Description

Technical Field

[0001] The present invention relates to the technical field of condensation clothes dryers, and particularly to a waterproof structure for a condensation clothes dryer. Background Art

[0002] A condensation clothes dryer is a commonly used household appliance that can dry clothes. Air is heated into dry hot air after passing through a heater. The dry hot air passes through the clothes and becomes cold and humid air. The cold and humid air passes through a condensation system and becomes dry cold air. At the same time, the separated water is collected in a water storage box or directly discharged through a drain pipe. The air enters the drum after heating and repeats the next cycle to achieve the clothes drying function.

[0003] The patent publication number of an existing patent application is: CN215714119U, and the publication date is February 1, 2022. The name of this patent is "A water storage box and a clothes dryer". The water storage box includes a box body. An inlet is provided at the upper part of the box body. The inside of the box body is hollow to form a water storage cavity. The inlet is communicated with the water storage cavity. A water retaining ring extending into the water storage cavity is provided at the inlet. The water retaining structure of the water storage box of the present application can divert and buffer the condensed water to prevent it from splashing out of the box body. The water retaining effect is good. The provided drain opening keeps the atmospheric pressure inside and outside the box body balanced, making the water inlet and drainage smoother and the box body can be emptied completely. The structure is simple and convenient for production and processing.

[0004] The above application has deficiencies. Although a water retaining ring is installed at the inlet, it cannot completely prevent the condensed water from splashing when it falls. In order to prevent the condensed water from flowing randomly after splashing and causing the internal components of the clothes dryer to get wet, a water collecting groove is generally opened at the inlet to collect the splashed water. However, after the water storage box is full of water, during the process of taking it out and after taking it out, the condensed water sloshes back and forth and is easily spilled from the water collecting groove, which will affect the cleaning speed of the water storage box. Summary of the Invention

[0005] The purpose of the present invention is to provide a waterproof structure for a condensation clothes dryer to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A waterproof structure for a condensation dryer, comprising a water storage box and a water inlet opened on the top surface of the water storage box, further comprising a water retaining ring nested in the water inlet. An annular water collecting groove is opened on the top surface of the water storage box around the water inlet, and the annular water collecting groove is communicated with the inside of the water storage box. An opening and closing water scraping mechanism is elastically connected with the water retaining ring. One side of the opening and closing water scraping mechanism abuts against the annular water collecting groove, and the other side obliquely abuts against the side wall of the water retaining ring. A floating disk is located inside the water storage box, and a splash-proof net is installed at the center of the floating disk. A limiting connecting piece connected to the inner wall of the water retaining ring is installed on the top surface. When the water retaining ring descends, it drives the opening and closing water scraping mechanism to scrape the water in the annular water collecting groove into the water storage box, then seals the communication part between the two, and locks the water retaining ring by the limiting connecting piece.

[0008] Preferably, a limiting ring is installed inside the water storage box at the bottom of the water retaining ring, and the outer diameter of the limiting ring is larger than the diameter of the water inlet.

[0009] Preferably, the splash-proof net is located below the water inlet, and multiple layers are arranged up and down on the splash-proof net.

[0010] Preferably, the opening and closing water scraping mechanism includes a sleeve ring movably sleeved outside the water retaining ring. A plurality of scraping strips are annularly distributed on the outer side of the sleeve ring. Water inlet holes matching the scraping strips are opened at the bottom of the annular water collecting groove.

[0011] Preferably, a top spring is installed between the sleeve ring and the water retaining ring. A wedge-shaped pressing block is fixedly connected to the outer wall of the water retaining ring. A wedge-shaped abutting block abuting against the wedge-shaped pressing block is installed on the top of the sleeve ring. When the water retaining ring descends vertically, it forces the sleeve ring to rotate.

[0012] Preferably, the limiting connecting piece includes connecting rods symmetrically fixed on the top of the floating disk. A limiting groove is vertically opened on one side of the connecting rod. Elastic teeth inserted into the limiting groove are elastically embedded in the inner wall of the water retaining ring. A plurality of limiting teeth are installed on the inner wall of the limiting groove.

[0013] Preferably, a counterweight disk is movably installed at the bottom of the floating disk, and the bottom surface of the counterweight disk abuts against the inner wall of the water storage box.

[0014] Preferably, a plurality of water guiding top rods are annularly inserted on the top surface of the floating disk. Each water guiding top rod is respectively located below each water inlet hole, and the water guiding top rod abuts against the scraping strip in a matching manner.

