(Water injection device, detergent box)
Fig. 2 is an exploded perspective view of the periphery of the upper casing of the washing machine of embodiment 1.
As shown in fig. 2, a detergent box housing 12 is formed at the rear upper portion of the upper case 2, and the detergent box housing 12 houses the detergent box 9 so as to be detachable. A water filling device 11 is provided above the detergent box 9, and the water filling device 11 introduces tap water through the water supply valve 80 and fills water into the detergent box 9 stored in the detergent box storage section 12. The water introduced from the water injection device 11 into the detergent box 9 is discharged into the detergent box housing portion 12 through the inside of the detergent box 9, and is introduced into the water tank 4.
The detergent box 9 is formed in a box shape opening upward. A grip portion 9d configured to be gripped by a user is provided on the front side of the detergent box 9. The grip 9d is formed so as to be flush with the laundry inlet 2a formed in the upper case 2 in a state where the detergent box 9 is stored in the detergent box storage section 12.
The inside of the detergent box 9 is formed with: a detergent input unit 9a into which detergent is input; a laundry detergent input unit 9b into which laundry detergent is input; and a softener input unit 9c into which a softener is input. A silver crystal unit storage section 16 to which the silver crystal unit 15 is detachably attached is formed behind the softener input section 9 c. The silver crystal unit 15 and the silver crystal unit housing portion 16 will be described later.
Fig. 3 is a longitudinal sectional view around a detergent box of the washing machine of embodiment 1. Fig. 4A is a plan view of a water injection device cover of the washing machine of embodiment 1. Fig. 4B is a plan view of a water injection structure of the washing machine of embodiment 1. Fig. 4C is a top view of a detergent box of the washing machine of embodiment 1.
As shown in fig. 3, 4A and 4B, the water injection device 11 includes a water injection device cover 11a as an upper surface and a water injection structure portion 11B as a lower surface. The water filling device cover 11a is provided with a water supply port 8a for a detergent input portion connected to a 1 st water supply valve 81 (see fig. 2), a water supply port 8b for a detergent input portion, and a water supply port 8c for a softener input portion connected to a 2 nd water supply valve 82 (see fig. 2) as water supply ports for introducing water to the water supply valve 80. The water introduced from each water supply port flows down toward the water injection structure portion 11b.
The water injection structure 11b is formed in a box shape, and the inside is divided into cells so as to correspond to the detergent input portion 9a, the liquid laundry detergent input portion 9b, the softener input portion 9c, and the silver crystal unit storage portion 16. Among them, the cells corresponding to the softener input section 9c and the silver crystal unit storage section 16 are common cells. In addition, a plurality of nozzles are formed in each of the cells, which communicate with the lower side to drop water into the detergent box 9. In each of the cells, a washing powder nozzle 13a, a washing liquid nozzle 13b, a softener nozzle 14, and a silver crystal nozzle 10 are provided corresponding to the washing powder input unit 9a, the washing liquid input unit 9b, the softener input unit 9c, and the silver crystal unit storage unit 16, respectively. Thus, the water injection structure 11b can supply water to the detergent input unit 9a, the liquid laundry detergent input unit 9b, the softener input unit 9c, and the silver crystal unit storage unit 16 independently.
As shown in fig. 3 and 4B, the inside of the water supply valve 80 (see fig. 2) and each of the cells are formed as a water channel having a wide width. On the other hand, the detergent nozzle 13, the softener nozzle 14, and the silver crystal nozzle 10 are formed as holes having a small diameter. According to this structure, the flow velocity is increased by the venturi effect when passing through each nozzle, and therefore, the momentum of water falling down to the detergent box 9 can be enhanced.
The silver crystal nozzle 10 includes a 1 st nozzle 10a having a larger diameter and a 2 nd nozzle 10b having a smaller diameter. The 1 st nozzle 10a and the 2 nd nozzle 10b are arranged on a straight line in the front-rear direction.
As shown in fig. 4C, a detergent discharge port 30a is provided at the center of the detergent inlet 9a and opens downward, and detergent water containing dissolved detergent is discharged downward.
