3 is an exploded perspective view of a room mirror having a built-in microwave generator according to an embodiment of the present invention, and FIG. 4 is a view in which the room mirror of FIG. 3 is combined.

3 and 4 , the rearview mirror 200 is attached to or coupled to the upper side of the windshield 17 so as to be rotatable in at least two degrees of freedom through a pivot device.

The rearview mirror 200 is fixed to the upper inner surface of the windshield 17 using the support 250 in advance of the room.

The rearview mirror 200 is formed in a form in which a mirror unit 210 is coupled to a housing 220 forming an exterior, and the mirror unit 210 is coupled to the housing 220 by a mirror fixing unit 230 .

A microwave generator 240 for generating microwaves is installed inside the housing 220 .

The microwave generator 240 includes a magnetron 241 for generating microwaves, an antenna 242 for inducing microwaves generated from the magnetron 241, and a microwave induced through the antenna 242 in the windshield 17 direction. It includes a guide portion 243 for radiating.

The magnetron 241 is a high-frequency oscillation tube that generates microwaves of about 2.45 GHz.

The guide part 243 forms an outlet 243a so that microwaves generated from the magnetron 241 and induced through the antenna 242 are radiated, and the microwaves radiated through the outlet 243a are directed toward the windshield 17 . designed to occur.

As described above, the microwave generator 240 is a device for heating an object to be heated by generating microwaves, and is a device for heating an object to be heated by using a dielectric heating phenomenon caused by microwaves, which are high-frequency electromagnetic waves. Specifically, when an object to be heated is exposed to an electric field, polarization occurs while molecules having a dipole moment such as water molecules inside the object are oriented in the direction of the electric field. If the object to be heated is exposed to an alternating electric field such as microwaves, the dipole orientation is repeated in a short time and the dipole vibrates or rotates while generating heat to heat the object. The microwave generator 240 may heat the object to be heated by using the dielectric heating phenomenon by microwaves. As described above, a mechanism for generating thermal energy of microwaves for heating the object to be heated will be described with reference to FIG. 5 .

5 is a view for explaining a mechanism for generating thermal energy of microwaves applied to the present invention.

In FIG. 5 , when a molecule constituting a liquid or a solid has a dipole, the microwave induced rotation of the molecule while passing between the anode and the cathode. At this time, as the rotating molecules collide with other molecules, high-frequency vibrations occur, and thermal energy is generated through this phenomenon. A representative example of a molecule that effectively exhibits this phenomenon is water. The microwave can effectively remove the snow or ice accumulated on the windshield 17 by using the principle of generating heat easily by inducing vibration of water molecules. In addition, when snow freezes at extremely low temperatures, since the bonding force between molecules is strong, an additional liquid component such as a washer liquid may be used to shorten the ice making time.

Since the microwave requires a small amount of power, the 12V voltage of the basic battery applied to the vehicle 1 can be used. Microwaves target near-field and require only enough energy to turn snow and ice into liquid. Therefore, according to an appropriate design goal, it is possible to manufacture as small as possible to be installed inside the rearview mirror 200 . In addition, since there is no harmfulness to the human body, it is suitable for application to the vehicle 1 .

That is, the microwaves generated by the microwave generator 240 radiate the discharge port 243a in the direction of the front windshield of the vehicle 1 , so that the driver (including passengers) riding inside the vehicle 1 is not affected.

Meanwhile, in one embodiment of the present invention, the microwave generator 240 is installed in the interior of the rearview mirror 200 as an example, but the present invention is not limited thereto. 1) It goes without saying that the same object and effect as the present invention can be achieved by installing it at any position radiating in the direction of the windshield 17 in the front.

Hereinafter, an operation process and effects of a windshield snow removal apparatus, a vehicle including the same, and a method for controlling a snow removal apparatus according to an embodiment of the present invention will be described.

8 is an operation flowchart illustrating an algorithm for generating microwaves through a user operation in the snow removal apparatus of the windshield according to an embodiment of the present invention.

In FIG. 8 , the user checks the degree of freezing of snow or ice accumulated on the windshield 17 , and inputs a first, second, or third stage operation signal through the input unit 310 ( 400 ). The manipulation signal input through the input unit 310 is transmitted to the control unit 330 .

Accordingly, the control unit 330 determines whether the manipulation signal input through the input unit 310 is the first stage ( 402 ).

As a result of the determination in step 402, if it is the first stage, the controller 330 applies a voltage to the magnetron 241 installed inside the rearview mirror 200 for a first time every predetermined time ( 404 ).

When a voltage is applied to the magnetron 241 , the magnetron 241 generates a microwave of about 2.45 GHz for the first time ( 406 ), and the microwave generated for the first time in the magnetron 241 is transmitted through the antenna 242 . induced

The microwave induced through the antenna 242 is guided through the guide unit 243 and radiated to the outside through the outlet 243a. Since the discharge port 243a is designed in the windshield 17 direction, the emitted microwave is radiated in the windshield 17 direction as shown in FIG. 6 ( 408 ).

