Description

Technical Field

[0001] The invention relates to the technical field of dehumidifiers, in particular to a dehumidifier with a filter membrane self-cleaning function. Background Art

[0002] ‌A dehumidifier is a device specially designed to reduce indoor humidity. Its core function is to remove excess moisture from the air, thereby creating a more comfortable and healthy living environment. In humid seasons or regions, excessive humidity may cause mold growth, furniture damage, and human discomfort, and dehumidifiers can effectively solve these problems.

[0003] There are many working principles of dehumidifiers, the most common ones are condensation, adsorption and compression. Condensation dehumidifiers use refrigeration technology to condense water vapor in the air into water droplets and then discharge them; adsorption dehumidifiers use hygroscopic materials such as silica gel, activated carbon and solutions to absorb moisture; compression dehumidifiers separate moisture by compressing and cooling the air.

[0004] Existing dehumidifiers have the following main problems: (1) Dust is not filtered, resulting in blockage inside the dehumidifier; (2) The dehumidification efficiency is poor and it is difficult to meet usage requirements. Summary of the invention

[0005] The object of the present invention is to provide a dehumidifier with a filter membrane self-cleaning function to solve the problems raised in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dehumidifier with a filter membrane self-cleaning function, comprising a solution circulation system and a control system, comprising a shell, wherein a suction port and an exhaust port are respectively arranged on both sides of the shell, a driving motor is arranged at the bottom of the shell, an output shaft of the driving motor is connected to a transmission shaft, a cam is installed on the transmission shaft, a pressurizing box and a liquid storage tank are respectively installed on both sides of the cam, an upper partition is installed below the cam, a lifting plate is installed below the upper partition, a vortex sheet is arranged on the lower side of the lifting plate, a fixing plate is installed on the vortex sheet, a lower partition is installed below the vortex sheet, and a dehumidifying plate is installed below the lower partition; The pressurizing box and the cam cooperate to realize air transportation, the vortex blade removes dust from the air, and the solution circulation system and the dehumidification plate cooperate to dehumidify the air.

[0007] The fixed plate, the upper baffle, the lower baffle and the dehumidifying plate are all mounted on the housing, the fixed plate is provided with a plane thread groove, the vortex blade passes through the plane thread groove and forms a sliding connection; The vortex sheet and the plane thread groove are both distributed in a plane thread line, and a plurality of groups of sliding grooves are arranged on the vortex sheet with adjacent turns, and a sliding plate is slidably installed in the sliding groove, and a filter screen is connected between the two sides of the sliding plate and the lower side of the lifting plate, and a first spring is connected between the middle part of the sliding plate and the lifting plate, and the first spring is located between the filter screens on both sides, and a magnetic material is arranged on the upper side of the sliding plate, and an electromagnet is arranged on the lifting plate opposite to the magnetic material, and the electromagnet is electrically connected to the control system.

[0008] The dust filtering effect of the vortex sheet can be enhanced by the filter. The control system energizes the electromagnet so that the magnetic field generated by the electromagnet and the magnetic field of the sliding plate repel each other. Under the action of the repulsive force, the sliding plate moves downward and stretches the first spring. The sliding plate drives the filter to gradually unfold downward, so that the filter filters the dust flowing in the vortex sheet. Since multiple groups of filter units are arranged on the vortex sheet, and the filter diameters of the filter nets in the multiple groups of filter units become smaller in sequence, different filtering needs can be met.

[0009] A fixed cylinder is arranged on the upper side of the fixed plate, and a sliding cylinder is arranged on the lower side of the lifting plate. The fixed cylinder and the sliding cylinder are respectively located in the middle of the fixed plate and the lifting plate, and a sliding sealing connection is formed between the fixed cylinder and the sliding cylinder. A connecting port is arranged on the circumference of the sliding cylinder, and an output port is arranged on the fixed plate located in the fixed cylinder. The connecting port is connected with the outlet of the vortex sheet, and the bottom of the pressurizing box is connected with the inlet on the upper side of the vortex sheet through a pipeline passing through the upper partition plate; The sliding groove, sliding plate, filter screen, first spring and electromagnet form a filter unit. The filter unit is provided with multiple groups. The multiple groups of filter units are distributed in sequence along the vortex sheet. The diameters of the filter screens in the multiple groups of filter units decrease in sequence.

