And constitute it. The circulation pump 16 is provided with a washing water to be accumulated in the bottom of the outer tank 10 from the water vent 10b provided at the bottom of the outer tank 10, and is lifted via the bellows tube 29a and passed through the circulation pipe 17, the bellows pipe 29b. The washing water introduction port 145 and the circulation water path 18 are discharged.

Further, in the present embodiment, the circulation pump 16 is disposed on the left side of the bottom of the casing 1, and the circulation pipe 17 is extended upward in the front of the outer tank 10, and is changed to the upper portion of the outer tank 10 to be changed to The rear side is passed to the left side of the opening 1a (refer to FIG. 1), and is connected to the washing water introduction port 145 positioned at the left end of the outer tank cover 14. In this way, by arranging the circulation pump 16 and the circulation pipe 17 and the washing water introduction port 145 on the left side (one side) in the left-right direction (wide direction) of the washing machine 100, the length of the circulation pipe 17 can be shortened ( The pressure loss with respect to the wash water can be reduced by the shortest length.

Further, the inner diameter (diameter) of the circulation pipe 17 is formed to be larger than the inner diameter (diameter) of the circulation pipe of the prior art. For example, the inner diameter of the circulation pipe 17 is 32.5 mm, and the inner diameter of the prior art circulation pipe is 19.5 mm. In this way, by making the circulation pipe 17 thicker than the prior art, it is possible to reduce the pressure loss when the washing water flows, and it is possible to make the circulation flow rate of the washing water flowing in the circulation pipe 17 larger than the previous one. Technology has increased.

In the rear portion of the washing machine 100, a water supply solenoid valve 4 is provided, and above the water supply solenoid valve 4, a connection port 4a for supplying tap water (clean water) is formed. Inside the connection port 4a, a water supply filter (not shown) is provided, and the garbage contained in the tap water is here. The place was removed. The washing water is drained through the drain valve 15 and the drain pipe 24 as needed. Further, tap water is introduced into the inner tank 9 via the bellows tube 29c.

The drying unit 60 is provided with a drying unit upper line 61 disposed along the upper surface of the casing 1 and a slightly L-shaped portion along the side surface and the bottom surface of the casing 1. Air line 66. The air discharged from the water vent 10b is sent to the upper unit 61 of the drying unit via the air line 66. Inside the air line 66, a cold water dehumidifying portion 67 is provided. This is for the flow of tap water to cool the air flowing in the air line 66 and to condense the vapor in the air.

The air that has been cooled and dehumidified by the cold water dehumidifying unit 67 is further lowered in humidity by the drying screen 65, and then flows into the upper unit 61 of the drying unit. On the upper portion of the drying screen 65, a drying fan 64 and a drying motor 63 for driving the same are provided. Further, in the subsequent stage of the drying fan 64, the heater 62 is disposed, and the air to be blown is heated therein. The heated air is discharged into the inner tank 9 via the drying duct 22, the bellows tube 29d, and the outer tank cover 14.

At the outer tank cover 14, at the discharge port of the air from the drying unit 60, a mist grid 80 (micronized member) formed by meshing a thin metal wire into a slight hemisphere is attached. Further, above the mist grid 80, the mist nozzle 70 protrudes downward from the drying unit upper line 61. The mist nozzle 70 is formed in a cylindrical shape having an inner diameter of about 1.5 mm, and is connected to the water supply solenoid valve 4 via the mist pipe 4b.

When the tap water is supplied to the mist nozzle 70 via the mist tube 4b, the tap water sprayed downward from the mist nozzle 70 collides with the mist grid 80, and the tap water is finely atomized (atomized) and spread to the inner tank 9 Inside. Therefore, the mist nozzle 70 and the mist grid 80 constitute a mist spreading device. Here, the mesh of the mist grid 80 is preferably thicker than a water supply screen (not shown) provided inside the connection port 4a. Thereby, it is possible to prevent the mist grid 80 from being clogged due to the garbage in the tap water. Further, by arranging the mist grid 80 below the mist nozzle 70, the water sprayed from the mist nozzle 70 is accelerated by the gravitational acceleration and collides with the mist grid 80. Thereby, the refinement of water can be further promoted.

The use of water (fog) after miniaturization is, for example, the following two points.

Use 1: In the initial stage of washing laundry, the clothes are wetted by spreading the mist, and the dirt of the clothes is easily peeled off.

Use 2: When drying the laundry after washing, the clothes are wetted by spreading the mist while blowing the clothes, and the wrinkles of the clothes are removed.

In the present embodiment, the water sprayed from the mist nozzle 70 collides with the mist grid 80 to make the water fine. This is a method of making the water finer by the momentum of the water to be ejected. By this, even in the case where the wind force is weak or the wind power is not obtained at all, the water can be sufficiently refined. In any of the above-mentioned "use 1" and "use 2", the flow rate ejected from the mist nozzle 70 is 10 kg per kg of the washing and dewatering capacity. 0.1L/min~1.0L/min is ideal, and it is more desirable to be 0.2L/min~0.4L/min.

