Description

Little electric heating food antistaling box

The utility model belongs to field of electric heating, particularly hot fresh-keeping case and table-ware disinfection.

Present disclosed food preservation unit is a lot, be common in cold fresh-keeping be refrigerator, refrigerator-freezer, in fact cold preservation device is applicable to a food (giving birth to product), for secondary food (ripe product), hot fresh-keeping is more convenient edible and meet sanitary standard, McDonald's food that people are familiar with, openly proposing tasty food temperature is respectively 4 degree and 70 degree, the food of 4 degree particularly beverage can be stored in refrigerator, could the food of 70 degree be stored in hot case? the competition of external refrigerator industry particularly rises and do not allow to make with freon again 2000 Christian eras is the restriction of the refrigerator of cold-producing medium, makes the transition of external refrigerator factory produce the hot fresh-keeping case.But the time that external hot fresh-keeping case has adopted 170W power to be warmed up to 70 ℃ needs 70 minutes, the food people of China do not popularize as yet to bread, hamburger, hot drink and beef yet, Chinese's custom is drunk boiling water, and Chinese market need meet the hot food freshness-keeping box of China's actual conditions.

The purpose of this utility model is to design a kind of quick heating, power-saving, can have little electric heating food antistaling box that tableware is killed the bacterium sterilizing function and can conveniently be obtained boiling water concurrently.

Little electric heating food antistaling box is characterized in that being made up of housing 1, soft-touch control plate 2, hot fresh-keeping chamber door 3, hot fresh-keeping case 4, water boiler 9, and hot fresh-keeping case 4 fuses with hydrophone 9; On the hot fresh-keeping case left and right sides housing paired groove 5 being arranged, is safety power source plug socket for inserting micro-electric hot plate 14,6.Thermo electric material is little electric heating stone paper element, and it is to be clipped in the double-deck mica paper, is close to the medial surface and the last bottom surface of housing.The plastic injection-moulded shaping of shell 1 usefulness or with the plastic-coated metallic plate or use the corrosion resistant plate drawing, inner-wall material adopts aluminium skin or the stainless steel sheet| of crossing through oxidation processes, fill full heat proof material between its inside and outside shell wall, as the polyurethane expanded material or the silicate fiber of rock wool, flame-proof heat-resistant.Micro-electric hot plate 14 adopts stainless steel to make, two essential all around welding that clamp little heating and auxiliary are firm and tight-closed, 15 is little electric heating stone paper element, 16 is insulating mica plate, gripping 16 of two geometry unanimities of 15 must reach more than 2 millimeters greater than 15 by periphery, 17 is metal foil paper, and 17 will clamp 15 two-layer 16 full bags.Can play absolute exhausted water effect,, can ensure that still steam can the little heating 15 of etch and leak electricity even 14 periphery splits.By the incorporated micro-electric hot plate of 14,15,16,17 closed group, must be strong and stand above place behind the tableware still not crooked.Usually only need to post little heating, only under the situation of capacity, just at the rearmounted little heating of the medial surface or the interior back side than big or the special height of hot fresh-keeping temperature (130 ℃) in the bottom surface and the end face metal skin back of hot fresh-keeping chamber interior wall.18 is little electric heating face, and its preparation method has patent of invention 88100015.9, is called for short the patent of invention of D2R.19 is electrode, adopt heatproof conductive silver paste coating back oven dry system or; 20 is electrode, and it is fixing to adopt silver-plated weld tabs to be riveted on 19, and pair of electrodes 20 connects fire, ground wire or the both positive and negative polarity of power supply respectively; 21 expressions are from the 20 soft power lines of drawing.7 are the key button that discharges water, and press 7, and boiling water can flow out from faucet 8, and 9 be the heat storing type electric water heater, in the heat storing type electric water heater of known technology is arranged, 9 bottom glass is located for putting, and can put into cup.The hot fresh-keeping case also can be made up of bilayer, and 10,11 is respectively the chest and the big cabinet door of double-deck hot fresh-keeping case, and cabinet is the hot case of excellent heat insulating performance as shown in Figure 1 behind the door.The favourable storage heat of the hot fresh-keeping case of this pair of cabinet is with using electricity wisely, and also favourable function allocation, common chest are as hot fresh-keeping, and big cabinet has hot fresh-keeping or table-ware disinfection function concurrently.Heat up when being elected to be the hot fresh-keeping function and keep 70 ° of constant temperature, be warming up to 125 ℃ of lasting insulations when being elected to be the table-ware disinfection function and close electric heat source automatically after 15 minutes, during as the table-ware disinfection function micro-electric hot plate is inserted the effect that does not make micro-electric hot plate electric heating in 5 and only be used as gripper shoe, to increase the seasoning amount of tableware; 12 is the cabinet door-hinge, and 13 is feet, has screw usually and is rotated with at the bottom of cabinet and utilizes screw fine setting antistaling box to be in level.

The utility model has the advantages that economize on electricity, quick heating, hot fresh-keeping or heat sterilization effective, can not scald the people, in the hot fresh-keeping process, can not damage the low molecular nutrition composition in the food, hot uniformity height, health civilization in the casing, particularly fresh-keeping degree high and with hot fresh-keeping with lump together for the boiling water device, be fit to China's actual conditions, every performance all is better than external hot fresh-keeping case, and this hot fresh-keeping case can be placed on automobile or the train and to be suitable for the work of various low voltage and direct current bottle, can also use the district work at no civil power of low tension that wind-driven generator provides.
