The present invention relates to a vehicle air conditioner having a cluster anion generator, and more particularly, by installing a cluster anion generator that does not generate ozone harmful to a human body in a general air conditioner without installing a separate air cleaner in a vehicle cabin. In addition, it removes odors and various harmful substances contained in the air while driving, and generates a large amount of negative ions that have a sterilizing effect so that it is evenly distributed throughout all parts of the vehicle, so that the environment inside the vehicle can be always maintained comfortably. A vehicle air conditioner having a cluster anion generator.

In recent years, as the number of vehicles owned increases and the atmospheric environment becomes worse, the desire to keep the interior of the automobile in a comfortable state has gradually increased.

In general, when driving a vehicle, bacterial particulates such as dust, dust, and pollen generated on the road, and various harmful substances such as sulfurous acid gas (SO ₂ ), nitrogen compound (NO _X ), and carbon monoxide (CO) present in contaminated air This will flow into the interior of the car. In particular, when the heater or air conditioner is operated on a cold or wet day, odors and bacterial particles generated at this time are introduced into a differential vehicle called a cabin (Cabin) as it is, causing discomfort to a driver or a passenger.

Accordingly, the air conditioner for automobiles is equipped with an air filter for supplying purified air to a driver or a passenger by preventing the above-mentioned bacterial particulates or harmful substances from entering the vehicle interior.

1 is a view schematically showing the interior of a general automotive air conditioner.

As shown in FIG. 1, a general vehicle air conditioner includes an air inlet 101 or an outdoor air inlet 102 according to an opening / closing selection of an indoor / outdoor air conversion door 103. Blower unit (104) for selectively suctioning into (100), an evaporator (106) for cooling the air blown from the blower unit (104) by driving the electric motor (105), and the evaporator ( A heater core 107 installed adjacent to the heater 106 to heat the air, and installed between the evaporator 106 and the heater core 107 to adjust the temperature of the air discharged into the cabin according to the opening / closing angle. Temp door 108 for adjustment and a plurality of vents connected to each part in the vehicle interior to discharge the cooled or heated air to each part of the vehicle interior according to the opening / closing selection of the temporal door 108. (Vent, 109, 1110, 111) And a plurality of mode doors (Mode Doors 112, 113, 114) for selectively changing the flow direction of the air discharged through the vents (109, 110, 111).

In the vehicle air conditioner configured as described above, the evaporator 106 through which the refrigerant flows through the temporal door 108 through the air sucked into the air conditioning case 100 by the driving of the electric motor 105 of the blower unit 104. Or heat exchange by selectively passing through the heater core 107 through which the coolant of the vehicle engine flows, and then through the vents 109, 1110, and 111 connected to the respective parts of the vehicle interior in a cold or warm state. By distributing to the air conditioner, the heating and cooling of the vehicle interior is achieved.

In the vehicle air conditioner as described above, in order to purify the air flowing into the vehicle cabin, the air inlet 101 side, upstream side of the blower unit 104 or between the blower unit 104 and the evaporator 106 (Air) Filter, 115) is fixed.

Examples of the air filter 115 include a dust removing filter for filtering bacterial fine particles such as dust, an odor removing filter for removing odor components such as odor, and an integrated filter integrating the dust removing filter and odor removing filter. There is. Among these, the odor removing filter or the integrated filter is configured to physically adsorb and filter harmful substances in the air using activated carbon particles, for example, to perform deodorization or deodorization in an external air inflow mode or an internal circulation mode. have.

However, the filter as described above, when a certain period of use has elapsed, the odor component is adsorbed and trapped in the fine pores of the activated carbon to reach the saturation state, the odor adsorbed in the high temperature state by gradually losing the adsorption power of the filter Partial re-emission of the components into the interior of the vehicle may eventually cause discomfort to the occupant. In particular, when driving in a state in which the interior is sealed with the outside during the rainy season in summer, the adsorption power of the filter is limited due to the high temperature air flowing from the outside air, and the odor component adsorbed on the filter surface is easily desorbed, thereby operating the air conditioner. There was a problem that the air cleanliness in the interior is greatly reduced as the bad smell is introduced into the vehicle interior.

Moreover, such a filter can only perform a function of simply filtering irrespective of the air purifying state in the cabin intended by the driver or the passenger, and thus there is a problem in that the air in the cabin cannot play any role.

