Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, specifically, it relates to a vertical air conditioner and its air duct. Background Technology

[0002] Existing vertical air conditioner ductwork typically includes a front volute, a rear volute, and upper and lower mounting brackets located at both ends of the front and rear volutes and connecting them. The upper and lower mounting brackets are generally assembled with the air conditioner and are used to install air guide vanes and their driving mechanisms. Since the air guide vane driving mechanism is generally located above the upper mounting bracket, and the structure of the upper mounting bracket usually differs from that of the lower mounting bracket (the upper bracket has the air guide vane driving mechanism, while the lower mounting bracket does not), the ductwork has poor versatility. This is especially true when the air conditioner includes two symmetrical air conditioning units; the ductwork cannot be interchanged, requiring two sets of duct molds and two sets of ductwork, wasting resources. Furthermore, the installation direction of the ductwork needs to be identified before installation, reducing installation efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an air duct for a vertical air conditioner, which solves the technical problem that when an air conditioner includes two symmetrical air conditioning bodies, the existing air ducts cannot be used interchangeably, requiring two sets of air duct molds and two sets of air ducts to be manufactured, which wastes resources.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0005] A vertical air conditioner duct includes a front volute, a rear volute, and an upper mounting base and a lower mounting base for assembly with a cross-flow fan. The upper mounting base and the lower mounting base are respectively connected to the front volute and the rear volute, characterized in that the upper mounting base and the lower mounting base are symmetrically arranged.

[0006] As described above, in the air duct of the vertical air conditioner, both the upper mounting base and the lower mounting base have air guide plate mounting positions for mounting air guide plates.

[0007] As described above, in the air duct of the vertical air conditioner, both the upper surface of the upper mounting base and the lower surface of the lower mounting base have drive mechanism mounting positions for mounting the air guide plate drive mechanism.

[0008] As described above, in the air duct of the vertical air conditioner, both the upper surface of the upper mounting base and the lower surface of the lower mounting base have limiting portions for restricting the rotation range of the air guide plate.

[0009] As described above, in the air duct of the vertical air conditioner, the limiting part is a cylinder with a notch located around the air guide plate mounting position.

[0010] As described above, the air duct of the vertical air conditioner has through holes for draining condensate from both the upper and lower mounting bases.

[0011] As described above, in the duct of the vertical air conditioner, the upper mounting base is installed on the upper base, and the lower mounting base is installed on the lower base. Both the upper mounting base and the lower mounting base have base mounting positions for assembly with the upper base and the lower base.

[0012] A vertical air conditioner includes a base and at least two air conditioner bodies located on the base. Each air conditioner body has an air inlet and an air outlet. Each air conditioner body is equipped with a cross-flow fan and a cross-flow duct as described in any one of claims 1-7. A cross-flow duct is formed between adjacent first and second air conditioner bodies. A rear air intake of the cross-flow duct is formed between the rear ends of the first and second air conditioner bodies. An upper air intake of the cross-flow duct is formed between the upper ends of the first and second air conditioner bodies. An air outlet of the cross-flow duct is formed between the front ends of the first and second air conditioner bodies. The air outlets of the first and second air conditioner bodies are located within the cross-flow duct. When the first and second air conditioner bodies are configured such that the corresponding cross-flow fans generate negative pressure in the cross-flow duct, air from outside the first and second air conditioner bodies enters the cross-flow duct through the rear air intake and the upper air intake. The air outlet discharges air from the cross-flow duct.

[0013] As described above, in the vertical air conditioner, an upper through-ventilation duct is formed between the first air conditioner body and the second air conditioner body, above the air outlet, and the upper through-ventilation duct is connected to the upper air intake and the through-ventilation duct.

[0014] As described above, in the vertical air conditioner, a lower through-ventilation duct is formed between the first air conditioner body and the second air conditioner body, below the air outlet. The lower through-ventilation duct is connected to the through-ventilation duct. A lower air intake is formed between the rear ends of the first air conditioner body and the second air conditioner body, which is connected to the lower through-ventilation duct. The lower air intake is located below the rear air intake.

