Description

Technical Field

[0001] The utility model relates to the field of gas water heaters, in particular to a gas water heater capable of observing water flow rate. Background Art

[0002] At present, some household gas water heaters are equipped with water flow sensors, and the water flow rate is displayed through an operation interface. A pressurization function button is also provided on the operation interface. When the user finds that the water flow rate is too low during the use of the gas water heater, the user can activate the pressurization function to increase the water output.

[0003] However, when the gas water heater is initially used or after long-term use, the error between the data of the water flow sensor and the actual water flow rate is relatively large. The water flow rate displayed on the user interface often does not match the actual water flow rate, and it is easy to occur that the actual water flow rate cannot reach the starting water flow rate of the water heater, resulting in the water heater stopping working. Moreover, the user cannot observe the real-time water flow rate inside the water heater, and the user mistakenly believes that it is a problem of the water heater itself, which may lead to the user returning the goods or repairing it by mistake.

[0004] Therefore, there is an urgent need for a gas water heater capable of observing the water flow rate in real time. Summary of the Utility Model
