Description

Technical Field

[0001] This application relates to the technical field of air dehumidification, and particularly to a dehumidifier. Background Art

[0002] Dehumidifiers are generally divided into two categories: household dehumidifiers and industrial dehumidifiers. Conventional dehumidifiers include a heat exchanger, a fan, a water tank, a casing, and a controller. Its working principle is that the fan sucks in humid air into the machine and passes it through the heat exchanger. At this time, the water molecules in the air condense into water droplets, and then the processed dry air is discharged outside the machine. Such a cycle is carried out to keep the air at an appropriate humidity.

[0003] Among them, some components such as the heat exchanger and the fan are scattered on the casing. When installing, workers need to reach their hands inside the outer casing and install the components one by one at specific positions, and ensure a good cooperation relationship between them. Therefore, it is rather inconvenient in the production and assembly of dehumidifiers. Summary of the Invention

[0004] In order to facilitate the production and assembly of dehumidifiers, this application provides a dehumidifier.

[0005] A dehumidifier provided by this application adopts the following technical solutions:

[0006] A dehumidifier includes:

[0007] A casing provided with a cavity, an air inlet, and an air outlet communicating with the cavity;

[0008] A dehumidifying device installed in the cavity. The dehumidifying device includes a wind guide shell communicating with both the air inlet and the air outlet, heat dissipation fins arranged inside the wind guide shell, an evaporation sheet arranged on the side of the wind guide shell close to the air inlet and mounted on the heat dissipation fins, a refrigeration sheet clamped between the evaporation sheet and the heat dissipation fins, a fan arranged on the side of the wind guide shell facing away from the evaporation sheet, and a power supply board mounted on one side of the wind guide shell. A photocatalyst net is arranged in the wind guide shell, and the photocatalyst net is located at the air outlet. A UV lamp board for irradiating the photocatalyst net is further arranged on the wind guide shell, and / or a negative ion generator is arranged on the wind guide shell, and the negative ion generator is located at the air outlet;

[0009] A water tank located below the dehumidifying device and mounted on the casing for storing condensed water.

[0010] By adopting the above technical solutions, the heat sink, evaporation sheet, refrigeration sheet, fan and power board are all installed on the air guide housing to form a module. During production and assembly, only the whole module needs to be installed on the outer shell, thus making the assembly of the dehumidifier relatively convenient. The water tank is used to store the condensed water on the evaporation sheet. The heat sink is installed inside the air guide housing. The evaporation sheet and the fan are respectively arranged on opposite sides of the air guide housing. The power board is arranged on the other side of the air guide housing, reasonably utilizing the space of the air guide housing, making the overall structure relatively compact and the space occupancy rate relatively low, thereby reducing the overall space occupancy rate of the dehumidifier.

[0011] The setting of the photocatalyst net can sterilize the air discharged from the dehumidifier. The UV lamp board can strengthen the illumination of the photocatalyst net and improve the sterilization effect of the photocatalyst net. At the same time, the negative ion generator purifies and deodorizes the discharged air. The photocatalyst net and the negative ion generator are both installed on the air guide housing to form a module with the evaporation sheet, etc., further improving the convenience during the production and assembly of the dehumidifier.

[0012] Optionally, the outer shell includes an upper shell and a base. The dehumidification device is installed inside the upper shell. Pillars connected to the upper shell are provided on the base. The water tank is located in the gap between the upper shell and the base and is installed on the base. A magnetic float is arranged inside the water tank, and a magnetic induction switch is arranged on the pillar.

[0013] By adopting the above technical solutions, the whole dehumidification device module is installed on the upper shell, then the upper shell is installed on the pillars, and finally the water tank is installed on the base, reducing the overall assembly steps. When the magnetic float rises to a certain height along with the water level in the water tank and disconnects from the magnetic induction switch, the whole dehumidification device stops running, thereby reducing the risk of water overflow caused by the dehumidification device still running after the water tank is full.

[0014] Optionally, the dehumidifier further includes a dust isolation cover arranged on the side of the evaporation sheet close to the air inlet. A long strip groove is opened on the side of the dust isolation cover close to the air inlet. The long strip groove penetrates through the dust isolation cover, and a dust isolation net is installed in the long strip groove. A plurality of long strip grooves are opened, and the plurality of long strip grooves are arranged at intervals. A plurality of dust isolation nets are also provided. The number of the dust isolation nets is the same as that of the long strip grooves and corresponds one by one. A dust collection box for collecting the dust on the dust isolation net is arranged on the outer shell.

