Description

[Detailed Description of the Invention] The present invention relates to a high-frequency heating device and aims to improve its usability.

Conventionally, as shown in FIG. 1, a heating chamber 1 is formed by a main body 2 and a door 4 which is attached to a rotary support part 3 provided on the main body so as to be openable upward.

A choke 7 is formed around the door 4 at a portion that contacts the main body 2 to prevent radio waves inside the heating chamber 1 from leaking to the outside.

The heating chamber 1 and the mounting area of the magnetron 8 are separated by a partition plate 9 made of a material with low high frequency loss.

With the above configuration, when the handle 11 provided on the door 4 is lifted, the door opens and the intersection point a between the substantially horizontal wall surface 5 of the door and the adjacent front wall surface 6 and the heating chamber opening 6 of the door are located at the rotation support provided on the main body. The liquid-containing heated objects moving as A and B, respectively (hereinafter referred to as locus A and locus B) centering on point 3, are indicated by broken line 1
0', the locus B intersects with the object to be heated 10'.

In other words, the object to be heated in this position always comes into contact with or collides with the door when the door is closed.

As a result, legal problems arise.

i The container falls over and the contents spill out.

11 Foods lose their shape, become unsightly, and are unsanitary.

iii.The container may break, which is dangerous.

iv If the front wall surface 6 of the door is made of glass, resin, etc., it will be broken or scratched.

■The door's radio wave leakage prevention structure (choke 7) and the contact surface of the door with the main body are deformed, causing radio wave leakage, which is dangerous and has an adverse effect on the human body.

V1 In order to avoid the above problem, the object to be heated needs to be placed inside the locus B, and the effective space of the heating chamber becomes narrow.

v11 It is difficult to use as it requires careful placement so that the object to be heated and the door do not come into contact with each other.

Therefore, the present invention solves the above problems and provides a door structure that is easy to use and can be used with peace of mind.One embodiment of the present invention will be described below.

In FIG. 2, the heating chamber 1 is formed by a main body 2 and a door 4 attached to the main body so as to be openable upward by a rotary support portion 3 provided on the main body.

A choke 7 is formed around the door 4 at a portion that contacts the main body 2 to prevent radio waves inside the heating chamber 1 from leaking to the outside.

The heating chamber 1 and the magnetron mounting area are separated by a partition plate 9 made of a material with low high frequency loss, and radio waves are emitted from below the heating chamber.

When the handle 11 provided on the door is lifted, the latch switch is opened by the latch mechanism, and the door is opened after the oscillation stops.
At this time, the intersection a between the substantially horizontal wall surface 5 of the door and the adjacent front wall surface 6 and the heating chamber opening 6 of the door are centered around the rotation support part 3 provided below the wall surface 5, as shown in FIG. They move as A and B, respectively, and since the trajectory B is outside or near the trajectory A, even if the object to be heated 10 is placed at the front as shown in the figure and the door is closed, the front wall 6 of the door and the opening of the pulse heating chamber Do not touch or collide with other objects.

That is, in this embodiment, since the lower end of the front wall surface 6 is inclined forward, the trajectory B passes outside the trajectory A.

Therefore, according to the present invention, the following effects can be expected.

1 You can rest assured that the container will not fall over no matter where you place it.

2. Food does not lose its shape and become unsightly, and is hygienic.

3. It is safe because the container will not break.

4 Even if the door front wall surface 6 is made of glass or resin, it is safe without being broken or damaged, and the product value does not decrease.

5. The radio wave leakage prevention structure of the door does not deform or the contact with the main body deteriorates, so the amount of radio wave leakage does not increase and is extremely safe.

6. In the present invention, the lower end of the front wall surface of the door is tilted forward, so that standing radio waves are less likely to be formed in this front wall portion, and as a result, uneven heating of the object to be heated will not occur in this portion.

As described above, the present invention provides an extremely useful high-frequency heating device that is not only easy to use and safe, but also does not cause uneven heating of the heated object, which has been a major problem with high-frequency heating devices. be.
