Problems to be solved by the invention
However, in the above-described heating toilet, since the heating element unit is folded back, the heaters may be close to each other in the folded-back portion. In this case, the portions where the heaters are close to each other generate heat excessively, and the heat is excessively transmitted to the excessive temperature rise prevention device, causing the excessive temperature rise prevention device to cut off the energization to the heat generating body unit.
Disclosure of Invention
The present invention has been accomplished in view of such circumstances. The purpose is to provide a heating toilet seat capable of suppressing excessive heat transfer to an overheat protection unit.
Means for solving the problems
The heating toilet to solve the above problems includes: a toilet seat having a seating surface; a linear heater that generates heat by energization; a heat conductive sheet including a main body portion having a shape corresponding to the toilet seat and a first clip portion extending from the main body portion and folded back toward the main body portion; and an overheat protection unit that is sandwiched between the main body unit and the first sandwiching unit, and that cuts off power supply to the linear heater when an excessive temperature rise of the toilet seat is detected, wherein when a portion of the main body unit that overlaps the first sandwiching unit when the first sandwiching unit is folded back is used as a second sandwiching unit, one of the first sandwiching unit and the second sandwiching unit has a heating surface, the other sandwiching unit has a non-heating surface, the linear heater is provided on the heating surface in a meandering manner, and the non-heating surface is not provided with the linear heater.
According to the above configuration, when the first grip portion is folded back toward the body portion, the linear heaters are prevented from being disposed close to each other at the portion where the first grip portion and the second grip portion are folded and overlapped. Therefore, excessive heat generation at the folded and overlapped portion of the first clamping portion and the second clamping portion can be suppressed. As a result, excessive heat transfer to the overheat protection unit can be suppressed.
In the above-described heating toilet, when a direction in which the first sandwiching portion extends in the heat conductive sheet is defined as an extending direction, it is preferable that the overheat protection portion be sandwiched between intermediate portions of the first sandwiching portion and the second sandwiching portion in the extending direction.
When the overheat protection portion is sandwiched between the first sandwiching portion and the second sandwiching portion at the end in the extending direction, the overheat protection portion comes into contact with the end of the heating surface in the extending direction, and therefore, the heat of the linear heater is less likely to be transmitted to the overheat protection portion. In this regard, according to the above configuration, the overheating protection portion is in contact with the intermediate portion of the heating surface in the extending direction, and therefore the heat of the linear heater is easily transmitted to the overheating protection portion. In this way, excessive heat transfer to the overheat protection unit can be suppressed, and a decrease in the responsiveness of the overheat protection unit can be suppressed.
In the heating toilet, it is preferable that the overheat protection portion is enclosed by a clamping portion having the heating surface, of the first clamping portion and the second clamping portion.
According to the above configuration, the contact area between the overheat protection portion and the linear heater can be increased as compared with a case where the overheat protection portion is enclosed by the nip portion having the non-heating surface. Therefore, the heat of the linear heater is easily transmitted to the overheat protection unit. In this way, a decrease in the responsiveness of the overheat protection unit can be suppressed.
In the above-described heating toilet, it is preferable that the overheat protection portion has a cylindrical shape, and the heating surface is provided with a plurality of linear portions and a plurality of bent portions by the linear heater provided on the heating surface, the plurality of linear portions being arranged at intervals in a direction forming an acute angle with an axial direction of the overheat protection portion, and the plurality of bent portions connecting adjacent linear portions to each other.
According to the above configuration, the contact area of the linear heater in the overheat protection portion with the linear heater is increased as compared with a case where the linear portion of the linear heater in the heating surface is arranged with a space in the direction orthogonal to the axial direction of the overheat protection portion. Therefore, the heat of the linear heater is easily transmitted to the overheat protection unit. Thus, the deterioration of the responsiveness of the overheat protection unit can be suppressed.
In the above-described heating toilet, an adhesive layer is provided between the first clamping portion and the second clamping portion, and no adhesive layer is provided between the overheating protection portion and the clamping portion having the heating surface of the first clamping portion and the second clamping portion.
According to the above configuration, the overheat protection portion can be fixed between the first clamping portion and the second clamping portion by joining the first clamping portion and the second clamping portion with the adhesive layer. On the other hand, since the adhesive layer is not provided between the holding portion having the heating surface and the overheat protection portion, the heat of the linear heater is easily transmitted to the overheat protection portion. As a result, the deterioration in the responsiveness of the overheat protection unit can be further suppressed.
