Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit with a sliding air guide plate. Background Technology

[0002] Traditional wall-mounted air conditioners typically use a cross-flow air supply system, which suffers from problems such as a small air outlet angle, small air supply range, low air outlet velocity, short air supply distance, cold air blowing easily into people, and hot air not reaching the ground. Therefore, some wall-mounted air conditioners on the market now use axial flow fans. These units have air outlets on the front panel and side panels, with the axial flow fan positioned upstream of multiple air outlets. Simultaneously pivoting air guide grilles are installed at the air outlets to optimize the airflow performance of the wall-mounted air conditioner.

[0003] However, existing axial-flow wall-mounted air conditioners place the axial fan at the air outlet and the heat exchanger on the air inlet side of the axial fan. This cannot effectively guarantee the air velocity distribution at the heat exchanger inlet, easily leading to uneven airflow distribution and affecting heat exchange efficiency. Furthermore, placing the axial fan directly at the air outlet also results in significant noise. Additionally, the air guide grille at the air outlet of existing air conditioners only partially extends out of the outlet and pivots synchronously to change the airflow direction when the unit is turned on. This results in a limited airflow effect, failing to achieve wide-range diffusion and long-distance convergence, thus failing to meet diverse user needs for airflow and also compromising the aesthetics of the air outlet. Utility Model Content

[0004] In view of the above problems, this utility model proposes an air conditioning indoor unit with multi-form axial flow air supply that overcomes or at least partially solves the above problems.

[0005] One objective of this invention is to provide an air conditioner indoor unit that enhances the overall design aesthetics, thereby improving the user experience.

[0006] A further objective of this invention is to improve the heat exchange efficiency of the indoor unit of an air conditioner.

[0007] Another further objective of this invention is to improve the heat exchange uniformity of the indoor unit of the air conditioner.

[0008] Specifically, this utility model provides an indoor unit for an air conditioner, comprising:

[0009] The casing has a forward-opening air outlet in the middle of its front side;

[0010] At least one axial flow fan, disposed within the housing, is used to direct airflow within the housing through an outlet; and

[0011] Multiple air guide vanes are vertically slidably installed at the air outlet to open or close at least a portion of the air outlet, thereby adjusting the direction of the airflow blowing out from the air outlet.

[0012] Optionally, the indoor unit of the air conditioner includes two vertically spaced air guide vanes, and the two adjacent sides of the two air guide vanes define an opening area that forms an air outlet, so that the height and vertical dimensions of the opening area can be adjusted by adjusting the position of the two air guide vanes.

[0013] Optionally, the two air guides have a diffuser position where the air outlet is fully opened to guide the airflow inside the housing to diffuse forward from the air outlet, a converging position where only the middle area of ​​the air outlet is opened to guide the airflow inside the housing to converge forward from the open area, an upward blowing position where only the upper area of ​​the air outlet is opened to guide the airflow inside the housing to tilt forward and upward from the open area, and a downward blowing position where only the lower area of ​​the air outlet is opened to guide the airflow inside the housing to tilt forward and downward from the open area. Each air guide can be controlled to move independently so that the two air guides can switch between the diffuser position, the converging position, the upward blowing position, and the downward blowing position.

[0014] Optionally, the housing includes a rear cover, an air outlet frame, and a front panel arranged sequentially in the front-rear direction. The rear cover has an air inlet, the front panel is a vertically arranged flat plate, and the air outlet is located in the vertical center of the front panel so that the airflow at the air outlet has a tendency to blow forward.

[0015] Optionally, each air guide plate includes a vertically arranged plate body, and the plates of both air guide plates are fitted to the side of the front panel adjacent to the air outlet frame and are respectively located on the upper and lower sides of the air outlet.

[0016] Optionally, each air guide plate also includes a guide plate that extends backward at an angle from one side edge of the plate body near the center of the air outlet toward the center of the air outlet, and the guide plates of the two air guide plates are used to guide the airflow in the housing toward the air outlet.

