Embodiment Construction
[0025] The assembly for the washing machine of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:
[0026] In order to achieve the above object, the present invention provides an exhaust gas throttle structure of a microwave oven characterized by the following structure: the technical solution adopted by the present invention is to design an exhaust gas throttle structure of a microwave oven, including the exhaust gas on the outer box of the microwave oven. Port 102a and throttle valve 132 are characterized in that a support plate 112 is provided on the external box, and a through hole corresponding to the exhaust port 102a is opened on the support plate 112. The left and right sides are respectively provided with brackets with coupling holes 112c'; the pin shafts 132c' at the ends of the throttle valve 132 are respectively inserted into the coupling holes 112c' of the support plate 112, so tha...

The invention provides an exhaust gas throttle structure of a microwave oven, which includes an exhaust port and a throttle valve on the outer box body of the microwave oven, and is characterized in that a support plate is arranged on the outer box body, and a There are through holes corresponding to the exhaust port, and brackets with joint holes are provided on the left and right sides of the support plate; the end pins on both sides of the throttle are respectively inserted into the joint holes of the support plate, The throttle valve is rotatably connected to one side of the support plate with one side of the support plate as a rotation axis. An inwardly inclined limit bracket is provided on the rear end of the support plate to limit the opening angle of the throttle valve. The beneficial effect of the present invention is that the exhaust gas throttle structure can be formed without additional adapters, which reduces the manufacturing cost and simplifies the assembly process of the exhaust gas throttle structure.
Description
technical field [0001] The present invention relates to an invention of a microwave oven, especially an invention of an exhaust gas throttle structure installed on the outer box of the microwave oven to discharge the air flowing into the microwave oven to the outside. Background technique [0002] The exhaust structure of a general microwave oven is as follows: figure 1 As shown, the top of the external box body 2 of the microwave oven is formed with an exhaust port 2a, and the exhaust port 2a is a passage through which the air flowing into the microwave oven through the suction grid (not shown in the drawings) is discharged to the outside. right. Both sides of the exhaust port 2a are formed with a fixed joint hole 2b', and a support plate 12 is arranged on the top of the exhaust port 2a. The support plate 12 is arranged on both sides of the fixed joint hole 2b' of the above-mentioned exhaust port 2a to support The plate 12 is formed of a thin flat plate, and a pair of thr...
