Recently, so-called left and right independent air conditioners have been applied, in which air is supplied to the driver's seat and the passenger's seat at different temperatures according to the needs of the passengers, so that individual cooling and heating is performed.

As an example of the left and right independent air conditioner for a vehicle, Korean Patent Publication No. 10-2010-0022751, which is filed by the present applicant, will be described with reference to FIG. 1. An air inlet 27 is formed and a plurality of air outlets 28 are formed on the other side, and an air conditioning case 20 having air passages 26a and 26b formed therein, and the air passages 26a and 26b. Evaporator (2) and heater core (3), which are installed at regular intervals in sequence, and downstream air passages (26a, 26b) of the evaporator (2) to left and right air passages (26a, 26b). The partition wall 30 which divides | segments and the blower 10 provided in the air inlet 27 side of the said air conditioning case 20 are comprised.

Here, the air conditioning case 20 is divided into left and right cases with respect to the separation wall 30 and assembled with each other.

In addition, between the evaporator 2 and the heater core 3, a temperature control door 25 for temperature control is installed on the left and right air passages 26a and 26b, respectively. Each of the air outlets 28 of the furnaces 26a and 26b is provided with a plurality of mode doors 24 to control various openings of the air outlets 28, such as vent mode, bi-level mode, and floor mode. , Mix mode, defrost mode).

In addition, the blower 10 is formed inside and outside air inlet (not shown) that is opened and closed by the internal and external air conversion door (not shown) to selectively enter the internal and external air on the upper side, the inside, A blowing fan 15 for blowing air introduced through the outside air inlet to the air conditioning case 20 is installed.

In addition, the air flowed through the blower 10 is separated into the left and right air passages 26a and 26b of the air conditioning case 20 and supplied to the upstream side air passages of the evaporator 2. An auxiliary separating wall 31 is formed to partition to the right, and the air volume adjusting door 40 for controlling the air volume distributed to the left and right of the auxiliary separating wall 31 is installed at the side of the auxiliary separating wall 31.

The conventional left and right independent air conditioning apparatus 1 having the above configuration is cooled while the internal air or the outside air introduced into the air conditioning case 20 by the blower 10 passes through the evaporator 2 ( When the air conditioner is turned on), this air is introduced into the left and right air passages 26a and 26b by the separating wall 30 and then selectively heated by the heater core 3, and then each air passage 26a. It is supplied to the driver's seat or passenger seat side of the vehicle interior through each air discharge port 28 formed downstream of 26b to independently cool and heat the driver's seat or passenger seat space of the vehicle interior.

In addition, control of the temperature control door 25 installed on the left and right air passages 26a and 26b of the air conditioning case 20 and the air volume control door 40 installed at the front side of the evaporator 2, respectively. Through this, it is possible to independently control the temperature and the amount of air discharged to the driver's seat and the passenger seat.

That is, if the air volume control door 40 is adjusted, for example, the driver's seat can supply the seven-stage air volume, and the passenger seat can supply the first-stage air volume.

However, in the left and right independent air conditioning apparatus 1 for controlling the left and right air volume separately as in the conventional art, the left and right condensed water generated in the evaporator 2 is properly removed regardless of the left and right air volume distribution. Should be, but

In the case of separately controlling the left and right air volume separately through the air volume control door 40, the portion of the evaporator 2 located on the air passage side having a large air volume has a large amount of air, and condensed water is easily removed, while the air flow side has a small air volume. The portion of the evaporator 2 located in the air volume is small so that the condensate is not removed and remains on the lower side of the evaporator 2.

As a result, in the evaporator 2 portion located on the side of the air passage where the air volume is small, there is a problem that the residual amount of condensed water is large and the bacteria grow, as well as the smell, and the antimicrobial coating life of the evaporator 2 decreases.

An object of the present invention for solving the above problems is to form a communication portion for communicating the left and right air passages in the auxiliary separation wall partitioning the upstream side air passages of the evaporator to the left and right, the air passage having a relatively large air volume By partially supplying the side air to the air passage side where the air volume is small, it is possible to remove condensed water remaining in the evaporator where the air volume is small, thereby preventing condensate remaining in the evaporator to improve sterilization and odor, and improve the surface of the evaporator. It is to provide a left and right independent air conditioner for vehicles that can extend the antimicrobial coating life.

