The air of velveteen is eliminated by turning into the system of low pressure for being depressurized in expansion gear 42 by filter 20
During the heat dump 22 that cryogen flows through, captured sensible heat and latent heat and be dehumidified.Air after being dehumidified by radiator 23 by
Heating.On the other hand, the condensing water droplet for being dehumidified and producing in heat dump 22 falls on water storing unit (not shown).Then, drip
Condensate be discharged to by draining valve 12 outside machine.Act to perform drying steps more than.
In addition, in drying steps, being arranged at the first temperature detecting part 33a and second temperature test section 33b in air channel 19
Detect the temperature of the air flowed in air channel 19.Now, the first temperature detecting part 33a detections flow into the temperature of the air of roller 4
Degree, the temperature for the air that second temperature test section 33b detections are flowed out from roller 4.Then, control unit 35 is according to the first temperature detection
Portion 33a's and second temperature test section 33b exports to detect the degree of drying of the washings in roller 4.Afterwards, control unit 35 exists
Terminate drying steps during aridity as defined in detecting.
On the other hand, in heat pump assembly 41, the gas system of HTHP obtained from being compressed in compressor 25
The heat of cryogen is captured by the air by the radiator 23 in air channel 19, so that gas refrigerant is condensed.Then, in expansion gear
It is depressurized in 42 and the liquid refrigerant as low-temp low-pressure.The liquid refrigerant of low-temp low-pressure is in heat dump 22 from air channel
The air of flowing is captured heat and gasified in 19.Then, the gas refrigerant as low-temp low-pressure, and again return to compressor
25。
Now, the temperature of the refrigerant sprayed from compressor 25 is detected with refrigerant temperature test section 32.Then, control unit
The driving of 35 control air compressor motors 28 so that the temperature of refrigerant maintains defined temperature range (such as 85 DEG C~90
DEG C) in.Thus, make the having stable behavior of compressor 25, and realize the operating of safe and stable heat pump assembly 41.
By the mode, washing action is carried out with not heated washings and action is dried.
Below, the situation that washing action is carried out with the washings after heating, action is dried afterwards is illustrated.
First, when washing operation start, user selects " washing drying in the operating portion 36a of operation display part 36
Program ".Then, clean button 36d to select " warm water cleaning " by operating portion 36a warm water, and set the temperature of washings
(such as 40 DEG C).In addition, the washing carried out using the washings after heating can make dirt be easy to come off to improve cleaning force,
Therefore the washing to water temperature when low is effective.
Then, in cleaning step, cloth consumption test section 37 detects the amount for the washings being put in roller 4.Then,
Control unit 35 opens feed water valve 10 to supply the washings of the amount set according to the amount of washings into tank 1.
Then, control unit 35 detects the temperature of the washings accumulated in tank 1 with water temperature test section 15.Then, control unit
35 are compared the temperature of the washings of setting and the temperature that is detected with water temperature test section 15.Based on as a result, control unit
35 controls wash the energization of water heaters 14 and washings are heated into design temperature (such as 40 DEG C).
Illustrate specific action using Fig. 6.
Fig. 6 is the timing diagram for the action for representing the scrubbing-and-drying unit.
As shown in fig. 6, in cleaning step, first, being acted as water supply, washings are supplied into tank 1.Then, when
Control unit 35 detects to be powered to washing water heater 14 during water level set in advance by water level detecting portion 16.Thus, control
Washings are heated to the temperature of setting by portion 35.In addition, on starting, at the time of the washing energization of water heater 14, to be preferably in
Washing water heater 14 is at least exposed to the state of washings or is submerged in the state of washings.Alternatively, it is also possible in Xiang Shui
The backward washings heater 14 that the washings of the amount set according to the amount of washings have been supplied in groove 1 is powered.
By starting to be powered to washing water heater 14, washings it is heated from environment temperature T1 (such as 20 DEG C) ing and on
Rise.Now, when having supplied the washings of set amount to tank 1, before washings are heated to design temperature, also open
Beginning is washed by stirring action.So, when detecting water level set in advance, by being powered to washing water heater 14
Or start stirring action as early as possible, wash time can be shortened.
Afterwards, washings are heated and make temperature further up.Then, the temperature set when as in " warm water cleaning "
When spending T2 (such as 40 DEG C), control unit 35 stops being powered to washing water heater 14.Then, the stirring for carrying out the stipulated time is moved
Make, and carry out draining action.
