Fig. 1 is a longitudinal sectional view of a drum washing machine in the first embodiment. Fig. 2 is an exploded perspective view of a liquid container group of the drum washing machine in the first embodiment. Fig. 3 is a perspective view of a liquid container group of the drum washing machine in the first embodiment. Fig. 4 is an exploded perspective view of a storage portion of the drum washing machine in the first embodiment. Fig. 5A is a perspective view of a water filling cap of the drum washing machine in the first embodiment as viewed from the back. Fig. 5B is an enlarged view of part A of Fig. 5A. In addition, in Fig. 4, a cover plate 43 described later is omitted.

As shown in FIG. 1 , a water tank 103 elastically supported by a vibration-proof device (not shown) is provided inside a housing 102 constituting the outer shell of the drum-type washing machine in the present embodiment, and a rotating drum 104 for accommodating laundry and rotating freely is contained inside the water tank 103.

A detergent supply cylinder 2 is disposed on the upper portion of the housing 102. The detergent supply cylinder 2 includes: a liquid container group 22 for accommodating detergent; a water supply path 131 connected to the water supply valve 107 and supplying water to the liquid container group 22; and a receiving portion 21 for storing the liquid container 23 constituting the liquid container group 22 so that it can be pulled out from the front. The detergent supply cylinder 2 is formed so that the front-rear direction of the housing 102 is the long side direction.

The accommodating portion 21 is combined with a water filling cover 25 at the upper portion. An accommodating space 24 is formed between the lower portion of the water filling cover 25 and the frame 44 (see FIG. 4 ), and a liquid container set 22 is freely accommodated in the accommodating space 24. In addition, the liquid container set 22 is configured such that it cannot be pulled out beyond the accommodating portion 21 to allow the detergent to be placed in the liquid chamber 29 (see FIG. 8 ). This is because if it is configured such that it can be pulled out further, it will fall off the accommodating portion 21, causing inconvenience to the user.

A discharge port 26 is provided at the front lower portion of the accommodating portion 21 for discharging the detergent filled in the liquid container set 22. The discharge port 26 is connected to the water tank 103 through the detergent liquid supply path 141 and the water tank water supply path 126. The detergent is supplied to the water tank 103 through the discharge port 26, the detergent liquid supply path 141, and the water tank water supply path 126 together with the supplied water.

The liquid container set 22 is composed of a liquid container 23 and a liquid container cover 31. The liquid container cover 31 is provided to cover the upper part of the liquid container 23. The liquid container 23 is provided with: a liquid chamber 29, which can be charged with a liquid for one washing operation; and a tank 50, which stores a plurality of liquids. The liquid contained in the tank 50 is charged into the water tank 103 by an automatic liquid charging device (not shown).

The liquid container cover 31 is provided with an opening portion 35 formed to face the liquid chamber 29 and a groove cover 51 that covers the groove 50 in an openable and closable manner.

Two rows of first ribs 32 are vertically arranged on the upper surface of the liquid container cover 31 in the longitudinal direction, and the two rows of first ribs 32 are formed on the sides of the inner recessed portion 34 which is a recessed portion provided behind the opening portion 35 .

On the upper surface of the liquid container cover 31 , a plurality of third ribs 33 are vertically provided on both outer side surfaces of the two rows of first ribs 32 , namely, outer side portions 36 , in a direction substantially perpendicular to the first ribs 32 .

The accommodating portion 21 is composed of the following components: a connection port 27a and a connection port 28a connected to the water supply path 131 of the water supply valve 107, a frame 44 formed in a substantially U shape, connection ports 27b and 28b connected and communicated with the connection ports 27a and 28a, and a water injection cover 25. The water injection cover 25 has a cover cover plate 43 (omitted in FIG. 4, refer to FIG. 6 and FIG. 7) joined in one piece, and the space formed by the joining becomes a water passage from the water supply path 131.

