An air outlet 30 provided on the other side of the humidifier body; And

A moisture and moisture retaining material receiving portion 42 divided into a second layer, an air passage portion 47 divided into a first layer on the lower surface of the second layer, and the first and second layers, Includes; a humidifier body 40 including a partition plate 45 in which a plurality of air movement ports are formed,

The water-retaining material includes mixed water-swellable polymer particles and porous particles, and the water-retaining material retains moisture by water-swelling of the water-swellable polymer 43 and the porous portion of the porous particles 44;

The air inlet 20 communicates with the first layer so that air is introduced into the first layer, and the air introduced into the first layer is transferred to the first layer through a plurality of air moving ports formed in the partition plate 45. It is characterized in that it is ejected into the air outflow part 30 communicated with the second layer moisture and moisture retaining material receiving part 42 after moving through the water retaining material 43 and 44 of the second layer.

In one embodiment of the present invention, the water retaining material (43, 44) may include the water-swellable polymer particles (43) and the porous particles (44) in a volume ratio of 3:7 to 7:3, more preferably May be included in a volume ratio of 4:6 to 6:4. When the volume ratio of the water-swellable polymer particles is less than 3, the water retention is likely to be insufficient, and when the volume ratio of the porous particles is less than 3, the air flow path may be blocked after the water-swellable polymer is swelled.

In the present invention, the porous particles 44 can retain moisture due to the porous pores, and even when the water-swellable polymer lowers the air permeability due to swelling, the air passage is secured so that the humidifying function of the humidifier is operated.

In one embodiment of the present invention, the average particle diameter of the water-swellable polymer particles 43 may be 0.1 μm to 3 mm, and the average particle diameter 44 of the porous particles may be 0.25 μm to 7.5 mm.

In the above, when the particle diameter of the porous particles 44 is less than 2.5 times, when the water-swellable polymer is swollen, the air permeability may be significantly lowered, and when it exceeds 10 times, the moisture retention of the moisture retaining material may be lowered.

In one embodiment of the present invention, as the water-swellable polymer particles, natural products such as cellulose-based (CMC-based), starch-derived systems, and synthetic polymers such as polyacrylic acid-based, polyethylene oxide-based, polyether-based, and PVA-based are used. I can. For example, in the preparation of polyacrylic acid-based polymer particles, first, methyl methacrylate and vinyl acetate are copolymerized, and then hydrolyzed to obtain a super absorbent polymer of polyacrylic acid-polyvinyl alcohol converted to a carboxyl group or hydroxyl group. (Han Yang-gyu et al., “Water-swellable polymer”, Polymer (Korea) Vol. 13, No. 1, the water-swellable polymer described in January 1989 can be used).

The water-swellable polymer particles are not particularly limited, and commercially available ones may be purchased and used.

The porous particles include zeolite particles, mesosilica particles, metal organic structures (MOFs), porous polymer composites (MOPs), porous alumina oxide (AAO), activated carbon particles, porous carbon and potassium porous particles such as carbon molecular sieves, and the like. , Porous polymer particles may also be used. The porous particles may be purchased and used commercially.

In one embodiment of the present invention, the water retaining material (43, 44), as shown in Figure 3, after spraying the binder on the outer surface of the individual porous particles 44, water-swellable polymer particles 42 By mixing with, a mixture in which water-swellable polymer particles are coated on the outer surface of the porous particles may be included. When using a mixture in which the porous particles 44 are coated with the water-swellable polymer particles 42 as described above, due to the difference in size and density of the porous particles 44 and the water-swellable polymer particles 42, The problem of not being uniformly mixed with each particle can be prevented. That is, in the moisture-retaining material, the porous particles 44 and the water-swellable polymer particles 42 must be mixed in a uniform distribution to secure the air flow path. However, due to the difference in size and density between the dissimilar particles, It is not easy, and even if released in a uniformly mixed state, each particle is ubiquitous due to shaking during transport or use, causing a problem that it is difficult to properly secure an air flow path. Therefore, the moisture-retaining material of the present invention can solve the above problems by including a mixture in which the porous particles 44 are coated with the water-swellable polymer particles 42.

