Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air guide device and an air conditioner indoor unit. Background Art

[0002] Air conditioners are used to regulate indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. Air conditioners consist of a vapor compression refrigeration cycle system consisting of an evaporator, condenser, compressor, throttling device, and other necessary components. The air conditioner outputs cold / hot air through a fan to achieve cooling and heating of the indoor environment.

[0003] Most existing air conditioner indoor units are equipped with an air guide device at the air outlet, usually an air guide plate, which is used to guide the wind direction. For example, when the air outlet of the air conditioner indoor unit is in a horizontal strip shape, the air guide plate can be in a horizontal strip shape so that it can rotate around a horizontal circumference to adjust the up and down air outlet direction of the air outlet, that is, to adjust the pitch angle of the air outlet airflow with the horizontal plane, so that the air blows forward, forward and upward, forward and downward, or downward.

[0004] Existing air conditioner indoor units largely adopt this air guide plate structure, which has a single structure and lacks innovation. Utility Model Content

[0005] The purpose of the utility model is to provide an air guide device and an air conditioner indoor unit which overcome the above problems or at least partially solve the above problems.

[0006] The utility model aims to solve the problem that the wind guide device of the existing air conditioner indoor unit has a monotonous structure and lacks innovation.

[0007] Another purpose of the utility model is to solve the problem that the existing wind guide device cannot guide the wind in multiple directions at the same time.

[0008] A further object of the utility model is to design a simple and efficient driving mechanism for the above-mentioned air guide device.

[0009] On the one hand, the utility model provides an air guide device for an indoor unit of an air conditioner, the air guide device comprising:

[0010] A first air guide plate, rotatably disposed at the air outlet of the air conditioner indoor unit, for guiding the wind direction;

[0011] a second air guide plate, rotatably disposed at the air outlet of the air conditioner indoor unit, for guiding the wind direction, and having a rotation axis parallel to the rotation axis of the first air guide plate; and

[0012] The driving mechanism is used to drive the first air guide plate and the second air guide plate to rotate synchronously and make the first air guide plate and the second air guide plate rotate in opposite directions.

[0013] Optionally, the rotation axes of the first air guide plate and the second air guide plate are respectively located at the edges of the first air guide plate and the second air guide plate, and the two rotation axes are adjacent to each other, so that the first air guide plate and the second air guide plate rotate in an open manner.

[0014] Optionally, the driving mechanism comprises:

[0015] A first gear, fixedly connected to the first air guide plate, and used to drive the first air guide plate to rotate;

[0016] A second gear, fixedly connected to the second air guide plate, for driving the second air guide plate to rotate, the first gear meshing with the second gear so that the two gears rotate in opposite directions; and

[0017] The motor is configured to directly or indirectly drive the first gear or the second gear to rotate.

[0018] Optionally, the driving mechanism further comprises:

[0019] A transmission gear fixedly connected to the rotating shaft of the motor; and

[0020] The rack is meshed with one of the first gear and the second gear, and is meshed with the transmission gear, so that when the motor drives the transmission gear to rotate, the transmission gear drives the rack to translate, thereby rotating the first gear and the second gear.

[0021] Optionally, the number of teeth of the transmission gear is greater than the number of teeth of the first gear and the second gear.

[0022] Optionally, the first gear and the second gear have different numbers of teeth, so that the rotation speeds of the first air guide plate and the second air guide plate are different.

[0023] Optionally, the first gear is mounted on one end of the first air guide plate along the direction of the rotation axis, and the other end of the first air guide plate is provided with a first shaft for rotatably mounting on a casing of the air conditioner indoor unit;

[0024] The second gear is mounted on one end of the second air guide plate along the direction of the rotation axis, and the other end of the second air guide plate is provided with a second shaft for being rotatably mounted on the casing of the air conditioner indoor unit.

[0025] On the other hand, the utility model also provides an air conditioner indoor unit, which includes:

[0026] a housing having an air outlet for discharging air; and

[0027] In the wind guide device as described in any one of the above items, the first wind guide plate and the second wind guide plate are rotatably arranged at the air outlet to guide the wind direction.

[0028] Optionally, the air outlet is opened on the front side of the housing; and

[0029] The rotation axes of the first air guide plate and the second air guide plate both extend in the transverse direction of the housing.