In addition, during the draining before middle dehydration is acted, control unit 35 detects heat pump with wind duct temperature test section 34
The temperature of air near the inflow part of device 41.Afterwards, control unit 35 drives pressure fan 21 and detected again with wind duct temperature
The detection of portion 34 flows into the temperature of the air of heat pump assembly 41.In addition, in the driving of pressure fan 21, pressure fan 21 stop when or
Person carries out the detection of air themperature to any time period before dehydration after a stop.
Now, the suction of the inflow heat pump assembly 41 detected after pressure fan 21 is driven with wind duct temperature test section 34
Hot device 22, the air of radiator 23 temperature it is higher than the temperature of air detected before driving pressure fan 21 in the case of,
Control unit 35 is powered to the crankcase heater 30 of compressor 25.Then, heated until the temperature of compressor 25 turns into stream
Untill the temperature level for the air for entering heat pump assembly 41.
That is, for example when environment temperature (T1) is 20 DEG C, in the setting by " warm water cleaning " by washings
It is heated in the case of such as 40 DEG C, the temperature by the washings after heating in tank 1 and roller 4 rises.Now, by sending
The temperature for the air that blower fan 21 is blowed and flowed in air channel 19 rises towards the temperature of temperature of washing water from 20 DEG C.Assuming that will
The temperature of the air flowed in air channel 19 is set in the case of 35 DEG C, is disposed in heat dump 22 and radiator 23 in air channel 19
It is also heated to close to 35 DEG C.The temperature and the temperature of air themperature of the compressor 25 of (including identical) roughly the same with environment temperature
It is 15 DEG C to spend difference D.Therefore, by being powered to crankcase heater 30, compressor 25 is heated to temperature difference D and almost disappeared
Degree.
Equally, in the case where environment temperature (T1) is 10 DEG C, further become big with the temperature difference of the temperature of compressor 25.
In addition, in the case that environment temperature (T1) is 30 DEG C, if setting " warm water cleaning ", the temperature of air is also above compression
The temperature of machine 25.
In addition, in the case where washing dry operating is repeated, due to the dry operating carried out before this, compressor 25
Temperature is the state for having been heated to high temperature sometimes.Therefore, in sky of the temperature higher than inflow heat pump assembly 41 of compressor 25
In the case of the temperature of gas, without the energization to crankcase heater 30.
That is, when the washings after using heating perform cleaning step, the state that the temperature in tank 1 rises
Dehydration in the middle of lower execution.Therefore, because the high speed rotation of roller 4 makes the heated air in tank 1 in air channel 19
Flowing, is heated to the heat dump 22 and radiator 23 being disposed in air channel 19.As a result, in the pipeline 24 of heat pump assembly 41
Refrigerant pressure rise, as described above refrigerant flow into compressor 25.
Therefore, before compressor 25 is driven i.e. in drying steps before dry operating starts, from middle dehydration
During dehydration after to rinse step, the crankcase heater 30 of compressor 25 is powered so that it is heated, until
Untill the temperature of air of the temperature of compressor 25 with flowing into heat pump assembly 41 turns into same degree.For example, in figure 6, therefrom
Between dehydration be powered to rinse step.
Thus, air after being heated in middle dehydration by heated washings is by heat dump 22 and dissipates
, also can be by right before dry operating starts in the case that the hot heating of device 23 to compressor 25 so that flowed into a large amount of refrigerants
Compressor 25 is heated to make the refrigerant in inflow compressor 25 return to outside compressor 25.As a result, can prevent " stagnant
Stay phenomenon ", heat pump assembly 41 is promptly started with optimal state, so that drying property when dry operating starts is carried
It is high.
As described above, the scrubbing-and-drying unit of present embodiment possesses：Roller 4, it is arranged in housing 2；Heat pump assembly 41,

Air is imported in 4.It is also equipped with：Pressure fan 21, it constitutes the air supplying part blown to air channel 19；Wind duct temperature test section 34,
It detects the temperature of the air in air channel 19；Crankcase heater 30, it is heated to compressor 25；Compressor temperature is detected
Portion 31, it detects the temperature of compressor 25；And control unit 35, it is controlled to dry operating.Moreover, control unit 35 is carried out
Following control：Before the startup of compressor 25, the air detected after driving pressure fan 21 with wind duct temperature test section 34
When the temperature of air of the temperature than being detected before pressure fan 21 is driven is high, compressor 25 is entered using crankcase heater 30
Row heating.Thus, in the case of there is temperature difference between the temperature of the air in roller 4 and the temperature of compressor 25, also can
It is enough suitably to keep refrigerant in heat pump assembly 41.As a result, when dry operating starts, heat pump assembly 41 can be made with most
Good state promptly starts, so that drying property is improved.
