Technical Field

[0001] The present invention relates to the technical field of compressors, and particularly relates to a housing assembly, a compressor and an air conditioner. Background Art

[0002] A compressor is an important component of an air conditioner. The compressor plays a role in compressing and driving a refrigerant in a refrigerant circuit. The compressor is generally installed inside the outdoor unit of the air conditioner. The compressor extracts and compresses the refrigerant from a low-pressure area and then sends it into a condenser. By dissipating heat through the condenser, the refrigerant is changed from a gaseous state to a liquid state.

[0003] In the related art, temperature sensors are provided on the compressors of some outdoor units of air conditioners. However, the installation structure of the temperature sensors is not firm, and the temperature sensors are prone to looseness. As a result, the detected temperature data is distorted. The electronic control system of the air conditioner controls the compressor based on the temperature data detected by the temperature sensor, and may not make a protection action in time, resulting in failure conditions such as pump body wear and motor demagnetization of the compressor.

[0037] In the description of the present invention, if the first and second are described only for the purpose of distinguishing technical features, they should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0039] An air conditioner, that is, an air conditioner, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the indoor environment air in a building. Generally, it includes several major parts such as a cold source / heat source device, a cold and heat medium distribution system, a terminal device, and other auxiliary devices. It mainly includes a refrigeration host, a water pump, a fan, and a pipeline system. The terminal device is responsible for using the cold and heat transferred to specifically process the air state so that the air parameters of the target environment reach the set target.

[0040] In the related art, most air conditioners use a compressor as the power source of the refrigerant. A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. The compressor sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses the refrigerant gas, outputs high-temperature and high-pressure refrigerant gas, and provides power for the circulation of the refrigerant, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).

[0041] To avoid the operating temperature of the compressor exceeding the limit, resulting in failure conditions such as pump body wear and motor demagnetization of the compressor, the electronic control system of the air conditioner usually controls the compressor based on temperature data, and the temperature data comes from a temperature sensor installed on the outer wall of the compressor. However, the installation structure of the temperature sensor is not firm, and the temperature sensor is prone to looseness, resulting in distorted temperature measurement data, which is not conducive to protecting the compressor.

[0042] As Figures 1 to 4 shown, an embodiment of the first aspect of the present invention provides a housing assembly applied to a compressor. The compressor generally has a closed housing 100, and both the motor and the compression mechanism are arranged inside the housing 100. The exhaust pipe 110 of the compressor is arranged on the housing 100, and the compressed high-temperature and high-pressure refrigerant gas is discharged through the exhaust pipe 110.

[0043] It can be understood that, in order to accurately detect the temperature of the housing 100 to monitor the operating state of the compressor, a temperature sensor 200 is arranged on the outer wall of the housing 100. As Figure 8 shown, the temperature sensor 200 is cylindrical. The temperature sensor 200 needs to be closely attached to the outer wall of the housing 100 and in close contact to accurately measure the temperature of the housing 100. Therefore, a fixing bracket 300 is connected to the housing 100 to limit the temperature sensor 200.

[0044] As Figure 2 shown, the fixing bracket 300 includes a fixing part 310 covering the temperature sensor 200 and a connecting part 320. The connecting part 320 is used for fixedly connecting the housing 100. There are two connecting parts 320, and the two connecting parts 320 are located on both sides of the fixing part 310, so that the relative position between the fixing part 310 and the housing 100 is fixed.

[0045] The fixing part 310 includes a top plate 311 and two side plates 312. The two side plates 312 are distributed on both sides of the top plate 311, that is, the side plates 312 serve as the connecting structure between the top plate 311 and the connecting part 320. The two side plates 312 are inclined, and the angle between the side plates 312 and the top plate 311 is an obtuse angle. It can be understood that the top plate 311 and the two side plates 312 are similar to three sides of a trapezoid, and the installation cavity 301 surrounded by the top plate 311, the two side plates 312 and the housing 100 is generally trapezoidal.