[0030] Optionally, the air-conditioning indoor unit is of embedded type, and is used to be embedded in a preset chamber.

[0031] In the air conditioner and its air guide device of the utility model, the air guide device includes a first air guide plate and a second air guide plate. The first air guide plate and the second air guide plate can be rotatably installed at the air outlet of the indoor unit of the air conditioner to guide the wind direction. In addition, the air guide device also includes a driving mechanism. The driving mechanism is used to drive the first air guide plate and the second air guide plate to rotate synchronously, and to make the first air guide plate and the second air guide plate turn in opposite directions. In this way, the air flow at the air outlet of the indoor unit of the air conditioner is blown out in two directions under the guidance of the first air guide plate and the second air guide plate, which is convenient for the needs of users in certain occasions.

[0032] For example, for an embedded air conditioner indoor unit, it is not desirable for the wind to blow directly on the human body, so the wind guide device of the utility model is particularly suitable. Specifically, the rotation axis of the first wind guide plate and the second wind guide plate can be extended along the lateral direction of the housing, and one of the first wind guide plate and the second wind guide plate can be used to send air upwards and the other to send air downwards, so as to avoid the outlet airflow blowing directly forward on the human body, causing discomfort to the human body.

[0033] Furthermore, in the air conditioner indoor unit and its air guide device of the utility model, the rotation axes of the first air guide plate and the second air guide plate are respectively located at the edges of the first air guide plate and the second air guide plate, and the two rotation axes are adjacent, so that the first air guide plate and the second air guide plate rotate in a split manner, so that the air flow is divided into two streams, which are blown out under the guidance of the first air guide plate and the second air guide plate, respectively, to surround the user who is directly in front of or directly below the air conditioner indoor unit, forming an embracing air supply effect. In addition, the utility model sets the two rotation axes adjacent to each other, which is also convenient for the design of the drive mechanism.

[0034] Furthermore, in the air-conditioning indoor unit and its air guide device of the utility model, the driving mechanism utilizes the first gear and the second gear to respectively drive the first air guide plate and the second air guide plate, and makes the first gear and the second gear mesh. The motor only needs to drive one of the first gear and the second gear to make the first gear and the second gear rotate synchronously in opposite directions. The structure is simple and the control is precise.

[0035] Furthermore, in the air conditioner indoor unit and the air guide device thereof of the utility model, the driving mechanism also includes a transmission gear and a rack. The motor transmits power to the first gear or the second gear through the transmission gear and the rack, so that the position of the motor can be appropriately away from the air outlet of the air conditioner indoor unit, so that the motor has enough installation space. In addition, the effect of adjusting the rotation speed can be achieved by designing the gear ratio between the gears.

[0051] The embodiment of the utility model provides an air guide device for an indoor unit of an air conditioner.

[0052] The indoor unit of the air conditioner is the indoor part of the split air conditioner or the indoor terminal model of the central air conditioner. The air conditioner is used to regulate the indoor air, including regulating the temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air, etc. The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device and other necessary components to form a vapor compression refrigeration cycle system, so as to output cold air / hot air through a fan to achieve cooling and heating of the indoor environment. The embodiment of the utility model does not impose any limitation on the specific form of the indoor unit of the air conditioner, and the air conditioner can be various forms of household air conditioners, commercial central air conditioners, etc. Specifically, the specific form of the indoor unit of the air conditioner can be various forms such as wall-mounted, vertical, integral, and patio-type.

[0053] Figure 1 1 is a schematic structural diagram of an air guide device 30 for an indoor unit of an air conditioner according to an embodiment of the utility model; Figure 2 yes Figure 1 A magnified image of point A; Figure 3 This is a schematic diagram of an indoor unit of an air conditioner according to an embodiment of the utility model when it is embedded in a cabinet; Figure 4 yes Figure 3 A schematic diagram of the structure shown in another viewing angle with the first air guide plate 31 and the second air guide plate 32 opened; Figure 5 yes Figure 3 a schematic cross-sectional view of the structure shown; Figure 6 yes Figure 5 Schematic diagram of the first air guide plate 31 and the second air guide plate 32 after adjusting the air guide angle.

