Description

[Detailed Description of the Invention] The present invention provides a method for ventilating the interior of a vehicle when getting into the vehicle, and in particular, a method for ventilating the interior of a vehicle when the vehicle is parked in the scorching sun, and in particular, when the vehicle is parked in the hot sun and the vehicle is about to get on the vehicle again, the key can be inserted into the key hole of the door for a short time. The present invention relates to a ventilation method in which air is discharged from the vehicle interior, and a ventilation method in which the vehicle interior is further cooled by operating the vehicle air conditioner for a short period of time.

If a car is parked for a long time on a street under the scorching sun on a clear day or in a season of strong sunlight, the interior of the car will become quite hot, and it is extremely uncomfortable to get in and expose yourself to it. To solve this problem, open the window and
Furthermore, the air inside the vehicle may be forcibly discharged by driving the interior air exhaust blower. Furthermore, when an air conditioner is provided, the window is closed again and the air conditioner is operated. However, in order to take these measures, it is necessary to get into the car at least once, and it is inevitable that at least the driver and the like will be exposed to the high-temperature air inside the car. Further, if the air conditioner is often operated without completely releasing high-temperature air, the cooling load is large, which is not preferable in terms of power saving.

Therefore, the object of the present invention was devised in view of the above-mentioned points, and by simply inserting the key into the door, if the temperature inside the vehicle is heated to a high temperature of 35 degrees Celsius or higher due to parking, , provides a method for ventilating the interior of a vehicle when riding in a vehicle, in which a blower for discharging interior air or a fan motor of a vehicle air conditioner is automatically driven for a short period of time, and windows are automatically opened to increase the exhaust efficiency of the blower, etc. In addition, just by inserting the key into the door, the window not only opens automatically and drives the blower or fan motor to rapidly exhaust hot air from the passenger compartment, but also automatically closes the window again and restarts the engine. Embodiments of the present invention will be described in detail below.

First, an embodiment of the indoor ventilation method for riding in a vehicle according to the first invention of the present application will be described with reference to FIGS. 1 and 2. In Figures 1 and 2, 1
2 is a key switch, 2 is a determination drive circuit, 3 is a vehicle interior temperature sensor, and 4 is a blower provided on the parcel tray side at the rear of the vehicle or a fan motor of a vehicle air conditioner (not shown). Now, when the key is inserted into the door, the determination drive circuit 2 and the cabin temperature sensor 3 are activated by a signal from the key switch 1. When the vehicle interior temperature is, for example, 35° C. or higher, the determination drive circuit 2 outputs a drive command to the blower or fan motor 4, and the blower 4 and the like are driven for, for example, one minute. In order to continue driving the blower etc. even when the key is pulled out, the key switch 1 may be provided with a self-holding circuit controlled by a time constant circuit, for example.
To have the judgment drive circuit 2 output a signal to drive the blower 4 when the cabin temperature exceeds 35°C,
A set value signal corresponding to 35°C is stored in the same circuit 2, and this set value signal is compared with the input signal from the cabin temperature sensor 3, and when the latter is equal to or larger than the former, the blower 4 is activated. The configuration may be such that it can output a relay signal for this purpose.

You can open the windows to effectively exhaust the high-temperature cabin air using the blower 4, etc., but if the windows are not designed to open automatically by a drive device, you have no choice but to open the door. You can open the window by turning the steering wheel without entering the vehicle. In particular, if the window is structured to open automatically by a drive device, or even if it is not, in order to automatically open the window simply by inserting a key into the door, an existing or new window opening/closing drive (not shown) is required. What is necessary is to have the device output an open drive command via the determination drive circuit 2.

According to the indoor ventilation method when riding in a vehicle configured as described above, when the vehicle is parked in the hot sun for a long time and the vehicle is to be driven again, the key switch 1 is turned on simply by inserting the key into the door. As a result, the judgment drive circuit 2 and the cabin temperature sensor 3 are also turned on, and if the cabin temperature exceeds 35°C, the judgment drive circuit 2 operates to drive the blower 4, etc., and the windows are automatically opened. In this case, the blower 4, etc. is operated for one minute, for example, to forcibly exhaust the high-temperature air inside the car, lowering the temperature inside the car to almost the same as the outside temperature in a short period of time, making the person trying to drive feel uncomfortable. This improves the cool-down performance when you get in the car, start the engine, and drive the air conditioner.

