Gas water heater with water flow induction anti-soaking function and anti-soaking method

Abstract

The invention relates to a gas water heater with a water flow induction anti-soaking function and an anti-soaking method. The gas water heater comprises a functional assembly with a water body conveying function and / or a water body storing function, an electric valve used for connecting or disconnecting a water path of the functional assembly, and a control mainboard used for controlling the electric valve, wherein the electric valve is arranged on the water path of the functional assembly, and the electric valve is electrically connected with the control mainboard. The gas water heater is characterized by further comprising a water flow sensor used for detecting whether a water body flows on the water path or not, the water flow sensor is arranged on the functional assembly, and the waterflow sensor is in communication connection with the control mainboard. The gas water heater can detect whether water leaks or not, so that timely treatment is facilitated, and the soaking condition is prevented.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a gas water heater with a water flow sensing anti-soaking function and an anti-soaking method. Background technique [0002] Existing gas water heaters on the market generally have antifreeze models and non-freeze-proof models. Non-freeze-proof models are generally used in the southern region, and anti-freeze models are generally used in the northern regions. Among them, the antifreeze device of the antifreeze model generally uses electric heating to protect the coil on the heat exchanger (water tank); its biggest disadvantage is that in the severe cold weather in winter in the north, the antifreeze device will fail if there is a power failure If it is serious, it will even cause the coil to freeze and crack; normally installed water heaters are connected to the tap water pipe, but when the coil freezes and cracks, water leakage will occur; if it is not found in time, the water heater will b...

Among them, the antifreeze device of the antifreeze model generally uses electric heating to protect the coil on the heat exchanger (water tank); its biggest disadvantage is that in the severe cold weather in winter in the north, the antifreeze device will fail if there is a power failure If it is serious, it will even cause the coil to freeze and crack; normally installed water heaters are connected to the tap water pipe, and when the coil freezes and cracks, there will be water leakage; The user's home was soaked, causing serious property damage

It is not an antifreeze model, and the above-mentioned coil bursting and soaking will also occur in case of sudden severe cold weather
