FIG. 2 is a partially enlarged sectional view of the toilet seat of the toilet seat apparatus. The toilet seat 4 is formed of plastic or the like,
At least the top surface of the upper surface on which the buttocks of the human body directly touch is constituted by the heat insulating layer 12 made of a low heat conductive material. This low thermal conductive material is a foamed material obtained by foaming plastic such as polyethylene, polypropylene or urethane, rubber, etc., and has a small air layer and flexibility inside, such as soft foamed urethane foam and soft felt material. When the soft material is formed of a soft material, the soft material has cushioning properties, so that an elderly person or the like can feel comfortable even when sitting for a long time without feeling stiffness. In addition, in the method of heating from below, the heat insulation layer 12 is compressed by sitting down, the heat transfer distance is shortened, heat conduction from below is quickened, and the warmth is easily felt.

Further, the surface of the heat insulating layer 12 is covered with a protective layer 28.

The protective layer is a skin layer on the surface of the heat insulating layer 12, that is, a skin layer formed of a material having the same material and no foaming, or a hard layer formed by closely contacting a hard material made of polypropylene, ABS resin or the like in a thin film shape. is there. The thickness of the hard layer is 1 mm or less, preferably 0.1 mm or less. By doing so, the performance of the protection of the heat insulating layer 12 in the toilet environment such as water, detergent, scratches, warm air for heating and other anti-fouling and ease of cleaning is remarkably improved. As compared with the above, the durability and maintainability of the device are improved, and the comfort of the user is significantly improved.

Referring back to FIG. 1, when the user enters the toilet, the entry is detected by the human body detection device 29 and an entry signal is sent to the control means 30. The control means 30 drives the hot air generator 15 to supply hot air from the cover space hot air outlet 17 to the cover space 9 through the hot air supply pipe 18, function as a cover space hot air supply device, and operate the toilet seat 4. Is released from the gap 8 while heating the heat insulating layer 12. At this time, since the heat retaining layer 12 made of a low thermal conductive material on the upper surface of the toilet seat is heated from the surface, the surface temperature rises rapidly. At the same time, this part is in contact with the human body, and when the user raises the toilet seat lid and sits down on the toilet seat, the temperature has already been raised, and the feeling of cold does not occur. That is, in the present apparatus, when the room temperature is not so low (15 to 10 ° C. or more, depending on the state of the material), there is no cooling sensation without operating the hot air generator 15, but even when the room temperature is low (5 ° C. or less). By the short-time heating by the hot air generator 15, the heat retaining layer 12 can be quickly heated to a temperature at which a cool sensation is not felt, and a comfortable toilet seat device without a cold sensation can be provided. The hot air generator 15 is preferably stopped when the toilet seat lid 5 is raised, but may be used to warm the human body or heat the room without stopping.

As described above, when the toilet seat device is automatically operated by the human body detecting device 29, the user does not need to input a switch, and it is possible to avoid a situation in which the toilet seat becomes cold due to forgetting to turn on the switch and causes discomfort. It is possible to provide a toilet seat device with high user comfort.
Note that even if the user himself / herself operates a switch or the like to send an entry signal when entering the room, there is a time necessary for heating from entry to seating, so such a configuration may be employed. Further, according to the configuration of the present embodiment, it is not necessary to energize when not in use, so that standby power can be omitted, and energization only during the actual use time of the toilet is sufficient, so that a remarkable energy saving effect can be obtained.

If the user forgets to close the toilet seat cover 5 when getting out of the toilet, the toilet seat heating device does not work at the time of reuse. In order to prevent such a situation, when the human body detecting device 29 does not detect a human body and the toilet lid opening / closing detecting device 33 detects the open state of the toilet lid 5, a warning sound is sounded to alert the user. Alternatively, a toilet seat lid opening / closing device may be separately provided and automatically closed so that the toilet seat heating device operates.

In this embodiment, warm air is used to heat the heat insulating layer. However, only the surface needs to be heated. Therefore, a heater is provided at the place of the toilet seat lid 5 facing the lid space 9. It is also possible to provide a configuration in which heating is performed by radiant heat. At this time, air may be sent at the same time (warm air may be sent), and heating may be performed by radiant heat and convective heat transfer. further,

May be contacted and heated by heat transfer. Insulation layer 1
It is also conceivable that a heating means is provided in the heat insulating layer 12.
Any configuration that selectively heats the surface facing the lid space is included in the present invention.

(Embodiment 2) FIG. 3 is a partial sectional view of a toilet seat device according to a different embodiment of the present invention. Toilet seat 4
Is composed of a toilet seat body 2 and a bottom plate 3, and the interior is a toilet seat space 20. A toilet air outlet 21 is provided on the side surface of the toilet seat body 2. In the middle of the hot air supply pipe 18 connected to the hot air generator 15, there is a branch 19, and one of the branches of the branch 19 is connected to the toilet seat warm air outlet 21 that guides warm air into the toilet seat. , And functions as a toilet seat warm air supply device. Similarly to the first embodiment, the other branch is connected to a lid space hot air outlet 17 for guiding hot air to the lid space 9 and functions as a lid space hot air supply device. Note that components having the same reference numerals as those in the previous embodiment have the same structure, and description thereof will be omitted.

