Definitions

  • the invention relates to a laundry drying apparatus with a pump and a method for pumping condensate in the laundry dryer.
  • the liquid in the chamber can be pushed out by the overpressure generated by the air pump through the outlet valve, without the liquid itself has to flow through a pump and consequently can not clog or settle. Fluff or long fibers and hair can flow unhindered through the valves.
  • the chamber can be arranged arbitrarily in the household appliance, which allows a compact design of the household appliance.
  • the chamber pump has a high and continuous pumping power.
  • the air pump is mechanically operated and can also be referred to as a compressor.
  • the chamber pump has at least one fill level sensor for sensing a fill level of the liquid in the chamber and at least one control unit coupled to the at least one fill level sensor, wherein the control unit is configured with or after reaching an upper limit value of To switch the pressure of the chamber from suction to pressure and to switch with or after reaching a lower limit of the level of pressure to suction.
  • the delivery process can be carried out once, depending on the amount to be conveyed, in whole or in part, as well as individually repeated periodically or in stages.
  • the respective cover member is bent up in an open position of the associated opening and / or is pivoted away or can be.
  • the cover can thus cover the edge of the associated opening in a simple manner surface.
  • the cover is plate-shaped.
  • the cover may in particular consist of an elastic plastic material.
  • the cover may be fixed or pivotally connected to the chamber.
  • the inlet valve (with the associated inlet opening) is arranged in a bottom of the chamber.
  • the outlet valve may in particular be incorporated in a side wall of the chamber, in particular in a lower half of the side wall.
  • a controllable valve is present and between the air pump and the valve, a cavity is present.
  • the chamber pump is intended for use in a household appliance.
  • foreign matter e.g., in condensate water, caustic or rinse water, etc.
  • an application of the chamber pump is particularly advantageous here.
  • the chamber pump is not limited to large household electrical appliances or household appliances per se. Rather, the range of applications of the chamber pump can extend to the entire field of pumps with comparable performance data.
  • the object is also achieved by a household appliance, wherein the household appliance has at least one chamber pump according to one of the preceding claims.
  • the household appliance can basically be any water-bearing household appliance.
  • the household appliance is a laundry drying device and the chamber pump is a condensate water pump.
  • the chamber pump is particularly advantageous here, since the condensate water typically has hair and long fibers from the laundry to be dried.
  • the target system may e.g. be a condensate collection container or include such.
  • the condensate collector may e.g. a rinse tank for rinsing a device component such as a heat exchanger (e.g., an evaporator in the case of a heat pump dryer) and / or a lint filter.
  • the condensate collection container may additionally or alternatively be designed to be removable from the laundry drying apparatus for emptying the liquid.
  • the target system can also be the unit (s) to be cleaned as such, possibly with the interposition of a filter.
  • the household appliance is a washing device (washing machine, washer-dryer, etc.) or a flushing device (dishwasher, etc.) and the chamber pump is a drain pump. Also in the liquor may be foreign particles that could clog a conventional hydraulic pump.
  • the chamber pump has a trough-shaped housing part and a lid which can be placed on it in a sealing manner. This makes the chamber pump easy to assemble. It is a preferred for simple installation special training that outside the chamber, in particular on the lid, the Air pump, if available, the changeover valve and / or an outlet opening to the target system (container, drain, heat exchanger, sieve, etc.) are attached or arranged.
  • the riser 10 is another, serving as an outlet valve check valve 22 is present, which is a flow of condensate water K allowed out of the chamber 3 in the washing container 11 and prevents backflow into the chamber 3.
  • the chamber pump 2 thus serves for pumping condensate water K from the condensate water reservoir 6 into the washing container 11.
  • the chamber pump 2 can be arranged, for example, at a bottom of the tumble dryer 1, the insertion into the condensate water reservoir 6 allowing a particularly compact design.
  • the chamber 3 can alternately to a suction inlet 12 and a suction side of the air pump 5 (as shown) and be connected to a pressure side or a pressure outlet 13 of the air pump 5.
  • the respective other side or the respective other connection 13, 12 is connected via the switching valve 4 with a ventilation opening 14.
