Description
Technical field
The invention belongs to the field that utilizes microwave heating equipment, particularly relate to a kind of roll wheel assembly, reduce the rotating disc support frame structure of the micro-wave oven of rotating disk vibrating noise with ball-type rolling and vibration-proof structure.
Background technology
Generally, micro-wave oven is the input according to electric current, allows the magnetron launched microwave, and (per second is about 2,450MHz) is heating source, upsets the device that Mo Chare between the molecule that the molecules align of food produces comes cooking food with high frequency waves.
Micro-wave oven is divided into: the home-use micro-wave oven that small-sized magnetron is installed; And the commerce micro-wave oven that large-scale or several magnetrons are installed.In addition, commercial main demand object with micro-wave oven is: the convenience store that frequency of utilization is higher, the restaurant that perhaps will finish food cooking at short notice.Therefore, with respect to home-use micro-wave oven, commercial will possess high relatively power with micro-wave oven.
Fig. 1 is the stereogram of general microwave oven.As shown in Figure 1, micro-wave oven comprises the body 1 that forms outward appearance, forms the furnace chamber 2 of cooking room, and the electric apparatus room of various electronic units is set.
The inside of furnace chamber 2 is that the inside of cooking room is provided with rotatably to placing the circular plate type rotating disk (not shown) of culinary art thing, so rotate each position of microwave energy uniform irradiation culinary art thing because of rotating disk during the cooking.Rotating disk is made by glass usually.
Fig. 2 is the rotating disc support frame stereogram; Fig. 3 is the rotating disc support frame vertical view; Fig. 4 is the A-A cutaway view; Fig. 5 is an A portion enlarged drawing.
Be provided with the rotating disc support frame 3 of supporting wheel in the furnace chamber, rotating disc support frame such as Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, rotating disc support frame is made of with the roll wheel assembly 6 that is connected with pole circular support body 4,3 poles 5 being connected on the support body circumference.Roll wheel assembly is made of the roller 8 that is formed on axle bumper 7, the roller shaft 9 on the pole and be installed on the roller shaft.Axle bumper, roller shaft and pole are integrally formed.Roller is columniform.
Come rotary turnplate by the electric rotating machine that is arranged on the furnace chamber inner underside (not shown), the rotating disc support frame that contacts with rotating disk is rotated by roll wheel assembly.
There are the following problems in the above-mentioned prior art: micro-wave oven is owing to use for a long time, and swill remains in the furnace chamber sometimes.If in furnace chamber, continue to use micro-wave oven under the state of food residual, swill water evaporates and become hard.And according to circumstances, owing to food hardens attached to the furnace chamber inner bottom surface, so the furnace chamber inner bottom surface becomes uneven.
At the roller of above-mentioned state bottom roller assembly, between rotating disk and furnace chamber inner bottom surface, be to be rolled by the rotation of rotating disk in the center with the roller shaft.At this moment, the roller of roll wheel assembly when food container is placed imbalance, can produce noise in furnace chamber.That is, contact with the furnace chamber inner bottom surface when roller is rotated in uneven bottom surface, produce noise.
And the periphery of noise and roller has confidential relation.The roller of prior art is a cylinder form, and according to the profile of Fig. 5, in order to improve the coefficient of friction that contacts with the furnace chamber inner bottom surface, the periphery of roller is formed flatly with a straight line.That is, with furnace chamber in the contact-making surface of the roller that contacts be designed to maximize the structure of the contact-making surface of roller.Because the periphery of roller is as above-mentioned, the easier food interior with remaining in furnace chamber contacts during the roll wheel assembly rotation, produces noise thus.
Therefore, cylindrical roller is continuous rolling on the furnace chamber inner bottom surface, is subjected to the influence of machining accuracy of roller own and furnace chamber inner bottom surface flatness, and glass plate can produce vibration in rolling process, has increased noise of microwave oven, and has increased the thermal deformation under the no-load condition.
Summary of the invention
The present invention provides a kind of roll wheel assembly with ball-type roller and vibration-proof structure for solving the technical problem that exists in the known technology, reduces the microwave oven turntable support frame structure of rotating disk vibrating noise.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The rotating disc support frame structure of micro-wave oven of the present invention comprises: support body, be connected pole and the roll wheel assembly that is connected with pole on the support body, its roll wheel assembly is provided with the spin seat of installing hole by the bottom; The elastic parts and the spin that are installed in the installing hole constitute, the sealing of installing hole one end, and the other end is open, and spin is connected with elastic parts, and spin is rolled in installing hole.
Described spin seat and pole are integrally formed.
Described installing hole diameter is corresponding with ball diameters.
The diameter of described installing hole open end is less than ball diameters.
Described elastic parts is made up of flexible member and baffle plate.
Described flexible member is made of the elasticity of plastics pad.
Described flexible member is made of spring.
Described spin is made by polytetrafluoroethylmaterial material.
Advantage and good effect that the present invention has are:
The rotating disc support frame structure of micro-wave oven of the present invention has adopted the ball-type roller, and is provided with elasticity of plastics pad vibration-proof structure, vibration when therefore having reduced dial rotation, reduce noise, and reduced the resonance probability of furnace chamber cavity, reduced the thermal deformation of furnace chamber cavity.
