The air outlet 112 includes a defrost vent 113 for discharging air toward the windshield of the vehicle, a face vent 114 for discharging air toward the face of the occupant, And a floor vent 115. Accordingly, the openings of the vents 113, 114, and 115 are opened and closed by the mode doors 113a, 114a, and 115a, and various ventilation modes (vent mode, floor mode, Level mode, and a mix mode).

An evaporator 101 and a heater core 102 are sequentially installed in the air conditioning case 110 at predetermined intervals and the evaporator 101 is interposed between the evaporator 101 and the heater core 102, A temperature control door 120 for controlling the mixing amount of warm air passing through the heater core 102 and the cool air is provided.

A blower 103 is installed on the side of the air inlet 111 of the air conditioner case 110 so as to blow the inside air or the outside air into the air conditioner case 110.

A portion of the air in the mixing region MC where the air passing through the evaporator 101 and the air passing through the heater core 102 are mixed is drawn out to the outlet side of the air conditioning case 110, The seat vent 150 is formed so as to be able to supply the sheet vent 150.

The seat vent 150 is formed on the side of the floor vent 115. That is, the seat vent 150 is divided into left and right portions of the floor vent 115 to be partitioned therebetween.

The inlet of the seat vent 150 is formed in the downstream of the mixing region MC adjacent to the mixing region MC where the coolant passing through the evaporator 101 and the warmer passing through the heater core 102 are mixed.

In this way, air is drawn out from the mixing region MC where air passing through the evaporator 101 and air passing through the heater core 102 are mixed through the sheet vent 150 and supplied to the seat 10 side A separate temperature control door for controlling the temperature of the air supplied to the seat 10 is not required and a certain amount of conditioned air can be supplied to the seat 10 regardless of the air conditioning mode.

A seat side heat exchanger (153) is installed in the seat vent (150) so that air passing through the seat vent (150) is heat - exchanged to cool and warm the vehicle seat (10).

The seat side heat exchanger 153 may be provided with a PTC heater (not shown) or a thermoelectric module (not shown) as the seat side heat exchanger 153. The seat side heat exchanger 153 may be a heat exchanger having at least one function of cooling or heating. Is preferably used.

Therefore, the temperature of the supply air on the seat 10 side is primarily adjusted only by the temperature control door 120 provided in the air conditioning case 110, and the insufficient cooling / heating load is further reduced by using the seat side heat exchanger 153 It will be supplemented.

The evaporator 101 and the heater core 102 as well as the seat side heat exchanger 153 are all installed in the air conditioning case 110 so that the module can be modularized and the productivity can be improved.

In the case where the PTC heater is installed as the seat side heat exchanger 153, if the rapid heating is difficult at a low temperature as in winter, power is supplied to the PTC heater to rapidly supply warm air to the seat 10, Respectively.

Also, when cooling is required in the summer, the seat 10 can be cooled using cold air passing through the evaporator 101 of the air conditioner 100.

At this time, when the passenger desires only the air blown from the air conditioning apparatus 100, air is supplied to the seat 10 in the cooling / heating mixing area MC of the air conditioning case 110, If the air is too cold and needs to be heated, the PTC heater can be activated to control the temperature.

Further, a thermoelectric module capable of performing both the cooling and heating functions can be used as the sheet side heat exchanger 153. In the thermoelectric module, one end performs an endothermic action in accordance with the current flow direction, (Not shown) acting on the thermoelectric element and heat exchange pins (not shown) provided on both sides of the thermoelectric element.

Since the thermoelectric module can heat and heat simultaneously by switching the polarities of current (+, -), the air passing through the seat vent 150 is heated or cooled and supplied to the seat 10 side, (10) can be cooled and / or warmed. That is, if the polarity of the current applied to the thermoelectric element is changed, the heat exchange pin located on the passage of the seat vent 150 can be made cold or hot, so that cooling / heating can be switched. Therefore, the occupant can select the cooling and heating by the air conditioner control switch (not shown).

When air is drawn out from the mixing region MC of the air conditioning apparatus 100 and supplied to the seat 10 side because the cooling and heating performance of the air conditioning apparatus 100 is insufficient at the initial stage of starting the vehicle, The heating and cooling performance is also insufficient. When the cooling and heating performance of the air conditioner 100 is insufficient at the initial stage of the start of the vehicle, the thermoelectric module or the PTC heater is actuated to quickly cool or warm the air to the seat 10, Can be improved.

In addition, after the cooling / heating performance of the air conditioner 100 is sufficiently secured, the operation of the seat side heat exchanger 153 may be stopped.

A seat duct 105 is installed at an outlet of the seat vent 150 to supply air passing through the seat vent 150 to the seat 10 of the vehicle.

The seat duct 105 connects the outlet of the seat vent 150 to the seat 10 of the vehicle and the inlet of the seat duct 105 is connected to the outlet of the seat vent 150 However, the outlet of the seat duct 105 may be branched into a plurality of portions to be connected to the front seat left and right seat 10 of the vehicle, or to all the front seat / rear seat of the vehicle.

