Abstract

A radiation shield for kitchen household appliances relates to a radiation protection device, and can be used for all radiate kitchen appliances, in which, it can be avoid for microwave and electromagnetic radiation leakage to harm users. It is to put microwave cooker or electromagnetic cooker on a base with slot around to make radiation shield pressed into the slot forming a cavity, install a door hinged with the side at the front of opening of the radiation protection shield, on which, there is a observation window with an inside wall of radiation protection coating to make people look through the shield, open holes to distribute heat and vapor on the shield, open a wiring hole near the bottom edge on the back of shield to pull the wire of appliance out.

Description

Anti-radiation cover for household kitchen electric appliance

One, technical field

The present invention relates to a kind of electrical equipment shielding, it can be used for the various kitchen appliance that has radiation, especially microwave ovens or electromagnetic oven, puts it into the interior use of cover and can prevent microwave and electromagnetic radiation leakage injury user.

Two, background technology

Microwave oven is the electrical equipment that generally uses in the Modern Family kitchen, and microwave has certain harm to human body, thereby as the microwave 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.

Electromagnetic oven is Modern Family's kitchen appliance, especially cooks, hot water speed is fast, again without coal gas, brought convenience to people.And electromagnetic wave also has certain harm to human body, but present electromagnetic oven does not have protective device, and just reminds people will keep certain distance in use, and this is difficult to hold or be inconvenient to control concerning the people.

Three, summary of the invention

The objective of the invention is to solve above-mentioned the problems of the prior art, a kind of shielding is provided, it is put into kitchen appliance such as microwave oven or electromagnetic oven wherein, microwave or electromagnetic radiation leakage injury user in the time of can preventing to use.

Concrete scheme of the present invention is: microwave oven or electromagnetic oven are placed on the base, one all slots are arranged on this base, the cross section of slot is an infundibulate, it is the top broad, the consistency of thickness of a bottom and a radiation shield, and the shape of slot is consistent with radiation shield, makes radiation shield just in time be pressed into slot; And adorn one in the front openings of radiation shield and fan and the hinged cover door in its side, it is the observation window of antiradiation coating that an inwall is arranged on this, makes people can see situation in the cover; On radiation shield, hold diameter and less than the louvre of 3mm radiation can not leaked and heat steam can distribute, open a wire hole from the base, from then on the electric wire of electrical equipment can be pulled out outside the cover at the back side of radiation shield.

The present invention can also be at the inboard microwave absorbing chamber of placing an anti-microwave leakage in cover doorway, like this after the cover door closes, the cover door is tightly fitted with the radiation shield wall, the leakage rediation ripple through the slit between them after, will enter microwave absorbing chamber and be absorbed fully, and can not leak into outside the stove by the microwave absorbing material of inside.

The invention has the beneficial effects as follows: after putting into microwave oven or electromagnetic oven under the radiation shield, the microwave and the electromagnetic radiation of leaking will more effectively be kept off in radiation shield, it has added barrier one for existing equipment, minimizing is to user's harm, user's safety can be guaranteed for a long time, the harm of radiation needn't be worried.

Five, embodiment

The structure of embodiment 1 present embodiment anti-radiation cover for household kitchen electric appliance as depicted in figs. 1 and 2, it contains base 4 and radiation shield 9, one all slots 5 and an object placing platform 7 are arranged on base 4, wherein the cross section of slot 5 is an infundibulate, it is the top broad, the consistency of thickness of bottom and radiation shield 9, and the shape of slot 5 size is consistent with radiation shield 9, makes radiation shield 9 just in time be pressed into slot 5; Open the cover doorway in the front of radiation shield 9, adorn a fan and the hinged cover door 1 in its side, the inboard of cover door 1 have one with cover doorway boss 2 of the same size, the aspect ratio cover doorway height of object placing platform 7 can be taken out electrical equipment.

On cover door 1, adorn a glass and form observation window 3, on the glass inwall antiradiation coating is arranged, this coating is stayed the mesh of diameter less than 3mm, and on radiation shield 9, open the louvre 10 of a series of diameters less than 3mm, make electromagnetism involve microwave and do not leak, open a wire hole 8 from the base at the back side of radiation shield 9 from observation window 3 and louvre 10.

The material of above-mentioned base 4, radiation shield 9 and cover door 1 all adopts metal, and microwave and electromagnetic wave can not be penetrated, and antiradiation coating can be electromagnetic shielding absorbed layer or microwave absorbing layer, to realize that the electromagnetism that electrical equipment leaks is involved stopping of microwave.

As shown in Figure 2, electromagnetic oven 11 is placed on the object placing platform 7 of base 4 after, radiation shield 9 covers just in time will be pressed into slot 5 down, and electric wire can stretch out outer convenient use of cover by wire hole 8.Use that electromagnetic oven is cooked, during hot water, to cover door 1 and close, and make the cavity that forms a sealing in the cover, electromagnetic radiation can not shine human body, and the situation that the people can watch electromagnetic oven by the observation window 3 on the cover door 1, the hot gas that produces during work can distribute by louvre 10.

The structure of embodiment 2 present embodiment anti-radiation cover for household kitchen electric appliance as shown in figs. 1 and 3, it as different from Example 1: it can also be at the inboard microwave absorbing chamber 6 of placing an anti-microwave leakage in cover doorway.Microwave absorbing chamber 6 is rectangle frames, its cross section is the quadrangle that certain hem width is arranged, this quadrangle outer wall is metal level 6d, inwall is plastic layer 6b, between metal level and plastic layer, be full of microwave absorbing material 6c, and remove one section from the end forming an opening 6a belonging on the limit of inside casing, the side of end is prolonged form doorframe 6e.Microwave absorbing chamber 6 can weld or make section bar and be fixed on the radiation shield 9, and it is concordant with opening 6a with the binding face of doorframe 6e to make boss 2 be absorbed in microwave absorbing chamber 6 inside casing rear boss 2.

As shown in Figure 3, microwave oven 12 is placed on the object placing platform 7, like this after cover door 1 closes, boss 2 is tightly fitted with doorframe 6e, shown in arrow among the figure, leak microwave through the slit between them after because its direct projection will enter microwave absorbing chamber 6 by opening 6a, and reflection is passed plastic layer 6b and is absorbed fully by the microwave absorbing material 6c of inside within it, and can not leak into outside the stove.
