Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heated toilet seat which has a heater disposed within the toilet seat body and which collects heat from the surface of the toilet seat when the user is sitting on it.
The present invention provides an effective method for detecting the temperature of a heated toilet seat.

Conventional technology Generally, in order to attach a temperature detection means to a heated toilet seat, the eighth
As shown in FIG. 9 and its cross-sectional view, a temperature detection means 4 is placed between a string heater 3 disposed on the inner surface 2 of the toilet seat body 1.
between the temperature detection means 4, the assembled heater 3, and the inner surface 2 of the toilet seat main body.
is filled and pressed against the inner surface 2 of the toilet seat main body by the elasticity of the holding plate 6. (Japanese Utility Model Publication No. 56-166898) The holding plate 6 has a mounting hole 4 at 4, into which the hose 7 protruding from the inner surface 2 of the toilet seat body is inserted, and the holding plate 6 is held down by the mounting hole 1.
In this state, the tip of the hoss 7 is welded to fix the presser plate 6.

Problems to be Solved by the Invention However, in mounting the temperature detecting means 4 as described above, the presser plate 6 is fixed only by one post 7 and 0 is fixed only by the heat welded part 8. Due to its structure, the thermally welded part 8 receives the reaction force when the temperature detection means 4 is elastically pressed, and the load when the user sits on the toilet seat body 1. When the toilet seat was placed on the toilet bowl ()'L, the impact caused large stress and vibration, which caused the heat welded part 8 to fly off and the presser plate 6 to come off. If the presser plate 6 comes off, the temperature detection means 4 will be fixed only with the filler material 5, but the filler material 5 is made with emphasis on thermal conductivity, and is generally made of a silicone com or the like. Although it is used and cannot withstand the stress and vibrations mentioned above, it peels off from the inner surface 2 of the toilet seat body and the string heater 3.
Temperature detection means 4 is located inside the toilet seat body [ti2 or string heater 3].
This results in a separation from the In that case, the temperature detection means 4 cannot detect an appropriate temperature, and the string heater 3
As a result, the temperature of the toilet seat body 1 rose excessively, posing a risk of burns to the user.

Furthermore, in the conventional example, since there is no positioning means for the temperature detection means 4, r! If the degree detection means 4 slides in the longitudinal direction of the string heater 3 or is placed on the string heater 3, the assembly workability is poor because the degree detection means 4 may slide in the longitudinal direction of the string heater 3 or be placed on the string heater 3, resulting in poor assembly workability. Met. Therefore, the surface temperature of the toilet seat body varies widely among products, which poses a problem in terms of quality assurance.

The present invention solves these conventional problems, and provides a heated toilet seat in which the temperature detection means is reliably fixed to the toilet seat body, and the surface temperature has less variation.

Means for Solving the Problems In the heated toilet seat of the present invention, the temperature detection means includes a temperature detection element, a heat-sensitive plate, and a lead portion, and the heat-sensitive plate and the lead portion are attached to separate first and second fixing means. This ensures that it is securely fixed to the toilet seat body.

Function: In the heated toilet seat of the present invention, since the heat-sensitive plate of the temperature detection means is securely fixed to the toilet seat body, the temperature detection element and the toilet seat body are thermally closely connected via the heat-sensitive plate, and the temperature of the toilet seat body can be measured. In addition to being able to detect the temperature appropriately, it is fixed in two places: the heat-sensitive plate of the temperature detection means and the lead part, so positioning is easy and assembly workability is good, and stable production of heated toilet seats from a quality assurance perspective. becomes possible.

EXAMPLE Hereinafter, a heated toilet seat according to an example of the present invention will be described with reference to the drawings. 3 is an external perspective view of a heated toilet seat according to an embodiment of the present invention attached to the toilet bowl 9, and FIG. 4 is a schematic cross-sectional view m1 seen from the back side of the heated toilet seat of FIG. 3. 10 is a toilet pig, and 11 is a toilet seat main body in which a heater assembly 12 is disposed over almost the entire inner surface of the seat 1ni.

13 is a case body, and the toilet lid 10 and the toilet seat body 11 are rotatably fixed to the case body 13 by a pair of left and right rotations 11i11114.14'. The user rotates the toilet hook 10 when using it for excretion, stands it up, sits on the toilet seat body 11, and collects the heat from the string heater 12 from the toilet seat body 110. Inside the case body 13, a control circuit 15 for controlling the energization of the heater assembly 12 and a volume 17 linked to a temperature control knob 16 are provided. is connected and power is supplied.

