Description

Technical Field

[0001] The invention relates to a gas drying device, in particular to a dehumidifier. Background Art

[0002] There are many ways to dehumidify with a dehumidifier, such as physical dehumidification and chemical dehumidification. For physical dehumidification using adsorbents such as dehumidifying beads, people put the packaging box or packaging bag containing the adsorbents such as dehumidifying beads into the space that needs to be dehumidified. When the adsorbents such as dehumidifying beads absorb too much water vapor and become ineffective, some people will directly discard the entire thing, while others will use drying, sun drying, etc. to reprocess the adsorbents such as dehumidifying beads and recycle them. However, the operation is relatively cumbersome, especially when processing multiple packaging boxes or packaging bags, it takes a lot of time. Therefore, there is an urgent need for a dehumidifier that can be easily and repeatedly used. Summary of the invention

[0003] The object of the present invention is to provide a dehumidifier to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A dehumidifier comprises: a base, an air outlet is arranged on the top side, an air inlet is arranged on the bottom side of the base, a fan is arranged in the base, and the fan can form an airflow in the base that flows from the air inlet to the air outlet; a dehumidifier box, a plurality of upper ventilation holes are arranged on the top side, and a plurality of lower ventilation holes are arranged on the bottom side, a ventilation frame is connected to the dehumidifier box, the ventilation frame is surrounded by a ventilation channel arranged in the up and down directions, a plurality of side ventilation holes are arranged on the side walls of the ventilation frame, a switch assembly is arranged on the top side of the ventilation frame, and the switch assembly can open or close the plurality of upper ventilation holes corresponding to the ventilation channel, the dehumidifier box is detachably connected with a plurality of boxes in the up and down directions, the dehumidifier box located at the bottom is detachably connected to the top side of the base, the switch assembly in the dehumidifier box located at the top is in a closed state, and the switch assembly in the dehumidifier box located between the top dehumidifier box and the base is in an open state.

[0006] The technical solution has at least the following beneficial effects: a space for placing adsorbents such as dehumidification beads is formed between the inner side of the dehumidification box and the ventilation frame. When dehumidification is needed, the dehumidification box can be removed from the base, and multiple dehumidification boxes can be separated from each other so as to be placed in different positions for independent use. When a single dehumidification box needs to be dehumidified, the dehumidification box is connected to the top side of the base. At this time, the switch component located in the dehumidification box is in a closed state. The fan is turned on, and an airflow is formed in the base that blows out from the air inlet to the air outlet. The airflow enters the dehumidification box from the multiple lower vents on the bottom side of the dehumidification box. Since the switch component closes the multiple upper vents facing the ventilation channel, the airflow will not flow directly upward from the ventilation channel, but will be diverted to the surroundings and blown from the multiple side vents on the side wall of the ventilation frame to the adsorbents such as dehumidification beads, bringing out the water vapor from the multiple upper vents on the top side of the base, thereby drying the dehumidification beads. When there are multiple dehumidification boxes, the multiple dehumidification boxes are stacked up and down. The switch component in the dehumidifier box at the top is in a closed state, while the switch component in the dehumidifier box located between the top dehumidifier box and the base is in an open state. The airflow blown out from the base enters the bottom dehumidifier box, and part of the airflow is diverted to the surroundings from the internal ventilation channel, taking away the water vapor in the dehumidifier box and then entering the dehumidifier box above it through the upper ventilation holes, while part of the airflow goes directly upward from the ventilation channel through the upper ventilation holes and then enters the dehumidifier box above it, thereby realizing simultaneous processing of multiple dehumidifier boxes, and the switch component in the dehumidifier box located at the top is in a closed state, so that the airflow flowing into the top ventilation channel will not be discharged directly upward, but will be diverted to the surroundings to take away the water vapor in the top dehumidifier box, thereby improving the efficiency of simultaneous processing of multiple dehumidifier boxes. Therefore, the present invention has multiple dehumidifier boxes that can be detached and used separately, which is flexible to use. When recycling is required, multiple dehumidifier boxes can be processed simultaneously on the base, greatly improving the overall convenience and user experience.

