As a comparison, the process that additive is fed to described cylinder is described below.Spray into described cylinder by the additive passage 221 that separates with feeding conduit 220 with additive that additive nozzle 351 that steam jet 250 separates will remain in the additive maintaining part 450.Thus, additive can be sprayed into described cylinder and not with steam.

Here, can or be configured to the single injector (not shown) with steam jet 250 and additive nozzle 251 separate construction.Under one-jet situation, steam jetting hole and additive injection hole are respectively formed in the described single injector.That is to say that this type of spray-hole can communicate with steam channel and additive passage respectively.Like this, because by utilizing single injector uperize and additive, so the manufacture order nozzle is easily.For example, be formed on back support member 40, make that production process can be very simple if will be used for one-jet opening (not shown), and can be with steam and additive injection on optimal position.

Though not shown in the accompanying drawings, can omit the pump 601 and the nozzle 251 that are used to supply additive.That is to say, the passage 221 that is used to supply additive can be connected with steam channel 230.In other words, additive is fed to described cylinder is possible to the pressure that is used to supply steam by utilization.

When by steam channel 230 supply steam, can produce acoustic pressure, and by being used to supply the passage 221 absorption additives of additive.Thus, additive is drawn into steam channel 221, and by single injector 250 steam and additive is sprayed into described cylinder.But, at this moment may supply steam to additive maintaining part 450 by passage 221.Therefore, preferably, the check valve (not shown) is arranged on the interpolation road to prevent that steam is supplied to additive maintaining part 450.In addition, owing to be necessary optionally to supply additive, so the closable valve (not shown) of selectivity can be arranged on the additive passage.If close described valve, then only steam is sprayed in the described cylinder.

Thus, because above-mentioned structure, the additional nozzle and the pump that are used for the additive supply just need not.But, in this case, may not can will not have additive to be fed to described cylinder separately with steam.

Therefore, dryer according to the present invention makes additive and steam be supplied to described cylinder dividually, perhaps supplies additive together in supply steam.

More than the structure of single casing 400 with water maintaining part 410 and additive maintaining part 450 is described.But water maintaining part 410 and additive maintaining part 450 are separable and can disassemble from dryer.Equally, water maintaining part 410 and additive maintaining part 450 need not be positioned on the same position.For example, if water maintaining part 410 is positioned on the aforesaid drawer 500, then additive maintaining part 450 can be positioned on the upper surface of dryer or the bottom of front surface.

The foregoing description has been introduced steam and additive supply in described cylinder inside, but the present invention is not limited to this.

For example, in the above-described embodiments, can omit the structure of the steam generator 200 that is used to produce steam.In this case, can provide tiny moisture particulate and replace steam.

Specifically,, then can produce hydraulic pressure, and the water with hydraulic pressure is converted into and will be supplied to the tiny moisture particulate of described cylinder by nozzle 250 if remain on water in the water maintaining part 400 by pump 600 pumpings.Here, the nozzle 250 that is used to supply tiny moisture particulate can have the variform shape with said nozzle.

Can produce tiny moisture particulate by spraying at normal temperatures, and compare with the temperature of steam, the temperature of tiny moisture particulate is so not high.The size of described particulate can be several thousand microns.Therefore, a problem that may exist is that with the vapor phase ratio, tiny moisture particulate may be supplied to the specific region rather than the whole zone of clothing.In addition, it is dark like that tiny moisture particulate may not can penetrate clothing as steam.

For removing the problems referred to above, must the described tiny moisture particulate of heating.That is to say, make that this tiny moisture particulate is similar with steam as far as possible.

In dryer, be provided with feeder, so that hot-air or cold air are fed to aforesaid cylinder.When supplying tiny moisture particulate to described cylinder, preferably, control this feeder operation hot-air is fed to described cylinder.Therefore, heat tiny moisture particulate and also partly form steam.Thus, the size decreases of tiny moisture particulate also has high temperature, thereby moisture can be evenly and penetrated clothing more deeply.The position that is used to spray the nozzle of tiny moisture particulate can be close to the position of the opening portion 42 that the described cylinder of hot-air suction is passed through.

