At this time, as shown in FIG. 6A , the air passage 110 has a scroll shape formed to surround the periphery of the blower 120 , and the plurality of air outlets is a circumference of the air passage 110 . It may be formed spaced apart along the direction. This will be described in detail below.

The blower 120 is coupled to a motor 122 coupled/fixed to one side of the air conditioning case 100 through a flange 126 , and a rotation shaft of the motor 122 , and rotates on the air passage 110 . It is composed of a wheel 124 that forcibly blows air while. At this time, inside the air conditioning case 100 on the upstream side of the wheel 124 , there is a bell mouth for guiding the air sucked through the air inlet 400 to the center of the wheel 124 . can be formed.

Accordingly, when the air conditioner of the present invention is mounted on a vehicle, the rotation shaft of the motor 122 is installed parallel to the ground, so that the motor can be immediately separated during servicing, thereby improving serviceability.

A heat exchanger for heating is installed on the downstream side of the blower 120, and a heat exchanger for cooling is installed on the upstream side of the blower 120. In this embodiment, the heat exchanger for heating is detachably coupled to the air conditioning case 100. It is provided in a heat exchanger module for heating, and the heat exchanger for cooling may be provided in a heat exchanger module for cooling that is detachably coupled to the air conditioning case 100 .

However, the present invention is not limited thereto, and the cooling heat exchanger is integrally fixed to the inside of the air conditioning case, but only the heating heat exchanger may be installed in a separate module, and the heating heat exchanger is integrally fixed inside the air conditioning case However, only the heat exchanger for cooling may be installed in a separate module.

Hereinafter, the heat exchanger for heating is the heater core 220 , and the heat exchanger for cooling is the evaporator 320 , respectively, which are provided in the heater core module 200 and the evaporator module 300 . However, the present invention is not limited thereto, and any type of heat exchanger for heating and a heat exchanger for cooling may be used as long as heat exchange is performed for heating and cooling, respectively.

Specifically, as shown in FIGS. 5 and 6 , in the heater core module 200 , the heater core 220 is mounted on the air passage 110 on the downstream side of the blower 120 based on the vehicle mounting direction. It can be installed horizontally and detachably coupled to the downstream side of the air conditioning case 100 so that the heat exchange surface (the surface through which air passes) can be installed parallel to the rotation axis of the motor 122 of the blower 120. .

That is, the heater core module 200 may be detachably coupled to the side surface of the air conditioning case 100 along the circumferential direction of the blower 120 parallel to the rotation axis of the blower 120 .

In this case, the heater core 220 may be installed completely horizontally, or may be installed at an angle as shown in the drawing to be inclined.

In addition, the heater core module 200 may be coupled to the air conditioning case 100 with a bolt.

Accordingly, when a redesign of the heater core is required to change the heating performance, the design can be easily changed, and the design cost and development time can be reduced. For example, in a warm country, since the capacity of the heater core does not need to be large, in order to redesign the heater core to be small, the heater core module can be removed and only the heater core can be easily replaced.

The heater core module 200 includes an inlet passage 240 for introducing air from the inside of the air conditioning case 100 , specifically, an air passage 110 formed inside the air conditioning case 100 , and the heater. It may include a discharge passage 260 for discharging the air that has passed through the core 220 into the air conditioning case 100 , specifically, into the air passage 110 .

Also, in response to this, the air conditioning case 100 has a communication hole for communicating the inlet passage 240 and the discharge passage 260 of the heater core module 200 and the air passage 110 of the air conditioning case, respectively. provided

Specifically, a first communication hole 112 for communicating the inlet passage 240 and the air passage 110 and a second communication hole for communicating the discharge passage 260 and the air passage 110 ( 114), and accordingly, the air flowing in the air passage 110 may selectively pass through the heater core 220 by the temp door 170 to exchange heat, as will be described later.

In addition, as shown in FIGS. 4 and 5 , the evaporator module 300 is installed vertically based on the direction when the evaporator 320 is mounted on the air passage 110 on the upstream side of the blower 120 . However, so that the heat exchange surface (the surface through which air passes) can be installed perpendicularly to the rotation axis of the motor 122 of the blower 120, that is, to face the blower 120, the air conditioning case 100 facing each other It can be detachably coupled to the front or back.

In this case, the evaporator module 300 may be bolted to the air conditioning case 100 .

In addition, the air inlet 400 may be coupled to the evaporator module 300 , and may be coupled to one side of the evaporator module 300 coupled to the air conditioning case 100 and a side opposite to the side coupled to the air conditioning case 100 .

