[0028] This embodiment provides a hot water container, such as Figures 1-5 As shown, the hot water tank includes a tank body and a water outlet pipe. The tank body is used to hold water, and the water outlet pipe has an inner tube extending from the top of the tank body to its bottom. The extended end of the inner tube has a water inlet; the water inlet is higher than the bottom wall of the tank body. The water outlet pipe extends from the outside of the tank body into the tank body, allowing water to be drawn out through the water inlet. Since the water inlet is higher than the bottom wall of the tank body, this prevents the tank from being completely emptied during drawing water, thus avoiding dry burning of the hot water tank. Compared to having an opening at the bottom of the tank body as the water outlet, extending the water outlet pipe into the tank body prevents the hot water tank from rusting.
[0029] Specifically, such as Figure 2 and Figure 3 As shown, the water inlet is a pipe-shaped structure. The water inlet being higher than the bottom wall of the tank means that at least the lower edge of the water inlet is higher than the bottom wall of the tank, so that there is always a space for water to be stored between the bottom of the water inlet and the bottom wall.
[0030] like Figure 1 and Figure 2As shown in FIG. 1, the heat tank further comprises a motor pump, which is arranged below the tank body; the water outlet pipe is in communication with the motor pump and extends upwards to the top of the tank body outside the tank body, and then extends to the inside of the tank body after bending.

[0034] Further, the heat tank further has a controller, and the motor pump and the lowest water level probe are respectively electrically connected with the controller, so that the controller controls the motor pump according to the lowest water level probe. Specifically, when the controller receives the signal of the lowest water level probe, the controller controls the motor pump to stop drawing water.
[0035] As shown in FIG. 1, the heat tank further comprises a motor pump, which is arranged below the tank body; the water outlet pipe is in communication with the motor pump and extends upwards to the top of the tank body outside the tank body, and then extends to the inside of the tank body after bending. The motor pump can draw water from the inside of the tank body through the water outlet pipe outside the tank body. Figure 3As shown, the tank body has a first height, the extension length of the lowest water level probe in the tank body has a second height, and the extension length of the inner tube body in the tank body has a third height, the first height being greater than the second height and the third height.