In the above-described heated toilet seat, it is preferable that the adhesive layer is provided in a portion of the first nip portion and the second nip portion, the portion having the non-heated surface, other than a portion where the overheat protection portion is disposed. Preferably, the adhesive layer is a double-sided tape having an opening at a center portion thereof so as to fit the shape of the overheat protection portion.
According to the above configuration, when the overheat protection unit is disposed in the nip portion having the non-heated surface, it is easy to dispose the overheat protection unit, preferably, in a portion of the nip portion having the non-heated surface where the adhesive layer is not provided.
In the above-described heating toilet, it is preferable that the adhesive layer is a color different from that of the heat conductive sheet.
According to the above configuration, the adhesive layer is clearly distinguished from the heat conductive sheet. Therefore, when the overheat protection portion is disposed in the nip portion, it is easy to dispose the overheat protection portion in a portion of the nip portion where the adhesive layer is not provided, which is preferable.

Detailed Description
Hereinafter, an embodiment of the heating toilet will be described.
As shown in fig. 1, the heating toilet 1 includes a main body portion 10, a toilet seat 20, a toilet cover 40, and an operation portion 50, the main body portion 10 having the main functions of the heating toilet 1, the toilet seat 20 on which a user sits, the toilet cover 40 covering the toilet seat 20, and the operation portion 50 having a switch. The heated toilet 1 according to the present embodiment is used in a state of being attached to the upper surface of the toilet 60.
The main body 10 is provided at the upper rear of the toilet 60. The main body 10 includes, for example, a warm water tank that heats stored water, a cleaning nozzle unit that cleans the user's private parts with warm water supplied from the warm water tank, and a warm air dryer that blows warm air to dry the user's private parts. The main body portion 10 incorporates a control portion 11, and the control portion 11 controls the operation of the components of the heating toilet 1.
The toilet seat 20 is provided swingably with respect to the main body 10. The toilet seat 20 has a heating function to warm a seating surface 21A on which a user sits. The detailed structure of the toilet seat 20 will be described later.
The toilet cover 40 is swingably provided with respect to the main body 10, similarly to the toilet seat 20. As shown in fig. 1, the toilet lid 40 stands up to a position behind the heating toilet 1 in an opened state. In addition, the toilet cover 40 covers the upper surface of the toilet seat 20 when closed.
The operation portion 50 is provided to extend from the side surface of the main body portion 10 to the front side. The operation unit 50 has a button or the like for starting or stopping the operation of the heating toilet 1.
Next, the structure of the toilet seat 20 will be described with reference to fig. 2 to 5.
As shown in fig. 2 and 3, the toilet seat 20 includes a toilet seat upper plate 21, a toilet seat heater 30, a toilet seat lower plate 22, and an overheat protection portion 70, the toilet seat upper plate 21 has a seating surface 21A, the toilet seat heater 30 is disposed on a back surface 21B of the toilet seat upper plate 21, the toilet seat lower plate 22 accommodates the toilet seat heater 30 together with the toilet seat upper plate 21, and the overheat protection portion 70 is provided in the toilet seat heater 30.
As shown in fig. 2, the toilet seat upper plate 21 and the toilet seat lower plate 22 have a substantially elliptical shape, and a substantially circular hole is formed in the center. The toilet seat upper plate 21 and the toilet seat lower plate 22 may be joined by welding or may be connected by fastening members such as screws. The toilet seat upper plate 21 and the toilet seat lower plate 22 are formed of, for example, metal or resin.
As shown in fig. 3, the toilet seat heater 30 includes a heat conductive sheet 31 and a linear heater 32, the heat conductive sheet 31 is formed of a material having high thermal conductivity, and the linear heater 32 generates heat by energization.
The heat conductive sheet 31 is formed of a metal foil of aluminum or the like. The heat conductive sheet 31 is formed in a substantially horseshoe shape with a part of the front broken. The heat conductive sheet 31 has a body 33 and a first clip portion 34, the body 33 having a shape corresponding to the toilet seat 20, and the first clip portion 34 extending from the body 33 and folded back toward the body 33. In the following description, in the body 33, a portion overlapping the first clip portion 34 when the first clip portion 34 is folded back toward the body 33 is referred to as a second clip portion 35. In the present embodiment, the first clamping portion 34 (second clamping portion 35) has a rectangular shape in a plan view.