[0015] Compared with existing technologies, the advantages and positive effects of this invention are as follows: The upper and lower mounting bases of the air duct are symmetrically arranged, thus the installation direction of the air duct in both the upper and lower directions can be interchanged arbitrarily, enabling assembly of the air duct with the air conditioner body and air guide plate, greatly improving the versatility of the air duct. Especially for air conditioners comprising two symmetrically arranged air conditioner bodies, the air duct can be used both left and right, requiring only one set of air duct molds, greatly saving resources, facilitating installation, simplifying the installation process, and improving installation efficiency.

[0016] This invention relates to a vertical air conditioner comprising at least two air conditioner bodies. A through-ventilation duct is formed between adjacent first and second air conditioner bodies. The rear ends of the first and second air conditioner bodies form the rear air inlet of the through-ventilation duct, and the upper ends of the first and second air conditioner bodies form the upper air inlet of the through-ventilation duct. The air inlets of this invention include a rear air inlet and an upper air inlet, expanding the airflow range, significantly increasing the airflow volume, improving the airflow effect, and resulting in a gentler and more comfortable airflow from the outlet. The air outlet of this invention is located within a through-ventilation duct. The air outlet can create a large negative pressure within the through-ventilation duct, introducing a large amount of non-heat exchange air from the outside to mix with the heat exchange air to form a mixed air. The mixed air can diffuse quickly and evenly from the air supply outlet, resulting in a more uniform and comfortable air supply temperature. The through-ventilation duct between the air outlet and the air intake can streamline the intake non-heat exchange air, which not only helps to increase the air intake volume but also improves the mixing uniformity of the non-heat exchange air and the heat exchange air. At the same time, this invention can achieve sufficient mixing within the through-ventilation duct between the air outlet and the air supply outlet, further ensuring the uniformity of the mixed air and improving the comfort and uniformity of the air supply.

[0017] Other features and advantages of the present invention will become clearer after reading the detailed embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0037] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] First, a brief explanation of the technical terms involved in the specific implementation methods:

[0039] When referring to the front or back, top or bottom, left or right of each structural component, the terms "front" or "back," "top or bottom," or "left or right" are defined relative to the user's position during normal use. Furthermore, it should be noted that the use of "front" or "back," "top or bottom," and "left or right" is merely for ease of description and simplification, and does not indicate or imply that the device or structural component must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation on the invention. The heat exchange air referred to below is air from inside the air conditioner unit after heat exchange with the heat exchanger; non-heat exchange air refers to air from the ambient space where the air conditioner unit is located, which is relative to the heat exchange air and does not come directly from the heat exchanger; mixed air refers to air formed by the mixture of heat exchange air and non-heat exchange air.

[0040] An air conditioner consists of an indoor unit and an outdoor unit. The indoor and outdoor units are connected by a connecting pipe to achieve refrigerant circulation. The indoor and outdoor units are connected by a connecting line to achieve power supply and communication. The drain pipe of the indoor unit's water tray leads to the outside.

[0041] like Figure 1-6 As shown in Figures 11, 12, and 13, this embodiment takes a vertical air conditioner indoor unit as an example for explanation. The vertical air conditioner indoor unit of this embodiment includes a base 1 and a first air conditioner body 100 and a second air conditioner body 200 located on the base 1.

