Description

Technical Field

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

[0002] Currently, air conditioner indoor units have adjustable air guide vanes at their air outlets. These vanes typically use a multi-stage transmission structure with a motor and connecting rods to open and close. However, these vanes and drive mechanisms have the following technical drawbacks: First, they involve numerous transmission components, require high assembly precision, and have high production and assembly costs. Over long-term use, dust accumulation can cause the transmission to jam or even completely seize, severely affecting the normal operation of the air guide function. Second, the drive mechanism generates significant noise during operation. Third, the solid structure of the air guide vane, due to its high heat transfer efficiency, allows its surface to cool rapidly below the dew point under cooling conditions, leading to condensation. Therefore, there is an urgent need for an air guide vane assembly that is structurally simple, has high operational stability, low noise, and prevents condensation, in order to improve the overall performance of air conditioning products and the user experience. Utility Model Content

[0003] In view of the above problems, this utility model is proposed to provide an air conditioning indoor unit and air conditioner that overcomes or at least partially solves the above problems.

[0004] One objective of this invention is to solve the problems of complex structure, high manufacturing cost, and easy condensation on the surface of the air guide plate drive mechanism of existing air conditioner indoor units.

[0005] Specifically, this utility model provides an indoor unit for an air conditioner, comprising:

[0006] The body has an air outlet formed on it;

[0007] An air guide plate is rotatably mounted at the air outlet. The air guide plate includes a first sidewall and a second sidewall disposed opposite to each other, and an air inlet is formed between the first sidewall and the second sidewall. When the pressure in the air inlet increases, the elongation of the first sidewall in the width direction is greater than the elongation of the second sidewall in the width direction, so that the air guide plate bends.

[0008] An air pump, the outlet of which is connected to the inflation chamber, is configured to adjust the air pressure in the inflation chamber to control the degree of bending of the air guide plate.

[0009] Optionally, a pleated structure is formed on the first sidewall; the pleated structure is composed of multiple connecting pieces connected in sequence.

[0010] Optionally, the air guide plate is mounted at the air outlet via a rotating shaft, and the rotating shaft is located at the upper part of the air outlet;

[0011] The first sidewall is located on the side of the air guide plate away from the air outlet.

[0012] Optionally, the air guide plate is configured such that when the air pressure inside the air guide plate is a first air pressure, the air guide plate is flat and perpendicular to the plane where the air outlet is located; when the air pressure inside the air guide plate is a second air pressure, the air guide plate is curved and the concave surface of the air guide plate faces the air outlet, wherein the second air pressure is greater than the first air pressure.

[0013] Optionally, the first sidewall and the second sidewall are made of a flexible material; and / or

[0014] The elastic modulus of the material of the first sidewall is less than that of the material of the second sidewall.

[0015] Optionally, the air pump is connected to the air pump via a vent pipe;

[0016] The ventilation pipe is equipped with a pressure sensor and a solenoid valve. The pressure sensor and the solenoid valve are electrically connected to the control module. The control module is used to control the opening and closing of the solenoid valve and the opening degree according to the pressure obtained by the pressure sensor, so as to adjust the air pressure in the air guide plate.

[0017] Optionally, the air vent of the inflation chamber is located on the inner wall of the air guide plate near the rotating shaft.

[0018] Optionally, the body includes a front shell and a rear shell, the rear shell has a front opening, the front shell is disposed at the front opening of the rear shell, and the air outlet is disposed on the front shell;

[0019] An air inlet is also formed on the body, the air inlet is disposed on the front shell, and the air inlet is located above the air outlet.

[0020] Optionally, the front shell and the rear shell are detachably connected, and the air pump is disposed on the inner wall of the front shell.

[0021] On the other hand, this utility model also provides an air conditioner, including an outdoor unit and an indoor unit as described in any of the above.

