[0101] In fresh air air conditioners, the fresh air system and the heat exchange system for indoor air heat exchange mostly work independently of each other. Fresh air and air-conditioned air are usually output into the room through different air outlets. Outdoor fresh air is output into the room through the second air outlet, and air-conditioned air is output into the room through the first air outlet. In conventional wall-mounted fresh air air conditioners, the second air outlet is usually distributed along the length of the casing together with the first air outlet. Since the first air outlet extends along the length of the casing, the opening size of the second air outlet is smaller, and the diffusion range of the outdoor fresh air in the room is smaller. The second air outlet is distributed along the length of the casing together with the first air outlet. The outdoor fresh air and air-conditioned air are discharged relatively independently, and the degree of mixing between the outdoor fresh air and air-conditioned air is low. When the temperature difference between the outdoor fresh air and the air-conditioned air is large, two airs of different temperatures blow toward the user, which can easily cause user discomfort and reduce the user experience.

[0102] The present disclosure provides a wall-mounted air-conditioning indoor unit that includes at least a casing 100 , a heat exchanger 400 , a heat exchange fan 300 , a fresh air module, and a fresh air component 500 .

[0103] As shown in Figures 1-3, the housing 100 is configured to form the overall appearance of the air conditioner indoor unit. The housing 100 has a top and a bottom. The top and bottom of the housing 100 are opposite ends, and the height of the housing 100 is measured from the top to the bottom of the housing 100. The left side of the housing 100 and the right side of the housing 100 are opposite ends, and the length of the housing 100 is measured from the left to the right. The front side of the housing 100 and the rear side of the housing 100 are opposite ends, and the thickness of the housing 100 is measured from the front to the rear. In actual use, the housing 100 is typically installed on the ceiling of a room or in an upper space within the room, with the rear side of the housing 100 facing the wall and the front side of the housing 100 facing the user.

[0104] As shown in Figure 5, a first inner cavity 104 is defined inside the casing 100, and the casing 100 includes a first air inlet 101 and a first air outlet 102. The first air inlet 101 and the first air outlet 102 are respectively connected to the first inner cavity 104. Indoor air is output to the room from the first air inlet 101 through the first inner cavity 104 and the first air outlet 102.

[0105] The first air inlet 101 is located at the top of the casing 100 and extends along the length of the casing 100 . An air inlet grille is provided at the first air inlet 101 to prevent dust or debris from entering the interior of the casing 100 through the first air inlet 101 .

[0106] The first air outlet 102 is located on the front side of the housing 100 and near the bottom of the housing 100. That is, the first air outlet 102 is located on the lower front side of the housing 100. The first air outlet 102 extends along the length of the housing 100. An air deflector 200 is provided at the first air outlet 102. The air deflector 200 is connected to the housing 100 in an openable and closable manner to open and close the first air outlet 102.

[0107] As shown in Figures 6 and 7, the heat exchanger 400 is installed in the housing 100 and located within the first inner cavity 104. The air within the first inner cavity 104 contacts the heat exchanger 400 and is heated by the heat exchanger 400 to form conditioned air, thereby meeting the user's cooling or heating needs. It should be noted that the heat exchanger 400 is located near the first air inlet 101. It should also be noted that the conditioned air can be cold air, hot air, or even air at room temperature.

[0108] As shown in Figures 6 and 7 , the heat exchange fan 300 is mounted on the housing 100 and located within the first inner cavity 104. The heat exchange fan 300 is also located below the heat exchanger 400. The axial direction of the heat exchange fan 300 extends along the length of the housing 100. The heat exchange fan 300 operates to draw indoor air into the first inner cavity 104 through the first air inlet 101. After heat exchange in the heat exchanger 400 to form conditioned air, the conditioned air flows into the room through the first air outlet 102. It should be noted that the heat exchange fan 300 is a cross-flow fan.

[0109] The fresh air module is configured to introduce outdoor fresh air into the room. The interior of the casing 100 is defined to have a second inner cavity 105 for installing the fresh air module. The second inner cavity 105 and the first inner cavity 104 are distributed along the length direction of the casing 100, so that the fresh air module and the heat exchanger 400 and / or the heat exchange fan 300 are distributed along the length direction of the casing 100.

[0110] It should be noted that the casing 100 includes a front side panel 110 and a rear shell 120. The front side panel 110 is located in front of the rear shell 120. The front side panel 110 and the rear shell 120 are arranged opposite to each other in the horizontal plane along the thickness direction of the casing 100. The first air inlet 101 and the first air outlet 102 are respectively arranged in the rear shell 120. The first inner cavity 104 and the second inner cavity 105 are located inside the rear shell 120. The heat exchanger 400, the heat exchange fan 300 and the fresh air module are respectively installed inside the rear shell 120. By designing the casing 100 as a split type, the installation and disassembly of the heat exchanger 400, the heat exchange fan 300 and the fresh air module can be facilitated.

[0111] As shown in Figures 7 and 13, a base 130 is provided in the rear shell 120, and the base 130 and the rear shell 120 together define a first inner cavity 104 and a second inner cavity 105; wherein the heat exchanger 400, the heat exchange fan 300 and the fresh air module are respectively installed on the base 130.

[0112] The fresh air module includes a fresh air volute 600 and a fresh air fan. The fresh air volute 600 and the heat exchange fan 300 are distributed along the length direction of the casing 100. A fresh air duct is defined in the fresh air volute 600. The fresh air fan is installed in the fresh air duct. The fresh air volute 600 is provided with a volute air inlet 602 and a volute air outlet 601. The volute air inlet 602 and the volute air outlet 601 are respectively connected to the fresh air duct, the volute air inlet 602 is connected to the outdoors, and the volute air outlet 601 is connected to the indoors; through the operation of the fresh air fan, the outdoor fresh air is introduced into the fresh air duct through the volute air inlet 602, and output to the indoors through the volute air outlet 601.

[0113] The housing 100 further includes a second air outlet 103 , which is connected to the volute air outlet 601 , so that the outdoor fresh air in the fresh air duct passes through the volute air outlet 601 and is output from the second air outlet 103 to the room.

[0114] As shown in Figures 10 and 11, the fresh air volute 600 includes a first volute 610, a second volute 620, and a fresh air housing 630. The first volute 610 and the second volute 620 are arranged opposite each other and together form a fresh air cavity, in which the fresh air fan is installed. The fresh air housing 630 and the second volute 620 are arranged opposite each other on the side facing away from the first volute 610 to together form a purification chamber. The fresh air cavity and the purification chamber together form a fresh air duct. By designing the fresh air volute 600 as a split type, the fresh air fan can be easily installed in the fresh air cavity.

[0115] The second volute 620 is provided with a fresh air grille 621, which is located at the connection between the purification chamber and the fresh air cavity so that the purification chamber and the fresh air cavity are interconnected. A purification module 700 is provided in the purification chamber, and the purification module 700 is configured to purify the outdoor fresh air. It should be noted that the volute air inlet 602 is opened in the purification chamber, and the volute air outlet 601 is opened in the fresh air cavity, so that the purification module 700 purifies the outdoor fresh air entering the purification chamber through the volute air inlet 602, and the air in the purification chamber that has been purified by the purification module 700 enters the fresh air cavity through the fresh air grille 621, and flows into the room through the volute air outlet 601 from the second air outlet 103.

[0116] The purification chamber is provided with a first socket so that the purification module 700 can be extended into the purification chamber through the first socket, thereby realizing the installation of the purification module 700. When the purification module 700 needs to be disassembled, the purification module 700 can be unplugged from the first socket. By detachably installing the purification module 700 in the purification chamber, it is convenient for the user to disassemble the purification module 700. The disassembly and installation method of the purification module 700 is simple and easy to operate.

[0117] As shown in Figure 5, the rear shell 120 also includes a second socket 107, which is arranged corresponding to the first socket. When the purification module 700 needs to be removed or installed, only the front side panel 110 needs to be removed to allow the purification module 700 to be inserted into the purification room from the second socket 107 through the first socket, or the purification module 700 can be left from the purification room from the first socket through the second socket 107, thereby realizing the installation and disassembly of the purification module 700 without disassembling the fresh air volute 600.

[0118] The fresh air fan is a centrifugal fan, which is configured to introduce indoor fresh air into the room; the fresh air fan is installed in the fresh air cavity, and through the operation of the fresh air fan, the outdoor fresh air is introduced into the purification room through the volute air inlet 602, and after purification by the purification module 700, it enters the fresh air cavity, passes through the volute air outlet 601, and flows into the room from the second air outlet 103.

[0119] It should be noted that the axial direction of the fresh air fan is arranged along the length direction of the housing 100, causing the outdoor fresh air to flow in a direction intersecting the length direction of the housing 100 after passing through the fresh air fan. The opening direction of the volute air outlet 601 is generally designed to intersect the length direction of the housing 100, the purpose of which is to facilitate the outdoor fresh air to flow out of the fresh air chamber through the volute air outlet 601.

[0120] As shown in FIG2 and FIG3, the second air outlet 103 extends along the length direction of the housing 100 so that the second air outlet 103 is in a strip shape, thereby increasing the diffusion range of the outdoor fresh air in the room and increasing the uniformity of the outdoor fresh air output to the room.

[0121] Since the second inner cavity 105 and the first inner cavity 104 are distributed along the length of the casing 100, the fresh air volute 600 is located at one end of the length direction of the casing 100, and the second air outlet 103 extends along the length direction of the casing 100, which makes it difficult to directly set the volute air outlet 601 of the fresh air volute 600 to correspond to the second air outlet 103. Therefore, in this embodiment, a fresh air piece 500 is set, and an air outlet duct is formed by utilizing the internal limitation of the fresh air piece 500, so that the air outlet duct connects the fresh air duct inside the fresh air volute 600 and the second air outlet 103, so that the volute air outlet 601 is connected to the second air outlet 103 through the interior of the fresh air piece 500, and then the outdoor fresh air in the fresh air volute 600 is output to the room from the second air outlet 103 through the fresh air piece 500.

[0122] For example, as shown in Figures 8 and 9, one end of the fresh air piece 500 is connected to the fresh air volute 600, and the other end of the fresh air piece 500 extends along the length direction of the casing 100 in a direction away from the fresh air volute 600; an air outlet duct is defined inside the fresh air piece 500, and the air outlet duct extends along the length direction of the casing 100 and is connected to the fresh air duct inside the fresh air volute 600.

[0123] The fresh air component 500 is provided with a fourth air outlet 501 extending along the length direction of the casing 100. The fourth air outlet 501 is connected to the air outlet duct, and the fourth air outlet 501 is arranged corresponding to the second air outlet 103, so that the air outlet duct is connected to the second air outlet 103 through the fourth air outlet 501, so that the outdoor fresh air in the air outlet duct can be output to the room through the second air outlet 103.

[0124] As shown in Figure 13, a connecting port 503 is provided at one end of the fresh air piece 500 connected to the fresh air volute 600. The connecting port 503 is arranged corresponding to the volute air outlet 601 to connect the air outlet duct inside the fresh air piece 500 with the fresh air duct inside the fresh air volute 600.

[0125] The fresh air component 500 is usually arranged in the casing 100 to maintain the overall aesthetics of the air conditioner indoor unit; and the fresh air component 500 is located outside the first inner cavity 104 to avoid affecting the heat exchange of the heat exchanger 400 as much as possible.

