Description

TOILET BOWL APPARATUS AND OPERATION METHOD THEREOF

The present invention relates to a toilet device and an operating method thereof, and more particularly, to a toilet device and an operating method thereof, which can save washing water by automatically adjusting the amount of washing water discharged according to the type of toilet.

In general, about 13 liters of water is consumed for each flush of the toilet. At this time, assuming that one household flushes the toilet 10 to 15 times a day, the amount of water consumed by one household per day is about 130 to 195 liters, and the amount of water consumed by one household in one year is 40,000 liters. go beyond

Therefore, in general households, in order to reduce the amount of water consumed by the toilet, a 1.5 liter plastic bottle or a brick of equivalent volume is placed in the tank of the toilet. In this case, 1.5 liters of water can be saved per flushing, more than 15 liters of water can be saved per day, and about 5,000 liters of water can be saved for a year.

However, this conventional method is a method of reducing the amount of water without distinction between urine and feces. Therefore, because the water pressure when flushing is weak, it is difficult to pass the stool smoothly over the trap of the toilet only by flushing once, and water saving effect is not effective because water needs to be flushed several times until the stool is completely passed. In some cases, it is insignificant, and rather increases water consumption.

Therefore, a lot of research and development has been conducted on a method of varying the amount of water flowing down depending on the type of toilet, but methods up to now have divided the drainage structure into the toilet tank for stool and urine, and separate each of them from each other. It's just a level that is operated by another water flush button.

In this conventional method, since both a fecal drainage structure and a urine drainage structure must be installed inside the water tank of the toilet, the installation is complicated, and accordingly, there is a problem in that the cost is high. In addition, there is a problem that it is cumbersome to use because the user has to select and operate the flush button according to the toilet condition.

The technology underlying the present invention is disclosed in the following patent documents.

In addition to this, the structure of the operation unit 300 may vary.

On the other hand, when the operation unit 300 is provided with an elastic member and an air pump, air flowing in and out of the elastic member during operation of the operation unit 300 may be used to generate an airflow sound or vibration sound of a predetermined size, and thus , it is possible to quickly inform the user of whether the operation unit 300 is normally operated or not.

The detection unit 400 may include a gas sensor capable of detecting the concentration of gas generated from the bowel movement inside the bowl 110 . The gas sensor may be formed to detect the concentration of at least one of various types of gases that may be generated from the user's feces. For example, the gas sensor may be a gas sensor capable of detecting a concentration of a harmful gas including carbon dioxide, ammonia, and nitrogen oxide to a unit of about 100 ppm. Of course, the type of gas detectable by the gas sensor and the detection limit concentration may vary.

The detection unit 400 may be mounted on the upper rear side of the bowl 110 , and at least a portion thereof may be exposed inside the bowl 110 . The detection unit 400 may have a built-in battery or may receive power from an external source. When the concentration of the gas detected inside the bowl 110 exceeds a predetermined ppm, the detection unit 400 may output a signal to operate the operation unit 300 . That is, when the feces in the bowl 110 include feces, harmful gas may be generated from the feces, and the detection unit 400 may detect this and output a signal capable of operating the operation unit 300 . On the other hand, when the harmful gas disappears from the inside of the bowl 110 or the concentration of the harmful gas decreases after the water is flushed, the detection unit 400 may not output a signal for operating the operation unit 300 .

If the feces in the bowl 110 include only urine, noxious gas may be generated inside the bowl 110, or a relatively small amount of noxious gas may be generated compared to the feces. In this case, the detection unit 400 may not output a signal for the operation of the operation unit 300 .

The above-described detection unit 400 maintains a standby state while a signal, for example, a signal for operation of the detection unit 400, is not output from the detection unit 500 to be described later, and may operate when a signal is output from the detection unit 500, , when the signal output from the sensing unit 500 is stopped, the standby state may be maintained again. In the standby state, the power supplied to the detection unit 400 may be cut off or the supply of power may be minimized.

Meanwhile, the toilet device according to an embodiment of the present invention may include a sensing unit 500 . The sensing unit 500 may detect whether the user is seated on the body unit 100 , and may operate the detection unit 400 according to the result. That is, after the sensing unit 500 detects the user's seating, the detection unit 400 may operate.

The sensing unit 500 may include a pressure sensor capable of detecting the weight of the user on the body unit 100 . The sensing unit 500 may be installed at a predetermined position on the upper end of the bowl 110 .

The sensing unit 500 may come in contact with the seat 130 and sense a weight applied to the seat 130 by a user seated on the seat 130 . When the sensing unit 500 detects that the user is seated, it may output a signal for operating the detection unit 400 . In addition, when the user's seat is released and a predetermined time elapses, the sensing unit 500 may stop outputting a signal for the operation of the detection unit 400 .

In addition, the toilet apparatus according to an embodiment of the present invention may further include a controller 600 . In this case, the operation unit 300 , the detection unit 400 , and the detection unit 500 may transmit and receive signals to each other through the control unit 600 . In this case, the detection unit 400 may transmit the concentration value of the harmful gas detected inside the bowl 110 to the control unit 600 . The control unit 600 determines the type of stool corresponding to the condition information detected from the detection unit 400 by using the data and stores the reference state information inside the body unit 100 related to the type of defecation, and returns the result to the result. Accordingly, the operation of the operation unit 300 may be controlled.

