Description

Vibration noise prevention structure of the bottom of the cooking chamber of the microwave oven

The present invention relates to a microwave oven for heating and cooking food by using a high frequency oscillated from the magnetron, in particular in a microwave oven formed by forming a machine room containing components such as a high frequency oscillation device and a high-pressure transformer at the bottom of the cooking chamber of the microwave oven The present invention relates to a vibration noise preventing structure of the bottom of a cooking chamber of a microwave oven, which has a bead shape protruding downward from the bottom of the cooking chamber to reduce vibration generated from components such as a high-voltage transformer of a machine room.

In general, microwaves project microwaves (high frequency of 2450 MHz) oscillated in a magnetron to food (dielectric), so that the molecules of food are active in collision with each other according to the frequency of the projected microwaves. It generates heat and cooks it by heating.

As shown in FIGS. 1 and 2, the microwave oven is connected to the cavity 10, the front panel 20, the back panel 30, the base panel 40, and the outer panel 50. The cooking chamber 60 for heating and cooking, and the machine chamber 70 in which various core parts of the microwave are disposed in the lower portion of the cooking chamber 60.

The high pressure transformer 71 installed in the base panel 40 and the lower side of the cooking chamber 60 are installed in the machine room 70 so as to generate a high voltage electricity by receiving power from a power supply device. A magnetron 72 for generating a high frequency by receiving a high voltage of the waveguide and a waveguide that is bound to an outer wall of the cooking chamber 60 to guide the high frequency generated in the magnetron 72 through an upper wall of the cooking chamber 60. 73).

A control panel 120 is attached to the front of the machine room 70, and a cooking type is selected according to various operation modes of the microwave oven, and the output and cooking time are adjusted according to the cooking type. The control unit 121 is formed.

At the bottom of the cooking chamber 60, a seating part 62 is formed on which a cooking dish 61 for placing food is placed, and a door 100 for opening and closing the opening of the cooking chamber 60 in the front of the cooking chamber 60. ) Is fixedly attached to the hinge (110).

When the food is to be cooked using the microwave oven, first, the door 100 is opened, food is placed on the upper surface of the rotary dish 90 in a balanced manner, and then the door 100 is closed, and then the control of the control panel 120 is performed. When the cooking button or the cooking time of the food is selected by pressing the cooking button of the unit 121 and pressing the start button, a high voltage is generated in the high voltage transformer 71, and the magnetron received the high voltage of the high voltage transformer 71. 72 generates high frequency.

The high frequency oscillated by the magnetron 72 is introduced into and out of the cooking chamber 60 through the upper wall of the cooking chamber 60 according to the guide of the waveguide 73. By evenly infiltrating and absorbing the inside of the food on the upper surface, the thermal energy conversion is made inside the food and the food is heated and cooked.

However, in the microwave oven configured as described above, the machine room 70 is formed under the cooking chamber 60, and vibration caused by the magnetic force formed in the high pressure transformer 71 among the various components in the machine room 70 is caused by the cooking chamber. There was a problem that is transmitted through the bottom surface of (60).

That is, since the seating portion 62 on which the plate 61 of the cooking chamber 60 is mounted is flat, vibrations due to magnetic force generated when the various components of the machine chamber 70 are operated are transmitted. .

Therefore, the present invention is devised to solve the above problems, the object of the present invention is to prevent vibration vibration noise prevention structure of the cooking chamber of the microwave oven to prevent the vibration caused by the magnetic force generated in the parts in the machine room. To provide.

In order to achieve the above object, in the microwave oven, the bottom part of the cooking chamber of the microwave oven according to the present invention, the microwave oven is configured to form a seating portion lower than the bottom of the cooking chamber so that the cooking dish is seated on the bottom surface of the cooking chamber. It is characterized by comprising a plurality of closed curve bead to the lower side of the seating portion of the cooking chamber.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same parts as in the conventional construction are denoted by the same reference numerals and detailed description thereof will be omitted.

3 and 4, the cooking chamber for heating and cooking food by the combination of the cavity 10, the front panel 20, the back panel 30, the base panel 40 and the outer panel 50 ( 60) and a machine room 70 in which various core parts of the microwave are disposed in the lower part of the cooking chamber 60.

The high pressure transformer 71 installed in the base panel 40 and the lower side of the cooking chamber 60 are installed in the machine room 70 so as to generate a high voltage electricity by receiving power from a power supply device. A magnetron 72 for generating a high frequency by receiving a high voltage of the waveguide and a waveguide that is bound to an outer wall of the cooking chamber 60 to guide the high frequency generated in the magnetron 72 through an upper wall of the cooking chamber 60. 73).

On the bottom surface of the cooking chamber 60, a seating portion 62 is formed lower than the bottom of the cooking chamber 60 so that the cooking dish 61 is seated, and the seating portion 62 of the cooking chamber 60 is positioned downward. Many closed curve beads 62a protrude.

The closed curve bead 62a has a circular edge shape.

Next, the operation and effect of the present invention configured as described above will be applied to generate a high voltage in the high voltage transformer 71, and the magnetron 72 receiving the high voltage of the high voltage transformer 71 generates high frequency. do.

The high frequency oscillated by the magnetron 72 is introduced into and out of the cooking chamber 60 through the upper wall of the cooking chamber 60 according to the guide of the waveguide 73. By evenly infiltrating and absorbing the inside of the food on the upper surface, the thermal energy conversion is made inside the food and the food is heated and cooked.

In particular, the high-pressure transformer 71 is installed in the lower portion of the cooking chamber 60 so that the magnetic force generated in the high-voltage transformer 71 directly hits the bottom surface of the cooking chamber 60, the cooking chamber 60 The closed curve bead 62a is projected to the bottom of the bottom to reinforce the strength of the bottom surface of the cooking chamber 60, and the magnetic force line of the high-voltage transformer 71 strikes the closed curve bead 62a to the machine room 60. Vibration of the components in 70 is not transmitted.

As described above, according to the vibration noise prevention structure of the bottom of the cooking chamber of the microwave oven according to the present invention, by forming a closed curved bead protruding downward on the bottom surface of the cooking chamber formed on the upper side of the machine room in the high-voltage transformer in the machine room There is an effect that the vibration caused by the generated magnetic force is not transmitted to the cooking chamber.
