Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to a water leakage prevention device and a dehumidifier with the water leakage prevention device. Background Art

[0002] With the improvement of living standards, dehumidifiers have become a necessity for many families. A dehumidifier is a device that reduces humidity by sucking in moist air and passing it through a heat exchanger inside it, and discharges the condensed water produced during the dehumidification process.

[0003] In a typical dehumidifier structure, a water tray is placed above the water tank, allowing the condensed water to flow into the water tray along the surface of the heat exchanger, and finally discharged to the water tank through the water outlet of the water tray. When the condensed water in the water tank accumulates more and more until an alarm is sounded, the condensed water in the water tank needs to be emptied. The general treatment method is to directly remove the water tank from under the water tray, and then pour out the condensed water. During this process, there is no water tank under the water tray, and the accumulated water in the water tray will flow out from the water outlet of the water tray, causing the ground to be wet, affecting the user experience and polluting the environment.

[0004] In order to prevent the accumulated water from leaking out of the water outlet of the water receiving tray when the water tank is taken out to pour out the condensed water, a dehumidifier is currently provided with a sealing structure on the water receiving tray. When the water tank is taken out, the sealing member automatically seals the water outlet of the water receiving tray under the action of the counterweight block to prevent the accumulated water in the water receiving tray from leaking out. When the water tank is installed, the slope on the water tank presses against the toggle part, and the toggle part rotates, so that the end of the rotating arm is tilted, driving the sealing member upward, and the water outlet of the water receiving tray is opened to achieve normal drainage.

[0005] However, when the water tank of the above-mentioned existing dehumidifier is taken out, the seal falls down under the action of the deadweight of the counterweight and the seal to seal the water outlet of the water receiving tray. However, the accumulated water in the water receiving tray has a certain resistance to the seal, which may easily cause the seal to fail to completely fall into the water outlet for sealing, thereby affecting the sealing and anti-leakage effect. In addition, the counterweight, seal and rotating arm of the above-mentioned existing dehumidifier are all located inside the water receiving tray. When the water outlet of the water receiving tray is opened to achieve normal drainage, the counterweight, seal and rotating arm located in the water receiving tray hinder the flow rate of condensed water discharged from the water outlet, thereby affecting the drainage rate of the water outlet. Utility Model Content

[0006] In order to achieve the first purpose of the utility model, the utility model provides a water leakage prevention device which has a better sealing and water leakage prevention effect on the water outlet and increases the drainage rate of the water outlet, thereby improving the user experience.

[0007] In order to achieve the second purpose of the utility model, the utility model provides a dehumidifier with the above-mentioned anti-leakage device.

[0008] To achieve the first object of the present utility model, the present utility model provides a water leakage prevention device, which includes a water receiving tray, a rotating cover, an elastic member and an electromagnetic member. The water receiving tray is provided with a water outlet. The rotating cover is rotatably hinged outside the water outlet. An elastic pad is arranged on the side of the rotating cover close to the water outlet. The elastic member forces the rotating cover to rotate away from the water outlet, so that the elastic pad moves away from the water outlet to open the water outlet. A magnetic member is arranged on the rotating cover. The electromagnetic member is arranged outside the water outlet and can be magnetized when energized to adsorb with the magnetic member, so that the elastic pad presses against the water outlet to seal the water outlet.

[0009] As can be seen from the above solution, when the water tank is assembled and placed in the accommodating cavity of the casing to receive the drainage from the water outlet of the upper water leakage prevention device, the electromagnetic member of the water leakage prevention device is not energized or the direction of the energized current changes, so that the electromagnetic member cannot adsorb the magnetic member on the rotating cover. Thus, the elastic member forces the rotating cover to rotate away from the water outlet, so that the elastic pad moves away from the water outlet to open the water outlet, and the condensed water collected in the water receiving tray is smoothly discharged into the accommodating cavity of the water tank through the water outlet. When it is necessary to remove the water tank from the accommodating cavity of the casing to pour out the condensed water, the electromagnetic member of the water leakage prevention device is energized to be magnetized or the direction of the energized current changes, so that the electromagnetic member adsorbs with the magnetic member on the rotating cover. Thus, the elastic pad on the rotating cover presses against the water outlet to seal the water outlet. Since the elastic pad has the ability of elastic deformation, during the stable adsorption process between the electromagnetic member and the magnetic member on the rotating cover, the elastic pad can be tightly elastically sealed at the water outlet, making the water leakage prevention effect of the water outlet better.

