The mixing chamber 66 is located below the detergent dissolving chamber 45 and the finishing agent charging chamber 46 and communicates with the overflow channel 56 through holes 56a and 56b. The bottom wall 21d of the mixing chamber 66 is formed with a low slope on the front side, and has an outlet 59 at the lowest position. The outlet 59 is connected to the water inlet 19 of the outer tank upper cover 28 by a flexible tube 19a.
[0034]
The upper part of the left side wall of the detergent dissolving chamber 45 and the upper part of the right side wall of the finishing agent charging chamber 46 are provided with guide rails 58a and 58b composed of upper and lower rails. It can be mounted on. Further, guide rails 59a and 59b of the detergent tray 74 are provided on the lower side of the guide rail 58a and the right side wall of the detergent dissolving chamber 45.

The circular port 21a is open to the mixing chamber 66, the oval port 21b is open to the detergent dissolution chamber 45, and the oval port 21c is open to the finishing agent charging chamber 46.
[0036]
The L-shaped piping unit 83 is installed in close contact with the right side to the back of the detergent dissolving vessel 21. The piping unit 83 has four water supply channels formed therein. One of the water supply channels is connected to a water supply solenoid valve, and the other is connected to the water supply port provided in the detergent container 21.
[0037]
On the side of the piping unit 83, there are four ports (85a, 86a, 87a, 88a) for attaching four electromagnetic water supply valves. A main water supply solenoid valve 20 for supplying water to the washing and dewatering tub 2 is supplied to the port 85a, an auxiliary water supply solenoid valve 22 for supplying water to the detergent dissolution chamber 45 is provided for the port 86a, and an auxiliary water supply solenoid valve for supplying water to the finishing agent introduction chamber 46 is provided for the port 87a. The cooling water sprinkling electromagnetic valve 24a for supplying water to the cooling water sprinkling section 24 is attached to the port 88a of the cooling water sprinkling part 22a. A rubber bush 92 is fitted into each port for water sealing.
[0038]
The port 85a communicates with a water supply flow path 85b, and a pipe 85 is attached to an end of the water supply flow path 85b. Further, in the middle of the water supply flow path 85b, there are a priming water supply port 90 to the bath water pump 81, a bath water inlet port 89 from the bath water pump 81, and a cleaning water supply port 91 via a throttle 91a. A rectifying plate 85d is provided at a branch portion of the priming water supply port 90, so that priming water is supplied to the bath water pump 81 reliably. The bath water pump 81, the priming water supply port 90, and the bath water inlet 89 are connected by a hose.
[0039]
Although not shown, the cleaning water supply port 91 is connected to the upper part of the water-cooled dehumidifying duct 23 by a bellows hose. The lint generated during the drying process may accumulate on the upper wall surface of the water-cooled dehumidifying duct 23 and the cooling water sprinkling section 24. Therefore, when water is supplied by the main water supply solenoid valve 20, a small amount of water is sprinkled from the cleaning water supply port 91 to a portion where the lint is accumulated, so that the lint is dropped below the water-cooled dehumidification duct 23, and the lint is cleaned.
[0040]
The port 86a communicates with a water supply channel 86b, and an L-shaped pipe 86 that opens downward is attached to the end of the water supply channel 86b.
[0041]
The port 87a communicates with a water supply channel 87b, and an L-shaped pipe 87 that opens downward is attached to the end of the water supply channel 87b.
[0042]
The port 88a communicates with a water supply channel 87b, and a water supply port 88 to the cooling sprinkler 24 is attached to the end of the water supply channel 87b.
[0043]
The water supply passage 85b and the water supply passage 88b communicate with each other through a small hole 92a, and the water supply passage 86b and the water supply passage 88b communicate with each other through a small hole 92b. These small holes are provided for draining water in the water supply channel, and are for preventing freezing in the piping unit 83.
[0044]
The attachment of the piping unit 83 to the detergent dissolving vessel 21 is performed by inserting the L-shaped pipe 86 into the oblong port 21b, inserting the L-shaped pipe 87 into the oblong port 21c, and sliding downward until it hits the lower end of the circular port. This is performed by pushing the pipe 85 into the circular port 21a in which the rubber bush 67 is fitted. Further, although not shown, the piping unit 83 is screwed to the detergent dissolving container 21 to fix them.
