The operation of drum-type clothes dryer will be described below.
When carrying out high speed by common drum-type clothes dryer when drying, the drum-type clothes dryer turns round under state as shown in Figure 1.
Clothing to be dried 19 is placed in the cylinder 4, and press the button of " high speed processes " in the operation control operation part 31 of clothes dryer.Then, controller 30 sends instruction and motor 10, thermal source 5 and the compressor reducer 17 of driving heat pump elements.When motor 10 rotations, cylinder 4 and heat exchange fan 6 also begin to rotate to produce recycle gas stream and the stream of the cold air shown in arrow Y shown in arrow X.By removing in the clothing 19 of moisture from cylinder 4, the circulated air dry gas becomes and has higher temperature and higher humidity, and is sent to heat exchange fan 6.The circulated air dry gas carries out heat exchange by heat exchange fan 6 and cold air, along with decrease of temperature, and the decline that its temperature and humidity are all a certain amount of, its density increases, and then it is delivered to evaporimeter 15 by circulating line 12.The circulated air dry gas that is removed heat in evaporimeter 15 is dehumidified, and is heated by thermal source 5, and then gets back in the cylinder 4.By said method, owing to being subjected to the net quantity of heat of heat pump elements 15 to 18 and thermal source 5, dries clothing, so clothing is very fast in getting.
Below description is intended to reduce an example that dries cost.
Clothing to be dried 19 is placed in the cylinder 4, and press the button of " energy-conservation process " in the operation control operation part 31 of clothes dryer.Then, controller 30 sends instruction, drives motor 10, thermal source 5 and the compressor reducer 17 of heat pump elements.When motor 10 rotations, cylinder 4 and heat exchange fan 6 also begin to rotate to produce recycle gas stream and the stream of the cold air shown in arrow Y shown in arrow X.The circulated air dry gas becomes the gas that has a little more than atmospheric humidity by the thermal source of heat pump with removing in the clothing 19 of moisture from cylinder 4, and is sent to heat exchange fan 6.Although the circulated air dry gas can carry out heat exchange by heat exchange fan 6 and cold air, however because the temperature difference between recyclegas and the atmosphere is very little, the heat that is exchanged by heat exchange fan 6 seldom, heat exchange fan 6 only plays the effect of fan.Therefore, be used for moisture is removed and the recyclegas that has a little more than atmospheric humidity is sent to evaporimeter 15 by circulating line 12 from clothing 19, the circulated air dry gas that is removed heat in evaporimeter is dehumidified, and delivers to condenser 16 with to be heated, and then gets back in the cylinder.In aforesaid method, because clothing only dries by the heat that heat pump elements produced, the heat of being removed by cold-producing medium in evaporimeter 15 can be got back in the circulated air dry gas in the condenser 16 and use once again.Can suppress the consumption of invalid energy thus and carry out energy-conservation drying thus.
The extent of damage, contraction, the gauffer that the make clothing as far as possible little example that becomes be will be described in below, Fig. 2, Fig. 6 and Fig. 9 consulted as main target.
The clothes-horse 25 that is contained in clothes dryer 26 housings is extracted out forward at the front surface of shell 1, and horizontal sliding bar 25c extracts out to each side from transverse bar 25b.Dry in the air on transverse bar 25b and horizontal sliding bar 25c at the clothing on the clothes hanger 28 19.So, dry switching door 27 and be drawn out of, press " dry process " button of the operation control section of clothes dryer then, then, controller 30 sends compressor reducer 17 and the motor 10 that instruction drives heat pump elements.Motor 10 reverse rotations, 6 rotations of heat exchange fan, but cylinder 4 is owing to the one-way clutch in belt pulley 32 33 remains on halted state, thus the circulated air dry gas stream and the cold air shown in arrow Y that produce shown in arrow X flow.The circulated air dry gas blows the clothing that hits on clothes hanger 28 so that moisture is removed from clothing, and a little more than the temperature before the operation (producing the temperature that is equivalent to 200W to 300W) by heat pump elements 15 to 18 down the humidity of circulated air dry gas begin to increase and will be sent to heat exchange fan 6.Yet heat exchange is not carried out in heat exchange fan 6, owing between recyclegas and cold air, do not have the temperature difference, so heat exchange fan 6 only is used as fan work.Therefore, because the moisture on the clothing, the circulated air dry gas has a little more than the humidity before the operation, and is sent to evaporimeter 15 by circulating line 12.The recyclegas of being removed heat by evaporimeter 15 is dehumidified, and is sent to condenser 16 with to be heated, and recyclegas blows to clothing 19 on the clothes hanger 28 that hangs on the clothes-horse 25 once more to make it air-dry then.In the present embodiment, the clothing 19 of air-dry air-blowing on the clothes hanger 28 that hangs on the clothes-horse 25 of discharging from air-dry gas outlet 27b.Yet the air-dry gas of discharging from air-dry gas outlet 27b blows to the clothing on the clothes hanger that hangs on some thing that is not on the clothes-horse 25 equally.At this moment, air-dry gas outlet 27b can freely change along the circulation of air direction.
