As a result, the case lid 553 can be positioned downward with respect to the case body 551. The ribs 551f may or may not be continuous in the circumferential direction.

A rib 551f is formed at the lower end of the front wall 551a, and a portion below the rib 551f is a bottom wall 551e. On the bottom surface of the bottom wall 551e, the rear end portion 551 g is flat (horizontal plane), and the front end portion to the rear end portion 551 g is an inclined curved surface that descends backward. The bottom wall 551e has a constant thickness and the inner surface and the outer surface have the same shape, but the thickness is not constant and the inner surface and the outer surface may have different shapes.
Since the bottom surface of the bottom wall 551e has an inclined curved surface that descends backward, the silver-containing member 53 easily gathers at the rear portion of the case body 551, and the density of the plurality of silver-containing members 53 in the cartridge case 55 is enhanced. As a result, water remains in the gaps between the dense silver-containing members 53, and the plurality of silver-containing members 53 are maintained in a wet state. The water remaining between the plurality of silver-containing members 53 is in contact with the surface of the silver-containing members 53 for a relatively long time until the water is poured in the next washing operation. As the water continues to come into contact with the surface of the silver-containing member 53, a large amount of silver ions are eluted in the water, and high-concentration silver-ion water is generated in the gaps between the dense silver-containing members 53, and in the next washing operation. When water is poured, a large amount of silver ions flow out and the concentration of silver ions in the water supplied to the washing tub 11 is improved, as compared with simply flowing water through the water channel where the silver-containing member 53 is located. Can be made to.

The rear wall 551d has one or more discharge ports 551h below the rib 551f. A mesh-shaped filter member (not shown) may be provided at the discharge port 551h. As a result, it is possible to prevent the function-imparting member 53 from flowing out together with water. The distance between the portion of the right wall 551c below the rib 551f and the portion of the left wall 551b below the rib 551f becomes smaller as it moves downward. As a result, the width (dimension in the left-right direction) of the powder detergent accommodating portion 311 of the case 31 can be reduced. In addition, the density of the plurality of silver-containing members 53 in the cartridge case 55 can be increased. By increasing the density of the plurality of silver-containing members 53, water can be easily retained (maintained in a wet state) between the silver-containing members 53, and the concentration of silver ions in the water supplied to the washing tub 11 can be increased. Can be secured.

The case body 551 has a rib 551j for stabilizing the cartridge 51 when it is placed on a flat surface instead of the case 31 of the detergent charging section 3. The ribs 551j are formed by extending the inclined surface of the bottom wall 551e in the front-rear direction and having a plurality of ribs (2) at intervals in the left-right direction, and the lower surface thereof is flat. That is, the rib 551j and the rear end portion 551g of the bottom wall 551e are flush with each other.

(3-2-2) Case Lid The case lid 553 is attached to the upper side of the case body 551 so as to cover the upper opening of the case body 551. The case lid 553 has a box shape. The case lid 553 has a square shape or a shape close to a square shape when viewed from above. The case lid 553 has four side walls of a front wall 553a, a left wall 553b, a right wall 553c, and a rear wall 553d, and a top wall 553e, and the lower surface is open.
The top wall 553e has one or more water injection ports 553f for injecting water from the water injection channel into the inside. In other words, the top wall 553e has a plurality of water injection ports 553f in a grid pattern. Further, here, a mesh-shaped filter member (not shown) covering a plurality of water injection ports 553f is provided. As a result, it is possible to prevent the user from accidentally touching the function-imparting member 53 and prevent foreign matter from entering the cartridge 51. Even if the cartridge 51 is turned upside down at the time of replacement, it is possible to prevent the function-imparting member 53 from popping out.

