Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning devices, and more specifically, to a water pumping motor assembly and an air conditioning device having the same. Background Art

[0002] At present, during the operation of an air conditioning device, the magnitude of noise is an important parameter for measuring the performance of the air conditioner. Excessive noise will affect the user experience. Specifically, a portable air conditioner uses a water pumping motor to send the condensed water on the evaporator to the condenser to increase heat exchange and improve the heat exchange efficiency of the two heat exchangers.

[0003] However, during the operation of the water pumping motor, the imbalance of the rotor rotation of the water pumping motor will cause the motor to vibrate. Since the water pumping motor is an integrated structure, this vibration will be transmitted to the outer shell of the water pumping motor. At the same time, the protrusions on both sides of the outer shell of the water pumping motor are fixed to the base of the chassis with screws, so that there is a rigid contact between the outer shell of the water pumping motor and the base, resulting in the expansion of the vibration and generating a large amount of noise. Summary of the Utility Model

[0004] The main purpose of the present utility model is to provide a water pumping motor assembly and an air conditioning device having the same, so as to solve the problem that the water pumping motor in the prior art has large vibration and large noise during operation, which affects the user experience.

[0005] To achieve the above object, according to one aspect of the present utility model, there is provided a water pumping motor assembly, including: a water pumping motor, including an outer shell and a motor body located inside the outer shell, and a connecting convex portion is provided on the outer shell; a seat body assembly for supporting the water pumping motor and including a base and a fixing structure, the fixing structure has a groove, and the groove and the base surround to form an installation cavity for installing the connecting convex portion; an elastic structure located between the cavity wall of the installation cavity and the connecting convex portion; wherein, when the elastic structure and the connecting convex portion are in an assembled state, the volume of the elastic structure is greater than the volume of the installation cavity.

[0006] Further, the elastic structure has a countersunk hole, and at least a part of the connecting convex portion extends into the countersunk hole.

[0007] Further, the elastic structure is a block structure, and the thickness of the block structure is greater than the height of the installation cavity.

[0008] Further, a matching component is provided between the base and the fixing structure, and the matching component includes: a first matching portion provided on the base; a second matching portion provided on the fixing structure and spaced from the groove; wherein, one of the first matching portion and the second matching portion is a protrusion, and the other of the first matching portion and the second matching portion is a recess, and the protrusion extends into the recess and is in limit matching with the recess.

[0009] Further, there is one mating component; alternatively, there are multiple mating components, and the multiple mating components are arranged at intervals in the circumferential direction around the groove.

[0010] Further, the extending direction of the recess is the same as that of the groove, and the depth of the recess is less than the depth of the groove.

[0011] Further, the recess and / or the groove is a rectangular groove, and the extending direction of the rectangular groove is the same as the height direction of the water pumping motor assembly.

[0012] Further, the elastic structure is made of rubber or silica gel.

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present invention in detail with reference to the drawings and in conjunction with the embodiments.

[0027] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0028] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present invention.

[0029] In order to solve the problem that the water pumping motor in the prior art has large vibration and large noise during operation, which affects the user experience, the present application provides a water pumping motor assembly and an air conditioner device having the same.

[0030] Such as Figures 1 to 4As shown in the figure, the water pumping motor assembly includes a water pumping motor 10, a seat body assembly 20, and an elastic structure 30. The water pumping motor 10 includes a housing and a motor body located inside the housing, and a connecting convex portion 11 is provided on the housing. The seat body assembly 20 is used to support the water pumping motor 10 and includes a base 21 and a fixing structure 22. The fixing structure 22 has a groove 221, and the groove 221 and the base 21 surround to form an installation cavity for installing the connecting convex portion 11. The elastic structure 30 is located between the cavity wall of the installation cavity and the connecting convex portion 11. Among them, when the elastic structure 30 and the connecting convex portion 11 are in an assembled state, the volume of the elastic structure 30 is larger than the volume of the installation cavity.

[0031] Applying the technical solution of this embodiment, since the elastic structure 30 is located between the cavity wall of the installation cavity and the connecting convex portion 11, an elastic connection between the connecting convex portion 11 and the seat body assembly 20 is realized, avoiding the vibration and noise generated on the connecting convex portion 11 from being transmitted to the seat body assembly 20. When the elastic structure 30 and the connecting convex portion 11 are in an assembled state, the volume of the elastic structure 30 is larger than the volume of the installation cavity, so that the installation cavity can fully compress and fix the elastic structure 30 and the connecting convex portion 11, thereby improving the support stability of the seat body assembly 20 for the water pumping motor and solving the problem that the water pumping motor has large vibration and large noise during operation in the prior art, which affects the user experience.