Accordingly, the driver or passenger frequently opens a window to ventilate the air, or separately installs an air cleaner in an appropriate position in the cabin, for example, an instrument panel in front of the vehicle or a shelf behind the rear seat of the vehicle. Purifies the air inside the car.

In recent years, in consideration of health aspects, there is a tendency to use a lot of air cleaners that can release negative ions beneficial to the human body in the vehicle interior.

2 shows an example of such an air cleaner.

As shown in FIG. 2, the air purifier includes a case 200 including an air inlet 201 and an air outlet 202, and an air inlet 201 in the case 200. An air filter 203, a blowing fan (not shown) rotatably installed in the case 200, and an air discharge port installed in the case 200 via an air filter 203 from an air inlet 201. And a negative ion generating device for generating negative ions so as to purify the air flowing to the 202 side.

As shown in FIGS. 3A and 3B, the anion generator includes the needle-shaped discharge electrode 210 as the negative electrode and the ground electrode 211 opposite thereto as the positive electrode. A high DC voltage is applied between the 210 and the ground electrode 220 to generate a corona discharge between the anodes, thereby releasing a large amount of electrons into the air. A large amount of electrons emitted in this manner collides with oxygen and moisture in the air and anionizes the oxygen and moisture to purify the air.

However, such an anion generating device generates ozone (O ₃ ), which is highly oxidizing and generates harmful effects on the human body due to the silent discharge in which discharge occurs between the anodes by applying a high voltage as described above. Resulted.

The basic reaction equation for ozone generation by the silent discharge is as follows.

^{_{O 2 + e - → O +}} O + e -

O + O → O ₂

O + O ₂ + M → O ₃ + M

O ₂ + O ₂ → O ₃ + O

As described above, oxygen is generated through discharge of ozone, and the generated ozone is reduced to oxygen by working with pollutants. When used as an oxidant, such ozone leaves no harmful residues at all, and has a strong sterilizing power to remove bacteria and viruses, and to have a strong bleaching effect, as well as organic substances such as cigarette smoke and other odorous gases and various harmful substances. It reacts with and has the effect of harmlessness, but also causes harmful effects on the human body.

This ozone has a serious effect on children, the elderly, and heart patients, and one of the dangerous gases that the increase of 0.1ppm ozone increases the number of deaths by 7%. For this reason, each country is strongly regulated by specifying the allowable concentration of ozone.

As described above, the conventional negative ion generating air cleaner has a problem of generating negative ions at the same time by silent discharge and inevitably generating ozone which is a by-product. In particular, a low voltage should be used to reduce the ozone generation. In this case, rather less anion is generated, there is a problem that can not fully exhibit the effect of air purification in the originally intended vehicle interior.

Accordingly, the present invention has been made to solve the above-mentioned problems, and installs a cluster negative ion generator that does not generate ozone in a general air conditioner without installing a separate air purifier in the vehicle cabin, Its purpose is to remove the odors and various harmful substances contained in it, and to generate a large amount of negative ions that have a bactericidal effect, so that they are evenly distributed throughout the inside of the car, thereby keeping the environment inside the car always comfortable. have.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

(First embodiment)

In this embodiment, the cluster anion generator according to the present invention is applied to a three piece type air conditioner having a blower unit, an evaporator, and a heater core independently.

As shown in FIG. 4, the air conditioning case 10 of the air conditioner having such a structure includes a first case 10a including a blower unit 13, an evaporator 15, and an air filter 16. It consists of a 2nd case 10b and the 3rd case 10c containing a heater core (not shown).

The first case 10a is an internal / external air inlet door (not shown) for controlling the opening degree of the internal air inlet 11 and the external air inlet 12 formed on the air inlet side, and the internal and external air inlet by the electric motor 14. The blower unit 13 which introduces internal and external air (henceforth simply "air") from the furnaces 11 and 12 and blows it toward the evaporator 17 side is provided.

The second case 10c is connected to the blowing duct 15 of the first case 10a, and has an evaporator 17 for cooling the air blown by the blower unit 13 therein, It is provided with an air filter 16 for adsorption and removal of foreign matter contained in the blown air.

In addition, the third case 10c has an inlet end connected to an outlet side of the second case 10b, and a heater core (not shown) for selectively heating the air introduced through the evaporator 17. ), And a plurality of vents (18, 19, 20) for discharging air to each part of the vehicle interior is installed at the outlet end.

