Description
Technical field
The present invention relates to a kind of method for being used to ask for the final remaining humidity in condenser dryer and one kind to be applied to
The condenser dryer of this method.The invention particularly relates to a kind of method for being used to run condenser dryer and one kind are particularly suitable
In the condenser dryer for performing this method, the condenser dryer has process air passage, roller and control device, process air
Moved in the loop by means of air blower in the process air passage, the roller has the clothing being placed in the roller
Thing object, wherein, the heat exchanger for the condensed water from damp and hot process air is disposed with the process air passage
And at least one humidity sensor.
Background technology
It is related to according to the drying process of the condensation method by means of thermal process air moisture to be evaporated from clothing object
And process air is dried by condensing on the heat exchanger.Here, cold process air is typically logical in the drying process
Cross air blower and be directed through heater.Xeothermic process air is then into the roller as hothouse, the hothouse
Include clothing object to be dried.Here, xeothermic process air receives moisture from clothing object.Then, it is now damp and hot
Process air is further directed into heat exchanger from roller to be dried, such as is directed into air-air-heat exchanger
Or in the evaporator of heat pump.Damp and hot process air is cooled in the heat exchanger or evaporator comprising empty in process
Water in gas is condensed and is aggregated in so-called condensate liquid basin, and the condensate liquid basin is typically in below heat exchanger.
When reaching the liquid level determined, condensed water generally (also referred to as " condensate pump ") is pumped into for intermediate storage by pump
(it is also referred to as " condensate tank ") or is pumped into drainage channel in container.
Drying process is generally divided into three phases, i.e. heating period, primary drying phase and cooling stage.In the heating period
In, process air temperature rise, until reaching previously given temperature value.As temperature increases, process air can be from clothing
More water are received in object, so as to also condense more water on the heat exchanger of cooling is employed for.If reach pre-
First given temperature value, then process air the water of even amount is received typically from the clothing object in roller.That is water
Condensation also keeps constant.The section is referred to as the steady-state process or primary drying phase of drying process.Evaporate the change condensed in other words
Change is stable state, as long as surface water is evaporated from clothing object.If evaporation is finally converted to pore in clothing object fabric
The evaporation of water or capillary water, then need more time and energy to this increase.Therefore evaporation progress ground is slower and thus heat is handed over
Condensation then in parallel operation also carries out slower.Because the discharge reduction that time per unit is condensed, the stage also by
The referred to as unstable state stage.Drying process (also referred to as " drying program ") in the cooling stage, adds as cooling stage terminates
Thermal is typically turned off, and in the cooling stage, is cooled through dry clothing.
The load for passing through clothing object to roller is asked for preferably carrying out in the drying process, so as to make drying
Process matches with load, because the performance of different amounts of clothing object is different.
It is preferred that so perform drying process, so as to get up to the final remaining humidity of the determination through dry clothing object.
This, is typically inferred to moist degree by the measurement to clothing resistance of articles.Therefore, the electrode for being typically different quantity be arranged in it is dry
On diverse location in dry machine.Laundry resistance is measured by direct current or communication method by means of these electrodes.Previously given
Laundry resistance be especially for the heater of process air so-called off value when, now generally terminate drying process.So
And these off value are with the load capacity and initial humidity of clothing object about (being also referred to as the wet wash object from washing machine
" initial residual humidity ") because for example when humidity is identical, the relative humidity for bigger load capacity process air must be
Bigger.In addition it is also contemplated that in the case of big initial humidity, may last much longer until clothing inner
Realize drying.Therefore, usually performed to perform drying process in an improved way for asking for beginning state, that is outstanding
Its load for being used to ask for clothing object and the method and step of initial humidity.Based on such information, can now carry out to closing
The matching of the disconnected limit.So-called windowhood method is also known, and the windowhood method is by multiple measurement parameters such as energy, especially directly
To be currently used for drying the energy altogether consumed, electrical power, temperature and time for being undergone take to it is associated with each other in, so as to
Improve forecast precision.
