Description

Technical Field

[0001] This application relates to the technical field of air dehumidification, and particularly to a fresh air dehumidifier based on a five-constant technology residence. Background Art

[0002] A five-constant technology residence includes control in five aspects: constant temperature, constant humidity, constant oxygen, constant cleanliness, and constant quietness, and realizes the automatic adjustment of the indoor environment through an intelligent management system. A heat pump dehumidifier is a device that uses the heat pump principle for dehumidification. During the dehumidification process, the heat pump dehumidifier first sucks in the wet air indoors, then reduces the air temperature through the evaporator, and the water vapor in the air condenses into liquid water due to encountering the low-temperature surface of the evaporator, thus realizing the dehydration of the air. These liquid waters are then collected and discharged from the system to reduce the humidity of the indoor air.

[0003] However, if there is a large amount of condensed water in the evaporator, or the water vapor in the air flow fails to be completely condensed, after the low-temperature air enters the pipeline of the condenser, it will exchange heat with the external environment, and this heat exchange may cause some of the low-temperature air to condense into liquid water in the pipeline. In the prior art, vertical pipelines are usually set up so that the condensed water can flow back to the evaporator by gravity. If the condensed water does not flow back smoothly, it may cause liquid water to remain in the pipeline, affecting the dehumidification effect and breeding bacteria at the same time.

Detailed implementation manners

[0025] The following further elaborates on this application Figures 1-4 in conjunction with the accompanying drawings.

[0026] An embodiment of this application discloses a fresh air dehumidifier based on a five-constant technology residence. The fresh air dehumidifier includes an evaporator, a condenser, an evaporation chamber in contact with the evaporator, and a condensation chamber in contact with the condenser. The partitions between the evaporator and the evaporation chamber and between the condenser and the condensation chamber have a heat transfer function. When the refrigerant enters the evaporator, it is in a low-pressure and low-temperature state, exchanges heat with the air flow entering the evaporation chamber, evaporates into a gaseous state, and at the same time, the air flow is cooled after absorbing heat; during the process of temperature reduction of the air flow, the relative humidity increases, the water vapor carried in the air flow condenses to form liquid water, and is discharged through the drain pipe in the evaporation chamber. The gaseous refrigerant releases heat in the condenser and changes from a gaseous state to a liquid state; the air flow entering the condensation chamber exchanges heat with the refrigerant and is discharged after being adjusted to a suitable temperature.

[0027] A dehumidification mechanism is fixedly connected between the evaporation chamber and the condensation chamber. The dehumidification mechanism includes an outer pipe 1 and a rotating pipe 2 rotatably arranged inside the outer pipe 1. Specifically, the cross-section of the outer pipe 1 is kidney-shaped, and a rotating cavity 11 for installing the rotating pipe 2 and an air inlet chamber and an air outlet chamber 12 respectively arranged at both ends of the rotating cavity 11 are provided inside the outer pipe 1. The rotating pipe 2 is rotatably arranged inside the rotating cavity 11. Windshield plates 14 are fixedly provided at the positions where both ends of the rotating cavity 11 are respectively connected to the air inlet chamber and the air outlet chamber 12. A connecting shaft 15 is fixedly provided between the two windshield plates 14; the cross-section of the rotating pipe 2 is circular, and the rotating pipe 2 is sleeved on the periphery of the connecting shaft 15 and is rotatably connected to the connecting shaft 15.

[0028] Two fixing plates 16 are symmetrically and fixedly provided inside the rotating pipe 2 along the radial direction of the rotating pipe 2. The fixing plates 16 divide the space inside the rotating pipe 2 into two semi-circular chambers 17. Absorbent media are respectively accommodated in the two semi-circular chambers 17; in this embodiment, the absorbent media can be zeolite. The rotating pipe 2 is a closed pipe body, and two air inlet holes 1 are respectively opened on the two opposite bottom surfaces of the rotating pipe 2. The air inlet holes 1 are arc-shaped, and the two air inlet holes 1 on the same side bottom surface are symmetrically arranged along the radial direction of the rotating pipe 2. When the rotating pipe 2 stops rotating, the two fixing plates 16 are in the horizontal direction, so that the two semi-circular chambers 17 are distributed vertically up and down. Air inlet holes 2 are opened on the windshield plates 14; when the rotating pipe 2 stops rotating, the air inlet holes 1 are aligned with the air inlet holes 2, and the air flow enters the semi-circular chamber 17 from the air inlet chamber and continues to flow into the air outlet chamber 12.

