Definitions
- the invention relates to a device for loading laundry with an air stream, comprising a substantially closed first channel system for forcibly guiding an air stream loading the laundry, in which first channel system a treatment chamber for receiving the laundry, a blower for driving the air stream, and a heater for Heating the air flow before loading the laundry and a cooler for cooling the air flow after loading the laundry are arranged.
- the invention also relates to a method for supplying laundry with an air stream which is forcibly guided in a first channel system just described.
- the heater and the cooler are components of a heat pump device, and in this heat pump device the cooler forms an evaporator and the heater a condenser for a working fluid circulating in an associated circuit.
- the first duct system in which the air flow is guided, is essentially closed - this means that the air flow circulates essentially without leaks during normal operation, but does not assume a significantly higher pressure than air in the vicinity of the device.
- the air flow is essentially driven by the blower and thus forced through the first duct system; Convection and the like buoyancy effects play a subordinate role at most for driving the air flow.
- the duct system can be connected to the surroundings by opening a flap, in particular in order to discharge part of the air flow heated during operation from the device and to replace it with relatively cool air from the surroundings.
- the treatment room for the laundry is designed as a rotating drum.
- DE 1 410 206 A shows a washing machine in which laundry can not only be washed but also dried.
- the writing shows several alternatives for additional facilities;
- an electric heating device for heating an air stream used for drying laundry and a simple heat exchanger for cooling the heated air stream after loading the laundry can be provided, but the heater and the cooler can also belong to a heat pump device.
- the heat pump device can be designed like the heat pump device disclosed in EP 0 467 188 B1, it can also be a heat pump device which works with Peltier elements to use the thermoelectric effect.
- DE 19 738 735 C2 discloses a device for drying laundry of the type described at the beginning, in which a heat pump device is used which works on the absorber principle.
- a device for drying laundry which in turn corresponds to the type described in the introduction, from an English short extract belonging to JP 08 057 194 A and belonging to JP 08 057 194 A, contains in its first channel system, in addition to a heater and a cooler, both of which A thermoelectrically operable heat pump device includes an additional heat exchanger upstream of the cooler for cooling the air flow discharged from the laundry and an additional heating device downstream of the heater for further heating the air flow before the laundry is acted on for drying laundry which, in addition to a heat pump device with a cooler and heater, has a further heating device and additional heat transport devices such as gravitational heat pipes.
- DE 32 04 718 A1 discloses a drying apparatus for drying laundry by means of an air stream, which has a drying chamber for receiving the laundry, a heating element for heating the air stream and a condensation element for separating moisture from the air stream.
- upward and downward effects are used to drive the airflow, which are caused by heating or cooling of the airflow or part of the airflow.
- a buoyancy effect in the heating element is used in each described configuration of the drying apparatus.
- the condensing element can include a combination of a blower and a valve to support its action; the heating element and the condensing element can be corresponding components of a heat pump system.
- the invention to be described below is based, inter alia, on the object of specifying a device and a method of the type described at the outset, which avoid the disadvantages described above of a channel system which contains many components in succession and which may be multiply folded.
- a device for drying laundry comprising a substantially closed first channel system for forcibly guiding an air stream acting on the laundry, in which first channel system a treatment chamber for receiving the laundry, a blower for driving the air stream, and a heater for Heating the air flow before loading the laundry and a cooler for cooling the air flow after loading the laundry are arranged, in which device, according to the invention, the first duct system outside the treatment chamber and the fan has two branches connected in parallel, which branches from corresponding parts of the air flow in parallel can be flowed through, the heater being arranged in a first branch and the cooler in a second branch of these branches.
- a method for supplying laundry with an air flow, which is forcibly guided in a substantially closed first channel system, in which first channel system a treatment chamber for receiving the laundry, a blower for driving the air stream, and a heater for Heating the air flow before loading the laundry and a cooler for cooling the air flow after loading the laundry are arranged, in which method the air flow outside the treatment chamber and the blower is divided into two parallel parts, a first part of which is the heater and of which the second part flows through the cooler, after which the parts are combined again.
