Abstract
The present invention discloses a unique door structure of a microwave oven with a bent part which is assembled integrally. The present invention comprises a blocking cavity, a metal connecting part and a stamping part, wherein the blocking cavity is used for preventing microwave from leaking, and is provided with a local groove along the outer edge of a door; the metal connecting part is in contact with the edge of an opening of the microwave oven; the stamping part is steadily covered the front surface of the opening of the microwave oven.
Description
What the present invention relates to is the door structure of micro-wave oven.
The structure of conventional door of microwave oven as shown in Figure 2.Usually, micro-wave oven is to install like this: at first, alignd exactly with the bandy marginal portion of baking box 3 opening parts in the marginal portion of shell 1 opening part, then, the magnetron in the space installs between baking box 3 upper surfaces and the shell 1 with placing, so that the microwave radiation can be advanced in the baking box, the heat-resisting pallet 4 that food 5 is housed is placed in the bottom of baking box 3, again fire door A is contained in baking box 3(micro-wave oven B just) open front place, like this, fire door A just can be by random switch.
Structure description to the contact portion of fire door A and baking box 3 front portions is as follows.As shown in Figure 3, door body 7 has the flanging that a part does not have groove, and fixed head 8 is fastened on the interior flanging.Screw 12 tightly is fixed on barricade 11 between fixed head 8 and the internal hilar plate 10.The transparent material 9 that is close on barricade 11 inner surfaces is clamped by the flanging of internal hilar plate 10.Door 13 is placed between another edge at the outside turning of the edge at the outside turning of internal hilar plate 10 and door body 7, thereby one of peripheral edge portion formation along the door body stops cavity 6, this stops that the chamber is pressed on the edge of baking box 3 openings, to prevent that microwave is to external leakage.The periphery of door body 7 is equipped with the clamping plate 15 of front panel, and front panel is pressed on the front surface of a body 7, and clamping plate 15 are then fixed by screw 17.Utilize flanging, covered the surface of clamping plate 15, like this, the head of screw of screw 17 is just unlikely to come out.From said structure, can be clear that, the routine that in the outer rim of door body, forms stop the chamber, need to use multiple parts, comprise clamping plate 15, flanging 16, internal hilar plate 10, fixed head 8, screw 12 and 17 or the like.Before finally being assembled into a complete door body, all these parts all are fastening with screw.As a result, the door body need use many parts, makes assembling process complicated so inevitably, and then has reduced productivity ratio, has improved production cost.
In view of in the stove gate device production of routine, remain above-mentioned defective, the present invention is intended to simplify door structure, boost productivity, reduce production costs by reducing number of components and parts effectively, thereby a kind of door of microwave oven device of uniqueness is provided.Particularly, most preferred embodiment of the present invention provides punch components, metal connection parts for micro-wave oven and has stopped the door assembly of the uniqueness that the chamber is integrated.Especially, most preferred embodiment provides a kind of integral door assembly that is contained in the micro-wave oven stokehold, comprising a type groove that stops the chamber and be positioned at the neighboring of a body, passes through the outer rim of a body to external leakage in order to prevent microwave effectively; Metal connection parts that links to each other with the part of micro-wave oven opening part periphery and the punch components that covers the opening part front surface, all these parts all are combined in together with the shape of bending.
Fig. 1 is a profile that has amplified, demonstration be the structure of the stove gate device of reflection most preferred embodiment of the present invention.
Fig. 2 is the profile of the micro-wave oven of routine.
Fig. 3 is a profile that has amplified, demonstration be the door structure of conventional micro-wave oven.
Referring now to accompanying drawing most preferred embodiment of the present invention is described.The fire door A that is fixed on micro-wave oven B front openings place comprises that one is stopped chamber 6a and is positioned at the type groove of the external periphery of door by what limit 18,19 and 20 limited.Punch components 21 is joined with the metal connection parts 23 that is close to micro-wave oven B front portion 26, and wherein, punch components 21 links to each other with stopping chamber 6a in the center near fire door.Front panel 14a is fixed on the front portion of a body 7, so that front panel 14a can be around the outer rim of living door body 7.Inside groove 24 is opened the inboard of the marginal portion 14b of plate 14a in front, and is complementary with the edge surface of the bent face 20 of door body 7.By projection 25 is embedded inside groove 24, just make door 13a seal the opening that stops chamber 6a, then front panel 14a is fastened on the body 7, like this, door has just installed.As long as door 13a is embedded in the inside groove at front panel 14a rear portion, just can securely door body 7 and front panel 14a be fitted together.Therefore, can finish the assembly work of fire door at an easy rate.In addition, because front panel 14a is integrally formed along the outer rim that stops chamber 6a, so, the screw that it will install usefulness covers fully, thereby can obtain satisfactory appearance, hyaline membrane 22 is close together with punch components, so that can face the opening of micro-wave oven.
As mentioned above, most preferred embodiment of the present invention, provide a kind of flute profile that forms along the neighboring of door body 7 to stop chamber 6a, and, just can at an easy rate front panel 14a be fitted together with a door body 7 as long as the projection 25 at baffle plate 13a top is embedded the inside groove that wraps on the front panel 14a edge that stops on the 6a neighboring, chamber.And metal connection parts 23 and stop that the overall structure of chamber 6a does not have seam is fully yet so just guaranteed the sealing of baking box opening part, has eliminated even the possibility of the most micro-microwave leakage.Most preferred embodiment of the present invention provides aforesaid door structure, and wherein stop chamber, metal connection parts and punch components are combined in together by effectively utilizing the fire door assembly.With internal hilar plate, shield member and door body mutually the door structure of discrete routine compare, stove gate device structure of the present invention has significantly reduced number of components and parts.Therefore, most preferred embodiment of the present invention provides a kind of door structure of having simplified, and this door structure has finally reduced the whole production cost, improved production efficiency.