That is to say, will be used for the nozzle 250 that tiny moisture particulate sprays into described cylinder is arranged on back support member 40, and adjacent openings part 42.

Replacedly, nozzle 250 can be on the hot-air supply pipe 44, and can heat tiny moisture particulate in hot-air supply pipe 44, and tiny moisture particulate is fed to described cylinder with hot-air by described opening portion 42.

Simultaneously, can with additive with the steam of above embodiment or tiny moisture particulate dividually or be fed to described cylinder, and the present invention is not limited to this.

As shown in Figure 4, water and additive can be remained in the casing 400 together.Can water and additive together be fed to described cylinder with mixing by pump 600 and nozzle 250.Here, omitted steam generator 400 as shown in Figure 4.If heating is mixed with the water of additive in steam generator 400, then understands and to produce foam owing to surfactant.

Thus, can water and additive is all multi-functional to realize with the clothing that small drops is fed in the described cylinder, for example remove wrinkle and static, make fabric smooth and increase pleasant fragrance.

In addition, be that single casing 400 is filled water and additive easily for the user.

Here, auxiliary additive maintaining part 450 is set up in casing 400, so that the user can put into additive maintaining part 450 with an amount of additive.

As shown in Figure 7, additive maintaining part 450 communicates with water maintaining part 410 by outlet bore portion 451.Here, outlet bore portion 451 is is optionally opened and closed by controller 10.Open and close outlet bore portion 451 and prevented that the additive of crossing volume from mixing with water, optionally is fed to described cylinder with additive with tiny moisture particulate thus.

The film (not shown) can be set in outlet bore portion 451.That is to say, by utilizing in an amount of additive suction water maintaining part 410 that additive in the additive maintaining part 450 and the osmotic pressure between the water in the water maintaining part 410 will only be fed to described cylinder.

Therefore, regardless of the shape of additive, all it is mixed with water in the water maintaining part 410 and it is fed to described cylinder by pump 600 and nozzle 250.

Even because in this example, the temperature of additive and water is not relative higher, additive and water can be fed to described cylinder with aforesaid tiny moisture particulate form thus, they can be supplied with hot-air.

Next, with reference to respective drawings description dryer according to another embodiment of the present invention.

In this embodiment, catch up with that to state embodiment the same, steam and additive can be fed to described cylinder, perhaps tiny moisture particulate, additive and hot-air are fed to described cylinder together.Thus, omitted part same as the previously described embodiments.

In this embodiment, different with the foregoing description, be used to produce the water of steam or tiny moisture particulate by outside resource of water supply supply.That is to say, if necessary, supply water by being positioned at outside hose by controller, rather than supply water by the water maintaining part by the user.

Next, with reference to corresponding accompanying drawing this embodiment is described.

The concrete structure of steam generator 200 at first, is described with reference to Fig. 8.

Steam generator 200 comprises water tank 210, heater 240, level sensor 260 and temperature sensor 270.Water is put into water tank 210, and heater 240 is installed in the water tank 210.The water temperature of the water level of sensing water tank 210 and sensing water tank 210.

Feeding conduit 220 is connected with the predetermined portions of steam generator 200, and feeding conduit 220 is connected with outside resource of water supply such as hose.By feeding conduit 220 water is fed to steam generator.Steam channel 230 connects with another relative part of steam generator 200.One end that nozzle 250 can be installed in steam channel 230 is to improve the efficient of steam jet.Can change between steam generator 200 and the feeding conduit 220 in case of necessity in every way, the coupling part between steam generator 200 and the steam channel 230.According to the kind of fluent material, differently appellation feeding conduit and steam channel, and each passage all can be defined as pipe.

Here, the end of steam channel 230 or nozzle 250 that is to say that steam (vapor) outlet is positioned at the predetermined portions of described cylinder 20, so that steam is sprayed in the cylinder 20.Nozzle 250 can be installed in the front portion or the rear portion of described cylinder, perhaps can be installed on the support member 40 of back.

Feed water valve 281 can be installed on the feeding conduit 220.That is to say that in case of necessity, described controller optionally opens and closes feed water valve.When dryer needs water, this controller opens feed water valve 281, and when dryer did not need water, described controller cut out feed water valve 281.Here, the opening and closing of feed water valve may be with relevant by the water level of 260 sensings of level sensor.That is to say, under the situation of low water level, open feed water valve 281.Under the situation of high water level, close feed water valve 281.

