Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an embedded air-conditioning indoor unit with upper and lower air intakes. Background Art

[0002] In the trend toward integrated homes, appliances like refrigerators and dishwashers have successfully achieved embedded installation, seamlessly blending into the home environment. Air conditioners, as major appliances in the living room, also need to follow this trend. Embedded designs allow cabinet air conditioners to be "hidden" within the home, not only enhancing overall aesthetics but also better meeting the modern family's demand for minimalist, uncluttered spaces. This integrated design not only optimizes space utilization but also enhances a sense of harmony and comfort in the home. Because all sides of embedded air conditioners except the front are obscured by furniture and / or walls, existing embedded air conditioners typically feature both an inlet and outlet on the front to ensure smooth airflow.

[0003] However, built-in air conditioners currently on the market typically only have one air inlet located at the lower front of the indoor unit and one air outlet located at the upper front of the indoor unit. The lower front air inlet is easily blocked by furniture, carpets, or debris on the floor, resulting in poor air flow and impacting the efficiency of the built-in air conditioner. Furthermore, with only one air inlet located below the air outlet, during cooling mode operation, the incoming airflow is often composed of cooler air after heat exchange, making it difficult for the cooler air above the room to enter the indoor unit, seriously affecting the uniformity of the indoor temperature. Utility Model Content

[0004] In view of the above problems, the present invention proposes an air-conditioning indoor unit that overcomes the above problems or at least partially solves the above problems.

[0005] One purpose of the present invention is to provide an air-conditioning indoor unit that can improve the uniformity of indoor temperature, thereby improving the user experience.

[0006] A further object of the present invention is to improve air intake efficiency.

[0007] Another further object of the present invention is to improve heat exchange efficiency.

[0008] In particular, the utility model provides an air conditioner indoor unit, comprising:

[0009] The housing includes a front panel having an air outlet and a first air inlet and a second air inlet located on upper and lower sides of the air outlet; and

[0010] The fan assembly is arranged in the casing and is used to guide the indoor air flow from the first air inlet and the second air inlet to flow into the casing and be sent out through the air outlet.

[0011] Furthermore, the fan assembly includes:

[0012] a first air inlet fan disposed in the housing adjacent to the first air inlet and configured to guide indoor air flow from the first air inlet into the housing; and

[0013] The second air inlet fan is arranged in the casing at a position adjacent to the second air inlet, and is used for guiding the indoor air flow to flow into the casing from the second air inlet.

[0014] Furthermore, the fan assembly includes:

[0015] an air duct member disposed in the housing near the air outlet, for dividing the space in the housing into an air inlet cavity communicating with the air inlet and an air outlet cavity communicating with the air outlet, and an opening is provided on the air duct member to connect the air inlet cavity and the air outlet cavity; and

[0016] An air outlet fan, located in the air outlet cavity, is used to guide the airflow in the air inlet cavity into the air outlet cavity and send it out through the air outlet; and

[0017] The air conditioner indoor unit also includes a heat exchanger, which is arranged on the air duct and located in the air inlet cavity, and is used to exchange heat with the air flowing into the air inlet cavity.

[0018] Furthermore, the upper and lower ends of the air duct member are respectively spaced apart from the casing.

[0019] Furthermore, the air outlet fan is a cross-flow fan, and the rotation axis of the air outlet fan is arranged vertically.

[0020] Furthermore, the heat exchanger is arranged around a portion of the outer periphery of the air outlet fan.

[0021] Furthermore, the air conditioner indoor unit also includes:

[0022] A plurality of swing blades are rotatably disposed in the air outlet cavity adjacent to the air outlet, and the plurality of swing blades are evenly spaced apart in the vertical direction; and

[0023] The driving mechanism is used to drive the swing blades to rotate to adjust the air outlet direction of the air outlet.

[0024] Furthermore, the dimensions of the first air inlet and the second air inlet in the left-right direction of the front panel are both 0.7 to 0.9 times the dimension of the front panel in the left-right direction; and / or

[0025] The size of the first air inlet in the vertical direction of the front panel is 1 to 3 times the size of the second air inlet in the vertical direction of the front panel.

