Description

Technical Field

[0001] This utility model relates to the field of water resource recycling, specifically to a household semi-purified water reuse system. Background Technology

[0002] Existing household water-saving solutions often involve significant investment and require renovations, making them less practical. Considering that household water usage can be divided into two categories—water for washing heavily soiled objects and water for washing relatively clean objects (which we'll call semi-pure water)—we can address this issue. Semi-pure water constitutes a larger proportion of total household water usage and requires only filtration; it can be used for anything except drinking water.

[0003] Chinese patent CN105297841A discloses a handwashing sink water recycling device, comprising a handwashing sink, a faucet, a bracket, and a water outlet pipe. The upper end of the water outlet pipe is connected to the water outlet at the bottom of the handwashing sink. The device further includes: a sink drain pipe located below the water outlet pipe, with a flared upper end; an upper drain valve located at the upper end of the sink drain pipe; a water storage tank located below the flared end of the sink drain pipe; and a tank drain pipe and its lower drain valve connected to the bottom of the water storage tank. The inner diameter of the flared end of the sink drain pipe is larger than the outer diameter of the lower end of the water outlet pipe, and the lower end of the water outlet pipe is spaced within the flared end of the sink drain pipe. The lower end of the sink drain pipe is connected to a sewer. Compared with existing technologies, this invention has a simple structure, is easy to install, and convenient to operate. It allows purified water used in the handwashing sink to be stored in a water storage tank for reuse; excessively dirty water is directly discharged into the sewer. It has a significant water-saving effect and strong practicality.

[0004] However, the handwashing sink water recycling device disclosed in CN105297841A requires control of the upper drain valve below the sink when changing the water flow direction, which is inconvenient. Furthermore, used water overflows from the flared end of the sink drain pipe into the water storage tank, causing splashing and polluting the surrounding environment. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a household semi-purified water reuse system.

[0006] According to the present invention, a household semi-purified water reuse system includes: a frame, a water tank body, mounting holes, a three-way valve switch, a transmission system, a three-way valve, a drain pipe, a sewer, and a semi-purified water storage device; The main body of the water tank, the transmission system, the downpipe, and the sewer are installed on the frame; The water tank body is provided with the mounting hole, which is used to install the water inlet faucet and the three-way valve switch; The three-way valve switch is connected to the actuator of the three-way valve through the transmission system; The downpipe is installed on the bottom surface of the water tank body and is connected to the water tank body; The three-way valve is installed on the bottom surface of the main body of the water tank. The inlet A of the three-way valve is connected to the drain pipe, the outlet B of the three-way valve is connected to the sewer, and the reversing port C of the three-way valve is connected to the semi-pure water storage device. The transmission system is installed on the side and bottom of the main body of the water tank, and the transmission system includes a first shaft, a first bevel gear, a second shaft, and a second bevel gear.

Detailed Implementation

[0013] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0014] like Figure 1 As shown, a household semi-purified water reuse system provided by this utility model includes: a bracket, a water tank body 1, a mounting hole 2, a three-way valve switch 3, a transmission system 4, a three-way valve 5, a drain pipe 6, a sewer 7, and a semi-purified water storage container 8. The main body of the water tank 1, the transmission system 4, and the sewer 7 are all mounted on the bracket.

[0015] The main body of the sink 1 is provided with a sink support rim around the opening. Multiple mounting holes 2 are provided on one side of the sink support rim. The mounting holes 2 are used to install water inlet faucets and three-way valve switches 3.

[0016] The three-way valve 5 is installed on the bottom surface of the main body 1 of the water tank. The three-way valve switch 3 is connected to the actuator of the three-way valve 5 through the transmission system 4. When the three-way valve switch 3 rotates 90°, the actuator on the three-way valve 5 rotates 90° through the transmission system 4, the valve core in the three-way valve 5 changes direction, and the outlet of the three-way valve 5 changes.

[0017] A connecting hole is provided at the bottom of the main body 1 of the water tank, and the drain pipe 6 is installed on the bottom surface of the main body 1 of the water tank. Specifically, the drain pipe 6 is installed in the connecting hole, and one end of the drain pipe 6 is connected to the main body 1 of the water tank.

[0018] The inlet A of the three-way valve 5 is connected to the other end of the drain pipe 6, the outlet B of the three-way valve 5 is connected to the sewer 7, and the reversing port C of the three-way valve 5 is connected to the semi-pure water storage device 8.