[0046] In addition, referring to Figure 3 and Figure 4, the top plate 311 is provided with an opening groove 3112, and the opening groove 3112 is located at one end away from the inlet end. The opening groove 3112 is also oriented in the direction away from the inlet end, and deviates from the center line of the top plate 311, that is, the opening groove 3112 is located at the edge of the top plate 311. By providing the opening groove 3112, the elasticity of the top plate 311 is increased, and the top plate 311 applies pressure to the temperature sensor 200 through the restoring force of the elastic deformation. The opening groove 3112 is not on the center line of the top plate 311, and the deformation of the top plate 311 is offset to the edge of the opening groove 3112, while the deformation of the position where the top plate 311 contacts the temperature sensor 200 is small, which is conducive to applying a more stable pressure to the temperature sensor 200, and reducing the risk of the temperature sensor 200 loosening during the operation of the compressor.

[0047] During assembly, the temperature sensor 200 is inserted into the installation cavity 301, and the temperature sensor 200 contacts the top plate 311, the two side plates 312 and the housing 100 at the same time. The position where the two side plates 312 contact the temperature sensor 200 is higher than the axis of the temperature sensor 200. Figure 2 As shown, the top plate 311 and the two side plates 312 of the fixing part 310 both apply pressure to the temperature sensor 200. The force F1 applied by the top plate 311 is directed toward the housing 100, so that the temperature sensor 200 is closely attached to the outer wall of the housing 100. The force F2 applied by the two side plates 312 is symmetrical, and the resultant force of the two forces F2 is also directed toward the housing 100, so that the temperature sensor 200 is also closely attached to the outer wall of the housing 100. The opening groove 3112 provides elastic deformation for the top plate 311, and the reset force of the elastic deformation is used to act on the temperature sensor 200. The temperature sensor 200 is restricted by the top plate 311 and the two side plates 312, so that the temperature sensor 200 maintains close contact with the housing 100, and the temperature sensor 200 can effectively and accurately detect the temperature of the housing 100, and the measurement data is accurate and reliable. The fixing bracket 300 of the embodiment of the present invention eliminates the defect of the loose temperature sensor 200. The temperature sensor 200 can provide real-time feedback on the temperature of the housing 100, which is conducive to accurately controlling the operation of the compressor, preventing the compressor from exceeding the operating temperature limit, and avoiding failure conditions such as pump body wear and motor demagnetization.

[0048] It is understandable that if Figure 1 As shown, since the exhaust pipe 110 is used to discharge high-temperature and high-pressure refrigerant gas, the temperature at the location of the exhaust pipe 110 is relatively high. Arranging the connection between the temperature sensor 200 and the shell 100 close to the exhaust pipe 110 can detect more accurate data and help protect the compressor.

[0049] It can be understood that the fixing part 310 has elasticity and can position the temperature sensor 200. The fixing part 310 can be made of an elastic material, such as copper alloy, or the fixing part 310 has a structure that can elastically deform, as long as the fixing part 310 can limit the temperature sensor 200.

[0050] Referring to Figure 3 , it can be understood that taking the axial direction of the temperature sensor 200 as the length direction of the top plate 311, the direction perpendicular to the length direction is the width direction. In order to make the opening groove 3112 deviate from the temperature sensor 200, the width dimension of the opening groove 3112 is set to be less than half of the width dimension of the top plate 311. Among them, it is a better solution that the width dimension of the opening groove 3112 is one-fifth of the width dimension of the top plate 311. The top plate 311 retains a large area, which is beneficial to applying pressure to the temperature sensor 200.

[0051] Referring to Figure 3 , it can be understood that there is a gap reserved between the opening groove 3112 and the flared opening 313, so that at least a part of the fixing part 310 is complete. The complete part of the top plate 311 and the two side plates 312 apply pressure to the temperature sensor 200, which is beneficial to fixing the temperature sensor 200.

