As the detergent charging means, one that automatically allows the stored detergent to be poured several times, or one that allows one batch of the detergent to be thrown in can be used. As a means for supplying water, a configuration in which the detergent to be added is stored in advance in the water supply path and is washed away with water when water is supplied as washing water is widely used.

  However, this type of detergent charging means is generally provided in a top cover that forms the upper part of the main body. For example, a water injection case having a water supply means on the back side of the laundry entry / exit port of the top cover is provided. A unit container that is disposed and formed therein with a detergent reservoir, a bleach reservoir, and the like is slidable in and out in the front-rear direction. Accordingly, after the detergent or bleach is stored once in the unit container drawn forward, the unit container is stored in the water injection case, and when the operation is started, the supply of washing water is started. The detergent is supplied into the water tank through the case and the detergent reservoir, and at this time, the detergent is also thrown into the water (see, for example, Patent Document 1).

In addition, as a means for supplying detergent in accordance with water supply, a structure in which a detergent case for storing and storing the detergent from the top is provided and an openable / closable lid is provided at the upper surface opening of the case (for example, , See Patent Document 2).

  Therefore, in the configuration in which the unit container having the detergent storage portion, the bleach storage portion and the like is inserted and removed in the front-rear direction as described in the former Patent Document 1, it is necessary to secure a front drawing space, and thus the unit container Is preferably arranged in the back of the upper part of the main body. However, the site where the user stores and stores the detergent in advance is an operation separated from the user, making it difficult to operate and easily spilling the detergent.

  On the other hand, if it is set as the detergent case which can store and store a detergent from the upper part as described in the latter patent document 2, it can be provided in the appropriate position of a main body upper part, without receiving a big restriction | limiting in arrangement conditions. . However, this is a simple structure as in the case of one type of detergent means, and in the case where a plurality of types of laundry treatment agents such as bleaching agents and softening finishes can be supplied, the detergent case Since the water supply means into the case also forms a plurality of water channels, it is not easy to provide at a desired position due to restrictions on the arrangement conditions.

  The present invention has been made in view of the above-described circumstances, and therefore, the object thereof is good operability for storing and storing detergent with respect to a detergent case having a plurality of storage portions, and is easy to install in a compact configuration. The present invention also provides a washing machine equipped with an excellent detergent charging means.

In order to achieve the above object, the washing machine of the present invention stores and stores the detergent in a container-like detergent case that is connected to the water supply path, and can supply the detergent together with the water supplied to the water tank. In the case where the detergent charging means is provided, the detergent charging means is provided in a rectangular container-shaped detergent case having an opening that allows the detergent to be stored from above, and the detergent case is provided inside the detergent case. An inner case that is partitioned and formed in the longitudinal direction of the detergent case in an array, and has a water supply receiving port for each storage section on the side wall in the longitudinal direction, and the detergent can be discharged together with water when water is supplied to the storage section; A water channel having a water supply port corresponding to the water supply receiving port is provided in the longitudinal side wall of the detergent case, and water can be supplied to each storage part of the inner case through the water supply port and the water supply receiving port. And, wherein the water channel is to mainly characterized in that provided sidewalls integrally of the detergent case.

According to the above means, since the detergent can be stored and stored in each storage part of the inner case from above the detergent case, a space space ahead is required compared to the conventional type that draws forward. And can be provided with a simple configuration. In addition, even when the detergent case is provided on the upper part of the main body, for example, the installation site can be easily set without being restricted by the above space restrictions, and the detergent can be stored by a simple operation from above. There is no risk of spilling. Furthermore, since the water channel having a water supply port corresponding to the water supply port for supplying water to the reservoir of the inner case is provided integrally on the side wall in the longitudinal direction of the detergent case, the entire detergent case including the water channel can be configured compactly. together with the hose (pipe) can reduce the connection portion, such as, Ri correspondingly a Guaranteed it also water leakage, yet practical effect of such integral structure of the water channel is also effective to reinforce the mechanical strength of the side wall A washing machine having

