Description

Technical Field

[0001] The invention relates to the technical field of wash basins, and more particularly to a water-saving multifunctional wash basin. Background Art

[0002] There is a washbasin installed in every household's bathroom. A washbasin and faucet are installed in the central part of the washbasin, which are used for washing in daily life. Therefore, the washbasin is almost indispensable in our daily life.

[0003] The faucet on the washbasin is generally connected to two water pipes, one for delivering hot water and the other for cold water. However, according to our life experience, before using the faucet to release hot water, the faucet always releases cold water first, and then hot water will be released after waiting for a while. This is because there is cold water in the pipe, and the cold water needs to be released before the hot water can be discharged. However, the cold water released in advance is often discharged directly into the sewer, resulting in a waste of water resources.

[0004] In addition, when we use the sink to wash our hands and faces, we often use hand sanitizer, facial cleanser, soap and other items to help clean. These items will produce foam during the cleaning process, and the foam floats on the water. The drain outlets of common washbasins are at the bottom of the washbasin. Therefore, when draining, the water in the lower layer is discharged first, and the foam is discharged last, which can easily cause foam to remain in the washbasin. Summary of the invention

[0021] Technical effects and advantages of the present invention:

[0022] 1. The present invention connects the open end of the sleeve with the water outlet end of the faucet. Before the faucet releases hot water, the cold water originally in the pipeline flows into the recovery pipe through the sleeve and the hollow handle after being discharged, and finally flows into the water storage tank for storage after being conducted. The water stored in the water storage tank can also be discharged and reused. In this way, the cold water discharged in advance in the pipeline is recovered before the hot water is released, so as to avoid the cold water being directly discharged into the sewer and causing waste.

[0023] 2. The present invention discharges water into the water receiving bucket, and then introduces the water receiving bucket into the hollow channel after being conducted by the water receiving bucket. Under the action of the hollow channel, the water is finally discharged from the drain grooves distributed at various places on the inner wall of the wash basin. The discharged water flushes various places on the inner wall of the wash basin at one time, which is very convenient and quick.

[0024] 3. When there is foam on the hands, the present invention uses the hand-held piece and the iron connector to drive the main handle to move and control the faucet. The surface of the faucet will not be stained with foam, and the iron connector and the hand-held piece can be separated from the main handle to clean the foam on the outer ends of the two, thereby preventing the foam from being stained on the faucet and facilitating cleaning. During cleaning, water will not flow to the outside of the wash basin.

[0025] 4. The present invention pulls the lifting cylinder upward during drainage so that the transverse drainage port at the outer end of the lifting cylinder is located at the water surface. The floating foam on the water surface is therefore gathered at the transverse drainage port along with the water flow and flows into the lifting cylinder through the transverse drainage port, thereby cleaning the floating foam on the water surface and avoiding the floating foam remaining in the wash basin after drainage.

[0026] 5. The present invention installs a foldable support plate on the front side of the storage box. When washing hair, the telescopic rod can be rotated to rotate the support plate to a horizontal state. The user can sit on the top of the support plate to wash hair, and the weight of the body is supported by the support plate. There is no need to squat or bend upright for a long time, which improves the comfort when washing hair. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Refer to the instruction manual Figure 1-13 The present invention provides a water-saving multifunctional wash basin, comprising an installation box 2 and a wash basin 3 for holding water, wherein the wash basin 3 is installed at the top of the installation box 2, and the bottom of the wash basin 3 extends into the interior of the installation box 2, and a faucet 5 is installed at the rear edge of the wash basin 3, and a water storage tank 17 for temporary water storage is provided at the bottom of the interior of the installation box 2, and the discharged cold water is temporarily stored in the water storage tank 17, and a plug pipe 19 is provided inside the water storage tank 17;

