  According to the present invention, there is provided a heated toilet seat device in which a hot air outlet is provided in a casing that pivotally supports a toilet seat, and hot air is introduced into the toilet seat from the outlet, even after the toilet seat is raised and the toilet is used. It is possible to provide a heated toilet seat device that can heat the toilet seat more reliably and a toilet device including the same.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view of a toilet apparatus provided with a heating toilet seat apparatus according to an embodiment of the present invention.

  The heating toilet seat device of this specific example includes a casing 500 provided on the upper part of the flush toilet 300. The washing mechanism of the flush toilet 300 may be a so-called “low tank type” or a “water direct pressure type” that does not use a low tank.

  A toilet seat 410 and a toilet lid 400 are pivotally supported on the casing 500 so as to be freely opened and closed. As will be described in detail later, the toilet seat 410 and the toilet lid 400 can be manually opened and closed, and can be automatically opened and closed by an electric opening and closing mechanism. And in this embodiment, the warm air supply means 550 is provided in the casing 500, and the toilet seat 410 can be heated by introducing the warm air into the closed (lowered) toilet seat 410. . This will be described in detail later.

  Furthermore, the casing 500 may be provided with a functional unit as a sanitary washing device. In other words, the heating toilet seat apparatus appropriately includes a cleaning function unit having a water discharge nozzle 615 that ejects water toward a “butt” of a user sitting on the toilet seat 410. In the present specification, “water” includes not only cold water but also heated hot water. The heated toilet seat device is also equipped with a warm air drying function that blows hot air toward the user's “buttock” sitting on the toilet seat, etc., and the air in the bowl of the toilet bowl is sucked through a filter or catalyst. It can have a deodorizing function for reducing odor components. These operations may be operable by a remote controller 200 provided separately from the casing 500, for example. However, in the present invention, the water discharge nozzle 615 and other additional function units do not necessarily have to be provided, and the hot air heating mechanism of the toilet seat 410 and the electric opening / closing mechanism of the toilet seat 410 may be provided.

FIG. 2 is a conceptual diagram illustrating the toilet seat heating mechanism of the present embodiment.
In the casing 500, for example, a fan 552 and a heater 554 are provided as the hot air supply means 550. The air sent out from the fan 552 is heated by the heater 554 to generate hot air, and this hot air is introduced into the toilet seat 410 in a closed (lowered) state via the sending unit 560. A warm air path 412 is formed in the toilet seat 410, and the warm air introduced from the sending section 560 into the air path 412 of the toilet seat 410 flows through the toilet seat 410 and passes through the return section 570. Return to the hot air supply means 550 of the casing 500. That is, the toilet seat heating mechanism of this specific example forms a circulation path of the warm air supply means 550, the delivery section 560, the air path 412, the return section 570, and the hot air generation means 550 in a state where the toilet seat 410 is closed, Hot air is allowed to flow repeatedly through this circuit. If it does in this way, exhaust air will be suppressed and warm air heating excellent in thermal efficiency will be attained. The operation of the warm air heating mechanism can be controlled by the remote controller 200, for example. That is, the temperature of the toilet seat 410 can be displayed on the remote controller 200 or the temperature can be set.

  In the delivery section 560, a hot air outlet is provided on the casing 500 side, and an inlet corresponding to the outlet is provided on the toilet seat 410 side. The return part 570 can also be provided with a warm air outlet on the toilet seat 410 side and an inlet corresponding to the outlet on the casing 500 side. Still further, as described in, for example, Patent Document 2, in the delivery unit 560 and the return unit 570, the air outlet is protruded into the duct, or the open / close plate is advanced into the duct. You may provide the mechanism which suppresses the leakage of this. As will be described later with reference to FIG. 9, the return portion 570 may be adjacent to the sending portion 560.

