Description

[Detailed Description of the Invention] This invention relates to an electric steam oven in which a water tank can be attached and detached using a cassette system, and heat resistance has been taken into consideration to enable the use of inexpensive materials.

Conventionally, many steam ovens have a structure in which a part of the exterior is removed or a water tank is inserted using a lid, making it difficult to check the amount of water from the outside and whether or not water is being used. It is inconvenient, it is not easy to attach or detach the aquarium, and some of the aquariums are not removable, and it is troublesome to handle such as pouring water into the aquarium with a pitcher.The temperature of the boiler room and cooking room increases, causing the aquarium, etc. However, since it is exposed to high heat, it has disadvantages such as being easily damaged if manufactured from cheap materials (such as plastic).

This invention proposes an electric steam oven aimed at eliminating the above-mentioned drawbacks, and one embodiment thereof will be described below based on the drawings.

FIG. 1 is a front view showing the electric steam oven of this invention, FIG. 2 is an enlarged vertical sectional view showing the main parts of the same, and FIG. 3 is an explanatory view seen from the side of FIG.

As shown in the figure, this idea is installed in the steam generator of a steam oven, in which water is collected from a water tank through an automatic tap, stored in a level cup, and then supplied to the boiler room through a water supply pipe, which is fixedly installed above one side of the steam oven. , and an aquarium cassette stand 3 having an insertion hole 1 bored in the bottom according to the position of the nozzle part of the aquarium, and a plurality of aquarium support protrusions 2 at the four corners of the bottom, and an upper end on the circumference of the insertion hole 1. Interval 3
1 and a metal tube 5 which is fitted and inserted and whose lower end is supported by a lower level cup 4 is provided. Then, the cassette-type aquarium 6 is placed on the aquarium cassette stand 3 and its automatic stopper 7
Insert the aquarium nozzle part 8 having an annular hole 9 into the metal tube 5 from below.
is inserted, and the lower surface of the cassette type aquarium 6 is supported by the aquarium support protrusion 2 to support the aquarium cassette stand 3.
The aquarium cassette table 3 is characterized in that it is placed with a space 10 on the bottom surface and that a hot air outflow passage 11 is bored in the aquarium cassette stand 3 to communicate the space 10 with outside air.
In addition, 12 is the aquarium opening, and 13 is the level cup 4.
a mandrel 14 that protrudes inside and pushes up the automatic stopper 7;
15 is the water supply pipe, 15 is the boiler body, 16 is the cooking timer, 17 is the control panel, 18 is the steam selector switch, 19 is the door, 20 is the water droplet tray, 2
1 is a leg/saucer shelf, 22 and 23 are handles, 24 is a top cover plate, 25 is a side cover plate, 26 is a cooking chamber 27 and a water supply chamber 2
The cassette type water tank 6 is made of a permeable material such as transparent plastic. Further, the automatic stopper 7 has a valve body fixed to one end of the valve stem inserted into the water tank nozzle part 8, one end supported by the outer peripheral surface of the water tank opening 12, and fixed to the other end of the valve stem. When placing the cassette-type aquarium 6 on the aquarium cassette base 3 or carrying it around, the self-weight of the automatic stopper 7 and the aquarium 6 are used. The valve body closes the water tank opening 12 by the water pressure inside and the restoring force of the spring member.

In the above steam oven, when the cassette type water tank 6 is placed on the water tank cassette stand 3 from above with the water tank opening 12 facing down, it automatically comes into contact with the stem 13 of the level cup 4 installed below, and the automatic stopper 7 Aquarium opening 1 is pushed up by a certain amount
Open 2. The water flowing out from the opening and injected into the level cup 4 flows into the boiler body 15 through the water supply pipe 14, and when the water level reaches the same level as the water level in the level cup 4 as shown in the figure, the water flow stops. With the above steps, steam can be generated. After that, the boiler body 15 is heated with a heater, and steam is introduced into the cooking chamber 27 through a pipe. At this time, the water level in the boiler body 15 decreases by the amount of evaporation, but the water level in the boiler body 15 is constantly lowered from the cassette type water tank 6. is replenished, the water level in the level cup 4 and the water level in the boiler body 15 are maintained at the original water level (height up to the lower end of the cassette type water tank 6), and steam is generated satisfactorily for use.

During use, the temperature in the boiler room 30 and the cooking chamber 27 rises, and high heat is transmitted into the water supply chamber 28 through the partition plates 29 and 28, respectively, but the heat is transmitted through the bottom of the water tank cassette stand 3, and The hot air passes through the space 31, passes through the space 10 and the hot air outflow passage 11, and escapes to the outside of the oven. In addition, the water tank nozzle part 8 of the cassette type water tank 6 is shielded from heat by a metal tube 5, and the hot air generated from above the level cup 4 is passed through the annular air 9, the space 10, and the hot air outflow passage 11 to the outside of the obre. to escape. Therefore, the inside of the water supply chamber 28 does not reach a high temperature, and the equipment is not exposed to high heat.

When injecting water into the cassette-type water tank 6, lift it upwards and quickly unfit it, and insert it into the water supply from the automatic faucet 7 side with the water tank opening 12 facing up (in the figure, with the water tank nozzle section 8 removed). Pour water from the faucet. Then, as before, insert the aquarium cassette base 3 from above.

According to this invention, as mentioned above, the water tank is a cassette type and has a structure that allows high heat to escape to the outside of the oven, making it easy to attach and remove the water tank and pour water into the tank, making it easy to handle. It is convenient to be able to check the water level in the water supply room, and the equipment in the water supply room will not be exposed to high heat due to the rise in temperature in the boiler room and cooking room, making it possible to use inexpensive materials such as plastic, and it is also possible to partition each room. The diaphragm is also useful because it can be made thinner without requiring as much thickness as the conventional one, and because it does not require expensive heat insulating material, the manufacturing cost is very low, and it also looks good.
