Abstract

The utility model discloses a metal cellular energy-collecting cover of a gas stove. The metal cellular energy-collecting cover comprises a housing body, and a cellular inner core which is arranged inside the housing body, wherein fire outlets which are straight up and down are densely distributed in the entire inner core. The metal cellular energy-collecting cover can be directly assembled above an existing burner; a gas can completely burn; emission of NOX and CO is reduced; loss of heat can be effectively reduced; the energy collecting effect is achieved; the utilization rate of heat is increased.

Description

The Metal Cellular Gas-tight energy gathering cap of gas-cooker

Technical field

The utility model relates to gas-cooker, is specially the Metal Cellular Gas-tight energy gathering cap of gas-cooker.

Background technology

At present, general gas-cooker does not all arrange energy gathering cap structure, and heat in the combustion gas Er Dui the bottom of a pan of directly burning on the venthole of burner, and flame volume is large and disperse, and easily occurs the insufficient phenomenon of burning, produces a large amount of NOX and CO discharge.

In addition, because of the flame envelope portion temperature of flame the highest, for obtaining best heating-up temperature, pot is generally placed on flame top by the support segment distance of being separated by, such structure setting not only causes the heating surface area in the bottom of a pan little, can cause again heat to be lost in a large number in air, further reduced the utilization rate of fuel gas buring heat simultaneously.

Utility model content

For the problems referred to above, the utility model has designed a kind of Metal Cellular Gas-tight energy gathering cap of gas-cooker, it can directly be provided in existing burner top, can not only make combustion gas completing combustion, reduce NOX and CO discharge, and can effectively reduce scattering and disappearing of heat, and realize cumulative effect, promote the utilization rate of heat.

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

A Metal Cellular Gas-tight energy gathering cap, it is characterized in that: comprise shell body and be arranged on the honeycomb fashion inner core in shell body, on whole inner core, gather and be provided with straight-through up and down fire output hole.

Further, the density of above-mentioned fire output hole is for being no less than per square inch 200 orders.

Further, above-mentioned inner core is arranged by space a plurality of wave plates and plain film are reeled and are formed in concentric circles mode.

Further, the upper surface of above-mentioned inner core is arranged to planar structure.

Further, the upper surface of above-mentioned inner core is arranged to the peripheral high concave configuration of center bottom.

Further, above-mentioned inner core bottom is provided with flue gas sharing net, and all the density of subnetting is for being no less than per square inch 1000 orders.

Further, above-mentioned inner core center hollow forms burner installing hole.

Further, above-mentioned shell body, inner core and equal subnetting all adopt refractory metal material to make.

The energy gathering cap of the utility model design, the burner top that it can directly be provided in existing gas-cooker is directly shelved on pot on the inner core of energy gathering cap simultaneously.

In use, combustion gas enters energy gathering cap inner core by the equal subnetting of bottom, by thousands of fire output holes of core upper surface, draws flammule, not only effectively increase burning area, promote the thermal efficiency, and can make fuel gas buring more abundant, reduce the discharge capacity of NOx, CO.

In addition, the upper surface of being close to energy gathering cap inner core because of the bottom of a pan heats, for direct contact thermaltransmission mode, not only heat transference efficiency is high, and as much as possible reduced fuel gas buring heat and scattered and disappeared to airborne, realize cumulative effect, can further promote the utilization rate of fuel gas buring heat.

The longitudinal cross-section schematic diagram of Fig. 3, the utility model inner core the second embodiment.

The specific embodiment

As shown in Figure 1, a kind of Metal Cellular Gas-tight energy gathering cap of gas-cooker, comprise shell body 1 and be arranged on the honeycomb fashion inner core 2 in shell body 1, on whole inner core 2, gather and be provided with straight-through up and down fire output hole 211, for obtaining large-area flammule, fire output hole 211 density on described inner core 2 are for being no less than per square inch 200 orders.

In the present embodiment, above whole inner core 2 is arranged by space a plurality of wave plates 21 and plain film 22 are reeled and are formed in concentric circles mode.

In practice, the upper surface of inner core 2 can be arranged to planar structure as required, with what adapt to pan, be close to heating needs, its structure as shown in Figure 2, equally also the upper surface of inner core 2 can be arranged to the peripheral high concave configuration of center bottom, with what adapt to circular bottom pot, be close to heating needs, its structure as shown in Figure 3.

At this, for making the combustion gas can be completely and enter into uniformly each fire output hole 211 of inner core 2, described inner core 2 bottoms be provided with flue gas sharing net 3, and all the density of subnetting 3 is for being no less than per square inch 1000 orders.

In addition,, for meeting actual needs, described inner core 2 center hollow form burner installing hole 212.

The utility model form the shell body 1, inner core 2 of energy gathering cap and all subnetting 3 all adopt refractory metal material to make, it can directly be provided in the burner top of existing gas-cooker, pot is directly shelved on the inner core 2 of energy gathering cap and is heated simultaneously.

In use, combustion gas enters energy gathering cap inner core 2 by the equal subnetting 3 of bottom, by thousands of fire output holes 211 of inner core 2 upper surfaces, draws flammule, not only effectively increase burning area, promote the thermal efficiency, and can make fuel gas buring more abundant, reduce the discharge capacity of NOx, CO.

In addition the upper surface that energy gathering cap inner core 2 is close in the ，Yin the bottom of a pan heats, and is direct contact thermaltransmission mode, not only heat transference efficiency is high, and as much as possible reduced fuel gas buring heat and scattered and disappeared in air, realized cumulative effect, can further promote the utilization rate of fuel gas buring heat.

The above, it is only better embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation know-why of the present utility model, to any simple modification made for any of the above embodiments, equivalent variations or modification, still belongs in the scope of technical solutions of the utility model.
