Abstract
The invention provides an air cooling refrigerator small in vibration and noise. The refrigerator comprises an air duct cover plate and a fan support fixedly installed on the air duct cover plate. A fan is fixedly installed between the air duct cover plate and the fan support, and a fan damping gasket is arranged between the fan and the fan support and/or between the fan and the air duct cover plate. Direct contact between the fan and the fan support and the air duct cover plate in the prior art is modified into indirect contact, refrigerator vibration is reduced by the damping of the fan damping gasket, and the noise is reduced.
Description
Technical field
The present invention relates to refrigeration plant, specifically, relate to a kind of refrigerator and fan electromotor fixture thereof.
Background technology
Refrigerator is as a kind of refrigeration plant, generally include the parts such as compressor, evaporimeter, by the vaporization of refrigerant material and the transformation between liquefaction, reach refrigeration, according to the difference of the interior type of cooling of refrigerator, refrigerator can be divided into two classes: cold air natural convection and cold air forced cyclic type.
So-called cold air natural convection: claim again direct-cooling type or have white refrigerator.Its refrigerating chamber is directly surrounded by evaporimeter, or in refrigerating chamber, has an evaporimeter, and refrigerating chamber top is provided with an evaporimeter more in addition, by the direct draw heat of evaporimeter, is lowered the temperature.This type of refrigerator structure is relatively simple, and power consumption is little, but temperature ineffectivity is slightly poor, uses relatively inconvenient.
So-called cold air forced cyclic type: claim again indirect-cooling (air-cooled) or frost-free refrigerator.In refrigerator, have a small fan being driven by blower fan, blower fan is connected by rotating shaft with fan, is also provided with air duct cover board between blower fan and fan, and blower fan is fixed on air duct cover board by fan supporter.Compressor start is after a period of time, and fan starting, delivers to refrigerating chamber and refrigerating chamber the cold on evaporimeter along the air channel designing, and such refrigerator adopts blower fan to force Air Flow in case, so the temperature inside the box is even, and cooling velocity is fast, easy to use.But also there are a lot of defects in such refrigerator, such as, due to the rotation of fan, to casing, bring larger vibration and noise.Existing blower tray directly adopts integrated design or adopts 2 straight line fixed forms with air duct cover board, and the constant intensity of front a kind of fixed form, compared with causing and the resonance of fixed structure greatly, brings larger vibration and noise; Rear a kind of fixed form easily causes flabellum initial start stage to be partial to vertical plane colliding other walls and damage and produce noise.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned technological deficiency, and a kind of vibration and the less wind cooling refrigerator of noise are provided.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of refrigerator, comprise air duct cover board, be fixedly mounted on the fan supporter on air duct cover board, between described air duct cover board and fan supporter, be installed with blower fan, between described blower fan and fan supporter and/or between described blower fan and air duct cover board, be provided with blower fan damping washer.
The present invention is by setting up blower fan damping washer stating between blower fan and fan supporter and/or between described blower fan and air duct cover board, change blower fan in prior art into mediate contact with direct contact the between fan supporter and air duct cover board, buffering minimizing refrigerator by fan shock-absorbing packing ring vibrates, and then reduces noise.
In order further to reduce fan vibration, at least one side of described blower fan damping washer is provided with salient point, and is provided with the one side and blower fan close contact of salient point.The design of salient point has reduced the contact-making surface between fan shock-absorbing packing ring and blower fan, makes fan shock-absorbing packing ring can absorb the more vibrations of consumption.
The round sheet structure that fan shock-absorbing packing ring of the present invention is hollow, is convenient to fan shaft and passes.
Because elastomeric material has very strong pliability, therefore, fan shock-absorbing packing ring of the present invention is made by elastomeric material.
Fan supporter of the present invention comprise with the compressing tablet of blower fan close contact and with the rigidly connected back shaft of compressing tablet, described back shaft end is provided with the axis hole passing for fixed axis or set bolt.This design has changed in the past by fan supporter and the integrated design of air duct cover board, but adopt fixed axis or set bolt that fan supporter is fixedly connected with air duct cover board, this structure can be good at reducing and even avoids and the resonance of parts around, therefore can greatly reduce the generation of noise.
Further, in order further to reduce vibration, the axis hole of described back shaft end is hatch frame, so-called opening design is that described axis hole is for being with axis hole jaggy herein, having broken original axis hole is complete moulding, opening design can absorb certain vibration, time less vibration is passed to the parts that other are attached thereto.
Further, in described axis hole, be provided with the fan supporter damping washer with fixed axis or set bolt close contact.Fan supporter damping washer makes to be connected softlyer between fixed axis or set bolt and fan supporter, has reduced the transmission of vibration, and then has also reduced the generation of noise.
In a word, the present invention is by setting up blower fan damping washer, fan supporter damping washer, by change fan supporter structure decrease generation and the transmission of vibration, and reduced to greatest extent noise, improved the result of use of refrigerator.
