Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a window air conditioner. Background Technology

[0002] A window air conditioner is a thermostat installed on a window to regulate indoor temperature. In related technologies, window air conditioners typically use a rotating water pump to agitate water inside the casing, which is then blown onto the condenser by an outdoor fan, thereby improving the condenser's heat exchange efficiency. However, in actual operation, the amount of water blown onto the condenser is uneven, resulting in inconsistent moisture levels within the condenser and consequently affecting the heat exchange efficiency of the window air conditioner, leading to poor cooling performance. Summary of the Invention

[0003] This application discloses a window air conditioner with good heat exchange performance.

[0004] To achieve the above objectives, this application discloses a window air conditioner, comprising: The chassis is used to collect the condensate generated during the operation of the window air conditioner; An outdoor heat exchanger is installed above the chassis; An outdoor fan is provided, which is located near the outdoor heat exchanger and is used to drive outdoor air to flow through the outdoor heat exchanger for heat exchange. A water-pumping component is installed on the outdoor fan and is used to pump up the condensate on the chassis when it rotates with the outdoor fan. The outdoor fan is also used to blow at least a portion of the pumped condensate to the outdoor heat exchanger. The area of ​​the outdoor heat exchanger that receives less condensate is the water-scarce area, and the area that receives more condensate is the water-rich area. The top of the outdoor heat exchanger is provided with a condensate distribution component, which forms a water inlet trough. The condensate distribution component is used to collect the condensate agitated by the water pump into the water inlet trough. The water inlet trough extends along a first direction, and the bottom of the water inlet trough is provided with multiple through holes that extend to the top of the outdoor heat exchanger. The sum of the cross-sectional areas of the through holes located above the water-rich zone is less than the sum of the cross-sectional areas of the through holes located above the water-scarce zone.

[0005] Because the condensate distribution assembly is located at the top of the outdoor heat exchanger, and the water inlet trough extends along the first direction, the bottom of the trough has multiple through holes extending to the top of the outdoor heat exchanger. Furthermore, the sum of the cross-sectional areas of the through holes above the water-rich zone is less than the sum of the cross-sectional areas of the through holes above the water-scarce zone. Therefore, on the one hand, the condensate in the water inlet trough can be sprayed downwards onto the outdoor heat exchanger, where the evaporation of water carries away heat, effectively enhancing the heat exchange capacity of the outdoor heat exchanger, while simultaneously achieving condensate recycling.

[0006] On the other hand, along the first direction, the outdoor heat exchanger experiences a gradual decrease in humidity and a continuous increase in dryness due to the condensate sprayed by the water jetting components. Based on this, by ensuring that the sum of the cross-sectional areas of the through holes above the water-rich zone is less than the sum of the cross-sectional areas of the through holes above the water-scarce zone, the water-rich zone itself receives more liquid from the water jetting components, resulting in high overall humidity and sufficient water volume. The smaller total cross-sectional area of ​​all through holes above this zone reduces the overall liquid output, minimizing the need for additional water replenishment. This effectively prevents overload and overflow in the water-rich zone, and avoids localized water accumulation that could affect evaporative cooling efficiency.

[0007] On the other hand, areas with low water flow naturally receive less liquid and have drier surfaces. Consequently, the total cross-sectional area of ​​the through holes above is larger, resulting in a stronger overall liquid discharge capacity and the ability to replenish more liquid to these areas. Through the differentiated design of the two total flow areas, the water demand of different areas of the outdoor heat exchanger is precisely matched, gradually reducing the difference between dry and wet areas and making the overall water distribution of the heat exchanger more uniform.

[0008] Meanwhile, this structure can optimize the liquid flow distribution in the water inlet tank, allowing the liquid to be preferentially supplied to water-deficient areas, improving the recycling rate of condensate, ensuring that the evaporative heat dissipation effect of each part of the outdoor heat exchanger is more consistent, thereby improving the heat exchange of the outdoor heat exchanger. This can improve the problem of uneven condensate distribution on the surface of the outdoor heat exchanger, making the condensate coverage on the surface of the outdoor heat exchanger more uniform, strengthening the evaporative heat dissipation capacity of liquid water, and further improving the overall heat exchange performance and cooling effect of the window air conditioner.

[0009] Optionally, the water-rich area and the water-scarce area are arranged sequentially along the first direction; the plurality of through holes are arranged at intervals along the first direction, and the cross-sectional area of ​​the through holes gradually increases along the first direction.

[0010] Optionally, the condensate distribution assembly includes: A water-catching component protrudes from the outdoor heat exchanger along its thickness direction towards the side closest to the water-spraying component and is located on the path of the water-spraying component's projection of the condensate, for capturing the condensate projected out by the water-spraying component when it rotates. A water-guiding component is provided at the top of the outdoor heat exchanger, and the water-guiding component encloses and forms the water-guiding trough. The water-catching component is connected to the water-guiding trough.

[0011] Optionally, the water inlet includes: Blind spots; and, The hole section is connected to the blind section and the blind section and the hole section are arranged sequentially along the first direction, and a plurality of through holes are disposed at the bottom of the groove corresponding to the hole section.

[0012] Optionally, along the first direction, the length of the blind segment is L1, and the length of the hole segment is L2, where L1 < L2.

[0013] Alternatively, 1 / 5 < L1 / (L1+L2) < 1 / 2.

[0014] Optionally, the water-catching element includes multiple elements, which are arranged at intervals along a first direction. Each water-catching element is connected to the water-diverting channel, and there is a gap between two adjacent water-catching elements.

[0015] Optionally, the water-catching element includes: Capture the bottom wall of the water; An enclosing wall is provided around the periphery of the water-catching bottom wall, and the enclosing wall and the water-catching bottom wall enclose each other to form a water-catching trough, and the water-catching trough is connected to the water-diverting trough; Along the direction from the end of the water-catching trough away from the water-inlet to the end closer to the water-inlet, the bottom wall of the water-catching trough gradually slopes downward.

[0016] Optionally, the enclosing wall includes: First wall; The second wall is arranged sequentially and spaced apart from the first wall along the first direction; The third wall is connected between the first wall and the second wall and is located at the end of the water-catching bottom wall away from the water-inlet element; The height of the second wall is less than the height of the first wall.

[0017] Optionally, along the first direction, at least a portion of the bottom of the water inlet trough gradually slopes downward.

[0018] Optional: The minimum width of the gap is W, 10mm≤W≤40mm; And / or, The length of the water-catching element along the thickness direction of the outdoor heat exchanger is L, 10mm≤L≤60mm.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: In this application, since the condensate distribution component is located at the top of the outdoor heat exchanger, the water inlet trough extends along a first direction, and the bottom of the water inlet trough has multiple through holes extending to the top of the outdoor heat exchanger. Furthermore, the sum of the cross-sectional areas of the through holes located above the water-rich zone is less than the sum of the cross-sectional areas of the through holes located above the water-scarce zone. Therefore, on the one hand, the condensate in the water inlet trough can be sprayed downwards onto the outdoor heat exchanger, where the evaporation of water carries away heat, effectively enhancing the heat exchange capacity of the outdoor heat exchanger, while simultaneously achieving condensate recycling.

[0020] On the other hand, along the first direction, the outdoor heat exchanger experiences a gradual decrease in humidity and a continuous increase in dryness due to the condensate sprayed by the water jetting components. Based on this, by ensuring that the sum of the cross-sectional areas of the through holes above the water-rich zone is less than the sum of the cross-sectional areas of the through holes above the water-scarce zone, the water-rich zone itself receives more liquid from the water jetting components, resulting in high overall humidity and sufficient water volume. The smaller total cross-sectional area of ​​all through holes above this zone reduces the overall liquid output, minimizing the need for additional water replenishment. This effectively prevents overload and overflow in the water-rich zone, and avoids localized water accumulation that could affect evaporative cooling efficiency.