Hereinafter, one embodiment in which the present invention is applied to a drum type washing machine will be described with reference to FIGS.
6 is a perspective view showing the external configuration of the entire washing machine, FIG. 7 is an enlarged perspective view of the main part, and first, based on these drawings, 1 is a washing machine body forming an outer shell, Although a detailed description is omitted, a drum (not shown) that can rotate around a horizontal axis, a drive mechanism (not shown) that rotates the drum, and a cylindrical shape that contains the drum and is elastically supported A water tank 2 is provided, and the water tank 2 stores wash water such as tap water and can be drained.

  However, the outer shell portion of the main body 1 includes a rectangular box-shaped outer box 3 and a top cover 4 that is attached so as to cover the upper surface thereof. The top cover 4 opens and closes a laundry inlet. As will be described in detail later, the lid 5 is provided with a detergent charging means 6 on the left side, an operation panel 7 on the right side, and a hose connection port 8 for supplying tap water to the rear side, and a pump. A hose connection port 9 for absorbing water (bath water) is provided, and can be supplied into the water tank 2 as washing water. The lid 5 has a so-called bi-foldable structure in which the rear end portion is pivotally supported so that the lid 5 can be bent at a substantially central portion.

  The specific configuration of the detergent charging means 6 will be described with reference to FIGS. 1 is a side view in which a principal part of the detergent charging means 6 is cut away, FIG. 2 is a longitudinal front view, FIGS. 3 and 4 are exploded perspective views as seen from different directions, and FIG. 5 is a side view of the principal part. In particular, FIG. 3 also discloses water supply means as washing water.

  First, FIG. 7 shows an open case lid 11 constituting the detergent charging means 6 and a detergent case 10 that is opened and closed by the case lid 11 and stores the detergent therein. As will be described later, a detergent or the like provided in the middle of the water supply path can be supplied into the water tank 2 together with water supply, and is disposed in the top cover 4 with the upper surface opened to the outside. The case lid 11 can be opened and closed.

And as a water supply means to the above-mentioned water tank 2, it is equipped with the water supply valve unit 12 which supplies a tap water, and the pump apparatus 13 which supplies bath water especially as disclosed in FIG. As will be described later, it is connected to the detergent case 10, and as shown in FIG. 7, the hose connection ports 8 and 9 face outward and are arranged at the rear part in the top cover 4.
Among them, the water supply valve unit 12 is an integrated unit of three valve functions, includes the first to third water supply valves 14 to 16, and is configured to share the above-described hose connection port 8.

  The specific configuration of the detergent charging means 6 connected to such water supply means will be described below. The detergent case 10 of the detergent charging means 6 has a rectangular container shape with an open top surface. The case body 17 includes a water channel member 18 that is integrally attached and fixed to the longitudinal side wall 17a. The water channel member 18 forms a plurality of water channels as will be described later. 5 shows a side view of the detergent case 10 to which the water channel member 18 is attached and fixed.

  More specifically, the case main body 17 is provided with, for example, four rectangular openings 19a to 19d in a horizontal arrangement at the same height as the water supply port 19 at the upper portion of the side wall 17a. As is apparent from FIG. 1, a bottom surface inclined downward is formed, and a drain port 20 is formed on the rear wall 17c side at the lowermost end. Further, two valve connection ports 21 and 22 are integrally provided on the rear wall 17c side in the vertical direction. However, the valve connection ports 21 and 22 do not directly pass through the rear wall 17c, and open to face the side wall 17a in a substantially right angle direction, thereby forming passages 21a, 22a, and 25a that are partitioned into three upper and lower sides. ing.

