Problems solved by technology

[0004] The existing waste water is reused to flush the toilet. On the one hand, it is necessary to improve the installation in the toilet water chamber, for example, to install a water level detection device; ;Cause the toilet and washing machine can not be commonly used together, resulting in the reuse of waste water to flush the toilet to use the installation process is too cumbersome

Embodiment 1

[0041] Such as figure 1As shown, the washing machine wastewater reuse system provided in this embodiment includes a water tank 2 for holding the waste water from the washing machine 1, the water tank 2 is connected to the toilet water chamber 3 through a first pipeline, and the toilet water chamber 3 Connect with the tap water pipe 12 through the second pipeline, and the direction from the water tank 2 to the toilet water chamber 3 on the first pipeline is provided with a drain pump and a first drain valve 4 in sequence, and the second pipeline is connected by a tap water pipe 12 The direction to the toilet water chamber 3 is provided with a second drain valve 5 and a sensor detection unit 6. According to the pipeline water flow information detected by the sensor detection unit 6, the opening / closing of the drain pump, the first drain valve 4 and the second drain valve 5 are controlled. closure.

[0042] Specifically, the first pipe and the second pipe communicate at a side c...

Embodiment 2

[0066] Such as figure 2 As shown, in the waste water reuse system for washing machines provided in this embodiment, the water tank 2 is provided with an exhaust port, the position of the exhaust port is higher than the position corresponding to the maximum water level of the water tank, and the distance between the drain pump and the first drain valve 4 is An exhaust pipe 8 is connected to the pipeline, and the other end of the exhaust pipe 8 communicates with the exhaust port;

[0067] Preferably, the diameter of the exhaust pipe 8 is smaller than the diameter of the first pipeline;

[0068] More preferably, the exhaust pipe 8 is provided with an exhaust valve 7, and the exhaust valve 7 is connected with a drainage pump.

[0069] Specifically, when the water tank 2 described in this embodiment is used for the first time or the user cleans the water tank 2 and uses it again, the gas in the first pipeline between the water tank 2 and the drainage pump will enter the drainage ...

Embodiment 3

[0073] Such as image 3 As shown, the difference from the above embodiment is that in this embodiment, the first pipeline is provided with a drain pump, a first drain valve 4 and a second sensor detection unit 15 in sequence from the water tank 2 to the toilet water chamber 3 . Mainly by replacing the water level switch arranged in the water tank 2 with the second sensor detection unit 15 arranged on the first pipeline, it is realized whether the water tank 2 is used up, and the normal operation of the toilet is guaranteed.

[0074] In this embodiment, the second sensor detection unit 15 includes a flow sensor or a pressure sensor, wherein, when the second sensor detection unit 15 is a flow sensor, start the drain pump and the first drain valve 4 in the first pipeline Afterwards, the flow sensor detects the water flow value in the first pipeline, and when the detected flow value is lower than a certain set threshold value, then close the drainage pump and the first drainage v...

Abstract

The invention discloses a washing machine wastewater recycling system and method. The washing machine wastewater recycling system comprises a controller and a water tank for holding washing machine wastewater, wherein the water tank is connected with a containing water cavity of a closestool through a first pipeline; the containing water cavity of the closestool is connected with a tap water pipethrough a second pipeline; a drainage pump and a first drainage valve connected with the controller are arranged in sequence on the first pipeline from the water tank to the containing water cavity ofthe closestool; a second drainage valve and a sensor detection unit connected with the controller are arranged in sequence on the second pipeline from the tap water pipe to the containing water cavity of the closestool; the controller is used for controlling the opening / closing of the drainage pump, the first drainage valve and the second drainage valve according to pipeline water flow information detected by the sensor detection unit. By adopting the washing machine wastewater recycling system and method, intelligent switching of tap water and wastewater supply to the closestool is realized,wastewater stored in the water tank of the washing machine is effectively utilized, and water resources are saved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine wastewater recycling system and a wastewater recycling method. Background technique [0002] At present, the toilets of urban households in my country are flushed with tap water, and each flush requires 6-8 liters of tap water, which wastes water resources and discharges a large amount of sewage. Domestic water in urban households is mainly composed of two parts, one is water for flushing toilets, the other is water for laundry and bathing, and the wastewater produced by laundry is alkaline water, which can meet the requirements for flushing toilets. Therefore, in recent years, research on flushing toilets with waste water produced by laundry etc. has attracted much attention. [0003] The waste water in the prior art is reused to flush the toilet, which is to discharge the water of the washing machine to a water tank, and the water tank is connected to the toil...
