Hereinafter, the same or equivalent constituent elements and components shown in the respective drawings are denoted by the same reference numerals, and overlapping description thereof will be omitted as appropriate. Further, the dimensions of the components in the drawings are appropriately enlarged or reduced for easy understanding. In the drawings, parts that are not important in the description of the embodiments are omitted. In the present specification, "up", "down", "left" and "right" respectively mean up, down, left and right seen from a user who uses the dressing table. Further, "front" and "rear" are the front side and the back side, respectively, as viewed from the user.
Fig. 1 is a perspective view of a toilet system using a toilet device 10 according to an embodiment. Fig. 2 is a perspective view of the toilet seat unit 16 and the case 20. The toilet system 1 includes a toilet device 10 installed in a toilet (toilet room) and a remote control device 8 installed on a wall surface of the toilet room. The remote control device 8 includes a plurality of input units 8a and a display unit 8 b. The input unit 8a includes a button for starting and stopping the toilet seat back surface cleaning, a button for opening and closing a toilet seat 22 (described later), and the like.
The toilet device 10 includes a toilet main body 14, a toilet seat unit 16, and a case 20. The toilet main body 1 includes a substantially funnel-shaped toilet bowl 12 for receiving waste, and an outer peripheral wall portion 13 for enclosing an outer peripheral side of the toilet bowl 12 and a toilet drain channel, not shown, so as to conceal them. The tank 20 is provided above the rear portion of the toilet main body 14. Various components are housed in the case 20.
The toilet seat unit 16 includes a toilet seat 22, a toilet cover 24, a flapper 38, and a toilet seat opening/closing motor 40. In the description of the toilet seat unit 16, the direction is indicated with reference to the closed toilet seat 22.
The toilet seat 22 is rotatably attached to the cabinet 20 via a hinge mechanism not shown. The toilet seat 22 is formed in an annular shape as a whole, and has a central opening 32 through which dirt excreted by a seated user passes. The toilet seat 22 is formed to be hollow, and at least one functional component is housed therein. The functional component is a component that is used by being attached to the toilet main body 14 and that performs a predetermined function. In this example, three functional components, namely, the private parts washing device 26, the drying device 28, and the deodorizing device 30, are housed behind the central opening 32.
An opening 36 for communicating the inside and outside of the toilet seat 22 is formed on the rear surface of the toilet seat 22 behind the central opening 32. The shutter 38 is configured to be able to open and close the opening 36. When the private parts washing device 26, the drying device 28, and the deodorizing device 30 are operated, the opening 36 is opened.
The private parts washing apparatus 26 washes the lower body of the user seated on the toilet seat 22. The deodorizing device 30 sucks and deodorizes odor generated in the toilet bowl 12.
The drying device 28 sucks in gas (air) by a fan (not shown), heats the sucked air by a heater (not shown), and blows out the heated air as dry air. The drying device 28 blows dry wind toward the lower body of the user to dry the lower body. As described later, the drying device 28 blows dry air to the back surface of the toilet seat after the toilet seat back surface is cleaned, and dries the back surface of the toilet seat.
The toilet seat opening and closing motor 40 is housed in the toilet seat 22. The toilet seat 22 is opened and closed as the rotary shaft 40a of the toilet seat opening and closing motor 40 rotates. Hereinafter, the state in which the toilet seat 22 is laid down on the bowl 12 of the toilet main body 14 is referred to as "closed state". In fig. 1, the toilet seat 22 is shown in a closed state.
The toilet cover 24 is rotatably attached to the casing 20 via a hinge mechanism, not shown, in the same manner as the toilet seat 22. The toilet lid 24 is driven by a toilet lid opening/closing motor, not shown, to be opened and closed.
Fig. 3 is a bottom view of the toilet seat unit 16 and the cabinet 20. The toilet device 10 further includes: a toilet seat back surface cleaning mechanism 42 for cleaning the back surface 22a of the toilet seat 22 with a cleaning liquid; and a sealing member 60 for suppressing leakage of the cleaning liquid.
The toilet seat back cleaning mechanism 42 includes: at least one (five in this example) discharge portion 46 capable of discharging the cleaning liquid to reach the back surface 22a of the toilet seat 22; a liquid supply path 48 for supplying the cleaning liquid to the discharge portion 46; and an opening/closing valve 50 provided in the middle of the liquid supply passage and capable of opening/closing the liquid supply passage 48. The opening/closing valve 50 is, for example, an electromagnetic valve, and is opened and closed in accordance with a control command from a control unit 70 (described later). The liquid supply path 48 is constituted by a hose or the like disposed inside the tank 20 and the toilet seat 22. The liquid supply path 48 includes a common path 48a and at least one branch path 48b that branches from the common path 48a and connects to each discharge portion 46.
