The present invention relates to a vehicle air conditioner having a negative / positive ion generator, and more particularly, a large amount of negative ions by electromagnetic radiation without generating secondary pollutants harmful to the human body, and without causing noise discharge. And the negative / positive ion generator which dissipates odors and various harmful substances contained in the air by dissipating cations evenly throughout the interior of the vehicle and at the same time exerts a bactericidal effect to keep the interior of the vehicle comfortable at all times. It relates to a vehicle air conditioner provided.

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 cabin.

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, 110, 111) , It consists of the vent (109, 110, 111) multiple mode door for selectively changing the flow direction of the air discharged through the (Mode Door, 112, 113, 114).

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. Alternatively, after passing through the heater core 107 through which the coolant of the vehicle engine flows and heat-exchanging, various directions of the vehicle interior in the cold or warm state through the vents (109, 110, 111) connected to each part of the vehicle interior. 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 by 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 a vehicle, which is intended by the driver or the passenger, and thus there is a problem in that the air in the vehicle can not 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 having an air inlet 201 and an air outlet 202, and air installed at an air inlet 201 in the case 200. A filter 203, a blowing fan (not shown) rotatably installed in the case 200, and an air discharge port installed in the case 200 via the air filter 203 from the air inlet 201 ( And a negative ion generator for generating negative ions to purify the air flowing to the side 202).

As shown in FIGS. 3A and 3B, the negative ion generator sets 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 generator generates ozone (O ₃ ), which is highly oxidative in generating negative ions and has a harmful effect 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.

On the other hand, Japanese Patent Laid-Open No. 2005-71715 has a negative / positive ion generator for purifying the air by generating positive ions in addition to the negative ions based on the fact that only negative ions can effectively remove floating bacteria in the air. An adjusting device is disclosed.

Figure 4 schematically shows a cross-sectional view of the air conditioner with a negative / positive ion generator according to the prior art described above.

As shown in Fig. 4, the negative / positive ion generator 306 according to the prior art is provided on the downstream side of the blowing fan 301 inside the air conditioner 300, and has a flat plate dielectric 302. And a grounding electrode 303 and an applying electrode 304 facing each other with the dielectric 302 interposed therebetween, and a voltage applying means 305.

The prior art is to purify the air using a negative / positive ion generator having such a structure. That is, when the voltage of the positive electrode and the negative electrode is alternately applied to the applying electrode by the voltage applying means, the dielectric 302 causes polarization to generate plasma discharge in the air layer in contact with the ground electrode. Accordingly, a plasma region is formed near the ground electrode to ionize or dissociate water molecules or oxygen molecules in the air to generate anions (O ₂ ⁻ ) and cations (H ₃ O ⁺ ), and the generated anions and cations are supplied to the blower fan. Air is blown to the proper space, and various kinds of fungi, harmful substances and odors suspended in the air are enclosed in the form of clusters to make the air clean.

However, since the negative / positive ion generator according to the prior art is a plasma discharge method in which the dielectric is directly discharged into the air by using a ceramic chip as a dielectric, there is a problem in that discharge noise is generated and in a small area. While the air purification efficiency is high, there is a problem that the air purification efficiency is low in a large area.

In particular, secondary discharges such as ozone (O ₃ ) and nitrogen oxides (NO _x ), which are harmful to the human body as the generated ion reacts with the active oxygen (O ⁺ ) in the air as well as the amount of generated ions less. , there is a problem that results in the opposite effect by ^-: (+ O ⁺ O ₃ → O ₂ for example) to occur.

Accordingly, the present invention has been made to solve the above conventional problems, and does not generate secondary pollutants harmful to the human body, and also generates a large amount of anions and cations by electron radiation without causing discharge noise. Its purpose is to distribute the odor evenly to all parts of the room, to remove odors and various harmful substances contained in the air, and to exert a disinfecting effect so that the environment inside the vehicle can be always maintained comfortably.

(First embodiment)

The present embodiment applies the cluster negative / positive ion generator according to the present invention to a three piece type air conditioner independently configured with a blower unit, an evaporator, and a heater core.

As shown in FIG. 5, the air conditioning case 10 of the air conditioner having such a structure includes a first case 10a including a blower unit 13, an air filter 16, and an evaporator 17. A second case 10b and a third case 10c including a heater core (not shown) are formed.

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 10b 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 the outlet side of the second case 10b to selectively select air introduced through the evaporator 17 by a temperature control door (not shown). Heater core (not shown) for heat exchange with a plurality of vents, a plurality of vents (18, 19, 20) for discharging air to the respective parts of the interior of the vehicle is installed.

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 anion and the positive ions flow together in the air flowing into the air conditioning case to sterilize and purify the interior air. It is characterized in that the cluster negative / negative ion generator (30, see Fig. 6) is installed to create a comfortable indoor environment.

