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 outlets. Background Technology

[0002] As people's living standards continue to improve, built-in air conditioners are gradually becoming a better choice for users because they can be perfectly integrated into the home environment. Existing built-in air conditioners are usually cabinet-mounted air conditioners, which means that only the front of the unit is exposed, thus determining its air intake and exhaust pattern to be front-to-front-out.

[0003] However, currently available built-in air conditioners typically only have one air inlet on the lower front side of the indoor unit and one air outlet on the upper front side. Furthermore, the evaporator is only located between the inlet and outlet, below the outlet, resulting in low heat exchange efficiency. Additionally, the evaporator's angled placement between the inlet and outlet leads to low space utilization within the indoor unit, severely limiting fan size due to space constraints, and consequently, low intake and exhaust efficiency, further contributing to the low heat exchange efficiency of built-in air conditioners. 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 object of the present invention is to provide an air conditioning indoor unit that can improve heat exchange efficiency, thereby improving the user experience.

[0006] A further objective of this invention is to optimize the internal structure of the air conditioner indoor unit, thereby further improving the heat exchange efficiency of the air conditioner indoor unit.

[0007] Another further objective of this invention is to improve the space utilization rate inside the indoor unit of an air conditioner.

[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 inlet and a first air outlet and a second air outlet are located on the upper and lower sides of the air inlet, respectively.

[0010] An air duct assembly is disposed inside the housing and defines an air inlet duct, a first air outlet duct, and a second air outlet duct. The air inlet duct is connected to the air inlet, the first air outlet duct is connected to the first air outlet, and the second air outlet duct is connected to the second air outlet.

[0011] A first outlet fan, installed within a first outlet duct, is used to guide airflow within the first outlet duct out through the first outlet; and

[0012] The second air outlet fan is installed inside the second air outlet duct and is used to guide the airflow in the second air outlet duct to be sent out from the second air outlet.

[0013] Furthermore, a heat exchanger is installed inside the casing near the air inlet to exchange heat with the airflow flowing into the air inlet duct.

[0014] Furthermore, the projection of the heat exchanger in the front view direction of the indoor unit of the air conditioner covers the projection of the air inlet in the front view direction of the indoor unit of the air conditioner.

[0015] Furthermore, the projection of the heat exchanger in the front view direction of the indoor unit of the air conditioner coincides with the projection of the air inlet in the front view direction of the indoor unit of the air conditioner.

[0016] Furthermore, the first air outlet duct and the second air outlet duct are arranged at intervals in the vertical direction, and the first air outlet duct is located above the second air outlet duct.

[0017] Furthermore, both the first and second exhaust fans are located within the air duct assembly near the air inlet.

[0018] Furthermore, the outlet fan is a centrifugal fan, and the rotation axis of the outlet fan is set horizontally.

[0019] Furthermore, the left and right ends of the outlet fan are spaced apart from the left and right outer walls of the inlet duct so that the airflow in the inlet duct enters the outlet fan from the left and right sides.

[0020] Furthermore, the projected area of ​​the air inlet in the direction of view of the indoor unit is 0.7 to 0.9 times the projected area of ​​the front panel in the direction of view of the indoor unit; and / or

[0021] The sum of the projected areas of the first and second air outlets in the direction of view of the indoor unit is 0.05 to 0.25 times the projected area of ​​the front panel in the direction of view of the indoor unit.

[0022] Furthermore, the indoor unit of the air conditioner also includes:

[0023] An air inlet cover is rotatably mounted at the air inlet for opening or closing the air inlet;

[0024] A first air outlet cover is rotatably mounted at a first air outlet for opening or closing the first air outlet; and

[0025] The second air outlet cover is rotatably mounted at the second air outlet and is used to open or close the second air outlet.

[0026] Furthermore, the indoor unit of the air conditioner is placed inside the cavity that houses the household appliance.

