Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a deodorizing device for purifying malodorous components such as hydrogen sulfide, ammonia, various mercaptans, and amines.

BACKGROUND OF THE INVENTION In recent years, deodorizing devices have been introduced into housing equipment reflecting the trend toward cleanliness, and among these, toilet bowls equipped with deodorizing devices have been proposed in toilets, which are the source of bad odors.

This type of toilet bowl with a deodorizing function is known, for example, from Japanese Patent Application Laid-open No. 63-1
There is one disclosed in Japanese Patent No. 4672.

Its configuration will be explained based on FIG. In the same figure, 1
is a deodorizing device, which includes an air blower 6 consisting of a fan motor inside a duct 5 having an inlet 3 opening to the rear or side of the inside of the toilet bowl 2 and an outlet 4 facing into the toilet, and a blower 6 for storing malodorous components. An adsorption member 7 made of activated carbon is provided.

In the above configuration, when the blower 116 is driven, an air flow is generated from the inlet 3 to the outlet 4, and the air containing malodorous components during defecation is sucked in from the inlet 2, and when it passes through the adsorption member 7, the malodorous components are adsorbed. It is purified and discharged into the toilet from the discharge port 4.

Problems to be Solved by the Invention Since such conventional deodorizing devices use activated carbon as an adsorption member, the amount of malodorous components adsorbed is limited. Therefore, when the saturated adsorption amount is reached, the deodorizing effect disappears and it is necessary to replace it. Furthermore, when the temperature inside the toilet rises, some odor components may be desorbed, resulting in an increase in odor and discomfort. In addition, in order to maintain the deodorizing effect over a long period of time, the saturated adsorption amount must be increased, that is, the volume of the adsorption member must be increased, which leads to an increase in the size of the entire device.

The present invention solves the above problems, and aims to provide a small-sized deodorizing device that does not require replacement of the adsorption member.

Means for Solving the Problems In order to achieve the above objects, the present invention provides an adsorption member that is disposed in a duct having an inlet, an outlet, and a blower, and that adsorbs and holds malodorous components, and an adsorption member that is adsorbed by the adsorption member. a desorption member for forcibly desorbing malodorous components; a bypass pipe having an opening on the downstream side of the adsorption member and the other end of which is connected to water in a water storage container; and a bypass pipe disposed in a flow path of the bypass pipe. The pump includes a damper that opens and closes the bypass pipe, and a control circuit that controls the blower, the detachable member, the pump, and the damper.

Function The desorption device of the present invention has the above-mentioned configuration. During deodorization, the blower sucks in malodorous components, the adsorption member adsorbs and purifies them, deodorizes for a predetermined period, and before reaching the saturated adsorption amount, operates the damper to open the bypass pipe. At the same time, the desorption member and the pump are operated to desorb the malodorous components adsorbed by the adsorption member and dissolve them by bubbling them into the water in the water storage container through the bypass pipe. Here, the malodorous components are easily dissolved in water and can be efficiently treated, and the wastewater in which the malodorous components are dissolved is disposed of, for example, as sewage.

This automatically regenerates the adsorption member and processes malodorous components, making it possible to maintain the deodorizing effect for a long period of time without replacing the adsorption member.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. FIG. 1 is a cross-sectional view of a deodorizing device according to the present invention, showing an embodiment of the deodorizing device in a toilet bowl.

In the figure, 8 is a deodorizing device, and inside a duct 11 provided with a suction port 9 and a discharge port 10, there is a blower 12 and an adsorption member 13 made of activated carbon that physically adsorbs malodorous components. A desorption member I4 consisting of a heater that heats malodorous components to desorb them is provided.

Reference numeral 15 denotes a bypass pipe, which has an opening 16 on the downstream side of the adsorption member 13, and the other end is opened into the water of a water storage container 17, which is a toilet bowl. A pump 18 is provided for discharging and bubbling water into the water.

19 is a damper for opening and closing the opening 1G of the bypass pipe 15. In addition, 20 is an air blower 1112, and a detachable member 1.
4. A control circuit that controls the pump 18 and damper 19. When the seat switch 21 is turned on, the blower 12 is operated to perform deodorization, and a built-in timer (not shown) reaches the saturated adsorption amount of the adsorption member 13. The damper 19 is automatically operated at a predetermined time before the discharge port lO is closed, the bypass pipe 15 is opened, and at the same time the desorption member 1 is
4 to heat the adsorption member 13 and the pump 1
Operate the sun to bubble odor components into the water.

