Description

DETAILED DESCRIPTION OF THE INVENTION By attaching an electric heater to the inner wall of the door of an electric oven, etc., the electric heater can be used as an electric stove when the door is open, and when the door is closed. When used as an oven, this heater is an improvement that eliminates the imbalance in heat distribution of conventional ovens.

Conventional electric ovens, especially those with hot air circulation that have a heater and fan at the rear of the heating chamber, have a heat source at the rear and a door at the front, which doesn't provide very good insulation, so they tend to be strong in the back and weak in the front. The front and rear heat distribution becomes unbalanced. On the other hand, the shoe king table found in ordinary homes only has two burners, but when cooking several types of food at once, two burners are often insufficient and inconvenient.

Therefore, the present invention solves this unbalanced heat distribution in the front and back by providing a heater on the inner wall of the door, and at the same time improves this heater so that it can be used as an electric stove when the door is opened, thereby replacing the conventional two-way kitchen. To provide a heating cooker that solves two disadvantages at the same time.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional view of a product showing an embodiment of the present invention, with the door closed, and FIG. 2 shows the door opened.

There is a heating chamber 2 inside the main body 1, and at the back of the heating chamber there is a fan 3 for circulating hot air and a heater 4 provided surrounding the fan. 5 is fan 3
6 is a partition plate for partitioning the heating chamber from the fan and heater. The outer periphery of the heating chamber 2 is covered with a heat insulating material 7 to improve thermal efficiency. 8 is a door attached to the door by a hinge 9 so as to be openable and closable, and 10 is a handle.

The center part of the inner wall of the door 8 is recessed, and a heater 11 is removably provided in this part. 12 is a heat insulating material attached to the back side of the heater 11. 13 and 14
is made of glass, and when the heater 11 is removed, the inside of the heating chamber can be seen from the outside with the door closed.

In the above configuration, the air heated by the heater 4 is blown out from the center of the fan 3 into the heating chamber, hits the door wall, makes a U-turn, and is divided into the upper, lower, left, and right sides of the heating chamber. The air is circulated by being repeatedly blown in through the opening in the partition plate at the rear.

Normally, the temperature of the air circulating here decreases as it moves away from the outlet of the partition plate and approaches the door, but in the embodiment of the present invention, a heater is also provided on the inner surface of the door. Therefore, the temperature of the air does not drop even when approaching the door, and food can be heated evenly in both the front and back.

Furthermore, since the heater 11 can be energized even when the door is open, this heater can be used as a stove when there is not enough stove to cook several kinds of food at once.

If you prepare a separate stove, you will need a place to store it, and it will be difficult to take it out when you want to use it. If you have one, you can use it just by opening the door and turning on the switch, so it is very easy and convenient, and its value is high.

If you simultaneously operate a heater with a large wattage that can also be used as a stove when using it as an oven, there is a risk that the input current will exceed the allowable current of a normal household appliance. In some cases, a circuit configuration may be used in which the heaters 4 and 11 are turned on and off alternately.

As explained above, according to the present invention, it is possible to provide an extremely excellent and easy-to-use heating cooker that is simple and eliminates the imbalance in heat distribution that conventional ovens have, and at the same time is equipped with a spare stove.
