Description

TECHNICAL FIELD

[0001] The utility model relates to air dehumidification technical field, especially a dehumidifier. BACKGROUND

[0002] The dehumidifier converts the moisture in the air into liquid water through condensation principle and collects it into the water tank. As the dehumidification work continues, the water level in the water tank will gradually rise. When the water tank is full, if the dehumidification is not stopped in time or the water tank is not emptied, it will cause the problem of water overflow. This not only causes waste of water resources, but also may cause damage to furniture, floor and other surrounding furniture of the dehumidifier, and even cause safety hazards.

[0003] In order to solve the problem of water overflow in the water tank, the existing dehumidifier usually has a water level indicator in the water tank. The water level indicator can float up and down with the water level to reflect the water level height in the water tank in real time, so as to remind the user to pay attention to and handle the water in the water tank in time.

[0004] However, in actual application, due to the complexity of the internal structure of the water tank and the limitation of the design of the water level indicating device itself, the water level indicating device is easily hindered in the process of floating up and down, which causes the water level indicator to be unable to smoothly move to the correct position, so as to accurately indicate the actual water level in the water tank. SUMMARY

[0005] One object of the utility model is to overcome at least one technical defect in the prior art and provide a dehumidifier.

[0006] A further object of the utility model is to ensure the smoothness of the floating of the floating member, so as to provide accurate water level indication.

[0007] Another further object of the utility model is to simplify the installation structure of the floating member and improve its installation efficiency and convenience.

[0008] Still another further object of the utility model is to prevent the floating member from floating too much and affecting the accuracy of water level indication.

[0009] In particular, the utility model provides a dehumidifier, which comprises a water tank and a water level display assembly arranged in the water tank, and the water level display assembly comprises:

[0010] The floating member comprises a floating rod and two floating caps, the floating rod extends transversely, and the two floating caps are connected to the two ends of the floating rod respectively to make the floating rod float up and down with the change of water level; and

[0011] The guide piece comprises two guide rails, vertical guide grooves are formed in the inner parts of the two guide rails respectively for guiding the up-and-down floating of the corresponding floating caps, vertical clearance openings are formed in the sides of the two guide rails close to each other for providing clearance space for the up-and-down floating of the floating rod.

[0012] Optionally, the top of the guide groove has a port, and the clearance opening extends downward from the top of the guide rail, so that the two floating caps are correspondingly installed in the two guide grooves from top to bottom.

[0013] Optionally, the height of the clearance opening is less than the height of the guide groove, so that the two floating caps are lifted upward when the floating rod falls to the lower edge of the clearance opening.

[0014] Optionally, the floating rod is a cylindrical rod, and the floating cap is spherical or ellipsoidal.

[0015] Optionally, in the axial direction of the floating rod, the ratio of the width of the floating cap to the width of the guide groove ranges from 1:1.2 to 1:2.5.

[0016] Optionally, the guide rail is a vertically extending U-shaped structure, which is fixedly buckled to the side wall of the water tank or integrally formed with the side wall of the water tank.

[0017] Optionally, the side wall of the water tank is formed with a vertically extending transparent window, which is used to show the up-and-down floating state of the floating rod during water level change.

[0018] Optionally, a preset interval is left between the bottom of the transparent window and the bottom of the water tank.

[0019] Optionally, the dehumidifier further comprises:

[0020] The shell has a mounting opening in the lateral direction, and the water tank is pullably assembled in the shell via the mounting opening.

[0021] Optionally, the water tank comprises a tank body and a tank cover buckled to the top of the tank body, and the tank cover is formed with a socket for the upward penetration of at least one guide rail.

[0022] The dehumidifier of the utility model, the water level display assembly of which comprises a floating piece and a guide piece, two floating caps of the floating piece are connected to the two ends of a floating rod respectively, and the floating rod can be better caused to float up and down with the change of water level. The guide piece comprises two guide rails, the guide grooves in the guide rails can accurately guide the up-and-down floating of the floating caps, and the clearance openings on the guide rails can ensure that the floating rod will not be hindered or stuck during floating. In this way, the smooth floating of the entire floating piece can be ensured, thereby providing accurate water level indication.

[0023] Further, the dehumidifier has the port design at the top of the guide groove and the extension of the clearance from the top of the guide rail downward, so that the floating member can be quickly installed from above the guide member. In actual installation, only the two floating caps need to be aligned with the guide groove ports and pushed in, and at the same time, the floating rod is smoothly slid from the clearance, so that the installation can be completed. This not only simplifies the installation structure, but also improves the installation efficiency, so that the whole installation process is more simple and convenient.

