As shown in FIG. 11A, in the washing machine 101 of the comparative example, the second input unit 32 (automatic input unit) is disposed behind the first input unit 31 (manual input unit). In the washing machine 101 of the comparative example, when the user puts the cleaning treatment liquid into the second input unit 32, the casing 11 collides with the body portion (or the bottom portion) of the replenishing container 91 of the cleaning treatment liquid. Therefore, in the washing machine 101 of the comparative example, it is necessary to arrange the discharge port of the replenishing container 91 at a relatively high position above the second input unit 32, and in this state, the cleaning treatment liquid is supplied to the second input unit 32. In the washing machine 101 of the comparative example, since the cleaning processing liquid is supplied from the relatively high position to the second input unit 32, the cleaning processing liquid cannot be placed in the second input unit 32 in a high-efficiency manner and may overflow. As a result, the washing machine 101 of the comparative example is likely to contaminate the periphery of the second input unit 32 by the cleaning treatment liquid.

As shown in FIG. 11B, in the washing machine 1 of the present embodiment, the second input unit 32 (automatic input unit) is disposed in front of the first input unit 31 (manual input unit). In the washing machine 1 of the present embodiment, when the user puts the cleaning treatment liquid into the second input unit 32, the casing 11 does not interfere with the body portion (or the bottom portion) of the replenishing container 91 of the cleaning treatment liquid. Therefore, in the washing machine 1 of the present embodiment, the discharge port of the replenishing container 91 can be added to the second input unit 32, and the cleaning liquid can be supplied to the second input unit 32. In the washing machine 1 of the present embodiment, since the cleaning processing liquid is supplied from the relatively low position to the second input unit 32, the cleaning processing liquid can be introduced into the second input unit 32 without overflow. As a result, the washing machine 1 of the present embodiment can suppress contamination of the periphery of the second input unit 32 by the cleaning treatment liquid.

<Main Features of Washing Machine> In the present embodiment, since the conventional washing machine has the following problems, the washing machine 1 in consideration of this problem is deliberately provided.

(1) A conventional washing machine is provided with a manual input unit and a cleaning treatment liquid input device, and each has a hose connected to a water tank (washing and dewatering tank). In other words, the conventional washing machine includes a hose of the first system that connects the manual input unit and the water tank (washing and dehydrating tank), and a second system that connects the cleaning treatment liquid to the device and the water tank (cleaning and dehydrating tank). System hose, a plurality of hoses. In such a conventional washing machine, since the number of the hoses is large, there is a problem that the risk of water leakage due to the falling off of the hose and the breakage of the hose is relatively high.

As shown in FIG. 6 , the washing machine 1 of the present embodiment transports the cleaning liquid contained in the tub 42 from the tub 42 to the first input unit 31 through the transport path 53 and passes through the input path 54 . The first input unit 31 is introduced into the water tank 21 .

In the washing machine 1 of the present embodiment, the hose for connecting the cleaning treatment liquid introduction device 30 and the water tank 21 can be removed. Therefore, the washing machine 1 of the present embodiment can reduce the risk of water leakage from the portion of the hose to be removed which is caused by the falling off of the hose and the breakage of the hose, as compared with the conventional washing machine. As a result, the washing machine 1 of the present embodiment can reduce the risk of water leakage to 1/2 of a conventional washing machine, and can improve the reliability of the portion.

(2) In the case of the conventional washing machine, since it is necessary to supply water to both the manual input unit and the cleaning treatment liquid supply device, it is necessary to have a large amount of water used when the lotion is charged.

In the washing machine 1 of the present embodiment, as shown in FIG. 6, the water supplied to the cleaning treatment liquid supply device 30 is supplied to the first input unit 31, so that the use of the lotion can be reduced. The amount of water. As a result, the amount of water used in the washing machine 1 of the present embodiment can be reduced to, for example, 1/2 of the conventional washing machine, and the use cost of the portion can be reduced.