Further, by blowing the warm air through the drying unit 60, the heat energy of the warm air can be further supplied, and the water can be further refined. Further, in this case, since the water adhering to the mist grid 80 can be blown by the warm air, it is possible to prevent the metal ions (magnesium or the like) contained in the tap water from coming out of the mist grid 80. Up, it is possible to prevent clogging of the mist grid 80.

When the washing machine 100 is used, the outer tub 10 is rocked, and the outer tank cover 14 is also shaken. Therefore, the positional relationship between the mist nozzle 70 and the mist grid 80 varies. In the present embodiment, the mist mesh 80 is formed in a slightly hemispherical shape, and even if the relative positional relationship between the mist mesh 80 and the mist nozzle 70 is slightly changed, the function of refining the water can be continuously exhibited. Further, in the present embodiment, since the mist grid 80 is provided on the downstream side of the dryer screen 65 in the air blowing path of the warm air, the chips are dried during the drying operation. The screen 65 is removed. Thereby, it is possible to prevent the mist grid 80 from being clogged due to the filaments or the like.

Figure 6, as illustrated in Figure 5, in order to combine the upper pipe upper unit 61a and the upper pipe lower unit 61b, and to connect the mist pipe 4b at the mist nozzle 70, and further to the drying pipe 22 The state of the bellows tube 29d is connected.

Fig. 7 is a perspective cross-sectional view showing the state in which the upper unit 61 of the drying unit is attached to the outer tank cover. In Fig. 7, the various parts of the periphery are also illustrated. As shown in FIG. 7, the mist nozzle 70 is positioned above the vertical direction of the mist grid 80. Further, the mist pipe 4b is disposed from the upper side of the mist nozzle 70 toward the water supply solenoid valve 4.

(Pipe structure after water supply solenoid valve 4)

Fig. 8 is a perspective view showing the piping structure behind the water supply solenoid valve 4. After the water supply solenoid valve 4, a connection port 4c is protruded. This connection port 4c is connected to the mist nozzle 70 via the mist tube 4b (refer to FIG. 7). Further, a mist valve 160 that is a solenoid valve is disposed on the lower left side of the water supply solenoid valve 4, and tap water is supplied to the mist valve 160 from the water supply solenoid valve 4 via the pipe 161.

Further, at the mist valve 160, a pipe 162 is also connected, and the pipe 162 is connected to the cold water dehumidifying portion 67 (refer to FIG. 2) via the pipe 163. In the case where the mist valve 160 is in the ON state (water-passing state), the water is supplied to the cold water dehumidifying unit 67 via the path indicated by the broken line via the tube 161, the mist valve 160, the tube 162, and the tube 163.

On the other hand, when the mist valve 160 is in the OFF state (non-water-passing state), tap water is supplied to the mist nozzle 70 via the connection port 4c. When the mist valve 160 is in the ON state (water-passing state), the tap water is supplied to the cold water dehumidifying unit 67, and if it is in the OFF state (non-water-passing state), the tap water is supplied to the mist nozzle 70. .

In FIGS. 3 to 8 , the configuration of the mist nozzle 70 and the drying unit 60 have been described, but are not limited thereto. For example, there is a general configuration described below.

(1) The configuration in which the water is made fine by the momentum of the water is not limited to the above embodiment. That is, as long as it is When the water sprayed from the mist nozzle 70 is collided to make the water finer, the mist grid 80 can be used instead. For example, instead of the mist grid 80, a plate that is inclined with respect to the direction in which the water is ejected may be used.

(2) Further, instead of the mist grid 80, for example, a rod-shaped member may be used as the refining member. However, when the washing machine 100 is used, the outer tub 10 is rocked, and the outer tank cover 14 is also shaken. Therefore, when a rod-shaped micronized member is applied, it is preferable to fix the micronized member. The positional relationship between the drying line 22 and the like and the mist nozzle 70 is made constant.

(3) In the above embodiment, the mist grid 80 is disposed vertically below the mist nozzle 70. However, the positional relationship between the two is not limited thereto, and may be arbitrarily arranged. For example, the mist grid 80 can also be placed above the mist nozzle 70. However, since the mist grid 80 is disposed below or obliquely below the mist nozzle 70, the momentum of the water sprayed by the mist nozzle 70 is increased by the gravitational acceleration, so that the water is miniaturized. , is more ideal.

(4) Further, instead of the mist nozzle 70 and the mist grid 80 which are the mist spreading means, the spray nozzle can be used to refine the water. Since the spray nozzle also utilizes the momentum of water to refine the water, such a configuration is also included in the scope of the present invention.

