It is to be noted that the accompanying drawings are only for the purpose of facilitating understanding of the present invention, and should not be construed as limiting the scope of the present invention with reference to the accompanying drawings.

2 is a block diagram showing a blower ventilation sheet device according to the present invention.

Referring to Fig. 2, the seat ventilating apparatus includes a ventilation switch 50, a temperature measuring section 60, a ventilation section 70, and a control section 80.

The ventilation switch 50 is set so that the occupant can ride on the vehicle and operate the seat ventilator.

The temperature measuring unit 60 includes a first temperature sensor 61 and a second temperature sensor 62. [ The first temperature sensor 61 is installed in the cushion 10 and the second temperature sensor 62 is installed in the bag 20. The first temperature sensor 61 and the second temperature sensor 62 are connected to one The temperature can be measured with the above temperature sensor.

The first temperature sensor 61 and the second temperature sensor 62 can be installed in various shapes or structures in the cushion 10 and the bag 20 in order to effectively measure the temperature. A detailed description thereof will be omitted.

The passage portion 70 includes a first blower 71, a second blower 72 and a duct 73. The first blower 71 and the second blower 72 suck or discharge outside air .

Although the first blower 71 and the second blower 72 are connected to both ends through one duct 73 in the drawing, the first blower 71 and the second blower 72 may be composed of one duct and one blower. In this case, depending on the direction of rotation of the blower, intake can be performed at one end and exhaust can be performed at the other end. At this time, the rotation direction of the blower for determining the intake and exhaust can be determined by the measurement result values of the first temperature sensor 61 and the second temperature sensor 62.

The control unit 80 receives the temperature measurement value from the temperature measurement unit 60 and can control the operation of the bulb 70 based on the received temperature measurement value.

Specifically, the measurement result of the first temperature sensor 61 disposed adjacent to the first blower 71 is higher than the measurement result value of the second temperature sensor 62 disposed adjacent to the second blower 72 The second blower 72 having a relatively low temperature is controlled to be in the intake mode and the first blower 71 having a relatively high temperature can be controlled to the exhaust mode.

The greater the difference between the measured values of the temperature measuring unit 60, the more the degree of operation of the first blower 71 and the second blower 72 can be determined. Specifically, when the difference between the measurement result of the first temperature sensor 61 and the measurement result of the second temperature sensor 62 is equal to or greater than a predetermined temperature difference (for example, 3 degrees), the measurement of the first temperature sensor 61 The difference between the resultant value and the measurement result value of the second temperature sensor 62 is more actively acted than that when the difference is less than the predetermined first temperature difference so that the temperature difference can be canceled out quickly.

If the difference between the measurement result of the first temperature sensor 61 and the measurement result of the second temperature sensor 62 is less than the second temperature difference, a frequent direction change may occur, and thus a hysteresis control method may be used .

In addition to controlling the bulb 70 based on the measurement result of the temperature measuring unit 60, the control unit 70 can also control the bulb 70 based on the operation mode of the ventilation switch.

Specifically, when the air conditioner is operating in the lower mode, the lower temperature of the lower portion is lower than that of the upper portion, so that the blower positioned at the lower end is controlled to operate in the intake mode and the upper positioned blower operates in the exhaust mode, And it operates in the opposite direction when the upper mode operation is performed.

3 is a view showing the structure of a ventilation structure of a seat ventilator according to the present invention in which a first blower 71 is installed inside a cushion 10 and a second blower 72 is installed inside a bag 20 .

The first temperature sensor 61 is disposed adjacent to the first blower 71 and the second temperature sensor 62 is disposed adjacent to the second blower 72.

The first blower 71 and the second blower 72 are connected to each other by the duct 53. The air sucked by the first blower 71 rotates through the duct 73 to the second blower 72 The air blown by the second blower 72 rotates in the opposite direction to the cushion 10 through the duct 73 and the first blower 71 rotates in the opposite direction, .

The controller 80 controls the rotation direction of the first blower 71 and the second blower 72 of the flow passage 70 according to the temperatures of the cushion 10 and the bag 20 measured by the temperature measuring unit 60 Setting.

Here, when the temperature measured by the first temperature sensor 61 is higher than the temperature measured by the second temperature sensor 62, the second blower 72 is rotated to suck air, and the first blower 71 And is rotated in the opposite direction to the second blower 72 to discharge the air.

When the temperature measured by the first temperature sensor 61 is lower than the temperature measured by the second temperature sensor 62, the first blower 71 is rotated to suck air, and the second blower 72 And is rotated in the direction opposite to that of the first blower 71 to discharge air.

When the difference between the temperature values measured by the first temperature sensor 61 and the second temperature sensor 62 is equal to or greater than a preset reference value, the controller 80 sets the rotational speeds of the first blower 71 and the second blower 72 The air intake amount and the emission amount can be increased.

4 is a flowchart showing a seat ventilation method in which a blower according to the present invention operates. Referring to FIG. 4, when a passenger boarded the vehicle, the operation command of the ventilation switch 50 is received (S100).

Upon receiving the operation command, it is confirmed whether the air conditioner is operating (S200). If the air conditioner is operating, it is determined which mode is operated (S300).

When the air conditioner operates in the lower mode, that is, when the air conditioner operates so as to allow wind to flow to the lower end of the user, the cushion blower operates in the intake mode and the back blower operates in the exhaust mode in operation S600.

When the air conditioner operates in the upper mode, that is, when the air conditioner operates so that the wind is directed toward the upper body of the user, the cushion blower operates in the exhaust mode and the back blower operates in the intake mode (S700).

In the modes other than the above mode in which the air conditioner operates only in the upper mode or the lower mode only, the upper and lower temperature sensors measure the temperature (S400), compare the measured temperature differences (S500) The cushion blower operates in the intake mode, and the back blower operates in the exhaust mode (S600).

When the lower end temperature is higher than the upper end temperature, the cushion blower operates in the exhaust mode and the back blower operates in the intake mode (S700).

The first blower 71 and the second blower 72 are connected by a duct 73 to suck or discharge air into the cushion 10 and the bag 20.
