Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment, and more specifically, relates to an intelligent water-saving washbasin. Background Technology

[0002] Washbasins generate wastewater during use, and the type of wastewater varies depending on how it's used. For example, washing your face produces wastewater mixed with cleaning solution; simply rinsing your hands produces relatively clean wastewater; and when using hot water, some cold water will flow out first, and this cold water will also be discharged as wastewater.

[0003] Of the wastewater generated, the cleaner parts can be recycled. However, in current usage environments, this wastewater is directly discharged, leading to a waste of water resources. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent water-saving washbasin that can store relatively clean water from sewage and utilize it in appropriate scenarios.

[0005] This invention discloses an intelligent water-saving washbasin, comprising a basin body and a faucet installed on the basin body, the faucet having a cold water pipe, a hot water pipe, and a return water pipe; a drain pipe for discharging wastewater is provided at the lower end of the basin body; a drain pipe and a water storage pipe are provided on the side wall of the drain pipe; a water storage tank connected to the water storage pipe is installed below the basin body; a water outlet pipe connected to the return water pipe is provided at the lower end of the water storage tank; a piston mechanism for driving water in the water storage tank into the return water pipe is installed inside the water storage tank; a switching sleeve is rotatably connected inside the drain pipe; and a water passage hole for communicating with the drain pipe or the water storage pipe is provided on the side wall of the switching sleeve.

[0006] As a further improvement of the present invention, the faucet is equipped with an intelligent panel; electric valves are respectively installed on the cold water pipe and the hot water pipe; and a temperature sensor for detecting the water temperature is installed inside the faucet.

[0007] As a further improvement of the present invention, the piston mechanism includes a float plate that is longitudinally and slidably connected to the water tank and floats on the liquid surface, and a stop plate that is slidably connected to the float plate in the horizontal direction; when the stop plate is at the inner limit position of the float plate, there is a gap between the stop plate and the inner wall of the water tank; when the stop plate is at the outer limit position of the float plate, the stop plate is sealed and abuts against the water tank.

[0008] As a further improvement of the present invention, an overflow pipe is provided on the upper part of the side wall of the water storage tank.

[0009] As a further improvement of the present invention, a drive disc for driving the abutment plate is rotatably connected inside the float plate; a connecting rod extending to the bottom of the water storage tank is coaxially arranged at the lower end of the drive disc; a rack distributed axially is arranged on the side wall of the connecting rod; and a drive gear capable of meshing with the rack is rotatably connected below the water storage tank.

[0010] As a further improvement of the present invention, the upper end of the drive disk is provided with an annular groove; the abutment plate is provided with a sliding column that slides in the annular groove; the annular groove has a proximal point close to the center of the drive disk and a distal point far from the center of the drive disk.

[0011] As a further improvement of the present invention, a drive shaft that rotates synchronously with the drive disc in the circumferential direction is rotatably connected inside the water storage tank; the drive shaft is connected to the switching sleeve in a transmission connection.

[0012] As a further improvement of the present invention, a motor is fixedly connected to the bottom of the basin; an inlet gear and a switching gear are provided on the output shaft of the motor; a first ratchet mechanism is provided between the inlet gear and the output shaft of the motor; a second ratchet mechanism is provided between the switching gear and the output shaft of the motor; the first ratchet mechanism and the second ratchet mechanism have opposite transmission directions; the inlet gear is driven by the drive gear; and the switching gear is driven by the switching sleeve.

[0013] As a further improvement of the present invention, the lower end of the water storage tank is rotatably connected to a sealing sleeve; the connecting rod is sealed and inserted into the sealing sleeve.

[0014] Compared with existing technologies, the advantages of this invention are: this solution controls the faucet through an intelligent panel, making the temperature more precise, and it is equipped with multiple working modes to adapt to different usage scenarios, making it intelligent and reliable.

[0015] This solution allows users to store relatively clean water that they discard and use it in specific situations, preventing the water from being directly discharged as sewage, thus enabling water resources to be recycled, saving water resources, and avoiding waste.

