Description

Technical Field

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

[0002] With the increasing popularity of air conditioning, more and more users are choosing to install central air conditioning in their homes. Ductless air conditioning units, as a type of central air conditioning system, are favored by users for their advantages such as low cost, simple structure, and concealed installation.

[0003] Existing ducted air conditioners are usually installed in the ceiling. They mainly consist of a housing and a fan and heat exchanger installed inside the housing. The housing has an air conditioning inlet and an air conditioning outlet. The fan draws air into the housing from the air conditioning inlet, and after heat exchange by the heat exchanger, the air is conditioned and sent out from the air conditioning outlet.

[0004] However, ducted air conditioners currently on the market typically only have one air outlet on the side of the machine. When using an embedded installation solution, a separate ceiling is required for construction. Moreover, due to structural limitations, the air outlet cannot be concealed. In addition, the airflow direction of the side air outlet is mainly horizontal or oblique, which cannot deliver hot air directly to the ground in heating mode. Due to the rising nature of hot air, the indoor temperature tends to be higher at the top and lower on the ground, resulting in a poor user comfort experience. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, according to embodiments of this disclosure, an air conditioning indoor unit is proposed, comprising: The housing has an air conditioning inlet and an air conditioning outlet, with the air conditioning inlet located on the end wall of the housing. A fan, located inside the housing, is used to draw air into the housing from the air conditioner inlet; A heat exchanger, which is disposed inside the housing, is used for heat exchange with air entering the housing; Under the action of the fan, indoor air enters the housing through the air conditioner inlet, and after heat exchange through the heat exchanger, it is output to the room through the air conditioner outlet. The air conditioner outlet is located on the bottom wall of the housing and at the end away from the air conditioner inlet. An air guide plate is arranged in an arc shape, and the air guide plate extends from or retracts into the housing from the air outlet; A transmission mechanism is connected to the air guide plate and is used to drive the air guide plate to move between a first position and a second position. When the air guide plate is in the first position, the airflow flows towards the end closer to the air conditioner inlet under the guidance of the air guide plate; When the air guide plate is in the second position, the airflow flows away from the top wall of the housing.

[0007] The above technical solution has the following advantages or beneficial effects: By opening the air conditioner outlet on the bottom wall of the casing, air can be delivered from the bottom of the air conditioner, thus eliminating the need for a separate ceiling design as required by traditional ducted air conditioners due to the limitation of side air conditioner outlets. Furthermore, placing the air conditioner outlet at the bottom provides better concealment, satisfying people's pursuit of aesthetics. In addition, this application uses a guide plate that extends or retracts from the air outlet into the casing. When the air conditioner is in cooling mode, a transmission mechanism drives the guide plate to extend out of the casing to the first position. At this time, the cold air flows through the air outlet towards the end near the air inlet under the guidance of the guide plate, achieving a parallel blowing effect to the ceiling. When the air conditioner is in heating mode, a transmission mechanism drives the guide plate to retract into the casing to the second position. At this time, the hot air can be directly discharged from the air outlet, effectively blowing the hot air towards the floor, thus conforming to the comfort principle of a cool head and warm feet.

[0008] According to an embodiment of this disclosure, the central angle of the air guide plate is 90°. When the air guide plate is in the first position, the tangent of the end of the air guide plate away from the air conditioner outlet extends towards the air conditioner inlet.

[0009] The above technical solution has the following advantages or beneficial effects: by setting the central angle of the air guide plate to 90°, when the air guide plate is in the first position, the airflow can be blown out horizontally, and when the air guide plate is retracted into the housing, the airflow can be blown vertically to the ground, thereby enabling more flexible adjustment of the airflow direction from vertical to horizontal, meeting the air supply needs of multiple angles.

[0011] The above technical solution has the following advantages or beneficial effects: by setting the air guide plate to slide along the guide rail, the stability of the air guide plate during the movement can be significantly improved. The structure is simple and labor-saving, and it can ensure that the air guide plate can adjust the air outlet direction smoothly and reliably.

[0012] According to embodiments of this disclosure, the first driving element includes: The rack is arranged in an arc shape and is installed on the side of the air guide plate near the guide rail; The gear meshes with the rack; A first drive motor is installed inside the housing and has a first drive shaft connected to the gear.

