In the embodiment of the present invention, as shown in fig. 4 to 8, the water heater 100 system includes a gas water heater 100, a tap water pipe 200, a hot water pipe 300, a water returning device 400, a water pump 500 and a controller 600. The gas water heater 100 comprises a water inlet pipe 110 and a water outlet pipe 120, and an electric control valve 700 is arranged on the water inlet pipe 110 and/or the water outlet pipe 120. The tap water pipe 200 is communicated with the water inlet pipe 110; the hot water pipe 300 is communicated with the outlet pipe 120. The water return device 400 is provided with a first interface and a second interface, the first interface is communicated with the hot water pipe 300, the second interface is communicated with the tap water pipe 200, and the first interface is communicated with the second interface in a one-way mode on the water return device 400; a preheating circulation loop is formed among the water outlet pipe 120, the hot water pipe 300, the water returning device 400, the tap water pipe 200 and the water inlet pipe 110. The water pump 500 is arranged in the preheating circulation loop; the controller 600 is electrically connected to the water pump 500 and the electric control valve 700.
In the present embodiment, the inlet pipe 110 of the gas water heater 100 is communicated with the tap water pipe 200, and the outlet pipe 120 of the gas water heater 100 is communicated with the hot water pipe 300. The electrically controlled valve 700 is electrically connected to the controller 600. The electric control valve 700 may be specifically a water solenoid valve, a water proportional valve, an electric valve, a water switching valve, etc., and only needs to be able to control the on/off of the pipe where the electric control valve is located through the controller 600. By arranging the electric control valves 700 on both the water inlet pipe 110 and the water outlet pipe 120, in actual use, the waterway can be cut off only by controlling one of the electric control valves 700 to be closed. By arranging the two electric control valves 700, when one electric control valve 700 fails, the other electric control valve 700 can work, so that the operation stability of the water heater 100 system is ensured. Generally, only one electrically controlled valve 700 may be provided on the inlet pipe 110 or the outlet pipe 120 of the gas water heater 100. Preferably, the electric control valve 700 is disposed on the water outlet pipe 120 of the gas water heater 100, so that the electric control valve 700 has the best water stopping effect by utilizing the characteristics of the electric control valve 700 and the pipeline inertia characteristics, and air does not exist in the heat exchanger to affect the use of the gas water heater 100.
The electric control valve 700 is arranged on the water inlet pipe 110 and/or the water outlet pipe 120 of the gas water heater 100, so that the gas water heater 100 has the function of small start-stop temperature fluctuation. Specifically, the controller 600 obtains a water re-discharging signal to control the electronic control valve 700 to close; controlling an igniter of the gas water heater 100 to ignite a burner of the gas water heater 100; the ignition of the burner is determined and the electronically controlled valve 700 is controlled to open. In an embodiment, as shown in fig. 4 and 5, a water inlet detector 900 is disposed on the water inlet pipe 110 of the gas water heater 100, the water inlet detector 900 is electrically connected to the controller 600, and the controller 600 is configured to control the opening or closing of the electronic control valve 700 according to a water inlet signal of the water inlet detector 900. Therefore, the water inlet detector 900 on the water inlet pipe 110 of the gas water heater 100 can be directly used for obtaining the secondary water outlet signal, other structures are not needed to be additionally arranged, the structure is simple, and the judgment is accurate. The water inlet detector 900 may be a water pressure sensor or a water flow sensor. In other embodiments, the re-exiting signal may also be sent by a sensor at the mixing valve at the user's exiting end.
After the user closes the water, the water heater 100 enters a post-cleaning stage and finally enters a standby stage, the fan stops when the water heater is in standby, the burner is flamed out, and the air inlet valve assembly is closed. After the water outlet signal is obtained again, the controller 600 controls the electric control valve 700 to close, the water path is cut off, meanwhile, the fan is started to clean the burner, then the igniter is controlled to ignite, and the valve body of the air inlet valve assembly is opened, so that the burner is ignited.
