With conventional hot water heaters installed in vehicles, it took a long time to produce hot air. Furthermore, when a nichrome wire type hot air heater or the like is used, the air must be heated once and the window glass must be warmed from the inside using that air, which results in poor heat transfer efficiency and requires a large amount of electric power.

に着氷は取り除ける。In Figure 1 (a+), the infrared rays emitted from the heating element 1 are absorbed to some extent by the windshield 6, but most are absorbed by the icing 7 (4).The infrared rays are received through the windshield 6. Therefore, the melting part 7a of the ice accretion is generated from the connection part between the window glass 6 and the ice accretion 7. At this time, the infrared rays absorbed by the window glass 6 also turn into heat, which leads to heat conduction and melts. Heat is supplied to the portion 7a.As mentioned above, since a melting portion is generated between the window glass 6 and the icing 7, icing can be easily removed by operating the windshield wiper, for example. It can be removed.

てゆく。In this device, the following operations are performed so that the above-mentioned functions can be performed efficiently. As an example in Figure 2,
A circuit diagram for operating the device is shown. This device is stored in the dash board 5 when not in use. Then, when using the device, open the lid 5a on the dashboard. Then, when the switch SWI is turned on, the relays CR1, CR2, and CR3 are activated, and the motor 4 with reduction gear and the heating element 1 are energized. Then, the heating element slowly begins to rotate in an arc around the shirt 4a, and at the same time, the heating element 1 generates heat and begins to emit infrared rays (5). Then, the heating element 1 moves slowly while emitting infrared rays, and during this time, the infrared rays melt the ice.Then, when it rotates to a preset angle, the limiter switch 8a is turned on, and the relay CR4 and CR5 are activated, relay R4 turns off relays CR1, CR2, and CR3, and the power to the motor 4 with a reduction gear and the heating element 1 is cut off. At the same time, the motor 4 with a reduction gear is energized in the opposite direction, and deceleration occurs. The geared motor 4 rotates in the opposite direction, and the heating element 1 also returns in the opposite direction.If the wiper is operated during this time, the ice can be easily removed.Then, the geared motor 4 turns off the limiter switch 8b. As a result, the power supply to the motor 4 with a reduction gear is finished, and the motor stops when it returns to its original position.
During this return, the heating element is cooled by the surrounding air.

い。(6) By the way, as mentioned above, in order to rotate the heating element,
In this device, the heating element efficiently emits infrared rays.
In addition, in order to reduce the weight of the heating element and to increase the heating rate of the heating element, a heating element having a structure as shown in FIG. 1 (fl) is used. The ceramic substrate 13 is made thinner than the ceramic substrate 11 to increase the temperature increase rate on the ceramic substrate 13 side, and the black coating 1 is also applied.
4 makes it easier to emit infrared rays. The reason is that, as shown in Figure 3, the black coating 1 of the heating element
This is because most of the infrared rays are emitted from the 4th side. Furthermore, as shown in FIG. 1(a), the contact area of the fixing part 3 between the heating element 1 and the cover 2 is reduced, that is, the heating element 1 is suspended in the air, so there is less heat conduction, and the cover 2
Since the inner surface of the cover reflects infrared rays, the cover itself receives almost no heat from infrared rays, and furthermore, this reflected infrared rays are absorbed by the heating element itself and the windshield.
The light is irradiated onto the glass, making it extremely energy efficient. Furthermore, since the heating element is made of ceramic (7), it is extremely lightweight compared to a sheath heater or nichrome wire with the same heating area. (The amount of radiation is proportional to the area of heat generation.) Furthermore, the cover of the rotating part can be made lighter by using heat-resistant resin or aluminum, and the load on the motor is also small.

め、本装置専用の駆動用モータを無くすことができる。Next, FIG. 4 is a schematic diagram showing the configuration of a second embodiment of the device of the present invention. In this embodiment, the operating shaft of the wiper is shared, and the heating element is rotated via an electromagnetic clutch and a universal joint. It is something. When the switch of this device is connected to the wiper operation switch and the switch is turned on, the wiper
is activated, and at the same time, the electromagnetic clutch 52 and the heating element 1 are also energized, and while the heating element 1 generates heat, the wiper operating shaft 51,
The cover 2 and the wiper 50 operate together to remove ice through an electromagnetic clutch 52, a universal joint 53, and a bearing 54. When the switch is turned off, the wiper switch is also turned off, the wiper 50 stops at its original position, and the heating element and the like automatically stop at their stopped positions. In this embodiment, since the wiper motor is used as the power source (8), it is possible to eliminate a dedicated drive motor for this device.

In this case, the storage location of this device is shared with the defosogare outlet for the vehicle air conditioning, and the device is configured so that it does not operate unless the vehicle air conditioning mode is in the defosogate position, and the device is stopped and stored. Afterwards, it is safer if the heater fan motor 55 rotates for a while and the heating element 1 is cooled by the wind.

静粛性に富んだ除氷装置が得られる。Next, FIG. 5 is a schematic diagram showing the configuration of a third embodiment of the device of the present invention. In this embodiment, the heating element 1 is fixed as it is in the housing part 5, and the infrared rays from the heating element 1 are Part 5
The side walls of the housing part 5 and the inside part of the lid 5a are coated with a metal coating and mirror-finished to have a high reflectance so that infrared rays are not absorbed inside and become high temperature, and so that the window glass 6 is effectively irradiated with infrared rays. . By doing this,
Although the deicing efficiency and speed are inferior to the first and second embodiments, since there are no moving parts, a deicing device with a very simple structure and quietness can be obtained.

This is a partial cross-sectional schematic diagram showing the structure of another example of the heating element in the example, and in FIG. It is possible to further increase the heating rate on the crystallized glass surface side where a large amount of infrared rays are emitted.In addition, parallel resistor patterns may also be used. However, in this example, several parts are arranged in parallel, so even if one part is insulated, other parts generate heat, so it can be used without any problem to some extent. Although the distance becomes longer, by increasing the distance between the resistor 12 and the mounting hole 18, the temperature of the mounting portion becomes lower, so it can be advantageous in terms of heat resistance.

を取り除くことができるという効果が大である。As described above, the automobile deicing device according to the present invention includes a heating element that emits infrared rays, a cover having a reflective surface that reflects infrared rays, and a heating element holder that fixes the heating element to the cover, and includes a heating element that emits infrared rays. The infrared rays are designed to irradiate the ice, frost, etc. adhering to the glass through the windshield, so that the infrared rays melt the ice through the windshield, and the melting portion is applied to the contact area between the windshield and the ice. Therefore, by operating the wiper before all the ice has melted, the ice can be removed easily, quickly, and efficiently, which is very effective.

大である。Further, in the heating element of the device of the present invention, a resistor is printed on the upper surface of a first ceramic substrate, and the resistor is covered with a second ceramic substrate thinner than the first ceramic substrate. The top surface of the ceramic base is treated to increase the emissivity, for example, with a black coating made of crystallized glass, and the inside of the cover 2 is coated with metal such as chrome plating. This has a significant effect in that the radiation efficiency of the long line is particularly improved.
