DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first invention of the present invention will be described below with reference to the drawings by taking a toilet lid as an example. As shown in FIGS. 1 to 8, the hot water washing device of the present invention is mounted on a toilet bowl 1 and is configured by rotatably disposing a toilet lid a and a toilet seat b in a body case 2 containing a washing device body. is doing. One of the joints between the main body case 2 and the toilet lid a is provided integrally with the side surface of the toilet lid a so as to project outward to provide the toilet lid shaft 3 and the toilet lid shaft support hole 4 provided in the main body case 2. By inserting the toilet lid shaft 3 into the, the both are rotatably coupled. The other coupling portion is arranged inside the main body case 2, and the rotary shaft 7 of the toilet lid rotation speed reducer 6 fixed to the main body case 2 with the fixture 5 is

The toilet seat b is set so that the weight m _{B of the} toilet seat b is heavier than the weight m _{A of the} toilet lid a by increasing the plate thickness t of the resin material forming the toilet seat b. Reference numerals 16 and 17 denote an air supply port and a discharge port of the heating device 10.

In the above structure, when the toilet lid a and the toilet seat b are opened, they are manually lifted and opened. When closing the toilet lid a and the toilet seat b, the tips of the toilet lid a and the toilet seat b are gently pulled to the front, and the toilet lid rotation reduction device 6 and the toilet seat rotation reduction device 13 act to close the toilet lid a and the toilet seat b. It closes while suppressing rapid rotational movement.

On the other hand, the rotation center O _A of the toilet lid a and the toilet seat b
Rotation center O _B and l _A distance to the center of gravity from l _B of, also, each of the weight and m _A and m _B, the opening angle of the toilet lid a when the time closing of the toilet lid a set to 0 ° theta _A and toilet seat B

The rotational moments M _A and M _B about the circumference are M _A = l _A · m _A
It can be expressed by cos θ _A and M _B = 1 _B · m _B · cos θ _B. However, since both rotation reduction gears having substantially the same braking force are used and m _A <m _B while l _A ≈l _B , M _A <M _B. For this reason, the closing time of the toilet seat b becomes earlier than the closing time of the toilet lid a, and the collision between the toilet lid a and the toilet seat b at the time of closing can be prevented.

Next, an embodiment of the second invention of the present invention will be described with reference to the drawings. The hot water cleaning apparatus of the present invention is shown in FIG.
As shown in FIG. 9, the toilet lid 1 and the toilet seat b are rotatably arranged on the body case 2 which is placed on the toilet bowl 1 and contains the cleaning apparatus body. And the main body case 2 and the toilet lid a
One of the connecting portions of and is integrally provided with the side surface of the toilet lid a so as to project outward to provide the toilet lid shaft 3 and insert the toilet lid shaft 3 into the toilet lid shaft support hole 4 provided in the main body case 2. By doing so, both are rotatably connected. The other coupling portion is arranged inside the main body case 2, and the rotary shaft 7 of the toilet lid rotation speed reducer 6 fixed to the main body case 2 with a fixture 5 is attached to the main body case 2
It is rotatably coupled by penetrating through the toilet lid rotation shaft support hole 8 provided on the wall surface of the above and inserting it into the support 9 of the toilet lid a. On the other hand, a heating device 10 including an electric heater and a blower is built in the inside of the toilet lid.

Further, one of the connecting portions of the main body case 2 and the toilet seat b is integrally provided on the side surface of the toilet seat b so that the toilet seat shaft 11 is provided so as to project outward and the toilet seat shaft support hole 12 provided in the main body case 2 is provided. By inserting the toilet seat shaft 11 into the, the both are rotatably coupled. The other coupling portion is disposed inside the main body case 2 and has a toilet seat rotation reduction gear 13 having a smaller braking force than the toilet lid rotation reduction gear 6 via a toilet seat rotation shaft support hole 14 provided on the side surface of the toilet seat b. Toilet seat rotating shaft 15
It is rotatably connected by inserting. Further, the toilet seat b is set so that the weight mB of the toilet seat b is substantially equal to the weight mA of the toilet lid a by increasing the plate thickness t of the resin material forming the toilet seat b. Reference numerals 16 and 17 denote an air supply port and a discharge port of the heating device 10.

In the above structure, when the toilet lid a and the toilet seat b are opened, they are manually lifted and opened. When closing the toilet lid a and the toilet seat b, the tips of the toilet lid a and the toilet seat b are gently pulled to the front, and the toilet lid rotation reduction device 6 and the toilet seat rotation reduction device 13 act to close the toilet lid a and the toilet seat b. It closes while suppressing rapid rotational movement.

On the other hand, the rotation center O _A of the toilet lid a and the toilet seat b
Rotation center O _B and l _A distance to the center of gravity from l _B of, also, each of the weight and m _A and m _B, the opening angle of the toilet lid a when the time closing of the toilet lid a set to 0 ° theta _A and toilet seat B
If the opening angle of the toilet seat B when the closing time is 0 ° is θ _B , the rotation center O _A of the toilet lid a and the rotation center O _{B of the} toilet seat b are
The rotational moments M _A and M _B about the circumference are M _A = l _A · m _A
It can be expressed by cos θ _A and M _B = 1 _B · m _B · cos θ _B. However, since you are m _A ≒ m _B while l _A ≒ l _B,
Although M _A ≈ M _B , since the toilet seat rotation speed reducer 13 having a braking force smaller than the braking force of the toilet cover rotation speed reducer 6 is used, the closing time of the toilet seat b is shorter than the closing time of the toilet lid a. As a result, it is possible to prevent the collision between the toilet lid a and the toilet seat b at the closing time.

[0018]

As in the above-described embodiment, the hot water cleaning apparatus of the present invention uses both rotation reduction gears having substantially the same braking force, and the rotation moment of the toilet lid with respect to the center of rotation is larger than that of the toilet lid. Since it is set, the closing time of the toilet seat becomes earlier than the closing time of the toilet lid, it is possible to prevent the toilet lid from colliding with the toilet seat at the time of closing, and it is possible to suppress the generation of scratches and unpleasant sounds.

Further, since the rotating moments of the toilet lid a and the toilet seat b are set to be substantially equal and the braking force of the toilet seat rotation speed reducing device is made smaller than the braking force of the toilet lid rotation speed reducing device, the closing time of the toilet seat is less than that of the toilet lid. It becomes shorter than the closing time, the collision between the toilet lid and the toilet seat at the time of closing can be prevented, and the generation of scratches and unpleasant sounds can be suppressed.
