Abstract
The utility model discloses a solar thermal-insulation heating lunch box which comprises a box cover and a box body, wherein the box cover is provided with a solar cell panel; the bottom of the cover body is provided with a charging layer which consists of a charging control circuit and a storage cell; a thermal baffle is arranged above the charging layer and is provided with a heating cavity; a heating circuit is arranged in the heating cavity; and the storage cell is a power supply of the heating circuit. The lunch box is capable of heating food directly by utilizing solar energy, and is energy-saving, economical and practical, free of environment pollution, small in occupied space, and easy to carry.
Description
Technical field
The utility model relates to a kind of Heat preservation equipment, specifically a kind of warming solar energy lunch box capable of heating.
Background technology
Along with the raising of people's living standard, people go out toward away to play and go back to nature, but the inconvenience of having dinner of travelling outdoors, and go to the restaurant to have dinner and are subject to the restriction of time and distance.When people are thirsting for having appreciated the Nature beautiful scenery, also can conveniently have food good to eat, health.Therefore people look forward to producing and integrate lunch box convenient, environmental protection, the most structure of incubation canteen of selling in the market is simpler, can't accomplish long insulation, the function that does not also have heating, people are after lunch box splendid attire food, after a while food will naturally cool off and affect edible, be unfavorable for the person health.Be carried into open-air long-time after, lunch box will lose the effect of heating warm-keeping, thereby brings very large inconvenience to people.
The utility model content
The purpose of this utility model is, a kind of safe and reliable, energy-conserving and environment-protective is provided, is easy to carry, and is not subjected to any environmental limitations, can continue insulation, the warming solar energy lunch box capable of heating that can simply heat again simultaneously.
The technical scheme that adopts to achieve these goals is: the warming solar energy lunch box capable of heating, comprise lid and box body, be provided with solar panel on the described lid, described box body bottom is the charged layer that charging control circuit and battery consist of, the charged layer top is provided with a thermal insulation board, thermal insulation board is provided with a heating chamber, heating chamber inside is provided with heater circuit, described battery is the power supply of heater circuit, consisted of temperature-control circuit with heater circuit, lid adopts flip-shell to be connected with box body, makes things convenient for solar panel to pass through the junction output lead and is connected with battery with the charging control circuit of box body bottom.Described temperature-control circuit is provided with two kinds of patterns, and low temperature insulation pattern and high-temperature heating pattern are provided with heat-insulation switch and heater switch in the box body outside.
The utility model directly utilizes solar energy to heat to food, saves the energy, and is economical and practical, non-environmental-pollution, and it is little to take up room, and is easy to carry about with one.Select the insulation pattern when carrying food, food is in keeping warm mode always, and is edible at any time.For some solid food of carrying, vacuum bag food can be selected heating mode, carries out Simple heating, makes people also can be able to eat hottish food in the open air, has greatly improved the health index of human body simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of warming solar energy lunch box capable of heating described in the utility model; Accompanying drawing 2 is schematic diagram of the present utility model.Among the figure: 1, lid, 2, box body, 3, solar panel, 4, heating chamber, 5, charged layer, 6, heat-insulation switch, 7, heater switch.
The specific embodiment
Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments: the warming solar energy lunch box capable of heating, comprise lid 1 and box body 2, be provided with solar panel 3 on the described lid 1, described box body bottom is the charged layer 5 that charging control circuit and battery consist of, the charged layer top is provided with a thermal insulation board, thermal insulation board is provided with a heating chamber 6, heating chamber inside is provided with heater circuit, described battery is the power supply of heater circuit, consisted of temperature-control circuit with heater circuit, lid 1 adopts flip-shell to be connected with box body 2, and solar panel 3 is connected with battery with the charging control circuit of box body 2 bottoms by the junction output lead.Described temperature-control circuit is provided with two kinds of patterns, and low temperature insulation pattern and high-temperature heating pattern are provided with heat-insulation switch 6 and heater switch 7 in the box body outside.The operation principle of described warming solar energy lunch box capable of heating is: solar panel 3 is converted to electric energy with solar energy and is stored in the battery by charging control circuit, battery is the heater circuit power supply as power supply, during use, open heat-insulation switch 6 or heater switch 7, heater circuit enters low temperature insulation pattern or high-temperature heating pattern, is the meal insulation heating.Described warming solar energy lunch box have quick heating, thermal efficiency height, the flames of anger, smoke dust, without pernicious gas, to surrounding environment do not produce heat radiation, volume is small and exquisite, security good and the advantage such as appearance looks elegant, can finish the heating tasks of having dinner in the field.And to environment without any pollution.Because of the machinery-free machinery, so noiselessness, friction, long without wearing and tearing, life-span.
