Description

Technical Field

[0001] This application relates to the field of air handling technology, and more particularly to an indoor air conditioning unit. Background Technology

[0002] Most existing air conditioner indoor units have only one air inlet and one air outlet, with a fixed duct structure. However, the air density differs between cooling and heating modes. When cooling, the air density from the outlet is typically greater than the indoor air density, causing the air to sink; when heating, the air density is typically less than the indoor air density, causing the air to rise. Since both cooling and heating operate from the same outlet, this inevitably leads to uneven airflow coverage throughout the room under either cooling or heating conditions, resulting in poorer comfort for occupants. Summary of the Invention

[0003] This application provides an indoor air conditioning unit that can meet the needs of different air outlet directions for cooling / heating, thereby significantly improving room temperature comfort.

[0004] In one aspect of this application, an indoor unit for an air conditioner includes: a casing, a heat exchanger, and a fan. The casing includes an air outlet panel, a first portion of which forms a side wall of the casing, and a second portion of which forms a portion of the bottom wall of the casing. The heat exchanger is disposed inside the casing. The fan is used to blow air that has undergone heat exchange through the heat exchanger onto the air outlet panel. The air outlet panel is arc-shaped, and multiple air outlets are arranged along the circumference of the air outlet panel. The air outlet on the first part of the air outlet panel is the first air outlet, and the air outlet on the second part of the air outlet panel is the second air outlet. The indoor unit of the air conditioner also includes: a rotating guide plate, which is rotatably connected to the casing; the rotating guide plate includes a plurality of baffles arranged at intervals along the circumferential direction, the plurality of baffles including a first baffle and a second baffle; The rotating guide plate can rotate between a first position and a second position. In the first position, the first baffle is offset from the first air outlet, and the second baffle blocks the second air outlet, so that air is blown out from the first air outlet. In the second position, the first baffle blocks the first air outlet, and the second baffle is offset from the second air outlet, so that air is blown out from the second air outlet.

[0005] In this technical solution, by setting the air outlet panel to an arc shape and setting a rotating guide plate on the inner side of the air outlet panel, the rotating guide plate can be rotated to a first position where the first air outlet is opened and the second air outlet is closed, and to a second position where the second air outlet is opened and the first air outlet is closed, thereby realizing air supply from different directions and improving room temperature comfort.

[0006] When cooling, you can choose to send air into the room from the first air outlet to avoid the problem of cold air blowing directly on people and causing poor comfort. It also helps the cold air to cover the entire room from top to bottom. When heating, you can choose to send air into the room from the second air outlet to help the hot air sink and avoid the problem of the hot air not being able to blow down, which would result in poor heating effect.

[0007] In some embodiments, the space between the baffles is a communication port, which includes a first communication port and a second communication port; in the first position, the first communication port is connected to the first air outlet; in the second position, the second communication port is connected to the second air outlet.

[0008] In this technical solution, a connecting port is provided between the baffles, which connects to the first air outlet or the second air outlet to enable the opening of the first or second air outlet.

[0009] In some embodiments, the two ends of the circumferential direction of the plurality of baffles are respectively the first end and the second end, with the first end located above the second end; starting from the first end, the first baffles and the first connecting ports are arranged alternately, and the number of the first baffles and the number of the first connecting ports are the same as the number of the first air outlets; starting from the second end, the second baffles and the second connecting ports are arranged alternately, and the number of the second baffles and the number of the second connecting ports are the same as the number of the second air outlets.

[0010] In this technical solution, by arranging the first baffle and the second baffle, the rotating guide plate can selectively open the first air outlet or the second air outlet.

[0011] In some embodiments, the rotation center line of the rotating guide plate coincides with the center line of the air outlet panel; when projected onto a plane perpendicular to the rotation center line of the rotating guide plate, the central angle corresponding to the air outlet is α, and the central angle corresponding to the baffle is γ, where γ > α.

[0012] In this technical solution, by setting γ > α, the arc length of the baffle is greater than that of the air outlet, so that the baffle can effectively block the air outlet.

[0013] In some embodiments, the central angle corresponding to the overall outline of the plurality of air outlets is A, and the central angle corresponding to the overall outline of the plurality of baffles is B, where B = A + γ, when projected onto a plane perpendicular to the rotation center line of the rotating guide plate.