(outer groove 10 in which the inner groove 9 is accommodated)

Figure 9 is a perspective view showing the outer groove in which the inner groove is accommodated. In addition, in Fig. 9, the state in which the inner cover (not shown) provided in the outer tank cover 14 is removed is shown.

The portion 11a and the plurality of drain through holes 11b. The raised portion 11a is provided with a surface that is inclined in the circumferential direction and inclined in the radial direction so that the outer peripheral portion is sequentially increased. In the present embodiment, the raised portion 11a is provided in two places (only one of which is shown), but the present invention is not limited to two places, but may be three or more places. Further, the ridge shape of the pulsating blade 11 is merely an example, and is not limited to the embodiment.

By rotating the pulsating wing disk 11, the laundry on the pulsating wing disk 11 is slid on the pulsating wing disk 11 while rotating in the rotational direction of the pulsating wing disk 11, and is pushed up by the ridge portion 11a. And move in the up and down direction. At this time, by washing the water with the washing water circulation mechanism 50 (refer to FIG. 2) while circulating the washing water, the washing water can be spread over the laundry. According to this configuration, even if the washing water is not stored in the inner tank 9 and the laundry is immersed in the washing water, the laundry can be washed, and the water can be greatly reduced. Further, if the washing water can be uniformly spread on the laundry, the washing power is increased, which contributes to the shortening of the washing time. In addition, the detailed structure for uniformly dispersing the washing water will be described later.

As shown in FIG. 10, the laundry input port 141 is provided with a straight portion 1411 which is positioned further rearward than the center O of the radial direction and extends in the left-right direction (wide direction) and compared with a linear portion 1412 that is positioned further forward and extends in the left-right direction at a center O in the radial direction, and a circular arc portion that connects one end (left end) of the straight portion 1411 and one end (left end) of the straight portion 1412 1413 and an arc portion 1414 that connects the other end (right end) of the straight portion 1411 and the other end (right end) of the straight portion 1412. another The shape of the laundry inlet port 141 in plan view is not limited to the shape of FIG. 10, and for example, the straight portion 1412 may be formed in an arc shape and formed into a substantially radius shape as a whole. Further, the outer peripheral portion of the laundry inlet port 141 of the outer tank cover 14 is opposed to the fluid balancer 12 when the outer tank cover 14 is attached to the outer tank 10.

The water passage cover 30 is formed on the back surface of the outer tank cover 14 (the surface on the inner tank 9 side), and the water passage cover 30 and the outer tank cover 14 constitute a circulating water passage 18 (refer to FIG. 2). In addition, the water passage cover 30 is provided with a discharge port 31 (return port) which is slightly triangular in shape when viewed in plan and extends linearly along the straight portion 1411 of the laundry inlet 141. This discharge port 31 is formed to be shorter than the straight portion 1411.

Moreover, the water passage cover 30 is attached to the one end side (left end side) of the discharge port 31, and the washing water introduction port 145 is located. Further, the water passage cover 30 is provided with a linear outer peripheral portion 32a extending along the straight portion 1411 and extending from one end (left end, right side) of the peripheral portion 32a toward the wash water introduction port 145. The peripheral portion 32b and the outer peripheral portion 32c are extended from the other end (right end, left side in the drawing) of the outer peripheral portion 32a toward the wash water introduction port 145. Further, the outer peripheral portion of the water passage cover 30 is fixed to the outer tank cover 14 by screws at a plurality of places. Further, the outer peripheral portion of the water passage cover 30 and the outer tank cover 14 are formed into a watertight structure by interposing a gasket (not shown).

In this manner, in the present embodiment, the outer water tank cover 14 and the water passage cover 30 constitute a circulating water passage 18 that passes through the discharge port 31 from the washing water introduction port 145. Circulating water is formed by the outer tank cover 14 On one side (upper surface) of the wall of the road 18, the amount of protrusion from the outer tank cover 14 toward the lower side (the inner groove 9 side) can be reduced, and the washing water can be dispersed from a higher position.

In the circulating water passage 18, a plurality of guide projections are provided, and the washing water is guided substantially uniformly toward the discharge port 31. When the washing water is discharged from the discharge port 31, even if it is affected by the gravity, the washing water can be hit in the vicinity of the rotation center O1 (refer to FIG. 11) of the inner tank 9. Further, even when the amount of the laundry to be charged into the washing tub is about to reach the rated amount (refer to line H3 of Fig. 12(a)), the position of the laundry in the mission can be close to the inner groove 9. The center O1 is rotated, and the washing water can be dispersed for the entire laundry.

