Definitions
- the invention relates to a laundry drying apparatus, comprising a drum housing with a laundry drum accommodated therein and a process air duct fluidly connected to the drum housing, an autonomous heat accumulator being arranged in or on the process air duct.
- the invention also relates to a method for drying laundry in which process air is conducted via an autonomous heat accumulator arranged in or on a process air duct.
- laundry is dried in a tumble-drying appliance designed as a tumble dryer by means of a stream of air guided in a closed process air duct, the air stream being heated before the laundry is pressurized and cooled after the laundry has been pressurized to condense entrained moisture.
- the process air duct contains an air-to-air heat exchanger, a heat storage and a heater, which are passed in this order from the airflow.
- the air flow is started and heated by the heater.
- the admission of the heat exchanger with cooling air is omitted, so that a cooling of the air flow takes place only through the heat storage, which heats up.
- the heat exchanger is exposed to cooling air and takes over the cooling of the air flow;
- the heat storage then no longer serves as a cooler, but as a preheater for the air flow.
- the initially supplied to the dryer heat energy remains the drying process and is not immediately lost through the heat exchanger; however, the savings that can be achieved in this way are small, since only heat from the phase of starting a drying process can be stored.
- the heat accumulator replaces the air-air heat exchanger with a closed process air duct and is the only element in the process air circuit which can absorb heat from it. A reuse of this heat in the drying process is not provided. Rather, after completing a drying process during which it has more or less heated, the heat storage must be cooled and discharged from the stored heat to be available for a new drying process. This is the Heat storage removable from the dryer, and it can be unloaded in a separate discharger.
- washing machines with built-in dryers usually use cooling water to condense the water evaporated from the laundry during a drying cycle ("condensation dryer operation").
- a process air stream is conveyed within the unit by a fan in the circulation, wherein the air is first heated. Thereafter, this air is passed through the laundry drum, where it absorbs moisture from the water moving in this drum by evaporating the water. In the course of this air is passed through a condensation device. There it is usually cooled with cold water from the water inlet to below the dew point temperature. This leads to the condensation of humidity. Thereafter, the air is reheated and passed into the laundry drum. Through the cooling water while the heat of condensation is absorbed from the humidity and pumped together with the condensed water using the sewage pump.
- Sanyo's AWD-AQ1 is a wash dryer available in the Japanese market that uses water from a storage tank to cool the process air and return it to the tank.
- the storage tank is used as a storage for the condensation heat from the drying process.
- a disadvantage of this solution is the high equipment complexity and space requirements and that in such a solution, the water in the storage tank, for example, must be protected from microbial contamination using an ozone generating device or after a predetermined storage time (eg 4 days) must be pumped.
- laundry dryers are known in which the cooling of the process air is effected by a second cooling air flow. Air from the installation room is used to cool the process air. The condensation heat is released here to the air of the installation room.
- the laundry drying device comprising a drum housing with a laundry drum accommodated therein and a process air duct fluidly connected to the drum housing, wherein an autonomous heat storage is arranged in or on the process air duct, a liquid dispenser for applying liquid to the heat storage.
- liquid is applied to the heat accumulator for cooling the heat accumulator.
- the laundry drying apparatus includes a rotatable laundry drum and a process air channel fluidly connected to the laundry drum (i.e., with respect to gas and / or liquid). In or on the process air duct an autonomous heat storage is arranged.
- the process air duct is in fluid communication with the laundry drum on both sides.
- the process air duct and the laundry drum form a process air circuit for processing (drying and reheating) the process air.
- An autonomous heat accumulator is understood to mean a heat accumulator which as such, by virtue of its presence in or on the process air duct, already accomplishes the task and does not first have to make a connection with further functional elements for the function, eg, B. a heat pump.
- the laundry drum is rotatably mounted in a drum housing (lye drum).
- the cached in the heat storage so heat energy can be released between the operating cycles of the washer-dryer slowly by free convection in the device housing to the installation room, z. B. on the device walls.
- Such a laundry drying device does not require cooling water or cooling air to condense the water vaporized from the laundry, is very compact, can be produced easily and inexpensively, and requires very little maintenance.
- the cooling of the heat store can preferably be accelerated by cooling it by means of liquid cooling, preferably water cooling.
