On the other hand, above-mentioned filter 52 to have the mode with the radius of curvature of the radius of curvature same degree of the inner face of outer barrel 100,120, can form curve form.Be arranged at the position of hot-blast outlet 121 according to filter 52, shape has some differences, but the radius of curvature of outer barrel 100,120 inner face and the radius of curvature of filter 52 have the difference within 10%.Because a part for the rotary wind of cylinder 300,320,340 flows along the inner peripheral surface of outer barrel 100,120, and can, close to filter 52, therefore, make the difference of radius of curvature little, may be effective to filter wash.

With reference to Fig. 6, in the relation of above-mentioned filter 52 between cylinder 300,320,340, around the periphery being positioned at cylinder 300,320,340.Filter 52 will be arranged not interfere the rotation of cylinder certainly in a spaced manner, but for the configuration relation of fore-and-aft direction, can arrange in the mode that will be overlapping with the periphery of above-mentioned cylinder 300,320,340 over half of at least filter 52.In other words, by above-mentioned filter 52 toward on the periphery of above-mentioned cylinder 300,320,340, when projecting with radial direction, the part (PA) of its projection overlapping mode over half should be arranged on the periphery of above-mentioned cylinder 300,320,340.Now, easily carry out to make the rotary wind of cylinder 300,320,340 or deviating from the close of water, thus make above-mentioned rotary wind or deviate from water to be beaten by above-mentioned filter 52 strongly.

In the present embodiment, preferably, above-mentioned filter 52 is supplied by filter assemblies.With reference to Fig. 5 and Fig. 7, filter assemblies 50 is described.Filter assemblies 50 comprises the filter housing 51 installing above-mentioned filter 52.Above-mentioned filter housing 51, as hollow body, comprises the part 51c extended with specific length.And, one end mounting filter 52 of above-mentioned filter housing 51.Above-mentioned filter housing 51 as shown in Figure 5, is arranged to above-mentioned hot-blast outlet 121 inner face with inserting.The outer surface of filter housing 51 is fixed on the inner face of hot-blast outlet 121, can be fastening.For this reason, in the present embodiment, filter housing 51 forms fastener hole 51a, is fixed by screw fastening.Or the inner face of the outer surface of filter housing 51 and hot-blast outlet 121 is fixed with being slidably matched (snug-fit), thus assembles.Above-mentioned filter housing 51 can have equal length with the length of the outstanding prolongation of above-mentioned hot-blast outlet 121.

Although not shown, different from above-mentioned filter assemblies, filter housing forms hollow disk form.Above-mentioned filter is installed on the one side of the filter housing of above-mentioned disk form.The filter assemblies of this form can be fixed on above-mentioned hot-blast outlet 121 with hook combination.The filter assemblies of this disk form in the filter assemblies 50 of Fig. 7, also can be mounting filter in a kind of filter housing 51 bottom outside, remove the form upwards extending the part of formation as hollow body.

On the other hand, in order to more improve the clean result of above-mentioned filter 52, a kind of filter wash portion to above-mentioned filter 52 air supply or water can also be added.When spraying air, spray air by hot blast through the opposite direction of the travel direction of filter 52 when drying.

In the present embodiment, the supply of above-mentioned filter wash portion is as the washings w(cleaning water of water).For this reason, as shown in Figure 2, include branched pipe 11, above-mentioned branched pipe in order to branch in the water supply pipe 10 for preparing to outer barrel 100,120 private water supply out, and to be connected with the feed water inlet 121a of above-mentioned hot-blast outlet 121.

The outer surface of water to above-mentioned filter 52 towards the opposing face of the inner face as outer barrel 100,120 inside carrying out from above-mentioned branched pipe 11 supplying water supplies water.The water of above-mentioned water supply can washing filter 52, can also flow to the inside of outer barrel 100,120.

In order to the washings w washing above-mentioned filter 52 when supplying water to outer barrel 100,120, can together can supply water.From above-mentioned water supply pipe 10 to the place of branched pipe 11 branch, or valve is set at above-mentioned branched pipe 11 within.Therefore, the time point supplying washings w to filter 52 can be regulated.If when not having valve as above, when supplying washings to outer barrel 100,120, often washings w can be supplied to filter 52.

While carrying out the disposable washing filter 52 of washings w supplied water as mentioned above, the velveteen being bonded to filter 52 can be soaked.Under the state identical with it, when cylinder 300,320,340 rotates, its rotary wind or deviate from water and filter 52 collides, and washing filter 52.

On the other hand, washings w evenly can disperse at the outer surface of above-mentioned filter 52 with supplying.For this reason, as shown in Figure 8, washings w feed water inlet can arrange the ejectisome 121b of similar shower nozzle and so on.In the present embodiment, as shown in Figure 9, impingement area 51b is provided with.Washings w when falling and impingement area 51b collide, and to disperse towards periphery, thus be diffused on filter 52.Above-mentioned impingement area 51b in one end of filter housing 51 as above, can form one with filter housing 51.