[0016] This design utilizes the cooperation of a float plate and a backing plate. When the backing plate is at its inner limit position, both the float plate and the backing plate move upwards as more water enters the storage tank, ensuring that the float plate remains at the top of the liquid surface and that no air is trapped between the float plate and the liquid surface. This prevents air from entering the return pipe and causing the faucet to stop flowing water, thus affecting its normal operation. When the backing plate is at its outer limit position, both the backing plate and the float plate are sealed against the storage tank. As the backing plate and the float plate move downwards, they compress the water, allowing it to flow out of the faucet through the return pipe for recycling.

[0017] The drive disc in this solution can drive the movement of the support plate, allowing the support plate to switch between two positions. It can also change the engagement state between the rack and the drive gear. When the rack and the drive gear are not engaged, the float can float freely with the liquid surface. When the rack and the drive gear are engaged, the drive gear can drive the float to move downward, forcing water to flow out of the faucet through the return pipe.

[0018] This solution uses a switching sleeve to change the flow direction of sewage from the drain pipe, allowing sewage to either enter the sewer directly through the drain pipe or enter the water storage tank through the storage pipe. The switching sleeve can also drive the drive shaft to rotate synchronously, causing the drive disc to rotate circumferentially and change the position of the abutment plate.

[0019] In this solution, the motor can drive the float to move downwards when it operates in the forward direction, allowing water in the storage tank to flow out of the tap. When the motor operates in the reverse direction, it drives the switching sleeve to rotate, changing the direction of sewage flow. This eliminates the need for multiple motors, reduces power components, saves costs, and allows one motor to perform multiple functions without causing interference. Attached Figure Description

Detailed Implementation

[0027] Specific Implementation Example 1: Please refer to... Figure 1-6 A smart water-saving washbasin includes a basin body 1 and a faucet 2 installed on the basin body 1. The faucet 2 has a cold water pipe 22 connected to a tap water pipe, a hot water pipe 23 connected to a water heater, and a return water pipe 24. A drain pipe 11 for discharging wastewater is provided at the lower end of the basin body 1. A drain pipe 12 and a water storage pipe 13 are provided on the side wall of the drain pipe 11. A water storage tank 3 connected to the water storage pipe 13 is installed below the basin body 1. A water storage connection pipe 33 connected to the water storage pipe 13 is provided on the upper part of the side wall of the water storage tank 3. A water outlet pipe 32 connected to the return water pipe 24 is provided at the lower end of the water storage tank 3. A piston mechanism is installed in the water storage tank 3 to drive the water in the water storage tank 3 into the return water pipe 24. A switching sleeve 5 is rotatably connected in the drain pipe 11. A water passage hole 51 that can communicate with the drain pipe 12 or the water storage pipe 13 is provided on the side wall of the switching sleeve 5.

[0028] At the same time, the water passage 51 is connected to only one of the drain pipe and the water storage pipe 13; the drain pipe 12 is connected to the sewer; when the water passage 51 is connected to the drain pipe 12, the sewage in the basin 1 will flow into the sewer through the drain pipe 12; when the water passage is connected to the water storage pipe 13, the water in the basin 1 will enter the water storage tank 3 through the water storage pipe 13.

[0029] When a user needs hot water, they turn on tap 2. However, due to the characteristics of the water heater, tap 2 initially dispenses a portion of cold water. Normally, this cold water is flushed away as wastewater, resulting in water waste.

[0030] The faucet 2 is equipped with a smart panel 21; electric valves are respectively installed on the cold water pipe 22 and the hot water pipe 23; and a temperature sensor for detecting the water temperature is installed inside the faucet 2.