In addition, can on steam channel 230, cut-off equipment be set.Thereby this cut-off equipment can be arranged on the steam generator 200.Described steam generator and steam channel 230 can be included in the steam providing apparatus, and nozzle 250 can be included in the steam providing apparatus.Thus, described cut-off equipment can be included in the described steam providing apparatus.

Described cut-off equipment prevents that the water that overflows of steam providing apparatus is supplied to described cylinder.Here, the water that overflows does not also mean that it is that a spot of water flows to the described cylinder from steam generator.Although this is because be not preferred, also can be discharged in the cylinder 20 with vapor condensation and with the condensed water in the steam channel 230.Thus, the water that overflows can mean that water continues to be supplied to described cylinder from steam providing apparatus, that is to say, continues supply water under uncontrollable situation.

Cut-off equipment can comprise the shutoff valve 282 that is arranged on the steam channel 230.

Can under flow regime, produce the water that overflows.For example, when feed water valve 281 was out of order, water can flow to described cylinder by feed water valve 281 and steam generator 200.Equally, when level sensor 260 was out of order high water level in can not sensing steam generator 200, water can continue to flow to described cylinder by feed water valve 281 and steam generator 200.

Described steam providing apparatus is constructed to described cylinder supply steam, so that a spot of moisture and high temperature can be fed to clothing.That is to say, be necessary in dryer, to be used for the steam of drying clothes.Thus, different with washing machine, dryer can not comprise the bucket that is used for being filled with water, be used to discharge the drainage arrangement and the drainpipe of the water of bucket.If a large amount of water is fed to the described cylinder of dryer, then water only flows into the electric assembly of branch of dryer, can cause electric leakage.In addition, the water that overflows from described cylinder can flow to the dryer outside, causes environmental pollution.The dryer that is used for drying clothes may drench clothing.

But, above-mentioned described cut-off equipment, especially shutoff valve 282 can be avoided these problems.

Can control shutoff valve 282 according to the temperature of steam generator 200.If add hot water and produced steam, then this water has become high-temperature water.But if continue to steam generator supply water, even when adding hot water, the temperature of water still is higher.If the temperature of steam generator has surpassed predetermined value, for example, in the time of 100 ℃, shutoff valve 282 controlled opening, this has just prevented that water is supplied to described cylinder.

Shutoff valve 282 can controlledly communicate with feed water valve 281.For example, can after producing the opening signal of feed water valve 281, controller close shutoff valve 282 with preset time.Here, described preset time can be according to water being fed to steam generator 200 and heating institute's time spent therein and supply steam to described cylinder institute's time spent and be scheduled to.Thus, even under the situation that feed water valve 281 lost efficacy, also can prevent from after preset time water is fed to described cylinder.

Can control shutoff valve 282 and feed water valve 281 is opened basically simultaneously.If shutoff valve 282 is closed during by feed water valve 281 supply water, then from feeding conduit 220 to shutoff valve 282 passage by gastight closing, thereby can not swimmingly water be fed to steam generator 200.

When the amount of the water that is fed to described cylinder by described steam generator is bigger than scheduled volume, can controls shutoff valve 282 and close.Except those situations, shutoff valve 282 can stay open state.

Here, the water yield that can preset by water sensor 283 sensings.This water sensor can be arranged on the feeding conduit 220.This water sensor can be configured to known impeller type transmitter.That is to say, can utilize the rotation number of impeller to come the water yield of sensing by the feeding conduit supply.If water sensor senses excessive water and is supplied to described steam generator, then close shutoff valve 282.

Next, with reference to Fig. 9 and Figure 10 the structure that additive is fed to described cylinder is described.

Fig. 9 shows by feeding conduit 220 steam generator 200 is connected with outside resource of water supply, also shows the structure that is used for additive is fed to described cylinder.

In this embodiment, the drawer type holder (hereinafter becoming drawer) 500 that can move forward and backward independently in the predetermined portions setting of dryer.Casing 400 is installed on the drawer 500.Here, casing 400 is additive maintaining parts, and the additive that remains in the additive maintaining part is supplied to described cylinder.

