DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a heating toilet seat having a heater.

[0002]

2. Description of the Related Art Conventionally, for example, as shown in FIG. 6, a heating toilet seat 100 described in Japanese Utility Model Laid-Open Publication No. Hei 6-34598.
Has a toilet seat body 111, a toilet seat lower plate 113 that is fitted into the toilet seat body 111 without any gap, and a heater 114 that is fixedly attached to the inner surface of the toilet seat body 111. Is warmed from its inner surface, thereby eliminating the resistance when a person sits on the toilet seat body 111, and at the same time, makes the sitting comfort good.

At this time, the toilet seat body 111 is directly heated by the heater 114, while the toilet seat lower plate 113 is directly placed on a toilet (not shown). There will be a temperature difference between them. Therefore, since natural convection of air is expected to occur in the internal space formed by the toilet seat body 111 and the toilet seat lower plate 113, heat transfer accompanying natural air convection, that is, from the toilet seat lower plate 113 Is concerned about heat radiation.

Therefore, in the heating toilet seat 100 of FIG. 6, a heat insulating material 116 is disposed in an internal space formed by the toilet seat body 111 and the toilet seat lower plate 113, and the temperature of the heat sink is relatively lower than that of the toilet seat body 111. For the toilet seat lower plate 113, the toilet seat body 11
1 prevents air in the internal space formed by the toilet seat lower plate 113 from coming into contact with the air. Thereby, the toilet seat lower plate 11
3, the power consumption of the heater 114 is reduced.

[0005]

However, in the heating toilet seat 100 of FIG. 6, in order to reduce heat radiation from the toilet seat lower plate 113, the inner space formed by the toilet seat body 111 and the toilet seat lower plate 113 is insulated. In this regard, in this regard, it is necessary to add an assembling process for disposing the heat insulating material 116 to the existing manufacturing process.
However, there is a problem that an increase in costs due to an increase in component costs and assembly costs cannot be avoided. That is, instead of the heat insulating structure using the heat insulating material 116 having such a problem,
There has been a demand for a new heat insulating structure that can maintain the existing manufacturing process and reduce the cost.

Accordingly, the present invention has been made to solve the above-described problems, and provides a heating toilet seat provided with a new heat insulating structure which maintains the existing manufacturing process and reduces the cost. That is the task.

[0007]

Means for Solving the Problems According to a first aspect of the present invention, there is provided a toilet seat body, and a toilet seat lower plate which is fitted into the toilet seat body to form an internal space. In a heating toilet seat having a heater fixed to an inner surface of the toilet seat body, a stagnation area where a part of the air in the internal space stays is reduced by using a shape of an inner surface of the toilet seat lower plate. It is provided on the entire inner surface of the plate.

According to a second aspect of the present invention, in the heating toilet seat according to the first aspect, the shape of the inner surface of the lower plate of the toilet seat is formed by a projecting plate protruding from the inner surface of the lower plate of the toilet seat. , Is characterized. According to a third aspect of the present invention, in the heating toilet seat according to the second aspect, the protruding plate has a lattice shape.

In the heating toilet seat according to the present invention having such features, a feeling of resistance when a person sits on the toilet seat body is eliminated, and at the same time,
In order to improve the sitting comfort, the toilet seat body is heated from its inner surface by a heater. However, since the toilet seat body is directly heated by the heater, a temperature difference occurs between the toilet seat body and the toilet seat lower plate. Therefore, natural convection of air is generated in the internal space formed by the toilet seat body and the toilet seat lower plate.

[0010] However, in the heating toilet seat of the present invention, a stagnation area in the internal space where a part of the air in the internal space stays,
It is provided on the entire inner surface of the toilet seat lower plate. Therefore, even if natural convection of air occurs in the internal space, the natural convection of air is blocked by the stagnation area provided on the entire inner surface of the toilet seat lower plate, and the toilet seat having a relatively lower temperature than the toilet seat body. Inability to contact the inside surface of the lower plate. Thus, heat dissipation from the toilet seat lower plate can be suppressed, and power consumption of the heater can be reduced.

