Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a toilet bowl with an ozone deodorizing device that can effectively deodorize bad odors generated in the toilet bowl by ozone.

(B) Conventional technology In recent years, it has become known that ozone has a strong deodorizing effect due to its strong oxidizing effect. , Japanese Unexamined Patent Publication No. 60-31719 has proposed a toilet bowl with a built-in ozone generator.

In other words, the toilet bowl described in the same publication has an ozone deodorizing device built into the main body installed at the rear of the toilet seat, and the odor generated in the toilet bowl is sucked into the ozone deodorizing device through a suction port opened in the toilet bowl. The ozone generated by the discharge action of the ozone deodorizing device decomposes and deodorizes bad odors, and then the deodorized air can be discharged into the toilet.

(c) Problems to be solved by the invention However, such toilets still have the following problems to be solved.

That is, the ozone gas generated from the ozone generator installed in the toilet bowl changes significantly depending on changes in the temperature and humidity around the ozone generator.

Therefore, when the humidity is high, a sufficient amount of ozone is not generated from the ozone generating section, and deodorization by ozone cannot be performed effectively.

On the other hand, when the humidity is low, more ozone than necessary is generated from the ozone generator, and the odor is completely deodorized, but a large amount of untreated ozone is exhausted and The ozone concentration in the exhaust air becomes extremely high, causing problems with human safety such as headaches and eye irritation.

The present invention relates to a toilet bowl with an ozone deodorizing device that can solve the above problems.

(d) Means for Solving the Problems The present invention provides a toilet bowl with an ozone deodorizing device that deodorizes bad odors generated in the toilet bowl using an ozone deodorizing device. , an ozone deodorizing processing flow path with an outlet at the other end opened into the toilet space, an ozone generating section interposed within the ozone deodorizing processing flow path, and detecting the temperature and humidity within the ozone deodorizing processing flow path. The present invention relates to a toilet bowl with an ozone deodorizing device, characterized in that it is comprised of a temperature sensor, a humidity sensor, and a control section that controls an ozone generation section based on the outputs from each sensor.

(E) Function/Effect In the present invention, when defecating using this toilet bowl, the bad odor is sucked through the suction port opened in the interior space of the toilet bowl and reaches the ozone deodorization processing flow path, where the bad odor is generated from the ozone generating part. The air is deodorized by the deodorizing action of ozone, and the deodorized air is discharged from the outlet at the other end.

At this time, the temperature and humidity are sensed by each sensor in the ozone deodorizing flow path, and the output detected by each sensor is sent from each sensor to the control section to control the ozone generation section. , to adjust the amount of ozone generated.

In other words, when humidity is high, the amount of ozone from the ozone generator decreases, so the controller generates a sufficient amount of ozone from the ozone generator to deal with the bad odor, and reacts with a sufficient amount of ozone to generate ozone. can effectively deodorize.

On the other hand, when the humidity is low, more ozone is generated from the ozone generator than necessary, so the control unit suppresses the amount of ozone generated from the ozone generator to the necessary and sufficient amount, and uses a sufficient amount of ozone to remove bad odors. The ozone concentration in the exhaust gas after deodorization treatment can be maintained at a safe concentration.

In this way, ozone deodorization equipment cannot always generate a sufficient amount of ozone regardless of changes in temperature and humidity, so it is possible to improve the deodorization efficiency using ozone even in high humidity conditions. The ozone concentration in the exhaust gas after deodorization treatment can be kept below a certain value at all times, and safety to the human body can be sufficiently ensured.

(f) Examples The present invention will be specifically described below with reference to examples shown in the accompanying drawings.

Figures 1 and 2 show the overall structure of a toilet bowl A with an ozone deodorizing device according to the present invention. In addition, the ozone deodorizing device C is attached to the removable device 7E.

Furthermore, in addition to the ozone deodorizing device C, a private part cleaning device including a jet nozzle 10 and a low tank (none of which are shown) are integrally arranged inside the functional part casing B.

Furthermore, on one side of the rear part of the toilet seat R, it detects that the user has sat on the toilet seat R and that the user has left the toilet seat R,
As will be described later, a seating sensor S is provided which adjusts the amount of ozone generated from the ozone generating section H via the control section (2). On the other hand, on the other side of the rear part of the toilet seat R, as shown in Figure 1, a backup controller U is attached that can be used in the event that the remote controller P that controls the private parts cleaning device etc. attached to the wall fails. There is.