Of these, the lowermost passage 22a communicates with the valve connection port 22, the upper passage 21a communicates with the valve connection port 21, and the remaining uppermost passage 25a is merely bag-shaped. The passage 13 communicates with the device 13.
However, the water channel member 18 is attached and fixed to the side wall 17a side to constitute the detergent case 10. The water channel member 18 has the lower surface side facing forward (leftward in the figure) in FIG. 3 (and FIG. 5). It has a so-called stepwise taper shape, and has a flat shape in which the entire surface on the side fixed to the side wall 17a is open.

As shown in FIGS. 4 and 5, the water channel member 18 is formed with a plurality of water channels 23 that are partitioned in the vertical direction, and in this embodiment, three water channels 23 a to 23 c arranged in the vertical direction are formed. Both are formed extending in the front-rear direction. Accordingly, in this embodiment, the water channel 23 having a common cross-sectional area having a square hole shape is formed by mounting and fixing the water channel member 18 having the above-described configuration on the side wall 17a.
Moreover, as the water channel configuration in a state where the water channel member 18 is attached and fixed to the case body 17, the uppermost water channel 23c of the water channel 23 is a water channel including the opening 19d on the tip (front) side thereof. The middle water channel 23b includes two openings 19b and 19c, and the lowermost water channel 23a includes a water channel configuration including the opening 19a.

  Accordingly, in the water channel 23, three water channels 23a, 23b, and 23c are arranged adjacent to each other in the longitudinal direction behind the base end portion. However, the number of water channels decreases toward the front, that is, first, the tip of the water channel 23c is moved. At the almost intermediate position, the two water channels 23a and 23b are arranged vertically, and only the water channel 23a is provided at a portion beyond the front end of the front water channel 23. Moreover, since these water channels 23 are arranged adjacent to each other without a gap, and the upper portion is at a certain position where the water supply port 19 is located, each water channel 23a, 23b, 23c is formed in a staircase shape that goes forward, The lower surface of the water channel member 18 also has a corresponding stepped shape.

  On the other hand, the rear end, which is the base end portion of each water channel 23a, 23b, 23c, is disposed opposite to each of the three passages 22a, 21a, 25a formed in the rear end portion of the case body 17 described above. A communicating waterway is constructed. From this configuration, the lowermost water channel 23a communicates with the second water supply valve 15 via the passage 22a and the valve connection port 22 toward the upstream side, and the middle water channel 23b communicates with the passage 21a and the valve connection port 21. Then, it communicates with the first water supply valve 14.

  On the other hand, the uppermost water channel 23c is disposed opposite to the bag-shaped passage 25a, so that the pump water (bath water) from the pump device 13 (refer to FIG. 3) is not used for water supply from the water supply valve unit 12. Water supply is possible. That is, as shown in FIGS. 4 and 5, a pump water supply port 25 is provided at the rear end portion of the water channel member 18, to which the discharge port of the pump device 13 is connected, and the pump water supply port 25 is connected to the water channel through the passage 25a. 23c.

Incidentally, a priming water supply port 24 (see FIG. 4) having a small diameter is formed at the rear end portion of the water channel member 18 below the pump water supply port 25. This is connected in a pump casing (not shown) of the pump device 13 and communicated with the middle water passage 23b and the passage 21a, and is supplied in advance as priming water for the pump device 13 when water is supplied using the passage 21a. It is intended to be stored.
Moreover, in FIG. 3, the 3rd water supply valve 16 is used as a water supply means for the water cooling of the dehumidifier added to the drying mechanism which has the warm air means which is not shown in figure, The description is abbreviate | omitted.

Therefore, as the means for fixing the water channel member 18 to the case main body 17, in the present embodiment, these are made of plastic, and are integrally fixed using vibration welding means. For this reason, as shown in FIG. 3, a slightly protruding joint rib 26 corresponding to the water channel structure of the water channel member 18 is formed on the side wall 17 a of the case body 17 without interruption, thereby facilitating vibration welding with the water channel member 18. And can be joined in a watertight manner (see FIG. 2).
The integral fixing of the water channel member 18 is effective for reinforcing the mechanical strength of the side wall 17a. Further, a plurality (at least two rows) of ribs 27a and 27b are formed in parallel around the upper surface of the case main body 17 as the detergent case 10, and the inner ribs 27a thereof have notches 28 at appropriate positions. Is forming.

