Description

Microwave with service structure of machine parts

The present invention relates to a microwave oven, and more particularly, to a microwave oven having an electronic component service structure of a microwave oven whose structure is improved to facilitate replacement or repair of the electric component mounted on the upper portion.

Various kinds of apparatuses have been proposed to date as heating apparatuses for heating foods. The most basic heating device has a container in intimate contact with the heat source, it is possible to cook food by putting the contents to be cooked in such a container and applying heat.

In addition, many types of cooking apparatuses that use electric energy directly or indirectly have been developed. As an example, a microwave oven using microwaves as a heating source can be cited. A microwave oven is a cooking apparatus that generates microwaves using electricity to infiltrate a cooking object and heat the cooking object by causing molecular motion therein. The microwave is generated by an electric component including a magnetron.

Hereinafter, a mounting position and a service structure of a conventional electronic component will be described with reference to the drawings.

1 shows the electric component mounting position of the microwave oven as described above.

In the microwave oven, between the front plate (1) forming the front surface and the back plate (2) forming the rear surface, the cavity (3), which is a space where food is heated, and the electric compartment (4) on which the electronic components are mounted, have a side (T). Divided by

An upper passage plate portion 5 is formed in the upper portion of the front plate 1 to serve as an air passage passage between the outside and the inside of the microwave oven.

In addition, an exhaust motor assembly 7 having intake ports at both ends is installed at the upper surface of the cavity 3 in the direction of the rear plate 2 so as to suck in ambient air and discharge it to the outside.

The electric parts cooled by the operation of the exhaust motor assembly 7 are mounted in the electric compartment 4. In detail, the magnetron 10 generating microwaves is attached to the side of the electric chamber (T), and the waveguide 11 connected to one end of the magnetron 10 guides the microwaves into the cavity 3. The other end is connected to the upper part of the cavity (3).

Electronic components including a high voltage transformer 11 in which high pressure is induced to generate microwaves in the magnetron 10 and a high voltage capacitor 12 in which a high voltage is charged are included in the bottom plate 15 below the electric chamber 4. It is mounted on and fixed.

The electric chamber 4 having such a configuration generates heat in the electric component when microwaves are generated. In particular, the magnetron 10 and the high voltage transformer 11 generate more heat than other components. Due to such high heat, the possibility of malfunction of the electrical component is increased, and a service structure for repairing and replacing the electrical component is required.

2, a microwave oven having a conventional electronic component service structure will be described.

Door 20 for opening and closing the cavity is installed on the front plate (1). And, as shown in the front of the electric compartment 4, the control panel 22 is mounted. The control panel 22 is formed on the front of the control operation unit, including the operation button, the control part is installed on the back.

In addition, the vent grill 25, which serves as a passage for the air flow path, is installed at the top of the door 20 and the control panel 22 in the flow passage hole 5 formed in the front plate.

In the microwave oven having the above configuration, the electronic component service sequence is as follows.

Loosen the screw connecting the vent grill 25 and the front plate 1, and disassemble the vent grill 25 and the front plate (1). Then, the control panel 22 is disassembled from the front plate 1, so that service is possible to the front of the electric compartment 4.

When the control panel 22 is removed to secure the service room 4, the reason for disassembling the vent grill 25 first is that the fastening part of the control panel 22 is covered by the vent grill 25. to be.

However, nowadays, a microwave oven having a structure in which the electric component is mounted on the upper part of the electric compartment 4 is used.

Such a microwave oven can maximize the utilization of the space of the electrical compartment 4 by mounting the electronic components including the magnetron 10 and the high voltage transformer 11 on the upper electrical compartment 4, and also, the exhaust motor assembly ( 7) The cooling efficiency is improved by being installed close to.

However, the following problems occur in the electronic component service structure having the above structure.

As shown in FIG. 2, when the vent grill 25 and the control panel 22 are separated from the front plate 1, and the electrical components are to be taken out through the upper part of the electric chamber 4, the upper part of the electric chamber 4 and The space formed in the corresponding front plate 1 was narrow, and troubles occurred in the service of the electrical equipment.

That is, in the conventional structure, the electrical components mounted on the upper part of the electrical compartment 4 are front plates.

Interference with (1) occurred, and there was no space for the electrical component to be taken out to the front. As a result, when replacing and repairing electronic components, service time is increased because all external cases must be removed to service electronic components.

Accordingly, an object of the present invention is to provide a microwave oven having an electronic component service structure of a microwave oven, in which the service time is reduced by providing an easy electronic component service structure as described above.
