Description

Technical Field

[0001] The present invention relates to the technical field of dehumidifiers, and specifically relates to a clean dehumidifier for precision instrument processing. Background Art

[0002] A dehumidifier, also known as a moisture extractor, dryer, or dehumidifier, can generally be divided into two categories: household dehumidifiers and industrial dehumidifiers, and belongs to a part of the air-conditioning family. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water container, a casing, and a controller; its working principle is: the fan draws 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 the processed dry air is discharged outside the machine. In this way, the indoor humidity is maintained at an appropriate relative humidity through circulation.

[0003] However, the current clean dehumidifier for precision instrument processing sets a filter screen at the air inlet of the dehumidifier to filter the air. The air is condensed into water droplets through the evaporator to complete dehumidification. The dehumidified air is heated according to needs through the condenser, and the dry air is discharged. It is necessary to regularly clean the evaporator and the filter screen.

[0004] The prior art has the following defects:

[0005] 1. The air is filtered through a whole-piece filter screen. When cleaning the filter screen, a small brush is usually used to rub and clean the outer side of the filter screen. The filter screen close to the inside of the dehumidifier is not cleaned. When used again, it is easy to inhale the loose dust into the inside of the dehumidifier and adsorb it on the internal electrical components, affecting the dehumidification effect. If the whole-piece filter screen is disassembled and washed, it is quite cumbersome.

[0006] 2. When the dehumidifier is used for a long time, a thick layer of frost will form on the evaporator. Currently, when defrosting, the outer inspection plate is disassembled and defrosting agent is sprayed for defrosting. Not only is the operation cumbersome, but it also needs to be sprayed on the entire conveying pipeline. The spraying is not comprehensive, the defrosting efficiency is low, and it is very easy to cause incomplete defrosting, affecting dehumidification. Moreover, the evaporator defrosting and the filter screen dust removal are cleaned separately, wasting time.

[0007] 3. Currently, the dehumidified water of some dehumidifiers is collected through a water tank. Some water tanks are not provided with an alarm mechanism, and the water inside the water tank is easy to overflow, polluting the ground. And if it comes into contact with the internal electrical components of the dehumidifier, it is easy to cause a short circuit and damage. Summary of the Invention

[0008] In view of the problems in the prior art, the present invention provides a clean dehumidifier for precision instrument processing.

The two side plates are slidably connected to the two chutes respectively. A connecting plate is fixedly connected between the two side plates. The two side plates are respectively fixed to the two racks. A clamping plate is rotatably connected to the connecting plate. A clamping groove is opened on the dehumidifier body.

[0012] Specifically, the limiting mechanism further includes two first springs. Two first springs are clamped between the two side plates and the dehumidifier body respectively.

[0013] Specifically, the dehumidifying and defrosting mechanism includes an evaporator and a condenser. The evaporator and the condenser are installed in parallel inside the dehumidifier body. A compressor is installed at the bottom of the dehumidifier body. A delivery pipe is connected between the evaporator and the condenser in an S shape. Both ends of the delivery pipe are connected to the compressor. A water leakage port is opened on the dehumidifier body. A guide plate fixed to the dehumidifier body is provided at the bottom of the water leakage port.

[0014] Specifically, the dehumidifying and defrosting mechanism further includes a protective ring. A protective ring is installed on the dehumidifier body outside the evaporator and the water leakage port.

[0015] Specifically, the dehumidifying and defrosting mechanism further includes a top rod and a bottom rod. A top rod fixed to the two racks is slidably connected to the dehumidifier body. Multiple bottom rods are fixedly connected to the bottom of the top rod at equal distances. Heating blocks with an arc-shaped structure and located on the top of the delivery pipe are fixed to the bottoms of the multiple bottom rods.

[0016] Specifically, the air suction mechanism includes a mounting plate. A mounting plate in a cross-shaped structure corresponding to the condenser is fixed to the back side of the dehumidifier body. A protective net is provided between the dehumidifier body and the mounting plate, and a fan is installed at the center of the mounting plate.

[0017] Specifically, the collection mechanism includes a water tank. A water tank located at the bottom of the deflector is placed inside the dehumidifier body. A sliding frame that abuts against the water tank is slidably connected to the side of the dehumidifier body. Two second springs are clamped between the sliding frame and the dehumidifier body, and a pedal is fixed to the side of the sliding frame.

[0018] Specifically, the alarm mechanism includes a fixing plate. The fixing plate is fixed to the water tank. A sliding rod is slidably connected to the fixing plate. A floating block is fixed to the bottom of the sliding rod. A metal plate is fixed inside the sliding rod with a T-shaped cross-section. Two touch plates are relatively fixed to the fixing plate with respect to the sliding rod. The touch plates abut against the side wall of the sliding rod. A power supply is installed on the fixing plate. The power supply is electrically connected to one of the touch plates. An alarm is installed on the fixing plate.