[0010] The dehumidification plate is provided with multiple groups, and the dehumidification plate is composed of an upper plate body and a lower plate body that are mutually engaged, a semipermeable membrane is provided between the upper plate body and the lower plate body, and an air flow channel and a solution flow channel are respectively provided on opposite sides of the upper plate body and the lower plate body, and the semipermeable membrane only allows water vapor in the air flow channel to pass through and enter the solution flow channel, and the semipermeable membrane adopts a polytetrafluoroethylene porous membrane. The PTFE membrane has excellent chemical resistance and hydrophobicity, and is often used in harsh environments. At the same time, it has a certain selective permeability to water vapor, while other gases and liquids cannot pass through the semipermeable membrane, and the air flow channel and the solution flow channel are both distributed in a leaf vein shape, and the air flow channel and the solution flow channel are in contact with each other and are arranged in parallel; an air inlet and an air outlet are respectively provided at both ends of the upper plate body, and the air inlet and the air outlet are connected to both ends of the air flow channel, and a liquid inlet and a liquid outlet are respectively provided at both ends of the lower plate body, and the liquid inlet and the liquid outlet are connected to both ends of the solution flow channel; The air inlet is connected to the output port through a pipeline passing through the lower partition plate, and the air outlet is connected to the exhaust port through a pipeline.

[0011] The air flow channel and solution flow channel (hereinafter referred to as the main flow channel) distributed in the shape of veins can evenly distribute air and solution (hereinafter referred to as fluid). The fluid enters the main flow channel, then enters several secondary flow channels through the main flow channel, and then enters several small flow channels from several secondary flow channels, so that the fluid is layered and gradually diffuses outward. This kind of vein-shaped design helps to maintain the uniformity of the fluid over a large area, avoiding uneven fluid in the center or edge area, and the vein-shaped design extends the flow path of the fluid, allowing the fluid to stay in the channel longer. That is, the fluid has more time to contact the semipermeable membrane, thereby improving the heat transfer efficiency and significantly improving the uniformity of the membrane surface temperature; the vein-shaped flow channel adopts a segmented flow path (i.e., the main flow channel, secondary flow channel and small flow channel), which can reduce the pressure loss generated by the fluid during the flow process and reduce the energy consumption of the fluid system.

[0012] The pressurizing tank and the liquid storage tank are installed on the upper partition plate, a suction hood is installed on one side of the pressurizing tank, the suction hood is installed on the outer shell, a screen is arranged in the middle of the suction hood, one side of the suction hood is connected with the suction port, and the other side of the suction hood is connected with the pressurizing tank through a pipeline; the pressurizing tank and the liquid storage tank are both hollow inside, and reciprocating plates are slidably installed inside the pressurizing tank and the liquid storage tank, and the reciprocating plates are respectively connected to the pressurizing tank and the liquid storage tank with reset tension springs, and a plurality of protrusions are arranged on the outer side of the cam, and the reciprocating plate abuts against the protrusions on the cam; A plurality of electric plates A are arranged on the inner wall of the suction cover, a plurality of electric plates B are arranged on the inner wall of the vortex blade, and the plurality of electric plates B are located between two adjacent sliding grooves. The electric plates A and B are both electrically connected to the control system.

[0013] The solution circulation system comprises a heater, a regenerator, a cooler and a liquid reservoir, wherein the heater, the regenerator, the cooler and the liquid reservoir are connected in series with each other and mounted on a housing, wherein a solution is stored in the liquid reservoir, and the solution is a water-absorbing liquid, such as a lithium bromide solution, a lithium chloride solution, a calcium chloride solution, or a mixture of two or more of these solutions; the equilibrium water vapor partial pressure of these solutions at a specific concentration is lower than the water vapor partial pressure on the surface of pure water at the same temperature, and therefore, as a desiccant, the solution has strong water absorption and can quickly absorb moisture in the air, thereby achieving an air dehumidification effect; After the high-concentration solution in the liquid reservoir is transported to the liquid inlet, the moisture in the air flow channel passes through the semipermeable membrane and is absorbed by the solution. After the solution absorbs water vapor, the concentration gradually decreases. The low-concentration solution is heated by the heater, and after reaching the temperature required for regeneration, it flows into the regenerator for concentration. After passing through the regenerator, the solution recovers to a high concentration, but the solution temperature is higher at this time and the dehumidification efficiency is lower. The solution then flows through the cooler for cooling and then returns to the liquid reservoir for storage, waiting to enter the solution flow channel through the liquid inlet again for the next round of dehumidification to complete the cycle.