Accordingly, the evaporator module 300 is coupled in communication with the suction port of the blower 120 so that the air introduced through the air inlet 400 can flow to the blower 120 .

The air inlet 400 includes an outdoor air inlet 420 through which outside air is introduced and a bet inlet 440 through which the bet is introduced, and inside the air inlet 400 , internal and external air inlets 420 and 440 are selectively selected. The inside and outside air switching door is rotatably installed so that it can be opened and closed with The internal and external air switching door may be formed of various types of doors, such as a dome-type door, and may be operated by an actuator and a cam (not shown) installed on the outside of the air conditioning case 100 .

Here, a filter 360 for removing impurities from flowing air may be installed on the upstream side of the evaporator 320 , that is, between the evaporator 320 and the air inlet 400 .

Accordingly, foreign substances introduced from the outside through the air inlet 400 can be filtered by the filter 360, so that foreign substances can be prevented from flowing into the blower 120 through the evaporator 320. have.

In addition, the evaporator module 300 may include a joint flange 340 for detachably connecting the evaporator 320 and a refrigerant pipe having one end connected to a dash panel of the vehicle, respectively, in the middle. .

Accordingly, when replacing and cleaning the evaporator, the In Panel is removed by loosening the joint flange and separating only a part of the pipe connected to the evaporator side without separating all the refrigerant pipes connected at one end to the evaporator and the dash panel, respectively. Since the evaporator can be easily separated without having to

Moreover, noise is generated in the process of sucking/blowing air during operation (rotation) of the wheel 124 of the blower 120. In the present invention, the motor 122 is located in both directions of the wheel 124, respectively. As the flange 126 and the evaporator 320 are installed, noise generated during operation of the wheel 124 is blocked without being exposed to the outside, thereby reducing noise.

Next, with reference to FIGS. 6A and 6B , the air sucked into the air conditioning case 100 through the air inlet 400 by the operation of the blower 120 specifically is the evaporator 320 and the heater core 220 . Let's take a look at the process of being cooled or heated by selectively passing through and then discharged through a plurality of air outlets.

As described above, the air passage 110 inside the air conditioning case 100 has a scroll shape formed to surround the periphery of the blower 120, and the evaporator 320 and the heater core 220 ), a flow path is formed so that the air that has selectively passed through swirls and flows to a plurality of air outlets.

At this time, the air passage 110 is expanded along the direction in which the air is sucked in and flows by the blower 120 as shown in FIGS. 3 and 7 , and is larger to the side farther from the air inlet 400 . expands asymmetrically.

Specifically, the air passage 110 has a larger area on the opposite side to the air inlet 400 than the area close to the air inlet 400 based on the center line A of the starting point of the air passage 110 .

Here, the center line A of the air passage 110 refers to a line drawn along the longitudinal direction of the air passage 110 based on the center at the starting point of the air passage 110 forming the scroll shape, and FIG. As shown in Fig., based on the center line (A) of the air passage (110), the distance from the center line (A) to the side closer to the air inlet port (400) is greater than the distance from the center line (A) to the air inlet ( 400) and the distance from the far side to the side can be formed to be larger.

Accordingly, when the evaporator 320 is positioned to face it from the upstream side of the blower 120 and the air selectively cooled while passing through the evaporator 320 is blown by the blower 120, the air Due to the high speed, in the air passage 110 , based on the center line A of the air passage 110 , the air is not concentrated in the far side from the air inlet 400 , and there is a difference in the air discharge amount on the left and right. can be prevented from doing

That is, as shown in FIG. 8 , the air introduced through the air inlet 400 is sucked into the blower 120 to prevent a phenomenon from flowing toward one side in the air passage 110 , and the air passage According to the scroll shape of (110), so as to be uniformly distributed and flowed as a whole.

At this time, a blower register 123 for adjusting the number of rotations of the blower 120 is installed in the air conditioning case 100, and the air in the case forming the air passage 110 asymmetrically expanded. It is preferable to be installed on the far side from the inlet 400 .

Specifically, as shown in FIG. 3 , the scroll case 102 forming the scroll-shaped air passage 110 of the air conditioning case 100 protrudes from the body, and the center line A of the air passage ), the scroll case 102 on the side farther than the side close to the air inlet 400 is expanded more to form an asymmetric shape, and the scroll case 102 with the blower resistor 123 expands more ) is installed on the protruding side of the

In addition, the plurality of air outlets are formed to be spaced apart along the circumferential direction of the air passage 110 , and are sequentially disposed along the air flow direction in the air passage 110 , a floor vent 130 , and a defrost vent 140 . ) and a face vent 160 . A duct connected to each outlet in the vehicle interior may be integrally formed in each of the vents, and cost reduction is possible through the vent-duct integrated structure.

