Description

A kind of lunch box capable of heating

Technical field

This utility model relates to a kind of lunch box, particularly a kind of lunch box capable of heating.

Background technology

Modern fast pace is lived, many white-collar job persons, field worker, driver, day student etc., usually can not eat at home.Having a lot of lunch box capable of heating in the market, food in lunch box can be heated by a plug-in, and the solution for these personnel's lunch problems provides a great convenience.Existing lunch box capable of heating, there is an outter box, metal heater plate that an inner box and is placed between outter box and inner box, this metal heater plate is resisted against on inner box diapire, during use, heating after this metal heater plate connection external power source, heat is conducted to inner box, thus the food in inner box is heated.But this structure exists some problems, the metal heater plate that during use, inner box is hot with high temperature directly contacts, and plastics local is excessively boiling hot, it is possible to discharges the harmful substances such as plasticizer, infiltrates through in food, affects the health of user；Conventional heating source includes: quartz ampoule, ptc heater etc., and these heating arrangements cannot well be fitted in bottom lunch box, heats uneven, and volume is big, inconvenient to carry, and exists and can produce the shortcoming such as electromagnetic wave, poor stability.This utility model adopts advanced high-temperature alloy material, and lunch box capable of heating structure is improved, it is achieved heat conduction efficiency is high, firing rate is fast, homogeneous heating, easy to carry.

Utility model content

The purpose of this utility model is in that to provide that a kind of heat conduction efficiency is high, firing rate is fast, homogeneous heating, lunch box capable of heating easy to carry.This lunch box includes an outter box, an inner box and a lid, inner box is nested in inside outter box, lid is covered on outter box upper end, and the opening periphery of wherein said outter box and the periphery wall of inner box are tightly connected, and makes formation one airtight accommodation space between outter box and inner box；There is bottom described inner box a groove upwards caved in, inner box is divided into the region of multiple accommodation food；Being additionally provided with a hot plate in the airtight accommodation space of inside and outside box body, described hot plate is attached at inner box diapire, and this hot plate has one upwardly, and this projection can be nested in the groove of inner box；This hot plate has the first insulating barrier, the second insulating barrier and is coated on the heating plate between the first insulating barrier and the second insulating barrier.

Further, described first insulating barrier and the second insulating barrier are polyimide layer.

Further, described heating plate is flexible electrothermal membrane.

Further, described heating plate material is high temperature ferrous alloy.

Further, described heater plate thickness is 0.05～0.5mm.

This lunch box capable of heating of this utility model, compared with background technology, has the advantage that

1. lunch box capable of heating of the present utility model have employed double-layer box design, and food is fully heated by inner box physical ability, and outter box can adopt plastic or other material, effectively completely cuts off the heat of inner box, non-scald on hand and insulation during use；And outter box sealing shroud is connected to outside inner box, form an airtight accommodation space between the two, hot plate and wire etc. can be hidden, avoid user and directly contact the potential safety hazard brought with live wire, when simultaneously can also effectively prevent from cleaning lunch box, current drench hot plate and wire leaks electricity, and make lunch box capable of heating more attractive, safer.It addition, this accommodation space also can play certain heat insulation effect.

2. being provided with a groove upwards caved in bottom inner box of the present utility model, inner box is divided into the region of multiple accommodation food, meal and dish are divided into two independent lattice, practicality is higher.The projection of hot plate can be nested in the groove of inner box simultaneously so that the heating surface area of inner box is bigger, and heats is better, does not have the situation that part superheat section is supercool.

3. lunch box capable of heating of the present utility model adopts high temperature iron-based alloy material to be heating plate material, flexible electrothermal membrane designs in conjunction with upper and lower two layers of polyimide insulating barrier, high temperature iron-based alloy material is flexible, it is possible to be well fitted in bottom lunch box capable of heating so that be heated evenly, firing rate fast；Polyimides has significantly high insulating properties, not easily leaks electricity, good heat conductivity, and heat transfer is fast, and resistance to 400 DEG C of high temperature above, will not melt because hot plate heating, makes hot plate longer service life, safer；Meanwhile, polyimides has good flexibility so that hot plate can be attached at difformity or even nonplanar inner box diapire, and the scope of application is wider.

4. hot plate of the present utility model adopts Electric radiant Heating Film, and thickness is little, lightweight, can effectively reduce lunch box longitudinally height so that it is profile is more attractive compact；And can reduce lunch box overall weight, promote feel when using, more convenient carry.
