Description

A cycle water-saving washing machine

technical field

The utility model relates to a household appliance, in particular to a circulating water-saving washing machine which can fully utilize water resources.

Background technique

In the existing washing machines, the water inlet pipe is generally connected to the washing tub, and the water is discharged in each process during the washing and dehydration process of the clothes, and the water is not reused, resulting in a waste of resources, especially the fully automatic washing machine. Even more so.

Utility model content

The technical problem to be solved by the utility model is to provide a circulating water-saving washing machine which can reuse the water used in the washing machine.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A circulating water-saving washing machine, comprising a washing machine shell and a washing bucket installed in the shell, a water storage tank is also provided between the shell and the washing bucket, and a two-way valve that can control the bidirectional flow of water flow is passed between the water storage tank and the washing bucket. The water pump is connected.

There is also a controllable three-way valve connected between the above-mentioned two-way water pump and the washing tub, valve port one of the controllable three-way valve is connected to the washing tub, valve port two is connected to an external drain pipe, and valve port three is connected to the two-way water pump. There is a movable spool inside the controllable three-way valve. The spool is a cylinder with spherical ends at both ends. There is also a solenoid valve that controls the movement of the spool to the second port and a solenoid valve between the spool and the inner wall of the second valve port. Return spring that moves the spool toward port three.

As an improvement to the above solution, the above-mentioned water storage tanks are 2 or 3 with the same shape, which are respectively arranged on the periphery of the washing tub, and the water storage tanks are connected through the communication pipes at the bottom of the water storage tanks. A water level scale connected with the water storage tank for observing and detecting the water level in the water storage tank is provided on the shell of the washing machine, and a water level detection switch connected to the internal control circuit of the washing machine is provided on the water level scale. An overflow port is arranged on the top of the water storage tank, and the overflow port communicates with the washing bucket.

The utility model has simple structure, can be directly improved on the existing washing machine, and has low cost. When in use, because the sewage discharged after the first wash is dirty, it is generally discharged directly through the controllable three-way valve; the usable water discharged after the last wash is relatively clean and can be used for the first wash in the next wash Washing water can be stored in the water storage tank in advance. In this way, water can save 25% to 30% of water compared with the washing method of washing machine products in the existing way.

Description of drawings

Accompanying drawing 1 is the structural diagram of the embodiment of the utility model; Accompanying drawing 2 is the structural diagram of the controllable three-way valve of the utility model.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the structural principle of the present utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

As shown in Figures 1-2 , the washing machine disclosed in this embodiment includes a washing machine shell 1 , a washing bucket 2 is arranged in the shell 1 , and a water storage tank 3 is installed in the space between the washing bucket 2 and the shell 1 . There are two water storage tanks 3 in this solution, of course, one or more water storage tanks can also be set according to the internal space of various models of washing machines, and they will not be listed one by one here. But its quantity and layout should consider the mechanical balance of the whole washing machine.

The washing machine casing 1 is provided with a water level gauge 32 communicating with the water storage tank 3 for observing and detecting the water level in the water storage tank 3 . The water level gauge 32 is provided with a water level detection switch 33 connected to the internal control circuit of the washing machine. When the water level in the water level gauge 32 reaches the height of the water level detection switch 33, the two poles of the water level detection switch 33 are turned on by the charged ions in the water, thereby generating a signal and transmitting it to the internal control circuit of the washing machine. An overflow port 34 is also arranged on the top of the water storage tank 3 , and the overflow port 34 communicates with the washing tub 2 . The two water storage tanks 3 are communicated through a communication pipe 31 . The water storage tank 3 communicates with the washing tub 2 through a controllable three-way valve 5 and a two-way water pump 4 at the bottom. The controllable three-way valve 5 has a first valve port 51 , a second valve port 52 and a third valve port 53 . Valve port one 51 communicates with the inside of the washing tub 2, valve port two 52 communicates with the external drain pipe, valve port three 53 communicates with the two-way water pump 4, and the two-way water pump 53 directly communicates with the bottom of the water storage tank 3. There is a movable spool 54 inside the controllable three-way valve 5, and the spool 54 is a cylinder with spherical surfaces at both ends. 52 a solenoid valve 56 that moves and a return spring 55 that makes the spool 54 move toward the valve port three 53.

Because the water in the first two times after washing clothes is dirty, it is generally no longer used. At this time, the valve core 54 in the controllable three-way valve 5 is closely attached to the inner hole of the valve port 3 53, so that the sewage directly flows from the valve port 1 51. Into the controllable three-way valve 5, and then discharged from the valve port two 52. Because the last cleaning water after washing clothes is relatively clean, it can be reused. At this time, the electromagnetic valve 56 is automatically activated by the internal control circuit of the washing machine, so that the valve core 54 is moved closer to the valve port 2 52, and the valve port 2 52 is sealed. Simultaneously start the two-way water pump 4 to make water flow from the washing bucket 2 into the water storage tank 3 . The amount of water in the water storage tank 3 can be known from the water level scale 32. When the water amount reaches a certain amount, the water level detection switch 33 is triggered, and the internal control circuit of the washing machine obtains the water level signal through the water level detection switch 33. When the amount of water exceeds the internal capacity of the water storage tank 3 , excess water can flow into the washing bucket 2 from the overflow port 34 . At this moment, the water in the water storage tank 3 can be used as the water for the first pass when washing clothes for the second time. When in use, only need to turn on the washing machine, the internal control circuit of the washing machine automatically starts the two-way water pump 4 and the electromagnetic valve 56 through the signal detected by the water level detection switch 33, so that the water stored in the water storage tank 3 passes through the two-way water pump 4, The controllable three-way valve 5 enters into the washing bucket 2.

Such a cycle goes round and round, making full use of the clean and reusable water produced in the laundry process, greatly improving the utilization rate of water resources, and saving limited water resources.
