Description

Technical Field

[0001] The present invention relates to a washing water tank device in a toilet system.

Background Art

[0002] In recent years, in a washing water tank device, it has been an issue to accurately automate the opening operation of a drain valve. The applicant of this application has addressed this issue and obtained a patent for a drain valve operating device (Patent Document 1).

[0003] The patented invention is a drain valve operating device that opens the drain valve of a washing water tank device that supplies washing water to a toilet, and includes a first connecting member and a second connecting member each having one end connected to the drain valve, a rotary winding portion to which the other ends of the first connecting member and the second connecting member are connected, an operating portion that rotates the rotary winding portion, and a protective portion that slidably covers each of the first connecting member and the second connecting member. The protective portion has ends provided on the other end sides of the first connecting member and the second connecting member fixed thereto. The first connecting member is set at a first position wound by a predetermined length along the outer periphery of the rotary winding portion in the first direction in a state before the operating portion rotates the rotary winding portion in the first direction. The second connecting member is set at a second position wound by a predetermined length along the outer periphery of the rotary winding portion in the second direction in a state before the operating portion rotates the rotary winding portion in a second direction opposite to the first direction. When the operating portion rotates in the first direction, the rotary winding portion winds up the first connecting member set at the first position by a first amount in the first direction to pull up the drain valve by the first amount, enabling toilet washing in a first washing mode with a first washing water amount. When the operating portion rotates in the second direction, the rotary winding portion winds up the second connecting member set at the second position by a second amount equal to the first amount in the second direction to pull up the drain valve by the second amount, enabling toilet washing in a second washing mode with a second washing water amount different from the first washing water amount.

[0004] According to this invention, when performing the first and second washing modes, each with different amounts of washing water, the operating unit can be simply rotated in different directions by the same amount of rotation according to the desired washing mode, allowing for easy switching between different washing modes using a common rotating winding unit.

[0005] Furthermore, according to this invention, the rotating winding unit winds either the first connecting member or the second connecting member by the same amount depending on the washing mode, thereby enabling accurate opening of the drain valve by a constant lifting amount regardless of the washing mode, and allowing easy execution of toilet flushing in different washing modes.

[0006] [Patent Document 1] Patent No. 6886615 [Overview of the project] [Problems that the invention aims to solve]

[0007] While diligently studying how to realize a low-profile toilet system, the inventors of this case discovered that modifying and adopting the configuration of the drain valve operating device disclosed in Patent Document 1 is effective in reducing the height of the flushing water tank device.

[0008] The present invention was conceived based on the above findings. The object of the present invention is to provide a low-profile type cleaning water tank device equipped with a water supply valve for supplying cleaning water and a drain valve for discharging the cleaning water. [Means for solving the problem]

[0009] The present invention relates to a low-profile type flushing water tank device comprising a water supply valve for supplying flushing water and a drain valve for discharging the flushing water, further comprising a first connecting member and a second connecting member, each having one end connected to the drain valve, a rotating winding section to which the other ends of the first connecting member and the second connecting member are connected, and an operating section for rotating the rotating winding section in both directions, wherein when the operating section rotates the rotating winding section in a first direction, the rotating winding section winds the first connecting member by a first amount in the first direction, thereby raising the drain valve by the first amount and performing a first flushing mode toilet flush with a first flushing water volume, and when the operating section rotates the rotating winding section in a second direction, the rotating winding section winds the second connecting member by a second amount in the second direction, thereby raising the drain valve by the second amount and performing a second flushing mode toilet flush with a second flushing water volume.

[0010] According to the present invention, a low-profile type washing water tank device can be realized by employing a drain valve operating device that includes the first connecting member, the second connecting member, the rotating winding unit, and the operating unit.

[0011] In particular, it is preferable that the upper wall surface of the washing water tank device is flat.

[0012] According to this, the cleaning water tank device can be easily housed inside a cabinet or the like.

[0013] In the drain valve operating device disclosed in Patent Document 1, the water supply pipe and power supply unit were projected upward from the upper wall surface of the tank. According to the present inventor, by arranging these elements so as to penetrate the side wall surface of the tank, the upper wall surface of the tank can be made flat.

[0014] Furthermore, it is preferable that the operating unit is an electrically driven motorized operating unit.

[0015] According to this, the operation of opening the drain valve can be precisely automated.

[0016] Further, the rotary winding portion and the operation portion are supported on the front wall surface of the tank of the washing water tank device via one or more brackets, and a part of the water supply hose from the water stop valve to the water supply valve is preferably disposed on the rear side of the rotary winding portion and the operation portion.

[0017] According to this, while the rotary winding portion and the operation portion can be stably supported, there is no hindrance to the handling of the water supply hose.

