Hereinafter, the present disclosure will be described in more detail with reference to FIGS. 1 to 6.

1 is a perspective view of a toilet waste prevention apparatus 100 according to an embodiment of the present disclosure.

Referring to FIG. 1, the toilet waste prevention device 100 is coupled to the toilet 10, and a linear nozzle 115, a coupling member 110, a water supply pipe 130, a pipe joint 140, a flow sensor 150 ) Can be included.

The toilet 10 is a device through which the user can see the toilet, and is generally composed of a bowl-shaped body, a water tank 30, a water pipe 50, and a drain pipe. The toilet 10 has a structure in which water flows from the water tank 30 to the main body to guide the toilet to the drain pipe. There are various types of toilet bowls 10, and hereinafter, a description will be made based on a Western-style toilet seated toilet or a left toilet bowl, but may be applied to other types of toilet bowls.

A typical two-piece toilet is characterized by the fact that the toilet (10) and the water tank (30) are separated, and the water quickly descends through a siphon jet method, and the toilet (10) and the water tank are used in a one-piece toilet. (30) forms one body, and it has a structure in which water slowly rotates and descends in a vortex method.

In the case of the toilet 10, in particular, in the case of a two-piece toilet, it has the advantage of good cleaning power to flow water under strong pressure, but a liquid or fine solid containing foreign substances such as toilets inside the toilet 10 in the process of flowing water. Bounces around, bacteria, viruses, etc. may spread, and a device to prevent this may be required.

The linear nozzle 115 may provide a water curtain by spraying a spray liquid into the toilet 10.

In detail, the linear nozzle 115 sprays the jetting liquid through a linear jet formed in the interior direction of the toilet 10, and the linear jet may be disposed in the direction of the inner circumferential surface of the toilet 10, and the inside of the toilet 10 The high-pressure jet can be sprayed. The high-pressure jet of the linear nozzle 115 forms a water curtain covering the inner circumferential surface of the toilet 10, and the toilet 10 is caused by the water curtain even if liquid or fine solid particles splash upward from the lower surface of the water curtain as a reference. It can be swept down by doing it again. Through this, the water curtain can prevent liquid or fine solid particles from splashing and spreading to the upper surface when the water in the toilet 10 goes down.

Since the toilet 10 has a structure in which dirt, such as toilet, is accumulated in the lower part of the toilet 10, the toilet dirt outflow prevention device 100 is adjacent to the upper surface of the toilet 10 by the fixing member 110. By being disposed, it is possible to prevent the toilet waste leakage prevention device 100 from being contaminated. Accordingly, the linear nozzle 115 may reflect the spray liquid from the upper end of the toilet 10 to the lower end to form a water curtain.

The coupling member 110 may fix the linear nozzle 115 to the toilet 10. The coupling member 110 may be fixed to the toilet 10 in a single configuration such as a bracket, a screw, and a groove, or as a cover sheet having a shape covering the upper surface of the toilet 10 as shown in FIG. 1. , Having a protruding shape corresponding to the inner circumferential surface of the toilet 10, it may be seated and coupled to the inside of the toilet 10. The coupling member 110 having such a structure will be described with reference to FIGS. 2A and 2B.

The pipe joint 140 may connect the external water pipe 50 and the water supply pipe 130. The external water pipe 50 may be a water pipe connected to the water tank 30 of the toilet 10. Since the pipe joint 140 is a structure that supplies water from the water pipe of the conventional toilet 10 to the water supply pipe 130, it may be a T-shaped three-door joint.

The flow sensor 150 may sense the flow rate of the external water pipe 50. Since the toilet waste prevention apparatus 100 can be operated when water falls into the toilet 10 after the user has used it, the flow rate of the external water pipe 50 may be checked as a method of measuring this.

In general, the water tank 30 of the toilet 10 always stores a certain amount of water and discharges them into the toilet 10 when the water is flushed. In this case, when the quantity of the water tank 30 of the toilet 10 decreases, the external water pipe 50 of the toilet 10 immediately fills the water tank 30 with water, so the flow rate may fluctuate. Therefore, the flow sensor 150 may be connected to the external water pipe 50 or the pipe joint 140 to immediately sense the flow fluctuation and transmit it to the solenoid valve 160.