[0043] A storage box 8 is fixedly provided at one side edge of the wash basin 3, a hollow shaft 50 is provided at the top of the storage box 8 and is movably connected to the top of the hollow shaft 50 through a bearing, a spring 49 is fixedly provided at the top of the hollow shaft 50, and the other end of the spring 49 is fixedly connected to the top of the storage box 8, and the hollow shaft 50 is driven to rotate by the elastic force of the spring 49, and the top of the insert tube 19 extends into the interior of the hollow shaft 50 and is movably connected to the inner wall of the hollow shaft 50 through a sealed bearing, so as to The water in the hollow shaft 50 is introduced into the water tank 17 through the insert pipe 19. A recovery pipe 47 for recovering cold water is fixedly provided at the outer end of the hollow shaft 50. The recovery pipe 47 is wound around the outer end of the hollow shaft 50. One end of the recovery pipe 47 extends to the top of the wash basin 3 and is fixedly provided with a hollow handle 7. A sleeve 25 for docking with the faucet 5 is fixedly provided at the outer end of the hollow handle 7. The inner diameter of the open end of the sleeve 25 is the same as the outer diameter of the water outlet end of the faucet 5 so that it can be put on the water outlet end of the faucet 5.

[0044] When it is necessary to release hot water through the faucet 5, first pull the hollow handle 7 and drive the recovery tube 47, so that the recovery tube 47 wound and stored in the storage box 8 is pulled out, and the recovery tube 47 drives the hollow shaft 50 to rotate while pulling, and the spring spring 49 is tightened as a result, and the hollow handle 7 is pulled to the bottom of the water outlet end of the faucet 5, and then the sleeve 25 is turned over so that the open end of the sleeve 25 is upwardly sleeved on the water outlet end of the faucet 5, and then the faucet 5 is opened again. After being discharged, the cold water in the pipeline enters the hollow handle 7 through the sleeve 25, and flows along the recovery tube 47 to the hollow shaft 50, and then enters the water storage tank 17 through the insert pipe 19 for storage. In the process of recovering cold water, the sleeve 25 can be pulled out from the water outlet end of the faucet 5 at any time to check whether the released water has become hot. When the cold water in the pipeline is drained, the sleeve 25 can be removed, and the hot water will be discharged from the water outlet end of the faucet 5. At the same time, the elastic force of the spring 49 drives the hollow shaft 50 to rotate and pull the recovery tube 47, so that the recovery tube 47 returns to the storage box 8, and the hollow handle 7 and the sleeve 25 are also pulled back to their original positions. From the above, through the coordinated arrangement of the sleeve 25, the hollow handle 7, the recovery tube 47, and the water storage tank 17, the cold water pre-discharged from the pipeline is received before the hot water is released, so as to avoid the waste caused by direct discharge of the cold water into the sewer. The sleeve 25 and the faucet 5 are detachably arranged, so that the operator can receive the water from the faucet 5 as needed. The coordinated arrangement of the sleeve 25, the hollow handle 7, the recovery tube 47, the spring 49, and the hollow shaft 50 realizes the automatic storage of the recovery tube 47, which is conducive to maintaining the neat appearance of the wash basin.

[0045] The cold water recovered in the water storage tank 17 can be reused, such as Figure 1-3As shown, a sealing plate is provided on the side of the storage box 8 facing the wash basin 3 and is connected to the sealing plate by screws, and a plurality of support rings 48 for reinforcement are fixedly provided in the wall of the recovery pipe 47 .

[0046] In order to drain the water inside the water storage tank 17, the front side of the installation box 2 is provided with an upper sealing door 9 and is movably connected to the upper sealing door 9 through a hinge. A fixing ring 10 is fixedly provided on the front side of the upper sealing door 9. By squeezing the fixing ring 10, air can be pressed into the water storage tank 17 and the water in the water storage tank 17 can be squeezed so that the water therein flows out in the reverse direction. A hemispherical bag 11 with elastic force is fixedly provided at the front end of the fixing ring 10. A connecting pipe connected to the outside is fixedly provided at the outer end of the fixing ring 10. A valve is fixedly provided on the connecting pipe. An air guide hose 18 for conducting air is fixedly provided at the top of the water storage tank 17. One end of the air guide hose 18 is fixedly connected to the upper sealing door 9 and passes through the upper sealing door 9 and is connected to the inside of the fixing ring 10.