When the preheating function of the gas water heater 100 is turned on, the preheated water is driven by the water pump 500 to circulate in the preheating circulation loop, thereby realizing the preheating function. The water pump 500 may be specifically disposed on the water inlet pipe 110 of the gas water heater 100. In this way, the water pump 500 not only can drive the preheated water to circulate in the preheating circulation loop, but also can drive the water in the tap water pipe 200 to enter the gas water heater 100 when the water pressure is insufficient.
Referring to fig. 3, when the return water temperature at the water inlet end of the water inlet pipe 110 of the gas water heater 100 reaches a first preset temperature, it may be determined that the heated water reaches the water inlet end of the water heater 100, and then the gas water heater 100 may be controlled to stop preheating, and the time from the first start of the water heater 100 to the stop of preheating of the water heater 100, that is, the first preheating time of the water heater 100, may be obtained.
Wherein, the circulation preheating time can just obtain hot water from the gondola water faucet when the user opens the muddy water valve of water end. That is, when the gas water heater 100 starts the preheating function again, if the preheating time of the gas water heater 100 is shorter than the cycle preheating time, the water at the shower head is still cold water when the user opens the water mixing valve at the water using end; if the gas water heater 100 is preheated for a time period longer than the cycle preheating time, excess water enters the tap water line 200. It should be understood that the first preheating time may substantially include the time that the heated water flows through the hot water pipe 300 and the tap water pipe 200, and thus, the time that the heated water flows through the hot water pipe 300 may be obtained according to the lengths of the hot water pipe 300 and the tap water pipe 200.
Because the temperature of the water heated firstly is reduced in the pipeline, when the circulating preheating time of the water heater 100 is calculated, the circulating preheating time of the water heater 100 can be corrected according to the preset circulating compensation time, so that the comfort of water utilization can be further improved. The sum of the time that the heated water flows through the hot water pipe 300 and the preset circulation compensation time can be used as the circulation preheating time of the water heater 100.
In one embodiment of the present invention, the lengths of the hot water pipe 300 and the tap water pipe 200 are substantially the same, so that the time that the heated water flows through the hot water pipe 300 is about half of the first preheating time. That is, in one embodiment of the present invention, the cycle warm-up time of the water heater 100 can be calculated according to the following formula:
T＝T1/2+T0
wherein, T is the cycle preheating time of the water heater 100, T1 is the first preheating time, and T0 is the preset cycle compensation time.
In one embodiment of the present invention, the preset cyclic compensation time T0 may be 0-60 seconds.
The utility model discloses an in other embodiments, still can open the preheating function for the first time at water heater 100, detect the temperature of water end, send to water heater 100 through the temperature with the water end for when the temperature of water end reaches predetermined temperature, control water heater 100 stops preheating, thereby can be directly with the first preheating time of water heater 100 as the time that the water flow after the heating passed through hot-water line 300 way.
When the preheating function of the water heater 100 is turned on again, the heating device and the water pump 500 may be turned on at the same time, and the heating device and the water pump 500 may be turned off after the circulation preheating time, so that the hot water just reaches the water using end.
The utility model discloses water heater 100 system is through being equipped with automatically controlled valve 700 on inlet tube 110 and/or outlet pipe 120 of gas heater 100, and controller 600 is connected with the solenoid valve electricity. Thus, when the water heater 100 system is turned off for the previous water outlet and turned off for the next water outlet, the electromagnetic valve is controlled to be closed, and after the igniter of the gas water heater 100 ignites the burner of the gas water heater 100, the electronic control valve 700 is controlled to be opened. Therefore, cold water can be prevented from entering the hot water pipe 300 before the gas water heater 100 is ignited again, the reignition temperature fluctuation of the gas water heater 100 is small, and the use experience of a user is greatly improved. And the first interface of the water returning device 400 is communicated with the hot water pipe 300, the second interface is communicated with the tap water pipe 200, the water pump 500 is arranged on a preheating circulation loop formed by the water outlet pipe 120, the hot water pipe 300, the water returning device 400, the tap water pipe 200 and the water inlet pipe 110, and the controller 600 is electrically connected with the water pump 500. The water heater 100 system has a preheating function and can realize instant heating when the water heater is started with zero cold water. Meanwhile, the preheating function of the water heater 100 system can adopt a half-pipe water preheating technology, namely the water heater 100 system can automatically acquire proper preheating time and can conveniently and quickly preheat the water heater 100 according to the acquired preheating time, so that heating of unnecessary pipelines can be reduced. Half pipe water preheats the foretell function that opens and stops temperature fluctuation little of technology collocation, promptly preheats the function at the user and opens the back, when needing boiling water to use in the short time, can guarantee to open temperature fluctuation minimum again, realizes that zero cold water opens promptly and heats promptly, and the temperature fluctuation is little when the user closes water and opens again for user's shower is experienced and is promoted greatly. And the zero-cold water product is more energy-saving, and the best zero-cold water effect is achieved by using the least preheating time and the optimal preheating gas consumption. In addition, only through setting up automatically controlled valve 700, alright realize that the short time opens and stops that the temperature fluctuation is little, experience good effect, compare in the buffer tank through the water pitcher model, greatly reduced overall cost, and make that system is small, installation and occupation space are little.
