Description

[Technical field]

[0001] The invention relates to a drainage technology for a dehumidifier, and in particular to a detachable drainage device and a dehumidifier thereof. [Background technology]

[0002] When the dehumidifier is in use, condensed water first collects in the water tank. When the water level in the water tank reaches the set standard, the water in the water tank must be manually drained before the machine can continue to operate. This drainage processing mode is extremely inconvenient.

[0003] Therefore, dehumidifiers with automatic drainage functions continue to appear, and the condensed water is also first collected in the water tank. A drainage pump is set in the water tank. When the drainage pump is turned on, the liquid in the water tank can be extracted to a high place and discharged. However, how to disassemble and connect the water outlet connectors of the corresponding pipelines of the water tank and the drainage pump is complicated in most structures and inconvenient for installation and operation. For example, the patent publication number is CN106765544 A, and the invention name is "A dehumidifier". In the docking method, a joint assembly is sealed and set on the top of the water tank. One end of the joint assembly is pluggable and sealed on the outer wall of the first joint of the water pump. In the designed structure, there will be no cavity for storing condensed water inside the first joint. When the first joint and the joint assembly are separated, the remaining condensed water can be prevented from flowing back to the inside of the water tank through the joint assembly under the action of its own gravity. However, it is still unable to effectively solve the problem of effective plug-in fixation of the water tank and each joint, and the plug-in is often not in place or it is disconnected during use. In addition, the water pump used in existing dehumidifiers is generally a diaphragm pump. Although the diaphragm pump can pump water from a low water level to a high water level, it will be started and shut down frequently due to structural limitations, and its effective working life is therefore shortened, resulting in the automatic drainage function of the dehumidifier being lost shortly after use due to the expiration of the water pump life. Moreover, due to the influence of the use environment, the existing dehumidifier may be affected by the condensed water, dirt, and impurities, which may cause the diaphragm pump to fail to pump water normally or reduce the flow rate, which also greatly affects its life.

[0004] In short, the pipe head docking structure of the existing dehumidifier is complicated, and the operation required for converting manual drainage to automatic drainage is complicated, which brings many inconveniences to users. New technical inventions are urgently needed to solve the above problems. [Summary of the invention]

[0022] Preferably, the water pumping assembly includes a water pumping box and a water pump. The water pumping box is installed on the water receiving box in a pullable and detachable manner along the up and down vertical directions. A power interface is provided on the top of the water pumping box along the front and back lateral movement direction of the water receiving box.

[0051] In this embodiment, the detachable drainage device is disassembled and assembled in the mounting groove of the dehumidifier along the front-to-back direction. Therefore, in the specific embodiment, the detachable drainage device is not described separately, but is introduced and described in a unified manner according to the overall assembly connection relationship with the dehumidifier.

[0052] A dehumidifier, such as Figures 1 to 7 As shown, it includes an outer box body 1, and a detachable drainage device a is arranged at the lower front side of the outer box body 1. The drainage device a includes a water receiving box 2, a pumping assembly 3, a first magnetic induction switch 4, a drainage docking assembly 5 and a drainage external connection assembly 6. The water receiving box 2 is movable and inserted into the installation groove 7 of the outer box body 1 in a horizontal direction along the front and rear directions; the pumping assembly 3 is detachably installed on the water receiving box 2 in the vertical direction, and the top end is protruding relative to the inner edge of the water receiving box 2. A power interface 9 is arranged on the top along the horizontal direction of the water receiving box 2 to dock with the power plug 8 in the installation groove 7, and a drainage interface 1 is arranged on the top along the vertical direction for the drainage docking joint 51 in the installation groove 7 to be moved downward along the vertical direction to dock and insert, so as to pump out the water collected in the water receiving box 2 0; the first magnetic induction switch 4 is installed on the inner wall side of the mounting groove 7 on the outer box body 1, and is used to delay the judgment of whether the water receiving box 2 is full of water; the drainage docking assembly 5 includes a slide seat 50, a drainage docking joint 51 that moves up and down in the vertical direction, a crankshaft 52 and a knob cover 53, the drainage docking joint 51 is installed in the slide slot 500 of the slide seat 50 to slide up and down in the vertical direction, the crankshaft 52 is rotatably hinged on the slide seat 50, and is driven to rotate by the knob cover 53 installed at the outer end, and the crank 520 end of the crankshaft 52 is arranged on the inner side of the crankshaft 52. The sliding card-fitted docking is connected to the side of the drainage docking joint 51, and the circumferential rotational motion of the crankshaft 52 is converted into the up and down lifting motion of the drainage docking joint 51. After the drainage docking joint 51 moves down, it is inserted into the drainage interface 10 at the top of the pumping component 3; the drainage external connection component 6 is connected with the drainage docking joint 51 on the drainage docking component 5 through the water guiding hose 11, and is arranged on the other side of the outer box body 1 relative to the water receiving box 2. A drainage outlet joint 60 is provided on it, which is connected to a drainage pipe (not shown in the figure) for draining water outward and is used to discharge the water in the water receiving box 2 to the outside of the outer box body 1.

