Abstract
A small household electrical appliance with low energy consumption, rapid heating up, high thermal efficiency, and food nutrition maintenance function --a far infrared radiation energy conservation heating lunch box, in which the infrared radiation ceramics coating is stimulated by electrical energy to radiate infrared ray internal box, is used for heating up the food in the box. The product shape and structure can be seen the instruction booklet abstract attached figure 1. The lunch box contour is like a cuboid. The box body is made of high quality aluminum alloy or stainless steel plate. The box consists of an external layer (1), an inner layer (2), a roof panel (3), a resistance wire (4) and electric control equipment (5), (6), (7), (8). The inner and the outer layers build up to sandwich, the layer is loaded with the resistance wire (4), a MgO insulation coating and a far infrared radiation ceramics coating are applied on the surface near to the resistance wire. A MgO, ZrO2 ceramic insulator heat insulation coating is applied on internal surfaces of the outer layer (1) and the roof panel (3). A three-phase power source plug (5), a transformer (6), a warm control (7) and an automatic power failure equipment (8) are connected outside the box.
Description
Affiliated technical field
Small household appliances.
Background technology
At present, the heat exchange pattern of small household appliances heater mainly is that its shortcoming is that power consumption is big, heat loss is big, heat time heating time is long, the thermal efficiency is low by Convective Heating, destroys food nutrition.Though micro-wave oven slightly improves, but its power consumption is high, volume is big, inconvenience is carried.
Summary of the invention
With food in the FAR INFRARED HEATING lunch box.
The technical scheme that its technical problem that will solve the utility model adopts is: the current heating resistor silk excites coatings capable of preventing from far infrared radiation infrared radiation in box in the interlayer, food in the heating box, and the nutrition that keeps food.Attemperating unit is used to regulate temperature in the box.Temperature is too high, the breaker device insulation of cutting off the power supply automatically.
The beneficial effects of the utility model are that radiation does not need heat transfer medium with light velocity directive foodstuff surface, so energy loss is little, it is fast to conduct heat; Because electromagnetic wave has certain penetration capacity, therefore, material is heated evenly, and does not destroy the nutrition of food; Its energy-efficient performance is far above general electric heating device; And volume is little, easy to carry.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the master of the energy-saving heating lunch box of far infrared radiation embodiment looks cutaway view.
1. skins among the figure, 2. internal layer, 3. top cover, 4. resistance wire, 5. three phase mains plug, 6. transformer, 7. attemperating unit, 8. auto-power-off device
The specific embodiment mode
Lunch box is the cuboid with interlayer among the figure.Outer (1), internal layer (2), top cover (3) is the fine aluminum alloy or stainless steel materials is made.Resistance wire (4) is housed in the interlayer, and internal layer (2) scribbles MgO coatings and far infrared radiation ceramics coating near the plate face of resistance wire.Resistance wire energising back produces heat energy, passes to internal layer (2), excites far infrared radiation ceramics coating infrared radiation in container on internal layer (2) surface, is used for the food in the heating container.The inner surface of outer (1), top cover (3) scribbles MgO, ZrO2 ceramic insulation insulating moulding coating.Box is connected with three phase mains plug (5) outward, and electric current is by transformer (6) (220V～60V), connect resistance wire (4), and access temperature control (7) and auto-power-off device (8).
Claims (3)
1. energy-saving heating lunch box of far infrared radiation, the feature that these small household appliances have is: cuboid interlayer lunch box.
2. the energy-saving heating lunch box of far infrared radiation according to claim 1 is characterized in that: resistance wire is housed in the interlayer.
3. the energy-saving heating lunch box of far infrared radiation according to claim 1 is characterized in that: the internal layer surface by resistance wire scribbles MgO coatings and far infrared radiation ceramics coating, and inner surface outer, top cover scribbles MgO, ZrO
