Description

Technical Field

[0001] The present invention relates to the technical field of gas stoves, and particularly to an efficient gas stove. Background Art

[0002] At present, when the gas stoves on the market are in use, the gas ejected from the burner cap cannot fully contact and mix with oxygen, and the used burner rack cannot guide and gather the flame, resulting in low thermal efficiency of the gas stove. And most of the burner heads in the gas stove are made of cast iron and cast aluminum materials. After long-term use, the cast iron burner head is prone to rust, affecting the use. Although the cast aluminum burner head solves the rust problem, once the gas stove has a flashback, it may burn the inner wall of the burner head, causing the burner head to deform or even melt, generating potential safety hazards. Moreover, the inner walls of the cast iron burner head and the cast aluminum burner head are rough, which is not conducive to the flow and mixing of gas and air. Summary of the Invention

[0003] Aiming at the problems that the gas in the gas stove cannot fully contact and mix with oxygen during use, the burner rack cannot effectively guide and gather the flame, resulting in low thermal efficiency of the gas stove, and the burner head is not conducive to gas flow, the present invention provides an efficient gas stove.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An efficient gas stove, comprising a stove body, a valve body, a burner head, a burner cap and a burner rack. The valve body is located in the stove body and is connected to the burner head. A stove hole is opened on the tabletop of the stove body, and a liquid receiving tray covering the stove hole is arranged on the tabletop. The end of the burner head passes through the liquid receiving tray and is sleeved with a burner cap seat, and the burner cap is arranged on the burner cap seat. The burner cap includes an inner burner cap and an outer burner cap, which can respectively form an inner ring cavity and an outer ring cavity corresponding to the burner cap seat. The burner head is independently communicated with the inner ring cavity and the outer ring cavity through pipelines respectively. The burner rack is in a disc shape, is sleeved outside the outer burner cap in a matching manner and is clamped with the liquid receiving tray. The edge of the burner rack adjacent to the outer burner cap extends upward, and its inner surface has several arc-shaped protrusions in a centrifugal shape.

[0006] Further, the liquid receiving tray is in a circular stepped shape, including a first step and a second step, and a clamping interface is formed by recessing from the top surface of the first step to the second step.

[0007] Further, the inner burner cap is a cylinder with an open lower part, has an annular groove on the upper part, has several arc-shaped protrusions in a centrifugal shape on the top, and has an upward extension along the arc-shaped protrusions at the top edge.

[0008] Further, the groove includes a first groove and a second groove. The first groove is an annular triangular groove, and a number of first fire holes inclined obliquely downward are provided on the lower side inside the first groove. The second groove is located below the first groove and inclined downward toward the lower part of the inner fire cap, and a number of second fire holes are provided on the lower side inside the second groove.

[0009] Further, the outer fire cap is frustum-shaped and has a through hole at the center that can be adapted to the inner fire cap. A number of first fire holes inclined obliquely downward are provided on the upper part of the outer side of the outer fire cap, and a third groove inclined obliquely downward is provided on the lower part of the outer side of the outer fire cap. A number of second fire holes are provided on the lower side inside the third groove.

[0010] Further, each of the first fire holes is inclined at a 45° angle, and each of the second fire holes is provided at the intermediate position between two adjacent first fire holes.

[0011] Further, a centrifugal-shaped protrusion is provided at the through hole of the outer fire cap.

[0012] Further, a number of upper support feet protruding vertically from the top are provided on the upper part of the inner side of the stove rack, and a number of lower support feet vertically arranged and adapted to the first step and the clamping interface are provided at the bottom.

[0013] The beneficial effects of the present invention are as follows: Both the burner head and the stove rack in the present invention are made of stainless steel materials, which are not easy to rust, and the inner walls are smooth, facilitating the rapid flow of gas. Through the optimized design of the first fire holes and the second fire holes in the fire cap, the present invention enables them to be arranged staggeredly, so that the gas and oxygen can fully contact and mix for combustion. At the same time, the centrifugal-shaped arc protrusions in the stove rack can guide and gather the flame to prevent it from spreading outward, enabling centralized heating of the bottom of the pot and improving the thermal efficiency.