[0031] The piston mechanism includes a float plate 6 that is longitudinally sealed and slidably connected to the water storage tank 3 and floats on the liquid surface, and a stop plate 7 that is slidably connected to the float plate 6 in the horizontal direction. When the stop plate 7 is at the inner limit position of the float plate 6, there is a gap between the stop plate 7 and the inner wall of the water storage tank 3. Water entering the water storage tank 3 through the water storage pipe 13 will flow into the area below the float plate 6 through the gap. The stop plate 7 and the float plate 6 always float on the liquid surface in the water storage tank 3. When the stop plate 7 is at the outer limit position of the float plate 6, the stop plate 7 is sealed against the water storage tank 3. The downward movement of the float plate 6 and the stop plate 7 will force the water in the water storage tank 3 to enter the return water pipe 24.

[0032] An overflow pipe 31 is provided on the upper part of the side wall of the water storage tank 3. The overflow pipe 31 is connected to the sewer. When the water in the water storage tank 3 is higher than the overflow pipe 31, the water flows from the overflow pipe 31 into the sewer for discharge, thus preventing excessive water in the water storage tank 3.

[0033] The float 6 is rotatably connected to a drive disc 8 that drives the abutment 7 to move; the lower end of the drive disc 8 is coaxially provided with a connecting rod 82 extending to the bottom of the water storage tank 3; the side wall of the connecting rod 82 is provided with a rack 821 distributed along the axial direction; the bottom of the water storage tank 3 is rotatably connected to a drive gear 43 that can mesh with the rack 821.

[0034] When the abutment plate 7 is at the inner limit position of the float plate 6, the rack 821 is not engaged with the drive gear 43, and the float plate 6 and the abutment plate 7 can move freely up and down; when the abutment plate 7 is at the outer limit position of the float plate 6, the rack 821 is engaged with the drive gear 43.

[0035] There are two racks 821, which are centrally symmetrically distributed.

[0036] The upper end of the drive disk 8 is provided with an annular groove 81; the abutment 7 is provided with a sliding column 71 that slides in the annular groove 81; the annular groove 81 has a proximal point 812 near the center of the drive disk 8 and a distal point 811 far from the center of the drive disk 8.

[0037] When the sliding rod 71 is located at the proximal point 812, the abutment plate 7 is located at the inner limit position of the float plate 6; when the sliding rod 71 is located at the distal point 811, the abutment plate 7 is located at the outer limit position of the float plate 6.

[0038] The water storage tank 3 is rotatably connected to a drive shaft 9 that rotates synchronously with the drive disc 8 in the circumferential direction; the drive shaft 9 is connected to the switching sleeve 5 in a transmission connection.

[0039] When the water inlet 51 is directly opposite the drain pipe 12, the sliding rod 71 is located at the distal point 811; when the water inlet 51 is directly opposite the water storage pipe 13, the sliding rod 71 is located at the proximal point 812.

[0040] The drive disk 8 has a non-circular rotating insertion hole 83 at its center; the drive shaft 9 is inserted into the rotating insertion hole 83, so that the drive shaft 9 and the drive disk 8 rotate synchronously in the circumference and slide relative to each other in the axial direction.

[0041] The drain pipe 12 and the water storage pipe 13 are symmetrically distributed; the annular groove 81 has two symmetrically arranged proximal points and two symmetrically arranged distal points, and the proximal points and distal points are arranged alternately.

[0042] The transmission ratio between the switching sleeve 5 and the drive shaft 9 is 2 to 1. Thus, when the switching sleeve 5 rotates 180°, the drive shaft 9 rotates 90°, thereby achieving the switching.

[0043] A motor 4 is fixedly connected to the bottom of the basin body 1; an inlet gear 41 and a switching gear 42 are provided on the output shaft of the motor 4; a first ratchet mechanism is provided between the inlet gear 41 and the output shaft of the motor 4; a second ratchet mechanism is provided between the switching gear 42 and the output shaft of the motor 4; the first ratchet mechanism and the second ratchet mechanism have opposite transmission directions; the inlet gear 41 is connected to the drive gear 43; and the switching gear 42 is connected to the switching sleeve 5.

