The present invention relates to a stirrer cover of a microwave oven, and in particular, by quickly discharging dry air flowing into the stirrer cover installed on the upper surface of the cooking chamber to the outside of the cooking chamber, the humidity sensor installed at one side of the cooking chamber accurately maintains humidity. It relates to an exhaust structure of a stirrer cover of a microwave oven so that it can be sensed.

In general, a microwave oven is a multi-purpose bar that is equipped with a grill heater, a convention heater, and a convection fan in addition to a magnetron as a heating means. By driving the convection fan installed at the rear of the convection heater at the same time by the convection motor, the hot air is circulated inside the cooking chamber to cook by the oven function.

However, the conventional microwave oven is reflected at a constant angle when the high frequency is reflected on the inner wall of the cooking chamber to reflect the high frequency radiated from the magnetron to the inside of the cooking chamber to cook food. . There is a problem in that the food is locally heated because the high frequency is irradiated to a specific portion of the food.

Therefore, in order to solve the above problems, a stirrer cover (STIRRER COVER) having a built-in stirrer pan is attached to the upper surface of the cooking chamber so that the high frequency is dispersed while the auxiliary iron piece inserted therein is rotated when the stirrer pan rotates. Public utility model publication No. 92-4772 has been proposed as a technique for preventing food from being locally heated by reflecting it, and there was also a method to prevent the phenomenon of high frequency concentration by placing food on a rotating tray. Such prior art configurations have the following problems.

first ; The structure with a stirrer cover with a stirrer pan installed on the upper surface of the cooking chamber can effectively inject high frequency to prevent the local heating of food.However, the method of driving the stirrer pan is the electric room. It rotates by using the dry wind generated from the cooling fan installed at the rear, and this wind flows into the cooking chamber through the exhaust port of the stirrer cover formed in communication with the cooking chamber after driving the stirrer fan installed at the stirrer cover. Since the steam generated from food is pushed down and discharged into the exhaust hole drilled on the right side wall of the cooking chamber, the humidity sensor installed at the rear of the exhaust hole does not detect the exact amount of water vapor because the dry air is mixed with the steam. According to the food heating time could not be properly adjusted.

second ; Therefore, in view of such a problem, the microwave is mainly used to prevent the high frequency partial concentration phenomenon by rotating the tray on which the food is placed, but the food placed on such a rotating tray is always rotated constantly. Therefore, the local heating of the food to some extent can be prevented, but the partial heating of the food cannot be prevented.

Therefore, the present invention was devised to solve the above-mentioned problems, and the humidity sensor installed on the right side of the cooking chamber accurately corrects the amount of water vapor while preventing the partial concentration of high frequency by using a stirrer cover in which a stirrer fan is installed. It is an object of the present invention to provide a stirrer cover exhaust structure of a microwave oven so that it can be detected.

The present invention for achieving the object as described above, in the conventional attaching the stirrer cover with the stirrer fan on the upper surface of the cooking chamber of the microwave oven, the exhaust induction pipe is isolated from the cooking chamber in the exhaust port of the stirrer cover It is formed to extend, and to form a discharge hole separately in the upper surface of the cooking chamber in which the exhaust induction pipe is characterized in that the air is discharged to the upper surface of the cooking chamber.

Hereinafter, with reference to the accompanying drawings, the crew cover exhaust structure of the microwave oven according to the present invention will be described.

As shown in FIG. 1, the stirrer cover 3 of the microwave oven according to the present invention has a stirrer cover 4 in which a stirrer pan 4 is formed in the cooking chamber 1 and the upper surface 2 of the microwave oven. ), The exhaust inlet 5 of the stirrer cover 3 extends the exhaust induction pipe 6 which is isolated from the cooking chamber 1, and at the time of cooking in which the exhaust induction pipe 6 is located. (1) The discharge hole 7 is formed separately in the upper surface 2 so that the air is discharged to the upper surface 2 of the cooking chamber 1.

In the figure, reference numeral 17 is a cooling fan, 8 is a magnetron, 9 is a duct, 10 is a tray, 11 is an air inlet formed in the stirrer cover 3, (12) is an auxiliary iron piece inserted in the stirrer pan (4), (13) is an upper suction hole formed in the left wall of the cooking chamber (1), (14) is a lower suction hole, and (15) is a humidity sensor. .

Looking at the operation and effects of the present invention configured as described above are as follows.

Part of the wind generated by the cooling fan 17 arranged on the rear side of the battlefield cools the magnetron 8 attached to the right side wall of the cooking chamber 1, and then the duct 9 and the lower suction hole 14 of the right side wall of the cooking chamber. The water vapor is introduced into the cooking chamber 1 through the discharge chamber through the outlet formed in the left side wall of the cooking chamber 1 so that the humidity sensor 15 attached thereto detects the amount.

A portion of the wind generated by the cooling fan 17 is transferred to the stirrer cover 3 through the upper suction hole 13 of the right side wall of the cooking chamber 1 and the air inlet 11 of the stirrer cover 3. As it flows in, the auxiliary iron piece 12 inserted into the stirrer fan 4 with the high frequency generated by the magnetron 8 is effectively rotated by rotating the stirrer fan 4 built in the stirrer cover 3. Reflect them so that they are evenly cooked.

Thereafter, the wind in which the stitcher fan 4 is rotated as described above is introduced into the exhaust induction pipe 6 that is isolated from the cooking chamber 1 through the exhaust port 5 of the stirrer cover 3, thereby exhausting the induction pipe 6. ) Is quickly discharged to the outside of the cooking chamber 1 through the discharge hole (7) drilled in the upper surface (2) of the cooking chamber (1).

Accordingly, the air introduced into the stitcher cover 3 is discharged to the discharge hole 7 drilled in the upper surface 2 of the cooking chamber 1 through the exhaust induction pipe 6 formed to be isolated from the cooking chamber 1 as described above. Since it is discharged quickly, dry wind, which rotates the stirrer pan 4 as in the related art, is introduced into the cooking chamber 1 through the exhaust port 5 to prevent diffusion of food vapor from the food, and is produced in the food. Humidity sensor (15) installed on the rear of the outlet accurately detects the amount of water vapor and the heating time of the food, since the water vapor is discharged through the discharge hole drilled in the left wall of the cooking chamber without being affected by the dry wind. It is possible to cook properly.

As described in detail above, the present invention forms an exhaust induction pipe that is isolated from the cooking compartment at the exhaust port of the stirrer cover, thereby effectively separating the wind from the cooling fan flowing into the cooking compartment from the cooking compartment and quickly discharging it to the outside during cooking. Due to this, the humidity sensor installed on the right side of the assembly chamber can accurately detect the amount of water vapor, and can effectively cook the whole food by effectively reflecting the high frequency generated from the magnetron, thus improving the quality and efficiency of the microwave oven. It can be, and thereby has the effect to meet the consumer's desire to buy.
