Fig. 3 is a longitudinal sectional view around the detergent box of the washing machine in the first embodiment. Fig. 4A is a plan view of the water injection device cover of the washing machine in the first embodiment. Fig. 4B is a plan view of the water injection structure of the washing machine in the first embodiment. Fig. 4C is a plan view of the detergent box of the washing machine in the first embodiment.

As shown in FIGS. 3, 4A, and 4B, the water injection device 11 is composed of a water injection device cover 11a on the upper surface, and a water injection structure portion 11b on the lower surface. As a water supply port for introducing water from the water supply valve 80, the water injection device cover 11a is provided with a water supply port 8a for the powder lotion injection part, which is connected to the first water supply valve 81 (refer to FIG. 2); a liquid lotion injection part The water supply port 8b for use; and the water supply port 8c for the softener input portion are connected to the second water supply valve 82 (see FIG. 2). The water introduced from each water supply port flows down toward the water injection structure 11b.

The water injection structure portion 11b is formed in a box shape, and the interior is partitioned into small cells to correspond to the powder lotion input portion 9a, the liquid lotion input portion 9b, or the softener input portion 9c and the silver crystal unit accommodating portion 16. In addition, the small cells corresponding to the softener input portion 9c and the silver crystal cell accommodating portion 16 are common small cells. In addition, in each small compartment, a plurality of nozzles that communicate with the lower side and drop water to the lotion box 9 are formed. In each compartment, corresponding to the powder lotion input portion 9a, the liquid lotion input portion 9b, the softener input portion 9c, and the silver crystal unit accommodating portion 16, there are respectively provided a powder lotion nozzle 13a and a liquid lotion nozzle 13b. Nozzle 14 for softener and nozzle 10 for silver crystal. Thereby, the water injection structure part 11b can independently supply water to the powder lotion input part 9a, the liquid lotion input part 9b, or the softener input part 9c and the silver crystal unit accommodating part 16.

As shown in FIG. 3 and FIG. 4B, the inside of the water supply valve 80 (refer to FIG. 2) and each small compartment are formed as a wide water passage. On the other hand, the lotion nozzle 13, the softener nozzle 14, and the silver crystal nozzle 10 are holes formed with small diameters. With this configuration, when passing through the nozzles, the flow velocity is increased due to the Venturi effect, so the strength of the water falling to the lotion box 9 can be increased.

Moreover, the nozzle 10 for silver crystals is comprised by the 1st nozzle 10a with a large diameter, and the 2nd nozzle 10b with a small diameter. The first nozzle 10a and the second nozzle 10b are arranged on a straight line in the front-rear direction.

As shown in FIG. 4C, a powdery lotion discharge port 30a that opens downward is provided in the center of the powdery lotion input portion 9a, and the lotion water containing the dissolved powdery lotion is discharged downward.

The liquid lotion input portion 9b and the softener input portion 9c are provided with a siphon structure 30b. When the liquid accumulated inside reaches a predetermined liquid level, the siphon structure 30b uses the siphon phenomenon to suck up the liquid and discharge it downward. That is, when a predetermined amount of water is supplied from the nozzle, the liquid lotion or softener that has been dissolved in the water will be conveyed downward by the siphon structure 30b, and spit out to the lotion box accommodating part 12.

The silver crystal unit accommodating portion discharge port 30c is formed at the inner bottom of the silver crystal unit accommodating portion 16, and the water discharged from the silver crystal unit 15 is discharged downward. (Silver crystal unit housing part)

Fig. 5 is a cross-sectional view showing the periphery of the silver crystal unit accommodating portion of the washing machine in the first embodiment. Fig. 6A is a perspective view of the appearance around the accommodating portion of the silver crystal unit showing a state where the silver crystal unit of the washing machine in the first embodiment has been disassembled. Fig. 6B is a perspective view of the appearance around the accommodating portion of the silver crystal unit showing a state where the silver crystal unit of the washing machine in the first embodiment has been installed.