Inside the toilet seat body 11, a string heater 12, a body safety device 19 connected in series to the string heater 12, and a temperature detection means 20 for detecting the temperature of the toilet seat body 11 are provided. and are connected to the control circuit 15, respectively. 22 is a couminal stand that connects the connection cord 21 and the control circuit 15.

As shown in FIG. 5 as a plan view and as shown in FIG. , a metal heat-sensitive plate 25 for increasing the thermal sensitivity of the temperature-sensing element 23, and a molding 26 made of epoxy to waterproof the connection between the temperature-sensing element 23 and the lead portion.Thermal plate 25, the lead part 24 is connected to the engaging part 2;
7, and the other end has a mounting part 2 with a round hole 28.
There are 9 and ti-C. The heat sensitive plate 25 has a temperature detection element 23
It is bent into a U-shape around the circumference, and the bottom facets 1 and 1130 are horizontal and f-knee. Further, from the mounting surface 3o toward the mounting portion 29, it is bent slightly downward in a dogleg shape.

FIG. 7 is a circuit diagram showing connections of each component.

The volume 17 is set by the temperature control knob 16 according to the user's preference. The volume setting value and
The detected value from the temperature detection means 2o attached to the toilet seat body 11 is compared by the control circuit 15, and the energization of the string heaters 12 is controlled so that the detected value approaches the set value.

The protector 19 is activated when the temperature of the toilet seat body rises above a set value due to an abnormality in the volume 17, the temperature detection means 20, or the control circuit 15, and prevents the temperature of the toilet seat body from rising excessively.

In order to maintain the surface temperature of the toilet seat body 11 at the temperature set on the adjustment knob 16 even if the room temperature fluctuates, the temperature detection means 2 is used.
0 must detect the temperature of the toilet seat body 11, not the temperature of the string heater 12. Therefore, the method of mounting the temperature detection means 20 determines the temperature performance of the heated toilet seat.

ri) Figure 1 is l1lli +! 11 is an enlarged plan view showing the part where the detection means 20 is taken, and FIG. A hoss (first fixing means) 3 is located approximately in the center of the string heater 12, is arranged substantially parallel to the string heater 12, and protrudes from the inner surface 31 of the toilet seat body 11.

When the temperature detection means comes into contact with the string heater 12, it is controlled to keep the heater temperature constant, so the surface temperature of the toilet seat body 11 will fluctuate due to changes in the room temperature. Therefore, in order to keep the surface temperature of the toilet seat body constant regardless of changes in the room temperature, the temperature detection means must be fixed so as to detect the temperature of the toilet seat body 11.

As mentioned above, the temperature detection means of this heated toilet seat is fixed to the inner surface of the toilet seat body at two places, the mounting part 29 of the heat-sensitive plate and the lead part. It will not come off even if it is subjected to stress or vibration due to opening/closing impact.

Further, positioning of the temperature detecting means during installation is easy, workability is good, and there is no possibility of displacement during installation.

The heat-sensitive plate 25 is firmly in contact with the inner surface of the toilet seat body, and is fixed to a boss 32 protruding from the inner surface of the toilet seat body, thereby thermally and tightly connecting the toilet seat body and the temperature detection element 23. . Therefore, the temperature detection means can accurately detect the temperature of the toilet seat body, and even if the room temperature changes, the temperature of the toilet seat body can be set (or maintained immediately).

In order to increase the temperature detection sensitivity, if a thermally conductive filler material such as a resin made by NRICON is applied between or around the heat sensitive plate 25 and the toilet seat body, the effects 71' and a will be further enhanced.

Effects of the Invention As described above, in the heated toilet seat of the present invention, since the temperature detection means is fixed at two places, the heat sensitive plate and the lead part, it will not come off even if stress or vibration is applied due to load or impact. do not have.

Further, the temperature of the toilet seat body is sensitively transmitted to the temperature detection element by the heat sensitive plate, and the temperature detection means can accurately detect the temperature of the toilet seat body. Therefore, the surface temperature performance of the heated toilet seat is less affected by room temperature.

In addition, it is easy to position the 78A pest detection means (mold).
The assembly workability is good, and there is little discomfort during installation. This makes it possible to produce heated toilet seats with little temperature variation between products, which is extremely advantageous in practical terms.
