Abstract

PURPOSE:To perform passive and active deodorizing for a long time by exposing a solution of a deodorant based on a dialkylamino component and a sulfonate component or the gel like composition thereof to air. CONSTITUTION:A deodorizing device 11 is arranged between the suction grill 2 and heat exchanger 5 of an air conditioner 1 and constituted by receiving an aqueous solution 13 of a polybutadiene derivative in a rectangular parallelepiped container 12 opened at the upper part thereof and immersing a nonwoven fabric 14 in said aqueous solution in order to accelerate evaporation. The polybutadiene derivative is prepared by introducing a lower alkylamino group and a sulfonate group into polybutadiene low in a degree of polymerization based on 1,4-polybutadiene by substitution or addition reaction. When the aqueous solution of the polybutadiene derivative or the gel like composition thereof is used, said derivative is well diffused to air and the contact probability with a malodorous component is high and, therefore, deodorizing effect increases.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a deodorizer, for example, an air conditioner.

It is used to prevent unpleasant air conditioning caused by odors even during long-term operation by keeping it open to the Japanese air flow path.

(b) Technology from 6'E When operating an air conditioner, the room becomes airtight, causing problems such as food odors, cigarette odors, sweat, rotting odor from wall materials, etc. It adheres to the heat exchanger of the conditioner and causes odor when blowing air or heating.

Therefore, as a deodorizing method, it is possible to deal with this by attaching activated carbon or the like to the filter of the air conditioner.

For example, filter material sprinkled with powdered activated carbon,
It has also been proposed to use a filter made of activated carbon fibers, but in order to obtain a sufficient deodorizing effect, the thickness of the filter material must be increased, resulting in increased pressure loss, increased fan static pressure, and noise. There are many negative effects such as an increase in the amount of carbon, and the low pressure drop type has a small amount of activated carbon and is ineffective, so it has not been commercialized.

Furthermore, whether it is made into powder or fiber form, it is inevitable that the product will scatter, which can be harmful to health, and since it is an adsorption type, it also has the disadvantage that its deodorizing effect decreases over time. . In the case of activated carbon, the odor comes into contact with the activated carbon and is absorbed into the small pores.The deodorizing state is "passive" in that it waits for the odor to enter, and the odor that does not enter the air can be removed. difficult.

On the other hand, some air cleaners have recently used fragrances, but they only serve as masking agents and have no deodorizing effect.

(c) Problems to be Solved by the Invention The present invention has been made in view of the various problems mentioned above. Effective and even “passive”
A deodorizer that “chases” “active” odors in contrast to active deodorization.
That is, an object of the present invention is to provide a deodorizer that is capable of removing not only odors in the air but also attached odors.

(d) Means for Solving the Problems The deodorizer of the present invention uses a solution of a deodorant containing a dialkylamino group and a sulfonate group or a gel-like material thereof so as to diffuse the deodorizing component into the air. It is designed to be exposed to the air.

This deodorant includes a polybutadiene derivative obtained by introducing a di-lower alkylamino group and a sulfonate group into a low polymerization degree polybutadiene.

This polybutadiene derivative is obtained by substituting or additionally introducing a di-lower alkylamino group and a sulfophole l-group into a low polymerization degree polybutadiene mainly consisting of 1.4-bolybutadiene.

Among them, preferable ones include: (In the formula, R2 and R2 are each independently a lower alkyl group having 4 or less carbon atoms, n is an integer of 11 to 13, and
indicates an alkali metal. ) 1,4-polybutadiene derivatives represented by:

Such polybutadiene derivatives diffuse well into the air when made into an aqueous solution or when a gel-like substance of the aqueous solution is used, and even though the concentration is dilute, the probability of contact with odor components is high and it is effective for deodorization. The effect increases.

(e) Effect: According to the present invention, sulfur-based malodors such as nitrite, acid gas, hydrogen sulfide, and mercaptan disappear by reacting with amine groups, and rotten meat odors such as ammonia, nitrogen dioxide, and peptone are eliminated. Nitrogen-based bad odors disappear by reactive bonding with sulfonate groups, and halogens and aldehydes disappear by addition bonding to double bonds, and the Pi fruit deodorizing effect (for IE) is developed.

(f) Example Hereinafter, an example in which the deodorizer of the present invention is installed in an air conditioner will be described.

In Figure 1, the air conditioner (1) has a suction grill (2
), discharge port (3), 4 wind direction changing blades (4), heat exchanger (
5), cross flow fan (6), fan casing (
7), an air filter (8), an outer box (9), and a locking tool (10). Said suction grill (2)
A deodorizer (11) is disposed between the heat exchanger (5) and the heat exchanger (5). The deodorizer (11) has an aqueous solution (13) of a polybutadiene derivative placed in a rectangular parallelepiped container (12) with an opening at the top, and a nonwoven fabric (14) is immersed therein to promote evaporation. Further, the container (12) is attached to a support frame (15), and contains water-soluble i? A part of the suction grille (2) is made removable so that the IQ of t(13) can be performed more easily. In the figure, (16) is the indoor wall, (17)
(18) is a screw (17) on the interior wall (1)
One of the wall-hanging plates fixed by is a dew pan placed below the heat exchanger (5).

(g) Effects of the Invention The deodorizer according to the present invention exhibits excellent deodorizing effects for a long time without problems such as pressure loss and separation unlike conventionally used activated carbon filters, and is also an active deodorizer. Smell is also something that does something, and is useful.
