Description

Heated toilet seat unit

technical field

The utility model relates to a heating toilet seat device installed with a toilet cover, and the toilet cover has a heat insulation function.

Background technique

Conventionally, such a heated toilet seat device has a structure in which a toilet lid covering the toilet seat is formed into a hollow double-layer structure, and a heat insulating material is accommodated in the hollow portion to obtain a heat insulating effect. Thereby, the thermal insulation effect of the toilet seat with a built-in heating part is improved.

However, if the toilet lid is formed into a double structure, the toilet lid will become thicker. Therefore, detection areas of sensors such as a human body detection sensor and a seating detection sensor that function when the toilet lid is opened interfere with a part of the toilet lid, thereby obstructing the sensor function in some cases.

Therefore, for example, Japanese Patent Application Laid-Open No. 2010-178923 discloses a heated toilet seat device with a structure in which the thickness of the central part of the toilet cover is formed thinner than that of the surrounding area so as not to interfere with the detection area and the toilet cover (hereinafter , denoted as "Patent Document 1").

Hereinafter, the structure of the conventional heating toilet seat apparatus described in patent document 1 is demonstrated using FIG. 8. FIG. Fig. 8 is a sectional view of a conventional heated toilet seat device.

As shown in FIG. 8 , in the conventional heated toilet seat device, the toilet seat 2 and the toilet lid 3 are rotatably pivotally supported on the main body 1 . The toilet lid 3 is constituted by a double-layer structure of a toilet lid main body 4 and a bottom plate 5 , and a heat insulator 6 is accommodated between the toilet lid main body 4 and the bottom plate 5 . At this time, the toilet lid 3 is formed such that the thickness T1 of the central portion of the toilet lid 3 is thinner than the thickness T2 of the periphery. Thereby, it is set as the structure which does not interfere with the detection area S of the toilet lid 3 and a sensor (not shown).

That is, the conventional heated toilet seat device realizes a structure in which the toilet lid 3 does not interfere with the detection area of the sensor when the toilet lid 3 is opened.

However, in the state where the toilet lid 3 is closed, the toilet lid 3 enters the detection area of the sensor, so that human body detection or seat detection erroneous detection occurs.

Therefore, the conventional heated toilet seat device is separately provided with an angle sensor for detecting the opening and closing angle of the toilet lid, and a toilet lid opening and closing sensor for detecting the opening and closing state of the toilet lid, etc. separately. In addition, when the toilet lid is not in the open state by the toilet lid open/close sensor, the function of the human body detection sensor and the seating detection sensor is stopped, or the received detection signal is canceled, so as to eliminate the above-mentioned erroneous detection.

However, if the toilet lid opening/closing sensor is provided separately, there is a problem of structural restriction and cost burden increasing. In particular, in a general-purpose heated toilet seat device having only a seating detection sensor, the ratio of cost increase due to the installation of a toilet lid opening and closing sensor to a product is high. Therefore, there is room for improvement in terms of structure, cost, and the like.

The planar shape of the upper surface part 411 is formed in a substantially similar shape (including a similar shape) to the outer shape of the toilet seat 300 , and covers the entire upper surface of the toilet seat 300 in the closed state. On the other hand, the side surface part 412 of the upper surface part 411 is formed in the shape which covers a part of the side surface of the toilet seat 300. As shown in FIG.

Furthermore, the upper surface part 411 of the toilet lid main body 410 has the holding part 413 which holds the cushioning member 430 at two places on the front inner surface of the upper surface part 411. As shown in FIG. The holding part 413 is integrally formed with the rib 413a as four sides, and is formed in a box shape, for example.

In addition, as for the side part 412 of the toilet lid main body 410, the two rear end parts of the side part 412 are integrally provided with the shaft support shown in FIG. part 414 and a circular shaft support part 414 not shown. And, utilize the elasticity of the side part 412 of the toilet lid main body 410 that is made of resin material, expand the end part 412a of the side part 412, thereby, make the shaft support part 414 of the side part 412 relative to the rotation shaft of the main body 200 detachable. .

At this time, the outer shape of one shaft support portion 414 not shown in FIG. 4 is formed in a circular shape with a single diameter.

