Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a high-frequency heating cooking device that cooks food while rotating a rotating plate on which food is placed.

(Prior art) Conventionally, in high-frequency heating cooking devices, in order to uniformly heat the food, a rotating plate on which the food is placed is provided in the cooking chamber, and instead of rotating the rotating plate with a motor, a magnetron is used. It operates to generate high frequency waves to heat and cook the food on the rotating plate.

(Problems to be Solved by the Invention) In the conventional structure described above, when the operation of the magnetron is stopped and heating cooking is completed, the rotating plate is also stopped at the same time. For this reason, for example, when heating food by placing it on the outer periphery of a rotating plate, or heating a container with a handle, depending on the stop position of the rotating plate at the end of cooking, the food may The handle of the container may be located at the back of the cooking chamber. In such a situation, in order to take out the food, the user has to insert his/her hand deep into the cooking chamber or place the food container in a position where it is easy to take out the food, which not only makes it difficult to take out the food, but also makes it difficult to take out the food. When removing the food, there was a risk of burns if the hands touched the hot side walls of the cooking chamber.

The present invention has been made in consideration of these circumstances, and therefore, its purpose is to provide a high-frequency heating cooking device that allows food to be easily taken out at any time, regardless of the stop position of the rotating plate at the end of cooking. There is something to do.

[Structure of the Invention] (Means for Solving the Problem) The high-frequency heating cooking device of the present invention includes a rotating plate on which food is placed in a heating cooking chamber, and the rotating plate is rotated by a motor while the food on the rotating plate is heated. In a device in which the motor is heated with high frequency, the motor is not connected to the motor when the heating is stopped. 'r
This configuration is equipped with operating means for operating the power.

(Function) If the food on the rotary plate is in a position where it is difficult to take out the food after cooking, the operating means is operated to energize the motor appropriately, thereby rotating the rotary plate until the food is in a position where it is easy to take out the food. After this, if the food is taken out, the food can be taken out easily.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. First, in FIG. 2 showing a perspective view of the overall appearance, reference numeral 1 denotes four compartments of a high-frequency heating cooking device, in which a heating cooking chamber 2 is provided. The front side of this heating cooking chamber 2 is opened and closed by a door 3. Further, an operation panel 4 is provided on the front left side of the outer box 1, and this operation panel 4 includes an operation knob 6 for a timer switch 5 (see FIG. 14), a button 7 for opening/closing the door 3, and an operation means. A button switch 8 is provided. On the other hand, a rotary plate 10 on which food 9 is placed is provided at the bottom of the cooking chamber 2 .

Next, the electric circuit configuration will be explained based on FIG. 1. 11

One end of the primary coil 14a of the high voltage transformer 14 is connected via the timer switch 5 and the first door switch 13,
The other end of the primary coil 14a of the high voltage transformer 14 is connected to the power line 1.2a connected to the other power supply terminal 12 via the second door switch 15. The first and second double-door switches 13.15 are turned on when the door 3 is closed, and the monitor switch 16.
is in the off state. On the other hand, a magnetron drive circuit 17 is connected to the secondary coil 14b of the high voltage transformer 14.
The DC output is applied between the anode and cathode of the magnetron 18. A fan motor 19 is provided in parallel with the primary coil 14a of the high voltage transformer 14, and the fan motor 19 and the magnetron 18 operate in the same manner.

Therefore, a button switch 8 is connected in parallel with the timer switch 5.
is provided, and this button switch 8 and rotation 111110
A relay switch 21 is provided between the drive motor 20 and the drive motor 20 . This relay switch 2] is switched to open between contacts a and b and close between contacts c and d, with contact a connected to button switch 8, contact C connected to power line lla, and contacts s and d closed. are both connected to the motor 20.

The excitation coil 22 of the relay switch 21 is connected between the two power supply inputs 11a and 12a so as to be energized when the timer switch 5 is in the on state. When the timer switch 5 is on (when the excitation coil 22 is energized), the relay switch 21 is switched to open between contacts c and d, and when the timer switch 5 is off (the excitation coil 22 is energized), the relay switch 21 is switched to open between contacts c and d. (when the power is cut off), the relay switch 21 is switched between contacts a and b to close or switch. Incidentally, a lamp 23 is connected in parallel with the motor 20,
While the motor 20 is energized, the lamp 23 is also energized to illuminate the inside of the cooking chamber 2.

Next, the operation of the above configuration will be explained. When cooking, open the door 3 and turn the food 9 111110
2, close the door 3, and operate the operation knob 6 of the timer switch 5 to turn it on.

At this time, by closing the door 3, the first and second door switches 13.15 are turned on, and the monitor switch 16 is turned on.
is turned off, and when the timer switch 5 is turned on, the high voltage transformer 14 is energized and the magnetron 18 starts operating, and the excitation coil 22 is energized and the relay switch 21 is switched to open between contacts c and d. Electricity is applied to the motor 20 and the lamp 23 through the contacts c and d.

As a result, the rotary plate 10 is rotationally driven, and the rotary plate 1
Food 9 above 0 is subjected to high frequency heating.

Then, when the set timer time has elapsed, the timer switch 5 is turned off, the operation of the magnetron 18 is stopped, and the motor 20 is cut off, so that the rotation of the rotary plate 10 is stopped. At this time, since the excitation coil 22 is also cut off, the relay switch 21 is switched to open the contacts a and b.

If the food 9 on the rotating plate 10 is in a position where it is difficult to take it out, the button switch 8 is turned on.

As a result, the motor 20 and the lamp 23 are energized through the contacts a and b of the button switch 8 and the relay switch 21, causing the rotation [10] to rotate. Therefore, the user must
If the button switch 8 is kept on until the food 9 is at a position where it can be easily taken out, and the button switch 8 is turned off when the food 9 is at a position where it is easy to take out, the rotation @10 is stopped at the position where the food 9 is easy to take out. After that, if the door 3 is opened and the food 9 is taken out from the rotary plate 10, the food 9 can be taken out easily, and there is no need to insert the hand deep inside the heating cooking chamber 2. There is no risk of getting burned by inadvertently touching a high-temperature part such as the side wall of the cooking chamber 2. Moreover,
When turning on the button switch 8 to rotate the rotary plate 10, the magnetron 18 is not energized, so the door 3
Even in the open state, the rotation 110 can be rotated by turning on the button switch 8, making it easy to use.

In addition, in the above embodiment, since the groove bottom is designed to simultaneously energize the lamp 23 when the button switch 8 is turned on and the rotary plate 10 is rotated, the illumination of the lamp 23 illuminates the inside of the heating cooking chamber 2. This has the advantage that the position of the food 9 can be easily seen. However, even if the lamp 23 is not energized when the button switch 8 is turned on, the intended purpose of the present invention can be sufficiently achieved.

[Effects of the Invention] As is clear from the above description, the present invention is provided with an operating means for turning on and off the motor for driving the rotating plate when heating is stopped. Even if the stop position is at a position where it is difficult to take out the food, the rotating plate can be rotated to a position where it is easy to take out the food by operating the operating means. There is no need to insert one's hand deep into the cooking chamber, and there is no risk of one's hand inadvertently touching a high-temperature part such as the side wall of the cooking chamber and getting burned.
