First, the door 121, which is a feature of the present invention, is applicable to various air conditioning apparatuses such as a center mounting type, a semi-center type, and a three-piece type. Here, the semi-center type air conditioning apparatus 100 will be described as an example. do.

Briefly describing the semi-center type vehicle air conditioner 100, the air inlet 111 is formed on the inlet side and a plurality of air outlets are formed on the outlet side and the cold air passage (P1) and the hot air flow passage (on the inside passage) The air conditioner case P2 is formed, and the evaporator 101 and the heater core 102 installed on the flow path inside the air conditioner case 110 are configured.

In addition, the air inlet 111 of the air conditioning case 110 selectively introduces inside or outside air through an inside and outside air inlet (not shown) and an outside air inlet (not shown) that are opened and closed by an internal and outdoor air conversion door (not shown). A blower (not shown) for blowing air is installed.

A plurality of air outlets formed on the outlet side of the air conditioner case 110 include a defrost vent 112 for discharging air to the windshield of the vehicle and a face vent for discharging air toward the face of the occupant of the front seat (113) and floor vents (114, 115) for discharging air toward the foot of a passenger.

The floor vents 114 and 115 are separated into a front seat vent 114 for discharging air toward the front occupant's foot and a rear seat vent 115 for discharging air toward the rear occupant's foot. .

Meanwhile, a guide wall 116 is formed between the rear side hot air flow passage P2 of the heater core 102 and the floor vents 114 and 115 to be partitioned from each other.

In addition, a plurality of doors 121 are installed on the flow path in the air conditioning case 110, such that a specific flow path, that is, the cold air flow path P1, the hot air flow path P2, and the flow paths facing the vents 112 to 115, and the like. The opening degree is controlled.

The door 121 is provided between the evaporator 101 and the heater core 102 and the warm air passing through the cold air flow passage P1 and the heater core 102 bypassing the heater core 102. Mode installed on the upstream flow path of each vent to adjust the opening degree of the temperature control door 120a and the defrost vent 112, the face vent 113, the floor vents 114 and 115 to adjust the opening degree of the flow path (P2) It is divided into the door 120b.

Meanwhile, the temperature control door 120a and the mode door 120b are connected to a cam (not shown) or a lever (not shown) driven by an actuator (not shown) installed on an outer surface of the air conditioning case 110 to rotate. During operation, the cold and hot air flow passages P1 and P2 and the openings of the vents 112 to 115 are adjusted.

Hereinafter, the door 121 will be described in more detail.

The door 121 has a rotating shaft 123 rotatably installed at both inner walls of the air conditioning case 110 and a plate 122 formed at the rotating shaft 123 to adjust the opening degree of the flow path in the air conditioning case. And an edge portion is formed to protrude a predetermined length in an outward direction than an end portion of the plate 122 so that the protruding edge portion is closed in the air conditioner case when the passage is closed. It consists of a thin plate member 124 in contact with the 110.

That is, the size of the thin plate member 124 is formed larger than the plate 122, therefore, when the thin plate member 124 is coupled to the side of the plate 122, the edge of the thin plate member 124 The portion protrudes outward from the end of the plate 122.

At this time, the edge portion of the thin plate member 124 does not protrude to the end side of the plate 122 on which the rotating shaft 123 is spaced apart from the side of the plate 122 by a predetermined distance.

On the other hand, the plate 122 and the thin plate member 124 are each formed in a rectangular shape.

In addition, the thin plate member 124 may be a thin film made of polyethylene or polypropylene, but various materials may be used. In addition, the use of a thin film can be suppressed as the mold fungus inhabited as much as possible, and also because the friction coefficient is less close to the inner wall surface side of the air conditioning case 110, because it does not stick well when spaced apart to reduce noise. have.

In addition, when sealing is required on only one side of the doors 121 such as the mode door 120b, the thin plate member 124 is coupled to only one side of the plate 122, and the temperature control door 120a. When sealing is required on both sides as described above, the thin plate members 124 are separated and coupled to both sides of the plate 122, respectively.

In addition, the plate 122 is formed in the shape of a mesh (MESH) to reduce the weight of the door 121. That is, the plate 122 is formed in a mesh form (lattice form) that can be reduced as much as possible because only the skeleton for coupling the thin plate member 124.

At this time, even if the plate 122 is formed in a mesh shape, since the side surface of the plate 122 is covered by the thin plate member 124, air does not pass through the mesh plate 122.

In addition, as a method for coupling the thin plate member 124 to the side of the plate 122, a plurality of hooks 125 having a locking step 125a on the side of the plate 122 protrudes and is formed In the thin plate member 124, a plurality of coupling holes 124a are formed to be fitted to the hook 125.

