Or the temperature of evaporator cold-producing medium, following manner is the temperature of detection heat pump module air intake, if the evaporator system of use
The temperature of cryogen is the most directly replaced.
As shown in Figure 3 and Figure 9, drying starts, deep bead 7 original state for assist air channel to completely enclose low temperature, position
A4, elapsed time t1 are 100s, and when temperature sensor perception enters air themperature T of vaporizer less than T0, T0 is to protect
Card vaporizer inner refrigerant evaporates completely and the temperature of frost does not occur, and motor 8 action, wind inlet channel 31 is entered by deep bead 7
Mouth is closed, position A1.Dry air and be returned directly to heat pump module through low temperature auxiliary air channel.Due to hot blast not through humidity
The heat exchange of medicated clothing, is directly entered heat pump module, the short circuit in this path similar circuit, air circulating-heating at short notice,
Temperature rises.And circulate air not enter cylinder and carry out heat exchange with internal medicated clothing, do not have aqueous vapor to return to heat pump with air
Module, is starting the stage that evaporator evaporation temperature is minimum, and vaporizer will not condense frost.
After elapsed time t2, t2 is usually set to 3～5min, preferably 3min, is divided into following three kinds of situations:

Reaching of a relatively high degree, the air themperature of cylinder air outlet rotates clockwise angle [alpha] 3 also greater than T0, deep bead 7 structure
To position A4, being designated as i=3, low temperature auxiliary air channel is of completely closed, whole air quantity in drying cycle to medicated clothing heating, drying.If
After elapsed time t3, t3 is 30s, if temperature T of temperature sensor perception air intake is less than T2, deep bead 7 turns counterclockwise
Dynamic angle beta, reduces the air capacity entered in cylinder, until temperature T of detection heat pump module air intake is more than T2.
Judge whether deep bead 7 is in A4 position, the most then holding position does not changes, and terminates to drying procedure.If keeping out the wind
Plate 7 is not at A4 position, then adjust deep bead 7 to being in A4 position, and after elapsed time t3, t3 is 30s, compare into
Whether temperature T of wind is more than T2, if T is less than T2, deep bead 7 rotates counterclockwise angle beta, reduces and enters in cylinder
Air capacity, makes evaporator inlet air themperature more than T2.Again after above-mentioned time t2 and above-mentioned steps, do action until
Deep bead is in A4 position, and temperature T of temperature sensor perception heat pump module air intake is more than T2, keeps deep bead 7
Put and do not change, terminate to drying procedure.
Time t1, t2, t3 of above-mentioned setting and temperature T1, T2, T3 set, each type root according to different types
Set also different according to drying the material of medicated clothing, weight and the existing various factors affecting drying efficiency every time, rotational angle α 1,
α 2, the size setting of α 2 and β also change.
The spirit and scope of the present invention are not defined by above-mentioned drying control mode, without departing from design philosophy of the present invention
Under premise, the various changes and modifications that in this area, technical scheme is made by professional and technical personnel, belong to this
Bright protection domain.

There is not the temperature of frost, close drying air channel, control hot blast and be passed through low temperature auxiliary air channel；Temperature T of detection is more than T0,
The most directly dry, proceed to step g；
C, be set time t2 after, if detection temperature T arrive T1, air channel switching mechanism control hot blast enter drying wind
The air quantity in road assists the air quantity in air channel less than entering low temperature, is designated as i=1, enters step d；If temperature T of detection arrives T2,
Air channel switching mechanism controls the air quantity in hot blast entrance drying air channel and assists the air quantity in air channel more than entrance low temperature, is designated as i=2, enters
Step e；If temperature T of detection arrives T3, close low temperature auxiliary air channel, control hot blast and be passed through drying air channel, be designated as i=3,
Enter step f, wherein T3 ＞ T2 ＞ T1 ＞ T0；
D, be set time t3 after, if the temperature of detection is more than T0, then proceed to step g；If the temperature of detection is less than T0,
Then air channel switching mechanism controls to reduce the hot blast air quantity entered in drying air channel, repeats above-mentioned action, until after repeatedly regulation
The temperature of detection, more than T0, proceeds to step g；
E, be set time t3 after, if the temperature of detection is more than T1, then proceed to step g；If the temperature of detection is less than T1,
Then air channel switching mechanism controls to reduce the hot blast air quantity entered in drying air channel, repeats above-mentioned action, until after repeatedly regulation
The temperature of detection, more than T1, proceeds to step g；
F, be set time t3 after, if the temperature of detection is more than T2, then proceed to step g；If the temperature of detection is less than T2,
Then air channel switching mechanism controls to reduce the hot blast air quantity entered in drying air channel, repeats above-mentioned action, until after repeatedly regulation
The temperature of detection, more than T2, proceeds to step g；
G, judge that air channel switching mechanism is whether corresponding when temperature T of detection arrives T3 low temperature is assisted air channel closed state
Under, the most then enter step h；If it is not, then enter step c；
H, judge dry whether terminate, the most then terminate drying procedure；Repeat if it is not, then work on to judge whether dry
Terminate, until terminating drying procedure.