[0044] When motor 4 is working in the forward direction, motor 4 drives the water inlet gear 41 to rotate, while the switching gear 42 does not rotate; when motor 4 is working in the reverse direction, motor 4 drives the switching gear 42 to rotate, while the water inlet gear 41 does not rotate.

[0045] The lower end of the water storage tank 3 is rotatably connected to a sealing sleeve 34; the connecting rod 82 is sealed and inserted into the sealing sleeve 34.

[0046] The drive gear 43 and the water inlet gear 41 are connected by a first synchronous belt; a connecting shaft is rotatably connected to the bottom of the basin 1; a switching shaft is rotatably connected to the lower end of the switching sleeve 5 and is connected to the connecting shaft by a second synchronous belt; a switching connecting gear that meshes with the switching gear 42 is provided on the switching shaft; the switching shaft and the drive shaft 9 are connected by a third synchronous belt.

[0047] The basin 1 is mounted on the cabinet (not shown in the figure), and the various components are mounted inside the cabinet.

[0048] The smart panel 21 is equipped with a cold water button, a rinse button, a hot water button, a return water button, a heating button, a cooling button, and a display screen; the display screen shows the current water temperature and the set water temperature. The set water temperature can be adjusted using the heating and cooling buttons.

[0049] When the hot water button is pressed, the electric valves on the cold water pipe 22 and the hot water pipe 23 open to the corresponding size according to the ratio, so that the cold water and hot water are mixed.

[0050] However, in the initial stage, cold water flows out of the hot water pipe 23. At this time, the motor 4 works in reverse. The motor drives the switching sleeve 5 to rotate 180° through the switching gear 42, so that the water passage 5 rotates to connect with the water storage pipe 13. During this process, the switching sleeve 5 drives the drive shaft 9 to rotate 90°, so that the sliding column 71 is located at the proximal point 812, the abutment 7 moves to the inner limit position of the float 6, and the rack 821 does not mesh with the drive gear 42.

[0051] Then, the cold water in the hot water pipe 23 will enter the water storage tank 3 through the drain pipe 11. As the water in the water storage tank 3 increases, the float plate 6 will gradually move upward in sync. When the liquid level in the water storage tank 3 is higher than the overflow pipe 31, there is too much water in the water storage tank 3. After that, the water entering the water storage tank will flow into the sewer through the overflow pipe 31 for discharge.

[0052] When the temperature sensor detects that the water flowing from the faucet 2 has reached the set temperature, the motor 4 reverses its operation. The motor drives the switching sleeve 5 to rotate 180° through the switching gear 42, so that the water passage 5 rotates to connect with the drain pipe 12. During this process, the switching sleeve 5 drives the drive shaft 9 to rotate 90°, so that the sliding column 71 is located at the centroid 811, the abutment 7 moves to the outer limit position of the float 6, the abutment 7 seals against the water storage tank 3, and the rack 821 meshes with the drive gear 42.

[0053] Afterwards, the wastewater used by the user will flow into the sewer through drain pipe 12.

[0054] When the user needs to rinse their hands, they can press the rinse button, and the motor 4 will work in reverse, so that the relatively clean wastewater generated during hand rinsing will flow out into the water tank 3 for storage (the working process is the same as the above process, and will not be described in detail here).

[0055] When a user needs to clean heavily soiled items such as rags, razors, or mops, pressing the return water button deactivates the electric valve on the cold water pipe 22, allowing the motor 4 to rotate in the forward direction. The motor 4 drives the drive gear 43 to rotate, which meshes with the rack 821. This causes the connecting rod 82 and the drive disc 8 to move downwards. The drive disc 8 then drives the abutment 7 and float 6 to move downwards simultaneously, squeezing the water in the storage tank 3 and forcing it to flow through the return water pipe 24 from the faucet 2 for recycling. When the water in the storage tank 3 is depleted, the electric valve on the cold water pipe 22 opens, replacing the return water pipe 24.
