Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to a ceiling air conditioner. Background Art

[0002] Embedded ceiling air conditioners are mainly used in large venues such as offices, classrooms, and shopping malls. They have the advantages of small footprint and good cooling / heating effects, and are favored by users. The ceiling air conditioner includes a casing, which is provided with an air inlet and multiple air outlets. The casing is provided with an indoor heat exchanger and an indoor fan, so that air flows out from each air outlet of the ceiling air conditioner.

[0003] During the use of the ceiling unit, the moisture in the air will be cooled and form condensed water in the form of liquid beads on the surface of the indoor heat exchanger. The ceiling unit may include a water tray and a water pump. The water tray is arranged below the indoor heat exchanger to collect the condensed water dripping from the indoor heat exchanger. The water pump is used to discharge the condensed water in the water tray to the outside. When the water pump is running, it will vibrate and generate noise. In order to reduce vibration and noise, a shock absorber is generally installed on the fasteners for installing the water pump, and the shock absorber is used to separate the water pump from the base on which the water pump is installed.

[0004] In the related art, when installing a water pump, the fasteners and the shock absorbers are usually interference-fitted, which can easily cause resonance of the box, which is not conducive to reducing vibration noise. In addition, the existing shock absorbers have a simple structure. Due to the structural limitations of the shock absorbers, when the shock absorbers are offset during assembly, the noise caused is relatively large, which is not conducive to improving user experience. The existing shock absorbers have poor assembly consistency during assembly, resulting in inconsistent compression of the shock absorbers at each fastener, which cannot meet the requirements of the home improvement channel.

[0035] According to an embodiment of the present disclosure, in the axial direction of the shock absorber, the ratio of the length of the second through hole to the length of the shock absorber is 0.7-0.8.

[0038] According to an embodiment of the present disclosure, the annular clamping portion includes an annular clamping groove, and in the radial direction of the fastener, the single-sided clearance between the annular clamping groove and the mounting hole is a, 0<a, a≤0.25mm; this setting enables the clearance between the bracket and the shock absorber to match in the axial direction of the shock absorber, thereby reducing vibration noise.

[0039] According to an embodiment of the present disclosure, in the axial direction of the fastener, the single-side clearance between the annular groove and the mounting hole is b, 0<b, b≤0.15mm; this setting enables the clearance between the bracket and the shock absorber to match in the axial direction of the shock absorber, thereby reducing vibration noise.

[0065] The ceiling air conditioner performs the refrigeration cycle of the ceiling air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged. Among them, the ceiling air conditioner includes a ceiling unit (i.e., the indoor unit of the ceiling air conditioner) and an air conditioner outdoor unit (i.e., the outdoor unit of the air conditioner).

[0066] The utility model proposes a ceiling machine 100, which is shown below. Figures 1 to 20 The ceiling machine 100 is described, wherein: Figure 1 to Figure 3 1 is an appearance diagram of a ceiling unit 100. The ceiling unit 100 is an indoor unit part of a ceiling unit air conditioner. In addition, the ceiling unit air conditioner also includes an outdoor unit.

[0067] refer to Figure 1 In an exemplary embodiment of the ceiling machine 100 of the present invention, the ceiling machine 100 may include a housing 1. The housing 1 forms the overall appearance of the ceiling machine 100.

[0068] The housing 1 is in a cubic shape, and an installation cavity is formed inside the housing 1. The installation cavity is used to accommodate and fix various components in the ceiling machine 100, which can prevent foreign objects from colliding with various components in the housing 1, thereby improving the reliability of the ceiling machine 100 during transportation or installation.

[0069] In addition, the housing 1 can also isolate various internal components from external dust to improve the operating stability of the ceiling machine 100.

[0070] In some embodiments of the present application, the housing 1 may include an air inlet 13 .

[0071] The air inlet 13 is communicated with the installation cavity, and serves as an inlet for the external air of the housing 1 to flow in, allowing the indoor air to enter the installation cavity through the air inlet 13 .

[0072] In some embodiments of the present application, the housing 1 may include a plurality of air outlets 14 . The plurality of air outlets 14 are arranged around the air inlet 13 .

