DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals and detailed description thereof will be omitted as appropriate. FIG. 1 is a perspective view showing a toilet device according to an embodiment. As shown in FIG. 1, the toilet apparatus 100 is installed above a toilet bowl 200.

[0010] The toilet 200 is a so-called seated toilet. The toilet 200 has a bowl portion 201 that is recessed downward. The toilet 200 receives excrement such as urine and feces from the user in the bowl portion 201.

[0011] The toilet device 100 comprises a casing 10, a toilet lid 20, and a toilet seat 30. In this specification, the terms "upper," "lower," "front," "rear," "right side," and "left side" refer to directions seen from a user sitting on the toilet seat 30 with their back to the open toilet lid 20.

[0012] The casing 10 is provided on top of the rear of the toilet bowl 200. The casing 10 has a case plate 11 located at the bottom, and a case cover 12 that covers the upper part of the case plate 11. The casing 10 incorporates functional units inside the space formed between the case plate 11 and the case cover 12. The functional units include, for example, a toilet lid opening and closing unit 40, a toilet seat opening and closing unit 50, a control unit 60, a nozzle unit 71, a valve unit 72, a deodorizing unit 73, and a fan unit 80, which will be described later.

[0013] The toilet lid 20 is pivotally supported by a toilet lid opening / closing unit 40 (see FIG. 2) provided inside the casing 10, thereby allowing it to rotate relative to the casing 10. The toilet seat 30 is pivotally supported by a toilet seat opening / closing unit 50 (see FIG. 2) provided inside the casing 10, thereby allowing it to rotate relative to the casing 10. When closed, the toilet lid 20 covers the top of the toilet seat 30. Figure 1 shows the toilet lid 20 in an open state, and the toilet seat 30 in a closed state.

[0014] The toilet lid 20 has a toilet lid body 21 and a hinge portion 22. When the toilet lid body 21 is closed, it is located above the toilet seat 30. When the toilet lid 20 is closed, the hinge portion 22 is located behind the toilet lid body 21.

[0015] The toilet seat 30 has a seating portion 31 and a hinge portion 32. When the toilet seat 30 is closed, the seating portion 31 is located above the bowl portion 201 of the toilet bowl 200. The seating portion 31 is the portion on which a user sits. When the toilet seat 30 is closed, the hinge portion 32 is located behind the seating portion 31.

[0016] Thus, the toilet apparatus 100 has two opening and closing bodies, the toilet lid 20 and the toilet seat 30, which are opened and closed by rotating relative to the casing 10. In this embodiment, the toilet lid 20 is used as the opening and closing body.

[0017] FIG. 2 is a plan view that shows a schematic view of the inside of a casing of the toilet device. FIG. 3 is an enlarged plan view showing the toilet lid opening / closing unit, the toilet seat opening / closing unit, and the fan unit in FIG. Fig. 4 is a cross-sectional view of the toilet lid motor of the toilet lid opening and closing unit and the toilet seat motor and fan unit of the toilet seat opening and closing unit as viewed from the direction of the arrow AA in Fig. 3. In Fig. 4, the deodorizing unit is omitted. FIG. 5 is an explanatory diagram illustrating the relationship between the first air inlet of the fan unit and the toilet lid motor.

[0018] FIG. 2 shows the casing 10 with the case cover 12 removed. As shown in FIG. 2, inside the casing 10, a toilet lid opening and closing unit 40, a toilet seat opening and closing unit 50, a control unit 60, a nozzle unit 71, a valve unit 72, a deodorizing unit 73, and a fan unit 80 are provided.

[0019] The toilet lid opening / closing unit 40 is provided on the left side at the rear of the casing 10. The toilet lid opening / closing unit 40 pivotally supports the toilet lid 20 and electrically opens and closes the toilet lid 20. The toilet lid opening / closing unit 40 has a toilet lid motor 41 and a toilet lid transmission mechanism 42. As shown in Figures 2 and 3, the toilet lid opening / closing unit 40 is arranged so that the toilet lid motor 41 and the toilet lid transmission mechanism 42 extend in a straight line in the left-right direction.

[0020] The toilet lid motor 41 provides a driving force for opening and closing the toilet lid 20. In this embodiment, the toilet lid motor 41 serves as an opening and closing motor. The toilet lid transmission mechanism 42 has a base end connected to the toilet lid motor 41 and a tip end connected to the hinge portion 22 of the toilet lid 20. The toilet lid transmission mechanism 42 has, for example, a reduction mechanism, and transmits the driving force of the toilet lid motor 41 to the hinge portion 22 of the toilet lid 20.

