Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heated toilet seat that is attached to a Western-style toilet bowl to heat a user's kidneys and the like.

2. Description of the Related Art Conventionally, a heating toilet seat of this kind has been disclosed, for example, in Japanese Utility Model Publication No. Sho 59-3240.
As shown in Japanese Patent Publication No. 0, the structure is as shown in FIG. 6 and FIG. 7 showing a schematic cross section thereof.

That is, a base 2 having a fixing member to the toilet bowl 1, a case 4, a toilet seat 6 in which a heater 5 is provided, and a toilet pig 7 covering the toilet seat 6 are provided with a rotating shaft 8. And E
It was rotatably fixed to the case 3 on the ring 9.
The base 2 and the case 3 are mechanically fixed from the side of the base 2 with a screw 10, and a control device 11 for controlling the energization of the heater 5 is attached to the upper wall of the inner surface of the case 3 inside thereof. Even if water or sewage enters the main body 4, the control circuit 11 is not directly exposed to the water or sewage.

Problems to be Solved by the Invention However, in the case of such a configuration, when water or dirty water enters the body 4, even if it is prevented that the control device 11 is directly exposed to water, It was not possible to prevent the electric parts such as the control device 11 from being damaged by the steam generated when the sewage was evaporated. In particular, the area around the toilet bowl is often cleaned with hydrochloric acid-based detergent, and in that case, the vapor of hydrochloric acid is generated from the detergent attached to the toilet bowl 1 or the detergent stored in the gap 12 between the base 2 and the toilet bowl 1. However, there is a case where it penetrates into the inside of the main body 4 through the fitting gap 13 between the case 3 and the base 2 and rises, corroding the defenseless control device 11 and the like mounted on the upper wall of the inner surface of the case 3 and causing it to malfunction.

Therefore, the present invention provides water and sewage (such as urine and detergent) and
Even if those vapors penetrate into the main body, they prevent the control device from corroding.

Means for Solving the Problems And the means for solving the above problems according to the present invention is that a base is provided with an enclosure formed by an integrally formed rising wall, and a control device is mounted in the enclosure, and an upper portion thereof is provided. Therefore, it is covered with an inner cover different from the outer cover.

Action The action of this technical means is as follows.

That is, since the control device is installed in the enclosure formed by the rising wall formed integrally with the base, even if water or dirty water enters the main body, it does not flow into the enclosure and the control device is exposed to water. Never. In addition, since it is covered with an inner cover from above the control device, even if water or sewage that has entered the body is vaporized or hydrochloric acid vapor enters the body from the gap between the outer cover and the base, those Control devices are not affected by corrosive gases. That is, the control device is completely protected against the intrusion of water, dirty water, and corrosive gas, and can prevent failures and accidents due to corrosion, electric leakage, and the like.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective exploded view of a heating toilet seat showing an embodiment, and 14 is a toilet seat in which an electric heater 15 is arranged and which is warmed from the surface when a user sits down. 1
Reference numeral 6 is a base, and 17 is a case that serves as an outer cover. The base 16 and the case 17 form an outer shell of the main body 18. Reference numeral 19 is a toilet lid for covering the toilet seat 15 when not in use.

2, 3, and 4 are all sectional views of the main part of the main body 18, FIG. 2 is a longitudinal cross-section of the main body 18, and FIG. 3 is the vicinity of AA of FIG. Cross section, 4th
The figure shows a cross section taken along the line BB in FIG. 20
Is a control device that controls energization to the electric heater 15 to control the surface temperature of the toilet seat 14, and various electronic components and a temperature control volume 22 are provided on the printed board 21.
Is installed. The controller 20 uses the electric heater 15
Also, a lead wire 23 is electrically connected to a temperature detecting element (not shown) provided near the electric heater 15. As shown in FIG. 4, the lead wire 23 penetrates the inside of the ear portion 24 provided at the rear end portion of the toilet seat 14 and the rotary shaft 25 press-fitted and fixed to the ear portion 24 from the inside of the toilet seat 14 to the main body 18.
It is guided in and is connected to the control device 20 by connectors 26 and 27. Lead wire 23 passing through the rotation shaft 25
Are protected by a protective tube 28. A cam 29 is integrally provided at the tip of the rotating shaft 25, and when the toilet seat 14 is rotated and leaned against and is almost upright, such as for men's small use, this cam 29 is attached to the base 16 below. It is pressed against the spring plate 30 to prevent the toilet seat 14 from falling down. A rotary shaft 31 is provided integrally with the ear portion 32 at a position facing the rotary shaft 25. The rotating shaft 31 is inserted with a clearance into the lateral hole 34 of the wall 33 that is integrally raised from the base 16, and the rotating shaft 25 is integrally raised from the base 16 and placed on a wall 33 'having a substantially U-shaped groove on the upper surface. The toilet seat 14 is rotatably held by the base 16, that is, the main body 18, by being supported by the pressing tool 35 from above with a clearance as well. The base 16 has
An enclosure is formed by a rising wall 36 integrated with the base 16 so as to enclose the control device 20, the lead wire 23 and the spring plate 30, and an inner cover 37 is provided from above to cover the control device 20, the lead wire 23, the cam 29, The spring plate 30 and the press fitting 35 are provided so as to be inserted, and are fitted to the rising wall 36 and fixed by screws 38. The control device 20 is sandwiched and fixed by a boss 39 rising from the base 16 and a boss 40 hanging from the inner cover 37. Reference numeral 41 is a power cord for supplying power, and the molded cord outlet portion 42 is the cutout portion 4 of the inner cover 37.
3 and is sandwiched between and fixed to the rising wall 36 of the base 16. The adjusting volume 22 fixed directly to the printed board 21 is also fixed to the rising wall 36 with the nut 44, and is inserted into the shaft 47 of the adjusting knob 46 which is guided through the lateral hole 45 provided in the case 17. ing. By rotating the adjustment knob 46 by the user, the resistance value of the adjustment volume 22 is changed,
The surface temperature of the toilet seat 14 can be adjusted.

The case 17 has two claw portions 48 on the inner surface of the side, and is fixed to the arc portions 49 at both ends of the base 16 by locking. Further, a pair of mounting bolts 50 for attaching to a toilet seat (not shown) are provided on the lower surface of the base 16.
