The present invention relates to a seat air conditioner for a vehicle, and more particularly, by diverting some of the air supplied to the rear seat through the console duct to the seat side and installing a thermoelectric module at the branch point to perform seat air conditioning. By using the console duct, the space required for cooling and heating the sheet can be minimized and the number of parts can be reduced. The overall structure is also simple, which reduces the manufacturing cost. It is possible to secure the installation space of the various convenient devices in the interior and to further improve the seat air-conditioning performance by using the performance of the front air conditioning device relates to a vehicle seat air conditioning device.

In general, the vehicle air conditioner is a vehicle interior that is installed for the purpose of securing the driver's front and rear view by removing the frost that is caught in the windshield during the rainy season or the winter, or by cooling or heating the interior of the car during the summer or winter season. These air conditioners are usually equipped with a heating device and a cooling device at the same time, and by selectively introducing the inside or outside air through a blower unit, the air is heated or cooled and blown into the interior of the vehicle to cool, heat or ventilate the interior of the car. Done.

According to the independent structure of the blower unit, the evaporator unit and the heater core unit, the air conditioner has a three-piece type in which the three units are independently provided, the evaporator unit and the heater core unit are built in the air conditioning case, and the blower unit is Semi-center type is provided as a separate unit, and all three units can be divided into a center mounting type that is built in the air conditioning case.

In addition, the two-layer air conditioner has been developed to maintain a high heating performance while ensuring a defogging performance during heating. In other words, low temperature cold air is effective when removing the frost on the window during winter heating run, the general automotive air conditioning system is configured to remove the frost by introducing a low temperature cold air, because of this, the room temperature is low Loss results. In the above case, the two-layer air conditioner realizes two-layer air flow between the upper part of the vehicle and the lower part of the outside air by circulating the inner part. It effectively removes air while providing fresh outside air to the occupants and provides a warm bet under to maintain high heating performance.

The air conditioners described above are usually the front air conditioners for the front seats, and there is a rear air conditioner for the rear seats. On the other hand, a separate rear air conditioner may be installed for air conditioning of the rear seat, but the rear air conditioning may be performed by directly supplying heat exchanged air from the front air conditioner to the rear seat by installing a console duct on the outlet side of the front air conditioner. do.

In the air conditioner, the vehicle seat which cools and heats the seat of the vehicle by bypassing the heat exchanged heat from the front air conditioner to the front seat of the vehicle in association with the front air conditioner, thereby comforting the occupant's back and hips. Various air conditioners have also been proposed, and FIG. 1 shows an example of such a vehicle seat air conditioner (Japanese Patent Laid-Open No. 1999-263116 (1999.09.28)).

The vehicle seat air conditioner as shown in FIG. 1 includes a connection duct 30 connected to the vehicle seat 10 from the air conditioning case 21 constituting the front air conditioner 20, and the connection duct 30.

That is, the ventilation seat 12 is formed in the vehicle seat 30 so as to discharge the air toward the passengers, and the connection duct 30 is connected to the ventilation path 12, so that the air conditioner is driven by driving the blower 40. Air can be efficiently blown from the discharge port of the case 21 toward the ventilation path 12 through the connection duct 30. In this process, the air blown through the blower 40 toward the ventilation path 12 is heat-exchanged while passing through the heat exchanger 50 to cool and heat the sheet.

However, in the conventional vehicle seat air conditioner, as the seat air conditioner including the heat exchanger 50 and the blower 40 is mounted on the seat 10 side, the space inside the seat 10 becomes insufficient. For this reason, since a small heat exchanger 50 must be used, there is a problem that sheet cooling and heating performance is deteriorated.

In addition, since each heat exchanger 50 and a blower 40 are required for each seat (driver's seat, passenger seat, etc.), several seat air conditioners are required for a single vehicle, which not only complicates the overall structure but also makes each seat 10 a. As the same parts are mounted, the number of parts also increases, leading to increased manufacturing costs.

In addition, since a large part of the space inside the seat 10 should be devoted to the seat air conditioner, there is a problem that the assembly work is difficult due to the space constraints when installing various other devices.

An object of the present invention for solving the above-mentioned problems is to provide a sheet air by branching some of the air supplied to the rear seat through the console duct to the seat side, and to install the thermoelectric module at the branch point to perform the sheet air conditioning, The use of ducts minimizes the space required for seat cooling and heating, reduces the number of parts, and reduces the manufacturing cost by simplifying the overall structure. In addition, it enables independent cooling and heating of the seat, while securing space inside the seat. It is possible to secure an installation space of a convenient device and to provide a vehicle seat air conditioner by improving the seat cooling and heating performance by further using the performance of the front air conditioner.