[0015] Preferably, the water guiding top rod movably penetrates through the floating disk, and a lapping rod is horizontally fixedly connected to the bottom end of the water guiding top rod. One end of the lapping rod contacts the top of the counterweight disk.

[0016] Preferably, a butt joint piece is elastically inserted at one end of the scraping strip. A rack matching the butt joint piece is vertically installed on the inner side wall of the annular water collecting groove.

[0017] In the above technical solution, by setting a water baffle ring and a splash-proof net below it, the amount of splashed condensate is reduced. At the same time, the peripheral annular water collecting tank can also collect the accidentally splashed condensate, preventing the splashed water from flowing randomly, expanding the scope of condensate collection. And when the water storage box is pulled out from the dryer, the water baffle ring is pressed down, which will squeeze and force the opening and closing water scraping mechanism to scrape the water in the annular water collecting tank to the connection point, allowing the water splashed into the annular water collecting tank to flow into the water storage box. At the same time, the opening and closing water scraping mechanism seals the connection between the annular water collecting tank and the water storage box. At this time, the height of the water baffle ring is also locked by the limit connecting piece. Thus, when the water storage box is completely taken out, the inside of the annular water collecting tank and the water storage box are separated from each other, preventing the condensate from splashing out from the connection between the annular water collecting tank and the water storage box with a lower height due to back-and-forth shaking after being taken out, avoiding accidental spillage of the condensate, and making it more convenient to empty the water storage box.

[0018] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are not intended to limit the present disclosure.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-8 , a waterproof structure for a condensation dryer provided by an embodiment of the present invention includes a water storage box 1 and a water inlet 101 opened on the top surface of the water storage box 1, and further includes a water retaining ring 2 nested in the water inlet 101. An annular water collecting groove 102 is opened on the top surface of the water storage box 1 around the water inlet 101, and the annular water collecting groove 102 is communicated with the inside of the water storage box 1. An opening and closing wiper mechanism 3 is elastically connected to the water retaining ring 2. One side of the opening and closing wiper mechanism 3 abuts against the annular water collecting groove 102, and the other side abuts against the side wall of the water retaining ring 2 obliquely. A floating disk 4 is located inside the water storage box 1, and a splash-proof net 5 is installed at the center of the floating disk 4. A limit connecting piece 6 connected to the inner wall of the water retaining ring 2 is installed on the top surface. When the water retaining ring 2 descends, it drives the opening and closing wiper mechanism 3 to scrape the water in the annular water collecting groove 102 into the water storage box 1, then seals the connection between the two, and locks the water retaining ring 2 by the limit connecting piece 6.

[0033] Specifically, the condensing dryer is provided with a receiving groove for the complete insertion of the water storage box 1. After the water storage box 1 is inserted into the condensing dryer, it is used to receive the condensed water in the water storage tank of the dryer. After the dryer is started, the air is heated by the heater into dry hot air inside the dryer. The dry hot air passes through the clothes and becomes cold and wet air. The cold and wet air then passes through the condenser and becomes dry cold air. At the same time, the water separated out by the condenser is collected and drips into the water storage tank of the dryer. The water storage tank is used to receive the condensed water dripping from the condenser. Then, the condensed water in the water storage tank of the dryer is pumped into the water storage box 1 by a water pump. The water delivery pipeline on the water pump is not fixed to the water inlet 101 of the water storage box 1, which facilitates the user to pull out the water storage box 1 to regularly clean the separated water. The water blocking ring 2 is vertically slidably inserted into the water inlet 101 of the water storage box 1. It is pushed up under the action of elastic force, which can increase the height of the water inlet 101 and can also be forced to descend and retract into the water inlet 101. However, the water blocking ring 2 cannot rotate during its lifting and lowering process. After the condensed water drips into the water storage box 1 along the water inlet 101, the water blocking ring 2 cooperates with the splash-proof net 5 that always floats on the liquid surface to prevent the condensed water from splashing out easily. At the same time, an annular water collecting groove 102 is additionally provided on the water storage box 1. Even if the condensed water splashes out, it will fall into the annular water collecting groove 102, thereby preventing the splashed condensed water from flowing randomly and avoiding the corrosion of the internal parts of the dryer by the condensed water. The annular water collecting groove 102 is also connected to the internal water storage space of the water storage box 1. When the water in the annular water collecting groove 102 is too much, it will flow back into the water storage box 1 through the connection, preventing the water in the annular water collecting groove 102 from overflowing. When it is necessary to clean the condensed water in the water storage box 1, the water storage box 1 inserted into the dryer is pulled out. During the pulling out process, as the position of the water blocking ring 2 changes, the receiving groove in the dryer forces the water blocking ring 2 to move downward into the water storage box 1. When the water blocking ring 2 moves downward, it will squeeze and drive the opening and closing water scraping mechanism 3 to rotate in the annular water collecting groove 102, making the opening and closing water scraping mechanism 3 turn towards the connection between the annular water collecting groove 102 and the water storage box 1. During the rotation process, the water remaining on the inner wall of the annular water collecting groove 102 is concentrated and scraped to this connection, for the secondary collection of the condensed water in the annular water collecting groove 102. And the opening and closing water scraping mechanism 3 will continue to rotate until it covers the connection. At the same time, the water blocking ring 2 no longer descends and is restricted and reset by the limit connecting piece 6, so that when the user pulls out the water storage box 1, there is not a large amount of condensed water remaining in the annular water collecting groove 102, and the connection between the annular water collecting groove 102 and the water storage box 1 is in a closed state, which can effectively prevent the condensed water in the box from splashing out and spilling from this relatively low connection due to the shaking of the water storage box 1.