Further, the discharge port 31 is elongated and formed into a slit shape in the left-right direction (the width direction of the washing machine 100). The width Wa of the discharge port 31 is set to be within the range of the inner diameter D1 (refer to FIG. 2) of the fluid balancer 12 and may be more than half of the maximum width Wmax of the laundry input port 141 (50). %the above). Thereby, it is possible to spread the washing water to the entire laundry without bringing the washing water into contact with the fluid balancer 12. In addition, if the width Wa is less than half (less than 50%) of the maximum width Wmax, it is difficult to spread the washing water to the entire laundry in the inner tank 9. Further, in the present embodiment, the wide Wa is set to about 70% of the maximum width Wmax.

(spray shape of the washing water circulation mechanism 50)

Figure 11 is a view of the spray shape of the wash water circulation mechanism 50. Schematic diagram shown. In addition, FIG. 11 is a plan view showing a state in which the inner tank 9 is housed in the outer tank 10 and the outer tank cover 14 is attached to the opening of the outer tank 10 (the inner lid is not shown). Further, the position of the discharge port 31 is shown by a thick solid line. As shown in FIG. 11, when the washing water Q (referred to as a thick two-dot chain line) is discharged from the discharge port 31, it is dispersed in a film shape from the entire width direction of the discharge port 31. In addition, the washing water Q which is discharged from the discharge port 31 is wider toward the left and right outside than the left and right end portions 31a and 31b of the discharge port 31, and is wider than the width Wa of the discharge port 31. The web is spit out in a film form. In addition, the washing water Q that has just been discharged from the discharge port 31 is wider than the wide Wa. However, after that, the width of the washing water Q is reduced, and the washing water Q hits the inner tank 9 The position of the bottom surface (pulsating wing disk 11) is equal to the width Wa of the discharge port 31. When the washing water Q is discharged from the discharge port 31, the width Wa of the discharge port 31 is wider, and then it is reduced, and finally, it is equal to the width Wa of the discharge port 31. The width is wide on the laundry.

Figure 12 (a) is a side cross-sectional view showing the positional relationship between the height of the laundry and the spray in the present embodiment, and Figure 12 (b) is the height of the laundry in the comparative example. The positional relationship between the sprays is shown as a side profile view. In addition, Fig. 12(b) is a view schematically showing a case where the washing water is dispersed in a conical shape.

As shown in the comparative example of FIG. 12(b), centrifugal force is used to lift the washing water from the inner tank 9 at the outer tank cover 14. In the case of the waterway cover 200 that is ejected in a conical shape, as shown by the height H20, when the height of the laundry (clothing) is low, the washing water relative to the laundry can be washed. The spread area is sufficiently ensured, and the wash water can be dispersed for the entire laundry. However, as shown by the height H10, when the laundry is at a high load, the washing water touches the laundry before the diffusion, and the distribution area of the washing water with respect to the laundry is lowered. It is also possible to disperse the wash water only for a part of the laundry. In this way, as the amount of load increases, the area of the washing water is reduced, which is a cause of a decrease in the detergency or a non-uniform washing.

Therefore, in the present embodiment, as shown in Fig. 12(a), the configuration in which the washing water (circulating water) Q is dispersed in a horizontal shape is used. In this way, the washing water Q is dispersed in a horizontal shape (one character in the vertical direction of the paper surface), regardless of the height of the laundry (clothing) at a low load as shown by the height H3. In the case of the case of the height of the laundry (clothing) at a high load as shown by the height H4, it is possible to disperse and wash the entire laundry without changing the distribution area of the washing water Q. water. Further, when the washing water Q is dispersed, even if the washing water Q is in the shape of a horizontal line, by rotating the pulsating blade 11 or the inner groove 9, the washing water Q can be dispersed to the entire washing material. At the office. In this way, in the present embodiment, even if the load amount (cloth height) is increased, the area of the washing water to be washed does not change, and the cleaning unevenness and the high load can be achieved. Increased detergency.

Further, by widening the wide Wa and widening the opening area of the discharge port 31, it is not necessary to concentrate the washing water as in the comparative example (refer to FIG. 12(b)). Therefore, it is easy to discharge the washing water having a larger flow rate than the comparative example from the discharge port 31. Further, in the present embodiment, the circulation pipe 17 (the path of the circulation pump 16) which is returned from the bottom of the inner tank 9 to the upper portion of the outer tank cover 14 is made thick (inner diameter: 19 mm → 32.5 mm) to reduce the pressure loss, and the flow rate can be increased without increasing the rotational speed of the motor of the circulation pump 16 (23 L/min → 40 L/min).

In addition, when a fan piece is provided on the lower side (back side) of the pulsator (pulsating wing), and by rotating the fan piece, it is passed through a circulating water path (housing) provided in the inner groove by centrifugal force. In the case of washing the water raft and forming it from the slit formed in the casing, it is affected by the amount of the laundry in the inner tank or the amount of the washing water, and if it is the laundry which is put into the inner tank When it is increased, the amount of water is reduced, and it becomes impossible to stably disperse the washing water to the laundry. However, in the present embodiment, since the circulation pump 16 is used to circulate the washing water, the amount of the washing water discharged from the discharge port 31 can be made slightly constant.