[0026] Furthermore, the air conditioner indoor unit also includes:

[0027] A first air inlet cover is rotatably disposed at the first air inlet and is used to open or close the first air inlet;

[0028] a second air inlet cover, rotatably disposed at the second air inlet, for opening or closing the second air inlet; and

[0029] The air outlet cover is rotatably arranged at the air outlet and is used to open or close the air outlet.

[0030] Furthermore, the air conditioner indoor unit is placed in the receiving cavity of the household appliance.

The upper and lower air inlet form of the air conditioner indoor unit of the present invention effectively avoids the problem of poor air intake that is easy to occur in the lower air inlet form. At the same time, the air conditioner indoor unit of the present invention can achieve air intake from both the upper and lower sides of the air outlet, avoiding the problem of insufficient participation of the air in the upper or lower side of the room in heat exchange due to the provision of a single air inlet on one side of the upper and lower sides of the air outlet, thereby improving the heat exchange efficiency of the indoor air, thereby improving the uniformity of the indoor temperature, and further improving the user experience.

[0032] Furthermore, in the air conditioner indoor unit of the present invention, the fan assembly may include a first air inlet fan and a second air inlet fan, wherein the first air inlet fan is disposed within the housing adjacent to the first air inlet and is configured to guide indoor airflow from the first air inlet into the housing, and the second air inlet fan is disposed within the housing adjacent to the second air inlet and is configured to guide indoor airflow from the second air inlet into the housing. Thus, the air inlet fans are disposed at both the first and second air inlets, greatly improving the air intake efficiency of the first and second air inlets, thereby improving the overall air intake efficiency of the air conditioner indoor unit and further improving the heat exchange efficiency of the indoor air.

[0033] Furthermore, in the air conditioner indoor unit of the present invention, the fan assembly may further include a duct member and an outlet fan. The duct member is disposed in the housing near the air outlet, and is used to divide the space in the housing into an air inlet chamber connected to the air inlet and an air outlet chamber connected to the air outlet. The outlet fan is located in the air outlet chamber, and is used to guide the air flow in the air inlet chamber to flow into the air outlet chamber and be sent out through the air outlet. The heat exchanger of the air conditioner indoor unit is disposed on the duct member and is located in the air inlet chamber, and is used to exchange heat with the air flow flowing into the air inlet chamber.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present invention to those skilled in the art.

[0041] Figure 1 It is a structural diagram of an air-conditioning indoor unit 1 in an embedded installation state according to an embodiment of the present invention. Figure 2 It is an exploded diagram of a partial structure of an air-conditioning indoor unit 1 according to an embodiment of the present invention. Figure 3 It is a cross-sectional schematic diagram of an air-conditioning indoor unit 1 according to an embodiment of the present invention. Figure 4 1 is a schematic structural diagram of an air-conditioning indoor unit 1 according to an embodiment of the present invention, wherein the air inlet cover, the air outlet cover 17 and part of the housing 10 are omitted to illustrate the internal structure thereof.

[0042] like Figure 1 As shown, the air-conditioning indoor unit 1 of the embodiment of the present invention can be embedded in a household appliance 2. Specifically, the air-conditioning indoor unit 1 is placed in a receiving cavity (not shown in the figure) of the household appliance 2. It should be noted that the air-conditioning indoor unit 1 is installed and fixed in the household appliance 2, and is connected to the air-conditioning outdoor unit through a refrigerant pipe, thereby ensuring the stable operation of the air-conditioning system and efficient cooling or heating effects. In addition, the household appliance 2 can be an independent piece of furniture, a connected piece of furniture, or a piece of furniture integrated with a building, and the air-conditioning indoor unit 1 is embedded in the household appliance 2. The air-conditioning indoor unit 1 is completely contained in the interior of the household appliance 2, thereby improving the space utilization rate of the user's room, and also making the air-conditioning and the home environment perfectly integrated, thereby improving the overall aesthetics.