- the laundry drying apparatus is preferably equipped with a liquid dispenser for applying liquid to the heat storage.
- Such a liquid dispenser can advantageously be realized in a particularly simple and effective manner if the laundry drying appliance is a laundry dryer and the liquid dispenser comprises a dispenser for feed water to a suds container.
- the amount of water required for washing can be wholly or partially admitted to the heat storage or through the condensation device into the then designed as a tub drum housing.
- the heat accumulator releases its heat energy with the temperature level of the melting temperature to the incoming water.
- energy for heating the wash water can be saved in an immediately following wash program.
- a rinse with warm water also improves the rinsing effect. When spinning warm laundry also lower Schleuderrestfeuchten be achieved than cold laundry. The resulting smaller amount of dried out water leads to a reduction in energy consumption during drying.
- the water conducted through the heat accumulator simultaneously serves to rinse out residues of detergents (foam), fluff and other contaminants that may enter the process airways during washing and drying and thus to regularly clean the process air path.
- the liquid dispenser in particular the Ein Hughesvoriques for feed water, preferably arranged above the heat accumulator.
- the inlet water flushing device can also be used to switch from the operating state "storage of the waste heat in the storage", for example during a drying process, into an operating mode "storage cooling", if the storage capacity of the heat storage is completely filled by waste heat.
- a temperature measurement can also be carried out by direct sensing of the heat storage material, for. B. by a temperature in the heat storage or in the heat storage temperature sensor introduced.
- the liquid dispenser can be triggered.
- the above laundry drying apparatus thus has, inter alia, the advantages that it does not require Kondensationskühlwasser lead, allows a simpler structure than in an air condensation, monitoring the water quality of a water heater is not necessary, and - the scrubber dryer - when performing a wash after drying by Saves the use of hot water energy, improves the washing result and / or the Schleuderrestfeuchte can be improved.
- the heat storage is preferably at least partially designed as latent heat storage. This can save a large amount of heat energy with minimal space requirements.
- a melting temperature of at least one heat storage material between 35 ° C and 60 0 C, in particular between 40 0 C and 50 0 C. Since in a latent heat storage, the temperature is approximately constant equal to the melting temperature, as long as the memory material in the phase transition, in this case is usually between solid and liquid, the temperature of the memory almost does not change, and there is a constant large temperature difference between condensing surface and process air.
- Preferred latent storage materials include, inter alia, paraffins or salts, in particular sodium sulfate (melting point about 32 0 C), sodium thiosulfate (melting point of 48.5 0 C) and / or sodium acetate (melting point about 58 0 C).
- a single latent storage material or a combination of latent storage materials may be used to cover a broader temperature range. The combination may be in the form of a mixture of different materials, or as separate volumes, e.g. B. separate plates.
- the heat storage material is at least partially formed in a plate shape.
- the heat accumulator is preferably arranged in the region of an air intake opening of the air duct (drum outlet).
- the maximum amount of laundry that can be washed during washing has hitherto been divided (for example, halved) for drying and then dried in two successive drying cycles.
- the amount of storage material and thus the heat capacity of the present laundry drying device is preferably such that the heat of fusion is slightly larger than that of the
- Typical amounts of latency storage material may be, for example, in the range between 15 and 20 kg with a heat storage capacity of the order of 200 KJ / kg.
- feed water is passed as liquid via the heat accumulator. This is of particular importance when the method is used in a washer-dryer, since in this way water is preheated for a washing process by means of stored heat from a previous drying process and thus energy from the drying process is utilized in the subsequent washing process.
- feed water is passed via the heat accumulator and on to a drum housing connected to the process air duct.
- the liquid dispenser is triggered.
- a temperature threshold value lying above the melting temperature of the latent heat storage material the liquid dispenser is triggered.
- the liquid dispenser is triggered after reaching or falling below a differential temperature before and after the heat storage. This also serves to prevent an impairment of the method due to exhaustion of the storage capacity of the heat accumulator, alternatively or additionally to the previously described development.
- laundry drying method is described schematically in more detail.
- FIG. 1 shows a sectional side view of a sketch of a laundry drying device.
- FIG. 1 shows a washer-dryer 1 with a drum housing in the form of a tub 2 with a laundry drum 3 rotatable therein.
