Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sanitary wares, in particular to a wire-controlled drainer and a washbasin. Background Art
[0002] At present, the common drainers for washbasins on the market are pop-up drainers and flap drainers. For both of them, hands need to be put into dirty water to open the drainer cover for drainage, thus causing secondary hand dirtiness. Some existing improved drainers use a lifting drainer. The lifting drainer has a rigid structure and a lifting device needs to be installed on the side of the drainer, which requires a large space and has poor adjustability. To solve this problem, a wire-controlled drainer has been developed on the market currently. The opening and closing of the drainer cover is controlled by a table button and a wire control device, which avoids secondary hand dirtiness and the wire control device has good adjustability.
[0003] The existing wire-controlled drainers basically adopt a push rod mechanism formed by a spring and a steel wire to open and close. Since the push rod mechanism is in rigid contact with the drainer cover, when pressing the switch, the resilience of the spring, the water pressure and the gravity of the cover need to be overcome, resulting in a relatively large overall weight. And when the water flow rate continuously increases, the water pressure also increases accordingly, leading to too large pressing operation force and affecting the user experience. Content of the Utility Model
[0004] The utility model aims to solve at least one of the above technical problems in the related art to some extent. For this purpose, the utility model provides a wire-controlled drainer.
[0005] To achieve the above object, the technical solution of the utility model is as follows:
[0006] The utility model also provides a washbasin with the above wire-controlled drainer.
[0007] The wire-controlled drainer according to the first aspect embodiment of the utility model includes a drain cover, a connecting rod, a driving component, a drain elbow and a lever component. The lever component is rotatably installed in the drain elbow through a rotating shaft. The lever component has a force application end and a resistance end. The upper end of the connecting rod is connected to the drain cover, and the lower end extends into the drain elbow and abuts against the resistance end. A transmission wire installation opening is formed on the drain elbow. The driving component includes a pressing mechanism and a transmission wire. One end of the transmission wire is connected to the pressing mechanism, and the other end extends into the drain elbow through the transmission wire installation opening and abuts against the force application end. Taking the distance from the contact point between the transmission wire and the force application end to the rotating shaft as L1, and taking the distance from the contact point between the connecting rod and the resistance end to the rotating shaft as L2, L1 > L2. Pressing the pressing mechanism can drive the transmission wire to press the force application end, thereby lifting the connecting rod to open the drain cover.
[0008] The wire-controlled water remover according to the embodiment of the utility model has at least the following beneficial effects:
[0009] The utility model reduces the switching operation force of the wire-controlled water drainer through the unique lever component design. When the wire-controlled water drainer is draining normally, the pressing mechanism is pressed to transmit the pressing force and displacement to the force-applying end of the lever component through the transmission line. According to the balance of the two forces of the lever, the resistance end of the lever component will generate an upward thrust to lift the connecting rod and then lift the drain cover, thereby realizing downward drainage. Since the force arm L1>L2, the drain cover can be lifted with a smaller pressing force, which saves effort and improves the user experience.
[0010] According to some embodiments of the utility model, an overflow pipe is also included, and the sewer bend pipe has a vertical pipe section, a horizontal pipe section and an oblique pipe section that are connected to each other.

When the lever component is in the initial position, the side wall of the lever component is opposite to the limiting side wall. The limiting side wall can prevent the short cylinder of the lever component from escaping from the first U-shaped through groove when the lever component is working.

Detailed Description of the Specific Embodiment
[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "vertical", "horizontal", "oblique", "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present utility model.
[0033] Refer to Figures 1 - 3, A wire-controlled water drainer, comprising a water drain cover 100, a connecting rod 200, a driving assembly, a downward water pipe 400 and a lever member 500. The lever member 500 is rotatably mounted in the downward water pipe 400 through a rotating shaft. The lever member 500 has a force application end 510 and a resistance end 520. The upper end of the connecting rod 200 is connected to the water drain cover 100, and the lower end extends into the downward water pipe 400 and abuts against the resistance end 520. A transmission wire installation opening 410 is formed on the downward water pipe 400. The driving assembly includes a pressing mechanism 300 and a transmission wire. One end of the transmission wire is connected to the pressing mechanism 300, and the other end extends into the downward water pipe 400 through the transmission wire installation opening 410 and abuts against the force application end 510. Taking the distance from the abutting point of the transmission wire and the force application end 510 to the rotating shaft as L1, and taking the distance from the abutting point of the connecting rod 200 and the resistance end 520 to the rotating shaft as L2, L1 > L2. Pressing the pressing mechanism 300 can drive the transmission wire to press down the force application end 510, thereby lifting the connecting rod 200 to open the water drain cover 100.
