A portion of the heating unit 18 provided in the circulation path 16 has a heat dissipation unit 18A. When the heating unit 18 operates, the heat dissipation portion 18A becomes high temperature, so the air flowing in the circulation path 16 is heated while passing around the heat dissipation portion 18A to become hot air.

The treatment water unit 9 includes: a box body (tank) 21, which is arranged at a position Z1 above the water tank 3 in the tank body 2; an inflow path 22 branches from an upstream part of the water supply path 4 that is closer to one end 4A than the water supply valve 13 And connected with the box body 21; and the inflow valve 23, which is arranged in the inflow path 22, can be opened/closed. The treated water unit 9 includes: a supply path 24 extending from the box body 21 to the bottom Z2, and its lower end is disposed in the water cylinder 3; a supply part 25 is located at the lower end of the supply path 24; an outflow path 26 is from the box body 21 to The bottom Z2 is extended and connected to the water cylinder 3; and the outflow valve 27 is located in the outflow path 26 and can be opened/closed.

Referring to Fig. 2, which is a schematic longitudinal sectional front view of the treated water unit 9, the box body 21 includes: a bottom wall 21A; an annular side wall 21B standing up from the entire area of the outer edge of the bottom wall 21A; and a top wall 21D, The inner space 21C of the case 21 surrounded by the bottom wall 21A and the side wall 21B is closed from the upper side Z1. The upper surface of the bottom wall 21A and the inner peripheral surface of the side wall 21B constitute the inner surface portion of the case 21 .

The top wall 21D is provided with a loading port 21E penetrating the top wall 21D in the up-down direction Z, and a lid 21F for opening/closing the loading port 21E. A rib-shaped pressing member 21G protruding downward Z2 is provided on the lower surface of the cover 21F. An opening 2E for inserting a cover 21F is provided in a top wall 2D of the case 2 (see FIG. 1 ).

The inflow path 22 communicates with the internal space 21C of the case body 21 by, for example, being bent upward Z1 on the way and connected to the side wall 21B or the top wall 21D of the case body 21 . When the inflow valve 23 is opened, the tap water from the faucet flows into the internal space 21C of the case 21 through the water supply path 4 and the inflow path 22 . Therefore, the inflow valve 23 functions as a water supply unit that supplies water into the case 21 . When the inflow valve 23 is closed, the water supply to the box body 21 will stop.

The upper end portion of the supply path 24 is connected to the bottom wall 21A of the box body 21, and the lower end portion of the supply path 24 passes through the second portion 3F of the front wall 3C of the water cylinder 3 and is bent toward the rear Y2, and faces the drum from the entrance and exit 6G of the drum 6. 6 (refer to Figure 1). An example of the supply unit 25 is an ultrasonic vibrator, and is attached to the lower end of the supply path 24 . The function of the supply unit 25 will be described later.

The outflow path 26 extends downward Z2 from the bottom wall 21A of the case 21 and is connected to the second portion 3F of the front wall 3C of the water tank 3 (see FIG. 1 ). When the inflow valve 23 is opened while the outflow valve 27 is closed, water is accumulated in the internal space 21C of the case 21 . At this time, part of the water in the case body 21 also exists in the upstream region of the outflow path 26 above the upper Z1 than the outflow valve 27 . Therefore, this upstream region can also be regarded as a part of the internal space 21C of the case 21 . When the outflow valve 27 is opened, the water in the box body 21 flows out into the water cylinder 3 through the outflow path 26, and then is discharged out of the machine from the drain path 5 (refer to FIG. 1 ). Therefore, the outflow valve 27 functions as a drain that drains the water in the case 21 .

The treated water unit 9 further includes a mesh member 28 , a water level sensor 29 , a vibrator 30 , and a heater 31 arranged in the case 21 .

The net member 28 is made of nonwoven fabric in a bag shape and has water absorption. As a material of the net member 28, 100% polyester fiber can be used. In addition, as an example of a suitable product of the net member 28, "water-absorbent sheet (Japanese: jamgard)" produced by Toyobo Co., Ltd., which is easy to obtain and excellent in durability, chemical resistance, antibacterial property, and processability, can be used. Water-soluble beads B for treating laundry L in drum 6 are housed in net member 28 . In this embodiment, the beads B are glass beads mixed with silver, but may be titanium oxide beads or hypochlorous acid beads used for photocatalysts. The mesh of the mesh member 28 is set to such a size that water in the case 21 can flow back and forth without passing the dew beads B that become smaller due to use or the like.