[0014] In this technical solution, B=A+γ, ensuring the function of the rotating guide plate in opening and closing the air outlet, while minimizing the area covered by the baffle in the circumferential direction, thus reducing the space occupied by the baffle.

[0015] In some embodiments, the rotating guide plate further includes a support plate connected to both ends of the baffle along its length, and the support plate is rotatably connected to the housing.

[0016] In this technical solution, support plates are set at both ends of the baffle, and the rotational connection between the rotating guide plate and the machine casing is realized by the support plates.

[0017] In some embodiments, the support plate includes: a support plate body; and a connecting part connected to the support plate body, the connecting part being an arc shape with the rotation center of the rotating guide plate as the center, and the connecting part being provided with a rotating shaft.

[0018] In some embodiments, the indoor unit of the air conditioner further includes a motor, which is fixedly connected to the side plate of the casing, and the output shaft of the motor is connected to the rotating shaft through a gear transmission mechanism.

[0019] In this technical solution, the motor transmits the rotational driving force to the rotating shaft through a gear transmission mechanism to realize the rotation of the rotating guide plate.

[0020] In some embodiments, the housing further includes: a base plate connected to the bottom of the air outlet panel; the air outlet panel is located on the upper side of the plane containing the bottom surface of the base plate.

[0021] In this technical solution, by limiting the positions of the air outlet panel and the base plate, the base plate can contact the ceiling or other tabletops in some scenarios, ensuring the stable placement of the air conditioner indoor unit on the tabletop.

[0022] In another aspect of this application, an indoor air conditioning unit includes: a housing, a heat exchanger, and a fan. The housing includes an air outlet panel, a first portion of which forms a side wall of the housing, and a second portion of which forms a portion of the bottom wall of the housing. The heat exchanger is disposed inside the housing. The fan is used to blow air that has undergone heat exchange through the heat exchanger onto the air outlet panel. The first part of the air outlet panel is provided with multiple first air outlets, and the second part of the air outlet panel is provided with multiple second air outlets; The indoor unit of the air conditioner also includes: an air outlet guide, connected to the inner side of the air outlet panel, the inner side of the air outlet guide being an arc surface, the air outlet guide having a first air outlet path communicating with a first air outlet and a second air outlet path communicating with a second air outlet; and a rotating guide plate, rotatably connected to the housing, the rotating guide plate including multiple baffles spaced apart along the circumferential direction, the multiple baffles including a first baffle and a second baffle. The rotating guide plate can rotate between a first position and a second position. In the first position, the first baffle is offset from the first air outlet path, and the second baffle blocks the second air outlet path, so that air passes through the first air outlet path and is blown out from the first air outlet. In the second position, the first baffle blocks the first air outlet path, and the second baffle is offset from the second air outlet path, so that air passes through the second air outlet path and is blown out from the second air outlet.

[0023] In this technical solution, by setting an air outlet guide and setting an air outlet path on the air outlet guide that is connected to the air outlet, rotating the guide plate closes the air outlet by closing the air outlet path and opens the air outlet by opening the air outlet path, thereby achieving air delivery from different directions.

Detailed Implementation

[0026] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0027] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0031] The compressor compresses refrigerant gas at a low temperature and low pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0032] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0033] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0034] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0035] This application relates to an indoor unit for air conditioning an indoor space. In the following text, for convenience, the indoor unit including an indoor heat exchanger is referred to as an air conditioning indoor unit, and the indoor heat exchanger is referred to as a heat exchanger.

[0036] Reference Figures 1 to 3 An air conditioner indoor unit according to an embodiment of this application includes a housing 10. The housing 10 forms the overall appearance of the air conditioner indoor unit.

[0037] The housing 10 may include an air outlet panel 14. A first portion of the air outlet panel 14 forms a side wall of the housing 10, and a second portion of the air outlet panel 14 forms a portion of the bottom wall of the housing 10.

[0038] The air outlet panel 14 is provided with multiple air outlets 141. The air outlet 141 located on the first part of the air outlet panel 14 is the first air outlet 141a, and the air outlet 141 located on the second part of the air outlet panel 14 is the second air outlet 141b.

[0039] For ease of description, in this application, the first part of the air outlet panel 14 is defined as being located on the front side of the housing 10, and the other side of the housing 10 opposite to the front side is defined as the rear side.