[0043] In one specific embodiment, the air conditioner indoor unit 1 is placed within the housing cavity of a household appliance 2, and the front panel 11 of the housing 10 is coplanar with the front panel 21 of the household appliance 2. After the air conditioner indoor unit 1 is embedded in the household appliance 2, only the front panel 11 of the indoor unit is visible from the outside of the household appliance 2. Therefore, arranging the front panel 11 of the air conditioner indoor unit 1 coplanar with the front panel 21 of the household appliance 2 not only enhances the overall aesthetics of the home environment but also reduces visual intrusion.

[0044] Specifically, the front panel 11 can adopt materials and colors that match the household appliance 2, so that it is consistent with the overall home style, making the air conditioner a part of the home environment, further improving the overall aesthetics of the home environment, and thus improving the user experience.

[0045] In some embodiments, as Figure 2 As shown, the air-conditioning indoor unit 1 according to the embodiment of the present invention may generally include a casing 10 and a fan assembly 20 .

[0046] The housing 10 includes a front panel 11 having an air outlet 12 and a first air inlet 13 and a second air inlet 14 located above and below the air outlet 12. The air outlet 12 is used to discharge conditioned air within the housing 10 into the indoor environment to condition the indoor air. The conditioned airflow can be heat exchange airflow, humidification airflow, water washing airflow, fresh air flow, etc.

[0047] The fan assembly 20 is disposed in the housing 10 and is used to guide indoor air flow from the first air inlet 13 and the second air inlet 14 into the housing 10 and out through the air outlet 12 .

[0048] The air conditioner indoor unit 1 of the present embodiment has an air outlet 12 and a first air inlet 13 and a second air inlet 14 located above and below the air outlet 12, respectively, on the front panel 11 of its housing 10. A fan assembly 20 is disposed within the housing 10 to guide indoor airflow from the first air inlet 13 and the second air inlet 14 into the housing 10 and out through the air outlet 12, thereby forming an air inlet and outlet configuration with both upper and lower air intake and central air outlet, allowing air to enter from both the upper and lower sides of the air outlet 12. The upper and lower air intake configuration of the air conditioner indoor unit 1 of the present embodiment effectively avoids the problem of poor air intake, which is often encountered with lower air intake configurations. Furthermore, the air conditioner indoor unit 1 of the present embodiment can achieve air intake from both the upper and lower sides of the air outlet 12, avoiding the problem of insufficient heat exchange between the upper and lower air in the room caused by providing a single air inlet on one side of the upper and lower sides of the air outlet 12. This improves the heat exchange efficiency of the indoor air, thereby increasing the uniformity of the indoor temperature and further enhancing the user experience.

[0049] In some embodiments, as Figure 1 and Figure 2 As shown, the air conditioner indoor unit 1 of the present embodiment may further include a first air inlet cover 15, a second air inlet cover 16, and an air outlet cover 17. The first air inlet cover 15 is rotatably disposed at the first air inlet 13 for opening or closing the first air inlet 13. The second air inlet cover 16 is rotatably disposed at the second air inlet 14 for opening or closing the second air inlet 14. The air outlet cover 17 is rotatably disposed at the air outlet 12 for opening or closing the air outlet 12.

[0050] Specifically, the air outlet 12 can be a rectangular opening whose length direction is parallel to the vertical direction of the front panel 11, and the first air inlet 13 and the second air inlet 14 can both be rectangular openings whose length direction is parallel to the horizontal direction of the front panel 11. Accordingly, the air outlet cover 17, the first air inlet cover 15, and the second air inlet cover 16 can each be a rectangular plate whose length direction is parallel to the vertical direction of the front panel 11. Furthermore, the number of the first air inlet cover 15, the second air inlet cover 16, and the air outlet cover 17 can each be one or more. In one specific embodiment, a plurality of first air inlet covers 15 are arranged along the horizontal direction of the front panel 11 at the first air inlet 13, a plurality of second air inlet covers 16 are arranged along the horizontal direction of the front panel 11 at the second air inlet 14, and a plurality of air outlet covers 17 are arranged along the horizontal direction of the front panel 11 at the air outlet 12.

