Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mounted solar-powered idling control system and an air-conditioning operating unit capable of operating an air-conditioning adjusting device when a vehicle engine is stopped.

[0002]

[Prior art]

 Automotive air conditioners adjust the temperature, humidity, airflow and ventilation using ventilators, heaters, and coolers. The conventional water-cooled engine is a hot water hitter system, and the hot water heated by starting the engine is sent to the heater core as a heat source. When ventilation air passes over it, it is warmed and blown into the car. In the cooler function for cooling and dehumidification, the compressor uses a condenser to perform heat exchange by vaporization and liquefaction of the refrigerant. In this compressor as well, the rotation of the engine is transmitted from the crankshaft by a magnet tarratch and the like, compressing the refrigerant and starting the cooling function. Thus, in the conventional heater system and cooler system, the engine cannot be started until the engine is started. For this reason, when parking or stopping, if heating or cooling is required, it must be used in an idling state. In winter and cold regions, it is necessary to warm the engine by idling after starting the engine by the starter and before running. Furthermore, in summer, the idling speed must be higher than usual, taking into account the load on the engine of the compressor due to cooling. Even when the temperature inside the car, which has been left outdoors due to a rise in the outside air temperature, rises sharply, the ventilation system cannot be used without starting the engine. Since most drives of conventional air conditioners can be used after the engine is started, there are many problems when used in an idling state.

[0003]

[Problems to be solved by the invention]

 This invention replaces idling when the engine starts and stops when the vehicle is parked and stopped.It has a heating system that heats the engine and enables heating, a cooler system that enables cooling and a ventilator for ventilation. The purpose is to allow the system to function with the driving force of a solar cell that is mounted later on a part of the vehicle body.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, this invention is based on a solar battery attached to a part of the vehicle body and an air conditioner including a heater device, a cooler device, a blower device, and a power supply including a time switch. It is a unit with a switching mechanism.

[0005]

[Action]

 The unit of the invention allows the engine to be warmed by the electric energy of the solar cell before starting the engine of the vehicle. In addition, the air conditioner can be started before the engine is started by the time switch, and the room temperature inside the vehicle can be set to a constant temperature before the boarding by the thermostat. Therefore, even when the air conditioner is parked or stopped, the engine can be stopped and the air conditioner can be operated without idling to adjust the temperature inside the vehicle. In addition, it may be unnecessary to increase the idling speed, which is the burden on the compressor due to cooling, by using two types of batteries together.

FIG. 3 is a three-dimensional view of a vehicle heating system. 31 is a radiator, 32 is a radiator cap, and 33 is a shih tzu heater part of the unit of the present invention, which is inserted into the radiator and sealed instead of the cap. 34 is a thermostat and a radiator fan switch, and 35 is a water valve. FIG. 4 shows the principle of cooling of an automobile, where 41 is a compressor, 442 is a magnetic clutch, and 43 is a crankshaft. Reference numeral 44 denotes a DC motor unit of the cooling operation device of the unit of the present invention. 45 is a condenser, 66 is a receiver and dryer, 67 is an expansion valve, and 68 is an evaporator. The solar cell (25) for the unit of the invention is safely and fully mounted and fixed outside the vehicle body. This solar cell can supply enough current to drive the blower fan at 12V. The amount of current generated by solar irradiation is displayed. If overcurrent flows, the car battery is charged. This solar cell is connected to a relay that works as an air-conditioning operating device through a current converter that makes the current constant. Next, first, the heater device is connected to this relay, a current flows, and the heater device becomes operable. The heater unit of this unit consists of a Shih Tzu heater part (31) and a thermostat. This Shih Tzu heater part is U-shaped and is inserted into the coolant inside the radiator from the lid of the radiator (32). However, a sealing stopper can be used instead of the lid. Therefore, the cooling liquid can be directly heated to a certain temperature. At this time, the temperature of the coolant in the radiator rises with the water valve (35) closed, and when the engine temperature rises to the set temperature, the water valve opens automatically to prevent overheating of the engine, Heated coolant circulates through the heater core) to start heating and heating. When the heater core reaches a certain temperature, the thermostat operates and the blower fan operates. The cooler actuator is then made up of a DC motor (22) and a thermostat, also connected to a relay connected from a solar cell and directly connected to the drive shaft of the compressor. When a current flows through the cooler operating device, this DC motor is driven, and when the compressor (41) starts up, the refrigerant that has been switched on to the condenser fan starts circulating, and when the temperature reaches the set temperature by the thermostat, the blower fan also operates. Then cooling starts. These devices first determine which air conditioning to select based on the electromotive force of the solar cell, set the temperature inside the vehicle, start operation with a time switch, and automatically operate the temperature inside the vehicle by the action of a thermostat. Can also be set. In addition, the function (23) of the electric switching mechanism allows the current to be switched smoothly from the solar battery to the car battery at the same time as the engine is started. When cooling is used, it is not necessary to increase the idling speed by using the current from both. The air-conditioning device automatically starts heating when the engine and cooling water are sufficiently heated by the heater device by the function of the thermostat, and even when the engine is stopped, the air conditioning for heating, cooling, ventilation, etc. Enable operation of the actuator. Although the embodiment has been described above, the present invention can be applied to the next embodiment.If the electromotive force of the solar cell can supply a sufficient current to drive this unit, the existing device can be used. Attached to water-cooled engine vehicles. The heater and cooler of this unit can be selected according to the season and region. Any type of DC battery that has a sufficient electromotive force to drive the unit of the present invention can be used regardless of its type. If the output of the solar cell is different due to different sunshine hours and the output of the solar cell is not constant, it can be replaced with an alternative rechargeable solar cell.
