位置で停止させる。The heating electrode 3b at the bottom is fixed, and the heating electrode 3a at the top moves up and down, and is manually moved up and down to a position that matches the size of the frozen object 8. A voltage is applied to the upper and lower heating electrodes 3a and 3b from a high frequency power source 4. Upper heating electrode 3
a, the lower heating electrode 3b is covered with an upper insulating plate 5a and a lower insulating plate 5b, each having a low high frequency loss, to prevent the heating electrode from directly contacting the frozen object 8 or the human body. A spring 6 is installed between the upper heating electrode 3a and the upper insulating plate 5a.
, and a proximity detection device 7 are provided. Normally, an appropriate distance is provided between the upper heating electrode 3a and the upper insulating plate 5a by the spring 6, but when the upper heating electrode 3a is lowered, the upper box sickle plate 5a comes into contact with the frozen object 8. When pressure is applied and the upper brood elephant plate 5a and the upper heating electrode 3a come close to each other, the proximity detection device 7 operates and issues an alarm.The proximity detection device 7 is, for example, a microswitch with a protrusion.Shield box 2 There is an oven cavity where a heating electrode is installed and a power box where a high frequency power source 4 is installed, which are separated by a shield plate 2' except for the part through which the feeder line 4' passes. A high-frequency voltage is applied to the heating electrodes 3a and 3b to dielectrically heat the frozen object 8 placed between them. 3a and 3b come into contact, the motor current of the gear motor increases, and the apparatus includes a proximity detection device 10 that detects the contact, and an alarm device 11 that operates in accordance with the output signal and emits sound or light. Now, when the frozen object 8 is to be thawed, the frozen object 8 is placed between the heating electrodes 3as3b and the L gear motor 9 is energized to move the heating electrode 3a downward and stop it at an appropriate position.

ができるものである。However, if the gear motor 9 is not stopped by mistake, the heating electrode 3a will come into contact with the frozen object 8, and a load higher than normal will be applied to the gear motor 9, increasing the motor current and causing the output signal of the proximity detection device 10 to change. In response, the alarm device 11 operates and issues an alarm. As a result, the user can immediately remove the gear motor 9.
Since the heating electrode 3a can be stopped, the vertical mechanism 9 of the heating electrode 3a can be prevented from being destroyed. Effects of the Invention As is clear from the above embodiments, according to the present invention, the user is notified that the heating electrode has come into contact with the frozen object in the manual or automatic up-and-down mechanism, and the distance between the heating electrode and the frozen object is In addition to preventing heating efficiency from decreasing if they are too far apart,
This can prevent the heating electrode or the vertical mechanism from being destroyed due to stress being applied to the electrode vertical mechanism due to the heating electrode coming into contact with the frozen object.