[0022] In this invention, during the operation of the indoor air conditioning unit, the air pump dynamically adjusts the air pressure in the inflation chamber to change the bending shape of the air guide plate. When the air pump injects air into the inflation chamber, the increased chamber pressure causes the tensile deformation of the first sidewall in the width direction to be significantly greater than that of the second sidewall, pushing the air guide plate to bend towards the second sidewall. By controlling the inflation / deflation volume of the air pump in real time, the chamber pressure can be precisely adjusted to achieve dynamic control of the bending arc of the air guide plate, thereby achieving continuous stepless adjustment of the air delivery angle. This invention uses pneumatic drive instead of the traditional gear linkage mechanism, which not only eliminates the friction noise of mechanical transmission but also reduces the number of parts, significantly reducing manufacturing costs and failure risks. The hollow heat insulation layer formed by the inflation chamber can block the conduction of cold energy, preventing the surface temperature of the air guide plate from dropping sharply below the dew point, fundamentally suppressing condensation. In addition, the structural characteristics of no mechanical wear ensure that the equipment remains stable during long-term use, and maintenance only requires checking the airtightness without complex disassembly and assembly. As can be seen, this utility model integrates the dynamic adjustment of the air guide plate, noise reduction optimization and anti-condensation function into one, which significantly improves the overall energy efficiency compared with the existing technology, solves many industry problems such as complex mechanical transmission, noise pollution and condensation, and achieves a dual breakthrough of structural simplification and functional upgrade.

[0035] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and refer to Figures 2 to 6 This utility model embodiment provides

[0036] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and refer to Figures 2 to 6 This embodiment of the utility model provides an indoor air conditioning unit 100, which includes a body 110, an air guide plate 120, and an air pump 140. An air outlet 114 is formed on the body 110. The air guide plate 120 is rotatably mounted at the air outlet 114. The air guide plate 120 includes a first sidewall 121 and a second sidewall 122 disposed opposite to each other, with an inflation chamber formed between the first sidewall 121 and the second sidewall 122. When the pressure in the inflation chamber increases, the elongation of the first sidewall 121 in the width direction is greater than the elongation of the second sidewall 122 in the width direction, causing the air guide plate 120 to bend. The outlet of the air pump 140 communicates with the inflation chamber, and the air pump 140 is configured to adjust the air pressure in the inflation chamber to control the degree of bending of the air guide plate 120. That is, the air pump 140 is the driving mechanism for the air guide plate 120.

[0037] When the indoor unit 100 of the air conditioner is running, the air pump 140 adjusts the air pressure in the inflation chamber to change the bending shape of the air guide plate 120. When the air pump 140 injects gas into the inflation chamber, the internal pressure of the chamber increases. Due to the difference in the elastic modulus of the materials or the difference in structural thickness between the first sidewall 121 and the second sidewall 122, the tensile deformation of the first sidewall 121 along the width direction under the action of air pressure is significantly greater than that of the second sidewall 122, causing the air guide plate 120 to bend towards the second sidewall 122. By controlling the inflation / deflation volume of the air pump 140 in real time, the pressure in the inflation chamber can be precisely adjusted, thereby dynamically changing the bending arc of the air guide plate 120 and realizing continuous adjustment of the air delivery angle.

[0038] In this embodiment, firstly, an air pump 140 replaces the traditional mechanical transmission mechanisms such as gears and connecting rods, eliminating gear meshing friction and mechanical collision noise, significantly reducing operating noise (especially suitable for quiet scenarios), while also reducing the number of parts, manufacturing costs, and failure rates. Secondly, the air guide plate 120 achieves stepless bending through air pressure adjustment, allowing precise control of the airflow diffusion angle and air delivery range, improving comfort under different operating conditions. Thirdly, the hollow heat insulation layer formed by the air-filled cavity blocks the rapid conduction of cold energy from the inside of the air guide plate 120 to the surface, preventing the surface temperature from dropping sharply below the dew point and fundamentally suppressing condensation. Fourthly, there are no mechanically worn parts, resulting in high long-term stability, and maintenance only requires checking the airtightness, without complex disassembly and assembly. Therefore, this embodiment integrates the adjustment function of the air guide plate 120 with the anti-condensation design through a pneumatically driven deformation mechanism, solving multiple problems in traditional technologies such as complex transmission, high noise, and condensation, combining functional innovation with improved practicality.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, a pleated structure is formed on the first sidewall 121; the pleated structure is composed of a plurality of connecting pieces 1212 connected in sequence.

