[0058] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0059] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0060] Hereinafter, with reference to the accompanying drawings, a window air conditioner 100 according to an embodiment of the present invention will be described.

[0061] refer to Figure 1 and Figure 2 The window air conditioner 100 includes a chassis 1, an indoor unit assembly 2, and an outdoor unit assembly 3. The indoor unit assembly 2 is located above the chassis 1, and the outdoor unit assembly 3 is located above the chassis 1. The portion of the chassis 1 located below the outdoor unit assembly 3 is the outer chassis portion 1a, and the portion of the chassis 1 located below the indoor unit assembly 2 is the inner chassis portion 1b. A water-blocking structure 10 is provided on the chassis 1, and the water-blocking structure 10 is located on the edge of the inner chassis portion 1b near the outer chassis portion 1a.

[0062] The edge of the inner chassis portion 1b near the outer chassis portion 1a refers to the edge of the inner chassis portion 1b near the outside. The water-blocking structure 10 can be on the inner chassis portion 1b or on the outside of the inner chassis portion 1b. More specifically, the water-blocking structure 10 can be provided on the inner chassis portion 1b and located on the inner chassis portion 1b near the outer chassis portion 1a. Alternatively, the water-blocking structure 10 can not be provided on the inner chassis portion 1b, but can be provided on the chassis 1 near the inner chassis portion 1b (for example, provided on the middle portion 1c mentioned later and located on the middle portion 1c near the inner chassis portion 1b).

[0063] The specific form of the water-blocking structure 10 is not limited. For example, the water-blocking structure 10 can be a rib, with the portion of the rib adjacent to the inner base portion 1b protruding upwards. Water on the base 1 located between the inner base portion 1b and the outer base portion 1a is difficult to backflow into the inner base portion 1b due to the blocking effect of the rib. Alternatively, the water-blocking structure 10 can be a groove, with the portion of the groove adjacent to the inner base portion 1b recessed downwards. Water on the base 1 located between the inner base portion 1b and the outer base portion 1a, when flowing towards the inner base portion 1b, will first accumulate in the groove and will not backflow into the inner base portion 1b. Or, the water-blocking structure 10 can also include water-absorbing material or a pumping device, etc., in addition to the rib or groove. In short, any structural component that can block water and prevent water from backflowing into the inner base portion 1b is acceptable, which will not be elaborated here.

[0064] Therefore, by setting a water-blocking structure 10 on the chassis 1 and placing the water-blocking structure 10 at the edge of the inner chassis portion 1b near the outer chassis portion 1a, the problem of water on the chassis 1 flowing back into the inner chassis portion 1b through the water-blocking structure 10 is avoided, reducing the risk of water intrusion into the indoor unit component 2. This solves the problems of corrosion and damage to the internal components of the indoor unit component 2 caused by water intrusion, improves the reliability of the window air conditioner 100, solves the problem of bacteria growing in the indoor unit component 2 due to water accumulation caused by water intrusion, and also avoids the problem of water dripping into the room due to water intrusion.

[0065] In some embodiments, reference Figure 2 and Figure 3 The water-blocking structure 10 may include a water-blocking rib 11, the portion of the water-blocking rib 11 adjacent to the inner chassis portion 1b protruding upwards. Thus, the structure of the water-blocking rib 11 is simple, easy to manufacture, and has a more reliable water-blocking effect.

[0066] The water-blocking rib 11 can be a raised structure formed by the chassis 1 itself, or it can be a structure set separately on the chassis 1; the shape of the water-blocking rib 11 is not limited, for example, it can be a straight line, a wave shape, an arc shape, etc.

[0067] The number of water-blocking ribs 11 is not limited. For example, only one water-blocking rib 11 can be set on the chassis 1, or multiple water-blocking ribs 11 can be set. For example, multiple water-blocking ribs 11 can be set sequentially in the direction from the indoor unit component 2 to the outdoor unit component 3 to form multiple protections. Alternatively, multiple water-blocking ribs 11 can be set on the chassis 1 and reasonably arranged according to the possible flow path of water to form a complex water-blocking system, further enhancing the waterproof effect.

[0068] The material of the water-blocking rib 11 is not limited. For example, the water-blocking rib 11 can be made of plastic, which has the advantages of being lightweight, low cost, and easy to process and mold. At the same time, plastic has a certain degree of flexibility, which can buffer the impact of water to a certain extent. For example, the water-blocking rib 11 can be made of metal materials such as aluminum alloy and stainless steel. Metal materials have high strength, good corrosion resistance, long service life, and can withstand greater water pressure and external impact. For example, the water-blocking rib 11 can also be made of rubber. Rubber has good elasticity and sealing properties, which can fit tightly against the surface of the chassis 1 and effectively prevent water penetration.

[0069] The method of handling water blocked by the water-blocking rib 11 is not limited. For example, the blocked water can be disposed of through various methods such as natural evaporation, water absorption components, or drainage components. For example, if the window air conditioner 100 is installed in an environment with low humidity and good ventilation, it can use natural evaporation. The water evaporates naturally in the outdoor air without interfering with the normal operation of the air conditioner, and also reduces energy consumption. For example, if the window air conditioner 100 is installed in an environment with low humidity and high temperature, it can use water absorption components. The water absorption components can quickly absorb the accumulated water, and the water absorption components can be replaced periodically or dried and reused, resulting in low cost. For example, if the window air conditioner 100 is installed in an environment with high rainfall or a lot of water accumulation, it can use drainage facilities. The drainage facilities can include structures such as drain holes and drain channels. Through reasonable design and layout, the accumulated water is guided to a suitable drainage location, ensuring that the inside of the air conditioner remains dry and improving the reliability of the air conditioner.