In the air conditioner having such a structure, when the air conditioner or the heater is operated to cool or heat the interior of the vehicle, the present invention flows negative ions to the air flowing into the air conditioning case together to sterilize and clean the interior air It is characterized in that the cluster negative ion generator 30 (see Fig. 5) is installed to create an indoor environment.

Here, unlike the conventional corona discharge method, the cluster anion generator 30 according to the present invention does not provide a ground electrode to be a positive electrode, but only a discharge electrode to be a negative electrode. Electrospinning is used to emit electrons from the electrodes. That is, the cluster anion generator applies a high voltage pulse (a high voltage but a small amount of energy) to the discharge electrode to radiate electrons directly in the air, so that the emitted electrons are combined with oxygen and moisture in the air, thereby providing a large amount of clusters. ) Ozone cluster anion generator that generates anions and does not generate ozone.

As shown in FIG. 5, the cluster negative ion generator has a high voltage generating part 31 for generating a high voltage pulse and a high voltage generating part 31 formed at both ends of one side of the high voltage generating part 31. A main body 33 having a government unit 32; A power input unit (34) comprising negative (-) poles (34a) and positive (+) poles (34b) respectively connected to the upper ends of the high voltage generators (31); A ground part 35 connected to the other lower end of the high voltage generator 31 and grounded to a battery; And a discharge electrode 35 connected to one lower end of the high voltage generator 31.

The power input unit 31 may be electrically connected to a control switch installed on an instrument panel in a vehicle room for proper control of negative ion generation so that negative ions are automatically generated during cooling or heating operation. Alternatively, the power input unit 31 may be connected to the start switch IGN to continuously generate negative ions when starting the vehicle.

The discharge electrode 36 is a high voltage output line 36a so as to generate a cluster anion by a large amount of electrons discharged by a high voltage pulse applied from the high voltage generator 31 through the power input unit 34. And an anion generator 36b having a metal fiber shape composed of an alloy of various metal components at the end of the high voltage output line 36a. The negative ion generating unit 36b has a brush shape to increase the surface area of the discharge, and can adjust the amount of negative ions generated according to the voltage size of the high voltage generating unit 31.

As described above, the cluster negative ion generator 30 according to the present invention applies the electrical energy to the negative ion generator 36b of the discharge electrode 36 through the high voltage generator 31, as shown in FIG. While generating electron radiation in the air over a large surface area of the negative ion generating unit 36b, it combines with oxygen and moisture in the air to generate a large amount of cluster anions. Therefore, harmful substances such as various bacteria, fungus bacteria, and odors contained in the air are surely removed by such cluster anions.

The cluster anion generation mechanism as described above will be described in more detail.

When the high voltage pulse current is applied to the negative ion generating unit of the discharge electrode 36 through the high voltage generating unit 31 to emit electrons into the air, the moisture (H ₂ O) in the air is released by the electrons released together with the thermal energy. It is decomposed into ions (H ⁺ ) and hydroxyl ions (OH ⁻ ), and at the same time, ozone anions (O ₃ ⁻ ) are generated on the fiber surface of the anion generating unit 36b. The hydrogen ions (H ⁺ ) and hydroxyl ions (OH ⁻ ) are continuously generated every tens of thousands through anion generators, and are surrounded by water fine particles in the air, so-called grape clusters. To form cluster ions.

Here, the ozone anion is a hydroxyl group (OH ^-) fruit acid anion reacts with the ^{_{(Perhydroxyl Radical Anion; HO 2 -}} ) and a strong acid chemical conversion anion ^{_{(Superoxide Radical Anion: O 2 -}} ) to be decomposed, the strong acid chemical conversion anion (O ^₂₎ after the formation of the cluster ion in combination with water again, hydroxide ions (OH ^- form a). The thus formed hydroxide ions (OH ^-) are toxic substances who took the hydrogen (H) in the cell membranes of various harmful substances or odors from the air is converted into a water molecule (H ₂ O), to remove the hydrogen (H) at this time, the cell membrane And odors are disrupted by cell membranes and converted into harmless substances.

