Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to a ventilation device for air conditioning equipment. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air in a building or structure. An air conditioner typically consists of a compressor, condenser, evaporator, and one-way valve capillary assembly.

[0003] Existing air conditioning deflector designs primarily rely on up-and-down swinging to adjust the opening angle of the air outlet. However, in specific usage scenarios, to create a comfortable environment and prevent cold air from blowing directly onto the human body, users often need to fine-tune the deflector to form a small angle with the bottom or top of the air outlet. This operation often results in the airflow either being directly aimed at the human body or blowing completely upwards towards the ceiling, thus limiting the flexibility of the airflow direction. It is impossible to achieve simultaneous and even airflow coverage of the entire space from both the top and bottom of the air outlet. The existing air conditioning outlet adjustment method does not fully utilize the airflow space at the top and bottom of the air outlet, and cannot achieve airflow adjustment across the entire area. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ventilation device for air conditioning equipment to solve the problems existing in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ventilation device for an air conditioning unit, comprising an air outlet duct, an upper air outlet plate on one side of the air outlet duct, a lower connecting plate inside the air outlet duct, a lower air outlet plate at the bottom of the upper air outlet plate, a first motor on one side of the upper air outlet plate, a first gear fixedly connected to one side of the first motor, a transmission gear plate at the bottom of the first gear, an upper connecting plate fixedly connected to the bottom of the transmission gear plate, a lower connecting plate fixedly connected to the top of the lower air outlet plate, a first fixing block fixedly connected to the top of the lower connecting plate, a telescopic rod on one side of the first fixing block, a telescopic device fixedly connected to one side of the telescopic rod, a second fixing block fixedly connected to one side of the telescopic device, a movable groove inside the bottom of the upper air outlet plate, an upper water outlet groove inside the movable groove, and a movable rod fixedly connected to one side of the upper water outlet groove.

[0006] Furthermore, a fixed wall is fixedly connected to one side of the air outlet pipe, and a sealant is fixedly connected to the other side of the air outlet pipe. A lower water outlet groove is opened at the bottom inside the air outlet pipe, and a water outlet pipe is fixedly connected to the bottom of the lower water outlet groove.

[0007] Furthermore, the lower linkage plate has an upper linkage plate at its top, and a rotating shaft is fixedly connected to the top of the upper linkage plate. A movable plate is located on one side of the lower linkage plate, and a second motor is located at the top of the movable plate. A threaded rod is fixedly connected to the bottom of the second motor, and a guide rod is located on one side of the threaded rod. A connecting rod is fixedly connected to one side of the movable plate. A first air guide vane is fixedly connected to the top of the upper linkage plate, and a connecting spring is fixedly connected to one side of the first air guide vane. A connecting piece is fixedly connected inside the first air guide vane. A second air guide plate is fixedly connected to the bottom of the lower linkage plate, and a groove is formed on one side of the second air guide plate. A toothed groove is formed at the top of the lower linkage plate, and a second gear is located at the top of the lower linkage plate. A third motor is fixedly connected to one side of the second gear.

[0008] Furthermore, the output shaft of the first motor is fixedly connected to the first gear, the first gear and the transmission gear plate mesh with each other, the transmission gear plate is movably connected to the upper air outlet plate through the upper connecting plate, the second fixed block is fixedly connected to the inner wall of the air outlet pipe, the groove opened in the movable groove is arc-shaped, and the upper water outlet groove is movably connected to the upper air outlet plate through the movable rod.

[0009] Furthermore, the water outlet pipe is fixedly connected to an external water outlet device.

[0010] Furthermore, the first air guide plate is fixedly connected to the upper linkage plate via a rotating shaft, and the first air guide plate and the second air guide plate are movably connected via a connector and a connecting spring. The top of the lower linkage plate and the bottom of the upper linkage plate are provided with toothed grooves, and the second gear meshes with the second fixed block.

[0011] Furthermore, the movable plate has an internal telescopic groove, the area of ​​which is larger than that of the upper linkage plate, and the threaded rod and guide rod are fixedly connected to the inner wall of the air outlet pipe.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention, by incorporating structures such as air outlet panels, enables the first motor to rotate the first gear, moving the upper air outlet panel upwards, thus reserving sufficient space for its movement. The lower air outlet panel moves in the opposite direction to the upper air outlet panel, thus reserving sufficient space for its movement. The extension and retraction of the telescopic device is controlled externally, causing the upper and lower air outlet panels to open outwards. This configuration allows the first motor and the telescopic device to drive the rotation angle of the upper and lower air outlet panels. Thus, according to the exhaust requirements, different angles can be adjusted by the upper and lower air outlet panels to achieve different air outlet angles at the top and bottom of the exhaust duct.