[0021] The toilet seat opening / closing unit 50 is provided in front of the toilet lid opening / closing unit 40. The toilet seat opening / closing unit 50 axially supports the toilet seat 30 and electrically opens and closes the toilet seat 30. The toilet seat opening / closing unit 50 has a toilet seat motor 51 and a toilet seat transmission mechanism 52. As shown in Figures 2 and 3, the toilet seat opening / closing unit 50 is arranged so that the toilet seat motor 51 and the toilet seat transmission mechanism 52 extend in a straight line in the left-right direction.

[0022] The toilet seat motor 51 provides a driving force for opening and closing the toilet seat 30. In this example, the toilet seat motor 51 is a second motor for electrically opening and closing the toilet seat 30. The toilet seat transmission mechanism 52 has a base end connected to the toilet seat motor 51 and a tip end connected to the hinge portion 32 of the toilet seat 30. The toilet seat transmission mechanism 52 has, for example, a speed reduction mechanism, and transmits the driving force of the toilet seat motor 51 to the hinge portion 32 of the toilet seat 30.

[0023] In Fig. 2, for convenience of explanation, the toilet lid opening / closing unit 40 and the toilet seat opening / closing unit 50 are arranged on the case plate 11, but the toilet lid opening / closing unit 40 and the toilet seat opening / closing unit 50 are each fixed to the case cover 12. In addition, the toilet lid opening / closing unit 40 and the toilet seat opening / closing unit 50 may each be fixed to the case plate 11.

[0024] The control unit 60 is provided on the right side of the case plate 11. In other words, the control unit 60 is provided on the opposite side of the fan unit 80 from the toilet lid opening / closing unit 40 and the toilet seat opening / closing unit 50. The control unit 60 controls the opening and closing operations of the toilet lid 20 and the toilet seat 30. The control unit 60 is connected to the toilet lid motor 41 and the toilet seat motor 51 by a harness (not shown). The control unit 60 controls the operation of the toilet lid motor 41 and the toilet seat motor 51 based on control signals transmitted from, for example, a remote control or a human body detection sensor that detects a human body located in front of the toilet device 100 (neither of which are shown).

[0025] The nozzle unit 71 sprays water toward the private parts of the user seated on the toilet seat 30 to clean the private parts. The nozzle unit 71 has, for example, a nozzle that sprays water and a nozzle motor (neither shown) that moves the nozzle forward or backward. The nozzle unit 71 cleans the private parts of the human body by spraying water from the nozzle while the nozzle is advanced into the bowl portion 201 of the toilet 200. The nozzle unit 71 may further have a nozzle cleaning chamber for cleaning the nozzle. In this example, the nozzle unit 71 is provided between the control unit 60 and the toilet lid opening and closing unit 40 and between the control unit 60 and the toilet seat opening and closing unit 50 in the left-right direction.

[0026] The valve unit 72 supplies water supplied from a water supply source outside the casing 10 via a water supply hose (not shown) or the like to the nozzle unit 71. The valve unit 72 has, for example, a solenoid valve for controlling the supply of water to the nozzle unit 71, a pressure regulating valve for adjusting the pressure, and a check valve for preventing backflow (none of which are shown). For example, a heat exchanger unit, an electrolytic cell unit, a vacuum breaker (none of which are shown), and the like are provided between the valve unit 72 and the nozzle unit 71. In this example, the valve unit 72 is provided in front of the control unit 60.

[0027] The deodorizing unit 73 sucks in and deodorizes the air within the bowl portion 201 of the toilet 200. The deodorizing unit 73 has, for example, a deodorizing section that reduces odors, and a fan for blowing air (neither shown). In this example, the deodorizing unit 73 is provided below the toilet lid opening / closing unit 40 and the toilet seat opening / closing unit 50.

[0028] In addition to controlling the toilet lid opening / closing unit 40 (toilet lid motor 41) and the toilet seat opening / closing unit 50 (toilet seat motor 51), the control unit 60 also controls, for example, the nozzle unit 71, the valve unit 72, and the deodorizing unit 73. Note that the nozzle unit 71, the valve unit 72, and the deodorizing unit 73 may be controlled by a control unit separate from the control unit 60.