  As described above, in the present embodiment, warm air can be introduced into the toilet seat 410 in a closed state to enable heating. According to the present embodiment, since the toilet seat 410 and the casing 500 are not connected to each other by a duct that can be expanded and contracted like the warm air heating toilet seat disclosed in Patent Document 1, the toilet seat 410 is removed from the casing 500 for cleaning. When washing with water, it can be easily removed and reattached.

However, in the case of the toilet seat heating mechanism of the present embodiment, hot air cannot be introduced from the casing 500 into the toilet seat 410 when the toilet seat 410 is opened.
On the other hand, if an “automatic open / close mode” using the electric opening / closing mechanism of the toilet seat 410 and the toilet lid 400 is provided, the toilet seat 410 can be automatically closed after the user leaves, and hot air heating is resumed. it can. However, even in that case, if the automatic open / close mode is set to “off”, the toilet seat 410 is not automatically closed, so that the hot air heating cannot be resumed. On the other hand, in this embodiment, even when the automatic opening / closing mode is prohibited, if the human body is not detected after the toilet is used, the toilet seat 410 (or the toilet seat 410 and the toilet lid 400) is automatically It is possible to execute “forced closing mode” that closes at the same time. Hereinafter, the automatic opening / closing mode will be described first.

FIG. 3 is a schematic diagram for explaining the automatic opening / closing mode.
That is, as shown in FIG. 3A, in the standby state, the toilet seat 410 and the toilet lid 400 are in a closed state. When the user 10 approaches the toilet and enters the toilet room as shown in FIG. 3B, sensors provided in the casing 500, the remote controller 200, and the like detect this. Then, the toilet lid 400 automatically opens. Here, the toilet seat 410 may be opened at the same time.

  For example, as shown in FIG. 3C, the user 10 opens the toilet seat 410 manually or by operating a switch of the remote controller 200 and uses the toilet 300. Thereafter, when the user 10 leaves the toilet room, this is detected by a sensor provided in the casing 500 or the remote controller 200, and the toilet seat 410 and the toilet lid 400 are automatically closed. The sensor may detect that the human body has moved from the front of the toilet, and the toilet seat 410 and the toilet lid 400 may be automatically closed.

  Thus, in the state in which the automatic opening / closing mode is on, the toilet seat 410 is automatically closed when the user 10 leaves or moves from the front of the toilet bowl 300. Therefore, as described above with reference to FIG. Hot air can be introduced into 410 and heating is possible.

However, such an automatic opening / closing mode can be stopped by the setting of the user 10 using the remote controller 200, for example.
FIG. 4 is a schematic view illustrating an on / off switch in the automatic opening / closing mode provided in the remote controller 200.
On the upper surface of the remote controller 200, infrared transmissive windows 231 for communication with the casing 500 are provided at both ends thereof. Further, a large washing switch 232, a small washing switch 234, a toilet lid closing switch 236, a toilet lid opening switch 238, a toilet seat opening switch 240, and the like are provided.

  Various setting switches are provided on the front surface of the remote controller 200. The remote controller of this specific example is also provided with an on / off switch 250 for the auto open / close mode. Each time the user presses the switch 250, the automatic opening / closing mode is switched between on and off.

  In the state where the automatic opening / closing mode is off, the toilet seat 410 and the toilet lid 400 are opened and closed manually or by operating the remote controller 200, as illustrated in FIG. When the user 10 leaves as it is after use, as shown in FIG. 5D, the toilet seat 410 remains open. However, in this state, warm air cannot be introduced from the casing 500 to the toilet seat 410, and warm air heating of the toilet seat 410 cannot be resumed.

On the other hand, in the present embodiment, in a state where the automatic opening / closing mode is prohibited, when the user 10 leaves, a forced closing mode for forcibly closing the toilet seat 410 is executed. 6 and 7 are schematic views illustrating the operation of the toilet seat 410 in the forced closing mode according to the present embodiment.
That is, when the automatic opening / closing mode is off, the toilet lid 400 or the like is not opened even when the user 10 approaches the toilet device as shown in FIG. Then, the user 10 opens the toilet seat 410 manually or by operating the remote controller 200, uses the toilet 300, and leaves the toilet room as it is. Then, even when the automatic opening / closing mode is off, the toilet seat 410 is automatically closed as shown in FIG.

