Abstract

The utility model discloses a spherule micro-pressure steam valve of an electric rice cooker, which is arranged on a cover body of the electronic rice cooker. The utility model is characterized in that the utility model is composed of a valve cover (1) and a valve body (3) mutually and movably connected, wherein an air inlet passage (32) connected with an inner cavity of the electronic rice cooker is arranged in the valve body (3), a buckle (31) with an end part projected inward is extendedly arranged at the top part, a spherule (2) is arranged in the cavity enclosed by the buckle (31), and the diameter of the spherule is greater than the diameter of the air inlet passage (32) and the diameter of top opening of the buckle (31). The utility model has the advantages that the rice water overflowing and gathering in the valve to form a jam is prevented, meanwhile the micro-pressure can be produced, the steam valve is easy to disassemble and wash after used, keeping the cover of the electronic rice cooker clean.

Description

Electric cooker bead minute-pressure steam valve

Technical field

The utility model relates to a kind of steam valve that is used on the electric cooker pot cover, belongs to the improvement technology of the used steam valve of electric cooker.

Background technology

Present commercially available electric cooker, as shown in Figure 4, its steam valve that is installed in the electric cooker pot cover is generally non-dismountable formula, and valve gap is fixed on pot and covers on 5, and non-dismountable, valve body 8 spiral-locks are fixed on inner cap 7 and the sealing ring 6, and valve body 8 is provided with air admission hole 9.When cooking, the thin rice gruel steam in the pot enters valve body 8 from air admission hole 9, is broken into thin rice gruel during thin rice gruel bubble process air admission hole 9, is back to the interior pot that food is housed, and plays the anti-overflow effect.But the electric cooker steam valve of this structure, because when the thin rice gruel bubble enters in the valve body 8 from air admission hole 9, respond well to the broken bubble of bigger bubble, but little broken bubble can the direct admission valve body in, little broken bubble is assembled more for a long time in valve body, will overflow by venthole 10, not reach good anti-overflow effect.And non-removable steam valve easy cleaning not, the thin rice gruel vestiges are easy to accumulate in the valve, form to stop up, and do not have the effect of anti-overflow.

Summary of the invention

The purpose of this utility model is to provide a kind of good anti-overflow effect that has, the readily removable easy cleaning of steam valve, and can realize the electric cooker bead minute-pressure steam valve of minute-pressure power effect.

Technical solution of the present utility model is: a kind of electric cooker bead minute-pressure steam valve, be located on the lid of electric cooker, it is made up of the valve gap and the valve body of mutual flexible connection, wherein in valve body, be provided with the inlet channel that communicates with the electric cooker inner chamber, its top extend be provided with the end inwardly outstanding grab button, in grabbing the cavity that surrounds of button, be provided with bead, and this little bulb diameter is greater than the inlet channel diameter with grab and detain the top opening diameter.

The movable setting can be easy to open cleaning, in the use between the valve gap of steam valve and the valve body, thin rice gruel steam enters by inlet channel, bead is positioned at the inlet channel top, blocks passage, can be with bead jack-up when steam pressure is enough, form gap between bead and the inlet channel top this moment, bubble gap thus passes through, and less because of the gap, the bubble of process all can break, broken bubble effect is obvious, effectively prevents to overflow; Grabbing button can constrains ball be gone out by steam, can prevent that also bead from rolling out when cleaning, and has constant weight because of bead simultaneously, only just can also be made like this and produce certain minute-pressure effect in pot by jack-up when steam pressure is enough.

As a kind of prioritization scheme, described valve body bottom is provided with the return port that communicates with the electric cooker inner chamber, this return port is provided with unidirectional recirculation control device, can advance return port and be back in pot accumulating in thin rice gruel in the valve body like this, unidirectional recirculation control device can prevent that steam from entering in the valve body by return port, guarantees broken bubble effect.

Described unidirectional recirculation control device is to be located at the outer elastic rubber fitting in return port bottom, unidirectional backflow control structure like this is simple, is quick on the draw, and thin rice gruel is less or when not having thin rice gruel in valve body, pot internal gas pressure can withstand on rubber cushion outside the return port bottom, guarantees that steam only enters by inlet channel.

Be provided with the catch that in described valve body, extends on the described lid, can controlling the steam flow that enters in the valve body, and can make the easier condensation of thin rice gruel steam.

The utility model has the advantages that, in the process that electric cooker is cooked, can prevent that thin rice gruel from overflowing the also residual interior formation obstruction of valve that accumulates in, and can make a pot interior generation minute-pressure simultaneously, the readily removable easy cleaning steam valve in use back, the sanitation and hygiene that maintenance is stewed and covered.

The specific embodiment

Embodiment:

Referring to accompanying drawing 1 to 3, a kind of electric cooker bead minute-pressure steam valve is located on the lid of electric cooker, and it is made up of the valve gap 1 and the valve body 3 of mutual flexible connection, is being provided with the catch 11 that extends in valve body 3 on the lid 1; In valve body 3, be provided with the circular inlet channel 32 that communicates with the electric cooker inner chamber, its bottom is provided with air inlet 34, its top extension is provided with inwardly outstanding the grabbing in six ends and detains 31, in grabbing button 31 cavitys that surround, be provided with bead 2, and these bead 2 diameters are detained 31 top opening diameters greater than inlet channel 32 diameters with grabbing.

The return port 33 that communicates with the electric cooker inner chamber that valve body 3 bottoms are provided with centre bore 35 and are provided with around centre bore 35, be provided with unidirectional recirculation control device outside the return port 33, this unidirectional recirculation control device is the elastic rubber fitting 4 that is located at outside return port 33 bottoms, this rubber cushion 4 is made up of round and elastic film 42 and the elasticity back-off 41 that is located at the middle part, but elasticity back-off 41 snap fit are on centre bore 35, make rubber cushion 4 center fixation on valve body 3, elastic film 42 overlays on outside the return port 33, thin rice gruel is less or when not having thin rice gruel in valve body 3, pot internal gas pressure can withstand on elastic film 42 outside return port 33 bottoms, guarantees that steam only enters by inlet channel 32.

Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
