Description

TECHNICAL FIELD

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

[0002] At present, most dehumidifiers are equipped with a water tank for collecting condensate water generated during operation. However, when the water tank is full of water, if the user fails to turn off the dehumidifier or empty the water tank in time, the dehumidifier will continue to run, eventually causing the condensate water in the water tank to overflow. This overflow not only makes the ground slippery, increasing the risk of falling and other safety risks, but also can cause damage to the dehumidifier itself, such as causing a short circuit in the circuit or corrosion of the components, thereby shortening the service life of the equipment.

[0003] Although some dehumidifiers on the market have adopted basic water level indication methods, such as using a water tank made of transparent material or setting clear water level graduation lines on the outside of the water tank, so that the user can directly observe the water level in the water tank.

[0004] However, these methods still require the user to actively observe and remember, so they cannot completely eliminate the risk of condensate water overflow. Especially in the case of a busy or forgetful user, it is easy to miss the opportunity to empty the water tank in time. SUMMARY

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

[0006] A further object of the present utility model is to actively remind the user to clean the water tank to avoid water overflow.

[0007] Another further object of the present utility model is to limit the floating assembly to avoid excessive floating of the floating assembly.

[0008] Still another further object of the present utility model is to optimize the structure of the guide piece to make the floating assembly easy to install and replace.

[0009] In particular, the present utility model provides a dehumidifier, comprising:

[0010] a water tank, which has a receiving cavity for collecting condensate water formed therein, and a guide groove extending vertically and communicating with the receiving cavity;

[0011] a floating assembly arranged in the guide groove, which has a first position floating to the top of the guide groove and a second position falling to the bottom of the guide groove; and

[0012] a water level switch arranged on the outside of the water tank and set at a height lower than the center plane of the guide groove in the transverse direction, for triggering a full tank prompt signal when the floating assembly floats to the first position.

[0013] Optionally, the floating assembly comprises a float and a magnetic element, the magnetic element being completely wrapped in or at least partially embedded in the float, for following the float up and down.

[0014] Optionally, a guide is arranged in the water tank, the guide extending along the height direction of the water tank and being cooperated with the side wall of the water tank to form the guide groove.

[0015] The guide is provided with a communication port, the communication port allowing the condensed water in the accommodating cavity to flow into the guide groove, so that the water level height in the guide groove is consistent with the water level height in the accommodating cavity.

[0016] Optionally, the top of the guide is provided with a stopper, the stopper being used to stop the floating assembly from above when the floating assembly floats to the first position.

[0017] Optionally, the communication port is located on the side of the guide facing the water level switch, and the stopper extends from the upper edge of the communication port towards the water level switch.

[0018] Optionally, the width of the communication port gradually decreases from bottom to top; and

[0019] The guide is provided with a force relieving port extending downward on both sides of the stopper.

[0020] Optionally, the guide has a bottom plate, the bottom plate being located above the bottom wall of the water tank, and the height between the bottom plate and the bottom wall of the water tank is 1 / 4-1 / 2 of the height of the water tank.

[0021] Optionally, the guide further has a support plate, the support plate extending upward from the bottom wall of the water tank to the bottom plate to support the bottom plate.

[0022] Optionally, the dehumidifier further comprises:

[0023] A casing, the casing being laterally provided with a mounting port, the water tank being pullably assembled in the casing via the mounting port.

[0024] Optionally, the guide groove is formed in the insertion end of the water tank, and the water level switch is fixed in the casing.

[0025] The dehumidifier of the utility model, the floating assembly has the first position of floating to the top of the guide groove and the second position of falling to the bottom of the guide groove, because the setting height of the water level switch is lower than the center plane of the guide groove along the transverse direction, the distance between the first position and the water level switch is greater than the distance between the second position and the water level switch. With the working of the dehumidifier, the water level in the water tank gradually rises, and the floating assembly will also gradually float from the second position to the first position, that is, the top of the guide groove. At this time, the distance between the floating assembly and the water level switch is far, and it can trigger the water level switch to send a full water prompt signal, thereby actively reminding the user that the water tank has approached the full water state, effectively avoiding the full water overflow.

[0026] Further, the dehumidifier of the utility model, the top of the guide piece is provided with a stop piece, the stop piece can stop the floating assembly from above when the floating assembly floats to the first position. In the case of continuous rise of the water level, it can be ensured that the floating assembly can finally stay stably at the first position, avoiding the floating assembly from accidentally falling out of the guide groove of the guide piece due to too high water level or too large buoyancy, thereby improving the stability and safety of the floating assembly.

