Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning diverters, in particular to an air-conditioning diverter with uniform diversion. Background Art

[0002] The traditional air conditioner manifold structure consists of a manifold seat and an end cover. The gas-liquid two-phase mixture of the refrigerant flowing out after throttling by the expansion valve is distributed to each coil through the manifold. In air conditioning equipment, a heat exchanger composed of multiple heat exchange units is widely used to maximize the heat exchange capacity of the heat exchanger. One of its key technologies is to evenly distribute the gas-liquid two-phase mixture of the refrigerant to a heat exchange unit;

[0003] Patent CN110645742A proposes an air-conditioning diverter and an air conditioner, which combines an end cover, a diverter seat, a cyclone and a diverter branch to allow a gas-liquid two-phase mixture of the refrigerant to enter from a diverter inlet, pass through the cyclone, swirl in the cyclone, and be evenly mixed in the swirl chamber, and finally evenly distributed to each branch pipe through the diverter branch on the lower end of the diverter seat. The air-conditioning diverter reduces the influence of gravity of the gas-liquid two-phase mixture of the refrigerant, and effectively improves the diversion uniformity of the air-conditioning diverter.

[0004] In the above scheme, after being evenly mixed by the cyclone, the refrigerant is distributed to the branch pipe from the diversion branch. However, in this process, the refrigerant cannot be guaranteed to be delivered into the diversion branch at the same time, which will also have a certain impact on the uniform effect of the diverter. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an air-conditioning diverter with uniform diversion to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. When the refrigerant needs to be evenly distributed and delivered, the refrigerant is briefly kept in the inner cavity of the connecting ring, which is conducive to the mixing of the refrigerant. At the same time, all the sealing plates are opened, and the time for the refrigerant to pass through each delivery port is the same, so that it can be evenly delivered to each branch channel. The connecting component part is convenient for disassembly and installation.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an air-conditioning diverter with uniform diversion, including a mainstream pipe, a branch pipe seat is provided at the lower end of the mainstream pipe, and a plurality of branch pipe channels are equidistantly opened inside the branch pipe seat, a connecting component is provided between the mainstream pipe and the branch pipe seat, the connecting component includes a connecting ring, a cavity is provided inside the connecting ring, and a bottom plate is fixed to the bottom of the connecting ring, a delivery outlet corresponding to the branch pipe channel is opened on the surface of the bottom plate, and a sealing plate is rotatably connected to the inside of the delivery outlet through a bearing, a sliding rod is fixed at the center of the bottom plate, a fixing component is provided on the outer side of the connecting ring, and the fixing component includes a mounting ring, mounting rings are fixed to the upper and lower ends of the connecting ring, and the mounting ring is fitted with the connecting end of the mainstream pipe and the branch pipe seat.

[0007] Furthermore, the connecting assembly also includes a floating plate, which is slidably sleeved on the surface of the sliding rod, and a return spring is fixed to the bottom of the bottom plate at the outer ring of the sliding rod, and the other end of the return spring is fixedly connected to the floating plate.

[0008] Furthermore, a telescopic rod is rotatably mounted on the bottom of the outer edge of the floating plate via a rotating shaft, and the extended end of the telescopic rod is rotatably connected to one end of the sealing plate via the rotating shaft.

[0009] Furthermore, a mounting plate is symmetrically fixed to the inner wall of the upper end of the connecting ring, and an electric push rod is fixed to the bottom of the mounting plate, the extended end of the electric push rod is in extrusion contact with the top of the floating plate, an electromagnet is installed at the extended end of the electric push rod, and a metal layer is provided at the extended end of the floating plate corresponding to the electric push rod.

[0010] Furthermore, magnet plates are fixed at the upper and lower ends of the bottom plate located at the delivery outlet, and the magnet plates can be adsorbed on the surface of the sealing plate, and the two magnet plates are arranged at opposite positions of the delivery outlet.

[0011] Furthermore, the center of the branch pipe seat is hollow, and the branch pipe channel is inclined outward, and the inlet end of the branch pipe channel corresponds vertically to the delivery outlet.

[0012] Beneficial effects of the utility model:

[0013] 1. When the delivery outlet needs to be opened, the extended end of the electric push rod is retracted, and the floating plate moves upward along the sliding rod under the action of the reset spring. The telescopic rod pulls the sealing plate to rotate to open the delivery outlet, and the refrigerant pre-stored in the connecting ring passes through the delivery outlet at the same time to maintain the uniformity of the refrigerant delivery.

[0014] 2. The utility model closes the delivery port by adsorbing two sets of reverse magnet plates and sealing plates, thereby preventing the refrigerant liquid from flowing into the branch pipe channel and staying briefly in the cavity of the connecting ring.

[0015] 3. Compared with the prior art, when the refrigerant needs to be evenly distributed and delivered, the utility model allows the refrigerant to stay briefly in the inner cavity of the connecting ring, which is conducive to the mixing of the refrigerant. At the same time, all the sealing plates are opened, and the time for the refrigerant to pass through each delivery port is the same, so that it can be evenly delivered to each branch channel, and the connecting component part is convenient for disassembly and installation.

