Abstract
The utility model relates to an electric heat preservation box which is used for heating foods and preserving the heat of foods. The utility model is provided with a box barrel clamped with heat insulation materials, wherein, a box cover is arranged on the box barrel, and the bottom of the box barrel is provided with an electric heating element. The electric heating element is connected with a socket of a power supply. The electric heating element adopts a PTC element sold in markets and can heat after the electric heating element is energized, and electricity is automatically cut off when definite temperature is reached. When temperature in the box is lower than the definite temperature, the utility model is automatically energized, and thus, foods in the box are kept in definite temperature for preserving the foods.
Description
The utility model relates to a kind of Electric heating box that is used for food heating and heat-insulating.
The existing utensil that is used for food heat-insulation as vacuum flask, generally adopts the double glazing glass liner, and the vacuum flask of plastic sandwich is also arranged, and can only the food that heat be incubated, and temperature retention time is limited.
The purpose of this utility model is that a kind of Electric heating box that can heat and can keep constant temperature to food will be provided.
The utility model is achieved in that a box bucket that accompanies insulation material, on lid is arranged, heating, heating joining power socket are arranged at box bucket bottom.
The PTC element that sell heating employing market, the heating of energising back is cut off the power supply when reaching uniform temperature automatically, is lower than this temperature value and can connects power supply automatically again, causes and maintains uniform temperature preservation food in the box for a long time.
Structure below in conjunction with the description of drawings Electric heating box.
Accompanying drawing is the structural representation of Electric heating box.
With reference to accompanying drawing, columniform box bucket 1 is made up of bucket 6 in shell 4 and the metal, is filled with insulation material 5 between shell and the interior bucket, and insulation material adopts foamed plastic.Place a PTC heating 7 in metal under the bucket, the PTC element is existing on the market approved product, and it has electric heating and automatically controlled two kinds of effects.By storing 500g to 1000g food, keep 70 ℃ of temperature and consider, select the PTC element of 6W to 10W for use.PTC element two connector lugs are connected in the supply socket 9, and indicator lamp 8 in parallel has lid 2 on the box bucket on socket, and lid and box bucket all have two lugs to insert in the slotted hole at plastic handles 3 two ends.
