Description

Instant hot water outlet device
Technical Field
The invention relates to the technical field of domestic hot water circulation, in particular to an instant hot water outlet device.
Background
In the prior art, various domestic water heaters have a common problem in practical application, namely when a user opens the water heater to use hot water, the cold water reserved in a hot water pipeline leading from the water heater to a water using point must be discharged firstly, the hot water can flow out, the longer the hot water pipeline is, the more the cold water needs to be discharged when the hot water is used, the longer the consumed time is, the discomfort is inconvenient, and a large amount of water resources are wasted. To address this phenomenon, one of the solutions in the prior art is to connect in series a cold water pipe and a hot water pipe near the position of a mixed water valve at a certain water consumption point (usually at the position of a shower water consumption point) in a local water pipeline environment within the jurisdiction of a water heater, and to set a circulating pump device with a water flow sensing device on a pipeline near a cold water inlet of a water heater host (or on a hot water outlet) (or to place the circulating pump device in a water heater casing), so that when the circulating pump device is operated, water stored in the hot water pipe under the jurisdiction of the water heater can form a backflow circulation at the water consumption point connected in series and in parallel by means of the cold water pipeline, and is heated by the water heater and then conveyed back to the hot water pipeline, thereby heating the water stored in the hot water pipeline, and when a hot water tap of the shower water consumption point connected in series and in parallel is opened, hot water can be discharged quickly.
Because the main body of the circulating pump device under the prior art solution is arranged at a position far away from a water consumption point and close to a water heater or in a shell of the water heater, accurate temperature measurement of water stored in a hot water pipeline at the position of the water consumption point is difficult to realize, and when a user needs to use the instant hot water discharging function, the circulating pump device can be started only by one of the following three different forms of operation actions.
In the first mode, the operation time of the circulating pump device is preset. Therefore, the circulating pump device can automatically run in a certain time period or the same time period every day, but the inconvenience is that when a user opens the hot water faucet in the non-reserved set time, the user also needs to perform remote control opening or other manual starting actions and waits for the circulating device to heat the water stored in the pipeline for a certain time after starting the hot water faucet, otherwise, the hot water cannot flow out immediately when the hot water faucet is opened. Meanwhile, no matter whether a person prepares to use hot water in the water using area, the preheating process of water stored in the pipeline in the whole period of the circulating pump device can also cause unnecessary waste of energy.
The second starting mode is that before hot water is ready to be used, a user can remotely start the circulating pump device through the remote controller, but in practical application, because the distance, the wall and the like in different application environments shield the influence of communication signal factors, the situation that remote control operation is invalid often exists, and great inconvenience is brought to the user.
The third opening mode is that the user can manually open and close the hot water tap of a certain water using point in a certain time, and the action of discharging a small section of water stored in the pipeline is used for sending a water flow signal to a water flow switch in the circulating pump device, so that the circulating pump device is started to operate. However, in this way, the user needs to wait for the circulation pump device to operate for a certain time after starting the device, and then open the hot water tap to quickly discharge the hot water.