Metal seats are fixed to the bottoms of the two mounting seats. A conductive plate is slidably connected between the two metal seats and the two mounting seats. Wires are installed on the two metal seats.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) For the clean dehumidifier for precision instrument processing of the present invention, multiple groups of filtering mechanisms are provided on the dehumidifier body. The filtering mechanisms can filter impurities in the air to protect internal electrical components. When it is necessary to clean the ash of multiple filter meshes without disassembling, the driving mechanism on the dehumidifier body can be pulled. After the rack drives the gear to rotate clockwise, multiple filter meshes can be rotated and opened simultaneously around the rotating shaft. At this time, the rack can be limited by the limiting mechanism to ensure that the filter meshes do not reset, which is convenient for quickly cleaning both sides of the filter meshes in the non-disassembled state, avoiding the inability to clean the inner side and ensuring the dehumidification effect of the dehumidifier body.

[0021] (2) For the clean dehumidifier for precision instrument processing of the present invention, ejector rods are provided on the two racks. When cleaning the dust on the filter mesh, since the rack is in a descending state, the heating block at the bottom of the bottom rod abuts against the delivery pipe, and after the heating block is started, the frost on the surface of the delivery pipe can be cleaned, thereby realizing defrosting of the evaporator while cleaning the dust on the filter mesh, which is fast and efficient.

[0022] (3) A clean dehumidifier for precision instrument processing according to the present invention is provided with an alarm mechanism on the water tank. When the water inside the water tank lifts the floating block, the metal plate on the sliding rod rises. Further, when the metal plate touches the two touch plates, the power supply is connected to the alarm, and the alarm starts to alarm. At this time, there is still a certain distance from the water level to the top of the water tank. If the maintenance personnel do not handle the water inside the water tank in time, as the water level rises, the sliding rod pushes the conductive plate between the two metal seats to rise until the conductive plate separates from the metal seat, and the power cord is powered off, stopping the dehumidifier from working to protect it from water seepage damage.

When it is necessary to clean them regularly but not cleaned, the connecting plate 402 is pulled to drive the two side plates 401 to drive the racks 303 to descend. Further, the two first springs 403 are compressed. After the two racks 303 descend, they drive the two groups of gears 302 to rotate clockwise, thereby realizing the opening of multiple filter screens 202, facilitating the cleaning of the dust on both sides, avoiding the inability to clean the inside, and ensuring the dehumidification effect of the dehumidifier body 1. When the connecting plate 402 is at the bottom of the clamping groove 405, the clamping plate 404 on the connecting plate 402 is rotated, so that the clamping plate 404 is clamped into the inside of the clamping groove 405, realizing the limitation of the filter screen 202, facilitating the cleaning of the dust, and the sealing strip 203 increases the compactness when multiple filter screens 202 are closed.

[0036] Specifically, the dehumidifying and defrosting mechanism 7 includes an evaporator 704 and a condenser 705. The evaporator 704 and the condenser 705 are installed in parallel inside the dehumidifier body 1. A compressor 710 is installed at the bottom of the dehumidifier body 1. The evaporator 704 and the condenser 705 are connected in an S shape by a delivery pipe 706. Both ends of the delivery pipe 706 are connected to the compressor 710. A water leakage port 708 is provided on the dehumidifier body 1, and a deflector 709 fixed to the dehumidifier body 1 is provided at the bottom of the water leakage port 708. The dehumidifying and defrosting mechanism 7 further includes a protective ring 707. A protective ring 707 located outside the evaporator 704 and the water leakage port 708 is installed on the dehumidifier body 1. The air suction mechanism 5 includes a mounting plate 501. A mounting plate 501 in a cross shape corresponding to the condenser 705 is fixed to the back side of the dehumidifier body 1. A protective net 502 is provided between the dehumidifier body 1 and the mounting plate 501. A fan 503 is installed at the center of the mounting plate 501. When processing precision instruments, it is necessary to dehumidify the indoor air. The dehumidifier body 1 is moved to the processing site through rollers. The fan 503 is started to suck the air in front of the dehumidifier body 1 into the dehumidifier body 1. The dust and debris in the air are filtered by the filter net 202. After the compressor 710 is started, the internal gas is transported through the delivery pipe 706. The evaporator 704 works at this time to condense the water vapor in the air into water droplets. The water droplets fall from the water leakage port 708 onto the deflector 709 and are finally collected by the water tank 601. The cold air passes through the condenser 705, and the air can be dried by the condenser 705 and discharged from the protective net 502 into the room.

[0037] Specifically, the dehumidifying and defrosting mechanism 7 further includes a top rod 701 and a bottom rod 702. A top rod 701 fixed to two racks 303 is slidably connected to the dehumidifier body 1. A plurality of bottom rods 702 are equidistantly and fixedly connected to the bottom of the top rod 701. Heating blocks 703 with an arc structure and located on the top of the delivery pipe 706 are fixed to the bottoms of the plurality of bottom rods 702. When the rack 303 descends, it can be limited by being clamped into the internal card slot 405 through the clamping plate 404. When the rack 303 moves, it drives the top rod 701 to descend. Further, the heating blocks 703 at the bottoms of the plurality of bottom rods 702 are in contact with the delivery pipe 706 on the evaporator 704. The heating blocks 703 are started to heat, so that heat is transmitted to the delivery pipe 706, and then the frost on its surface is melted. It realizes defrosting while cleaning the filter net 202 and shortens the maintenance time.