[0029] The fan unit 80 is provided inside the casing 10 and blows out hot air to the outside of the casing 10. The fan unit 80 is a hot air drying unit that blows hot air toward, for example, the inside of the bowl portion 201 of the toilet 200, thereby drying the private parts of the body of a user seated on the toilet seat 30. The fan unit 80 is provided in the left-right direction between the nozzle unit 71 and the toilet lid opening / closing unit 40 and the toilet seat opening / closing unit 50. The fan unit 80 operates based on a control signal transmitted, for example, from a remote control.

[0030] The fan unit 80 has a housing 82 and a fan motor 84 housed inside the housing 82. The fan unit 80 also has a heating section 86 inside the housing 82 that heats the sucked air. The fan unit 80 is connected to the control section 60, and switches between blowing out hot air and stopping the blowing of hot air in response to a control signal transmitted from the control section 60.

[0031] The housing 82 is disposed so as to extend in the front-rear direction inside the casing 10. The housing 82 has a first air intake port 82a for drawing air F1 inside the casing 10 into the housing by operation of a fan motor 84, a second air intake port 82b provided at a position different from the first air intake port 82a and for drawing air F2 inside the casing 10 into the housing, an air guide passage 82c communicating with the first air intake port 82a and the second air intake port 82b, and an outlet 82d provided downstream of the air F3 flowing through the air guide passage 82c.

[0032] The first air intake port 82a is formed on the rear side of the left side surface of the housing 82 and opens toward the left side. In other words, the first air intake port 82a opens toward the toilet lid motor 41 of the toilet lid opening / closing unit 40. The positional relationship between the first air intake port 82a and the toilet lid motor 41 will be explained later.

[0033] On the other hand, the second intake port 82b is formed at a position different from the first intake port 82a. The second intake port 82b faces the first intake port 82a in the left-right direction. That is, the second intake port 82b is formed on the rear side of the right side surface of the housing 82 and opens toward the right side. In other words, the second intake port 82b opens toward the nozzle unit 71 and the control unit 60.

[0034] The air guide passage 82c extends in the front-rear direction inside the housing 82. Specifically, the air guide passage 82c communicates with the first air intake port 82a and the second air intake port 82b on the upstream side in the flow direction of the air F3 and extends toward the front side. The outlet 82d is provided at the downstream end of the air F3 flowing through the air guide passage 82c. A heating unit 86 that heats the air F3 is provided in the middle of the air guide passage 82c.

[0035] The fan motor 84 is located on the upstream side of the air guide passage 82c and is provided between the first air intake port 82a and the second air intake port 82b. The fan motor 84 is, for example, a sirocco fan, and is controlled by the control unit 60.

[0036] The fan unit 80, by operating the fan motor 84, draws air F1, F2 inside the casing 10 into the housing 82 through the first intake port 82a and the second intake port 82b. The air F3 drawn into the housing 82 is heated by a heating section 86 provided in the air guide passage 82c. The heating section 86 has a heater and a temperature sensor (neither shown). The heating section 86 is connected to the control section 60, which controls the temperature of the air F3 in the air guide passage 82c. The air F3 flowing through the air guide passage 82c is then ejected from the ejection port 82d toward the bowl section 201. In this way, the fan unit 80 dries the user's body parts that have become wet during washing.

[0037] Next, the positional relationship between the toilet lid motor 41 of the toilet lid opening and closing unit 40 and the fan unit 80 will be described. FIG. 5 is an explanatory diagram illustrating the relationship between the first air inlet of the fan unit and the toilet lid motor.

[0038] First, when the toilet device 100 is used frequently, for example, the toilet lid 20 is frequently opened and closed due to human body detection by the human body detection sensor. If the toilet lid 20 is repeatedly opened and closed electrically, there is a risk that the torque will decrease due to an increase in temperature of the toilet lid motor 41. This may affect the opening and closing operation of the toilet lid 20.

[0039] Therefore, in this embodiment, the toilet lid motor 41 is arranged next to the first air intake 82a in the left-right direction. In this case, as shown in FIG. 5, at least a portion of the toilet lid motor 41 is arranged on the projection plane P of the first air intake 82a of the fan unit 80. The projection plane P of the first air intake 82a is the plane when the first air intake 82a is projected in the opening direction. That is, as shown in FIG. 4, at least a portion of the toilet lid motor 41 overlaps with the first air intake 82a when the first air intake 82a is viewed from the front.

