Description

Technical Field

[0001] The utility model belongs to the field of gas stoves, and in particular relates to a double-layer energy-gathering pot rack and a gas stove. Background Art

[0002] With the development of society, gas stoves have become essential cooking appliances in modern families, and users' demand for their use is gradually increasing. How to improve the thermal efficiency of gas stoves has become an urgent problem to be solved.

[0003] Some gas stoves on the market solve the problem of thermal efficiency by setting up an energy-gathering pot rack. First, it isolates the cold air. After adding the energy-gathering pot rack, it can prevent too much outside air from entering the flame zone through convection and diffusion, thereby avoiding the decrease in flame temperature and heat transfer efficiency. It forms a high-temperature combustion area and heat exchange area between the energy-gathering cavity and the bottom of the pot, which can effectively promote the complete combustion of the gas and the heat transfer between the high-temperature flue gas and the bottom of the pot, and improve the heat exchange intensity. After adding the energy-gathering pot rack, the flue gas flows in the limited cross-section channel between the energy-gathering cavity and the bottom of the pot, which is beneficial to increase the speed of the flue gas flushing the pot body, increase the convection heat transfer coefficient, and thus improve the heat transfer between the flue gas and the pot body. Finally, it enhances thermal radiation. The energy-gathering pot rack absorbs the heat dissipated by the high-temperature flue gas to the outside world to increase its own temperature. The high-temperature energy-gathering ring then transfers the heat to the bottom of the pot through the radiation heat exchange between the fixed surfaces, which can convert part of the heat lost by the flue gas to the outside world into effective heat absorption by the pot body.

[0004] In order to ensure the integrity of the existing double-layer energy-gathering pot rack, the upper and lower energy-gathering plates are connected to each other. Because the upper plate is close to the flame and absorbs heat, with respect to the existing double-layer energy-gathering plate structure, heat is usually conducted from the upper layer to the lower layer through the connection part, resulting in heat loss.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a double-layer energy-gathering pot rack to avoid heat loss caused by heat transfer through the connection parts due to the integrated setting of the energy-gathering pot rack.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A double-layer energy-gathering pot rack, characterized in that it comprises a first pot rack and a second pot rack which are independently arranged.

[0009] The first pot rack is provided with a plurality of first brackets;

[0010] The second pot support is provided with a positioning groove corresponding to the first support;

[0011] The first bracket is clamped in the positioning groove, the first pot rack is coaxially arranged above the second pot rack, and an energy gathering chamber is formed between the first pot rack and the second pot rack.

[0012] Furthermore, the outer ring of the first pot support is spaced apart from the outer ring of the second pot support, and the inner ring of the first pot support is spaced apart from the inner ring of the second pot support.

[0013] Furthermore, the first pot support extends obliquely downward from the outer ring to the inner ring along the axial direction, and the second pot support extends in a bowl-shaped downward arc from the outer ring to the inner ring along the axial direction, and the bottom of the extended part of the first pot support conflicts with the second pot support to form an energy gathering chamber.

[0014] Furthermore, the first brackets are evenly arranged at the periphery in the circumferential direction and radially arranged, and the positioning grooves are arranged at the periphery of the second pot rack corresponding to the first brackets.

[0015] Furthermore, the first pot support is annular, and a water receiving ring groove is provided near the inner ring.

[0016] Furthermore, the first pot support extends obliquely downward from the outer ring to the inner ring along the axial direction, and extends obliquely upward near the inner ring along the axial direction to form the water receiving ring groove.

[0017] Furthermore, a plurality of second brackets are extended downwardly along the axial direction from the inner ring of the second pot support, the second brackets are supported on a fixed surface, and the bottom of the first bracket and the second bracket are at the same horizontal height.

[0018] Furthermore, the bottom of the first bracket is provided with a supporting foot.

[0019] A gas stove comprises the double-layer energy-gathering pot rack described above.

[0020] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0021] By spacing the independently arranged first pot rack and the second pot rack, heat loss due to solid heat conduction of the integrated double-layer energy-gathering pot rack is avoided. The first bracket cooperates with the positioning groove to limit the relative rotation of the first pot rack and the second pot rack. The energy-gathering cavity between the first pot rack and the second pot rack is used to insulate heat, thereby improving the efficiency of the gas stove. Furthermore, by providing a water receiving ring groove, liquid after overflowing the pot is prevented from flowing into the combustion zone of the gas stove and affecting the efficiency of the gas stove. Furthermore, by providing a drainage plate, liquid overflowing the water receiving ring groove is drained to prevent it from flowing into the combustion zone of the gas stove and affecting the efficiency of the gas stove.

The first pot rack 1 is located above the second pot rack 2 , and an energy-gathering chamber is formed between the first pot rack 1 and the second pot rack 2 .

[0035] In a further embodiment, the first pot stand 1 includes a pot stand body 12 and a first bracket 11, wherein the first bracket 11 is partially located above the pot stand body 12 and partially located below the pot stand body 12, and at least one positioning groove 22 is provided at the outer edge of the second pot stand 2, wherein the positioning groove 22 corresponds to the first bracket 11 located below the pot stand body 11, and the first pot stand 1 and the second pot stand 2 are coaxially arranged through the cooperation of the positioning groove 22 and the first bracket 11, and the first bracket 11 is supported to a fixed surface through the positioning groove 22, and the first bracket 11 can be connected to the first pot stand 1 by welding.

[0036] Specifically, the pot rack body 12 is annular, and four first brackets 11 are provided at the outer periphery. The outer periphery of the pot rack body 12 of the first pot rack 1 is spaced apart from the outer periphery of the second pot rack 2, and the inner periphery of the pot rack body 12 of the first pot rack 1 is spaced apart from the inner periphery of the second pot rack 2.
