Abstract

PURPOSE:To smoothly discharge the smoke of tobacco to the ouside by installing a switching means between the discharge of outside air and the introduction of outside air, in affiliation, onto a plurality of ventilaing ducts and operating the residual ducts to the outside-air inroduction when a part of the ducts are operated to the inside-air discharge side. CONSTITUTION:On the car-interior ceiling part of a passenger car, ventilating ducts 1 are installed at the positions corresponding to the positions of passengers' seats, and the ducts 1 communicate to an outside-air introducing blower 2 on the back side of an instrument panel and an inside-air discharging blower 3 through air hoses 4 and 5. The valves 6-13 for the intermission of ventilation are installed midway into the hoses 4 and 5. Therefore, when a driver at the right lower position begins smoking, only the valve 13 of the inside-air discharging hose 5 communicating to the duct 1 is opened, and other valves 10-12 are closed, and only the valve 9 of the outside-air introducing hose 4 communicating to the duct 1 is closed, and other valves 6-8 are opened, and thus rapid smoke- discharged is permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ventilation system for a vehicle that can individually ventilate the vicinity of seats on each side of a passenger.

[Prior Art] In general, a method for ventilating the interior of a vehicle, particularly a passenger car, involves taking in outside air from the front of a single compartment, passing it through the interior of the vehicle, and then discharging it to the outside of the vehicle from the rear of the vehicle.

Therefore, if the passenger in the front seat smokes, the passenger in the rear seat will naturally be exposed to the smoke, and the passenger in the seat next to him will also be bothered by the smoke. Under conditions where outside air intake is stopped and internal air circulation air conditioning is activated, the harm caused by one person's smoking is equally distributed to other passengers, and recent research reports show that the harmful components contained in cigarette smoke Even in light of experimental data showing that the quality and quantity of smoldering smoke from the tip of a cigarette is much larger than that from the mouthpiece, conventional methods of ventilation inside the vehicle It is desirable that it be revised.

[Object of the Invention] The present invention provides for the purpose of individually cleaning the vicinity of each passenger so that when the interior of a vehicle, particularly a passenger car, is partially contaminated with cigarette smoke, etc., the dirty air does not diffuse into the interior of the vehicle. The purpose is to provide a device for ventilation.

[Configuration of the Invention] The personal ventilation device for a vehicle of the present invention includes a plurality of ventilation ducts attached with switching means for discharging inside air and introducing outside air;
It consists of a combination of an outside air introduction blower and an inside air exhaust blower that are connected to each of these ducts, so that when some of the ventilation ducts work toward the inside air exhaust side, the remaining ventilation ducts work toward the outside air introduction side. It will be configured.

According to a preferred embodiment of the present invention, the plurality of ventilation ducts are distributed and provided in a ceiling portion of the vehicle interior corresponding to the seating position of each passenger, and a switching means for discharging inside air and introducing outside air from the ducts is provided. consists of a combination of smoke sensors and internal/external air switching valves or dampers attached to each of the ducts, and an electronic control circuit for switching and operating each of the valves based on signals from the sensor υ.

[Effects of the Invention] The personal ventilation system for a vehicle having the above configuration has the following effects.

b) A ventilation duct dedicated to each seat is installed in the ceiling above each passenger's seating position. For example, when one passenger smokes, the duct for this seat is operated to ventilate the smoke to other passengers. However, in this case, by setting up an interlocking relationship so that all the ducts in the remaining passenger seats work toward the outside air intake side, smoke can be discharged more reliably and quickly.

[Example] Next, a personal ventilation system for a vehicle according to the present invention will be described based on an example shown in the drawings.

FIG. 1 is a perspective view of the device of the present invention installed in a passenger car, and there are ventilation ducts 1 on the ceiling of the vehicle interior at locations corresponding to the seating positions of each passenger, in this case in the front. A total of four ducts are installed, two each in the rear seats, and each duct 1 is connected to a blower 2 for introducing outside air installed on the back of the instrument panel inside the vehicle, and a blower 2 for discharging inside air installed in the trunk room. It is connected to the blower 3 via air hoses 4 and 5. In the middle of these eight air hoses 4 and 5, there are valves 6 to 6 for intermittent ventilation.
13 is intervening. The blower 2 for introducing outside air is connected to an outlet 14 for introducing outside air into the vehicle interior, and the blower 3 for discharging inside air is connected to an outlet 15 for discharging inside air to the outside of the vehicle.

Figures 2 and 3 are a plan view and a side view of the ventilation duct 1, in which the main body is formed by shaping a mild steel plate with a thickness of 0.8n+m into a flat trapezoid with a rectangular bottom. An air inlet/outlet 1a is provided on each slope. A stainless steel wire mesh 16 for dustproofing is applied to the air inlet/outlet 1a, and the wire mesh 16 and an aluminum cover plate 11, which serves both as fixation and decoration, are attached to the outside of the main body by screws 18 or other methods. Ru. Furthermore, pipe-shaped joints 19 and 20 are attached to two opposing ends of the ventilation duct 1, respectively, for connecting one end of the air hose 4 for introducing outside air and the air hose 5 for discharging inside air.

The ventilation duct 1 is fixed to the ceiling of the vehicle body 5 using a permanent magnet 21 placed on the periphery of the bottom surface thereof.