Meanwhile, it is preferable that the seat duct 105 is formed of a flexible variable duct so that smooth air supply is possible even when the vehicle seat 10 is moved.

In addition, a sheet-side air blower 152 is installed inside the seat vent 150. The sheet-side air blower 152 is installed on the inlet side of the seat vent 150 to forcibly suck air in the mixing region MC of the air-conditioning case 110 and blow it toward the seat 10 side.

A door 151 is provided at the entrance of the seat vent 150 to open and close the entrance of the seat vent 150. The door 151 is preferably disposed upstream of the seat-side air blower 152.

In addition, since the door 151 is opened only when the seat 10 is cooled and / or warmed, loss of airflow during air conditioning of the front seat of the vehicle is minimized.

On the other hand, when there are a plurality of sheets 10 to be cooled and / or heated in the vehicle, as described above, the sheet ducts 105 may be divided into a plurality of sheets to heat and heat the plurality of sheets 10 at the same time, A plurality of the seat side heat exchangers 153 and the blowers 152 may be provided in the inside of the seat 150 and a plurality of the seat ducts 105 may be provided corresponding thereto to cool and heat the plurality of seats 10 simultaneously.

5 is a view showing a case where a seat side air blower is installed in a seat duct in a vehicle air conditioner according to the present invention. In the above description, the seat side air blower 152 is disposed inside the seat vent 150 5, a sheet-side air blower 152a may be provided on the upstream side of the seat duct 105 provided outside the air conditioner 100. [

That is, only the seat side heat exchanger 153 is installed in the seat vent 150 of the air conditioning case 110, and the seat side air blower 152a is installed in the seat duct 105.

In order to supply air to the plurality of sheets 10 using the one sheet-side blower 152a when the outlet of the sheet duct 105 is branched into a plurality of sheets and connected to the plurality of sheets 10, It is preferable that the sheet-side blower 152a is provided on the upstream side of the branching portion of the seat duct 105. [

Hereinafter, the operation of the air conditioner for a vehicle according to the present invention will be described. Only the case where the seat side heat exchanger 153 is composed of a PTC heater will be described for convenience.

First, the inside / outside air selectively introduced by the blower 103 installed at the inlet side of the air conditioner case 110 is cooled while passing through the evaporator 101, and the cooled air is heated by the temperature control door 120 And selectively passes through the heater core 102,

At this time, air (warm air) passing through the heater core 102 or air (cool air) bypassing the heater core 102 is mixed in the mixing region MC, and this air is supplied to each mode door 113a according to various air conditioning modes, 114a, 115a to flow toward each of the vents 113, 114, 115, and then discharged to the inside of the car to cool and heat the inside of the car.

On the other hand, when the passenger operates the seat heating / cooling mode for cooling / heating the seat 10, the door 151 installed at the entrance of the seat vent 150 is opened and the seat side air blowers 152 and 152a also operate A part of the air in the mixing area MC in the air conditioning case 110 is supplied to the seat 10 through the seat vent 150 and the seat duct 105 to cool and heat the seat 10.

That is, as described above, when rapid heating of the seat 10 is difficult at a low temperature as in the winter, power is supplied to the PTC heater, which is the seat side heat exchanger 153, so that warm air is rapidly supplied to the seat 10 . Also, when cooling is required in the summer, the seat 10 can be cooled using cold air passing through the evaporator 101 of the air conditioner 100.

When the passenger desires only the air blown from the air conditioning apparatus 100, the air in the cooling / heating mixing region MC of the air conditioning case 110 is taken out and supplied to the seat 10, If the air is too cold, when the heating is needed, the PTC heater is activated and the temperature can be adjusted.

In this way, by integrating the seat side heat exchanger 153 and the seat side air blower 152 in the vehicle air conditioner 100, the space on the side of the seat 10 can be ensured and the passenger can be heat- Since the air in the cooling and heating mixing area MC of the air conditioning case 110 can be utilized, the efficiency can be increased, the consumption of energy can be reduced, the cooling and heating performance of the seat 10 can be improved, The assemblability can be improved.

According to the present invention, since the seat vent is formed in the air conditioning case, and the seat side heat exchanger and the seat side air blower are integrally formed, space for installing the convenience device in the seat can be ensured, In addition to utilizing the air in the warm mixing area and insufficient cooling / heating load, the efficiency is increased because it is supplemented by using the seat side heat exchanger, thereby reducing energy consumption and improving the cooling and heating performance of the seat.

In addition, since the single seat side heat exchanger and the blower can cope with the cooling and heating of a plurality of sheets, and the existing automotive air conditioner is used, the number of parts is reduced and the assembling property is improved.

Further, since a part of the air in the mixing region of the air conditioning case is supplied to the seat side, a separate temperature control door for adjusting the temperature of the air supplied to the seat side is not required.

In addition, since the evaporator and the heater core as well as the seat side heat exchanger are all installed in the air conditioner, modularization is possible and productivity is improved.

Then, air is drawn out from the mixing area in the air conditioning case and supplied to the seat side, so that a certain amount of air conditioning air can be supplied to the seat side regardless of the air conditioning mode.
