[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, the relative positions of the indoor unit and the outdoor unit of some window air conditioners are fixed, and the position of the indoor unit is low, so that the position of the air outlet located indoors is low, thereby affecting the cooling effect of the window air conditioner.

[0055] To solve the above technical problems, 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, thereby facilitating user adjustment of the height of the air outlet of the indoor unit as needed, thereby improving the cooling effect of the window air conditioner.

[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 the first direction A (i.e., the first predetermined direction), the left and right direction of the window air conditioner 100 is defined as the second direction B (i.e., the third predetermined direction), and the up and down direction (i.e., the height direction) of the indoor unit 1 is defined as the third direction C (i.e., the 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 191 of the outdoor unit 1 and to deliver the outdoor air, after heat exchange with the first heat exchanger 102, through a first air outlet 192 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 191 and a first air outlet 192 are formed in the first housing 11 and communicate with the first passage.

[0065] For example, the first air outlet 192 is located on a side of the first shell 11 away from the indoor unit 2 , so that outdoor air enters the first shell 11 from the first air inlet 191 and is then discharged from the first air outlet 192 .

[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 (pressure reducer) 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 193 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 194 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 193 and a second air outlet 194 (air outlet) are formed in the second housing 12 and communicate with the second passage. The second air outlet 194 is located on a side of the second housing 12 away from the outdoor unit 1. Indoor air enters the second housing 12 through the second air inlet 193 and is then discharged into the room through the second air outlet 194.

[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 predetermined direction). 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 194, 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 may be extended 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] For example, referring to FIG. 5 , the window-type air conditioner 100 further includes a limiting portion 140 , which is configured to limit the second housing 12 when the second housing 12 is located at the first position, so as to keep the second housing 12 at the first position.

[0087] In some embodiments, the second housing 12 includes a second bracket 121 and a first plate 122 (back plate). The first plate 122 is a side plate of the second housing 12 adjacent to the first housing 11. The first plate 122 is slidably connected to the third housing 13 and fixedly connected to the second bracket 121, thereby enabling the second housing 12 to move relative to the third housing 13 in the third direction C.

[0088] The second housing 12 further includes a first accommodation space. The first plate 122 and the second bracket 121 together define the first accommodation space. The second fan 106 and the second heat exchanger 104 are located in the first accommodation space.

[0089] In some embodiments, as shown in FIG6 , the second housing 12 further includes a first opening 125 (opening slot). The first opening 125 is provided in the first plate 122 and extends along the third direction C. The first pipe 41 is connected to the second pipe 42 through the first opening 125. When the second housing 12 moves relative to the third housing 13, the first pipe 41 moves along the third direction C relative to the first opening 125.

[0090] 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.

[0091] 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.

[0092] In some embodiments, as shown in Figure 3, the first end of the first pipeline 41 is fixed relative to the second bracket 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.

[0093] In some embodiments, as shown in Figures 7 to 9, the window air conditioner 100 further includes at least one first sliding assembly 910. The first sliding assembly 910 is fixedly connected to the third housing 13 and the first plate 122, respectively, so that the first plate 122 can slide relative to the third housing 13 along the third direction C through the first sliding assembly 910.

[0094] In some embodiments, as shown in Figures 7 to 9, the first sliding assembly 910 includes a first sliding portion 911 and a second sliding portion 912. The first sliding portion 911 is fixedly connected to the first plate 122, and the second sliding portion 912 is fixedly connected to the third housing 13. The first sliding portion 911 and the second sliding portion 912 are slidably connected, so that the first plate 122 can slide relative to the third housing 13 along the third direction C via the first sliding assembly 910, thereby increasing the height of the air outlet of the indoor unit 2 and improving the cooling effect of the window air conditioner 100.

[0095] For example, one of the first sliding portion 911 and the second sliding portion 912 is a slide rail, and the other of the first sliding portion 911 and the second sliding portion 912 is a slide groove. The slide rail and the slide groove extend along the third direction C, and the slide rail cooperates with the slide groove and can slide in the slide groove.

[0096] In some embodiments, as shown in FIG10 , one of the first sliding portion 911 and the second sliding portion 912 is a guide sleeve 915, and the other of the first sliding portion 911 and the second sliding portion 912 is a guide post 914. The guide sleeve 915 and the guide post 914 extend along the third direction C, the guide sleeve 915 cooperates with the guide post 914, and the guide post 914 can move along the third direction C relative to the guide sleeve 915.

[0097] For example, referring to FIG. 10 , the first sliding portion 911 is a guide post 914 , and the second sliding portion 912 is a guide sleeve 915 .

[0098] In some embodiments, as shown in FIG11 , the second housing 12 further includes a first escape portion 127 (a guide groove). The first escape portion 127 is disposed on a side of the first plate 122 facing the first housing 11 and is open toward the first housing 11. The first escape portion 127 extends along the third direction C, and the guide post 914 is disposed in the first escape portion 127. For example, the first escape portion 127 is a escape groove.

[0099] It can be understood that by avoiding the guide column 914 through the first avoiding portion 127, the space between the second shell 12 and the third shell 13 can be saved, which is conducive to reducing the size of the window air conditioner 100 in the first direction A.

[0100] In some embodiments, as shown in FIG11 , the first sliding assembly 910 further includes two stoppers 917 spaced apart along the third direction C and fixedly connected to the third housing 13. The two ends of the guide post 914 are respectively disposed in the two stoppers 917. The stoppers 917 are configured to restrict further movement of the second housing 12 when the second housing 12 moves along the third direction C to the first position or the second position. This prevents the first sliding portion 911 from disengaging from the second sliding portion 912, thereby improving the stability and reliability of the movement of the second housing 12 relative to the third housing 13.

[0101] In some embodiments, the first sliding assembly 910 further includes a fifth sliding portion 913, which is disposed between the first sliding portion 911 and the second sliding portion 912. The fifth sliding portion 913 is slidably connected to the first sliding portion 911 and the second sliding portion 912, respectively, thereby enabling the second sliding portion 912 to slide relative to the first sliding portion 911, thereby facilitating improved smoothness and stability of the sliding between the second sliding portion 912 and the first sliding portion 911.

