Integrated central water heating system

Abstract

The invention discloses an integrated central water heating system, which comprises a living water supply pipe, a heating component, a water inlet pipe, a water outlet pipe, a heat collector, master control equipment and a water supply pipeline, wherein the heating component, the water inlet pipe, the water outlet pipe, the heat collector and the master control equipment are arranged in a water heater and connected with the living water supply pipe; the heat collector is connected with the water inlet pipe and the water outlet pipe; the master control equipment is electrically connected with the heat collector; the water supply pipeline is used for a plurality of water consumption points and is connected outside the master control equipment; the peripheral water supply pipeline of the water consumption points is provided with a water mixing valve connected with the living water supply pipe, and the water outlet pipe of the heat collector respectively; a control device controls the communication between each pipeline and the closing of the pipelines in a time sharing way; a circulating water loop and a cold water branch pipe are mutually independent in a preheating mode and an anti-freezing mode; and a hot water conduit and a return water conduit are mutually independent in a bath mode. The integrated central water heating system not only can recycle water between a hot water outlet and a heating part of the water heater so as to save water, but also has the characteristics of instant water heating, multi-point and multi-temperature water supply, and intelligent anti-freezing property.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an integrated central hot water system. Background technique [0002] In recent years, my country's water resources have become increasingly tense, and the concept of water conservation has penetrated into all walks of life. However, in the water heater market, water heaters (such as water heaters above 16 liters) can realize multi-point water supply, and water points can be 2, 3 or even more. Many, its external piping system is more complicated, and there are many waterways. When the water heater is not working, the water in the external pipelines is cold water. In use, the cold water in these pipelines must be drained before hot water can be obtained. This process generally takes more than ten seconds. Therefore, there are two problems in the use of multi-point water supply for water heaters: one, the waste of water, gas and electricity; the cold water in the pipeline gen...

Problems solved by technology

Therefore, there are two problems in the use of multi-point water supply for water heaters: one, the waste of water, gas and electricity; the cold water in the pipeline generally cannot be used for bathing, and is generally discharged directly, resulting in waste of water resources; The road is long, and all the hot water stays in the pipeline, and the hot water will be cooled slowly in the natural state, and will be discharged before the next use. Therefore, the hot water is wasted, and the water is wasted , electricity or gas

Second, it is inconvenient; since the discharge of cold water in the pipeline generally takes more than ten seconds, it takes a long time to wait during use, making it uncomfortable and convenient to use

In order not to waste water resources, people try to store the cold water in the pipeline back. For example, the Chinese patent application number is 200610144034.3, the application date is 2006.11.24, and the name of the invention is a gas water heater. The return pipe is used to return and store this part of cold water, and then enter the heating device when the temperature is detected to be low. Although the purpose of recycling and eliminating waste is achieved, the invention is equipped with a water storage tank. When the user uses it, the water outlet pipe and the heating device The cold water between the devices is pumped to the water storage tank for storage, and then the cold water is heated for the user to use, so hot water cannot be hot immediately; limited by the volume of the water tank, this invention cannot achieve multi-point multi-temperature water supply; The water storage tank is not only easy to scale and shorten the service life of the equipment, but also the water temperature in the water tank is uneven, there is a certain temperature difference, even after heating the parts, the constant temperature cannot be reached, which affects the use effect