[0042] The first air conditioner body 100 includes a cylindrical first housing 101. A first air inlet 102 and a first air outlet 103 are provided on the first housing 101. A first air duct 105 and a first cross-flow fan 104 are disposed inside the first housing 101. A first heat exchanger 106 is disposed between the first cross-flow fan 104 and the first air inlet 102. The first cross-flow fan 104 is used to direct airflow from the first air inlet 102 to the first air outlet 103. That is, when the first air conditioner body 100 is working, the first cross-flow fan 104 rotates, drawing air from outside the first air conditioner body 100 into the first air conditioner body 100 through the first air inlet 102. After heat exchange with the first heat exchanger 106, the heat-exchanged air is blown out from the first air outlet 103. A first swashplate (not shown in the figure) and / or a first air guide plate 108 are provided at the first air outlet 103 to adjust the airflow direction, thereby meeting the user's airflow direction requirements. Both the first air outlet 103 and the first air inlet 102 are elongated.

[0043] like Figure 10 , 11As shown in Figures 12 and 13, the first air duct 105 of this embodiment includes a front volute 1051, a rear volute 1052, and an upper mounting base 1053 and a lower mounting base 1054 for assembly with the first cross-flow fan 104. The upper mounting base 1053 and the lower mounting base 1054 are respectively connected to the front volute 1051 and the rear volute 1052. The front volute 1051 and the rear volute 1052 are arranged in the vertical direction. The upper mounting base 1053 is connected to the upper end of the front volute 1051 and the rear volute 1052, and the lower mounting base 1054 is connected to the lower end of the front volute 1051 and the rear volute 1052. The upper mounting base 1053 and the lower mounting base 1054 are symmetrically arranged. The symmetrical arrangement of the upper mounting base 1053 and the lower mounting base 1054 means that the shapes and structures of the upper mounting base 1053 and the lower mounting base 1054 are symmetrical. Among them, the cross-sections of the upper mounting base 1053 and the lower mounting base 1054 at the middle of the front volute 1051 and the rear volute 1052 are symmetrical.

[0044] Both the upper mounting base 1053 and the lower mounting base 1054 have air guide plate mounting positions 400 for mounting the air guide plate. Therefore, the rotation direction of the upper mounting base 1053 and the lower mounting base 1054 will not affect the installation of the air guide plate.

[0045] The upper surface of the upper mounting base 1053 and the lower surface of the lower mounting base 1054 both have a drive mechanism mounting position 401 for mounting the air guide plate drive mechanism and a limiting part 402 for limiting the rotation range of the air guide plate. Therefore, the flipping direction of the upper mounting base 1053 and the lower mounting base 1054 will not affect the installation of the air guide plate drive mechanism.

[0046] Preferably, the limiting part 402 is a cylinder with a notch located on the periphery of the air guide plate mounting position 400. The air guide plate driving mechanism includes a rotating shaft (not shown in the figure) and a limiting arm (not shown in the figure) that is linked to the rotating shaft. The limiting arm rotates within the notch. When the limiting arm contacts the two ends of the notch, it achieves limiting. The notch can limit and guide the rotation of the limiting arm.

[0047] Both the upper mounting base 1053 and the lower mounting base 1054 have through holes 403 for draining condensate. The mounting base located below the air guide plate can collect condensate from the air guide plate and drain it into a drip tray. Therefore, the rotation direction of the upper mounting base 1053 and the lower mounting base 1054 will not affect the function of the mounting base below the air guide plate in collecting condensate and draining it into the drip tray.

[0048] The upper mounting base 1053 is mounted on the first upper base 111, and the lower mounting base 1054 is mounted on the first lower base 110. Both the upper mounting base 1053 and the lower mounting base 1054 have base mounting positions 404 for assembly with the first upper base 111 and the first lower base 110. Therefore, the rotation direction of the upper mounting base 1053 and the lower mounting base 1054 will not affect the assembly of the base mounting positions 404 with the first upper base 111 and the first lower base 110.