[0126] In some embodiments, the fresh air member 500 is installed between the front side panel 110 and the rear housing 120. The front side panel 110 and the rear housing 120 are arranged opposite each other in a horizontal plane and together define a receiving chamber. The receiving chamber is located in front of the first inner cavity 104 and the second inner cavity 105. The fresh air member 500 is located within the receiving chamber. Since the fresh air member 500 is installed between the front side panel 110 and the rear housing 120, it can be seen that the fresh air member 500 is located outside the rear housing 120, which also means that the fresh air member 500 is located outside the second inner cavity 105.

[0127] Since the fresh air volute 600 is located in the second inner cavity 105, and the fresh air piece 500 is arranged on the outside of the second inner cavity 105 (that is, the fresh air piece 500 is arranged in the accommodating cavity jointly defined by the front side plate 110 and the rear shell 120), in order to facilitate the connection between the fresh air volute 600 and the fresh air piece 500, as shown in Figure 5, the rear shell 120 is provided with a through-out portion 106, and the volute air outlet 601 and the connecting port 503 are respectively arranged corresponding to the through-out portion 106, so that the outdoor fresh air in the fresh air volute 600 can pass through the volute air outlet 601 through the through-out portion 106 and the connecting port 503 into the outlet air duct.

[0128] In some embodiments, the opening direction of the connecting port 503 is set along the length direction of the casing 100. Since the outdoor fresh air flows in a direction intersecting with the length direction of the casing 100 after passing through the fresh air fan, the outdoor fresh air needs to change direction when entering the outlet duct from the fresh air duct, which will reduce the speed of the outdoor fresh air at the connection point between the fresh air duct and the outlet duct. Therefore, the fresh air volute 600 is provided with a connecting portion 640, which is connected to the fresh air component 500. The connecting portion 640 is configured to achieve a transition in the direction of the outdoor fresh air. The volute outlet 601 is opened at the connecting portion 640, and the opening direction of the volute outlet 601 is set along the length direction of the casing 100.

[0129] In some embodiments, the rear shell 120 is provided with an avoidance portion 150, and the front side of the fresh air volute 600 passes through the avoidance portion 150 and is arranged outside the second inner cavity 105 to reduce the thickness of the rear shell 120, thereby reducing the thickness of the air conditioner indoor unit.

[0130] Since the fresh air volute 600 is located in the second inner cavity 105, and the fresh air piece 500 is arranged outside the second inner cavity 105, in order to facilitate the connection between the fresh air volute 600 and the fresh air piece 500, the connecting part 640 is arranged through the through-hole 106 so that the fresh air piece 500 is located outside the second inner cavity 105 and the first inner cavity 104, and the connecting part 640 is connected to the fresh air piece 500 at one end outside the second inner cavity 105 through the through-hole 106.

[0131] As shown in Figures 14 to 20, in order to guide the flow of outdoor fresh air in the air outlet duct, an air guide portion 530 is provided in the fresh air member 500. The air guide portion 530 divides the air outlet duct into multiple air outlet branches 540. Each air outlet branch 540 is correspondingly provided with a branch air outlet. The multiple branch air outlets are distributed along the length direction of the casing 100 and are respectively connected to the second air outlet 103.

[0132] The wall-mounted air-conditioning indoor unit provided by the present invention is provided with a fresh air piece 500, and an air outlet duct is defined inside the fresh air piece 500, and the air outlet duct is used to connect the fresh air duct inside the fresh air volute 600 and the second air outlet 103, so that outdoor fresh air can be output from the second air outlet 103 to the indoor through the air outlet duct; by providing a fourth air outlet 501 on the fresh air piece 500, the fourth air outlet 501 is correspondingly provided with the second air outlet 103, and the second air outlet 103 and the fourth air outlet 501 are respectively extended along the length direction of the casing 100, so that the outdoor fresh air can be output from the second air outlet 103 to the indoor through the fourth air outlet 501, thereby increasing the air outlet range of the outdoor fresh air.

[0133] The fresh air component 500 is usually designed as a split structure to facilitate cleaning of the air outlet duct inside the fresh air component 500.

[0134] The fresh air component 500 includes a first component 510 and a second component 520. The first component 510 and the second component 520 extend along the length direction of the casing 100 respectively. The first component 510 is arranged toward the front side plate 110 of the casing 100, and the second component 520 is arranged toward the heat exchanger 400. The first component 510 and the second component 520 are arranged relative to each other along the thickness direction of the casing 100 and jointly define an air outlet duct; the fourth air outlet 501 and the connecting port 503 are jointly defined by the first component 510 and the second component 520.

[0135] In some embodiments, the first sub-component 510 is provided with an extension portion 550, which is located at one end of the first sub-component 510 along the length direction of the casing 100, and the extension portion 550 is located at the volute air outlet 601 and is arranged corresponding to the volute air outlet 601; the second sub-component 520 is provided with a bending portion 560, and the bending portion 560 extends along the thickness direction of the casing 100. The bending portion 560, the extension portion 550 and the edge of the through-portion 106 jointly define a transition cavity, and the air outlet duct is connected with the fresh air duct through the transition cavity; it should be noted that the connecting port 503 is jointly defined by the bending portion 560 and the extension portion 550, and the opening direction of the connecting port 503 is set toward the rear side of the casing 100, and the connecting port 503, that is, the opening of the transition cavity is set toward the rear side of the casing 100.

[0136] It should be noted that the length of the first segment 510 exceeds the length of the second segment 520 .

[0137] In the prior art, the second air outlet 103 is usually opened on the side of the casing 100 facing the user. Its purpose is, on the one hand, to allow the outdoor fresh air to be delivered to the user's periphery as quickly as possible; on the other hand, since the second air outlet 103 is in the shape of a long strip extending along the length direction of the casing 100, it is not easy to quickly identify the second air outlet 103 from the outside of the air-conditioning indoor unit, resulting in poor visualization of the outdoor fresh air. Opening the second air outlet 103 on the side of the casing 100 facing the user can increase the visualization of the outdoor fresh air to a certain extent, so that the user can intuitively see the outdoor fresh air being output from the second air outlet 103 to the room, and it can also help the user distinguish whether the air-conditioning indoor unit has a fresh air function.

[0138] However, the second air outlet 103 is opened on the side of the casing 100 facing the user, which easily causes outdoor fresh air to blow directly on the user, especially when the temperature difference between the outdoor fresh air and the air-conditioned air is large. The outdoor fresh air is output to the room through the second air outlet 103, and the air-conditioned air is output to the room through the first air outlet 102. The user will be exposed to two outdoor fresh air and air-conditioned air with a large temperature difference, which may easily cause physical discomfort and reduce the user experience. In addition, indoor dust can easily enter the casing 100 through the second air outlet 103.

[0139] At present, according to different needs of users, the opening position of the second air outlet 103 and the opening of the second air outlet 103 are not fixed, but have a variety of different ways.

[0140] 1 to 25 show some embodiments of the wall-mounted air conditioner indoor unit of the present disclosure. In this embodiment, the second air outlet 103 is provided at the bottom front side of the casing 100, and the opening direction of the second air outlet 103 is tilted downward.

[0141] Since the second air outlet 103 is opened on the front side of the casing 100, indoor impurities can easily enter the air outlet duct through the second air outlet 103, which will affect the quality of the outdoor fresh air. Therefore, in this embodiment, the second air outlet 103 is opened at the bottom of the front side of the casing 100, and the opening direction of the second air outlet 103 is tilted downward to increase the difficulty of dust entering the air outlet duct through the second air outlet 103.

[0142] For example, the second air outlet 103 is opened on the front side of the casing 100 and is arranged close to the first air outlet 102. The second air outlet 103 is located above the first air outlet 102, so that when the outdoor fresh air is output to the room from the second air outlet 103, the outdoor fresh air can be mixed with the air-conditioned air output to the room from the first air outlet 102, thereby reducing the temperature difference between the outdoor fresh air and the air-conditioned air, and further reducing the user's discomfort caused by being exposed to two airs with a large temperature difference.

[0143] It should be noted that the force exerted by the fresh air fan on the air is smaller than the force exerted by the heat exchange fan 300 on the air. The transportation distance of outdoor fresh air in the room is usually smaller than the transportation distance of air-conditioning air in the room. After the outdoor fresh air is mixed with the air-conditioning air, the outdoor fresh air can be transported over a longer distance indoors with the help of the air-conditioning air.

[0144] Since the second air outlet 103 is opened at the bottom front side of the casing 100, in order to cooperate with the second air outlet 103, the fourth air outlet 501 is also opened on the side of the fresh air part 500 facing the front side panel 110, so that the opening of the fourth air outlet 501 is set toward the bottom front side of the casing 100, thereby increasing the air outlet efficiency of the outdoor fresh air.

[0145] In some embodiments, in order to further prevent dust from entering the air outlet duct through the second air outlet 103, the second air outlet 103 is set close to the first air outlet 102 so that when the air guide plate 200 closes the first air outlet 102, the second air outlet 103 can also be closed.

[0146] For example, when the air deflector 200 opens the first air outlet 102, the second air outlet 103 is simultaneously opened; when the air deflector 200 closes the first air outlet 102, the second air outlet 103 is simultaneously closed. By controlling the opening and closing states of the second air outlet 103 and the first air outlet 102 through the same air deflector 200, the air deflector 200 can open or close the second air outlet 103 and the first air outlet 102, thereby preventing indoor impurities from entering the air outlet duct when the air conditioner indoor unit is not operating. This arrangement allows the opening and closing states of the second air outlet 103 to be controlled without adding additional components; there is no need to set up additional components to separately open or close the second air outlet 103, thereby simplifying the overall structure.

[0147] As shown in FIG21 , the fresh air fan is operated to introduce outdoor fresh air into the fresh air duct through the volute air inlet 602 and output to the room through the air outlet duct, the fourth air outlet 501 and the second air outlet 103 .

[0148] It should be noted that when outdoor fresh air is output to the room through the second air outlet 103 , the air guide plate 200 needs to rotate to open the second air outlet 103 regardless of whether the air conditioner indoor unit performs heat exchange.

[0149] It should also be noted that since the second air outlet 103 is located above the first air outlet 102, when the air guide plate 200 opens the second air outlet 103, the first air outlet 102 is not necessarily in a fully open state. When the air guide plate 200 closes the second air outlet 103, the first air outlet 102 is in a fully closed state. This is common knowledge in the field and will not be elaborated on.

[0150] Since the outlet duct extends along the length of the housing 100, and the opening of the volute outlet 601 is arranged toward the front of the housing 100, it can be seen that the outdoor fresh air needs to change direction at least once when entering the outlet duct from the fresh air duct. Therefore, to facilitate the connection between the outlet duct and the fresh air duct, the first subassembly 510 and the second subassembly 520 jointly define a transition cavity. The transition cavity includes an opening arranged along the length of the housing 100 and an opening arranged toward the rear of the housing 100. The transition cavity communicates with the outlet duct through the opening of the transition cavity arranged along the length of the housing 100, and the transition cavity communicates with the volute outlet 601 through the opening of the transition cavity arranged toward the rear of the housing 100.

[0151] The operating principle of the wall-mounted air conditioner indoor unit in this embodiment when the fresh air and heat exchange functions are enabled is as follows: the air guide plate 200 opens the second air outlet 103 and the first air outlet 102. The fresh air fan operates, drawing outdoor fresh air into the fresh air duct through the volute inlet 602 and into the fresh air duct from the volute outlet 601 through the outlet portion 106. The outdoor fresh air then passes through the fourth air outlet 501 and is output from the second air outlet 103 to the indoor room. The heat exchange fan 300 operates, drawing indoor air into the first inner cavity 104 through the first air inlet 101. After heat exchange in the heat exchanger 400 to form conditioned air, the conditioned air is output to the indoor room through the first air outlet 102. When the outdoor fresh air is output to the indoor room through the second air outlet 103, it can mix with the conditioned air output to the indoor room through the first air outlet 102, thereby reducing the temperature difference between the outdoor fresh air and the conditioned air, thereby alleviating user discomfort caused by the large temperature difference between the two air types.

