Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on and claims the benefit of priority from Chinese Patent Application No. 2025205502756, No. 2025205504802, and No. 2025205504499, filed on 26 Mar. 2025, the entireties of these applications are incorporated by reference herein.TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of household appliances, and in particular, to an ultra-thin dehumidifier.BACKGROUND

[0003] When air comes into contact with an object that has a relatively low surface temperature, moisture in the air condenses into water droplets on the surface of the object. During the operation of a refrigeration system, the temperature of an evaporator decreases while the temperature of a condenser increases. After the machine is started, indoor air is drawn in and first passes through the evaporator, causing the moisture in the air to condense on the surface of the evaporator and drip into a water tank, thereby achieving a dehumidification effect.

[0004] For dehumidifiers that utilize the above-mentioned refrigeration system, the housing is typically a cuboid in shape and needs to accommodate components such as a compressor, condenser, throttling element, evaporator and fan. This results in a relatively large thickness of the housing, making it difficult to meet the requirements of certain household usage scenarios and containerized transportation. Therefore, there is a demand for thinner dehumidifier.

[0005] Especially for the requirements of containerized transportation, assuming that the dimensions of the compressor in a dehumidifier remain unchanged, calculations show that when the length, width and height of the dehumidifier body is optimized to, for example, 145 mm×280 mm×400 mm, the number of dehumidifiers that can be loaded in a standard container is maximized. However, existing compressor-based dehumidifier solutions on the market cannot achieve the ultra-thickness of 145 mm mentioned above. If the dimensions of the fan, condenser and evaporator are forcibly reduced to meet this ultra-thin requirement, the dehumidification capacity will be diminished. Therefore, a better solution is needed to reduce the thickness of the whole dehumidifier without diminishing dehumidification capacity.SUMMARY

[0006] To overcome the shortcomings of existing technologies, one of the objectives of the present disclosure is to provide an ultra-thin dehumidifier with reduced thickness while maintaining undiminished dehumidification capacity.

For example, they may be a fixed connection, or a detachable connection, or an integrated connection, may be a mechanical connection or an electric connection, may be a direct connection or an indirect connection through an intermediation, or may be an internal connection between two elements. Those of ordinary skill in the art can determine the specific meanings of the above words in the present disclosure in a rational way in combination with the specific contents of the technical solutions.

[0053] Referring to FIG. 1 to FIG. 7, FIG. 8 to FIG. 13, or FIG. 14 to FIG. 16, an ultra-thin dehumidifier of the present disclosure includes a housing 100. The length direction of the housing 100 is a first direction, the width direction of the housing 100 is a second direction, and the height direction of the housing 100 is a third direction. An evaporator-condenser assembly 500 and a fan 600 are disposed in the housing 100. The evaporator-condenser assembly 500 includes an evaporator 510 and a condenser 520 arranged at an interval along the first direction. Each of the evaporator 510 and the condenser 520 has its length direction arranged in the second direction, has its width direction arranged in the first direction, and has its height direction arranged in the third direction. The fan 600 is configured to drive external airflow to pass through the evaporator 510 and the condenser 520 in sequence. The evaporator-condenser assembly 500 is provided with a continuous extension portion or a discontinuous extension portion for increasing the ventilation area thereof.

[0054] For the ultra-thin dehumidifier of the above structure, the length direction of the evaporator 510 and the condenser 520 is arranged along the width direction of the housing 100, the height direction of the evaporator 510 and the condenser 520 is arranged along the height direction of the housing 100, and the continuous extension portion or the discontinuous extension portion is used to increase the ventilation area of the evaporator-condenser assembly 500. Therefore, when the housing 100 is designed to have a reduced width dimension, the heat exchange areas of the evaporator 510 and the condenser 520 can be maintained or even increased, thereby ensuring undiminished dehumidification capacity, while meeting the requirements for placement in limited spaces and for packaging and transportation.

[0055] Referring to FIG. 2 to FIG. 6, in some embodiments of the present disclosure, the internal space of the housing 100 is divided into an upper region 110 and a lower region 120. A compressor 300 and a water collection box 400 are disposed in lower region 120. The evaporator 510 and the condenser 520 are located in the upper region 110. An extension segment 530 is provided at each of the lower ends of the evaporator 510 and the condenser 520. The extension segments 530 form the continuous extension portion. The extension segments 530 extend in the upper region 110 along the first direction, or the extension segments 530 extend downward into the lower region 120 along the third direction.

[0056] The upper end of the compressor 300 is the boundary that divides the upper region 110 and the lower region 120. The compressor 300 and the water collection box 400 are disposed in the lower region 120. The evaporator 510, the condenser 520, and the fan 600 are sequentially disposed in the upper region 110. An extension segment 530 is provided at each of the lower ends of the evaporator 510 and the condenser 520 to increase the ventilation area, and the extension segments 530 can selectively extend along the first direction or the third direction based on the layout space, thereby making full use of the internal space of the housing 100. Therefore, when the housing 100 is designed to have a reduced width dimension, the heat exchange efficiency can be improved as much as possible while maintaining undiminished dehumidification capacity. This is also suitable for situations where the placement space for the dehumidifier is limited, and reduces packaging and transportation costs.

[0057] It should be noted that, in the present embodiment, the housing 100 is a regular cuboid, and the first direction, second direction, and third direction correspond to the length, width, and height of the housing 100, respectively. Of course, in other embodiments, when the housing 100 is in an irregular shape or an ellipsoidal shape, the requirements of the above solution can be still be met as long as the housing 100 has distinct longitudinal, lateral, and height dimensions.

