[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 11 This embodiment provides a dehumidifier 10. The dehumidifier 10 includes a dehumidifier body 100, a support frame 200, and an air guide assembly 300. The dehumidifier body 100 is the core structure of the dehumidifier 10, and internally houses components such as a compressor, heat exchanger, and fan, used to dehumidify the intake air and generate dry, hot air. The support frame 200 is disposed on the dehumidifier body 100 and used to support items to be dried. The air guide assembly 300 is movably disposed on the dehumidifier body 100 to guide the hot air generated by the dehumidifier body 100 to the external environment or the items to be dried on the support frame 200.

[0033] Specifically, the dehumidifier body 100 typically has a casing 110, with an air inlet and an air outlet 112. A fan drives outside air to enter through the air inlet, where it is dehumidified and becomes dry, hot air, which is then discharged through the air outlet 112. A shelf 200 can be installed on the top, side, or other suitable location of the casing 110, and can take the form of a hook, bracket, or wire basket. For example, the shelf 200 can be a hanging rod for hanging clothes or a mesh rack for placing shoes. Users can place or hang shoes, clothes, towels, and other items to be dried on the shelf 200 according to their actual drying needs, allowing the dehumidifier 10 to adapt to the drying needs of different types of items and expanding its application scenarios.

[0034] Regarding the air guide shroud assembly 300, it is "movably disposed" on the dehumidifier body 100. In this embodiment, the position of the air guide shroud assembly 300 relative to the dehumidifier body 100 is changeable. By changing the position of the air guide shroud assembly 300, the direction of airflow can be changed. When the air guide shroud assembly 300 is in the first position, the hot air generated by the dehumidifier body 100 is directed to the external environment. At this time, the dehumidifier 10 mainly performs the conventional dehumidification function to reduce the indoor air humidity. When the air guide shroud assembly 300 is in the second position, the hot air generated by the dehumidifier body 100 is directed to the item support rack 200 and concentrated on the items to be dried placed on the item support rack 200. At this time, the dehumidifier 10 performs the drying function, using hot air to quickly remove moisture from the surface of the items.

[0035] It should be understood that the "movable" connection between the air guide shroud assembly 300 and the dehumidifier body 100 can be implemented in various ways, as long as the position of the air guide shroud assembly 300 relative to the dehumidifier body 100 can be changed. As a preferred embodiment, the air guide shroud assembly 300 can be rotatably connected to the dehumidifier body 100. For example, the air guide shroud assembly 300 can be rotatably connected to the air outlet 112 of the dehumidifier body 100 via a hinge, shaft, or other structure. The user can switch between a first position and a second position by rotating the air guide shroud assembly 300 around its axis of rotation using a knob or by directly turning it. This rotatable connection method is simple in structure, convenient to operate, and ensures the structural strength of the connection point.

[0036] As an alternative implementation, the air guide shroud assembly 300 can also be slidably connected to the dehumidifier body 100. For example, a slide rail or slide groove can be provided on the dehumidifier body 100, and a corresponding slider can be provided on the air guide shroud assembly 300. The air guide shroud assembly 300 slides within the slide rail via the slider, thereby achieving position changes of extending (guiding items) or retracting (guiding the outside). This sliding connection method allows for smoother movement of the air guide shroud assembly 300 and facilitates adjustment of the air guiding distance.

[0037] As another alternative implementation, the air guide shroud assembly 300 can also be mounted on the dehumidifier body 100 via a snap-fit ​​mechanism. For example, the air guide shroud assembly 300 can be detachably snapped into slots at different heights or angles on the dehumidifier body 100 via a snap-fit ​​structure, or it can be suspended at any angle via a damping hinge. These connection methods all fall under the specific manifestation of "movably mounted" and are all within the scope of protection of this application. Through the above-mentioned various movable connection methods, the air guide shroud assembly 300 can flexibly change the air outlet direction, allowing the dehumidifier 10 to freely switch between dehumidification mode and drying mode, greatly improving the user experience.

[0038] Thus, by incorporating a support rack 200 on the dehumidifier body 100, the dehumidifier 10 allows users to directly place clothing, shoes, and other items to be dried on the dehumidifier 10 for drying, eliminating the need for separate drying equipment. This effectively expands the functionality of the dehumidifier 10 and enhances its practicality and efficiency. Furthermore, by adding a movable air guide assembly 300 to the dehumidifier body 100, the dehumidifier 10 allows users to flexibly adjust the direction of hot airflow according to actual needs: when dehumidification is required, the air guide assembly 300 can be directed towards the external environment to allow hot air to escape normally; when drying items is required, the air guide assembly 300 can be adjusted to face the support rack 200, concentrating the hot air onto the items to be dried, thereby significantly improving drying efficiency and user experience.

