Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a deodorizing device for a toilet.

(Prior Art) Conventionally, as a deodorizing device, a device provided with an ozone generating device is known as described in, for example, Japanese Utility Model Publication No. 61-209665.

This deodorizing device decomposes the odor by mixing the ozone generated by the ozone generating device with the odor. However, this conventional device has a weak deodorizing performance and is effective for deodorizing a small space such as a refrigerator or a locker, but it is not sufficiently effective in a place where a strong odor is generated such as a toilet.

Therefore, a conventional device that uses a catalyst in addition to the ozone generator to allow the odor mixed with ozone to pass through the catalyst and to activate the chemical reaction between ozone and odor by the catalytic action of the catalyst to improve the deodorizing performance is also available. Are known.

(Problems to be Solved by the Invention) However, such a conventional device has the following problems.

When the temperature is low or the humidity is high, the activity of the catalyst is lowered, and the deodorizing ability is also lowered.

Since the secondary product formed after the odor is oxidatively decomposed is deposited on the surface of the catalyst, the activity of the catalyst is reduced and the deodorizing ability is reduced.

The present invention focuses on the above-mentioned conventional problems, and an object thereof is to provide a deodorizing device for a toilet, which can not only enhance the deodorizing performance but also stably secure the deodorizing performance.

(Means for Solving the Problem) In order to achieve the above object, the toilet deodorizing device of the present invention supplies a case in which an odor suction port and an air outlet are formed, and ozone is supplied into the case. An ozone generator,
The case includes a blower that forms an air flow from the odor suction port to the air outlet side, a catalyst provided near the air outlet of the case, and a heater that directly heats the catalyst. It is a thing.

(Operation) In the toilet deodorizing device of the present invention, the odor is sucked into the case from the odor suction port by the air flow generated by the blower. Then, the sucked odor is mixed with ozone supplied by the ozone generator in the case, and is chemically reacted and decomposed.

Here, when the odor is completely decomposed, the air becomes odorless, is warmed when passing through the catalyst, and is blown out of the case from the air outlet as odorless warm air.

In addition, if all the odors are not completely decomposed and remain, when passing through the catalyst, the remaining odors and ozone are chemically reacted by the catalytic action of the catalyst and completely decomposed, and the air blows out as odorless warm air. Will be blown out from. Further, the ozone left after the odor is completely decomposed is also decomposed into oxygen and blown out from the air outlet.

In this way, since odorless warm air is blown from the air outlet, it can be used as a heating device for a toilet.

Further, since the catalyst is heated by the heater, the activity of the catalyst is prevented from decreasing due to temperature decrease and humidity increase.

Further, since the secondary product formed after the odor is decomposed is blown off by the air flow, it is possible to prevent the secondary product from adsorbing on the surface of the catalyst and deteriorating the catalyst and stabilizing the active action of the catalyst. it can.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

First, the configuration of the first embodiment will be described with reference to FIGS. 1 and 2.

FIG. 1 is a plan view showing a toilet bowl 2 provided with the deodorizing device 1 of the present embodiment, 11 is a case, 12 is an ozone generator, 13 is a fan, 14 is a catalyst, and 15 is a heater.

The case 11 and the ozone generator 12 are provided adjacent to the rear positions of the toilet seat 21 and the toilet seat lid 22.

Further, the case 11 is formed with an odor suction port 111 and an air outlet 112, and the odor suction port 111 is opened in the internal space of the toilet 2.

The ozone generator 12 supplies ozone into the case 11, and the ejector 121 penetrates the side wall of the case 11 and is provided near the odor suction port 111.

The fan 13, the catalyst 14, and the heater 15 are provided near the air outlet 112 in the case. In these arrangements, the catalyst 14 is provided on the air outlet 112 side with the heater 15 interposed therebetween, and the fan 13 is provided on the opposite side.

Further, the fan 13 is installed in the case 11 so as to form an airflow from the odor suction port 111 to the air outlet 112 side.

Further, the heater 15 heats the surrounding air to generate a catalyst.
It directly heats 14, and, for example, a nichrome wire heater or the like is used.

Next, the operation of the embodiment will be described with reference to FIGS. 1 and 2. The arrows in the figure indicate the flow of odors.

According to the deodorizing apparatus 1 of the present embodiment, since the fan 13 generates an air flow from the odor suction port 111 to the air outlet 112 side in the case 11, the odor in the toilet bowl 2 is caused by the air flow. It is sucked into the case 11 from 111. On the other hand, since ozone is supplied into the case 11 from the ejector 121 of the ozone generator 12, the odor sucked from the odor suction port 111 is mixed with ozone in the case 11 and decomposed by a chemical reaction. .

Here, when the odor is completely decomposed, the air becomes odorless, and after being heated by the heater 15, passes through the catalyst 14 and is blown out of the case 11 from the air outlet 112 as the odorless warm air. .

Also, if all of the odor is not decomposed and remains, the catalyst
When passing through 14, the odor and ozone remaining due to the active action of the catalyst 14 chemically react and are completely decomposed, and are blown out from the air outlet 112 as odorless warm air.
Further, the ozone left after the odor is completely decomposed is also decomposed into oxygen and blown out from the air outlet 112.

In this way, since odorless warm air is blown out from the air outlet 112, it can be used as a toilet heating device.

Further, when the odor or odorless air warmed by the heater 15 passes through the catalyst 14, the catalyst 14 is also heated, so that the activity of the catalyst 14 is prevented from being lowered due to the temperature decrease and the humidity increase.

Furthermore, since the secondary product formed after the odor is decomposed is blown off by the air flow, the secondary product is prevented from depositing on the surface of the catalyst 14 and deteriorating the catalyst 14, and the active action of the catalyst 14 is stabilized. Can be made.

As described above, in the deodorizing device of this embodiment, not only can the deodorizing performance be enhanced by using the catalyst 14, but the deodorizing performance can be stabilized by heating the catalyst 14, and It can also be used as a heating device. That is, as the heating temperature of the heater 15, considering the heating of the catalyst 14 and the heating effect in the toilet,
40-50 degreeC is preferable. A guide plate or the like may be provided at the air outlet 112 to allow warm air to flow toward the feet of the person who sits on the toilet bowl 2.

Next, a second embodiment will be described with reference to FIG.

This embodiment is an example in which a heater 15 is sandwiched and catalysts 14, 14 are provided on both sides of the heater 15. Therefore, the catalyst 14, 14 is a heater 15
Are heated at the same time. Then, since ozone passes through the catalyst 14 twice and is activated twice, a higher deodorizing effect can be obtained.

Since the other configurations and operations are the same as those in the first embodiment, the same reference numerals are given to the drawings and the description thereof will be omitted.

FIG. 4 is a plan view showing another example of the heater 15a. The heater 15a is provided around the catalyst 14a and is configured to directly and efficiently heat the catalyst 14a. The type of the heater 15a may be a film heater, a ceramic heater, a posistor, or the like. Catalyst 14a as described above
By providing the heater 15a around the deodorizing device, the deodorizing device can be made more compact.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and even if there is a design change or the like within the scope not departing from the gist of the present invention, it is included in the present invention. Be done.

For example, in the embodiment, the example in which the deodorizing device is provided in the toilet bowl is shown, but it may be provided in another part such as a water tank.

Further, in the embodiment, the fan is used as the blower, but other devices may be used.

Further, the ozone generator may be provided in the case.

(Effect of the Invention) As described above, in the toilet deodorizing device of the present invention, not only the deodorizing performance can be enhanced by using the catalyst, but also the deodorizing performance is stabilized by heating the catalyst.
