[0052] With technological advancements and rising living standards, window air conditioners have gradually become a common feature of people's lives. As a compact air conditioner that can be installed on a window, a window air conditioner is a single unit. One part of the unit is located indoors, while the other is located outdoors. The condenser and evaporator are arranged horizontally, regulating the indoor temperature.

[0053] In order to prevent the noise generated by the compressor, outdoor fan and other components of the window air conditioner from affecting users, the compressor, outdoor fan and other components of the window air conditioner are usually isolated on the outdoor side to achieve a silent effect.

[0054] However, some window air conditioners have fixed indoor and outdoor units relative to each other. The indoor unit is positioned low, which results in a lower air outlet, impacting the cooling effect. Furthermore, window air conditioners typically use copper or aluminum pipes for refrigerant piping, which results in a fixed position relative to other components within the unit, making it difficult for the indoor unit to move up and down relative to the outdoor unit.

[0055] To address the aforementioned technical issues, some embodiments of the present disclosure provide a window air conditioner 100. The indoor unit of the window air conditioner 100 can slide up and down via a sliding assembly, allowing the user to adjust the height of the indoor unit's air outlet as needed, thereby improving the cooling effect of the window air conditioner. Furthermore, the refrigerant piping of the window air conditioner 100 is deformable, facilitating the vertical movement of the indoor unit relative to the outdoor unit via the sliding assembly.

[0056] Below, for the convenience of description, as shown in Figure 1, the front and rear direction of the window air conditioner 100 (i.e., the arrangement direction of the indoor unit and the outdoor unit) is defined as a first direction A (i.e., a first predetermined direction), the left and right direction of the window air conditioner 100 is defined as a second direction B, and the up and down direction (i.e., the height direction) of the indoor unit 1 is defined as a third direction C (i.e., a second predetermined direction).

[0057] In some embodiments, the window air conditioner 100 can be installed on a wall having a mounting opening (eg, a window), wherein a first portion of the window air conditioner 100 is located outdoors, and a second portion of the window air conditioner 100 is located indoors.

[0058] 1 and 2 , the window air conditioner 100 includes an outdoor unit 1 (ie, a first portion of the window air conditioner 100 ). The outdoor unit 1 is located outdoors.

[0059] The outdoor unit 1 includes a compressor 101. The compressor 101 is configured to compress refrigerant, converting low-pressure refrigerant into high-pressure refrigerant. The compressor 101 includes an exhaust port and a return port. Low-pressure refrigerant enters the compressor 101 through the return port. The compressor 101 compresses the low-pressure refrigerant into high-pressure refrigerant before discharging it through the exhaust port. This high-pressure refrigerant releases heat in the condenser. Then, after being decompressed, the refrigerant absorbs heat in the evaporator. Finally, the refrigerant enters the compressor 101 through the return port, continuing the cycle.

[0060] The outdoor unit 1 further includes a first heat exchanger 102 (outdoor heat exchanger). The first heat exchanger 102 is configured to exchange heat between outdoor air and the refrigerant transported through the first heat exchanger 102. For example, when the window air conditioner 100 is in cooling mode, the first heat exchanger 102 operates as a condenser, and the exhaust port of the compressor 101 is connected to the first heat exchanger 102. When the window air conditioner 100 is in heating mode, the first heat exchanger 102 operates as an evaporator, and the return air port of the compressor 101 is connected to the first heat exchanger 102.

[0061] The outdoor unit 1 further includes a pressure reducer 103. The pressure reducer 103 is connected between the second heat exchanger 104 and the first heat exchanger 102 of the indoor unit. The opening of the pressure reducer 103 adjusts the pressure of the refrigerant flowing through the second heat exchanger 104 and the first heat exchanger 102, thereby adjusting the refrigerant flow rate between the second heat exchanger 104 and the first heat exchanger 102.

[0062] The outdoor unit 1 further includes a four-way valve disposed in the refrigerant circuit and configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the window type air conditioner 100 operates in a cooling mode or a heating mode.

[0063] The outdoor unit 1 further includes a first fan 105 (outdoor fan). The first fan 105 is configured to draw outdoor air into the outdoor unit 1 through a first air inlet and to deliver the outdoor air, after heat exchange with the first heat exchanger 102, through a first air outlet of the outdoor unit 1. The first fan 105 provides power for the flow of outdoor air.

[0064] In some embodiments, the outdoor unit 1 further includes a first housing 11. The first housing 11 includes a first passage (outdoor air passage). A first air inlet and a first air outlet are formed in the first housing 11 and communicate with the first passage.

[0065] For example, the first air outlet is located on a side of the first housing 11 away from the indoor unit 2, so that outdoor air enters the first housing 11 from the first air inlet and is then discharged from the first air outlet.

[0066] In some embodiments, as shown in Figures 1 and 2, the window air conditioner 100 further includes an indoor unit 2 (i.e., the first portion of the window air conditioner 100). The indoor unit 2 is located indoors. The outdoor unit 1 and the indoor unit 2 are integrally formed and connected by a pipeline to transmit refrigerant.

[0067] The indoor unit 2 includes a second heat exchanger 104 (indoor heat exchanger). The second heat exchanger 104 is configured to exchange heat between indoor air and a refrigerant transmitted through the second heat exchanger 104. For example, the second heat exchanger 104 operates as an evaporator in the cooling mode of the window air conditioner 100 and operates as a condenser in the heating mode of the window air conditioner 100.