[0034] The present utility model reduces the switching operation force of the wire-controlled water drainer through the unique design of the lever member 500. When the wire-controlled water drainer is draining water normally, pressing the pressing mechanism 300 transmits the pressing force and displacement to the force application end 510 of the lever member 500 through the transmission wire. According to the two-force balance of the lever, an upward thrust will be generated at the resistance end 520 of the lever member 500, pushing up the connecting rod 200, and then pushing up the water drain cover 100, thereby realizing downward drainage; since the force arm L1 > L2, for example, the force arm L1:L2 is designed to be 1.5:1. According to the two-force balance theorem, the force required for the resistance end 520 of the lever member 500 to push up the water drain cover 100 is equal to the force of the transmission wire pressing the force application end 510 of the lever member 500 multiplied by 1.5. That is, through the lever member 500, the water drain cover 100 can be pushed up with a smaller pressing force, achieving the effect of saving effort.
[0035] In some embodiments of the present utility model, an overflow pipe 700 is further included. The downward water pipe 400 has a vertically connected pipe section 420, a horizontally connected pipe section 430 and an obliquely connected pipe section 440. The lower end of the connecting rod 200 extends into the vertically connected pipe section 420. The obliquely connected pipe section 440 is located above the horizontally connected pipe section 430. One end of the obliquely connected pipe section 440 is joined at the intersection of the vertically connected pipe section 420 and the horizontally connected pipe section 430, and the other end is connected to the overflow pipe 700. The transmission wire installation opening 410 is formed on the obliquely connected pipe section 440 and is located above the force application end 510. The force application end 510 is a disk structure with its disk facing upward.
[0036] According to the overflow performance requirements in 5.7.3 of JC-T 932, the overflow speed of the drainer matched with the washbasin 800 should be not less than 0.25 L / S. At present, most drainers for the washbasin 800 are provided with overflow channels on the washbasin 800. Due to the processing difficulty and space limitation, it is very difficult for the overflow volume to exceed 0.25 L / S. When the faucet is forgotten to be turned off, the water on the washbasin 800 will overflow onto the tabletop in a short time, causing adverse effects such as water accumulation in the bathroom. In addition, according to the requirements for the drain outlet size of the washbasin in Appendix B.5 of GB 6952, when there is an overflow water channel, the thickness of the drain outlet of the washbasin 800 is 51 ± 6 mm, and when there is no overflow water channel, the drain outlet thickness is 25 + 50 mm. Therefore, when the requirement of the drainer is reverse overflow, the corresponding washbasin 800 inevitably needs to increase the thickness. At the same time, since the drainer needs to be provided with an overflow hole 810, the length of the body is increased. Coupled with the fact that the ejector rod mechanism of the wire-controlled drainer is usually arranged below the drainer; the combination of the three results in an excessive occupied space after the wire-controlled drainer is installed, greatly reducing the storage space of the bathroom cabinet.
[0037] The utility model adopts an external overflow pipe 700, the upper and lower ends of which are respectively connected to the washbasin 800 and the downcomer 400. When the water volume in the washbasin 800 exceeds the overflow hole 810 of the washbasin 800, the water flow will flow into the overflow pipe 700 through the overflow hole 810. Due to the height difference between the overflow hole 810 of the washbasin 800 and the inlet of the inclined pipe section 440 of the downcomer 400, the water flow in the overflow pipe 700 will generate a water pressure on the disc surface of the lever component 500 installed at the downcomer 400. When the above water pressure is greater than the sum of the water pressure on the drain cover 100 at the resistance end 520 of the lever component 500 and the gravity of the drain cover 100 and the connecting rod 200, the drain cover 100 will be rotated and lifted by the lever component 500, so that the drain port under the washbasin 800 will assist in draining water, achieving the effect of accelerating overflow. Based on the above structure, an appropriate flow area can be designed to meet the specified overflow standard; at the same time, it is designed that the water pressure received by the force application end 510 of the lever component 500 during the drainage of the overflow pipe 700 is greater than the sum of the water pressure on the drain cover 100 received by the resistance end 520 of the lever component 500 and the gravity of the drain cover 100 and the connecting rod 200, so that the drain cover 100 can be opened, forming the effect of simultaneous drainage of the overflow hole 810 and the drain port, greatly accelerating the overflow speed and preventing the water from overflowing the tabletop when the faucet is forgotten to be turned off. The disc surface design can greatly strengthen the pressure of the water flow on the force application end 510 of the lever component 500 during overflow drainage, so that the drain cover 100 can be opened through the lever component 500 during overflow to achieve the effect of double drain port drainage. In addition, through the overflow structure of the utility model, the overflow hole 810 on the side of the drainer and the overflow channel of the washbasin 800 can be cancelled, shortening the length of the drainer body and the thickness of the drain port of the washbasin 800. At the same time, the overall wire control structure and the overflow structure are both designed above the downcomer 400, which will not affect the space of the bathroom cabinet below, thus greatly reducing the occupied space of the drainer and increasing the storage space of the bathroom cabinet.
