DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device for directly collecting odors in a toilet bowl and deodorizing the same.

[0002]

2. Description of the Related Art As a well-known deodorizing device, a suction port 5 is provided at the tip of a gap 4 between a toilet bowl 1 and a toilet seat 3 having a toilet lid 2, as shown in FIG. A suction duct 6 having a deodorant made of activated carbon or the like and a deodorizer 8 having a blower for suction or the like, or installed in a toilet space 9 to remove the odor in the toilet 7 from the toilet 7 Some odors diffused into the space 9 are decomposed and deodorized with a catalyst such as a platinum catalyst. Arrows in the figure indicate the flow of the odor. In recent years, although not shown in the figure, the air is sucked from the rear of the toilet 1 and discharged into the toilet space 9 by a deodorizing circuit including a deodorant and a blower incorporated in the toilet seat-integrated warm water flush toilet seat.
In each of the above three examples, the odor is suctioned and released into the toilet space 9 after the treatment.
31 is provided with a suction port and an outlet at a position facing the inside of the toilet of the deodorizer main body having an ozone generator, generates ozone from the outlet to deodorize the toilet, and circulates the odor sucked in the toilet with a blower. ing.

[0003]

However, in the case of the conventional deodorizer 8 having only the suction port 5, since the main body of the deodorizer 8 and the suction duct 6 are integrated, suction is performed only from a part of the gap 4. Not possible, and 0.1 from the thermal sensation of the human body
Only a part of the odor is collected because it can be sucked only with an air flow of about m ³ / min or less. Further, when the odor diffuses into the toilet space 9 once, the deodorization is started after the toilet user perceives the smell, so that the toilet user hardly feels the deodorizing effect like the ventilation fan. On the other hand, in the case of a collecting means having a suction port and an air outlet and circulating, since a sufficient blowing flow rate cannot be obtained in terms of thermal sensation, the effect of circulating and collecting is not sufficiently drawn out, and ozone is also generated. The effect on the human body by blowing into the toilet may be considered. Further, none of the above deodorizers has a problem that a sufficiently satisfactory deodorizing effect has been obtained on basic toilet odor components such as ammonia and sulfur-based toilet odor components such as hydrogen sulfide.

[0004]

According to the present invention, there is provided a collecting block comprising a suction unit having an opening inside a toilet, and a main body connected to the collecting block via connecting means. A blower, an adsorbent, a desorption heater, and a decomposition catalyst having a heating means are disposed in an air path, and the blower, the desorption heater, the decomposition catalyst, and the operation of the decomposition catalyst are controlled. A deodorizing block comprising a circuit, wherein the deodorizing block is disposed in the order of a decomposition catalyst, an adsorbent, a desorption heater, and a blower.

According to the above invention, the adsorbent adsorbs sulfides such as hydrogen sulfide and methyl mercaptan and basic gases such as ammonia and trimethylamine, and continuously adsorbs odors without letting them out of the toilet. Because it can be supplied to the material, both collection and deodorization efficiency can be improved,
The performance for final toilet deodorization can be greatly improved. The adsorbent is sandwiched between the decomposition catalyst and the heater for desorption, so that the regeneration time can be shortened.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a collecting block comprising a suction unit having an opening in a toilet having a toilet seat installed in a toilet space, and connected to the collecting block via a connecting means. A blower, an adsorbent, a desorption heater and a decomposition catalyst having a heating means are disposed in the main body air passage, and the operation of the blower, the desorption heater and the decomposition catalyst is controlled, and the human body detection means is controlled. And a deodorizing block comprising a control circuit having the deodorizing block, wherein the deodorizing block is disposed in the order of a decomposition catalyst, an adsorbent, a desorption heater, and a blower. When the user enters the toilet space, the human body detection means senses, the operation of the blower is started, and when the user sits on the toilet seat, deodorization is already performed, so the odor is processed before spreading out of the toilet .
In this case, the odor generated in the toilet is generated because the space inside the toilet is blocked by the buttocks of the user except for a part of the front and the gap between the toilet and the toilet seat during the toilet. It is sucked in from a suction part provided near the location.

As a result, it is possible to realize deodorization with almost no odor even if the user completes the toilet and stands up from the toilet seat.

[0008] The regeneration of the adsorbent is carried out by heating the adsorption sandwiched between the desorption heater and the decomposition catalyst. Since this adsorbent is heated from both sides by the desorption heater and the heating source for the decomposition catalyst, it is efficient. The regeneration of the adsorbent that can be regenerated is performed by heating the adsorption sandwiched between the desorption heater and the decomposition catalyst. However, since this adsorbent is heated from both sides by the desorption heater and the heating source for the decomposition catalyst, it is efficient. Can be played back.

The adsorbent is a mixture of an adsorbent for a sulfur-based compound, an adsorbent for a basic compound, and an adsorbent for a hydrocarbon, so that one can adsorb toilet odor and a plurality of adsorbents can be used. As compared with, the heat capacity is smaller and the desorption energy is smaller.

