As shown in FIG. 6, the washing machine 1 includes a first water supply path 51, a second water supply path 52, a conveyance path 53, and an input as a piping path used for cleaning an object to be cleaned (cloth). Path 54.

The first water supply path 51 connects the water supply unit 20 and the first input unit 31 and supplies water from the water supply unit 20 to the first input unit 31. The second water supply path 52 connects the halfway portion of the first water supply path 51 and the conveyance path 53, and supplies water from the water supply unit 20 to the conveyance path 53 through the first water supply path 51. The transport path 53 connects the tank 42 and the first input unit 31 and transports the cleaning treatment liquid discharged from the tank 42 through the transport pump 46. The pour-in path 54 connects the first input portion 31 and the water tank 21 (outer tank 22), and the cleaning treatment liquid and water are input from the first input portion 31 toward the water tank 21.

A switching valve 64 is arranged at a connection between the second water supply path 52 and the conveyance path 53. The switching valve 64 is a switching means for switching the flow of the fluid. The switching valve 64 (switching means) is selectively switched to any one of a direction in which the cleaning treatment liquid flows from the tank 42 to the conveyance path 53 and a direction in which water flows from the second water supply path 52 to the conveyance path 53. .

Further, on the path of the conveyance path 53, a conveyance pump 46 and check valves 47 a and 47 b for preventing the fluid from flowing backward are arranged. The check valves 47 a and 47 b are respectively disposed on the upstream side (the side of the tank 42) and the downstream side (the side of the first input portion 31) of the transfer pump 46.

The washing machine 1 includes a first washing path 61, a second washing path 62, and a discharge path 63 as piping paths used for washing the water tank 21, the outer tank 22, and the casing 41.

The first washing path 61 connects the water supply unit 20 and the first input unit 31 and supplies water for washing from the water supply unit 20 to the first input unit 31. The second washing path 62 connects the halfway part of the first washing path 61 and the case 41, and supplies water for washing from the water supply unit 20 to the case 41 through the first washing path 61. The discharge path 63 connects the case 41 and the drainage port 66 and discharges water from the case 41.

The discharge path 63 includes a drain pipe 63a connecting the case 41 and the air duct 73, a drain pipe 63b connecting the air duct 73 and the outer tank 22, and a drain valve 65 and a drain port 66 provided in the outer tank 22. The drain pipe 63c is connected.

A drain valve 65 is provided in the outer tank 22. The washing machine 1 opens the drain valve 65 and discharges the cleaning treatment liquid and water from the drain port 66 to the outside through the drain pipe 63c.

When such a washing machine 1 is automatically charged (that is, when the cleaning treatment liquid is input into the water tank 21 by the cleaning treatment liquid input device 30), the cleaning treatment liquid stored in the tub 42 is passed through the transport path 53 It is conveyed from the tank 42 to the 1st input part 31. In addition, the washing machine 1 can feed the conveyed cleaning treatment liquid from the first input unit 31 to the water tank 21 through the input path 54. Therefore, since the washing treatment liquid passes through the first input section 31 regardless of whether the washing machine 1 is manually or automatically charged, by passing water through the first input section 31, it is possible to reduce the amount of water used when the lotion is input.

The second water supply path 52 of the washing machine 1 is connected to a part of the first water supply path 51 in the middle. Therefore, the washing machine 1 may assume that the conveying path 53 is blocked, and if an unexpected pressure is applied to the conveying path 53, the pressure applied to the conveying path 53 may be transmitted to the outside through the first water supply path 51 ( Sink 21 side). Therefore, the washing machine 1 can reduce the pressure applied to the conveyance path 53 assuming that this phenomenon occurs. Thereby, the washing machine 1 can maintain the performance of the conveyance path 53 relatively long.

In addition, the washing machine 1 can wash the first input portion 31 by flowing the washing water from the water supply unit 20 toward the first input portion 31 along the first washing path 61.

