Preheating module and gas hot water equipment system using the preheating module

Abstract

The preheating module and the gas hot water equipment system adopting the preheating module. The present invention provides a preheating module, which is suitable for being attached to a gas hot water Cold water in the internal and external circulation pipelines of water equipment. The preheating module includes a water inlet pipe section which can be connected with the water inlet pipe of the gas hot water equipment, a water return pipe section connected with the water inlet pipe section, and a water pump arranged on one of the water inlet pipe section and the water return pipe section. Since the preheating module is used in conjunction with gas hot water equipment, it can realize instant heating with domestic hot water, thereby improving user experience. In addition, since the preheating module is set independently of the gas hot water equipment, the manufacturer can sell the gas hot water equipment separately, the preheating module can also be sold separately, or the system composed of the gas hot water equipment and the preheating module can be sold to meet the needs of different users. demand. In addition, when there is a demand for domestic hot water and the temperature of the imported cold water is high, the preheating module can also increase the flow of cold water through the water pump, so as to avoid the high temperature of the outlet water from the gas-fired hot water equipment and affect the user's use.

Description

technical field [0001] The invention relates to the field of household gas equipment, in particular to a preheating module suitable for gas hot water equipment. Background technique [0002] Gas hot water equipment usually includes gas water heaters and gas boilers. Taking a gas water heater as an example, a burner, a heat exchanger, and a pipeline system are usually arranged in it. The burner often includes several fire baffles arranged side by side, and each fire baffle has a gas-air mixing channel in which the gas and air can be mixed and delivered to the fire hole at the top of the fire baffle to burn in the combustion chamber and generate Heat, the generated heat can heat the water in the heat exchanger, and then the heated water can be exported through the pipeline system for the supply of domestic hot water for drinking and bathing. In addition to being used to provide domestic hot water, the gas boiler can also be connected to a radiator installed indoors to provid...

Problems solved by technology

However, compared with ordinary gas hot water equipment, these additional components for preheating will undoubtedly increase the manufacturing cost of the entire equipment and increase the selling price accordingly

However, not all users will need the warm-up function
