Abstract

The utility model relates to an energy-saving pot lid with pressure increasing and automatic air exhaust functions. The utility model is formed by the connection of an air exhaust opening and an air exhaust movable cover. When air pressure in a pot does not reach to a certain degree, the air exhaust opening and the air exhaust movable cover arranged on the pot lid are in a closed state to reduce heat loss in the pot; when the air pressure in the pot reaches to a certain degree, the whole pot lid does not move, and one end of the air exhaust movable cover arranged on the pot lid can automatically tilt upward, so that part steam is exhausted from the air exhaust opening; when air pressure in the pot decreases, the air exhaust movable cover can automatically close with the air exhaust opening. The utility model can not have the phenomenon that when air pressure in the pot rises to a certain degree, the pod lid is pushed up to cause holding food in the pot to overflow like a common pot lid does.

Description

The self-bleeding energy-saving cooker cover of a kind of supercharging

The utility model relates to a kind of kitchen utensils, when kettle temperature increases, and when air pressure increases to a certain degree, the supercharging automatic vent energy-saving cooker cover of closing voluntarily after can automatic vent.

Present known pot cover generally is the single integral body of non air exit hole, and what have opens an aperture on pot cover, and when the pot internal gas pressure increased to a certain degree, air pressure can cause food excessive through regular meeting the whole jack-up of pot cover; When air pressure increased, aperture still had little time exhaust to foraminate pot cover, equally can be, and in the process that kettle temperature increases gradually with the whole jack-up of pot cover, and when not needing exhaust, the part heat of still can draining of the aperture on the pot cover causes the waste of the energy; When the air pressure in the pot increases to a certain degree,, can cause food excessive equally because of the aperture on the pot cover still has little time exhaust with the whole jack-up of pot cover.

The purpose of this utility model provides the self-bleeding energy-saving cooker cover of a kind of supercharging, and when the air pressure in the pot did not acquire a certain degree, exhaust outlet on the pot cover and exhaust events lid were in closure state; When the pot internal gas pressure increases to a certain degree, exhaust events lid on the pot cover can up start automatically, discharges steam from exhaust outlet, the whole jack-up of pot cover can not caused the excessive and pollution article on every side of pot interior food, simultaneously pot interior hot gas can not lost in a large number, reach purpose of energy saving.

The purpose of this utility model is achieved in that exhaust outlet of increase above pot cover, an exhaust events lid bigger slightly than exhaust outlet is arranged on exhaust outlet, be fixed on the pot cover with the upper end that flexibly connects the exhaust events lid, exhaust events is covered can be up and down, coincide mutually with exhaust outlet again, making it to become one can closed fully pot cover when the pot internal gas pressure does not acquire a certain degree.When the air pressure in the pot acquired a certain degree, an end that is installed in the exhaust events lid above the exhaust outlet can up start automatically, from exhaust outlet discharge section steam pot internal gas pressure is descended after, the exhaust events lid can be automatically and the exhaust outlet closure.Can not make air pressure cause pot interior food excessive the whole jack-up of pot cover like this.

Below in conjunction with drawings and Examples the utility model is further specified: among the figure 1, exhaust outlet 2, exhaust events lid 3 flexibly connects 4, pot cover

In the drawings, a top increase exhaust outlet (1) of pot cover, bigger slightly than exhaust outlet (1) and match a with it exhaust events lid (2) is arranged on exhaust outlet (1), be fixed on the pot cover (4) with flexibly connecting (3) upper end exhaust events lid (2), make the exhaust events lid can be up and down, again the self-bleeding energy-saving cooker cover of supercharging that can coincide mutually with exhaust outlet.When the air pressure in the pot acquired a certain degree, an end of exhaust events lid (2) can up start automatically, and steam is discharged from exhaust outlet (1), made the pot cover (4) can be by the whole jack-up of air pressure.

Claims

1, the self-bleeding energy-saving cooker cover of a kind of supercharging, exhaust outlet of increase, flexible connection, exhaust events lid on pot cover, it is characterized in that: exhaust outlet of increase on pot cover, an exhaust events lid bigger slightly than exhaust outlet is arranged on exhaust outlet, be fixed on the pot cover with the upper end that flexibly connects the exhaust events lid, exhaust events is covered can be up and down, can coincide mutually with exhaust outlet again, just in time carries out and cover on exhaust outlet.

2, the self-bleeding energy-saving cooker cover of supercharging according to claim 1, it is characterized in that: exhaust outlet on the pot cover and exhaust events are covered and be in closure state when air pressure are low, temperature in pot raises, when air pressure increases, one end of exhaust events lid can up start automatically, reached the purpose of exhaust, after the exhaust, meeting of exhaust events lid and exhaust outlet auto-closing.
