Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a door (hereinafter referred to as a pull-out door) that has a structure that can be opened and closed in a front closing part of an electric oven, high-frequency heating device, etc. while maintaining a state substantially parallel to the plane of the entrance of the heating chamber.
The purpose is to provide an easy-to-use cooker that can cook food well and has a pull-out door that can be smoothly opened and closed.

Conventionally, there is no so-called pull-out door type high-frequency heating device equipped with a magnetically driven turntable, but this magnetically driven turntable has the following drawbacks.

■ The coupling force of magnets deteriorates in inverse proportion to the square of the distance between the magnets, so the distance between the magnets must be maintained with high precision.

■ With the pull-out door fully pulled out, as shown in Figures 1a and b, one side is supported by the support part 12, and the other side is supported by the support roller 15 that is slidably connected to the bottom of the oven. If a so-called double-sided pull-out door is used, the depth of the heating chamber 2 will be larger than necessary in order for the saucer 13 to be easily pulled out, and on the other hand, the saucer 13 cannot be enlarged to its full size, which is quite inconvenient. It's the economy.

Therefore, as shown in FIG. 2, when the drawer door is fully pulled out, a so-called cantilever type door that supports the saucer 13, heated object 14, etc. with only the support part 12 is considered, but a magnetically driven type In the electric oven high-frequency heating device having a turntable, as described above, there is a problem in that the distance between the magnets and the positional relationship between the magnets must be highly accurate. In addition, in the case of the so-called cantilever door system, there is a problem in terms of strength, and when a heavy object to be heated is placed on it, as shown by the arrow ↓ in Fig. 2, the (saucer) support 11 will drop, making it difficult to close the door next time. , there was a risk that it would not close.

The present invention solves the above problems, and will be described based on an embodiment in which the present invention is applied to a high-frequency heating device shown in FIGS. 3a and 3b.

A heating chamber 2 is provided in the main body 1, and high frequency electromagnetic waves generated by a magnetron 3 are guided into the heating chamber 2 through a waveguide 4 and supplied from a power feed port 5. On the other hand, a movable rail 7 is fixed to the lower part of a door 6 provided at the front entrance of the heating chamber so as to be openable and closable, and this movable rail with a movable roller 9 runs on a fixed roller 8 fixed to a fixed rail 16. 7 moves back and forth together with the door 6, and the door 6 is opened and closed. Also door-6
A support portion 12 that supports a support base 11 that supports a rotary teaching platform 10 is fixed to the surface facing the inside of the heating chamber 2 . On the other hand, two support rollers 15 are supported at one end of the support base 11, and the support base 11 is supported at the front and rear by these support rollers 5 and the support portion 12. Therefore, when the door 6 is closed, the support stand 11 does not support the heated object 14 or the saucer 1.
3, it will not curve downward. In addition, when the door is fully opened, the other portion of the support base 11 that is not supported by the support portion 12 inevitably falls due to the load. Therefore, the front entrance part of the fixed rail 16 is made larger than the height t of the rail as shown in FIGS. 3a and 3b, and the door is slightly inclined as shown in FIG. 3b. The other portion that is not supported by the support portion 12 is located above the bottom surface of the heating chamber. For this reason, even if a heavy load is applied to the door 6, the vertical position of the support roller 15, which is rotatably supported on the support stand 11, is located above the bottom surface near the bottom surface of the front entrance of the heating chamber. This allows the support roller to open and close smoothly without hitting the bottom of the entrance at the front of the heating chamber. Next, the structure for rotating the rotating platform 10 will be described.

That is, a plurality of magnets 18 are mounted under the bottom surface of the heating chamber 2, and a rotating body 17 is rotatably supported around a shaft 19. Further, a roller 20 is attached to this rotary body 17 so that the magnet 18 is placed as close as possible to the bottom plate of the heating chamber 2 so that it rotates smoothly, and a belt groove 21 is provided on the circumference of this rotary body 17. When the motor 22 is formed and the motor 22 rotates, the rotating body 17 to which the magnet 18 is attached rotates at a constant reduction ratio. On the other hand, a magnet 24 is mounted on the rotary battle pupil stand 10 at a position facing the magnet 18, and the bottom plate of the four heating chambers 2 and the mounting bracket 25 of the magnet 24 are made of a non-magnetic material so as not to weaken the magnetic force. Therefore, the magnets 18 and 24 are attracted to each other, and as a result, the rotary calendar table 10 rotates as the rotating body 17 rotates. According to the above configuration, since the object to be heated 14 rotates together with the rotating counterfeit table 10, even if the electric field distribution (heat distribution in the case of an oven) in the heating chamber 2 becomes uneven, the object to be heated 14 No uneven heating occurs. In addition, when the door 6 is opened, the object to be heated 14 comes out of the heating chamber 2 together with the rotary copy stand 10, so there is no need to take the trouble of inserting your hand into the heating chamber 2 to take out the object to be heated. It becomes extremely easy to use. As described above, according to the present invention, the following effects can be expected.

■ When the door is opened and closed, the rotary stacking table comes out of the heating chamber with the object to be heated in a layered state, so there is no need to go out of your way to reach into the heating chamber to take out the object to be heated. Moreover, as a result, there is no need to turn the heated object upside down when taking it out, making it extremely convenient to use.

■ Since the object to be heated is rotated by the rotating counterfeit table, there will be no uneven heating of the object even if the electric field distribution or thermal atmosphere (in the case of electrical open circuit) in the heating chamber is uneven.

■ When the drawer door is closed, the support roller 15
Since the support portion 12 supports the saucer 13, the object to be heated 14, etc., there is sufficient holding strength even when heavy objects are placed thereon.

In addition, since the distance between the magnets in the vertical direction is regulated by the support part 12 and the support roller 15, even if a heavy object is placed on the tray, it will not come too close to the bottom surface of the heating chamber and the mounting bracket 25 of the magnet 24, making it stable. You can get the rotation of the rotating battle layer platform. - When opening the drawer door, the movable rail 7 with the movable rollers 9 moves together with the door 6 on the fixed roller 8 fixed to the fixed rail 16, so it can be opened smoothly.

In addition, the door can be abbreviated to the wing, and the heavy object can be placed in the saucer 13.
Even when the door is placed on top, the vicinity of the front closing part of the fixed rail 16 is tilted, so that the door 6 is slightly tilted and the other part of the support base 11 that is not supported by the support part 12 is heated. Since it is configured to be located above the bottom of the chamber, the door can be opened and closed smoothly without the support roller 15 etc. hitting the front opening of the heating chamber and making it impossible to close the door.
