The processing agent manual input device 20 has a function of receiving the supply of the laundry processing agent required for one washing operation from the user for each washing operation and supplying the entire amount of the laundry processing agent into the water tub 13 during the washing operation. have. In the case of this embodiment, the laundry treatment agent is, for example, powder or liquid detergent, softener, or the like. In the case of this embodiment, as shown in FIGS. 1 to 3, the processing agent manual input device 20 is provided inside the outer box 11 and above the water tank 13, and is provided near one side of the washing machine 10 in the left-right direction. It is In the case of this embodiment, the processing agent manual input device 20 is provided on the left side of the washing machine 10 .

Specifically, the processing agent manual injection device 20 is located on the left side of the operation panel 18 and is provided behind the processing agent automatic injection device 30 . Further, in this case, the processing agent manual input device 20 is provided at a position at least partially overlapping the operation panel 18 in the front-rear direction of the washing machine 10 . As shown in FIG. 5, the processing agent manual injection device 20 is provided in the middle of the water supply route 42 and constitutes a part of the water supply route 42 .

As shown in FIG. 5, the manual treatment agent charging device 20 is configured to have a water injection case 21 and a manual treatment agent case 22 . The water injection case 21 constitutes the outer shell of the processing agent manual injection device 20, and is made of, for example, resin and formed in a box shape. The upstream side of the water injection case 21 is connected to the water supply valve 17 , and the downstream side of the water injection case 21 is connected to the water tank 13 via the water injection hose 19 .

The manual treatment agent case 22 is made of resin, for example, and is configured in the shape of a container capable of storing the laundry agent for about one time. The manual processing agent case 22 is accommodated in the water injection case 21 and configured to be exposed to the outside of the outer case 11 by user's operation. The manual processing agent case 22 is provided at a position where it receives water supplied through the water supply valve 17 while being accommodated in the water injection case 21 . The manual treatment agent case 22 may be exposed to the outside of the outer case 11 by, for example, opening and closing a lid that covers the manual treatment agent case 22 provided in the outer case 11 . It may be configured to be exposed to the outside of the outer case 11 by being able to draw it out or by removing it.

When the laundry treatment agent is manually put into the water tub 13 for each washing operation, the user puts the laundry treatment agent for one time into the manual treatment agent case 22 in advance before starting the washing operation. In this case, the user exposes the manual processing agent case 22 to the outside by, for example, opening the lid covering the manual processing agent case 22 or pulling out or removing the manual processing agent case 22 . Then, the user puts the laundry treatment agent into the manual treatment agent case 22 with the manual treatment agent case 22 exposed to the outside.

After that, when the water supply valve 17 is opened during the washing operation, the water discharged from the water supply valve 17 is poured into the manual processing agent case 22 provided in the water injection case 21 . The water poured into the manual processing agent case 22 flows out from the manual processing agent case 22 and the water injection case 21 and is poured into the water tank 13 via the water injection hose 19 . At this time, if the laundry treatment agent is put into the manual treatment agent case 22 , the laundry treatment agent is flushed down into the water tank 13 together with the water flowing out from the manual treatment agent case 22 and the water injection case 21 . In this manner, water is poured into the water tub 13, and the entire amount of the laundry treatment agent stored in the manual treatment agent case 22 is put into the water tub 13 during the washing operation.

The processing agent automatic injection device 30 has a function of preliminarily storing the laundry processing agent for a plurality of times and automatically supplying a predetermined amount of the laundry processing agent to the water tub 13 over a plurality of washing operations. . In the case of this embodiment, as shown in FIGS. 1 to 3, the processing agent automatic injection device 30 is provided inside the outer box 11 and above the water tank 13, and is provided near one side of the washing machine 10 in the left-right direction. It is In this embodiment, the processing agent automatic injection device 30 is provided on the left side of the washing machine 10 in the same manner as the processing agent manual injection device 20 .