In addition, the coupling hole 124a of the thin plate member 124 to be easily coupled to the hook 125 and at the same time after the incision, respectively, both sides of the hook so as to be caught on the locking step (125a) of the hook 125 It is provided with a locking portion 124b formed by.

On the other hand, when the coupling hole 124a of the thin plate member 124 is coupled to the hook 125 of the plate 122, the end of the locking portion 124b is the locking step 125a of the hook 125 ) The inclined surface 125b is formed at the lower end of the hook 125 so as to be in close contact with the lower side.

In addition, another method for coupling the thin plate member 124 to the side of the plate 122 is to adhere the thin plate member 124 to the side of the plate 122 as shown in FIG. Of course, an adhesive may be used and the method of fusion may be used.

In addition, the plate 122 is formed with a protrusion 122a to reduce the contact area when the plate member 124 is coupled to the plate 122. Therefore, the amount of adhesive may be reduced when the thin plate member 124 is adhered to the plate 122. In addition, by forming one end of the protruding portion 122a on the rotating shaft 123 side, the edge portion of the thin plate member 124 adjacent to the rotating shaft 123 is spaced apart from the side surface of the plate 122 by a predetermined distance. It is spaced apart and has a certain elasticity. Of course, the edge portions of the thin plate member 124 protruding from the end of the plate 122 also have a certain elasticity.

Meanwhile, in order to prevent air leakage between the thin plate member 124 and the rotating shaft 123, it is also possible to combine one end of the thin plate member 124 with the rotating shaft 123. That is, as shown in FIG. 8, one end of the thin plate member 124 is adhered to the rotary shaft 123, or a groove (not shown) is formed in the rotary shaft 123 and the thin plate member 124 is formed in the groove. You can also join one end.

In addition, when the flow path is closed by the rotation of the door 121, only the edge portion of the thin plate member 124 is in close contact with the air conditioning case 110 side to close the flow path, wherein the plate 122 is the A stopper 122b protrudes from an end portion of the plate 122 so as not to be caught over by the air conditioning case 110.

In addition, as shown in FIG. 9, both sides of the plate 122 may be tapered to be inclined at a predetermined angle. In this case, the thin plate member coupled to the both sides of the plate 122 by the hook 125 or by adhesion. 124 is also inclined at a predetermined angle, respectively, so that one end is in contact with each other.

When one end of the pair of thin plate members 124 coupled to both side surfaces of the plate 122 is in contact with each other, it is possible to prevent noise from occurring while the wind enters between the pair of thin plate members 124. .

On the other hand, as described above, both sides of the plate 122 may be formed to be inclined at a predetermined angle, but if necessary, at least one side of the plate 122 may be formed to be inclined at a predetermined angle.

11 is a perspective view showing a door according to another embodiment of the present invention. In the above, the flat plate-like thin plate members 124 are coupled to both side surfaces of the plate 122, but the thin plate member 124 is shown in FIG. ) Is bent into a "U" shape and both ends thereof are respectively coupled to both sides of the plate 122.

At this time, the combining method is the same as described above.

In addition, the portion bent in the "U" shape of the thin plate member 124 also protrudes outward from the end of the plate 122.

In addition, when the flow path in the air conditioning case 110 is closed by the door 121, the portion bent in the “U” shape is sealed while elastically contacting the air conditioning case 110.

Hereinafter, the operation of the door for a vehicle air conditioner according to the present invention will be described.

First, the air blown by the blower not shown is changed to cold while passing through the evaporator 101.

Or it is changed to warmth while passing through the heater core 102 through the hot air passage (P2).

Subsequently, the cold air or the warm air that has selectively passed through the cold air flow passage P1 and the hot air flow passage P2 is driven through the vents 112 to 115 whose opening degree is adjusted by the mode door 120b according to the air conditioning mode. It is supplied to the room to cool or heat the inside of the car.

When the temperature control door 120a closes the cold air flow passage P1 or the hot air flow passage P2, or when the mode door 120b closes the flow path toward each of the vents 112 to 115, the plate is closed. An edge portion of the thin plate member 124 protruding from the end of the 122 is elastically in contact with the inner wall surface side of the air conditioning case 110.

As such, when the door 121 installed in the air conditioning case 110 closes the flow path toward the cold air flow passage P1, the hot air flow passage P2, or the vents 112 to 115 in the air conditioning case 110, The edge portion of the thin plate member 124 protruding from the end of the plate 122 is in contact with the circumferential air conditioning case 110 side of the flow path to be sealed.

As described above, the door 121 for the vehicle air conditioner according to the present invention is not only a type in which the plate 122 is formed on only one side of the rotation shaft 123, but each plate on both sides of the rotation shaft 123. The same applies to the center pivot door type in which 122 is formed.

In addition, the vehicle air conditioner door 121 may be applied to all kinds of doors including the temperature control door 120a, the mode door 120b, or the internal and external air conversion doors.