In the present embodiment, the discharge portion 46 is formed integrally with the toilet seat 22 on the back surface 22a of the toilet seat 22. The discharge portion 46 has an inlet (not shown) connected to the branch path 48b, a discharge port 46a for discharging the cleaning liquid, and a communication hole (not shown) for communicating the inlet with the discharge port 46 a.
When the opening/closing valve 50 opens the liquid supply passage 48, the cleaning liquid is supplied from the liquid supply passage 48 to the discharge portion 46, and the cleaning liquid is discharged from the discharge port 46a of the discharge portion 46 to reach the back surface 22a of the toilet seat 22. Thereby, the back surface 22a of the toilet seat 22 is cleaned. When the opening/closing valve 50 closes the liquid supply passage, the supply of the cleaning liquid from the liquid supply passage 48 to the discharge portion 46 is stopped, and the discharge of the cleaning liquid from the discharge portion 46 is stopped.
Fig. 4 is an enlarged cross-sectional view showing a part of the toilet apparatus 10 in an enlarged manner. The sectional view of the toilet seat 22 of fig. 4 corresponds to the sectional view taken along line a-a of fig. 3. Reference is made to fig. 4 on the basis of fig. 3. The seal member 60 is an elastic body such as rubber. The sealing member 60 is fixed to the back surface 22a of the toilet seat 22 by an adhesive, for example. The sealing member 60 is provided on the opposite side of the discharge portion 46 from the central opening portion 32 with respect to the discharge portion 46, and is sandwiched between the toilet seat 22 and the bowl 12 when the toilet seat 22 is in the closed state, and suppresses the cleaning liquid from leaking out from between the toilet seat 22 and the bowl 12 when cleaning the back surface of the toilet seat. The sealing member 60 is preferably formed in a ring shape as shown in fig. 3, is fixed to the back surface 22a of the toilet seat 22 so as to surround the central opening 32 and all the discharge portions 46, and is sandwiched between the toilet seat 22 and the bowl 12 over the entire circumference when the toilet seat 22 is in the closed state.
For example, depending on manufacturing errors, the contact surface between the bowl 12 and the sealing member 60 of the toilet seat 22 may not be flat. In this case, if only the toilet seat 22 is closed, a gap is formed between the sealing member 60 and the toilet seat 22 and/or the bowl 12, and the cleaning liquid may leak through the gap. Then, at least in the toilet bowl back surface cleaning, the toilet bowl 22 is pressed (urged) against the toilet bowl 12 to increase the close contact between the sealing member 60 and the toilet bowl 22 and the toilet bowl 12, that is, to reduce the gap between the sealing member 60 and the toilet bowl 22 and the toilet bowl 12. In the present embodiment, as will be described later, the toilet seat opening/closing motor 40 is continuously rotated in the direction to close the toilet seat 22 during the toilet seat back surface washing. This can maintain the state in which the toilet seat 22 is pressed against the toilet bowl 12.
Here, the toilet seat 22 is generally formed of resin, and the bowl 12 is formed of pottery. Since the pottery has lower processing accuracy than the resin, the bowl 12 has a large manufacturing error. When the seal member 60 and the toilet seat 22 are fixed by an adhesive or the like, they may be fixed without a gap therebetween. In the present embodiment, the hardness of the sealing member 60 and the pressing force for pressing the toilet seat 22 against the toilet bowl 12 are determined so that the sealing member 60 is crushed by at least the tolerance (for example, 3mm to 7mm) of the toilet bowl 12 to improve the close contact between the sealing member 60 and the toilet bowl 12, that is, to reduce the gap between the sealing member 60 and the toilet bowl 12. They are determined experimentally.
As a modification, the sealing member 60 may be fixed to the upper surface 12a of the bowl 12. In this case, the sealing member 60 is preferably formed in a ring shape so as to surround all the discharge portions 46 when the toilet seat 22 is in the closed state, and is sandwiched between the toilet seat 22 and the bowl 12 over the entire circumference.
Fig. 5 is a block diagram showing a control system of the toilet system 1. The respective modules shown here are realized by elements or mechanical devices including a cpu (central Processing unit) of a computer in hardware, and by computer programs or the like in software, but functional modules realized by cooperation of these are depicted here. Therefore, it can be understood by those skilled in the art who have the present specification that these functional modules can be implemented in various forms by a combination of hardware and software.
The toilet apparatus 10 further includes a human body detection sensor 52, a contact detection sensor (seating detection sensor) 54, an open/close detection sensor 56, and a control unit 70.
