Description

Air Conditioning System for Vehicles {AIR CONDITIONING SYSTEM FOR AUTOMOTIVE VEHICLES}

The present invention relates to a vehicle air conditioner, and more particularly, when the seat cooling and heating device is operated, the "set vehicle interior temperature" of the air conditioner can be automatically reset to match the current vehicle interior temperature in conjunction with this. By constitution, it is possible to reduce the trouble of having to reset the vehicle interior temperature every time the vehicle is started (ON), and therefore, the present invention relates to a vehicle air conditioner that can improve user convenience.

Recently, vehicle air conditioners have been improved by an automatic control method.

The automatic control system air conditioner (hereinafter, abbreviated as "air conditioner") selects "auto mode" with the auto mode switch 3 of the controller 1, as shown in FIG. When the desired " indoor temperature " is set with the temperature control switch 5, optimum data is calculated by comparing the temperature data of the inside and outside of the vehicle sensed by various sensors with the preset “indoor temperature”.

The air conditioner 7, the heater 9, the blower 10, and the various mode doors 12 are automatically controlled based on the calculated data. Therefore, the temperature of the air supplied to the inside of the vehicle, the air volume, the discharge direction, and the like are automatically adjusted according to the temperature conditions outside the inside of the vehicle and the preset "indoor vehicle temperature" (hereinafter referred to as "set vehicle interior temperature"). As a result, the temperature in the vehicle interior is always kept comfortable in accordance with the "set vehicle interior temperature".

On the other hand, the air conditioning apparatus further includes a seat cooling and heating device 20 for heating and cooling the driver's seat and the passenger seat.

The seat cooling and heating device 20 includes a heating wire (not shown) and a ventilation device (not shown) built in the driver's seat and the passenger seat, and operates the seat cooling and heating switch 22 of the controller 1. When ON, the driver's seat and the passenger seat are heated warmly or cool air is supplied to the driver's seat and the passenger seat. Therefore, the driver's seat and the passenger seat are heated in winter, or the driver's seat and the passenger seat are cooled in the summer.

In general, the sheet cooling and heating apparatus 20 may be rapidly cooled and heated, and thus, the sheet cooling and heating apparatus 20 may be used for preheating and precooling the sheet during the initial operation of the air conditioning apparatus.

In addition, the seat cooling and heating device 20, through the seat cooling, heating switch 22 is capable of adjusting the cooling, heating stage. Therefore, the temperature of the sheet can be adjusted in multiple stages according to the temperature conditions inside and outside the vehicle interior. Typically, the number of stages of cooling and heating of the sheet cooling and heating apparatus 20 is generally adjusted to three stages.

However, such a conventional air conditioner has a disadvantage in that the temperature of the set vehicle interior is reset every time through the temperature control switch 5 every time the vehicle is started.

In particular, when the vehicle interior temperature difference when the vehicle is turned off and the vehicle temperature difference when it is ON is severe, it is necessary to reset the "set interior temperature" every time through the temperature control switch (5). There is a disadvantage, and it is pointed out that the problem is very cumbersome and inconvenient to use because of this disadvantage.

That is, the air conditioner, when the start of the vehicle is turned off, stores the "set vehicle interior temperature" information when the start of the vehicle is turned off, and the vehicle is turned on again. Is configured to control the various air conditioning units 7, 9, 10, 12 according to the stored "set vehicle interior temperature" data.

However, since the "stored interior temperature" already stored is set on the basis of the interior temperature when the vehicle is turned off, it is different from the interior temperature when the vehicle is turned on. Deviation occurs.

In particular, in the case of a low temperature in winter or a high temperature in summer, the cabin temperature when the vehicle is turned on is larger than the cabin temperature when the vehicle is turned off. Is generated, the comfort in the vehicle is inevitably deteriorated when the air conditioner is controlled based on the " set vehicle interior temperature " stored when the vehicle is turned off.

Therefore, most drivers, when turning on the air conditioner in the state where the vehicle is turned on, set the "indoor vehicle temperature to match the interior temperature when the vehicle is turned on. ", And every time, many drivers feel trouble and discomfort.

Furthermore, when preheating or precooling the seats of the driver's seat and the passenger seat using the seat cooling and heating device 20 at the initial start of the vehicle, the seat cooling and heating switches 22 must also be operated. There is a problem that the operation of the switch becomes more complicated, and because of this problem, many drivers complain of inconvenience and inconvenience.

The present invention has been made to solve the above-mentioned conventional problems, the object is, by operating the seat cooling, heating device, by configuring so that it can be automatically reset to the "set interior temperature" in connection with the vehicle, It is to provide a vehicle air conditioner that can save the hassle of having to reset the "set indoor temperature" every time the start of the (ON).

Another object of the present invention, by configuring to reduce the hassle of having to reset the "set indoor temperature" every time the vehicle is turned on (ON), for a vehicle that can significantly improve the user's convenience To provide an air conditioner.