[0024] Further, the dehumidifier has the water tank including a tank body and a tank cover, and the tank cover is formed with a socket. When the tank cover is buckled on the top of the tank body, the guide rail below the socket can be penetrated upward.

Unless otherwise specifically limited, when a certain feature "includes or contains" a certain or certain features encompassed thereby, unless otherwise specifically described, it indicates that other features are not excluded and can further include other features.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0041] The present application provides a dehumidifier, Figure 1 is a schematic structure of the dehumidifier according to one embodiment of the present application, Figure 2 is a schematic exploded view of the cabinet 10 and the water tank 20 according to one embodiment of the present application.

[0042] As shown in Figure 1 and Figure 2 , the dehumidifier can generally include a cabinet 10 and a water tank 20.

[0043] Among them, the upper part of the front side, the upper part of the left side and the upper part of the right side of the cabinet 10 are collectively enclosed into a wide air inlet 110, so that the indoor air can enter the inside of the cabinet 10 more smoothly, and provide sufficient air source for the dehumidification process.

[0044] At the same time, the top of the cabinet 10 is formed with an air outlet 120, and the dry air treated by dehumidification can be uniformly released to the indoor space from the air outlet 120, and fully mixed and exchanged with the humid air in the room, so as to improve the dehumidification efficiency.

[0045] The lateral direction of the cabinet 10 has a mounting port 130, in the present embodiment, the mounting port 130 is located at the lower part of the front side of the cabinet 10, and the water tank 20 is pullably assembled in the cabinet 10 through the mounting port 130.

[0046] During the operation of the dehumidifier, the indoor humid air is sucked into the inside of the cabinet 10 through the air inlet 110, and after the condensation treatment, the dry air is blown out through the air outlet 120 at the top of the cabinet 10, so as to realize the effective reduction of indoor humidity. In this process, the humid air will condense into condensed water when it is cooled in the cabinet 10, and the water tank 20 serves as a collection container for the condensed water, which is used to safely and effectively store the condensed water.

[0047] Figure 3 is a schematic structure of the water tank 20 according to one embodiment of the present application, Figure 4 is a schematic exploded view of the water tank 20 according to one embodiment of the present application.

[0048] As shown in Figure 3 andFigure 4 As shown, the water tank 20 can include a tank body 210 and a tank cover 220, the tank body 210 is defined with a containing cavity, and the tank cover 220 is buckled on the top of the tank body 210. The tank cover 220 is provided with a water inlet 221, and the condensed water generated by the dehumidifier can be collected in the water tank 20 through the internal water collecting tray. In this way, the leakage and waste of the condensed water can be effectively avoided, and the collection efficiency of the condensed water can be improved.

[0049] In some embodiments of the present application, the water tank 20 further includes a handle 230, the handle 230 is in a U shape, and the two ends of the handle 230 are hinged to the tank body 210.

[0050] In the present embodiment, the main function of the handle 230 is to facilitate the user to easily pick up and move the water tank 20.

[0051] The U-shaped handle 230 is connected to the tank body 210, and the ends of the two arms of the handle 230 are hinged to the tank body 210, so that the handle 230 is rotatably connected to the tank body 210. The handle 230 is rotatably arranged to facilitate gripping the handle 230 when the tank body 210 needs to be tilted, or to rotate the handle 230 to the inside or one side of the tank body 210 when the water tank 20 does not need to be moved, thereby reducing the space occupied by the water tank 20.

[0052] In some embodiments of the present application, the handle 230 has a use position and a mounting position on its rotation route. When the handle 230 is in the use position, the two arms of the handle 230 are perpendicular to the horizontal plane. When the handle 230 is in the mounting position, the two arms of the handle 230 are parallel to the horizontal plane, and the top of the handle 230 is not higher than the top of the tank body 210.

[0053] In the present embodiment, when the water tank 20 is lifted by the handle 230, the tank body 210 exerts a downward pulling force on the handle 230 due to gravity, so as to make the two arms of the handle 230 perpendicular to the horizontal plane, so that the handle 230 is in the use position.

[0054] When the handle 230 is in the mounting position, the two arms of the handle 230 are parallel to the horizontal plane, and the top of the handle 230 is not higher than the top of the tank body 210, so that the handle 230 does not occupy additional vertical space, so that the water tank 20 is more compact when installed in the dehumidifier or other machines. Moreover, the design that the top of the handle 230 is not higher than the top of the tank body 210 also reduces the interference between the handle 230 and other objects.

