Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a wall-mounted air conditioning indoor unit. Background Art

[0002] Fresh air air conditioner is a healthy and comfortable air conditioner with fresh air function. In addition to the temperature control function of traditional air conditioner heating or cooling, it also adds a fresh air system to purify outdoor oxygen-rich air and introduce it into the room, thereby realizing the function of circulation and ventilation between indoor and outdoor air.

[0003] 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 to the room through different air outlets, wherein outdoor fresh air is output to the room through the second air outlet, and air-conditioned air is output to 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 direction of the casing with the first air outlet. Since the first air outlet extends along the length direction of the casing, the opening size of the second air outlet is smaller, and the diffusion range of outdoor fresh air in the room is smaller. The second air outlet is distributed along the length direction of the casing with the first air outlet, and the outdoor fresh air and air-conditioned air are discharged relatively independently. The degree of mixing of outdoor fresh air and air-conditioned air is low. When the temperature difference between outdoor fresh air and air-conditioned air is large, two winds of different temperatures blow toward the user, which is easy to cause user discomfort and reduce user experience.

[0004] In view of this, this application is filed. Utility Model Content

An air guide plate 200 is provided at the first air outlet 102, and the air guide plate 200 is connected to the housing 100 in an openable and closable manner to open or close the first air outlet 102.

[0150] like Figure 6 and Figure 7 As shown, the heat exchanger 400 is installed in the housing 100 and is located in the first inner cavity 104. After the air in the first inner cavity 104 contacts the heat exchanger 400, it is heat-exchanged by the heat exchanger 400 to form air-conditioned air to meet the cooling or heating needs of the user; it should be noted that the heat exchanger 400 is arranged close to the first air inlet 101. It should also be noted that the air-conditioned air can be cold air, hot air, or even normal temperature air.

[0151] like Figure 6 and Figure 7As shown, the heat exchange fan 300 is installed in the housing 100 and is located in the first inner cavity 104, and the heat exchange fan 300 is located below the heat exchanger 400. The axial direction of the heat exchange fan 300 extends along the length direction of the housing 100. Through the operation of the heat exchange fan 300, indoor air is introduced into the first inner cavity 104 from the first air inlet 101, and after heat exchange in the heat exchanger 400 to form conditioned air, the conditioned air flows into the room from the first air outlet 102. It should be noted that the heat exchange fan 300 is a cross-flow fan.

[0152] The fresh air module is used 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.

[0153] 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 a 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, and 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.

[0154] like Figure 7 and Fig.13 As shown, 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 .

[0155] 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.

[0156] 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.

[0157] like Fig.10 and Fig.11 As shown, the fresh air volute 600 includes a first volute 610, a second volute 620 and a fresh air case 630; the first volute 610 and the second volute 620 are arranged opposite to each other and together form a fresh air cavity, and the fresh air fan is installed in the fresh air cavity; the fresh air case 630 and the side of the second volute 620 away from the first volute 610 are arranged opposite to each other to 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, it is convenient to install the fresh air fan in the fresh air cavity.

[0158] 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 used 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.

[0159] 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 users to disassemble the purification module 700. The disassembly and installation method of the purification module 700 is simple and easy to operate.

[0160] like Figure 5 As shown, the rear shell 120 also includes a second socket 107, and the second socket 107 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.

[0161] The fresh air fan is a centrifugal fan, which is used to introduce indoor fresh air into the room; the fresh air fan is installed in the fresh air chamber, 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 chamber, passes through the volute air outlet 601, and flows into the room from the second air outlet 103.

[0162] It should be noted that the axial direction of the fresh air fan is arranged along the length direction of the housing 100, so that the outdoor fresh air flows in a direction intersecting with the length direction of the housing 100 after passing through the fresh air fan. The opening direction of the volute air outlet 601 is usually designed to be a direction intersecting with the length direction of the housing 100, and the purpose is to facilitate the outdoor fresh air to flow out of the fresh air cavity through the volute air outlet 601.

[0163] like Figure 2 and Figure 3 As shown, the second air outlet 103 extends along the length direction of the housing 100 so that the second air outlet 103 is in a long 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.

[0164] 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 casing 100 in the length direction, 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 corresponding to the second air outlet 103. Therefore, in this embodiment, a fresh air piece 500 is provided, 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 with 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 from the second air outlet 103 to the room through the fresh air piece 500.

[0165] Specifically, Figure 8 and Fig. 9 As shown, 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, which extends along the length direction of the casing 100 and is connected to the fresh air duct inside the fresh air volute 600.

[0166] 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 with 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 with 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.

[0167] like Fig.13 As shown, a connecting port 503 is provided at one end of the fresh air piece 500 connected to the fresh air volute 600, and the connecting port 503 is arranged corresponding to the volute air outlet 601, so that the air outlet duct inside the fresh air piece 500 is connected with the fresh air duct inside the fresh air volute 600.

[0168] 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.

[0169] In some embodiments, the fresh air member 500 is installed between the front side plate 110 and the rear shell 120. The front side plate 110 and the rear shell 120 are arranged opposite to each other in a horizontal plane and define a receiving cavity together. The receiving cavity is located in front of the first inner cavity 104 and the second inner cavity 105. The fresh air member 500 is arranged in the receiving cavity. Since the fresh air member 500 is installed between the front side plate 110 and the rear shell 120, it can be known that the fresh air member 500 is arranged outside the rear shell 120, which means that the fresh air member 500 is arranged outside the second inner cavity 105.