[0017] Optionally, two horizontally extending baffles are provided at the upper and lower ends of the side of the air outlet frame adjacent to the front panel, so as to form a storage space for accommodating the air guide plate defined in front of the front panel.

[0018] Optionally, the central axis of each axial fan extends horizontally and is arranged parallel to the front-rear direction of the casing.

[0019] Optionally, the indoor unit of the air conditioner includes multiple axial fans, which are spaced apart along the length of the air outlet so that the airflow inside the casing is blown forward by the multiple axial fans.

[0020] Optionally, the indoor unit of the air conditioner also includes:

[0021] The heat exchanger is housed inside the casing and located between the axial fan and the air outlet, and is used to exchange heat with the airflow blown out by the axial fan.

[0022] This utility model discloses an indoor air conditioning unit, comprising a housing, at least one axial flow fan, and multiple air guide plates. By providing a forward-opening air outlet in the center of the front side of the housing, the axial flow fan is housed within the housing to direct airflow from within the housing through the air outlet, achieving overall forward-facing axial airflow. Furthermore, multiple air guide plates are vertically slidable at the air outlet, used to open or close at least a portion of the air outlet to adjust the direction of the airflow. This allows for flexible adjustment of the air outlet's opening area to freely change the airflow direction, meeting the airflow requirements at different positions and angles, and achieving multi-form axial airflow, avoiding the problem of a single airflow method. Simultaneously, the vertically sliding air guide plates at the front air outlet of this utility model prevent the air guide plates from protruding from the housing and disrupting the overall appearance of the front side of the indoor air conditioning unit, maintaining the aesthetic appeal of the air outlet, enhancing the overall design of the indoor air conditioning unit, and thus improving the user experience.

[0023] Furthermore, the indoor unit of this utility model includes two vertically spaced air guide plates, and the two adjacent sides of the two air guide plates define an opening area for the air outlet. By adjusting the position of the two air guide plates, the height and vertical dimension of the opening area can be adjusted, which improves the accuracy of adjusting the height and vertical dimension of the air outlet area, better adapts to different air supply needs, and thus realizes directional air supply to spaces of different heights or users in different positions, thereby improving the heat exchange efficiency of the indoor unit of the air conditioner.

[0024] Furthermore, in the indoor unit of this invention, the central axis of each axial fan extends horizontally and is set parallel to the front and rear direction of the casing. This enables the airflow inside the casing to flow forward and blow out from the air outlet. Compared with the traditional forward and downward air outlet scheme, this improves the adjustability of the air supply angle and the maximum air supply distance, which helps the heat exchange airflow reach a farther area to cover the room more evenly. This improves the uniformity of the heat exchange airflow distribution in the room and thus improves the heat exchange uniformity of the indoor unit.

[0041] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0042] like Figure 1 As shown, the indoor unit 10 of the air conditioner according to this embodiment generally includes a housing 100. Specifically, a forward-opening air outlet 150 is provided in the middle of the front side of the housing 100. Thus, the air outlet direction of the indoor unit 10 of the air conditioner according to this invention is forward air outlet.

[0043] like Figures 2 to 14 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention may further include at least one axial flow fan 200. Specifically, the axial flow fan 200 is disposed inside the housing 100 and is used to cause the airflow inside the housing 100 to be blown out through the air outlet 150. That is to say, the indoor unit 10 of the air conditioner in this embodiment of the present invention has an axial flow fan 200 disposed upstream of the air outlet 150 to cause the airflow inside the housing 100 to flow forward and be blown out through the air outlet 150, thereby realizing axial flow air supply with the entire unit expelling air forward.