- a process-air duct 4 is provided on the tub 2 on both sides.
- process air from the washing drum 3 is sucked in by means of a process air blower 7 through an air intake opening 6 provided in the rear wall 5 of the liquor container 2 and first passed through a condensation device 8, where it cools and thereby condenses out in its contained water vapor.
- the condensation water is passed through the lower region 9 of the process recirculated air channels 4 back into the tub 2 and transported from there by means of a drain pump 10 through the drain passage 11 to the outside.
- the condensation water path is indicated by solid arrows.
- the now drier process air is passed through a heating device 12, in which it is heated to typically about 100-120 0 C, before returning to the tub 2 in an upper portion of a sleeve 13 through a Heilausblasö réelle 14 blown.
- the process air flow is indicated by the dashed arrows.
- the condensation device is in the form of an arranged in the process air duct 4 autonomous latent heat accumulator 8, which has a heat storage material in the form of Glauber's salt (which is sodium sulfate) having a melting temperature of 32 0 C.
- the latent heat accumulator 8 is formed as indicated in plate form. So that the 60-80 0 C warm, sucked in by the laundry process air precondensed as little as possible, the heat accumulator 8 is arranged in the region or shortly behind the air intake opening 6.
- the amount of heat storage material is 15-20 kg slightly larger than is typically needed for drying the laundry of a full laundry drum 3.
- the laundry drying apparatus 1 further has an inlet device 15 for feed water for the tub 2 arranged above the heat accumulator 8.
- a water inlet to the flushing device 15 is by means of a controllable by a control device 16 valve 17 either obvious or closed.
- the heat storage 8 is its thermal energy with the temperature level of the melting temperature of the incoming water. In an immediately following wash program so energy can be saved to heat the wash water.
- a rinse with warm water also improves the rinsing effect. When spinning warm laundry also lower Schleuderrestfeuchten be achieved than cold laundry. The resulting smaller amount of dried out water leads to a reduction in energy consumption during drying.
- the guided through the heat accumulator 8 water also serves to rinse residues of detergents (foam), lint and other contaminants that can get into the process airways during washing and drying, and thus to clean the process airway regularly.
- the dispenser 15 is also used for cooling the heat accumulator 8 during a drying cycle.
- a behavior niscle small amount of water of about 0.5 l / min passed from the dispenser 15 on the heat accumulator 8 and pumped out of the drum housing 2.
- This cooling water flow can for example be generated permanently during a drying process, or when the heat storage capacity of the heat storage 8 is completely exhausted by waste heat or threatens to be exhausted.
- a depletion of the heat capacity is detected here by means of temperature sensors 18, 19 inserted in the process air duct 3 in front of and behind the heat accumulator 8 for detecting the air temperature, whose sensor values can be received and evaluated directly or indirectly by the control device 16. Decreases the difference of the
- Temperature sensors 18,19 sensed measured values, and it adapts in particular, this is an indication that the latent storage medium has melted and no further melting energy can be more recorded. Subsequently, the cooling water flow is activated. For this purpose, a temperature difference threshold value is stored in the control device 16, upon reaching or falling below the valve 17 is opened.
- the duration of the water cooling may be stored, for example, as a fixed time interval, which provides an empirically determined sufficient duration for cooling.
- the present invention is not limited to the described embodiment.
- only one temperature sensor may be present in the process air duct, preferably at or behind the outlet of the heat accumulator. It is also possible to switch exclusively between storage of the waste heat in the heat store (for example during drying) and cooling of the heat store; then, in particular, a stronger stream of cooling water is preferred.
- the exhaustion of the heat capacity can be detected by detecting the process air temperature especially at the heat storage output, z. B. by the temperature sensor 19, if the process air temperature rises significantly above the melting temperature of the storage medium 8; This is also an indication that the entire latent storage medium has melted and no further melting energy can be absorbed.
- Another detection option is the detection of the water temperature of the heat storage tank. Rinse water, z. B. by the temperature sensor 18. To complete the water cooling, the valve 17 is closed.
- the latent heat storage can also be used in a separate clothes dryer.
- exhaustion of the heat capacity of the latent heat storage can be detected by direct temperature sensing the latent heat storage material or to the latent heat storage materials.