The user accesses the cover 21F of the box body 21 from the opening 2E of the top wall 2D of the box body 2 to open the filling port 21E, and fills the net member 28 wrapped with many condensation beads B into the inner space of the box body 21 from the filling port 21E 21C. Then, when the user closes the filling port 21E with the cover 21F, as shown in FIGS. The net member 28 wrapped with the bead B may be configured as a detachable box with respect to the box body 21 .

The net member 28 is pressed to the upper surface of the bottom wall 21A of the case body 21 from above Z1 by the pressing member 21G of the cover 21F within the case body 21 . If water is stored in the case 21 in this state, treated water in which silver ions, which are components of the bead B, are dissolved is generated in the case 21 . The treated water has cleaning effects such as a sterilization effect, an antibacterial effect, and a deodorizing effect, and particularly has an antibacterial effect. In addition, as another cleansing effect, an aroma effect can also be mentioned, and the pod B in this case can be comprised with an aroma agent.

The water level sensor 29 is a sensor for detecting the water level in the case 21 . As the water level sensor 29, a float switch can be used. The vibrator 30 is arranged in the case body 21 at a position immersed in water, and vibrates the water in the case body 21 . The heater 31 is arranged in the case body 21 at a position immersed in water, and heats the water in the case body 21 . By vibrating or heating the water in the case 21, the silver ion concentration of the treated water in the case 21 can be rapidly increased, so that high-concentration treated water can be produced in a short time.

FIG. 3 is a block diagram showing the electrical configuration of the washing machine 1 . Washing machine 1 further includes control unit 32 . The control unit 32 is configured, for example, to include memories such as CPU (Central Processing Unit: Central Processing Unit), ROM (Read Only Memory: Read Only Memory) or RAM (Random Access Memory: Random Access Memory), and a timer for timing. Microcomputer, and built in the casing 2 (referring to Fig. 1). The motor 7, the water supply valve 13, the drain valve 14, the air blower 17, the heating unit 18, the inflow valve 23, the supply unit 25, the outflow valve 27, the water level sensor 29, the vibrator 30 and the heater 31 are respectively electrically connected to the control unit 32 .

The controller 32 controls the motor 7 to rotate the drum 6 at a desired rotation speed. The control unit 32 controls opening/closing of the water supply valve 13 , the drain valve 14 , the inflow valve 23 , and the outflow valve 27 . The control unit 32 controls the respective operations of the air blower 17 , the heating unit 18 , the supply unit 25 , the vibrator 30 , and the heater 31 . The detection result of the water level sensor 29 is input to the control part 32 in real time.

The control unit 32 performs a washing operation. The washing operation includes an initial preparation process, a washing process after the preparation process, a rinsing process performed one or more times after the washing process, and a dehydration process performed after the final rinsing process. The washing operation may also be a washing and drying operation further including a drying process performed after the dehydration process.

During preparation, control unit 32 operates motor 7 to rotate drum 6 at, for example, 100 rpm, and detects the load of laundry L in drum 6 based on the current resistance value of motor 7 at this time. The load corresponds to the storage capacity of laundry L in drum 6 . An example of the storage capacity of the laundry L is the weight of the laundry L. As shown in FIG.

Based on the detected load, the control unit 32 determines the respective required amounts of the detergent and the softener, and the target water levels in the water tub 3 during the washing process and the rinsing process. The required amounts of detergent and softener for each load and the target water level for each load are set in advance and stored in the memory of the control unit 32 .

In the cleaning process, the control unit 32 first performs water supply processing by opening the water supply valve 13 in a state in which the drain valve 14 is closed. As a result, the water from the water supply channel 4 flows into the water tank 3 and is stored, so that the water level in the water tank 3 rises. When the water level in the water tank 3 rises to the target water level, the control unit 32 closes the water supply valve 13 to end the water supply process.