[0170] Since the fresh air volute 600 is located in the second inner cavity 105, and the fresh air member 500 is arranged outside the second inner cavity 105 (that is, the fresh air member 500 is arranged in the accommodating cavity 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 member 500, as shown in FIG. Figure 5 As shown, the rear shell 120 is provided with a through-portion 106, and the volute air outlet 601 and the connecting port 503 are respectively arranged corresponding to the through-portion 106, so that the outdoor fresh air in the fresh air volute 600 can enter the air outlet duct from the volute air outlet 601 through the through-portion 106 and the connecting port 503.

[0171] 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 along a direction intersecting with the length direction of the casing 100 after being acted upon by the fresh air fan, the outdoor fresh air needs to change direction when entering the outlet air 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 air duct. Therefore, the fresh air volute 600 is provided with a connecting portion 640, which is connected to the fresh air component 500, and the connecting portion 640 is used to achieve the transition of the direction of the outdoor fresh air. The volute air outlet 601 is opened in the connecting portion 640, and the opening direction of the volute air outlet 601 is set along the length direction of the casing 100.

[0172] 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.

[0173] 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, 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 on the outside of 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 arranged on the outside of the second inner cavity 105 through the through-hole 106.

[0174] like Figure 14-Figure 20 As shown, 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, and the air guide portion 530 divides the air outlet duct into multiple air outlet branches 540, and each air outlet branch 540 is correspondingly provided with a branch air outlet, and 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.

[0175] The wall-mounted air-conditioning indoor unit provided in the present application 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 the 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 in 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 extend respectively 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.

[0176] 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.

[0177] The fresh air component 500 includes a first sub-component 510 and a second sub-component 520, and the first sub-component 510 and the second sub-component 520 extend along the length direction of the casing 100 respectively. The first sub-component 510 is arranged toward the front side plate 110 of the casing 100, and the second sub-component 520 is arranged toward the heat exchanger 400. The first sub-component 510 and the second sub-component 520 are relatively arranged 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 sub-component 510 and the second sub-component 520.

[0178] 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 edges of the bending portion 560, the extension portion 550 and 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.

[0179] It should be noted that the length of the first sub-component 510 exceeds the length of the second sub-component 520 .

[0180] 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 transport the outdoor fresh air to the user's vicinity 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.

[0181] However, the second air outlet 103 is opened on the side of the casing 100 facing the user, which may cause 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 the 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 is also easy to enter the casing 100 through the second air outlet 103.

[0182] 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 modes.

[0183] Figure 1-Figure 25 This is a specific implementation of the wall-mounted air conditioner indoor unit of the present application. 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.

[0184] Since the second air outlet 103 is opened at 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.

[0185] Specifically, 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.

[0186] 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 indoor transmission distance of outdoor fresh air is usually smaller than the indoor transmission distance of air-conditioning air. After the outdoor fresh air is mixed with the air-conditioning air, the outdoor fresh air can be transported indoors over a longer distance with the help of the air-conditioning air.

[0187] 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 correspondingly 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.

[0188] 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 arranged 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.

[0189] Specifically, when the air guide plate 200 opens the first air outlet 102, the second air outlet 103 is opened at the same time; when the air guide plate 200 closes the first air outlet 102, the second air outlet 103 is closed at the same time. By controlling the opening and closing states of the second air outlet 103 and the first air outlet 102 through the same air guide plate 200, the air guide plate 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 indoor unit of the air conditioner is not working. This setting method can realize the control of the opening and closing state of the second air outlet 103 without adding other components; there is no need to set up additional components to open or close the second air outlet 103 separately, thereby simplifying the overall structure.

[0190] like Fig.21As shown, by the operation of the fresh air fan, 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.

[0191] It should be noted that when outdoor fresh air is output to the indoor through the second air outlet 103 , no matter whether the air conditioner indoor unit performs heat exchange or not, the air guide plate 200 needs to rotate to open the second air outlet 103 .

[0192] 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 herein.

[0193] Since the air outlet duct extends along the length direction of the housing 100, and the opening direction of the volute air outlet 601 is set toward the front side of the housing 100, it can be known that the outdoor fresh air needs to change its flow direction at least once when entering the air outlet duct from the fresh air duct. Therefore, in order to facilitate the connection between the air outlet duct and the fresh air duct, the first sub-component 510 and the second sub-component 520 jointly define a transition cavity, which includes an opening set along the length direction of the housing 100 and an opening set toward the rear side of the housing 100, wherein the transition cavity is connected to the air outlet duct through the opening of the transition cavity set along the length direction of the housing 100, and the transition cavity is connected to the volute air outlet 601 through the opening of the transition cavity set toward the rear side of the housing 100.

[0194] The working principle of the wall-mounted air conditioner indoor unit in this embodiment when the fresh air and heat exchange functions are turned on is as follows: the air guide plate 200 opens the second air outlet 103 and the first air outlet 102, and the fresh air fan is operated to introduce the outdoor fresh air into the fresh air duct from the volute air inlet 602 and enter the air outlet duct from the volute air outlet 601 through the outlet portion 106, and the outdoor fresh air is output to the room from the second air outlet 103 through the fourth air outlet 501; 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 in the heat exchanger 400 to form air conditioning air, the air conditioning air is output to the room from the first air outlet 102. 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 conditioning air output to the room from the first air outlet 102, thereby reducing the temperature difference between the outdoor fresh air and the air conditioning air, thereby reducing the discomfort caused by the user being exposed to two airs with large temperature differences.

[0195] It should be noted that when it is necessary to introduce outdoor fresh air, the air 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 air guide plate 200 needs to open the first air outlet 102, and the air 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 air guide plate 200 will close the first air outlet 102 and the second air outlet 103.

[0196] The wall-mounted air-conditioning indoor unit provided in the present 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 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.

[0197] 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 conditioned air, thereby reducing the user's discomfort caused by being exposed to two airs with a large temperature difference.

