Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the present invention, with reference to
Present invention is further described in detail with specific implementation mode for attached drawing.
As illustrated in the accompanying drawings from 1 to 3, it present invention is disclosed a kind of fabric drying device, including cabinet 20, is hingedly installed on cabinet 20
Seal cavity is formed after having hermatic door 50, hermatic door 50 to be closed with cabinet 20, the cabinet 20 is interior equipped with installation cavity 201 and dry
The inner surface of dry cavity 202, the drying cavity 202 in cabinet 20 is equipped with heater element, and the top surface of dry cavity 202 is equipped with sliding rail
22, it is hung with hanger 23 on sliding rail 22, installs and is equipped with condenser 30, controller and vacuum pump 40 in cavity 201, condenser and true
Sky pump is connect with controller respectively, and 30 attaching of condenser has refrigerating plant, and vacuum pump 40 is connect by pipeline with condenser 30, cold
Condenser 30 is connected to by pipeline with dry cavity 202.Vacuum pump extracts the air of the drying cavity of cabinet, and dry cavity is made to be in
Lower pressure environment, so that water can boil compared under low temperature condition.Hanger can be slided along sliding rail, and can be slided
It moves to outside hermatic door, fabric to be dried is hung on hanger 23 to convenient for user or is removed from hanger clothing.
Several partition boards 21 are equipped in drying cavity 202 in the cabinet 20, if dry cavity 202 is separated by partition board 21
Dry arid region, the corresponding cabinet top surface in each arid region are both provided with sliding rail, and partition board is equipped with heater element.Pass through setting
Multiple arid regions can dry a variety of clothings simultaneously.
The pressure sensor that pressure is carried for detecting hanger is additionally provided on the sliding rail 22, it can by the pressure sensor
The pressure of hanger carrying is detected, consequently facilitating judging whether the clothing of hanger suspension has been dried.
Be additionally provided with pressure relief valve 41 on the cabinet 20, be connected to inside 41 one end of pressure relief valve and cabinet, the other end with greatly
Gas is connected to, and pressure relief valve 41 can control being switched on or off for its by controlling signal.When the clothing in cabinet has been dried
Bi Hou opens pressure relief valve, the pressure in cabinet can be made to be balanced with extraneous atmospheric pressure, consequently facilitating opening sealing
Door.
The refrigerating plant is compressor or semiconductor chilling plate.Radiating fin, refrigerating plant are additionally provided in condenser
Cold end be connected with fin 31.
The inner air that cavity is dried using vacuum pumped condenser and cabinet makes dry cavity be in subatmospheric
Environment make water that can boil at a lower temperature to reduce the fluidizing point of water.
User will be pushed on fabric carry to hanger 23 to be dried and along sliding rail 22 in the drying cavity inside cabinet 20,
Hermatic door 50 is simultaneously closed off, the heater element after startup power supply switch on 20 interior surface of cabinet and partition board 21 is begun to warm up,
Its maximum heating temperature is no more than 60 degrees Celsius, while condenser 30 starts to freeze, and vacuum pump 40 starts to extract air outward.This
Vacuum pump quantity and installation site in legend is for the ease of understanding that this patent has done simplified partial, in practical applications according to ginseng
The different air extractors of number demand can be collectively constituted by single or multiple vacuum pumps.
As shown in Fig. 4, it can be seen that can also be reduced with the boiling point of pressure reduction water, when cabinet 20 seals cavity pressure
Temperature need to only be more than 46 degrees Celsius of liquid waters and can boil when in the sections 0-10000pa, and the water vapor rate of fluidized state is wanted
Far above the water of non-boiling state, vacuum pump 40 enables to 20 interior sealing chamber air pressure of cabinet to be less than 10000pa.It can send out simultaneously
20 inside face of cabinet and partition board 21 of heat can carry out heat compensation to the fabric being suspended in independent sealed cavity, avoid steam
Change takes away heat and temperature is made to be reduced to water boiling point or less.
In order to avoid steam generates infringement to vacuum pump 40, the gas of extraction can first pass through condenser 30 and carry out at water removal in advance
It manages, 31 surface temperature of several radiating fins inside condenser 30 can be consistently lower than water boiling temperature, and a large amount of steam can be made to exist
30 inside liquefaction of condenser, avoids steam from entering in vacuum pump 40 and generates infringement to it.
Control system built in fabric flash dryer can judge the drying regime of fabric in cabinet, sentence in control system
After disconnected fabric has been completely dried, can control condenser 30, vacuum pump 40 and be installed on partition board 21 or inside cavity face plus
Thermal modules close, and control pressure relief valve 41 unlatching make cabinet door internal and external pressure balance, finally solve locker door allow users to take out
Dry fabric is completed.
Still further aspect, as shown in Fig. 5, present invention further teaches a kind of control method of fabric drying device, the sides
Method includes the following steps：
The pressure of pressure sensor is detected, the pressure of the pressure sensor on each sliding rail is detected.
Show to have hung on hanger and wait doing if pressure value is more than or equal to preset pressure according to the pressure value detected
Dry clothing shows to check dried without suspension clothing or suspension on hanger if pressure value is less than preset pressure
Clothing.If only some sliding rail suspended on clothing to be dried, it suspended on another part sliding rail and dried or do not had
Clothing is hung, then follow-up drying process skips the sliding rail for not hanging clothing or suspended on dried clothes automatically.
When detecting clothing to be dried, heater element starts to generate heat, and heating temperature is less than 60 degrees Celsius, while vacuum pump
Take out the air of the drying cavity in cabinet so that the pressure in drying chamber body is less than 10000pa, and clothing is dried.
In drying process, the collected pressure value of pressure sensor is detected in real time, carries out periodic sampling and is recorded, with
Passing for moisture on fabric to be dried, collected pressure data can taper into, when the pressure value detected is held default
After all not changing in the continuous time, then it may determine that as the fabric no longer dehydration, that is, complete drying.
Terminate drying, close heater element and vacuum pump, open relief valve, pressure solves after being balanced with atmospheric pressure in cabinet
Locker door completes entire drying process.
By above-mentioned drying, heated under environment under low pressure, single drying time can by foreshorten within 1-2 hours 15 minutes with
It is interior, and since drying temperature is relatively low, damage hardly is generated to fabric, while also reducing drying time, improve drying
Efficiency.
It should be noted that these are only the preferred embodiment of the present invention, it is not intended to restrict the invention, although ginseng
According to embodiment, invention is explained in detail, for those skilled in the art, still can be to aforementioned reality
The technical solution recorded in example is applied to modify or equivalent replacement of some of the technical features, but it is all in this hair
Within bright spirit and principle, any modification, equivalent replacement, improvement and so on should be included in protection scope of the present invention
Within.