As shown in FIGS. 5, 6A, and 6B, the silver crystal unit accommodating portion 16 is formed in a substantially box shape, and is configured as the silver crystal unit 15 that can be detached.

A plurality of inclined ribs 16c extending up and down are formed in the inner peripheral wall of the silver crystal unit accommodating portion 16. The inclined rib 16c is formed so as to protrude more downward, and when the silver crystal unit 15 is inserted below, it smoothly guides the silver crystal unit 15. The upper and lower end surfaces of the inclined rib 16c abut against the silver crystal unit 15 when the silver crystal unit 15 is completely inserted into the silver crystal unit accommodating portion 16. Thereby, the silver crystal unit 15 is kept in the state of the silver crystal unit accommodating part 16, and even if the lotion box 9 is inverted, it will not fall.

In addition, the silver crystal unit 15 is provided with a hinge portion 22 described later, and the silver crystal unit accommodating portion 16 is provided with a silver crystal unit accommodating portion side hook 16 b. The hinge part 22 not only functions as a hinge structure, but is also configured to be engageable with the silver crystal unit housing part side hook 16b. After the user inserts the silver crystal unit 15 into the silver crystal unit accommodating portion 16, the hinge portion 22 will engage with the side hook 16b of the silver crystal unit accommodating portion. Thereby, the silver crystal unit 15 is in a state of being installed in the silver crystal unit accommodating portion 16.

In addition, the holding of the silver crystal unit 15 by the inclined rib 16c and the installation of the silver crystal unit 15 by the hinge part 22 may be provided with either or both.

In addition, the silver crystal unit 15 has a screw boss portion 23 (described later) protruding on one side surface, and is configured such that the overall shape does not become point-symmetrical. In addition, the silver crystal unit accommodating portion 16 is formed with a cutout 16 a at a position facing the screw boss portion 23 and is configured to not interfere with the screw boss portion 23. By inserting the screw boss portion 23 into the notch 16a, the silver crystal unit 15 is positioned to be a correct position (described later) relative to the silver crystal unit accommodating portion 16, that is, the correct storage position. Therefore, it is possible to prevent the user from installing the silver crystal unit 15 in the wrong direction when installing it. In addition, the structure for positioning provided in the crystal unit 15 does not need to be the screw boss portion 23. (Silver crystal unit)

Fig. 7A is an external perspective view of a state in which the storage box cover of the storage box of the washing machine in the first embodiment is closed. Fig. 7B is an external perspective view of a state in which the storage box cover of the storage box of the washing machine in the first embodiment has been opened.

The silver crystal unit 15 is mainly composed of a silver crystal 29 (described later), a storage box 18 for accommodating the silver crystal 29, and a storage box cover 19.

The silver crystal 29 is formed by mixing a water-soluble diboron trioxide (B2O3) with a silver component having an antibacterial effect, and is formed into a large number of granular small pieces. The silver crystal 29 is formed in a granular shape, so that it has a large surface area and becomes easy to dissolve in water. The silver crystal 29 is dissolved by being immersed in water, and antibacterial silver ions are released into the water. In this way, the silver crystal 29 functions as an auxiliary agent that generates silver ion water and imparts an antibacterial effect to the laundry.

The storage box 18 is formed in a box shape opened at the upper side, and the upper side is covered by the storage box cover 19. The storage box cover 19 is connected to the storage box 18 by a hinge part 22 configured to be bendable.

The storage box cover 19 is provided with a fitting hook convex portion 25 on the outer side of the side surface. On the other hand, on the inner side of the side surface near the opening of the storage box 18, a fitting hook concave portion 26 is provided at a position facing the fitting hook convex portion 25. With these structures, when the storage box cover 19 is closed, the fitting hook convex portion 25 and the fitting hook concave portion 26 engage, and the storage box cover 19 is temporarily fixed to the storage box 18.