[0068] The compressor 101, the first heat exchanger 102, the pressure reducer 103 (such as an expansion valve or a capillary tube) and the second heat exchanger 104 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the second heat exchanger 104 and the first heat exchanger 102 respectively, thereby realizing the cooling mode or heating mode of the window air conditioner 100.

[0069] The indoor unit 2 further includes a second fan 106 (indoor fan). The second fan 106 is configured to draw indoor air into the indoor unit 2 through the second air inlet of the indoor unit 2 and to deliver the indoor air, after heat exchange with the second heat exchanger 104, through the second air outlet of the indoor unit 2. The second fan 106 provides power for the flow of indoor air.

[0070] For example, the first fan 105 and the second fan 106 are cross-flow fans, which can push or draw air along the fan axis, thereby increasing the air volume and air pressure. In addition, the user can also adjust the air volume of the window air conditioner 100 by controlling the speed of the first fan 105 and the second fan 106.

[0071] In some embodiments, the indoor unit 2 includes a second housing 12. A second passage (indoor air passage) is formed within the second housing 12. A second air inlet and a second air outlet (air outlet) are formed in the second housing 12 and communicate with the second passage. The second air outlet is located on a side of the second housing 12 away from the outdoor unit 1, allowing indoor air to enter the second housing 12 through the second air inlet and be discharged into the room through the second air outlet.

[0072] In some embodiments, the first housing 11 and the second housing 12 are connected. For example, a portion of the second housing 12 passes through a window or a wall to connect with the first housing 11.

[0073] 1 , the window air conditioner 100 further includes a connecting device 3 (connecting bridge portion). The first housing 11 and the second housing 12 are spaced apart and connected by the connecting device 3 .

[0074] For example, at least a portion of the connecting device 3 is located in a window or in a wall. Along a first direction A, a first end of the connecting device 3 is connected to the indoor unit 2, and a second end of the connecting device 3 is connected to the outdoor unit 1. As a result, the outdoor unit 1 and the indoor unit 2 are respectively clamped against the wall from both sides, thereby improving the stability of the window air conditioner 100 and enhancing the reliability of the installation of the window air conditioner 100.

[0075] In some embodiments, the connecting device 3 includes a third housing 13 (connecting bridge housing), which is connected to the first housing 11 and the second housing 12 along the first direction A. For example, a first end of the third housing 13 is connected to a side of the first housing 11 facing the second housing 12, and a second end of the third housing 13 is connected to a side of the second housing 12 facing the first housing 11.

[0076] The second housing 12 is movable relative to the third housing 13 along the third direction C (i.e., the first and second predetermined directions). For example, the second housing 12 and the third housing 13 are slidably connected, so that the second housing 12 can move relative to the third housing 13 along the third direction C to adjust the height of the second air outlet, thereby improving the cooling effect of the window air conditioner 100.

[0077] In some embodiments, as shown in FIG. 2 , the window air conditioner 100 further includes a pipe assembly 40 (refrigerant pipe), and the pipe assembly 40 is respectively connected to the compressor 101 and the second heat exchanger 104 .

[0078] When window air conditioner 100 operates in cooling mode, refrigerant is discharged from the exhaust port of compressor 101 and passes through first heat exchanger 102, exchanging heat with first heat exchanger 102 to release heat. The refrigerant, having released heat, is then reduced in pressure by pressure reducer 103 and flows through a refrigerant circuit to second heat exchanger 104. There, the refrigerant absorbs heat from the indoor air and then returns to compressor 101 along piping assembly 40. The indoor air, having exchanged heat, then flows into the room, thus achieving cooling mode.

[0079] When window air conditioner 100 operates in heating mode, refrigerant is discharged from the exhaust port of compressor 101 and flows through piping assembly 40 to first heat exchanger 102, exchanging heat with first heat exchanger 102 and releasing heat, thereby achieving heating. The refrigerant, having released heat, then passes through pressure reducer 103 to reduce pressure before flowing through the refrigerant circuit to first heat exchanger 102. There, the refrigerant absorbs heat from the outdoor air and then returns to compressor 101 through the return air port.

[0080] In some embodiments, as shown in FIG. 2 and FIG. 3 , the pipeline assembly 40 includes a first pipeline 41 and a second pipeline 42 .

[0081] The first end of the first pipeline 41 is connected to the second heat exchanger 104, the second end of the first pipeline 41 is connected to the first end of the second pipeline 42, and the second end of the second pipeline 42 is connected to the compressor 101. The second pipeline 42 is disposed within the third housing 13. At least a portion of the first pipeline 41 is disposed within the second housing 12 and is bent relative to the third direction C. The first pipeline 41 and the second pipeline 42 are in communication, allowing refrigerant to flow through the first pipeline 41 and the second pipeline 42.

[0082] For example, the first end of the first conduit 41 is located to one side of the second end of the first conduit 41 along the third direction C, and the middle portion of the first conduit 41 protrudes horizontally. For example, the first conduit 41 is an arc-shaped tube and is deformable. Thus, when the second housing 12 moves relative to the third housing 13 along the third direction C, the dimension of the first conduit 41 along the third direction C can increase or decrease, thereby facilitating the movement of the second housing 12 relative to the third housing 13 and adjusting the height of the indoor air outlet.