[0044] like Figures 1-2 and Figures 5 to 14 As shown, the indoor unit 10 of this embodiment of the air conditioner may further include multiple air guide plates (not shown in the figure). Specifically, the multiple air guide plates are vertically slidably disposed at the air outlet 150, and are used to open or close at least a portion of the air outlet 150 to adjust the airflow direction from the air outlet 150. In other words, the indoor unit 10 of this embodiment of the air conditioner achieves adjustment of the airflow direction from the air outlet 150 by providing multiple air guide plates at the forward-discharging air outlet 150, and by using the multiple air guide plates to open different areas of the air outlet 150.

[0045] The indoor unit of this utility model of an air conditioner has multiple vertically sliding air guide plates installed at the forward-opening air outlet 150. These multiple air guide plates are used to open or close at least a part of the air outlet 150, which realizes the ability to freely change the airflow direction by flexibly adjusting the opening area of ​​the air outlet 150. This meets the air supply needs of different positions and angles, realizes multi-form axial flow air supply, and avoids the problem of a single air supply form.

[0046] In addition, the air conditioner indoor unit of this utility model has a vertically sliding air guide plate at the front air outlet 150, which avoids the damage to the overall appearance of the front side of the air conditioner indoor unit caused by the air guide plate protruding from the shell, maintains the aesthetics of the air outlet 150, enhances the overall design of the air conditioner indoor unit, and thus improves the user experience.

[0047] In some embodiments, such as Figures 1-2 and Figures 5 to 14 As shown, the number of air guide vanes in the indoor unit 10 of the air conditioner can be two. That is, the indoor unit 10 of the air conditioner includes two air guide vanes arranged vertically at intervals. Specifically, the two adjacent sides of the two air guide vanes define an opening area 151 forming an air outlet 150, so that the height and vertical dimension of the opening area 151 can be adjusted by adjusting the position of the two air guide vanes, so that the airflow inside the casing blows outward from the opening area 151 of the air outlet 150.

[0048] In one specific embodiment, such as Figures 6 to 14 As shown, the two air guide plates include an upper air guide plate 500 and a lower air guide plate 600 arranged sequentially from top to bottom. The lower edge of the upper air guide plate 500 and the upper edge of the lower air guide plate 600 define the opening area 151 of the air outlet 150.

[0049] Therefore, the indoor unit 10 of this utility model adjusts the height and vertical dimension of the opening area 151 by adjusting the position of the two air guide plates, which improves the accuracy of adjusting the height and vertical dimension of the air outlet 150, better adapts to different air supply needs, and thus realizes directional air supply to users at different heights or in different positions, thereby improving the heat exchange efficiency of the indoor unit 10.

[0050] In some embodiments, such as Figures 6 to 14As shown, the two air guide plates have a diffuser position where the air outlet 150 is fully open to guide the airflow within the housing 100 to diffuse forward from the air outlet 150; a convergent position where only the middle region of the air outlet 150 is open to guide the airflow within the housing 100 to converge forward from the open region 151; an upward blowing position where only the upper region of the air outlet 150 is open to guide the airflow within the housing 100 to tilt forward and upward from the open region 151; and a downward blowing position where only the lower region of the air outlet 150 is open to guide the airflow within the housing 100 to tilt forward and downward from the open region 151. In other words, the two air guide plates have a diffuser position, a convergent position, an upward blowing position, and a downward blowing position. Additionally, the two air guide plates also have a closed position where the air outlet 150 is completely closed.

[0051] In this embodiment, each air guide plate can be moved independently and controlled to switch between a dispersing position, a concentrating position, an upward blowing position, and a downward blowing position. Thus, the two air guide plates can slide opposite each other or towards each other to switch between these positions. Therefore, the indoor unit 10 of this embodiment of the air conditioner achieves multiple forms of axial flow air delivery by adjusting the positions of the two air guide plates.

[0052] Therefore, in this embodiment of the air conditioner indoor unit 10, two air guide plates are slidably arranged in the air outlet 150, facing away from or towards each other. They have a diffused air position, a concentrated air position, an upward blowing position, a downward blowing position, and a closed position. The two air guide plates can switch between the diffused air position, the concentrated air position, the upward blowing position, the downward blowing position, and the closed position, realizing the switching of multiple air supply modes such as forward diffusion, forward convergence, upward blowing, and downward blowing. This achieves multi-form axial flow air supply, avoids the problem of a single air supply mode, and improves the heat exchange effect of the air conditioner indoor unit 10, thereby improving the user experience.

