The door hook (13) comprises door switches (14) and (16) switched to conduct a power circuit for heating when the engagement parts (11a) and (11b) are brought into contact with the switches, and the door key (11) is provided with a play at its connection part with a handle (5) by an amount equal to the travel of the door key in the longitudinal direction when the opening / closing door (4) in opened state is brought into a closed state.

Description

technical field [0001] The present invention relates to a heating device such as a microwave oven, and more particularly, the present invention relates to a structure of a door opening and closing part of a cooking device. Background technique [0002] When using a microwave oven, the object to be cooked is placed in the microwave oven, and the oven door is closed to start providing microwaves. However, if the microwave is supplied in a state where the door is not completely closed, for example, the engaging part provided on the upper part of the door is locked on the side of the furnace main body, and the microwave is provided under the condition that the engaging part provided on the lower part of the door is not locked, there is a concern that the microwave may leak out. the furnace. For this reason, a microwave oven usually includes a door opening and closing part, which is provided with an element for detecting that the door is completely closed, and only when the door...

Problems solved by technology

Also, in this state, when the foreign matter 118 dries, and when the engaging portion 112b is operated, the dried foreign matter 118 remains and adheres to the engaging portion 112b, there is a fear that the engaging portion 112b is pressed down. The operation timing of the operation portion 114a of the door switch 114 may deviate from the normal timing

In addition, when the engaging portion 112b is operated before the foreign matter 118 dries, there is a fear that the foreign matter 118 will move the operating portion 114a of the door switch 114 from the front end portion of the engaging portion 112b, causing the operation of the door switch 114 to fail.

In other words, the downward protrusion of the engaging portions 112a and 112b makes it difficult to confirm the adhesion of the foreign matter 118, and also makes it difficult to clean the door opening and closing member 110.

This type of problem may also occur on the door opening and closing member 130 as shown in FIG. class questions
