BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing freezing of a water reservoir in a flush toilet.

[0002]

2. Description of the Related Art Conventionally, as a freeze prevention device for a flush toilet, a heater formed in a shape close to the developed shape of the back surface of the water storage portion of the toilet, such as that disclosed in Japanese Utility Model Laid-Open Publication No. 3-62172, is used. The type that directly heats the pottery surface with a heater by directly pasting it on the pottery surface of
As disclosed in Japanese Patent No. 3586, a plate-like heat insulating material punched and formed according to the shape of the opening is fitted to the lower end of a skirt portion formed around the sewage portion around the toilet body. There is a type in which a heater is arranged above and a space surrounded by the above-mentioned hakama part and heat insulating material is heated by the heater.

[0003]

[Problems to be Solved by the Invention] However, in the former method, after a heater is first attached to a ceramic surface, it must be held down with a heat insulating material, and the periphery of the heat insulating material must be further sealed. However, it is troublesome and workability is poor. In addition, it is difficult to reliably hold the entire surface of the heater with heat insulating material due to the complicated shape of the back surface of the reservoir, and a space is easily formed between the heater and the heat insulating material. The heater may peel off from the surface of the porcelain due to aging or the like, and the temperature of the heater in the peeled part may be excessively increased, causing an excessive load on the heater and causing a failure.

On the other hand, in the latter, not only the capacity of the heater is increased due to the large space heated by the heater surrounded by the skirt and the heat insulating material, but also the inner peripheral surface of the skirt is covered with a heat insulating material. This type is not good in workability because it must be insulated and requires work for that.

[0005] The present invention has been made in view of the above-mentioned problems of the prior art, and its purpose is to make it easy to assemble into a toilet bowl without fear of falling off of the heater.
An object of the present invention is to provide a toilet bowl freezing prevention device that requires a small heater capacity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, A is a flush toilet, 1 is a ball portion thereof, and 2 is a drainage channel. In this embodiment, the drainage channel 2 is provided along the back of the ball portion 1 from an entrance 21 opened at the bottom of the ball portion 1. After extending obliquely upward, make a U-turn, hang down substantially vertically downward, and reach an outlet (not shown). The lower portion of the ball portion 1 and the portion from the entrance 21 of the drainage channel 2 to the U-turn portion 22 This forms a reservoir 3. Further, the toilet A has a hakama portion 4 formed substantially all around the water storage portion 3, and a freezing prevention device for preventing the water storage portion 3 from freezing in a space 5 surrounded by the water hammer portion 4. Apparatus B is deployed.

The anti-freezing device B comprises a wrapping member 6 disposed in the space 5 and constituting a closed space 51 surrounding the water storage section 3, and a heater 7 for heating the closed space 51.
The wrapping member 6 is a molded product of a heat insulating material, for example, a synthetic resin such as foamed polyurethane, and has a flat shape having substantially the same contour and size as the contour of the space portion 5 at a position as high as possible of the toilet skirt portion 4, 3 has a concave portion 61 having a shape substantially similar to the back surface shape, and is fitted into the space 5 so that the peripheral edge portion abuts against the inner surface of the skirt portion 4 and is adhesively sealed to the portion. 3 is covered so as to enclose the entire rear surface thereof, and a narrow sealed space 51 is formed between the upper surface thereof and the rear side surface of the water storage section 3. That is, in this embodiment,
The wrapping member 6 has a concave portion 61 wrapping the back surface of the water reservoir 3.
To form a narrow enclosed space 51 with the entire back surface.
The surrounding portion other than the back surface of the reservoir 3
A contact portion that abuts the portion.

Further, the wrapping peripheral portion upper surface to a predetermined height to member 6, the encasement member in a state where the encasement member 6 is disposed at a predetermined position of the space portion 5 specifically
Projection 8 of height corresponding to the distance to be formed is formed to project at predetermined intervals between 6 and accumulated water portion 3 back surface, follicle
When the stuffing member 6 is fitted into the space portion 5 , the projection 8 comes into contact with the inner wall surface of the toilet on the back side of the water storage portion , and the wrapping member 6
A predetermined closed space 51 can be ensured between the water reservoir 3 and the back surface.

Meanwhile, the heater 7 is mounted deployed in the recess 61 portion inner surface of the pre-encasement member 6 as shown in FIGS. 3 to 4, it is integrally formed with the encasement member 6, wrapped
Since the member 6 is attached at a predetermined position in the space 5 on the back side of the water storage section 3 of the toilet A, a constant interval is maintained between the member 6 and the rear surface of the water storage section 3.