[0070] In some embodiments, reference Figure 2 and Figure 3 A first water trough 13 is formed on the chassis 1, and a water baffle 11 intercepts the side of the first water trough 13 near the inner chassis portion 1b (i.e., intercepts the side of the first water trough 13 near the indoor side). The window air conditioner 100 has a first drainage path 100b that communicates with the first water trough 13.

[0071] Therefore, by setting up the first water tank 13, the disorderly accumulation of intercepted water in other areas of the chassis 1 is reduced, allowing for centralized collection of the water. This, combined with the first drainage path 100b, enables directional discharge of the water. For example, the water can be drained from the chassis 1; or, for example, the water can be guided to the area below the outdoor fan of the outdoor unit assembly 3, where the fan impeller can agitate the water and splash it onto the surface of the outdoor heat exchanger of the outdoor unit assembly 3 to aid heat dissipation and improve cooling capacity; or, for example, the water can be atomized and sprayed outdoors using nozzles, and so on.

[0072] In the embodiments of this application, the first water tank 13 can be a groove formed by the chassis 1 itself, or it can be a water tank structure set separately on the chassis 1. The shape of the first water tank 13 is not limited, and it can be adapted according to the shape of the water-blocking rib 11, the structural space of the chassis 1, etc. For example, the water-blocking rib 11 can be constructed to surround one side of the first water tank 13. The shape of the first water tank 13 is not limited, and it can be a regular shape or an irregular shape, etc.

[0073] For example, refer to Figure 3 The first drainage path 100b includes a first drainage hole 14, which is located on the outdoor side portion of the chassis 1. Thus, water intercepted by the baffle 11 and entering the first water tank 13 can be discharged to the outdoor side through the first drainage hole 14. The first drainage path 100b is short and direct, reducing the residence time and flow obstruction of water inside the air conditioner, improving drainage efficiency, reducing the risk of water accumulating in the first water tank 13 and flowing back into the indoor unit assembly 2, and lowering the possibility of damage to the indoor unit assembly 2 due to water accumulation.

[0074] In the embodiments of this application, the shape of the first drain hole 14 is not limited. For example, the shape of the first drain hole 14 can be circular, elliptical, square, etc.; the number of the first drain holes 14 is not limited, for example, the number of the first drain holes 14 can be 1, 2, 3, 4, etc. For example, multiple first drain holes 14 can be arranged in zones according to the water accumulation in different areas of the first water tank 13. More first drain holes 14 are arranged in areas with larger drainage volume, and fewer first drain holes 14 are arranged in areas with smaller drainage volume.

[0075] In some embodiments, reference Figures 1-2 The indoor unit assembly 2 and the outdoor unit assembly 3 are spaced apart to form a receiving space 100a above the chassis 1, located between the indoor unit assembly 2 and the outdoor unit assembly 3. The receiving space 100a refers to the specific space formed by the spaced indoor unit assembly 2 and the outdoor unit assembly 3 above the chassis 1, which is used to accommodate components such as the window sash 200 to meet the installation and use requirements of the window air conditioner 100.

[0076] Combination Figures 4-6 The accommodating space 100a accommodates a window sash 200, which is located between the indoor unit assembly 2 and the outdoor unit assembly 3. The side of the window sash 200 closer to the outdoor unit assembly 3 is the outer side of the window sash, and the side of the window sash 200 closer to the indoor unit assembly 2 is the inner side of the window sash. The water-blocking rib 11 is located on the inner side of the window sash, and the water flowing down the window sash 200 can also be blocked by the water-blocking rib 11, which has a good water-blocking effect.

[0077] For example, refer to Figure 1 and Figure 2The indoor unit assembly 2 and the outdoor unit assembly 3 are spaced apart along the first direction F1. The accommodating space 100a is open along the second direction F2 and has an open top. The first direction F1 and the second direction F2 are perpendicular to the vertical direction. For example, the first direction F1 is the front-to-back direction and the second direction F2 is the left-to-right direction. The left and right sides and the top of the accommodating space 100a are open, so the window sash 200 can enter the accommodating space 100a downwards. Of course, this application is not limited to this. For example, in other examples, the indoor unit assembly 2 and the outdoor unit assembly 3 are spaced apart along the first direction F1. The accommodating space 100a can be open at one end and the top along the second direction F2. For example, the first direction F1 is the front-to-back direction and the second direction F2 is the left-to-right direction. The left side and the top of the accommodating space 100a are open, so the window sash 200 can enter the accommodating space 100a from left to right. Similarly, the accommodating space 100a can also be open on the right side and at the top, so the window sash 200 can enter the accommodating space 100a from right to left.

[0078] In some embodiments, reference Figure 2 The surface of the indoor unit assembly 2 facing the receiving space 100a is the outer wall surface 20 of the indoor unit, and the water-retaining rib 11 is located on the side of the outer wall surface 20 away from the outer chassis portion 1a. That is, the water-retaining rib 11 is located on the side closer to the interior of the vertical plane on which the outer wall surface 20 of the indoor unit is located.

[0079] Therefore, the water-blocking rib 11 is set within the downward projection range of the indoor unit component 2, and the indoor unit component 2 is located on the indoor side. In this way, the water flowing down the outside of the window sash 200 can be blocked by the water-blocking rib 11, and the side of the water-blocking rib 11 near the outdoor unit component 3 has a certain space to accommodate more rainwater, thereby increasing the water-holding capacity of the chassis 1. This allows the chassis 1 to accumulate more water without backflowing into the indoor unit component 2 and thus invading the room.