Further, in the present embodiment, since the circulation water passage 18 can be formed into a flat shape compared to the comparative example using the centrifugal force, the discharge port 31 can be disposed at the upper edge of the inner tank 9 The upper surface 12a of the fluid balancer 12 (refer to FIG. 11(a)) is further on the upper side, and the distance between the longer washing and the discharge port 31 can be ensured. (The drop in water is large), and it is possible to improve the detergency.

(control block)

Figure 13 is a control block diagram of a washing machine in accordance with an embodiment of the present invention. As shown in FIG. 13, the microcomputer 40 (control device) is connected to the operation key input circuit 41 to which the operation key switches 6 are connected, the water level sensor 21, the temperature sensor 26, and the vibration sensing. The device 27 is connected and obtains various key operations of the user and various information signals in the washing engineering and drying process. Further, the microcomputer 40 is connected to the water supply solenoid valve 4, the clutch 13b, the drain valve 15, the circulation pump 16, the motor 13a, the drying fan 64, the heater 62, the mist valve 160, and the like via the drive circuit 42. And control the opening and closing or rotating and energizing of these. Further, the microcomputer 40 is a display 25 formed of a 7-stage light emitting diode for notifying the user of the operating state of the washing machine, a display 7 made of a light emitting diode, and a buzzer 43. Make a connection.

Next, the control process of the washing machine of the present embodiment will be described.

Fig. 14 is a flow chart showing a part of the control process of the washing machine in the embodiment of the present invention. Fig. 15 is a flow chart showing another part of the control process of the washing machine of the embodiment of the present invention. Fig. 16 is an explanatory view showing changes in the temperature of the laundry in the washing process of the warm water Niagara waterfall containing warm water mist. In the present embodiment, before the formal laundry process (step S120), First, a warm water Niagara waterfall washing process including warm water mist blowing is performed (step S110).

In the microcomputer 40, if the power switch 5 (refer to FIG. 12) is pressed and the power is turned on, the basic control processing program for washing and drying shown in FIGS. 14 and 15 is executed. As shown in FIG. 14, in step S101, the microcomputer 40 performs status check and initial setting of the washing machine 100.

In step S102, the microcomputer 40 lights up the displays 7, 25 (refer to FIG. 13) of the operation panel 8 (refer to FIG. 1), and sets the laundry stroke in accordance with an input instruction from the operation of the key switch 6. In the state where there is no input instruction, the standard laundry stroke or the previous laundry stroke is automatically set.

In step S103, the microcomputer 40 monitors the input of the start switching signal from the start switch (operation key switch) of the operation key switch 6 of the operation panel 8. When it is determined that there is no input of the start switching signal, the microcomputer 40 repeats the processing of step S103. When it is determined that there is a case where the input of the start switching signal is present, the process proceeds to step S104.

In step S104, the microcomputer 40 performs a washing dose detecting process. This washing dose detecting process is based on the action of rotating the flapping disk 11 in one direction while the inner tank 9 is stationary, in a state where the washing material before the washing water is supplied as a dry cloth. The amount of the laundry is detected by the amount of the rotation load at the pulsating wing 11 to be carried out. Microcomputer 40 for motor 13a and clutch 13b For control, and based on the amount of cloth detected, the appropriate amount (washing amount) of the lotion is taken out. The washing dose is taken out by referring to a comparison table between the cloth amount and the washing amount set in advance.

Specifically, the detection of the amount of cloth used by the variable-frequency drive motor as the motor 13a is performed by detecting the arrival rotational speed when power is supplied for a specific time so that the motor 13a is rotated. It. The detection of the amount of cloth by the capacitor split-phase single-phase induction motor as the motor 13a is performed after the power is turned off in a state where the motor 13a is always raised to the saturation rotational speed. The inertial rotation deceleration characteristic is detected and carried out. Further, the ideal washing dose is obtained by referring to the comparison table between the cloth amount and the washing amount set in advance.

Further, the amount of washing water is set such that the amount of washing water is maintained so as not to exceed the water level of the pulsating blade 11 and accumulate in the bottom of the outer tank 10 when the amount of cloth is within a specific amount (the appropriate amount). (water level h1).

Further, the microcomputer 40 determines the washing time based on the detection result (the amount of cloth) and sets it. When the amount of cloth is not detected, the standard washing time is set.

In step S105, the microcomputer 40 displays the requested washing amount on the display 25 of the operation panel 8.

