Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidifiers, and in particular relates to a dehumidifier which is convenient for defrosting. Background Art

[0002] A dehumidifier is a common electrical appliance that works by condensing water molecules in the air and then discharging the treated dry air to reduce indoor humidity, keep the environment comfortable, and avoid moisture and mildew.

[0003] Chinese patent publication number CN215892595U discloses a low-temperature dehumidifier with back-blowing defrosting, including a compressor, a fin condenser connected to the compressor, and a fin evaporator connecting the compressor and the fin condenser. The fin condenser and the fin evaporator are arranged in the same air duct, and a two-way fan is provided in the air duct.

[0004] The above technical solution uses a two-way fan that rotates in opposite directions, that is, the wind direction generated is from the fin condenser to the fin evaporator. After the air enters the dehumidifier, it first passes through the fin condenser, absorbs the heat of the refrigerant in the fin condenser and heats up, and then the air with higher temperature passes through the fin evaporator to melt and remove the frost on the surface of the fin evaporator, and then the air is discharged from this end to achieve defrosting. However, in the process of defrosting, the hot air will directly contact the fin evaporation, causing the frost to melt, but at this time the melted water molecules in the air will be blown into the air along with the air, resulting in a large amount of moisture in the defrosted air, which makes the originally dry space faster to become humid, thereby extending the efficiency of subsequent dehumidification.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a dehumidifier which is convenient for defrosting.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0009] Two ventilation frames are fixedly connected to the upper side of the dehumidifier box, fans are slidably connected to the inner walls of the two ventilation frames, blocking blocks are fixedly connected to the lower sides of the two fans, and movable openings are opened on the adjacent sides of the two ventilation frames, and the inner walls of the movable openings are slidably matched with lifting blocks fixedly connected to the fans;

When the operating motor rotates, it drives the gear to rotate in the opposite direction, and then the gear causes the first screw and the second screw to rotate in opposite directions, so that the two lifting blocks can move in opposite directions, so that the fan is driven to move in different directions, so that the two blocks change their positions.

[0012] Optionally, a load-bearing frame is fixedly connected to the lower side of the dehumidifier box, a liquid storage frame is slidably matched to the inner wall of the load-bearing frame, and a drain port is provided on the lower side of the inner wall of the dehumidifier box.

The transparent plate in the observation port can facilitate personnel to observe the storage situation of the liquid in the liquid storage frame.

[0014] Optionally, the lower side of the load-bearing frame is rotatably matched with a plurality of pulleys, which increase the convenience of moving the equipment.

[0015] Optionally, a dustproof net is fixedly connected to the upper side of the ventilation frame, and the dustproof net is convenient for filtering the air flowing in the ventilation frame, thereby reducing the damage caused by dust entering the dehumidification box to the internal components.

[0017] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0018] By setting up the copper tube, it can be achieved that when dehumidifying, the air passes through the serpentine evaporator from the outside of the copper tube to condense the moisture in the air and realize dehumidification. When the serpentine evaporator needs to be defrosted, the upper side of the serpentine evaporator is blocked to make the air flow from the inside of the copper tube, and the heat generated by the serpentine condenser is transferred to the serpentine evaporator through backblowing, and the wind will not directly contact the serpentine evaporator, reducing the direct contact with frost during the defrosting process, resulting in a large amount of water molecules in the air, causing secondary moisture to the air, reducing the efficiency of subsequent dehumidification, thereby improving the efficiency of subsequent dehumidification.

DETAILED DESCRIPTION

[0028] The utility model will now be further described in detail with reference to the accompanying drawings.

[0029] See also Figure 1-4 As shown, in this embodiment, a dehumidifier for easy defrosting is provided, including a dehumidification box 1, a compressor 2 is fixedly connected to the lower side of the inner wall of the dehumidification box 1, a serpentine condenser 3 and a serpentine evaporator 4 are installed on the compressor 2, and a copper tube 5 located on the inner wall of the serpentine condenser 3 and the inner wall of the serpentine evaporator 4 is fixedly connected to the inner wall of the dehumidification box 1;

[0030] Two ventilation frames 6 are fixedly connected to the upper side of the dehumidifier box 1, and fans 7 are slidably connected to the inner walls of the two ventilation frames 6. Blocks 8 are fixedly connected to the lower sides of the two fans 7. A movable opening 9 is opened on the adjacent side of the two ventilation frames 6, and a lifting block 10 fixedly connected to the fan 7 is slidably matched to the inner wall of the movable opening 9;

[0031] The two blocking blocks 8 have different shapes, one is round and the other is square, with a circular hole having the same inner diameter as the copper tube 5;

[0032] A conversion mechanism 11 that cooperates with two lifting blocks 10 is installed on the upper side of the dehumidification box 1.