[0152] It should be noted that when it is necessary to introduce outdoor fresh air, the wind guide plate 200 opens the second air outlet 103; when it is not necessary to introduce outdoor fresh air, if the indoor air needs to be heat exchanged, the wind guide plate 200 needs to open the first air outlet 102, and the wind guide plate 200 will inevitably open the second air outlet 103 when opening the first air outlet 102. If the indoor air does not need to be heat exchanged, the wind guide plate 200 will close the first air outlet 102 and the second air outlet 103.

[0153] The wall-mounted air-conditioning indoor unit provided in this embodiment extends the second air outlet 103 along the length direction of the casing 100 to increase the air outlet range of outdoor fresh air; the second air outlet 103 is opened on the front side of the casing 100 so that the outdoor fresh air can be mixed with the air-conditioned air outputted to the indoor room by the first air outlet 102 when it is outputted to the indoor room, thereby reducing the user's discomfort caused by the large temperature difference between the outdoor fresh air and the air-conditioned air, and the mixing of the outdoor fresh air and the air-conditioned air can enable the outdoor fresh air to be transported to a farther distance indoors with the help of the air-conditioned air; the second air outlet 103 is opened at the bottom of the front side of the casing 100 and is arranged close to the first air outlet 102 so that the second air outlet 103 and the first air outlet 102 can control the opening and closing states of the second air outlet 103 and the first air outlet 102 through the same air guide plate 200, thereby realizing the control of the opening and closing state of the second air outlet 103 without additional cost, and preventing dust from entering the air outlet duct through the second air outlet 103 when the air-conditioning indoor unit is not working.

[0154] The wall-mounted air conditioner indoor unit provided in this embodiment can prevent dust from entering the interior of the air conditioner indoor unit through the second air outlet 103 when the air conditioner indoor unit is not working, and can mix outdoor fresh air with air-conditioned air, reducing the user's discomfort caused by being exposed to two airs with a large temperature difference.

[0155] Figures 26 to 33 are other embodiments of the wall-mounted air-conditioning indoor unit disclosed in the present invention. In this embodiment, the second air outlet 103 is opened on the front side of the casing 100, and the wall-mounted air-conditioning indoor unit also includes a rotating member 140, which is arranged at the second air outlet 103.

[0156] For example, as shown in Figure 28, the second air outlet 103 is opened on the front side panel 110, and the second air outlet 103 is arranged close to the first air outlet 102 and the second air outlet 103 is located above the first air outlet 102. The purpose is that when the outdoor fresh air is output to the room from the second air outlet 103, the outdoor fresh air can be mixed with the air-conditioned air output to the room from the first air outlet 102, thereby reducing the temperature difference between the outdoor fresh air and the air-conditioned air, and thereby reducing the user's discomfort caused by being exposed to two airs with a large temperature difference.

[0157] It should be noted that, in order to cooperate with the second air outlet 103, the fourth air outlet 501 is also opened on the side of the fresh air part 500 facing the front side panel 110, so that the opening of the fourth air outlet 501 is set toward the front side of the casing 100, thereby increasing the air outlet efficiency of the outdoor fresh air.

[0158] Through the operation of the fresh air fan, outdoor fresh air is introduced into the fresh air duct through the volute air inlet 602, and is output to the room through the air outlet duct, the fourth air outlet 501 and the second air outlet 103.

[0159] Although the second air outlet 103 is opened on the front side panel 110, the visualization effect of outdoor fresh air can be increased to a certain extent, but since the second air outlet 103 is in the shape of an elongated strip, the size of the second air outlet 103 along the height direction of the casing 100 is relatively small, and the wall-mounted air conditioner indoor unit is usually installed in the upper part of the indoor space, and the air conditioner indoor unit is far away from the user. Therefore, the visualization effect of outdoor fresh air of the wall-mounted air conditioner indoor unit is still poor.

[0160] To further enhance the visualization of the outdoor fresh air, as shown in FIG26 , a rotating member 140 is provided at the second air outlet 103. The rotating member 140 is rotatably connected to the housing 100. The axis of the rotating member 140 is arranged along the length of the housing 100. When the outdoor fresh air passes through the rotating member 140, the rotating member 140 spirally rotates around the axis of the rotating member 140 under the action of the outdoor fresh air. Because the outdoor fresh air has kinetic energy, the outdoor fresh air drives the rotating member 140 to rotate. When the outdoor fresh air passes through the rotating member 140, part of the kinetic energy of the outdoor fresh air is converted into the kinetic energy of the rotating member 140, thereby causing the rotating member 140 to rotate. It should be noted that the rotating member 140 protrudes from the side of the front side panel 110 facing away from the rear housing 120, so that the user can clearly see the rotation of the rotating member 140.

[0161] In some embodiments, the rotating member 140 has a spiral structure, and the rotating member 140 is defined to form a spiral channel, which is located on the periphery of the rotating member 140 and is connected to the air outlet duct and the indoor environment respectively; the spiral channel is configured to guide the flow of outdoor fresh air and divert the outdoor fresh air so that the outdoor fresh air is dispersed when passing through the rotating member 140, thereby preventing the outdoor fresh air from blowing directly into the user.

[0162] It should be noted that the rotating member 140 includes a plurality of spiral channels, which are arranged along the length direction of the casing 100. When the outdoor fresh air passes through the rotating member 140, the outdoor fresh air is diverted into the rotating air duct, thereby dispersing the outdoor fresh air.

[0163] As shown in Figure 32, the rotating member 140 includes a plurality of helical segments 143, which are distributed along the length of the housing 100. Two adjacent helical segments 143 are connected end to end along the length of the housing 100, and the helical segments 143 have the same helical angle, so that the rotating member 140 twists along its axis at the same helical angle.

[0164] In some embodiments, the helical angle of the rotating member 140 ranges from 20° to 90°. For example, the helical angle of the rotating member 140 can be 20°, 30°, 40°, 50°, 60°, 70°, 80°, or 90°. In some embodiments, the helical angle of the rotating member 140 can range from 20° to 30°, or 30° to 40°, or 40° to 50°, or 50° to 60°, or 60° to 70°, or 70° to 80°, or 80° to 90°.

[0165] As shown in FIG. 33 , the spiral segment 143 includes a first center line 141 and a second center line 142 . The first center line 141 intersects with the length direction of the housing 100 , and the second center line 142 extends along the length direction of the housing 100 .

[0166] In some embodiments, the first center line 141 and the second center line 142 are perpendicular to each other.

[0167] In some embodiments, the distance L between the first center lines 141 of two adjacent spiral segments 143 may range from 30 mm to 120 mm. For example, L may be 30 mm, 50 mm, 70 mm, 90 mm, 110 mm, or 120 mm. In some embodiments, L may range from 30 mm to 50 mm, 50 mm to 70 mm, 70 mm to 90 mm, 90 mm to 110 mm, or 110 mm to 120 mm.

[0168] In some embodiments, the spiral section 143 is made of a long strip of plate material, and the spiral section 143 can be manufactured by twisting the long strip of plate material around the plate axis at a certain spiral angle.

[0169] The spiral segment 143 includes an edge disposed along the length of the housing 100, and the maximum value of the thickness of the edge is the thickness at the center of the spiral segment 143. The edge is the side of the spiral segment 143, and the center of the spiral segment 143 is the middle portion of the spiral segment 143.

[0170] The thickness of the spiral section 143 decreases gradually from its center along the first center line 141 toward the edge. By designing the spiral section 143 to be thin at both sides and thick in the middle, not only the weight of the spiral section 143 can be reduced, but also the material of the spiral section 143 can be easily twisted to form the spiral section 143 during the manufacturing process of the spiral section 143.

[0171] In some embodiments, the angle between the surface of the helical segment 143 and a horizontal plane passing through the first center line 141 along the length direction of the housing 100 ranges from 0.5° to 2°.

[0172] In practice, by first performing a demolding operation on the material of the rotating part 140, the long strip of plate is made into a structure that is thin on both sides and thick in the middle, and then the long strip of plate is twisted along its axis at the same spiral angle, so that the spiral section 143 of the rotating part 140 can be manufactured into a structure that is thin on both sides and thick in the middle.

[0173] In some embodiments, the draft angle of the long strip plate ranges from 0.5° to 2°.

[0174] In practical applications, the surface of the rotating member 140 can be designed to be an eye-catching color such as bright yellow to further enhance the visualization effect of the outdoor fresh air.

[0175] The operating principle of the wall-mounted air conditioner indoor unit in this embodiment is as follows: The fresh air fan operates, drawing outdoor fresh air into the fresh air duct through the volute inlet 602 and into the outlet duct through the volute outlet 601, through the outlet portion 106, and finally, through the fourth outlet 501 and the second outlet 103 to the indoor space. As the outdoor fresh air is output from the second outlet 103 to the indoor space, it passes through the rotating element 140. This rotation drives the rotating element 140 to enhance the visual effect of the outdoor fresh air. Simultaneously, the outdoor fresh air is dispersed and diverted by the rotating element 140, preventing it from directly reaching the user.

[0176] The wall-mounted air-conditioning indoor unit in this embodiment is provided with a rotating part 140 at the second air outlet 103, so that when the outdoor fresh air passes through the rotating part 140, the outdoor fresh air drives the rotating part 140 to rotate, thereby increasing the visualization effect of the outdoor fresh air; at the same time, when the outdoor fresh air passes through the rotating part 140, the rotating part 140 will disperse the outdoor fresh air, which can prevent the outdoor fresh air from blowing directly on the user and causing discomfort to the user; by designing the rotating part 140 as a spiral structure, not only can the outdoor fresh air drive the rotating part 140 to rotate conveniently, but the spiral channel of the rotating part 140 can also guide the flow of the outdoor fresh air and divert the outdoor fresh air.

[0177] The wall-mounted air-conditioning indoor unit in this embodiment has a good visualization effect and can prevent outdoor fresh air from blowing directly onto the user.

[0178] 34 to 49 are an embodiment of the wall-mounted air conditioner indoor unit disclosed herein. In this embodiment, the second air outlet 103 is provided on the front side of the housing 100 .

[0179] When the temperature difference between the outdoor fresh air and the conditioned air is large, the outdoor fresh air is output to the room through the second air outlet 103, and the conditioned air is output to the room through the first air outlet 102. The user will be exposed to two airs with a large temperature difference, which can easily cause physical discomfort and reduce the user experience. Therefore, in this embodiment, by providing a fifth air outlet 502 in the fresh air element 500, the air outlet duct is connected to the first inner cavity 104 through the fifth air outlet 502, allowing the outdoor fresh air in the air outlet duct to enter the first inner cavity 104 and come into contact with the heat exchanger 400. The heat exchanger 400 heats the outdoor fresh air to form conditioned air, thereby reducing the temperature difference between the outdoor fresh air and the conditioned air. The outdoor fresh air that has been heat-exchanged to form conditioned air is also output to the room through the first air outlet 102.

[0180] It should be noted that the second air outlet 103 is opened on the front side panel 110, and the fourth air outlet 501 is also correspondingly opened on the side of the fresh air component 500 facing the front side panel 110 of the casing 100, so that the fourth air outlet 501 is correspondingly arranged with the second air outlet 103.

[0181] In some embodiments, an air outlet grille 111 is provided at the second air outlet 103 , and the air outlet grille 111 is connected to the front side panel 110 to prevent dust and the like from entering the fresh air duct through the second air outlet 103 .