[0045]
Water from the auxiliary water supply solenoid valve 22 which is a water supply means (first water supply means) for supplying water to the detergent dissolution chamber 45 flows into the detergent dissolution chamber 45 through the L-shaped pipe 86. On the inner side wall of the detergent dissolving chamber 45, the water and the detergent entering from the L-shaped pipe 86 are stirred by the detergent stirring blades 50 to generate a high-concentration detergent solution, and the high-concentration detergent solution is supplied to the first water supply means. The overflow edge 45d for overflowing the overflow channel 56 when the volume is increased by dilution with additional water supply from the auxiliary water supply solenoid valve 22, and the upper and lower sides for suppressing the rotation of the detergent-dissolved water (high-concentration detergent solution) during stirring. A plurality of triangular prism-shaped ribs 45c that are long in the direction are provided. The rib 45c makes it difficult for the water surface of the detergent liquid during stirring to become mortar-shaped, and prevents the detergent liquid from overflowing from the overflow edge 45d during stirring.
[0046]
In addition, the bottom wall 45a of the detergent dissolving chamber 45 is provided with a detergent agitating blade 50 rotatably provided substantially at the center thereof, and a detergent liquid or water in the detergent dissolving chamber 45 mixed at a corner on the side of the finishing agent introducing chamber 46. A siphon water flow mechanism 47 that flows out into the chamber 66 is provided. In the present embodiment, the detergent stirring blade 50 rotates in the direction of arrow R (see FIG. 8), so that the detergent-dissolved water flows counterclockwise in the figure.
[0047]
The bottom wall 45a of the detergent dissolution chamber 45 has an inclined surface such that the siphon water passage mechanism 47 is at the lowest. However, a portion facing the detergent stirring blade 50 is a horizontal plane 45a1 substantially parallel to the detergent stirring blade 50. The siphon water passage mechanism 47 is provided on a bottom surface 45b one step lower than the bottom of the bottom wall 45a so as to minimize residual water in the detergent dissolving chamber 45. The bottom wall 45a and the bottom surface 45b are smoothly connected by an inclined surface to smooth the flow of detergent-dissolving water around the siphon water passage mechanism 47 and prevent the accumulation of detergent.
[0048]
The siphon water passage mechanism 47 is composed of a siphon pipe 47b that is long in the vertical direction and a siphon cap 47a whose bottom is open. The siphon cap 47a covers the siphon pipe 47b, and is installed with a gap with the siphon pipe 47b. A hole 47c is provided at the center of the siphon pipe 47b, and communicates with the mixing chamber 66. The height of the siphon pipe 47b is set slightly lower than the overflow edge 45d so that the siphon can be reliably conducted. On the upper surface of the siphon cap 47a, a handle 47g that is gripped when the siphon cap 47a is attached or detached is provided.
[0049]
The siphon cap 47a is positioned vertically and horizontally with respect to the siphon pipe 47b by vertical ribs 47f1 and 47f2 provided at substantially equal intervals on the outer periphery of the siphon pipe 47b. Thereby, the siphon cap 47a is set concentrically with the siphon pipe 47b so as to have a gap z between the bottom surface of the siphon cap 47b and the bottom surface 45b of the detergent melting chamber 45.
[0050]
Further, a thin plate-shaped current plate 47d which is long in the vertical direction is provided below the outer peripheral surface of the siphon cap 47a. The bottom surface of the current plate 47d protrudes from the bottom surface of the siphon cap 47a (the amount of protrusion is equal to the gap z between the bottom surface of the siphon cap 47a and the bottom surface 45b of the detergent dissolving chamber 45). The bottom surface of the plate 47d contacts the bottom surface 45b of the detergent dissolution chamber 45. The width direction of the current plate 47d and the longitudinal direction of the handle 47g of the siphon cap 47a are in a positional relationship orthogonal to each other.
[0051]
When setting the siphon cap 47a, the width direction of the rectifying plate 47d is set to be substantially orthogonal to the flow direction of the detergent-dissolved water by the detergent stirring blades 50. For this reason, when setting the siphon cap 47a, it is necessary to pay attention to the direction of the siphon cap 47a. Therefore, an axially long guide rail 47e is provided on the inner peripheral surface of the siphon cap 47a so as to sandwich the vertical rib 47f1 so as to facilitate the positioning of the siphon cap 47a in the circumferential direction. That is, by aligning the guide rail 47a with the vertical rib 47f1, the current plate 47d is automatically oriented in the correct direction.
