Description

The double water device of washing machine

Technical field

The utility model belongs to the drainage arrangement of washing machine, the double water device of particularly a kind of washing machine.

Background technology

At present, the appearance of washing machine has brought very big convenience to people, but so for many years, people have but ignored an important problem when using it, be exactly its single water problems, especially rotary drum washing machine is in the process of laundry, and water generally all is discharged in the sewer.Roller washing machine is also better, can utilize draining pump that the water of discharging is discharged to earlier in the container, is used again.But its first road laundry water is the water of sewage and rinsing clothes to be discharged in the same container together, makes original clear water become sewage, and people often are reluctant to utilize.So today in short supply day by day in water resource and water price sharp rises, must transform the single slope drainage problem that existing washing machine exists.

Summary of the invention

The purpose of this utility model provides the double water device of a kind of washing machine, utilize 3 program control cams of draining to be contained in 1 original cam of replacement in the same rotating shaft, each cam has the contact to be connected with two-way switch, electromagnetic valve, relay, water pump, check-valves, power supply respectively, the task of original 1 cam execution is changed into 3 cams finish, be convenient for people to collect clear water and utilize again.

The utility model is made up of 3 program control cams of draining and two-way switch, electromagnetic valve, relay, water pump, check-valves, power supply, on same axle the

program control cam

1,2,3 of draining is housed, and each cam is respectively equipped with two-

way contact

1 ₁, 2 ₁, 3 ₁With two-way switch K ₁, K ₂, K ₃,

electromagnetic valve

4,5, bidirectional relay 8, water pump 6, check-valves 7, power supply connect.

The utility model has changed the present situation of washing machine drainage, and people are in using the process of washing machine, and the water that can arbitrarily discharge washing machine remain in the container or drain, and water is used again, boosts environmental awareness and improves making full use of of water resource.

The specific embodiment

Shown in Fig. 1-5, the utility model is 3 with the program control cam design of single draining of original mechanical type washing machine, improved cam is the same with the original single cam principle of mechanical type washing machine, only the task that original 1 cam is carried out is changed into the

cam

1,2,3 that stacks and finish, be convenient for people to collect clear water and utilize again.When washing machine carries out water inlet of first road and laundry, two-

way contact

1 ₁, 2 ₁, 3 ₁Intermediate contact E ₁, E ₂, E ₃Be in the peak of cam, intermediate contact E ₁, E ₂, E ₃With intermediate contact F ₁, F ₂, F contact, washing machine begins water inlet and laundry, after finishing, two-

way contact

2 ₁, 3 ₁Intermediate contact E ₂, E ₃Be in the middle place of cam, be in off-position, two-way contact 1 ₁Intermediate contact be in the nadir of cam 1, intermediate contact E ₁With D ₁Connect, power supply is through K ₁, K ₁A is connected with electromagnetic valve 5 sewage is drained, as middle contact E ₁Intermediate contact E when running to cam 1 peak ₁With D ₁The disconnection draining finishes.Intermediate contact E ₁With F ₁Contact enters into into water and laundry state.Intermediate contact E after finishing ₁Be in the middle place and the D of cam 1 ₁With intermediate contact F ₁All do not contact.

This moment two-way contact 2 ₁Intermediate contact E ₂Just running to the nadir of cam 2.Intermediate contact E2 and D ₂Contact, power supply is through K ₂, K ₂B connects electromagnetic valve 4 and water pump 6, and draining begins, as middle contact E ₂When running to cam 2 peaks, intermediate contact E ₂With D ₂Disconnect, F2 contacts with intermediate contact, enters into into water and program for washing.After finishing, intermediate contact E ₂Run to the middle place of cam 2, intermediate contact E ₂, D ₂, F ₂All do not contact, laundry is finished by cam 3 to shutting down, and its principle is the same with cam 2.

As shown in Figure 6,

cam

1,2,3 is provided with two-

way contact

1 ₁, 2 ₁, 3 ₁, two-

way contact

1 ₁, 2 ₁, 3 ₁Connect power supply after the connection; Two-

way contact

1 ₁, 2 ₁, 3 ₁With two-way switch K1, K ₂, K ₃Connect two-way switch K ₁, K ₂, K ₃K _1A, K _2A, K _3APin is connected two-way switch K after being connected to the A line with electromagnetic valve 5, power supply _1B, K _2B, K _3BPin is connected to the B line and is connected with electromagnetic valve 4, and

electromagnetic valve

4,5 is connected with water pump 6, bidirectional relay 8, the power supply of band check-valves 7.

The first road laundry processes of washing machine: water inlet, laundry, draining and intake again, do washing, finish the electric contact 2 of cam 2 and cam 3 by cam 1 ₁, 3 ₁Be in off-position, after cam 1 is finished the work, electric contact 1 ₁Be in off-position, the electric contact 2 of cam 2 ₁Energising, task is changeed draining, water inlet and the laundry processes of being finished second road by cam 2.The electric contact 3 of cam 3 ₁Be in the off-position, after cam 2 is finished the work, the electric contact 3 of cam 3 ₁Energising is finished processes such as draining, water inlet up to shutdown.

Owing to having increased

cam

2,3, that is to say that need increase by two groups of electric contacts finish their combination with corresponding accessory, as water pump 6 (impeller machine is used),

electromagnetic valve

4,5, relay 8 (the cylinder machine is used), check-valves 7 and two-way switch K ₁, K ₂, K ₃

When cam 1 is finished the draining of laundry palpus, drive electric contact 1 ₁Connect two-way switch K ₁, connect water pump 6, bidirectional relay 8, the power supply of electromagnetic valve 4, check-valves 7 again.The principle of

cam

2,3 is the same with cam 1.The user only needs two-way switch K when using washing machine ₁, K ₂, K ₃Fixed on A, the B line just.

The water of first road laundry is drained, and the later water in second road is saved in the container.The user only needs two-way switch K ₁Fix on the A line, two-way switch K ₂, K ₃Fixed on the B line just.Two-

way contact

1 ₁, 2 ₁, 3 ₁Be connected to draining C line.Two-way contact 1 ₁Power line by two-way switch K ₁Connect with the A line, two-way contact 2 is drained the first road water in electromagnetic valve 5 work ₁, 3 ₁Power line by two-way switch K2, K ₃Connect with the B line, electromagnetic valve 4 and water pump 6 work are in the later water row container in first road.

As shown in Figure 6, the draining of roller washing machine is finished by water pump 6, for solving double water problems, need install a two-way relay 8 additional.When two-way contact 1 ₁Intermediate contact E ₁With D ₁Contact, power supply is through two-way switch K ₁, two-way switch K ₁A connects electromagnetic valve 5, and the normally-closed contact of bidirectional relay 8 connects water pump 6 work, sewage is drained, and when second time draining, electric contact 2 ₁Intermediate contact E ₂Contact with D2, power supply is through two-way switch K ₂, K ₂B is communicated with bidirectional relay 8 when connecting electromagnetic valve 4, makes normal battles of bidirectional relay 8 closed, and the power supply closed place that often makes war connects water pump 6 and works, and draining begins.

As shown in Figure 7, the former design of rotary drum washing machine is natural drainage, and here the first road sewage is discharged naturally by it, so need not connect water pump 6 drainings, the second road clear water begins to connect water pump 6 and comes draining.Intermediate contact E ₁With D ₁Contact, power supply is through two-way switch K ₁, K ₁A connects electromagnetic valve 5 drainings.Intermediate contact E ₂With D ₂Contact, power supply is through two-way switch K ₂, K ₂B connects electromagnetic valve 4 and water pump 6 work.
