As shown in Figure 6, pressure fan 62 by blower-casting 64, be contained in the blade 65 in the blower-casting 64 and the ion supply fan electromotor 66 of blade 65 rotation constituted.Blower-casting 64 becomes monomer by resin-shaped, and as shown in Figure 5, the round entrance 64a with cross-shape frame opens by upper surface, and as shown in Figure 6, cylindrical outlet 64b is formed on rear side.As shown in Figure 6, check-valves 67 is installed in outlet 64b place, thereby prevents that air flow from getting back in the blower-casting 64.In addition, filter 68 is arranged on inlet 64a place, thus the cover framework part.
Ion supply fan electromotor 66 is directly connected on the blade 65, and makes blade 65 rotations by direct driving.The opening (not shown) of pressure fan 62 by the heat transmission that passes housing 1 and form etc. sucks air, and inhaled air is delivered to ajutage 63.
Shown in Figure 4 and 5, the cylindrical ion that is used to remove air is introduced the upper left quarter that hole 22a passes the peripheral surface at tank 20 backs 22 and is formed.There is such risk: if when the internal pressure of tank 20 is high, water is supplied to cylinder 34, then water can reflux, therefore, in order to prevent this risk, ion is introduced hole 22a form and air is leaked out from tank 20 so that obtain lower tank 20 internal pressures.
Ajutage 63 is a kind ofly to form, have the structure and the part by the upper and lower is fitted to each other and makes up that are divided into the upper and lower by animi resin.As shown in Figure 6, be formed on an end of ajutage 63 towards preceding inlet opening 63a.The inlet opening 63a of ajutage 63 is connected to the outlet 64b of blower-casting 64.As shown in Figure 5, the main part of ajutage 63 has the crooked gradually flat shape of extending from right to left on tank 20 backs 22.As shown in Figure 6, prone outflow opening 63b is formed on the other end of ajutage 63.The outflow opening 63b of ajutage 63 away from and introduce hole 22a towards the ion on tank 20 tops and be provided with.Here, in the normal state, the distance L that the ion on the outflow opening 63b of ajutage 63 and tank 20 tops is introduced between the 22a of hole is set to about 17mm, thereby this value is to allow cation that ion generating device 61 produces and anion to be sent to tank 20 efficiently to avoid introducing hole 22a because the vibration of tank 20 is flowing out opening 63b when moving up and ion is introduced the beeline that generation is collided between the 22a of hole when ion.The internal diameter φ 1 of the outflow opening 63b of ajutage 63 is set to about 29mm, and the internal diameter φ 2 of the ion on tank 20 tops introducing hole 22a is set to about 23mm.Flow out the internal diameter φ 2 of the internal diameter φ 1 of opening 63b greater than ion introducing hole 22a, this is a kind of design that can handle the positional fault of the ion introducing hole 22a that takes place when tank 20 is set.
To introduce that steam that hole 22a flows out is transformed into water droplet and the steam acceptance division 63c that drops on the part of tank 20 outer periphery surfaces is integrally formed around the outflow opening 63b of ajutage 63 from ion.

For example, when pressing process key 76 at every turn, the operator scheme of current type is switched to the operator scheme of another type relevant with the washing of operator scheme of a plurality of types on the process key 76 that is presented at 3 * 2 arrays continuously, and indicate the operator scheme of this another type.For example, this indication switches to the bottom from the top, and changes to the right side from left cut.Particularly, if process key 76 is by next time, then " standard " pattern is opened, if press process key 76 once more, then " standard " pattern is closed and " warm water " pattern is opened, if still press process key 76 once more, then " warm water " pattern close and " big part clothing " pattern is opened, thereby a kind of washing mode of Continuous Selection.
Equally, when pressing dry process key 77, can Continuous Selection and washing and dry relevant various operator schemes and the operator scheme of being correlated with drying.
