Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Fig. 1 shows a block diagram of a water heater according to an embodiment of the present application. As shown in fig. 1, the water heater includes: a heating device 10, a bypass 20 and a control device 30.

The heating device 10 is used for heating the water flowing in the water inlet pipe 40 and delivering the heated water to the water outlet pipe 50. The structure of the heating apparatus 10 may be selected and adjusted according to the type of the water heater, and is not particularly limited herein. The heating device 10 may be a device for directly heating the water flowing into the water inlet pipe 40, or a device for heating the water flowing into the water inlet pipe 40 by heat exchange. For example, when the water heater is a gas water heater or a wall-hanging stove, the heating device 10 may include a heat exchanger and a burner.
The bypass pipe 20 is disposed between the inlet pipe 40 and the outlet pipe 50, and communicates with the inlet pipe 40 and the outlet pipe 50. The junction of the bypass pipe 20 and the outlet pipe 50 is provided with a first valve 21. The structure of the first valve 21 can be selected and adjusted as needed, and is not particularly limited herein. The first valve 21 has at least a first opening state and a second opening state, and the first opening state and the second opening state can be switched.
The first open state of the first valve 21 is: the first valve 21 communicates the outlet pipe 50 with the outlet valve of the water heater and does not communicate the outlet pipe 50 with the bypass pipe 20, so that the water in the outlet pipe 50 can flow out of the water heater for use by a user via the first valve 21 and the outlet valve without flowing into the bypass pipe 20.
The second open state of the first valve 21 is: the first valve 21 connects the outlet pipe 50 to the bypass pipe 20 and does not connect the outlet pipe 50 to the outlet valve of the water heater, so that the water in the outlet pipe 50 can flow into the bypass pipe 20 via the first valve 21 and flow back into the inlet pipe 40 via the bypass pipe 20 without flowing out of the water heater from the outlet of the water heater.
The water inlet pipe 40 is provided with a flow detection device 60, and the flow detection device 60 is used for detecting the water flow in the water inlet pipe 40. The water outlet pipe 50 is provided with a temperature detection device 70, and the temperature detection device 70 is used for detecting the temperature of the water in the water pipe 50.
The flow rate detection device 60 may be any device known in the art, and may be any device capable of detecting the flow rate of water. For example, the flow rate detection device 60 may employ a flow rate sensor. The temperature detection device 70 may be any device known in the art, and may detect the temperature of water. For example, the temperature detection device 70 may employ a temperature sensor or a thermocouple.
The control device 30 is electrically connected to the first valve 21, the flow rate detection device 60, and the temperature detection device 70. The control device 30 is configured to control the operation of the first valve 21 based on the detection results of the flow rate detection device 60 and the temperature detection device 70. The control device 30 can receive the flow detection result in the water inlet pipe 40 sent by the flow detection device 60. The control device 30 is also capable of receiving the water temperature detection result in the water outlet pipe 50 sent by the temperature detection device 70. The control device 30 controlling the actuation of the first valve 21 may comprise controlling different ports of the valve to communicate with or block different lines.
In one embodiment, a drive device 80 is provided on the bypass conduit 20. The driving device 80 is electrically connected to the control device 30, and the driving device 80 is used for controlling the flow direction of the water in the bypass pipe 20. The driving device 80 may be any device in the prior art, and the flow direction of water may be controlled.
In one example, the drive device 80 may be a water pump.
When the water heater of the present embodiment is in operation, the control device 30 controls the first valve 21, so that the water heated by the heating device 10 can flow out of the water heater through the water outlet pipe 50 and the water outlet valve. The water heated by the heating device 10 can flow into the bypass pipe 20 through the water outlet pipe 50 and flow back to the heating device 10 through the bypass pipe 20 and the water inlet pipe 40 to be heated again, so that the temperature of the water in the water outlet pipe 50 is increased, the water in the water outlet pipe 50 is ensured to flow out of the water heater after being preheated, and the water flowing out of the water heater for the first time is hot water.