[0053] like Figures 7 to 12As shown, the drainage docking assembly 5 also includes a pressure cover 54 and a second magnetic induction switch 55. The second magnetic induction switch 55 is installed at the side wall of the slide slot seat 50 and is used to sense the downward movement of the drainage docking joint 51 when it is fully closed and inserted into the drainage interface 10 at the top of the pumping assembly 3; the slide slot seat 50 is provided with a shaft hole 501 for rotating and positioning the central shaft 521 of the crankshaft 52, and the slide slot seat 50 corresponding to the outer periphery of the shaft hole 501 is provided with a crank 520 that facilitates the crankshaft 52 to be inserted into the slide slot from the side to drive the drainage docking joint 51 to slide up and down along the vertical slide slot, and a shaft for limiting the crankshaft 52 to slide up and down along the vertical slide slot. The handle 520 is deflected at an angle to control the lifting and lowering distance of the drainage joint 51 through the lifting limit hole 12, and the corresponding side wall of the drainage joint 51 is provided with a transverse sliding groove 13 that cooperates with the end of the crank 520 of the crankshaft 52 in the horizontal direction relative to the up and down lifting direction; the pressure cover 54 limits and fixes the crankshaft 52 at the shaft hole 501 of the slide groove seat 50 from the side through a snap-fit ​​structure, and the outer end of the central rotating shaft 521 of the crankshaft 52 passes through the pressure cover 54 and is engaged with the knob cover 53. The knob cover 53 drives the crankshaft 52 to rotate through the central rotating shaft 521, and drives the drainage joint 51 to rise and fall through the crank 52 sliding horizontally and moving up and down in the transverse sliding groove 13 of the drainage joint 51.

[0054] Continue as Figures 7 to 12 As shown, a self-locking spring 56 is also provided at the lower part of the drainage joint 51, the bottom side of which is abutted against the bottom end surface of the slide groove of the slide groove seat 50, for automatically rising and resetting the drainage joint 51, and for the crank 520 of the crankshaft 52 to deflect through the vertical lowest limit point of the lifting limit hole 12 and then continue to deviate by a certain angle when the drainage joint 51 is lowered for docking, and is locked at the end limit position of the lifting limit hole 12 under the action of the upward reset elastic force. The corresponding lower side surface of the transverse slide groove 13 on the drainage joint 51 is recessed and provided with a self-locking point groove 130 that cooperates with the crank 520 of the crankshaft 52. The rotation limit stroke of the lifting limit hole 12 passes through the vertical highest limit point and continues to deviate by a certain angle of an arc-shaped rotation stroke distance greater than 180°. The drainage joint 51 is self-lockingly plug-in connected to the drainage interface 10 at the top of the pumping component 3 through the self-locking spring 56, and is also used to lock the plug-in connection between the water tank 2 and the outer box body 1. Moreover, the side walls of the slide seat 50 are respectively protruded with limiting columns 14 corresponding to the four corners of the pressure cover 54 for limiting and fixing, and the two sides of the slide seat 50 are also respectively protruded with U-shaped buckles 15 that are snap-fitted with the inclined protrusions on both sides of the pressure cover 54.

[0055] The self-locking structure formed by the self-locking spring 56 on the drainage docking assembly 5 forms a certain angle A between the center of the terminal position of the crankshaft 52 and the vertical direction where the rotation center is located. When in the terminal position, the self-locking spring 56 is in a state of compression amount S1. If it is to be restored, a larger compression amount and a larger reverse rotation driving force are required. When it is necessary to restore, just reversely rotate the button again. Of course, the structure here can be implemented in different ways, which can be manual, electric or other ways. In addition, after the drainage docking assembly 5 is locked downward, it will limit the water receiving box 2 from falling off the outer box body 1 in the vertical direction, and the water pump 31 of the corresponding water pumping assembly 3 on the water receiving box 2 adopts a contact solution to draw electricity, that is, the power interface 9 on the water receiving box 2 is plugged in and matched with the power plug 8 on the outer box body 1. Contact touch is inevitable during the connection process, and an arc will be generated when closing or disconnecting in the presence of electricity. Since the drainage docking assembly 5 has a self-locking structure, it can limit the water receiving box 2 from falling off. Therefore, the risk of arc caused by false connection when the power interface 9 and the power plug 8 are plugged in and matched can be effectively avoided, thereby increasing the safety of the entire machine.