[0049] The second air conditioner body 200 includes a cylindrical second housing 201. A second air inlet 202 and a second air outlet 203 are provided on the second housing 201. A second air duct 205 and a second cross-flow fan 204 are disposed inside the second housing 201. A second heat exchanger 206 is disposed between the second cross-flow fan 204 and the second air inlet 202. The second cross-flow fan 204 directs airflow from the second air inlet 202 to the second air outlet 203. That is, when the second air conditioner body 200 is operating, the second cross-flow fan 204 rotates, drawing air from outside the second air conditioner body 200 through the second air inlet 202 into the second air conditioner body 200. After heat exchange with the second heat exchanger 206, the heat-exchanged air is blown out from the second air outlet 203. A second swashplate (not shown in the figure) and / or a second air guide plate 208 are provided at the second air outlet 203 to adjust the airflow direction and meet the user's airflow direction requirements. Both the second air outlet 203 and the second air inlet 202 are elongated.

[0050] Flipping the first air duct 105 vertically forms the second air duct 205. Therefore, the versatility of the air duct in this embodiment is greatly improved, allowing the same air duct to be used interchangeably with both the first and second air conditioning units. This embodiment requires only one set of air duct molds, significantly saving resources. Furthermore, there is no need to consider the difference between the upper and lower mounting brackets during installation, which facilitates installation, simplifies the installation process, and improves installation efficiency.

[0051] In this embodiment, the cross-sections of the first housing 101 and the second housing 201 are both elliptical. Of course, the cross-sections of the first housing 101 and the second housing 201 of the present invention can also be approximately elliptical, triangular, or polygonal, etc., all of which are within the protection scope of the present invention.

[0052] A through-ventilation duct 300 is formed between the first air conditioning body 100 and the second air conditioning body 200. The rear end L12 of the first air conditioning body 100 and the rear end L22 of the second air conditioning body 200 form the rear air intake 301 of the through-ventilation duct 300. The upper end of the first air conditioning body 100 and the second air conditioning body 200 forms the upper air intake 302 of the through-ventilation duct 300. The front end L11 of the first air conditioning body 100 and the front end L21 of the second air conditioning body 200 form the air outlet 303 of the through-ventilation duct 300. The front end of the through-ventilation duct 300 is connected to the air supply outlet 303, the rear end of the through-ventilation duct 300 is connected to the rear air intake outlet 301, and the upper end of the through-ventilation duct 300 is connected to the upper air intake outlet 302. Therefore, the through-ventilation duct 300 can simultaneously draw air from both the rear air intake outlet 301 and the upper air intake outlet 302. In this embodiment, the air intake range is expanded, and the air intake volume is greatly increased. This can increase the air volume of non-heat exchange air in the mixed air, making the temperature of the mixed air more mild and comfortable. At the same time, due to the increased air intake volume, the airflow in the room can also be improved, enabling the room temperature to be quickly and evenly regulated. Both the rear air intake outlet 301 and the air supply outlet 303 are elongated.

[0053] In this embodiment, the through-ventilation duct 300 is formed by the gap between the first housing 101 and the second housing 201. The duct wall of the through-ventilation duct 300 is the opposite side of the first housing 101 and the second housing 201, that is, the inner side of the first housing 101 and the second housing 201. Of course, the duct wall of the through-ventilation duct 300 can also be set separately, independent of the first housing 101 and the second housing 201, and can be fixed to the housing or not fixed to the housing. In this case, the through-ventilation duct 300 is the space between the duct walls. Of course, the duct wall can also include part of the housing and a separately set part of the duct wall, with the part of the duct wall fixed to the part of the housing to form a complete duct wall. In this case, the through-ventilation duct 300 is the space between the part of the duct wall and the part of the housing.