  • the air pump 5 sucks air from the chamber 3 and thus generates there a negative pressure.
  • the negative pressure causes the check valve 8 opens and condensate water K can flow from the condensate water reservoir 6 in the chamber 3 and is sucked.
  • the check valve 22 is held closed by the negative pressure.
  • the check valve 19 is disposed on the side of the second chamber portion 3b and allows flow from the first chamber portion 3a into the second chamber portion 3b, but prevents an opposite return flow (pressure valve).
  • the check valve 19 thus corresponds functionally to the check valve 22 Fig.1 , Since the check valves 8, 19 are plate-shaped, results in a flat sealing contact, which is particularly advantageous for the conveyance of contaminated with hair and lint fluids.
  • the large sealing surface also provides sufficient reserve to handle even heavy soiling. A certain leakage through stuck in the check valves 8, 19 soiling can be absorbed by a reserve power of the air pump 5.
  • the inlet opening 7 and the passage opening 18 each additionally have a large passage cross-section.
  • the switching valve 4 and the air pump 5 are attached to a top 20 of the chamber 3 and connected by respective hoses.
  • the switching valve 4 is further connected via an air line 29 designed as a tube with the chamber 3, more precisely, the first chamber portion 3a.
  • an integrated embodiment can be used, in which the cover of the air pump 5 and the switching valve 4, possibly also the air pump 5 itself, are directly connected to each other and / or made of one piece. This can save at least one hose connection. In particular, all hose connections can be saved, which can reduce installation costs and a susceptibility to errors.
  • a level sensor or level sensor 21 is arranged in or on the first chamber area 3a in order to detect a liquid level or fill level at the limit values P1 or P2.
  • the level sensor 21 is off with the control unit S. Fig.1 coupled.
  • the level sensor 21 may be formed as a single level sensor, in particular with two Sensier einen at P1 or P2, as well as a group of several level sensors.
  • the level sensor 21 may include, for example, electrodes at P1 and P2, include a float, provide a time estimate of the level (virtual sensor), by level measurements outside the chamber 3 or by a motor current monitoring of the air pump to draw a conclusion on the level, etc.
  • the upper liquid level P1 in the first chamber portion 3a is preferably just below the suction of the air pump 5.
  • the chamber 3 can be assembled for easy assembly of a trough-shaped housing part 23 and a cover 24.
  • the trough-shaped housing part 23 comprises the bottom-side inlet opening 7.
  • the partition 17 can be inserted into the trough-shaped housing part 23 or formed integrally therewith.
  • the switching valve 4 and the air pump 5 may be attached to the lid 24 for ease of manufacture and maintenance.
  • the pumping process can be carried out once, completely or partially, and individually repeated periodically or in stages.
  • the liquid is conveyed in portions which correspond at most to the chamber volume between the two limit values or water levels P1 and P2. At lower levels to be delivered (e.g., residual amounts) or otherwise, hysteresis due to sensing may also be circumvented.
  • the chamber pump 2 pumps the liquid or the medium in relatively large portions, and analogously to conventional pumps such as a reciprocating pump or a diaphragm pump with a very large chamber volume.
  • conventional pumps such as a reciprocating pump or a diaphragm pump with a very large chamber volume.
  • relatively long-lasting flows result without interruptions, which significantly reduces a tendency of the foreign bodies in the liquid to settle.
  • a complex gearbox with a high gear ratio would be necessary.
  • the chamber volume of the air pump 5 can thus be very small, and the air pump 5 can run at high speed and thus very good efficiency without a transmission gear.
  • the pumping action in the hydraulic part is realized by the action of the cumulative pressure conditions in the chamber 3 or in the first chamber area 3a.
  • a cavity may be present as an accumulator.
  • the pressure accumulator can be replaced with compressed air (typically to a lesser extent) instead of the chamber also with negative pressure) and through the valve abruptly with great effect on the hydraulic system or the chamber for flushing the clogged / polluted areas apply.
  • the associated additional effort is very low and controllable by the controller especially in the variant with non-reversible pump.