[0034] Compared with the prior art, in the embodiment of the present invention, by providing a water baffle 2 and a splash-proof net 5 below it, the amount of splashed condensate is reduced. At the same time, the peripheral annular water collecting tank 102 can also collect the accidentally splashed condensate, preventing the splashed water from flowing randomly and expanding the range of condensate collection. And when the water storage box 1 is pulled out from the dryer, the water baffle 2 is pressed down, which will squeeze and force the opening and closing water scraping mechanism 3 to scrape the water in the annular water collecting tank 102 to the communication part, allowing the water splashed into the annular water collecting tank 102 to flow into the water storage box 1. At the same time, the opening and closing water scraping mechanism 3 seals the communication part between the annular water collecting tank 102 and the water storage box 1. At this time, the height of the water baffle 2 is also locked by the limit connecting piece 6. Thus, when the water storage box 1 is completely taken out, the inside of the annular water collecting tank 102 and the water storage box 1 are separated from each other, preventing the condensate from splashing out from the communication part between the annular water collecting tank 102 and the water storage box 1 with a lower height due to back-and-forth shaking after being taken out, avoiding accidental spilling of the condensate, and making it more convenient to empty the water storage box 1.

[0035] In a further embodiment of the present invention, a limit ring 201 is installed inside the water storage box 1 at the bottom of the water baffle 2. The outer diameter of the limit ring 201 is larger than the diameter of the water inlet 101. A retaining ring 204 is fixed at the top of the water baffle 2. The inner diameter of the retaining ring 204 is smaller than the inner diameter of the water baffle 2. And a drip slope is provided on both the inner and outer edges of the retaining ring 204. Specifically, the limit ring 201 is located inside the water storage box 1, which can prevent the water baffle 2 from detaching from the water inlet 101 and avoid the separation of the water baffle 2 and the water storage box 1 caused by the vibration generated during the operation of the dryer. The inner ring of the retaining ring 204 is smaller than the inner diameter of the water baffle 2, which can further prevent the dripping condensate from splashing out from the periphery of the water baffle 2, playing a role in stable splash prevention.

[0036] In a further embodiment of the present invention, the splash-proof net 5 is located below the water inlet 101, and multiple layers of the splash-proof net 5 are arranged up and down. Specifically, the multiple layers of the splash-proof net 5 catch the dripping condensate directly below the water inlet 101, allowing the condensate to disperse in the mesh holes of the splash-proof net 5, reducing the splashing amplitude. At the same time, the splash-proof net 5 is arranged in the floating tray 4, enabling the splash-proof net 5 to always fit on the liquid surface inside the water storage box 1 to achieve a continuous buffering effect.