[0198] Figure 26-Figure 33 This is another specific implementation of the wall-mounted air conditioner indoor unit of the present application. In this embodiment, the second air outlet 103 is opened on the front side of the casing 100, and the wall-mounted air conditioner indoor unit also includes a rotating member 140, which is arranged at the second air outlet 103.

[0199] Specifically, Fig.28 As shown, 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, thereby reducing the user's discomfort caused by being exposed to two airs with a large temperature difference.

[0200] It should be noted that, in order to cooperate with the second air outlet 103, the fourth air outlet 501 is also correspondingly 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 outdoor fresh air.

[0201] 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.

[0202] Although opening the second air outlet 103 on the front side panel 110 can increase the visualization effect of outdoor fresh air to a certain extent, 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 relatively poor.

[0203] In order to further increase the visualization effect of outdoor fresh air, such as Fig.26 As shown, a rotating member 140 is provided at the second air outlet 103, and 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. Since the outdoor fresh air has kinetic energy, the outdoor fresh air will drive 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 rotating the rotating member 140. It should be noted that the rotating member 140 protrudes from the side of the front side plate 110 away from the rear housing 120, so that the user can clearly see the rotation of the rotating member 140.

[0204] In some embodiments, the rotating member 140 has a spiral structure, and the rotating member 140 defines a spiral channel, which is located at the periphery of the rotating member 140 and is connected to the air outlet duct and the indoor room respectively; the spiral channel is used 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 onto the user.

[0205] It should be noted that the rotating member 140 includes a plurality of spiral channels, and the plurality of spiral channels 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.

[0206] like Fig.32As shown, the rotating member 140 includes a plurality of helical segments 143, which are distributed along the length direction of the housing 100. Two adjacent helical segments 143 are connected end to end along the length direction of the housing 100, and the helical segments 143 have the same helical angle, so that the rotating member 140 is twisted along its axis at the same helical angle.

[0207] In some embodiments, the helical angle of the rotating member 140 ranges from 20° to 90°.

[0208] like Fig.33 As shown, the spiral section 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 .

[0209] In some embodiments, the first center line 141 and the second center line 142 are disposed perpendicular to each other.

[0210] In some embodiments, the distance L between the first center lines 141 of two adjacent spiral segments 143 has a value in the range of 30 mm to 120 mm.

[0211] 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 axis of the plate material at a certain spiral angle.

[0212] The spiral section 143 includes an edge arranged along the length direction of the housing 100, and the maximum value of the thickness dimension of the edge is the thickness dimension at the center of the spiral section 143. The edge is the side of the spiral section 143, and the center of the spiral section 143 is the middle part of the spiral section 143.

[0213] The thickness of the spiral node 143 decreases gradually from its center along the first center line 141 toward the edge. By designing the spiral node 143 to be thin on both sides and thick in the middle, not only the weight of the spiral node 143 can be reduced, but also the manufacturing material of the spiral node 143 can be conveniently twisted to form the spiral node 143 during the manufacturing process of the spiral node 143.

[0214] 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°.

[0215] In practice, the material of the rotating part 140 is first demolded to make the long strip of plate 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.

[0216] In some embodiments, the draft angle of the long strip plate ranges from 05° to 2°.

[0217] In practical applications, the surface of the rotating member 140 may be designed to be an eye-catching color such as bright yellow to further enhance the visualization effect of the outdoor fresh air.

[0218] The working principle of the wall-mounted air conditioner indoor unit in this embodiment is as follows: the outdoor fresh air is introduced into the fresh air duct from the volute air inlet 602 through the operation of the fresh air fan, and enters the air outlet duct from the volute air outlet 601 through the outlet portion 106, and finally, the outdoor fresh air is output to the room from the second air outlet 103 through the fourth air outlet 501. When the outdoor fresh air is output to the room from the second air outlet 103, the outdoor fresh air will pass through the rotating member 140, and when the outdoor fresh air passes through the rotating member 140, the outdoor fresh air will drive the rotating member 140 to rotate, so as to increase the visualization effect of the outdoor fresh air; at the same time, the outdoor fresh air is also dispersed and diverted by the rotating member 140, so as to prevent the outdoor fresh air from blowing directly to the user.

[0219] The wall-mounted air-conditioning indoor unit in this embodiment is provided with a rotating member 140 at the second air outlet 103, so that when the outdoor fresh air passes through the rotating member 140, the outdoor fresh air drives the rotating member 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 member 140, the rotating member 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 member 140 as a spiral structure, not only can the outdoor fresh air drive the rotating member 140 to rotate conveniently, but also the spiral channel of the rotating member 140 can guide the flow of the outdoor fresh air and divert the outdoor fresh air.

[0220] 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.

[0221] Figure 34-Figure 49 This is a specific implementation of the wall-mounted air conditioner indoor unit of the present application. In this embodiment, the second air outlet 103 is opened at the front side of the housing 100 .

[0222] 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 from the second air outlet 103, and the air-conditioned air is output to the room from the first air outlet 102, the user will be exposed to two airs with large temperature differences, which may easily cause physical discomfort and reduce the user experience. Therefore, in this embodiment, by opening the fifth air outlet 502 in the fresh air part 500, the air outlet duct is connected with the first inner cavity 104 through the fifth air outlet 502, so that the outdoor fresh air in the air outlet duct can enter the first inner cavity 104 and contact the heat exchanger 400, and the outdoor fresh air is heat-exchanged by the heat exchanger 400 to form air-conditioned air, so as to reduce the temperature difference between the outdoor fresh air and the air-conditioned air, and the outdoor fresh air that is heat-exchanged to form air-conditioned air is also output to the room from the first air outlet 102.

