Description

Technical Field

[0001] The utility model belongs to the technical field of water drinking machines, and in particular relates to a water drinking machine that realizes pipe-free water storage in a water outlet pipe section. Background Art

[0002] In view of the fact that the distance from the hot tank to the water outlet of the existing built-in hot tank water dispenser or water purifier with hot water outlet function is relatively far, the hot water from the hot tank to the water outlet contains room temperature water, which results in a lower water temperature in the pipe when taking water, resulting in a large difference between the temperature of the water received in the container and the water temperature in the hot tank. In addition, water stored in the pipe is also prone to breed bacteria. To solve this problem, it is necessary to design a water dispenser system without water stored in the pipe. Utility Model Content

[0003] The utility model provides a zero-pipe water storage drinking fountain, which comprises a hot water tank, a water inlet, a hot water outlet, a hot water outlet pipe, an air inlet, an air outlet, a temperature sensor and a liquid level sensor, and a water pump with a switchable water delivery reverse direction is arranged on the hot water outlet pipe, so that after the water is discharged, the water in the hot water outlet pipe can be pumped back to the hot water tank, so as to avoid the problem of water accumulation in the hot water outlet pipe, which causes the hot water in the water pipe to cool down after the water is discharged for a long time, and the inconvenience caused by the need to drain the water for a long time before the hot water can be output when it is used next time.

[0004] The utility model aims to provide a zero-pipe water storage drinking fountain, which comprises a hot water tank, a water inlet, a hot water outlet, a hot water outlet pipe, an air inlet, an air outlet, a temperature sensor and a liquid level sensor.

[0005] The hot water outlet pipe connects the hot water tank and the hot water outlet. A water pump with a changeable water delivery direction is arranged on the hot water outlet pipe. Preferably, a water pump with a changeable water delivery direction is arranged at one end of the hot water outlet pipe near the hot water tank.

[0006] The zero-tube water storage drinking fountain provided by the utility model has the following beneficial effects:

[0007] (1) The utility model has a reasonable design and easy functional control. The liquid level sensor is provided to realize automatic water inlet and water inlet stop. The temperature sensor is provided to realize temperature control and realize automatic heating and heating stop.

[0008] (2) The zero-pipe water storage water dispenser of the utility model is provided with a water pump with a changeable water delivery direction on the hot water outlet pipe, so that after the water delivery is finished, the water in the hot water outlet pipe is pumped back to the hot water tank until the water level probe detects that there is no water in the hot water pipe and the reverse pumping stops. This avoids the problem that water is stored in the hot water outlet pipe, and the hot water in the water pipe cools down when the water is delivered at a long interval. The next time it is used, it takes a long time to drain the water before the hot water can be delivered, causing inconvenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in detail below through specific implementation modes, and the features and advantages of the present invention will become clearer and more explicit with these descriptions.

[0022] The utility model provides a zero-pipe water storage drinking fountain, which comprises a hot water tank 1, a water inlet 2, a hot water outlet 3, a hot water outlet pipe 4, an air inlet 5, an air outlet 6, a temperature sensor 7 and a liquid level sensor 8. A water level probe 10 is also provided.

[0023] The hot water tank 1 stores water. A heating body is arranged at the bottom of the hot water tank 1 to heat and keep the stored water warm. The utility model does not impose any limitation on the heating body, and any component that can be heated can be used, such as stainless steel pipe heating.

[0024] The water inlet 2 is arranged at the lower part of the side of the hot water tank 1 for replenishing water. A one-way valve is arranged between the water inlet 2 and the hot water tank 1 to achieve one-way water inflow and prevent the water in the hot water tank 1 from flowing back.

[0025] The hot water outlet pipe 4 connects the hot water tank 1 and the hot water outlet 3. A water pump 9 with a changeable water delivery direction is provided on the hot water outlet pipe 4. Preferably, the water pump 9 with a changeable water delivery direction is provided at one end of the hot water outlet pipe 4 near the hot water tank 1. A water level probe 10 is provided on the water pipe between the water pump 9 with a changeable water delivery direction and the hot water outlet 3. Preferably, the water level probe 10 is provided near the water pump 9 with a changeable water delivery direction. One end of the hot water outlet pipe 4 is connected to the bottom of the hot water tank 1. When the user opens the hot water outlet 3, the water pump 9 with a changeable water delivery direction is controlled to extract hot water from the hot water tank 1 for the user to use. When the user closes the hot water outlet 3, the water pump 9 with a changeable water delivery direction is controlled to start, and the hot water outlet pipe 4 is drawn back into the hot water tank 1 until the water level probe 10 detects that there is no water in the hot water outlet pipe and stops, so as to prevent the hot water outlet pipe 4 from storing water for a long time, resulting in a decrease in water temperature or water mixing, and to avoid the inconvenience caused by the need to drain water for a long time to output hot water that meets the required temperature when using it next time.

[0026] The temperature sensor 7 is arranged on the upper part of the hot water tank 1 and is used to test the temperature of the water stored in the hot water tank 1. When the temperature reaches a preset temperature, the heating body is controlled to stop heating.

[0027] The liquid level sensor 8 is arranged on the top of the side of the hot water tank 1. When water is replenished, when the water level rises to the liquid level sensor 8, the liquid level sensor 8 sends a signal to control the water inlet to stop.

[0028] The air inlet 5 and the air outlet 6 are arranged at the top of the hot water tank 1 to balance the pressure inside and outside the hot water tank 1 and ensure normal water discharge.

[0029] A one-way valve is arranged on the pipeline connecting the air inlet 5 to the hot water tank 1, so that air can enter the hot water tank 1 from the outside in one direction. An air filter element, such as an H13 type air filter element, is arranged between the air inlet 5 and the one-way valve, so that the incoming air is first filtered and purified by the air filter element before entering the hot water tank 1.

[0030] A one-way valve is arranged on the pipeline connecting the air inlet 6 to the hot water tank 1 , so that air is discharged from the hot water tank 1 in one direction.

[0031] The present invention is described in detail above in conjunction with the specific implementation methods and the accompanying drawings, but these descriptions cannot be understood as limiting the present invention. Those skilled in the art understand that, without departing from the spirit and scope of the present invention, the technical solution of the present invention and its implementation methods may be subjected to a variety of equivalent substitutions, modifications or improvements, all of which fall within the scope of the present invention. The scope of protection of the present invention shall be subject to the attached claims.
