N.
The hot air circulation path is specially following each current state; Deep bead 7 is with drying air channel 3 complete closed, and the circulating path of heating fumigators working environment oven dry wind is: breeze fan 26, heat pump air outlet 4, the auxiliary air channel 6 of low temperature, heat pump air inlet 5, evaporimeter 24, condenser 23, breeze fan 26 (consulting Fig. 6).Deep bead 7 is with the auxiliary air channel of low temperature 6 complete closed, and the circulating path of clothes dryer oven dry wind is: clothing, cylinder air outlet 11, line bits filter, air-out air channel 32, heat pump air inlet 5, evaporimeter 24, condenser 23, breeze fan 26 (consulting Fig. 8) in breeze fan 26, heat pump air outlet 4, wind inlet channel 31, cylinder air inlet 12, the cylinder.Deep bead 7 is in the position between the above two, can selectively adjust the ratio that circulating air gets into two air channels, and hot blast is simultaneously in two wind path circulations mobile (consulting Fig. 7).

3, when the temperature T of temperature sensor perceive heat pump module air intake reaches T3; T3＞T2, the interior clothing of cylinder this moment reaches higher relatively degree, and the air themperature of cylinder air outlet is also greater than T0; Deep bead 7 structures clockwise rotate angle [alpha] 3 to the position A4; Be designated as i=3, the auxiliary air channel of low temperature is closed fully, all air quantity in the oven dry circulation to the clothing heating, drying.If behind the elapsed time t3, t3 is 30s, if the temperature T of temperature sensor perception air intake less than T2, deep bead 7 rotates counterclockwise angle beta, reduces to get into the air capacity in the cylinder, up to the temperature T that detects heat pump module air intake greater than T2.
Judge whether deep bead 7 is in the A4 position,, finish to drying procedure if then the holding position does not change.If deep bead 7 is not in the A4 position, then adjust deep bead 7 to being in the A4 position, behind the elapsed time t3; T3 is 30s; Relatively whether the temperature T of air intake greater than T2, if T less than T2, deep bead 7 rotates counterclockwise angle beta; Reduce to get into the air capacity in the cylinder, make the evaporator inlet air themperature greater than T2.After passing through above-mentioned time t2 and above-mentioned steps again, do action is in the A4 position up to deep bead, and the temperature T of temperature sensor perceive heat pump module air intake is greater than T2, keeps deep bead 7 positions not change, and finishes to drying procedure.
The time t1 of above-mentioned setting, t2, t3 and temperature T 1, T2, T3 set according to different machine types; Each type is set also different according to material, weight and the existing various factors that influences drying efficiency of each drying clothes, the size of rotational angle α 1, α 2, α 2 and β is set and equally also changed.
Above-mentioned drying control mode is not that design of the present invention and scope are limited; 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.
