Description

Household water-saving device

Technical Field

Relates to a civil building water supply and drainage technology, in particular to a household water-saving water supply and drainage system.

Background

With the improvement of the living standard of residents, the daily water consumption of families is increased year by year, and simultaneously, a large amount of domestic wastewater is generated, so that resource waste and environmental pollution are caused. In domestic wastewater, a large amount of wastewater can be recycled, particularly wastewater generated by rinsing of a washing machine and wastewater generated by a reverse osmosis water purifier. Because the amount of waste water generated in the rinsing process of the washing machine is large, and the waste water generated in the rinsing process only contains a small amount of detergent; and the wastewater generated by the reverse osmosis water purifier has no difference with tap water except high mineral content. So that the waste water generated from rinsing and the waste water generated from the water purifier can be completely used for flushing a toilet, washing a mop, etc. In order to recycle the waste water, containers such as a water tank are often used to collect the waste water, and the waste water is taken out of the containers when the waste water is used. This method is complicated and results in unnecessary waste of space in the kitchen or toilet.

Preferably, the outlet of the overflow pipe and the set highest liquid level of the water storage barrel are positioned on the same horizontal plane, so that the waste water collected in the water storage barrel can flow out through the overflow pipe when the waste water continuously flows into the water storage barrel after reaching the set highest liquid level.

Furthermore, three water gaps are arranged on the three-way valve and respectively comprise a waste water gap, a clean water gap and a water outlet, wherein the waste water gap is communicated with the inside of the water storage barrel, the clean water gap is communicated with a tap water pipe, and the water outlet is communicated with a water inlet pipe of equipment for recycling waste water.

Furthermore, a device for measuring the liquid level inside the water storage barrel is arranged on the three-way valve.

Preferably, the device for measuring the liquid level on the three-way valve is a floating ball.

Further, when water is in the water storage barrel, the floating ball is supported by the water surface, the waste water port of the three-way valve is communicated with the water outlet, and the water purifying port is closed; when no water is in the water storage barrel, the floating ball is lowered to the bottom of the water storage barrel, the water purifying port of the three-way valve is communicated with the water outlet, and the waste water port is closed.

Preferably, the waste water port and the water outlet of the three-way valve are positioned at the lower part of the water storage barrel, so that water in the water storage barrel can completely flow out.

Furthermore, the lower part of the water storage barrel is provided with a capacity increasing water port, so that the water storage barrel can be connected with one or more capacity increasing barrels through the capacity increasing water port, the capacity of storing waste water is increased, and the installation flexibility is improved.

Preferably, when the water storage barrel and one or more capacity-increasing barrels are connected together, the water storage barrel and the capacity-increasing barrels are positioned on the same horizontal plane.

Further, the water storage barrel and the capacity increasing barrel are arranged on the top of the kitchen or the toilet.

The household water-saving device can automatically store part of recyclable waste water generated in daily life, and is used for flushing toilets or washing mops and other places which have low requirements on water quality; because the common household kitchen and the toilet have a plurality of sewer pipes at the top, the ceiling can be arranged in the toilet and the kitchen during common household decoration for the sake of beauty and convenience for cleaning in later period, the sewer pipes at the top are shielded, and at the moment, a space is formed between the ceiling and the cement top of a room; the invention utilizes the self pressure of the drainage system of the washing machine and the drainage system of the water purifier to send the generated wastewater into the water storage barrel and the capacity increasing barrel for storage, and simultaneously utilizes the pressure generated by the height difference between the water storage barrel and the water using equipment to send the stored water into the water using equipment without additional power or electric energy; in addition, the use does not need the control or operation of a user, and the device has the characteristics of simple and convenient use; the household water-saving device can effectively reduce the domestic water consumption, save the daily expenditure and reduce the pollution to the natural environment.

The invention will be further explained with reference to the attached drawings.
