Description

Technical Field

[0001] This utility model relates to a rotor-type burner with a spiral flame configured with rotor blades. This rotor-type burner is mainly suitable for commercial cooking stoves, large wok stoves, etc. Background Technology

[0002] Currently, the burners on traditional commercial cooking stoves and large wok stoves commonly produce a straight flame shape. This flame shape results in incomplete combustion and less than ideal thermal efficiency, consuming excessive energy and being environmentally unfriendly, thus proving unsatisfactory in practical use. Summary of the Invention

[0003] To overcome the shortcomings of traditional commercial cooking stoves and large wok stoves, such as incomplete combustion and unsatisfactory thermal efficiency, a rotary burner with a spiral flame is proposed. This burner is easy to use, has a reasonable structure, more complete combustion, more ideal thermal efficiency, and is energy-saving and environmentally friendly.

[0004] To achieve the above objectives, the technical solution of this utility model can be implemented as follows: A rotor-type burner head with a spiral flame, characterized in that the rotor-type burner head includes a burner head body with upper and lower air inlets, having at least one rotor with at least one rotor blade and at least one main burner; a burner head seat with at least one main air inlet hole and at least one main air inlet pipe fitting hole; and a burner head cover with at least one working condition fitting cavity and at least one furnace opening, having at least one constant flame and ignition electrode. The burner head seat is provided with a guide positioning fitting hole corresponding to the positioning fitting hole of the constant flame ignition burner and the positioning fitting hole of the igniter on the burner head body, which guides the constant flame air inlet pipe and the insulator of the igniter to be accurately inserted and positioned into the constant flame air inlet pipe. The number, relative positions, and positions relative to the central axis of the burner head are consistent and matched with the number and positioning holes of the constant flame air inlet pipe and the insulator of the burner. The spiral flame of the rotary burner is formed by the spiral airflow generated by the air force from the lower air inlet on the burner head driving the rotor blades to rotate. This spiral airflow mixes the flame from the upper fire hole of the main burner with the airflow to form the spiral flame. At the same time, the flame spirals upward and bursts out of the furnace opening to achieve the purpose of stir-frying and cooking.

[0005] The technical solution of this utility model can also be implemented as follows: A rotor-type stove head with a spiral flame and a rotor blade, characterized in that the rotor-type stove head includes a stove head body with an air inlet, a main burner, and an air inlet, and a stove head seat with at least one main air inlet hole and at least one main air inlet pipe through hole, and a stove head cover with at least one furnace opening, wherein the stove head seat is provided with a positioning hole corresponding to the positioning hole of the normally open flame ignition burner and the positioning hole of the igniter on the stove head body, which can guide the insulation of the normally open flame air inlet pipe and the igniter. The guide positioning groove accurately guides and positions the burner body. The number and relative positions of the guide positioning groove are consistent with and match the number and relative positions of the positioning holes of the constant flame ignition burner and the igniter on the main body of the burner. The spiral flame of the rotary burner is formed by the spiral airflow generated by the air force from the air inlet on the main body of the burner driving the rotor blades to rotate. This spiral airflow mixes the flame from the fire hole on the main burner with the airflow to form and generate the spiral flame. At the same time, the flame spirals upward and leaps out of the furnace opening to achieve the purpose of stir-frying and cooking.

[0006] Of course, to ensure reliable rotation between the rotor and the burner body, a bearing scheme can be used, where the rotor and bearing have an interference fit hole on the rotor and the connecting shaft on the burner body have an interference fit platform. Alternatively, a copper bushing scheme can be used, where the rotor's central axis stepped hole on the rotor and the stepped shaft connecting shaft on the burner body have a copper bushing between them. A copper tile scheme can also be used, where the rotor's central axis stepped hole on the rotor and the stepped shaft connecting shaft on the burner body have a copper tile between them, or other schemes that facilitate rotation. The ignition electrode A or B of the igniter can be a self-contained independent unit, or a composite unit formed by processing ignition electrode A and ignition electrode B with insulating material, or a combined unit assembled manually. The hexagonal shape on the main burner is for ease of operation; a hexagonal shape can be used... Octagonal shapes, cross-shaped grooves, straight grooves, internal hexagonal shapes, or other options are also acceptable. The angle between the centerline of the fire hole on the main burner and the central axis of the burner body is preferably controlled between 0° and 90°, with 25° to 50° being preferred. The angle between the furnace opening on the burner cover and the central axis of the burner body is preferably controlled between 0° and 30°, with 5° to 15° being preferred. The main air inlet on the burner seat can be connected to either a flexible hose or a rigid pipe, preferably a threaded rigid pipe. The constant flame ignition burner can be a self-contained independent unit, a composite unit where the constant flame air inlet pipe is machined into itself, or a combination unit assembled manually with the constant flame air inlet pipe, etc. During the assembly of the rotary burner, the main air inlet pipe and its through-hole on the burner seat are preferably sealed using a sealing ring or by applying sealant.

