Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-frequency heating device equipped with a temperature probe that detects the temperature of an object to be heated.

When cooking an object to be heated, there are two methods: setting a timer using a timed oscillation circuit and cooking for a predetermined period of time, and inserting a temperature probe into the object to detect the temperature of the object and bringing it to the specified temperature. There is a method of omitting the oscillation circuit when the oscillation circuit is reached.

Therefore, in the case of oscillation due to timer expiration, the temperature probe is removed and taken out from the high-frequency heating chamber and stored, but since there is no place to store this temperature probe, it may be lost or unsanitary when reused.

Also, if you forget to leave the temperature probe in the high-frequency heating chamber,
When the oscillation is performed by the timer, a spark is generated at the part that contacts the inner wall, and the thermistor of the temperature probe is damaged within a few seconds, making it necessary to repurchase the expensive temperature probe. This invention was made in view of the above circumstances, and its purpose is to provide a high-frequency heating device that can prevent the temperature probe from losing its powder and also prevent the temperature probe from being damaged due to misuse. This is what we are trying to provide.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

Reference numeral 1 in FIGS. 1 and 2 is a main body of a high-frequency heating device, and a high-frequency heating chamber 2 equipped with a high-frequency oscillator (not shown) is provided inside the main body. Furthermore, a door body 3 and an operation panel 4 for opening and closing the entrance of the high-frequency heating chamber 2 are provided at the front of the main body 1. Furthermore, a storage chamber 5 consisting of a recessed portion is provided in the upper part of the main body 1 located on the front side, so that the temperature probe 6 can be stored at times of inconvenience. A jack 7 for a temperature probe 6 is mounted on the side wall of this storage chamber 5.
A through hole 8 is bored into which the sensor is inserted, and a detection switch 9 made of a microswitch is installed near the through hole 8. The detection switch 9 is electrically connected to the timed oscillation circuit 10, and when the temperature probe 6 is stored in the storage chamber 5 and the jack 7 is inserted into the through hole 8, the detection switch 9 turns ○N and sets the timer. When the oscillation circuit 10 is closed and the jack 7 of the temperature probe 6 is removed from the through hole 8, the oscillation circuit 10 is turned OFF and the circuit 10 is opened. Further, an opening/closing lid 12 is hinged to the upper entrance portion 11 of the storage chamber 5. Therefore, when the object to be heated is heated by the timer time-limited oscillation, the temperature probe 6 is not needed, so the temperature probe 6 is stored in the storage chamber 5.

When the jack 7 of the temperature probe 6 is inserted into the through hole 8, the detection switch 9 is turned on by the jack 7.
The timed oscillation circuit 10 becomes a closed circuit. That is, when the temperature probe 6 is not used, the temperature probe 6 is stored in the storage chamber 5 and the time-limited oscillation circuit 10 is not closed unless the jack 7 is inserted into the through hole 8. It becomes impossible to cause the temperature probe 6 to oscillate if it is left inside the temperature probe 2, and damage and loss of the temperature probe 6 can be prevented. In addition, when cooking using the temperature probe 6, the temperature probe 6 is used.

. When the jack 7 of the tube 6 is removed from the through hole 8, the detection switch 9 is turned off and the timed oscillation circuit 10 is opened.
Therefore, by taking out the temperature probe 6 from the storage chamber 5, the time-limited oscillation circuit 10 can be automatically opened. The temperature of the heated object can be detected by inserting it into the socket. In addition,
In the above embodiment, a through hole 8 and a detection switch 9 are provided in the side wall of the storage chamber 5, and a jack 7 of the temperature probe 6 is provided.
Although the detection switch 9 is turned on when the through hole 8 is inserted, the present invention is not limited to the above embodiment, and may be configured as shown in FIG. 3.

That is, a hook 14 for the temperature probe 6 is provided on the back surface of the opening/closing lid 13, and a spring 15 is provided to always bias the temperature probe 6 in the opening direction. A detection switch 16 that is turned on when the opening/closing lid 13 is closed is provided in the storage chamber 6 facing the back side of the opening/closing lid 13. With this configuration, when the temperature probe 6 is in use, the opening/closing lid 13 is in an open state, and when it is inconvenient, the opening/closing lid 13 is closed, thereby preventing damage or loss of the temperature probe 6, as in the above embodiment. It can be naturally prevented.

As explained above, this invention includes a storage chamber for storing a temperature probe in the main body, and a detection switch that closes a timed oscillation circuit when the temperature probe is stored in the storage chamber and opens the circuit when the temperature probe is removed. This allows the temperature probe to be stored cleanly and to prevent it from being lost.

Moreover, since it is impossible to oscillate the temperature probe while leaving it in the high-frequency heating chamber, it is possible to prevent damage to the temperature probe.