In the above configuration, the operation will be explained next. When you sit on the toilet bowl when defecating, the seat switch 21 is turned on and the blower 12 is turned on.
operates, a large flow of air is generated from the suction port 9 to the discharge port IO, and malodorous components during defecation are sucked through the suction port 9 and physically adsorbed onto the adsorption member 13. The purified air is discharged into the toilet through the outlet 10.

Next, regeneration of the adsorption member 13 will be explained. Adsorption member 1
After a predetermined period of time has elapsed until the saturated adsorption amount is not reached according to the size (adsorption area) of No. 3, the # control circuit 20 operates, the damper 19 operates, the discharge port 10 is closed, and the bypass pipe 15 is opened. At the same time, electricity is applied to the detachable member 14 to heat the adsorption member 13. At this time, some malodorous components are desorbed at a relatively low temperature and some components are not desorbed unless heated to a high temperature, but they can be completely desorbed by heating to about 300'C or higher.

In addition, when activated carbon is used as the adsorption member 13, approximately 400
If the temperature exceeds .degree. C., it will burn, so it is necessary to control the temperature of the detachable member 14. The desorbed malodorous components are sucked out by the pump 18 for a predetermined period of time, and then passed through the bypass pipe 15 to the water storage container (
Bubbling occurs in the water of toilet bowl H7.

The malodorous components are easily dissolved in water, but even if they are not dissolved and emitted into the toilet bowl again, they will be sucked in again from the suction port 9 and bubbled. Sewage with malodorous components dissolved in it is disposed of into the sewage system along with feces when the toilet is used.

In the above explanation, an example was described in which the saturated adsorption amount of the adsorption member 13 is predicted and the desorption/regeneration operation is automatically performed by the control circuit 20. You may also perform an action.

As described above, according to this embodiment, deodorization is performed with a large air volume while reducing pressure loss through physical adsorption to the adsorption member 13, and is performed automatically or manually before the adsorption member 13 reaches its saturated adsorption amount. The damper 19 is operated to switch the air path, the desorption member 14 desorbs the malodorous components adsorbed on the adsorption member 13, and the pump 18 causes the adsorption member 13 to be reused by bubbling it into water through the bypass pipe 15 and dissolving it. The deodorizing effect can be maintained for a long period of time since the adsorption member 13 does not need to be replaced, which was necessary in the past. Furthermore, since the saturation adsorption amount of the adsorption member 13 can be set to a small value, the size of the adsorption member 13 can be reduced.

For example, when an oxidation catalyst is provided for decomposition treatment, it is necessary to heat the catalyst to 400"C or higher, which requires a heater and a heat insulating member. In this example, the malodorous components are dissolved by bubbling them into the water. Since the process is carried out by doing this, the process can be carried out at room temperature, and the structure can be simplified and costs can be reduced.

FIG. 2 shows another embodiment of the present invention, in which an anode 22 and a cathode 23 are disposed as an underwear member 14a via an adsorption member 13, and a high-pressure generator is used to apply a pulse arc to the adsorption member 13. It is composed of 24 parts. The other parts are the same as those in the embodiment shown in FIG. 1, so the same reference numerals are given and the explanation will be omitted.

With this configuration, when the high voltage generator 24 is energized, the anode 2
2. A pulse arc corresponding to the size of the adsorption member 13 is generated between the cathodes 23, and although the temperature of the adsorption member 13 as a whole is relatively low, it reaches a high temperature of tens of hundreds of degrees within the microstructural region. , organic substances and other adsorbed components undergo carbonization or thermal decomposition. At the same time, a small amount of moisture coexisting with the organic substance instantly turns into a superheated steam state, and a so-called water gas reaction occurs with the carbonized organic matter, resulting in partial gasification and removal. Such a reaction occurs one after another in a short period of time due to the pulsed arc, and progresses like a chain reaction.

When attaching and detaching by heating with a heater etc., heat conduction to the surroundings,
Due to heat dissipation, it takes a relatively long time to reach a desorption temperature of 300''C, but pulsed arc has the effect of completing desorption in a short time.

Effects of the Invention As detailed above, the present invention adsorbs malodorous components using an adsorption member, desorbs them at a predetermined time using a desorption member, and dissolves malodorous components by bubbling them into water using a pump through a bypass pipe. The following effects can be obtained.

(1) Since the adsorption member can be repeatedly regenerated and used, there is no need to replace the adsorption member, which was previously necessary, and highly efficient deodorizing effects can be maintained over a long period of time.

Furthermore, since the saturation adsorption amount of the adsorption member can be set to a small value, the adsorption member and the entire device can be downsized.

(2) It is possible to treat malodorous components at room temperature by bubbling them into water and dissolving them, which simplifies the structure and lowers costs compared to, for example, decomposition treatment using an oxidation catalyst. realizable.
