Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a motor and an air conditioner. Background Technology

[0002] Currently, integrated kitchen air conditioners are installed in the kitchen ceiling without pre-installed drain pipes. The condensate produced during operation needs to be consumed, so it needs to be pumped to the condenser on the outdoor unit side to evaporate using high temperatures. To improve the efficiency of condensate consumption, the following two steps are required: first, a water pump collects the condensate produced indoors; second, a pump motor pumps the collected condensate to the outdoor condenser for evaporation. This process requires two motors; the absence of even one motor will affect system efficiency. However, installing two motors on the machine is costly, structurally complex, and detrimental to miniaturization design. Utility Model Content

[0053] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0055] Currently, integrated kitchen air conditioners are installed in the kitchen ceiling without pre-installed drain pipes. The condensate produced during operation needs to be consumed, so it needs to be pumped to the condenser on the outdoor unit side to evaporate using high temperatures. To improve the efficiency of condensate consumption, the following two steps are required: First, a water pump collects the condensate produced indoors; second, a pump motor pumps the collected condensate to the outdoor condenser for evaporation. This process requires two motors; the absence of even one motor will affect system efficiency. However, installing two motors on the machine is costly, structurally complex, and detrimental to miniaturization design.

[0056] To address this issue, this invention proposes a motor 100 that solves the problem of limited water pumping height in the motor 100, while simultaneously improving the evaporation efficiency of the air conditioner.

[0057] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The motor 100 includes:

[0058] Pump body 1;

[0059] Motor body 2, which is drivenly connected to pump body 1;

[0060] The water pumping assembly 3 is driven and connected to the motor body 2. When the motor body 2 rotates, it drives the pump body 1 and the water pumping assembly 3 to rotate synchronously.

[0061] As is understandable, an electric motor 100 is a device that converts electrical energy into mechanical energy and is widely used in various devices and systems that require drive or motion functions. Almost all applications involving rotation, linear movement, or other forms of mechanical motion may use an electric motor 100. The following are some common types of household appliances that use electric motors 100: air conditioners, refrigerators, washing machines, etc.

[0062] The motor 100 of this invention is mainly used in air conditioners that require condensate treatment, especially air conditioners installed in kitchen ceilings. The air conditioner may include an indoor unit 200 and an outdoor unit 300, wherein the indoor unit 200 may include an evaporator 210, and the outdoor unit 300 may include a condenser 330 and a compressor 340. The compressor 340 is used to draw in low-temperature, low-pressure gaseous refrigerant from the evaporator 210 and transform it into a high-temperature, high-pressure gas through a compression process; the condenser 330 is used to receive the high-temperature, high-pressure gaseous refrigerant from the compressor 340 and release heat to the external environment through heat dissipation (usually with the help of a fan or coolant). During this process, the refrigerant gradually cools and condenses into a relatively low-temperature, high-pressure liquid. After condensation, the refrigerant is in a state suitable for entering the next stage, i.e., a preparatory state before expansion. When the low-temperature, low-pressure liquid refrigerant, after being depressurized by the expansion valve, flows into the evaporator 210, it absorbs heat from the surrounding air. This process causes the refrigerant temperature to rise and change from a liquid to a gas, while effectively cooling the air flowing through the evaporator 210, thereby lowering the indoor temperature.

[0063] It is easy to see that the evaporator 210 is mainly responsible for absorbing heat from the indoor air to achieve a cooling effect, while the condenser 330 is responsible for dissipating this heat, as well as the additional heat generated during the operation of the air conditioner, to the outside, maintaining the continuous operation of the cooling cycle. Working together, they ensure that the air conditioner can effectively regulate indoor temperature and humidity. To improve this problem, the motor 100 proposed in this invention not only acts as a pump 1 to extract the condensate generated during the operation of the evaporator 210 and pump it to the condenser 330, but also, through an additional water-pumping component 3, pumps any condensate that has not yet evaporated back to the condenser 330 to ensure it is fully evaporated. However, it is worth noting that during the operation of the air conditioner, the moisture in the air passing through the evaporator 210 will condense into water droplets (i.e., condensate), and this moisture needs to be effectively removed to avoid water accumulation. To improve this problem, the motor 100 proposed in this utility model can not only act as a pump body 1 to extract the condensate generated during the operation of the evaporator 210 and pump it to the condenser 330, but also use an additional water pumping component 3 to pump the condensate that has not yet evaporated back to the condenser 330 to ensure that it is fully evaporated.