[0053] In some embodiments, such as Figure 1 As shown, the housing 100 of the indoor unit 10 of the air conditioner in this embodiment of the present invention is a horizontally extending column. Additionally, as... Figure 1 As shown, the air outlet 150 is located at the vertical center of the front side of the housing 100 and extends horizontally in the shape of a strip. That is to say, the size of the housing 100 of the indoor unit 10 in the left-right direction is larger than the size of the housing 100 in the up-down direction, and the size of the air outlet 150 in the left-right direction of the housing 100 is larger than the size of the air outlet 150 in the up-down direction of the housing 100.

[0054] Therefore, the air conditioner indoor unit 10 of this utility model, by opening a horizontally extending and strip-shaped air outlet 150 in the vertical center of the front side of the horizontally extending housing 100, achieves a shape matching setting between the air outlet 150 and the housing 100, improving the appearance uniformity and aesthetics of the front panel 130. Simultaneously, the air outlet 150 being located in the vertical center of the front side of the housing 100 enables forward airflow from the center. Compared to the traditional forward and downward airflow scheme, this improves the adjustability of the airflow angle and the maximum airflow distance, helping the heat exchange airflow reach farther areas to more evenly cover the room, thereby improving the uniformity of heat exchange airflow distribution in the room, and thus improving the heat exchange uniformity of the air conditioner indoor unit 10.

[0055] In some embodiments, such as Figures 1-3 and Figures 5 to 14 As shown, the housing 100 includes a rear cover 110, an air outlet frame 120, and a front panel 130 arranged sequentially in the front-to-back direction. Specifically, the rear cover 110, the air outlet frame 120, and the front panel 130 are sequentially connected and fixed in the front-to-back direction of the housing 100. Furthermore, the rear cover 110 has an air inlet 140, the front panel 130 is a vertically arranged flat plate, and the air outlet 150 is located in the vertical center of the front panel 130, so that the airflow at the air outlet 150 tends to blow forward. Therefore, the air inlet and outlet direction of the indoor unit 10 of this embodiment is rear air inlet and front air outlet.

[0056] In one specific embodiment, such as Figure 2 As shown, the air inlet 140 includes a plurality of air inlet holes 141 spaced apart on the outer peripheral side of the rear cover 110, so that airflow can enter the housing 100 from various directions at the rear of the housing 100. Specifically, the plurality of air inlets 140 can be evenly spaced apart on the outer peripheral side of the rear cover 110 to improve the uniformity of airflow distribution entering the housing 100 and reduce eddies and turbulence in the airflow inside the housing 100, thereby improving the stability and efficiency of the airflow.

[0057] Therefore, the air conditioner indoor unit 10 of this utility model, by opening multiple air inlets 141 on the outer periphery of the rear cover 110, can increase the air intake area and improve air intake efficiency compared with the traditional single air inlet 140 design. At the same time, it effectively disperses the impact force when the airflow enters the housing 100, reduces the generation of noise, and thus improves the user's comfort and user experience.

[0058] In some embodiments, such as Figure 1As shown, the front panel 130 has a horizontally open center section in the vertical middle to form an air outlet 150, so that the airflow at the air outlet 150 tends to blow horizontally forward. Thus, in the air conditioner indoor unit 10 of this embodiment, the front panel 130 is arranged in a vertically and horizontally symmetrical manner, which improves the appearance of the air conditioner indoor unit 10.