[0073] The air outlet 14 is communicated with the installation cavity, and serves as an outlet for the heat exchange airflow in the housing 1 to flow out, allowing the airflow in the installation cavity to flow out through a plurality of air outlets 14 .

[0074] In some embodiments of the present application, the housing 1 may include a box body 11 .

[0075] The box body 11 is suitable for being installed between the ceiling and the suspended ceiling. The bottom end of the box body 11 has an opening.

[0076] In some embodiments of the present application, the housing 1 may include a panel 12 .

[0077] The panel 12 is connected to the open end of the box body 11 to cover the opening of the box body 11, thereby shielding the box body 11. The panel 12 cooperates with the box body 11 to define and form the above-mentioned installation cavity.

[0078] The box body 11 is in the shape of a cube.

[0079] In some embodiments of the present application, an air inlet 13 and a plurality of air outlets 14 are opened on the panel 12 .

[0080] The air inlet 13 is arranged in the middle of the panel 12, and a plurality of air outlets 14 are arranged around the air inlet 13. This arrangement allows the ceiling machine 100 to take in air from the air inlet 13 in the middle of the panel 12 and blow it out toward the air outlets 14 on the surrounding sides when the ceiling machine 100 is in operation, so that the heat exchange airflow after heat exchange flows into the room from multiple directions, thereby increasing the air output of the ceiling machine 100.

[0081] In some embodiments of the present application, reference Figure 2 , Figure 4 The ceiling machine 100 proposed in the present invention is a four-air outlet ceiling machine, that is, an air inlet 13 and four air outlets 14 are provided on the panel 12 .

[0082] The air inlet 13 is a square air inlet 13 , and the four air outlets 14 are all arranged in a strip shape. The four air outlets 14 are arranged along the extension direction of the four sides of the panel 12 respectively.

[0083] In some embodiments of the present application, an air inlet grille 15 is provided at the air inlet 13 .

[0084] The air inlet grille 15 is connected to the casing 1 and is used to filter the indoor air entering the casing 1 to prevent larger impurities from entering the casing.

[0085] In some embodiments of the present application, the panel 12 is arranged in a square shape to match the open end of the box body 11 .

[0086] In some embodiments of the present application, the panel 12 may extend outside the box body 11 , thereby improving the aesthetics of the ceiling machine 100 and improving the integrity of the ceiling machine 100 .

[0087] When the ceiling machine 100 is installed, the panel 12 is roughly flush with the bottom surface of the ceiling, so that the panel 1212 and the ceiling form an integral structure. The panel 12 hides the box 11 between the ceiling and the ceiling, ensuring that the ceiling machine 100 can vent air while making the overall appearance better.

[0088] In some embodiments of the present application, the length dimension of the panel 12 may be greater than the length dimension of the opening of the box 11 , and the width dimension of the panel 12 may be greater than the width dimension of the opening of the box 11 , so that the panel 12 can completely cover the opening of the box 11 .

[0089] The panel 12 covers the opening at the bottom of the box 11 , which improves the aesthetics of the ceiling machine 100 . On the other hand, the bottom of the box 11 is fixed to the ceiling by being installed with the panel 12 .

[0090] In some embodiments of the present application, ends of the panel 12 extend beyond the box body 11, so that the connection area between the panel 12 and the ceiling is larger. The panel 12 is installed on the ceiling and the box body 11 respectively, further ensuring the assembly firmness of the ceiling machine 100.

[0091] In some embodiments of the present application, the ceiling machine 100 may include an indoor heat exchanger 2. The indoor heat exchanger 2 is disposed in the casing 1, and is used to perform heat exchange with the airflow in the casing 1.

[0092] In some embodiments of the present application, the ceiling machine 100 may include an indoor fan 3. The indoor fan 3 is disposed in the housing 1, and the indoor fan 3 is located in the middle of the installation cavity.

[0093] The indoor heat exchanger 2 is disposed outside the indoor fan 3 and is used to absorb heat from the indoor wind in the installation cavity or transfer heat to the indoor wind in the installation cavity.