Hereinafter, with reference to FIG. 3, a specific configuration of the ozone deodorizing device C, which constitutes the gist of the toilet bowl A with an ozone deodorizing device according to the present invention, will be explained.

As shown in the figure, a long cylindrical body 11 is provided in a slightly inclined state in a mounting frame F that is detachably provided at the bottom of the functional part casing B, and the cylindrical body 11 is located inside the mounting frame F. A long ozone deodorization processing channel G is formed.

Both ends of the cylindrical body 11 form a suction part 12 and a discharge part 13, respectively. (See Figure 2)
It communicates with

On the other hand, the exhaust section 13 is connected to an exhaust blower 16,
The exhaust blower 16 has an exhaust port 17 formed on its lower surface.

Further, an ozonizer 18 with a heater 18a, which constitutes a main part of the ozone generating section 11, is disposed in the center of the ozone deodorizing flow path G formed in the cylindrical body 11.

The ozonizer 18 is connected to a high pressure generator 19 provided on the outer peripheral surface of the cylindrical body 11.
9 is connected to a control unit (2) installed on the mounting frame F.

With this configuration, the high-pressure generator 19 can apply a high voltage to the ozonizer 18 and generate ozone in the ozone deodorizing flow path G based on the drive output from the control unit 1.

Further, by heating the ozonizer 18 with the heater 18a, generation of ozone can be promoted.

Further, in the ozone deodorizing flow path G, an ozone mixing section 20 is formed downstream of the ozonizer 18.

The ozone mixing section 20 has semicircular rectifying plates 21 and 22 provided on the upper and lower surfaces of the ozone deodorizing flow path G at regular intervals in the axial direction.

Due to the current plates 21 and 22 and the current plate 12a provided at the bottom of the suction part 12 of the cylindrical body 11, the bad odor flowing from the ozone deodorizing device equipped toilet A into the ozone deodorizing process channel G is
It is effectively mixed with ozone generated from the ozonizer 18, and can promote the deodorizing effect in the ozone deodorizing process channel G.

In addition, in the ozone deodorization processing flow path G, on the downstream side of the ozone mixing section 20, there are first and second catalyst installation spaces 23 and 24.
are formed in series, and these catalyst installation spaces 23.2
A catalyst 2526, which can be replaced periodically, is removably disposed inside the catalyst 4.

The second catalyst installation space 24 is in communication with the IF output section 13.

The catalysts 25 and 26 may have various compositions and forms, and are preferably those in which a predetermined metal or metal oxide is supported on a carrier. These metals or metal oxides include manganese, iron, nickel, cobalt, silver, platinum, palladium, rhodium, chromium, molybdenum,
Examples include lead, tungsten, copper, vanadium, etc., which may be used alone or in combination.

As a carrier, alumina, silica, alumina-silica,
Examples include bentonite, diatomaceous earth, silicon carbide, titania, zirconia, magnesia, cobylite, mullite, activated carbon, etc., and more preferred are binary composite M oxides consisting of titanium-silicon and binary composite oxides consisting of titanium-zirconia. and ternary composite oxides consisting of titanium, silicon, and zirconia. Further, the shape of the catalyst is not particularly limited, and various shapes such as cylindrical shape, granular shape, cylindrical shape, and others can be applied.

Since these catalysts 25 and 26 promote the decomposition of ozone into oxygen and active oxygen, they can further promote the deodorizing effect caused by the above-mentioned mixing of ozone and bad odor.

Further, in the present invention, in such an ozone deodorizing device C,
A temperature sensor 27 and a humidity sensor 28 are disposed within the ozone deodorization processing channel G, and a control unit I is further connected to each sensor 27.2B.

As each sensor 27, 28, a commercially available humidity sensor, etc. can be used.

Then, each sensor 27 and 28 detects the temperature and humidity in the single-synth deodorizing processing flow path G, and sends the detection output to the control section (2), and via the control section (2), as described below, By controlling the ozone generator H, the amount of ozone generated can be adjusted.

In this embodiment, the duty ratio of the ozone generator H to the ozonizer 18 is changed by the control unit I based on the detection output from each sensor 27.2B, so that the ozonizer 18 We try to generate enough ozone for the appetizers.