[0032] In this embodiment, after the connecting convex portion 11 (elastic structure 30) is pressed on the base 21, the fixing structure 22 is pressed on the connecting convex portion 11 (elastic structure 30) to realize the assembly between the water pumping motor and the seat body assembly 20.

[0033] In this embodiment, the elastic structure 30 has a countersunk hole, and at least part of the connecting convex portion 11 extends into the countersunk hole. In this way, on the one hand, the contact area between the elastic structure 30 and the connecting convex portion 11 is increased, improving the connection stability between the two; on the other hand, the elastic structure 30 fully wraps the connecting convex portion 11 to ensure that the elastic structure 30 is located between the cavity wall of the installation cavity and the connecting convex portion 11, and the connecting convex portion 11 does not directly contact the cavity wall of the installation cavity. At the same time, the above setting makes the structure of the elastic structure 30 simpler, easier to process and realize, reducing the processing cost and processing difficulty of the elastic structure 30.

[0034] In this embodiment, the elastic structure 30 is arranged on the connecting convex portion 11 to make the disassembly and assembly of the elastic structure 30, the connecting convex portion 11, and the seat body assembly 20 easier and simpler, reducing the disassembly and assembly difficulty of the three.

[0035] In other embodiments not shown in the drawings, the elastic structure is arranged on the cavity wall of the installation cavity. In this way, the above setting makes the installation position of the elastic structure more flexible to meet different use requirements and working conditions, and also improves the processing flexibility of the staff.

[0036] In this embodiment, the elastic structure 30 is a block structure, and the thickness of the block structure is greater than the height of the installation cavity. In this way, when the fixing structure 22 presses the elastic structure 30, the above setting of the thickness of the block structure ensures that the fixing structure 22 can completely press the block structure, avoiding loosening between the elastic structure 30 and the water pumping motor 10. At the same time, the above setting makes the structure of the elastic structure 30 simpler, easier to process and implement, reducing the processing cost and difficulty of the elastic structure 30.

[0037] In other embodiments not shown in the drawings, the elastic structure is a sleeve.

[0038] As Figure 1 shown, a matching component is provided between the base 21 and the fixing structure 22. The matching component includes a first matching portion 41 and a second matching portion 42. The first matching portion 41 is provided on the base 21, and the second matching portion 42 is provided on the fixing structure 22 and is spaced apart from the groove 221. Wherein, one of the first matching portion 41 and the second matching portion 42 is a protrusion, and the other of the first matching portion 41 and the second matching portion 42 is a recess, and the protrusion extends into the recess and is in limit fit with the recess. In this way, the above setting of the matching component increases the contact area between the base 21 and the fixing structure 22, thereby improving the assembly stability of the two. At the same time, the above setting makes the selection of the structures of the first matching portion 41 and the second matching portion 42 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0039] In this embodiment, the first matching portion 41 is a convex portion and the second matching portion 42 is a concave portion. The protrusion extends into the recess and is in limit fit with the recess to realize the assembly of the base 21 and the fixing structure 22.

[0040] In other embodiments not shown in the drawings, the first matching portion is a concave portion and the second matching portion is a convex portion. The protrusion extends into the recess and is in limit fit with the recess to realize the assembly of the base and the fixing structure.

[0041] Optionally, there is one matching component; or, there are multiple matching components, and the multiple matching components are arranged at intervals in the circumferential direction around the groove 221. In this way, the above setting makes the selection of the number of the matching components more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff. At the same time, when there are multiple matching components, the multiple matching components further increase the matching area between the base 21 and the fixing structure 22, improve the matching stability of the two, and also improve the support stability of the seat body assembly 20 for the water pumping motor 10.

[0042] In this embodiment, there are three matching components, and the three matching components are arranged at intervals in the circumferential direction around the groove 221.

[0043] It should be noted that the number of mating components selected is not limited to this, and can be adjusted according to the working conditions and usage requirements. Optionally, the number of mating components is two, or four, or five, or more.