[0051] When the air conditioner indoor unit 1 is started, the first air inlet cover 15, the second air inlet cover 16, and the air outlet cover 17 are all opened to allow indoor air to flow into the casing 10 from the first air inlet 13 and the second air inlet 14 and be discharged through the air outlet 12. When the air conditioner indoor unit 1 is stopped, the first air inlet cover 15, the second air inlet cover 16, and the air outlet cover 17 are all closed to avoid the problem of an untidy appearance of the front panel 11 and poor safety caused by the open first air inlet 13, the second air inlet 14, and the air outlet 12, thereby improving the user experience.

[0052] In addition, the first air inlet cover 15, the second air inlet cover 16 and the air outlet cover 17 can all be made of materials and colors that match the household appliance 2, so that they are consistent with the overall home style, and the first air inlet 13, the second air inlet 14 and the air outlet 12 of the air conditioner are all integrated into the overall home environment, further improving the overall aesthetics of the home environment, thereby improving the user experience.

[0053] In some embodiments, as Figure 2 and Figure 3 As shown, the fan assembly 20 may include a duct member 100 and an air outlet fan 200 .

[0054] like Figure 3 As shown, the duct member 100 is disposed within the housing 10 near the air outlet 12, and is used to divide the space within the housing 10 into an air inlet chamber 110 connected to the air inlet and an air outlet chamber 120 connected to the air outlet 12. The duct member 100 is provided with a plurality of openings 130 to connect the air inlet chamber 110 and the air outlet chamber 120. An air outlet fan 200 is located within the air outlet chamber 120, and is used to guide the airflow within the air inlet chamber 110 into the air outlet chamber 120 and out through the air outlet 12.

[0055] In addition, if Figure 3As shown, the air conditioner indoor unit 1 may further include a heat exchanger 30, which is disposed on the air duct member 100 and located within the air inlet cavity 110, and is configured to perform heat exchange on the airflow flowing into the air inlet cavity 110. In other words, the heat exchanger 30 is disposed upstream of the outlet fan 200. The airflow after heat exchange in the heat exchanger 30 flows into the outlet cavity 120 under the action of the outlet fan 200 and is discharged through the air outlet 12 to adjust the indoor temperature.

[0056] In the air-conditioning indoor unit 1 of the embodiment of the present invention, the fan assembly 20 may further include a duct member 100 and an air outlet fan 200. The duct member 100 is arranged at a position adjacent to the air outlet 12 in the casing 10, and is used to divide the space in the casing 10 into an air inlet cavity 110 connected to the air inlet and an air outlet cavity 120 connected to the air outlet 12. The air outlet fan 200 is located in the air outlet cavity 120, and is used to guide the airflow in the air inlet cavity 110 to flow into the air outlet cavity 120 and be sent out through the air outlet 12. The heat exchanger 30 of the air-conditioning indoor unit 1 is arranged on the duct member 100 and is located in the air inlet cavity 110, and is used to exchange heat for the airflow flowing into the air inlet cavity 110. Thus, the airflow entering the casing 10 from the first air inlet 13 and the second air inlet 14 can enter the air inlet chamber 110 and the air outlet chamber 120 in an orderly manner under the guidance of the air duct 100, thereby improving the smoothness of the airflow. In addition, the airflow can fully contact with the heat exchanger 30 in the air inlet chamber 110, thereby improving the heat exchange efficiency of the incoming airflow, and further improving the heat exchange efficiency of the indoor air.

[0057] In some embodiments, as Figure 3 As shown, the heat exchanger 30 is disposed around a portion of the outer periphery of the air outlet fan 200. Specifically, as Figure 3 As shown, the heat exchanger 30 can be a U-shaped plate structure, with its opening 130 facing the outlet fan 200, forming a semi-enclosed annular structure. As a result, the airflow within the air inlet cavity 110 must pass through the surface of the heat exchanger 30 before flowing to the outlet fan 200. This ensures sufficient contact between the airflow within the air inlet cavity 110 and the heat exchanger 30, thereby increasing the contact area between the airflow within the air inlet cavity 110 and the surface of the heat exchanger 30, thereby improving heat exchange efficiency and enhancing the cooling or heating effect.