The case lid 553 has an eaves wall 553 g that projects from the front end of the top wall 553e. In the fully open state in which the case 31 in which the cartridge 51 is installed is pulled out to the maximum position, as shown in FIG. 8, only 553 g of the eaves wall projects (exposed) from the upstream water injection channel 162. That is, the eaves wall 553g constitutes the visible portion, and the top wall 553e constitutes the non-visible portion. As a result, for example, the water injection port 553f of the top wall 553e is hidden even in the fully open state of the case 31, and it is possible to prevent the detergent and the softener from being mixed into the cartridge 51 when the detergent and the softener are put into the case 31. It is possible to prevent the detergent and the softener from solidifying inside and making it difficult for water to flow, and to prevent the softener from coming into contact with silver and discoloring the softener.
Further, for example, the type of the function-imparting member 53 housed in the cartridge 51 may be displayed on the upper surface of the eaves wall 553 g. As a result, the type of the function-imparting member 53 housed in the cartridge 51 can be grasped at a glance through the visual recognition unit (eaves wall 553 g), which is user-friendly.
The eaves wall 553 g is inclined downward toward the front side. As a result, the detergent or the like adhering to the eaves wall 553 g can easily fall off, and the eaves wall 553 g can be easily maintained hygienically. Further, since the cartridge 51 is installed in the powder detergent storage unit 311, the detergent or the like that has fallen from the eaves wall 553 g flows into the washing tub 11 by the water injected into the powder detergent storage unit 311.

(3-2-3) Bonding The case body 551 and the case lid 553 have one or a plurality of types of connecting portions.
Here, screwing means and engaging means using screws (not shown) are used.
The screwing means has a through hole through which the screw is inserted and a screw hole through which the screw is screwed. Here, a through hole 551k is formed in an overhanging portion 551m that projects forward from the rib 551f of the front wall 551a of the case body 551, and a screw hole 553h is formed between the eaves wall 553g of the case lid 553 and the front wall 553a. It is formed on the boss portion 553j. As a result, the screws and the like are hidden behind the eaves wall 553 g, so that the design can be enhanced.
In the engaging means, when the case body 551 is covered with the case lid 553, the engaging protrusion engages with the engaging recess. The engaging protrusion 551n is a side wall of the case body 551 and is formed on the upper side of the rib 551f, and the engaging recess 553k is formed on the side wall of the case lid 553.

(3-2-4) Mounting The cartridge 51 has a mounting portion for being detachably mounted on the case 31. The mounting portion is composed of an engaging portion 535 that engages with the case 31. The engaging portion 535 engages with the connecting portion 317 at the rear end of the case 31 from above. Here, the engaging portion 535 has an "L" shape that extends backward from the rear wall 553d of the case lid 553 and then extends downward.
The cartridge 51 is installed in the powder detergent accommodating portion 311 of the case 31 by using the connecting portion 317. Since the powder detergent accommodating portion 311 and the softener accommodating portion 313 are independent, the water injection containing the metal ions does not come into contact with the softener, and even when the function-imparting member 53 elutes the metal ions, the metal ions are present. It is possible to prevent darkening of the laundry due to contact with the softener.

(3-2-5) Positioning The cartridge 51 and the case 31 have a positioning portion for being mounted on the case 31 in a positioned state. Positioning here is in the front-back direction and the up-down direction.
The positioning of the cartridge 51 is performed so that the silver-containing member 53 in the cartridge 51 is easily densely packed, and the water injection in the cartridge 51 flows toward the rear side in the cartridge 51 along the bottom surface. This stabilizes the elution amount of silver ions.
As shown in FIG. 8B, the cartridge 51 is positioned so that a space is formed between the bottom surface 311a of the powder detergent accommodating portion 311 of the case 31 and the bottom wall 551e of the cartridge 51 (case body 551). Will be done. As a result, it is possible to prevent the detergent powder from being clogged (retained) by the cartridge 51, and to prevent the detergent powder from solidifying and preventing water from passing through. The space between the bottom surface 311a of the case 31 and the bottom wall 551e of the cartridge 51 is preferably 10 [mm] or more. At this time, since the bottom wall 551e of the cartridge 51 is an inclined surface, it is easy to secure a gap.

The positioning portion in the front-rear direction is composed of a groove extending in a direction orthogonal to the front-rear direction (here, the vertical direction), which is the positioning direction, and a ridge that fits along the groove.
As shown in FIG. 4, the groove 537a is formed on the cartridge 51 side, and the ridge 31b is formed on the case 31 side. The groove 537a is formed in, for example, the left wall 553b and the right wall 553c of the case lid 553, and is formed between the pair of ridge portions 537b. The ridge 31b is formed in the powder detergent accommodating portion 311 of the case 31.