Further, since the stay area provided on the entire inner surface of the toilet seat lower plate utilizes the shape of the inner surface of the lower toilet seat plate, a new stay area is provided to provide the entire inner surface of the toilet seat lower plate. It is not necessary to add an additional process to the existing manufacturing process, and there is no material cost or assembly cost, so that there is almost no increase in cost.

That is, in the heating toilet seat of the present invention, in the internal space formed by the toilet seat body and the toilet seat lower plate, a stagnation region where a part of the air in the internal space stays is provided on the entire inner surface of the toilet seat lower plate. It has a new heat insulation structure that can suppress the heat radiation from the toilet seat lower plate and reduce the power consumption of the heater. This new heat insulation structure uses the shape of the inner surface of the toilet seat lower plate to stay. Because it depends on the area, there is no need to add a new process to the existing manufacturing process.Also, there is no cost for materials and assembly, and there is almost no increase in cost. Cost increase can be further reduced.

In the case where the shape of the inner surface of the lower seat plate is formed by a protruding plate protruding from the inner surface of the lower seat plate, the protruding plate protruding from the inner surface of the lower seat plate is used as a retention area. In addition to this, it also serves as a reinforcing rib for the toilet seat lower plate, so that the toilet seat lower plate can be made thinner.

Further, in the case where the shape of the inner surface of the lower toilet seat is formed by a lattice-shaped protruding plate, a part of the air in the inner space is used as a stagnation area utilizing the shape of the inner surface of the lower toilet seat. Since the stopping operation can be significantly exhibited, the power consumption of the heater can be further reduced.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a sectional view of a heating toilet seat 1 according to the present embodiment. As shown in FIG. 1, the heating toilet seat 1 of the present embodiment includes a toilet seat body 11, a toilet seat lower plate 13, a heater 1
4, aluminum foil 15 and the like.

The toilet seat body 11 is formed by injection molding using polypropylene (PP) as a raw material.
Its thickness is about 3.5 to 7.0 mm. At this time,
A recess for fitting the toilet seat lower plate 13 is also formed in the peripheral portion of the toilet seat body 11. Then, on the inner surface of the toilet seat 11, the heater 14 is attached in a fixed state, and is covered with the aluminum foil 15. The heater 14 has a power consumption of 5
It has a temperature of about 0 W and an operating temperature of about 47 ° C., and is arranged as shown in the front view of the toilet seat body 11 in FIG. still,
The sectional view of the heating toilet seat 1 in FIG. 1 is taken along the line AA in FIG. In FIG. 1, the width of the cross section of the heating toilet seat 1 is about 100 mm, and its height is about 45 mm.

The toilet seat lower plate 13 is made of polypropylene (PP).
Is used as a raw material to be formed by injection molding, and has a thickness of about 5.0 mm. At this time, a convex portion for fitting with the toilet seat body 11 is also formed on the peripheral portion of the inner surface of the toilet seat lower plate 13. Further, on the inner surface of the toilet seat lower plate 13, as shown in the perspective view of the toilet seat lower plate 13, a grid-like projecting plate 16 is provided with a thickness of about 1 mm over the entire area of the above-mentioned peripheral ridge. Molded. The lattice of the protruding plate 16 is a regular square of about 20 mm, and the depth thereof is about 5 to 7 mm.

Therefore, when the heating toilet seat 1 according to the present embodiment is assembled by fitting the concave portion of the peripheral portion of the toilet seat body 11 and the convex portion of the peripheral portion of the inner surface of the toilet seat lower plate 13 into each other, An internal space 12 is formed between the toilet seat lower plate 13 and the toilet seat lower plate 13 as shown in FIG. When the heater 14 is energized, the toilet seat 11 is
Can be heated from the inner surface of the toilet seat 1
1 can eliminate the feeling of resistance when a person sits down, and at the same time, can improve the sitting comfort.