Casing 400 can be installed in the drawer 500, and drawer 500 installs movably forward and backward shifting to additive passage 220 indirectly and to remove from additive passage 220, rather than casing 400 directly is connected with additive passage 221.This is because the user can put into additive swimmingly.

Drawer 500 can be arranged on the front surface of dryer, that is to say, on the described rack.Especially drawer 500 can be arranged on the control panel 19.

More particularly, support member 520 is installed in the rear portion of control panel.That is to say that support member 520 is parallel with top frame 530 basically.Preferably, drawer guide spare 510 is installed on the support member 520, and top frame 530 guiding and support drawer 500.More preferably, top guide spare 550 is arranged on the drawer guide spare 510.

Here, the top of drawer guide spare 520 and predetermined sidepiece (towards the front surface of dryer) are opening.Drawer 500 moves forward and backward by described opening portion.

In this embodiment, the casing 400 that is used for water is fed to steam generator 200 is dismountable.Here, casing 400 can be configured to can be by the case of custom replaceable, thereby has exempted the trouble that the user directly places additive at every turn.That is to say that the case construction that will have additive is replaceable case formula.If buy this case and it is installed on the dryer, the user just can use described dryer easily.

Kind according to spices can differently change described case.As long as change case, just can satisfy consumers in general's various demands.

Pump 600 can be arranged on the additive passage 221, and produce hydraulic pressure by pump 600.Can additive be sprayed into described cylinder by nozzle 251.

Figure 10 shows casing 400, as shown in figure 10, accommodates various additives in casing 400, for example antistatic additive, spices or their modification.

Casing 400 comprises additive maintaining part 410 and cap 420.Additive is remained in the additive maintaining part 410, and cap 420 covers additive maintaining part 410.

Form osculum 411 on maintaining part 410, as the passage that water is discharged, water is discharged from by this passage, and osculum 411 links to each other with additive passage 211.Water is introduced hole 421 and additive to be introduced hole 422 and is formed on the cap 420.Thus, can introduce hole 421 and additive by water and introduce hole 422 water and additive are introduced, and will not separate from maintaining part 410 by cap 420.

As shown in figure 10, the additive that will be incorporated in the casing 400 by pump 600 and nozzle 251 is fed to described cylinder.Thus, nozzle 251 can be set to separate with the nozzle 250 that is used for uperize.

Additive feeding mechanism according to the present invention comprises that pumping remains on additive in the additive maintaining part 410 with pump that produces hydraulic pressure and the nozzle 251 that is used for the additive of pumping is fed to described cylinder.Certainly, described additive feeding mechanism comprises the passage 221 between pump 600 and the nozzle 251.

Next the process that steam and additive is fed to described cylinder is described.The water that will be used to produce steam by feed water valve 281 and feeding conduit 220 is fed to steam generator 200.

At first, the process that supplies steam to described cylinder is described.The water that will remain in the maintaining part 410 by feed water valve 281 and feeding conduit 220 is fed to steam generator 200.Water in the steam generator 200 is heated so that be converted into steam, by steam channel 230 and steam jet 250 steam is sprayed into described cylinder.Here, shutoff valve 282 prevents that too much water is supplied to described cylinder.

As a comparison, the process that additive is fed to described cylinder is described below.The additive that will remain in the additive maintaining part 450 by additive passage 221 that separates with feeding conduit 220 and the additive nozzle 351 that separates with steam jet 250 sprays into described cylinder.Thus, additive can be sprayed into described cylinder and not with steam.

Thus, water is fed to described steam generator, and the hydraulic pressure that is produced by described pump is fed to described cylinder with additive by external hydraulic.

Here, can or be configured to the single injector (not shown) with steam jet 250 and additive nozzle 251 separate construction.Under one-jet situation, respectively steam jetting hole and additive injection hole are formed in the described single injector.That is to say that this type of spray-hole can communicate with steam channel and additive passage respectively.Like this, because by single injector uperize and additive, so the manufacture order nozzle is very easily.For example, be formed on back support member 40 if will be used for one-jet opening (not shown), then production process can be very simple, and can be with steam and additive injection on optimal position.