[0052]
As described above, the back panel 11 is provided with the opening 94 used when attaching and detaching the siphon cap 47a. The opening 94 has a circular shape and is provided with a notch 94a so that the current plate 47d can pass therethrough. The direction in which the notch 94a is provided is made to coincide with the flow direction of the detergent-dissolving water. That is, the direction of the siphon cap 47a is automatically determined by inserting the rectifying plate 47d into the notch 94a.
[0053]
Furthermore, since the axial dimension of the vertical rib 47f1 is made larger than that of the other vertical ribs 47f2 and is substantially the same length as the siphon pipe 47b, the siphon cap 47a is inserted through the opening 94, and immediately put on the siphon pipe 47b. Since the vertical rib 47f1 is sandwiched between the guide rails 47e, the direction of the current plate 47d can be easily set so as to be orthogonal to the flow direction of the detergent-dissolving water. Therefore, when attaching the siphon cap 47a, there is no need to perform work while looking through the opening 94, and workability is greatly improved.
[0054]
The current plate 47d functions to prevent conduction of the siphon water passage mechanism 47 during detergent dissolution and to prevent clogging of the siphon water passage mechanism 47 due to undissolved detergent.
[0055]
Water from the main water supply solenoid valve 20, which is a water supply means (second water supply means) for supplying water to the laundry 38, flows into the mixing chamber 66 from the circular pipe 85 of the piping unit 83.
[0056]
The high-concentration detergent liquid generated in the detergent dissolution chamber 45 is diluted and increased in volume by the water supplied from the auxiliary water supply solenoid valve 22 as the first water supply means, and flows down from the overflow channel 56 and the siphon water flow mechanism 47 to the mixing chamber 66. I do. Here, the water merges with the water from the second water supply means, is diluted, and flows out from the outlet 59 to the water inlet 19.
[0057]
The flow rate of the tap water flowing from the circular pipe 85 into the mixing chamber 66 varies depending on the tap water pressure. However, when the tap water pressure is high, the tap water flows into a jet and collides with the front side wall 56c of the detergent container 21 to flow back through the holes 56a and 56b. And may flow into the detergent dissolution chamber 45 and the finishing agent introduction chamber 46. In order to avoid this, a rectifying member 75 is provided in the mixing chamber 66. The rectifying member 75 is porous with a high porosity, and is made by, for example, entanglement of plastic fibers. The jet flow is decelerated in the flow regulating member 75 and spreads and flows over the entire mixing chamber 66, so that backflow to the holes 56a and 56b can be prevented.
[0058]

The bottom wall 46b of the finishing agent charging chamber 46 has a lower inclined surface at the front, and the siphon water passage mechanism 48 is provided at the lowest part thereof. The finishing agent (liquid) in the finishing agent input chamber 46 is diluted and increased in volume by receiving water from the L-shaped pipe 87, overflows from the overflow edge 46a into the overflow channel 56, flows down from the hole 56b, and flows through the siphon water passage mechanism. From 48 flows into the mixing chamber 66. Here, the water merges with the water from the second water supply means, is diluted, and flows out from the outlet 59 to the water inlet 19.
[0059]

Small blades 50b are provided on the surface of the stirring blade 50 so as to improve the dissolving efficiency of the detergent.
[0062]
A labyrinth seal mechanism 60 having a maze-like clearance is formed by the lower surface of the detergent stirring blade 50 and the bottom wall of the detergent dissolution chamber 45. The labyrinth seal mechanism 60 is used to prevent the detergent liquid and the zeolite particles in the detergent from entering the shaft seal member 57 to prevent the shaft seal member 57 and the stirring blade drive shaft 51 from being damaged, and to prevent the detergent liquid from leaking. It is provided.
[0063]
The detergent charging container 73 is a box having a flat rectangular shape and an open top, and includes a detergent charging portion 68, a finishing agent charging portion 69, and a handle portion 80. The detergent introduction section 68 is located above the detergent dissolution chamber 45, and the finish introduction section 69 is located above the finish introduction chamber 46. The detergent introduction section 68 and the finish introduction section 69 are surrounded by a frame 70. The detergent charging container 73 is guided so as to sandwich the frame 70 between the guide rails 58a and 58b provided on the detergent dissolving container 21, and moves forward and backward.