On the other hand, the outer shape of another shaft support portion 414 shown in FIGS. 4 and 6 is formed in a deformed shape composed of two circles with different diameters. Specifically, the other shaft support portion 414 is formed in a deformed shape in which a stepped portion 414a is formed at a joint portion of a different diameter. Thus, the stepped portion 414 a of the other shaft support portion 414 limits the rotation angle of the toilet lid 400 . That is, the rotation angle of the toilet lid 400 is restricted by making the stepped portion 414 a of the shaft support portion 414 abut against a restricting portion (not shown) provided on the main body 200 .

In addition, the toilet lid inner surface member 420 is configured by integrally forming a flat surface portion 421 , a support portion 422 , and a reinforcing rib 423 . The planar portion 421 is formed in a substantially similar shape (including a similar shape) to the upper surface portion 411 of the toilet lid main body 410 . The support portion 422 is formed by cutting out the both side portions 421b of the rear portion 421a of the planar portion 421 in a perpendicular direction. Reinforcing ribs 423 are provided near the rear end of the outer periphery of the planar portion 421 and a part of both side portions 421 b to reinforce the strength of the planar portion 421 . The support portion 422 and the reinforcing rib 423 are respectively formed on the surface on the opposite side of the flat surface portion 421 (the surface facing the toilet lid main body).

In addition, for example, cylindrical holding portion insertion holes 424 are provided at two places on the front side of the flat surface portion 421 of the toilet lid inner surface member 420 . The holding part insertion hole 424 is formed by integrally molding the rib 424 a with four sides for inserting the holding part 413 formed in the toilet lid main body 410 .

Moreover, the shaft support part insertion hole 425 is provided in the rear end part of the support part 422 of the toilet lid inner surface member 420. As shown in FIG. In addition, the shaft support portion 414 formed on the toilet lid body 410 is inserted into the shaft support portion insertion hole 425 . At this time, the shaft support portion insertion hole 425 has a shape corresponding to the left and right shaft support portions 414 having different outer shapes formed on the side surface portion 412 of the toilet lid body 410 as described above. As a result, insertion is only possible in a predetermined direction, preventing wrong insertion. And, the end 422a of the support portion 422 is deformed by the elasticity of the support portion 422 of the toilet lid inner surface member 420 made of a resin material, thereby making the shaft support portion 414 of the toilet lid main body 410 relative to the toilet lid inner surface member 420. The shaft support part insertion hole 425 can be attached and detached.

In addition, as shown in FIGS. 3 to 5 , a recessed portion 426 recessed upward (towards the upper surface portion 411 of the toilet lid body 410 ) is provided at the center of the flat portion 421 of the toilet lid inner surface member 420 . Moreover, the recessed part 426 is formed from the rear part 421a of the flat part 421 of the toilet lid inner surface member 420 to the vicinity of the front part 421c.

And, usually, as shown in FIG. 3 , in the state after the toilet lid main body 410 and the toilet lid inner surface member 420 are assembled, the toilet lid main body 410 and the toilet lid inner surface member 420 are constituted in the toilet lid inner surface member 420. A portion of the recessed portion 426 is formed with a gap 401 of, for example, 1 mm or less. However, there is a part where the toilet lid main body 410 and the toilet lid inner surface member 420 abut against due to variations in the shape of the components or the like. On the other hand, on both sides of the recessed portion 426 of the toilet lid inner surface member 420 , a gap 401 of about 3 cm at maximum is formed between the toilet lid main body 410 and the toilet lid inner surface member 420 . Thereby, the air heat insulation effect by a clearance gap can be acquired.

In addition, as shown in FIG. 3 and FIG. 7 , the buffer member 430 is integrally formed with a leg portion 431 and an abutment portion 432 , the leg portion 431 is embedded in the holding portion 413 of the toilet lid main body 410 , and the abutment portion 432 is in contact with the upper surface of the toilet seat 300 . The buffer member 430 absorbs the impact when the toilet lid 400 and the toilet seat 300 abut against each other. In addition, the leg portion 431 of the buffer member 430 is configured so as not to fall off easily by being press-fitted into the holding portion 413 . In addition, the abutting portion 432 of the cushioning member 430 is larger in size than the leg portion 431 and is formed in a shape to straddle and block the holding portion insertion hole 424 , for example. Thereby, the toilet lid main body 410 and the toilet lid inner surface member 420 are fixed by the abutting portion 432 of the buffer member 430 so that they are not easily detached.