[0058] Referring to FIG. 2 or FIG. 3, in some embodiments of the present disclosure, the evaporator 510, the condenser 520, and the fan 600 are sequentially arranged at intervals. The extension segment 530 of the evaporator 510 and the extension segment 530 of the condenser 520 both extend along the first direction. The extension segment 530 of the condenser 520 is at least partially located directly above the extension segment 530 of the evaporator 510. The housing 100 is provided with an air inlet 101 facing the evaporator 510. After entering from the air inlet 101, external airflow can pass through all areas of the evaporator 510 and the condenser 520. It should be appreciated that when the fan 600 drives external airflow to pass through the evaporator 510, the airflow is cooled and liquefied into water droplets, which are received by the water collection box 400. The cooled airflow passes through the condenser 520 to form a dry air with a relatively high temperature, which is then discharged into an indoor environment. The extension segment 530 of the condenser 520 is at least partially located directly above the extension segment 530 of the evaporator 510. In other words, the extension segment 530 of the condenser 520 and the extension segment 530 of the evaporator 510 at least partially overlap in the height direction. In addition, the evaporator 510, the condenser 520, and the fan 600 are sequentially arranged at intervals. This helps to minimize the length dimension of the housing 100 to the maximum extent, thereby further reducing the volume of the dehumidifier. After entering from the air inlet 101, the external airflow can pass through all areas of the evaporator 510 and the condenser 520, thereby ensuring effective heat exchange of the air and further ensuring dehumidification efficiency.

[0059] Referring to FIG. 2 or FIG. 3, in some embodiments of the present disclosure, the fan 600 is at least partially located directly above the extension segment 530 of the condenser 520. In other words, the fan 600 and the extension segment 530 of the condenser 520 at least partially overlap in the height direction. This helps to further reduce the length dimension of the housing 100, resulting in smaller length and width dimensions of the dehumidifier, thereby further reducing the volume of the dehumidifier.

[0060] Referring to FIG. 2 or FIG. 4, in some embodiments of the present disclosure, a height space is provided between the upper end of the compressor 300 and the extension segment 530 of the evaporator 510, an air inlet side of the fan 600 faces the extension segment 530 of the condenser 520, and the projection of the air inlet 101 along the first direction covers all areas of the evaporator 510. It should be noted that if the airflow only flows along the first direction through the extension segments 530 of the evaporator 510 and the condenser 520, it may lead to excessive air resistance and insufficient heat exchange. The air inlet side of the fan 600 faces the extension segment 530 of the condenser 520, such that after passing through the height space, the airflow can pass through the extension segments 530 of the evaporator 510 and the condenser 520 along the thickness direction of the extension segments 530. This helps the airflow to fully contact all areas of the extension segments 530 of the evaporator 510 and the condenser 520. The projection of the air inlet 101 along the first direction covers all areas of evaporator 510, which helps to ensure that the drawn air can exchange heat with all areas of the evaporator 510 and the condenser 520.

[0061] Referring to FIG. 4, FIG. 5 or FIG. 6, in some embodiments of the present disclosure, the compressor 300 and the water collection box 400 are arranged at an interval along the first direction. The evaporator-condenser assembly 500 is located directly above the water collection box 400. The extension segments 530 of the evaporator 510 and the condenser 520 both extend downward into the lower region 120. The housing 100 is provided with an air inlet 101 facing the evaporator 510, and the projection of the air inlet 101 along the first direction covers all areas of the evaporator-condenser assembly 500. It should be appreciated that as the extension segments 530 extend downward, the evaporator 510 and the extension segment 530 above the evaporator 510 form a rectangular body with a small thickness, and the condenser 520 and the extension segment 530 on the condenser 520 form a rectangular body with a small thickness. The air inlet 101 completely covers the projected areas of the evaporator 510 and the condenser 520 along the first direction. When the fan 600 is working, it drives external airflow to enter from the air inlet 101 and pass through the evaporator 510 and the condenser 520 along the thickness direction thereof, enhancing air heat exchange, thereby improving dehumidification efficiency.

[0062] Referring to FIG. 8, FIG. 9 and FIG. 16, in some embodiments of the present disclosure, a compressor 300 is provided in the housing 100, and at least a portion of the internal space of the housing 100 located outside the compressor 300 forms an air duct cavity 140. The housing 100 is provided with an air inlet 101 and an air outlet 102 which are in communication with the air duct cavity 140. The evaporator 510 and the condenser 520 are both located in the air duct cavity 140, and the lower ends of the evaporator 510 and the condenser 520 both extend to one side of the compressor 300 along the third direction to form the continuous extension portion.

[0063] At least a portion of the internal space of the housing 100 located outside the compressor 300 is used to form an air duct cavity 140, and the evaporator 510, the condenser 520, and the fan 600 are accommodated in the air duct cavity 140. There is no need to provide a water tank 800 in the housing 100, such that the lower ends of the evaporator 510 and the condenser 520 can extend to one side of the compressor 300. When the housing 100 is designed to have a reduced width dimension, the heat exchange areas of the evaporator 510 and the condenser 520 can be maintained or even increased, thereby ensuring undiminished capacity, while meeting the requirements for placement in limited spaces and for packaging and transportation.

[0064] Referring to FIG. 9 or FIG. 11, in some embodiments of the present disclosure, the air inlet 101 is provided on each of two side walls of the housing 100 along the first direction. The compressor 300 is disposed at a central portion of the bottom of the housing 100. An evaporator-condenser assembly 500 is provided on each of two sides of the compressor 300. Each of the two evaporators 510 faces each of the two air inlets 101, respectively. The fan 600 is located between the two condensers 520. The air outlet 102 is provided on one side wall of the housing 100 along the second direction or on a top wall of the housing 100 along the third direction.

[0065] It should be appreciated that two evaporator-condenser assemblies 500 are symmetrically arranged along the first direction on both sides of the compressor 300. When the fan 600 is working, a negative pressure is formed between the two condensers 520, drawing external airflow through the two air inlets 101. The air then sequentially passes through the corresponding evaporators 510 and condensers 520 before being discharged from the housing 100 through the air outlet 102. Only one fan 600 is needed, resulting in a simple structure and low costs. Due to the increased quantities of evaporators 510 and condensers 520, the dehumidification capacity can be maintained unchanged or even increased when the housing 100 is designed to have a reduced width dimension, thereby meeting the requirements for placement in limited spaces and for packaging and transportation.

[0066] Referring to FIG. 8 and FIG. 9, in some embodiments of the present disclosure, the air outlet 102 is provided on the top wall of the housing 100, and the output shaft of a motor 610 of the fan 600 is arranged vertically upward. The fan 600 drives the airflow below and on both sides thereof to be discharged upward through the air outlet 102, thereby preventing direct airflow impingement on the human body and enhancing comfort.