[0059] In some embodiments, such as Figures 5-9 As shown, each air guide plate is a vertically arranged flat plate, and both air guide plates are attached to the side of the front panel 130 adjacent to the air outlet frame 120 and are located on the upper and lower sides of the air outlet 150, respectively. That is to say, the upper air guide plate 500 and the lower air guide plate 600 are both located inside the housing, further improving the appearance of the indoor unit 10 of the air conditioner. Specifically, each air guide plate is a horizontally extending strip-shaped flat plate.

[0060] Therefore, in the air conditioner indoor unit 10 of this embodiment, the horizontally extending air guide plate matches the shape and design style of the horizontally extending columnar shell 100, improving the uniformity and aesthetics of the front panel 130. Furthermore, while achieving vertical airflow direction adjustment, the adjustment range of the air supply in the left-right direction of the shell 100 is maximized, optimizing the uniformity of heat exchange airflow distribution, improving comfort and energy efficiency, and simultaneously considering aesthetics and practicality. It is particularly suitable for scenarios requiring zoned air supply, large spaces, or high ceilings.

[0061] In some embodiments, such as Figures 2 to 14 As shown, the central axis of each axial fan 200 extends horizontally and is arranged parallel to the front-rear direction of the housing 100. That is to say, the air outlet direction of each axial fan 200 is horizontally forward along the front-rear direction of the housing 100.

[0062] Therefore, in the indoor unit 10 of this utility model, each axial fan 200 blows air forward, realizing that the airflow inside the casing 100 has a tendency to flow forward and blow out from the air outlet 150. Compared with the traditional forward and downward air outlet scheme, it improves the adjustability of the air supply angle and the maximum air supply distance, which helps the heat exchange airflow reach a farther area to cover the room more evenly, thereby improving the uniformity of the heat exchange airflow distribution in the room, and thus improving the heat exchange uniformity of the indoor unit 10.

[0063] In some embodiments, such as Figures 3-5 As shown, the indoor unit 10 of the air conditioner may include a plurality of axial flow fans 200. The plurality of axial flow fans 200 are arranged at intervals in the left-right direction of the housing 100 so that the airflow inside the housing 100 is blown forward under the action of the plurality of axial flow fans 200.

[0064] Therefore, multiple axial flow fans 200 arranged at intervals in the left and right directions can operate simultaneously, which improves the uniformity and volume of air supply in the left and right directions of the indoor unit 10 while achieving synchronous forward air supply in the left and right directions, thereby increasing the overall air supply volume and heat exchange effect of the indoor unit 10.

[0065] In one specific embodiment, such as Figure 5 As shown, the rotation direction of each axial fan 200 is opposite to that of the adjacent axial fan 200, so that the airflow blown out by the multiple axial fans 200 can converge in front of the housing 100.

[0066] Therefore, when multiple axial flow fans 200 rotate in opposite directions adjacent to each other, the airflow generated by every two adjacent axial flow fans 200 will interact and overlap within the indoor unit 10 of the air conditioner, enhancing airflow turbulence and mixing, thereby improving the airflow circulation efficiency and uniformity within the indoor unit 10. Furthermore, the counter-rotation of every two adjacent axial flow fans 200 reduces the collision and cancellation of airflows when they meet, lowering the overall noise level of the indoor unit 10 while increasing the air delivery distance of each axial flow fan 200. This facilitates the convergence of airflows from multiple axial flow fans 200 in front of the casing 100, further improving the air delivery effect of the indoor unit 10.

[0067] In some embodiments, such as Figures 3-5 As shown, in the indoor unit 10 of this utility model, there are two axial flow fans 200. Specifically, the two axial flow fans 200 are symmetrically arranged in the left-right direction of the housing 100, and the central axes of the two axial flow fans 200 are parallel.

[0068] As a result, the airflow from the two axial fans 200 converges at the front center of the housing 100. In addition, the two axial fans 200 rotate in opposite directions, so that the airflow from multiple axial fans 200 converges at the front of the housing 100, thereby improving the air supply effect of the indoor unit 10.