The human body detection sensor 52 detects a human body (user) within a predetermined detection range in a non-contact manner. In the present embodiment, the human body detection sensor 52 is configured to detect a user in a toilet (toilet room). The human body detection sensor 52 is provided at a position where a human body can be detected regardless of the open/close state of the toilet seat 22 and the toilet cover 24. The human body detection sensor 52 transmits the detection result to the control unit 70.
The contact detection sensor 54 is, for example, an electrostatic sensor, and detects contact between the user and the toilet seat 22. Specifically, the contact detection sensor 54 detects contact (seating) when the user sits on the toilet seat 22 and the buttocks contact the toilet seat 22. The contact detection sensor 54 detects contact when the user is about to open the toilet seat 22 and the user's hand touches the toilet seat 22. The contact detection sensor 54 transmits the detection result to the control unit 70.
The open/close detection sensor 56 is, for example, an angle sensor, and detects opening/closing of the toilet seat 22. The open/close detection sensor 56 transmits the detection result to the control unit 70.
The control unit 70 includes a communication unit 72, an operation control unit 74, and a storage unit 76. The communication unit 72 receives the wireless signal transmitted from the remote control device 8 and specifies the operation content of the user with respect to the toilet apparatus 10.
The operation control unit 74 controls the start and stop of the toilet seat back surface cleaning by the toilet seat back surface cleaning mechanism 42. The operation controller 74 controls the drying of the toilet seat back surface by the drying device 28 after the toilet seat back surface is cleaned. The following description will be specifically made.
The control for starting the toilet seat back surface cleaning will be described. The operation controller 74 starts the toilet seat back surface cleaning when the toilet seat 22 is in the closed state and any of the following starting conditions a1 to a4, for example, is satisfied. Specifically, the operation controller 74 first keeps rotating the rotary shaft 40a of the toilet seat opening/closing motor 40 in the rotation direction in which the rotary shaft 40a is rotated when the toilet seat 22 is closed. This presses the toilet seat 22 against the toilet bowl 12, thereby improving the close contact between the sealing member 60 and the toilet seat 22 and toilet bowl 12. In this state, the operation controller 74 opens the on-off valve 50 to open the liquid supply passage 48. The user can select the starting conditions to be used for a2 to a4.
A1. The user performs the operation of starting the back washing of the toilet seat by the remote control device
A2. Reaching the scheduled start time of the toilet seat back surface cleaning
The plan for executing the toilet seat back surface cleaning is stored in the storage unit 76 in advance. The operation control unit 74 periodically refers to the storage unit 76, and starts the cleaning of the back surface of the toilet seat when the scheduled date and time is reached. The plan for washing the back of the toilet seat may be, for example, once a day at a predetermined time, once a week at a predetermined time, or at a predetermined time on a certain day of the week.
A3. After a predetermined time has elapsed since the last cleaning of the back surface of the toilet seat
The operation control unit 74 is executed when a predetermined time (for example, 1 hour, 3 hours, or 5 hours) has elapsed since the last toilet seat back surface cleaning, for example, with reference to the start time of the toilet seat back surface cleaning. In this case, the predetermined time is stored in the storage unit 76 in advance. The time (e.g., start time) at which the toilet seat back surface cleaning on the upper side is executed is also stored in the storage unit 76. The operation control unit 74 periodically refers to the storage unit 76, and starts the toilet seat back surface cleaning when a predetermined time has elapsed since the start of the toilet seat back surface cleaning in the previous time. When the toilet seat back surface cleaning is started, the operation control unit 74 updates the execution time (start time) of the storage unit 76 to the current time.
A4. When the number of uses of the toilet device 10 after the previous toilet seat back cleaning reaches a predetermined number
The operation control unit 74 counts the number of uses of the toilet apparatus 10 by regarding the number of times of toilet flushing as the number of uses of the toilet apparatus 10. In the toilet cleaning, the toilet bowl 12 is cleaned by supplying washing water to the toilet bowl 12 so that the waste discharged is discharged. The number of times the toilet apparatus 10 is used is stored in the storage unit 76. The operation control unit 74 increments the number of times the storage unit 76 is used by one every time toilet flushing is performed. When the number of uses reaches a predetermined number, the operation control unit 74 starts the toilet seat back surface cleaning and clears the number of uses of the storage unit 76. For example, when the predetermined number of times is 1, the toilet seat back washing is performed after each use of the toilet device 10, and when the predetermined number of times is 10, the toilet seat back washing is performed every 10 uses.
The operation controller 74 may skip the toilet seat back cleaning when any one of the start conditions a1 to a4 is satisfied and the toilet seat 22 is in the open state, but may control the toilet seat opening/closing motor 40 to cause the toilet seat 22 to be in the closed state and start the toilet seat back cleaning.