[0182] As shown in Figure 39, through the operation of the fresh air fan, the outdoor fresh air is introduced into the fresh air duct from the volute air inlet 602 and output to the first inner cavity 104 from the fifth air outlet 502 through the air outlet duct. Through the operation of the heat exchange fan 300, the outdoor fresh air in the first inner cavity 104 is brought into contact with the heat exchanger 400 and is heat-exchanged through the heat exchanger 400 to form air-conditioned air, and the air-conditioned air is output to the room from the first air outlet 102.

[0183] Because the outdoor fresh air is heated and converted into conditioned air before being output indoors through the first air outlet 102, the user is exposed only to the conditioned air, thus avoiding the discomfort caused by being exposed to air of two different temperatures simultaneously. It should be noted that the fifth air outlet 502 is located on the side of the fresh air element 500 facing the heat exchanger 400, allowing the outdoor fresh air in the outlet duct to pass through the fifth air outlet 502 and enter the first inner cavity 104; the branch air outlet is also connected to the fifth air outlet 502.

[0184] The fifth air outlet 502 also extends along the length of the housing 100 to increase the efficiency of outputting outdoor fresh air in the air outlet duct into the first inner cavity 104 .

[0185] Since the fresh air part 500 is provided with a fourth air outlet 501 and a fifth air outlet 502 at the same time, that is, the air outlet duct is connected to both the second air outlet 103 and the first inner cavity 104, it is easy to cause confusion in the discharge of outdoor fresh air in the air outlet duct. Therefore, this embodiment is also provided with a switching component 900, which is used to control the switching status of the fourth air outlet 501 and the fifth air outlet 502, that is, the switching component 900 is configured to make the air outlet duct selectively connected to the second air outlet 103 or the first inner cavity 104.

[0186] When the temperature difference between the outdoor fresh air and the air-conditioning air is large, the switching component 900 closes the fourth air outlet 501 and opens the fifth air outlet 502, so that the air outlet duct is connected to the first inner cavity 104 and the air outlet duct is disconnected from the second air outlet 103. The fresh air fan is operated to introduce the outdoor fresh air into the fresh air duct from the volute air inlet 602 and output it from the fifth air outlet 502 to the first inner cavity 104 through the air outlet duct; the heat exchange fan 300 is operated to introduce the indoor air into the first inner cavity 104 from the first air inlet 101, and the outdoor fresh air and indoor air in the first inner cavity 104 are in contact with the heat exchanger 400. The outdoor fresh air and indoor air are heat-exchanged through the heat exchanger 400 to form air-conditioning air, and the air-conditioning air is output to the room from the first air outlet 102.

[0187] When the temperature difference between the outdoor fresh air and the air-conditioning air is not large, the room switching component 900 opens the fourth air outlet 501 and closes the fifth air outlet 502, so that the air outlet duct is connected to the second air outlet 103 and the air outlet duct is disconnected from the first inner cavity 104. The fresh air fan is operated to introduce the outdoor fresh air into the fresh air duct from the volute air inlet 602, pass through the air outlet duct, and output to the room from the fourth air outlet 501 through the second air outlet 103; the heat exchange fan 300 is operated to introduce the indoor air into the first inner cavity 104 from the first air inlet 101, and after heat exchange through the heat exchanger 400 to form air-conditioning air, the air-conditioning air is output to the room from the first air outlet 102.

[0188] It should be noted that the fourth air outlet 501 and the fifth air outlet 502 are controlled by the same switching component 900 to simplify the overall structure. When the switching component 900 closes the fourth air outlet 501, the fifth air outlet 502 is opened. When the switching component 900 opens the fourth air outlet 501, the fifth air outlet 502 is closed.

[0189] For example, as shown in FIG48 , the switching assembly 900 includes a rotating shaft 920 and a baffle 910. The rotating shaft 920 is rotatably connected to the fresh air member 500. The rotation axis 920 of the rotating shaft 920 is arranged along the length direction of the housing 100. The rotating shaft 920 is connected to a driving member, which is configured to drive the rotating shaft 920 to rotate. The baffle 910 is connected to the rotating shaft 920 and is located in the air outlet duct to open or close the fourth air outlet 501 and open or close the fifth air outlet 502. It should be noted that the fourth air outlet 501 and the fifth air outlet 502 are arranged correspondingly. When the baffle 910 closes the fourth air outlet 501, the fifth air outlet 502 is opened; when the baffle 910 opens the fourth air outlet 501, the fifth air outlet 502 is closed.

[0190] It should be noted that in some embodiments, the fifth air outlet 502 is provided in the second sub-component 520. The second sub-component 520 is provided with a fresh air component connection hole 521, and the rotating shaft 920 is disposed within the fresh air component connection hole 521 so that the rotating shaft 920 is rotatably connected to the second sub-component 520. By designing the fresh air component 500 as a split structure, not only the installation of the fresh air component 500 is facilitated, but also the installation of the switching assembly 900 is facilitated.

[0191] When the temperature difference between the outdoor fresh air and the air-conditioning air is not large, the driving member drives the rotating shaft 920 to rotate, so that the baffle 910 opens the fourth air outlet 501 and closes the fifth air outlet 502. Through the operation of the fresh air fan, the outdoor fresh air is introduced into the fresh air duct through the volute air inlet 602, passes through the air outlet duct, and is output to the room through the fourth air outlet 501 and the second air outlet 103.

[0192] In this case, the outdoor fresh air does not undergo heat exchange processing in heat exchanger 400. The outdoor fresh air and the conditioned air are discharged independently and output into the room through different air outlets. Since the temperature difference between the outdoor fresh air and the conditioned air is small, even if the user is exposed to both the outdoor fresh air and the conditioned air at the same time, the discomfort caused by the temperature difference is relatively mild. It should be noted that in this case, the outdoor fresh air does not pass through first air outlet 102, so the air guide plate 200 can close first air outlet 102.

[0193] When the temperature difference between the outdoor fresh air and the air-conditioning air is large, the driving member drives the rotating shaft 920 to rotate so that the baffle 910 closes the fourth air outlet 501 and opens the fifth air outlet 502. The fresh air fan operates to introduce the outdoor fresh air into the fresh air duct from the volute air inlet 602 and output it from the fifth air outlet 502 to the first inner cavity 104 through the air outlet duct. The heat exchange fan 300 operates to bring the outdoor fresh air in the first inner cavity 104 into contact with the heat exchanger 400 and is heat-exchanged by the heat exchanger 400 to form air-conditioning air, and then the air-conditioning air is output to the room from the first air outlet 102.

[0194] At this time, the outdoor fresh air is heated by the heat exchanger 400 to form air-conditioned air. Since the indoor air is also heated by the heat exchanger 400 to form air-conditioned air, and when the air-conditioning indoor unit is working, the heat exchange efficiency of the heat exchanger 400 is usually the same. Therefore, the air-conditioned air formed by heat exchange of the outdoor fresh air and the air-conditioned air formed by heat exchange of the indoor air are usually the same in temperature. Only air-conditioned air of one temperature is output to the room, thereby avoiding the user's discomfort caused by being exposed to two kinds of wind with a large temperature difference.

[0195] It should be noted that when the outdoor fresh air passes through the heat exchanger 400 for heat exchange, the air guide plate 200 needs to open the first air outlet 102 so that the conditioned air can be output from the first air outlet 102 to the room.

[0196] It should also be noted that when the first air inlet 101 is not closed, the operation of the heat exchange fan 300 will cause indoor air to enter the first inner cavity 104 through the first air inlet 101. This means that when outdoor fresh air is introduced into the first inner cavity 104 and contacts the heat exchanger 400 for heat exchange, indoor air will also enter the first inner cavity 104 through the first air inlet 101. The outdoor fresh air and indoor air may mix in the first inner cavity 104 to form mixed wind.

[0197] In addition, it should be noted that when the temperature difference between the outdoor fresh air and the air-conditioning air is large, the mixing effect of the outdoor fresh air and the indoor air is good. On the one hand, this is because both the outdoor air and the indoor air are heat-exchanged to form air-conditioning air. On the other hand, since both the outdoor fresh air and the indoor air are introduced into the first inner cavity 104, the outdoor fresh air and the indoor air may be mixed in the first inner cavity 104 to form mixed air.

[0198] Since the force exerted by the heat exchange fan 300 on the air is usually greater than the force exerted by the fresh air fan on the air, the transportation distance of the outdoor air when it is heated by the heat exchanger 400 to form air-conditioned air and then output to the indoor room is longer than the transportation distance of the outdoor fresh air when it is not heated by the heat exchanger 400 and output to the indoor room.

[0199] In some embodiments, the wall-mounted air-conditioning indoor unit in this embodiment also includes a temperature detection component and a controller. The temperature detection component is configured to detect the outdoor temperature and the air-conditioning air temperature, thereby obtaining the temperature difference between the outdoor fresh air and the air-conditioning air. The controller controls the operation of the driving component according to the temperature difference obtained by the temperature detection component, thereby controlling the air outlet mode of the outdoor fresh air.

[0200] In some embodiments, the temperature detection component includes an outdoor temperature sensor and an indoor temperature sensor. The outdoor temperature sensor is configured to detect the outdoor temperature, and the indoor temperature sensor is configured to detect the air-conditioning wind temperature. The outdoor temperature sensor and the indoor temperature sensor are electrically connected to the controller respectively, and the controller is also electrically connected to the driving member. When the absolute value of the difference between the outdoor temperature and the indoor temperature exceeds T, the controller controls the driving member to drive the rotating shaft 920 to move, so that the baffle 910 opens the fourth air outlet 501 and closes the fifth air outlet 502.

[0201] It should be noted that the user can automatically control the operation of the switching component 900 based on the detection results of the temperature detection component, or manually control the operation of the switching component 900 based on personal preferences and habits. It should also be noted that the user can select the specific value of the absolute value T of the temperature difference based on personal preferences and habits.

[0202] The operating principle of the wall-mounted indoor air conditioner in this embodiment is as follows: when the temperature difference between the outdoor fresh air and the conditioned air is large, the driving member drives the rotating shaft 920 to rotate, causing the damper 910 to close the fourth air outlet 501 and open the fifth air outlet 502. The fresh air fan operates, drawing outdoor fresh air into the fresh air duct through the volute air inlet 602, and then outputting it through the outlet duct and out of the fifth air outlet 502 into the first inner chamber 104. The heat exchange fan 300 operates, drawing indoor air into the first inner chamber 104 through the first air inlet 101. The outdoor fresh air and indoor air in the first inner chamber 104 come into contact with the heat exchanger 400, where they exchange heat to form conditioned air, which is then output to the room through the first air outlet 102. At this point, the outdoor fresh air and indoor air mix and exchange heat through the heat exchanger 400 to form conditioned air, so that the user receives only conditioned air of one temperature, thereby avoiding the discomfort caused by being exposed to two air streams with a large temperature difference.

[0203] When the temperature difference between the outdoor fresh air and the conditioned air is small, the driving member drives the rotating shaft 920 to rotate, so that the baffle 910 opens the fourth air outlet 501 and closes the fifth air outlet 502. The fresh air fan is operated to introduce the outdoor fresh air into the fresh air duct through the volute air inlet 602, passes through the air outlet duct, and is output to the room through the fourth air outlet 501 and the second air outlet 103. The heat exchange fan 300 is operated to introduce the indoor air into the first inner cavity 104 through the first air inlet 101. After heat exchange in the heat exchanger 400 to form conditioned air, the conditioned air is output to the room through the first air outlet 102. At this time, the outdoor fresh air does not undergo heat exchange processing in the heat exchanger 400. The outdoor fresh air and the conditioned air are independently discharged and output to the room through different air outlets. Since the temperature difference between the outdoor fresh air and the conditioned air is small at this time, even if the user is exposed to both the outdoor fresh air and the conditioned air at the same time, the discomfort caused by the temperature difference is also weak.