[0094] The indoor fan 3 is disposed corresponding to the air inlet 13 to drive the indoor wind to enter the installation cavity through the air inlet 13 , so that the air flow can flow from the air inlet 13 to the air outlet 14 .

[0095] refer to Figure 5 In some embodiments of the present application, the indoor heat exchanger 2 is configured to surround the indoor fan 3 and is bent into a quadrilateral shape, and the indoor heat exchanger 2 is close to the air outlet 14 relative to the indoor fan 3.

[0096] When the ceiling machine 100 is in operation, driven by the indoor fan 3, the indoor air enters the installation cavity through the air inlet 13, the indoor air in the installation cavity flows through the indoor heat exchanger 2 for heat exchange, and the heat exchange air flows outwardly into the room through the air outlet 14, thereby enabling the ceiling machine to cool and heat, play a role in regulating the indoor temperature to achieve a comfortable temperature for the user.

[0097] The ceiling air conditioner has a refrigerant circuit that sequentially connects a compressor, a condenser, a throttling device, and an evaporator in an annular manner to circulate the refrigerant.

[0098] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The compressor is installed in the outdoor unit casing. The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state. The throttling device can be provided in the ceiling unit or the outdoor unit. The throttling device expands the liquid phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid phase refrigerant.

[0099] Among them, among both the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator.

[0100] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled.

[0101] The ceiling air conditioner includes a cooling mode and a heating mode. In the cooling mode, the indoor heat exchanger is an evaporator, the outdoor heat exchanger is a condenser, and the refrigerant circulates through the compressor, the outdoor heat exchanger, the throttling device, and the indoor heat exchanger in sequence. In the heating mode, the indoor heat exchanger is a condenser and the outdoor heat exchanger is an evaporator, and the refrigerant circulates through the compressor, the indoor heat exchanger, the throttling device, and the outdoor heat exchanger in sequence to achieve the air conditioning function.

[0102] In some other embodiments of this application, continue to refer to Figure 5 The ceiling machine 100 further includes an air guide ring 16. The air guide ring 16 is arranged corresponding to the air inlet 13, so that the airflow can enter the housing 1 through the air inlet more stably and accurately.

[0103] In some other embodiments of the present application, the box body 11 may include a chassis. The chassis is arranged opposite to the panel 12.

[0104] In some other embodiments of the present application, the indoor fan 3 may include a wind wheel, which is usually a centrifugal wind wheel 50 .

[0105] In some other embodiments of the present application, the indoor fan 3 may include a motor. The motor is arranged on the chassis, and the wind wheel is connected to the motor so that the motor drives the wind wheel to rotate.

[0106] In some embodiments of the present application, the ceiling machine 100 may include a water tray 4 .

[0107] refer to Figure 4 The water receiving pan 4 is close to the open end of the box body 11 relative to the indoor heat exchanger 2, and the water receiving pan 4 is connected to the open end of the box body 11.

[0108] The water receiving tray 4 is located below the indoor heat exchanger 2, so that it can receive and collect the condensed water falling from the indoor heat exchanger 2, thereby preventing the condensed water from being directly discharged into the room, thereby improving the safety and reliability of the operation of the ceiling machine 100.

[0109] It should be noted that in the cooling mode, when the air flow enters the casing 1 and exchanges heat with the indoor heat exchanger 2, the air flow with a higher temperature comes into contact with the indoor heat exchanger 2 with a lower temperature, and the water vapor in the air flow is liquefied, and forms liquid droplets of condensed water on the surface of the indoor heat exchanger 2. As the amount of condensed water gradually increases, the liquid droplets will gradually accumulate and become larger, and will begin to fall under the action of gravity, and then fall into the water receiving tray 4.

[0110] In some embodiments of the present application, the water receiving pan 4 is arranged in the installation cavity and located at the bottom of the installation cavity, and the bottom end of the indoor heat exchanger 2 abuts against the water receiving pan 4, so that the condensed water generated by the indoor heat exchanger 2 drips into the water receiving pan 4 for collection.

