Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.
[0038] 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.
[0039] In related technologies, most air conditioners use a compressor as the power source for 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).
[0040] 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.
[0041] As Figures 1 to 4 shown, an embodiment of the first aspect of the present invention proposes a housing assembly applied to a compressor. The compressor usually 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.
[0042] 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 only by close contact can the temperature of the housing 100 be accurately measured. Therefore, a fixing bracket 300 is connected to the housing 100 to limit the temperature sensor 200.
[0043] 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.
[0044] 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. The top plate 311, the two side plates 312, and the housing 100 together enclose an installation cavity 301.
[0045] 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 simultaneously. 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, the top plate 311 and the two side plates 312 of the fixing part 310 apply pressure to the temperature sensor 200. The force F1 applied by the top plate 311 is towards the housing 100, making the temperature sensor 200 closely attached to the outer wall of the housing 100. The forces F2 applied by the two side plates 312 are symmetric, 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. Through the restriction of the temperature sensor 200 by the top plate 311 and the two side plates 312, the temperature sensor 200 maintains 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 the 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.
[0046] It can be understood that, as Figure 1 shown, since the exhaust pipe 110 is used to discharge high-temperature and high-pressure refrigerant gas, the temperature at the position where the exhaust pipe 110 is located is relatively high. Arranging the connection position of the temperature sensor 200 and the housing 100 close to the exhaust pipe 110 can detect more accurate data, which helps to protect the compressor.
[0047] It can be understood that the fixing part 310 has elasticity to position the temperature sensor 200. It can be that the fixing part 310 is made of an elastic material, such as copper alloy, or the fixing part 310 has a structure that can elastically deform, as long as it can meet the requirement that the fixing part 310 limits the temperature sensor 200.
[0048] It can be understood that the end of the temperature sensor 200 inserted into the fixing bracket 300 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 provided on the top plate 311 at the inlet end, as Figure 6As 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 installed in the installation cavity 301, the arc-shaped arch 3111 abuts against the top surface of the temperature sensor 200. It can be understood that the mechanism of the arc-shaped arch 3111 has automatic elasticity and produces a small elastic deformation when contacting the temperature sensor 200. According to the principle of reaction force, the arc-shaped arch 3111 exerts a force towards the housing 100 on the temperature sensor 200, prompting the temperature sensor 200 to closely adhere to the outer wall of the housing 100.
[0049] It can be understood that the arc-shaped arch 3111 can be provided 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, and multiple arc-shaped arches 3111 are provided on the top plate 311, all of which can meet the requirements of limiting the temperature sensor 200.
[0050] It can be understood that the installation cavity 301 can be set to be conical, that is, along the axial direction of the temperature sensor 200, the installation cavity 301 gradually shrinks, and the inlet end is located at the larger end for the convenience of installing the temperature sensor 200. The size of the large end of the installation cavity 301 can be set to be larger than the temperature sensor 200, and the size of the small end of the installation cavity 301 can be set to be smaller than the temperature sensor 200. Considering the three trapezoidal sides of the top plate 311 and the two side plates 312 being similar to a trapezoid, 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 smaller than the diameter of the temperature sensor 200, or the height of the small end of the installation cavity 301 can be smaller 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 smaller than the diameter of the temperature sensor 200. The elastic deformation of the fixing part 310 is used to 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 closely attached to the housing 100, and the temperature of the housing 100 can be measured in real time and accurately. Moreover, the small end of the installation cavity 301 can prevent the temperature sensor 200 from passing through and helps to accurately position it.
[0051] 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 can detect the temperature of the housing 100 in real time and accurately.
[0052] 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 penetrates out of the installation cavity 301.
[0053] It can be understood that the structure for realizing the gradual contraction 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 contracting 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.
[0054] 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, making the installation cavity 301 present a gradually contracting structure. In addition, with the above structure, the two side plates 312 exert a greater force on the temperature sensor 200, which helps to prompt the temperature sensor 200 to 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 disengaging from the installation cavity 301.
[0055] Of course, the structure of the inclined arrangement of the top plate 311 and the gradual convergence of the two side plates 312 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, making 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 disengaging from the installation cavity 301.
[0056] Refer to Figure 3 , it can be understood that the fixing bracket 300 is provided with a flared opening 313, the cross-section of the flared opening 313 is larger than the cross-section of the temperature sensor 200, and the flared opening 313 is the inlet end and serves as the inlet of the installation cavity 301, that is, the temperature sensor 200 is installed 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 in a horn shape, which can prompt the temperature sensor 200 to be centered and accurately enter the installation cavity 301, improving the installation efficiency.
[0057] It can be understood that, considering that the fixing bracket 300 is used to fix the temperature sensor 200, and the fixing portion 310 needs to apply pressure to the temperature sensor 200 to force the temperature sensor 200 to contact the outer wall of the shell 100, it is set in the axial direction of the temperature sensor 200. The length occupied by the expansion 313 should be less than one-third of the fixing bracket 300, among which the length of the expansion 313 is one-tenth of the fixing bracket 300 is a better choice. The fixing portion 310 has nine-tenths of the length to apply pressure to the temperature sensor 200, which is sufficient to limit the temperature sensor 200.
[0058] It can be understood that the axial length of the effective temperature sensing area of the temperature sensor 200 is the effective temperature sensing length, and the effective temperature sensing length is fixed. Setting the length of the fixing portion 310 to be smaller than the effective temperature sensing length is beneficial for observing whether the temperature sensor 200 is in close contact with the housing 100 and reducing resistance during assembly.
[0059] Reference Figure 8 It 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.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] Reference Figure 3, It can be understood that two solder joints 321 are arranged on each connecting portion 320. There are a total of four solder joints 321 on the fixing bracket 300. The solder joints 321 are used to cooperate with the housing 100 for welding, and the welding method is resistance welding to fix the connecting portion 320 on the outer wall of the housing 100. Resistance welding refers to a method of using the resistance heat generated by the current passing through the workpiece and the contact area as the heat source to locally heat the workpiece, heating the workpiece to the melting or plastic state at the workpiece contact surface and adjacent areas, and at the same time applying pressure for welding. During welding, no filler metal is required, the productivity is high, the deformation of the workpiece is small, and it is easy to realize automation. In order to accurately define the welding area, two solder joints 321 are arranged on each connecting portion 320, as Figure 4 shown, the solder joint 321 is a convex bulge facing the housing 100, which cooperates with the resistance welding process to improve the welding efficiency.
[0064] It can be understood that the connecting portion 320 can also be installed on the housing 100 through a fixing member. For example, the connecting portion 320 is fixedly connected to the housing 100 by screws. The connecting portion 320 can also be adhered to the housing 100 with glue to achieve fixation.
[0065] 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. The 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 inclined. 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.
[0066] 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 2As shown, the top plate 311 and the two side plates 312 of the fixing part 310 apply pressure to the temperature sensor 200. The force F1 applied by the top plate 311 is towards the housing 100, causing the temperature sensor 200 to closely adhere to the outer wall of the housing 100. The forces F2 applied by the two side plates 312 are symmetric, and the resultant force of the two forces F2 is also towards the housing 100, which also causes the temperature sensor 200 to closely adhere to the outer wall of the housing 100. Through the restriction of the temperature sensor 200 by the top plate 311 and the two side plates 312, the temperature sensor 200 maintains 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 the loosening of the temperature sensor 200, ensures that the temperature sensor 200 accurately detects the temperature of the housing 100, and the temperature sensor 200 can timely feedback the temperature of the housing 100, which is beneficial 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.
