Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilating structure for discharging a bad odor in a toilet, and a technique for exhausting a bad odor sucked and exhausted into a room without odor.

[0002]

2. Description of the Related Art Conventionally, odors generated in a toilet room are discharged to the outside of a room by a suction port connected to a ventilation fan provided on a ceiling or a wall of a room, or a ventilation fan buried directly in a wall. There is a type that discharges an odor from a suction port provided in a baseboard below a urinal, including a form that discharges an odor from the toilet. Further, there is a type in which a suction port is provided in a urinal body of a urinal or a Western-style toilet to discharge odor.

[0003] Further, since most of the ventilation fans are provided on an upper portion such as a ceiling surface of a toilet or on a wall surface, a bad odor from a drain port formed on a floor surface of the toilet is considered. Therefore, there is a problem that the bad odor from the drain port is accumulated in the toilet room, and the deodorization is not effectively performed. As a means for solving this problem, there is a device as shown in Japanese Utility Model Laid-Open No. 4-122778 shown in FIG. 8, in which a deodorizing hole is formed near the drain on the floor of the toilet. This is a method in which the odor around the drain port is sucked out and discharged to the outside through a ventilation fan.

As described above, a ventilator is often mounted on the ceiling in order to discharge the odor of the toilet, but such a ventilator cannot provide a sufficient effect. That is, the ventilator exhausts the odor drifting in the toilet room, and until the ventilation is completely completed, the user will feel the odor once diffused. In the case of a large public toilet, the frequency of use is high, and a small ventilator provided on the ceiling cannot eliminate the bad odor. Generally, the bad odor usually causes discomfort. Conventionally, the shape of the toilet bowl has been changed so that air flowing in the toilet chamber does not hit the toilet bowl to generate a vortex, that is, by suppressing the generation of the vortex, the purpose was to prevent the spread of offensive odor into the toilet chamber. Toilet bowls are also known, but are not a basic measure to prevent odors. When such a bad odor is always kept in a diffused state in the toilet room, the chemical substance causing the bad odor penetrates and penetrates into the side wall material and the ceiling plate of the toilet. Therefore, even after cleaning, it is no longer possible to cut off the stench of the toilet once soaked, and the toilet will always have a stench.

As described above, in the ventilation fan provided on the ceiling portion, the odor is diffused upward, and as a technique for preventing these drawbacks, a technique disclosed in FIG.
5 and JP-A-07-042384 shown in FIG. 10 are known in which a suction port for discharging odor is provided in the vicinity of a toilet to prevent odor from being diffused.

Further, a Japanese style toilet bowl for deodorizing as a prior art is known from Japanese Patent Application Laid-Open No. 61-49038. According to this technique, a hole is provided inside the upper end of a bowl portion of a toilet bowl, and this hole is connected to a deodorizing passage provided in the upper end to perform odor rising from the ball portion. As a technique for pointing out the deficiency of this technique and solving the problem, there is a technique such as Japanese Utility Model Publication No. 5-33585.

[0007]

However, in any of the above-mentioned technologies, the odor in the toilet room is exhausted to the outside by the finally connected ventilation fan. In addition, FIG.
In the Japanese style toilet bowl device, the bad odor sucked and deodorized is also discharged from the deodorizing pipe connected to the deodorizing passage, and the discharged odor is released as it is to the outside of the toilet room. It was still stinking around the building outside. The same applies to the method of directly exhausting air using a chimney type ventilation fan connected to the inside of the toilet tank, and the exhaust air from the ventilation fan has a bad smell around the building and is dense. In a building such as a house, especially when passing by the side, it gives a discomfort due to a bad smell.

As described above, in each of the above-described technologies,
Each of them relates to a deodorizing suction method, and the results of discharging the sucked odor are all the same, and there is no technique for treating the sucked odor. That is, in these conventional techniques, the odor in the toilet which is exhausted outdoors is directly discharged from the ventilation fan or the like, and the odor remains floating outdoors or in the wall. In addition, in the technology that combines inhalation and exhaust, the odor once exhausted outdoors is drawn back in, so the odor is simply circulated, and the toilet user smells the odor many times. You will always feel uncomfortable.

As described above, in the prior art, there is no ventilating structure in a toilet that treats and deodorizes the once-inhaled odor and discharges the odor to the outside, and the re-inhaled air is clean.

The present invention has been made in view of the above-mentioned problems in the prior art, and in order to solve the problems, the odor in the toilet room is efficiently discharged, and the discharged odor is constantly deodorized. An object of the present invention is to provide a ventilation structure in a toilet room and a system therefor, which can convert the air into clean air which hardly affects the human body, and to solve the above-mentioned drawbacks.

[0011]

As a result of various studies to solve the above problems, the above object can be effectively achieved by the present invention. That is, the ventilation structure in the toilet room according to the present invention has a concave ball portion long in the front-rear direction,
A Japanese-style toilet provided with a gold hidden portion provided at a front portion of the ball portion, wherein an odor suction opening duct for sucking and exhausting a bad odor of a surrounding is provided near a lower portion of the Japanese toilet body, and the odor suction opening duct is provided. Provided is a configuration characterized by improving a deodorizing function in a toilet room by disposing a humidifying device inside, and additionally installing a moisture removing filter, an activated carbon filter, and a deodorizing fan for suction and exhaust.

Further, in the ventilation structure in a toilet room according to the present invention, at least one or a plurality of air suction ports are attached to a facing portion of the odor suction opening duct which is located in a direction of air suction, and the outdoor or outdoor side is provided from the air suction port. The ventilation structure in the toilet room is characterized by taking in fresh air into the toilet room from outside and circulating the air in the toilet room.

[0013] Typically, a human body detection sensor is provided in the toilet room, and when the human body detection sensor detects a human body, it is controlled to instantaneously enter a ventilation operation and an air circulation operation. The above-mentioned various problems are solved by providing a toilet room ventilation structure.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the practice of the present invention, the odor in the room is always sucked by the odor suction opening duct 16 arranged in the vicinity of the lower part of the Japanese-style toilet bowl 10 at the time of use. A humidifier 17 is provided in the passage of the opening duct 16, and the humidifier 17 includes a heat generating mechanism for generating steam and a mechanism for injecting water droplets for steam. The indoor odor that is vaporized and passes through the inside of the humidifier contacts the vaporized water and is washed. The odor is simultaneously sucked while in contact with the steam, the water droplets are removed by a water removal filter 18 serving as a drainer, and the odor is discharged outside the toilet room through an activated carbon filter 19 disposed at the front or rear portion of the odor removal fan 20. You. Each device in the toilet room may be operated efficiently at the time of use so that it is instantly sucked from the generation of odor, and it is conceivable that a toilet user may turn on the switch for device operation arbitrarily. It is desirable that the humidifying device 17 is operated in advance, and it is appropriate that the humidifying device 17 is always operated.

At least one or a plurality of air suction ports 21 are provided on the opposite side of the odor suction opening duct 16 in the air suction direction, which also serves to replenish the air once discharged outdoors.
By installing air from outside, the insufficiency of closed-room toilets, such as high-insulation and high-confidentiality housing, is eliminated by allowing air from outside to flow. When the devices including the exhaust fan 20 are started, the human body detection sensor is activated when the device enters the toilet, and the devices can be automatically operated.

The ventilation structure in the toilet room of the present invention can be installed not only in a unit toilet but also in an existing toilet. The exhaust fan 20, the water removal filter 18 and the activated carbon filter 19 By performing the integral formation and fitting to the inner wall surface or the outer wall surface, each filter exchange and cleaning can be simplified.