  In this way, as described above with reference to FIG. 2, heating can be resumed by introducing warm air from the casing 500 to the toilet seat 410.

  In this case, as illustrated in FIG. 7D, the toilet lid 400 may be closed together with the toilet seat 410 after the user 10 leaves the toilet room. By closing the toilet lid 400 as well, an effect of suppressing heat dissipation from the toilet seat 410 and maintaining heat can be obtained.

  As described above, in this embodiment, the toilet seat 410 is forcibly closed when it is detected that the user has left or moved from the front of the toilet 300 even when the automatic open / close mode is off. To do. By doing so, the warm air heating mechanism can be operated to restart the heating of the toilet seat 410 by the hot air.

Hereinafter, embodiments of the present invention will be described in more detail with reference to specific examples.
FIG. 8 is a block diagram illustrating the basic configuration of the heating toilet seat device of the present embodiment.
As a warm air heating mechanism for introducing warm air into the toilet seat 410, a first temperature detection unit 540, a blower unit 552, a heating unit 554, and a second temperature detection unit 542 are provided. The first temperature detection unit 540 measures the temperature of the warm air that has returned from the air passage 412 provided in the toilet seat 410. The air blowing unit 552 forms a flow for circulating the warm air. The heating unit 554 heats the hot air to be inserted to a predetermined temperature. The second temperature detection unit 542 detects the temperature of the warm air sent to the toilet seat 410. Control unit 510 controls operations of air blowing unit 552 and heating unit 554 based on the detection results of first temperature detection unit 540 and second temperature detection unit 542.

FIG. 9 is a conceptual diagram illustrating a warm air heating mechanism.
The casing 500 is provided with a blowing unit 552 and a heating unit 554. The blower 552 is provided with a first damper 546 and a second damper 548. FIG. 9 shows a state in which the first damper 546 is closed and the second damper 548 is opened. In this state, a circulation air passage including the air passage 412 of the toilet seat 410 is formed. On the other hand, when the first damper 546 is opened and the second damper 548 is closed, an operation of introducing and heating outside air is performed. This is executed, for example, during a hot air drying operation in which hot air is blown out from a damper provided in a return portion 570 (not shown) and a blowout duct following the damper toward the “butt” of the user sitting on the toilet seat 410. be able to.
The first temperature detection unit 540 is provided on the air path of the warm air that has returned from the air path 412 of the toilet seat 410 to the casing 500 via the return part 570. On the other hand, the second temperature detection unit 542 is provided on the air path of the warm air heated by the heating unit 554.

FIG. 10 is a conceptual diagram illustrating the cross-sectional structure of the delivery unit 560. As shown in FIG.
In the case of this specific example, the casing 500 is provided with a protruding air outlet 562. A damper 564 is provided at the tip of the air outlet 562 so as to be freely opened and closed. The air outlet 562 may be retracted when the toilet seat 410 is opened, and the front end surface of the casing 500 may be a substantially flat surface. In the state where the toilet seat 410 is closed, as shown in FIG. 10, the air outlet 562 protrudes and is inserted into the introduction port 414 provided in the toilet seat 410. That is, only in this state where the toilet seat 410 is closed, the air outlet 562 and the introduction port 414 are joined, and hot air can be introduced into the air passage 412 of the toilet seat 410. Further, by appropriately providing a packing 568 made of an elastic material around the duct 562, it is possible to suppress the “leak” of warm air in the delivery unit 560.