[0014] According to embodiments of this disclosure, the transmission mechanism further includes: Multiple rolling bearings are embedded in the sidewall of the guide rail; When the air guide plate slides within the guide rail, rolling friction occurs between the air guide plate and the rolling bearing.

[0015] The above technical solution has the following advantages or beneficial effects: by setting rolling bearings, the frictional resistance between the air guide plate and the guide rail can be effectively reduced, ensuring that the air guide plate slides more smoothly and steadily; the use of rolling bearings reduces friction during sliding, reduces wear, and thus extends the service life of the air guide plate and the guide rail.

[0016] According to embodiments of this disclosure, the transmission mechanism includes: A connecting rod has an extended end and a connecting end that are arranged opposite to each other. The connecting end is rotatably connected to the housing, and the extended end is fixedly connected to the air guide plate. Rotation of the connecting rod drives the air guide plate to rotate. The second driving element is connected to the connecting rod. The driving element is used to drive the connecting rod to rotate, thereby driving the air guide plate to rotate to extend or retract into the housing, so as to adjust the air outlet direction at the air conditioner outlet.

[0017] The above technical solution has the following advantages or beneficial effects: by setting the air guide plate to be driven by a linkage, the linkage rotates under the action of the second driving element and drives the air guide plate to rotate. The structure is simple and labor-saving, and it can ensure that the air guide plate can smoothly and reliably adjust the air outlet direction.

[0018] According to embodiments of this disclosure, the second driving element includes: A second drive motor is installed inside the housing and has a second drive shaft connected to the connecting rod for driving the connecting rod to rotate.

[0019] The above technical solution has the following advantages or beneficial effects: the rotation of the air guide plate is achieved smoothly and reliably by driving the connecting rod through the second drive motor.

[0021] The above technical solution has the following advantages or beneficial effects: by setting two connecting rods to connect to both ends of the air guide plate, the air guide plate can receive uniform support during movement, thereby significantly improving the stability of the air guide plate during movement.

[0022] According to an embodiment of this disclosure, the indoor unit of the air conditioner further includes a light-emitting element disposed inside the housing near the air conditioner outlet; the air guide plate is capable of reflecting the light from the light-emitting element.

[0023] The above technical solution has the following advantages or beneficial effects: by setting a light-emitting body and combining it with the reflective effect of the air guide plate surface, the light from the light-emitting body can be effectively reflected and diffused into the room, thereby realizing the lighting or decorative lighting function; this design allows the air conditioner to not only provide temperature regulation, but also visually enhance the aesthetics of the room and improve the overall comfort of the indoor environment; in addition, since the indoor unit of the air conditioner in this application can be embedded in the ceiling, the appearance of the air conditioner is more concise and neat, saving space.

Detailed Implementation

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] In this application, the indoor unit of the air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0033] The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it as a high temperature and high pressure 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. The expansion valve causes the high temperature and high pressure liquid refrigerant condensed in the condenser to expand into a low pressure liquid refrigerant.

[0034] The indoor heat exchanger evaporates the refrigerant that expands in the expansion valve and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor. The indoor heat exchanger achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled.

[0035] Throughout the entire cycle, the indoor unit of an air conditioner can regulate the temperature of the indoor space. The outdoor unit of an air conditioner indoor unit refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner indoor unit includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0036] The indoor and outdoor heat exchangers function as either condensers or indoor heat exchangers. When the indoor heat exchanger is used as a condenser, the indoor unit of the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an indoor heat exchanger, the indoor unit of the air conditioner functions as a cooler in cooling mode.

[0037] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0038] As attached Figures 1 to 6 As shown, in an illustrative embodiment of the indoor unit of this utility model, the indoor unit includes a housing 100, which forms the appearance of a ducted air conditioner, and the interior of the housing 100 defines a receiving cavity. The housing 100 has a top wall and a bottom wall, and the top wall and the bottom wall of the housing 100 are the two ends of the housing 100 that are arranged opposite each other in the vertical direction.