[0083] For example, the first pipe 41 can be telescopic (lengthened or shortened) to facilitate the movement of the second housing 12 relative to the third housing 13 .

[0084] In some embodiments, the second housing 12 is configured to move between a first position and a second position relative to the third housing 13. When the second housing 12 is in the first position, see FIG1 , the top wall of the third housing 13 is substantially flush with the top wall of the second housing 12. When the second housing 12 is in the second position, see FIG4 , the top wall of the second housing 12 is higher than the top wall of the third housing 13 along the third direction C.

[0085] For example, when the second housing 12 moves from the first position to the second position, the dimension of the first pipe 41 along the third direction C increases, and when the second housing 12 moves from the second position to the first position, the dimension of the first pipe 41 along the third direction C decreases. In this way, the height difference between the second housing 12 and the third housing 13 can be compensated, thereby adjusting the air outlet height of the indoor unit 2 and improving the cooling effect of the window air conditioner 100.

[0086] In some embodiments, the second housing 12 includes a first sub-housing 121 and a back plate 122. The back plate 122 is located on the side of the second housing 12 facing the first housing 11. The back plate 122 is slidably connected to the third housing 13 and fixedly connected to the first sub-housing 121, thereby allowing the second housing 12 to move relative to the third housing 13 along the third direction C.

[0087] The second housing 12 further includes a receiving space. The back plate 122 and the first sub-housing 121 together define the receiving space. The second fan 106 and the second heat exchanger 104 are located in the receiving space.

[0088] In some embodiments, as shown in FIG5 , the second housing 12 further includes a first opening 125 (opening slot). The first opening 125 is disposed in the back plate 122 and extends along the third direction C. The first conduit 41 connects to the second conduit 42 through the first opening 125. When the second housing 12 moves relative to the third housing 13, the first conduit 41 moves along the third direction C relative to the first opening 125.

[0089] The first portion of the first pipeline 41 is located within the second housing 12, and the second portion of the first pipeline 41 is located within the third housing 13. The connection between the first pipeline 41 and the second pipeline 42 is located within the third housing 13. Thus, when the second housing 12 moves relative to the third housing 13, the first pipeline 41 deforms, while the position of the connection between the first pipeline 41 and the second pipeline 42 remains unchanged, thereby improving the stability and reliability of the connection between the first pipeline 41 and the second pipeline 42.

[0090] In some embodiments, the first position and the second position are the extreme positions of movement of the second housing 12 relative to the third housing 13. When the second housing 12 is in the first position, the first conduit 41 abuts against the inner bottom wall of the first opening 125. When the second housing 12 is in the second position, the first conduit 41 abuts against the inner top wall of the first opening 125. Thus, the first opening 125 can limit the first conduit 41 to a certain extent, which helps to improve the stability and reliability of the movement of the first conduit 41.

[0091] In some embodiments, as shown in Figure 3, the first end of the first pipeline 41 is fixed relative to the first sub-shell 121, so that when the second shell 12 moves relative to the third shell 13, the height of the second end of the first pipeline 41 remains unchanged, and the height of the first end of the first pipeline 41 moves along the third direction C with the second shell 12.

[0092] 3 and 6 , the window air conditioner 100 further includes a first fixing assembly 61 . The first fixing assembly 61 is disposed in the second housing 12 and is configured to fix the first end of the first pipe 41 .

[0093] For example, the first fixing assembly 61 is located at the lower portion of the second housing 12 and is spaced apart from the second heat exchanger 104. The first fixing assembly 61 can fix the end (i.e., the first end) of the first pipe 41 connected to the second heat exchanger 104 at a predetermined position, thereby facilitating improved stability of the first pipe 41 as it moves with the second housing 12.

[0094] In some embodiments, as shown in Figures 6 and 7, the first fixing assembly 61 includes a first fixing portion 611. The first fixing portion 611 is fixedly connected to the second housing 12. The first fixing assembly 61 also includes a second fixing portion 612. The second fixing portion 612 is fixedly connected to the first fixing portion 611, and the first end of the first pipeline 41 is fixedly disposed between the second fixing portion 612 and the first fixing portion 611.

[0095] For example, a third hole 613 is defined between the first fixing portion 611 and the second fixing portion 612. The third hole 613 is, for example, a fixing hole. The first end of the first pipe 41 is disposed in the fixing hole, and the fixing hole can compress the first pipe 41 in the radial direction of the first pipe 41, thereby fixing the first end of the first pipe 41 relative to the second housing 12 and preventing the first pipe 41 from becoming tangled when moving in the height direction of the second housing 12, thereby preventing abnormal noise from being generated.

[0096] In some embodiments, as shown in Figures 5 and 6, the second housing 12 further includes a base 123. The base 123 is located below the first sub-housing 121 and is fixedly connected to the first sub-housing 121. The base 123 extends horizontally. For example, the first fixing assembly 61, the second fan 106, and the second heat exchanger 104 are fixed to the base 123.

[0097] In some embodiments, the second housing 12 further includes a partition 124, which is located within the first sub-housing 121, and the lower end of the partition 124 is fixedly connected to the base 123. The partition 124 and the base 123 together define a fifth hole 63, and a portion of the first pipeline 41 is disposed in the fifth hole 63. The fifth hole 63 is configured to secure the first pipeline 41 to limit the position of the first pipeline 41.