On the other hand, above-mentioned filter 52 can be metallic filter.Also can be the thread metal wire filter of braided metal (with reference to Figure 10 (a) partly (the top accompanying drawing of Figure 10)).Or, also can be bore multiple hole on a metal plate to make punching filter (with reference to Figure 10 (b) partly (the bottom accompanying drawing of Figure 10)).Punching filter, owing to level and smooth face can be made in the face of filter 52, therefore, has the advantage easily removing velveteen etc.For metal wire filter, have the line filter of the width of mesh of mesh more than 30 due to Kong Tai little, mesh is too many and be not easy to remove velveteen etc.At this, width of mesh decides with the quantity of the mesh of the vertical length of 1 inch.That is, mesh 30 means in the length of 1 inch, has the line filter of the width of mesh of 30 meshes.

The kind of above-mentioned filter 52 considers that the clean result of the rotating speed of cylinder 300,320,340 decides.Such as, decide according to the degree that cylinder 300,320,340 rotating speed just can carry out filter 52 washing at more than 400rpm.

But, ignore the kind of filter 52, when cylinder 300,320,340 rotating speed is more than 1000rpm, also acknowledged filter 52 washing can reach satisfied level.Especially, on filter 52 accumulation velveteen etc. state under, in cylinder 300,320,340, put into the washings soaked, and when performing dehydration with the rotating speed of more than 1000rpm, can the clean result of acknowledged filter 52 outstanding.At this, do not supply the washings w as above of washing filter 52.

In one embodiment of drying device of the present invention, it is inner that filter 52 is exposed to outer barrel 100,120, thus by the rotary wind of cylinder 300,320,340 or deviate from water and automatically wash.Now, washings w is supplied separately by filter wash portion same as described above.

On the other hand, different from above-described embodiment, above-mentioned filter 52 can be arranged at and carry out by the washings be stored in outer barrel 100,120 position cleaned.Such as, different from above-described embodiment, form hot-blast outlet 121 in outer barrel 100,120 bottom, and filter 52 is set at this place.So when the washing stroke in washing process or rinsing stroke, washings carrys out washing filter 52 by washings.Along with cylinder 300,320,340 rotates, the water being stored in outer barrel 100,120 can form current and rise, and close to above-mentioned filter 52, forms the structure of washing.Further, above-mentioned filter 52 is carrying out in washing stroke or rinsing stroke, is arranged in leaching washings in the position of the water stored, thus forms washing.

The above embodiments are washing and dry situation about all possessing.Therefore, above-mentioned water supply pipe 10 via detergent box (not shown), and is connected with outer barrel 100,120.So, when washing or rinsing, supplied water to outer barrel 100,120 by above-mentioned water supply pipe 10, thus perform washing or rinsing.

According to use, after end washing stroke and rinsing stroke, can dehydrating stroke be performed, and perform dry trip after dehydrating stroke terminates.In dry trip, be accumulated to the foreign matters such as the velveteen of filter 52 in the next one of device for clothing processing uses, automatically wash along with through washing stroke, rinsing stroke or dehydrating stroke.In dehydrating stroke situation, spray water droplet in the washings soaked by the through hole of cylinder, and this type of water droplet and filter contacts soak velveteen.When performing dehydrating stroke, the rotary speed due to cylinder is at a high speed, and water droplet as above is close to filter, and therefore, clean result is more outstanding.

Be described as follows with reference to the flow path of Figure 11 to hot blast.Figure 11 illustrates in dry dual-purpose wash mill described above, the flow path of hot blast time dry.Hot blast is that the fan 41 of storage heater 44 by being arranged at drying duct 40 inside and spool 40b inside produces.The air being undertaken by said fans 41 blowing is heated into high temperature due to above-mentioned storage heater 44, and flows.And being carried out the connecting pipe 40a arranged with inserting by hot wind inlet 103 before cleaning-drum, flow in the front to cylinder 300,320,340, and the washings gateway passing through cylinder flows into the inside of cylinder.

Flow into the hot blast in cylinder 300,320,340 and the contact with clothing of soaking, and the state wet with how is by being formed at the through hole 321 of cylinder 300,320,340 wall, discharges outside cylinder 300,320,340.The how wet air in the space be discharged between cylinder 300,320,340 and outer barrel 100,120 by through hole 321 can flow through the space between outer barrel 100,120 and cylinder 300,320,340, and is discharged from outer barrel 100,120 by the hot-blast outlet 121 of the rear quadrate part being positioned at outer barrel layer 120.And the air so being undertaken discharging by hot-blast outlet 121 is sucked by fan 41, thus again blow in drying duct 40, and circulate.