The heater 7 is a belt-like or wrapping part.
A surface heater, a cord-shaped heater, a ceramic heater, or the like formed in the unfolded shape of the concave portion 61 of the material 6 and wrapped along the inner surface of the concave portion 61 as shown in FIGS.
5 is placed on the enclosing member 6 and fixed to the enclosing member 6 with an appropriate adhesive, a double-sided adhesive tape, or the like.
As shown in FIG. 7, a recess 62 for mounting a heater is provided on the surface of the recess 61 of the wrapping member 6, and the heater 7 is fitted in the recess 62, and a double-sided adhesive tape or an appropriate pressing member is used. And is fixed in the recess 62. Although not shown, a suitable heat-resistant material is interposed between the heater 7 and the wrapping member 6.

[0013] wrapping as shown in FIGS. 5 and 7 member 6
If the heater 7 is provided in the recess 62 so that the heater 7 is accommodated in the recess 62, the positioning when the heater 7 is mounted can be performed accurately, and the heater 7 is hardly detached. Especially when the heater 7 is code heater, but is arranged to decide the pattern as shown in FIG. 6, is simple even heater 7 is installed be determined the pattern encasement member 6 side, encasement member 6 and the pattern is Since it is more efficient than combining drawn heaters, the wrapping member 6
It is convenient to form the heater mounting recess 62 in the required pattern in advance and to arrange the heater 7 in the recess 62 in a fitted state.

The heater 7 does not necessarily need to be provided down to the lower position in the concave portion 61. For example, as shown in FIG. 8, the water reservoir 3 is located only near the reservoir surface of the toilet A which is most susceptible to outside air. Can be arranged in a belt shape so as to surround in the lateral direction.

Further, the heater 7 has a temperature controller 9 integrally provided at an appropriate position, and a sensor portion 91 of the heater 7 contacts the back surface of the water storage section 3 in the vicinity of the water storage surface, for example, in a portion within about 30 mm from the water storage surface. doing. The area of about 30 mm from the pool surface is the area most susceptible to outside air, and since freezing starts from the periphery of the flowing water surface, detecting the temperature of this part and controlling the temperature ensures that freezing is prevented. It is possible to do.

Although not shown, it is needless to say that a cord is connected to the heater 7 , and the cord is drawn out from an appropriate portion of the skirt 4.

In the embodiment described above, the positioning projection 8 is provided on the upper surface of the peripheral portion of the wrapping member 6, but FIGS.
It is also optional to provide the projection 8 on the inner surface of the concave portion 61 of the enclosing member 6 as shown in FIG. In this case, when the heater 7 is a surface heater, a hole 10 as shown in FIG. For the above positioning
The projection 8 may be provided on the inner wall surface of the toilet on the back side of the reservoir section 3 ,
It is also possible to provide both on the wrapping member 6 side and on the inner wall surface of the toilet on the back side of the reservoir section 3 .

[0018]

[Effect] Since the present invention is configured as described above, the following effects can be obtained. (1) A heater is disposed on a wrapping member made of a heat insulating material, and an integrated heater is fitted into a space behind the water reservoir of the toilet, and its abutting portion is other than the rear surface of the water reservoir of the toilet. By contacting the wrapping member, the wrapping member covers the back side of the water reservoir of the toilet so as to wrap the back side of the water reservoir, and a narrow sealed space is formed between the wrapping member and the back side of the water reservoir. The space can be heated by a heater to prevent freezing of the water storage portion, and since the closed space is narrow, a heater having a small capacity may be used as a heater for warming this space. Also wrap
Fitted only member to accumulated water unit back side of the space of the toilet, the person
The contact part should be in contact with the rest
Since the assembly is completed by sealing with the adhesive,
Assembly work is easy and workability is greatly improved. (2) Since the heater is disposed integrally with the wrapping member on the upper surface of the wrapping member, there is no danger of falling off. Therefore, as in the conventional type in which the heater is directly attached to the backside of the basin of the toilet bowl, There is no inconvenience that the heater temperature rises excessively due to the peeling of the heater and shortens the life of the heater. (3) Positioning projections are provided on at least one of the wrapping member and the inner wall surface on the back side of the toilet section of the toilet, so that in assembly, the projections come into contact with the other party and are located between the wrapping member and the bottom of the reservoir section. A predetermined space can be reliably secured, and assembly is facilitated. In addition, since a predetermined space is reliably secured between the wrapping member and the back surface of the water storage section as described above, the closed space becomes too large because the wrapping member is not sufficiently pushed into the space behind the water storage section. The capacity of the heater is insufficient and the wrapping member is pushed too much and the heater comes into contact with the ceramic surface, and the heat of the heater is taken away by the ceramic and the amount of heat required to heat the enclosed space is insufficient There is no danger of such inconvenience.
