29 is a drying duct provided on the inner side of the back side of the casing 1 in the longitudinal direction, and the lower portion of the duct is connected to the air inlet 2a provided below the back side of the outer tank 2 by a rubber bellows tube B29a. In the drying duct 29, a water-cooling dehumidifying mechanism (not shown) is built in, and the cooling water is supplied from the water supply solenoid valve 16 to the water-cooling dehumidifying mechanism. The cooling water flows down along the wall surface of the drying duct 29, enters the outer tank 2 from the intake port 2a, and is discharged from the drain port 21.

The upper portion of the drying duct 29 is connected to a filter duct 27 which is disposed in the front-rear direction on the upper right side of the casing 1. An opening is formed in the front side surface of the filter duct 27, and a lead-out type drying filter 8 is inserted into the opening. The air that has passed from the drying duct 29 to the filter duct 27 flows into the screen filter 8a of the drying filter 8, and the yarn is removed. The cleaning of the drying filter 8 takes out the drying filter 8 and takes out the screen type filter 8a. Further, an opening portion is formed in the bottom surface of the insertion portion of the drying filter 8 of the filter duct 27, and the opening portion is connected to the intake duct 33, and the other end of the intake duct 33 is connected to the intake port of the air blowing unit 28.

The blower unit 28 is constituted by a motor 28a for driving, a fan impeller (not shown), and a fan case 28b. A heater 31 is built in the fan case 28b to heat the air sent from the fan impeller. The discharge port of the air blowing unit 28 is connected to the warm air duct 30. The air blowing unit 28 constitutes a blowing device, and the heater 31 constitutes a heating device.

As shown in Fig. 13, the warm air duct 30 is connected to the warm air blowing port 32 provided in the outer tank cover member 2d via a rubber bellows pipe 30a and a bellows pipe joint 30b. In the present embodiment, the air blowing unit 28 is provided on the upper right side in the casing 1. Therefore, the warm air blowing port 32 is provided at the obliquely upper right position of the outer tank cover 2d so that the distance up to the warm air blowing port 32 is as short as possible.

A temperature sensor (not shown) is provided at the air inlet port and the air outlet of the air outlet 21 and the air blowing unit 28.

In the washing and drying machine having the configuration shown in Fig. 1 to Fig. 5, when the wind is high, the high-speed wind directly hits the clothes or the like, and the wind can be used to flatten the wrinkles generated by the clothes or the like. For this reason, it is necessary to generate the high-speed wind blowing unit 28 and the warm air blowing port 32 that allows the wind to directly hit the clothes or the like. The necessary performance of the air blowing unit 28 will be described later. The warm air blowing port 32 will be described in detail with reference to Figs. Fig. 6 is a front view of the outer tank cover 2d in the portion where the warm air outlet 32 is provided. Fig. 7 is a cross-sectional view of the warm air outlet 32 shown after the two-point chain line A-A of Fig. 6 is cut.

As shown in Fig. 6, the warm air outlet 32 is provided along the opening 2c from the front side of the outer tank cover 2d, and the flow paths 32b and 32c are formed inside. Install the bellows joint 30b at the inlet of the warm air outlet 32, in the flow The outlet of the path 32c forms a nozzle 32d. In order to prevent the gap between the washing and dewatering tank 3 and the outer tank cover 2d from entering the laundry, the inner diameter of the opening portion 2c of the outer tank cover member 2d is set to be almost the same as the inner diameter of the opening portion 3a of the washing and dewatering tank 3. . Therefore, the outlet portion 32a forming the warm air blowing port 32 protrudes further inward than the inner peripheral surface of the opening portion 2c, and the nozzle 32d opens toward the inside of the washing and dewatering tank 3. In this manner, the warm air coming out of the nozzle 32d directly hits the laundry in the washing and dewatering tank 3.

Here, if the amount of protrusion of the outlet portion 32a is too large, the movement of the laundry is hindered during washing or drying. Therefore, as shown in FIGS. 6 and 7, the nozzle is formed into a flat slit shape to reduce the amount of protrusion, and The surface shape of the opening portion 2c and the outlet portion 32a changes smoothly. Further, the flow path 32b and the flow path 32c are formed without any undesired protrusions or a sudden change in the flow direction, and the flow path area toward the nozzle 32d is gradually reduced. In this manner, the pressure loss or fluid sound generated when the high-speed air flows through the flow paths 32b, 32c can be made small.

The flow of wind during the drying operation is as follows. When the air blower unit 28 is operated, when the heater 31 is energized, a high-speed warm air is blown from the nozzle 32d into the washing and dehydrating tank 3 (arrow 41: Fig. 2, Fig. 4, Fig. 5), and the wet clothes are hit, because the clothes are worn. It is warm clothing and the water evaporates. The high-temperature and high-humidity air flows from the through hole provided in the washing and dewatering tank 3 to the outer tank 2, is sucked into the drying duct 29 from the suction port 2a, and flows from the bottom upward in the drying duct 29 (arrow 42: 2~ Figure 5). On the wall surface of the drying duct 29, the cooling water from the water-cooling dehumidification mechanism flows, and the high-temperature and humid air is cooled and dehumidified by contact with the cooling water to become a dry low temperature. Air enters the filter conduit 27 (arrow 43: Figures 2 to 5). The yarn is removed by the mesh filter 8a provided in the filter duct 27, enters the intake duct 33, and is sucked into the blower unit 28 (arrow 44: Fig. 2). Then, the heater 31 is again heated and blown into the washing and dewatering tank 3, and thus circulated. In the meantime, the washing and dewatering tank 3 is rotated forward and backward at a low speed to lift the laundry to the vicinity of the nozzle 32d, and the high-speed warm wind directly hits the laundry.

