[0033] A premix stove is characterized by comprising a base 100, a stove shell 200, a stove head 300, an air inlet pipe 301, a micro fan, an ignition assembly and a bracket 400.
[0034] The base 100 is a truncated cone structure, which can effectively increase the contact stability between the stove and the placement plane. A plurality of support legs 101 are evenly distributed at the bottom, and the bottom of each support leg 101 is provided with anti-skid grooves to further enhance the stability of the stove when placed and prevent the stove from sliding during use. The top surface of the base 100 is provided with a plurality of mounting holes 102 for mounting and fixing, which is convenient for assembly and fixing with other components.
[0035] The furnace shell 200 is fixedly connected to the mounting hole 102 on the top surface of the base 100 by screws, and the connection method is stable and reliable. The furnace shell 200 is made of high temperature resistant and corrosion resistant metal materials, such as ductile iron precision casting, which is strong and durable, can withstand high temperature environment, ensure the service life of the stove, and is not easy to be corroded. The top surface of the furnace shell 200 is provided with a boss 201 for supporting the pot, so that the pot can be placed more stably. A burner head 300 is installed inside the furnace shell 200, and the burner head 300 is fixed in the middle position of the furnace shell 200; one side of the burner head 300 is connected to the air inlet pipe 301, and the air inlet pipe 301 is used to transport gas to the burner head 300. A micro fan for transporting air into the air inlet pipe 301 is installed at the end of the air inlet pipe 301. The micro fan is a variable speed fan. The amount of air transported is controlled by adjusting the speed of the fan, so that the gas and air are accurately premixed in the air inlet pipe 301 to ensure a good combustion effect.
[0036] A bracket 400 is installed on the side of the furnace shell 200. The bracket 400 is an L-shaped structure. This structural design does not take up too much space and can effectively support and arrange related components. The air intake pipe 301, the micro fan and the ignition assembly are all located below the bracket 400. A flow regulating valve 401 and an ignition switch 402 are provided on the side of the bracket 400 away from the furnace shell 200. The flow regulating valve 401 is used to adjust the flow of gas, and the user can flexibly adjust the firepower according to cooking needs; the ignition switch 402 facilitates the user to perform ignition operations.
[0037] The micro-blower and the ignition assembly are both connected to a control module, and the control module includes a controller, a sensor assembly, and a power module;
[0038] Controller: As the core of the entire micro fan control system, it usually uses a microprocessor or a single chip microcomputer. It can receive signals from the sensor components and control the operation status of the micro fan according to the preset program and algorithm. For example, when the stove ignition signal is detected, the controller will quickly start the micro fan and adjust the speed of the micro fan according to the preset gas and air mixing ratio to ensure the best premixing effect of gas and air in the intake pipe.
[0039] Sensor assembly: contains a variety of sensors, mainly gas concentration sensors and air flow sensors. The gas concentration sensor is installed near the burner head of the intake pipe to monitor the concentration of gas in the intake pipe in real time.
[0040] The air flow sensor is installed at the air outlet of the micro fan to accurately measure the air flow entering the intake pipe and transmit the data to the controller so that the controller can accurately control the gas input according to the air flow to ensure that the gas and air always maintain a suitable mixing ratio.
[0041] Power module: Provides stable power for the entire micro fan control system. It can convert external mains power (such as 220V AC) into DC voltage (such as common 12V, 24V, etc.) suitable for the operation of controllers, sensors and micro fans. At the same time, the power module also has overvoltage protection, overcurrent protection and filtering functions to prevent damage to the control system due to voltage fluctuations, excessive current and other problems, ensuring that the entire system can operate stably and reliably.
[0042] The stove head 300 includes a plurality of fire holes 302, and a fire gathering ring 303 is installed on the stove head 300. The fire gathering ring 303 is a ring structure. The flames ejected from the fire holes 302 are distributed in the fire gathering ring 303. The fire gathering ring 303 can gather the flames, improve the heat utilization rate, and make cooking more efficient.
[0043] The ignition assembly includes an igniter and an ignition needle. The igniter is electrically connected to the ignition needle. The ignition needle is located above the burner head 300. The high voltage electricity generated by the igniter causes the ignition needle to discharge, thereby igniting the mixed gas. The ignition method is simple and reliable.
[0044] Assembly process:
[0045] Place the base 100 at a suitable location, ensuring that the support feet 101 are in stable contact with the placement surface.
[0046] The furnace shell 200 is fixedly connected to the mounting hole 102 on the top surface of the base 100 by screws.
[0047] A furnace head 300 is installed inside the furnace shell 200 , and an air inlet pipe 301 is connected to the furnace head 300 .
[0048] The micro fan is installed at the end of the air inlet pipe 301 to ensure that it can normally transport air into the air inlet pipe.
[0049] An L-shaped bracket 400 is installed on the side of the furnace shell 200 , and the air inlet pipe 301 , the micro fan and the ignition assembly are placed below the bracket 400 .
[0050] A flow regulating valve 401 and an ignition switch 402 are installed on a side of the bracket 400 away from the furnace shell 200 .
[0051] A fire focusing ring 303 is installed on the burner head 300 .
[0052] The igniter is electrically connected to the ignition needle, and the ignition needle is installed at a suitable position above the burner head 300.
[0053] Usage process:
[0054] Open the gas valve and adjust the gas flow to a suitable size through the flow regulating valve 401.
[0055] According to cooking needs, the speed of the micro fan is adjusted to control the amount of air delivered to achieve premixing of gas and air.
[0056] When the ignition switch 402 is pressed, the igniter generates high voltage electricity to discharge the ignition needle, igniting the premixed gas in the intake pipe. The flame sprays out from the fire hole 302 of the burner head 300, distributes in the fire gathering circle 303, and heats and cooks the pot placed on the boss 201 on the top surface of the furnace shell 200.
[0057] During the cooking process, the fire power and the mixing ratio of gas and air can be adjusted at any time according to the actual situation through the flow control valve 401 and the speed of the micro fan.
[0058] The premix stove of the present invention adopts a fan to assist combustion, so that the gas is fully burned, which is energy-saving and environmentally friendly; and the ignition assembly 1,
[0059] With flameout protection device, it uses low-pressure gas or pipeline natural gas, which is safe and reliable; one-button operation, pulse ignition, simple and convenient, strong firepower, and improved work efficiency; suitable for frying, deep-frying, steaming, stewing, etc. This stove thoroughly improves and solves the defects of existing cast iron stoves on the market, such as inability to use low-pressure gas, incomplete combustion, too high flame, weak and weak, too dangerous, and low work efficiency. It not only improves combustion efficiency and safety, but also simplifies the operation process. It is suitable for a variety of cooking needs and has a broad market application prospect.
