Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an embedded air conditioning indoor unit with top and bottom air intake. Background Technology

[0002] In the trend of integrated home furnishing, appliances such as refrigerators and dishwashers have successfully achieved built-in installation, perfectly blending into the home environment. As a major appliance in the living room, air conditioners also need to follow this trend. Built-in designs allow air conditioner units to be "hidden" in the home environment, not only improving overall aesthetics but also better meeting the modern family's demand for a simple and clean space. This integrated design not only optimizes space utilization but also enhances the harmony and comfort of the home. Since built-in air conditioners are obscured by furniture and / or walls on all sides except the front, existing built-in air conditioners typically have both an air inlet and an air outlet on the front to ensure smooth airflow.

[0003] However, most built-in air conditioners on the market today only have one air inlet on the lower front of the indoor unit and one air outlet on the upper front. The lower front air inlet is easily blocked by furniture, carpets, or debris on the floor, resulting in poor airflow and affecting the operating efficiency of the built-in air conditioner. Furthermore, having only one air inlet below the air outlet means that during cooling mode, the incoming airflow is mostly cooler air after heat exchange, making it difficult for cooler air from the upper part of the room to enter the indoor unit, severely affecting the uniformity of the indoor temperature. Summary of the Invention

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

[0005] One objective of this invention is to provide an indoor air conditioning unit that can improve indoor temperature uniformity, thereby enhancing the user experience.

[0006] A further objective of this invention is to improve air intake efficiency.

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

[0008] Specifically, the present invention provides an indoor unit for an air conditioner, comprising:

[0009] The casing includes a front panel, on which an air outlet is provided and a first air inlet and a second air inlet are located on the upper and lower sides of the air outlet, respectively; and

[0010] The fan assembly, located inside the casing, guides indoor airflow into the casing from the first and second air inlets and out through the air outlet.

[0011] Furthermore, the wind turbine components include:

[0012] A first air intake fan is located inside the casing near the first air inlet, used to guide indoor airflow from the first air inlet into the casing; and

[0013] The second air intake fan is located inside the casing near the second air inlet and is used to guide indoor airflow from the second air inlet into the casing.

[0014] Furthermore, the wind turbine components include:

[0015] An air duct component, located inside the casing near the air outlet, divides the space within the casing into an air inlet chamber communicating with the air inlet and an air outlet chamber communicating with the air outlet. The air duct component has an opening to allow communication between the air inlet and air outlet chambers.

[0016] The exhaust fan, located inside the exhaust cavity, guides the airflow from the intake cavity into the exhaust cavity and out through the exhaust port; and

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

[0018] Furthermore, the upper and lower ends of the air duct component are spaced apart from the housing.

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

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

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

[0022] Multiple swivel blades are rotatably positioned within the air outlet cavity near the air outlet, and these blades are evenly spaced vertically.

[0023] The drive mechanism is used to drive the blades to rotate, so as to adjust the air outlet direction.

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

[0025] The vertical dimension of the first air inlet on the front panel is 1 to 3 times the vertical dimension of the second air inlet on the front panel.

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

[0027] The first air inlet cover is rotatably mounted at the first air inlet and is used to open or close the first air inlet.

[0028] A second air inlet cover is rotatably mounted at the second air inlet for opening or closing the second air inlet; and

[0029] An air outlet cover is rotatably mounted at the air outlet for opening or closing the air outlet.

[0030] Furthermore, the indoor unit of the air conditioner is placed inside the cavity that houses the household appliance.

[0031] The indoor unit of this invention has an air outlet and a first air inlet and a second air inlet located on the upper and lower sides of the air outlet, respectively, on the front panel of its casing. A fan assembly is disposed inside the casing to guide indoor airflow into the casing from the first and second air inlets and out through the air outlet, forming an air intake and exhaust configuration where air can enter from both the upper and lower sides of the air outlet and exit from the center. This upper and lower air intake configuration effectively avoids the problem of poor airflow that easily occurs with lower air intake configurations. Simultaneously, the indoor unit of this invention allows air to enter from both the upper and lower sides of the air outlet, avoiding the problem of insufficient heat exchange on one side of the room due to a single air inlet on one side of the air outlet. This improves the heat exchange efficiency of the indoor air, thereby improving the uniformity of the indoor temperature and ultimately enhancing the user experience.