[0027] The indoor unit of this invention has an air inlet and a first air outlet and a second air outlet located on the upper and lower sides of the air inlet on the front panel of its casing. An air duct assembly and the casing define an air inlet duct, a first air outlet duct, and a second air outlet duct. The air inlet duct communicates with the air inlet, the first air outlet duct communicates with the first air outlet, and the second air outlet duct communicates with the second air outlet. The indoor unit also includes a first air outlet fan located in the first air outlet duct and a second air outlet fan located in the second air outlet duct. The first air outlet fan guides the airflow within the first air outlet duct to exit through the first air outlet, and the second air outlet fan guides the airflow within the second air outlet duct to exit through the second air outlet, thus forming a central air inlet and vertical air outlet configuration where air can exit from both the upper and lower sides of the central air inlet. This vertical air outlet configuration of the indoor unit effectively avoids the problem of poor airflow that easily occurs in single-sided air outlet configurations. Meanwhile, the indoor air conditioner unit of the present invention can output air from both the upper and lower sides of the air inlet, avoiding the problem of insufficient heat exchange of air on the upper or lower side of the room caused by setting a single air outlet on one side of the upper or lower side of the air inlet. This improves the air output efficiency, thereby improving the heat exchange efficiency of the indoor air and thus improving the uniformity of the indoor temperature, thereby improving the user experience.

[0028] Furthermore, in the indoor unit of the air conditioner of the present invention, the heat exchanger is disposed inside the casing near the air inlet, for exchanging heat with the airflow flowing into the air inlet duct. Thus, the indoor unit of the air conditioner of the present invention optimizes the internal structure, ensuring that the airflow entering the air inlet duct from the air inlet can directly exchange heat with the heat exchanger, greatly improving the heat exchange efficiency of the incoming airflow, thereby improving the overall heat exchange efficiency of the indoor unit and further enhancing the user experience.

[0029] Furthermore, in the indoor unit of the air conditioner of the present invention, the first air outlet duct and the second air outlet duct are arranged vertically at intervals, with the first air outlet duct located above the second air outlet duct. Thus, the first and second air outlet ducts can be neatly arranged inside the indoor unit, thereby improving the space utilization rate inside the indoor unit. Simultaneously, the airflow entering the air inlet duct from the air inlet can flow upwards under the action of the first air outlet fan and be blown out from the first air outlet; the airflow entering the air inlet duct from the air inlet can also flow downwards under the action of the second air outlet fan and be blown out from the second air outlet. This achieves orderly flow of airflow entering the casing from the air inlet under the guidance of the duct components, improving the smoothness of the airflow within the casing and further enhancing the overall heat exchange efficiency of the indoor unit.

[0030] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0035] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. 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.

[0036] Figure 1 This 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 side view schematic diagram of the indoor unit 1 of an air conditioner according to an embodiment of the present invention.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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, an air duct assembly 20, a first air outlet fan 30, and a second air outlet fan 40.

[0041] like Figure 1 and Figure 2 As shown, the casing 10 includes a front panel 11, on which an air inlet 12 and a first air outlet 13 and a second air outlet 14 are respectively located on the upper and lower sides of the air inlet 12. The first air outlet 13 and the second air outlet 14 are 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.

[0042] The air duct assembly 20 is disposed within the housing 10 and defines an inlet air duct 100, a first outlet air duct 200, and a second outlet air duct 300. The inlet air duct 100 communicates with the air inlet 12, the first outlet air duct 200 communicates with the first outlet 13, and the second outlet air duct 300 communicates with the second outlet 14. Furthermore, the air duct assembly 20 is provided with multiple openings to allow communication between the inlet air duct 100 and the outlet air duct.

[0043] like Figure 2 As shown, the first outlet fan 30 is disposed within the first outlet duct 200 and is used to guide the airflow within the first outlet duct 200 out through the first outlet 13. The second outlet fan 40 is disposed within the second outlet duct 300 and is used to guide the airflow within the second outlet duct 300 out through the second outlet 14. The first outlet fan 30 and the second outlet fan 40 are also used to guide the airflow within the inlet duct 100 into the first outlet duct 200 and the second outlet duct 300, respectively.

[0044] The indoor unit 1 of the air conditioner in this embodiment of the invention has an air inlet 12 and a first air outlet 13 and a second air outlet 14 located on the upper and lower sides of the air inlet 12, respectively. The air duct assembly 20 and the housing 10 define an air inlet duct 100, a first air outlet duct 200, and a second air outlet duct 300. The air inlet duct 100 communicates with the air inlet 12, the first air outlet duct 200 communicates with the first air outlet 13, and the second air outlet duct 300 communicates with the second air outlet 14. Furthermore, the indoor unit 1 of the air conditioner is equipped with a first air outlet fan 30 located in the first air outlet duct 200 and a second air outlet fan 40 located in the second air outlet duct 300. The first air outlet fan 30 is used to guide the airflow in the first air outlet duct 200 to be sent out from the first air outlet 13, and the second air outlet fan 40 is used to guide the airflow in the second air outlet duct 300 to be sent out from the second air outlet 14, forming a central air intake and vertical air outlet configuration where air can be discharged from both the upper and lower sides of the central air intake 12. The vertical air outlet configuration of the indoor unit 1 of the air conditioner in this embodiment of the invention effectively avoids the problem of poor airflow that is prone to occur in the single-sided air outlet configuration.

