Description

[Detailed Description of the Invention] This invention relates to a steam oven for cooking food by steam heating using an electric heater and high-temperature steam.

Hereinafter, one embodiment of this invention will be explained according to the drawings. In Figs. 1 and 2, 1 is a heating chamber formed in the outer casing 2, and 3 and 3' are the upper and lower parts of this heating chamber. 4 is a table on which the food to be cooked is placed; 5 is a door that freely opens and closes the front opening 6 of the heating chamber 1; 7 is a heating chamber for the heating chamber 1; The heat insulating material 8 provided above the upper surface is a decorative metal arranged along the lower end of the layer 5, and has a small JL9 in the center.

Reference numeral 10 denotes a drain plate provided below, extending from the lower surface of this ornament to the lower surface of the outer casing 2. freely supported.

12 is a steam generator provided on the side of the heating chamber 1;
13 is a steam jetting nozzle penetrating the side wall of the heating chamber 1, and steam from the steam generator is jetted into the heating chamber 1 from this nozzle.

Further, the details of the steam generator are shown in FIG. 3, in which 14 is its water tank, 15 is a water receiver connected to this water tank, 16 is a pipe to which the lower end of this water receiver is connected, Reference numeral 17 indicates a steam generating section that vaporizes water supplied from one end of this pipe, 18 indicates a rod-shaped electric cartridge heater provided within this steam generating section, and 19 indicates the above-mentioned steam generating section 17.
a steam pipe connecting the upper part of the steam pipe to the steam jet nozzle 13;
Reference numeral 20 denotes a cap detachably attached to the end opening of the other end of the pipe 16 extending toward the front of the outer casing 2, and is used to remove water from the steam generating section 17 during cleaning.

In the above-described configuration, when steaming and heating a Kinwa-cooked food, the food is placed on the table 4, the door 5 is closed, and the heaters 3, 3', and 18 are energized.

As a result, the water in the steam generator 17 is heated by the heater 18 to generate steam, which is ejected from the nozzle 13 through the pipe 19 into the heating chamber 1 to steam the food to be cooked.

Further, the above steam is reheated in the heating chamber 1 by the heaters 3 and 3', and as a result, the food to be cooked is steamed and cooked in an even shorter time.

Of course, if the heater 18 is not energized, it can be used as a normal oven.

Here, when steam cooking as described above is performed, if steam hits the inner surface of the door 5, the temperature of this wall surface is relatively low, so it becomes a drain and adheres to the wall surface.

This drain drops down from the upper end of the door 5, is received by a decoration 8, and is collected into a drain plate 10 through a hole 9 of the decoration 8.

This drain is evaporated into the air by radiant heat from the lower surface of the outer casing 2, which is indirectly heated to a high temperature by the heat generated by the heater 3'.

Therefore, according to this invention, it is possible to evaporate the drain collected in the drain pan into the air, thereby reducing the trouble of frequently taking out the drain pan to drain water.Moreover, the temperature is kept at a relatively high temperature by the heater. Even if no heat insulating material is provided on the lower surface of the outer casing, the influence of heat on the stand on which the steam oven is placed is reduced, and the so-called heat insulating material is made to serve as a drain plate, so that the manufacturing material cost can be reduced accordingly.

[Brief explanation of drawings]

FIG. 1 is a side sectional view showing an embodiment of this invention, FIG. 2 is a front view with the door removed, and FIG. 3 is a sectional view showing the steam generator with the device removed. In addition, the same reference numerals in the figures indicate the same parts, 2 is the outer casing, 1 is the heating chamber, 12 is the steam generator, 3' is the heater, 5 is the door,
10 is a drain plate.

Claims (1)