The vertical positioning portion is composed of a first engaging portion extending in a direction orthogonal to the vertical direction (here, the front-rear direction), which is the positioning direction, and a second engaging portion that engages with the first engaging portion. Will be done. The first engaging portion is a ridge 31c formed in the powder detergent accommodating portion 311 of the case 31, and the second engaging portion is the lower end of the left wall 553b and the right wall 553c of the case lid 553 of the cartridge 51. It is composed of at least one (here, both) of the lower ends of the ribs 551f of the case body 551.

3. 3. Replacement of Cartridge (1) Removal Take out the case 31 of the detergent charging section 3 to expose all of the cartridge 51. Next, by lifting the eaves wall 553 g from below, the upper part of the cartridge 51 protrudes from the case 31, and the overhanging portion can be grasped and lifted upward to remove the cartridge 51.
Alternatively, the exposed bottom wall 551e and top wall 553e of the cartridge 51 can be removed by grasping them from the front side and lifting them upward.
The cartridge 51 can be easily removed by either method. At this time, the silver-containing member 53 is housed in the cartridge case 55 in a state where a desired elution amount cannot be secured (a predetermined amount remains) (in some cases, the silver-containing member is completely consumed). However, the cartridge 51 can be replaced without directly touching the silver-containing member 53.

(2) Mounting The cartridge 51 is positioned with respect to the cartridge installation area of the case 31. Positioning is performed so that the left and right grooves 537a of the cartridge 51 are located above the ridges 31b of the case 31, and the engaging portion 535 of the cartridge 51 is located above the connecting portion 317 of the case 31.
In this state, the cartridge 51 is lowered to engage the engaging portion 535 with the connecting portion 317 and bring the rib 551f of the cartridge 51 into contact with the ridge 31c of the case 31.
As a result, the cartridge 51 can be installed at a fixed position.
At the time of installation, since the eaves wall is 553 g, the orientation of the cartridge 51 is easy to understand and it is easy to install. Further, when the left and right grooves 537a of the cartridge 51 are positioned above the protrusions 31c of the case 31, the engaging portion 535 of the cartridge 51 is located on the connecting portion 317 of the case 31, so that the alignment can be easily performed.

4. Processing contents of the control unit (1) Overall The control unit 18 performs a washing step, a rinsing step, and a dehydration step according to the washing course received by the operation of the operation unit 171 of the user. Specifically, each step is performed by reading a program corresponding to the washing course from the storage unit 182 and executing it.

(1-1) Washing process The control unit 18 measures the weight of the laundry put into the rotary drum 12 with the weighing sensor 151, and in order to inject water corresponding to the measured weight, the first valve of the water injection control unit 164 And the second valve are opened and closed.
Specific control of water injection is as follows: the first valve is in the closed state, the second valve is in the open state, water is injected through the liquid detergent accommodating portion 312 for a predetermined time, the first valve is in the open state, and the second valve is in the closed state. Water is injected through the detergent powder accommodating unit 311 and the function-imparting unit 5, and when a predetermined amount of water injection is detected by the water level sensor 152 provided in the washing tub 11, the first valve is closed. ..
As the washing water used in the washing step, water in which silver ions are eluted (passed through the function-imparting unit 5) is often used.

When a predetermined amount of water is injected, the control unit 18 drives the motor 14 for a predetermined time (“washing”) and then drains the water. The detection of the predetermined time is performed by the timer 183 in the control unit 18, and the drainage is performed by opening the drainage control unit (third valve) 191. The drainage control unit 191 is closed during water injection and washing.
When the water level sensor 152 detects the discharge of washing water, the control unit 18 drives (dehydrates) the motor 14 again for a predetermined time. This completes the washing process.
The washing time of the washing course selected by the user, the amount of water corresponding to the weight of the laundry, and the like are stored in a table stored in the storage unit 182 in association with the washing course.

(1-2) Rinse process The control unit 18 controls the water injection control unit 164 to inject a predetermined amount of water according to the weight of the laundry weighed in the washing process, and drives the motor 14 for a predetermined time (“rinse”). After that, drain the water. The above series of water injection, driving, and drainage are performed once, and the rinsing is usually performed a plurality of times. The rinse other than the final rinse is referred to as "normal rinse", and the final rinse is referred to as "final rinse".
In normal rinsing, water injection is controlled by injecting water through the powder detergent accommodating portion 311 and the cartridge 51 with the first valve open and the second valve closed, and when the water level sensor 152 detects a predetermined amount of water injection, This is done by closing the first valve.
In the control of water injection in the final rinse, water is injected through the softener accommodating portion 313 with the first valve and the second valve open, and when a predetermined amount of water injection is detected by the water level sensor 152, the first valve and the first valve are controlled. This is done by closing the two valves.
As described above, in the normal rinse, water in which silver ions are eluted and does not contain a softener is used, and in the final rinse, water which does not contain silver ions but contains a softener is used.
The number of rinses in the washing course selected by the user, the rinsing time, the amount of water injection corresponding to the weight of the laundry, and the like are stored in association with the washing course in, for example, a table stored in the storage unit 182.

