Description

Technical Field

[0001] The present application relates to the technical field of gas stoves, and in particular to a premix gas stove. Background Art

[0002] There are currently two main types of commercial gas stoves. One is directly connected to the combustible gas for combustion, and the other is to premix the combustible gas and air, and then pass them into the premixed gas stove for combustion. The former is mainly used in households; the latter is mainly used in canteens, restaurants, hotels, food processing plants and other places. Its characteristics are high power, fast heating and fast tempering.

[0003] A search revealed Chinese patent application number CN220981391U, which discloses a premix gas stove for wok cooking. This system improves the mixing of air and gas by introducing mixed gas into a first annular chamber, where it is blocked by a baffle before being recoiled into a second annular chamber. However, this system relies on both the annular chamber and the baffle to achieve this mixing effect. The baffle primarily creates a recoil effect by blocking the flow of gas, forcing the gas to flow back and forth between the two annular chambers for mixing. However, this approach can result in uneven mixing in certain areas. Therefore, a premix gas stove has been proposed to address this issue. Utility Model Content

[0024] See also Figure 1-5 , the utility model provides a premix gas stove technical solution:

[0025] A premix gas stove includes a base 1, a burner base 2 is fixedly connected to the upper surface of the base 1, a burner outer cover 3 is fixedly connected to the upper surface of the burner base 2, a plurality of nozzles 4 are fixedly connected to the surface of the burner outer cover 3, an air outlet 5 is provided at the center of the upper surface of the burner base 2, a guide member is provided around the air outlet 5 on the upper surface of the burner base 2 to cause the gas ejected from the air outlet 5 to form a vortex, and a constraint member is provided around the guide member on the upper surface of the burner base 2 to constrain the vortex gas.

[0026] The flow guide member is a plurality of flow guide plates 6 arranged around the gas outlet 5 , and the plurality of flow guide plates 6 are arranged on the upper surface of the burner base 2 in a vortex shape.

[0027] A guide channel 7 is formed between two adjacent guide plates 6 .

[0028] Specifically, by providing a plurality of vortex-shaped guide plates 6, the original straight flow path of the mixed gas ejected from the gas outlet 5 can be changed, and the mixed gas is prompted to rotate along the guide plates 6, thereby forming a vortex, thereby causing the gas and air molecules to collide with each other and mix more fully.

[0029] The restraining member is a plurality of restraining baffles 8 arranged around the flow guide member. The restraining baffles 8 are arranged in a circular array on the upper surface of the burner base 2.

[0030] A delivery channel 9 is formed between two adjacent constraint baffles 8 , and the delivery channel 9 corresponds to the nozzle 4 .

[0031] Specifically, the restraining baffle 8 is provided to stabilize and restrain the vortex gas, and prevent the vortex gas from spreading to the surroundings too early, so that the gas and air are kept in a mixed state within a certain spatial range, so as to enable continuous and stable combustion.

[0032] It also includes a premixing pipe 10, one end of which is connected to the air outlet 5, and the other end of the premixing pipe 10 is connected to the external fan. A gas pipe 11 is fixedly connected to the surface of the premixing pipe 10, and the premixing pipe 10 is connected to the gas pipe 11.

[0033] The upper surface of the burner base 2 is fixedly connected with a flame head 12 and an ignition needle 13 respectively.

[0034] Specifically, a premixing pipe 10 is provided, air is introduced into one end of the premixing pipe 10 and gas is introduced into the gas pipe 11 so that the gas and air are premixed in the premixing pipe 10 , and the mixed gas is ignited by providing a flame head 12 and an ignition needle 13 .

[0035] Working principle: During the use of the premixed gas stove, air is introduced into one end of the premixed pipe 10 and gas is introduced through the gas pipe 11, so that the gas and air are premixed in the premixed pipe 10, and the premixed air and gas mixed gas is ejected from the gas outlet 5. A plurality of vortex guide plates 6 are used to change the original straight flow path of the mixed gas ejected from the gas outlet 5, so that the mixed gas is prompted to rotate along the guide plates 6, thereby forming a vortex, so that the gas and air molecules collide with each other and mix more fully. At the same time, the constraint baffle 8 stabilizes and constrains the vortex-shaped gas, preventing the gas that has formed a vortex from diffusing to the surrounding area too early, so that the gas and air remain in a mixed state within a certain spatial range, so that they can burn continuously and stably. The evenly mixed mixed gas enters the nozzle 4 through the delivery channel 9 and is ejected, and is ignited under the action of the flame head 12 and the ignition needle 13, so that the premixed gas stove has a better mixing effect.
