[0009] Hereinafter, the first embodiment will be described with reference to the drawings.

[0010] 1 shows the overall configuration of a water circulation system 12 according to the technology of the present disclosure. This water circulation system 12 is a system that circulates and purifies wastewater used in the home, for example, so that the wastewater can be reused in the home. Examples of wastewater include water used in water usage points 14 in the home, such as a bathroom, a flushing toilet seat, a toilet, etc.

[0011] The water circulation system 12 has a wastewater tank 100 , a biological treatment tank 300 , and a treated water tank 400 .

[0012] The wastewater passes through a wastewater tank 100, a biological treatment tank 300, and a treatment tank 400 in this order, and is then circulated to a water usage point 14 (such as a washroom, a bath, or a toilet seat with a flushing function).

[0013] The water usage points 14 and the drainage tank 100 are connected by drainage piping 102. Wastewater generated at the water usage points 14 is sent to the drainage tank 100 through the drainage piping 102.

[0014] In the drainage tank 100, predetermined treatment such as stirring is performed on the drainage water. The gas in the drainage tank 100 may be discharged to the outside of the drainage tank 100, for example, by driving a fan.

[0015] The drainage tank 100 and the biological treatment tank 300 are connected by a drainage pipe 302. The drainage in the drainage tank 100 is sent to the biological treatment tank 300 through the drainage pipe 302 by driving a drainage pump 110.

[0016] A filtration device, for example, is provided inside the biological treatment tank 300. The filtration device can filter the wastewater. The gas inside the biological treatment tank 300 may be discharged to the outside of the biological treatment tank 300 by, for example, driving a fan.

[0017] The biological treatment tank 300 and the treated water tank 400 are connected by a treated water pipe 402. A treated water pump 406 is provided on the treated water pipe 402. When the treated water pump 406 is driven, wastewater from the biological treatment tank 300 is sent to the treated water tank 400.

[0018] A predetermined treatment is also performed on the wastewater in the treatment water tank 400. The gas in the treatment water tank 400 may be discharged to the outside of the treatment water tank 400, for example, by driving a fan.

[0019] The treated water tank 400 and each of the water usage points 14 are connected by a supply pipe 716. A supply pump 724 is provided on the supply pipe 716. The treated water in the treated water tank 400 is sent to each of the water usage points 14 through the supply pipe 716 by driving the supply pump 724. Note that in practice, the supply pipe 716 may branch out toward each of the water usage points 14.

[0020] Fig. 2 shows a liquid treatment device 16 according to the technology of the present disclosure. The example shown in Fig. 2 is shown as an example of the liquid treatment device 16 incorporated in the water circulation system 12 shown in Fig. 1. The liquid treatment device 16 is an example of the fluid treatment device of the technology of the present disclosure. The fluid to be treated by the fluid treatment device may be a gas as well as a liquid.

[0021] The liquid treatment device 16 has a rectangular parallelepiped housing 18. In the following, the width direction, depth direction, and height direction of the housing 18 are indicated by arrows W, D, and H, respectively.

[0022] Within the housing 18, various devices for operating the liquid treatment device 16, a wastewater tank 100, a biological treatment tank 300, and a treated water tank 400 are arranged.

[0023] 2, the outer portion of the housing 18 is a wall surface portion 28. Specifically, the wall surface portion 28 is a planar wall portion on six sides of the housing 18, that is, the front side, the back side, the right side, the left side, the upper side, and the lower side.

[0024] In this embodiment, the opening / closing member 30 and the container holder 52 are disposed on the wall portion 28 on the front side.

[0025] A sliding member may be provided on the lower side of the opening / closing frame 34 so that the opening / closing frame 34 can slide relative to the housing 18.

[0026] As shown in FIG. 4, a container holder 52 is provided at the front part 50 of the housing 18. In the illustrated example, the container holder 52 is a box-shaped or frame-shaped member with an open upper side. In this embodiment, two container holders 52 are arranged side by side in the width direction of the housing 18. The container holder 52 can hold a container 54 containing a liquid agent used in the water circulation system 12. The container holder 52 holds an ethanol bottle or a chlorine bottle as an example of the container 54. Note that the container holder is not limited to a box-shaped member, and may be structured to hold the container 54 by grasping it from the side. Furthermore, the container holder may be structured to be disposed on the upper side of the container 54 and to grasp the upper part of the container 54. For example, in a configuration in which a member other than the liquid agent is contained in the container 54 and this member is taken out from the lower side of the container 54, it is preferable that the upper part of the container 54 is held by the container holder. In short, the position at which the container 54 is held by the container holder is not limited.

