Definitions
- the invention relates to a washer dryer with Peltier heat pump according to the preamble of patent claim 1
- Such a washer is known for example from DE 69 26 182 U.
- Peltier-Hemenl a marketable Peltier element is known in structure and function.
- Half elements of this Peltier element are formed in a sump or cuboid shape and consist of doped semiconductors as materials
- the semiconductors are in particular bismuth tellu ⁇ d, and there are used a p-type doped semiconductor and an n-type doped semiconductor each a half-element of the semiconductor doped p-type and a half-element of the n-l ⁇ tend doped semiconductors are each connected to one another via a printed circuit board, also referred to as a metal bridge, and to another side, which lies opposite said one side, via a respective further printed circuit board with a further half element or a connection contact for connecting the Peltier Elements connected to an electrical network
- DE 1 410 206 A discloses a washing machine in which laundry is not only washed but also dried.
- the document shows several alternatives, in particular an electric heater for heating an air stream used for drying laundry and a simple heat exchanger for cooling the heated Air flow may be provided after applying the laundry, but the heater and the radiator may also belong to a heat pump.
- the heat pump device may be a heat pump device which uses Peltier elements to utilize the thermoelectric effect.
- An apparatus for drying laundry which, in turn, corresponds to the generic type described in an English abstract extractively belonging to the abstract "Patent Abstracts of Japan" JP 08 057 194 A, contains in its first duct system, in addition to a hot side and a cold side, both belong to a thermoelectrically operable heat pump means, an upstream of the cold side additional heat exchanger for cooling the discharged air from the laundry and a hot side downstream additional heating device for further heating the air flow before the loading of the laundry.
- a Peltier element module in a corresponding heat pump device has a cold side and a hot side. On the cold side air is passed in a tube for cooling and for dispensing moisture. The thus dried air is passed in a tube on the hot side for reheating.
- a filter permeable to air and water vapor to the Peltier elements is arranged in the tube which runs along the hot side of the module (ie is guided along there).
- This filter provides a transport of water effective connection between the space in which the Peltier elements are arranged, and the warm side of the Peltier module, where there is a minimum partial pressure of water vapor at least in the area of the Peltier module. Due to the filter, this minimum partial pressure also adjusts itself to the Peltier elements, and any excess water that might have accumulated there is carried away by the filter to the warm side, thus escaping unwanted moisture from the Peltier elements in the pipe.
- the Peltier elements are now ventilated, from the hot side, and at the same time actively dehumidified.
- the sealing effort in the production of the modules is reduced and the overall quality of the heat pump is improved.
- the filter is preferably impermeable to a liquid, such as water, to preclude ingress of liquid water, at least from the hot side.
- a filter is particularly suitable a filter made of polytetrafluoroethylene, z. B. from expanded polytetrafluoroethylene, as it is offered by the company Gore & Ass. On the market.
- the Peltier elements are preferably arranged in an interior of the Peltier module delimited by walls, and the filter creates an air and water vapor permeable connection from the pipe to the interior (and thus also from the interior to the pipe). Due to the adequate ventilation of the interior of the Peltier Element module prevents pressure fluctuations, and any moisture ingress may evaporate from inside the module due to the water vapor partial pressure gradient.
- FIG. 1 Figure schematically illustrates the construction of a tumble dryer.
- the laundry In the tumble dryer, the laundry is in a laundry drum 10.
- the laundry drum 10 has an outlet 12 and an inlet 14 for air.
- the air from the outlet 12 first passes into a tube 16, into which it is sucked in by means of a pump 18, wherein the tube is led to the cold side (in the picture on the right) of an existing Peltier elements 20 Peltier element module.
- the cold side of the Peltier element module water from the air taken from the laundry in the drum 10 condenses and is collected in a container (not shown).
- the dried air is now passed via the tube 22 into the tube 24, which connects the hot side of the Peltier element module with the inlet 14 of the drum 10. There, the dried air is warmed up, so that it enters the inlet 14 as warm air in order to be able to dry laundry in the drum 10 again.
- the guidance of the air shown in the figure only as a schematic representation of a real leadership, according to which the Peltier elements 20 shown in the figure would have to be successively swept by the air, first at the respective cold side, then at the respective warm side.
- the real guide is to be interpreted as an S-shaped loop passing twice as described above the Peltier elements 20.
- the Peltier element module is sealed to the outside according to the preferred embodiment shown here by walls 26, wherein in the image laterally the tubes 16 and 24 each form the conclusion.
- a filter 28 is provided which is disposed in the tube 24 and creates a connection from the tube interior of the tube 24 to the interior of the Peltier element module.
- the filter 28, shown only schematically herein, is located at a location where it least affects the warming of the air in the tube 24 on the hot side of the Peltier element module and the interior of the Peltier element module with a location in the tube 24, at which there is a minimum partial pressure of water vapor, connects.
- the filter 28 which is made of expanded polytetrafluoroethylene, which is permeable to air and water vapor, but impermeable to liquids, may optionally in the interior of the Peltier element module between the walls 26, for example via leaks to the pipe 16 on the cold side , Liquid entered, evaporate and pass through the filter 28 into the tube 24, and thus out of the interior of the Peltier element module out again.