That is exactly that the air-dry gas that flows through circulating line 12 is to discharge and blow to institute's airing clothes from air-dry gas outlet 27b.Because air-dry gas blows to clothing 19 from downside, air-dry air-flow also can move along the wind direction of its free convection, quickens air drying process thus.
Cold air shown in arrow Y is blown hit clothing 19, thereby air drying process is quickened.In carrying out dry process, the room that clothes dryer is installed can be used as circulation canal.As mentioned above, because the heat that clothing only produces by heat pump and air-dry, and the heat of being removed by cold-producing medium in evaporimeter 15 gets back to and in the recyclegas in condenser 26 it is heated and is used to air-dry clothing again, and the thermal efficiency is fine.Consult Fig. 8 in addition, when motor 4 reverse rotations,, make cylinder 4 keep motionless thus because be contained in belt pulley 32 idle running that the effect of the one-way clutch 33 in the belt pulley 32 makes head roll band 9, can save the useless energy that makes the cylinder rotation by this structure, and can keep quite.As mentioned above, dry process can make clothing under the as far as possible little situation of its extent of damage, shrinkage, gauffer that clothing is air-dry.
During about the installment state of clothes dryer, the right-hand side of clothes dryer or left-hand side have a wall as shown in Figure 7, a pair of horizontal sliding bar 25c of symmetry on the clothes-horse 25 since the one side can't extend and can't effectively utilize clothes-horse 25.In this case, as Fig. 7 and shown in Figure 10, horizontal sliding bar 25c constitutes the form that an end is long, the other end is short, and horizontal sliding bar 25c can be in right-hand side and the mutual conversion of left-hand side.By like this, be used for wall one side than short slide bar 25c2, long horizontal sliding bar 25c1 is used for opposite side to guarantee the width of clothes-horse 25.
In addition, the rotation of cylinder is air-dry can be carried out simultaneously with dry process, as shown in Figure 4.Here, the clothing 19 of cylinder 4 is air-dry by recyclegas with placing, and drying under switching door 27 situations of closing and will being disposed to the clothing of hanging at the cold air after heat exchange fan 6 carries out heat exchange, can realize simultaneously air-dry by this structure.That is, carry out heat exchange and the part cold air that is heated flows through cold air channel and discharges with the air-dry clothing that is drying in the air by the air-dry gas outlet 50 of auxiliary clothing at heat exchange fan 6.
To describe air dryer below is the example that purpose is operated with the indoor dehumidification, consults Fig. 3.