At this, before being discharged by hot-blast outlet 121, the many wet spatial flow of air between outer barrel 100,120 and cylinder 300,320,340, and the moisture contained in air is condensed.In order to effective condensation, heat should be captured from many wet air, thus contact with its ambient air at the outer surface of outer barrel 100,120, by free convection, the outside of this heat to outer barrel 100,120 is released.So, by the free convection of the outer surface of outer barrel 100,120, the how wet air between outer barrel 100,120 and cylinder 300,320,340 loses heat, and its moisture contained just can condensation.

Now, the surface of cold plate 42 and the inner face of outer barrel 100,120 form the water droplet caused by condensation.Above-mentioned cold plate 42, for cooling naturally as above, is not necessary.Although raising condensation rate can be contributed to, even without cold plate 42, also can carry out condensation at the inner face of cleaning-drum 100,120 and reach required condensation rate.Do not have the situation of cold plate 42 can re-start explanation in other following embodiments like this.

The drying device of the present embodiment forms the circulating drying system of hot air circulation.There is no extra condensation pipe, and the space utilization between cylinder 300,320,340 and outer barrel 100,120 is condensation space.

Space temperature between cylinder 300,320,340 and outer barrel 100,120 is lower than cylinder 300,320,340 internal temperature, and outer barrel 100,120 contacts due to the extraneous air ice-cold with outer surface, therefore, there is condensation at outer barrel 100,120 wall or cold plate 42.

Figure 12 is the situation not arranging cold plate 42 in outer barrel 100,120.Outer barrel 100,120 outer surface is by carrying out heat exchange with the free convection of outside.The inner face of the outer barrel 100,120 that how wet the air of discharging from cylinder 300,320,340 be low with the temperature of outer barrel 100,120 contacts, and the moisture that this air contains can carry out condensation.The embodiment of Figure 12 is not except using cold plate 42, identical with the above embodiments.Therefore, additional explanation is omitted.

On the other hand, the above embodiments are inner spaces of outer barrel is the situation of condensation space.That is, the situation of the above embodiments to be outer barrels be condensation part.But, also can have extra condensation part.Such as, utilize condensation pipe as in the past.In the case, its outer surface of above-mentioned condensation part, by the free convection with outside, carries out condensation to the moisture of the how wet air in internal flow.That is, extra additional condensation part and outer barrel can also be had, and the embodiment of condensation occurs due to the cooling naturally of free convection generation in this condensation part.

Further, although the above embodiments are the situations by cooling naturally, cooling water or cold wind etc. is utilized to implement in order to force cooling.Such as, as shown in FIG. 13 and 14, form cooling water injection unit 122 in order to cooling water c.w. can be injected to outer barrel 100,120 inside in outer barrel 100,120.Figure 13 and Figure 14 in the above-described embodiment, forms cooling water injection unit 122 in the outer barrel of the embodiment using cold plate 42, and forms the stream of cooling water c.w. flowing at cold plate 42a.Here, in drying device, cooling water injection unit 122 is formed at outer barrel rear portion 120.Above-mentioned cooling water injection unit 122 is formed under above-mentioned hot-blast outlet.

Above-mentioned cooling water injection unit 122 is the structures of being carried out to the space between outer barrel and cylinder by cooling water c.w. spraying.Or make cooling water carry out flowing along the internal face of above-mentioned outer barrel and supply the structure of cooling water.In the present embodiment, cooling water c.w. supplies between cold plate 42 and outer barrel wall, thus flows along cold plate 42.Above-mentioned cooling water c.w. is discharged by the water discharge outlet being formed at outer barrel bottom.

Cold plate defines cooling water stream in order to make cooling water c.w. flow with zigzag form.Above-mentioned cooling water stream forms groove 42a to make on cold plate.

Figure 14 represents the cross section of the cold plate of the inner face being installed on outer barrel.In order to form cooling water stream, cold plate 42 forming surface is to the groove 42a in the direction of outer barrel wall.That is, by the one side of object outer barrel wall in cold plate 42 to the inner face of outer barrel highlightedly in a zigzag to form groove 42a, thus form stream between outer barrel wall and cold plate 42.The faceted portions of the top and bottom of cold plate 42 is to outer barrel wall buckling, thus the upper and lower in the space of blocking cooling water c.w. flowing.This is the space of flowing to make hot blast not flow into cooling water c.w. as far as possible.Cooling water c.w. intactly directly exposed in hot blast time, because hot blast can make cooling water particle flow into drying duct 40.

Different from Figure 13 and Figure 14 illustrated embodiment, also can not use cold plate.That is, in the embodiment of Figure 13 and Figure 14, can be the structure that cooling water carries out to tub by injection unit 122 injecting.At this, the shape that above-mentioned cooling water injection unit 122 can carry out flowing along outer barrel wall with cooling is made.

On the other hand, filter 52 likely owing to being included in velveteen in hot blast etc. and blocking, when filter 52 blocks, due to hot blast circulation and have some setbacks, thus the low of functions/drying may be caused.Therefore, preferably, be detected the blocking of filter 52, take adequate measures, such as, filter is washed.

