1, technical field:
The utility model is a kind of micro-wave oven, belongs to the renovation technique of micro-wave oven.
2, background technology:
Existing micro-wave oven is to produce frequency electromagnetic waves by the magnetron in the micro-wave oven, and electromagnetic wave enters the furnace chamber that is placed with food through waveguide, and the food that is placed on the rotating glass dish of furnace chamber central authorities is heated.As shown in Figure 4, existing micro-wave oven all is that the waveguide mouth is opened on the sidewall or upper wall of furnace chamber, and microwave is by waveguide mouth microwave radiation in furnace chamber.The glass plate that is installed in furnace chamber lower wall center simultaneously constantly rotates, thereby the food that is placed on the glass plate is heated.It is uneven that microwave in this micro-wave oven furnace chamber distributes, and mainly the rotation by food improves heating uniformity.Simultaneously, glass plate is circular, and whole furnace chamber is a rectangle, needs the food of heating must be placed on the glass plate, has so just limited the volume that needs heat food, and the food of heating is fewer, and heating uniformity is poor, and efficient is low, and microwave oven turntable should not clean.
3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and a kind of even microwave distribution that makes in the furnace chamber is provided, and improves the micro-wave oven of the efficient of micro-wave oven simultaneously.
Structural representation of the present utility model as shown in Figure 1, the microwave generating apparatus that includes furnace chamber (1) and form by magnetron (2) and waveguide (3), wherein the waveguide mouth of waveguide (3) communicates with microwave entrance (10) on being arranged on furnace chamber (1) base plate, waveguide (3) is fixed on the lateral wall of furnace chamber (1), magnetron (2) is fixed on the waveguide (3), microwave entrance (10) locates to be provided with the microwave agitating device, and tray (8) places the top of microwave agitating device.
Above-mentioned microwave agitating device includes stirring motor (4), stirring motor bracing frame (5), shaft (6), stirring piece (7), stirring motor bracing frame (5) is fixed on the waveguide (3), stirring motor (4) is fixed on stirring motor bracing frame (5), stirring piece (7) is packed on the shaft (6), and shaft (6) is packed on the output shaft of stirring motor (4).
Above-mentioned waveguide (3) is fixed on the right-hand member lateral wall of furnace chamber (1).
Above-mentioned waveguide (3) is the waveguide of crooked 90 degree.
Above-mentioned stirring piece (7) by the screens spiral-lock on shaft (6).
Above-mentioned shaft (6) is inserted on the output shaft of stirring motor (4).
Above-mentioned stirring motor bracing frame (5) is fixed on the waveguide (3) by being welded on.
Above-mentioned tray (8) is made by micro-crystalline ceramic or glass.
Above-mentioned tray (8) is a rectangle, and it places in the furnace chamber (1) of cuboid.
Above-mentioned tray (8) is fixed with silica gel (9) and is reached edge sealing on the madial wall of furnace chamber (1).
The utility model is owing to adopt the version of no rotating disk, and it is evenly stirred microwave by agitating device, makes the interior even microwave distribution of furnace chamber, and the good uniformity of heat food improve the efficiency of heating surface of micro-wave oven simultaneously, and the furnace chamber inner structure is succinct, easy cleaning.In addition, tray of the present utility model is done rectangularity, it places in the furnace chamber of cuboid, the food that holds like this is more than the food that circular glass plate holds, the food that makes it each heating is many, and service efficiency height, the utility model are that a kind of design is ingenious, function admirable, convenient and practical micro-wave oven.

5, the specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, 2, 3, the microwave generating apparatus that includes furnace chamber 1 and form by magnetron 2 and waveguide 3, wherein the waveguide mouth of waveguide 3 communicates with microwave entrance 10 on being arranged on furnace chamber 1 base plate, waveguide 3 is fixed on the lateral wall of furnace chamber 1, magnetron 2 is fixed on the waveguide 3, microwave entrance 10 places are provided with the microwave agitating device, and tray 8 places the top of microwave agitating device.
Above-mentioned microwave agitating device includes stirring motor 4, stirring motor bracing frame 5, shaft 6, stirring piece 7, stirring motor bracing frame 5 is fixed on the waveguide 3, stirring motor 4 is fixed on stirring motor bracing frame 5, stirring piece 7 is packed on the shaft 6, and shaft 6 is packed on the output shaft of stirring motor 4.
In the present embodiment, above-mentioned waveguide 3 is fixed on the right-hand member lateral wall of furnace chamber 1.Above-mentioned waveguide 3 is the waveguide of crooked 90 degree.For ease of installing, on shaft 6, shaft 6 is inserted on the output shaft of stirring motor 4 above-mentioned stirring piece 7 by the screens spiral-lock, and stirring motor bracing frame 5 is fixed on the waveguide 3 by being welded on.
Because microwave energy penetrates micro-crystalline ceramic or glass well, so tray of the present utility model 8 is made by micro-crystalline ceramic or glass.Because the furnace chamber 1 of micro-wave oven is a cuboid, so tray of the present utility model 8 is also done rectangularity, it places in the furnace chamber 1 of cuboid, and the food that holds like this is more than the food that circular glass plate holds.
For steam in the process that prevents to heat enters the microwave agitating device of furnace chamber 1 bottom, the fixing and edge sealing of above-mentioned tray 8 usefulness silica gel 9 are on the madial wall of furnace chamber 1.
The utility model in use, the resonance wave that the waveguide 3 of crooked 90 degree sends magnetron 2 is transmitted to waveguide mouth 10 places of furnace chamber bottom, simultaneously, stirring motor 4 work, the drive stirring piece rotates, make the microwave that enters from the radiation of waveguide mouth change conduction orientation, thereby make the even microwave distribution in the furnace chamber, improve the efficient of complete machine.
