As shown in FIGS. 2 to 4, the detergent automatic charging device 11 includes a drawer-type tank case 27 provided so as to be able to be taken in and out from the front side with respect to the main body 1, and a pump 28 arranged in the rear portion. Is equipped with. The tank case 27 has a long rectangular box shape in the front-rear direction when the upper surface is open, and is supported by the upper left portion in the main body 1 so as to be slidable in the front-rear direction. A front door 29 having a handle portion 29a is provided on the front surface of the tank case 27. The tank case 27 has a storage position (see FIG. 1 and the like) in which the front door 29 closes the opening in the upper left portion of the front surface of the main body 1 and a drawer position (see FIG. 2) pulled forward from the storage position. It is said that it can be taken in and out between.

In the tank case 27, a detergent tank 30 and a softener tank 31 are provided side by side so as to be removable. Although not shown in detail, both the detergent tank 30 and the softener tank 31 have an elongated tank shape in the front-rear direction, and are configured so that the user can open the lid to replenish the detergent and the softener. In this case, the detergent tank 30 contains a liquid detergent that can be used for a plurality of washings, and the fabric softener tank 31 contains a softening agent that can be used for a plurality of washings.

Although not shown in detail, the pump 28 has two sets of suction ports and discharge ports 28a (see FIG. 6), and is configured with a motor as a drive source. The pump 28 is configured to switch between a suction port for sucking liquid and a discharge port 28a for discharging liquid by switching the rotation direction (energization direction) of the motor. At this time, one suction port is connected to the detergent tank 30 side, and the detergent is pumped up by one-way rotation of the motor and discharged from the one discharge port 28a. The other suction port is connected to the softener tank 31 side, and the softener is pumped up by rotation in the other direction of the motor and discharged from the other discharge port 28a. As shown in FIGS. 5 to 7, the two discharge ports 28a of the pump 28 are arranged on the left and right above the detergent supply unit 25 of the main water supply path 14. Further, the discharge amount of the detergent or the softener, that is, the supply amount to the detergent supply unit 25 is controlled by the driving time of the pump 28.

With this, the detergent automatic charging device 11 can supply the detergent contained in the detergent tank 30 to the detergent supply unit 25 in a required amount by driving the pump 28, and also in the softener tank 31. The softener contained in the detergent can be supplied to the detergent supply unit 25 in a required amount. Since the discharge port 28a of the pump 28 is connected to the main water supply path 14, the detergent supply path is shortened as a whole, and the detergent can be prevented from sticking in the supply path. At this time, when the main water supply valve 16 is turned on and water is supplied to the main water supply path 14 while the detergent or the softener is supplied to the detergent supply unit 25, the water is detergent in the detergent supply unit 25. Alternatively, it flows while melting the softener. Since the discharge port 28a can be washed away by the water supply, it is possible to prevent the detergent from sticking to the discharge port 28a portion. Then, the detergent or the softener is supplied to the manual detergent accommodating portion 13a from the water injection port 23 together with the water supply, and further supplied from the water injection case 12 to the water tank 6 through the water supply duct 15.

Although not shown, a control device which is mainly composed of a microcomputer, for example, and controls the entire washing machine is provided in the main body 1. The control device has the water supply valves 16, 17, and 18 of the water supply valve unit 10 based on the input signals from the sensors and the control program stored in advance according to the operation course set by the user on the operation panel 5. , The pump 28 of the detergent automatic charging device 11, the drum motor, the drain valve, the drying mechanism, and the like are controlled. With this, the washing operation consisting of the washing process, the rinsing process, and the dehydrating process and the drying operation are automatically executed. Since the details of each process of the washing operation and the drying operation are well known, the description thereof will be omitted here.

In the present embodiment, when the user executes the washing operation, the detergent and the softener are automatically added by the detergent automatic addition device 11, or the detergent and the softener for one time are manually added by using the manual storage case 13. It is possible to select and operate on the operation panel 5 whether to add the agent. When the user selects manual charging, the lid 22 is opened in advance at the start of the washing operation, and the required amount of detergent (powder detergent) is stored in the manual detergent storage unit 13a of the manual storage case 13. I'll do it. When a softener is used, a required amount of the softener is charged into the manual softener accommodating portion 13b in addition to the above.