With reference to Fig. 2, the mode of the blocking being detected filter 52 is described as follows.The blocking of filter 52 can directly detect, but the flow path of the hot blast comprising filter 52 or the state of circulating path also can be utilized to be detected the blocking of filter 52.If filter 52 blocks, filter 52 becomes a kind of flow path resistance.Therefore, the blocking of filter 52 does not have situation about blocking compared with filter 52, the flowing of hot blast can not be carried out swimmingly.Therefore, the flow regime of hot blast when filter 52 blocks, the flow regime of hot blast when filter 52 blocks is different.Utilize it, just can carry out indirect detection to the blocking of filter.The flow regime of hot blast also can be the temperature, flow, flow velocity etc. of hot blast.

Utilize the flow regime of hot blast to judging that the example that filter 52 blocks is described in detail as follows.

To utilizing hot blast to judge that the blocking of filter is described.Utilize the temperature sensor closely carrying out with storage heater 44 relativity arranging, such as the first temperature sensor 47, judges plugged filter.Hot blast is produced by storage heater 44 and fan 41.The air of the heating of storage heater 44 periphery is blown by fan 41.Blocking due to filter 52 can reduce the air quantity or speed that carry out blowing, and therefore, the temperature of the air of storage heater periphery will rise gradually.That is, when filter 52 blocks, the temperature detected due to above-mentioned first temperature sensor 47 can rise.Therefore, the temperature detected by above-mentioned first temperature sensor 47 just can judge whether filter 52 blocks.That is, during a reference value height that the temperature ratio detected by above-mentioned first temperature sensor 47 is specified, just plugged filter can be judged as.

On the other hand, according to the chocking-up degree of filter 52, the above-mentioned temperature detected also can be different, therefore, the temperature of the chocking-up degree of the filter 52 that detect are set as a reference value.The detected temperatures of plugged filter degree, namely a reference value decides by experiment etc.Such as when utilizing the temperature on drying duct 10 surface, the said temperature a reference value detecting the plugged filter of more than 50% is more than 180 DEG C.

For benchmark when which kind of degree is said reference value block with according to the filter 52 of design, change.Such as, blocking 50% a reference value can be set as, also blocking 75% a reference value can be set as.Experimentally, the situation of blocking 75%, compared with situation about almost not blocking, can confirm that drying time merely add within 10%.In order to can above-mentioned chocking-up degree be considered, also can by multiple for the setting of said reference value.This situation, except considering the blocking of filter, also will consider plugged filter degree, thus performs the requisite measure of filter wash etc.

On the other hand, utilize the temperature sensor relatively far carrying out with storage heater 44 arranging, such as the second temperature sensor 47, judges plugged filter.When filter 52 blocks, owing to carrying out the air quantity of blowing or speed reduces, therefore, the temperature of the air of storage heater 44 periphery will rise gradually.But, the part away from storage heater 44, such as tub, especially outer barrel bottom is the space by hot blast conveying heat, thus hot blast cannot smooth outflow time, temperature can decline.Therefore, when filter 52 blocks, the temperature detected by above-mentioned second temperature sensor 48 is than low when not blocking.Therefore, the temperature utilizing above-mentioned second temperature sensor 48 to detect, judges whether filter 52 blocks.Based on the detected temperatures of the degree of plugged filter, namely a reference value decides by experiment etc.

On the other hand, utilize the whole of the first temperature sensor 47 and the first temperature sensor 48, the blocking of filter is judged.Be described as follows with reference to Figure 15.(a) of Figure 15 partly (left side accompanying drawing) represents the situation that filter does not almost block, and (b) of Figure 15 partly (right side accompanying drawing) represents the situation of plugged filter.In above-mentioned accompanying drawing, the detected temperatures of the first temperature sensor 47 is T1, and the detected temperatures of the second temperature sensor 48 is T2, and temperature difference is between the two △ T.

As mentioned above, when filter 52 blocks, because hot blast cannot flow swimmingly, therefore, the temperature difference △ T between the first temperature sensor 47 and the second temperature sensor 48 can change.Above-mentioned first temperature sensor 47 is compared with the second temperature sensor 48, be positioned at the position closer to above-mentioned storage heater, therefore, even if temperature rises, also because decrease the hot blast being carried out by the heat of storage heater passing in the second temperature sensor 48, thus temperature is reduced.

Temperature difference △ T between first temperature sensor 47 and the second temperature sensor 48 is different according to the degree of plugged filter.When said temperature difference △ T is more than setting value, the blocking of filter can be judged.Consider and storage heater closed in the first design temperature, open in the second design temperature and carry out the problem that controls, detect said temperature difference in above-mentioned setting-up time more than above-mentioned setting value time, can plugged filter be judged.Further, when said temperature difference detects that in above-mentioned setting-up time situation more than above-mentioned setting value is more than set point number, plugged filter can be judged.For judging that the condition identical with it of plugged filter is the situation that provisional blocking to occur due to other reasons to discharge moisture film and the filters such as blocking that similar water causes.

