[0006] However, at this time, since the space inside the main body determines the direction corresponding to the key switch part to arrange three independently installed micro switches, it is necessary to install the space for these three switches, and the key switch part of the door and the switch lever on the main body side. The switch space that advances, retreats and tilts in the opening and closing direction increases the overall size of the switch mechanism and increases the number of parts, thus increasing the cost
In addition, the installation direction of the three micro switches is restricted in the installation direction of the switch due to the corresponding relationship with the key switch part and the switch lever, which limits the installation direction of each switch
In particular, it is difficult to align the directions of the terminals of the switch in different directions, and the wiring work takes time.

Embodiment
[0065] Next, an embodiment of the present invention will be described with reference to the drawings. The attached drawing shows the door switch for the high frequency heating device, figure 1 Among them, the door switch 11 is constructed as follows. The switch unit 13 and the micro switch (hereinafter referred to as the latch switch) SW1 are installed on one wall surface of the switch mounting plate 12, which is vertically arranged on the long substrate, and are arranged on the main body side, so that the door is opposite to it. Towards.
[0066] The above-mentioned switch unit 13 such as figure 2 As shown, the switch box 14 is integrally constructed by incorporating the lower end of the gently arc-shaped tilting rod 15, and a short-circuit switch SW2 and a door switch (signal switch) described later are incorporated in parallel in the inside of the switch box 14. SW3 two switches. Then, the switch case 14 is attached to the upper part of one wall surface of the switch mo...

The aim of the invention is to assemble a plurality of switches into one switch case to form a unit and miniaturize a high frequency heating device, reduce the number of parts of the switch to reduce cost and save a space, and increase the degree of freedom in the direction of switch mounting in a main body to improve to efficiency of wiring work markedly when manufacturing the door switch of the high frequency heating device. This high frequency heating device is provided with a first switch for switching contact parts by displacing an electrical conductive contact piece elastically when an inclination lever tilts and a second switch for switching contact parts by displacing the other electrical conductive contact piece elastically at the other timing different slightly from timing for switching contact parts of the first switch when the inclination lever tilts in the switch case.
Description
technical field [0001] The present invention relates to a high-frequency heating device that effectively incorporates a plurality of switches that are operated in conjunction with opening and closing of a door into one switch box, thereby achieving miniaturization and improvement in switching performance of the switches. Background technique [0002] Next, a high-frequency heating device will be described as an example. Regarding the opening and closing operation of the door when using a high-frequency heating device, high safety is required so as not to pose a danger to the human body. Usually, in terms of safety standards, it is obligatory to incorporate a latch switch, a door switch, and a short-circuit switch (monitoring switch) Three types of switches are used, and the latch switch and the short-circuit switch are separated by a certain distance to ensure safe switching performance. Furthermore, these switches are operated with a time difference in conjunction with the...
