TECHNICAL FIELD [0001] The present invention relates to an air conditioner for an automobile,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioner, and more particularly, to a vehicular air conditioner having a guide plate and an engagement hole formed in an aspirator coupling portion formed in an air conditioning case, To facilitate the engagement of the lighter and to improve the intake flow rate of the air.

The car is equipped with an air conditioner for controlling the temperature of the room air. The air conditioner warms the room by generating warmth in winter, and keeps the room cool by generating cold in summer.

Such an air conditioner is usually equipped with a heating system and a cooling system so that the inside or outside of the vehicle is heated or cooled by selectively introducing outside air or inside air and then heating or cooling the air.

1 and 2, the vehicular air conditioning system 10 includes a blowing fan 12, a blowing motor 14, and a scroll case 16 (not shown) for introducing the inside / outside air required for cooling / An evaporator 20 for converting the air conveyed from the blower 18 to cool air by heat exchange and a heater core 20 for converting ambient air into warm air by heat exchange between the high- Heater Core 22).

Between the evaporator 20 and the heater core 22, there is provided a temperature control door 24 for controlling the blowing amount of air by proper mixing of cold / warm air.

The air conditioning case 35 is provided with a defrost vent 26, a face vent 28, and floor vents 30 so that the air / have. The vents 26, 28, 30 are provided with respective doors 32, 34, 36 so as to control the blowing amount.

Such a vehicle air conditioner is configured such that when a driver operates a blowing mode changeover switch (not shown) provided at a predetermined position of an instrument panel 42, the inside / outside air is discharged through the vents 26, To be introduced into the room.

In recent years, automobile systems are becoming more and more automated and electronic in order to create a more convenient and pleasant driving environment and promote safe driving.

Accordingly, the automotive air conditioner is widely used, and in such an electronic air conditioner, when the temperature required by the driver is set, air having a temperature suitable for the temperature is introduced into the passenger compartment. Therefore, since the driver does not need to operate the air conditioner during operation of the vehicle, it can help the safe driving.

As shown in Fig. 2, the inciner sensor 52 among the sensors of the electric-powered air conditioning apparatus is mounted on the instrument panel 42 to which the air conditioning operation panel 40 is attached so as to measure the air temperature in the vehicle interior . The incase sensor 52 is installed in the suction hole 56 formed in the sensor connector 54 of the sensor unit 50. [

The sensor connector 54 provided with the incase sensor 52 is connected to the earthpirator 61 provided at one side of the air conditioning case 35 between the evaporator 20 and the heater core 22 by the aspiration hose 60, Lt; / RTI >

The earthpirator 61 generates a negative pressure under the influence of the blowing pressure passing through the evaporator 20 by the Venturi principle. The negative pressure generated by the above-described earthpirator 61 causes the air in the vehicle interior to be sucked through the suction hole 56 of the sensor connector 54 connected to the aspiration hose 60.

Accordingly, the intake sensor 52 installed in the sensor connector 54 of the sensor unit 50 senses the air in the vehicle interior that is sucked through the suction hole 56.

That is, the air passing through the evaporator 20 passes through the suction portion V of the earthpirator 61 at a high wind speed. Thereby, a negative pressure is formed around the suction portion (V) of the earthpirator (61), and this negative pressure is transmitted to the suction hole of the sensor connector (54) by the air discharge hose 56).

When the air in the vehicle interior is sucked through the suction hole 56 of the sensor connector 54, the incase sensor 52 senses the temperature of the air sucked into the suction hole 56.

The sensor unit 50 is connected to a piercing hose 60 of a corrugated pipe type in order to suck air in the room through the suction hole 56.

As described above, the earthpirator 61 provided in the air conditioning case 35 is directly installed in the earth-mover coupling portion 76 formed on one side of the air conditioning case 35.

The above-described earthquator coupling portion 76 is formed in both the manual and the electric air-conditioning case 35. [ In the air conditioning case 35 used for manual cooking, as shown in Fig. 3, since the earth filler 61 is not provided, the engagement hole is clogged with the clog plate 78.

On the other hand, in the air conditioning case 35 used for fully automatic operation, as shown in Fig. 4, a coupling hole 80 in which the closure plate 78 is not formed is formed in the earth fitter coupling portion 76. [

The above-described engagement hole 80 is formed by a core mold (not shown) manufactured separately from a mold for manufacturing the air conditioning casing 35. [

That is, in the air-conditioning case 35 of the electronic type, a separate core mold is required in order to form the engaging hole 80 for mounting the earth filler 61. [ Such a core mold has a problem of raising the manufacturing cost of the air conditioning case.