[0098] For example, the partition 124 is located between the first fixing assembly 61 and the second fan 106 to separate the first pipe 41 from the second heat exchanger 104 and to separate the first pipe 41 from the second fan 106 .

[0099] For example, the first pipeline 41 passes through the fifth hole 63 , and the fifth hole 63 squeezes the first pipeline 41 along the radial direction of the first pipeline 41 , thereby limiting the first pipeline 41 , thereby facilitating improving the stability of movement and deformation of the first pipeline 41 .

[0100] In some embodiments, as shown in FIG3 , the second end of the first pipe 41 is fixed relative to the third housing 13. For example, the connection between the first pipe 41 and the second pipe 42 is fixed relative to the third housing 13, thereby facilitating the arrangement of the first pipe 41 and the second pipe 42 and preventing the first pipe 41 from losing control during movement and deformation, thereby generating abnormal noise.

[0101] In some embodiments, as shown in FIG8 , the window air conditioner 100 further includes a second fixing assembly 62 disposed within the third housing 13. The second fixing assembly 62 is configured to fix the second end of the first pipe 41 so that the second end of the first pipe 41 remains fixed relative to the third housing 13 during movement of the second housing 12.

[0102] For example, the second fixing assembly 62 includes a third fixing portion 621 and a fourth fixing portion 622. The third fixing portion 621 is fixedly connected to the third housing 13. The fourth fixing portion 622 is fixedly connected to the third fixing portion 621 and, together with the third fixing portion 621, defines a fourth hole 623. The second end of the first pipeline 41 is disposed in the fourth hole 623, which limits and secures the second end of the first pipeline 41, thereby facilitating the layout of the first pipeline 41.

[0103] 9 , the window air conditioner 100 further includes a first sliding assembly 110. The first sliding assembly 110 is fixedly connected to the third housing 13 and the back panel 122, respectively, so that the back panel 122 can slide relative to the third housing 13 along the third direction C via the first sliding assembly 110.

[0104] In some embodiments, as shown in Figures 9 and 10, the first sliding assembly 110 includes a first sliding portion 111 and a second sliding portion 112. The first sliding portion 111 is fixedly connected to the back plate 122, and the second sliding portion 112 is fixedly connected to the third housing 13. The first sliding portion 111 and the second sliding portion 112 are slidably connected, so that the back plate 122 can slide relative to the third housing 13 along the third direction C via the first sliding assembly 110, thereby increasing the height of the air outlet of the indoor unit 2 and improving the cooling effect of the window air conditioner 100.

[0105] For example, one of the first sliding portion 111 and the second sliding portion 112 is a slide rail, and the other of the first sliding portion 111 and the second sliding portion 112 is a slide groove. The slide rail matches the slide groove and can slide in the slide groove.

[0106] In some embodiments, as shown in FIG. 9 , the third housing 13 includes a second sub-housing 131 (first bridge section). The second sub-housing 131 is located on a side of the first housing 11 close to the second housing 12 and is fixedly connected to the first housing 11 .

[0107] The third housing 13 further includes a third sub-housing 132 (second bridge section), which is located on a side of the first sub-housing 121 close to the first housing 11 . The back plate 122 is slidably connected to the third sub-housing 132 via the first sliding assembly 110 .

[0108] The third sub-housing 132 is disposed inside the second sub-housing 131 and is movable relative to the second sub-housing 131. For example, the third sub-housing 132 can move relative to the second sub-housing 131 in a first direction A, thereby causing the second housing 12 to move relative to the first housing 11 in the first direction A. This allows the window air conditioner 100 to be adapted for windows or walls of varying thicknesses, thereby improving the adaptability of the window air conditioner 100.

[0109] In some embodiments, the middle portion of the second conduit 42 protrudes horizontally. For example, the second conduit 42 is an arc-shaped tube. The tube body of the second conduit 42 is deformable. Thus, when the second housing 12 moves relative to the first housing 11 in the first direction A, the dimension of the second conduit 42 in the first direction A can increase or decrease, thereby facilitating the movement of the second housing 12 relative to the first housing 11 and adjusting the distance between the second housing 12 and the first housing 11.

[0110] In some embodiments, as shown in FIG9 , the first end of the second pipeline 42 is fixed relative to the second sub-shell 131 (i.e., fixed relative to the first shell 11 ), so that the position of the connection between the second pipeline 42 and the compressor 101 is fixed, facilitating the arrangement of the second pipeline 42 .

[0111] It can be understood that since the second sub-shell 131 is fixedly connected to the first shell 11 and the second sub-shell 131 is slidingly connected to the third sub-shell 132, the position of the first end of the second pipeline 42 remains fixed, and the second end of the second pipeline 42 moves along the first direction A with the third sub-shell 132 and the second shell 12. During the movement of the second pipeline 42 along the first direction A of the second shell 12, the curvature changes (deforms), so that the size of the second pipeline 42 in the first direction A increases or decreases.

[0112] In some embodiments, as shown in Figures 11 and 12, the window air conditioner 100 further includes a third fixing assembly 64. The third fixing assembly 64 is disposed within the third housing 13 and adjacent to the first housing 11. The first end of the second pipe 42 is secured within the third fixing assembly 64. For example, the third fixing assembly 64 secures the second pipe 42 radially along the second pipe 42, thereby facilitating the layout of the second pipe 42.

