Description

[Detailed description of the invention] This invention relates to a so-called steam oven that cooks the object by filling the heating chamber with steam.It increases the temperature inside the heating chamber during cooking to improve cooking performance and improve efficiency. Its main purpose is to supply cooking equipment.

In conventional steam cookers, in order to raise the temperature inside the heating chamber during steam cooking, the oven box forming the heating chamber, the door, the gap between the door and the oven, the exhaust port, etc. are formed without any gaps.

As a result, if a gap were created, water vapor would gush out from the gap and adhere to the electrical components inside the main body, causing insulation failure.

Furthermore, in order to eliminate the gap, silicone putty or the like must be applied to the joint between the two metal sheets in the heating chamber, for example.

Therefore, the present invention solves the above-mentioned problems in a simple manner, and an embodiment of a steam cooker equipped with a high-frequency heating device will be described below with reference to the drawings.

Inside the main body 1, there is a heating chamber 3 in which the heated v02 is stored and cooked.

4 is a drainboard on which the object to be heated is placed. On the upper wall 5 of the heating chamber, there is a power feeding lower that feeds the high frequency waves oscillated by the magnetron 6 into the heating chamber.

Note that the power supply lower and the magnetron guide high frequency waves through a waveguide 8, and a cover 9 made of a dielectric material is fixed with screws 10 to prevent food particles from entering the power supply lower.

The upper wall of the heating chamber is also provided with an exhaust port 11 for discharging water vapor generated within the heating chamber during high frequency operation. There is an exhaust guide 12.

A shutter 13 is provided in the exhaust guide 12 to prevent water vapor from escaping during steam cooking.

There is a spout 15 on the side wall 14 of the heating chamber that spews out steam.
Water placed in the water tank 16 enters the boiler 18 through a pipe 17.

This boiler 18 has a metal tank 19 and a sheathed heater 20.
When the sheathed heater 20 is energized, the water 21 boils and becomes steam, which is ejected into the heating chamber 3 through the spout 15 through the pipes 22, 23, and 24. The object to be heated 2 is then cooked.

Here, the pipes 22 and 24 are made of a material such as silicone rubber, but the pipe 23 is made of metal and is brazed and fixed to the sheathed heater 20 of the boiler 18, so that the steam coming out of the boiler ``Heated, high-temperature steam will be ejected into the heating chamber.

Note that 25 is a cock for draining water in the boiler 18.

As is clear from the above explanation, since the pipe connecting the boiler 18 and the heating chamber 3 is fixed to the heating device of the boiler 18 to raise the temperature of the steam coming out, the following effects can be expected.

1. Because the temperature of the steam is high, the temperature in the heating chamber rises quickly, making cooking possible in a short time and efficient.

2. In the conventional method, the shutter attached to the exhaust port is sealed in order to raise the temperature of the heating chamber.

Alternatively, putty is applied to the connecting portion 26 between the heating chamber side wall 14 and the upper wall 5.

It was necessary to take measures such as applying putty to the power supply port cover 9 and then fixing it with screws, but with the present invention, the temperature of the heating chamber can be raised without the above measures, and work efficiency is significantly improved.

In conjunction with 32, when the heating chamber is sealed, the water vapor pressure within the heating chamber increases, and if even a slight gap is created, water vapor will be ejected from the gap.

There are many high-pressure parts in the high-frequency heating device, and if this ejected steam adheres to these parts, the insulation resistance will decrease and cause defects.

In the present invention, there is no need to seal the shutter or the like, so the water vapor pressure in the heating chamber is not high, and there is almost no leakage of water vapor, eliminating the cause of defects in electrical parts.