In this way, it is possible to remove the wrinkles of the wrinkles of the clothes in such a manner that the high-speed warm air is ejected to the clothes. However, in the case of the configuration shown in Figs. 1 to 7, it is effective to dry the wet clothes immediately after washing, and the clothes are dried after a certain period of time after washing, or are dried. When the wrinkles on the clothes are flattened, the removal of the wrinkles is incomplete.

In the present embodiment, the drum type washing and drying machine having the configuration shown in Figs. 1 to 7 is further provided with an improved structure.

Hereinafter, the configuration added will be described with reference to Figs. 8 to 14 . In FIGS. 8 to 14, the same portions as those shown in FIGS. 1 to 7 are denoted by the same reference numerals.

As described with reference to FIGS. 1 to 7, during the drying operation, the blower unit 28 is operated to blow high-speed warm air into the washing and dewatering tank 3. In the drying operation, when a predetermined mode (steam iron stroke) is set, a predetermined period of time at the start of the drying operation is configured, and mist-like (mist-like) water can be supplied to the high-speed warm air. The composition of the high-speed warm air is blown into the washing and dewatering tank 3 in detail. 1 to 7 illustrate the same configuration.

Fig. 8 is a view showing the inside of a drum type washing and drying machine of the embodiment of the present embodiment from the top surface. That is, the frame 1 of the drum type washing and drying machine shown in Fig. 1 is taken out and viewed from the top surface.

As shown in FIG. 1, the air blowing unit 28 used in the drying operation is configured to supply water from the water supply unit 50 to the air supply unit 28 via the switching valve 51 and the mist joint 53. The air is sent to the curved portion 70 of the warm air duct 30 in the washing and dewatering tank 3. A heater (not shown) is disposed in (or in the vicinity of) the air blowing unit 28, and is configured to heat the wind generated by the air blowing unit 28 to a high temperature. The switching valve 51 is a valve that switches the destination of the water supply between the cooling water supply pipe 52 and the mist joint 53. When the switching valve 51 is cut to the mist joint 53 side, water from the water supply unit 50 is supplied to the curved portion 70 constituting the warm air duct 30. When the switching valve 51 is cut to the cooling water supply pipe 52, it is supplied as cooling water necessary for the drying operation.

9 to 12 are views showing the configuration of the curved portion 70 of the warm air duct 30. As shown in Fig. 6, the high-pressure and high-temperature wind generated by the air blowing unit 28 is guided to the warm air duct 30, as shown in Fig. 6 and Fig. 7, through the rubber bellows tube 30a and the bellows joint 30b. It is supplied to the washing and dewatering tank 3.

Here, as shown in FIG. 9 and FIG. 10, the curved portion 70 of the warm air duct 30 is attached to the end of the bellows pipe 30a, and the warm air W that is conveyed in the horizontal direction from the air blowing unit 28 in the warm air duct 30 is bent. On the lower side, it becomes the structure of the bellows tube 30a and the bellows joint 30b which are sent to the lower side. to make. Thereby, the warm air W from the air blowing unit 28 is caught on the curved inner wall 71 of the curved portion 70. The bent portion 70 is, for example, a member formed of a synthetic resin.

The mist nozzle 54 supplies water from the water supply unit 50 to the downstream side of the heater and is the upstream side of the nozzle 32d.

A cross section of the curved portion 70 is shown in Fig. 11 . As shown in Fig. 11, the mist nozzle 54 extends from the end portion 54a to the vicinity of the center of the vicinity of the curved inner wall 71 of the tube constituting the curved portion 70, and is supplied from the end portion 54a into the warm air duct 30. Fig. 12 is a view showing a modification of Fig. 11, and as shown in Fig. 12, it is preferable to supply water from the side surface portion 54b of the mist nozzle 54 to the warm air duct 30. Alternatively, it is preferable to supply water from the tip end portion 54a and the side surface portion 54b of the mist nozzle 54 to the warm air duct 30.

As described above, the tube constituting the curved portion 70 is supplied with high-pressure and high-temperature air from the air blowing unit 28. Therefore, the water supplied into the tube from the distal end portion 54a of the mist nozzle 54 flows down the wall surfaces of the flow paths 32b and 32c of the warm air duct 30 and the warm air outlet 32, and is supplied together with the high-speed wind from the nozzle 32d. Go to the washing and dewatering tank 3. At this time, since the air in the washing and dewatering tank 3 around the nozzle 32d has a high speed difference, the water is strongly stirred by the speed difference, diffused by the microparticles, and diffused to form a mist and a high-speed wind. One piece is supplied to the outer tank 2 and the washing and dewatering tank 3.

Further, as the air blowing unit 28 is interposed between the bending portions 70, The wind that is sent to the washing and dewatering tank 3 by the bellows pipe 30a and the bellows pipe joint 30b is in the nozzle 32d of the warm air blowing port 32, and is, for example, a high-speed wind having a wind speed of 50 m/s or more.

Fig. 20 is a perspective view showing a piping connecting portion of the circulation pump and the filter case. Figure 21 is a perspective view showing the internal shape of a casing of a circulation pump. Fig. 22 is a perspective view showing a moving wheel of the circulation pump.

First, the circulation structure of the washing water will be described. The drum type washing and drying machine of the present embodiment is provided with a circulation pump 124 as shown in Figs. 15 and 19 . The circulation pump 124 sucks the water stored in the outer tank 2 through the hose 122 and sends it to the upper portion of the outer tank 2 through the circulation hose 127. A filter case 123 is provided between the circulation pump 124 and the hose 122, and the yarn or the like is collected from the circulating washing water. That is, the hose 122 is communicated to the filter case 123, and the outlet of the filter case 123 is communicated to the circulation pump 124. Further, the hose 122 is constructed of a bellows tube.

Here, the circulation structure of the washing water will be described in detail with reference to FIGS. 15 and 20 to 22 . In the washing process, the washing water is circulated by using the circulation structure of the washing water, and the washing effect and the washing effect are improved by spraying water to the clothes or the like.