[0007] As a further improvement of the above technical solution, the switch assembly includes a cover plate and a guide sleeve, the guide sleeve is connected to the inner top side of the dehumidification box, the bottom end of the guide sleeve is connected to an anti-drop cap, the cover plate can move up and down along the guide sleeve, a plurality of connecting holes are arranged on the cover plate, the plurality of connecting holes and the plurality of upper ventilation holes are staggered with each other, a spring is arranged on the outer side of the guide sleeve, the top end of the spring abuts against the bottom side of the cover plate, the bottom end of the spring abuts against the anti-drop cap, the spring has a tendency to press the cover plate upward against the inner top side of the dehumidification box, a pressure block that passes through the dehumidification box upward is connected to the top side of the cover plate, and in two adjacent dehumidification boxes above and below, the dehumidification box located above presses the pressure block located below downward into the dehumidification box. When the dehumidifier box is in a single use state, the spring presses the cover plate against the top side of the dehumidifier box, so that the pressure block on the top side of the cover plate passes upward out of the dehumidifier box. Since the multiple connecting holes on the cover plate and the multiple upper ventilation holes are staggered with each other, the cover plate can block and close the multiple upper ventilation holes on the top side of the dehumidifier box, thereby closing the ventilation channel. When multiple dehumidifiers are stacked up and down, the bottom side of the dehumidifier box located at the top will press the pressure block in the dehumidifier box located below downward, and drive the cover plate to move downward along the guide sleeve through the pressure block. At this time, the spring between the cover plate and the anti-drop cap is elastically compressed. Since the cover plate leaves the top side of the dehumidifier box, the upper ventilation holes on the top side of the dehumidifier box can be opened. The airflow blown upward from the ventilation channel can continue to be discharged upward from the multiple upper ventilation holes on the top side of the dehumidifier box after passing through the multiple connecting holes on the cover plate, and enter the dehumidifier box located above it. The stacking of the upper and lower dehumidifier boxes is cleverly utilized to realize automatic opening or closing of the switch assembly.

[0008] As a further improvement of the above technical solution, the inner top side of the dehumidification box is connected to a limiting frame, and the cover plate is located in the limiting frame. The limiting frame can surround and protect the cover plate and limit the horizontal deviation of the cover plate, thereby improving the stability of the cover plate's up and down movement.

[0009] As a further improvement of the above technical solution, the top of the ventilation frame is sleeved on the outside of the limit frame, and the inner side of the ventilation frame is connected with an upper limit rib, and the upper limit rib abuts against the bottom side of the limit frame. When the ventilation frame is installed in the dehumidifier box, the top of the ventilation frame is sleeved on the outside of the limit frame, and the upper limit rib on the inner side of the ventilation frame abuts against the bottom side of the limit rib, which can limit the installation depth of the ventilation frame, thereby improving the convenience of installing the ventilation frame and making the ventilation frame more stable when installed in the dehumidifier box.

[0010] As a further improvement of the above technical solution, the bottom side of the dehumidifier box is detachably connected to a bottom cover, and the top side of the bottom cover is connected to a lower limiting rib, which abuts against the bottom inner side of the ventilation frame. During maintenance, the moisture absorbing beads and other adsorbents inside the dehumidifier box can also be replaced. At this time, the bottom cover on the bottom side of the dehumidifier box can be opened and connected to the dehumidifier box. Since the lower limiting rib on the top side of the bottom cover abuts against the bottom inner side of the ventilation frame, the bottom of the ventilation frame can be limited, so that the whole can be quickly disassembled and assembled, and the whole connection is stable.

[0011] As a further improvement of the above technical solution, a lower enclosure frame protruding downward is formed on the bottom side of the bottom cover, and an upper enclosure frame protruding upward is formed on the top side of the dehumidification box. In the two adjacent dehumidification boxes above and below, the lower enclosure frame located at the bottom is inserted into the upper enclosure frame located above. The upper enclosure frame on the top side of the dehumidification box is surrounded to form a connection limit area. When the upper and lower dehumidification boxes are connected to each other, the lower enclosure frame of the upper dehumidification box is aligned with the area and inserted into the interior, so that the upper and lower dehumidification boxes can be quickly connected, and the connection stability is high and relative horizontal displacement is not easy to occur.

