Abstract
The utility model discloses a microwave oven, which comprises a cavity body, a microwave generator, a waveguide tube used for guiding microwave into the cavity, and a waveguide tube fixing sheet, wherein the waveguide tube fixing sheet adopts a right-angled plate sheet structure, is clung to the side face and the lower side of the cavity, and is mounted on the cavity in a cladding manner; the waveguide tube corresponding to the waveguide tube fixing sheet adopts a right-angled groove-shaped structure, and comprises a vertical part and a horizontal part; a bent opening is formed at the junction of the vertical part and the horizontal part; the waveguide tube is mounted outside the waveguide tube fixing sheet in a matched manner to commonly form a microwave channel; the horizontal part is longer than the lower end of the waveguide tube fixing sheet and forms a microwave feedback port; and the microwave generator is mounted outside the top of the vertical part of the waveguide tube. The microwave oven is characterized in that retaining sheets are respectively fixed on the inner side of the bent opening. According to the microwave oven provided by the utility model, the retaining sheets are fixed at the bent opening of the waveguide tube, so that the microwave leakage is fundamentally avoided, the safety performance of the microwave oven is greatly improved, the structure is simple, the cost is low, and the effect is obvious.
Description
Technical field
The utility model relates to a kind of micro-wave oven, and particularly a kind of waveguide structure is through the micro-wave oven of improvement.
Background technology
The micro-wave oven of prior art is as shown in Figure 1; Generally all comprise cavity 1, microwave generating apparatus 2, be used for microwave is imported waveguide 3 and waveguide stator 4 in the cavity; Waveguide stator 4 rectangular types wherein; Be close to cavity 1 coating and be installed in its right side and downside, the also rectangular type of waveguide 3, as shown in Figure 2; Its vertical portion 31 cooperates the outside that is installed in waveguide stator 4 to form microwave channel jointly with transverse part 32, and transverse part 32 is long and formation microwave feedback port 33 than the lower end of waveguide stator 4; Microwave generating apparatus 2 is positioned at the right side of cavity 1 and is installed in the outside, upper end of waveguide 3.
The defective part of said structure is: waveguide 3 is formed by the whole bending of metal material; Because the existence of folding s tress, the vertical portion 31 of the waveguide 3 after the bending and the intersection (being kink) of transverse part 32 form gap 34, when micro-wave oven is worked; The microwave that microwave generating apparatus 2 produces gets in the process of transverse part 32 from vertical portion 31; Cause microwave leakage easily, make that the security performance of micro-wave oven is not up to standard, also be prone to human body is damaged.
Summary of the invention
The purpose of the utility model be to consider the problems referred to above and provide a kind of reasonable in design, simple, can avoid microwave leakage, micro-wave oven that safety coefficient is high.
The technical scheme of the utility model is: a kind of micro-wave oven; Comprise cavity, microwave generating apparatus, be used for microwave is imported waveguide and waveguide stator in the cavity; The rectangular sheet structure of waveguide stator wherein, side and the downside of being close to cavity coat the rectangular trench structure of waveguide mounted thereto, corresponding; Comprise vertical portion and transverse part; Vertical portion and transverse part intersection form the bending gap, and waveguide cooperates the outside that is installed in the waveguide stator to form microwave channel jointly, and its transverse part is long and formation microwave feedback port than the lower end of waveguide stator; Microwave generating apparatus is installed in the top outer of the vertical portion of waveguide, it is characterized in that said bending gap inboard is fixed with catch respectively.
Said catch is processed by metallic plate punching, and its angle and width and bending gap are complementary and shelter from gap fully.
The equal correspondence in the bending part of said catch and waveguide is provided with locating hole.
The gap position that the utility model is employed in the bending part of waveguide is fixed with the structure of catch, has avoided microwave leakage fully, has improved the security performance of micro-wave oven greatly, and is not only simple in structure, and with low cost, and effect is remarkable.

Fig. 1 is existing microwave oven structure sketch map;
Fig. 2 is the waveguide of Fig. 1 and the connection sketch map of waveguide stator;
Fig. 3 is that the waveguide and the waveguide stator of the utility model installed the decomposition texture sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model done further describing.
With reference to Fig. 1, shown in 3; The utility model micro-wave oven comprises cavity 1, microwave generating apparatus 2, is used for microwave is imported waveguide 3 and waveguide stator 4 in the cavity, wherein waveguide stator 4 rectangular sheet structures; Right side and the downside of being close to cavity 1 coat mounted thereto; Corresponding waveguide 3 rectangular trench structures comprise vertical portion 31 and transverse part 32, and vertical portion 31 forms two bending gap 34 with transverse part 32 intersections; Waveguide 3 cooperates the outside that is installed in waveguide stator 4 to form microwave channel jointly; Its transverse part 32 is long and formation microwave feedback port 33 than the lower end of waveguide stator 4, and microwave generating apparatus 2 is installed in the top outer of the vertical portion 31 of waveguide 3, and said two bending gap 34 inboards are fixed with catch 5 respectively.
In the present embodiment, said catch 5 is processed by metallic plate punching, and its angle and width and bending gap 34 are complementary and shelter from gap fully.For conveniently catch being weldingly fixed on the inboard of bending gap, the equal correspondence in bending part of said catch 5 and waveguide 3 is provided with locating hole.