[0038] Specifically, the collecting mechanism 6 includes a water tank 601, the water tank 601 located at the bottom of the guide plate 709 is placed inside the dehumidifier body 1, and the side of the dehumidifier body 1 is slidably connected to a slide 602 that contacts the water tank 601. Two second springs 604 are clamped between the slide 602 and the dehumidifier body 1, and a pedal 603 is fixed to the side of the slide 602; the alarm mechanism 8 includes a fixed plate 801, a fixed plate 801 is fixed on the water tank 601, and a sliding plate 602 is provided on the fixed plate 801. The sliding rod 803 is connected to the fixed plate 801, and a floating block 802 is fixed to the bottom of the sliding rod 803. A metal plate 804 is fixed inside the sliding rod 803 with a T-shaped cross section. Two touch plates 805 are fixed relative to the sliding rod 803 on the fixed plate 801. The touch plates 805 are in contact with the side walls of the sliding rod 803. A power supply 806 is installed on the fixed plate 801. The power supply 806 is electrically connected to one of the touch plates 805. An alarm 807 is installed on the fixed plate 801. The alarm 807 is connected to the other The contact plate 805 is electrically connected, and two mounting seats 808 are relatively fixed on the inner bottom of the dehumidifier body 1. The bottoms of the two mounting seats 808 are fixed with metal seats 809. A conductive plate 811 is slidably connected between the two metal seats 809 and the two mounting seats 808. Wires 810 are installed on the two metal seats 809. As the water level inside the water tank 601 rises, the floating block 802 is pushed up, and the floating block 802 pushes the slide rod 803 to realize the metal plate 804 inside the slide rod 803 and the fixed The two contact plates 805 on the plate 801 collide with each other. At this time, the power supply 806 of the alarm 807 is turned on. The alarm 807 reminds the worker to process the water inside the water tank 601. If the worker is not nearby, the metal plate 804 continues to move, and the alarm 807 continues to alarm. As the slide bar 803 rises, the conductive plate 811 on the two metal seats 809 is pushed. As the water level rises, the conductive plate 811 separates from the two metal seats 809, and the wire 810 cuts off the power supply of the dehumidifier body 1 to prevent water overflow and damage to the circuit.

[0039] When the present invention is used, first, when processing precision instruments, it is necessary to dehumidify the indoor air. The dehumidifier body 1 is moved to the processing site via the rollers, and the fan 503 is started to suck the air in front of the dehumidifier body 1 into the interior of the dehumidifier body 1. The dust and debris in the air are filtered by the filter 202. After the compressor 710 is started, the internal gas is transported through the delivery pipe 706. The evaporator 704 works at this time to condense the water vapor in the air into water droplets. The water droplets fall from the leak 708 onto the guide plate 709 and are finally collected by the water tank 601. The cold air passes through the condenser 705, and the air can be dried by the condenser 705 and discharged from the protective net 502 to the room.

[0040] Then, when the air is sucked in by the fan 503, it is first filtered by multiple filter nets 202, and sundries in the air adhere to their surfaces. It is necessary to clean them regularly. When not cleaned, the connecting plate 402 is pulled to drive the two side plates 401 to drive the rack 303 to descend. Further, the two first springs 403 are compressed. After the two racks 303 descend, they drive the two groups of gears 302 to rotate clockwise, thereby realizing the opening of the multiple filter nets 202, facilitating the cleaning of the dust on both sides, avoiding the inability to clean the inside, and ensuring the dehumidification effect of the dehumidifier body 1. When the connecting plate 402 is at the bottom of the card slot 405, the clamping plate 404 on the connecting plate 402 is rotated to realize the clamping of the clamping plate 404 into the inside of the card slot 405, realizing the limit of the filter net 202, facilitating the cleaning of the dust, and the sealing strip 203 increases the compactness when the multiple filter nets 202 are closed;

[0041] Next, when the rack 303 descends, it can be limited by clamping the clamping plate 404 into the inside of the card slot 405. When the rack 303 moves, it drives the ejector rod 701 to descend. Further, the heating blocks 703 at the bottoms of the multiple bottom rods 702 are in contact with the delivery pipes 706 on the evaporator 704. The heating blocks 703 are started to heat, realizing the transfer of heat to the delivery pipes 706, and then melting the frost on their surfaces, realizing defrosting while cleaning the filter net 202 and shortening the maintenance time;

[0042] Finally, as the water level in the water tank 601 rises, it pushes the floating block 802 to rise. After the floating block 802 pushes the sliding rod 803, the metal plate 804 inside the sliding rod 803 is in contact with the two touch plates 805 on the fixed plate 801. At this time, the power supply 806 of the alarm 807 is turned on, and the alarm 807 prompts the worker to handle the water inside the water tank 601. If the worker is not nearby, at this time the metal plate 804 is still moving, and the alarm 807 keeps alarming. As the sliding rod 803 rises, it pushes the conductive plates 811 on the two metal seats 809. As the water level rises, the conductive plates 811 are separated from the two metal seats 809, and the wire 810 cuts off the power supply of the dehumidifier body 1 to avoid water overflow damaging the circuit.