[0015] By adopting the above technical solution, the setting of the dust isolation cover reduces the risk that dust in the air adheres to the evaporation sheet, thereby increasing the power consumption of the evaporation sheet and reducing the condensation effect of the evaporation sheet. At the same time, the dust isolation net is arranged in the long strip groove to form a groove. When cleaning the dust, the groove wall of the long strip groove will play a role in blocking, reducing the risk of dust scattering everywhere when cleaning the dust. In addition, when cleaning the dust, the long strip groove also plays a role in positioning, that is, only need to use a tool to brush the dust in the long strip groove into the dust collection box for collection. Compared with cleaning a whole large dust isolation net, when the dust is cleaned, the dust will scatter to the position after cleaning. The above structure improves the efficiency and convenience when cleaning the dust.

[0016] Optionally, the dehumidifier further includes a dust removal mechanism, and the dust removal mechanism includes a rack slidably mounted on the dust isolation cover and a dust removal brush arranged on the rack for cleaning the dust on the dust isolation net.

[0017] By adopting the above technical solution, the dust removal brush corresponds to the dust isolation net. When cleaning, only need to move the rack to move the dust removal brush, then the corresponding dust isolation net can be cleaned, further improving the convenience when cleaning the dust.

[0018] Optionally, a sliding groove is vertically opened on one side of the dust isolation cover close to the long strip groove, the sliding groove is communicated with a plurality of the long strip grooves, and a water baffle for blocking or opening the plurality of long strip grooves is slidably mounted in the sliding groove. The water baffle is located on the side of the dust isolation net close to the evaporation sheet;

[0019] A micro motor is arranged on the water baffle, a gear meshing with the rack is arranged on the micro motor, a gantry photoelectric switch is arranged on the dust isolation cover, and a light blocking plate for blocking or connecting the light of the gantry photoelectric switch is arranged on the water baffle.

[0020] By adopting the above technical solution, when the dust isolation net needs to be cleaned, push the water baffle to move it in the sliding groove, thereby blocking the long strip groove, reducing the risk of dust and water droplets during cleaning adhering to the evaporation sheet.

[0021] The micro motor moves together with the water baffle. When moving the water baffle to block the opening of the long strip groove, the light blocking plate blocks the light between the gantry photoelectric switches. After the controller receives the signal, it controls the micro motor to operate, and then the rack drives the dust removal brush to move to brush away the dust. When the water baffle does not block the long strip groove, the light blocking plate does not block the light emitted by the gantry photoelectric switch, and the micro motor will not operate, further reducing the risk of dust and water droplets during cleaning adhering to the evaporation sheet.

[0022] Optionally, the dehumidifier further includes a flushing mechanism for flushing the dust separation net. The flushing mechanism includes a micro water pump, a water inlet pipe, a water outlet pipe, and a spray head disposed on the water outlet pipe for flushing the dust separation net.

[0023] A water receiving box for receiving the condensed water on the evaporation sheet is disposed on the outer shell. A water collecting cavity and a sewage cavity are arranged inside the water tank. The water collecting cavity is not communicated with the sewage cavity. The water collecting cavity is communicated with the water receiving box. The sewage cavity is communicated with the dust collecting box. One end of the water inlet pipe is connected to the micro water pump and the other end is located inside the water collecting cavity. The water outlet pipe is slidably installed on the dust separation cover.

[0024] By adopting the above technical solution, when cleaning the dust separation net, the micro water pump pumps out the condensed water in the water collecting cavity and flushes it through the spray head. On the one hand, it is more convenient to clean the dust separation net without connecting an external water source. On the other hand, the condensed water itself is the humid moisture in the air, and the waste of water resources is reduced by pumping and flushing the condensed water. The sewage for flushing the dust separation cover will flow into the sewage cavity through the dust collecting box for collection without mixing with the water in the water collecting cavity, making the water for cleaning the dust separation net relatively clean, thereby improving the cleaning effect of the dust separation net.

[0025] Optionally, the dehumidifier further includes a water removing mechanism. The water removing mechanism includes a water absorbing cotton disposed on the rack and a pressing plate disposed on the dust separation cover for pressing the water absorbing cotton. The pressing plate is located on the side of the dust separation cover close to the dust collecting box.

