Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-frequency heating device, and more particularly to a high-frequency heating device equipped with a so-called turntable that rotates cooked food to eliminate uneven heating during cooking. The rotation transmission mechanism that transmits the rotational driving force of the motor to the mounting table has been improved, and the rotating mounting table, which is removably disposed on the inner bottom of the heating chamber, can be easily attached and removed, and the heating chamber can be cleaned easily. The purpose of this is to reduce the rotation noise of the rotating mounting table.

Conventionally, a rotation transmission mechanism that transmits the rotational driving force of a motor to a rotating mounting table of a high-frequency heating device equipped with a so-called turntable, which rotates the food to eliminate uneven heating during cooking, uses the rotational driving force of the motor. is transmitted to the rotary mounting table via a speed reduction mechanism and a rotary shaft rotatably supported by penetrating the bottom surface of the heating chamber, and the connection between the rotary shaft and the rotary mounting table is such that the rotary shaft is connected to the rotary mounting table. This is accomplished by fitting the locking hole of the rotary mounting table into the locking portion. Therefore, if the heating chamber of the high-frequency heating device becomes dirty with food particles, etc., the rotary mounting table must be removed from the heating chamber. It is a cumbersome operation to disconnect the rotating shaft and take it out of the heating chamber in that state, and if the rotating mounting table is large, it is very difficult to take it out. Moreover,
Even when cleaning the inside of the heating chamber, the rotating shaft protrudes from the inner bottom of the heating chamber, and the supporting body that supports the rotating mounting table is placed around it, making it difficult to clean. Even with cleaning, it is not possible to remove food debris that has gotten into the rotating shaft and the part where the support is installed, leading to a decline in the commercial value of the high-frequency heating device as a clean cooker.

The present invention eliminates the above-mentioned conventional drawbacks, and will be described below with reference to the drawings of FIGS. 1 and 2 showing one embodiment of the present invention.

In the figure, 1 is a high-frequency heating device main body, and this high-frequency heating device main body 1 includes a heating chamber 2 for storing an object to be heated and a microwave generator 3 for supplying microwaves into the heating chamber 2. There is.
A door 4 is attached to the front opening of the heating chamber 2 so as to be openable and closable, and a screen 5 and a handle 6 are attached to the door 4 for viewing the heating state of the object to be heated in the heating chamber 2. .

Reference numeral 7 denotes an operation panel disposed on the front surface of the high-frequency heating apparatus main body 1, and knobs of a control section for controlling the microwave generator 3 are disposed on the operation panel 7.

8 is a recess 9 provided on the inner bottom surface of the heating chamber 2.
A rotary mounting table is detachably and rotatably disposed on the rotary mounting table 8, and a wheel 10b that rotatably supports the rotary mounting table 8 is provided on the periphery of the back surface of the rotary mounting table 8.
and a groove 1 in which a ring body 10a that pivotally supports it is disposed.
1 is formed, and the back surface is magnetically shielded by a shield plate 12 such as an iron plate, and a magnet 14 stored and held in a storage container 13 is disposed. Reference numeral 15 denotes a stopper that protrudes from the side surface of the storage container 12 toward the groove 11;
The support body 10 is held in the groove 11 by this. The support body 10 includes a ring body 10a and this ring body 1.
A resin wheel 1 rotatably supported at key points of 0a
0b, the load is applied only to the wheel 10b, and the roller action of the wheel 10b is used to rotatably support the wheel 10b.

Reference numeral 16 denotes a rotating body that is rotatably supported in a loosely fitted manner on a support shaft 17 that is fixed to the outer bottom wall of the recess 9 of the heating chamber 2 by welding approximately in the center.
At 6, there is a magnet 14 attached to the rotary mounting table 8.
A magnet 18 that is magnetically coupled by an attractive force with the rotating body 16 and wheels 19 that support the periphery of the rotating body 16 are provided.

Reference numeral 20 denotes a motor, which rotates a fan (not shown), which cools the magnetron of the microwave generator 3 with the air blown by the fan, and which also rotates a stirrer fan 21 that stirs radio waves. It is. Further, the rotational driving force of the motor 20 is transmitted to the rotary body 16 via the deceleration mechanism 22 and the like.

Note that 23 is a partition plate for making the stirrer fan 21 invisible from the outside.

In the above configuration, by rotationally driving the motor 20, its rotational driving force is transmitted to the rotating body 16 via the deceleration mechanism, and the rotating body 16 is connected to the support shaft 1.
Rotates around 7. As the rotating body 16 rotates, the magnet 18 disposed on the rotating body 16 also rotates, thereby rotating the magnet 14 that is magnetically coupled to the magnet 18 by an attractive force. That is, the rotary mounting table 8 is rotated.

As is clear from the above description, the high-frequency heating device of the present invention includes a rotary mounting table 8 that is detachably provided on the inner bottom surface of the heating chamber 2 and is rotatable, and a rotary mounting table 8 and magnets 14, 18, etc. It consists of a rotating body 16 connected via magnetic coupling means and rotatably provided at the outer bottom of the heating chamber 2, and a drive source for driving this rotating body 16, and the rotating mounting table 8.
is rotatably supported by a resin wheel 10b that is pivotally supported by an annular body 10a, and since there is nothing planted on the inner bottom surface of the heating chamber 2, the rotary mounting table 8 is attached to the heating chamber 2. It can be easily cleaned by taking it out from inside, and the rotary mounting table 8 can be easily removed from the heating chamber 2.
When taking it out from inside, it is only necessary to pull out the rotary mounting table 8 as it is, and it can be taken out easily.

In addition, the rotary mounting table 8 is placed inside the heating chamber 2 and the ring body 10a is placed inside the heating chamber 2.
Since the heating chamber 2 and the rotary mounting table 8 are supported by a resin wheel 10b which is supported by a resin wheel 10b, sparks are not generated between the heating chamber 2 and the rotary mounting table 8, and since there is contact between the resin and the metal, frictional resistance is reduced. The small rotation is smooth and the rotation noise is very low. Furthermore, since the wheel 10b is made of resin, the inner bottom surface of the heating chamber 2 will not wear out due to friction between the inner bottom surface of the heating chamber 2 and the wheel 10b, and only the wheel 10b will wear out. It has an excellent advantage in that it only needs to be replaced with 10b.

As described above, the high-frequency heating device of the present invention is characterized in that the rotary mounting table and its support are detachable from each other, the wheels of the support are made of resin, and the rotary mounting is carried out by magnetic coupling means. Since the mounting base is configured to rotate, it is easy to attach and remove the rotating mounting base and cleaning the inside of the heating chamber, and there is no risk of sparks occurring between the rotating mounting base and the inner bottom surface of the heating chamber. In addition, the rotational sound of the rotary mounting table is very small, and the inner bottom surface of the heating chamber is not worn out.