[0223] It should be noted that the second air outlet 103 is opened on the front side plate 110 , and the fourth air outlet 501 is also correspondingly opened on the side of the fresh air component 500 facing the front side plate 110 of the casing 100 , so that the fourth air outlet 501 and the second air outlet 103 are arranged correspondingly.

[0224] 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 plate 110 to prevent dust and the like from entering the fresh air duct through the second air outlet 103 .

[0225] like Fig.39 As shown, by operating 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 first inner cavity 104 through the fifth air outlet 502 through the air outlet duct. By operating 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 through the first air outlet 102.

[0226] Since the outdoor fresh air is heated and then formed into conditioned air and then outputted indoors through the first air outlet 102, the user is only exposed to the conditioned air, thereby avoiding the user's discomfort caused by being exposed to two airs of different temperatures at the same time. It should be noted that the fifth air outlet 502 is provided on the side of the fresh air member 500 facing the heat exchanger 400, so that the outdoor fresh air in the air outlet duct passes through the fifth air outlet 502 and enters the first inner cavity 104; wherein, the branch air outlet is also connected to the fifth air outlet 502.

[0227] The fifth air outlet 502 also extends along the length direction of the housing 100 to increase the efficiency of outputting outdoor fresh air in the air outlet duct to the first inner cavity 104 .

[0228] Since the fresh air component 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 outlet of outdoor fresh air in the air outlet duct. Therefore, the present 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 used to make the air outlet duct selectively connected to the second air outlet 103 or the first inner cavity 104.

[0229] 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 operates to introduce the outdoor fresh air into the fresh air duct through 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 introduce the indoor air into the first inner cavity 104 through 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 through the first air outlet 102.

[0230] When the temperature difference between the outdoor fresh air and the air-conditioned 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 operates 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 operates to introduce the indoor air into the first inner cavity 104 through the first air inlet 101, and after heat exchange by the heat exchanger 400 to form air-conditioned air, the air-conditioned air is output to the room through the first air outlet 102.

[0231] 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, and when the switching component 900 opens the fourth air outlet 501, the fifth air outlet 502 is closed.

[0232] Specifically, Fig.48 As shown, 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 rotating axis 920 of the rotating shaft 920 is arranged along the length direction of the housing 100, and the rotating shaft 920 is connected to a driving member, which is used 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 is correspondingly arranged to the fifth air outlet 502, 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.

[0233] 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 provided in 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 can be facilitated, but also the installation of the switching component 900 can be facilitated.

[0234] When the temperature difference between the outdoor fresh air and the air-conditioned 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 from the fourth air outlet 501 to the second air outlet 103.

[0235] At this time, the outdoor fresh air does not undergo heat exchange processing in the heat exchanger 400, and the outdoor fresh air and the air-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 air-conditioned air is small at this time, even if the user is exposed to the outdoor fresh air and the air-conditioned air at the same time, the discomfort caused by the temperature difference is also weak. It should be noted that at this time, the outdoor fresh air does not pass through the first air outlet 102, so the air guide plate 200 can close the first air outlet 102.

[0236] When the temperature difference between the outdoor fresh air and the air-conditioned 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. 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 air outlet duct, and is output from the fifth air outlet 502 to the first inner cavity 104. 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 by the heat exchanger 400 to form air-conditioned air, and then the air-conditioned air is output from the first air outlet 102 to the room.

[0237] At this time, the outdoor fresh air is heat exchanged by the heat exchanger 400 to form air-conditioned air. Since the indoor air is also heat exchanged 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 temperature of 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. Only air-conditioned air of one temperature is output to the room, thereby avoiding the user's discomfort caused by being exposed to two winds with a large temperature difference.

[0238] 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.

[0239] It should also be noted that, without closing the first air inlet 101, 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, and the outdoor fresh air and indoor air may mix in the first inner cavity 104 to form mixed wind.

[0240] 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.

[0241] 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.

[0242] 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 used to detect the outdoor temperature and the air-conditioning wind temperature, so as to obtain the temperature difference between the outdoor fresh air and the air-conditioning wind. The controller controls the operation of the driving component according to the temperature difference obtained by the temperature detection component, so as to control the air outlet mode of the outdoor fresh air.

[0243] In some embodiments, the temperature detection component includes an outdoor temperature sensor and an indoor temperature sensor. The outdoor temperature sensor is used to detect the outdoor temperature, and the indoor temperature sensor is used 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.

[0244] It should be noted that the user can automatically control the operation of the switching component 900 according to the detection result of the temperature detection component, or manually control the operation of the switching component 900 according to 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 according to personal preferences and habits.

[0245] The working principle of the wall-mounted air conditioner indoor unit 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, so that the baffle 910 closes the fourth air outlet 501 and opens the fifth air outlet 502. The outdoor fresh air is introduced into the fresh air duct from the volute air inlet 602 through the air outlet duct and output from the fifth air outlet 502 to the first inner cavity 104; the indoor air is introduced into the first inner cavity 104 from the first air inlet 101 through the heat exchange fan 300, and the outdoor fresh air and indoor air in the first inner cavity 104 are in contact with the heat exchanger 400, and the outdoor fresh air and indoor air are heat exchanged through the heat exchanger 400 to form conditioned air, which is output to the room from the first air outlet 102. At this time, the outdoor fresh air is mixed with the indoor air and heat exchanged through the heat exchanger 400 to form conditioned air, so that the user is only exposed to conditioned air of one temperature, thereby avoiding the user's discomfort caused by being exposed to two kinds of wind with a large temperature difference.

