Abstract
The utility model relates to an air overflow device for top draining pumps of washing machines. The utility model is characterized in that one end of an air overflow pipe which is made of a plastic corrugated pipe capable of bending is connected with a water inlet pipe, and the other end of the air overflow pipe is connected with a water bucket of a draining pipe at the upper side of a pump body. In this way, air in the water inlet pipe can directly enter the water bucket via the air overflow pipe without entering a pump and is discharged, the diversion of air and water is effectively achieved, and therefore, the phenomena that the existing top draining pump can not immediately drain when switched on and sewage in a barrel can not be completely drained when the existing top draining pump is switched off are overcome.
Description
The utility model relates to the excessive device of air of washing machine Water pumping installation.With start and the drainage performance that improves Water pumping installation.
At present, the draining pump that washing machine adopted that China is numerous, lack the device of air that overflows, cause to use and go up inconvenience, with the more two-tub washing machine of common production quantity is example, and its drainage system is seen Fig. 1, and the water of wash bucket 1 is through draining valve 6, dehydration barrel 9 is by check (non-return) valve 7, and 8 three water routes of overflow pipe are compiled and led to four-way pipe 5 and receive on the Water pumping installation 4.There is following shortcoming in above structure: (one) is when the start draining, usually start Water pumping installation earlier and then open draining valve, at this moment air can enter draining pump by overflow pipe, or enter water pump by the check (non-return) valve of dehydration barrel, because the check valve that check (non-return) valve is a rubber to be made, its elastic force a little less than, be easy to open downwards, generation and suction can be opened check (non-return) valve downwards when Water pumping installation is worked, and make air enter water inlet pipe and draining pump.As everyone knows, centrifugal pump is the centrifugal force that produces when driving liquid in rotation by the impeller that rotates at a high speed, make delivery port produce pressure and water is discharged, simultaneously water inlet the water suction pump in, if but gassy in the water inlet pipe, pump, because gaseous mass is little, the gas of rotation generation centrifugal force is also little at a high speed, so Water pumping installation has a large amount of air to enter in the pump in start often, Water pumping installation often occurs can not the draining phenomenon, sometimes need valve-off to start shooting again and reach three, four times more than, cause the inconvenience in the use.(2) when the water of Water pumping installation will drain, owing to be gas, water mixture in water inlet pipe and the water pump, " snore ... snore " or " silk is taken ... silk is taken " sound appears in the outlet pipe, make water be difficult to drain.
The work bad phenomenon will appear when Water pumping installation start or draining will be use up in order to overcome, the purpose of this utility model provide a kind of can discharge water when Water pumping installation start shooting, the excessive device of air that the interior ponding of pump can drain during shutdown.
In order to realize this purpose, the rubber water inlet pipe of Water pumping installation links to each other with the four-way pipe of washing machine, establishes a pore above the rubber water inlet pipe, has excessive tracheae one end to link to each other with the pore of water inlet pipe, and the other end links to each other with the bucket of drainpipe above the pump housing.The water inlet inner air tube can not enter in the pump and gets rid of after directly entering bucket by excessive tracheae like this, reaches the start and the drainage performance that improve Water pumping installation.
Water pumping installation adopts the advantage behind the above-mentioned excessive device of air: start promptly has water to discharge, and is quick on the draw; Accelerate the interior sewage of bucket during shutdown and drain speed, so that reach more satisfactory effect.
Fig. 1 is original two-tub washing machine drainage system device schematic diagram.
Fig. 2 is a constructional device schematic diagram of the present utility model.
Below in conjunction with Fig. 2 the utility model mounting structure is further described.Among the figure: 11 Water pumping installations, 12 water inlet pipes, 12 excessive tracheaes, 14 buckets, 15 drainpipes.The water inlet pipe 12 of Water pumping installation 11 is to make with the good butyronitrile rubber of corrosion-resistant intensity, above the rubber water inlet pipe is inserted in the lower end of water inlet pipe in the pore with special glue seal, the tracheae upper end of overflowing is enclosed within on the lug of bucket 14 of drainpipe 15, use the glue seal, cylindrical bucket 14 is compressed to concentric structure with interior round drainpipe 15 usefulness plastics, and bucket should exceed drainpipe, so just can realize gas, moisture stream effectively, thereby overcome existing Water pumping installation, when start, when draining immediately or shutdown, sewage can not drain phenomenon in the bucket.
Claims (1)
- The utility model relates to the excessive device of air of washing machine Water pumping installation, a pore is opened in the top that it is characterized in that the draining pump water inlet pipe, insert in the pore of water inlet pipe top the lower end of the excessive tracheae 3 that the crooked plastic film capicitor of employing energy is made, use the glue seal, the other end is enclosed within on the lug of bucket 14 of drainpipe 15, uses the glue seal.Cylindrical bucket 14 be compressed to concentric structure with interior round drainpipe 15 usefulness plastics, and bucket 14 should exceed drainpipe.