Returning to FIG. 8 again, the heating toilet seat apparatus further includes a human body detection unit 520, an environmental temperature detection unit 522, a surface temperature estimation unit 524, a temperature setting unit 526, a toilet lid electric opening / closing unit 528, and a toilet lid. An opening / closing detection unit 530, a toilet seat electric opening / closing unit 532, a toilet seat opening / closing detection unit 534, and the like are provided as appropriate.
The human body detection unit 520 detects, for example, the presence or absence of a user in the toilet room using a pyroelectric sensor, an infrared light projection sensor, a microwave sensor, or the like. These sensors may be provided in the casing 500, may be provided in the remote controller 200 (see FIG. 1 or the like), or may be provided as a separate sensor unit (not shown) for the casing 500 and the remote controller 200. . For example, if a sensor unit using a pyroelectric sensor is arranged near the entrance in a toilet room, a user who enters the toilet can be detected more quickly.

  Moreover, you may comprise the human body detection part 520 with a some sensor. For example, a pyroelectric sensor may be used to detect the user entering the toilet room, and an infrared light projection sensor may be used to detect the presence of the user in the toilet room. Further, a seating sensor that detects a user who is sitting on the toilet seat 410 may be included.

The environmental temperature detection part 522 detects the environmental temperature of the surroundings where the heating toilet seat apparatus is arrange | positioned. For example, it is possible to feed back to the operation of the hot air heating mechanism by measuring the temperature of the toilet room in which the heating toilet seat device is installed.
Further, the surface temperature estimation unit 524 estimates the temperature of the seat surface of the toilet seat 410. For example, the temperature of the seat surface of the toilet seat 410 is estimated based on the detection results of the first temperature detection unit 540 and the second temperature detection unit 542 and further adding the detection result of the environmental temperature detection unit 522 to this. Then, based on the difference between the estimated temperature and the set temperature, the operations of the air blowing unit 552 and the heating unit 554 are controlled.

  The temperature setting unit 526 sets the temperature of the toilet seat 410. For example, the target temperature of the toilet seat 410 can be set by operating a switch of the remote controller 200.

The toilet lid electric opening / closing unit 528 opens and closes the toilet lid 400 electrically. The structure will be described later with a specific example.
The toilet lid opening / closing detection unit 530 detects the opening / closing state of the toilet lid 400.
Similarly, the toilet seat electric opening / closing part 532 opens and closes the toilet seat 410 by electric drive.
The toilet seat opening / closing detection unit 534 detects the opening / closing state of the toilet seat 410.

FIG. 11 is a block diagram illustrating the configuration of the toilet lid electric opening / closing unit 528 and the toilet seat electric opening / closing unit 532.
The toilet lid electric opening / closing part 528 (toilet seat electric opening / closing part 532) of this specific example can be built in the casing 500, and its output shaft 728 can be rotated by a motor 721. The drive mechanism detects a rotation speed of the output shaft 728, a speed reduction mechanism 722 that decelerates the rotation output of the motor 721, a torque limiter 723 that restricts the maximum torque to be loaded, an angle stopper 724 that regulates the rotation angle of the output shaft 728, and the like. And an assist spring (elastic body) 726 that applies an urging force to the output shaft 728. The reduction mechanism 722 includes a rotation detection unit 722A, a bevel gear 722B, a worm gear 722C, a spur gear 722D, a planetary gear 722E, and the like.

  By using such an electric opening and closing unit, the toilet lid 400 and the toilet seat 410 can be opened and closed electrically. In addition, the toilet lid 400 and the toilet seat 410 can be manually opened and closed even when the electric opening / closing part is attached. In both cases of electric driving and manual driving, the toilet lid 400 and the toilet seat 410 can be lightly opened by providing the assist spring 726.

  Further, the specific example shown in FIG. 11 also includes a toilet lid opening / closing detection unit 530 and a toilet seat opening / closing detection unit 534. That is, whether the toilet lid 400 or the toilet seat 410 is stopped is moving by detecting the rotation angle of the output shaft 728 by the angle detection unit 725 while detecting the rotation state of the motor 721 by the rotation detection unit 722A. And whether it is in an open state or a closed state, or at an angle between them.