  Further, as shown in FIG. 4, a plurality of engaging ribs 29 are vertically provided on the side wall 17d of the case body 17 on the side opposite to the water channel of the detergent case 10, and the lower end thereof has an inverted U-shape or an inverted shape. A groove-shaped engaging portion 29a having a V-shape is formed. This shows that the detergent case 10 is a part of the main body 1 that is attached and supported by engaging the arcuate flange 3a at the top of the outer box 3 as shown in the figure. Will be described in detail with reference to FIG. Such a plurality of engaging ribs 29 are also effective for reinforcing the side wall 17d.

  In contrast to the detergent case 10 having such a configuration, an internal case 30 that can be attached and detached is provided in the present embodiment. The outline of the inner case 30 is a rectangular container having an open upper surface, and the interior is partitioned into a plurality of reservoirs so that detergent or the like can be stored. As specifically shown in FIG. 1, this storage portion is divided into a powder detergent storage portion 31, a liquid softening agent storage portion 32, and a liquid bleach storage portion 33 in the present embodiment. When water is supplied to the reservoir, it has a function that allows it to be discharged (injected) together with water.

However, in the longitudinal side wall 30a of the inner case 30, water supply that is opened slightly larger than this at positions corresponding to the four openings 19a to 19d provided in the longitudinal side wall 17a of the detergent case 10. In the state where the receiving openings 34a to 34d are formed and the inner case 30 is mounted in the detergent case 10, these are matched and penetrated to enable water supply.
Further, the bottom portion 30b of the inner case 30 in the mounted state is disposed in a state having a gap with respect to the bottom portion 17b of the detergent case 1 as is apparent from the sectional view of FIG. It is possible.

  Hereinafter, a more specific configuration will be described. First, as shown in FIG. 1, the detergent storage portion 31 disposed at the rearmost among the plurality of storage portions is inclined downward toward the rear (back) as shown in FIG. 1. A large discharge port 35 is formed in the rear wall 30c at the lowest end (see also FIG. 4). And this detergent storage part 31 is divided by the partition wall 36 from the adjacent finishing agent storage part 32, and has two water supply receiving ports 34c and 34d among the four water supply receiving ports 34 mentioned above. The configuration is as follows. The powder detergent is dropped from above and stored on the bottom wall portion where the amount of detergent for one wash is inclined. In this case, there is no problem even if a part of the detergent spills from the outlet 35 to the detergent case 10 side.

  Next, the soft finish storage section 32 will be described. The soft finish storage section 32 is partitioned by a hollow partition wall 37 between the adjacent bleach storage section 33, and a siphon mechanism 38 is provided as a soft finish discharge means on the bottom wall portion. And has one water supply port 34b at the upper part in the compartment. However, the siphon mechanism 38 has a simple configuration that is generally employed, and is provided with a cylindrical inner cylinder portion 38a penetrating from the bottom wall portion and covering the outer periphery with a gap. The upper cylindrical opening 38 is configured to be lower than the partition walls 36 and 37.

  In addition, a plurality of ribs 38c are provided on the outer peripheral side of the inner cylinder part 38a, and this serves to ensure and fit the gap with the outer cylinder part 38b. Further, the collar portion 38d formed on the upper portion of the outer cylinder portion 38b serves as a guideline (limit) for the amount of the soft finish normally dropped from above, and of course the upper end opening of the inner cylinder portion 38a. It is provided at a lower level so that the soft finish does not inadvertently flow out or be stored unnecessarily.