To dry and switch door 27 extractions, press " indoor dehumidification process " button of the operation control section 31 of clothes dryer then.Then, controller 30 sends compressor reducer 17 and the motor 10 that instruction drives heat pump elements.Motor 10 reverse rotations, heat exchange fan 6 begins rotation; While cylinder 4 is because the one-way clutch 33 in belt pulley 32 remains on halted state, thereby the air-dry air-flow and the cold air shown in arrow Y that produce shown in arrow X flow.As air-dry medium, the circulated air dry gas blows to the indoor of clothes dryer outside by the switching door of extracting out 27 that dries.The circulated air dry gas is removed steam from indoor, and by circulating line 12 the circulated air dry gas is delivered to evaporimeter 15 by heat exchange fan 6.The circulated air dry gas of being removed heats by evaporimeter 15 is dehumidified, and is sent to condenser 16 heating then, the circulated air dry gas by dry switch door 27 from clothes dryer, be discharged to once more indoor, to finish indoor dehumidification.As mentioned above, can dehumidify to indoor by heat pump elements.Because heat pump elements has the moisture removal (5 to 15 liters/day) that can work as with the dehumidifying liquid phase of general room dehumidifier, switch door 27 and enter indoor circulated air dry gas and can make indoor humidity reduce 20% to 30% from drying.Because the indoor drying thing that can not remain when selecting " indoor dehumidification process ", all dehumidifying effects of heat pump can be used for indoor dehumidification.When, for example, when being installed on clothes dryer in the bathroom, can removing from by it and to use other dehumidifier, utilize the dehumidifying effect of clothes dryer can in rainy season, be used for indoor dehumidification.Can eliminate the trouble that produced season through moisture thus and when having a bath because the caused offending sensation of steam.In addition, as shown in Figure 8, when motor 4 reverse rotations, because be contained in belt pulley 32 idle running that the effect of the one-way clutch 33 in the belt pulley 32 makes head roll band 9, make cylinder 4 keep motionless thus, can save the useless energy that makes the cylinder rotation by this structure, and can keep quite.
To describe below when the humidity control of selecting " indoor dehumidification process ".
To dry and switch door 27 extractions, and by humidity sensor 34 induction humidity, continue to make the clothes dryer running to reduce to Parameter H 1 until detected humidity, when detected humidity reached Parameter H 1, running stopped.In addition, running restarts when detected humidity arrives Parameter H 2.Can maintain on the intimate steady state value by the humidity of carrying out repeatedly in this operating room.There, the setting button that setup parameter H1 can be by setting operation control section 31 as shown in figure 11 is to change parameter input controller 30.
To describe below when clothes dryer and be used for making the indoor example that is heated, consult Fig. 3.
To dry and switch door 27 extractions, press " the indoor thermal process that is subjected to " button of the operation control section 31 of clothes dryer then.Then, controller 30 sends instruction driving heat source 5 and motor 10.Motor 10 reverse rotations, and when cylinder 4 remains on halted state owing to the one-way clutch 33 in belt pulley 32,6 rotations of heat exchange fan, thus the air-dry air-flow and the cold air shown in arrow Y that produce shown in arrow X flow.The circulated air dry gas will enter indoor by drying switching door 27 as warm air.As the dry gas of circulated air of cold air by dry switch door 27 open section from indoor suction, and be heated, and in the heat exchange fan, become air-dry hot gas by circulating line 12 by thermal source 5, then by once more from 27 dry switch enter the door indoor.At that time, an indoor part that becomes the circulation canal of gas.Thermal current has 1000 watts the heat of the output energy nearly that is equivalent to the normal domestic use clothes dryer, and hot stream temperature rises to 60 and spends between 80 degree.For example, when being installed on clothes dryer in the bathroom, using clothes dryer and need not to use other warmer, indoorly in such cold season in winter also can become warm.Can eliminate the discomfort sensation after undressing when having a bath thus.
In addition, when selecting " the indoor thermal process that is subjected to ", as shown in Figure 8, when motor 10 reverse rotations, because be contained in belt pulley 32 idle running that the effect of the one-way clutch 33 in the belt pulley 32 makes head roll band 9, make cylinder 4 keep motionless thus, can save the useless energy that makes the cylinder rotation by this structure, and can keep quite.
Temperature control when selecting " the indoor thermal process that is subjected to " will be described below.
To dry and switch door 27 extractions, and by temperature inductor 35 temperature sensors, continue to make the clothes dryer running to reduce to parameter T1 until detected temperature, when detected temperature reached parameter T1, running stopped.In addition, running restarts when detected temperature arrives parameter T2.Can maintain on the intimate steady state value by the temperature of carrying out repeatedly in this operating room.There, the setting button 35a that setup parameter T1 can be by setting operation control operation part 31 as shown in figure 11 is to change parameter input controller 30.
Although in the present invention, the air-dry gas outlet of clothing is arranged at the preceding downside of shell, and the air-dry gas outlet of clothing also can be arranged on upside or other surface.When the air-dry gas outlet of clothing was arranged at side surface, the air-dry gas outlet of clothing was preferably changed, and consideration is installed relation and attached it to the side.Clothing spare is removable although dry in the air, and also can adopt collapsible or Clothoid type when drawing in.