[0080] In some embodiments, reference Figure 2 The surface of the indoor unit assembly 2 facing the accommodating space 100a is the outer wall surface 20 of the indoor unit. The first drain hole 14 is located on the side of the outer wall surface 20 of the indoor unit closer to the outdoor unit assembly 3 (i.e., the first drain hole 14 is located on the side of the outer wall surface 20 of the indoor unit closer to the outside), and the distance L between the first drain hole 14 and the outer wall surface 20 of the indoor unit is greater than 5 mm. For example, the distance L between the first drain hole 14 and the outer wall surface 20 of the indoor unit can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, etc. Here, the distance L between the first drain hole 14 and the outer wall surface 20 of the indoor unit refers to the distance in the spacing direction between the indoor unit assembly 2 and the outdoor unit assembly 3 (for example, the first direction F1 shown in the figure).

[0081] In the above technical solution, the first drain hole 14 is located on the side of the inner unit outer wall 20 close to the outer unit component 3, and the distance L between the first drain hole 14 and the inner unit outer wall 20 is greater than 5mm, so as to better ensure that the first drain hole 14 can be located on the outdoor side.

[0082] For example, the indoor unit assembly 2 may include an inner frame 21, and the outer wall surface 20 of the indoor unit may be the side surface of the inner frame 21 facing the receiving space 100a. Alternatively, the side of the inner frame 21 facing the receiving space 100a may also be open, and the indoor heat exchanger 22 in the indoor unit assembly 2 may be disposed facing the receiving space 100a, in which case the side surface of the indoor heat exchanger 22 facing the receiving space 100a serves as the outer wall surface 20 of the indoor unit.

[0083] In some embodiments, reference Figure 2 The surface of the outdoor unit assembly 3 facing the accommodating space 100a is the inner wall surface 30 of the outdoor unit. The first drain hole 14 is located between the outer wall surface 20 of the indoor unit and the inner wall surface 30 of the outdoor unit, and is positioned closer to the inner wall surface 30 than the outer wall surface 20. That is, along the spacing direction between the indoor unit assembly 2 and the outdoor unit assembly 3 (e.g., the first direction F1 shown in the figure), the first drain hole 14 is located between the vertical plane containing the outer wall surface 20 of the indoor unit and the vertical plane containing the inner wall surface 30 of the outdoor unit. The distance between the first drain hole 14 and the vertical plane containing the outer wall surface 20 of the indoor unit is greater than the distance between the first drain hole 14 and the vertical plane containing the inner wall surface 30 of the outdoor unit.

[0084] In the above technical solution, since the first drain hole 14 is located between the outer wall surface 20 of the indoor unit and the inner wall surface 30 of the outdoor unit, and is set closer to the inner wall surface 30 of the outdoor unit than the outer wall surface 20 of the indoor unit, the first drain hole 14 can be located more reliably on the outdoor side, and the first drain path 100b is more direct and smooth.

[0085] For example, the outdoor unit assembly 3 may include an outer frame 31, and the inner wall surface 30 of the outdoor unit may be the side surface of the outer frame 31 facing the receiving space 100a. Alternatively, the side of the outer frame 31 facing the receiving space 100a may also be open, and the outdoor heat exchanger 32 in the outdoor unit assembly 3 may be disposed facing the receiving space 100a, in which case the side surface of the outdoor heat exchanger 32 facing the receiving space 100a serves as the inner wall surface 30 of the outdoor unit.

[0086] For example, the window sash 200 is located in the middle of the accommodating space 100a, that is, in the middle of the outer wall surface 20 of the indoor unit and the inner wall surface 30 of the outdoor unit. The first drain hole 14 is located relative to the outer wall surface 20 of the indoor unit and close to the inner wall surface 30 of the outdoor unit, so that the lower part of the first drain hole 14 corresponds to the windowsill or cantilevered out of the wall 300, thereby allowing water to be discharged from the first drain hole 14 and dissipated into the outdoor environment more quickly, reducing the impact of water on the indoor unit components 2.

[0087] Alternatively, in some other embodiments, the first drain hole 14 may also be located on the side of the inner wall surface 30 of the outdoor unit away from the indoor unit assembly 2 (this example is not shown in the figure), that is, the first drain hole 14 is located on the side of the vertical plane where the inner wall surface 30 of the outdoor unit is located, closer to the outside. This allows the first drain hole 14 to be closer to the outdoor environment and farther from the indoor unit assembly 2, thus providing sufficient space to install the first water tank 13 below the accommodating space 100a, increasing the capacity of the first water tank 13, thereby coping with situations where a large amount of water accumulates in a short time. Combined with the water-blocking rib 11, this more effectively prevents water from flowing back into the interior of the indoor unit assembly 2.

[0088] In some embodiments, reference Figure 3 The first water tank 13 includes a water collection tank 131 and a drainage tank 132. The water collection tank 131 extends along the extension direction of the water-blocking rib 11, and the drainage tank 132 extends from the water collection tank 131 toward a direction away from the water-blocking rib 11. The first drainage hole 14 penetrates the bottom surface of the drainage tank 132.

[0089] Wherein, the water collection groove 131 extends along the extension direction of the water-blocking rib 11, which means that the water collection groove 131 and the water-blocking rib 11 extend in the same direction. If the water-blocking rib 11 is formed as a straight rib extending along a straight line, then the water collection groove 131 is formed as a straight groove parallel to it. If the water-blocking rib 11 is formed as a curved rib extending along a curve, then the water collection groove 131 is formed as a curved groove that follows its shape.

[0090] In the above technical solution, the water collection trough 131 is arranged adjacent to the water-blocking rib 11 and extends along the extension direction of the water-blocking rib 11, so as to quickly collect the water flowing down intercepted by the water-blocking rib 11. The drainage trough 132 extends from the water collection trough 131 in a direction away from the water-blocking rib 11, so that the first drainage hole 14 penetrating the bottom surface of the drainage trough 132 can be closer to the outdoor side, thereby guiding the water flow to the outdoor environment and effectively reducing the possibility of water crossing the water-blocking rib 11 and entering the room, ensuring the normal operation of the drainage system.

