Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to toilet equipment provided with a mechanism for raising and lowering a toilet seat support member.
[0002]
[Prior art]
The toilet seat installed on the upper surface of the western-style toilet is attached to the western-style toilet so as to be rotatable in an up-and-down direction via a toilet seat support member.
[0003]
Dirt such as urine is infiltrated between the toilet seat support member and the upper surface of the Western-style toilet bowl, which is likely to cause odor. Therefore, a toilet seat support member that can move up and down with respect to a Western-style toilet and moves (floats) the toilet seat support member together with the toilet seat when cleaning the Western-style toilet has been proposed (Japanese Patent Laid-Open No. 2000-33051). ).

[Problems to be solved by the invention]
In the conventional toilet seat support member elevating device, the ascending speed or descending speed is constant from the start to the stop. In such a case, since the inertial force when the toilet seat support member reaches the upper limit or when it hits the upper surface of the toilet bowl, the impact applied to the device in the toilet seat support member is large. Therefore, it was necessary to improve the impact resistance of each device or its support member.
[0007]
An object of this invention is to provide the toilet equipment which can ease the impact resistance requested | required of the apparatus provided in a toilet seat support member, its support member, etc.
[0008]
[Means for Solving the Problems]
The toilet equipment of the present invention (Claim 1) includes a toilet seat support member (2) provided in a toilet body (1), a toilet seat (3e) supported by the toilet seat support member (2) so as to be able to be tilted, In a toilet facility having a lifting device (20) for lifting and lowering a toilet seat support member (2), the toilet seat support member (2) is made of a front base plate (3a) that can be lifted and lowered and made of a bottomless box-like synthetic resin.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. 1A and 1B are side views of a toilet facility according to an embodiment, in which FIG. 1A shows a state before the toilet seat support member floats, and FIG. 1B shows a state after the toilet seat support member floats. FIG. 2 is a perspective view of the toilet equipment, and FIG. 3 is a perspective view of the levitation unit.
[0015]
A toilet seat support member 2 is installed on a rear upper surface of a porcelain western-style toilet main body 1 so as to be able to move up and down, and a toilet seat 3e and a toilet lid 3f are attached to the toilet seat support member 2 so as to be rotatable in a tilting direction.
[0016]
In this embodiment, the toilet seat support member 2 has an outer shell formed by a front base plate 3a that can be raised and lowered and a cover 3d made of a bottomless box-like synthetic resin. The front base plate 3a is provided with hot water cleaning nozzles 10 and 11 and a motor-driven hot water switching valve device 12 for cleaning the human body with warm water. Further, an illumination 3g is provided on the bottom surface of the front base plate 3a for illuminating the lower region S when the toilet seat support member 2 floats. Although LED is suitable as this illumination 3g, it is not limited to this.
[0017]
Further, on the front base plate 3a, an electric opening / closing unit 13 for opening and closing the toilet seat 3e and the toilet lid 3f, a hot air fan 14 for blowing out hot air toward the human body part and drying it, and odor from the toilet bowl. A deodorizing fan 15 and a deodorizing cartridge 16 for deodorizing by sucking air are provided. Human body detection sensors 17 and 18 for detecting a human body approaching or sitting on the toilet body 1 are provided on the cover 3d.
[0018]
A rear base plate 4a is provided on the upper surface of the rearmost part of the toilet body 1 so that the rear side of the cover 3d covers from above. The rear base plate 4a includes a heater-equipped warm water tank 4b (shown only in FIG. 1) for supplying warm water to the warm water washing nozzle, and a motor-driven floating unit for pushing the toilet seat support member 2 up and down. 20, a room heating fan 21 including a heater and an electric fan, a power supply board 22, a control circuit board 23, a valve unit 24 for supplying water to a toilet bowl and a trap part, and the like are provided.
[0019]
As shown in FIG. 3, the levitation unit 20 includes a stepping motor 30, a pinion 31 fixed to the rotating shaft of the stepping motor 30, and a rack 32 that meshes with the pinion 31. The stepping motor 30 is fixed to the front base plate 3a. A frame 33 of the levitation unit 20 is erected from the rear base plate 4a, and a rack 32 is fixed to the frame 33. Although not shown, the frame 33 is provided with a pair of rails extending in the vertical direction, and a slider provided on the front base plate 3a is movable along the rails. As the stepping motor 30 rotates forward or backward, the front base plate 3a moves up or down.
[0020]
This hot water washing mechanism and the like are operated by a remote controller attached to the wall surface of the toilet room. This remote control is provided with a levitation switch for levitation operation of the levitation unit 20 and a lowering switch for lowering the levitation unit 20. Signals from the levitation switch and the lowering switch are input to the levitation unit control circuit provided on the control circuit board 23.
[0021]
When the levitation switch is operated, the levitation unit 20 pushes up the front base plate 3a of the toilet seat support member 2 to a predetermined height and stops in that state. When the toilet seat support member 2 is raised, the illumination 3g is turned on. Thereby, the lower space (lower area) S of the front part of the toilet seat support member 2 that has floated is illuminated. Since the lower region S is brightly illuminated in this way, the upper surface of the toilet body facing the lower region S, the lower surface of the front base plate 3a, and the like can be easily cleaned.
[0022]
When the lowering switch is operated, the levitation unit 20 operates to lower the front base plate 3a.
[0023]
In this embodiment, the rising speed is made lower than before at the end of the raising process of the toilet seat support member 2, and the lowering speed is made lower than before at the end of the lowering process. . That is, the control circuit for the levitation unit is provided with a counter that counts the number of pulses given to the stepping motor 30 from the start of rising and lowering of the front base plate 3a, and the current position of the front base plate 3a is accurately detected. Yes. At the end of the ascending process and the end of the descending process, the interval between pulses applied to the stepping motor 30 becomes longer, the rotation of the stepping motor 30 becomes slower, and the ascending speed and descending speed of the front base plate 3a are smaller than before. Become.
[0024]
For this reason, at the moment when the front base plate 3a reaches the ascending limit and stops and when the front base plate 3a descends and stops on the Western-style toilet body 1, the impact applied to each component of the toilet seat support member 2 is reduced. The impact resistance required for each of these constituent members and their mounting portions is alleviated. Further, since the toilet seat support member 2 is decelerated at the end of the lowering process, even if a rag or the like is left on the western-style toilet body 1, it can be removed without hurting.
[0025]
The ascending speed and descending speed of the front base plate 3a may be changed stepwise or may be changed continuously .
[0026]
【The invention's effect】
As the following, according to the present invention, it is possible to alleviate the impact resistance required for equipment and its supporting member or the like provided in the toilet seat supporting member.