[0021] On the other hand, areas with low water flow naturally receive less liquid and have drier surfaces. Consequently, the total cross-sectional area of ​​the through holes above is larger, resulting in a stronger overall liquid discharge capacity and the ability to replenish more liquid to these areas. Through the differentiated design of the two total flow areas, the water demand of different areas of the outdoor heat exchanger is precisely matched, gradually reducing the difference between dry and wet areas and making the overall water distribution of the heat exchanger more uniform.

[0022] Meanwhile, this structure can optimize the liquid flow distribution in the water inlet tank, allowing the liquid to be preferentially supplied to water-deficient areas, improving the recycling rate of condensate, ensuring that the evaporative heat dissipation effect of each part of the outdoor heat exchanger is more consistent, thereby improving the heat exchange of the outdoor heat exchanger. This can improve the problem of uneven condensate distribution on the surface of the outdoor heat exchanger, making the condensate coverage on the surface of the outdoor heat exchanger more uniform, strengthening the evaporative heat dissipation capacity of liquid water, and further improving the overall heat exchange performance and cooling effect of the window air conditioner.

[0030] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0031] A window air conditioner is a temperature regulator installed on a window to regulate indoor temperature. In related technologies, window air conditioners typically utilize the rotational motion of a water-pumping component to agitate water inside the casing, which is then blown onto the condenser by an outdoor fan, thereby improving the condenser's heat exchange efficiency. However, in actual operation, the amount of water blown onto the condenser is uneven, resulting in inconsistent condenser moisture levels, which in turn affects the heat exchange efficiency of the window air conditioner, leading to poor cooling performance. Therefore, this application provides a novel window air conditioner to address these problems.

[0032] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0033] Figure 1 This is a schematic diagram of the structure of a window air conditioner 100 according to an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of the structure of the window air conditioner 100 from another perspective.

[0034] See Figure 1 and Figure 2 The window air conditioner 100 includes a housing 1, which has an outdoor air inlet 11, an outdoor air outlet 12, an indoor air inlet 13, and an indoor air outlet 14.

[0035] The casing 1 can be made of plastic, but other possible materials are also possible; this embodiment does not limit this. The shape of the casing 1 can be as follows: Figure 1 The rectangular parallelepiped shown is, of course, the housing 1 can also be other possible shapes, and this embodiment does not limit it.

[0036] The outdoor air inlet 11 can be located on the top surface of the housing 1, the outdoor air outlet 12 can be located at the rear of the housing 1, and the indoor air inlet 13 and the indoor air outlet 14 can both be located at the front of the housing 1.

[0037] Of course, the outdoor air inlet 11, outdoor air outlet 12, indoor air inlet 13 and indoor air outlet 14 can also be located in other possible positions on the casing 1, and this embodiment does not limit this.

[0038] It should be noted that the top surface of the casing 1 mentioned above refers to the surface of the casing 1 facing vertically upwards when the window air conditioner 100 is normally installed and in use. The rear surface of the casing 1 refers to the surface of the window air conditioner 100 facing outdoors after it is installed in the window. The front surface of the casing 1 refers to the surface of the window air conditioner 100 facing indoors after it is installed in the window.

[0039] In some embodiments, see Figure 1 and Figure 3 , Figure 3 yes Figure 1 Window air conditioner 100 in Figure 1 The structural diagram with part of the casing 1 omitted from the view shows that the window air conditioner 100 includes an indoor heat exchanger 2, which is disposed inside the casing 1.

[0040] By placing the indoor heat exchanger 2 inside the casing 1, on the one hand, the casing 1 can protect the indoor heat exchanger 2, making the environment in which the indoor heat exchanger 2 is located safer, thereby extending the service life of the indoor heat exchanger 2. On the other hand, the casing 1 can regulate and guide the air, directing the indoor air to flow orderly through the indoor heat exchanger 2, allowing the air to fully contact the indoor heat exchanger 2, thereby improving heat exchange efficiency and ensuring the temperature control effect of the window air conditioner 100.

[0041] Specifically, the aforementioned indoor heat exchanger 2 can be an evaporator.

[0042] In some embodiments, see Figure 1 , Figure 3 and Figure 4 , Figure 4 yes Figure 3 An exploded view of a window air conditioner 100, which also includes an indoor fan 3 disposed inside the casing 1, used to drive indoor air to enter the casing 1 from the indoor air inlet 13, exchange heat with the indoor heat exchanger 2, and then flow back into the room from the indoor air outlet 14.

[0043] By installing an indoor fan 3 inside the casing 1, the indoor fan 3 can actively drive the indoor air circulation, causing air to continuously flow from the indoor air inlet 13 into the casing 1 and pass through the indoor heat exchanger 2, thereby ensuring sufficient contact and heat exchange between the air and the indoor heat exchanger 2. On the other hand, the heat-exchanged air can smoothly flow back into the room from the indoor air outlet 14, thereby accelerating the overall temperature regulation speed of the indoor air and improving the performance of the window air conditioner 100.

[0044] Meanwhile, the casing 1 can protect and limit the indoor fan 3, reduce the interference of external factors on the operation of the fan, and ensure its stable operation.

[0045] Specifically, the indoor fan 3 can be a centrifugal fan.

[0046] In some embodiments, see Figure 2 and Figure 5 , Figure 5 yes Figure 2 This is a schematic diagram of a window air conditioner 100, omitting part of the casing 1. The window air conditioner 100 includes an outdoor heat exchanger 4, which is disposed inside the casing 1. Specifically, in some embodiments, see... Figure 7 The housing 1 includes a chassis 15, which is used to collect the condensate generated during the operation of the window air conditioner 100. The outdoor heat exchanger 4 is located above the chassis 15.

[0047] By housing the outdoor heat exchanger 4 within the casing 1, the casing 1 provides protection for the outdoor heat exchanger 4, reducing direct corrosion from outdoor dust, debris, and rainwater, thus lowering the probability of failure and extending its service life. Furthermore, the casing 1 restricts airflow on the outdoor side, guiding outdoor air to flow directly through the outdoor heat exchanger 4, ensuring sufficient contact between the airflow and its surface, thereby improving heat exchange efficiency and guaranteeing the overall cooling performance of the window air conditioner 100.

[0048] Among them, the outdoor heat exchanger 4 can be a condenser.

[0049] In some embodiments, see Figure 3 The window air conditioner 100 includes a compressor 8, which is disposed inside the casing 1 and connected to the outdoor heat exchanger 4 and the indoor heat exchanger 2, for transferring heat from the indoor heat exchanger 2 to the outdoor heat exchanger 4.

[0050] By connecting the compressor 8 to the outdoor heat exchanger 4 and the indoor heat exchanger 2, the compressor 8 can achieve refrigerant circulation, continuously transferring the heat absorbed by the indoor heat exchanger 2 to the outdoor heat exchanger 4 for dissipation, thereby completing the transfer of indoor heat to the outside, and thus ensuring that the window air conditioner 100 can continuously and stably achieve the cooling function.

[0051] In some embodiments, see Figure 6 The window air conditioner 100 includes an outdoor fan 5, which is located near the outdoor heat exchanger 4 and is used to drive outdoor air to flow through the outdoor heat exchanger 4 for heat exchange. Specifically, the outdoor fan 5 is located inside the casing 1 and is used to drive outdoor air to enter the casing 1 from the outdoor air inlet 11, exchange heat with the outdoor heat exchanger 4, and then flow back to the outside from the outdoor air outlet 12.

