The specific embodiment

Shown in Fig. 1-6, chest is made of the casing that the end is arranged and case lid two parts, among the figure as seen, position corresponding to the pressure cooker handle on casing and the case lid all has handle hole, the size in hole is consistent with the handle of pressure cooker, tight as far as possible contact is in order to avoid heat influences heat insulation effect from loss too much here.

Even ordinary pan strengthens firepower, water temperature is risen to more than 100 ℃.Because nearly all being used on the heat of evaporation of moisture, the heat that adds (under 1 atmospheric state, to allow 1 gram water evaporation need 2261 joules heat).Moisture evaporated, volumetric expansion become steam and are emitted in the air to the degree that can start pot cover.

When in a single day 1 cubic centimetre water (liquid) becomes steam (gas), volume can be expanded to 1700 cubic centimetres, and water can seethe with excitement when being warmed to 100 ℃ under 1 atmospheric pressure.

And pressure cooker is different with ordinary pan, and pressure cooker utilizes fixed cover such as bolt, has the construction features that do not allow steam distribute.The steam that is closed in other words can make the pressure in the pot rise.

The boiling point of material is along with pressure rises.For example when 4 atmospheric pressure, the boiling point of water (temperature of boiling) can rise to 150 ℃.During the working pressure pot, along with the rising of internal pressure, boiling point can be raised to 110 ℃～150 ℃ at leisure from usual 100 ℃.That is to say, use identical water, because boiling point rises, so the food that originally is difficult for boiling also can boil fully.

When using two build energy-saving heat preserving casees shown in Fig. 1-6, when the pressure cooker internal pressure rises, when temperature reaches the 130 degree left and right sides it is put into pressure cooker energy-saving heat preserving case, its internal temperature will remain on degree more than 100 at 20 to 60 minutes kettle temperatures, that is to say and need not also can boil fully by any energy food.

Being depicted as Trisomy energy-saving heat preserving case as Fig. 7-15, is exactly to be three parts separately at the bottom of casing, case lid and the case.The structure of its handle hole is identical with two builds.Can put into casing to pressure cooker, cover case lid and heat together,, remove thermal source when temperature reaches the 130 degree left and right sides when the pressure cooker internal pressure rises, be placed on it at the bottom of pressure cooker energy-saving heat preserving case on (also can continue to be placed on the cooker), energy-saving effect is better.

More than the chest material therefor of two kinds of structures distinguish to some extent according to different grades.Simple type use plastic foam; The usefulness of durable type: plastic foam, the mineral wool goods, perlite, and plate with metals such as plastics or aluminium or nonmetallic materials outside.

Fabrication scheme is as follows:

1) simple type: simple type pressure cooker energy-saving heat preserving case can be with two kinds of technology manufacturings, first kind is adopted full foam process, and this pressure cooker energy-saving heat preserving case production cost low (about ternary), manufacturing process are simple, but service life is short, can be directly as producing packing, a thing dual-purpose.Second kind is used the structural foamed plastic technology, and not foaming with core layer foaming, cortex is feature, outer hard interior tough, specific strength (in the intensity of unit mass) height, production cost higher relatively (about five yuan), manufacturing process relative complex, but long service life.

2) durable type: plastic foam, mineral wool goods,, insulation materials such as perlite are the internal insulation material, metal such as plastics or aluminium or nonmetallic materials are outer packaging.Production cost higher (about 15 yuan), manufacturing process complexity, but long service life is attractive in appearance.

The chest of these two kinds of patterns is through on probation, and the energy-saving effect life shows, and safety saves trouble, makes things convenient for, and liked by the trier.
