Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high-frequency heating apparatus, and more particularly to a structure for restricting the movement of a conventional tray for heating objects, which is freely disposed inside a heating chamber of the high-frequency heating apparatus.

Conventional technology In a conventional high-frequency heating device equipped with a so-called turntable, which rotates the food to be cooked to eliminate uneven heating during cooking, the rotational driving force of the motor is transmitted to the rotary table using the following configuration. are doing.

In other words, the rotational driving force of the motor is transmitted to the rotary plying table through the speed reduction mechanism and the rotary shaft that is rotatably supported by penetrating the bottom surface of the heating chamber.
Further, the rotation shaft and the rotary stacking table are connected by attaching the locking hole of the rotary stacking table to the locking portion of the rotating shaft. Therefore, when the heating chamber is contaminated with food particles, etc., and the rotating platform is removed from the heating chamber to clean it, the rotating platform is lifted upward to disconnect it from the rotating shaft, and then The operation of taking it out from the heating chamber is cumbersome, and it is especially difficult to take it out when the rotating bed bed is large. Furthermore, even when cleaning the inside of the heating chamber, the rotating shaft protrudes from the inner bottom of the heating chamber, and furthermore, a support body that supports the periphery of the rotating counterfeit table is arranged around it, making it easy to clean. Furthermore, even if you clean it, it will not be possible to remove food debris that has gotten into the rotating shaft or the part of the support where the coffin is installed, which will reduce the commercial value of the high-frequency heating device as a clean cooker. It had become. Therefore, in order to eliminate these drawbacks, a high-frequency heating device has recently been developed that uses a magnetic coupling means in the rotating mechanism that transmits the rotational driving force of the motor to the rotary war machine. The structure using is as follows.

That is, a rotating body is provided on the outside bottom of the heating chamber, and is rotatable around a support shaft and has a plurality of magnets arranged around it. Further, a rotary lectern with a magnet magnetically coupled to the above-mentioned magnet is provided on the bottom of the heating chamber, and this rotary lectern is supported by a support having wheels and is housed in a rotatable manner. In this way, there is no shield on the bottom of the heating chamber, and the rotating lectern can be easily cleaned by taking it out from the heating chamber, and the circular saucer on the rotating lectern is also almost horizontal. You can easily slide it in and out. Problems to be Solved by the Invention However, when the saucer is taken in and taken out almost horizontally, the bottom surface of the heating chamber may be damaged when the tray is put in and taken out.
This is particularly a serious problem in high-frequency heating devices whose heating chambers are coated.

In addition, by making the saucer super movable almost horizontally, in high-frequency heating devices with a so-called engine door, when pulling out the saucer after cooking, there is a high possibility that the saucer may be pulled out too far and the food may be overturned. There was a risk of burns when cooking hot food.

Furthermore, since the saucer was made to be able to move freely approximately horizontally, when the saucer was put into the heating chamber, it was forced into the heating chamber with too much force, and as a result, the saucer could hit the rear wall of the heating chamber and be damaged. .

The present invention prevents the saucer and the food placed on it from being overturned when pulling out the saucer for directly placing the heated object from the heating chamber, or damaging the saucer when putting the saucer into the heating chamber. The purpose is to prevent Means for Solving the Problems The present invention provides a rotary tray for rotating the trays in a heating chamber, and restricts the horizontal movement of the trays on the rotary tray within a certain range. On the other hand, when rotating, a stopper is provided to allow normal rotation.

Function: By forming this stopper, it is safe and easy to use because it prevents the saucer from being pulled out too far and dropping and breaking, or overturning the food.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, 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 food A,
A microwave generator 3 for supplying microwaves is built into the heating chamber 2.

In addition, 4 in FIG. 2 is a door attached to the front entrance of the heating chamber 2 so as to be openable and closable, and this door 4 includes a screen 5 and a handle 6 for viewing the heating state of the food A in the heating chamber 2.
is installed. 7 is the high frequency heating device main body 1
The operation panel 7 is arranged on the front side, and the knobs of the control section for controlling the microwave generator 3 are arranged on the operation panel 7.

Furthermore, reference numeral 8 in FIGS. 1 and 2 is a rotary battle stage which is detachably and rotatably disposed in a recess 9 provided on the inner bottom surface of the heating chamber 2. On the back circumference,
An annular support body 1 that rotatably supports this rotary calendar table 8
A groove 11 in which a wheel 10b of 0 is disposed is formed. Further, on this back surface portion, a magnet 14 is disposed, which is magnetically shielded by a shield plate 12 such as an iron plate, and is housed and held in a storage container 13. Reference numeral 15 denotes a stopper projecting from the side surface of the storage container 13 toward the groove 11, and the support body 10 is held by the stopper 15.

On the other hand, the support member 1 has a ring body 10a and the wheel 1 is rotatably supported at key points of the ring body 10a and is removable.
0b, and the load of the rotating Hagi calendar table 8 and the food A to be cooked on the rotary plying table 8 is applied only to this wheel 10b because the rolling friction of the wheel 10b is used. act. Note that the groove 11 is formed by drawing upward the peripheral edge of the upper plate of the rotary battle stand 8, and the wheels 10b of the support body 10 are formed on the vertical wall 11a forming the groove 11. Prevents it from coming off. Reference numeral 16 denotes a rotating body that is rotatably supported in a floating state on a support shaft 17 that is fixed by welding to approximately the center of the outer bottom wall of the recess 9 of the heating chamber 2. A magnet 18 that is magnetically coupled to a magnet 14 attached to the base 8 by an attractive force, and wheels 19 that support the periphery of the rotating body 16 are provided.

This motor 2 is a motor that rotates the rotating body 16.
A pulley 21 is fixed to the rotating shaft of the rotor 0, and the pulley 21 and the rotating body 16 are connected by a belt 22 so that power can be transmitted.