The storage box cover 19 is formed with a screw boss portion 23 protrudingly arranged on the side and extending downward. The screw boss portion 23 and the screw seat portion 24 are arranged on opposite sides of the hinge portion 22. In the screw boss portion 23, a screw hole 23a is formed for screwing from below. When the storage box cover 19 is temporarily fixed to the storage box 18, it is screwed in the screw seat portion 24 and the screw boss portion 23 by screws 24a.

In this way, in the state where the storage box cover 19 is closed, the fitting hook convex portion 25 and the fitting hook concave portion 26 will engage and be temporarily fixed. Therefore, the screw 24a is fixed to the screw hole 23a of the screw boss portion 23. During the screwing operation, it is possible to prevent the storage box cover 19 from opening naturally. Therefore, the workability when the silver crystal 29 is enclosed in the storage box 18 is good.

Fig. 8A is a plan view of the storage box of the washing machine in the first embodiment. Fig. 8B is a sectional view of 8B-8B of Fig. 8A. Fig. 8C is a sectional view of 8C-8C of Fig. 8A. Fig. 9A is a plan view of the silver crystal unit of the washing machine in the first embodiment. Fig. 9B is a bottom view of the silver crystal unit of the washing machine in the first embodiment. Fig. 9C is a cross-sectional view of 9C-9C of Fig. 9A.

The storage box cover 19 is provided with a first opening 20 for introducing water into the inside of the silver crystal unit 15, and a second opening 21 for draining water is provided on the bottom surface of the storage box 18, that is, the storage box bottom surface 28. Thereby, the silver crystal unit 15 discharges the silver ion water generated by immersing the introduced water in the silver crystal 29 from the second opening 21 downward.

The second opening 21 is arranged so as not to be vertically below the first opening 20 and is configured to have a larger opening area than the first opening 20. The first opening 20 is arranged on the end side than substantially the center in the storage box cover 19 and partially overlaps the second opening 21.

In addition, the storage box bottom surface 28 of the storage box 18 is formed to be inclined downward. Thereby, the internal silver crystal 29 moves downward due to its own weight, and it becomes easy to accumulate in the lower part of the inclination.

As shown in FIG. 9C, the first opening 20 and the second opening 21 are integrally molded with the water passage member 27 by insert molding so that the water passage member 27 covers the opening portion. The water-passing member 27 is made of a material different from the storage box 18, and is formed in a mesh shape so that the number of holes becomes about 100 meshes. Thereby, the water-passing member 27 allows water to pass through, and does not allow silver crystals 29 of a certain size or more to pass through. In addition, the silver crystal 29 gradually becomes smaller as it dissolves in water, and the particles of the silver crystal 29 that are dissolved enough to pass through the holes of the water-passing member 27 will not be visually confirmed by the user.

With regard to the washing machine and the silver ion elution device configured as described above, the operation and effect will be described below. (Washing operation)

After the user opens the lid 6 to put the laundry into the washing and dehydration tank 3, and operates the operation display unit 31 to set the operation content, the control device 7 starts the washing operation. The user puts a powder lotion or liquid lotion corresponding to the amount of clothes into the lotion box 9.

After the start of the washing process, the control device 7 opens the first water supply valve 81 and introduces water into the water injection device 11 through the water supply port 8a for the powder lotion injection portion and the water supply port 8b for the liquid lotion injection portion, and the water injection device 11 Water is injected into the powder lotion injection portion 9a and the liquid lotion injection portion 9b through the powder lotion nozzle 13a and the liquid lotion nozzle 13b of the lotion nozzle 13. The lotion in the lotion box 9 is dissolved in water and discharged toward the lotion box accommodating portion 12, and then put into the water tank 4 and the washing and dehydrating tank 3 together with water. When a predetermined amount of water is supplied, the control device 7 closes the first water supply valve 81, and stirs the clothes contained in the washing and dehydrating tank 3 through the rotating disk 5 to perform washing and stirring. After the washing process is over, the washing process will begin.

