Description

Energy-saving devices for gas cookers

technical field

The utility model relates to a gas cooker, in particular to an energy-saving device for the gas cooker.

Background technique

The current domestic gas stoves mostly use open pot supports, resulting in low temperature in the combustion zone, uncontrollable secondary air supply, excessive secondary air supply takes away heat, large flame radiation, and high stove surface temperature. The heat loss is large, which has a great impact on the thermal efficiency of the stove. Authorized notification number CN2669036Y discloses a conical surface heat-collecting pot support, which is composed of a main cone and supporting feet. The combustion quality and combustion efficiency of the gas cooker are greatly improved. The conical surface of the main cone can prevent heat from flowing The external radiation is close to the open flame, and may be in contact with the transparent outer flame of the flame, resulting in a high temperature rise of the pot support itself, reaching above 450°C, and the heat generated by combustion is lost by it too much, resulting in a decrease in thermal efficiency.

Contents of the invention

The purpose of the utility model is to solve the deficiencies of the prior art, and provide an energy-saving device for a gas cooker with a simple structure, which promotes more complete combustion of gas, further improves thermal efficiency and reduces exhaust gas emissions.

The utility model is realized through the following technical scheme: the energy-saving device of the gas cooker includes an energy-saving plate placed above the panel of the cooker, the energy-saving plate is in the shape of a basin, and there is an empty hole in the middle of the bottom of the plate, and the edge of the empty hole is close to the burner. The burner also forms a secondary air intake ring, and a support device is supported under the energy-saving disk to form a secondary air channel.

The utility model can also be completed in the following manner:

In the aforementioned energy-saving device for a gas cooker, the edge of the empty hole in the middle of the bottom of the energy-saving disk is a flat plate or a plate extending downward in a conical shape;

The supporting device is a supporting foot fixedly connected to the energy-saving disk;

The energy-saving device of the gas cooker also includes a pot foot piece, which is placed on the energy-saving plate by being fixedly connected to the pan frame ring, or the pot foot piece is directly fixed to the energy-saving plate, or the pot foot piece is movably inserted in the energy-saving plate. on the plate;

The fixing method of the pot foot piece and the energy-saving plate is riveting, welding or screw connection;

The supporting device is a pot foot piece, and the energy-saving plate is embedded in the pot foot piece; the pot foot piece is fixedly mounted on the pan frame ring.

The energy-saving device of the gas cooker of the utility model adopts the basin-shaped energy-saving plate and the support device below it to form a secondary air channel and a secondary air intake ring, so as to reduce the cooling of the combustion area by the surrounding air and take away heat, preventing the cooling of the cold air. There is no complete combustion of CO, so that the gas can be burned more fully; the basin-shaped energy-saving plate can increase the temperature of the combustion area and prevent the flame from radiating too much heat; to reduce the temperature rise of the stove surface, the energy-saving plate adopts a basin-shaped structure, especially the bottom of the plate For sinking or leveling, the distance between the energy-saving disc body and the open flame can be increased to prevent the flame of gas burning from directly contacting the energy-saving disc. The energy-saving disc does not absorb too much heat, and the temperature is controlled below 250°C. The loss is small, and the transparent outer flame has enough combustion space to make the combustion more complete, the combustion thermal efficiency can be increased by 10%, the smoke emission can be reduced by 70%, and the energy saving effect is obvious. The pot foot sheet of the utility model can also be combined with the energy-saving tray in various forms, which is convenient, practical and firm. The utility model is suitable for various household gas cookers, in particular suitable for embedded household gas cookers.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Embodiment 1, as shown in Figure 1, the energy-saving device for a gas cooker includes a basin-shaped energy-saving disk 1. An annular plate extending in a conical shape, the edge plate of the hole 12 is close to the burner of the burner 4 and forms a secondary air intake ring 13 between the burner 4, and four support feet 2 are fixed under the bottom 11 of the plate. 2 is placed on the panel 6 of the gas cooker, and the secondary air channel 7 is formed between the bottom 11 of the energy-saving panel 1 and the panel 6. An integral pot support is placed inside the energy-saving tray 1, and the four pot foot pieces 3 are evenly fixed on the pot frame ring 31. The bottom of the pot frame ring 31 has a groove 32 to reduce its own weight and reduce its heat absorption. . The outer ring 14 of the energy-saving disc 1 is a decorative ring.

Embodiment 2, as shown in Figure 3, the difference between the energy-saving device of the gas cooker and the embodiment 1 is that the pot support ring is canceled, and the pot foot piece 3 passes through the bottom 11 of the energy-saving disk 1 through the positioning pin 33 and is movably inserted in the Inside the support foot 2, the positioning is realized by plugging the positioning pin 2 34 with the energy-saving tray 1, and the pot foot piece 3 is easy to install and remove, which is convenient for installation and cleaning. It may also be that the pot foot piece 3 is directly connected to the energy-saving disk 1 by means of riveting, welding or screwing. Canceling the pot support ring can make the pot support itself absorb less heat.

Embodiment 3, as shown in FIG. 4 , is an energy-saving device for a gas cooker, which is different from Embodiment 1 in that the edge of the hole 12 in the middle of the bottom 11 of the energy-saving disk 1 is a flat plate.

Embodiment 4, as shown in FIG. 5 , is an energy-saving device for a gas cooker whose supporting device is a pot leg. The difference from Embodiment 1 is that the pot leg 3 replaces the support leg 2, and the pot support ring 31 is placed on the cooker panel 6 , the energy-saving disc 1 is embedded in the pot foot piece 3.

When the stove is in use, the gas flows out from the burner port of the burner 4 and burns, and the secondary air enters from the secondary air passage 7 below the energy-saving disk 1 and is supplemented into the combustion flame through the secondary air intake ring 13, so that the gas burns fully. The energy-saving disk 1 adopts a basin-shaped structure, especially when the bottom 11 of the disk is a sinking or flat plate structure, the distance between the body of the energy-saving disk 1 and the open flame can be increased, and the flame of burning gas is prevented from directly contacting the energy-saving disk 1, reducing The energy-saving disk 1 absorbs excessive heat, and the heat loss is small.