[0052] Since the outdoor fan 5 can actively drive the outdoor air circulation, guide the air to flow in from the outdoor air inlet 11 and fully pass over the outdoor heat exchanger 4, efficiently remove the heat generated by the heat exchange, and then discharge the air after heat exchange through the outdoor air outlet 12, thereby improving the heat dissipation efficiency of the outdoor heat exchanger 4 and ensuring the stable operation of the window air conditioner 100 in cooling mode.

[0053] In some embodiments, see Figure 5 , Figure 6 and Figure 7 , Figure 6 yes Figure 5 An exploded view of a window-type air conditioner. Figure 7 yes Figure 5 The window air conditioner 100 shown in the diagram is a structural schematic diagram from another perspective after some of its structure has been omitted. The window air conditioner 100 includes a water pumping component 6, which is disposed on the outdoor fan 5 and is used to pump up the condensate in the casing 1 when it rotates with the outdoor fan 5. Specifically, it is used to pump up the condensate on the chassis 15 when it rotates with the outdoor fan 5. The outdoor fan 5 is also used to blow at least a portion of the pumped condensate to the outdoor heat exchanger 4. The area of ​​the outdoor heat exchanger 4 that receives less condensate is the water-scarce area 41, and the area that receives more condensate is the water-rich area 42.

[0054] Since the water-collecting component 6 is located on the outdoor fan 5, when the outdoor fan 5 rotates, the water-collecting component 6 can rotate along with the outdoor fan 5. When the water-collecting component 6 rotates along with the outdoor fan 5, it can agitate the condensate inside the casing 1. When the water-collecting component 6 agitates the condensate inside the casing 1, the centrifugal force of the water-collecting component 6 and the airflow generated by the outdoor fan 5 can be used to blow the condensate towards the outdoor heat exchanger 4. After the condensate adheres to the surface of the outdoor heat exchanger 4, it can enhance heat dissipation through evaporation, thereby improving the heat exchange effect of the outdoor heat exchanger 4.

[0055] It is understandable that when the water pumping component 6 rotates, a portion of its structure just passes the condensate storage location inside the casing 1, resulting in a large amount of condensate adhering to that portion of the structure. As the water pumping component 6 continues to rotate, the amount of condensate adhering to that portion of the structure will decrease under the action of its own centrifugal force and the airflow generated by the outdoor fan 5. This will cause the amount of condensate received by different areas of the outdoor heat exchanger 4 to be different, thus naturally forming a water-deficient area 41 with less water and a water-rich area 42 with more water in the outdoor heat exchanger 4.

[0056] For example, with Figure 7 Taking the medium-angle view as an example, assuming that the water pump 6 rotates counterclockwise with the outdoor fan 5, then obviously, more condensate will be blown to the right side of the outdoor heat exchanger 4, while less condensate will be blown to the left side of the outdoor heat exchanger 4, resulting in a water-deficient area 41 with less water on the left side of the outdoor heat exchanger 4 and a water-rich area 42 with more water on the right side.

[0057] It is understandable that when there is a water-deficient area 41 in the outdoor heat exchanger 4, the heat exchange efficiency of that part of the outdoor heat exchanger 4 will not be ideal, which will in turn lead to an unsatisfactory heat exchange effect of the entire outdoor heat exchanger 4, thus affecting the cooling effect of the entire window air conditioner 100.

[0058] Among them, see Figure 7 and Figure 8 , Figure 8 yes Figure 7 The diagram shows the structure of the water-spraying component 6 and the outdoor fan 5. The water-spraying component 6 can be a ring-shaped structure. The water-spraying component 6 can be integrally formed with the outdoor fan 5. Of course, the water-spraying component 6 and the outdoor fan 5 can also be separate structures. This embodiment does not limit this.

[0059] It should be noted that the condensate can come from the moisture that condenses when the air is cooled. It can be collected inside the casing 1 and stored. Specifically, it can be collected on the chassis 15 and stored for the water pumping unit 6 to be used in a cycle.

[0060] The term "condensate" can be interpreted broadly. Specifically, condensate can refer to coolant added artificially, or a mixture of coolant and condensate. This embodiment does not limit this interpretation.

[0061] To ensure that the water-pumping component 6 can successfully pump up the condensate inside the casing 1, in some embodiments, see... Figure 7 and Figure 9 , Figure 9 yes Figure 7 A schematic diagram of the structure of the chassis 15 shows that the housing 1 includes the chassis 15, and a liquid storage tank 151 is provided on the chassis 15. The liquid storage tank 151 is located on the rotation trajectory of the water spraying component 6.

[0062] By setting a liquid storage tank 151 on the chassis 15 of the casing 1 and arranging the liquid storage tank 151 on the rotation trajectory of the water pumping component 6, on the one hand, the liquid storage tank 151 can centrally collect the condensate generated inside the casing 1, realizing centralized storage of condensate and preventing condensate from flowing randomly inside the casing 1, thus keeping the inside of the equipment clean. On the other hand, when the water pumping component 6 rotates, it can directly contact the condensate in the liquid storage tank 151, stably completing the water pumping operation, ensuring that the condensate is continuously lifted and transported to the outdoor heat exchanger 4, thereby ensuring stable heat dissipation and allowing the window air conditioner 100 to operate normally for a long time.

[0063] Considering that the presence of a water-deficient zone 41 in the outdoor heat exchanger 4 will affect the cooling effect of the entire window air conditioner 100, in order to avoid or minimize this situation, in some embodiments, see... Figure 7 and Figure 10 , Figure 10 yes Figure 7A schematic diagram of the structure of the condensate distribution assembly 7 is shown. The outdoor heat exchanger 4 includes the condensate distribution assembly 7, which includes a water trap 71. The water trap 71 is located along the thickness direction of the outdoor heat exchanger 4 (exemplarily, it can be...). Figure 7 The outdoor heat exchanger 4 protrudes towards the side close to the water pumping component 6 in the Y-axis direction and is located on the path of the water pumping component 6 to throw condensate, in order to capture the condensate thrown out when the water pumping component 6 rotates.

[0064] Since the water-catching element 71 protrudes from the outdoor heat exchanger 4 along the thickness direction towards the side closest to the water-pumping element 6 and is located on the path of the water-pumping element 6 for throwing condensate, when the water-pumping element 6 follows the rotation of the outdoor fan 5 and throws condensate outward along the rotational tangent of the water-pumping element 6, the water-catching element 71 can effectively intercept and capture the condensate thrown out by the water-pumping element 6, reducing the direct scattering and loss of condensate and improving the utilization rate of condensate. On the other hand, the captured condensate can be uniformly collected, providing a source for subsequent replenishment of water to the water-deficient area 41 of the outdoor heat exchanger 4, thereby providing a basis for improving the problem of uneven condensate distribution on the surface of the outdoor heat exchanger 4.

[0065] It should be noted that the thickness direction of the outdoor heat exchanger 4 can be the same as the depth direction of the casing 1. The depth direction of the casing 1 refers to the direction from the front of the casing 1 towards the interior to the rear of the casing 1 towards the exterior when the window air conditioner 100 is installed and in normal use.

[0066] In some embodiments, see Figure 7 and Figure 10 The condensate distribution assembly 7 includes a water inlet 72, which is connected to a water catcher 71 and is used to receive the condensate captured by the water catcher 71.

