Description

Water saving device of toilet bowl {Apparatus for water saving in a chamber pot}

The present invention relates to a water saving device of the toilet, and more particularly to a water saving device of the toilet so that water is made by automatically detecting the feces and urine and then adjusting the washing water correspondingly.

More specifically, the infrared sensor automatically detects the human body, and when the human body is detected, it sends out an etiquette sound so that the stool can be seen in a pleasant environment, and the feces and urine are automatically detected using the optical sensor. The present invention relates to a toilet water saving device capable of saving water by automatically controlling the amount of washing water according to a detected side.

In general, looking at the existing toilet water saving device, most of the structure is to control the amount of opening and closing of the washing water discharge valve is made to save water.

For example, the washing water discharge valve is opened and closed in two stages (urine in the first stage and feces in the second stage). Here, in order to selectively operate the washing water discharge valve operated in two stages, the user must selectively operate the push valve protruding from the outside. In other words, when the push valve is lightly pressed, the washing water discharge valve is operated in one stage, so that the washing water discharge valve is less open so that the washing water corresponding to the urine is discharged. Likewise, when the push valve is pushed downward, the washing water discharge valve is operated in two stages, thereby opening the washing water discharge valve a lot so that the washing water corresponding to the feces is released.

Such a toilet is a toilet in which a push valve protrudes to the outside and is operated by a user by hand.

In addition, there is a toilet in which the user manipulates the push valve protruding from the outside of the foot to control the discharge of the washing water. In this case, the water saving structure is similar to that of the well-known toilet bowl.

In addition, there is a toilet in which the user pulls the string to discharge the washing water stored in the washing water tank. In this case, the washing water discharge valve is operated by the user pulling the string to determine the drainage amount.

However, the various types of toilets in the related art, as is well-known, have to be operated by the user directly by the push valve, thereby causing inconvenience in accordance with the user's operation.

In addition, since the discharge amount of the washing water is controlled by the structural device of the machine, there is a disadvantage in that the accuracy is lacking compared to the electronic control, and if the washing water discharge valve is operated in one stage after the stool by the user's mistake of operation, it is not cleaned. Problems were also implicated.

In addition, the various types of toilets, as is well-known, has a disadvantage in that it is difficult to create a comfortable atmosphere because only a simple structure for discharging the washing water stored in the washing water tank when the user operates the push valve after viewing the toilet.

For example, stool sounds are often loud, which can be very unpleasant to people around you.

In this regard, the present invention is proposed to solve various problems occurring in the conventional toilet as described above.

In the above, the audio generating unit 200, the audio memory 107 for outputting the pre-stored audio according to the etiquette sound transmission signal output from the timer 106, and the audio output from the audio memory 107 is external An audio driver 108 that processes the audio driver 108 to be transmitted to the audio amplifier, an audio amplifier 109 for amplifying the audio output from the audio driver 108 to a predetermined level, and audio output from the audio amplifier 109 to the outside. Consists of a speaker 110 for transmitting.

In the water-saving device of the toilet according to the present invention configured as described above, when driving power is first supplied to the device by the power supply unit 126, the first transmitting / receiving amplifier 102 uses the oscillation frequency obtained from the first oscillator 101. FIG. To drive the infrared transmitter 103.

When the infrared ray transmitter 103 is driven, the infrared ray is projected, and the infrared ray is reflected on the human body when a person stands near the toilet or sits on the toilet to stool or urinate.

The infrared receiver 104 receives the infrared rays reflected from the human body as described above, converts the infrared rays into electrical signals, and transmits them to the first transmit / receive amplifier 102, and the first transmit / receive amplifier 102. Amplifies the received received signal to a predetermined level and outputs the amplified signal.

The first buffer 105 then buffers and digitizes the signal output from the first transmit / receive amplifier 102, and transmits the buffered signal to the timer 106.

In this case, when a person is not near the toilet, infrared rays are not incident on the infrared receiver 104.

On the other hand, the timer 106 recognizes that the human body is detected if the input signal lasts more than a predetermined time (about 2 seconds), generates a control signal for transmitting the etiquette sound and transmits it to the audio memory 107.

Here, about 2 seconds after the human body is detected, the timer 106 generates a control signal for transmitting the etiquette sound, the person may stay near the toilet for a while, and in this case, the etiquette sound may be generated or washed. Since the discharge should not be made, the purpose is to control the etiquette sound transmission only when the human body detection signal is maintained for about 2 seconds or more.

Next, when the control signal for transmitting the etiquette sound is applied from the timer 106, the audio memory 107 extracts the audio pre-built in the memory and delivers the audio signal to the audio driver 108. The audio stored in the memory may be music, a melody, or sound such as water or bird.

In this way, music, melody or sound is transmitted while the person is looking at the stool to create a pleasant atmosphere.

Next, the timer 106 maintains the current output state as long as the current signal is continuously maintained. If the current input signal is opposite to the previous state signal, that is, the toilet is finished. When a person leaves the toilet, there is no infrared light reflected by the infrared receiver 104, whereby a signal input to the timer 106 is also inputted with a signal opposite to the previous signal.

In this case, there is no control signal for transmitting the etiquette sound input to the audio memory 107, and the audio transmission is stopped.