Specifically, the processing agent automatic injection device 30 is located on the left side of the operation panel 18 and is provided in front of the processing agent manual injection device 20 . In this case, the processing agent automatic injection device 30 is provided at a position at least partially overlapping the operation panel 18 in the front-rear direction of the washing machine 10 . In the case of this embodiment, the processing agent automatic injection device 30 is provided at a position where the entire operation panel 18 overlaps with respect to the front-rear direction of the washing machine 10 .

As shown in FIG. 5, the processing agent automatic injection device 30 is connected to an intermediate portion of a water supply path 42 from the water supply valve 17 to the water tank 13 . In this case, the processing agent automatic injection device 30 is connected downstream of the processing agent manual injection device 20 and upstream of the water tank 13 , that is, between the processing agent manual injection device 20 and the water tank 13 . In the case of this embodiment, the processing agent automatic injection device 30 is connected to an intermediate portion of the water injection hose 19, as shown in FIG. Further, the processing agent automatic injection device 30 may be connected to the water injection case 21 of the processing agent case 22 for manual operation, as shown in FIG.

The water supply route 42 does not pass through the processing agent automatic injection device 30 . That is, the processing agent automatic injection device 30 is not included in the water supply path 42 . This processing agent automatic injection device 30 directly injects a predetermined amount of laundry processing agent into the water supply path 42 without using the water flow discharged from the water supply valve 17 . As a result, the laundry treatment agent necessary for the washing operation can be put on the water flowing through the water supply path 42 and put into the water tub 13 .

As shown in FIGS. 3 and 5, the processing agent automatic dosing device 30 has an automatic detergent tank 311 and an automatic softening agent tank 312 as automatic processing agent tanks for storing laundry processing agents. The automatic detergent tank 311 stores detergent as a laundry treatment agent. The automatic softener tank 312 stores a softener as a laundry treatment agent. Both the automatic detergent tank 311 and the automatic softener tank 312 can store the laundry treatment agent used in multiple operations, and their capacity is larger than that of the manual treatment agent case 22 .

The detergent tank 311 for automatic use and the softener tank 312 for automatic use are arranged side by side in the width direction of the outer box 11, that is, side by side in the left-right direction. In this case, either of the automatic detergent tank 311 and the automatic softening agent tank 312 may be arranged on the left side or the right side, but user convenience can be enhanced by, for example, configuring as follows.

That is, since the automatic detergent tank 311 and the automatic softener tank 312 are provided inside the outer box 11 and above the water tank 13, as shown in FIG. It is easier to ensure the dimension in the height direction as it goes to. Therefore, if the automatic detergent tank 311 and the automatic softener tank 312 have the same size in the width direction, the tank arranged outside the center in the width direction of the washing machine 10 is arranged inside. It can have a larger capacity than the tank designed for it.

Here, generally, the amount of detergent used in the washing operation is greater than the amount of softener used. Therefore, by arranging the detergent tank 311 for automatic use outside in the width direction, the capacity of the detergent tank 311 for automatic use is made larger than that of the softener tank 312 for automatic use. According to this, it is possible to increase the capacity of the automatic detergent tank 311 that stores the detergent, which is consumed in large amount, out of the detergent and the softener. Therefore, it is possible to reduce the frequency with which the user replenishes the detergent, and as a result, it is possible to improve the user's convenience.

In this case, the bottoms of the automatic detergent tank 311 and the automatic softener tank 312 are formed along the outer peripheral surface of the water tank 13 in the circumferential direction and the front-rear direction of the water tank 13, as shown in FIGS. ing. That is, the bottom surfaces of the automatic detergent tank 311 and the automatic softener tank 312 are inclined or curved along the surface around the water tank 13 when viewed from the front, and along the slope of the water tank 13 when viewed from the side. downwards sloping rearwards. According to this, the capacity of the automatic detergent tank 311 and the automatic softener tank 312 can be made as large as possible.