[0064]
As shown in FIG. 8, the frame body 70 on the opposite side of the handle portion 80 has a convex portion 70b projecting downward, and has a cutout portion 70c substantially at the center of the convex portion 70b. The cutout portion 70c is provided at a position where the handle portion 47g of the siphon water flow mechanism 47 fits when the detergent charging container 73 is mounted on the detergent dissolving container 21 and is pushed in all the way. If the detergent pouring container 73 is pushed in when the siphon cap 47a is displaced in the circumferential direction, the handle 47g of the siphon cap 47a collides with the convex portion 70b, and the detergent dissolving container 73 cannot be completely pushed. That is, by providing the notch 70c, it is easy to determine whether or not the siphon cap 47a is set in the correct direction.
[0065]
The handle portion 80 is located at a portion on the front side of the detergent input container 73, and functions as a grip portion that is exposed to a wall surface on the back side of the outer garment input port 9 a formed on the top cover 9 and performs a forward / backward operation.
[0066]
The detergent introduction section 68 includes a detergent tray 74, a shielding plate 84, and a top plate 70a. The top plate 70 a is provided above the frame 70 so as to surround the detergent introduction section 68.
[0067]
The detergent tray 74 has left and right wall surfaces 74a, a front side wall surface 74c, and a bottom wall inclined toward the rear side, and has a thin box shape with upper and rear sides open. Outer surfaces of the left and right wall surfaces 74a are provided with pins 77a and 77b on the near side and pins 78a and 78b on the far side. The pins 77a and 77b are rotatably fitted into holes provided in the frame 70, and the detergent tray 74 is supported rotatably about the pins 77a and 77b. A torsion spring 79 is provided outside the pin 77b. One end of the torsion spring 79 is fixed to a stopper 74b provided on an outer surface of a wall surface 74b of the detergent tray 74, and the other end is fixed to a top plate 70a. The torsion spring 79 acts to rotate the detergent tray 74 upward (the detergent tray 74 rotates counterclockwise in FIG. 13). The left and right wall surfaces 74a of the detergent tray 74 hit the top plate 70a and stop rotating (the state of FIG. 13).
[0068]
When the detergent input container 73 is set in the detergent dissolving container 21, the pins 78a and 78b of the detergent tray 74 are pressed against the lower surfaces of the guide rails 59a and 59b by the action of the torsion spring 79. When the detergent container 73 is moved back and forth, the pins 78a and 78b move along the guide rails 59a and 59b, so that the detergent tray 74 rotates and swings around the pins 77a and 77b. When the detergent input container 73 is pulled out from the detergent dissolving container 21, the pins 78a and 78b finally hit the stoppers 59a1 and 59b1 of the guide rails 59a and 59b, and the detergent input container 73 cannot be pulled out any further. On the back side of the detergent tray 74, a shielding plate 84 provided on the top plate 70a is provided.
[0069]
The finishing agent introducing section 69 has a bottom wall 76 having a lower inclined surface on the back side, and has an opening on the back side of the bottom wall 76.
[0070]
Next, the operation of each step of the washing and drying machine configured as described above will be described. FIG. 14 is a flowchart of each step executed by the microcomputer 16a in the control unit 16.
[0071]
When the washing start button switch of the input switch group 14a is turned on, the microcomputer 16a executes the following control processing.
[0072]
Step 401
When the user puts the laundry 38 into the washing and dewatering tub 2, operates the input switch group 14a of the operation panel 14 to perform the initial setting, and presses the washing start button switch, the microcomputer 16a performs Start the automatic operation control process.
[0073]
In the initial setting, a washing course according to the laundry 38, and a washing time, a dehydration time, a water amount, a number of rinses, and the like are set as necessary. Further, when washing and drying are performed, a washing and drying course is set.
