Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning outlets, and in particular to a central air-conditioning outlet with a humidifying component. Background Art

[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] A Chinese utility model patent with publication number CN216481300U discloses a humidifying device installed at the air outlet of a central air conditioner; water in a water tank is led out of the water tank through a water pipe, and transferred to an atomizing nozzle through a branch pipe, and the water is atomized by the atomizing nozzle. When the central air conditioner is used to cool the room, the cold air generated by the central air conditioner is output to the room through the air outlet of the air conditioner, and the water mist is blown to diffuse to various places in the room, thereby humidifying the room.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the air conditioner is blowing, the water mist sprayed by the humidifier will be blown onto the guide plate of the air outlet by the wind blown by the central air conditioner. Since the air contains some bacterial molecules, dust, etc., the water mist is easy to gather on the guide plate to form water droplets, which provides a living environment for bacteria and other microorganisms. After a long time, it is easy to affect people's health. In addition, dust gathers on the guide plate, reducing the quality of air outlet. Therefore, it is necessary to improve the design of the related technologies. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a central air-conditioning outlet with a humidifying component.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: a central air-conditioning outlet with a humidification component, including a mounting frame, a humidification nozzle arranged on the top of the mounting frame, and a plurality of louvers arranged in the mounting frame, wherein the louvers are located on the side close to the air outlet of the mounting frame, and the mounting frame is provided with an adjustment mechanism for driving the plurality of louvers to adjust their angles synchronously and a scraping mechanism for scraping debris on the surface of the plurality of louvers at the same time.

[0007] By adopting the above technical solution, the scraping mechanism can scrape away debris on the surfaces of multiple louvers at the same time, changing the situation where water droplets, bacteria, dust and other debris accumulate on the louver surfaces for a long time, which is beneficial to ensuring the air quality of the central air conditioner and ensuring the health of users.

[0008] Furthermore, the scraping mechanism includes a scraping assembly and a power assembly. The number of groups of the scraping assemblies is equal to the number of louvers and the positions correspond one to one. Each group of the scraping assemblies includes an annular scraper mounted on the louver and cooperating with the louver, a fixed block fixed to one side of the annular scraper, a first connecting rod hinged to the top of the fixed block, and a second connecting rod hinged to the end of the first connecting rod away from the fixed block. The power assembly is used to drive multiple second connecting rods to move synchronously so that the multiple annular scrapers can be raised and lowered synchronously.

[0009] By adopting the above technical solution, when using the scraping mechanism to scrape the debris on the surface of the louver, the user only needs to drive multiple second connecting rods to move synchronously through the power component. Under the action of the first connecting rod and the fixed block, multiple annular scrapers are raised and lowered synchronously to scrape bacteria, water droplets, dust and other debris on the surface of the louver, thereby ensuring the cleanliness of the louver and improving the air quality of the central air outlet.

[0010] Furthermore, the power assembly includes a vertical guide rod fixed to the inner top wall of the installation frame, a first motor fixed to the inner top wall of the installation frame, a vertical screw fixed to the output end of the first motor, and a lifting plate jointly arranged on the vertical screw and the vertical guide rod, the vertical screw passes through the lifting plate and is threadedly connected, the vertical guide rod passes through the lifting plate and is slidably fitted, and the bottom of the lifting plate is hinged to one end of a plurality of second connecting rods away from the first connecting rod.

[0011] By adopting the above technical solution, after the user starts the first motor, the first motor drives the vertical screw to rotate. Since the vertical screw is threadedly connected to the lifting plate, the vertical guide rod and the lifting plate are slidingly matched, and multiple second connecting rods are hinged to the bottom of the lifting plate, so that the multiple second connecting rods can drive their corresponding annular scrapers to rise and fall synchronously through the first connecting rod and the fixed block, thereby scraping off the debris on the louver.

