Abstract
The invention relates to a clip for fixing a fan of an air conditioner. The clip is used for fixing the fan covered on a motor shaft; the fan fixing clip is of a circular shape and is circled by a steel plate strip. The middle part of one end part of the plate strip is cut with an incision along the length direction; the front ends of the extending parts of two sides of the incision are extended with two clipping pins to the outer side of a circular; two sides of the other end part of the plate strip are cut out along the length direction; and the front end of the extending part of the middle part is extended with one clipping pin to the outside of the circular. The extended clipping pin is clamped through a tong and is tightly clamped by force and the clip is retained on the front end of the motor shaft and fixes the fan. In the clip for fixing the fan, two end parts of the plate strip are extended with the clipping pins respectively; one end is extended with the clipping pin from two sides; the other end is extended with the clipping pin from the middle part; and when the clipping pin extending out from the front end of the clip is tightly clamped through the tong for fixing the fan, the clip has even stress and can not be ejected out so that the fan is convenient and safe to mount and detach.
Description
Technical field
The present invention relates to air conditioner, particularly relate to the air-conditioner fan fixing device.
Background technique
Air conditioner is a kind of electrical installations of room temperature being regulated and remained on the required situation of user, mainly is made of cooling cycle system and air circulation system.The air conditioning effect of air conditioner is finished jointly by cooling cycle system and air circulation system.Cooling cycle system comprises heat exchanger, compressor and throttling device.Air circulation system comprises fan and fan electromotor, inlets and putlets of ventilation and air filter.The cooling cycle system of air conditioner and the operation of air circulation system are controlled by electrical apparatus control system, the refrigerating/heating operation of control air conditioner, and carry out room temperature setting and wind speed control etc.
Under the control of electrical apparatus control system, refrigeration agent in the air conditioner cooling cycle system absorbs heat and heat release in the circulation of compression → condensation → expansion → evaporation, and carry out heat exchange with indoor air by the fan forced flow of air circulation system, to realize room temperature lowering or intensification, for people provide fresh, comfortable indoor air environment.
Air conditioner is broadly divided into package AC plant and detachable air conditioner.Package AC plant all is contained in all parts in the casing, is installed in indoor and outdoor jointing place, as is installed in the window air conditioner on the room window.The heat exchanger of vaporizer or condenser effect has been set respectively in the indoor and outdoors part.Refrigeration agent circulates in vaporizer and condenser by the conduit that connects between the indoor and outdoors and carries out the heat exchange circulation, moves with the refrigerating state operation that realizes air conditioner or the state that heats.
Detachable air conditioner is made up of indoor set and outdoor unit, and the heat exchanger of vaporizer or condenser effect has been set respectively in indoor set and outdoor unit.Refrigeration agent circulates in vaporizer and condenser by the conduit that connects between indoor set and the outdoor unit and carries out the heat exchange circulation, moves with the refrigerating state operation that realizes air conditioner or the state that heats.
Fan and fan electromotor are the chief components of air circulation system, are separately positioned on the vaporizer and the condenser next door of air conditioner.Fan forces indoor air constantly to enter air conditioner with heat exchanger carries out heat exchange under the drive of fan electromotor, and then flows back to indoorly, and the air circulation of so carrying out exchanges the air conditioning of realization room temperature lowering or intensification.
The fan of air conditioner mainly contains centrifugal cutter, axial-flow fan and axial fan.Centrifugal cutter is mainly adopted in the heat exchange of window air conditioner and cabinet-type air conditioner indoor evaporator, and axial-flow fan is mainly adopted in the heat exchange of wall-hanging air conditioner indoor evaporator, and air conditioner chamber's external condenser all adopts axial fan.
Fan is fixed on the motor shaft, and the high speed rotating forced-air circulation of driven by motor fan exchanges, and realizes the normal operation of air conditioner.Therefore, what the fan of high speed rotating must be firm is fixed on the motor shaft, and this also is one of problem of relatively paying attention to during air conditioner is installed.
Fig. 1 shows that the clamp that utilizes of prior art is fixed on state on the motor shaft to fan, the structure of the clamp that Fig. 2 displayed map 1 is related.As depicted in figs. 1 and 2, fan 1 is enclosed within on the motor shaft, and motor shaft passes from fan middle part circular hole, and clamp 2 is stuck on the motor shaft front end 3 that passes fan middle part circular hole.Clamp 2 is circular, by steel lath 4 coileds.Lath 4 two end part respectively along its length the side excise half, during lath coiled annulus, an end sides there is not cut-out to place the space of side, the other end excision, the lath two end part there are not the front end of cut-out to stretch out card base 5 to the annulus outside.
During with clamp 2 fan attachments 1, earlier circular clamp 2 is enclosed within on the motor shaft front end 3, clamps two card bases 5 and the firmly clamping of stretching out with pliers again, then the clamp 2 of steel lath is just confined on motor shaft front end 3, and fan 1 just is fixed on the motor shaft.
But, when utilizing above-mentioned clamp fan attachment, clamp two card bases that clamp stretches out with pliers, and two card bases not being subjected on the line of force at same, the clamp discontinuity is subjected to the clamp of pliers folder power effect to be easy to collapse and flies, and time-consuming, effort is gone back waste material.
Summary of the invention
When utilizing above-mentioned clamp fan attachment at prior art, exist clamp to be easy to collapse the problem that flies, the present invention releases the clamp of new structure, clamp lath one end stretches out card base from both sides, the other end stretches out card base from the centre, when clamping two card base fan attachments that clamp stretches out with pliers, clamp is stressed evenly, clamp can not occur and collapse and fly phenomenon.
Fixation clamp for air conditioner fan involved in the present invention is circular, by steel lath coiled.Gap has been cut in the centre along its length in one end of lath, and the front end of extension, gap both sides stretches out two card bases to the annulus outside; The other end of lath is along its length in the excision of bi-side part, and the front end of middle extension stretches out a card base to the annulus outside.
During with the clamp fan attachment, earlier circular clamp is enclosed within on the motor shaft front end, clamps three card bases that stretch out with pliers again, and firmly clamp, then the clamp of steel lath is just confined on the motor shaft front end, and fan just is fixed on the motor shaft.
Fan fixation clamp involved in the present invention, card base is stretched out at two end part respectively, one end stretches out card base from both sides, the other end stretches out card base from the centre, when the card base fan attachment that stretches out with pliers clamping clamp front end, clamp is stressed evenly, can not collapse to fly, and makes the very convenient and safety of installation and removal of fan.