[0029] Specifically, when the rotating pipe 2 stops rotating, one of the semi-circular chambers 17 is located above, and the other semi-circular chamber 17 is located below. The semi-circular chamber 17 located above is used to send the air flow from the steam chamber into the condensation chamber. The air flow contacts the water-absorbing medium in the semi-circular chamber 17 to remove the liquid water carried in the air flow. The semi-circular chamber 17 located below contacts the heat source and is used for dehydrating the water-absorbing medium. The second air inlet hole is located on the upper half of the circular surface of the wind baffle 14, and the air flow enters the upper semi-circular chamber 17 through the second air inlet hole. After the rotating pipe 2 rotates, the first air inlet hole and the second air inlet hole are gradually misaligned; after the two semi-circular chambers 17 alternate positions, the semi-circular chamber 17 located above is used to absorb moisture, and the semi-circular chamber 17 located below performs moisture desorption.

[0030] The rotating cavity 11 opened on the outer pipe 1 runs through the outer pipe 1 vertically; a pipe sleeve 18 is fixedly arranged in the rotating cavity 11, and the rotating pipe 2 is rotatably arranged in the pipe sleeve 18; the pipe sleeve 18 protrudes above and below the rotating cavity 11 vertically. Two air inlet channels 21 are symmetrically and fixedly arranged at the top of the outer pipe 1, and two air outlet channels 22 are symmetrically and fixedly arranged at the bottom of the outer pipe 1. The cross-sections of the air inlet channels 21 and the air outlet channels 22 are both arc-shaped; four connecting through holes are opened on the circumferential side of the pipe sleeve 18, so that the arc surfaces of the air inlet channels 21 and the air outlet channels 22 are both attached to the outer peripheral surface of the rotating pipe 2 through the connecting through holes.

[0031] An evaporation box is fixedly arranged on one side of the evaporator, and the side wall between the evaporation box and the evaporator is made of heat transfer material. A cold air inlet pipe 23 and a cold air outlet pipe 24 which are respectively connected to the side walls of the two air inlet channels 21 are fixedly arranged on the side wall of the evaporation box. A connecting pipe 25 for connecting the two air inlet channels 21 is fixedly arranged on the side walls of the two air inlet channels 21 far away from the evaporation box. Specifically, an air inlet pump and an air outlet pump are respectively arranged on the cold air inlet pipe 23 and the cold air outlet pipe 24; after the air flow enters the evaporation box, it exchanges heat with the refrigerant in the evaporator, enters one of the air inlet channels 21 through the cold air inlet pipe 23, then enters the other air inlet channel 21 and returns to the evaporation box to exchange heat again. The water-absorbing medium exchanges heat with the cold air flow in the air inlet channel 21 to reduce the temperature, and the water-absorbing medium can improve the adsorption efficiency at low temperature.

[0032] On one side of the condenser, a condensation box is fixedly installed, and the side wall between the condensation box and the condenser is made of heat transfer material. On the side wall of the condensation box, a hot gas inlet pipe 26 and a hot gas outlet pipe 27 are fixedly installed, which are respectively connected to the side walls of two air outlet channels 22. On the side walls of the two air outlet channels 22 away from the condensation box, a connecting pipe 25 is fixedly installed to connect the two air outlet channels 22. Specifically, an intake pump and an outlet pump are respectively arranged on the hot gas inlet pipe 26 and the hot gas outlet pipe 27; after the air flow enters the condensation box, it exchanges heat with the refrigerant in the condenser, enters one of the air outlet channels 22 through the hot gas inlet pipe 26, then enters the other air outlet channel 22 and returns to the condensation box for heat exchange again. The water absorption medium exchanges heat with the hot air flow in the air outlet channel 22 to increase the temperature, and the water absorption medium desorbs at high temperature.

[0033] At the bottom of the outer peripheral surface of the pipe sleeve 18, a water outlet tank 28 is fixedly installed, and the pipe sleeve 18 is communicated with the water outlet tank 28. On the outer peripheral surface of the rotating pipe 2, two strip-shaped water outlet holes 3 are symmetrically arranged; the two water outlet holes 3 are respectively communicated with the two semi-circular chambers 17. After the rotating pipe 2 stops rotating, the water outlet hole 3 located below the rotating pipe 2 is communicated with the water outlet tank 28. Specifically, due to the heat exchange with the hot air flow in the air outlet channel 22, the liquid water desorbed by the water absorption medium flows into the water outlet tank 28 through the water outlet hole 3.

[0034] A water outlet valve is arranged in the water outlet hole 3. The water outlet valve includes valve grooves 31 symmetrically arranged on the two hole walls of the water outlet hole 3 and valve plates 32 respectively slidably arranged in the two valve grooves 31. A magnetic strip and a compression spring are fixedly installed in the valve groove 31; the compression spring is fixedly connected to the valve plate 32 and is used to push the valve plate 32 to move towards the outside of the valve groove 31; a metal sheet capable of magnetic adsorption with the magnetic strip is fixedly installed on the side wall of the valve plate 32 facing the valve groove 31. The magnetic strip is an electromagnet; after the magnetic strip is energized, it generates a magnetic attraction effect on the valve plate 32 and drives the valve plate 32 to move towards the inside of the valve groove 31.

