Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a stir-fry burner. Background Art

[0002] A burner is a device used to mix fuel and air and burn them under suitable conditions. It is commonly found in equipment such as gas stoves, boilers and engines.

[0003] The one-button stir-fry burners on the market make it difficult to heat the bottom of the pot evenly when the stir-fry function is turned on. The disadvantages are as follows:

[0004] 1. Most stir-fry methods use open flames to instantly heat the bottom of the pot, but the heating range of open flames is limited, and the bottom of the pot cannot be heated quickly and evenly.

[0005] 2. The air intake method for stir-frying is mostly a single upper and lower air intake. The nozzle of the stir-fry fire not only delivers gas but also injects air. Since the nozzle is placed in the same plane space (above or below the bottom cup), the air is easily disturbed or insufficiently supplied, resulting in incomplete combustion, excessive CO, low flame temperature, low bottom temperature of the pot, and failure to achieve the stir-fry firepower required by users.

DETAILED DESCRIPTION

[0030] The utility model embodiment provides a stir-fry burner, such as Figure 1-6 As shown, it includes three mixed combustion modes of stir-fry fire, high fire and low fire, which are composed of a bottom cup, a mixing seat, a high fire cover, a low fire cover, an ignition needle and a thermocouple. The ignition needle and the thermocouple are installed on the bottom cup, and the mixing seat is placed on the bottom cup with the ignition needle and the thermocouple boss on the bottom cup as guides. The high fire cover and the low fire cover are placed on the mixing seat respectively. It is characterized in that: the stir-fry fire combustion mode is infrared combustion, and the high fire and low fire combustion modes are open flame combustion, which adopts open flame and infrared radiation mixed combustion, and the infrared stir-fry fire has countless fire holes, which can evenly distribute heat energy to each fire hole of the combustion plate, and the heat energy of the fire holes is evenly radiated to the bottom of the pot, which can instantly increase the temperature of the bottom of the pot and keep it consistent, and the bottom of the pot is heated evenly.

[0031] To implement the above technical solution, specifically, Figure 2-5 As shown, the three mixed combustion modes are realized by the gas flow paths of the air inlet, nozzle, connecting port, mixing cavity, and combustion hole respectively. The air inlet of the stir-frying combustion mode is not in the same plane space as the high and low fire combustion modes. The high and low fire combustion modes are the upper air inlet in the same plane space, such as Figure 2 As shown, stir-frying over high heat or low heat and full air intake from top and bottom, the nozzles do not interfere with each other when inhaling air, the combustion is complete, the emission of toxic gases is low, and the harm of toxic gases (carbon monoxide, nitrogen oxides, etc.) to the human body is effectively reduced; in the embodiment of this case, the stir-frying fire combustion mode is subdivided into stir-frying over low heat and stir-frying over high heat, making the burner more applicable and suitable for more cooking modes.

[0032] Correspondingly, such as Figure 2 As shown, the base cup is provided with four independent air inlets, namely a high-fire air inlet, a high-fire stir-fry air inlet, a low-fire air inlet, and a low-fire stir-fry air inlet. The ends of the air inlets are connected to independent nozzles for delivering gas, namely a high-fire nozzle, a high-fire stir-fry nozzle, a low-fire nozzle, and a low-fire stir-fry nozzle. The gas from the air inlets is respectively injected into the corresponding channels of the base cup at a certain speed, and air is also sucked in by the injection force of the nozzle to form an air-fuel mixture.

[0033] like Figure 2-4 As shown, the bottom cup is provided with a high-fire stir-fry connecting port, a low-fire stir-fry connecting port, a high-fire connecting port and a low-fire connecting port, and the mixing seat is provided with four-ring cavities, which, from outside to inside, are a high-fire mixing cavity, a high-fire stir-fry mixing cavity, a low-fire mixing cavity and a low-fire stir-fry mixing cavity, respectively. The air-fuel mixture enters the corresponding cavity of the mixing seat through the corresponding connecting ports of the bottom cup.

