Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device provided with a deodorizing device, and more particularly to a technology for efficiently deodorizing, saving energy and extending the life of a deodorant.

[0002]

2. Description of the Related Art In order to treat odors inevitably generated during defecation, a deodorizing device is often attached to a hot water flush toilet seat device. One example is the registered utility model 25970
No. 19 discloses this. Thus, in the hot water flush toilet seat device disclosed in this publication, even if the seating sensor sends a signal to the effect that the user has left the toilet seat to the control device,
The control device continues to operate the deodorizing device until a predetermined time has elapsed, thereby effectively performing the odor treatment. Further, the seating sensor is of a type that determines that the user is seated on the toilet seat when receiving a force from the toilet seat side and issues a signal, that is, the seating sensor closes the switch when receiving a force from the toilet seat side. This is a type in which an ON signal (seating signal) is sent to the control device.

[0003]

However, the reason that the seat sensor receives the force from the toilet seat side is not limited to when the user sits on the toilet seat. When the seating sensor is located above and below the site, pressure is applied to the seating sensor. In particular, when cleaning the inside of the toilet with the right hand while holding down the relevant portion on the toilet seat with the left hand, the seating sensor immediately outputs an ON signal (seating signal), and in response to this signal, the control device activates the deodorizing device. . Then, even after the hand is released from the toilet seat, the deodorizing device continues to operate for a predetermined time. The operation of the deodorizing device is a waste of energy because the motor rotates the fan. In addition, since the deodorant is excessively deodorized even when deodorization is not required, the deodorant is wasted at this time, and the effective life of the deodorant is shortened.
Such a defect can be caused even when an infrared sensor is used.

[0004] Therefore, an object of the present invention is to provide a toilet seat device in which such a defect is eliminated.

[0005]

Means for Solving the Problems According to the first aspect of the present invention, which has been made to solve the above technical problem, it is recognized that a deodorizing device for performing odor treatment and a user sitting on a toilet seat are present. A seating sensor that emits a seating signal and a non-seating signal when and when it is not recognized, and a control device to which a seating signal or a non-seating signal from the seating sensor is input, and the control device, from the seating sensor An operation start process for starting the operation of the deodorizing device when a seating signal is received, and immediately stopping the operation of the deodorizing device when a non-seating signal is received from the seating sensor within a reference time after the operation starting process. Immediate stop processing and delay stop processing of stopping the deodorizing device after continuing the operation for a predetermined time when receiving a non-seating signal from the seating sensor after a reference time after the operation start processing. It is to toilet seat apparatus which is characterized in that the run.

In order to solve the above-mentioned technical problem, the invention of claim 2 provides a deodorizing device for performing odor treatment,
A seating sensor for transmitting information according to the presence or absence of an object on the toilet seat, and a control device to which information transmitted from the seating sensor is input, wherein the control device transmits the information input from the seating sensor to the toilet seat. The seating detection processing to determine whether the seating detection information indicates that there is an object on the top or the non-seat detection information indicating that there is no object on the toilet seat, and the information input from the seating sensor in the seating determination processing is An operation start process for starting the operation of the deodorizing device when it is determined that the detection information is the seating detection information, a measurement process for measuring the duration of the seating detection information input from the seating sensor, and the duration being within a reference time And the operation of the deodorizing device is immediately stopped when it is determined in the duration comparison processing that the duration is within the reference time. Time stop processing, and a delay stop processing for stopping the operation of the deodorizing device after a predetermined time has elapsed after the duration comparison processing when it is determined that the duration exceeds the reference time in the duration comparison processing. And a toilet seat device.

[0007] According to a third aspect of the present invention, in the first or second aspect, the seating sensor is an infrared sensor.

According to the first and second aspects of the present invention, when the user is not seated on the toilet seat, the seating sensor recognizes that the user is seated on the toilet seat and issues a seating signal according to, for example, the behavior of the person to be cleaned. Even so, in such a case, the time during which the seating signal is continuously emitted is short. Therefore, if the duration of the continuous generation of the seating signal is shorter than the reference time, it is determined that the seat is not seated on the toilet seat, and if the operation of the deodorizing device is stopped immediately when the seating signal is cut off, energy is wasted. Energy consumption, reducing energy consumption, reducing the chance of using a deodorant when deodorization is unnecessary, extending the life of the deodorant, and extending the life of the deodorant. Can be.

In particular, as described in the third aspect of the present invention, when the seating sensor is an infrared sensor, it is highly probable that the user will recognize that the user is seated on the toilet seat, so that the above-mentioned effects can be obtained. The benefits of doing so are great.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3, the hot water flush toilet seat device includes a main body 12 mounted on a rear portion of an upper surface of a toilet bowl 10. A toilet seat 14 placed on the toilet 10 and a toilet lid 16 placed on the toilet seat 14 are pivotally attached to the main body 12.
An infrared sensor 18 as a seating sensor is fitted in the center of the main body 12. This infrared sensor 18
Is for detecting the presence or absence of an object on the toilet seat 14 and transmitting information according to the presence or absence. When a person is within the detection range of the infrared sensor 18 (that is, on the toilet seat 14), the seating detection information is used. A certain ON signal (seating signal) is issued, otherwise, an OFF signal (non-seating signal) as non-seating detection information is issued (or the transmission of the ON signal is stopped).

A part 1 projecting forward from the left side of the main body 12
A control panel 20 is formed on the control panel 21. When the infrared sensor 18 emits an ON signal (seating signal), the control unit 22 is operated by operating a knob formed on the control panel 20. In response to the command signal, the cleaning mechanism 24 is operated as is well known, and one of the nozzles 26 and 28 is extended to perform the well-known cleaning.