Hereinafter, the method of assembling the toilet seat of the heated toilet seat device of the present embodiment will be briefly described.

First, as shown in FIGS. 4 to 7 , regarding the assembly of the toilet lid 400 , the toilet lid inner surface member 420 is arranged on the inner surface of the toilet lid main body 410 .

Next, using the elasticity of the toilet lid inner surface member 420 made of resin material, the shaft support portion 414 of the toilet lid body 410 is inserted into the shaft support portion insertion hole 425 of the toilet lid inner surface member 420 . Thereby, the rear part 421a of the toilet lid inner surface member 420 is engaged with the toilet lid main body 410. As shown in FIG.

Next, the holding portion 413 of the toilet lid main body 410 is inserted into the holding portion insertion hole 424 of the toilet lid inner surface member 420 . Then, the buffer member 430 is pressed into the holding portion 413 of the toilet lid main body 410 from the toilet lid inner surface member 420 side in the inserted state. Thereby, the front part 421c of the toilet lid inner surface member 420 is engaged with the toilet lid main body 410 by the contact part 432 of the buffer member 430. As shown in FIG.

At this time, as shown in FIG. 2 and FIG. 3 , the outer periphery of the toilet lid inner surface member 420 and the inner surface of the toilet lid main body 410 are not completely in contact, and at least a part is formed with a slit-shaped opening of 1 mm or less. Next, the toilet lid body 410 , the toilet lid inner surface part 420 and the cushioning part 430 are assembled. In addition, the opening formed on the outer periphery of the toilet lid inner surface member 420 (the gap between the side surface portion 412 of the toilet lid main body 410 and the toilet lid inner surface member 420 ) is an interval that can prevent the air in the gap 401 from leaking to the outside. . Therefore, the gap 401 formed between the toilet lid main body 410 and the toilet lid inner surface member 420 is maintained in a nearly airtight state. In addition, the reinforcement rib 423 formed in the toilet lid inner surface member 420 also has the effect of suppressing the air flow inside the gap 401 between the toilet lid main body 410 and the toilet lid inner surface member 420 . Thereby, the heat insulation effect by the gap 401 can be improved.

Next, for the toilet lid 400 assembled through the above steps, the shaft support part 414 is inserted into the rotation shaft (not shown) of the main body 200 by utilizing the elasticity of the resin material forming the toilet lid 400 . Thus, the toilet lid 400 is rotatably installed on the main body 200 .

Through the above steps, the toilet seat of the heated toilet seat device is assembled.

(3) Action and function of the heated toilet seat device

Hereinafter, the operation|movement and effect|action of the heated toilet seat apparatus concerning embodiment of this invention are demonstrated with reference to FIG.2 and FIG.3.

Normally, in the standby state where the heated toilet seat device is not used, the heated toilet seat device is placed with the toilet lid closed as shown in FIGS. 2 and 3 . At this time, the seating surface 310 of the toilet seat 300 is kept warm by the toilet seat heater built in the toilet seat 300 at a temperature at which the user does not feel cold even when sitting down, that is, a standby temperature of, for example, 29 to 31 degrees.

In addition, in the heated toilet seat device of the present embodiment, the toilet lid 400 covering the top of the toilet seat 300 is constituted by a two-layer structure of the toilet lid main body 410 and the toilet lid inner surface member 420 . And, as shown in FIG. 3 , on both sides of the toilet lid 400 disposed above the toilet seat 300 , through the recessed portion 426 of the toilet lid inner surface member 420 , the toilet lid main body 410 and the toilet lid inner surface member 420 are connected. A gap 401 is formed therebetween. Thereby, a high thermal insulation effect is achieved.

In addition, the seating detection sensor 210 always maintains an operating state capable of detecting a human body in the standby state. That is, as shown in FIG. 2 , infrared rays are irradiated forward from the main body 200 to the range of the detection region W shown by hatching in FIG. 2 .

