[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for forming a comfortable living space.

[0002]

2. Description of the Related Art Recently, in order to form a comfortable living space, a prefilter that catches large dust and dust, an electrostatic filter that catches fine particles such as cigarette smoke and house dust, and a strong odor eliminator Various air purifiers have been developed by combining deodorant filters. In addition, various humidifiers are used in order to obtain an appropriate humidity during drying.

Conventionally, for example, a humidifier using ultrasonic waves or a method of heating water by a heating means such as a heater to evaporate it to create a humidified state has been conventionally used. On the other hand, in order to form a comfortable living space, various deodorants and deodorizing means are used to remove a bad odor, and various fragrances and deodorants are used to eliminate the bad odor and to fill the space with a pleasant scent. Fragrance means are used.

[0004]

However, even the conventional air purifier cannot be said to be a complete air purifier because it does not have the humidifying function of air and the aroma function after deodorizing treatment. In a humidifier using a conventional heating means, water vapor is blown out vigorously, so that the room is excessively humid (over-humidified state).

The ultrasonic method has a problem that furniture may become whitish. In order to create a comfortable living space, the device used when adjusting the humidity of the room is, for example, small, highly safe without using a heater, etc., and economical with reduced electricity consumption. It is required to have characteristics such as being a physical one. In addition, as a general consumer's thought these days, it is not possible to be satisfied with only one function or characteristic, and there is a demand for one to which various functions are added.

The object of the present invention is to solve the above-mentioned problems in the humidifier and to satisfy the required characteristics of the humidifier used for forming a comfortable living space, and to form a more comfortable living space. It is to provide an air conditioner with the necessary air purification function, aroma function, deodorizing function, and humidifying function.

In the air conditioner of the present invention, water is vaporized in accordance with the dryness of the gas to be supplied and an appropriate humidity is given without using a heating means. The humidity of the gas is automatically reduced, which is different from the type of leaving it humidified when the switch is turned on. In addition, the supplied gas is purified by the filter part, so it becomes a very clean gas, and after removing the bad odor by deodorizing treatment, the atmosphere of the room can be changed by selecting the fragrance according to your taste and the atmosphere at that time. Can be changed.

FIG. 1 is a schematic view showing the structure of the main part of the air conditioner of the present invention. This air conditioner includes a humidifying section A, an aroma generating section B, a filter section C, a deodorizing section D, and a gas supply section E.

In the water tank 2 of the humidifying section A, a large number of microporous hollow fibers 1 which are focused and fixed by a fixing member 4 made of an adhesive or the like while keeping both ends open are stored. One open end of the microporous hollow fiber 1 is open toward the void 5, and the other open end is open to the atmosphere. The water filled in the water tank 2 and the microporous hollow A gas passage having a portion partitioned by the membrane wall of the yarn is formed.

The water filled in the water storage tank 2 is kept airtight by the water storage tank 2, the membrane wall of the microporous hollow fiber 1 and the fixing member 4. The water tank 2 is provided with a water injection port 3 having an openable and closable lid for injecting water into the water storage tank 2, and after the water injection, the lid of the injection port 3 is closed. As the microporous hollow fiber 1, one having a property of allowing water vapor to pass though it normally does not allow water to pass is used. Among them, hydrophobic microporous hollow fibers can be preferably used because of their high water vapor transmission rate.

Examples of the hydrophobic microporous hollow fibers include polyolefin hollow fibers such as polyethylene, polypropylene and poly-4-methylpentene-1, and fluoropolymer hollow fibers such as polyvinylidene fluoride and polytetrafluoroethylene. There is no particular limitation as long as it has a property of having a microporous structure.

The membrane morphology and membrane performance of the microporous hollow fiber may be appropriately selected in accordance with the desired characteristics of the device depending on the use of the device incorporating it and the size of the space for humidity control. ..

