Description

Technical Field

[0001] The utility model relates to the technical field of pipeline machines, in particular to a pipeline machine water channel structure with a high-temperature sterilization function. Background Art

[0002] Pipeline machine, also known as pipeline water dispenser or wall-mounted pipeline machine, is a high-end drinking water equipment that can directly heat and cool the water flowing out of the water purifier, providing water of various temperatures to meet the user's instant drinking needs. Depending on the installation method, pipeline machines can be divided into three types: wall-mounted, vertical and countertop. They are mainly used in homes, offices and other places.

[0003] However, existing pipeline dryers have relatively simple functions and lack a sterilization effect. As bacteria easily grow inside the waterway of pipeline dryers during long-term use, the lack of sterilization in the waterway will affect the water quality of the pipeline dryer and even seriously endanger people's health. To this end, we propose a pipeline dryer waterway structure with high-temperature sterilization function. Utility Model Content

[0004] The main purpose of the utility model is to provide a pipeline machine water channel structure with a high-temperature sterilization function, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a pipeline machine water channel structure with a high-temperature sterilization function, comprising an inner water tank, a water outlet is provided above the inner water tank, a heating element is provided on one side of the inner water tank, a water inlet pipe is provided below the inner water tank, a reversing valve is provided above the heating element, a first water inlet solenoid valve and a second water inlet solenoid valve are provided at one end of the water inlet pipe, the first water inlet solenoid valve is located on one side of the second water inlet solenoid valve, a high liquid level sensor is detachably connected to the inner surface of the upper end of the inner water tank, and a low liquid level sensor is detachably connected to the inner surface of the lower end of the inner water tank;

[0006] When the high liquid level sensor detects whether the water level inside the inner water tank is high, if it is not high, the water inlet pipe will fill the inner water tank with water through the first water inlet solenoid valve. If it is high, the water pump of the heating element will work and the heating element will start at the same time. The heating element will circulate the preheated water through the reversing valve to the inner water tank. When the water temperature in the inner water tank reaches 85°, the heating element will stop heating and sterilize for 1-5 minutes. After that, the reversing valve will be switched to the water outlet to start draining the 85° water in the inner water tank. The water pump of the heating element will pump water to sterilize the entire water channel.

[0007] Preferably, a water inlet conduit is provided between the first water inlet solenoid valve and the inner water tank, and a first superheating pipe is provided between the heating element and the inner water tank.

[0008] Preferably, a second superheating pipe is provided between the heating element and the reversing valve, and a normal temperature conduit is provided between the second water inlet solenoid valve and the water outlet.

[0009] Preferably, a one-way valve is provided between the reversing valve and the normal temperature conduit, a return pipe is provided between the reversing valve and the inner water tank, and a steam pipe is provided between the inner water tank and the water outlet.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] When the high liquid level sensor detects whether the water level inside the inner water tank is high, if it is not high, the water inlet pipe fills the inner water tank with water through the first water inlet solenoid valve. If it is high, the water pump of the heating element works and the heating element starts at the same time. The heating element pumps the preheated water through the reversing valve to the inner water tank. When the water temperature of the inner water tank reaches 85°, the heating element stops heating and sterilizes for 1-5 minutes. After that, the reversing valve is switched to the water outlet to start draining the 85° water in the inner water tank. The water pump of the heating element 3 pumps water to sterilize the entire water channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model provides a pipeline machine water circuit structure with a high-temperature sterilization function. When the high liquid level sensor 15 detects whether the water level inside the inner water tank 1 is high, if it is not a high water level, the water inlet pipe 4 fills the inner water tank 1 with water through the first water inlet solenoid valve 6. If it is a high water level, the water pump of the heating element 3 works, and the heating element 3 is started at the same time. The heating element 3 circulates the preheated water through the reversing valve 5 to the inner water tank 1. When the water temperature of the inner water tank 1 reaches 85°, the heating element 3 stops heating and sterilizes for 3 minutes. After that, the reversing valve 5 is switched, switched to the water outlet 2, and the 85° water in the inner water tank 1 begins to be drained. The water pump of the heating element 3 pumps water to sterilize the entire water circuit.

[0019] In one embodiment provided by the present invention, a water inlet conduit 8 is provided between the first water inlet solenoid valve 6 and the inner water tank 1, and a first superheating pipe 9 is provided between the heating element 3 and the inner water tank 1.

The steam pipe 14 can discharge the water vapor in the inner water tank when in use.

When the pipeline machine is in use, when the heating module detects that the water inlet temperature reaches 85°C, the internal pipeline is circulated and sterilized for 3 minutes. During the flushing period, the sterilization indicator light is on, and other indicator lights are off. The digital tube displays a 180S countdown, and all buttons cannot be used normally. After the 180S countdown, the flushing is completed and the buzzer emits a "ding dong ning" prompt sound, the sterilization indicator light is off, the drainage indicator light is on, the water receiving container is put away, and the water outlet button is pressed to drain. The digital tube displays a 120S countdown. During the drainage process, if the water receiving container is full, press the water outlet button to pause the water discharge and countdown, put the water receiving container again, press the water outlet button again, continue draining, and continue countdown. After the 120S countdown, the drainage is completed and the machine enters normal use status (the water volume and mode are both the mode before sterilization).
