If foundation passes in and out the change DeltaT of the tube temperature difference and divides: oven dry is dried air through back oven dry air inlet entering urceolus inside in earlier stage, and the temperature of advancing or go out tube is begun to rise by room temperature, and temperature difference T increases gradually, and the clothing at inner core rear portion is dry at first.When difference variation Δ T arrived to a certain degree, the clothing at inner core rear portion was dry, and at this moment, the anterior clothing of inner core also has residual moisture, judged oven dry entering second baking stage.Perhaps, Δ T is the variation of the difference of EAT and leaving air temp, during beginning; The difference of turnover wind-warm syndrome degree is bigger, and with the drying of clothing, temperature raises in the tube; The difference of turnover wind-warm syndrome degree diminishes; Reach setting value, this moment, the clothing at inner core rear portion was dry, judged that oven dry gets into second baking stage.If also have the 3rd or multistage more, then judge according to aforesaid way equally and carry out next baking stage.
If the changes delta G according to drying clothes weight divides: the moisture content of initial cloth is higher, and weight is G
1, adopt first baking stage, drying course, the moisture content of clothing reduces, and the weight step-down is G
2, load weight changes delta G
1=G
1-G
2, Δ G
1During more than or equal to preset value Δ G, judge that oven dry gets into second baking stage, otherwise continue with first baking stage, until Δ G
1>=Δ G.Suppose to be divided into two baking stages, the moisture content of initial cloth is 60%, and gross weight is 8kg, when load weight be changed to gross weight 80% the time, load weight changes delta G
1Be 1.6kg, preset value Δ G is 1.5kg, judges that then oven dry gets into second baking stage.If also have the 3rd or multistage more, then judge according to aforesaid way equally and carry out next baking stage.
If the judgement of baking stage is divided with the difference DELTA P of inlet and outlet wind pressure: the oven dry initial stage; Clothing is because contain moisture content, and volume is less, and the later stage is along with the increase of degree of drying; It is loose that clothing becomes; Volume increases, and can change to the resistance that gets into the wind in the dram, and therefore the pressure of front and back phase turnover wind changes.
First baking stage, the oven dry air gets into inner core from back oven dry air inlet, because of the clothing of Different Weight different to the resistance of wind; When being judged as the clothing of few weight; Clothing is less to the resistance of wind path, blower fan can be with the maximum (top) speed running, and with the rotation speed operation of the blast of satisfying the demand; Can obtain enough big oven dry air quantity, reduce the blower fan input power.And when adopting little air quantity to turn round, can reduce the load of compressor, further reduce the input power of heat pump.
When oven dry got into second baking stage, the oven dry air was dried air inlet in the past and is got into inner core, because wind path length increases, based on the air intake of setting or go out wind pressure, the rotating speed of adjustment blower fan.The mensuration of turnover wind pressure can use the wind pressure testing arrangement to judge; Can judge that also according to the clothes weight under weighing automatically, the predetermined blower fan input current of contrast program carries out blast and judges according to the input current of blower fan under the different clothes weights.
Above-mentioned embodiment is not that design of the present invention and scope are limited, and under the prerequisite that does not break away from design philosophy of the present invention, the various changes and modifications that the professional and technical personnel makes technical scheme of the present invention in this area all belong to protection scope of the present invention.