[0012] As a further improvement of the above technical solution, the upper ventilation holes are arranged in a plurality in the horizontal direction and in the vertical direction, and the lower ventilation holes are arranged in a plurality in the horizontal direction and in the vertical direction. The plurality of upper ventilation holes are arranged in a horizontal direction and in the vertical direction, and the structural strength of the top side of the dehumidifier box is better taken into account while ensuring the air outlet of the top side of the dehumidifier box. Similarly, the plurality of lower ventilation holes are arranged in a horizontal direction and in the vertical direction, and the structural strength of the bottom side of the dehumidifier box is better taken into account while ensuring the air inlet of the bottom side of the dehumidifier box.

[0013] As a further improvement of the above technical solution, the top side of the base is recessed downward to form a transition groove, and the plurality of upper ventilation holes are respectively formed at the bottom of the transition groove. The transition groove can form a space for air flow between the air inlet position of the dehumidifier box located at the bottom and the base. When the airflow is blown upward from the base, it passes through the transition groove and is dispersed to the plurality of lower ventilation holes on the bottom side of the dehumidifier box, and then enters the dehumidifier box, thereby improving the uniformity of air entering the dehumidifier box.

[0014] As a further improvement of the above technical solution, an air guide sleeve is connected to the top side of the base, and the air guide sleeve is directly opposite to the air outlet of the fan, and a heater is connected inside the air guide sleeve. When the fan is discharging air, it passes through the air guide sleeve, and the airflow is heated by the heater before being blown upward. The air guide sleeve can make the heat generated by the heater more concentrated, thereby improving the heating efficiency of the airflow. When the airflow is blown into the dehumidifier, the hot air is used to dry the adsorbents such as the dehumidification beads in the dehumidification box, further improving the dehumidification efficiency and quality.

[0015] As a further improvement of the above technical solution, the dehumidifier box is connected with a hanging ear. When the dehumidifier is used alone, it can be hung on the structural member of the external device through the hanging ear, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Reference Figures 1 to 4 A dehumidifier comprises a base 100 and a dehumidification box 200, wherein an air outlet 110 is arranged on the top side of the base 100, an air inlet is arranged on the bottom side of the base 100, a fan 140 is arranged inside the base 100, and the fan 140 can form an airflow from the air inlet to the air outlet 110 in the base 100; a plurality of upper ventilation holes 210 are arranged on the top side of the dehumidification box 200, a plurality of lower ventilation holes 220 are arranged on the bottom side of the dehumidification box 200, a ventilation frame 230 is connected to the dehumidification box 200, and the ventilation frame 230 is surrounded by ventilation holes arranged in the up and down directions. Channel, the side wall of the ventilation frame 230 is provided with a plurality of side ventilation holes 231, the top side of the ventilation frame 230 is provided with a switch assembly, the switch assembly can open or close the plurality of upper ventilation holes 210 corresponding to the ventilation channel, the dehumidification box 200 is detachably connected with a plurality of them along the up and down directions, the dehumidification box 200 located at the bottom is detachably connected to the top side of the base 100, the switch assembly in the dehumidification box 200 located at the top is in a closed state, and the switch assembly in the dehumidification box 200 located between the top dehumidification box 200 and the base 100 is in an open state.

[0028] As can be seen from the above, a space for placing dehumidification beads and other adsorbents is formed between the inner side of the dehumidification box 200 and the ventilation frame 230. When dehumidification is needed, the dehumidification box 200 can be removed from the base 100, and multiple dehumidification boxes 200 can be separated from each other so as to be placed in different positions for independent use. When a single dehumidification box 200 needs to be dehumidified, the dehumidification box 200 is connected to the top side of the base 100. At this time, the switch component in the dehumidification box 200 is in the closed state, and the fan 140 is turned on. A fan is formed in the base 100 to blow out air from the air inlet to the air outlet 110. The airflow enters the dehumidifier box 200 from the multiple lower ventilation holes 220 on the bottom side of the dehumidifier box 200. Since the switch assembly closes the multiple upper ventilation holes 210 facing the ventilation channel, the airflow will not flow directly upward from the ventilation channel, but will be diverted to the surroundings and blown to the dehumidifier beads and other adsorbents from the multiple side ventilation holes 231 on the side wall of the ventilation frame 230, bringing out the water vapor from the multiple upper ventilation holes 210 on the top side of the base 100, thereby drying the dehumidifier beads. When there are multiple dehumidifier boxes 200, the multiple dehumidifier boxes 200 are stacked up and down. The switch assembly in the upper dehumidifier box 200 is in a closed state, while the switch assembly in the dehumidifier box 200 located between the uppermost dehumidifier box 200 and the base 100 is in an open state, and the airflow blown out from the base 100 enters the lowermost dehumidifier box 200, and part of the airflow is diverted to the surroundings from the internal ventilation channel, taking away the water vapor in the dehumidifier box 200 and then passing through the upper ventilation hole 210 to enter the dehumidifier box 200 above it, while part of the airflow goes directly upward from the ventilation channel through the upper ventilation hole 210 and then enters the dehumidifier box 200 above it, thus achieving dehumidification of multiple dehumidifier boxes. The dehumidification boxes 200 are processed simultaneously, and the switch component in the dehumidification box 200 located at the top is in a closed state, so that the airflow flowing into the top ventilation channel will not be discharged directly upward, but will be diverted to the surroundings to take away the water vapor located in the top dehumidification box 200, thereby improving the efficiency of processing multiple dehumidification boxes 200 at the same time. Therefore, the present invention has multiple dehumidification boxes 200 that can be detached and used separately, which is flexible to use. When recycling is required, multiple dehumidification boxes 200 can be processed simultaneously on the base 100, which greatly improves the overall convenience and user experience.

