Gas water heater water channel distribution control device system and water channel distribution device

Abstract

The invention relates to a special water channel distribution device for a gas water heater, and aims to provide a gas water heater water channel distribution control device system and a water channel distribution device which are lower in failure rate, longer in service life and more stable in constant-temperature effect. The water channel distribution device comprises a water channel distributor, a central controller and a water flow sensor, the water flow sensor is used for detecting water inlet flow or water outlet total flow, a plurality of water channel branches are arranged on the water channel distributor and used for proportionally dividing a water channel of the water heater into a plurality of channels for distribution control, an electromagnetic valve is mounted on each water channel branch, and the water flow sensor and the electromagnetic valves are respectively and electrically connected with the central controller. The water channel distribution device is matched with a gas proportioning valve, a water inlet temperature probe and a water outlet temperature probe to form the gas water heater water channel distribution control device system, and the water inlet temperature probe and the water outlet temperature probe are used for detecting water temperatures.

Description

Technical field [0001] The invention relates to a gas water heater, in particular to a waterway diversion control device system and a waterway diversion device for a gas water heater. Background technique [0002] At present, the water circuit control used in thermostatic gas water heaters and heating stoves is a motor bearing driven back and forth rotation adjustment method; the characteristic is: the motor rotates proportionally according to the controller signal, and the bearing drives the water valve to rotate to control the water flow to achieve an auxiliary constant temperature. Disadvantages: 1. In this way, only a single motor controls the only waterway. Once a fault occurs, the constant temperature cannot be assisted. 2. This kind of motor bearing drives the rotation adjustment method. When the water pressure is unstable, the motor frequently rotates back and forth, and the motor is easy to heat, which will affect the life of the motor itself. Then during the frequent ba...

Problems solved by technology

Disadvantages: 1. This method only has a single motor to control the only waterway. Once a fault occurs, it cannot assist in constant temperature

2. This kind of motor bearing drives the rotation adjustment method. When the water pressure is unstable, the motor rotates frequently back and forth, and the motor is prone to heat, which affects the life of the motor itself. Then, during the frequent back and forth rotation of the motor, the motor bearing gear and the water valve shaft Gears rub against each other causing damage, paralysis

Friction between the water valve core and the water valve wall, loosening due to wear, or two-axis eccentricity will not be able to assist constant temperature

3. During the use of this structure, debris and scale in the water are easy to get stuck in the bearing movement, resulting in damage