[0007] According to this utility model, a rotary burner head with a spiral flame is described. Its working principle and usage method are as follows: First, turn on the one-button start ignition switch, then open the constant flame valve. Through the coordinated action of the ignition electrode A (induction needle) and ignition electrode B (ignition needle) of the igniter, the constant flame on the constant flame burner is ignited. The constant flame then ignites the flame in the main burner's flame hole. Finally, adjust the main air valve and main gas valve. Through the coordinated action of the air and gas from the main air inlet and main gas pipe, with pre-matched pressure, magnitude, and flow rate, and the spiral airflow generated by the airflow from the air inlet on the burner body driving the rotor blades, the flame from the flame hole on the main burner mixes with the spiral airflow to form a spiral flame. This flame spirals upward and exits the furnace opening, achieving the purpose of stir-frying and cooking. After cooking, first close the main gas valve, then close the constant flame valve, and finally turn off the power switch.

[0008] A rotary furnace head with a spiral flame and a rotor can be made of various materials, such as metals and polymers, and can be manufactured through various processes, such as precision casting, machining, molding, injection molding, and die casting.

[0009] This utility model has the following main advantages: 1. It is easy to use and has a reasonable structure. The spiral flame it produces burns more completely and has a more ideal thermal efficiency, which is energy-saving and environmentally friendly; 2. The process is simple, the materials are readily available, and the cost is low; 3. It is interchangeable, universal, and can be standardized. Attached Figure Description

Then, the bearing, which has been assembled with the rotor, is aligned and inserted from the external thread end of the connecting shaft in the furnace body of the furnace head into the interference fit platform of the bearing, and then aligned and placed into place. Finally, the hexagonal body (8) on the main burner is aligned and the main burner is aligned and placed into place. The internal thread on the device is aligned and screwed into the external thread on the connecting shaft inside the furnace chamber of the burner body and tightened to lock. Then, the connecting bend is aligned and screwed into the external thread on the connecting shaft under the burner body and tightened to the correct position. The burner body is now assembled. The burner body is then aligned and placed into the positioning groove (35) on the burner body that mates with the burner seat through the positioning outer edge (32) that mates with the burner seat. The three assembly bolts are then aligned and passed through the assembly bolts on the burner body and the burner seat in sequence. After aligning the through holes and positioning them, the assembly nuts are screwed into the external threads of the three assembly bolts and tightened to lock them. Then, one end of the external wiring (45) of the ignition electrode, which is processed into a whole, is inserted into and passes through the positioning hole of the igniter on the main body of the burner and the guide positioning hole of the igniter insulator on the burner seat, and is connected and fixed. Then, the constant flame air inlet pipe is inserted from bottom to top and passes through the guide positioning hole of the constant flame air inlet pipe on the burner seat and the positioning hole of the constant flame igniter burner on the main body of the burner, and is tightened into a whole and fixed. Then, the direction and angle of the ignition electrode A, the ignition electrode B, and the constant flame igniter burner are adjusted and locked as required. Finally, the burner cover is placed into the positioning groove on the main body of the burner with the matching positioning flange (37) that matches the main body of the burner and is in place. That is, a rotor-type burner (1) with a rotor blade and a spiral flame is assembled. Before use, first align the rotary burner head with the positioning flange (28) on the burner head seat and install it on the stove.

Finally, install, inspect and adjust the main air intake system, constant flame air intake system, and electrical system respectively for use (preferably, seal the gap between the main air intake pipe through hole and the main air intake hole with sealant). When using, first turn on the one-button start ignition switch, then open the constant flame ignition valve. Through the coordinated cooperation of the ignition electrode A and the ignition electrode B of the igniter, the constant flame on the constant flame igniter burner is ignited. The constant flame then ignites the flame in the main burner hole. Finally, fine adjust the main air valve and the main gas valve.At this time, the air and gas from the main air inlet and main air pipe, with their pressure, size, and flow rate already matched, are coordinated and combined. The spiral airflow generated by the air force from the lower air inlet on the main body of the burner drives the rotor blades to rotate, which in turn drives the flame from the upper fire hole of the main burner to mix with the spiral airflow, thus forming and producing a spiral flame. At the same time, the flame spirals upward and bursts out of the furnace opening, achieving the purpose of stir-frying and cooking. After cooking, first turn off the main gas valve, then turn off the constant flame valve, and finally turn off the power switch.