[0074]
Step 402
A detection control process of the laundry amount of the laundry 38 is performed. This cloth amount detection is performed by controlling the electric operation clutch mechanism 62 of the driving device 6 to the stirring mode in a dry cloth state before water supply, energizing the driving motor 61 for a short time to rotationally drive the stirring blades 4, and increasing the rotation speed. , Or the deceleration characteristics in the inertial rotation when the power supply to the drive motor 61 is stopped. Based on this detection result (the amount of laundry of the laundry 38), the amount of washing water and the amount of detergent for generating washing water having a preferable detergent concentration are calculated and determined, and this amount of detergent is displayed by the display element group 14b. , And display a reminder to put detergent. The user grasps the handle portion 80 and pulls out the detergent input container 73 into the outer clothing input port 9a.
[0075]
When a predetermined amount of powdered synthetic detergent is put into the detergent tray 74 with reference to the indicated detergent amount, the powdered synthetic detergent forms a mountain shape, but a part of the powdered synthetic detergent falls into the detergent melting chamber 45 while sliding on the bottom wall of the detergent tray 74. Then, a part remains on the detergent tray 74. Further, if necessary, when the finishing agent is supplied to the finishing agent input section 73d, the finishing agent flows down to the finishing agent input chamber 21d.
[0076]
Thereafter, when the detergent charging container 73 is pushed in, the pins 78a and 78b are pushed down by the guide rails 59a and 59b, and the detergent tray 74 rotates clockwise to increase the angle, and all the detergent remaining on the detergent tray 74 becomes detergent. It falls into the melting chamber 45. When the detergent dissolving container 73 is further pushed in, the detergent tray 74 rotates to the left by the action of the torsion spring 79, and the angle decreases again. In the detergent dissolving container 73, the handle portion 80 hits the front side wall 17 a of the back panel box 17 and stops.
[0077]
Step 403
Produces highly concentrated detergent liquid. When it is detected that the powdered synthetic detergent has been introduced into the detergent dissolution chamber 45, the auxiliary water supply solenoid valve 22 is opened and a small amount of tap water (detergent dissolution water) is supplied from the L-shaped pipe 86 into the detergent dissolution chamber 45. Then, a display indicating that the detergent is being melted is performed by the display element group 14b, the detergent stirring motor 39 is energized to rotate the detergent stirring blade 50, and the powder synthetic detergent in the detergent melting chamber 45 is melted while being stirred. This produces a highly concentrated detergent solution.
[0078]
When the stirring is started, the water surface of the detergent liquid in the detergent dissolving chamber 45 becomes low in the central part and high in the side wall surface due to the rotation of the detergent stirring blade 50. Furthermore, since the detergent dissolving chamber 45 has a square shape, the flow direction changes sharply at the corners, so that the water level at the corners particularly rises. For this reason, when the water level rises from the upper surface of the siphon pipe 47b, the siphon water passage mechanism 47 may conduct and the dissolved detergent liquid may escape, or undissolved detergent particles may be clogged in the siphon cap 47a. .
[0079]
The current plate 47 d is provided so as to block the flow on the upstream side in the flow direction of the detergent liquid with respect to the siphon water flow mechanism 47. For this reason, the pressure in the lower gap z of the siphon water flow mechanism 47 on the back of the rectifying plate 47d decreases (the pressure is lower during the rotation of the detergent agitating blade 50 than when it is stationary). Therefore, the water level rise in the siphon water passage mechanism 47 can be suppressed, the water surface does not rise to the upper surface of the siphon pipe 47b, and the siphon water passage mechanism 47 does not conduct during the stirring of the detergent liquid.
[0080]
The pressure in the gap z changes depending on the size and position of the current plate 47d. For example, the pressure decreases as the width X of the current plate 47d increases, but if it is too large, undissolved detergent tends to stay on the rear surface of the current plate 47d. In order to reduce the pressure in the gap z and prevent the undissolved detergent from staying, the dimension of the current plate 47d is set to a width X of 6 to 10 mm and a height H of at least 30 mm (the maximum is the height of the siphon cap 47a. The position of the rectifying plate 21m is preferably such that the distance between the rectifying plate 21m and the siphon cap 47a is 0 to 4 mm, and the center of the siphon cap 47a substantially coincides with the center of the rectifying plate 21m.