[0019] The transmission system 4 includes a first shaft 42, a first bearing 43, a second bearing 44, a first bevel gear 49, a second shaft 47, a third bearing 46, a fourth bearing 48, and a second bevel gear 45.

[0020] The first bearing 43, the second bearing 44, the third bearing 46, and the fourth bearing 48 are respectively mounted on the bracket. The first shaft 42 is rotatably mounted in the first bearing 43 and the second bearing 44, and the second shaft 47 is rotatably mounted in the third bearing 46 and the fourth bearing 48.

[0021] One end of the first shaft 42 is fixedly connected to the three-way valve switch 3, and the other end is fixedly connected to the first bevel gear 49.

[0022] The rotation center point of the three-way valve switch 3 is located on the central axis of the first shaft 42, and the center point of the first bevel gear 49 is located on the central axis of the first shaft 42.

[0023] One end of the second shaft 47 is fixedly connected to the second bevel gear 45, and the other end is fixedly connected to the actuator of the three-way valve 5.

[0024] The center point of the second bevel gear 45 is located on the central axis of the second shaft 47.

[0025] The first shaft 43 and the second shaft 47 are perpendicular to each other. The first bevel gear 49 and the second bevel gear 45, which are respectively installed at the ends of the first shaft 43 and the second shaft 47, mesh with each other. When the first bevel gear 49 rotates around its own center point, the second bevel gear 45 is driven by the first bevel gear 49 to rotate around its own center point.

[0026] Determine whether the water in the main body of the water tank 1 is quasi-pure water.

[0027] When it is determined that the water in the main body 1 of the water tank is not quasi-clean water, the three-way valve switch 3 remains closed. At this time, the valve core in the three-way valve 5 does not move, and the inlet A and outlet B of the three-way valve 5 are connected. The water in the main body 1 of the water tank enters the three-way valve 5 through the drain pipe 6 and then enters the sewer 7 connected to the outlet B of the three-way valve 5.

[0028] When it is determined that the water in the main body 1 of the water tank is semi-pure water, the three-way valve switch 3 is rotated to open the three-way valve switch 3. The rotation of the three-way valve switch 3 drives the first shaft 42 to rotate around its own central axis, thereby driving the first bevel gear 49 to rotate around its own center point. The first bevel gear 49 meshes with the second bevel gear 45. The rotation of the first bevel gear 49 drives the second bevel gear 45 to rotate around its own center point, thereby driving the second shaft 47 to rotate around its own central axis. The rotation of the second shaft 47 drives the actuator of the three-way valve 5 to rotate 90°. The valve core in the three-way valve 5 is reversed, and the inlet A of the three-way valve 5 is connected to the reversing port C. The water in the main body 1 of the water tank enters the three-way valve 5 through the drain pipe 6 and then enters the semi-pure water storage tank 8 connected to the reversing port C of the three-way valve 5.

[0029] This invention uses a three-way valve switch 3 connected to the actuator of a three-way valve 5 via a transmission system 4. This allows the opening and closing of the three-way valve switch 3 to be controlled from above the water tank, thus controlling the state of the three-way valve 5. As a result, semi-purified water can selectively enter the sewer 7 or the semi-purified water storage tank 8. The location of the three-way valve switch 3 is convenient for operation. Furthermore, the three-way valve 5 is connected to the drain pipe 6, the sewer 7, and the semi-purified water storage tank 8 respectively. Water from the water tank flows directly into the sewer 7 or the semi-purified water storage tank 8 through the three-way valve 5, avoiding water splashing and ensuring a dry surrounding environment.

[0030] In some feasible implementations, a filter is installed in the drain pipe 6. The filter filters the water effluent from the main body of the water tank 1, so that the semi-pure water storage device 8 collects less impurities in the semi-pure water.

[0031] In some feasible embodiments, the main body of the water tank 1 is provided with a water tank support edge around the opening edge, and reinforcing plates are provided at the bottom of the water tank support edge, the bottom of the main body of the water tank 1, and the side walls of the main body of the water tank 1. The reinforcing plate at the bottom of the water tank support edge increases the structural strength of the water tank support edge and enhances its load-bearing capacity. The reinforcing plate on the bottom plate of the main body of the water tank 1 strengthens the fixing strength between the bottom of the water tank and the three-way valve 5 and the transmission system 4. The reinforcing plate on the side walls of the main body of the water tank 1 strengthens the fixing strength between the side walls of the water tank and the transmission system. The reinforcing plates reinforce the welding and fixing of the water tank support edge, the three-way valve 5, the transmission system 4, and the water tank.