[0029] In order to prevent the airflow in the ventilation channel from being directly discharged upward from the top dehumidification box 200, it is necessary to close the upper ventilation hole 210 located at the top dehumidification box 200 facing the ventilation channel. Therefore, a switch assembly is arranged on the top side of the dehumidification box 200, and the upper ventilation hole 210 is switched on and off by the switch assembly. There are various structural forms of the switch assembly. For example, the switch assembly can use an active driving source. In the present embodiment, the switch assembly includes a cover plate 241 and a guide sleeve 242. The guide sleeve 242 is connected to the inner top side of the dehumidification box 200. The bottom end of the guide sleeve 242 is connected with an anti-drop cap 243. The anti-drop cap 243 can be a connecting piece such as a screw, which can be easily installed and removed from the bottom end of the guide sleeve 242. For example, when a screw is used for the anti-drop cap 243, the head of the screw is used to prevent the bottom end of the spring 245 from dropping out. The cover plate 241 can move up and down along the guide sleeve 242. The cover plate 241 is provided with a plurality of connecting holes 244, and the plurality of connecting holes 244 are staggered with the plurality of upper ventilation holes 210, and a spring 245 is sleeved on the outer side of the guide sleeve 242, and the top end of the spring 245 abuts against the bottom side of the cover plate 241, and the bottom end of the spring 245 abuts against the anti-drop cap 243, and the spring 245 has a tendency to press the cover plate 241 upward against the top side of the dehumidification box 200, and the cover plate 24 The top side is connected with a pressing block 246 which passes through the dehumidification box 200 upwards. In the two adjacent dehumidification boxes 200 above and below, the dehumidification box 200 located at the upper side presses the pressing block 246 located at the lower side downwards into the dehumidification box 200. There can be multiple pressing blocks 246. For example, there are two pressing blocks 246. Naturally, an opening is reserved at the position of the top side of the dehumidification box 200 facing the two pressing blocks 246, so that the two pressing blocks 246 can pass through.

[0030] When the above-mentioned switch assembly is used, when the dehumidifier box 200 is used alone, the spring 245 presses the cover plate 241 against the top side of the dehumidifier box 200, so that the pressing block 246 on the top side of the cover plate 241 passes upward out of the dehumidifier box 200. Since the multiple connecting holes 244 on the cover plate 241 and the multiple upper ventilation holes 210 are staggered with each other, the cover plate 241 can block and close the multiple upper ventilation holes 210 on the top side of the dehumidifier box 200, thereby closing the ventilation channel. When multiple dehumidifiers are stacked up and down, the bottom side of the dehumidifier box 200 located above will press the pressing block 246 in the dehumidifier box 200 located below downward. The cover plate 241 is driven by the pressing block 246 to move downward along the guide sleeve 242. At this time, the spring 245 located between the cover plate 241 and the anti-drop cap 243 is elastically compressed. Since the cover plate 241 leaves the top side of the dehumidification box 200, the upper ventilation hole 210 on the top side of the dehumidification box 200 can be opened, and the airflow blown upward from the ventilation channel can continue to be discharged upward from the multiple connecting holes 244 on the cover plate 241 through the multiple upper ventilation holes 210 on the top side of the dehumidification box 200, and enter the dehumidification box 200 located above it. In this way, the stacking of the upper and lower dehumidification boxes 200 is cleverly utilized to realize the automatic opening or closing of the switch assembly.