In the above, the binder may preferably include a copolymer represented by the following Formula 1:

[Formula 1]

In the above formula

a and b are mole fractions, a is 0.3 to 0.7, b is 0.3 to 0.7, and a+b=1.

In the present invention, since the moisture retaining material performs a function of retaining moisture, a binder having a strong binding force even in water must be used, and in particular, must be harmless to the human body. The copolymer represented by Formula 1 is a natural component that is harmless to the human body, and contains a catechol monomer having a characteristic of forming strong adhesion to organic or inorganic substances, and as a natural component, strong adhesion to organic and inorganic substances. A poly(2-dimethylamino)ethyl methacrylate) methyl chloride quaternary salt (Poly(2-dimethylamino)ethyl methacrylate) methyl chloride quaternary salt monomer is included.

Therefore, when used for bonding of the moisture retaining material as described above, it is possible to effectively maintain the bonding of the porous particles 44 and the water-swellable polymer particles 42 even in water.

The copolymer may be a random copolymer, and one having a weight average molecular weight of 50,000 to 2,000,000 may be used, more preferably 80,000 to 200,000.

The humidifier for mounting a car air outlet of the present invention may further include a moisture supply port 50 as shown in FIG. 3. That is, when moisture is insufficient through humidification, the humidifier of the present invention can be reused repeatedly by supplying moisture through the moisture supply port 50.

In addition, the humidifier for mounting an automobile air vent of the present invention may be manufactured and supplied in a state in which water is received or in a state in which water is not received. In the case of supplying water in a state of being contained, it is required to seal the humidifier so that moisture does not evaporate spontaneously.

The humidifier for mounting a vehicle air outlet of the present invention, as shown in FIG. 3, may be mounted on the air outlet 60 of the vehicle, and specifically, a fixing member 10 is attached to the direction control pin 62 of the air outlet 60. It can be fixed and mounted. The shape of the fixing member 10 is not particularly limited if it can perform the functions described above, and a technique known in the art may be employed.

Hereinafter, the present invention will be described in more detail through examples. However, the following examples are for explaining the present invention more specifically, and the scope of the present invention is not limited by the following examples. The following examples can be appropriately modified and changed by those skilled in the art within the scope of the present invention.

Preparation Example 1: Synthesis of a polymer compound of Formula 1

Poly(2-dimethylamino)ethyl methacrylate) methyl chloride quaternary salt monomer (manufactured by Sigma Aldrich) and dopamine methacrylamide in 1:1 It was added at a molar ratio, and 0.5 parts by weight of normal mercaptan was mixed with 100 parts by weight of the total monomer to make it uniform. A small amount of disodium hydrogen phosphate was dissolved and stirred in 130 parts by weight of ion-exchanged water in a stainless steel high pressure reactor equipped with a stirrer, and the inside of the reactor was filled with an inert gas such as nitrogen and heated. The reaction was terminated by polymerization for 2 hours at 65°C and 1.5 hours at 100°C. After the reaction was terminated, washing, dehydration, and drying were performed to obtain a polymer compound of Formula 1 having a weight average molecular weight of 113,000.

[Formula 1]

In the above formula,

a is 0.5 and b is 0.5 (a and b are molar ratios, a+b=1)

Preparation Example 2: Preparation of water retaining material

Shown in Figure 3 As described above, a mixture in which water-swellable polymer particles (polyacrylic acid-polyvinyl alcohol superabsorbent resin) were coated on the outer surface of the porous particles (zeolite) was prepared by the following process. In this case, the average particle diameter of the porous particles (3 mm) was used to be 4 to 5 times the average particle diameter of the water-swellable polymer particles (0.7 mm).