Though not shown in the accompanying drawings, can omit the pump 600 and the nozzle 251 that are used to supply additive.That is to say, the passage 221 that is used to supply additive can be connected with steam channel 230.In other words, additive is fed to described cylinder is possible to the pressure that is used to supply steam by use.

When by steam channel 230 supply steam, can produce acoustic pressure, and by being used to supply the passage 221 absorption additives of additive.Thus, additive is drawn into steam channel 221, and by single injector 250 steam and additive is sprayed into described cylinder.But, at this moment may supply steam to additive maintaining part 450 by passage 221.Therefore, preferably, the check valve (not shown) is arranged on the additive passage to prevent that steam is supplied to additive maintaining part 450.In addition, owing to be necessary optionally to supply additive, so the valve (not shown) that alternative can be closed is arranged on the described additive passage.If shut off valve then only sprays into steam in the described cylinder.

Thus, because above-mentioned structure, the additive nozzle and the pump that are used for the additive supply can be dispensable.But, in this case, can not will be not be fed to described cylinder individually with the additive of steam.

Therefore, dryer according to the present invention makes additive and steam be supplied to described cylinder individually, perhaps supplies additive together in supply steam.

More than the structure of single casing 400 with water maintaining part 410 and additive maintaining part 450 is described.But water maintaining part 410 and additive maintaining part 450 are separable and can disassemble from dryer.Equally, water maintaining part 410 and additive maintaining part 450 need not be positioned at on the part.For example, if water maintaining part 410 is positioned on the aforesaid drawer 500, then additive maintaining part 450 can be positioned on the upper surface of dryer or the bottom of front surface.

The foregoing description has been introduced steam and additive has been arranged on described cylinder inside, but the present invention is not limited to this.

For example, can omit the structure of the steam generator 200 that is used to produce steam in the foregoing description.In this case, can provide tiny moisture particulate and replace steam.

Figure 11 schematically shows the control panel 19 on the front surface of the dryer that is formed on Fig. 1.

Controller 110 and control panel 19 can be set on dryer according to the present invention.The operation of controller 110 control dryers comprises the operation of steam providing apparatus, the operation of moisture feeding mechanism, the operation of control panel 19, the operation of additive feeding mechanism, the operation of cut-off equipment and the operation of feeder.Control panel 19 is the interfaces with the user.

Selection portion 111 is arranged on the control panel 19.The user can select various dry runs by using selection portion 111.Described selection portion can be made of dial knob, and perhaps this selection portion comprises some buttons so that the user selects dry run and drying aid option.Described dry run comprises the steam course with vapor recycle, when the user selects steam course, supplies steam to cylinder 120.This vapor recycle can be an option of dry run.In addition, as mentioned above,, tiny moisture particulate and hot-air can be fed to described cylinder when the user selects and the similar circulation time of vapor recycle.

Additive selection portion 112 can be formed on the selection portion 111, so that whether the user selects additive injection in described cylinder.That is, the user can select whether additive to be supplied to cylinder.But,, do not need such additive selection portion 112 according to many embodiment.That is to say, when to described cylinder supply steam or tiny moisture particulate, can supply additive automatically to described cylinder.

Next explanation has the operation of the dryer of above-mentioned structure.Here, additive selection portion 112 is set.

If steam course is selected by user by selecting portion 111, then controller 110 control feed water valves 281 and steam generator 200 are to produce steam.If particularly the user wishes steam is sprayed with additive, then the user can select additive selection portion 112.If the user selects additive selection portion 112, then controller 110 control pumps 600 are to spray into additive on described cylinder.

Because additive and steam are together injected, additive can be sprayed onto on the clothing equably thus, and additive can effectively be brought into play its effect.

Next, with reference to Figure 12 another embodiment is described.In this embodiment, it is different with the foregoing description to be used to prevent that too much water is supplied to the structure of described cylinder.But the structure that is used to supply additive is identical or similar with the structure of the foregoing description.

