DETAILED DESCRIPTION

[0024] Reference Figure 1-7 , a dynamic combined energy-saving dehumidification system, comprising an energy-saving dehumidification device, and a latent heat recovery device located in the energy-saving dehumidification device, referring to Figure 1The latent heat recovery device includes a heat recovery device box 1 and a bent pipe 2 arranged in the heat recovery device box 1, referring to Figure 2 As shown, a gas-liquid separation mechanism and a condensate recovery device are provided on the bending tube 2, and the gas-liquid separation mechanism is connected to the condensate recovery device through a lower pressure rod 10 that passes through the bending tube 2, wherein one end of the lower pressure rod 10 is connected to a lifting block 11, so that as the lifting block 11 rises and falls, the lower pressure rod 10 can be driven to rise and fall together, and the condensate recovery device below is triggered to start.

[0025] The heat recovery device box 1 is respectively provided with a fourth pipe opening 6, a first pipe opening 3 and a second pipe opening 4 connected to the bent pipe 2 end to end, and a third pipe opening 5 connected to the gas-liquid separation mechanism. The condensate recovery device is connected to the outside through a hose. The heat recovery device box 1 is filled with liquid refrigerant, so that the refrigerant turned into gas will go out from the third pipe opening 5 and be compressed by the compressor 20.

[0026] The gas-liquid separation mechanism includes a covering sleeve 7 sleeved on the top of the bending tube 2, and a plurality of heat-conducting rods 20 inserted into the side wall of the bending tube 2. The covering sleeve 7 includes a first sleeve 71 and a second sleeve 72. The liquid inlet pipe 9 is located at the bottom between the first sleeve 71 and the second sleeve 72, and is used to connect the heat recovery box 1 and the space between the first sleeve 71 and the second sleeve 72. Figure 3-4 It is shown that such a configuration can ensure that when the hot air entering the bending tube 2 passes through the heat-conducting rod 20, the heat is conducted by the heat-conducting rod 20 to the first sleeve 71 and the second sleeve 72, and the liquid refrigerant originally located in the first sleeve 71 and the second sleeve 72 is heated to a gaseous state. In this way, the gaseous refrigerant will be located in the space above the first sleeve 71 and the second sleeve 72. Since the pressure in the first sleeve 71 and the second sleeve 72 increases at this time, the lifting block 11 located in the liquid inlet pipe 9 will be continuously lifted.

[0027] A T-shaped liquid inlet pipe 9 is provided between the first sleeve 71 and the second sleeve 72. A liquid blocking mechanism is provided in the liquid inlet pipe 9. Figure 5 As shown, the liquid-blocking mechanism includes a lifting block 11 that slides up and down in the liquid inlet pipe 9, a limiting ring 12 for limiting the lifting block 11, and a side pipe 14 opened on the side wall of the liquid inlet pipe 9. A first bracket 15 is fixed in the liquid inlet pipe 9, and a first return spring 13 is connected between the lifting block 11 and the first bracket 15. When the lifting block 11 in the liquid inlet pipe 9 is lifted up, the lifting block 11 is continuously compressed, and when the lifting block 11 reaches above the liquid inlet of the side pipe 14, the originally blocked side pipe 14 will be opened, and the first sleeve 71 and the second sleeve 72 will begin to be filled with liquid refrigerant. Under the action of the first return spring 13, the lifting block 11 will drop again and block the side pipe 14, and then the lifting block 11 will lift and lower together with the lower pressure rod 10 during the continuous reciprocating up and down movement.

[0028] Reference Figure 6 As shown, the tops of the first sleeve 71 and the second sleeve 72 are both provided with an outlet pipe 8 connected to the third pipe opening 5, a blocking block 19 is provided below the outlet pipe 8 to block the outlet pipe 8, and a second inclined chamfer is provided on the top of the blocking block 19, and a first inclined chamfer 18 adapted to the second inclined chamfer is provided at the bottom of the outlet pipe 8, a second bracket 16 is provided in the outlet pipe 8, and a second return spring 17 is connected between the second bracket 16 and the blocking block 19. It should be noted that the material density of the blocking block 19 is less than that of the liquid refrigerant, so that the blocking block 19 will float on the liquid refrigerant. When there is gaseous refrigerant on the first sleeve 71 and the second sleeve 72, at this time The blocking block 19 will fall down and open the first inclined chamfer 18 that was originally blocked, allowing the gaseous refrigerant to be discharged from above, and the liquid refrigerant that enters the first sleeve 71 and the second sleeve 72 from the side pipe 14 can squeeze the gaseous refrigerant in the first sleeve 71 and the second sleeve 72 out of the first sleeve 71 and the second sleeve 72. When the gaseous refrigerant in the first sleeve 71 and the second sleeve 72 is discharged, the air outlet pipe 8 will be closed again. This arrangement can prevent the liquid refrigerant from absorbing heat and gasifying. Due to the inability to be discharged in time, it will mix with the surrounding cold refrigerant and become liquid again, and then it cannot be compressed by the compressor.

[0029] The condensate recovery device includes a movable groove 22 provided at the bottom of the inner wall of the bending tube 2, two squeezing and pushing plates 21 sliding symmetrically in the movable groove 22, and a stretching sealing belt 26 arranged between two adjacent squeezing and pushing plates 21, so as to effectively prevent the sliding hole 25 from being exposed when the two squeezing and pushing plates 21 move in opposite directions, so as to prevent the hot air in the bending tube 2 from leaking. A water-absorbing sponge 27 for absorbing condensed water is arranged on the opposite side of the two squeezing and pushing plates 21 and located in the movable groove 22. The arrangement of the water-absorbing sponge 27 can effectively prevent the moisture of the hot air with water vapor from being condensed. Drainage mechanisms are arranged on both sides of the movable groove 22. Figure 7 The drain mechanism includes a downpipe 28, a lightweight ball 32 disposed above the downpipe 28, and a ball groove 31 opened at the top of the downpipe 28 and adapted to the lightweight ball 32. A third bracket 29 is provided in the downpipe 28, and the third bracket 29 is connected to the lightweight ball 32 through a third return spring 30. A sliding hole 25 is provided at the bottom of the movable groove 22. The down-pressing rod 10 passes through the stretch sealing belt 26 and the movable groove 22. The down-pressing rod 10 is connected to the down-pressing rod 10 through the support rod 23 and the pillow block 24. The bottoms of the squeezing and pushing plates 21 on both sides of the rod 10 are connected, so that when the lower pressing rod 10 is pressed down, the squeezing and pushing plates 21 on both sides can be opened and the squeezing of the water-containing absorbent sponge 27 can be completed. It should be noted that when the water-containing absorbent sponge 27 is squeezed, the lightweight balls 32 will float up due to the buoyancy, thereby opening the originally closed downpipe 28, which can achieve a drainage effect and solve the problem that the water is condensed, and the water vapor still remains in the latent heat recovery device after the latent heat is utilized, affecting the subsequent cooling.

[0030] The working principle of the present invention is as follows: when the energy-saving dehumidification device is working, the hot air with water vapor passes through the bent tube 2 in the heat recovery device box 1, so that the heat of the hot air in the bent tube 2 is transferred to the first sleeve 71 and the second sleeve 72, and the liquid refrigerant originally located in the first sleeve 71 and the second sleeve 72 is heated to a gas state, and the gaseous refrigerant will be discharged from the air outlet pipe 8, which will also cause the lower pressure rod 10 to continuously rise and fall, and then drive the squeezing plate 21 to squeeze the water-absorbing sponge 27 full of water, and discharge the water from the downpipe 28.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
