Description

Stove frame for energy-saving gas stove

Technical field

The utility model belongs to a gas appliance, in particular to a stove frame for a gas stove that can effectively prevent heat loss and improve combustion heat efficiency.

Background technique

Existing gas stoves, especially built-in gas stoves, usually have relatively high stove racks to adapt to pots of different shapes, so the heat dissipation area is large, and the heat generated by combustion is easily lost through the gaps in the stove rack, resulting in low combustion thermal efficiency. , the waste of energy is serious, and a large amount of heat is directly emitted into the air, and long-term accumulation will accelerate the greenhouse effect of the earth and accelerate the destruction of the environment.

Utility model content

The problem to be solved by the utility model is to provide a stove frame for a gas stove that can effectively prevent heat loss and improve combustion thermal efficiency.

The problem to be solved by the utility model can be realized through the following technical solutions: an energy-saving stove frame for gas stoves, including an annular base and at least three supports, and a support platform is formed on the support fixed base, which is characterized in that : the support is covered with a retaining ring that makes the space surrounded by each support circumferentially closed, and the top end surface of the retaining ring is flush with or lower than the top end surface of each support.

When in use, place the pot and pot on the support platform formed by the supports. The heat generated by the combustion of the gas stove is blocked by the retaining ring, and the hot air can only be dissipated outward through the gaps at the upper and lower ends of the retaining ring. Much smaller, so less heat is lost, and most of the hot air is trapped inside the ring, heating the bottom of the pot.

On the basis of the above, the utility model can be improved as follows: the retaining ring has at least two layers, and there is a space between the retaining rings of two adjacent layers for the air inlet. When the outside air enters the innermost retaining ring through these gaps, it contacts the wall of the retaining ring for heat exchange and the temperature rises, further improving the heat utilization rate.

The height of the multi-layer retaining rings decreases from the inside to the outside; so that the outside air can enter the space between the retaining rings.

As a preferred embodiment of the present invention, the retaining ring has two layers, and the height of the outer retaining ring is 2/3 of the height of the inner retaining ring.

The end face of the top of the innermost retaining ring is non-planar; as a preferred mode of the present invention, the end face of the top of the innermost retaining ring is a wave surface; some pots and pots are placed on the support formed by the support After the platform, its bottom may be in contact with the top of the innermost retaining ring, and the end surface of the innermost retaining ring top is made non-planar, which can ensure that the lower part of the end surface (that is, the trough) forms the air connecting the inside and outside of the retaining ring Channel; and designed as a wavy surface can reduce the stress concentration on the top of the retaining ring.

The bottom of each retaining ring described in the utility model is fixed on the base or the support.

As an embodiment of the present invention, the base is a square ring, the retaining ring is circular, the top of the base is covered with a sealing plate, and the sealing plate is connected to the outer wall of the outermost retaining ring.

As another embodiment of the present utility model, the base is a circular ring, the retaining ring is circular, and the base is provided with several radial protrusions, the outermost retaining ring has a size corresponding to the base, and the bottom of the retaining ring is fixed on the base, and the rest of the retaining ring is fixed on the protruding piece.

The structures of the above two embodiments make the gaps between the bottom ends of the retaining rings and the base all be closed, so as to reduce the passage of outside air entering the interior of the retaining rings, and force the external air to enter the innermost part through the gaps between the multi-layer retaining rings. within the retaining ring.

The support in the utility model is evenly distributed on the base in the circumferential direction and is in contact with the inner wall of the innermost retaining ring.

Compared with the prior art, the utility model can effectively prevent heat loss, improve the thermal efficiency of combustion, save energy, and reduce adverse effects on the environment; moreover, the utility model is simple in structure, low in cost, easy to use, and does not need to be adjusted by the user , easy to promote.

Detailed ways

The energy-saving stove frame for gas stoves shown in Figure 1 is an embodiment 1 of the present utility model, which includes a square annular base 1 and four supports 2, wherein the four supports 2 are evenly distributed in the circumferential direction and fixed on the base 1 To form a support platform, a layer of circular retaining ring 3 is set on the support 2 to close the space surrounded by each support 2 in the circumferential direction. The retaining ring 3 is made of multi-layer composite material, and the inner side of the retaining ring is made of metal material . The retaining ring 3 is also fixed on the base 1, and the inner wall of the retaining ring 3 is in contact with each support 2, and the end face of the retaining ring 3 top is a wave surface not higher than the top end face of each support 2 (that is, the top end face of the retaining ring is in contact with each support 2). the top end of the support is flush with or below the top end of each support).

The energy-saving stove frame for gas stove as shown in Figure 2 is embodiment 2 of the present utility model, and it differs from embodiment 1 in that: two layers of circular retaining rings 3 are provided, and the inner retaining ring is made of metal material Made, the outer retaining ring is made of non-metallic material; There is a space used as an air inlet between the two retaining rings 3 . The bottoms of the two retaining rings 3 are fixed on the base 1 or the support 2, and the inner wall of the inner retaining ring is in contact with each support 2, wherein the end face of the top of the inner retaining ring is wave-shaped, and the top end face of the outer retaining ring is flat, And the height of the outer retaining ring is 2/3 of the height of the inner retaining ring. The top of the base 1 is covered with a sealing plate 4, and the edge of the sealing plate 4 located inside the base 1 is connected with the outer wall of the outer retaining ring.

The energy-saving gas cooker hob as shown in Figures 3 to 4 is Embodiment 3 of the present utility model, and its difference from Embodiment 2 is that the base 1 is a ring, which is provided with a number of radial protrusions 5, The size of the outermost retaining ring is corresponding to the base, its bottom is fixed on the base, and the rest of the retaining rings are fixed on the protruding part 5 .
