In clothes drier, use condensate pump, it will evaporate from washing clothes to be dried and the condensate pump of then condensation is within the condenser delivered in condensed fluid container.Condensed water can be delivered to outflow opening or be used for cleaning the parts of clothes drier by condensed fluid container.But condensed water typically has foreign matter---as fine hair, hair or washing agent residue etc., it can block or adhere to condensate pump.Like this, such as hair can to deposit on the axle being exposed to condensed water and to hinder or even hinder the rotation of axle.Washing agent residue can cause crust, and it hinders the running of pump equally.
Summary of the invention
Task of the present invention is to provide the sane especially of housed device and for the insensitive especially feasible program of the foreign matter in liquid to be conveyed.
Described task is solved by the housed device with liquid pump, and wherein liquid pump has cup, main chamber and air pump, wherein,
-cup has the inlet for injecting liquid;
-cup and main chamber are connected to each other by break-through mouth, and described break-through mouth is darker than inlet in running state;
The pressure port that-main chamber has the exhaust port for discharging liquid and is connected with air pump;
-being provided with and controlling the valve element of liquid level height wearing passage port, described valve element arranges and arranges and is used for closing break-through mouth along with the maximum fluid height reached in main chamber;
-wherein on cup or in cup, be provided with at least one liquid surface height sensor, reaching of the activation level of the liquid in cup can be sensed by means of at least one liquid surface height sensor described;
-wherein liquid pump arrange for activating air pump along with reaching activation level on the endurance determined.
The use tool according to the present invention of described liquid pump has the following advantages: described liquid pump also can work when not being exposed to the rotary component of liquid and therefore can not or be difficult to adhere to.In addition can determine the size of opening in wide scope, thus also can avoid blocking.
Such as can run housed device or its liquid pump in the following way:
First from following: the liquid level height (also referred to as fluid level) in main chamber is positioned at below its maximum fluid height (initial state).Now, liquid to be conveyed is directed in cup by inlet, such as, at the condenser run duration of clothes drier.Because also do not reach the maximum fluid height of main chamber, thus break-through mouth be open and the basic upper reaches of liquid injecting cup go out to main chamber.Therefore, in cup, do not occur the liquid level height raised, but a little liquid may remain in cup.In main chamber, liquid level height raises subsequently, or rather, until reach the maximum fluid height of main chamber.
If meet or exceed the maximum fluid height of main chamber, then the valve element controlling liquid level height is closed break-through mouth and is accumulated in now in cup by the liquid that inlet flows in cup.Thus, the liquid level height of the liquid in cup raises again.If the degree ground like this of the liquid level height in cup raises, make to reach predetermined liquid level height (" activation level "), then this detects by means of the liquid surface height sensor be arranged on cup or in cup.Liquid surface height sensor exports corresponding signal, activates air pump accordingly.Air is pumped in main chamber by pressure port by air pump, and the pressure in main chamber is improved.Liquid is squeezed out by exhaust port and such as can be transported to outflow opening or clean container thus.Therefore the liquid level height in main chamber reduces again.The valve element controlling liquid level height keeps a period of time in its operating position or sealing station, such as, because it is remained closed by the overvoltage generated by air pump.Air pump keeps activating on the endurance determined.
If air pump deexcitation, then can reduce the overvoltage in main chamber, especially balance with external pressure.At the latest in overvoltage reduction, especially pressure balanced moment, the valve element controlling liquid level height turns back in its initial state, and break-through mouth is switched on again.Thus, the liquid be first gathered in cup flows in main chamber, and the liquid flowing through inlet subsequently flows in main chamber, can again implement process described above subsequently.
A preferred expansion scheme is, the valve element controlling liquid level height is float.By float, it can be forced on break-through mouth from reaching maximum fluid height with liquid level height motion especially simply, and reach through hole closed by float thus.Along with liquid level height decline, float due to its deadweight automatically downward away from break-through mouth.
At this, so can be regulated weight or the quality of float by simple mode, the extruding force of the counterproductive (especially upwards) weight being less than caused by the overvoltage in main chamber between liquid pump active period.Especially, float can be hollow body, to realize the high extruding force acted on break-through mouth.
