Description

  The present invention relates to an anti-freezing and de-icing device for a windshield incorporated in a front face of a heavy-duty automobile from a general automobile in winter.

  A general automobile includes a body made of a windshield, a side glass, a rear glass, and a steel plate incorporated in a manufacturing process, an engine mounted in the body, a running tire, and the like.

In particular, in the case of automobiles for general households, there are many cases of so-called blue sky parking in which parking is performed in a parking lot without a garage in a small city area. In addition, in the case of heavy machinery automobiles such as construction machines and civil engineering machines, most of them are parked at construction sites because the machines are large.
Automobiles (heavy machinery) that are not parked in such parking lots are exposed to wind and rain all year round regardless of the season.

  In winter, moisture in the air adheres to the body and windshield due to radiation cooling on the ground and freezes. The freezing of the windshield obstructs the field of view at the start of driving the car and is very dangerous. Ensure visibility.

Assuming such a situation, there is the simplest method for attaching the antifreezing cover (mask) to the body or the windshield so as to cover the surface of the windshield the day before. (Patent Document 1)
However, in this method, both sides of the anti-freeze cover are sandwiched between the front door and the body, and a suction cup pre-attached to the main part of the anti-freeze cover is attached to the windshield for freezing Attach magnets attached to both side edges of the prevention cover by attracting them to the front pillar, etc., but if the attachment is insufficient or strong wind blows, the anti-freezing cover will not come off and exhibit its effect was there.

In addition, this anti-freezing cover is vulnerable to the ultraviolet rays of sunlight and is exposed to the outside air below freezing point, so that it deteriorates quickly and cracks and does not function as a cover.
Furthermore, the antifreezing cover itself is frozen on the windshield due to freezing, making it difficult to remove.

  In view of this, it has been proposed that a heating wire or a planar heater is mounted on the windshield surface and the battery mounted in the automobile is used as a power source to generate heat to prevent freezing. However, this proposal has a drawback in that it causes the battery to run out and causes a trouble that the engine cannot be started.

Although the basic idea of attaching a sheet heater to the windshield is the same, the supply voltage from the in-vehicle battery is raised and lowered by a preset command to supply power to the sheet heater, and when the freeze thaws. A technology with an automatic step-down function that reduces the supply voltage was proposed. (Patent Document 2)
In another method, a heating element formed of an LLC pack with a resin sheet in a bag-like shape is attached to the upper part of the instrument panel at a position located directly under the windshield inside the vehicle, and is provided in the automobile when parking. A relatively high-temperature cooling medium is stored in the tank and kept warm, and when the interior temperature drops to the condensation temperature (freezing), the cooling medium is heat-exchanged to generate heat, and the windshield is heated by the radiant heat. Things were proposed. (Patent Document 3)

  However, the techniques disclosed in Patent Documents 1 and 2 have the above-described problems, and have a drawback that an expected effect cannot be obtained. Patent Document 3 requires that a tank for storing the cooling medium is required, energy for keeping the cooling medium at a high temperature is required, and that the apparatus becomes considerably large and can be easily mounted and set by a user. There are many issues such as not.

  In particular, in Patent Document 3, it is necessary to move the cooling medium after the engine is started, and it is necessary to check for leakage of the cooling medium, and there are many problems in practical use. .

  The present invention solves the problems as described above, and prevents or freezes the windshield of an automobile by a simple and versatile configuration.

  The present invention provides a fluid discharge unit that is detachably attached to a body or a windshield of an automobile, discharges fluid toward the outer surface of the windshield, prevents freezing of the outer surface of the fluorocarbon glass, or defrosts. The fluid discharge unit includes a plurality of discharge nozzles that are horizontally aligned and open toward the outer surface of the fluorocarbon glass, and a guide tube that communicates with the discharge nozzle, and supplies fluid to the guide tube. The fluid is discharged from the discharge nozzle.

In the present invention, a rubber magnet is mounted on the lower surface of the fluid discharge unit in a loose-fit state that allows at least vertical movement within a specified space.
In the present invention, the fluid supplied to the guide tube is warm water or warm air and is discharged from the discharge nozzle toward the outer surface of the fluorocarbon glass.

  In the present invention, the discharge nozzle is configured to be rotatable and set to an angle at a desired position on the outer surface of the fluorocarbon glass.

  The present invention discharges hot water from the discharge nozzle, and supplies hot water from an external hot water source to a fluid hose connected to the guide tube.

  In the present invention, warm water is discharged from the discharge nozzle, and a heater is provided in a fluid hose connected to the guide tube, and the heater is heated by an external power source to prevent freezing in the fluid hose.

  The present invention discharges hot water from the discharge nozzle, and is provided with a fluid coupler that is detachably mounted on one side of the fluid discharge unit and connected to the guide tube when mounted, and the fluid coupler is provided in the fluid coupler. Is a built-in electromagnetic valve that cuts off hot water using a preset means.

  The present invention discharges warm air from the discharge nozzle, and is provided with a fluid coupler that is detachably mounted on one side of the fluid discharge unit and connected to the guide tube when mounted, the fluid coupler comprising: The apparatus includes a hot air generating device including an air inlet, a hot air heater, a motor, a hot air guide, and an air outlet, and the air outlet is connected to the guide pipe when mounted.

  The present invention comprises a reservation timer means for setting a discharge start time a predetermined time before the start time of the engine of the automobile, and a control means for instructing whether or not hot water or hot air can be discharged from the discharge nozzle, When the discharge start time is reached by counting by the reservation timer means, the control means discharges hot water or hot air.