[0111] In some embodiments of the present application, the ceiling machine 100 may include a water pump assembly. The water pump assembly is disposed in the box body 11 and is spaced apart from the indoor heat exchanger 2.

[0112] In some embodiments of the present application, reference Figure 6 to Figure 8 The water pump assembly may include a water pump 5. The water pump 5 is used to discharge the condensed water in the water receiving tray 4 to the outside of the room.

[0113] The water pump 5 may include a water inlet 51 . The water inlet 51 is communicated with the water receiving tray 4 .

[0114] refer to Figure 6 In some embodiments of the present application, a water collecting tank 41 is provided in the water receiving tray 4. The water inlet 51 is located in the water collecting tank 41.

[0115] The water pump 5 may include a water outlet 52. The water outlet 52 may be communicated with a water delivery pipeline outside the ceiling machine 100.

[0116] Thus, the condensed water in the water receiving tray 4 can be transported to the outside of the ceiling machine 100 by the water pump 5, so that the condensed water in the water receiving tray 4 can be discharged in time to avoid overflow of the condensed water.

[0117] In some embodiments of the present application, the water pump 5 is disposed between the indoor heat exchanger 2 and the side wall of the box body 11. The water pump 5 and the indoor heat exchanger 2 are spaced apart.

[0118] In some embodiments of the present application, the water pump assembly may include a base 6. Figure 8 to Figure 11 The base 6 is disposed in the box body 11 , and a connecting hole 61 is formed on the base 6 .

[0119] A base 6 for installing a water supply pump 5 is arranged in the box 11, and the water pump 5 can be vertically installed in the box 11 through a bracket 7. The base 6 can be a mounting plate arranged in the box 11, or can be a part of the box 11, or can be a combination of the two.

[0120] In some embodiments of the present application, the water pump assembly may include a bracket 7. Fig. 9 , Fig.10 , Fig.12 The bracket 7 is used to install the water pump 5.

[0121] The water pump 5 is usually not directly mounted on the base 6 , but the water pump 5 is first mounted on the bracket 7 , and then the bracket 7 is connected to the base 6 .

[0122] In some embodiments of the present application, the water pump assembly may include a fastener 9. Fig.13 , the fastener 9 can be a bolt.

[0123] The bracket 7 and the base 6 are connected by fasteners 9 , so that the bracket 73 can be reliably fixed on the base 6 , thereby achieving effective installation of the water pump 5 .

[0124] It is understandable that when the water pump 5 is working, it will generate large vibrations, and will be transmitted to the base 6 through the bracket 7, thereby causing the box 11 to vibrate. The simultaneous vibration of the water pump 5 and the box 11 is likely to form resonance and generate large noise, which has a greater impact on the physical sensation of the ceiling machine.

[0125] In order to reduce or weaken the vibration transmission between the water pump 5 and the base 6, in this embodiment, reference Fig.13 A shock absorbing member 8 is provided between the bracket 73 and the base 6, and the shock absorbing member 8 absorbs part of the vibration energy, thereby weakening the transmission of the vibration and finally achieving a shock absorbing effect.

[0126] In some embodiments of the present application, reference Fig.13 , Fig.14 The interior of the shock absorbing member 8 is provided with a through hole 81. The through hole 81 is provided for the fastener 9 to pass through.

[0127] In some embodiments of the present application, reference Fig.14 An annular clamping portion 82 is provided on the outer peripheral surface of the shock absorbing member 8 .

[0128] In some embodiments of the present application, reference Fig.12 , Fig.13 The bracket 7 is provided with a mounting hole 71. When the shock absorbing member 8 is inserted into the mounting hole 71, the annular clamping portion 82 is adapted to be connected with the hole wall of the mounting hole 71.

[0129] The annular clamping portion 82 cooperates with the mounting hole 71 , so that the hole wall of the mounting hole 71 is adapted to be clamped in the annular clamping portion 82 , thereby embedding and fixing the shock absorbing component 8 on the bracket 7 .