Another preferred expansion scheme is, the valve element, the especially float that control liquid level height are spherical.Guiding that is bothersome and easily fault can be saved thus.
Another preferred expansion scheme is, break-through mouth has the sealing seat of valve element, especially float for controlling liquid level height on its side towards main chamber.Which improve sealing and accurately closing of break-through mouth can be realized.
But liquid pump is not limited to use float.Like this, alternative float also can use active operation, such as with the valve that motor mode is moved, such as, trigger described valve closure break-through mouth by the signal of the liquid surface height sensor of detection maximum fluid height.Valve equally can time controling ground or such as reopen break-through mouth when reaching minimum fluid height in response to the signal of liquid surface height sensor.
Another preferred expansion scheme is, is preregulated (time activation) endurance for activating the endurance of the determination of air pump.Such as can determine the described preregulated endurance by means of clock or other times control gear.Endurance preferably so regulates, and makes to form the significant, especially substantially emptying completely of main chamber.Endurance such as can experimentally try to achieve.Described expansion scheme can especially steadily and surely and realize inexpensively.
A kind of alternative expansion scheme is, is until liquid level height in main chamber reaches the endurance of predetermined minimum fluid height experience for activating the endurance of the determination of air pump.Can guarantee like this until minimum fluid height emptying.For this reason, main chamber such as can be equipped with liquid surface height sensor, described liquid surface height sensor identification minimum fluid height and export corresponding signal subsequently, can deexcitation based on described signal air pump.
Air pump especially can so construct, and makes in its state in deexcitation (air pump of deexcitation), air on the pressure side and between suction side to be passed through at it.Thus, between pressure port and surrounding atmosphere, produce unlimited air passageways when air pump deexcitation, can discharge or balance the overvoltage in main chamber by described air passageways.
Still, liquid pump arranges and is used for opening equilibrated valve in combination with the deexcitation of air pump another preferred expansion scheme.Thus, pressure balance in main chamber and the opening of break-through mouth subsequently can be implemented especially rapidly.Obtain following advantage: cup can be made relatively little, even if also there is not the danger of overflow when liquid flows into strongly.
A kind of preferred improvement project is, pressure port and equilibrated valve are arranged in upper wall or the lid of main chamber or are hydraulically connected with it, can reliably avoid liquid to infiltrate thus.Equilibrated valve can be set directly in the wall of main chamber or by passage and is connected with the pressure balance mouth in the wall of main chamber.
Another preferred expansion scheme is that cup is arranged in the upside of main chamber or on upside.Make liquid from cup fast and fully flow out to main chamber and become easy thus.Also achieve special compact structure form.Especially, cup can stretch in main chamber, is especially so placed in main chamber, makes it not from main chamber outwardly.Cup especially can be integrated in the lid of main chamber.
In the upside that cup especially can be integrated into main chamber or upper wall.Cup or its wall especially can with main chamber or its wall one-body molded.
Another preferred improvement project is, cup and main chamber are spatially separated from one another and be connected to each other by means of passage, such as flexible pipe.This provide higher design flexibility and positional flexibility.
Another preferred expansion scheme is, the liquid surface height sensor of cup has at least two electrodes, and described at least two electrodes can apply voltage, the electric current described in wherein can sensing between at least two electrodes.Reaching of activation level can be determined by the jump type rising of the electric current between electrode or electric conductivity.But, also can use every other suitable liquid surface height sensor, such as float, reed sensor, ultrasonic sensor etc.
Another preferred expansion scheme is, on the bottom that exhaust port is arranged in main chamber or the bottom of main chamber.The substantially emptying completely of main chamber can be realized thus and its compact structure mode can be realized thus.
Housed device especially can be washing drying equipment and liquid pump especially condensate pump.Alternatively, housed device can be such as washing machine, and wherein liquid pump can be such as the lye pump for pumping alkali lye.
Accompanying drawing explanation
Schematically show one embodiment of the present of invention in the accompanying drawings, and describe described embodiment in more detail below:
Described accompanying drawing illustrates the skeleton diagram of the liquid pump in housed device with side view as sectional drawing.
Embodiment
Accompanying drawing illustrates the liquid pump 1 with cup 2 and main chamber 3.Liquid pump 1 arranges in this as condensate pump and is used in washing drying equipment W.Described washing drying equipment W especially can be drier or clothes drier.
