Abstract

The utility model is composed of a cover body and handles arranged on the cover body. The center of the cover body is in the shape of the circular plate with low center and high periphery, and the concave part of the cover body is provided with a back flow hole. The upper edge of a pan body matched with the pan cover is made into a deeper edge form. When the liquid inside the pan boils, overflow foams are blocked by the edge of the pan body and can only flow to the center of the cover body along the inclined pan cover. After the foams are cooled and changed into liquid, the foams can overcome vapor pressure inside the pan under gravitational effect and flow back to the inside of the pan via the back flow hole. The pan cover can prevent the boiling liquid inside the pan overflowing outside the pan and avoid the condition that the flame is quenched and the range is dirtied.

Description

The formula of backflowing pot cover

The utility model relates to a kind of pot cover, belongs to the cooker field.

Common pot cover is made of circular lid and dress handle thereon, and cooking congee with ordinary pan is with big fire poach to be opened earlier, uses little fire again instead and endures.It is other unmanned and cause pot interior liquid and overflow outside the pot that Chang Yinshui drives the back stove therebetween, as if can not in time discovering, might put flame after liquid overflows out by water, and initiation coal gas releases accident.During with common pan boiling milk, even stove is other the people arranged, also regular meeting is because of the excessive speed of the milk kitchen range of making dirty too soon.

In view of above-mentioned, the purpose of this utility model is exactly that a kind of pot interior liquid of avoiding of design overflows the outer formula of the backflowing pot cover of pot.

For achieving the above object, the utility model is by the following technical solutions:

A kind of formula pot cover that backflows is made of lid and thereon handle of dress, it is characterized in that: it is low, high discoid all around that lid is the center, and the hole of backflowing is offered at lid indentation position.

With this pot cover match the pot body the upper edge make darker enclosing along shape, when in the pot during liquid boiling, the foam that overflows is subjected to pot body and encloses stopping of edge, can only flow to the lid center along interior oblique pot cover, after foam is cooled to liquid, can under the gravity effect, overcome steam pressure in the pot by in the orifice flow twice-cooked stir-frying of backflowing.Use this pot cover can prevent that the liquid of boiling in the pot from overflowing outside the pot, the situation of avoiding putting flame out by water or making kitchen range dirty takes place.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the pot body schematic diagram that matches with the utility model;

Fig. 3 is another embodiment of the present utility model.

Pot cover shown in Figure 1 is made of with the handle 1 that is contained on the lid 5 the bigger lid 5 of weight, it is low, high discoid all around that lid 5 is the center, the hole 6 of backflowing is offered at the indentation position, center of lid 5, the upper surface centre of lid 5 connects support 4, the upper end level of support 4 connects and is used for preventing that pot inner vapor hinders the gas block panel 2 of hand, and button shape handle 1 is installed on the gas block panel 2.

Fig. 2 is the pot body that matches with the utility model, and the darker edge of enclosing is made in its upper edge.The utility model pot cover is covered after on this pot body, pot cover will crouch be shortlisted for along in.When in the pot during liquid boiling, the foam that overflows is subjected to pot body and encloses stopping of edge, can only be along upper surface oblique in the lid 5 to the lid center flow, accumulate in the center pocket of lid 5 through the gap 3 of support 4, after foam was cooled to liquid, meeting overcome the steam pressure in the pot and flow back in the pot by the hole 6 of backflowing under the gravity effect.In order to accelerate the speed of backflowing, also can on lid 5, set out pore 7, venthole 7 can flush with lid 5, also can resemble shown in Figure 3ly to be higher than lid 5, in order to avoid flooded by hydrops.

Backflow the hole when being located at the center of lid 5, handle also can adopt the structure of bottom sides perforate, after it is contained in the lid center, the side opening of handle just is communicated with the hole of backflowing, lid center, liquid on the lid can flow into the hole of backflowing, lid center through the side opening of handle, so just can save gas block panel and support.

The hole of backflowing also can not be located at the center of lid, but establishes annular groove in the centre of lid, establishes the hole of backflowing again in annular groove, and handle is contained in the lid center, and this structure can be saved gas block panel and support.

Support if handle is made bridge shape, then can be saved in backflow at the center of establishing on lid hole or establish under the situation of annular groove.

In addition, also can resemble shown in Figure 3ly, establish hydrops hole 8 in the centre of lid, establish the hole of backflowing in the hole, so that admit more hydrops and accelerate the speed of backflowing, 1 on handle is made rod and is contained on the lid the relatively position at center, so just need not establish gas block panel and support.

In fact, no matter what shape handle gets, as long as be contained in the position of being partial to the center on the lid, just can save gas block panel and support.

In sum, the utility model pot cover can have following several structure:

Lid be the center low, all around high discoid-its on can set out pore; Annular groove can be established in the centre; Pit can be established in the centre.

2. backflow hole-can be located at the center of lid; Can be located in the annular groove.

3. handle is button shape, bridge shape or rod-button shape handle and can be contained in the lid center by support; Button shape handle also can leave side opening and directly be contained in the lid center; Bridge shape handle directly is contained in the lid center; The handle of rod or other shape is contained in the position of being partial to the center on the lid.
