Description

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

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet water saving apparatus, and more particularly, to a toilet toilet water saving apparatus that automatically detects feces and urine and adjusts the washing water accordingly.

In more detail, the infrared sensor automatically detects the human body, and when the human body is detected, the sound is transmitted so that the stool can be seen in a comfortable environment, and the feces and urine are automatically detected using a timer or a gas sensor. The present invention relates to a toilet water saving device and a method for saving water by automatically controlling the amount of washing water according to the sensed edge.

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 discharged.

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 operates the push valve protruding from the outside to adjust the discharge of the washing water, and the water saving structure in this case 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 amount of washing water discharged 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 user's mistake of operation, the washing cannot be 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, the stool often sounds loud, which can be very unpleasant to people around you.

Accordingly, the present invention has been proposed to solve various problems occurring in the conventional toilet as described above,

The control unit 120 controls the level of the infrared signal received at the same time and converts and amplifies the received infrared signal into an analog signal and outputs a human body detection signal.

In addition, if it is determined that the human body is detected by analyzing the signal output from the signal detecting unit 150, the reference numeral 200 drives an internal timer, searches for a time value output from the timer, and then the first setting time or more. When the elapsed time to generate a first control signal for sound generation, by comparing the time value and the second set time to determine feces or urine according to the size of the case, and to control the amount of washing water according to the type of the determined side A control unit for generating a second control signal and a third control signal for displaying a detection state is shown.

In addition, reference numeral 160 denotes a sound generating driver that generates sound and transmits the sound to the speaker 170 according to the first control signal output from the controller 200, and reference numeral 180 denotes a first output signal from the controller 200. 2 represents a motor driver for controlling the opening and closing time of the washing water discharge valve by driving the motor 190 for a time set corresponding to the control signal, and reference numeral 400 denotes a signal for arbitrarily controlling sound and operation functions according to a user's operation. A sound and operation function controller for inputting to the controller 200 is shown.

In addition, reference numeral 500 denotes a fecal drainage control unit for inputting a signal for manually adjusting the stool drainage and urine drainage according to the user's manual operation, reference numeral 610 denotes a power level obtained from the battery a predetermined level The power supply unit converts to DC power and supplies driving power to each stage of the device requiring power, and reference numeral 620 detects a current amount of power supplied from the power supply unit 610 to detect a state of the battery. A battery state detection unit to be transmitted to the control unit 200 is indicated, and reference numeral 300 denotes a detection indicator for visually displaying a human body detection state and a battery state according to a third control signal output from the control unit 200.

In the first embodiment of the water-saving device of the toilet according to the present invention configured as described above, first, the power supply unit 610 converts the voltage discharged from the battery mounted therein into a predetermined DC voltage to supply driving power to the water-saving device. . Here, the power supply unit 610 may receive commercial AC power in addition to the battery and convert it into a predetermined DC voltage to supply driving power to the water saving device.

When the power is supplied, the controller 200 drives the infrared driver 130 to detect the human body, and the infrared driver 130 drives the infrared transmitter 110 under the control of the controller 200. When the infrared transmitter 110 is driven, the infrared ray is projected, and the infrared rays are reflected by the human body when the person stands near the toilet (within the sensing distance) or sits on the toilet to stool or stool.

In this regard, the infrared receiver 120 receives the infrared rays reflected from the human body as described above, converts them into electrical signals, and transmits them to the signal detector 150, and the signal detector 150 is the distance sensitivity controller. According to the sensitivity control signal output from the 140 adjusts the level of the infrared signal received by the infrared receiver 120 and at the same time converts and amplifies the received infrared signal to an analog signal and transmits it to the controller 200 as a human body detection signal. do.

If the person is not near the toilet (within the sensing distance), the infrared ray is not incident to the infrared receiver 120.

On the other hand, if it is determined that the human body is detected by analyzing the input signal, the controller 200 drives an internal timer, and elapses of a first predetermined time (about 2 seconds) based on a time value output from the timer. Check whether or not. As a result, when the human body is detected for more than the first predetermined time, a control signal for sound transmission is generated and transmitted to the sound generating driver 160.

Here, about 2 seconds after the detection of the human body to generate a control signal for sound transmission, the person may stay for a short time near the toilet and just go, in this case, so that no sound generation or washing water discharge, For the sake of accuracy, this is to control the sound transmission only when the human detection signal is maintained for about 2 seconds or more.

Next, the sound generating driver 160 converts the audio data pre-built in the voice chip IC into an analog audio signal corresponding to the control signal for sound transmission output from the control unit 200 as an address. Then, amplified to a predetermined level through an audio amplifier and sent out to the outside through the speaker 170.

Here, the audio data stored in the voice chip (IC) is varied, such as music, melody, water sound, bird sound, children's nursery rhyme or cartoon movie theme songs, preaching music for preaching. It also simply replaces only the voice chip (IC) to listen to the desired audio.

