Abstract

PURPOSE:To prevent soups and hot air from directly contacting the motor by mounting a washer pressed into a motor shaft of a turntable so that the washer is press fitted to a choke and fitting an inclined soup receiving plate between the washer and the motor. CONSTITUTION:A rubber washer 15 is pressed into the motor shaft 5 of a motor 6 for rotating a turntable 4, and motor 6 is fitted so that the washer 15 is press-fitted to the choke 7. Thus, boil-spilt soup and hot air are not splashed on the motor 6. Further, an inclined soup receiving plate 16 is mounted between the washer 15 and the motor 6. Thus, in a case where the tight connection between the washer 15 and the choke 7 cannot be maintained, soup caused by boil spilling flows down along the inclined surface of the soup receiving plate 16, and even when hot air leaks, it does not directly hit the motor 6. By the above arrangement, the inferior insulation of the motor and the temperature rise thereof are eliminated and the safety of the device is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating cooker having a high frequency generator for emitting high frequency waves into a heating chamber and a heating device for raising the ambient temperature of the heating chamber, and for heating an object to be heated in the heating chamber. This invention relates to a heating cooker equipped with a rotating turntable.

2. Description of the Related Art In a conventional heating cooker shown in FIGS. 2 and 3, for example, there is a heating chamber 2 inside a main body 1, and a door 3. There is a turntable 4 at the bottom. The turntable 4 is coaxially connected to a motor 6 via a motor shaft 6, and is equipped with a choke 7, a heat insulating plate 8, etc. to prevent radio wave leakage. A gas burner 9 is installed at the rear of the heating chamber 2.
The heated air is sent into the heating chamber 2 by a circulation fan 1o, and the remaining air is discharged to the outside through an exhaust guide 11. The heating chamber 2 is located on the side of the heating chamber 2.
A magnetron 13 and a lance 14 which emit high frequency waves through a waveguide 12 are installed inside.

Problems to be Solved by the Invention However, in such a heating cooker, there are openings in the bottom of the heating chamber 2 and the choke 7 through which the turntable 4 and the motor shaft 5 are passed, so that the food to be heated cannot be boiled. When spillage occurred, it spilled over the motor shaft 5 and onto the motor 6, causing problems such as poor insulation of the motor 6 and sticking of gears. 1. Since the air inside the heating chamber 2 is circulated by the circulation fan 10, the pressure inside the heating chamber 2 becomes high, and the hot air inside the heating chamber 2 leaking from the bottom of the heating chamber 2 and the opening of the choke 7 is transferred to the motor. Increase the temperature of step 6.

There were problems with safety and longevity.

The present invention solves these conventional problems, and aims to provide a cooking device with high safety and stable quality.

Means for Solving the Problems In order to achieve the above object, the heating cooker of the present invention press-fits a washer onto the motor shaft, attaches the motor so that the washer comes into pressure contact with the choke, and installs a motor between the washer and the motor. It has a structure that allows you to access the sloping juice receiving plate.

Function: In the cooking device of the present invention, even if the object to be heated boils over in the heating chamber, the washer press-fitted into the motor shaft prevents the boiling liquid from getting onto the motor. This also eliminates hot air leakage from the heating chamber. Even if there is a gap between the washer and the choke part, the slanted liquid receiving plate prevents boiling liquid and hot air from directly hitting the motor, ensuring high safety and providing all products with stable quality. This has the effect of making it possible.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a front sectional view showing the bottom of a heating chamber of a cooking device according to an embodiment of the present invention. A choke 7 is attached to the bottom of the heating chamber 2 to prevent radio wave leakage. On the other hand, a rubber washer 15 is press-fitted into the motor blade 115 of the motor 6 that rotates the turntable 4, and the motor 6 is attached so that the washer 15 is brought into pressure contact with the choke 7. . By doing this, the boiling liquid and hot air from the heating chamber 2 will not come into contact with the motor 6. Unfortunately, a sloped juice receiving plate 16 is installed between the washer 15 and the motor 6. This is so that if the washer 15 and choke 7 are not in close contact with each other, the boiling liquid will flow down along the slope of the liquid receiving plate 16. Even if hot air leaks, the hot air will not directly hit the motor 6.

Effects of the Invention The heating cooker of the present invention provides the following effects.

(1) By press-fitting the choke and washer, it is possible to block boiled water and hot air from leaking from the heating chamber, so problems such as poor motor insulation and temperature rise are completely eliminated, resulting in high safety and stable quality.

(2) By installing a liquid catcher plate between the washer and the motor, even if a small gap is created between the washer and the choke and boiled water or hot air leaks, it will not directly hit the motor. It has a highly safe structure. It can also act as a heat insulating plate to protect the motor from radiant heat from the heating chamber.

(3) Since the washer prevents hot air from leaking, the heat efficiency in the heating chamber is good, and the cooking time for the object to be heated is shortened, which is economical.
