Problems solved by technology

At this time, when the door bolt has disengaged from the door bolt groove, if the force of pulling the door handle 13 cannot be reduced and continues to be pulled open with the same force, the furnace door 11 may rotate sharply.
In this way, the heated high-temperature air inside the cooking chamber is rapidly discharged outside during the cooking process, and the user may be scalded by such high-temperature air.

Embodiment Construction

[0025] The microwave oven door switch device of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] Figure 2 to Figure 4 An embodiment of the microwave oven door opening and closing device of the present invention is illustrated in FIG.

[0027] As shown in the figure, the oven door 20 of the microwave oven is centered on the hinge H and is arranged on the cabinet 10 (refer to figure 1 ) can be rotated back and forth. A protruding plate 30 is provided on the upper side of the furnace door 20, and the furnace door 20 is connected to the hinge H.

[0028] There are elastic elastic protrusions on the raised plate 30, and the elastic protrusions have elasticity up and down. The elastic protrusion 31 is a part of the upper part of the raised plate 30 and protrudes upwards. In the embodiment in the figure, the elastic protrusion 31 is formed by extending with a certain slope relative to the horizontal axis...

Abstract

This invention provides an on-off device of microwave oven door, which comprises a fire door setting in one side of the oven box and which can be rotary, a stripe grating widow setting in the upper of the box; in the upper of the fire door or the bottom of the stripe grating widow it has at least one elastic projection, and at least one hood projection, wherein the projection is set in the place contacting the external margin of the elastic projection. Said device can adjust the rotary speed of the fire door, and prevent the high-heat air discharging outside when the fire door rotary rapidly.

Description

technical field [0001] The present invention is an invention related to a microwave oven, in particular an invention related to a switch device for a door of the microwave oven. Background technique [0002] like figure 1 As shown, one side of the microwave oven cabinet 10 is provided with an oven door 11 . Fire door 11 is the cooking chamber that is used for selective switch to be arranged on cabinet 10 inside, and the left side end of fire door 11 in the figure is hingedly connected with cabinet 10, and the back right side end of fire door 11 among the figure and is close to A door latch and a door latch slot (not shown) are respectively provided on the front side of the cabinet 10 thereon. [0003] When the oven door 11 seals the cooking chamber, the door bolt is inserted and fixed in the door bolt seam to prevent the oven door 11 from shaking arbitrarily. In this case, hold the handle 13 in the figure, that is, the door handle 13 arranged on the front right side of th...
