Generally, the cooking of food processing is carried out with electrical heating or naked light heating, but such cooking method because of overheated overdo or phenomenon such as burnt takes place easily, and wastes more energy.The cooking method that can address this problem, vegetables of knowing that the life that will cook is earlier arranged or cereal are placed in the soup juice of hot water or boiling and soak, and then will become the half-finished food that has heated and be incubated for a long time, make it become cooking finished product thus.
This insulating cooking pot as shown in Figure 2.
Insulating cooking pot 30 shown in Figure 2 has heat insulation outer container 2 basically, can pick and place the interior pot 3 that is contained in freely in this outer container 2, cover in this inner cap 31 on pot 3, during packing under pots 3 the state with the heat insulation enclosing cover 32 of the closure of openings of outer container 2.On this inner cap 31 handle 33 is housed.
If the interior pot 3 of this insulating cooking pot 30 is taken out, put into material for cooking, cover inner cap 31 or do not cover inner cap, by external heat source from the bottom and/or the side heat, be heated to cook temperature, under the state that is covered with inner cap 31, put into immediately in the outer container 2, cover enclosing cover 32, like this, owing to prevented that heat from diffusing outside outer container 2, thereby do not have external heat source can cook yet.
In existing this insulating cooking pot, in gastronomical process, to observe the food of the inside sometimes, perhaps when the cooking is finished, open enclosing cover 32, to catch the handle 33 that is located on the inner cap 31 that the inner cap 31 of interior pot 3 is taken off with hand, but because this handle 33 in the inside of outer container 2, thereby has been heated to high temperature, and also be full of high temperature hot gas so that be incubated on every side, therefore handle inserts and grabs handle 33 at once.
The present invention makes for sort this problem out, its objective is provides a kind of insulating cooking pot, and it is to keep its heat-insulating property enclosing cover 32 can be opened again and immediately and safely inner cap 31 be taken off from being in the interior pot 3 that is heated under the hot environment.
The insulating cooking pot of the present invention of making in order to achieve the above object has heat insulation outer container, can pick and place the interior pot that is contained in freely in this outer container, cover the inner cap on the interior pot and under the state that the interior pot that is covered with inner cap is put into the heat insulation enclosing cover of the closure of openings of above-mentioned outer container; In above-mentioned, cover and be provided with handle, and be configured to make the opening than above-mentioned outer container under the state of the interior pot that is covered with inner cap being put into outer container of upper end at least of this handle also outstanding upward.This handle is synthetic resin article preferably.
The thermal insulation layer of the outer container that this is heat insulation preferably the vacuum interlayer wall construction vacuum heat-insulating layer or contain the thermal insulation layer of heat-barrier material.
Because the upper end at least of handle opening than above-mentioned outer container under the state of the interior pot that is covered with inner cap being put into outer container is also outstanding upward, thereby when opening enclosing cover, does not need handle to inject in the hot environment and just can catch handle.Owing to this handle is arranged to also more outstanding upward, thereby opens enclosing cover and just can make it touch the cold air of outside and cooling fast, again so can go to touch it with hand immediately than the opening of outer container.
Fig. 1 is a most preferred embodiment of expression insulating cooking pot of the present invention.In the following description, the structural detail every and conventional example that had illustrated with Fig. 2 is identical all puts on same label and omits explanation to it.
Among Fig. 1, this insulating cooking pot 1 have the vacuum heat-insulating layer that the vacuum interlayer wall construction is arranged heat insulation outer container 2, can pick and place the interior pot 3 that is contained in freely in this outer container 2, cover in this inner cap 4 on pot 3, be covered with under the state of interior pot 3 of inner cap heat insulation enclosing cover 5 in threading opening 8 sealings of outer container 2.
Cover inner cap 4 on interior pot 3 and be heat-resisting plastic, the outside forms the shape of protruding that slightly is sphere, its circumference can be covered with the edge part of the opening of interior pot 3 with engaging, in addition, insert the central portion that logical screw 7 is mounted and fixed on plastic handle 6 inner cap 4 by inboard from inner cap 4.
The interior pot 3 that is covered with inner cap is being installed under the state of certain position outer container 2 in quite deeply, and the upper end 6a that the height of the height that is protruded by the dome shape of inner cap 4 and handle 6 itself make this handle 6 be configured to it also gives prominence to upward than the opening 8 of outer container 2.
In addition, form the recess 9 of the upper end 6a that can hold handle 6 at least at the inside part of the correspondence of enclosing cover 5, so that under above-mentioned state, handle 6 is unlikely to contact with the inboard of enclosing cover 5 when covering enclosing cover 5.
If put into material for cooking after interior pot 3 taking-ups with this insulating cooking pot 1, cover inner cap 4 or do not cover inner cap ground and its bottom is heated by external heat sources such as stoves, the food of the inside is heated to cook temperature, under the state that covers inner cap 4, put in the outer container 2 immediately, cover enclosing cover 5 again, outwards disperse from outer container 2 owing to can prevent heat, thereby can proceed not have boiling of external heat source and stew the cooking.
In the time will opening inner cap 4 for observe or take out in pot 3 food in heat insulation gastronomical process or when finishing, because the upper end 6a of handle is also more outstanding upward than the opening 8 of outer container, thereby the cold air of handle 6 contact outside and cooling rapidly, and hand just need not be placed in the hot environment in the outer container 2 can horse back and catch handle 6 safely.
The outer container 2 of this embodiment is made of vacuum heat-insulation container 12 and the bottom member 13 that is formed by synthetic resin etc. that is contained in its bottom, the vacuum heat-insulation container makes the vacuum interlayer wall construction, to be the inner core that bottom tube-like is arranged 10 that will be made by metals such as stainless steels and diameter be bonded into one than the portion of peristoma separately of its big slightly urceolus 11 for it, and the air between the inner/ outer tube 10,11 discharged and the steam vent sealing formed the vacuum heat-insulation space layer from the base bleed hole.In addition, in the outer edge of the opening 8 of vacuum heat-insulation container 12 the outer container handle 14 that is formed by synthetic resin etc. is housed.
The part of container handle 14 is provided with linkage 15 outside, enclosing cover 5 can be installed in to free folding it above.On the outer container handle 14 of a side relative, be provided with stop mechanism 16, be used for when enclosing cover 5 is closed, it being pinned with linkage 15, in the time will opening enclosing cover 5, promptly can be by pushing downwards with lock release.