[0055] In some embodiments of the present application, the handle 230 is rotatably connected to the inside of the tank body 210, and the center position of the handle 230 coincides with the projection of the center position of the tank body 210 on the horizontal plane.

[0056] In the embodiment, the handle 230 is completely inside the box body 210 when placed in the mounting position, avoiding the risk of accidental collision or tripping of the user, improving the safety of the user.

[0057] In some embodiments of the utility model, two vertical connecting plates 211 are arranged in the box body 210, the box cover 220 is provided with a connecting port 223 at the corresponding position of the connecting plate 211, and at least part of the two connecting plates 211 passes out of the connecting port 223 and is connected with the handle 230.

[0058] When assembling the water tank 20, the connecting port 223 on the box cover 220 is aligned with the connecting plate 211 on the box body 210, and then the box cover 220 is buckled on the box body 210, so that the connecting plate 211 extends upward out of the box cover 220, and finally the two ends of the handle 230 are mounted to the connecting plate 211.

[0059] Of course, the two connecting plates 211 can extend in the front-rear direction in the box body 210, the bottom of the connecting plate 211 is fixedly connected with the bottom wall of the box body 210, and the front side of the connecting plate 211 is fixedly connected with the front side wall of the box body 210. In this way, the structural strength of the entire box body 210 can be improved, so that the box body 210 is more solid and durable.

[0060] The height of the connecting plate 211 at the connecting port 223 can be higher than the height of the rest of the connecting plate 211. In this way, when the box cover 220 is buckled on the box body 210, the part of the connecting plate 211 at the connecting port 223 can be used to install the handle 230, and the rest of the connecting plate 211 can support the box cover 220 from the bottom of the box cover 220 to prevent the box cover 220 from sinking.

[0061] In addition, the box cover 220 can be provided with a drain port 222. In this way, the user can drain the condensed water in the water tank 20 without removing the box cover 220, reducing the complexity of the drainage operation.

[0062] In the embodiment, the front side of the box cover 220 has a gap, and when the box cover 220 is buckled on the box body 210, the side wall of the box cover 220 at the gap and the side wall of the box body 210 together enclose the above-mentioned drain port 222.

[0063] As mentioned above, as the dehumidification work continues, the water level in the water tank 20 will gradually rise. When the water tank 20 is full, if the dehumidification is not stopped in time or the water tank 20 is not emptied, the problem of water overflow will occur.

[0064] If the water overflows, not only will cause the waste of water resources, but also can cause damage to the dehumidifier around furniture, floor, etc., and even cause safety hazards. Or, the water tank 20 is actually not full, but due to the user to determine the water level, it may be too early to think that the water tank 20 is full and interrupt the operation of the dehumidifier, thereby affecting the dehumidification effect.

[0065] Although the prior art has installed a water level indicator for the water tank 20, the water level indicator is used to display the high and low of the water level with the change of the water level, but unfortunately, the water level indicator often encounters various obstacles, which causes it to be unable to smoothly float with the change of the water level, and thus cannot accurately reflect the actual water level in the water tank 20.

[0066] To solve the above problems, the dehumidifier of the utility model further comprises a water level display assembly, which is arranged in the water tank 20 and is used for allowing the user to know the water level in the water tank 20 at any time.

[0067] Figure 5 is a schematic structural view of the water tank 20 and the water level display assembly according to an embodiment of the utility model, Figure 6 is Figure 5 a schematic partial enlarged view of part A in FIG. Figure 7 is a schematic top view of the water tank 20 and the water level display assembly according to an embodiment of the utility model, Figure 8 is Figure 7 a schematic partial enlarged view of part B in FIG. Among them, Figure 5 and Figure 7 part C in FIG. hides the tank cover 220 of the water tank 20, so as to more clearly show the water level display assembly.

[0068] As shown in FIG. Figures 5 to 8 , the water level display assembly can comprise a floating piece 310 and a guide piece 320.

[0069] Among them, the floating piece 310 comprises a floating rod 311 and two floating caps 312, the floating rod 311 extends horizontally, and the two floating caps 312 are respectively connected to both ends of the floating rod 311, so as to cause the floating rod 311 to float up and down with the change of the water level.

[0070] The guide piece 320 comprises two guide rails 321, the inner parts of the two guide rails 321 are respectively formed with vertically extending guide grooves 322, which are used for guiding the respective corresponding floating caps 312 to float up and down, and the sides of the two guide rails 321 close to each other are respectively formed with vertically extending accommodation openings 323, which are used for providing an accommodation space for the floating rod 311 to float up and down.