[0064] In this embodiment, the motor 100 may include a pump body 1 and a motor body 2. The pump body 1 can be connected to the condensate collection area of ​​the indoor unit 200. When it is working, it can pump the condensate generated during the operation of the evaporator 210 to the condenser 330 to cool the condenser 330, thereby improving the overall energy efficiency of the air conditioner. The motor body 2 serves as the power source for the entire motor 100. The motor body 2 is driven by the pump body 1. When the motor body 2 rotates, it can drive the pump body 1 to operate, thereby achieving effective pumping of condensate. Considering the challenges in actual operation, namely that in some cases, the pump body 1 may deliver a large amount of condensate to the condenser 330 in a short period of time, and the condenser 330 may not be able to handle all the water volume in time. This may cause some of the condensate that fails to evaporate in time to flow downwards due to gravity and accumulate in the second housing 310 of the outdoor unit 300. To address this situation, the motor 100 also includes a water-pumping assembly 3. The second housing 310 of the outdoor unit 300 may be equipped with a water storage tank 303, which can be used to store unevaporated condensate from the condenser 330. The water-pumping assembly 3 can be positioned corresponding to the water storage tank 303. The water-pumping assembly 3 is also driven by the motor body 2. While the motor body 2 rotates, it not only supports the operation of the pump body 1 but also actively handles the unevaporated condensate. It pumps excess condensate from the water storage tank 303 back onto the surface of the condenser 330, assisting in accelerating the evaporation process and preventing unnecessary accumulation of condensate, thereby maintaining the efficient operation of the motor 100. In other words, during the operation of the air conditioner, condensate is collected and pumped away by the pump body 1, then transported to the condenser 330 under the drive of the motor body 2. Simultaneously, the motor body 2 also drives the water-pumping assembly 3 to ensure that any condensate that has not yet evaporated can be pumped back to the condenser 330, further assisting the evaporation process.

[0065] The key advantage of this invention lies in its ability to allow a single motor 100 to perform two important tasks: first, to extract condensate from inside the air conditioner; and second, to redistribute this condensate onto the condenser 330 to enhance evaporation. This integrated approach not only reduces the number of motors 100 required, lowering manufacturing and maintenance costs, but also helps optimize the condensate handling process, improve evaporation efficiency, and reduce unnecessary energy consumption. Furthermore, this design helps maintain the compactness and efficiency of the air conditioner.

[0066] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The motor 100 also includes a magnetic coupling component 4, and the motor body 2 and the pump body 1 are coupled together through the magnetic coupling component 4.

