[0055] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0056] like Figure 1 and 2 As shown in the figure, the present invention provides a preferred embodiment of a control system for a multifunctional water dispenser.

[0057] A control system for a multifunctional water dispenser, the multifunctional water dispenser comprising a hot water mechanism 100, a heat exchange mechanism 200, a cold water mechanism 300 and an ice making mechanism 400, the hot water mechanism 100 comprising a heating module 110, the cold water mechanism 300 and the ice making mechanism 400 sharing a condensing circuit 10, the condensing circuit 10 comprising a compressor 11 and a defrosting valve 13, the ice making mechanism 400 comprising an ice discharging structure, the ice discharging structure comprising a driving member 410 for controlling the ice discharging movement, the hot water of the hot water mechanism 100 flowing into the cold water mechanism 300 after being cooled by the heat exchange mechanism 200, the cold water mechanism 30 0 outputs cold water to the ice-making mechanism 400 to make ice; wherein the control system includes a control unit 500 and a plurality of relay drive circuits 600 connected to the control unit 500, the plurality of relay drive circuits 600 are respectively connected to the heating module 110, the compressor 11, the defrost valve 13 and the drive member 410, and the control unit 500 controls the operation of the heating module 110, the compressor 11, the defrost valve 13 and the drive member 410 through the relay drive circuit 600 to realize that the hot water mechanism 100 heats water, the heat exchange mechanism 200 outputs warm water, the cold water mechanism 300 cools water, and the ice-making mechanism 400 makes ice.

[0058] Specifically, in the hot water mechanism 100, the hot water heated by the heating module 110 can directly flow out through the water outlet 22, or enter the heat exchange mechanism 200. The heat exchange mechanism 200, on the one hand, transports external water to the hot water mechanism 100 for heating, and on the other hand, receives the hot water heated by the hot water structure, thereby cooling it down to warm water. The water sent to the hot water mechanism 100 is preliminarily heated through heat exchange, thereby reducing the heating energy consumption of the heating module 110. Therefore, the control unit 500 controls the heating module 110 through the relay drive circuit 600 to heat it into hot water, and the heat exchange mechanism 200 does not need to be assisted, but serves as an auxiliary structure for warm water output.

[0059] In the cold water mechanism 300, warm water can directly flow out through the water outlet 22, or enter the cold water mechanism 300 to form cold water. The cold water mechanism 300 is provided with a water storage chamber, into which filling liquid flows, and also includes a condenser and a water pipe. The condenser is a pipe of the condensation circuit 10, and the water pipe is a pipe connected to warm water. The condenser circulates condensate and cools it, and cools the liquid flowing in the water pipe through the filling liquid. The warm water flows into cold water after passing through the water pipe. The condensate flowing in the condenser is condensed, and the temperature of the surrounding area is reduced. The filling liquid in the water storage chamber contacts the low temperature area around the condenser, thereby reducing the temperature of the filling liquid and forming a cold filling liquid. The warm water in the water pipe absorbs the low temperature around the condenser through heat exchange with the condenser, so that the temperature of the liquid in the water pipe is reduced, and a cooling effect is achieved. The cooled cold liquid in the water pipe is output to the outside, completing the refrigeration process. The condensing circuit 10 also includes a condenser 12. The compressor 11 and the condenser 12 realize the condensation of the condenser tube. The compressor 11 sucks in the low-temperature and low-pressure refrigerant gas, increases its temperature and pressure by compression, and the high-temperature and high-pressure refrigerant gas enters the condensing pipe. The heat of the refrigerant gas is dissipated inside the condensing pipe through contact with the environment or through the circulation of a cooling medium (such as water). As the heat is dissipated, the refrigerant gas is gradually cooled into a high-pressure liquid. The cooled high-pressure liquid enters the condenser 12 and continues to release heat. After passing through the condenser 12, the refrigerant becomes a high-pressure liquid, and the cooling effect is achieved through the condensing pipe.