The linear heater 32 is provided in a meandering manner in substantially all of the region of the main body portion 33 of the heat conductive sheet 31 except for the second nip portion 35. The linear heater 32 is, for example, a sheath heater. As described above, since the linear heater 32 is provided on the entire heat conductive sheet 31 having high thermal conductivity, the seat heater 30 can uniformly transmit heat to substantially the entire region of the seat upper plate 21, and can warm the seating surface 21A of the seat upper plate 21.
The first nip portion 34 of the heat conductive sheet 31 has a heating surface 36, and the linear heater 32 is provided on the heating surface 36 in a meandering manner. On the other hand, the linear heater 32 is not provided in a meandering manner in the second nip portion 35, and the area of the second nip portion 35 where the linear heater 32 is arranged is small. Therefore, the linear heater 32 provided in the second nip portion 35 generates a small amount of heat, and the second nip portion 35 can be considered to have the non-heating surface 37. Further, the heating surface 36 of the first clamping portion 34 is provided with a plurality of linear portions 38 and a plurality of bent portions 39 by the linear heater 32, the linear portions 38 are disposed with a space in a direction orthogonal to the axial direction of the overheating protection portion 70 having a substantially cylindrical shape, and the bent portions 39 connect the adjacent linear portions 38 to each other.
The overheat protection unit 70 is a thermal fuse in which a lead wire is connected to both ends of a fusible alloy housed in a substantially cylindrical case. The overheat protection unit 70 is disposed in the middle of the current-carrying circuit of the linear heater 32. When the overheat protection unit 70 detects an excessive temperature rise of the toilet seat 20, the fusible alloy melts. Then, the melted fusible alloy is condensed and cut off to the lead wire side at both ends, and the overheat protection portion 70 cuts off the current supply to the linear heater 32. When the energization of the linear heater 32 is cut off, the overheat protection unit 70 does not return. Thus, the temperature of the toilet seat 20 does not rise excessively.
Next, a structure for attaching the overheating protection unit 70 to the toilet seat heater 30 will be described. In the present embodiment, an adhesive material 80 such as a double-sided tape is provided on the surface opposite to the surface on which the linear heater 32 of the toilet seat heater 30 is disposed.
First, as shown in fig. 3, the main body portion 33 is attached to substantially the entire rear surface 21B of the toilet seat upper plate 21, and then the overheating protection portion 70 is disposed in the toilet seat heater 30. Specifically, when the direction in which the first sandwiching portion 34 extends is defined as the extending direction X, the overheat protection portion 70 is disposed at an intermediate portion in the extending direction X of the second sandwiching portion 35. Then, as shown in fig. 4 and 5, the first clip part 34 is folded back toward the body part 33 with the overheat protection part 70 disposed in the second clip part 35. In this way, the overheat protection portion 70 is sandwiched between the first sandwiching portion 34 and the second sandwiching portion 35. In the present embodiment, when the first clip part 34 is folded back toward the body part 33, the overheating protection part 70 is enclosed along the outer shape of the overheating protection part 70 by the first clip part 34. Here, since the adhesive is provided between the first clip portion 34 and the second clip portion 35, the first clip portion 34 is adhesively fixed to the second clip portion 35 (main body portion 33). Thereby, the overheating protection part 70 is fixed to the toilet seat heater 30.
However, as shown in fig. 6, in the case of a comparative example in which the first nip portion 534 and the second nip portion 535 have the heating surface 36, unlike the present embodiment, there is a concern that: in the portion where the first nip portion 534 and the second nip portion 535 are folded and overlapped, the linear heater 532 provided in the first nip portion 534 and the linear heater 532 provided in the second nip portion 535 are in contact with each other. In this case, there is a fear that a portion where the wire heaters 532 contact each other excessively generates heat. As shown in fig. 5, in the present embodiment, the linear heaters 32 of the first and second nip portions 34 and 35 at the folded and overlapped portion are less likely to contact each other. Therefore, excessive heat generation at the folded and overlapped portion of the first clip portion 34 and the second clip portion 35 can be suppressed.