In addition, the washing machine 1 can wash the case 41 by flowing the water for washing from the water supply unit 20 toward the case 41 along the second washing path 62. In particular, if the nozzle 41a (refer to FIG. 10) fitted to the lower part of the tank 42 is provided at the bottom of the case 41, the nozzle 41a (refer to FIG. 10) may be washed.

Moreover, the washing machine 1 can discharge the water for washing supplied to the first washing path 61 toward the water tank 21 along the input path 54 and the water for washing provided to the second washing path 62 The water tank 21 (through the air duct 73) is discharged toward the water tank 21. Therefore, the washing machine 1 can wash the water tank 21 and the outer tank 22.

<Structure of the tank> Hereinafter, the structure of the tank 42 will be described with reference to FIGS. 7 to 10. 7 to 9 are perspective views each showing an external configuration of the tub 42. FIG. 10 is a cross-sectional view showing the internal structure of the tub 42.

As shown in FIGS. 7 to 9, the tub 42 includes an upper surface cover 43 and a handle portion 44. FIG. 7 shows a state where the insertion port cover 43a is closed. FIG. 8 shows a state where the insertion port cover 43a is opened. FIG. 9 shows a state where the upper surface cover 43 is removed.

The upper surface cover 43 is a cover member that covers the upper surface of the tub 42. The grip handle 44 is a member that is held by a user.

The second input portion 32 is provided on the upper surface cover 43 and is sealed by the input port cover 43a. The entrance opening cover 43a is comprised so that it can be opened and closed in the longitudinal direction from the back.

The upper surface of the upper surface cover 43 is an inclined surface that is inclined downward from the rear toward the front. The upper surface cover 43 can be extended in the opening / closing direction as compared with the case where the upper surface is assumed to be formed in a horizontal plane. In addition, when such an upper cover 43 is opened, the input opening cover 43a can be projected upwardly when the input opening cover 43a is opened. Therefore, such an upper cover 43 can improve the operability of the opening and closing operation of the insertion opening cover 43a, and can easily open and close the insertion opening cover 43a.

As described above, the tank 42 has a structure capable of being detached and attached to the case 41 (refer to FIG. 5) by moving in the vertical direction. The tank 42 can be easily removed from the case 41 by the user pulling the handle portion 44 in the upward direction. As shown in FIG. 9, the upper cover 43 can be removed from the tank 42.

The user can remove the tank 42 from the case 41 and the upper cover 43 from the tank 42, so the case 41 and the upper cover 43 can be easily washed by hand.

As shown in FIG. 10, a discharge port 49 (through-hole) is provided in the lower portion of the tank 42. The discharge port 49 has a structure that fits into a nozzle 41 a provided in the case 41. Accordingly, the tank 42 can reliably send the cleaning treatment liquid toward the transport path 53 (refer to FIG. 6). A bottom surface portion inclined downward toward the discharge port 49 is provided inside the tub 42. In addition, the discharge port 49 is provided with a fine-mesh net-shaped tank net 48. Thus, the washing machine 1 is supposed to prevent foreign matter from entering the conveyance path 53 even if foreign matter enters the inside of the tub 42 (refer to FIG. 6).

<Adding operation of cleaning treatment liquid to the second input portion (automatic input portion)> 的 The washing machine 1 of this embodiment makes it easy to apply the cleaning treatment liquid to the second input portion 32 (automatic input portion, input port) as described below Put into the structure. Here, first, an example of a case where the washing treatment liquid is put into the second loading unit 32 (automatic loading unit) from the washing machine 101 of the comparative example will be described with reference to FIG. 11A. Then, an example of a case where the washing treatment liquid is put into the second loading part 32 (automatic loading part) by the washing machine 1 of this embodiment will be described with reference to FIG. 11B. FIG. 11A is an explanatory diagram showing a state in which the cleaning treatment liquid is put in the washing machine 101 of the comparative example. FIG. 11B is an explanatory diagram showing a state in which the cleaning treatment liquid is put in the washing machine 1 of the present embodiment.

In the washing machine 101 of the comparative example shown in FIG. 11A, like the conventional washing machine, a second input unit 32 is arranged between the water supply unit 20 (water supply means) and the first input unit 31 (manual input unit) (Automatic input unit).