In order to achieve the above object, the present invention extends from the console vent of the front air conditioner to the rear side of the console box so as to directly supply some of the air discharged from the front air conditioner to the rear seat, and separate air passages for the left and right sides. In the vehicle air conditioner comprising a console duct, the console duct is divided into a front duct and a rear duct is connected / coupled between the divided front and rear ducts and the front, rear, the front, A connecting passage for communicating the air passage of the rear duct and a seat passage in a lower direction, and a seat duct for connecting the seat passage of the left and right connecting ducts and the seat side of the vehicle to communicate with each other; And installed in the left and right connection ducts, and branching some of the air blown into the rear seats through the console ducts. And opening and closing means for adjusting the opening and closing amounts of the connection passage and the sheet passage so as to selectively supply the sheet side, and heat exchange means installed at a downstream side of the sheet passage to heat-exchange the air passing through the sheet passage. It is characterized by.

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

That is, the console duct 25d extends from the air conditioning case 21 to the rear side of the console box (not shown) of the vehicle, thereby discharging air toward the face of the rear occupant.

On the other hand, the vents 25a, 25b, 25c for discharging air to the front seat and the vents 25d and 25e for discharging air to the rear seat are both a plurality of doors 24 installed in the air conditioning case 21. The amount of opening and closing is adjusted by).

Since the front air conditioner 20 is well known, a detailed description thereof will be omitted.

The vehicle seat air conditioner 100 of the present invention comprises a left and right connection duct 110, seat duct 120, opening and closing means 113, heat exchange means 130, the console duct 101 The left and right connection ducts 110 are installed at approximately mid-points of the air, and part of the air discharged from the air conditioning case 21 to the console duct 101 is supplied to the seat 10 of the vehicle. Of course, the installation position of the left and right connection duct 110 is installed in the console duct 101 according to the type and structure of the vehicle can be variously changed.

The console duct 101 extends from the console vent 25d, which is the outlet of the air conditioning case 21, to the rear side of the console box, and is divided into both left and right sides from the inlet to the outlet. Have a furnace. Therefore, it is possible to discharge the air to all the occupants in the left and right of the rear seat. If the front air conditioner 20 is a left and right independent control method, it is possible to discharge the air of different temperatures to the occupants on the left and right of the rear seat.

The left and right connection ducts 110 divide the console duct 101 into a front duct 102 and a rear duct 103 to be connected between the divided front and rear ducts 102 and 103. In addition, the left and right connecting passages 111 for communicating the respective left and right air passages 102a and 103a of the front and rear ducts 102 and 103 are formed in the front and rear directions. In the lower direction, a seat passage 112 is formed to supply air to the seat side 10 (driver's seat and passenger seat) of the vehicle.

That is, the console duct 101 is divided into the front duct 102 and the rear duct 103 in the front and rear directions, and each end of the divided front and rear ducts 102 and 103 is the left side. , Connected to the front and rear ends of the right connection duct 110, respectively.

In this case, the independent left and right air passages 102a and 103a of the front and rear ducts 102 and 103 may be independently of the left and right connection passages 111 of the left and right connection ducts 110, respectively. Communicate.

In addition, the seat duct 120 is connected to the seat passage 112 and the seat 10 side formed in the lower direction of the left, right connection duct 110 in communication. At this time, since the seat 10 of the vehicle moves in the forward and backward directions, the seat duct 120 may also be configured in a flexible structure (variable duct) that can flow in response to the movement of the seat 10. It is desirable to ensure that the air can be supplied smoothly even if the movement.

On the other hand, it is preferable that the ventilation path 12 is formed inside the seat 10 to which the outlet side of the seat duct 120 is connected so that air supplied through the seat duct 120 can be discharged toward the occupant. .

In addition, the opening and closing means 113 is installed in the left and right connection duct 110 and branched part of the air blown to the rear seat through the console duct 101 to selectively supply to the seat 10 side. The opening and closing amounts of the connection passage 111 and the seat passage 112 are adjusted to be possible.

The opening and closing means 113 is rotatably installed in each connection passage 111 of the left and right connection duct 110 to control the opening and closing amount of the connection passage 111 and the seat passage 112 ( 114 and a driving means 115 installed in at least one of the left and right connection ducts 110 to rotate the door 114.

