Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a device for creating a comfortable space in a car interior using various sensors, an air conditioner, an air purifier, and a scent generator.

[Prior art]

Traditionally, creating a comfortable space inside a car involves controlling temperature and humidity using an air conditioner, removing dust and deodorizing using an air purifier, and decorating and decorating the space with fragrance using a scent generator.
It is used for its effects such as deodorizing.

[Problem to be solved by the invention]

However, each piece of equipment was installed to utilize its individual function, and there was no interrelationship with each other. Further, the operation itself was operated independently by each individual operation by the driver and the like. Here, operating each device individually and operating them independently is not only cumbersome for the driver and hinders driving, but each device also causes problems such as the generation of odors when starting the air conditioner, and the air pollution. It has problems such as the slow-acting nature of the purifier and the persistence of scent due to the use of a scent generator. Generally speaking, the scent concentration and the change in human olfactory sense over time when a scent is continuously generated are as shown in Figure 5$10.
Despite the increase in scent concentration, the odor intensity (strength of perceiving the scent) increases once and then immediately decreases. Moreover, FIG. 11 shows the fluctuation of the olfactory threshold (the lowest concentration at which a scent can be perceived) as a function of the scent concentration and time. In other words, under the same environment, the human olfactory sense becomes accustomed to the scent, or fatigue occurs, resulting in an increase in the olfactory threshold and a certain scent concentration (the intersection of the curve indicating the olfactory threshold and the curve indicating the scent concentration). Above that, you won't be able to sense the scent. This means, for example, that if a conventional military-grade volatile scent generator is placed in the passenger compartment of the vehicle, the scent will be felt when entering the vehicle, but as time passes, the scent will become weaker. Or, this is what we normally experience by not being able to perceive scents as much. Furthermore, when trying to effectively utilize the functions of each device,
This is not a desirable situation because the driver or the like has to make extra judgment and attention in addition to driving the car. The present invention has been made in order to solve the above problems, and its purpose is to provide a comprehensive comfortable space creation device in the interior of a car that utilizes the synergistic effect of the interlocking effects of each device. It is to provide.

[Means to solve the problem]

The invention for solving the above problems includes a temperature/humidity adjusting means for adjusting the temperature and humidity inside the vehicle interior, an air purifying means for purifying the air inside the vehicle interior, and a temperature/humidity adjusting means for regulating the temperature and humidity inside the vehicle interior.

To quickly create a comfortable space in the interior of an automobile by effectively utilizing the characteristic effects of a humidity regulating means, an air purifying means, and a scent generating means.