When the automatic addition of detergent and softener is selected, the control device supplies the required amount of detergent to the detergent supply unit 25 by the automatic detergent addition device 11 before the start of water supply in the washing process, and then the main. The water supply valve 16 is turned on to supply water. Further, before the final rinsing process, the required amount of the softener is supplied to the detergent supply unit 25 by the detergent automatic charging device 11, and then the main water supply valve 16 is opened to supply water. On the other hand, when the manual addition of the detergent and the softener is selected, the water supply in the washing process is executed by the main water supply valve 16 without operating the detergent automatic addition device 11. Then, at the time of water supply in the final rinsing process, the water supply valve 17 for the softener is opened instead of the main water supply valve 16 to supply water.

Next, the operation and effect of the washing machine having the above configuration will be described. In preparation for using the detergent automatic charging device 11, the user stores the detergent in the detergent tank 30 and stores the softener in the softener tank 31. The operations of storing and replenishing the detergent and the softener in the tanks 30 and 31 can be performed as follows. That is, the user puts his / her finger on the handle portion 29a of the front door 29 on the front surface of the main body 1 and pulls out the tank case 27 in the storage position toward the front. At the drawer position of the tank case 27, the detergent tank 30 or the softener tank 31 is taken out upward, and the detergent and the softener are replenished to the tanks 30 and 31. After the replenishment work, the tanks 30 and 31 are returned to the tank case 27, and the tank case 27 is pushed in to return to the storage position. A lid is provided on the upper surface of each of the tanks 30 and 31, and the tank case 27 is pulled out and the lid is opened (without removing the tanks 30 and 31) to replenish the detergent and the softener. You can also do it.

In executing the washing operation in the washing machine, the user operates the power switch 4 to turn on the power and store the clothes in the drum. At the same time, the driving course is selected by the operation panel 5. At this time, when the manual addition of the detergent and the softener is selected, the user opens the lid 22 on the upper surface of the main body 1 and stores the required amount of detergent in the manual detergent accommodating portion 13a of the manual accommodating case 13. A required amount of softener is charged into the manual softener accommodating portion 13b, and the washing operation is started. If the automatic addition of detergent and softener is selected, the washing operation can be started as it is.

When the washing operation is started, the control device controls each mechanism of the washing machine and automatically executes the washing operation including the well-known washing, rinsing, and dehydrating processes. At this time, in the washing process, water is first supplied to the water tank 6 up to a predetermined water level, but if automatic detergent charging is selected, the detergent automatic charging device 11 is used before the start of water supply. By controlling the pump 28, a required amount of detergent is supplied to the detergent supply unit 25. In the water supply operation, the main water supply valve 16 is opened.

When the main water supply valve 16 is opened, as shown by the thick arrows in FIGS. 5 to 7, water from the water supply source (water supply) flows through the main water supply path 14, passes through the detergent supply section 25, and then rises. Then, the water is poured from the water injection port 23 into the manual detergent accommodating portion 13a of the manual accommodating case 13. When the detergent is automatically supplied to the detergent supply unit 25, the detergent flows while being melted, passes through the water injection case 12 and the water supply duct 15 in order from the manual detergent storage unit 13a, and contains the detergent in the water tank 6. However, the washing water is supplied and the washing process is executed.

On the other hand, when the manual injection of the detergent is selected, the detergent does not exist in the detergent supply unit 25, so that the water flowing through the main water supply path 14 passes through the detergent supply unit 25 as it is and is manually injected from the water injection port 23. It is poured into the detergent accommodating portion 13a. Then, the detergent stored in the manual detergent accommodating portion 13a is melted and flows into the water injection case 12, the washing water containing the detergent is supplied into the water tank 6 through the water supply duct 15, and the washing process is executed. NS.

After that, when the process progresses and before the water supply in the rinsing process for the last time, the pump 28 of the detergent automatic charging device 11 is driven when the automatic detergent charging is selected, and this time, the detergent supply unit 25 is driven. The required amount of softener is supplied. After that, the main water supply valve 16 is opened, and the water flowing through the main water supply path 14 flows while melting the softener in the detergent supply section 25, rises, and stores the manual detergent in the manual storage case 13 from the water injection port 23. It is poured into the portion 13a. The washing water containing the soft finishing agent is supplied into the water tank 6 through the water injection case 12 and the water supply duct 15 in order, and the final rinsing process is executed.

On the other hand, when manual charging is selected, the water supply in the final rinsing process is performed by opening the water supply valve 17 for the softener instead of the main water supply valve 16. By opening the water supply valve 17 for the softener, water flows through the water supply path 20 for the softener and is poured into the manual softener accommodating portion 13b from the water injection port 24 for the softener, as shown by the white arrow in FIG. .. Then, the softener previously stored in the manual softener accommodating portion 13b is melted and flows into the water injection case 12, and the washing water containing the softener is supplied into the water tank 6 through the water supply duct 15. The rinse process is performed for the last time.