When the user performs the operation of starting the toilet seat back surface cleaning using the remote control device, the user is considered to be in the toilet room thereafter. In this case, when any of the start conditions a1 to a4 is satisfied but the toilet seat 22 is in the open state, the user may be notified of the closing of the toilet seat 22. The notification may be a notification by sound or a notification by the display unit 8b of the remote control device 8.
Next, the control for stopping the toilet seat back surface cleaning will be described. The operation controller 74 stops the toilet seat back surface cleaning when any of the following stop conditions B1 to B6 is satisfied. Specifically, the operation controller 74 first closes the liquid supply passage 48 with the on-off valve 50. Then, the operation control unit 74 stops the rotation of the rotary shaft 40a of the toilet seat opening/closing motor 40. Preferably, the operation control unit 74 stops the rotation of the rotary shaft 40a of the toilet seat opening/closing motor 40 after a predetermined time has elapsed since the opening/closing valve 50 was closed. The predetermined time is set to a time at which the cleaning liquid in the liquid supply passage 48 having passed through the on-off valve 50 flows out reliably. The user can select the stop conditions to be used for B4 to B6.
B1. Case where the back surface of the toilet seat is cleaned at a predetermined cleaning time
B2. The user can stop the cleaning operation of the back of the toilet seat via the remote control device
B3. When the user operates the toilet seat 22 to be opened by the remote control device
The operation control unit 74 controls the toilet seat opening/closing motor 40 to lift the toilet seat 22 after the toilet seat back surface cleaning is stopped. The operation controller 74 lifts the toilet seat 22 after a predetermined period of time elapses after the opening/closing valve 50 is closed and the discharge from the discharge portion 46 is appropriately stopped.
B4. In the case where a human body is detected by the human body detection sensor 52
When the user is in the toilet, the cleaning liquid cleaned on the back surface of the toilet seat may scatter around the user through the central opening 32 or the like. In addition, in the toilet seat back surface cleaning, the toilet bowl 12 is pushed by the toilet seat 22 by the toilet seat opening/closing motor 40, but the user can open the toilet seat 22 with a large force. In this case, the cleaning liquid for cleaning the back surface of the toilet seat may scatter around. Then, when the human body detection sensor 52 detects a human body, that is, when the user enters a toilet (toilet room), the operation control unit 74 stops the toilet seat back surface cleaning.
However, when the user operates the remote control device in the toilet to start the toilet seat back surface washing, the toilet seat back surface washing is not stopped even if the human body detection sensor 52 detects a human body. In addition, when the remote control device is operated to start the toilet seat back washing, since a user other than the user who starts the toilet seat back washing may enter the toilet after a predetermined time has elapsed from the start, the toilet seat back washing may be stopped when the human body detection sensor 52 detects a human body.
B5. When the contact detection sensor 54 detects that the user is in contact with the toilet seat 22
When a user sits on the toilet seat 22 during toilet seat back washing, the washing liquid for toilet seat back washing may scatter around the center opening 32 or the like, and may splash onto the seated user. As described above, even in the toilet seat back surface cleaning, the user can open the toilet seat 22 with a large force, and in this case, the cleaning liquid for the toilet seat back surface cleaning may be scattered around. Then, when the contact detection sensor 54 detects that the user is in contact with the toilet seat 22, the operation control unit 74 stops the toilet seat back surface cleaning.
B6. The open/close detection sensor 56 detects that the toilet seat 22 is in the non-closed state
As described above, in the toilet seat back surface cleaning, the user can lift the toilet seat 22 with a large force, and in this case, the cleaning liquid for toilet seat back surface cleaning may be scattered around. Then, when the open/close detection sensor 56 detects that the toilet seat 22 is in the non-closed state, the operation control unit 74 stops the toilet seat back surface cleaning.
Next, the drying control after the toilet seat back surface cleaning will be described.
When the toilet seat back surface cleaning by the toilet seat back surface cleaning mechanism 42 is stopped, the operation control unit 74 causes the drying device 28 to perform the toilet seat back surface drying if the toilet seat 22 is in the closed state. Specifically, the drying device 28 blows dry air to the back surface of the toilet seat 22. The larger stream of water droplets thus falls to the bowl 12. The cleaning liquid adhering to the back surface of the toilet seat 22 is concentrated downstream of the drying air by the wind pressure of the drying air. The collected cleaning liquid forms large water droplets, and the droplets are blown down into the toilet bowl 12 by the drying air. The drying device 28 blows (sends) warm air as dry air to the back surface of the toilet seat 22. This volatilizes the cleaning liquid adhering to the back surface of the toilet seat 22. The wind speed, temperature, and blowing time of the drying air can be determined by experiments.