[0054] like Figures 1 to 6 As shown, the air guide device 30 used for the indoor unit of the air conditioner in the embodiment of the utility model can generally include a first air guide plate 31 , a second air guide plate 32 and a driving mechanism 33 .

[0055] The first air guide plate 31 is rotatably disposed at the air outlet 212 of the air conditioner indoor unit to guide the wind direction. The second air guide plate 32 is rotatably disposed at the air outlet 212 of the air conditioner indoor unit to guide the wind direction. The first air guide plate 31 and the second air guide plate 32 are both plate-shaped, and further shapes and structures are not limited in this embodiment. The rotation axis x2 of the second air guide plate 32 is parallel to the rotation axis x1 of the first air guide plate 31, with reference to Figure 1 .

[0056] The driving mechanism 33 is used to drive the first air guide plate 31 and the second air guide plate 32 to rotate synchronously, and to make the first air guide plate 31 and the second air guide plate 32 rotate in opposite directions. The embodiment of the utility model uses one driving mechanism 33 to drive two air guide plates (the first air guide plate 31 and the second air guide plate 32) to rotate, so that the structure of the driving mechanism 33 is simpler and more efficient.

[0057] In the embodiment of the utility model, the air flow from the air outlet 212 of the indoor unit of the air conditioner is blown out in two directions under the guidance of the first air guide plate 31 and the second air guide plate 32, which is convenient for users in certain occasions.

[0058] For example Figures 3 to 5 As shown, for an embedded air conditioner indoor unit, the rotation axes of the first air guide plate 31 and the second air guide plate 32 can be extended along the horizontal direction of the housing 21, so that the first air guide plate 31 is located above the second air guide plate 32. In this way, the first air guide plate 31 can be adjusted to extend forward and upward, and the second air guide plate 32 can be adjusted to extend forward and downward, so that the first air guide plate 31 can be used to send air upward, and the second air guide plate 32 can be used to send air downward, so as to avoid the outlet air flow blowing forward directly on the human body, causing discomfort to the human body. For other types of air conditioner indoor units, the air guide device 30 of the utility model embodiment also has corresponding effects, which will not be introduced one by one here.

[0059] Of course, the wind guide angles can also be adjusted by rotating the first wind guide plate 31 and the second wind guide plate 32. Figure 5 status, Figure 6 The wind guide angles of the first wind guide plate 31 and the second wind guide plate 32 are changed, so that the wind guide angles of the first wind guide plate 31 and the second wind guide plate 32 are more vertical.

[0060] In addition, the embodiment of the utility model only utilizes one driving mechanism 33 to drive two air guide plates (the first air guide plate 31 and the second air guide plate 32) to rotate synchronously, thereby simplifying the driving mechanism 33 and saving costs and the internal space of the air conditioner indoor unit.

[0061] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the rotation axes x1 and x2 of the first air guide plate 31 and the second air guide plate 32 can be located at the edges of the first air guide plate 31 and the second air guide plate 32 respectively. The two rotation axes x1 and x2 are adjacent to each other so that the first air guide plate 31 and the second air guide plate 32 rotate in a split manner. In this way, the air flow is divided into two streams, which are blown out under the guidance of the first air guide plate 31 and the second air guide plate 32 respectively, and surround the user who is directly in front of or directly below the air conditioner indoor unit, forming an embracing air supply effect. Figure 5For example, since the first air guide plate 31 and the second air guide plate 32 rotate in an open manner, the air flow is divided into two upper and lower streams during air guiding.

[0062] Furthermore, the embodiment of the utility model arranges the two rotation axes adjacent to each other, which also facilitates the design of the driving mechanism 33, making the structure of the driving mechanism 33 more compact and small, thereby avoiding occupying too much of the already cramped internal space of the air-conditioning indoor unit.

[0063] In some other embodiments of the present invention (not shown), the rotation axes of the first air guide plate 31 and the second air guide plate 32 may be respectively away from the edges of the first air guide plate 31 and the second air guide plate 32, for example, they may be set at the center of the first air guide plate 31 or the second air guide plate 32.

[0064] In some embodiments of the present invention (not shown), the driving mechanism may include two motors, and the two motors are respectively used to drive the first air guide plate 31 and the second air guide plate 32 to rotate.