Here, unlike the conventional corona discharge method or the plasma discharge method, the cluster negative / positive ion generator 30 according to the present invention is provided with a pair of discharge electrodes having a positive electrode and a negative electrode. An electron emission method is adopted in which air is used as a dielectric to discharge electrons from the discharge electrodes. That is, the cluster negative / positive ion generator 30 applies a high voltage pulse (a high voltage but a small amount of energy) to a pair of discharge electrodes to radiate electrons directly in the air, thereby radiating electrons without causing noise. It is an ion generator that combines with oxygen and moisture in the air and generates a large amount of cluster anions and cations, but does not generate secondary pollutants such as ozone and nitrogen oxides that are harmful to the human body.

6 (a) and 6 (b) show the structure of the cluster negative / positive ion generator as viewed from the bottom. As shown in FIGS. 6 (a) and 6 (b), the cluster negative / positive ion generators are formed on the high voltage generator 31 and the side portions of the high voltage generator 31 for generating a high voltage pulse, respectively. A main body 33 having fastening portions 32 (only two are shown in the drawing) having fastening holes 32a; A power input unit 34 formed of a negative (-) pole line 34a and a positive (+) pole line 34b respectively connected to an upper end side of the high voltage generator 31; The high voltage generator 31 includes a pair of discharge electrodes 35 and 36 connected to one side of the lower surface of the high voltage generator 31.

The power input unit 34 may be electrically connected to a control switch installed in the instrument panel in the vehicle compartment to automatically control the generation of negative ions and positive ions during cooling or heating operation. Alternatively, the power input unit 34 may be connected to the start switch IGN to continuously generate negative ions and positive ions when the vehicle is started.

The pair of discharge electrodes 35 and 36 may generate the 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. The first high voltage output line 35a having a predetermined length connected to the generator 31 and the negative ion generator having a predetermined length having a metal fiber shape composed of an alloy of various metal components at the end of the first high voltage output line 35a ( A first discharge electrode 35 made of 35b); And a predetermined distance from the first high voltage output line 35a to generate cluster cations by a large amount of electrons discharged by the high voltage pulse applied from the high voltage generator 31 through the power input unit 34. a cation generator having a metal fiber shape composed of an alloy of various metal components at the end of the second high voltage output line 36a and the second high voltage output line 36a connected to the high voltage generator 31. And a second discharge electrode 36 composed of 36b).

The anion generator 35b and the cation generator 36b each have a brush shape in order to increase the surface area of the discharge, and the amount of anion and cation generated according to the voltage size of the high voltage generator 31. You can control the enemy.

Here, the interval d between the second discharge electrode 35 and the second discharge electrode 36 is preferably maintained within the range of 2 to 5 cm in consideration of electrical safety, bactericidal (or antimicrobial), and ion generation amount. If the distance d is less than 2 cm, there is a risk of sparks due to contact between brushes when ions are generated from the anion generator 35b and the cation generator 36b. In addition, when the interval d exceeds 5 cm, ions generated from the anion generating unit 35b and the cation generating unit 36b are widely dispersed, resulting in a decrease in sterilization. Preferably, the distance d between the first discharge electrode 35 and the second discharge electrode 36 is 3 cm.

In order to evaluate the bactericidal power of the test strain according to the interval between the discharge electrodes, after spraying a certain amount of Aspergillus niger or Escherichia coli as the test strain in the test vessel of 500mm × 700mm × 500mm The internal air was collected by time, and the collected air was incubated, and then the residual ratio of the test strain was measured by the cluster negative / positive ion generator. At this time, 12V power was applied to the cluster negative / positive ion generator.

7 shows the results.

First, Figure 7 (a) shows the sterilization power according to the operating time of the cluster negative / positive ion generator when using the mold as a test strain, Figure 7 (b) shows the cluster negative when using E. coli as the test strain It shows the sterilizing power according to the operating time of cation generator.

As can be seen from FIGS. 7A and 7B, when the distance d between the first discharge electrode 35 and the second discharge electrode 36 is 3 cm, the sterilizing power is the best. have. This means that making the distance d between the first discharge electrode 35 and the second discharge electrode 36 as small as possible is advantageous in terms of the efficiency of the sterilizing power.

On the other hand, on the lower surface of the high voltage generator 31 in which the first high voltage output line 35a and the second high voltage output line 36a are provided, a circular first opening 30a-1 and a first opening 30a-1 are provided. Openings 30a formed of the second openings 30a-2 extending in the horizontal direction are formed at both sides of the cross-section. At certain portions of the first high voltage output line and the second high voltage output line, a cylindrical body 37a corresponding to the shape of the first opening 30a-1 so as to be unlockably locked to the opening 30a by a rotation method; Locking portions 37 having upper and lower wing portions 37b and 37c protruding in the horizontal direction corresponding to the second openings 30a-2 at regular intervals above and below both sides of the cylindrical body 37a are provided. It is characterized by being provided integrally.