A siphon structure 30b is provided in the liquid laundry detergent dispenser 9b and the softener dispenser 9 c. The siphon structure 30b sucks up the liquid by a siphon phenomenon when the liquid stored therein reaches a predetermined liquid level, and discharges the liquid downward. That is, when a predetermined amount of water is supplied from the nozzle, the liquid laundry detergent or softener dissolved in the water is transported downward by the siphon structure 30b, and is discharged to the detergent box housing section 12.
A discharge port 30c of the silver crystal unit accommodating portion is formed in the inner bottom of the silver crystal unit accommodating portion 16, and water discharged from the silver crystal unit 15 is discharged downward.
(silver Crystal Unit storage section)
Fig. 5 is a cross-sectional view showing the vicinity of a silver crystal unit housing part of the washing machine according to embodiment 1. Fig. 6A is an external perspective view showing the periphery of the silver crystal unit accommodating section in a state in which the silver crystal unit is removed in the washing machine of embodiment 1. Fig. 6B is an external perspective view showing the periphery of the silver crystal unit accommodating section in the state where the silver crystal unit is mounted in the washing machine of embodiment 1.
As shown in fig. 5, 6A and 6B, the silver crystal unit storage section 16 is formed in a box shape, and is configured to be detachable from the silver crystal unit 15.
A plurality of inclined ribs 16c are formed on the inner peripheral wall of the silver crystal unit accommodating section 16 so as to extend vertically. The inclined rib 16c is formed to protrude downward, and smoothly guides the silver crystal unit 15 when the silver crystal unit 15 is inserted downward. In a state where the silver crystal unit 15 is completely inserted into the silver crystal unit accommodating section 16, the end surfaces in the up-down direction of the inclined rib 16c are in contact with the silver crystal unit 15. Thereby, the silver crystal unit 15 is held by the silver crystal unit accommodating section 16, and does not fall even when the detergent box 9 is inverted.
The silver crystal unit 15 is provided with a hinge portion 22 described later, and the silver crystal unit housing portion 16 is provided with a silver crystal unit housing portion side claw 16b. The hinge 22 not only functions as a hinge structure, but also is configured to be engageable with the silver crystal unit storage unit side claw 16b. When the user inserts the silver crystal unit 15 into the silver crystal unit accommodating section 16, the hinge section 22 engages with the silver crystal unit accommodating section side claw 16b. Thereby, the silver crystal unit 15 is mounted in the silver crystal unit housing portion 16.
The holding of the silver crystal unit 15 by the inclined rib 16c and the mounting of the silver crystal unit 15 by the hinge portion 22 may be either one or both of the above.
The silver crystal unit 15 is configured such that a screw boss portion 23 (described later) protrudes from one side surface, and the entire shape thereof is not point-symmetrical. The silver crystal unit housing portion 16 is provided with a notch 16a at a position facing the screw boss portion 23, and is configured so as not to 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 at a correct storage position, which is a positive position (described later) with respect to the silver crystal unit storage portion 16. Therefore, it is possible to suppress the situation in which the user performs the mounting in the wrong direction when mounting the silver crystal unit 15. The positioning structure provided in the silver crystal unit 15 may be other than the screw boss portion 23.
(silver Crystal Unit)
Fig. 7A is an external perspective view of the storage box of the washing machine of embodiment 1 in a state in which the storage box cover is closed. Fig. 7B is an external perspective view of the storage box of the washing machine of embodiment 1 in a state in which the storage box cover is opened.
The silver crystal unit 15 mainly includes a silver crystal 29 (described later with reference to fig. 3), a storage case 18 storing the silver crystal 29, and a storage case cover 19.
Silver crystals 29 are formed from water-soluble diboron trioxide (B 2 O 3 ) The silver-containing material having an antibacterial effect is formed into a plurality of granular small pieces. The silver crystals 29 are formed into a granular shape to have a large surface area and to be easily dissolved in water. The silver crystals 29 are eluted by being immersed in water, thereby releasing silver ions having antibacterial properties into the water. Thus, the silver crystal 29 functions as an auxiliary agent for generating silver ion water and exerting an antibacterial effect on the laundry.
