Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to an ultra-thin dehumidification device. Background Technology
[0002] When air encounters an object with a low surface temperature, water droplets condense on that object's surface. During the operation of a refrigeration system, the evaporator temperature decreases while the condenser temperature increases. After the machine starts, it draws in indoor air, which first passes through the evaporator, causing the water vapor in the air to condense on the evaporator surface and drip into the water tank, thus achieving the dehumidification function.
[0003] For dehumidifiers utilizing the aforementioned refrigeration system, the dehumidifier casing is typically rectangular. The casing needs to house the compressor, condenser, throttling element, evaporator, water tank, and fan, resulting in a relatively thick casing. This makes it difficult to meet the requirements of some household applications and container shipping. Especially for container shipping, calculations show that when the dehumidifier's dimensions (length, width, and height) reach a certain size (e.g., 145mm*280mm*400mm), a large number of dehumidifiers can fit into a standard shipping container. However, current solutions cannot achieve the extremely thin thickness of 145mm mentioned above. Forcibly reducing the size of the fan, condenser, and evaporator to achieve this thinness would reduce dehumidification capacity. Therefore, a better solution is needed to reduce the overall thickness of the machine without compromising performance. Utility Model Content

[0032] Reference Figure 1 , Figure 2 and Figure 7 The present invention discloses an ultra-thin dehumidification device, comprising: a housing 100, wherein the length direction, width direction, and height direction of the housing 100 are respectively a first direction, a second direction, and a third direction; a compressor 300 is disposed inside the housing 100; the portion of the internal space of the housing 100 below the horizontal plane where the top of the compressor 300 is located is the lower region; the portion of the internal space of the housing 100 above the horizontal plane where the top of the compressor 300 is located is the upper region; at least a portion of the internal space of the housing 100 outside the compressor 300 constitutes an air duct cavity 200; at least one set of two-electrode assemblies 400 is disposed inside the air duct cavity 200; the two-electrode assembly 400 includes an evaporator 410 and a condenser 420 arranged at intervals along the first direction.
[0033] Furthermore, the two-device assembly 400 is provided with a continuous extension portion or an intermittent extension portion for increasing the ventilation area of the two-device assembly 400.
[0034] As one specific embodiment of the discontinuous extension portion, and not a limitation thereof, the discontinuous extension portion includes at least another pair of device components 400 arranged along the first direction.
[0035] As one specific embodiment of the continuous extension portion, and not a limitation thereof, the lower end of the two-device assembly has an extension segment that extends along the first direction in the upper region, or the extension segment extends downward along the third direction into the lower region.
[0036] Specifically, the lower ends of the evaporator 410 and the condenser 420 both extend along the third direction to the side of the compressor 300. The housing 100 is provided with an air inlet 101 and an air outlet 102 that communicate with the air duct cavity 200. The air duct cavity 200 is provided with a fan device 500 that drives external gas to pass sequentially through the air inlet 101, the evaporator 410, the corresponding condenser 420, and the air outlet 102.
[0037] The housing 100 of the ultra-thin dehumidifier described above has at least a portion of its internal space outside the compressor 300 forming an air duct cavity 200. The air duct cavity 200 houses the evaporator 410, condenser 420, and fan unit 500, eliminating the need for a water tank 700 inside the housing 100. This allows the lower ends of the evaporator 410 and condenser 420 to extend to the side of the compressor 300. By designing a smaller width dimension for the housing 100, the heat exchange area of the evaporator 410 and condenser 420 can be maintained or increased, thereby ensuring that the dehumidification capacity is not reduced and meeting the requirements of a small placement area and packaging and transportation.
[0038] See Figure 2 or Figure 4 In some embodiments of this utility model, the housing 100 is provided with air inlets 101 on both side walls along the first direction, the compressor 300 is located at the middle position of the bottom of the housing 100, a set of two-evapor assembly 400 is provided on both sides of the compressor 300, the two evaporators 410 are respectively facing the two air inlets 101, the fan device 500 is located between the two condensers 420, and the air outlet 102 is provided on the side wall of the housing 100 along the second direction or along the top wall of the third direction.
[0039] Understandably, along the first direction, two sets of two-phase evaporator assemblies 400 are symmetrically arranged on both sides of the compressor 300. When the fan unit 500 is working, it creates a negative pressure between the two condensers 420, driving external gas to enter through the two air inlets 101, pass sequentially through the corresponding evaporators 410 and condensers 420, and then exit from the outlet 102 outside the casing 100. Only one fan unit 500 is needed, resulting in a simple structure and low cost. Due to the increased number of evaporators 410 and condensers 420, the dehumidification capacity can be maintained or increased while designing a smaller width for the casing 100, thus meeting the requirements of a smaller placement space and packaging and transportation.
[0040] See Figure 1 and Figure 2 In some embodiments of this utility model, the air outlet 102 is located on the top wall of the housing 100. The fan device 500 includes a first motor 510 and a first fan blade 520 connected to the first motor 510. The output shaft of the first motor 510 is vertically upward. The first fan blade 520 drives the airflow below and on both sides to be discharged upward to the air outlet 102, avoiding direct blowing on the human body and improving comfort.