[0010] Relatively speaking, the accumulated water in the water receiving tray of the existing dehumidifier has a certain resistance to the seal, which easily causes the seal to fail to completely fall into the water outlet under its own weight and the weight of the counterweight, thus affecting the water leakage prevention effect of the seal. The water leakage prevention device of the present utility model can accurately adsorb the rotating cover to rotate towards the water outlet and stably cover the water outlet by controlling the electromagnetic member to be magnetized when energized to adsorb with the magnetic member. And the elastic pad on the rotating cover can tightly elastically press against the water outlet to stably seal the water outlet, making the water leakage prevention effect of the water outlet better, thereby improving the user experience. Moreover, relatively speaking, the counterweight, the seal and the rotating arm of the existing dehumidifier are all located inside the water receiving tray, which hinders the flow rate of the condensed water discharged from the water outlet, thus affecting the drainage rate of the water outlet. The rotating cover, the elastic pad, the magnetic member, the elastic member and the electromagnetic member of the water leakage prevention device of the present utility model are all arranged outside the water receiving tray and the water outlet. When the electromagnetic member of the water leakage prevention device is not energized or the direction of the energized current changes, the elastic member forces the rotating cover to rotate away from the water outlet and reset, so that the elastic pad moves away from the water outlet to open the water outlet. Thus, the water outlet can drain smoothly and quickly, improving the drainage rate of the water outlet, thereby improving the user experience.

[0011] A further solution is that a water outlet channel is connected and communicated below the water receiving tray. The water outlet channel extends in the horizontal direction, and the water outlet is located at the open end of the water outlet channel away from the water receiving tray; a flow blocking plate is convexly arranged on the inner wall of the lower end of the water outlet channel, and the flow blocking plate is arranged close to the water outlet; and / or, a buffer plate is arranged below the water outlet channel, the buffer end of the buffer plate protrudes out of the water outlet, and a buffer groove is formed on the side surface of the buffer end of the buffer plate close to the water outlet, and the buffer groove penetrates through the buffer end of the buffer plate.

[0012] A further solution is that the electromagnetic part forms different magnetic poles when passing through currents in different directions, so that the electromagnetic part adsorbs or repels the magnetic part.

[0013] A further solution is that an installation groove is formed through the rotating cover. An installation column protrudes from the side surface of the elastic pad away from the water outlet. A snap cap is arranged at one end of the installation column away from the elastic pad. The snap cap can pass through the installation groove and be hooked on the side surface of the rotating cover away from the water outlet, and the installation column is located in the installation groove; and / or, the elastic pad is a rubber pad.

[0014] A further solution is that a plurality of through grooves are formed through the snap cap in the axial direction of the installation column. The plurality of through grooves are distributed in the circumferential direction of the snap cap, and each through groove penetrates through the outer peripheral wall of the snap cap.

[0015] A further solution is that a stepped groove is formed on the side surface of the rotating cover close to the water outlet. The elastic pad is located in the stepped groove, and a stepped boss adapted to the inner peripheral wall of the stepped groove protrudes from the outer peripheral wall of the elastic pad.

[0016] A further solution is that the elastic part is a torsion spring. A shaft rod is arranged on the water receiving tray. The rotating cover is rotatably hinged on the shaft rod. The spring coil of the torsion spring is sleeved on the shaft rod, and the two torsion arms of the torsion spring are respectively pressed between the rotating cover and the water receiving tray; and / or, the water receiving tray is provided with a limiting surface, and the side surface of the rotating cover away from the water outlet can abut against the limiting surface to limit the rotation angle of the rotating cover away from the water outlet.

