Abstract

The present invention relates to an electric heater for vehicles, which is used for heating containers which contains food or beverage. The present invention comprises a soft outer sleeve which is wrapped around a container, a foldable electric heating element which is installed in the outer sleeve, a conducting wire and an electrical connector. The electric heater is connected with a cigarette lighting socket of a vehicle.

Description

Electric heater for vehicle use

The present invention relates to electric heater for vehicle use, be used to heat the container of splendid attire food and drink.

Take advantage of the driver or the passenger of long-distance car travelling usually to realize, particularly at the night of rural area, want to obtain hot food or beverage to keep their good health, car was hindered, this also is difficult to.For those with special difficult problem especially then for the father and mother of baby or child travelling.Have cooking utensils in some vehicle, but their are mostly heavy and expensive, and always are limited to those luxurious sedan limousines and just are equipped with them.So just be sought after a kind of light, Food ﹠ Drink heater that the individual is special-purpose, and the power supply on the available car makes their work, to save the trouble of carrying balancing cell during the journey.

But, some problem is but hindering the development of this class heater.At first, such heater must be a waterproof, so that whatsoever liquid overflows to be sprinkling upon and all unlikelyly on the heating element causes the vehicle power short circuit.Secondly, when Foods or drinks was heated to the boiling point of water, everywhere heater internal structure all should be fire-retardant near any heating element.The 3rd, such heater should be able to be at lower voltage, and as 12V or 24V work down, adapting with Vehicular power system, and its energy consumption should be less, in order to avoid just exhaust the battery on the car in the not long time.At last, in use, the outside of heater should maintain lower temperature, and unlikely scald user.

The purpose of this invention is to provide a kind of vehicle power, little power consumption, waterproof, automobile-used heater fire-retardant, safe in utilization of being applicable to.

According to the present invention, a kind of electric heater for vehicle use is provided, be used for heating the container of splendid attire Foods or drinks.It comprises a suitable container soft outer layer on every side that is rolled in, and said skin has an internal layer that contacts with heated container, a skin, and a bent electrical heating elements that is bonded on the thermal conductive material layer, it places between described internal layer and the skin.Electric heater also comprises the thermal insulation layer between described thermal conductive material layer and described skin.

The heating element layer is preferably made with two-layer Heat Conduction Material and is adjacent to contact, and an electric plug is provided again, and electrical heating elements is received on the cigar lighter on the car.

Thermal conductive material layer preferably includes an aluminum slice or a plurality of metal material thin slice, has at least one deck to have fabric gasket in the said thin slice, prevents the Heat Conduction Material fault rupture.Said metal material is aluminium preferably.

Be preferably in and put the material layer that one deck keeps heat between said thermal insulation layer and the said Heat Conduction Material.

Electric heater of the present invention can be widely used in whilst on tour and heat various containers, as baby's feeding bottle, and packed hot dog or sealed food.

Describe when of the present invention with a kind of preferred implementation, can see can drawing about a lot of other variations of the present invention and remodeling, and its application.

Below promptly by way of example, the contrast accompanying drawing further describes a kind of embodiment of the present invention, wherein:

Fig. 1, be the perspective view of electric heater, the inner surface of expression overcoat, the promptly said surface that contacts with container;

Fig. 2, be another perspective view of electric heater, the outer surface of expression overcoat;

Fig. 3, be the perspective view that electric heater is used to heat baby bottles;

Fig. 4, be the decomposition view of electrical heating elements.

The contrast accompanying drawing, electric heater comprises the bent electrical heating elements 2 (only shown in Figure 4) of 1, one tape insulation layer of fabric overcoat of a softness, lead 3 and power supply connector 4 are received cigarette lighter socket on the car with electrical heating elements 2; On overcoat 1 inner surface on adhesive sheet 5a, 5b and overcoat outer surface from adhesive sheet 6a, 6b, they are closely linked overcoat 1, be enclosed within outside adhesive sheet 7,8 makes and be closed into flat shape no the time, suspension ring 9 can make electric heater and the container that heated is hung on the hook in car.

With reference to Fig. 4, overcoat 1 comprises a heating element 2, and it is preferably made with resistive material, and the outside has insulating coating, and forms many U-shaped bends above it.Heating element 2 is done outside between the shim liner 1d and interior shim liner 1e, and each pad all has the pad of a thin aluminium flake and a polyester fine rule, makes heating element 2 and aluminium surface contact with each other in fact.Heating element 2 is bonded on the aluminium surface of a shim liner, in order to avoid heating element dislocation or entanglement after using several times.Using aluminum slice, is because of its softness, can tolerate high temperature that heating element 2 produces and unlikely being burnt, more because of its good thermal conductivity, so very fast evenly the scattering of heat that can also heating element 2 be produced by interior shim liner 1e.The direct benefit of heat of scattering fast is to avoid the heat because of being produced to concentrate the problem that burn the part that causes along electric heating element 2 length directions.In addition, polyester fine rule pad is used for protecting unlikely being converted into of flake aluminum to split shape fold and rupture.

In addition, also have cotton layer 1c and spongy layer 1b,, prevent that useful heat from overflowing or leak to the outer surface of electric heater of the present invention as heat guard.So the combined effect of cotton layer 1c and spongy layer 1b is to guarantee that the heat of being given birth to flows to heated object, and remaining outer surface is under enough low temperature, can be safely and be used for comfily by it.This cotton layer 1c also has a subsidiary advantage as flame-retardant layer, because pure cotton is fire-retardant.In addition, the most handy waterproof material of surperficial 1a of the surperficial 1f of the inside and outside is made as nylon, so that any liquid excessive spreads all unlikely short circuit that causes heating element, and this is possible cause damaging power-supply system on the car.

Claims