(3) A conventional washing machine has a water supply means disposed at a rear upper portion of the casing, and a manual input portion is disposed in front of the casing. In addition, between the water supply means and the manual input unit, a tank and an input unit (automatic input unit) of the cleaning treatment liquid supply device are disposed in a place on the side of the water tank (cleaning and dewatering tank). Therefore, the conventional washing machine is an input unit (automatic input unit) in which the cleaning treatment liquid input device is disposed at a position away from the position where the user stands. Therefore, in the conventional washing machine, when the user puts the cleaning treatment liquid into the automatic input unit, it is difficult to put the cleaning treatment liquid into it, and the ease of use is poor.

In the washing machine 1 of the present embodiment, the second input unit 32 (automatic input unit) is disposed at a position close to the user's standing. Therefore, in the washing machine 1 of the present embodiment, the cleaning treatment liquid can be easily supplied to the second input unit 32 (automatic input unit). The washing machine 1 of this embodiment can improve the usability.

(4) In the conventional washing machine, the automatic input unit of the cleaning treatment liquid input device is disposed behind the manual input unit. Therefore, in the conventional washing machine, when the user puts the cleaning treatment liquid into the automatic input unit with the replenishing container of the cleaning treatment liquid, the frame body is in contact with the body portion (or the bottom portion) of the refill container. Therefore, in the conventional washing machine, it is necessary to arrange the discharge port of the replenishing container at a relatively high position above the automatic input portion, and in this state, the cleaning treatment liquid automatic input unit is inserted. In the conventional washing machine, since the cleaning processing liquid is supplied to the automatic input unit from a relatively high position, there is a problem that the cleaning processing liquid cannot be put into the automatic input unit in a high-efficiency manner and overflows.

As shown in FIG. 11B, in the washing machine 1 of the present embodiment, the second input unit 32 (automatic input unit) is disposed in front of the first input unit 31 (manual input unit). Therefore, in the washing machine 1 of the present embodiment, when the cleaning container 91 is placed in the second input unit 32 (automatic input unit) by the refill container 91 in which the user holds the cleaning treatment liquid, the housing 11 does not overlap with the cartridge of the refill container 91. The part (or the bottom) is in conflict. Therefore, in the washing machine 1 of the present embodiment, the discharge port of the replenishing container 91 can be added to the second input unit 32, and the cleaning liquid can be supplied to the second input unit 32. In the washing machine 1 of the present embodiment, since the cleaning processing liquid is supplied from the relatively low position to the second input unit 32, the cleaning processing liquid can be introduced into the second input unit 32 without overflow. As a result, the washing machine 1 of the present embodiment can suppress contamination of the periphery of the second input unit 32 by the cleaning treatment liquid.

(5) In the conventional washing machine, when the user puts the cleaning treatment liquid into the automatic input unit, the cleaning treatment liquid overflows the operation panel, causing a malfunction of the button and the touch panel.

In the washing machine 1 of the present embodiment, as described in the above (4), the cleaning processing liquid can be introduced into the second input unit 32 (automatic input unit) without overflow. Therefore, in the washing machine 1 of the present embodiment, by omitting the cleaning processing liquid toward the operation panel 14 (refer to FIG. 1), it is possible to suppress the malfunction of the button and the touch panel.

(6) In the automatic input unit of the cleaning treatment liquid charging device, a larger amount of the cleaning treatment liquid is supplied than the manual input unit. Even in this case, in the conventional washing machine, the automatic input portion is disposed rearward than the manual input portion. Therefore, the conventional washing machine (especially, the upright type washing machine) has a problem that the ease of use of the cleaning treatment liquid input device is poor.

In the washing machine 1 of the present embodiment, the second input unit 32 (automatic input unit) in which a large amount of the cleaning processing liquid is supplied is provided in the first input unit 31 (manual input). Department) is more forward. Therefore, the washing machine 1 of the present embodiment can improve the usability of the cleaning treatment liquid input device 30.