On the back side of the water injection cover 25, i.e., the lower surface of the water injection cover 25, there are a plurality of water injection holes 41 formed in two rows in the longitudinal direction. Around the water injection holes 41, a second rib 42 is vertically arranged to surround the water injection holes 41 on three sides. The side surfaces of the second rib 42 are formed to be inclined. In addition, the water injection part is formed by the water injection holes 41 and the second rib 42. However, the water injection part in the present disclosure is not limited to the structure including ribs (the second rib 42 in the present embodiment) that guide water passing through the water injection holes (the water injection holes 41 in the present embodiment).

Fig. 6 is a cross-sectional view of the drum-type washing machine in the first embodiment, showing a state where the liquid container set is stored in the storage portion. Fig. 7 is a cross-sectional view taken along line 7-7 of Fig. 6 .

As shown in Fig. 6 and Fig. 7, when the liquid container set 22 is stored in the accommodating portion 21, the plurality of water injection holes 41 of the water injection cover body 25 are arranged above the opening portion 35. Thus, the water injected from the water injection holes 41 passes through the opening portion 35 of the liquid container cover 31 and is smoothly injected into the liquid chamber 29. In addition, the second rib 42 constituting the water injection portion together with the water injection holes 41 guides the water to the center of the opening portion 35 by means of the inclined lateral surface.

The water injection holes 41 are arranged in two rows with the open surfaces of the second ribs 42 facing each other. The first ribs 32 formed on the liquid container cover 31 are located outside the second ribs 42, and the upper ends of the first ribs 32 are located above the lower ends of the second ribs 42.

The following describes the operation of the drum washing machine constructed as above. (Water injection operation)

Fig. 8 is a cross-sectional view of the drum-type washing machine in the first embodiment in a state where the liquid container set has been pulled out from the accommodating portion. Fig. 9A is a cross-sectional view taken along line 9A-9A of Fig. 8. Fig. 9B is an enlarged view of the B portion of Fig. 9A. Fig. 10A is a cross-sectional view of the third rib in a state where the liquid container set of the drum-type washing machine in the first embodiment has been pulled out from the accommodating portion. Fig. 10B is an enlarged view of the C portion of Fig. 10A.

When the water injection operation is performed, the water injected from the water injection through hole 41 is guided by the second ribs 42 surrounding the water injection through hole 41 on three sides and falls toward the opening 35 .

When the operation starts in a state where the liquid container set 22 is pulled out from the accommodating portion 21 , the plurality of water injection through holes 41 of the water injection cover body 25 are located behind the opening 35 of the liquid container cover 31 of the liquid container set 22 .

When water is poured into the liquid container assembly 22 after it has been pulled out of the accommodating portion 21, the poured water is guided by the second rib 42 and falls into the inner concave portion 34. The second rib 42 restricts the direction of the water so that the water does not scatter around the inner concave portion 34. In addition, in the state where the liquid container assembly 22 has been pulled out of the accommodating portion 21, the first rib 32 is arranged to cover the lower side of the second rib 42. That is, the first rib 32 formed on the liquid container cover 31 is located on the outer side of the second rib 42, and the upper end of the first rib 32 is located higher than the lower end of the second rib 42. Therefore, the two first ribs 32 provided vertically in the longitudinal direction of the liquid container cover 31 can prevent the water falling into the inner recess 34 from flowing out to the side over the first rib 32. The water falling into the inner recess 34 between the first ribs 32 flows down toward the liquid chamber 29 of the liquid container 23 through the opening 35.

In addition, even when the water injected from the water injection through hole 41 flows out to the outer side portion 36 further outward than the first rib 32, it is stopped by the plurality of third ribs 33 vertically arranged in a direction substantially perpendicular to the first rib 32. The stopped water is guided to the left and right sides by the third ribs 33 and flows from the accommodating space 24 of the accommodating portion 21 toward the discharge port 26. (Function, etc.)

As described above, the drum-type washing machine in this embodiment includes: a liquid container 23, which is accommodated in the accommodating portion 21 so as to be taken out and put in; a liquid container cover 31, which covers the upper surface of the liquid container 23; and a water injection through hole 41, which injects water into the liquid container 23 from above. The liquid container cover 31 includes: an opening portion 35, which is located below the water injection through hole 41 when the liquid container 23 is accommodated in the accommodating portion 21; and a first rib 32 formed on the upper surface of the liquid container cover 31. The first rib 32 is provided to cover the side of the water injection through hole 41 when the liquid container 23 is pulled out from the accommodating portion 21.