[0246] 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. The fresh air fan is operated to introduce the outdoor fresh air from the volute air inlet 602 into the fresh air duct through the air outlet duct from the fourth air outlet 501 through the second air outlet 103 to the indoor room; the heat exchange fan 300 is operated to introduce the indoor air from the first air inlet 101 into the first inner cavity 104, and after heat exchange in the heat exchanger 400 to form air-conditioning air, the air-conditioning air is output to the indoor room from the first air outlet 102. At this time, the outdoor fresh air does not undergo heat exchange processing in the heat exchanger 400, and the outdoor fresh air and the air-conditioning air are independently discharged and output to the indoor room from different air outlets. Since the temperature difference between the outdoor fresh air and the air-conditioning air is small at this time, even if the user is exposed to the outdoor fresh air and the air-conditioning air at the same time, the discomfort caused by the temperature difference is also weak.

[0247] The wall-mounted air conditioner indoor unit of this embodiment is provided with a fifth air outlet 502 in the fresh air element 500, and the fifth air outlet 502 is connected with 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 heat-exchanged 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 having a strong discomfort due to being exposed to two kinds of air with a large temperature difference. By setting a switching component 900, the fourth air outlet 501 is opened or closed and the fifth air outlet 502 is opened or closed by using the switching component 900, so that the outdoor fresh air in the air outlet duct can choose the air outlet mode and can be reliably discharged under a certain air 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.

[0248] In the wall-mounted air-conditioning indoor unit of the present 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, when the outdoor fresh air is blown into the room after heat exchange, the mixing effect with the indoor air is good, 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.

[0249] Figure 50-Figure 63 This is another specific implementation of the wall-mounted air conditioner indoor unit of the present application. In this embodiment, the opening of the second air outlet 103 faces upward and is arranged close to the first air inlet 101.

[0250] 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 indoor 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 contacts the heat exchanger 400 under the action of the operation of the heat exchange fan 300 and is heat exchanged by the heat exchanger 400 to form air-conditioned air, and the air-conditioned air is output to the indoor room from the first air outlet 102.

[0251] Outdoor fresh air is introduced into the first inner cavity 104 and heat-exchanged by the heat exchanger 400 to form conditioned air, thereby reducing the discomfort caused by the user being exposed to two airs with a large temperature difference.

[0252] 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.

[0253] In some embodiments, the opening of the second air outlet 103 is set upward, which can shorten the distance between the second air outlet 103 and the first air inlet 101, increase the speed of outdoor fresh air entering the first inner cavity 104, and prevent the outdoor fresh air from blowing directly to the user when the fresh air is turned on alone, causing discomfort to the user. It should be noted that the second air outlet 103 is defined by the front side plate 110 and the rear shell 120; it should also be noted that the fourth air outlet 501 is also correspondingly opened at the top of the fresh air member 500 and is set with the opening upward, so that the fourth air outlet 501 is set corresponding to the second air outlet 103.

[0254] 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 when the outdoor fresh air is output to the room after heat exchange by the heat exchanger 400. It should be noted that although the air-conditioned air is not output in the air-conditioned room at this time, the user is also exposed to two airs of different temperatures, namely the outdoor fresh air and the indoor air.

[0255] The operation of the heat exchange fan 300 causes the indoor air to enter the first inner cavity 104 from the first air inlet 101, which means that when the outdoor fresh air enters the first inner cavity 104 and contacts the heat exchanger 400 for heat exchange, the indoor air will also enter the first inner cavity 104 from the first air inlet 101. At the same time, since the second air outlet 103 is arranged close to 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 from the first air outlet 102.

[0256] It should be noted that the outdoor fresh air and the indoor air are usually mixed in the first inner cavity 104 to form a mixed wind, and the mixed wind is heat exchanged to form air-conditioned wind and then output to the room through the first air outlet 102. Therefore, in the air outlet mode in which the outdoor fresh air is heat exchanged by the heat exchanger 400 and then output to the room, the mixing effect of the outdoor fresh air and the indoor air is good. It should also be noted that since the force of the heat exchange fan 300 on the air is usually greater than the force of the fresh air fan on the air, the indoor conveying distance of the outdoor fresh air in this air outlet mode is longer than the indoor conveying distance of the outdoor fresh air directly output from the second air outlet 103 to the room.

[0257] The outlet modes of outdoor fresh air in the wall-mounted air conditioner indoor unit in this embodiment include outdoor fresh air being directly output to the indoor through the second air outlet 103 , and outdoor fresh air being heat exchanged by the heat exchanger 400 to form air-conditioned air and then output to the indoor through the first air outlet 102 .

[0258] In the air outlet mode in which the outdoor fresh air is directly outputted to the indoor room from the second air outlet 103, the outdoor fresh air does not enter the first inner cavity 104 and contact the heat exchanger 400, and the outdoor fresh air flows under the action of the fresh air fan, so the heat exchange fan 300 is not involved in the output process of the outdoor fresh air; and, since the outdoor fresh air is outputted to the indoor room from the second air outlet 103, the air guide plate 200 and the first air outlet 102 are not involved in the output process of the outdoor fresh air. This air outlet mode can realize the air conditioner indoor unit to start the fresh air separately, and this air outlet mode is simple to discharge and saves energy.

[0259] 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 through the first air outlet 102, the outdoor fresh air is first output to the indoor 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 will also be 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. Moreover, since the outdoor fresh air is heated to form air-conditioned air and then output to the indoor 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.

[0260] It should be noted that since the second air outlet 103 is connected to the indoor room, 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 room 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 room from the second air outlet 103 at a long distance from the user. During the diffusion process in the indoor room, 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 room from the second air outlet 103 comes into contact with the user, the user's discomfort is less caused.

[0261] The outdoor fresh air and the indoor air may be mixed in the first inner cavity 104, or they may be separately 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 belongs to the common knowledge technology in the field and will not be repeated here.

[0262] 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.