[0067] In this embodiment, by providing the magnetic coupling component 4, non-contact power transmission between the motor body 2 and the pump body 1 can be allowed. For example, the magnetic coupling component 4 can consist of a first magnetic coupling element 41 mounted on the motor body 2 and a second magnetic coupling element 42 mounted on the pump body 1. There is no direct mechanical connection between the first magnetic coupling element 41 and the second magnetic coupling element 42; instead, torque is transmitted through the interaction of magnetic fields. When the motor body 2 starts and begins to rotate, the first magnetic coupling element 41 mounted on it also rotates. Since both the first magnetic coupling element 41 and the second magnetic coupling element 42 are made of strongly magnetic materials, a strong magnetic field is generated between them. As the first magnetic coupling element 41 rotates, its magnetic field passes through the pump casing 11 of the pump body 1 and interacts with the magnetic field of the second magnetic coupling element 42. At this time, the rotating magnetic field of the first magnetic coupling element 41 applies a rotational torque to the second magnetic coupling element 42 located on the pump body 1. This torque is sufficient to overcome the resistance inside the pump body 1, causing the second magnetic coupling element 42 to rotate along with the first magnetic coupling element 41, thereby driving the entire pump body 1 to rotate. The pump impeller 12 or other fluid transport components inside the pump body 1 rotate accordingly, thereby effectively pumping condensate. Because the power transmission is through a magnetic field, even a small amount of misalignment or vibration between the pump body 1 and the motor body 2 will not significantly affect the power transmission effect. Since there is no direct mechanical contact between the motor body 2 and the pump body 1, friction between them can be reduced, wear rate can be lowered, and the service life of the motor 100 can be extended. Furthermore, when the pump body 1 is installed in the indoor unit 200, the indoor unit 200 does not need to drill holes in the pump body 1 to achieve a drive connection with the motor body 2, which can improve the airtightness of the indoor unit 200, prevent condensate leakage or external media from entering the interior of the indoor unit 200, and enhance the reliability of the air conditioner.

[0068] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The magnetic coupling assembly 4 includes a first magnetic coupling element 41 and a second magnetic coupling element 42, wherein the first magnetic coupling element 41 and the second magnetic coupling element 42 are coupled together.

[0069] The motor body 2 is driven to be connected to the first magnetic coupling member 41, and the second magnetic coupling member 42 is driven to be connected to the pump body 1. When the motor body 2 drives the first magnetic coupling member 41 to rotate, it can drive the second magnetic coupling member 42 to rotate, thereby driving the pump body 1 to rotate.

[0070] In this embodiment, the first magnetic coupling element 41 is mounted on the motor body 2 and directly driven connected to the motor shaft 21 of the motor body 2. This means that when the motor body 2 starts and rotates, the first magnetic coupling element 41 also rotates synchronously. The first magnetic coupling element 41 can be implemented using a built-in ring magnet made of a strongly magnetic material, capable of generating a strong rotating magnetic field during rotation. The second magnetic coupling element 42 can be installed inside the pump casing 11 of the pump body 1, not directly connected to the motor body 2. It is separated from the first magnetic coupling element 41 by the pump casing 11, ensuring that condensate water does not enter the motor body 2. The second magnetic coupling element 42 can also be implemented using a built-in ring magnet, enabling it to respond to changes in the magnetic field from the first magnetic coupling element 41. There is no direct mechanical contact between the first magnetic coupling element 41 and the second magnetic coupling element 42; instead, torque is transmitted through magnetic field interaction. The rotating magnetic field generated by the first magnetic coupling element 41 passes through the pump casing 11 and interacts with the magnetic field of the second magnetic coupling element 42. When the first magnetic coupling element 41 rotates, its rotating magnetic field applies a rotational torque to the second magnetic coupling element 42. This torque is sufficient to overcome the resistance within the pump body 1, causing the second magnetic coupling element 42 to rotate along with the first magnetic coupling element 41. Since the second magnetic coupling element 42 is driven to connect to the pump body 1, the rotation of the second magnetic coupling element 42 will drive the entire pump body 1 to rotate, thereby achieving effective pumping of condensate.

[0071] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The position of the first magnetic coupling element 41 is set to correspond to the position of the second magnetic coupling element 42.

[0072] In this embodiment, the positions of the first magnetic coupling element 41 and the second magnetic coupling element 42 are precisely aligned, ensuring that the magnetic field is effectively transmitted from the first magnetic coupling element 41 to the second magnetic coupling element 42, stabilizing the torque applied to the second magnetic coupling element 42, and thus improving the rotational stability of the pump body 1. Furthermore, the corresponding arrangement of the two magnetic coupling elements helps maintain a minimum and consistent air gap distance, which is crucial for maintaining a stable magnetic field strength and efficient energy transfer. A smaller air gap not only improves efficiency but also reduces energy loss caused by an excessively large air gap. In addition, the precise correspondence between the first magnetic coupling element 41 and the second magnetic coupling element 42 allows the magnetic coupling assembly 4 to provide optimal performance under various operating conditions, including rapid response during startup, smooth rotation during operation, and immediate stoppage upon shutdown.