In addition, guidance panel 7 is equipped with sterilization and deodorizing key 78 (command key).But sterilization and deodorizing key 78 be not for needing cleaning clothes the button that expectation is operated when clothing is carried out deodorizing.For example, if will have the clothing of smoke to be loaded in the cylinder 34 and press sterilization-deodorizing key 78, according to the number of times of pressing on display part 79 with following order " 10 ", " 30 ", " 10 " and " 30 " displaying contents.Here, underscore "-" expression sterilization and deodorizing operating period cylinder 34 are in rotation.When startup/Pause key 75 is pressed and show " 10 " or " 30 ", the air that comprises cation and anion is admitted to cylinder 34 and cylinder 34 does not rotate in the time period that shows, and with sterilization and deodorizing operation as with washing and the dry operation execution that separates.When startup/Pause key 75 is pressed and show " 10 " or " 30 ", the air that comprises cation and anion is admitted to cylinder 34 in the time period that shows, cylinder 34 rotations simultaneously, and with sterilization and deodorizing operation as with washing and the dry operation execution that separates.In other words, sterilization-deodorizing key 78 be do not need to wash and dry clothing on the button operated of the sterilization that separates of execution and washing and drying process and deodorizing.In this embodiment, the operation of being carried out when showing " 10 " or " 10 " refers to " 10-minute process ", and the operation of being carried out when showing " 30 " or " 30 " refers to " 30-minute process ".
On guidance panel 7, also be provided with other buttons and the various indicator of expression running status.Yet because they do not have and contact directly with the present invention, therefore omission is to their explanation.
Fig. 8 is the block diagram of the control circuit of drum washing-drying machine, and it has only shown and the parts relevant according to the unique operation of drum washing-drying machine of the present invention.Control circuit 8 (referring to Fig. 2) is equipped with the control section 81 (control device) that is made of CPU, ROM, RAM etc.Be sent to control section 81 from power supply opening key 72, startup/Pause key 75, sterilization-deodorizing key 78 and the control signal that is arranged on other buttons on the aforesaid operations panel 71.Be sent to control section 81 equally from being arranged on the thermal resistor 57 in the blower-casting 45 (referring to Fig. 4) and the detection signal of level sensor 58.In response to the control signal of delivering to control section 81, the operation of control section 81 index drum motors 36, fan electromotor 47, heater 44, ion generating device 61, ion supply fan electromotor 66, dry water supply valve 48, drain valve 33 and locking mechanism 56.
10-minute process: Fig. 9 shown by the sterilization in 10-minute and the deodorizing of control section shown in Figure 8 81 execution to operate the flow chart of the example of process, Figure 10 is the flow chart of example that has shown the on/off switch control of the heater among the step S113 shown in Figure 9, and Figure 11 is the flow chart of example of the rotary speed switching controls of the fan electromotor among the step S114 among Fig. 9.Figure 12 is the time diagram that has shown the operation of carrying out cylinder 34 during sterilization in 10-minute and the deodorizing operation process, locking mechanism 56, ion generating device 61, ion supply fan electromotor 66, fan electromotor 47, heater 44, dry water supply valve 48, drain valve 33 and Rolling motor 36.Next, the timing chart with reference to Figure 12 also mainly comes interpreter operation based on the flow chart of Fig. 8 to 11.
When process began in 10-minute, control section 81 operational lock mechanisms 56 (step S100), determine cylinder whether in rotation (step S101), and if underscore "-" be presented on the display part 79, then head roll motor 36 comes lentamente swing roller 34 (step S102) forward.
If underscore "-" is not presented on the display part 79, head roll motor 36 not then.In other words, carry out sterilization and deodorizing operation and swing roller 34 not.Carry out sterilization and deodorizing operation and not swing roller 34 for may be damaged, the clothing of distortion etc., that is, delicate garments is effective.
Afterwards, open fan electromotor 47 (step S103), and open heater 44 (step S104) by control section 81 simultaneously by control section 81.Therefore, the air in the cylinder 34 is via ajutage 39 circulations, and this air is heated by heater 44.Just as described later, the rotary speed of fan electromotor 47 is being switched between (3500rpm) and the low speed (1750rpm) at a high speed, so that reduce power consumption, and is set to high speed (3500rpm) when starting.
Equally, open ion generating device 61 (step S105), and open ion supply fan electromotor 66 (step S106) simultaneously.Therefore, introduce hole 22a from the cation of ion generating device 61 and anion via the ion of ajutage 63 and tank 20 upper left quarters and be fed to space between the cylinder outside, 34 back and the inboards, tank 20 back.Because the operation of pressure fan 42, this space has negative pressure, therefore, though the outflow opening 63b of ajutage 63 and the ion of tank 20 are introduced hole 22a and are provided with toward each other as mentioned above, but suction force is introduced between the 22a of hole and is worked flowing out opening 63b and ion, and cation and anion can be fed to this space efficiently by suction force.Ion generating device 61 and ion supply fan electromotor 66 are remained open mode, up to finishing sterilization and deodorizing operation.