[0045] Meanwhile, the indoor air conditioner 1 of this embodiment can achieve air outlets on both the upper and lower sides of the air inlet 12, avoiding the problem of insufficient heat exchange of air on the upper or lower side of the room due to setting a single air outlet on one side of the upper or lower side of the air inlet 12. This improves the air outlet efficiency, thereby improving the heat exchange efficiency of the indoor air and thus improving the uniformity of the indoor temperature, thereby improving the user experience.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the indoor unit 1 of the air conditioner may also include an air inlet cover 15, a first air outlet cover 16, and a second air outlet cover 17.

[0047] An air inlet cover 15 is rotatably disposed at the air inlet 12 for opening or closing the air inlet 12. A first air outlet cover 16 is rotatably disposed at the first air outlet 13 for opening or closing the first air outlet 13. A second air outlet cover 17 is rotatably disposed at the second air outlet 14 for opening or closing the second air outlet 14.

[0048] Specifically, the air inlet 12 can be a rectangular opening with its length direction parallel to the vertical direction of the front panel 11, and the first air outlet 13 and the second air outlet 14 can both be rectangular openings with their length direction parallel to the horizontal direction of the front panel 11. Correspondingly, the air inlet cover 15, the first air outlet cover 16 and the second air outlet cover 17 can both be rectangular plates with their length direction parallel to the vertical direction of the front panel 11.

[0049] Furthermore, the number of air inlet cover 15, first air outlet cover 16, and second air outlet cover 17 can each be one or more. In one specific embodiment, multiple air inlet covers 15 are arranged along the left-right direction of the front panel 11 at the air inlet 12, multiple first air outlet covers 16 are arranged along the left-right direction of the front panel 11 at the first air outlet 13, and multiple second air outlet covers 17 are arranged along the left-right direction of the front panel 11 at the second air outlet 14.

[0050] When the indoor unit 1 of the air conditioner is started, the air inlet cover 15, the first air outlet cover 16, and the second air outlet cover 17 are all open to allow indoor airflow to flow into the casing 10 from the air inlet 12 and be discharged through the first air outlet 13 and the second air outlet 14. When the indoor unit 1 of the air conditioner is stopped, the air inlet cover 15, the first air outlet cover 16, and the second 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 open air inlet 12, the first air outlet 13, and the second air outlet 14, thereby improving the user experience.

[0051] In addition, the air inlet cover 15, the first air outlet cover 16 and the second 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, and the air inlet 12, the first air outlet 13 and the second air outlet 14 of the air conditioner can be integrated into the overall home environment, further enhancing the overall aesthetics of the home environment, thereby improving the user experience.

[0052] In some embodiments, such as Figure 2 and Figure 3 As shown, the first air outlet duct 200 and the second air outlet duct 300 are arranged at intervals in the vertical direction, and the first air outlet duct 200 is located above the second air outlet duct 300. Thus, the first air outlet duct and the second air outlet duct 300 can be neatly arranged inside the air conditioner indoor unit 1, thereby improving the space utilization rate inside the air conditioner indoor unit 1.

[0053] In the indoor unit 1 of the air conditioner in this embodiment of the invention, the airflow entering the air intake duct 100 from the air inlet 12 can flow upward under the action of the first air outlet fan 30 and be blown out from the first air outlet 13. The airflow entering the air intake duct 100 from the air inlet 12 can also flow downward under the action of the second air outlet fan 40 and be blown out from the second air outlet 14. This realizes that the airflow entering the casing 10 from the air inlet 12 can flow in an orderly manner under the guidance of the duct components, which improves the smoothness of the airflow in the casing 10 and the airflow in the outlet, thereby further improving the overall heat exchange efficiency of the indoor unit 1.