[0091] Furthermore, the combination of the water collection trough 131 and the drainage trough 132 eliminates the need for an excessively large overall area for the first water trough 13, thus allowing space in the chassis 1 for the installation of other structural components. In addition, the combination of the water collection trough 131 and the drainage trough 132 forms a water-retaining space with a buffering effect. In the event of a large amount of water accumulation in a short period, both the water collection trough 131 and the drainage trough 132 can accommodate water exceeding the drainage capacity for a short time, providing a buffer time for water discharge and reducing the risk of water accumulating and overflowing the water-retaining rib 11 to enter the room, ensuring the normal operation of the drainage system.

[0092] In some embodiments, reference Figure 2 and Figure 3The portion of chassis 1 located below the accommodating space 100a is a middle portion 1c, which connects the inner chassis portion 1b and the outer chassis portion 1a. The first water tank 13 includes a water accumulation trough 131 formed by a partial recess in the middle portion 1c, and the water accumulation trough 131 extends along the extending direction of the water-blocking rib 11. In this embodiment, the first water tank 13 may or may not include a drainage trough 132, and the first drainage path 100b may be a first drainage hole 14, but is not limited to a first drainage hole 14; that is, drainage of the water accumulation trough 131 can be achieved in other ways.

[0093] Therefore, since the water collection trough 131 extends along the extension direction of the water-blocking rib 11 and is formed by a partial depression in the middle part 1c, the space occupied by the water collection trough 131 on the chassis 1 is reduced while ensuring that the first water trough 13 can quickly collect the water intercepted by the water-blocking rib 11. For example, the water collection trough 131 will not occupy the space of the outer chassis part 1a, so that the outer chassis part 1a can have more space to complete other functions. For example, the chassis 1 can save space to set up the platform part 17, thereby meeting the support requirements of the base 41.

[0094] In some embodiments, reference Figures 1-3 The first water tank 13 also includes a drain trough 132. The surface of the outdoor unit assembly 3 facing the receiving space 100a is the inner wall surface 30 of the outdoor unit. The drain trough 132 extends from the water collection tank 131 toward the side of the inner wall surface 30 of the outdoor unit away from the indoor unit assembly 2 (i.e., extends to the side of the vertical plane where the inner wall surface 30 of the outdoor unit is located, closer to the outside). The first drainage path 100b includes a first drainage hole 14, which penetrates the bottom surface of the end of the drain trough 132 away from the water collection tank 131.

[0095] Therefore, the first drain hole 14 can be far away from the indoor unit component 2 and closer to the outdoor environment. The water in the water accumulation tank 131 will first enter the drain tank 132, and then flow to the first drain hole 14 near the outdoor side through the guide of the drain tank 132, and be discharged to the outside through the first drain hole 14. Even if the drainage is not timely, the drain tank 132 can temporarily accommodate the excess water, reducing the risk of water accumulation crossing the water baffle 11 and entering the room, and improving the waterproof reliability of the window air conditioner 100.

[0096] In some embodiments, reference Figure 2 and Figure 3The two ends of the water-retaining rib 11 extend to the two side edges of the chassis 1 in the second direction F2. The indoor unit assembly 2 and the outdoor unit assembly 3 are arranged along the first direction F1, which is perpendicular to the second direction F2. Both the first direction F1 and the second direction F2 are perpendicular to the vertical direction. For example, the first direction F1 is the front-to-back direction, and the second direction F2 is the left-to-right direction. The left end of the water-retaining rib 11 extends to the left side edge of the chassis 1, and the right end of the water-retaining rib 11 extends to the right side edge of the chassis 1.

[0097] At this time, the water-blocking rib 11 divides the chassis 1 into two areas in the first direction F1. The two areas are blocked by the water-blocking rib 11. Thus, no matter where the water enters, it can be effectively intercepted by the water-blocking rib 11. The water cannot cross the water-blocking rib 11 and enter the area where the indoor unit component 2 is located, thereby reducing the risk of water entering the room.

[0098] Of course, this application is not limited to this. For example, in other embodiments of this application, if the chassis 1 itself has other structural components that can block water, the water-blocking rib 11 can block water together with these structural components, so that the two ends of the water-blocking rib 11 do not need to extend to the two sides of the chassis 1 in the second direction F2 respectively.

[0099] The shape of the water-blocking rib 11 is not limited. For example, the water-blocking rib 11 can be constructed as a straight rib extending along the second direction F2, wherein the indoor unit assembly 2 and the outdoor unit assembly 3 are arranged along the first direction F1, the first direction F1 is perpendicular to the second direction F2, and both the first direction F1 and the second direction F2 are perpendicular to the vertical direction. This type of water-blocking rib 11 has a simple structure, is easy to manufacture and install, and occupies little space, which is beneficial to leave more space for the inner chassis 1b to set other structures (such as the first air inlet 12). The straight water-blocking rib 11 can be formed by stamping the chassis 1, or the straight water-blocking rib 11 can also be a separate component installed on the chassis 1. The straight water-blocking rib 11 has a regular shape, and can be quickly and accurately installed on the chassis 1 during the installation process, which is simple and improves production efficiency. Alternatively, for example, the water-blocking rib 11 can also be curved (such as wavy) or sawtooth, etc. Wavy or sawtooth water-blocking ribs 11 increase the contact area with water, which can better disperse the water flow, reduce the impact force of water, and enhance the ability to intercept water flow.