Next, the effects of the present embodiment will be described. According to the present embodiment, since the toilet seat back surface cleaning is not performed when the toilet seat 22 is in the non-closed state, the cleaning liquid discharged from the discharge portion 46 during the toilet seat back surface cleaning can be suppressed from scattering around the toilet device 10.
Further, according to the present embodiment, when the human body detection sensor 52 detects a user during toilet seat back washing, that is, when entry into a toilet (toilet room) is detected, the toilet seat back washing is stopped. This can prevent the cleaning liquid for cleaning the back surface of the toilet seat from splashing on the user. Further, it is possible to avoid the situation where the user lifts the toilet seat 22 and the cleaning liquid is scattered around the toilet apparatus 10 during the toilet seat back surface cleaning.
Further, according to the present embodiment, when the contact detection sensor (seating detection sensor) 54 detects that the user is in contact with the toilet seat 22 during toilet seat back washing, the toilet seat back washing is stopped. For example, when the user sits on the toilet seat 22, the toilet seat back surface cleaning is stopped. This can prevent the washing liquid for washing the back surface of the toilet seat from being splashed on the user seated on the toilet seat 22 and causing discomfort to the user. Further, for example, when the user wants to lift the toilet seat 22 and contacts the toilet seat 22, the toilet seat back surface cleaning is stopped. This can prevent the user from lifting the toilet seat 22 and scattering the cleaning liquid around the toilet apparatus 10 during the toilet seat back surface cleaning.
Further, according to the present embodiment, when the toilet seat back surface cleaning open/close detection sensor 56 detects that the toilet seat 22 is in the non-closed state, the toilet seat back surface cleaning is stopped. Thus, since the toilet seat back surface cleaning is stopped when the user lifts the toilet seat 22, the cleaning liquid can be prevented from scattering around the toilet device 10.
Further, according to the present embodiment, in the toilet seat back surface cleaning, the toilet seat 22 is pressed against the toilet bowl 12, in other words, the toilet seat 22 is biased in the closing direction. This makes it difficult to lift the toilet seat 22, and prevents the cleaning liquid from being scattered around the toilet apparatus 10 when the user lifts the toilet seat 22 during the toilet seat back surface cleaning. Further, the sealing member 60 is improved in close contact with the toilet seat 22 and the toilet bowl 12, and the cleaning liquid for cleaning the back surface of the toilet seat can be prevented from leaking between the toilet seat 22 and the toilet bowl 12.
Further, according to the present embodiment, the toilet seat 22 is biased in the closing direction by the toilet seat opening/closing motor 40. That is, the toilet seat 22 can be biased in the closing direction without separately providing a dedicated mechanism for biasing the toilet seat 22 in the closing direction.
Further, according to the present embodiment, the sealing member 60 is preferably formed in a ring shape and is sandwiched between the toilet seat 22 and the toilet bowl 12 over the entire circumference. This can more reliably prevent the cleaning liquid for cleaning the back surface of the toilet seat from leaking between the toilet seat 22 and the toilet bowl 12.
Further, according to the present embodiment, after the toilet seat back surface is cleaned, the back surface of the toilet seat 22 is dried by the drying device 28. This can suppress the generation of mold and bacteria due to the cleaning liquid (moisture) adhering to the back surface of the toilet seat 22, and can keep the toilet apparatus 10 clean.
Further, according to the present embodiment, in the drying of the back surface of the toilet seat 22, the drying air is blown to the back surface of the toilet seat 22. This causes a large droplet of the cleaning liquid attached to the back surface of the toilet seat 22 to drop into the toilet bowl 12. The cleaning liquid adhering to the back surface of the toilet seat 22 is collected downstream of the drying air by the wind pressure of the drying air. The collected cleaning liquid forms large water droplets, and the droplets are blown down into the toilet bowl 12 by the drying air. As a result, the back surface of the toilet seat 22 is dried.
Further, according to the present embodiment, in the drying of the back surface of the toilet seat 22, warm air is blown as dry air to the back surface of the toilet seat 22. This volatilizes the cleaning liquid adhering to the back surface of the toilet seat 22, and as a result, the back surface of the toilet seat 22 is dried.
The toilet device 10 of the embodiment is explained above. The embodiment is merely an example, and it is possible for those skilled in the art to implement various modifications to the combination of the respective constituent elements, and such modifications are also included in the scope of the present invention.