(7) When the conventional washing machine has a drying function, for example, a drying unit is disposed at the upper rear portion of the casing. In the conventional washing machine of this configuration, since the distance between the tub and the drying unit of the cleaning treatment liquid input device is relatively close, the cleaning treatment liquid contained in the tub is gelled by the heat from the drying unit. Question.

In the washing machine 1 of the present embodiment, the drying unit 71 is disposed on the upper rear portion of the casing 11, and the cleaning treatment liquid charging device 30 is disposed on the upper front portion of the casing 11. In other words, in the washing machine 1 of the present embodiment, the cleaning treatment liquid charging device 30 is disposed farthest from the drying unit 71 in the upper portion of the casing 11. Therefore, the washing machine 1 of the present embodiment can suppress the gelation of the cleaning treatment liquid accommodated in the tub 42 by the heat from the drying unit 71.

(8) In general washing machines, it is desirable to reduce the lateral width. However, in the conventional washing machine, since the cleaning treatment liquid introduction device is mounted on the side of the water tank, it is necessary to reduce the size of the laundry input portion (the opening portion of the water tank). Therefore, the conventional washing machine (especially, the upright type washing machine) has a problem that the ease of putting the laundry is lowered.

As shown in FIG. 5, in the washing machine 1 of the present embodiment, the cleaning treatment liquid input device 30 is mounted in a place in front of the water tank 21. Therefore, it is not necessary to reduce the size of the laundry input portion (the opening portion of the water tank 21). Therefore, the washing machine 1 of the present embodiment can improve the ease of putting the laundry.

(9) The conventional washing machine is a tank in which the washing liquid input device is disposed so as to extend in the front-rear direction at a position on the side of the water tank (cleaning and dewatering tank), and the tub can not be removed. . Therefore, the conventional washing machine has a problem that it is impossible to wash the tub or the like.

On the other hand, as shown in FIGS. 7 to 9, the washing machine 1 of the present embodiment can remove the tub 42 and the like, since the tub 42 of the washing treatment liquid can be removed.

(10) A conventional washing machine is provided with a cover that seals the automatic input portion. The cover is a structure that opens to either one of the left and right sides. Such a conventional washing machine has a problem that it is difficult to open the lid when the opening direction of the lid is opposite to the direction of the user's dominant hand.

In the washing machine 1 of the present embodiment, the insertion opening cover 43a (first cover) is configured to be openable and closable in the longitudinal direction from the front to the rear, as shown in Fig. 7 and Fig. 8. Therefore, in the washing machine 1 of the present embodiment, the input port cover 43a (first cover) can be opened regardless of the dominant hand. Thus, the washing machine 1 of the present embodiment can easily (fill) the cleaning treatment liquid to the second input unit 32 (automatic input unit) regardless of the dominant hand.

(11) When the user forgets to close the lid in which the automatic input unit is sealed, the washing machine has a problem that the cleaning treatment liquid leaks from the tank of the cleaning treatment liquid introduction device.

In the washing machine 1 of the present embodiment, the washing machine 1 of the present embodiment is assumed to be cleaned even when the user forgets to lock the insertion flap 43a (first lid). When the 15 (second cover) is closed, the input port cover 43a can be automatically locked. Therefore, even in such a case, the washing machine 1 of the present embodiment can suppress the leakage of the cleaning treatment liquid from the tub 42 of the cleaning treatment liquid charging device 30.

(12) In the conventional washing machine, when the cleaning treatment liquid contained in the tub of the cleaning treatment liquid introduction device is sent to the water tank by air pressure, there is a portion on the piping path through which the water does not pass through the cleaning treatment liquid. The conventional washing machine has a problem of a portion that does not easily pass through the washing water.

As shown in FIG. 6, the washing machine 1 of the present embodiment is sent to the conveyance path 53 while being stored in the tank 42 of the cleaning treatment liquid supply device 30, but the water also passes through the conveyance path. Any of the parts on 53. Therefore, the washing machine 1 of the present embodiment can reliably clean the conveyance path 53.

As described above, according to the washing machine 1 of the present embodiment, it is easy to put the cleaning treatment liquid, and the usability is improved.