[0041] See Figure 3 and Figure 4In some embodiments of this utility model, the air outlet 102 is located on the front sidewall of the housing 100 along the second direction. The fan device 500 includes a second motor 530 located on the back of the housing 100 and a second fan blade 540 connected to the second motor 530. The output shaft of the second motor 530 is arranged along the second direction. A guide plate 550 is provided on the side of the second fan blade 540 near the back of the housing 100, and a guide tube 560 is provided on the side of the second fan blade 540 facing the air outlet 102. Specifically, when the second motor 530 drives the second fan blade 540, the gas enters the second fan blade 540 after passing through the two condensers 420 on both sides of the second fan blade 540. Under the guidance of the guide plate 550, the gas flows towards the guide tube 560, avoiding gas turbulence and excessive flow.
[0042] In some embodiments of this utility model, a water collection tray 220 is provided on each side of the compressor 300 at the lower part of the air duct cavity 200. The two water collection trays 220 are respectively located above the two evaporators 410. The water collection trays 220 are connected to a drainage unit for draining the condensate in the water collection trays 220. It can be understood that external gas comes into contact with the evaporator 410 and forms condensate, which drips into the water collection trays 220. The drainage unit can be connected to a water tank or transferred to a preset destination through a pipeline.
[0043] Specifically, a U-shaped arched plate with an opening facing downwards is connected between the two water receiving trays 220. The fan device 500 is located directly above the arched plate 210. The upper two sides of the arched plate 210 have arc-shaped guide surfaces that curve towards its central axis. Gas entering from the two air inlets 101 can converge along the arc-shaped guide surfaces to the input end of the fan device 500. The arched plate 210 and the bottom surface of the housing 100 form a cavity 110 for accommodating the compressor 300. Gas entering from the two air inlets 101 can climb upwards along the two arc-shaped guide surfaces to the top of the arched plate 210 and be drawn in by the fan device 500 above the arched plate 210, which helps to reduce wind noise and improve gas intake and exhaust efficiency.
[0044] See Figure 4 and Figure 5 In some embodiments of this utility model, the drainage unit includes a water pump 610 and a pipe 620 connected to the water pump 610. The input end of the pipe 620 extends into the water receiving tray 220, and the output end of the pipe 620 is located at the top of the back of the housing 100. A water tank 700 is detachably attached to the back of the housing 100. The water tank 700 has an inlet pipe 710 that is sealed and connected to the output end of the pipe 620 on the wall panel near the housing 100.
[0045] By using an external water tank 700, the internal space of the housing 100 is not occupied, allowing the housing 100 of the dehumidifier to be designed to be smaller in the second direction. When the water tank 700 is attached to the back of the housing 100, the water inlet pipe 710 is connected to the pipe 620 of the housing 100. Users can also choose to connect or not connect the water tank 700 according to their actual needs.
[0046] In some embodiments, the bottom of the housing 100 is placed directly on a water tank with the opening of the water tank facing the bottom of the housing 100. A through hole is provided through the water receiving tray 220 and the bottom plate of the housing 100, so that condensate can drip into the water tank along the through hole. This also achieves the purpose of making the housing 100 of the dehumidification device smaller in the second direction by placing the water tank externally.
[0047] In some embodiments of this utility model, the water tank 700 has a receiving cavity with an opening at the top. The ultra-thin dehumidifier has an idle state and an operating state. In the idle state, the receiving cavity of the water tank 700 accommodates at least a portion of the shell 100. In the operating state, the receiving cavity of the water tank 700 is used to store condensate generated during the dehumidification process. This not only helps to reduce the floor space occupied by the ultra-thin dehumidifier when it is idle, reducing storage or transportation space, but also achieves the function of storing condensate, thus achieving a dual-purpose effect for the water tank 700.
[0048] See Figure 1 , Figure 2 and Figure 7 In some embodiments of this utility model, the evaporator 410 and the condenser 420 extend along the second direction, and their lengths are consistent with the width of the housing 100. The evaporator 410 and the condenser 420 also extend along the third direction, and their heights match the height of the housing 100. This structure of the evaporator 410 and condenser 420 fully utilizes the width and height of the housing 100, which is beneficial for improving heat exchange efficiency and dehumidification performance. Preferably, the projection of the air inlet 101 along the first direction covers the entire position of the evaporator 410, which helps ensure that the gas can exchange heat with all positions of the evaporator 410 and condenser 420 when it is drawn in.
[0049] See Figure 6In some embodiments of this utility model, the two-component assembly 400 is configured as a group, the air inlet 101 is located on one side wall of the housing 100 along the first direction, the lower part of the air duct cavity 200 is provided with an arc-shaped guide plate 250 that curves upward in a direction away from the air inlet 101, the compressor 300 is located below the arc-shaped guide plate 250, and the two-component assembly 400 and the fan device 500 are respectively located at the lower slope and upper slope of the arc-shaped guide plate 250. It can be understood that when the fan device 500 is working, external gas enters horizontally from the air inlet 101, passes through the two-component assembly 400, climbs upward along the arc-shaped guide plate 250, and is drawn into the input end of the fan device 500. The arc-shaped guide plate 250 can reduce noise and allow the gas to flow smoothly.
[0050] In some embodiments of this utility model, the width of the housing 100 along the second direction is between 130mm and 190mm. Actual production calculations show that the dehumidifier with the above-described structural layout can limit the width of the housing 100 to between 130mm and 190mm, meeting the requirements of a smaller placement area and packaging / transportation while maintaining the same dehumidification capacity. Preferably, when the width of the housing 100 is 145mm, it is advantageous to fit a larger number of dehumidifiers into a standard shipping container.
[0051] 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.
[0052] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