[0204] The wall-mounted air conditioner indoor unit of this embodiment is provided with a fifth air outlet 502 on the fresh air element 500, and the fifth air outlet 502 is connected to the first inner cavity 104, so that the outdoor fresh air can enter the first inner cavity 104 through the fifth air outlet 502 and mix with the indoor air to form mixed air. The mixed air is heated by the heat exchanger 400 to form conditioned air and then output to the room through the first air outlet 102, so as to reduce the temperature difference between the outdoor fresh air and the indoor air, and avoid the user from feeling strong discomfort due to being exposed to two kinds of air with a large temperature difference. By setting a switching component 900, the switching component 900 is used to open or close the fourth air outlet 501 and to open or close the fifth air outlet 502, so that the outdoor fresh air in the air outlet duct can choose the outlet mode and be reliably discharged under a certain outlet mode; by setting the fourth air outlet 501 and the fifth air outlet 502 correspondingly, and using the same switching component 900 to control the opening or closing state of the fourth air outlet 501 and the fifth air outlet 502, the number of switching components 900 can be saved and the overall structure can be simplified.

[0205] In the wall-mounted air-conditioning indoor unit of this embodiment, the air outlet mode of the outdoor fresh air can be selected according to the temperature difference between the outdoor fresh air and the air-conditioning air. When the temperature difference between the outdoor fresh air and the air-conditioning air is small, the outdoor fresh air can be directly blown into the room. When the temperature difference between the outdoor fresh air and the air-conditioning air is large, the outdoor fresh air can be blown into the room after being heated by the heat exchanger 400, thereby avoiding the user's discomfort caused by the large temperature difference between the outdoor fresh air and the air-conditioning air. Among them, the outdoor fresh air has a good mixing effect with the indoor air when it is blown into the room after heat exchange, and the outdoor fresh air can be output over a long distance indoors with the help of the heat exchange fan 300. Moreover, the outdoor fresh air has a good visualization effect and a wide air outlet range.

[0206] Figures 50 to 63 show another embodiment of the wall-mounted air-conditioning indoor unit of the present disclosure. In this embodiment, the opening of the second air outlet 103 faces upward and is arranged close to the first air inlet 101.

[0207] Due to the operation of the heat exchange fan 300, negative pressure will be formed at the first air inlet 101. When the outdoor fresh air is output to the room from the second air outlet 103, it is easy to enter the first inner cavity 104 from the first air inlet 101 under the action of negative pressure. The outdoor fresh air in the first inner cavity 104 comes into contact with the heat exchanger 400 under the action of the operation of the heat exchange fan 300 and is heated by the heat exchanger 400 to form air-conditioned air, and the air-conditioned air is output to the room from the first air outlet 102.

[0208] By introducing outdoor fresh air into the first inner cavity 104 and performing heat exchange by the heat exchanger 400 to form conditioned air, the user's discomfort caused by being exposed to two airs with a large temperature difference can be reduced.

[0209] When the fresh air is turned on alone, the fresh air fan is operated to introduce the outdoor fresh air into the fresh air duct through the volute air inlet 602, enter the air outlet duct through the volute air outlet 601, and then output to the room through the fourth air outlet 501 and the second air outlet 103.

[0210] In some embodiments, the second air outlet 103 is opened upward. This can shorten the distance between the second air outlet 103 and the first air inlet 101, increasing the speed at which outdoor fresh air enters the first inner cavity 104. Furthermore, it can prevent the outdoor fresh air from blowing directly onto the user when the second air outlet 103 is turned on, causing discomfort to the user. It should be noted that the second air outlet 103 is defined by the front side panel 110 and the rear housing 120. It should also be noted that the fourth air outlet 501 is also correspondingly located at the top of the fresh air member 500 and opened upward, so that the fourth air outlet 501 is arranged correspondingly to the second air outlet 103.

[0211] When the temperature difference between indoor and outdoor is large, if the fresh air is turned on separately, the outdoor fresh air is directly input into the room, and the user is easily uncomfortable with the outdoor fresh air with a large temperature difference from the indoor temperature. The user can also choose the air outlet mode in which the outdoor fresh air is heated by the heat exchanger 400 before being output to the room. It should be noted that although the air-conditioned air is not output to the room at this time, the user is still exposed to two airs of different temperatures, namely the outdoor fresh air and the indoor air.

[0212] The operation of the heat exchange fan 300 causes indoor air to enter the first inner cavity 104 through the first air inlet 101. This means that when outdoor fresh air enters the first inner cavity 104 and exchanges heat with the heat exchanger 400, indoor air will also enter the first inner cavity 104 through the first air inlet 101. At the same time, because the second air outlet 103 is located near the first air outlet 102, the operation of the heat exchange fan 300 will also cause the outdoor fresh air output from the second air outlet 103 to enter the first inner cavity 104 through the first air outlet 102.

[0213] It should be noted that the outdoor fresh air and indoor air typically mix within the first inner cavity 104 to form mixed air. This mixed air is then heated to form conditioned air and outputted indoors through the first air outlet 102. Therefore, in the air outlet method where the outdoor fresh air is heated by the heat exchanger 400 before being outputted indoors, the mixing effect of the outdoor fresh air and indoor air is improved. It should also be noted that because the force exerted on the air by the heat exchange fan 300 is typically greater than the force exerted on the air by the fresh air fan, the distance the outdoor fresh air is transported indoors in this air outlet method is greater than the distance the outdoor fresh air is transported indoors when it is directly outputted indoors through the second air outlet 103.

[0214] In this embodiment, the outdoor fresh air in the wall-mounted air conditioner indoor unit is discharged in two ways: the outdoor fresh air is directly discharged to the indoor through the second air outlet 103 , and the outdoor fresh air is heated by the heat exchanger 400 to form conditioned air and then discharged to the indoor through the first air outlet 102 .

[0215] In the air outlet method where outdoor fresh air is directly output to the indoor space through the second air outlet 103, the outdoor fresh air does not enter the first inner cavity 104 and come into contact with the heat exchanger 400. Instead, the outdoor fresh air flows under the action of the fresh air fan. Therefore, the heat exchange fan 300 is not involved in the outdoor fresh air output process. Furthermore, since the outdoor fresh air is output to the indoor space through the second air outlet 103, the air guide plate 200 and the first air outlet 102 are not involved in the outdoor fresh air output process. This air outlet method allows the air conditioner indoor unit to start fresh air independently, and this air outlet method is simple and energy-saving.

[0216] In the air outlet method in which the outdoor fresh air is heated by the heat exchanger 400 to form air-conditioned air and then output to the indoor room through the first air outlet 102, the outdoor fresh air is first output to the indoor room through the second air outlet 103 and then enters the first inner cavity 104 through the first air inlet 101 under the action of the heat exchange fan 300. The outdoor fresh air entering the first inner cavity 104 contacts the heat exchanger 400 and is heated to form air-conditioned air. Therefore, this air outlet method can reduce the temperature difference between the outdoor fresh air and the air-conditioned air; since the indoor air is also introduced into the first inner cavity 104 when the heat exchange fan 300 is working, the mixing effect of the outdoor fresh air and the indoor air is good in this air outlet method; and since the outdoor fresh air is heated to form air-conditioned air and then output to the indoor room through the first air outlet 102, in this air outlet method, the outdoor fresh air is transported indoors over a longer distance with the help of the heat exchange fan 300.

[0217] It should be noted that, since the second air outlet 103 is connected to the indoor space, the outdoor fresh air may not be completely introduced into the first inner cavity 104, and part of the outdoor fresh air may still be output to the indoor space through the second air outlet 103. However, since the second air outlet 103 is opened upward, the outdoor fresh air is output to the indoor space from the second air outlet 103 at a long distance from the user. During the diffusion process indoors, the outdoor fresh air will exchange heat with the indoor air until the outdoor fresh air temperature is similar to the indoor air temperature. Therefore, when this part of the outdoor fresh air output to the indoor space from the second air outlet 103 comes into contact with the user, it will cause less discomfort to the user.

[0218] The outdoor fresh air and the indoor air may be mixed in the first inner cavity 104, or they may be heated by the heat exchanger 400 to form air-conditioned air and then mixed. It should be noted that the mixing process of the outdoor fresh air and the indoor air is common knowledge in this field and will not be repeated here.

[0219] In this embodiment, the first sub-component 510 extends along the length direction of the casing 100, the second sub-component 520 is connected to one end of the first sub-component 510 along the length direction of the casing 100 and is connected to the fresh air volute 600, the fourth air outlet 501 is opened in the first sub-component 510, and the connecting port 503 is opened in the second sub-component 520 to connect the interior of the first sub-component 510 with the interior of the second sub-component 520 and jointly define an air outlet duct.

[0220] The second sub-component 520 further includes a sixth air inlet 506 , which is provided at the connection between the fresh air component 500 and the fresh air volute 600 , so as to connect the fresh air duct inside the fresh air volute 600 with the air outlet duct inside the fresh air component 500 .

[0221] Designing the fresh air component 500 as a split structure not only facilitates installation and removal of the fresh air component 500, but also facilitates cleaning of the first sub-component 510. Since the second air outlet 103 and the fourth air outlet 501 are positioned upward, dust and the like easily enter the air duct from the second air outlet 103 through the fourth air outlet 501. Therefore, the first sub-component 510 requires regular cleaning. However, the second sub-component 520 lacks the fourth air outlet 501, and outdoor fresh air is output from the interior of the second sub-component 520 to the interior of the first sub-component 510. Therefore, dust and the like that enter the first sub-component 510 are less likely to enter the second sub-component 520, and the second sub-component 520 typically requires less frequent cleaning than the first sub-component 510.

[0222] The working principle of the wall-mounted air-conditioning indoor unit in this embodiment is as follows: when the fresh air is turned on alone, the heat exchange fan 300 does not work, and the fresh air fan works. Through the operation of the fresh air fan, the outdoor fresh air is introduced into the fresh air duct from the volute air inlet 602, passes through the volute air outlet 601 and the sixth air inlet 506, and enters the air outlet duct. Then the outdoor fresh air is output to the room from the fourth air outlet 501 through the second air outlet 103.

[0223] When the fresh air and air-conditioning air are turned on at the same time, the heat exchange fan 300 and the fresh air fan are both working. Through the operation of the fresh air fan, the outdoor fresh air is introduced into the fresh air duct through the volute air inlet 602, passes through the volute air outlet 601, and enters the air outlet duct of the outlet part 106, and then the outdoor fresh air is output to the room through the fourth air outlet 501 and the second air outlet 103. At this time, through the operation of the heat exchange fan 300, a negative pressure is formed in the first inner cavity 104, and the indoor air is introduced into the first inner cavity 104 through the first air inlet 101. At the same time, the outdoor fresh air output to the room through the second air outlet 103 is also introduced into the first inner cavity 104 through the first air inlet 101. The outdoor fresh air and the indoor air are mixed in the first inner cavity 104 to form mixed air. Through the continued operation of the heat exchange fan 300, the mixed air is led to contact with the heat exchanger 400 and is heat exchanged by the heat exchanger 400 to form air-conditioning air. Finally, the air-conditioning air is output to the room through the first air outlet 102.

[0224] It should be noted that when the outdoor fresh air passes through the heat exchanger 400 for heat exchange, the air guide plate 200 needs to open the first air outlet 102 so that the conditioned air can be output from the first air outlet 102 to the room.