[0017] A further solution is that a hook is arranged on the end surface of the rotating cover close to the water outlet, and the hook can be rotatably hooked on the shaft rod.

[0018] To achieve the second object of the present utility model, the present utility model provides a dehumidifier, which includes a water tank and a water leakage prevention device.

[0033] The present utility model will be further described below in conjunction with the drawings and embodiments. Detailed Description of the Preferred Embodiments

[0034] Refer to Figures 1 to 13, this embodiment discloses a dehumidifier, which includes a casing 11, a water tank 16 and a water leakage prevention device. The water leakage prevention device is located inside the casing 11, and the water tank 16 is detachably placed in the accommodation cavity of the casing 11, so that the water tank 16 is detachably placed below the water leakage prevention device.

[0035] Among them, the water leakage prevention device in this embodiment includes a water receiving tray 12, a rotating cover 130, an elastic member and an electromagnetic member 127. The water receiving tray 12 is provided with a water outlet 122. The rotating cover 130 is rotatably hinged outside the water outlet 122. An elastic pad 131 is provided on the side of the rotating cover 130 close to the water outlet 122. The elastic member forces the rotating cover 130 to rotate away from the water outlet 122, so that the elastic pad 131 moves away from the water outlet 122 to open the water outlet 122.

[0036] Moreover, a magnetic member 132 is provided on the rotating cover 130 of this embodiment. The electromagnetic member 127 is arranged outside the water outlet 122 and can be magnetized when electrified to adsorb with the magnetic member 132, so that the elastic pad 131 presses against the water outlet 122 to seal the water outlet 122.

[0037] When the water tank 16 is assembled and placed in the accommodation cavity of the casing 11 to receive the drainage from the water outlet 122 of the upper water leakage prevention device, the electromagnetic member 127 of the water leakage prevention device is not electrified or the direction of the electrified current changes, so that the electromagnetic member 127 cannot adsorb the magnetic member 132 on the rotating cover 130. Thus, the elastic member forces the rotating cover 130 to rotate away from the water outlet 122, so that the elastic pad 131 moves away from the water outlet 122 to open the water outlet 122. Then, the condensed water collected in the water receiving tray 12 is smoothly discharged into the accommodation cavity of the water tank 16, as Figures 11 to 13 shown.

[0038] When it is necessary to remove the water tank 16 from the accommodation cavity of the casing 11 to pour out the condensed water, the electromagnetic member 127 of the water leakage prevention device is electrified to be magnetized or the direction of the electrified current changes, so that the electromagnetic member 127 adsorbs with the magnetic member 132 on the rotating cover 130. Thus, the elastic pad 131 on the rotating cover 130 presses against the water outlet 122 to seal the water outlet 122, as Figure 2 and Figure 3 shown. Since the elastic pad 131 has the ability of elastic deformation, during the stable adsorption process between the electromagnetic member 127 and the magnetic member 132 on the rotating cover 130, the elastic pad 131 can be tightly elastically sealed at the water outlet 122, making the sealing and water leakage prevention effect of the water outlet 122 better.

