Abstract
The invention discloses a keystroke structure of a micro-wave oven door, which comprises a front end control panel, a keystroke hole formed at the lower part of the front end control panel and a control rod arranged at the back side of the keystroke hole and used for controlling the opening and closing of the door; a keystroke hinged and combined with the upper end of the keystroke hole and used for pushing the control rod is arranged in the keystroke hole. The keystroke comprises a keystroke surface, a keystroke push rod arranged at the back side of the keystroke surface and used for pushing the control rod as well as two hinge shafts respectively formed on the two sides at the upper end of the keystroke surface. A spring is sheathed on the keystroke push rod; the spring is arranged in the keystroke hole which is formed with a holding space. As the shaft fixation mode is adopted by the keystroke structure of the micro-wave oven door, a plurality of locating holes in the prior art are not needed and structures which generate friction do not exist; the keystroke structure can be fast rebounded through the spring after being pressed down, thereby avoiding the situation that the keystroke is blocked, and greatly improving the production efficiency and the service life of the micro-wave oven.
Description
Technical field
The present invention relates to a kind of micro-wave oven.Particularly relate to a kind of simple in structurely, can prevent the press-key structure of the door for microwave oven of button stuck phenomenon.
Background technology
Usually, micro-wave oven is that (per second is about 2,450MHz) is heating source, by upsetting the molecules align of food, utilizes the electrical installation of the frictional heat heat food between the molecule with high frequency.
Such micro-wave oven is made of fuselage 10 that has possessed front panel 11, shell 12, rear board 13 and the electric control chamber that constitutes the cavity 20 of heating clamber and be provided with various electronic components as shown in Figure 1.
Shell 12 is protected cavity 20 and electric control chamber with front panel 11 and rear board 13 in two sides that constitute fuselage 10 and end face.
Be provided with the magnetron 31 of launched microwave in the inside of electric control chamber; High-tension high-tension transformer 32 is provided for magnetron 31; Be used to cool off the Air Blast fan 33 of fuselage 10 inner various electrical equipments and the various parts such as fan electromotor 34 that drive Air Blast fan 33.
The lateral surface of cavity 20 is provided with the waveguide 36 of guiding microwave, and the front portion structure of magnetron 31 is arranged on the inside of waveguide 36.
For radiated microwaves, the side that it installs the cavity 20 of waveguide 36 communicates with the inner space of waveguide 36, and the medial surface of cavity 20 is provided with the guard shield that seals the part that communicates.The main effect of guard shield is to prevent that food slag or wet goods foreign matter from entering the inside of magnetron 31.
The front-end control panel 1 that constitutes fuselage 10 front structures is installed on the front panel 11, and can opens or close the fire door 14 of cavity 20 inside, and the press-key structure 16 that is installed in front-end control panel 1 bottom control fire door 14 switches.
As Fig. 2, Fig. 3, shown in Figure 4, the described press-key structure 16 that is installed in front-end control panel 1 bottom control fire door 14 switches includes: front-end control panel 1, and the button that is positioned at front-end control panel 1 bottom and is formed with a plurality of locating holes 4 supports 17; Be positioned at locating hole 4 rear sides, be used to control the control lever 3 of stove door switch; In the locating hole 4 of button support 17, be provided with the button 2 that is used for push lever 3.Wherein, button 2 is formed with a plurality of push rods 15 that are inserted in the locating hole 4, are used for push lever 3 at its rear side as shown in Figure 5.
When needs are opened fire door 14, press button 5 in front, push rod 15 push levers 3 of button 5 back, the pull-up of control lever 3 turns impelling gate stop, thus fire door 14 is ejected.
But, above-mentioned press-key structure 16, when pressing button 5, gate stop is given 3 one power of control lever, control lever 3 is given 2 one power of button again, causes push rod 15 and the several position place between the locating hole 4 on the button 2 to produce bigger frictional force, if frictional force is greater than the elastic force of spring 18, button 5 then occurs and be stuck, the situation that can't reset.90% this situation about being stuck of product appearance will be arranged when producing micro-wave oven.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of simple in structure, can prevent the press-key structure of the door for microwave oven of button stuck phenomenon.
The technical solution adopted in the present invention is: a kind of press-key structure of door for microwave oven, include the front-end control panel, be formed on the key hole of front-end control panel bottom, be positioned at the key hole rear side, be used for the control lever of control gate switch, in key hole, be provided with and the hinged button that combines, is used for push lever in key hole upper end.
Described button includes the button face; Be positioned at the rear side of button face and be connected as a single entity, be used for the button push rod of push lever with the button face; And the hinge that is respectively formed at both sides, button face upper end.
Also be with spring on the described button push rod, described spring is positioned at the key hole that is formed with spatial accommodation.
The press-key structure of door for microwave oven of the present invention, owing to adopt the fixing mode of axle, need not to use a plurality of locating hole of the prior art, there is not the structure that produces friction, can be after pressing by very fast being rebounded of spring, thereby avoided occurring the situation that button is stuck, greatly improved production efficiency, and the use of microwave ovens life-span.