On the back side of the bottom of the filter case 123, a water inlet 123a, a water outlet 123b, and a suction port 143 of the circulation pump 124 are provided. The drain port 21 of the outer tub 2 and the water inlet 123a are connected by a hose 122, and the drain valve 125 and the water outlet 123b are connected by a hose 149. Further, the drain hose 125 is connected to the drain valve 125, and the washing water is drained to the outside of the machine. Further, Fig. 4 shows a simplified configuration in which the drain hose 26 is directly connected to the drain port 21.

The circulation pump 124 is composed of a casing 142, a moving wheel 150, and a circulation pump motor 147. The case 142 is integrally formed with the filter case member 123, and has a suction port 143 at a central portion of the side wall 142a of the case 142. On the inner peripheral surface of the casing, the discharge port A144a and the discharge port B145a-package partition walls 146a and 146b are opened, and the discharge port A144 and the discharge port B145 are individually connected. The inner sides of the partition walls 146a, 146b are connected to the casing side wall 142a. Further, the discharge enthalpy side wall faces of the partition walls 146a and 146b are almost perpendicular.

The moving wheel 150 is mounted on the shaft of the circulation pump motor 147. The movable wheel 150 forms a cross-shaped blade 150a, 150b. When the driven wheel 150 is rotated to the left (hereinafter referred to as a positive rotation), the water flowing in from the suction port 143 is pushed out toward the inner peripheral wall of the casing 142 by the pumping action by the centrifugal force of the moving wheel 150. The case 142 flows while rotating rightward, but collides with the partition wall 146a in which the gap between the case and the blade is narrowed in the radial direction, The flow direction changes and flows out from the spout 埠A144a. When the rotor 150 rotates to the left (hereinafter referred to as reverse rotation), the water collides with the partition 146b and flows out of the discharge port B145a. In this way, the direction in which the pump is rotated can be changed without changing the switching mechanism of the special flow path.

A plurality of protrusions 142b are formed on the outer peripheral portion of the casing 142, and the protrusions 142b are inserted into the annular slits 148b of the circulation pump base 148 to rotate the casing 142 to set the protrusions 142b on the circulation pump base. The latch portion 148 of the 148 is pressed to fix the case 142.

The discharge port A144 is connected to the circulation hose 127 attached to the outer peripheral wall of the front side of the outer tank cover member 2d via the bellows tube C141. The circulation hose 127 is connected to a nozzle 127a provided on the upper side of the outer tank cover member 2d (see Fig. 16). The nozzle 127a is formed by expanding the water into a film shape in the horizontal direction (for example, a slit shape), and sprinkling the washing water from the front side into the washing and dewatering tank 3.

The discharge port B145 is connected to the inflow port 118 of the recessed portion 24 provided at the bottom of the outer tub 2 via the bellows tube D140.

When the circulation pump 124 is rotated in a state where the drain valve 125 is closed, the washing water in the outer tub 2 passes through the hose 122 from the drain port 21, and the foreign matter is removed by the filter 123c housed in the filter case 123, and the circulation is entered. The pump 124 is discharged from the discharge port A144, and is sprayed from the nozzle 127a into the washing and dewatering tank 3 through the circulation hose 127.

When the circulation pump 124 is reversely rotated, the washing water in the outer tank 2 passes through the hose 122 from the drain port 21, and the foreign matter is removed by the filter 123c, enters the circulation pump 124, is discharged from the discharge port B145, and is returned from the inlet 118. Loop into the outer tank 2 (the flow is indicated by a thick arrow in 17).

When the drain valve 125 is opened, the washing water in the outer tub 2 passes through the drain valve 125 from the discharge port B145 through the filter 123c, and is drained from the drain hose 26 to the outside of the machine.

Next, the dissolution of the detergent will be explained.

In association with the dissolution of the detergent, as shown in Fig. 18, a concave recessed portion 24 is provided in the axial direction at the lowest portion of the peripheral wall of the outer tub 2. The bottom surface of the recessed portion 24 is an inclined surface that descends from the front side to the rear side, and a drain port 21 is provided at the lowermost portion of the rear side of the recessed portion 24. The drain hose 122 is connected to the drain port 21. An inflow port 118 for circulating water at the bottom is provided on the front side of the concavity portion 24. Further, the upper portion of the recessed portion 24 has a partition wall 2b continuous from the inner peripheral surface of the outer peripheral wall of the outer tub 2, and covers a width of a half of the recessed portion 24. The partition wall 2b is oriented in a direction opposite to the direction of rotation when the washing and dewatering tank 3 is dehydrated. The drain port 21 and the inflow port 118 are provided at positions shifted from the center in the width direction of the recessed portion 24 by the rotation direction of the washing and dewatering tank 3. To this end, the partition wall 2b is provided in the upper portion of the drain port 21 and the inflow port 118.

In the present embodiment, the circulation pump motor 147 is energized to cause the circulation pump 124 to rotate in the reverse direction to dissolve the detergent. The detergent to be supplied to the detergent tray 7 flows by the water supplied from the water supply solenoid valve 16 or the bath water supply pump 17, and passes through the bellows tube 120 and the bellows tube 120 and the outer tub 2 shown in FIG. The connecting flow path portion 25 flows down to the concave portion 24. When the circulation pump motor 147 is energized, the water and the detergent stored in the bottom of the outer tank 2 and the recessed portion 24 pass through the hose 122 and the filter from the drain port 21. 123c enters the casing 142 from the suction port 143. Then, it is discharged from the discharge port B145, and is returned to the concave portion 24 from the inflow port 118 through the bellows tube D40 for circulation. The detergent is stirred and dissolved by the blades 150a, 150b of the moving wheel 150 to produce a washing water having a high detergent concentration. The time for the detergent to dissolve is within 1 minute to 2 minutes.

