Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, and in particular to a dehumidifier. Background Technology

[0002] A dehumidifier is a household or commercial appliance that improves environmental comfort and prevents mold growth by reducing air humidity. Its core working principle generally employs refrigeration dehumidification, which uses a refrigeration system to cool humid air below its dew point temperature, causing water vapor to condense into water. The dried air is then heated and returned to the room. Current dehumidifiers typically include core components such as a frame, casing, compressor, evaporator, condenser, and fan. Specifically, a continuous airflow duct is formed inside the casing, with the evaporator and condenser arranged sequentially along the duct. The fan drives air to flow in from the inlet, passing through the evaporator (for cooling and dehumidification) and the condenser (for heating and rehydration), finally exiting from the outlet.

[0003] However, this traditional duct layout has several inherent drawbacks: First, it easily leads to airflow short-circuiting. In this layout, the air inlet and outlet are usually located on the same side or adjacent sides of the equipment, and are relatively close together. The relatively dry and warm air just discharged from the outlet is highly likely to be immediately drawn back into the inlet. This "airflow short-circuiting" phenomenon severely interferes with the machine's perception of the actual indoor humidity, resulting in reduced dehumidification efficiency, frequent compressor start-stop cycles, wasted energy, and shortened equipment lifespan. Second, space utilization and structural stability need optimization. In traditional layouts, to ensure sufficient heat exchange duct length, the equipment often needs to occupy a large space in the height or depth direction, resulting in a less compact overall form.

[0004] Therefore, there is an urgent need in this field for a new dehumidifier structure that can effectively avoid airflow short-circuiting and optimize spatial layout. Utility Model Content

[0005] Therefore, it is necessary to provide a dehumidifier that addresses the technical problem of airflow short-circuiting in existing dehumidifiers.

[0006] A dehumidifier includes a frame, a housing, a compressor, an evaporator, a condenser, and a fan, with the housing fitted into the frame and the evaporator, condenser, and fan mounted on the housing.

[0007] The frame includes a first mounting part and a second mounting part. The first mounting part is located on one side of the frame, and the second mounting part is located on the other side of the frame adjacent to the first mounting part. The casing is fitted into the first mounting part to form a dehumidification pipe. The evaporator and condenser are installed inside the casing, and the fan is located at one end of the casing. The compressor is installed in the second mounting part, and the compressor is connected to the evaporator and condenser pipes respectively.

[0008] The casing includes an air inlet duct, a dehumidification duct, and an air outlet duct. The dehumidification duct is fitted into the first mounting part along the height of the frame. The air inlet duct connects to the top of the dehumidification duct, and the air outlet duct connects to the bottom of the dehumidification duct. The fan is installed at the end of the air inlet duct away from the dehumidification duct. The evaporator is installed at the bottom of the dehumidification duct. The condenser is installed at the end of the air outlet duct adjacent to the dehumidification duct.

[0009] In one embodiment, the aforementioned air inlet duct and air outlet duct are respectively located on both sides of the dehumidification duct; and the air inlet duct and air outlet duct are respectively connected to the dehumidification duct in a vertical direction to form a Z-shaped flow channel.

[0010] In one embodiment, the air inlet duct is configured as an L-shaped duct, with the inlet end and outlet end of the air inlet duct set at right angles. The outlet end of the air inlet duct is connected to one side wall at the top of the dehumidification duct, and the inlet end of the air inlet duct bends and extends in a preset direction.

[0011] In one embodiment, the aforementioned air outlet duct is configured as an L-shaped duct, with the inlet end and outlet end of the air outlet duct set at right angles. The inlet end of the air outlet duct is connected to one side wall at the bottom of the dehumidification duct, and the outlet end of the air outlet duct bends and extends in a preset direction.

[0012] In one embodiment, the inlet end of the air inlet duct and the outlet end of the air outlet duct extend parallel to each other.

[0013] In one embodiment, the end of the air inlet duct and the end of the air outlet duct extend parallel to the same plane.

[0014] In one embodiment, the aforementioned fan is located at the inlet end of the air inlet duct.

[0015] In one embodiment, the evaporator described above is configured to work in conjunction with the output end of the air inlet duct.

[0016] In one embodiment, the condenser described above is located at the inlet end of the air outlet duct.

[0017] In one embodiment, the evaporator is provided with a water collection tank, which is located on the bottom side of the evaporator and installed at the bottom of the dehumidification pipe.

[0018] In one embodiment, the evaporator is further provided with a drain pump, which is located on the bottom side of the water collection tank and installed on the bottom wall of the dehumidification pipe, with the input end of the drain pump connected to the bottom wall of the water collection tank.