During water supply treatment, a required amount of detergent is dropped into the water tub 3 . It should be noted that the detergent can be manually injected by the user, or can be automatically injected by an automatic input device (not shown) provided in the washing machine 1 . In either case, detergent water generated by dissolving detergent in tap water is stored in water tub 3 .

As the washing process after the water supply process, the control unit 32 rotates the drum 6 in the normal direction or in the reverse direction through the motor 7 . Thereby, the laundry L in the drum 6 is hammer-washed. In beat washing, tumbling is repeated in which laundry L is lifted up to a certain extent, and then naturally falls to the water surface as the rotation direction of drum 6 is switched or the like. Stains are removed from the laundry L by the impact of the tumbling and the detergent components contained in the detergent water stored in the drum 6 . After a predetermined time elapses from the start of the tumbling, the control unit 32 opens the drain valve 14 to drain the water.

At the end of the cleaning process, the control unit 32 performs dehydration processing. In the dehydration process, the control unit 32 dehydrates and rotates the drum 6 with the drain valve 14 opened. The laundry L in the drum 6 is dehydrated by the centrifugal force generated by the dehydration rotation of the drum 6 . The water seeped out of the laundry L by dehydration is drained out of the machine through the drainage channel 5 .

Next, the control unit 32 executes the rinsing process. During rinsing, the controller 32 opens the water supply valve 13 at least for a predetermined time with the drain valve 14 closed to store tap water in the water tub 3 up to the target water level, and then rotates the drum 6 by the motor 7 . Then, since the above-mentioned tumbling is repeated, the laundry L is rinsed with the tap water in the drum 6 . It should be noted that, it may also be that, before tumbling, a required amount of softener is dropped into the water cylinder 3 through an automatic feeding device. After a predetermined time has elapsed from the start of tumbling, the water is drained and the above-mentioned dehydration process is performed, and the rinsing process is completed.

Next, as the dehydration process, the control unit 32 spins the drum 6 for dehydration with the drain valve 14 opened. That is, the dehydration process is substantially the same as the dehydration process in the final stage of the washing process and the dehydration process in the final stage of the rinsing process. The dehydration treatment may also be referred to as an intermediate dehydration process, and the dehydration process may be referred to as a final dehydration process. In the final dehydration process and the intermediate dehydration process, the rotation speed and rotation time of the drum 6 can be different.

During the drying process, the control unit 32 controls the blower unit 17 and the heating unit 18 to generate hot air and circulate the hot air between the drum 6 and the circulation path 16 to supply the laundry L in the drum 6 . Thereby, the laundry L is dried.

The control unit 32 may perform a washing operation of washing the laundry L in a dry state with the treated water in the case 21 . The washing operation may be performed after the drying operation as part of the washing and drying operation, or may be performed independently of the washing operation and the washing and drying operation. The user can select whether to perform the washing operation as part of the washing and drying operation or as a separate operation by operating a display operation unit (not shown) composed of a liquid crystal operation panel or the like provided on the front surface 2A of the cabinet 2 . run to execute. The laundry L to be subjected to the washing operation is not limited to laundry that can be washed in the washing machine 1 , and may be an outerwear, a doll, etc. that cannot be washed in the washing machine 1 . As an example, when the user wants to remove dirt and the like attached to the coat that has been taken off after the user returns home, the washing operation is performed as a separate operation.

Fig. 4 is a flowchart showing a washing operation. When the washing operation is started with the laundry L in a dry state accommodated in the drum 6, the control unit 32 calculates the generation time and the time required for the treatment water to be generated in the case 21, which are the time required to generate the treatment water of a desired concentration. The required amount of water (step S1).

The generation time and the amount of water may vary according to the load of the laundry L in the drum 6. In this case, the control unit 32 executes the above-mentioned preparatory process to detect the load, and calculates the values corresponding to the detected load. Build time and water volume. Equations for calculating the production time and the water volume from the load are preset and stored in the memory of the control unit 32 . It should be noted that the user can also choose whether to perform sterilization or antibacterial on the laundry L by operating the display operation part. In the case of sterilization, a higher concentration of treated water is required than in the case of antibacterial, so The control part 32 calculates the generation time corresponding to each of sterilization and antibacterial.