[0039] In some embodiments, the dehumidifier body 100 is provided with an air outlet 112 for discharging the dehumidified hot air from inside the dehumidifier body 100. The air guide shroud assembly 300 includes an air guide shroud 310 and an air guide baffle 320. The air guide shroud 310 is movably disposed on the dehumidifier body 100 to be in a first position or a second position. The air guide shroud 310 is provided with a first air guide opening 115. The air guide baffle 320 is movably disposed on the air guide shroud 310 to open or close the first air guide opening 115.

[0040] The dehumidifier 10 has a first working state and a second working state. For example... Figure 1 As shown, when the dehumidifier 10 is in its first operating state, the air guide baffle 320 opens the first air guide port 115, the air guide hood 310 is in its first position, and the air outlet 112, the first air guide port 115, and the external environment are connected in sequence. At this time, the hot air generated by the dehumidifier body 100 is discharged through the air outlet 112 and flows directly to the external environment through the open first air guide port 115, realizing the conventional indoor dehumidification function. This direct-venting airflow design has low wind resistance, which helps to improve dehumidification efficiency.

[0041] like Figure 2 and Figure 3As shown, when the dehumidifier 10 is in its second operating state, the air guide baffle 320 closes the first air guide port 115, the air guide shroud 310 is in its second position, and the dehumidifier body 100 and the air guide shroud 310 cooperate to form the second air guide port 116. The air outlet 112, the second air guide port 116, and the external environment are connected in sequence to guide the airflow to the items to be dried on the item support rack 200. In this state, the first air guide port 115, which originally served as the main exhaust channel, is closed by the air guide baffle 320, forcing the airflow to find a new outlet. At this time, a temporary or specific air duct gap is constructed between the air guide shroud 310 and the outer wall of the dehumidifier body 100, namely the second air guide port 116. According to the principles of fluid dynamics, airflow will flow to the area of ​​lower pressure after being obstructed. The design of the second air guide port 116 utilizes this principle to force hot air to the preset area—that is, the location of the item support rack 200. This design cleverly utilizes the interrelationships between structural components, enabling airflow switching without the need for additional complex piping structures, thus reducing production costs.

[0042] Regarding the movement of the air guide baffle 320, in a preferred embodiment, the air guide baffle 320 can be hinged to the air guide cover 310, and can be opened and closed manually by the user or driven by a motor. In another embodiment, the air guide baffle 320 can also be slidably connected to the air guide cover 310. By providing a groove on the air guide cover 310, the air guide baffle 320 slides along the groove to cover or expose the first air guide opening 115. Furthermore, the air guide baffle 320 can also adopt an elastic flap structure, automatically opening when the airflow pressure reaches a certain threshold, or closing by gravity or elasticity when there is no pressure. All these specific movement methods should be covered within the scope of protection of this application.

[0043] In this embodiment, the opening and closing of the first air vent 115 is controlled by the air guide baffle 320, and the position of the air guide hood 310 is changed, enabling the dehumidifier 10 to flexibly switch between normal dehumidification mode and item drying mode. In particular, the formation mechanism of the second air vent 116, through the dynamic cooperation between the air guide hood 310 and the dehumidifier body 100, precisely guides hot air to the item support rack 200, significantly improving drying efficiency and solving the problem of poor drying effect caused by hot air diffusion in the prior art.

[0044] In other embodiments, the air guide baffle 320 and the air guide cover 310 are partially stacked, and the air guide baffle 320 and the air guide cover 310 are slidably engaged, thereby making the air guide baffle 320 and the air guide cover 310 fit together more tightly.

[0045] In some embodiments, the air guide shroud 310 is rotatably connected to the dehumidifier body 100, so that the air guide shroud 310 is in a first position or a second position. Rotary connection is a simple and reliable mechanical connection method, enabling angular changes of the air guide shroud 310 relative to the dehumidifier body 100. Specifically, one of the air guide shroud 310 and the dehumidifier body 100 is provided with a rotating shaft structure 311, and the other with a rotating groove structure 101, with the rotating shaft structure 311 and the rotating groove structure 101 rotatably engaged. For example, cylindrical rotating shafts can be provided on both sides of the air guide shroud 310, and a rotating groove with a notch can be provided at the edge of the air outlet 112 of the dehumidifier body 100, with the rotating shaft embedded in the rotating groove and able to rotate relative to it. This shaft-hole engagement method has low processing costs and smooth rotation. It should be understood that, in addition to shaft-hole engagement, hinge connections, pin connections, etc., can also be used, as long as the air guide shroud 310 can rotate relative to the dehumidifier body 100 on a fixed axis; these are all within the scope of protection of this application.