That is, such an ozonizer 18 applies a pulsed voltage to an electrode to cause corona discharge at the same electrode, and each sensor 27,
Corona discharge at the electrodes is controlled by changing the pulse width (duty ratio) based on the detection output from 28.

Therefore, if the humidity in the ozone deodorizing flow path G is high,
Since the amount of ozone from the ozone generating section H decreases, the duty ratio of the ozonizer 18 is increased to generate a sufficient amount of ozone from the ozone generating section H to deal with the bad odor.

This necessary and sufficient amount of ozone reacts with the bad odor, so that ozone can effectively deodorize.

On the other hand, if the humidity in the ozone deodorization processing flow path G is low, more ozone than necessary is generated from the ozone generating section 11.
The duty ratio of the ozonizer 18 is made small to suppress the amount of ozone generated from the ozone generating part H to a necessary and sufficient amount.

Then, deodorization treatment is performed using a necessary and sufficient amount of ozone, and the ozone concentration in the exhaust gas after treatment can be maintained at an appropriate concentration.

In this way, the ozone deodorizing device C can always generate a certain amount of ozone to treat bad odors regardless of changes in temperature and humidity, so it improves the deodorizing efficiency with ozone even in high humidity conditions. The ozone concentration in the exhaust gas after deodorization treatment can be kept below a constant value at all times, and safety to the human body can be sufficiently ensured.

Furthermore, in this embodiment, each of the sensors 2T and 2B is attached to the side wall 12-1 of the suction part 12 in the ozone removal processing flow path G, and the temperature of the malodor sucked into the suction part 12 from the toilet main body T is measured. and humidity.

Then, each sensor 27 and 28 immediately detects the temperature and humidity of the odor coming from the toilet bowl body T, and
Accurate detection can be performed without being affected by high voltage etc. emitted from the ozonizer 18.

Hereinafter, with reference to FIG. 4, a description will be given of a method for deodorizing a bad odor generated in the toilet main body T using the ozone deodorizing apparatus c having the above configuration.

First, when a person sits on the toilet seat R of the toilet bowl A with an ozone deodorizing device, the seating sensor S installed behind the toilet seat R sends a detection output to the control section (■), and the exhaust blower 16 is activated by the drive output from the control section (■). At the same time, the high voltage generator 19 generates a high voltage and applies it to the ozonizer 1B to generate ozone in the ozone deodorizing flow path G.

As a result, the bad odor generated in the internal space Q of the toilet main body T is sucked into the ozone deodorization processing flow path G, and the ozone mixing part 2
At 0, it is effectively mixed with ozone and deodorized.

In addition, since catalysts 25 and 26 are disposed downstream of the ozone mixing section 20, the odor passing through the catalyst further promotes the mixing of the odor and ozone, further promoting the deodorizing process. It turns out.

After that, the completely deodorized exhaust gas is transferred to the exhaust section 13 and the tJF
Air is discharged from the air blower 16 into the toilet space through the exhaust port 17.

In addition, in this embodiment, a temperature sensor 27 and a humidity sensor 28 are installed in the ozone deodorization processing channel G, and the temperature and humidity in the channel G are detected by the sensors 27 and 28, and the detected value is is sent to the control section (2), and the amount of ozone generated by the ozone generation section (H) is adjusted by the control section (2).

Therefore, when the humidity is high, sufficient drops of ozone can be generated for effective deodorization, and when the humidity is low, the amount of ozone generated can be suppressed to maintain the ozone concentration in the exhaust gas at a constant value. Can be suppressed.

In particular, in the present invention, the ozone concentration in the D1 air is always below a certain value, for example, below the industrial hygiene allowable concentration of 0.1 ppa,
Furthermore, the ozone odor can be suppressed to less than o, ozpps, so that safety to the human body can be sufficiently ensured, and the discomfort caused by the ozone odor when using the toilet can be completely eliminated.

Further, by optimally controlling the amount of ozone generated, the amount of electric power required to drive the ozone generating section H can be reduced, and energy saving can be achieved.

Note that when the user leaves the seat after using the toilet, the seating sensor S detects this movement, and based on the detection output, the control unit
stops the operation of the exhaust blower 16 and the ozone generator H.
