The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the central hot-water heating system of a kind of integrated form of the present utility model, comprise water heater 1, living water pipe 2, the water inlet pipe 3 of water heater 1 inside that is connected with living water pipe 2, outlet pipe 4, connection is advanced, the heat collector 5 of outlet pipe, combustion chamber 6, the air inlet pipe 61 that connects combustion chamber 6, master control equipment 51 and outside several supply channels 8 that are connected thereof with heat collector 5 electrical connections with water spot 7, be provided with switch 9 with water spot, be provided with the mixed water valve 10 that connects living water pipe 2 and heat collector outlet pipe 4 respectively with the peripheral supply channel of water spot, water heater inside is provided with return pipe 11 and connected backwater joint 12, temperature detection device 13 and the water cycle power device 14 that is equipped with the power control that is electrically connected with master control equipment are installed on the return pipe 11, the other end of this water cycle power device 14 connects water inlet pipe 3, backwater joint 12 be externally connected to water return pipeline 15, the other end of this water return pipeline 15 is communicated with heat collector outlet pipe 4 by check valve 16.Be connected by triple valve 17 between water inlet pipe 3 and the return pipe 11, water supply connector 18, water proportioning valve 19, inflow temperature probe 20, check valve 21, common water valve 22 are installed on the water inlet pipe 3 successively, the check valve 21 of water inlet pipe 3 and the water cycle power device 14 of return pipe 11 are connected on the port of triple valve 17, and the another port of triple valve 17 is connected with common water valve 22.Water cycle power device 14 adopts water circulating pump, and the power-supply controller of electric of water circulating pump is electrically connected with master control equipment, and master control equipment 51 is provided with the preheating switch of control circuit break-make.Antifreeze temp probe 23 is installed on the heat collector 5 of water heater inside, and outlet pipe 4 is provided with leaving water temperature probe 24 and relief valve 25, and coolant-temperature gage probe 24 connects master control equipment.When hydraulic pressure was too high in system, relief valve 25 was opened pressure release automatically, and protection pipeline and main frame are not damaged.Establishing water flow sensing unit on the water proportioning valve 19 is electrically connected with master control equipment, control water cycle power device power circuit break-make, when have on the water proportioning valve 19 current by the time water flow sensing unit signal is mail to control appliance, disconnect the power supply circuits of water circulating pump, this water proportioning valve singly can not detect the size that has or not water-flow signal and discharge, can also automatically regulate aperture, control discharge size is for the analytical calculation of master controller provides water-flow signal.In several seconds, the water proportioning valve can be transferred to aperture less state, turns discharge down after lighting a fire successfully, water supply is comparatively fast reached temperature is set, and realizes fast constant temperature.
Wherein, be embedded with the control instruction of preheating mode, bathing pattern and antifreeze pattern in the master control equipment, the three large model courses of work are as follows:
One, preheating mode:
Under " preheating " function on prerequisite, if return water temperature probe detects water temperature≤34 ℃, then water circulating pump starts, flow valve detects and produces circulating water flow and discharge 〉=3.5L/min in the system, water heater igniting this moment is that the target temperature ratio is burnt with 42 ℃, and system water is carried out preheating; When return water temperature 〉=40 that return water temperature probe detects ℃, the water heater burning stops, the water circulating pump 3min that remains in operation.If return water temperature probe detects water temperature≤34 ℃, then water heater is ignition once more in 3min, and water temperature all 〉=40 ℃ in system's water pipe.
As long as " preheating " function is opened, electricity, gas all possess, and system will continue to detect water temperature so, to judge whether the needing burning heating, therefore system water temperature are maintained certain scope, satisfy the user and use at any time.
Two, bathing pattern
The bathing pattern is identical with the process of common water heater work heat supply water, and the hot water of temperature constant is provided to provide by the temperature of user's setting.
In three kinds of mode of operations, the bathing mode prioritization, promptly as long as the water proportioning valve detects current (have the user at water this moment), preheat function or antifreeze function must be ended or be under an embargo so.Water finishes back (the water proportioning valve detects less than current), and water circulating pump will start, and running 30s produces recirculated water, in 30s if return water temperature is popped one's head in detection water temperature≤34 ℃, then water heater is ignition once more, water temperature all 〉=40 ℃ in system's water pipe.
Three, antifreeze pattern
When leaving water temperature probe or return water temperature probe detected temperature≤7 ℃ or antifreeze temp probe and detect temperature≤5 ℃, antifreeze pattern started, i.e. water circulating pump running produces recirculated water, the water heater ignition, and system water heats up gradually; The temperature that is detected when return water temperature probe is during greater than 〉=20 ℃, antifreeze stopping.
Only one of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing; be not to limit to the utility model with this; under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
