Abstract

The invention discloses a kind of internal-circulating cooking method and a kind of internal-circulating pressure cooker, compare with existing cookery and existing pressure cooker, its advantage is: the high-temperature steam that is enclosed in the cooking process in the pot is not discharged outside the pot, and only in pot, vaporize → circulation of condensation → vaporization, thereby have more health, convenience and security, as required, internal-circulating cooking method and internal-circulating pressure cooker can convert existing cookery and existing pressure cooker again easily to.

Description

Internal-circulating cooking method and internal-circulating pressure cooker

The present invention relates to a kind of interior circulation cooking methods and a kind of internal-circulating pressure cooker of realizing this method that is applicable to cooking.

Existing known food cooking method is: the steam of the water generates of the boiling of being heated in the pot must be discharged outside the pot, so existing known pressure cooker is in cooking process, in order to limit the pressure in the pot, also must discharge a large amount of steam, the common drawback of existing cookery and existing pressure cooker is: 1, the nutrition in the food is discharged with steam and is scattered and disappeared, and is unfavorable for keeping the nutrition of food; 2, the harmful ion concentrate that is evaporated in the moisture content is retained in the food, is unfavorable for health; 3, the moisture content in the pot is discharged with steam and is reduced, easily enamelware pot; 4, can not arbitrarily prolong cooking time; 5, exhaust hole is stopped up by the food slag easily, and the fryer accident takes place.

Task of the present invention is: the common drawback that overcomes existing cookery and existing pressure cooker, create a kind of new internal-circulating cooking method and a kind of internal-circulating pressure cooker of realizing this method, the steam that produces in the cooking process is not discharged outside the pot, and only in pot, vaporize → circulation of condensation → vaporization.

Task of the present invention is to realize like this, internal-circulating cooking method is: after the high-temperature steam pressure in being enclosed in pot reaches certain pressure, utilize interior cooling fluid of the outer container of this pressure control pot and the high-temperature steam in the pot to carry out heat exchange, the high-temperature steam liberated heat is taken away, be condensed into water after the high-temperature steam heat release again, steam pressure in the pot is reduced, the vaporization of in pot, being heated again of condensed water, the steam that produces in the pot in the cooking process is not discharged outside the pot, and only vaporizes in pot → circulation of condensation → vaporization; Internal-circulating pressure cooker is to increase flow controller, logical steam pipe and mesh dish on the basis of pot body, pot cover, sealing ring, handle and the spring loaded safety valve of existing pressure cooker, logical steam pipe is installed in the center of pot cover, flow controller is mounted on the logical steam pipe, and the mesh gasifying disk is withheld on pot cover by logical steam pipe; A water tumbler is arranged on the flow controller, and the body cavity in the middle of the water tumbler has a cone valve, and a spring is depressed cone valve and blocked valve opening, and there is a pressure-sensitive diaphragm lower end of cone valve, the steam pressure in the pot through logical steam pipe can act on pressure-sensitive diaphragm below.

Below in conjunction with accompanying drawing embodiments of the invention are elaborated:

Figure (1) is the principle schematic of internal-circulating cooking method of the present invention.

Figure (2) is the flow controller of internal-circulating pressure cooker of the present invention, logical steam pipe and the mesh gasifying disk cutaway view (pot body and other part are not drawn) during no steam pressure state in pot.

Shown in figure (1), in the cooking process, be enclosed in the pot in a high-temperature steam reach rated pressure after, cooling water flow out of in the steam pressure control flow controller (1) fallen on the pot cover (2), high-temperature steam in the pot carries out heat exchange by pot cover (2) and the water that flows down, make water on the pot cover (2) vaporize rapidly (shown in the outer arrow of pot), the heat that high-temperature steam spreads out of is taken away, be condensed into water after the high-temperature steam heat release again and fall (shown in arrow in the pot), pressure in the pot is reduced, the water that the falls vaporization of being heated again, like this, the steam that produces in the pot is not discharged outside the pot, and only vaporizes in pot → circulation of condensation → vaporization, and the interior steam pressure of pot also just is limited at certain pressure limit.

As figure (1), (2) shown in, internal-circulating pressure cooker is by flow controller (1), logical steam pipe (2), mesh gasifying disk (3), pot cover (4), sealing ring (5), handle (6), pot body (7) and spring loaded safety valve (8) are formed, logical steam pipe (2) upper end is conical, be fastened on the center of pot cover (4) with porous nut (17), flow controller (1) is mounted on the logical steam pipe (2), the mesh gasifying disk has many apertures on (3), withheld on pot cover (4) by logical steam pipe (2), after mesh gasifying disk (3) left rotation and right rotation one angle (30 °-90 °), utilize groove and flange button limit on logical steam pipe (2) and the mesh gasifying disk (3) under logical steam pipe (2), to take out or to tip in; There is a water tumbler (13) to use thread connection on valve body (14) on the flow controller (1), the inner chamber of valve body (14) has a cone valve (10), nut (9) compression spring (11), spring (11) is depressed cone valve (10) and is blocked valve opening (22), there is a pressure-sensitive diaphragm (15) cone valve (10) lower end, pressure-sensitive diaphragm (15) is pressed in between the valve body (14) and valve seat (16) of thread connection, the interior steam pressure of pot through via hole (18) and hole (20) act on pressure-sensitive diaphragm (15) below; When elastic force that the steam pressure below acting on pressure-sensitive diaphragm (15) is set up greater than spring (11), promoting pressure-sensitive diaphragm up moves, back down cone valve (10), make water (21) outflow from the hole in the water tumbler (13) through via hole (23) and valve opening (22), fall on the following pot cover (4) of mesh gasifying disk (3), carry out heat exchange with the high-temperature steam in the pot, the steam pressure size in the pot is set up by spring (11), and the hollow cylinder permanent magnet is used to produce magnetized drinking water and prevents incrustation scale; After the current in the water tumbler (13) are intact, steam pressure in the pot can continue to raise, jack-up flow controller (1), steam through the inner chamber of via hole (18), hole (20) and valve seat (16) from the hole (19) discharge and carry out pressure limiting and report to the police, continue arbitrarily to prolong cooking time toward water tumbler (13) Nei Jiashui.

There is not steam in pot, to discharge in the process of cooking food, this is of the present invention one big advantage, relatively have more health, convenience and security with existing cookery and existing pressure cooker, in addition, if take off the Weight type pressure limiting valve that flow controller (1) is changed existing pressure cooker, its cooking methods is again identical with existing pressure cooker with existing cookery with performance.