[0263] The second sub-component 520 further includes a sixth air inlet 506 , which is disposed at the connection between the fresh air component 500 and the fresh air volute 600 , so that the fresh air duct inside the fresh air volute 600 is connected to the air outlet duct inside the fresh air component 500 .

[0264] The fresh air component 500 is designed as a split structure, which can facilitate the installation and disassembly of the fresh air component 500 on the one hand, and can also facilitate the cleaning of the first subcomponent 510 on the other hand. Since the openings of the second air outlet 103 and the fourth air outlet 501 are arranged upward, dust and the like can easily enter the air outlet duct from the second air outlet 103 through the fourth air outlet 501, so the first subcomponent 510 needs to be cleaned regularly, while the second subcomponent 520 does not have the fourth air outlet 501, and the outdoor fresh air is output from the inside of the second subcomponent 520 to the inside of the first subcomponent 510, so the dust and the like falling into the inside of the first subcomponent 510 is not easy to enter the second subcomponent 520, and the cleaning frequency of the second subcomponent 520 is usually lower than that of the first subcomponent 510.

[0265] 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, but 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.

[0266] When fresh air and air-conditioning air are turned on at the same time, both the heat exchange fan 300 and the fresh air fan are working. Through the operation of the fresh air fan, outdoor fresh air is introduced into the fresh air duct through the volute air inlet 602, passes through the volute air outlet 601 and the outlet part 106, and enters the air outlet duct. 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 from 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.

[0267] 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.

[0268] 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, the heat exchange fan 300 and the fresh air fan can also 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 outdoor fresh air with a large temperature difference from the indoor temperature.

[0269] 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 heat-exchanged 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.

[0270] The wall-mounted air-conditioning indoor unit in the present 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 in 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 the present 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.

[0271] Figure 64-Figure 71 This is another specific implementation of the wall-mounted air-conditioning indoor unit of the present application. In this embodiment, the wall-mounted air-conditioning indoor unit also includes an air guide portion 530 .

[0272] like Fig.67 As shown, 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 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.

[0273] Since the fresh air piece 500 is located on the front side 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 together 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 wind.

[0274] It should be noted that the fresh air member 500 is arranged opposite to the first section 410, and the interval 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 arranged toward the fresh air member 500 and is used to define and form the channel 160.

[0275] 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.

[0276] In order to install the fresh air component 500 inside the casing 100 without changing the dimension of the casing 100 in the thickness direction, the distance between the fresh air component 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 component 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.

[0277] 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 installation of the fresh air component 500 inside the casing 100 without changing the size of the casing 100 in the thickness direction.

[0278] 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 to enter the channel 160 to contact and exchange heat with the first section 410, thereby reducing the influence of the fresh air piece 500 on the heat exchange effect of the heat exchanger 400.

[0279] Specifically, the air guide portion 530 is arranged 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.

[0280] It should be noted that the air guide portion 530 makes the dimension of the upper end of the fresh air member 500 along the thickness of the casing 100 smaller than the dimension of the lower end of the fresh air member 500 along the thickness of the casing 100 .

[0281] 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, wherein the minimum value of the L value range is L.

[0282] 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 passage 160 is roughly trumpet-shaped along the thickness direction of the housing 100 , thereby increasing the amount of air introduced into the passage 160 by the air guide 530 .

[0283] In some embodiments, L1 is 20 mm and L2 is 17 mm.

[0284] Since the air guide portion 530 is located on the side of the fresh air member 500 facing the channel 160 , it can be known that the air guide portion 530 is also used to define the channel 160 together with the fresh air member 500 , the first section 410 and the casing 100 .

[0285] 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 .

[0286] 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 interconnected; the first part 1601 is defined by the wind guide portion 530 and the first section 410; the second part 1602 is defined by the second side surface 505 and the first section 410; wherein the top opening of the channel 160 is defined by the wind guide portion 530 and the first section 410 and is interconnected with the first part 1601.

[0287] 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.

[0288] 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 satisfy 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.

[0289] like Fig.68 As shown, 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 .

[0290] The projection of the end of the air guide portion 530 toward the bottom of the housing 100 in 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

[0291] 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 can not only enable the air guide part 530 to better guide the air into the channel 160, but also enable the fresh air component 500 to better output outdoor fresh air to the room.

[0292] 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.

[0293] In some embodiments, the projection position of the bottom of the air guiding portion 530 within the first side surface 401 is located within an interval defined by the first dividing line 402 and the second dividing line 403 .

[0294] 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 .

[0295] like Figure 70-Figure 71 As shown, 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.

[0296] 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 can enter the first part 1601, and 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.

[0297] 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 air guiding effect. The provision of 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.

[0298] In some embodiments, the straight line segment 531 and the first side surface 401 are disposed parallel to each other along the height direction of the housing 100 .

[0299] In some other embodiments, the straight section 531 is disposed beyond the first section 410 along the height direction of the housing 100 , so that more air in the first inner cavity 104 can enter the channel 160 .

[0300] like Fig.69 As shown, the distance from the connection between the transition section 532 and the straight section 531 to the bottom of the fresh air member 500 along the height direction of the housing 100 is H, and the distance from the first side surface 401 along the height direction of the housing 100 is h, wherein h and H satisfy the relationship:

[0301] By making h and H satisfy the relationship: The transition section 532 can better guide the air to flow into the second portion 1602.

[0302] It should be noted that, in some embodiments, the distance of the first side surface 401 along the height direction of the housing 100 is considered to be the distance of the first section 410 along the height direction of the housing 100 .

[0303] By setting the straight line 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 of the fresh air piece 500 to the thicker size of the lower part of the fresh air piece 500 can be achieved, thereby ensuring the outdoor fresh air outlet effect.