[0037] In a further embodiment of the present invention, the opening and closing wiper mechanism 3 includes a collar 301 movably sleeved outside the water retaining ring 2. A plurality of wiper strips 302 are annularly distributed on the outer side of the collar 301. Water inlet holes 103 matching the wiper strips 302 are formed at the bottom of the annular water collecting tank 102. Specifically, when the water retaining ring 2 does not descend, the positions of the wiper strips 302 outside the collar 301 and the positions of the water inlet holes 103 are staggered from each other, and a space is reserved between the wiper strips 302 and the corresponding water inlet holes 103. The wiper strips 302 can also play a role in blocking water, dividing the water in the annular water collecting tank 102 into various areas, so as to ensure that the water splashed into the annular water collecting tank 102 can quickly flow back into the water storage box 1 along the respective water inlet holes 103 at the same time, preventing the condensate water in the annular water collecting tank 102 from staying for too long.

[0038] In a further embodiment of the present invention, a top spring 7 is installed between the collar 301 and the water retaining ring 2. The bottom end of the top spring 7 is fixed to the top of the collar 301, and the top end is fixed to the retaining ring 204 at the top of the water retaining ring 2. A wedge-shaped pressing block 202 is fixedly connected to the outer wall of the water retaining ring 2. A wedge-shaped abutting block 303 that abuts against the wedge-shaped pressing block 202 is installed at the top of the collar 301. When the water retaining ring 2 descends vertically, it forces the collar 301 to rotate. Specifically, after the entire water storage box 1 is completely inserted into the dryer, the top spring 7 can push up the water retaining ring 2. At this time, the wedge-shaped pressing block 202 on the side wall of the water retaining ring 2 does not exert a force on the wedge-shaped abutting block 303 on the collar 301. When the collar 301 is not pressed by other external forces, the top spring 7 will exert a torsion force on it, keeping it at a fixed angle all the time, so that the wiper strips 302 on the collar 301 and the water inlet holes 103 are staggered from each other. Thus, after the water storage box 1 is inserted into the dryer, the annular water collecting tank 102 and the water storage box 1 are in a continuously connected state, facilitating the collection of the injected condensate water and the splashed condensate water. When the water storage box 1 is pulled out, the receiving groove on the dryer will press against the water retaining ring 2, forcing it to gradually descend. By the wedge-shaped pressing block 202 outside the water retaining ring 2 squeezing the wedge-shaped abutting block 303, the collar 301 is forced to rotate passively, so that the wiper strips 302 rotate towards the direction of the water inlet holes 103 and finally turn above the water inlet holes 103 to block them. When the collar 301 drives the wiper strips 302 to rotate, the wiper strips 302 can scrape the residual water droplets in different areas of the annular water collecting tank 102 into the water inlet holes 103. The wiper strips 302 not only clean the residual coolant but also block the water inlet holes 103, effectively avoiding the splashing of the coolant in the water storage box 1.

[0039] In a further embodiment of the present invention, the limiting connecting member 6 includes a connecting rod 601 symmetrically fixed to the top of the floating disc 4. A limiting groove 602 is vertically formed on one side of the connecting rod 601. Elastic teeth 203 inserted into the limiting groove 602 are elastically embedded in the inner wall of the water retaining ring 2. A plurality of limiting teeth 603 are installed on the inner wall of the limiting groove 602, and the limiting teeth 603 are located below the elastic teeth 203. Specifically, a pair of elastic teeth 203 on the inner wall of the water retaining ring 2 are inserted into the limiting grooves 602 of the two connecting rods 601 on both sides under the action of elastic force, so that the floating disc 4 and the water retaining ring 2 are movably connected together, enabling the floating disc 4 to rise as the liquid level in the water storage box 1 rises. When the floating disc 4 rises to a corresponding threshold, during the downward movement of the water retaining ring 2, its elastic teeth 203 will continuously abut against the respective limiting teeth 603 until the water retaining ring 2 drives the scraping strips 302 on the collar 301 to block the water inlet holes 103. Through the clamping cooperation between the limiting teeth 603 and the elastic teeth 203, even if the water storage box 1 is completely pulled out of the dryer, the water retaining ring 2 will not reset only under the action of the top spring 7. If the amount of water in the water storage box 1 is not sufficient to allow the floating disc 4 to rise to a certain height, even if the water retaining ring 2 itself descends, it is impossible to establish a clamping cooperation relationship between the elastic teeth 203 and the limiting teeth 603, facilitating the reset of the water retaining ring 2 after the water in the water storage box 1 is processed.

