Description

Gas cooker pan support for flue gas and air heat exchange

【Technical field】

The invention relates to a pot support for a gas stove.

【Background technique】

At present, the commonly used gas cooker pot support structure is to set several supporting feet on the annular steel ring to hold the bottom of the pot firmly. This kind of gas cooker pot support is only used to support the pot. After the heat exchange is completed, a large amount of waste heat will be dissipated into the air, resulting in a large amount of heat energy loss and waste.

【Content of invention】

In order to solve the deficiencies in the prior art and provide a pot support that effectively utilizes the heat of flue gas after combustion to improve thermal efficiency, the technical solution adopted in the present invention is:

A gas cooker pan support for heat exchange between flue gas and air, characterized in that it includes an annular flow guide plate, and a plurality of heat exchange fins arranged vertically to support the bottom of the pan are arranged at intervals on the flow guide plate. The deflector divides the gap between two adjacent heat exchange fins into an air inlet channel and an air outlet channel, and the guide vane includes an air inlet surface and an air outlet surface, and the air inlet surface and the corresponding Two adjacent heat exchange fins enclose an air inlet channel, and the air outlet surface and two adjacent heat exchange fins enclose an air outlet channel.

The deflector divides the gap between two adjacent heat exchange fins, so that the deflector and the heat exchange fins form two channels, and the air that provides oxygen for the gas during combustion passes through the lower channel. Entering, the burned flue gas flows out from the upper channel, and when the flue gas passes through the upper channel, it will exchange heat with the heat exchange fins, so that the heat in the flue gas can be transferred to the heat exchange fins, so that the heat exchange The fins can also be used as a heat source to heat the pot, which effectively utilizes the heat lost to the flue gas in the air, improves the thermal efficiency of the gas stove, and at the same time saves energy and protects the environment.

The heat exchange fins are bent sheets arranged in a swirl shape, and the center formed by the plurality of heat exchange fins is the space where the burner flame burns.

The heat exchange fins are bent and vortex-shaped so that the contact area between the flue gas and the heat exchange fins increases, but the size of the pot support does not increase, which is beneficial to the heat exchange between the flue gas and the heat exchange fins, and the heat exchange fins The sheet is still located on the outer ring side of the burner, leaving a space for the burner to burn in the middle.

The air inlet surface is concave, and the air outlet surface is convex.

The air deflector is placed in the middle of the heat exchange fins, and the inner ring of the air guide is lower than the outer ring.

The more regular design of hot air rising and cold air sinking makes the air circulation more smooth.

The bottom of the heat exchange fins is provided with support feet supported on the gas stove panel.

The contact between the heat exchanging fins and the panel of the cooker is small so that the heat will not spread to the panel too much.

The guide fins and the heat exchange fins are integrally formed.

The heat exchanging fins are evenly spaced and arranged radially on the deflector.

The pot support with the above-mentioned structure makes the pot be placed stably, can effectively improve the thermal efficiency of the gas cooker, and is environmentally friendly and energy-saving.

【Detailed ways】

The pot support shown in Figure 1 includes a flow guide 1 and heat exchange fins 2 arranged on the flow guide 1, the flow guide 1 is annular, and several heat exchange fins 2 are evenly spaced in turn. The arrangement on the deflector 1 is also ring-shaped (its overall shape is like the radiation of sunlight), and there is a space for the burner 4 to burn in the middle of the ring surrounded by the heat-exchange fins 2, and the heat-exchange fins 2 are bent The combination of the fins is in a vortex shape, and the heat exchange fins 2 are provided with support feet 21 that contact the panel 3 to support the entire pot bracket. Transferring to the panel causes waste of heat energy. As shown in Figure 2, the air guide 1 is located slightly above the middle of the heat exchange fin 2, so that the air guide 1 separates the heat exchange fin 2 into upper and lower parts and is connected with Two adjacent heat exchanging fins 2 form an air flow channel, and the deflector 1 has a small inclination angle, that is, the inner ring is lower than the outer ring, and the lower surface of the deflector 1 is a concave surface for the air inlet surface 11, and the upper surface is concave. The surface is that the air outlet surface 12 is convex. As shown in the practical state diagram of Figure 4, the pot support is placed on the gas stove panel 3, supported by the support feet 21, and the pot 5 to be heated is placed on the pot support, the bottom of the pot is in contact with the heat exchange fins 2, and the heat exchange The middle hole that fin 2 surrounds is directly facing the burner and can make the flame of the burner directly heat the bottom of the pan. The deflector 1 divides the gap between two adjacent heat exchange fins 2 into an air inlet channel and an air outlet channel, and the air inlet surface 11 and the two adjacent heat exchange fins 2 enclose an air inlet channel. The air outlet surface 12 and two adjacent heat exchange fins 2 form an air outlet channel, and the cold air B that provides oxygen for the combustion of the gas enters the burner position from the air inlet channel, and the burned flue gas C Flow out from the air outlet channel, and the waste heat is transferred to the heat exchange fins 2 when passing through the heat exchange fins 2, so that the heat exchange fins 2 can also heat the bottom of the pot, so that the thermal efficiency is improved, energy saving and environmental protection. The heat exchanging fins 2 are bent sheets, and their combination is in a vortex shape, which can increase the contact area between the heat exchanging fins 2 and the hot flue gas C, and make the heat exchange more thorough.