[0019] In one embodiment, the aforementioned air outlet duct is provided with a guide grille, which is installed at the output end of the air outlet duct.

[0020] The aforementioned dehumidifier uses a frame as the main body to support the compressor and the air duct structure, ensuring overall mechanical strength. Furthermore, the compressor is independently mounted in the second mounting section, physically separated from the first mounting section which contains the fan and heat exchanger. This prevents compressor vibration from being directly transmitted to the casing and air duct system, fundamentally reducing additional noise and structural fatigue caused by resonance. Simultaneously, the combination of frame and casing not only facilitates assembly but also provides a robust skeleton for the relatively thin casing, ensuring the stability of the air duct shape and preventing abnormal noise under high air pressure. Secondly… The connection structure of the air inlet duct, dehumidification duct, and air outlet duct forms a continuous, undisturbed U-shaped, L-shaped, or Z-shaped flow channel, which can effectively reduce airflow resistance and deliver more air with the same fan power, thus improving heat exchange efficiency. In addition, the independent setting of the first and second installation sections makes the core functional components relatively independent, greatly improving maintenance convenience. Furthermore, by arranging the dehumidification duct along the height of the frame and placing the air inlet and outlet at the top and bottom respectively, the vertical space is fully utilized, making the overall structure very compact and occupying a small area.

[0028] Please see Figures 1 to 4This utility model discloses a dehumidifier 1, which includes a frame 10, a housing 20, a compressor 30, an evaporator 40, a condenser 50, and a fan 60. The housing 20 is fitted into the frame 10, and the evaporator 40, the condenser 50, and the fan 60 are installed in the housing 20, thus forming the basic structure of the dehumidifier 1. The frame 10 includes a first mounting part 11 and a second mounting part 12. The first mounting part 11 is located on one side of the frame 10, and the second mounting part 12 is located on the other side of the frame 10 adjacent to the first mounting part 11. The housing 20 is fitted into the first mounting part 11 to form a dehumidification pipe 22. The evaporator 40 and the condenser 50 are installed inside the housing 20. The fan 60 is located at one end of the housing 20, so that the fan 60 can drive the airflow inside the housing 20 to flow in a directional manner, so as to achieve air dehumidification through the condenser 50 and the evaporator 40. The compressor 30 is installed in the second mounting part 12, and the compressor 30 is connected to the evaporator 40 and the condenser 50 through pipes, thereby forming a dehumidification functional module. Specifically, the casing 20 includes an air inlet duct 21, a dehumidification duct 22, and an air outlet duct 23. The dehumidification duct 22 is fitted into the first mounting part 11 along the height direction of the frame 10. The air inlet duct 21 connects to the top of the dehumidification duct 22, and the air outlet duct 23 connects to the bottom of the dehumidification duct 22, thus forming a continuous airflow channel. The fan 60 is installed at the end of the air inlet duct 21 away from the dehumidification duct 22. The evaporator 40 is installed at the bottom of the dehumidification duct 22. The condenser 50 is installed at the end of the air outlet duct 23 adjacent to the dehumidification duct 22. Thus, driven by the fan 60, the airflow enters the dehumidification duct 22 from the target indoor space through the air inlet duct 21. After being cooled and dehumidified by the evaporator 40, it is delivered to the air outlet duct 23. The condenser 50 then heats and reheats the dehumidified dry and cold airflow, and then it is output to the target indoor space through the end of the air outlet duct 23 away from the dehumidification duct 22.Based on the above configuration, the dehumidifier 1 of this solution uses the frame 10 as the main body to support the compressor 30 and the air duct structure, ensuring overall mechanical strength. Furthermore, the compressor 30 is independently installed in the second mounting part 12, physically separated from the first mounting part 11 containing the fan 60 and heat exchanger. This prevents the vibration of the compressor 30 from being directly transmitted to the casing 20 and the air duct system, fundamentally reducing additional noise and structural fatigue caused by resonance. Simultaneously, the combination of the frame 10 and the casing 20 not only facilitates assembly, but also provides a robust skeleton for the relatively thin casing 20, ensuring the stability of the air duct shape and preventing vibration under high air pressure. The system generates abnormal noises. Secondly, the connection structure of the air inlet duct 21, dehumidification duct 22, and air outlet duct 23 forms a continuous, undisturbed U-shaped, L-shaped, or Z-shaped flow channel, which can effectively reduce airflow resistance and deliver more air under the same fan power of 60, thus improving heat exchange efficiency. In addition, the independent setting of the first installation part 11 and the second installation part 12 makes the core functional components relatively independent, greatly improving maintenance convenience. Furthermore, by arranging the dehumidification duct 22 along the height direction of the frame 10 and placing the air inlet and outlet at the top and bottom respectively, the vertical space is fully utilized, making the whole unit structure very compact and occupying a small area.