[0130] refer to Figure 13 to Figure 16 A connecting hole 61 is provided on the base 6. When the bracket 7 is installed on the base 6, the through hole 81 is aligned with the connecting hole 61, and the fastener 9 passes through the through hole 81 of the shock absorber 8 and the connecting hole 61 in sequence, so that the bracket 7 and the base 6 are fixed to each other, thereby realizing the installation of the water pump 5.

[0131] It should be noted that, in this embodiment, a plurality of connecting holes 61 are provided, a plurality of mounting holes 71 are provided, and a plurality of shock absorbing members 8 and fasteners 9 are also provided correspondingly, thereby improving the installation firmness of the water pump.

[0132] In some embodiments of the present application, reference Fig.18 , Fig.19 The distance between the end surface of the fastener 9 facing the shock absorbing member 8 and the base 6 is L1, and the length of the shock absorbing member 8 in its axial direction is L2, L1>L2.

[0133] By setting L1 to be smaller than L2, the fastener 9 and the shock absorber 8 are clearance-fitted in the axial direction of the shock absorber 8, thereby preventing resonance of the housing 11 caused by interference fit, reducing the vibration transmitted from the water pump 5 to the housing 11, and thus reducing the noise of the whole machine.

[0134] In some embodiments of the present application, the annular clamping portion 82 is clearance-matched with the mounting hole 71. The fastener 9 is clearance-matched with the shock-absorbing member 8.

[0135] The fastener 9 and the shock absorber 8 are clearance-fitted, and the annular clamping portion 82 and the mounting hole 71 are clearance-fitted, which effectively prevents the fastener 9 and the shock absorber 8, and the shock absorber 8 and the bracket 7 from causing resonance of the box 11 after interference fit when the water pump 5 is installed, thereby reducing the vibration transmitted from the water pump 5 to the box 11, thereby reducing the noise of the whole machine.

[0136] In some embodiments of the present application, the shock absorbing member 8 is made of an elastic material such as chloroprene rubber or silicone rubber, so that the shock absorbing member 8 can absorb vibration energy by generating deformation.

[0137] In some embodiments of the present application, the shock absorbing member 8 is made of silicone or chloroprene rubber with a Shore hardness of 35 to 45 degrees.

[0138] The shock absorbing member 8 made of silicone or chloroprene rubber with a Shore hardness of 35 to 45 degrees has good elasticity and is conducive to absorbing vibration energy through its own deformation.

[0139] In some embodiments of the present application, reference Fig. 20 The through hole 81 includes a first through hole 811, a second through hole 812 and a third through hole 813 which are connected in sequence. The aperture D1 of the first through hole 811 is smaller than the aperture D2 of the second through hole 812, and the aperture D3 of the third through hole 813 is smaller than the aperture D2 of the second through hole 812.

[0140] The diameters of the first through hole 811 and the third through hole 813 are set to the diameter of the second through hole 812, so that when the shock absorber 8 is offset during assembly, only the inner walls of the first through hole 811 and the second through hole 812 are in contact with the fastener 9, thereby reducing the contact area between the fastener 9 and the shock absorber 8, avoiding resonance of the box 11 and reducing noise.

[0141] In some embodiments of the present application, the annular clamping portion 82 is disposed corresponding to the second through hole 812 .

[0142] The diameters of the first through hole 811 and the third through hole 813 are both smaller than the diameter of the second through hole 812. Thus, when the fastener 9 is installed in the through hole, an annular vibration-damping cavity can be formed between the outer circumferential surface of the fastener 9 and the inner wall of the second through hole 812, and the annular vibration-damping cavity can be used to reduce the radial load borne by the shock absorber 8.

[0143] In some embodiments of the present application, the annular clamping portion 82 is located between the first through hole 811 and the third through hole 813 along the axial direction of the through hole, and is opposite to the second through hole 812 .

[0144] When the vibration generated by the water pump 5 is transmitted to the bracket 7, the bracket 7 transmits the radial load to the shock absorber through the inner wall of the annular clamping portion 82. At this time, the shock absorber 8 generates bending deformation in the radial direction and squeezes the annular vibration-damping cavity, so that the volume of the annular vibration-damping cavity is reduced. The shock absorber 8 can generate bending deformation at a larger angle in the radial direction, thereby achieving a shock-absorbing effect and improving the radial shock-absorbing effect of the shock absorber 8.

