As shown in FIGS. 5 to 7, the main water supply path 14 extends forward substantially horizontally from the outlet of the main water supply valve 16 so as to pass through the left side of the water injection case 12, and When passing, it bends downwards at a substantially right angle, and at its lower end, it bends rightward at a substantially right angle. The lower portion of the front side of the water injection case 12 extends to the right, is bent at a right angle at its right end portion and extends upward, and is connected to the water injection port 23. The ascending portion of the main water supply passage 14 that is connected to the water injection port 23 has a smaller cross-sectional area than the other portions, and is configured so that the water supply rises to the water injection port 23 due to water pressure.

As a result, when the main water supply valve 16 is opened, the tap water supplied from the connection port 19 flows into the main water supply path 14 and flows forward as shown by the thick arrow in FIGS. After that, it flows downward, further flows to the right in the lower part of the front part of the water injection case 12, and is supplied into the manual detergent accommodating portion 13a from the ascended rear water injection port 23. The water supplied to the manual detergent container 13a flows into the lower water injection case 12 as it is, or when the detergent is stored in the manual detergent container 13a, the detergent is melted and flows into the water injection case 12 below. It is supplied from 12 through the water supply duct 15 into the water tank 6.

At this time, as shown in FIGS. 5 and 6, the central portion of the main water supply path 14 that extends from left to right on the lower front side of the water injection case 12 is the detergent supply unit 25 of the automatic detergent feeder 11. It is said that. Therefore, the detergent supply unit 25 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 thereof. As will be described later, the detergent automatic supply device 11 automatically supplies a required amount of detergent or softener to the detergent supply unit 25.

Further, as shown in FIG. 5, the water supply passage 20 for the softener extends forward from the outlet of the water supply valve 17 for the softener, and then rises to be connected to the water inlet 24 for the softener. As a result, when the softener water supply valve 17 is opened, the tap water supplied from the connection port 19 passes through the softener water supply path 20 and the softener as shown by the white arrow in FIG. It is supplied from the water injection port 24 to the manual softener accommodating portion 13b. The water supplied to the manual softener accommodating portion 13b flows into the lower water injection case 12 while melting the accommodated softener, and is supplied from the water injection case 12 through the water supply duct 15 into the water tank 6. ..

In this embodiment, as shown in FIG. 7, the height position A of the water injection port 23, the height position B of the outlet of the main water supply valve 16, and the height of the lower part of the main water supply path 14 (detergent supply unit 25). As for the relationship with the position C, the height position A is the highest, and the height position B and the height position C are in this order. Further, in the present embodiment, the drainage path 26 is provided at the lowest portion of the main water supply path 14. As shown in FIGS. 6 and 7, the water drainage path 26 is provided as, for example, a narrow pipe line that connects the left end bottom portion of the main water supply path 14 and the lower part of the water injection case 12, whereby the main water supply valve 16 is closed. The main water supply path 14 is configured so that water does not collect.

As shown in FIGS. 2 to 4, the detergent automatic charging device 11 includes a drawer-type tank case 27 that is provided so as to be able to be taken in and out from the front side of the main body 1, and a pump 28 that is arranged at a rear portion thereof. Equipped with. The tank case 27 is in the shape of a rectangular box that is long in the front and back with the upper surface open, and is supported by the upper left portion of the main body 1 so as to be slidable in the front and 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 an opening at the upper left portion of the front surface in the main body 1 and a withdrawal position (see FIG. 2) pulled forward from the storage position. It is possible to take it in and out in between.

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

Although not shown in detail, the pump 28 has two sets of suction port and discharge port 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 the liquid and a discharge port 28a for discharging the 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 softening agent tank 31 side, and is configured to pump up the softening agent by rotating the motor in the other direction and discharge the softening agent from the other discharging port 28a. The two discharge ports 28a of the pump 28 are disposed on the left and right above the detergent supply unit 25 of the main water supply path 14, as shown in FIGS. Further, the discharge time of the detergent or the softening agent, that is, the supply amount to the detergent supply unit 25 is controlled by the driving time of the pump 28.

Thus, the detergent automatic dosing device 11 can supply the required amount of the detergent contained in the detergent tank 30 to the detergent supply unit 25 by driving the pump 28, and the interior of the softener tank 31. It is possible to supply the required amount of the softening agent contained in the detergent supply unit 25. Since the discharge port 28a of the pump 28 is connected to the main water supply path 14, the detergent supply path can be shortened as a whole, and the detergent can be prevented from sticking to 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 in a state where the detergent or the softener is supplied to the detergent supply unit 25, the water is supplied to the detergent supply unit 25 by the detergent. Or it flows while melting the softener. Since the discharge port 28a can be washed away by supplying water, it is possible to prevent the detergent from sticking to the discharge port 28a. Then, the detergent or the softening agent is supplied from the water injection port 23 to the manual detergent accommodating portion 13a together with the water supply, and further supplied from the water injection case 12 through the water supply duct 15 into the water tank 6.

