As a result, the upper case and the lower case are in close contact with each other, so that dirt cannot be easily accumulated .

  In the fifth aspect of the invention, in particular, the sealing agent is applied to the joining slope of any one of the first to fourth aspects of the invention, so that water can be prevented from entering the cavity of the toilet seat, and the electrical components inside the toilet seat can be protected. Of course, corrosion from the metal cut surface can also be prevented.

(Embodiment 1)
FIG. 1 is a perspective view of a heating toilet seat according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of an essential part of the heating toilet seat.

  As shown in FIG. 1, the heating toilet seat has a main body 11 attached to a toilet 10 installed in a toilet room, and a toilet seat 20 and a toilet lid 12 are rotatably provided on the main body 11.

  As shown in FIG. 2, the toilet seat 20 is formed by pressing an upper plate 21 having a substantially arch shape in cross section of an aluminum plate having a thickness of 1.0 mm, and an outer peripheral edge 21 a and an inner peripheral edge of the upper case 21. The end faces of 21b are respectively bent at an angle of 45 degrees with respect to the horizontal plane to provide joint slopes 21c and 21d having a predetermined width, and the joint slope 21c of the outer peripheral edge 21a is fixed in a substantially rectangular shape at a predetermined interval. A hole 21e is provided.

  The outer peripheral edge 22a and the inner peripheral edge 22b of the lower case 22 made of resin are formed with joint slopes 22c and 22d of 45 degrees with respect to the horizontal plane that comes into contact with the joint slopes 21c and 21d of the upper case 21, respectively. A fixing claw 22e is provided at a position corresponding to the fixing hole 21e at an inner end portion of the joining slope 22c, and a rib that is substantially V-shaped with the joining slope 21d at an inner end portion of the joining slope 21d of the inner peripheral edge 22b. 22f is formed.

  As described above, the slopes of the joint slopes 21c, 21d of the upper case 21 and the joint slopes 22c, 22d of the lower case 22 are both 45 degrees, but the slopes of the joint slopes 21c, 21d of the upper case 21 are The inclination angle of the joint slopes 22c and 22d of the lower case 22 is 45 degrees or 45 degrees or more. By setting the inclination angle in this way, the joining slope always comes into contact with the outside, so that no gap is generated on the outside.

  The joint slopes 21c and 21d of the upper case 21 and the joint slopes 22c and 22d of the lower case 22 are combined in a state where they are in contact with each other via a silicon sealant, and the fixing claw 22e is fitted into the fixing hole 21e so that the upper case 21 and the lower case 22 are fixed. Further, the end portions of the joining slope 21d of the inner peripheral edge 21b of the upper case 21 are in contact with the ribs 22f of the lower case 21, whereby the inner peripheral edges 21b and 22b of the upper case 21 and the lower case 22 are positioned.

  A cavity 25 formed by the upper case 21 and the lower case 22 incorporates a lamp heater 32 as a heating element for warming the toilet seat. The lamp heater 32 is controlled by a control unit (not shown) installed in the main body 11. It is the structure which can control electricity supply.

  About the heating toilet seat comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Applying an appropriate amount of silicon sealing material (not shown) to the lower case 22 joining slopes 22c, 22d incorporating the lamp heater 32, overlaying the upper case 21 on top of it, and fitting the fixing claws 22e into the fixing holes 21e. Thus, the upper case 21 and the lower case 22 are fixed.

  As described above, in the present embodiment, the joint portion between the inner peripheral edge and the outer peripheral edge of the upper case 10 is provided at an angle of 45 degrees with respect to the horizontal direction from the outside of the toilet seat toward the inside of the cavity. The side appearance of the joint is visually invisible and the appearance is good over the entire circumference. In addition, since the joint slopes are set so that the outer periphery outside the inner side of the cavity comes into contact first, it is difficult to collect dirt due to close contact.

  Since the upper case 21 has an arch shape and is joined by a slope, the deformation can be greatly reduced with respect to the load from the seat surface of the toilet seat, and the strength that supports the weight of the user even if the thickness of the upper case 21 is reduced. Therefore, the thickness of the upper case 21 can be reduced, the thermal conductivity is improved, and the heating efficiency is improved, so that the energy is saved and the material cost and the weight can be easily reduced.

  In addition, since the end surface portion formed by pressing the metal plate material is also turned inside, the end surface does not corrode and does not impair the appearance or function, and there is no risk of injury by the user touching the end surface.

  Further, since the lower case 22 is configured with the rib 22f so as to receive the upper case 21, the positional deviation does not occur and the assemblability is good.

  Further, since a silicon sealant can be applied to the joining slope, water can be prevented from entering the cavity.

  Moreover, since the upper and lower fixing claws are formed at the important points along the outer peripheral edge and the inner peripheral edge, even if the toilet seat is formed of a sheet material such as a metal plate material, there is no special processing such as welding. A heated toilet seat having a hollow portion in the upper case and the lower case can be easily configured.

  As mentioned above, since the heating toilet seat concerning this invention can improve the external appearance of a junction part and can improve waterproofing performance, it can be applied also to the use of other water supply apparatus.