Afterwards, open dry water supply valve 48 (step S107).At this moment, drain valve 33 still is in closed condition.Therefore, municipal water remains in the space between the peripheral surface outside of the peripheral surface inboard of tank 20 bottoms and cylinder 34 bottoms.The air circulation circulation of being heated by heater 44, and the municipal water that is contained in this space added hot air by this, thus water vapour appears on the surface of heat exchanger plate 41.Therefore, the clothing that is loaded in the cylinder 34 carries out steam treatment by the water vapour that heats, and it is soft to become when finishing.Because known humidity becomes high more, it is good more that the sterilization of cation and anion and deodorizing effect become, and therefore, the humidity in the cylinder 34 raise to increase the effect of cation and anion.In addition, be dissolved in the water vapour that floats in the cylinder 34, therefore improved the taste removal effect from the water-soluble odor compound of clothing.
If then can not be blown by water slug in ajutage 39 inboards.Therefore, between delivery period, by level sensor 58 level monitorings so that keep being no more than the water that needs, and if determine that water level has reached given water level (step S108), then close dry water supply valve 48 (step S109).
If determining water supply start afterwards through 3 minutes (step S110), then opens drain valve 33 (step S111), and opens dry water supply valve 48 (step S112).Therefore, the water that is held is discharged into outside the machine.Drain valve 33 is remained open mode, up to finishing sterilization and deodorizing operation.
Afterwards, carry out the on-off switching controls (step S113) of heater 44 based on temperature detection signal from thermal resistor 57.For example, as shown in figure 10,, then close heater 44 (step S202) if thermal resistor 57 detects 70 ℃ or higher temperature (step S201).If thermal resistor 57 detects 67 ℃ or lower temperature (step S203), then open heater 44 (step S204).Therefore, can realize low power consumption, and the internal temperature of cylinder 34 is remained on about 60 ℃.
Based on the testing result of the state that opens or closes and the thermal resistor 57 of heater 44, the rotary speed of control fan electromotor 47 is from switching to low speed at a high speed, or switches to (step S114) at a high speed from low speed.For example, as shown in figure 11, if heater 44 is in closed condition (step S301) and thermal resistor 57 detects 70 ℃ or lower temperature (step S302), then the rotary speed of fan electromotor 47 is set to low speed (1750rpm).If heater 44 is in open mode (step S301), then the rotary speed of fan electromotor 47 is set to (3500rpm) (step S304) at a high speed.Therefore, can realize low power consumption and low noise.
If sterilization and 34 rotations of deodorizing operating period cylinder, the clothing that then is loaded in the cylinder 34 stirs in cylinder 34 and is exposed to equably under cation and the anion, thereby improves sterilization and odor removal efficient.
On the other hand, if cylinder 34 is in halted state, the clothing that then is loaded in the cylinder 34 does not stir, and the air that will comprise cation and anion delivers on the clothing, thereby carries out sterilization and deodorizing operation on clothing.Clothing there is no fear of being damaged and in distortion in shape owing to sterilization and deodorizing operation.
In step S115, if determine to press after startup/Pause key 75, that is, after starting sterilization and deodorizing operation, passed through 8 minutes, then begin to cool down operation.Particularly, close heater 44 (step S116), and the rotary speed of fan electromotor 47 is set to (step S117) at a high speed.Therefore, the inside of cylinder 34 is cooled off fast.In this embodiment, even during cooling down operation, also ion generating device 61 and ion supply fan electromotor 66 are remained open mode.Yet they also can be closed.
In this 10-minute process, carry out 10 minutes sterilization and deodorizing operation.When having passed through 10 minutes, then definite sterilization and deodorizing operation are finished in step S118, and closed drum motor 36 (step S119), close fan electromotor 47 (step S120), close ion generating device 61 (step S121), close ion supply fan electromotor 66 (step S122), close dry water supply valve 48 (step S123), close drain valve 33 (step S124), and the operation (step S125) of the mechanism 56 that unlocks, thereby sterilization and deodorizing operation finished.
In sterilization and deodorizing operation, do not use ozone.Therefore, when the user opens on-off door 5 and takes out the clothing that is loaded in the cylinder 34, owing to do not comprise ozone in the air that exists in the cylinder 34, so the user can not smell uncomfortable ozone smell.
30-minute process: Figure 13 is the flow chart that has shown the example of the sterilization in 30-minute carried out by control section shown in Figure 8 81 and deodorizing operation process, and Figure 14 is the time diagram that has shown the operation of carrying out cylinder 34 during sterilization in 30-minute and the deodorizing operation process, locking mechanism 56, ion generating device 61, ion supply fan electromotor 66, fan electromotor 47, heater 44, dry water supply valve 48, drain valve 33 and Rolling motor 36.Next, the time diagram with reference to Figure 14 also mainly comes interpreter operation based on the flow chart of Figure 13.