The processing agent automatic injection device 30 also has piston pumps 321 and 322 and check valves 331 , 341 , 332 and 342 . These piston pumps 321 , 322 and check valves 331 , 341 , 332 , 342 supply a predetermined amount of the laundry treatment agent stored in the automatic treatment agent tanks 311 , 321 necessary for the washing operation to the water supply path 42 . It functions as an automatic injection mechanism for automatic injection. In this case, the piston pump 321 and check valves 331 and 341 correspond to the detergent tank 311 for automatic use, and the piston pump 322 and check valves 332 and 342 correspond to the softener tank 312 for automatic use. Note that the automatic loading mechanism is not limited to this configuration.

The input sides of the piston pumps 321 and 322 are connected to automatic processing agent tanks 311 and 312 via check valves 331 and 332, respectively. The check valves 331 and 332 open the paths only from the automatic processing agent tanks 311 and 312 to the piston pumps 321 and 322 side. The check valves 331 and 332 prevent the laundry treatment agent in the piston pumps 321 and 322 from flowing back into the automatic treatment agent tanks 311 and 312 .

The output sides of the piston pumps 321 and 322 are connected to the water supply path 42 via check valves 341 and 342, respectively. The check valves 341 and 342 open the path only from the piston pumps 321 and 322 to the water supply path 42 side. The check valves 341 and 342 prevent the laundry treatment agent supplied to the water supply path 42 and the water flowing through the water supply path 42 from flowing back into the piston pumps 321 and 322 .

The piston pumps 321 and 322 are configured to be driven by electric actuators such as motors and solenoids. The piston pumps 321 and 322 draw a certain amount of the laundry treatment agent stored in the automatic treatment agent tanks 311 and 312 into the piston pumps 321 and 322 by drawing the pistons. Then, the piston pumps 321 and 322 push out the laundry treatment agents drawn into the piston pumps 321 and 322 toward the water supply path 42 by pushing out the pistons.

In this case, the amount of laundry treatment agent extruded by one reciprocating motion of the piston is sufficiently smaller than the amount of laundry treatment agent used in one washing operation. Therefore, the washing machine 10 can adjust the predetermined amount of laundry treatment agent to be supplied during the washing operation by adjusting the number of times the pistons of the piston pumps 321 and 322 operate.

According to the embodiment described above, the drum-type washing machine 10 includes an outer casing 11, a water tank 13 provided inside the outer casing 11, a processing agent manual input device 20, a processing agent automatic input device 30, Prepare. The treatment agent manual input device 20 has a manual treatment agent case 22 capable of storing a single amount of laundry treatment agent. Insert into 13. The automatic treatment agent input device 30 has automatic treatment agent tanks 311 and 312 capable of storing laundry treatment agents for a plurality of times. is put into the water tub 13 during the washing operation. The processing agent automatic feeding device 30 is provided in the front portion of the outer case 11 .

Here, when the user works on the manual processing agent case 22 and the automatic processing agent tanks 311 and 312, the weight of the manual processing agent case 22 and the automatic processing agent tanks 311 and 312 increases. Also, the farther the work position is from the user, that is, the more the user's arm is stretched during work, the greater the load applied to the user's arm and the lower the workability. In this case, the manual processing agent case 22 is not so heavy because it stores only one laundry processing agent. Therefore, even if the working position of the manual processing agent case 22 is some distance away from the user, the effect on the decrease in workability is small.

On the other hand, unlike the manual processing agent case 22, the automatic processing agent tanks 311 and 312 can store the laundry processing agents necessary for multiple operations. That is, it is assumed that the processing agent tanks 311 and 312 for automatic processing can store, for example, one bottle of commercially available detergent or softener as they are. The automatic processing agent tanks 311 and 312 storing the laundry processing agent for multiple times are heavier than the manual processing agent case 22 storing the laundry processing agent for one time. Therefore, when the working position of the automatic processing agent tanks 311 and 312 is away from the user, the workability is greatly reduced.