[0081]
Step 404
The electric operation clutch mechanism 62 of the driving device 6 is controlled to the dewatering / drying mode, and the driving water motor 61 is operated at a low speed to rotate the washing / dewatering tub 2 and the stirring blade 4 at a low speed, and the main water supply solenoid valve 20 is opened to supply tap water. Is supplied directly to the water inlet 19 to perform pre-water supply in which the tap water is sprayed on the laundry 38 in the washing / dewatering tub 2. The pre-water supply amount is an amount (4 to 10 L) that at least the top surface of the laundry 38 to a portion of about several cloths is wetted. The pre-water supply is performed in order to promote the penetration of the high-concentration detergent solution into the laundry 38 in the next spraying of the high-concentration detergent solution and to prevent color unevenness due to the fluorescent whitening agent contained in the detergent.
[0082]
Step 405
With the detergent stirring blades 50 still rotating, the electric operation clutch mechanism 62 of the driving device 6 is controlled to the dehydrating / drying mode, and the driving motor 61 is operated at a low speed to rotate the washing and dewatering tub 2 and the stirring blades 4 at a low speed. Then, the auxiliary water supply electromagnetic valve 22 is opened to supply water to the detergent dissolution chamber 45. The high-concentration detergent solution in the detergent dissolution chamber 45 is diluted and increased, the water level rises, overflows from the overflow edge 45d, and flows down from the holes 56a, 56b of the overflow channel 56 to the mixing chamber 66. At the same time as the auxiliary water supply electromagnetic valve 22, the main water supply electromagnetic valve 20 is opened to supply tap water from the circular pipe 85 to the mixing chamber 66. In the mixing chamber 66, the high-concentration detergent solution is diluted with tap water into a preferable high-concentration detergent solution, and is sprayed from the outlet 59 to the laundry 38 in the washing and dewatering tub 2 to permeate.
[0083]
Since the high-concentration detergent liquid penetrates into the laundry 38, the chemical detergency of the high-concentration detergent liquid (actions such as penetration emulsification and dispersion) acts on the dirt attached to the laundry, and the dirt is applied to the laundry. It is in a state that can be easily removed from.
[0084]
Step 405a
Cleaning is performed to remove bubbles floating on the water surface in the detergent dissolution chamber 45. Elimination of bubbles is achieved by stopping the power supply to the detergent stirring motor 39, stopping the rotation of the detergent stirring blades 50, and continuing to supply water from the auxiliary water supply solenoid valve 22, so that the water level in the detergent dissolution chamber 45 rises and the overflow edge From 45, bubbles on the water surface flow out. In order to efficiently remove bubbles, the detergent stirring blade 50 may be intermittently rotated for a short time. By doing so, the water level rises at the start of rotation of the detergent stirring blade 50, and a large amount of bubbles can be discharged from the overflow edge 45d.
[0085]
Finally, the auxiliary water supply electromagnetic valve 22 is closed. The water in the detergent dissolution chamber 45 is discharged from the siphon water passage mechanism 47.
[0086]
Step 406
The laundry 38 in which the high-concentration detergent solution has descended and penetrated is left for a predetermined time. This deferment is a time for further promoting the penetration of the high-concentration detergent solution into the laundry 38 and the effect of the detergent's chemical detergency on stains, and is omitted as necessary.
[0087]
Step 407
The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened to start supplying tap water (wash water). This water supply may be performed simultaneously with the cleaning for removing bubbles in step 405a. The supply of the wash water is performed up to the amount of water determined in step 402, but the supply of the wash water is interrupted in order to detect the amount of cloth (the value of the compress) and the quality of the laundry during the supply of water (at this point, the cleaning in step 405a is stopped). If not completed, only the main water supply electromagnetic valve 20 is closed, and the auxiliary water supply electromagnetic valve 22 is kept open to continue cleaning). The suspended water level is a water level suitable for detecting the amount of compress and the quality of the cloth set in the microcomputer 16a in advance.