[0054] In some embodiments, such as Figure 2 and Figure 3As shown, the first outlet fan 30 and the second outlet fan 40 are both located within the air duct assembly 20 near the air inlet 12. Therefore, the airflow at the air inlet 12 can quickly enter the air intake duct 100 under the combined action of the first outlet fan 30 and the second outlet fan 40, greatly improving the air intake efficiency of the air inlet 12, thereby improving the overall air intake efficiency of the indoor unit 1, and further improving the heat exchange efficiency of the indoor air.

[0055] In some embodiments, such as Figure 3 As shown, the outlet fans are centrifugal fans, and their rotation axes are horizontally positioned. That is, both the first outlet fan 30 and the second outlet fan 40 are centrifugal fans, and their rotation axes are both horizontally positioned. Since centrifugal fans have axial air intake and radial air exhaust, the first outlet fan 30 and the second outlet fan 40 can guide the airflow within the inlet duct 100 to enter from the left and right sides of the first outlet fan 30 and the second outlet fan 40, respectively, and then radially eject the airflow to enter the first outlet duct 200 and the second outlet duct 300, respectively.

[0056] In the indoor unit 1 of the air conditioner in this embodiment of the invention, the air outlet fan can be set as a centrifugal fan, which reduces the space occupied while ensuring the largest possible air pressure, thereby effectively overcoming the wind resistance caused by the narrow air duct, improving the air outlet efficiency, and thus improving the overall heat exchange efficiency of the indoor unit 1.

[0057] Because the centrifugal fan has axial air intake and radial air outlet, and the rotation axes of the first outlet fan 30 and the second outlet fan 40 are both horizontally positioned, the first outlet fan 30 and the second outlet fan 40 need to intake air from both the left and right sides. To ensure smooth air intake, in some embodiments, such as... Figure 2 As shown, the left and right ends of the first air outlet fan 30 and the second air outlet fan 40 are spaced apart from the left and right outer walls 110 of the air inlet duct 100, so that the airflow in the air inlet duct 100 can enter the first air outlet fan 30 and the second air outlet fan 40 from the left and right sides respectively.

[0058] Therefore, the first outlet fan 30 can guide the airflow in the inlet duct 100 to enter from the left and right sides of the first outlet fan 30, and throw it out radially from the first outlet fan 30 to enter the first outlet duct 200. The second outlet fan 40 can guide the airflow in the inlet duct 100 to enter from the left and right sides of the second outlet fan 40, and throw it out radially from the second outlet fan 40 to enter the second outlet duct 300.

[0059] In this embodiment of the invention, the indoor unit 1 of the air conditioner is designed such that the left and right ends of the first air outlet fan 30 and the second air outlet fan 40 are spaced apart from the left and right outer walls 110 of the air inlet duct 100. This ensures that the air inlet duct 100 is arranged around the left and right sides of the first air outlet fan 30 and the second air outlet fan 40, thus guaranteeing sufficient air intake space on both sides of the first air outlet fan 30 and the second air outlet fan 40 in the axial direction. This ensures air intake efficiency and further improves the heat exchange efficiency of the indoor unit 1, thereby enhancing the user experience.

[0060] In some embodiments, the projected area of ​​the air inlet 12 in the frontal viewing direction of the indoor unit 1 is 0.7 to 0.9 times the projected area of ​​the front panel 11 in the frontal viewing direction of the indoor unit 1. Specifically, the projected area of ​​the air inlet 12 in the frontal viewing direction of the indoor unit 1 is 0.8 to 0.9 times the projected area of ​​the front panel 11 in the frontal viewing direction of the indoor unit 1. In one specific embodiment, the projected area of ​​the air inlet 12 in the frontal viewing direction of the indoor unit 1 is 0.85 times the projected area of ​​the front panel 11 in the frontal viewing direction of the indoor unit 1.

[0061] Therefore, the air inlet 12 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.

[0062] The sum of the projected areas of the first air outlet 13 and the second air outlet 14 in the frontal viewing direction of the indoor unit 1 is 0.05 to 0.25 times the projected area of ​​the front panel 11 in the frontal viewing direction of the indoor unit 1. Specifically, the sum of the projected areas of the first air outlet 13 and the second air outlet 14 in the frontal viewing direction of the indoor unit 1 is 0.07 to 0.13 times the projected area of ​​the front panel 11 in the frontal viewing direction of the indoor unit 1. In one specific embodiment, the sum of the projected areas of the first air outlet 13 and the second air outlet 14 in the frontal viewing direction of the indoor unit 1 is 0.1 times the projected area of ​​the front panel 11 in the frontal viewing direction of the indoor unit 1.