[0014] One side of the liquid storage tank is connected to the outlet of the liquid storage device through a pipeline passing through the shell, and the other side of the liquid storage tank is connected to the liquid inlet after passing through the upper partition, the fixed plate and the lower partition through a pipeline. The liquid outlet is connected to the inlet of the heater through a pipeline passing through the shell.

[0015] The cam is installed on the transmission shaft, and both ends of the transmission shaft are rotatably installed on the outer shell. The transmission shaft passes through the upper partition, the lifting plate, the sliding cylinder, the fixed plate and the lower partition. The transmission shaft forms a seal with the sliding cylinder and the lifting plate. The upper partition, the fixed plate and the lower partition are rotatably connected to the transmission shaft through bearings.

[0016] The air flow channel and the solution flow channel are respectively connected to a plurality of secondary pulse flow channels, a plurality of the secondary pulse flow channels are respectively connected to a plurality of small pulse flow channels, and a plurality of the small pulse flow channels are connected to each other; A plurality of flow blocks are arranged in the solution flow channel and the air flow channel. The flow blocks are in the shape of cuttlefish fins. The flow blocks can enhance the disturbance of the air in the flow channel and play an effect of enhancing mass transfer.

[0017] A guide column is connected between the outer side of the lifting plate and the fixed plate. The guide column is located outside the swirl plate. The guide column is a telescopic structure. A second spring is connected between the lifting plate and the fixed plate. The second spring is sleeved on the guide column and is electrically connected to the control system.

[0018] A discharge plate is provided on the shell directly facing the exhaust port, and the discharge plate and the shell are snap-fitted, and the output port is also connected to an ash discharge port through a pipeline, and the ash discharge port is provided on the shell; The pipeline is installed with a solenoid valve, a flow meter and a pressure sensor, and the solenoid valve, the flow meter and the pressure sensor are electrically connected to the control system. The housing is provided with a control panel, and the control system is arranged in the control panel.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The design of the leaf vein flow channel ensures the uniformity of air or solution and improves the uniformity of membrane surface temperature. The air flow channel and solution flow channel (hereinafter referred to as the main flow channel) with leaf vein shape distribution can evenly distribute air and solution (hereinafter referred to as fluid). The fluid enters the main flow channel, then enters several secondary flow channels through the main flow channel, and then enters several small flow channels from several secondary flow channels, so that the fluid is layered and gradually diffuses outward. This leaf vein shape design helps to maintain the uniformity of the fluid over a larger area, avoiding uneven fluid in the center or edge area, and the leaf vein shape design extends the flow path of the fluid, allowing the fluid to stay in the channel longer. That is, the fluid has more time to contact the semipermeable membrane, thereby improving the heat transfer efficiency, significantly improving the uniformity of the membrane surface temperature, and enhancing the dehumidification effect.

[0020] 2. Dust the air entering the dehumidifier to prevent dust from clogging the dehumidifier. Smaller dust particles and air continue to flow in the vortex blade. Since the flow direction of dust and air in the vortex blade is constantly changing, and dust and air have different inertia forces, dust hits the vortex blade and loses kinetic energy, while air continues to flow to the outlet of the vortex blade, achieving separation of small dust particles and air, and negatively charged dust is attracted by the electric plate B, so that the dust is deposited on the electric plate B. Through the setting of the vortex blade and the coordination of the electric plates A and B, dust is deposited in the vortex blade, and air is discharged from the outlet of the vortex blade, ensuring the cleanliness of the air for subsequent dehumidification treatment.

