    Air intake of microwave
    The present invention relates to a microwave oven, and more particularly, to an air intake port of a microwave oven that sucks air for cooling the inside of an apparatus room.
    In general, a microwave oven is a cooking apparatus capable of cooking food using microwaves in a short time, and microwaves generated from a magnetron to which high voltage is applied are irradiated into the food inside the cooking chamber through a waveguide. By vibrating the water molecules contained in the food to generate heat energy, the food is heated and cooked therein.
    Such microwave ovens can cook various foods in various ways by appropriately adjusting the microwave output and the time that the microwaves are irradiated to the food. In addition, the microwave can be used to heat foods that have already been cooked or to melt frozen food Can be used.
    An example of such a microwave oven is shown in FIG. 1. Referring to this, the configuration and operation of the microwave will be described briefly as follows.
    As shown in the drawing, the microwave oven includes a cabinet assembly 10 divided into two spaces, a cooking chamber 10a having an open front surface thereof, and a chamber 10b in which various electric devices are installed, and the outside of the cabinet assembly 10. It is attached to the outer panel 20 that forms the appearance of the microwave oven, the door 30 for opening and closing the front of the cooking chamber 10a, and the front of the apparatus chamber 10b so that the user can set various cooking conditions. The panel 40 is comprised.
    The tray 50 is provided on the bottom surface of the cooking chamber 10a, and the food to be cooked is placed in the tray 50. The lower device chamber 10b has a magnetron 61 for generating microwaves, a high voltage condenser 62, a high voltage franchose for generating a high voltage of approximately 2100 to 2400 VAC required by the magnetron 61 and the high voltage condenser 62, and the like. Various electrical devices such as a low voltage transformer (not shown) for generating a low voltage of 110 or 220 VAC or less and a normal commercial AC voltage (110 or 220 VAC) and supplying them to the cooling fan 64 are provided. A cooling fan 64 for cooling the electric devices inside 10b is provided inside the air inlet 11 of the cabinet assembly 10 that forms the rear surface of the device room 10b.
    As shown in more detail in FIGS. 2 and 3, the air inlet 11 is located at the rear of the apparatus chamber 10b of the cabinet assembly 10 and has a net shape in which a plurality of small through holes are densely formed. have.
    In addition, a plurality of discharge holes 12 are formed in the lower plate of the cabinet assembly 10 forming the bottom surface of the device chamber 10b for discharging air inside the device chamber 10b to the outside.
    In this way, the food is placed in the tray 50 placed on the bottom surface of the cooking chamber 10a, and then the operating panel 40 is operated to set cooking conditions and operate the microwave oven. Due to the high voltage, microwaves are generated in the magnetron 61. The microwaves are guided into the cooking chamber 10a and irradiated to the food placed in the tray 50 so that the food is heated and cooked by the microwaves.
    At this time, the cooling fan 64 is also operated while the magnetron 61 is operated. Accordingly, the air outside the apparatus chamber 10b is sucked into the apparatus chamber 10b through the air inlet 11 so that the apparatus chamber 10b is operated. After cooling the various electric devices inside, it is discharged to the outside of the device chamber 10b through the discharge hole 12.
    However, since the amount of air sucked into the interior of the equipment room through the air inlet is not enough to reduce the temperature required by the electric devices inside the equipment room, the temperature level inside the equipment room is high. There was a high risk of overheating of the electrical devices inside the equipment room.
    SUMMARY OF THE INVENTION The present invention has been made in view of the above, and provides an air inlet of a microwave oven capable of increasing the amount of air sucked into the device room so as to cool the electric devices inside the device room more efficiently. There is this.

    The above object is to form a rear surface of a device chamber in which devices such as a magnetron for generating microwaves and a high voltage transformer for applying a high voltage to the magnetron are installed, and air is introduced into the device chamber by a cooling fan installed therein. According to an embodiment of the present invention, in the air inlet of the microwave oven, the plurality of small through-holes are densely formed so as to be sucked, and having a pair of inclined surfaces formed to be inclined inwardly toward a position corresponding to the rotation axis of the cooling fan. Achieved by the air intake of the stove. Here, the pair of inclined surfaces are preferably symmetrical with respect to the rotation axis of the cooling fan.
    According to the present invention as described above, since the amount of air sucked into the interior of the equipment room by the rotation of the cooling fan is made of a pair of inclined surfaces of the left and right symmetry, for various electrical devices installed inside the equipment room Cooling efficiency is also improved. Therefore, it is possible to prevent overheating of the electric devices inside the device room.
    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    4 shows an air inlet of the microwave oven according to the present invention.
    As shown, the air intake port 11 of the microwave oven according to the present invention has a pair of inclined surfaces 11a symmetrical to each other and has a net shape in which a plurality of small through-holes through which air passes is densely formed. It is formed integrally under the back plate of the cabinet 10 so as to form a rear surface of the device chamber 10b in which devices such as the one or more are not installed. The pair of inclined surfaces 10a are symmetrical with respect to the rotational axis of the cooling fan 64 installed inside the air inlet 11, and have a shape inclined inward toward the rotational axis of the cooling fan 64, respectively. .
    In this way, when the air is sucked into the inside of the apparatus chamber 10b by the rotation of the cooling fan 64 by the operation of the microwave oven, the inclined surface 11a of the air inlet 11 is opened. Accordingly, since air flows into the center side of the cooling fan 64, the amount of air sucked through the air inlet 11 is increased.
    On the other hand, the pair of inclined surfaces 11 may be formed not only left and right symmetry, but also up and down symmetry, but when the pair of inclined surfaces are symmetric, the amount of air sucked is greatly increased.
    The air intake port of the microwave oven according to the present invention as described above is composed of a pair of inclined surfaces of which the shape is symmetrical, so that the amount of air sucked into the inside of the room by the rotation of the cooling fan increases, it is installed inside the room Cooling efficiency for various electrical devices is also improved. Therefore, it is possible to prevent the electric devices inside the device room from overheating.
    Although specific embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention belongs to the present invention without departing from the gist of the present invention as claimed in the claims. Anyone of ordinary skill in the art will be able to implement various modifications.