[0027] Further, the dehumidifier of the utility model, the width of the communication port gradually decreases from bottom to top, and the guide piece is provided with a downward extending unloading port on both sides of the stop piece. When it is necessary to install or replace the floating assembly, the user only needs to gently move the stop piece, and due to the existence of the unloading port, the top size of the guide groove will be correspondingly increased, thereby forming a more spacious entrance. This can simplify the process of entering and exiting the floating assembly, so that the user can easily put or take out the floating assembly from the guide groove without effort or the help of additional tools.

In order to illustrate the structure of the device, some of the drawings of the present application are illustrated in a perspective form.

[0043] In the description of the present embodiment, it should be understood that the term "a plurality of" means at least two, for example, two, three, etc. Unless otherwise specifically limited, when a certain feature "includes or contains" a certain or certain features covered thereby, unless otherwise specifically described, it indicates that other features and can further include other features.

[0044] In the description of the present embodiment, the description of the terms "one embodiment", "some embodiments", "some examples", "one example" and the like means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. 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.

[0045] The present application provides a dehumidifier, Figure 1 is a schematic structure of a dehumidifier according to an embodiment of the present application, Figure 2 is a schematic exploded view of the casing 10 and the water tank 20 according to an embodiment of the present application.

[0046] As Figure 1 and Figure 2 shown, the dehumidifier can generally include a casing 10 and a water tank 20.

[0047] 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 casing 10 are collectively enclosed into a wide air inlet 110, so that the indoor air can enter the casing 10 more smoothly, and provide sufficient air source for the dehumidification process.

[0048] At the same time, the top of the casing 10 is formed with an air outlet 120, and the dry air treated by the dehumidification process can be uniformly released to the indoor space from the air outlet 120, and fully mixed and exchanged with the indoor humid air, thereby improving the dehumidification efficiency.

[0049] The side of the casing 10 has a mounting port 130. In the embodiment, the mounting port 130 is located at the lower part of the front side of the casing 10. The water tank 20 is pullably assembled in the casing 10 via the mounting port 130.

[0050] During the operation of the dehumidifier, the humid air in the room is sucked into the casing 10 through the air inlet 110, and after condensation treatment, the dry air is blown out through the air outlet 120 at the top of the casing 10, so as to effectively reduce the humidity in the room. In this process, the humid air will condense into condensed water when it is cooled in the casing 10. The water tank 20 serves as a collection container for the condensed water, which is used to safely and effectively store the condensed water.

[0051] Figure 3 FIG. 2 is a schematic structural diagram of the water tank 20 according to an embodiment of the present application, Figure 4 FIG. 3 is a schematic exploded view of the water tank 20 according to an embodiment of the present application.

[0052] As shown in Figure 3 and Figure 4 , the water tank 20 can include a tank body 210 and a tank cover 220, 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 preliminarily collected by the internal water collecting disc 250 and then collected into the tank body 210 from the water inlet 221. 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.

[0053] The water tank 20 can further include a handle 230, and the handle 230 is in a U shape and is hingedly connected to the tank body 210 at both ends. The main function of the handle 230 is to facilitate the user to easily pick up and move the water tank 20, so as to clean the water tank 20 in time when the water tank 20 is full.

[0054] The tank cover 220 can be provided with a water outlet 222. In this way, the user can drain the condensed water in the water tank 20 without removing the tank cover 220, thereby reducing the complexity of the water draining operation.

[0055] For example, the front side of the tank cover 220 has a gap, and when the tank cover 220 is buckled on the tank body 210, the side wall of the tank cover 220 at the gap and the side wall of the tank body 210 together form the water outlet 222 described above.

[0056] As mentioned above, although some dehumidifiers on the market have adopted a basic water level indication method, such as using a water tank 20 made of transparent material or setting clear water level graduation lines on the outside of the water tank 20, so that the user can directly observe the water level in the water tank 20.

[0057] However, these methods still require the user to actively observe and remember, and thus cannot completely eliminate the risk of condensate overflow. In particular, in the case of a busy user or forgetfulness, it is easy to miss the opportunity to empty the water tank 20 in time.

[0058] To solve the above problems, the dehumidifier optimizes the structure of the water tank 20, and configures the water tank 20 with a floating assembly 30 and a water level switch 40.

[0059] Figure 5 is a schematic exploded view of the water tank 20 and the water pan 250 according to an embodiment of the present application, Figure 6 is a schematic internal structure view of the water tank 20 according to an embodiment of the present application, Figure 7 is Figure 6 is a schematic enlarged view of part A, Figure 8 is a schematic state view of the floating assembly 30 according to an embodiment of the present application, Figure 9 is a schematic state view of the floating assembly 30 according to another embodiment of the present application.