[0029] Furthermore, the air inlet duct 21 and the air outlet duct 23 are respectively located on both sides of the dehumidification duct 22; and the air inlet duct 21 and the air outlet duct 23 are respectively connected to the dehumidification duct 22 in a vertical direction to form a Z-shaped flow channel, so as to ensure that the dehumidifier 1 always draws in humid air from the indoor environment and reduces the intake of the dry and hot air that has just been discharged, thereby improving the overall dehumidification efficiency and speed. At the same time, the condensate in the evaporator 40 can drip smoothly downward under the action of gravity and is not easily carried into the air duct by the airflow, reducing the "drifting" phenomenon. The condensate can be collected in the water storage tank more efficiently, reducing the risk of internal mold growth.

[0030] Furthermore, the air inlet duct 21 is configured as an L-shaped duct, with the input end and output end of the air inlet duct 21 set at a right angle. The output end of the air inlet duct 21 is connected to one side wall of the top of the dehumidification duct 22, and the input end of the air inlet duct 21 bends and extends in a preset direction.

[0031] Furthermore, the air outlet duct 23 is configured as an L-shaped duct, with the input end and output end of the air outlet duct 23 set at a right angle. The input end of the air outlet duct 23 is connected to one side wall at the bottom of the dehumidification duct 22, and the output end of the air outlet duct 23 bends and extends in a preset direction.

[0032] Furthermore, the input end of the air inlet duct 21 and the output end of the air outlet duct 23 are arranged to extend parallel to each other; more specifically, the end of the input end of the air inlet duct 21 and the end of the output end of the air outlet duct 23 extend parallel to the same plane, so that the two can be connected to the indoor space through the same wall in actual application.

[0033] Furthermore, the fan 60 is installed at the input end of the air inlet duct 21 to drive the humid air in the indoor space into the air inlet duct 21.

[0034] Furthermore, the evaporator 40 is configured to work in conjunction with the output end of the air inlet duct 21, so that the airflow from the input end of the air inlet duct 21 can make full contact with the evaporator 40, thereby ensuring the evaporator 40's efficiency in cooling and condensing moisture in the humid air.

[0035] Furthermore, the condenser 50 is located at the inlet of the air outlet duct 23, so that the dry and cold airflow output from the dehumidification duct 22 can undergo sufficient heat exchange through the condenser 50.

[0036] Furthermore, the evaporator 40 is provided with a water collection tank 41, which is located on the bottom side of the evaporator 40 and installed at the bottom of the dehumidification pipe 22 to collect condensate generated on the surface of the evaporator 40. Specifically, in one embodiment, the evaporator 40 is also provided with a drain pump 42, which is located on the bottom side of the water collection tank 41 and installed at the bottom wall of the dehumidification pipe 22. The input end of the drain pump 42 is connected to the bottom wall of the water collection tank 41 to pump and discharge condensate from the water collection tank 41.

[0037] Furthermore, the air outlet duct 23 is provided with a guide grille 231, which is installed at the output end of the air outlet duct 23 to guide the output dry air.

[0038] In summary, the dehumidifier disclosed in this utility model uses a frame as the main body to support the compressor and the air duct structure, ensuring overall mechanical strength. Furthermore, by independently mounting the compressor in the second mounting section, physically separating it from the first mounting section which includes the fan and heat exchanger, the compressor's vibration is prevented from being directly transmitted to the casing and air duct system. This fundamentally reduces additional noise and structural fatigue caused by resonance. Simultaneously, the combination of the frame and casing not only facilitates assembly but also provides a robust skeleton for the relatively thin casing, ensuring the stability of the air duct shape and preventing abnormal airflow under high air pressure. Firstly, the connection structure of the air inlet duct, dehumidification duct, and air outlet duct forms a continuous, undisturbed U-shaped, L-shaped, or Z-shaped flow channel, which can effectively reduce airflow resistance, allowing more air to be delivered under the same fan power, thus improving heat exchange efficiency. Secondly, the independent setting of the first and second installation parts makes the core functional components relatively independent, greatly improving maintenance convenience. Furthermore, by arranging the dehumidification duct along the height of the frame and placing the air inlet and outlet at the top and bottom respectively, the vertical space is fully utilized, making the overall structure very compact and occupying a small area.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