[0065] In some preferred embodiments of the present invention, Figure 1 and Figure 2 As shown, the driving mechanism 33 includes a first gear 335, a second gear 336 and a motor 331. The first gear 335 is fixedly connected to the first air guide plate 31, and is used to drive the first air guide plate 31 to rotate. The second gear 336 is fixedly connected to the second air guide plate 32, and is used to drive the second air guide plate 32 to rotate. The first gear 335 and the second gear 336 are meshed so that the two directions are opposite. The motor 331 is configured to directly or indirectly drive the first gear 335 or the second gear 336 to rotate. The motor 331 is a forward and reverse motor, so that the first air guide plate 31 and the second air guide plate 32 can swing back and forth between two extreme states.

[0066] Furthermore, the motor 331 is preferably a stepping motor so as to more accurately control the rotation angle, thereby accurately adjusting the positions of the first air guide plate 31 and the second air guide plate 32 .

[0067] In the embodiment of the utility model, the driving mechanism 33 utilizes the first gear 335 and the second gear 336 to respectively drive the first air guide plate 31 and the second air guide plate 32, and makes the first gear 335 and the second gear 336 mesh. The motor 331 only needs to drive one of the first gear 335 and the second gear 336 to make the first gear 335 and the second gear 336 rotate synchronously in opposite directions. The structure is simple and the control is precise.

[0068] The motor 331 is configured to directly or indirectly drive the first gear 335 or the second gear 336 to rotate, and various solutions may be adopted.

[0069] For example, the rotating shaft of the motor 331 may be directly connected to the first gear 335 or the second gear 336 to achieve direct drive.

[0070] Or, in a more preferred embodiment, Figure 2 As shown, the driving mechanism 33 further includes a transmission gear 332 and a rack 333. The transmission gear 332 is fixedly connected to the rotating shaft of the motor 331. The rack 333 is meshed with one of the first gear 335 and the second gear 336, and is meshed with the transmission gear 332, so that when the motor 331 drives the transmission gear 332 to rotate, the transmission gear 332 drives the rack 333 to translate, thereby rotating the first gear 335 and the second gear 336.

[0071] The air outlet 212 of the indoor unit of the air conditioner is located at the front side or the lower side of the housing 21, and an air duct 215 communicating with the air outlet 212 is provided inside the housing 21. Due to the obstruction of the air duct 215, the internal space of the housing 21, especially the space around the air outlet 212, is extremely limited. The embodiment of the utility model transmits power through the transmission gear 332 and the rack 333, so that the position of the motor 331 can be appropriately away from the air outlet 212 of the indoor unit of the air conditioner, so that the motor 331 has enough installation space.

[0072] In addition, the embodiment of the utility model can also achieve the effect of adjusting the rotation speed by designing the gear ratio between the gears. For example, the number of teeth of the transmission gear 332 can be greater than the number of teeth of the first gear 335 and the second gear 336, so that the rotation speed of the first gear 335 and the second gear 336 is less than the rotation speed of the motor 331, so as to achieve the effect of slow rotation of the first air guide plate 31 and the second air guide plate 32.

[0073] In some embodiments, the number of teeth of the first gear 335 and the second gear 336 can be made the same so that the rotation speeds of the first air guide plate 31 and the second air guide plate 32 are the same. After the motor 331 rotates a preset angle, the rotation angles of the first air guide plate 31 and the second air guide plate 32 are the same.

[0074] In other embodiments, the first gear 335 and the second gear 336 may have different numbers of teeth to make the first air guide plate 31 and the second air guide plate 32 rotate at different speeds. In this way, after the motor 331 rotates by a preset angle, the first air guide plate 31 and the second air guide plate 32 rotate at different angles.

[0075] In some embodiments, Figure 1 and Figure 2As shown, the first gear 335 can be mounted on one end of the first air guide plate 31 along the direction of the rotation axis x1, and the other end of the first air guide plate 31 is provided with a first shaft 312 for rotatably mounting on the housing 21 of the air conditioner indoor unit. Specifically, the housing 21 can be provided with a corresponding hole (not shown) to cooperate with the first shaft 312. The second gear 336 is mounted on one end of the second air guide plate 32 along the direction of the rotation axis x2, and the other end of the second air guide plate 32 is provided with a second shaft 322 for rotatably mounting on the housing 21 of the air conditioner indoor unit. Specifically, the housing 21 can be provided with a corresponding hole (not shown) to cooperate with the second shaft 322.