Next, the operation of the heating toilet seat device of the present embodiment will be described with reference to a specific example.
FIG. 12 is a flowchart showing a first specific example of the operation of the heating toilet seat device of the present embodiment. First, in the standby state, warm air heating of the toilet seat 410 is performed with both the toilet lid 400 and the toilet seat 410 closed (step S102).
From this state, it is first determined whether or not the automatic opening / closing mode is on (step S104). If the auto open / close mode is on (step S104: yes), it is detected whether the user has entered the tray chamber (step S108). As described above with reference to FIG. 8, this is performed by the human body detection unit 520 (FIG. 8) provided in the casing 500, the remote controller 200, or a sensor unit that is grounded separately from these. Here, for example, when a pyroelectric sensor is used, it is possible to detect the user's entry into the room more quickly with high sensitivity.

  And if a user's entrance is detected (step S108: yes), the toilet lid electric opening / closing part 528 will be operated and the toilet lid 400 will be opened automatically (step S110). This is an operation based on the auto open / close mode.

  Next, it is determined whether or not the human body detection unit 520 detects a human body (step S112). An example of the sensor used here is an infrared light projection type sensor. Further, for example, a sensor for detecting a user in front of the toilet bowl 300 and a sensor for detecting a user sitting on the toilet seat 410 (sitting sensor) may be combined. That is, when at least one of these two sensors detects a human body, it is determined that a user exists.

  At this time, as described above, a pyroelectric sensor may be used as a sensor for detecting entry in step S108, and an infrared projection sensor may be used as a sensor for detecting a human body in step S112. The pyroelectric sensor is suitable for entry detection because it can quickly detect the approach of the user. On the other hand, whether or not the user is in the toilet room is more easily detected by the infrared light projection type sensor than by the pyroelectric sensor.

  For example, even if the pyroelectric sensor detects the user, when the infrared light projecting sensor does not detect the user sitting in front of the toilet bowl 300 or the toilet seat 410, the user may It may be determined that it has left and it may be determined as non-detection in step S112.

  While the human body detection unit 520 detects the human body (step S112: yes), it is determined whether or not the toilet seat 410 is in an open state (step S114). This corresponds to, for example, the user pressing the switch 240 (see FIG. 4) of the remote controller 200 or manually opening the toilet seat 410. The opening / closing state of the toilet seat 410 can be detected by the toilet seat opening / closing detection unit 534, and a specific example thereof can be the rotation detection unit 722A or the angle detection unit 725 described above with reference to FIG. When the toilet seat 410 is opened (step S114: yes), the hot air heating is stopped (step S116). And it is determined whether the human body detection part 520 has detected the human body (step S118).

Here, when the user finishes using the toilet and leaves the toilet room, the human body detection unit 520 enters a non-detection state (step S118: no). Then, after a predetermined time has elapsed, the toilet seat 410 and the toilet lid 400 are each electrically closed, warm air heating is resumed (step S120), and the process returns to step S106. This is an operation based on the auto open / close mode.
On the other hand, when the human body detection unit 520 is in a non-detection state in step S112, the toilet lid 400 is closed by the toilet lid electric opening / closing unit 528 after a predetermined time has elapsed (step S121), and the process returns to step S106. This is also an operation based on the automatic opening / closing mode. Even if the toilet seat 410 is already open at this time, the toilet seat 410 is closed simultaneously with the closing of the toilet lid 400.

