Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator noise prevention, in particular to a pipe fitting, a press chamber and an electrical appliance. Background Art

[0002] Currently, most refrigerators on the market use compression cycle refrigeration. A compressor is installed at the bottom of the refrigerator. There are two pipes on the compressor, which are responsible for inputting the refrigerant to be compressed into the compressor and outputting the refrigerant to be exhausted after compression. According to their functions, they are called return air connecting pipe and exhaust connecting pipe respectively.

[0003] When the refrigerator is running, the rotor inside the compressor rotates at high speed, which will cause the exhaust connection pipe and the return air connection pipe on the compressor to resonate, which has become one of the main sources of refrigerator noise. In the actual production process, heavy objects are usually added around the pipe to suppress the resonance of the pipe, but the effect is not good. Utility Model Content

[0004] The embodiments of the utility model provide a pipe fitting, a press chamber, and an electrical appliance, which can improve the technical problem of noise generated by resonance of the pipe fitting.

[0005] In a first aspect, an embodiment of the utility model provides a pipe fitting, which is applied to a press chamber, and the pipe fitting comprises:

[0006] A first tube body having a first coiled section;

[0007] The second tube body has a second winding section, and the second winding section is wound in parallel with the first winding section.

[0008] In the embodiments of the present application, the pipe body is coiled and two pipe bodies are arranged in parallel to change the shape and mass of the pipe body, thereby reducing the resonance generated by the pipe fitting.

[0009] In one embodiment, along the radial direction of the first winding segment and the second winding segment, both sides of the second winding segment abut against the first winding segment.

[0010] In the embodiment of the present application, by abutting both sides of the second winding section against the first winding section, the gap between the first winding section and the second winding section can be reduced, thereby avoiding vibration inside the first winding section and the second winding section, and at the same time making the structure between the first winding section and the second winding section tighter, thereby achieving the effect of reducing resonance.

[0011] In one embodiment, the second winding section and the first winding section are wound in parallel to form an elliptical cylindrical winding body, and the length ratio of the major axis to the minor axis of the winding body is 5:(6.5-7.5).

[0012] In one embodiment, the first tube body further includes a first connecting segment and a second connecting segment respectively disposed at two ends of the first winding segment, and the second tube body further includes a third connecting segment and a fourth connecting segment respectively disposed at two ends of the second winding segment.

The input end and the output end of the first tube body and the second tube body are arranged in parallel, which can further increase the stability between the first tube body and the second tube body, thereby achieving the effect of reducing resonance. At the same time, since the input end and the output end of the tube body are respectively located at the outside and the center of the winding section, the winding body is arranged in an elliptical cylinder, which can further increase the stability between the first tube body and the second tube body, thereby achieving the effect of reducing resonance.

[0016] In one embodiment, the first winding segment has a first surface facing away from the first connecting segment and the third connecting segment, the second winding segment has a second surface facing away from the second connecting segment and the fourth connecting segment, and the first surface is coplanar with the second surface.

[0017] In an embodiment of the present application, the first surface of the first winding segment and the second surface of the second winding segment are made coplanar, so that when the first winding segment and the second winding segment are placed on the bottom plate of the press chamber, the contact area is larger, thereby increasing their stability on the bottom plate of the press chamber, thereby achieving the effect of reducing resonance.

[0018] In one embodiment, the first connecting segment and the third connecting segment are at least partially parallel to the first surface, and the second connecting segment and the fourth connecting segment are at least partially parallel to the first surface.

[0019] In the embodiment of the present application, the parallel direction of the first connecting segment and the third connecting segment and the parallel direction of the second connecting segment and the fourth connecting segment are parallel to the first surface, which can further increase the stability between the first tube body and the second tube body, thereby achieving the effect of reducing resonance.

[0020] In one embodiment, the first tube body and the second tube body are at least partially fixedly connected.

[0021] In the embodiment of the present application, by fixedly connecting the first tube body and the second tube body, the gap between the first tube body and the second tube body can be further reduced, thereby reducing the vibration between the first tube body and the second tube body, and at the same time, the stability between the first tube body and the second tube body can be further increased, thereby achieving the effect of reducing resonance. In one embodiment, the first coiled section is fixedly connected to the second coiled section.