As shown in FIG. 11A, in the washing machine 101 of the comparative example, the second input portion 32 (automatic input portion) is disposed behind the first input portion 31 (manual input portion). In the washing machine 101 of this comparative example, when a user puts the cleaning treatment liquid into the second input portion 32, the housing 11 is in contact with the carcass portion (or bottom) of the replenishing container 91 for the cleaning treatment liquid. Therefore, in the washing machine 101 of the comparative example, it is necessary to arrange the discharge port of the replenishment container 91 at a relatively high position above the second input portion 32, and in this state, input the cleaning treatment liquid to the second input portion 32. In the washing machine 101 of this comparative example, since the cleaning treatment liquid is injected from a relatively high position into the second input portion 32, the cleaning treatment liquid cannot be injected into the second input portion 32 with a high degree of accuracy, and there is a possibility of overflow. As a result, the washing machine 101 of the comparative example has a possibility of contaminating the surroundings of the second input portion 32 with the cleaning treatment liquid.

In this regard, as shown in FIG. 11B, in the washing machine 1 of the present embodiment, the second input portion 32 (automatic input portion) is disposed in front of the first input portion 31 (manual input portion). In the washing machine 1 of this embodiment, when the user puts the cleaning treatment liquid into the second input portion 32, the housing 11 does not come into contact with the body portion (or bottom) of the replenishing container 91 for the cleaning treatment liquid. Therefore, in the washing machine 1 of this embodiment, the discharge port of the replenishment container 91 can be added to the second input portion 32, and the cleaning treatment liquid can be input to the second input portion 32. In the washing machine 1 of this embodiment, the cleaning treatment liquid is injected into the second input portion 32 from a relatively low position. Therefore, the cleaning treatment liquid can be injected into the second input portion 32 without overflowing. As a result, the washing machine 1 of this embodiment can prevent the cleaning treatment liquid from contaminating the periphery of the second input portion 32.

<Arrangement relationship of the insertion opening cover (first cover) and the tank storage cover (second cover)> Hereinafter, the arrangement relationship of the insertion opening cover 43a and the tank storage cover 15 will be described with reference to FIG. 12.

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

(1) A conventional washing machine is provided with a hose connected to a water tank (washing and dewatering tank) in a manual input section and a cleaning treatment liquid input device. That is, the conventional washing machine includes a hose of a first system that connects a manual input unit and a water tank (washing and dewatering tank), and a second system that connects a cleaning processing liquid charging device and a water tank (washing and dewatering tank). System hoses, plural hoses. Since this conventional washing machine has a large number of hoses, it has a relatively high risk of water leakage due to the fall of the hose and the breakage of the hose.

In this regard, as shown in FIG. 6, the washing machine 1 of the present embodiment transfers the cleaning treatment liquid stored in the tub 42 from the tub 42 to the first input portion 31 via the transport path 53 and the input path 54 The water is poured into the water tank 21 from the first loading unit 31.

The washing machine 1 of this embodiment can remove the hose connected to the cleaning processing liquid charging device 30 and the water tank 21. Therefore, compared with the conventional washing machine, the washing machine 1 of the present embodiment can reduce the risk of water leakage caused by the fall of the hose and the breakage of the hose in the portion of the hose that has been cut off. As a result, the washing machine 1 of this embodiment can reduce the risk of water leakage to 1/2 of the conventional washing machine, and can improve the reliability of this part.

(2) The conventional washing machine has a problem that a large amount of water is used when the detergent is supplied because it is necessary to supply water to both the manual input unit and the cleaning treatment liquid charging device when the detergent is input.

In this regard, as shown in FIG. 6, since the water supplied to the washing treatment liquid input device 30 of the washing machine 1 of this embodiment is supplied to the first input portion 31, it is possible to reduce the amount of water used when the detergent is input. The amount of water. As a result, the washing machine 1 of the present embodiment can reduce the amount of water used when the lotion is injected, for example, to about 1/2 of a conventional washing machine, and can reduce the use cost of this part.