[0038] In some embodiments of the present utility model, with reference to Figures 4 - 6, a first positioning frame 450 and a second positioning frame 460 are provided left and right inside the downcomer 400. The first positioning frame 450 has a first U-shaped through groove, and the second positioning frame 460 has a second U-shaped through groove. The notch directions of the first U-shaped through groove and the second U-shaped through groove are offset in the left-right direction. Short cylinders 530 and long cylinders 540 are respectively provided on the left and right sides of the lever member 500. The long cylinder 540 and the short cylinder 530 are coaxially arranged. The long cylinder 540 is in mating contact with the arc-shaped bottom of the second U-shaped through groove, and the short cylinder 530 is in mating contact with the arc-shaped bottom of the first U-shaped through groove. A displacement space is left between the first positioning frame 450 and the second positioning frame 460 for the lever member 500 to move from right to left so that the short cylinder 530 can be inserted into the first U-shaped through groove. The long cylinder 540 and the short cylinder 530 are located between the force application end 510 and the resistance end 520. The installation method of the downcomer 400 and the lever member 500 is as follows: Place the disk surface of the lever member 500 facing upwards, place the resistance end 520 into the installation from the inlet of the inclined pipe section 440, align the long cylinder 540 with the notch of the second U-shaped through groove and extend it until the long cylinder 540 contacts the arc-shaped bottom of the second U-shaped through groove, and then translate the lever member 500 to the left so that the short cylinder 530 is inserted into the arc-shaped bottom of the first U-shaped through groove, thus completing the installation of the lever member 500. The lever member 500 rotates with the short cylinder 530 and the long cylinder 540 as the rotation axes.
[0039] In some embodiments of the present invention, a limiting side wall 461 protrudes from the left side of the second positioning frame 460. When the lever member 500 is in the initial position, the side wall of the lever member 500 faces the limiting side wall 461. The limiting side wall 461 can prevent the short cylinder 530 from disengaging from the first U-shaped through groove when the lever member 500 is working. The initial position is the angular position of the lever member 500 when the drain cover 100 is completely closed. After the drainer is installed, the lever member 500 will be in the initial position. Since the limiting side wall 461 restricts the left and right displacement of the lever member 500 in the initial position, the lever member 500 can rotate and swing after installation without falling off. The present invention realizes the convenient disassembly and fixation of the lever member 500 by arranging two positioning frame structures with U-shaped through grooves inside the downcomer 400 to fix the lever member 500 in a staggered manner.
[0040] In some embodiments of the present invention, the part of the resistance end 520 in contact with the connecting rod 200 is arc-shaped. The resistance end 520 is convex and round, reducing the contact friction between the connecting rod 200 and the resistance end 520, improving the movement smoothness of the connecting rod 200, and making the operation smoother and more labor-saving.
[0041] In some embodiments of the present utility model, the transmission line is a spring wire 600. The existing wire-controlled water drainer uses a steel wire as the transmission medium, which is too heavy, and a larger spring 340 resilience needs to be designed, resulting in an excessive switch operating force. The present utility model uses a lighter spring wire 600 to replace the steel wire rope to reduce the force of the spring 340, and further reduce the switch operating force. A plastic sleeve is sleeved outside the spring wire 600. By adjusting the pitch of the spring 340, the transmission displacement loss of the spring wire 600 can be reduced. Thimbles are welded at both ends of the spring wire 600, and the thimbles are abutted against the corresponding components. The pressing force and displacement are transmitted from the thimble at one end to the thimble at the other end through the spring wire 600, realizing the transmission of force and displacement. Since the pressing force of the button 380 is equal to the resilience of the spring 340 and the pressure of the thimble pressing down the lever component 500, and the resilience of the spring 340 is equal to the gravity of parts such as the spring wire 600, the thimble and the button 380. Since the spring wire 600 is lighter than the ordinary steel wire, the resilience required for the spring 340 to rebound is smaller, thereby reducing the switch operating force of the button 380, achieving the effect of saving effort. At the same time, the spring wire 600 has good flexibility and is convenient for installation.