[0060] As shown in Figures 5 to 9 , the water tank 20 is formed with a containing cavity 211 and a guide groove 241, wherein the containing cavity 211 is used to collect condensate water, and the guide groove 241 extends vertically and communicates with the containing cavity 211. In this way, during operation of the dehumidifier, the condensate water in the containing cavity 211 can enter the guide groove 241, so that the water level height in the groove is consistent with the water level height in the containing cavity 211.

[0061] The floating assembly 30 is arranged in the guide groove 241, and has a first position of floating to the top of the guide groove 241 and a second position of falling to the bottom of the guide groove 241. When the floating assembly 30 is in the first position, it means that the water level in the water tank 20 is high, and the water tank 20 needs to be cleaned in time; when the floating assembly 30 is in the second position, it means that the water level in the water tank 20 is low, and the water tank 20 does not need to be cleaned in a short time.

[0062] The water level switch 40 is arranged on the outer side of the water tank 20, and the setting height of the water tank 20 is lower than the center plane of the guide groove 241 in the transverse direction, and is used to trigger a full water prompt signal when the floating assembly 30 floats to the first position.

[0063] The dehumidifier of the embodiment has the water level switch 40 arranged at a position lower than the center of the guide groove 241 in the lateral direction, so that the distance between the first position and the water level switch 40 is greater than the distance between the second position and the water level switch 40. As the dehumidifier operates, the water level in the water tank 20 gradually rises, and the floating assembly 30 gradually floats from the second position to the first position, i.e., the top of the guide groove 241. At this time, the floating assembly 30 is far away from the water level switch 40, and the water level switch 40 can be triggered to send a water full signal, thereby actively reminding the user that the water tank 20 is close to the water full state, and effectively avoiding the water full overflow.

[0064] In an optional embodiment, the floating assembly 30 can include a float 310 and a magnetic element 320, and the magnetic element 320 can be completely wrapped in the float 310 or at least partially embedded in the float 310, for following the float 310 up and down.

[0065] For example, the float 310 can be a flat cylindrical shape with the axis in the horizontal direction, and the magnetic element 320 can also be a flat cylindrical shape with the axis in the horizontal direction. The magnetic element 320 is coaxially arranged with the float 310, and the float 310 completely wraps the magnetic element 320, or the center of the float 310 is provided with a through hole, and the size of the through hole is matched with the size of the magnetic element 320, and the magnetic element 320 is inserted into the float 310 from the through hole.

[0066] It can be understood that, in the case that the amount of condensate water is sufficient, the float 310 will drive the magnetic element 320 to be in a floating state.

[0067] In the embodiment, when the float 310 and the magnetic element 320 are in the floating state, the horizontal plane where the axis of the magnetic element 320 is located will coincide with the water surface of the condensate water.

[0068] In other embodiments, when the float 310 and the magnetic element 320 are in the floating state, the horizontal plane where the axis of the magnetic element 320 is located can also be lower or higher than the water surface of the condensate water. The specific arrangement can be made according to actual needs.

[0069] In an optional embodiment, the magnetic element 320 can be a magnet, and the water level switch 40 can be a Hall switch. When the floating assembly 30 is in the second position, the distance between the magnet and the Hall switch is less than or equal to the effective magnetic induction distance of the Hall switch; when the floating assembly 30 is in the first position, the distance between the magnet and the Hall switch is greater than the effective magnetic induction distance of the Hall switch.

[0070] In this way, as the condensate water continues to accumulate, the floating assembly 30 will float with the water level, and before reaching the first position, the Hall switches can all sense the magnet, so that they are in the on state. At this time, the Hall switches send a safety signal, and correspondingly, the dehumidifier continues to run, does not emit a prompt sound, and the indicator light is always green. When the floating assembly 30 reaches the first position, the Hall switches will no longer be able to sense the magnet, so that they are in the off state. At this time, the Hall switches send a prompt signal, and correspondingly, the dehumidifier stops running, emits a prompt sound, and the indicator light is always red.

[0071] In the present embodiment, the water tank 20 is provided with a guide 240 extending along the height direction of the water tank 20, and the guide 240 and the side wall of the water tank 20 together enclose a guide groove 241.

[0072] When the floating assembly 30 is placed inside the guide groove 241, in order to ensure that it can smoothly rise or fall with the water level, a certain space interval should be maintained between the outer edge of the floating assembly 30 and the inner wall of the guide groove 241, so as to avoid that impurities or particulate matter possibly existing inside the water tank 20 hinder or jam the movement of the floating assembly 30.

