Abstract
The utility model relates to a heat preservation lunch box heated by electrically heated water. The heat preservation lunch box comprises a lunch box and a box cover, wherein the lunch box comprises a plastic outer layer, a foamed plastic intermediate layer and a double-layered hollow stainless steel inner layer, and the box cover comprises a box cover insulation layer; a water filling hole is formed in the double-layered hollow stainless steel inner layer, and water can be filled into a hollow cavity of the double-layered hollow stainless steel inner layer through the water filling hole; heaters are respectively embedded among the plastic outer layer, the foamed plastic intermediate layer and the double-layered hollow stainless steel inner layer of the lunch box, a heating rod is arranged on each heater, one ends of the heating rods are connected onto the heater, and the other ends of the heating rods extend into the hollow cavity of the double-layered hollow stainless steel inner layer; and the heaters can be connected with 220V mains sockets through wires to be electrified, and a power-off protection device is arranged on each heater. The heat preservation lunch box can heat by self and has a heat source, the outer, the intermediate and the inner layers of the lunch box are composite heat preservation layers, so that the lunch box has strong heat preservation performance and can be used for heat preservation under both cold and hot conditions.
Description
Technical field
The utility model relates to container, and especially the lunch box technical field specifically, is a kind of incubation canteen of electricity consumption hot water heating.
Background technology
Lunch box is a kind of apparatus commonly used during we live, and title " boxed cassette " is also arranged.People at school, usually will use lunch box in going to work, go on business, travelling.At present, the kind of lunch box is very many, and the type that is not incubated and is incubated is generally speaking arranged.And present incubation canteen mainly be in plastic interlayer filling foamed plastics to form heat-insulation layer.But this is a kind of Insulation of passively object in the lunch box being taked, owing to lunch box itself does not generate heat, without heat energy source, so can't effectively be incubated the object in the lunch box constantly for a long time.In arctic weather the time of its insulation shorter, do not reach the requirement of people expectation.
The utility model content
The purpose of this utility model is to solve the above problems, and provides a kind of lunch box itself can generate heat and have the incubation canteen of the electricity consumption hot water heating of heat energy source, and it is simple in structure and very convenient to carry.
For achieving the above object, the technical scheme taked of the utility model is as follows.
A kind of incubation canteen of electricity consumption hot water heating, contain lunch box, lid, described lunch box contains plastic outer layer and foamed plastics middle level, described lid contains the lid heat-insulation layer, it is characterized in that, described lunch box is provided with double layer hollow stainless steel internal layer in inboard, foamed plastics middle level, and described double layer hollow stainless steel internal layer is provided with water filling port, can carry out water filling in the cavity of double layer hollow stainless steel internal layer by water filling port; Between plastic outer layer, foamed plastics middle level and the double layer hollow stainless steel internal layer of lunch box, be embedded a heater, described heater is provided with heating rod, described heating rod one end is connected on the heater, and the other end extends in the cavity of double layer hollow stainless steel internal layer; Described heater can be connected power taking with the 220V commercial power socket by connecting line.
Further, be provided with the indicator lamp of energising work at described heater.
Further, be provided with power-off protection apparatus at described heater, surpass the design temperature scope in case heater is crossed to scald, power-off protection apparatus can automatic cut-off power.
The good effect of the incubation canteen of a kind of electricity consumption hot water heating of the utility model is:
(1) lunch box itself can generate heat and heat energy source is arranged;
(2) plastic outer layer of lunch box, foamed plastics middle level and double layer hollow stainless steel internal layer form compound heat-insulation layer;
(3) insulating power is strong and can cold-hot heat preservation dual-purpose;
(4) it is simple in structure, easy to carry, and manufacturing process is also uncomplicated.
Description of drawings
Accompanying drawing 1 is the structural representation of the incubation canteen of a kind of electricity consumption hot water heating of the utility model.
Label among the figure is respectively:
1, lunch box; 2, lid; 3, plastic outer layer; 4, foamed plastics middle level; 5, double layer hollow stainless steel internal layer; 6, water filling; 7, heater; 8, heating rod; 9, connecting line; 10, lid heat-insulation layer; 11, water filling port.
The specific embodiment
Provide the specific embodiment of the incubation canteen of a kind of electricity consumption hot water heating of the utility model below in conjunction with accompanying drawing, still, enforcement of the present utility model is not limited to following embodiment.
Referring to accompanying drawing 1.A kind of incubation canteen of electricity consumption hot water heating contains lunch box 1, lid 2, and described lunch box 1 is made of plastic outer layer 3, foamed plastics middle level 4 and double layer hollow stainless steel internal layer 5.Lid heat-insulation layer 10 is contained in described lid 2 inboards.Above-mentioned parts can adopt existing technology and material to make.
Described double layer hollow stainless steel internal layer 5 can be done thicklyer a little, and a trumpet-shaped water filling port 11 and lid are set in the top, can carry out water filling 6 in the cavity of double layer hollow stainless steel internal layer 5 by water filling port 11, then covers tightly with lid.Between plastic outer layer 3, foamed plastics middle level 4 and the double layer hollow stainless steel internal layer 5 of lunch box 1, a heater 7 is set.Described heater 7 can flush with plastic outer layer 3, inwardly extends half of double layer hollow stainless steel internal layer 5.At described heater 7 heating rod 8 is set, the quantity of heating rod 8 and power can be set according to the size (volume that can hold water filling 6) of the cavity of double layer hollow stainless steel internal layer 5.Heating rod 8 one ends are connected on the heater 7, and the other end extends in the cavity of double layer hollow stainless steel internal layer 5.Described heater 7 can be connected and power taking with the 220V commercial power socket by external connecting line 9.
For guaranteeing safety; except the indicator lamp that an energising job is set at described heater 7; should power-off protection apparatus be set at described heater 7, surpass the temperature range of setting in case heater 7 scalds excessively, power-off protection apparatus can carry out self-protection by automatic cut-off power.
The incubation canteen of a kind of electricity consumption hot water heating of the utility model in use, can in double layer hollow stainless steel internal layer 5, be full of water filling 6 first, then heater 7 is connect electrical heating, after double layer hollow stainless steel internal layer 5 reaches heating-up temperature, the food of needs insulation is put into lunch box 1 inner cap upper box cover 2.After having served as several hours, heater 7 can be connect once again electrical heating (heater 7 electrically heated processes can be carried out repeatedly), thereby make lunch box 1 itself keep certain temperature, and then the food in the lunch box 1 is obtained preferably heat insulation effect.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