[0014] 2. This invention, through the inclusion of structures such as air guide plates, allows gas to flow out between the first and second air guide plates, which are adjacent but not connected to each other by the same connecting piece. Activating the third motor causes the lower and upper linkage plates to move left and right via the meshing of the second gear and its tooth groove, changing the distance between the first and second air guide plates. The first and second air guide plates not only guide the gas flow but also control the size of the air outlet between them by rotating at different air outlet angles, thereby controlling the gas flow rate. Activating the second motor causes the threaded rod to rotate, driving the movable plate to move on the threaded rod and guide rod, thus changing the height of the lower and upper linkage plates. By adjusting the height and angle of the lower and upper linkage plates, the first and second air guide plates, and the air conditioner air can be more evenly distributed throughout the room, improving overall comfort.

[0024] Reference Figures 1 to 7 This invention provides a ventilation device for an air conditioning unit, including an air outlet duct 1. The device is characterized by an upper air outlet plate 2 on one side of the air outlet duct 1, a lower linkage plate 3 inside the air outlet duct 1, a lower air outlet plate 201 at the bottom of the upper air outlet plate 2, a first motor 202 on one side of the upper air outlet plate 2, a first gear 203 fixedly connected to one side of the first motor 202, a transmission gear plate 204 at the bottom of the first gear 203, and an upper connecting plate 205 fixedly connected to the bottom of the transmission gear plate 204. The lower air outlet plate... A lower connecting plate 206 is fixedly connected to the top of 201. A first fixing block 207 is fixedly connected to the top of the lower connecting plate 206. A telescopic rod 2081 is provided on one side of the first fixing block 207. A telescopic device 208 is fixedly connected to one side of the telescopic rod 2081. A second fixing block 209 is fixedly connected to one side of the telescopic device 208. An movable groove 212 is opened inside the bottom of the upper air outlet plate 2. An upper water outlet groove 210 is provided inside the movable groove 212. A movable rod 211 is fixedly connected to one side of the upper water outlet groove 210.

[0025] In a preferred embodiment, a fixed wall 101 is fixedly connected to one side of the air outlet pipe 1, and a sealant 102 is fixedly connected to the other side of the air outlet pipe 1. A lower water outlet groove 103 is opened at the bottom inside the air outlet pipe 1, and a water outlet pipe 1031 is fixedly connected to the bottom of the lower water outlet groove 103.

[0026] In a preferred embodiment, the lower linkage plate 3 has an upper linkage plate 301 at its top, and a rotating shaft 3011 is fixedly connected to the top of the upper linkage plate 301. A movable plate 305 is provided on one side of the lower linkage plate 3, and a second motor 302 is provided at the top of the movable plate 305. A threaded rod 303 is fixedly connected to the bottom of the second motor 302, and a guide rod 304 is provided on one side of the threaded rod 303. A connecting rod 306 is fixedly connected to one side of the movable plate 305. A first air guide vane 307 is fixedly connected to the top of the upper linkage plate 301, and a connecting spring 3071 is fixedly connected to one side of the first air guide vane 307. A connecting piece 3072 is fixedly connected inside the first air guide vane 307. A second air guide plate 308 is fixedly connected to the bottom of the lower linkage plate 3, and a groove 3081 is provided on one side of the second air guide plate 308. A toothed groove 309 is provided at the top of the lower linkage plate 3, and a second gear 310 is provided at the top of the lower linkage plate 3. A third motor 311 is fixedly connected to one side of the second gear 310.

[0027] Reference Figure 1-5 The upper air outlet plate 2 is fixedly connected to the upper connecting plate 205. The transmission gear plate 204 meshes with the first gear 203. The first motor 202 is turned on to make the first gear 203 rotate, which moves the upper air outlet plate 2 upward, thereby reserving enough space for the upper air outlet plate 2 to move. The lower air outlet plate 201 moves in the opposite direction to the upper air outlet plate 2, thereby reserving enough space for the lower air outlet plate 201 to move.

[0028] The extension and retraction of the telescopic device 208 is controlled by an external electrical system, causing the upper air outlet plate 2 and the lower air outlet plate 201 to open outward. This configuration allows the first motor 202 and the telescopic device 208 to drive the rotation angle of the upper air outlet plate 2 and the lower air outlet plate 201. Thus, according to the exhaust demand, different angles can be adjusted by the upper air outlet plate 2 and the lower air outlet plate 201 to achieve different air outlet effects at the upper and lower parts of the exhaust pipe 1. When the upper air outlet plate 2 is extended outward, due to its weight, the upper water outlet trough 210 is vertically downward, and water droplets on the surface of the upper air outlet plate 2 fall into the upper water outlet trough 210. Water droplets on the surface of the lower air outlet plate 201 fall into the lower water outlet trough 103 and are discharged through the water outlet pipe 1031.