In step S106, the microcomputer 40 turns on the lotion supply solenoid valve (not shown), and performs the lotion supply to the lotion input chamber of the lotion and the additive container 28 (refer to Fig. 1). In addition, the user is Before the water supply to the lotion, the indicated amount of the powder lotion is put into the lotion input chamber of the lotion, the additive container 28 (refer to FIG. 1), and then the outer cover 3 (refer to FIG. 1) is closed. To operate. The powder lotion which is put into the lotion supply chamber in which the lotion is supplied with water is passed through the lotion and the additive container 28 together with the water of the lotion supply water and is dropped to the bottom of the outer tank 10.

In step S107, the microcomputer 40 stops the supply of the lotion after the water supply is performed until the level of the lotion is dissolved. In this embodiment, the amount of the water supply to the lotion is set to, for example, about 10 liters regardless of the amount of washing (amount of cloth). The amount of water is a sufficient amount of water to stir the water and the lotion supplied to the bottom of the inner tank 9 when the inner tank 9 is rotated in the subsequent dissolution of the lotion (step S108). Also, it is set such that the water surface is lower than the height below the pulsating wing disk 11 (the washing system is not wetted before the lotion is dissolved).

In step S108, the microcomputer 40 is rotated on the bottom surface of the inner groove 9 by causing the inner groove 9 and the pulsating blade 11 to rotate integrally in a single direction (for example, about 70 rotations per minute). The lotion dissolved water and the powder lotion to be fed to the bottom of the outer tank 10 are dissolved by the detergent which is stirred and produces a high detergent concentration of the washing water. The time during which the lotion dissolves is, for example, set to 1 minute. Even at low temperature (low water temperature) and difficult to dissolve powder lotion, it will have a dissolution rate of about 90%. The concentration of the wash water produced is about 7 times the standard concentration. Here, the standard concentration is, for example, a ratio of a powder washing dose of 20 g / a washing water amount of 30 liters.

Next, in step S110, the microcomputer 40 executes the warm water Niagara waterfall cleaning process (steps S111 to S115).

Process (1): In step S111 (first project), the microcomputer 40 performs preparatory laundry. In this preparatory laundry, first, the stirring of the pulsating wing disc 11 is performed intermittently without fixing the inner tank 9 or in a free state, and by pulsating the flap The cycle pump 16 is operated in the forward and reverse rotation of 11 to wash the washing water (washing water) at the bottom of the outer tank 10 by the circulation pump 17, and then wash from the outer tank cover 14 The water introduction port 145 introduces the wash water into the water passage cover 30. Thereafter, the washing water is spread onto the laundry in a horizontal shape from the discharge port 31 formed in the water passage cover 30. In this manner, since the washing water is dispersed from the discharge port 31 while the pulsating blade 11 is rotating forward and backward, the washing water can be distributed to the entire laundry (clothing). In the process of step S111, the washing water (washing water) having a high lotion concentration can be dispersed for the laundry, and the washing can be performed in a state where the washing water having a sufficiently high lotion concentration is contained in the laundry.

In step S112, the microcomputer 40 drains the residual water that is not contained in the laundry. Further, when the water level of the residual water reaches a situation where water is not immersed below the water level in the air line 66 (refer to Fig. 2), the drainage treatment may not be performed.

(2): In the step S113 (the second item), the microcomputer 40 activates the heater 62 of the drying unit 60 and the drying fan 64, and sets the mist valve 160 to the OFF state (non-water-passing state). ,borrow Thereby, tap water is supplied to the mist nozzle 70 via the connection port 4c. That is, the water sprayed from the mist nozzle 70 collides with the mist grid 80 to make the water finer and atomized. By this, the clothes are heated by warm wind and fog. Since only the water contained in the laundry (that is, the minimum amount of water necessary) is heated, the laundry is easily heated compared to the case where the water is simply heated, and the consumption can be suppressed. The effect of the amount of electricity. Moreover, by raising the temperature of the laundry, the oil stain can be quickly decomposed.

Process (3): In step S114, the microcomputer 40 turns on the water supply solenoid valve 4 and supplies a small amount (for example, 10 liters) of tap water (clean water).

Process (4): In step S115 (third item), the microcomputer 40 is configured to intermittently perform pulsation without making the inner tank 9 fixed or free. The wing plate 11 is agitated by forward and reverse rotation, and the circulating pump 16 is operated by the forward and reverse rotation of the pulsating wing disk 11, and the washing water (washing water) at the bottom of the outer tank 10 is circulated by the circulation pump. In the upper side, the washing water is introduced into the water passage cover 30 from the washing water introduction port 145 formed at the outer tank cover 14.