[0067] Referring to FIG. 10 and FIG. 11, in some embodiments of the present disclosure, the air outlet 102 is provided on the front side wall of the housing 100 along the second direction. The output shaft of the motor 610 of the fan 600 is arranged along the second direction. A guide end plate 630 is disposed on the side of the fan 600 adjacent to a back side of the housing 100, and a guide tube 640 is disposed on the side of the fan 600 facing the air outlet 102. After passing through the two condensers 520 on both sides of the fan 600, air enters the fan 600 and is directed by the guide end plate 630 toward the guide tube 640, thereby preventing airflow disorder and excessive air turbulence.

[0068] In some embodiments of the present disclosure, a water receiving tray 210 is disposed on each of two sides of the compressor 300, at a lower portion of the air duct cavity 140. Each of the two water receiving trays 210 is located above each of the two evaporators 510, respectively. The water receiving trays 210 are connected to a drainage unit 700 for discharging condensed water in the water receiving trays 210. It should be appreciated that external airflow contacts the evaporators 510 to form condensed water, which then drips into the water receiving trays 210. The drainage unit 700 may be connected to a water tank 800 or transfer the condensed water to a preset destination through the pipe 720.

[0069] Specifically, a U-shaped arched plate 220 with an opening facing downward is connected between the two water receiving trays 210. The fan 600 is located directly above the arched plate 220. The arched plate 220 has arc guide surfaces bent toward the central axis thereof, at two sides of an upper portion thereof. Air entering through the two air inlets 101 can converge at the input end of the fan 600 along the arc guide surfaces. The arched plate 220 and the bottom surface of the housing 100 define an accommodating cavity 130 for accommodating the compressor 300. Air entering through the two air inlets 101 can flow upward along the two arc guide surfaces to reach the top of the arched plate 220 and then be drawn in by the fan 600 disposed above the arched plate 220, which helps to reduce wind noise and improve airflow efficiency.

[0070] Referring to FIG. 11 and FIG. 12, in some embodiments of the present disclosure, the drainage unit 700 includes a water pump 710 and a pipe 720 connected to the water pump 710. The input end of the pipe 720 extends into the water receiving trays 210, and the output end of the pipe 720 is disposed at a top portion on the back side of the housing 100. The back side of the housing 100 is detachably attached to a water tank 800. A water inlet pipe 810 connected to the output end of the pipe 720 in a sealing manner is provided on a wall panel of the water tank 800 adjacent to the housing 100.

[0071] The externally mounted water tank 800 eliminates the need to occupy the internal space of the housing 100, allowing the size of the housing 100 of the dehumidifier to be designed smaller along the second direction. When the water tank 800 is attached to the back side of the housing 100, the water inlet pipe 810 is in communication with the pipe 720 of the housing 100, and users can also choose to connect or not connect the water tank 800 as actually needed.

[0072] Referring to FIG. 12, in some embodiments of the present disclosure, the water tank 800 has a receiving cavity with an upper opening. The ultra-thin dehumidifier has an idle state and a working state. In the idle state, the receiving cavity of the water tank 800 at least receives a portion of the housing 100, while in the working state, the receiving cavity of the water tank 800 is configured to store condensed water generated during a dehumidification process. This not only helps to reduce the occupied space of the dehumidifier when it is idle, saving storage space or transportation space, but also enables the water tank 800 to serve a dual purpose by functioning as a condensed water reservoir.

[0073] Referring to FIG. 13, in some embodiments of the present disclosure, one evaporator-condenser assembly 500 is provided. The air inlet 101 is provided on one side wall of the housing 100 along the first direction. An arc-shaped guide plate 230 that bends upward in the direction away from the air inlet 101 is disposed at a lower portion of the air duct cavity 140. The compressor 300 is located below the arc-shaped guide plate 230. The evaporator-condenser assembly 500 is located at the downslope of the arc-shaped guide plate 230, and the fan 600 is located at the upslope of the arc-shaped guide plate 230. It should be appreciated that when the fan 600 is working, external airflow enters horizontally through the air inlet 101, and after passing through the evaporator-condenser assembly 500, the air flows upward along the arc-shaped guide plate 230 and is then drawn into the input end of the fan 600. The arc-shaped guide plate 230 can reduce noise and ensures smooth airflow.

[0074] Referring to FIG. 9 or FIG. 11, in some embodiments of the present disclosure, the length dimensions of the evaporator 510 and the condenser 520 are consistent with the width dimension of the housing 100, and the height dimensions of the evaporator 510 and the condenser 520 match with the height dimension of the housing 100. The above dimension configuration for the evaporator 510 and the condenser 520 fully utilizes the width and height space of the housing 100, which helps to improve heat exchange efficiency, thereby enhancing dehumidification performance.

[0075] Referring to FIG. 14 to FIG. 16, in some embodiments of the present disclosure, the internal space of the housing 100 is divided into an upper region 110 and a lower region 120. A compressor 300 and a water collection box 400 are disposed in the lower region 120. N evaporator-condenser assemblies 500 are disposed in the upper region 110, where N is a positive integer greater than or equal to 2. Among them, (N−1) evaporator-condenser assemblies 500 form a discontinuous extension portion of the remaining evaporator-condenser assembly 500. The fan 600 drives external airflow to pass through the evaporators 510 and the corresponding condensers 520.

[0076] The dehumidifier is provided with at least two evaporator-condenser assemblies 500 along the first direction in the upper region 110, and the fan 600 can drive air to sequentially pass through the evaporator 510 and the condenser 520 of each evaporator-condenser assembly 500. Due to the increased quantities of evaporators 510 and condensers 520, the dehumidification capacity can be maintained unchanged or even increased when the housing 100 is designed to have a reduced width dimension, thereby meeting the requirements for placement in limited spaces and for packaging and transportation. Furthermore, the internal space of the housing 100 is fully utilized, improving the structural compactness of the dehumidifier.

[0077] The housing 100 is a regular cuboid, and the first direction, the second direction, and the third direction correspond to the length, width, and height of the housing 100, respectively. Of course, in other embodiments, when the housing 100 is in an irregular shape or an ellipsoidal shape, the requirements of the above solution can still be met as long as the housing 100 has distinct longitudinal, lateral, and height dimensions.