[0102] For example, the first sliding portion 911 is a sliding rail or a sliding groove, and the surface of the fifth sliding portion 913 facing the first sliding portion 911 is configured as the other of the sliding rail or the sliding groove. The sliding rail cooperates with the sliding groove and is slidable in the sliding groove.

[0103] For example, the second sliding portion 912 is a slide rail or a slide groove, and the surface of the fifth sliding portion 913 facing the second sliding portion 912 is configured as the other of the slide rail and the slide groove. The slide rail cooperates with the slide groove and is slidable in the slide groove.

[0104] In some embodiments, the second housing 12 is made of plastic, which helps reduce the weight of the second housing 12 and facilitates the user to lift the indoor unit 2. In addition, the manufacturing process of plastic parts is simple, which helps improve production efficiency.

[0105] In some embodiments, as shown in FIG. 7 , the third housing 13 includes a third sub-housing 131 (first bridge section). The third 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 .

[0106] The third housing 13 further includes a fourth sub-housing 132 (second bridge section), which is located on a side of the second housing 12 close to the first housing 11 . The first plate 122 is slidably connected to the fourth sub-housing 132 via a first sliding assembly 910 .

[0107] The fourth sub-housing 132 is disposed inside the third sub-housing 131 and is movable relative to the third sub-housing 131. For example, the fourth sub-housing 132 can move relative to the third sub-housing 131 in the 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 use with windows or walls of varying thicknesses, thereby improving the adaptability of the window air conditioner 100.

[0108] 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.

[0109] In some embodiments, the first end of the second pipeline 42 is fixed relative to the third sub-shell 131 (ie, 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, which facilitates the arrangement of the second pipeline 42 .

[0110] For example, referring to FIG. 5 , the third housing 13 further includes a guide portion 139 , which is fixedly connected to the third sub-housing 131 . The first end of the second pipeline 42 is disposed in the guide portion 139 , thereby facilitating the arrangement of the second pipeline 42 .

[0111] It can be understood that since the third sub-shell 131 is fixedly connected to the first shell 11 and the third sub-shell 131 is slidingly connected to the fourth 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 fourth 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 12 and 13, the window air conditioner 100 further includes a second sliding assembly 920. The second sliding assembly 920 is disposed between the third sub-housing 131 and the fourth sub-housing 132 and is fixedly connected to the third sub-housing 131 and the fourth sub-housing 132, respectively. In this way, the third sub-housing 131 is slidably connected to the fourth sub-housing 132 via the second sliding assembly 920.

[0113] For example, the second sliding assembly 920 includes a third sliding portion 921 , which is fixedly connected to the third sub-housing 131 and located on a side (eg, inner side) of the third sub-housing 131 facing the fourth sub-housing 132 .

[0114] For example, the second sliding assembly 920 further includes a fourth sliding portion 922, which is fixedly connected to the fourth sub-housing 132 and is located on a side (e.g., an outer side) of the fourth sub-housing 132 that faces the third sub-housing 131. The third sliding portion 921 is slidably connected to the fourth sliding portion 922, thereby achieving a sliding connection between the third sub-housing 131 and the fourth sub-housing 132.

[0115] For example, one of the third sliding portion 921 and the fourth sliding portion 922 is a slide rail, and the other of the third sliding portion 921 and the fourth sliding portion 922 is a slide groove. The slide rail matches the slide groove and can slide in the slide groove.

[0116] In some embodiments, the second sliding assembly 920 has the same configuration as the first sliding assembly 910 .

[0117] In some embodiments, as shown in FIG7 , the third housing 13 further includes a first extension portion 135 (first plate), which is fixedly connected to the third sub-housing 131 and is located on a side of the third sub-housing 131 that is close to the second housing 12. For example, a first end (upper end) of the first extension portion 135 along the third direction C is connected to an end of the third sub-housing 131 that is close to the second housing 12, and a second end of the first extension portion 135 along the third direction C is located below the first end.

[0118] The first plate 122 is positioned adjacent to and opposite the first extension 135, and together with the first extension 135, defines a second accommodation space. The first sliding assembly 910 is disposed within the second accommodation space. For example, the first sliding portion 13 is fixedly connected to the first plate 122, and the second sliding portion 912 is fixedly connected to the first extension 135. This allows the first plate 122 and the first extension 135 to be slidably connected, thereby adjusting the air outlet height of the indoor unit 2 and improving the cooling effect of the window air conditioner 100.

[0119] 6 and 7 , the second housing 12 further includes two receiving portions 1221 , which are oppositely disposed on both sides of the first plate 122 along the second direction B. The receiving portions 1221 extend along the third direction C.

[0120] The third housing 13 further includes two first flanged portions 1351, which are disposed on opposite sides of the first extending portion 135 along the second direction B and extend toward the second housing 12. The two first flanged portions 1351 correspond to the two receiving portions 1221. At least a portion of the first flanged portions 1351 is disposed within the corresponding receiving portion 1221, thereby defining a second receiving space together with the receiving portion 1221.

[0121] For example, the accommodating portion 1221 is configured as a groove, and the groove is open toward the first flange portion 1351. At least a portion of the first flange portion 1351 is located in the groove, and together with the groove, defines a second accommodating space.

[0122] In some embodiments, as shown in FIG7 , the third housing 13 further includes a second extension 134 (a hanging plate), which is fixedly connected to the third sub-housing 131 and is located on a side of the third sub-housing 131 that is close to the second housing 12. For example, a first end (e.g., a lower end) of the second extension 134 along the third direction C is connected to an end of the third sub-housing 131 that is close to the second housing 12, and a second end of the second extension 134 along the third direction C is located above the first end.

[0123] For example, the first sliding portion 13 is fixedly connected to the first plate 122, the second sliding portion 912 is fixedly connected to the second extension portion 134, and the second extension portion 134 is fixedly connected to the first extension portion 135, so that the first plate 122 and the second extension portion 134 are slidingly connected, thereby adjusting the air outlet height of the indoor unit 2 and improving the cooling effect of the window air conditioner 100.