[0067] By setting a water guide 72 connected to the water catcher 71, on the one hand, the water guide 72 can smoothly receive the condensate collected by the water catcher 71, preventing the condensate from splashing and leaking everywhere. On the other hand, the water guide 72 can form a directional flow of condensate, so that the condensate is transported downward in an orderly manner, ensuring that the condensate flows stably to the subsequent structure, and providing reliable transportation conditions for the balanced distribution of water in the outdoor heat exchanger 4.

[0068] In some embodiments, see Figure 7 and Figure 10 The condensate distribution assembly 7 includes a water collection element 73, which is disposed on and communicates with the water inlet element 72. The water inlet element 72 is also used to guide the received condensate into the water collection element 73. The water collection element 73 has a drain outlet 730 facing the side of the water pumping element 6 near the water-scarce area 41, so as to drain the condensate in the water collection element 73 to the water pumping element 6.

[0069] By assembling a water collecting component 73 that is connected to the water inlet component 72, the water inlet component 72 can firstly transport the condensate collected and guided by the water trap 71 to the interior of the water collecting component 73, where the water collecting component 73 centrally stores the recovered condensate, preventing the recovered condensate from dripping or scattering randomly. At the same time, it can buffer the flow rate of the condensate, ensuring a more stable condensate delivery.

[0070] Secondly, the water collecting component 73 has a drain outlet 730, which is precisely oriented towards the side of the water pumping component 6 closest to the water-deficient zone 41. Therefore, the water collecting component 73 can directionally and centrally discharge the temporarily stored condensate to the side of the water pumping component 6 closest to the water-deficient zone 41. Subsequently, as the water pumping component 6 rotates synchronously with the outdoor fan 5, it can carry this supplementary condensate and spray it again onto the water-deficient zone 41 of the outdoor heat exchanger 4. This achieves secondary distribution of excess condensate, compensates for the insufficient liquid supply to the water-deficient zone 41, reduces the dryness and wetness difference between the water-deficient zone 41 and the water-rich zone 42, makes the condensate coverage on the surface of the outdoor heat exchanger 4 more uniform, enhances the heat dissipation capacity of liquid water evaporation, and further improves the overall heat exchange performance and cooling effect of the window air conditioner 100.

[0071] Furthermore, since the drain outlet 730 can direct and concentrate the temporarily stored condensate to the side of the water pumping component 6 near the water-deficient area 41, and the water pumping component 6 can rotate with the outdoor fan 5, the water pumping component 6 can disperse the condensate discharged from the drain outlet 730 and break it into small diameter droplets, which greatly increases the heat exchange area of ​​the condensate molecules, causing them to evaporate almost instantly after reaching the outdoor heat exchanger 4. This can further improve the heat exchange effect of the outdoor heat exchanger 4, and thus further improve the overall heat exchange performance and cooling effect of the window air conditioner 100.

[0072] In some embodiments, see Figure 7 and Figure 10 The water-catching element 71 includes a plurality of water-catching elements 71 along a first direction (exemplarily, it can be...). Figure 7 Arranged at intervals along the X-axis, each water-catching element 71 is connected to a water-drawing element 72. Specifically, each water-catching element 71 is connected to a water-drawing channel 721 of the water-drawing element 72, and there is a gap 710 between two adjacent water-catching elements 71.

[0073] By arranging multiple water-catching elements 71 at intervals along a first direction, with each water-catching element 71 connected to a water-guiding element 72, on the one hand, the multiple sets of water-catching elements 71 can expand the condensate interception range, fully catching the condensate projected by the water-spraying element 6, and improving the condensate collection efficiency. On the other hand, the gap 710 set between two adjacent water-catching elements 71 allows the sprayed condensate to pass smoothly through and reach the top of the water-catching element 71, enabling the water-catching element 71 to effectively capture it, thereby further improving the condensate collection efficiency of the water-catching element 71.

[0074] In some embodiments, see Figure 7 The first direction (exemplarily, can be) Figure 7 The width direction of housing 1 is (X-axis direction).

[0075] When the first direction is the width direction of the housing 1, multiple water-catching components 71 can be arranged at intervals along the width direction of the housing 1. When multiple water-catching components 71 are arranged at intervals along the width direction of the housing 1, compared with other arrangement directions, on the one hand, the condensate ejected by the water-spraying component 6 mainly diffuses along the width direction of the housing 1. This arrangement can accurately match the overall distribution range of the condensate and maximize the coverage of the liquid-catching area. Compared with longitudinal and oblique arrangement, it can reduce the escape of condensate and improve the overall liquid-catching efficiency.

[0076] On the other hand, the arrangement along the width direction can fit the overall shape of the outdoor heat exchanger 4, resulting in a more regular structural layout that does not additionally occupy the depth direction of the casing 1 (for example, it can be...). Figure 7 (in the Y-axis direction) or the height direction (for example, it can be...) Figure 7 A finite space (in the Z-axis direction).

[0077] At the same time, multiple gaps 710 between adjacent water-catching components 71 can be set in the direction of condensate splashing, reducing the resistance of condensate flow and further preventing liquid accumulation and overflow.

[0078] Of course, the first direction can also be other possible directions, and this embodiment does not limit this.

[0079] It should be noted that the height direction of the aforementioned casing 1 refers to the vertical direction extending up and down along the casing 1 in the normal installation and use state of the window air conditioner 100, and simultaneously perpendicular to the depth and width directions. The width direction of the aforementioned casing 1 refers to the horizontal direction extending along the left and right sides of the casing 1 in the normal installation and use state of the window air conditioner 100, and simultaneously perpendicular to the depth and height directions.

[0080] In some embodiments, see Figure 11 , Figure 11 yes Figure 10 The condensate distribution component 7 is shown in a schematic diagram from another perspective. The minimum width of the gap 710 is W, where 10mm ≤ W ≤ 40mm.

[0081] If the minimum width W of the gap 710 is less than 10mm, the gap space is narrow, and splashed condensate water is easily blocked, stagnated, and overflows at this point, making it difficult for the condensate water to reach the upper part of the water-catching element 71, thus affecting the efficiency of the water-catching element 71 in capturing condensate water.

[0082] If the minimum width W of the gap 710 is greater than 40mm, the distance between adjacent water-catching elements 71 is too large, and a large amount of ejected condensate will escape directly from the wide gap and cannot be effectively captured, which will greatly reduce the condensate recovery rate and is not conducive to the subsequent water replenishment adjustment of the water-deficient zone 41 of the outdoor heat exchanger 4.

[0083] Based on this, by setting the minimum width W of the gap 710 to 10mm ≤ W ≤ 40mm, on the one hand, when W is not less than 10mm, the gap 710 has sufficient passage space to ensure that splashed condensate water can pass smoothly and avoid condensate water being blocked, accumulating, and overflowing at the gap. On the other hand, when W is not greater than 40mm, the excessive opening of the gap can be limited to ensure that the spacing between adjacent water-catching elements 71 is reasonable. This prevents a large amount of condensate water from escaping directly and not being effectively captured due to excessively wide gaps, while maintaining the overall arrangement density of the water-catching elements 71 to ensure a comprehensive liquid capture effect. This size range takes into account the needs of condensate water passage and condensate water collection, ensuring the stable operation of the condensate water distribution component 7.

[0084] Specifically, the minimum width of the gap 710 can be 10mm, 15mm, 20mm, 25mm or 40mm, etc., as long as 10mm≤W≤40mm. This embodiment will not list them one by one.