The control part 32 which calculated the generation time and water quantity starts air washing (step S2). Specifically, the control unit 32 circulates air by operating the air blower 17 while rotating the drum 6 at, for example, 45 rpm. In this way, the laundry L repeatedly dropped due to tumbling in the drum 6 is exposed to the circulating air, whereby dust and the like are removed from the laundry L. As shown in FIG. Such a treatment is called air washing. In addition, the control unit 32 starts the time measurement related to the generation time at the same time as the air washing is started.

The control part 32 which started air washing confirms whether the required amount of water exists in the case 21 by referring to the detection result of the water level sensor 29 (step S3). If the required amount of water has not been reached in the case 21 (NO in step S3), the control unit 32 supplies water to the case 21 by opening the inflow valve 23 with the outflow valve 27 closed (step S4). It should be noted that it can also be determined that the required amount of water exists in the box body 21 when the box body 21 is full of water.

When the required amount of water already exists in the case 21 ("Yes (YES)" in step S3), or when the required amount of water has been stored in the case 21 by water supply (step S4), The control unit 32 checks whether the generation time has elapsed, that is, checks whether the bead B is sufficiently dissolved in water in the case 21 to generate treated water with a concentration higher than required in the case 21 (step S5).

When the generation time has elapsed, that is to say, when the treated water with a concentration higher than the required concentration has been generated in the cartridge 21 (YES in step S5), the control unit 32 confirms that the water from the latest time to the cartridge 21 is Whether or not a predetermined set time has elapsed since water supply, that is, whether or not the concentration of the treated water in the cartridge 21 is too high is checked (step S6). Time information on the last time water was supplied to the cartridge body 21 is temporarily stored in the memory of the control unit 32 . When the treated water in the box body 21 is left for about a set time, the concentration of the treated water may be too high.

When the set time has elapsed, that is to say, when the concentration of the treated water in the box body 21 is too high (YES in step S6), the control unit 32 opens the outflow valve 27 to perform forced drainage until the water is drained. until the box body 21 is empty (step S7). Thereafter, the control unit 32 once resets the time measurement of the generation time, restarts the time measurement of the generation time, repeats the processing from step S3, and opens the inflow valve 23, thereby generating a concentration greater than or equal to the required concentration in the cartridge 21. The treated water (steps S4 and S5).

In this way, the control unit 32 adjusts the concentration of the treated water in the cartridge 21 by opening/closing the inflow valve 23 and the outflow valve 27 respectively. Thus, by preventing excessive dissolution of the beads B, the use time of the beads B can be extended. In particular, if the concentration of the treated water in the box body 21 is adjusted on the basis of adjusting the capacity of the beads B in the box body 21, the use time of the beads B can be adjusted arbitrarily. In addition, the use time of the beads B is several years.

If the set time has not passed, that is to say, when the concentration of the treated water in the cartridge 21 is appropriate ("No (NO)" in step S6), the control unit 32 confirms whether the current time has passed. It becomes the supply start timing of treated water (step S8). The supply start timing is a timing in the middle of the operation time of the washing operation, and is set in advance and stored in the memory of the control unit 32 .

If the current time is the start timing of the supply of treated water (YES in step S8), the control unit 32 starts supplying the treated water by operating the supply unit 25 provided at the lower end of the outflow path 26 connected to the case 21. Supply of the treated water in the drum 6 (step S9). In this manner, the time before the supply start timing during the washing operation is effectively utilized, and after the treated water of required concentration and water volume is prepared in the cartridge 21 in advance, the supply of the treated water is started at the supply start timing.

The supply unit 25 in operation supplies the treated water in the outflow path 26 , that is, the case 21 , into the drum 6 in a mist form by ultrasonic vibration. Thus, the laundry L that has been directly sprayed with the treatment water mist in the drum 6 is not only cleaned by the treatment water for sterilization, antibacterial or deodorization, but also coated with the treatment water to remove dirt, Bacteria will not attach. In addition, the air washing is still going on, so by processing the water mist to circulate between the water tub 3 and the circulation path 16, not only the laundry L can be washed, but also the water tub 3, the drum 6 in the water tub 3, and the circulation path 16 can be cleaned. It should be noted that the supply unit 25 may be a shower valve capable of supplying the treated water in a shower.