[0071] The water level display assembly of the dehumidifier of the embodiment comprises a floating member 310 and a guide member 320, two floating caps 312 of the floating member 310 are connected to two ends of a floating rod 311 respectively, and the floating rod 311 can be better caused to float up and down with the change of the water level. The guide member 320 comprises two guide rails 321, guide grooves 322 in the guide rails 321 can accurately guide the floating caps 312 to float up and down, and the accommodation openings 323 on the guide rails 321 can ensure that the floating rod 311 does not appear any obstruction or jam during the floating process. In this way, the smooth floating of the whole floating member 310 can be ensured, and thus accurate water level indication can be provided.

[0072] In some embodiments of the utility model, the top of the guide groove 322 has a port 324, and the accommodation opening 323 extends downward from the top of the guide rail 321, so that the two floating caps 312 are correspondingly loaded into the two guide grooves 322 from top to bottom.

[0073] That is to say, the floating member 310 can be quickly installed from above the guide member 320. During actual installation, only the two floating caps 312 need to be aligned with the ports 324 of the guide grooves 322 and pushed in, and at the same time, the floating rod 311 is smoothly slid down from the accommodation opening 323, so that the installation is completed. This not only simplifies the installation structure, but also improves the installation efficiency, so that the whole installation process is more simple and convenient.

[0074] In some embodiments of the utility model, the height of the accommodation opening 323 is less than the height of the guide groove 322, so that the two floating caps 312 are lifted upward when the floating rod 311 falls to the lower edge of the accommodation opening 323.

[0075] It can be understood that the guide groove 322 is a running route specially designed for the floating cap 312, which starts from the bottom wall of the water tank 20 and extends upward. The two ends of the floating rod 311 pass through the accommodation opening 323 and are connected with the floating caps 312 inside the guide groove 322. The height of the accommodation opening 323 is specially set to be lower than that of the guide groove 322, which means that the lower edge of the accommodation opening 323 is actually located above the bottom wall of the water tank 20.

[0076] When the water tank 20 completes the drainage operation and has almost no condensate water or a very low water level, there is no need to display specific water level information. At this time, the floating rod 311 can naturally fall to the lower edge of the accommodation opening 323 and cannot continue to fall due to the obstruction of the lower edge, so that the floating rod 311 can generate a certain lifting force at this position, and then push the two floating caps 312 upward.

[0077] In this way, when the water level in the water tank 20 is low or completely empty, the floating cap 312 will not be in direct contact with the bottom wall of the water tank 20, but will be stably maintained at a certain height above the bottom wall of the water tank 20, so that the floating cap 312 is protected from potential pressure and wear. At the same time, in the case of low or completely empty water level in the water tank 20, the floating rod 311 will also be kept in a clear and non-misleading state for the user.

[0078] In the present embodiment, the floating rod 311 is a cylindrical rod, and the floating cap 312 is spherical or ellipsoidal. In this way, when the water level changes, the floating member 310 can follow the water level by smoothly floating or smoothly rolling, without being stuck, and can more timely reflect the actual water level height.

[0079] In some embodiments of the present application, the ratio of the width of the floating cap 312 to the width of the guide groove 322 along the axial direction of the floating rod 311 is in the range of 1:1.2 to 1:2.5. For example, 1:1.2, 1:1.5, 1:1.8, 1:2.0, 1:2.5, etc.

[0080] It can be understood that if the width of the guide groove 322 is exactly the same as the width of the floating cap 312, when the water level changes and the floating cap 312 floats, the floating cap 312 can be easily rubbed and hindered by the close contact with the side wall of the guide groove 322, thereby increasing the risk of being stuck. This not only affects the accuracy of the water level indication, but also can cause unnecessary wear to the floating cap 312. If the width of the guide groove 322 is too large, although it can reduce the possibility of the floating cap 312 being stuck to a certain extent, such a design will result in a less compact structure, occupy more space, and increase the manufacturing cost and installation difficulty.

[0081] Therefore, in the embodiments of the present application, by limiting the ratio of the width of the floating cap 312 to the width of the guide groove 322 to be in the range of 1:1.2 to 1:2.5, it can be ensured that the width of the guide groove 322 will neither be too narrow to cause the floating cap 312 to be stuck, nor be too spacious to affect the compactness and aesthetics of the structure.

[0082] In some embodiments of the present application, the guide rail 321 is a vertically extending U-shaped structure, which is fixedly connected to the side wall of the water tank 20 or integrally formed with the side wall of the water tank 20.