(1-3) Dehydration Step When the rinsing step is completed, the control unit 18 opens the drainage control unit 191 and drives the motor 14 for a predetermined time (dehydration). As a result, the dehydration process is completed and the washing operation is completed.

(2) Consumption of silver-containing member There is a need to know the consumption state (cartridge replacement time) of the silver-containing member 53 without checking the consumption amount of the silver-containing member 53. The control unit 18 manages the consumption of the silver-containing member 53, and notifies the user of the consumption state of the silver-containing member 53 via the notification unit 175 (lamp 175a). In other words, the control unit 18 notifies the replacement of the cartridge 51 containing the silver-containing member 53. When the cartridge 51 is arranged in the case 31 so that the eaves wall 511e can be visually recognized, the remaining amount of the silver-containing member 53 is difficult to understand, and the notification of replacement of the cartridge 51 is particularly effective, but the replacement of the cartridge 51 The control unit 18 for notifying the timing can be applied even when the silver-containing member 53 is visible.
The control unit 18 is used in an amount corresponding to a usable amount of the silver-containing member 53 after the replacement of the cartridge 51 and a usable amount corresponding to the amount of the silver-containing member used in the washing operation after the replacement of the cartridge 51. The usage status is determined from the amount. That is, when the usage amount exceeds or approaches the usable amount, it is notified.
The control contents of the control unit will be described below.

(2-1) Configuration The control unit 18 includes a storage unit 182 that stores a total consumption amount (K), which is the sum of the consumption amount of the silver-containing member 53 in a single washing operation and the consumption amount of the silver-containing member 53. In each washing operation, the addition means for adding the consumption amount (G) of the silver-containing member 53 consumed in the washing operation to the total consumption amount (K) stored in the storage unit 182, and the addition means in the washing operation. A determination means for determining that the total consumption amount (K) to which the consumption amount (G) of the silver-containing member 53 is added exceeds (or exceeds) a predetermined amount (R) is provided by the determination means. When it is determined that the total consumption amount (K) exceeds (or exceeds) the predetermined amount (R), the notification unit 175 (lamp 175a) notifies the consumption state.

(2-2) Processing contents (2-2-1) Main processing As shown in FIG. 10, when the control unit 181 is started by turning on the power of the washing machine X, the variables K, C, and the constant R are displayed from the storage unit 182. Is read (S1). Here, the variable "K" indicates the total consumption of the silver-containing member 53 due to the washing operation, and the variable "C" is a variable indicating whether or not the cartridge 51 has been replaced and the user has operated the reset button. Yes, for example, "0" indicates a state in which the reset operation has not been performed, and "1" indicates a state in which the reset operation has been performed. The constant "R" is a reference value indicating the consumption amount of the silver-containing member 53 at the time of replacing the cartridge 51. The cartridge 51 contains a predetermined fixed amount, and the reference value "R" is unchanged.
When the total consumption "K" is equal to or greater than the reference value "R"("Yes" in S2), the control unit 181 blinks the lamp 175a because it is time to replace the cartridge 51 (S3). It should be noted that the blinking lighting of the lamp 175a is notified that it is time to replace the lamp, and the lighting of the lamp 175a is notified that it is in a usable state.

The control unit 181 resets the total consumption of the silver-containing member 53 so far when the user replaces the cartridge 51 and operates the reset button by blinking the lamp 175a (“Yes” in S4). Therefore, the variable "K" is set to "0" (S5), the lamp 175a is turned on (S6), and the process proceeds to step S7.
Further, even if the user has not operated the reset button (“No” in S4) after blinking the lamp 175a in step S3, the process proceeds to step S7.
The operation of the reset button of the user is accepted at any time, and when there is a reset operation, the variable "C" is stored in the storage unit 182 as "1". That is, the reset reception in step S4 determines whether or not the variable "C" is "1".

