Abstract

A combined structure is adopted for a vehicle-mounted food electric heating heat-preserving box, a box body is composed of five layers from outside to inside, the fiver layers are respectively an outer protecting layer, an outer heat-preserving layer, a heat-containing layer, an inner heat-preserving layer and an inner protecting layer. An insulating layer and the heat-containing layer jointly have effects to preserve heat, and heat preserving time is lasting; and active electric heating heat preserving and positive heat preserving of food self-temperature jointly have effects, and heat preserving time is more lasting.

Description

Vehicle-mounted electro heat food insulation box

Technical field

The utility model relates to a kind of long-time food heat-insulation box structure, relates in particular to a kind of vehicle mounted electric heating food insulation box of heat preservation food for a long time.

Background technology

Existing food insulation box adopts thermal insulating material to make merely, the passive food initial temperature that depends on of temperature retention time, and temperature retention time is the longest to be about 10 hours, if the low insulation time of food self-temperature also will shorten.

The utility model content

Technical problem to be solved in the utility model provide a kind of can electro heat and the insulation combined action, prolong temperature retention time, solve short problem of traditional haybox cooking time.The longest temperature retention time of this electro heat food insulation box can reach more than 24 hours, and the heat tracing time can also be longer if pilot process is had ready conditions, and this product is particularly suitable for the automobile long-term travel, vehicle-mounted food heat-insulation.

The technical solution of the utility model is: this vehicle-mounted electro heat food insulation box adopts composite structure, and casing compositions that be of five storeys from outside to inside is respectively external protection coating, external thermal insulation, culvert thermosphere, inner thermal insulating layer and interior protective layer, and the culvert thermosphere is filled with water.Wherein containing thermosphere is made of the high liquid of specific heat capacity, can use the electric heater heating, heated at constant temperature adopts with PTC thermally dependent resistor temperature booster, heating power supply is AC220V, vehicle-mounted heating can be used the heating of DC24V-AC220V inversion adapter, and once heating the temperature inside the box can keep 24 hours 45 ℃ of temperature.

The beneficial effects of the utility model are:

1, adiabatic layer and the combined action of culvert thermosphere insulation, temperature retention time is lasting;

2, electro heat initiatively is incubated and the passive insulation combined action of food self temperature temperature, and temperature retention time is more lasting.

Description of drawings mark: external protection coating 1, external thermal insulation 2, culvert thermosphere 3, inner thermal insulating layer 4, interior protective layer 5.

The specific embodiment

The utility model is a kind of long-time food insulation box, and as Fig. 1, Fig. 2, shown in Figure 3, its keystone configuration comprises that by renovating and casing that hinge flap connects the both sides of casing are respectively outlet and fill the mouth of a river.As shown in Figure 4, the casing composition that is of five storeys from outside to inside, casing comprise external protection coating 1, external thermal insulation 2 from outside to inside successively, contain thermosphere 3, inner thermal insulating layer 4 and interior protective layer 5, contain thermosphere 3 and are filled with water.

Implementation method: the food after at first will heating is put into insulation box container and building, and then attaching plug is inserted on the outlet of food insulation box and connects power supply, casing is contained thermosphere 3 interior liquid be heated to more than 80 ℃, pulls up attaching plug.Because the total heat of storing in, the insulation can higher from the heat source temperature of insulation can inside increases, temperature retention time is prolonged, and be easy to carry.

Claims

1. vehicle-mounted electro heat food insulation box, comprise casing, it is characterized in that: the described casing composition that is of five storeys from outside to inside, casing comprise external protection coating (1), external thermal insulation (2) from outside to inside successively, contain thermosphere (3), inner thermal insulating layer (4) and interior protective layer (5), and culvert thermosphere (3) is filled with water.
