[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] The following is in conjunction with the appendix Figures 1-5 This embodiment describes a step-type drinking water device with a heat exchanger that dispenses warm water. It includes a drinking water housing 1. From top to bottom, a cold water tank 2, a warm water tank 3, and a step-type hot water tank 4 are sequentially connected to the inner wall of the drinking water housing 1. Cold water is injected through the cold water tank 2. The cold water tank 2 is connected to the warm water tank 3, and the warm water tank 3 is connected to the step-type hot water tank 4 via a solenoid valve pipe 5. The warm water tank 3 and the step-type hot water tank 4 are equipped with level sensors, and the step-type hot water tank 4 is equipped with a temperature sensor. The level sensors and temperature sensors can send signals to a controller. The controller controls the opening and closing of the solenoid valve tube 5 based on the liquid level and temperature electrical signals. The upper part of the stepping hot water tank 4 is connected to the water suction mechanism 6, which can draw hot water from the upper part of the stepping hot water tank 4 and discharge it. Multiple steam pipes 7 are connected to the upper edge of the upper surface of the stepping hot water tank 4. The steam pipes 7 extend upward to the upper part of the warm water tank 3. The steam pipes 7 are connected to the downward inclined stepped pipe 8. The end of the stepped pipe 8 is located at the lower part of the warm water tank 3 and extends to the outside of the drinking water shell 1. The lower part of the warm water tank 3 is connected to the warm water pipe 9.

[0025] In use, water is injected into the cold water tank 2, and the water level sensor in the warm water tank 3 and the step hot water tank 4 sends an electrical signal to the controller that the water level is not up to standard, the controller controls the electromagnetic valve pipe 5 to open, cold water enters the warm water tank 3 and the step hot water tank 4, the heating element in the step hot water tank 4 heats the cold water, and the multiple water level sensors and temperature sensors in the step hot water tank 4 send electrical signals to the controller, and the controller controls the electromagnetic valve pipe 5 at the lower part of the warm water tank 3 to open intermittently, completing the step heating of the cold water, and the hot water is always located in the upper layer of the step hot water tank 4. When cold water is needed, the water pumping mechanism 6 pumps the hot water in the upper layer of the step hot water tank 4 and discharges it, and the steam generated by the step hot water tank 4 is directly discharged to the upper part of the warm water tank 3 through the vertically arranged steam pipe 7. Because the path is the shortest, the steam will not condense and flow back in the steam pipe 7 during the process, and then the steam travels along the downward inclined ladder pipe 8. The ladder pipe 8 ensures that the condensed water is smoothly discharged and cannot be accumulated, while greatly prolonging the steam travel, so that the steam is fully condensed and the steam heat is transferred to the water in the warm water tank 3. When warm water is needed, the warm water pipe 9 is opened, which solves the technical problem that the steam waste heat of the existing step type drinking water equipment is not fully utilized because the condensing pipe shape is too simple, resulting in the mixture of steam and condensed water being discharged.

The liquid pumping pump 65 is connected to the top wall of the step hot water tank 4.

[0031] When the water level reaches the first liquid level sensor 63, the controller controls the electromagnetic valve pipe 5 to stop water injection, and when the temperature sensor 64 at the lower end of the longest liquid suction pipe 61 detects that the temperature of the water at the lowermost layer reaches the preset value, the controller controls the electromagnetic valve pipe 5 to open, at which time the warm water in the warm water tank 3 heated by steam enters the step-by-step hot water tank 4 until the liquid level reaches the next liquid level sensor 63. When water needs to be drained, the control liquid suction pump 65 is opened, the controller controls the electromagnetic valve 62 on the liquid suction pipe 61 at the last triggered liquid level sensor 63 to open, and the remaining electromagnetic valves 62 to close, and the liquid suction pump 65 sucks the upper layer of hot water between the two liquid level sensors 63 and discharges it through the hot water pipe 66, realizing step-by-step heating, and the water taken at any time is the upper layer of hot water.