[0225] It should also be noted that when the fresh air is turned on alone, if the temperature difference between indoor and outdoor is large at this time, both the heat exchange fan 300 and the fresh air fan can be operated so that the outdoor fresh air can enter the first inner cavity 104 and be heated by the heat exchanger 400 to form air-conditioned air, thereby avoiding discomfort to users due to the large temperature difference between the outdoor fresh air and the indoor temperature.

[0226] The wall-mounted air-conditioning indoor unit in this embodiment opens the second air outlet 103 at the top of the casing 100 and is arranged close to the first air inlet 101, so that the outdoor fresh air output to the room can enter the first inner cavity 104 through the first air inlet 101 and mix with the indoor air to form mixed air. The mixed air is heated by the heat exchanger 400 to form air-conditioned air and then output to the room through the first air outlet 102, so as to reduce the temperature difference between the outdoor fresh air and the indoor air and / or the outdoor fresh air and the air-conditioned air, thereby avoiding the user from feeling strong discomfort due to being exposed to two airs with a large temperature difference.

[0227] The wall-mounted air-conditioning indoor unit in this embodiment includes a variety of outdoor fresh air outlet modes. The user can choose whether the outdoor fresh air is blown directly into the room, or whether the outdoor fresh air is blown into the room after heat exchange by the heat exchanger 400. Among them, the outdoor fresh air has a good mixing effect with the indoor air when it is blown into the room after heat exchange, and the outdoor fresh air is transported over a long distance in the room. The outlet mode of blowing the outdoor fresh air directly into the room is simple and energy-saving. The wall-mounted air-conditioning indoor unit in this embodiment can not only reduce the user's discomfort caused by the large temperature difference between the outdoor fresh air and the air-conditioning air, but also has a good visualization effect of the outdoor fresh air and a wide range of outdoor fresh air outlet.

[0228] 64 to 71 show some other embodiments of the wall-mounted air-conditioning indoor unit disclosed herein. In this embodiment, the wall-mounted air-conditioning indoor unit further includes an air guide portion 530 .

[0229] As shown in Figure 67, the heat exchanger 400 includes a first section 410, a second section 420 and a third section 430, and the first section 410, the second section 420 and the third section 430 respectively extend along the length direction of the casing 100; the first section 410 and the third section 430 are roughly arranged along the height direction of the casing 100, the first section 410 is arranged close to the front side of the casing 100, and the third section 430 is arranged close to the rear side of the casing 100, and the second section 420 is respectively connected to the top of the first section 410 and the top of the third section 430, so that the heat exchanger 400 is roughly a semi-enclosed structure located on the top of the heat exchange fan 300.

[0230] Since the fresh air piece 500 is located in front of the heat exchanger 400, in order to prevent the fresh air piece 500 from affecting the heat exchange effect of the heat exchanger 400, a gap is formed between the fresh air piece 500 and the heat exchanger 400 along the thickness direction of the casing 100, so that the fresh air piece 500, the heat exchanger 400 and the casing 100 jointly define a channel 160, and the channel 160 is connected to the first inner cavity 104, so that the air in the first inner cavity 104 can enter the channel 160, contact the heat exchanger 400, and exchange heat to form air-conditioning air.

[0231] It should be noted that the fresh air member 500 is disposed opposite the first section 410, and the gap between the fresh air member 500 and the heat exchanger 400 is formed by the fresh air member 500 and the first section 410. The first section 410 includes a first side surface 401, which is disposed toward the fresh air member 500 and is used to define the channel 160.

[0232] It should also be noted that a channel opening communicating with the first inner cavity 104 is provided at the top of the channel 160 , so that the air in the first inner cavity 104 can enter the channel 160 through the channel opening.

[0233] In order to install the fresh air piece 500 inside the casing 100 without changing the thickness dimension of the casing 100, the distance between the fresh air piece 500 and the heat exchanger 400 along the thickness direction of the casing 100 is usually minimized. Such a setting will reduce the dimension of the channel 160 along the thickness direction of the casing 100, resulting in the fresh air piece 500 possibly hindering the air in the first inner cavity 104 from entering the channel 160 and contacting the first section 410, thereby reducing the heat exchange effect of the heat exchanger 400.

[0234] It should be noted that, in some embodiments, the size of the first inner cavity 104 along the thickness direction of the casing 100 may even be reduced, so as to achieve the installation of the fresh air component 500 inside the casing 100 without changing the size of the casing 100 in the thickness direction.

[0235] In this embodiment, an air guide portion 530 is provided in the fresh air piece 500, and the air guide portion 530 is used to guide the air in the first inner cavity 104 into the channel 160 to contact and exchange heat with the first section 410, thereby reducing the impact of the fresh air piece 500 on the heat exchange effect of the heat exchanger 400.

[0236] For example, the air guide portion 530 is provided on the side of the fresh air piece 500 facing the first section 410, and the air guide portion 530 is located at the part of the fresh air piece 500 close to the top of the casing 100. The air guide portion 530 makes the dimension between the top of the fresh air piece 500 and the first section 410 along the thickness direction of the casing 100 larger than the dimension between the bottom of the fresh air piece 500 and the first section 410 along the thickness direction of the casing 100, so that the dimension of the top opening of the channel 160 along the thickness direction of the casing 100 is larger than the dimension of the channel 160 close to the bottom of the casing 100 along the thickness direction of the casing 100, so that the channel 160 is roughly trumpet-shaped along the thickness direction of the casing 100, so that more air is introduced into the gap through the air guide portion 530, thereby increasing the heat exchange efficiency between the first section 410 and the air.

[0237] It should be noted that the air guide portion 530 makes the size of the upper end of the fresh air piece 500 along the thickness of the casing 100 smaller than the size of the lower end of the fresh air piece 500 along the thickness of the casing 100.

[0238] The end of the air guide portion 530 facing the top of the casing 100 is the top of the air guide portion 530, and the end of the air guide portion 530 facing the bottom of the casing 100 is the bottom of the air guide portion 530. The distance between the top of the air guide portion 530 and the first section 410 along the thickness direction of the casing 100 is L, and the distance between the bottom of the air guide portion 530 and the first section 410 along the thickness direction of the casing 100 is L, where the minimum value of the L value range is L.

[0239] By making the distance L between the top of the air guide 530 and the heat exchanger 400 greater than the distance L between the bottom of the air guide 530 and the heat exchanger 400, the channel 160 is roughly trumpet-shaped along the thickness direction of the housing 100, thereby increasing the amount of air introduced into the channel 160 by the air guide 530.

[0240] In some embodiments, L1 is 20 mm and L2 is 17 mm.

[0241] Since the air guide portion 530 is located on the side of the fresh air member 500 facing the channel 160 , it can be seen that the air guide portion 530 is also configured to define the channel 160 together with the fresh air member 500 , the first section 410 and the casing 100 .

[0242] It should be noted that the side of the fresh air member 500 facing the channel 160 includes an air guide portion 530 and a second side surface 505 . The air guide portion 530 and the second side surface 505 are arranged along the height direction of the casing 100 , and the second side surface 505 is set toward the first section 410 .

[0243] The channel 160 includes a first part 1601 and a second part 1602, the first part 1601 is located above the second part 1602 and the first part 1601 and the second part 1602 are connected to each other; the first part 1601 is jointly defined by the air guide portion 530 and the first section 410; the second part 1602 is jointly defined by the second side 505 and the first section 410; wherein, the top opening of the channel 160 is jointly defined by the air guide portion 530 and the first section 410 and is connected to the first part 1601.

[0244] In this embodiment, the air guide portion 530 is provided so that the dimension of the first portion 1601 along the thickness direction of the casing 100 is larger than the dimension of the second portion 1602 along the thickness direction of the casing 100, so that more air in the first inner cavity 104 can enter the first portion 1601 through the opening, and the air in the first portion 1601 can enter the second portion 1602 through the guiding effect of the air guide portion 530.

[0245] The air guide portion 530 and the upper portion of the first section 410 together define a first portion 1601, and the second side surface 505 and the lower portion of the first section 410 together define a second portion 1602. Ideally, the larger the proportion of the first portion 1601 in the channel 160, the more air enters the channel 160. However, as the proportion of the first portion 1601 increases, the size of the air guide portion 530 along the height direction of the casing 100 will increase. The increase in the size of the air guide portion 530 along the height direction of the casing 100 will reduce the size of the air outlet duct inside the fresh air component 500 along the thickness direction of the casing 100, resulting in a decrease in the fresh air effect of the air conditioner indoor unit. Therefore, the first portion 1601 and the second portion 1602 need to meet an appropriate proportion in the channel 160 so that the air conditioner indoor unit can have both good fresh air performance and heat exchange performance.

[0246] As shown in FIG. 68 , when the air guide portion 530 is projected onto the plane where the first side surface 401 is located, the projection of the bottom of the air guide portion 530 falls into the first side surface 401 .

[0247] The projection of the end of the air guide portion 530 toward the bottom of the housing 100 within the first side surface 401 and the height of the bottom of the first side surface 401 along the housing 100 are h, and the height of the first side surface 401 along the housing 100 is H, wherein h and H satisfy the relationship

[0248] By making h1 and H satisfy the relationship: The first part 1601 and the second part 1602 can have a suitable proportion in the channel 160, which not only enables the air guide part 530 to better guide the air into the channel 160, but also enables the fresh air component 500 to better output outdoor fresh air to the room.

[0249] In other words, the first side surface 401 includes a first dividing line 402 and a second dividing line 403, and the first dividing line 402 and the second dividing line 403 divide the first side surface 401 into three equal parts along the height of the housing 100, that is, the first dividing line 402 is a one-third dividing line of the first side surface 401 along the height direction of the housing 100, and the second dividing line 403 is a two-thirds dividing line of the first side surface 401 along the height direction of the housing 100.

[0250] In some embodiments, the projection position of the bottom of the air guide portion 530 on the first side surface 401 is located within the interval defined by the first dividing line 402 and the second dividing line 403 .

[0251] Since the second portion 1602 is located below the first portion 1601 and the size of the second portion 1602 along the thickness direction of the housing 100 is smaller than the size of the first portion 1601 along the thickness direction of the housing 100, less air enters the second portion 1602.

[0252] As shown in Figures 70-71, the air guide portion 530 includes a straight section 531 and a transition section 532. The straight section 531 and the transition section 532 are interconnected and located above the transition section 532. The minimum value of the distance between the straight section 531 and the heat exchanger 400 along the thickness direction of the casing 100 is the maximum value of the distance between the transition section 532 and the heat exchanger 400 along the thickness direction of the casing 100.

[0253] The function of the straight section 531 is to make the channel opening have a larger size, so that more air in the first inner cavity 104 enters the first part 1601. The function of the transition section 532 is to guide the air to flow in the channel 160, so that the air can enter the second part 1602 for heat exchange.

[0254] It should be noted that when the air in the first inner cavity 104 enters the first part 1601 through the channel opening, the air will continue to move downward for a distance in the first part 1601 due to inertia. Therefore, in the interval where the air moves under the action of inertia, the air guiding part 530 has a weaker effect on guiding the air. Providing the straight line segment 531 can also enable the straight line segment 531 to form a space for inertial movement of air in the first part 1601.

[0255] In some embodiments, the straight segment 531 and the first side surface 401 are disposed parallel to each other along the height direction of the housing 100 .

[0256] In some other embodiments, the straight segment 531 extends beyond the first segment 410 in the height direction of the casing 100, so that more air in the first inner cavity 104 can enter the channel 160.

