The present invention relates to a left and right independent air conditioner, and more particularly, to a left and right independent air conditioner having a door assembly that can be used for left and right independent control methods as well as left and right common control methods. will be.

A typical automotive air conditioner is a device for cooling or heating an interior of an automobile. The air supplied from a blower unit includes an evaporator through which refrigerant flows and a heater core through which coolant of an automobile engine flows. By selectively passing through) is supplied to the interior of the vehicle through a duct connected to each part of the interior of the vehicle to cool or heat the interior of the vehicle.

In recent years, a lot of independent air conditioning units are applied to high-end vehicles, which divides the vehicle's interior into two, so that each part (for example, the driver's seat and the passenger's seat) can be independently operated. to be.

1 shows an example of left and right independent air conditioners.

Referring to the drawings, the left and right independent air conditioners 100 include a case 111 having an air passage therein, and two air passages 113 and a second air passage 114. A partition 112 partitioned into a furnace, an evaporator 115 formed upstream of the air passage, a heater core 116 provided downstream of the air passage, and a blower 117 provided at the air inlet 118 of the case 111. It is provided. In addition, the air inlet of the case 111 is provided with an outside air / betting switch door 118a to selectively enter the outside and the bet, and at least one mode door 119a is provided at the air outlet 119 of the case 111. It is installed downstream of the first and second air passages 113 and 114, and two temperature control doors 116a are installed on the first and second air passages 113 and 114 directly upstream of the heater core 116. To control the amount of air entering the

Inlet by the heater core 116, and then selectively heated by the heater core 116, and then supplied to the left or right of the interior of the vehicle through the air outlet 119 formed downstream of each air passage (113, 114), It will partially cool or heat the room.

By the way, in the above left and right independent air conditioner, either the mode door or the temperature control door may be the left and right common control system instead of the left and right independent control system. For example, if the mode door is a common left and right control method, it is possible to use a large door of a size that can cover both the left and right opening and closing, or to manufacture the left and right doors separately to combine them.

Doors manufactured to such a large size are easily deformed by heat generated from the engine, and air leaks are frequently generated by the deformation of the door. In addition, a large driving source or force is required to operate a large size door, and the air flowing through each passage is interrupted by the door, thereby increasing the resistance to flow. In addition, there is a problem in that the manufacturing cost is increased when the doors having different sizes are manufactured to be used separately for each of the left and right independent control methods and the left and right common control methods.                         

The left and right doors are separately manufactured and used for the left and right common control systems, and the door assembly disclosed in Japanese Patent Application Laid-open No. Hei 6-816 is shown in FIGS. 2 and 3.

Doors 2, 3, which are supported by bearings 4 formed in the partition wall 1, and the shaft members 5 which engage the doors 2, 3. And 6). The shaft members 5, 6 engage the doors 2, 3 by having a shape in which part of the planar portion is cut off at the ends 5a, 6a having a semicircular cross section.

The door assembly has a structure in which the respective end shapes correspond to each other when the shaft members 5 and 6 of the left and right doors 2 and 3 are coupled. In this case, the shaft members 5 and 6 are not stably bound. There is a problem that is rotated away from the axis of.

The present invention is to solve the problems as described above, by separately manufacturing the left and right doors can be used in the left and right independent control method, at least one of the left and right doors is inverted common left and right control It is an object of the present invention to provide a left and right independent air conditioner having a door assembly that can be used in a manner.

Left and right independent air conditioning apparatus of the present invention for achieving the above object is a case formed with an air passage therein; A partition wall partitioning the air passage into two first air passages and a second air passage; An evaporator and a heater core installed in the air passage part; First and second doors disposed in the case coaxially with each of the first air passage and the second air passage to control the flow of air; And coupling means for combining the first and second doors to enable left and right common control.

Here, the coupling means, the first shaft is formed on one side of the first door and has a projection having a non-circular cross-section at one end, and formed on one side of the second door and the projection of the first shaft to be inserted And a second shaft member having a groove formed at one end thereof.