The inner diameter of the microporous hollow fiber is, for example,
It is preferably 20 μm or more, which does not give a large resistance to gas permeation in the hollow portion. Further, considering the miniaturization of the device, it is preferably about 2000 μm or less. The pore size in the membrane wall of the microporous hollow fiber 1 can be appropriately selected so that water does not enter the gas passage side due to the water pressure in the water storage tank.

The porosity of the porosity is 30% or more in order to prevent a large resistance to water vapor permeation.
Considering strength, 90% or less is preferable. Furthermore, the porosity is 30 to 90%, and the surface area is 20 to 80 m ² / g.
With a very large open space, the contact area between water and gas through the hollow fiber membrane wall is large, and efficient generation of water vapor enables efficient acquisition of a saturated state of water vapor in the hollow part of the hollow fiber. To more preferable.

In order to prevent the membrane pressure of the microporous hollow fiber 1 from becoming a great resistance to the permeation of water vapor, it is 20
It is preferably 0 μm or less and 5 μm or more in consideration of strength.

In the fragrance storage tank 7 of the fragrance generating section B, a large number of multi-layer composite hollow fiber membranes 6 which are focused and fixed by fixing members 9 made of an adhesive or the like while keeping both ends open.
Is stored. One open end of the multilayer composite hollow fiber membrane 6 is opened toward the void 5, and the other open end is the void 1.
A gas passage having an opening toward 0 and having a portion partitioned by the fragrance and the membrane wall of the multilayer composite hollow fiber filled in the fragrance storage tank 7 is formed.

The fragrance contained in the fragrance storage tank 7 is
The airtight state is maintained by the fragrance storage tank 7, the membrane wall of the multilayer composite hollow fiber membrane 6 and the fixing member 9.

The fragrance storage tank 7 is provided with an inlet 8 having an openable / closable lid for injecting the fragrance into the inside, and the lid of the inlet 8 is closed after the injection.

Although it is possible to use a microporous hollow fiber as the hollow fiber membrane used in the aroma generating part, there is a problem that if a liquid aromatic agent containing a substance containing a vaporizable component is used, the liquid aromatic substance is easily removed. Become. In addition, since the microporous material is porous, the vapor velocity of the vaporizable component is high, and there is a problem that stable sustained release performance cannot be maintained for a long period of time.

In order to solve such a problem, a new hollow fiber membrane is needed. Therefore, the multilayer composite hollow fiber membrane 6 used in the aroma generating part of the present invention is composed of a homogeneous membrane (A) and a porous membrane (B) having a reinforcing function, as shown in the schematic diagram of FIG. It has a three-layer structure. The homogeneous membrane (A) and the porous membrane (B) are alternately laminated,
The inner and outer surfaces of the multilayer composite hollow fiber membrane are porous membranes (B)
Which has a sandwich structure in which the homogeneous membrane (A) is sandwiched between the porous membranes (B). In this multilayer composite hollow fiber membrane, one layer is basically sufficient as the homogeneous membrane (A), but it may have a multilayer structure of two or more layers.

The film thickness of the homogeneous film (A) is 10 μm or less. On the other hand, the thickness of both porous membranes (B) sandwiching the homogeneous membrane (A) is not particularly limited as long as it has a thickness capable of reinforcing the function of the multi-layer composite hollow fiber membrane, and both the inner and outer layers are porous. The film thicknesses of the film (B) may be the same or different.

The polymer material constituting the homogeneous membrane (A) is not limited to the silicone rubber type polymer having excellent gas permeability, but may be a silicone rubber type polymer such as polydimethylsiloxane, a copolymer of silicon and polycarbonate, or poly. -4-Polymethylpentene-1, polyolefin polymers such as linear low-density polyethylene, fluorine-containing polymers such as perfluoroalkyl polymers, cellulose polymers such as ethylcellulose, polyphenylene oxide, poly-4-vinylpyridine and these polymer materials Various polymers such as copolymers or blends of

In order to effectively and sustainably release the vaporizable component for a long time, it is necessary to set the thickness of the homogeneous film to 10 μm or less. When the gas permeability is used as an index, it is preferable that the oxygen gas permeation rate is 1 × 10 ⁻⁶ [cm ³ (STP) / cm ² · sec · cmHg] or more.