First, while sporadically dropping the porous particles, the binder prepared in Preparation Example 1 is sprayed to coat the binder on the surface of the porous particles. Thereafter, the porous particles coated with the binder are dropped into a container containing water-swellable polymer particles, and at this time, the water-swellable polymer particles included in the container are stirred at a constant speed while being bound to the outer surface of the falling porous particles. Thereafter, the porous particles coated with the water-swellable polymer particles were dried.

Example 1: Manufacture of a humidifier for mounting an automobile air vent

As shown in FIG. 3, the moisture and moisture retaining material receiving portion 42 is filled with the moisture retaining material prepared in Preparation Example 2, and water is supplied through the moisture supply port 50 so that the moisture is contained in the water-swellable polymer. A humidifier for mounting an automobile air outlet was prepared by being retained in the pores of the swelling and porous particles.

Comparative Example 1: Manufacture of a humidifier for mounting an automobile air outlet

In the same manner as in Example 1, a humidifier for mounting an automobile ventilator was manufactured in the same manner as in Example 1, except that a moisture retaining material made of only water-swellable polymer was used instead of the moisture retaining material prepared in Preparation Example 2.

Comparative Example 2: Manufacture of a humidifier for mounting an automobile air vent

In the same manner as in Example 1, a humidifier for mounting an automobile air outlet was manufactured in the same manner as in Example 1, except that the porous polymer and the water-swellable polymer were simply mixed in a volume ratio of 5:5 instead of the moisture retaining material prepared in Preparation Example 2.

Test Example 1: Performance evaluation of a humidifier for mounting an automobile air outlet

The humidifiers of Example 1 and Comparative Examples 1 and 2 were mounted on an automobile blower to evaluate their performance. The results are shown in Table 1 below.

<Evaluation criteria>

◎: Excellent humidification performance

○: Normal humidification performance

△: Insufficient humidification performance

×: No humidification

Example 1 humidifier
Humidification performance Comparative Example 1 Humidifier
Humidification performance Comparative Example 2 Humidifier
Humidification performance After adding water, use once ◎ × ○ After water replenishment, use twice ◎ × △ After water refill, use 3 times ◎ × △ After water refill, use 5 times ◎ × △

As shown in Table 1, the humidifier of Example 1 of the present invention exhibited very excellent humidification performance.

On the other hand, the humidifier of Comparative Example 1 did not exhibit humidification performance from the beginning. It was confirmed that the cause was that the water retaining material was composed only of water-swellable polymer particles, and the air passage was not secured when the polymer was swelled and the air outlet was closed.

In the case of the humidifier of Comparative Example 2, initially exhibited normal humidification performance, but showed insufficient humidification ability from the second round. After the experiment was completed, the humidifier was disassembled and checked. As a result, it was confirmed that the porous particles and water-swellable polymer particles contained as a moisture retaining material were not uniformly mixed, but existed in an unevenly distributed state. In other words, it seems that the humidification capacity was deteriorated because the air flow path was not properly secured according to this ubiquitous state.

Test Example 2: Performance evaluation of the moisture retaining material prepared in Preparation Example 1

An experiment was conducted in which the porous particles coated with the water-swellable polymer particles prepared in Preparation Example 2 were immersed in water for 1 hour, taken out, and dried 30 times. As a control, a moisture retaining material prepared in the same manner as in Preparation Example 2 was used, except that a polyvinyl alcohol binder was used.

As a result of the above experiment, in the porous particles coated with the water-swellable polymer particles prepared in Preparation Example 2, separation of the porous particles and the water-swellable polymer particles was not observed at all until the completion of the 30 experiments.

On the other hand, in the case of the control group using a polyvinyl alcohol binder, separation between the porous particles and the water-swellable polymer particles began after 10 times, and it was confirmed that about 50% of the separation between particles occurred when the 30 experiments were completed.

Therefore, from the above experiment, it was confirmed that the moisture retaining material of Preparation Example 2 using the binder prepared in Preparation Example 1 has much better durability than the moisture retaining material using a polyvinyl alcohol binder.