FIG. 2 shows a flow chart of a water heater control method according to an embodiment of the application. As shown in fig. 2, the water heater control method includes:
s100: under the condition that the water outlet valve of the water heater is opened, the control device controls the heating device to be started according to the detection result of the flow detection device on the water inlet pipe, and controls the first valve on the bypass pipe to be switched from the first opening state to the second opening state.
The first opening state is that the first valve enables water in the water outlet pipe to flow out of the water heater through the water outlet valve, and the second opening state is that the first valve enables water in the water outlet pipe to flow back to the water inlet pipe through the bypass pipe.
The water outlet valve can be used for controlling a shower head of the water heater to discharge water when a user uses the water heater. The opening of the water outlet valve of the water heater can be understood as the opening process of the water outlet valve of the water heater and can also be understood as the moment when the water outlet valve of the water heater is completely opened.
The detection result of the flow detection device can be understood as that the flow detection device detects that water flows into the water inlet pipe and the water flow reaches the preset water flow required by the starting of the heating device. Controlling the heating means to be activated is understood to mean controlling the heating means to preheat and heat the water flowing in the inlet conduit.
In one example, the first valve default open state is a first open state.
In one example, the flow detection device may send a detection result to the control device when detecting that the water flow reaches a preset water flow, so that the control device controls the heating device to start and the first valve to switch the open state after receiving the detection result.
In another example, the control device obtains the detection result of the flow detection device in real time or at regular time, controls the heating device to start when the flow detection result is judged that the water flow in the water inlet pipe reaches the preset water flow, and controls the first valve to switch the opening state.
S200: the control device judges whether the water temperature reaches the threshold temperature according to the water temperature detection result in the water outlet pipe by the temperature detection device.
The threshold temperature may be understood as the temperature of the water in the outlet pipe reaching the temperature required for comfortable use by the user. For example, the threshold temperature may be 35-55 degrees. The threshold temperature may be equal to or less than a preset heating temperature of the heating device.
The control device can control the temperature detection device to detect the water temperature in the water outlet pipe in real time or in a timing mode.
S300: and under the condition that the water temperature reaches the threshold temperature, the control device controls the first valve to be switched from the second opening state to the first opening state.
The embodiment can realize that when the water heater is started, the water flowing out of the water outlet pipe can flow back to the heating device through the bypass pipe to be heated again until the water in the water outlet pipe reaches the threshold temperature and then automatically flows out of the water heater, so that the water flowing out of the water heater at first is hot water.
In one embodiment, as shown in fig. 3, after controlling the first valve on the bypass pipe to switch from the first open state to the second open state, the method further includes:
s400: the control device controls the drive device on the bypass pipe to be started, so that the drive device conveys the water from the water outlet pipe to the water inlet pipe through the bypass pipe.
In the embodiment, the driving device can provide power for the water in the bypass pipe, so that the water in the water outlet pipe can smoothly flow into the bypass pipe and flows back to the heating device through the bypass pipe to be heated again.
In one embodiment, as shown in fig. 4, the water heater control method further includes:
s500: the control device controls the drive device to be turned off in a case where the water temperature reaches a threshold temperature.
In one embodiment, as shown in fig. 5, the water heater control method further includes:
s600: under the condition that the water outlet valve is closed, the control device controls the heating device to be closed, controls the first valve to be switched from the first opening state to the second opening state, and controls the driving device on the bypass pipe to be started.
In the embodiment, the driving device can realize that the water remained in the water outlet pipe, the water inlet pipe and the heating device can still circularly flow in the water heater when the water inlet pipe and the water outlet valve are closed. Thereby ensuring that hot water can directly flow out of the water outlet pipe when the water outlet valve is opened again.
In one embodiment, as shown in fig. 6, the water heater control method further includes:
s700: the control device controls the driving device to close under the condition that the closing time of the water outlet valve is detected to exceed the threshold time.
The closing time can be selected and adjusted according to needs, and whether the user turns on the water heater again in a short time or not can be judged through the closing time. If the closing time exceeds the threshold time, the user does not have a use requirement in a short time, and at the moment, the driving device can be stopped to save energy, so that the water stored in the water heater is not heated circularly through the water outlet pipe, the bypass pipe, the water inlet pipe and the heating device.
