Heater 1 under closed state, comes back to hot water storage tank 2.
When heat accumulation works, heated to completing the hot water that temperature declines after constant temperature works in hot water storage tank 2.Water pump 3 opens
It is dynamic, while the first valve 31 and the second valve 32 are opened, the 3rd valve 33 is closed.The hot water that temperature declines in hot water storage tank 2 exists
It under the drive of water pump 3, is flowed out from the water outlet of hot water storage tank 2, reaches the water intake end of water pump 3 by the second valve 32, and due to
The one-way conduction effect of second check valve 22, the hot water that the temperature declines can only enter water by water pump 3 and by heater 1
End, reheated in heater 1, then from the water outlet of heater 1 through piping again by the water intake end of hot water storage tank 2
Into hot water storage tank 2.
A kind of pipeline thermostat that the utility model embodiment 1 provides drives the hot water in hot water storage tank by water pump,
And hot water pipeline and cold water pipes are attached using the first check valve, are to enable hot water in systems in constant temperature work
It is cycled, is returned to after not carrying out heater heating up to warm hot water in hot water storage tank, the energy when constant temperature next time works
The temperature for enough reaching enough is cycled again, ensure that hot water pipeline in cold climates can also maintain certain temperature,
During hot water is cycled, water consumption is saved, while heater extends cold district heat without frequent starting
The service life of waterpipe and the service life of heater, have saved the consumption of water resource, and reduce the waste of the energy.
It is a kind of structure diagram for pipeline thermostat that the utility model embodiment 2 provides referring to Fig. 2.This practicality
The pipeline thermostat that new embodiment 2 provides adds water mixing valve 24 on the basis of embodiment 1 inside water heater 10.
The hot water water intake end of water mixing valve 24 connects the water outlet of hot water storage tank 2 by pipeline, and the cold water water intake end of water mixing valve 24 passes through pipe
Road connects the water outlet of water pump 3, and the water outlet of water mixing valve 24 connects water outlet 12 by pipeline.
With reference to Fig. 2, detailed retouch is carried out to the course of work of the pipeline thermostat of the offer of the utility model embodiment 2
It states.
It is user's hot-water supply during normal work.External cold water is imported water heater by cold water pipes 42 by water inlet 11,
First valve 31, the second valve 32, water mixing valve 24 and water pump 3 are turned off, and the 3rd valve 33 is opened, and cold water flows through the 3rd valve
33, heater 1 is entered by the water intake end of heater 1 and is heated, heater 1 is by the hot water become after cool water heating from water outlet
Output, enters hot water storage tank 2 by the water intake end of hot water storage tank 2 through piping and stores, and when user is needed with water, accumulation of heat water
The hot water stored in case 2 is exported from the water outlet of hot water storage tank 2, and water mixing valve 24 opens, introduce hot water from hot water storage tank 2 and
Cold water from the second valve 32, mixes water temperature to user's required temperature in water mixing valve 24, and warm water is by water mixing valve 24
Water outlet flow to water outlet 12, and into hot water pipeline 41 for users to use.
When constant temperature works, the temperature of hot water pipeline 42 is maintained.Temperature sensor 4 detects the pipeline temperature of hot water pipeline 42 first
Degree when the pipe temperature is less than preset temperature, starts water pump 3, and the first valve 31 is opened, the second valve the 32, the 3rd
Valve 33 and water mixing valve 24 are closed.In other embodiments, temperature sensor 4 can be used for inside detection hot water pipeline 42
Hot water water temperature when the hot water water temperature is less than preset temperature, carries out same operation, does not influence the beneficial of the utility model acquirement
Effect.Water pump 3 drives being flowed out up to warm water from the water outlet of hot water storage tank 2 in hot water storage tank 2, by the first valve 31, by
Water outlet 12 flows into hot water pipeline 41, is maintained the temperature of hot water pipeline 41, and enters cold water from the first check valve 21
Pipeline 42, cold water can not enter hot water pipeline 41 due to the one-way conduction effect of the first check valve 21 from cold water pipes 42, heat
Water passes through 22 He of the second check valve by entering water heater 10 by water inlet 11 after cold water pipes 42 under the drive of water pump 3
Water pump 3 by the heater 1 under being closed, comes back to hot water storage tank 2.
When heat accumulation works, heated to completing the hot water that temperature declines after constant temperature works in hot water storage tank 2.Water pump 3 opens
It is dynamic, while the second valve 32 is opened, the first valve 31, the 3rd valve 33 and water mixing valve 24 are closed.Temperature declines in hot water storage tank 2
Hot water under the drive of water pump 3, flowed out from the water outlet of hot water storage tank 2, enter water by what the second valve 32 reached water pump 3
End, and since the one-way conduction of the second check valve 22 acts on, the hot water that the temperature declines can only be by water pump 3 and by heater
1 water intake end is reheated in heater 1, then from the water outlet of heater 1 through piping again by hot water storage tank 2
Water intake end enter hot water storage tank 2.
A kind of pipeline thermostat that the utility model embodiment 2 provides drives the hot water in hot water storage tank by water pump,
And hot water pipeline and cold water pipes are attached using the first check valve, are to enable hot water in systems in constant temperature work
It is cycled, is returned to after not carrying out heater heating up to warm hot water in hot water storage tank, the energy when constant temperature next time works
The temperature for enough reaching enough is cycled again, ensure that hot water pipeline in cold climates can also maintain certain temperature,
During hot water is cycled, water consumption is saved, while heater extends cold district heat without frequent starting
The service life of waterpipe and the service life of heater, have saved the consumption of water resource, and reduce the waste of the energy.
During user's water, by water mixing valve by high-temperature-hot-water and cold water mix, in guarantee with water up to temperature while, improve making for hot water
With efficiency, the energy consumption to being heated with water has been saved.
The above is the preferred embodiment of the utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