[0032] Furthermore, in the indoor unit of the air conditioner of the present invention, the fan assembly may include a first air intake fan and a second air intake fan. The first air intake fan is disposed inside the casing near the first air inlet and is used to guide indoor airflow from the first air inlet into the casing. The second air intake fan is disposed inside the casing near the second air inlet and is used to guide indoor airflow from the second air inlet into the casing. Thus, air intake fans are provided 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 indoor unit and further improving the heat exchange efficiency of the indoor air.

[0033] Furthermore, in the indoor unit of the air conditioner of the present invention, the fan assembly may further include a duct component and an outlet fan. The duct component is disposed within the casing near the air outlet, dividing the space within the casing into an air inlet chamber communicating with the air inlet and an air outlet chamber communicating with the air outlet. The outlet fan is located within the air outlet chamber, guiding the airflow in the air inlet chamber into the air outlet chamber and out through the air outlet. The heat exchanger of the indoor unit is disposed on the duct component and located within the air inlet chamber, for heat exchange of the airflow flowing into the air inlet chamber. Thus, the airflow entering the casing from the first and second air inlets can enter the air inlet chamber and air outlet chamber sequentially and orderly under the guidance of the duct component, improving the smoothness of airflow. In addition, the airflow can fully contact the heat exchanger within the air inlet chamber, thereby improving the heat exchange efficiency of the incoming airflow, and further improving the heat exchange efficiency of the indoor air.

While exemplary embodiments of the invention are shown in the drawings, it should be understood that the 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 invention to those skilled in the art.

[0041] Figure 1This is a schematic diagram of the structure of an air conditioner indoor unit 1 in an embedded installation state according to an embodiment of the present invention. Figure 2 This is an exploded disassembly diagram of a portion of the structure of an air conditioner indoor unit 1 according to an embodiment of the present invention. Figure 3 This is a cross-sectional schematic diagram of an indoor air conditioning unit 1 according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the structure of an indoor air conditioning unit 1 according to an embodiment of the present invention, wherein the air inlet cover, the air outlet cover 17 and part of the casing 10 are hidden to show its internal structure.

[0042] like Figure 1 As shown, the indoor unit 1 of the air conditioner in this embodiment of the invention can be embedded in a household appliance 2. Specifically, the indoor unit 1 is placed inside the receiving cavity (not shown in the figure) of the household appliance 2. It should be noted that the indoor unit 1 is installed and fixed in the household appliance 2 and connected to the outdoor unit of the air conditioner through a refrigerant pipe, ensuring the stable operation of the air conditioning system and efficient cooling or heating effect. In addition, the household appliance 2 can be a freestanding piece of furniture, a set of integrated furniture, or furniture integrated with the building. The indoor unit 1 is embedded in the household appliance 2, and the indoor unit 1 is completely accommodated inside the household appliance 2, which improves the space utilization of the user's room and makes the air conditioner perfectly integrated with the home environment, enhancing the overall aesthetics.

[0043] In one specific embodiment, the indoor unit 1 of the air conditioner is placed within the receiving cavity of the household appliance 2, and the front panel 11 of the casing 10 and the front panel 21 of the household appliance 2 are located on the same plane. After the 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, setting the front panel 11 of the indoor unit 1 to be on the same plane as the front panel 21 of the household appliance 2 not only improves the overall aesthetics of the home environment but also reduces visual obstruction.

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

[0045] In some embodiments, such as Figure 2 As shown, the indoor unit 1 of the air conditioner in this embodiment of the invention generally includes a housing 10 and a fan assembly 20.

