Description

Wall-mounted Microwave

The present invention relates to a microwave oven, and more particularly, inflow of air by a cooling fan installed in a battlefield compartment separated from a cooking compartment by a partition wall in a cabinet and air inflow of a ventilation fan fixed to a hood motor for ventilation do not interfere with each other. It relates to a wall-mounted microwave oven for preventing.

The conventional wall-mounted microwave oven is installed on the upper wall surface of the gas range, as shown in FIG.

Referring to FIGS. 1 and 2, the conventional wall-mounted microwave oven 10 is a ventilation fan 30 provided at the rear of the upper surface of the cooking chamber 21 formed by the partition wall 24 in the cabinet 20. After inhaling the steam or smoke generated in the gas range provided in the through the connecting pipe (P) connected to the upper side of the ventilation fan 30 has a structure to discharge through the connection passage 40 formed on the wall.

A hood lamp 22 is fixed to the bottom surface of the cooking chamber 21, and a grill 23 for discharging air by the ventilation fan 30 is fixed to the front upper end thereof. The hood motor 31 is fixed to the top rear center of the cooking chamber 21, and the ventilation fan 30 is fixed to the shaft provided in the both sides of this hood motor 31. As shown in FIG.

One side of the cooking chamber 21 is partitioned by a separate partition 24 to inhale steam or smoke from the upper portion of the gas range, and guides the ventilation fan 30 to the upper side, and an electrical equipment room 50 is provided with various electrical appliances. . The magnetron 51 that emits microwaves to the cooking chamber 21 is fixed to the electrical equipment chamber 50 on one side of the cooking chamber 21, and the high voltage transformer 52 is fixed to the lower side of the magnetron 51.

In front of the magnetron 51 and the high-voltage transformer 52, as shown in Figure 3a and 3b, a cooling fan 53 for cooling the high heat generated in the magnetron 51 and the high-voltage transformer 52 is a fan motor ( 54).

When the air is circulated in the conventional wall-mounted microwave oven as described above are as follows.

Steam or smoke generated in the gas range provided at the bottom of the microwave oven 10, as shown in the thick arrow shown in Figure 3b, by operating the ventilation fan 30 provided in the center of the cabinet 20, It is sucked to the lower side of the electric chamber 50 provided on one side. Afterwards it is discharged to the front and rear of the cabinet 20 or is discharged to the outside via the connection passage 40 through the connection pipe (P) provided on the top of the cabinet 20.

In addition, the outside air flows into the grill 23 provided on the front upper end of the cabinet 20 by the cooling fan 53 installed in the electric compartment 50 on one side of the cooking chamber 21 as shown by a thin arrow shown in FIG. 3B. Then, the introduced outside air passes through the magnetron 51 and the high pressure transformer 52 installed at the rear of the cooling fan 53 to cool the high heat generated therefrom.

The air passing through the magnetron 51 and the high-pressure transformer 52 is introduced into the cooking chamber 21 through the air vent of the partition wall 24 partitioning the electric chamber 50 on one side of the cooking chamber 21, and then generated during cooking. It is discharged to the outside through the electric chamber 50 provided on the other side of the cooking chamber 21 together with steam, smoke and smell.

However, according to the conventional wall-mounted microwave oven as described above, the outside air shown by the arrow in Fig. 3b is introduced through the grill 23 of the upper front of the cabinet 20, the magnetron 51 and the high-voltage transformer 52 After cooling the high temperature and entering the cooking chamber 21 and discharged to the outside again, only a part enters the cooking chamber 21 by the operation of the fan 30 and the hood motor 31, and the rest flows into the lower side of the cabinet 20. Together with steam and smoke is discharged to the outside through the upper surface of the cooking chamber (21).

Therefore, the air circulation by the cooling fan 53 for cooling the magnetron 51 and the high-pressure transformer 52 and ventilating the cooking chamber 21, and the ventilation for indoor ventilation to suck in indoor polluted air and discharge it to the outside. Since the air circulation structure by the fan 30 interferes with each other, there is a problem that the performance of the product for ventilation of the cooking chamber 21 and the ventilation of the room is lowered.

Accordingly, the present invention has been made to solve the above-mentioned problems, an object of the present invention, by installing a ventilation fan and a hood motor on the other side of the electrical compartment with a cooling fan and a fan motor to cool the magnetron and high-voltage transformer It is to provide a wall-mounted microwave oven that does not interfere with the air circulation of the cooling fan for ventilating the cooking chamber, and the air circulation of the ventilation fan that enters and purifies indoor polluted air and discharges it to the outside.