[0039] As attached Figure 1-3As shown, the housing 100 has an air conditioning inlet 101 and an air conditioning outlet 102 that communicate with the receiving cavity. The air conditioning inlet 101 serves as the inlet for external air to flow into the housing 100, and the air conditioning outlet 102 serves as the outlet for air conditioning air after heat exchange within the housing 100. Indoor air from outside the housing 100 enters the housing 100 through the air conditioning inlet 101 and is finally discharged into the room through the air conditioning outlet 102. An air duct is formed inside the housing 100, located between the air conditioning inlet 101 and the air conditioning outlet 102.

[0040] The air conditioner inlet 101 is located at one end of the housing 100 in the horizontal direction, and the air conditioner outlet 102 is located at the bottom wall of the housing 100 and at the other end of the housing 100 in the horizontal direction away from the air conditioner inlet 101. In order to facilitate the intake of air into the air conditioner inlet 101, an opening can be made at the bottom of the ceiling to connect to the air conditioner inlet 101.

[0041] It should be noted that currently, ducted air conditioners on the market typically only have one air outlet 102 on the side of the machine. When using an embedded installation solution, in order to ensure that the air outlet can connect with the outside, the air outlet 102 needs to protrude from the ceiling, requiring independent ceiling installation. In addition, the air supply direction of the side air outlet 102 is mainly horizontal or oblique, which cannot directly deliver hot air to the ground in heating mode. Due to the rising nature of hot air, the indoor temperature is prone to be higher at the top and lower at the bottom, resulting in a poor user comfort experience.

[0042] To address the aforementioned issues, this application employs the above-described technical solution, where the air inlet 101 is located at one end of the housing 100 in the horizontal direction. Only an opening at the bottom of the ceiling is needed to allow air to enter the air inlet 101 from the bottom. The air outlet 102 is positioned on the bottom wall of the other end of the housing 100 in the horizontal direction, enabling air to be delivered from the bottom of the air conditioner. This eliminates the need for a separate ceiling design required by traditional ducted air conditioners due to the side air outlet 102. Furthermore, placing the air outlet 102 at the bottom provides better concealment, satisfying aesthetic requirements. Additionally, this technical solution allows air conditioning air to be blown vertically from the bottom air outlet 102 towards the floor, effectively directing hot air towards the floor.

[0043] In some embodiments of this application, the indoor unit of the air conditioner includes a fan 200, which is disposed inside the housing 100 and is used to introduce air into the housing 100 from the air conditioner air inlet 101. The fan 200 can be any one of a cross-flow fan 200, an axial fan 200, or a centrifugal fan 200.

[0044] In some embodiments of this application, the indoor unit of the air conditioner includes a heat exchanger 300, which is disposed inside the housing 100 and is used to exchange heat with the air entering the housing 100. The fan 200 can be located either in front of or behind the heat exchanger 300, and its function is to introduce air from the air inlet into the air duct, and after passing through the heat exchanger 300, blow it out from the air outlet.

[0045] In some embodiments of this application, the indoor unit of the air conditioner includes an air guide plate 400, which is arc-shaped and extends from or retracts from the air outlet 102 into the housing 100 to adjust the airflow direction at the air outlet 102. The air guide plate 400 has a first position and a second position, as shown in the attached figure. Figure 1 As shown, when the air guide plate 400 is in the first position, the air guide plate 400 extends outside the housing, and the airflow at the air conditioner outlet 102 flows towards the end closer to the air conditioner inlet 101 under the guidance of the air guide plate 400. (See attached image) Figure 3 As shown, when the air guide plate 400 is in the second position, the air guide plate 400 is located inside the housing 100. At this time, the airflow direction at the air outlet 102 is away from the top wall of the housing 100, that is, it is blown towards the ground perpendicular to the ceiling.

[0046] In some embodiments of this application, the indoor unit of the air conditioner includes a transmission mechanism 500, which is connected to the air guide plate 400 for driving the air guide plate 400 to move, so as to adjust the air outlet direction at the air outlet 102.

[0047] It should be noted that simply setting the air conditioner outlet 102 on the bottom wall of the housing 100 can achieve downward blowing of hot air, but in order to meet the comfort requirements of people, it is necessary not only to achieve downward airflow when heating, but also to achieve horizontal airflow when cooling.

