Abstract
The utility model relates to a charging insulation lunch box, comprising a box casing, a box liner and a casing cover. Heating wires are arranged on the bottom of the box liner, and rechargeable batteries are arranged on both sides of the box liner. Thermal insulation materials are filled in the gap between the box liner and the box casing, and a temperature control relay is arranged in circuits. When the charging insulation lunch box is used, the batteries are charged by the additional preassembled chargers beforehand. The batteries start working and the lunch box is heated slowly after the lunch is put into the lunch box and a heating switch is switched on. The temperature range is controlled by the relay. The utility model with the advantages of simple structure and convenient operation is suitable for the needs of taking lunch when people travel out. People can eat hot meals even in winter by using the charging insulation lunch box.
Description
The utility model belongs to the daily living article field, is a kind of electric incubation canteen.
People go out, and when not having noon the place to have dinner, often need lunch going along with.For example, numerous students in middle and primary schools, especially rural area, mountain area student go to school, and school and family's apart from each other need the band lunch.Worker's working, driver go out, field work personnel field work, also often need the band lunch.And the band meal also can be saved the household economy spending.At present, the lunch box that the band meal is used great majority is plastic products or aluminum products, does not have lagging facility.After the food of heat was put into, promptly not cooling off for a long time turned cold, and especially in winter, made troubles for people's daily life.
Can electrically heated voluntarily incubation canteen after the food that the purpose of this utility model is to design a kind of heat is put into.
The lunch box of the utility model design is made of box shell, box courage, several parts of lid.Wherein box courage bottom is provided with heating wire, and rechargeable battery is equipped with in box courage two outsides respectively, is filled with insulation material as heat-insulation layer between box courage and the box shell.Battery is connected with heating wire, and the charging jack of battery, charging indication luminous tube, heater switch are arranged at a side of box shell.
When preventing that battery from working to heating wire, the intensification of food too high (too high there is no need) can add a temperature control relay in the line, make temperature reach the requirement of setting after, cut off the electricity supply automatically.
The lunch box of the utility model design, box courage wherein can be divided into two lattice or three lattice, so that distinguish dish-filling, dish or meal, dish, soup.In order to prevent that lunch box porpoising delicacies of the season juice or soup from overflowing, and is provided with seal cover respectively on dish lattice and Tang Ge.
In order to make lunch box that better heat insulation effect be arranged, lid also can be designed to bilayer, and the centre is filled with insulation material and makes heat-insulation layer.
The heating wire power of box courage bottom generally gets final product at 8-15 watt, and battery adopts 22 volts charging cell again.The shape of lunch box and common lunch box are similar, and size is more bigger.Can make different specifications and models.
The box shell of lunch box, box courage, lid can adopt common plastic products, also can adopt metallic article, as aluminium, stainless steel etc.
During use, the charger of joining by other at night, got final product battery charge with 220 volts of civil powers in general 6-8 hour in advance.Before going out, meal, dish, the soup of heat is put into the corresponding space of lunch box respectively, cover the seal cover of dish, Tang Geshang, cover lid again.Open heater switch, battery is promptly started working, and lunch box is slowly heated.Because there is heat-insulation layer box courage outside, and has the heating wire heating, can make food keep certain temperature range.If overheated, under the relay effect, cut off the electricity supply automatically.When temperature was lower than uniform temperature in the box, relay was connected automatically, continued heat tracing.General as with 10 watts heating wire, 22 volts battery can be incubated 6-7 individual hour.
The lunch box of the utility model design is simple in structure, easy to make, uses such lunch box, can make food keep certain temperature, is convenient to people and goes out to be with meal to use.Especially in winter, people still can have the reeky food of oneself liking.
Fig. 1 is the structural representation of this lunch box, does not comprise lid, and dotted portion is represented internal structure.
Fig. 2 is the profile of this lunch box length direction.
Wherein, 1 is the box shell, and 2 is the box courage, and 3 is lid, and 4 is battery, and 5 is heating wire, and 6 is the seal cover of dish, soup lattice, and 7 is heat-insulation layer, and 8 are the charging jack, and 9 is heater switch, and 10 are charging indication luminous tube.
Embodiment.As shown in drawings.The length of lunch box is 200x150x90mm, box shell 1, box courage 2, lid 3, all injection mo(u)ldings.Heating wire 5 power adopt 10 watts, mould technology with embedding and are made in box courage bottom.Battery 4 adopts 22 volts charging cells again.Battery 4, heating wire 5, switch 9 and relay carry out circuit and are connected.Battery 4 is connected with charging jack 8, indication luminous tube 10.Box shell 1 and box courage 2 sealed knots are fixed, and promptly get required lunch box.