As a result, the locking part 37 arranges the wing parts 37b and 37c in a direction parallel to the second opening 30a-2, and the lower wing part 37c of the wing parts 37b and 37c. After the bay is inserted into the high voltage generator 31 and rotated by 90 ° as shown in Fig. 6A, the lower surface of the upper wing 37b of the wing portions 37b, 37c is It is fastened by being supported on the upper surface of the high voltage generator 31. In addition, when the locking portion 37 is reversed in the above-described operation, the locking portion 37 can be released from the opening 30a as shown in FIG.

The reason for providing the locking portion 37 having such a structure is that when the anion generating portion 35b and the cation generating portion 36b are to be installed at the air purifying position, a predetermined length is provided above the locking portion 37. In the case where the first high voltage output line 35a and the second high voltage output line 36a each have a short length and are difficult to be installed at the position, the locking portion 37 is released as described above, so that the high voltage generating portion 31 is released. The extra first high voltage output line 35a and the second high voltage output line 36a which are accommodated are drawn out to adjust the length thereof appropriately.

In the present invention, the anion and the cation are simultaneously generated through the anion generator 35b and the cation generator 36b installed at the air purification target position as described above, and, if necessary, the anion generator 35b and the cation generator ( Only one of 36b) can be controlled to generate only anions or cations.

As described above, the cluster negative / positive ion generator 30 according to the present invention includes the positive ion of the negative electrode generator 35b of the first discharge electrode 35 and the positive electrode of the second discharge electrode 36 through the high voltage generator 31. Applying electrical energy to the generator 36b causes electron radiation to the air over a large surface area of the anion generator 35b and the cation generator 36b, combined with oxygen and moisture in the air, To generate cations. Therefore, harmful substances such as various bacteria, fungus bacteria, and odors contained in the air are surely removed by such cluster anions and cations.

Such a cluster anion and cation generating mechanism will be described in more detail as follows.

When the high voltage pulse current, which is a strong negative electric charge, is applied to the negative ion generating unit 35b of the first discharge electrode 35 through the high voltage generating unit 31 and electrons are radiated into the air, Moisture (H ₂ O) is debonded to generate hydrogen and anions as shown in Equation (1), and at the same time, air is applied by applying a high voltage pulse current, which is a strong positive electrode, to the cation generator 36b of the second discharge electrode 36. When electrons are radiated to the middle, water (H ₂ O) in the air deprives electrons and generates oxygen and cations as shown in Equation (2).

^{_{2H 2 O + e - → 4H}} + O 2 - ‥‥ (1)

As described above, the anions (O ₂ ⁻ ) and cations (H ⁺ ) discharged into the air are unstable, so they combine with water molecules in the air to form cluster ions such as grape clusters, that is, H ₃ O ⁺ (H ₂ O) _n (n is any natural number) and O ₂ ⁻ (H ₂ O) _m (m is any natural number).

These cluster ions surround the harmful substances suspended in the air and chemically react with the surrounding water molecules to form active species such as hydrogen peroxide (H ₂ O ₂ ), hydrogen phosphate (HO ₂ ), or the like, as shown in Eqs. (3) and (4). Produces hydroxy radicals (.OH).

^{_{H 3 O + (H 2 O}} ) n + O 2 - (H 2 O) m → · OH + H 2 O 2 + (n + m) H 2 O ‥‥ (3)

^{_{H 3 O + (H 2 O}} ) n + O 2 - (H 2 O) m → HO 2 + H 2 O + (n + m) H 2 O ‥‥ (4)

Hydrogen peroxide (H ₂ O ₂ ), hydrogen phosphate (HO ₂ ), or hydroxy radicals (.OH) produced in this way exhibit strong activity, and thus deprive hydrogen (H) in various harmful substances or odors in the air membranes. It is converted into water molecules (H ₂ O), at which time harmful substances and odors from which hydrogen (H) is removed from the cell membrane are destroyed by the cell membrane and are inactivated and converted into harmless substances.

As described above, the cluster negative / cation generator 30 according to the present invention generates a large amount of cluster ions, but does not generate secondary pollutants such as ozone (O ₃ ) and nitrogen oxides (NO _x ). In addition to the deodorizing and sterilizing effect, it is to continuously release the air beneficial for the metabolic activity of the human body.

Therefore, the present invention, without the need to use a separate air purifier as in the prior art, by installing a cluster negative / positive ion generator to function in the air conditioning apparatus, it is completely purified with the air filter installed inside the air conditioning apparatus There is an advantage that can release the air into the cabin. Moreover, according to the present invention, the intended effect can be sufficiently exhibited by removing the air filter and providing only the cluster negative / positive ion generator.