[0018] Further, by manually operating the first swing arm, the drain valve is lifted by the first amount, and toilet washing in the first washing mode with the first washing water amount is executed. By manually operating the second swing arm, the drain valve is lifted by the second amount, and toilet washing in the second washing mode with the second washing water amount is preferably executed.

[0019] According to this, manual operation of the drain valve can be used in combination.

[0020] The present invention also relates to a toilet system comprising a washing water tank device having any of the above features and a flush toilet connected to the washing water tank device.

Advantages of the Invention

[0021] According to the present invention, by adopting a drain valve operating device including the first connecting member, the second connecting member, the rotary winding portion, and the operation portion, a wash water tank device of the low siphon type can be realized.

Embodiments for Carrying Out the Invention

[0023] (Overall Configuration) Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a washing water tank device 1 according to an embodiment of the present invention, and FIG. 2 is a partial enlarged view of FIG. 1. Further, FIG. 3 is a plan view of the washing water tank device 1 according to the present embodiment.

[0024] The washing water tank device 1 of the present embodiment shown in FIGS. 1 to 3 is supported by a frame unit 3, has a width of 160 mm and a height of 820 mm in the front-rear direction (Note for proofreading: Please add a note if it can be exemplified), and the upper wall surface of the tank is flat. Therefore, it can be mounted on a low-sill type toilet system as a low-sill type washing water tank device.

[0025] As shown in Figures 1 to 3, water supplied from the water supply pipe 11, which penetrates the left wall of the tank of the flushing water tank device 1, reaches the water supply valve 14 of the flushing water tank device 1 via a shut-off valve 12 and a water supply hose 13 located inside the flushing water tank device 1, and is supplied to the inside of the flushing water tank device 1 from the water supply valve 14. Then, each time the drain valve 15 is operated by the operation of the automatic flushing unit 2, which will be described later, the water is drained as flushing water into a flush toilet (not shown) connected to the flushing water tank device 1.

[0026] Furthermore, the power supply unit 4 is installed so as to penetrate the right wall of the tank of the washing water tank device 1.

[0027] With the arrangement of the water supply pipe 11 and the power supply unit 4 as described above, the upper wall surface of the washing water tank device 1 is flat.

[0028] (Automatic cleaning unit 2) Figure 4 is an exploded view of the automatic cleaning unit 2. As shown in Figure 4, the automatic cleaning unit 2 has a first wire 21 as a first connecting member and a second wire 22 as a second connecting member.

[0029] One end of the first wire 21 and the second wire 22 are connected to the drain valve 15, and the other end of the first wire 21 and the second wire 22 are connected to the pulley 23, which serves as a rotating winding unit.

[0030] The pulley 23 is positioned approximately horizontally and is rotated in both left and right directions around a vertical axis by the operating unit 26. In this embodiment, the operating unit 26 in the cleaning water tank device 1 is an electrically driven motorized operating unit.

[0031] FIG. 5 is a diagram for explaining the operation of the auto cleaning unit 2. When the operation unit 26 rotates the pulley 23 in the first direction (right direction in FIG. 5) from the initial state (the state in FIG. 5(a)), the pulley 23 winds up the first wire 21 by the first amount in the first direction, so that the drain valve 15 is pulled up by the first amount and the toilet cleaning in the first cleaning mode with the first cleaning water amount is executed. After holding the pulley 23 at the position in FIG. 5(b) for a predetermined time corresponding to the first cleaning water amount, the operation unit 26 rotates the pulley 23 in the reverse direction to return it to the original initial state (the state in FIG. 5(c)).

[0032] Although illustration is omitted, symmetrically, when the operation unit 26 rotates the pulley 23 in the second direction (left direction in FIG. 5) from the initial state (the state in FIG. 5(a)), the pulley 23 winds up the second wire 22 by the second amount (the difference or similarity with the first amount is arbitrary) in the second direction, so that the drain valve 15 is pulled up by the second amount and the toilet cleaning in the second cleaning mode with the second cleaning water amount (usually different from the first cleaning water amount) is executed. After holding the drain valve 15 at the lift position for a predetermined time corresponding to the second cleaning water amount, the operation unit 26 rotates the pulley 23 in the reverse direction to return it to the original initial state.

[0033] Returning to FIG. 4, the auto cleaning unit 2 further includes a cover 24 for protecting the pulley 23, a case 25 having a rotation angle restricting portion of the pulley 23, and a bracket portion 27 for fitting the auto cleaning unit 2 to the fixing bracket 6.

[0034] Next, FIGS. 6 and 7 are diagrams for explaining the fixing bracket 6 for fixing the auto cleaning unit 2 to the front wall surface of the tank.

[0035] As shown in FIGS. 6 and 7, the fixing bracket 6 has a flat shape in the form of the Chinese character 'Ri' (日), and the corresponding convex portions 27a, 27b of the bracket portion 27 of the auto cleaning unit 2 are fitted and fixed in the window-shaped cavity portions 6a, 6b arranged vertically.