By circulating the washing water with the circulation pump 16, the clothes heated by the treatment in the step S113 and the heat conduction from the inner tank 9 generate warm water (for example, a warm water system). It is 30 ° C or more). By stirring while spraying the warm water from the discharge port 31, the oil stain which is decomposed (floated) in the process of step S113 can be detached from the clothes and flow into the water. By heating up the clothes The increase in the moisture content of the material reduces the uneven cleaning. Further, if the stirring is continued without spreading the warm water spray, the clothes are wound and the water content is reduced. Therefore, in the present embodiment, the mixture is stirred while being sprayed with warm water. Moreover, since the water temperature is not easily lowered during the stirring operation, it can be washed by warm water spraying even without special treatment such as a heater. The above is the washing process of the warm water Niagara waterfall in step S110. After washing in the warm water Niagara Falls, the system moves to formal laundry treatment (treatment (5)). Referring to Fig. 16, a description will be given of a change in the temperature of the laundry in the washing process of the warm water Niagara waterfall containing warm water mist.

The temperature of the laundry shown in Fig. 16 is a schematic display of the results of the experiment in which the temperature sensor was attached to the laundry. The horizontal axis is time and the vertical axis is clothing temperature. In the step S111 of the treatment (1), the laundry temperature is a temperature generated by the dispersion of the washing water. In step S113 of the process (2), the temperature of the laundry is heated and raised by the air supply of the warm water mist. In step S114 of the process (3), the temperature of the laundry is caused by a slight temperature drop due to the stop of the supply of the warm water mist. In the step S115 of the treatment (4), the temperature is maintained by the dispersion of the washing water by the shower with warm water. Further, in the main laundry treatment of the treatment (5), the laundry temperature is set to be warm (for example, 25 to 30 ° C) because the laundry and the inner tub 9 are heated in the treatment (4).

Returning to Fig. 14, in step S120, the microcomputer 40 performs formal laundry. In this formal laundry, first of all, by the The same method is used to carry out the volume measurement, and the tap water (clean water) is supplied as water until it becomes the set water level. Thereafter, the stirring is carried out for about 2 minutes and the mixing of the cloth is about 1 minute. The stirring for about 2 minutes is performed while the inner tank 9 is stationary, and the pulsating blade 11 is made positive. The reverse rotation of the circulation pump 16 causes the washing water (laundry water) accumulated in the bottom of the outer tank 10 to be discharged from the discharge port 31 formed at the water passage cover 30 to the washing water circulation at the laundry. The loose agitation causes the pulsating blade 11 to rotate forward and backward while stopping the operation of the circulation pump 16 and stopping the circulation of the washing water (washing water).

In addition, in the configuration in which the washing water is blown onto the laundry with a large strength as in the prior art, the bouncing of the water occurs on the surface of the laundry, and the outer tank cover is also caused. The problem of dirty inside the cover. However, in the present embodiment, by widening the opening of the discharge port 31, it is possible to ensure a large flow rate even without discharging the washing water with a large amount of strength. Therefore, since the washing water can be dispersed without being blown onto the laundry with a large strength, it is easy to permeate the washing water into the laundry. Further, since the effect of eliminating the foam of the lotion which occurs in the inner tank 9 during the main laundry is also performed, it is possible to suppress the foaming more than necessary. Therefore, it is possible to prevent a decrease in the detergency caused by the buffering action of the foam of the lotion. Further, it is possible to smoothly perform drainage after the main laundry, and also has an effect of preventing foaming during dehydration.

Thereafter, in step S120, the microcomputer 40 stops the circulation of the pump 16 and stops washing (washing) for about 1 minute. In the state of circulation of the water-repellent water, the pulsating wing disk 11 is uniformly agitated in forward and reverse rotation, and then the official laundry is finished.

As shown in Fig. 15, in step S121, the microcomputer 40 performs the first water washing. In the water washing, first, the drain valve 15 is opened and the washing water (laundry water) accumulated in the bottom of the outer tank 10 is drained, and then the inner tank 9 and the pulsating wing 11 are integrally rotated in one direction. The washing water contained in the laundry is centrifugally dehydrated. The rotational speed of the inner tank 9 and the pulsating wing 11 at the time of this centrifugal dehydration is set to the same rotational speed as the rotational speed (about 1000 rpm) in the final dehydration which will be described later. By this, a dehydration operation with a high dehydration rate is achieved.

After that, the microcomputer 40 closes the drain valve 15 and rotates the inner tank 9 and the pulsating wing 11 in a single direction in a single direction (35 to 40 rpm), and opens the water supply solenoid valve 4 to discharge tap water (clean water). Water is supplied from the water spout 157 to the laundry on the pulsating wing disk 11.

Thereafter, the microcomputer 40 performs the washing water supply so that the water level at the bottom of the outer tank 10 does not exceed the set water level h1 in a state where the rotation of the inner tank 9 and the pulsating wing 11 is stopped.