Therefore, the processing agent automatic injection device 30 of the present embodiment is provided in the front portion of the outer case 11 . Therefore, the user can work at the front side position of the washing machine 10 when refilling the automatic processing agent tanks 311 and 312 with detergent or softener, for example. In other words, the user can work on the automatic treatment agent tanks 311 and 312 without having to extend his arm to the rear of the washing machine 10 . As a result, the workability of the automatic processing agent tanks 311 and 312 for the user can be improved.

The washing machine 10 also has an operation panel 18 . The operation panel 18 is provided on the front side of the upper surface of the outer casing 11 and receives user's operations. The processing agent automatic injection device 30 is provided at a position overlapping the operation panel 18 in the front-rear direction of the outer case 11 . According to this, the distances from the front end of the washing machine 10 to the operation panel 18 and the processing agent automatic injection device 30 are substantially the same. Therefore, the distance that the user stretches his/her arm when working on the processing agent automatic feeding device 30 and the distance that the user stretches his or her arm when operating the operation panel 18 are the same.

That is, since the user operates the operation panel 18 every time he or she drives the vehicle, it is assumed that the user is accustomed to operating the operation panel 18 . Therefore, the user can operate the processing agent automatic injection device 30 only by extending the arm by the distance equivalent to that of the operation panel 18 that the user is accustomed to operating. Therefore, according to this, it is possible to improve the operability of the processing agent automatic injection device 30 for the user.

Further, the processing agent manual input device 20 is provided near one side of the outer case 11 in the width direction. The processing agent automatic injection device 30 is provided in front of the processing agent manual injection device 20 and in the same direction as the processing agent manual injection device 20 with respect to the width direction of the outer casing 11 . According to this, first, since the processing agent automatic injection device 30 is provided near one side in the width direction of the outer case 11, the space inside the outer case 11 can be effectively utilized, and the processing agent automatic injection device The 30 automatic processing agent tanks 311 and 312 can be made as large as possible.

That is, the automatic processing agent tanks 311 and 312 of the processing agent automatic feeding device 30 are installed in the space between the outer case 11 and the water tank 13 inside the outer case 11 . In this case, as shown in FIG. 4, the space between the outer box 11 and the water tank 13 increases toward the outside in the width direction of the outer box 11, making it easier to secure a larger space. Therefore, according to this embodiment, the capacities of the automatic processing agent tanks 311 and 312 of the automatic processing agent charging device 30 can be made as large as possible.

Further, according to the present embodiment, the processing agent manual injection device 20 and the processing agent automatic injection device 30 are provided on the same side with respect to the width direction of the outer box 11, so that the user's workability is improved. can be improved. That is, the manual treatment agent injection device 20 and the automatic treatment agent injection device 30 have a common function of injecting the laundry treatment agent into the water tub 13 . Then, the user performs the common work of adding the laundry treatment agent to the manual treatment agent injection device 20 and the automatic treatment agent injection device 30 . If the installation positions of such common devices are significantly different, it is likely to confuse the user.

On the other hand, according to the present embodiment, the processing agent manual injection device 20 and the processing agent automatic injection device 30 are provided near the same side in the width direction of the outer case 11 . In other words, the processing agent manual injection device 20 and the processing agent automatic injection device 30 are arranged on the same lateral side as seen from the user. According to this, by concentrating the positions of the processing agent manual injection device 20 and the processing agent automatic injection device 30 near each other, user confusion can be avoided, and as a result, workability can be improved.

Furthermore, according to this embodiment, the processing agent automatic injection device 30 is provided in front of the processing agent manual injection device 20 . According to this, the distance from the user to the automatic processing agent tanks 311 and 312 can be made as short as possible. As described above, according to the present embodiment, it is possible to simultaneously increase the capacity of the automatic processing agent tanks 311 and 312 and improve the workability.

