Description

Microwave oven door structure

Technical field

The present invention relates to a kind of door for microwave oven, particularly a kind of microwave oven door structure.

Background technology

Along with the quickening of people's work, rhythm of life, the consumer has higher requirement to the convenience of the working service of product.Micro-wave oven reaches a kind of household appliances about 80% as a kind of in a line city popularity rate, and its working service convenience is significant.

Usually the fire door ecto-entad of micro-wave oven is disposed with fire door glass 21, fire door housing 22, door body 23 and transparent pad pasting 24 and (sees Fig. 5-Fig. 8).The door body is to be used for the main structural components that shielded microwave oven prevents microwave leakage on the door for microwave oven, and the door body is by choke coil 25, and seal junction 26 and metal shielding board 27 are formed, and louver of plastic 28 is installed on the choke coil.In the use, microwave oven cooking chamber internal emission stops through the seal junction earlier to the microwave around the door, remains a small amount of microwave and eliminate through choke coil.Its structure can cause the fire door inner surface cooperation of a lot of parts to occur, makes the user cannot handle its surperficial cleaning problems well, also is prone to the problem that steam enters fire door simultaneously.

The electromagnetic wave screening structure that Chinese patent literature CN1752571A discloses a kind of door for microwave oven on March 29th, 2006, comprise doorframe, the edge sealing surface, the door obstruction piece, doorframe one side is provided with gate stop, doorframe is the framework of the door assembly in sealing barbecue front, chamber, it is characterized in that: edge sealing surface warpage is formed on the edge of doorframe, the electromagnetic wave that shielding leaks from the door edge, obstruction piece is combined in the edge of doorframe, have several warpage faces, the electromagnetic wave that shielding leaks from the edge of door assembly, in the door obstruction piece on the doorframe edge, wherein the door obstruction piece of partial blockage part shape and other parts is different, be in the door obstruction piece on the doorframe edge, the fabric width of partial blockage part lateral surface is less than the fabric width of the door obstruction piece lateral surface of other parts.It is said that it effectively shields the electromagnetic wave of a plurality of angles and the electromagnetic wave of various waveforms, can improve the safety in utilization of product, and then improve the credit worthiness of product.But its structure is comparatively complicated, and parts are many, are unfavorable for the promotion and application of product.Therefore, be necessary to be further improved and perfect.

Summary of the invention

Purpose of the present invention aims to provide a kind of microwave oven door structure of simple and reasonable, the easy and easy cleaning of assembling, to overcome weak point of the prior art.

By a kind of microwave oven door structure of this purpose design, comprise that ecto-entad is disposed with glass in fire door glass, fire door housing, door body and the fire door, its architectural feature is to be provided with the shield assembly that is used for shield microwaves between the glass in a body and the fire door.

Described shield assembly is made up of seal junction, metal shielding board and choke coil that outer circumferentially middle part is set in turn on the body.

The middle part of described seal junction is provided with mounting groove, and the periphery of mounting groove and seal junction forms annular boss; Metal shielding board is fixedly welded in the mounting groove of seal junction.

Glass is fixed on the boss of seal junction in the described fire door, perhaps links to each other by silica gel sealing; Choke coil is arranged between metal shielding board and the interior glass of fire door.

Described choke coil and seal junction are the split setting; One side of choke coil is fixing along the inboard welding of the boss of seal junction, the interior glassy phase of the opposite side of choke coil and fire door against.

Described Men Tiyu fire door housing cooperates fixing, and fire door glass links to each other with the pivot joint of fire door housing or is hinged and connected; The fire door pilot hole that is complementary with handle that offers on glass, handle links to each other with fire door glass by securing member.

The present invention has following beneficial effect: 1. reduced the parts of door for microwave oven body inboard, it is more reasonable tight that it is cooperated each other; 2. make not only that the door body inside of being seen when beating opening door body is more attractive in appearance, also make the user can be good at the door for microwave oven inner surface after using is cleaned simultaneously, and prevented that steam from entering fire door inside; It has the characteristics of reasonable, the both artistic and practical and low cost of manufacture of simplicity of design.