The solenoid valve 160 may open and close the water supply pipe 130 according to the sensing value of the flow sensor 150. The solenoid valve 160 is an electromagnetic valve, and may open or close the valve by raising or lowering the flange of the valve according to whether current is supplied or the amount of current. The solenoid valve 160 may be connected to the water supply pipe 130 or the pipe joint 140, or may be disposed inside the nozzle connector 116, as shown in FIG. 6.

The solenoid valve 160 opens the water supply pipe 130 when a flow rate fluctuation occurs according to the sensing value of the flow sensor 150 to supply the injection liquid from the water supply pipe 130 to the linear nozzle 115, and the linear nozzle 115 Can provide a water curtain by spraying a high-pressure spray liquid. Then, when the flow rate of the flow rate sensor 150 is stabilized again, the solenoid valve 160 may stop supply of the injection liquid to the linear nozzle 115 by closing the water supply pipe 130.

The toilet waste prevention device 100 may further include a disinfection device 135. The disinfection device 135 is connected to the external water pipe 50 to disinfect the running water inside. In the drawing, the disinfection device 135 is shown in a structure to disinfect running water delivered to the water tank 30 of the toilet 10, but in another embodiment, it is formed at the bottom of the pipe joint 140, and the water tank 30 In addition to flowing water delivered to ), the spray solution delivered to the linear nozzle 115 may also be sterilized.

2A is a plan view of a coupling member according to an embodiment of the present disclosure, and FIG. 2B is a side view of the coupling member 110 according to an embodiment of the present disclosure.

2A and 2B, an opening 111 may be formed in the coupling member 110.

The opening 111 is an open structure in which the linear nozzle 115 located inside the coupling member 110 can spray the liquid into the toilet bowl, and in detail, the coupling member having a shape covering the upper surface of the toilet 10 In (110), the linear nozzle 115 is located inside the coupling member 110, the injection port of the linear nozzle 115 is through the opening 111 of the inner surface of the coupling member 110 into the toilet (10). You can spray the spray liquid. In addition, the water supply pipe 130 connected to the linear nozzle 115 may be connected through a nozzle connector 116 formed on the side or inside of the coupling member 110.

The coupling member 110 may be detachable to the toilet 10. The coupling member 110 has a protruding shape corresponding to the shape of the inner circumferential surface of the toilet 10 as shown in FIG. 2B, and the protruding region may be mounted and fixed inside the toilet, and may be detachable.

As another example of the detachment method of the coupling member 110, a general toilet 10 has a structure that is coupled to the hinge at the lower surface of the coupling member 110 because the toilet seat 25 includes a hinge for detaching and detaching the toilet seat 25 on the upper surface, The upper surface may further include a separate hinge 125 to which the toilet seat 25 is rotatably coupled. Accordingly, the shape and shape of the toilet 10 are all different, but the structure of the hinge 125 to which the toilet seat 25 is attached and detached is standardized. 100) can be combined.

The coupling member 120 may include a plurality of pins, and may support the linear nozzle 115 in a region other than the region in which the linear nozzle 115 can be supported by the water supply pipe 130 as shown in FIG. 3. have.

According to the coupling member 120 including a plurality of pins, without being limited to the shape or structure of the upper surface of the toilet 10, the toilet dirt leakage prevention device 100 may be universally installed, and the coupling member 120 It is easy to clean the combined area, and can have various advantages such as maintaining the same height of the toilet seat 25 even if the toilet waste leakage prevention device 100 is installed.

4 is a side view of a toilet waste prevention apparatus 100 according to an embodiment of the present disclosure.

Referring to FIG. 4, the toilet waste prevention apparatus 100 may further include a filter 133 and a bucket removal apparatus 137.

The filter 133 may be provided inside the water supply pipe 130 to filter foreign substances, and the bucket removal device 137 may be connected to the external water pipe 50 to provide a bucket removal liquid.

The filter 133 is a device for maintaining the water quality of the water curtain sprayed through the linear nozzle 115, and may filter foreign substances and bacteria included in the spray liquid. In addition, in order to inject a high-pressure spray liquid, the linear nozzle 115 must have a narrow width, and there may be a risk of foreign substances being trapped. Correspondingly, the filter 133 may filter out foreign matter having a predetermined size or more to prevent the risk of clogging the linear nozzle 115, and improve the performance and durability of the toilet waste prevention apparatus 100.