At this time, in the heated toilet seat device of the present embodiment, the recessed part 426 is formed in the center part of the toilet lid inner surface member 420 of the toilet lid 400 . Therefore, the detection area W of the seating detection sensor 210 does not interfere with the toilet lid inner surface member 420 even when the toilet lid 400 is closed. Thereby, it can prevent that the seating detection sensor 210 erroneously detects the toilet lid 400 as a human body.

That is, in the state where the toilet lid 400 is closed, the sitting detection sensor 210 maintains the state where no sitting is detected. In addition, the control unit cancels the operation signal of the operation switch 230 of the washing unit or the like used at the time of seating in a state where the seating is not detected. Specifically, even if the operation switch 230 of the washing unit is operated, for example, it is configured so that misoperations such as spraying of washing water are prevented.

Next, when the user opens the toilet lid 400 and sits on the toilet seat 300 , the infrared rays irradiated from the seating detection sensor 210 are reflected on the human body. And, the reflected light reflected by the human body is received by the seating detection sensor 210 . Thereby, the sitting detection state of the human body sitting on the toilet seat 300 is detected.

Next, when it is detected that the user sits down, the control unit controls the toilet seat heater to be energized. Specifically, the control unit controls the energization of the toilet seat heater so that the temperature of the seating surface 310 becomes a warm temperature of 29 to 37 degrees, which is higher than the standby temperature and comfortable after sitting. In addition, the heat-retaining temperature can be changed stepwise by the operation switch 230 provided on the sleeve portion 220 of the main body 200 .

At this time, the control unit also changes the standby temperature in conjunction with the change of the keep warm temperature. For example, when the keep warm temperature is set to 29 degrees, the standby temperature is set to 29 degrees. In addition, when the heat preservation temperature is 33 degrees, the standby temperature is set to 30 degrees. Furthermore, when the heat preservation temperature is 37 degrees, the standby temperature is set to 31 degrees.

Then, the seat detection sensor 210 ends the seat detection, and the control unit changes the energization pattern of the toilet seat heater after a predetermined time elapses (for example, after 3 minutes). Then, the control unit controls so that the temperature of the toilet seat 300 changes from the warm temperature to the standby temperature.

Moreover, in the state which detected sitting, the control part controls and drives each function, such as the washing|cleaning part of a heating toilet seat apparatus, based on the operation signal of the operation switch 230. FIG. At this time, when the user stands up while each function is being driven, the sitting detection sensor 210 ends the sitting detection. In this case, the control unit immediately stops each function being driven. Thereby, the safety of a heated toilet seat device can be ensured.

In addition, since the operation and function of the subsequent heated toilet seat device are the same as those of the conventional heated toilet seat device, description thereof will be omitted.

As described above, the heated toilet seat device 100 of the present embodiment has a thermal insulation effect, which is produced because the toilet lid 400 has a double structure with a gap 401 provided between the toilet lid main body 410 and the toilet lid inner surface member 420. of. Thereby, heat radiation from the toilet seat 300 in the state which closed the toilet lid 400 can be suppressed. As a result, a high energy saving effect can be obtained.

In addition, the heated toilet seat device 100 of the present embodiment has a structure in which a recessed portion 426 is provided at the center of the toilet lid inner surface member 420 constituting the toilet lid 400 so that the toilet seat can be discharged with the toilet lid 400 closed. Interference between the cover inner surface member 420 and the detection area W of the seating detection sensor 210 . Accordingly, it is not necessary to provide another sensor for detecting the open/close state of the toilet lid 400 , and it is possible to suppress false detection by the seating detection sensor 210 . As a result, a highly reliable heated toilet seat device can be realized at low cost.

Moreover, in the heated toilet seat device 100 of this embodiment, the recessed part 426 is provided in the toilet lid inner surface member 420 which comprises the toilet lid 400. As shown in FIG. Thereby, the planar strength of the toilet lid inner surface member 420 is enhanced, and therefore the wall thickness of the toilet lid inner surface member 420 can be reduced. As a result, the weight of the toilet lid inner surface member 420 can be reduced.