In addition, the first and second doors coupled by the coupling means are separated and one of them is installed inverted, so that left and right independent control is possible.

Hereinafter, with reference to the accompanying drawings will be described the present invention according to a preferred embodiment.

A first door 10 provided; A second door having a second shaft member 22 provided on the same axis of the first shaft member 12 and a second door plate member 21 formed on one side of the second shaft member 22 ( 20). A partition wall is positioned between the first door 10 and the second door 20 to distinguish a space in which the first door 10 and the second door 20 are rotated.

At one end 12a of the first shaft member 12, a first protrusion 13 having a semicircular cross section is formed. The first protrusion 13 is not limited to a semi-circular shape, and various kinds are possible as long as it is non-circular. In addition, the other end portion 12b of the first shaft member 12 corresponds to the first protrusion 13, and the depth thereof is larger than the length of the first protrusion 13 by the thickness of the partition wall 30. The first groove 14 is formed.

A second protrusion 23 having the same size and shape as the first protrusion 13 is formed at one end 22a of the second shaft member 22. In addition, a second groove 24 having the same size and shape as the first groove 14 is formed in the other end portion 22b of the second shaft member 22. The second protrusion 23 of the second door is coupled to the first groove 14 of the first door. Since the depth of the first groove 14 and the length of the second protrusion are different from each other by the thickness of the partition wall 30, the partition wall is formed in the coupling portion to which the first groove 14 and the second protrusion are coupled. The gap A by the thickness of 30) arises.

The partition 30 has a plate-like bearing 32 on both sides of the partition 30 along the circumferential surface of the through hole 31 formed in the partition 30. The other end portion 12b of the first shaft member and one end portion 22a of the second shaft member are coupled to the inner wall 32a of the bearing supported on the partition wall 30. The first door 10 and the second door 20 are simultaneously supported by the bearing 32.

In addition, the left and right fixing jaw 33 is installed on the inner wall 32a of the bearing, along the circumferential surface of the central portion of the inner wall, and the left and right fixing jaw 33 is fitted into the gap A so that the first door 10 is provided. And the second door 20 are supported by the bearing 32 in a balanced manner without being biased left and right.

Accordingly, the same reference numerals as in the above-described drawings indicate the same components having the same function, and thus will not be described in detail because they are substantially the same as described above.

The other end part 12b in which the first groove 14 of the first shaft member 12 of the first door is formed is the other end part in which the second groove 24 of the second shaft member 22 of the second door is formed. It is preferable that it is supported so as to be supported by the inner wall 32a of the bearing supported along the circumferential surface of the through hole 31 formed in the partition wall 30 together with the 22b.

Meanwhile, the first door 10 and the second door 20 are simultaneously supported by the bearing 32 formed on the partition wall 30. On the inner wall 32a of the bearing, left and right fixed jaws 33 are installed along the circumferential surface of the central portion of the inner wall, and the left and right fixed jaws 33 are fitted into the gap A so that the first door 10 is provided. And the second door 20 are supported by the bearing 32 in a balanced manner without being biased left and right.

Therefore, unlike the door assembly according to the embodiment to securely engage the first door, the second door (10, 20) to be interlocked, the door assembly for the air conditioner according to the present embodiment is the second door (20) ) Is reversed so that the first and second doors 10 and 20 are not coupled to each other and move independently, thereby allowing left and right independent control.

As described above, the door assembly according to the present invention forms a protrusion on one end of the shaft member of the left and right doors and forms a groove on the other end so that the left and right common control methods are much more powerful and easy. By combining the doors, there is an advantage that the left and right doors can be rotated without misalignment on the same axis.

In addition, by inverting any one of the left and right doors so that the left and right independent control methods can be used, common left and right control methods and left and right independent control methods can be used, thereby reducing manufacturing costs. There is an advantage that it can.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Could be. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