Further, since the overheating protection portion 70 is enclosed by the first sandwiching portion 34 having the heating surface 36, the contact area between the overheating protection portion 70 and the linear heater 32 can be increased as compared with the case where the overheating protection portion is enclosed by the first sandwiching portion having no heating surface. Therefore, the heat of the linear heater 32 is easily transmitted to the overheat protection unit 70.
Further, unlike the present embodiment, when the overheating protection portion is disposed at the end portion of the second sandwiching portion on the side of the first sandwiching portion in the extending direction X and when the overheating protection portion is disposed at the end portion of the second sandwiching portion on the opposite side of the first sandwiching portion in the extending direction, the overheating protection portion comes into contact with the end portion of the heating surface in the extending direction. Therefore, the heat of the linear heater is hardly transferred to the overheat protection portion. As shown in fig. 4, since the overheating protection portion 70 in the present embodiment is in contact with the intermediate portion of the heating surface 36 in the extending direction X, the heat of the linear heater 32 is easily transmitted to the overheating protection portion 70.
As described above, according to the present embodiment, the following effects can be obtained.
(1) Since the linear heaters 32 can be prevented from being disposed close to each other in the portion where the first and second nip portions 34 and 35 are folded and overlapped, excessive heat generation in the portion where the first and second nip portions 34 and 35 are folded and overlapped can be prevented. As a result, excessive heat transfer to the overheat protection unit 70 can be suppressed.
(2) Since the overheating protection portion 70 is in contact with the intermediate portion of the heating surface 36 in the extending direction X, the heat of the linear heater 32 is easily transmitted to the overheating protection portion 70. In this way, excessive heat transfer to the overheat protection unit 70 can be suppressed, and a decrease in the responsiveness of the overheat protection unit 70 can be suppressed.
(3) The contact area between the overheating protection part 70 and the linear heater 32 can be increased as compared with the case where the overheating protection part is enclosed by a nip part having a non-heated surface. Therefore, the heat of the linear heater 32 is easily transmitted to the overheat protection portion 70. In this way, a decrease in the responsiveness of the overheat protection unit 70 can be suppressed.
The above embodiment may be modified as follows.
As shown in fig. 7, the non-heated surface 37 may be provided in the first nip portion 134 and the heated surface 36 may be provided in the second nip portion 135. Further, as in the present embodiment, the first clip part 134 may be folded back toward the side of the body 133 where the adhesive 80 is not provided. As shown in fig. 8, unlike the present embodiment, the first clip part 134 may be folded back toward the side of the body 133 on which the adhesive material 80 is provided. Since an adhesive is provided on the contact surface between the first clip portion 134 and the toilet seat upper plate 21, the first clip portion 134 is adhesively fixed to the back surface 21B of the toilet seat upper plate 21.
As shown in fig. 9, the first clip part 234 may be folded back toward the body part 233 with the overheat protection part 70 disposed at the end of the second clip part 235 on the first clip part 234 side in the extending direction X. In addition, as in the modification of fig. 8, the first clip part 234 may be folded back toward the side of the body part 233 on which the adhesive 80 is provided. Further, the overheat protection unit 70 may be disposed at an end portion of the second clip portion 235 opposite to the first clip portion 234 in the extending direction X, and the first clip portion 234 may be folded back to the body portion 233.
In the present embodiment, the first clip part 34 may be folded back toward the side of the body part 33 on which the adhesive material 80 is provided. In this case, the overheat protection portion 70 is disposed on the side of the second sandwiching portion 35 where the adhesive 80 is provided.
As shown in fig. 10, the plurality of linear portions 338 of the heating surface 36 may be arranged at intervals in a direction forming an acute angle with the axial direction of the overheating protection portion 70. Thus, the contact area of the linear heater 332 in the overheating protection portion 70 is larger than that in the case where the linear portion of the linear heater in the heating surface is arranged with a space in the direction orthogonal to the axial direction of the overheating protection portion. Therefore, the heat of the linear heater 332 is easily transmitted to the overheating protection portion 70. In this way, the deterioration of the responsiveness of the overheat protection unit 70 can be further suppressed.