[0046] Please see Figure 8 and Figure 11 To ensure the stability of the air guide shroud 310 in the first or second position and to prevent accidental displacement due to wind or machine vibration, the dehumidifier 10 also includes an elastic locking mechanism 400. The elastic locking mechanism 400 is installed on the dehumidifier body 100. When the air guide shroud 310 is in the first or second position, the elastic locking mechanism 400 can lock into the air guide shroud 310. Specifically, the elastic locking mechanism 400 includes a mounting base, a locking ball, and an elastic element. The mounting base has a mounting groove with an opening. A portion of the locking ball is disposed within the mounting groove, and the other portion protrudes outside the opening. The elastic element is installed within the mounting groove and abuts against the bottom of the groove and the locking ball. The elastic element is preferably a spring, which consistently applies an elastic force to the locking ball in the direction of the opening. Correspondingly, the air guide cover 310 is provided with a first groove 312 and a second groove 313. When the air guide cover 310 is in the first position, the locking ball is locked in place with the first groove 312; when the air guide cover 310 is in the second position, the locking ball is locked in place with the second groove 313. Its working principle is as follows: when the user rotates the air guide cover 310, the inner wall of the air guide cover 310 will squeeze the locking ball, forcing the locking ball to compress the elastic element and retract into the mounting groove. At this time, the air guide cover 310 can rotate smoothly. When the air guide cover 310 rotates to the first or second position, the first groove 312 or the second groove 313 rotates exactly to the position of the locking ball. Under the restoring force of the elastic element, the locking ball pops out and locks into the corresponding groove, forming a positioning. This "elastic locking" structural design not only provides the user with a clear "click" tactile feedback to confirm that the air guide cover 310 is in place, but also effectively locks the position of the air guide cover 310, ensuring the stability of the working state.

[0047] Please see Figure 3 and Figure 4 Furthermore, to prevent excessive rotation of the air guide shroud 310 and damage to its internal structure, one of the air guide shroud 310 and the dehumidifier 10 is provided with a stop 102, and the other with a stop groove 314. When the air guide shroud 310 is in the first or second position, the stop 102 engages with the groove wall of the stop groove 314. The stop 102 can be a protrusion or a pin, and the stop groove 314 is a groove with a specific arc length. Preferably, the extension path of the stop groove 314 is consistent with the rotation path of the air guide shroud 310. This means that the stop groove 314 extends along the arc direction of the rotation of the air guide shroud 310. When the air guide shroud 310 rotates, the stop 102 slides within the stop groove 314. When the air guide shroud 310 reaches its limit position (i.e., the first or second position), the stop 102 will strike the end wall of the stop groove 314, thereby preventing the air guide shroud 310 from continuing to rotate. This limiting structure can effectively protect the rotating shaft structure 311 and the locking mechanism, extending the product's service life.

[0048] Regarding the position of the air guide shroud 310, when the air guide shroud 310 is in the first or second position, part of the dehumidifier body 100 is located inside the air guide shroud 310. This design allows the air guide shroud 310 to partially cover the air outlet 112 area of ​​the dehumidifier body 100 when it is in storage or working state, which not only makes the overall appearance more compact and beautiful, but also plays a role in dust prevention and protection of the air outlet 112 to a certain extent. At the same time, the item support frame 200 is located below the air guide shroud 310; when the dehumidifier 10 is in the second working state, the second air guide vent 116 faces the item support frame 200. Since hot air has a lower density and an upward tendency, placing the second air guide vent 116 above and facing the item support frame 200 below can utilize the sinking effect of hot air or direct blowing to allow the hot air to come into full contact with the items to be dried, improve the heat energy utilization rate, and thus significantly improve the drying efficiency.

[0049] Please see Figure 5 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the dehumidifier body 100 includes a housing 110, a dehumidifier main body 120, and multiple filter components. The housing 110 is provided with a receiving space 111, an air outlet 112, and multiple air inlets. The air outlet 112 and the multiple air inlets are all connected to the receiving space 111. The dehumidifier main body 120 and the multiple filter components are all disposed within the receiving space 111. Each filter component corresponds to one air inlet. The dehumidifier main body 120 drives air to flow in from the air inlet. The air first passes through the corresponding filter component and then flows out from the air outlet 112.