【Example】

The present invention will be described below based on specific examples. FIG. 1 is an explanatory diagram showing an example of the arrangement of each sensor and each device constituting a comfortable space creation device in an automobile. The sensors include a temperature sensor 21 that functions as a heat load sensor, a smoke sensor 22 that detects cigarette smoke inside the vehicle when smoking and a cleanliness sensor that detects odors such as NOx and SOx in the outside air when outside air is introduced. The outside air device sensor 23 detects the air, and each device includes an air conditioner 31 that acts as a temperature/humidity control means, a fan 31a of the air conditioner 31, an air purifier 32 that acts as an air purifying means, and a scent generator 33 that acts as a scent generating means. is installed. FIG. 2 is a block diagram showing the electrical configuration of the comfortable space creation device that controls each sensor and each device shown in FIG. 1. Reference numeral 10 denotes a microcomputer constituting a control means, including a CPU II as a central processing element, a ROM 12 that stores a plurality of control programs for controlling each device, and a ROM 12 that stores conditions such as temperature and outside air equipment. It consists of RAM 13 and interfaces 14 and 15. Then, via the interface 14, the temperature sensor 21, the smoke sensor 22, the outside air device sensor 23, and the air conditioner 3
1. Manual signal 24 input by manual switch activation of each device such as air purifier 32 and scent generator 33
is input to the CPU 11 which implements mode determining means. Then, an output signal from the CPU II is outputted to the air conditioner 31, air purifier 32, and fragrance generator 33 via the interface 15. Next, its effect will be explained. The control system for the comfortable space creation device during cigarette smoking will be described with reference to the program shown in the time chart of FIG. When the smoke sensor 22 inside the vehicle detects cigarette smoke, the air purifier 32 first increases the air flow rate to 120 m'/
At the same time, the fragrance generator 33 generates fragrance intermittently (every 0.5 minutes). this is,
This is to suppress the increase in scent concentration in the vehicle interior by using the air purifier 32 in combination, and to generate a scent corresponding to cigarette smoke. The fragrance generator 33 has a main body 34 as shown in FIG.
, an injection shaft 35 provided on its main body 34, and a drive motor (
The drive roller 36 is rotated forward and backward by a path shown in the figure), and phototubes S, S, S, which detect the insertion position of the scent card 400 inserted into the main body 34 of the scent generator 33. FIG. 5 is a partially broken perspective view for explaining the structure of the scent card 40. The filled aromatic agent 43 and the injection shaft 35 of the scent generator 33 are connected to the holding window 44 of the scent card 40
It consists of an injection pipe 46 through which injection is performed by pushing an injection plate 45 from above. As for its operation, first, when the phototube S detects that the scent card 40 has been inserted into the main body 34 of the scent generator 33, the drive roller 36 moves the scent card 40 to the skewer detected by the phototube S2. sent to the location. When an activation signal is input to the scent generator 33, the scent card 40 is sent by the drive roller 36 to the final position where it is detected by the phototube S, and the scent gas 41 filled in the aromatic agent 43 is ejected from the injection tube 46. A fixed amount of scent gas 41 is injected corresponding to the residence time of the scent card 40 at the final position detected by the phototube S. Incidentally, the scent-generating components of the scented gas 41 are components that can be adsorbed and treated with an adsorbent or deodorizer (path shown in the figure) in the air purifier 32.
Performance balance (compatibility) shall be considered. Furthermore, in the program shown in the time chart of FIG. 3, if the air conditioner 31 is not operating at that time, only the fan 31a in the air conditioner 31 is operated, and together with the circulating air of the air purifier 32, the air is Increase circulation efficiency. Then, after one minute has passed, the air purifier 32
260 m"/H, and all devices stop operating after 2 minutes. The program operating time and the operating mode of each device shown in this time chart are based on the cigarette smoke sensor 22. It is determined by the smoke detection sensitivity of the sensor, the type of scent of the scent generator 33, the intensity of the scent generated at one time from the scent generator 33, and the volume of the interior space of the vehicle.By performing such control, As shown in Figure 6, a characteristic diagram showing the feeling (comfort) of the vehicle interior was obtained based on the intensity of cigarette odor in the vehicle interior and time. The graph shows the case where the duration is 4 minutes, and as can be seen from this characteristic diagram, the intensity of the cigarette odor in the vehicle interior increases with the smoking time, and gradually weakens when smoking is stopped. In the case of no control, the cigarette odor intensity is the strongest, and even if you stop smoking, the cigarette odor intensity does not weaken easily.And when all devices are controlled under the same conditions, the cigarette odor intensity is the strongest. The odor intensity is weak and when you stop smoking, the cigarette odor intensity quickly approaches zero.