In one embodiment, as shown in fig. 8, the water returning device 400 is an H-valve 410, a first inlet of the H-valve 410 is a first interface, and a second inlet of the H-valve 410 is a second interface.
In the present embodiment, the H-valve 410 is electrically connected to the controller 600. The H-valve 410 may be connected to the hot water pipe 300 and the end of the water pipe 200 away from the gas water heater 100. By arranging the H-valve 410, the first inlet of the H-valve 410 is a first interface and is connected with the hot water pipe 300, and the second inlet is a second interface and is connected with the tap water pipe 200. The controller 600 can control the H-valve 410 to conduct from the first inlet to the second inlet in one way, and can also control the H-valve 410 to stop water from flowing to the user side. So, when needs use half tub of preheating function, only need to make first entry to second entry unidirectional flux, alright realize half tub of water preheating. The function of preheating the half-pipe water can be realized only by arranging the H valve 410, and the water preheating device is simple in structure, convenient to realize and easy to control.
In another embodiment, referring to fig. 6 and 7, the water returning device 400 includes a water returning pipe 430 and a check valve 420 disposed on the water returning pipe 430, wherein one end of the water returning pipe 430 is connected to the hot water pipe 300, and the other end of the water returning pipe 430 is connected to the tap water pipe 200.
In the present embodiment, the hot water pipe 300 is connected to the tap water pipe 200 through the water return pipe 430, and the check valve 420 is connected to the water return pipe 430 in series, so that the check valve 420 is communicated from the hot water pipe 300 to the tap water pipe 200 in one direction. The water return mode of the water return pipe 430 and the one-way valve 420 is simple in structure, low in cost and easy to achieve. It can be understood that when the water heater 100 system is in the preheating function, the water mixing valve at the user end is controlled to be closed to prevent the water from flowing out, so that the air flow of the hot water pipe 300 flows into the tap water pipe 200 to circulate, thereby realizing the preheating.
In one embodiment, as shown in fig. 6, one end of the water return pipe 430 is connected to one end of the hot water pipe 300 away from the gas water heater 100, and the other end of the water return pipe 430 is connected to one end of the water supply pipe 200 away from the gas water heater 100. Thus, the length of the water return pipe 430 can be greatly shortened, the tap water pipe 200 is fully utilized, and the pipeline structure is simplified, so that the structure of the whole water heater 100 system is simpler. At this time, in order to increase the service life of the water pipe 200, the same high temperature resistant material as that of the hot water pipe 300 may be used as the water pipe 200.
In another embodiment, as shown in fig. 7, one end of the water return pipe 430 is connected to one end of the hot water pipe 300 away from the gas water heater 100, and the other end of the water return pipe 430 is connected to one end of the water supply pipe 200 close to the gas water heater 100. It is understood that since the tap water pipe 200 is generally supplied with only cold water, the hot water pipe 300 is supplied with hot water, and thus the tap water pipe 200 and the hot water pipe 300 are made of different materials. The hot water pipe 300 is made of a high temperature resistant material, and the water pipe 200 is made of a common material, for example, if hot water passes through the water pipe 200 made of the common material for a long time, the aging and damage of the water pipe 200 are easily accelerated. Therefore, by additionally providing the water return pipe 430 to be connected to one end of the tap water pipe 200 close to the gas water heater 100, the tap water pipe 200 is prevented from being used in a large area in a preheating cycle, so that the service life of the tap water pipe 200 is prolonged, and the operation stability of the system is improved. To further improve the system stability, the return pipe 430 may use the same high temperature resistant material as the hot water pipe 300.
