Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a fragrance that has a wake-up effect, etc. to occupants in the cabin of an automobile, especially the driver, when the occupants become drowsy. The present invention relates to an aroma air conditioner.

(Prior Art) As a conventional aroma supply device, for example, one shown in FIG. 1 has been proposed (see Japanese Utility Model Application Publication No. 2-219).

That is, a plurality of aroma supply means are provided in the vehicle interior, and when supplying the aroma, first the first aroma is supplied for a predetermined period of time, and then the second aroma is supplied for a predetermined period of time. By supplying different types of aromas, this prevents sensory numbness caused by smelling the same scent for a long time.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional fragrance supply device, the fragrance is supplied into the vehicle interior for a long time, so if there is a driver and other passengers, this passenger will also be affected. I will smell it. For this reason, although the driver is stimulated by a plurality of fragrances and can effectively prevent drowsiness, other passengers have problems such as the irritating odor being more bothersome and interfering with their rest.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an aromatic air conditioner that can provide a fragrance to the driver while suppressing the fragrance to other passengers.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention provides an air conditioner CLI that can select a plurality of air conditioning modes, a fragrance supply means CL2 that provides fragrance to a driver, and a device other than the driver. The vehicle is configured to include an occupant detecting means CL3 for detecting an occupant, and a controller CL4 for controlling the mode of the air conditioner CLI to perform ventilation according to the detection of the presence or absence of an occupant other than the driver during fragrance supply.

(Function) According to the above configuration, when the presence or absence of an occupant other than the driver is detected by the occupant detection means CL3 when the fragrance is supplied to the driver, if there is an occupant, the air conditioner CL
I can also go into outside air introduction mode at the same time, allowing ventilation. Therefore, the fragrance supplied to the driver is diluted by the ventilation wind and is then discharged outside the room.

(Example) The present invention will be described in detail below.

FIG. 2 is a block diagram showing the basic principle of the first embodiment of the present invention, which includes a manual switch 2 that is operated when the driver feels drowsy, and an occupant detection system that detects the presence or absence of an occupant other than the driver. It has a seat pressure switch as means CL3, and these signals are input to computer 3 as controller CL4. The seat pressure switch 1 is provided, for example, on a passenger seat or a rear seat. On the output side of the computer 3, an aroma supply means 4 (Cl3) and an air conditioner 5 (CLI
) is connected, and the fragrance supply means 4 is operated by the ON signal of the manual switch 2 to generate an awakening fragrance to the driver. At this time, if there is an occupant other than the driver based on the signal from the seat pressure switch 1, the air conditioner 5 is operated in the outside air introduction mode to perform ventilation in conjunction with the aroma supply function.

FIG. 3 is a diagram showing the installation state of the aroma supply means and the configuration of the air conditioner. The aroma supply means 4 is installed in the steering section 30, and the aroma supply means 4 is installed in the steering section 30 so that the aroma directly reaches the nostrils of the driver A at the driver's seat 31. It has become.

In addition, the air conditioner 5 has intake ports 11° and 12 on the outside air side and the indoor side.
is provided together with the intake door 13, and a proa fan 14, an evaporator 15, an air mix door 16, and a heater core 17 are arranged downstream of these. Then, the cold air, warm air, or a mixture of both that has passed through the air mix door 16 and the heater core 17 is sent to the defroster outlet by controlling the opening and closing of the differential door 18, or to the ventilator outlet by controlling the opening and closing of the vent door 19, and to the ventilator outlet by controlling the opening and closing of the vent door 19. It is configured to be guided to each lift outlet by opening/closing control.

Here, in the blowout mode (multiple air conditioning states) that is turned on with the mode control lever, the vent mode,
In the case of the differential mode, the air from each outlet flows above the fragrance. Furthermore, when the signal from the computer 3 is output to the aroma supply means 4, if the air conditioner 5 is not in the ventilation state of introducing outside air, the intake door 13 opens the outside air inlet 11, and the motor 21 of the proa fan 14 is driven. This is the circuit configuration.

Next, the operation of this embodiment will be explained using the flow chart of FIG.

First, in step S1, when the driver feels drowsy and turns on the manual switch, the process proceeds to step S2 to check the state of the air conditioner. Then, if it is operating, the process advances to step S3 to check the state of the blowout mode, and if it is the outside air introduction mode, the process advances to step S4 to detect the presence or absence of an occupant. In addition, in a mode other than air conditioning non-operation and outside air introduction, the air conditioning operation state of the outside air introduction mode is forcibly set in step S5. Next, the process proceeds from step S4 to step S6 to check whether there is any occupant other than the driver. If there is only the driver, the process proceeds to step S7 to start supplying fragrance and at the same time start time counting. Then, in Step S8, the fragrance is directly supplied to the driver's nostrils for a predetermined period of time TF to stimulate the driver's nostrils, and the driver's drowsiness is avoided by this awakening effect.Then, the process proceeds to Step S9 and the fragrance supply is stopped. , clear the time. After the aroma is supplied, the process proceeds to step 510, where the air conditioner is activated to start ventilation in the outside air introduction mode, activated again to start ventilation in the outside air introduction mode, and time is counted again. Then, in step S11, the air is ventilated for a longer predetermined time of 120 to exhaust the fragrance from the vehicle interior, and then the process proceeds to step S12, where the ventilation is stopped and the time is cleared and the process ends.

