Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figure 1, Figure 2, Figure 3 shows, the cumulative component of a kind of gas-cooker, including the first cumulative circle 1, the second cumulative circle 2 and
Pan bracket 3, pan bracket 3 is arranged between the first cumulative circle 1 and the second cumulative circle 2.
As shown in figure 3, the first cumulative circle 1 is annular, the level height of outer shroud is higher than the level height of internal ring, i.e. inner side
Edge is less than outer side edges edge, and radial dimension is from top to bottom gradually reduced, and inner side edge is along the perisporium for extending downwardly formed below, structure
Into the bottom 12 of the first cumulative circle 1, on the first cumulative circle 1, outside bottom 12 the first cumulative circle internal perisporium 11 is formed with.
As shown in figure 3, pan bracket 3 include annular base 31 and be located in the circumference of base 31 at least three circumferentially between
Every the pot leg 32 of arrangement.The top of pot leg 32 has inclined-plane 33, and inclined-plane 33 can more fit with the bottom of a pan.Base 31 is placed in
In the bottom 12 of the lower end oral area of one cumulative circle 1, pot leg 32 is located on the first cumulative circle internal perisporium 11, and the bottom of leg 32 is shaped to
The arc matched with the first cumulative circle internal perisporium 11.
As shown in Fig. 1, Fig. 3, Fig. 4, the second cumulative circle 2 is also annular, and the second cumulative circle 2 is arranged on the first cumulative circle 1
On, the level height of the outer shroud of the second cumulative circle 1 is higher than the level height of internal ring, i.e., inner side edge is along less than outer side edges edge, footpath
From top to bottom it is gradually reduced to size.The outer side edges of the second cumulative circle 2 along the distance with kitchen range top surface (i.e. the second cumulative circle 2
Highly), the inner side edge of the second cumulative circle 2 is along being certain value (standard value) with the distance between burner, therefore the second cumulative circle 2
The angle beta of line and horizontal direction between of interior survey edge and outer side edges be 40～60 °, thus both can ensure that auxiliary air
Certain stroke (heat exchange area), can to greatest extent reduce the resistance of auxiliary air again.
Internal perisporium 26 and periphery wall 27 are formed with second cumulative circle 2, there are a plurality of concentric ring recesses on internal perisporium 26
22, groove 22 can increase radiation heat transfer ascent of the second cumulative circle to the bottom of a pan, play a part of Enhanced Radiation Reduced Blast heat exchange.Periphery
There is a plurality of concentric annular projection 23, raised 23 can increase the surface area of heat exchange surface on wall 27.Due to the second cumulative circle 2
Bottom temp is relatively low, thus by a plurality of raised 23 be arranged to from outside to inside, width gradually increase, i.e., from high to low width gradually increases
Greatly so that the heat exchange area of temperature lower is larger, heat exchange efficiency is improved.
Offer with the corresponding position of pot leg 32 what size and pot leg 32 matched in the circumference of the second cumulative circle 2
Opening 21, when the lid of the second cumulative circle 2 is placed on pan bracket 3, leg 32 is by opening 21, and the level height at the top of pot leg 32 is high
In the level height of the upper end of the second cumulative circle 2.
The distance piece of at least three circumferentially spaced arrangements is provided between the first cumulative circle 1 and the second cumulative circle 2, by
This causes have gap d between the first cumulative circle 1 and the second cumulative circle 2, using between the second cumulative circle 2 and the first cumulative circle 1
The auxiliary air that formed of gap d plus the passage of heat, reduce heat and scatter and disappear, improve the thermal efficiency.
In the present embodiment, distance piece is the support feet 28 for being fixed on the lower surface of the second cumulative circle 2, the bottom of support feet 28
It is supported on the inner side of base 31.Alternatively, distance piece is the support feet 28 of the upper surface for being fixed on the first cumulative circle 1.
Two panels fin 24 is interval with periphery wall 27 between two neighboring opening 21, fin 24 is raised with concentric annular
23 intersect vertically, and can increase the contact area of air and the cover body of the second cumulative circle 2, increase heat exchange efficiency to improve auxiliary air temperature
Degree.Additionally, fin 24 also can be used as above-mentioned distance piece.
Due to flue gas from the bottom of a pan lower section, near exit flow out when, seat auxiliary air can be rolled up and heat is lost, therefore, the
Along the flue gas flow deflector 25 for extending radially outwardly is formed with, flue gas flow deflector 25 can be carried out the outer side edges of two cumulative circles 2 to flue gas
Water conservancy diversion so that flue gas is just being contacted after flue gas flow deflector 25 with auxiliary air, and the temperature of flue gas, velocity of liquid assets are reduced,
Can effectively prevent flue gas from losing heat because volume inhales auxiliary air near exit.
As shown in figure 5, the gap between the second cumulative circle 2 and the first cumulative circle 1 is d, it is preferred that gap d is on vertically
For 2mm～5mm.Arrange below the second cumulative circle 2 first cumulative circle 1 the second cumulative circle 2 can be greatly decreased to ambient air and
The lost temperature of table top, the gap d between the second cumulative circle 2 and the first cumulative circle 1 defines auxiliary air plus the passage of heat, and this leads to
Road improves estimated secondary air temperature using the waste heat of the second cumulative circle 2 and the dispersed heat of pan bracket 3 and the first cumulative circle 1,
Serve the effect for improving ignition temperature and lifting the thermal efficiency.
