1 to 11, a temperature control apparatus for a vehicle seat according to a preferred embodiment of the present invention is provided with a housing 4 having a suction port formed on one side of a seat bottom of a vehicle, A heat exchanging module (1) is provided in an intermediate portion of an internal flow path in which air forcedly blown by the blowing fan (2) is moved, and an internal flow path before passing through the heat exchanging module (1) And a bimetal 5 is mounted on the heat exchange module 1. [ The heat exchanged air passing through the heat exchange module 1 is guided to the inside of the backrest or the cushion through the connection duct through the discharge port formed on the other side of the housing 4.

The air supplied by the cushion is guided through an air passage formed inside the cushion, and is discharged through the surface of the cushion to be delivered to a person sitting on the cushion.

The heat exchange module 1 may be a PTC (PTC) or a thermoelectric element (TED) may be used. In the case where the heat exchange module 1 is used as a heat exchanger, it is possible to perform cooling through heating for supplying heated air and ventilation for blowing air only. When the thermoelectric element (TED) is used as the heat exchange module (1), it is possible to perform heating for supplying heated air and cooling for blowing cooled air. There are some differences in the cooling control method and the heating control method of the vehicle seat depending on the case where the heat exchange module 1 is used and the case where the thermoelectric element is used.

Further, a bimetal is installed in the heat exchange module (1). The bimetal operates normally when the applied current is less than or equal to the allowable current, and prevents the overheat by blocking the flow of current when it is large.

Also, the meaning of the step number control described below means that the duty value applied to the thermoelectric element (TED) is fixed for each step during cooling, and the set temperature for heating. That is, at the time of heating, the duty value is determined based on the suction temperature and the set temperature. Here, the duty value refers to the relationship between the voltage and the supplied time. For example, when the duty value is 50%, the voltage V is adjusted so that the time during which the voltage is applied in a fixed state is reduced to 1/2. The difference between the case where the duty value is 100% and the case where the duty value is 50% is that the applied power amount is different because the applied time is reduced to 1/2.

1 to 3, a temperature control apparatus for a vehicle seat according to a first preferred embodiment of the present invention includes a thermoelectric element TED (thermoelectric element) for supplying temperature-controlled air to a seat made of a cushion C and a backrest B, And a heat exchanging module (not shown). Two heat exchange modules 1 mounted on the inside of the housing 4 are mounted on both sides with respect to the blowing fan 2 and a discharge port formed on one side of the housing 4 is connected to the connecting duct 11, And conveys the blown air into the inside of the backrest (B). The discharge port formed on the other side of the housing 4 is connected to the connecting duct 12 to transmit forced air into the interior of the cushion C. [

The process of cooling the temperature controller of the seat configured as described above is as follows.

When the cooling selection step (T1) for selecting cooling is selected in a state where the power supply step for supplying power to the cooling / heating apparatus of the vehicle seat is performed, the rotational speed of the blowing fan (1) and the set value of the heat exchange module And a cooling level selection step (T2) for selecting the cooling level.

The cooling level selection (T2) refers to setting the predetermined value in one stage, two stages, three stages, and N stages. In the present invention, the setting of the first stage, the second stage and the third stage Let us explain it as an example. Each stage refers to the duty value described above, and adjusting the duty value means controlling the time that the voltage is applied under a certain voltage. That is, the rotational speed of the blowing fan 2 increases and the duty value of the heat exchange module 1 increases as it goes from the first stage to the third stage. The fact that the duty value of the heat exchange module 1 is increased means that the cooling performance and the heating performance are improved and the heat exchange ability is improved.

When the cooling level selection is completed, a blowing fan operation step (T3) is performed in which power is supplied to the blowing fan (2) so that external air can be blown toward the heat exchange module (1). At this time, the rotational speed of the blowing fan 2 to be operated is determined according to the number of stages selected in the preceding cooling level selection step T2.

Next, a suction temperature sensing step (T4) for measuring the temperature of the air supplied to the heat exchange module (1) by the temperature sensor (3) is performed. It is most preferable that the temperature sensor 3 is mounted in an internal flow passage through which forced forced air supplied to the heat exchange modules 1 on both sides through the blowing fan 2 passes. At this time, the temperature sensor 3 may be configured to be mounted on the outer circumferential surface of the housing 1 or on the suction port side formed in the housing 1, in addition to the inner flow path. Also, although there may be a difference in measured temperature, a temperature sensor may be installed inside the vehicle, and the temperature of the air inside the vehicle supplied to the heat exchange module 1 may be measured and used.

Next, a judgment step (T5) for judging whether the temperature measured by the temperature sensor (3) is equal to or lower than the stop temperature is performed. At this time, the stop temperature is preferably set to a predetermined temperature to prevent overcooling of the thermoelectric element (TED) which is the heat exchange module (1). The stop temperature can be controlled by the operator depending on the climate characteristics of the area where the vehicle is used and the environment in which it is used.

If the temperature of the intake air measured in the determination step T4 is equal to or less than 10 degrees set as the stop temperature, an operation stopping step T6 for not supplying power to the heat exchange module 1 is performed. At this time, the operation of the air blowing fan 2 is still in a state in which it is still carried out.

After the operation stopping step T6, an end determining step T7 for determining whether there is a user end signal for proceeding to the ending step T8 for shutting off the power supplied to the blowing fan 2 or the heat exchange module 1 ). At this stage, if there is no user's termination signal, the next step proceeds to the suction temperature sensing step (T4). If there is no termination signal as described above, the next step may proceed to the termination of the operation (T6), in addition to the case of proceeding to the suction temperature sensing step (T4).

If the temperature measured in the determination step T4 is not lower than 10 degrees, an operation step T9 for supplying power to the heat exchange module 1 is performed. At this time, the duty value of the thermoelectric element used as the heat exchange module 1 is determined according to the number of stages selected in the step of selecting the number of stages. That is, power is supplied so as to have a duty value of 0% in the case of selecting the first stage, 50% in the case of selecting the second stage, and 100% in the case of selecting the third stage. In the present invention, the number of stages is controlled in three stages from the first stage to the third stage. However, the% value of the supplied power is appropriately adjusted according to the number of steps.

The operation step T9 is followed by an end judgment step of judging whether there is an end signal of the user to proceed to the end step T11 for stopping the operation by shutting off the power supplied to the blowing fan 2 or the heat exchange module 1 (T10). At this stage, if there is no user's termination signal, the next step proceeds to the suction temperature sensing step (T4). If there is no end signal, the next step may proceed to operation step T9, in addition to the case where the operation proceeds to the suction temperature sensing step T4.

When the housing 4 on which the heat exchange module 1 is mounted is provided adjacent to the cushion C, the temperature controlled air is supplied to the connecting duct 11 connected to the inner flow path of the backrest B The backrest feeding step T12 proceeds. The backrest feeding step T12 is performed after the blowing fan operating step T3.

When the housing 4 on which the heat exchange module 1 is mounted is installed adjacent to the backrest B, the cushion C for supplying the temperature-controlled air to the connecting duct 12 connected to the inner flow path of the cushion C, The supply step T13 proceeds. The cushion part feeding step T13 is performed after the blowing fan operating step T3, as in the backrest feeding step T12.

That is, the duty value of the heat exchange module 1 increases as it goes from the first stage to the third stage. The increase in the duty value of the heat exchange module 1 means that the heating is performed at a high temperature.