[0100] In some embodiments, the two ends of the water-retaining rib 11 extend to the two side edges of the chassis 1 in the second direction F2, respectively. The water-retaining rib 11 can be constructed as a straight rib extending along the second direction F2. The indoor unit assembly 2 and the outdoor unit assembly 3 are arranged along the first direction F1, which is perpendicular to the second direction F2. Both the first direction F1 and the second direction F2 are perpendicular to the vertical direction. This simplifies the structure of the chassis 1 and the water-retaining rib 11, and facilitates the processing of the chassis 1 and the water-retaining rib 11.

[0101] In some embodiments, reference Figure 2 and Figure 3 A first air inlet 12 is formed on the inner chassis portion 1b, and the first air inlet 12 is located on the side of the water-retaining rib 11 away from the outer chassis portion 1a. That is, the first air inlet 12 is located on the side of the water-retaining rib 11 closer to the indoor side. Thus, the chassis 1 forms the first air inlet 12 on the side of the water-retaining rib 11 away from the outdoor unit assembly 3, that is, the water-retaining rib 11 is set on the side of the first air inlet 12 closer to the outdoor unit assembly 3. Therefore, the water-retaining rib 11 can prevent water from flowing back into the side of the first air inlet 12, and thus can prevent water from dripping through the first air inlet 12 and entering the room.

[0102] Furthermore, by placing the first air inlet 12 on the chassis 1, the number of air inlets on other exterior surfaces of the indoor unit assembly 2 can be reduced or eliminated, simplifying the appearance structure of the indoor unit assembly 2. In addition, the airflow directly enters the window air conditioner 100 from the first air inlet 12 on the chassis 1, reducing the possibility of airflow crossing between the air inlet and the air outlet, reducing the possibility of airflow short-circuiting back from the air outlet to the air inlet, and improving heat exchange efficiency.

[0103] Furthermore, when the water-blocking rib 11 is constructed as a straight rib extending along the second direction F2, and the chassis 1 forms a first air inlet 12 on the side of the water-blocking rib 11 away from the outdoor unit component 3, the straight water-blocking rib 11 will not occupy too much space on the chassis 1 where the first air inlet 12 is located, thereby leaving more space to set the first air inlet 12, thereby improving the ventilation effect.

[0104] For example, refer to Figure 2 , Figures 7-9 The indoor unit assembly 2 includes an indoor heat exchanger 22 and an indoor fan 23. The indoor heat exchanger 22 includes a first heat exchange section 221 located below the indoor fan 23. The first heat exchange section 221 is located above the first air inlet 12. The window air conditioner 100 also includes a drain structure 4, which includes a water collection tray 42 located between the chassis 1 and the first heat exchange section 221. The water collection tray 42 defines a water trough 421. Thus, the water trough 421 can collect the condensate dripping from the indoor heat exchanger 22 during cooling mode, preventing the condensate from falling into the first air inlet 12 and solving the problem of water dripping from the first air inlet 12.

[0105] For example, refer to Figure 2 , Figures 7-9The outer chassis 1a has a second water tank 15 and a second drain hole 16. The water receiving tank 421 is connected to the second water tank 15 through a second drain path 100c, and the second drain hole 16 is also connected to the second water tank 15. Thus, water collected in the water receiving tank 421 can be drained into the second water tank 15 through the second drain path 100c, and then discharged from the second drain hole 16. The configuration of the second drain path 100c is not limited; for example, it can be a water pump, a drain pipe, or a water tank, as long as it can drain water from the water receiving tank 421 into the second water tank 15.

[0106] For example, refer to Figures 7-9 The second drainage path 100c includes a drainage trough 413 defined by the drainage structure 4, which connects the water receiving trough 421 and the second water tank 15. In this way, the water receiving trough 421 collects condensate from the indoor heat exchanger 22 and directs it to the drainage trough 413. The outlet of the drainage trough 413 is connected to the second drain hole 16 via the second water tank 15. Thus, through the water receiving trough 421, the drainage trough 413, the second water tank 15, and the second drain hole 16, condensate can be discharged from the indoor unit assembly 2 in a timely and smooth manner, reducing water accumulation in the indoor unit assembly 2 and minimizing problems such as bacterial and mold growth caused by water accumulation, thereby keeping the air blown out by the window air conditioner 100 clean and hygienic.

[0107] Combination Figures 10-12 The water receiving trough 421, the drainage trough 413, the second water trough 15, etc. can all be set with a certain downward slope in the drainage direction, so as to realize the orderly discharge of water by gravity. No additional power equipment is required, and the structure is simple and reliable.

[0108] For example, a temperature-controlled drain valve can be installed on the second drain hole 16 to regulate drainage and water storage. In cooling mode, the second drain hole 16 can be closed to store water. The second water tank 15 can be connected to the bottom of the outdoor fan of the outdoor unit assembly 3. The impeller of the outdoor fan pumps water and splashes it onto the surface of the outdoor heat exchanger of the outdoor unit assembly 3 to assist in heat dissipation and improve the cooling capacity of the window air conditioner 100.

[0109] In some embodiments, the drain structure 4 is a single-piece molded component (this example is not shown in the figure). In this case, both the drain trough 413 and the water collection trough 421 are defined by the drain structure 4. Therefore, the drain structure 4 has a complete overall structure without any seams or gaps. This allows the condensate generated by the indoor heat exchanger 22 to be smoothly collected into the water collection trough 421, reducing the possibility of condensate leakage into other components inside the air conditioner due to loose joints. During drainage, the single-piece structure also enhances the continuity of drainage, allowing condensate to flow more smoothly from the water collection trough 421 and drain trough 413 through the second water tank 15 to the second drain hole 16 and then out, further improving drainage efficiency.