[0073] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The pump body 1 includes:

[0074] Pump housing 11, the second magnetic coupling member 42 is disposed inside the pump housing 11;

[0075] The water pump impeller 12 is disposed on the pump casing 11;

[0076] The second magnetic coupling element 42 is driven to connect with the water pump impeller 12. When the second magnetic coupling element 42 rotates, it drives the water pump impeller 12 to rotate.

[0077] In this embodiment, the pump casing 11 is the outer shell of the pump body 1, forming a pump cavity 101 inside, and is provided with an inlet 102 and an outlet 103. The pump cavity 101 is used to contain condensate and provides working space for the pump impeller 12 and the second magnetic coupling member 42. The inlet 102 can be connected to the condensate collection area of ​​the indoor unit 200, allowing condensate to enter the pump cavity 101. The outlet 103 communicates with the condenser 330, delivering the pumped condensate to the condenser 330 to assist in cooling the condenser 330 and improve the energy efficiency of the air conditioner. The pump impeller 12 is a key component directly responsible for drawing and pumping condensate. It is usually made of corrosion-resistant material to adapt to working conditions in contact with water. The shape and number of pump impellers 12 are not limited and can be set according to the pump performance. There is a direct or indirect drive connection between the second magnetic coupling member 42 and the pump impeller 12. This connection can be mechanical (e.g., shaft connection) or achieved through other forms of energy conversion mechanisms. When the motor body 2 drives the first magnetic coupling element 41 to rotate, the generated rotating magnetic field passes through the air gap and acts on the second magnetic coupling element 42, causing the latter to also begin to rotate. As the second magnetic coupling element 42 rotates, it drives the water pump impeller 12 to rotate as well. The rotation of the water pump impeller 12 generates centrifugal force inside the pump casing 11, thereby pushing the sucked-in condensate from the inlet 102 to the outlet 103, completing the pumping action. The power transmission achieved through magnetic coupling technology ensures that the water pump impeller 12 receives a stable torque input, thus providing continuous and efficient condensate discharge.

[0078] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The motor body 2 includes:

[0079] The motor shaft 21, the first magnetic coupling element 41 and the water-spraying assembly 3 are sleeved on the motor shaft 21; when the motor shaft 21 rotates, it drives the first magnetic coupling element 41 and the water-spraying assembly 3 to rotate synchronously.

[0080] In this embodiment, the motor body 2 may include a motor housing 23 and a motor shaft 21. The motor shaft 21, mounted on the motor housing 23, is one of the core components of the motor body 2. It is responsible for transmitting the rotational motion generated by the motor 100. The motor shaft 21 must possess sufficient strength and rigidity to withstand the torque during operation and ensure stable operation over a long period. A first magnetic coupling element 41 is sleeved on the motor shaft 21 and is typically fixed by a key connection or interference fit to ensure synchronous rotation with the motor shaft 21. It consists of a built-in ring magnet and is used to generate a rotating magnetic field that interacts with the second magnetic coupling element 42 (located inside the pump body 1). The water pumping assembly 3 is also sleeved on the motor shaft 21, located on one side or the other end of the motor body 2. Its function is to mechanically pump condensate onto the condenser 330 for evaporation when the motor shaft 21 rotates. When the motor shaft 21 rotates, since the first magnetic coupling element 41 and the water pumping component 3 are directly mounted on the motor shaft 21, they will rotate synchronously with the motor shaft 21. This synchronous rotation design can ensure the time coordination between the pump body 1 and the water pumping component 3 and improve the overall efficiency of the motor 100.