[0040] Reference Figure 2 The arrows in the diagram indicate the airflow direction. When the indoor unit of the air conditioner delivers air through the first air outlet 141a, the air is generally blown into the room from the first air outlet 141a towards the front of the casing 10. (Refer to...) Figure 3 The diagram illustrates the airflow direction. When the indoor unit of the air conditioner delivers air through the second air outlet 141b, the air is generally blown into the room from the second air outlet 141b towards the lower side of the casing 10.

[0041] When cooling, air can be directed into the room from the first air outlet 141a, avoiding direct cold air blowing on people and causing poor comfort. It also facilitates the cooling air covering the entire room from top to bottom. When heating, air can be directed into the room from the second air outlet 141b, which helps hot air sink and avoids poor heating effect caused by hot air not being able to fall. By setting the first air outlet 141a and the second air outlet 141b, this application significantly improves the temperature comfort of the indoor space, with cooling air blown out from the first air outlet 141a and heating air blown out from the second air outlet 141b.

[0042] An air inlet 131 may be provided on the rear side of the housing 10. Air from the indoor space enters the housing 10 through the air inlet 131. In other embodiments, the air inlet 131 may also be provided on the bottom rear side of the housing 10, and the second air outlet 141b is located on the bottom front side of the housing 10.

[0043] The indoor unit of the air conditioner may include a heat exchanger 20. The heat exchanger 20 is disposed inside the casing 10 and may be positioned along the airflow path from the air inlet 131 to the air outlet 141. The heat exchanger 20 is used to absorb heat from the air introduced into the air inlet 131 or to transfer heat to the air. A drip tray 21 may be disposed below the heat exchanger 20 to collect condensed moisture within the heat exchanger 20. The drip tray 21 may be connected to a drain hose that connects to the outside of the casing 10, and may discharge condensed moisture to the outside of the casing 10.

[0044] The indoor unit of the air conditioner may include a fan assembly 30. The fan assembly 30 is disposed inside the housing 10, allowing air to flow from the air inlet 131 to the air outlet 141. The fan assembly 30 may be a centrifugal fan.

[0045] The fan assembly includes an impeller 31. When the impeller 31 rotates, it drives the airflow. The impeller 31 includes a central disk 311 and a plurality of blades 312 connected to the central disk 311 circumferentially.

[0046] The fan assembly includes a volute 32, which covers the impeller 31. Inlet ports are located on opposite side walls of the volute 32, through which air enters the volute 32. The two inlet ports are arranged along the axis of the impeller 31. An outlet port 321 is located on the volute 32, through which the fan assembly 30 discharges air.

[0047] In some embodiments, the fan assembly 30 may be located on the air inlet side of the heat exchanger 20, that is, the fan assembly 30 is located near the air inlet 131 and the heat exchanger 20 is located near the air outlet 141.

[0048] The housing 10 is provided with a partition 16, which divides the space inside the housing 10 into an air outlet chamber 10b and an air inlet chamber 10a distributed front and rear. The air inlet 131 is connected to the air inlet chamber 10a, and the fan assembly 30 is disposed in the air inlet chamber 10a; the heat exchanger 20 is disposed in the air outlet chamber 10b, and the air outlet 141 is connected to the air outlet chamber 10b.

[0049] The outlet 321 of the volute 32 passes through the partition plate 16 so that the outlet 321 of the volute 32 is connected to the air outlet cavity 10b.

[0050] When the impeller 31 rotates, the air in the indoor space enters the air inlet chamber 10a from the air inlet 131, and then flows through the inlet and outlet 321 of the volute 32 to the heat exchanger 20 of the air outlet chamber 10b. After exchanging heat with the heat exchanger 20, the air returns to the indoor space through the air outlet 141.

[0051] In some embodiments, refer to Figures 1 to 4 The air outlet panel 14 is arc-shaped. Multiple air outlets 141 are arranged at intervals along the circumference. The multiple air outlets 141 can be evenly distributed along the circumference.

[0052] The housing 10 may include a top plate 11 forming the top structure of the housing 10; a bottom plate 12 connected to the bottom rear side of the air outlet panel 14; a rear side plate 13 connected between the rear end of the top plate 11 and the rear end of the bottom plate 12; a left side plate connected between the left end of the top plate 11 and the left end of the bottom plate 12; and a right side plate connected between the right end of the top plate 11 and the right end of the bottom plate 12.

