Abstract
The invention relates to a muffle device applied in an electric heating cooker, which comprises an electric heating cooker body. A gas outlet device of the electric heating cooker body is provided with a gas exhaust valve core. The gas exhaust valve core comprises orderly communicated valve core gas inlet, a valve core cavity body, and a valve core gas outlet. The section inside the valve core cavity body is larger than the sections of the valve core gas inlet and the valve core gas outlet; a plurality of muffle partition boards which divides the valve plug cavity body into a plurality of small cavity bodies are arranged in the valve core cavity body at intervals; each muffle partition board is provided with a plurality of vent holes; and the positions of the plurality of the vent holes of every two adjacent muffle partition board are arranged in interlaced mode. With the structure, gas is subjected to multiple mutations, and sound energy is greatly attenuated, thereby playing a role in reducing noise of exhausting gas.
Description
Technical field
The present invention relates to the electric heating cooker technical field, refer in particular to a kind of silencing means that is applied in the electric heating cooker.
Background technology
At present, various electric heating cookers have obtained general application, and some in the electric heating cooker have adopted high pressure to cook, and can quickly food be boiled, as electric pressure cooking saucepan etc.Adopt these voltage power heating cookers with food cooked after, need carry out release, existingly unload that laminated structure is made of straight-through relief tube and the weight valve on it, relief tube is communicated with pressure cooker inner high voltage gas and external pressure, and when lifting weight valve, relief tube directly is released to the high pressure gas in the pot in the external pressure, because high pressure gas directly sprays, the pulsation of air-flow is very big, the sound wave of very fast some frequency of generation of flow velocity, and the noise that these releases produce is ear-piercing especially, brings discomfort to the user.
Summary of the invention
Purpose of the present invention is exactly that provide at the deficiencies in the prior art part a kind of reduces exhaust noise, is applied in the silencing means in the electric heating cooker.
For achieving the above object, the present invention includes the electric heating cooker body, on the air-out apparatus of electric heating cooker body, be provided with exhaust plug, described exhaust plug includes successively spool air inlet, spool cavity and the spool gas outlet that is communicated with, and the cross section in the spool cavity is respectively greater than the cross section of spool air inlet and spool gas outlet; Some sound gobos that the spool cavity are divided into several little cavitys are located at interval in the spool cavity, offer several passages on the every sound gobo, and the position of several passages on two adjacent in twos sound gobos is dislocation and offers.
After adopting said structure, when blast pipe entered exhaust plug, because the sectional area from the spool air inlet to the spool cavity increases, air-flow was expanded gas with high speed, and flow velocity reduces, and powerful microseismic noise is decayed; When air-flow continues to flow through each loculus body, because stopping of sound gobo, air-flow can only be from throttling on the passage on the sound gobo, so air-flow is compressed suddenly, be divided into many threads, because the passage mutual dislocation on the two adjacent sound gobos, air-flow can't be directly passage from the two adjacent sound gobos pass, the little cavity of air-flow between two adjacent sound gobos obtains expansion; So repeatedly sudden change, the big high attenuation of acoustic energy quilt, thus play the effect that reduces exhaust noise.
Description of drawings
Fig. 1 is the structural representation of exhaust plug of the present invention.
Fig. 2 is the structural representation of sound gobo of the present invention.
The specific embodiment
Show as Fig. 1-2, the present invention includes the electric heating cooker body, on the air-out apparatus of electric heating cooker body, be provided with exhaust plug 10, described exhaust plug 10 includes successively spool air inlet 11, spool cavity 12 and the spool gas outlet 13 that is communicated with, and the cross section in the spool cavity 12 is respectively greater than the cross section of spool air inlet 11 and spool gas outlet 13; The some sound gobos 14 that spool cavity 12 are divided into several little cavitys are located in spool cavity 12 at interval, offer several passages 141 on the every sound gobo 14, the position of several passages 141 on two adjacent in twos sound gobos 14 is dislocation and offers.Described electric heating cooker is an electric pressure cooking saucepan.Described exhaust plug 12 is located in the middle of the pipeline in the air-out apparatus of electric heating cooker body.Described exhaust plug 10 is located on the air intake gas port or air-out gas port in the air-out apparatus of electric heating cooker body.Described some sound gobos 14 are at least more than one or one.Described exhaust plug 10 be located on the pot cover of electric heating cooker body or the pot of electric heating cooker body on one's body.
Embodiment as shown in Figure 1, sound gobo 14 is three, exhaust plug 10 is formed by four mutual clampings of part, and at two adjacent sound gobos 14 of access sections grafting, this structure easy accessibility is convenient to produce in batches.
During use, adopt electric heating cooker with food cooked after, need carry out release, gases at high pressure in the pot are with at a high speed when blast pipe enters exhaust plug 10, because the sectional area from spool air inlet 11 to spool cavity 12 increases, air-flow is expanded, and flow velocity reduces, and powerful microseismic noise is decayed; When air-flow continues to flow through each loculus body, because stopping of sound gobo 14, air-flow can only be from throttling on the passage on the sound gobo 14 141, so air-flow is compressed suddenly, be divided into many threads, because passage 141 mutual dislocation on the two adjacent sound gobos 14, air-flow can't be directly passage 141 from the two adjacent sound gobos 14 pass, the little cavity of air-flow between two adjacent sound gobos 141 obtains expanding, so repeatedly sudden change, air-flow 13 discharges from the spool gas outlet at last, the big high attenuation of acoustic energy quilt, thus play the effect that reduces exhaust noise.
It is staggered that the arranging of the passage 141 of two adjacent sound gobos 14 among the present invention can be carried out as required; The user also can adopt sound gobo 14 that spool cavity 12 is partitioned into the little cavity of setting number according to actual needs, so just can repeatedly decay to the noise of air-flow, makes reduction exhaust noise effect reach best.
