It has a shape and serves as an extension portion 40b.

Although not shown, the main body 1 is provided with a control device, which is composed mainly of a microcomputer, for example, and controls the entire washing machine including the water supply mechanism 8 . The control device operates the water supply valves 20, 21, 21, 21 of the water supply valve unit 12 based on input signals from various sensors and pre-stored control programs according to the operation course set by the user on the operation panel 5. It controls the pump 30 of the automatic loading device 17, the drum motor, the drain valve, the drying unit, and the like. Thus, a washing operation consisting of a washing process, a rinsing process, and a dehydration process, and a drying operation are automatically executed. The details of each process of the washing operation and the drying operation are well known, so the explanation is omitted here.

In the present embodiment, when executing the washing operation, the user either automatically puts in the detergent and softener with the automatic put-in device 17, or manually uses the storage case 18 of the manual put-in mechanism 19 for one time. On the operation panel 5, it is possible to select whether to put in detergent or fabric softener. When the user selects manual input, the user stores a required amount of powder detergent or liquid detergent in advance in the manual detergent storage portion 18a of the storage case 18 when starting the washing operation. When a softening agent is used, a required amount of softening agent is put into the manual softening agent container 18b together with the detergent.

When manual input of detergent and fabric softener is selected, the control device supplies water for the washing process through the manual detergent water supply valve 21 . When water is supplied in the final rinsing process, water is supplied by opening the manual softener water supply valve. On the other hand, when the automatic injection of detergent and softener is selected, the automatic injection device 17 supplies the required amount of detergent to the discharge part before the start of water supply in the washing process, and the automatic water supply valve 20 to turn on the water supply. In addition, before the final rinsing process, the automatic supply device 17 supplies a required amount of softener to the supply section, and the automatic water supply valve 20 is opened to supply water. The water supply is performed so that the water level in the water tank reaches a predetermined water level corresponding to the amount of laundry on the basis of the result of detecting the amount of laundry in the drum.

Next, the action and effect of the washing machine having the above configuration will be described. When the detergent and fabric softener are to be manually added in executing the washing operation, the user selects manual input on the operation panel 5 . At the same time, the drawer-type storage case 18 is pulled out to store the necessary amount of detergent, that is, powder detergent or liquid detergent in the manual detergent storage portion 18a, and the required amount of softener is put into the manual softener storage portion 18b. do. After closing the front door 26 and storing the storage case 18 in the water injection case 13, the washing operation is started.

When the washing operation is started, the control device controls each mechanism of the washing machine to automatically perform the well-known washing operation consisting of washing, rinsing and spin-drying processes. In the washing process, water is first supplied to the tank up to a predetermined water level. If manual detergent input is selected, the controller opens the manual detergent water supply valve 21 to start washing. Execute water supply for the stroke. When the manual detergent water supply valve 21 is turned on, water from the water supply source passes through the detergent flow path 27 of the manual water supply path 15 and reaches the outlet side end 27b on the left side of the sprinkler plate 35 .

Then, the water flows down from a plurality of watering holes 38 provided in the watering plate 35 toward the manual detergent storage portion 18a of the storage case 18, and water is sprayed like a shower. The water dissolves the detergent contained in the manual detergent container 18a, becomes washing water, flows to the bottom of the water injection case 13, and is supplied into the water tank through the water supply hose. When water is supplied to a predetermined water level in the water tank, the manual detergent water supply valve 21 is turned off, and the washing process is performed. In the subsequent water supply during the final rinsing process, the manual softener water supply valve is opened to supply water. A detailed description of the operation of the automatic injection device 17 when automatic injection of detergent and softener is selected will be omitted.

Here, in the present embodiment, at the outlet side end portion 27b of the sprinkler plate 35, a plurality of sprinkler holes 38 arranged in the front-rear direction on the left and right sides are formed into semicircular shapes with only the outer half portions open. It is made into the form which has the opening part 39b. At this time, when the water flows down from the water spray hole 38 to the manual detergent container 18a, it tends to flow outward, that is, toward the inclined rib 40 side. Then, the water is guided along the inclined surface 40a of the inclined rib 40, and is sprayed obliquely toward the outside, that is, toward the left and right inner wall surfaces of the manual detergent container 18a. It can be brought into contact with the inner wall surface of the manual detergent container 18a.

Therefore, even if the left and right inner wall surfaces of the manual detergent containing portion 18a are erected at an angle of approximately 90 degrees in order to secure the volume, water can be effectively applied to the inner wall surface of the manual detergent containing portion 18a. Water can be supplied, and water can be supplied while easily washing away the detergent adhering to the inner wall surface. As a result, according to this embodiment, the manual input mechanism 19 for supplying the laundry treatment agent in the storage case 18 into the water tank together with the water supply is provided, and the inner wall surface of the manual detergent storage portion 18a of the storage case 18 is provided.

In particular, in this embodiment, the lower surface of the sprinkler plate 35 is provided with vertical ribs 41 extending downward so as to connect the inclined ribs 40 in the row direction. As a result, the water guided by the slanted ribs 40 falls outward while being further guided outward by the vertical ribs 41, so that the inner wall surface of the manual detergent storage portion 18a of the storage case 18 is more sprayed with water. By making it active, it is possible to further suppress the detergent from remaining.

Further, in the present embodiment, an extending portion 40b that spreads sideways is provided at the tip portion of the inclined surface 40a of each inclined rib 40. As shown in FIG. As a result, the water guided along the inclined surface 40a of the inclined rib 40 is sprayed laterally, i.e., in a direction that spreads in the front-rear direction at the extending portion 40b at the leading end of the housing case 18. The water can be sprayed over a wider area on the inner wall surface side of the manual detergent container 18a, which is more effective.

Each of the water spray holes 38 is formed in a semicircular shape by closing the inner half of the tip of a projecting cylindrical portion 39 projecting from the lower surface of the water spraying plate 35 with a blocking plate portion 39a. A semi-circular opening 39b is provided. As a result, the water passing through each watering hole 38 hits the portion blocked by the blocking plate portion 39a and is discharged obliquely through the semicircular opening 39b. That is, the amount of detergent toward the inner wall surface of the manual detergent storage portion 18a of the storage case 18 can be increased. Therefore, it is more effective in directing water to the outside than when the sprinkler plate 35 is simply perforated in a semi-circular shape.

Further, although detailed description is omitted, the sprinkler plate 35, in this case the passage forming member 25 as a whole, is manufactured by molding a plastic material. In the water sprinkling hole 38 having the protruding cylindrical portion 39 as described above, it is possible to form a structure in which the mold can be removed without providing a slide mold or the like in plastic molding.