As the polymer material constituting the porous membrane (B), polyolefin polymers such as polyethylene, polypropylene, poly-3-methylbutene-1, poly-4-methylpentene-1, polyvinylidene fluoride and polytetrafluoro. Fluorine-based polymers such as ethylene and hydrophobic polymers such as polystyrene and polyetheretherketone can be used.

A polymer material constituting the homogeneous film (A),
The combination with the polymer material forming the porous membrane (B) is not particularly limited, and different polymers may be the same polymer as a matter of course. Since the homogeneous membrane (A) has a sandwich structure in which it is physically sandwiched between the porous membranes (B), even if the adhesiveness between the two membranes is poor, no practical adverse effect occurs.

Since the porous membrane (B) mainly functions to reinforce the homogeneous membrane (A), it has pores to the extent that the gas permeability of the multilayer composite hollow fiber membrane as a whole is not restricted. If so, the size of the pores and the like are not particularly limited.

In such a multilayer composite hollow fiber membrane, for example, a polymer forming the homogeneous membrane (A) and a polymer forming the porous membrane (B) are alternately and alternately used by using a multi-cylindrical spinning nozzle. Under the condition that the polymer forming the homogeneous membrane (A) is arranged so as to be sandwiched and melt-spun, and then only the porous membrane (B) is made porous without making the homogeneous membrane (A) porous. It is manufactured by a stretching method.

A large number of hollow fibers 11 are accommodated in a loop shape inside the outer cylinder 12 of the filter section C. Both ends of each hollow fiber are kept in an open state and are converged and fixed to a fixing member 13 made of an adhesive or the like. Each of the open ends is opened toward the void 10.

Therefore, the filtered gas discharged into the void 10 and the gas to be filtered supplied to the region side of the outer cylinder 12 where the outer wall surface of the hollow fiber 11 is in contact with the hollow fiber 11 and the fixing member 13. It will be airtightly divided by. Moreover, the region where the outer wall surface of the hollow fiber 11 contacts is in contact with the deodorizing portion.

The hollow fiber 11 used in the filter portion C can be used without any limitation as long as it has a function of filtering solid matters and impurities in the gas, and if it is a material having a low gas permeation resistance, it is hydrophilic. Either a material or a hydrophobic material may be used.

Although a hollow fiber is used for the filter portion C in the apparatus illustrated in FIG. 1, the present invention is not limited to this. For example, in addition to the hollow fiber, various forms such as a flat film can be used as the form of the filter for gas filtration. In addition to the porous membrane, non-woven fabrics, metal filters, and other various materials can be used.

In the outer cylinder 15 of the deodorizing section D, a deodorizing filter for strongly deodorizing unpleasant odors is arranged. As a material used for deodorizing a gas, a generally used material may be used, for example, activated carbon particles or fibrous activated carbon for absorbing an unpleasant odor may be used. The deodorizing part D
It is preferable to use a porous body as a partition wall between the filter section C and the filter section C so as not to resist the flow of gas.

The gas supply part E supplies the gas through the deodorizing part D and the filter part C into the hollow part of the multi-layer composite hollow fiber 6 of the aroma generating part B which adds the fragrance of the fragrance to the gas and further humidifies the gas. It is provided in order to supply to the hollow part of the microporous hollow fiber 1 of the humidifying part A to be released and to release the humidified aroma gas generated there into the atmosphere. For example, an air compressor, an air pump, a fan, etc. are used. Can be configured.

Next, the operation of generating aromatic humidified air using the apparatus of FIG. 1 will be described. First, the water is filled from the water inlet 3 into the water storage tank 2, and the lid of the water inlet 3 is closed.