[0088]
Step 408
The amount of the compress and the quality of the cloth are detected to correct the amount of water supplied for washing and to determine the washing process (washing process and rinsing process). In this cloth detection, the water supply is interrupted at a predetermined low water level, the electric operation clutch mechanism 62 of the driving device 6 is controlled to the stirring mode, the driving motor 61 is energized for a short time, and the stirring blade 4 is rotationally driven. The first deceleration characteristic (amount of compress cloth) in the inertia rotation at the time of deenergization is detected, and then the water supply is resumed, the washing water is replenished to a predetermined high water level, the water supply is interrupted, and the drive motor of the drive device 6 is stopped. 61 is energized for a short time to rotate the stirring blade 4 to detect a second deceleration characteristic in the inertial rotation at the time of deenergization, and to perform washing based on a difference between the first attenuation characteristic and the second attenuation characteristic. The cloth of the object 38 is detected. This cloth detection control is omitted when it becomes unnecessary by the initial setting. Then, the time and the water flow (the intensity of mechanical stirring) in the washing and rinsing steps are determined according to the fabric quality.
[0089]
Step 409
Tap water is supplied up to the water amount (water level) determined in step 402. By this water supply, the washing water is diluted with a high-concentration detergent solution to a detergent concentration (1 time) preferable for washing. As a result, the laundry 38 is immersed in the washing water having a predetermined detergent concentration (1 time) in the washing / dewatering tub 2.
[0090]
Step 410
The driving device 6 is controlled so as to perform the washing process with the washing water flow and the washing time set in step 408. In this washing step, the driving device 6 controls the electric operation clutch mechanism 62 to the washing mode, and repeats the forward / reverse operation of the driving motor 61 to repeatedly repeat the washing / dewatering tub 2 and the stirring blade 4 in the opposite direction. Rotate. At this time, the dirt has already been easily removed, and even if the mechanical force applied to the laundry is reduced, a high detergency can be obtained, and cloth tangling and cloth damage can be suppressed.
[0091]
When the washing step is started, the detergent dissolving chamber 45 is cleaned. The cleaning has already been performed in step 405a, and there is usually no detergent left in the detergent dissolution chamber 45. This cleaning is performed in order to eliminate the detergent even if it remains, so as not to leave the detergent in the detergent dissolution chamber 45. The cleaning method is the same as in step 405a.
[0092]
Step 411
Open the drain solenoid valve 33 to drain the washing water out of the machine
Step 412
The main water supply electromagnetic valve 20 and the auxiliary water supply electromagnetic valve 22 are opened to supply rinsing water (tap water) to a set water amount. At this time (when water is supplied for final rinsing when performing a plurality of rinsings), the auxiliary water supply electromagnetic valve 22a is also opened and a softening agent is supplied as necessary.
[0093]
Step 413
The rinsing process is executed by controlling the driving device 6.
[0094]
Step 414
The drainage solenoid valve 33 is opened to drain the rinse water out of the machine.
[0095]
Step 415
With the drainage electromagnetic valve 33 kept open, the electric operation clutch mechanism 62 of the driving device 6 is controlled to the dehydration / drying mode, and the driving motor 61 is operated at a high speed, so that the washing and dewatering tub 2 and the stirring blade 4 are integrally formed. By rotating at high speed, the water content of the laundry 38 is centrifugally dehydrated. If the washing course has been selected, the operation ends in this step.
[0096]
Step 416
The electric operation clutch mechanism 62 of the driving device 6 is controlled to the dewatering / drying mode, the driving motor 61 is operated at a low speed, and the blower 26 is operated while rotating the washing and dewatering tub 2 and the stirring blade 4 at a low speed. 5 is sucked out from the suction port 5a, and is cooled and dehumidified by cooling water supplied from the cooling water sprinkling section 24 into the water-cooled dehumidifying duct 23 in the process of ascending the water-cooled dehumidifying duct 23. , And is sent from the circulation fan 26 to an outlet 30 through an ascending air duct 27 and a heater 29, heated by the heater 29, and directed toward the vicinity of the inner wall surface of the washing and dewatering tub 2. The circulating air blown in the direction opposite to the rotation direction is generated, and the laundry in the washing / dewatering tub 2 is dried.
[0097]
When the laundry 38, which has been centrifugally dehydrated and adhered to the side wall of the washing and dewatering tub 2, is dried with hot air, wrinkles are generated in the laundry 38. Therefore, during the drying time, the stirring blade 4 is periodically turned on. The laundry 38 is dried by moving the laundry 38 forward and backward. The control of the hot air drying step is executed while monitoring the detection signals of the humidity sensor 40, the first temperature sensor 41, and the second temperature sensor 42, and ends when a desired degree of drying is obtained.
[0098]