And the bleaching agent storage part 33 arrange | positioned foremost is equipped with the siphon mechanism 38 same as the discharge means of the said softening agent storage part 32 in the bottom wall part, and the said water supply located in the forefront in this division upper part A receiving port 34 is provided.
However, the above-described hollow partition wall 37 is overflowed when an overflow port 39 is formed in the upper part on the bleach storage part 33 side and the water supply amount exceeds the drainage performance from the siphon mechanism 38. The bleach solution can flow down from the overflow port 39 to the bottom 17b of the detergent case 10 and be discharged from the drain port 20.

  A bowl-shaped water shielding cover 40 is attached to the upper part of the inner case 30 having such a configuration. As shown in FIGS. 1 and 3, the water shielding cover 40 is mainly composed of a rectangular opening frame portion 41 and a flange portion 42, and the opening frame portion 41 is provided in each of the storage portions 31 to 33 at the three locations. Corresponding rectangular opening frame portions 41a, 41b, and 41c are provided, and the flange portion 42 has a configuration in which flange portions 42a to 42c that incline inwardly from the periphery of the respective frame portions 41a to 41c are protruded. Become.

  Therefore, in a state in which the water shielding cover 40 is attached to the upper surface of the inner case 30, the flanges 42 a to 42 c are inward so as to cover the inner peripheral edge of the upper end opening of the inner case 30 as shown in FIGS. 1 and 2. In particular, the drooping dimension of the flange on the side of the water supply receptacles 34a to 34d is set to a length that is equivalent to or slightly drooping to these water supply receptacles 34, so as to be a so-called opposed arrangement. Yes.

In FIG. 1, a water supply valve unit 12 of water supply means is directly attached to the detergent case 10 described above. That is, three vertical and horizontal mounting bosses 43a, 43b, 43c (see FIG. 4) project from the rear wall 17c side of the case body 17, and the discharge ports of the first and second water supply valves 14, 15 are provided. These parts are integrally fixed by screwing them through the mounting bosses 43a, 43b, 43c in a state of being fitted and connected to the valve connection ports 21, 22, respectively.
Further, the drainage port 20 of the detergent case 10 is connected with a bellows-shaped water supply pipe 44 and is connected to an appropriate part of the water tank 2, so that the water supply valve unit 12 passes through the detergent case 10 in the middle. A water supply path to the water tank 2 is configured.

The means for attaching the detergent case 10 to the main body 1 will be described with reference to FIG. That is, FIG. 2 exemplifies a cross-sectional configuration in the soft finish storage portion 32, and the detergent case 10 is located in the top cover 4 and is vertically sandwiched between the top cover 4 and the outer box 3. It is attached and fixed in the state where it was done.
This attachment means has been described above as being configured to be supported from below by the flange 3a of the outer box 3 via the engagement rib 29 in FIG.

The detergent case 10 is supported by the upper flange 3a of the outer box 3 as described above, and a mounting portion 46 (see FIG. 3) formed on the opposite side is screwed to an appropriate stationary part of the main body 1. Further, in the groove formed by the ribs 27a and 27b on the upper surface of the detergent case 10, the fitting rib 4b hanging from the periphery of the opening end 4a of the top cover 4 is fitted, so-called labyrinth fitting.
Thereby, the detergent case 10 is supported from the outer box 3 in the lower part and supported by the top cover 4 from the upper part.

  If the top cover 4 is attached and fixed to the outer box 3 in this state, the detergent case 10 is also securely attached and fixed. Therefore, as a means for attaching the top cover 4 to the outer box 3, similar engagement ribs 45 project from the top cover 4 side so as to alternately overlap with the engagement ribs 29 on the detergent case 10 side. A groove-like engagement portion 45a is formed at the bottom end of the suspension.