As the microwaves are radiated in the direction of the windshield 17 , thermal energy is transferred to the windshield 17 for the first time, so that snow or ice accumulated on the windshield 17 can be effectively removed.

Then, the control unit 330 counts the total operating time (Tm) of the microwave generator 240 for generating microwaves by applying a voltage to the magnetron 241 to remove the snow or ice accumulated on the windshield for a reference time (Ts). It is determined whether the required snow-making and ice-making time, about 10 minutes) has elapsed ( 410 ).

As a result of the determination in step 410, if the reference time Ts does not elapse, the operation is fed back to step 402 to apply a voltage to the magnetron 241 for a first time every predetermined time until the reference time elapses to continue the operation of generating microwaves. proceed with

Meanwhile, if it is determined in step 402 that it is not the first stage, the control unit 330 determines whether the operation signal input through the input unit 310 is the second stage ( 412 ).

As a result of the determination in step 412 , if there is a second stage, the controller 330 applies a voltage to the magnetron 241 installed inside the rearview mirror 200 for a second time every predetermined time ( 414 ).

When a voltage is applied to the magnetron 241 , the magnetron 241 generates a microwave of about 2.45 GHz for a second time, and the microwave generated for the second time at the magnetron 241 is induced through the antenna 242 .

The microwave induced through the antenna 242 is radiated through the outlet 243a formed in the guide part 243 .

As the microwaves are radiated toward the windshield 17 , thermal energy is transferred to the windshield 17 for a second time. At this time, since the thermal energy transferred to the windshield 17 when the microwaves are generated for the second time is greater than the thermal energy transferred to the windshield 17 when the microwaves are generated for the first time, the windshield 17 ), the accumulated snow or ice can be removed more quickly.

On the other hand, if it is determined in step 412 that the second stage is not the second stage, the control unit 330 determines whether the manipulation signal input through the input unit 310 is the third stage (416).

As a result of the determination in step 416, if it is not step 3, the controller 330 feeds back to step 402 to proceed with the subsequent operation.

Meanwhile, as a result of the determination in step 416 , if there is a third stage, the controller 330 applies a voltage to the magnetron 241 installed inside the rearview mirror 200 for a third time every predetermined time ( 418 ).

When a voltage is applied to the magnetron 241 , the magnetron 241 generates a microwave of about 2.45 GHz for a third time, and the microwave generated for the third time at the magnetron 241 is induced through the antenna 242 .

The microwave induced through the antenna 242 is radiated through the outlet 243a formed in the guide part 243 .

As the microwaves are radiated in the direction of the windshield 17 , thermal energy is transferred to the windshield 17 for a third time period. At this time, since the thermal energy transferred to the windshield 17 when the microwave is generated for the third time is greater than the thermal energy transferred to the windshield 17 when the microwave is generated for the second time, the windshield 17 ), the accumulated snow or ice can be removed the fastest.

On the other hand, when the three-stage operation signal is input through the input unit 310 , the user judges that the degree of freezing of the ice accumulated on the windshield 17 is severe and it is expected that it will take a long time to remove the ice.

Accordingly, the control unit 330 additionally injects the washer liquid when the microwave is generated for the third time period. This is to inject additional liquid along with the generation of microwaves in order to shorten the time required to remove the ice frozen on the windshield 17 when the snow that fell overnight is frozen due to the extreme low temperature.

In this way, the user determines the degree of freezing of the snow or ice accumulated on the windshield 17 and inputs the first, second, or third stage operation signal, and the first time, the second By applying a voltage to the magnetron 241 for 2 or 3 hours to generate microwaves, it is possible to remove snow or ice accumulated on the windshield 17 .

Meanwhile, as a result of the determination in step 410, when the total operating time Tm of the microwave generator 240 has passed the reference time Ts, the control unit 330 determines that the snow or ice accumulated on the windshield 17 has been removed, The voltage applied to the magnetron 241 is cut off ( 420 ).

When the voltage applied to the magnetron 241 is cut off, the generation of microwaves is forcibly stopped and the operation is terminated ( 422 ).

Meanwhile, in one embodiment of the present invention, it has been described as an example that microwaves are generated in one stage, two stages, or three stages in order to remove snow or ice accumulated on the windshield 17, but the present invention is not limited thereto. can be further subdivided or the microwave generation time in each step can be adjusted.

Those of ordinary skill in the art related to the embodiments of the present invention will understand that it may be implemented in a modified form without departing from the essential characteristics of the description. Therefore, the disclosed methods are to be considered in an illustrative and not a restrictive sense. The scope of the present invention is indicated in the claims rather than the detailed description of the invention, and all differences within the equivalent scope should be construed as being included in the scope of the present invention.
