Description of the Related Art A dummy sound generator is well known as a means for eliminating the need for washing to eliminate the sound of excretion when a woman uses a toilet and improving the water saving effect. Conventionally, a toilet cleaning device to which the onomatopoeic sound generation function has been added includes a toilet sound which is automatically detected when a user enters a toilet or seated on a toilet, and automatically generated when no user is detected. Toilet flushing device for supplying flush water to the toilet (Japanese Patent Laid-Open No. Hei 5-230852), an automatic switch to generate a dummy sound upon detecting a user entering a toilet or sitting on a toilet bowl, and an operation switch for generating a dummy sound Washing device for toilet, which is provided with a separate operation switch for washing and toilet and is also capable of independent manual operation
221806) has been proposed.

[0003]

However, in the toilet cleaning device proposed in Japanese Patent Application Laid-Open No. Hei 5-230852, unnecessary noises are generated when entering a toilet for the purpose of grooming and cleaning. However, there is a problem that the timing of the automatically generated onomatopoeia and the small excretion irrespective of the user's intention is shifted, so that the muffling effect cannot be obtained and the user may feel uncomfortable. there were.

Further, in the toilet cleaning device proposed in Japanese Patent Application Laid-Open No. 9-221806, washing with running water is performed by a cleaning operation switch despite the automatic generation of a sound by a dummy sound generating device. Is possible,
If a user who is not accustomed to such a device repeatedly performs running water washing for erroneous operation or mischief, there is a problem that an expected water saving effect cannot be obtained.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned disadvantages, and ensures that the user manually generates a dummy sound during a time period when the user wants to eliminate the excretion sound. The purpose of the present invention is to prevent the water from being displaced, to make it possible to wash with running water at the time of washing, and to prevent unnecessary washing with running water due to erroneous operation or mischief, thereby achieving a reliable water saving effect.

[0006]

According to the present invention, there is provided a toilet cleaning apparatus provided with an onomatopoeic sound generating means, in which the human body detecting means is in a detecting state or the human body detecting means is in a detecting state. And an operation switch from a toilet user during a predetermined period of time after the detection state is reached, or until the first operation instruction is issued after the human body detection means enters the detection state. Is activated in response to an operation instruction by the user.

As described above, when the human body detection means is in the detection state, when the human body detection means is in the detection state and for a predetermined period of time after the detection state, or when the human body detection means is in the detection state. Until the first operation instruction is issued after that, i.e., during a time period in which the toilet user wants to turn off the excretion sound after the toilet user has taken a toilet posture, the manual operation by the user's will is performed. As a result, it is possible to reliably generate the onomatopoeia, so that the timing between the onset of the onomatopoeia and the excretion for small items does not shift. Can be prevented and a certain water saving effect can be achieved.

Further, if a plurality of time charts of the selected operation are stored and the setting of the operation contents actually operated can be changed, the characteristics of the toilet user of the building in which the toilet cleaning device is installed can be improved. According to the owner's request, the operation content of the toilet cleaning device can be adjusted while checking the water saving effect in each time chart.

In addition, in response to an operation instruction from the operation switch, there is provided notification means for notifying the toilet user of which of the onset sound generating device and the water supply means is to be operated, at the time of operation. Thus, the toilet user can be provided with a sense of security, can be prevented from being misunderstood in operation, and can have a more reliable water saving effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. FIG. 1 is an external view showing an example of a toilet cleaning device according to the present invention. The toilet cleaning apparatus shown in FIG. 1 is provided with an infrared human body detection sensor 1 for detecting a human body of a toilet user, and an infrared hand sensor 2 for inputting an operation instruction of the user.

FIG. 2 shows the internal structure of the toilet cleaning apparatus shown in FIG. 1 without the upper outer cover 3. Inside, an electrically operated flash valve 4 for supplying flush water to the toilet, a dummy sound generating device 5 for generating a dummy sound such as running water noise, a detection result of the human body detection sensor 1 and a signal from the hand sensor 2 are used. A controller 6 for controlling the electrically operated flash valve 4 and the onomatopoeic generator 5 and a power supply unit 7 are built in. The human body detection sensor 1, the hand sensor 2, and the onomatopoeic generator 5 are integrated with the controller 6. It has a structure.