[0257] As shown in FIG. 69, the distance from the connection of the transition segment 532 and the straight segment 531 to the bottom of the fresh air component 500 in the height direction of the casing 100 is H, and the distance of the first side surface 401 in the height direction of the casing 100 is h. Among them, h and H satisfy the relationship:

[0258] By making h and H satisfy the relationship: The transition segment 532 can preferably guide the air to flow into the second part 1602.

[0259] It should be noted that in some embodiments, the distance of the first side surface 401 in the height direction of the casing 100 is considered to be the distance of the first segment 410 in the height direction of the casing 100.

[0260] By setting the straight segment 531, the channel opening has a larger size, so that more air can enter the first part 1601, and the air entering the first part 1601 can continue to move under the action of inertia; by setting the transition segment 532, not only can the air in the first part 1601 be introduced into the second part 1602, but also the transition from the thinner size of the upper part inside the fresh air component 500 to the thicker size of the lower part inside the fresh air component 500 can be realized, thus ensuring the air outlet effect of the outdoor fresh air.

[0261] In some embodiments, as shown in FIG. 69, the transition segment 532 is an arc segment with a radius size of R.

[0262] The distance between the end of the transition segment 532 far from the straight segment 531 and the end of the straight segment 531 facing the top of the casing 100 in the thickness direction of the casing 100 is a. Among them, a and R satisfy the relationship: 8 < R / a < 50.

[0263] The shape of the transition segment 532 directly affects the air diversion effect of the transition segment 532. Therefore, by making a and R satisfy the relationship: 8 < R / a < 50, the transition segment 532 has a better air diversion effect.

[0264] Although adding an air outlet duct for outdoor fresh air inside the casing 100 reduces the heat exchange space of the heat exchanger 400 to a certain extent, by setting the air guiding part 530 to guide the air to contact the heat exchanger 400, the influence on the heat exchange effect of the heat exchanger 400 is small, and the influence on the air output volume of the air conditioner is small.

[0265] The working principle of the wall-mounted air-conditioning indoor unit in this embodiment is as follows: the heat exchange fan 300 is operated to introduce indoor air into the first inner cavity 104 from the first air inlet 101, and part of the air entering the first inner cavity 104 enters the first part 1601 through the channel opening, and then passes through the transition section 532 to introduce the air into the second part 1602, so that the air in the channel 160 contacts the first section 410 for heat exchange and forms air-conditioned air, which is output to the room through the first air outlet 102.

[0266] The wall-mounted air-conditioning indoor unit in this embodiment extends the second air outlet 103 along the length direction of the casing 100 to increase the air outlet range of outdoor fresh air; the second air outlet 103 is opened on the front side of the casing 100 so that the outdoor fresh air can be mixed with the conditioned air outputted from the first air outlet 102 to the indoor when it is outputted into the room, thereby reducing the user's discomfort caused by the large temperature difference between the outdoor fresh air and the conditioned air, and the mixing of the outdoor fresh air and the conditioned air can enable the outdoor fresh air to be transported to a farther distance indoors with the help of the conditioned air; a fresh air piece 500 is provided, and an air outlet duct is defined inside the fresh air piece 500, and the air outlet duct is used to connect the interior of the fresh air volute 600 with the second air outlet 103, so that the outdoor fresh air can be outputted from the second air outlet 103 to the indoor through the air outlet duct; A fourth air outlet 501 is provided, and the fourth air outlet 501 is provided corresponding to the second air outlet 103, and the second air outlet 103 and the fourth air outlet 501 extend respectively along the length direction of the casing 100, so that the outdoor fresh air passes through the fourth air outlet 501 and is output from the second air outlet 103 to the indoor room; the fresh air component 500 is provided in the casing 100 to ensure the overall appearance of the air-conditioning indoor unit; by providing the air guide portion 530, not only the opening size of the connection between the channel 160 and the first inner cavity 104 can be increased to allow more air to enter the channel 160, but also the air guide portion 530 can guide the air to flow in the channel 160, so that the air in the channel 160 exchanges heat with the side of the heat exchanger 400 toward the fresh air component 500, thereby reducing the influence of the fresh air component 500 on the heat exchange effect of the heat exchanger 400.

[0267] In the wall-mounted air-conditioning indoor unit of this embodiment, the fresh air component 500 is installed inside the casing 100 without changing the overall external dimensions. Not only does the outdoor fresh air have a wide air outlet range and good air outlet effect, but the installation of the fresh air component 500 inside the casing 100 has little effect on the heat exchange effect of the heat exchanger 400 and the air outlet volume of the air-conditioning air.

[0268] Because condensed water is easily generated when air exchanges heat with heat exchanger 400, as shown in Figures 72-88 , the wall-mounted air conditioner indoor unit further includes a first water receiving member located within first inner cavity 104 and below heat exchanger 400. This first water receiving member is configured to receive condensed water generated during the air heat exchange process. It should be noted that for ease of description, the condensed water generated during the air heat exchange process is referred to as heat exchange condensed water.

[0269] The first water receiving member is connected to a drain pipe 830 , and one end of the drain pipe 830 away from the first water receiving member is arranged outdoors. The drain pipe 830 is configured to discharge the heat exchange condensed water outdoors.

[0270] The heat exchanger 400 includes a first section 410, a second section 420 and a third section 430, and the first section 410, the second section 420 and the third section 430 extend respectively along the length direction of the casing 100; the first section 410 and the third section 430 are arranged roughly along the height direction of the casing 100, the first section 410 is arranged close to the front side of the casing 100, and the third section 430 is arranged close to the rear side of the casing 100, and the second section 420 is connected to the top of the first section 410 and the top of the third section 430, respectively, so that the heat exchanger 400 is roughly a semi-enclosed structure located on the top of the heat exchange fan 300.

[0271] Condensed water is easily generated when air passes through the heat exchanger 400 for heat exchange. The condensed water generated by the air heat exchange usually remains on the surface of the heat exchanger 400. The condensed water on the surface of the first section 410 drips along its wall under the action of gravity, and the condensed water on the surface of the third section 430 drips along its wall under the action of gravity. The height of the end of the second section 420 connected to the first section 410 is smaller than the end of the second section 420 connected to the third section, so that the condensed water on the surface of the second section 420 can flow along the wall of the second section 420 to the first section 410 under the action of gravity, and then drip along the wall of the first section 410. This is common knowledge and technology in the field and will not be repeated here.

[0272] The first water receiving part includes a first water receiving portion 131 and a second water receiving portion 132, and the first water receiving portion 131 and the second water receiving portion 132 extend along the length direction of the casing 100 respectively; the first water receiving portion 131 is arranged corresponding to the first section 410, and the second water receiving portion 132 is arranged corresponding to the third section 430. Accordingly, the first water receiving portion 131 is arranged close to the front side of the casing 100, and the second water receiving portion 132 is arranged close to the rear side of the casing 100, so that the first water receiving part can better receive the heat exchange condensed water.

[0273] The first water receiving member is integrated with the base 130 to simplify the overall structure and facilitate production.

[0274] Since the first water receiving portion 131 is arranged close to the front side of the casing 100, the second water receiving portion 132 is arranged close to the rear side of the casing 100, and the first water receiving portion 131 and the second water receiving portion 132 extend respectively along the length direction of the casing 100, therefore, in order to facilitate the heat exchange condensed water received by the first water receiving portion 131 and the second water receiving portion 132 to be discharged to the outside through the drain pipe 830, the base 130 is provided with a guide member 133, which is roughly arranged along the thickness direction of the casing 100 and is respectively connected to the first water receiving portion 131 and the second water receiving portion 132. The guide member 133 is connected to the drain pipe 830 so that the heat exchange condensed water received by the first water receiving portion 131 and the heat exchange condensed water received by the second water receiving portion 132 respectively pass through the guide member 133 and flow into the drain pipe 830.

[0275] In order to increase the drainage effect of the drain pipe 830, the drain pipe 830 is connected to the bottom of the guide member 133, and the guide member 133 includes a second inclined surface arranged downward from the guide member 133 toward the drain pipe 830, so that the heat exchange condensate water flows into the drain pipe 830 along the second inclined surface in an inclined downward path, so that the heat exchange condensate water can better pass through the guide member 133 and flow into the drain pipe 830.

[0276] For example, the flow guide 133 includes a first flow guide portion 1331 and a second flow guide portion 1332, and the first flow guide portion 1331 and the second flow guide portion 1332 are arranged along the thickness direction of the casing 100; wherein, the first flow guide portion 1331 is arranged corresponding to the first water receiving portion 131, and the second flow guide portion 1332 is arranged corresponding to the second water receiving portion 132, and the drain pipe 830 is connected to the connection between the first flow guide portion 1331 and the second flow guide portion 1332, and the first flow guide portion 1331 and the second flow guide portion 1332 respectively include a second inclined surface, and the second inclined surface of the first flow guide portion 1331 and the second inclined surface of the second flow guide portion 1332 are inclined in opposite directions.

[0277] The first guide portion 1331 is arranged to be tilted downward from the front side of the casing 100 to the rear side of the casing 100 along the thickness direction of the casing 100, and the second guide portion 1332 is arranged to be tilted downward from the rear side of the casing 100 to the front side of the casing 100 along the thickness direction of the casing 100, so that the guide member 133 is V-shaped, so that the heat exchange condensed water in the first water receiving portion 131 and the second water receiving portion 132 can flow into the drain pipe 830 faster and better through the guide member 133.

[0278] It should be noted that the connection position between the guide member 133 and the drain pipe 830, that is, the connection between the first guide part 1331 and the second guide part 1332 is usually the position where the guide member 133 has the smallest height. Its purpose is to allow the condensed water received by the first water receiving part 131 and the second water receiving part 132 to flow into the drain pipe 830 better through the corresponding first guide part 1331 and the second guide part 1332.

[0279] In this embodiment, the second air outlet 103 is opened on the front side of the casing 100, and the fourth air outlet 501 is also opened correspondingly on the side of the fresh air component 500 facing the front side panel 110 of the casing 100, so that the fourth air outlet 501 is set correspondingly to the second air outlet 103.

[0280] Since condensation water is easily generated during the process of outputting outdoor fresh air into the room due to the temperature difference between indoor and outdoor, and since the second air outlet 103 is provided on the front side panel 110 and extends along the length of the housing 100, and the fresh air member 500 is provided between the front side panel 110 and the rear housing 120, condensation water entering the rear housing 120 can easily damage the components installed inside the rear housing 120. In this embodiment, a second water receiving member 800 is provided to receive the condensation water generated during the process of outputting outdoor fresh air into the room. For the sake of convenience, the condensation water generated by the outdoor fresh air is referred to as fresh air condensation water.

[0281] For example, as shown in Figure 83, a drain outlet 504 is opened at the bottom of the fresh air part 500, and the drain outlet 504 is connected to the air outlet duct. The second water receiving part 800 is arranged corresponding to the drain outlet 504 so that the fresh air condensation water flows from the drain outlet 504 to the second water receiving part 800.

[0282] In some embodiments, the drain port 504 is defined by a first segment 510 and a second segment 520 .

[0283] Since the second air outlet 103 is opened on the front side of the casing 100, the opening directions of the second air outlet 103 and the fourth air outlet 501 are set toward the front side of the casing 100. In order to allow the condensed water to flow better to the second water receiving part 800, the second water receiving part 800 is defined to form a water receiving channel 801 with a top opening. The second water receiving part 800 is connected to the bottom of the fresh air part 500, and the water receiving channel 801 is connected to the air outlet 504, so that the fresh air condensed water can drip from the drain port 504 to the second water receiving part 800 under the action of gravity.