Bucket removal device 137 may be located at the top of the pipe joint 140, as shown in Figure 4, or located at the top of the pipe joint 140 or the water supply pipe 130, the spray liquid delivered to the linear nozzle 115 You can remove the bucket. The backing is a foreign substance generated by the accumulation of salt inside the liquid, and the bucket removing device 137 can remove the bucket from the running water supplied to the water tank 30 or the linear nozzle 115 of the toilet 10 using the bucket removing liquid. have.

Therefore, the toilet waste prevention device 100 may include a filter 133 or a bucket removal device 137 to remove foreign substances of running water supplied to the water tank 30 or the linear nozzle 115, and It is possible to improve the performance and durability of the dirt leakage prevention device 100.

Referring to FIG. 4, the flow sensor 150 may be located below, or inside and above the pipe joint 140, and the solenoid valve 160 may be located at the middle of the water supply pipe 130, The water supply pipe 130 may be opened and closed by being connected to the flow sensor 150 with an electric wire. That is, the toilet waste prevention apparatus 100 according to various embodiments of the present disclosure may have various positions in which the flow sensor 150, the solenoid valve 160, and the filter 133 are disposed.

5A is a front view of the coupling member 110 according to an embodiment of the present disclosure, and FIG. 5B is a cross-sectional view of the coupling member 110 according to an embodiment of the present disclosure.

Referring to FIG. 5A, the toilet waste prevention apparatus 100 may include a ventilation port 170.

Vent 170 is formed in the coupling member 110, it is possible to absorb air from the inside of the toilet (10). The vent 170 may be formed in plural, and may be located on the top of the linear nozzle 115.

The vent 170 absorbs the air inside the toilet 10 and inhales liquid or fine solid particles that have passed through the water curtain to prevent them from being transferred to the outside of the toilet 10. Therefore, the toilet waste prevention apparatus 100 including the ventilation opening 170 can effectively prevent liquid or fine solid particles from spreading out of the toilet 10 due to an aerosol phenomenon.

In addition, since the ventilation opening 170 absorbs the air inside the toilet 10 and delivers it to the ventilation passage 177 to be described later, it is possible to prevent the smell of the inside of the toilet 10 from spreading to the outside of the toilet 10. .

In general toilets, a separate ventilation facility may be provided in the toilet, but if this is not provided, an odor may be emitted inside the toilet, causing discomfort to the user. In addition, ventilation equipment must be considered from the bathroom structure design process, and the cost can be high.

However, since the toilet waste prevention apparatus 100 of the present disclosure directly sucks air from the inside of the toilet 10 including the ventilation opening 170, and can block the odor from spreading to the outside of the toilet 10, the user immediately You can block odors from being transmitted to them. In addition, since the cost is lower than that of the toilet structure facility and can be additionally installed by the user as needed, it is possible to provide a comfortable toilet environment.

Referring to FIG. 5B, the linear nozzle 115 according to another embodiment of the present disclosure may have a structure in which a spray path is formed in a linear hose in a direction inside the toilet 10.

The linear nozzle 115 may be connected to the supply pipe 130 through a nozzle connector 116 embedded in the coupling member 110. The hose of the linear nozzle 115 may be formed to extend in a direction surrounding the toilet 10 inside the coupling member 110, and a high-pressure spray liquid into the toilet 10 through the injection path of the linear nozzle 115 Can be sprayed.

The width at which the linear nozzle 115 sprays the spray liquid may be 1 mm to 1.5 mm, and the spray liquid may be sprayed so as to be inclined 8 degrees in the lower direction with respect to the horizontal plane of the toilet 10.

When the same amount of the spray liquid is supplied through the water supply pipe 130, the spray pressure at which the linear nozzle 115 sprays the spray liquid may be increased as the spray width of the linear nozzle 115 is narrowed. When the injection pressure of the linear nozzle 115 is increased, the performance of the water curtain may be improved, and liquids and solids from the inside of the toilet 10 may be effectively prevented from going out. Therefore, the spray width of the linear nozzle 115 may be 1.5 mm or less. However, there is a risk that the linear nozzle 115 of 1 mm or less is blocked by foreign substances in the above-described spray liquid, and the performance of the water curtain may be deteriorated by an excessively thin water stream. Therefore, the spray width of the linear nozzle 115 may be 1 mm or more.