Although not shown, in the main body 1, for example, a control device which mainly includes a microcomputer and controls the entire washing machine is provided. The control device controls the water supply valves 16, 17, 18 of the water supply valve unit 10 on the basis of input signals from the sensors and a control program stored in advance in accordance with a driving course set by the user on the operation panel 5. It controls the pump 28, the drum motor, the drain valve, the drying mechanism, etc. of the automatic detergent feeder 11. With this, the washing operation including the washing step, the rinsing step, and the dehydration step and the drying operation are automatically executed. Since the details of each of the washing operation and the drying operation are well known, the description thereof is omitted here.

In the present embodiment, when executing the washing operation, the user automatically puts the detergent and the softening agent by the detergent automatic charging device 11, or manually uses the manual storage case 13 to manually wash the detergent and the softening agent once. It is possible to selectively operate on the operation panel 5 whether or not to add the agent. When the user selects manual loading, the user opens the lid 22 and stores a required amount of detergent (powdered detergent) in the manual detergent accommodating portion 13a of the manual accommodating case 13 at the start of the washing operation. I'll do it. When a softening agent is used, a required amount of the softening agent is placed in the manual softening agent accommodating portion 13b in addition to the above.

When the automatic feeding of the detergent and the softening agent is selected, the control device supplies the required amount of detergent to the detergent feeding unit 25 by the automatic detergent feeding device 11 before starting the water supply in the washing process, and thereafter, The water supply valve 16 is turned on to execute water supply. Further, for the final purpose, before the rinsing step, a required amount of the softening agent is supplied to the detergent supply unit 25 by the automatic detergent supply device 11, and then the main water supply valve 16 is opened to supply water. On the other hand, when the manual introduction of the detergent and the softener is selected, the main water supply valve 16 performs the water supply in the washing process without operating the automatic detergent supply device 11. Then, at the time of water supply in the rinsing stroke for the last, water is supplied by opening the softener water supply valve 17 instead of the main water supply valve 16.

Next, the operation and effect of the washing machine having the above structure will be described. As a preparation for using the automatic detergent introducing device 11, the user stores the detergent in the detergent tank 30 and the softener in the softener tank 31. The operations of accommodating and replenishing the detergent and the softening agent in the tanks 30 and 31 can be performed as follows. That is, the user puts his/her finger on the handgrip 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. When the tank case 27 is pulled out, the detergent tank 30 or the softening agent tank 31 is taken out upward to replenish the tanks 30 and 31 with the detergent and the softening agent. After the refilling work, the tanks 30 and 31 are returned to the tank case 27, and the tank case 27 is pushed back to the storage position. A structure is provided in which 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 taking out the tanks 30 and 31) to replenish the detergent and the softening agent. You can also do it.

When executing the washing operation in the washing machine, the user operates the power switch 4 to turn on the power and stores the clothes in the drum. At the same time, a driving course is selected by the operation panel 5. At this time, when the manual introduction of the detergent and the softening agent is selected, the user opens the lid 22 on the upper surface of the main body 1, stores the required amount of detergent in the manual detergent storage portion 13a of the manual storage case 13, A required amount of the softening agent is put into the manual softening agent storage portion 13b, and the washing operation is started. When the automatic introduction of the detergent and the softening agent 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 well-known washing, rinsing, and dehydrating steps. At this time, in the washing step, first, water is supplied to the water tank 6 up to a predetermined water level. However, if automatic detergent injection is selected, the automatic detergent injection device 11 is started before starting 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 arrow in FIGS. 5 to 7, water from the water supply source (tap water) flows through the main water supply path 14, passes through the detergent supply section 25, and then rises. Then, it 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 is melted and flows, and the detergent is contained in the water tank 6 from the manual detergent storage unit 13a through the water injection case 12 and the water supply duct 15 in order. The washing water is supplied and the washing process is executed.

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

After this, the process proceeds, and before the water supply in the rinsing process for the last time, if automatic detergent injection is selected, the pump 28 of the automatic detergent injection device 11 is driven, and this time the detergent supply unit 25. Is supplied with the required amount of softener. After this, the main water supply valve 16 is opened, and the water flowing through the main water supply passage 14 flows while melting the softening agent in the detergent supply section 25 and rises to rise from the water injection port 23 to the manual detergent storage case of the manual storage case 13. It is poured into the portion 13a. The washing water containing the softening agent is supplied to the water tank 6 through the water injection case 12 and the water supply duct 15 in order, and the rinse process is executed for the last time.

