Description

Human body induction type pipeline connecting device

Technical Field

The invention relates to the technical field of domestic hot water pipeline circulation, in particular to a human body induction type pipeline connecting device.

Background

In the prior art, various domestic water heaters have a common problem in practical application, namely, because each water consumption point has a certain distance with the domestic water heater, when a user opens a hot water tap of any water consumption point to use hot water of the water heater, cold water remained in a pipeline between the water consumption point and the water heater must be discharged firstly to flow out hot water, the longer the hot water pipeline is, the more cold water needs to be discharged when the hot water is used, the longer the consumed time is, inconvenience and discomfort are caused, and a large amount of water resources are wasted.

In the prior art, particularly in a water environment where a hot water circulating return pipe is not pre-buried during house decoration, the most common solution to solve the problem is to use a water circulating device in combination with a "cold and hot water pipe connection" in the prior art, in which a check valve and two three-way connections are provided (see fig. 7). The water circulating device is arranged on a cold water pipeline close to a cold water inlet of the water heater in a water using environment (the water circulating device can also be arranged in the water heater), a cold and hot water pipeline connecting piece in the prior art is used for connecting the cold and hot water pipelines in series at a certain water using point in the local water using environment, the position of a water using point faucet or a shower head farthest away from the water heater in the water using environment is usually selected as a mounting point of the cold and hot water pipeline connecting piece in the prior art (the connection method is shown in figure 7), in this way, the normal temperature water stored in the cold and hot water pipelines can be driven by the water circulation device to flow back to the cold water inlet of the water heater, and then is heated by the water heater and then is conveyed into the hot water pipeline communicated with the water consumption point direction of the 'cold and hot water pipeline connecting piece' in the prior art, a main circulation path for preheating the water stored in the pipes is formed in the local water environment (see fig. 8).

However, when the "cold and hot water pipe connecting piece" in the prior art is used in cooperation with the water circulating device, only a specific water point can be selected from a local water using environment with a plurality of water using points for installation, if the "cold and hot water pipe connecting piece" in the prior art is installed at a second or a plurality of water using points in the local water using environment, when the water circulating device works, water flow automatically flows to the water using point which is closest to the water heater and is provided with the "cold and hot water pipe connecting piece" in the prior art, and the position is always used as a water flow circulation turning point, so that the technical effect that each water using point can participate in circulation driven by the water circulating device cannot be realized.

However, in the local water pipeline environment governed by the domestic water heater, there is usually not only one water point, such as at least a kitchen sink, a wash stand of a toilet and a shower head in a shower area, and especially a larger-area residence may have more than two toilets, but the solution in the prior art can only install a "cold and hot water pipeline connector" in the prior art no matter how many water points exist in the water environment. For families with large living areas and even families with more than two bathroom bathing areas in duplex houses, under the existing solution, hot water can only be discharged immediately when a hot water tap with one water using point in a water environment is opened, and when other hot water taps with the water using points distributed on an upper line along a circulation trunk line are opened, a phenomenon that a section of cold water flows out first to discharge hot water still exists, the longer the distance of branch line pipelines is, the more cold water needs to be discharged when the branch line water using points open the hot water taps, and the longer the waiting time is.

The 'cold and hot water pipeline connecting piece' in the prior art can not block water flow when the temperature of water flowing through the connecting piece reaches a certain temperature, can not automatically sense whether a person enters a water using point area to prepare to use hot water in a water using environment with a plurality of water using points, and does not have the technical condition that each water using point participates in the circulating process driven by a water circulating device.