[0026] By adopting the above technical solution, the water absorbing cotton will absorb the water droplets on the dust separation net into itself when moving. When the water absorbing cotton moves to the lowest end, a large amount of water is stored in the water absorbing cotton. At this time, when the water absorbing cotton continues to move, the water stored in itself will be squeezed out under the action of the pressing plate and fall into the dust collecting box, thereby improving the water absorption of the water absorbing cotton for the next water absorption and reducing the risk of the water droplets remaining on the dust separation net combining with dust to form mud.

[0027] Optionally, an arc-shaped protrusion is disposed on the side of the pressing plate close to the air inlet, and a guide plate is disposed on the side of the pressing plate close to the dust collecting box. Flow guide grooves are disposed on both the arc-shaped protrusion and the guide plate.

[0028] By adopting the above technical solution, when the water absorbing cotton moves to the position of the arc-shaped protrusion, it will be subjected to a squeezing force under the action of the arc-shaped protrusion, thereby squeezing out the absorbed water. At the same time, when the water absorbing cotton rises, it will cooperate with the arc-shaped protrusion again to be subjected to a squeezing force, further squeezing out the absorbed water, and the water absorbing cotton will absorb the remaining water droplets on the dust separation net again during the rising process after squeezing out the water, further reducing the risk of water droplets remaining on the dust removal net.

[0029] The sewage used to flush the dust screen will flow down the dust screen under the action of gravity. Due to the setting of the arc protrusion, the sewage will splash when it falls on the top of the arc protrusion. The setting of the guide plate and the guide groove can guide the sewage into the dust collecting box, reducing the risk of sewage splashing.

[0030] Optionally, the spray head is located above the dust removal brush, the absorbent cotton is located above the spray head, and the water outlet pipe and the absorbent cotton are both installed on the rack.

[0031] By adopting the above technical solution, as the rack moves, the dust removal brush, the spray head and the absorbent cotton will all move synchronously. Compared with the dust removal brush, the absorbent cotton and the spray head each having its own driving parts, only one driving part is needed, which reduces the cost and the driving source. At the same time, when cleaning, the dust removal brush cleans while the spray head rinses while the absorbent cotton removes the water droplets on the dust screen. Compared with the three running separately, the cleaning efficiency is improved.

[0032] Optionally, a water absorbing strip is provided on the groove wall of the long groove, and the water absorbing strip is attached to a side of the water baffle plate close to the dust screen.

[0033] By adopting the above technical solution, when the sprinkler head flushes the dust screen, water droplets will splash onto the water baffle plate. When the water baffle plate is moved so that it does not block the long groove, the water splashed on the water baffle plate will be absorbed on the water absorption strip. During dehumidification, the fan will suck air, and the wind will pass through the water absorption strip and then dry the water absorption strip.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] The heat sink, evaporator, cooling fin, fan and power board are all installed on the air guide shell to form a module. During production and assembly, it is only necessary to install the entire module on the shell, which makes the assembly of the dehumidifier more convenient.

[0036] The setting of the dust cover reduces the risk of dust in the air adhering to the evaporating plate, thereby increasing the power consumption of the evaporating plate and reducing the condensation effect of the evaporating plate. The dust removal mechanism can first sweep the dust on the dust cover into the dust collection box; then the flushing mechanism will flush the dust cover to further flush away the dust, and the sewage with dust will flow into the dust collection box and into the sewage cavity; the water removal mechanism will absorb and remove the water droplets remaining on the dust cover, thereby reducing the risk of dust in the air mixing with water droplets to become mud when used next time;

[0037] When the dust screen needs to be cleaned, press the moving button to move the water baffle to cover the opening of the long groove, reducing the risk of dust and water droplets adhering to the evaporation plate during cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following further describes the present application in detail with reference to Figure 1-8 the accompanying drawings.

[0048] An embodiment of the present application discloses a dehumidifier. Refer to Figure 1 and Figure 2 , the dehumidifier includes an outer shell 1, a dehumidifying device 2 and a water tank 3. The dehumidifying device 2 is installed in the outer shell 1 as a module, and the water tank 3 is located below the dehumidifying device 2 and installed on the outer shell 1 to receive the condensate in the dehumidifying device 2.