[0076] Another aspect of the present utility model embodiment provides an air-conditioning indoor unit.

[0077] The indoor unit of the air conditioner comprises a housing 21 and an air guide device 30 as in any of the above embodiments. The housing 21 has an air outlet 212 for discharging air. The first air guide plate 31 and the second air guide plate 32 are rotatably arranged at the air outlet 212 for guiding the wind direction.

[0078] The indoor unit of the air conditioner is the indoor part of the split air conditioner or the indoor terminal model of the central air conditioner. The air conditioner is used to regulate the indoor air, including regulating the temperature, humidity, air quality of the air, humidifying, dehumidifying, introducing fresh air, etc. The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device and other necessary components to form a vapor compression refrigeration cycle system, so as to output cold air / hot air through a fan to achieve cooling and heating of the indoor environment. The embodiment of the utility model does not impose any limitation on the specific form of the indoor unit of the air conditioner, and the air conditioner can be various forms of household air conditioners, commercial central air conditioners, etc. Specifically, the specific form of the indoor unit of the air conditioner can be various forms such as wall-mounted, vertical, integral, patio, embedded, etc.

[0079] In some embodiments, the air conditioner indoor unit 20 is embedded, and is used to be embedded in a preset chamber. The chamber can be a chamber of a cabinet, a wardrobe or other cabinets. Alternatively, the chamber is a chamber formed by digging a groove in a building wall. The embodiment of the utility model does not limit the chamber. The embedded installation makes the air conditioner indoor unit 20 more hidden and does not affect the overall decoration style of the room.

[0080] Figures 3 to 6 An embodiment of an embedded type air conditioner indoor unit is illustrated.

[0081] like Figures 3 to 6 As shown, the air conditioner indoor unit 20 includes a housing 21, a fan 23, and a heat exchanger 22. The housing 21 is provided with an air inlet 211 for air intake and an air outlet 212 for air discharge, and a first air guide plate 31 and a second air guide plate 32 are rotatably arranged at the air outlet 212 for guiding the wind direction.

[0082] The chamber is the chamber 101 of the cabinet 10. One side of the cabinet 10 is open. The air conditioner indoor unit 20 is embedded in the cabinet 10, and the front side of the air conditioner indoor unit faces the open side of the cabinet 10 so that the air inlet 211 and the air outlet 212 can take in and out air.

[0083] The casing 21 is embedded in the cabinet 10 and is used to accommodate the main components of the air conditioner indoor unit 20, including the fan 23, the heat exchanger 22, the electronic control module, etc. The casing 21 is formed with an air duct 215. The fan 23 is arranged in the casing 21, and is used to cause the air in the casing 21 to enter the casing 21 through the air inlet 211 to form an inlet airflow. The heat exchanger 22 is arranged in the casing 21, and is used to exchange heat with the inlet airflow to form a heat exchange airflow. The heat exchange airflow flows to the air outlet 212 through the air duct 215. When the air conditioner is running in the cooling mode, the heat exchange airflow is a cold airflow. When the air conditioner is running in the heating mode, the heat exchange airflow is a hot airflow. Of course, the air conditioner can have only a cooling function, or have both cooling and heating functions.

[0084] In some embodiments, Figures 3 to 6 As shown, the air outlet 212 is opened at the front side of the housing 21, and the rotation axes of the first air guide plate 31 and the second air guide plate 32 both extend in the lateral direction of the housing 21. In this way, the first air guide plate 31 and the second air guide plate 32 can be used to send air upward and downward to prevent cold air / hot air from blowing forward directly on the human body and making the human body feel uncomfortable.

[0085] In some embodiments, the air outlet 212 is disposed at the lower front portion of the housing 21. The air inlet 211 is provided at the upper front portion and the top portion of the housing 21 to increase the amount of air intake. When installed inside the cabinet 10, a space 1011 may be provided between the top surface of the housing 21 and the inner top wall of the cabinet 10 to allow indoor air to enter the air inlet 211 at the top of the housing 21 through the space 1011.

[0086] In some embodiments, the first air guide plate 31 and the second air guide plate 32 may be configured to close the air outlet 212 .