On the other hand, when the manual feeding is selected, the last rinsing stroke water supply is performed by opening the softener water supply valve 17 instead of the main water supply valve 16. When the water valve 17 for the softening agent is opened, water flows through the water supply path 20 for the softening agent and is poured into the manual softening agent accommodating portion 13b from the water inlet 24 for the softening agent, as shown by an outline arrow in FIG. .. Then, the softening agent previously stored in the manual softening agent storage portion 13b flows into the water injection case 12 while being melted, and the wash water containing the softening agent is supplied into the water tank 6 through the water supply duct 15. The rinse process is executed for the last time.

Here, in the present embodiment, in the water supply mechanism 7, the water supply valve unit 10 (main water supply valve 16) is provided in the rear part of the main body 1, and the automatic detergent introducing device 11 is provided in the front part of the main body 1, A manual storage case 13 is provided between them. Since the automatic detergent introducing device 11 is provided on the front side of the upper portion of the main body 1, the user can easily take out the detergent tank 30 and the softening agent tank 31 as compared with the case where they are arranged at the rear portion. It is possible to easily perform the work of replenishing the detergent and softening agent with respect to 31. In particular, when the tanks 30 and 31 are taken out and the detergent and the softening agent are replenished, the tanks 30 and 31 may become heavy, but since the tanks 30 and 31 are on the front side, the mounting is 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. Along with this, the main water supply valve 16 of the water supply valve unit 10 is also connected to the detergent. The position of the automatic feeding device 11 up to the detergent supply unit 25 can be relatively close, that is, slightly before the manual storage case 13, so that the length of the water supply path therebetween can be shortened. Therefore, the length of the main water supply path 14 can be relatively short as a whole. Further, the length of the water supply path 20 for the softening agent can be shortened.

As a result, according to the present embodiment, the automatic detergent feeding device 11 is provided, and the workability for replenishing the tanks 30 and 31 with the detergent and the softening agent can be improved, and moreover, It is possible to obtain an excellent effect that the water supply paths 14 and 20 can be 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 automatic detergent dosing device 11, whereby the water supply path is provided at the side portion (surrounding in front view) of the automatic detergent dosing device 11. It is not necessary to provide it. Therefore, the automatic detergent injection device 11 can be arranged compactly, in other words, the capacity of the detergent tank 30 and the softening agent tank 31 can be increased.

In particular, in the present embodiment, the detergent supply unit 25 of the automatic detergent feeding 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 thereof. As a result, the main water supply path 14 can be shared by the automatic detergent feeding device 11 and the manual detergent container 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, the configuration can be greatly simplified and the control can be simplified, and the cost can be reduced.

In addition, even when the manual detergent accommodating portion 13a is used, the water supply passes through the detergent supplying portion 25, and also when the automatic detergent introducing device 11 is used, the water supply passes through the manual detergent accommodating portion 13a. Like Thus, the detergent supply section 25 and the manual detergent accommodating section 13a can be washed at every water supply.

In the present embodiment, the detergent supply unit 25 of the automatic detergent dosing device 11 is located at a position lower than the height of the main water supply valve 16, and the main water supply passage 14 rises downstream of the detergent supply unit 25 to store the manual detergent. It is configured to inject water from the water inlet 25 above the portion 13a. As a result, the detergent supply part 25 of the main water supply path 14 is located at a position lower than the position of the outlet of the main water supply valve 16, so that backflow of water to the main water supply valve 16 can be prevented. Further, since the main water supply path 14 is configured to rise downstream of the detergent supply unit 25 and pour water from above the manual detergent container 13a, water is vigorously supplied from above in the manual detergent container 13a. It is possible to pour, and it becomes possible to effectively flow the powder detergent in the manual detergent container 13a, that is, to make it flow out without remaining.

Further, in the present embodiment, the lowest portion of the main water supply passage 14 is provided with the water drainage passage 26 for draining water when the main water supply valve 16 is stopped. When the main water supply valve 15 is stopped, water may be accumulated from the outlet of the main water supply valve 16 to the detergent supply unit 25 portion of the main water supply passage 14. However, since the water drainage passage 26 is provided, water is accumulated in that portion. It is possible to prevent water from remaining accumulated. By preventing the water from being accumulated, it is possible to prevent the water from being frozen in the water supply path.