[0049] Refer to Figure 2 , the outer shell 1 includes an upper shell 11 and a base 12. There is a cavity in the upper shell 11, and the dehumidifying device 2 is installed in the cavity. A support pillar 13 is integrally formed on one side of the base 12 close to the upper shell 11, and the support pillar 13 is installed on the upper shell 11 through bolts. A gap for installing the water tank 3 is formed between the base 12 and the upper shell 11 through the support pillar 13. The water tank 3 is located in the gap and is clamped and limited on the base 12. Specifically, a buckle is integrally formed on the base 12, a clamping groove is formed at the bottom of the water tank 3, and after the water tank 3 is inserted into the gap, the buckle is clamped in the clamping groove to limit the water tank 3.

[0050] On one side of the water tank 3 near the support column 13, a guide rail 31 is integrally formed in the vertical direction. A magnetic float 32 is arranged on the guide rail 31. The moving direction of the magnetic float 32 is consistent with the extending direction of the guide rail 31. A magnet is installed on the side of the magnetic float 32 close to the support column 13. An installation groove is formed on the side of the support column 13 away from the water tank 3. A magnetic induction switch 131 cooperating with the magnetic float 32 is installed at the bottom of the installation groove through bolts, and a cover plate is installed at the notch of the installation groove. Among them, the magnetic float 32 floats as the water level in the water tank 3 rises, and then loses the coupling relationship with the magnetic induction switch 131. At this time, the dehumidifying device 2 stops working, and no more condensed water enters the water tank 3.

[0051] Refer to Figure 1 And Figure 2 , the upper shell 11 includes a water receiving chassis 14, a front shell 15, a rear shell 16 and a top cover 17. After the four are assembled by bolts, a cavity for installing the dehumidifying device 2 is formed, and the support column 13 is installed on the water receiving chassis 14. An air inlet 161 is formed on the side of the rear shell 16 away from the front shell 15, and the air inlet 161 is communicated with the cavity. An air outlet 171 is formed on the top cover 17, and the air outlet 171 is also communicated with the cavity. At the same time, a handle is rotatably installed on the top cover 17. When moving the dehumidifier, the handle can be lifted.

[0052] Refer to Figure 2 And Figure 3 , the dehumidifying device 2 includes a wind guide shell 21, a heat sink 22, an evaporation sheet 23, a refrigeration sheet 24, a fan 25 and a power supply board 26. The heat sink 22 is installed inside the wind guide shell 21 through bolts, and the air inlet 161 is communicated with the inside of the wind guide shell 21. The evaporation sheet 23 is located on the side of the wind guide shell 21 close to the air inlet 161 and is installed on the heat sink 22 through bolts. The refrigeration sheet 24 is clamped between the heat sink 22 and the evaporation sheet 23. The heat-absorbing side of the refrigeration sheet 24 is attached to the evaporation sheet 23, and the heat-dissipating side of the refrigeration sheet 24 is attached to the heat sink 22, so that the temperature near the evaporator is lower than the indoor temperature, which is convenient for condensing the moisture in the air into water droplets and dripping into the water receiving chassis 14 and entering the water tank 3. At the same time, the heat sink 22 disperses the heat dissipated by the refrigeration sheet 24, thereby drying the air entering the wind guide shell 21 and discharging it from the air outlet 171. The fan 25 is installed on the side of the wind guide shell 21 away from the evaporation sheet 23 through bolts to suck air into the wind guide shell 21. Among them, in this embodiment, the fan 25 is preferably a nine-blade DC fan 25, so that the noise generated during operation is small. The power supply board 26 is installed on the side of the wind guide shell 21 perpendicular to the side where the fan 25 is installed through bolts to supply power to the fan 25 and the refrigeration sheet 24.

[0053] One side of the air guide housing 21 close to the air outlet 171 is provided with an opening communicating with the inside of the air guide housing 21. One side of the air guide housing 21 close to the air inlet 161 is provided with an air flow inlet 211 that communicates the inside of the air guide housing 21 with the cavity inside the upper housing 11. One side of the air guide housing 21 close to the fan 25 is provided with an air flow suction port 212 communicating with the inside of the air guide housing 21. When the fan 25 operates, the air outside the upper housing 11 is sucked into the inside of the upper housing 11 from the air inlet 161. After the air is condensed by the evaporation sheet 23, it enters the inside of the air guide housing 21 from the air flow inlet 211. At the same time, the heat on the heat sink 22 will dry the air, and the dried air will rise and be discharged from the air outlet 171.