Next, the fragrance according to one's taste and the atmosphere of the place is filled into the fragrance storage tank 7 through the inlet 8, and the lid of the inlet 8 is closed. Next, the air pump 16 used in the gas supply unit E is operated, and the deodorization unit D is operated at an appropriate gas pressure.
A gas such as air is supplied to the activated carbon layer inside.

The unpleasant odor of the gas supplied thereto is deodorized by the activated carbon layer, and the deodorized gas is supplied to the region where the outer wall surface of the hollow fiber 11 of the filter portion C contacts.

The gas supplied there flows from the outside of the hollow fiber 11 to the hollow portion through the membrane wall, and at that time, solid matters and impurities in the gas are filtered by the hollow fiber. The gas purified in the filter part C is supplied to the gas passage including the hollow part region of the multilayer composite hollow fiber 6 of the aroma generating part B through the void 10.

The gas supplied to the hollow area of the multilayer composite hollow fiber 6 is generated from the fragrance agent filled in the fragrance storage tank 7, passes through the membrane wall of the multilayer composite hollow fiber 6 and enters the hollow area. The fragrance that has reached is released to the void 5 as an aromatic gas.

The gas aromatized in the aroma generating part B is supplied to the gas passage including the hollow part region of the microporous hollow fiber 1 of the humidifying part A through the void 5.

The gas supplied to the hollow area of the microporous hollow fiber 1 is generated from the water filled in the water storage tank 2, passes through the membrane wall of the microporous hollow fiber 1 and enters the hollow area. It contains the reached water vapor and is released from the atmosphere as a humidified body.

In the apparatus of the present invention, it is possible to generate a clean gas to which appropriate humidification and aroma are added.
The pressure of the gas supplied from the gas supply unit E can be selected according to the desired humidity, fragrance, etc. of the gas released into the atmosphere.

In the example described above, each component is connected in the gas flow direction in the order of the gas supply part E, the deodorizing part D, the filter part C, the aroma generating part B and the humidifying part A. The positions where C, the fragrance generating portion B, and the humidifying portion A are provided are not limited to these.

For example, in the gas flow direction, the filter section C may be followed by the humidifying section A and the aroma generating section B, or the deodorizing section D may be followed by the aroma generating section B, the filter section C and the humidifying section. You may arrange in order of the part A. Further, depending on the case, the humidifying part A, the aroma generating part B, the filter part C
Multiple may be provided.

When the humidifying section A and the filter section C are arranged in this order, if the water vapor condenses in the hollow fiber 11 of the filter section C, the ventilation resistance increases. When it is necessary to avoid such an increase in ventilation resistance, it is preferable to arrange the aroma generating part B and the humidifying part A after the filter part C.

Further, in the humidifying part A, gas passes through the hollow part of the microporous hollow fiber 1, and also in the aroma generating part, gas passes through the hollow part of the multilayer composite hollow fiber 6. However, water may be placed in the hollow portion of the microporous hollow fiber, an aromatic agent may be placed in the hollow portion of the multilayer composite hollow fiber, and gas may be passed to the side in contact with the outer wall surface of the hollow fiber. It is preferable that the outer wall surface is brought into contact with water and the fragrance, because there is no drift of gas and the efficiency is good.

The filter portion C may also be constructed so that the direction of filtration of the gas by the hollow fiber 11 is the opposite direction to the illustrated example, that is, the gas is filtered by aeration from the hollow portion of the hollow fiber toward the outside of the hollow fiber.

Further, as the hollow fiber 11 of the filter portion C, only one end is opened and fixed by a fixing member,
The one with the other end sealed is also available. Further, when it is not necessary to avoid a temperature rise in the space for controlling humidity and aroma, a heating means such as a heater may be attached to an appropriate position of the device of the present invention.

[0050]

According to the air conditioner of the present invention, since it has an air purifying function, a deodorizing function, an aroma function, and a humidifying function, a comfortable living space can be formed. When the heating means such as a heater is not used in the air conditioner of the present invention, it is possible to provide an economical air conditioner having multiple functions, which is small, has high safety, and consumes less power.