[0020] Figure 7 As shown Figure 6 is a side view of Detailed implementation mode

[0021] The present invention discloses an efficient gas stove. The following describes a specific implementation mode of the present invention in conjunction with the accompanying drawings.

[0022] As Figure 1 shown, the efficient gas stove includes a stove body 1, a valve body, a burner head 2, a burner cap, and a stove rack 7. The valve body is detachably fixed inside the stove body 1. The valve body is connected to the burner head 2 through a pipeline and is controlled by a knob. Stove holes are opened on the left and right sides of the tabletop of the stove body 1. A liquid receiving tray 3 that can cover the stove holes is arranged on the tabletop. The liquid receiving tray 3 has a circular stepped structure, including a first step and a second step. The second step is higher than the first step and is located inside the first step. A clamping interface is formed by recessing from the top surface of the first step towards the second step. The stepped liquid receiving tray 3 can prevent sewage from entering the stove body 1, and at the same time enables the sewage to flow to the tabletop along the steps, facilitating cleaning. The burner head 2 and the stove rack 7 are both made of stainless steel materials, and the inner walls are smooth to avoid rust, which can enable the gas to flow quickly.

[0023] As Figure 2 shown, a burner cap seat 4 is sleeved on the end of the burner head 2 through the liquid receiving tray 3, and the burner cap is placed on the top of the burner cap seat 4. The burner cap includes an inner burner cap 6 and an outer burner cap 5. Combining Figure 3 and Figure 4 shown, the inner burner cap 6 is a cylinder with an open lower part, and has an annular groove on the upper part. The groove includes a first groove 601 and a second groove 602. The first groove 601 is an annular triangular groove, and several first fire holes are arranged along the axis in the lower side of the first groove 601 and are inclined downward at an angle of 45°. The second groove 602 is located below the first groove 601 and is inclined towards the lower part of the inner burner cap 6. Several second fire holes are arranged along the axis in the lower side of the second groove 602. The diameter of each second fire hole in the inner burner cap 6 is smaller than the diameter of each first fire hole, and each second fire hole is arranged at the middle position between two adjacent first fire holes. The top of the inner burner cap 6 has several centrifugal arc-shaped protrusions, and there is an upward extension along the edge of the arc-shaped protrusions at the top. As Figure 5 shown, the outer burner cap 5 is frustum-shaped, and has a through hole that penetrates up and down at the center position and can be adapted to the inner burner cap 6. Several first fire holes are arranged along the axis on the upper part of the outer side of the outer burner cap 5 and are inclined downward at an angle of 45°. The lower part of the outer side of the outer burner cap 5 has an inclined downward third groove, and several second fire holes are arranged along the axis in the lower side of the third groove. The diameter of each second fire hole in the outer burner cap 5 is smaller than the diameter of each first fire hole, and each second fire hole is arranged at the center position between two adjacent first fire holes. Centrifugal protrusions are arranged at the through hole of the outer burner cap 5. The first fire holes and the second fire holes are arranged in a staggered manner, so that the gas and oxygen can be fully contacted for combustion.

[0024] Combined with Figure 6 and Figure 7 As shown, the burner support 7 is a hollow structure in the shape of a disc, with a through hole at its central position. The burner support 7 is adaptively sleeved outside the outer burner cap 5 by means of the through hole, and the through hole of the burner support 7 extends upward adjacent to the edge of the outer burner cap 5. The inner surface of the burner support 7 has several centrifugal arc-shaped protrusions. The upper part inside the burner support 7 has several upper support feet 701 protruding vertically from the top of the burner support 7, and the bottom has several lower support feet 702 protruding vertically and adaptable to the first step and the clamping interface. The burner support 7 is clamped with the clamping interface by means of the lower support feet 702, which can prevent the burner support 7 from moving. The hollow structure of the burner support 7 can isolate cold air from entering the bottom of the pot and prevent the dispersion of flame heat. The arc-shaped protrusions in the inner burner cap 6, the outer burner cap 5 and the burner support 7 cooperate with each other to gather the flame to heat the bottom of the pot, improving the thermal efficiency.

[0025] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