[0046] The casing 10 includes a front panel 11, on which an air outlet 12 and a first air inlet 13 and a second air inlet 14 are respectively located on the upper and lower sides of the air outlet 12. The air outlet 12 is used to discharge the regulated airflow inside the casing 10 to the indoor environment to regulate the indoor air. The regulated airflow can be heat exchange airflow, humidification airflow, water washing airflow, fresh airflow, etc.

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

[0048] The air conditioner indoor unit 1 of this embodiment has an air outlet 12 and a first air inlet 13 and a second air inlet 14 located on the upper and lower sides of the air outlet 12, respectively. A fan assembly 20 is disposed inside 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, forming an air intake and exhaust pattern with airflow from both the upper and lower sides of the air outlet 12 and airflow from the middle. The upper and lower air intake pattern of the air conditioner indoor unit 1 of this embodiment effectively avoids the problem of poor airflow that easily occurs in the lower air intake pattern. At the same time, the air conditioner indoor unit 1 of this embodiment can achieve air intake from both the upper and lower sides of the air outlet 12, avoiding the problem of insufficient heat exchange on the upper or lower side of the room due to a single air inlet on one side of the air outlet 12, thus improving the heat exchange efficiency of the indoor air, thereby improving the uniformity of the indoor temperature and improving the user experience.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the indoor unit 1 of the air conditioner in this embodiment of the invention 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 and is used to open or close the first air inlet 13. The second air inlet cover 16 is rotatably disposed at the second air inlet 14 and is used to open or close the second air inlet 14. The air outlet cover 17 is rotatably disposed at the air outlet 12 and is used to open or close the air outlet 12.

[0050] Specifically, the air outlet 12 can be a rectangular opening with its length direction 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 with their length direction parallel to the horizontal direction of the front panel 11. Correspondingly, the air outlet cover 17, the first air inlet cover 15, and the second air inlet cover 16 can all be rectangular plates with their length direction parallel to the vertical direction of the front panel 11. Further, the number of the first air inlet cover 15, the second air inlet cover 16, and the air outlet cover 17 can all be one or more. In one specific embodiment, multiple first air inlet covers 15 are arranged along the horizontal direction of the front panel 11 at the first air inlet 13, multiple second air inlet covers 16 are arranged along the horizontal direction of the front panel 11 at the second air inlet 14, and multiple air outlet covers 17 are arranged along the horizontal direction of the front panel 11 at the air outlet 12.

[0051] When the indoor unit 1 of the air conditioner is started, the first air inlet cover 15, the second air inlet cover 16, and the air outlet cover 17 are all open to allow indoor airflow 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 indoor unit 1 of the air conditioner is not running, the first air inlet cover 15, the second air inlet cover 16, and the air outlet cover 17 are all closed to avoid the problems of unsightly appearance of the front panel 11 and poor safety due to the opening of the 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 appliances 2, so that they are consistent with the overall home style. This allows the first air inlet 13, the second air inlet 14, and the air outlet 12 of the air conditioner to be integrated into the overall home environment, further enhancing the overall aesthetics of the home environment and thus improving the user experience.

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

[0054] like Figure 3 As shown, the air duct component 100 is disposed inside the housing 10 near the air outlet 12, dividing the space inside the housing 10 into an air inlet chamber 110 communicating with the air inlet and an air outlet chamber 120 communicating with the air outlet 12. The air duct component 100 has multiple openings 130 to connect the air inlet chamber 110 and the air outlet chamber 120. The air outlet fan 200 is located inside the air outlet chamber 120, guiding the airflow in the air inlet chamber 110 into the air outlet chamber 120 and out through the air outlet 12.

