Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a configuration diagram showing a mounting structure of a heat dissipating device for a microwave oven according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a heat dissipating device for a microwave oven according to an embodiment of the present invention.

1 and 2, the heat dissipation device for a microwave oven according to an embodiment of the present invention is installed in the magnetron 30, the water tank 50, the cooling water is fresh water, and the supply pipe for supplying the cooling water to the water tank (50) 52 and a drain pipe 54 for discharging the cooling water discharged from the water tank 50 to the outside of the cabinet 10.

When the cooking operation is started after storing the food in the cooking chamber 12, microwaves generated from the magnetron 30 are irradiated into the cooking chamber 12 along the waveguide, so that the food is heated while the moisture contained in the food is vibrated. Will be done.

In this case, high heat is generated in the magnetron 30 that produces microwaves, and the electric cooler 14 absorbs heat generated from the magnetron 30 and discharges it to the outside of the cabinet 10. It becomes possible to prevent overheating more than necessary.

The water tank 50 is formed of a polygon that is in close contact with the outer wall of the magnetron 30, the cooling water fresh water in the water tank 50 along the supply pipe 52 is a water tank 50 in close contact with the top, bottom and both sides of the magnetron 30 As it passes through, it effectively absorbs heat discharged from the magnetron 30 to perform a heat radiating operation.

The shape of the water tank 50 is formed to be in close contact with the top, bottom and both sides of the magnetron 30 to form a rectangle, and the shape of the water tank 50 in the shape of a container, the top, bottom, both sides and bowel movement of the magnetron 30. It can be modified to be in close contact with the.

The shape of the water tank 50 can be changed in various ways, which can be easily changed and implemented by those skilled in the art that recognizes the technical configuration of the present invention will not be described in detail or the description of the other embodiments.

Since the heat dissipation fins 70 are installed on the outer wall of the water tank 50, the outside air introduced into the electric chambers 14 by a cooling fan (not shown) installed in the electric chamber 14 passes between the heat dissipation fins 70. The heat of the magnetron 30 transferred to the cooling water is absorbed and discharged to the outside of the cabinet 10.

Since the outside air introduced into the electric compartment 14 by the cooling fan is directly in contact with the surface exposed to the outside of the water tank 50 in the outer surface of the magnetron 30, the magnetron 30 is formed by cooling water. The heat dissipation operation and the heat dissipation operation by the outside air are simultaneously performed.

Looking at the operation of the heat sink for a microwave oven according to an embodiment of the present invention configured as described above are as follows.

When the user opens the door of the cooking chamber 10 to store food in the tray 16 and then closes the door and starts cooking, microwaves are irradiated from the magnetron 30 into the cooking chamber 12 to proceed with cooking. .

At this time, since the tray 16 is rotated by the driving unit 18, microwaves are uniformly irradiated on the whole food, and the food is heated while the moisture contained in the food is vibrated to perform the cooking operation.

During the cooking operation as described above, the high temperature heat is generated in the magnetron 30, and the heat of the magnetron 30 is transferred to the cooling water freshwater inside the water tank 50 along the supply pipe 52.

Cooling water absorbing heat from the magnetron 30 is discharged to the outside of the cabinet 10 along the drain pipe 54 to perform a heat radiation operation.

Therefore, the heat dissipation operation of the magnetron 30 can be performed by the cooling water irrespective of the temperature of the external air introduced into the electric compartment 14 by the cooling fan.

In addition, when the temperature of the outside air introduced into the interior of the electric compartment 14 by the cooling fan can perform a heat radiating operation, the outside air is in contact with the heat radiating fins 70 and absorbs heat from the cooling water to double the heat radiating efficiency. The effect is shown.

In addition, while the outside air introduced into the electric compartment 14 is in direct contact with the magnetron 30, the second heat dissipation operation is performed.

Cooling water in the water tank 150 is changed to a state of the cooling water in a portion of the steam by the high heat transmitted from the magnetron 130, the steam generated in the interior of the water tank 150 along the delivery pipe 156 cooking chamber 112 ) Is supplied internally.

Therefore, the amount of cooling water drained to the outside of the cabinet 110 along the drain pipe 154 is reduced, and it is possible to perform steam cooking to inject steam and heat food.

Since the heater 158 for heating the steam supplied from the water tank 150 is installed in the delivery pipe 156, the steam supplied from the water tank 150 may be heated to perform effective steam cooking, and the temperature of the delivery pipe 156 may be increased. When is increased, a larger amount of cooling water may be injected into the cooking chamber 112 without being discharged along the drain pipe 154.

Of course, it is preferable that the distance between the heater 158 and the magnetron 130 is sufficiently long so as to prevent heat generated from the heater 158 from being transferred to the magnetron 130.