At the same time as the infrared sensor 18 emits an ON signal (seating signal), the control device 22
Activate 0 to perform the well-known odor treatment. Deodorizing device 30
Is mounted in a portion 122 protruding forward from the right side of the main body 12. As is well known (for example, described in Japanese Patent Application Laid-Open No. 7-90908), the configuration of the deodorizing device 30 reduces the odor by rotating the fan 34 by the motor 32 and sucking the odor into the activated carbon (not shown). Is what you do.

Thus, the control device 22 includes the deodorizing device 30
Is controlled in the following manner. The specific contents will be described below with reference to the flowchart shown in FIG.

First, in step S10, it is determined whether the information input from the infrared sensor 18 is an ON signal (seating detection information) or an OFF signal (non-seating detection information) (seating determination processing). If it is determined that the signal is an off signal, that is, if No is determined in step S10, step S10 is repeated again. If it is determined that the signal is an ON signal, that is, if it is determined Yes in step S10, the process proceeds to step S20.

In step S20, a command signal for starting operation is output to the deodorizing device 30 in response to the input of the ON signal (operation start processing). As a result, the deodorizing device 30 operates to start deodorizing. At the same time, the timer T1 starts counting and measures the ON signal input duration (measurement processing). Thereafter, the process proceeds to step S30.

In step S30, it is determined whether the information input from the infrared sensor 18 when the deodorizing device 30 is operating is an ON signal (seating detection information) or an OFF signal (non-seating detection information). You. If it is determined that the signal is an ON signal, that is, if it is determined Yes in step S30, step S30 is repeated. If it is determined that the signal is an off signal, that is, if it is determined No in step S30, the process proceeds to step S40. This step S30 is a process of determining whether or not the ON signal is continued (ON signal continuation determination process). When the process proceeds from step S30 to step S40, continuous input of the ON signal (seating detection information) is performed. Indicates that has been cut off.

In step S40, the continuation time t1 of the timer T1 whose counting has been started in step S20 is compared with the reference time t0, and it is determined whether or not the continuation time t1 is within the reference time t0 (continuation time comparison). processing). This duration t1 is the time when the ON signal is continuously transmitted,
That is, it is the time during which an object on the toilet seat is detected by the infrared sensor 18, for example, when the user is actually sitting on the toilet seat and adding an object. This duration t
If it is determined that 1 is within the reference time t0, the process proceeds to step S70. On the other hand, the duration t1 is equal to the reference time t.
If it is determined that it exceeds 0, step S50
Proceed to. In this case, a time in the range of 2 to 60 seconds can be selected as the reference time t0.

If it is determined in step S40 that the duration t1 is within the reference time t0 and the process proceeds to step S70,
This is not a situation in which the duration t1 of the ON signal is short and the user is actually sitting on the toilet seat and using it, but is a false detection that the human body of the cleaner is detected by the infrared sensor 18 due to cleaning or the like. Is determined to be high.
In this case, since the toilet is not actually used in many cases, there is no need to operate the deodorizing device 30.
Therefore, in step S70, a command signal for stopping the operation of the deodorizing device 30 is output, and the operation of the deodorizing device 30 is immediately stopped. Steps S40 to S70
Is the immediate stop process.

If it is determined in step S40 that the continuation time exceeds the reference time and the process proceeds to step S50, the timer T2 starts counting in step S50. Thereafter, the process proceeds to step S60.

In step S60, the value t of the timer T2
It is determined whether or not 2 is equal to or less than a predetermined time t3. Timer T
When it is determined that the value t2 of 2 is equal to or shorter than the predetermined time t3, the step S60 is executed again. If it is determined that the value of the timer T2 has exceeded the predetermined time t3,
Proceed to step S70.

In step S70, as described above, a command signal for stopping the operation of the deodorizing device 30 is output, and the operation of the deodorizing device 30 is stopped.

If it is determined in step S40 that the duration t1 exceeds the reference time t0, it is highly probable that the user is actually sitting on the toilet seat and using the toilet, and this is not an erroneous detection. . For this reason, even after use, it is necessary for the user to continuously operate the deodorizing device to complete the deodorizing. Therefore, the predetermined time elapses in steps S50 and S60, and after the elapse of the predetermined time, the operation of the deodorizing device 30 is stopped in step S70. The processing from step S40 to steps S50, S60, and S70 is the delay stop processing. The predetermined time t3 is 10
~ 50 is preferably selected.

In this manner, the time during which the seating detection information is continuously transmitted is measured by the infrared sensor 18 (seating detection sensor). If the time is short (within the reference time), the seating detection information is cut off. Immediately (when the off signal is input), the operation of the deodorizing device 30 is immediately stopped, and when the time is long (exceeding the reference time), the seating detection information is cut off (when the off signal is input). By stopping the operation of the deodorizing device 30 after a predetermined time elapses, it is possible to minimize the operation of the deodorizing device 30 when deodorization is unnecessary, thereby contributing to energy saving and realizing a longer life of the deodorant. Can be.

[0025]

As described above, in the present invention,
When the user actually uses the toilet, the deodorizing device is operated for a predetermined time after the seat sensor is turned off, and when the user does not use the toilet, the seat sensor is turned off. The operation of the deodorizing device can be stopped to a necessary minimum, thereby contributing to energy saving. Further, waste of the deodorant can be prevented, and the life of the deodorant can be extended.