[0052] It can be understood that one end of the fixing bracket 300 where the temperature sensor 200 is inserted is defined as the inlet end. The temperature sensor 200 is inserted into the installation cavity 301 from the inlet end. Usually, the inlet end has a larger cross-sectional area to facilitate the insertion of the temperature sensor 200. Referring to Figure 5 and Figure 6 , in order to provide sufficient limitation, an arc-shaped arch 3111 can be set on the top plate 311 at the inlet end. As Figure 6 shown, the arc-shaped arch 3111 is an arc-shaped convex structure, and the arc-shaped arch 3111 faces the installation cavity 301. When the temperature sensor 200 is inserted into the installation cavity 301, the arc-shaped arch 3111 abuts against the temperature sensor 200. It can be understood that the structure of the arc-shaped arch 3111 has elasticity and generates a small elastic deformation when contacting the temperature sensor 200. According to the principle of reaction force, the arc-shaped arch 3111 applies a force towards the housing 100 to the temperature sensor 200, prompting the temperature sensor 200 to closely adhere to the outer wall of the housing 100.

[0053] It can be understood that the arc-shaped arch 3111 can be set only at the inlet end, or the arc-shaped arch 3111 extends along the axial direction of the temperature sensor 200, or along the axial direction of the temperature sensor 200, multiple arc-shaped arches 3111 are set on the top plate 311, all of which can meet the requirements of limiting the temperature sensor 200.

[0054] It can be understood that the installation cavity 301 can be set as a gradually shrinking cone, that is, in the axial direction of the temperature sensor 200, the installation cavity 301 gradually shrinks, and the inlet end is located at the larger end to facilitate the installation of the temperature sensor 200. The size of the large end of the installation cavity 301 can be set to be larger than that of the temperature sensor 200, and the size of the small end of the installation cavity 301 can be set to be smaller than that of the temperature sensor 200. Considering the three trapezoidal sides of the top plate 311 and the two side plates 312, the cross-section of the installation cavity 301 is similar to a trapezoid. Therefore, the width of the small end of the installation cavity 301 can be less than the diameter of the temperature sensor 200, or the height of the small end of the installation cavity 301 can be less than the diameter of the temperature sensor 200, or both the width and height of the small end of the installation cavity 301 can be less than the diameter of the temperature sensor 200. The opening groove 3112 provides elastic deformation for the fixing part 310 and can limit the temperature sensor 200. When the temperature sensor 200 is installed in the installation cavity 301, the gradually shrinking installation cavity 301 limits the temperature sensor 200, and the fixing part 310 exerts pressure on the temperature sensor 200, making the temperature sensor 200 closely adhere to the outer wall of the housing 100, so that the temperature sensor 200 is in close fit with the housing 100, and the temperature of the housing 100 can be measured accurately and in real time. Moreover, the small end of the installation cavity 301 can prevent the temperature sensor 200 from passing through and helps to accurately position it.

[0055] It can be understood that the small end of the installation cavity 301 can also be set to match the cross-sectional area of the temperature sensor 200. The temperature sensor 200 can be completely placed in the installation cavity 301, or a part of the temperature sensor 200 can protrude out of the installation cavity 301. The fixing part 310 is used to limit the temperature sensor 200, so that the temperature sensor 200 remains in contact with the housing 100, and the temperature of the housing 100 can be detected accurately and in real time.

[0056] It can be understood that the small end of the installation cavity 301 can also be set to be slightly larger than the temperature sensor 200, and a part of the temperature sensor 200 protrudes out of the installation cavity 301.

[0057] It can be understood that the structure for realizing the gradual shrinkage of the installation cavity 301 is that the top plate 311 is arranged obliquely. In the axial direction of the temperature sensor 200, along the direction away from the inlet end, the top plate 311 inclines towards the housing 100, that is, the distance between the top plate 311 and the housing 100 gradually decreases, making the installation cavity 301 present a gradually shrinking structure. In addition, the inclined top plate 311 exerts a force on the temperature sensor 200 towards the housing 100, prompting the temperature sensor 200 to closely adhere to the outer wall of the housing 100.