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

As shown, the left and right independent air conditioner for a vehicle 100 according to the present invention, the air inlet 111 is formed on one side and the defrost vent 121, the face vent 122, the floor vent 123 on the other side A plurality of air discharge holes 120 formed of the air inlet and the air inlet 111 and the air outlet 120 is formed so as to communicate with the air inlet 111 and the inside, and sequentially on the air passage An evaporator 101 and a heater core 102 installed at a predetermined interval, and a separation wall 105 for dividing the air passages downstream of the evaporator 101 into left and right air passages 106a and 106b; The air inlet 111 of the air conditioning case 110 is installed so that the outlet 16 is connected to include a blower 10 for blowing air into the air conditioning case 110.

Here, the air conditioning case 110 is formed by assembling left and right cases (110a) and (110b) divided from each other.

In addition, a temperature control door 130 for temperature control is installed between the evaporator 101 and the heater core 102. The temperature control door 130 is the left and right air passages 106a and 106b. Respectively installed on the air passage to bypass the heater core 102 and to adjust the opening degree of the air passage passing through the heater core 102.

In addition, after passing through the evaporator 101, each of the defrost vent 121 to selectively distribute the coarse air through the heater core 102 to each duct (not shown) in communication with a specific position in the vehicle interior. The face vent 122 and the floor vent 123 are provided with a plurality of mode doors 124 to perform various air discharge modes.

The evaporator 101, the upper and lower tanks are formed in communication with the upper and lower portions of the tube 101a spaced apart from each other by a predetermined interval and arranged in communication with the plurality of tubes 101a. 101b and 101c, heat dissipation fins 101d interposed between the plurality of tubes 101a, and upper and lower tanks 101b and 101c or one tank side, and are provided with inlet and outlet ports for introducing and discharging refrigerant. It consists of the pipe 101e.

On the other hand, the blower 10 is formed inside and outside air inlet (not shown) and the outside air inlet 11 which is opened and closed by the internal and external air conversion door (not shown) so as to selectively flow into the upper side, the inside The blower fan 15 is installed to blow air introduced through the internal and external air inlets to the air conditioning case 110.

The air inlet 111 of the air conditioning case 110 has a predetermined length from the side of the air conditioning case 110 to the outlet 16 of the blower 10 so as to be connected to the outlet 16 of the blower 10. It extends to have a straight section.

That is, as shown in the drawing, the air inlet 111 is formed to be perpendicular to the left and right air passages 106a and 106b partitioned by the partition wall 105 in the air conditioning case 110. At this time, the air inlet 111 is formed in parallel with the evaporator 101.

Then, the evaporator 101 so that the air blown through the blower 10 is separated and supplied to the left and right air passages 106a and 106b in the air conditioning case 110 partitioned by the separation wall 105. An auxiliary separation wall 160 is formed to partition the upstream side air passages 161 and 162 to the left and the right.

The auxiliary dividing wall 160 is formed between the air inlet 111 and the evaporator 101. At this time, an end (tip) of the auxiliary dividing wall 160 adjacent to the air inlet 101 will be described later. Adjacent to the rotating shaft 151 of the air volume control door 150, the end (rear end) of the auxiliary separation wall 160 adjacent to the evaporator 101 is bent to the evaporator 101 side to the evaporator 101 Adjacent to the front face.

Here, the end of the auxiliary separation wall 160 adjacent to the front surface of the evaporator 101 is located on the same line as the separation wall 105 installed inside the air conditioning case 110.

Therefore, the air distributed to the left and right through the air volume control door 150 to be described later is completely separated to the left and right through the auxiliary separation wall 160 formed between the air volume control door 150 and the evaporator 101, the air conditioning. Since the left and right air passages 106a and 106b in the case 110 flow, it is possible to implement a perfect left and right air volume control system.

In addition, the air volume control door 150 is installed at the sub dividing wall 160 to adjust the air volume distributed to the left and right of the sub dividing wall 160. In this case, the air volume adjusting door 150 is the air. It is installed adjacent to the end side of the auxiliary separation wall 160 adjacent to the inlet 111.

