Abstract
The utility model relates to a silencing device applied in the electrical heating cooker, including an electrical heating cooker body. A vent valve core is arranged on the air-out apparatus of the electrical heating cooker body. The vent valve core includes a valve core air inlet, a valve core chamber and a valve core outlet which are communicated in turn. The section of the valve core chamber is respectively larger than that of the air inlet and the air outlet of the valve core. A plurality of silencing partition plates which divide the valve core chamber into a plurality of small chambers are arranged in the valve core chamber at internals. A plurality of vents are arranged on each silencing partition plate. Several vents are arranged in stagger mode on two adjacent silencing partition plates. The silencing device can greatly decrease the sound energy by multi gas change so as to reduce the exhaust noise.
Description
Technical field
The utility model relates to the electric heating cooker technical field, refers 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
The purpose of this utility model 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 utility model 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 utility model.
Fig. 2 is the structural representation of sound gobo of the present utility model.
The specific embodiment
Show as Fig. 1-2, the utility model 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 in the utility model 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.
