Abstract

A anti-overflow pot lid for electrical cooker, comprising a lid [1], which is characterized in that an aeration overflow hole [2] is provided on the lid [1], a hole cover [3] is arranged on the aeration overflow hole [2]. A side edge of the hole cover [3] is hinged to the lid [1]. The aeration overflow hole [2] is a round hole with diameter range 10%-30% of that of the entire lid [1]. While in use, the air pressure in the pot rises up, the hole cover in the aeration overflow hole is slightly jacked up by the steam, few of rice soup flows to the surface of the lid through the aeration overflow hole and is collected in the blocking groove in the jar which effectively protects the rice soup against flowing out the jar.

Description

The anti-overflow electric cooker lid

Technical field

The utility model relates to a kind of electric cooker, is specifically related to a kind of electric cooker lid that prevents that thin rice gruel from overflowing.

Background technology

Electric cooker is a kind of modal electrical equipment of cooking, cooking congee.Existing commercially available electric cooker does not all have the anti-overflow function, and promptly when meal (or congee) when boiling, thin rice gruel can overflow outside the pot, pollutes the outer pan body surface, even flows on the desktop through the pot surface, the pollution desktop.Therefore after electric cooker was used, except that pot cover, inner pan body will clean, the pot body surface of its outer pan body also needed frequent wiping, and as untimely wiped clean, thin rice gruel will be formed scar, is difficult to wipe, even can corrodes a pot body, seems unhygienic and not attractive in appearance.Even more serious is: if thin rice gruel flows to the power switch place of outer pan body, also can cause short circuit.

Analysis is got up, the main cause that produces spillover is: the pot cover of existing electric cooker is whole airtight lid, or just have a slight miniature passage thereon, after meal, congee are boiled, steam can be once down with pot cover jack-up, thin rice gruel overflows from the pot cover edge, though existing electric cooker inner pan body all is provided with a circle retaining groove on uncovered, but how many effects this retaining groove does not play to anti-overflow, and thin rice gruel still can be crossed retaining groove and overflow on one's body the outer pot pot.

Summary of the invention

The utility model purpose is to carry out architecture advances on existing electric cooker lid, a kind of electric cooker lid with anti-overflow function is provided, flows to the hidden danger that the power switch place may cause short circuit because of thin rice gruel to avoid thin rice gruel overflows outside the pot when using electric cooker to cook trouble and elimination.

For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-overflow electric cooker lid, comprise a lid, and offer the ventilation overfolw hole on the described lid, this ventilation overfolw hole loam cake has port lid, and a side of port lid is hinged on the lid.

Related content in the technique scheme is explained as follows:

1, in the such scheme, described ventilation overfolw hole is a through hole, and its effect is the ventilation release and converges and overflow thin rice gruel that its shape is not limit, and can be circular hole, slotted hole or square hole; As for the size of ventilation overfolw hole, when it was circular hole, its diameter was the 10%～30% preferable of whole lid diameter, and the best is about 20%; As for the position that is provided with of ventilation overfolw hole, be to be arranged on the lid of pot cover, particular location is not limit, and can be provided with near the outer rim place of pot cover, can be located at the center of pot cover yet, and is on effect, preferable near the outer rim place of pot cover.

2, in the such scheme, described port lid is hinged with a side and the lid of nearly lid outer rim, constitutes the flip structure that turns up with this.Like this when thin rice gruel from the ventilation overfolw hole when overflowing, be to branch in the retaining groove of inner pan body through the both sides on the hinged limit of port lid, shunting back anti-overflow effect is better, can not be spilled on one's body the outer pot pot because of flow is excessive.

3, in the such scheme, corresponding aperture is covered with groove on the described lid, and port lid is embedded in this groove, makes profile more attractive in appearance with this, more compact structure.

4, in the such scheme, the quantity of described ventilation overfolw hole can be one, also can be two, three etc., in general is provided with one and gets final product.

The utility model operation principle is: shown in accompanying drawing 1 and accompanying drawing 2, the utility model is used for electric cooker, when the meal in the pot is boiled, the pot internal gas pressure rises, the port lid 3 that steam will be ventilated on the overfolw hole 2 backs down release slightly, a spot of thin rice gruel flow to lid 1 surface from ventilation overfolw hole 2, these thin rice gruels are left some and also can converge in the retaining groove of inner pan body by very fast evaporation; When pot inner pressure reduced, port lid 3 covered ventilation overfolw hole 2 because of gravity reduction, played the effect that prevents heat leakage and retaining dust.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because special construction of the present utility model can prevent effectively that thin rice gruel from overflowing outside the pot, fine through practical effect.

2, the utility model is simple in structure, and is easy to make, with low cost, and is easy to clean.

3, because port lid of the present utility model is a side and a lid with nearly lid outer rim is hinged, it is the flip structure of outwards turning on one's side, like this when thin rice gruel from the ventilation overfolw hole when overflowing, be divided into two-way, this two-way flow in the retaining groove of inner pan body through the both sides on the hinged limit of port lid respectively, shunting back anti-overflow better effects if can not be spilled on one's body the outer pot pot because of the thin rice gruel flow is excessive.

Description of drawings

Accompanying drawing 1 is the utility model structural representation one, the normal shape of expression pot cover among the figure;

Accompanying drawing 2 is the utility model structural representation two, the state that port lid was backed down slightly by steam when expression was used among the figure.

In the above accompanying drawing: 1, lid; 2, ventilation overfolw hole; 3, port lid; 4, handle; 5, groove.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment: shown in accompanying drawing 1, accompanying drawing 2, a kind of anti-overflow electric cooker lid, form by a lid 1 and leader 4, offer the ventilation overfolw hole 2 of a circle on this lid 1, these ventilation overfolw hole 2 loam cakes have port lid 3, port lid 3 is hinged with a side and the lid 1 of nearly lid 1 outer rim, constitutes the flip structure that turns up with this.The diameter of described ventilation overfolw hole 2 is about 20% of whole lid 1 diameter; Corresponding port lid 3 is provided with groove 5 on the lid 1, and port lid 3 is embedded in this groove 5.