[0113] In some embodiments, as shown in FIG12 , the third fixing assembly 64 includes a fifth fixing portion 641 and a sixth fixing portion 642. The fifth fixing portion 641 is fixedly connected to the second sub-housing 131, and the sixth fixing portion 642 is fixedly connected to the fifth fixing portion 641. The fifth fixing portion 641 and the sixth fixing portion 642 together define a fourth fixing portion 643. The first end of the second pipeline 42 is fixedly disposed in the fourth fixing portion 643.

[0114] For example, the fourth fixing portion 643 clamps and fixes the second pipeline 42 along the radial direction of the second pipeline 42, thereby preventing the second pipeline 42 from getting out of control and generating abnormal noise during the movement of the second shell 12.

[0115] In some embodiments, as shown in Figures 13 and 14, the window air conditioner 100 further includes a second sliding assembly 140. The second sliding assembly 140 is disposed between the second sub-housing 131 and the third sub-housing 132 and is fixedly connected to the second sub-housing 131 and the third sub-housing 132, respectively. In this way, the second sub-housing 131 is slidably connected to the third sub-housing 132 via the second sliding assembly 140.

[0116] For example, the second sliding assembly 140 includes a third sliding portion 141 , which is fixedly connected to the second sub-housing 131 and located on a side (eg, inner side) of the second sub-housing 131 facing the third sub-housing 132 .

[0117] For example, the second sliding assembly 140 further includes a fourth sliding portion 142, which is fixedly connected to the third sub-housing 132 and is located on a side (e.g., an outer side) of the third sub-housing 132 that faces the second sub-housing 131. The third sliding portion 141 is slidably connected to the fourth sliding portion 142, thereby achieving a sliding connection between the second sub-housing 131 and the third sub-housing 132.

[0118] For example, one of the third sliding portion 141 and the fourth sliding portion 142 is a slide rail, and the other of the third sliding portion 141 and the fourth sliding portion 142 is a slide groove. The slide rail matches the slide groove and can slide in the slide groove.

[0119] In some embodiments, as shown in Figures 11 and 13, the window air conditioner 100 also includes an insulation component 44 (such as a foam tube or a foam tube), which is sleeved on the outer peripheral side of the pipeline assembly 40, thereby blocking the heat transfer between the refrigerant in the first pipeline 41 and the second pipeline 42 and the air to a certain extent, which is beneficial to reducing the heat loss of the refrigerant in the first pipeline 41 and the second pipeline 42, and further beneficial to improving the heat exchange efficiency of the first heat exchanger 102 and the second heat exchanger 104.

[0120] 15 and 16 , the second housing 12 further includes a water collecting portion 127 (water collecting tank). The water collecting portion 127 is located on a side of the base 123 facing the first sub-housing 121 and is configured to collect condensed water.

[0121] For example, the water collecting tank is located on a side of the base 123 facing the first sub-housing 121 and is recessed in a direction away from the first sub-housing 121 .

[0122] In some embodiments, as shown in FIG17 , the second housing 12 further includes a water receiving portion 128 (water receiving trough), which is disposed on a side of the base 123 facing the first sub-housing 121 and located on one side of the water collecting portion 127. The water receiving portion 128 corresponds to the position of the second heat exchanger 104 and is configured to receive condensed water falling from the second heat exchanger 104.

[0123] For example, along the third direction C, the height of the water receiving trough is higher than that of the water collecting trough, and the water receiving trough is connected to the water collecting trough, so that the condensed water on the second heat exchanger 104 can first drip into the water receiving trough, and then flow into the water collecting trough under the action of gravity.

[0124] In some embodiments, as shown in Figure 18, the window air conditioner 100 also includes a water pump assembly 500, which is disposed in the first shell 11 and is configured to pump the condensed water stored in the water collection portion 127 to the outside of the first shell 11 or to the first fan 105.

[0125] It can be understood that when the water pump assembly 500 transports the condensed water to the first fan 105, the water pumping ring in the first fan 105 can disperse the condensed water onto the first heat exchanger, thereby improving the heat exchange effect of the first heat exchanger, thereby improving the cooling or heating effect of the window air conditioner 100 and reducing the energy consumption of the window air conditioner 100.

[0126] In some embodiments, as shown in Figures 15 and 16 , the window air conditioner 100 further includes a mounting assembly 160 (mounting plate). The mounting assembly 160 is disposed on the base 123 and spaced apart from the water collecting portion 127 along the third direction C (e.g., the mounting assembly 160 is located above the water collecting portion 127). The mounting assembly 160 includes at least one first hole 161 (fixing hole).

[0127] The window air conditioner 100 also includes a switch assembly 150 (water level switch). The switch assembly 150 is mounted within at least one first hole 161 to be fixedly connected to the mounting assembly 160. One end of the switch assembly 150 (i.e., the lower end) near the base 123 is located within the water collection portion 127. The switch assembly 150 is coupled to the water pump assembly 500 and is configured to control the water pump assembly 500 to start when the water level within the water collection portion 127 reaches a first predetermined height, thereby causing the water pump assembly 500 to pump condensed water from the water collection portion 127. For example, the switch assembly 150 is further configured to control the water pump assembly 500 to stop when the water level within the water collection portion 127 falls below a second predetermined height. For example, the first predetermined height is greater than or equal to the second predetermined height.