[0054] Refer to Figure 2 and Figure 3 , an air purification net 213 is installed in an interference fit at the opening of the air guide housing 21 close to the air outlet 171. The air purification net 213 is located above the heat sink 22, so as to sterilize the discharged air. One side of the air guide housing 21 where the fan 25 is installed is bolted with a UV lamp board 214, and the lamp beads on the UV lamp board 214 pass through the air guide housing 21 and are located inside the air guide housing 21. There is a placement gap for the lamp beads on the UV lamp board 214 between the air purification net 213 and the heat sink 22. By lighting the UV lamp board 214, light is provided for the air purification net 213, thereby improving the sterilization effect of the air purification net 213.

[0055] One side of the air guide housing 21 where the evaporation sheet 23 is installed is bolted with a negative ion generator 215. The negative ion generator 215 is located above the evaporation sheet 23, and the probe of the negative ion generator 215 is located between the air purification net 213 and the heat sink 22, so as to purify and deodorize the discharged air. Among them, only the air purification net 213 and the UV lamp board 214 can be installed on the air guide housing 21, or only the negative ion generator 215 can be installed, or both the air purification net 213 and the UV lamp board 214 and the negative ion generator 215 can be installed. In this embodiment, it is preferred to install both the air purification net 213 and the UV lamp board 214 and the negative ion generator 215.

[0056] Refer to Figure 3 and Figure 4 , a water receiving box 141 is integrally formed on the top of the water receiving chassis 14. Taking the water receiving box 141 as a rectangular box, the top of the water receiving box 141 is open, and the water receiving box 141 is located below the evaporation sheet 23 so that the condensed water on the evaporation sheet 23 can fall into the water receiving box 141. A condensed water outlet 142 communicating with the water tank 3 is opened at the bottom of the water receiving box 141, and the condensed water outlet 142 is located on one side in the length direction of the water receiving box 141.

[0057] Refer to Figure 3 , Figure 4 and Figure 5, the dehumidifier further includes a dust isolation cover 4, a dust removal mechanism 5, a flushing mechanism 6, and a water removal mechanism 7. The dust isolation cover 4 is located on the side of the evaporation fin 23 close to the air inlet 161 and covers the evaporation fin 23, thereby reducing the risk of dust in the air adhering to the evaporation fin 23. The dust removal mechanism 5 is slidably mounted on the dust isolation cover 4 to clean the dust on the dust isolation cover 4. The flushing mechanism 6 is also slidably mounted on the dust isolation cover 4 to flush the dust isolation cover 4 that has been cleaned by the dust removal mechanism 5. The water removal mechanism 7 is likewise slidably mounted on the dust isolation cover 4 to absorb and remove the water droplets on the dust isolation cover 4 that has been flushed by the flushing mechanism 6. Among them, the dust removal mechanism 5, the flushing mechanism 6, and the water removal mechanism 7 all slide vertically. A dust collection box 143 is integrally formed on the water receiving chassis 14. The dust cleaned from the dust isolation cover 4 and the sewage for flushing the dust isolation cover 4 will fall into the dust collection box 143 and flow into the water tank 3 from the dust collection box 143.

[0058] Referring to Figure 3 With Figure 6 , the dust isolation cover 4 is installed on the air guide housing 21 by bolts, and a receiving cavity is provided on the side of the dust isolation cover 4 close to the evaporation fin 23, and the evaporation fin 23 is located in the receiving cavity. A long slot 41 penetrating the dust isolation cover 4 is provided on the side of the dust isolation cover 4 close to the air inlet 161, and the long slot 41 extends vertically. A dust isolation net 42 is installed in the long slot 41. The dust isolation net 42 is adapted to the long slot 41, and the dust isolation net 42 is glued to the wall of the long slot 41 by glue. Air can enter the interior of the air guide housing 21 through the dust isolation net 42, but the dust in the air will adhere to the dust isolation net 42. There are multiple long slots 41, and the multiple long slots 41 are arranged at intervals in the horizontal direction. The dust isolation net 42 is also provided with multiple dust isolation nets 42. The number of the dust isolation nets 42 is the same as the number of the long slots 41 and they correspond one by one. A condensate opening is provided at the bottom of the dust isolation cover 4 for the water droplets on the evaporation fin 23 to drip into the water tank 3.