[0083] Specifically, please refer to Figure 5 and 6 , both guide rails 321 are U-shaped and arranged spaced apart from each other. For the left guide rail 321, a vertically downward extending gap 323 is formed in the position close to the front side of the tank body 210 on the right side wall thereof. For the right guide rail 321, a vertically downward extending gap 323 is formed in the position close to the front side of the tank body 210 on the left side wall thereof.

[0084] When the water level in the tank 210 exceeds the lower edge of the clearance 323, the condensed water will enter the guide groove 322 from the clearance 323. In this way, as the condensed water continues to increase, the water level in the guide groove 322 will be consistent with the water level in the tank 210.

[0085] The left and right clearances 323 not only allow the two ends of the float rod 311 to pass through the guide rail 321 and be connected with the float cap 312 in the guide groove 322, but also provide a clearance for the up-and-down floating of the float rod 311, so that the float rod 311 is not blocked during the up-and-down floating.

[0086] In some embodiments of the present application, the side wall of the water tank 20 can be formed with a vertically extending transparent window 212, which is used to present the up-and-down floating state of the float rod 311 during the water level change.

[0087] Specifically, the transparent window 212 can be located on the front side wall of the water tank 20, and is made of a material with high light transmittance, such as glass or transparent plastic, to ensure that the user can clearly see the inside of the water tank 20 and meet the user's visual clarity requirements.

[0088] The height of the transparent window 212 can be set to exceed the maximum distance that the float rod 311 can reach during the up-and-down floating, which can ensure that the entire floating track of the float rod 311 can be fully displayed in the transparent window 212. In this way, the user can easily capture the dynamic of the float rod 311 through the transparent window 212, and thus accurately evaluate the current water level.

[0089] The height of the transparent window 212 can be set to be less than the width of the float rod 311, and only needs to ensure that the middle section of the float rod 311 can be observed. Such a design not only meets the observation requirements, but also effectively controls the material cost, reflecting the practicality and economy of the design.

[0090] A predetermined gap can be left between the bottom of the transparent window 212 and the bottom of the water tank 20. For example, the lower edge of the transparent window 212 can be slightly lower than the lower edge of the clearance 323. When the water level in the water tank 20 is low or completely empty, there is no need to specially prompt the user.

[0091] In this particular situation, the float rod 311 will smoothly fall to the lower edge of the clearance 323 and maintain a static equilibrium position. At this time, the user can easily capture the float rod 311 through the lower area of the transparent window 212, and thus indirectly understand the current water level of the water tank 20.

[0092] Such design not only avoids visual redundancy or cost increase due to the excessive length of the transparent window 212, but also utilizes the static position of the floating rod 311 as an indirect indication of low water level or no water state, which not only meets the observation needs of the user, but also takes into account the aesthetics.

[0093] In some embodiments of the present application, the tank cover 220 of the water tank 20 is formed with a socket 224 through which at least one guide rail 321 passes upward.

[0094] When the tank cover 220 is buckled on the top of the tank body 210, the guide rail 321 below the socket 224 can pass upward. In this way, when the water level rises to a certain extent, the floating member 310 will be blocked by the tank cover 220, even in the case of abnormal water level rise, it can ensure that the floating member 310 will not float excessively, which can effectively prevent the floating member 310 from accidentally coming out of the guide rail 321 or the water tank 20.

[0095] In a specific example, the upper end of the guide rail 321 can be provided with a step, i.e. the part corresponding to the socket 224 is higher than the rest, when the tank cover 220 is buckled on the tank body 210, the guide rail 321 only passes upward through the socket 224 corresponding to the socket 224, and the rest supports the tank cover 220 from the bottom of the tank cover 220.

[0096] In another specific example, the upper end of the guide rail 321 can also pass upward through the socket 224 as a whole, and the passing height can be set according to actual needs.

[0097] The embodiments of the present application utilize the tank cover 220 as an upper limiting device of the floating member 310, when the tank cover 220 is in a closed state, a block is naturally formed, which limits the range of upward movement of the floating member 310, and avoids the accidental falling of the floating member 310 from the guide member 320 due to excessive rising.

[0098] At the same time, when the user needs to install or replace the floating member 310, it is only necessary to simply remove the tank cover 220, and then the floating member 310 can be placed downward into the guide member 320, which not only reduces the installation difficulty, but also enhances the use reliability of the floating member 310.

[0099] At this point, those skilled in the art should realize that although the present application has been shown and described in detail in the above, many other variants or modifications conforming to the principles of the present application can be directly determined or deduced according to the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