[0040] In this embodiment, the connecting piece 1212 can extend along the length of the first sidewall 121. The corrugated structure of the first sidewall 121 is formed by multiple connecting pieces 1212 connected in sequence to form a stretchable corrugated shape, which significantly enhances the elastic deformation capability of the first sidewall 121. When the air chamber is pressurized, the corrugated structure makes the air guide plate 120 more sensitive to bending response and the deformation arc smoother and more controllable; at the same time, the corrugated structure avoids the risk of material fatigue or cracking by dispersing local stress, thus extending the service life of the air guide plate 120. In addition, this design can achieve the requirement of large deformation without high-precision molds, reducing the processing difficulty and manufacturing cost, and the corrugated shape naturally shrinks after exhaust, making it easy for the air guide plate 120 to be reset or stored.

[0041] In some embodiments of this utility model, a pleated structure 1211 is formed on the first sidewall 121 of the air guide plate 120; the pleated structure 1211 is composed of a plurality of connecting pieces 1212 connected in sequence. The first sidewall 121 and the second sidewall 122 are made of flexible materials. Specifically, the first sidewall 121 and the second sidewall 122 can be made of the same flexible material, or they can be made of different flexible materials. For example, the elastic modulus of the material of the first sidewall 121 is less than that of the material of the second sidewall 122.

[0042] In some embodiments of this invention, the air guide plate 120 is made of a flexible material. The flexible material can be thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), silicone material, or polyester elastomer (PES), etc. The entire air guide plate 120 is made of a flexible material, which helps to reduce the manufacturing difficulty of the air guide plate 120.

[0043] In some embodiments of this invention, the elastic modulus of the material of the first sidewall 121 is less than that of the material of the second sidewall 122. Specifically, the first sidewall 121 has a low elastic modulus, high flexibility, and large deformation. The second sidewall 122 has a high elastic modulus, strong rigidity, and small deformation. The difference in deformation between the two sidewalls forces the air guide plate 120 to bend as a whole toward the second sidewall 122 (the side with smaller deformation), thereby achieving air delivery angle adjustment. This embodiment achieves bending of the air guide plate 120 through the difference in material properties, reducing processing costs.

[0044] In some embodiments of this utility model, the air guide plate 120 is rotatably mounted at the air outlet via a rotating shaft, which is located at the lower or middle part of the air outlet 114.

[0045] like Figures 2 to 5 As shown, in some embodiments of this utility model, the air guide plate 120 is rotatably mounted at the air outlet via a rotating shaft, which is located above the air outlet 114. A first sidewall 121 is located on the side of the air guide plate 120 away from the air outlet 114. In this embodiment, the rotating shaft is designed to be high up, and the weight of the air guide plate 120 generates a natural restoring torque through the rotating shaft, reducing the working air pressure required for the air pump 140 to maintain its bent state, thereby reducing energy consumption.

[0046] like Figures 2 to 5 As shown, in some embodiments of this utility model, the air guide plate 120 is configured such that when the air pressure inside the air guide plate 120 is a first air pressure, the air guide plate 120 is flat and perpendicular to the plane where the air outlet 114 is located; when the air pressure inside the air guide plate 120 is a second air pressure, the air guide plate 120 is curved and the concave surface of the air guide plate 120 faces the air outlet 114, that is, the second sidewall 122 is concave and faces the air outlet 114. The second air pressure is greater than the first air pressure.

[0047] This embodiment achieves flexible adaptation of the air supply mode by controlling the shape switching of the air guide plate 120 through air pressure control. When the air pressure inside the air guide plate 120 is the first air pressure, the air guide plate 120 is in the first state; when the air pressure inside the air guide plate 120 is the second air pressure, the air guide plate 120 is in the second state. By adjusting the air pressure inside the air guide plate 120, the air guide plate 120 can be maintained in the first state, the second state, and any swing angle between the two. Specifically, when the air guide plate 120 maintains the first air pressure, it remains flat and perpendicular to the plane of the air outlet 114, which can output concentrated high-speed airflow to meet the needs of rapid cooling; when the air pump 140 pressurizes to the second air pressure, the air guide plate 120 is driven to bend by asymmetric deformation, which diffuses the airflow into a wide-area air supply, improving the uniformity of air supply coverage and comfort.