In this way, a person sends out music, melody or sound while viewing the stools to create a pleasant atmosphere.

Next, the controller 200 maintains the current output state as long as the human body detection signal is continuously maintained. If the human body is not detected, the controller 200 sets a preset time value output from the internal timer at that time. The feces or urine will be judged by comparison with the set time (for example, 1 minute).

That is, when the time value is less than the second predetermined time at the time when the human body is not detected, it is determined as urine, and the motor drive control signal (second control signal) so that only the washing water set in advance corresponding to the urine can be discharged. Will occur).

In addition, when the time value is greater than the second predetermined time, the determination is made with a stool, and a motor driving control signal (second control signal) is generated so that only the washing water set in advance corresponding to the stool is discharged.

For example, in the automatic mode, the water saving function is performed by the automatic water saving operation as described above, and in the manual mode, the water saving function is performed by operating corresponding to the key operated by the user without using a timer.

On the other hand, the power in the present invention uses a battery, the battery state detection unit 620 determines the state of the battery by searching the output power of the power supply unit 610. For example, it is determined whether the battery is in a discharged state or a normal state, and a battery state detection signal is transmitted to the controller 200 accordingly.

Then, the control unit 200 transmits a control signal for visually displaying the battery state to the detection indicator 300, the detection indicator 300 visually displays the battery state, so that a user (or an administrator) can easily This allows you to know the condition of the battery and when to replace it.

When the power is supplied, the controller 200 drives the infrared driver 130 to detect the human body, and the infrared driver 130 drives the infrared transmitter 110 under the control of the controller 200. When the infrared transmitter 110 is driven, the infrared ray is projected, and the infrared rays are reflected by the human body when the person stands near the toilet (within the sensing distance) or sits on the toilet to stool or stool.

As a result, when the human body is detected, the internal timer is driven in step S104, based on the time value output from the timer. When the sensor detects more than the first preset time (about 2 seconds), it generates sound. Here, the first setting time is proposed as 2 seconds, which is not limited, but only one embodiment.

In addition, if the human body is not detected within two seconds after the check result, the driven timer is turned off. This is to prevent the drainage of the wash water when a person stays in the toilet for a while and just goes without seeing it.

Next, the infrared sensor is driven again in step S105, and it is checked in step S106 whether a human body is detected. If the human body is detected as a result of this check, the process moves to step S107 to accumulate the body detection time, and then moves to step S105 described above.

On the other hand, as a result of determining whether the human body is detected in step S106, if no human body is detected, the process proceeds to step S108 and compares the accumulated human body detection time with a preset second set time (1 minute), depending on whether or not Determine feces or urine.

That is, if the accumulated human detection time is less than the second set time, it is determined as urine, and the flow moves to step S109 to check the amount of washing water set in advance by urine.

According to the second embodiment of the water-saving method of the toilet according to the present invention, the water-saving function is automatically performed by using the feces detecting sensor.

That is, as shown in Fig. 5, it is checked whether power is supplied in step S201, and as a result, if power is supplied, the infrared sensor (infrared transmitter and infrared receiver) is driven in step S202.

Thereafter, in step S203, the output of the infrared sensor (infrared receiver) is searched to check whether a human body is detected. As a result, when the human body is detected, sound is generated in step S204. Here, the sound generation has a slight delay time (about 2 seconds) than occurs at the same time as detecting the human body, and controls to generate sound only when the human body is continuously detected for 2 seconds or more. This is to prevent the drainage of the wash water when a person stays in the toilet for a while and just goes without seeing it.

Next, the infrared sensor is driven again in step S205, and it is checked in step S206 whether a human body is detected. If the human body is detected as a result of this check, the process moves to step S205 to perform a human body detecting operation.

On the other hand, as a result of determining whether the human body is detected in step S206, if no human body is detected, the process moves to step S207 to operate the feces detection sensor.

Then, in step S208, it is checked whether the smell (gas) generated during feces is detected.

For example, if the stool detection sensor detects gas generated during stool, a stool detection signal is present. If the gas cannot be detected (when urine is seen), the stool detection signal does not exist. This principle makes it possible to distinguish feces or urine.

On the other hand, if the gas is not detected as a result of the checking in step S208, the flow moves to step S209 to determine the urine, and the amount of washing water set in advance by the urine is checked.

Then, in step S210, the motor is controlled to discharge the washing water corresponding to the checked amount of urine washing water.

If the human body is not detected here, the sound is also stopped.

On the other hand, if the gas is detected as a result of the checking in step S208, the process moves to step S211 to determine the feces, and checks the amount of washing water preset in the feces.

In addition, the motor is controlled to discharge the washing water corresponding to the amount of fecal washing water checked in step S212.