[0047] When recycling cold water, the valve on the connecting pipe is in an open state. As the recycled cold water continues to enter, the air inside the water tank 17 is squeezed and enters the fixed ring 10 through the air guide hose 18 and is discharged through the connecting pipe. When the cold water inside the water tank 17 needs to be used, the valve on the connecting pipe is closed, and then the hemispherical balloon 11 is squeezed, so that the air inside the hemispherical balloon 11 and the fixed ring 10 is squeezed into the water tank 17 through the air guide hose 18, thereby squeezing the cold water stored in the water tank 17, so that the cold water flows upward through the insert tube 19 and returns along the original path when it was recycled, and finally flows out from the sleeve 25, so that the cold water recovered in the water tank 17 can be discharged along the original path for secondary use, and when the valve on the connecting pipe is opened again, the hemispherical balloon 11 will rebound.

[0048] In order to conveniently rinse the interior of the wash basin 3, Figure 2 , 6 As shown in Figures 8 and 9, a hollow channel 26 for dispersing water flow is fixedly provided on the inner wall of the wash basin 3. A plurality of water drain grooves 39 are provided at the bottom of the hollow channel 26. Water entering the hollow channel 26 flows down through the water drain grooves 39 to flush the inner wall of the wash basin 3. An inner tube 38 is fixedly provided at the top of the hollow channel 26. The inner tube 38 extends up and down. An outer tube 37 is sleeved on the top of the inner tube 38. The outer tube 37 can rotate around the central axis of the inner tube 38. The inner tube 38 is movably connected to the outer tube 37 through a sealed bearing. A connecting pipe 27 for guiding water flow is fixedly provided at the outer end of the outer tube 37. A sleeve 28 for adjusting the direction is sleeved on one end of the connecting pipe 27 and is movably connected to the sleeve 28 through a sealed bearing. A water receiving bucket 4 for receiving water is fixedly provided on the top of the sleeve 28.

[0049] When it is necessary to rinse the inner wall of the wash basin 3, the connecting pipe 27 is rotated along the horizontal plane to rotate the outer pipe 37. After the connecting pipe 27 rotates, the sleeve 28 fixed at one end of the connecting pipe 27 and the water receiving bucket 4 are moved to below the water outlet end of the faucet 5. Then the sleeve 28 is rotated to drive the water receiving bucket 4 to rotate so that the water receiving bucket 4 is rotated to the open end facing upward, and then the faucet 5 is turned on. The water flowing out of the faucet 5 enters the water receiving bucket 4 and flows along the sleeve 28 and the connecting pipe 27 to the outer pipe 37, and then flows into the hollow channel 26 through the inner pipe 38, and finally flows out through the drain trough 39. A plurality of drain troughs 39 are distributed in the hollow channel 26. The bottom end of the channel 26 disperses the water flow entering the hollow channel 26, and the water flowing out through the drain trough 39 flows along the inner wall of the wash basin 3, thereby cleaning the inner wall of the wash basin 3. The drain troughs 39 are distributed at various places on the inner wall of the wash basin 3. Therefore, in this way, various positions of the inner wall of the wash basin 3 can be flushed at one time, which is very convenient and quick. After flushing, turn off the faucet 5, and then rotate the connecting pipe 27 so that the connecting pipe 27 rotates to a position close to the inner rear wall of the wash basin 3, and drives the position of the sleeve 28 and the water receiving bucket 4 to move, so that the connecting pipe 27 is folded and does not take up too much space.

[0050] In order to prevent the foam on your hands from getting on the outer end of the faucet 5, Figure 6 , 7 As shown, a main handle 6 for faucet 5 is fixedly provided at the outer end of the faucet 5 for easy operation. The faucet 5 is opened or closed and the water temperature of the faucet 5 is controlled by the main handle 6. A notch 32 is provided at one end of the main handle 6. An iron connector 31 is provided inside the notch 32. The front end of the iron connector 31 extends to the front side of the main handle 6 and is fixed with a hand-held piece 30. A slot 34 is provided on the iron connector 31. A magnet sheet 33 for adsorption is provided inside the notch 32. The outer end of the magnet sheet 33 is fixedly connected to the inner wall of the notch 32. The iron connector 31 is clamped at the outer end of the magnet sheet 33 through the slot 34, and the iron connector 31 is adsorbed by the magnetic force of the magnet sheet 33.

