Abstract
The utility model relates to a food heat preservation cover which can automatically control temperature, which comprises a cover casing 2, a heat preservation layer 3 and a heat conduction layer 4. A temperature auto-controlling electric heating band 1 of the heat preservation cover is arranged between the cover casing 2 and the heat conduction layer 4 and is connected with the heat conduction layer 4 in the mode of glue adhering connection, and a power supply is also connected with the temperature auto-controlling electric heating band. The bottom of the heat preservation cover is also provided with a heat preservation board 5 which is provided with a temperature auto-controlling electric heating band 6 of the heat preservation board, wherein the heat preservation board 5 comprises a heat conducting plate 7, a heat preservation layer 8, a bottom plate casing 9 and the temperature auto-controlling electric heating band 6 of the heat preservation board which is connected with the inner wall of the heat conducting plate 7 in the mode of glue adhering connection. The electric heating band materials are adopted by the utility model to preserve and control the temperature. The utility model has the characteristics as follows. Firstly, the heating temperature can be automatically limited, the heat inertia is small, the temperature is uniform, and the utility model can not over the temperature and be overheated and without the consideration of burning out, so a temperature controlling device needs not to be arranged. Secondly, the power and the heating area of the electric heating band is directly proportional to the length and the thickness and can arbitrarily intercepted, or the electric heating band can be arbitrarily extended within limited length. Thirdly, the utility model has the advantages of high safety, energy saving, convenient operation and maintenance.
Description
Technical field
The utility model relates to daily technical field of living goods, is a kind of from temperature control food stay-warm case.
Background technology
Burned dish, various delicious earlier, the time just can turn cold a little while, and twice-cooked stir-frying is burnt to fry and is cooked again, color, smell, taste and shape are all greatly inferior, food taste variation not only, and nutrition also can run off in a large number, how with burned dish, various delicious insulation earlier, this is the problem that people endeavour to solve all the time.Electric heating thermal insulation cover of the prior art is many with electrical heating wire, radiator valve, aluminium sheet heating layer, foam insulation, and plastic shell constitutes, complex structure, and the cost height, easy break-down is difficult for applying.
Summary of the invention
The purpose of this utility model provide a kind of cost low, make simple, non-maintaining, high insulating effect from temperature control food stay-warm case.
Described from temperature control food stay-warm case, comprise case 2, heat-insulation layer 3, heat-conducting layer 4, it is characterized in that: between case 2 and heat-conducting layer 4, be provided with stay-warm case self temperature control heating tape 1, described stay-warm case self temperature control heating tape 1 and 4 gluing connections of heat-conducting layer, stay-warm case self temperature control heating tape 1 also is connected with power supply through plug; Also be provided with the warming plate 5 of band warming plate self temperature control heating tape 6 in the bottom of stay-warm case.Described warming plate 5 comprises: heat-conducting plate 7, heat-insulation layer 8, bottom plate shell 9, warming plate self temperature control heating tape 6, and warming plate self temperature control heating tape 6 is connected with the inwall of heat-conducting plate 7 is gluing, and warming plate self temperature control heating tape 6 also is connected with power supply through plug.
Described self temperature control heating tape adopts the conductive material that can sense temperature changes, and then changes self form, reaches temperature controlling function.
Its structure is seen Fig. 2, and extrusion molding conductive material equably between two parallel metal wires wraps one deck insulating materials outside again as sheath.
Its action principle: after power supply was connected in the ribbon heater, electric current formed loop through conductive material to another root lead by a lead, and material is heated up.Its resistance makes resistance increase to the degree of almost blocking electric current rapidly along with after temperature rises to certain value, and its temperature no longer raises, and can export corresponding power according to environment temperature.
The utility model has adopted ribbon heater material insulation temperature control, and the characteristics that have are: 1, volitional check heating-up temperature, and thermal inertia is little, and temperature is even, can over temperature and heat, there is not the worry of burning, need not be equipped with temperature regulating device.2, the power of ribbon heater and heating surface (area) (HS are directly proportional with length, thickness; Temperature-resistant, be inversely proportional to electrode distance, so intercept arbitrarily, or within certain-length spreading arbitrarily.3, safe, energy-conservation, working service convenience.
The beneficial effects of the utility model are: simple in structure, exempt from non-maintaining, high insulating effect, safe, energy-conservation, be suitable for family, catering trade is used.
