Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.
As shown in fig. 1 to 3, this embodiment provides a water heater system, which includes a heat exchanger 1, a water inlet pipe 2, a water outlet pipe 3, a cold water pipe 4, a hot water pipe 5, and a plurality of water consumption points 6, wherein one end of the water inlet pipe 2 is connected to a water inlet end of the heat exchanger 1, the other end is connected to the plurality of water consumption points 6 through the cold water pipe 4, one end of the water outlet pipe 3 is connected to a water outlet end of the heat exchanger 1, the other end is connected to the plurality of water consumption points 6 through the hot water pipe 5, a circulation pump 11 connected to the water inlet pipe 2 is disposed on the heat exchanger 1, the water heater system further includes a circulation water path 7, a solenoid valve 8, a controller, and a pressure switch 9, wherein the circulation water path 7 is disposed between the hot water pipe 5 and the cold water pipe 4 at the farthest water consumption point 6, the solenoid valve 8 is disposed in series on the circulation, the pressure switch 9 is used for detecting whether the cold water inlet of the farthest water using point 6 is opened or not and feeding back the detection result to the controller, and the controller controls the electromagnetic valve 8 to act according to the fed-back signal so as to switch the circulating water circuit 7.
The water heater of this embodiment, its simple structure can effectively avoid the water heater to take place the condition of muddy water. The water heater of this embodiment mainly controls the circulation water route of water heater through pressure switch 9 and solenoid valve 8 to replaced the circulation water route that ordinary water heater was used commonly and is equipped with the check valve control water heater in series on the circulation water route, and then effectively solved the pain point of zero cold water heater muddy water, practiced thrift the unnecessary consumption of gas.
In the present embodiment, the water consumption point 6 in the present embodiment includes a plurality of water consumption points 6, which are a far-end water consumption point 6 at the rightmost position in fig. 1 and the farthest distance from the water heater 1, and the circulation water path 7 is disposed between the hot water pipe 5 and the cold water pipe 4 of the water consumption point 10 to open or close the circulation water path 7, so that the water heater constitutes a closed circulation water path system through the heat exchanger 1, the water inlet pipe 2, the water outlet pipe 3, the cold water pipe 4, the hot water pipe 5, the circulation water path 7, and the circulation pump 11. In this embodiment, the water heater is in the zero cold water mode, and the solenoid valve 8 is opened simultaneously in the work of circulating pump 11, and the water in the hot water pipe 5 flows through the inlet tube 2 after flowing through the circulation water route 7 and the cold water pipe 4 in proper order and flows to the heat exchanger 1 inside to heat water again. When the farthest water consumption point 6 independently uses cold water, the pressure switch 9 detects that the cold water inlet of the farthest water consumption point 6 is opened and feeds back the detection result to the controller, the controller controls the electromagnetic valve 8 to close the circulating water path 7 according to the fed-back signal, so that water in the hot water pipe 5 cannot flow to the cold water pipe 4 through the circulating water path 8, the mixed water condition that hot water flows to the cold water pipe 4 from the hot water pipe 5 and flows out through the water consumption point 6 cannot occur, unnecessary waste consumption of fuel gas can be avoided, and industrial pain points are solved.
Furthermore, the water consumption point 6 is provided with a cold water valve connected with the cold water pipe 4, and the structure is simple and compact.
Preferably, the open-close state of the cold water valve and the open-close state of the electromagnetic valve 8 have opposite relation, and the design is reasonable and ingenious.
Specifically, the pressure switch 9 is disposed between the intersection of the circulation water path 7 and the cold water pipe 4 and the cold water valve of the farthest water consumption point 6, which further improves the reliability of the pressure switch detection.
In particular, the pressure switch 9 is a high-voltage switch, which is reasonably designed and can further improve the detection accuracy of the pressure switch.
In this embodiment, a cold water valve connected to the cold water pipe 4 is disposed at the farthest water point 6, the pressure switch 9 is used to determine whether the cold water inlet of the farthest water point 6 is opened by detecting the open/close state of the cold water valve, and the pressure switch 9 can more accurately detect whether the cold water inlet of the farthest water point 6 is opened by using a high-pressure switch, but is not limited to the high-pressure switch, and may also be a low-pressure switch, and of course, other more suitable pressure switches may be selected according to actual needs. In this embodiment, the open-close state of the cold water valve and the open-close state of the electromagnetic valve 8 have an inverse relationship, that is, when the pressure switch 9 detects that the cold water valve is in the open state, it is determined that the cold water valve is at a low pressure and the electromagnetic valve 8 is closed; when the pressure switch 9 detects that the cold water valve is in a closed state, the cold water valve is judged to be in a high pressure state, and the electromagnetic valve 8 is opened.
As shown in fig. 3, in the initial state of the water heater, the cold water valve of the farthest water using point 6 is in a closed state, the pressure switch 9 detects a high pressure, and the electromagnetic valve 9 is opened at the same time, so that the hot water in the hot water pipe 5 can reenter the water heater 1 for heating through the circulating water path 7, the cold water pipe 4 and the water inlet pipe 2 under the action of the circulating pump 11. When a user opens the cold water valve alone to use cold water, the pressure switch 9 detects that the cold water inlet of the farthest water consumption point 6 is opened, namely the pressure switch 9 detects that the pressure is low, at the moment, the controller closes the electromagnetic valve 8 according to a signal fed back by the pressure switch 9, so that water in the hot water pipe 5 cannot flow to the cold water pipe 4 through the circulating water channel 7, and the mixed water condition that hot water flows to the cold water pipe 4 from the hot water pipe 5 and flows out through the water consumption point 6 cannot occur.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