[0021] 3. Extraction and delivery of air and solution, more compact structure. Through the continuous rotation of the cam, the extraction and delivery of air and solution are realized, and the air is delivered to the air flow channel after dust removal, while the solution is delivered to the solution flow channel. The dehumidification of air is achieved through the coordination of the solution flow channel, air flow channel and semi-permeable membrane, with a more compact structure and stronger practicality.

[0031] When the dehumidifier works for the set time, it will automatically enter the cleaning mode. The control system first continuously powers on and off the electromagnet 243. After the electromagnet 243 is powered on, it attracts the magnetic material on the sliding plate 241. Under the action of the attraction, the sliding plate 241 moves upward and compresses the first spring. The sliding plate 241 also drives the filter 242 to fold and shrink upward. After that, the electromagnet 243 is powered off, and the first spring is released. The first spring pushes the sliding plate 241 to move downward. The sliding plate 241 drives the filter 242 to expand and lengthen downward. The sliding plate 241 is continuously driven up and down by the electromagnet 243, so that the filter 242 vibrates. The dust on the filter 242 falls downward onto the fixed plate 111 and the vortex sheet 24 under the action of vibration, so that the filter 242 is cleaned. After the filter 242 is cleaned for a set time, the control system drives the sliding plate 241 to move upward through the electromagnet 243, and the sliding plate 241 drives the filter 242 to fold upward, so that the cleaned filter 242 does not filter the air, so as to facilitate the subsequent cleaning of the vortex blade 24; After the filter screen 242 is wrinkled upward, the electromagnet 243 feeds back the size of the suction force to the control system, and the control system continuously energizes and deenergizes the second spring 231 and deenergizes the electric plate A13 and the electric plate B131. After the second spring 231 is energized, each turn generates a magnetic field that attracts each other, and the magnetic field compresses the second spring 231, so that the second spring 231 is shortened as a whole, and the second spring 231 pulls the lifting plate 23 to move downward, and the lifting plate 23 drives the vortex sheet 24 to move downward from the plane thread groove. After that, the second spring 231 is deenergized, and the second spring 231 gradually becomes longer under the action of its own elastic force, and the second spring 231 pushes the lifting plate 23 to move upward, and the lifting plate 23 drives the vortex sheet 24 to move upward in the plane thread groove. The control system continuously energizes and deenergizes the second spring 231, so that the vortex sheet 24 vibrates rapidly up and down, and the dust on the vortex sheet 24 falls due to the vibration, and the dust is deposited on the fixed plate 111; While the vortex sheet 24 is driven to vibrate by the second spring 231, the control system controls the drive motor 2 to drive the cam 22 to rotate, and closes the solenoid valve in the pipe between the output port 116 and the air inlet 253 and opens the solenoid valve in the pipe between the output port 116 and the ash discharge port 14. The protrusion on the cam 22 pushes the reciprocating plate 31 in the pressurizing box 3 to move, so that the air in the pressurizing box 3 is transported to the inlet on the upper side of the vortex sheet 24 through the pipe. The pressurized air continues to flow in the vortex sheet 24. The pressurized air blows the dust in the vortex sheet 24 to the connecting port 115, the output port 116, the pipe and the ash discharge port 14 in turn, and is discharged from the ash discharge port 14, thereby cleaning the inside of the vortex sheet 24.