[0035] Specifically, a first control switch for controlling the on / off of the magnetic strip is fixedly arranged on the outer wall of the rotating pipe 2; there are two groups of the first control switches, and each group of the first control switches is electrically connected to a group of magnetic strips in two oppositely arranged valve grooves 31. The first control switch includes a first transmission member slidably arranged on the outer peripheral surface of the rotating cylinder along the radial direction of the rotating cylinder. A first transmission groove for accommodating the first transmission member is formed on the outer peripheral surface of the rotating cylinder. A first switch piece capable of making electrical contact is fixedly arranged on the inner wall of the first transmission groove and the side wall of the first transmission member respectively, and the two first switch pieces are respectively electrically connected to the storage battery and the magnetic strip. A second compression spring is fixedly arranged in the first transmission groove, and the second compression spring is fixedly connected to the first transmission member for pushing the first transmission member to move outward from the first transmission groove. A first slot capable of being inserted into the first transmission member is formed on the inner peripheral surface of the pipe sleeve 18. When the first transmission member is inserted into the first slot, the two first switch pieces are in contact, and the magnetic strip is electrified and respectively controls the two valve plates 32 to move toward the relatively outer sides. A chamfer is formed at the top corner position of the first transmission member facing the outside of the first transmission groove for the rotating pipe 2 to leave the first slot by abutting against the outer wall of the first slot when rotating. When the first transmission member abuts against the inner peripheral surface of the pipe sleeve 18, the two first switch pieces are in a misaligned state, the magnetic strip is powered off, and the two valve plates 32 are in contact with each other to make the water outlet valve in a closed state.

[0036] A number of driving components for driving the rotation of the rotating pipe 2 are arranged on both sides of the outer pipe 1 in the rotating cavity 11. The driving component includes a driving wheel 33 rotatably arranged in the outer pipe 1 and a transmission wheel 34 embedded in the outer peripheral surface of the outer pipe 1. A wheel groove is formed on the inner side wall of the rotating cavity 11, and the driving wheel 33 is rotatably arranged in the wheel groove; the driving wheel 33 is meshed with the transmission wheel 34. An axial groove along the axial direction of the outer pipe 1 and penetrating the wheel groove is formed in the side wall of the rotating cavity 11. A transmission shaft 35 is slidably arranged in the axial groove, and the transmission shaft 35 is coaxially arranged with the driving wheel 33; a transmission hole 36 for the transmission shaft 35 to pass through is formed at the center of the driving wheel 33. A number of spiral threads 37 are uniformly distributed on the outer peripheral surface of the transmission shaft 35 along the circumferential direction of the transmission shaft 35, and a number of spiral holes are uniformly distributed on the inner peripheral surface of the transmission hole 36 along the circumferential direction of the transmission hole 36; the number of the spiral threads 37 is the same as that of the spiral holes, and the spiral threads 37 are meshed with the spiral holes. Specifically, when the transmission shaft 35 moves along the axial direction of the outer pipe 1. The spiral threads 37 press against the spiral groove and drive the driving wheel 33 to rotate.

[0037] It should be noted that an embedding groove for embedding the transmission wheel 34 is formed on the outer peripheral surface of the rotating pipe 2. The outer diameter of the embedding groove is larger than the distance from the valve plate 32 to the center of the rotating pipe 2 to prevent gas from overflowing from the gap between the valve plate 32 and the embedding groove.

[0038] Magnetic member 1 38 is fixedly provided at both ends of the shaft groove. Preferably, the cross-section of magnetic member 1 38 is square, and square grooves that can be inserted with magnetic member 1 38 are respectively opened at both ends of the transmission shaft 35.

Metal sheets that can be magnetically adsorbed to magnetic member 1 38 are fixedly provided on the inner walls of the square grooves. Magnetic member 1 38 is an electromagnet. Specifically, by alternately energizing magnetic member 1 38 at both ends of the shaft groove, the transmission shaft 35 is driven to reciprocate along the axial direction of the outer tube 1, thereby driving the driving wheel 33 to rotate clockwise and counterclockwise alternately.

[0039] The intake chamber and the outlet chamber 12 are respectively arranged on both sides of the rotating cavity 11 along the axial direction of the outer tube 1. The cross-sections of the intake chamber and the outlet chamber 12 are both semi-circular; semi-circular pipe grooves 41 are respectively opened at the bottom surfaces of the intake chamber and the outlet chamber 12, and the pipe grooves 41 are arranged along the axial direction of the outer tube 1; air outlet holes 13 communicated with the pipe grooves 41 are opened on the outer side wall of the outer tube 1.

