Method for adjusting rotating speed of fan through linkage of electrical part and water-gas linkage valve

Abstract

The invention discloses a method for adjusting the rotating speed of a fan through linkage of an electrical part and a water-gas linkage valve. A shell is included, a smoke exhaust pipe is fixedly arranged in the middle of the top end of the shell, the resistance value of a potentiometer can be changed along with the rotation of a third gear, a fan is controlled to adjust different wind speeds, sothat the emission of smoke can be accelerated, the air-fuel ratio of a water heater is more reasonable, the heat efficiency is effectively improved, the purpose of saving energy is achieved, carbon monoxide emission is reduced, and the method is more environmentally friendly; an L-shaped plate not only ensures the stability of a connecting rod during rotation, and the connecting rod is preventedfrom sliding downwards, so that a first gear and a second gear are stably engaged with other gears; and fan blades can accelerate smoke exhaust and prevent smoke from flowing back, limiting blocks canprevent a cover plate from rotating excessively, external dust can be prevented from entering the fan through the smoke exhaust pipe, and the situation that normal use of the water heater is affecteddue to long-time dust accumulation is avoided.

Description

technical field [0001] The invention belongs to the technical field of water-air linkage valves, and in particular relates to a method for adjusting the rotational speed of a fan through electrical components and a water-air linkage valve. Background technique [0002] The water-air linkage valve, also known as the water-air linkage device, includes water control devices and air control devices. Regulating valves, solenoid valves, air inlets, etc. The function of the water-gas linkage device is to ensure that the gas control valve can only be opened when the water pressure is sufficient and is introduced into the heat exchanger to flow; and when the water flow stops or the pressure is insufficient, the gas supply path is automatically cut off to prevent water loss due to water shortage. Burn out the device. [0003] Existing ordinary forced-exhaust water heaters generally use a single-speed fan to forcibly exhaust smoke to the outside. During use, the thermal efficiency ma...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for adjusting the speed of the fan through the linkage of electrical components and water-gas linkage valves, so as to solve the problem mentioned in the background art that the existing common forced-exhaust water heater generally adopts a single-speed fan to force the smoke to be exhausted outwards. During use, the thermal efficiency may be low under small load conditions, and the wind speed of the fan cannot be automatically adjusted according to the actual working status of the water heater, which will not only cause unsatisfactory heat dissipation, but also not conducive to saving power; Externally, external debris or dust may enter the inside of the fan through the pipe, and after a long period of accumulation, it may block the exhaust pipe, causing inconvenience to the user