Since the toilet seat 11 is directly heated by the heater 14, a temperature difference occurs between the toilet seat 11 and the toilet seat lower plate 13. Therefore, in the internal space 12 formed by the toilet seat body 11 and the toilet seat lower plate 13, for example, natural convection of air occurs as shown by a two-dot chain line in FIG.

However, in the heating toilet seat 1 of the present embodiment, since the lattice-shaped projecting plate 16 is located below the internal space 12, the natural convection of the air is reduced by the lattice-shaped projecting plate 16.
Flowing over At this time, since a part of the air in the internal space 12 stays in the lattice-shaped protruding plate 16, that is, the stagnation area in the internal space 12 where a part of the air in the internal space 12 stays is placed in the toilet seat. It can be said that it is provided on the entire inner surface of the toilet seat lower plate 13 by using the grid-like projection plate 16 protruding from the inner surface of the lower plate 13.

Therefore, in the internal space 12, for example,
As shown by the two-dot chain line in FIG. 1, even when natural convection of air occurs, natural convection of air is blocked by a stagnation area provided on the entire inner surface of the lower toilet seat 13 and used as a stagnation area. Even if it is possible to contact the tip portion of the grid-shaped protruding plate 16, it cannot contact the inner surface of the toilet seat lower plate 13 having a relatively lower temperature than the toilet seat body 11. Thus, heat dissipation from the toilet seat lower plate 13 can be suppressed, and power consumption of the heater 14 can be reduced.

The stagnation area provided on the entire inner surface of the toilet seat lower plate 13 utilizes the grid-like projecting plate 16 protruding from the inner surface of the toilet seat lower plate 13. It is not necessary to add a new process to an existing manufacturing process in order to provide a stagnation area on the entire surface. However,
In order to protrude the grid-shaped protruding plate 16 from the inner surface of the toilet seat lower plate 13, it is necessary to repair the mold used for injection molding, but the burden is reduced by the number of heating toilet seats 1 produced. Further, since there is no cost for parts and assembly, there is almost no increase in cost.

That is, in the heating toilet seat 1 of the present embodiment, in the internal space 12 formed by the toilet seat body 11 and the toilet seat lower plate 13, the stagnation area where a part of the air in the internal space 12 stays is replaced by the toilet seat lower plate. 13 has a new heat insulating structure capable of suppressing heat radiation from the toilet seat lower plate 13 and reducing power consumption of the heater 14 by being provided on the entire inner surface of the toilet seat 13. Since it is based on the stagnation area using the shape of the inner surface of the plate 13 (the lattice-shaped protruding plate 16 protruding from the inner surface of the lower toilet seat plate 13), it is not necessary to add a new process to the existing manufacturing process. In addition, since there is no member cost or assembly cost, and there is almost no cost increase, it is possible to maintain the existing manufacturing process and reduce the cost increase.

The shape of the inner surface of the toilet seat lower plate 13 is
The protruding plate 16 protruding from the inner surface of the lower toilet seat 13 is not only used as a stagnation area but also reinforcing the lower seat 13 of the toilet seat. Since it also serves as a rib, the thickness of the toilet seat lower plate 13 can be reduced.

It should be noted that the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention. For example, in the heating toilet seat 1 of the present embodiment,
Although the shape of the inner surface of the toilet seat lower plate 13 is formed by a grid-like projecting plate 16, as shown in FIGS. 4 and 5, the projecting plate 16 protruding from the inner surface of the toilet seat lower plate 13 is provided in parallel. You may.

However, as compared with the protruding plate 16 shown in FIGS. 4 and 5, the grid-shaped protruding plate 16 shown in FIG.
As a stagnation area utilizing the shape of the inner surface of the toilet seat lower plate 13, it is possible to remarkably exhibit a part of the air in the internal space 12, so that the power consumption of the heater 14 can be further reduced.