It can be seen that when only the air cleaner 32 is controlled, an intermediate value in the characteristic diagram for the above case is taken. Next, the t+ control system of the comfortable space creation device when the air conditioner 31 is started will be described with reference to the program shown in the time chart of FIG. Turn on the manual switch of the air conditioner 31 to operate the air conditioner 31. The air conditioner 31 detects the temperature inside and outside the vehicle by the temperature sensor 21, and is driven to quickly bring the temperature and humidity inside the vehicle to comfortable temperature and humidity. At the same time, the air purifier 32 is operated in the H1 state with an air flow rate of 120 m''/H, and at the same time, the fragrance generator 33 generates fragrance for a certain period of time. Then, 0.5 minutes after the manual switch of the air conditioner 31 is turned on. After the elapsed time, the air purifier 32 increases the air flow rate to 60 m'/
The air purifier 32 is changed to the Lo state of H, and after 1 minute has passed, the air purifier 32
will be stopped. This program uses the fragrance generator 33 to emit a fragrance for a certain period of time in response to a bad odor when the air conditioner 31 is started.
That is, by generating a certain amount, the odor is weakened and the air purifier 32 quickly makes it odorless. Further, the synergistic effect of increasing the temperature control effect of the air conditioner 31 due to the circulating air of the air purifier 32 occurs. Incidentally, since a bad odor is generated only when the air conditioner 31 is started, the air purifier 32 and scent generator 33 are not operated after one minute has passed since the manual switch of the air conditioner 31 was turned on. Next, the control system of the comfortable space creation device when the scent generator 33 is used will be described with reference to the program shown in the time chart of FIG. When the manual switch of the scent generator 33 is turned on and the scent is generated from the scent generator 33 for a certain period of time, that is, in a fixed amount, the air purifier 32 simultaneously increases the air flow rate to 120 m'/
After 0.5 minutes have passed since the manual switch of the fragrance generator 33 was turned on, the air purifier 32 is changed to the Lo state with an air flow rate of 60 m'/H, and after 1 minute has passed, the air purifier 32 is operated in the Hi state. Purifier 32 is stopped. and,
Simultaneously with the operation of the air purifier 32, the fan 31a of the air conditioner 31 is activated, and the circulating air quickly decorates the interior space of the vehicle with fragrance.
Due to the adsorption effect on the adsorbent (not shown) inside the vehicle, you can always enjoy a fresh scent whenever you want it, and the scent will not remain in the vehicle interior for any length of time, so even if you change the type of scent, the mixed scent will not change. It produces a negative effect. Here, in the control system of the above-mentioned comfortable space creation device, if it is necessary to feel the scent for a long time, the scent generator 33 generates the scent intermittently, and the scent inside the vehicle is By suppressing the increase in concentration by using the air purifier 32 in combination, as shown in FIG. 9, it is possible to suppress the increase in the olfactory threshold, and it is possible to always feel the scent. This time program for intermittently generating scent is determined by the type of scent of the scent generator 33, the amount of scent generated from the scent generator 33 at one time, and the volume of the vehicle interior space. Next, in the control system of the above-mentioned comfortable space creation device, the operation when outside air is introduced will be described. When the installed outside air odor sensor 23 detects odors such as NOx and SOx in the outside air, the outside air introduction switching device (not shown) is switched to inside air circulation, thereby creating a comfortable space creation device for smoking cigarettes as shown in Fig. 3. Similarly to the program shown in the time chart of the control system, by controlling the air conditioner 31, air purifier 32, and scent generator 33, the smell of outside air when outside air is introduced is quickly converted into a comfortable space inside the vehicle. . Furthermore, in FIGS. 7 and 8, even when the air conditioner 31 is operating or only the fan 31a of the air conditioner 31 is operating,
When the outside air odor sensor 23 detects that the outside air is dirty, the outside air introduction switching device (not shown) is switched to inside air circulation, and the program shown in the time chart of the control system of the comfortable space creation device is executed. is executed. The installation and purchase of the air purifier 32 and scent generator 33 that constitute the comfortable space creation device of the present invention is not limited to that shown in FIG.
For example, the air purifier 32 may be installed on the ceiling or at the front. Also, the air purifier 32 is the air conditioner 31
It may also be incorporated into. The scent generator 33 may also be integrated into the air purifier 32 and not separated from the air purifier 32, or may be incorporated into the air conditioner 31. Furthermore, air conditioner 3
The air conditioner 1 is not limited to an automatic air conditioner whose operation is controlled by the temperature sensor 21, but may be a manual air conditioner, and the air purifier 32 may also be a manual air conditioner. Also, at this time, the CPU that achieves the mode determination means
I is the manual signal 2 of those manual switches.
4 is input.

【Effect of the invention】

Since the present invention is configured as described above, it is possible to make use of the characteristic actions of each of the devices that achieve each means, to make them related to each other, and to interlock them so as to compensate for their weak points.
Therefore, it is possible to more effectively and quickly create a comfortable space within the vehicle interior, which has a great practical effect.