As described above, the cluster anion generator 30 according to the present invention generates a large amount of cluster anions, but does not generate ozone, so that in addition to the deodorizing and disinfecting effects, it is possible to continuously release the air beneficial for the metabolic activity of the human body. .

Therefore, the present invention, by using a cluster anion generator that functions as described above in the air conditioner, without having to use a separate air purifier as in the prior art, by using the air filter installed inside the air conditioner completely purified air There is an advantage that can be released into the cabin.

Such a cluster anion generator 30 is provided in front of the blower unit 13 in the first case 10a, for example, as shown in FIG. The air initially introduced into 10a) can be purified at its source.

Here, in mounting the cluster negative ion generator 30 to the first case (10a), the main body is the outer bottom surface of the first case (10a) by a fixing means such as a screw fastened through the fixing portion (32). It is preferable that the negative electrode generator 36b of the discharge electrode 36 is inserted into the first case 10a.

That is, the negative ion generator 36b is inserted at a predetermined position of the first case 10a by using a separate holder 40 supporting the negative ion generator 36b as shown in FIG. 7. Assembled in the inserted state through the ball (40).

First, before explaining the structure of the holder 40, the structure of the case 10a, which is the site where the holder 40 is assembled, will be described.

One side of the first case 10a according to the present invention has a cylindrical wall 10a-2 protruding, and is opened to the inside of the first case 10a at the center of the cylindrical wall 10a-2. The insertion hole 10a-1 is formed, and hemispherical first and second locking portions 10a-3 and 10a-4 are formed at staggered positions on the inner circumferential surface of the insertion hole 10a-1. . The position angle θ of the first locking portion 10a-3 and the second locking portion 10a-4 is approximately 90 ° to 180 °, and preferably 150 °.

On the other hand, the holder 40, the cover portion 41 having an outer diameter larger than the inner diameter of the insertion hole (10a-1) to seal the insertion hole (10a-1), and the cover portion 41 The cover portion 41 is integrally coupled to one surface of the cover portion 41 so as to be perpendicular to the cover portion, and protrudes the length of the insertion hole 10a-1, and is inserted into the insertion hole 10a-1. Cylindrical protrusion 42 having a smaller outer diameter than the inner diameter of the insertion hole 10a-1 and having an outer diameter substantially corresponding to that of the insertion hole, and integrally coupled to protrude to the other surface of the cover 41 to be gripped during assembly work. It consists of a plate-shaped handle part 43 for this purpose.

The protrusion 42 has a U-shaped insertion groove 44 in which the negative ion generator 36b is inserted and supported in a radial direction, and the U-shaped insertion groove 44 is formed therein. ) Is connected to the circular cover portion 41, and, on one surface of the handle portion 43 is a straight groove 43a is formed in the same direction as the direction of the "U" -shaped insertion groove 44 It is.

In addition, the lid portion 41, as shown in Figure 7, the half portion 41a is formed in a hemispherical shape, the other half portion 41b is formed in a substantially triangular shape with respect to the insertion groove 44. The reason why the cover portion 41 is formed in such an asymmetrical structure is to prevent misassembly due to the carelessness of the operator when assembling the holder 40 to the insertion hole 10a-1. That is, when the holder 40 is initially inserted into the insertion hole 10a-1, the precise insertion position can be determined and, of course, the guide 40 can determine the assembly direction of the holder 40 according to the insertion position. The half of the cover portion 41 is made to have a substantially triangular shape so that the portion serves as the assembly positioning guide portion 41b.

According to the structure of the cover part 41, the wall 10a-2 having the insertion hole 10a-1 which protrudes on one side of the first case 10a and opens to the inside of the air conditioning case is shown in FIG. As shown in Fig. 7, the assembly is made in a shape corresponding to the assembly positioning guide portion 41b.

As can be clearly seen from FIG. 7, the wall 10a-2 includes a cover 41 for inserting the holder 40 into the insertion hole 10a-1 to seal the insertion hole 10a-1 during assembly. The part near the part farther away from the center point of the insertion hole 10a-1, so that the approximately triangular assembly positioning guide part 41b of the triangle can be smoothly rotated in the assembly direction without any interference. It is formed in a structure having a relatively large arc. As described above, a weight loss groove 10a-5 for reducing weight is formed between the wall 10a-2 having the relatively large arc and the insertion hole 10a-1. Moreover, the inside of the wall 10a-2 has a structure that is slightly inwardly as thick as the cover portion 41 to accommodate the cover portion 41 of the holder 40.