[0053] The upper end of the air outlet panel 14 in the circumferential direction is connected to the front end of the top plate 11, and the bottom of the air outlet panel 14 is connected to the front end of the bottom plate 12.

[0054] In some embodiments, refer to Figures 2 to 4 The indoor unit of the air conditioner may include a rotating guide plate 40. The rotating guide plate 40 is rotatably connected to the inside of the air outlet panel 14.

[0055] The rotating guide plate 40 can rotate between a first position and a second position. In the first position, as follows: Figure 2 As shown, rotating the guide plate 40 opens the first air outlet 141a and closes the second air outlet 141b; in the second position, as... Figure 3 As shown, rotating the guide plate 40 opens the second air outlet 141b and closes the first air outlet 141a. The rotation of the guide plate 40 allows for the selective closure of either the first air outlet 141a or the second air outlet 141b.

[0056] In this application, by setting the air outlet panel 14 in an arc shape and providing a rotating guide plate 40 on the inner side of the air outlet panel 14, the rotating guide plate 40 can be rotated to a first position where the first air outlet 141a is opened and the second air outlet 141b is closed, and to a second position where the second air outlet 141b is opened and the first air outlet 141a is closed, thereby realizing air delivery from different directions.

[0057] When cooling, the rotating guide plate 40 can be controlled to be in the first position to send air horizontally from the first air outlet 141a; when heating, the rotating guide plate 40 can be controlled to be in the second position to send air downward from the second air outlet 141b.

[0058] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5 The rotating guide plate 40 includes a plurality of baffles 41 arranged at intervals along the circumferential direction. The plurality of baffles 41 includes a first baffle 411 and a second baffle 412.

[0059] When the guide plate 40 is rotated to the first position, the first baffle 411 is offset from the first air outlet 141a, and the second baffle 412 blocks the second air outlet 141b, so that air is blown out from the first air outlet 141a; when the guide plate 40 is rotated to the second position, the first baffle 411 blocks the first air outlet 141a, and the second baffle 412 is offset from the second air outlet 141b, so that air is blown out from the second air outlet 141b.

[0060] In this application, a plurality of baffles 41 are provided on the rotating guide plate 40. The opening and closing of the air outlet 141 by the relative or staggered relationship between the baffles 41 and the air outlet 141 is realized by the rotating guide plate 40.

[0061] In some embodiments, refer to Figure 4 The first and second parts of the air outlet panel 14 can be divided as follows: Projecting onto a plane perpendicular to the center line of the air outlet panel 14, define line m as parallel to the height direction and tangent to the front end of the air outlet panel 14, and line n as perpendicular to the height direction and tangent to the bottom of the air outlet panel 14. The line passing through the intersection of lines m and n and passing through the center of the air outlet panel 14 is the dividing line. The two sides of the dividing line are the first part and the second part of the air outlet panel 14, respectively.

[0062] In some embodiments, the air outlet panel 14 may be formed by partially bending the top plate 11. The manufacturing process is relatively simple and the manufacturing cost is low.

[0063] In some embodiments, continue to refer to Figure 2 and Figure 3The bottom rear end of the air outlet panel 14 can be connected to the water collection tray 21. The water collection tray 21 includes an air outlet side wall 211 near the air outlet 141, and the bottom rear end of the air outlet panel 14 and the top end of the air outlet side wall 211 can be connected by fasteners such as screws.

[0064] In some embodiments, the air outlet panel 14 does not protrude from the plane containing the bottom surface of the base plate 12. The air outlet panel 14 may be located above the plane containing the bottom surface of the base plate 12. In this way, in some installation scenarios, the base plate 12 of the indoor air conditioning unit can be placed on the ceiling, avoiding instability when the bottom of the air outlet panel 14 contacts the ceiling.

[0065] In some embodiments, refer to Figure 6 The space between two adjacent baffles 41 is a connecting port 42, which includes a first connecting port 42a and a second connecting port 42b.

[0066] The two ends of the multiple baffles 41 in the circumferential direction are the first end and the second end, respectively, with the first end located above the second end; starting from the first end, the first baffle 411 and the first connecting port 42a are arranged alternately; starting from the second end, the second baffle 412 and the second connecting port 42b are arranged alternately.