[0040] As a result, as shown in Figure 3, the air F1 inside the casing 10 comes into contact with the toilet lid motor 41 and is then guided to the first air intake 82a. The toilet lid motor 41 is cooled by coming into contact with the air F1 flowing toward the first air intake 82a. In other words, the air F1 flowing toward the first air intake 82a serves as cooling air that cools the toilet lid motor 41. Therefore, even if the toilet lid 20 is frequently opened and closed, the torque reduction caused by the temperature rise of the toilet lid motor 41 can be suppressed, and the impact on the opening and closing operation of the toilet lid 20 can be reduced.

[0041] In addition, the air F1 has absorbed heat from the toilet lid motor 41, and thus its temperature has increased when it is introduced into the air guide passage 82c from the first air intake port 82a. This allows the fan unit 80 to keep the amount of heat required to increase the temperature of the air F3 in the heating section 86 low. As a result, the power consumption of the fan unit 80 can be reduced.

[0042] As shown in Figures 3 and 5, the toilet lid motor 41 is arranged with its longitudinal direction (the direction of the arrow BB in Figure 5) horizontal. The first air intake 82a opens toward the longitudinal direction of the toilet lid motor 41. This allows air F1 to flow toward the first air intake 82a along the longitudinal direction of the toilet lid motor 41, as shown in Figure 3. This allows the contact area between the toilet lid motor 41 and the air F1 to be increased, so that the toilet lid motor 41 can be cooled efficiently and the temperature of the air F1 introduced into the housing 82 of the fan unit 80 can be efficiently increased.

[0043] 4, it is preferable that more than half of the toilet lid motor 41 overlaps with the first air intake 82a when viewed from the front. This allows more air F1 to come into contact with the toilet lid motor 41, so that the toilet lid motor 41 can be cooled more efficiently and the temperature of the air F1 introduced into the housing 82 of the fan unit 80 can be increased more efficiently.

[0044] In addition, by making the overlap between the toilet lid motor 41 and the first air intake 82a as large as possible, it is possible to reduce the height difference between the fan unit 80 and the toilet lid motor 41. This allows the height dimension of the casing 10 to be reduced, resulting in a toilet apparatus 100 with a good appearance.

[0045] As shown in Figures 2 and 3, the toilet lid motor 41 is disposed within dimension L1 from the first air intake 82a. In this case, dimension L1 is the distance (shortest distance) from the first air intake 82a to the toilet lid motor 41. The dimension L1 between the toilet lid motor 41 and the first air intake 82a can be set by experiment and simulation, taking into consideration the performance of the fan motor 84, the cooling efficiency of the toilet lid motor 41, etc.

[0046] This dimension L1 can be set, for example, between 0 mm and 20 mm (0 mm≦L1≦20 mm). By placing the toilet lid motor 41 as close as possible to the first air intake 82a, the toilet lid motor 41 can be cooled efficiently.

[0047] However, if dimension L1 is set to 0 mm, the toilet lid motor 41 will block the first air intake 82a. Therefore, it is preferable that the toilet lid motor 41 is placed at a distance from the first air intake 82a. In this case, it is preferable that no other members exist between the toilet lid motor 41 and the first air intake 82a. In other words, dimension L1 is the dimension of the gap between the toilet lid motor 41 and the first air intake 82a.

[0048] As a result, since the lid motor 41 does not block the first air inlet 82a, a large amount of air F1 can be introduced from the first air inlet 82a into the air guide path 82c, and a decrease in the air volume of the fan unit 80 can be suppressed.

[0049] Next, the housing 82 of the fan unit 80 has a second air inlet 82b at a position different from the first air inlet 82a. That is, the second air inlet 82b introduces the air F2 into the air guide path 82c from a direction different from that of the first air inlet 82a. As shown in FIG. 3, the second air inlet 82b faces the first air inlet 82a in the left-right direction, for example.

[0050] As a result, the second air inlet 82b introduces the air F2 into the housing 82 from the direction opposite to that of the first air inlet 82a by the operation of the fan motor 84. Therefore, even if the lid motor 41 approaches the first air inlet 82a, the fan unit 80 can secure the air volume (air F3) by the second air inlet 82b.

[0051] Further, the second air inlet 82b is preferably open toward the control unit 60. In this case, as shown in FIG. 2, the dimension L1 from the first air inlet 82a to the lid motor 41 is smaller than the dimension L2 from the second air inlet 82b to the control unit 60 (L1 < L2). The dimension L2 is the shortest distance from the second air inlet 82b to the control unit 60.

