Abstract

The utility model discloses a drop water evaporization inner circulation pressure cooker, which is composed of a cooker body, a cooker cover, a sealing ring, handles and a spring safety valve of the existing pressure cooker and a water dropper, a steam communicating tube and an evaporization disc with meshes which are all additionally provided. In the process of cooking food, steam pressure in the cooker is utilized for controlling water in the water dropper to drop on the cooker cover for carrying out evaporization and taking heat transmitted from the inside of the cooker away, the steam in the cooker forms a circulation from evaporization to condensing and then from condensing to evaporization, and the steam pressure is balanced within a definite range. Because no steam is exhausted from the inside of the cooker, the health protection, convenience and safety of the utility model can be enhanced.

Description

Drop water evapourising inner circulation pressure cooker

The utility model relates to a kind of internal-circulating pressure cooker of the vaporization of dripping outside pot, be applicable to food cooking.

Existing known pressure cooker in order to limit steam pressure in the pot, must be discharged a large amount of steam, thereby produce following shortcoming in the cooking food process in pot: 1. the nutrition in the food is discharged lostly with steam, is unfavorable for keeping the nutrition in the food; 2. the harmful concentrate and the incrustation scale that are evaporated in the moisture content are retained in the food, are 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 utility model is: overcome the shortcoming of existing pressure cooker, a kind of internal-circulating pressure cooker of the vaporization of dripping outside pot is provided, the steam that produces in the pot in the cooking process is not discharged outside the pot, only form the circulation of vaporization → condensation → vaporization in pot.

Task of the present utility model is achieved in that on the basis of pot body, pot cover, handle, sealing ring and the spring loaded safety valve of existing pressure cooker increases water-dropper, logical steam pipe and mesh gasifying disk, logical steam pipe is installed in the center of pot cover, water-dropper is mounted on the logical steam pipe, and the mesh gasifying disk is pressed on the pot cover by logical steam pipe; A water tumbler is arranged on the water-dropper, and the body cavity in the middle of the water tumbler has a cone valve to block valve opening, and there is a pressure-sensitive diaphragm lower end of cone valve, the steam pressure in the pot through logical steam pipe act on pressure-sensitive diaphragm below; When elastic force that the steam pressure below acting on pressure-sensitive diaphragm is set up greater than spring, promote pressure-sensitive diaphragm and up move, back down cone valve, make water in the water tumbler flow out to drip on the pot cover and vaporize by valve opening, pot in the heat that spreads out of take away.

Below in conjunction with accompanying drawing the utility model is elaborated:

Figure (1) is a schematic diagram of the present utility model.

Figure (2) is water-dropper of the present utility model, logical steam pipe and the mesh gasifying disk cutaway view during no steam pressure state in pot.

The utility model is by water-dropper (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, the upper end of logical steam pipe (2) is conical, be fastened on the center of pot cover (4) with porous nut (17), water-dropper (1) is mounted on the logical steam pipe (2), there are many apertures to be pressed on the pot cover (4) on the mesh gasifying disk (3) by logical steam pipe (2), after mesh gasifying disk (3) left rotation and right rotation one angle (30 °～90 °), utilize groove and flanged structure on logical steam pipe (2) and the mesh gasifying disk (3) to take out down or precession from logical steam pipe (2); There is a water tumbler (13) to use thread connection on valve body (14) on the water-dropper (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) lower end of cone valve (10), 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 (15) 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), drip on the following pot cover (4) of mesh gasifying disk (3), because the high temperature on the pot cover (4), the water that drips is by vaporization rapidly (shown in the outer arrow of figure (1) pot), take away a large amount of heats, high-temperature steam in the pot is passed to pot cover (4) to heat again and is carried out heat exchange, be condensed into water after the high-temperature steam heat release and fall (shown in arrow in figure (1) pot), 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, only forms the circulation of vaporization → condensation → vaporization in pot, and the steam pressure in the pot is limited to the pressure limit that spring (11) is set up, hollow cylinder permanent magnet (12) is used to produce magnetized drinking water, prevents incrustation scale; After the water droplet in the water tumbler (13) was intact, the steam pressure in the pot continued to raise, jack-up water-dropper (1), steam through the inner chamber of via hole (18), hole (20) and valve seat (16) from the hole (19) discharge and carry out the pressure limiting warning.

The utility model does not have steam to discharge in pot in cooking process, so produced following advantage and effect; Nonnutritive composition scatters and disappears, and is not evaporated the legacy of moisture content in the food, is difficult for enamelware pot, is good for one's health; As long as in water tumbler (13), continue to add water, can arbitrarily prolong cooking time, convenience is good; The fryer accident of exhaust hole can not take place to stop up because of food residues, and security is good; From breather pipe (2) take off water-dropper (1) on, change the Weight type pressure limiting valve of existing pressure cooker. Its using method is identical with existing pressure cooker with performance.