[0036] Furthermore, screw holes 6c to 6e are provided at one location on the upper side and two locations on the lower side of the fixing bracket 6. Screws (not shown) that penetrate the front wall surface of the tank are screwed into these screw holes 6c to 6e, thereby fixing the fixing bracket 6 (and the automatic cleaning unit 2) to the front wall surface of the tank.

[0037] Here, both the height of the automatic cleaning unit 2 and the height of the fixing bracket 6 are low, and they fit above a height of 275 mm below the upper edge of the cleaning water tank device 1 (the overflow height of the drain valve 15), making them suitable for installation in a low-profile type cleaning water tank device 1. Furthermore, there is no risk of the lower parts of the automatic cleaning unit 2 and the fixing bracket 6 being submerged in the cleaning water inside the cleaning water tank device 1.

[0038] Furthermore, referring to Figures 2 and 3, in the cleaning water tank device 1 of this embodiment, a portion of the water supply hose 13, which extends from the shut-off valve 12 to the water supply valve 14, is located on the rear side of the automatic cleaning unit 2. This is also advantageous when designing the cleaning water tank device 1 as a low-profile type.

[0039] (Manual operation section 7) Referring to Figures 2 and 3, the cleaning water tank device 1 of this embodiment also includes a manual operation unit 7. Figure 8 is a perspective view of the manual operation unit 7. As shown in Figure 8, the manual operation unit 7 has a first swing arm 71 which performs the same function as operating the drain valve 15 by the first wire 21, and a second swing arm 72 which performs the same function as operating the drain valve 15 by the second wire 22.

[0040] In other words, by manually operating the first swinging arm 71, the drain valve 15 can be raised by a first amount, and toilet flushing in a first flushing mode with a first flushing water volume can be performed, and by manually operating the second swinging arm 72, the drain valve 15 can be raised by a second amount, and toilet flushing in a second flushing mode with a second flushing water volume can be performed.

[0041] Figure 9 illustrates the operation of the first swing arm 71 of the manual operation unit 7. As shown in Figures 8 and 9, the first swing arm 71 is designed to lift the drain valve 15 by pressing the manual operation unit 7 from above or by pressing the manual operation unit 7 from the front.

[0042] Similarly, as shown in Figure 8, the second swing arm 72 can also lift the drain valve 15 by pressing it from above the manual operation unit 7 or by pressing it from the front of the manual operation unit 7.

[0043] Therefore, the position of the pressing part (e.g., a push button) for the manual operation unit 7 can be appropriately selected from the front and rear of the cleaning water tank device 1, in accordance with the design of the cabinet or the like that houses the cleaning water tank device 1.

[0044] Furthermore, the manual operation unit 7 of the cleaning water tank device 1 of this embodiment is provided with hooks 73 to 76 for routing the power supply cable, as clearly shown in Figure 10. By routing the power supply cable using these hooks 73 to 76 (see Figure 11), the risk of the power supply cable interfering with other movable elements can be significantly reduced.

[0045] (Effects and Benefits) As described above, this embodiment makes it possible to realize a low-profile type cleaning water tank device 1 by employing an automatic cleaning unit 2 (drain valve operating device) that includes a first wire 21 (first connecting member), a second wire 22 (second connecting member), a pulley 23 (rotating winding part), and an operating part 26.

[0046] Furthermore, the upper wall surface of the cleaning water tank device 1 in this embodiment is flat. This makes it easy to house the cleaning water tank device 1 inside a cabinet or the like.

[0047] Furthermore, the operating unit 26 of the washing water tank device 1 in this embodiment is an electrically driven motorized operating unit. This makes it possible to accurately automate the opening operation of the drain valve 15.

[0048] Furthermore, the pulley 23 (rotating winding section) and operating section 26 of this embodiment are supported on the front wall surface of the tank of the cleaning water tank device 1 via the bracket section 27 and the fixing bracket 6, and a portion of the water supply hose 13, which runs from the stopcock 12 to the water supply valve 14, is positioned behind the pulley 23 (rotating winding section) and operating section 26. This allows for stable support of the pulley 23 (rotating winding section) and operating section 26, while preventing any interference with the routing of the water supply hose 13.

[0049] Furthermore, according to the flushing water tank device 1 of this embodiment, by manually operating the first swinging arm 71, the drain valve 15 is raised by a first amount, and toilet flushing in the first flushing mode with a first flushing water volume is performed. By manually operating the second swinging arm 72, the drain valve 15 is raised by a second amount, and toilet flushing in the second flushing mode with a second flushing water volume is performed. This allows for the combined use of manual operation of the drain valve.