[0048] like Figure 3 and Figure 6 As shown, in some embodiments of this utility model, the air pump 140 is connected to the air pump 140 via the air pipe 130. The air pipe 130 is equipped with an air pressure sensor and a solenoid valve. The air pressure sensor and the solenoid valve are electrically connected to the control module. The control module is used to control the opening and closing of the solenoid valve and the opening degree according to the air pressure obtained by the air pressure sensor, so as to adjust the air pressure in the air guide plate 120.

[0049] In this embodiment, by monitoring and automatically adjusting the air pressure inside the air guide plate 120 in real time, the bending amplitude of the air guide plate 120 is ensured to be precisely controllable, avoiding the problem of unstable oscillation caused by overcharging or undercharging.

[0050] like Figure 2 and Figure 6 As shown, in some embodiments of this utility model, the vent pipe 130 is a flexible hose. That is, the air pump 140 and the air guide plate 120 can be flexibly connected through the flexible hose. With the above arrangement, the noise of the air guide plate 120 during rotation can be further reduced.

[0051] like Figure 6 As shown, in some embodiments of this utility model, the air vent of the inflation chamber is located on the inner wall of the air guide plate 120 near the rotating shaft. Specifically, the outlet of the air pipe 130 is connected to the air vent of the inflation chamber, and the outlet of the air pipe 130 is located near the rotating shaft. In an alternative embodiment, the air vent of the inflation chamber may also be located on the inner wall of the air guide plate 120 away from the rotating shaft.

[0052] Since the air guide plate 120 rotates around the pivot, the area near the air guide plate 120 has the smallest range of positional change. Therefore, placing the vent near the pivot can reduce the length of the vent pipe 130, reduce external leakage of the vent pipe 130, and improve aesthetics.

[0053] like Figures 1 to 6As shown, in some embodiments of this utility model, the body 110 includes a front shell 111 and a rear shell 112, with a front opening on the rear shell 112, the front shell 111 being disposed at the front opening of the rear shell 112, and an air outlet 114 being disposed on the front shell 111.

[0054] Furthermore, in some embodiments of this utility model, an air inlet 113 is also formed on the body 110. The air inlet 113 is disposed on the front shell 111 and is located above the air outlet 114. In this embodiment, both the air inlet 113 and the air outlet 114 are disposed on the front side of the body 110, thereby facilitating the embedded installation of the indoor unit in a cabinet or wall to meet the diverse usage needs of users.

[0055] Furthermore, such as Figure 1 As shown, a panel is provided at the air inlet 113, which is used to open or cover the air inlet 113. The pivot of the panel is located at the lower edge of the panel. In addition, since the pivot of the air guide plate 120 is located at the upper edge of the air outlet 114, the mutual interference between the incoming airflow and the outgoing airflow can be avoided.

[0056] In some embodiments of this utility model, the front shell 111 and the rear shell 112 are detachably connected. Specifically, the front shell 111 and the rear shell 112 can be connected by any feasible connection method, such as threaded connection, snap-fit ​​connection, plug-in connection, magnetic connection, etc. Among them, threaded connection includes bolt connection or screw connection. The detachable connection design of the front shell 111 and the rear shell 112 facilitates the assembly and disassembly of the indoor unit; during maintenance, users can easily disassemble the indoor unit, replace damaged parts or perform internal cleaning, thus extending the service life of the indoor unit.

[0057] like Figure 6 As shown, in some embodiments of this utility model, the front shell 111 and the rear shell 112 are detachably connected, and the air pump 140 is disposed on the inner wall of the front shell 111.

[0058] The air pump 140 is mounted on the front housing 111, which facilitates its installation, inspection, and maintenance. Specifically, during installation, the air pump 140 can be first assembled onto the front housing 111, and then the front housing 111 can be installed onto the rear housing 112. During inspection or maintenance, the front housing 111 can be removed from the rear housing 112 for inspection or maintenance.

[0059] In some embodiments of this utility model, the air conditioner indoor unit 100 is a recessed air conditioner indoor unit, a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, or other types of air conditioner indoor units.

[0060] Preferably, the indoor unit 100 is a recessed indoor unit.

[0061] An embodiment of this utility model also provides an air conditioner, which includes an outdoor unit and an indoor unit 100 as described in any of the above embodiments.

[0062] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
