Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device that uses steam, electric heat, and high frequency waves to easily perform various types of cooking, and is particularly designed to improve its usability.

The present invention will be described below based on the illustrated embodiments. Reference numeral 1 denotes a cooking device main body, which includes an outer case 2 and a heating box 4 in which a heating chamber 3 is formed.

Reference numeral 5 denotes a turntable disposed at the bottom of the heating chamber 3, which is rotated once by a turntable motor 6 disposed at the bottom of the main body 1.
Driven.

7 is a magnetron that supplies high frequency waves into the heating chamber 3 via the waveguide 3; 9 is a high frequency supply lamp that illuminates the inside of the heating chamber 3 via a side wall L11;
12 is a water storage tank, and 13 is a vaporization chamber with an electric heater 14 buried in the bottom, which communicates with the water storage tank 12 through a water receiver 15 and a pipe 16, so that water is always kept at a constant water level from the water storage tank 12. It is now being supplied.

17 is a steam supply pipe i8, and 19 is an electric heater provided at the upper and lower parts of the heating chamber 3, each having a heat generating capacity of about 1 kW.

Reference numerals 20 and 21 designate exhaust holes provided on the ceiling surface of the heating chamber 3 and the upper surface of the outer case 2, and 22 represents an exhaust duct, which detects the humidity of the humidity controller 41, which will be described later, and controls the energization of the electric heaters 1B and 19. 23 is housed therein.

Next, to explain the circuit configuration, 24 is a power supply, 25 is a power switch, and 26 is a door (not shown) that covers the heating chamber 3.
This is a door switch that opens and closes in response to the opening and closing of the door.When the door is opened, it is switched as shown by the broken line in the figure.

Reference numeral 27 designates a high-frequency oscillation circuit 28 consisting of a magnetron, a high-voltage transformer, a capacitor (all not shown), etc., and a timer switch with an adjustable operating time that sets the energization time for the electric heaters 14, 19, and 20. have.

30, 35, and 39 are cooking selector switches that change the heating source according to cooking, 31 is a fan motor that blows cooling air to the magnetron 7, and 32.36 is a timer switch 27.
This is an alternating switch that repeats the switching operation at predetermined time intervals in conjunction with this timer switch during operation, and in this embodiment, it is set to about 5 seconds for the aye contact side and 45 seconds for the b and d contact sides. .

Reference numerals 33, 34, 37, and 38 are combination switches that are switched when heating means are used in combination. For example, if the cooking selector switch 30, 35 is closed and the switch 3a is closed, the above-mentioned alternate switching operation of the switch 32 is performed. Thus, one cycle of high-frequency heating for 5 seconds and heating by the electric heater 14 for 45 seconds is repeated.

40 is a heater changeover switch for switching the heaters 18 and 19 in the heating chamber 3, and 41 is a humidity controller.

In the above configuration, the operation will be explained next. First, when performing high frequency heating, steam heating, and electric heating individually, the combination switches 33, 34, 3
7, 38, and cooking selector switch 30, 35, 39.
(for example, by closing 39), setting the temperature with the humidity controller 40, and setting the timer switch 27, the timer contact 29 is closed, and the door (not shown) is closed. When the power switch 25 is closed, the heating chamber 3 is heated to the set temperature by the heaters 18 and 19.

Similarly, if only the cooking selector switch 35 is closed, a small amount of water stored in the vaporizing chamber 13 is rapidly vaporized and steam heating is performed.

Then, when the set time of the timer switch 27 has elapsed, the contact 29 opens.

Next, when using a combination of high frequency, steam, and electric heat heating means, use the cooking selector switch 30.35.39.
For example, when using a combination of high-frequency heating and steam heating, the cooking selector switch 30.35 is closed, the combination switch 33.34 is opened, the switch 38 is closed, and then the above-mentioned If the operation is performed in the same manner as when using only one heating means, the switch 32 repeatedly performs high frequency heating for 5 seconds and steam heating for 45 seconds during the time set by the timer switch 27.

Similarly, the switching operation ff of the cooking changeover switches 30, 35, 39 and the combination switches 33, 34, 37, 38 [Thus, it is possible to alternately drive any two of the heating means of high frequency, steam, and electric heat in combination.

Furthermore, by operating the same switch, three of the three heating means can be heated.
It is also possible to drive one or any two at the same time.

Here, the switching time and the ratio for repeating the switching operation at predetermined time intervals in conjunction with the timer switch 27 can be made variable using a switching circuit using a thyristor, a timing element, etc. If a selection device is provided for selecting the ingredients and their distribution ratios, the user can freely select and set them depending on the type of cooking.

As described above, according to the present invention, each of the three heating means can be driven independently, and any two can be selected and driven alternately, thereby significantly expanding the cooking range and improving usability. Good cooking equipment available.