[0051] In the middle of washing hands, foam may be stained on the hands. At this time, if the faucet 5 is controlled to be turned on or off, the foam will be stained on the outer end of the faucet 5. When cleaning the faucet 5, water may flow to the outside of the wash basin 3, which is inconvenient. Therefore, a main handle 6 is installed on the faucet 5. The faucet 5 is turned on and off by moving the main handle 6 up and down, and the main handle 6 is turned left and right to control the water temperature discharged from the faucet 5. When there are foam on the hands, if you want to control the faucet 5 through the main handle 6, you can pinch the hand-held piece 30 with your fingers, and the hand-held piece 30 drives the main handle 6 to move. The hand-held piece 30 passes through the iron The connector 31 is connected to the main handle 6, and the iron connector 31 is stuck in the outer end of the magnet sheet 33 through the slot 34, and the magnet sheet 33 is fixed in the notch 32. Therefore, after using the hand-held piece 30, the hand-held piece 30 and the iron connector 31 can be pulled to separate the iron connector 31 from the main handle 6, and the foam on the hand-held piece 30 and the iron connector 31 can be cleaned separately. After cleaning, the iron connector 31 can be reconnected to the magnet sheet 33 and the main handle 6 through the slot 34. This makes it easy to clean the foam, and the water during the cleaning process will not flow to the outside of the wash basin 3.

The top of the adjusting cover 29 is provided with an external drainage port 45. The top sealing plate of the lifting cylinder 36 is provided with two internal drainage ports that are connected from top to bottom. One of the internal drainage ports is provided with a filter screen 44. The filter screen 44 filters the debris in the water. The adjusting cover 29 rotates to connect the external drainage port 45 with one of the two internal drainage ports 41.

[0057] A transverse plate 43 is provided inside the lifting cylinder 36, and both ends of the transverse plate 43 are fixedly connected to the inner wall of the lifting cylinder 36. An adjusting shaft 42 is provided at the top of the transverse plate 43 and is movably connected to the bottom end of the adjusting shaft 42 through a bearing. The top end of the adjusting shaft 42 extends to the top of the lifting cylinder 36 and is fixedly connected to the bottom end of the adjusting cover 29, thereby realizing the rotation of the adjusting cover 29.

[0058] When draining the water inside the wash basin 3, the following drainage methods can be adopted according to the situation:

[0059] Embodiment 1: When soap, facial cleanser and other items are not used and there is no foam on the water surface, rotate the rotating protrusion 46, and drive the adjusting cover 29 and the adjusting shaft 42 to rotate by rotating the protrusion 46, so that the outer drain port 45 on the adjusting cover 29 rotates accordingly. If there are large solid impurities in the water, the outer drain port 45 is rotated to the filter screen 44, and the water flow can pass through the filter screen 44 into the lifting cylinder 36, and the solid impurities will be filtered. If there are no large solid impurities in the water, the outer drain port 45 is rotated to the inner drain port 41, and the water inside the wash basin 3 is directly discharged into the lifting cylinder 36 through the inner drain port 41. The water entering the lifting cylinder 36 then enters the extension pipe 21 through the bellows 35, and is then discharged to the sewer through the downpipe.

[0060] Embodiment 2: Because soap, facial cleanser and other items are used, there is foam on the water surface. At this time, if the traditional drainage method is still used, the water flows vertically when discharged, and the water at the bottom will be discharged first. The foam slowly drops with the water surface. When the water surface drops to the bottom of the wash basin 3, the foam is likely to remain at the bottom of the wash basin 3, and secondary cleaning is required. For this purpose, the following drainage method is required;