When using the toilet, when the entrance of the toilet is detected by the human body detecting device 29, the warm air generating device 15 is operated by the control means 30, and the hot air generating device 15 is branched into two at the branch portion 19, and the two are respectively connected to the lid space 9 and the lid space 9. It is supplied to the toilet seat space 20. The top surface 11 is quickly heated by the warm air supplied to the lid space 9, and in a short time from when a person enters the room to when the toilet seat lid 5 is opened and seated, to a temperature at which the user does not feel cold even when seated. It is rising. In addition, the air is gradually heated toward the top surface 11 by the warm air supplied to the toilet seat space 20. That is, the top surface 1
The cooling sensation at the time of sitting by the heating from 1 is prevented, and the warming from the inside increases with time due to the heating from the inside to function as a heating toilet seat.

When the toilet seat lid 5 is lifted, a shut-off valve 22 is provided between the branch portion 19 and the lid space hot air outlet 17 in order to stop the supply of hot air to the lid space hot air outlet 17. The closing valve 22 is interlocked with a toilet seat lid opening / closing detection device 33 provided at a rotating portion of the support shaft 13 or the like.
When the toilet lid 5 is opened, the toilet lid opening / closing detecting device 33 detects that the toilet lid is opened, sends a signal for closing the closing valve 22, and controls the capability of the hot air generator at the same time. By doing so, the warm air heats only the toilet seat 4 from the inside by a required amount, so that waste of energy can be prevented.

As in the first embodiment, if a thin heat insulating layer 12 made of a low heat conductive material is formed on the top surface 11 of the toilet seat 4, the thermal conductivity of the seating portion on the toilet seat surface can be reduced. The amount of heat taken from the buttocks to the toilet seat 4 when sitting on the toilet seat 4 can be reduced. This makes it more difficult for the user to feel a cold sensation, and the temperature rise of the surface of the heat-retaining layer 12 by heating with hot air is quickened.

Alternatively, the shut-off valve 22 may be omitted, and the warm air may be blown directly into the room at the time of use to use the room for room heating. Furthermore, even when the hot air is completely stopped during use,
The warm air blown out in advance stays in the toilet seat space 20,
The present invention also includes a configuration in which heating from the toilet seat space 20 to the top surface 11 is continued, and the warming increases with time to function as a heating toilet seat.

(Embodiment 3) FIG. 4 is a partial sectional view of a toilet seat device according to another embodiment of the present invention.
FIG. 5 is a partially enlarged sectional view of a toilet seat portion of the toilet seat device. The toilet seat space 20 is configured as a closed space by the toilet seat body 2 and the bottom plate 3, and the heat conductive sheet 23 is provided on the back side of the top surface 11 of the space 20.
The toilet seat heater 24 is formed in close contact with the heater, and a heat insulating layer 25 made of a heat-resistant material such as fiber or felt is provided below the toilet seat heater 24. With this configuration, the heat of the toilet seat heater 24 that is energized is prevented from being lost downward by the heat insulating layer 25, and the top surface 11 of the upper toilet seat can be heated to increase energy efficiency. Here, even if the heat insulating layer 25 is not provided, the heat can be transmitted well if it is brought into close contact with the heat conductive sheet 23, so that there is a slight loss of heat. Note that components having the same reference numerals as those in the previous embodiment have the same structure, and description thereof will be omitted.

The toilet seat heater 24 is always energized with low electric power, but is set to a low temperature at which a cool sensation is felt when sitting. At this time, when the user enters the room,
This is detected by the human body detection device 29 and a signal is sent to the control means 30. The control means 30 increases the electric power of the toilet seat heater 24 and drives the hot air supply device 15. The toilet seat temperature is set so as to heat to a set temperature at the time of use (optimum around 40 ° C.). By doing so, the toilet seat top surface 11 is immediately heated to the set temperature or at least to a temperature at which the user does not feel cold (31 ° C. or more) before the user opens the toilet seat lid and uses it. Therefore, the user does not feel cold when using.

When the user exits the toilet after use, the human body detecting device 29 detects that the user has left the toilet and sends a signal to the control means 30. The control device 30 includes the toilet seat heater 2
Keep the power of 4 low. For example, it is sufficient to set the toilet seat temperature at 15 to 20 ° C. At this time, the hot air supply device 15 is stopped.

When the user enters the room again to use the toilet, the power of the toilet seat heater 24 is increased by the detection signal from the detection device 29 and the hot air supply device is driven to heat the set temperature.

That is, when not in use, the electric power of the toilet seat heater 24 is reduced, and a cool sensation is felt if the user sits down.
When a person is detected, the power of the toilet seat heater 24 is increased, and the hot air supply device is driven to rapidly heat the toilet seat top surface 11. This prevents an initial cold sensation and ensures toilet seat heating.

