Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

Energy concentrating discs 300 and cooktops 100 of some embodiments of the present invention are described below with reference to fig. 1-8.

The energy collecting disc is one of important parts in the kitchen range and has the function of being matched with a burner in the kitchen range for use so as to improve the heating efficiency of the burner. Particularly, when the household or commercial kitchen range equipment is used, fuel such as gas, coal gas, methane and the like is ignited and combusted through the combustor, the energy collecting disc arranged around the periphery of the combustor can guide and strengthen heat exchange between high-temperature flue gas and the bottom of a cooking utensil, heat dissipation of the high-temperature flue gas to the atmosphere is reduced, and meanwhile, the heated energy collecting disc can also radiate heat transfer to the bottom of a pot, so that the energy collecting disc can improve the heating efficiency of the kitchen range to a certain extent. When the combustor burns fuel, the combustor mixes the combustion with air, so that the mixture of the combustion and the air is mixed again to realize the combustion. Here, air that is first mixed with combustion is referred to as primary air, and air that is introduced again is referred to as secondary air. The introduction of secondary air enables sufficient combustion of the fuel. In the cookers of the related art, the secondary air required for fuel combustion is introduced and supplemented directly from the ambient air. This has the problem that the supply of secondary air from the environment is random and the amount of supply is not controlled. When the secondary air is supplied excessively, the overall thermal efficiency of the burner is low. When the supply of the secondary air is insufficient, the amount of harmful gas emissions from the burner is increased. Therefore, the technical scheme that the supply quantity of the secondary air can be reasonably controlled, meanwhile, the waste heat of the high-temperature disk surface is recovered by heating the heat conducting part through the secondary air, and the recovered heat is brought into a combustion area by the heated secondary air so as to improve the overall efficiency, so that the combustion efficiency of a cooker combustor is ensured, and the harmful gas emission quantity of the combustor is reduced is lacked in the related technology.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The present embodiment provides a concentrator disk 300 and a cooktop 100. The reason for adopting this embodiment is that the gas stove systems on the market at present all adopt the traditional atmospheric combustion mode, and the secondary air amount required by gas combustion is supplemented from the ambient air.

In addition, the main mode of the efficiency enhancement of the gas stove in the related technology is to adopt an energy-collecting disc technology, the energy-collecting disc guides and strengthens the heat exchange between the high-temperature flue gas and the pot bottom, the heat dissipation of the high-temperature flue gas to the atmosphere is reduced, and meanwhile, the heated energy-collecting disc conducts heat to the pot bottom in a radiation mode. The mode greatly improves the heat efficiency of the gas stove, but the efficiency improvement is close to the limit at present. And for a fully premixed gas range, high thermal efficiency and low emission can be obtained. However, the gas stove adopts a fully premixed combustion mode, which is easy to cause tempering, and burning explosion may occur under severe conditions. In addition, stable combustion, especially at low operating conditions, is a significant challenge for fully premixed gas burners. The full premix combustion of the open system also easily causes problems of blockage, blowing and suction, liquid seepage, low service life and the like. In order to ensure a reasonable degree of secondary air supply and improve the combustion efficiency of the hob 100, the present embodiment provides the following energy concentrating discs 300 and the hob 100.

The present embodiment provides a high efficiency semi-closed cooking appliance 100, which is specifically a gas range. The concentrator disk 300 of the cooktop 100 of the present embodiment introduces secondary air through a plenum assembly 340, such as a small fan. The air delivery assembly 340 precisely matches the secondary air intake through the opening of the valve 230 of the flame output member 210 in the burner 200, while allowing reasonable distribution of secondary air between the inner and outer ring flames via the semi-enclosed air flow passages 330 in the concentrator disk 300. Meanwhile, the secondary air in the air flow passage 330 may be preheated, and the present embodiment can reduce harmful emissions while improving the overall heat efficiency of the cooker 100.

In some embodiments of this embodiment, the energy collecting disc 300 of the burner 200 semi-closed system of the cooker 100 encloses and provides secondary air from the energy collecting disc 300, and the flow path of the secondary air is the central passage of the energy collecting disc 300 of the semi-closed system, namely: an air flow channel 330. The concentrator disk 300 of the present embodiment has a double-layered concentrator disk structure in which double-layered concentrator disk systems are connected by heat conductive members 360 such as fins, and secondary air flows therein while being preheated by hot flue gas in the combustion zone. The energy concentrating disk 300 with the double-layer energy concentrating disk structure further comprises a support part 370, which can provide a pan support function, pan support contacts, namely: the supporting portion 370 is disposed at the top of the energy collecting plate 300, and the heat absorbed by the supporting portion can be recovered by the secondary air, thereby improving the heat efficiency.

Since the secondary air of the present embodiment is supplied from the air supply unit 340, the air flow rate thereof can be accurately controlled. In addition, the secondary air control supply assembly 340 can be in signal communication with the valve 230 of the flame output section 210 of the burner 200 to ensure that the required amount of air can be accurately supplied at different valve 230 opening degrees. The secondary air enters the outer and inner ring flame regions via the first and

second disks

312, 314 disposed one above the other. Gas feed assembly 340 is located below a panel of cooktop 100.

Advantages of this embodiment include the following. Firstly, the air supply assembly 340 matches the opening degree of the valve 230 to accurately supply the secondary air, and can ensure that the equivalence ratio of fuel and air is in a reasonable range in the combustion process, thereby greatly reducing the heat absorbed by the heated redundant secondary air, ensuring that more heat is absorbed by the heated object, and greatly improving the heat efficiency. In addition, the arrangement of the inner and outer layers of energy collecting plates comprising the first plate body 312 and the second plate body 314 greatly reduces the loss of heat of the smoke. When the energy collecting discs of the single disc body are arranged, the heat of the energy collecting discs can still radiate heat outwards, and after the second disc body 314 such as the outer energy collecting disc is arranged, the energy loss of the part is greatly reduced. The air flow channels 330 in the energy collecting discs 300 can enable secondary air to enter a combustion area after absorbing heat of the energy collecting discs 300, and the energy efficiency is greatly improved by recovering the heat. In addition, this embodiment makes the secondary air passageway rationally distribute between inner ring fire and outer ring fire to guarantee that whole combustion zone can both fully burn, in order to reach the purpose that reduces pollutant discharge. The secondary air enters the combustion system after being preheated, insufficient combustion generated when cold air directly enters a combustion area is avoided, and therefore the purpose of low pollutant emission is further achieved.

To sum up, the utility model discloses beneficial effect does:

1. the embodiment can supply secondary air to the burner 200 through the energy collecting disc 300, and the supply amount of the secondary air of the cooker 100 adopting the energy collecting disc 300 of the embodiment is easy to control, so that the embodiment can fully ensure the combustion efficiency of the burner of the cooker and reduce the harmful gas emission amount of the burner.

2. The embodiment can reasonably distribute the secondary air supply amount of the inner ring flame and the outer ring flame, and avoid the problems of overhigh smoke emission, yellow flame, soft flame and the like caused by unreasonable or uncontrollable distribution of the secondary air supply amount of the inner ring flame and the outer ring flame.