[0145] In some other embodiments of the present application, in the axial direction of the shock absorbing member 8, the ratio of the length of the second through hole 812 to the length of the shock absorbing member 8 is 0.7-0.8.

[0146] The ratio of the length of the second through hole 812 to the length of the shock absorber 8 is 0.7 to 0.8, so that the length of the second through hole 812 is greater than the first through hole 811 and the third through hole 813. When the shock absorber 8 is offset during assembly, only the inner walls of the first through hole 811 and the third through hole 813 are in contact with the fastener 9, which effectively prevents the fastener 9 from contacting the shock absorber 8 over a large area to cause resonance of the box 11, effectively reducing the operating noise of the water pump 5 and improving the product competitiveness.

[0147] If the length of the second through hole 812 is too small compared to the length of the shock absorber 8, the fastener 9 will contact the shock absorber 8 over a large area, causing resonance of the box 11. If the length of the second through hole 812 is too small compared to the length of the shock absorber 8, the contact area between the fastener 9 and the shock absorber 8 will be too small, affecting the support of the shock absorber 8.

[0148] The ratio of the length of the second through hole 812 to the length of the shock absorbing member 8 is set within the above reasonable range, so as to avoid resonance problems while ensuring the supporting capacity of the shock absorbing member 8, thereby reducing the noise value of the whole machine.

[0149] In some other embodiments of the present application, the fastener 9 has a through portion that penetrates the through hole, and the diameter of the through portion is smaller than the apertures of the first through hole 811 and the third through hole 813 .

[0150] The diameter D4 of the through portion is smaller than the diameter D1 of the first through hole 811. The diameter D1 of the through portion is smaller than the diameter D3 of the third through hole 813, so that in the radial direction of the shock absorber 8, the fastener 9 and the shock absorber 8 have clearance fit, which facilitates the installation of the fastener 9.

[0151] In some other embodiments of the present application, the single-side gap between the through portion and the first through hole 811 and the third through hole 813 is c. 0<c, c≤0.5mm.

[0152] The unilateral clearance between the through portion and the first through hole 811 and the third through hole 813 cannot be too small, otherwise the clearance fit cannot be ensured. In order to ensure the clearance fit, the unilateral clearance should be a first parameter value greater than 0. For example, the first parameter value can be 0.1 mm, 0.15 mm, or 0.2 mm. Consider selecting a suitable and specific parameter in the specific design.

[0153] The unilateral gap between the through portion and the first through hole 811 and the third through hole 813 cannot be too large, otherwise the fixing reliability cannot be guaranteed. In order to ensure the fixing reliability, the unilateral gap should be smaller than the second parameter value. For example, the second parameter value can be 0.5 mm, 0.45 mm, or 0.4 mm. Consider selecting a suitable and specific parameter in the specific design.

[0154] When the fastener 9 is a bolt, the penetrating portion is the screw rod of the bolt.

[0155] In some other embodiments of the present application, the aperture of the first through hole 811 is the same as the aperture of the third through hole 813 .

[0156] The aperture of the first through hole 811 is set to be the same as the aperture of the third through hole 813, so as to facilitate the processing and forming of the shock absorbing member 8 and improve the production efficiency.

[0157] In some other embodiments of the present application, the annular clamping portion 82 includes an annular clamping groove, and in the radial direction of the fastener 9, the single-side clearance between the annular clamping groove and the mounting hole 71 is a. 0<a. a≤0.25mm.

[0158] The single-side clearance between the annular groove and the mounting hole 71 is set within the above-mentioned reasonable range to ensure that no shaking occurs, so that the shock absorber 8 and the bracket 7 are clearance-matched in the radial direction of the fastener 9 to avoid resonance with the box body 11 to generate large noise.

[0159] a cannot be too small, otherwise clearance fit cannot be guaranteed. In order to ensure clearance fit, the unilateral clearance a should be a third parameter value greater than 0. For example, the third parameter value can be 0.05mm, 0.1mm, or 0.15mm. Consider selecting a suitable and specific parameter during specific design.