[0048] Therefore, in order to further adjust the airflow direction at the air outlet 102, this application, through the above-mentioned technical solution, sets the air guide plate 400 to extend or retract from the housing 100. When the air conditioner is in cooling operation, the outdoor unit of the air conditioner introduces low-temperature, low-pressure refrigerant into the heat exchanger 300. The air flows through the heat exchanger 300 under the drive of the fan 200, and the temperature decreases. At this time, the air guide plate 400 can be driven to the first position by the transmission mechanism 500, so that the air guide plate 400 extends out of the housing 100. At this time, the cold air passes through the air outlet 102 and is guided by the air guide plate 400. It can flow towards the end near the air inlet 101 of the air conditioner to achieve the effect of horizontal air supply; when the air conditioner is in heating mode, the outdoor unit of the air conditioner introduces high-temperature and high-pressure refrigerant into the heat exchanger 300. The air flows through the heat exchanger 300 under the drive of the fan 200 and the temperature rises. At this time, the air guide plate 400 can be driven to the second position through the transmission mechanism 500, so that the air guide plate 400 retracts into the housing 100. At this time, the hot air can be blown directly from the air outlet 102 perpendicular to the ceiling to the floor, which can effectively blow the hot air to the floor, thus conforming to the comfort principle of the human body with a cool head and warm feet.

[0049] like Figure 1 As shown, in some embodiments of this application, the central angle of the air guide plate 400 is 90°. When the air guide plate 400 is in the first position, the tangent of the end of the air guide plate 400 away from the air conditioner outlet 102 extends toward the direction close to the air conditioner inlet 101; the tangent of the end of the air guide plate 400 close to the air conditioner outlet 102 extends toward the end wall of the housing 100.

[0050] By setting the central angle of the air guide plate 400 to 90° through the above technical solution, the air flow direction can be controlled more precisely. When the air guide plate 400 is in the second position inside the housing 100, the air guide plate 400 can guide the air inside the housing 100 to diffuse downward from the air outlet, avoiding the airflow from blowing directly vertically to the other end face of the housing 100 along its length, thereby improving the air delivery effect. When the air guide plate 400 gradually extends outward from inside the housing 100 to the first position, the air delivery angle can gradually rotate from the vertical downward direction to the horizontal direction, so that the air can be blown out at any angle to meet the needs of various air delivery angles.

[0051] like Figure 4 , 5 As shown, in some embodiments of this application, the transmission mechanism 500 includes a guide rail 501, which is arc-shaped and is installed inside the housing 100 and slidably connected to one side of the air guide plate 400.

[0052] The transmission mechanism 500 includes a first driving element 502, which drives the air guide plate 400 to extend or retract into the housing 100 along the guide rail 501 to adjust the air outlet direction at the air conditioner outlet 102.

[0053] In the above technical solution, by setting the air guide plate 400 to slide along the guide rail 501, the stability of the air guide plate 400 during the movement can be significantly improved. The structure is simple and labor-saving, and it can ensure that the air guide plate 400 can adjust the air outlet direction smoothly and reliably.

[0054] In some embodiments of this application, the first driving element 502 includes a rack 5021, which is arc-shaped and mounted on the side of the air guide plate 400 near the guide rail 501.

[0055] The first driving element 502 includes a gear 5022, which meshes with a rack 5021. The rotation of the gear 5022 can drive the rack 5021 to move.

[0056] The first driving element 502 includes a first driving motor 5023, which is installed inside the housing 100. The first driving motor 5023 has a first driving shaft, which is connected to a gear 5022. The first driving motor 5023 drives the gear 5022 to rotate, and the rotation of the gear 5022 drives the rack 5021 to move.

[0057] In the above technical solution, the first drive motor 5023 drives the rack 5021 through the meshing of the gear 5022 and the rack 5021, thereby realizing the rotation of the air guide plate 400 smoothly and reliably.

[0058] In the above technical solution, by setting the air guide plate 400 to be driven by the rack 5021, the rack 5021 drives the air guide plate 400 to slide along the guide rail 501 under the action of the first driving element 502, which can significantly improve the stability of the air guide plate 400 during the movement. The structure is simple and labor-saving, and it can ensure that the air guide plate 400 can adjust the air outlet direction smoothly and reliably.

[0059] In some embodiments of this application, the transmission mechanism 500 further includes a plurality of rolling bearings 503, which are embedded in the side wall of the guide rail 501; when the air guide plate 400 slides in the guide rail 501, rolling friction occurs between the air guide plate 400 and the rolling bearings 503.