[0304] In some embodiments, Fig.69 As shown, the transition section 532 is an arc section with a radius dimension R.

[0305] The distance between one end of the transition section 532 away from the straight section 531 and one end of the straight section 531 toward the top of the housing 100 along the thickness direction of the housing 100 is a, wherein a and R satisfy the relationship: 8<R / a<50.

[0306] The shape of the transition section 532 directly affects the air drainage effect of the transition section 532 . Therefore, by making a and R satisfy the relationship: 8<R / a<50, the transition section 532 can have a better air drainage effect.

[0307] 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, the air guide part 530 is provided to guide the air to contact the heat exchanger 400, so that the heat exchange effect of the heat exchanger 400 is less affected, and the impact on the air output volume of the air conditioning is also less.

[0308] 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 through 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 the air is introduced into the second part 1602 through the transition section 532, so that the air in the channel 160 contacts with the first section 410 for heat exchange and forms air-conditioned wind, which is output to the room through the first air outlet 102.

[0309] 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 to the indoor by the first air outlet 102 when it is outputted to the indoor, thereby reducing the 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 to the indoor from the second air outlet 103 through the air outlet duct; A fourth air outlet 501 is arranged, and the fourth air outlet 501 is arranged 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 outdoor fresh air can be output from the second air outlet 103 to the indoor through the fourth air outlet 501; the fresh air component 500 is arranged in the casing 100 to ensure the overall appearance of the air conditioner indoor unit; by arranging the air guide portion 530, not only can the opening size of the connection between the channel 160 and the first inner cavity 104 be increased to allow more air to enter the channel 160, but the air guide portion 530 can also 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.

[0310] In the wall-mounted air-conditioning indoor unit of the present 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 a 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 conditioner.

[0311] Since condensed water is easily generated when air exchanges heat with the heat exchanger 400, Figure 72-Figure 88 As shown, the wall-mounted air conditioner indoor unit also includes a first water receiving member, which is located in the first inner cavity 104 and is arranged below the heat exchanger 400, for receiving condensed water generated by air heat exchange. It should be noted that for the convenience of description, the condensed water generated during the air heat exchange process is referred to as heat exchange condensed water.

[0312] 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 for draining the heat exchange condensed water outdoors.

[0313] 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 along the length direction of the casing 100 respectively; 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 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.

[0314] 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, wherein 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.

[0315] 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.

[0316] The first water receiving member is integrally provided with the base 130 to simplify the overall structure and facilitate production.

[0317] 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, and the guide member 133 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, and 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.

[0318] 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 slope 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 slope in a downward inclined path, so that the heat exchange condensate water can better pass through the guide member 133 and flow into the drain pipe 830.

[0319] Specifically, 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, 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.

[0320] The first guide portion 1331 is 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 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.

[0321] 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 height of the guide member 133 is the smallest. 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.

[0322] 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 correspondingly opened on the side of the fresh air component 500 facing the front side plate 110 of the casing 100, so that the fourth air outlet 501 and the second air outlet 103 are correspondingly arranged.

[0323] Since condensation water is easily generated due to the temperature difference between indoor and outdoor during the process of outdoor fresh air being output to the room, and since the second air outlet 103 is provided on the front side plate 110 and extends along the length direction of the housing 100, and the fresh air member 500 is provided between the front side plate 110 and the rear housing 120, condensation water enters the rear housing 120, and it is easy to damage the components installed inside the rear housing 120. In this embodiment, the second water receiving member 800 is provided to receive the condensation water generated during the process of outdoor fresh air being output to the room. For the convenience of description, the condensation water generated by the outdoor fresh air is referred to as fresh air condensation water.

[0324] Specifically, Fig.83 As shown, a drain port 504 is provided at the bottom of the fresh air member 500 , and the drain port 504 is connected to the air outlet duct. The second water receiving member 800 is arranged corresponding to the drain port 504 so that the fresh air condensed water flows from the drain port 504 to the second water receiving member 800 .

[0325] In some embodiments, the drain port 504 is defined by the first segment 510 and the second segment 520 .

[0326] 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 to the second water receiving piece 800 better, the second water receiving piece 800 is defined to form a water receiving channel 801 with a top opening. The second water receiving piece 800 is connected to the bottom of the fresh air piece 500, and the water receiving channel 801 is connected to the air outlet duct through the drain port 504, so that the fresh air condensed water can drip from the drain port 504 to the second water receiving piece 800 under the action of gravity.

[0327] The second water receiving member 800 is provided with a first connection hole 802, and the fresh air member 500 is provided with a first clamping portion, which is arranged corresponding to the first connection hole 802, and the first clamping portion cooperates with the first connection hole 802 to connect the second water receiving member 800 with the fresh air member 500. It should be noted that the first connection 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 of the housing 100 and the rear side of the housing 100.

[0328] The second water receiving member 800 is provided with a lead-out portion 810, and a drainage channel 811 is defined inside the lead-out portion 810, and the drainage channel 811 is communicated with the water receiving channel 801, and the drainage channel 811 is communicated with the drainage pipe 830, so that the fresh air condensed water passes through the drainage channel 811 and enters the drainage pipe 830. It should be noted that the lead-out portion 810 is located on a side of the second water receiving member 800 facing the rear side of the housing 100.

[0329] The outlet portion 810 includes a first slope 814 which is arranged to be inclined downward from the outlet portion 810 toward the drain pipe 830 . The fresh air condensate flows into the drain pipe 830 along the first slope 814 in a downward inclined path. It should be noted that the first slope 814 is the bottom surface of the drain channel 811 .

[0330] 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 inclined downward from the front side of the casing 100 toward the rear side of the casing 100 along the thickness direction of the casing 100 .

