Abstract
The utility model relates to the technical field of air-conditioners, and provides an air-conditioner and an air return pipe thereof. The air return pipe comprises an air inlet section, an air outlet section and a V-shaped elbow section. The air inlet section is communicated with an exhaust port of a four-way valve in an outdoor unit of the air-conditioner, and the air outlet section is communicated with an air return port of a liquid storage pot in the outdoor unit of the air-conditioner. One end of the V-shaped elbow section is communicated with the air inlet section through a first elbow section, and the other end of the V-shaped elbow section is communicated with the air outlet section through a second elbow section. According to the air-conditioner and the air return pipe thereof, due to the fact that the V-shaped elbow section is connected between the air inlet section and the air outlet section of the air return pipe, the turning angle of refrigerant when the refrigerant flows in the V-shaped elbow section is greatly reduced, and therefore impact force of the refrigerant on the pipe wall is reduced; and due to the fact that the V-shaped elbow section is adopted, flexibility in overall arrangement of the air return pipe is enhanced, the air return pipe can be arranged in the mode of surrounding a compressor, thus, the air return pipe can have free variable in various directions, and vibration caused by work of the compressor can be greatly reduced.

In the utility model, because muffler is connected with " V " shape bend loss in the air inlet section and between giving vent to anger, like this, the angle that refrigerant changes in " V " shape bend loss process of flowing is reduced largely, thereby reduce refrigerant to the impact of tube wall, again because adopt " V " shape bend loss, the flexibility of the whole stringing of muffler is strengthened, make that the stringing tendency is around compressor, like this, muffler all has free variable in all directions, alleviates the vibrations that cause because of compressor operating greatly.
Description of drawings
Fig. 1 is the structural representation of the muffler that is used for air-conditioner that provides of the utility model.
Fig. 2 is muffler that the utility model the provides structural representation when being applied to air-conditioner outdoor unit.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, a kind of muffler 100 that the utility model provides is applied in the air-conditioner outdoor unit.It comprises air inlet section 110, the section of giving vent to anger 120 and " V " shape bend loss 130.V " shape bend loss 130 has two ends, is respectively termination 131 and termination 132.Wherein, termination 131 is communicated with air inlet section 110 by first bend loss 140, and termination 132 is communicated with the section of giving vent to anger 120 by second bend loss 150.
In the present embodiment, " V " shape opening angle α of " V " shape bend loss 130 is less than 180 °.Preferably, angle α scope is 20 °～40 °.When installing space is enough big, also can suitably increase angle.
In the present embodiment, first bend loss 140 comprises first straight length 141 and second straight length 142.One end of first straight length 141 is connected with the end bending of second straight length 142.The other end bending back of first straight length 141 is communicated with air inlet section 110, and the other end of second straight length 142 outwards is bent to form the first obtuse angle bending segment 1421 and is communicated with the termination 131 of " V " shape bend loss 130.
In the present embodiment, an end of second bend loss 150 is bent to form the second obtuse angle bending segment 151 and is communicated with the termination 132 of " V " shape bend loss 130, and the other end of second bend loss 150 bending back is communicated with the section of giving vent to anger 120.
Particularly, the other end of second bend loss 150 is bent to form right angle bending segment 152 and is communicated with the section of giving vent to anger 120.
In the present embodiment, preferably, the section of giving vent to anger 120 length are greater than 40mm.
And air inlet section 110 is preferentially selected straight length for use with return-air section 120.
With reference to Fig. 2, the structural representation when muffler is installed on air-conditioner outdoor unit in the present embodiment.Described air-conditioner comprises cross valve 200, compressor 300 and fluid reservoir 400, and above-mentioned muffler 100 is communicated between the return-air mouth 410 of the exhaust outlet of cross valve 200 and fluid reservoir 400.
Because muffler 100 is connected with " V " shape bend loss 130 between air inlet section 110 and the section of giving vent to anger 120, " V " shape opening angle α of " V " shape bend loss 130 is less than 180 °, like this, the angle that refrigerant changes in " V " shape bend loss 130 process of flowing is reduced largely, thereby reduce refrigerant to the impact of tube wall, again because adopt " V " shape bend loss 130, the flexibility of muffler 100 whole stringings is strengthened, make that the stringing tendency is around compressor, like this, muffler 100 all has free variable in all directions, alleviates the vibrations that cause because of compressor 300 work greatly.
And because being bent to form the second obtuse angle bending segment 151, an end of second bend loss 150 is communicated with the termination 132 of " V " shape bend loss 130, saved the space, and in order further to save the space, the obtuse angle scope of the second obtuse angle bending segment 151 is between 100 ° ~ 120 °.
And as can be seen from Figure, the return-air mouth 410 of fluid reservoir 400 straight up, and the section of giving vent to anger 120 is return-air mouth 410 straight lengths connected vertically therewith, equally the other end of second bend loss 150 is bent to form right angle bending segment 152 and is communicated with the section of giving vent to anger 120, also saves the space greatly.
And outwards being bent to form the first obtuse angle bending segment 1421, the other end of second straight length 142 is communicated with the termination 131 of " V " shape bend loss 130, the first obtuse angle bending segment 1421 herein is that formation is mild smooth excessive before " V " shape bend loss 130, thereby guarantees the smooth and easy circulation of refrigerant.
In the present embodiment, when mounted, the minimum point of " V " shape bend loss 130 is higher than the return-air mouth 410 place height of fluid reservoir 400, guarantees that like this refrigerant can flow to the fluid reservoir 400 from " V " shape bend loss 130 smoothly.
Same, for saving the space, guaranteeing the compactedness of stringing, in the present embodiment, first bend loss 140 comprises that first straight length 141 and second straight length 142 all are to come stringing along the tangential direction of compressor 300 outer walls.
Below only be preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
