Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and specifically to a dehumidifier. Background Technology

[0002] A dehumidifier, also known as a moisture remover or dehumidifier, typically consists of a fan, heat exchanger, and compressor. Its working principle involves the fan drawing humid indoor air into the main unit, where the heat exchanger and compressor work together to condense the water vapor in the air. The treated, dry air is then expelled from the main unit, and this cycle continues to reduce indoor humidity. The heat exchanger includes an evaporator and a condenser. Over time, the heat exchanger accumulates a lot of dust, which can affect its heat exchange efficiency; therefore, it needs to be cleaned regularly.

[0003] The utility model patent with publication number CN204786863U discloses a new type of dehumidifier. This prior art involves setting a spray pipe above the heat exchanger, and the spray pipe is connected to a water pump through a pipe. The water pump draws water from the water tank to the spray pipe to clean the heat exchanger. However, this prior art still has structural deficiencies. Its spray pipe is fixed above the heat exchanger and cannot be raised or lowered relative to the heat exchanger for cleaning, resulting in unsatisfactory cleaning effect and efficiency.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this invention proposes a dehumidifier in which a spray pipe is placed around the outer periphery of a heat exchanger, and a drive assembly is provided to drive the spray pipe to rise and fall relative to the heat exchanger, resulting in better cleaning effect and higher cleaning efficiency.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows: A dehumidifier includes a main unit with a heat exchanger, a compressor, and a fan fixed on it. The compressor is located inside the heat exchanger, and an air duct is formed between the heat exchanger and the fan. A spray pipe surrounds the outer periphery of the heat exchanger. The main unit is equipped with a drive assembly for driving the spray pipe to move up and down relative to the heat exchanger. This arrangement, with the spray pipe surrounding the heat exchanger and the drive assembly for moving the spray pipe up and down relative to the heat exchanger, results in better cleaning effect and higher cleaning efficiency.

[0007] According to the above scheme, the cross-sectional shape of the spray pipe is the same as that of the heat exchanger; the cross-sectional shape of the spray pipe and the heat exchanger can be any one of the following: U-shaped structure, L-shaped structure, polygonal structure, arc structure, or ring structure. This arrangement allows the spray pipe to thoroughly clean the heat exchanger from all directions.

[0008] According to the above scheme, the driving component includes a motor and a lead screw. The motor is fixed on the main unit, and the lead screw is vertically installed on the main unit. The lead screw is driven to rotate by the motor. A nut sleeve is fixed on the spray pipe, and the nut sleeve is threadedly connected to the lead screw. A guide component is provided between the spray pipe and the main unit. With this configuration, when the motor is working, it drives the lead screw to rotate, and the lead screw and nut sleeve undergo threaded movement. The nut sleeve drives the spray pipe to rise and fall vertically along the lead screw.

[0009] According to the above scheme, the guiding assembly includes multiple sliders mounted on the spray pipe and multiple guide rods vertically mounted on the main unit, with the sliders and guide rods slidably connected. This configuration allows the spray pipe to move vertically up and down along the guide rods while the sliders and guide rods are slidably connected.

[0010] According to the above scheme, the spray pipe is equipped with a water inlet and multiple nozzles. The water inlet is connected to a water supply assembly, and the multiple nozzles are evenly distributed on the spray pipe, with the nozzles arranged horizontally or at an angle towards the heat exchanger. With this configuration, the water supply assembly supplies water into the spray pipe, which is then distributed to the multiple nozzles for spraying, thereby cleaning the heat exchanger.

[0011] According to the above scheme, the water supply assembly includes a water tank and a water pump. The water pump's inlet is connected to the water tank or an external water source via an inlet pipe, and the water pump's outlet is connected to the inlet via an outlet pipe. The water tank is equipped with a drain outlet, which has a plug for opening or closing the drain outlet. With this configuration, when the water pump is working, it draws water from the water tank or external water source to the spray pipe. When drainage is needed, the plug is removed to open the drain outlet.

[0012] According to the above scheme, a heating pack is installed on the water outlet pipe. This design allows the heating pack to heat water, enabling the hot water to achieve a high-temperature sterilization effect when cleaning the heat exchanger.

[0013] According to the above scheme, a water receiving tray is fixed on the water tank, and the water receiving tray is located around the bottom of the heat exchanger. The water receiving tray is provided with multiple return water holes that communicate with the water tank. With this configuration, the water receiving tray can be used to collect the water after cleaning the heat exchanger, and then return it to the water tank for recycling.

[0014] According to the above design, the main unit is equipped with multiple casters on its bottom. This design facilitates the movement of the entire dehumidifier and allows for adjustment of its position indoors.

[0015] The beneficial effects of this utility model are: This invention features a spray pipe that surrounds the heat exchanger and is equipped with a drive assembly to move the spray pipe up and down relative to the heat exchanger, resulting in better cleaning effect and higher cleaning efficiency.