When process began in 30-minute, control section 81 operational lock mechanisms 56 (step S400), determine cylinder whether in rotation (step S401), and if underscore "-" be presented on the display part 79, then head roll motor 36 comes lentamente swing roller 34 (step S402) forward.
If underscore "-" is not presented on the display part 79, head roll motor 36 not then.In other words, carry out sterilization and deodorizing operation and swing roller 34 not.Carry out sterilization and deodorizing operation and not swing roller 34 for may be damaged, the clothing of distortion etc., that is, delicate garments is effective.
Afterwards, open fan electromotor 47 (step S403), and open heater 44 (step S404) by control section 81 simultaneously by control section 81.Therefore, the air in the cylinder 34 is via ajutage 39 circulations, and this air is by heater 44 heating.Just as described later, the rotary speed of fan electromotor 47 is being switched between (3500rpm) and the low speed (1750rpm) at a high speed, so that reduce power consumption, and is set to high speed (3500rpm) when starting.
Equally, open ion generating device 61 (step S405), and open ion supply fan electromotor 66 (step S406) simultaneously.Therefore, cation that produces from ion generating device 61 and anion are introduced hole 22a via the ion of ajutage 63 and tank 20 upper left quarters and are sent into the space between the inboard behind the outside, cylinder 34 back and the tank 20.Because the operation of pressure fan 42, this space has negative pressure, therefore, though the outflow opening 63b of ajutage 63 and the ion of tank 20 introduce hole 22a as mentioned above away from and be provided with toward each other, but suction force is introduced between the 22a of hole and is worked flowing out opening 63b and ion, and cation and anion can be fed to this space efficiently by suction force.Ion generating device 61 and ion supply fan electromotor 66 are remained open mode, up to finishing sterilization and deodorizing operation.
Afterwards, open dry water supply valve 48 (step S407).At this moment, drain valve 33 still is in closed condition.Therefore, municipal water remains in the space between the peripheral surface outside of the peripheral surface inboard of tank 20 bottoms and cylinder 34 bottoms.By the air circulation circulation of heater 44 heating, and the municipal water that is contained in this space added hot air by this, thereby water vapour appears on the surface of heat exchanger plate 41.Therefore, the clothing that is loaded in the cylinder 34 carries out steam treatment by the water vapour that heats, and it is soft to become when finishing.Because known humidity becomes high more, it is good more that the sterilization of cation and anion and deodorizing effect become, and therefore, the humidity in the cylinder 34 raise to increase the effect of cation and anion.In addition, be dissolved in the water vapour that floats in the cylinder 34, therefore improved the taste removal effect from the water-soluble odor compound of clothing.
If then can not be blown by water slug in ajutage 39 inboards.Therefore, between delivery period, by level sensor 58 level monitorings, and if determine that water level has reached given water level (step S408), then close dry water supply valve 48 (step S409).
If determine to have passed through 3 minutes (step S410) after the water supply start, then open drain valve 33 (step S411), and open dry water supply valve 48 (step S412).Therefore, the water that is held is discharged into outside the machine.
Afterwards, carry out the on-off switching controls (step S413) of heater 44 based on temperature detection signal from thermal resistor 57.For example, as shown in figure 10,, then close heater 44 (step S202) if thermal resistor 57 detects 65 ℃ or higher temperature (step S201).If thermal resistor 57 detects 55 ℃ or lower temperature (step S203), then open heater 44 (step S204).Therefore, can realize low power consumption, and the internal temperature of cylinder 34 is remained on about 60 ℃.
Based on the testing result of the state that opens or closes and the thermal resistor 57 of heater 44, the rotary speed of control fan electromotor 47 is from switching to low speed at a high speed, or switches to (step S414) at a high speed from low speed.For example, as shown in figure 11, if heater 44 is in closed condition (step S301) and thermal resistor 57 detects 70 ℃ or lower temperature (step S302), then the rotary speed of fan electromotor 47 is set to low speed (1750rpm).If heater 44 is in open mode (step S301), then the rotary speed of fan electromotor 47 is set to (3500rpm) at a high speed.Therefore, can realize low power consumption and low noise.
If sterilization and 34 rotations of deodorizing operating period cylinder, the clothing that then is loaded in the cylinder 34 stirs in cylinder 34 and is exposed to equably under cation and the anion, thereby improves sterilization and odor removal efficient.