[0027] A tube is connected to the container 54, and a supply hole is formed in the container 54. The supply hole is usually closed with a cap 58 (see FIG. 4), but by removing the cap 58, it is possible to supply the corresponding liquid agent to each container 54.

[0028] Each of the container holders 52 is attached to the front portion 50 by a hinge 60. As shown by the two-dot chain line in Fig. 4, the container holders 52 can rotate around the pins of the hinges 60 in the direction of the arrow R1 and in the opposite direction. However, when the opening / closing member 30 is in the closed position P1, the opening / closing member 30 prevents the container holders 52 from rotating in the direction of the arrow R1.

[0029] In contrast, when the opening / closing member 30 is in the open position P2, the container holder 52 can rotate in the direction of the arrow R1. When the container holder 52 is rotated in the direction of the arrow R1, the upper part of the container holder 52 tilts toward the front in the depth direction. When the container holder 52 rotates in this manner, the container 54 held by the container holder 52 also rotates in the direction of the arrow R1, i.e., in a direction in which the upper part tilts toward the front in the depth direction.

[0030] A push-up piece 64 is provided on the front portion 50 at a position lower than the container holder 52. In the example shown in Fig. 4, the push-up piece 64 protrudes forward from the front portion 50, and the tip side further protrudes upward. The upper end of the push-up piece 64 contacts the bottom of the container 54 through an opening formed in the bottom plate of the container holder 52. The push-up piece 64 is an example of a push-up member.

[0031] When container holder 52 rotates in the direction opposite to the arrow R1, its upper portion faces upward and container 54 held by container holder 52 assumes a position that is not tilted. In this state, a part of housing 18 is positioned above container holder 52 and container 54 so as to cover them.

[0032] When container holder 52 is rotated in the direction of arrow R1, bottom plate 52B of container holder 52 moves downward, but the height position of push-up piece 64 remains unchanged. Therefore, container 54 is pushed upward relative to container holder 52 by push-up piece 64. In other words, container 54 takes a position in which it projects upward from container holder 52.

[0033] In this embodiment, the multiple container holders 52 are independently rotatable by hinges 60 in the direction of arrow R1 and in the opposite direction.

[0034] The container holder 52 can be accessed from the housing 18, and the container 54 can be attached and detached. When the opening / closing member 30 is in the closed position P1, the attachment / detachment opening 62 is blocked by the opening / closing member 30. When the opening / closing member 30 is in the open position P2, the attachment / detachment opening 62 is opened, and the container 54 can be attached and detached to the container holder 52. Furthermore, when the opening / closing member 30 is in the open position P2, the container holder 52 rotates, so that the upper part of the container 54 is tilted toward the attachment / detachment opening 62, making it easy to attach and detach the container 54.

[0035] Next, the operation of this embodiment will be described.

[0036] As shown in Figure 4, in the liquid treatment device 16, the opening / closing member 30 is moved to the open position P2 to open the attachment / detachment opening 62, making it possible to attach and detach the container 54 to the container holder 52, and to refill the attached container 54 with liquid.

[0037] Since the container holder 52 is arranged on the wall portion 28 of the housing 18, it is easy to attach and detach the container 54 to the container holder 52, and to refill the attached container 54 with liquid, resulting in high workability.

[0038] The height position of container holder 52 from bottom end 18B (see FIG. 3) of housing 18 is not particularly limited as long as it allows easy attachment and detachment of container 54 to container holder 52 and easy refilling of attached container 54 with liquid agent. For example, height H1 from the installation surface on which housing 18 is installed to bottom plate 52B (bottom end) of container holder 52 is preferably 500 mm or more and 1500 mm or less, and more preferably 800 mm or more and 1200 mm or less.

[0039] The liquid treatment device 16 may be installed with a stand or casters between the installation surface and the housing 18. Even in this case, if the position of the container holder 52 is set so that the height H1 from the installation surface to the bottom plate 52B of the container holder 52 is within the above-mentioned range, it is easy to attach and detach the container 54 to the container holder 52 and to refill the attached container 54 with the liquid agent.

[0040] Also, liquid processing device 16 may be placed in a recess formed in the installation surface. Even in this case, if the position of container holder 52 is set so that height H1 from the installation surface to bottom plate 52B of container holder 52 is within the above-mentioned range, it is easy to attach and detach container 54 to container holder 52 and to refill attached container 54 with liquid agent.