[0055] In addition, such as Figure 3As shown, the indoor unit 1 of the air conditioner may also include a heat exchanger 30, which is disposed on the air duct 100 and located in the air inlet cavity 110, for exchanging heat with the airflow flowing into the air inlet cavity 110. That is, the heat exchanger 30 is located upstream of the air outlet fan 200, and the airflow after heat exchange by the heat exchanger 30 flows into the air outlet cavity 120 under the action of the air outlet fan 200, and is sent out through the air outlet 12 to regulate the indoor temperature.

[0056] In the indoor unit 1 of the air conditioner in this embodiment of the invention, the fan assembly 20 may further include a duct component 100 and an air outlet fan 200. The duct component 100 is disposed in the housing 10 near the air outlet 12 and is used to divide the space inside the housing 10 into an air inlet cavity 110 communicating with the air inlet and an air outlet cavity 120 communicating with 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 into the air outlet cavity 120 and out through the air outlet 12. The heat exchanger 30 of the indoor unit 1 is disposed on the duct component 100 and located in the air inlet cavity 110 and is used to exchange heat with the airflow flowing into the air inlet cavity 110. Therefore, the airflow entering the casing 10 from the first air inlet 13 and the second air inlet 14 can enter the air inlet cavity 110 and the air outlet cavity 120 in an orderly manner under the guidance of the air duct component 100, which improves the smoothness of airflow. In addition, the airflow can fully contact the heat exchanger 30 in the air inlet cavity 110, thereby improving the heat exchange efficiency of the airflow and further improving the heat exchange efficiency of the indoor air.

[0057] In some embodiments, such as Figure 3 As shown, the heat exchanger 30 is arranged around a portion of the outer periphery of the 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-closed annular structure. Therefore, the airflow in the inlet chamber 110 must pass over the surface of the heat exchanger 30 before flowing to the outlet fan 200, ensuring sufficient contact between the airflow in the inlet chamber 110 and the heat exchanger 30. This increases the contact area between the airflow in the inlet chamber 110 and the surface of the heat exchanger 30, thereby improving heat exchange efficiency and enhancing the cooling or heating effect.

[0058] Furthermore, the outlet fan 200 is a cross-flow fan, and its rotation axis is vertically oriented. Therefore, the outlet fan 200 can attract airflow located on its outer periphery, which flows in radially and is then blown out radially. For example... Figure 3As shown, the air inlet cavity 110 is arranged around the outer periphery of the air outlet cavity 120 at least on the left and right sides and at the rear. Under the action of the air outlet fan 200, the airflow flowing into the air inlet cavity 110 from the first air inlet 13 and the second air inlet 14 can flow into the air outlet cavity 120 in the radial direction of the air outlet fan 200, and be blown out of the air outlet cavity 120 in the radial direction of the air outlet fan 200.

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

[0060] In some embodiments, such as Figure 4 As shown, the upper and lower ends of the air duct component 100 are respectively spaced apart from the housing 10. Specifically, as... Figure 4 As shown, both the upper and lower ends of the air duct component 100 are hollow, forming air intake channels 140. Based on this, the spaces located on the upper and lower sides of the air duct component 100, as well as the spaces located on the left and right sides and the rear of the air duct component 100, are connected as a whole, forming part of the air intake cavity 110. That is to say, the air intake cavity 110 is arranged around the outer periphery of the air outlet cavity 120 on the upper and lower sides, left and right sides, and rear.

[0061] In addition, such as Figure 2 As shown, the indoor unit 1 of the air conditioner of the present invention may also have an installation component 700 installed inside the casing, which is located at the lower end of the air duct component 100 to support the lower end of the air duct component 100 and improve structural stability. The installation component 700 is at least partially hollow, so that the space of the air inlet cavity 110 located on the lower side of the air supply duct component 100 can be connected to the space of the air inlet cavity 110 located on the rear side of the air supply duct component 100 via the air inlet channel 140.