On the other hand, if cylinder 34 is in halted state, the clothing that then is loaded in the cylinder 34 does not stir, and the air that comprises cation and anion is sent on the clothing, thereby carries out sterilization and deodorizing operation on clothing.Clothing there is no fear of being damaged and in distortion in shape owing to sterilization and deodorizing operation.
In step S415, if determine to press after startup/Pause key 75, promptly, after starting sterilization and deodorizing operation, passed through 10 minutes, then close drain valve 33 (step S416), open heater 44 (step S417), and the rotary speed of fan electromotor 47 is set to (step S418) at a high speed.Therefore, municipal water is remained in the space between the outside of the inboard of tank 20 bottom peripheral surface and cylinder 34 bottom peripheral surface once more.By the air circulation circulation of heater 44 heating, and the municipal water that is contained in this space added hot air by this, thereby water vapour appears on the surface of heat exchanger plate 41.In other words, in 30 minutes processes, postpone to carry out twice with the regular hour water vapour offered the step of cylinder 34, thereby can carry out sterilization and deodorizing operation more up hill and dale than 10-minute process.
If then can not be blown by water slug in ajutage 39 inboards.Therefore, between delivery period, by level sensor 58 level monitorings so that keep being no more than the water that needs, and if determine that water level has reached given water level (step S419), then close dry water supply valve 48 (step S420).In the timing chart of Figure 14, dry water supply valve 48 does not cut out in this step.Though this means level sensor 58 at lasting level monitoring, water level does not reach given water level between delivery period.
If determine to have passed through 4 minutes (step S421) after the water supply start, then open drain valve 33 (step S422), and open dry water supply valve 48 (step S423) equally.Therefore, the water that is held is discharged into outside the machine.Drain valve 33 is remained open mode, up to finishing sterilization and deodorizing operation.
Afterwards, similar with above-mentioned steps, carry out the on-off switching controls (step S424) of heater 44 based on temperature detection signal from thermal resistor 57.Equally, based on the testing result of the state that opens or closes and the thermal resistor 57 of heater 44, the rotary speed of control fan electromotor 47 is from switching to low speed at a high speed, or switches to (step S425) at a high speed from low speed.
In step S426, if determine to press after startup/Pause key 75, that is, after starting sterilization and deodorizing operation, passed through 28 minutes, then begin to cool down operation.Particularly, close heater 44 (step S427), and the rotary speed of fan electromotor 47 is set to (step S428) at a high speed.Therefore, the inside of cylinder 34 cooling fast.In this embodiment, even during cooling down operation, also ion generating device 61 and ion supply fan electromotor 66 are remained open mode.Yet they also can be closed.
In this 30-minute process, carry out 30 minutes sterilization and deodorizing operation.When having passed through 30 minutes, then definite sterilization and deodorizing operation are finished in step S429, and closed drum motor 36 (step S430), close fan electromotor 47 (step S431), close ion generating device 61 (step S432), close ion supply fan electromotor 66 (step S433), close dry water supply valve 48 (step S434), close drain valve 33 (step S435), and the operation (step S436) of the mechanism 56 that unlocks, thereby sterilization and deodorizing operation finished.
In 10-minute process and 30-minute process, if press startup/Pause key 75 in sterilization and deodorizing operating period, then temperature is detected by thermal resistor 57.If being given forbidding, thermal resistor 57 detected temperature open the temperature (for example, 50 ℃) or lower of door, then closeall parts, for example heater 44, ion generating device 61, fan electromotor 47 and miscellaneous part.On the other hand, if temperature and locking mechanism 56 that thermal resistor 57 detected temperature are opened door above given forbidding remain open mode, then close all parts except that fan electromotor 47, for example heater 44, ion generating device 61 and miscellaneous part, and stop sterilization and deodorizing operation.Afterwards, the rotary speed of fan electromotor 47 is set at a high speed, and a large amount of wind is sent into cylinder 34 so that the inside of chilling roll 34.In 30 seconds, if detecting, thermal resistor 57 is equal to or less than the temperature that Men Wendu is opened in given forbidding, the open mode of the mechanism 56 that then unlocks.If thermal resistor 57 detected temperature still surpass the temperature forbid opening door, then a large amount of wind is sent into cylinder 34 so that the inside of chilling roll 34, the rotary speed of fan electromotor 47 remains high speed simultaneously.
Test examples: verify by following test according to the sterilization of the drum washing-drying machine of the embodiment of the invention and the deodorizing effect of deodorizing operation.
