The heat generation at 20 is stopped. The temperature sensor 28 may be installed anywhere in the inner surface of the cooking chamber 12, for example, both sidewalls, the upper surface, and the bottom surface, as long as the temperature sensor 28 is electrically connected to the electric heater 20 so as to sense the temperature in the cooking chamber 12. The temperature sensor 28 may be composed of a thermistor, PTC, NTC, and the like, and in the present embodiment, the thermistor.

Meanwhile, the control panel 30 is provided with various function buttons for performing general cooking setting and convection cooking setting, and a controller (not shown) for controlling opening and closing of the damper 14 according to the convection cooking setting. And electrically connected to the convection fan 22.

The control panel 30 is provided with a hand drying selection button 32 for setting the hand drying function. The hand drying selection button 32 is electrically connected to the control unit, and when the hand drying selection button 32 is set by the user, the intake and exhaust holes 12A and 12B for the air flow in the cooking chamber 12 are It is closed by the damper 14 under the control of the controller.

The control panel 30 is provided with an adjustment button 34 for controlling the rotational speed of the convection fan 22. The adjustment button 34 is electrically connected to the convection fan 22, and the voltage supplied to the convection fan 22 is adjusted according to the strength and weakness of the adjustment button 22 through pre-input information. The rotation speed of 22 is controlled. By controlling the rotation speed of the convection fan 22 by the control button 22, the intensity of the hot air blown into the cooking chamber 12 is adjusted.

On the other hand, the auxiliary door 42 is installed in the front center area of the door 40 to be opened and closed.

The operation of the heat transfer heater 20 and the convection fan 22 is controlled according to the received information.

That is, the hand drying selection button 32 is set by the user, and when the auxiliary door 42 is opened, the electric heating heater 20 and the convection fan (by the control panel 30) receiving the signal of the detection sensor 44 ( 22) is activated. On the other hand, when the auxiliary door 42 is closed, the operation of the heat transfer heater 20 and the convection fan 22 is stopped by the control panel 30 that receives the signal from the detection sensor 44.

Referring to the operation of the convection microwave oven having a hand drying function according to a preferred embodiment of the present invention configured as described above are as follows.

Convection microwave oven having a hand drying function according to a preferred embodiment of the present invention is the intake port (12A) and the air flow is generated in the cooking chamber 12 when the cooking of the general food by the ultra-high frequency generated by the action of the magnetron Opening the exhaust port 12B to the damper 14 under the control of the control unit to form a flow path for cooling air, thereby increasing the cooling effect on the magnetron, and the damper 14 to discharge moisture generated in the cooking process to the outside. To open.

On the other hand, when the convection cooking function is in progress by the operation of the electric heater 20, the damper 14 is controlled according to the control of the controller so that the air flow in the cooking chamber 12 is blocked in order to raise and maintain the temperature inside the cooking chamber 12. The food intake is cooked using the hot air blown into the cooking chamber 12 by the heat transfer heater 20 and the convection fan 22 by closing the inlet 12A and the exhaust port 12B. At this time, the surface of the food is heated by hot air.

On the other hand, when removing the water of the hand after cooking or washing dishes, as shown in Figure 3, when the user presses the hand drying selection button 32 of the control panel 30 generates air flow in the cooking chamber 12 Intake / exhaust ports 12A and 12B which are opened as much as possible are simultaneously sealed by the damper 14 under the control of the controller.

In this state, when the user opens the auxiliary door 42 installed to be opened and closed on the door 40, the heat transfer heater 20 is heated by the control panel 30 electrically connected to the detection sensor 44, and at the same time, the convection fan. 22 is rotated and hot air is generated. At this time, the hot air is blown through the cooking chamber 12 toward the outlet of the auxiliary door 42 to dry the hand so that water is removed.

When the user continuously adjusts the intensity of the hot air while drying the water of the hand, the strength and weakness of the adjustment button 34 provided in the control panel 30 is adjusted. Then, the voltage supplied to the convection fan 22 is adjusted according to the strength and weakness of the adjustment button 34 to control the rotation speed of the convection fan 22.

Therefore, the user can adjust the intensity of the hot air blown toward the user through the outlet of the auxiliary door 42 according to the strength, weak control of the adjustment button 34 as desired.

On the other hand, when the temperature of the hot air blown toward the user through the outlet of the cooking chamber 12 and the auxiliary door 42 is raised above the set temperature, the temperature in the cooking chamber 12 by the temperature sensor 28 provided in the cooking chamber 12 Is detected. At this time, the temperature sensor 28 cuts off the power supplied to the electric heater 20. Then, the heat generation of the heat transfer heater 20 is stopped and only the air by the convection fan 22 is blown toward the user, thereby preventing burns that may occur during drying of the hand.

When the water of the hand is completely removed through the above process and the user closes the auxiliary door 42, the control panel 30 stops the rotation of the convection fan 22 according to the signal of the detection sensor 44.

When the hand drying function is set by the user, the convection microwave oven having such a hand drying function is controlled by the control unit so that the air flow in the cooking chamber 12 is blocked according to the setting of the hand drying selection button 32. 12A and 12B are sealed by the damper 14, and when the auxiliary door 42 is opened, the heat transfer heater 20 is heated by the control panel 30 electrically connected to the detection sensor 44, and the convection fan 22 is closed. The hot air generated by the rotation is blown toward the outlet of the auxiliary door 42 to be dried to remove water from the hand.

As described above, the convection microwave oven having a hand drying function according to the present invention sets a hand drying selection button according to the hand drying function when the user wants to remove water after cooking or washing dishes. By opening the air circulation path in the cooking chamber can be sealed and at the same time it can be easily dried to remove the hand water by using the hot air generated by the operation of the heat transfer heater and the convection fan. In addition, by sterilizing the bacteria of the hand by the hot air of the high temperature is to provide an effect that can implement a clean kitchen environment through the suppression of bacterial growth.

The present invention has been described in the above embodiments, but the present invention is not limited to the above-described embodiments, and those skilled in the art without departing from the gist of the present invention claimed in the claims. Anyone could make a variety of variations.