Above-mentioned first temperature sensor 47 and the second temperature sensor 48 can be arranged at the position different from the present embodiment.As long as according to the position that the degree of plugged filter makes temperature different, just can make said temperature sensor 47, temperature sensor 48 is positioned at the position different from the present embodiment.

On the other hand, flow, flow velocity etc. by hot blast are judged that the mode of the blocking of filter is described as follows.Filter 52 blocking can reduce flow or the flow velocity of hot blast.Therefore, detect flow or the flow velocity of hot blast, just can be detected the blocking of filter 52.The flow of hot blast or flow velocity detect by above-mentioned flow sensor 46.That is, the value detected by flow sensor 46 identical with a reference value of reservation or less than a reference value of subscribing time, can be judged as that filter 52 blocks.At this, according to kind or the data processing (data processing) of flow sensor 46, situation large or more identical than a reference value for above-mentioned detection data is judged as filter 52 stopping state.That is, detect data compared with a reference value, judge whether filter 52 blocks, and its comparative approach according to circumstances can be different.Said reference value, for the kind of sensor, decides by performing suitable experiment etc.

On the other hand, different from the above embodiments, utilize the generating mode of hot blast, such as the running status of fan 41 and/or storage heater 44, the blocking of filter is judged.First, with reference to Figure 16, to utilizing the running status of fan 41 to judge that plugged filter is described.

When fan 41 being controlled with pulse width modulation (PWM) control mode, as the running state information of fan, utilize the rotating speed of said fans 41 advantageously, and when fan 41 being controlled with setting speed, in order to rotary fan 41, the utilization electric power be applied on motor can be more favourable.

Figure 16 represents the relation of the static pressure (static pressure) of flow and circulation stream.At this, flow is the volume of time per unit air.And mean that the static pressure of circulation stream is larger, flow path resistance is larger.

The line being masked as C in figure 16 represents the flow-Static compression performance of fan 41 and spool 40b.This obtains by wind tunnel experiment.This together fan 41 is positioned at wind-tunnel with spool 40b, and when applying input electric power to fan 41, the data that the static pressure changing wind-tunnel obtains.

The line being masked as A and B represents that the circulation stream except fan 41 and spool 40b part carries out testing the static pressure based on flow of rear acquisition.B be about the blocking of filter be almost 0% situation, A is about the situation during blocking of a filter part.In order to obtain the line of A and B, remove fan 41 and spool 40b part in the circulation stream of above-mentioned wash mill after, the circulation stream of one end of this removing is exposed in air, thus is maintained atmospheric pressure, and the other end is by below pressure drop to atmospheric pressure.So, obtain above-mentioned atmospheric pressure side and atmospheric pressure with the data on flows of the pressure differential of downside, and show.

The line interface point of above-mentioned C line and A or B is the maximum flow of respective interface point.Certainly, dummy is added to the electric power of fan 41 be the electric power applied when obtaining C is boundary.When the rotation of fan 41 utilizes pulse width modulation (PWM) to control, according to plugged filter, the flow path resistance of above-mentioned circulation stream is increased, therefore line can move to C from B.Flow can reduce from FR2 to FR1, this means that the rotating speed of fan 41 reduces.Therefore, the rotating speed detecting fan 41 just can be detected the chocking-up degree of filter.

If with the blocking of filter independently the rotating speed that fan control is identical, the energy overcoming the flow path resistance increased gradually along with plugged filter degree will be made to increase, and therefore, the input electric power of rotary fan 41 also can increase.So this situation can utilize input electric power as above to detect plugged filter.

Then, with reference to Figure 17, to utilizing the running status of storage heater 44 to judge that plugged filter is described.In order to maintain desired temperature, storage heater 44 controls, for the temperature Tu of the upper limit in setting breaks, to reclose in the temperature of lower limit.In order to the control of storage heater 44, the temperature that the first temperature sensor 47 being positioned at drying duct 40 inside detects can be used.

But if filter 52 blocks, the flowing of hot blast will be made to carry out swimmingly, therefore, the temperature of storage heater 44 periphery can rise.Filter 52 blocking can make the flowing of hot blast smooth and easyly carry out, and makes the temperature of storage heater 44 periphery increase, and therefore, can shorten the time of the temperature Tu arriving the above-mentioned upper limit.So when filter 52 blocks, the number of times that the on/off period of above-mentioned storage heater 44 shortens or repeatedly carries out turning on/off in certain hour △ t increases.Therefore, utilize the on/off period of storage heater 44 and on/off number of times etc. as a reference value, judge the blocking of filter.