FIGS. 3 and 4 are views of the toilet cleaning apparatus shown in FIG. 1 as viewed from above. FIG. 3 shows the hand sensor 2 when running water cleaning is performed in response to an operation instruction from a user. As shown in FIG. 4, when “water” or an onomatopoeic sound is generated, the character “sound” is displayed by the light emitting element as shown in FIG. 4. The electrically operated flash valve 4 has a water supply port 8 for the flush valve, a drain port 9 from the flush valve to the toilet, and an emergency manual in case of failure of electrical operation due to a failure of an electric part. A cleaning button 10 is provided.

FIG. 5 is a perspective view of a toilet room in which the toilet cleaning device of FIG. 1 is installed in a Japanese-style toilet. As shown in FIG. 5, the human body detection sensor 1 has a human body detection area 11, and the hand sensor 2 has a hand detection area 12.

First, the basic operation of the toilet cleaning apparatus will be described with reference to a time chart shown in FIG. When the user who enters the toilet takes the toilet posture, the human body detection sensor 1 detects the human body, and the timer starts counting the usage time. Standing up after stool, human body detection sensor 1
At the time when is in the non-detection state, if the use time timer is within the predetermined magnitude determination time T1, it is determined that the user's convenience is small, and the user is automatically washed with the small amount of washing water.
In the case of one or more, the controller 6 is set to determine that the user's stool is stool and to perform automatic washing with a large amount of washing water.

[0015] In the automatic cleaning, a delay time T2 from the time when the human body detection sensor becomes non-detection state.
It is set to be done later. This is for the purpose of preventing automatic cleaning due to short-time detection failure due to movement of the human body during use.

When the user holds his hand over the hand sensor 2, the controller 6 generates a dummy sound to the dummy sound generator 5 or a signal for flushing the electrically operated flash valve 4 according to a set time chart. Send. In the same manner as described above, it is set so that flushing with running water can be performed based on the magnitude determination time T1 also by an operation instruction from the hand sensor 2 within the delay time T2.

Next, the operation described in claim 1 will be described with reference to a time chart shown in FIG. When the user enters the toilet and the human body detection sensor 1 is not sensing, the hand sensor 2 indicates that "water" is flowing. When the hand is held over the hand sensor 2 in this state, washing with running water is performed. This enables the user to perform cleaning before taking the toilet posture, and it is possible to instruct if the waste remains in the toilet or to perform cleaning for cleaning.

When the user takes a toilet posture and the human body detection sensor 1 is in the detection state, a display is made on the hand sensor 2 to indicate that "sound" flows, and the hand sensor is used to mute the excretion sound. In the case where the user wants to detect the sound 2 and perform cleaning, a dummy sound is generated from the dummy sound generation device 5 for a certain period of time, so that the user can use it without worrying about the excretion sound. In this time chart, when the human body detection sensor 1 is in the detection state, a dummy sound is always generated when the hand is held over the hand sensor 2, so that the water saving effect is high.

FIG. 8 is a time chart showing the operation according to the second aspect. The difference from the operation according to the time chart of FIG. 7 is that when the human body detection sensor 1 is in the detection state, if the human body detection time is shorter than the magnitude determination time T1, the artificial sound is generated in response to the instruction from the hand sensor 2, When the detection time is equal to or greater than the magnitude determination time T1, a dummy sound is generated in response to the instruction from the hand sensor 2 during T1 after the detection state is reached, and after the elapse of T1, the on-chip sensor responds to the instruction from the hand sensor 2 and the water flows. The reason is that cleaning is performed, and a time zone in which an imitation sound is generated is limited. In this operation mode, an imitation sound is generated in the small use time zone, and when the human body detection continues beyond the size determination time T1, that is, the running water washing can be performed by the user's will during the large use.

