Description

  The present invention relates to a heated toilet seat device attached to a western-style toilet.

  Although the toilet seat which comprises a heating toilet seat apparatus is heated by the electric heat, the request | requirement of energy saving is increasing in recent years. As a measure to save energy in the heating toilet seat device, it is effective to suppress heat dissipation from the toilet seat, so heat insulation from the toilet seat to the atmosphere is suppressed by incorporating a heat insulating material in the toilet lid that covers the toilet seat. A technique has been proposed (see, for example, Patent Document 1). The heating toilet seat device described in Patent Document 1 has a structure in which a heat insulating material is built in a hollow toilet lid.

Japanese Patent Laid-Open No. 2000-126087

  As in the heating toilet seat device described in Patent Document 1, it is extremely difficult to manufacture a heat insulating material inside a hollow toilet lid, and therefore a structure in which a heat insulating material is provided between the toilet lid and the bottom plate. Is adopted. However, when the toilet lid and the bottom plate are separated, there is a gap between these members due to manufacturing dimensional tolerances. When the toilet lid is washed with water, water and detergent are removed from these gaps. May enter and stay inside the toilet lid. And water, detergent, etc. which stayed in the toilet lid may change in quality with the passage of time and generate a strange odor or bad odor.

  The problem to be solved by the present invention is to provide a heated toilet seat device in which water or detergent that has entered the toilet lid does not stay after the toilet lid is washed with water.

The heating toilet seat device of the present invention,
A toilet seat having a heating source, a toilet lid in which a heat insulating material is disposed in a hollow space formed by a toilet lid body and a toilet lid bottom plate, and a casing that rotatably supports the toilet seat and a base end portion of the toilet lid. And a heating toilet seat device having a gap communicating the hollow space and the outside of the toilet lid,
At least one of the surface of the heat insulating material, the inner surface of the toilet lid main body and / or the inner surface of the toilet lid bottom plate is provided with a recess communicating with the gap, and the surface of the heat insulating material and the toilet lid are formed by the recess. A gap is formed between the main body and / or the toilet lid bottom plate.

  With such a configuration, the recess that communicates with the gap that communicates between the hollow space formed by the toilet lid main body and the toilet lid bottom plate and the outside of the toilet lid is a discharge path for water that has entered the toilet lid. As a result, the water does not easily stay inside the toilet lid, so that the drainage of the toilet lid after washing with water becomes good. In addition, it is possible to prevent the generation of a strange odor due to the alteration of the water retained in the toilet lid.

  Moreover, it is desirable to provide a water receiving part for receiving moisture discharged from the base end part of the toilet lid that is opened in an upright state on the upper surface of the casing. With such a configuration, the water discharged from the toilet lid that has been opened in an upright state and dropped onto the upper surface of the casing is discharged through the water receiving portion, so that the seating surface of the toilet seat is moved by the water discharged from the toilet lid. It won't get wet.

  Furthermore, the concave portion is a plurality of concave grooves formed from the distal end portion to the proximal end portion of the toilet lid main body, and the projecting portions formed between the concave grooves are compressed so as to be compressed. It is desirable to hold the heat insulating material in the hollow space. With such a configuration, when the toilet lid is assembled, the protruding portion is compressed so that the heat insulating material in the hollow space is held so as not to rattle. Can be eliminated and comfort is improved.

  According to the present invention, when the toilet lid is washed with water, a heated toilet seat device that does not retain water, detergent, or the like that has entered therein can be provided.

It is a perspective view which shows the heating toilet seat apparatus which is embodiment of this invention. It is a bottom view of the toilet lid which comprises the heating toilet seat apparatus shown in FIG. It is a disassembled perspective view of the toilet lid shown in FIG. It is the sectional view on the AA line in FIG. It is the BB sectional view taken on the line in FIG. It is a top view of the heat insulating material shown in FIG. It is CC sectional view taken on the line in FIG. FIG. 2 is a partially omitted vertical sectional view of the heating toilet seat device shown in FIG. 1.