[0128] In this way, by setting a switch assembly 150 above the water collecting portion 127 and controlling the start or shut down of the water pump assembly 500 through the switch assembly 150, it is possible to avoid excessive condensed water in the water collecting portion 127 from overflowing, which is beneficial to improving the drainage reliability of the water pump assembly 500, and can avoid the water pump assembly 500 from continuing to work when the water level of the condensed water in the water collecting portion 127 is too low, thereby helping to reduce the energy consumption of the window air conditioner 100.

[0129] In some embodiments, as shown in FIG16 , the switch assembly 150 includes a first switch 151 (a first water level switch). The first switch 151 is mounted in one of the at least one first holes 161 to be fixedly connected to the mounting assembly 160. One end of the first switch 151 (e.g., the lower end) near the base 123 is located within the water collection portion 127. The first switch 151 is coupled to the water pump assembly 500 and is configured to activate the water pump assembly 500 when the water level within the water collection portion 127 rises to contact the first switch 151 (e.g., when the water level reaches a first predetermined height), causing the water pump assembly 500 to pump condensed water from the water collection portion 127 to the outside of the room. For example, the first switch 151 is further configured to deactivate the water pump assembly 500 when the water level within the water collection portion 127 drops below the first switch 151 (e.g., when the condensed water no longer contacts the first switch 151, e.g., when the water level drops to a second predetermined height). This is beneficial to improving the drainage reliability of the water pump assembly 500 and reducing the energy consumption of the window air conditioner 100.

[0130] In some embodiments, as shown in FIG16 , the switch assembly 150 further includes a second switch 152. The second switch 152 is correspondingly mounted within another first hole 161 of the at least one first hole 161, with one end of the second switch 152 proximal to the base 123 (i.e., the lower end) positioned within the water collection portion 127. The second switch 152 is spaced apart from the first switch 151, and along the third direction C, the end of the second switch 152 proximal to the base 123 is higher than the end of the first switch 151 proximal to the base 123. The second switch 152 is coupled to the water pump assembly 500 and is configured to control the window air conditioner 100 to shut down (i.e., power down) when the water level within the water collection portion 127 rises to contact the second switch 152.

[0131] It is understood that when the pumping capacity of the water pump assembly 500 decreases due to a malfunction or other reasons, or even when it is unable to pump condensed water, the condensed water in the water collecting portion 127 cannot be discharged. Therefore, after contacting the first switch 151, the condensed water will continue to rise until it contacts the second switch 152. In this case, the second switch 152 can control the window air conditioner 100 to stop operating, thereby preventing the condensed water from continuing to generate, accumulate, and overflow from the base 123.

[0132] In some embodiments, as shown in FIG17 , the second housing 12 further includes a drain port 27 formed in a sidewall of the base 123 and communicating with the water collection portion 127. For example, the water collection portion 127 communicates with the exterior of the second housing 12 through the drain port 27. The second housing 12 further includes a valve 28 disposed at the drain port 27 and connected to the base 123. The valve 28 is configured to open or close the drain port 27.

[0133] It is understood that when the drain port 27 is closed, the water collecting portion 127 can store condensed water. When the drain port 27 is opened, the water collecting portion 127 communicates with the outside of the second housing 12 through the drain port 27, so that the condensed water in the water collecting portion 127 can be discharged to the outside of the second housing 12 through the drain port 27.

[0134] In this way, when the water level in the water collection part 127 rises to contact the second switch 152, and the second switch 152 controls the window air conditioner 100 to be closed, the user can open the drain outlet through the valve 28 to drain the condensed water in the water collection part 127. In this way, the condensed water can be prevented from overflowing from the base 123, and the condensed water in the water collection part 127 is discharged through the drain outlet 27, which makes it easier for maintenance personnel to repair the window air conditioner 100.

[0135] In some embodiments, as shown in FIG. 17 , valve 28 includes a valve body 21, which is located at drain port 27 and fixedly connected to base 123. Valve 28 also includes a seal 29, which is disposed between valve body 21 and drain port 27 and is configured to seal the gap between valve body 21 and drain port 27, thereby improving the sealing performance of valve 28 and allowing condensed water to be stored in water collection portion 127.

[0136] In some embodiments, the valve 28 further includes a filter 23. The filter 23 is disposed on a side of the seal 29 facing the drain port 27. The filter 23 is configured to filter solid impurities in the condensed water to prevent the solid impurities from entering the valve body 21 and affecting the opening and closing of the valve body 21.

[0137] 15 and 16 , the window air conditioner 100 further includes a first water pipe 170 . A first end of the first water pipe 170 is connected to the water inlet of the water pump assembly 500 , and a second end of the first water pipe 170 is located in the water collecting portion 127 .

[0138] As shown in FIG15 , the window air conditioner 100 further includes a second water pipe 180. A first end of the second water pipe 180 is connected to the water outlet of the water pump assembly 500, and a second end of the second water pipe 180 is located outdoors (e.g., within the first housing 11) and near the first heat exchanger 102. Thus, when the water pump assembly 500 is activated, condensed water in the water collecting portion 127 can be sucked through the first water pipe 170 and transported to the outdoors through the second water pipe 180.

