Description

Defroster of automobile using exhaust heat

The present invention relates to an apparatus for defrosting a vehicle using exhaust heat, and in particular, by connecting the washer liquid reservoir, washer pump, exhaust pipe, connection joint, safety valve and washer nozzle with the first, second, third and fourth supply hoses, Normally, the washer fluid is sprayed on the windshield at the normal temperature, while in the cold winter, the defroster of the car using the exhaust heat can be effectively removed by spraying the washer fluid whose temperature is increased by the heat of the exhaust pipe. It is about.

In general, windshields, side glass, and rear glass are installed in order to secure visibility in all directions. In late autumn or winter, the glass surface may be damaged due to frost or airborne dust or algae. Frequently, there were cases where soiling was caused by poor visibility.

In the case of removing the frost in such a state, if the glass surface was directly scratched using the frosting spatula, there was a risk of damage to the glass surface, and the method of melting the frost by operating the heater mounted inside the car also took a long time. There was a problem.

The technical problem of the present invention is to inject the washer fluid at normal temperature into the windshield, while in the cold winter, in order to remove frost or frost, the washer fluid is heated by the heat of the exhaust pipe to the windshield to be frost, etc. To provide a defrosting device for cars using exhaust heat that can be easily removed.

The present invention relates to a defrosting apparatus for a vehicle, comprising: a first supply hose having one end communicated with a washer pump mounted to one side of a washer fluid reservoir to be in contact with an exhaust pipe of an engine; A second supply hose communicating with the other end of the first supply hose with a connection joint, the other end communicating with the safety valve, and sending a washer liquid whose temperature is increased; A third supply hose communicating with both ends of the safety valve and the washer fluid reservoir to pass the cooled washer fluid; It is achieved by configuring a fourth supply hose in which one end is communicated with the safety valve and then communicated with the washer nozzle to selectively send the cold / hot washer fluid.

Figure 1 is a schematic diagram showing a defrost device of the present invention.

As shown in FIG. 1, the defrosting apparatus of the inventive vehicle includes first, second, third and fourth supply hoses 21, 22, 23, and 24.

The first supply hose 21 is passed through one end of the washer pump 12 mounted to one side of the washer liquid reservoir 10 so as to contact the exhaust pipe 14 of the engine.

The second supply hose 22 communicates with the other end of the first supply hose 21 to the connection joint 16, and the other end communicates with the safety valve to send the washer liquid having a raised temperature.

Both ends of the third supply hose 24 communicate with the safety valve 18 and the washer fluid reservoir 10 to allow the cooled washer fluid to pass.

The fourth supply hose 24 is in communication with the washer nozzle 20 after one end is in communication with the safety valve 18 to selectively send the cold / hot washer fluid.

The operation of the present invention configured as described above will be described in detail.

In the case of a cold winter, when the frost or frost forms a windshield 26, it is difficult to secure a field of view, and the washer pump stored in the washer fluid reservoir 10 operates the washer pump 12 to exhaust the hot exhaust pipe 14 of the engine. After passing through the washer to raise the temperature of the washer solution is designed to be able to easily remove the frost and the like by spraying the washer nozzle through the washer nozzle (20).

That is, the defrost structure of the present invention communicates with the first supply hose 21 from the washer pump 12 mounted on the washer fluid reservoir 10 and passes through the exhaust pipe 14 of the engine. Then, the connecting joint 16 communicates with one end of the second supply hose 22, and the other end of the second supply hose 22 communicates with the safety valve 18. The safety valve 18 is connected to the washer nozzle 20 by the fourth supply hose 24. In addition, the washer fluid reservoir 10 and the safety valve 18 are communicated with the third supply hose (23).

Then, the washer pump 12 is normally operated and the washer fluid of the washer fluid reservoir 10 is sent to the safety valve 18 as the second supply hose 22, and the safety valve 18 is opened to obtain a relatively low temperature. The washer liquid is sent to the washer nozzle 20 to be sprayed to the windshield 26. At the same time, the wiper device, which is not shown in the figure, is used to wipe off the dirty contaminants of the windshield 26.

In particular, in the case of cold winter, in order to remove frost and frost, the washer pump 12 is operated to send the washer liquid stored in the washer liquid reservoir 10 to the first supply hose 21, and then the temperature is increased by the exhaust pipe 14. The washer fluid is sent to the safety valve 18 along the connection joint 16 and the second supply hose 22. Subsequently, the safety valve 18 is opened and the washer fluid is sent to the washer nozzle 20 to be injected into the windshield 26. At this time, since the washer fluid is relatively high temperature, the frost and frost formed on the windshield 26 can be easily removed.

According to the defrosting apparatus of an automobile using exhaust heat, the washer fluid reservoir, washer pump, exhaust pipe, connection joint, safety valve and washer nozzle are communicated normally with the first, second, third and fourth supply hoses. While the washer liquid of the temperature is sprayed on the windshield, in the case of a cold winter, the washer solution, which is heated by the heat of the exhaust pipe, is sprayed on the windshield to be effectively removed.