When the control unit 181 receives the washing course desired by the user from the operation unit 171 (“Yes” in S7), the control unit 181 performs a washing operation corresponding to the washing course (S8). By carrying out the washing operation treatment described later, washing, rinsing and dehydrating are performed, and the water consumption L1 of the water used in the single washing operation received this time and containing silver ions is calculated.
The control unit 181 calculates the consumption amount “G” of the single silver-containing member 53 from the water consumption amount L1 calculated in step S8, stores it in the storage unit 182 (S9), and stores it in the storage unit 182. The sum added to the total consumption amount "K" is stored in the storage unit 182 as a new total consumption amount "K" (S10, S11), and the process ends.
The concentration of silver ions in the washing water and the rinsing water in the washing tub 11 is known in advance by a test or the like, and the consumption amount "G" is obtained by multiplying the concentration stored in the storage unit 182 by the water consumption amount L1. It is calculated by.

If the total consumption "K" is less than the reference value "R" ("No") in step S2, the control unit 181 has not yet reached the replacement time of the cartridge 51, and proceeds to step S6 to proceed to the lamp. Turn on 175a.

(2-2-2) Washing operation processing The control unit 181 performs a washing operation processing as shown in FIG.
That is, when the washing operation process is started, the control unit 181 reads the variable “N” from the storage unit 182 (S81) and clears the variables “L1”, “L2”, and “m” to 0 (S82).
The variable "N" is the number of rinses, and the variable "L1" is the amount of water consumed in the washing process. The variable "L1" is the total amount of water consumed in the washing step and all the rinse steps performed when the rinsing step is entered. The variable "L2" is the amount of water consumed in each single rinsing step of "N-1" normal rinsing. The variable "m" is a variable for counting the number of rinses.
Next, the control unit 181 performs washing corresponding to the washing course selected by the user (S83), and acquires the water consumption amount “L1” consumed in the washing (S84). Here, the water consumption amount "L1" is predetermined according to the weight of the laundry in the washing course selected by the user, and is stored in the table of the storage unit 182.

When the washing step is completed, the control unit 181 performs the rinsing step "N" times.
First, when the first normal rinsing step is completed (S85), it is determined whether or not the normal rinsing step is the final rinsing (S86), and if it is not the final rinsing (“No”), the first normal rinsing step is completed. The water consumption "L2" consumed in the rinsing process is acquired (S87). Here, the water consumption amount "L2" is predetermined according to the weight of the laundry in the washing course selected by the user, and is stored in the table of the storage unit 182.

The control unit 181 adds the acquired water consumption amount "L2" to the total water consumption amount "L1", adds 1 to the variable "m", stores these in the storage unit 182, and returns to step S85. ..
Perform the remaining normal rinsing process that is not the final rinsing, read out the water consumption "L2" in the normal rinsing process, add it to the total water consumption "L1", and add 1 to the variable "m". Then, it is stored in the storage unit 182 (S85 to S88).
In the case of the final rinsing step (“Yes” in S86), dehydration is performed in step S89, and the process proceeds to step S9 of the main process.

<Second Embodiment>
In the first embodiment, when the consumption of the silver-containing member 53 is controlled, the consumption amount of the silver-containing member 53 in the single washing operation is added, but the unused silver-containing member 53 is added for each washing operation. The consumption of a single washing operation may be subtracted from the weight. Hereinafter, the case of subtraction and management will be described as the second embodiment.

1. 1. Configuration The control unit 18 is stored in a storage unit 182 that stores the consumption amount of the silver-containing member 53 in a single washing operation and the remaining amount (K) of the silver-containing member 53, and a storage unit 182 for each washing operation. A subtraction means for subtracting the consumption amount (G) of the silver-containing member consumed in the washing operation from the remaining amount (K), and a subtraction means for subtracting the consumption amount (G) of the silver-containing member 53 in the washing operation. It is provided with a determination means for determining that the remaining amount (K) is less than (or less than or equal to) the predetermined amount (R), and the remaining amount (K) is less than the predetermined amount (R) by the determination means ( Or, when it is determined that the result is as follows), the notification unit 175 (lamp 175a) is notified of the consumption state.