[0031] When the cover plate 241 moves up and down along the guide sleeve 242, the cover plate 241 can be slid inside the ventilation frame 230, or the guide sleeve 242 passes through the limit position of the cover plate 241, so that the cover plate 241 can move up and down. Figure 5 As shown, the inner top side of the dehumidification box 200 is connected to a limiting frame 250, and the cover plate 241 is located in the limiting frame 250. In practical applications, the limiting frame 250 has a variety of shapes, for example, the limiting frame 250 can be rectangular or circular, and in order to better limit the ventilation frame 230, the shape of the limiting frame 250 and the shape of the cover plate 241 are mutually adapted, for example, when the shape of the cover plate 241 is rectangular, the shape of the limiting frame 250 can also be rectangular. The limiting frame 250 can surround and protect the cover plate 241, and limit the horizontal deviation of the cover plate 241, thereby improving the stability of the up and down movement of the cover plate 241.

[0032] The ventilation frame 230 is located in the dehumidification box 200, and it can be installed in different positions. For example, the ventilation frame 230 is installed in the middle of the dehumidification box 200. At this time, space for placing adsorbents such as dehumidification beads is formed between the four sides of the ventilation frame 230 and the inner side of the dehumidification box 200. In order to facilitate the installation and fixation of the ventilation frame 230 in the dehumidification box 200, in this embodiment, the top of the ventilation frame 230 is sleeved on the outer side of the limit frame 250, and the inner side of the ventilation frame 230 is connected to an upper limit rib 232, and the upper limit rib 232 is against the bottom side of the limit frame 250. In actual applications, the shape of the ventilation frame 230 can also be rectangular, and the upper limit rib 232 can extend around the center of the ventilation frame 230 on the inner side of the ventilation frame 230, thereby providing support for the bottom side of the limit frame 250 at various positions. When the ventilation frame 230 is installed in the dehumidification box 200, the top of the ventilation frame 230 is mounted on the outside of the limit frame 250, and the upper limit rib 232 on the inner side of the ventilation frame 230 is against the bottom side of the limit rib, so that the installation depth of the ventilation frame 230 can be limited. This can improve the convenience of installing the ventilation frame 230 and make the ventilation frame 230 more firmly installed in the dehumidification box 200.

[0033] In order to facilitate the internal maintenance of the dehumidification box 200, in the present embodiment, the bottom side of the dehumidification box 200 is detachably connected to a bottom cover 260. For example, the bottom cover 260 can be connected to the bottom side of the dehumidification box 200 by a snap, or can be directly connected to the bottom side of the dehumidification box 200 by an interference fit. The top side of the bottom cover 260 is connected to a lower limit rib 262, and the lower limit rib 262 abuts against the inner side of the bottom of the ventilation frame 230. In actual application, the lower limit rib 262 extends around the center of the dehumidification box 200 to form a rectangle. At this time, the rectangular lower limit rib 262 is adapted to the inner shape of the bottom of the ventilation frame 230, thereby limiting the bottom of the ventilation frame 230. During maintenance, the adsorbent materials such as the desiccant beads inside the dehumidifier box 200 can also be replaced. At this time, the bottom cover 260 on the bottom side of the dehumidifier box 200 can be opened, and the bottom cover 260 can be connected to the dehumidifier box 200. Since the lower limit rib 262 on the top side of the bottom cover 260 abuts against the inner side of the bottom of the ventilation frame 230, the bottom limit of the ventilation frame 230 can be achieved, so that the whole can be quickly disassembled and assembled, and the overall connection is stable.