[0032] Working principle: Press the start button on the control panel 1, the dehumidifier starts, the drive motor 2 drives the transmission shaft 21 to rotate, the transmission shaft 21 drives the cam 22 to rotate, and the encoder inside the drive motor 2 feeds back the rotation data of the cam 22 to the control system; When the protrusion on the cam 22 is not close to the reciprocating plate 31 in the pressurizing box 3, the control system closes the solenoid valve in the pipeline between the pressurizing box 3 and the swirl plate 24 and opens the solenoid valve in the pipeline between the pressurizing box 3 and the suction cover 301, and the reset tension spring is released. The reset tension spring pushes the reciprocating plate 31 to move inward (from the inside of the pressurizing box 3 to the outside), so that the chamber between the reciprocating plate 31 (the reciprocating plate 31 in the pressurizing box 3) and the pressurizing box 3 becomes larger, and the external air enters the suction cover 301 through the suction port 12. After the external air is initially filtered by the screen, large particles of dust are deposited on the screen, and air and small particles of dust enter the pressurizing box 3 through the suction cover 301, thereby realizing the extraction and filtration of external air; When external air enters the suction cover 301, the flow meter in the connection pipe of the suction cover 301 feeds back data to the control system, and the control system connects the electric plate A13 in the suction cover 301 to the negative pole of the power supply and the electric plate B131 in the vortex sheet 24 to the positive pole of the power supply, discharges the air through the electric plate A13 to form a corona, and ionizes the air into equal amounts of positive and negative ions, the positive ions are quickly absorbed by the electric plate A13, and the negative ions are repelled by the electric plate A13, and the negative ions are retained in the air, so that the dust in the air is negatively charged after contacting with the negative ions; As the cam 22 continues to rotate, when the protrusion on the cam 22 approaches the reciprocating plate 31 in the pressurizing box 3, the control system opens the solenoid valve in the pipeline between the pressurizing box 3 and the vortex blade 24, closes the solenoid valve in the pipeline between the pressurizing box 3 and the suction cover 301, and opens the solenoid valve in the pipeline between the output port 116 and the air inlet 253. The protrusion on the cam 22 pushes the reciprocating plate 31 (the reciprocating plate 31 in the pressurizing box 3) to move inward and compress the reset tension spring. The reciprocating plate 31 pressurizes the air in the pressurizing box 3 and transports it to the inlet on the upper side of the vortex blade 24 (located on the outside of the vortex blade 24) through the pipeline. Smaller dust particles and air are kept in the vortex blade 24. The dust and air continue to flow. Since the flow directions of the dust and air in the vortex sheet 24 are constantly changing, and the dust and air have different inertia forces, the dust hits the inner wall of the vortex sheet 24 and loses kinetic energy, while the air continues to flow to the outlet of the vortex sheet 24 (located in the middle of the vortex sheet 24), so that the small particles of dust and air are separated, and the negatively charged dust is attracted by the electric plate B131, so that the dust is deposited on the electric plate B131. Through the setting of the vortex sheet 24 and the cooperation of the electric plate A13 and the electric plate B131, the dust is deposited in the vortex sheet 24, and the air is discharged from the outlet of the vortex sheet 24, so as to ensure the cleanliness of the air and facilitate the subsequent dehumidification treatment.

[0033] As the air continues to be discharged from the outlet of the vortex blade 24, the air enters the chamber between the sliding cylinder 112 and the fixed cylinder 114 through the connecting port 115, and flows from the chamber, the output port 116 and the pipeline to the air inlet 253, and then enters the dehumidification plate 25 through the air inlet 253, thereby realizing air transportation.

[0034] The cam 22 continues to rotate, and the protrusion on the cam 22 moves away from the reciprocating plate 31 in the pressurizing tank 3 and then approaches the reciprocating plate 31 in the liquid storage tank 4. The encoder in the driving motor 2 feeds back the rotation data of the cam 22 to the control system. The control system transports the solution to the liquid storage tank 4 through the solution circulation system, and opens the solenoid valve in the pipeline between the liquid storage tank 4 and the liquid inlet 255. After that, the protrusion on the cam 22 pushes the reciprocating plate 31 (the reciprocating plate 31 in the liquid storage tank 4) to move outward, and the solution in the liquid storage tank 4 is pressurized and transported to the liquid inlet 255 through the pipeline, thereby realizing the transportation of the solution.

[0035] When the solution and air enter the dehumidification plate 25 through the air inlet 253 and the liquid inlet 255 respectively, the air enters the air flow channel 251 of the upper plate body through the air inlet 253, and the solution enters the solution flow channel 252 in the lower plate body through the liquid inlet 255. The air and the solution diffuse and flow outward along the leaf vein-shaped flow channels in the air flow channel 251 and the solution flow channel 252 respectively to improve the mass transfer efficiency. The moisture in the air passes through the semipermeable membrane and is absorbed by the solution. The dehumidified air is discharged from the dehumidifier through the air outlet 254 and the exhaust port 121 to achieve air dehumidification treatment, and the solution is transported from the liquid outlet 256 and the pipeline to the solution circulation system to achieve further treatment of the solution for reuse.
