There is a manual mechanism, for example, a mechanical valve or a solenoid valve) that is closed before being fastened. Two oil outlets 20 are formed, and a pressure plate 22 is fixed to the rear surface so as to protrude forward by a spring 24 for applying pressure.

In addition, an oil level sensor 26 is attached to the front of each storage space 15 of the case 16 to sense the pressure of the aroma oil or the pressure of water, and transmit the detection signal to the controller 30. On the upper surface of each storage space 15, an oil type recognition chip 28 for detecting the type of oil and transmitting the detection signal to the controller 30 is attached.

Of course, the oil level sensor 26 and the oil type recognition chip 28 are connected to the controller 30 so as to exchange signals.

Accordingly, the aroma oil container 12 having different types is inserted into and fixed in the storage space of the case 16, and the water storage container 14 is inserted into and fixed to the other space, and the outlet portion of each container is fixed to the oil. When it is fixed by being inserted into the outlet 20, the oil type recognition chip 28 recognizes the type of the oil and transmits the signal to the controller 30.

As an example of recognizing the type of oil, there is a method in which a barcode is attached to the aroma oil container 12 and the barcode is read by the oil type recognition chip 28, and the recognition of detecting the aroma of the aroma oil is performed. The method of using a chip for a chip is mentioned.

At this time, the aroma oil container 12 and the water container 14 is a container made of a flexible material that can be shrunk, and is placed on the back of the case 16 to the pressure plate 22 that is pushed by the pressure applying spring 24. It is to be compressed by the bar, the pressure at this time is to be detected by the oil remaining amount sensor 26.

Here, the IMS information signal of the IMS memory is connected to the controller 30 so that the signal can be exchanged. The IMS information signal is a user's desired oil selection, injection nozzle selection, injection time selection, user designation selection, desired humidity.

-Aromatic oils that increase blood pressure

Sage, thyme ....,

-Aromatic oils forbidden for asthma

Majoram, yarrow .....,

There are many other types, but descriptions of those types will be omitted.

Looking at the operating state of the storage means as described above are as follows.

First, the IMS signal of the IMS memory is transmitted to the controller 30 together with the operation switch ON on the control panel 34, and the IMS information (preselected oil selection, injection nozzle selection, injection time) of the IMS memory. Selection, target user designation, desired humidity selection, etc.) is received / analyzed by the controller 30, and the corresponding aromatic oil type is selected / received by comparing with the oil type recognition signal received from the oil type recognition chip 28. The recognition step proceeds.

Alternatively, the aromatherapy system automatically operates according to the IMS information. When the driver excludes the automatic operation, various types of information may be input and transmitted to the controller 30 through the control panel 34.

Next, the mixing space 44 of the mixing / distributing means 42 described below through the oil outlet 20 through the oil outlet 20 of the storage space 15 in which the aromatic oil type is stored. Is discharged.

At the same time, as the aroma oil in the aroma oil container 12 is discharged through the oil outlet 20 by the pressure of the pressure plate 22, the pressure plate 22 pressurizes the aroma oil in the aroma oil container 12. (Aroma oil amount is reduced at the same time the pressure of the pressure plate is reduced) is reduced, the pressure at this time is detected by the remaining oil level sensor 26, the signal is transmitted to the controller (30).

The controller 30 receives the detection signal of the oil remaining amount detecting sensor 26 and compares it with a preset reference pressure. When the controller 30 is below the reference pressure, the controller 30 determines that the remaining amount of oil is exhausted. The display unit 38 of 34 transmits a signal indicating the replacement time.

Here, the mixing / distributing means will be described with reference to FIG. 3 as follows.

The mixing / distributing means 42 is a case structure that is integrally attached to the front surface of the storage means 10. The configuration is that a mixing volume 44 of a predetermined volume is formed therein, and An oil inlet corresponding to the oil outlet 20 is formed at the rear of the mixing space, and a plurality of oil distribution ports 46 are formed at the front of the mixing space 44.

In addition, each of the oil distribution port 46 is provided with a solenoid valve 48 which is subjected to the on / off control of the controller 30, and is installed rotatably in the mixing space 44 is the controller ( It includes a stirring means 50 for driving in accordance with the signal of 30).

In addition, it is further provided with a small motor pump 52 installed in the mixing space 44, driven according to the signal of the controller 30 to guide the mixed aroma oil to the oil distribution port 46.

Looking at the operating state of the mixing / distributing means 42, when the aromatic oil is introduced into the mixing space 44 of the mixing / distributing means 42 from the oil outlet 20 of the storage means 10, the controller ( The small motor pump 52 is driven according to the current signal of 30 so that the aroma oil flows into the oil distributor 46.