[0050] Specifically, the outer casing 110 serves as the supporting frame of the dehumidifier 10, and the internal accommodating space 111 is used to install various functional components. The air outlet 112 is used to discharge the treated dry, hot air, while multiple air inlets are used to introduce humid external air. In this embodiment, the number of air inlets is two or more, and correspondingly, the number of filter components matches the number of air inlets. This structural design of "one air inlet for each filter component" has significant technical advantages. First, from a fluid dynamics perspective, setting multiple air inlets significantly increases the total air intake area compared to the traditional single air inlet structure. With a fixed fan power, a larger air intake area means lower air intake resistance, thereby allowing for the intake of more air and improving the working efficiency of the dehumidifier 10. Second, from an air purification perspective, this one-to-one correspondence constructs independent filtration channels. When external air enters the accommodating space 111, it must be filtered by the filter component corresponding to its respective air inlet. This structure forces airflow to pass through a filter, effectively preventing unfiltered air from entering the containment space 111 directly through the gaps (i.e., the "airflow short-circuit" phenomenon), thus ensuring that all air participating in the dehumidification cycle is purified and improving the quality of the air output.

[0051] It should be understood that although this embodiment focuses on describing the one-to-one correspondence between the air inlet and the filter assembly, in actual product design, the layout of the air inlet and the filter assembly can take many forms. For example, the air inlets can be respectively set on opposite sides of the housing 110 to form opposing air intake; or they can be set on adjacent sides of the housing 110 to form tangential air intake. The corresponding filter assembly can be a HEPA filter, an activated carbon filter, or a composite filter, etc., and its shape is adapted to the shape of the air inlet, such as rectangular, circular, or annular. Through this combination of multi-channel air intake and multi-stage filtration, the dehumidifier 10 achieves efficient removal of particulate matter and odors in the air while ensuring large-volume dehumidification, meeting users' high standards for air quality.

[0052] This application distributes the filtration task across multiple filter components at the air inlets. This distributed filtration structure effectively reduces the load on individual filters, significantly slowing down dust accumulation and lowering the risk of clogging. Therefore, users do not need to frequently clean or replace filters, extending the equipment's maintenance cycle and improving ease of use.

[0053] Furthermore, since the air undergoes preliminary filtration through its respective filter components before entering the dehumidifier body 120, the increased air resistance caused by filter blockage at the air outlet 112 is avoided. This helps maintain stable and unobstructed airflow channels, ensuring that the dehumidifier body 120 (such as the fan and evaporator) operates efficiently under its design conditions. This not only increases the overall airflow output but also reduces the additional energy consumption caused by increased air resistance, achieving energy saving and consumption reduction.

[0054] Furthermore, by installing multiple independent filter components on the air inlet side, large particles of dust, hair, and other contaminants can be effectively prevented from entering the dehumidifier body 120, protecting core components (such as the compressor 123, heat exchanger, and fan) from contamination or wear. This not only enhances the stability of equipment operation but also extends the service life of the entire unit and reduces the failure rate.

[0055] Please see Figure 2 and Figure 3 In some embodiments, the multiple air inlets include a first air inlet 113 and a second air inlet 114, which are located on the sides of the housing 110 and on opposite sides of the housing 110. This symmetrical layout design has significant hydrodynamic advantages. When the fan assembly 122 is operating, airflow enters simultaneously from opposite sides of the housing 110, creating a countercurrent or converging effect. Compared to single-sided air intake, this dual-sided air intake effectively balances the air pressure distribution inside the housing 110, reducing eddies and aerodynamic noise caused by strong airflow on one side. Simultaneously, the design of the air inlets on opposite sides increases the air intake area, reduces the air intake velocity, further reduces wind resistance, and improves the operating efficiency of the dehumidifier 10.

[0056] Regarding the stacking layout of the internal components, the dehumidifier body 120 includes a dehumidification module 121, a fan assembly 122, and a compressor 123, with the dehumidification module 121 and compressor 123 connected via refrigerant piping. Multiple filter components include a first filter assembly 131 and a second filter assembly 132, which are sequentially arranged between the first air inlet 113 and the second air inlet 114. This layout creates a continuous airflow channel. Air entering from the first air inlet 113 undergoes preliminary filtration by the first filter assembly 131 to remove large particles, then is dehumidified by the dehumidification module 121, subsequently pressurized and transported by the fan assembly 122, and finally flows out from the air outlet 112. Air flowing into the second air inlet 114 is first filtered by the second filter assembly 132 before flowing out from the air outlet 112.

[0057] In some embodiments, the dehumidification module 121 is the core component of the dehumidifier 10 for achieving air dehumidification. It typically consists of an evaporator, a condenser, a throttling device, and connecting pipes, and forms a complete refrigeration cycle system with the compressor 123 through refrigerant pipes. In the dehumidifier 10 of this application, the dehumidification module 121 is installed in the receiving space 111 inside the outer casing 110, located upstream of the fan assembly 122 or at a key position in the airflow path, ensuring that the humid air entering from the air inlet can fully flow through its heat exchange surface to complete the process of moisture condensation and air drying.