[0124] In some embodiments, at least one first sliding component 910 includes two first sliding components 910, and the two first sliding components 910 are respectively arranged on both sides of the second shell 12 along the second direction B. This is beneficial to the reliability and smoothness of the movement of the second shell 12 relative to the third shell 13 along the third direction C.

[0125] 1 , the indoor unit 2 further includes two lifting portions 128 . The two lifting portions 128 are disposed on both sides of the second housing 12 along the second direction B, so that the user can reach into the lifting portions 128 to adjust the height of the indoor unit 2 .

[0126] In some embodiments, as shown in FIG7 , the width of the third sub-housing 131 is greater than the width of the fourth sub-housing 132 along the second direction B. The fourth sub-housing 132 is disposed inside the third sub-housing 131 and is movable relative to the third sub-housing 131. At least a portion of the third sub-housing 131 and at least a portion of the fourth sub-housing 132 together constitute the bottom wall and side walls (e.g., two side walls along the second direction B) of the third housing 13.

[0127] In some embodiments, as shown in FIG14 , the third sub-housing 131 includes a first connecting portion 1311 (first plate portion) and a second connecting portion 1312 (first bridge housing portion). The first connecting portion 1311 is located on a side of the second connecting portion 1312 that is closer to the first housing 11 and is connected to the second connecting portion 1312. For example, a first end (e.g., an upper end) of the first connecting portion 1311 is connected to an end of the second connecting portion 1312 that is closer to the first housing 11, and the second end of the first connecting portion 1311 is located below the first end.

[0128] For example, the second connection portion 1312 is bent relative to the first connection portion 1311 .

[0129] In some embodiments, as shown in Figures 14 and 15, the fourth sub-housing 132 includes a third connecting portion 1321 (second first plate portion) and a fourth connecting portion 1322 (second bridge housing portion). The third connecting portion 1321 is located on a side of the fourth connecting portion 1322 that is closer to the second housing 12 and is connected to the fourth connecting portion 1322. For example, a first end (e.g., an upper end) of the third connecting portion 1321 is connected to an end of the fourth connecting portion 1322 that is closer to the first housing 11, and a second end of the third connecting portion 1321 is located below the first end.

[0130] For example, the fourth connection portion 1322 is bent relative to the third connection portion 1321 .

[0131] In some embodiments, the third connection portion 1321 includes the first extension portion 135 and two first flange portions 1351 described above.

[0132] In some embodiments, as shown in FIG14 , the width of the second connecting portion 1312 is greater than the width of the fourth connecting portion 1322 along the second direction B. The fourth connecting portion 1322 is disposed inside the second connecting portion 1312 and is movable relative to the second connecting portion 1312. The second connecting portion 1312 and the fourth connecting portion 1322 together constitute the bottom wall and side walls of the third housing 13. This facilitates movement of the fourth sub-housing 132 relative to the third sub-housing 131, thereby facilitating movement of the second housing 12 relative to the first housing 11 along 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.

[0133] 14 , the fourth connection portion 1322 includes a fourth flange portion 1323 and a second body 1324. The fourth flange portion 1323 is disposed on one side of the second body 1324 along the second direction B and connected to the second body 1324. The fourth flange portion 1323 is folded upward.

[0134] For example, the second sliding assembly 920 is disposed on a side of the fourth flange portion 1323 away from the second body 1324 and is fixedly connected to the fourth flange portion 1323. For example, the fourth sliding portion 921 is fixedly connected to the fourth flange portion 1323.

[0135] In some embodiments, as shown in Figures 14 and 15, the second connecting portion 1312 includes a fifth flange portion 1313 and a first body 1314. The fifth flange portion 1313 is disposed on one side of the first body 1314 along the second direction B and is connected to the first body 1314. The fifth flange portion 1313 is located on a side of the fourth flange portion 1323 away from the second body 1324 and is spaced a predetermined distance from the fourth flange portion 1323.

[0136] For example, the second sliding assembly 920 is disposed between the fourth flange portion 1323 and the fifth flange portion 1313 and is fixedly connected to the fourth flange portion 1323 and the fifth flange portion 1313 respectively, so that the fourth flange portion 1323 can slide relative to the fifth flange portion 1313 along the first direction A.

[0137] For example, the fourth sliding portion 921 is fixedly connected to the fourth flange portion 1323, and the fifth sliding portion 922 is fixedly connected to the fifth flange portion 1313, so that the fourth flange portion 1323 can slide relative to the fifth flange portion 1313 along the first direction A, thereby facilitating improving the stability of the second shell 12 moving relative to the first shell 11 along the first direction A.

[0138] In some embodiments, as shown in Figures 16 and 17, the third shell 13 also includes a first reinforcement portion 136 (reinforcement plate), which is arranged on the side of the third connection portion 1321 facing the second shell 12 and is fixedly connected to the third connection portion 1321, thereby facilitating improving the structural strength of the third connection portion 1321.

[0139] For example, the first reinforcement portion 136 and the third connection portion 1321 are welded and fixed, thereby improving the reliability of the connection between the first reinforcement portion 136 and the third connection portion 1321. For example, the first reinforcement portion 136 and the third connection portion 1321 can also be fixedly connected by fasteners such as screws, which is not limited in this disclosure.

[0140] In some embodiments, the third housing 13 further includes two third flanged portions 1361. The two third flanged portions 1361 are disposed on either side of the first reinforcement portion 136 along the second direction B and extend toward the second housing 12. The two third flanged portions 1361 are located between the two first flanged portions 1351 and correspondingly mate with the two first flanged portions 1351, thereby further improving the connection strength between the third connecting portion 1321 and the first reinforcement portion 136.

[0141] In some embodiments, as shown in FIG. 5 , the first sliding assembly 910 is fixedly connected to the third flange portion 1361 , thereby facilitating improved stability of the second housing 12 sliding relative to the third housing 13 .

[0142] In some embodiments, as shown in Figures 18 and 19, the third housing 13 further includes a fifth sub-housing 133 (connecting housing), which is disposed on the top and sides of the first connecting portion 1311 and the third connecting portion 1321 and is fixedly connected to the fourth sub-housing 132. The fifth sub-housing 133 constitutes the top wall and side walls of the third housing 13.

