Description

[Detailed description of the invention] This invention provides a heating chamber in the combustion chamber with a water receptacle for steam generation and a water tank provided in an insulated chamber adjacent to the combustion chamber. A flow path switching cock is installed in the water supply pipe that communicates the dish section and the feeder tank, and by switching this cock, steam cooking with water supply, high-temperature cooking without water supply, In addition to making it possible to drain water from the pan, the drain generated on the inner surface of the front door attached to the heating chamber is collected into the pan by a train collection guide plate installed on the lower inner surface of the front door. This allows it to be used for re-evaporation.

An embodiment of the present invention will be described below.

That is, in the figure, 1 is a heating chamber provided in a thermal combustion chamber A.

28 is a bottom plate base that supports the heating chamber, 3 in Fig. 2
7 is a heat shield plate provided between the combustion chamber A and the adjacent heat insulation chamber B, 6 is a water tank installed in the heat insulation chamber B, 30 is a temperature control circuit device, 29 is a timer, 12 are gas valves, both of which are provided within the heat insulating chamber B.

34 indicates the cabinet body.

In this configuration, the heating chamber 1 is heated by a so-called indirect heating method in which the peripheral wall of the heating chamber 1 is heated from the outside and the food 26 on the saucer 24 is heated with the heat.

Therefore, a waste gas guide plate 8 is provided on the outer periphery of the heating chamber 1 so as to maintain a predetermined gap, and the combustion gas passes between this guide plate and heats the bottom and peripheral side walls of the heating chamber 1. from the cabinet body 34 through the exhaust grill 9.
Expelled outside.

A heat insulating material 21 is provided on the outside of the waste gas guide plate 8 in order to prevent heat from being radiated to the outside and heat the outside, and to improve the thermal efficiency of the heating chamber 1.

Further, the inner bottom of the heating chamber 1 is formed into a concave shape, and a dish portion 2 is formed therein to receive the evaporated water.

The water receptacle 14 is a cover removably attached to the dish portion 2, and has a hole for blowing out steam.

16 is the front door of the heating chamber 1, which is made of transparent heat-resistant tempered glass 1.
7 is used, and a guide plate 22 for drain collection is provided on the inner surface of the lower part of the door 16 so that the water receptacle is located above the dish part 2 and protrudes so that the tip side is inclined downward. The water drain from the inner side of the door, which is particularly noticeable, is collected by the guide plate 22 into the tray 2 and used for re-evaporation.

The operation of the cooking device according to the invention will be explained below.

That is, water is supplied from the water supply tank 6 to the dish portion 2 through a reservoir 3 that receives water from the water supply tank 6 and maintains the water level at a constant level, and from there, through a flow path switching cock 5 and a water supply pipe 4 in a straight line. This is done through the water supply port 38 of the dish portion 2, which is located at a location that is not directly heated by the flame of the burner 10.

Therefore, when the water in the pan 2 evaporates and the water level drops, the water level in the reservoir 3 will also drop, and water will be supplied from the water tank 6 to compensate for the drop, keeping the water level in the pan 2 constant at all times. .

Further, the flow path switching cock 5 provided in the middle of the water supply pipe 4 is formed by a plug body 39 with holes on three sides and its outer shell case 40 as shown in FIG. Accordingly, each of the above holes is connected to the water supply port 3.
8 and the nozzle 3, the water supply port 38 and the external discharge port 41. Alternatively, the reservoir 3 and the external discharge port 41 may be communicated with each other, so that the water receiver can supply water to the dish portion 2 and drain water therefrom or from the reservoir 3 as desired. It is made possible.

Therefore, by switching the flow path switching cock 5, it is possible to perform steam cooking using the steam generated from the dish portion 2, high-temperature cooking without using this steam, and drainage during cleaning of the water supply system.

Note that the drainage from the drain port 41 directly enters the drain tray 15.

In addition, the temperature inside the heating chamber 1 is adjusted by detecting the internal temperature of the heating chamber by a temperature sensing element 31 installed inside the heating chamber 1, and by using a temperature control circuit device 30 installed between the gas valve 12 and the main burner nozzle 13, for example, using an electromagnetic device. valve 32 to 0
The N-OFF operation is performed to maintain a predetermined set temperature.

As described above, the present invention is such that the water receiver for steam cooking is provided in the heating chamber in the dish part, the water supply tank for this dish part is provided in the insulation chamber adjacent to the combustion chamber that accommodates the heating chamber, and the dish part is provided in the heating chamber. The water supply pipe that connects the water supply tank and the water supply tank is equipped with a flow path switching cock, so by simply switching this cock, you can not only steam cooking or high-temperature cooking without steam, but also use the water receiver for dishes, water tanks, reservoirs, etc. It has the practical benefit of being able to drain water very easily when cleaning as desired each time, and the whole can be made compact, and the inner surface of the front door where the occurrence of drainage is noticeable. Therefore, the water receiver has the advantage that the drain can be collected in the dish portion and re-evaporated for use without causing the drain to leak out of the cooking device.