[0078] Referring to FIG. 14 or FIG. 15, in some embodiments of the present disclosure, an air inlet 101 is provided at each of two ends of the housing 100 in the length direction. Two evaporator-condenser assemblies 500 are provided. Each of the two evaporators 510 faces each of the two air inlets 101, respectively. The fan 600 is located between the two condensers 520. An air outlet 102 is provided on one side wall of the housing 100 along the second direction or on the top wall of the housing 100. The fan 600 can drive external airflow to enter from the two air inlets 101 respectively and then be discharged from the air outlet 102. It should be appreciated that when the fan 600 is working, a negative pressure is formed in the area between the two condensers 520. Part of external airflow enters from one of the air inlets 101, passes through one of the evaporators 510 and one of the condensers 520, and is drawn into the air inlet side of the fan 600. Part of external airflow enters through the other air inlet 101, passes through the other evaporator 510 and the other condenser 520, and is drawn into the air inlet side of the fan 600. A single fan 600 is sufficient to discharge air from the air outlet 102 of the housing 100, resulting in a simple structure and low costs.

[0079] Referring to FIG. 14, in some embodiments of the present disclosure, the air outlet 102 is provided on the top wall of the housing 100, and the output end of the fan 600 is vertically upward, thereby preventing direct airflow impingement on the human body and enhancing comfort. A water receiving tray 210 is provided in the housing 100 and is located below the two evaporator-condenser assemblies 500. An air inlet cavity in communication with the input end of the fan 600 is defined between the water receiving tray 210 and the two condensers 520.

[0080] Referring to FIG. 14, in some embodiments of the present disclosure, an upwardly extending mounting sleeve 240 is formed at a central portion of the water receiving tray 210. The fan 600 includes a motor 610 disposed within the mounting sleeve 240 and a first blade 620 connected to the motor 610. A guide end plate 630 is disposed on the air inlet side of the first blade 620, and a guide tube 640 facing the air outlet 102 is disposed on the air outlet side of the first blade 620. Specifically, the motor 610 is fixedly mounted within the mounting sleeve 240, and the output shaft of the motor 610 extends upward. The first blade 620 drives air in the air inlet cavity to be discharged upward. The guide end plate 630 directs air flowing along both sides of the first blade 620 through the two condensers 520 into the first blade 620, and then the air is discharged upward from the guide tube 640 to the air outlet 102, thereby preventing excessive air turbulence.

[0081] Referring to FIG. 15, in some embodiments of the present disclosure, the air outlet 102 is provided on one side wall of the housing 100 along the second direction. The water receiving tray 210, the housing 100, and the two condensers 520 together define an air inlet cavity. The input end of the fan 600 is located in the air inlet cavity, and the output end of the fan 600 faces the air outlet 102. Specifically, the fan 600 draws air on both sides thereof through the two condensers 520 into the fan 600, and then the air is discharged from the air outlet 102 along the second direction.

[0082] It should be noted that the fan 600 may be connected and fixed to the top, side or bottom of the upper region 110 of the housing 100 by means of a support structure. The fan 600 may be an axial flow fan 600, a cross-flow fan 600, a centrifugal fan 600, or any other type of fan 600 that can generate negative pressure at the air outlet 102. An axial flow fan 600, a cross-flow fan 600, and a centrifugal fan 600 can all generate suction during operation to drive external airflow to pass through the evaporators 510 and the condensers 520 and reach the input end of the fan 600. The output end of the fan 600 may be selectively disposed on the top wall or one side wall of the housing 100, depending on the type of the fan 600. Preferably, the fan 600 is configured as an axial flow fan 600. The entire structure of an axial flow fan 600 is relatively simple and linearly arranged, thereby offering simplified installation and space-efficient deployment. Furthermore, an axial flow fan 600 can generate a high flow rate at relatively low speeds, which helps to accelerate the dehumidification rate.

[0083] Referring to FIG. 14 or FIG. 15, in some embodiments of the present disclosure, a mounting gap 900 is formed between the condensers 520 and the adjacent evaporators 510, and between the fan 600 and the two condensers 520. The mounting gap 900 is greater than or equal to 8 mm. It should be noted that when the fan 600 drives external airflow to pass through the evaporator 510 of each evaporator-condenser assembly 500, the airflow is cooled and liquefied into water droplets, which are received by the water collection box 400. The cooled airflow passes through the condensers 520 to form a dry air with a relatively high temperature, which is then discharged into an indoor environment. The mounting gaps 900 reduce the weakening effect of the heat from the condensers 520 on the cooling capacity of the evaporators 510, thereby ensuring the dehumidification effect. The mounting gaps 900 also prevent the heat from the condensers 520 being directly transferred to the fan 600, which may easily cause overheating. However, an excessively large mounting gap 900 may result in an oversized length dimension of the housing 100. After testing, it has been found that a mounting gap 900 slightly larger than 8 mm can adequately meet operational requirements.

[0084] To prevent the liquefied water droplets from being reheated by the condensers 520 to generate water vapor, which could affect the working efficiency of the dehumidifier, the water receiving tray 210 is in communication with the water collection box 400.

[0085] Referring to FIG. 14 or FIG. 15, in some embodiments of the present disclosure, one of the evaporator-condenser assemblies 500 is located directly above the water collection box 400. A recessed shell 250 is provided at one side of the water receiving tray 210 and is located between the water collection box 400 and the corresponding evaporator-condenser assembly 500. The recessed shell 250 is located below a partition to form a stepped structure, and the lower ends of the corresponding evaporator 510 and condenser 520 extend into the recessed shell 250. It should be appreciated that the recessed shell 250 occupies a portion of the space in the lower region 120, such that the evaporator 510 and condenser 520 of the corresponding evaporator-condenser assembly 500 can be designed to have larger height dimensions, which helps to improve heat exchange efficiency. Meanwhile, the positional relationship between the recessed shell 250 and the water collection box 400 avoids interference with the compressor 300.

[0086] In some embodiments of the present disclosure, the housing 100 has a width dimension along the second direction between 130 mm and 190 mm. Based on actual production measurements, for the dehumidifier of any of the above technical solutions, the width dimension of the housing 100 can be limited to between 130 mm and 190 mm, maintaining the dehumidification capacity unchanged, while meeting the requirements for placement in limited spaces and for packaging and transportation. Preferably, the width dimension of the housing 100 is 145 mm, which maximizes the number of dehumidifiers that can be loaded in a standard container.

[0087] The technical features of the above embodiments may be combined in any manner. To make the description concise, 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.