In this case, when two or more kinds of the aroma oil are introduced at the same time, the stirring means 50 is driven according to the current signal of the controller 30, and the step of mixing the two kinds of aroma oils with each other may be performed. .

Next, the controller 30 sends a current signal to open the solenoid valve 48 of the oil distribution port 46 that matches the selected one of the injection nozzles of the injection means described later, so that the aroma oil is the oil distribution port ( Through 46).

On the other hand, the case structure applied to the storage means 10 and the mixing distribution means 42 is preferably made of a heat insulating material to insulate the aroma oil from direct sunlight and heat generating means of the vehicle.

Here, the configuration of the injection means 54 with reference to Figure 4 and the oil movement pipe 56 connected to the oil distribution port 46 of the mixing / distributing means 42; An injection nozzle body 60 having a predetermined volume of air space 58 for spraying oil therein; A plurality of injection nozzles 62 attached to the front surface of the injection nozzle body 60; A diaphragm 64 attached to the air space 58 while blocking the outlet of the injection nozzle 62 to vibrate according to a drive signal of the controller 30; It consists of a pressure holding plate 66 is attached to traverse the air space 58 in the transverse direction to maintain the pressure of the injection nozzle (62).

Preferably, the oil movement pipe 56 extending from the injection nozzle body 60 is extended while bending to a desired injection position in the car interior, and the aromatic oil can be injected into a desired indoor location.

Looking at the operating state of the jetting means 54, if the controller 30 sends an operating current signal to the diaphragm 64 of the jetting means 54 to be operated, the standby space 58 of the jetting means 54 Aroma oil introduced into the A) is injected into the room along the injection nozzle 62 by the driving of the diaphragm 64.

After the spraying step of the aroma oil, the step of transmitting a signal to the controller 30 by measuring the indoor concentration of the aroma oil in the oil concentration sensor 68, which can be installed in a certain part of the car interior, The controller 30 controls the vibration speed of the diaphragm 64 of the spraying means 54 according to the sensed aroma concentration of the room.

That is, as the vibration speed of the diaphragm 64 is added or subtracted, the injection amount and the injection speed of the aroma oil injected through the injection nozzle 62 are adjusted.

In more detail, when the concentration of the aromatic oil in the room is greater than or equal to the reference value, the controller 30 drives the oscillation speed of the diaphragm 64 slowly to reduce the injection amount of the aromatic oil that is injected into the room. The speed of 64 is quickly driven to increase or maintain the injection volume.

In this way, by spraying aroma oils of plants with excellent fragrance and containing substances with therapeutic effects into the interior of the vehicle, the mind and body of the driver and passengers are relaxed, Healing the disease will clear the mind and get the stress relief effect, which will also contribute to safe driving.

On the other hand, when the user selects a different aroma oil, and wants to determine the number of injection nozzles (number of injection positions), the injection time, the target user selection, the desired humidity selection differently, by using the control panel 34 The above information is input, and the input information at this time is stored as IMS information in the IMS memory.

In addition, when re-input is not input to the control panel 34 during the reference time, it is preferable to generate an alarm sound in the alarm unit 40 included in the control panel 34.

In addition, when the user or another user inputs the user's information through the control panel 34 and simultaneously selects the desired aroma oil, the selected aroma oil is compared by comparing the user information input by the controller 30 with the selected aroma oil. If it is determined that the oil is harmful to the user's body or spirit and is harmful, it sends a signal to the alarm unit 40 of the control panel 34 so that an alarm sounds, resulting in the selection of aroma oil suitable for the user's body or spirit. It becomes possible.

Referring to FIG. 5A, the operation routine 1 shown in FIG. 5A will be further described as follows.

Operation routine 1 is the case that user information of IMS memory is selected in operation signal analysis.

That is, when the signal is applied by the IMS function of the IMS memory in the operation signal analysis, the IMS setting value is first read. The oil container number is selected by the set value and the mixing and dispensing machine is operated, and the operating nozzle is operated.

The operation setup time is not received here, but it will continue to operate unless there is another input by the user.

The user's state setting controls the oil in the indoor air so as not to exceed the reference value through the predetermined indoor air oil concentration. If it is below the reference value, the injection amount is maintained. If it is above the reference value, the injection amount is decreased.

The pressure in the vessel is then checked to determine the need for oil change and to inform the control panel of basic information (operation time, remaining time, selected oil, operating nozzle position, whether the vessel is replaced, etc.). If the user SW input occurs, the controller switches to operation routine 2 if it is not 'OFF', and if it is 'OFF', it removes the residual oil in the nozzle and oil and shuts down the system.