In order to achieve the above object, the vehicle air conditioner of the present invention, a controller for controlling each air conditioning unit based on the set indoor temperature set by the user, and a seat cooling, heating device for cooling and heating the driver's seat and passenger seat Including, The seat cooling and heating device in the vehicle air conditioning apparatus that can control the number of cooling and heating stages of the driver's seat and passenger seat in multiple stages, when cooling or heating the driver's seat and passenger seat with the seat cooling, heating device, And a control unit for resetting a preset vehicle interior temperature of the controller in association with cooling and heating of a seat; The controller is characterized in that for controlling each of the air conditioning unit on the basis of the set room temperature reset by the control unit.

Preferably, the first memory unit includes a vehicle interior temperature value set for each stage of heating corresponding to each stage of heating of the seat cooling and heating device; And a second memory unit configured to include room temperature values set for each cooling stage corresponding to each cooling stage of the seat cooling and heating device. The control unit, when the specific cooling and heating stage is selected as the seat cooling and heating unit, sets the room temperature value corresponding to the selected specific cooling and heating stage in the first memory unit or the second memory unit. And detecting and resetting the detected preset vehicle interior temperature value to the preset vehicle interior temperature of the controller.

In addition, the set interior temperature values for each stage of heating built in the first memory unit have a size proportional to the number of heating stages of the seat cooling and heating apparatus, and set the set interior temperature for each stage of cooling embedded in the second memory unit. Values are characterized by having a size inversely proportional to the number of cooling stages of the sheet cooling and heating apparatus.

According to the air conditioner for a vehicle according to the present invention, when the cooling and heating stages of the seat air conditioning and heating device are manipulated, the vehicle is automatically reset to the "set vehicle interior temperature" of the air conditioning device, so that the vehicle is turned on.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a vehicle air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.

First, prior to looking at the features of the vehicle air conditioner according to the present invention, with reference to Figure 2 will be briefly described for the automatic control type air conditioner.

The automatic control system air conditioner selects the "auto mode" with the auto mode switch 3 of the controller 1, and then sets the desired "indoor temperature" with the temperature control switch 5, and the difference detected by the various sensors. The optimum data is calculated by comparing the indoor and outdoor temperature data with a preset " indoor temperature ".

And based on the calculated data, each air conditioning unit (7, 9, 10, 12) is automatically controlled. Therefore, the temperature, the air volume, the discharge direction, and the like of the air supplied to the vehicle interior are automatically adjusted according to the temperature conditions outside the vehicle interior and the "set vehicle interior temperature".

The automatic control system air conditioner further includes a seat cooling and heating device 20 for cooling and heating the driver's seat and the passenger seat.

When the seat cooling and heating device 20 is turned on by operating the seat cooling and heating switch 22 of the controller 1, the seat cooling and heating device 20 warmly heats the driver's seat and the passenger seat or supplies cool air to the driver's seat and the passenger seat. .

Therefore, the driver's seat and the passenger seat are heated in winter, or the driver's seat and the passenger seat are cooled in the summer. In particular, in the initial operation of the air conditioner, the driver's seat and the passenger seat are preheated or precooled before the air conditioner is sufficiently activated.

Typically, the sheet cooling and heating device 20 is capable of adjusting the cooling and heating stages through the sheet cooling and heating switch 22. For example, when the sheet cooling and heating switch 22 is repeatedly pressed and operated, the number of cooling and heating stages of the sheet cooling and heating device 20 is adjusted to three stages according to the number of pressing times.

Next, the features of the air conditioner according to the present invention will be described in detail with reference to FIGS. 2 and 3.

First, referring to FIG. 2, the air conditioning apparatus of the present invention includes a control unit 30.

The control unit 30 includes a microprocessor, and includes a first memory unit 32 and a second memory unit 34.

The first memory unit 32 has built-in " set vehicle interior temperature values " for each " heating stage number " corresponding to each heating stage of the seat cooling and heating apparatus 20. As shown in FIG.

For example, "26 degrees Celsius" corresponding to "single stage", "29 degrees Celsius" corresponding to "two stages", "32 degrees Celsius" corresponding to "three stages" of seat cooling and heating apparatus 20 (High) is built in as "set interior temperature value", respectively.

The second memory unit 34 has a built-in vehicle interior temperature value for each cooling stage corresponding to each cooling stage of the seat cooling and heating apparatus 20.

For example, "22 degrees Celsius" corresponding to the cooling stage number "single stage" of the seat cooling and heating device 20, "20 degrees Celsius" corresponding to "two stages", "17 degrees Celsius" corresponding to "three stages" (Low) is built in as "set interior temperature value", respectively.

On the other hand, when the user turns on the seat cooling / heating device 20 while the user turns on the vehicle, the controller 30 selects a specific cooling / heating stage. The " set vehicle interior temperature value " corresponding to the cooling and heating stages of the "

When the "set indoor temperature value" corresponding to the specific cooling / heating stage is detected, the controller 30 removes the existing "set indoor temperature" already stored in the controller 1, and instead The " set vehicle interior temperature value " detected by the first and second memory units 34 is stored in the controller 1 as the " set vehicle interior temperature " of the air conditioning apparatus.

