Description
Technical field
The present invention relates to the micro-wave oven that a kind of door for microwave oven body structure and employing have this door body structure.
Background technology
Micro-wave oven use high-frequency microwave generator produces high-frequency microwave and carrys out cooking food.General micro-wave oven comprises: high-frequency microwave generator, has the body of heater of cooking room, and opens and closes the fire door of cooking room entrance.Being supplied to the high-frequency microwave that cooking room carries out cooking is harmful to human body, so should make the structure that the fire door of micro-wave oven becomes to prevent this from occurring with Proper Design.The existing various technology preventing microwave leakage, the most general is the strangler structure be arranged on fire door.This strangler structure is that the precalculated position on the body of heater or fire door of micro-wave oven is formed to the recess of shaped.The degree of depth of recess is equivalent to 1/4 of the wavelength of the microwave cooked, and the resistance value of this recess open end is infinitely great, thus restriction microwave leakage.In addition, existing door for microwave oven body, for the ease of observing cooking chamber furnace chamber inner case, general meeting arranges the observation mesh of the dense distribution for observing cooking chamber furnace chamber inside on door body, although it is very tiny to observe mesh, the microwave leakage caused is also smaller, but due to the area observing mesh comparatively large, totally out still there is certain leakage rate.
Summary of the invention
Primary technical problem to be solved by this invention provides a kind of door for microwave oven body structure for above-mentioned prior art for above-mentioned prior art, and this door body structure can improve fire door observation window place microwave leakage.
The further technical problem to be solved of the present invention provides a kind of micro-wave oven for above-mentioned prior art for above-mentioned prior art, and the door body structure of this micro-wave oven can improve fire door observation window place microwave leakage.
The present invention solves the technical scheme that above-mentioned technology matter of utmost importance adopts: a kind of door for microwave oven body structure, comprise protecting metal door body, the observation mesh of the dense distribution for observing cooking chamber furnace chamber inside is provided with in the middle part of described protecting metal door body, it is characterized in that: described protecting metal door body side is provided with a metal plate be arranged in parallel with protecting metal door body, mesh observed by the flat board this metal plate being also provided with dense distribution.
As improvement, described metal plate is fixed on the side of protecting metal door body cooking chamber furnace chamber dorsad.
Improve, described metal plate is integrally fixed on protecting metal door body or described metal plate is the projective table type flat board directly stretching on metal plate again.
Improve, the diameter that mesh observed by the observation mesh on protecting metal door body and the flat board on metal plate is all less than 1.5mm again.
Improve, the observation mesh on protecting metal door body and the flat board on metal plate are observed mesh and are overlapped with one heart or completely viewed from vertical metal door body and metal plate angle again.
Improve, both can seamlessly fix between described metal plate and described protecting metal door body, also can have certain gap, the gap between described metal plate and described protecting metal door body is preferably λ/4n, and wherein n is natural number, and λ is microwave wavelength.
The present invention solves the technical scheme that above-mentioned further technical problem adopts: a kind of micro-wave oven, comprise body of heater, microwave generator, furnace chamber and fire door is provided with in body of heater, fire door comprises protecting metal door body, the observation mesh of the dense distribution for observing cooking chamber furnace chamber inside is provided with in the middle part of described protecting metal door body, it is characterized in that: described protecting metal door body side is provided with a metal plate be arranged in parallel with protecting metal door body, mesh observed by the flat board this metal plate being also provided with dense distribution.
Compared with prior art, the invention has the advantages that: a metal plate be arranged in parallel with protecting metal door body is set on door body, mesh observed by the flat board this metal plate being also provided with dense distribution, thus secondary shield is carried out to the microwave leaked out from protecting metal door body observation window, guarantee that the microwave major part that part spills from observation mesh is reflected back furnace chamber, greatly reduce the microwave leakage that window place seen by fire door, thus improve the efficiency of heating surface of microwave further, better ensure that the use safety of client.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
The present embodiment provide firstly a kind of door for microwave oven body structure, shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, it comprises protecting metal door body 2, the observation mesh 21 of the dense distribution for observing cooking chamber furnace chamber inside is provided with in the middle part of described protecting metal door body 2, described protecting metal door body side is provided with a metal plate 3 be arranged in parallel with protecting metal door body, and mesh 31 observed by the flat board this metal plate being also provided with dense distribution.
In the present embodiment, described metal plate 3 is fixed on the side of protecting metal door body cooking chamber furnace chamber dorsad, and is direct stretching on metal plate and the projective table type that goes out is dull and stereotyped; Certainly, metal plate 3 also can directly integrally be weldingly fixed on protecting metal door body.The diameter that mesh observed by observation mesh on protecting metal door body and the flat board on metal plate is all less than 1.5mm.In the present embodiment, the diameter that mesh observed by observation mesh on protecting metal door body and the flat board on metal plate is 1mm, and the observation mesh on protecting metal door body and the observation of the flat board on metal plate mesh finish watching full weight conjunction from vertical metal door body and metal plate angle.When the diameter that mesh observed by the observation mesh on protecting metal door body and the flat board on metal plate is not identical, the observation mesh on protecting metal door body and the flat board on metal plate is preferably made to observe mesh concentric viewed from vertical metal door body and metal plate angle.The food cooking situation observing furnace chamber can better be ensured like this.Gap d between described metal plate and described protecting metal door body is λ/4n, and wherein n is natural number, and λ is microwave wavelength.
This door body structure, observed the metal plate of mesh by newly-increased one deck band, opposite house body observation window place carries out double layer screen, greatly reduces the microwave External leakage at fire door observation window place, improves microwave efficiency, better ensure that the use safety of client simultaneously.
Adopt the micro-wave oven having above-mentioned door body structure, shown in Fig. 5, Fig. 6, it comprises body of heater 1, and be provided with microwave generator, furnace chamber 4 and fire door in body of heater, namely fire door adopts the door body structure of foregoing description structure.
