Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite high-frequency heating device with a steam generator, and particularly relates to a switching method when heater heating is used in conjunction with the steam generator as an auxiliary heating means when necessary. Recently, in addition to high frequency heaters,
Commonly used are so-called composite high-frequency heating devices that use multiple heating means in one oven space, such as ovens and grills using electric heating devices, steaming dishes using steam generators, and complex cooking in which different heating means are operated in conjunction with each other. It is becoming a target.
Among them, there is a method to prevent food from drying by using steam as an auxiliary during high frequency operation,
Various types of combined heating have been considered and some have been commercialized, such as using an electric heating device to supplement steam generation.

The present invention aims to provide a switching device with a simple configuration and easy operation when an electric heating device is used as auxiliary heating when steam is generated in such complex heating.

This will be explained below with reference to the drawings. FIG. 1 is a schematic diagram of the main body of the embodiment of the present invention, where 1 is the main body, 2 is the door,
3 is a water supply tank for the steam generator, 4 is a water level gauge, 5 is a cooking selection switch button,
The built-in switch switches the circuit. Reference numeral 6 indicates a timer, and 7 indicates an internal temperature regulator section, which in the present invention is also used as a switching means for steam cooking, as will be described later. 8 is a cooking start button, and 9 is a scale. 2 to 4 are a simplified configuration diagram and a circuit diagram of an embodiment of the present invention.

11 is a temperature variable element, 13 is a main shaft for operation, 7
Reference numeral 14 is the aforementioned operating knob, and 14 is a cam for operating the changeover switch 12 provided on the main shaft 13. The switch is operated by operating the switch lever 15 with the cam. This is set on the circuit as shown in FIG. That is, when the adjustment selection switch knob 5 is set to steam, for example, the contact 16 of the built-in switch is set to the a side, the contact 19 is set to the a side, and the steam heater is set to the a side.
_H3 works. When the knob 7 is set to the strong steam side of the steam scale display 10, the aforementioned changeover switch 12 is operated by the cam 13 and turned ON as shown in the contact point 18 in Fig. 4, and the switch 12 is connected in parallel with the steam heater _H3 . Oven heater _H2 is configured in a circuit and operates simultaneously. However, since it is not necessary for steam cooking to reach the same high temperature as when cooking in an oven using steam heating (heater heating is only an auxiliary heating means), a diode such as 20 is used to prevent the temperature from rising above a certain level. It may be necessary to take measures such as half-wave rectification to reduce the heater output. It goes without saying that this method is not limited to the use of diodes, and that a peak cut thermostat may also be used. As mentioned above, as shown in FIG. 2, a scale for regulating the internal temperature and a display 10 for steam are written around the knob 7, and the switch 12 is switched from the operating point of the changeover switch 12 as a boundary.
For example, the ON side is displayed as "steam strong" and the OFF side is displayed as "steam weak". In other words, strong steam is used in combination with heater heating, and is used for cooking with relatively high temperature steam, such as steamed buns. As mentioned above,
By combining the internal temperature control knob with the steam strength/weakness selector switch, it is possible to simplify the operation section of a complex cooker, which tends to be complicated, and the configuration is also extremely simple, making it possible to provide the product at a low cost. .