[0056] like Figure 7 , Figures 12 to 17 As shown, the drainage external connection component 6 also includes a drainage joint cover 61, a magnet 62 and a third magnetic induction switch 63. The middle part of the drainage outlet joint 60 is enlarged and extended outward along the circumferential direction, and a plurality of evenly distributed embedding grooves 600 are opened along the axial direction on the outer edge for mutually locking and snapping when the drainage joint cover 61 is axially mounted on the drainage outlet joint 60. The corresponding drainage joint cover 61 is circumferentially provided with an L-shaped clamp 610 that matches each embedding groove 600; the magnet 62 is installed at the outer edge of the middle part of the drainage outlet joint 60, and a radially protruding limit block 601 is also provided on the outer edge of the middle part of the drainage outlet joint 60 beside the embedding groove 600. The drainage outlet joint 60 is inserted into the outer casing 1. The drainage hole is also provided with a positioning groove 16 that matches the drainage joint cover 61. The positioning groove 1 6 is axially recessed with an insertion groove 17 that cooperates with the limit block 601, and the corresponding bottom of the positioning groove 16 is circumferentially provided with an anti-slip groove 18 that is connected with the insertion groove 17, which is convenient for the drainage joint cover 61 to drive the limit block 601 on the drainage outlet joint 60 to be inserted from the insertion groove 17 and deflected circumferentially to prevent it from slipping and locking it at the positioning groove 16, so as to avoid water leakage or the drainage outlet joint 60 falling off when the user uses it; the magnet 62 is installed on the outer edge of the middle part of the drainage outlet joint 60, and the third magnetic induction switch 63 is installed on the outer box body 1 outside the positioning groove 16, which is used to synchronously sense the magnet 62 that is deflected into place after the limit block 601 is inserted into the anti-slip groove 18, so as to realize the alarm prompt of the drainage outlet joint 60 being inserted and anti-slip locked in place.

[0057] like Figures 3 to 5As shown, the pumping assembly 3 includes a pumping box 30 and a water pump 31. The pumping box 30 is installed on the water receiving box 2 in a pullable and detachable manner along the up and down vertical direction. A power interface 9 is provided on the top of the pumping box 30 along the front and back lateral movement direction of the water receiving box 2. A drainage interface 10 is provided on the top surface of the pumping box 30 along the up and down vertical direction. The pumping pump 31 is installed at the bottom of the pumping box 30 and is connected to the drainage interface 10 on the top surface of the pumping box 30 through a water pipe 32. A water inlet hole 33 connected to the water receiving box 2 and used for water in the water receiving box 2 to enter is provided at the water pump 31 on the side wall of the pumping box 30. A filter screen 34 that can be removed and replaced to prevent the water pump from being blocked is also installed at the water inlet hole 33 of the pumping box 30.

[0058] In this embodiment, the dehumidifier continuously drains water by using the pumping pump 31 in the pumping component 3 to discharge the condensed water in the water receiving tank 2 of the whole machine to the outside of the dehumidifier through the connecting pipeline formed by the drainage external component 6, the drainage docking component 5 and the internal water pipe.

[0059] When the water receiving box 2 is assembled on the main body of the outer box 1 of the whole machine as required, the drainage joint 51 is vertically consistent with the drainage interface 10 at the top of the pumping assembly 3. The drainage joint 51 is driven to move downward by turning the knob cover 53, that is, inserted into the drainage interface 10 at the top of the pumping assembly 3 to achieve connection. The insertion joint is designed here, which can not only realize the above-mentioned connection function, but also realize the closing of the magnetic induction switch here, giving the first control signal for the water pump 31 in the pumping assembly 3 to drain water.

[0060] At the drainage external connection component 6, the drainage outlet connector 60 is connected to the drainage docking connector 51 on the drainage docking component 5 on the back of the dehumidifier through the water guide hose 11. In order to facilitate the user to realize the drainage function of the water pump 31, the drainage outlet connector 60 is connected to the drainage pipe for outward drainage, and is used as a user accessory during specific use (that is, when manual drainage is adopted, the drainage outlet connector 60 is covered by the cover plate b). The drainage outlet connector 60 is inserted into the drainage hole of the outer box 1, and self-locking and magnetic induction switch are realized by rotation. The cooperation of the drainage external connection component 6 and the drainage docking component 5 realizes the connection between the water receiving box 2, the outer box 1 and the water guide hose 11, and realizes the continuous drainage function. In addition, magnetic induction switches are added at the drainage external connection component 6 and the drainage docking component 5, so that the machine can judge whether the water receiving box 2 is installed and whether the drainage outlet connector 60 is installed in place. The increase of induction can effectively reduce the risk of misoperation and facilitate user operation.

[0061] The above-described embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes made based on the shape, structure and principle of the present invention should be included in the protection scope of the present invention.