[0033] One aspect of the application of this embodiment is that when in use, two fans 7 can be started at the same time, and the two fans 7 have different directions, so that air is drawn in from the position of the serpentine evaporator 4 and discharged from the position of the serpentine condenser 3. When the air contacts the serpentine evaporator 4, the serpentine evaporator 4 is in a low temperature state, and the moisture in the air condenses on the surface of the serpentine evaporator 4.

[0034] When defrosting is needed, the conversion mechanism 11 can be started, and the two lifting blocks 10 can move in opposite directions in the movable opening 9, so that one of the blocking blocks 8 is separated from the copper tube 5, and the other blocking block 8 blocks the inner wall of the dehumidification box 1, and then the fan 7 is started in reverse. Since the other blocking block 8 blocks the inside of the dehumidification box 1, the air volume will first flow from the copper tube 5, and take away the heat of the serpentine condenser 3. The frost on the surface of the serpentine evaporator 4 is removed through conduction of the copper tube 5 inside the serpentine evaporator 4, and the warm air will not come into contact with the serpentine evaporator 4, which can reduce the content of melted water molecules in the defrosted air and reduce the possibility of the air becoming humid again due to defrosting.

[0035] By setting the copper tube 5, it can be achieved that when dehumidifying, the air passes through the serpentine evaporator 4 from the outside of the copper tube 5 to condense the moisture in the air to achieve dehumidification. When the serpentine evaporator 4 needs to be defrosted, the upper side of the serpentine evaporator 4 is blocked, so that the air flows from the inside of the copper tube 5, and the heat generated by the serpentine condenser 3 is transferred to the serpentine evaporator 4 through backblowing, and the wind will not directly contact the serpentine evaporator 4, thereby reducing the direct contact with frost during the defrosting process, resulting in a large amount of water molecules in the air, causing secondary moisture to the air, reducing the efficiency of subsequent dehumidification, and thus improving the efficiency of subsequent dehumidification.

[0036] The conversion mechanism 11 of this embodiment includes a hidden groove 111 opened on the upper side of the dehumidifier box 1, an operating motor 112 fixedly connected to the lower side of the inner wall of the hidden groove 111, a first screw rod 113 fixedly connected to the output end of the operating motor 112 and threadedly matched with one of the two lifting blocks 10, a second screw rod 114 rotatably matched with the inner wall of the hidden groove 111 and threadedly matched with the other of the two lifting blocks 10, and a gear 115 installed on the first screw rod 113 and the second screw rod 114 and meshing with each other;

[0037] When the operating motor 112 rotates, the gear 115 is driven to rotate in the opposite direction, and then the gear 115 causes the first screw rod 113 and the second screw rod 114 to rotate in opposite directions, so that the two lifting blocks 10 can move in opposite directions, driving the fan 7 to move in different directions, so that the two blocking blocks 8 change their positions.

[0038] The lower side of the dehumidification box 1 of this embodiment is fixedly connected to a load-bearing frame 12, and the inner wall of the load-bearing frame 12 is slidably matched with a liquid storage frame 13. A drain port 14 is opened on the lower side of the inner wall of the dehumidification box 1, and the removed frost water can be discharged from the drain port 14 and collected in the liquid storage frame 13 to facilitate subsequent processing.

[0039] In this embodiment, an observation port 15 is provided on one side of the liquid storage frame 13 , and a transparent plate 16 is fixedly connected to the inner wall of the observation port 15 , so that personnel can observe the storage condition of the liquid in the liquid storage frame 13 through the transparent plate 16 in the observation port 15 .

[0040] The lower side of the load-bearing frame 12 of this embodiment is rotatably matched with a plurality of pulleys 17, and the pulleys 17 increase the convenience of moving the equipment.

[0041] The upper side of the ventilation frame 6 of this embodiment is fixedly connected with a dustproof net 18, which is convenient for filtering the air flowing in the ventilation frame 6 to reduce the damage caused by dust entering the dehumidification box 1 to the internal components.

[0042] A push handle 19 is fixedly connected to one side of the dehumidification box 1 of this embodiment, and the push handle 19 facilitates the convenience of pushing operation by personnel when moving.