[0081] The motor body 2 may also include a rotor assembly 22 and a stator assembly. The rotor assembly 22 and stator assembly are the main driving components of the motor body 2. The stator assembly is fixed to the motor housing 23, and the rotor assembly 22 is similarly mounted on the motor shaft 21. The rotor assembly 22 can be located outside or inside the stator assembly, depending on the type of motor 100. If the motor 100 is an external rotor motor 100, the rotor assembly 22 is located outside the stator assembly; otherwise, it is located inside the stator assembly. When the stator assembly is energized, electromagnetic induction causes the rotor assembly 22 to rotate, thereby driving the motor shaft 21 and its first magnetic coupling member 41 and water pumping assembly 3 to rotate together. The first magnetic coupling member 41 and the second magnetic coupling member 42 on the pump body 1 transmit power non-contactly through magnetic field interaction. The rotating magnetic field of the first magnetic coupling member 41 applies a rotational torque to the second magnetic coupling member 42, causing the second magnetic coupling member 42 to rotate along with the first magnetic coupling member 41, thereby driving the entire pump body 1 to rotate and effectively pump condensate water. While the motor shaft 21 rotates, it not only drives the pump body 1 to operate, but also drives the water pumping assembly 3 to pump the condensate stored in the water storage tank 303 onto the condenser 330 to assist the evaporation process of the condensate and improve the energy efficiency of the air conditioner.

[0082] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The motor shaft 21 has a first end 211 and a second end 212 that are arranged opposite to each other. The first magnetic coupling member 41 is sleeved on the first end 211, and the water pumping component 3 is sleeved on the second end 212.

[0083] In this embodiment, the first end 211 is located on one side of the rotor assembly 22 and is responsible for driving the first magnetic coupling member 41. The second end 212 is located on the other side of the rotor assembly 22 and is responsible for driving the water pumping assembly 3. By installing components with different functions at opposite ends of the motor shaft 21, when the motor shaft 21 rotates, the first magnetic coupling member 41 at the first end 211 drives the water pump impeller 12 inside the pump body 1 to rotate through the magnetic field, completing the extraction and pumping of condensate; at the same time, the water pumping assembly 3 at the second end 212 also rotates under the drive of the motor shaft 21, pumping the collected condensate onto the condenser 330 for evaporation. That is, by placing components with different functions at both ends of the motor shaft 21, complex mechanical connections can be reduced, making the entire motor 100 more concise and compact. Since the first magnetic coupling member 41 and the water pumping assembly 3 are relatively independent, disassembly and replacement become simpler and faster, reducing the maintenance cost and difficulty of the motor 100.

[0084] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The water-spraying assembly 3 includes a first water-spraying impeller 31 and a second water-spraying impeller 32;

[0085] The first water-spraying impeller 31 and the second water-spraying impeller 32 are spaced apart and sleeved on the motor shaft 21;

[0086] In this embodiment, by setting two water-spraying impellers, the evaporation efficiency of condensate can be improved at the same time. The two water-spraying impellers are set at intervals, that is, a certain distance is maintained between the two water-spraying impellers, which can avoid mutual interference, allow each water-spraying impeller to operate independently, and optimize the flow path of condensate to ensure uniform spraying.

[0087] In another embodiment of this utility model, referring to Figure 1 and Figure 2 The diameter of the first water-spraying impeller 31 is larger than the diameter of the second water-spraying impeller 32.

[0088] In this embodiment, by limiting the diameters of the two impellers to different sizes, multi-layered condensate spraying can be achieved simultaneously. The larger-diameter first impeller 31 is responsible for long-distance, large-area spraying, while the smaller-diameter second impeller 32 supplements with close-range, fine spraying, thus covering a wider evaporation area. The synergistic effect between the two impellers improves the dispersion of condensate, increases the chance of contact with the condenser 330 surface, and thereby improves evaporation efficiency.