(3) In the conventional washing machine, a water supply means is arranged at the upper rear portion of the housing, and a manual input portion is arranged at the front portion thereof. In addition, between the water supply means and the manual input unit, and in a place beside the water tank (washing and dewatering tank), a tank and a input unit (automatic input unit) of the cleaning treatment liquid input device are arranged. Therefore, in the conventional washing machine, a charging section (automatic charging section) of the washing treatment liquid charging device is arranged at a place remote from the position where the user stands. Therefore, the conventional washing machine has a problem that it is difficult for a user to put in the cleaning treatment liquid when the cleaning treatment liquid is put into the automatic loading part, and the usability is poor.

In this regard, as shown in FIG. 5, the washing machine 1 of this embodiment is provided with a second input unit 32 (automatic input unit) at a place close to a position where the user stands. Therefore, the washing machine 1 of this embodiment can easily put the cleaning treatment liquid into the second loading unit 32 (automatic loading unit). Such a washing machine 1 according to this embodiment can improve the usability.

(4) In a conventional washing machine, an automatic charging section of the cleaning treatment liquid charging device is disposed behind the manual charging section. Therefore, in the conventional washing machine, when the user holds the replenishing container for the washing treatment liquid and puts the washing treatment liquid into the automatic charging part, the frame body is in contact with the carcass part (or bottom) of the replenishing container. Therefore, in the conventional washing machine, it is necessary to arrange the discharge port of the replenishment container at a relatively high position above the automatic input section, and to put the cleaning treatment liquid into the automatic input section in this state. Such a conventional washing machine has a problem in that the cleaning treatment liquid is injected into the automatic insertion portion from a relatively high position, and therefore there is a possibility that the cleaning treatment liquid cannot be injected into the automatic insertion portion in a clever manner and there is a possibility of overflow.

In this regard, as shown in FIG. 11B, in the washing machine 1 of the present embodiment, the second input portion 32 (automatic input portion) is disposed in front of the first input portion 31 (manual input portion). Therefore, in the washing machine 1 of this embodiment, when the user holds the replenishing container 91 for the washing treatment liquid and puts the washing treatment liquid into the second loading part 32 (automatic loading part), the housing 11 does not contact the carcass of the replenishing container 91 The bottom (or bottom) is in conflict. Therefore, in the washing machine 1 of this embodiment, the discharge port of the replenishment container 91 can be added to the second input portion 32, and the cleaning treatment liquid can be input to the second input portion 32. In the washing machine 1 of this embodiment, the cleaning treatment liquid is injected into the second input portion 32 from a relatively low position. Therefore, the cleaning treatment liquid can be injected into the second input portion 32 without overflowing. As a result, the washing machine 1 of this embodiment can prevent the cleaning treatment liquid from contaminating the periphery of the second input portion 32.

(5) The conventional washing machine has a problem that when a user puts the cleaning treatment liquid into the automatic insertion part, the cleaning treatment liquid overflows the operation panel, causing the buttons and touch panels to malfunction.

In this regard, as described in the item (4), the washing machine 1 of the present embodiment can put the cleaning treatment liquid into the second input portion 32 (automatic input portion) without overflowing. Therefore, in the washing machine 1 of this embodiment, the cleaning process liquid overflows toward the operation panel 14 (refer to FIG. 1), so that the malfunction of the buttons and the touch panel can be suppressed.

(6) In the automatic charging section of the cleaning processing liquid charging device, a larger amount of cleaning processing liquid is charged than the manual charging section. Even so, in the conventional washing machine, the automatic input section is disposed further rearward than the manual input section. Therefore, a conventional washing machine (especially, an upright washing machine) has a problem that it is inconvenient to use a washing treatment liquid charging device.

In this regard, as shown in FIG. 5, in the washing machine 1 of the present embodiment, a second input section 32 (automatic input section) in which a relatively large amount of cleaning treatment liquid is input is provided in a position larger than the first input section 31 (manual input). Part) more forward. Therefore, the washing machine 1 of this embodiment can improve the usability of the washing treatment liquid charging device 30.