(modification 1)
Fig. 6 is a side view showing a toilet apparatus 10 according to the embodiment in a modification. In the present modification, the lock mechanism suppresses the toilet seat 22 from being lifted during toilet seat back surface cleaning, and the lock mechanism presses the toilet seat 22 against the toilet bowl 12, thereby increasing the close contact between the sealing member 60 and the toilet seat 22 and the toilet bowl 12. Hereinafter, the toilet device 10 will be described mainly focusing on differences from the toilet device 10 of the embodiment.
The toilet device 10 includes a toilet main body 14, a toilet unit 16, a tank (not shown), a toilet back surface cleaning mechanism (not shown), a sealing member (not shown), and a lock mechanism 80.
The lock mechanism 80 is provided behind the toilet seat unit 16. The locking mechanism 80 includes a locking pin 82 and a drive device 84. The lock pin 82 is a rod-shaped member extending in the front-rear direction, and is fixed to the toilet main body 14 via a drive device 84. The driving device 84 moves the lock pin 82 forward and backward under the control of the operation control unit 74 of the control unit 70. A hole 22b into which the lock pin 82 can enter is formed in the toilet seat 22. When the lock pin 82 enters the hole 22b of the toilet seat 22, the toilet seat 22 is locked in the closed state. When the lock pin 82 retreats from the hole 22b of the toilet seat 22, the lock of the toilet seat 22 is released. Fig. 6 shows a state in which the lock pin 82 enters the hole 22b of the toilet seat 22 and the toilet seat 22 is locked in the closed state.
The operation controller 74 starts the toilet seat back surface cleaning when any of the starting conditions a1 to a4 is satisfied while the toilet seat 22 is in the closed state, as in the embodiment. Specifically, the operation controller 74 first keeps rotating the rotary shaft 40a in the rotation direction in which the rotary shaft 40a of the toilet seat opening/closing motor 40 rotates when the toilet seat 22 is closed. Thereby, the toilet seat 22 is pressed against the toilet bowl 12, and the close contact between the sealing member 60 and the toilet seat 22 and the toilet bowl 12 is improved. In this state, the operation controller 74 controls the driving device 84 of the lock mechanism 80 to cause the lock pin 82 to enter the hole 22b, thereby locking the toilet seat 22 in the closed state. The operation controller 74 stops the rotation of the rotary shaft 40a of the toilet seat opening/closing motor 40. Since the toilet seat 22 can maintain the state where the toilet bowl 12 is pressed by the lock mechanism 80, the close contact between the sealing member 60 and the toilet seat 22 and the toilet bowl 12 can be maintained at a high level even when the rotation of the rotary shaft 40a of the toilet seat opening and closing motor 40 is stopped. Then, the operation controller 74 opens the liquid supply passage 48 with the on-off valve 50.
Similarly to the embodiment, the operation controller 74 stops the toilet seat back surface cleaning when any of the stop conditions B1 to B6 is satisfied. Specifically, the operation controller 74 closes the liquid supply passage 48 with the on-off valve 50. Then, the operation control unit 74 releases the lock of the toilet seat 22 by retracting the lock pin 82 from the hole 22 b.
The toilet device 10 can provide the same operation and effect as those of the toilet device 10 of the embodiment. Further, according to the toilet apparatus 10, the toilet seat 22 cannot be lifted during the toilet back washing, and therefore, it is possible to prevent the cleaning liquid from scattering when the user lifts the toilet seat 22 during the toilet back washing.
(modification 2)
In the embodiment, the description has been given of the case where the rotating shaft 40a of the toilet seat opening and closing motor 40 is continuously rotated to urge the toilet seat 22 in the closing direction during the toilet seat back washing, but if the toilet seat 22 is only prevented from being lifted, the toilet seat 22 may be urged in the closing direction only when the human body is detected by the human body detection sensor 52 during the toilet seat back washing, that is, when the user enters the toilet during the toilet seat back washing. When the human body detection sensor 52 does not detect a human body, the rotating shaft 40a of the toilet seat opening/closing motor 40 may be continuously rotated at a low rotation speed, and when the human body detection sensor 52 detects a human body, the rotating shaft 40a of the toilet seat opening/closing motor 40 may be rotated at a high rotation speed.
In the above-described modification, the case where the lock mechanism 80 locks the toilet seat 22 so as not to be lifted during the toilet seat back washing has been described, but if the toilet seat 22 is only prevented from being lifted, the lock mechanism may lock the toilet seat 22 so as not to be lifted only when the human body is detected by the human body detection sensor 52 during the toilet seat back washing, that is, when the user enters the toilet during the toilet seat back washing.