The storage case 18 is formed in a box shape with an upper opening, and is covered by a storage case cover 19. The storage box cover 19 is connected to the storage box 18 by a hinge portion 22 configured to be bendable.
A fitting claw protrusion 25 is provided on the outer side of the side surface of the storage box cover 19. On the other hand, a fitting claw recess 26 is provided at a position facing the fitting claw protrusion 25 on the inner side of the side surface in the vicinity of the opening of the storage case 18. According to the above configuration, in a state where the storage box cover 19 is closed, the fitting claw convex portion 25 and the fitting claw concave portion 26 are engaged, and the storage box cover 19 is temporarily fixed to the storage box 18.
The storage box cover 19 is disposed so as to protrude laterally, and is formed with a screw boss portion 23 extending downward. The screw boss portion 23 and the screw seat portion 24 are disposed on opposite sides of the hinge portion 22. The screw boss portion 23 is formed with a screw hole 23a for screw fixation from below. The housing box cover 19 is screwed to the screw seat portion 24 and the screw boss portion 23 by the screw 24a in a state of being temporarily fixed to the housing box 18.
In this way, in the state where the housing lid 19 is closed, the fitting claw convex portion 25 and the fitting claw concave portion 26 are engaged and temporarily fixed, so that when the screw member 24a is screwed to the screw hole 23a of the screw boss portion 23, the housing lid 19 can be prevented from being opened naturally. Therefore, the operability when the silver crystal 29 is put into the storage case 18 is good.
Fig. 8A is a plan view of a storage case of the washing machine of embodiment 1. Fig. 8B is a cross-sectional view of 8B-8B of fig. 8A. Fig. 8C is a cross-sectional view of 8C-8C of fig. 8A. Fig. 9A is a plan view of a silver crystal unit of the washing machine of embodiment 1. Fig. 9B is a bottom view of a silver crystal unit of the washing machine of embodiment 1. Fig. 9C is a cross-sectional view of 9C-9C of fig. 9A.
The storage box cover 19 is provided with a 1 st opening 20 for introducing water into the silver crystal unit 15, and the storage box bottom surface 28, which is the bottom surface of the storage box 18, is provided with a 2 nd opening 21 for discharging water. Thereby, the silver crystal unit 15 discharges the silver ion water generated by impregnating the silver crystal 29 with the introduced water downward from the 2 nd opening 21.
The 2 nd opening 21 is disposed so as not to be vertically below the 1 st opening 20, and is configured so that the opening area is larger than the opening area of the 1 st opening 20. The 1 st opening 20 is disposed on the end side of the storage box cover 19 from the substantially center, and partially overlaps the 2 nd opening 21.
The bottom surface 28 of the storage case 18 is formed obliquely downward. As a result, the silver crystal 29 in the interior moves downward by its own weight and tends to remain in the inclined lower portion.
As shown in fig. 9C, the 1 st opening portion 20 and the 2 nd opening portion 21 are integrally molded with the water passing member 27 by insert molding in such a manner that the water passing member 27 covers the opening portions thereof. The water passage member 27 is made of a material different from the storage case 18, and is formed in a mesh shape so that the mesh size is about 100 mesh. Thus, the water-passing member 27 passes water and does not pass silver crystals 29 having a size equal to or larger than a predetermined size. In addition, the silver crystals 29 gradually become smaller as they dissolve in water, and particles of the silver crystals 29 dissolved to the size of the mesh passing through the water passing member 27 are not observed by the user.
The operation and action of the washing machine and the silver ion elution device configured as described above will be described below.
(washing operation)
The user opens the cover 6 to input clothes into the washing/dehydrating tub 3, and operates the operation display unit 31 to set the operation contents, so that the control device 7 starts the washing operation. The user inputs laundry powder or liquid laundry detergent in an amount corresponding to the amount of laundry into the detergent box 9.
