Abstract
The utility model discloses a heat balance heating hand-held cooker, which comprises an insulating casing body, a heat-insulating cover, and a water jacket. The utility model is characterized in that the water jacket is a cylindrical body, and the outside diameter thereof is a little smaller than the inner diameter of the insulating casing body; the upper end surface of the water jacket is provided with more than one water injecting hole, and an enclosed plug is plugged in the water injecting hole to prevent water in the water jacket to overflow. The water jacket is arranged inside the insulating casing body. When the utility model is used, hot water is injected inside the water jacket, food is arranged inside the hand-held cooker, and the heat-insulating cover is covered on the hand-held cooker; heat of the hot water can be transferred to the food via the wall of the water jacket, and the temperature of the food can be increased to reach the heat balance; the holding time can be prolonged, and the freshness can of the food can be kept; in addition, cold rice and dishes can be placed in the utility model to increase the temperature of the food for eating.
Description
The utility model relates to a kind of cool-bag, and particularly relating to a kind of skin is insulated case, in establish hot water jacket, in hot water jacket, inject boiling water, make and deposit food in the pot and heat up, to prolong the cool-bag of its temperature retention time.
The cool-bag kind is a lot of at present, but the common drawback that exists is the temperature retention time weak point.In addition, the long-time splendid attire of food is behind cool-bag, and just cooling is cooled off, and the steam in the container condenses into the globule because of cooling, soaks food, and the food mouthfeel is degenerated, and the forfeiture freshness.
Present cool-bag manufacturer, mainly be that the performance of taking to improve the shell body heat-barrier material prolongs temperature retention time, after but the food cooking is finished, in this section of cool-bag period of packing into, food is lowered the temperature significantly, therefore the heat-barrier material performance is good again, and temperature retention time also can not prolong a lot.
The purpose of this utility model is at the problems referred to above, and a kind of effectively food and extend temperature retention time is provided, and the thermal balance of maintenance food freshness that can be good is heated and carried pot.
The purpose of this utility model adopts following technical proposals to realize, that is:
Thermal balance is heated and is carried pot, comprises insulated case, adds thermofin, insulation cover and handle.Insulated case is a cylindrical body, top end opening.Adding thermofin is water jacket, and water jacket is cylindrical body, and its external diameter is slightly less than the internal diameter of insulated case, and in the insulated case of can packing into.1 above water injection hole is arranged on the water jacket upper surface, behind the injection boiling water, on water injection hole, fill in closing cock, in the water jacket in order to avoid water is excessive.The inner space of water jacket is moist closet A.Water jacket is made by the metallic plate of good heat conductivity.But filled heat insulating material between the inner and outer shell of insulation cover is as foaming PU heat-barrier material, crushed crude pearlite etc.The two ends of carrying handle are separately fixed on the outer wall of water jacket.But the insulation cover driving fit is on the upper port of insulated case.
Another kind of embodiment of the present utility model, being water jacket is made of inwall and flanged cylindrical body of insulated case, the outer face of the flange of flanged cylindrical body contacts with the inwall of insulated case, and watertightness solid welding connection, and 1 above hand-hole is set on flange.Form the water jacket that to adorn hot water between insulated case inwall and the flanged cylindrical body.The closing cock of this embodiment is fixedly arranged on the insulation cover.
The shape of insulated case of the present utility model and insulation cover is not only cylindrical body, also can be style novel shape such as square body, polygonal body.
During use, hot boiling water is injected in the water jacket from water injection hole, filled in closing cock, the well-done food of will cooking a meal is placed in the moist closet or in packing into and puts into moist closet again in the pot, covers insulation cover.Though the food temperature has reduced therebetween, the hot water in the water jacket raises food temperature, and reaches thermal balance by the heat conduction.Adopt this structure can prolong temperature retention time and maintenance food freshness greatly.The utility model can also be used as a kind of thermos-cooker and other heat preservation food.
Fig. 1 is the insulated case structural representation of a kind of embodiment of the present utility model, and Fig. 2 is the jacket structure for water schematic diagram that handle and interior pot are housed, and Fig. 3 is the insulation cover structural representation, and Fig. 4 is second kind of example structure schematic diagram of the present utility model.
The drawing reference numeral explanation:
1 is that insulated case, 2 is cylindrical body for flange, 12 for foaming PU heat-barrier material, 11 for insulation cover, 10 for inner pot cover, 9 for interior pot, 8 for handle, 7 for closing cock, 6 for water injection hole, 5 for water jacket, 4 for inwall, 3.
The utility model is described in further detail below in conjunction with accompanying drawing.
Thermal balance is heated and is carried pot, comprises insulated case 1, insulation cover 9, handle 6 and the interlayer of heating.The interlayer of heating is a water jacket 3, and 2 water injection holes are arranged on the upper surface of water jacket 3, all is plugged with closing cock 5 on water injection hole.Water jacket 3 is a cylindrical body, and its external diameter is slightly less than the internal diameter of insulated case 1, and water jacket 3 can be put into insulated case 1.The inner space of water jacket 3 is moist closet A.The two ends of handle 6 are separately fixed on the outer wall of water jacket 3.Insulated case 1 is a cylindrical body, vacuumizes between the inside and outside wall of insulated case 1, to improve its heat-proof quality.Filling foaming PU heat-barrier material 10 between the inner and outer shell of insulation cover 9.
During use, hot boiling water is injected in the water jacket 3 from water injection hole 4, and fill with, on water injection hole 4, fill in closing cock 5 again.In the pot 7, cover inner pot cover 8 in cooking food packed into, interior pot 7 is put into the moist closet A of water jacket 3.At last water jacket 3 is put into insulated case 1 (also can earlier water jacket 3 be put into insulated case 1), covered insulation cover 9.
Because the heat-insulating property of insulation cover 9 and insulated case 1 is very good, when insulation cover 9 driving fits during in the upper port of insulated case 1, the insulated case inner space just forms the confined space of an adiabatci condition, because water jacket is to make with the good metallic plate of thermal conductivity, therefore the boiling water heat can be passed to food, promptly borrow the temperature of hot water in the water jacket to improve the temperature of food, and prolong its temperature fall time, reach heat insulation effect.The utility model not only can prolong temperature retention time, and condenses into water droplet owing to the steam of cool-bag inside is not easy the Yin Wendu cooling, more can keep the freshness of food good to eat.
Another kind of using method of the present utility model is cold meal, cold dish directly can be put into this fireless cooker, injects boiling water then in water jacket, utilizes the temperature heat food of boiling water.In addition, also can directly put into this fireless cooker, it is used as water drum as stewing pot or with it after need fricassee putting into pan boiling and boiling.
Second kind of embodiment of the present utility model is that water jacket 3 is an overall structure with insulated case 1, promptly is made of the inwall 2 of insulated case 1 and the cylindrical body 12 of flanged pin 11, and the outer face of flange 11 contacts with inwall 2, and the watertightness solid welding connects.2 water injection holes 4 are arranged on flange 11.The 2nd characteristics of second kind of embodiment be 2 closing cocks 5 be fixed on the insulation cover 9 with 2 water injection holes, 4 corresponding positions on.