[0034] In order to facilitate the stacking and limiting of the upper and lower dehumidification boxes 200, in this embodiment, a structure for facilitating assembly can be provided between the two dehumidification boxes 200. Specifically, a lower enclosure frame 261 protruding downward is formed on the bottom side of the bottom cover 260, and an upper enclosure frame 270 protruding upward is formed on the top side of the dehumidification box 200. In the two adjacent dehumidification boxes 200, the lower enclosure frame 261 located at the bottom is inserted into the upper enclosure frame 270 located at the top. The upper enclosure frame 270 on the top side of the dehumidification box 200 is surrounded to form a connection and limiting area. When the upper and lower dehumidification boxes 200 are connected to each other, the lower enclosure frame 261 of the upper dehumidification box 200 is aligned with the area and inserted into the interior, so that the upper and lower dehumidification boxes 200 can be quickly connected, and the connection stability is high and relative horizontal displacement is not easy to occur. In actual applications, the shape of the upper frame 270 and the shape of the lower frame 261 are respectively rectangular. In order to facilitate the connection and alignment of the upper frame 270 and the lower frame 261, the side of the lower frame 261 away from the center can be tilted, and the side wall is tilted from bottom to top away from the center of the lower frame 261. Similarly, a side wall of the upper frame 270 close to its center is also tilted, and its shape is compatible with the shape of the inclined side wall of the lower frame 261.

[0035] In order to improve the ventilation effect inside and outside the dehumidification box 200, the shape of the upper ventilation hole 210 and the shape of the lower ventilation hole 220 can be set to a strip shape respectively. When the length extension direction of the upper ventilation hole 210 and the lower ventilation hole 220 are consistent, the structural strength of the dehumidification box 200 at the top and bottom sides will be reduced. Therefore, in order to ensure the structural strength of the upper and lower sides of the dehumidification box 200, in this embodiment, the upper ventilation hole 210 is respectively provided with a plurality of holes in the horizontal and longitudinal directions, and the lower ventilation hole 220 is respectively provided with a plurality of holes in the horizontal and longitudinal directions. For example, the top side of the dehumidification box 200 is evenly divided into four parts with the center of the dehumidification box 200, and the extension directions of the upper ventilation holes 210 in two adjacent parts are different. A plurality of upper ventilation holes 210 are arranged in a horizontal and vertical arrangement, which ensures the air outlet on the top side of the dehumidification box 200 while better considering the structural strength of the top side of the dehumidification box 200. Similarly, a plurality of lower ventilation holes 220 are arranged in a horizontal and vertical arrangement, which ensures the air inlet on the bottom side of the dehumidification box 200 while better considering the structural strength of the bottom side of the dehumidification box 200.

[0036] When the top side of the base 100 is too close to the bottom dehumidification box 200, such as the air outlet 110 on the top side of the base 100 and the lower ventilation hole 220 of the bottom dehumidification box 200 are not completely opposite to each other, the airflow is difficult to be directly blown into the dehumidification box 200. Therefore, in order to ensure the supply of stable airflow into the dehumidification box 200, in this embodiment, the top side of the base 100 is concave downward to form a transition groove 120, and a plurality of upper ventilation holes 210 are respectively formed at the bottom of the transition groove 120. The transition groove 120 can form a space for air flow between the air inlet position of the bottom dehumidification box 200 and the base 100. When the airflow is blown upward from the base 100, it passes through the transition groove 120 and is dispersed to the plurality of lower ventilation holes 220 on the bottom side of the dehumidification box 200, and then enters the dehumidification box 200, thereby improving the uniformity of air entering the dehumidification box 200.

[0037] In the above embodiment, the dehumidification beads and other adsorbents are mainly dehumidified by blowing air from the fan 140. In order to further improve the dehumidification efficiency, in this embodiment, the top side of the base 100 is connected to an air guide sleeve 130, which is directly opposite to the air outlet of the fan 140. A heater 131 is connected to the air guide sleeve 130. When the fan 140 is blowing air, it passes through the air guide sleeve 130, and the airflow is heated by the heater 131 before being blown upward. The air guide sleeve 130 can make the heat generated by the heater 131 more concentrated, thereby improving the heating efficiency of the airflow. When the airflow is blown into the dehumidifier, the hot air is used to dry the adsorbents such as the dehumidification beads in the dehumidification box 200, further improving the dehumidification efficiency and quality.

[0038] When the dehumidifier box 200 is used alone, it can be directly placed for use, or directly hung for use. In this embodiment, the dehumidifier box 200 is connected with a hanging ear 300. When the dehumidifier is used alone, it can be hung on the structural member of the external device through the hanging ear 300, which is more convenient to use.

[0039] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