[0058] Furthermore, the air outlet fan 200 is a cross-flow fan, and the rotation axis of the air outlet fan 200 is vertically arranged. Therefore, the air outlet fan 200 can attract the airflow located on its outer peripheral side to flow in along its radial direction and blow it out along its radial direction. Figure 3As shown, the air inlet chamber 110 is disposed at least on the left and right sides and the rear periphery of the air outlet chamber 120. Driven by the air outlet fan 200, the airflow flowing into the air inlet chamber 110 from the first air inlet 13 and the second air inlet 14 can flow into the air outlet chamber 120 in the radial direction of the air outlet fan 200 and be blown out of the air outlet chamber 120 in the radial direction of the air outlet fan 200.

[0059] In the air-conditioning indoor unit 1 of the embodiment of the present invention, the air outlet fan 200 is configured as a cross-flow fan, which reduces the occupied space while ensuring the largest possible air volume, improves the air outlet efficiency, and further improves the heat exchange efficiency of the indoor air.

[0060] In some embodiments, as Figure 4 As shown, the upper and lower ends of the air duct member 100 are spaced apart from the housing 10. Specifically, as Figure 4 As shown, the upper and lower ends of the duct member 100 are hollow, forming an air inlet channel 140. Consequently, the spaces within the housing 10 located on the upper and lower sides of the duct member 100, as well as the spaces located on the left, right, and rear sides of the duct member 100, are completely connected, forming a portion of the air inlet cavity 110. In other words, the air inlet cavity 110 surrounds the outer periphery of the air outlet cavity 120 at its upper and lower sides, left and right sides, and rear sides.

[0061] In addition, if Figure 2 As shown, the air-conditioning indoor unit 1 of the present invention can also be provided with a mounting member 700 in the casing, which is provided at the lower end of the duct member 100 to support the lower end of the duct member 100 to improve the structural stability. The mounting member 700 is at least partially hollow, so that the space where the air inlet cavity 110 is located on the lower side of the air supply duct member 100 can be connected to the space where the air inlet cavity 110 is located on the rear side of the air supply duct member 100 via the air inlet channel 140.

[0062] Therefore, sufficient air intake space is provided in the casing 10 of the air-conditioning indoor unit 1 of the embodiment of the utility model, thereby ensuring the air intake efficiency, and the surround-type air intake method improves the heat exchange efficiency between the air flow in the air inlet cavity 110 and the heat exchanger 30, thereby further improving the heat exchange efficiency of the air-conditioning indoor unit 1, and thus improving the user experience.

[0063] In some embodiments, as Figure 1 As shown, the fan assembly 20 may include a first air intake fan 300 and a second air intake fan 400 .

[0064] The first air inlet fan 300 is disposed in the housing 10 adjacent to the first air inlet 13 and is configured to guide indoor air flow from the first air inlet 13 into the housing 10. The second air inlet fan 400 is disposed in the housing 10 adjacent to the second air inlet 14 and is configured to guide indoor air flow from the second air inlet 14 into the housing 10.

[0065] In the air conditioner indoor unit 1 according to the embodiment of the present invention, the fan assembly 20 may include a first air inlet fan 300 and a second air inlet fan 400. The first air inlet fan 300 is disposed in the casing 10 adjacent to the first air inlet 13 and is configured to guide indoor airflow from the first air inlet 13 into the casing 10. The second air inlet fan 400 is disposed in the casing 10 adjacent to the second air inlet 14 and is configured to guide indoor airflow from the second air inlet 14 into the casing 10. Thus, the provision of air inlet fans at both the first air inlet 13 and the second air inlet 14 greatly improves the air intake efficiency of the first air inlet 13 and the second air inlet 14, thereby improving the overall air intake efficiency of the air conditioner indoor unit 1 and further improving the heat exchange efficiency of the indoor air.

[0066] In some embodiments, as Figure 1 As shown, the dimensions of the first air inlet 13 and the second air inlet 14 in the left-right direction of the front panel 11 are both 0.7 to 0.9 times the left-right dimension of the front panel 11. In other words, the dimension L of the first air inlet 13 in the left-right direction of the front panel 11 and the dimension D of the second air inlet 14 in the left-right direction of the front panel 11 are the same, which improves the appearance of the first air inlet 13 and the second air inlet 14 on the front panel 11.