[0110] Alternatively, in some other embodiments, refer to Figures 7-9 The drainage structure 4 also includes a base 41, which is located above the chassis 1 and defines a drainage groove 413. A water receiving tray 42 is located above the base 41. A vent 411 is formed on the base 41. A first air inlet 12 is connected to the vent 411. The coverage of the vent 411 exceeds the orthographic projection range of the water receiving tray 42 on the base 41.

[0111] In the above technical solution, a vent 411 is provided on the base 41 and is connected to the first air inlet 12 on the chassis 1. Simultaneously, the coverage area of ​​the vent 411 exceeds the orthogonal projection range of the water collection tray 42 on the base 41. This ensures that although the water collection tray 42 occupies some space in the air intake path, it does not significantly obstruct the airflow through the vent 411. Indoor air can bypass the water collection tray 42 and pass through other areas of the vent 411, ensuring smooth air circulation. Therefore, the window air conditioner 100 can accommodate both condensate collection and air intake functions of the chassis 1. The window air conditioner 100 can effectively collect condensate while simultaneously increasing the air intake area using the first air inlet 12 on the chassis 1.

[0112] Furthermore, in order to increase the air-receiving area, the first heat exchange section 221 can be configured as an upward-opening V-shaped or C-shaped structure, that is, the lower end of the first heat exchange section 221 extends toward the water receiving tray 42, and the upper end of the first heat exchange section 221 extends away from the water receiving tray 42. Water flowing down along the first heat exchange section 221 can enter the water receiving tray 42. The projection of the first heat exchange section 221 onto the horizontal plane exceeds the water receiving tray 42, and the size of the water receiving tray 42 can be reduced, thereby increasing the air-receiving area of ​​the first heat exchange section 221.

[0113] The drainage structure 4 adopts a split design of base 41 and water tray 42, which makes reasonable use of space while fulfilling the drainage function. The base 41 is set above the chassis 1, providing stable support for the water tray 42, and by setting a vent 411, air circulation is achieved without affecting the drainage function. This makes the internal structure of the air conditioner more compact, the space allocation between the components more reasonable, and improves the space utilization rate.

[0114] Furthermore, the indoor unit assembly 2 can also have air inlets located in other positions. For example, the indoor unit assembly 2 and the outdoor unit assembly 3 are spaced apart to form a receiving space 100a above the chassis 1 between the indoor unit assembly 2 and the outdoor unit assembly 3. (See reference...) Figure 2The indoor unit assembly 2 includes an indoor heat exchanger 22 and an indoor fan 23. The indoor heat exchanger 22 includes a second heat exchange section 222 located on the side of the indoor fan 23 near the receiving space 100a. That is, the second heat exchange section 222 is located on the side of the indoor fan 23 near the outdoor side. The indoor unit assembly 2 is provided with a second air inlet 18 on the side of the indoor heat exchanger 22 near the receiving space 100a.

[0115] Therefore, by using the location of the accommodating space 100a, air can be drawn in from the second air inlet 18, which can reduce or eliminate the need to set air inlets on other exterior surfaces of the indoor unit component 2, simplifying the appearance structure of the indoor unit component 2; in addition, the airflow directly enters the window air conditioner 100 from the second air inlet 18 of the chassis 1, reducing the possibility of airflow crossing between the air inlet and the air outlet, reducing the possibility of airflow short-circuiting back from the air outlet to the air inlet, and improving heat exchange efficiency.

[0116] For example, the air outlet 19 of the indoor unit component 2 can be located on the side of the indoor unit component 2 away from the outdoor unit component 3. For example, the side of the indoor unit component 2 away from the outdoor unit component 3 is the front side, and the air outlet 19 can be located at the upper front end of the indoor unit component 2 or at the top front end of the indoor unit component 2. In this way, whether the first air inlet 12 or the second air inlet 18 is used, the possibility of airflow short-circuiting back from the air outlet 19 to the air inlet can be effectively reduced, thereby improving the heat exchange efficiency.

[0117] It is worth noting that the air inlet of the indoor unit component 2 may include only the first air inlet 12, or only the second air inlet 18, or both the first air inlet 12 and the second air inlet 18.

[0118] In some embodiments, reference Figure 3 , Figures 7-9 The water-blocking structure 10 includes a water-blocking rib 11. The portion of the water-blocking rib 11 adjacent to the inner chassis portion 1b protrudes upward. A first water trough 13 is formed on the chassis 1. The water-blocking rib 11 intercepts the side of the first water trough 13 near the inner chassis portion 1b. A first drain hole 14 penetrating the first water trough 13 is formed on the chassis 1. A second water trough 15 is located on the side of the first water trough 13 away from the inner chassis portion 1b.

[0119] This creates two drainage channels: the water receiving trough 421, the drainage trough 413, the second water trough 15, and the second drainage hole 16 form the first drainage channel (for example, to drain condensate from the indoor side), and the first water trough 13 and the first drainage hole 14 form the second drainage channel (for example, to drain rainwater). The second water trough 15 is located on the side of the first water trough 13 away from the inner chassis portion 1b, making the drainage path of the second drainage channel shorter. Rainwater can be discharged from the first drainage hole 14 more quickly, improving drainage efficiency. Combined with the water-blocking rib 11, it reduces the risk of water accumulating in the chassis 1 and backflowing into the room.

[0120] For example, the second water tank 15 and the first water tank 13 are spaced apart and not connected to each other. This forms two independent drainage channels that are not connected to each other. Therefore, the separation of the second water tank 15 and the first water tank 13 prevents backflow of water between the two tanks. For instance, if the second water tank 15 has poor drainage or the water level is too high, because the two tanks are not connected, the water in the first water tank 13 will not be affected by the second water tank 15 and will not overflow the water-blocking rib 11 and flow into the room.