The door 114 is composed of a rotating shaft 114b rotatably coupled to the inner walls of the left and right connection duct 110, and a flat plate 114a formed on one side of the rotating shaft 114b. The plate 114a is installed to face the direction opposite to the direction of the wind flowing in the connection passage 111.

In addition, between the left and right connection duct 110, a connection member 118 for connecting the rotary shaft 114b of each door 114 installed in each connection passage 111 is further installed, one driving means 115 allows the doors 114 to operate simultaneously.

Here, the coupling of the connection member 118 and the rotary shaft 114b, as shown in Figure 4, extending one end of the rotary shaft 114b provided in each connection passage 111 toward the connection member 118, the connection member Insert / engage at both ends of (118). At this time, a plurality of protrusions (not shown) are formed on the outer circumferential surface of the rotating shaft 114b, and a plurality of grooves (not shown) are fitted on the inner circumferential surfaces of both ends of the connecting member 118 into which the end of the rotating shaft 114b is inserted. Is formed.

Therefore, the door 114 installed in each connection passage 111 of the left and right connection duct 110 can be operated at the same time by one driving means 115.

On the other hand, although not shown in the drawing, the connection member 118 is omitted, and the drive means 115 are installed on both sides of the left and right connection duct 110, respectively, the doors installed in the respective connection passages 111 ( 114 can also be operated independently. That is, by independently controlling each door 114 installed in the left and right connection passages 111 by the two driving means 115, it is supplied to the rear seat through the console duct 101 or the seat duct 120 Through the seat side 10, the driver's seat and the passenger seat is to be able to individually control the amount of air left and right.

And, the driving means 115 for operating the door 114, the cam 116 is installed to rotate by the drive of the motor 116b on one side of any one of the left, right connection duct 110, A guide 117a coupled to an end of the rotation shaft 114b drawn out to the outside of the left and right connection duct 110 and slidably coupled to the sliding groove 116a of the cam 116 protrudes from the end side. The lever 117 is formed.

Therefore, when the cam 116 is rotated by the driving of the motor 116b, the lever 117 coupled to the sliding groove 116a of the cam 116 as the guide 117a rotates while the rotation shaft ( The door 114 is operated by rotating 114b).

In addition, a reinforcing member 119 having a predetermined length is formed between the left and right connection ducts 110 to support the left and right connection ducts 110 and to maintain a predetermined distance from each other.

In addition, a heat exchange means 130 is installed on the downstream side of the seat passage 112 to heat-exchange the air passing through the seat passage 112. The heat exchange means 130 is a thermoelectric module in the seat duct 120. This is achieved by installing 131.

Here, the thermoelectric module 131 is installed on both sides of the thermoelectric element 132 and the thermoelectric element 132 on one side of the endothermic action and the other side of the thermoelectric element 132 according to the flow direction of the current Consisting of heat exchange fins 133.

Since the thermoelectric module 131 is capable of absorbing and generating heat at the same time through the pole (+,-) switching of current, the sheet 10 may be heated or cooled through the sheet duct 120. ) Can be heated and heated. That is, when the polarity of the current applied to the thermoelectric element 132 is changed, the heat exchange fin 133 located at the side through which the air supplied to the sheet 10 passes may be cold or hot, and thus the heating and cooling may be switched. Therefore, the occupant can select the heating and cooling by the air conditioning control switch (not shown).

On the other hand, as the heat exchange means 130, not only the thermoelectric module 131 but also a PTC auxiliary heater (not shown) may be installed. That is, when rapid heating is difficult at a low temperature such as in winter, power is supplied to the PTC auxiliary heater. It can be supplied to quickly supply warm air to the sheet (10). In addition, when cooling is required in the seat 10 side in the summer, at the initial start of the vehicle, the cooling function using the thermoelectric module 131 is operated to supply cool air to the seat 10 side, and after a time, the front air conditioning apparatus When the cooling performance of the 20 is secured, the sheet 10 may be cooled by using cold air discharged from the front air conditioner 20. At this time, when the cooling performance of the front air conditioner 20 is secured, the operation of the thermoelectric module 131 may be stopped, and when the air discharged from the front air conditioner 20 is too cold, the PTC auxiliary heater may be removed. Temperature control is possible by operating or heating the thermoelectric module 131.

That is, since the air conditioning performance of the front air conditioner 20 is insufficient at the initial start of the vehicle, if the air discharged from the front air conditioner 20 is supplied to the seat 10 side, the air conditioning performance of the seat 10 is also insufficient. Done. As described above, when the cooling and heating performance of the front air conditioner 20 is insufficient at the initial start of the vehicle, as described above, the thermoelectric module 131 or the PTC auxiliary heater is operated to quickly cool or warm the air to the seat 10 side. By supplying, sheet cooling and heating performance can be improved.

