[0002] Water dispenser is a commonly used drinking water equipment in modern life. It is mainly composed of a shell, an internal water system and a control board. The control board controls the operation of various valves, pumps, heating modules and electronic ice tanks in the water system according to the instructions issued by the customer, thereby meeting the user's water needs. During long-term use, the internal components of the water dispenser need to be sterilized at high temperature. At present, when high-temperature sterilization is performed inside the water dispenser, valves and pumps are generally added to transport high-temperature water to the components that need to be sterilized. The sterilization water circuit with multiple valves and pumps makes the water system of the water dispenser more complicated. The increase in configuration causes the cost of the entire water dispenser to rise. At the same time, the increase in components will also lead to a decrease in the reliability of the system operation. Utility Model Content

[0016] The utility model has the beneficial effects:

[0017] 1. In the utility model, the electric multi-way switching valve is mainly composed of a valve sleeve, a valve core, a valve seat and related interfaces. The valve core is divided into two independent first water chambers and a second water chamber by a partition. The two water chambers are respectively connected to the water inlet and the water outlet. When the valve core rotates, the internal channel thereof will be aligned or staggered with the interface on the valve sleeve accordingly, so as to control the on-off of the water flow. The first water chamber is directly connected to the water inlet. Through the rotation of the valve core, the water path between the first water diversion inlet or the second water diversion inlet and the first water chamber can be controlled to be connected or closed. The second water chamber is directly connected to the water outlet and is kept in a normally open state with the first water diversion outlet. No matter how the valve core rotates, the second water diversion outlet can always receive water flow from the second water chamber. However, in particular, when the second water chamber is connected to the first water diversion outlet, , the water path between the second water outlet and the second water chamber will be in a sealed state to avoid unnecessary diversion of water flow here. When the electric multi-way valve is applied to the water dispenser system, the valve has multiple water outlet and water inlet interfaces, and the on and off of each water path can be controlled by rotating the valve core. It can flexibly switch the water flow between multiple inputs and outputs to meet the needs of complex water path systems, and thus can meet the cold water and hot water needs of the water dispenser system without adding redundant valves, and can also meet the needs of sterilization water paths, thereby optimizing the water path structure of the entire water dispenser system, simplifying the configuration, and reducing the manufacturing cost of the water dispenser. The mechanical structure is reasonably designed, so that the switching valve maintains stable performance in long-term use, thereby ensuring the reliability of the operation of the entire water dispenser system.

[0018] 2. After the electric multi-way switching valve is installed in the water dispenser system, the source water in the source water tank enters the electronic ice tank and the electric multi-way switching valve through the pipeline respectively. The electronic ice tank will cool the water from the source water tank. When the user needs normal temperature water, the control board controls the drive motor to rotate and drives the valve core to rotate a certain angle. The source water enters the first water cavity through the second water inlet and the third water hole. At this time, the water path between the first water inlet and the first water cavity is closed, and then the diaphragm pump works to pump the normal temperature source water in the first water cavity through the first water port and the water outlet to the heating module. At this time, the heating module does not work, and the normal temperature source water enters the second water cavity through the water inlet and the second water port, and finally enters the second water cavity through the fifth water hole and the water outlet. The second water outlet is transported to the water outlet. At this time, the water path between the first water outlet and the second water cavity is closed. When hot water is needed, after the source water enters the heating module, the control board controls the heating module to heat the room temperature source water to the set temperature, and finally transports it to the water outlet from the second water outlet. When ice water is needed, the control board controls the electronic ice tank to cool the room temperature water to the design temperature, the valve core rotates, and the ice water enters the first water cavity through the first water inlet and the second water hole. At this time, the water path between the second water inlet and the first water cavity is closed, and the diaphragm pump pumps the ice water in the first water cavity to the heating module. At this time, the heating module does not work, and the ice water enters the second water cavity through the water inlet and the second water outlet, and finally is transported to the water outlet from the second water outlet. The fifth water hole and the second water diversion outlet are transported to the water outlet. At this time, the water path between the first water diversion outlet and the second water cavity is closed; when the electronic ice chamber needs to be sterilized at high temperature, the valve core rotates to connect the first water diversion inlet with the first water hole, and the fourth water hole with the first water diversion outlet. The diaphragm pump draws water into the heating module and heats it to the temperature required for disinfection. The water then enters the second water cavity through the water inlet and the second water inlet, and then enters the first water diversion outlet through the fourth water hole. At this time, the water path between the fifth water hole and the second water diversion outlet is closed to prevent high-temperature water from flowing out of the water outlet. Finally, the water enters the electronic ice chamber through the pipeline to achieve high-temperature sterilization inside the electronic ice chamber. The sterilized water will be sterilized by the electronic ice chamber again. It is used for cooling. An electric multi-way switching valve is used to meet the complex water circuit requirements of the water dispenser system. The on and off of each water circuit can be controlled by rotating the valve core, and the water flow can be flexibly switched between multiple inputs and outputs, thereby meeting the needs of the complex water circuit system of the water dispenser. Without adding extra valves, the cold water and hot water requirements of the water dispenser system can be met, and the needs of the sterilization water circuit can also be met, thereby optimizing the water circuit structure of the entire water dispenser system, simplifying the configuration, and reducing the manufacturing cost of the water dispenser. The reasonable design of the mechanical structure enables the switching valve to maintain stable performance in long-term use, thereby ensuring the reliability of the operation of the entire water dispenser system.

