Abstract
The invention discloses a micro-wave oven door including fire door glass, a door frame and a choke; the fire door glass composes the front screen of the fire door, the door frame is arranged on the back of the door glass, the choke is arranged between the outside of the door frame and the outside edge of the fire door glass, the edge covering and fixing the door frame and the fire door glass is formed with an arc prominency at the upper end of the fire door internal opening. The beneficial effect of the invention is: due to the protuberant arc formed at the upper end of the door internal opening contacting with the metal plate, a proper distance of the door and the front metal plate is ensured, which makes the generated hot energy by the microwave reasonably disperse, effectively improves the heat changing of the fire door and the terminal difference of the control plate.
Description
Technical field
The present invention relates to a kind of micro-wave oven, particularly relate to a kind of improvement structure of door of microwave oven.
Background technology
In general, micro-wave oven is a kind of with after placed within of the food, seal, connect the power supply of magnetron, make it produce high-frequency microwave, by waveguide high-frequency microwave is shone on the food, make about 2,400,000,000 5 thousand ten thousand times of hydrone internal vibration in a second of food, by the frictional heat that produces between hydrone household electrical appliance cooking food, heating.
As shown in Figure 1, Fig. 1 is the profile schematic diagram of the micro-wave oven in the prior art, and micro-wave oven 1 profile is cuboid, constitutes two sides and an end face by shell 10.Food can be placed in the inside of above-mentioned shell 10, constitutes the culinary art chamber 20 of cooking space.Culinary art chamber 20 is formed by connecting by the bending of a lot of sheet metallic plate, and the front is an opening.Culinary art is equipped with the rotary-tray 22 that can place food in the chamber 20, and this rotary-tray is by independent CD-ROM drive motor driven rotary, so that the food that is placed on the rotary-tray is evenly heated.Simultaneously, the frontal left of opening in culinary art chamber 20 is installed with the fire door 30 that can rotate to a side, rotate fire door 30 and the open front face of culinary art chamber 20 can be closed, thereby microwave is leaked to the outside when preventing to cook.In addition, be provided with electric control chamber on the right side of culinary art chamber 20, the front portion of this electric control chamber, the positive right side of face of promptly above-mentioned microwave oven 1 is an operation panel 40, this operation panel 40 constitutes the positive facial contour of microwave oven 1 with above-mentioned fire door 30.On operation panel 40, be separately installed with the control handle 42 and the operating buttons 44 of the work of operating electronic micro-wave oven, and the display screen 46 that can show the cooking status of the working condition of microwave oven and food.This electric control chamber is the place that the essential electric field part of microwave oven 1 work institute is installed, and magnetron, the high-tension transformer that high voltage source is provided and the capacitor of vibration generation microwave is equipped with in its inside; The microwave that magnetron produces exports through waveguide to waveguide, and through evenly dispersion after the stirring of agitator, microwave is from cavity top heating object to be heated.Described fire door 30 is made up of door body 31, choker 33 and door frame 34, and the central part of door body 31 is provided with a glass 32, and the user can observe the situation of inside cavity by door glass 32.Door body 31 is to make with the synthetic resin material, and door frame 34 then is to make with metal material.But there is following shortcoming in existing door of microwave oven: door of microwave oven makes a body produce heat fusing because the heat that microwave produces can accumulate in around the door frame in a large number; Because the gap is difficult to control between door-plate and the body of heater header board, thereby it is poor end to occur, makes the appearance damage of micro-wave oven, even the overall performance of micro-wave oven is affected.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides the front metal plate of a kind of door assembly and microwave oven cavity can keep the door for microwave oven of suitable distance.
The technical solution adopted in the present invention is: a kind of door of microwave oven comprises: fire door glass, door frame and choker; Described fire door glass constitutes the preceding screen of fire door, door frame is arranged on the back side of a glass, choker is arranged between doorframe Outboard Sections and the fire door glass outer side edge, covers in and be fixed on the marginal portion of doorframe and fire door glass, the integrally formed circular arc projection in the upper end of fire door internal orifice.
The diameter of described circular arc projection is 5-20mm.
The invention has the beneficial effects as follows: owing to form the circular arc that protrudes in the upper end of door body internal orifice; circular arc contacts with the front metal plate; guarantee the suitable distance of Men Tiyu front metal plate protection; the heat that microwave is produced can rationally disperse, and has effectively improved the thermal change phenomenon of fire door and the end difference problem of door-plate and control panel.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 4 is the outstanding circular arc schematic diagram in door of microwave oven internal orifice upper end.As shown in Figure 4, door of microwave oven comprises: fire door glass 100, door frame 200 and choker 300; Described fire door glass 100 constitutes the preceding screen of fire door, door frame 200 is arranged on the back side of a glass, choker 300 is arranged between the housing and fire door glass outer side edge of fire door internal orifice, cover in and be fixed on the marginal portion of doorframe and fire door glass, be formed with a circular arc projection 400 in the upper end of fire door internal orifice.The diameter of described circular arc projection 400 is 5-20mm, the degree of depth of circular arc projection 400 determines according to the different model of micro-wave oven, only need to guarantee that the door frame 200 and the gap of the metallic plate of body of heater front remain on the distance of 0.5mm, the metallic plate of choker and body of heater front remains on the 1.2mm distance for best.The gap of the metallic plate by control fire door and body of heater front, the gap of control gate framework and metallic plate and choker and metallic plate, the assurance heat can not assembled in door frame, choker and metallic plate contact portion, effectively eliminate the thermal change phenomenon, guarantees the quality of body of heater outward appearance.
It is worthy of note; protection scope of the present invention is not limited to above-mentioned instantiation mode, and according to basic fundamental design of the present invention, those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection scope of the present invention.