[0022] In the embodiments of the present application, by fixedly connecting the first winding section with the second winding section, the gap between the first tube body and the second tube body can be effectively reduced, thereby reducing the vibration between the first tube body and the second tube body. At the same time, the stability of the winding section can be effectively increased, thereby increasing the stability between the first tube body and the second tube body, thereby achieving the effect of reducing resonance.

[0023] In one embodiment, a fixing tape is wound around the surfaces of the first winding section and the second winding section.

[0024] In the embodiment of the present application, the adhesive tape is sticky and can effectively increase the stability of the coiled section.

[0025] In a second aspect, an embodiment of the utility model provides a press bin, comprising:

[0026] Press chamber body;

[0027] A compressor is arranged in the compressor chamber body;

[0028] The above-mentioned pipe fittings are arranged in the compressor chamber body, one end of the first pipe body is connected to the compressor for inputting the refrigerant to be compressed into the compressor, the other end of the first pipe body is used to input the refrigerant to be compressed, one end of the second pipe body is connected to the compressor for receiving the refrigerant compressed by the compressor, and the other end of the second pipe body is used to discharge the refrigerant compressed by the compressor.

[0029] In one embodiment, the first winding section and the second winding section are arranged on the bottom plate of the press chamber, and the first winding section and the second winding section are connected to the bottom plate of the press chamber.

[0030] In one embodiment, the first winding section and the second winding section are connected to the bottom plate of the press chamber through a viscous damping layer.

[0031] In the embodiment of the present application, by setting a viscous damping layer between the first winding section and the second winding section and the bottom plate of the compressor chamber, the vibration of the first winding section and the second winding section can be effectively weakened, thereby achieving the effect of reducing resonance. In the embodiment of the present application, the above-mentioned pipe fittings can effectively reduce the vibration of the pipe fittings caused by the vibration of the compressor, thereby reducing the noise generated by resonance. At the same time, the first pipe body and the second pipe body are arranged in parallel, and the temperature of the first pipe body can be increased by the second pipe body, reducing the content of liquid refrigerant returning to the compressor, thereby preventing the compressor from generating liquid hammer.

[0038] See also Figure 1 and Figure 2 An embodiment of the utility model provides a pipe fitting, which is applied to a press chamber, and the pipe fitting includes:

[0039] The first tube body 10 has a first coiled section 11;

[0040] The second tube body 20 has a second winding section 21 , and the second winding section 21 is wound in parallel with the first winding section 11 .

[0041] It can be understood that the winding shape of the first winding section 11 and the second winding section 21 is a spiral shape, which has a high rigidity, thereby achieving a vibration reduction effect.

[0042] In one embodiment, along the radial direction of the first winding segment 11 and the second winding segment 21 , both sides of the second winding segment 21 abut against the first winding segment 11 .

[0043] It can be understood that both sides of the second winding segment 21 are abutted against the first winding segment 11, that is, the first winding segment 11 and the second winding segment 21 are adjacently embedded and arranged, and the first winding segment 11 and the adjacent second winding segment 21 are in contact and connected, thereby effectively reducing the gap and vibration between the first winding segment 11 and the second winding segment 21.

Then, the upper and lower surfaces of the first winding segment 11 and the second winding segment 21 are parallel to the bottom plate of the press chamber. At the same time, the surfaces of the first winding segment 11 and the second winding segment 21 in contact with the bottom plate of the press chamber are coplanar, which can maximize the contact area between the first winding segment 11 and the second winding segment 21 and the bottom plate of the press chamber, thereby increasing the stability of the tube body.

[0052] In one embodiment, the first connecting segment 12 and the third connecting segment 22 are at least partially parallel to the first surface, and the second connecting segment 13 and the fourth connecting segment 23 are at least partially parallel to the first surface.

The way of wrapping the fixing tape 30 on the surface of the first winding section 11 and the second winding section 21 can be to wrap one circle of the fixing tape 30 on the surface of the first winding section 11 and the second winding section 21, or to wrap multiple circles of the fixing tape 30 on the surface of the first winding section 11 and the second winding section 21.

The other end of the second pipe body 20 is used to discharge the refrigerant compressed by the compressor.

[0064] It is understandable that the vibration of the compressor will cause the pipes connected to the compressor to vibrate. By adjusting the structure and quality of the pipes, the vibration caused by the vibration of the compressor to the pipes can be effectively offset.
