Description

Self-cleaning water-saving anti-clogging sink

technical field

The invention relates to a kitchen sink, in particular to a self-cleaning water-saving and anti-clogging sink.

Background technique

The sink is a common device in the family kitchen. It is generally a single or side-by-side trough-shaped structure, fixedly installed on the stove, and the bottom of the sink is provided with a drain, and the water is supplied through the faucet to wash vegetables, fruits, dishes, chopsticks and tableware. .

During the cleaning process, most of the food residues are continuously collected into the drain with the water flow. Usually, there is a cup-shaped filter funnel in the drain. For a good filtration effect, for most of them to be relatively large, the existing choice is usually a compromise of 3.5mm. Based on this situation, some rice grains and vegetable dregs will just block the leak hole, resulting in water accumulation in the tank. At this time, artificial use is required. Only by digging the dirty residue by hand can the water pass through, but because the residue is small, it is difficult to clean it out well. It is said that it will block the leaking hole again after a while, and it can only be poured out by lifting the filter bucket by hand after the drainage is completed. Residue, and therefore exposure to residue is unavoidable. Part of the fine residue that passes through the leak hole will continue to accumulate in the drain pipe, especially at the trap of the drain pipe. After a period of time, the drain pipe will also be blocked, and once the drain bend is blocked, it often needs to be removed. After unblocking, it is even more troublesome.

In addition, the cleaning process needs to discharge water through the faucet above the sink. Usually, people need to wash with both hands, and sometimes a large water flow is required during the cleaning process, and sometimes a small water flow is required. It is difficult to adjust the faucet with free hands. Usually people will turn up the faucet at the beginning, which will cause artificial waste of water resources.

This shows, be badly in need of a kind of novel water tank, improve the above problems.

Contents of the invention

The purpose of the present invention is to provide a water tank with good anti-blocking effect, automatic cleaning and water-saving effect.

In order to achieve the above object, the present invention provides a self-cleaning water-saving and anti-clogging sink, which includes a sink, a faucet installed on the sink, a water supply pipe connected to the faucet, and a drain pipe installed under the sink. There is a water divider connected in series, the water divider includes a cylindrical shell, a water seal installed on the upper part of the cylindrical shell, a conical filter screen installed in the center of the lower part of the cylindrical shell, and a conical The power device for filter screen rotation, wherein the water seal is composed of an annular groove connected to the inside of the cylindrical shell and a water sealing cover buckled in the annular groove, the water sealing cover floats on the water surface; the drain pipe is set In the center of the bottom of the cylindrical shell; the inner wall of the cylindrical shell is provided with a scraper in contact with the outer wall of the conical filter screen, and the upper end of the scraper is provided with a slagging outlet. The body is connected to a fixed centrifugal pump, where the rotating shaft of the centrifugal pump passes through the drain pipe and is fixed to the rotating shaft of the conical filter. The tangential port of the centrifugal pump is used as the water inlet to connect to the water supply pipe, and the axial port of the centrifugal pump is used as the water outlet to connect to the faucet. , the inside of the conical filter screen is provided with a brush in contact with it, and the brush is fixed at the bottom of the cylindrical housing.

The self-cleaning water-saving and anti-clogging water tank adopting the technical solution of the present invention has the following characteristics: when the water tank is discharged, the water with residue enters the gap between the water seal cover and the annular groove. When the water volume is large, the water seal cover floats on the water surface , so after floating, the gap with the annular groove can be enlarged, thereby automatically enhancing the drainage function. After the water and residue enter the water separator, the water passes through the conical filter and enters the drain pipe, while the residue is absorbed by the large-area conical filter. Interception, so as to realize the separation of water and residue; when the faucet discharges water, the water in the water supply pipe first passes through the centrifugal pump in the reverse direction, and impacts the blades of the centrifugal pump to rotate, thereby driving the conical filter to rotate through the rotating shaft of the centrifugal pump, so that On the one hand, the speed of the water flow will be reduced, thereby reducing the water output per unit time of the faucet and reducing waste; The scraper enters the slag discharge port, and a small part of the residue stuck in the mesh of the conical filter will be squeezed out of the mesh again under the action of the brush, so the water separator as a whole has good filtering and self-cleaning functions, and the anti-blocking effect it is good.

As a preferred solution, the side wall of the cylindrical shell is cylindrical, the scraper is arranged obliquely toward the slag discharge port, and the end of the scraper is provided with a bent blocking and blanking part, such arrangement has the following The advantage is that the gap formed by the cylindrical side wall and the conical filter is even, and it is more convenient for the residue in the water to move to the scraper driven by the conical filter, and at the same time move to the slag discharge port along the inclined scraper, and then Squeeze into the slag discharge port under the action of blocking the feeding part.

As a preferred solution, the scraper is provided with permeable holes, such a design can make a small part of the water that cannot enter the conical filter screen in time pass through the permeable holes first, and then be drained through the conical filter screen.

As a preferred solution, the slag outlet is connected to a fermenter, and such a design can ferment food residues into organic fertilizers, thereby avoiding waste of food residues.

As a preferred solution, a drain port is provided at the bottom of the fermenter, and the drain port is connected to a drain pipe through a drain pipe. Such a design can drain away part of the water entering the fermenter in time.

As a preferred solution, the side of the water seal cover is provided with comb teeth submerged in water. This design can make the water seal cover have a certain filtering effect, and prevent large residues from entering the water separator and causing slag discharge. Mouth blockage.

As a preferred solution, the cross section of the annular groove is arc-shaped, rectangular or inverted trapezoidal.

As a preferred solution, a sealing cover is also provided in the water tank above the water sealing cover, and the sealing cover is squeezed above the water sealing cover. This design not only facilitates storing water in the water tank, but also prevents further avoiding possible Bad smells pass through, thus enhancing the anti-odor effect.

As a preferred solution, the part of the rotating shaft of the centrifugal pump located in the drain pipe is provided with helical blades, so that when the centrifugal pump rotates, the helical blades can also form a suction effect on the conical filter at the drain pipe, which not only has Enhance the effect of filtration, and also have the effect of scouring the drainpipe, avoiding the precipitation of fine dross.