Be arranged on water tank 292 in the described rack and water is maintained in the water tank 292.By feed water valve 282 water tank 292 is connected with outside resource of water supply such as hose.Level sensor 296 is arranged in the water tank 292 with the sensing water level.Described level sensor comprises common electrode 293, high potential electrode 295 and low position electrode 294.This structure is identical with above-mentioned level in steam generator sensor.

Described water tank has osculum at an upper portion thereof.This round is connected to drainage 297.In this embodiment, exceed water level and locate described osculum, but by described high this water level of potential electrode sensing.

The following describes the process that is used for water is fed to water tank.

Described controller opens feed water valve 282 is to be fed to water in described water tank.If the water level that recognizes in the water tank reaches high water level, then close feed water valve 282.At this moment, owing to may continuing to supply water, fault surpasses described high water level.By described osculum and described drainage the water of glut is discharged dryer, this can not cause leaking yet.For example, these faults may be the fault of feed water valve or the fault of level sensor.

Here, although not shown in the accompanying drawings, drainage can be connected with externally drained pipe.Replacedly, drainage is connected with the drainage of dryer.Described drainage generally includes draining pump and scupper hose.Replacedly, described drainage can be connected with bucket.

Thus, owing to have water tank 292 and drainage 297, so can prevent to supply too much water.Cut-off equipment according to present embodiment comprises water tank 292 and drainage 297.

The water that operation by pump 291 will remain in the water tank is fed to steam generator 200.This pump of described controller function is to be fed to steam generator with water, so that use steam.If pump 291 inoperation, then water can not be supplied to steam generator 200.Thus, even if feed water valve 282 and level sensor 296 are out of order, can prevent that also too much water is supplied to described cylinder.

Be elevated to and preset water level if recognize described level in steam generator, then close pump.The heater of described steam generator is opened adding hot water, and produces steam.The steam that is produced is supplied to described cylinder.

Along with using water in the water tank, water level reduces.Thus, electric current can not be applied between described low position electrode and the described common electrode.In this case, if must supply water, then the controller opens feed water valve 282, and water is fed to water tank 292.

The water flow sensing unit (not shown) can be installed in the water supply hose that makes that water tank is connected with hose, and sensing is fed to the water yield of described water tank.Described water flow sensing unit can be known vane type water flow sensing unit.Can utilize the revolution of impeller to come the water yield of sensing by the water supply hose supply.Preset the water yield if reach, then described controller receives the signal of water flow sensing unit and cuts out feed water valve.If use described water flow sensing unit, then water tank can not comprise level sensor.If the amount of using water flow sensing unit to come the water that sensing is supplied can expect that then operation by pump is fed to the amount of surplus water in the amount of water of steam generator and the water tank.The amount of surplus water is stored in the memory in the water tank, and available amount of storing is controlled described feed water valve.

In this embodiment, can omit the structure of steam generator 200.In this case, can via nozzle 250 tiny moisture particulate be sprayed into described cylinder by the hydraulic pressure that utilizes described pump generation.In this case, described its shape of nozzle may change.

Comprise the possessive construction that tiny moisture particulate and steam is fed to simultaneously described cylinder according to the water supply installation of this embodiment.Certainly, this moment, its shape of nozzle was changeable.

Next, the control method of dryer is described with reference to Figure 13 to 15.

First embodiment of described control method at first, is described with reference to Figure 13.

Described dryer comprises by supply the dry cycle of hot-air with drying clothes to clothing.Here, carry out described dry cycle, surpassed preset time, then finish dry cycle if carry out described dry cycle with the preset time section.

Can control this dry cycle to carry out according to default flowing.Described preset time section is predeterminable in the starting stage of described arid cycle, and described preset time section changes according to the amount of clothing.

The additive that the starting stage that this embodiment is included in described dry cycle will be used for smooth clothing is fed to described cylinder, and is fed to clothing at the additive that the final stage of described dry cycle will be used to give fragrance.

Here, be provided for the additive and the additive that is used to give fragrance of smooth clothing discriminably, to be fed to described cylinder.Yet convenient and production cause is preferably supplied said two devices together for the user.That is to say that described additive comprises composition and the fragrance component that is used for smooth clothing.

In addition, described additive can comprise the composition that is used to remove stink or static.Thus, between in due course, additive is fed to the function that described cylinder can obtain consumer's expectation.