[0041] The housing 18 of the liquid treatment device 16 has an attachment / detachment opening 62. The container 54 can be attached to and detached from the container holder 52 through this attachment / detachment opening 62.

[0042] The housing 18 has an opening / closing member 30. The opening / closing member 30 can be set to a closed position to close the attachment / detachment opening 62. When the attachment / detachment opening 62 is closed, the outer surface of the housing 18 is covered with the opening / closing member 30, which improves the appearance. Then, by moving the opening / closing member 30 to an open position, the attachment / detachment opening 62 is opened, and the container 54 can be attached to and detached from the container holder 52, and the container 54 can be refilled with a liquid agent.

[0043] In this embodiment, the opening and closing member 30 is provided for a plurality (two) of container holders 52. Therefore, a structure in which the opening and closing members 30 are provided corresponding to a plurality of container holders 52 can be realized.

[0044] The liquid treatment device 16 has a hinge 60. The hinge 60 is an example of a rotation support member, and rotatably holds the container holder 52. By rotating the container holder 52, the held container 54 can be tilted to the front side, i.e., toward the attachment / detachment opening 62, making it easy to attach and detach the container 54 to and from the container holder 52, and to refill the container 54 with liquid and other components.

[0045] The multiple container holders 52 are supported by hinges 60 so as to be rotatable separately from the housing 18. The multiple container holders 52 can be rotated independently. For example, only the container holder 52 corresponding to the container 54 to be attached or detached can be rotated, while the other container holders 52 cannot be rotated, improving the workability of the attachment and detachment operation.

[0046] The liquid treatment device 16 has a push-up piece 64. The push-up piece 64 pushes the container 54 upward relative to the container holder 52 in a state in which the container holder 52 is rotated by the hinge 60. That is, the container 54 moves in a direction away from the bottom plate 52B of the container holder 52. As a result, the container 54 comes closer to the attachment / detachment opening 62 compared to a case in which the container 54 is not pushed upward, facilitating the attachment / detachment of the container 54 and the refilling of the container 54 with a liquid agent.

[0047] It should be noted that the push-up member according to the disclosed technology is not limited to the push-up piece 64 described above. For example, a link mechanism that is linked to the rotation of the container holder 52 may be provided, and the link mechanism may push up the container 54. Alternatively, a spring that urges the container 54 upward and a locking mechanism that locks the upward movement of the container 54 may be provided, and the locking mechanism may be released when the container holder 52 is rotated in the direction of the arrow R1, thereby moving the container 54 upward by the urging force of the spring.

[0048] In this embodiment, the container holder 52 is rotatable separately from the opening and closing operation of the opening and closing member 30. In contrast, it is also possible to configure the container holder 52 to rotate in conjunction with the opening and closing operation of the opening and closing member 30. For example, by connecting the opening and closing member 30 and the upper part of the container holder 52 with a link, a configuration can be realized in which the container holder 52 rotates so that the upper part of the container holder 52 moves forward in conjunction with the opening and closing member 30 moving to the open position. This eliminates the need for the task of rotating the container holder 52, improving workability.

[0049] In the disclosed technology, even in a structure that does not have an opening / closing member 30 and a structure in which the container holder 52 does not rotate by a hinge 60 or the like, as long as the container holder 52 is disposed on the wall surface portion 28 of the housing 18, it is easy to attach and detach the container 54 to and from the container holder 52, and to refill the container 54 with a liquid agent. For example, even if the container holder 52 is fixed to the housing 18 and is configured to be immovable relative to the housing 18, if an attachment / detachment opening 62 is provided in the housing 18, the container 54 can be attached and detached to the container holder 52 through the attachment / detachment opening 62. Furthermore, even in a structure without the attachment / detachment opening 62, as long as a refilling opening for refilling the container 54 with a liquid agent is provided in the housing 18, the liquid agent can be refilled into the container 54 through the refilling opening.

[0050] In the above disclosure, the wall surface portion 28 on the front side has been exemplified as an example of the wall surface portion 28 on which the container holder 52 is arranged. The wall surface portion 28 on which the container holder 52 is arranged may be the wall surface portion 28 on the back side, right side, left side, upper side, or lower side. For example, when the dimensional height of the liquid processing device 16 is low or when the liquid processing device 16 is installed in a recessed portion of the installation surface, the position of the upper wall surface portion 28 (top surface) may be a height position that is easy for an operator to work at. In this case, the container holder 52 may be arranged on the upper wall surface portion 28 (top surface). Then, the opening and closing member 30 may be provided on the upper wall surface portion 28.