[0052] As a result, the air F2 in the casing 10 is introduced into the housing 82 from the second air inlet 82b after cooling the control unit 60 and other devices arranged in the opening direction of the second air inlet 82b. Therefore, the influence of the heat of the control unit 60 and other devices can be reduced. Further, since the second air inlet 82b can introduce the air F2 that has absorbed the heat of the control unit 60 and other devices into the air guide path 82c, the power consumption of the fan unit 80 can be reduced.

[0053] In addition, the toilet seat motor 51 is aligned in the front-to-rear direction with the toilet lid motor 41. Specifically, as shown in Fig. 4, at least a portion of the toilet seat motor 51 is located between the upper end (straight line CC shown by a dashed line) and the lower end (straight line DD shown by a dashed line) of the toilet lid motor 41. It is preferable that more than half of the toilet seat motor 51 is located between the upper end and the lower end of the toilet lid motor 41.

[0054] 3, even if the toilet seat motor 51 is positioned away from the projection plane P of the first air intake port 82a, the air F1 can be circulated along the longitudinal direction of the toilet seat motor 51. Therefore, the air F1 flowing toward the first air intake port 82a can cool the toilet seat motor 51 in addition to the toilet lid motor 41.

[0055] FIG. 6 is an explanatory diagram illustrating the relationship between the first air intake port of the fan unit of the toilet apparatus according to the first modified example and the toilet lid motor. In the above-described embodiment, an example has been described in which the fan unit 80 is arranged alongside the toilet lid motor 41 in the left-right direction, and the first air intake 82a of the fan unit 80 opens toward the longitudinal direction of the toilet lid motor 41. However, the present invention is not limited to this, and for example, as in a first modified example shown in Fig. 6, the first air intake 90a of the fan unit 90 may be positioned in front of the toilet lid motor 41. In other words, the first air intake 90a may be positioned in the front-rear direction perpendicular to the longitudinal direction of the toilet lid motor 41 (the direction of the arrow BB in Fig. 6).

[0056] FIG. 7 is an explanatory diagram illustrating the relationship between a first air intake port of a fan unit of a toilet apparatus according to a second modified example and a toilet lid motor. In the above-described embodiment, an example has been described in which the toilet lid motor 41 and toilet lid transmission mechanism 42 of the toilet lid opening / closing unit 40 are aligned in a straight line in the left-right direction. However, the present invention is not limited to this, and for example, as in a second modified example shown in Fig. 7, the toilet lid opening / closing unit 92 may have the toilet lid motor 93 in a longitudinal direction (the direction of the arrow EE in Fig. 7) perpendicular to the toilet lid transmission mechanism 94. In other words, the toilet lid opening / closing unit 92 may have an overall L-shape formed by the toilet lid motor 93 and the toilet lid transmission mechanism 94.

[0057] FIG. 8 is an explanatory diagram illustrating the relationship between the first air intake port of the fan unit of the toilet apparatus according to the third modified example and the toilet lid motor. 8, the fan unit 90 of the first modified example and the toilet lid opening / closing unit 92 of the second modified example may be used. In this case, the first air intake 90a of the fan unit 90 is open toward the longitudinal direction of the toilet lid motor 93, so that the toilet lid motor 93 can be cooled efficiently.

[0058] In the above embodiment, an example was described in which the opening / closing body was the toilet lid 20 and the opening / closing motor was the toilet lid motor 41. However, the present invention is not limited to this, and for example, the opening / closing body may be a toilet seat and the opening / closing motor may be a toilet seat motor. That is, at least a portion of the toilet seat motor may be disposed on the projection plane of the first air intake of the fan unit. Also, at least a portion of the toilet lid motor and at least a portion of the toilet seat motor may both be disposed on the projection plane of the first air intake of the fan unit.

[0059] Also, in the above-described embodiment, an example has been described in which the fan unit 80 is a warm air drying unit that dries the body parts of a user seated on the toilet seat 30. However, the present invention is not limited to this, and for example, the fan unit may be another device that draws in air inside the casing 10, such as an indoor heating unit that heats the toilet room.

[0060] In the above-described embodiment, the second air intake port 82b of the fan unit 80 is provided on the right side surface of the housing 82. However, the present invention is not limited to this, and the second air intake port may be provided on the rear surface or top surface of the housing, for example.