On the other hand, if there is an occupant other than the driver, step S6
Proceeding to step 813, at the same time as the aroma supply is started, ventilation is also started in the outside air introduction mode, and time counting for both is started.

Then, in step S14, fragrance and ventilation are performed simultaneously for a predetermined time TF, and in step S15, fragrance is stopped.

Therefore, if the ventilation is in vent mode at this time, see Figure 5 (
As shown in a), the wind a blown out from the ventilation outlet 32 flows upward inside the vehicle compartment. Therefore, the aroma from the aroma supply means 4 of the steering section 30 is delivered to the driver's seat 3 without being obstructed by the ventilation wind a.
A, thus providing a wake-up effect to driver A as described above.

In addition, the aroma is diluted by the supplied direct ventilation air a, and is carried to the upper part of the rear inside the passenger compartment 33, and is immediately discharged from the exhaust port 34 to the outside of the passenger compartment. For this reason, it is suppressed from supplying the fragrance and stimulating the passenger B sitting in the rear seat 35.Then, after the fragrance is stopped, the process proceeds to step S16.
In step S12, only ventilation is continued to completely remove the scent inside the vehicle compartment 33, and in step S12, ventilation is also stopped.
It ends with a stubble.

In addition, in the case of blowout mode or differential mode, please refer to Figure 5 (b).
As shown in ), outside air a is blown out from the defroster outlet 36, and the wind a flows upward inside the vehicle compartment 33. Therefore, fragrance and ventilation can be performed at the same time as described above, and stimulation to occupants B other than driver A is suppressed. On the other hand, in foot mode (
Wind a from the foot outlet 37 below the fragrance as shown in C).
will blow out in the direction of driver A, blocking the aroma passage. Therefore, if fragrance and ventilation are performed simultaneously in this mode, it will be difficult to sufficiently supply fragrance to driver A, and in this respect, it is suitable when only driver A is present and ventilation is performed after fragrance.

Furthermore, the operation of another embodiment of the present invention will be explained using the flowchart of FIG.

This embodiment considers opening and closing of windows for ventilation of the vehicle interior. In addition, when ventilating the vehicle, consideration is given to the pollution state of the air outside the vehicle interior, and the vehicle interior is always ventilated with fresh outside air to maintain a good atmosphere inside the vehicle interior.

Therefore, when the manual switch is turned on in step S20,
Proceeding to step S21, the open state of the window is detected, and if the open state of the window is confirmed in step S22, the process proceeds to step 32B, and if the ventilation capacity is sufficient to exhaust the scent-containing interior air to the outside of the vehicle within a predetermined time, the process proceeds to step S24. S25, the process advances to step S26. The ventilation capacity is detected, for example, by detecting the vertical position of the window panel. Then, the predetermined time TF
A fragrance is supplied to the driver between the windows and natural ventilation is provided through the window.
Even if there is a passenger other than the driver, stimulation to the passenger can be suppressed. Therefore, the air conditioner 5 is not operated unnecessarily, and fuel efficiency can be improved.

In addition, if the window is opened or ventilation is insufficient, step S27
Then, the air conditioner 5 is set to the outside air introduction mode.

If the window is closed in step S22, the process proceeds to step 328, and if the air conditioner 5 is inactive, the process proceeds to step S29. If the air conditioner is operating, the process advances from step 528 to step S29. Under these conditions, the air conditioner W5 is newly activated to provide ventilation, the air pollution degree outside the vehicle is detected in step S29, and the process proceeds to step 531, and if the pollution degree is "or lower than the allowable value 0.0, the process proceeds to step S32. to set the outside air introduction mode. Then, step 333, step S34,
Proceeding to step S35, similarly to FIG. 3, an occupant other than the driver is detected, and if an occupant is present, ventilation is performed at the same time as fragrance.

On the other hand, if the pollution level 0 exceeds the allowable value OP, the process proceeds from step S31 to step S36, step S37, and step 538, and the fragrance is supplied regardless of the presence or absence of the driver. Then, in step S39, the degree of contamination is checked to be 0, and when the degree of contamination has decreased to the allowable value O1 or less, the process proceeds to step S4.
0. Proceed to step S41 to promptly ventilate the interior of the vehicle and remove the scent. Therefore, pollution of the air inside the vehicle can be prevented.

Note that this invention is not limited to the above embodiments.

For example, the fragrance supply means may be started automatically when the occupant is detected to be dozing off by eye point detection or the like. The aroma is not limited to a stimulant effect, but may also be one that relieves fatigue and tension. Additionally, a vent outlet structure that creates a specific mode may be used as a means of not supplying fragrance to occupants other than the driver.

[Effects of the Invention] As is clear from the above, according to the present invention, it is possible to apply a sufficient fragrance to the driver, and at the same time, it is possible to suppress the fragrance to other occupants. Therefore, it is possible to suppress unnecessary fragrance to those other than the driver and improve the comfort of the entire vehicle interior.
