Description

Rinse water collecting and using device for washing machine and method for collecting water therein

technical field

The invention relates to the technical field of water saving, in particular to a washing machine rinsing water collecting and using device for secondary utilization of washing machine wastewater and a water collecting method therein.

Background technique

At present, my country is a country with a large shortage of fresh water. The per capita fresh water resource is one quarter of the world's average. More than half of the more than 600 cities in the country are short of water to varying degrees, and 111 of them are seriously short of water. How to make full use of the existing fresh water resources is an urgent problem to be solved today.

In daily life, washing machines and flushing toilets take up most of the household water. But many families do not make full use of limited fresh water resources, and the very clean rinsing water discharged from the washing machine is poured out in vain, and fails to be used, such as flushing toilets and so on.

However, with the overall improvement of the quality of the whole people, some families collect the rinse water manually to flush the toilet, but this is very troublesome. During the laundry process, it is necessary to pay attention to the process of the washing machine at all times, and carry out cleaning when the rinse water is drained. Collected by hand.

There are other technologies that collect the rinsing water discharged from the washing machine by adding a collection device, but in this technology, the cleanliness of the rinsing water cannot be accurately judged. If the incoming rinsing water is qualified, all the rinsing water will be poured out, which will inevitably cause waste.

Another example is that in some technologies, a collection device is added to the toilet water tank to add intelligent control, but the structure of the toilet water tank needs to be changed. The toilet water tank is generally made of magnetic materials, and it is difficult to change the shape. If it must be changed, the whole toilet water tank must be replaced . And the volume of the toilet water tank is limited, and it is difficult to increase the device. In addition, the water pump needs to be started every time the water in the toilet is replenished, resulting in an obvious behavior of saving water resources and increasing the waste of electric energy, and the frequent start of the water pump causes sound pollution.

It also includes a remote controller to control the single chip microcomputer.

When the user wants to use the collection device and the use device of the present invention to water flowers or wash the car, the single-chip microcomputer is controlled by the remote controller to close the first solenoid valve 81, the second solenoid valve 82, and the third solenoid valve 83. The fourth solenoid valve 84 and the fifth solenoid valve 85 are opened, the water pump 2 works, and the rinsing water in the water collection tank 5 is washed into the car washing and flowering pipeline 4 through the water pump 2 through the second water branch, so that the vehicle or watering can be washed. , Irrigate the green space.

Through the device for collecting and using washing machine rinsing water provided by the present invention, the rinsing water with higher cleanliness discharged from the washing machine can be automatically collected through the collecting device first, and the rinsing water in the water collection tank 5 can be automatically supplied to the toilet water tank through the priority water device can also when there is no water in the water collecting tank 5, by supplementing the municipal water to the toilet water tank in the priority water device 6, reach saving running water resource with this, reduce the purpose of waste water discharge. And no manpower is required in the process, and the water pump 2 does not need to work during the automatic water replenishment process of the toilet tank, and the water pump 2 works only when the water collecting tank 5 collects the rinsing water discharged from the washing machine and uses the device to wash the car and water the flowers, saving resources.

Two valves 66 are correspondingly arranged with two rotary wheels 65 respectively, and the valve 66 of this water collecting tank pipeline 67 is above the valve 66 of this municipal water pipeline 68; Or descend and push against one end of the connecting rod of one of the rotating wheels 65, when driving the corresponding rotating wheel 65 to rotate, make the other end opposite to this end push against one of the long handles of the corresponding valve output handle 661, and drive The valve output handle 661 rotates, and then controls the opening/closing of the corresponding valve 66 . So that when the water level in the priority water device 6 rises or falls, through the rise or fall of the float valve 2, one end of the float valve output handle 63 is driven to pass through one end of the connecting rod of the corresponding rotating wheel 65 to drive the rotating wheel 65 Rotate, and make the opposite end of the connecting rod drive one of the long handles of the valve output handle 661 to open or close the corresponding valve 66, open/break the water collection tank pipeline 67 or the municipal water pipeline 68. When the water level in the preferential water use device 6 drops, the valve 66 of the water collection tank pipeline 67 is preferentially opened, and the water in the water collection tank 5 is preferentially introduced. When there is no water in the water collection tank 5, the water level continues to decline.