Cup has inlet 4, for injecting the liquid of condensed water K form.Condensed water K may have foreign matter---as fine hair and hair and the carrying out washing treatment aid that is dissolved in wherein---and as washing agent residue.Cup 2 bottom it in there is break-through mouth 5, cup 2 is communicated with main chamber 3 by described break-through mouth.Break-through mouth 5 is darker than inlet 4.If break-through mouth 5 is not closed, then the condensed water K being arranged in cup 2 can flow to main chamber 3 by break-through mouth 5.
Main chamber 3 has exhaust port 6 on its sidewall on the height of bottom, for discharging condensed water K.Exhaust port 6 such as can guide to outlet or the clean container of washing drying equipment W.
In addition, main chamber 3 has the pressure port 8 be connected with air pump 7.Main chamber 3 is connected with the on the pressure side D of air pump 7 with hydraulic way.Thus, when air pump 7 activates, main chamber 3 can be placed in overvoltage.When air pump 7 deexcitation, described air pump on the pressure side can air permeable between D at its suction side S and its, makes between main chamber 3 and surrounding atmosphere U, to form unlimited hydraulic channel by air pump 7, can discharge overvoltage by described hydraulic channel.
The valve element of the control liquid level height of spherical float 9 form is provided with in main chamber 3.Float 9 swims in and is arranged on the condensed water K of main chamber 3.Float 9 can be oppressed towards vertical motion direction, such as, by that be made up of multiple bar, microscler, vertical shrouding by means of the simple (not shown) that guides.The liquid level height h of condensed water is depended in the position of float 9.If liquid level height h is positioned at maximum fluid height hmax (dotted line illustrates) below, then break-through mouth 5 opens wide and condensed water K can flow in main chamber 3, and liquid level height h is raised.
At this, condensed water K is not had to flow out from exhaust port 6.This such as can by suitable valve---and such as excess pressure valve realizes.Alternatively or additionally, exhaust port 6 such as can be connected with fluid passage or guide in fluid passage, and described fluid passage extends to the point of maximum fluid more than height hmax, such as, with as a reverse " U " form.
If meet or exceed maximum fluid height hmax (solid line illustrates), then float 9 be placed in break-through mouth 5 edge on and close break-through mouth 5.Break-through mouth 5 has the sealing seat 5a for float 9 on its side towards main chamber 3.Thus, the condensed water K flowed in cup 2 no longer can export in main chamber 3, and the liquid level height h of described main chamber 3 remains essentially on maximum fluid height hmax.Therefore, the condensed water K in cup raises and reaches activation level ha in time.Along with reaching activation level ha, condensed water K reaches two and executes alive electrode 10 and electrode described in short circuit.Recognize reaching of activation level ha thus, activate air pump 7 subsequently.Therefore, electrode 10 is parts (such as except voltage generator) of liquid surface height sensor or this liquid surface height sensor.Electrode 10 can be connected with control gear (not shown), described control gear sensor-lodging and activate air pump 7.Alternatively, electrode 10 can directly be connected with the relay of air pump 7 and activate air pump 7 by short circuit.
Along with the activation of air pump 7, air is forced in main chamber 3, and described main chamber was placed in pressure thus.By means of overvoltage, the condensed water K first in main chamber 3 is such as forced into the clean container of higher height by exhaust port 6, and if liquid level height h drops to below maximum fluid height, then secondly float 9 is yet forced on the edge of break-through mouth 5.On the predetermined time period, air pump 7 is run, main chamber 3 emptying condensed water K substantially within the described time period at this.
Along with the described predetermined time period goes over, again stop or deexcitation air pump 7.Air pump 7 is used as overvoltage release thus, air is discharged into surrounding environment and overvoltage is weak from main chamber 3.Thus, float 9 declines from break-through mouth 5 again and opens described break-through mouth.Like this, the condensed water K accumulated in so far in cup 2 can flow in main chamber 3 subsequently, and process described above can restart.As the additional of air pump 7 or alternative, in order to pressure balance also can use independently equilibrated valve 11.
Certainly, the invention is not restricted to shown embodiment.