In addition, the processing agent automatic input device 30 has an automatic detergent tank 311 storing detergent and an automatic softening agent tank 312 storing softening agent as automatic processing agent tanks storing laundry processing agents. . The automatic detergent tank 311 and the automatic softener tank 312 are arranged side by side in the width direction of the outer box 11 . According to this, the user can perform the work for the automatic detergent tank 311 and the work for the automatic softener tank 312 at substantially the same position, so that workability can be improved.

The washing machine 10 further includes a water supply valve 17 connected to an external water source and a water supply path 42 . The water supply route 42 is a route from the water supply valve 17 to the water tank 13 via the processing agent manual feeding device 20 and without the processing agent automatic feeding device 30 . Then, the automatic treatment agent injection device 30 introduces the laundry treatment agents stored in the automatic treatment agent tanks 311 and 312 into the water tub 13 via the water supply path 42 .

According to this, the automatic treatment agent injection device 30 introduces the laundry treatment agent stored in the automatic treatment agent tanks 311 and 312 into the water tank 13 using the water supply path 42 for supplying external water. . Therefore, it is not necessary to provide a dedicated path for charging the laundry treatment agent from the automatic treatment agent input device 30 to the water tub 13, or a water supply valve or the like for supplying water to the path. Therefore, according to this embodiment, the configuration for injecting the laundry treatment agent from the automatic treatment agent injection device 30 into the water tank 13 can be made simpler, and the number of parts and cost can be reduced. .

Further, according to the present embodiment, the water supply valve 17 is provided on the same side as the side on which the manual loading device 20 and the automatic loading device 30 are provided with respect to the washing machine 10, as shown in FIG. ing. According to this, the distance from the water supply valve 17 to the manual supply device 20, that is, the distance of the water supply route 42, can be minimized, and furthermore, the distance from the automatic supply device 30 to the water supply route 42 can be minimized. can.

In the first embodiment, the processing agent automatic injection device 30 is connected to the middle portion of the water injection hose 19, but the connection destination of the processing agent automatic injection device 30 may be the middle portion of the water supply path 42. , but not limited to this configuration.

That is, the processing agent automatic injection device 30 may be connected to, for example, the water injection case 21 of the processing agent manual injection device 20, as shown in FIG. In this case, the automatic treatment agent injection device 30 injects the laundry treatment agents stored in the automatic treatment agent tanks 311 and 312 into the water injection case 21 of the treatment agent manual injection device 20 . The laundry treatment agent introduced into the water injection case 21 by the automatic treatment agent injection device 30 is washed away by the water flowing through the water supply path 42 , that is, the water supplied from the water supply valve 17 into the water injection case 21 , and is pushed into the water tank 13 . is put into
This configuration also provides the same effects as those of the first embodiment.

(Second embodiment)
Next, a second embodiment will be described with reference to FIG.
In the first embodiment, the detergent tank 311 for automatic use and the softener tank 312 for automatic use are arranged side by side in the width direction of the outer case 11 . On the other hand, in the present embodiment, the automatic detergent tank 311 and the automatic softener tank 312 are arranged side by side in the depth direction of the outer case 11, that is, in the front-rear direction, as shown in FIG.

In this case, the space in which the automatic detergent tank 311 and the automatic softener tank 312 arranged in front and behind can be arranged becomes larger toward the rear. Therefore, when looking at a configuration in which, for example, the automatic detergent tank 311 is arranged on the front side and the automatic softener tank 312 is arranged on the rear side, the capacity of the automatic softener tank 312 arranged on the rear side is reduced to the front side. By matching the capacity of the arranged automatic detergent tank 311, the automatic detergent tank 311 and the automatic softener tank 312 can have the same shape. That is, by setting the detergent tank 311 for automatic use and the softener tank 312 for automatic use to have the same capacity, parts for the detergent tank 311 for automatic use and the softener tank 312 for automatic use can be shared.