[0088] Although the embodiments of the present disclosure have been shown and described, it should be appreciated by those of ordinary skills in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and gist of the present disclosure, the scope of which is defined by the claims and their equivalents.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is based on and claims the benefit of priority from Chinese Patent Application No. 2025205502756, No. 2025205504802, and No. 2025205504499, filed on 26 Mar. 2025, the entireties of these applications are incorporated by reference herein.TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of household appliances, and in particular, to an ultra-thin dehumidifier.BACKGROUND

[0003] When air comes into contact with an object that has a relatively low surface temperature, moisture in the air condenses into water droplets on the surface of the object. During the operation of a refrigeration system, the temperature of an evaporator decreases while the temperature of a condenser increases. After the machine is started, indoor air is drawn in and first passes through the evaporator, causing the moisture in the air to condense on the surface of the evaporator and drip into a water tank, thereby achieving a dehumidification effect.

[0004] For dehumidifiers that utilize the above-mentioned refrigeration system, the housing is typically a cuboid in shape and needs to accommodate components such as a compressor, condenser, throttling element, evaporator and fan. This results in a relatively large thickness of the housing, making it difficult to meet the requirements of certain household usage scenarios and containerized transportation. Therefore, there is a demand for thinner dehumidifier.

[0005] Especially for the requirements of containerized transportation, assuming that the dimensions of the compressor in a dehumidifier remain unchanged, calculations show that when the length, width and height of the dehumidifier body is optimized to, for example, 145 mm×280 mm×400 mm, the number of dehumidifiers that can be loaded in a standard container is maximized. However, existing compressor-based dehumidifier solutions on the market cannot achieve the ultra-thickness of 145 mm mentioned above. If the dimensions of the fan, condenser and evaporator are forcibly reduced to meet this ultra-thin requirement, the dehumidification capacity will be diminished. Therefore, a better solution is needed to reduce the thickness of the whole dehumidifier without diminishing dehumidification capacity.SUMMARY

[0006] To overcome the shortcomings of existing technologies, one of the objectives of the present disclosure is to provide an ultra-thin dehumidifier with reduced thickness while maintaining undiminished dehumidification capacity.

[0053] Referring to FIG. 1 to FIG. 7, FIG. 8 to FIG. 13, or FIG. 14 to FIG. 16, an ultra-thin dehumidifier of the present disclosure includes a housing 100. The length direction of the housing 100 is a first direction, the width direction of the housing 100 is a second direction, and the height direction of the housing 100 is a third direction. An evaporator-condenser assembly 500 and a fan 600 are disposed in the housing 100. The evaporator-condenser assembly 500 includes an evaporator 510 and a condenser 520 arranged at an interval along the first direction. Each of the evaporator 510 and the condenser 520 has its length direction arranged in the second direction, has its width direction arranged in the first direction, and has its height direction arranged in the third direction. The fan 600 is configured to drive external airflow to pass through the evaporator 510 and the condenser 520 in sequence. The evaporator-condenser assembly 500 is provided with a continuous extension portion or a discontinuous extension portion for increasing the ventilation area thereof.

[0054] For the ultra-thin dehumidifier of the above structure, the length direction of the evaporator 510 and the condenser 520 is arranged along the width direction of the housing 100, the height direction of the evaporator 510 and the condenser 520 is arranged along the height direction of the housing 100, and the continuous extension portion or the discontinuous extension portion is used to increase the ventilation area of the evaporator-condenser assembly 500. Therefore, when the housing 100 is designed to have a reduced width dimension, the heat exchange areas of the evaporator 510 and the condenser 520 can be maintained or even increased, thereby ensuring undiminished dehumidification capacity, while meeting the requirements for placement in limited spaces and for packaging and transportation.

[0055] Referring to FIG. 2 to FIG. 6, in some embodiments of the present disclosure, the internal space of the housing 100 is divided into an upper region 110 and a lower region 120. A compressor 300 and a water collection box 400 are disposed in lower region 120. The evaporator 510 and the condenser 520 are located in the upper region 110. An extension segment 530 is provided at each of the lower ends of the evaporator 510 and the condenser 520. The extension segments 530 form the continuous extension portion. The extension segments 530 extend in the upper region 110 along the first direction, or the extension segments 530 extend downward into the lower region 120 along the third direction.

[0056] The upper end of the compressor 300 is the boundary that divides the upper region 110 and the lower region 120. The compressor 300 and the water collection box 400 are disposed in the lower region 120. The evaporator 510, the condenser 520, and the fan 600 are sequentially disposed in the upper region 110. An extension segment 530 is provided at each of the lower ends of the evaporator 510 and the condenser 520 to increase the ventilation area, and the extension segments 530 can selectively extend along the first direction or the third direction based on the layout space, thereby making full use of the internal space of the housing 100. Therefore, when the housing 100 is designed to have a reduced width dimension, the heat exchange efficiency can be improved as much as possible while maintaining undiminished dehumidification capacity. This is also suitable for situations where the placement space for the dehumidifier is limited, and reduces packaging and transportation costs.

[0057] It should be noted that, in the present embodiment, the housing 100 is a regular cuboid, and the first direction, second direction, and third direction correspond to the length, width, and height of the housing 100, respectively. Of course, in other embodiments, when the housing 100 is in an irregular shape or an ellipsoidal shape, the requirements of the above solution can be still be met as long as the housing 100 has distinct longitudinal, lateral, and height dimensions.

[0058] Referring to FIG. 2 or FIG. 3, in some embodiments of the present disclosure, the evaporator 510, the condenser 520, and the fan 600 are sequentially arranged at intervals. The extension segment 530 of the evaporator 510 and the extension segment 530 of the condenser 520 both extend along the first direction. The extension segment 530 of the condenser 520 is at least partially located directly above the extension segment 530 of the evaporator 510. The housing 100 is provided with an air inlet 101 facing the evaporator 510. After entering from the air inlet 101, external airflow can pass through all areas of the evaporator 510 and the condenser 520. It should be appreciated that when the fan 600 drives external airflow to pass through the evaporator 510, the airflow is cooled and liquefied into water droplets, which are received by the water collection box 400. The cooled airflow passes through the condenser 520 to form a dry air with a relatively high temperature, which is then discharged into an indoor environment. The extension segment 530 of the condenser 520 is at least partially located directly above the extension segment 530 of the evaporator 510. In other words, the extension segment 530 of the condenser 520 and the extension segment 530 of the evaporator 510 at least partially overlap in the height direction. In addition, the evaporator 510, the condenser 520, and the fan 600 are sequentially arranged at intervals. This helps to minimize the length dimension of the housing 100 to the maximum extent, thereby further reducing the volume of the dehumidifier. After entering from the air inlet 101, the external airflow can pass through all areas of the evaporator 510 and the condenser 520, thereby ensuring effective heat exchange of the air and further ensuring dehumidification efficiency.