When the washing process starts, the control device 7 opens the 1 st water supply valve 81, water is introduced into the water injection device 11 through the water supply port 8a for the detergent injection portion and the water supply port 8b for the liquid laundry detergent injection portion, and the water injection device 11 injects water into the detergent injection portion 9a and the liquid laundry detergent injection portion 9b through the detergent nozzle 13a and the liquid laundry detergent nozzle 13 b. The detergent in the detergent box 9 is dissolved in water and discharged to the detergent box housing portion 12, and is put into the water tank 4 and the washing and dehydrating tank 3 together with the water. After a predetermined amount of water is supplied, the control device 7 closes the 1 st water supply valve 81, agitates the laundry stored in the washing and dehydrating tub 3 by the pulsator 5, and thereby agitates the laundry. When the washing process is completed, the rinsing process is started.
When the rinsing process starts, an initial rinsing action is started. In addition, the initial rinsing action may be performed a plurality of times. In the initial rinsing operation, the 1 st water supply valve 81 is opened, water is injected into the empty detergent injection portion 9a and the detergent injection portion 9b, and water containing no softener and silver ions is supplied to the water tank 4 and the washing and dehydrating tank 3. Next, agitation of the laundry by the pulsator 5 is started, and the detergent adhering to the laundry is rinsed off.
In order to supply water from the water injection device 11 to the softener input section 9c and the silver crystal unit storage section 16, the control device 7 opens the 2 nd water supply valve 82 to supply water to the softener nozzle 14 and the silver crystal nozzle 10. The water released downward from the softener nozzle 14 dissolves the softener introduced into the softener introduction portion 9c, and is transported by the siphon structure 30b to be discharged to the detergent box storage portion 12. The water discharged downward from the silver crystal nozzle 10 passes through the silver crystal unit 15 as described later to become silver ion water, and is discharged to the detergent box housing portion 12. The water containing the softener and silver ions discharged to the detergent box housing portion 12 is put into the water tank 4 and the washing and dehydrating tank 3. Next, stirring of the laundry by the pulsator 5 is started, and the softener and silver ions are attached to the laundry. The final rinsing action is ended and the rinsing process is completed.
Since silver ions are cations, they have a property of being easily attached to general clothing including a negatively polarized molecular structure. However, in the case where silver ions are simultaneously added to a detergent containing an anionic surfactant, interaction occurs between the silver ions and the anionic surfactant, and thus the amount of silver ions attached to laundry is reduced.
On the other hand, as in the present embodiment, when silver ions are simultaneously added to the softener containing a cationic surfactant, a synergistic effect can be exhibited, and the softener can be firmly attached to clothing. Therefore, by supplying water from the water injection device 11 to the softener input section 9c and the silver crystal unit storage section 16, the antibacterial action of silver ions can be obtained efficiently.
(action around silver Crystal Unit)
Fig. 10 is a schematic view showing water flows flowing into silver crystal units in a vertical section around a detergent box of the washing machine according to embodiment 1. Fig. 11 is a schematic view showing water flows flowing into silver crystal units at a cross section around a detergent box of the washing machine of embodiment 1.
When the 2 nd 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 discharged downward from the 1 st nozzle 10a and the 2 nd nozzle 10b as the silver crystal nozzle 10, and is supplied to the silver crystal unit 15 through the water passage member 27.
As shown in fig. 11, the silver crystal nozzle 10 is formed as a hole having a small diameter. Typically, the water released from the holes will gradually widen in width as it moves away from the holes.
The silver crystal unit 15 is configured such that the water passage member 27 is positioned closer to the silver crystal nozzle 10. Thus, the water discharged from the silver crystal nozzle 10 reaches the water passage member 27 before the width of the water flow becomes wider. The water flow having a narrow width can pass through the thin mesh of the water passage member 27, and thus can be efficiently supplied into the silver crystal unit 15 while maintaining the potential.
As shown in fig. 10, the water injected from the 1 st nozzle 10a having a larger diameter and the 2 nd nozzle 10b having a smaller diameter generates turbulence in the storage case 18. The water that becomes turbulent causes the silver crystals 29 to be immersed in the water without any loss, and thus becomes silver ion water with a high concentration. Further, since the entire silver crystal 29 is uniformly soaked in water at each water injection, the concentration of silver ion water can be kept constant at each washing operation.