[0054] The air outlet 103 of the first air conditioning unit 100 and the air outlet 203 of the second air conditioning unit 200 are both located within the cross-ventilation duct 300. The first air conditioning unit 100 and the second air conditioning unit 200 are configured such that when the first cross-flow fan 104 and the second cross-flow fan 204 rotate, the negative pressure generated within the cross-ventilation duct 300 causes air from outside the first air conditioning unit 100 and the second air conditioning unit 200 to enter the cross-ventilation duct 300 through the rear air intake 301 and the upper air intake 302, forming non-heat exchange air. Simultaneously, heat exchange air from the first air conditioning unit 100 and the second air conditioning unit 200 is blown into the cross-ventilation duct 300 from the first air outlet 103 and the second air outlet 203, respectively. Within the cross-ventilation duct 300, the non-heat exchange air and the heat exchange air mix to form a comfortable temperature mixed air. The air outlet 303 then delivers the air from the cross-ventilation duct; that is, the air outlet 303 delivers the comfortable temperature mixed air.

[0055] The first air outlet 103 and the second air outlet 203 are located within the through-ventilation duct 300. The air outlets 103 and 203 can create a large negative pressure zone B within the through-ventilation duct 300, introducing a large amount of non-heat exchange air from the outside into the through-ventilation duct 300. The non-heat exchange air and the heat exchange air mix within the through-ventilation duct 300 to form mixed air. The mixed air can diffuse quickly and evenly from the air outlet 303, resulting in a relatively uniform and comfortable air supply temperature. The through-ventilation duct between the first air outlet 103, the second air outlet 203, and the rear air intake 301 can organize the non-heat exchange air drawn in by the rear air intake 301, which not only helps to increase the air intake volume but also improves the mixing uniformity of the non-heat exchange air and the heat exchange air. At the same time, the non-heat exchange air and the heat exchange air are fully mixed within the through-ventilation duct 300 between the first air outlet 103, the second air outlet 203, and the air outlet 303, further ensuring the uniformity of the mixed air and improving the comfort and uniformity of the air supply.

[0056] To further improve the air intake effect, the structure of the through-ventilation duct 300 is optimized. The inner diameter of the through-ventilation duct 300 gradually narrows and then widens from the rear air intake vent 301 to the air supply vent 303. The air outlet is located on the widening section, and the air outlets do not interfere with each other, thus increasing the air outlet angle and air supply distance. At the same time, a negative pressure zone B is formed between the first air outlet 103, the second air outlet 203, and the air supply vent 303. Under the action of negative pressure, the air outside the first air conditioning unit 100 and the second air conditioning unit 200 enters the through-ventilation duct 300 through the rear air intake vent 301, passing through the narrowing section first and then the widening section. This increases the wind speed of the non-heat exchange air in the through-ventilation duct 300, thereby improving the air intake effect.

[0057] The arrangement of the air outlet positions in this embodiment makes it possible for the air outlets at the first and second outlets to have the same airflow direction. The airflow from the first and second outlets does not cross, and they will not affect or interfere with each other. This helps to reduce the wind resistance and noise caused by the mutual interference of the airflow from the two outlets, which is beneficial for air delivery. The air delivery angle and air delivery distance are both improved.

[0058] The air conditioner body has an elliptical cross-sectional shape, with the air inlet and air outlet located on opposite sides of the ellipse's major axis. The first air inlet 102 and the first air outlet 103 are located on opposite sides of the elliptical cross-section of the first air conditioner body 100, while the second air inlet 202 and the second air outlet 203 are located on opposite sides of the elliptical cross-section of the second air conditioner body 200. This shortens the airflow path within the air conditioner body, reducing wind resistance and noise.

[0059] To increase the air delivery angle and distance, such as Figure 6As shown, on the same cross-section of the first air conditioner body 100 and the second air conditioner body 200, the first line connecting the front end L11 and rear end L12 of the first air conditioner body 100 intersects with the second line connecting the front end L21 and rear end L22 of the second air conditioner body 200. The distance between the front end L11 of the first air conditioner body 100 and the front end L21 of the second air conditioner body 200 is greater than the distance between the rear end L12 of the first air conditioner body 100 and the rear end L22 of the second air conditioner body 200. Therefore, the first air conditioner body 100 and the second air conditioner body 200 gradually expand from the air intake direction of the ventilation duct 300 to the air supply direction, increasing the air supply angle and air supply distance. Preferably, the angle between the first line and the second line is greater than 0 degrees and less than or equal to 45 degrees. Within this angle, a balance between the air intake effect and the air supply angle and air supply distance can be achieved.

