Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

However, it is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, and it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

In the embodiment or description of the present invention, the expression "direct water type" and/or "embedded type" is used, but this is an example, and the technical idea of the present invention is applicable to other types of toilet devices.

In addition, in representing the water tank, it is expressed as a small water tank, but this is only an example, and the technical idea of the present invention is applicable to medium and large water tanks.

As shown in FIGS. 2, 3 and 4 , the odor removal device for a direct flush (buried type) toilet according to the present invention includes a toilet body (10).

The toilet body 10 has a conventionally known structure as it is, and is configured to store a certain amount of water therein and discharge the excrement left by the user after toileting into the sewage tank.

* At this time, the present invention is provided with a small water tank (100).

The small water tank 100 is different from the existing water tank in that it is relatively small in size and uses direct water unlike the existing water tank.

Therefore, it is installed in a flexible position in terms of the installation space, and because it is installed under the rear partition, it is no different from a normal direct flush toilet (recessed type) in terms of the user's appearance.

In addition, as illustrated in FIGS. 3 to 8 , an aspirator 200 for generating bubbles while sucking and discharging air is built in the small water tank 100 .

Here, the aspirator 200 is the same as a known device, and is a generic term for a unit capable of sucking in a kind of air and discharging it to a liquid. It is a means for sucking the odor generated inside the main body 10 and dissolving it in the water stored in the small water tank 100 to remove it.

The aspirator 200 is installed in a part of the toilet body 10 and detects a person's body temperature or an electrostatic induction sensor for detecting a person, a touch sensor directly operated by a person, a pressure sensor operated by pressing the body weight of a person, or a human body temperature It is configured to operate for a certain period of time by receiving a detection signal from a temperature sensor or a proximity sensor that detects the approach of a person, or a sensor that detects a bad odor can be

And, the (small) water tank 100 is connected to the water supply pipe 20 and the connecting pipe 60 as a medium.

And, inside the small water tank 100, an aspirator 200, a water float 300 that passes air and blocks water, a water float 400 that keeps the amount of water below a certain amount, and water supply It is composed of a passage 102, a discharge pipe 103 for discharging purified air, and a check valve 500 for controlling the air in one direction.

The aspirator 200 sucks in the gas mixture (odor, etc.) generated during defecation from the inside of the toilet and discharges it to the small water tank 100 while dissolving it in dissolved water and then discharging it together with water.

At this time, the water float 300 is located on the lower side by gravity when the air passes, so it passes the air through the aspirator 200, and when the water comes up after defecation, it has a “∩” shape and rises by buoyancy. It blocks the passage to the aspirator 200 .

When the water is flushed after defecation, it is branched from the front end of the water bladder 300 , passes through the water supply passage 102 , and comes out of the water bladder discharge unit to fill the inside of the water tank 100 .

At this time, when the water level exceeds a certain level, the water level bladder 400 rises to block the water supply passage to prevent overflow of water.

The air purified through the aspirator 200 is discharged to the atmosphere through the discharge pipe 103 .

A check valve 500 is configured in the aspirator 200, so when positive (+) pressure is generated in the aspirator, air is discharged, and when negative (-) pressure is generated, the passage is blocked to supply water after toileting. After the water supply is stopped, the tank can be discharged by a siphon phenomenon.

The gas pipe 201 is installed lower than the discharge pipe 103, and serves as a passage to take the mixed gas generated during defecation to the aspirator 200, and the gas pipe 201 when the odor removal device is stopped. As the water filled in the water tank 100 and the dissolved smell are discharged through the connection pipe 60, it serves to lower the water level of the water tank.

As a means for achieving the above object, the present invention is installed in the buried space of a direct water type (recessed type) toilet, branched from the water supply pipe and spaced a certain distance apart, and installed at a higher position than the water supply pipe, and one side of the toilet sucks gas. A water tank equipped with a water float and a water float for controlling water supply on one side and a discharge pipe for discharging purified air; a connection pipe 60 branched in a T shape to the water supply pipe 20 and connected to the water tank; a water float that controls the gas to pass through and not to pass through the supplied water; A water bladder that passes the water supply below a certain water level and controls the water supply when the water level reaches a certain level; A discharge pipe that normally sends out purified air and discharges water when the water level is broken; A check valve for discharging positive pressure from the aspirator and blocking the negative pressure from the aspirator is provided.

