Abstract

PURPOSE:To contrive construction of equipment by components of small capacities, by providing a preset function of executing stage heating of single heating of high-frequency or electric heating and of combination heating thereof and by preventing simultaneous execution of both the high-frequency heating and the electric heating in the combination heating thereof. CONSTITUTION:In high-frequency heating equipment, a heater 4 is provided in the upper part 3a of a heating chamber 3 and a rotary support table 7 rotated by a motor 8 is disposed in the lower part of the bottom part 3c of the heating chamber 3. Besides, a magnetron 5 is provided at the lateral part 3b of the heating chamber 3 through a waveguide 6 interposed. High-frequency heating is executed in a first stage and combination heating of the high-frequency heating and electric heating enabling execution of heating from both the inside and the surface is executed in a second stage, while the electric heating forming a scorched part of the surface is executed in a third stage, through the intermediary of a control circuit. A construction is so made in this case that a heating operation is regulated so that the high-frequency heating and the electric heating may not be executed simultaneously in the combination heating.

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 device with an electric heating device.

[0002]

2. Description of the Related Art Conventionally, in a high-frequency heating device with an electric heating device, a program is preset so that optimum heating can be obtained by a control unit only by the user inputting the weight of food, and at the same time, high-frequency heating and electric heating are performed. However, there are problems that the input current becomes large and the power consumption becomes large because both of them are heated at the same time.

A conventional example will be described below with reference to FIGS. As the heating pattern, there are high-frequency heating by the magnetron of FIG. 5a, electric heating heating of FIG. 5b and combination heating of high-frequency heating and electric heating as shown in FIG. 5c. Optimal if the food weight is input as shown in FIG. Programs are preset for each menu to get heating. This program makes heavy use of combination heating as shown in Fig. 5c to save time.
In addition, it is common to use a plurality of heating patterns in many cases in order to improve the quality.

[0004]

However, in this heating program, since the high frequency heating and the electrothermal heating are performed at the same time, the input current becomes large, the power consumption becomes large, and a component having a large capacity must be used. There is also a problem that there is a complaint that the breaker is cut off due to a large current depending on the household of the user and that the energy saving is sacrificed for the time saving.

Therefore, it is an object of the present invention to provide a high-frequency heating apparatus with an electric heating device equipped with a control unit having a plurality of heating pattern programs which can save time and achieve energy saving in an automatic program.

[0006]

In order to achieve the above object, the present invention controls a heating chamber, a high frequency generator and an electric heating device coupled to the heating chamber, the high frequency generator and the electric heating device. With a control unit to perform, the control unit has a preset function to perform high frequency heating or electric heating alone heating that can obtain optimum heating only by inputting the food weight for each type of cooking, and stage heating of combination heating. In addition, in the combination heating of the high frequency heating and the electric heating, both heatings were not performed at the same time.

[0007]

The high-frequency heating apparatus with an electric heating device of the present invention is provided with a heating pattern capable of achieving a plurality of energy saving in an automatic cooking program, so that the input current and power consumption are suppressed and a large capacity component is not used. You can achieve time-saving cooking and prevent energy saving from being sacrificed.

Further, by suppressing the input current, it is not necessary to use a component having a large capacity, so that it can be provided to the user at a low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric heating device according to an embodiment of the present invention will be described with reference to the drawings in a high frequency heating device.

As shown in FIG. 3, a general high-frequency heating device with an electric heating device is provided with a control unit 1 and a door 2 for containing food. FIG. 4 is a sectional view of FIG. A heater 4 is provided on an upper portion 3a of the heating chamber 3, and a bottom portion 3c of the heating chamber 3 is provided.
A motor 8 for supporting and rotating the rotation support base 7 in the heating chamber 3 is attached to the lower side, and an object-to-be-heated mount 10 for mounting an object-to-be-heated 9 is provided on the rotation support base. There is.

A waveguide 6 is provided on the side surface 3b of the heating chamber 3.
A magnetron 5 which is a high frequency generating means is coupled to the object 9 to be heated by radiation and convection heating by the magnetron 5 or the heater 4.

As shown in FIG. 2, the heating pattern is shown in FIG.
The high frequency heating of a, the electric heating of FIG. 2b, and the combination heating in which the high frequency heating and the electric heating of FIG. 2c are alternately heated are provided. And the program is preset for each menu so that the optimum heating can be obtained by inputting the food weight.

As shown in FIG. 1, by combining these heating patterns, the first stage is subjected to high-frequency heating capable of heating from the inside, and the second stage is subjected to combination heating capable of heating from the inside and the surface. In the third stage, which is the final stage, electric heating is performed so that the surface is marked.

For example, if a chicken is selected with the automatic cooking key 11 and a weight of 1 kg is input with the weight setting key and the start key 13 is pressed, the first stage high frequency heating is 22 seconds on, 0 seconds of of.
f is 9 minutes 10 seconds, second stage high frequency heating 18 seconds on,
Alternate combination heating of 15 seconds off, electrothermal heating 15 seconds on, 18 seconds off is performed for 9 minutes 10 seconds, third stage electrothermal heating 33 seconds on, 0 seconds off is performed for 8 minutes.

In this embodiment, since the high frequency heating and the electrothermal heating are not simultaneously performed, the input current does not increase. In addition, by providing three stages of heating patterns that make the best use of their respective characteristics, time-saving cooking and energy-saving cooking have become possible.

For example, as shown in (Table 1), when cooking 1 kg of chicken, the cooking time of 24 minutes and 20 seconds is 73% in the conventional example.
Although it consumed 4 Wh, in this embodiment, the cooking time is 24 minutes 2
Power consumption is 540 Wh and 26.4 in exactly the same time as 0 seconds.
It has succeeded in reducing%.

In the present embodiment, the case where the high frequency heating is performed in the first stage, the combination heating is performed in the second stage, and the electrothermal heating is performed in the third stage has been described, but the order of each heating is not limited to this order. Instead, it may be heated in a heating order suitable for the type of cooking.