Therefore, consider the running status of storage heater 44 as above, judge the blocking of filter 52.Further, along with the chocking-up degree of filter 52, the differences such as above-mentioned cycle or number of times can be made, therefore, also can judge the chocking-up degree of filter 52.Such as according to blocking 50%, blocking 75%, blocking 90% etc. chocking-up degree, above-mentioned cycle or number of times can be different.

The operation of (a) of Figure 17 storage heater when partly (upside accompanying drawing) represents plugged filter 90%, (b) of Figure 17 operation of the storage heater of (downside accompanying drawing) when partly (downside accompanying drawing) represents that filter does not almost block.As shown in above-mentioned accompanying drawing, repeatedly go out storage heater in current upper bound temperature Tu and disconnect, thus temperature reduces, and in lower limit temperature TL, storage heater is connected, thus the phenomenon that temperature rises again.The number of times that storage heater 44 in setting-up time △ t turns on/off, can confirm in the situation of blocking 90% more than unplugged situation.

Be described as follows with reference to the example of Figure 18 and Figure 19 to the control method of the device for clothing processing of the embodiment of the present invention.First, with reference to Figure 18, the control structure figure of the device for clothing processing of the embodiment of the present invention is briefly explained.In controller 900, the first temperature sensor 47, second temperature sensor 48 and flow sensor 46 are electrically connected separately.In controller 900, the motor driven cylinder, storage heater 44, fan 41 and filter wash portion 940 are electrically connected.Further, controller is also connected to input part 910 and efferent 920, and above-mentioned input part 910 can allow user of service operate device for clothing processing, and the duty of device for clothing processing is informed to user of service by above-mentioned input part 920.

With reference to Figure 19, an example of the control method of the device for clothing processing of the embodiment of the present invention is described as follows.

By judging plugged filter (step S5), when being judged as plugged filter, the requisite measures such as filter wash (step S7) will be performed.Preferably, judge plugged filter (step S5), should utilize the flow path resistance produced due to plugged filter and the value changed, that is, the value of the detection hot blast flow path resistance of the temperature, flow etc. of hot blast carries out judging (step S3).Preferably, the judgement of plugged filter should perform (step S1) when judging that device for clothing processing normally works.This is because, under device for clothing processing is in abnormal operating state, is judged as plugged filter, does not block although there is filter, the worry of filter blocks may be judged as.

Be described in detail as follows to each step.First, the step (S1) judging device for clothing processing and whether normally work is described.In order to judge whether filter 52 blocks more exactly, preferably, except filter 52 blocks, when being judged as that device for clothing processing normally carries out work, should judge whether filter blocks.This is because when device for clothing processing non-normal working, likely filter does not block, but can be judged as plugged filter yet.

Whether the normal work of device for clothing processing judges by various method, but is to be judged as that device for clothing processing normally works in such as following situation.The first, when the rotating speed of fan 41 reaches setting speed; The second, through setting-up time after fan 41 operates; 3rd, after dry trip starts, through setting-up time; 4th, after storage heater 44 starts, through setting-up time; 5th, when hot blast reaches design temperature etc.Above-mentioned detection time puts or plugged filter judges that the decision condition of time point also can be used singly or in combination.

Be fan 41 in the parts of flow velocity or a lot of image of flow, therefore judge fan 41 whether after fault, when being judged as that fan does not break down, detect hot blast flow path resistance.Such as, the rotating speed of fan 41 more than setting speed or fan 41 after running through setting-up time, this situation can be considered as fan 41 and normally work.Therefore, this situation can detect hot blast flow path resistance to judge plugged filter.

Dry trip can be considered as through setting-up time after dry trip starts normally to carry out.This is because device for clothing processing is provided with self-measuring device and/or the program that can diagnose the fault of each parts, therefore, when certain component malfunction, fail to interrupt when arriving setting-up time when the carrying out of dry trip.So, now can detect hot blast flow path resistance to judge plugged filter.

Further, when a certain parts of device for clothing processing make a mistake, the work of storage heater 44 normally cannot form arrangement, therefore, utilizes the working time of storage heater 44 to judge some detection time.Such as, to after setting-up time after arriving design temperature from the control temperature of storage heater, detection as above can be performed.Storage heater the first design temperature (such as, 106 DEG C) break, second design temperature lower than the first design temperature (such as, 100 DEG C) middle connection, and storage heater is started in the early stage, after above-mentioned first design temperature of arrival, to after setting-up time, detection as above can be performed.

Then, the step (step S3) detecting hot blast flow path resistance is described.During plugged filter, the resistance of hot blast stream can increase.The resistance of hot blast stream can utilize the state of the hot blast streams such as the temperature of hot blast stream, flow and speed indirectly to detect.Further, utilize the state of the hot blast generating unit of similar fan and storage heater, the on/off period etc. of the rotating speed of such as fan, input electric power or storage heater detects indirectly.The hot blast flow path resistance of above-mentioned multiple kinds can be used singly or in combination, and on the other hand, the hot blast flow path resistance detected is conveyed to controller 900, and above-mentioned controller 900 utilizes the hot blast stream resistance detected, judges whether filter blocks.To plugged filter determination methods, be illustrated above, therefore, will omit its detailed description.