A series of steps from step S108 to S121 described above is a process executed in a state where the automatic opening / closing mode is on. On the other hand, steps S122 to S134 are forcibly closing mode processes executed when the automatic opening / closing mode is prohibited.
That is, when the automatic opening / closing mode is off (step S106: no), it is first determined whether or not the switch for opening the toilet lid is turned on (step S122). This corresponds, for example, to the switch 238 described above with respect to FIG. When the switch is turned on (step S122: yes), the toilet lid electric opening / closing unit 528 is operated to automatically open the toilet lid 400 (step S123). On the other hand, when the switch for opening the toilet lid is not turned on (step S122: no), it is determined whether or not the toilet lid 400 is opened (step S124). The opening / closing state of the toilet lid 400 can be detected by the toilet lid opening / closing detection unit 530, and the rotation detection unit 722A and the angle detection unit 725 described above with reference to FIG. If the toilet lid 400 is not opened (step S124: no), the process returns to step S106.

  On the other hand, when the toilet lid 400 is open (step S124: yes), it is determined whether or not the human body detection unit 520 detects a human body (step S126). If the human body is not detected (step S126: no), it can be determined that the user has left the toilet room, and the process returns to step S106.

  On the other hand, when the human body is detected (step S126: yes), it is determined whether or not the toilet seat 410 is in an open state (step S128). This is as described above for step S114. And when the toilet seat 410 is opened (step S128: yes), warm air heating is stopped (step S130), and it is further determined whether the human body detection part 520 has detected the human body (step S132). .

When the user finishes using the toilet and leaves the toilet room, the human body detection unit 520 enters a non-detection state (step S132: no). Then, after elapse of a predetermined time, the toilet seat 410 and the toilet lid 400 are electrically closed, warm air heating is restarted (step S134), and the process returns to step S106.
As described above, according to this example, even when the automatic opening / closing mode is turned off, as described above with respect to steps S122 to 134, when the user leaves the toilet room, the toilet seat 410 is automatically set after a predetermined time. The hot air heating can be resumed. Therefore, the problem that the toilet seat 410 is left open and cooled down can be solved.

  FIG. 13 is a flowchart showing a second specific example of the operation of the heating toilet seat device of the present embodiment.

  Steps S102 to S132 in this specific example can be the same as those described above with reference to FIG. In this specific example, when the automatic opening / closing mode is off, if the human body is not detected in step S132 (step S132: no), the toilet lid 400 is electrically closed and hot air heating is resumed ( Step S202). That is, the toilet lid 400 is closed when the toilet seat 410 is open. Then, the toilet seat 410 is also closed simultaneously.

FIG. 14 is a schematic view illustrating an operation in which the toilet seat 410 is closed simultaneously by closing the toilet lid 400.
When the toilet lid 400 starts to close after the toilet lid 400 and the toilet seat 410 are opened as shown in FIG. 14A, the toilet lid 400 is pushed as shown in FIGS. 14B to 14D. The toilet seat 410 is also closed. When the toilet lid 400 and the toilet seat 410 are closed at the same time, the seat surface of the toilet seat 410 is always kept covered with the toilet lid 400, so that an effect of keeping heat by suppressing heat radiation from the toilet seat 410 is obtained. . That is, the temperature of the seat surface of the toilet seat 410 when the toilet seat 410 is closed and the warm air heating is restarted can be further increased.

  FIG. 15 is a flowchart showing a third specific example of the operation of the heating toilet seat device of the present embodiment.

  Steps S102 to S132 in this specific example can be the same as those described above with reference to FIG. Also, step S202 can be similar to that described above with respect to FIG.

  In this specific example, when the automatic opening / closing mode is off, if the human body is not detected in step S126 (step S126: no), the toilet lid 400 is electrically closed (step S204). That is, when the human body is not detected in the state where the toilet lid 400 is opened, the toilet lid 400 is automatically closed regardless of whether the toilet seat 410 is opened or closed. In this way, for example, the toilet lid 400 can be forcibly closed even when the user leaves the toilet room while the toilet lid 400 is opened and the toilet seat 410 remains closed. As a result, the surface of the toilet seat 410 that is warm-air heated can be covered with the toilet lid 400 and kept warm.