[0040] In a further embodiment of the present invention, a sleeve 403 is fixedly connected to the bottom of the floating disc 4. A counterweight disc 8 is movably installed in the sleeve 403, and the bottom surface of the counterweight disc 8 rests on the inner wall of the water storage box 1. A counterweight ring is embedded in the top of the floating disc 4. Specifically, the counterweight disc 8 contacts the bottom surface of the inner wall of the water storage box 1 by virtue of its own weight, which can increase the weight at the annular water collecting groove 102, reduce the shaking amplitude of the water storage box 1 during the operation of the dryer, and it will not affect the up and down movement of the floating disc 4 with the liquid level. When the floating disc 4 rises, the distance between the counterweight disc 8 and the floating disc 4 will also increase. When the user takes out the water storage box 1 and turns it over to pour out the condensed water inside, the counterweight disc 8 will impact and continuously press on the floating disc 4. When the limiting ring 201 on the water retaining ring 2 fits the water inlet 101 again, the collar 301 will reset and rotate under the torsional force of the top spring 7, moving the scraping strip 302 away from the water inlet hole 103, thereby increasing the drainage channel for the condensed water and accelerating the drainage efficiency. At the same time, when the floating disc 4 moves downward towards the water retaining ring 2, the respective limiting teeth 603 will continuously abut and impact the elastic teeth 203, causing the water retaining ring 2 to vibrate continuously, shaking off the remaining condensed water in the water storage box 1 and cleaning more thoroughly.

[0041] In a further embodiment of the present invention, a number of water guiding top rods 401 are inserted annularly on the top surface of the floating disk 4. Each water guiding top rod 401 is respectively located below each water inlet hole 103. One side of the scraping strip 302 is fixedly connected with a retaining piece 304. The retaining piece 304 and the water guiding top rod 401 are in abutting cooperation. Specifically, the water guiding top rod 401 is located below the water inlet hole 103. When the water storage box 1 is turned over to pour out the condensed water, the opening and closing water scraping mechanism 3 rotates and resets first. Then, the floating disk 4 will drive each water guiding top rod 401 to pass through the water inlet hole 103, allowing the condensed water to drain outwards along the water guiding top rod 401, playing a role in hydrophobicity. And when the condensed water flows out along the water guiding top rod 401, it will not adhere to the water inlet hole 103. Since after the scraping strip 302 in the opening and closing water scraping mechanism 3 is reset, its retaining piece 304 will move above the water inlet hole 103. After the water guiding top rod 401 moves downward out of the water inlet hole 103, it will squeeze the retaining piece 304, separating the scraping strip 302 from the bottom of the annular water collecting groove 102, facilitating the user to wash it and preventing debris residue from affecting the water scraping effect.

[0042] In a further embodiment of the present invention, the water guiding top rod 401 movably penetrates through the floating disk 4, and a lapping rod 402 is horizontally and fixedly connected to the bottom end of the water guiding top rod 401. One end of the lapping rod 402 contacts the top of the counterweight disk 8. Specifically, the water guiding top rod 401 is movably inserted on the floating disk 4, which can prevent the water guiding top rod 401 from rising together with the floating disk 4, prevent the water guiding top rod 401 from being prematurely ejected from the water inlet hole 103 when there is too much condensed water in the water storage box 1, and avoid the water guiding top rod 401 blocking the rotation of the scraping strip 302 to block the water inlet hole 103. At the same time, after the water storage box 1 is turned over, it will also squeeze the lapping rod 402 through the counterweight disk 8 to move the rod head part of each water guiding top rod 401 downward out of the water inlet hole 103, accelerating the discharge of the condensed water.

[0043] In a further embodiment of the present invention, a contact member 9 is elastically inserted at one end of the scraping strip 302, and a rack 104 matched with the contact member 9 is vertically installed on the inner side wall of the annular water collecting groove 102. Specifically, when the water guiding top rod 401 presses downward on the scraping strip 302, it forces the scraping strip 302 to descend. Since after the collar 301 rotates and resets, the wedge-shaped abutting block 303 on the collar 301 and the wedge-shaped pressing block 202 outside the water blocking ring 2 do not abut against each other, when the scraping strip 302 moves in the opposite direction of the water inlet 101, the collar 301 will not rotate, allowing the contact member 9 on the scraping strip 302 to continuously press against the rack 104, so that the scraping strip 302 separated from the bottom of the annular water collecting groove 102 generates a large amplitude of vibration, thereby shaking off impurities such as residual condensed water and dust on each scraping strip 302.

[0044] Only certain exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