In addition, in the present embodiment, the temperature of washings when warm water is cleaned is illustrated exemplified by being 40 DEG C, but
It is not limited to this.For example, washings when warm water can certainly be cleaned according to the species of washings, property and purpose
Temperature be set as optimal temperature.In such a situation it is preferred that compressor 25 is heated to crankcase heater 30 optimal
Temperature.
In addition, in the present embodiment, being illustrated with example below：Detected with wind duct temperature test section 34 in wind
In the case of the temperature of the air flowed in road 19, air is blowed into air channel 19 with pressure fan 21, but be not limited to this.Example
As or, in the case of being detected in middle dehydration or dehydration, by the rotation of the high speed of roller 4 come
Detect the temperature of the air flowed in air channel 19.Also, it can also be entered while the high speed rotation of roller 4 with pressure fan 21
Row air-supply and the temperature for detecting the air flowed in air channel 19.
In addition, in the present embodiment, using detected with compressor temperature test section 31 compressor 25 temperature structure as
Example is illustrated, but is not limited to this.Following structure can also be for example set to：Refrigerant is sprayed with installed in from compressor 25
Vicinity pipeline 24 in refrigerant temperature test section 32 on behalf of detection compressor 25 temperature.It is simple thereby, it is possible to realize
Structure.
In addition, in the present embodiment, so that the temperature of air of the temperature of heating compressor 25 with flowing into heat pump assembly 41
Spend to be illustrated exemplified by same degree, but be not limited to this.For example, must not necessarily make the temperature and stream of heating compressor 25
The temperature for entering the air of heat pump assembly 41 is identical.As long as that is, compressor 25 is heated to make in heat pump assembly 41
Refrigerant pressure keep balance temperature arbitrary temperature.
Below, the action of other examples of the scrubbing-and-drying unit of present embodiment is illustrated using Fig. 7.
Fig. 7 is the timing diagram of the action of the other examples for the scrubbing-and-drying unit for representing present embodiment.
As shown in fig. 7, the action of other examples of the scrubbing-and-drying unit of present embodiment and the scrubbing-and-drying unit shown in Fig. 6
The difference of action be in rinse step to heat washings.
That is, as shown in fig. 7, the draining before the dehydration performed after rinse step is close to is acted
In, detected with the temperature of the air of 34 pairs of inflow heat pump assemblies 41 of wind duct temperature test section.Afterwards, the driving of control unit 35 is sent
Blower fan 21 is so that air is in the interior circulation of air channel 19.Then, the air for flowing into heat pump assembly 41 is detected with wind duct temperature test section 34
Temperature after stop pressure fan 21.In addition it is also possible to replace the pressure fan 21 driving and by the high speed of roller 4 rotate come
Detect the temperature of the air flowed in air channel 19.
Now, due to starting to be powered to washing water heater 14, therefore the washings (rinsing supplied in rinse step
Water) it is heated and rises since environment temperature T1 (such as 20 DEG C).Then, set when as the rinse temperature in " warm water cleaning "
During temperature T2 (such as 40 DEG C) set by timing, control unit 35 stops being powered.
Now, the air of the inflow heat pump assembly 41 detected after driving pressure fan 21 with wind duct temperature test section 34
Temperature it is higher than the temperature of air detected before driving pressure fan 21 in the case of, song of the control unit 35 to compressor 25
Axle box heater 30 is powered.Then, heated until the temperature of compressor 25 turns into the temperature for the air for flowing into heat pump assembly 41
Untill degree degree.
That is, in this case, in the setting that warm water is cleaned, being set as in rinse step
Rinsed with warm water.Thus, for example washings are heated in the case of such as 40 DEG C when environment temperature T1 is 20 DEG C, water
The temperature such as air in groove 1 and roller 4 rises.Now, when blowing air by pressure fan 21, flowed in air channel 19
The temperature of dynamic air rises to the temperature close with the temperature of washings from 20 DEG C.Assuming that the sky that will be flowed in air channel 19
The heat dump 22 and radiator 23 that the temperature of gas is set in the case of 35 DEG C, be disposed in air channel 19 are also heated to close to 35
℃.Temperature difference E between the temperature and air themperature of the compressor 25 of (including identical) roughly the same with environment temperature T1 is 15
℃.Therefore, by being powered to crankcase heater 30, compressor 25 is heated to the degree that temperature difference E almost disappears.
Thus, warm water is also being used in rinse step in the same manner as the situation of warm water cleaning is carried out in cleaning step
In the case of, the refrigerant in heat pump assembly 41 also can be suitably kept when dry operating starts.As a result, in dry operating
During beginning, heat pump assembly 41 can be made promptly to start with optimal state, so that drying property is improved.