In addition, downstream of the thermoelectric module 131, air required for air conditioning of the sheet 10 among the air heat exchanged through the thermoelectric module 131 is sent to the seat duct 120 and unnecessary air is required for air conditioning of the sheet 10. The switching door 140 is installed to control the air flow to be sent to the vehicle cabin.

The switch door 140 is rotatably installed on one side wall of the seat duct 120, and is opened and closed by the switch door 140 on one side wall of the seat duct 120 in which the switch door 140 is installed. In addition, the discharge hole 121 is formed to discharge the air unnecessary for air conditioning the seat 10 into the vehicle cabin.

The switching door 140 closes the discharge hole 121 or rotates to the intermediate point of the thermoelectric module 131 according to whether the thermoelectric module 131 is operated to open the discharge hole 121. Open.

That is, when the cooling and heating performance of the front air conditioner 20 is secured, the operation of the thermoelectric module 131 is stopped to use only the air discharged from the front air conditioner 20, in which case the front air conditioner Some of the air discharged from the console vent (25d) of (20) is branched by the door 114 of the left and right connection duct 110 to flow to the seat duct 120, the door 114 By closing the discharge hole 121 so that the air branched toward the seat duct 120 flows along the seat duct 120 so as not to leak into the discharge hole 121.

On the contrary, when the cooling and heating performance of the front air conditioner 20 is not secured, the thermoelectric module 131 is cooled and heated to heat exchange the air discharged from the front air conditioner 20 again. Due to the characteristics of 131, one side of the air heat exchanged while passing through the thermoelectric module 131, based on the thermoelectric element 132, is heat-exchanged with air required for air conditioning of the sheet 10, while the other side is unnecessary air for air-conditioning the sheet 10. Heat exchanger. Therefore, when the thermoelectric module 131 is operated, the switching door 140 rotates to an intermediate point of the thermoelectric module 131 to move the downstream side of the thermoelectric module 131 to the seat duct 120. By dividing the passage toward the interior and the passage toward the vehicle cabin air required for air conditioning the seat 10 to the seat duct 120 and the air unnecessary for air conditioning the seat 10 is sent to the vehicle interior.

In this way, since the cooling and heating performance of the front air conditioning apparatus 20 can be additionally used in the cooling and heating performance of the thermoelectric element module 131 of the seat air conditioning apparatus 100, the seat can be quickly cooled and heated at the beginning of the vehicle. (10) It can improve air-conditioning performance.

In addition, a blower fan 150 may be further installed at a downstream side of the thermoelectric module 131, which is the heat exchange unit 130. In the drawing, the blowing fan 150 is installed downstream from the conversion door 140. Therefore, independent cooling and heating of the seat 10 is possible regardless of whether the front air conditioner 20 is movable. That is, even when the engine of the vehicle is stopped and the front air conditioner 20 does not operate, when the thermoelectric module 131 and the blower fan 150 of the seat air conditioner 100 are operated, the seat 10 is operated. It can be heated independently.

As such, since the independent cooling and heating of the seat 10 is possible, the heating and cooling performance may be exhibited if proper power can be supplied even when the vehicle is parked. In addition, by using the console duct 101 to achieve the heating and cooling of the seat 10 to minimize the space occupied by the seat air conditioner 100 in the vehicle, and also to efficiently the air of the front air conditioner (20) to the seat 10 Since the dispensing is possible, the heating and cooling performance of the front air conditioning apparatus 20 may be additionally used in the seat air conditioning apparatus 100, thereby maximizing the heating and cooling performance of the sheet 10. That is, when the front air conditioner 20 is in operation, the seat 10 cooling and heating performance can be further improved.

In addition, since the seat air conditioner 100 may be independently operated, ventilation and a ventilation sheet may be configured by using power generated from a solar cell or power of a vehicle battery when the vehicle is parked. That is, the surface temperature of the sheet 10 may be lowered by introducing external air through the operation of the blower fan 150 and supplying the sheet 10 to the seat 10 during parking. In addition, the indoor air of high temperature escapes to the outside of the vehicle to introduce the outside air, thereby lowering the average indoor temperature. Therefore, when the passenger enters the room, the comfort can be improved and the air conditioner can be quickly lowered to the desired temperature, thereby reducing energy consumption.