[0067] In addition, the dimension L of the first air inlet 13 in the left-right direction of the front panel 11 and the dimension D of the second air inlet 14 in the left-right direction of the front panel 11 are both 0.7 to 0.9 times the dimension d of the front panel 11 in the left-right direction. Specifically, the dimension L of the first air inlet 13 in the left-right direction of the front panel 11 and the dimension D of the second air inlet 14 in the left-right direction of the front panel 11 are both 0.8 to 0.9 times the dimension d of the front panel 11 in the left-right direction. In a specific embodiment, the dimension L of the first air inlet 13 in the left-right direction of the front panel 11 and the dimension D of the second air inlet 14 in the left-right direction of the front panel 11 are both 0.85 times the dimension d of the front panel 11 in the left-right direction.

[0068] Therefore, the first air inlet 13 and the second air inlet 14 can occupy a sufficiently large area on the front panel 11, thereby increasing the air inlet area of ​​the air-conditioning indoor unit 1, and further improving the overall air inlet efficiency of the air-conditioning indoor unit 1, so as to improve the heat exchange efficiency of the indoor air.

[0069] In addition, if Figure 1As shown, the dimension W of the first air inlet 13 in the vertical direction of the front panel 11 is 1 to 3 times the dimension H of the second air inlet 14 in the vertical direction of the front panel 11. Specifically, the dimension W of the first air inlet 13 in the vertical direction of the front panel 11 is 2 to 3 times the dimension H of the second air inlet 14 in the vertical direction of the front panel 11. In one specific embodiment, the dimension W of the first air inlet 13 in the vertical direction of the front panel 11 is 2.5 times the dimension H of the second air inlet 14 in the vertical direction of the front panel 11.

[0070] As a result, the first air inlet 13 located above the air outlet 12 can have a sufficiently large area, effectively ensuring air intake efficiency when air flow from below is blocked due to obstacles on the ground. At the same time, more airflow in the upper space of the room can enter the housing 10 for heat exchange, further improving the heat exchange efficiency of the indoor air, thereby improving the uniformity of the indoor temperature and enhancing the user experience.

[0071] In some embodiments, as Figure 2 As shown, the air conditioner indoor unit 1 may further include a plurality of swing blades 40 and a driving mechanism (not shown in the figure). The plurality of swing blades 40 are rotatably arranged in the air outlet cavity 120 at a position adjacent to the air outlet 12. Figure 2 As shown, multiple swing blades 40 are evenly spaced vertically. A drive mechanism is used to rotate the swing blades 40 to adjust the airflow direction of the air outlet 12. As a result, the air conditioner indoor unit 1 can discharge air in multiple directions, effectively expanding the airflow range and providing the air conditioner indoor unit 1 with a wide air supply range.

[0072] In a specific embodiment, the rotation axis of the swing blade 40 can be vertically arranged. Thus, the air outlet direction of the air outlet 12 can be adjusted left and right, so that the air conditioner indoor unit 1 can discharge air forward, left and right.

[0073] In another embodiment, the rotation axis of the swing blade 40 can also be arranged horizontally. Thus, the air outlet direction of the air outlet 12 can be adjusted up and down, so that the air conditioner indoor unit 1 can discharge air forward, upward and downward.

[0074] In the air-conditioning indoor unit 1 of the embodiment of the present invention, the air-conditioning indoor unit 1 may further include a plurality of swing blades 40 and a driving mechanism. The plurality of swing blades 40 are rotatably arranged at intervals in the air outlet cavity 120 at positions adjacent to the air outlet 12. The driving mechanism is used to drive the swing blades 40 to rotate to adjust the air outlet direction of the air outlet 12, thereby realizing more diversified air supply methods, thereby further improving the user experience.

These directions or positions are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as a limitation to the present invention.

[0076] The terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the definition of "first," "second," etc. may explicitly or implicitly include at least one of the features, that is, include one or more of the features.