On the other hand, illustrate in the above embodiments and describe the normal work judging device for clothing processing, thus when being judged as that above-mentioned device for clothing processing normally works, detecting hot blast flow path resistance.But the present invention is not limited thereto, but detect hot blast flow path resistance all the time, but only when being judged as that above-mentioned device for clothing processing normally works, whether upper controller etc. can utilize hot blast flow path resistance to block filter to judge.

Then, to when being judged as that filter 52 blocks, the step (step S7) performing requisite measure is described in detail.Can have a variety of to the requisite measure of plugged filter, preferably include user of service's alarm, filter wash function etc.

When being necessary to inform that filter 52 blocks to user of service, export user of service's data with alert.Data with alert energy sense of vision or audio export.The information that sense of vision is blocked by efferent 920 output filter 52 of similar liquid crystal display (LCD) picture and so on.Or, also by sending light to carry out informing of sense of vision.Such as, by being installed on the luminescence of Light-Emitting Diode (LED) lamp of the efferent 920 of device for clothing processing, inform plugged filter to user of service.Audio exports can send certain sound such as buzzing, thus informs user of service.User of service's data with alert as above is different according to the chocking-up degree of filter 52.According to the above-mentioned data degree detected, the degree of plugged filter can be judged, and, also can change the output size of user of service's data with alert as above thus.

On the other hand, receive by above-mentioned efferent 920 and obtain from user of service, as the regulation instruction of the process to blocking.Such as efferent 920 is provided with the device that can input " filter wash " instruction, after this instruction input, controller 900 performs filter wash by the program of specifying.Certainly, this type of user of service's instruction inputting device of filter wash also can not exist, and automatically carries out filter wash in the case.

The method of filter wash has a variety of, such as, can perform following filter wash.The first, drive motors 920 carrys out swing roller, thus is washed filter 52 by the rotary wind of cylinder.Now, when supplying water to outer barrel, after this water is bonded at cylinder surface, by centrifugal force splash, thus there is the effect supplied water to filter 52.The second, start above-mentioned filter wash portion 940, carry out washing filter 52.Two kinds of above-mentioned methods can be used alone or together use.

On the other hand, as the requisite measure performed when judging plugged filter, filter wash preferably performs at reasonable time point.Such as, filter wash can perform in current ongoing dry trip, but the reasonable time point after also terminating at current dry trip performs.This is because when especially utilizing water in filter wash, dry trip that should be preferably current terminates rear execution.

Such as, the situation that the reasonable time point after current dry trip terminates performs filter wash is as follows.After current ongoing dry trip terminates, after the setting-up time of regulation, filter wash can be performed.This is because dry trip terminates, user of service draws out washings needs some times, therefore, performs washing after the setting-up time after dry trip terminates.Further, after dry trip terminates, when door is opened and closed again, can be considered as having drawn out washings, therefore, it be detected, thus perform filter wash.Further, filter wash can perform before following dry trip performs.

On the other hand, under the state that filter 52 blocks, perform dry trip, likely produce the problems of excessive heat of storage heater 44.Therefore, can be arranged to, if be judged as, filter 52 blocks, and when being judged as that filter 52 blocks, then stops current ongoing drying program.Further, current ongoing dry trip also can be made to proceed, and not perform the dry trip of next time.Can when to make not carry out not being activated of dry trip, the work of the user of service input unit relevant to the dry trip of input part 910 etc. is not activated.That is, even if user of service selects above-mentioned user of service's input unit, controller 900 is likely ignored it.

On the other hand, the execution when washing process carries out of above-mentioned filter wash can also be made.When this is due to washing, supply water to outer barrel, even if there is the water being used for filter wash, owing to also can pass through outer barrel, together discharge with washings, thus, the misgivings polluting washings are few.

Referring to Figure 20 and Figure 21, the above-mentioned storage heater 44 of control is described in detail.Preferably, when being judged as plugged filter, also should be different to the control of storage heater 44.Figure 20 is that the heater of filter when not blocking controls pattern, and Figure 21 is heater control pattern when being judged as that heater block.

Once dry trip, controller 900 will open storage heater 44.Along with the unlatching of storage heater, the temperature of device for clothing processing inside can rise rapidly in the early stage.Due in the early stage, the heat energy of storage heater 44 can not be used in the drying to wet clothing too much, and therefore, specific temperature rise is high.Once formally start to carry out to the drying of wet clothing, the heat energy of storage heater 44 can consume in above-mentioned drying, and therefore, said temperature climbing can reduce.