The injection port or the injection path of the linear nozzle 115 may be inclined to the bottom of the horizontal plane by about 8 degrees, and through this, the injection liquid may be sprayed while receiving gravity in the direction of gravity.In addition, the linear nozzle 115 is sanitary Because it is disposed adjacent to the upper part of the inner circumference of the toilet 10 due to the problem of problems, it is possible to effectively prevent liquid and solid suspended matter generated in the lower part of the bowl of the toilet 10, thereby providing a water curtain inside the toilet 10 efficiently. I can.

Each of the linear nozzles 115 may spray injection liquids in different directions. When the toilet 10 is flushed, water comes down from all directions on the inner circumference of the toilet 10, so an aerosol phenomenon may occur in all directions. Accordingly, each of the linear nozzles 115 sprays a spray liquid in different directions to provide a water curtain, and sprays a spray liquid having a predetermined water pressure or higher in all directions, thereby efficiently providing a water curtain.

6 is a plan view of a toilet waste prevention apparatus 100 according to an embodiment of the present disclosure.

Although not shown in the drawings, the toilet waste prevention apparatus 100 may include a water pump (not shown) to provide the injection pressure of the linear nozzle 115 and increase the effect of the water curtain. In this case, the water pump (not shown) may be supplied with power by the battery 165.

The ventilation fan 175 may generate an air flow through the ventilation port 170. Air inside the toilet 10 through the ventilation fan 175 may be delivered to the outside of the toilet through the ventilation opening 170 and the ventilation passage 177.

The ventilation fan 175 may be driven by a ventilation sensor (not shown) or a ventilation switch (not shown). Unlike the linear nozzle 115, the ventilation fan 175 may be driven at all times, and may include a ventilation sensor (not shown), which is a gravity sensor, to be controlled to be driven when the user sits on the toilet 10, or Can be driven by controlling the ventilation switch. Alternatively, since liquid or fine solid particles due to an aerosol phenomenon as well as odors are sucked through the ventilation opening 170, the effect of the water curtain can be enhanced by being driven in conjunction with the injection of the linear nozzle 115.

The ventilation passage 177 may guide air that has passed through the ventilation port 170 to the outside of the bathroom. One end of the ventilation passage 177 is connected to the ventilation port 170, and the other end is connected to a bathroom ventilation facility or the outside of a building, so that the air inside the toilet 10 is not transmitted to the user.

Meanwhile, in FIG. 1, it has been described that the water flow is detected based on the flow sensor, but this is only an example, and the solenoid valve 160 of the toilet waste prevention apparatus 100 of the present disclosure is driven by various operation controls. Can be.

In another embodiment of the present disclosure, the solenoid valve 160 senses whether the user is approaching or whether the toilet 10 is used through a proximity sensor (not shown), and before and after the toilet 10 is used ( 10) A water curtain can be provided inside. Alternatively, the solenoid valve 160 may detect whether the user is seated on the toilet seat or complete use through a pressure sensor (not shown), and provide a water curtain inside the toilet 10.

The toilet waste prevention apparatus 100 may include a proximity sensor (not shown) or a pressure sensor (not shown) and a flow rate sensor 150 together to more accurately detect a user's motion to provide a water curtain. For example, when a user approaches or sits on the toilet 10, a water curtain is provided for the purpose of primary internal cleaning, and when the use is terminated and water is flushed, the flow sensor 150 senses this and secondarily water It is possible to provide a water curtain for preventing an aerosol phenomenon that occurs while lowering the device.

A proximity sensor (not shown) or a pressure sensor (not shown) may be provided in the coupling member 110, and a water curtain can be provided by detecting a user without direct control by the user, thus providing comfort and convenience. I can.

As another embodiment of the present disclosure, the solenoid valve 160 may be controlled by including a nozzle switch (not shown). There may be situations where a water curtain is not required, and the required water curtain strength may vary depending on the type of toilet and the age of use, so the water curtain provision function is turned on/off through a nozzle switch (not shown). Or you can control the strength of the water curtain. In this case, sensors such as a nozzle switch (not shown) and a flow sensor 150 may be included together.

Of course, the toilet waste prevention apparatus 100 of the present disclosure may have an enlarged function, in which case, the enlarged spray liquid is provided to the linear nozzle 115 and may share an input substrate or a sensor.