[0058] The basic principle of dehumidification is based on the phase change heat exchange mechanism in the refrigeration cycle. When the dehumidifier 10 starts, the compressor 123 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas and delivers it to the condenser. In the condenser, the high-temperature refrigerant releases heat to the surrounding environment and condenses into a high-pressure liquid. Subsequently, the liquid refrigerant is depressurized through a throttling device (such as a capillary tube or electronic expansion valve), transforming into a low-temperature, low-pressure gas-liquid mixture and entering the evaporator. At this time, the fan assembly 122 drives the humid indoor air to flow across the fins and pipe surfaces of the evaporator. Since the surface temperature of the evaporator is much lower than the dew point temperature of the air, water vapor in the air condenses upon encountering the cold air, precipitating liquid water droplets. These condensates drip into the water collection container 124 located below the dehumidification module 121 under the influence of gravity, thereby effectively removing moisture from the air.

[0059] The air temperature after dehumidification by the evaporator is low, and direct discharge may cause discomfort or localized condensation. Therefore, in some embodiments, the low-temperature, dry air continues to flow through the condenser. The condenser not only dissipates heat but also acts as a reheater, reheating the low-temperature air into a warm, dry airflow. Finally, this dehumidified and moderately reheated air is pushed by the fan assembly 122 to the air outlet 112 and discharged from the top of the casing 110, returning to the indoor environment. This "cooling and dehumidifying first, then heating and discharging" process ensures both efficient dehumidification and improved airflow comfort.

[0060] Furthermore, both the dehumidification module 121 and the fan assembly 122 are located above the compressor 123. As the heaviest component in the dehumidifier 10, placing the compressor 123 at the bottom lowers the overall center of gravity, improving the stability of the dehumidifier 10 during operation and preventing displacement or tipping due to vibration. Simultaneously, the dehumidifier body 120 also includes a water collection container 124, located below the dehumidification module 121. Utilizing gravity, the condensate produced by the dehumidification module 121 during cooling naturally drips into the water collection container 124 below. This non-powered water collection method is simple and reliable, avoiding the risk of water leakage.

[0061] To facilitate daily maintenance, the dehumidifier 10 also includes a first filter cover 141 and a second filter cover 142. The first filter cover 141 is detachably mounted on the first air inlet 113, and the second filter cover 142 is detachably mounted on the second air inlet 114. The filter covers can be fixed by means of snap-fit ​​connection, magnetic connection, or threaded connection. When the user needs to clean or replace the filter, they only need to remove the filter cover to take out the filter assembly, which is simple and quick to operate and greatly improves the user experience.

[0062] In some embodiments, the air outlet 112 is located at the top of the outer casing 110, which is one of the key design features in the overall airflow layout of the dehumidifier 10 of this application. This location arrangement fully considers the natural flow characteristics of hot air and the space utilization efficiency of the overall structure. Since the dry air generated during the dehumidification process usually has a high temperature and low density, it will naturally rise without external intervention. Placing the air outlet 112 at the top of the outer casing 110 can follow the upward trend of hot air, effectively reducing the airflow resistance in the internal channel, thereby improving the overall airflow efficiency and dehumidification performance of the unit.

[0063] Furthermore, the top-exhaust structure helps achieve more uniform indoor air circulation. As dry, hot air is exhausted from the top, it quickly mixes with the humid air in the upper part of the room, forming a top-down air circulation path under the influence of gravity and convection. This circulation method not only accelerates the humidity equalization process throughout the room but also prevents mold or odor problems caused by excessive humidity in certain areas, making it particularly suitable for use in scenarios with high air quality requirements, such as bedrooms, walk-in closets, or basements.

[0064] From the perspective of product appearance and human-computer interaction, placing the air outlet 112 at the top also brings significant advantages. On the one hand, this design avoids the direct hot air impact that side air outlets might cause to users, improving user comfort; on the other hand, the top air outlet 112 facilitates integration with the air guide shroud assembly 300. In drying mode, the air guide shroud 310 can rotate or cover the top air outlet 112, precisely guiding hot air downwards towards the item support rack 200 below, achieving efficient directional drying. In regular dehumidification mode, the air guide shroud 310 can be fully opened or closed, allowing hot air to be smoothly discharged into the indoor environment without affecting the normal dehumidification function.

[0065] Meanwhile, the location of the top air outlet 112 also facilitates the rational layout of internal components. Heavier components, such as the compressor 123 and the water collection container 124, which rely on gravity for operation, can be concentrated at the bottom of the outer casing 110, while the fan assembly 122 and the dehumidification module 121 are located in the upper middle part, close to the air outlet 112, shortening the transmission path of high-temperature and high-humidity airflow and reducing energy loss. This layered structural design not only optimizes the overall center of gravity and improves operational stability, but also facilitates the collection and discharge of condensate, further enhancing the product's reliability and ease of maintenance.