This saves water by discharging the optimal washing water according to feces or urine.

6 is a flowchart illustrating a third embodiment of a water-saving method of the toilet according to the present invention.

As shown in the drawing, driving power to an infrared sensor (infrared transmitter and infrared receiver) for sensing a human body and determining whether the human body is detected according to whether or not infrared rays are received (S301 to S303); If the human body is detected as a result of the determination, driving a sound generating driver to generate sound (S304); Driving the infrared sensor again after the sound generation and determining whether or not the human body is detected, and accumulating the human body detection time when the human body is detected as a result (S305 to S307); Determining whether the human body is detected and determining whether the accumulated human body detection time is a stool time or a urine time when the human body is not detected (S308); If the human body detection time is the urine time as a result of the check, judging as the urine, controlling the washing water discharge valve so as to discharge only a predetermined amount of the washing water corresponding to the urine after stopping the sound generation (S309 ~ S310) and ; Driving the stool detection sensor when the human detection time is the stool time as a result of the checking; Analyzing the signal output from the stool detection sensor to determine whether the stool, and if the determination is determined to be urine, the process returns to the step (S309), if the stool is determined to stop the generation of sound and the predetermined amount corresponding to the stool And controlling the washing water discharge valve to discharge only the washing water (S313 to S314).

In the third embodiment of the water-saving method of the toilet according to the present invention made as described above, the water-saving function is automatically performed using a stool detection sensor.

That is, as shown in Fig. 6, it is checked whether power is supplied in step S301, and if power is supplied as a result, the infrared sensors (infrared transmitter and infrared receiver) are driven in step S302.

Thereafter, in step S303, the output of the infrared sensor (infrared receiver) is searched to check whether a human body is detected, and as a result, when the human body is detected, sound is generated in step S304. Here, the sound generation has a slight delay time (about 2 seconds) than occurs at the same time as detecting the human body, and controls to generate sound only when the human body is continuously detected for 2 seconds or more. This is to prevent the drainage of the wash water when a person stays in the toilet for a while and just goes without seeing it.

Next, the infrared sensor is driven again in step S305, and it is checked whether a human body is detected in step S306. If the human body is detected as a result of this check, the process moves to step S307 to accumulate the body detection time, and the process moves to the above-described step S305 to perform a human body detecting operation.

On the other hand, as a result of determining whether the human body is detected in step S306, if no human body is detected, the process moves to step S307 to determine whether the accumulated human body detection time is urine time or feces time.

Herein, the present invention sets the boundary between urine time and fecal time to 1 minute. For example, if the accumulated human body detection time is within 1 minute, it is determined as the urine time. Otherwise, if the accumulated human body detection time is 1 minute or more, it is determined as the stool time.

In addition, although the reference time for determining the stool time or the urine time is set to 1 minute, this is not limited and may be set variably according to race, characteristics, and the like.

On the other hand, if the accumulated human detection time is less than 1 minute as a result of the check, it is determined by the urine time, go to step S309 to determine the urine, and check the amount of washing water set in advance with urine.

In operation S310, the motor is controlled to discharge the washing water corresponding to the checked amount of urine washing water.

If the human body is not detected here, the sound is also stopped.

In addition, if the accumulated human body detection time is 1 minute or more as a result of the check, it is determined as the stool time, and moves to step S311 to drive the stool detection sensor.

Thereafter, in step S312, the output signal of the feces detecting sensor is analyzed to determine whether urine or feces are present.

That is, it is checked whether the smell (gas) generated during feces is detected using the feces detecting sensor.

For example, if the stool detection sensor detects gas generated during stool, a stool detection signal is present. If the gas cannot be detected (when urine is seen), the stool detection signal does not exist. This principle makes it possible to distinguish feces or urine.

On the other hand, if the gas is not detected as a result of the check in step S312 to go to step S309 to determine the urine, the following operation is performed.

In this case, the user stayed in the toilet for as long as the stool time, but actually did not see the stool, because the urine state, judging by the urine to control the washing water.

In addition, when the gas is detected as a result of the check in step S312 (if smell is detected), the process moves to step S313 to determine the feces and checks the amount of washing water set in advance in the feces.

Then, the motor is controlled to discharge the washing water corresponding to the amount of the feces washing water checked in step S314.

This saves water by discharging the optimal washing water according to feces or urine.

According to the above-described "water saving device and method of the toilet" of the present invention, by automatically detecting the human body, detecting feces or urine, and automatically controlling the washing water discharge valve correspondingly, saving water is possible as well. To facilitate the use of the toilet.

In addition, since it automatically detects the human body, feces / urine detection, washing water discharge control, precise washing water discharge control is possible.

In addition, since the sound is transmitted during the toilet, there is an advantage that can create a pleasant atmosphere.