[0034] Further, such as Figure 5As shown, a high-fire stir-fry burning plate is embedded in the high-fire cover, and two rings of independent combustion holes are arranged on the high-fire cover, namely, a high-fire combustion hole and a high-fire stir-fry burning plate. The high-fire combustion hole is arranged on the circular side wall of the high-fire cover, and its shape can be a circular hole or a strip groove. A plurality of fire holes are opened on the high-fire stir-fry burning plate. The material of the high-fire stir-fry burning plate can be ceramic or metal. The high-fire combustion hole corresponds to the high-fire mixing cavity, and the high-fire stir-fry burning plate corresponds to the high-fire stir-fry mixing cavity.

[0035] Further, such as Figure 6 As shown, the small fire cover is embedded with a small fire stir-fry combustion plate, and the small fire cover is provided with two rings of independent combustion holes, namely the small fire combustion hole and the small fire stir-fry combustion plate. The small fire combustion hole is arranged on the circular side wall of the small fire cover, and its shape can be a circular hole or a strip groove. The small fire stir-fry combustion plate is provided with a plurality of fire holes. The material of the small fire stir-fry combustion plate can be ceramic or metal.

[0036] In addition, the ignition needle is screwed onto the corresponding connection hole via its own thread; similarly, the thermocouple is screwed onto the corresponding connection hole via its own thread.

[0037] The working principle or steps are as follows:

[0038] 1. First, input gas through the air inlets for high heat, low heat, high heat stir-fry, and low heat stir-fry set on the bottom cup. Each of them can be controlled to achieve single or multiple channels to input gas at the same time;

[0039] 2. Each ring nozzle injects the gas from the air inlet into the corresponding channel of the bottom cup at a certain speed, and also inhales air by the injection force of the nozzle to form an air-fuel mixture;

[0040] 3. The air-fuel mixture enters the mixing cavity of the mixing seat through the corresponding connecting port of the bottom cup;

[0041] 4. The mixing seat mixes the air and gas fully and evenly distributes them to the large and small fire covers;

[0042] 5. The air and gas flow out from the fire holes of the large and small fire covers at a certain speed, and also bring a part of the air as a combustion source;

[0043] 6. The ignition needle is an essential ignition source for combustion, which will ignite the fire hole of the small fire cover to form combustion;

[0044] 7. Stir-frying fire can only burn when the low fire is in the working state. Other fire rings must be ignited from the low fire cover as the ignition source;

[0045] Note: A thermocouple is installed on the bottom cup. After installation, it is close to the fire outlet of the small fire cover. The thermocouple converts thermal energy into electrical energy, and uses the generated thermoelectric potential to maintain the opening of the gas passage to achieve continuous gas supply and combustion.

[0046] To sum up, the stir-fry burner has improvements in the stir-fry combustion method and the air intake method: Stir-fry combustion method: the present invention adopts a mixed combustion of open flame and infrared radiation. The infrared stir-fry fire has countless fire holes, which can evenly distribute heat energy to each fire hole of the combustion plate. The heat energy of the fire holes is evenly radiated to the bottom of the pot, which can instantly increase the temperature of the bottom of the pot and keep it consistent, and the bottom of the pot is heated evenly; the air intake method for stir-frying combustion adopts full air intake, and both high-fire stir-frying and low-fire blasting have independent channels that are not in the plane space with the high and low fires to supply air. The stir-fry fire and other fire rings do not interfere with the air required, and can fully and independently burn, with low CO emissions, high flame temperature, and high and uniform heating temperature of the pot bottom.

[0047] The utility model can not only effectively solve the user's demand for stir-frying, but also make the bottom of the pot evenly heated while heating instantly; in addition: because the infrared stir-frying fire adopts the flameless combustion principle and adopts the full air intake method, there is no visible open flame or a small amount of open flame during combustion, thereby effectively reducing the emission of toxic gases (carbon monoxide, nitrogen oxides, etc.) generated during combustion.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