[0069] In one specific embodiment, such as Figure 5 As shown, when the upper air guide plate 500 and the lower air guide plate 600 are in the closed position, the lower edge of the upper air guide plate 500 is in contact with the upper edge of the lower air guide plate 600. As a result, the air outlet 150 is completely closed, so that the front appearance of the air conditioner indoor unit 10 has continuity, thereby improving the overall aesthetics of the air conditioner indoor unit 10.

[0070] like Figure 6As shown, when the upper air guide plate 500 and the lower air guide plate 600 are in the air dispersion position, they are completely retracted into the casing, thus fully opening the air outlet 150. Consequently, under the action of the axial flow fan 200, the airflow inside the casing diffuses forward through the open area 151 and is blown out over a wide area, achieving the air dispersion and distribution mode of the indoor unit 10.

[0071] like Figure 7 As shown, when the upper air guide plate 500 and the lower air guide plate 600 are in the air-gathering position, the upper air guide plate 500 and the lower air guide plate 600 slide towards each other so that the vertical dimension of the opening area 151 is smaller than the vertical dimension of the air outlet 150, and the upper air guide plate 500 and the lower air guide plate 600 are symmetrically arranged in the vertical direction of the housing. Thus, the opening area 151 is the central area of ​​the air outlet 150. Under the action of the axial flow fan 200, the airflow inside the housing converges and flows forward through the narrow opening area 151 and is blown out at high speed to achieve the air-gathering and air-dissipating form of the air conditioning indoor unit 10.

[0072] like Figure 8 As shown, when the upper air guide plate 500 and the lower air guide plate 600 are in the upward blowing position, the vertical dimension of the opening area 151 defined between the upper air guide plate 500 and the lower air guide plate 600 is smaller than the vertical dimension of the air outlet 150, and the opening area 151 is the upper region of the air outlet 150. Therefore, under the action of the axial flow fan 200, the airflow inside the casing flows towards the opening area 151 located at the upper part of the casing, thus forming a forward and upward air outlet direction, which is then blown upward at an angle from the opening area 151, thereby achieving the upward blowing airflow pattern of the indoor unit 10 of the air conditioner.

[0073] like Figure 9 As shown, when the upper air guide plate 500 and the lower air guide plate 600 are in the downward blowing position, the vertical dimension of the opening area 151 defined between the upper air guide plate 500 and the lower air guide plate 600 is smaller than the vertical dimension of the air outlet 150, and the opening area 151 is the lower region of the air outlet 150. Therefore, under the action of the axial flow fan 200, the airflow inside the casing flows towards the opening area 151 located at the lower part of the casing, thus forming a forward and downward airflow direction, which is then blown downwards at an angle from the opening area 151, thereby achieving the downward blowing airflow pattern of the indoor unit 10 of the air conditioner.

[0074] Therefore, in the air conditioner indoor unit 10 of this utility model embodiment, the upper air guide plate 500 and the lower air guide plate 600 have a closed position, a diffused air position, a concentrated air position, an upward blowing position, and a downward blowing position, and can switch between multiple air supply positions, realizing the switching of multiple air supply forms such as forward diffusion, forward convergence, upward blowing, and downward blowing, thereby realizing multi-form axial flow air supply, avoiding the problem of single air supply form, thereby improving the heat exchange effect of the air conditioner indoor unit 10, and thus improving the user experience.

[0075] In some embodiments, such as Figures 10-14 As shown, each air guide plate includes a vertically arranged plate body (not shown in the figure), and each plate body is a vertically arranged flat plate. Specifically, the plates of both air guide plates are attached to the side of the front panel 130 adjacent to the air outlet frame 120 and are respectively located on the upper and lower sides of the air outlet 150. For example, the upper air guide plate 500 includes a vertically arranged upper plate body 510, and the lower air guide plate 600 includes a vertically arranged lower plate body 610. The upper plate body 510 and the lower plate body 610 are both attached to the upper and lower sides of the air outlet 150 facing the inside of the housing, and the lower edge of the upper plate body 510 and the upper edge of the lower plate body 610 define the opening area 151 of the air outlet 150.

