Detailed description of the invention
Exemplary embodiment of the present invention is shown in the accompanying drawings, and hereafter will be described in greater detail, in which:
Fig. 1 shows the schematic diagram of household appliance；
Fig. 2 shows the schematic diagrames of the recycling pumping system during discharge pumping；And
Fig. 3 shows the schematic diagram of the recirculation pump system during recycling pumping.
Specific embodiment
Fig. 1 is shown as the schematic diagram of the washer-dryer of the substitution of general household appliance 100.Household appliance 100 includes
For clothing to be packed into the appliance door 125 of household appliance 100.Clothing is washed in household appliance and is then dried.Family
It include the detergent disperser pallet 123 that can be drawn out with utensil 100, various liquids are inserted the detergent disperser support
In disk, during washing or drying process, the various liquids are supplied to clothing by means of water flow.Detergent disperser
Pallet 123 is, for example, the drawer type plastic components being drawn out with wash bowl.
Fig. 2 shows have flap 107- during the direction discharge pumping along discharge pumping is located at the water 103 in bucket 105
1, the schematic diagram of the recirculation pump system of 107-2 and 107-3.Water or cleaning solution 103 for cleaning clothing is in the washing process phase
Between be located at bucket 105 in.
In lower area, bucket 105 includes bottom compartment 113, and water or cleaning solution 103 are gathered in the bottom compartment 113 due to gravity
In.Flap 107-3 is arranged on bottom compartment 113.Flap 107-1,107-2 and 107-3 opened according to the flow direction of water or
It closes.
Flap 107-3 has the pivoting point on edge disposed thereon, so that can be realized in recycling pumping operation from bucket
105 suction.In order to reliably mutually distinguish different functions, flap 107-3 is that elasticity pre-tightens, so that flap 107-
3 are closed during pumping circulation is discharged, that is, discharge pumping path is unlimited, and it is closed for recycling pumping path.
The filter inlet 109 of filter element 117 is located on the downside of bottom compartment 113.Filter element 117 was used for drainage.
Filtered water 103 is recycled pump hose 119 and guides around bucket 105, and the outlet on the upside by being located at bucket 105 is fallen
Onto clothing.Water 103 is discharged by passing away 111 from bucket 105.
Pump 101 and its driving be constructed such that they can along be discharged pumping direction the first direction of rotation along and
It is operated along second direction of rotation in recycling pumping direction.The impeller of pump 115 of pump 101 is by axially or partly axially real
It applies, so that reverse rotation direction also causes the direction of transport Stream to invert.When reverse rotation direction, the geometry of impeller of pump
Axial part makes the flowing that can carry out these different directions.The outlet 121 on recycling pumping direction of pump 101 is located at bottom compartment
In 113.On discharge pumping direction, water 103 is inhaled by outlet 121.
Water is discharged on a flow direction, and water recycles in the loop on another flow direction.Recycling
Pumping system includes three elastic flap 107-1,107-2 and 107-3, and three elastic flaps are according to the rotation for pumping 101
Turn direction and open or close.In discharging operation, flap 107-1 is opened and flap 107-2 and 107-3 are closed.
Fig. 3 shows showing for the recirculation pump system during pumping the water 103 in bucket 105 along recycling pumping direction recycling
It is intended to.The recycling pumping of cleaning solution accelerates the wetting of clothing when washing process starts, and improves the washing in washing machine
Ability.
In recycling pumping operation, flap 107-1 closure, and flap 107-2 and 107-3 are opened.It is pumped in recycling
On direction, by filter element 117, foreign matter is captured water flowing in filter element 117.After the deposition of the foreign matter, water
It flows through recirculation pump hose 119 and is supplied again to bucket 105.Flap 107-3 is located under water level, to also ensure that again
Recycle pumping operation.
Not only can expectation recycle pump function when using recycling pump function circuit, but also can in order to rule
Prophylactically cleaning recycles pumping system and uses the circuit for recycling pump function at the interval of rule.Especially not to using
In the open recycling pumping system of person, the cleaning and back scrubbing function can be used for any possible foreign matter being transported to filter element
In 117 and for preventing from blocking.Hereby it is achieved that foreign matter filtering or blocking it is loose.
Only individually pump 101 be used to recycle pumping system.Utilize the auxiliary of Elastic valve clack 107-1,107-2 and 107-3
It helps to realize other function.Compared with traditional recycling pumping system, which, which realizes, is guaranteeing two
Additional driving motor is saved while different operating function.In addition, being realized compared with traditional recycling pumping system
More compact structure.
Provide additional advantage, for example, offer filtering foreign matter function and foreign matter failure active correction.Filtering is single
Member can be open to user, or is done so as to that foreign matter can be stored in the their entire life of utensil.
Recirculation pump system is integrally formed various function application.On the one hand, pump 101 realizes discharge pumping and recycling
Pumping, and on the other hand, provide the activity event in the functional sequence for handling two other functions of foreign matter and correction
The function of barrier.The integrated of pump 101 can be realized in light mode.These specific functions mean the recycling pumping system
Particularly suitable for integrated pumping system, in integrated pumping system, pump or only restricted cannot be approached by pumping 101 user
Ground is blocked close to pump, such as in order to correct.
In conjunction with shown by each embodiment of the invention and all features of explanation can be in present subject matter with different
Combination provides, to realize its advantageous effects simultaneously.
Protection scope of the present invention proposes by claim, and be not limited to illustrate in specification or it is shown in the accompanying drawings