After the cleaning process starts, the initial cleaning action will begin. In addition, the initial cleaning action can also be performed multiple times. In the initial washing operation, the first water supply valve 81 is opened and the empty powder detergent input portion 9a and liquid detergent input portion 9b are filled with water, and water that does not contain softener and silver ions is supplied to the water tank 4 and the washing Dehydration tank 3. Next, the stirring of the clothes by the turntable 5 is started to wash away the components of the lotion adhering to the clothes.

In order for the water injection device 11 to supply water to the softening agent input portion 9c and the silver crystal unit accommodating portion 16, the control device 7 opens the second water supply valve 82 and supplies water to the softening agent nozzle 14 and the silver crystal nozzle 10. The water released downward from the softener nozzle 14 dissolves the softener put into the softener input portion 9c, is conveyed by the siphon structure 30b, and is discharged to the lotion box accommodating portion 12. The water discharged downward from the nozzle 10 for silver crystals passes through the silver crystal unit 15 to become silver ionized water as described later, and is discharged to the lotion box accommodating part 12. The water containing softener and silver ions that has been discharged to the lotion box accommodating portion 12 is put into the water tank 4 and the washing and dehydrating tank 3. Then, the stirring of the clothes by the turntable 5 is started, so that the softener and silver ions are attached to the clothes. With the end of the final cleaning action, the cleaning process is also over.

Since silver ions are cations, they have the property of being easy to adhere to general clothing containing negatively polarized molecular structures. However, when the lotion containing an anionic surfactant is simultaneously injected, the amount of silver ions adhering to the clothes is reduced due to the interaction between the silver ions and the anionic surfactant.

On the other hand, as in this embodiment, when a softener containing a cationic surfactant is added at the same time, it can produce a synergistic effect and firmly adhere to clothes. Therefore, by allowing the water injection device 11 to supply water to the softener input portion 9c and the silver crystal unit accommodating portion 16, the antibacterial effect brought by the silver ions can be efficiently obtained. (Motion around the silver crystal unit)

Fig. 10 is a schematic diagram showing the flow of water flowing into the silver crystal unit in a longitudinal section around the detergent box of the washing machine in the first embodiment. 11 is a schematic diagram showing the flow of water flowing into the silver crystal unit in a cross section around the detergent box of the washing machine in the first embodiment.

When the second water supply valve 82 is opened, water is introduced into the water injection device 11. The water introduced into the water injection device 11 is released downward from the first nozzle 10 a and the second nozzle 10 b of the silver crystal nozzle 10, and is supplied to the silver crystal unit 15 through the water passing member 27.

As shown in FIG. 11, the nozzle 10 for silver crystals is formed as a hole with a small diameter. Generally speaking, the flow width of the water released from the hole gradually widens as it leaves the hole.

The silver crystal unit 15 is configured such that the distance between the water-passing member 27 and the silver crystal nozzle 10 is close (approximately 5 mm). Thereby, the water discharged from the nozzle 10 for silver crystals reaches the water passage member 27 earlier than the width of the water flow is widened. The water flow with a narrow width can be efficiently supplied into the silver crystal unit 15 through the fine mesh of the water passage member 27 without colliding with the water passage member 27 and scattered to the surroundings.

As shown in FIG. 10, the water injected from the first nozzle 10a with a large diameter and the second nozzle 10b with a small diameter collides with the silver crystal 29 in the storage box 18 and becomes a turbulent flow, and the silver crystal 29 is not missed. The ground gets wet and becomes silver ion water. In this way, since the entire silver crystal 29 is uniformly exposed to the water every time the water is poured, the concentration of the silver ion water can be kept constant during each washing operation.