[0085] In some embodiments, see Figure 7 and Figure 11 The water trap 71 is along the thickness direction of the outdoor heat exchanger 4 (exemplarily, it can be...). Figure 11 The length of the Y-axis is L, 10mm≤L≤60mm.

[0086] If the length L of the water catcher 71 along the thickness direction of the outdoor heat exchanger 4 is less than 10mm, the effective liquid-facing area of ​​the water catcher 71 is insufficient, making it difficult to fully receive the condensate thrown in. The condensate is easy to leak from the edge, and the liquid-catching effect is greatly reduced.

[0087] If the length L of the water trap 71 along the thickness direction of the outdoor heat exchanger 4 is greater than 60mm, the extension size of the water trap 71 is too large. This will not only occupy additional internal space of the casing 1, but also significantly obstruct the airflow, increase wind resistance, and affect the normal ventilation and heat exchange of the outdoor heat exchanger 4.

[0088] Therefore, when the length L satisfies 10mm≤L≤60mm, the water-catching component has sufficient liquid-facing area to stably intercept and collect condensate, ensuring efficient liquid collection. At the same time, it does not excessively obstruct the airflow channel, keeping the wind resistance within a reasonable range, balancing condensate collection and air circulation requirements, and ensuring stable operation of the heat exchange system.

[0089] Specifically, L can be 10mm, 15mm, 20mm, 25mm, 35mm, 50mm or 60mm, etc., as long as 10mm≤L≤60mm. This embodiment will not list them all here.

[0090] The shape of the aforementioned water-catching component 71 can be as follows: Figure 11 The shape shown is rectangular. Of course, the water-catching element 71 can also be other possible shapes, such as semi-circular, V-shaped, honeycomb grid or grid shape. This embodiment does not limit the shape of the water-catching element 71.

[0091] Without an absorbent coating, condensate easily slips and splashes upon contact with the surface of the water-catching element 71, resulting in some condensate being lost before it can be collected. Therefore, to improve the ability of the water-catching element 71 to capture condensate, in some embodiments, an absorbent coating can be provided on the water-catching element 71. Adding an absorbent coating allows for the rapid adsorption of splashed condensate, reducing the probability of splashing and rolling, and further improving the condensate collection rate. Furthermore, it slows down the flow rate of the condensate, allowing it to flow smoothly into the water-guiding element 72, preventing overflow caused by a sudden surge of condensate.

[0092] Meanwhile, the coating allows condensate to spread evenly on the surface of the water catcher 71, ensuring that the condensate flows downward continuously and stably, providing a sufficient and continuous liquid source for the subsequent water replenishment and adjustment of the outdoor heat exchanger 4, and improving the overall reliability of the condensate distribution assembly 7.

[0093] Specifically, the water-absorbing coating can be a hydrophilic resin coating, a water-absorbing fiber coating, or a porous ceramic coating. This type of coating has good hydrophilic and water-absorbing properties, can firmly adhere to the surface of the water-catching component 71, is not easy to fall off or age, and can play a stable role in adsorbing and guiding liquid for a long time.

[0094] In some embodiments, see Figure 10 and Figure 12 , Figure 12 yes Figure 10 The enlarged view at position A shows that the water-catching component 71 includes a water-catching bottom wall 711 and an enclosing wall 712. The enclosing wall 712 is disposed around the water-catching bottom wall 711, and the enclosing wall 712 and the water-catching bottom wall 711 enclose each other to form a water-catching trough 7110. The water-catching trough 7110 is connected to the water-drawing component 72. Specifically, the water-catching trough 7110 is connected to the water-drawing trough 721.

[0095] If the water-catching component 71 is only a flat plate structure, the collected condensate is prone to sliding off the sides and splashing away. Therefore, by setting an enclosing wall 712 around the perimeter of the bottom wall 711, the enclosing wall 712 and the bottom wall 711 enclose and form a water-catching trough 7110. On the one hand, the enclosing wall 712 can contain and restrain the condensate falling into the water-catching trough 7110, effectively preventing condensate from overflowing from the side of the water-catching component 71, reducing condensate loss, and increasing the amount of condensate collected. On the other hand, the water-catching trough 7110 can temporarily store the collected condensate, buffering the impact of condensate and preventing turbulence caused by excessively fast condensate flow.

[0096] Meanwhile, the water collection tank 7110 is directly connected to the water inlet 72, and the condensate in the tank can flow into the water inlet 72 in an orderly and smooth manner, ensuring the continuous and stable flow of condensate and providing a reliable liquid transport foundation for the subsequent condensate distribution process.

[0097] In some embodiments, see Figure 11 , Figure 12 and Figure 13 , Figure 13 yes Figure 11 A cross-sectional view of the condensate distribution assembly 7 at position BB, along the end of the water trap 7110 away from the water inlet 72 (exemplarily, it can be...). Figure 13 From the left end of the central water trap 7110 to the end near the water inlet 72 (exemplarily, it can be the left end of the central water trap 7110 to the end near the water inlet 72). Figure 13 The bottom wall of the water-catching tank 711 gradually slopes downwards towards the water-inlet 72 (right end of the water-catching tank 7110).

[0098] Along the water-catching trough 7110 from the end away from the water-inlet 72 to the end near the water-inlet 72, the bottom wall 711 of the water-catching trough has a downward sloping structure.

[0099] On the one hand, the inclined structure allows the condensate to flow automatically towards the water inlet 72 using its own gravity, eliminating the need for additional flow-guiding components and simplifying the overall structure. On the other hand, the continuous slope ensures smooth condensate flow, preventing condensate from stagnating or accumulating in the condensate tank 7110. This ensures that the collected condensate flows quickly and completely into the water inlet 72, guaranteeing continuous and efficient condensate delivery and supporting the stable operation of subsequent water distribution.

[0100] In some embodiments, see Figure 7 and Figure 12 The enclosing wall 712 includes a first wall 7121, a second wall 7122, and a third wall 7123, wherein the second wall 7122 and the first wall 7121 are along a first direction (exemplarily, it can be...). Figure 12The third wall 7123 is connected between the first wall 7121 and the second wall 7122 and is located at the end of the water-catching bottom wall 711 away from the water-introducing element 72 (exemplarily, it can be...). Figure 12 (Left end of the bottom wall 711 in the middle of the fishing boat).

[0101] Since the second wall 7122 and the first wall 7121 are spaced apart and arranged sequentially along the first direction, and the third wall 7123 is connected between the first wall 7121 and the second wall 7122 and is located at the end of the water-catching bottom wall 711 away from the water-inlet member 72, the third wall 7123 forms a closed enclosure for this end of the water-catching tank 7110, which can prevent condensate from splashing out from this end, reduce the loss of condensate, and ensure that the collected condensate is retained in the water-catching tank 7110 and can flow into the water-inlet member 72 through the end close to the water-inlet member 72.

[0102] In some embodiments, see Figure 7 and Figure 12 The water-rich area 42 and the water-poor area 41 are arranged sequentially along the first direction, and the height of the second wall 7122 is less than the height of the first wall 7121.

[0103] By making the height of the second wall 7122 less than the height of the first wall 7121, the lower height of the second wall 7122 places it below the droplet projection path of the water-spraying component 6, allowing the projected droplets to smoothly pass over the second wall 7122 and fall into the water-collecting tank 7110, significantly improving the efficiency of condensate collection. The higher height of the first wall 7121, situated on the droplet projection path of the water-spraying component 6, effectively blocks the droplets, preventing condensate from splashing outwards. The overall structure, combined with the difference in wall height, adapts to the droplet projection trajectory, maximizing the collection of condensate from the target area and ensuring stable water collection operations.

