[0033] As shown in Figures 1 to 7, the water heater provided in the embodiment of the present application includes a shell 1, a valve 2 and an actuator 3. The shell 1 is provided with a water inlet 11, a heating chamber 12, a valve chamber 13, a first water outlet 14 and a second water outlet 15. The valve 2 is installed in the valve chamber 13 and divides the valve chamber 13 into a first sub-chamber 131, a second sub-chamber 132 and a third sub-chamber 133.

[0034] The actuator 3 is connected to the valve 2 , and is used to drive the valve 2 to operate, so that the valve 2 can switch between a first state, a second state, and a third state.

[0035] As shown in Figure 5, in the first state of the valve 2, the first sub-chamber 131 is in communication with the second sub-chamber 132, and the first sub-chamber 131 is isolated from the third sub-chamber 133. As shown in Figure 6, in the second state of the valve 2, the first sub-chamber 131 is in communication with the third sub-chamber 133, and the first sub-chamber 131 is isolated from the second sub-chamber 132. As shown in Figure 7, in the third state of the valve 2, the first sub-chamber 131 is in communication with both the second sub-chamber 132 and the third sub-chamber 133.

[0036] The water heater provided in the embodiment of the present application has a heating chamber 12 and a valve chamber 13 disposed on the housing 1. Coolant enters the heating chamber 12 through the water inlet 11, where it is heated and then flows directly into the first sub-chamber 131. The actuator 3 drives the valve 2 to control the communication between the first sub-chamber 131, the second sub-chamber 132, and the third sub-chamber 133. This water heater integrates the valve chamber 13 of the three-way valve with the internal flow channel 121 of the heating chamber 12, and positions the actuator 4 externally. This results in a more compact structure, small footprint, high space utilization, and reduced piping costs.

[0037] In one embodiment, as shown in Figures 2 to 7 , an inner flow channel 121 is formed in the heating chamber 12. The inlet of the inner flow channel 121 is connected to the water inlet 11, and the outlet of the inner flow channel 121 is connected to the first sub-chamber 131.