[0089] This utility model also proposes an air conditioner, as shown in the reference. Figure 1 and Figure 2The air conditioner includes a motor 100, the specific structure of which is as described in the above embodiments. Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0090] It is understood that the air conditioner can be at least one of the following: kitchen air conditioner, residential or commercial central air conditioner, wall-mounted air conditioner, and window air conditioner. In this embodiment, the air conditioner is specifically a kitchen air conditioner. This air conditioner integrates the aforementioned motor 100, which can use the pump body 1 in the motor 100 to draw condensate generated on the indoor side to the outdoor side for evaporation. It can also use the water-pumping component 3 in the motor 100 to pump condensate that cannot evaporate on the outdoor side to the outdoor side for secondary evaporation. This not only solves the problem of limited water pumping height in existing air conditioners' motors 100, but also improves the air conditioner's evaporation efficiency and energy efficiency. Furthermore, by integrating the functions of the pump body 1 and the water-pumping component 3 into a single motor 100, the number of required components can be reduced, making the overall structure of the air conditioner more compact and facilitating miniaturization design, making it particularly suitable for applications with limited space (kitchen ceiling).

[0091] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The air conditioner includes:

[0092] The outdoor unit 300, wherein the water pumping assembly 3 of the motor 100 is disposed in the outdoor unit 300; the water pumping assembly 3 is used to pump the unevaporated condensate from the outdoor unit 300 to the outdoor unit 300.

[0093] The indoor unit 200 has a pump body 1 of the motor 100 installed in it; the pump body 1 is used to pump the condensate generated by the operation of the indoor unit 200 to the outdoor unit 300 during operation.

[0094] In this embodiment, the condensate generated during the operation of the indoor unit 200 is first collected by the pump body 1 and transferred to the outdoor unit 300 through pipes or conduits. This process not only cools the outdoor unit 300 and improves the energy efficiency of the air conditioner, but also prevents condensate from accumulating indoors, maintaining good cooling performance and ambient humidity control. Simultaneously, if some condensate in the outdoor unit 300 fails to evaporate in time, the water-spraying assembly 3 will spray it evenly back onto the outdoor unit 300 to promote evaporation. Through this process, the condensate in the indoor unit 200 is effectively treated, reducing the indoor unit 200's reliance on external drainage facilities and mitigating potential problems caused by water accumulation in the indoor unit 200 (such as leaks and mold growth).

[0095] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The indoor unit 200 includes:

[0096] Evaporator 210;

[0097] The first housing 220 is provided, and the evaporator 210 and the pump body 1 are disposed inside the first housing 220. The first housing 220 is provided with a water collection tank 201, which is positioned corresponding to the evaporator 210. The water collection tank 201 is used to collect the condensate generated during the operation of the evaporator 210. The water collection tank 201 is connected to the water inlet 102 of the pump body 1.

[0098] In this embodiment, the evaporator 210 is a key component responsible for cooling in the air conditioning system. It absorbs heat through the phase change of the refrigerant, lowers the indoor air temperature, and produces condensate. The first housing 220 is the main outer shell of the indoor unit 200, used to house components such as the evaporator 210 and the pump body 1. It not only protects the internal mechanical and electrical components from external environmental influences but also provides necessary sealing and stability. A water collection tank 201 is provided inside the first housing 220, located corresponding to the evaporator 210, specifically for collecting the condensate generated during the operation of the evaporator 210. The water collection tank 201 can be a groove directly formed in the first housing 220 or a groove formed in a mounting block protruding from the first housing 220; its formation method is not limited here and can be set according to the condensate collection requirements. The water collection tank 201 can be directly connected to the water inlet 102 of the pump body 1 through pipes or other means, ensuring that the condensate can smoothly enter the pump body 1 for subsequent processing. By designing a water collection tank 201 to collect condensate and connecting it directly to the pump body 1, it can be ensured that the condensate can be quickly and effectively transferred to the outdoor unit 300 for evaporation treatment, reducing the risk of indoor water accumulation.

[0099] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The first housing 220 includes a bottom wall 221 and a plurality of side walls 222, the bottom wall 221 and the plurality of side walls 222 enclosing to form the water collection tank 201;

[0100] The bottom wall 221 is recessed with an installation groove 202, the pump body 1 is disposed in the installation groove 202, and the water inlet 102 of the pump body 1 is flush with the bottom wall 221.