Further, the protrusions 42, as shown in Figs. 7 and 8, the first and first of the symmetrical structure in the circumferential direction with the insertion groove 44 of the 'U' shaped in the radial direction therebetween 2 guide grooves 42a and 42b are formed, respectively.

When the first and second guide grooves 42a and 42b are rotated after the protrusions 42 are inserted into the insertion holes 10a-1 of the first case 10a as described below, As the protrusion 42 rotates, the first and second catching portions 10a-3 and 10a-4 fixed to the insertion hole 10a-1 are formed to pass therethrough. However, as shown in FIG. 8, the first and second guide grooves 42a and 42b have a structure in which both ends are not connected to each other in order to limit the continuous rotation of the protrusion 42.

The first and second guide grooves 42a and 42b having this function include the “U” shaped insertion grooves 44 formed in the radial direction of the protrusions 42, as shown in detail in FIG. 8. As a reference, in the distal end portion of the first guide groove 42a located near the U-shaped insertion groove 44, the first formed in the insertion hole 10a-1 of the first case 10a. The first receiving groove 45a for accommodating the first locking portion 10a-3 is formed, and the distal end portion of the second guide groove 42b located far from the insertion groove 44 of the “U” shape. The second receiving groove 45b for accommodating the second locking portion 10a-4 formed in the insertion hole 10a-1 is formed therein.

The first accommodating groove 45a is formed at a side proximate to the “U” shaped insertion groove 44, and the second accommodating groove 45b is located at a far side from the “U” shaped insertion groove 44. Formed. That is, the position angles at which the first accommodating groove 45a and the second accommodating groove 45b are formed may correspond to the positions at which the first catching portion 10a-3 and the second catching portion 10a-4 are formed. Similarly, it is 90 degrees-180 degrees, Preferably it is 150 degrees.

In addition, the first and second receiving grooves 45a and 45b may have the first and second catches when the protrusion 42 is first inserted into the insertion hole 10a-1 of the first case 10a. It extends from the end of each said receiving groove 45a, 45b to the cross section of the said projection part 42 so that the parts 10a-3 and 10a-4 may be accommodated, respectively, The extended part is the said 1st and 1st 2 It has a shape corresponding to the shapes of the locking portions 10a-3 and 10a-4.

The distal end of the first guide groove 42a and the distal end of the second guide groove 42b are caught in a state of accommodating the hemispherical first and second locking portions 10a-3 and 10a-4. First and second locking grooves 46a and 46b are formed, respectively.

The forming positions of the first and second engaging grooves 46a and 46b are formed at staggered positions, similar to the forming positions of the first and second receiving grooves 45a and 45b.

That is, referring to FIG. 8A, the second locking groove 46b and the first locking groove are formed on the left and right sides of the “U” shaped insertion groove 44 adjacent to the “U” shaped insertion groove 44. In the left and right sides of the first receiving groove 45a far from the “U” shaped insertion groove 44, a second receiving groove 45b and a first locking groove 46a are formed. The second locking grooves 46a and 46b have a deeper structure than the first and second receiving grooves 45a and 45b, respectively.

Furthermore, the first guide groove 42a is narrower in width from the first receiving groove 45a formed at the distal end toward the first locking groove 46a formed at the distal end thereof, and the second guide groove 42b is provided. ) Has a structure in which the width becomes narrower from the second receiving groove 45b formed at the distal end toward the second locking groove 46b formed at the distal end thereof.

As the width of the first and second locking grooves 46a and 46b is formed on a portion of the guide groove that is narrower as described above, the first and second locking grooves 46a and 46b are deeper than the groove depths of the first and second receiving grooves 45a and 45b. First and second locking projections 47a and 47b having a stepped structure are formed at portions where the guide groove and the first and second locking grooves 46a and 46b are narrowed, respectively.

Hereinafter, the assembling method of the holder 40 according to the present invention will be described in detail with reference to FIGS. 8 and 9.

8 and 9 show before and after assembling of the holder 40 in a state where the anion generator 36b is not attached to the holder 40.

First, as shown in FIGS. 8A and 9A, in order to insert the holder 40 into the insertion hole 10a-1 of the air conditioning case, an anion generator 36b is inserted.