[0104] In some embodiments, see Figure 10 The water-guiding element 72 encloses to form a water-guiding channel 721, and the water-guiding channel 721 is along a first direction (exemplarily, it can be...). Figure 10 Extending along the X-axis, the water-catching component 71 is connected to the water-drawing trough 721, and the bottom 7211 of the water-drawing trough 721 is lower than the bottom wall 711 of the water-catching component.

[0105] By extending the water inlet channel 721 along the first direction, each water-catching element 71 is connected to the water inlet channel 721, and the bottom 7211 of the water inlet channel 721 is lower than the bottom wall 711 of the water-catching element. On the one hand, the water inlet channel 721 extends along the first direction, and can be connected one-to-one with multiple water-catching elements 71 arranged at intervals along this direction, so as to uniformly receive the condensate collected by all water-catching elements 71, realize the centralized collection of liquid flow from multiple points, and make the overall flow path regular and orderly.

[0106] On the other hand, the bottom 7211 of the water inlet trough 721 is lower than the bottom wall 711 of the water catcher, creating a height difference. The condensate in the water catcher trough 7110 can automatically flow downwards into the water inlet trough 721 by gravity, improving the efficiency of liquid flow and preventing condensate from stagnating and accumulating at the connection point. At the same time, the elongated water inlet trough 721 can buffer the impact of the buffer flow, balance the liquid level at various points, further prevent condensate from overflowing, and ensure stable flow of condensate throughout the process.

[0107] In some embodiments, see Figure 14 and Figure 15 , Figure 14 yes Figure 11 A schematic diagram of the condensate distribution component 7 from another perspective. Figure 15 yes Figure 14 A cross-sectional view of the condensate distribution component 7 at the CC position, along the first direction (exemplarily, it can be...). Figure 5 (in the negative direction of the X-axis), at least part of the bottom 7211 of the water inlet trough 721 gradually slopes downward.

[0108] By causing at least a portion of the bottom 7211 of the water inlet trough 721 to gradually slope downwards along the first direction, on the one hand, this inclined structure, relying on the height difference, allows the condensate in the water inlet trough 721 to continuously flow forward under gravity, effectively preventing the condensate from stagnating or accumulating locally at the bottom 7211. On the other hand, the gradual slope can smoothly increase the liquid flow velocity, disperse the water flow from multiple water-catching elements 71, prevent condensate from congesting or overflowing in the water inlet trough 721, and ensure that the condensate is transported downstream in an orderly manner along the first direction, making the entire flow guiding system operate more stably.

[0109] Wherein, "at least part of the tank bottom 7211 gradually slopes downward" means that the entire section of the tank bottom 7211 slopes continuously downward from one end to the other along the first direction. Alternatively, a section of the tank bottom 7211 may be partially configured to slope downward along the first direction, while the remaining sections of the tank bottom 7211 remain horizontal.

[0110] In some embodiments, see Figure 14 and Figure 15 The water collection component 73 is connected to the bottom of the tank 7211 along the first direction (exemplarily, it can be...). Figure 14 The lower end (in the negative direction of the X-axis) (for example, could be...) Figure 14 (Left end of the bottom of the middle tank 7211).

[0111] By connecting the water collection component 73 to the lower end of the tank bottom 7211 along the first direction, on the one hand, combined with the downward sloping structure of the tank bottom 7211, the condensate continuously gathers towards the lower end by gravity and can flow smoothly into the water collection component 73 without any residual liquid. On the other hand, this layout follows the liquid flow direction, reduces water flow back and forth and stagnation, improves the condensate collection efficiency, ensures that the condensate in the water inlet tank 721 is fully collected, and allows the entire water guiding and collecting system to operate continuously and stably.

[0112] In some embodiments, see Figure 16 , Figure 16 This is a schematic diagram of another condensate distribution component 7 provided in an embodiment of this application. A capillary structure 7212 is provided in the water inlet tank 721. The capillary structure 7212 is used to attract the condensate in the water inlet tank 721 along a first direction (exemplarily, it can be...). Figure 16 (Flow in the negative direction of the X-axis).

[0113] By setting a capillary structure 7212 in the water inlet tank 721, on the one hand, when the liquid volume in the water inlet tank 721 is small and the gravity drive is insufficient, the capillary structure can actively adsorb and pull the condensate to flow forward, avoiding a small amount of condensate adhering to the bottom of the tank 7211 and remaining there, ensuring that the liquid flow can still be transported normally at low liquid levels.

[0114] On the other hand, the capillary structure can help guide the water flow, and together with the inclined structure of the bottom of the tank 7211, it forms a double guiding effect, further accelerating the flow rate of condensate, preventing local accumulation of condensate and overflow of the tank, and improving the overall stability of water collection and guiding.

[0115] In some embodiments, see Figure 10 The water collection component 73 includes a water collection box 731 and a drain pipe 732. The water collection box 731 is disposed on and connected to the water inlet component 72. One end of the drain pipe 732 is connected to the water collection box 731, and the other end forms a drain outlet 730.

[0116] Since the water collection box 731 is located on and connected to the water inlet 72, the water collection box 731 can temporarily store the condensate collected in the water inlet tank 721, buffer the water flow impact, balance the liquid level, and prevent the water from flowing directly into the drain pipe 732 and causing gushing or splashing.

[0117] By connecting one end of the drain pipe 732 to the water collection box 731 and forming a drain outlet 730 at the other end, the drain pipe 732 directs the collected condensate through the drain outlet 730 to the water pumping component 6. As the water pumping component 6 rotates synchronously with the outdoor fan 5, it carries this additional condensate and sprays it again onto the water-deficient zone 41 of the outdoor heat exchanger 4. This achieves secondary distribution of excess condensate, compensating for insufficient liquid supply in the water-deficient zone 41, reducing the dryness / wetness difference between the water-deficient zone 41 and the water-rich zone 42, resulting in more uniform condensate coverage on the surface of the outdoor heat exchanger 4, enhancing the evaporative cooling capacity of liquid water, and further improving the overall heat exchange performance and cooling effect of the window air conditioner 100.

[0118] By setting up the drain pipe 732, on the one hand, the condensate can be accurately guided to the target position of the water spraying component 6 under the guidance of the drain pipe 732, thereby ensuring that the water spraying component 6 continuously and stably obtains a water source. On the other hand, the drain pipe 732 also facilitates the adjustment of the position and orientation of the drain outlet 730, which can be flexibly aligned according to the actual installation posture and water spraying requirements of the water spraying component 6, further improving the accuracy of condensate delivery and adapting to different assembly conditions.

[0119] The drain pipe 732 can be a rubber pipe or other possible tubular structure, and this embodiment does not limit it.

[0120] The drain pipe 732 and the water collection box 731 can be integrally formed, or they can be separate structures. When the drain pipe 732 and the water collection box 731 are separate structures, the drain pipe 732 can be interference-fitted into the water collection box 731 to avoid leakage at the connection between the drain pipe 732 and the water collection box 731.

[0121] Similarly, the water collection box 731 and the water inlet 72 can also be an integral structure or a separate structure, etc., and this embodiment does not limit this.

[0122] In some embodiments, a flow channel may be integrated on the side wall of the outdoor heat exchanger 4, and the flow channel opening forms the aforementioned drain outlet 730.

[0123] In this way, on the one hand, by integrating the flow channel with the heat exchanger sidewall, the assembly process of the independent drain pipe 732 is eliminated, simplifying the overall structure, reducing the number of parts, and lowering the assembly difficulty and manufacturing cost. On the other hand, the integrated flow channel can shorten the condensate transport path, reduce losses and leakage during the condensate transport process, and at the same time, the fixed position of the flow channel can stably guide the condensate to the water pumping component 6, ensuring a continuous and reliable water supply, and also making the internal layout of the equipment more compact and orderly.