[0076] Furthermore, such as Figures 10-14 As shown, each air guide plate also includes a guide vane extending backward at an angle from one side edge of the plate body near the center of the air outlet 150 toward the center of the air outlet 150, and the guide vanes of the two air guide plates are used to guide the airflow within the housing 100 toward the air outlet 150. That is, the air guide plate is composed of a plate body and a guide vane in a V-shaped structure. For example, the upper air guide plate 500 includes an upper guide vane 520, and the lower air guide plate 600 includes a lower guide vane 620. The upper guide vane 520 extends upward and backward at an angle from the lower edge of the upper plate body 510, and the lower guide vane 620 extends downward and backward at an angle from the upper edge of the lower plate body 610, so as to guide the airflow within the housing 100 to converge toward the air outlet 150.

[0077] Therefore, by setting a guide plate on one side of the panel adjacent to the inner side of the casing to form a V-shaped air guide plate, the air outlet resistance is reduced to a certain extent, while the air outlet angle of the airflow inside the casing is increased from the air outlet 150.

[0078] In some embodiments, such as Figures 10-14As shown, two horizontally extending baffles 122 are respectively provided at the upper and lower ends of the side of the air outlet frame 120 adjacent to the front panel 130, so as to form a storage space for accommodating the air guide plate. Specifically, during the sliding process of the air guide plate, the rear end of the air guide plate is fitted with the baffle 122 to limit the displacement of the air guide plate in the front-rear direction of the housing 100, thereby improving the structural stability of the air conditioner indoor unit 10.

[0079] In some embodiments, such as Figures 1-3 , Figures 5 to 14 As shown, the indoor unit 10 of the air conditioner may further include a heat exchanger 300. Specifically, the heat exchanger 300 is disposed within the housing 100, located between the axial fan 200 and the air outlet 150, and is used for heat exchange with the airflow blown out by the axial fan 200. In a specific embodiment, a mounting member 121 for mounting and fixing the heat exchanger 300 is provided inwardly on the air outlet frame 120, so that the heat exchanger 300 is disposed within the air outlet frame 120. That is, the heat exchanger 300 is disposed between the axial fan 200 and the air outlet 150. Thus, the airflow entering the housing 100 from the air inlet 140 can fully contact the heat exchanger 300 under the action of the axial fan 200 and then be blown out through the air outlet 150.

[0080] Therefore, the indoor unit 10 of this utility model, while achieving downward tilted airflow, avoids the problems of insufficient contact between the incoming airflow and the heat exchanger 300, uneven heat exchange, and excessive noise caused by directly placing the axial fan 200 at the air outlet 150. It ensures that the airflow in the indoor unit 10 has fully entered the internal space of the indoor unit 10 before being driven by the axial fan 200 through the heat exchanger 300, thereby increasing the contact time and uniformity between the airflow and the heat exchanger 300, thus improving the heat exchange efficiency of the indoor unit 10 and the heat exchange effect of the indoor unit 10.

[0081] In some embodiments, such as Figure 2 , Figures 5 to 14 As shown, the heat exchanger 300 is a vertically extending flat plate. The dimension of the heat exchanger 300 in the left-right direction of the housing 100 is larger than the dimension of the axial fan 200 in the left-right direction of the housing 100, and the dimension of the heat exchanger 300 in the vertical direction of the housing 100 is also larger than the dimension of the axial fan 200 in the vertical direction of the housing 100. Furthermore, an air outlet space 310 is defined between the side of the heat exchanger 300 away from the axial fan 200 and the housing 100. In other words, the heat exchanger 300 can be optionally designed as a straight-vent type and vertically installed within the housing to save space in the overall thickness of the indoor unit 10. The dimension of the heat exchanger 300 is larger than the projected dimension of the axial fan in the front-back direction of the housing, ensuring sufficient contact with the airflow blown by the axial fan 200 and improving heat exchange efficiency.