[0331] 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, in order to facilitate the connection between the drainage channel 811 of the outlet portion 810 and the drain pipe 830, the base 130 is provided with a connecting portion, and the outlet portion 810 is correspondingly arranged with the connecting portion, so that the outlet portion 810 connects the fresh air condensed water with the drain pipe 830 through the connecting portion. It should be noted that since the second water receiving member 800 is arranged close to the front side of the housing 100, the connecting portion is also arranged close to the front side of the housing 100.

[0332] 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 substantially upward. The heat exchange condensate water flows into the drain pipe 830 from the second water inlet 831, and the fresh air condensate water flows into the drain pipe 830 from the first water inlet 832.

[0333] The connecting part is located below the guide member 133, and the height of the first water inlet 832 is lower than the second water inlet 831. Since the connecting part is also arranged near the front side of the housing 100, and the second guide part 1332 is arranged near the rear side of the housing 100, the heat exchange condensed water passes through the second guide part 1332 and enters the drain pipe 830 from the second water inlet 831, and then easily enters the connecting part from the first water inlet 832 under the action of inertia. After entering the connecting part, the heat exchange condensed water may enter the interior of the housing 100 along the connecting part, thereby affecting the operation of other components.

[0334] In this embodiment, the connecting portion includes a third slope 1091, so that the third slope 1091 is inclined downward from one end of the connecting portion close to the second water receiving piece 800 toward the drain pipe 830, and the second slope of the second guide portion 1332 is inclined downward from the rear side of the casing 100 toward the drain pipe 830. Therefore, the inclination direction of the third slope 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 slope 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.

[0335] In some embodiments, the connecting portion is a connecting channel 109 provided on the base 130, 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 piece 800 is provided in the connecting channel 109 so that the drain channel 811 is connected to the drain pipe 830.

[0336] 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°.

[0337] In order to further prevent the heat exchange condensed water in the second water receiving portion 132 from passing through the second guide portion 1332 and entering the connecting channel 109 from the first water inlet 832, the drain pipe 830 is provided with a blocking portion 108. The blocking portion 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 portion 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.

[0338] When the heat exchange condensed water in the second water receiving part 132 passes through the second guide part 1332 and enters the drain pipe 830 from the second water inlet 831, it is easy to impact the blocking part 108 due to 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.

[0339] In order to ensure that the fresh air condensate 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.

[0340] It should be noted that the drainage channel 811 is usually designed as a channel with an opening at the top to facilitate cleaning of the drainage channel 811 .

[0341] 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 evaporation of condensed water from fresh air.

[0342] 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.

[0343] The outlet portion 810 is provided with a rib 813, which is arranged in the drainage channel 811 and close to the second water receiving member 800. The rib 813 includes a plurality of ribs, and the plurality of ribs 813 are staggered with each other. On the one hand, the rib 813 can slow down the flow rate of fresh air condensation water in the drainage channel 811, and on the other hand, it can increase the connection strength between the outlet portion 810 and the connecting member 820.

[0344] In order to facilitate the drain pipe 830 to drain the fresh air condensate and / or heat exchange condensate, the drain pipe 830 is usually arranged at an angle, that is, the water inlet of the drain pipe 830 is higher than the water outlet of the drain pipe 830. In practical applications, the rear side of the housing 100 is usually arranged toward the wall, and the drain pipe 830 is arranged outdoors through the wall. Therefore, it can be seen that the drain pipe 830 is arranged downwardly at an angle from the front side of the housing 100 to the rear side of the housing 100.

[0345] It should be noted that the drain pipe 830 provided on the base 130 may not be long enough. In practical applications, 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 described in detail.

[0346] 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 air 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 port 504 to the water receiving channel 801 under the action of gravity, and the fresh air condensate dripping to the water receiving channel 801 will pass through the drain channel 811 and enter the drain pipe 830 from the first water inlet 832, and the fresh air condensate will finally be discharged to the outside through the drain pipe 830.

[0347] The heat exchange fan 300 is operated to introduce 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-conditioned air, the air-conditioned air is output to the room from the first air outlet 102; the heat exchange condensed water generated by the air-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, and 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. The kinetic energy of the heat exchange condensed water is weakened after impacting the blocking part 108, 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.

[0348] The wall-mounted air conditioner indoor unit in this embodiment arranges the 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 arranged 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, so as 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 arranged, and a second water inlet 831 is arranged at the connection between the guide member 133 and the drain pipe 830, so as 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 arranged, 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, the fourth air outlet 501 is extended along the length direction of the casing 100 and is set corresponding to the second air outlet 103 to increase the air outlet range of the outdoor fresh air; by setting a second water receiving member 800 and setting a drain outlet 504 on the fresh air member 500, the second water receiving member 800 receives the fresh air condensate generated when the outdoor fresh air is output to the room, so as to prevent the fresh air condensate from damaging other components of the air conditioner indoor unit; by setting a lead-out portion 810, the lead-out portion 810 is used to guide the fresh air condensate to the drain pipe 830; by setting a connecting portion on the casing 100, the lead-out portion 810 can discharge the fresh air condensate into the drain pipe 830 through the connecting portion; by setting a first water inlet 832 on the drain pipe 830, the first water inlet 832 is connected with the connecting portion and the lead-out portion 810, so that the fresh air condensate can be discharged from the first water inlet 832 to the drain pipe 830.

[0349] The heat exchange condensed water and fresh air condensed water in the wall-mounted air-conditioning indoor unit in this embodiment are discharged to the outside through the same drain pipe 830. The overall structure is simple, the assembly is convenient and the cost is low. In addition, the working reliability of the air-conditioning indoor unit is high, and the heat exchange condensed water and fresh air condensed water are discharged in time with good drainage effect.
