FIG. 2 is a characteristic diagram comparing the power suppression effect of LED lighting of the high-frequency heating device with a range hood in the same embodiment as that of a conventional lighting device. FIG. 3: shows the schematic circuit diagram of the control circuit of the switching power supply of the high frequency heating apparatus with a range hood in the embodiment.

1, a microwave oven 8 with a range hood (a high-frequency heating device with a range hood) is attached above a gas stove 11 (a lower cooking device). The upper part of the microwave oven 8 with the range hood is provided with a circulation fan, and the generated gas generated from the gas stove 11 taken from the generated gas inlet 7 opened at the lower portion of the microwave oven 8 with the range hood is attached with the range hood. The air is exhausted outside through an exhaust passage 9 provided on the back side of the microwave oven 8.

In the main body of the microwave oven 8 with a range hood, there is provided a heating chamber 1 in which a high-frequency cooked food 16 such as food is stored and heated. Inside the main body of the microwave oven 8 with a range hood, along with the heating chamber 1, a machine chamber 17 is provided, and a magnetron 3 (high frequency generating means) is arranged. High-frequency radio waves in the 2.45 GHz band generated by the magnetron 3 propagate through the waveguide 14 and are supplied into the heating chamber 1.

The heating chamber 1 has a substantially rectangular parallelepiped shape, and a door (not shown) is provided at the front opening so as to be opened and closed. The wall of the heating chamber 1 is provided with a plurality of interior illumination holes 15 formed so as not to leak high frequency radio waves. Adjacent to these interior illumination holes 15, LED illumination 4 as an interior illumination device is provided outside the wall surface. This LED illumination 4 illuminates the inside of the heating chamber 1 through the interior illumination hole 15 so that the user can check the progress of cooking.

At the bottom of the microwave oven 8 with a range hood, an LED illumination 5 is provided as a downward illumination device that illuminates the gas stove 11. This LED illumination 5 uses a light emitting diode. A lower illumination light transmitting window 18 is attached to the bottom wall of the microwave oven 8 with a range hood at the bottom of the LED illumination 5, and the generated gas generated from the gas stove 11 enters the vicinity of the LED illumination 5. It is preventing. The LED illumination 5 is supplied with 12V DC power from the switching power supply 13.

In the present embodiment, the supply voltage to the LED illumination 4 is set to 12V. However, the present invention is not limited to this, and any low voltage power supply having a voltage value lower than about 40V may be used.

The control unit 12 (control means) is provided in the machine room 17, and performs ON / OFF control of the magnetron 3, each

LED illumination

4, 5, and ON / OFF control of the switching power supply 13.

FIG. 2 is a characteristic diagram showing the power suppression effect of the LED illumination of the microwave oven 8 with a range hood. The first example in FIG. 2A shows an operation using a conventional lighting device. Moreover, the 2nd example of FIG.2 (b) has shown the case where the inside lighting apparatus uses a conventional apparatus, and only a downward lighting apparatus is made into LED illumination. The 3rd example of Drawing 2 (c) has shown the case where it is set as LED lighting for both the interior lighting device and the downward lighting device.

The operation and action of the high-frequency heating apparatus with a range hood configured as described above will be described below.

First, when cooking using the microwave oven 8 with a range hood, the high frequency heating cooking thing 16 is accommodated in the heating chamber 1 of the microwave oven 8 with a range hood, the magnetron 3 is operated (operation | movement), and it goes to the heating chamber 1. Supply high frequency radio waves. Thereby, the high frequency heating cooking thing 16 in the heating chamber 1 is heated. At this time, during cooking, the LED illumination 4 as the interior lighting device is turned on, and the control unit 12 turns on the switching power supply 13 to reduce the commercial voltage to 12 V and supply the power to the LED illumination 4. . The LED illumination 4 illuminates the inside of the heating chamber 1 so that the user can check the progress of cooking. And when cooking is complete | finished, the control part 12 turns off the switching power supply 13, and the LED illumination 4 turns off. In FIG. 3, the schematic circuit diagram of the control circuit of the switching power supply 13 of the high frequency heating apparatus with a range hood is shown.

Also, when cooking using the gas stove 11 provided below the microwave oven 8 with a range hood, the LED illumination 5 is turned on to illuminate the cooked food. Further, the LED illumination 5 is turned on for the purpose of using it as an in-kitchen lighting as a kitchen lighting. When the LED illumination 5 is turned on, the control unit 12 turns on the switching power supply 13 and controls to supply a low voltage power supply (for example, 12 VDC) to the LED illumination 5.

The LED illumination 5 is supplied with 12V power and illuminates the lower part of the microwave oven 8 with a range hood. When the LED illumination 5 is turned off, when the LED illumination 5 is turned off, the control unit 12 turns off the switching power supply 13.

In addition, the LED illumination 4 as the interior illumination device may be darker than the LED illumination 5 as the downward illumination device. This is because the LED lighting 4 as the interior lighting device only needs to know the progress of cooking the food being cooked in the heating chamber 1, while the LED lighting 5 as the downward lighting device illuminates the gas stove 11. This is because it is necessary to illuminate the interior of the kitchen. For example, if the LED illumination 5 as the lower illumination device is about 4 W, the LED illumination 4 as the interior illumination device may be about 2 W.

As described above, in the present embodiment, by using the LED illumination 5 as the downward illumination device, the lifetime of the downward illumination device becomes longer and can be used semi-permanently. Therefore, replacement work is not necessary, and usability is improved. .

Moreover, since the power consumption of the high-frequency heating device can be reduced by using the LED illumination 5 as the lower illumination device, the reduced power equivalent can be distributed to the high-frequency heating cooking function and the circulation fan function to improve the cooking performance.

Furthermore, the supply voltage to the lower illumination device can be lowered, and the safety can be improved while simplifying the insulation configuration.

By using LED lighting 4 for not only the lower lighting device but also the interior lighting device, the same effect as that obtained by using the lower lighting device as the LED lighting 5 while using the switching power supply 13 in common is used. More than the effect obtained by using the illumination 5 can be obtained.

Although various embodiments have been described above with reference to the drawings, it goes without saying that the present invention is not limited to such examples. It is obvious for those skilled in the art that variations and modifications of various embodiments, and combinations of various embodiments can be conceived within the scope of the claims. Of course, it is understood that it belongs to the technical scope of the present invention.

Note that this application is based on a Japanese patent application filed on April 20, 2011 (Japanese Patent Application No. 2011-093750), the contents of which are incorporated herein by reference.

As described above, the high-frequency heating device with a range hood according to the present invention can be used not only for home use but also for commercial high-frequency heating devices because the lifetime of the lower illumination device is extended and can be used semipermanently.