[0058] It can be understood that the structure for realizing the gradual contraction of the installation cavity 301 is that the two side plates 312 gradually converge. In the axial direction of the temperature sensor 200, along the direction away from the inlet end, the distance between the two side plates 312 gradually decreases, so that the installation cavity 301 presents a gradually contracting structure. In addition, with the above structure, the two side plates 312 exert greater force on the temperature sensor 200, which helps to make the temperature sensor 200 closely adhere to the outer wall of the housing 100, and the two side plates 312 also cooperate to clamp the temperature sensor 200 to prevent the temperature sensor 200 from falling out of the installation cavity 301.

[0059] Of course, the structure of the top plate 311 being inclined and the two side plates 312 gradually converging can also be adopted simultaneously to realize the gradual contraction of the installation cavity 301. When the temperature sensor 200 is installed in the installation cavity 301, both the top plate 311 and the two side plates 312 exert pressure on the temperature sensor 200, so that the temperature sensor 200 closely adheres to the outer wall of the housing 100, and the two side plates 312 also cooperate to clamp the temperature sensor 200 to prevent the temperature sensor 200 from falling out of the installation cavity 301.

[0060] Refer to Figure 3 , it can be understood that the fixing bracket 300 is provided with a flared opening 313, and the cross-section of the flared opening 313 is larger than that of the temperature sensor 200. The flared opening 313 is the inlet end, serving as the inlet of the installation cavity 301, that is, the temperature sensor 200 is inserted into the installation cavity 301 from the flared opening 313. The flared opening 313 is used to expand the entering space, facilitating the installation of the temperature sensor 200, and the inner wall surface of the flared opening 313 is trumpet-shaped, which can prompt the temperature sensor 200 to be centered and accurately enter the installation cavity 301, improving the installation efficiency.

[0061] It can be understood that considering that the fixing bracket 300 is used to fix the temperature sensor 200, and the fixing part 310 needs to exert pressure on the temperature sensor 200 to prompt the temperature sensor 200 to contact the outer wall of the housing 100, it is set that in the axial direction of the temperature sensor 200, the length occupied by the flared opening 313 should be less than one-third of the fixing bracket 300. It is a better choice that the length of the flared opening 313 is one-tenth of the fixing bracket 300, and the fixing part 310 has nine-tenths of the length to exert pressure on the temperature sensor 200, which is sufficient to limit the temperature sensor 200.

[0062] It can be understood that the length of the effective temperature sensing region of the temperature sensor 200 along the axis is the effective temperature sensing length, and the effective temperature sensing length is fixed. Setting the length of the fixing part 310 to be less than the effective temperature sensing length is beneficial to observing whether the temperature sensor 200 is in close contact with the housing 100 and reducing the resistance during the assembly process.

[0063] Refer to Figure 8It is understandable that the temperature sensor 200 is usually externally mounted with a thermistor sleeve 210. Considering that the position of the temperature sensor 200 to be installed in the installation cavity 301 needs to be accurately positioned, the cross section of the flared opening 313 is set to be smaller than the cross section of the thermistor sleeve 210, that is, the thermistor sleeve 210 cannot enter the flared opening 313, which plays a role of limiting. When assembling the temperature sensor 200, the thermistor sleeve 210 is used to abut against the flared opening 313 as a positioning to accurately limit the installation depth of the temperature sensor 200.

[0064] It is understandable that in order to limit the length of the temperature sensor 200 installed in the installation cavity 301, other structural forms can also be used. For example, the end of the fixed bracket 300 opposite to the expansion opening 313 is set as a closed structure. When the temperature sensor 200 is installed in the installation cavity 301, it can be directly inserted to the bottom, which is simple and convenient.

[0065] Alternatively, a limiting structure such as a limiting ring is provided on the inner wall of the fixing portion 310 , and the temperature sensor 200 is installed into the installation cavity 301 until the temperature sensor 200 abuts against the limiting ring.