[0143] For example, along the second direction B, the width of the fifth sub-housing 133 is greater than the width of the third connecting portion 1321, and the third connecting portion 1321 is located inside the fifth sub-housing 133. In this way, the fifth sub-housing 133 covers the first connecting portion 1311 and the third connecting portion 1321, thereby preventing rainwater from entering the third housing 13 and causing short circuits or corrosion of components inside the third housing 13.

[0144] In some embodiments, as shown in FIG19 , the fifth sub-housing 133 includes a fifth connecting portion 1331 (a first plate segment) and two sixth connecting portions 1332 (a second plate segment), wherein the two sixth connecting portions 1332 are disposed on both sides of the fifth connecting portion 1331 along the second direction B and connected to the fifth connecting portion 1331. For example, the first ends (e.g., the upper ends) of the two sixth connecting portions 1332 are connected to both ends of the fifth connecting portion 1331 along the second direction B, and the second ends of the two sixth connecting portions 1332 are located below the first ends of the two sixth connecting portions 1332.

[0145] The fifth connection portion 1331 is located above the first connection portion 1311 , and the two sixth connection portions 1332 are located on both sides of the first connection portion 1311 along the second direction B.

[0146] In some embodiments, the fifth sub-housing 133 further includes two second flanges 1333 (connecting flanges). The two second flanges 1333 correspond to the two sixth connecting portions 1332 and are respectively connected to the second ends of the two sixth connecting portions 1332. The two second flanges 1333 are arranged opposite each other and extend toward each other. The second flanges 1333 are fixedly connected to the bottom wall of the third sub-housing 131, thereby achieving a fixed connection between the fifth sub-housing 133 and the third sub-housing 131.

[0147] For example, the second flange portion 1333 is fixedly connected to the first connection portion 1311 by fasteners such as screws, thereby achieving a fixed connection between the fifth sub-housing 133 and the third sub-housing 131 , which is beneficial to improving the reliability of the third housing 13 .

[0148] In some embodiments, as shown in FIG1 , the first housing 11 further includes a first sub-housing 111, which is fixedly connected to the third sub-housing 131. The first sub-housing 111 is disposed outside components such as the first fan 105 and the first heat exchanger 102 to protect them.

[0149] In some embodiments, as shown in FIG18 , the first housing 11 further includes a first base 112, which is located below the first sub-housing 111. The first base 112 is fixedly connected to the third sub-housing 131 and the first sub-housing 111. Components such as the first fan 105 and the first heat exchanger 102 are disposed on the first base 112.

[0150] For example, the first base 112 is fixedly connected to the third sub-housing 131 and the first sub-housing 111 respectively through fasteners such as screws.

[0151] In some embodiments, as shown in Figures 1 and 20, the second housing 12 further includes a second sub-housing 124, which is fixedly connected to the fourth sub-housing 132. The second sub-housing 124 is disposed outside components such as the second fan 106 and the second heat exchanger 104 to protect the second fan 106 and the second heat exchanger 104. For example, the second sub-housing 124 constitutes the top wall and side walls of the second housing 12 (such as the two side walls of the second housing 12 in the second direction B) and is fixedly connected to the first plate 122.

[0152] In some embodiments, as shown in FIG18 , the second housing 12 further includes a second base 123. The second base 123 is located below the second sub-housing 124 and is fixedly connected to the second sub-housing 124. The second base 123 extends horizontally. For example, the second fan 106 and the second heat exchanger 104 are fixed to the second base 123.

[0153] In some embodiments, as shown in FIG1 , the indoor unit 2 further includes a filter 25 (filter screen). The filter 25 is disposed on the second housing 12 and covers the second air inlet 193. The filter 25 is configured to prevent dust and other debris in the air from entering the interior of the indoor unit 2 through the second air inlet 193, thereby improving the cooling or heating efficiency of the window air conditioner 100.

[0154] 20 , the second housing 12 further includes a mounting portion 126 (filter element mounting bracket). The mounting portion 126 is disposed on a side of the second sub-housing 124 away from the first housing 11 and is configured to mount the filter element 25 .

[0155] In some embodiments, as shown in Figures 18 and 21, the window air conditioner 100 further includes an electrical box 400, a first portion of which is disposed within the third housing 13. A second portion of the electrical box 400 is disposed within the first housing 11, near the first fan 105. The electrical box 400 is disposed near the top of the first housing 11 and the third housing 13. The electrical box 400 is electrically connected to the compressor 101, the first fan 105, and the second fan 106, respectively, and is configured to supply power to the compressor 101, the first fan 105, and the second fan 106.

[0156] It is understandable that by arranging the electrical box 400 close to the top of the first shell 11 and the third shell 13, the electrical box 400 can be prevented from contacting rainwater or condensation water, thereby facilitating improving the working stability of the electrical box 400.

[0157] In some embodiments, the third housing 13 further includes a third accommodation space. The fifth sub-housing 133 and the fourth sub-housing 132 together define the third accommodation space, and the first portion of the electrical box 400 is disposed in the accommodation space.

[0158] In some embodiments, as shown in FIG18 , the first housing 11 further includes a first bracket 113 (motor bracket), which is disposed on the first base 112 and located within the first sub-housing 111. The first fan 105 is disposed in the first bracket 113 and is fixedly connected to the first bracket 113. The first heat exchanger is disposed opposite the first bracket 113. The second portion of the electrical box 400 is located within the first housing 11 and is fixedly connected to the first bracket 113, thereby facilitating improved connection strength between the electrical box 400 and the first housing 11.

[0159] For example, the first bracket 113 includes a third body and an air guide ring, which is disposed on the third body. The first fan 105 is disposed in the air guide ring. The air guide ring includes an air guide portion configured to guide the airflow passing therethrough.

[0160] In some embodiments, as shown in FIG. 21 , the electrical appliance box 400 includes a first box body 410 and a first cover 420 . The first cover 420 is disposed on the first box body 410 , and a fourth accommodation space is defined between the first box body 410 and the first cover 420 .

[0161] For example, a portion of the first cover 420 is located inside the first housing 11 and is fixedly connected to the first bracket 113 .