[0160] a cannot be too large, otherwise it will cause shaking during transportation or installation. In order to ensure installation reliability, the single-side gap a should be smaller than the fourth parameter value. For example, the fourth parameter value can be 0.25mm, 0.23mm, or 0.2mm. Consider selecting a suitable and specific parameter during specific design.

[0161] In some other embodiments of the present application, in the axial direction of the fastener 9, the single-side clearance between the annular groove and the mounting hole 71 is b. 0<b. b≤0.15mm.

[0162] b cannot be too small, otherwise clearance fit cannot be guaranteed. In order to ensure clearance fit, the unilateral clearance b should be a fifth parameter value greater than 0. For example, the fifth parameter value can be 0.05mm, 0.08mm, or 0.1mm. Consider selecting a suitable and specific parameter in the specific design.

[0163] b cannot be too large. If it is too large, the vertical edge of the water pump assembly will be large, affecting the position of the drain port and the water tray, and thus affecting the drainage volume. In order to ensure the drainage volume, the single-side gap b should be smaller than the sixth parameter value. For example, the sixth parameter value can be 0.15mm, 0.13mm, or 0.11mm. Consider selecting a suitable and specific parameter in the specific design.

[0164] In some other embodiments of the present application, the difference between L1 and L2 is d. 0<d. d≤1mm.

[0165] d cannot be too small, otherwise the clearance fit between the fastener 9 and the shock absorber 8 cannot be guaranteed. In order to ensure the clearance fit, the difference d should be a seventh parameter value greater than 0. For example, the seventh parameter value can be 0.1 mm, 0.2 mm, or 0.3 mm. Consider selecting a suitable and specific parameter in the specific design.

[0166] d cannot be too large, otherwise the supporting force of the shock absorber 8 will be reduced. In order to ensure the supporting force of the shock absorber 8, the difference d should be smaller than the eighth parameter value. For example, the eighth parameter value can be 1mm, 0.95mm, or 0.9mm. Consider selecting a suitable and specific parameter in the specific design.

[0167] In some other embodiments of this application, refer to Fig.19 The shock absorbing member 8 comprises a first truncated cone section 83, a first supporting section 84, a second supporting section 85 and a second truncated cone section 86 which are sequentially arranged along the extending direction of the through hole 81. The first supporting section 84 and the second supporting section 85 are spaced apart to form an annular clamping portion 82.

[0168] It can be understood that, for the shock absorbing member 8, when the shock absorbing member 8 is subjected to pressure and torsional loads, the first supporting segment 84 and the second supporting segment 85 undergo elastic deformation, thereby achieving the effects of efficient shock absorption and buffer support.

[0169] In some other embodiments of the present application, the first support segment 84 and the second support segment 85 are symmetrically arranged along the first axis. The through hole is an axisymmetric structure symmetrical along the first axis.

[0170] Specifically, the annular clamping portion 82 is located in the middle of the shock absorber 8, the first supporting segment 84 and the second supporting segment 85 are symmetrically arranged, and the through hole 81 is symmetrical along the first axis, ensuring that the shock absorber 8 is symmetrical up and down, which has an anti-mistake effect and makes it unnecessary to distinguish the installation direction of the shock absorber 8 during installation, thereby improving production efficiency.

[0171] The ceiling machine 100 provided by the utility model optimizes the material hardness of the shock absorbing member 8, optimizes the matching clearance between the shock absorbing member 8 and the fastener 9, and the matching clearance between the bracket 7 and the shock absorbing member 8, and sets each matching clearance within a reasonable range, thereby reducing the vibration transmitted from the water pump 5 to the box body 11, thereby reducing noise.

[0172] Taking the existing batch water pump products as an example, the noise test was compared by assembling the ordinary shock absorber 8 and the optimized shock absorber in the utility model. The water pump equipped with the shock absorber in this embodiment has significantly reduced operating noise. The noise test data of the water pump equipped with the ordinary shock absorber is shown in Table 1 below, and the noise test data of the water pump equipped with the shock absorber in this embodiment is shown in Table 2 below.
