Description

  The present invention relates to a vending machine that uses a solar cell to supply electric power.

  In general, vending machines store products such as beverages, cool or heat them, and provide consumers with appropriate temperature products.

  In recent years, due to the problem of power shortage, vending machines perform cooling or heating during times other than the time when power usage is concentrated, such as daytime, and stop cooling systems or heating systems with high power consumption during times when power usage is concentrated In order to reduce power consumption, many operations are set to save power.

  In recent years, vending machines have consumed a great deal of power to illuminate the display in order to improve brightness and cleanness in order to improve the product image.

  In addition, vending machines themselves are becoming larger and more selective year by year, and the power used by vending machines increases.

  On the other hand, energy saving is screamed due to environmental problems and the like, and an energy saving vending machine that uses less power is required.

  In order to satisfy the above-described requirements, the vending machine is equipped with a solar battery that converts light into electric power and a storage battery that charges the electric power generated by the solar battery, and is automatically sold by the electric power charged in the storage battery. There is a vending machine that saves energy by providing a part of electric power used in the lighting device of the machine (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 4-312198

  However, in the above-mentioned conventional vending machine, the power generated in the solar battery is charged in the storage battery during the time when the sunlight hits, so that it is used in the lighting device at night. It does not use electricity and is often not necessary in the daytime, but even if it is used, the power generated by the solar cell depends on the weather at that time. , Had a problem that it can not be used.

  In addition, since the solar cell that can be mounted on the vending machine is small, it cannot obtain a large amount of power and cannot be used for a cooling system, a heating system, or a carry-out system with high power consumption. It was.

  This invention solves the said conventional subject, and it aims at providing the vending machine which can be utilized for stabilization of the inside temperature, without wasting the electric power which generate | occur | produced in the solar cell. .