[0066] To improve the portability of the dehumidifier 10, the dehumidifier 10 also includes a moving component 500, which is located at the bottom of the housing 110. The moving component 500 can be a caster wheel, roller, or other similar device, allowing users to easily move the dehumidifier 10 between different rooms to meet the needs of whole-house dehumidification.

[0067] The item support rack 200 is rotatably mounted on the outer casing 110. When the user needs to dry items, the item support rack 200 can be rotated to the unfolded state for hanging clothes or placing shoes; when drying is not required, the item support rack 200 can be rotated and folded into the side wall or top of the outer casing 110, reducing the space occupied by the dehumidifier 10 and making its appearance neater and more compact. This rotating and retractable structure can be achieved through a damping pivot or a limiting hinge, ensuring both load-bearing capacity when unfolded and convenient storage.

[0068] Please see Figure 8 and Figure 9 In some embodiments, the dehumidifier body 100 includes a housing 110, a first filter assembly 131, a second filter assembly 132, a dehumidification module 121, and a fan assembly 122. The housing 110 has a first air inlet channel 117, a second air inlet channel 118, and an air outlet 112. The first filter assembly 131 is disposed within the first air inlet channel 117, and the second filter assembly 132 is disposed within the second air inlet channel 118. The dehumidification module 121 is disposed within the housing 110. The fan assembly 122 is disposed within the housing 110 and is used to drive air to enter through the first air inlet channel 117 and the second air inlet channel 118, and to exit through the air outlet 112.

[0069] The first air intake channel 117 guides airflow sequentially through the first filter assembly 131 and the dehumidification module 121. This means that air drawn in through the first air intake channel 117 undergoes preliminary filtration through the first filter assembly 131 to remove large particles such as dust and hair, before entering the dehumidification module 121. In the dehumidification module 121, the air exchanges heat with the refrigerant heat exchanger, causing moisture in the air to condense and become dry, cold air or reheated, dry, hot air. This channel primarily performs the dual functions of dehumidification and purification, making it suitable for scenarios with high humidity where rapid reduction in humidity is required.

[0070] Parallel to this, the second air inlet channel 118 guides airflow through the second filter assembly 132, and the airflow within the second air inlet channel 118 bypasses the dehumidification module 121. Here, "bypass" means that the second air inlet channel 118 physically avoids the area where the dehumidification module 121 is located. Specifically, the interior of the outer casing 110 is divided into independent airflow paths by partitions or duct walls, so that the air entering from the second air inlet channel 118 is only filtered by the second filter assembly 132, and then directly drawn in and discharged by the fan assembly 122, without passing through the evaporator and condenser of the dehumidification module 121. This channel primarily performs the function of "purification only." Because the airflow does not need to pass through the dehumidification module 121, the wind resistance is significantly reduced, the fan can output a larger air volume at the same power, and the outlet air temperature will not be too low or too high due to passing through the cooling system. This is suitable for scenarios with suitable ambient humidity but poor air quality (such as smoggy days or strong odors after renovation).

[0071] It should be understood that this dual-airflow design enables flexible combinations of functions. In actual operation, the dehumidifier 10 can intelligently select its operating mode based on environmental parameters detected by sensors (such as temperature, humidity, and PM2.5 concentration) or user commands. For example, when the ambient humidity is high but the air quality is acceptable, only the first air intake channel 117 can be opened, utilizing the dehumidification module 121 for full-force dehumidification; when the environment is dry but the air is turbid, only the second air intake channel 118 can be opened, utilizing a large flow rate to purify the air, avoiding the energy waste caused by the traditional dehumidifier 10 forcibly running the compressor 123 in purification mode; when the environment is both humid and turbid, both channels can be opened simultaneously, increasing the circulating air volume while dehumidifying, accelerating indoor air circulation, and improving purification efficiency. This structural "decoupling" design greatly enriches the usage scenarios of the dehumidifier 10 and improves energy utilization.

[0072] Furthermore, this embodiment does not strictly limit the specific implementation of the "bypass". As one implementation, the bypass can be a duct completely independent of the dehumidification module 121, with the duct wall physically isolating the airflow from the dehumidification module 121. As another implementation, the bypass can also be an open air duct formed within the internal space of the outer casing 110, guiding the airflow through a guide structure to bypass the dehumidification module 121 and directly enter the air intake of the fan assembly 122. As long as the airflow does not pass through the heat exchanger of the dehumidification module 121, it should fall within the scope of protection of this application.