FIG. 9 is a time chart showing the operation according to the third aspect. The difference from the operation according to the time chart of FIG. 8 is that, when the human body detection sensor 1 is in the detection state, an imitation sound is generated for the first operation instruction by the hand sensor 2 and for the second and subsequent instructions. We wash with running water. In this operation mode, the running water can be washed before the size determination time T1 elapses, and the user can perform will washing when the small use is completed before the elapse of T1.

The time chart shown in FIG.
As an application of the time chart shown in FIG. 7, an example is such that an onomatopoeic sound is generated even when the human body detection sensor 1 is in a non-detection state. After the automatic cleaning after the human body detection sensor 1 is in the non-detection state or the manual cleaning by the hand sensor within the delay time T2, a dummy sound generation mode is automatically set, and the hand enters from the time when the user enters the room. A dummy sound is generated in response to an instruction from the holding sensor. In this time chart, running water washing by the hand sensor 2 can be performed only within the delay time T2 after the human body detection sensor 1 is in the non-detection state, and thus is effective in a toilet where running water washing due to mischief is frequent.

Further, the time chart shown in FIG. 11 is an example in which an imitation sound is generated even when the human body detection sensor 1 is not detecting, as an application of the time chart shown in FIG. Similar to the time chart shown in FIG. 10, the present embodiment is effective in a toilet where running water is frequently washed by mischief. The same application is also possible in the time chart shown in claim 3.

The memory in the controller 6 shown in FIG. 2 stores the operation modes of the time charts shown in FIGS. 7, 8, 9, 10, 11 and the like. By operating the changeover switch, the setting of the operation mode can be changed.

FIG. 6 is a perspective view of a toilet room in which the toilet cleaning apparatus of FIG. 1 is installed in a sitting-type Western-style toilet. In this case, in consideration of the operability of the user, the hand sensor 2
Is mounted on the wall in the form of a wireless remote control.

The present invention can be variously modified without being limited to the above embodiment. For example, the human body detecting means, the operation switch, the water supply means, the onomatopoeic sound generating means, and the control means are separately provided, and It is needless to say that the exchange of signals between them may be configured to be performed through a signal line, and wireless exchange is possible. The power supply may be a dry battery.

The water supply means may be an electrically operated low tank cleaning device, a high tank and an electrically operated drain valve, or the like. In addition, as notification means for notifying the toilet user of the operation target by the operation switch, in addition to the display by the light emitting element on the hand sensor shown in the embodiment, a liquid crystal display, a sound using a dummy sound generation means Alternatively, a method based on guidance by a user may be used.

[0027]

As described above, the present invention relates to a toilet cleaning device provided with an onomatopoeic sound generating means, wherein the human body detecting means is in the detecting state, or the human body detecting means is in the detecting state and in the detecting state. For a predetermined period of time after
Alternatively, during the period from the detection of the human body detection means to the first operation instruction being issued, the dummy sound generating means is activated in response to the operation instruction from the toilet user by the operation switch. However, when the user wants to eliminate the excretion sound, the onset sound can be reliably generated by the manual operation of the user's will. It is possible to perform washing with running water, and it is possible to prevent unnecessary washing with running water due to erroneous operation, mischief, etc., and it is possible to achieve a reliable water saving effect.

Further, by storing a plurality of time charts of the selected operation, the setting of the operation contents actually operated can be changed, so that the characteristics of the toilet user of the building in which the toilet cleaning device is installed. In accordance with the request of the owner or the owner, the operation contents of the toilet cleaning device can be adjusted while checking the water saving effect in each time chart.

In addition, in response to an operation instruction from the operation switch, there is provided notification means for notifying the toilet user of which one of the onset generator and the water supply means is to be operated at the time of operation. As a result, the toilet user can be provided with a sense of security, can be prevented from being misunderstood in operation, and can have a more reliable water-saving effect.