In other words, the air volume control door 150 has a uniform cross-sectional area of the air passage is preferably installed in the air inlet 111 is relatively uniform air flow.

That is, the internal passage of the air inlet 111 has a uniform cross-sectional area so that the air flow is relatively uniform compared to other parts of the air conditioning case 110, and thus there is no change in the air volume, thereby controlling the air volume inside the air inlet 111. The door 150 is to be installed.

In addition, although the air volume control door 150 may be installed as a single, two may be installed in the vertical direction, as shown in FIG.

At this time, a sealing wall 140 is formed inside the air inlet 111, and the sealing wall 140 is formed between the two air volume control doors 150 to provide a space between the air volume control doors 150. Will be partitioned.

Due to this, the two air volume control doors 150 are installed to operate independently in the upper and lower passages of the air inlet 111 partitioned by the sealing wall 140.

The sealing wall 140 prevents leakage of air between the upper and lower passages when the two air volume control doors 150 independently adjust the upper and lower passages of the air inlet 111. do.

On the other hand, the two air volume control doors 150 are operated independently through an actuator (not shown) installed on the upper and lower sides of the air inlet 111, respectively.

The air volume control door 150 is formed on the rotary shaft 151 perpendicular to the inner center of the air inlet 111, and formed on the side of the rotary shaft 151 toward the outlet 16 of the blower 10. It is formed of a plate 152 extending and formed to distribute the air blown to the left and right air passages (161, 162) of the auxiliary separation wall (160).

As such, two air volume control doors 150 installed on the upper and lower sides of the air inlet 111 partitioned through the sealing wall 140 are operated independently of the left and right passages of the auxiliary separation wall 160. If the air flow rate is adjusted to 161 and 162, one or more air volume control doors 150 may adjust the left and right air volume more finely than the left and right air volumes.

Condensed water is generated in the evaporator 101 regardless of the left and right air volume distribution in the air conditioning case 110. Although easily removed, the amount of air is small in the portion of the evaporator 101 located on the side of the air passage where the air volume is small, so that condensed water remains.

Since the condensed water remaining in the evaporator 101 flows in the gravity direction, the condensed water remains mainly on the upper surface side of the lower tank 101c of the evaporator 101.

Therefore, a communication portion 165 is formed in the auxiliary separation wall 160 so as to communicate the left and right air passages 161 and 162 of the auxiliary separation wall 160, and thus, The right air passages 161 and 162 partially supply the air passage side air having a larger air volume to the air passage side with a smaller air volume to remove condensed water remaining in the evaporator 101.

That is, when the communication portion 165 is formed in the auxiliary separation wall 160, the air flow distribution door 150 through the air distribution to the left and right air passages (161, 162) of the auxiliary separation wall 160, Due to the difference in static pressure generated by the air passage side air having a large amount of air flows to the air passage side with a small amount of air through the communication unit 165.

The communication part 165 is formed through the end side of the auxiliary separation wall 160 adjacent to the evaporator 101.

At this time, the communication unit 165 is preferably formed at the lower end side of the auxiliary separation wall 160 so that air is supplied to the lower side of the evaporator 101 in which condensed water remains.

In addition, the communicating portion 165 is formed in a square shape on the end side of the auxiliary separation wall 160, the lower end of the communicating portion 165 is the same as the upper surface of the lower tank 101c of the evaporator 101. It is formed to be on the line or the upper side.

That is, since condensed water remains mainly on the upper surface side of the lower tank 101c of the evaporator 101, blowing air to the upper surface of the lower tank 101c of the evaporator 101 is effective for removing condensed water, and thus, the communication. It is preferable to form the lower end of the unit 165 to be in line with the upper surface of the lower tank 101c of the evaporator 101 or to be located above the upper surface of the lower tank 101c of the evaporator 101.

In addition, one side of the communication unit 165, the guide 166 is extended to guide the air passing through the communication unit 165 to the evaporator 101 side smoothly.

In this case, the guide 166 is formed on one side surface of the communication unit 165 far from the evaporator 101.

In other words, the guide 166 is formed on one vertical surface of the communication unit 165 located at the most upstream side in the air flow direction in the rectangular communication unit 165.