[0044] In this embodiment, the extending direction of the concave portion is the same as that of the groove 221, and the depth of the concave portion is less than that of the groove 221. In this way, on the one hand, the above setting avoids interference between the concave portion and the groove 221 and increases the processing difficulty of the fixing structure 22; on the other hand, it improves the structural strength of the fixing structure 22 and extends the service life of the fixing structure 22.

[0045] Optionally, the concave portion and / or the groove 221 is a rectangular groove, and the extending direction of the rectangular groove is the same as the height direction of the water pumping motor assembly. In this way, the above setting makes the structure of the concave portion and / or more simple, easy to process and implement, and reduces the processing cost and difficulty of the seat body assembly 20.

[0046] Optionally, the elastic structure 30 is made of rubber or silica gel. In this way, the above setting makes the material selection of the elastic structure 30 more flexible to meet different usage requirements and working conditions, and also improves the processing flexibility of the staff.

[0047] In this embodiment, the elastic structure 30 is a rubber block.

[0048] In this embodiment, the height of the seat body assembly 20 is greater than the outer diameter of the housing. In this way, after the water pumping motor assembly is assembled, the above setting makes the water pumping motor 10 suspended, avoiding the contact between the housing of the water pumping motor 10 and the chassis, thereby avoiding abnormal noise.

[0049] In this embodiment, by adjusting the running time of the water pumping motor, the condensate water volume can be maintained at a relatively low level, thereby reducing the water pumping sound to a level that can be covered by the running noise of the air conditioning device, thus avoiding the water pumping sound from affecting the user's sleep.

[0050] Specifically, in order to avoid the water pumping sound from being too loud and affecting the user's sleep, the running time of the water pumping motor is controlled. This program is named "sleep mode", and its control method is as follows:

[0051] When the user is about to go to sleep, the sleep mode is turned on and the wind speed gears X1 - X3 are set. Then the compressor is turned on and the air conditioner starts to blow cold air. After the compressor has been running for 120 s, the water injection motor assembly starts to operate. The reason is that the water injection motor and the compressor are on the same side of the air conditioner. If both are turned on simultaneously, it will cause a very loud startup noise. To avoid this situation, the water injection motor is delayed by 120 s to turn on, so as to reduce the overall noise of the unit during startup. After the water injection motor starts running, it runs continuously for 30 min first. This is because initially the interior of the air conditioner is dry and there is no water, so there will be no water injection sound temporarily. At the same time, after turning on the water injection motor, it can disturb the internal air of the condenser, thereby increasing the heat exchange efficiency and improving the cooling capacity. In addition, according to the experimental measurements, regardless of the air humidity, almost no condensed water is generated within the first 30 min of the water injection motor's operation, so there will be no water injection sound, which will not affect the user's sleep. After that, the humidity of the air at the evaporator inlet is detected, with a frequency of once every 2 s (the detection frequency does not need to be too high, as long as the humidity can be detected in a timely manner. Since the running time of the water injection motor is mainly calculated in minutes, the detection frequency is less than a minute). If the humidity at the inlet is ≥75%, the water injection motor stops for 10 min first and then runs for 15 min, and so on in a cycle (when the air humidity is too high, condensed water starts to be generated at the condensation end after 30 min. At this time, the water injection motor stops for 10 min mainly to continue the "zero noise" of the water injection motor, which is convenient for the user to sleep. At the same time, only a small amount of water will be generated during this period. When the water injection motor runs again, according to the experimental measurements, the water injection sound can be reduced a lot within 30 s and will be covered by the air conditioner noise, and there will be no obvious "crackling" water injection sound).

[0052] If the air humidity at the inlet is less than 75%, it is then judged whether the compressor frequency is ≥50 Hz. If the above conditions are met, the water injection motor stops for 10 min and then runs for 15 min. The main reason is that when the compressor frequency is high, the heat exchange amount increases, and condensed water is likely to be generated in the condenser. When the compressor frequency is less than 50 Hz, since the humidity is low and the compressor frequency is low at this time, the speed of condensed water generation in the condenser is slow. According to the experimental measurements, the condensed water generated within 20 min after the water injection motor stops can be drained within 30 s, and then the water injection motor runs for 10 min mainly to better maintain a low condensed water volume so that there will be no obvious "crackling" sound during the next water injection.
