Description
The present invention relates to a kind of drying machine and a kind of method run for it, this drying machine comprises hothouse, humidity sensor, control device and process air passage for receiving washing object, one is had for adding heater and an air blast of hot-air in this process air passage, wherein, outside described hothouse, the condensation sensor of at least one optics is furnished with as humidity sensor.
The drying machine of the kind of beginning definition is learnt by JP05-184791.This place describes a kind of drying machine for dry washing material, and this drying machine is configured to waste gas drying machine and discharges via a pipe with the waste gas that moisture loads.In order to prevent forming dew in the tube, i.e. condensate liquid, this pipe is provided with the sensor of the formation for determining dew.If this sensor validation has dew to be formed, then it impels the control device of this drying machine this pipe dry during time interval given in advance.
Learn a kind of drying machine by US2009/0178295A1, in this drying machine, use a steam generation device.This steam generation device comprises a steam generator and a sensor, and this sensor can measure predetermined condition, especially relative humidity or optical beams in the drying machine of work.Also multiple sensor can be set.
In dryer for washings (hereinafter referred to as " drying machine "), make moist washing object dry by means of heat with the process air of drying.Concept " drying machine " (as used in this) represents this drying machine itself, but also represents scrubbing-and-drying unit, in this scrubbing-and-drying unit, also can clean washing object.Scrubbing-and-drying unit is welcome, because be wherein combined with the function of washing machine and the function of dryer for washings in a space-saving manner in a utensil.In addition, scrubbing-and-drying unit has been provided with water tube connector, thus water is not only for cleaning washings, and for processing washing object institute largely.
In drying machine meaningfully, only dried journey is performed when reaching moisture content (" the residue humidity ") of determination of washing object.That is, for further process washing object harmful may be cross and carry out drying and washing object and they for a long time and leave under normal environmental compared with the moisture that comprises in wardrobe and comprise less moisture; That is, they are now very stiff and only poorly can be folded or press.In addition, the dried journey of the reason due to efficiency only should be performed long-time like this, until reach the desired residue humidity of dried washings.In addition carried out dried journey can cause unnecessary energy ezpenditure.Finally, can need again to get wet washing object when ironing subsequently for too dry washings.
Therefore, meaningfully, when reach dried washing object one residue humidity given in advance, dried journey stops.For this reason, the moisture content of washing object usually must be measured by suitable method.