As mentioned above, preferably, additive is fed to described cylinder in the starting stage of dry cycle.That is to say, preferably, additive is fed to described cylinder in the starting stage that is used for smooth drying.If carry out drying, then hot-air is fed to described cylinder.Described hot-air has high temperature, is enough to destroy the fabric of clothing.Dry object overturns in described cylinder or flows with between dry object, or forms friction between dry object and the described cylinder.Because such friction makes clothing to be damaged.

For addressing the above problem, can supply the additive that is used for smooth clothing, and preferably, supply described additive in the starting stage of dry cycle.

As mentioned above, the final stage in dry cycle is fed to described cylinder with described additive.That is to say, described additive is fed to described cylinder to give fragrance to clothing in the final stage of dry cycle.If spices remains on the clothing after dry cycle, then the user can feel uncomfortable.

Here, owing to additive is fed to clothing, then fragrance can be added on the clothing in the starting stage of described dry cycle.Yet along with the carrying out of drying, the effect of this additive will weaken, and preferably, is used for the additive of fragrance in the final stage supply of described dry cycle.

Here, the final stage of described dry cycle is meant the period between before finishing dry cycle 10 to 5 minutes.That is to say, in that period, the additive that is used for spices can be fed to described cylinder.This is that then described spices can not remain on the clothing because if supply spices in after finishing dry cycle 10 minutes.On the contrary, if supply spices in after finishing dry cycle 5 minutes, then can residual too much spices, perhaps because spices former thereby can not drying clothes.

Described dry cycle comprises hot-air is fed to described cylinder and cold air is fed to described cylinder.Here, for the effect of optimization additive supply, can supply additive explicitly with hot-air supply and cold air supply.

Specifically, can be used for the additive supply of smooth clothing in the starting stage of supply hot-air.Afterwards, during the supply cold air, supply the additive that is used for clothing is given fragrance.

Can after the supply additive, supply hot-air.Replacedly, can before or after the supply cold air, carry out the supply of described additive.Examples of such additives supply, hot-air or cold air supply can have the cycle, in this cycle, are used for smooth clothing and the supply that is used for the additive of spices together.

The hot-air supply can comprise heat-flash air supply step and weak hot-air supply step.In heat-flash air supply step with the supply of thermal capacity greatly hot-air, and in weak hot-air supply step with less relatively heating capacity provisioning hot-air.Here, its prerequisite is that the motor that is used to supply hot-air has transformable capacity.

Thus, in the starting stage of described dry cycle, use heat-flash air drying clothing.In the final stage of described dry cycle, use weak hot-air dry clothing.Here, after with weak hot-air dry clothing, use the dry and cooling of cold air.

This changeable capacity of hot-air is preferred for the protection of clothing.Almost finish and the amount of moisture of clothing when very little when drying, supply heat-flash air makes the temperature of clothing sharply rise, and is enough to cause cause thermal damage.

Here, preferably, supply the supply that step is carried out additive explicitly with heat-flash air supply step and weak hot-air.

That is to say, be used for the supply of the additive of smooth clothing, afterwards, in weak hot-air supply step, be used for the supply of the additive of spices in the starting stage of heat-flash air supply step.

Certainly, after the supply additive, can carry out the supply of heat-flash air, perhaps before or after weak hot-air supply step, carry out the supply of additive.The supply of the supply of this additive and heat-flash air or weak hot-air has the cycle, in this cycle, carries out the supply of additive and the supply of heat-flash air or weak hot-air simultaneously.

If the order with heat-flash air supply step, weak hot-air supply step and cold air supply step is carried out dry cycle, then be used for the supply of smooth additive in the starting stage of heat-flash air supply step, and the supply that in cold air supply step, is used for the additive of spices.

But, under any circumstance, can in dry cycle, be used for the supply of the additive of spices basically than after-stage, specifically, carry out finishing between 10 to 5 minutes of dry cycle.This time can change according to the amount of clothing.Along with the increase of clothing, can control the amount of additive.Can control the amount of additive by the time that change is used to supply additive.For example, if the amount of clothing is very big, then can control the time that is used to supply additive longer.