[0139] In some embodiments, as shown in FIG16 , the mounting assembly 160 further includes a first connecting portion 162 (water pipe connector). At least a portion of the first water pipe 170 (e.g., the portion near the water collecting portion 127) is disposed in the first connecting portion 162. The first connecting portion 162 is configured to secure and position the first water pipe 170. For example, the first connecting portion 162 is configured as a fixing hole, the inner diameter of the fixing hole being substantially the same as the outer diameter of the first water pipe 170. The first water pipe 170 is provided with the fixing hole, thereby securing and position-limiting the first water pipe 170.

[0140] It can be understood that by fixing and limiting the first water pipe 170 through the first connecting portion 162, the first water pipe can be prevented from being misplaced due to the vibration generated when the water pump assembly 500 is working, which is beneficial to improving the reliability of the water pump assembly 500 in sucking condensed water. In addition, there is no need to set up additional components for fixing the first water pipe 170 in the window air conditioner 100, thereby simplifying the internal structure of the window air conditioner 100 and reducing costs.

[0141] In some embodiments, as shown in FIG19 , a portion of the first water pipe 170 is disposed within the accommodation space, and at least a portion of the first water pipe 170 engages with the fourth hole 623 and is fixedly disposed within the fourth hole 623. Thus, the fourth hole 623 can limit the first water pipe 170, thereby facilitating the arrangement of the internal piping of the window air conditioner 100.

[0142] In some embodiments, as shown in Figure 2, mounting assembly 160 further includes a fifth fixing portion 163 and a first body 164. Fifth fixing portion 163 is disposed on first body 164 and protrudes upward. First water pipe 170 passes through fifth fixing portion 163 and engages with fifth fixing portion 163. Fifth fixing portion 163 can position first water pipe 170, thereby facilitating the layout of the internal piping of window air conditioner 100.

[0143] In some embodiments, as shown in Figures 15 and 19 , the second housing 12 further includes a guide portion 126 (pre-fixed groove). The guide portion 126 is disposed on the top of the partition 124 and is recessed (e.g., recessed downward) toward the interior of the partition 124. The first pipeline 41 and the first water pipe 170 are fixedly disposed within the guide portion 126 along the extension direction of the guide portion 126. The guide portion 126 is configured to guide and position the first pipeline 41 and the first water pipe 170, thereby facilitating the layout of the internal piping of the window air conditioner 100.

[0144] In some embodiments, as shown in Figures 20 and 21, the mounting assembly 160 further includes a first engaging portion 165, which is connected to the first body 164. The second housing 12 further includes a second engaging portion 129. The second engaging portion 129 is disposed on a side of the base 123 facing the mounting assembly 160. The first engaging portion 165 corresponds to the position of the second engaging portion 129 and engages with the second engaging portion 129 to connect the mounting assembly 160 to the base 123.

[0145] For example, the first clamping portion 165 is one of a buckle and a slot, and the second clamping portion 129 is the other of the buckle and the slot. The buckle and the slot are engaged with each other, thereby connecting the mounting assembly 160 to the base 123.

[0146] In some embodiments, as shown in FIG. 21 , the mounting assembly 160 further includes a second hole 166 (first mounting hole). The second hole 166 is disposed in the first body 164 and passes through the first body 164 .

[0147] The second housing 12 also includes a third hole (second mounting hole) disposed in the base 123. The third hole corresponds to the position of the second hole 166 and opens toward the second hole 166. A fastener (e.g., a screw) is passed through the second hole 166 and the third hole to securely connect the mounting assembly 160 to the base 123.

[0148] In some embodiments, as shown in Figures 22 to 24, the water pump assembly 500 is located within the first housing 11 and is fixedly connected to the third housing 13. The water pump assembly 500 includes a water pump 510 and a waterproof member 520. The water pump 510 is disposed within the waterproof member 520, thereby isolating the water pump 510 from the external environment (outside the waterproof member 520) to prevent liquid (such as droplets from the water ring in the first fan 105) from splashing onto the water pump 510 and causing a short circuit in the water pump 510.

[0149] It is understandable that by providing the waterproof member 520 on the outside of the water pump 510 , the waterproof performance of the water pump assembly 500 can be improved, and the assembly efficiency of the window air conditioner 100 can be improved.

[0150] In some embodiments, as shown in Figures 24 and 25 , the waterproof member 520 includes a second body 528 and a first flange 521 (first waterproof flange). The first flange 521 is disposed on top of the second body 528 and above the water pump 510. The first flange 521 folds toward the third housing 13 to form a first escape portion 522 (first escape groove). A portion of the first water pipe 170 is disposed in the first escape portion 522.

[0151] In this way, the first flange portion 521 can cover the top of the water pump 510, thereby preventing the condensed water brought up by the rotation of the first fan 105 from splashing onto the water pump 510, causing a short circuit in the water pump 510, and the first flange portion 521 can also cover a part of the first water pipe 170, thereby preventing the condensed water from splashing onto the first water pipe 170 and flowing along the first water pipe 170 to the water pump 510, causing a short circuit in the water pump.