[0062] Therefore, the air conditioner indoor unit 1 of this embodiment has sufficient air intake space in the casing 10, thereby ensuring air intake efficiency. Furthermore, the surrounding air intake method improves the heat exchange efficiency between the airflow in the air intake cavity 110 and the heat exchanger 30, thereby further improving the heat exchange efficiency of the air conditioner indoor unit 1 and thus improving the user experience.

[0063] In some embodiments, such 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 intake fan 300 is located inside the housing 10 near the first air inlet 13, and is used to guide indoor airflow from the first air inlet 13 into the housing 10. The second air intake fan 400 is located inside the housing 10 near the second air inlet 14, and is used to guide indoor airflow from the second air inlet 14 into the housing 10.

[0065] In the indoor unit 1 of the air conditioner in this embodiment of the invention, the fan assembly 20 may include a first intake fan 300 and a second intake fan 400. The first intake fan 300 is disposed inside the housing 10 near the first air inlet 13 and is used to guide indoor airflow from the first air inlet 13 into the housing 10. The second intake fan 400 is disposed inside the housing 10 near the second air inlet 14 and is used to guide indoor airflow from the second air inlet 14 into the housing 10. Thus, intake fans are provided at both the first air inlet 13 and the second air inlet 14, which 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 indoor unit 1 and further improving the heat exchange efficiency of the indoor air.

[0066] In some embodiments, such 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 dimensions of the front panel 11 in the left-right direction. That is to say, the dimension L of the first air inlet 13 in the left-right direction 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 neatness of the appearance of the first air inlet 13 and the second air inlet 14 on the front panel 11.

[0067] Furthermore, the dimensions L of the first air inlet 13 in the left-right direction 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 dimension d of the front panel 11 in the left-right direction. Specifically, the dimensions L of the first air inlet 13 in the left-right direction and 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 one specific embodiment, the dimensions L of the first air inlet 13 in the left-right direction and 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 intake area of ​​the air conditioner indoor unit 1, and further improving the overall air intake efficiency of the air conditioner indoor unit 1, so as to improve the heat exchange efficiency of indoor air.

[0069] In addition, such as 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] Therefore, the first air inlet 13 located above the air outlet 12 can have a sufficiently large area, effectively ensuring air intake efficiency even when air intake below is obstructed due to ground obstacles. At the same time, more airflow from the upper space of the room can enter the casing 10 for heat exchange, further improving the heat exchange efficiency of the indoor air, thereby improving the uniformity of indoor temperature and thus enhancing the user experience.

[0071] In some embodiments, such as Figure 2 As shown, the indoor unit 1 of the air conditioner may also include multiple swing blades 40 and a drive mechanism (not shown in the figure). The multiple swing blades 40 are rotatably disposed within the air outlet cavity 120 near the air outlet 12. Figure 2 As shown, multiple swivel blades 40 are evenly spaced along the vertical direction. A drive mechanism is used to drive the swivel blades 40 to rotate, thereby adjusting the air outlet direction of the air outlet 12. As a result, the indoor unit 1 of the air conditioner can outlet air in multiple directions, effectively increasing the air outlet range, thus giving the indoor unit 1 a wide air supply range.

[0072] In one specific embodiment, the rotation axis of the oscillating blade 40 can be set vertically. Therefore, the air outlet 12 can be adjusted left and right, allowing the indoor unit 1 to outlet air forward, left, or right.

[0073] In another specific embodiment, the rotation axis of the oscillating blade 40 can also be set horizontally. Therefore, the air outlet 12 can be adjusted vertically, allowing the indoor unit 1 to outlet air forward, upward, or downward.

[0074] In the air conditioner indoor unit 1 of this embodiment, the air conditioner indoor unit 1 may also include a plurality of swing blades 40 and a drive mechanism. The plurality of swing blades 40 are rotatably and spaced apart in the air outlet cavity 120 at positions adjacent to the air outlet 12. The drive mechanism is used to drive the swing blades 40 to rotate in order to adjust the air outlet 12 air outlet direction, thereby realizing more diversified air supply methods and further improving the user experience.