[0066] Alternatively, a pressing piece 314 is provided on the end of the side plate 312 away from the flared opening 313, and the pressing piece 314 extends along the axial direction of the temperature sensor 200. When the temperature sensor 200 is installed in the installation cavity 301, it can be determined whether the temperature sensor 200 is installed in place by observing the relative position of the temperature sensor 200 and the pressing piece 314. The two pressing pieces 314 can also apply a clamping force to the temperature sensor 200 to fix the temperature sensor 200 and prevent it from escaping from the installation cavity 301.

[0067] Reference Figure 3 It can be understood that two welding spots 321 are arranged on each connection part 320, and the fixing bracket 300 has a total of four welding spots 321. The welding spots 321 are used to cooperate with the shell 100 for welding, and the welding method is resistance welding to fix the connection part 320 on the outer wall of the shell 100. Resistance welding refers to a method of using the resistance heat generated by the current passing through the weldment and the contact point as a heat source to locally heat the weldment, heat the workpiece to a molten or plastic state at the contact surface and adjacent areas of the workpiece, and pressurize the welding at the same time. During welding, no filler metal is required, the productivity is high, the deformation of the weldment is small, and automation is easy to achieve. In order to accurately define the welding area, two welding spots 321 are arranged on each connection part 320, such as Figure 4 As shown, the welding point 321 is a convex bump facing the housing 100, which is combined with the resistance welding process to improve the welding efficiency.

[0068] It is understandable that the connection part 320 can also be installed on the housing 100 through a fixing member, for example, the connection part 320 is fixedly connected to the housing 100 by screws. The connection part 320 can also be adhered to the housing 100 by glue to achieve fixation.

[0069] The compressor proposed in the embodiment of the second aspect of the present invention includes the housing assembly of the embodiment of the first aspect. A fixing bracket 300 is connected to the housing 100 of the compressor. The fixing portion 310 of the fixing bracket 300 includes a top plate 311 and two side plates 312. The two side plates 312 are distributed on both sides of the top plate 311. The two side plates 312 are arranged obliquely, and the angle between the side plate 312 and the top plate 311 is an obtuse angle. It can be understood that the top plate 311 and the two side plates 312 are similar to three sides of a trapezoid, so that the cross-section of the installation cavity 301 surrounded by the top plate 311, the two side plates 312 and the housing 100 is trapezoidal.

[0070] During assembly, the temperature sensor 200 is inserted into the installation cavity 301. The temperature sensor 200 contacts the top plate 311, the two side plates 312 and the housing 100 at the same time. The positions where the two side plates 312 contact the temperature sensor 200 are higher than the axis of the temperature sensor 200. As Figure 2 shown, both the top plate 311 and the two side plates 312 of the fixing portion 310 apply pressure to the temperature sensor 200. The force F1 applied by the top plate 311 is towards the housing 100, so that the temperature sensor 200 is closely attached to the outer wall of the housing 100. The forces F2 applied by the two side plates 312 are symmetrical, and the resultant force of the two forces F2 is also towards the housing 100, which also makes the temperature sensor 200 closely attached to the outer wall of the housing 100. The opening groove 3112 provides elastic deformation for the top plate 311, and the restoring force of the elastic deformation acts on the temperature sensor 200. Through the restriction of the temperature sensor 200 by the top plate 311 and the two side plates 312, the temperature sensor 200 is kept in close contact with the housing 100, and the temperature sensor 200 can effectively measure the temperature of the housing 100, and the measurement data is accurate and reliable. The fixing bracket 300 of the embodiment of the present invention eliminates the defect of loosening of the temperature sensor 200, ensures that the temperature sensor 200 accurately detects the temperature of the housing 100, the temperature sensor 200 can real-time feedback the temperature of the housing 100, which is beneficial to accurately control the operation of the compressor, prevent the compressor from exceeding the operating temperature limit, and avoid failure conditions such as pump body wear and motor demagnetization.