Next, an embodiment of the indoor ventilation method for riding in a vehicle according to the second invention of the present application will be described with reference to FIG.

In Fig. 3, 1 is a key switch, 2 is a judgment drive circuit, 3 is a vehicle interior temperature sensor, 4 is a fan motor for a blower or vehicle air conditioner, 5 is a self-holding circuit, 6 is a timer, and 7 is a window opening/closing circuit. 8 is a switch that is turned on when the handbrake is engaged, 9 is a switch that is turned on when the transmission is in neutral, 10 is a starter that starts the engine, and 11 is a switch that detects that the engine is rotating. The rpm sensor 12 indicates a compressor of a vehicle air conditioner. FIG. 4 also shows a flowchart of this method. Now, if you insert the key into the keyhole of the door, even if you pull out the key, the key switch 1 will be turned on by the self-holding circuit 5 for the time set by the timer 6, for example, 2 minutes, and the key switch 1 will remain on. If so, both the determination drive circuit 2 and the cabin temperature sensor 3 are turned on. The vehicle interior temperature sensor 3 detects the vehicle interior temperature tr and inputs a signal corresponding thereto to the determination drive circuit 2. When the signal from sensor 3 is greater than the signal set in circuit 2 corresponding to the control temperature, e.g. Only when it is confirmed that this is the case, a drive command is output to the fan motor 4 of the blower or vehicle air conditioner and the drive device 7 that opens and closes the windows. Also, at this time, the circuit 2 outputs a drive command to the starter 10,
This will start the engine. The blower 4 is configured to stop after one minute, for example, by a timer built into the circuit 2. Thereafter, only when the rpm sensor 11 detects that the engine is running, the determination drive circuit 2 outputs a closing command to the drive device 7 that opens and closes the window again, and also outputs a closing command to the drive device 7 that opens and closes the window. and outputs a drive command to the compressor 12. Then, when the vehicle air conditioner is activated and the temperature inside the vehicle has decreased to at least equal to the outside temperature ta, a buzzer (not shown) sounds, and at this point a person may enter the vehicle. The vehicle air conditioner operates for about one minute for the remaining time set by the timer 6, and then stops after lowering the vehicle interior temperature tr to below the outside air temperature ta. In short, just by inserting the key, the window is opened and the blower or fan motor 4 is used to forcibly exhaust the cabin air that has been heated to, for example, 35℃ or more due to parking under the hot sun, and there is no risk of the vehicle starting. This series of operations can be performed fully automatically and in a short period of time, starting the engine, forcibly discharging the cabin air as described above, closing the windows again, and allowing the vehicle air conditioner to cool the cabin. As a result, you will not feel any discomfort, and the power required to start the vehicle air conditioner will be reduced, resulting in energy savings.

As explained above, according to the first invention of the present application, when the key switch is turned on and the determination drive circuit determines that the cabin temperature is above a certain temperature, the blower or the fan motor of the vehicle air conditioner is shortened. It has a time-driven structure that forcibly exhausts the air inside the vehicle, so when you park the vehicle in the hot sun and want to drive it again, all you have to do is insert the key and wait a short time without entering the vehicle. Forcibly exhausts the heated cabin air. Therefore, the user does not have to experience the discomfort caused by hot air, and furthermore, if the air conditioner is activated after getting in the vehicle, there is no hot air in the passenger compartment, which improves the cool-down performance of the air conditioner. Further, according to an embodiment in which the window is automatically opened by the determination drive circuit, the above-mentioned forced exhaust becomes more effective.

Further, according to the second invention of the present application, the determination drive circuit that is turned on by the key switch starts the engine if the cabin temperature is above a certain temperature and there is no risk of the vehicle starting. Then, the windows are fully opened and the blower or fan motor is driven to forcefully exhaust the air inside the cabin, and then the windows are fully closed and the compressor of the vehicle air conditioner is driven to lower the cabin temperature to below the outside temperature. Therefore, when you park your vehicle in the hot sun and try to drive it again, you just need to insert the key and wait a short time without entering the vehicle. The air conditioner automatically cools the cabin temperature to below the outside air temperature. Therefore, the cool-down of the vehicle air conditioner is improved, and the vehicle does not experience discomfort when riding.