[0059] Referring to FIG. 2 or FIG. 3, in some embodiments of the present disclosure, the fan 600 is at least partially located directly above the extension segment 530 of the condenser 520. In other words, the fan 600 and the extension segment 530 of the condenser 520 at least partially overlap in the height direction. This helps to further reduce the length dimension of the housing 100, resulting in smaller length and width dimensions of the dehumidifier, thereby further reducing the volume of the dehumidifier.

[0060] Referring to FIG. 2 or FIG. 4, in some embodiments of the present disclosure, a height space is provided between the upper end of the compressor 300 and the extension segment 530 of the evaporator 510, an air inlet side of the fan 600 faces the extension segment 530 of the condenser 520, and the projection of the air inlet 101 along the first direction covers all areas of the evaporator 510. It should be noted that if the airflow only flows along the first direction through the extension segments 530 of the evaporator 510 and the condenser 520, it may lead to excessive air resistance and insufficient heat exchange. The air inlet side of the fan 600 faces the extension segment 530 of the condenser 520, such that after passing through the height space, the airflow can pass through the extension segments 530 of the evaporator 510 and the condenser 520 along the thickness direction of the extension segments 530. This helps the airflow to fully contact all areas of the extension segments 530 of the evaporator 510 and the condenser 520. The projection of the air inlet 101 along the first direction covers all areas of evaporator 510, which helps to ensure that the drawn air can exchange heat with all areas of the evaporator 510 and the condenser 520.

[0061] Referring to FIG. 4, FIG. 5 or FIG. 6, in some embodiments of the present disclosure, the compressor 300 and the water collection box 400 are arranged at an interval along the first direction. The evaporator-condenser assembly 500 is located directly above the water collection box 400. The extension segments 530 of the evaporator 510 and the condenser 520 both extend downward into the lower region 120. The housing 100 is provided with an air inlet 101 facing the evaporator 510, and the projection of the air inlet 101 along the first direction covers all areas of the evaporator-condenser assembly 500. It should be appreciated that as the extension segments 530 extend downward, the evaporator 510 and the extension segment 530 above the evaporator 510 form a rectangular body with a small thickness, and the condenser 520 and the extension segment 530 on the condenser 520 form a rectangular body with a small thickness. The air inlet 101 completely covers the projected areas of the evaporator 510 and the condenser 520 along the first direction. When the fan 600 is working, it drives external airflow to enter from the air inlet 101 and pass through the evaporator 510 and the condenser 520 along the thickness direction thereof, enhancing air heat exchange, thereby improving dehumidification efficiency.

[0062] Referring to FIG. 8, FIG. 9 and FIG. 16, in some embodiments of the present disclosure, a compressor 300 is provided in the housing 100, and at least a portion of the internal space of the housing 100 located outside the compressor 300 forms an air duct cavity 140. The housing 100 is provided with an air inlet 101 and an air outlet 102 which are in communication with the air duct cavity 140. The evaporator 510 and the condenser 520 are both located in the air duct cavity 140, and the lower ends of the evaporator 510 and the condenser 520 both extend to one side of the compressor 300 along the third direction to form the continuous extension portion.

[0063] At least a portion of the internal space of the housing 100 located outside the compressor 300 is used to form an air duct cavity 140, and the evaporator 510, the condenser 520, and the fan 600 are accommodated in the air duct cavity 140. There is no need to provide a water tank 800 in the housing 100, such that the lower ends of the evaporator 510 and the condenser 520 can extend to one side of the compressor 300. When the housing 100 is designed to have a reduced width dimension, the heat exchange areas of the evaporator 510 and the condenser 520 can be maintained or even increased, thereby ensuring undiminished capacity, while meeting the requirements for placement in limited spaces and for packaging and transportation.

[0064] Referring to FIG. 9 or FIG. 11, in some embodiments of the present disclosure, the air inlet 101 is provided on each of two side walls of the housing 100 along the first direction. The compressor 300 is disposed at a central portion of the bottom of the housing 100. An evaporator-condenser assembly 500 is provided on each of two sides of the compressor 300. Each of the two evaporators 510 faces each of the two air inlets 101, respectively. The fan 600 is located between the two condensers 520. The air outlet 102 is provided on one side wall of the housing 100 along the second direction or on a top wall of the housing 100 along the third direction.

[0065] It should be appreciated that two evaporator-condenser assemblies 500 are symmetrically arranged along the first direction on both sides of the compressor 300. When the fan 600 is working, a negative pressure is formed between the two condensers 520, drawing external airflow through the two air inlets 101. The air then sequentially passes through the corresponding evaporators 510 and condensers 520 before being discharged from the housing 100 through the air outlet 102. Only one fan 600 is needed, resulting in a simple structure and low costs. Due to the increased quantities of evaporators 510 and condensers 520, the dehumidification capacity can be maintained unchanged or even increased when the housing 100 is designed to have a reduced width dimension, thereby meeting the requirements for placement in limited spaces and for packaging and transportation.

[0066] Referring to FIG. 8 and FIG. 9, in some embodiments of the present disclosure, the air outlet 102 is provided on the top wall of the housing 100, and the output shaft of a motor 610 of the fan 600 is arranged vertically upward. The fan 600 drives the airflow below and on both sides thereof to be discharged upward through the air outlet 102, thereby preventing direct airflow impingement on the human body and enhancing comfort.

[0067] Referring to FIG. 10 and FIG. 11, in some embodiments of the present disclosure, the air outlet 102 is provided on the front side wall of the housing 100 along the second direction. The output shaft of the motor 610 of the fan 600 is arranged along the second direction. A guide end plate 630 is disposed on the side of the fan 600 adjacent to a back side of the housing 100, and a guide tube 640 is disposed on the side of the fan 600 facing the air outlet 102. After passing through the two condensers 520 on both sides of the fan 600, air enters the fan 600 and is directed by the guide end plate 630 toward the guide tube 640, thereby preventing airflow disorder and excessive air turbulence.