[0044] In this embodiment, Figure 1-Figure 5As shown, the water dispenser system includes a source water tank 38, an electronic ice tank 39, a diaphragm pump 41, an electric multi-way switching valve body 40, a heating module 42, and a water outlet 43. The electronic ice tank 39 is an existing product and can cool the internal source water to a required temperature. The heating module 42 is also an existing product and can heat the internal source water to a required temperature. The diaphragm pump 41 is also an existing product and can realize flow control and water pumping. After the electric multi-way switching valve is installed in the water dispenser system, the source water in the source water tank 38 enters the electronic ice tank 39 and the electric multi-way switching valve through pipelines respectively. The electronic ice tank 39 will cool the source water from the source water tank 38. When the user needs water at room temperature, the control board controls the drive motor 01 to rotate. The valve core 09 is driven to rotate a certain angle, and the source water enters the first water chamber 15 through the second water inlet 13 and the third water hole 14. At this time, the water path between the first water inlet 10 and the first water chamber 15 is closed, and the ice water in the electronic ice tank 39 cannot enter the electric multi-way switching valve body 40. Then the diaphragm pump 41 works to pump the normal temperature source water in the first water chamber 15 through the first water port 19 and the water outlet 18 to the heating module 42. At this time, the control board controls the heating module 42 not to work, and the normal temperature source water in the heating module 42 enters the second water chamber 26 through the water inlet 21 and the second water port 22. The fifth water hole 24 and the second water outlet 25 are in the normally open state. Finally, the fifth water hole 24 and the second water outlet 2 5 is delivered to the water outlet 43. At this time, the position of the valve core 09 makes the fourth water hole 27 and the first water outlet 28 misaligned, and then the water path between the first water outlet 28 and the second water chamber 26 is closed; when hot water is needed, the source water still enters the first water chamber 15 through the second water inlet 13 and the third water hole 14, and then is delivered to the water inlet end of the diaphragm pump 41 through the water outlet 18, and is pumped to the heating module 42 by the diaphragm pump 41. The control board controls the heating module 42 to heat the normal temperature source water to the set temperature, and the hot water is delivered to the water inlet 21 through the pipeline, enters the second water chamber 26 through the second water outlet 22, and is finally delivered to the water outlet 43 from the second water outlet 25; when ice water is needed, the control board controls the electronic ice tank 3 9 Cool the normal temperature water to the design temperature, the valve core 09 rotates, so that the first water inlet 10 is aligned and connected with the second water hole 37, and the ice water enters the first water chamber 15 through the first water inlet 10 and the second water hole 37. At this time, the water path between the second water inlet 13 and the first water chamber 15 is closed, and the diaphragm pump 41 pumps the ice water in the first water chamber 15 to the heating module 42. At this time, the heating module 42 does not work, and the ice water enters the second water chamber 26 through the water inlet 21 and the second water inlet 22, and is finally transported to the water outlet 43 through the fifth water hole 24 and the second water outlet 25. At this time, the fourth water hole 27 is misaligned with the first water outlet 28, so that the water path between the first water outlet 28 and the second water chamber 26 is closed;When the electronic ice chamber 39 needs to be sterilized at high temperature, the valve core 09 rotates, so that the first water inlet 10 is connected to the first water hole 08, the fourth water hole 27 is connected to the first water outlet 28, and the diaphragm pump 41 draws water into the heating module 42 to heat it to the temperature required for disinfection, and then enters the second water cavity 26 through the water inlet 21 and the second water hole 22, and then enters the first water outlet 28 through the fourth water hole 27. At this time, the water path between the fifth water hole 24 and the second water outlet 25 is closed to prevent high-temperature water from flowing out of the water outlet 43, and finally enters the electronic ice chamber 39 through the pipeline, so as to achieve high-temperature sterilization inside the electronic ice chamber 39. The sterilized water will be cooled and used again by the electronic ice chamber 39. This solution realizes the complex waterway requirements of the water dispenser system through an electric multi-way switching valve body 40. The on-off of each waterway can be controlled by rotating the valve core 09, and the water flow can be flexibly switched between multiple inputs and outputs, thereby meeting the requirements of the complex waterway system of the water dispenser. In addition, without adding redundant valves, the cold water and hot water requirements of the water dispenser system can be met, and the requirements of the sterilization waterway can also be met, thereby optimizing the waterway structure of the entire water dispenser system, simplifying the configuration, and reducing the manufacturing cost of the water dispenser. The reasonable design of the mechanical structure enables the switching valve to maintain stable performance in long-term use, thereby ensuring the reliability of the operation of the entire water dispenser system. ;
