Description

Technical Field

[0001] The utility model relates to a gas heater with an intelligent frequency conversion regulation function. Background Art

[0002] Currently, most of the industrial gas heating on the market is used for animal husbandry and vegetable and fruit greenhouses. The internal temperature environment of the greenhouse is greatly affected by external weather changes. However, the industrial gas heaters currently on the market only have a single maximum power operation. Since the temperature of the actual use environment will change, running the heater at maximum power all the time will cause waste of resources and increase in costs. The current heaters mainly rely on their own temperature control system to sense changes in the surrounding temperature to stop or start the machine, but long-term frequent switching on and off has a great impact on the life of the entire machine and increases the risk of damage; and when turning the machine on and off, the gas fuel is not easy to fully burn, which not only leads to waste of gas, but also produces harmful gases that have adverse effects on humans and animals, and also increases the use cost of farmers.

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 4 As shown, a gas heater with intelligent variable frequency regulation function includes a base 100, which is square. A side wall 101 is arranged along the base 100, wherein an air outlet 103 is arranged below one of the side walls, and a plurality of rotating wheels 102 are arranged below the base 100 for moving the heater.

[0016] A controller 10 is provided inside the heater; an air intake pipe 1 is provided on the upper side of the base 100 near the air outlet 103, and a plurality of proportional valves 2 are connected to the tail end of the air intake pipe 1, and the front end of each proportional valve 2 is separately connected to the air intake pipe 1, and each proportional valve 2 adjusts the air intake amount according to the power requirement of the product design and is connected to the controller 10 through a wire; the rear end of the proportional valve 2 is connected to an air outlet pipe 3, and the tail end of the air outlet pipe 3 is connected to a gas nozzle 4, and a fire grate 5 is provided above the gas nozzle 4, and the gas from the gas nozzle 4 flows into the fire grate 5, and the upper end of the fire grate 5 is connected to a combustion chamber 8, and the fire grate 5 and the combustion chamber 8 are connected. The combustion chambers 8 are interconnected, and an ignition needle 6 is arranged between the fire grate 5 and the combustion chamber 8. The ignition needle 6 extends into the combustion chamber 8 to ignite the gas. A sensing probe 7 extending into the combustion chamber 8 is arranged on the side of the ignition needle 6. The sensing probe 7 is used to sense whether the gas is ignited. The sensing probe 7 is connected to the controller 10. When the sensing probe 7 does not detect flame burning, the controller 10 controls the heater to cut off power and controls the proportional valve 2 to close the intake pipe 1 to stop air intake; after the ignition needle 6 ignites the flame, the gas burns in the combustion chamber 8 and is converted into heat energy; the nozzle 4, the fire grate 5, and the combustion chamber 8 are all close to the side of the air outlet 103.

[0017] A fan assembly 9 is arranged on the other side of the base 100. The fan assembly 9 includes a fan and a multi-frequency motor. The multi-frequency motor is connected to the controller 10 to control the rotation speed of the fan assembly 9 to match the gas flow of the proportional valve 2. The matching wind speed can ensure the combustion time of the gas in the combustion chamber 8, ensure the full combustion of the gas, and improve the gas utilization rate. When the fan assembly 9 rotates, it blows the heat energy generated by the combustion chamber 8 to the air outlet 103, and the hot air reaches the external environment from the air outlet 103.

[0018] The controller 10 is provided with a temperature control system (not shown in the figure) that can sense the ambient temperature. When the ambient temperature is close to the set temperature, the controller 10 controls the multi-frequency motor and the proportional valve 2 to switch to a low gear to maintain a constant indoor temperature. When the ambient temperature is greater than the set temperature, the controller 10 controls the heater to shut down, which can prevent the gas from being blown out to the outside environment without being fully burned due to excessive wind speed, or prevent the product body temperature from being too high due to too low wind speed, thereby affecting the service life.

[0019] The utility model provides a gas heater with intelligent variable frequency regulation function. By arranging a controller 10, a plurality of proportional valves 2 connected to the controller 10 and a multi-frequency motor in the heater, each proportional valve 2 can adjust the air intake volume according to the power requirement of the product design, and the multi-frequency motor can adjust the speed of the fan assembly 9. The controller 10 senses the ambient temperature to control the air intake volume of the proportional valve 2 and adjusts the speed of the multi-frequency motor to match the air intake volume, thereby diversifying the heating mode of the heater, improving the utilization rate of the gas and extending the service life of the heater.