[0101] In this embodiment, the first housing 220 consists of a bottom wall 221 and multiple side walls 222. These components together form a closed or semi-closed space for accommodating components such as the evaporator 210 and the pump body 1. This space also refers to the aforementioned water collection tank 201, used to collect condensate generated during the operation of the evaporator 210. The bottom wall 221 has a recessed mounting groove 202 for fixing the pump body 1. This design allows the pump body 1 to be embedded, saving space and increasing the compactness of the indoor unit 200 structure, which is beneficial for miniaturization design. The water inlet 102 of the pump body 1 is flush with the bottom wall 221, ensuring that condensate can flow smoothly into the pump body 1 and reducing the impact of water level differences.

[0102] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The outdoor unit 300 includes:

[0103] The second housing 310 is provided with a water storage tank 303, and the water pumping component 3 is positioned corresponding to the water storage tank 303.

[0104] A water receiving part 320 is disposed inside the second housing 310. The water receiving part 320 is connected to the water outlet 103 of the pump body 1. The water receiving part 320 is used to receive the condensate pumped by the pump body 1.

[0105] A condenser 330 is disposed inside the second housing 310. The water storage tank 303 is used to store the condensate that has not evaporated in the condenser 330. The water pumping assembly 3 is used to apply the condensate from the water storage tank 303 to the condenser 330.

[0106] In this embodiment, the second housing 310 is the outer shell of the outdoor unit 300, used to house and protect internal components such as the water receiving part 320 and the condenser 330. The water receiving part 320 is located inside the second housing 310 and is connected to the water outlet 103 of the pump body 1 in the indoor unit 200. Its main function is to receive and collect condensate from the pump body 1 and then guide it into the condenser 330. If the surface temperature of the condenser 330 is high enough, some of the condensate can evaporate directly upon contact with the condenser 330. A water storage tank 303 is provided inside the second housing 310 for temporarily storing condensate that has not completely evaporated from the condenser 330. That is, the water storage tank 303 is not only used to store condensate, but can also serve as a temporary storage pool. When the amount of condensate is large and the condenser 330 cannot evaporate it in time, it can be stored first and then subjected to secondary evaporation by the water pumping assembly 3 at an appropriate time.

[0107] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2The water receiving part 320 includes a base plate 321 and a plurality of side plates 322. The base plate 321 and the plurality of side plates 322 surround to form a water receiving groove 301. The water receiving groove 301 is connected to the water outlet 103 of the pump body 1. The base plate 321 is disposed toward the condenser 330 and is provided with a through hole 302.

[0108] In this embodiment, multiple side plates 322 extend upward around the base plate 321, forming a closed or semi-closed space, namely a water collection tank 301. The water collection tank 301 is directly connected to the outlet 103 of the pump body 1 and is used to receive condensate pumped from the pump body 1 of the indoor unit 200. The base plate 321 is positioned facing the condenser 330 and is provided with through holes 302 to guide the condensate in the water collection tank 301 to the condenser 330 for evaporation. In other words, during the operation of the air conditioner, the pump body 1 in the indoor unit 200 pumps the collected condensate through pipes to the water collection tank 301 of the outdoor unit 300. In the water collection tank 301, the condensate is guided to the condenser 330 through the through holes 302 on the base plate 321, and the high temperature on the surface of the condenser 330 promotes the rapid evaporation of the condensate.

[0109] Optionally, the number of through holes 302 can be set to multiple, and the multiple through holes 302 can be arranged in multiple rows along the length of the base plate 321. By setting multiple through holes 302, more condensate can be delivered to the condenser 330 at the same time, accelerating the cooling rate of the condenser 330 and further improving the energy efficiency of the air conditioner.

[0110] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The condenser 330 includes a first heat exchanger 331 and a second heat exchanger 332. The first water pumping impeller 31 of the water pumping assembly 3 is configured corresponding to the first heat exchanger 331, and the second water pumping impeller 32 of the water pumping assembly 3 is configured corresponding to the second heat exchanger 332.