[0284] The second water receiving member 800 is provided with a first connecting hole 802, and the fresh air member 500 is provided with a first clamping portion. The first clamping portion is provided corresponding to the first connecting hole 802, and the first clamping portion cooperates with the first connecting hole 802 to connect the second water receiving member 800 to the fresh air member 500. It should be noted that the first connecting hole 802 is provided at the top of the second water receiving member 800, and the first clamping portion is provided on the outer wall of the fresh air member 500 facing the front side and the rear side of the housing 100.

[0285] The second water receiving member 800 is provided with a discharge portion 810, which defines a drainage channel 811 therein. The drainage channel 811 is in communication with the water receiving channel 801, and the drainage channel 811 is in communication with a drainage pipe 830, so that fresh air condensed water flows through the drainage channel 811 and enters the drainage pipe 830. It should be noted that the discharge portion 810 is located on a side of the second water receiving member 800 facing the rear side of the housing 100.

[0286] The outlet portion 810 includes a first slope 814 that is arranged downwardly slanted from it toward the drain pipe 830. The fresh air condensed water flows into the drain pipe 830 along the first slope 814 in a downward slanted path. It should be noted that the first slope 814 is the bottom surface of the drainage channel 811.

[0287] The drain pipe 830 is connected to the first inner cavity 104, and the outlet portion 810 is located on the side of the second water receiving member 800 facing the rear side of the casing 100. Therefore, the first inclined surface 814 is set to be inclined downward from the front side of the casing 100 to the rear side of the casing 100 along the thickness direction of the casing 100.

[0288] Since the drain pipe 830 is connected to the first inner cavity 104, and the second water receiving member 800 is located outside the rear housing 120, the base 130 is provided with a connecting portion to facilitate the connection between the drainage channel 811 of the outlet portion 810 and the drain pipe 830. The outlet portion 810 and the connecting portion are correspondingly arranged, so that the outlet portion 810 connects the fresh air condensed water to the drain pipe 830 through the connecting portion. It should be noted that since the second water receiving member 800 is located near the front side of the housing 100, the connecting portion is also located near the front side of the housing 100.

[0289] The drain pipe 830 includes a first water inlet 832 and a second water inlet 831. The first water inlet 832 is located at the connection between the connecting part and the drain pipe 830; the second water inlet 831 is located at the connection between the first guide part 1331 and the second guide part 1332. The opening of the second water inlet 831 is set upward or approximately upward. The heat exchange condensate flows into the drain pipe 830 from the second water inlet 831, and the fresh air condensate flows into the drain pipe 830 from the first water inlet 832.

[0290] The connecting portion is located below the flow guide 133, and the first water inlet 832 is lower than the second water inlet 831. Since the connecting portion is also located near the front side of the housing 100, while the second flow guide 1332 is located near the rear side of the housing 100, the heat exchange condensed water passes through the second flow guide 1332 and enters the drain pipe 830 through the second water inlet 831. After that, it is likely to enter the connecting portion through the first water inlet 832 due to inertia. After entering the connecting portion, the heat exchange condensed water may flow along the connecting portion into the interior of the housing 100, thereby affecting the operation of other components.

[0291] In this embodiment, the connecting portion includes a third inclined surface 1091, so that the third inclined surface 1091 is inclined downwardly from one end of the connecting portion close to the second water receiving member 800 toward the drain pipe 830, and the second inclined surface of the second guide portion 1332 is inclined downwardly from the rear side of the casing 100 toward the drain pipe 830. Therefore, the inclination direction of the third inclined surface 1091 is roughly from the front side of the casing 100 toward the drain pipe 830, so as to increase the resistance of the heat exchange condensed water to flow along the third inclined surface 1091 away from the drain pipe 830, thereby preventing the heat exchange condensed water from flowing back into the connecting portion from the first water inlet 832.

[0292] In some embodiments, the connecting portion is a connecting channel 109 provided on the base 130, and the connecting channel 109 extends roughly along the thickness direction of the casing 100. The connecting channel 109 is connected to the drain pipe 830. The third inclined surface 1091 is the bottom surface of the connecting channel 109, and the end of the outlet portion 810 away from the second water receiving part 800 is provided in the connecting channel 109 to connect the drainage channel 811 with the drain pipe 830.

[0293] In order to prevent the heat exchange condensed water in the second water receiving part 132 from passing through the second guide part 1332 and entering the connecting channel 109 from the first water inlet 832, the downward inclination angle of the connecting channel 109 is usually in the range of 2° to 10°, that is, the angle formed between the third inclined surface 1091 and the horizontal plane is in the range of 2° to 10°.

[0294] In order to further prevent the heat exchange condensed water in the second water receiving part 132 from passing through the second guide part 1332 and entering the connecting channel 109 from the first water inlet 832, the drain pipe 830 is provided with a blocking part 108. The blocking part 108 is located at the first water inlet 832 and at the upper edge of the first water inlet 832. On the one hand, the size of the first water inlet 832 can be reduced, thereby preventing the heat exchange condensed water from entering the connecting channel 109. On the other hand, the blocking part 108 interacts with the heat exchange condensed water to reduce the kinetic energy of the heat exchange condensed water, thereby making it difficult for the heat exchange condensed water to enter the connecting channel 109 from the first water inlet 832.

[0295] When the heat exchange condensed water in the second water receiving portion 132 passes through the second guide portion 1332 and enters the drain pipe 830 from the second water inlet 831, it is easy to impact the blocking portion 108 under the action of inertia, thereby reducing the kinetic energy of the heat exchange condensed water, and making it difficult for the heat exchange condensed water to enter the connecting channel 109 from the first water inlet 832.

[0296] In order to ensure that the fresh air condensed water in the drainage channel 811 can reliably flow into the drainage pipe 830, the opening size of the first water inlet 832 is usually at least 2 mm to prevent the first water inlet 832 from being blocked.

[0297] It should be noted that the drainage channel 811 is usually designed as a channel with an open top to facilitate cleaning of the drainage channel 811 .

[0298] In some embodiments, the outlet portion 810 is connected to a connecting piece 820, which is connected to the portion of the outlet portion 810 located outside the connecting channel 109 and is arranged close to one end of the outlet portion 810 close to the second water receiving piece 800 to close the drainage channel 811 to prevent the evaporation of fresh air condensation water.

[0299] In other embodiments, the connecting member 820 is detachably connected to the outlet portion 810, the outlet portion 810 is provided with a second clamping portion 812, the connecting member 820 is provided with a second connecting hole 821, and the second clamping portion 812 cooperates with the second connecting hole 821 to make the connecting member 820 detachably connected to the outlet portion 810.

[0300] The outlet portion 810 is provided with ribs 813, which are arranged in the drainage channel 811 and close to the second water receiving member 800. The ribs 813 include multiple ribs, and the multiple ribs 813 are staggered with each other. On the one hand, the ribs 813 can slow down the flow rate of fresh air condensation water in the drainage channel 811, and on the other hand, they can increase the connection strength between the outlet portion 810 and the connecting member 820.

[0301] To facilitate the drainage of fresh air condensation water and / or heat exchange condensation water through the drain pipe 830, the drain pipe 830 is typically tilted, i.e., the water inlet of the drain pipe 830 is higher than the water outlet of the drain pipe 830. In actual applications, the rear side of the housing 100 is typically positioned toward a wall, and the drain pipe 830 is installed outdoors through the wall. Therefore, it can be seen that the drain pipe 830 is tilted downward from the front side of the housing 100 toward the rear side of the housing 100.

[0302] It should be noted that the drain pipe 830 provided on the base 130 may be not long enough. In actual application, the drain pipe 830 may be connected to an additional pipeline to drain the condensed water outdoors. This is common knowledge in the art and will not be elaborated on.

[0303] The working principle of the wall-mounted air-conditioning indoor unit in this embodiment is as follows: through the operation of the fresh air fan, the outdoor fresh air enters the fresh air duct from the volute air inlet 602, is filtered by the filter component, and then enters the outlet duct from the volute air outlet 601 through the outlet portion 106, and then is output to the room from the second air outlet 103 through the fourth air outlet 501; the fresh air condensate generated when the outdoor fresh air is output to the room will drip from the drain outlet 504 to the water receiving channel 801 under the action of gravity, and the fresh air condensate dripping to the water receiving channel 801 passes through the drain channel 811 and enters the drain pipe 830 from the first water inlet 832, and the fresh air condensate is finally discharged to the outside through the drain pipe 830.

[0304] The heat exchange fan 300 is operated to introduce indoor air into the first inner cavity 104 through the first air inlet 101. After heat exchange through the heat exchanger 400 to form conditioned air, the conditioned air is output to the room through the first air outlet 102. The heat exchange condensed water generated by the conditioned air passing through the heat exchanger 400 will accumulate on the surface of the heat exchanger 400 and drip to the first water receiving part 131 and the second water receiving part 132 under the action of gravity. The heat exchange condensed water in the first water receiving part 131 passes through the first guide part 1331 under the action of gravity and enters the drain pipe from the second water inlet 831. 830. The heat exchange condensed water in the second water receiving part 132 passes through the second guide part 1332 under the action of gravity and enters the drain pipe 830 from the second water inlet 831. When the heat exchange condensed water in the second water receiving part 132 enters the drain pipe 830 from the second water inlet 831, it may impact the blocking part 108 under the action of inertia. After the heat exchange condensed water impacts the blocking part 108, the kinetic energy is weakened, and it is difficult for the heat exchange condensed water to enter the connecting channel 109 from the first water inlet 832, thereby flowing into the drain pipe 830. Finally, the heat exchange condensed water is discharged to the outside through the drain pipe 830.

[0305] The wall-mounted air-conditioning indoor unit in this embodiment is provided with a first water receiving member below the heat exchanger 400 to receive the heat exchange condensed water generated when the indoor air passes through the heat exchanger 400 for heat exchange; the first water receiving member is provided to include a first water receiving portion 131 and a second water receiving portion 132, so that the first water receiving member and the heat exchanger 400 structure cooperate to better receive the heat exchange condensed water generated when the indoor air passes through the heat exchanger 400 for heat exchange; a guide member 133 is provided, and a second water inlet 831 is provided at the connection between the guide member 133 and the drain pipe 830 to guide the heat exchange condensed water received by the first water receiving portion 131 and the heat exchange condensed water received by the second water receiving portion 132 to flow from the second water inlet 831 into the same drain pipe 830; a fresh air member 500 is provided, and an air outlet duct is defined inside the fresh air member 500, and the air outlet duct inside the fresh air member 500 is used to connect the fresh air duct inside the fresh air volute 600 with the second air outlet 1 03; By setting a fourth air outlet 501 on the fresh air member 500, and utilizing the fourth air outlet 501 to extend along the length direction of the casing 100 and to be arranged corresponding to the second air outlet 103, the air outlet range of the outdoor fresh air is increased; by setting a second water receiving member 800, and providing a drain outlet 504 on the fresh air member 500, so that the second water receiving member 800 can receive the fresh air condensation water generated when the outdoor fresh air is output to the indoor, so as to prevent the fresh air condensation water from damaging other components of the air-conditioning indoor unit; by setting a lead-out portion 810, utilizing the lead-out portion 810 to guide the fresh air condensation water to the drain pipe 830; by providing a connecting portion on the casing 100, so that the lead-out portion 810 can discharge the fresh air condensation water into the drain pipe 830 through the connecting portion; by providing a first water inlet 832 on the drain pipe 830, utilizing the first water inlet 832 to be connected with the connecting portion and the lead-out portion 810, so that the fresh air condensation can be discharged from the first water inlet 832 to the drain pipe 830.

[0306] In the wall-mounted air-conditioning indoor unit of this embodiment, the heat exchange condensed water and the fresh air condensed water are discharged to the outside through the same drain pipe 830.
