Hot-water supplying system

Abstract

A hot water supply system comprises a hot water source which can continuously output the heated water flow; a water return pipeline, of which the front end communicates with a water outlet of the hot water source, the tail end communicates with a water inlet of the hot water source, and a group or more groups of water outlet valves are arranged thereon; a main control unit, which is provided with a temperature control part to monitor the temperature of the water flow in the water return pipeline and maintain the temperature at the state that is in line with the set water temperature by a user and a preset timing part; a pump which is arranged in the water return pipeline and is manipulated by the temperature control part of the main control unit to operate; a first temperature detector which can detect the temperature of the water flow at the tail end part of the water return pipeline; a second temperature detector which can detect the temperature of the hot water at the water outlet of the hot water source; and a plurality of groups of control units of using terminals which are provided with a control panel and a water temperature display device.

Description

technical field [0001] The invention relates to a hot water supply system, in particular to a hot water supply system capable of preheating the water flow of a water supply pipeline and monitoring the water temperature. Background technique [0002] Water heaters are mainly used to provide warm water for washing and bathing, and have become an indispensable device for families today. The more common types of water heaters are: gas water heaters, electric water heaters, and solar water heaters. Among them, gas water heaters have stable functions , equipment costs and energy costs are relatively low, so it is widely used in general households; gas water heaters are heated by natural gas combustion, but gas combustion will consume a large amount of oxygen and produce carbon dioxide. It will produce toxic gases such as carbon monoxide, so it is easy to cause hypoxia suffocation or carbon monoxide poisoning when used indoors. Newspapers and TV news often report on such incidents....

[0002] Water heaters are mainly used to provide warm water for washing and bathing, and have become an indispensable device for families today. The more common types of water heaters are: gas water heaters, electric water heaters, and solar water heaters. Among them, gas water heaters have stable functions , equipment costs and energy costs are relatively low, so it is widely used in general households; gas water heaters are heated by natural gas combustion, but gas combustion will consume a large amount of oxygen and produce carbon dioxide. It will produce toxic gases such as carbon monoxide, so it is easy to cause hypoxia suffocation or carbon monoxide poisoning when used indoors. Newspapers and TV news often report on such incidents. In addition, there are often cases of careless use or gas pipes. Road ruptures lead to gas leakage, so that the gas permeates the indoor space. When the ignition is used or electrical sparks will cause explosions or fire accidents, especially in winter or rainy seasons, people are used to closed doors and windows and indoor and outdoor air circulation. , it is more likely to cause the above-mentioned accidents. In summary, it can be seen that the gas water heater is not suitable for installation indoors; and in order to avoid the above-mentioned accidents, the gas water heater is usually installed on a ventilated balcony or used outdoors, so that the water heater is not connected to the water supply. The distance between the faucets is greatly increased, from a few meters to tens of meters, or even farther. Such an arrangement will cause a difference in the water supply temperature of the front and rear pipe sections during use, causing hot and cold water supply to fluctuate. In addition to the phenomenon, especially in the initial stage of water supply, it causes a lot of waste of water resources and inconvenience in use, for example: in the initial stage of hot water supply, the user turns on the faucet, the water heater ignites the gas to heat the water , It usually takes about ten to twenty seconds to wait for hot water to be used, so it is very inconvenient to use, and the cold water in the water supply pipeline will be discharged during this period, and these It is conservatively estimated that the amount of water that is not used in exile is at least 5 liters each time, and the average person wastes at least 1,500 liters of water per year. If the people in Taiwan are calculated for a whole year, at least 35 billion liters of water will be wasted for no reason. This result It not only increases the burden of personal water expenses, but also wastes a lot of water resources; the above-mentioned problems can be solved by installing hot water boilers or using high-power electric water heaters, but the installation of hot water boiler equipment is not expensive, which is not the case for ordinary families. However, the installation of high-power electric water heaters will not only lead to high electricity costs, but also need to update the power supply equipment to meet the high current operation required by the electric water heaters, which is extremely inconvenient