[0162] In some embodiments, as shown in FIG21 , the first cover 420 includes a plurality of first positioning portions 421 (first mounting legs) extending horizontally and fixedly connected to the first bracket 113 , thereby achieving a fixed connection between the first cover 420 and the first bracket 113 .

[0163] For example, any one of the plurality of first positioning portions 421 includes a fifth hole, and the first bracket 113 includes a plurality of sixth holes. The plurality of fifth holes corresponds to the plurality of sixth holes, so that the first positioning portion 421 can be fixedly connected to the first bracket 113 by fasteners such as screws passing through the fifth holes and the corresponding sixth holes, thereby improving the connection strength between the first cover 420 and the first bracket 113.

[0164] In some embodiments, as shown in FIG22 , the first housing 410 includes a second positioning portion 413 (second mounting leg). The second positioning portion 413 extends along a third direction C (e.g., downwardly) and is fixedly connected to the first housing 11, thereby achieving a fixed connection between the first housing 410 and the first housing 11.

[0165] For example, the second positioning portion 413 includes a seventh hole that extends through the second positioning portion 413 along the first direction A. The first housing 11 includes an eighth hole that corresponds to the position of the seventh hole. Thus, by using fasteners such as screws, the seventh and eighth holes are provided along the first direction A, thereby securely connecting the second positioning portion 413 to the first housing 11, thereby improving the connection strength between the first housing 410 and the first housing 11.

[0166] In some embodiments, as shown in Figures 21 and 22, the electrical box 400 further includes a circuit board 430, which is disposed within the fourth storage space 401. The circuit board 430 is electrically connected to the compressor 101, the first fan 105, and the second fan 106. It will be appreciated that the first cover 420 covering the first box body 410 can prevent condensation or rainwater from splashing onto the circuit board 430 and causing damage to the circuit board.

[0167] In some embodiments, as shown in Figures 23 to 25, the first housing 410 includes a first sub-housing 411 and a second sub-housing 412. The second sub-housing 412 defines a second accommodating cavity 4120, which is open upward. The first sub-housing 411 is disposed within the second accommodating cavity 4120. A fourth accommodating space is defined between the first sub-housing 411 and the first cover 420, and the circuit board 430 is fixedly connected to the first sub-housing 411.

[0168] It can be understood that the second sub-box 412 can provide protection for the first sub-box 411 .

[0169] For example, the second sub-box body 412 is made of a fireproof material, thereby playing a fireproof role. For example, the second sub-box body 412 is a metal piece, thereby increasing the rigidity and strength of the second sub-box body 412, which is conducive to improving the protection effect of the second sub-box body 412 on the first sub-box body 411.

[0170] In some embodiments, the first sub-box 411 includes a plurality of first engaging portions, which are spaced apart from each other. The second sub-box 412 includes a plurality of second engaging portions, which correspond to the plurality of first engaging portions. The plurality of first engaging portions are respectively engaged with the plurality of second engaging portions, thereby securely connecting the first sub-box 411 and the second sub-box 412. This helps improve the reliability of the connection between the first sub-box 411 and the second sub-box 412, and helps improve the assembly efficiency of the window air conditioner 100.

[0171] For example, the first clamping portion is one of a buckle or a slot, and the second clamping portion is the other of the buckle or the slot. The buckle and the slot are engaged with each other, thereby achieving a fixed connection between the first sub-box body 411 and the second sub-box body 412.

[0172] 23 and 24 , the first cover 420 further includes a seventh connecting portion 422 extending horizontally and a ninth hole 4221 disposed in and passing through the seventh connecting portion 422 .

[0173] The first sub-box body 411 further includes an eighth connecting portion 4117. The eighth connecting portion 4117 extends horizontally. The first sub-box body 411 further includes a tenth hole 4118, which is disposed in the eighth connecting portion 4117. The tenth hole 4118 corresponds to the ninth hole 4221. Fasteners, such as screws, are inserted through the ninth hole 4221 and the tenth hole 4118 to securely connect the seventh connecting portion 422 to the eighth connecting portion 4117, thereby achieving a secure connection between the first cover 420 and the first sub-box body 411.

[0174] For example, the ninth hole 4221 is a screw hole and the tenth hole 4118 is a through hole. In this way, after the tenth hole 4118 is penetrated by a fastener, it is fixedly connected to the ninth hole 4221, thereby achieving a fixed connection between the first cover body 420 and the first sub-box body 411.

[0175] It can be understood that the first sub-box body 411 and the second sub-box body 412 are first fixedly connected by the snap-fitting engagement of the first snap-fitting portion and the second snap-fitting portion, and then the first cover body 420 is fixedly connected to the first sub-box body 411 by fasteners, so that the first cover body 420, the first sub-box body 411 and the second sub-box body 412 can be fixedly connected.

[0176] In some embodiments, as shown in Figures 23 and 25, the second sub-box body 412 further includes a ninth connecting portion 4125. The ninth connecting portion 4125 extends horizontally. The second sub-box body 412 further includes an eleventh hole 4126, which is disposed in and extends through the ninth connecting portion 4125. The positions of the eleventh hole 4126, the tenth hole 4118, and the ninth hole 4221 correspond to each other. The eleventh hole 4126, the tenth hole 4118, and the ninth hole 4221 are formed by fasteners, thereby securely connecting the second sub-box body 412, the first sub-box body 411, and the first cover body 420, thereby improving the connection strength between the first box body 410 and the first cover body 420.

[0177] For example, the ninth hole 4221 is a screw hole, and the eleventh hole 4126 and the tenth hole 4118 are through holes. In this way, after the eleventh hole 4126 and the tenth hole 4118 are penetrated by fasteners, they are fixedly connected to the ninth hole 4221, thereby realizing the fixed connection between the second sub-box body 412, the first sub-box body 411 and the first cover body 420.

[0178] In some embodiments, as shown in Figures 23 and 24, the first sub-box body 411 further includes a plurality of twelfth holes 4116. The plurality of twelfth holes 4116 correspond to the plurality of fifth holes. Thus, by fasteners penetrating the fifth holes, the twelfth holes 4116, and the sixth hole, the first cover body 420, the first sub-box body 411, and the first bracket 113 can be fixedly connected.