[0073] The guide 240 can be provided at the insertion end of the water tank 20, and the water level switch 40 can be fixed in the casing 10.

[0074] In the present embodiment, the guide 240 is specifically located at the right side of the insertion end of the water tank 20. The water level switch 40 is fixed to the back side of the water receiving tray 250. After the water tank 20 is inserted into the casing 10, the guide 240 and the water level switch 40 are opposite to each other. In this way, when the condensate water in the water tank 20 flows into the guide groove 241 and drives the floating assembly 30 (which contains the magnetic element 320) to rise or fall, the water level switch 40 can accurately sense the position change of the magnetic element 320.

[0075] The guide 240 is provided with a communication port 242, which allows the condensate water in the containing cavity 211 to flow into the guide groove 241, so that the water level height in the guide groove 241 is consistent with that in the containing cavity 211. In this way, the water level in the guide groove 241 can accurately reflect the water level height in the containing cavity 211 in real time, and the position change of the floating assembly 30 in the guide groove 241 can accurately reflect the change of the water level in the water tank 20.

[0076] In an optional embodiment, the top of the guide 240 is provided with a stopper 243 for stopping the floating assembly 30 from above when it floats to the first position.

[0077] In the case of continuous water level rise, the stopper 243 can ensure that the floating assembly 30 can eventually stay stably in the first position, avoiding the floating assembly 30 from accidentally coming out of the guide groove 241 of the guide 240 due to excessively high water level or excessively large buoyancy, thus improving the stability and safety of the floating assembly 30.

[0078] In the present embodiment, the communication port 242 is located on the side of the guide 240 facing the water level switch 40, and the stopper 243 extends from the upper edge of the communication port 242 towards the water level switch 40.

[0079] The width of the communication port 242 can gradually decrease from bottom to top, and the guide 240 can be provided with a force relief port 244 extending downward on each side of the stopper 243.

[0080] When it is necessary to install or replace the floating assembly 30, the user only needs to gently move the stopper 243, and due to the presence of the force relief port 244, the top size of the guide groove 241 will correspondingly increase, thus forming a more spacious entrance. This can simplify the process of entering and exiting the floating assembly 30, so that the user can easily put or take out the floating assembly 30 from the guide groove 241 without having to exert force or use additional tools.

[0081] In an optional embodiment, the guide 240 has a bottom plate 245, which is located above the bottom wall of the water tank 20 and has a height of 1 / 4 to 1 / 2 of the height of the water tank 20 between the bottom wall of the water tank 20. For example, 1 / 4, 1 / 3, 1 / 2, etc.

[0082] Firstly, when the water level in the water tank 20 is lower than the bottom plate 245, no condensed water will accumulate in the guide groove 241. At this time, the floating assembly 30 will stay in its initial position, i.e., the second position. In this state, the water level switch 40 will remain in a conducting state, the dehumidifier can operate normally, and the indicator light will turn green, conveying to the user that the dehumidifier is in a normal working state.

[0083] Only when the water level in the water tank 20 rises above the height of the bottom plate 245, the floating assembly 30 will start to float upwards with the rise of the water level. This can effectively reduce the moving distance of the floating assembly 30, thus prolonging its service life and reducing the wear caused by frequent movement. At the same time, it also makes the water level monitoring more accurate and efficient, because the floating assembly 30 only moves in the range where the water level needs to be monitored.

[0084] In an optional embodiment, the guide 240 also has a support plate 246, which extends upward from the bottom wall of the water tank 20 to the bottom plate 245 to support the bottom plate 245.

[0085] Specifically, the number of support plates 246 can be two, and the two support plates 246 are arranged left and right. The upper end of each support plate 246 is fixedly connected with the bottom plate 245, and the lower end is fixedly connected with the bottom wall of the water tank 20. At the same time, the rear side of the support plate 246 is fixedly connected with the rear side wall of the water tank 20. This all-around fixed mode ensures that the support plate 246 can stably support the bottom plate 245, and improves the structural stability of the guide 240.

[0086] Further, the guide 240 can be integrally formed with the tank body 210 of the water tank 20. Through integral molding, the connection between the guide 240 and the tank body 210 of the water tank 20 is more closely, reducing the risk of failure caused by loose or damaged connection.

[0087] At this point, those skilled in the art should realize that although the present application has been shown and described in detail in this paper, many other variants or modifications conforming to the principles of the present application can be directly determined or deduced according to the content disclosed in 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.