[0111] In this embodiment, the first heat exchanger 331 is part of the condenser 330 and is used for heat exchange with the outside air to help the refrigerant release heat. The second heat exchanger 332 is another part of the condenser 330 and is also used for heat exchange with the outside air. It can be the same as or different from the first heat exchanger 331, depending on the actual needs and design goals. As can be seen from the above embodiment, the first water-discharging impeller 31 has a larger diameter and is set to correspond to the first heat exchanger 331. It can generate a strong centrifugal force to evenly spray the condensate from the water storage tank 303 onto the first heat exchanger 331, promoting the rapid evaporation of the condensate. The second water-discharging impeller 32 has a smaller diameter and is set to correspond to the second heat exchanger 332. It also sprays the condensate from the water storage tank 303 onto the second heat exchanger 332 to provide supplementation or fine spraying, ensuring that all condensate is effectively treated. By rationally allocating the working areas of the first water-pumping impeller 31 and the second water-pumping impeller 32, it is ensured that the condensate can evenly and effectively cover the entire surface of the condenser 330, thereby improving the evaporation efficiency.

[0112] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The air conditioner also includes:

[0113] The filter box 400 includes an inlet 410 and an outlet 420. The inlet 410 is connected to the outlet 103 of the pump body 1, and the outlet 420 is connected to the water receiving part 320 of the outdoor unit 300. The filter box 400 is used to receive the condensate pumped by the pump body 1, filter the condensate, and then deliver it to the water receiving part 320.

[0114] In this embodiment, the filter box 400 includes a filter chamber 430 and an inlet 410 and an outlet 420 connected to the filter chamber 430. The filter chamber 430 is filled with a filter medium, such as a filter screen, activated carbon, or other high-efficiency filter material, to remove small particles, dust, grease, and other impurities from the condensate. The inlet 410 is directly connected to the outlet 103 of the pump body 1 of the indoor unit 200 and is responsible for receiving the condensate pumped from the pump body 1 of the indoor unit 200. The outlet 420 is connected to the water receiving part 320 of the outdoor unit 300 and delivers the filtered clean condensate to the water receiving part 320, and then further guides it onto the condenser 330. In other words, during the operation of the air conditioner, the pump 1 in the indoor unit 200 pumps the collected condensate through pipes to the water inlet 410 of the filter box 400. After entering the filter box 400, the condensate passes through the built-in filter media to remove impurities and contaminants. The filtered condensate is then transported through the water outlet 420 to the water receiving section 320 of the outdoor unit 300, and then further directed to the condenser 330 for evaporation as needed. By filtering out impurities in the condensate, wear on subsequent components (such as the water pumping assembly 3 and the condenser 330) can be effectively reduced, extending the service life of the air conditioner.

[0115] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The air conditioner also includes:

[0116] A connecting pipe 500 connects the water outlet 420 and the water receiving part 320, wherein the height of the water outlet 420 is higher than the height of the water receiving part 320.

[0117] In this embodiment, the main function of the connecting pipe 500 is to connect the water outlet 420 of the filter box 400 to the water inlet 320 of the outdoor unit 300, forming a closed water flow channel so that the filtered condensate can flow smoothly into the water inlet 320. Since the water outlet 420 is located at a higher position, the condensate can automatically flow to the lower water inlet 320 under the action of gravity, without the need for additional power equipment (such as a pump), thereby reducing energy consumption. Moreover, compared with relying on pump force to drive the water flow, the natural flow method can reduce the risk of pipe blockage due to excessive pressure and improve the reliability of the air conditioning system.

[0118] In one embodiment of this utility model, reference is made to Figure 1 and Figure 2 The height difference between the water outlet 420 and the water receiving part 320 is not less than 5mm.

[0119] In this embodiment, by limiting the height difference between the water outlet 420 and the water receiving part 320 to not less than 5mm, it can be ensured that the condensate flows smoothly under the action of natural gravity, reducing water flow problems caused by improper pipe layout or installation errors.

[0120] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