[0152] For example, the first escape portion 522 is configured as a first escape groove that opens toward the third housing 13. The first water pipe 170 extends along the first direction A into the first escape groove and then bends downward to connect with the water inlet of the water pump 510. This facilitates the connection between the first water pipe 170 and the water pump 510 and prevents condensed water from entering the water pump assembly 500 along the first water pipe 170.

[0153] In some embodiments, as shown in Figures 24 and 25 , the waterproof member 520 further includes two second flanges 523 (second waterproof flanges). Along the second direction B, the two second flanges 523 connect to two sides of the second body 528 and are located on either side of the water pump 510. The second flanges 523 are folded toward the third housing 13.

[0154] In this way, the two second flange portions 523 can respectively cover both sides of the water pump 510 , thereby preventing condensed water from splashing onto the water pump 510 from both sides.

[0155] In some embodiments, as shown in FIG25 , the waterproof member 520 further includes a second escape portion 524 (second escape groove). The second escape portion 524 is disposed at the lower portion of the second body 528 and is located on the side of the second body 528 facing the third housing 13. The lower end of the second escape portion 524 communicates with the exterior of the waterproof member 520. A portion of the second water pipe 180 is positionally engaged within the second escape portion 524, and the second end of the second water pipe 180 extends through the second escape portion 524 to the exterior of the waterproof member 520.

[0156] In this way, it is convenient to connect the second water pipe 180 to the water pump 510 , and convenient to lead the second water pipe 180 from the inside of the water pump assembly 500 to the outside of the water pump assembly 500 .

[0157] For example, the second escape portion 524 may be configured as a second escape groove, and the second escape groove may be open downward, so that the second water pipe 180 may extend along the second escape groove to the outside of the water pump assembly 500 .

[0158] In some embodiments, as shown in Figures 23, 24, and 26, the water pump assembly 500 further includes a water pump box 530. The water pump box 530 is connected to the waterproof member 520 and together with the waterproof member 520 defines a receiving cavity 560. The water pump 510 is disposed in the receiving cavity 560, thereby facilitating improved sealing performance of the water pump assembly 500.

[0159] 25 and 26 , the water pump box 530 includes a second connection portion 531, and the waterproof member 520 further includes a third connection portion 525. The second connection portion 531 is fixedly connected to the third connection portion 525, thereby achieving a fixed connection between the water pump box 530 and the waterproof member 520.

[0160] For example, the second connection portion 531 includes one of a buckle or a slot, and the third connection portion 525 includes the other of the buckle or the slot. The buckle and the slot are snap-fitted together, thereby achieving a fixed connection between the water pump box 530 and the waterproof component 520.

[0161] For example, the second connection part 531 includes a first mounting hole, and the third connection part 525 includes a second mounting hole. In this way, the water pump box 530 and the waterproof part 520 can be fixedly connected by the fastener passing through the second mounting hole and then fixedly connected to the first mounting hole.

[0162] In some embodiments, as shown in Figures 24 and 26 , the water pump box 530 further includes a retaining member 532 (cooperating with a snap fastener). The retaining member 532 is located at the bottom of the water pump box 530 and corresponds to the position of the second escape portion 524. The retaining member 532 is configured to cooperate with the second escape portion 524 to secure and position the second water pipe 180, thereby improving the reliability of the installation of the second water pipe 180.

[0163] For example, referring to FIG. 26 , the retaining member 532 includes a first extension portion 533 . The first extension portion 533 extends toward the waterproof member 520 . The retaining member 532 also includes a second extension portion 534 , which is connected to the first extension portion 533 and extends in a second direction B. The retaining member 532 also includes a third extension portion 535 , which is connected to the second extension portion 534 and extends away from the waterproof member 520 . The second water pipe 180 is disposed within the retaining opening formed by the first extension portion 533 , the second extension portion 534 , and the third extension portion 535 , thereby improving the reliability of the installation of the second water pipe 180 .

[0164] In some embodiments, as shown in Figures 23 and 24, the window air conditioner 100 further includes a mounting base 540. The mounting base 540 is disposed between the water pump assembly 500 and the third housing 13 and is fixedly connected to the water pump assembly 500 and the third housing 13, respectively. Thus, the water pump assembly 500 is fixedly connected to the third housing 13 via the mounting base 540, which helps to improve the strength of the connection between the water pump assembly 500 and the third housing 13, thereby improving the reliability of the fixed connection between the water pump assembly 500 and the third housing 13.

[0165] For example, the mounting base 540 includes a third mounting hole, and the third shell 13 includes a fourth mounting hole. The mounting base 540 can be fixedly connected to the third shell 13 by passing a fastener (such as a screw) through the fourth mounting hole and then fixedly connected to the third mounting hole.

[0166] For example, the waterproof component 520 also includes a fifth mounting hole. In this way, after the fastener passes through the fifth mounting hole and the fourth mounting hole, it is fixedly connected to the third mounting hole, thereby fixing the waterproof component 520, the mounting seat 540 and the third shell 13.

[0167] 24 , the window air conditioner 100 further includes a buffer 550. The buffer 550 is disposed between the mounting base 540 and the water pump assembly 500, and the buffer 550 abuts against the mounting base 540 and the water pump assembly 500, respectively.

[0168] It is understood that the buffer member 550 can absorb the vibration generated during the operation of the water pump assembly 500, thereby reducing the noise generated during the operation of the window air conditioner 100.