[0179] In some embodiments, as shown in FIG24 , the first sub-box 411 further includes a plurality of first heat dissipation holes 4114. As shown in FIG25 , the second sub-box 412 further includes a plurality of second heat dissipation holes 4123. The plurality of second heat dissipation holes 4123 are staggered with the plurality of first heat dissipation holes 4114, and heat dissipation channels are formed between the second heat dissipation holes 4123 and the first heat dissipation holes 4114, thereby improving the heat dissipation efficiency of the circuit board 430 and preventing rainwater from directly entering the electrical box 400 through the first heat dissipation holes 4114 and the second heat dissipation holes 4123.

[0180] For example, any plane parallel to the first direction A and the second direction B is defined as the first reference plane, and the multiple second heat dissipation holes 4123 and the multiple first heat dissipation holes 4114 are staggered, which means that the orthographic projection of the second heat dissipation holes 4123 on the first reference plane does not overlap with the orthographic projection of the first heat dissipation holes 4114 on the first reference plane.

[0181] It is understandable that when the window air conditioner 100 is running, the first fan will send air to the surface of the electrical box 400, causing negative pressure to be generated inside the electrical box 400. In this way, the high-temperature gas in the first sub-box body 411 can be discharged to the outside of the electrical box 400 after passing through the first heat dissipation hole 4114, the heat dissipation channel and the second heat dissipation hole 4123 under the action of negative pressure.

[0182] In some embodiments, as shown in FIG24 , the first sub-box 411 further includes a first bottom plate 4112. A plurality of first heat dissipation holes 4114 are formed in the first bottom plate 4112. The circuit board 430 corresponds to the positions of the plurality of first heat dissipation holes 4114, thereby improving the heat dissipation efficiency of the circuit board 430. The first sub-box 411 further includes a plurality of first side plates 4113. The plurality of first side plates 4113 are disposed around the first bottom plate 4112 and connected to the first bottom plate 4112.

[0183] In some embodiments, as shown in FIG25 , the second sub-box body 412 further includes a second bottom plate 4121, with a plurality of second heat dissipation holes 4123 formed in the second bottom plate 4121. The second sub-box body 412 further includes a plurality of second side plates 4122, which are disposed around and connected to the second bottom plate 4121. The plurality of second side plates 4122 correspond to the plurality of first side plates 4113, and the second bottom plate 4121 is disposed opposite the first bottom plate 4112.

[0184] In this way, by forming the first heat dissipation holes 4114 and the second heat dissipation holes 4123 at a lower position, water in the electrical box 400 can be discharged to the outside of the electrical box 400 from the first heat dissipation holes 4114 and the second heat dissipation holes 4123 under the action of gravity.

[0185] In some embodiments, the plurality of second heat dissipation holes 4123 are located in the middle of the second base plate 4121, and the orthographic projections of the plurality of first heat dissipation holes 4114 on the first reference plane surround the orthographic projections of the plurality of second heat dissipation holes 4123 on the first reference plane, thereby achieving the staggered arrangement of the plurality of second heat dissipation holes 4123 and the plurality of first heat dissipation holes 4114.

[0186] In some embodiments, the first heat dissipation hole 4114 is located in the middle of the first base plate 4112, and the orthographic projections of the multiple second heat dissipation holes 4123 on the first reference plane surround the orthographic projections of the multiple first heat dissipation holes 4114 on the first reference plane, thereby achieving the staggered arrangement of the multiple second heat dissipation holes 4123 and the multiple first heat dissipation holes 4114.

[0187] In some embodiments, as shown in Figures 23 and 24, the first sub-case 411 further includes a plurality of third heat dissipation holes 4115. The plurality of third heat dissipation holes 4115 are disposed in at least one of the plurality of first side panels 4113. The circuit board 430 can correspond to the positions of the plurality of third heat dissipation holes 4115, thereby facilitating improved heat dissipation efficiency of the circuit board 430.

[0188] As shown in Figures 23 and 25, the second sub-box body 412 also includes a plurality of fourth heat dissipation holes 4124, which are disposed in at least one second side panel 4122 corresponding to the at least one first side panel 4113. The plurality of fourth heat dissipation holes 4124 are offset from the plurality of third heat dissipation holes 4115, and a heat dissipation channel is formed between the plurality of third heat dissipation holes 4115 and the plurality of fourth heat dissipation holes 4124. This improves the heat dissipation efficiency of the circuit board 430 and prevents rainwater from directly entering the electrical box 400 through the third heat dissipation holes 4115 and the fourth heat dissipation holes 4124, thereby improving the waterproof performance of the electrical box 400.

[0189] For example, any plane parallel to the first direction A and the third direction C is defined as the second reference plane, and the plurality of fourth heat dissipation holes 4124 and the plurality of third heat dissipation holes 4115 are staggered, which means that the orthographic projections of the plurality of fourth heat dissipation holes 4124 on the second reference plane do not overlap with the orthographic projections of the plurality of third heat dissipation holes 4115 on the second reference plane.

[0190] For example, the plurality of third heat dissipation holes 4115 are disposed in one of the plurality of first side panels 4113. The third heat dissipation hole 4115 is disposed in the middle portion of the first side panel 4113. The plurality of fourth heat dissipation holes 4124 are disposed in the second side panel 4122 corresponding to the first side panel 4113, and the orthographic projections of the plurality of fourth heat dissipation holes 4124 on the second reference plane are located along the first direction A on both sides of the orthographic projections of the plurality of third heat dissipation holes 4115 on the second reference plane. This allows the plurality of third heat dissipation holes 4115 to be staggered with the plurality of fourth heat dissipation holes 4124.

[0191] In some embodiments, the first sub-box body 411 further includes a first water retaining portion, which is connected to the first side panel 4113 and is disposed near the third heat dissipation hole 4115. For example, the first water retaining portion is located on a side of the first side panel 4113 near the second side panel 4122 and extends toward the second side panel 4122. Thus, when rainwater splashes from the side of the electrical box 400 into the second sub-box body 412, the first water retaining portion blocks the splashing water droplets, thereby preventing water from entering the first sub-box body 411 through the third heat dissipation hole, thereby improving the waterproof performance of the electrical box 400.

