Description

Technical Field

[0001] The invention relates to the technical field of gas stoves, in particular to a base structure with a swirl air groove. Background Art

[0002] A gas stove refers to a kitchen appliance that uses liquefied petroleum gas (liquid), artificial coal gas, natural gas and other gas fuels for direct fire heating. A gas stove is also called a gas stove, stove plate, stove top, stove, and stove. Its popularity is well known to everyone. The gas needs to be mixed with air when it is transported. Generally, the gas is initially mixed with the air when it enters the burner of the gas stove. The mixed gas is then mixed again through the fire cover and continuously ejected to form continuous combustion. Secondary air needs to be introduced when mixing again.

[0003] When the existing gas stove is in use, the combustion of gas mixed with air will generate heat. The heat is transferred downward, causing the surrounding panel of the area where the burner is located on the gas stove to be continuously heated. As the heat is continuously transferred, the heated area will continue to expand, which is easy to affect people's use. For this reason, we have introduced a base structure with a swirl air groove. Summary of the invention

[0004] The object of the present invention is to provide a base structure with a swirl wind groove to solve the problem raised in the above background technology that the existing gas stove generates heat when in use due to the combustion of gas mixed with air, and the heat is transferred downward, causing the surrounding panel of the area where the burner on the gas stove is located to be continuously heated, and as the heat is continuously transferred, the heated area will continue to expand, which is easy to affect people's use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a base structure with a swirl air groove, comprising a premixing pipe and a base body, one side of the premixing pipe is connected to a blower, the base body is connected to the top of the premixing pipe, a burner secondary air supply port is provided at the edge of the base body, a primary air premixing port is provided on one side of the needle tube mouth, an air intake pipe plate is provided at the other edge of the base body, and threaded holes are provided on the inner side surface of the premixing pipe and the bottom of the base body.

[0006] Furthermore, the interior of the premixing pipe is in a ring shape and has symmetrically distributed linear grooves, and the premixing pipe is snap-connected with the base body.

[0007] Furthermore, the threaded holes are symmetrically distributed about the vertical center line of the premixing pipe, and the threaded holes on the inner side of the premixing pipe coincide with the threaded holes on the bottom of the base body.

[0008] Furthermore, outer ring air cavity curtain air outlets are provided on both sides of the base body, and the outer ring air cavity curtain air outlets are in a raised tubular structure.

[0009] Furthermore, a dry-burning prevention pipe opening is provided in the middle of the base body, and the dry-burning prevention pipe opening is circular.

[0010] Furthermore, needle nozzles are provided on both sides of the anti-dry burning nozzle, and the needle nozzles are symmetrically distributed about the vertical center line of the anti-dry burning nozzle.

[0011] Furthermore, an ignition needle is arranged inside one of the needle tube openings, and a sensing needle is arranged inside the other needle tube opening.

[0012] Furthermore, there are two air intake pipe interfaces on the surface of the air intake pipe plate, and the air intake pipe plate and the base body are integrated into one structure.

[0013] The present invention provides a base structure with a swirl air groove, which has the following beneficial effects:

[0014] 1. In the present invention, the base body is arranged on the lower surface of the glass panel of the gas stove, and air is injected into the premixing pipe by a blower.

[0021] The specific operation is as follows: after the premix pipe 1 and the base body 3 are engaged with each other, the threaded hole 10 on the inner side of the premix pipe 1 coincides with the threaded hole 10 at the bottom of the base body 3. At this time, screwing the bolt into the threaded hole 10 is conducive to firmly fixing the premix pipe 1 and the base body 3 together. The premix pipe 1 and the base body 3 can also be separated by unscrewing the bolt later, which is convenient for cleaning the inside of the premix pipe 1 later. The base body 3 is arranged on the lower surface of the glass panel of the gas stove. The blower 2 injects air into the premix pipe 1. The air will flow along the inside of the premix pipe 1. The air is cold air. When the gas stove is in use, the heat of combustion is transferred downward and absorbed by the glass panel. , and the upper surface of the base body 3 absorbs the heat of the glass panel and realizes heat exchange through the cold air inside the premixing pipe 1, so that the temperature of the surface of the glass panel can be reduced, thereby avoiding affecting people's use. The setting of the secondary air supply port 8 of the burner allows the air flowing in the premixing pipe 1 to flow out from here to the periphery of the inner ring fire cover for secondary air oxygen supplement, so that the gas in the inner ring fire cover can be fully burned. The gas pipe is connected to the air intake pipe plate 9, and the gas is transported to the fire hole of the fire cover through the air intake pipe plate 9. During the transportation process, the fan drives the air to pass through the primary air premixing port 7 to mix with the gas. The gas and air are mixed into primary air oxygen supplement and secondary air oxygen supplement, which can make the gas burn fully.

[0022] like Figure 1-2 As shown, outer ring air cavity curtain vents 4 are provided on both sides of the base body 3, and the outer ring air cavity curtain vents 4 are convex tubular structures;

[0023] The specific operation is as follows: the air flow inside the premixing pipe 1 also flows out through the outer ring air cavity curtain air outlet 4, and finally this part of the air flow flows to the periphery of the outer ring fire cover for secondary air oxygenation, so that the gas of the outer ring fire cover is fully burned.

[0024] like Figure 1 , Figure 3As shown, a dry-burn prevention pipe opening 5 is provided in the middle of the base body 3, and the dry-burn prevention pipe opening 5 is circular;

[0025] The specific operation is as follows: the interior of the anti-dry burning pipe mouth 5 is used to penetrate the anti-dry burning probe, that is, an infrared sensor or a laser sensor, and there is a gap between the anti-dry burning probe and the anti-dry burning pipe mouth 5 so that cold air rises along the air.

[0026] like Figure 1-3 As shown, needle nozzles 6 are arranged on both sides of the anti-dry burning nozzle 5, and the needle nozzles 6 are symmetrically distributed about the vertical center line of the anti-dry burning nozzle 5, an ignition needle is arranged inside one needle nozzle 6, and a sensing needle is arranged inside the other needle nozzle 6;

[0027] The specific operation is as follows: there are two needle nozzles 6 on the surface of the base body 3, one of the needle nozzles 6 is provided with an ignition needle, and the other needle nozzle 6 is provided with a sensing needle. The sensing needle senses whether the gas is gushing out. When the gas is sensed, the ignition needle is controlled to ignite the gas so that the gas burns at the fire hole of the fire cover.

[0028] In summary, when the base structure with the swirl air groove is used, first, after the premix pipe 1 and the base body 3 are engaged with each other, the threaded hole 10 on the inner side of the premix pipe 1 coincides with the threaded hole 10 at the bottom of the base body 3, and then the bolt is screwed into the threaded hole 10, which is conducive to firmly fixing the premix pipe 1 and the base body 3 together, and the premix pipe 1 and the base body 3 can be separated by unscrewing the bolt later, which is convenient for cleaning the inside of the premix pipe 1 later;

[0029] The base body 3 is arranged on the lower surface of the glass panel of the gas stove. The blower 2 injects air into the premixing pipe 1. The air will flow along the inside of the premixing pipe 1, and the air is cold air. When the gas stove is in use, the combustion heat is transferred downward and absorbed by the glass panel, and the upper surface of the base body 3 absorbs the heat of the glass panel and realizes heat exchange through the cold air inside the premixing pipe 1, so that the temperature of the surface of the glass panel is reduced, thereby avoiding affecting people's use.