[0060] The above technical solution has the following advantages or beneficial effects: by setting the rolling bearing 503, the frictional resistance between the air guide plate 400 and the guide rail 501 can be effectively reduced, ensuring that the air guide plate 400 slides more smoothly and steadily; the use of the rolling bearing 503 reduces the friction during the sliding process, reduces wear, and thus extends the service life of the air guide plate 400 and the guide rail 501.

[0061] like Figure 6 As shown, in another embodiment, the transmission mechanism 500 includes a connecting rod 504, which has an extended end and a connecting end that are disposed opposite to each other. The connecting end is rotatably connected to the housing 100, and the extended end is fixedly connected to the air guide plate 400. The rotation of the connecting rod 504 drives the air guide plate 400 to rotate.

[0062] The transmission mechanism 500 includes a second driving element, which is connected to the connecting rod 504. The driving element is used to drive the connecting rod 504 to rotate, thereby driving the air guide plate 400 to rotate to extend or retract into the housing 100, so as to adjust the air outlet direction at the air conditioning outlet 102.

[0063] In the above technical solution, the air guide plate 400 is driven by the connecting rod 504. The connecting rod 504 rotates under the action of the second driving element and drives the air guide plate 400 to rotate. The structure is simple and labor-saving, and it can ensure that the air guide plate 400 can adjust the air outlet direction smoothly and reliably.

[0064] In some embodiments of this application, the second driving element includes a second driving motor, which is installed inside the housing 100 and has a second driving shaft connected to the connecting rod 504 for driving the connecting rod 504 to rotate.

[0065] In the above technical solution, the rotation of the air guide plate 400 is achieved smoothly and reliably by driving the connecting rod 504 through the second drive motor.

[0066] In some embodiments of this application, there are two connecting rods 504, which are respectively connected to the opposite ends of the air guide plate 400.

[0067] In the above technical solution, by setting two connecting rods 504 to connect to both ends of the air guide plate 400 respectively, the air guide plate 400 can receive uniform support during the movement, thereby significantly improving the stability of the air guide plate 400 during the movement.

[0068] In some embodiments of this application, the indoor unit of the air conditioner also includes a light-emitting body 600, which is disposed inside the housing 100 near the air conditioner outlet 102; the surface of the air guide plate 400 has a reflective effect, thereby reflecting the light from the light-emitting body 600 for providing room lighting or decorative lighting.

[0069] In the above technical solution, by setting up a light-emitting body 600 and combining it with the reflective effect of the air guide plate 400, the light from the light-emitting body 600 can be effectively reflected and diffused into the room, thereby achieving the function of lighting or decorative lighting. This design allows the air conditioner to not only provide temperature regulation, but also to visually enhance the aesthetics of the room and improve the overall comfort of the indoor environment. In addition, since the indoor unit of the air conditioner in this application can be embedded in the ceiling, the appearance of the air conditioner is more concise and neat, saving space. Combined with the lighting function, the air conditioner not only has the traditional cooling or heating function, but also integrates the function of lighting equipment, enhancing the practicality and aesthetics of the product.

[0070] The light source 600 can be an LED light, an incandescent light, etc.

[0071] In some embodiments of this application, a decorative panel 700 is provided at the bottom of the housing 100, and the decorative panel 700 can be embedded in the ceiling.

[0072] In the above technical solution, by setting a decorative panel 700 at the bottom of the housing 100 and embedding it in the ceiling, the appearance design of the air conditioning system can be effectively improved, the cleanliness and consistency of the ceiling can be maintained, and the overall visual effect of the interior decoration can be enhanced.

[0073] In some embodiments of this application, the indoor unit of the air conditioner also includes a filter 800, which is installed at the air conditioner inlet 101 and is used to filter the indoor air entering the housing 100 from the air conditioner inlet 101.

[0074] The above technical solution has the following advantages or beneficial effects: by installing a filter 800 at the air inlet 101 of the air conditioner, dust, impurities and harmful substances in the air can be effectively removed, ensuring that the air entering the air conditioning system is cleaner; it helps to keep the internal components of the air conditioner clean, reduces dust accumulation, thereby extending the service life of the equipment, and can also improve indoor air quality and enhance the user's health experience.