As shown in fig. 11, the granular silver crystals 29 move inside the storage case 18 by a water flow. Thus, the silver crystals 29 are surely brought into contact with water, and rubbed against the particles of other silver crystals 29 or the inner wall of the storage case 18, thereby being rapidly dissolved in water. In this way, the storage case 18 is filled with the granular silver crystals 29 with gaps between the silver crystals 29, and the silver crystals 29 can be quickly dissolved in water.
The water introduced from the 1 st opening 20 into the silver crystal unit 15 does not go down straight but goes around the inside of the storage case 18 to reach the 2 nd opening 21. By disposing the 2 nd opening 21 so as not to be located vertically below the 1 st opening 20 in this way, the silver crystal 29 and water can be brought into contact over a range of distances longer than the longitudinal dimension of the storage case 18. According to this action, water can be brought into contact with the entire silver crystal 29 without fail, and therefore, silver ion water with a high concentration can be stably produced at each washing operation.
As shown in fig. 11, silver ion water generated in the silver crystal unit 15 is discharged from the 2 nd opening 21. In the present embodiment, the 2 nd opening 21 is provided larger than the 1 st opening 20, whereby the water supply amount exceeding the water discharge amount is suppressed and the water overflowing 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 sectional view of fig. 9A-12A with silver crystals of a silver crystal unit of the washing machine of embodiment 1 in an emphasized state. Fig. 12B is a sectional view of fig. 9A through 12B in which silver crystals of the silver crystal unit of the washing machine of embodiment 1 remain in a small amount.
Since the silver crystals 29 are water-soluble, they gradually decrease each time the washing operation is performed. As shown in fig. 12A and 12B, since the bottom surface 28 of the storage case 18 is inclined, a small amount of silver crystals 29 remain easily in the inclined lower portion. Further, as shown in fig. 10, the bottom surface 28 of the storage case 18 is inclined downward in the upward direction in which the 1 st nozzle 10a having a large water discharge amount is disposed, so that a small amount of the silver crystal 29 remaining can be efficiently dissolved in water.
As the dissolution of silver ions proceeds, the amount of silver crystals 29 gradually decreases, and when the amount of silver crystals 29 decreases to a certain level or less, the antibacterial effect on laundry is also reduced. Accordingly, the user can maintain the antibacterial performance of the washing machine by replacing the silver crystal unit 15 with a new one at an appropriate timing.
The amount of decrease in the silver crystal 29 is correlated with the number of times of execution of the washing operation, and therefore the recommended number of times of replacement of the silver crystal unit 15 is found experimentally. In the washing machine of the present embodiment, the control device 7 measures the number of times of execution of the washing operation, and when the number of times of execution reaches the replacement recommended number of times of washing, the LED (not shown) of the operation display unit 31 is made to blink. Accordingly, the user can confirm the remaining amount of the silver crystals 29 without observing the inside of the silver crystal unit 15, and thus, there is no need to provide a window configured to be able to visually recognize the inside of the silver crystal unit 15.
In addition, the remaining number of times of use of the silver crystal unit 15 may be notified in the operation display unit. Accordingly, the user can grasp the replacement timing of the silver crystal unit 15 early, and thus can prepare the silver crystal unit 15 for replacement in advance.

As in the present embodiment, the silver crystal unit storage section 16 may be formed with inclined ribs 16c for guiding the silver crystal unit 15 in the insertion direction.
According to this structure, the inclined rib 16c guides the silver crystal unit 15 in the insertion direction, and thus can be inserted smoothly. In addition, since the contact area between the silver crystal unit 15 and the silver crystal unit accommodating section 16 is small, friction at the time of insertion can be reduced.
As in the present embodiment, a hinge portion 22 may be provided at an upper portion of the silver crystal unit 15, and the hinge portion 22 may be locked to the silver crystal unit accommodating portion side claw 16b by inserting the silver crystal unit 15 into the silver crystal unit accommodating portion 16.
