Description

[Detailed description of the invention]

[Object of the Invention] (Industrial Field of Application) The present invention relates to a device for purifying the air inside a vehicle, and particularly to a device for cleaning the air inside a vehicle that has been contaminated by smoking. (Prior Art) Conventionally, for example, when the air inside a vehicle becomes contaminated with cigarette smoke, the side windows are lowered, the roof panel is opened, or an air cleaner is operated. The side window glasses are opened and closed electrically in response to steering wheel drive or switch operation, and the roof panel on the vehicle is opened and closed by a manually operated handle, as disclosed in Japanese Patent Application No. 56-128044, for example. In addition, there are devices in which the opening/closing mechanism is electrically driven and the opening/closing drive is instructed by operating a switch. In any case, the side window glass or roof panel is driven by the driver's judgment and operation of the steering wheel or switch. When equipped with an air cleaner, a proposal to detect indoor smoke with a smoke sensor and drive the cleaner;
A device that activates an air cleaner by detecting the drawer of an ashtray with a switch (Japanese Utility Model Publication No. 147058/1983), and a cigarette lighter (electrical heat generating lighter)
There is an idea (Japanese Utility Model Publication No. 53-25043) that detects the setting of the air cleaner by detecting the energization of a resistor connected thereto, and then energizes the air cleaner for a predetermined period of time. (Problems to be Solved by the Invention) However, in the conventional example, the smoke sensor combines a special resistance element or semiconductor element with a high-gain amplifier, and the electrical processing circuit is complicated and expensive. There is also the problem that the operation settings are difficult, and the sensor output fluctuates depending on the stagnation and fluctuation of the indoor air, causing the air cleaner to repeatedly stop and stop in a short period of time. In the conventional examples and the above, there is virtually no such repeated driving/stopping of the air cleaner, but in both of these conventional examples, the air cleaner is only automatically driven, and the dirty air is immediately removed. Exhaust and fresh air are not introduced. The present invention aims to reduce the burden on the driver for air purification during smoking, stabilize the purification operation, and introduce as much fresh air into the room as possible. [Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the purification device of the present invention includes an electric opening/closing means for opening and closing a window of a vehicle; circuit; an air cleaner that purifies the air inside the vehicle; an air cleaner energizing means; an exterior condition sensor that detects the environment outside the vehicle related to the suitability of opening windows; an interior condition sensor that detects whether a smoking aid inside the vehicle is used; Window opening control means for instructing the electric energizing circuit to open the window when the smoking aid is in use when the environmental condition outside the vehicle is suitable for opening the window in response to the state detection of the vehicle exterior condition sensor and the vehicle interior condition sensor; and an air cleaner drive that instructs the air cleaner biasing means to drive when the smoking aid is in use when the vehicle exterior environmental condition is inappropriate for opening the window, in response to the state detection of the vehicle exterior condition sensor and the vehicle interior condition sensor. (Operation) When smoking inside the vehicle when the external environment of the vehicle is suitable for opening the windows, the external condition sensor detects the external environment suitable for opening the windows, and the internal condition sensor detects the smoking aid. When use is detected, the window opening control means instructs the electric energizing circuit to open the window, and the electric energizing circuit electrically energizes the electric opening/closing means to open, thereby opening the window of the vehicle.
This allows the smoky air inside the car to exit the car, and fresh air from outside the car to enter the car, making the air inside the car cleaner. If you smoke inside the vehicle when the outside environment of the vehicle makes it inappropriate to open the windows, that is, when the outside condition sensor detects the outside environment where it is not appropriate to open the windows and the inside condition sensor detects the use of a smoking aid, the air cleaner drive control is activated. The means instructs the air cleaner energizing means to operate, and the air cleaner is operated, thereby purifying the air contaminated with smoke in the vehicle interior. Therefore, according to the present invention, the driver's burden is reduced because the window opens or the air cleaner operates automatically in conjunction with smoking. The detection of smoking is the detection of the use/non-use state of the smoking aid, and this is a stable binary value, so the air purification operation is stable. Furthermore, since windows are automatically opened as much as possible, there are many opportunities for fresh air to enter the room, and as much natural fresh air as possible is introduced. Although it is best to open the windows rather than relying solely on air cleaners to purify the smoke-contaminated interior air, it is also best to use smoke detection means or means for detecting the use/non-use of smoking aids. The purification operation that opens and closes the windows according to the detection status of the vehicle can affect the comfort inside the vehicle in other ways, such as opening the window when it is raining or opening the window when the outside temperature is extremely low. However, in the present invention, the windows are opened when the outside environment is good, and when the outside environment is bad, the air cleaner is operated without opening the windows to take in as much fresh air as possible. This prevents incidental deterioration of the indoor environment, such as moisture inside the car and a drop in temperature. Therefore, according to the present invention, the indoor air becomes more comfortable than in the conventional example. Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings. (Embodiment) FIG. 1 shows an outline of an embodiment of the present invention. A roof panel 20 is attached to a roof 11 of a vehicle 10 so as to be tiltable and slidable. The vehicle 10 is equipped with an outside temperature sensor 31, an outside air humidity sensor 32, an inside temperature (room temperature) sensor 33, ashtray drawer detection switches 34 ₁ to 34 ₄ , and a direct sunlight sensor 35 as environmental sensors. It is connected to an electrical control unit 40. Note that the humidity sensor 32 is mounted at a position where water will adhere when the bonnet gets wet. 36 is an air conditioner, 37
is the air cleaner, M _W is the wiper motor,
These are also connected to unit 40. FIG. 2 shows an electric opening/closing positioning mechanism for tilting and sliding the panel 20. The roof panel 20 is pivotally connected to a carriage 61 by a hinge 60 and supported by one end of a dogleg-shaped lift link 62. A shoe 63 is coupled to the other end of the lift link 62, and the shoe 63 is guided by a guide member on the carriage 61 so as to be movable in the horizontal direction. A threaded rod connected to the tilt motor M _c is screwed into the shoe 63 . A pin is set up in the center of the lift link 62, and this pin engages with the guide groove 64. When the motor M _c reverses, the shoe 63 moves to the right and the lift link 62 moves to the right and rotates counterclockwise to close the roof panel 20 (tilt close). When the switch 63 closes the limit switch SW _c1 , the roof panel 20 completely closes the opening of the roof 11. Just before the intermediate pin of the lift link 62 reaches the upper end of the groove 64, the shoe 63 closes the limit switch _SWc2 . At this time, the panel 20 is fully tilted (as shown by the solid line in FIG. 2).
When the carriage 61 is in _the raised position shown in _FIG .
It is movable left and right along a guide 65. When the carriage 61 is moved to the left until SW _u2 is closed, the carriage 61 moves to the second guide 66.
It can descend to The carriage 61 is supported by a second lift link 67 having a substantially inverted Z shape. One end of the lift link 67 supports the carriage 61, a second shoe 68 is coupled to the other end, and a pin approximately in the middle of the link 67 engages with a second guide groove 69. A lifting motor M _ud is connected to a threaded rod screwed into the shoe 68 . When the motor M _ud reverses, the shoe 68 moves to the left and the lift link 6
7 rotates clockwise while moving to the left and retreats below the second guide 66. When the motor M _ud rotates forward, the shoe 68 moves to the right, the lift link 67 moves to the right and rotates clockwise, and the second
exits above the guide 66. The carriage 61 is driven left and right along a guide 65 or 66 by a slide drive wire 70. The wire 70 is driven by a slide motor _Ms. With the above configuration, the roof panel 20
As shown in Figures 3g to 3g, it can be set to any angle (tilt) and opening (slide) from a fully closed state to a fully open state. As will be described later, in this embodiment, in both the automatic opening/closing control and the automatic opening/closing drive by manual switch operation, the roof panel 20 is fully closed (FIG. 3a), tilted and partially opened (FIG. 3b), Tilt fully open (Figure 3c), slide 1/3 open (Figure 3b), slide half open (Figure 3e)
), slide 2/3 open and slide fully open (3rd g
Only the seven states shown in Figure) can be set. The direct sunlight sensor 35 is installed horizontally on the roof 11, as shown in FIG. 4a. As shown in FIG. 4d, the sensor 35 has four sides 35c, 35d, 35 surrounding the photo sensor 35a.
It has a light-shielding plate formed with numbers e and 35f. As shown in Fig. 4b, α is the critical incidence angle of sunlight at which the direct sunlight passing through the roof opening does not hit the head of the occupant in the rear seat when receiving sunlight from the front, and when receiving sunlight from the rear β is the critical incident angle of sunlight at which direct sunlight does not shine on the head of the passenger in the front seat, and as shown in Fig. Let θ be the critical incident angle at which no light hits,
When the critical incident angle at which direct sunlight does not hit the left seat occupant when receiving sunlight from the right side is γ,
The inclinations of the sides 35c to 35f are set so that the photo sensor 35a receives direct sunlight when the incident angle exceeds each of α, β, γ, and θ, and does not receive direct sunlight when the incident angle does not exceed α, β, γ, and θ. 4
As shown in figure f, they are set to α, θ, β, and γ, respectively. As a result, when the incident angle of sunlight exceeds α, β, γ or θ, the photo sensor 35a
detects direct sunlight, and as described later, the roof panel 20 is tilted fully open (FIG. 3c) to block the direct sunlight, and the photo sensor 35a
If no direct light is detected, the slide is opened when other conditions for the slide to open (FIGS. 3d to 3g) are satisfied. FIG. 5 shows the configuration of the electric control unit 40.