(modification 3)
In the embodiment and the above-described modification, the operation control unit 74 does not pay attention to the open/close state of the toilet lid 24 during the toilet seat back washing, but the open/close state of the toilet lid 24 may be included in the start condition and the stop condition of the toilet seat back washing. Specifically, the operation controller 74 may start the toilet seat back surface cleaning when the toilet seat 22 is in the closed state and the toilet cover 24 is in the non-closed state. That is, the operation controller 74 may start the toilet seat back surface cleaning when the toilet seat 22 and the toilet lid 24 are both closed and any of the above-described start conditions a1 to a4 are satisfied. The operation controller 74 may stop the toilet seat back washing even when the toilet seat 22 is in the closed state when the toilet cover 24 is in the non-closed state during the toilet seat back washing. In these cases, the cleaning liquid for cleaning the back surface of the toilet seat is caught by the toilet lid 24 even if it flies out from the central opening 32 of the toilet seat 22. That is, the cleaning liquid for toilet bowl back washing can be suppressed from scattering to the outside of the toilet bowl apparatus 10, and the toilet can be kept clean.
(modification 4)
Although not particularly mentioned in the embodiment and the above modifications, various modifications can be considered in the structure of the seal member 60. Fig. 7 (a) and (b) are cross-sectional views showing a modified example of the seal member 60 and its periphery, respectively. Fig. 7 (a) and (b) show a state before the toilet seat 22 is pressed against the toilet bowl 12.
In fig. 7 (a), the sealing member 60 is formed so that the bowl 12 side (the side not fixed) becomes thinner as it goes away from the toilet seat 22. In this case, the toilet bowl 12 side of the sealing member 60 is easily deformed, and the close contact between the toilet seat 22 and the toilet bowl 12 when the sealing member 60 is sandwiched therebetween is improved.
In fig. 7 (b), the sealing member 60 is made of rubber, and the first portion 60a having a high hardness (for example, a hardness of 60 degrees or more) on the toilet seat 22 side (the side not fixed) and the second portion 60b having a low hardness (for example, a hardness of 30 or less) on the toilet bowl 12 side are integrated by two-color molding. In this case, the first portion 60a having high hardness receives the weight of the toilet seat 22 and the user so that the toilet seat 22 does not come into direct contact with the bowl 12. The second portion 60b having low hardness is largely deformed to fit the bowl 12.
(modification 5)
Fig. 8 is a sectional view of a toilet apparatus according to a modification. Fig. 8 corresponds to fig. 4. An inner portion 22a2 of the back surface 22a of the toilet seat 22, which is located inside the outer portion 22a1 facing the upper surface 12a of the toilet bowl 12, is an inclined surface inclined with respect to the horizontal plane. In the example of fig. 8, the sectional shape of the inside portion 22a2 has an inverted U-shape. According to the present modification, when the drying air is blown, the cleaning liquid attached to the inner portion 22a2 flows on the inclined surface and falls to the bowl 12. That is, the cleaning liquid easily flows down.
(modification 6)
Fig. 9 is a sectional view of a toilet apparatus according to a modification. Fig. 9 corresponds to fig. 4. In the present modification, the bowl 12 has an outer upper surface 12a1 and an inner upper surface 12a2 located inside and below the outer upper surface 12a 1. The outer upper surface 12a1 and the inner upper surface 12a2 are connected by a connecting wall 12 b. The sealing member 60 is sandwiched between the back surface 22a of the toilet seat 22 and the inside upper surface 12a2 when the toilet seat 22 is in the closed position. In this case, even if the cleaning liquid leaks to the outside of the sealing member 60, the cleaning liquid can be received by the connecting wall 12 b. That is, according to the present modification, the leakage of the cleaning liquid can be more reliably suppressed.
(modification 7)
Although not particularly mentioned in the embodiment, the toilet seat back washing mechanism 42 may have a plurality of washing modes different in washing mode in the toilet seat back washing. For example, the toilet seat back washing performed by the toilet seat back washing mechanism 42 may have a plurality of washing modes different in at least one of the following items.
Cleaning time (i.e. time for discharging cleaning liquid)
Sum of discharge flow rates discharged from all the discharge ports 46a
Temperature of the cleaning liquid
The type of cleaning liquid (e.g., water containing cleaning agent, etc.)
For example, the toilet seat back surface cleaning by the toilet seat back surface cleaning mechanism 42 may include a first cleaning mode, a second cleaning mode in which the cleaning time is longer than that in the first cleaning mode and the discharge flow rate is large, and a third cleaning mode in which the cleaning time is longer than that in the second cleaning mode and the temperature of the cleaning liquid is high.
The total of the discharge flow rates may be adjusted by increasing or decreasing the discharge flow rate from each discharge port 46a, or may be adjusted by increasing or decreasing the number of discharge ports 46a to be discharged.