2. 2. Processing details The main processing of the control unit will be described with reference to FIG. For the steps of the same processing as in the first embodiment, the same step numbers are used, and the description thereof may be omitted in some cases.
As shown in FIG. 12, when the control unit 181 starts by turning on the power of the washing machine X, the storage unit 182 replaces the variable "K" indicating the remaining amount of the silver-containing member 53 and the cartridge 51 by the washing operation. The variable "C" indicating whether or not the user has operated the reset button and the constant "R" indicating the reference value indicating the remaining amount of the silver-containing member 53 at the time of replacing the cartridge 51 are read (S101). When the remaining amount “K” is equal to or less than the reference value “R” (“Yes” in S102), it is time to replace the cartridge 51, and the lamp 175a blinks (S3).
In step S4, when the user is performing a reset operation (“Yes” in S4), the control unit 181 sets the material of the silver-containing member 53 to an unused initial value (S105), and sets the lamp to an unused initial value. Turn on (S6).

The control unit 181 performs the washing operation of the washing course received from the user (steps S7 and S8), calculates the consumption amount “G” of the silver-containing member 53 from the water consumption amount L1 calculated in step S8, and stores the storage unit. It is stored in the storage unit 182 (S9), and what is subtracted from the remaining amount "K" stored in the storage unit 182 is stored in the storage unit 182 as a new remaining amount "K" (S10, S11).

<Third Embodiment>
In the first and second embodiments, the temperature of the water injection is not taken into consideration when controlling the consumption of the silver-containing member 53, but the consumption amount may be calculated in consideration of the temperature of the water injection. As a result, highly accurate notification of cartridge replacement can be performed.
Hereinafter, the case of managing in consideration of the water temperature will be described as the third embodiment.

1. 1. Configuration The control unit contains silver in a single washing operation according to the water temperature sensor that detects the water temperature injected into the washing tub 11 and the water temperature detected by the water temperature sensor with respect to the control unit 18 of the first embodiment. Adjusted consumption amount "G1" treated as consumption amount of silver-containing member 53 in a single washing operation, which is adjusted by multiplying consumption amount "G" by a water temperature coefficient "j" that increases or decreases the consumption amount "G" of member 53. Is further provided with a calculation means for calculating.

2. 2. Processing contents (1) Example 1
The main processing of the control unit will be described with reference to FIG.
Here, the case where the temperature is considered by using the first embodiment in which the consumption amount is added will be described, but the second embodiment in which the consumption amount is subtracted can also be used.
In step S201, the control unit acquires water temperature data from the water temperature sensor and reads out the water temperature coefficient “j” corresponding to the acquired water temperature from the storage unit 182 (S202). Multiplying the read water temperature coefficient "j" by the consumption amount "G" stored in step S9 is used as the adjusted consumption amount "G1" (S203), and is added to the total consumption amount "K" (S204).

(2) Example 2
In Example 1, water temperature data and the like were acquired in the main process, but it may be performed in the washing operation process, and will be described with reference to FIG.
In step S211 the control unit acquires water temperature data from the water temperature sensor, reads the water temperature coefficient “j” corresponding to the acquired water temperature from the storage unit 182 (S212), and stores the read water temperature coefficient “j” in step S84. Multiply the calculated water consumption amount "L1" to obtain the adjusted water consumption amount "L1" (S213).
In step S221, the control unit acquires water temperature data from the water temperature sensor, reads the water temperature coefficient “j” corresponding to the acquired water temperature from the storage unit 182 (S222), and stores the read water temperature coefficient “j” in step S87. Multiply the calculated water consumption amount "L2" to obtain the adjusted water consumption amount "L2" (S223).

Although the first to third embodiments have been described above, the present invention is not limited to these embodiments, and for example, the following modifications may be used. Further, the embodiment, the modified example, and the modified example may be combined.
Further, even if there is an example not described in the embodiment or the modified example, or a design change within a range not deviating from the gist, it is included in the present invention.

<Modification example>
1. 1. Function-imparting unit (1) The function-imparting unit 5 was installed in the case 31 of the detergent charging unit 3, but may be installed separately (independently) from the detergent charging unit 3. In this case, it can be carried out by providing a function-imparting section in a water injection channel different from the water injection channel to the detergent injection section. In this case, the washing tub can be filled with water having only the function.