Here, the internal reference state information of the body unit 100 related to the type of toilet may include a concentration value of the harmful gas generated from the user's toilet. In detail, the reference state information may include a concentration value of the harmful gas according to the type of feces. In this case, the type of defecation may include feces and urine. On the other hand, the reference state information may further include a concentration value of the harmful gas according to the state of feces during defecation, for example, viscosity and weight. The state information detected by the detection unit 400 may be a concentration value of the harmful gas inside the bowl 110 . In this case, the above-described state information may be a concentration value detected for each type of harmful gas, or may be a concentration value of any one selected from among the harmful gases.

The control unit 600 compares the state information detected from the detection unit 400 with the preset reference state information, extracts the type of feces from the reference state information closest to the state information, and puts the extracted type of feces into a bowl ( 110) It can be judged by the type of internal defecation. The control unit 600 may output a signal for the operation of the operation unit 300 when it is determined that the bowel movement includes feces.

On the other hand, when the control unit 600 can determine the state of the stool included in the toilet by using the state information and the reference state information, while outputting a signal for the operation of the operation unit 300, the volume member 330 A signal that can adjust the height of the rise can be output together. Accordingly, the control unit 600 controls the operation of the operation unit 300 to raise the volume member 330 relatively high when the viscosity of the stool is large and the weight is heavy, and when the viscosity of the stool is small and the weight is light, The operation of the operation unit 300 may be controlled to immerse the lower portion of the volume member 300 in the washing water at a predetermined height by raising the volume member 330 relatively low. That is, the level of the washing water inside the water tank 210 can be precisely adjusted according to the condition of the stool.

As described above, according to an embodiment of the present invention, when the user is seated on the seat 130, the detection unit 500 can operate the detection unit 400, the detection unit 400 can distinguish the type of toilet, , the operation unit 300 may automatically adjust the water supply amount of the washing water according to the type of toilet. That is, it is possible to automatically adjust the water supply amount of the washing water used for flushing according to the type of toilet.

At this time, even if the user operates the water flushing button 253 in the same manner, the amount of water supplied is automatically adjusted according to the type of toilet and used for flushing, so that the user can use the flush button 253 according to the type of toilet. Since it is not necessary to distinguish the operation method differently, it can be very easy to use.

7 is a flowchart of a method of operating a toilet device according to an embodiment of the present invention.

The method of operating a toilet device according to an embodiment of the present invention includes a process of detecting the state information of the inside of the body part 100 in which the user's toilet is accommodated to determine the type of toilet, and the interior of the body part 100 according to the type of toilet. It includes a process of adjusting the storage level of the washing water to be supplied to the toilet, and a process of supplying the washing water whose storage level is adjusted to the inside of the body part 100 and discharging the feces to the sewage pipe 20 connected to the body part 100 .

First, by detecting the internal state information of the user's defecation is accommodated in the body unit 100 to determine the type of defecation (S100). That is, the detection unit 400 detects the gas concentration inside the bowl 110 , and the control unit 600 may determine the type of feces from this.

Specifically, it is possible to detect the concentration of gas generated from the feces accommodated in the main body 100, and if the concentration of gas is greater than or equal to a preset value, feces may be judged as feces, and if less than that, feces may be judged as urine. This may be performed by the detection unit 400 and the control unit 600 .

At this time, the output unit 700 outputs the detection result of the detection unit 400 to the user, and if the type of stool recognized by the user and the detection result of the detection unit 400 are different from the detection result of the detection unit 400 using the input unit 800, It is also possible to correct the detection result.

Meanwhile, it is possible to detect whether the user is seated on the body unit 100 before the process of determining the type of toilet, and determine whether to perform the process of determining the type of toilet according to the detection result of whether the user is seated. For example, when the sensing unit 500 detects that the user is seated on the seat 130 , the detection unit 400 may be operated.

Thereafter, the storage level of the washing water to be supplied to the inside of the main body 100 is adjusted according to the type of defecation (S200). That is, when defecation is determined to be feces, the volume member 330 immersed in the washing water inside the water tank 210 is raised to separate from the washing water, the storage level of the washing water is lowered, and the water supply valve using the drop of the stored water level By operating 230, the washing water may be replenished and the storage level of the washing water may be restored. Meanwhile, when it is determined that the bowel movement is urine, the bulking member 330 may be continuously positioned under the water tank 210 .

On the other hand, along with this process, by using the variable trap 120 to adjust the height of the water rod, it is possible to adjust the level of the make-up water accommodated in the body portion 100 according to the type of toilet. That is, when the bowel movements include feces, the water level can be increased by increasing the height of the water rod. Accordingly, it is possible to prevent a small amount of washing water supplied to the bowl 110 from being discharged to the sewage pipe 20 before the water is flushed and wasted.

Thereafter, the washing water with the stored water level adjusted is supplied to the inside of the body part 100 , and the toilet is discharged to the sewage pipe 20 connected to the body part 100 . That is, by operating the water flush button 2530, the drain pipe 240 is opened, the washing water in the water tank 210 is supplied to the inside of the bowl 110, and the pressure is used to defecate the lower part of the bowl 110 and The make-up water may be pushed into the sewer pipe 20 .