[0073] This application, by setting a second air inlet channel 118, allows part of the airflow to bypass the dehumidification module 121 and be discharged directly, significantly reducing the total air volume that needs to pass through the dehumidification module 121, thereby effectively reducing the workload of the fan assembly 122. This not only helps to extend the fan's lifespan but also achieves a higher overall air volume output at the same power, improving equipment operating efficiency.

[0074] In addition, by diverting part of the airflow to the second air inlet channel 118 that does not pass through the dehumidification module 121, this application reduces the proportion of flow on the high-resistance path, thereby effectively suppressing the noise caused by excessive airflow resistance, making the whole machine operate more quietly and significantly improving the user's comfort.

[0075] When rapid dehumidification is needed, users primarily rely on the first air intake channel 117. When humidity is low or only air filtration / recirculation is required, the airflow ratio of the second air intake channel 118 can be increased by adjusting the damper or control logic. In this way, the device can efficiently complete the dehumidification task and can also be used as a general air purification or ventilation device in non-high humidity environments, enhancing the product's versatility and flexibility in applicable scenarios.

[0076] In some embodiments, the first air inlet channel 117 and the second air inlet channel 118 are located on opposite sides of the fan assembly 122. This symmetrical layout is not an arbitrary arrangement, but rather based on in-depth considerations of fluid mechanics and mechanical dynamics. When the fan assembly 122 rotates at high speed to drive the airflow, if only unilateral or asymmetrical air inlet is used, the axial or radial forces generated by the airflow on the fan impeller are often unbalanced. This unbalanced force will cause the bearings of the fan assembly 122 to bear additional off-center loads, thereby accelerating bearing wear, shortening service life, and generating greater mechanical vibration and noise.

[0077] In this embodiment, the first air inlet channel 117 and the second air inlet channel 118 are located on opposite sides of the fan assembly 122 (e.g., left and right sides, or front and rear sides), forming a symmetrical air inlet structure. When the fan assembly 122 is working, airflow is simultaneously drawn into the air inlet chamber of the fan assembly 122 from both opposite sides. According to the principle of mechanical composition, the lateral thrust generated by the airflow on both sides on the fan impeller is equal in magnitude and opposite in direction, thus canceling each other out inside the fan assembly 122. This force balance greatly improves the operating environment of the fan assembly 122, making the impeller rotate more smoothly and reducing vibration and sway caused by uneven force. Therefore, this symmetrical layout not only significantly reduces the noise of the dehumidifier 10 during operation and improves user comfort, but also effectively extends the service life of the fan assembly 122 and the entire dehumidifier 10.

[0078] Furthermore, the first air inlet channel 117 has a first air inlet 113, and the second air inlet channel 118 has a second air inlet 114. Both the first air inlet 113 and the second air inlet 114 are located on the sides of the outer casing 110 and on opposite sides of the outer casing 110. This design of placing the air inlets on opposite sides of the outer casing 110 echoes the aforementioned symmetrical layout inside the air duct, forming a symmetrical flow path from the outside of the outer casing 110 to the internal fan assembly 122. Specifically, the arrangement of the opposite sides of the outer casing 110 ensures that both sides of the dehumidifier 10 have unobstructed air intake space when placed indoors, avoiding the risk of one side of the air inlet being blocked due to placement against a wall or in a corner. Even if one side of the dehumidifier 10's air inlet is close to the wall, the other side's air inlet can still remain unobstructed, thus ensuring the stability of the overall air intake volume. In addition, this dual-side air intake design is conducive to the circulation of indoor air, and can more quickly draw humid air from different areas of the room into the dehumidifier 10 for processing, thus improving dehumidification efficiency.

[0079] It should be understood that although this embodiment focuses on the preferred embodiment where the first air inlet channel 117 and the second air inlet channel 118 are located on opposite sides of the fan assembly 122, in other embodiments, depending on the limitations of the internal space of the housing 110 or the layout requirements of specific components, the two air inlet channels may also be located on adjacent sides of the fan assembly 122, or arranged at a certain angle. Furthermore, the positions of the first air inlet 113 and the second air inlet 114 on the housing 110 are not limited to strict geometric symmetry; as long as they can achieve dual-sided air intake and roughly balance the airflow, they should fall within the scope of protection of this application.

[0080] This embodiment, in conjunction with a specific application scenario, provides a detailed description of the usage method and working principle of the dehumidifier 10 provided in this application. It should be understood that the following scenarios are merely exemplary applications of the technical solution of this application and do not constitute a limitation on the scope of protection of this application.

[0081] Scenario 1: The user needs to dry the damp shoes.

