Wherein the inlet pipe 310 may be used to connect a cold water source, such as a cold water pipe. Water entering from the water inlet pipe 310 may be stored in the tank 330. The heating unit 400 may be provided in the case 330 or outside the case 330 to heat water in the case 330. The outlet pipe 320 is connected to the water inlet end 110 of the main water pipe 100, and water stored in the tank 330 may enter the water inlet end 110 from the outlet pipe 320.
By arranging the water storage tank 300 and the heating unit 400, the gas water heater of the embodiment can preheat the water in the tank body 330 by the heating unit 400 when the temperature is low in winter, so that the water discharged from the shower is the preheated water.
In one embodiment, the gas water heater of the present embodiment may include a control unit 500, and the control unit 500 is connected to the heating unit 400 so that the heating unit 400 may be controlled to be turned on and off.
In one embodiment, the gas water heater of the present example may further include a water proportional valve 600, the water proportional valve 600 having a first passage 610 and a second passage 620. Wherein, the water outlet pipe 320 of the water storage tank 300 can be communicated with the water inlet end 110 of the main water pipe 100 through the first passage 610, and the shower pipeline 10 can be communicated with the water outlet end 120 of the main water pipe 100 through the second passage 620.

That is, the water in the water inlet path P1 may be the water preheated by the heating unit 400, and the water in the water return path P2 may be the water heated by the burner 200.
The control unit 500 may control the opening or closing of the water inlet path P1 by controlling the water proportional valve 600 to open or close the first path 610; the control unit 500 may also control the opening or closing of the return water pathway P2 by controlling the water proportional valve 600 to open or close the second pathway 620.
In one embodiment, the gas water heater of the present embodiment may include a first temperature sensor 710 and a second temperature sensor 720. Wherein the first temperature sensor 710 may be at least partially disposed in the water inlet pipe 310 as long as the water temperature in the water inlet pipe 310 can be sensed. In addition, the first temperature sensor 710 may be a temperature sensing probe. The second temperature sensor 720 may be at least partially disposed in the case 330 as long as the water temperature in the case 330 can be sensed.
The first temperature sensor 710 may transmit a first signal to the control unit 500 when it senses that the water temperature in the water inlet pipe 310 is less than a first threshold value; the control unit 500 may control the heating unit 400 to operate and control the first passage 610 to be closed after receiving the first signal. Wherein the first threshold may be set according to room temperature.
The second temperature sensor 720 may transmit a second signal to the control unit 500 when it senses that the water temperature in the tank 330 is greater than a second threshold; the control unit 500 may control the heating unit 400 to stop operating and control the second passage 620 to be opened after receiving the second signal. Wherein the second threshold may be set according to the desired warm-up temperature.
In the gas water heater of this embodiment, when the water temperature in the water inlet pipe 310 is low, for example, less than the first threshold, the water inlet passage P1 is controlled to be closed, and after the heating unit 400 heats the water in the tank 330 to the preset temperature (the second threshold), the water inlet passage P1 is controlled to be opened, so as to realize automatic control of water outlet instant heating of the shower head.
In one embodiment, the temperature sensor may be one, such as one that may be at least partially disposed in the tank 330 to sense the temperature of the water in the tank 330. The temperature sensor may transmit a first signal to the control unit 500 when it senses that the water temperature in the tank 330 is less than a first threshold; the temperature sensor may transmit a second signal to the control unit 500 when it senses that the water temperature in the tank 330 is greater than a second threshold.
In one implementation, the gas water heater of the present example may further include a residual water return conduit 820 and a water flow sensor 810. The surplus water return pipe 820 is connected between the water ratio valve 600 and the tank 330, and the surplus water return pipe 820, the second passage 620, and the tank 330 may communicate with each other. The water flow sensor 810 is provided in the water inlet pipe 310 or outside the water inlet pipe 310 as long as the water flow in the water inlet pipe 310 can be sensed. The water flow sensor 810 may send a third signal to the control unit 500 upon sensing that the water flow rate in the inlet pipe 310 changes speed to reach a third threshold; after receiving the third signal, the control unit 500 controls to close the first passage 610, and further controls to close the water inlet passage P1; and controls the opening of the second passage 620 and thus the opening of the return water passage P2.
In this embodiment, when the shower is turned off, the water flow in the shower line 10 will be suddenly changed (the water flow speed reaches the third threshold value), and then the water flow in the whole pipeline (including the water inlet pipe 310) will be suddenly changed. The water flow sensor 810 may sense such abrupt change, and then send a third signal to the control unit 500, and the control unit 500 controls to close the water inlet path P1 and open the water return path P2, so that water in the main water pipe 100 may flow back into the tank 330 through the residual water return pipe 820, thereby preventing the main water pipe 100 from being frozen (burst) due to freezing of residual water remaining in the main water pipe 100.
In one embodiment, the gas water heater of the present embodiment may further include a water pump 830 disposed between the water proportional valve 600 and the surplus water return pipe 820. When the control unit 500 receives the third signal, the water pump 830 is controlled to start operating; the water pump 830 may pump the residual water remaining in the main water pipe 100 into the tank 330.
In one embodiment, the gas water heater of the present embodiment may further include a check valve 840 disposed on a path of the surplus water return pipe 840. The check valve 840 may allow water to flow from the water ratio valve 600 to the tank 330 and prevent water in the tank 330 from flowing to the water ratio valve 600, thereby preventing water in the tank 330 from flowing to the shower line 10 or the water ratio valve 600 during operation of the burner 200.
The gas water heater of this embodiment may further include a switch 900 disposed on the water inlet end 110 of the main water pipe 100, and the control unit 500 may control the switch 900 to be turned on after receiving the second signal, so that the preheated water in the tank 330 enters the main water pipe 100.
Other structures of the gas water heater of the present embodiment, such as the fan 20 connected to the burner 200, may be adopted in various technical solutions known to those skilled in the art now and in the future, and will not be described in detail herein.