Now, preferably, consider the amount hourly being consumed in the energy of above-mentioned drying, control above-mentioned storage heater 44.This is because the supply of excessive heat energy can cause problems of excessive heat.Due to this reason, can control as repeatedly to turn on/off by above-mentioned storage heater 44.Such as, as shown in Figure 20 and Figure 21, control as repeatedly turning on/off.In Figure 20 and Figure 21, illustrate in the early stage in temperature first transition DT1, also repeatedly turn on/off, but also can be like this.But, when reaching interval DT2 from interval DT1, be likely necessary storage heater 44 to be controlled to the degree that minimizing produces excess phenomenon in the early stage.Due under the state connected at storage heater 44, temperature is in the process of rising, thus, even if disconnect storage heater 44 temperature also can not get started decline.Even if close, temperature also can, after rising a little again, start to decline.

In the interval DT2 that drying is formally carried out, heater cuts out at the temperature (cutting out ﹣ temperature) of the set upper limit, recloses at the temperature (connecting ﹣ temperature) of lower limit.That is, make, after reaching time point (the closing the ﹣ time) closedown of closing ﹣ temperature, repeatedly to control with reclosing at the time point (connecting the ﹣ time) reaching connection ﹣ temperature.

In the early stage in temperature first transition DT1, when reaching DT2, if not due to the problem that excess phenomenon causes, storage heater 44 can be continued to be maintained connection.In order to reduce the excess phenomenon reaching the temperature occurred in the process of interval DT2 as above, in interval DT1, heater also can disconnect at least 1 time.Such as, storage heater 44 can be disconnected reaching the point of the stipulated time before interval DT2.The disconnection times of the heater identical therewith in interval DT1 can be 3 times.In order to reduce excess phenomenon, increasing disconnection times as above perhaps can be favourable, but along with the increase of this number of times, the time reaching interval DT2 likely can increase.Therefore, consider the time reaching interval DT2, above-mentioned disconnection times can be determined.

Control above-mentioned storage heater 44 to rise with making temperature stage at above-mentioned interval DT1, be likely conducive to the problem reducing excess phenomenon.This is as shown in Figure 20 and Figure 21, to set the multiple disconnection ﹣ temperature periodically risen at interval DT1, and can realize by controlling storage heater 44.In order to control storage heater 44 according to disconnection ﹣ temperature and connection ﹣ temperature, as the temperature sensor of detected temperatures, the first temperature sensor 47 of appeal can be utilized.

On the other hand, whether to block according to filter the control of storage heater 44 as above and different.That is, if controller judges plugged filter, then the governing factor by changing above-mentioned storage heater 44 controls, thus changes the control model of heater.The control model of heater can be the on/off temperature of heater, on/off number of times, on/off time, temperature first transition/temperature maintain interval time span etc.This control model described later can be used singly or in combination.

Illustrated in Figure 20, when filter does not block, be controlled to temperature at interval DT1 and rise by 3 stages.Illustrated in Figure 21, when being judged as plugged filter, 8 stages will be controlled to.Due to when plugged filter, hot blast cannot flow swimmingly, thus likely produces overheated problem, thus, the temperature ascent stage of temperature first transition is changed to 8 stages more than 3 stages.According to its chocking-up degree judging plugged filter, which kind of degree is reality be, can say that the quantitative design in above-mentioned stage is different quantity.Such as, due to using blocking 50% as judge plugged filter situation about arranging with using blocking 75% compared with the situation judging plugged filter to arrange, chocking-up degree is more serious, therefore, can increase the stage of temperature rising.

Further, the interval after temperature first transition, that is, at interval DT2, also can be arranged to, and the on/off pattern of storage heater 44 changes along with plugged filter.Simple example has, and in Figure 20 and Figure 21, can be arranged in every case, TUL or TLL changes.Such as, the TUL that can be arranged to Figure 21 is less than the TUL of Figure 20.

In Figure 20 and Figure 21, although be constant in every case at interval DT2, TUL and TLL, need not like that.At interval DT2, also as interval DT1, multiple disconnection-temperature can be set, to make that there is multiple stage.

On the other hand, interval DT1 can be arranged to, and performs to reaching design temperature.That is, in Figure 20 and Figure 21, interval DT1 is performed, until reach TUL.

Figure 22 represents for another embodiment during plugged filter.For Figure 22, compared with Figure 20 of the unplugged state of filter, identical in the quantity of the temperature ascent stage of interval DT1.But, different in the disconnection times of the heater in its each stage.For Figure 20, at each temperature stage of interval DT1, heater only disconnects 2 times, but then disconnects 3 times in fig. 22.

With regard to above-mentioned Figure 21 and Figure 22, the duration (duration time) of interval DT1, compared with the unplugged Figure 20 of filter, longer.

The above embodiments are illustrated the two-purpose type drying washing machine of drying device as washing dual-purpose, as long as but the device with functions/drying just can both be suitable for the present invention.As long as have the device of functions/drying, just all comprise drying device in this manual.