The flow direction when flowing out from the inflow port 118 toward the concavity portion 24 is upward, but hits the partition wall 2b, and the flow direction is changed to the drain port 21 side (the thick arrow in Fig. 5). For this reason, even when water containing a detergent which is not dissolved in the initial stage of detergent dissolution is circulated, it is possible to prevent the undissolved detergent from directly flowing into the washing tank 3. However, a part of the water that has hit the partition 2b flows to the side of the outer tank cover 2d. When there is a flowing retained portion on the side of the outer tank cover 2d, there is a fear that undissolved detergent is deposited in the portion. Here, it is preferable to provide a rectifying member that reliably guides the water returning to the concavity portion 24 to the side of the drain port 21.

The filter 23c is a lattice-shaped filter and does not accumulate the passed undissolved powder detergent.

When the detergent is dissolved (the circulation pump 124 is in the reverse rotation), the pressure of the discharge port A144a is greatly lower than the pressure of the discharge port B145a due to the action of the partition wall 146b, and the water or the undissolved detergent does not. The nozzle 127a runs into the washing and dewatering tank 3. However, there is an undissolved detergent running on the way of the bellows tube C141 or the circulation hose 127. Here, the circulation pump 124 is temporarily stopped during the dissolution of the detergent. When the circulation pump 124 is stopped, the undissolved detergent immersed in the bellows tube C141 or the circulation hose 127 is returned to the casing 142. Then, to re-run the circulation pump 124 The way you can eliminate undissolved detergent. The temporary stop of the circulation pump 124 is performed three to four times in the dissolution of the detergent. Moreover, it is sufficient that the stop time of the circulation pump 124 is within 1 second.

Next, the washing procedure relating to the present embodiment will be described in detail using Figs. 23, 24 and 25. Fig. 23 is a flowchart showing the flow of the operation of the washing program. Fig. 24 and Fig. 25 are diagrams showing the spreading procedure for dispersing the washing water and the warm air (hereinafter referred to as warm air mist) containing the atomized moisture in the washing program. A program diagram of the mist program in the dewatering tank 3. Further, Fig. 25 is carried out in conjunction with Fig. 24.

The piping system including the circulation pump 124 and the circulation hose 127 and the water sprinkling nozzle 127a constitutes a high-concentration detergent that supplies a high-concentration detergent solution (washing water having a high detergent concentration) to the washing and dewatering tank 3. Solution supply device. The high-concentration detergent solution supply device is a device for dispersing washing water having a high detergent concentration in clothes and the like in the washing and dewatering tank 3, and may be referred to as a washing water dispersing device or simply as a sprinkling device.

The selected program is executed from the washing program, the washing program, the dehydration program, and the drying program by selecting and setting the stroke for washing and drying by the user. In Fig. 23, the case where the washing program, the washing program, and the dehydrating program are selected will be described. In addition, the "action" such as the detergent dissolving action, the dispersing action, the fog action, and the washing action can also be used as a "program", but in order to avoid confusion with the "program" in the washing process (especially the confusion between the washing process and the washing action) ) is described as "action".

In the washing program, a detergent dissolution operation, a scattering operation, a mist blowing operation (indicated as fog), and a washing operation are performed. Hereinafter, the mist blowing operation is referred to as a fog motion. In the detergent dissolving operation, washing water (hereinafter referred to as a high-concentration detergent solution) in which the detergent is dissolved in water in a state in which the concentration is higher than a predetermined concentration is generated. In the spreading action, the high-concentration detergent solution is spread to clothes and the like. In the mist blowing action, the warm air mist is blown into the washing and dewatering tank 3. In the washing operation (washing operation), mechanical force is applied to the clothes and the like to be washed. When the washing program is finished, proceed to the cleaning program.

Further, in the present embodiment, a drum type washing and drying machine will be described, but it is also applicable to a vertical type washing and drying machine in which the rotating shaft of the washing and dewatering tank is provided in the vertical direction. In the drum type washing and drying machine, a mechanical force is applied to the clothes and the like by the washing and dewatering tank 3 in the washing operation. In the vertical washing and drying machine, the pulsator provided in the washing and dewatering tank causes the water flow to impart mechanical force to the clothes or the like, or the rotating disk provided in the washing and dewatering tank is rotated to directly apply the machine to the clothes and the like. The method of force, etc.

In the washing process, first, drainage and dehydration of the washing water from the outer tank 2 are performed. Thereafter, the washing water is stored in the outer tank 2, or the washing operation is performed while the water is flushed with the washing water. It is also possible to carry out a cleaning operation while storing water and washing water while storing the washing water. Further, drainage and dehydration of the wash water may also be included in the washing process. After the cleaning process and the cleaning action, drainage and dehydration are performed. After draining and dehydrating, the cleaning operation is repeated for the set number of times. When the next cleaning operation is performed after the cleaning operation, drainage and dehydration are performed between the cleaning operation and the next cleaning operation. When the final cleaning operation is completed, proceed to the dehydration program.

The washing operation in the washing program is carried out by applying mechanical force to the clothes or the like by rotating the washing and dewatering tank 3 in a drum type washing and drying machine. In the vertical washing and drying machine, the pulsator provided in the washing and dewatering tank is used to generate a mechanical force while applying a mechanical force to the clothes or the like, or the rotating disk provided in the washing and dewatering tank is directly rotated. A method in which a mechanical force or the like is applied to a garment or the like.

In the dehydration process, the drainage of the washing water is performed, and the dehydration operation is performed. The dehydration operation is a drum type washing and drying machine, and the vertical type washing and drying machine is also suitable for both sides to rotate the washing and dewatering tank at a high speed. Furthermore, the drainage of the washing water can also be carried out in the washing process.

Next, the scattering operation and the mist blowing operation in the washing process will be described in detail.

