Abstract
The present invention relates to a microwave oven door with a microwave absorbing cavity, which relates to a microwave leakage preventing device which is especially used for microwave ovens. The microwave absorbing cavity is utilized to absorb microwaves to prevent the microwaves from outward leaking to damage the microwave oven door with a microwave absorbing cavity of the user. The inner side surface of the oven door and the front side of the oven chamber are respectively provided with a groove in order to hold the microwave absorbing cavity. The groove is welded or is made into section to be fixed on the inner side surface of the oven door, and an oven chamber opening is provided with a circle of bosses. The microwave absorbing cavity is a quadrangle cavity body of which the cross section is in a G shape. The inner side surface of the oven chamber opening is provided with a sliver-shaped opening of which the inner wall is a metallic layer and the inner wall is a plastic layer. Special materials for absorbing the microwaves are filled between the metallic layer and the plastic layer. After the oven door is closed, the leaked microwaves can be completely absorbed by microwave absorbing materials, and therefore, the microwaves can not leak out of the oven. The present invention solves the problem that after the existing microwave oven is used for a long time, owing to abrasion, the gap between the oven door and the oven chamber is increased, which causes the microwave leakage quantity to be increased. The present invention adds a reliable barrier for the microwave oven to guarantee the user safety for longtime and ensure that the user can not be harmed by microwave radiation.
Description
One, technical field
The present invention relates to a kind of anti-microwave leakage device,, absorb microwave by microwave absorbing chamber and prevent the door for microwave oven of microwave to external leakage injury user's band microwave absorbing chamber in particular for micro-wave oven.
Two, background technology
Micro-wave oven is the electrical equipment that generally uses in the Modern Family kitchen, and microwave has certain harm to human body, thereby as the micro-wave oven of household electrical appliance, the anti-leak problem is particularly important.Microwave leakage is meant that microwave leaks into the stove external space from source or heater (furnace chamber), and fire door is placed food and observed furnace chamber and use, and also is an antetheca that constitutes furnace chamber, and leakage problem is the most outstanding.The method that adopts is except interlocking on the electrical equipment now, mechanically be at place, slit dress gasket, tightly be attached between fire door and the furnace chamber and absorb microwave, and fire door is after multiple switching wearing and tearing, and the slit will be strengthened, and cause blow-by between fire door and furnace chamber, the effect of gasket just reduces, the microwave leakage amount increases, and is above standard, and the user is damaged.
Three, summary of the invention
The objective of the invention is to solve the problems of the prior art, a kind of novel microwave fire door with microwave absorbing chamber is provided, it is made in microwave absorbing chamber, and the absorption microwave prevents microwave to external leakage on the fire door, guarantees user's safety for a long time.
Concrete scheme of the present invention is: do a groove respectively to hold microwave absorbing chamber at fire door medial surface and furnace chamber front, the degree of depth of the degree of depth of fire door groove and furnace chamber groove can change between the thickness of microwave absorbing chamber zero, and their sums equate with the thickness of microwave absorbing chamber.Microwave absorbing chamber is a quadrangle cavity, and the cross section on its each limit is the G font, and promptly there is being rectangular opening on each limit near on the side of furnace chamber mouth, and its outer wall is a metal level, and inwall is a plastic layer, is full of the material that absorbs microwave between metal level and plastic layer; Microwave absorbing chamber is fixed on the fire door medial surface for welding or making section bar.On the furnace chamber mouth, do all boss, its housing size is consistent with the groove size that microwave absorbing chamber forms, its height is consistent with the degree of depth of groove, like this, after fire door closes, boss just is absorbed in the groove of microwave absorbing chamber composition, and tightly fit with the fire door inwall, leak microwave by the slit between fire door and furnace chamber boss after owing to its direct projection, will enter microwave absorbing chamber by the rectangular opening of microwave absorbing chamber medial surface, and reflection is passed plastic layer and is absorbed fully by the microwave absorbing material of inside within it, and can not leak into outside the stove.
The invention has the beneficial effects as follows: make micro-wave oven on the basis of existing anti-microwave leakage method, add barrier again one, microwave absorbing chamber and fire door are fixed, microwave absorbing material effectively absorbs the leakage microwave in it, can not make microwave by the fire door slot leakage, the influence that its effect is not strengthened by can in fire door wearing and tearing slit, can guarantee user's safety for a long time, can not worry to be subjected to the harm of microwave irradiation.
Four, description of drawings
Fig. 1 is the schematic perspective view after door of microwave oven of the present invention is opened;
Fig. 2 and Fig. 3 are that microwave absorbing chamber absorbs the microwave process schematic diagram on the door for microwave oven of the present invention, and arrow is represented the microwave leakage direction among the figure.
As follows to the label declaration in each width of cloth accompanying drawing: the 1-furnace chamber; The 1a-boss; 1b-furnace chamber groove; The 2-microwave absorbing chamber; The rectangular opening of 2a-; The 2b-metal; The 2c-microwave absorbing material; The 2d-plastics; The 3-fire door; 3a-fire door groove; The 4-door-hinge.
A: the degree of depth of furnace chamber groove; B: the degree of depth of fire door groove; H: the thickness of microwave absorbing chamber
A shown in Fig. 2 is maximum, and B is zero; A shown in Fig. 3 is zero, and B is maximum.
Five, the specific embodiment
As shown in Figure 1, the structure of the door for microwave oven of this band microwave absorbing chamber is similar to existing door for microwave oven, be characterized in: do a groove respectively to hold microwave absorbing chamber 2 at fire door 3 medial surfaces and furnace chamber 1 front, the degree of depth A of the depth B of fire door groove 3a and furnace chamber groove 1a can change between the thickness H of microwave absorbing chamber 2 zero, and their sums equate with the thickness of microwave absorbing chamber, be A+B=H, as shown in Figures 2 and 3, wherein, for the furnace chamber depth of groove is done maximum, fire door is not made the schematic diagram of groove among Fig. 2; For the fire door groove 3a degree of depth is done maximum, furnace chamber is not made the schematic diagram of groove among Fig. 3, can determine to adopt according to actual conditions.
During micro-wave oven work, fire door 3 closes, as shown in Figures 2 and 3, the G tee section of microwave absorbing chamber 2 has drawn among the figure, arrow is represented the direction of microwave, leak microwave at first by the slit between fire door 3 and the furnace chamber boss 1a, because the direct projection of microwave, microwave will be directly enters microwave absorbing chamber 2 by the rectangular opening 2a of microwave absorbing chamber 2 sides, and reflection is passed plastic layer 2d and is absorbed fully by the microwave absorbing material 2c of inside within it,, and can not turn slot leakage by furnace chamber 1 and microwave absorbing chamber 2 again outside stove.After the long-term use of micro-wave oven, because the slit that wearing and tearing fire door 3 and furnace chamber are 1 is strengthened, and this moment is because the rectangular opening 2a of microwave absorbing chamber 2 has certain width, after the slit is strengthened, the leakage microwave still can enter microwave absorbing chamber 2 smoothly and be absorbed, and can not leak into stove and injure the user outward.