[0082] In this scenario, the user first unfolds the air guide shroud assembly 300 from its retracted state. Specifically, the user applies force to rotate the air guide shroud 310, causing it to overcome the resistance of the elastic locking mechanism 400 and rotate from the first position (retracted position) to the second position (working position). During this process, the rotating shaft structure 311 on the air guide shroud 310 rotates within the rotating groove of the dehumidifier body 100, and the stop member 102 slides within the stop groove 314 until the stop member 102 abuts against the end wall of the stop groove 314, restricting further rotation of the air guide shroud 310. At this point, the locking ball, under the action of the elastic element, engages with the second groove 313, achieving positioning. When the air guide shroud 310 is in the second position, its internal space is connected to the air outlet 112 area of ​​the dehumidifier body 100, and part of the structure of the dehumidifier body 100 is located within the air guide shroud 310, forming a closed air guide chamber.

[0083] Subsequently, the user closes the air guide baffle 320, sealing the first air guide vent 115 on the air guide cover 310. At this time, the dehumidifier 10 enters its second operating state. The fan assembly 122 inside the dehumidifier body 100 starts, driving airflow. Since the first air guide vent 115 is sealed, the airflow cannot exit from the front of the air guide cover 310 and must find another outlet. At this time, the second air guide vent 116 formed between the air guide cover 310 and the dehumidifier body 100 becomes the only air outlet channel. Under the action of pressure difference, the airflow is forced to flow towards the second air guide vent 116.

[0084] The user places the shoes to be dried on the shelf 200. Since the shelf 200 is located below the air guide 310, and the second air vent 116 faces the shelf 200, the hot air exhausted from the second air vent 116 blows directly onto the surface of the shoes. The hot air, with its high temperature and low relative humidity, can quickly remove moisture from the shoe surface and penetrate into the shoe's interior, achieving rapid drying. This concentrated airflow method significantly improves heat energy utilization and shortens drying time compared to the naturally diffused hot air of a traditional dehumidifier 10. Especially for hard-to-dry areas such as the toe and heel, the directional hot air can penetrate deeply, avoiding dead spots. Simultaneously, due to the converging effect of the air guide 310, the hot air forms a micro-circulation around the shoes, further improving drying efficiency.

[0085] Scenario 2: Users only need to dehumidify the indoor environment.

[0086] In this scenario, the user rotates the air guide cover 310 to the first position, so that it fits against or covers the air outlet 112 area of ​​the dehumidifier body 100. At this time, the locking ball engages with the first groove 312, and the air guide cover 310 is securely positioned. The user opens the air guide baffle 320, so that the first air guide vent 115 is open. The dehumidifier 10 enters the first working state.

[0087] The dry, hot air generated by the dehumidifier body 100 is discharged through the air outlet 112 and then blown directly into the external environment through the open first air guide 115. Since the first air guide 115 typically has a large opening area and a straight airflow path, airflow resistance is minimal. This direct-venting airflow design allows the dehumidifier 10 to operate at maximum power, quickly reducing indoor air humidity. At this time, the item support rack 200 can be rotated and stored on the side wall of the outer casing 110, without occupying extra space and maintaining the clean appearance of the dehumidifier 10.

[0088] Scenario 3: Users need to purify indoor air, and the ambient humidity is suitable, so dehumidification is not required.

[0089] In this scenario, the dehumidifier 10 utilizes its unique dual-airflow structure to achieve the "purification-only" function. Specifically, the first air intake channel 117 and the second air intake channel 118 inside the dehumidifier body 100 simultaneously draw in air.

[0090] The fan assembly 122 drives the airflow. Air entering through the first air inlet duct 117 is filtered by the first filter assembly 131 and processed by the dehumidification module 121. Due to suitable ambient humidity, refrigeration components such as the compressor 123 may not need to be started, and the dehumidification module 121 serves only as part of the airflow channel or performs only minor heat exchange regulation. Air entering through the second air inlet duct 118 is filtered by the second filter assembly 132 and then bypasses the dehumidification module 121 before flowing to the fan assembly 122.

[0091] The two airflows converge at the fan assembly 122 and finally exhaust clean air from the air outlet 112. Because the second air intake duct 118 bypasses the dehumidification module 121, wind resistance is significantly reduced, allowing the fan assembly 122 to draw in more air at the same rotation speed, thus greatly increasing the circulating air volume and accelerating indoor air purification. Simultaneously, since there is no need to start the compressor 123 for cooling and dehumidification, the overall energy consumption is significantly reduced, and noise is also decreased. This dual-duct collaborative working mode allows the dehumidifier 10 to transform into a high-performance air purifier in seasons when dehumidification is not required (such as spring and autumn), offering multiple uses and enhancing the product's usability and user experience.