Detailed Implementation

[0018] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 5 As shown, the dehumidifier of this utility model includes a main unit, on which a heat exchanger 5, a compressor 19, and a fan 16 are fixed. The compressor 19 is located inside the heat exchanger 5, and an air duct 17 is formed between the heat exchanger 5 and the fan 16. A spray pipe 9 surrounds the heat exchanger 5. A drive assembly is provided on the main unit to drive the spray pipe 9 to move up and down relative to the heat exchanger 5. This arrangement, with the spray pipe 9 surrounding the heat exchanger 5 and the drive assembly used to move the spray pipe 9 up and down relative to the heat exchanger 5, results in better cleaning effect and higher cleaning efficiency.

[0020] Preferably, the heat exchanger 5 has a finned structure.

[0021] Furthermore, the cross-sectional shape of the spray pipe 9 is the same as that of the heat exchanger 5; the cross-sectional shape of the spray pipe 9 and the heat exchanger 5 can be any one of a U-shaped structure, an L-shaped structure, a polygonal structure, an arc-shaped structure, or a ring-shaped structure. This arrangement allows the spray pipe 9 to thoroughly clean the heat exchanger 5 from all directions.

[0022] Preferably, the cross-sectional shape of the spray pipe 9 and the cross-sectional shape of the heat exchanger 5 are U-shaped.

[0023] Furthermore, the drive assembly includes a motor 6 and a lead screw 12. The motor 6 is fixed to the main unit, and the lead screw 12 is vertically mounted on the main unit. The lead screw 12 is driven to rotate by the motor 6. A nut sleeve 21 is fixed on the spray pipe 9, and the nut sleeve 21 is threadedly connected to the lead screw 12. A guide assembly is provided between the spray pipe 9 and the main unit. With this configuration, when the motor 6 is working, it drives the lead screw 12 to rotate, causing the lead screw 12 and the nut sleeve 21 to undergo threaded movement. The nut sleeve 21 drives the spray pipe 9 to rise and fall vertically along the lead screw 12.

[0024] The lead screw 12 is equipped with a bearing between itself and the main unit, which makes the lead screw 12 rotate more smoothly; and the drive method of motor 6 and lead screw 12 working together allows for more precise control of the spray pipe 9 in terms of lifting speed and lifting position.

[0025] Furthermore, the guiding assembly includes multiple sliders 20 mounted on the spray pipe 9 and multiple guide rods 11 vertically mounted on the main unit, with the sliders 20 and guide rods 11 slidably connected. This configuration allows the spray pipe 9 to move vertically up and down along the guide rods 11 while the sliders 20 and guide rods 11 are slidably connected.

[0026] Preferably, the slider 20 and the guide rod 11 are in two sets.

[0027] Furthermore, the spray pipe 9 is provided with a water inlet 10 and multiple nozzles 8. The water inlet 10 is connected to a water supply assembly, and the multiple nozzles 8 are evenly distributed on the spray pipe 9, and the multiple nozzles 8 are arranged horizontally or at an angle towards the heat exchanger 5. With this arrangement, the water supply assembly supplies water into the spray pipe 9, and then distributes it to the multiple nozzles 8 to spray out, thereby cleaning the heat exchanger 5.

[0028] Furthermore, the water supply assembly includes a water tank 14 and a water pump 2. The inlet of the water pump 2 is connected to the water tank 14 or an external water source via an inlet pipe 1, and the outlet of the water pump 2 is connected to the inlet 10 via an outlet pipe 3. The water tank 14 is provided with a drain outlet 15, and the drain outlet 15 is provided with a plug for opening or closing the drain outlet 15. With this configuration, when the water pump 2 is working, it draws water from the water tank 14 or the external water source to the spray pipe 9. When drainage is required, the plug is removed to open the drain outlet 15 to drain the water.

[0029] Furthermore, a heating element 4 is provided on the water outlet pipe 3. This arrangement allows the heating element 4 to heat water, enabling the hot water to achieve a high-temperature sterilization effect when cleaning the heat exchanger 5.

[0030] The water outlet pipe 3 includes a corrugated pipe 7 that can expand and contract.

[0031] Furthermore, a water receiving tray 13 is fixed on the water tank 14, and the water receiving tray 13 is located around the bottom of the heat exchanger 5. The water receiving tray 13 is provided with multiple return water holes 22 that communicate with the water tank 14. With this arrangement, the water receiving tray 13 can be used to collect the water after cleaning the heat exchanger 5, and then return it to the water tank 14 for recycling; after the water has been recycled for a certain period of time, it can be drained and replaced with fresh water.

[0032] The water inlet pipe 1 can also be directly connected to an external fresh water source to clean the heat exchanger 5. The cleaned water enters the water tank 14 through the water receiving tray 13 for collection, and is then directly discharged through the drain outlet of the water tank 14. The cleaned water is not recycled, making the cleaning more thorough. Specifically, there are two water supply modes: one is to circulate water through the water tank 14; the other is to supply water from an external water source, with the water tank 14 used to collect the cleaned water and discharge it uniformly.

[0033] Furthermore, the main unit is equipped with multiple casters 18 on its bottom. This design facilitates the movement of the entire dehumidifier and allows for adjustment of its position indoors.

[0034] The compressor 19 is located inside the heat exchanger 5, the fan 16 is located above the heat exchanger 5, the water tank 14 is located below the heat exchanger 5, and the spray pipe 9 is located around the outer periphery of the heat exchanger 5. The whole machine has a compact structure and occupies little space, making it suitable for home use.