In an embodiment, referring to fig. 4 and 5, the water heater 100 further includes a temperature detector 800 electrically connected to the controller 600, the temperature detector 800 is disposed in the preheating circulation loop for detecting a return water temperature of the gas water heater 100, and the controller 600 is configured to control a circulation preheating time of the gas water heater 100 according to the return water temperature.
In the present embodiment, by detecting the return water temperature of the water inlet end of the gas water heater 100, it can be determined when the heated water reaches the water inlet end of the water heater 100. The return water temperature is detected by providing a temperature detector 800. When the return water temperature of the water inlet end of the water inlet pipe 110 of the gas water heater 100 reaches the first preset temperature, it can be determined that the heated water reaches the water inlet end of the water heater 100, and then the gas water heater 100 can be controlled to stop preheating, and the time from the first opening of the water heater 100 to the stop of preheating of the water heater 100, that is, the first preheating time of the water heater 100, is obtained. In order to make the return water temperature detected by the temperature detector 800 more accurate, it is preferable that the temperature detector 800 is disposed on the water inlet pipe 110 of the gas water heater 100 and is used for detecting the return water temperature of the water inlet pipe 110 of the gas water heater 100.
As shown in fig. 1 to fig. 3, the present invention further provides a control method of the gas water heater 100 system, so as to control the gas water heater 100 system in the above embodiment.
As shown in fig. n, the control method of the water heater 100 system according to the embodiment of the present invention includes the following steps:
and step S1, acquiring a water outlet signal again, and controlling the electronic control valve 700 to close.
The water re-outlet signal here means that the hot water of the previous water heater 100 system has reached the water outlet end of the user, that is, the user has used the superheated water, or the water heater 100 system has been subjected to the preheating cycle; therefore, when the water mixing valve at the water outlet end of the user is opened again, a water outlet signal is sent again. The re-water-outlet signal may be directly sent to the controller 600 by a sensor at the water mixing valve at the water outlet end of the user, or may be a water inlet signal of the water inlet detector 900 of the gas water heater 100, or a water flow sensor sending a re-water-outlet signal. When the controller 600 acquires the water re-outlet signal, the electronic control valve 700 is controlled to be closed, and at this time, water inflow in the gas water heater 100 is stopped.
In step S2, the igniter of the gas water heater 100 is controlled to ignite the burner of the gas water heater 100.
When the electric control valve 700 is closed, the igniter of the gas water heater 100 is controlled to ignite the burner of the gas water heater 100, that is, the burner is ignited. Thus, when the user needs to discharge water again, the water path is cut off first, and the ignition of the gas water heater 100 is waited. During the period between the acquisition of the re-water-outlet signal and before ignition, cold water continuously flows in, so that the cold water reaches the water outlet pipe 120 or the hot water pipe 300 of the gas water heater 100 before the ignition of the gas water heater 100, and thus the water temperature fluctuation is large when the user uses the water heater again, and the user experience is poor. And by closing the water way before the gas water heater 100 is ignited, cold water can be effectively prevented from flowing into the water outlet pipe 120 or the hot water pipe 300 of the gas water heater 100, so that the water temperature fluctuation is small when the user boils water again, and the use experience of the user is improved.
In step S3, the ignition of the burner is determined, and the electronic control valve 700 is controlled to open.
Wherein confirmation of burner ignition may be sensed by a temperature sensor or other sensing device. When the controller 600 receives the signal of the burner ignition, the electronic control valve 700 is controlled to be opened. It is understood that the electric control valve 700 may be controlled to be opened after a preset time after the burner is ignited, or the electric control valve 700 may be opened at the same time as the burner is ignited. In order to save gas, the electrically controlled valve 700 may be opened at the same time as the burner is ignited.