The mounting rings 41 are fixed to the upper and lower ends of the connecting ring 31, and the mounting rings 41 are fitted with the connecting ends of the main pipe 1 and the branch pipe seat 2. In this device, the main pipe 1 and the branch pipe seat 2 have the same basic structure as the existing diverter. The connecting component 3 is installed between the main pipe 1 and the branch pipe seat 2. The position of the delivery outlet 33 corresponds to the branch pipe channel 21. The delivery outlet 33 is blocked by the sealing plate 34, and the refrigerant is pre-stored in the cavity of the connecting ring 31. Then, the sealing plates 34 are opened at the same time to evenly deliver the refrigerant into the branch pipe channel 21 to maintain uniform diversion.

[0024] In this embodiment, the connecting assembly 3 also includes a floating plate 38, and the floating plate 38 is slidably sleeved on the surface of the sliding rod 39. The bottom of the bottom plate 32 is located on the outer ring of the sliding rod 39 and is fixed with a return spring 311, and the other end of the return spring 311 is fixedly connected to the floating plate 38. The outer edge bottom of the floating plate 38 is rotatably mounted with a telescopic rod 310 through a rotating shaft, and the extended end of the telescopic rod 310 is rotatably connected to one end of the sealing plate 34 through a rotating shaft. The inner wall of the upper end of the connecting ring 31 is symmetrically fixed with a mounting plate 3 7, and an electric push rod 36 is fixed to the bottom of the mounting plate 37, and the extended end of the electric push rod 36 is pressed and contacted with the top of the floating plate 38, and an electromagnet is installed at the extended end of the electric push rod 36, and the floating plate 38 is provided with a metal layer corresponding to the extended end of the electric push rod 36, and the upper and lower ends of the bottom plate 32 located at the delivery outlet 33 are fixed with magnet plates 35, and the magnet plates 35 can be adsorbed on the surface of the sealing plate 34, and the two magnet plates 35 are arranged at opposite positions of the delivery outlet 33, and the electric push rod 36 is extended when the electric push rod 36 is opened. When the electromagnet is turned on (not numbered in the electromagnet figure), the electromagnet is adsorbed on the top of the floating plate 38, so that the extended end of the electric push rod 36 can drive the floating plate 38 to slide up and down along the slide rod 39, so that the electric push rod 36 can adjust the opening or closing of the sealing plate 34. In the open state, it can be used as a conventional diverter. When the electromagnet is turned off, the extended end of the electric push rod 36 is pressed and contacted with the floating plate 38, pressing the floating plate 38 to the bottom, and the sealing plate 34 is rotated to a flat state through the telescopic rod 310. The magnet plate 35 is adsorbed with the sealing plate 34, thereby closing the delivery port 33 to prevent the refrigerant liquid from flowing into the branch pipe channel 21 and temporarily staying in the cavity of the connecting ring 31. When the delivery port 33 needs to be opened, the extended end of the electric push rod 36 is retracted, and the floating plate 38 moves upward along the sliding rod 39 under the action of the return spring 311. The telescopic rod 310 pulls the sealing plate 34 to rotate and open the delivery port 33. The refrigerant pre-stored in the connecting ring 31 passes through the delivery port 33 at the same time to maintain the uniformity of the refrigerant delivery.

[0025] In this embodiment, the center of the branch pipe seat 2 is hollow, and the branch pipe channel 21 is inclined outward. The inlet end of the branch pipe channel 21 is perpendicular to the delivery port 33, and the branch pipe seat 2 is lotus-shaped, which is convenient for transporting to different locations through the branch pipe channel 21.

[0026] When the device is used, the connecting ring 31 is fixedly installed with the main pipe 1 and the branch pipe seat 2 through the mounting ring 41, the screw 43 and the screw hole 44. The position of the delivery port 33 corresponds to the branch pipe channel 21. When the electromagnet at the extended end of the electric push rod 36 is turned on, the electromagnet is adsorbed on the top of the floating plate 38, so that the extended end of the electric push rod 36 can drive the floating plate 38 to slide up and down along the slide rod 39, so that the opening or closing of the sealing plate 34 is adjusted by the electric push rod 36. In the open state, it can be used as a conventional diverter. When the electromagnet is turned off, the extended end of the electric push rod 36 is squeezed and contacted with the floating plate 38, pressing the floating plate 38 At the bottom, the sealing plate 34 is rotated to a flat shape by the telescopic rod 310, and the upper and lower sets of opposite magnet plates 35 are adsorbed on the sealing plate 34, thereby closing the delivery port 33 to prevent the refrigerant liquid from flowing into the branch pipe channel 21 and temporarily staying in the cavity of the connecting ring 31. When the delivery port 33 needs to be opened, the extended end of the electric push rod 36 is retracted, and the floating plate 38 moves upward along the sliding rod 39 under the action of the reset spring 311. The telescopic rod 310 pulls the sealing plate 34 to rotate, and the delivery port 33 is opened. The refrigerant pre-stored in the connecting ring 31 passes through the delivery port 33 at the same time to maintain uniform diversion.