[0082] Therefore, in the indoor unit 10 of this utility model, the heat exchanger 300 is arranged perpendicularly to the central axis of the axial flow fan 200, achieving a match between the orientation of the heat exchanger 300 and the orientation of the multiple axial flow fans 200. This allows for a closer fit between the heat exchanger 300 and the multiple axial flow fans 200, reducing the distance between the airflow from each axial flow fan 200 and the heat exchanger 300, thereby improving the uniformity of airflow in the indoor unit 10 and further enhancing its heat exchange efficiency. Simultaneously, the heat exchanger 300 is vertically positioned within the casing, reducing the space it occupies within the indoor unit 10 and further optimizing the spatial layout.

[0083] In some embodiments, such as Figures 2 to 14 As shown, the indoor unit 10 of the air conditioner may also include a fan housing 400. The fan housing 400 is disposed inside the housing 100, located between the axial fan 200 and the heat exchanger 300, and is used to guide the airflow blown by the axial fan 200 toward the heat exchanger 300. That is, the fan housing 400 is fixedly disposed at the air outlet end of the axial fan 200, guiding the airflow blown by the axial fan 200 toward the surface of the heat exchanger 300 near the air outlet 150.

[0084] Specifically, the indoor unit 10 of the air conditioner includes a plurality of axial flow fans 200, and correspondingly, a plurality of separately arranged air outlet cavities 411 are defined between the fan housing 400 and the heat exchanger 300. The plurality of air outlet cavities 411 are arranged one-to-one with the plurality of axial flow fans 200, so that the airflow blown out by the plurality of axial flow fans 200 flows to the heat exchanger 300 respectively.

[0085] In one specific embodiment, the fan housing 400 may include a vertically extending and flat baffle 410, a plurality of annular fan mounting portions 420 that protrude rearward from the vertical center of the baffle 410 and are spaced apart in the left and right directions, and a strip partition 430 that is located between two adjacent fan mounting portions 420 and protrudes forward from the front side of the baffle 410.

[0086] In this embodiment, the fan mounting part 420 is used to install and fix the axial flow fan 200 so that the baffle 410 covers the outer periphery of the air outlet end of the axial flow fan 200. Thus, the baffle 410, the partition 430 located between two adjacent axial flow fans 200, the heat exchanger 300, and the housing 100 can be enclosed to form a plurality of air outlet chambers 411 corresponding to each axial flow fan 200, so that each axial flow fan 200 corresponds to an independent air outlet chamber 411.

[0087] For example, such as Figure 4As shown, the indoor unit 10 of the air conditioner may include two axial flow fans 200. Correspondingly, the fan housing 400 may include a baffle 410, two fan mounting portions 420 symmetrically arranged in the left-right direction of the baffle 410, and a strip partition 430 located in the transverse middle of the baffle 410, so as to define two air outlet chambers 411 corresponding to the two axial flow fans 200 between the baffle 410 and the heat exchanger 300, so that the airflow blown out by the two axial flow fans 200 flows to the heat exchanger 300 respectively.

[0088] Therefore, in the indoor unit 10 of this utility model embodiment, the fan housing 400 ensures that the airflow blown by each axial fan 200 flows directly and orderly to different areas of the heat exchanger 300 through the separately arranged air outlet cavities 411, reducing airflow turbulence and energy loss. At the same time, the directional airflow helps to enhance the convective heat transfer coefficient of the heat exchanger 300 surface, thereby improving the overall heat exchange efficiency of the indoor unit 10. In addition, the airflow inside the indoor unit 10 is guided by the fan housing 400, resulting in a more uniform distribution on the surface of the heat exchanger 300, avoiding local overheating or overcooling, and thus improving heat exchange uniformity.

Of course, in other optional embodiments, the air conditioner indoor unit 10 of this invention can also be a cabinet-type air conditioner indoor unit.