In addition, if two minutes have elapsed since the supply of treated water, for example, the control unit 32 will increase the rotation speed of the drum 6 from the previous 45 rpm to a predetermined rotation speed of, for example, 100 rpm or more, and the motor 7 will make the drum 6 rotate at a predetermined speed. Continuous rotation in the same direction. Thus, unlike tumbling, laundry L in drum 6 continues to rotate in the same direction while being attached to inner peripheral surface 6E (see FIG. 1 ) of drum 6 and flattened, without falling. In this state, the control unit 32 supplies the treated water in the case 21 into the drum 6 through the supply unit 25 .

When the set time of, for example, three minutes has elapsed since the supply of the treated water started (YES in step S10), the control unit 32 stops the supply unit 25 to end the supply of the treated water into the drum 6 (step S11). ). At this time, control unit 32 also stops the rotation of drum 6 and stops air blower 17 to end the air washing. Thus, the cleaning operation ends. The control unit 32 can adjust the treatment effect of the treated water by adjusting the set time according to the setting or the like by the user. For example, the longer the set time, the higher the treatment effect such as antibacterial effect.

As described above, in the washing machine 1 , when water is supplied into the case 21 containing the beads B, the beads B are dissolved in water to generate treated water and stored in the case 21 . According to this configuration, by aging the treated water in the case 21 , the concentration of silver ions that is a component of the beads B in the treated water can be increased. Thus, if the high-concentration treated water in the case 21 is supplied into the drum 6 through the supply part 25, the laundry L in the drum 6 can be efficiently treated with the high-concentrated treated water. Therefore, the treatment effect achieved by the treated water can be enhanced.

In addition, the treated water in the case 21 is supplied into the drum 6 in a mist form by the supply part 25, and the treated water can be poured over the laundry L in the drum 6, so the laundry L can be treated more effectively. Therefore, the treatment effect by the treated water can be further enhanced.

In addition, by rotating the drum 6 so that the laundry L in the drum 6 is attached to the inner peripheral surface 6E of the drum 6, by supplying the treated water in the case 21 into the drum 6, the water in the drum 6 can be supplied. The laundry L is poured with treated water all over the ground. Thereby, laundry L can be processed more efficiently. Therefore, the treatment effect by the treated water can be further enhanced.

In addition, by controlling the inflow valve 23 for supplying water into the box body 21 and the outflow valve 27 for discharging water in the box body 21 to adjust the concentration of the treated water in the box body 21, the treated water of an appropriate concentration can be poured into the Therefore, the laundry L in the drum 6 can be treated more effectively. Therefore, the treatment effect by the treated water can be further enhanced.

And, the beads B in the box body 21 are in the state wrapped by the net member 28, so even if the beads B become smaller and become fragments due to dissolution in water or deterioration, they will not flow out of the box body 21. Therefore, it is possible to prevent the beads B from adhering to the laundry L in the drum 6 . In addition, since the water-absorbent net member 28 is in a wet state, the beads B inside are actively wetted to effectively dissolve the beads B in the water in the case body 21 to generate high-concentration treated water.

In addition, by wrapping the bead B with the net member 28, the concentration of the treated water inside the net member 28 is rapidly increased, so by mixing the treated water with the water outside the net member 28 in the box body 21, the water in the box body can be 21 The whole quickly generates high-concentration treated water. That is, compared with the case where the net member 28 is not present, the man-hours for generating high-concentration treated water can be shortened. Moreover, according to the net member 28 which consists of nonwoven fabrics, the bead B which became fragments can be kept inside and cannot flow out of the case 21. FIG. Moreover, you may use the nonwoven fabric which has hydrophilicity for the mesh member 28, and in this case, the dissolution rate of the silver ion in the bead B can be improved.

In addition, the bead B inside the net member 28 is positioned by pressing the net member 28 to the inner surface of the case body 21 by the pressing member 21G (refer to FIG. 2 ), so it is possible to further prevent the bead B from going out of the case body 21. flow out. Therefore, it is possible to further prevent the beads B from adhering to the laundry L in the drum 6 .
