Abstract

The utility model discloses a multifunctional electronic lunch box made by utilizing the electric heating element of PTC semi-conductive ceramic, which is composed of components such as a plurality of metal box bodies, an outer box body, a heat insulating layer, a box cover, a frame, sealing strips, etc. Electrical power can be reduced automatically when a temperature inside the lunch box is increased to about 120 DEG. The lunch box is caused to keep a constant temperature state, which avoids rice from burning. The lunch box can utilize commercial power or vehicle electric power to heat rice or steam and boil meals and bake automatically. The multifunctional electronic lunch box has the advantages of naked fire needless performance, safety, convenient operation, and outstanding energy saving, which can be daily used for extensive workers, students, the old, and children. The multifunctional electronic lunch box can be made into a heating lunch box for the special use of motor-vehicle drivers to eat hot meals at any time if the low-voltage heating element of the PTC semi-conductive ceramic is adopted. Because a peculiar sealing design is adopted, the multifunctional electronic lunch box which can carry liquid food without leakage is used for chilled food to preserve freshness without odor changing.

Description

Multifunctional electronic mess tin

The utility model is personal electric heater.

People's lunch break that is on duty is felt headache because of hot meal problem often, have to utilize electric food warmer or electric cup to take hot meal sometimes, and effect is all undesirable, is not that buying expenses height, power consumption are exactly greatly that to be easy to a meal burnt, also need someone look after.Especially driver and field work personnel can have good to eat hot rice and dish and are difficult for especially.The purpose of this utility model is: 1. the electric heater power consumption that overcomes common electric cup and so on greatly, not constant temperature, the dangerous disadvantage of naked light is arranged.2. overcome ordinary lunch-box function singleness, the buckle closure Lou disadvantage of soup of sternly not leaking.3. provide the hot meal utensil that uses low pressure (automobile voltage 12V-24V) for driver and field man.At people's different operating condition, the utility model provides the multifunctional thermostatic electronics cutlery box of two kinds of models, a kind of suitable civil power 220V voltage to people.A kind of dc low-voltage 12V-24V voltage that is applicable to.

Be specifically described below in conjunction with accompanying drawing, accompanying drawing is the profile of a specific embodiments.

The utility model mainly is made of metal case (1), outter box (2), lid (3), elastic sealing strip (4), framework (5), insulation material (6) and heating (7).Described heating is a PTC semiconductive ceramic electric heating element.Place between two metallic objects.So-called PTC semiconductive ceramic electric heating element is that Main Ingredients and Appearance is the ceramic electric heating element of barium titanate.This kind heating is when reaching the temperature of particular range, and its resistance value can sharply increase, thereby electric thermal power is sharply descended, and plays the effect of heated at constant temperature.The utility model utilizes this kind electric heating element and custom-designed for this reason structure, makes the interior object heating of box rapidly, but can not be higher than specified temp (as 120 ℃), thereby can not stick with paste meal.

One side of this multifunctional thermostatic electronics cutlery box bottom has a safety power source plug socket that is connected with contact conductor.For improving economize on electricity and heat insulation effect, around the metal case and between the outter box insulation material layer is arranged.

In the embodiment shown in the figures, metal case 1 is all stretched by aluminium sheet and forms.PTC semiconductive ceramic electric heating element is wrapped in the high temperature insulation film, is placed in two metal case Zhong And and is firmly clamped by two metal case.The electrode slice of electric heating element is connected on the safety socket by contact conductor.This embodiment can use the 220V AC power.The starting power of cutlery box was at 100W when temperature was low.And temperature is when rising to 100 ℃ rapidly, and electrical power only is 20W.Change suitable substance P TC heating, can utilize automobile 12V dc source, very suitable to the driver like this.

The utility model possesses also that rice is cooked rice over a slow fire with giving birth to, the function of fricassee stew and oven dry except that having special automatic hot meal, heat insulation function.The dress liquid food can not leak by Vent in sealing characteristics made reliably.Put into refrigerator after the object cooling in the box, guaranteed that food fresh keeping is not scurried flavor in the box because sealing is good.The utility model power savings, safe effect are very remarkable.This cutlery box not only can have fabulous use value for the hot meal of old man, children or the use of cooking at home again for people's working, use when going out, and is the daily-use electrical appliance of a new generation.

Claims

1, a kind of multifunction electronic cutlery box, by a plurality of metal case, outter box heat insulation layer, lid, framework, sealing strip and heating are formed, and it is characterized in that described heating PTC semiconductive ceramic electric heating element between metal case, and are clamped by the side of two metallic objects.

2,, it is characterized in that inserting in the frame slot with the flange of the can of flange according to the described electrical heating cutlery box of claim 1.

3,, it is characterized in that an elastic sealing strip is arranged between box body and the lid according to claim 1 or 2 described electrical heating cutlery boxs.

4, according to claim 1 and 3 described electrical heating cutlery boxs, it is characterized in that between metal case exposed parts and the outter box insulation material layer being arranged.