Meanwhile, the second transmit / receive amplifier 112 drives the optical transmitter 113 using the oscillation frequency output from the second oscillator 111, and the driven optical transmitter 113 projects the light.

In addition, the optical receiver 114 receives the amount of light passing through the side, converts it into an electrical signal, and transmits it to the second transmit / receive amplifier 112.

That is, when a person peees, the light projected by the optical transmitter 113 passes through the urine and washing water almost to reach the optical receiver 114. In contrast, when the person sees the stool, the optical transmitter 113 The light projected at does not pass through the stool and is almost blocked.

Therefore, since the amount of light incident on the optical receiver 114 varies greatly depending on the stool or urine, the optical receiver 114 may detect the stool or urine, and generates an analog signal corresponding thereto according to the detected side.

The second transmit / receive amplifier 112 receiving the edge detection signal amplifies an input side detection signal to a predetermined level and outputs the second buffer 115 at the second transmit / receive amplifier 112. The output side detection signal is buffered and digitized and then transmitted to the multivibrator 116.

The multivibrator 116 maintains the current state when the detected side detection signal is a signal representing the stool, and in contrast, when the side detection signal is a signal indicating urine, a time suitable for urine is provided to the motor driving timer 118. Signal to be set.

Meanwhile, when the human body is not detected, the timer 106 has an output opposite to the previous output, and the third buffer 117 buffers the signal output from the timer 106 to drive the motor driving timer 118. To pass on.

When the human body is detected, the motor driving timer 118 maintains the current state since there is no signal input. Otherwise, when the human body is not detected, the driving signal is input, and thus, the motor driving control is performed according to the input driving signal. Generate a signal.

Here, since the motor drive control signal is set to the stool when there is no output from the multivibrator 116, the motor drive control signal is generated for a predetermined time so that the washing water corresponding to the stool can be discharged, and the multivibrator If there is an output from 116, the stool is urine, so that the washing water corresponding to the urine is discharged for a predetermined time (where the predetermined time is a time longer than the preset time for the stool). The motor drive control signal is generated to achieve this.

The motor driver 119 drives the motor for a predetermined time according to the motor driving control signal transmitted from the motor driving timer 118, and the washing water discharge valve 120 is opened based on the driving of the motor to discharge the washing water.

Thus, when feces or urine are automatically detected and the washing water discharge is automatically adjusted accordingly, saving water is possible.

On the other hand, the automatic water saving device as described above has no problem when the optical sensor for detecting feces and urine operates normally, but changes in menopausal change (meaning the loss of natural characteristics over time), aging, etc. As a result, the optical sensor may not operate normally.

In this case, the optical sensor may be replaced quickly, but before the optical sensor is replaced, the automatic water saving may be performed by using the remote controller 129 according to the present invention.

For example, the remote control 129 according to the present invention is provided with a stool selection key and a urine selection key, so that it can be operated near the toilet. If the light sensor is then found to have failed, the user artificially manipulates the stool or urine selection key.

Then, a signal corresponding to the selected key is generated by a high frequency generator (not shown in the figure) inside the remote controller 129, modulated at a high frequency, and radiated through the transmission antenna 130.

The receiving antenna 121 receives the RF signal radiated from the transmitting antenna 130, and the received RF signal is amplified to a predetermined level by the amplifier 123 after being processed by the RF receiving unit 122.

The received signal amplified by the amplifier 123 to a predetermined level is decoded by the decoder 124 and transmitted to the multivibrator 116 as a side discrimination signal.

Then, the multivibrator 116 recognizes the signal output from the decoder 124 in the same manner as the signal output from the second buffer 115 and transmits the corresponding signal to the motor driving timer 118.

Hereinafter, since operations of the third buffer 117, the motor driving timer 118, the motor driver 119, the washing water discharge valve 120, and the like are the same as the well-known operations, description thereof will be omitted.

On the other hand, the power source in the present invention uses the battery 125, the battery state detection unit 127 searches the output power of the power supply unit 126 to determine the state of the battery. For example, it is determined whether the battery is in a discharged state or a normal state, and the battery state display signal is transmitted to the battery state display unit 128 accordingly.

The battery state display unit 128 then visually displays the battery state according to the transmitted signal. For example, when the battery condition is normal using a light emitting diode, the green light blinks, whereas when the battery is discharged, the red light blinks to inform the manager of the battery status.

In addition, although not shown in the drawings of the present invention, the motor driver 119 may be built in a battery separately, the motor may be used to use a battery provided separately. Since the motor consumes more power than other parts, a separate motor driving battery can be built in to extend the battery replacement time.

In addition, although the water-saving device of the toilet according to the present invention has been described using the battery as a power source, a general commercial power source may be used.

In this case, if the power supply unit 126 further includes an AC / DC converter, it is possible to easily use a commercial AC power supplied from the outside.

That is, the light transmitter 113 is driven to project light, and the light transmitted through the side is detected using the light receiver 114.

Then, in step S18, the signal detected by the optical receiver 114 is analyzed to determine whether it is feces or urine.

If the result of the determination is a stool, the washing water discharge valve is controlled to discharge the amount of washing water set to the stool in step S19, otherwise, if the determination result is urine, the washing water to discharge the amount of washing water set to urine in step S20 To control the discharge valve.

By doing so, the optimal washing water is discharged in accordance with feces or urine, thereby saving water.