[0039] The accumulated water in the water receiving tray of the existing dehumidifier has a certain resistance to the seal, which easily causes the seal to fail to completely fall into the water outlet under the action of its own weight and the weight of the counterweight, thus affecting the sealing and water leakage prevention effect. The water leakage prevention device of this embodiment can accurately adsorb and rotate the rotating cover 130 to rotate towards the water outlet 122 and stably cover the water outlet 122 by controlling the electromagnetic part 127 to be energized and magnetized to adsorb the magnetic part 132. Moreover, the elastic pad 131 on the rotating cover 130 can tightly and elastically press against the water outlet 122 to stably seal the water outlet 122, making the sealing and water leakage prevention effect of the water outlet 122 better, thereby improving the user experience. And, relative to the existing dehumidifier, the counterweight, seal, and rotating arm are all located inside the water receiving tray, which hinders the flow rate of the condensed water discharged from the water outlet, thus affecting the drainage rate of the water outlet. The rotating cover 130, elastic pad 131, magnetic part 132, elastic part, and electromagnetic part 127 of the water leakage prevention device of this embodiment are all arranged outside the water receiving tray 12 and the water outlet 122. When the electromagnetic part 127 of the water leakage prevention device is not energized or the direction of the energized current changes, the elastic part forces the rotating cover 130 to rotate away from the water outlet 122 and reset, so that the elastic pad 131 moves away from the water outlet 122 to open the water outlet 122. Thus, the water outlet 122 can drain smoothly and quickly, improving the drainage rate of the water outlet 122 and avoiding the overflow of excessive accumulated water in the water receiving tray 12, thereby improving the user experience.

[0040] Specifically, the dehumidifier of this embodiment further includes a float 18. The float 18 is located in the accommodation cavity 161 of the water tank 16 to detect the water level in the accommodation cavity 161 and give a full water alarm signal, facilitating the user to timely pour out the condensed water in the accommodation cavity 161 of the water tank 16 and avoiding the overflow of excessive condensed water in the accommodation cavity 161 of the water tank 16.

[0041] Furthermore, the dehumidifier of this embodiment further includes a tank cover 17. The tank cover 17 is detachably covered on the open end of the water tank 16, and the tank cover 17 can be located below the water leakage prevention device and is provided with a drain port 172 communicating with the accommodation cavity 161 of the water tank 16. Thus, the condensed water discharged from the water outlet 122 of the water receiving tray 12 flows into the accommodation groove 171 of the tank cover 17 and then is discharged into the accommodation cavity 161 of the water tank 16 through the drain port 172 of the tank cover 17. The open end of the water tank 16 is detachably covered with the tank cover 17, so as to avoid the spilling of the condensed water in the accommodation cavity 161 when the water tank 16 shakes, thereby improving the user experience.

[0042] In order to further improve the anti-leakage effect, a water outlet channel 121 is communicatively connected below the water receiving tray 12 of this embodiment. The water outlet channel 121 extends in the horizontal direction. The water outlet 122 is located at the open end of the water outlet channel 121 away from the water receiving tray 12, and a flow blocking plate 125 is convexly provided on the inner wall of the lower end of the water outlet channel 121. The flow blocking plate 125 is arranged close to the water outlet 122. The arrangement of the flow blocking plate 125 can block the accumulated water in the water receiving tray 12, preventing the accumulated water in the water receiving tray 12 from rushing towards the elastic pad 131 and causing the elastic pad 131 to be pushed open and resulting in a leakage phenomenon, thereby further making the anti-leakage effect better.

[0043] In order to reduce the drainage noise, a buffer plate 123 is provided below the water outlet channel 121 of this embodiment. The buffer end of the buffer plate 123 protrudes from the water outlet 122, and a buffer groove 124 is formed on the side of the buffer end of the buffer plate 123 close to the water outlet 122. The buffer groove 124 runs through the buffer end of the buffer plate 123. Thus, the condensed water discharged from the water outlet 122 flows into the buffer groove 124 of the buffer plate 123 and then is discharged from the buffer groove 124, thereby reducing the height of the water drop and using the height difference to reduce the sound of the water dripping, so as to reduce the drainage noise. And, a reserved groove 128 for accommodating the electromagnetic member 127 is formed at the buffer end of the buffer plate 123 of this embodiment.