[0060] Of course, the first line connecting the front end L11 and the rear end L12 of the first air conditioner body 100 is parallel to the second line connecting the front end L21 and the rear end L22 of the second air conditioner body 200. The distance between the front end L11 of the first air conditioner body 100 and the front end L21 of the second air conditioner body 200 is equal to the distance between the rear end L12 of the first air conditioner body 100 and the rear end L22 of the second air conditioner body 200, which is also within the protection scope of this invention.

[0061] In this embodiment, the first air outlet 103 of the first air conditioner body 100 and the second air outlet 203 of the second air conditioner body 200 are both located within the ventilation duct 300 and close to the air supply outlet 303. The air blown out of the first air outlet 103 is directed towards the air supply outlet 303, and the air blown out of the second air outlet 203 is directed towards the air supply outlet 303. The air blown out of the first air outlet 103 and the second air outlet 203 will not interfere with each other, and the air supply angle and air supply distance are greatly improved, which is conducive to the flow of indoor air.

[0062] In this embodiment, the first air inlet 102 is located on the outer side of the first air conditioner body 100, and the second air inlet 202 is located on the outer side of the second air conditioner body 200. The positions of the air inlets and the rear air outlets are at a certain distance, which not only reduces the interference of airflow at the air inlets and the rear air outlets, but also shortens the airflow path within the air conditioner body, thus reducing wind resistance and noise. Furthermore, the air inlet is located on the outer side of the air conditioner body, while the air outlet is located within the ventilation duct, i.e., on the inner side of the air conditioner body. The position of the air outlet allows the air to travel a longer distance, preventing the air from being directly drawn into the air inlet, which is beneficial for indoor air circulation and enables rapid and even temperature regulation. Of course, when there are more than two air conditioner bodies, in order to form a ventilation duct between adjacent air conditioner bodies, the air inlet 202 needs to be located on the rear side of the air conditioner body.

[0063] The first air conditioning unit 100 and the second air conditioning unit 200 are symmetrically arranged, and the first air conditioning unit 100 and the second air conditioning unit have a symmetrical plane, which is the plane formed by the center line of the rear air intake vent 301 in the length direction and the center line of the air supply vent 303 in the length direction. The symmetrical arrangement of the first air conditioning unit 100 and the second air conditioning unit 200 means that the shapes of the first housing 101 and the second housing 201 are symmetrically symmetrical, the first air inlet 102 on the first housing 101 and the second air inlet 202 on the second housing 201 are symmetrically symmetrical, the first air outlet 103 on the first housing 101 and the second air outlet 203 on the second housing 201 are symmetrically symmetrical, and the first air duct 105, the first cross-flow fan 104, and the first heat exchanger 106 in the first housing 101 and the second air duct 205, the second cross-flow fan 204, and the second heat exchanger 206 in the second housing 201 are symmetrically symmetrical, so as to further improve the uniformity of air intake, air mixing and air supply.

[0064] To improve the stability of the first air conditioner body 100 and the second air conditioner body 200, the upper parts of the first air conditioner body 100 and the upper parts of the second air conditioner body 200 can be connected by a top connector 2. To reduce the impact of the top connector 2 on the air intake effect, the top connector 2 in this embodiment is a long and thin strip. To improve the aesthetics of the indoor unit, the top connector 2 is a transparent part, and icons, logos, etc. can be set on the transparent part.

