Abstract
The present invention discloses a belt pulley of an indoor machine of a pipe-typed air conditioner; the indoor machine comprises a ventilating device, a belt pulley that is arranged on the ventilating device and a motor that transfers the power to the ventilating device through a tooth-shaped belt; the inner wall of the belt pulley groove is provided with a tooth-shaped part that adapts to the tooth shape of the tooth-shaped belt. Since the inner wall of the belt pulley groove is provided with a tooth-shaped part that adapts to the tooth shape of the tooth-shaped belt, when the transmission is performed by the tooth-shaped belt, the belt can be effectively contacted with the belt pulley, thereby improving the transmission ratio.
Description
Technical field
The present invention relates to pipe type air conditioner, particularly relate to the belt pulley of pipe type indoor set of air conditioner.
Background technology
In the prior art, pipe type air conditioner generally comprises indoor set and off-premises station, wherein the flow direction according to wind path comprises air suction inlet, air-supply arrangement, heat exchanger and blow-off outlet successively in the housing of indoor set, and wherein air-supply arrangement is positioned at the wind path upstream of heat exchanger.Described pipe type air conditioner is when making warm or refrigerating operaton, indoor set sucks room air in the indoor set by suction inlet, pass through air-supply arrangement subsequently, then after over-heat-exchanger carries out the exchange of heat, blow out from the blow-off outlet of indoor set, thereby warm braw or cold wind are sent, reached the effect that system is warm or freeze.
Fig. 1 is the schematic diagram of indoor set of the pipe type air conditioner of prior art.As shown in the figure, in the prior art, pipe type air conditioner comprises off-premises station (not shown) and indoor set, wherein in the housing 1 of indoor set, be disposed with air suction inlet 2, air-supply arrangement 3, heat exchanger (not shown) and blow-off outlet (not shown) according to the wind path flow direction, wherein air-supply arrangement 3 is arranged on the wind path upstream of heat exchanger, and air suction inlet 2 is arranged on the rear of air-supply arrangement 3, and air sucks from the rear side of indoor set, from after flow into forward in the housing 1 of indoor set.And the below of air-supply arrangement 3 is by panel 4 closures.The belt pulley 6 of air-supply arrangement 3 and motor 5 carry out transmission by a belt.
Above-mentioned pipe type air conditioner is when making warm or refrigerating operaton, indoor set sucks air by suction inlet 2 from the rear of air-supply arrangement 3, through behind the air-supply arrangement, enter heat exchanger and carry out heat exchange, thereby warm braw or cold wind are flowed out from blow-off outlet, reach the effect that system is warm or freeze.
But as shown in Figure 2, the inwall 7 of the race of the belt pulley 6 of the indoor set of the pipe type air conditioner of prior art is smooth plane, when relying on the power of thread form V-belt transmission motor, owing to have skidding,, reduced the air-supply efficient of air-conditioning so exist certain gear ratio.
Summary of the invention
In order to address the above problem, to the object of the present invention is to provide a kind ofly on the race inwall of belt pulley, to be formed with toothed region, thereby can improve the belt pulley of the pipe type indoor set of air conditioner of motor gearratio.
In order to achieve the above object, technical scheme of the present invention is as follows:
A kind of belt pulley of pipe type indoor set of air conditioner, described indoor set comprises: air-supply arrangement, be installed in the belt pulley on the air-supply arrangement and transmit the motor of power by the thread form belt to air-supply arrangement, be formed with the toothed region that the profile of tooth with the thread form belt adapts on the race inwall of described belt pulley.
Above-mentioned toothed region evenly distributes on the race inwall of belt pulley, and corresponding one by one with the profile of tooth of thread form belt.
In addition, above-mentioned toothed region also can evenly distribute on the race inwall of belt pulley and setting at interval.
The belt pulley of pipe type indoor set of air conditioner of the present invention, owing on the race inwall of belt pulley, be formed with the toothed region that the profile of tooth with the thread form belt adapts, so when relying on the thread form belt to carry out transmission, belt can contact effectively with belt pulley, thereby improved gearratio, thereby improved the air-supply efficient of air-conditioner.
Description of drawings
1. Figure 1 shows that the structural representation of existing pipe type indoor set of air conditioner;
2. Figure 2 shows that the structural representation of the belt pulley of existing pipe type indoor set of air conditioner;
3. Figure 3 shows that the structural representation of the belt pulley of pipe type indoor set of air conditioner of the present invention.
Wherein:
1: housing 2: air suction inlet
3: air-supply arrangement 4: panel
5: motor 6,6 ': belt pulley
7,7 ': inwall 8: thread form portion
The specific embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to the belt pulley of pipe type indoor set of air conditioner of the present invention.
Figure 3 shows that the belt pulley 6 ' of pipe type indoor set of air conditioner of the present invention.As shown in the figure, be formed with the toothed region 8 that the profile of tooth with the thread form belt adapts on the race inwall 7 ' of belt pulley 6 ', toothed region 8 evenly is provided with around the periphery of the race inwall 7 ' of belt pulley 6 '.When machine operation, the toothed region 8 on the race inwall 7 ' of the tooth on the thread form belt and belt pulley 6 ' is corresponding one by one and be meshing with each other, and rotates thereby drive belt pulley 6 '.
In addition, above-mentioned toothed region 8 can also evenly distribute on the race inwall of belt pulley and be provided with at interval, that is: the toothed region 8 on the race inwall 7 ' of the tooth on the thread form belt and belt pulley 6 ' can not be corresponding one by one, so both can reduce difficulty of processing, can also save Master Cost.
The state that the toothed region of above-mentioned belt pulley is meshed with tooth on the belt has improved the gearratio of motor, thereby has improved the air-supply efficient of air-conditioner.