  As shown in FIG. 1 and FIG. 2, the heating toilet seat device 10 of the present embodiment is arranged around a casing 10b that forms an outer shape of a main body portion 10a installed on the upper surface of a rear portion of a western-style toilet (not shown), and is connected to the casing 10b. A toilet seat 11 and a toilet lid 12 that are movably held are provided. Inside the toilet seat 11, a heating source (not shown) for heating the toilet seat is provided. The base end portions of the toilet seat 11 and the toilet lid 12 are rotatably supported by the casing 10b via a hinge portion 13h. FIG. 1 shows a state in which the toilet lid 12 stands up and the user can sit on the toilet seat 12, but when the toilet lid 12 falls down, the toilet seat 11 is covered with the toilet lid 12.

  As shown in FIG. 3, the toilet lid 12 includes a toilet lid main body 13, a heat insulating material 14 disposed on the back side of the toilet lid main body 13, and a bottom plate 15 that covers the heat insulating material 14. As shown in FIG. 2, when the toilet lid 12 is in an assembled state, the heat insulating material 14 is sandwiched between the toilet lid main body 13 and the bottom plate 15 as shown in FIG. 8. Hinge portions 13h are provided at the left and right proximal end portions 13c of the toilet lid body 13, and as shown in FIG. 1, these hinge portions 13h are rotatably supported on the left and right side portions of the casing 10b.

  As shown in FIGS. 1 to 3, the bottom plate 15 has an opening 17 into which a hollow protrusion 16 protruding from the back surface of the toilet lid body 13 is detachably fitted, and a second hollow protrusion 26. An engaging portion 25 that is detachably engaged is provided. As shown in FIG. 5, in the engaging portion between the second hollow protrusion 26 and the locking portion 25, the second hook 25 a of the locking portion 25 fitted into the second hollow protrusion 26 is the first. The two hollow protrusions 26 are engaged with the holes 26a from the inside.

  A toilet seat cushion 18 is detachably mounted from the lower surface side of the bottom plate 15 to the open end 16b of the hollow protrusion 16 fitted to the opening 17 of the bottom plate 15. In other words, the toilet seat cushion 18 is attached to the opening end 16 b that is positioned substantially on the same plane as the opening 17 of the bottom plate 15. The toilet seat cushion 18 is formed of a synthetic resin-based elastic material, and includes a lid portion 18b having a diameter larger than that of the opening end 16b, and a plurality of leg portions 18a protruding from the back surface of the lid portion 18b. A plurality of flanges 18c for preventing separation are formed on the outer periphery of 18a.

  If the leg portion 18a of the toilet seat cushion 18 is inserted into the hollow protrusion 16 from the opening end 16b and the back surface of the lid portion 18b is brought into close contact with the periphery of the opening end 16b, the region around the opening portion 17 on the bottom surface of the bottom plate 15 becomes the toilet seat cushion. 18, the bottom plate 15 having the hollow protrusion 16 fitted into the opening 17 is restrained by the toilet lid cushion 18.

  As shown in FIGS. 4 to 7, a heat insulating material 14 is disposed in the hollow space R formed by the toilet lid main body 13 and the toilet lid bottom plate 15, and the inner surface of the peripheral wall portion 13 b of the toilet lid main body 13 and the outer periphery of the bottom plate 15. Between the part 15f, a minute gap S that communicates the hollow space R and the outside (in the atmosphere) of the toilet lid 12 is provided. The gap S is provided in order to cope with a dimensional tolerance between the toilet lid main body 13 and the toilet lid bottom plate 15.

  Also, as shown in FIGS. 6 and 7, by providing a plurality of concave grooves 14 f that are concave portions communicating with the gap S on the surface of the heat insulating material 14, the surface of the heat insulating material 14 and the toilet lid main body 13 are provided. A gap U (see FIG. 5) is formed, and protrusions 14e are formed between the plurality of concave grooves 14f. These concave grooves 14f are formed linearly from the distal end portion of the toilet lid main body 13 toward the proximal end portion. Although the depth dimension of the concave groove 14f is not limited, in this embodiment, the depth dimension is set larger than the dimension of the gap S between the toilet lid body 13 and the toilet lid bottom plate 15. As shown in FIG. 6, a drainage cutout 14g is formed on the distal end side of the concave groove 14f (the distal end side of the toilet lid 12).