  Accordingly, these engagement ribs 29 and 45 are arranged so as to overlap when seen from the front and rear direction as is apparent from FIG. 2, and the upper flange 3a of the outer box 3 is engaged with the substantially matching engagement portions 29a and 45a from below. Although not shown, the top cover 4 and the outer box 3 are screwed at an appropriate small number of places, and are securely fixed in that position. Thus, the detergent case 10 is in the top cover 4 and is fixedly attached to the top cover 4 and the outer box 3 so as to be sandwiched vertically.

  Then, the inner case 30 is inserted into the detergent case 10 from the opening end 4 a of the top cover 4. In this case, the upper end flange 30d of the inner case 30 is positioned by engaging with the upper surface of the fitting rib 4b projecting downward from the opening end 4a, and the water supply port 19 and the water supply receiving port 34 described above are positioned. Get consistent communication status. In addition, since the water supply receiving port 34 is formed to be slightly larger, the communication state between the two can be ensured.

  Accordingly, the water shielding cover 40 is detachably attached and fixed to the inserted and supported inner case 30 so as to cover the peripheral edge of the opening. That is, the outer peripheral portion of the opening frame portion 41 is inserted into the opening end portion 4a of the top cover 4, and a plurality of protrusions 47 formed on the outer surface of the opening frame portion 41 are elastically engaged. Further, the tubular portion 48 is provided to hang down at the base end portion side of the flange portion 42, and a plurality of protrusions 49 are formed at the lower end portion of the outer surface, and the protrusions 49 are formed at predetermined portions of the inner case 30. The plurality of engaging holes 30e are elastically engaged with each other.

Accordingly, the water-impervious cover 40 has the upper protrusion 47 engaged with the top cover 4 and the lower protrusion 49 engaged with the inner case 30, so that the water-proof cover 40 is attached to the inner case 30 and the inner case 30 is attached. Also serves as fixing. Moreover, the substantially vertical cylindrical portion 48 is fitted to the inner peripheral surface of the opening of the inner case 30 to suppress the movement in the horizontal direction , and the cylindrical portion 48 is on the peripheral side of the entire outer periphery of the opening frame portion 41. It is formed in the portion, and the entire water shielding cover 40 is also reinforced. Moreover, in the collar part 42, it is arrange | positioned in the water supply receptacle 34 side in the position facing this receptacle 34 in a horizontal direction.

  Further, FIG. 2 discloses a case lid 11 in a state where the upper portion of the detergent case 10 is closed. The case lid 11 is rotatably supported by a top cover 4 with a shaft portion 11c formed at one end on the left side, and an elastic engagement piece 11a is formed on the other end on the right side. The case lid 11 is pivotally supported so that it can be opened and closed.

Further, in order to facilitate the opening operation of the case lid 11, as shown in FIG. 7, a part of the opening end 4a of the top cover 4 is cut out to form a recess 4c, and a finger is inserted from the recess 4c. The protruding piece 11b on the free end side of the inserted and closed case lid 11 can be lifted upward. Further, the water shielding cover 40 can be taken out from the state in which the case lid 11 is opened by removing the elastically engaged projections 47 and 49, and therefore the inner case 30 can also be taken out.
In addition, although the protrusions 47 and 49 were provided in two different places on the upper and lower sides as elastic engagement means of the water shielding cover 40, this is also effective with only one of the protrusions.

Next, the operation of the drum type washing machine provided with the detergent charging means 6 will be described.
First, the laundry function will be outlined. As is well known, the “washing”, “rinsing” and “dehydration” processes are automatically executed, and the drums (not shown) are driven to rotate under appropriate rotation control. In the case of having a drying function, it is selectively executed and hot air is blown into the drum. However, in practice, tap water or the like is supplied as washing water and hot air for drying is blown into the water tank 2 containing the drum.

