Description

A kind of multifunctional lunch box
Technical field
The utility model relates to daily necessities field, relates to particularly a kind of multifunctional lunch box.
Background technology
That sold in the market is can lunch box capable of heating of a great variety, but function is very dull, can can only rest on heating this part by lunch box capable of heating, the lunch box of this class, is using the hot meal of Hot dishes also passable reluctantly winter, but to summer, this class lunch box also can only be used as common lunch box and use, because the food in summer seldom needs heating, simultaneous temperature is too high also can cause that food is rotten at short notice, can not reach fresh-keeping effect, also be not suitable for long-distance band and send food.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of double heating, cooling, fresh-keeping in the multifunctional lunch box of one.
Technical scheme: for achieving the above object, multifunctional lunch box of the present utility model comprises lunch box body and cover of the lunch box, described lunch box body is three-decker, comprise be positioned at innermost layer zone of heating, be positioned at the cooling layer in intermediate layer, be positioned at outermost refrigerating layer, wherein, in described zone of heating, be provided with heater strip and be filled with and heat electrolyte, in described refrigerating layer, be provided with semiconductor cooler and be filled with refrigeration electrolyte, described cooling layer is used for passing into cooling medium; Described heater strip is connected with power supply by a two-way switch with semiconductor cooler, and described two-way switch is arranged at the outer wall of lunch box.
Wherein, described cooling layer is provided with water inlet on the top of lunch box sidewall, in the bottom of lunch box sidewall, is provided with delivery port, and described water inlet and delivery port all communicate with described cooling layer.
Described cooling medium is water or frozen water.
In use, during food in needing lunch box capable of heating, by two-way switch, heater strip is communicated with power supply, semiconductor cooler disconnects, and heating wire heats and passes to and heats electrolyte, thereby heats; When need to be to food fresh-keeping in lunch box, the inlet opening that can arrange by lunch box sidewall passes into cold water or frozen water, thereby carries out fresh-keeping; In the time need to refrigerating the food in lunch box, by two-way switch, semiconductor cooler is communicated with power supply, heating wire disconnects, and semiconductor cooler starts refrigeration, and makes refrigeration electrolyte cooling around, reaches the object of refrigeration.
Beneficial effect: compared with prior art, multifunctional lunch box of the present utility model can reach heating, cooling (refrigeration) and fresh-keeping effect simultaneously, convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of multifunctional lunch box, comprise lunch box body 1 and cover of the lunch box 2, lunch box body is three-decker, comprise be positioned at innermost layer zone of heating 3, be positioned at the cooling layer 4 in intermediate layer, be positioned at outermost refrigerating layer 5, wherein, in zone of heating 3, be provided with heater strip 6 and be filled with and heat electrolyte, in refrigerating layer 5, be provided with semiconductor cooler 7 and be filled with refrigeration electrolyte, cooling layer 4 is for passing into cooling medium, as water or frozen water; Heater strip 6 is connected with power supply by a two-way switch 8 with semiconductor cooler 7, and two-way switch is arranged at the outer wall of lunch box, by two-way switch, can optionally make power supply be connected with heater strip 6 or semiconductor cooler 7.Described two-way switch connects external power source (not shown) simultaneously.Cooling layer 4 is provided with water inlet on the top of lunch box sidewall, in the bottom of lunch box sidewall, is provided with delivery port, and described water inlet and delivery port all communicate with described cooling layer.
In use, during food in needing lunch box capable of heating, by two-way switch, heater strip is communicated with power supply, semiconductor cooler disconnects, and heating wire heats and passes to and heats electrolyte, thereby heats; When need to be to food fresh-keeping in lunch box, the inlet opening that can arrange by lunch box sidewall passes into cold water or frozen water, thereby carries out fresh-keeping; In the time need to refrigerating the food in lunch box, by two-way switch, semiconductor cooler is communicated with power supply, heating wire disconnects, and semiconductor cooler starts refrigeration, and makes refrigeration electrolyte cooling around, reaches the object of refrigeration.