As shown in FIG. 11, the silver crystal 29 moves inside the storage box 18 due to the water flow. Thereby, the silver crystal 29 will be in contact with the water without any omission, and rub against the particles of other silver crystals 29 or the inner wall of the storage box 18 to quickly dissolve in the water. In this way, by filling the storage box 18 with granular silver crystals 29 so that there are gaps between the silver crystals 29, the silver crystals 29 can be immersed in water without any omission.

In addition, the water introduced into the silver crystal unit 15 from the first opening 20 does not fall linearly, but bypasses the inside of the storage box 18 and reaches the second opening 21. In this way, by disposing the second opening 21 so as not to be vertically below the first opening 20, the silver crystal 29 can be brought into contact with water over a distance longer than the vertical dimension of the storage box 18. Due to this action, water can be brought into contact with the entire silver crystal 29 without any omission, and therefore, high-concentration silver ion water can be stably generated during each washing operation.

As shown in FIG. 11, the silver ionized water generated in the silver crystal unit 15 is discharged from the second opening 21. In the present embodiment, by providing the second opening 21 to be larger than the first opening 20, the amount of water supply is suppressed from being larger than the amount of drainage, and the overflow of water from the upper portion of the silver crystal unit 15 is suppressed. (Reduction of silver crystal, replacement of silver crystal unit)

Fig. 12A is a cross-sectional view of the silver crystal unit of the washing machine in the first embodiment in a filled state, that is, the 12A-12A cross-sectional view of Fig. 9A. 12B is a cross-sectional view of 12B-12B of FIG. 9A in a state where a small amount of silver crystals in the silver crystal unit of the washing machine in the first embodiment are left.

Since the silver crystal 29 is water-soluble, it will gradually decrease every time the washing operation is performed. As shown in FIGS. 12A and 12B, since the storage box bottom surface 28 of the storage box 18 is inclined, the remaining small amount of silver crystal 29 becomes easy to accumulate in the lower portion of the inclination. Also, as shown in FIG. 10, since the storage box bottom surface 28 of the storage box 18 is inclined downward in the direction in which the first nozzle 10a with a large amount of water is arranged, the remaining small amount of silver crystals 29 can be efficiently dissolved in the water. .

As the silver ions continue to dissolve, the amount of silver crystals 29 will gradually decrease. When the amount of silver crystals 29 is reduced below a certain level, the antibacterial effect on laundry will also decrease. Therefore, the user can replace the silver crystal unit 15 with a new product at an appropriate point in time, thereby maintaining the antibacterial performance of the washing machine.

Since the amount of decrease of the silver crystal 29 is related to the number of executions of the washing operation, the recommended washing times for replacement of the silver crystal unit 15 can be obtained experimentally. In the washing machine in this embodiment, the control device 7 measures the number of executions of the washing operation, and when the number of executions reaches the replacement recommended number of washings, the LED (not shown) of the operation display unit 31 flashes. Thereby, the user can confirm the remaining amount of the silver crystal 29 without visually viewing the inside of the silver crystal unit 15 and therefore does not need to provide a window configured to visually confirm the inside of the silver crystal unit 15.

In addition, the remaining usable number of times of the silver crystal unit 15 may also be notified in the operation display unit 31. In this way, the user can grasp the replacement time of the silver crystal unit 15 early, and therefore can prepare the silver crystal unit 15 for replacement in advance. (Function, etc.)

As described above, the silver crystal unit 15 in this embodiment is configured to enclose the water-soluble silver crystal 29 and can be installed in a washing machine, and includes: the first opening 20 for introducing water into the silver crystal unit 15; and 2 The opening 21 discharges the water in the silver crystal unit 15, and the first opening 20 and/or the second opening 21 are provided with a water-passing member 27 formed in a mesh shape.

With this configuration, the silver crystal unit 15 is made water-permeable, and even if the silver crystal 29 has a small particle size, it can be prevented from leaking from the second opening 21.

Therefore, small silver crystals 29 that are easy to dissolve in water can be used, so that a certain concentration of silver ion water can be stably generated during each washing operation.

