Description of the Related Art Heating the cabin of an automobile is usually performed by circulating engine cooling water through a heat exchanger for indoor heating, and discharging the heat generated from the engine into the cabin through the heat exchanger. However, in order to protect the engine, the engine cooling water is controlled by a thermostat so that it does not circulate until it reaches a certain temperature. Even if the heat exchanger for indoor heating is activated, heating is not obtained and cold air is discharged. For this reason, immediately after the start of operation during the cold season when heating is required, the interior of the cabin remains cold and is forced to remain unheated.
このことから、エンジンを始動させて自動車を運転する

あり、普及するまでには至っていない。For this reason, in order to heat the cabin immediately after starting the engine and driving the car, an electric heater is installed in the heat exchanger installed in the cabin, separate from the engine cooling water circulation path. A method has been developed that allows the electric heater to operate only for a short period of time immediately after the start of operation. However, this method
In order to obtain sufficient heating, electric power exceeding the capacity of the generator attached to the engine must be passed to the electric heater, which causes the battery to wear down significantly, causing the problem of having to recharge the battery frequently. However, it has not become widespread due to the problems that it causes.

担が大きい問題がでてくる。In addition, in order to heat the cabin, which is cold immediately after the start of operation, without using an electric heater that consumes the battery, it is necessary to reduce the amount of heat emitted from the engine during the previous operation. The heat is stored by a heat storage means, and this amount of heat is released during the next operation and used for heating immediately after the start of operation.When the engine warms up, the circulation of cooling water begins and it is used for normal room heating. When a heat exchanger starts to operate as specified, a part of the heat released from the heat exchanger is stored, and this stored heat is released again when the next operation starts. However, in this way, the amount of heat stored during the previous drive can be used even if the car is left in the cold until the next drive. It is a prerequisite that the heat storage means is configured to maintain a state in which heat is stored without being released. However, it is difficult to construct a heat storage means that does not radiate heat even when exposed to cold air.
With the usual means of storing heat in paraffin or the like as a heat storage material (thermal medium), there is a problem that heat is inevitably released over time, and a large amount of heat medium is required for heat storage, so a tank with a considerable capacity is required. This creates a problem of heavy weight and capacity burden.

する新たな手段を提供することを目的とする。The present invention was made in order to solve these problems that occur in heating means for the interior of a car, and it uses a part of the heat generated by the engine during normal driving without being supplied with heat. The stored heat is stored in a heat storage means that can be maintained in a state where it will not be released even if left unattended, and the heat is stored in a cold state the next time the engine is started and operation begins. By making it possible to release heat for heating a certain cabin, when the engine is just started and the cabin is cold at the start of operation, the heating in the cold cabin is caused by the release of the heat stored during the previous operation, which causes the battery to drain. To provide a new means that can be effectively carried out without causing wear and tear and without imposing a burden on the capacity and size of an automobile body.

好な結果が得られたことに基づくものである。Therefore, the present invention has been completed based on the knowledge obtained through various studies for the above-mentioned purpose. In other words, when the amount of heat generated by the engine during operation is stored in a heat storage material and the stored amount of heat is released for indoor heating at the start of the next operation, the amount of heat generated from the heat storage material is If the amount of heat is released only by decreasing the temperature of the heated heat storage material (heat medium), it will be possible to reduce the amount of heat released from the heat storage material while the car is left unused after driving. A heat retention method is required to suppress the heat loss, and it is impossible to expect the heat retention method to be perfect.
If the time until the next operation is long, the amount of heat stored in the heat storage material will be released before it can effectively heat the inside of the cold cabin. However, after driving a car, it is left standing until it is driven again, so it is supercooled by using sodium thiosulfate, sodium acetate, etc., which is left to cool slowly while standing still. The heat storage material is made of a material that instantly causes a phase transformation from a liquid phase to a solid phase by applying a shock or vibration to it, and at that time releases heat equivalent to the heat of fusion. This heat storage material is turned into a liquid phase by the amount of heat generated by the engine during normal driving, and then it is stored in a supercooled state by being left in a natural state while the vehicle is left standing until the next operation. However, I came up with the idea of applying a shock to this the next time it is operated to cause a phase transformation, generating an amount of heat equivalent to the heat of fusion, and using this as a heating source at the start of operation. This is based on the fact that good results were obtained with this configuration.

暖房装置を提起するものである。Therefore, in the present invention, as a means to achieve the above-mentioned object, by cooling sodium thiosulfate or sodium acetate in a stationary state, it becomes supercooled while remaining in the liquid phase, causing shock or shock. A substance that transforms into a solid phase by breaking its supercooled state when subjected to vibration is used as a heat storage material, and the heat storage material is kept in a liquid phase by the heat generated from the engine during driving, making it possible to control the operation of a car. By leaving the heat storage material in the cold air until the next operation, the heat storage material is left to cool and become supercooled, and when the next operation starts, the supercooled state of the heat storage material is changed by shock or vibration. The present invention proposes an instant heating method for automobiles, which is characterized by destroying the vehicle and generating heat equivalent to the heat of fusion, and using that heat to immediately heat the cabin, which is cold at the start of operation. The hot air duct of the indoor heating system is equipped with a liquid such as sodium thiosulfate or sodium acetate, which is cooled in a stationary state and left in a supercooled state by applying vibration or vibration. A heat exchanger for instant heating, which is filled with a heat storage material made of a substance that transforms into a solid phase by destroying the supercooled state, is used instead of a heat exchanger for indoor heating installed in the hot air duct. The present invention proposes an instant heating device for an automobile, which is arranged and assembled on the air outlet side.

かけることなく、効果的に行なえるようになる。As explained above, in the method of the present invention, when sodium thiois or sodium acetate is cooled in a stationary state, the supercooled state remains in the liquid phase, and the supercooled state is broken by applying a shock or vibration. A heat storage material is a substance that undergoes a phase transformation into a solid phase when the vehicle is driven, and the heat storage material is kept in a liquid phase by the heat generated from the engine during driving, and is used in cold air between the time the car is driven and the next time it is driven. By leaving the heat storage material in a stationary state, the heat storage material is allowed to cool down to a supercooled state, and at the next start of operation, the supercooled state of the heat storage material is destroyed by stamping or vibration to generate an amount of heat equivalent to the heat of fusion. The engine generates heat and uses that heat to immediately heat the cabin, which is cold at the start of operation, so some of the heat generated by the engine during normal operation is left without heat supply. The stored heat will not be released even if the system is in use, and it can be stored in the heat storage means as a heat source for immediate heating at the start of operation the next time.
The next time you start the engine and begin operation, the immediate heating of the cabin, which is cold at the start of operation after the engine has just been started, releases the amount of heat stored in the heat storage material during the previous operation. Therefore, this can be done effectively without causing battery consumption and without imposing a burden on the capacity and size of the vehicle body.