When the above-described detergent dissolution operation is completed, the scattering operation shown by the operation symbol <A> is performed in Fig. 24 . In this spreading operation, the circulation pump 124 was turned on, and the circulation pump 124 was operated at 2,800 rpm. The spreading operation is a procedure of sprinkling a high-concentration detergent solution from the sprinkling nozzle 127a to clothes, etc., for 25 seconds. In the present operation, the water supply (water supply valve) due to the rotation of the drum and the water supply valve, the rotation of the motor 28a of the blower fan unit 28 (the rotation of the blower fan), and the heater 31 for the warm air are all stopped.

After the scattering operation indicated by the motion symbol <A>, the fog motion (fog A motion) indicated by the motion symbol <B> is performed within approximately three minutes. In this fog action, while rotating the drum in a certain direction (CW direction), The water from the faucet 61 flows through the water supply solenoid valve 62, the cooling joint 63, and the second switching valve 51 to the mist joint 53 and is supplied into the warm air duct 30. Regarding the water supply due to this route, the column of the water supply valve is referred to as "cooling water valve". In this action, the cooling water valve is continuously opened. Further, in this operation, the blower fan rotation and the warm air heater 31 are turned on, and the water supplied to the warm air duct 30 is atomized by the warm warm air, and is blown into the washing and dehydrating tank 3 Inside. Further, in this operation, the circulation pump 124 is turned off, and the dispersion of the washing water is stopped.

In this operation, the rotation of the drum and the rotation of the blower fan are changed in accordance with the amount of the clothes or the like. When the amount of rotation of the drum is set to be larger, the number of revolutions (rotation speed) is higher, and the operation time is increased. In the present embodiment, the amount of the laundry or the like is divided into three stages, and when the amount of the laundry or the like is large, the number of revolutions (rotation speed) is 40 rpm, the opening is performed within 30 seconds, and the closing is performed within 5 seconds. When the amount of clothes or the like is intermediate (medium), the number of revolutions (rotation speed) is 35 rpm, the opening is performed within 10 seconds, and the operation is turned off within 15 seconds. When the amount of clothes or the like is small, the number of revolutions (rotation speed) is 30 rpm, the opening is performed within 5 seconds, and the operation is turned off within 15 seconds. When the amount of the clothes or the like is large, the number of revolutions (rotation speed) of the fan is increased as compared with the case where the amount of the clothes is large. In the present embodiment, when the amount of clothes or the like is large and the middle (medium) is used, the number of revolutions (rotation speed) of the fan is operated at 7000 rpm, and when the amount of clothes or the like is small, the number of revolutions of the fan (rotation speed) is used. ) Operates at 5800 rpm.

Fig. 26 shows the characteristics of the number of revolutions of the blower fan and the amount of air blown from the air outlet. Fig. 27 shows the characteristics of the number of revolutions of the blower fan and the wind speed of the blower outlet. When the number of revolutions (rotation speed) of the fan is 5800 rpm, the air volume of the air outlet is about 0.58 m ³ /min, and the wind speed of the air outlet is about 37 m/s. Further, when the number of revolutions (rotation speed) of the fan was 7000 rpm, the air volume of the air outlet was about 0.73 m ³ /min, and the wind speed of the air outlet was about 44 m/s. The air volume and the wind speed in the fog program are set to be small with respect to the air volume and the wind speed of the warm air in the drying program. By suppressing the number of revolutions (rotation speed) of the fan, it is possible to suppress the intrusion of the bubble generated by the high-concentration detergent solution into the drying duct 29, or the bubble that has entered the drying duct 29 rises in the drying duct. 29 inside the situation. In addition, when the amount of the clothes or the like is small, the effect of suppressing the intrusion of the bubble or suppressing the rise of the bubble can be improved by suppressing the reduction in the number of revolutions (rotation speed) of the fan as compared with the case of a large number of cases.

In the fog action, the water is atomized to cause it to be applied to the clothes, etc., and a small amount of water can be used to make the clothes and the like completely wet. For this reason, it is possible to saturate the clothes or the like without diluting the high-concentration detergent solution to more than necessary. Further, the mist acts on the clothes and the like together with the warm wind, and the temperature of the clothes and the like can be increased by the warm air, and the effect (enzyme power) of the enzyme held by the detergent can be improved. Therefore, the cleaning effect by the high concentration detergent solution can be improved via the warm air mist. Further, the warm air mist can simultaneously perform the operation of making the clothes wet and the like after the water supply and the operation of increasing the temperature of the clothes, etc., and the time required for the washing process or the washing process can be shortened.

After the fog A operation, the scattering operation (scattering A motion) indicated by the motion symbol <C> is performed within 10 seconds. Similarly to the operation of the mist A, the circulation water pump 124 is opened while continuously opening the cooling water valve while supplying water. The circulation pump 124 is operated at 2800 rpm.

After the A motion is distributed, the fog motion (fog B motion) indicated by the motion symbol <D> is performed within 3 minutes. In the case where the amount of laundry or the like is small in this operation, the water supply due to the cooling water valve is repeatedly turned on within 3 seconds, and the operation is turned off within 40 seconds. That is, the water supply due to the cooling water valve is intermittently performed. Thereby, the amount of water supply in the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned. The other operations are the same as the fog A action.

After the fog B operation, the scattering operation (spreading B motion) indicated by the motion symbol <E> is performed within 10 seconds. In the case where the amount of laundry or the like is small in this operation, the water supply (closing) due to the cooling water valve is not performed. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned. The other operations are the same as the scatter A action.

After the B motion is distributed, the fog motion (fog C motion) indicated by the motion symbol <F> is performed within 3 minutes. In this operation, when the amount of clothes or the like is intermediate, the water supply due to the cooling water valve is turned on within 3 seconds, and the operation is stopped within 40 seconds, and the amount of clothes and the like is small. The difference in the supply of water (closed) due to the cooling water valve is different. The other operations are the same as the fog B operation. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned.