[0065] To further increase the induced draft, such as Figure 1 , 7 As shown, in this embodiment, an upper through-ventilation duct 304 is formed between the first air conditioning body 100 and the second air conditioning body 200, above the air outlet. There is a certain height difference H1 between the upper end of the air outlet and the upper end of the air conditioning body. The upper through-ventilation duct 304 is the space marked H1 between the first air conditioning body 100 and the second air conditioning body 200. The upper through-ventilation duct 304 is connected to the upper air intake vent 302 and the through-ventilation duct 300. At this time, the upper air intake vent 302 is formed at the position corresponding to the upper through-ventilation duct 304 between the upper ends of the two air conditioning bodies and between the rear ends of the two air conditioning bodies. The upper air intake vent 302 between the rear ends of the air conditioning bodies is located above the rear air intake vent 301, further increasing the vent area. Under the action of negative pressure, the air at the upper air intake vent 302 first enters the upper through-ventilation duct 304 and is combed within the upper through-ventilation duct 304. This not only helps to increase the air intake volume of the upper air intake vent 302 but also improves the mixing uniformity of non-heat exchange air and heat exchange air.

[0066] To further increase the induced draft, such as Figure 1 , 8As shown in Figure 9, this embodiment can further include a lower through-ventilation duct 305, which is the space marked H2 between the first air conditioning unit 100 and the second air conditioning unit 200. In this embodiment, a lower through-ventilation duct 305 is formed between the two air conditioning units, below the air outlet. The lower through-ventilation duct 305 is connected to the through-ventilation duct 300. A lower air intake vent 306, connected to the lower through-ventilation duct 305, is formed between the rear ends of the first air conditioning unit 100 and the second air conditioning unit 200. The lower air intake vent 306 is located below the rear air intake vent 301. Under negative pressure, the air at the lower air intake vent 306 first enters the lower through-ventilation duct 305 and is combed within it. This not only helps to increase the air intake volume of the lower air intake vent 306 but also improves the mixing uniformity of non-heat exchange air and heat exchange air.

[0067] like Figure 1 , 2 As shown in Figures 5, 9, and 10, the inlet and outlet pipes of the first heat exchanger 106 of the first air conditioner body 100 and the second heat exchanger 206 of the second air conditioner body 200 are connected to the connection pipe of the outdoor unit. The drain pipe of the first water receiving pan 109 at the bottom of the first heat exchanger 106 needs to be connected to the outdoor drainage, and the drain pipe of the second water receiving pan 209 at the bottom of the second heat exchanger 206 also needs to be connected to the outdoor drainage. In order to simplify the structure of the indoor unit and increase the stability of the indoor unit, in this embodiment, the inlet and outlet pipes of the first heat exchanger 106 and the second heat exchanger 206 are connected to the outdoor drainage. After the water flows into the manifold, it is connected to the outdoor connection pipe. The water from the first water tray 109 and the second water tray 209 flows into a converging part through the guide part. In order to accommodate components such as the manifold, guide part, converging part and drain pipe, in this embodiment, the first air conditioner body 100 and the second air conditioner body 200 are connected below the air outlet by a connecting device. The connecting device is connected to the base 1. The first air conditioner body 100, the second air conditioner body 200, the base 1 and the connecting device form a receiving cavity for accommodating components such as the manifold and drain pipe.

[0068] like Figure 1 As shown, in this embodiment, the lower end of the air outlet and the middle connecting plate 5 have a certain height difference H2, forming a lower through-ventilation duct 305 between the air outlet and the middle connecting plate 5. The lower through-ventilation duct 305 is the space marked H2 between the first air conditioning body 100 and the second air conditioning body 200.

[0069] like Figure 9As shown, to further increase the lower air intake 306, the front connecting plate 3 is connected to the middle of the inner side of the first air conditioning body 100 and the second air conditioning body 200. The front connecting plate 3, the middle connecting plate 5, and the rear connecting plate 4 are all located behind the plane F where the rear end of the air outlet is located. There is a certain gap between the front connecting plate 3 and the plane F where the rear end of the air outlet is located. A lower air intake area 307 is formed in front of the front connecting plate 3. Under the action of negative pressure, the air in the lower air intake area 307 in front of the front connecting plate 3 first enters the lower through-ventilation duct 305 and is combed in the lower through-ventilation duct 305, further increasing the air intake volume of the lower air intake 306 and improving the mixing uniformity of non-heat exchange air and heat exchange air.