Like this embodiment, the second opening 21 may be provided so as not to face the first opening 20.

With this structure, the water introduced from the first opening 20 does not linearly pass through the silver crystal unit 15, but is discharged from the second opening over a long distance, so that the water can penetrate the silver crystal without any omission. 29 overall.

Therefore, the concentration of silver ions can be kept almost constant during each washing operation, so that the antibacterial effect can be stably obtained.

As in this embodiment, in the direction in which the silver crystal unit 15 is installed in the washing machine, the first opening 20 is provided on the upper surface of the silver crystal unit 15, and the second opening 21 is provided on the lower surface of the silver crystal unit 15, and The second opening 21 is arranged so as to partially overlap with the position where the first opening 20 is projected downward.

With this configuration, even when the areas of the upper and lower surfaces of the silver crystal unit 15 are small, the water introduced from the first opening 20 can be discharged from the second opening over a long distance.

Therefore, even if the area of the upper surface and the lower surface of the silver crystal unit 15 is narrowed, a high antibacterial effect can be obtained, so the silver crystal unit 15 can be miniaturized.

As in this embodiment, the area of the second opening 21 may be larger than the area of the first opening 20.

With this configuration, the amount of water that can be discharged can be set to be larger than the amount of water that can be introduced.

Therefore, the water introduced from the first opening 20 can be reliably drained from the second opening 21.

As in the present embodiment, the silver crystal unit 15 may also include a storage box 18 and a silver crystal 29 enclosed in the storage box 18, and the water-passing member 27 is composed of other parts different from the storage box 18.

With this configuration, since the water-passing member 27 can be a member with a fine mesh, the grain size of the silver crystal 29 can be reduced.

As in the present embodiment, the storage box bottom surface 28 of the silver crystal unit 15 may be provided with a second opening 21 and formed obliquely, and the second opening 21 may be provided at a lower position in the inclination of the storage box bottom surface 28.

With this structure, even when the silver crystal 29 is consumed and becomes a small amount, the silver crystal 29 is still stored in the lower part of the slope due to the inclination of the bottom surface 28 of the storage box and the weight of the auxiliary agent.

As in this embodiment, the washing machine may also include: a silver crystal unit 15; a lotion box 9 provided with a silver crystal unit accommodating portion 16 for detachably accommodating the silver crystal unit 15; and a water injection device 11 that faces the silver crystal unit from above Unit 15 supplies water.

With this configuration, water containing silver ions can be poured into the water tank 4 and the washing and dehydrating tank 3 to allow the silver ions to adhere to the clothes.

Therefore, the antibacterial effect can be obtained efficiently.

As in this embodiment, it is provided with: a silver crystal unit 15 in which the silver crystal 29 is enclosed; a lotion box 9 provided with a silver crystal unit accommodating part 16 for detachably accommodating the silver crystal unit 15; and a water injection device 11 for washing The cartridge 9 supplies water. In addition, the water injection device 11 may also include: a water channel for allowing the water supplied from the second water supply valve 82 to flow; and a silver crystal nozzle 10 for injecting water from the water channel into the silver crystal unit 15 and provided in the opening of the silver crystal nozzle 10 It is formed to be thinner than the width of the waterway.

With this configuration, the water supplied from the second water supply valve 82 can pass through the hole of the silver crystal nozzle 10 to increase the water pressure, and the water supply speed into the silver crystal unit 15 can be increased.

Therefore, the silver crystal 29 can be efficiently dissolved to increase the concentration of silver ions, so even a small amount of the silver crystal 29 can still obtain a high antibacterial effect.

Like this embodiment, the silver crystal 29 may be formed in a granular shape.

With this configuration, by allowing the particles of the silver crystal 29 to slide against each other, the speed at which the silver crystal 29 is eluted into water can be increased.

Like this embodiment, the nozzle 10 for silver crystals may be provided with a plurality of nozzles.