At least one of the plurality of air outlets may be formed in the flow direction of the air flowing along the scroll shape of the air passage 110, and in particular, in this embodiment, the face vent 160 is installed in the air passage ( 110) is formed in the flow direction of the air flowing along the scroll shape.

Since the increase in the air volume of the air outlet can best feel the temperature control of the vehicle and the increase in the air volume of the occupant, it is effective to increase the air volume by forming the air outlet in the flow direction of the air.

Specifically, the face vent 160 is for discharging air toward the face of the occupant and may be formed to extend in the circumferential direction, that is, in a tangential direction, at the end of the air passage 110 , and thus air is discharged from the face vent. It may be discharged to the side of the air conditioning case 100 through 160 .

In addition, the defrost vent 140 is for discharging air toward the windshield of the vehicle, and is formed in the vertical direction of the blower 120 facing the heater core 220 in the middle of the air passage 110 . Accordingly, air may be discharged to the upper side of the air conditioning case 100 through the defrost vent 140 .

The floor vent 130 is for discharging air toward the feet of the occupant, and is formed in the middle of the air passage 110, specifically, near the end point of the heater core 220, and the defrost vent 140 and It may be formed in a vertical direction. However, it is not limited to being vertical and may be formed in a direction opposite to the face vent 160 , and accordingly, air may be discharged to the opposite side to the face vent 160 through the floor vent 130 .

Between the blower 120 and the heater core 220, the amount of air passing through the heater core 220 and the bypassing air among the air blown by the blower 120 is selectively adjusted to control the temperature of the air A temp door 170 for adjusting the .

The temp door 170 may be provided on the air conditioning case 100 or the heater core module 200, specifically, the inlet passage 240 of the heater core module 200 or the air conditioning case 100. It may be disposed on the first communication hole 112 of the.

In this embodiment, the temp door 170 is installed on the air conditioning case 100 so that the first communication hole 112 can be opened and closed, and accordingly, whether the first communication hole 112 is opened or closed. By adjusting , it is possible to selectively control whether the air in the air passage 110 flows into the heater core module 200 .

In addition, a plurality of mode doors 180 for opening and closing the floor vent 130 , the defrost vent 140 , and the face vent 160 , respectively, are installed inside the air conditioning case 100 . That is, each of the plurality of mode doors 180 has a first mode door 181 and a second mode door that opens and closes air directed to the floor vent 130 , defrost vent 140 , and face vent 160 , respectively. It consists of a mode door 182 and a third mode door 183 .

Each of the mode doors controls the amount of air discharged through each vent in various air conditioning modes such as defrost mode, face mode, floor mode, mix mode, and bi-level mode.

As described above, according to the vehicle air conditioner of the present invention, when the bet or outside air is sucked into the air conditioning case 100 through the air inlet 400 according to the operation of the blower 120, the filter 360 ), after the impurities are removed, it passes through the evaporator 320 and is selectively cooled according to cooling and heating modes.

In addition, the air selectively cooled while passing through the evaporator 320 is directed to the heater core 220 installed on the downstream side after passing through the blower 120. At this time, in the cooling mode, the temp door 170 is closed so that air flows by bypassing the heater core 220 , so it is not heated. In the heating mode, the temp door 170 is opened and air is heated while passing through the heater core 220 .

The air selectively heated by the heater core 220 is discharged into the vehicle interior after adjusting the amount of air discharged to each vent by the plurality of mode doors 180 to cool and heat the air.

In this way, the air sucked into the blower 120 moves through the scroll-shaped air passage 110 and is directly discharged through each of the air outlets connected thereto without changing the air flow path in the middle. At the discharge end of , that is, the scroll case 102 is asymmetrically formed along the direction in which air is discharged from the blower 120 and flows to each of the air outlets, so that the left and right winds of the air can be matched.

At this time, since the air passage 110 is formed in a scroll shape in the circumferential direction, it is possible to minimize the pressure resistance when the air flows, thereby reducing noise as well as increasing the air volume.

In addition, the evaporator is installed vertically on the upstream side of the blower and the heater core is installed horizontally on the downstream side of the blower. Size reduction is possible because the height and width direction of the case are reduced.