At this time, in the conventional toilet seat device, the energy saving ratio is such that the set temperature during standby is 30 ° C. (sometimes 40 ° C.).
° C), but according to the present invention, the set temperature is 15 to
Since the temperature can be set to 20 ° C., if the average temperature during the period of using the toilet seat heating is set to 10 ° C., there is a significant reduction effect of 50 to 75% (65 to 80%).

When the heat-insulating layer 12 made of a low heat conductive material is provided on the toilet seat top 11, it is possible to make the sensation of cooling sensation difficult and to make the heating rise quickly. Can be configured.

In the operation of the present embodiment, the following can be performed. When the user enters the room, it is detected by the human body detection device 29 and a signal is sent to the control means 30. The control means 30 increases the electric power of the toilet seat heater 24 and drives the hot air supply device 15. The toilet seat temperature is set so as to heat to a set temperature at the time of use (optimum around 40 ° C.). In this way, the toilet seat top surface 11 is quickly heated to at least a temperature (31 ° C. or higher) at which the user does not feel a cool sensation before the user opens the toilet seat lid and uses the toilet seat top 11 during use. The user does not feel cold when using.

When the user has left the toilet after use, the detection is sent to the control means 30 by the human body detecting device 29. The control device 30 stops the toilet seat heater input and the hot air input.

Then, when the user enters the room again for using the toilet, the power of the toilet seat heater 24 is increased by the detection signal from the detection device 29, and the hot air supply device is driven to heat the set temperature.

Therefore, only during use, the toilet seat heater 24 and the hot air supply device are driven to rapidly heat the toilet seat top surface 11. This prevents an initial cold sensation and ensures toilet seat heating.

In this case, since there is no need to constantly supply power, the energy saving effect is very large.

(Embodiment 4) FIG. 6 is a partial sectional view of a toilet seat of a toilet seat apparatus according to a different embodiment of the present invention.
In the toilet seat 4, a toilet seat space 20 is formed by the toilet seat body 2 and the bottom plate 3, and a plurality of pores 26 are formed on the top surface 11.
Further, the toilet seat lid 5, the flange 6, and the projection 7 that cover the toilet seat from above form a lid space 9 with the toilet seat 4, and at the same time, the lower ends of the flange 6 and the projection 7 are below the air holes 26. It is configured as follows. Therefore, the pores 26 face the lid space 9. The hot air generator 15 is connected to a hot air supply pipe 18,
Furthermore, it is connected to the toilet seat space 20 through the toilet air outlet 21. Further, a heat insulating layer 12 is provided on the surface of the toilet seat 4. The door of the toilet is provided with a door opening / closing detection device 31 to send a signal to the control device 30. The control device 30 controls the operation of the hot air generator 15.

When the user opens the toilet door, the door opening / closing detecting device 31 detects the opening and sends a signal to the control device 30. The control device 30 drives the hot air generating device 15, and the hot air supplied from the hot air generating device 15 is blown out to the toilet seat space 20, and is blown out from the pores 26 while heating the toilet seat 4 from the inside. The heat is released from the gap 8 into the room through the space 20 while heating the heat insulating layer 12 on the side wall and the top surface. Therefore, the thermal insulation layer 12 on the top surface of the toilet seat 4
Is heated from the surface and heated for a short time from when the user enters the room to when the toilet seat lid 4 is opened, and the temperature rises rapidly, reaches a temperature at which the user does not feel cold, and provides a comfortable toilet seat device with a simple configuration. Can be configured.

When the door opening / closing detecting device 31 detects that the toilet door has been opened, the time during which the hot air generating device 15 is driven is set to, for example, about 10 seconds. Judging that the toilet door is open or that a man is urinating, stops the generation of warm air. The seating detection of the user may be performed by the seating detecting means 32, for example.
When a man urinates, the toilet seat is also raised, so that it may be configured to detect this and stop the warm air.

If the generation of warm air is continued even when the toilet seat lid 5 is used, the heating is continued from the inside of the toilet seat 4, and the warm air hits the buttocks and thighs from the pores 26. Therefore, it also works as local heating, and the effect that the user does not feel cold even when the indoor temperature is lowered can be obtained. If the pores 26 are placed in a place where they are closed by the buttocks and thighs of the user, warm air is not blown out of the pores 26 during use, so that energy saving is high. When the use is completed and the user stands up, this is detected by the seating detecting means, and the generation of warm air is stopped. Thereafter, when the user comes out of the toilet, the door opening / closing detection device 31 detects that the door has been opened.
If the signal indicating that the door opening / closing detection device 31 is opened is ignored for about 10 seconds after the start is detected, useless blowing of warm air is eliminated.

If the user forgets to close the toilet lid from (Embodiment 2) to (Embodiment 4), similarly to (Embodiment 1), the toilet lid opening / closing detecting device and the human body The detection device or the door opening / closing detection device detects this and sounds a warning sound, and a toilet seat cover opening / closing device may be separately provided to automatically close the toilet seat opening / closing device.