[0059] Among them, a sliding slot 43 penetrating the dust isolation cover 4 is provided in the horizontal direction perpendicular to the direction in which the long slot 41 is opened on the dust isolation cover 4. A water baffle 44 is slidably mounted in the sliding slot 43. The water baffle 44 is located on the side of the dust isolation net 42 close to the evaporation fin 23, and both opposite ends of the water baffle 44 along the opening direction of the sliding slot 43 protrude from the sliding slot 43. A square hole 441 penetrating the water baffle 44 in the horizontal direction is provided on the water baffle 44. The square hole 441 matches and communicates with the long slot 41. Since there are multiple long slots 41, there are also multiple square holes 441, and the multiple square holes 441 correspond and match the multiple long slots 41. By moving the water baffle 44, the part between two adjacent square holes 441 just blocks the long slot 41, thereby reducing the risk that dust and water will adhere to the evaporation fin 23 during cleaning.

[0060] Referring to Figure 6, Specifically, a moving button 45 is integrally formed on one side of the water baffle 44 protruding from the sliding groove 43. The moving button 45 passes through the rear shell 16 and is exposed outside the rear shell 16. Pressing the moving button 45 can cause the water baffle 44 to slide, thereby blocking the long slot 41. A spring post is fixed to the side of the water baffle 44 away from the moving button 45 by strong glue, and a return spring 46 is sleeved on the spring post. A spring seat is integrally formed on the inner wall of the rear shell 16, and a spring groove is formed on the spring seat. The end of the return spring 46 away from the spring post is inserted into the spring groove. A limiting ring is integrally provided on the part of the moving button 45 located in the rear shell 16. Normally, the water baffle 44 does not block the long slot 41 under the action of the return spring 46, that is, the square hole 441 is communicated with the long slot 41 to allow air to pass through normally. At this time, the abutting ring abuts against the rear shell 16.

[0061] Among them, a water-absorbing strip 411 is glued to the groove wall on the side of the long slot 41 close to the moving button 45. The water-absorbing strip 411 is located on the side of the water baffle 44 close to the dust-proof net 42, and the water-absorbing strip 411 abuts against the water baffle 44. Therefore, when the water baffle 44 moves, the water droplets on the water baffle 44 can be absorbed by the water-absorbing strip 411.

[0062] Refer to Figure 2 And Figure 6 , A locking pull button 47 is slidably provided on the side of the rear shell 16 away from the front shell 15. The locking pull button 47 includes a locking rod 471, a spring plate 472, and a pressure spring 473. A sliding hole for the locking rod 471 to pass through is formed in the rear shell 16. After the locking rod 471 passes through the sliding hole, part of it is located outside the rear shell 16 and part of it is located inside the rear shell 16. The spring plate 472 is sleeved on the part of the locking rod 471 located inside the rear shell 16 and is integrally formed with the locking rod 471. The pressure spring 473 is sleeved on the locking rod 471, and the pressure spring 473 is located inside the rear shell 16. One end of the pressure spring 473 abuts against the spring plate 472, and the other end abuts against the rear shell 16. The end of the locking rod 471 located inside the rear shell 16 abuts against the water baffle 44. The sliding direction of the locking rod 471 is perpendicular to the sliding direction of the water baffle 44. A locking groove 442 is formed on the side of the water baffle 44 close to the air inlet 161. After the baffle slides, the locking rod 471 is inserted into the locking groove 442 under the action of the pressure spring 473. At this time, the water baffle 44 blocks the long slot 41. When unlocking is required, pull the part of the locking rod 471 located outside the rear shell 16 by hand to pull the locking rod 471 out of the locking groove 442. At this time, the water baffle 44 automatically resets to the position before sliding under the action of the return spring 46.

[0063] Refer to Figure 5 And Figure 6, on the side of the dust-proof cover 4 facing away from the movement button 45, a portal photoelectric switch 8 is installed. On the side of the water baffle 44 close to the portal photoelectric switch 8, a light-blocking plate 443 is integrally formed. When the water baffle 44 blocks the long slot 41, the light-blocking plate 443 is inserted into the portal photoelectric switch 8 to block the light. At this time, the controller receives the signal and controls the dust removal mechanism 5, the flushing mechanism 6, and the water removal mechanism 7 to start operating to clean the dust on the dust-proof net 42.

[0064] Refer to Figure 7 , the dust removal mechanism 5 includes a rack 51, a first mounting rod 52, and a dust removal brush 53. The rack 51 is slidably mounted on the dust-proof cover 4. The first mounting rod 52 is located on the side of the dust-proof net 42 close to the air inlet 161, and the first mounting rod 52 is integrally formed with the rack 51. A dust removal brush 53 for cleaning the dust on the dust-proof net 42 is fixedly mounted on the side of the first mounting rod 52 close to the dust-proof net 42. Since there are multiple dust-proof nets 42, there are also multiple dust removal brushes 53, and the multiple dust removal brushes 53 correspond to the multiple dust-proof nets 42 one by one.

