Abstract

PROBLEM TO BE SOLVED: To deal with power failure or variation of reception of electricity by utilizing a hybrid automobile using an engine with an electric motor, and taking out electric power at parking as a cogeneration system. SOLUTION: An engine 2 is a gasoline engine, and when it is used as cogeneration during parking, it is changed so as to be operated by town gas. Further, the engine 2 is used at the point of relative high output of always good efficiency, surplus output for driving the vehicle is transferred to a generator so as to store power in a storage battery, and on the contray when power is insufficient for driving the vehicle by only the engine, an electric motor is driven by the storage battery so as to help the power of the engine 2. During operation of the engine 2, exhaust heat is thermally changed for water heat through an exhaust heat exchanger 4 so as to make hot water, and the hot water is stored in an on-vehicle hot water tank 5. The hot water is transferred to a hot water tank 6 for dwelling house after homecoming of the vehicle for utilizing it. When this cogeneration system is utilized during parking, electricity is taken our through a connecting terminal 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simpler use of a Kogene system which has been adopted for energy saving.

[0002]

2. Description of the Prior Art The prior art Kogene was a cumbersome and expensive system with different responses. For this reason, there were difficulties in spreading it to ordinary households.

[0003]

In order to obtain a standardized and inexpensive Kozene system, it is necessary to use mass-produced inexpensive components. As for fuel, it is desirable to use city gas used in ordinary houses. In addition, the electric energy generated by the generator and the hot water energy generated as cylinder cooling hot water and exhaust gas heat exchanger hot water generated as engine waste heat are accumulated, and the load of electric energy and hot water energy that is likely to occur in houses is reduced. It is necessary to install storage batteries and hot water tanks to cope with fluctuations. Without these, Kozene's merits cannot be demonstrated.

[0004]

[Means for Solving the Problems] The development of the world's first hybrid vehicle for mass production using both an engine and an electric motor for the advancement of energy saving has been announced and has been receiving a great response. This means that the engine, generator and storage battery of the components that make up the Kozene system will be mass-produced together, and if a hot water tank and an exhaust heat exchanger for the engine are added to this,
Kozene parts will be completed. In this hybrid vehicle, of course, a diesel is also possible, but first, it is a gasoline engine, and it is easy to switch to city gas fuel while parking. In addition, it is possible to easily convert the low-voltage DC electricity of the storage battery into AC electricity for home use by using inverter technology, which has been in demand in a solar cell system. In addition to the small-sized hot water tank loaded on the car, a large-sized hot water tank is provided for stationary installation of the house to facilitate the operation.

[0005]

An embodiment will be described with reference to the drawings. FIG. 1 is a plan view showing the overall configuration of the present invention. Reference numeral 1 denotes an automobile body, which is an ordinary passenger car of about 1500 CC. Reference numeral 2 denotes an engine, which is a gasoline engine, and is switched to operate with city gas when the vehicle is parked and used as a generator. The engine is always used at an efficient and relatively high output place, and the excess output for driving the car is transferred to a generator and stored in a storage battery.
On the other hand, when the engine alone does not have enough power to drive a car, a storage battery is used to turn the motor to assist the engine. Reference numeral 3 denotes a city gas connection terminal, which is configured so that the gasoline circuit is cut off by the connection and the city gas circuit is opened. In some cases, it is conceivable to charge city gas into a high-pressure cylinder and run with city gas. Reference numeral 4 denotes an exhaust heat exchanger that exchanges heat with the exhaust of the engine to recover waste heat as hot water. Reference numeral 5 denotes an in-vehicle hot water tank that stores hot water for cooling the engine and hot water for the exhaust, and uses the hot water tank for home use after returning home. Reference numeral 6 denotes a hot water tank for a house, which copes with fluctuations in demand for hot water and functions so that Kozene operates without loss. Reference numeral 7 denotes a hot water connection terminal, which is connected during parking, transfers hot water stored in the vehicle hot water tank 5 during running to the house hot water tank 6, and effectively utilizes waste heat during running of the vehicle. Reference numeral 8 denotes an electric connection terminal, which is an electric connection path when used as a cogene system during parking. As a result, the generator and the storage battery of the vehicle are effectively used in the system of the house, and it is possible to cope with fluctuations in the demand for electricity. Since the city gas connection terminal 3, the hot water connection terminal 7, and the electric connection terminal 8 are detachable at the same time, if the terminals are integrated so that they can be connected with one touch, it becomes even easier. Electricity is DC, but as in the case of solar cells, it is converted to household AC using a semiconductor converter. When this is introduced, the high temperature part of cooking becomes electric heat, the low temperature part becomes hot water, and naturally heating and bath become hot water. City gas is completely used as engine fuel and waste heat is recovered. In short, the efficiency of gas stoves is eliminated.Essentially, the present invention makes effective use of cars that are often idle in parking lots of houses, and even a small step toward solving the tense carbon dioxide problem and energy saving. It is something that will go on.

[0006]

According to the present invention, the efficiency of energy consumption is rationalized, and the efficiency is about 30% when electricity is produced and transmitted at a remote power plant, but is reduced to about 80% in the Kozene total energy system as in the present invention. This leads to significant energy savings and environmental benefits due to reduced carbon dioxide emissions. The reason that such kosene has not spread until now is that the system is expensive, and by using mass-produced and inexpensive automobiles as in the present invention, this difficulty is overcome.