Since the adsorbent has an upstream side as an adsorbent for a sulfur compound and an downstream side as an adsorbent for a basic compound and an adsorbent for hydrocarbons, the respective adsorbents do not interfere with toilet odor. It can be collected efficiently.

A heat insulating material having a plurality of vents is provided in the deodorizing block on the upstream side of the decomposition catalyst. Therefore, even if the power supplied to the desorption heater and the decomposition catalyst becomes excessive and the air temperature at the decomposition catalyst outlet rises, the heat insulating material recovers heat, so that the heat insulating material outlet temperature can sufficiently withstand the resin material. Temperature.

The heat insulating material has a plurality of vents made of an inorganic material and can be attached to and detached from the deodorizing block, so that it can have a function as a renewable filter.

The gas collected in the suction section flows out of the outlet through the decomposition catalyst, the adsorbent, the desorption heater and the blower. Therefore, the air containing the odor component flowing through the adsorbent has a uniform flow, and the contained odor component is adsorbed with high efficiency.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a view showing the configuration of a toilet deodorizing apparatus according to Embodiment 1 of the present invention. The toilet deodorizing device is mainly composed of two blocks. One is a collection block 10, which is located at a location opened in the toilet 11.
Shows a state in which the toilet seat 12 is opened, and a suction section 13 is provided substantially opposite to the rear. On the other hand, a deodorizing block 14, which is another block, includes a heat insulating material 18 in which inorganic fibers are formed in a corrugated shape in a main body air passage 17 having both ends of an inlet 15 and an outlet 16 and a self-heating based on platinum / palladium. Type decomposition catalyst 19, an adsorbent for chemically adsorbing sulfides such as hydrogen sulfide and methyl mercaptan, and an adsorbent for adsorbing basic gases such as ammonia and trimethylamine.
An adsorbent 20 carrying an adsorbent for adsorbing other gases, a demounting heater 21 using a Milacron heater, and a blower 22 are sequentially arranged. Adsorbent 20
Has an adsorbent for sulfur-based compounds on the upstream side and an adsorbent for basic compounds and an adsorbent for hydrocarbons on the downstream side. The heat insulating material 18 can be detached from the deodorizing block 14.
The self-heating type decomposition catalyst 19 is provided on the upstream side of the adsorbent 20, and the adsorbent 20 is sandwiched between the heater 21 and the desorption heater 21. The suction port 15 is connected and connected to the suction section 13 of the collection block 10 by a flexible duct 23. Further, the deodorizing block 14 has a room temperature detecting means 24 such as a thermistor for detecting the room temperature in the toilet space in which the deodorizing device is installed, and an infrared sensor, an ultrasonic sensor, or the like for detecting that the toilet user has entered the toilet space. A human body detecting means 25 comprising a seat switch and the like is attached, and a control circuit 2 for operating them and controlling the operation of the blower 22, the detachable heater 21, and the self-heating type decomposition catalyst 19.
6. Further, the gas collected by the suction unit 13 is
Heat insulating material 18, decomposition catalyst 19, adsorbent 20, desorption heater 2
1. The blower 22 is provided so as to flow out of the outlet through the blower 22.

Next, the operation and operation will be described. When the user enters the toilet space, the room temperature signal is also sent from the room temperature detecting unit 24 to the control circuit 26 at the same time as the room signal from the human body detecting unit 26, and the blower 22 which is preset by the control circuit 26 from the room temperature detecting signal Is started. Therefore, after the odor is collected by the suction unit 13,
The adsorbent 20 enters through the duct 23. Here, sulfur-based compounds and basic gases contained in the air are adsorbed. The odorless air is released from the outlet to the toilet space.

When this adsorption operation is repeated several times, the control circuit 26 energizes the desorption heater 21 to desorb the odor component to the adsorbent 20 and simultaneously energizes the self-heating type decomposition catalyst 19 composed of an oxidation catalyst. The odorous component, which is kept at a high temperature and desorbed, passes through to decompose into carbon dioxide and water. Even if the regeneration is completed and the energization of the heater 21 is stopped, the energization of the self-heating type decomposition catalyst 19 continues for a while. The deodorizing block 14 that can regenerate the adsorbent 20 can be used semi-permanently without being influenced by the adsorption capacity. The heat insulating material 18 functions to recover waste heat when the adsorbent 20 is regenerated. For this reason, the air temperature at the outlet of the heat insulating material does not become high. The adsorbent 20 is a self-heating type decomposition catalyst 1
9 is sandwiched between the heater 9 and the desorption heater 21, so that even if the shape is long in the vertical direction, the upper and lower temperatures are hardly applied.

[0018]

As described above, according to the present invention, an adsorbent is formed by mixing adsorbents having different adsorption characteristics, and a means for regenerating the adsorption is provided. It can be effectively removed over a long period. Since the adsorbent that needs to be regenerated is sandwiched between the desorption heaters, the temperature of the adsorbent can be raised efficiently, and the regeneration time can be shortened. At this time, since the heat insulating material stores waste heat, the temperature of the air exhausted to the toilet space does not rise so much.