[0065] Refer to Figure 6 With Figure 7 , on the side of the top of the dust-proof cover 4 close to the portal photoelectric switch 8, a dovetail groove 48 is opened. The dovetail groove 48 runs through the dust-proof cover 4 along the vertical direction, and the side of the dovetail groove 48 close to the photoelectric switch runs through the dust-proof cover 4. A dovetail bar 54 is integrally formed on the rack 51. The dovetail bar 54 is adapted to the limiting groove, and the dovetail bar 54 is slidably mounted in the dovetail groove 48. A micro motor 444 is installed on the side of the water baffle 44 close to the photoelectric switch. A gear 445 meshing with the rack 51 is installed on the rotating shaft of the micro motor 444. When the light-blocking plate 443 blocks the light of the portal photoelectric switch 8, the micro motor 444 will rotate, thereby driving the rack 51 and the first mounting rod 52 to slide vertically. The first mounting rod 52 extends towards the side close to the movement button 45.

[0066] Refer to Figure 2 With Figure 4, the dust collection box 143 is located on the side of the water receiving box 141 close to the rear shell 16. Taking the dust collection box 143 as a rectangular box body as an example, the length direction of the dust collection box 143 is the same as that of the water receiving box 141. The top of the dust collection box 143 is open. A sewage outlet 144 is provided on one side of the bottom of the dust collection box 143 along the length direction away from the condensate outlet 142, and the sewage outlet 144 is communicated with the water tank 3. The bottom of the dust collection box 143 gradually becomes higher from the side where the sewage outlet 144 is opened to the other side along its own length direction. Thus, the dust and the sewage for flushing the dust separation net 42 can flow to the sewage outlet 144 under the action of gravity and enter the water tank 3. A partition is integrally formed inside the water tank 3, and the partition divides the water tank 3 into a water collection chamber 33 and a sewage chamber 34, and the water collection chamber 33 is not communicated with the sewage chamber 34. The condensate outlet 142 is communicated with the water collection chamber 33, the sewage outlet 144 is communicated with the sewage chamber 34, and the magnetic float 32 is installed in the water collection chamber 33.

[0067] Referring to Figure 4 , Figure 7 and Figure 8 , the flushing mechanism 6 includes a micro water pump 61, a water inlet pipe 62, a water outlet pipe 63, a spray head 64 and a second mounting rod 65. The micro water pump 61 is installed on the top of the water receiving chassis 14. One end of the water inlet pipe 62 is installed at the water inlet of the micro water pump 61, and the other end passes through the water receiving chassis 14 and is inserted into the water collection chamber 33. One end of the water outlet pipe 63 is installed at the water outlet of the micro water pump 61, and the other end is in a closed state. The second mounting rod 65 is located on the side of the dust separation net 42 close to the air inlet 161. The water outlet pipe 63 is installed on the side of the second mounting rod 65 close to the dust separation net 42 through a clamp, and the spray head 64 is installed on the side wall of the water outlet pipe 63 close to the dust separation net 42 to flush the dust separation net 42. The second mounting rod 65 is located above the first mounting rod 52, and the second mounting rod 65 is integrally formed on the rack 51, and the extending direction of the second mounting rod 65 is the same as that of the first mounting rod 52. The sewage for flushing the dust separation net 42 will flow into the dust collection box 143 and then into the sewage chamber 34.

[0068] Referring to Figure 6 and Figure 7 , the water removal mechanism 7 includes a water absorbent cotton 71, a pressing plate 72 and a third mounting rod 73. The third mounting rod 73 is located above the second mounting rod 65, and the third mounting rod 73 is integrally formed on the rack 51. The third mounting rod 73 is located on the side of the dust separation net 42 close to the air inlet 161, and the extending direction of the third mounting rod 73 is the same as that of the second mounting rod 65. The water absorbent cotton 71 is adhesively installed on the side of the third mounting rod 73 close to the dust separation net 42, and the water absorbent cotton 71 abuts against the dust separation net 42. The pressing plate 72 is located on the side of the dust separation cover 4 close to the dust collection box 143. When the water absorbent cotton 71 moves to the position of the pressing plate 72, the pressing plate 72 squeezes the water absorbent cotton 71 to squeeze out the water in the water absorbent cotton 71.