[0124] It should be noted that the number of the aforementioned drain outlets 730 can be one or more.

[0125] When there are multiple drain outlets 730, condensate can be supplied to the water spraying component 6 from multiple points simultaneously, increasing the water supply coverage and making the liquid intake of each area of ​​the water spraying component 6 more uniform. At the same time, it can increase the overall liquid supply flow rate, meet the water demand under heavy operating conditions, and ensure the continuous and stable operation of the water spraying operation.

[0126] In some embodiments, see Figure 7 The condensate distribution component 7 is located at the top of the outdoor heat exchanger 4.

[0127] By positioning the condensate distribution assembly 7 at the top of the outdoor heat exchanger 4, this high-level arrangement aligns with the gravity-flow characteristics of condensate, allowing the collected condensate to be smoothly transported downwards to the water pumping unit 6 without additional power assistance, thus simplifying the drive structure. Furthermore, the condensate distribution assembly 7, located at the top of the outdoor heat exchanger 4, does not obstruct the heat exchange surface or hinder airflow, ensuring normal heat exchange by the outdoor heat exchanger 4. Simultaneously, the overall layout is compact, making efficient use of the upper space of the equipment.

[0128] Of course, in other possible implementations, the condensate distribution component 7 can also be located in other positions. For example, the condensate distribution component 7 can also be installed on the housing 1 or the shroud of the outdoor fan 5, as long as the water-catching component 71 is located on the path of the water-spraying component 6 to the condensate. This embodiment does not limit the setting position of the condensate distribution component 7.

[0129] In some embodiments, see Figure 17 and Figure 18 , Figure 17 This is a schematic diagram of another window air conditioner 100 provided in one embodiment of this application, with some parts of the structure omitted. Figure 18 yes Figure 17 A schematic diagram of the condensate distribution assembly 7 is shown. The outdoor heat exchanger 4 has a condensate distribution assembly 7 at its top, forming a water inlet trough 721. The condensate distribution assembly 7 collects the condensate agitated by the water pump 6 into the water inlet trough 721. The water inlet trough 721 extends along a first direction, and its bottom 7211 has multiple through holes 7211a extending to the top of the outdoor heat exchanger 4. The sum of the cross-sectional areas of the through holes 7211a located above the water-rich zone 42 is less than the sum of the cross-sectional areas of the through holes 7211a located above the water-scarce zone 41.

[0130] Since the condensate distribution assembly 7 is located at the top of the outdoor heat exchanger 4, and the water inlet trough 721 extends along the first direction, the bottom 7211 of the water inlet trough 721 has multiple through holes 7211a extending to the top of the outdoor heat exchanger 4. Furthermore, the sum of the cross-sectional areas of the through holes 7211a above the water-rich zone 42 is less than the sum of the cross-sectional areas of the through holes 7211a above the water-scarce zone 41. Therefore, on the one hand, the condensate in the water inlet trough 721 can be sprayed downwards onto the outdoor heat exchanger 4, where the evaporation of water carries away heat, effectively enhancing the heat exchange capacity of the outdoor heat exchanger 4, while simultaneously achieving condensate recycling.

[0131] On the other hand, along the first direction, the outdoor heat exchanger 4 experiences a gradual decrease in humidity and a continuous increase in dryness due to the condensate sprayed by the water jetting component 6. Based on this, by ensuring that the sum of the cross-sectional areas of the through holes 7211a above the water-rich zone 42 is less than the sum of the cross-sectional areas of the through holes 7211a above the water-scarce zone 41, the water-rich zone 42 itself receives more liquid sprayed by the water jetting component 6, resulting in high overall humidity and sufficient water volume. Furthermore, the total cross-sectional area of ​​all the through holes 7211a above this area is smaller, thus reducing the overall liquid output and minimizing the need for additional water replenishment. This effectively prevents overload and overflow in the water-rich zone 42, and prevents localized water accumulation from affecting evaporative cooling efficiency.

[0132] On the other hand, the water-scarce area 41 naturally receives less liquid and has a drier surface. Correspondingly, the total cross-sectional area of ​​the upper through hole 7211a is larger, resulting in a stronger overall liquid discharge capacity and the ability to replenish more liquid to this area. Through the differentiated design of the two total flow areas, the water demand of different areas of the outdoor heat exchanger 4 is precisely matched, gradually reducing the dryness and wetness difference between the areas and making the overall water distribution of the heat exchanger more uniform.

[0133] Meanwhile, this structure can optimize the liquid flow distribution in the water inlet trough 721, so that the liquid is preferentially supplied to the water-deficient area, improve the recycling rate of condensate, ensure that the evaporative heat dissipation effect of each position of the outdoor heat exchanger 4 is more consistent, thereby improving the heat exchange of the outdoor heat exchanger 4. This can improve the problem of uneven condensate distribution on the surface of the outdoor heat exchanger 4, make the condensate coverage on the surface of the outdoor heat exchanger 4 more uniform, strengthen the evaporative heat dissipation capacity of liquid water, and further improve the overall heat exchange performance and cooling effect of the window air conditioner 100.

[0134] In some embodiments, see Figure 17 and Figure 18 The water-rich area 42 and the water-scarce area 41 are arranged sequentially along the first direction. Multiple through holes 7211a are arranged at intervals along the first direction, and the cross-sectional area of ​​the through holes 7211a gradually increases along the first direction.

[0135] By gradually increasing the cross-sectional area of ​​the through-hole 7211a along the first direction, the liquid output per unit pore volume increases synchronously. The through-holes above the front water-rich zone 42 have a smaller diameter, which controls the water supply and prevents water accumulation and siltation in areas with abundant water, thus preventing local water saturation and reduced evaporative heat dissipation efficiency. The through-holes above the rear water-scarce zone 41 have progressively larger diameters, which can gradually increase the liquid supply and specifically compensate for the lack of natural water in this area.

[0136] This gradient aperture structure can precisely distribute liquid according to the dryness and wetness of different areas of the heat exchanger, reducing the humidity difference between the water-rich area 42 and the water-poor area 41, making the overall water distribution of the outdoor heat exchanger 4 more uniform, maintaining the stable evaporative heat dissipation capacity of each area, and ultimately improving the overall heat exchange efficiency. At the same time, it can also smoothly guide the liquid flow in the water tank 721, preventing liquid stagnation and overflow.

[0137] The shape of the through hole 7211a can be circular, square or other possible shapes, and this embodiment does not limit it.

[0138] In some embodiments, see Figure 17 and Figure 18 The condensate distribution assembly 7 includes a water-catching element 71 and a water-guiding element 72. The water-catching element 71 protrudes from the outdoor heat exchanger 4 along the thickness direction of the outdoor heat exchanger 4 towards the side near the water-pumping element 6 and is located on the condensate throwing path of the water-pumping element 6, for capturing the condensate thrown out when the water-pumping element 6 rotates. The water-guiding element 72 is disposed at the top of the outdoor heat exchanger 4, and the water-guiding element 72 encloses to form a water-guiding groove 721. The water-catching element 71 is connected to the water-guiding groove 721, and the water-guiding groove 721 is along a first direction (exemplarily, it can be...). Figure 17 Extending in the negative direction of the X-axis, the bottom 7211 of the water inlet trough 721 is provided with multiple through holes 7211a that extend to the top of the outdoor heat exchanger 4.