After the operation of the mist C, as shown in FIG. 25, the scattering operation (spread C operation) indicated by the operation symbol <G> is performed within 10 seconds. In this operation, when the amount of clothes or the like is intermediate with respect to the spread B operation, the water supply (closed) due to the cooling water valve is not different. of. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned. The other operations are the same as the scatter B action.

After the C motion is distributed, the fog motion (fog D motion) indicated by the motion symbol <H> is performed within 1 minute. In this operation, when the amount of clothes or the like is intermediate with respect to the operation of the mist C, it is different that the water supply (closing) due to the cooling water valve is not performed. The other operations are the same as the fog C operation. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned.

After the fog D operation, the scattering operation (scattering D operation) indicated by the operation symbol <I> is performed within 10 seconds. This operation performs the same operation as the scatter C operation.

After the D motion is distributed, the fog motion (fog E motion) indicated by the motion symbol <J> is performed within 6 minutes. The content of this operation is the same as the content of the fog C operation.

After the fog E operation, the scatter action (spreading E action) indicated by the action symbol <K> is performed within 10 seconds. In this operation, when the amount of clothes or the like is large with respect to the distributed D operation, the water supply (closing) due to the cooling water valve is not different. That is, in this operation, regardless of the amount of clothes or the like, the water supply due to the cooling water valve is not performed. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned. The other operations are the same as the scatter D action.

After the E motion is dispersed, the fog motion (fog F motion) indicated by the motion symbol <L> is performed within 6 minutes. In this operation, when the amount of clothes or the like is large with respect to the fog E operation, the water supply in the cooling water valve is repeatedly applied. Turn on within 3 seconds and turn off within 40 seconds. The other operations are the same as the fog E operation. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned.

After the fog F operation, the scattering operation (spreading F operation) indicated by the operation symbol <M> is performed within 10 seconds. This operation performs the same operation as the K motion.

After the F operation is spread, the fog motion (fog G motion) indicated by the motion symbol <N> is performed within 6 minutes. This operation is performed in the same operation as the fog F operation.

As described above, in the scattering operation (dispersion program: first program) and the mist operation (fog program: second program), the water supply due to the cooling water valve is performed, and the water is washed in the high-concentration detergent solution. The concentration of detergent is reduced. For this reason, the water supply due to the cooling water valve is intermittently performed from the reverse spread operation and the mist operation, and the water supply due to the cooling water valve is not performed at once. Further, if the amount of clothes or the like is smaller, the amount of water supply in the scattering operation and the mist operation can be reduced, and the water supply due to the cooling water valve is intermittently performed at one time, and the cooling water valve is not caused at all. The timing of the water supply is earlier than when the amount of clothing or the like is large. Thereby, the amount of water supplied by the cooling water valve is suppressed, and the high-concentration detergent solution can be prevented from being thinned.

In the mist operation, while the washing and dewatering tank 3 is rotated, the warm air mist is blown into the washing and dewatering tank 3. Thereby, the warm wind mist can be applied to the clothes and the like. In this case, the rotation speed of the washing and dewatering tank 3 is 30 to 40 rpm, which is equivalent to the rotation speed used in the washing program. The The rotation speed is the rotation speed at which the washing effect can be obtained in the washing process. That is, it is possible to prevent clothes or the like from sticking to the inner wall of the washing and dewatering tank 3. For this reason, the warm wind mist can be applied to clothes and the like.

In the above-described embodiments, each of the scatter operation and the fog action is intermittently performed, that is, the scatter action and the fog action are alternately performed. On the other hand, the scattering operation and the fogting operation can be performed at least at the same time. Of course, it is also possible to completely overlap the spreading action and the fog action.

As the warm air heater (heating device) 31, a PTC heater can be used. By using the PTC heater, the amount of air can be increased, and the amount of heat applied to clothes or the like can be increased. In addition to the PTC heater, a heat pump can also be used as the heating means for the air. Further, in the present embodiment, the heater 31 used in the drying process may be used for the mist operation, and the heater (heat source) used in the drying process may have another heat source. Further, the heat source that is not used in the drying process means that the washing machine can be operated even in a washing machine that does not have a drying function.

In the present embodiment, in order to blow a warm air mist into the washing and dewatering tank 3, the drying duct 29 is used. The drying duct 29 is extended upward from the intake port 2a, and a heater 31 is provided on the downstream side. When the drum type washing and drying machine is viewed from the back side, as shown in FIG. 3, the intake port 2a is located on the lower left side of the outer tub 2 with respect to the center of rotation of the washing and dewatering tank 3. Further, the drying duct 29 is positioned on the left side of the outer tub 2 with respect to the center of rotation of the washing and dewatering tank 3. In this case, when the washing and dewatering tank 3 rotates clockwise (right-handed), the bubble that moves in accordance with the rotation of the washing and dewatering tank 3 is extended upward from the air inlet 2a. The drying duct 29 is easily moved into the drying duct 29 because it moves in the extending direction. On the other hand, when the washing and dewatering tank 3 rotates counterclockwise (left-handed), the bubble which moves with the rotation of the washing and dewatering tank 3 moves in the opposite direction to the extending direction of the drying duct 29, It is difficult to invade the drying duct 29. The heater 31 is provided on the downstream side of the drying duct 29, and it is desirable that the bubble is difficult to reach the structure of the heater 31. In the present embodiment, the washing and dewatering tank 3 is provided with a portion on the side of the intake port 2a and the drying duct 29 with respect to the center of rotation, and is oriented in a direction in which the drying duct 29 is extended (from the suction port 2a disposed below) The direction upwards is rotated in the opposite direction.

