Description
Technical field
The present invention relates to window air conditioner, relate in particular to and a kind ofly can save the energy, reduce the gear transmission structure of the window air conditioner fan of indoor fan noise.
Background technology
Air conditioner is will be by the refrigerant of compressor, condenser, expansion gear and evaporimeter circulation, carry out heat exchange with air by evaporimeter after, interior space air is carried out a kind of device that changes in temperature are regulated.The structure of air conditioner comprises, off-premises station that constitutes by compressor, shrinkage machine and expansion gear and the indoor set that constitutes by fan and evaporimeter, off-premises station and indoor set between interconnect by coolant piping.
The kind of air conditioner is that the position that is provided with according to indoor set is divided into, uprightly be placed on indoor use the vertical type air conditioner, hang and to be installed in the wall air conditioner that uses on the indoor wall and to be installed in the ceiling board air conditioner machine that use at indoor top, the also promising saving interior space and be installed in the wall-through type air conditioner of window.
Consult shown in Figure 1ly, be existing a kind of window air conditioner structure, it comprises an one-piece box 1, and the both sides of one-piece box 1 are provided with and suck grid 7 and 7 ', are provided with dividing plate 2 in the one-piece box 1, and one-piece box is separated into indoor 3 and outside 4; Be provided with two fans 41 and 41 ', fan 41 and 41 ' drive motors 42 and 42 ', compressor 43 and in 4 spaces, outside and arrange the condenser 44 parallel with 41 ' with fan 41, this condenser 44 is the condenser of perpendicular shape, and be connected with the exhaust outlet of compressor 43, two fans 41 are connected with 42 ' outside rotating shaft with drive motors 42 respectively with 41 '; Be provided with two fans 31 and 31 ' and the one row evaporimeter 32 parallel with 31 ' in the space of indoor 3 with fan 31, this evaporimeter 32 is connected with the air entry of compressor 43, and two fans 31 are connected with 42 ' indoor rotating shaft with drive motors 42 respectively with 31 '; Be connected through the refrigerant pipe between condenser 44 and the evaporimeter 32, thereby form a circulatory system.
Consult shown in Figure 1, when existing window air conditioner machine is worked, when drive motors 42 and 42 ' energising, the both sides rotating shaft begins rotation, rotate simultaneously with indoor fan 31 and 31 ' with the outside fan 41 and 41 ' that the both sides rotating shaft is connected respectively, suction grid 7 and 7 ' the suction chamber outside 4 spaces of outdoor air by being located at one-piece box 1 both sides, room air is inboard 3 spaces of suction chamber then, under the effect of fan, the air in 4 spaces, outside carries out heat exchange by condenser 44 and to outdoor discharging, the air in 3 spaces, indoor carries out heat exchange by evaporimeter 32 and to indoor discharging, thereby reach the effect that room air and temperature are suitably regulated, contact with hot-air at evaporimeter 32 places and make the cold-producing medium of temperature increase, in passing through the process of condenser 44, rotation by outside 4 fans 41 and 41 ' drives, and is cooled off once more by the outdoor air that flows into the outside, so that continued circulation.
This project organization of existing window air conditioner machine, two fans 31 that its drive motors 42 and 42 ' drives respectively that indoor 3 is provided with by the both sides rotating shaft and 31 ' and two fans 41 and 41 ' of being provided with of outside 4 begin rotation.Because employed two powers of motor are identical, the rotating speed of indoor fan and outside fan is also identical.And the window air conditioner machine requires the exhaust air rate of outside fan to be far longer than the exhaust air rate of indoor fan when reality is used.Therefore, requirement for the exhaust air rate that satisfies the outside fan, when using, reality will adopt the powerful motor of the exhaust air rate that is applicable to the outside fan, this just causes when indoor fan exhaust amount is strengthened, the noise of indoor fan also increases thereupon, has influenced indoor working environment.And, because the heavy-duty motor that has used the exhaust air rate that is far longer than the indoor fan to require has also caused the waste of the energy.