[0061] The lifting cylinder 36 is pulled upward by rotating the protrusion 46, and the bellows 35 is extended accordingly. The transverse drain port 54 at the outer end of the lifting cylinder 36 moves upward synchronously with the lifting cylinder 36, so that the transverse drain port 54 moves upward to the water surface. The water surface is located between the inner top and the inner bottom of the transverse drain port 54, and the water flow at the water surface will flow horizontally toward the transverse drain port 54. Therefore, the floating foam on the water surface flows to the transverse drain port 54 with the water flow, and flows into the lifting cylinder 36 through the transverse drain port 54, and finally enters the sewer, realizing the discharge of the floating foam. During the discharge process, the floating foam on the water surface flows horizontally with the water flow at the water surface and flows to the transverse drain port 54. The lifting cylinder 36 is converged until all the floating foam on the water surface flows into the lifting cylinder 36. In the process of cleaning the floating foam, the water surface will drop, and the height of the lifting cylinder 36 will also change accordingly, maintaining the height of the water surface between the internal top and internal bottom of the horizontal drain outlet 54. When the floating foam is cleaned, the lifting cylinder 36 is moved down to the inside of the bottom pipe 20 again, and the water is drained in the traditional way in Example 1. In the above way, the floating foam on the water surface is cleaned before drainage to avoid the floating foam remaining in the wash basin 3 after drainage. In the process of the lifting cylinder 36 moving upward, the bellows 35 plays a limiting role along with the lifting height of the lifting cylinder 36 to avoid the lifting cylinder 36 and the bottom pipe 20 being completely separated.

[0062] When washing your hair in the wash basin 3, in order to relieve the pressure of bending over for a long time, Figure 2 , 13As shown, the storage box 1 is provided with a slider 16 that can adjust the height on the front side and is slidably connected to the slider 16 through a slide rail. The slider 16 is arranged between the two lower sealing doors 14. The slider 16 is provided with a fastening bolt on the front side. The fastening bolt passes through the slider 16 and contacts the slide rail. The fastening bolt is threadedly connected to the slider 16, and the position of the slider 16 is fixed by the fastening bolt.

[0063] A mounting frame 15 is fixedly provided at the front side of the slider 16, and a fixed shaft 51 is provided inside the mounting frame 15. Both ends of the fixed shaft 51 are movably connected to the inner walls of both sides of the mounting frame 15 through damping bearings. Two telescopic rods 13 are fixedly provided at the outer end of the fixed shaft 51, and the sitting posture can be adjusted by adjusting the length of the telescopic rods 13.

[0064] A support plate 12 is disposed at the front side of the mounting frame 15 , a cushion 24 for improving comfort is fixedly disposed at the top of the support plate 12 , and one end of the two telescopic rods 13 facing the support plate 12 is fixedly connected to the bottom end of the support plate 12 .

[0065] In daily life, the wash basin 3 can be used for washing face, hands, and hair. Generally speaking, the height of a common wash basin is about one meter, which is approximately at the waist level of an adult. Therefore, when washing hair, the user needs to stand upright or half-squat with the waist bent to wash the hair so that the head is located above the wash basin 3 for easy washing. However, such a posture can easily cause fatigue in the user's waist and lower limbs. Therefore, before using the wash basin to wash hair, the slider 16 can be slid to adjust the height of the slider 16 according to the height, and then the fastening bolt can be tightened to fix the position of the slider 16, and then the telescopic rod 13 is rotated, and the fixed shaft 51 rotates accordingly, so that the telescopic rod originally in the folded state can be folded. 13. The support plate 12 is unfolded so that the support plate 12 is in a horizontal state, and the side where the cushion 24 is located faces upward. When the support plate 12 is rotated to the horizontal position, the inner bottom end of the mounting frame 15 contacts the telescopic rod 13 to limit its further rotation and maintain the support plate 12 in a horizontal state. Then, the distance between the support plate 12 and the storage box 1 is controlled by extending and retracting the telescopic rod 13. After all adjustments are made, the user can sit on the top of the support plate 12 when washing his hair, with his legs on both sides of the support plate 12, and then bend over to stretch his head toward the wash basin 3. By washing his hair in this way, the weight of the body is supported by the support plate 12, and there is no need to squat or bend over for a long time, thereby improving the comfort when washing his hair.

[0066] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