Thereafter, the microcomputer 40 is the same as the press-type laundry agitation in the main laundry (step S110), and the circulation pump is rotated while the inner groove 9 is stationary. 16 is operated to spread the washing water (washing water) accumulated in the bottom of the outer tank 10 from the discharge port 31 of the water passage cover 30 to the pulsating wing disk 11. In the manner of washing, the washing water is circulated and washed by stirring.

Thereafter, the microcomputer 40 detects the water level of the washing water accumulated at the bottom of the outer tub 10 while the rotation of the pulsating blade 11 and the operation of the circulation pump 16 are stopped, so that the water level is not The water is replenished in a manner that exceeds the set water level h1.

After that, the microcomputer 40 executes the washing water that is stored in the bottom of the outer tub 10 while the pulsating flap 11 is rotated forward and backward while the inner tub 9 is stationary. The washing water is discharged from the discharge port 31 to the laundry on the pulsating blade 11, and is circulated by washing and rinsing. At this time, the washing water (washing water) discharged from the discharge port 31 of the water passage cover 30 is evenly distributed to the laundry, and the lotion component contained in the laundry can be efficiently diluted, and Can improve the cleaning performance.

Thereafter, the microcomputer 40 performs uniform agitation for continuing the forward and reverse rotation of the pulsating blade 11 in a state where the circulation of the circulation pump 16 is stopped and the circulation of the washing water is stopped.

In step S122, the microcomputer 40 performs the second water washing. In the second water washing, the soft additive water supply solenoid valve (not shown) is opened, and water is supplied to the soft additive supply chamber of the lotion and the additive container 28 (refer to FIG. 1). The soft additive is introduced into the control of the soft additive in the chamber to be introduced into the bottom of the outer tank 10. In addition, the other operations were carried out in the same manner as the first water washing.

In step S123, the microcomputer 40 performs final dehydration. In the final dewatering, the washing and dewatering driving device is operated such that the inner tank 9 and the pulsating wing 11 are integrally rotated at a speed of about 1000 rpm in one direction while maintaining the drain valve 15 in an open state. The laundry in the inner tank 9 is centrifugally dehydrated. The operation time of this final dehydration is set to a time at which the desired dehydration rate can be obtained.

In step S124, the microcomputer 40 determines whether or not the washing and drying process is set. When it is determined that the washing and drying stroke is not set (S124, N), the microcomputer 40 skips step S125 and ends the processing, and when it is determined that the washing and drying stroke is set (S124, Y) Then, the process proceeds to step S125.

In step S125, the microcomputer 40 performs drying when the washing and drying stroke is set. In the drying process, while the drain valve 15 is maintained in the open state, the pulsating blade 11 is rotated forward and backward while the inner tank 9 is stationary, in the same state as the washing stroke. The drying fan 64 (refer to FIG. 2) in the dry unit 60 operates. Thereby, the air in the outer tank 10 is sucked into the air line 66 from the venting water outlet 10b (refer to FIG. 2), and is disposed in the air tube by passing through the air line 66. The cold water dehumidifying portion 67 in the road 66 is contacted by the cooling water which is dripped, and is cooled and dehumidified. The air that has been cooled and dehumidified is collected by the fluff filter, and after being heated by the heater 62, it is blown in from the warm air introduction port 146 (refer to FIG. 3). Inside the slot 9.

After that, the microcomputer 40 is on one side by the temperature sensor 26 (Refer to Fig. 13) The drying is performed while monitoring the temperature of the warm air, and when the ratio of the temperature change becomes a specific value, the drying is ended.

As described above, according to the washing machine 100 of the present embodiment, the washing water which is a high-concentration lotion liquid is returned from the washing water returning to the discharge port 31 in the inner tank 9 before the main laundry. It is spread and the laundry contains a sufficiently high concentration of the lotion liquid (the first project), and then heated by the warm water mist (second work), so that the temperature of the clothes can be increased. It can make the oil decompose and disengage more quickly.

Further, after the water supply, the circulating water pump 16 circulates the water for the water supply (the third process), and the warm water can be generated by the heated clothes and the heat conduction from the inner tank 9. . Further, by stirring the warm water to the clothes, the oil which has been decomposed can be detached from the clothes and flow into the water.

Further, according to the washing machine 100 of the present embodiment, the washing water is returned to the discharge port 31 in the inner tank 9, and is provided at the position (inner diameter D1) of the fluid balancer 12 and further inside (refer to 2), and the wide width is set to a width (refer to FIG. 10) in which the laundry is put into the maximum width Wmax of the laundry input port 141 in the inner tub 9 (refer to FIG. 10), and can be taken from the discharge port 31. The washing water in the shape of a wide and wide water can be used to spread the washing water (washing water) during washing and the washing water (washing water) during washing to the entire washing. As a result, it is possible to uniformly disperse the washing water to the laundry, and it is possible to reduce the unevenness of the laundry and to improve the detergency.
