Description
Technical field
The utility model relates to draining pump/circulating pump technical field, and particularly a kind of impeller the use in washing machine of rotating can enter the draining pump that draining exchanges.
Background technology
Along with the raising of social development and people's living standard, washing machine has become one of household electrical appliances indispensable in people family gradually, and full-automatic pulsator washing machine wash time is short, washes clean, receives the favor of numerous consumer.Conventional wave wheel washer takes lower drainage pattern, and by the Action of Gravity Field of water, directly discharge from sewer, this requires higher to room design.There is certain difference in height on existing studio flat drainage pipeline and ground, particularly external housing design, and drainage pipeline design, in wall, is just needed the mode adopting upper draining, discharged by water by draining pump.
Global energy growing tension simultaneously, energy-saving and emission-reduction theory is rooted in the hearts of the people day by day, and while household electrical appliance bring convenience to people's lives, green home appliance also becomes the emphasis of each household electrical appliances Competition of manufacturers.The water consumption of conventional washer is larger, and for the full-automatic pulsator washing machine of 5 liters, its each standard laundry cycles water consumption is generally raised between 180 liters 150, and the water consumption of washing machine has accounted for 1/4th in household domestic water.In order to saving water resource, more existing housing design, by collecting washings, carry out cycling and reutilization.
Full-automatic pulsator washing machine is while cleaning clothing fast, because creating more greatly more clothes fiber etc. to the frictional force of clothing, be wrapped on draining pump to prevent the rubbish such as the line bits in washings, draining pump stall is caused even to burn, also in order to utilize washings filtration cycle, usually be provided with filter at wash bucket water discharge outlet place, then the water inlet of draining pump is communicated with washing machine drainage mouth, draining pump delivery port connected water outlet pipe.But just cannot continue again to collect after laundry drainage procedure middle filtrator is blocked, because filter is arranged on washing machine internal, also cannot carry out dismounting cleaning.
For solving the problem, existing washing machine drainage mouth is in series with two draining pumps, washing machine drainage mouth connects the water inlet of first row water pump, the water discharge outlet of first row water pump connects the water discharge outlet of second row water pump, the water inlet connected water outlet pipe of second row water pump, when washing machine drainage, first row pump working, second row water air pump inoperative, washings are discharged, when drainage procedure middle filtrator blocks, by programme-control first row water air pump inoperative, second row pump working, because there is certain height on the pipeline of upper drainage system and ground, inside such outlet pipe, some water remains, water is discharged and is used for recoiling to filter by second row water pump, line bits on filter are broken up, can normally work, then second row water pump quits work, first row water pump proceeds draining.Although this structure solves drain washing machine continue row's water problem, need to be realized by two pumps, its complex structure, adds its fault rate, also causes washing machine volume bigger than normal, take up room large, and cost is higher.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of rational in infrastructure, can exchange by intake-discharge pipe, and impeller can bidirectional rotation work, and the use in washing machine realizing exchanging into draining can enter the draining pump that draining is exchanged.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the draining pump that this use in washing machine can enter draining exchange comprises pump case, be arranged on the impeller in described pump case, and impeller rotate can the motor that rotates of rotating, described pump case is made up of pump chamber, first pipeline that can suck or discharge liquid and the second pipe that can suck or discharge liquid.
The use in washing machine of said structure can enter the draining pump of draining exchange, because impeller can rotating, driven by motor vane rotary, namely motor passes through programming in fact, realize the rotating of impeller, like this, due to such vibrational power flow, make the first pipeline and second pipe can serve as the function sucking or discharge liquid, be also, can exchange as water inlet and delivery port, like this, during washing machine drainage, drain pump impeller rotates forward and carries out draining, washings are sucked by draining pump through the first pipeline after filtering, and are discharged by second pipe; When plugged filter, drain pump impeller reverses, and the water in drainage pipeline is sucked by draining pump via second pipe, and is discharged by the first pipeline, carries out backwash to filter.
Further improvement is, described first pipeline and second pipe are arranged on pump chamber both sides in the same way, compared to vertically disposed mode, and the exchange adopting the mode being arranged on pump chamber both sides in the same way to arrange the first pipeline and second pipe can better to realize into draining; Refer to that the first pipeline and the second pipe port away from pump case is towards same direction in the same way.
Further improvement is, in described pump chamber, the first pipeline and second pipe and inwall intersection extend a block arc concentric with pump chamber along duct orientation in pump chamber, have anti-interference gap between the extrados of described block arc and described impeller; Arrange block arc, when its role is to prevent draining pump from working, current flow to water inlet along with the effect of inertia of impeller, affect its flow.
Further improvement is, described first pipeline and second pipe are tangent with pump chamber inwall respectively, and under tangent state, water is discharged along centrifugal force direction at delivery port, and operating efficiency is the highest.
Further improvement is, the ratio range between the distance L between described first pipeline and the center line of described second pipe and impeller radius r is L/2r=0.6 ~ 2, the excessive or too small outlet effect that all can affect discharge pipe line.
Further improvement is, the difference R-r between described impeller radius r and block arc radius R is 0.6 ~ 5mm, and difference is excessive, causes backflow serious, hinders water inlet unimpeded; Difference is too small, and impeller and block arc exist the risk of interfering.
Further improvement is, described motor is the DC brushless motor that can realize rotating.
The beneficial effects of the utility model:
(1) because intake-discharge pipe can exchange, rotating based on impeller realizes the drainage works after filtering and carries out automatic backwash to filter, both water can be collected recycle, and save water resource, make again washing machine have Automatic clearance function, keep smooth and easy draining;
(2) backwash owing to taking a draining pump just can complete draining and filter, the structure of washing machine simplifies greatly, can reduce the volume of washing machine thus, saves space, can also reduce the cost of washing machine;
(3) different to flow, lift demand for different client, under impeller outer diameter adapts to flow change situation, the control of the difference between arc link stopper radius and impeller radius seems particularly important, difference is excessive, idle pipeline is caused to reflux serious, even there will be leakage, difference is too small, there is the risk of interfering with arc link stopper in impeller, verified by great number tested data, the number range that this programme is taked can meet the needs of flow, lift very well, the risk that it also avoid backflow and interfere;
Distance between (4) first pipelines and the center line of second pipe and the ratio between impeller radius are also the key problem in technology points needing to control, verified by great number tested data, the number range that this programme is taked can make discharge pipe line realize optimum outlet effect.