[0044] In order to ensure the reliability and stability of the elastic member forcing the rotating cover 130 to rotate and reset away from the water outlet 122, the electromagnetic member 127 forms different magnetic poles when passing through currents in different directions, so that the electromagnetic member 127 attracts or repels the magnetic member 132. Thus, when the current direction of the electromagnetic member 127 causes the electromagnetic member 127 to attract the magnetic member 132, the elastic pad 131 can stably and tightly press against the water outlet 122 to seal the water outlet 122; when the current direction of the electromagnetic member 127 causes the electromagnetic member 127 to repel the magnetic member 132, synchronously under the action of the elastic member forcing the rotating cover 130 to rotate away from the water outlet 122, thus under the action of the repulsive force between the electromagnetic member 127 and the magnetic member 132 and the forcing force of the elastic member, it can be ensured that the rotating cover 130 rotates and resets away from the water outlet 122 stably and reliably.

[0045] To ensure that the elastic pad 131 is stably arranged on the rotating cover 130, in this embodiment, the rotating cover 130 is provided with an installation groove 1301 running through it. On the side of the elastic pad 131 away from the water outlet 122, an installation post 1311 protrudes. At one end of the installation post 1311 away from the elastic pad 131, a snap cap 1312 is provided. The snap cap 1312 can elastically deform and pass through the installation groove 1301 and hook on the side of the rotating cover 130 away from the water outlet 122, and the installation post 1311 is located within the installation groove 1301 to prevent the elastic pad 131 from falling off the rotating cover 130. Specifically, in this embodiment, the elastic pad 131 is a rubber pad, which has excellent elasticity and wear resistance, and can withstand a certain pressure and quickly return to its original state. Further, in this embodiment, the snap cap 1312 is provided with a plurality of through slots 13121 running through it in the axial direction of the installation post 1311. The plurality of through slots 13121 are distributed in the circumferential direction of the snap cap 1312, and each through slot 13121 runs through the outer peripheral wall of the snap cap 1312, thereby enhancing the elastic deformation ability of the snap cap 1312.

[0046] To further ensure that the elastic pad 131 is stably arranged on the rotating cover 130, in this embodiment, a stepped groove 1303 is formed on the side of the rotating cover 130 close to the water outlet 122. The elastic pad 131 is located within the stepped groove 1303, and a stepped boss 1313 adapted to the inner peripheral wall of the stepped groove 1303 protrudes from the outer peripheral wall of the elastic pad 131, avoiding the phenomenon that the preset position of the elastic pad 131 is shifted due to its own elastic deformation ability, so as to ensure that the elastic pad 131 can accurately press against the water outlet 122 to seal the water outlet 122 and prevent water leakage.

[0047] To ensure that the electromagnetic component 127 can reliably and stably adsorb the magnetic component 132 after being energized and magnetized, in this embodiment, the water receiving tray 12 is provided with a limiting surface 126. The side of the rotating cover 130 away from the water outlet 122 can abut against the limiting surface 126 to limit the rotation angle of the rotating cover 130 away from the water outlet 122, thereby avoiding the situation that the rotating cover 130 rotates too much away from the water outlet 122 and causing the electromagnetic component 127 to be unable to adsorb the magnetic component 132 after being energized and magnetized.

[0048] In this embodiment, the elastic member is a torsion spring 15. A shaft rod 14 is provided on the water receiving tray 12. The rotating cover 130 is rotatably hinged on the shaft rod 14. The spring coil of the torsion spring 15 is sleeved on the shaft rod 14, and the two torsion arms of the torsion spring 15 respectively press between the rotating cover 130 and the water receiving tray 12, thereby stably and reliably forcing the rotating cover 130 to rotate away from the water outlet 122. Specifically, in this embodiment, a hook 1302 is provided on the end face of the rotating cover 130 close to the water outlet 122. The hook 1302 can rotatably hook on the shaft rod 14 to realize the rotatable hinged arrangement of the rotating cover 130.

[0049] The above embodiments are only preferred examples of the present utility model and are not intended to limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles of the scope of the patent application of the present utility model should be included within the scope of the patent application of the present utility model.