  In the present invention, at least one temperature sensor is installed at a suitable position on a part of the outer surface of the fluorocarbon glass, and the temperature detected by the temperature sensor is below freezing point when the discharge start time is reached by counting by the reservation timer means. When the temperature is below the freezing point, the control means discharges hot water or hot air. When the temperature is below the freezing point, the hot water or hot air is not discharged.

  The present invention detects whether or not the temperature detected by the temperature sensor is below freezing, and when the temperature is below freezing, hot water or warm air is discharged by the control means, and when the temperature detected by the temperature sensor falls below freezing Discharge of hot water or hot air is stopped.

  The present invention is provided with a fluid discharge unit that is detachably mounted on the body or windshield of an automobile, and the fluid discharge unit prevents or freezes the windshield in advance. Unlike what is built in when assembling the production line, it is cheap and simple.

  In particular, the body discharge unit that discharges fluid is detachably mounted on the body or windshield of an automobile, so it can be easily installed and removed with little influence on the design and size of the automobile, and is highly versatile. Become.

  This fluid discharge unit is detachable, so it is not necessary to install it in the season when it is unlikely that the outside temperature will drop to the freezing temperature. It is highly probable.

  In the present invention, since a rubber magnet is mounted on the lower surface of the fluid discharge unit in a loosely-fitted state that allows movement up and down and left and right within a specified space, a steel plate that is normally a magnetic body The mounting and dismounting of the fluid discharge unit to and from the body of an automobile composed of the above will not only be easy, but the body will not be damaged by the rubber magnet. In particular, even if the curved surface of the body is slightly different depending on the type of vehicle model, the rubber magnet moves up and down within a specified space, and the fluid discharge unit can be mounted on the body in a stable state.

  Moreover, since the present invention uses hot water or hot air as the fluid supplied to the guide tube and discharges it from the discharge nozzle toward the outer surface of the fluorocarbon glass, if the fluid is hot water, It is possible to increase the speed in the case of defrosting, and control to increase or decrease the amount of hot water by setting a valve or the like provided in a hot water flow path or the like according to the size of the fluorocarbon glass or the like.

  On the other hand, in the case of warm air, the warm air that hits the windshield diffuses along the outer surface of the windshield and spreads over a wide area, increasing the temperature of the outer surface of the windshield without unevenness and preventing freezing. In addition, the ice can be effectively thawed over a wide range during freezing.

  Further, in the present invention, since the discharge nozzle is configured to be rotatable and set to an angle of a desired position on the outer surface of the front glass, the curved surface of the windshield, the inclination angle, and the mounting position of the fluid discharge unit The most effective angle can be adjusted according to the above. For example, when the fluid discharge unit is always mounted on the same vehicle type, it is always possible to prevent freezing and defrost in an optimal state by first determining the mounting position of the fluid discharge unit and the angle of the discharge nozzle. Will be able to do.

  And since this invention discharges the warm water supplied via the fluid hose from an external warm water source from a discharge nozzle, it obtains after starting the engine of a motor vehicle and performing warm-up operation for a predetermined time. Compared to those using heat energy such as a refrigerant, it has an immediate effect and can complete ice melting in a short time.

  Further, according to the present invention, the hot water from the discharge nozzle can be obtained by heating water passing through the fluid hose with a heater provided in the fluid hose, or from a hot water source provided outside via the fluid hose. When hot water is supplied, the temperature is prevented from dropping and freezing when the hot water is stopped in the fluid hose. That is, the heater provided in the fluid hose has an effect of preventing freezing in the fluid hose.

  Further, according to the present invention, since the fluid coupler that is detachably mounted on one side of the fluid discharge unit incorporates an electromagnetic valve that cuts off hot water by a preset means, the electromagnetic valve Thus, even when the fluid discharge unit is attached, the supply of hot water can be stopped when freeze prevention or deicing is not necessary, and the supply of hot water can be started when freeze prevention or deicing is necessary. This stops useless use of warm water and can use warm water only when necessary.

  In the present invention, a fluid coupler comprising a hot air generator is detachably mounted on one side of the fluid discharge unit, and hot air is discharged from the discharge nozzle. Maintenance and inspection are possible, and the fluid coupler is held in a single state with the fluid coupler detached. For example, if there is a thick frozen part on a part of the windshield, it can be defrosted intensively by a hair dryer method. it can.

  Further, the present invention discharges hot water or hot air when the discharge start time is reached by counting by a reservation timer means that sets a discharge start time a predetermined time before the start time of the engine of the automobile. If hot water or hot air is discharged by the reservation timer means, the windshield is not frozen during driving of the automobile, and a good view can be obtained and safe driving can be performed.

  Furthermore, the present invention provides at least one temperature sensor at an appropriate position on the outer surface of the fluorocarbon glass, and discharges hot water or hot air when the temperature detected by the temperature sensor is below the freezing point when the discharge start time is reached. However, if the temperature is below the freezing point, warm water or warm air is not discharged, so that wasteful warm water flows out or wastes electricity even though the outer surface of the fluorocarbon glass has not dropped to the freezing temperature. Use to avoid a situation where hot air is discharged.

  Then, the present invention discharges hot water or hot air when the temperature detected by the temperature sensor is below freezing, and stops discharging hot water or hot air when the temperature is below freezing in the discharge state. Spillage, use of electricity can be avoided.