On the other hand, the above has been described only for supplying the heating and cooling air to the seat 10 side, that is, the driver's seat side and the passenger seat side seat 10, but the seat 10 to be cooled and heated in the vehicle including the rear seat seat a number of days In this case, the left and right connection ducts 110, the door 114, and the seat duct 120 may be added to the console duct 101 to supply cooling and heating air.

Hereinafter, the operation of the vehicle seat air conditioner 100 according to the present invention will be described.

First, in the cooling or heating operation of the front air conditioning apparatus 20, the cold air or warm air discharged from the defrost vent 25a, the face vent 25b and the floor vent 25c of the air conditioning case 21 moves to the front seat. The cold air or warm air supplied from the console vent 25d of the air conditioning case 21 is supplied to the rear seat through the console duct 101.

That is, when the vehicle air conditioner does not operate the seat air conditioning, as shown in Figure 5, the door 114 installed in the left and right connection duct 110, the connection passage 111 is completely opened and the seat passage 112 ) By completely closing, the air discharged from the console vent (25d) of the air conditioning case 21 is connected to the front passage duct 102 of the console duct 101 and the connecting passage 111 of the left and right connection duct 110 and It is only supplied to the rear seat through the rear duct 103 of the console duct 101. At this time, the thermoelectric module 131 is in a stopped state.

When the air conditioning the seat 10 is operated, as shown in FIGS. 6 and 7, the door 114 installed in the left and right connection ducts 110 is controlled by the driving means 115. The opening 112 is opened, and the air volume supplied to the rear seat and the air volume supplied to the seat 10 are adjusted according to the position of the door 114.

6, the case in which the door 114 opens both the connection passage 111 and the seat passage 112 is discharged from the console vent 25d of the air conditioning case 21. Cold air or warm air enters the connection passage 111 of the left and right connection duct 110 through the front duct 102 of the console duct 101, and the air entering the connection passage 111 is Branched by the door 114, a part is supplied to the rear seat through the rear duct 103 of the console duct 101, the rest to the seat 10 through the seat passage 112 and the seat duct 120 Supplied.

Thereafter, the air supplied to the seat 10 is discharged toward the occupant through the ventilation path 12 in the seat 10 to cool and heat the seat 10.

Subsequently, as shown in FIG. 7, when the door 114 completely closes the connection passage 111 of the left and right connection ducts 110 and completely opens the seat passage 112, the air conditioning case 21 may be used. The air discharged from the console vent (25d) of the) is the seat 10 through the front duct 102 of the console duct 101 and the seat passage 112 and the seat duct 120 of the left and right connection duct 110 It is supplied only to the side.

In addition, the thermoelectric module 131 is selectively operated in FIGS. 6 and 7, in which the air conditioner 10 operates as described above. That is, when the cooling and heating performance of the front air conditioning apparatus 20 is secured, the cold air or warm air discharged from the console vent 25d of the front air conditioning apparatus 20 to flow the console duct 101 is used for the air conditioning of the seat 10. Since the thermoelectric module 131 stops operating, on the contrary, when the cooling and heating performance of the front air conditioner 20 is not secured, such as at the beginning of the vehicle, the thermoelectric module 131 is preferably operated. Do. Of course, when the rapid cooling and cooling of the seat 10 is required, the thermoelectric module 131 may be operated even when the cooling and heating performance of the front air conditioner 20 is secured.

In addition, when the heating and cooling performance of the front air conditioner 20 is secured and the operation of the thermoelectric element module 131 is stopped, the conversion door 140 installed downstream of the thermoelectric element module 131 may discharge the discharge hole ( 121 is closed to prevent leakage of the cold or warm air discharged from the front air conditioner 20 into the discharge hole 121 when the cold air or warm air flows into the sheet duct 120.

In addition, when the thermoelectric module 131 operates, the switching door 140 rotates to an intermediate point of the thermoelectric module 131 to open the discharge hole 121 to open the thermoelectric module ( The air required for the air conditioning of the sheet 10 in the heat exchanged air is divided into two parts: a downstream side of the 131 into a passage facing the seat duct 120 and a passage facing the vehicle interior, and passes through the thermoelectric module 131. 120, the air unnecessary for air conditioning of the seat 10 is sent to the vehicle compartment.

On the other hand, the air supplied to the seat 10 side through the seat air conditioner 100 according to the present invention is air that is heat-exchanged with cold air or warmth to meet the cooling and heating requirements of the occupant in the front air conditioner 20, and thus the air conditioning of the occupant Sheet air conditioning can be performed according to the needs.