The cluster negative / positive ion generator 30 may be mounted at various places according to the sterilization and purification targets when installed in the air conditioner.

For example, as shown in FIG. 5, by installing the blower unit 13 in front of the blower unit 13 in the first case 10a, the air initially introduced into the first case 10a by the blower unit 13 is original. Can be purified.

Here, in mounting the cluster negative / positive ion generator 30 to the first case (10a), the main body of the first case (10a) by a fixing means such as a screw fastened through the fastening portion (32). It is preferable to be fixed to the outer bottom and to be installed such that only the anion generating part 35b and the cation generating part 36b are inserted into the first case 10a.

That is, as shown in FIG. 8, the anion generator 35b and the cation generator 36b are separate holders 40-40 that support the anion generator 35b and the cation generator 36b, respectively. A state of being inserted through the first insertion hole (10a-1) and the second insertion hole (10a-6) formed at a predetermined distance to the predetermined position of the first case (10a) using 1, 40-2, respectively Is assembled.

First, before explaining the structures of the holders 40-1 and 40-2, the structure of the case 10a, which is the site where the holders 40-1 and 40-2 are assembled, will be described.

On one side of the first case 10a according to the present invention, a pair of cylindrical walls 10a-2 and 10a-7 are protruded at a predetermined distance, and the cylindrical walls 10a-2 and 10a-7 are formed. The first insertion hole 10a-1 and the second insertion hole 10a-6, which are open to the inside of the first case 10a, are formed at each center of the first case 10a, and the first insertion hole 10a-1. And on each inner circumferential surface of the second insertion hole 10a-6, hemispherical first and second locking portions 10a-3, 10a-4; 10a-8, 10a-9 are formed at staggered positions. The position angles θ of the first locking portions 10a-3 and 10a-8 and the second locking portions 10a-4 and 10a-9 are approximately 90 ° to 180 °, preferably 150 °. to be.

On the other hand, since the holders 40-1 and 40-2 have the same structure, the same reference numerals are given to the same components.

The holders 40-1 and 40-2 may seal the first insertion holes 10a-1 and the second insertion holes 10a-6 and the second insertion holes 10a-1 and the second insertion holes 10a-1. Cover portion 41 having an outer diameter larger than the inner diameter of the insertion hole (10a-6), and integrally coupled to one surface of the cover portion 41 to form a right angle with the cover portion 41 to the insertion hole (10a-) Protruding by the length of 1), the cylindrical projection having a smaller than the outer diameter of the cover portion 41 to be inserted into the insertion hole (10a-1) and having an outer diameter substantially corresponding to the inner diameter of the insertion hole (10a-1) It is composed of a 42 and a plate-shaped handle portion 43 for integrally coupled to protrude to the other surface of the cover portion 41 for gripping during assembly work.

In addition, the projection 42 has a "U" shaped insertion groove 44 in which the negative ion generating part 35b is inserted and supported in a radial direction, and the "U" shaped insertion groove 44. ) 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 8, 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 that the holders 40-1 and 40-2 are assembled into the first insertion hole 10a-1 and the second insertion hole 10a-6. This is to prevent misassembly due to carelessness of the city worker. That is, when the holders 40-1 and 40-2 are initially inserted into the first insertion hole 10a-1 and the second insertion hole 10a-6, the precise insertion position can be determined and, of course, the insertion. The half of the cover portion 41 is formed in a substantially triangular shape to serve as a guide for determining the assembling direction of the holders 40-1 and 40-2 according to the position, and the portion is a guide for assembly positioning. It acts as (41b).

According to the structure of the cover portion 41, the first insertion hole (10a-1) and the second insertion hole (10a-6) is formed to protrude on one side of the first case (10a) to open to the inside of the air conditioning case The walls 10a-2 and 10a-7 having) are formed in a shape corresponding to the assembly positioning guide portion 41b as shown in FIG. 8.

As described above, between the walls 10a-2 and 10a-7 having relatively large arcs and the first insertion hole 10a-1 and the second insertion hole 10a-6, a weight loss groove ( 10a-5, 10a-10) are formed. Moreover, the insides of the walls 10a-2 and 10a-7 are inward as much as the thickness of the cover portions 41 to accommodate the cover portions 41 of the holders 40-1 and 40-2. It is structured slightly.

Further, the protrusion 42 has a first and second guide grooves 42a, 42b, and FIG. 9 of asymmetrical structure in the circumferential direction with the U-shaped insertion groove 44 formed in the radial direction therebetween. 9 and 10 illustrate only the structure of one holder 40-1 for the sake of simplicity of the drawings, the following description of FIG. 9 and FIG. The same applies to 40-2).

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. 9, 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. 9. 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.

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.