[0040] Specifically, the length of the semi-circular pipe 45 is equivalent to the length of the air outlet hole 13 from the control ring 44. When magnetic member 2 is de-energized and the semi-circular pipe 45 is located in the pipe groove 41, the air flow flows out from the pipe groove 41; the pipe groove 41 is communicated with the condensation chamber, and the air flow enters the condensation chamber through the air outlet hole 13. After magnetic member 2 is energized, the sealing pipe 43 moves towards the direction close to the air outlet hole 13; the semi-circular pipe 45 extends out of the air outlet hole 13, and the end of the sealing pipe 43 blocks the air outlet hole 13.

It should be noted that during the rotation of the rotating pipe 2, after the air inlet hole 1 and the air inlet hole 2 are misaligned, the air outlet hole 2 and the air outlet hole 3 are aligned, for returning the water-containing air flow in the outlet chamber 12 to the intake chamber, or discharging it through the drain pipe.

[0043] Specifically, when the rotating tube 2 rotates, after the first air inlet hole and the second air inlet hole are completely misaligned, the air inlet chamber, the air outlet chamber 12 and the semi-circular chamber 17 are isolated; at the same time, the sealing tube 43 moves towards the first air outlet hole 13, the sealing tube 43 is separated from the plugging groove 46, the second air outlet hole and the third air outlet hole are in alignment, and the air flow returns from the air outlet chamber 12 to the semi-circular chamber 17.

[0044] Specifically, a second control switch for controlling the on / off of the magnetic strip is fixedly provided on the inner wall of the tube sleeve 18. The second control switch includes a second transmission member slidably arranged along the radial direction of the tube sleeve 18 on the inner wall of the tube sleeve 18.

Two insertion slots two that can be inserted with the second transmission member are symmetrically provided on the outer peripheral surface of the outer tube 1. When the second transmission member is inserted into the insertion slot two, the two second switch pieces are in a misaligned state, the second magnetic member is powered off, and the sealing tube 43 is inserted into the plugging groove 46. A chamfer is provided at the top corner position of the second transmission member facing the outside of the second transmission groove for the second transmission member to leave the insertion slot two by abutting against the outer wall of the insertion slot two when the rotating tube 2 rotates. When the second transmission member abuts against the outer peripheral surface of the rotating tube 2, the two second switch pieces are in electrical contact, the second magnetic member is powered on and magnetically adsorbs the sealing tube 43 to move, so that the air duct blocks the first air outlet hole 13.

[0045] A connecting ring 47 is fixed at the end of the rotating tube 2. Two first ventilation holes 42 are symmetrically provided on the connecting ring 47, and electric heating wires are fixedly provided in the two first ventilation holes 42 respectively; the first ventilation holes 42 are arranged in alignment with the first air inlet holes. An annular ring plate 4 is fixedly provided on the inner peripheral surface of the tube sleeve 18, and the arc-shaped wall of the ring plate 4 close to the center of the circle fits with the inner peripheral surface of the rotating tube 2; the ring plate 4 separates the space for storing the water-absorbing medium in the rotating tube 2 from the first ventilation holes 42. A second ventilation hole is provided on the ring plate 4; when the rotating tube 2 stops rotating, the second ventilation hole is arranged in alignment with the first air inlet hole located above the rotating tube 2. The semi-circular chamber 17 rotated to the lower part of the rotating tube 2 is separated from the electric heating wire during the thermal desorption process, which is convenient for the electric heating wire to desorb water without being interfered by the water in the semi-circular chamber 17. An NTC thermistor, a comparator and a relay are provided on the connection circuit of the electric heating wire, and the first magnetic member 38 is connected to the normally closed contact of the relay. After the electric heating wire adsorbs water, its resistance value increases; after the input voltage received by the comparator is lower than the preset voltage threshold, the first magnetic member 38 is controlled to open. The two electric heating wires are respectively electrically connected to a first magnetic member 38.

[0046] Specifically, the heating wire and the NTC thermistor are connected in parallel and then connected to one input terminal of the comparator, and the other input terminal of the comparator is connected to the reference voltage. The output terminal of the comparator is connected to the relay. When the relative humidity rises, the comparator detects that the input voltage is lower than the reference voltage and sends a low level to the relay, and the relay controls the opening of the first magnetic part 38. After the rotating tube 2 rotates, the heating wire rotates below the tube sleeve 18; the heating wire desorbs moisture under the action of the hot air flow, the comparator receives that the input voltage is lower than the reference voltage and sends a high level to the relay, and the relay controls the closing of the first magnetic part 38. It should be noted that when the heating wire below the tube sleeve 18 desorbs moisture, the first magnetic part 38 connected to it is powered off; at the same time, the resistance value of the heating wire above the tube sleeve 18 does not rise to the threshold value, and the transmission shaft 35 is in a static state.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