[0068] In some embodiments of the present disclosure, a water receiving tray 210 is disposed on each of two sides of the compressor 300, at a lower portion of the air duct cavity 140. Each of the two water receiving trays 210 is located above each of the two evaporators 510, respectively. The water receiving trays 210 are connected to a drainage unit 700 for discharging condensed water in the water receiving trays 210. It should be appreciated that external airflow contacts the evaporators 510 to form condensed water, which then drips into the water receiving trays 210. The drainage unit 700 may be connected to a water tank 800 or transfer the condensed water to a preset destination through the pipe 720.

[0069] Specifically, a U-shaped arched plate 220 with an opening facing downward is connected between the two water receiving trays 210. The fan 600 is located directly above the arched plate 220. The arched plate 220 has arc guide surfaces bent toward the central axis thereof, at two sides of an upper portion thereof. Air entering through the two air inlets 101 can converge at the input end of the fan 600 along the arc guide surfaces. The arched plate 220 and the bottom surface of the housing 100 define an accommodating cavity 130 for accommodating the compressor 300. Air entering through the two air inlets 101 can flow upward along the two arc guide surfaces to reach the top of the arched plate 220 and then be drawn in by the fan 600 disposed above the arched plate 220, which helps to reduce wind noise and improve airflow efficiency.

[0070] Referring to FIG. 11 and FIG. 12, in some embodiments of the present disclosure, the drainage unit 700 includes a water pump 710 and a pipe 720 connected to the water pump 710. The input end of the pipe 720 extends into the water receiving trays 210, and the output end of the pipe 720 is disposed at a top portion on the back side of the housing 100. The back side of the housing 100 is detachably attached to a water tank 800. A water inlet pipe 810 connected to the output end of the pipe 720 in a sealing manner is provided on a wall panel of the water tank 800 adjacent to the housing 100.

[0071] The externally mounted water tank 800 eliminates the need to occupy the internal space of the housing 100, allowing the size of the housing 100 of the dehumidifier to be designed smaller along the second direction. When the water tank 800 is attached to the back side of the housing 100, the water inlet pipe 810 is in communication with the pipe 720 of the housing 100, and users can also choose to connect or not connect the water tank 800 as actually needed.

[0072] Referring to FIG. 12, in some embodiments of the present disclosure, the water tank 800 has a receiving cavity with an upper opening. The ultra-thin dehumidifier has an idle state and a working state. In the idle state, the receiving cavity of the water tank 800 at least receives a portion of the housing 100, while in the working state, the receiving cavity of the water tank 800 is configured to store condensed water generated during a dehumidification process. This not only helps to reduce the occupied space of the dehumidifier when it is idle, saving storage space or transportation space, but also enables the water tank 800 to serve a dual purpose by functioning as a condensed water reservoir.

[0073] Referring to FIG. 13, in some embodiments of the present disclosure, one evaporator-condenser assembly 500 is provided. The air inlet 101 is provided on one side wall of the housing 100 along the first direction. An arc-shaped guide plate 230 that bends upward in the direction away from the air inlet 101 is disposed at a lower portion of the air duct cavity 140. The compressor 300 is located below the arc-shaped guide plate 230. The evaporator-condenser assembly 500 is located at the downslope of the arc-shaped guide plate 230, and the fan 600 is located at the upslope of the arc-shaped guide plate 230. It should be appreciated that when the fan 600 is working, external airflow enters horizontally through the air inlet 101, and after passing through the evaporator-condenser assembly 500, the air flows upward along the arc-shaped guide plate 230 and is then drawn into the input end of the fan 600. The arc-shaped guide plate 230 can reduce noise and ensures smooth airflow.

[0074] Referring to FIG. 9 or FIG. 11, in some embodiments of the present disclosure, the length dimensions of the evaporator 510 and the condenser 520 are consistent with the width dimension of the housing 100, and the height dimensions of the evaporator 510 and the condenser 520 match with the height dimension of the housing 100. The above dimension configuration for the evaporator 510 and the condenser 520 fully utilizes the width and height space of the housing 100, which helps to improve heat exchange efficiency, thereby enhancing dehumidification performance.

[0075] Referring to FIG. 14 to FIG. 16, in some embodiments of the present disclosure, the internal space of the housing 100 is divided into an upper region 110 and a lower region 120. A compressor 300 and a water collection box 400 are disposed in the lower region 120. N evaporator-condenser assemblies 500 are disposed in the upper region 110, where N is a positive integer greater than or equal to 2. Among them, (N−1) evaporator-condenser assemblies 500 form a discontinuous extension portion of the remaining evaporator-condenser assembly 500. The fan 600 drives external airflow to pass through the evaporators 510 and the corresponding condensers 520.

[0076] The dehumidifier is provided with at least two evaporator-condenser assemblies 500 along the first direction in the upper region 110, and the fan 600 can drive air to sequentially pass through the evaporator 510 and the condenser 520 of each evaporator-condenser assembly 500. Due to the increased quantities of evaporators 510 and condensers 520, the dehumidification capacity can be maintained unchanged or even increased when the housing 100 is designed to have a reduced width dimension, thereby meeting the requirements for placement in limited spaces and for packaging and transportation. Furthermore, the internal space of the housing 100 is fully utilized, improving the structural compactness of the dehumidifier.

[0077] The housing 100 is a regular cuboid, and the first direction, the second direction, and the third direction correspond to the length, width, and height of the housing 100, respectively. Of course, in other embodiments, when the housing 100 is in an irregular shape or an ellipsoidal shape, the requirements of the above solution can still be met as long as the housing 100 has distinct longitudinal, lateral, and height dimensions.