Thus, when the liquid container 23 is pulled out from the accommodating portion 21 , the first rib 32 prevents the water poured from the water pouring through hole 41 from flowing out to the side of the liquid container cover 31 .

Therefore, water leakage from the liquid container 23 can be suppressed with a simple structure.

As in the present embodiment, the first rib 32 is formed in the direction in which the liquid container 23 is pulled out, and may be extended toward the opening 35 .

Thereby, when the liquid container 23 is pulled out from the accommodating portion, the first rib 32 can guide the water filled into the liquid container lid to the opening portion 35 .

Therefore, water leakage from the liquid container 23 can be suppressed with a simple structure.

As in the present embodiment, as a part of the water injection portion, a second rib 42 formed to cover at least the side may be included.

With this configuration, the second rib 42 can suppress the water poured from the water pouring through hole 41 from flowing out to the side, and can guide the water to fall to the inner side of the first rib 32 .

Therefore, water leakage from the liquid container 23 can be suppressed with a simple structure.

As in the present embodiment, the lower end of the second rib 42 is formed to extend downward further than the upper end of the first rib 32 , and may be provided to be located further inward than the upper end of the first rib 32 .

With this configuration, it becomes difficult for the poured water to go over the first rib 32 , and thus it is possible to suppress the poured water from flowing out onto the upper surface of the liquid container cover 31 .

Therefore, water leakage from the liquid container 23 can be suppressed with a simple structure.

As in the present embodiment, a third rib 33 may be formed on the upper surface of the liquid container cover 31 at a lateral position of the first rib 32 so as to be arranged non-parallel to the direction in which the first rib 32 extends.

With this configuration, the third rib 33 stops the water that flows out of the upper surface of the liquid container cover 31 beyond the first rib 32 and causes it to flow out to the side, thereby preventing the water that flows out of the upper surface of the liquid container cover 31 from flowing out of the washing machine.

Therefore, water leakage from the liquid container 23 can be suppressed with a simple structure.

As in the present embodiment, the liquid container 23 includes: a groove portion 50 for storing multiple amounts of liquid; and a liquid chamber 29 for inputting a single amount of liquid, and a liquid container cover 31 covers the upper portion of the groove portion 50, and an opening portion 35 may be arranged in a manner opposite to the liquid chamber 29.

With this structure, the upper surface of the groove 50 storing multiple amounts of liquid can be blocked by the liquid container cover 31, and water can be poured into the liquid chamber 29 through the opening 35.

Therefore, in the integrally constructed liquid container 23, a tank 50 for storing multiple amounts of liquid and a liquid chamber 29 for injecting a single amount of liquid can be provided. (Other embodiments)

As described above, the first embodiment is described as an example of the technology of the present disclosure. However, the technology of the present disclosure is not limited thereto.

Therefore, other implementation forms are exemplified below.

In the first embodiment, a drum type washing machine is described as an example of a washing machine. Any washing machine can be provided with a liquid container. Therefore, the washing machine is not limited to a drum type washing machine, and may be a vertical type washing machine or a two-tank type washing machine.

In the first embodiment, as an example of the third rib, a plurality of third ribs 33 extending in a direction substantially perpendicular to the first rib 32 are described. The third rib only needs to be non-parallel to the direction in which the first rib extends. Therefore, it is not limited to a straight line structure extending substantially perpendicular to the first rib. For example, the third rib may also be a bent structure or a curved structure. However, the plurality of third ribs 33 extending in a direction substantially perpendicular to the first rib 32 shown in the first embodiment can suppress water from flowing forward and can guide water to the side, so the effect of suppressing water from flowing out of the washing machine is very high.

As described above, the present disclosure can be applied to a washing machine with a pull-out liquid container. Specifically, the present disclosure can be applied to a vertical washing machine, a drum washing machine, a two-tank washing machine, etc.