[0121] Furthermore, the drainage system can be divided into zones. The first water tank 13 is mainly responsible for collecting water entering from the receiving space 100a, while the second water tank 15 can be dedicated to collecting condensate drainage. This allows water from different sources to be treated separately, avoiding potential problems caused by water mixing between different areas. For example, if the water quality in different areas is different (e.g., containing different impurities), zoned collection can prevent impurities from clogging the drain holes or affecting drainage efficiency, thereby improving the reliability of the entire drainage system. As another example, the second water tank 15 can collect condensate with relatively low impurity content. The second water tank 15 can be connected to the area below the outdoor fan of the outdoor unit assembly 3, using the fan impeller to pump water and splash it onto the surface of the outdoor heat exchanger of the outdoor unit assembly 3 to assist in heat dissipation and improve the cooling capacity of the window air conditioner 100.

[0122] Alternatively, by way of example, the first water tank 13 and the second water tank 15 are connected or are different parts of the same water tank, with the second water tank 15 being lower than the first water tank 13, and the second drain hole 16 being lower than the first drain hole 14. This improves the reliability of drainage from the first water tank 13. For example, if a large amount of water enters the containing space 100a in a short period (e.g., during a short-term heavy rainfall), the rainwater accumulated in the first water tank 13 can flow to the second water tank 15 for discharge, thereby improving drainage reliability. Furthermore, because the first water tank 13 is higher than the second water tank 15, and the first drain hole 14 is higher than the second drain hole 16, the risk of backflow from the second water tank 15 to the first water tank 13, causing water to overflow the baffle 11 and flow into the room, is reduced.

[0123] In some embodiments, reference Figure 2 , Figure 6 and Figure 7 The indoor unit assembly 2 and the outdoor unit assembly 3 are spaced apart to form a receiving space 100a between the indoor unit assembly 2 and the outdoor unit assembly 3 above the chassis 1. A removable partition 5 is provided between the indoor unit assembly 2 and the outdoor unit assembly 3. The partition 5 is located above the chassis 1 and defines the bottom surface of the receiving space 100a. A first water tank 13 is formed on the chassis 1. At least a portion of the first water tank 13 is located below the partition 5. The water-blocking structure 10 includes a water-blocking rib 11. The water-blocking rib 11 protrudes upward relative to the portion of the inner chassis portion 1b adjacent to the water-blocking rib 11. The water-blocking rib 11 intercepts the side of the first water tank 13 near the inner chassis portion 1b.

[0124] Because a removable partition 5 is provided between the indoor unit assembly 2 and the outdoor unit assembly 3, it indicates that the partition 5 is separable from the chassis 1, the indoor unit assembly 2, and the outdoor unit assembly 3. This facilitates the assembly and maintenance of the entire unit; for example, pipes and cables can be routed below the partition 5. The accommodating space 100a is limited to the top surface of the partition 5 and accommodates the window sash 200. The partition 5 can withstand the weight of the window sash 200 and provides protection for the electrical wiring, refrigerant pipes, and other pipelines below the partition 5. In daily use, the window sash 200 may be subjected to external forces for various reasons, such as wind or human impact. Without the support and protection of the partition 5, these external forces may directly act on the electrical wiring and refrigerant pipes, causing damage. For example, damaged electrical wiring may cause short circuits, leakage, and other safety hazards, threatening the life and property safety of users; a ruptured refrigerant pipe will lead to refrigerant leakage, affecting the cooling effect of the air conditioner, and refrigerant leakage may also cause environmental pollution. The presence of partition 5 can effectively disperse the gravity and external impact of the window sash 200, preventing these key components from being directly damaged and improving the safety and reliability of air conditioning use.

[0125] Furthermore, since the partition 5 is assembled in its current position, there are bound to be assembly gaps, etc. Therefore, by forming a first water trough 13 on the chassis 1, with at least a portion of the first water trough 13 located below the partition 5, rainwater and the like that seeping from the edge of the partition 5 into the chassis 1 can enter the first water trough 13 and be blocked by the water-blocking rib 11, thus preventing backflow into the inner chassis part 1b side.

[0126] For example, refer to Figure 6 and Figure 7The outer casing of the outdoor unit assembly 3 is an outer frame 31. The bottom of the surface of the outer frame 31 facing the receiving space 100a has a downward-curved edge 311, which overlaps with the partition 5. This good overlap provides a certain degree of sealing and waterproofing, preventing rainwater and other liquids from seeping into the chassis 1 from the receiving space 100a. Furthermore, it increases the connection area and strength between the outdoor unit assembly 3 and the partition 5. This overlapping structure can withstand the vibrations and external forces generated during the operation of the air conditioner, preventing loosening or separation between the outdoor unit assembly 3 and the partition 5, thus ensuring the stability of the entire air conditioner structure.

[0127] For example, refer to Figure 6 and Figure 7 The partition 5 includes an overlap portion 51, and a lower flange 311 overlaps the overlap portion 51. The overlap portion 51 is formed as a groove for accommodating the lower flange 311.

[0128] In the above technical solution, the overlapping portion 51 is formed as a groove for accommodating the lower flange 311, thereby increasing the contact area between the lower flange 311 and the overlapping portion 51 of the partition 5, and improving the stability of the overlapping fit. Compared with a planar overlapping, the groove structure can constrain the lower flange 311 from multiple directions, making the connection between the outer frame 31 of the outdoor unit assembly 3 and the partition 5 more stable. During the operation of the window air conditioner 100, components such as the compressor of the outdoor unit assembly 3 will vibrate. The stable overlapping structure can effectively reduce the relative displacement between the outer frame 31 and the partition 5 caused by vibration, and prevent the connection from becoming loose.