- the invention furthermore advantageously takes advantage of the fact that an air flow absorbs heat the better it is humid, and thus compensates for the disadvantage of having to enter a given amount of heat in only part of the total air flow and having to bring this part to a correspondingly higher temperature. is compensable.
- a great advantage of the invention is that the parallel arrangement and flow through of the heater and the cooler makes a substantially doubled flow cross-section available for the forced air flow and thus a pressure loss when flowing through the arrangement of cooler and heater compared to each described device the state of the art significantly reduced; this reduction is also particularly large in that the cooler and the heater no longer have to be flowed through in succession with the addition of their flow resistances.
- the second branch preferably comprises a separator for separating moisture from the corresponding part of the air flow on the downstream side of the cooler. This separator allows moisture which has been condensed out of the air flow in the cooler to be removed from the air flow and supplied to a suitable collecting container. It is also advantageous to separate the moisture before the parts of the air stream are recombined, since the cooled part of the air stream is reheated by the recombining and condensed moisture could be evaporated again in the process.
- the treatment chamber of the device is preferably rotatable and, in particular, is designed as a drum for receiving the laundry, the inside of the drum being provided with strip-like drivers.
- the items to be washed can be moved and shaken in the air flow acting on them, which is conducive to uniform dehumidification of the items to be washed, while largely avoiding creasing in the items to be washed.
- a particularly preferred embodiment of the device is characterized in that the heater and the cooler belong to a heat pump device, in particular a thermoelectrically operable heat pump device, which heat from the Pumps cooler to the heater.
- the cooler and the heater form critical components that can only be designed and constructed under consideration of difficult boundary conditions, which, due to their interaction in the heat pump device, must expediently be placed relatively close to one another, which, given the spatial conditions in a conventional clothes dryer, leads to design difficulties can lead.
- the cooler and the heater are spatially closely adjacent, because they are arranged on two mutually parallel sides of a more or less flat block-shaped switching block equipped with the required Peltier elements.
- the cooler and the heater are arranged below the treatment chamber; the air flow is led from a rear of the tumble dryer through the treatment chamber to a front, from there into the space below the treatment chamber and from there from the front back to the rear.
- a duct system arranged under the treatment chamber with a thermoelectric heat pump for guiding the air flow must be folded in an S-shape, which requires a particularly long path length for the air flow and thus a relatively high flow resistance.
- the heat pump device in the device particularly preferably comprises at least one thermoelectric switching block with a warm side and a cold side, the cold side being integrated in the cooler and the warm side in the heater.
- the switching block preferably has a multiplicity of Peltier elements arranged next to one another and between two heat-conducting plates, the cold side and the warm side being formed in each case by a heat-conducting plate.
- the cold side and the warm side are preferably each equipped with heat-conducting fins in order to improve the heat transfer to the air flow.
- the cooler is additionally designed as a heat exchanger for an additional cooling medium and is connected to a second channel system for guiding the additional cooling medium.
- Air is particularly provided as an additional cooling medium.
- the heat exchanger for the additional cooling medium is used in particular during a cooling phase provided after the drying of laundry, during which the device, the air flow and the laundry cools will. This is advantageous for avoiding creases in the laundry, since the higher the temperature of the laundry, the easier it is to form creases.
- thermoelectrically operable heat pump device is characterized by two thermoelectric switch blocks and a cooler divided into two halves connected in parallel, the warm side of each switch block being integrated in the heater and the cold side of each switch block being integrated in one of the halves.
- the design offers a particularly low flow resistance for the air flow, has a small space requirement and is very well suited for being equipped with a cooler which, as described above, is additionally designed as a heat exchanger for an additional cooling medium.
- the heat exchanger for an additional cooling medium is also divided into two corresponding halves, each of which is assigned to a corresponding half of the cooler.
- the device according to the invention is designed in particular as a household clothes dryer.
- a preferred development of the invention provides that after the parts have been reunited, the air stream reaches the blower and from the blower to the treatment chamber.
- Preferred configurations of the device according to the invention correspond to preferred configurations of the method according to the invention, and vice versa.