[0067] The first baffle 411 has the same number as the first air outlet 141a, and the first connecting port 42a has the same number as the first air outlet 141a. The second baffle 412 has the same number as the second air outlet 141b, and the second connecting port 42b has the same number as the second air outlet 141b.

[0068] When the guide plate 40 is rotated to the first position, the first connecting port 42a is connected to the first air outlet 141a; when it is rotated to the second position, the second connecting port 42b is connected to the second air outlet 141b.

[0069] In some embodiments, the side of the baffle 41 facing the air outlet panel 14 abuts against the inner side of the air outlet panel 14, so that during the rotation of the rotating guide plate 40, the baffle 41 blocks the air outlet 141 by contacting the air outlet panel 14.

[0070] In some embodiments, refer to Figure 4 and Figure 6 The rotation center line of the rotating guide plate 40 coincides with the center line of the air outlet panel 14.

[0071] Projecting onto a plane perpendicular to the rotation center line of the rotating guide plate 40, the central angle corresponding to the overall outline of the multiple air outlets 141 is A, and the central angle corresponding to the overall outline of the multiple baffles 41 is B, where B ≥ A + γ, and γ is the central angle corresponding to a single baffle 41. This satisfies the opening and closing function of the baffles 41 on the air outlets 141. When B = A + γ, the area occupied by the baffles 41 in the circumferential direction is minimized.

[0072] Specifically, the line connecting the top of the uppermost air outlet 141 to point O is OJ, and the line connecting the rear end of the last air outlet 141 to point O is OK. The angle between lines OJ and OK is A. The line connecting the top of the uppermost baffle 41 to point O is OG, and the line connecting the rear end of the last baffle 41 to point O is OH. The angle between lines OG and OH is B.

[0073] In some embodiments, the center of the circle corresponding to the air outlet 141 is α, and the central angle corresponding to the interval between two adjacent air outlets 141 is β. The central angle corresponding to the connecting port 42 is δ. γ+δ=α+β.

[0074] In some embodiments, γ > α. When γ > α, that is, the arc length of the baffle 41 is greater than the arc length of the air outlet 141, the baffle 41 can effectively block the air outlet 141.

[0075] For example, α=β=15°, γ=16°, δ=14°. When the rotating guide plate 40 changes from the second position to the first position, it rotates 15° clockwise. When the rotating guide plate 40 changes from the first position to the second position, it rotates 15° counterclockwise.

[0076] In some embodiments, refer to Figure 7 The rotating guide plate 40 includes support plates 43 connected to both ends of the baffle 41 along its length. The support plates 43 are perpendicular to the rotation center line of the rotating guide plate 40. The length direction of the baffle 41 is perpendicular to its height direction and its front-to-back direction.

[0077] The support plate 43 is used for rotatable connection with the housing 10. A rotating shaft 4321 can be provided on the support plate 43, and the rotating shaft 4321 is inserted into the housing 10.

[0078] In some embodiments, the support plate 43 includes a support plate body 431. The support plate body 431 is fan-shaped. The center of the support plate body 431 is the rotation center of the rotating guide plate 40. A baffle 41 is connected between the arcuate ends of the two support plates 43.

[0079] The support plate 43 includes a connecting portion 432, which is connected to the center of the support plate body 431. The connecting portion 432 is arc-shaped with the rotation center of the rotating guide plate 40 as the center, and its two ends in the circumferential direction are respectively connected to the two sides in the circumferential direction of the support plate body 431. A rotating shaft 4321 is provided on the connecting portion 432.

[0080] In some embodiments, the rotation of the rotating guide plate 40 can be driven by a motor. The motor is connected to a rotating shaft 4321 of the rotating guide plate 40 via a gear transmission mechanism.

[0081] The motor outputs rotational force and transmits the rotational force to the rotating guide plate 40 through a gear transmission mechanism.

[0082] The motor can be connected to the housing 10 by fasteners such as screws. The output shaft of the motor is connected to the drive gear, and the rotating shaft 4321 of the rotating guide plate 40 is connected to the driven gear. The drive gear and the driven gear mesh.

[0083] The drive structure that drives the rotating guide plate 40 to rotate is also applicable to the drive structure of the air guide plate at the air outlet of the air conditioner in the prior art.