  In the heating toilet seat device 10 of the present embodiment, the toilet lid body 13 and the bottom plate 15 are made of polypropylene, whereas the heat insulating material 14 is made of foamed resin (foamed polystyrene), and the heat insulating material 14 is made of the toilet lid main body 13. And a size slightly larger than the hollow space R formed by the bottom plate 15. When the toilet lid 12 is assembled, the toilet lid main body 13 and the bottom plate 15 are joined in a state where the protruding portion 14 e described above is compressed and deformed between the toilet lid main body 13 and the bottom plate 15.

  Thus, since the heat insulating material 14 is hold | maintained in the hollow space R so that the protrusion part 14e formed between the several ditch | grooves 14f may be compressed with the toilet lid main body 13 and the baseplate 15, the toilet lid The heat insulating material 14 can be fixed in the twelve hollow spaces R without rattling. In addition, since a plurality of these protrusions 14e are provided, they do not dent even when a load is applied to the surface of the toilet lid 12, and no abnormal noise is generated when the toilet lid 12 is opened or closed. .

  When the toilet lid 12 is washed, the toilet lid 12 removed from the casing 10b is often washed with water or with water. In this case, since water may enter from the gap S between the toilet lid body 13 and the bottom plate 15 and reach the hollow space R in which the heat insulating material 14 is disposed, the toilet lid 12 is shaken after being washed. It is necessary to discharge water. Therefore, as in the case of the heating toilet seat device 10, if a plurality of concave grooves 14f are provided on the surface of the heat insulating material 14 from the front end side to the base end side of the toilet lid 12, the water that has entered the toilet lid 12 can be removed. Since the water is quickly discharged from the gap S through the concave groove 14f, water drainage is improved. At that time, the notch 14g serves to drain water when draining water from the base end of the toilet lid 12, and when noting water from the distal end of the toilet lid 12, air is supplied to the concave groove 14f. It plays the role of air holes to be introduced.

  In addition, conventionally, if water is not completely drained from the toilet lid immediately after being washed, and is attached to the casing of the heated toilet seat device as it is, from the place where the toilet lid is washed to the toilet where the heated toilet seat device is arranged While the toilet lid was carried, water droplets could fall and wet the movement path (for example, a corridor). However, the heating toilet seat device 10 has a drain groove 14e on the surface of the heat insulating material 14 inside the toilet lid 12. Such a fear is eliminated because the water supply is improved.

  On the other hand, as shown in FIG. 8, a water receiving portion 10 c that receives moisture discharged from the proximal end portion of the toilet lid 12 that is opened in an upright state is provided on the upper surface of the casing 10 b. Therefore, even if water remains in the toilet lid 12, if the toilet lid 10b is opened (standing position) after the toilet lid 12 is attached to the casing 10b, the proximal end portion of the toilet lid 12 is Since it is located on the upper surface of the casing 10b, the water discharged from the base end portion of the toilet lid 12 by gravity falls into the water receiving portion 10c and travels from the upper surface of the casing 10b to the front inclined surface 10d of the western-style toilet (not shown). Flow down on the rim. For this reason, the water discharged from the toilet lid 12 does not touch the toilet seat 11 or fall on the seating portion of the toilet seat 12. Therefore, the water that has fallen from the toilet lid 12 does not get wet on the seating surface of the toilet seat 11, and it is possible to sit comfortably at any time.

  Thus, in the heating toilet seat device 10, the concave groove 14f that communicates with the gap S that communicates the hollow space R formed by the toilet lid body 13 and the toilet lid bottom plate 15 and the toilet lid exterior (in the atmosphere), By functioning as a drainage path for the water that has entered the toilet lid 12, it becomes difficult for water to stay inside the toilet lid 12, so that the toilet lid 12 is well drained after being washed with water. In addition, it is possible to prevent the generation of a strange odor due to the alteration of the water retained in the toilet lid 12.

  In addition, since the heating toilet seat apparatus of this invention is not limited to the heating toilet seat apparatus 10 of embodiment shown in FIGS. 1-8, it replaces with the structure which provided the groove 14f on the surface of the heat insulating material 14, and toilet The lid body 13 or the bottom plate 15 may have a recess or a groove. Further, instead of providing the concave grooves 14f sandwiched between the plurality of protrusions 14e formed in parallel to the surface of the heat insulating material 14, a plurality of protrusions may be interspersed.

  The heated toilet seat device of the present invention can be widely used by being attached to various types of Western-style toilets installed in toilets such as ordinary houses, public facilities, and accommodation facilities.