[0129] For example, refer to Figure 6 and Figure 7 The partition 5 includes an overlapping portion 51, with a lower flange 311 overlapping the overlapping portion 51. A first through-hole 52 is formed on the overlapping portion 51, and a water-blocking rib 11 is located below the first through-hole 52 on the side near the inner chassis portion 1b. That is, the water-blocking rib 11 is located below the first through-hole 52 on the side near the interior.

[0130] In the above technical solution, a through-hole 52 is formed on the overlapping part 51. When water enters the overlapping area between the outer frame 31 and the partition 5, the first drainage hole 52 provides a channel for water to drain. Without the drainage hole, water may accumulate at the overlapping area, and long-term immersion may cause the partition 5 and the outer frame 31 to rust and corrode, affecting the structural strength and sealing performance. The first drainage hole 52 can promptly drain the accumulated water into the first water tank 13, keeping the overlapping area between the outer frame 31 and the partition 5 dry. Furthermore, water entering the first water tank 13 can be blocked by the water-blocking rib 11, preventing backflow into the inner chassis part 1b.

[0131] For example, refer to Figures 6-9The window air conditioner 100 also includes a base 41, which is located above the chassis 1. The base 41 includes a wire passage 412 located below the partition 5. The wire passage 412 defines a wiring groove 4122. A second drain hole 4121 is formed at the bottom of the wire passage 4122. The second drain hole 4121 communicates with the wiring groove 4122. The water baffle 11 is located on the side below the second drain hole 4121 near the inner chassis 1b.

[0132] In the above technical solution, the base 41 is positioned above the chassis 1, and the wiring portion 412 of the base 41 defines a wiring trough 4122. The wiring trough 4122 provides a dedicated wiring channel for the electrical wires, refrigerant pipes, etc. of the window air conditioner 100. The wires are arranged in an orderly manner within the wiring trough 4122, reducing the mess and mutual interference of the wires, lowering the risk of short circuits, and improving the safety and stability of the electrical system. When water (such as accidental water ingress, rainwater, etc.) enters the wiring trough 4122, the second drainage hole 4121 formed at the bottom of the wiring section 412 is connected to the wiring trough 4122. The water-blocking rib 11 is located below the second drainage hole 4121 on the side close to the indoor unit component 2, so that the water entering the wiring trough 4122 can be discharged into the first water tank 13 through the second drainage hole 4121, thereby reducing the possibility of water accumulating in the wiring trough 4122, protecting the wiring from water immersion and corrosion, and improving the safety and stability of the electrical system. Moreover, when water is discharged from the second drainage hole 4121, the water-blocking rib 11 intercepts the water from entering the indoor unit component 2, thereby preventing water from entering the room.

[0133] For example, the first drain hole 52 can be located above and connected to the wiring trough 4122. When water (such as accidental water ingress, rainwater, etc.) enters the air conditioner and flows to the partition 5 and the surrounding area, the first drain hole 52 can orderly introduce the water into the wiring trough 4122, preventing excessive water accumulation on the top surface of the partition 5 and disorderly leakage into the wiring trough 4122, which may cause electrical short circuits and other risks. The second drain hole 4121 formed at the bottom of the wiring section 412 is connected to the wiring trough 4122, so that the water entering the wiring trough 4122 can be further drained to the chassis 1 through the second drain hole 4121, thereby reducing the possibility of water accumulating in the wiring trough 4122, protecting the wiring from water immersion and corrosion, and improving the safety and stability of the electrical system.

[0134] In some embodiments, reference Figures 2-3 , Figure 9 The chassis 1 includes a platform portion 17, a portion of which is located below the accommodating space 100a and supports the base 41. A first water tank 13 is recessed relative to the platform portion 17. The first water tank 13 includes a water collection tank 131, which is located between the platform portion 17 and the water-blocking rib 11.

[0135] In the above technical solution, the platform portion 17 provides a stable base plane for the installation of the base 41. The platform portion 17 supports the base 41, and the base 41, in turn, supports other components, thus making the installation of the base 41 and the components installed on the base 41 relatively stable. When water or the like enters the receiving space 100a, a portion of the platform portion 17 is located below the receiving space 100a, causing the water to flow towards the platform portion 17. The first water tank 13 is recessed relative to the platform portion 17, forming a water collection area. Water then flows down into the first water tank 13, achieving water collection.

[0136] Furthermore, the first water tank 13 may also include a water guide trough 132, which extends from the water collection tank 131 to the bottom of the outdoor unit assembly 3, and the first drainage path 100b connects to the water guide trough 132, thus achieving orderly water discharge. The water collected in the water collection tank 131 can be smoothly discharged to the outside of the air conditioner through the water guide trough 132, preventing water from entering the chassis 1 and reducing the possibility of water intrusion into the room.

[0137] In some embodiments, the water-blocking structure 10 is integrally formed on the chassis 1, which is a one-piece stamped part. The one-piece chassis 1 has no seams or connecting parts, and when subjected to various forces (such as gravity, vibration, etc.) generated during operation from the indoor unit 2 and outdoor unit 3, it can evenly distribute these forces across the entire chassis 1 structure, improving the overall structural strength and stability of the air conditioner. Furthermore, the one-piece structure allows for more flexible and rational drainage design of the chassis 1, reducing assembly and facilitating processing. Various shapes and sizes of drainage structures, such as water tanks and drain holes, can be integrally formed on the chassis 1 according to the actual needs of the air conditioner, ensuring that condensate can be smoothly and quickly discharged outside the air conditioner. Moreover, since there are no seams, water will not accumulate or backflow at the seams during drainage, improving drainage efficiency and waterproofing. Furthermore, the one-piece stamping process is simple and easy to manufacture, and the overall structural strength of the chassis 1 is good.
