Abstract
The invention discloses a microwave oven doorframe provided with dual choking cavities, which comprises a doorframe body and a plurality of grooves that are formed through inward back turning and bending at the four edges of the periphery of the doorframe body, an outer side edge which forms the groove bends and protrudes inwards, and the groove is separated into two mutually communicated parts provided with two choking cavities. The microwave oven doorframe has the advantages that: a space surrounded by the grooves is separated into the two mutually communicated parts, thus leading microwave to generate dual choking which leads more microwave to return to an oven chamber, further effectively improving leakage problem, leading microwave to be absorbed by the oven body and remarkably reducing leakage.
Description
Technical field
The present invention relates to micro-wave oven, especially prevent the microwave oven door frame that has dual choke chamber of microwave leakage.
Background technology
Micro-wave oven is that a kind of electric current that utilizes produces microwave, and microwave irradiation in food, to the device that food heats, heat food is surperficial and inner simultaneously, can the multiple food of fast cooking.
In order to allow micro-wave oven food be cooked, need to regulate power output by user's requirement with multiple cooking methods.As the power output adjusting device, adopt knob usually.
As shown in Figure 1, the micro-wave oven 1 of conventional art has rectangular shape, and the outward appearance of its end face and the left and right sides is formed by shell 10.
The inside bottom surface of furnace chamber 20 is provided with the pallet 22 that can place food.Pallet 22 has disc-shape, allows food obtain uniform heating by rotation.The below of furnace chamber 20 is provided with pallet motor (figure slightly), is used for Rotary tray 22.
The positive right side of face of micro-wave oven 1 is formed with control panel 30, together forms the outward appearance of micro-wave oven 1 with door 12.Control panel 30 is provided with knob 40, various button and display 32, is used to regulate the work of micro-wave oven 1.
Though diagram at the rear of control panel 30, is not formed with the distribution chamber.The distribution chamber is used to install the various electronic units of micro-wave oven 1, is formed between shell 10 inboards and furnace chamber 20 lateral surfaces.
As shown in Figure 2, the door 12 of the micro-wave oven of prior art is made up of doorframe 2, the choker 11 and the door glass etc. that are installed on the doorframe 2, and doorframe 2 is made of a plurality of grooves 3 that play the choke chamber effect that doorframe main body 4 becomes with periphery quadrangle in doorframe main body 4.As shown in Figure 3, the frame that has a choke chamber that groove 3 turns back to the inside and is bent to form for the outer of doorframe main body 4, choker 11 is pressed on the groove 3, choker 11 is annotated part for plastics, and microwave oven door frame 2 is a metal material, owing to diffraction takes place the slit between choker 11 and the doorframe 2 easily the microwave leakage phenomenon takes place, as shown in Figure 3, dimetric groove 3 is single choke chamber, and the chokes effect is not strong, is easy to cause microwave leakage.
Summary of the invention
Technical problem to be solved by this invention is that a kind of microwave oven door frame that has dual choke chamber that prevents microwave leakage is provided.
For the technical solution problem, the technical solution used in the present invention is: a kind of microwave oven door frame that has dual choke chamber, comprise doorframe main body and a plurality of grooves that turn back to the inside and be bent to form on outer Thursday of the limit of doorframe main body, the inside warpage of outer side edges that forms groove protrudes, and groove is divided into two parts that are interconnected that have two choke chambers.
The invention has the beneficial effects as follows: groove surrounds the space and is divided into two parts that are interconnected, and promptly produces two choke chambers, makes microwave produce dual choke, dual choke makes microwave return the more of furnace chamber, effectively improved leakage problem, microwave is absorbed by body of heater, leaked obviously and reduce.
Description of drawings
Fig. 1 is a common microwave stove profile schematic diagram.
Fig. 2 is the stereogram at the microwave oven door frame back side of prior art.
Fig. 3 is the side view of a groove of microwave oven door frame of prior art.
Fig. 4 is the stereogram at the microwave oven door frame of the present invention back side.
Fig. 5 is the side view of a groove of microwave oven door frame of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
The operation principle of micro-wave oven of the present invention is identical with prior art, can be with reference to prior art, so no longer narration, the present invention and the difference of prior art are that the structure of microwave oven door frame is different, are described in detail below:
Shown in Fig. 4,5, the microwave oven door frame 42 that has dual choke chamber of the present invention, comprise doorframe main body 4 and a plurality of grooves 13 that turn back to the inside and be bent to form on outer Thursday of the limit of doorframe main body 4, its inside warpage of outer side edges that forms groove 13 protrudes, and groove 13 is divided into two parts that are interconnected that have two choke chambers 14,15.When microwave irradiation, two choke chambers 14,15 in the space that process groove 13 impales produce dual choke, make microwave return the more of furnace chamber, have effectively improved leakage problem, and microwave is absorbed by body of heater, leak obviously and reduce.
In sum, among the embodiment that content of the present invention is not confined to, the knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present invention, but this embodiment comprises within the scope of the present invention.
Claims (1)
1, a kind of microwave oven door frame that has dual choke chamber, comprise doorframe main body and a plurality of grooves that turn back to the inside and be bent to form on outer Thursday of the limit of doorframe main body, it is characterized in that the inside warpage of outer side edges that forms groove (13) protrudes, and is divided into groove (13) two parts that are interconnected that have two choke chambers.
