Description

Automobile electrothermic food and drink device

The utility model relates to a kind of electrical equipment that is used for heated food on the automobile.

Prior art is about the electrical equipment of heated food on the automobile, the external information (electronics newspaper phase in 89 on September 10, the 36th) that micro-wave oven is installed on automobile is arranged, will there be 1/4th automobile installation micro-wave oven in U.S. Jeannette Campbell company prediction U.S. in 2000, and Japanese a company has applied for the patent of automobile microwave oven supply power.The power consumption of micro-wave oven and is difficult to bear to general automobile power source usually more than 500W, and the key of using vehicle micro-wave oven is to solve the problem of inverter and the energy problem of power supply, because its complex structure cost height then is difficult to popularize.Domestic automobile does not generally have foods heat unit, there is not the beverage heating arrangement yet, electric heating food incubation chamber (patent No. 91215565.5) and multi-functional health protection electric heating mess tin (patent No. 95240188.6) that title " driver is happy " arranged on the existing market, product has DC12V, plurality of specifications such as AC220V, its structure is that the aluminium lunch box of plastic closure is heated by heat generating component roughly the same, the electric heater of plastic casing insulation.Its shortcoming is: (1) moulding is not ideal enough, is difficult to find correct position to put in the operator's compartment, when driving turning over or displacement easily.(2) can only heat food such as food can not heated beverage.(3) the food box long-time heating food of plastic closure, aluminium lunch box structure and food not too meet hygienic requirements.

Because the power supply energy of automobile is limited, the space is little, unfavorable factors such as driving moderately gusty air, and the technical matters that this electric appliances emphasis need solve is to cut down the consumption of energy, and improves heat to imitate the problem of appearance structure idealization.

The purpose of this utility model provide a kind of on automobile the electrical equipment of heated food and beverage, the characteristics that can adapt to automobile power source, particular job environment that meets chaufeur, make this low energy consumption, high heat imitate, have anti-seismic performance, automobile electrothermic food and drink device rational in infrastructure to become a kind of electric equipment products of popular style, serve the automobile driver of day and night hurrying back and forth.

For achieving the above object, the utility model automobile electrothermic food and drink device is made up of food box, goblet, thermal conductive cavity, heat-insulation layer, shell, insulation case, magnetic chuck, heating core and circuit part.Food box, goblet are stainless steel products, it with thermal conductive cavity between coincide mutually and active the cooperation; DC low-voltage is adopted in design, and the heating core integral body of low energy consumption is close to thermal conductive cavity, the heat that the energising back produces rapidly equably through thermal conductive cavity to food box, the goblet transmission is fully heated Food ﹠ Drink and is carried out thermostatic control by circuit part; With the anti-flaming thermal-insulation material is heat-insulation layer, utilizes the heat reflection and the insulation case of metal wall, makes heat efficiency be able to abundant raising; Jolt with resistance and shake at electrical equipment bottom dress magnetic chuck, the moulding of design integration closed shell makes full use of the finite space of operator's compartment, in the hope of low energy consumption, and the effect that high heat is imitated.Make and be adapted to various vehicles.

Owing to adopted said structure, power consumption of the present utility model is lower than the automobile micro-wave oven significantly, and the power consumption of micro-wave oven is more than 500W, and the design's product power consumption only is 64W-96W.The utility model does not need inverter, and product structure is simple, and cost is low, is easy to popularize.Compare with " multi-function health-care electric heating mess tin " with market product " driver is happy ", external form uniqueness of the present utility model can be fit to be installed in the operator's compartment of various vehicles, its bottom sucker that is magnetic, can firmly be adsorbed on irony plane or the location iron plate, can prevent the multiple and vibrations in top by actv..Its purpose made heating core conducts heat fast and even, under good heat-retaining condition, reach low-power consumption, the requirement that high heat is imitated, because the modeling structure that gears to actual circumstances, the utility model can heated food, again can heated beverage, also can fast hot food, and continuous constant temperature work, because the material improvement of food box can meet hygienic requirements.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