In addition, since the engaging hole 80 formed by the core metal is merely pierced, the inflow speed of the blowing air is low and the negative pressure can not be properly formed in the earthpirator 61.

Accordingly, there is a problem that the air in the passenger compartment is not properly sucked through the suction hole of the sensor unit 50 connected to the evacuation hose 60.

As described above, if the air in the passenger compartment is not sucked properly, the inca sensor can not accurately measure the temperature of the air. As a result, the test of the performance characteristics of the fully automatic temperature control device is repeated, thereby increasing the test cost.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the problems of the prior art described above, and it is an object of the present invention to make it possible to easily form a guide plate and an engaging hole by hitting a clogged plate blocking an earth-

Another object of the present invention is to increase the suction flow rate of air by forming a guide plate formed by incision of a clogged plate to be formed at the entrance side of the engagement hole.

It is still another object of the present invention to increase the flow rate of air passing through the engagement hole by the guide plate, thereby facilitating the performance test of the electronic temperature control device.

It is still another object of the present invention to provide an incision guide groove in a clog plate of an earthquator coupling portion to facilitate incision by impact.

Yet another object of the present invention is to improve the suction flow rate by allowing the guide plate attached after the incision of the clogged plate to function as a baffle at the entrance of the engagement hole.

It is a further object of the present invention to enable the guide plate to be easily pushed into the coupling hole by using an earth plate coupled to the coupling hole.

In order to achieve the above object, the present invention provides a vehicle air conditioning system comprising an air conditioning case for sucking in / outside air to supply air conditioned by a blower, an evaporator and a heater core to a room of a vehicle, The air conditioner according to any one of claims 1 to 3, wherein the air conditioner case includes a flange portion formed in the air conditioner case and an outer surface formed on the inner circumferential surface of the flange portion, And a clogging plate for blocking the hole to be detached from the flange portion.

The clogging plate may include a dropout plate cut along the incision guide groove and separated from the dropout plate along the incision guide grooves so as to be attached to the inner circumferential surface of the flange during the hitting.

The guide plate of the above-mentioned clogging plate is characterized in that a connecting portion is formed on the inner circumferential surface of the flange portion so as to be easily bent.

The air conditioner further includes an insertion pipe inserted into the flange portion of the air conditioning case while pushing the guide plate into one side of the fastening flange fastened by the fastening means to the flange portion of the air conditioning case.

In addition, the incision guide groove is formed as a dashed line on the clogged plate so that the clogged plate can be cut in a predetermined shape by external pressure.

According to the present invention, there is an effect that the air conditioner case can be easily mounted by blowing the clogged plate of the earth-waterproofing unit engaging.

In addition, since the guide plate cut through the clogging of the clogging plate is formed at the entrance of the engagement hole, there is an effect that the intake flow rate of the air can be improved.

Further, since the core mold for forming the engaging hole in the earth emitter coupling portion is not required, there is an effect that the cost of developing the core mold and the production cost of the air conditioner case can be reduced.

Further, as the suction flow speed of the air is increased by the guide plate, the performance test of the automatic temperature control device can be completed quickly, and the test cost can be reduced.

Further, the guide plate is pushed into the engaging hole to be formed at the entrance, so that the baffle function can be performed.

As shown in Figs. 3 and 4, the air conditioning case 35 is provided at one side thereof with an earth-collector coupling portion 76. Fig. The above-described earthquator coupling portion 76 is formed in the air conditioning case 35 so as to serve both as a manual and an electromagnetic type.

3, in the air conditioner case 35 used for passive cooking, since the earthpirator 61 is not provided, the engagement hole 76 is formed in the closure plate 78 ).

As shown in Fig. 4, the air conditioner case 35 used for fully automatic operation is provided with a coupling hole 80 in which the closure plate 78 is not provided in the earth fitter coupling portion 76. [

The above-described engagement hole 80 is formed by a core mold (not shown) which is separate from the mold for manufacturing the air conditioning casing 35.

Since the general structure described above has been described in the related art, a duplicate description will be omitted.

Next, the feature of the air conditioner for a vehicle according to the present invention will be described in detail with reference to Fig.

5, the air conditioning apparatus according to the present invention sucks in / outside air to supply air conditioned by the blower 18, the evaporator 20, and the heater core 24 to the interior of the vehicle And the air conditioning case 35 is provided.