[0063] Therefore, when the air conditioner indoor unit 1 of this embodiment delivers air from the first air outlet 13 and the second air outlet 14, it can deliver air with a sufficiently large air pressure, thereby improving the air delivery capacity of the air conditioner indoor unit 1 and further improving the uniformity of indoor temperature.

[0064] In some embodiments, such as Figure 2 and Figure 3As shown, the indoor unit 1 of the air conditioner may also include a heat exchanger 50. Specifically, the heat exchanger 50 is disposed inside the casing 10 near the air inlet 12 and is used to exchange heat with the airflow flowing into the air inlet duct 100.

[0065] Therefore, the air conditioner indoor unit 1 of this embodiment optimizes the internal structure, ensuring that the airflow entering the air intake duct 100 from the air inlet 12 can directly exchange heat with the heat exchanger 50, which greatly improves the heat exchange efficiency of the air intake airflow, thereby improving the overall heat exchange efficiency of the air conditioner indoor unit 1, and further improving the user experience.

[0066] In some embodiments, such as Figure 3 As shown, the projection of the heat exchanger 50 in the front view direction of the indoor unit 1 covers the projection of the air inlet 12 in the front view direction of the indoor unit 1. That is to say, the projected area of ​​the heat exchanger 50 in the front view direction of the indoor unit 1 is at least not less than the projected area of ​​the air inlet 12 in the front view direction of the indoor unit 1, and the heat exchanger 50 can completely cover the air inlet 12.

[0067] Therefore, the airflow at the air inlet 12 must pass through the surface of the heat exchanger 50 before entering the air inlet duct 100, thus ensuring sufficient contact between the airflow and the heat exchanger 50. This increases the contact area between the airflow in the air inlet duct 100 and the surface of the heat exchanger 50, thereby improving the heat exchange efficiency, enhancing the cooling or heating effect, and further improving the user experience.

[0068] In one specific embodiment, the projection of the heat exchanger 50 onto the front view of the indoor unit 1 coincides with the projection of the air inlet 12 onto the front view of the indoor unit 1. That is, the projected area of ​​the heat exchanger 50 onto the front view of the indoor unit 1 is equal to the projected area of ​​the air inlet 12 onto the front view of the indoor unit 1.

[0069] Therefore, while ensuring that the incoming airflow is in full contact with the heat exchanger 50, the space occupied by the heat exchanger 50 is reduced, thereby improving the space utilization rate of the indoor unit 1 of the air conditioner.

[0070] Specifically, such as Figure 2 As shown, the heat exchanger 50 can be a rectangular plate structure, and the heat exchanger 50 can be fitted to the air inlet 12, thereby further improving the degree of contact between the airflow and the heat exchanger 50, and further improving the heat exchange efficiency to improve the cooling or heating effect.

[0071] In some embodiments, the indoor air conditioning unit 1 may further include multiple swivel blades and a drive mechanism. The multiple swivel blades are rotatably disposed at the first air outlet 13 and the second air outlet 14. Specifically, the multiple swivel blades at each air outlet may be evenly spaced in the left-right direction. The drive mechanism is used to drive the swivel blades to rotate, thereby adjusting the air outlet direction of the first air outlet 13 and the second air outlet 14. Thus, the indoor air conditioning unit 1 can outlet air in multiple directions, effectively increasing the air outlet range, thereby giving the indoor air conditioning unit 1 a wide air supply range.

[0072] In one specific embodiment, the rotation axis of the oscillating blades can be set vertically. As a result, the air outlet direction of the first air outlet 13 and the second air outlet 14 can be adjusted left and right, so that the indoor unit 1 of the air conditioner can outlet air forward, left, and right.

[0073] In the air conditioner indoor unit 1 of this embodiment, the air conditioner indoor unit 1 may also include multiple swing blades and a drive mechanism. The multiple swing blades are rotatably arranged at intervals at the first air outlet 13 and the second air outlet 14. The drive mechanism is used to drive the swing blades to rotate in order to adjust the air outlet direction, thereby realizing more diversified air supply methods and further improving the user experience.