【table】

[Table] The microprocessor MPU reads the opening and closing of k ₁₁ to _{k 55} at a predetermined timing, and then reads the opening and closing of sensors 31 to 3.
It sequentially A/D converts the detected values of 3 and reads the digital data, and then refers to the binary output of ₄₇₅ , the signal level of input ports _A0 , _V1 to _V3 , and the contents of the output register (flag). Then, the opening/closing control of the roof panel 20, the driving/stopping of the air cleaner 37, and the driving/stopping of the air conditioner 36 are performed in accordance with the set program. FIG. 6a shows the control operation of the microprocessor MPU. When the microprocessor MPU is powered on, it initializes by setting all output ports to non-driving levels and clearing its internal register (RAM) memory.As a step in this initialization, the roof panel 20 positioning status is read and set in a register (flag register). That is, the positioning status is read as shown in Table 2 below.

〔Effect of the invention〕

As described above, according to the on-vehicle air purifying device of the present invention, the driver's burden is reduced because the window opening or air cleaner operation is automatically performed in conjunction with smoking. The detection of smoking is the detection of the use/non-use state of the smoking aid, and this is a stable binary value, so the air purification operation is stable. Furthermore, since windows are automatically opened as much as possible, there are many opportunities for fresh air to enter the room, and as much natural fresh air as possible is introduced. Although it is best to open the windows rather than relying solely on air cleaners to purify the smoke-contaminated interior air, it is also best to use smoke detection means or means for detecting the use/non-use of smoking aids. The purification operation that opens and closes the windows according to the detection status of the vehicle can affect the comfort inside the vehicle in other ways, such as opening the window when it is raining or opening the window when the outside temperature is extremely low. However, in the present invention, the windows are opened when the outside environment is good, and when the outside environment is bad, the air cleaner is operated without opening the windows to take in as much fresh air as possible. This prevents incidental deterioration of the indoor environment, such as moisture inside the car and a drop in temperature. Therefore, according to the present invention, the indoor air becomes more comfortable than in the conventional example.