For example, when the user turns on the vehicle and then selects the seat cooling / heating device 20 as the heating "stage 1," the "setting car" corresponding to the selected heating "stage 1". The room temperature value "and" 26 degreeC "are detected by the first memory unit 32.

And when the "set interior temperature value" (26 degreeC) corresponding to the seat heating "stage 1" is detected, the control part 30 removes the existing "set interior temperature" already stored by the controller 1, Instead of this, the " set vehicle interior temperature value " (26 DEG C) corresponding to the seat heating " stage 1 " is stored in the controller 1 as the " set vehicle interior temperature "

Therefore, when the air conditioner is operated or in operation, the controller 1 controls each of the air conditioners 7 and 9 of the air conditioner based on the "set vehicle interior temperature" (26 ° C) corresponding to the seat heating "stage 1". , 10, 12).

In this way, the air temperature, the air volume, and the wind direction discharged into the vehicle interior are controlled in accordance with the "set vehicle interior temperature" (26 ° C) corresponding to the seat heating "stage 1".

In conclusion, when the air conditioner is operated after the vehicle is turned on, the control unit 30 has the " set cabin temperature " of the air conditioner as the cooling / heating stage of the seat cooling / heating device 20. It is configured to automatically set up in conjunction with.

In particular, most drivers, after turning on the vehicle, preheat and preheat the seat cooling and heating device 20 in accordance with the current vehicle interior temperature. Adjust the temperature bar, if the "set indoor temperature" of the air conditioning unit is automatically set in conjunction with the cooling and heating stages of the seat cooling and heating unit 20, the "set indoor temperature" of the air conditioning unit is also present The price is set appropriately for the vehicle interior temperature.

Therefore, when the air conditioner is operated after the vehicle is turned on, the "set difference temperature" of the air conditioner is not required even if the user does not manually reset the "set car temperature" in accordance with the current room temperature. "Indoor temperature" is automatically reset to the current cabin temperature.

In this way, the user does not need to manually operate the temperature control switch 5 of the controller 1 to reset the "set vehicle interior temperature". As a result, the user's convenience is remarkably improved.

On the other hand, when the controller 30 resets the "set interior temperature" of the air conditioning apparatus according to the number of stages of cooling and heating of the seat cooling and heating apparatus 20, the reset "set interior temperature" is displayed on the display unit 1a. The display unit 1a is controlled to be displayed on the display panel. Therefore, the user is informed that the "set cabin temperature" of the air conditioning apparatus is automatically reset.

In the first memory unit 32 of the control unit 30, the "set vehicle interior temperature value" for each "heating stage" of the seat cooling and heating device 20 is built-in. They have a size proportional to the number of heating stages of the sheet cooling and heating device 20.

This is to allow the "set interior temperature value" to increase in proportion to the heating stage of the seat cooling and heating device 20.

The reason for this configuration is that the lower the temperature in the vehicle interior, the user increases the number of heating stages of the seat cooling and heating apparatus 20. When the heating stage of the seat cooling and heating apparatus 20 is increased in response to the low interior temperature, In order to increase the temperature, the " set vehicle interior temperature " of the air conditioner is also set to be gradually increased in response to the low vehicle interior temperature.

In addition, the second memory unit 34 of the control unit 30 has a built-in vehicle interior temperature value for each of the " cooling stage number " of the seat cooling and heating device 20, and the " set vehicle interior temperature value. "They have a size inversely proportional to the number of cooling stages of the sheet cooling and heating apparatus 20.

This is to allow the "set interior temperature value" to decrease inversely as the number of cooling stages of the seat cooling and heating device 20 increases.

The reason for this configuration is that the higher the temperature in the vehicle interior, the user increases the cooling stage of the seat cooling and heating apparatus 20. When the cooling stage of the seat cooling and heating apparatus 20 is increased in response to the high interior temperature, The higher the temperature, the more the " set interior temperature " of the air conditioner is to be set lower gradually in response to the higher interior temperature.

According to the present invention having such a configuration, when the cooling and heating stages of the seat cooling and heating device 20 is operated, the air conditioning device is automatically reset to the "set cabin temperature" of the air conditioning device, so that the vehicle is turned on. After (ON), when operating the air conditioner, the user does not have to manually reset the "set cabin temperature" to match the current cabin temperature.

In addition, when the air conditioner is operated after the vehicle is turned on, the user does not have to manually reset the "set vehicle interior temperature" to match the current vehicle interior temperature. Each time (ON), the temperature control switch (5) can save the hassle of having to reset the "set indoor temperature" every time.

In addition, since it is possible to reduce the trouble of having to reset the temperature inside the vehicle every time the vehicle is turned on, the user's convenience can be remarkably improved.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.
