Abstract

PURPOSE:To improve the safety of the titled device equipped with a detachable slide type door, by providing the device with a limit section adapted to prevent the movement of switch upon an operating pin being deformed. CONSTITUTION:A door 2 for opening and closing a heating chamber 1 is retained by a rail section 3 elongated in the direction transvering an opening face 1a so as to be opened, closed and detached. An operating pin 22 for moving an opening/closing switch 21 equipped with a contact which is always opened for moving a high frequency oscillator 20 is provided at the top end of rail section 3. A limit section 23 is provided at an area between the switch 21 and the operating pin 22, the section 23 being adapted to prevent the operating pin 22 from passing through a slit section 23a when deformed more than a certain degree, and thereby rendering the opening/closing switch 21 unmovable. Consequently, by giving the operating pin 22 a proper strength, the operating pin 22 is deformed and prevent the switch 21 from moving when the door 2 is given an impact of magnitude sufficient enough to cause the problem of leaky radio wave.

Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to improve the safety of a high-frequency cooking device equipped with a detachable sliding door.

Conventionally, high-frequency cooking appliances have been constructed in such a way that the door cannot be easily attached or detached from the perspective of preventing radio wave leakage (the door may deform during attachment or detachment, especially if the door is dropped while it is removed). However, in the case of a door that opens and closes the opening by sliding in a direction perpendicular to the opening of the heating chamber, it is difficult to clean the inside of the heating chamber from the front with the door attached. Therefore, it was necessary to remove the door body,
This slide method has a greater risk of radio wave leakage than other methods, and is therefore difficult to put into practical use. That is, since the door body has rails for sliding, etc., it is inevitably heavy, and when the door body is removed, it is easy to accidentally drop it, and if it is dropped, the door body is also subject to a large impact.

The present invention solves the above problems and will be described below with reference to the drawings.

Figures 1 to 5 show an embodiment of the present invention, in which 1 indicates a heating chamber 1a, an opening surface of the heating chamber, and 2 a door body for opening and closing the heating chamber 1, which is fixed to the door body 2 and is fixed to the opening surface of the heating chamber 1a. Door body surface 2a facing 1a
The opening/closing unit 1 is detachably held by a rail portion 3 extending in a direction perpendicular to the opening/closing unit. At the tip of the rail section 3, there is an open/close switch 2 having a normally open contact for operating the high frequency oscillator 2o.
An actuating pin 22 is provided between the switch 21 and the actuating pin 22, and when the actuating pin 22 is deformed to a certain degree or more, the actuating pin 22 is provided, for example, in line with the slit portion 23& to prevent the deformation. 5 operation pin 2 due to difficulty in penetrating
A regulating portion 23 is provided that makes it impossible for the opening/closing switch 21 to operate due to the opening/closing switch 2.

Reference numeral 4 denotes a rotating mounting table for the purpose of improving heating unevenness, on which the object to be heated 5 and the saucer 6 are placed and rotated, such as SU 330.
It is held by a bottom plate 7 made of a magnetically permeable metal material such as No. 4. 8 is a motor that rotates a pulley 10 (around an r-axis 11) via a belt 9. The pulley 10 and the rotating mounting table 4 are provided with rollers 12 and 13, respectively.
, magnets 14 and 16 are provided, and the magnets 14 and 15 interact with each other to rotate the pulley 10 by separating the heating chamber bottom 16 and the bottom plate 7, which are made of a magnetically permeable metal material such as 5US304. is transmitted to the rotary mounting table 4, and the rotary mounting table 4 also rotates.

One end of the bottom plate 7 is removably fixed to the inner surface of the door body 2, which forms part of the wall surface of the heating chamber 1, via an insulating material 17, and the other end is held by a roller 18 made of an insulating material. . A heater 19 is another heat source of the heating chamber 1.

3 shows the door body 2 in an open state, and FIG. 4 shows the door body 2 in a state where it is removed from the heating chamber 1. By the way, when cleaning the inside of the heating chamber 1, the door body 2
4 and 6. If the door body 2 were to be dropped during this handling, it would be removed in the direction perpendicular to the door surface 2a of the door body 2. Planar members, that is, the rail portion 3 and the operating pin 22 in the example shown in the figure, are susceptible to impact, and if they receive an impact force above a certain level, these parts will naturally deform. Therefore, by setting the strength of the operating pin 220 to a suitable level, the operating pin 22 can be configured to deform when the door body 2 is subjected to an impact large enough to cause a problem in terms of radio wave leakage. The actuating pin 22, which has been deformed as shown by the two-dot chain line in Fig. 6, does not match the slit 23a of the regulating part 23, so the switch 21 is operated, but the high frequency oscillator is not activated, so the detachable sliding door body 2
It is possible to make a high frequency heating device with very stable operation.

As explained above, according to the present invention, the following effects can be expected.

1 The operating pin can play the role of a safety device against the impact force applied to the door body, and the door body slides perpendicularly to the heating chamber opening surface [7] to improve the safety of the detachable door body that opens and closes. It became possible to put it into practical use.

2. By providing the operating pin of the switch on a member on a plane substantially perpendicular to the door body surface, the degree of freedom in arranging the switch in the depth direction is increased, making the design extremely easy.
