Thus, the outside air can enter the cavity of the annular body through each air inlet channel to provide sufficient air for the combustion of the fuel gas in the burner. And because the air inlet channel is arranged in the energy collecting cavity, the heat in the energy collecting cavity can heat the air in the air inlet channel so as to improve the temperature of the air entering the cavity, thereby improving the combustion efficiency.
According to the utility model, the air blowing device can be used for inputting the external air into the air inlet channel, and the air blowing device can be not additionally arranged, so that the cavity is negative pressure due to the fact that the air is consumed in the combustion process of the fuel gas in the burner, and the external air can be sucked into the cavity through the air inlet channel.
Preferably, the air inlet at the outer end of the air inlet channel is in a horn shape with gradually increased diameters from inside to outside. Thereby facilitating the entry of ambient air into the intake passage. And the horn-shaped structure can accelerate the airflow entering the air inlet channel, so that more external air is injected.
In order to further increase the air supply amount, it is preferable that the flow area on the cross section of the air intake passage is gradually reduced along the flow direction of the air flow from the air intake port to the air output port. Therefore, the airflow flowing from the air inlet to the air outlet can be further accelerated, and more external air can be ejected.
Preferably, the air outlet at the inner end of the air inlet channel is positioned above the air inlet at the outer end of the air inlet channel.
In order to reduce the flow resistance of the air flow, it is preferable that the intake passage has a longitudinal section in the shape of a wing.
In each of the above embodiments, preferably, the air intake passage is provided at a bottom of the energy collecting chamber.
Preferably, the annular body has an annular top wall, the inner annular wall extending downward from an inner edge of the annular top wall, an outer annular wall extending downward from an outer edge of the annular top wall, and an annular bottom wall connecting the inner annular wall and the outer annular wall, and the annular top wall, the inner annular wall, the outer annular wall, and the annular bottom wall together form the energy collecting cavity;
the air inlet channel is disposed adjacent to the annular bottom wall of the annular body.
Preferably, the air inlet at the outer end of the air inlet channel faces downwards and penetrates through the annular bottom wall of the annular body.
Further, the air inlet at the outer end of the air inlet channel is inclined outwards from top to bottom.
Preferably, the inner edge of the annular top wall is located below the outer edge.
The utility model solves the second technical problem by adopting the technical proposal that: the pot support with the energy gathering ring is characterized in that: the device further comprises at least three vertically arranged supporting legs, the energy collecting rings are arranged at intervals along the circumferential direction, the lower parts of the supporting legs are positioned below the energy collecting rings, and a secondary air channel which is communicated with the outside and the cavity is formed between the lower parts of two adjacent supporting legs and the energy collecting rings. So that part of the outside air can enter the inner periphery of the energy collecting ring through the secondary air channel.
The technical scheme adopted by the utility model for solving the third technical problem is as follows: the combustion assembly with the pot support is characterized by further comprising a burner which is arranged in the cavity of the annular body.
The combustion assembly is used for a kitchen range.
Compared with the prior art, the utility model has the advantages that: through the air inlet channels which are arranged in the energy gathering cavity along the circumferential direction at intervals and extend radially, the air inlets at the outer ends of the air inlet channels are communicated with the outside, the air outlets at the inner ends of the air inlet channels penetrate through the inner annular wall of the corresponding energy gathering cavity and are communicated with the cavity, so that the outside air can enter the cavity of the annular body through the air inlet channels, and sufficient air is provided for gas combustion in the combustor. And because the air inlet channel is arranged in the energy collecting cavity, the heat in the energy collecting cavity can heat the air in the air inlet channel so as to improve the temperature of the air entering the cavity, thereby improving the combustion efficiency.