The plurality of washing modes may be distinguished by any one of the following or a combination thereof, for example.
Predetermined plan
The number of uses of the toilet apparatus 10 after the previous toilet seat back cleaning
Whether the user urinates or defecates
Operation of the remote control device 8
For example, the operation control unit 74 may execute the toilet seat back washing in the first washing mode each time the toilet apparatus 10 is used, execute the toilet seat back washing in the second washing mode at a predetermined timing once a day, and execute the toilet seat back washing in the third washing mode at a predetermined timing once a week.
For example, the operation control unit 74 may execute the toilet seat back washing in the first washing mode when the number of uses of the toilet device 10 after the previous toilet seat back washing reaches 10 times, and may execute the second washing mode when the number of uses reaches 30 times.
For example, the operation control unit 74 performs the toilet seat back surface cleaning in the first cleaning mode after the toilet is urinated, and performs the second cleaning mode after the toilet is defecated. The operation controller 74 may determine whether the user urinates or defecates based on, for example, the time when the user is seated on the toilet seat 22, that is, the time detected by the contact detection sensor 54.
Further, the remote control device 8 can select the cleaning mode to be executed, and the operation control unit 74 can execute the toilet seat back cleaning in the selected cleaning mode when the remote control device starts the toilet seat back cleaning operation.
(modification 8)
In the embodiment, the description has been given of the case where the seat back surface cleaning is not performed in the non-closed state of the seat 22 by the control (i.e., electrical control) performed by the control unit 70, but the cleaning may be mechanically performed. Specifically, for example, the on-off valve 50 is a mechanical valve, and when the toilet seat 22 is in the non-closed state, the on-off valve 50 is mechanically closed in conjunction therewith.
(modification 9)
In the embodiment, the description has been given of the case where the contact detection sensor 54 functions as a seating detection sensor, but the present invention is not limited to this, and the toilet apparatus 10 may be provided with a seating detection sensor instead of the contact detection sensor 54 or separately from the contact detection sensor 54. The seating detection sensor may detect seating by a distance from the user, or may include a switch provided on the back surface of the toilet seat 22, and the switch may be pressed when the user sits on the toilet seat 22 to detect seating.
(modification 10)
In the embodiment and the above modification, the case where the toilet seat 22 is pressed against the toilet bowl 12 to increase the close contact between the sealing member 60 and the toilet seat 22 and the toilet bowl 12 in the toilet seat back surface cleaning has been described, but the present invention is not limited to this, and the toilet seat 22 may be pressed against the toilet bowl 12 in the toilet seat cleaning, for example. Specifically, for example, when the user performs the operation of starting toilet flushing using the remote control device 8, the operation control unit 74 may continue to rotate the toilet opening/closing motor 40 in the direction for closing the toilet seat 22 for a predetermined time (until toilet flushing is surely completed). Thereby, the toilet seat 22 is pressed against the toilet bowl 12.
(modification 11)
Although not particularly mentioned in the embodiment and the above modification, the toilet seat back drying may be performed in a state where the toilet seat 22 is pressed against the toilet bowl 12 to increase the close contact between the sealing member 60 and the toilet seat 22 and the toilet bowl 12. Specifically, for example, when the toilet seat back washing by the toilet seat back washing mechanism 42 is stopped, the operation control unit 74 rotates the toilet seat opening/closing motor 40 continuously in a direction to close the toilet seat 22 for a predetermined time. Thereby, the toilet seat 22 is pressed against the toilet bowl 12. Further, the toilet seat 22 can be kept pressed against the toilet bowl 12 from the start of the toilet seat back surface washing to the end of the toilet seat back surface drying. The operation controller 74 causes the drying device 28 to dry the back surface of the toilet seat while pressing the toilet seat 22 against the toilet bowl 12. According to this modification, the cleaning liquid blown off by the drying air from the drying device 28 can be prevented from leaking between the toilet seat and the toilet main body.
(modification 12)
In the embodiment, the case where the toilet seat back drying is performed after the toilet seat back washing is described, but the present invention is not limited thereto. For example, the toilet seat back drying may be performed after the toilet seat is washed. For example, the operation control unit 74 may start drying the back surface of the toilet seat after a predetermined time (time for reliably finishing toilet cleaning) has elapsed from the start of toilet cleaning.
(modification 13)
As a further modification, the toilet seat unit 16 may include the toilet seat back surface cleaning mechanism 42 and a function of controlling the toilet seat back surface cleaning mechanism 42 in the control unit 70. That is, the toilet seat unit 16 may be configured to be able to perform toilet seat back surface cleaning.