[0139] Multiple through holes 7211a along a first direction (exemplarily, can be...) Figure 18 The holes are arranged at intervals along the negative direction of the X-axis, and the cross-sectional area of ​​the through holes 7211a gradually increases along the first direction.

[0140] Since the water inlet 72 is located at the top of the outdoor heat exchanger 4, the water inlet trough 721 receives the recovered condensate transported by the water catcher 71. The through hole 7211a opened at the bottom of the trough 7211 leads directly to the top surface of the outdoor heat exchanger 4. Therefore, on the one hand, the condensate in the water inlet trough 721 can be sprayed downwards to the outdoor heat exchanger 4, and the heat is carried away by the evaporation of water, which effectively enhances the heat exchange capacity of the outdoor heat exchanger 4, and at the same time realizes the recycling of condensate.

[0141] On the other hand, along the first direction, the outdoor heat exchanger 4 experiences a gradual decrease in humidity and a continuous increase in dryness due to the condensate sprayed by the water-spraying component 6. Based on this, the cross-sectional area of ​​the through hole 7211a is gradually increased along this direction, which correspondingly increases the liquid output per hole: the small diameter at the front end matches the relatively humid area, controlling the liquid output and preventing excessive local water flow that could cause water accumulation and splashing. The large diameter at the rear end can output more condensate, specifically replenishing the water consumption of the dry area and compensating for insufficient natural water spray. This structure can balance the overall humidity of the outdoor heat exchanger 4, ensuring consistent evaporative heat dissipation efficiency in each area, thereby improving the outdoor heat exchanger 4. This improves the uneven distribution of condensate on the surface of the outdoor heat exchanger 4, making the condensate coverage more uniform, enhancing the evaporative heat dissipation capacity of liquid water, and further improving the overall heat exchange performance and cooling effect of the window air conditioner 100.

[0142] In some embodiments, the water guide 72 includes a blind section 722 and an orifice section 723, wherein the orifice section 723 is connected to the blind section 722 and the blind section 722 and the orifice section 723 are along a first direction (exemplarily, it can be...). Figure 18 Multiple through holes 7211a are arranged sequentially in the negative direction of the X-axis, and are set at the bottom of the groove 7211 corresponding to the hole section 723.

[0143] Since the perforated section 723 is connected to the blind section 722 and the blind section 722 and the perforated section 723 are arranged sequentially along the first direction, and multiple through holes 7211a are set at the bottom of the tank 7211 corresponding to the perforated section 723, on the one hand, the bottom of the tank 7211 corresponding to the blind section 722 does not have through holes 7211a, so the condensate cannot seep downwards, which can prevent the condensate from splashing onto the water-rich area 42 of the outdoor heat exchanger 4, thus avoiding excessive water in this area and preventing water accumulation and excessive water spraying.

[0144] On the other hand, condensate flows downwards only from the orifice section 723 and sprays onto the water-deficient zone 41. Combined with the gradually changing cross-sectional area of ​​the through-hole 7211a described above, the water supply to the dry water-deficient zone 41 can be targeted, and the water spray volume in each area of ​​the outdoor heat exchanger 4 can be precisely adjusted, reducing the dry-wet difference between the water-rich zone 42 and the water-deficient zone 41, making the overall heat exchange efficiency more balanced. At the same time, the zoned structure simplifies the water distribution layout, makes the condensate flow direction more controllable, and also reduces the ineffective loss of condensate.

[0145] In some embodiments, see Figure 18 Along the first direction (for example, it can be Figure 18 (in the negative direction of the X-axis), the length of the blind section 722 is L1, and the length of the hole section 723 is L2, where L1 < L2.

[0146] By making L1 < L2, on the one hand, the length L1 of the blind zone 722 is smaller, corresponding to a limited coverage area of ​​the water-rich zone 42 of the outdoor heat exchanger 4, which only blocks water in areas with sufficient water and does not occupy too much space in the water inlet trough 721. On the other hand, the length L2 of the perforated zone 723 is larger, allowing for the arrangement of more through holes 7211a, corresponding to the water-scarce zone 41 of the outdoor heat exchanger 4. This expands the water replenishment range, increases the overall water replenishment volume, fully compensates for the water shortage in dry areas, further reduces the dry-wet difference between different areas of the outdoor heat exchanger 4, and ensures a uniform and stable heat exchange state across the entire surface.

[0147] Of course, in other embodiments, L2 may be greater than L1, or L2 may be equal to L1. This embodiment does not limit this.

[0148] In some embodiments, see Figure 18 ,1 / 5<L1 / (L1+L2)<1 / 2.

[0149] If L1 / (L1+L2) > 1 / 2, the length of the blind zone 722 is too large, significantly compressing the effective layout space of the hole section 723. Consequently, the number and coverage of the arable through holes 7211a decrease, failing to adequately cover the water-deficient area 41 of the outdoor heat exchanger 4. The water-deficient area 41 does not receive sufficient and widespread water replenishment, further widening the difference between the dry and wet areas of the heat exchanger, resulting in insufficient local heat dissipation and a decrease in overall heat exchange efficiency. Simultaneously, most of the water inlet trough 721 cannot distribute water downwards, leading to low condensate circulation utilization.

[0150] If L1 / (L1+L2) < 1 / 5, the length of the blind zone 722 is insufficient to completely correspond to the water-rich zone 42 of the outdoor heat exchanger 4, and some of the through holes 7211a will extend above the water-rich zone 42. Excess condensate will continuously drip into the already water-sufficient water-rich zone 42, easily causing local water accumulation and overflow. This not only wastes water resources but also affects the evaporative heat dissipation effect due to local water saturation, thus also disrupting the overall heat exchange uniformity of the outdoor heat exchanger 4.

[0151] Based on this, by ensuring that 1 / 5 < L1 / (L1+L2) < 1 / 2, on the one hand, the blind zone 722 has a moderate length, which can completely avoid the water-rich zone 42 of the outdoor heat exchanger 4, effectively preventing additional condensate from entering and avoiding the problem of excessive water volume and overflow in the water-rich zone 42. On the other hand, the perforated zone 723 occupies most of the length of the water inlet trough 721, providing ample space for the through holes 7211a, which can fully cover the larger water-scarce zone 41, achieving large-scale and sufficient water replenishment. This ratio takes into account both the needs of water isolation and water replenishment, effectively balancing the dry and wet states of each area of ​​the outdoor heat exchanger 4, making the evaporative heat dissipation efficiency of each area more consistent, and ultimately ensuring the overall heat exchange performance of the window air conditioner 100 is stable.

[0152] In some embodiments, see Figure 19 , Figure 19 This is a schematic diagram of another condensate distribution component provided in an embodiment of this application. Along the first direction (exemplarily, it can be...) Figure 19 (In the negative direction of the X-axis), the distance between adjacent through holes 7211a gradually decreases.

[0153] By gradually decreasing the spacing between adjacent through holes 7211a along the first direction, the spacing between adjacent through holes 7211a along the first direction can be gradually reduced, and the number of through holes 7211a per unit length can be continuously increased, resulting in a denser water distribution point. This further increases the overall liquid output in the downstream area, precisely matching the increasing dryness of the outdoor heat exchanger 4 along the first direction. The dense water distribution point allows for more uniform water distribution in the water-scarce area 41, eliminating local water replenishment blind spots, fully enhancing the water spraying and heat dissipation effect in the dry area, and ensuring consistent heat exchange performance at all locations of the outdoor heat exchanger 4, thereby further improving the heat exchange effect of the outdoor heat exchanger 4.
