Description

[Detailed Description of the Invention] The present invention relates to a heating cooker, and in particular improves the structure of the main body to improve ease of assembly.

An example of this type of cooking device is a microwave oven that uses microwaves to cook food.

Such a microwave oven is equipped with a high-voltage transformer and a high-voltage capacitor for supplying high voltage to the magnetron, which is electrically connected to the magnetron for microwave oscillation mounted on the heating chamber side, in the space below the heating chamber in the main body, as well as a high-voltage capacitor for heating. Some devices house components such as a food tray drive motor that is connected to a food tray installed indoors and are mounted and supported on a base.

In the case of a microwave oven with such a configuration, when assembling the heating chamber part and the base, it is necessary to lift the heavy heating chamber part and place it on the base, and it is also necessary to remove the heating chamber side components and electricity. Since it is necessary to perform wiring between the base-side components that are connected to the base side components when both have been assembled,
This work had to be done in a narrow space, and was complicated and time-consuming.

Therefore, in view of the above-mentioned conventional circumstances, the present invention consists of a heating chamber unit to which a heating chamber structure is attached and a base on which the heating chamber unit is placed, forming a part of the main body, and combining these units with each other. The present invention provides a heating cooker that can be easily assembled by raising the heating chamber unit relative to the base. This will be explained based on FIG.

In these figures, 1 is the high-frequency heating device main body, which is composed of a front plate 1A, a rear plate 1B, a base 1C, and a case cover 1D. 2 is a heating chamber in which the food to be heated is placed, 3 is an opening/closing door of heating chamber 2,
Reference numeral 4 denotes a storage space for parts to be described below, which is formed below the heating chamber 2 in the main body 1, 5 supports legs provided at the bottom of the main body 1, and 6, power is supplied into the heating chamber 2 via a waveguide 7. A magnetron serves as a microwave oscillator that oscillates microwaves, 8 is a high-voltage transformer for supplying high voltage to the magnetron 6, and 9 is a high-voltage capacitor, and these magnetron 6, high-voltage transformer 8, and high-voltage capacitor 9 are arranged in the storage space 4. ,
Of these, high voltage transformer 8 and high voltage capacitor 9
is placed on the base 1C and fixed with a fixture. 10 is a turntable on which food is placed;
It is mounted and supported on a rotary plate 11 at the inner bottom of the heating chamber 2 . Reference numeral 12 denotes a motor for rotating the turntable 10, which is disposed within the storage space 4 and is connected to the base 1.
C, and its rotating shaft 12A connects to the shaft 11A of the rotating plate 11 via a coupling 13.
is connected to. 14 is a control board provided with a time display section 14A, a timer knob 14B, an output changeover switch 14C, and a cooking switch 14D for controlling the microwave oven.

In this configuration, a front plate 1A, a rear plate 1B, a heating chamber structure 2A attached between the two plates 1A and 1B, and a heating chamber opening/closing door 3 attached to the front plate 1A.
The heating unit 15 is placed on the base 1C via the lower ends of the front plate 1A and the rear plate 1B, and is fixedly supported in a detachable manner.

Here, the front plate 1A and the rear plate 1B are provided with bent parts 1a and 1b on their outer peripheral edges, respectively, which serve as attachment parts for the case cover 1D and the base 1C.
A has an opening 1c communicating with the heating chamber 2 and the control plate 1.
4 is formed with a window 1d through which control parts are exposed, and a mounting fixture 1 of the opening/closing door 3 is formed on the front surface of the window 1d.
6 and 17 are fixedly mounted spaced apart from each other at the top and bottom. The base 1C is provided with a bent portion 1e on its outer peripheral edge, which serves as a mounting portion for the front plate 1A, the rear plate 1B, and the case cover 1D. The coupling structure between the heating unit 15 and the base 1C is such that the front and rear plates 1A and 1 of the heating unit 15 are inserted along the inner surface of the bent portions 1c and 1c facing each other on one side of the base 1C.
After placing the bent parts 1a and 1b at the lower end of B on the base 1C, as shown in FIG.
The bending portions 1c, 1c and the lower end portions of the front and rear plates 1A, 1B are removably fixed to each other by mounting screws 18 screwed in from the outer surface of the plate c.

Next, in the present invention, notches are provided at both corners of at least one side edge of the base, and at the lower end of the wall opposite to one side of the heating chamber unit, the notches are provided on the side of the notches. The positioning portion is provided with a hook engaging portion that engages with a rising piece provided on a side edge portion located between the notch portions of the base.

That is, in FIGS. 4 to 7, 21 is a notch formed by cutting each corner of the base 1C into a rectangular shape, and 22 is a bent portion at the lower end of one side of the front plate 1A and the rear plate 1B. It is a hook engagement part formed by cutting the inner corner part of 1a into a rectangular shape, and the end surface facing the side of the engagement part is the inner corner of the bent part 1e as a rising piece located on the side of the base 1C. It abuts and locks on the part.

Therefore, when assembling the heating chamber unit 15 and the base 1C, as shown in FIG. It can be placed in a predetermined position on the base 1e by pulling it up in the direction of arrow A in the figure from the engaged state.

Incidentally, when the heating chamber unit 15 is placed on the base 1C and tilted in the direction of arrow B shown in FIG. The heating chamber unit 15 rotates approximately at the center, and can be tilted toward the microwave oven mounting surface 23 as shown in FIG.
Maintenance and inspection of the component parts on C can be easily performed.

According to the above configuration, by rotating and raising the heating chamber unit 15 with respect to the base 1C,
The heating chamber unit 15 can be easily set at a predetermined position on the base 1C, and the troublesome work of lifting the heavy heating chamber part and placing it on the base as in the past can be eliminated, and the heating chamber unit 1
Wiring can be done between the components on the heating chamber 2 side and the components on the base 1C side before the assembly of 5 and the base 1C is completed, and this work can be done in a wide open space, making the work much easier. does not become complicated.

Incidentally, according to the above configuration, the heating chamber unit 15
By rotating and defeating base 1C,
Since the space above the base 1C can be opened, maintenance and inspection of the high voltage transformer 8, high voltage capacitor 9, etc. on the base 1C can be easily performed. It is not necessary to take the trouble to remove the wiring connecting the magnetron 6, etc. of the heating chamber unit 15, and the power supply can be checked.Also, since there is no need to remove the heating chamber unit 15 and place it in a separate position, a large space is required for its installation. The advantage is that there are no problems.

As explained above, according to the present invention, the hook engagement portion of the heating chamber unit is engaged with the rising piece provided on the side edge of the base, so that the heating chamber unit is rotated with respect to the base. Because of this, no special parts are required as a rotating means, and the base and heating chamber unit can be easily separated due to the simple structure, resulting in the effect that maintenance and inspection work is extremely simple.