At this time, there is also provided a odor removal device for a direct water type (buried type) toilet, characterized in that a solenoid valve that separately provides water supply is installed.

expand on the above.

water tank 100;

In the water tank, an aspirator 200 that generates bubbles while sucking in and discharging air, a water float 300 that passes air and blocks water, and a water float 400 that keeps the amount of water below a certain amount ), a water supply passage 102 and a discharge pipe 103 for discharging purified air, and a check valve 500 for controlling the air in one direction are provided,

The water float 300 is located on the lower side by gravity when air passes through it, so it passes the air through the aspirator 200, and when the water comes up after defecation, it has a “∩” shape and rises by buoyancy. Blocks the passage to the aspirator 200,

When the water is flushed after defecation, it is branched from the front end of the water bladder 300, passes through the water supply passage 102, and water flows out to the water bladder discharge part and is filled into the water tank 100,

At this time, when the water level is above a certain level, the water level bladder 400 rises to block the water supply passage to prevent overflow of water,

The air purified through the aspirator 200 is discharged to the atmosphere through the discharge pipe 103,

The gas pipe 201 is installed lower than the discharge pipe 103, and serves as a passage to take the mixed gas generated during defecation to the aspirator 200, and the gas pipe 201 when the odor removal device is stopped. It is an odor removal device for a toilet, characterized in that it serves to lower the water level in the water tank by discharging the water filled in the water tank 100 and the dissolved smell through the connection pipe 60 .

In another embodiment, without using the water supply passage 102 for water supply, the water pipe is connected to the separately piped solenoid valve inlet 106, and the solenoid valve 107 is opened as needed to open the water inlet pipe 108. Water is supplied to the water level bladder valve 105 through the water and used as purified water.

That is, the present invention has a dual structure in filling the odor-removing water so that water shortage or corruption does not occur in any case.

In addition, in the present invention, the intake pipe 110 is opened only when suction is performed to remove odor, and a gas-liquid control valve 310 is further installed on the pipe line of the intake pipe 110 so that it can be automatically drained in the event of an overflow. can be installed

The gas-liquid control valve 310 includes a valve pipe 312 in which the upper end of the intake pipe 110 is divided into two and fitted therebetween, and the valve pipe 312 as shown in FIGS. 14 to 16 . It includes a plurality of protruding guides 314 formed at intervals in the circumferential direction in the inner diameter, and a sealing hole 316 for opening and closing the intake pipe 110 while riding the protruding guide 314 and ascending and descending.

Thus, when the aspirator 200 operates and inhales, the sealing port 316 is sucked up and the intake pipe 110 is opened, so that the odor generated during the toilet can be sucked through the water supply pipe 20 .

And, when the odor removal water overflows, the closing port 316 continues to maintain the air intake pipe 110 sealed state as long as the aspirator 200 does not operate.

At this time, since the overflowed water flows toward the concave portion between the protrusion guides 314 and digs downward of the sealing sphere 316 having a truncated cone shape, the closing sphere 316 is lifted by buoyancy, and then the overflow the water is drained.

Therefore, the intake pipe 110 is normally maintained in a well-sealed state.

Here, the gas-liquid control valve 310 shown in the drawings is cut and illustrated for convenience of description.

On the other hand, in the present invention, without using a sol valve (SOL), as in the examples of FIGS. 17 to 19 , it may have a odor removal water filling and draining structure made of a combination of a swim bladder (BRE) and an opening/closing cylinder (CYL). .

As shown, the opening/closing cylinder CYL opens the drain port 112 by the water pressure discharged through the discharge pipe DR, and is elastically returned by the spring SPR to seal the drain hole 112.

That is, a cylinder housing 320 fixed to the inner wall surface of the small water tank 100 at an interval in front of the drain port 112 is disposed, and a disk piston 324 is built-in inside the cylinder housing 320, and the A sealing rod 322 for opening and closing the drain port 112 while protruding and retracting the cylinder housing 320 is integrally provided on one end surface of the disk piston 324, and the other end surface of the disk piston 324 and the small water tank A spring (SPR) is interposed between the inner wall surface of 100, and the end of the discharge pipe (DR) passes through the cylinder housing (320) and is disposed to be exposed between the sealing rod (322) and the disk piston (324) do.

Thus, when the aspirator 200 is operated, the gas is discharged through the discharge pipe DR. At this time, since the discharge pipe DR is disposed lower than the water level, the discharged gas pushes the water, and the water is the disk piston ( 324) is applied with water pressure, which causes the spring (SPR) to be pushed while being compressed.

Then, since the sealing rod 322 blocking the drain hole 112 is dropped, the drain hole 112 is opened for drainage.

This is the same water level as the upper end of the intake pipe 110 when the water fills up to the maximum, and the drain 112 is always located below the upper end of the intake pipe 110, so that smooth and natural drainage occurs.

Then, when the driving of the aspirator 200 is stopped, the sealing rod 322 seals the drain port 112 by the return force of the spring SPR.

And, when water runs out, it is refilled by the operation of the swim bladder (BRE) described above.

Therefore, even if the toilet is not used for a long period of time, since the odor removal water is continuously circulated, there is no problem of decay or deterioration, and it is possible to effectively remove the toilet odor.