Referring to FIG. 5B, the operation routine 2 shown in FIG. 5B will be further described as follows.

Operation routine 2 is a case where the user inputs the information directly, activates and displays the previous information stored in the controller, checks whether the oil type has changed while the system is shut down, and reads the oil information. If there is no user input during the reference time, the controller makes a beep and executes the user alarm.

If an input is made within the reference time, the controller accepts the input value and compares the information of the object with the oil to determine the hazards to the object of the oil.

At this time, if there is a hazard, the controller displays the hazard and issues a user alarm with a BEEP sound and waits for another input from the user during the reference time (Hazard display example: Selected oil 'rosemary' (selected oil name) is 'Pregnant woman') '(: Potential use may be harmful)

If there is no input during the reference time, the controller will stop the system until the next operating signal is applied (prohibit the use of potentially harmful oil).

If there is no risk of harm, the set oil begins to be mixed and dispensed through the mixer, dispenser and sprayed through the selected operating nozzle. And if it is determined whether there is an operation time among the input user settings, and if there is no infinite operation, and if there is, control is performed for a reference time. This control controls the indoor air oil concentration determined by the user setting to meet the reference value by comparing it with the actual concentration perceived by the sensor.

The pressure in the vessel is then checked to determine the need for oil change and to inform the control panel of basic information (operation time, remaining time, selected oil, operating nozzle position, whether the vessel is replaced, etc.).

And always check whether the user inputs a new set value and if the new value is input, determine the oil hazard and reflect the operation. In addition, when the operation time is exceeded, a new input is requested to the user through a display, and when a new setting value is input, the hazard possibility operation is performed again.

Here, a humidity control system of the indoor air conditioning system for automobiles according to the present invention will be described.

6 is a flowchart showing an operation routine of the humidity control system, which is not described below in the order of the operation routine.

On operation of the control panel 34, a step of transmitting a signal to the controller 30 by sensing the humidity in the humidity measuring sensor 70 installed in the car interior, the car in a dry weather conditions, such as winter The indoor air is also dry.

Accordingly, when it is determined that the controller 30 is less than the reference humidity, the current signal is transmitted to open the solenoid valve 18 of the oil outlet 20 of the storage space 15 in which the water storage container 14 is stored.

Subsequently, water flows out of the mixing space 44 of the mixing / distributing means 42 through the solenoid valve 18 and at the same time the controller 30 causes the oil distribution port 46 of the mixing / distributing means 42 to 1. A current signal is sent to one or more solenoid valves 18 selected to open.

Next, when the controller 30 sends an operating current signal to the diaphragm 64 of the injector 54 to operate the water, the water introduced into the air space 58 of the injector 54 is the diaphragm ( 64 is injected into the room along the injection nozzle 62 by driving.

In this way, the water is sprayed like a steam by the vibration of the diaphragm 64, to provide a humidification effect to the interior of the car.

In particular, as the water flows along the path through which the aroma oil passes while the method for controlling indoor humidity is in progress, the aroma oil remaining in each path may also be washed.

On the other hand, it will be described in detail with respect to the operation routine 3 with reference to the accompanying Figure 6 as follows.

When the user turns on the system and inputs the desired humidity setting and operation time as input values, the controller recognizes the input and sprays water from the nozzle according to the set value.

At this time, the humidity sensor of the indoor air to determine the humidity of the room compared with the desired humidity value, when the water spray amount is lower when the low, maintain the spray amount when the same, and decrease the spray amount when the high. The control panel also displays the current humidity, operating time and remaining time.

Also, by analyzing the input value input by the user during the operation, if the input value is oil setting or nozzle setting, the operation routine is changed to an aromatherapy routine, and the system is stopped when SW 'OFF'.

At this time, in the spray amount control, the humidity control system is mainly used in winter, when the air in the room escapes to the outside (opening the window) hardly occurs, so the spray amount is adjusted in three steps as in the flowchart. It is desirable to raise the efficiency.

As described above, according to the automotive indoor air conditioning system and control method thereof according to the present invention, by spraying aroma oil containing a therapeutically effective substance and having an excellent aroma to the interior of the vehicle, the mind and body of the driver and passengers It has a stress relief effect that relaxes and clears the mind of the driver.

In addition, the stress relief effect that clears the driver's mind provides the advantage of contributing to the driver's safe driving.

In addition, it is possible to obtain a humidification effect by spraying water during indoor drying.

These effects can eventually contribute greatly to the increase in the commerciality of the vehicle.