[0042] In some embodiments of the present utility model, with reference to Figures 7 - 9The pressing mechanism 300 includes a movable rod 310, a rotating claw 320, a limiting sleeve 330 and a spring 340. The rotating claw 320 is rotatably sleeved on the movable rod 310. The movable rod 310 can drive the rotating claw 320 to move up and down. The outer circumferential spacing of the rotating claw 320 is provided with a protrusion 321, and the upper surface and the lower surface of the protrusion 321 are both inclined surfaces. The movable rod 310 is inserted into the limiting sleeve 330. The inner wall of the limiting sleeve 330 is provided with ribs 331 along the circumferential spacing. The ribs 331 are arranged along the axial direction of the limiting sleeve 330. A sliding groove 332 is formed between adjacent ribs 331. The protrusion 321 can be slidably embedded in the sliding groove 332. The ribs 331 The bottom of the limit sleeve 330 has a limit notch 333, and the limit sleeve 330 is provided with a serrated surface 334 along the circumferential direction. The serrated surface 334 has a plurality of guide slopes. The serrated surface 334 is located below the rib 331 and leaves a space between the rib 331 and the rib for the rotation claw 320 to move. The rotation claw 320 moves downward to abut against the guide slope and rotates. When the rotation claw 320 rotates to the first position, it moves upward to engage with the limit notch 333. When the rotation claw 320 rotates to the second position, it moves upward to be embedded in the slide groove 332. The spring 340 is located below the movable rod 310. The movable rod 310 moves downward to compress the spring 340. The movable rod 310 is connected to the transmission line. Further, the upper end of the movable rod 310 is connected to a button 380 through a connecting rod 390. The working principle of the pressing mechanism 300 is as follows: by pressing the button 380, the movable rod 310 moves up and down, driving the rotating claw 320 to move up and down. The rotating claw 320 moves downward so that its lower surface contacts the guiding inclined surface on the sawtooth surface 334 and rotates, so that the rotating claw 320 is staggered with the slide groove 332 and faces the limiting notch 333. The rotating claw 320 moves upward so that its upper surface is fixedly engaged with the limiting notch 333 through the rebound of the spring 340. The displacement at this time is the distance that the ejector pin on the spring line 600 moves downward. Similarly, by pressing the button 380 once more, the rotating claw 320 moves downward so that its lower surface contacts the guiding inclined surface on the sawtooth surface 334 again and rotates, so that the rotating claw 320 is staggered with the limiting notch 333 and faces the slide groove 332. The rotating claw 320 moves upward so that its upper surface is reengaged with the slide groove 332 through the rebound of the spring 340, and returns to its original position. By means of the pressing mechanism 300 , the button 380 can be pressed to open and close the drain cover 100 . Furthermore, the bottom of the rib 331 has an inclined surface for guiding the rotating claw 320 into the sliding groove 332 .
[0043] In some embodiments of the present invention, the pressing mechanism 300 further includes a fixing sleeve 350 . The fixing sleeve 350 is located below the limiting sleeve 330 and is fixedly connected to the limiting sleeve 330 . The spring 340 is disposed in the fixing sleeve 350 .
[0044] In some embodiments of the present utility model, the pressing mechanism 300 further includes a locking nut 360 and a decorative cover 370. The outer wall of the limiting sleeve 330 is provided with threads. The decorative cover 370 and the locking nut 360 are sleeved outside the limiting sleeve 330 and are threadedly connected to the limiting sleeve 330. The decorative cover 370 is located above the locking nut 360. During installation, the decorative cover 370, the connecting rod 390, and the button 380 are located on the countertop of the washbasin 800 for the user to press. The locking nut 360 is located below the countertop of the washbasin 800 to lock the entire pressing mechanism 300 on the washbasin 800. During installation, first install the limiting sleeve 330, the movable rod 310, the rotating claw 320, the connecting rod 390, the decorative cover 370, and the button 380 in sequence, and then install this assembly on the opening of the countertop of the washbasin 800.