[0073] A water collection tray is installed on the front column, rear column, and short column. Above the water collection tray, a lower base, an air duct, and an upper base are arranged in sequence. The upper and lower bases are used to install and support the air duct. The upper and lower bases are fixedly installed on the front and rear columns. The air duct is used to install the cross-flow fan. The cross-flow fan is located inside the air duct. The heat exchanger is located between the cross-flow fan and the air inlet. The heat exchanger is located above the water collection tray and fixedly installed on the front and rear columns. The motor that drives the cross-flow fan is installed on the upper base. A top cover is provided on the top of the upper base. Specifically, in the first air conditioner body 100, a first water receiving tray 109 is installed on the front column 61, the middle column 62, and the rear column 63. Above the first water receiving tray 109, a first lower base 110, a first air duct 105, and a first upper base 111 are sequentially arranged. The first upper base 111 and the first lower base 110 are used to install and support the first air duct 105. The first upper base 111 and the first lower base 110 are fixedly installed on the front column 61 and the middle column 62. The first air duct 105... 05 is used to install the first cross-flow fan 104. The first cross-flow fan 104 is located inside the first air duct 105. The first heat exchanger 106 is located between the first cross-flow fan 104 and the first air inlet 102. The first heat exchanger 106 is located above the first water receiving tray 109 and is fixedly installed on the front column 61 and the middle column 62. The first motor 113 that drives the first cross-flow fan 104 is installed on the first upper base 111. The top of the first upper base 111 is provided with a first top cover 112. In the second air conditioning body 200, a second water receiving tray 209 is installed on the front column 61, the middle column 62, and the rear column 63. Above the second water receiving tray 209, a second lower base 210, a second air duct 205, and a second upper base 211 are arranged in sequence. The second upper base 211 and the second lower base 210 are used to install and support the second air duct 205.

[0074] In this embodiment, the first water receiving tray 109 and the second water receiving tray 209 are connected to a manifold 7 via a guide portion. The manifold 7 is used to collect the condensate from the water receiving trays 109 and 209, and the guide portion directs the condensate from the water receiving trays to the manifold. The water receiving tray, the guide portion, and the manifold are integrally formed. Therefore, the first air conditioner body and the second air conditioner body are connected through the water receiving tray, the guide portion, and the manifold, which greatly increases the stability of the connection between the first air conditioner body and the second air conditioner body.

[0075] The spaces below the first water tray 109 inside the first air conditioner body 100 and below the second water tray 209 inside the second air conditioner body 200 can be used to place other air conditioner accessories, such as humidification modules and electrical modules.

[0076] The assembly relationship of the indoor unit in this embodiment makes the structure of the indoor unit more compact and neat, and the installation convenient and quick.

[0077] When the air conditioner is running, the cross-flow fan rotates, drawing outside air into the air conditioner through the air inlet. There, air exchanges heat with the heat exchanger, generating heat-exchanged air that is blown out from the air outlet. This creates negative pressure within the cross-flow duct, forcing outside air to enter the cross-flow duct through the rear air intake, then through the upper air intake and upper cross-flow duct, and finally through the lower air intake, lower air intake area, and lower cross-flow duct, forming non-heat-exchanged air. Figure 9 As shown, heat exchange air and non-heat exchange air mix in the ventilation duct to form a comfortable temperature mixed air, which is then delivered from the air outlet.

[0078] Of course, this embodiment is only illustrated by taking an indoor air conditioner unit that includes two air conditioner bodies as an example. The number of air conditioner bodies in the indoor air conditioner unit of the present invention can be determined according to actual needs. When there are more than two air conditioner bodies, multiple air conditioner bodies are arranged side by side on the base 1.