[0012] The top of the louver plate is fixed with a rotating rod rotatably connected to the top wall of the mounting frame, and a horizontal plate is fixed on the inner wall of the mounting frame at a position close to the bottom wall of the mounting frame, and the bottom of the louver plate is rotatably connected to the horizontal plate, and the bottom wall of the mounting frame is provided with two symmetrical grooves, and the bottom of the mounting frame is provided with a water outlet hole connected to the groove, and the water outlet hole discharges the accumulated water to the outside through a drain pipe. A wiper assembly is provided in the mounting frame for scraping water scraped off the louver plate into the groove, and the wiper assembly includes an active bevel gear fixed to the lower end of the vertical screw, a transverse screw rotatably installed between the inner walls on both sides of the mounting frame, a driven bevel gear fixedly sleeved on the transverse screw and meshed with the active bevel gear, a transverse guide rod fixed between the inner walls on both sides of the mounting frame, and a scraper installed together on the transverse guide rod and the transverse screw, the transverse screw penetrates the scraper and is threadedly connected to the scraper, the transverse guide rod penetrates the scraper and slidably cooperates, the bottom surface of the scraper abuts against the bottom wall of the mounting frame, and the upper surface of the scraper is lower than the bottom surface of the transverse plate.

[0013] By adopting the above technical solution, during the rotation of the vertical screw, the vertical screw drives the active bevel gear, the driven bevel gear meshing with the active bevel gear, and the transverse screw fixed with the driven bevel gear to rotate. Since the transverse screw is threadedly connected to the scraper, the transverse guide rod penetrates the scraper and slides together, so that the scraper can reciprocate and scrape the water on the bottom wall of the installation frame into the groove, and finally discharge it to the outside through the water outlet and the drain pipe.

[0014] Furthermore, the adjustment mechanism includes an adjustment component and a drive component. The number of groups of the adjustment components is equal to the number of louvers and the positions correspond one to one. Each group of the adjustment components includes a third connecting rod hinged to the top of the louver and a fourth connecting rod hinged to an end of the third connecting rod away from the louver. The drive component is used to drive multiple fourth connecting rods to move synchronously so as to simultaneously adjust the opening and closing angles of multiple louvers.

[0015] Furthermore, the driving assembly includes a second motor fixed on the top wall of the installation frame, a driving gear fixed to the output end of the second motor, a guide block fixed to the top wall of the installation frame, and a movable rod penetrating the guide block and slidingly cooperating with the guide block, and a plurality of latching teeth meshing with the driving gear are arranged at a position of the movable rod close to the driving gear, and the latching teeth are located close to the end of the movable rod, and the end of the fourth connecting rod away from the third connecting rod is hinged to the bottom of the movable rod.

[0016] By adopting the above technical solution, after the user starts the second motor, the second motor drives the driving gear to rotate. Due to the sliding cooperation between the movable rod and the guide block, the locking teeth on the movable rod engage with the driving gear, and the end of the fourth connecting rod away from the third connecting rod is hinged to the bottom of the movable rod, so that the fourth connecting rod pulls the louver through the third connecting rod, so that the louver rotates around the rotating rod to adjust the angles of multiple louvers.

[0017] Furthermore, a C-shaped portion is provided at the bottom of the guide block for sliding cooperation with the movable rod, the bottom height of one side of the C-shaped portion is greater than or equal to the height of the top of the fourth connecting rod, and the other side of the bottom of the C-shaped portion is offset from the end of the fourth connecting rod.

[0018] By adopting the above technical solution and limiting the shape of the C-shaped portion, the normal movement of the movable rod is ensured so that the angle of the louver can be smoothly adjusted.

[0019] Furthermore, the first motor and the second motor are both servo motors.

[0020] In summary, the present invention has the following beneficial effects:

In this application, the scraping mechanism can scrape off the debris on the surfaces of multiple louvers at the same time, changing the situation where water droplets, bacteria, dust and other debris accumulate on the surface of the louvers for a long time, which is beneficial to ensure the air quality of the central air conditioner and the health of the user;

[0022] 2. In the present application, when using a scraping mechanism to scrape off debris on the surface of the louver, the user only needs to drive multiple second connecting rods to move synchronously through the power assembly. Under the action of the first connecting rod and the fixed block, multiple annular scrapers are raised and lowered synchronously to scrape off bacteria, water droplets, dust and other debris on the surface of the louver, thereby ensuring the cleanliness of the louver and improving the air quality of the central air-conditioning outlet.
