Description

DETAILED DESCRIPTION OF THE INVENTION In the past, defrosting machines were mainly used for commercial purposes, and were therefore large-sized and had a single function for defrosting. The present invention improves economic efficiency by incorporating a heater into a defrosting machine to provide an oven cooking function, and by using the heater as an electrode during defrosting.

FIG. 1 shows an embodiment of the present invention. 1 is for example
60Hz, 100V commercial power supply, 2 is power switch, 3
- 5 is a switch for switching the function between defrosting and oven cooking; 6 is a high frequency oscillation unit; 7 is a commonly used heater such as a sheathed heater, which also functions as a defrosting electrode during defrosting;
Reference numeral 8 denotes an electrode facing the heater electrode 7. The food to be cooked is then inserted between the heater/electrode 7 and the electrode 8 in the thawing chamber.

FIG. 2 shows an example of the basic configuration of an embodiment of the present invention. 7 is the heater/electrode, 8 is the electrode, 9 is semi-fixed support means for supporting the heater/electrode 7, 10, 1
1 is a fixed support means for supporting the electrode 8, and 12 is a shield case, which constitutes a thawing chamber. The food to be cooked and the heater/electrode 7 are connected by the semi-fixed support means 9.
The structure is such that the gap between the two can be adjusted to suit either thawing or oven cooking.

In Figure 1, when defrosting, open switches 3 and 4, close switch 5, and turn on power switch 2.
When closed, the high frequency oscillator 6 generates several MHz, several
KV _P - The high frequency voltage of _P is used as a heater and electrode 7, electrode 8
The food to be thawed inserted in the middle is thawed. Further, when cooking in the oven, switches 3 and 4 are closed, switch 5 is opened at the same time, and power switch 2 is closed, so that current flows through heater-cum-electrode 7 to heat the food and cook the food.

In this example, one of the thawing electrodes is used as a heater, but both electrodes can also be used as a heater.
In this case, food can be heated from both the top and bottom directions during oven cooking. In addition, by combining with a suitable timer, it is also possible to automatically cook the defrosted food in the oven after defrosting it.

As described above, the present invention can provide a defrosting machine with various additional functions by providing an oven cooking function, and can contribute to the popularization of defrosting machines in general households. Further, according to the present invention, this can be realized with an economical component configuration, and very excellent effects are achieved.