[0192] In some embodiments, the circuit board 430 is electrically connected to the compressor 101, the first fan 105, and the second fan 106 through a wire. The first side panel 4113 includes at least one first wire outlet, and the second side panel 4122 includes at least one second wire outlet. The first wire outlet and the second wire outlet are staggered. The first end of the wire is connected to the circuit board 430, and the second end of the wire passes through the first wire outlet and the second wire outlet to be connected to the compressor 101, the first fan 105, or the second fan 106. In this way, rainwater can be prevented from entering the electrical box 400 through the first wire outlet and the second wire outlet, which is conducive to improving the waterproof performance of the electrical box 400.

[0193] For example, the orthographic projection of the first cable outlet on the second reference plane does not overlap with the orthographic projection of the second cable outlet on the second reference plane.

[0194] For example, the at least one first wire outlet includes a plurality of first wire outlets, and the at least one second wire outlet includes a plurality of second wire outlets, thereby facilitating electrical connection of the circuit board 430 to a plurality of devices via a plurality of wires. The orthographic projections of the plurality of first wire outlets on the second reference plane do not overlap with the orthographic projections of the plurality of second wire outlets on the second reference plane, thereby facilitating improved waterproof performance of the electrical box 400.

[0195] In some embodiments, the first sub-box body 411 also includes multiple second water retaining parts, which are respectively connected to the first side panel 4113 and the second side panel 4122, and are located below the first wire outlet and the second wire outlet, so that the bottom of the first wire outlet and the second wire outlet can be separated from the outside world, preventing splashing rainwater from entering the first wire outlet and the second wire outlet from the bottom side, which is beneficial to improve the waterproof performance of the electrical box 400.

[0196] The electrical box 400 also includes a radiator 440, a first end of the radiator 440 is connected to the circuit board 430, and a second end of the radiator 440 is located outside the fourth accommodation space and extends toward the first fan 105. In this way, the first fan 105 can take away the heat accumulated in the radiator 440, thereby helping to improve the heat dissipation performance of the radiator 440.

[0197] In some embodiments, the first box body 410 further includes a thirteenth hole 414 . The thirteenth hole 414 is disposed in the first sub-box body 411 and penetrates the first sub-box body 411 along the third direction C.

[0198] The heat sink 440 includes a heat dissipation substrate that abuts the circuit board 430 to absorb heat dissipated by the circuit board 430. The heat sink 440 also includes heat dissipation fins that extend through the thirteenth hole 414 to the exterior of the first sub-case 411. For example, a portion of the heat dissipation fins is located outside the first sub-case 411. The heat dissipation fins are configured to conduct heat from the heat dissipation substrate to the exterior of the first sub-case 411.

[0199] For example, the heat dissipation substrate is bonded to the control chip of the circuit board 430. It is understood that the control chip is the main heat source of the circuit board 430. Therefore, by bonding the heat dissipation substrate to the control module, the heat dissipated by the circuit board 430 can enter the heat dissipation fins through the heat dissipation substrate. The heat dissipation fins directly exchange heat with the outside air, thereby achieving cooling of the circuit board 430.

[0200] For example, the inner contour of the thirteenth hole 414 is adapted to the outer contour of the heat sink fin, and the heat sink fin cooperates with the thirteenth hole 414, so that the interior of the first sub-box body 411 is separated from the outside, thereby preventing splashing rainwater from entering the interior of the first sub-box body 411 through the thirteenth hole 414, which is beneficial to improving the waterproof performance of the electrical box 400.

[0201] In some embodiments, the first box body 410 further includes a third water retaining portion, which is disposed on the first sub-box body 411 and is disposed near the thirteenth hole 414. The third water retaining portion can prevent splashing rainwater from entering the thirteenth hole 414, thereby further improving the waterproof performance of the electrical box 400.

[0202] In some embodiments, as shown in FIG30 , the third housing 13 further includes a second reinforcement portion 137. The second reinforcement portion 137 is disposed between the fifth connection portion 1331 and the electrical box 400 and is fixedly connected to the electrical box 400, thereby protecting the electrical box 400 and improving the structural strength of the electrical box 400.

[0203] In some embodiments, as shown in FIG30 , the third housing 13 further includes a second plate 138 (shielding plate). The second plate 138 is disposed between the second reinforcing portion 137 and the electrical box 400 and is configured to prevent high-frequency electromagnetic fields from affecting the electrical box 400, thereby improving the operational stability of the electrical box 400. For example, the second plate is a shielding plate made of a material that can shield or block high-frequency electromagnetic fields.

[0204] In some embodiments, as shown in Figures 11 to 27, the window air conditioner 100 further includes a rolling assembly 500, which is located between the second housing 12 and the third housing 13. The first portion of the rolling assembly 500 is fixedly connected to one of the second housing 12 or the third housing 13, and the second portion of the rolling assembly 500 is rollable relative to the other of the second housing 12 or the third housing 13, thereby separating the second housing 12 and the third housing 13 by a predetermined distance and reducing the contact area between the second housing 12 and the third housing 13. In this way, the friction force when the second housing 12 moves relative to the third housing 13 can be reduced, which helps to improve the smoothness of the movement of the second housing 12.

[0205] 27 and 28 , the rolling assembly 500 includes a mounting box 510. The mounting box 510 is fixedly connected to one of the second housing 12 or the third housing 13.

[0206] The rolling assembly 500 further includes a rolling member 520 (roller), which is disposed within the mounting box 510 and is rollable relative to the mounting box 510. The rolling assembly 500 further includes a first hole 501, through which a portion of the rolling member 520 is exposed and located outside the mounting box 510. The exposed portion of the rolling member 520 abuts against the other of the second housing 12 or the third housing 13, allowing the rolling member 520 to roll relative to the other of the second housing 12 or the third housing 13.

[0207] In this way, the friction force when the second shell 12 moves relative to the third shell 13 can be reduced, which is conducive to improving the smoothness of the movement of the second shell 12.