Here, in the present embodiment, of the water supply mechanism 7, the water supply valve unit 10 (main water supply valve 16) is provided at the rear portion of the main body 1, and the detergent automatic charging device 11 is provided at the front portion of the main body 1. A storage case 13 for manual operation is provided between them. Since the detergent automatic charging device 11 is provided on the front side of the upper part of the main body 1, the user can easily take out the detergent tank 30 and the softener tank 31 as compared with the case where the detergent tank 30 and the softener tank 31 are arranged at the rear part. The detergent and softener replenishment work for 31 can be easily performed. In particular, when the tanks 30 and 31 are taken out and replenished with detergent and a softener, the tanks 30 and 31 may become heavy, but since the tanks 30 and 31 are on the front side, the mounting becomes relatively easy.

Since the water supply valve unit 10 is close to the manual detergent storage portion 13a of the manual storage case 13, the length of the water supply path between them is relatively short, and at the same time, the detergent is supplied from the main water supply valve 16 of the water supply valve unit 10. Since the position of the automatic charging device 11 to the detergent supply unit 25 can be relatively close, that is, slightly in front of the manual storage case 13, the length of the water supply path between them can be shortened. Therefore, the length of the main water supply path 14 can be made relatively short as a whole. Further, the length of the water supply path 20 for the softener can be shortened.

As a result, according to the present embodiment, in the device provided with the detergent automatic charging device 11, the workability for replenishing the detergent and the softener into the tanks 30 and 31 can be improved, and moreover, the workability can be improved. It is possible to obtain an excellent effect that the water supply routes 14 and 20 can be made relatively short as a whole. At this time, in the present embodiment, the detergent supply unit 25 is arranged on the rear end side of the detergent automatic charging device 11, whereby the water supply path is provided on the side portion (periphery in front view) of the detergent automatic charging device 11. It does not have to be provided. Therefore, the detergent automatic charging device 11 can be arranged compactly, in other words, the capacities of the detergent tank 30 and the softener tank 31 can be increased.

In particular, in the present embodiment, the detergent supply unit 25 of the automatic detergent charging device 11 is provided on the upstream side of the main water supply path 14, and the manual detergent storage unit 13a is provided on the downstream side of the main water supply path 14. As a result, the main water supply path 14 can be shared with the detergent automatic charging device 11 and the manual detergent accommodating portion 13a, and the main water supply valve 16 can also be shared to provide a mechanism for switching the water supply path. It can be unnecessary. Therefore, it is possible to greatly simplify the configuration and control, and it is possible to reduce the cost.

Further, even when the manual detergent storage unit 13a is used, the water supply passes through the detergent supply unit 25, and at the same time, even when the detergent automatic charging device 11 is used, the water supply passes through the manual detergent storage unit 13a. It will be like. As a result, the detergent supply unit 25 and the manual detergent storage unit 13a can be cleaned at each water supply.

In the present embodiment, the detergent supply unit 25 of the automatic detergent charging device 11 is located at a position lower than the height of the main water supply valve 16, and the main water supply path 14 rises downstream of the detergent supply unit 25 to accommodate the manual detergent. It is configured to inject water from the water injection port 23 above the portion 13a. As a result, since the detergent supply section 25 portion of the main water supply path 14 is located at a position lower than the position of the outlet portion of the main water supply valve 16, it is possible to prevent backflow of water to the main water supply valve 16. Further, since the main water supply path 14 is configured to rise downstream of the detergent supply unit 25 and inject water from above the manual detergent storage unit 13a, the manual detergent storage unit 13a vigorously injects water from above. It can be poured, and the powder detergent in the manual detergent accommodating portion 13a can be effectively flushed, that is, it can be drained without leaving any residue.

Further, in the present embodiment, the lowest portion of the main water supply path 14 is provided with a drainage path 26 for draining water when the main water supply valve 16 is stopped. When the main water supply valve 16 is stopped, it is conceivable that water collects from the outlet portion of the main water supply valve 16 to the detergent supply portion 25 of the main water supply path 14, but by providing the drainage path 26, it is possible that water collects in that portion. It is possible to prevent water from remaining in the pool. By preventing the water from remaining accumulated, it is possible to prevent the water from freezing in the water supply path.