Note that 23 is a stirrer fan that receives microwaves supplied from the microwave generator 3, and 24 is a partition plate that makes the stirrer fan 23 invisible from the outside. In the above configuration, first, the rotation of the rotating calendar table 8 will be described.

By rotationally driving the motor 20, its rotational driving force is transmitted to the rotating body 16 via the belt 22, thereby causing the rotating body 16 to rotate around the support shaft 17. As the rotating body 16 rotates, the magnet 18 disposed on the rotating body 16 also rotates, and thereby the magnet 14 that is magnetically coupled to the magnet 18 by attraction force also rotates. That is, the rotary calendar table 8 is driven to rotate, and at the same time, the saucer 25 on the rotary battle table 8 also rotates. Now, the configuration that is the gist of the present invention will be explained.

That is, in the present invention, as shown in FIG. 2, a stopper 26 is provided within the heating chamber 2.

This stopper 26 is made of polypropylene made of a low-loss dielectric material such as polysulfon, and this stopper 26 serves as a rail when the saucer 25 is moved in and out of the heating chamber 2 approximately horizontally, and when the saucer 25 is pulled out. The role of preventing saucer 25 and food A from being replaced due to overflow, and saucer 2
5 is put into the heating chamber 2 with great force and hits the rear wall of the heating chamber 2, thereby preventing damage to the saucer 25 or damage to the rear wall. The specific configuration will be described below based on FIGS. 3 to 5.

In FIG. 3, the width of the heating chamber 2 is W, the depth is D, and the outer diameter of the saucer 25 (in this case, the outer diameter is the diameter of the part that supports the stopper 26 when regulating the saucer 25 in the front and back direction. This is not necessarily the maximum diameter.

) is 2R. When the center of the saucer 25 is located close to the point ○ shown in FIG. 3, it comes into contact with the rotating calendar table 8 and becomes rotatable. Here, FIG. 5 shows a sectional view taken along the line A-A'. In this state, since it does not come into contact with the stopper 26, the rotation of the saucer 25 is not restricted by the stopper 26 at all. Further, in this state, the tray 25 can be taken out from the heating chamber 2 by lifting it upward. Even if the tray 25 is pulled out almost horizontally, the center of the tray 25 moves from point ○ to point ○' as shown by the dashed line ΔD' and comes into contact with the hole at the end of the stopper 26, and cannot be pulled out any further. Can not.

Therefore, the saucer 25 is not pulled out too much and the saucer 25 and the food A are not turned over, making it safe and very convenient to use. FIG. 4 is a sectional view taken along the line B-B', and the inside of the flange 25a of the saucer 25 (Z-B) has the following relationship. Z2-ZI>Z2-ZI In this case, the dimension of ΔD' is determined by the following equation (1) in consideration of the above-mentioned safety and usability.

△D'=Back-Y ‐‐‐‐‐‐‐‐‐‐‐‐‐(1)
Also, in order to make △D' into the equation (1), the stopper 26
The average protruding size of the tip is expressed by the following equation (0).

Sugi = Oath/X ------------ (□) In this case, X is the following equation (m), and Y in equation (m) is as shown in equation (W). ×=ノR2−Y2. ．． ．．
・．． ．． ...(m)Y=-hot-△D ‐‐‐‐‐...‐
--- (N) Also, even if the saucer 25 is inserted almost horizontally into the rear wall after being repositioned, the center of this saucer 25 will move from point ○ to point △D'' as shown by the broken line and reach the stopper. It collides with the rear end protrusion of 26 and cannot be inserted any further.

Therefore, the saucer 25 will not be damaged by hitting the rear wall 2a of the heating chamber 2 with force.

Also, the thickness of the center portion of the stopper 26 x. is expressed as the following equation (V).

~<Fort-R ‐‐‐‐‐‐‐‐‐‐‐‐‐(V) Next, the height dimensions of the stopper 26, saucer 25, etc. are shown in Figure 4.
Explain using Figure 6.

The dimension z of the saucer 25 is determined by the stopper 2 as shown in the following formula (W).
It is smaller than the z and dimension of 6.

In other words, when the saucer 25 is pulled out, the golden part 25a of the saucer 25 is guided up to the rail part 26a of the stopper 26, and thereby the same The legs 25b of the saucer 25 are lifted up from the rotating platform 8 to break contact. In addition, the z2 dimension of the saucer 25 is determined by the stopper 2 as shown in the following (skin) formula.
It is smaller than the z2 dimension of 6.

Z<z2... ．． ．． ．．・…、． ．． (Skin) In other words, by adopting this (Skin) type dimensional relationship, the flange 25a of the saucer 25 is prevented from coming into pressure contact with the rail portion 26a, and the unpleasant metallic sound caused by the pressure contact or the noise of the saucer 25 is prevented. It has no damage etc. In addition,
If the depth dimension 2 of the tray part 26a is made as long as possible so that the tray 25 does not come into contact with the rail part 26a when the tray 25 rotates, the tray 25 will not shake when the tray 25 is taken in and out.

On the other hand, Δz and ΔZ3 of the stopper 26 may be appropriately set in consideration of design and strength.

FIG. 7 shows another embodiment of the present invention, in which a stopper 26' is provided with the seal portion 26a removed. FIG. 8 shows still another embodiment of the present invention, in which a stopper 26 and a saucer 25' are provided, with the seal 26a and flange 25a removed.

As described above, according to the present invention, there is no need to pull out the saucer too much and turn the saucer or food over again, so it is very safe and easy to use.

Further, when the saucer is inserted, the saucer does not hit the rear wall of the heating chamber with force, so the saucer is not damaged or the rear wall is not scratched.
