Description

Automotive bonnet heating device {AUTOMOBILE BONNET HEATING APPARATUS}

The present invention relates to a vehicle bonnet heating device, and more particularly, to a vehicle bonnet heating device capable of securing a driver's view by melting snow accumulated on the vehicle bonnet.

As is well known, a bonnet is a panel covering an engine room provided in front of a vehicle, and such a bonnet is rotatably installed on a vehicle body to open and close the engine room.

In addition, when an internal combustion engine is installed in the engine room and the engine is started, the snow accumulated on the bonnet is melted by the heat generated from the internal combustion engine, so the driver's view can be secured naturally.

On the other hand, in the case of an electric automobile using an electric motor supplied with energy from a battery or a hydrogen fueled automobile using hydrogen as fuel, snow accumulated on the bonnet is not generated even when the engine is started. Since this does not melt, there was the hassle of having to clear the snow accumulated on the bonnet every time to secure the driver's view.

As a prior art for protecting the bonnet of a car, Korean Utility Model Registration No. 20-0149092 (registration date March 23, 1999) 'car cover for preventing fallout' and Korean Patent Publication No. 10-2009-0019285 (published date February 25, 2009) 'vehicle hood panel protective cover' and the like are disclosed.

However, the prior art described above has the inconvenience of checking the weather forecast every day and fixing the cover covering the bonnet by hooking it to the car or attaching it with tape before it snows.

The case 310 constitutes the framework of the air conditioner 300, and the case 310 has an intake port 311 for taking in outside air and the air taken in through the intake port 311 to the indoor air vent of the vehicle 100. It includes a guiding duct 312.

Referring to FIG. 2, an intake port 311 is formed on one side of the case 310 to take in the outside air blown by driving the blower 320 into the case 310, and guide it to the duct 312 on the other side. A defrost air vent 313, a face air vent 314, and a floor air vent 315 for exhausting the air into the room are formed.

Here, mode doors 316 are installed in the defrost air vents 313, the face air vents 314, and the floor air vents 315, respectively, to control the air volume of hot and cold air or to regulate opening and closing.

The duct 312 is a hot air passage 312a that guides the air taken in from the intake port 311 to the PTC heater 340 and a cold air passage that bypasses the PTC heater 340 and directly guides it to a plurality of air vents. (312b), and the hot air passage (312a) and the cold air passage (312b) are opened and closed by the temp door (317).

A bonnet air vent 350 is formed on one side of the duct 312, that is, on one side of the duct 312 close to the defrost air vent 313, and the bonnet air vent 350 is heated by the PTC heater 340. It includes a heating supply line 351 for supplying hot air to the heating line 200 and a heating exhaust line 352 for exhausting cold air cooled by heat exchange with the heating of the bonnet 110 toward the PTC heater 340, As shown in FIG. 2, the outlet side of the heating exhaust line 352 is exhausted between the evaporator 330 and the hot air passage 312a.

It is installed to block the flow in the opposite direction.

The evaporator 330 is installed in the inlet 311 of the case 310 to cool the outside air blown into the inlet 311 by driving the blower 320 .

The PTC heater 340 is installed on the heat passage 312a of the duct 312 to heat the outside air cooled by the evaporator 330 and then supply it to a plurality of air vents.

A PTC heater (Positive Temperature Coefficient Heater, 340) heats the intake air by using the current applied from the battery 370 of an electric vehicle or hydrogen vehicle. It has the ability to maintain temperature. That is, when the current is supplied from the battery 370, the PTC heater 340 generates heat and raises the temperature, and the resistance increases at a certain temperature, so the amount of heat generated decreases due to the decrease in the flowing current. It is possible to maintain a constant temperature in the PTC heater 340 itself only by supplying.

The PTC heater 340 may be operated such that the heating amount is controlled according to a Pulse Width Modulation (PWM) signal output from the control unit 360 .

The control unit 360 controls the operation of the PTC heater 340 according to the operation signal output from the switch 380.

For example, the PTC heater 340 can be controlled to operate or stop according to an on/off operation signal of the switch 380 operated by the driver.

The battery 370 supplies electrical energy to the control unit 360, and the battery 370 may be implemented as a main battery or auxiliary battery that supplies energy to an electric vehicle or a hydrogen vehicle.

On the other hand, the air conditioner 300 includes a temperature sensor 391 for detecting an abnormal temperature of the heat supplied to the heating supply line 351, and an indicator lamp 390 for displaying the abnormal temperature detected by the temperature sensor 391 to the driver. ) may be further included.

The temperature sensor 391 outputs an abnormal signal to the control unit 360 when the temperature of the heat supplied to the heating supply line 351 is detected as higher than the set temperature, and the control unit 360 receives the temperature sensor 391. A display signal is output to the indicator lamp 390 to indicate an overheating state according to the input abnormal signal.

Here, the indicator lamp 390 is preferably installed on the dashboard so that the driver can easily check visually at once.

Accordingly, the driver can check the overheating state of the heat supplied to the heating supply line 351 through the indicator lamp 390 and control it through the switch 380 .

Referring to the accompanying drawings, the overall operation according to the embodiment of the present invention configured as described above will be described in detail.

First, when a driver in the driver's seat of the vehicle 100 operates the switch 380 to output an on operation signal, the controller 360 receives electrical energy from the battery 370 according to the operation signal input from the switch. The PTC heater 340 and the blower 320 are operated simultaneously.

Next, the outside air blown from the blower 320 passes through the evaporator 330, is cooled, and moves to the PTC heater 340 through the hot passage 312a.

Subsequently, the outside air moved to the PTC heater 340 is exchanged for hot air by heating and supplied to the heating supply line 351 through the duct 312 .

Subsequently, the hot air supplied to the heating supply line 351 circulates through the heating line 200 arranged on the inner surface of the bonnet 110 to heat the bonnet 110, and the snow accumulated on the bonnet 110 heats the heating line ( 200) is melted by the heat circulating and flows to the floor.

Finally, the cold air circulated through the heating line 200 and cooled by heat exchange is exhausted in the direction of the hot passage 312a through the heating exhaust line 352, and then heated again by the PTC heater 340. will repeat

Therefore, in the present invention, when snow accumulates on the bonnet 110 of a vehicle 100 that does not use an internal combustion engine, such as an electric vehicle or a hydrogen vehicle, the bonnet 110 is heated by a driver's simple operation, thereby heating the bonnet. It has the advantage of being able to conveniently melt and remove snow accumulated in (110).
