An instant-on and instant-heating gas water heater circulation pipeline control system

Abstract

The invention discloses an instant heating gas water heater circulating pipeline control system. The system comprises a gas water heater body, a plurality of water consuming points, a hot water pipeline and a cold water pipeline. The cold water pipeline is divided into two paths A and B through a valve. The path A is connected with the gas water heater body to supply cold water to the gas water heater body. The path B is connected with the water consuming points to supply cold water to the water consuming points. The hot water pipeline is connected between the gas water heater body and the water consuming points to supply hot water to the water consuming points. The system is characterized in that an electronic control one-way valve is further arranged between the hot water pipeline at the farthest water consuming point and the path B of cold water pipeline; and when the electronic control one-way valve is turned on, water flows from the hot water pipeline to the path B of cold water pipeline. When the electronic control one-way valve is turned on, part of the cold water pipeline serves as a return water pipeline, and the instant heating function of the gas water heater is achieved. Fundamentally, the hot water pipeline and the cold water pipeline are relatively reliably independent, so that the problem that water heater self-starting caused by water utilization is thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of gas water heater control, in particular to an instant-on and instant-heat gas water heater circulation pipeline control system with WiFi function. Background technique [0002] At present, there are instant hot gas water heaters on the market. Although users can heat the water in the pipeline to the set temperature in advance, they need to manually turn on the instant heating or reservation function, and the long-term opening of the reservation function not only consumes a lot of electricity, Also can not reflect the high convenience of gas water heater. In addition, because the remote control method is limited by space distance and transmission power, with the rapid development of smart home technology and the high popularity of smart phones, the development of an instant hot gas water heater based on WiFi function will definitely be favored by the market. [0003] In addition, the existing instant-on g...

Problems solved by technology

[0002] At present, there are instant hot gas water heaters on the market. Although users can heat the water in the pipeline to the set temperature in advance, they need to manually turn on the instant heating or reservation function, and the long-term opening of the reservation function not only consumes a lot of electricity, Can not reflect the high convenience of gas water heaters

In addition, because the remote control method is limited by the space distance and transmission power, with the rapid development of smart home technology and the high popularity of smart phones, the development of a WiFi-based instant hot gas water heater will definitely be favored by the market

[0003] In addition, the existing instant-on gas water heaters generally need to install a special "return water pipe", and there is generally no return water pipe for the renovated house, and many users will not take the initiative to install the return water pipe even in the unfurnished house Therefore, the current sales of instant gas water heaters are not optimistic

Although there are occasional patent mentions of the "no return pipe" instant hot gas water heater, the hot water pipe and the cold water pipe are not relatively reliable and independent. It flows into the cold water pipe, and what is more serious is that when we use water at any water point, due to the change in pressure difference across the one-way valve, the water in the hot water pipe may flow into the cold water pipe through the one-way valve. When the amount is relatively large, it will cause the water heater to start automatically, and the closer the water point is to the one-way valve, the easier it will be to cause the water heater to start automatically

However, if the mechanical one-way valve commonly used in gas wall-hung boilers is used, the feasibility is not good due to the disadvantages of being greatly affected by water pressure fluctuations and poor sealing.