(7) When the conventional washing machine has a drying function, for example, a drying unit is arranged at the upper rear portion of the housing. The conventional washing machine having this structure has a relatively close distance between the tank and the drying unit of the cleaning treatment liquid input device, and therefore has a function of gelling the cleaning treatment liquid stored in the tank by heat from the drying unit. Topic.

In this regard, as shown in FIG. 4, in the washing machine 1 of the present embodiment, a drying unit 71 is disposed on the upper rear portion of the housing 11, and a cleaning treatment liquid charging device 30 is disposed on the upper front portion of the housing 11. That is, in the washing machine 1 of the present embodiment, the cleaning treatment liquid charging device 30 is disposed at a place farthest from the drying unit 71 in the upper portion of the housing 11. Therefore, the washing machine 1 of the present embodiment can suppress gelation of the cleaning treatment liquid stored in the tub 42 due to heat from the drying unit 71.

(8) In general washing machines, it is desirable to reduce the horizontal width. However, in the conventional washing machine, since the washing treatment liquid charging device is installed in a place beside the water tank, it is necessary to reduce the size of the clothes input unit (the opening of the water tank). Thereby, a conventional washing machine (especially, an upright washing machine) has a problem of reducing the ease with which clothes can be put in.

In this regard, as shown in FIG. 5, the washing machine 1 of the present embodiment is equipped with a washing treatment liquid charging device 30 at a place in front of the water tank 21. Therefore, it is not necessary to reduce the size of the laundry input section (the opening of the water tank 21). Therefore, the washing machine 1 of this embodiment can improve the ease of putting in clothes.

(9) The conventional washing machine has a structure in which a tank with a cleaning treatment liquid input device is arranged at a side of the water tank (washing and dewatering tank) so as to extend forward and backward, and the tank cannot be removed. . Therefore, the conventional washing machine has a problem that the tub and the like cannot be washed.

In this regard, as shown in FIGS. 7 to 9, the washing machine 1 of the present embodiment can remove the tub 42 of the cleaning treatment liquid into the device 30, and therefore, the tub 42 and the like can be washed.

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

In this regard, as shown in FIGS. 7 and 8, the washing machine 1 of this embodiment is configured to be openable and closable in a longitudinal direction from the front to the rear lid 43 a (first cover). Therefore, the washing machine 1 of this embodiment can open the insertion opening cover 43a (first cover) regardless of the dominant hand. As a result, the washing machine 1 of this embodiment can easily put (replenish) the cleaning treatment liquid into the second input portion 32 (automatic input portion) regardless of the dominant hand.

(11) The conventional washing machine has a problem that the cleaning treatment liquid leaks out of the tub of the cleaning treatment liquid when the user forgets to perform the cleaning with the lid of the automatic input portion closed.

In this regard, as shown in FIG. 12, the washing machine 1 of this embodiment is assumed to be cleaned even when the user forgets to lock the insertion opening cover 43 a (first cover). 15 (Second cover), the insertion opening cover 43a can be automatically locked. Therefore, even in this 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 input device 30.

(12) In the conventional washing machine, when the cleaning treatment liquid contained in the tub of the cleaning treatment liquid charging device is sent to the water tank by pressurizing the air, there is a portion on the pipe path through which water does not pass through the cleaning treatment liquid. The conventional washing machine has a problem in that it is difficult to wash the part through which water does not pass.

In this regard, as shown in FIG. 6, although the washing treatment liquid of the washing machine 1 of this embodiment is accommodated in the tub 42 of the washing treatment liquid input device 30, the washing treatment liquid is sent toward the transportation path 53, but water also passes through the transportation path 53 on any of the parts. Therefore, the washing machine 1 of this embodiment can reliably clean the conveyance path 53.

As described above, according to the washing machine 1 of this embodiment, the risk of water leakage can be reduced and the amount of water used when the lotion is input can be reduced.
