Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency heating apparatus for maximizing output within a limited power consumption range and shortening a food heating time.

[0002]

2. Description of the Related Art At present, in general households, a circuit from a power distribution board is often used at 100 V and 15 A per circuit. Therefore, even when a high-frequency heating device is used, its power consumption is within 1.5 KW. Must be held down. On the other hand, for market needs, it is desired to shorten the heating time, and accordingly, high output is being achieved.

As a means for improving the output efficiency in order to maximize the output within a limited power consumption, it is general to improve the efficiency of the output, as disclosed in Japanese Patent Application Laid-Open No. 2-227988. In addition, there is a method in which a maximum output larger than a normal continuous maximum output can be used within a predetermined time.

[0004]

However, according to the means disclosed in Japanese Patent Application Laid-Open No. Hei 2-227988 described above, the magnetron or the drive unit for supplying power to the magnetron is heated until a predetermined temperature of each element is reached. Since the magnetron generates a maximum output larger than a normal continuous maximum output, a high output cannot always be used when a user wants to use it.

In addition to the power output of the magnetron, the power consumption of a fan motor, a table motor, an interior light, and the like is also included. Therefore, in order to obtain the maximum output within a limited power consumption, the power consumption is also hindered. Becomes

[0006] However, the fan motor is for cooling the magnetron and preventing failure due to the temperature rise of the magnetron, and the table motor is for rotating the food to eliminate uneven heating and to make the food uniform. Also,
The interior light was considered to be indispensable because it illuminates the cooking room and checks the heating status of the food.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a cooking chamber for storing food, a dish on which the food is placed, a heating unit for heating the food on the dish, and a heating unit. A fan motor for cooling the unit, an interior light for irradiating the inside of the cooking chamber, an operation unit for inputting food heating information, and a control unit for controlling the heating unit and the interior light based on information from the operation unit. In the high-frequency heating device, the operation unit is provided with an input unit for a high-output operation for heating with the interior lamp turned off, and an input unit for a normal output operation for heating the interior lamp by turning on the interior lamp. By arbitrarily selecting one of the input units, the output of the heating unit can be changed.

Further, when heating the same food, an appropriate difference in the heating time between when the input section for the high output operation is selected and when the input section for the normal output operation is selected can be automatically corrected by the control section. It is like that.

Reference numeral 4a denotes a high-output operation input unit that does not turn on the interior light 7 even during the heating of the food 1. Reference numeral 14b denotes an input section for a normal output operation for turning on the interior light 7 while the food 1 is being heated.
The input section 14a for the high output operation and the input section 14b for the normal output operation are collectively referred to as the output operation input section 14. Fifteen

Reference numeral 16 denotes a warm input unit operated when starting heating. Reference numeral 17 denotes a cancel input unit operated when an erroneous operation is performed or when heating is stopped halfway.

Reference numeral 18 denotes a function selection unit for selecting whether to heat the food 1 by high-frequency heating or heater heating, or to set the heating time of the food 1. Reference numeral 19 denotes an automatic cooking menu in which a heating method, a heating time, a heating temperature, and the like of the food 1 are preset for each food 1, and a menu group that can automatically set the heating simply by selecting a menu is provided. By the way.

Next, the operation of the embodiment of the present invention configured as described above will be described.

The food 1 is placed on the plate 3 of the cooking chamber 2, and the heating condition of the food 1 is set by the function selecting section 18 of the operation section 9, that is,
Selection of a range by high-frequency heating or an oven by heater heating and setting of the heating time of the food 1 and the like are performed. The results of these settings are displayed on the display unit 13.

Next, the input unit 14a for the high output operation or the input unit 14b for the normal output operation is selected depending on whether the food 1 is to be heated quickly. One of the indicator lamps 15a and 15b is turned on according to the result of this selection. All the input information is sent to the control unit 8.

After the user completes the input information of food 1,
The input section 16 is turned ON. Then, the control unit 8 operates the heating unit 5, the table motor 4, the fan motor 6, and the like according to the information input by the output operation input unit 14, the function selection unit 18, and the like, and the food 1 starts heating.

Here, when the input section 14a of the high output operation is selected, the interior light 7 is turned off, and the indicator light 15a indicating the turned off state is turned on. When the input unit 14b for the normal output operation is selected, the interior lamp 7 is turned on, and the indicator lamp 15b indicating the lighting operation is turned on.

The heating of the food 1 is advanced, and when the set heating time and temperature are reached, the heating of the food 1 is terminated, and the user operates the door 1.
1, the food 1 is taken out from the cooking chamber 2, and a series of operations is completed.

Next, FIG. 4 shows a relation of power consumption at the time of heating selected by the output operation input unit 14. (A) of this figure is the power consumption at the time of the normal heating which selected the input part 14b of a normal output operation, and turned on the interior light 7,
(B) shows the selection of the input section 14a of the high output operation,
This is the power consumption when heating is performed in a state where is turned off. As is clear from FIG. 4B, the power consumption of the interior lamp 7 can be used as the power consumption of the heating unit 5 within a certain power consumption.
3. Assuming that the power consumption of the heating unit 5 is W4, the power consumption of the heating unit 5 can be increased by about (W3 / (W3 + W4)) × 100%, and the output of the heating unit 5 can be increased.

Next, it is necessary to adjust the heating time because the output differs when the input unit 14a for the high output operation is selected and when the input unit 14b for the normal output operation is selected. Similarly, it is assumed that the automatic cooking menu key 19 also affects the heating time.

As a countermeasure, the control unit 8 corrects the heating time based on the power consumption difference and the efficiency of the heating unit 5 so that the same finish is obtained regardless of which mode is selected.

With the above-described configuration, if the user wants to perform heating with high output, the user can select the input section 14a for high output operation with the output operation input section 14 so that the normal operation can be performed. Heating can be performed at a higher output, and the heating time can be shortened.

When heating the food 1 in the cooking chamber 2 while carefully observing the food 1, it is necessary to turn on the interior lamp 7, so that the output operation input unit 14 uses the input unit 1 for the normal output operation.
Select 4b.