In other words, the air intake port 2a is disposed in the outer groove 2 so as to be at the one side in the left-right direction with respect to the center of rotation of the air intake port 2a, and the rotation center is at a lower position than the center of rotation; The water nozzle 127a supplies the warm air and the tap water that has flowed to the warm air to the washing and dewatering tank, and the drying duct 29 is disposed on one of the left and right sides with respect to the rotation center. The intake port 2a extends upward to connect the intake port 2a and the sprinkling nozzle 127a; in the fog operation (fog program: second program), the washing and dewatering tank 3 is rotationally driven in one of the directions so that the relative One of the left and right sides of the rotation center is rotated in the opposite direction (from the top to the bottom) in the direction in which the drying duct 29 extends.

In FIGS. 24 and 25, the rotation of the drum during the fog operation is rotated in one of the clockwise directions (CW). Further, the direction in which the drums of FIGS. 24 and 25 are rotated is viewed from the front side of the drum type washing and drying. In the case of the machine, the clockwise direction (CW: right-handed) shown in Figs. 24 and 25 coincides with the counterclockwise direction (left-handed) when the drum type washing and drying machine is viewed from the back side.

Next, another embodiment of the present invention will be described using the drawings. In addition, the configuration of the washing and drying machine (FIG. 1 to FIG. 22) and the flow of the operation of the washing program (FIG. 23) are the same as those of the first embodiment described above, and the description thereof is omitted. Further, here, the case where the room temperature and the water temperature are about 20 ° C will be described.

FIG. 28 and FIG. 29 are diagrams showing the scattering procedure for dispersing the washing water and the atomizing procedure for blowing the warm mist containing the atomized moisture into the washing and dewatering tank 3, which is carried out in the washing program. Program diagram. Figure 29 is a continuation of Figure 28 implementation. The feature of this embodiment is that the temperature of the mist is higher than that of the first embodiment, and the temperature of the laundry is increased more efficiently, and the detergency is further improved.

In Fig. 23, when the detergent dissolution program is completed, the scattering operation shown by the operation symbol <A> in Fig. 28 is the same as that of the first embodiment.

After the spreading operation indicated by the operation symbol <A>, the warm-up operation indicated by the operation symbol <B> is performed within 3 minutes. In the preheating operation, while the drum is rotated in one direction (CW direction), the blower fan is rotated and the warm air heater 31 is turned on, and the warm air is blown from the warm air blowing port 32 into the washing and dehydrating tank 3. As a result, the temperature of the laundry and the like in the washing and dewatering tank 3 rises, and the temperature of the wall surface of the warm air flow path from the warm air heater 31 to the warm air blowing port 32 also rises. The preheating action time is set within 3 minutes because the temperature of the wall surface of the aforementioned warm air flow path reaches about 3 minutes. Full temperature of 60 ° C. Further, in this operation, the circulation pump 124 is turned off, and the dispersion of the washing water is stopped.

In this operation, the rotation of the drum and the rotation of the blower fan are changed in accordance with the amount of the clothes or the like. When the amount of rotation of the drum is set to be larger, the number of revolutions (rotation speed) is higher, and the operation time is increased. In the present embodiment, the amount of the laundry or the like is divided into three stages, and when the amount of the laundry or the like is large, the number of revolutions (rotation speed) is 40 rpm, the opening is performed within 30 seconds, and the closing is performed within 5 seconds. When the amount of clothes or the like is intermediate (medium), the number of revolutions (rotation speed) is 35 rpm, the opening is performed within 10 seconds, and the operation is turned off within 15 seconds. When the amount of clothes or the like is small, the number of revolutions (rotation speed) is 30 rpm, the opening is performed within 5 seconds, and the operation is turned off within 15 seconds. When the amount of the clothes or the like is large, the number of revolutions (rotation speed) of the fan is increased as compared with the case where the amount of the clothes is large. In the present embodiment, when the amount of clothes or the like is large and the middle (medium) is used, the number of revolutions (rotation speed) of the fan is operated at 7000 rpm, and when the amount of clothes or the like is small, the number of revolutions of the fan (rotation speed) is used. ) Operates at 5800 rpm.

After the warm-up operation, the scattering operation (scattering motion A) indicated by the motion symbol <C> is performed within 10 seconds. The circulation pump 124 is turned on and the circulation pump 124 is operated at 2800 rpm. This operation is for re-impregnating the high-concentration detergent liquid that has flowed out of the concave portion 24 stored in the outer tub 2 from the clothes or the like to the clothes or the like after the laundry is soaked in the scattering operation.

After the A motion is distributed, the fog motion (fog A motion) indicated by the motion symbol <D> is performed within 3 minutes. In this action, the water supply caused by the cooling water valve is turned on within 1.5 seconds and closed within 40 seconds. Running. That is, the water supply due to the cooling water valve is intermittently performed. At this time, the wall surface of the warm air flow path is about 60 ° C due to the preheating operation, and the water flowing down the wall surface is warmed, and the mist which is changed from 35 ° C to 40 ° C is discharged to the clothes. The intermittent supply of mist is to maintain the temperature of the mist from 35 at 40 °C. Further, the warm air is blown from the nozzle 32d from 60 ° C to 70 ° C, and the temperature at the time of hitting the laundry is changed from 40 ° C to 50 ° C. In the present mist operation, it is possible to further atomize a small amount of water to make the clothes and the like completely wet compared to the first embodiment, and it is possible to suppress the decrease in the concentration of the high-concentration detergent solution to the minimum to allow the laundry to penetrate. Further, the mist which is heated from 35 ° C to 40 ° C is applied to the clothes and the like together with the warm air from 40 ° C to 50 ° C, so that the temperature of the clothes or the like can be raised earlier, and the detergent contained in the detergent can be improved. The effect of the enzyme (which is activated from about 30 ° C to 40 ° C). In addition, in this operation, the rotation of the drum and the rotation of the blower fan are changed in accordance with the amount of the clothes or the like, and the same as the warm-up operation, and detailed description thereof will be omitted.