FIG. 4 shows a plurality of ceiling-mounted ventilation ducts 1, an outside air introduction blower 2 and an inside air exhaust blower 3 that are in charge of supplying and exhausting air to these ducts 1, which are the constituent elements of the device of the present invention, and both of them. Air hose groups 4 and 5 for connecting the blower 2.3 to each ventilation duct 1, and air hose groups 4 and 5 for controlling the switching between outside air introduction and inside air discharge of each duct 1 interposed between these air hose groups 4.5. Valve group, 6-1
Illustrated 3 connection systems.

One of the four Otsuki-mounted ventilation ducts 1 is installed in a place close to each passenger, for example, in a lower part of the upper surface of the armrest A, as shown in the perspective view of FIG. Valve group 10 for selectively operating on the internal air exhaust side
A manual operation panel B for the ventilation duct 1 is assembled, which is a combination of four ON-OFF switches 22 for opening/closing the ventilation duct 13 and a volume 23 for increasing/decreasing the ventilation speed. 2
Reference numeral 4 indicates ports 1 to 4 for attaching armrest 8 to the door panel.

Suppose now that a passenger seated under the lower right duct 1 shown in Fig. 4 starts smoking, one of the four switches on the manual operation panel B should be switched to the one corresponding to the duct from which the smoke should be evacuated. 2
When 2 is pressed, only the valve 13 of the hose connected to the lower right duct 1 of the air hose group 5 for discharging internal air is opened, and the other valves 10 to 12 are in the closed position. On the other hand, among the air hose group 4 for introducing outside air, only the valve 9 of the hose connected to the lower right duct 1 is closed, and the other valves 6 to 8 are in the closed position. Only duct 1 works on the inside air exhaust side, and the remaining three ducts 1 work on the outside air intake side, so that the airflow in the passenger compartment creates a flow that rushes from the non-smoker seat toward the smoker ring when concentrated. As a result, smoke is removed reliably and quickly, and the movement of smoke dispersing into the passenger compartment is completely prevented. Such opening/closing operations of the valve groups 6 to 13 can be determined and automatically performed by an attached electronic control circuit after selecting and operating one of the switches 22 on the manual operation panel B.

Figure 6 shows that the signals from manual operation panel B are judged and valve group 6 is
13 and a wiring system diagram of an electronic control circuit C for issuing instructions to the outside air intake angle blower 2 and the inside air exhaust blower 3. In the figure, 25 and 26 are drive circuits for the outside air introduction blower 2 and the inside air exhaust blower 3, respectively, 27 is a damper provided at the outlet 14 for introducing outside air into the vehicle interior, and 28 is the drive circuit.

29-32 are for opening and closing valves 6-9, and 33-36
is a drive circuit for opening and closing the valves 10 to 13. When an instruction to selectively operate the ventilation duct 1 is sent from any manual operation panel B to the electronic control circuit C, a decision is made in this circuit C to open or close the valve groups 6 to 13, and the specified duct 1 is set to work on the inside air exhaust side, and the remaining duct 1 works on the outside air intake side. In addition, regarding the ventilation speed instructions sent from the four manual operation IBs by opening the polycomb 23, the largest speed value is selected and the blowers 2 and 3 for outside air intake and inside air exhaust are given this speed. An operating command is issued such that the following is achieved. When the occupant senses that the smoke has finished exhausting, he turns all the switches OFF, and the electronic control circuit C sends a stop command to blowers 2 and 3. Alternatively, a command to close valves 6 to 9 and stop blower 3 is sent. Emitted.

A plurality of smoke sensors 37 can also be used in place of the manual operation panel B. FIG. 7 is a wiring system diagram for such an embodiment, and the difference from the embodiment shown in FIG. 6 is that the electronic control circuit is changed from C to D, and the switch 22 and volume 23 are The difference is that a smoke sensor 37 is used instead of the smoke sensor 37. Suitably, the smoke sensor 31 is located close to each ventilation duct 1. Based on the smoke amount information emitted by each sensor, the electronic control circuit determines which of the ventilation ducts 1 should be used to discharge the inside air, and from then on, the valve group is opened and closed and the blower is operated according to the manual operation method described above. operation is performed automatically. When two or more sensors 37 emit smoke signals, the decision as to which ventilation duct 1 should be used to discharge the inside air is made based on data regarding the amount of smoke generated versus the operating state of the duct, which is stored in advance in the circuit. It is done in comparison.

According to this method, if cigarette smoke is generated in the passenger compartment, smoke evacuation will begin automatically regardless of the occupant's will and actions, and the smoke evacuation operation will automatically stop and the vehicle will be covered. All occupants can be protected from the harmful effects of cigarette smoke as mentioned at the beginning, and are also freed from the discomfort caused by choking on purple smoke. In addition, when automatic smoke evacuation is performed using the smoke sensor + J, the smoke evacuation timing and smoke evacuation time can be determined in the most rational manner, so there is the inconvenience that energy for air conditioning is wasted when the air conditioner is forced to work. can be kept to a minimum.

Regarding the wastage of cooling and heating energy due to the smoke evacuation system working while the air conditioner is operating, smoke is removed quickly so there is no need to worry about it, but if necessary, it is necessary to It is also possible to incorporate the smoke adsorption device into the circulation circuit and install the smoke adsorption device in the middle of this circuit.