[0208] For ease of description, the following describes the structure and function of the rolling assembly 500 by taking the example that the mounting box 510 is fixedly connected to the second housing 12 and the rolling member 520 is rollable relative to the third housing 13 .

[0209] In some embodiments, as shown in FIG29 , the installation box 510 includes a second box body 511 and a second cover 512. The second box body 511 is fixedly connected to the second cover 512. The installation box 510 also includes a first accommodating cavity 550, which is defined by the second box body 511 and the second cover 512. A rolling member 520 is disposed in the first accommodating cavity 550. The outer contour of the rolling member 520 matches the inner contour of the first accommodating cavity 550, so that the rolling member 520 can roll relative to the installation box 510.

[0210] For example, the mounting box 510 is located on a side of the first plate 122 away from the third housing 13 and is fixedly connected to the first plate 122. The second cover 512 is located between the second box 511 and the first plate 122. The rolling member 520 passes through the second cover 512 and the first plate 122 and abuts against the third housing 13, allowing the rolling member 520 to roll relative to the third housing 13. Thus, by locating the mounting box 510 on a side of the first plate 122 away from the third housing 13, the space between the second housing 12 and the third housing 13 can be avoided, thereby improving the neatness and compactness of the internal structure of the window air conditioner 100.

[0211] In some embodiments, the second box body 511 includes one of a buckle or a slot, and the second cover body 512 includes the other of the buckle or the slot. The buckle and the slot are snap-fitted together to provide a preliminary fixed connection between the second box body 511 and the second cover body 512, thereby facilitating improving the assembly efficiency of the window air conditioner 100.

[0212] In some embodiments, as shown in Figures 27 to 29, the rolling assembly 500 further includes a second hole 530, which is disposed in the second box body 511 and penetrates the second box body 511 along the thickness direction of the second box body 511 (such as the first direction A).

[0213] The rolling assembly 500 also includes a third hole 540, which is disposed in the second cover 512 and extends through the second cover 512 along the thickness direction of the second cover 512 (e.g., the first direction A). The position of the third hole 540 corresponds to the second hole 530. A fastener (e.g., a screw) is inserted through the second hole 530 and then connected to the third hole 540, thereby securely connecting the second box body 511 to the second cover 512. It will be appreciated that, in addition to the snap-fit ​​connection, the use of fasteners to securely connect the second box body 511 to the second cover 512 helps improve the reliability of the connection between the second box body 511 and the second cover 512.

[0214] In some embodiments, as shown in Figures 26 and 27 , the rolling assembly 500 further includes a third positioning portion 560 disposed on the second cover 512. The second housing 12 further includes a fourth positioning portion 1222 disposed on the first plate 122 and corresponding to the position of the third positioning portion 560. The third positioning portion 560 cooperates with the fourth positioning portion 1222 to facilitate the positioning and connection of the second cover 512 to the first plate 122, thereby improving the assembly efficiency of the window air conditioner 100.

[0215] For example, the third positioning portion 560 is one of the positioning hole and the positioning column, and the fourth positioning portion 1222 is the other of the positioning hole and the positioning column. The positioning column cooperates with the positioning hole and is limited in the positioning hole, thereby facilitating the positioning connection between the second cover body 512 and the first plate 122.

[0216] In some embodiments, as shown in FIG. 29 , the rolling element 520 includes a first rolling portion 521 (first roller) and two second rolling portions 522 (second rollers), and the two second rolling portions 522 are arranged on both sides of the first rolling portion 521 along the axial direction of the first rolling portion 521 .

[0217] The first accommodating chamber 550 includes a first sub-cavity 551. The first rolling portion 521 is disposed within the first sub-cavity 551 and is adapted to fit within the first sub-cavity 551. The first rolling portion 521 is radially larger than the second rolling portion 522, and a portion of the first rolling portion 521 is exposed through the first hole 501. The first accommodating chamber 550 also includes a second sub-cavity 552. Two second rolling portions 522 are disposed within each of the two second sub-cavities 552 and are adapted to fit within the second sub-cavities 552.

[0218] In this way, when the rolling element 520 rolls relative to the third housing 13 , the first rolling portion 521 rolls in the first sub-cavity 551 , and the second rolling portion 522 rolls in the second sub-cavity 552 , thereby facilitating improved stability of the rolling element 520 .

[0219] 27 , the rolling assembly 500 further includes a fourth avoidance portion 570 . The fourth avoidance portion 570 defines a second sub-cavity 552 and protrudes toward the third housing 13 . The fourth avoidance portion 570 is configured to avoid the second rolling portion 522 .

[0220] As shown in FIG26 , the second housing 12 further includes a second avoidance portion 1223 disposed in the first plate 122. The second avoidance portion 1223 is recessed toward the third housing 13 to avoid the fourth avoidance portion 570. For example, the second avoidance portion 1223 is a avoidance groove, and the fourth avoidance portion 570 is located in the avoidance groove.

[0221] In some embodiments, as shown in FIG26 , the second housing 12 further includes a fourth hole 1225. The fourth hole 1225 is disposed in the first plate 122 and extends through the first plate 122 along the thickness direction (e.g., the first direction A) of the first plate 122. Thus, by inserting a fastener such as a screw through the fourth hole 1225 and the second hole 530 and then securing it to the third hole 540, the rolling assembly 500 can be securely connected to the second housing 12.

[0222] The second housing 12 further includes a third relief portion 1224. A portion of the first plate 122 is recessed away from the third housing 13 to form the third relief portion 1224. The fourth hole 1225 is located in the third relief portion 1224, and the third relief portion 1224 is configured to avoid a fastener passing through the fourth hole 1225, thereby preventing the fastener from protruding from the first plate 122 and rubbing against the third housing 13.

[0223] In some embodiments, the mounting box 510 is fixedly connected to the third housing 13 (e.g., the third connecting portion 1321 of the fourth sub-housing 132), and the rolling element 520 is rollable relative to the second housing 12. It will be understood that regardless of whether the mounting box 510 is fixedly connected to the second housing 12 or the third housing 13, the structure and function of the rolling assembly 500 remain unchanged, and therefore, the above examples should not be considered as limitations of the present disclosure.