[0078] Referring to FIG. 14 or FIG. 15, in some embodiments of the present disclosure, an air inlet 101 is provided at each of two ends of the housing 100 in the length direction. Two evaporator-condenser assemblies 500 are provided. Each of the two evaporators 510 faces each of the two air inlets 101, respectively. The fan 600 is located between the two condensers 520. An air outlet 102 is provided on one side wall of the housing 100 along the second direction or on the top wall of the housing 100. The fan 600 can drive external airflow to enter from the two air inlets 101 respectively and then be discharged from the air outlet 102. It should be appreciated that when the fan 600 is working, a negative pressure is formed in the area between the two condensers 520. Part of external airflow enters from one of the air inlets 101, passes through one of the evaporators 510 and one of the condensers 520, and is drawn into the air inlet side of the fan 600. Part of external airflow enters through the other air inlet 101, passes through the other evaporator 510 and the other condenser 520, and is drawn into the air inlet side of the fan 600. A single fan 600 is sufficient to discharge air from the air outlet 102 of the housing 100, resulting in a simple structure and low costs.

[0079] Referring to FIG. 14, in some embodiments of the present disclosure, the air outlet 102 is provided on the top wall of the housing 100, and the output end of the fan 600 is vertically upward, thereby preventing direct airflow impingement on the human body and enhancing comfort. A water receiving tray 210 is provided in the housing 100 and is located below the two evaporator-condenser assemblies 500. An air inlet cavity in communication with the input end of the fan 600 is defined between the water receiving tray 210 and the two condensers 520.

[0080] Referring to FIG. 14, in some embodiments of the present disclosure, an upwardly extending mounting sleeve 240 is formed at a central portion of the water receiving tray 210. The fan 600 includes a motor 610 disposed within the mounting sleeve 240 and a first blade 620 connected to the motor 610. A guide end plate 630 is disposed on the air inlet side of the first blade 620, and a guide tube 640 facing the air outlet 102 is disposed on the air outlet side of the first blade 620. Specifically, the motor 610 is fixedly mounted within the mounting sleeve 240, and the output shaft of the motor 610 extends upward. The first blade 620 drives air in the air inlet cavity to be discharged upward. The guide end plate 630 directs air flowing along both sides of the first blade 620 through the two condensers 520 into the first blade 620, and then the air is discharged upward from the guide tube 640 to the air outlet 102, thereby preventing excessive air turbulence.

[0081] Referring to FIG. 15, in some embodiments of the present disclosure, the air outlet 102 is provided on one side wall of the housing 100 along the second direction. The water receiving tray 210, the housing 100, and the two condensers 520 together define an air inlet cavity. The input end of the fan 600 is located in the air inlet cavity, and the output end of the fan 600 faces the air outlet 102. Specifically, the fan 600 draws air on both sides thereof through the two condensers 520 into the fan 600, and then the air is discharged from the air outlet 102 along the second direction.

[0082] It should be noted that the fan 600 may be connected and fixed to the top, side or bottom of the upper region 110 of the housing 100 by means of a support structure. The fan 600 may be an axial flow fan 600, a cross-flow fan 600, a centrifugal fan 600, or any other type of fan 600 that can generate negative pressure at the air outlet 102. An axial flow fan 600, a cross-flow fan 600, and a centrifugal fan 600 can all generate suction during operation to drive external airflow to pass through the evaporators 510 and the condensers 520 and reach the input end of the fan 600. The output end of the fan 600 may be selectively disposed on the top wall or one side wall of the housing 100, depending on the type of the fan 600. Preferably, the fan 600 is configured as an axial flow fan 600. The entire structure of an axial flow fan 600 is relatively simple and linearly arranged, thereby offering simplified installation and space-efficient deployment. Furthermore, an axial flow fan 600 can generate a high flow rate at relatively low speeds, which helps to accelerate the dehumidification rate.

[0083] Referring to FIG. 14 or FIG. 15, in some embodiments of the present disclosure, a mounting gap 900 is formed between the condensers 520 and the adjacent evaporators 510, and between the fan 600 and the two condensers 520. The mounting gap 900 is greater than or equal to 8 mm. It should be noted that when the fan 600 drives external airflow to pass through the evaporator 510 of each evaporator-condenser assembly 500, the airflow is cooled and liquefied into water droplets, which are received by the water collection box 400. The cooled airflow passes through the condensers 520 to form a dry air with a relatively high temperature, which is then discharged into an indoor environment. The mounting gaps 900 reduce the weakening effect of the heat from the condensers 520 on the cooling capacity of the evaporators 510, thereby ensuring the dehumidification effect. The mounting gaps 900 also prevent the heat from the condensers 520 being directly transferred to the fan 600, which may easily cause overheating. However, an excessively large mounting gap 900 may result in an oversized length dimension of the housing 100. After testing, it has been found that a mounting gap 900 slightly larger than 8 mm can adequately meet operational requirements.

[0084] To prevent the liquefied water droplets from being reheated by the condensers 520 to generate water vapor, which could affect the working efficiency of the dehumidifier, the water receiving tray 210 is in communication with the water collection box 400.

[0085] Referring to FIG. 14 or FIG. 15, in some embodiments of the present disclosure, one of the evaporator-condenser assemblies 500 is located directly above the water collection box 400. A recessed shell 250 is provided at one side of the water receiving tray 210 and is located between the water collection box 400 and the corresponding evaporator-condenser assembly 500. The recessed shell 250 is located below a partition to form a stepped structure, and the lower ends of the corresponding evaporator 510 and condenser 520 extend into the recessed shell 250. It should be appreciated that the recessed shell 250 occupies a portion of the space in the lower region 120, such that the evaporator 510 and condenser 520 of the corresponding evaporator-condenser assembly 500 can be designed to have larger height dimensions, which helps to improve heat exchange efficiency. Meanwhile, the positional relationship between the recessed shell 250 and the water collection box 400 avoids interference with the compressor 300.

[0086] In some embodiments of the present disclosure, the housing 100 has a width dimension along the second direction between 130 mm and 190 mm. Based on actual production measurements, for the dehumidifier of any of the above technical solutions, the width dimension of the housing 100 can be limited to between 130 mm and 190 mm, maintaining the dehumidification capacity unchanged, while meeting the requirements for placement in limited spaces and for packaging and transportation. Preferably, the width dimension of the housing 100 is 145 mm, which maximizes the number of dehumidifiers that can be loaded in a standard container.

[0087] The technical features of the above embodiments may be combined in any manner. To make the description concise, 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.

[0088] Although the embodiments of the present disclosure have been shown and described, it should be appreciated by those of ordinary skills in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and gist of the present disclosure, the scope of which is defined by the claims and their equivalents.