Therefore, when washing is started, when washing is started, water is supplied to the water tank 2 from the water supply valve unit 12 serving as water supply means, and detergent from the detergent input means 6 provided in the water supply path is supplied. .
This detergent and other laundry treatment agents are supplied in advance and stored in the detergent case 10 before the start of operation. That is, in this embodiment, from the state in which the case lid 11 is opened, the detergent storage portion 31 as the storage portion of the inner case 30 stores a single powder detergent, and the soft finish storage portion 32 is in a liquid state. The soft finish and the bleaching agent storage unit 33 store a liquid bleaching agent for one time, with the amount reaching the collar 38d as a limit. As is well known, the detergent and softener are usually put together with water in the water tank 2 at the same time as “washing” and the bleaching agent in the “rinse” stage to finish the laundry as desired.

  Here, the charging process of the detergent and the like by the detergent charging means 6 of the present embodiment will be described. When tap water is used as the washing water, the first water supply valve 14 is opened first, and the water is stored in the detergent case. It passes through the 10 valve connection ports 21 from the passage 21a to the side wall 17a and flows into the water passage 23b. Since the water supply port 34b includes two water supply ports 34b and 34c, the water is supplied into the detergent case 10 from both water supply ports 34b and 34c.

However, as shown in FIG. 1, since the inner case 30 is mounted in the detergent case 10, water is introduced from the water supply inlets 34b and 34c in a communicating state, and the detergent storage portion 31 and the flexible finish corresponding thereto. Water is simultaneously supplied to the agent reservoir 32. When the water is supplied, even if the water is discharged inward vigorously, it is received by the flanges 42a and 42b of the water shielding cover 40 and directed downward, so that the collided water does not scatter to the upper periphery. .
And in the detergent storage part 31, it receives water supply, flows down to the detergent case 10 side from the discharge port 35 of an inclination lower end part, melt | dissolves some detergents, flows out of the drainage port 20, and passes through the water supply line 44, and a water tank 2 is inserted.

  On the other hand, the soft finish storage unit 32 receives water from the water supply receiving port 34b, obtains the guide action of the water shielding cover 40 in the same manner as described above, and water is stored in the soft finish storage unit 32. However, since a predetermined amount of the soft finish has already been stored, it is discharged from the siphon mechanism 38 after receiving a small amount of water. That is, when the water level rises and exceeds the upper end opening of the inner cylinder part 38a, the soft finish is discharged together with water by the siphon action, and therefore the soft finish storage part until the water level becomes lower than the lower end opening of the outer cylinder part 38b. It continues to be discharged until the water in 32 is almost gone. Thus, the soft finishing agent discharged together with the water flows down the inclined bottom portion 17 b of the detergent case 10, flows out from the drain port 20, and the soft finishing agent diluted with water passes through the water supply pipe 44 in the water tank 2. It is thrown into.

On the other hand, in the case of the liquid bleaching agent introduced at the time of “rinsing”, the second water supply valve 15 is opened, and the water reaches the water passage 23a through the valve connection port 22 and the passage 22a of the detergent case 10. Then, water is supplied to and stored in the bleach storage part 33 from the opening 19a located at the forefront and the water supply opening 34a of the inner case 30. This bleaching agent is also discharged together with water by the siphon mechanism 38 similar to the above-described soft finish, and is put into the water tank 2 in a diluted state.

By the way, when the remaining water of the bath is effectively used as the water supply means, the pump device 13 is driven to supply water. That is, one end of a hose (not shown) is connected to the hose connection port 9 facing the upper portion of the main body 1 and prepared so that bath water can be absorbed from the other end. Is opened and water is supplied.

Compared to the type that pulls out, the front space is not required, and a simple configuration can be provided. Accordingly, the top cover 4 which is the upper part of the main body 1 for providing the detergent case 10 can be easily set without being greatly restricted and has excellent installation properties, and thus the degree of freedom in designing and manufacturing is increased. Since the detergent can be stored by simple operation, there is no risk of spilling the detergent around.