[0061] As a toilet apparatus based on the embodiment described above, for example, the following aspects are conceivable.

[0062] The first aspect is a toilet device installed on a toilet bowl, comprising a casing, an opening / closing body that can be opened and closed by rotating relative to the casing, an opening / closing motor provided within the casing for electrically opening and closing the opening / closing body, a control unit for controlling the operation of the opening / closing motor, and a fan unit provided within the casing for blowing warm air to the outside of the casing, wherein the opening / closing body is one of a toilet lid and a toilet seat, the fan unit has a housing and a fan motor housed inside the housing, the housing has a first air intake port for drawing air inside the casing into the interior by operation of the fan motor, and at least a portion of the opening / closing motor is arranged on the projection plane of the first air intake port.

[0063] According to the first aspect, the air inside the casing is guided to the first intake port after coming into contact with the opening / closing motor. Therefore, the opening / closing motor can be cooled by the air flowing toward the first intake port. Also, the air flowing toward the first intake port absorbs heat from the opening / closing motor, and the temperature increases. This makes it possible to reduce the temperature difference of the air raised by the fan unit, thereby reducing power consumption.

[0064] A second aspect is a toilet device according to the first aspect, characterized in that the opening / closing motor is arranged with its longitudinal direction horizontally, and the first air intake port opens toward the longitudinal direction of the opening / closing motor.

[0065] According to the second aspect, air can be circulated toward the first air intake port along the longitudinal direction of the opening-closing motor, and therefore the contact area between the opening-closing motor and the air can be increased, so that the opening-closing motor can be efficiently cooled and the temperature of the air introduced into the fan unit can be efficiently increased.

[0066] A third aspect is a toilet device according to the first or second aspect, characterized in that more than half of the opening / closing motor overlaps with the first air intake port when viewed from the front.

[0067] According to the third aspect, a larger amount of air can be brought into contact with the opening / closing motor, so that the opening / closing motor can be cooled more efficiently and the temperature of the air introduced into the fan unit can be increased more efficiently.

[0068] A fourth aspect is the toilet device according to any one of the first to third aspects, characterized in that the opening / closing motor is disposed within 20 mm from the first air intake port.

[0069] According to the fourth aspect, by placing the opening / closing motor as close as possible to the first air intake port, the opening / closing motor can be cooled more efficiently and the temperature of the air introduced into the fan unit can be increased more efficiently.

[0070] A fifth aspect is the toilet apparatus according to the fourth aspect, characterized in that the opening / closing motor is disposed at a distance from the first air intake port.

[0071] According to the fifth aspect, since the opening / closing motor does not block the first air intake port, a decrease in the air volume of the fan unit can be suppressed.

[0072] A sixth aspect is the toilet apparatus according to any one of the first to fifth aspects, characterized in that the housing has a second air intake at a position different from the first air intake.

[0073] According to the sixth aspect, a sufficient air volume of the fan unit can be ensured by the second air intake port.

[0074] A seventh aspect is a toilet device according to the sixth aspect, characterized in that the second air intake opens toward the control unit, and the dimension from the first air intake to the opening / closing motor is smaller than the dimension from the second air intake to the control unit.

[0075] According to the seventh aspect, the control unit can be cooled by the air flowing toward the second air intake. Also, the air flowing toward the second air intake absorbs heat in the control unit and the temperature rises, so the power consumption of the fan unit can be further reduced. Also, since the dimension from the first air intake to the opening / closing motor is smaller than the dimension from the second air intake to the control unit, the opening / closing motor, which is prone to dissipate a large amount of heat, can be effectively cooled.

[0076] An eighth aspect is the toilet apparatus according to any one of the first to seventh aspects, characterized in that the opening / closing body is the toilet lid, and the opening / closing motor is a toilet lid motor.

[0077] According to the eighth aspect, the toilet lid motor of the toilet lid, which is opened and closed more frequently than the toilet seat, can be cooled efficiently.

[0078] A ninth aspect is a toilet device according to the eighth aspect, further comprising a toilet seat motor provided within the casing for electrically opening and closing the toilet seat, at least a portion of the toilet seat motor being located between the upper and lower ends of the toilet lid motor.

[0079] According to the ninth aspect, even if the toilet seat motor is off the projection plane of the first air intake, the air flowing toward the first air intake can easily come into contact with the toilet seat motor. Therefore, both the toilet lid motor and the toilet seat motor can be efficiently cooled.