[0069] Refer to Figure 6 With Figure 7 On one side of the extrusion plate 72 close to the third mounting rod 73, an arc-shaped protrusion 74 is integrally formed. When the water-absorbing cotton 71 moves to the position of the arc-shaped protrusion 74, it is subjected to an extrusion force, thereby squeezing out the water. A diversion plate 75 is also integrally formed at the bottom of the extrusion plate 72. Then, the water flow for flushing falls into the dust collection box 143 under the action of the diversion plate 75 after passing through the arc-shaped protrusion 74. Among them, diversion grooves 76 are provided on both the arc-shaped protrusion 74 and the diversion plate 75. There are multiple diversion grooves 76, and the multiple diversion grooves 76 are arranged at intervals along the horizontal direction, thereby reducing the risk of splashing when water falls on the arc-shaped protrusion 74.

[0070] The implementation principle of a dehumidifier according to an embodiment of the present application is as follows: When assembling and producing the dehumidifier, the heat sink 22, the evaporation sheet 23, the refrigeration sheet 24, the fan 25, the power supply board 26, the photocatalyst net 213, and the negative ion generator 215 are successively installed on the air guide housing 21 to form a large module. Then, the entire large module is installed inside the upper housing 11. After that, the base 12 is installed on the upper housing 11 through the support columns 13. Finally, the water tank 3 is installed on the base 12 by snap connection.

[0071] When it is necessary to clean the dust on the dust separation cover 4, press the moving button 45 to make the water baffle 44 block the opening of the long slot 41. At this time, the light baffle 443 blocks the light of the portal photoelectric switch 8. After the control center receives the signal, the micro motor 444 starts to operate, thereby driving the rack 51 to move downward, and the dust removal brush 53, the spray head 64, and the water-absorbing cotton 71 move downward synchronously.

[0072] Among them, there are three states during cleaning. The first state: The spray head 64 does not spray water, and only the dust removal brush 53 cleans the dust on the dust separation net 42. At this time, the water-absorbing cotton 71 can wipe the position cleaned by the dust removal brush 53 to further clean the dust on the dust separation net 42.

[0073] The second state: When the water pressure of the spray head 64 during spraying is relatively low, during cleaning, the spray head 64 first sprays water, so that the water flows down along the dust separation net 42 under the action of gravity to wet the dust on the dust separation net 42, and then the dust removal brush 53 moves to clean the wetted dust, thereby reducing the risk of dust flying everywhere during the cleaning of the dust removal brush 53. At this time, the water-absorbing cotton 71 adsorbs the remaining water droplets on the dust separation net 42 and also adsorbs the wetted dust on the dust separation net 42.

[0074] The third state: When the water pressure of the sprinkler head 64 is relatively high during cleaning, the dust removal brush 53 first cleans the dust on the dust separation net 42, and then the sprinkler head 64 immediately performs high-pressure flushing on the dust separation net 42 that has been brushed by the dust removal brush 53. Subsequently, the water absorption cotton 71 adsorbs the water droplets on the dust separation net 42 after flushing.

[0075] In any of the above states, the dust cleaned by the dust removal brush 53 will fall into the dust collection box 143. Similarly, the sewage from flushing will also flow into the dust collection box 143, and the sewage in the dust collection box 143 will flow into the sewage chamber 34.

[0076] Since there will be water droplets remaining on the dust separation net 42 after being sprayed and washed by the sprinkler head 64, and the water absorption surface can adsorb the remaining water droplets. When the water absorption cotton 71 moves to the position of the arc-shaped protrusion 74, the arc-shaped protrusion 74 squeezes the water absorption cotton 71 to squeeze out the water inside the water absorption cotton 71. Then the micro-motor 444 rotates in reverse to drive the rack 51 to move upward, and the water absorption cotton 71 will be further squeezed by the arc-shaped protrusion 74 to further squeeze out the water. At the same time, the sprinkler head 64 will also stop spraying water. During the upward movement of the water absorption cotton 71, the water absorption cotton 71 will adsorb the water droplets on the dust separation net 42 again. When the water absorption cotton 71 moves to the initial position, pull the locking button 47 to restore the water baffle 44 to the initial position so as not to block the long slot 41.

[0077] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