Moreover, since the water supply into the detergent case 10 having a plurality of storage portions is performed from the plurality of water channels 23a to 23c formed on the same side wall 17a side, the water channel member 18 having the plurality of water channels 23a to 23c. In this embodiment, which is an assembling operation, the mounting and fixing by vibration welding can be integrated at one time, and the side wall 17a is the longitudinal side of the rectangular case main body 17, and the workability is very good and inexpensive and compact. Can be produced.
In addition, since the plurality of water channels 23a to 23c by the water channel member 18 are arranged adjacent to each other along the vertical direction of the side wall 17a of the detergent case 10, the size of one water channel protrudes in the horizontal direction. It can be suppressed, and further downsizing is possible, and it is effective for saving the space of the installation site.

Furthermore, by arranging the water channels 23a to 23c in a staircase pattern that goes forward, the corresponding water supply ports 34a to 34d can be formed at the same height position on the upper part of the detergent case 10, which means that the detergent case 10 can effectively utilize the internal volume, so that the volume of each storage section can be sufficiently secured, and can store a necessary amount of detergent and the like while being a compact detergent case 10 and receive a large amount of water supply. Also effective.
Further, in this embodiment, since the cross-sectional areas of the adjacent water channels 23a to 23c are made common, the turbulent flow of water can be prevented, the resistance can be reduced, and the necessary amount of water can be ensured without being greatly affected by fluctuations in water pressure.

  In this embodiment, an internal case 30 having a plurality of storage portions for storing and storing detergent and the like is provided, and the internal case 30 is detachably provided in the case main body 17 of the detergent case 10. A water shielding cover 40 was provided so as to cover the peripheral edge of the upper end opening of the. Specifically, the opening end 4a of the top cover 4 and the detergent case 10 were provided so as to be detachable using elastic engagement means. Accordingly, the water shielding cover 40 is elastically fitted and mounted while ensuring the fixing of the inner case 40 and also mounting and fixing the water shielding cover 40 itself.

  As a result, the water shielding cover 40 does not float due to water pressure at the time of water supply, and the water shielding cover 40 can be removed by hooking a finger while the case lid 11 is opened. Can be easily removed, and the internal case 30 and the detergent case 10 can be easily cleaned. And since the inner case 30 can be easily replaced as a part, it becomes possible to deal with different means for introducing other detergents and specifications. For example, when a liquid detergent is used in place of the powder detergent, it can be implemented with various modifications such as adopting an internal case using a siphon mechanism for such a reservoir.

  In addition, the collar portion 42 provided on the water shielding cover 40 serves as a guide function for directing the flow of water supplied to each storage portion in the downward direction, and prevents splashing of water to prevent water splashing upward. Can do. Therefore, even when the case lid 11 is opened during water supply, water does not jump out, and for example, a detergent can be replenished without any trouble. Moreover, the collar part 42 inclined inward can be reliably dropped into a predetermined storage part when storing and storing detergent or the like from above.

  The detergent charging means 10 provided in the top cover 4 was fixed by sandwiching the detergent case 10 between the top cover 4 and the outer box 3 up and down. In particular, as in the present embodiment, by using an attachment means that engages with the flange 3a on the upper portion of the outer box 3 via the engagement portions 29a and 45a of the engagement ribs 29 and 45, the screwing points are minimized. Thus, it is possible to securely mount and fix it while suppressing the free movement in the lateral direction, so that it can be easily disassembled and assembled and can be manufactured at low cost.

  Moreover, since the upper surface of the detergent case 10 is configured to be fitted with the top cover 4 in the labyrinth among the above mounting and fixing, water leakage from the fitting portion is prevented, and in particular, the fitting portion, particularly the top cover 4. This is effective for increasing the strength of the periphery of the open end 4a. In addition, among the plurality of ribs 27a and 27b provided for labyrinth fitting, the rib 27a located inward is provided with a notch 28, so that water that has entered between the ribs 27a and 27b does not flow. It returns to the inside of the detergent case 10 and does not leak out of the detergent case 10.
