In some embodiments, the gas water heater may further comprise a utility water tank 30, a utility water outlet pipe 31, a utility water outlet valve 32, a first detection device 33, and a control circuit 40.
The service water tank 30 may be disposed in the installation room of the housing 10 for pre-storing hot water, and its volume may be set between 2L and 5L (e.g., 2L, 3L, 5L, etc.).
The service water outlet pipe 31 is connected to the outlet of the service water tank 30 to draw out hot water. The temporary water outlet valve 32 is arranged on the temporary water outlet pipe 31.
The first detection device 33 is used for acquiring a water signal of the water usage end 4 connected with the temporary water outlet pipe 31. The control circuit 40 is connected to the service outlet valve 32 and the first detecting device 33, so as to control the service outlet valve 32 to be opened when receiving the water signal, and thus, the service water tank 30 is used for supplying the pre-stored hot water to the service water end 4.
The first detection device 33 may be a pressure sensor, and the temporary water outlet valve 32 may be a solenoid valve. The pressure sensor is arranged on the temporary water outlet pipe 31 and is positioned at the position behind the temporary water outlet valve 32, when the user opens the water end 4, the pressure behind the temporary water outlet valve 32 drops, when the pressure behind the temporary water outlet valve 32 is smaller than a preset value, the pressure sensor can send a water signal to the control circuit 40, and the control circuit 40 can control the temporary water outlet valve 32 to be opened after receiving the water signal.
One end of the temporary water outlet pipe 31 is connected to the outlet of the temporary water tank 30, the other end of the temporary water outlet pipe is connectable to the hot water main pipe 3, and when the temporary water outlet valve 32 is controlled to be opened by the control circuit 40, hot water pre-stored in the temporary water tank 30 is discharged to the hot water main pipe 3 through the temporary water outlet pipe 31, and then the water end 4 is discharged through the hot water main pipe 3, so that a user can quickly use the hot water.
That is, when the user opens the water use end 4, the gas water heater can supply water to the water use end 4 by using the hot water stored in advance in the temporary water tank 30, and the cold water is not heated by using the gas, so that the user can quickly use the hot water, and the frequent start and stop of the gas water heater caused by the short-time water use of the user can be avoided.
In some embodiments, the gas water heater may further include a water inlet valve 26 and a second detection device 34. A water inlet valve 26 is provided to the inlet pipe 22. The second detecting device 34 is connected to the control circuit 40 for acquiring an extended water signal of the water end 4 connected to the water outlet pipe 24. The control circuit 40 is also connected to the inlet valve 26, and when the control circuit 40 receives the extended water signal, it controls the temporary outlet valve 32 to be closed, and the inlet valve 26 to be opened, so that the water heated by the heating device 20 is delivered to the water end 4.
The water inlet valve 26 may be embodied as a solenoid valve and the second detection device 34 may be capable of acquiring an extended water signal from the water use end 4 that may be indicative of a user's need for a large volume of hot water. When the control circuit 40 receives this signal, it controls the closing of the service outlet valve 32 and the opening of the inlet valve 26, i.e. the switching of the way in which hot water is supplied, and the way in which cold water is heated by the gas.
Further, the second detecting device 34 may further include a time detecting unit 342 and a flow detecting unit 344, where the extended water signal is a timing signal that the duration of the water signal detected by the time detecting unit 342 reaches the preset duration when the flow detecting unit 344 detects that the flow of the water end 4 is less than the preset flow.
Specifically, the time detecting part 342 may be a timer, and the flow detecting part 344 may be a flow meter. When the flow rate of the water use end 4 detected by the flow rate detecting part 344 is smaller than the preset flow rate (for example, 4L/min), the time detecting part 342 starts to count, and when the flow rate of the water use end 4 is maintained smaller than the preset flow rate for a preset time period (for example, 30 s), the user can be considered to need a large amount of hot water, the second detecting device 34 generates an extended water use signal, and sends the extended water signal to the control circuit 40, and the control circuit 40 controls the temporary water outlet valve 32 to be closed and the water inlet valve 26 to be opened.
Further, when the flow rate of the water-using end 4 is greater than the preset flow rate, the user can directly consider that a large amount of hot water is needed, and the hot water is directly heated by the fuel gas to supply the hot water without being limited by time.
In some embodiments, the gas water heater may further include a first water replenishment pipe 50, a first water replenishment valve 52, and a liquid level detection member 54. The first water replenishment pipe 50 is used for connecting the temporary water tank 30 with an external water pipe (i.e., the mother pipe 2). The first water supplementing valve 52 is disposed on the first water supplementing pipe 50 and connected to the control circuit 40. The liquid level detecting unit 54 is used for detecting the liquid level of the temporary water tank 30, and is connected to the control circuit 40. The control circuit 40 controls the first water replenishment valve 52 to be opened and closed according to the liquid level of the water tank 30 to replenish the water tank 30 when the water inlet valve 26 is closed.
In this embodiment, the first water supplementing pipe 50 can supplement the cold water in the main cold water pipe 2 into the temporary water tank 30, and the temporary water tank 30 can be further provided with an electric heating device 60, and the electric heating device 60 is used for heating the supplemented cold water, so that the temporary water tank 30 is always kept with hot water, and the water temperature in the temporary water tank 30 is kept at a proper temperature all the time, so as to be used as temporary standby hot water.
The first water replenishment valve 52 may be embodied as a solenoid valve and the liquid level detection member 54 may be embodied as a liquid level sensor. When the liquid level detection component 54 detects that the water level in the temporary water tank 30 is lower than the first preset value, a liquid level low early warning signal can be sent to the control circuit 40, and the control circuit 40 can open the first water supplementing valve 52 to supplement water to the temporary water tank 30. When the refill reaches the target level, the level detection component 54 may signal the control circuit 40 that refill is complete, and the control circuit 40 may close the first refill valve 52 to stop refilling the temporary tank 30.
In some embodiments, the gas water heater may further include a second water replenishment pipe 70 and a second water replenishment valve 72. The second water replenishment pipe 70 connects the water outlet pipe 24 with the service water tank 30. The second water supplementing valve 72 is disposed on the second water supplementing pipe 70 and is connected to the control circuit 40. The control circuit 40 controls the first water replenishment valve 52 to be opened and closed according to the liquid level of the water tank 30 when the water inlet valve 26 is opened, so as to replenish the water tank 30.
That is, the present embodiment also provides a solution for supplementing water to the temporary water tank 30, that is, the water tank is supplemented with hot water by using the water outlet pipe 24, so that the temporary water tank 30 can be directly supplemented with hot water without heating, and more electric energy is saved.
The second water replenishment valve 72 may be specifically a solenoid valve, and when the liquid level detection component 54 detects that the water level in the temporary water tank 30 is lower than the second preset value, a liquid level low warning signal may be sent to the control circuit 40, and the control circuit 40 may open the second water replenishment valve 72 to replenish water in the temporary water tank 30. When the refill reaches the target level, the level detection component 54 may signal the control circuit 40 that refill is complete, and the control circuit 40 may close the second refill valve 72 to stop refilling the temporary tank 30.