Here, two guides 166 are formed in the height direction, and are formed to be inclined with respect to the auxiliary separation wall 160 while spreading toward the left and right air passages 161 and 162 of the auxiliary separation wall 160, respectively.

That is, one guide 166 is formed in the lower portion in the communication portion 165 while being inclined to the left air passage 161, and the other guide 166 is formed in the upper portion in the communication portion 165 and the right reservoir It is formed to be inclined to the furnace 162.

Therefore, when the air passage side air having a large amount of air flows partially through the communicating portion 165 toward the air passage side with a small amount of air, it is smoothly guided to the lower side of the evaporator 101 by the guide 166 to provide an evaporator ( The condensate remaining in the lower portion of 101) is efficiently removed.

Meanwhile, a drain port 112 is disposed in one region of the left and right air passages 106a and 106b of the air conditioning case 110 to discharge the condensed water generated from the evaporator 101, and the auxiliary separation wall ( Air may flow to the air passage side where the drain port 112 is disposed through the communication unit 165 formed at 160. Therefore, since the air flows to the drain port 112 through the communication unit 165, the condensed water generated in the evaporator 101 is smoothly discharged to the drain port 112.

Hereinafter, the air flow process of the left and right independent air conditioning apparatus for a vehicle according to the present invention will be described. Here, only the cooling mode will be described as a representative mode.

First, air blown through the outlet 16 of the blower 10 by the operation of the blower 10 is introduced into the air inlet 111.

The air flowing into the air inlet 111 is separated into the upper and lower portions of the air inlet 111 by the sealing plate 140, and the air is provided at two upper and lower sides of the sealing plate 140. The left and right air volume is controlled by the air volume control door 150, the air in which the left and right air volume is adjusted is completely separated by the auxiliary separation wall 160 to the left and right sides, the evaporator in the air conditioning case 110 ( 101).

The air passing through the evaporator 101 is changed to cold air in the process of passing through the evaporator 101, the cold air heat exchanged in the evaporator 101 is in the internal partition wall 105 of the air conditioning case 110. This is distributed to the left air passage 106a and the right air passage 106b.

Subsequently, the coldly changed air passing through the evaporator 101 bypasses the heater core 102 by the temperature control door 130, and then vent 121 opened by the mode door 124. By discharging into the vehicle interior through the 122 and 123, the driver's seat and the passenger seat in the vehicle compartment are cooled.

Of course, in the process, the two air volume control doors 150 installed in the air inlet 111 to be operable separately, and the temperature control door 130 installed in the left and right of the separation wall 105 to be operated separately and When the mode door 124 is adjusted independently of each other, the driver's seat and the passenger seat can be independently controlled by the passenger's desired air volume, temperature, and air discharge mode.

And, for example, in the case of setting the driver's seat to the seven-stage air volume and the front passenger's seat to the first stage air volume as shown in Figure 6 by controlling the air volume control door 150, the air volume control door 150 is the auxiliary separation It rotates toward the right air passage 162 (passenger seat side) of the wall 160 to distribute the seven stage air volume to the left air passage 161 (driver's seat side) and the first stage air volume to the right air passage 162.

Subsequently, a large amount of air flows toward the left air passage 161 side of the auxiliary separation wall 160 in which the seven-stage air volume is distributed, and condensate generated in the left portion of the evaporator 101 is easily removed, and the first-stage air volume is distributed. The air volume 162 of the separation wall 160 is less than the air volume, so that the removal of condensate generated at the right side of the evaporator 101 may be insufficient. However, in the present invention, the air passage 161 having the large air volume flows. Part of the air is partially supplied to the right air passage 162 having a small air volume through the communication unit 165 to smoothly remove the condensed water remaining in the lower portion of the evaporator 101.

Therefore, it is possible to prevent the remaining condensate in the evaporator 101 to improve the disinfection and odor, and to extend the antimicrobial coating life of the evaporator 101 surface.

On the other hand, the above has been described only for the cooling mode, in addition to this can be carried out a variety of air conditioning modes, including the heating mode, such a air conditioning mode is known in the detailed description is omitted here.