[0029] In this embodiment, it is necessary to specifically add that: the output shaft of the first motor 202 is fixedly connected to the first gear 203, the first gear 203 and the transmission gear plate 204 mesh with each other, the transmission gear plate 204 is movably connected to the upper air outlet plate 2 through the upper connecting plate 205, the second fixed block 209 is fixedly connected to the inner wall of the air outlet pipe 1, the slot opened in the movable groove 212 is arc-shaped, the upper water outlet groove 210 is movably connected to the upper air outlet plate 2 through the movable rod 211, the extension and retraction of the telescopic device 208 is controlled by external electricity, and the water outlet pipe 1031 is fixedly connected to the external water outlet device.

[0030] Reference Figure 6 and 7 Gas flows out from between the first guide vane 307 and the second guide plate 308, which are adjacent but not connected to each other in the same connector 3072. The third motor 311 is turned on, and the second gear 310 meshes with the tooth groove 309, causing the lower linkage plate 3 and the upper linkage plate 301 to move left and right, changing the distance between the first guide vane 307 and the second guide plate 308. The first guide vane 307 and the second guide plate 308 not only guide the gas flow direction, but also control the size of the air supply opening between the first guide vane 307 and the second guide plate 308 by rotating different sizes of air outlet angles, thereby controlling the gas flow rate.

[0031] By activating the second motor 302, the threaded rod 303 is rotated, which drives the movable plate 305 to move on the threaded rod 303 and the guide rod 304, thereby changing the height of the lower linkage plate 3 and the upper linkage plate 301. By adjusting the height and angle of the lower linkage plate 3, the upper linkage plate 301, the first air guide 307 and the second air guide plate 308, the air conditioning air can be distributed more evenly in the room, improving the overall comfort.

[0032] In this embodiment, it is necessary to specifically add that: the first air guide plate 307 is fixedly connected to the upper linkage plate 301 via the rotating shaft 3011; the first air guide plate 307 and the second air guide plate 308 are movably connected via the connector 3072 and the connecting spring 3071; the top of the lower linkage plate 3 and the bottom of the upper linkage plate 301 are provided with toothed grooves 309; the second gear 310 meshes with the second fixed block 209; the movable plate 305 has a telescopic groove inside; the telescopic groove inside the movable plate 305 is larger than the area of ​​the upper linkage plate 301; and the threaded rod 303 and the guide rod 304 are fixedly connected to the inner wall of the air outlet pipe 1.

[0033] The working principle of this invention is as follows: When using this device, the first motor 202 is turned on to rotate the first gear 203, which moves the upper air outlet plate 2 upward, thus reserving sufficient movement space for the upper air outlet plate 2. The lower air outlet plate 201 moves in the opposite direction to the upper air outlet plate 2, thus reserving sufficient movement space for the lower air outlet plate 201. The extension and retraction of the telescopic device 208 is controlled by external electricity, causing the upper air outlet plate 2 and the lower air outlet plate 201 to open outward. This configuration allows the first motor 202 and the telescopic device 208 to drive the upper air outlet plate 2 and the lower air outlet plate 201 to open outward. The rotation angles of the upper air outlet plate 2 and the lower air outlet plate 201 are adjusted according to the exhaust demand to achieve different air outlet effects at different angles in the upper and lower parts of the exhaust pipe 1. When the upper air outlet plate 2 is extended outward, due to its weight, the upper water outlet trough 210 is vertically downward, and water droplets on the surface of the upper air outlet plate 2 fall into the upper water outlet trough 210. Water droplets on the surface of the lower air outlet plate 201 fall into the lower water outlet trough 103 and are discharged through the water outlet pipe 1031.

[0034] Gas flows out between the first guide vane 307 and the second guide plate 308, which are adjacent but not connected to each other by the same connector 3072. The third motor 311 is activated, and the second gear 310 meshes with the tooth groove 309, causing the lower linkage plate 3 and the upper linkage plate 301 to move left and right, changing the distance between the first guide vane 307 and the second guide plate 308. The first guide vane 307 and the second guide plate 308 not only guide the gas flow but also control the airflow direction by rotating the first guide vane 307 at different angles. The size of the air outlet between the 07 and the second air guide plate 308 controls the airflow rate. By starting the second motor 302, the threaded rod 303 is rotated, which drives the movable plate 305 to move on the threaded rod 303 and the guide rod 304, thereby changing the height of the lower linkage plate 3 and the upper linkage plate 301. By adjusting the height and angle of the lower linkage plate 3, the upper linkage plate 301, the first air guide plate 307 and the second air guide plate 308, the air conditioning air can be more evenly distributed in the room, improving the overall comfort.