The air conditioning case 35 is provided with an earth resonator coupling portion 76 for mounting the earth mirror 61 on one side thereof.

The above-mentioned earthquator coupling portion 76 has a flange portion 82 protruding from the air conditioning case 35. The flange portion 82 protrudes within a range in which the earth filler 61 can be firmly mounted. The flange portion 82 is formed with a closure plate 78 for blocking the hole on the inner circumferential surface thereof.

The blocking plate 78 is formed to have a thickness that can be cut by external pressure. The closure plate 78 is formed with a cutout guide groove 84 in a dotted line so that the cutout is formed in a predetermined shape.

The closure plate 78 is provided with a dropout plate 86 which is cut along the cutout induction groove 84 and separated. The closure plate 78 also has a guide plate 88 attached to the inner circumferential surface of the flange portion 82 when striking. The guide plate 88 is detached from the dropout plate 86 cut along the cutout guide groove 84.

The guide plate 88 is inserted into the engaging hole 80 by an earth plate 61 coupled to the engaging hole 80.

A connecting portion 90 is formed in the guide plate 88 of the clogging plate 78 to facilitate insertion into the engaging hole 80 formed in the flange portion 82.

An insertion pipe 92 is formed on one side of the fastening flange 62 of the earth filler 61. The insertion tube 92 is inserted into the flange portion 82 while pushing the guide plate 88 into the engagement hole 80.

Hereinafter, the operation of the present invention as described above will be described.

First, in the case of the electromagnetic type specification in which the earth filler 61 is mounted, the cutoff plate 78 formed in the air conditioner coupling portion 76 of the air conditioning case 35 is struck to cut the incision guide groove 84 .

The closure plate 78 cut along the incision guide groove 84 is separated into a guide plate 88 and a dropout plate 86. Thus, although the guide plate 88 is attached to the flange portion 82 as it is, the fall-off plate 86 is separated and removed.

The flange portion 82 is formed with the guide plate 88 and the engaging hole 80 is exposed.

In this state, the earthpirator 61 is engaged with the earth-mover coupling portion 76 of the air-conditioning case 35. The insertion pipe 92 of the fastening flange 62 pushes the guide plate 88 into the engagement hole 80 when the above-described earth filler 61 is coupled to the flange portion 82. At this time, the guide plate 88 is easily folded by the connecting portion 90.

When the fastening flange 62 of the above-mentioned earth filler 61 is completely inserted into the flange portion 82, the guide plate 88 is firmly fixed to the inner peripheral surface of the flange portion 82 by the insertion tube 92 It becomes a supported state. Such a guide plate 88 can guide air without collapsing even under the pressure of air to be blown.

As described above, when air is blown into the air conditioner case 35 equipped with the earthpirator 61, the blowing air moves through the internal passage and passes through the evaporator 20. The air that has passed through the evaporator 20 passes through the front of the engagement hole 80 of the earth coupling portion 76 formed at one side of the air conditioning case 35.

The blowing air strikes the guide plate 88 protruding from the inlet of the engaging hole 80, so that the flow velocity of the air is increased. At this time, the blowing air whose flow rate is increased rapidly passes through the earthpirator 61 coupled to the guide passage engagement hole 80 of the guide plate 88, and then is discharged to the discharge port 72.

The negative pressure formed in the earthpirator 61 when the blowing air passes through the earthpirator 61 is transmitted to the inside of the vehicle interior through the aspiration hose 60 connected to the suction pipe 74 of the earthpirator 61, So that the air in the air is sucked. When the air in the passenger compartment is sucked in at a high speed through the sensor unit 50 connected to the abovementioned hysteresis hose 60, the incase sensor 52 installed in the sensor unit 50 senses the air temperature.

When the air in the room is sucked through the sensor unit 50, the incase sensor 52 senses the temperature of the room and provides it to the control unit. Also, the performance characteristics test of the fully automatic temperature control device can be easily performed.

According to the present invention, since the guide plate and the engagement hole are formed by striking the clogged plate of the earth coupling unit formed in the air conditioning case that also serves as a manual and an electromagnetic type, the process of forming the engagement hole using the core mold can be omitted, The guide plate pushed into the fitting hole during the installation of the air conditioner guides the suction of the air so that the suction flow rate of the blowing air is increased to speed up the performance test of the automatic temperature control device. Can be widely used.