As shown in fig. 11, an adhesive layer 90 may be provided on the second sandwiching portion 435 having the non-heating surface 37, and the overheat protection portion 70 may be fixed between the first sandwiching portion 34 and the second sandwiching portion 435 by the adhesive layer 90. The adhesive layer 90 may be a double-sided tape, for example, as long as the first clamping portion 34 and the second clamping portion 435 are joined. Accordingly, the adhesive layer 90 may be the same material as the double-sided tape used as the adhesive material 80. As shown in fig. 12, in the case where the first clip part 34 is folded back toward the body part 33 in a state where the overheat protection part 70 is disposed in the second clip part 435, the adhesive layer 90 is provided between the first clip part 34 and the second clip part 435, and the adhesive layer 90 is not provided between the overheat protection part 70 and the second clip part 435. On the other hand, the adhesive layer 90 is not provided between the first sandwiching portion 34 having the heating surface 36 and the overheating protection portion 70.
Thus, the first clip part 34 and the second clip part 435 are joined by the adhesive layer 90, and the overheating protection part 70 and the second clip part 435 are joined by the adhesive layer 90, whereby the overheating protection part 70 can be fixed between the first clip part 34 and the second clip part 435. On the other hand, since the adhesive layer 90 is not provided between the first sandwiching portion 34 having the heating surface 36 and the overheating protection portion 70, the heat of the linear heater 32 is easily transmitted to the overheating protection portion 70. As a result, the deterioration of the responsiveness of the overheat protection unit 70 can be further suppressed.
The adhesive layer 90 may be provided on the first nip portion 34 having the heating surface 36. In this case, the first clip part 34 is folded back toward the body part 33 with the overheat protection part 70 disposed in the second clip part 35, and in this case, the adhesive layer 90 is preferably not provided between the first clip part 34 having the heating surface 36 and the overheat protection part 70.
As shown in fig. 13, in the second nip portion 535 having the non-heated surface 37, the adhesive layer 91 may be provided in a portion other than the portion where the overheat protection portion 70 is disposed. That is, the adhesive layers 91 may be provided on both sides of the region where the overheat protection portions 70 are disposed in the extending direction X. When the adhesive layer 91 is colored differently from the heat conductive sheet 31, the adhesive layer 91 is clearly distinguished from the heat conductive sheet 31. Accordingly, when the overheating protection part 70 is disposed in the second sandwiching part 535, it is easy to dispose the overheating protection part 70 in a point that the overheating protection layer 70 is preferably disposed in a portion of the second sandwiching part 535 where the adhesive layer 90 is not provided. The adhesive layer 91 may be formed of a double-sided tape having an opening at the center thereof so as to fit the shape of the overheat protection unit.
The overheat protection unit 70 may be constituted by a thermostat, for example. Therefore, after the operation of cutting off the power supply to the linear heater 32 is performed by detecting an excessive increase in the temperature of the toilet seat 20, the temperature of the toilet seat is automatically or manually returned when the temperature thereof decreases to a predetermined temperature.
In the above embodiment, the main body 31 may be attached to the back surface 21B of the toilet seat upper plate 21 using an adhesive. In addition, the first clip portion 34 may be bonded to the second clip portion 35 by using an adhesive.
In the present embodiment, the first clip portion 34 may be fixed to the second clip portion 35 (main body portion 33) by attaching an aluminum tape so as to cover a portion where the first clip portion 34 and the second clip portion 35 are folded and overlapped.
The first and second clamping portions 34 and 35 may be provided with a non-heating surface 37. Therefore, when the first clip part 34 is folded back toward the body part 33, the linear heater 32 is not provided in the portion where the first clip part 34 and the second clip part 35 are folded and overlapped, and therefore, excessive heat generation in the portion where the first clip part 34 and the second clip part 35 are folded and overlapped can be suppressed. As a result, excessive heat transfer to the overheat protection unit 70 can be suppressed.
The heating surface 36 may be provided on a contact surface of the second clamping portion 35 that contacts the overheating protection portion 70. Accordingly, the linear heater 32 can be provided on the surface of the first clamping portion 34 and the second clamping portion 35 that is in contact with the overheat protection portion 70, and therefore, the heat of the linear heater 32 is easily transmitted to the overheat protection portion 70. In this way, a decrease in the responsiveness of the overheat protection unit 70 can be suppressed.
A lead wire for passing a current through the overheat protection portion 70 may be fixed between the first clamping portion 34 and the second clamping portion 35. Thus, the heat of the linear heater 32 is easily transmitted to the overheating protection unit 70, since the heat of the linear heater 32 is transmitted to the lead of the overheating protection unit 70 and hardly escapes. As a result, the deterioration of the responsiveness of the overheat protection unit 70 can be further suppressed.