After the fog A operation, the scatter operation (spread B action) indicated by the action symbol <E> is performed within 10 seconds, but the action system is the same as the scatter A action.

After the B motion is spread, the fog motion (fog B motion) indicated by the motion symbol <F> is performed within 1 minute. In this operation, when the amount of clothes or the like is small with respect to the operation of the mist A, it is different that the water supply due to the cooling water is not performed (the cooling water valve is closed). The other operations are the same as the fog A operation. Thereby, even in the case of a small amount of laundry or the like having a small water content, it is possible to prevent the high-concentration detergent solution from being thinned.

After the fog B action, as shown in FIG. 29, the action is recorded. The scatter action (spread C action) indicated by the number <G> is within 10 seconds, but the action is the same as the scatter A action.

After the C motion is distributed, the fog motion (fog C motion) indicated by the motion symbol <H> is performed within 3 minutes. In this action, the cooling water valve is continuously opened. In the high-concentration detergent solution in which the clothes are soaked in the scattering operation, it is not necessarily uniformly permeated, and the distribution of the soaking condition is improved by the subsequent fog A operation or the fog B operation, especially when the amount of clothes or the like is large. There are not enough situations. When the penetration of the high-concentration detergent solution is not uniform, the washing performance may be uneven. Therefore, the spray is continuously sprayed to the clothes, and the high-concentration detergent solution is uniformly permeated into the clothes or the like. In the warm-up operation, the mist A operation, and the fog B operation, the temperature of the wall surface of the warm air flow path from the warm air heater 31 to the warm air blowing port 32 or the temperature of the outer tank cover 2d rises, and even if the mist is continuously dispersed, the temperature of the mist is At about 30 ° C, it is an activity that does not hinder the enzyme contained in the detergent. Further, when the amount of clothes or the like is small, the water supply due to the cooling water is not performed (the cooling water valve is closed). In this case, when the amount of the laundry or the like is small, the high-concentration detergent solution is uniformly distributed to the clothes or the like under the scattering operation, and the concentration of the high-concentration detergent solution is prevented from becoming thin.

After the fog C is operated, the scatter operation (scatter D operation) indicated by the operation symbol <I> is performed within 10 seconds, but the operation is the same as the scatter A operation.

After the D motion is spread, the fog motion (fog D motion) indicated by the motion symbol <J> is performed within 6 minutes. In this action, when the amount of clothes or the like is large, the water supply due to the cooling water is repeatedly turned on within 1.5 seconds. The operation is stopped within 40 seconds, and when the amount of laundry or the like is intermediate or small, the water supply due to the cooling water valve is not performed (the cooling water valve is closed). Thereby, the supply amount of the mist is suppressed, and the high-concentration detergent solution can be prevented from being thinned. The other operations are the same as the fog A operation.

After the fog D operation, the scattering operation (scattering E motion) indicated by the motion symbol <K> is performed within 10 seconds, but the motion system is the same as the scatter A motion.

After the E operation is performed, the fog operation (fog E operation) indicated by the operation symbol <L> is performed within 6 minutes, but the operation is the same as the fog D operation.

After the fog E operation, the scatter action (spread F action) indicated by the action symbol <M> is performed within 10 seconds. This operation performs the same operation as the scatter A action.

After the F operation is spread, the fog motion (fog F motion) indicated by the motion symbol <N> is performed within 6 minutes. This operation is performed in the same operation as the fog D operation.

After the fog F operation, a washing operation (washing operation) is performed. In this operation, after the water level from the water supply to the washing operation is completed, mechanical force is applied to the clothes and the like, and the washing process is terminated, and then the washing program and the dehydration program are executed.

Further, in the present embodiment, the water supply flow rate of the cooling water valve is about 0.3 liters. In the warm air mist shower program shown in Figs. 28 and 29, a total of about 1.1 liters of mist heated from 30 ° C to 40 ° C was supplied between about 30 minutes. Through this, when the fog action F ends The temperature of the clothes and the like is 35 ° C to 40 ° C, which is the temperature at which the enzyme contained in the detergent is most activated. Further, the water temperature of the washing water during the washing operation is about 30 ° C, which is a temperature at which the surfactant or the enzyme of the detergent sufficiently moves.

As described above, the temperature of the wall surface and the flow path member constituting the flow path through which the warm air flows is increased by the preheating operation, and the water supply due to the cooling water is intermittently performed in the mist operation. It is possible to warm the clothes with warmed mist and warm air, and the effect of the enzyme contained in the detergent can be made from an earlier stage. Further, by suppressing the supply amount of the mist to the minimum necessary, the high-concentration detergent solution can be uniformly impregnated into the clothes or the like while suppressing the decrease in the concentration of the high-concentration detergent solution.

In the conventional method of cleaning the temperature of the washing water, a heater is provided at the bottom of the outer tank, and the whole of the washing water stored in the outer tank is heated while being warmed. On the other hand, in the present embodiment, the amount of water used for dissolving the detergent and the amount of water supplied to the mist are substantially the amount of water that can be contained in the clothes. For this reason, compared with the washing method of heating the entire washing water, the power consumption is small, and the cleaning power can be improved in a short time. In addition, in the conventional warm water washing system, the temperature of the water is gradually increased. In the present embodiment, the warming mist and the warm air are applied to the clothes and the like, and the detergent can be contained in the detergent. The activities of the enzymes have been played since the early days, effectively improving the detergency.

In the case of winter, when the outside temperature or the water temperature is lower, the temperature of the clothes, etc., is extended by the time of the warm-up operation, the fog A, the mist B, the mist E, and the fog F operation. 30 °C heating It is better to 40 °C. In this case, if the supply amount of the mist is excessively increased, the temperature of the clothes or the like may hardly rise. Therefore, for example, the water supply due to the cooling water in the mist E is set to be turned on within 1.5 seconds, and closed within 80 seconds. It is better not to increase the amount of fog supply.
