switch 40, and a hot water sensor 54 capable of sensing the temperature of the heated water. It is installed.

The water storage tank 1b is provided with a bottom plate 56 forming a bottom. In the bottom plate 56, two fixed side plates 58 are disposed on the upper side so that two surfaces thereof face each other. The bottom plate 56 and the fixed side plate 58 are welded (W2) from the outside to the edges in contact with each other in the form of an unprocessed plane. And, between the fixed side plate 58, the variable side plate 60 is disposed so as to absorb the expansion pressure in the reservoir 1b and the contact portion is welded from the outside.

The variable side plate 60 is provided with a bent portion 70 at the edges of the three sides to absorb the expansion pressure. Said variable side plate 60 is welded so that it may become the form which entered the inside of the water storage tank 1b by the bending part 70. FIG.

Thereby, in the inside of the water storage tank 1b, the variable expansion part 72 which the bent part 70 of the variable side plate 60 abuts on the fixed side plate 58 without being welded to the inner side surface is formed. The variable expansion portion 72 allows the variable side plate 60 to be easily pushed out when the pressure inside the reservoir 1b increases.

The variable side plate 60 formed in the water storage tank 1b may be formed at least one or more of five surfaces, and the bent portion 70 formed therein may absorb internal pressure within a predetermined range. It becomes about.

Since the reservoir 1b is made of stainless steel, the inside is clean, and there are no welding marks on the corners of the inside, so that the water tank 1b can be cleaned as well as the contamination of the water.

Hereinafter, the effect | action of this invention made as mentioned above is demonstrated.

First, the steam-generating device for rice cake steaming will be described by taking an example in which one storage tank 1b is installed because the operations are all made the same even if several storage tanks 1b are installed.

The water supplied from the water supply means through the water supply pipe 52 is filtered by the filtration device 8 and then stored in the water storage tank 1b.

When the water is stored in the reservoir 1b, the operation switch 40 of the control box 44 is turned on to check whether the operation lamp 42 is operated normally.

The electric heater 3 which is turned on by the operation switch 40 heats the water inside the reservoir 1b. The water level of the water is detected through the water level sensor 54, the water supply when the sound is generated.

Steam is generated when the water in the reservoir 1b is heated by the heat generated by the electric heater 3. The steam is ejected to the bottom surface of the rice cake base (D) placed on the rice cake base plate (5) through the steam discharge valve (6a) mounted on the opening and closing member (4). At this time, the steam discharge valve 6a ejects steam through the steam injection hole 36, and sprays the mist through the mist injection hole 32 of the nozzle plate 34.

That is, the mist spray hole 32, so that the rice cake evenly reaches the top of the nozzle plate 34 so that the steam in the form of mist is properly reached.

The steam formed inside the water tank 1b is sealed by the opening / closing member 4 and is discharged through the steam discharge valve 6a. At this time, the reservoir 1b receives a strong expansion pressure when the internal pressure rises due to steam. As a result, the variable side plate 60 of the water storage tank 1b is deformed while the bent portion 70 of the variable expansion portion 72 formed at the edge is opened as the expansion pressure is applied to the central portion.

In other words, the reservoir 1b is convexly deformed to the outside by the expansion pressure therein, so that the reservoir 1b can withstand the strong expansion pressure therein without being damaged.

When the expansion pressure in the reservoir 1b is released, the bent portion 70 of the variable side plate 60 is restored by the high elastic modulus.

The reservoir 1b has a long life as it is formed in a structure in which the volume is variably changed by internal pressure.

The steam generator for steaming rice cake, after use, stops the operation switch 40 by turning off and separates the rice cake base and the rice cake base plate 5 placed on the opening / closing member 4.

Then, the discharge valve 46 is opened to discharge the water contained in the water reservoir 1b, and then the locking means 20 is released to open and close the opening and closing member 4.

As described above, since the reservoir 1b opened by the opening / closing member 4 is made of stainless steel without welding marks, it can be quickly washed with a cleaning tool.

The present invention is to facilitate the cleaning and the contamination of the welding portion to prevent the expansion expansion portion is formed inside to absorb the expansion pressure when manufacturing the water storage tank made of stainless material, it can be widely used in the field of rice cake manufacturing apparatus.
