Gas equipment for heating running water

Abstract

The invention discloses gas equipment for heating running water. The gas equipment comprises a water source and an expansion tank; the expansion tank is connected with the water source through a pipeline, and a water refilling valve and a water flow sensor are sequentially arranged on the pipeline for connecting the expansion tank and the water source, and the water refilling valve is controlled by a low-level sensor; the low-level sensor detects information of internal water level of the expansion tank, and has a threshold value H, and the refilling valve is turned on when the information ofwater level is lower than the threshold; the expansion water tank is connected with a heating cavity, a magnetic filter is arranged on a connecting pipe between the expansion tank and the heating cavity, a heat exchanger is arranged at the bottom of the heating cavity, and the heating cavity is connected with a water outlet unit; an SCR voltage regulating module is arranged in the heat exchanger,the heat exchanger is connected with a micro-computer master controller through an SCR contact-less relay, the micro-computer master controller detects temperature information of the heating cavity through a temperature detector, and an information input end of the micro-computer master controller refers to a temperature regulating button, and the SCR contact-less relay realizes on or off betweenthe heat exchanger and micro-computer master controller by regulating output voltage value.

Description

technical field [0001] The invention relates to a water heater, in particular to gas equipment for heating tap water. Background technique [0002] Energy saving and emission reduction is the development direction advocated by the state, and products with less energy consumption will be a direction of future development. As low energy consumption products, solar water heaters and air energy water heaters have a good momentum of development. However, due to some limitations of the product itself, the product has certain limitations in meeting the needs of consumers, so comprehensive energy utilization has become another direction for the development of water heaters. Water heater evaluation network believes that solar water heaters and air energy water heaters, as new energy products, are showing a strong momentum of development. Because of their unique performance, the two categories are rapidly expanding the market and have a strong response among consumers. [0003] In t...

Problems solved by technology

[0006] The technical problem to be solved by this invention is that the traditional water heater is directly connected to the water pipe, so that the water pressure will always generate pressure on the pipe interface when it is not used for a long time, which will cause the water inlet pipe of the water heater to be easily damaged, and the water after the water heater is heated It is mostly used for daily washing water. Although it will not be drunk directly, it will also enter the mouth and close to the skin. The water quality cannot be detected, and the harm to users is increasing. The traditional water heater does not have any alarm device, no matter the voltage of the electric water heater Excess, or natural gas leakage of gas water heaters, will cause damage to the safety of indoor personnel, so we need a safer water heater, the purpose is to provide gas equipment for heating tap water, to solve the above problems