[0060] In the ice making mechanism 400, the cold water mechanism 300 and the ice making mechanism 400 share the condensation circuit 10, and a defrost valve 13 is added to the condensation circuit 10. A circuit bypassing the condenser 12 is formed by the defrost valve 13. During the ice making process, the defrost valve 13 is closed, and condensation is performed through the condenser 12 to achieve the freezing operation. Specifically, ice is formed outside the condensation structure in the cold water mechanism 300. After the freezing is completed, the defrost valve 13 is opened, and high-temperature gas is passed into the condenser 12 to achieve thawing, thereby achieving the shedding of ice cubes, thereby obtaining ice cubes. Since the cold water mechanism 300 and the ice making mechanism 400 share the condensation circuit 10, the ice making process will also cause the filling liquid of the water storage chamber in the cold water mechanism 300 to heat up. Therefore, the water after thawing in the ice making mechanism 400 can flow into the water storage chamber as the filling liquid, and the original filling liquid of the water storage chamber is discharged, thereby reducing the temperature of the filling liquid in the water storage chamber, reducing the condensation consumption of the condenser pipe, and reducing the temperature of the cold water discharged from the water pipe.

[0061] At the same time, the water required for ice formation in the ice making mechanism 400 is provided by the cold water mechanism 300, which further reduces the time of ice formation and improves the ice forming efficiency. The driving member 410 makes the melted ice cubes fall into the ice storage space, for example, as a rotating motor, driving the ice cavity to flip so that the melted ice cubes fall into the ice storage space, or adopting other structures to make the ice cubes leave their original positions, so as to realize the rapid collection of ice cubes.

[0062] like Figure 3 As shown in the figures, the present invention provides a plurality of preferred embodiments of control valves.

[0063] The heat exchange mechanism 200 includes a pure water inlet 21 and a warm water outlet 22, and the warm water outlet 22 is also connected to the outlet 22 and the cold water mechanism 300 respectively. The control system also includes: a pure water valve 31 arranged at the pure water inlet 21 of the heat exchange mechanism 200; a hot water valve 32 arranged between the hot water mechanism 100 and the outlet 22; a negative pressure pump 35 arranged between the warm water outlet 22 and the outlet 22; a warm water valve 31 arranged between the hot water mechanism 100 and the outlet 22; a negative pressure pump 35 arranged between the hot water outlet 22 and the negative pressure pump 35; a hot water valve 31 arranged between the hot water mechanism 100 and the outlet 2 ... Valve 33; a cold water valve 34 arranged between the cold water mechanism 300 and the negative pressure pump 35; a warm ice water valve 36 arranged between the negative pressure pump 35 and the water outlet 22, and an ice making valve 37 arranged between the negative pressure pump 35 and the ice making mechanism 400; wherein the pure water valve 31, the hot water valve 32, the negative pressure pump 35, the warm water valve 33, the cold water valve 34, the warm ice water valve 36 and the ice making valve 37 are all connected to the control unit 500 to realize the supply of hot water, warm water and cold water at the water outlet 22, and to realize ice making.

[0064] Specifically, pure water enters the heat exchange mechanism 200 from the pure water inlet 21 and is controlled by the pure water valve 31; after passing through the heat exchange mechanism 200, the pure water is preheated to increase its own hot water, reduce the energy consumption of subsequent heating, and also improve the heating efficiency, and after preheating, it enters the hot water mechanism 100 to be heated and boiled to form hot water, and the hot water valve 32 controls the flow of hot water so that the hot water is supplied to the outside through the outlet 22; the hot water will also enter the heat exchange mechanism 200 to exchange heat with the pure water, the pure water is preheated, and the hot water is cooled to form warm water; the warm water flows out through the warm water outlet 22, The negative pressure pump 35 generates negative pressure to promote the flow of warm water. The warm water can enter the negative pressure pump 35 through the warm water valve 33 and discharge warm water at the water outlet 22 under the control of the warm ice water valve 36. At this time, the cold water valve 34 is in a closed state; if the warm water valve 33 is closed and the cold water valve 34 is opened, the warm water enters the cold water mechanism 300 and discharges cold water. The cold water enters the negative pressure pump 35 through the cold water valve 34. The negative pressure pump 35 generates negative pressure to promote the flow of cold water; the cold water discharges cold water at the water outlet 22 under the control of the warm ice water valve 36, and can also flow into the ice making mechanism 400 under the control of the ice making valve 37.

[0065] Among them, the pure water valve 31, the hot water valve 32, the warm water valve 33, the cold water valve 34, the warm ice water valve 36 and the ice making valve 37 are all valves used to control the flow of fluids. The valves can be opened or closed to control the passage and flow of the fluids. The negative pressure pump 35 is a pump used to generate negative pressure to promote the flow of fluids. The negative pressure pump 35 generates negative pressure to suck warm water or cold water from the warm water valve 33 or the cold water valve 34, and pushes it to the water outlet 22 to supply to the required equipment or area. The control unit 500 can be an electronic controller, a microprocessor or a computer system. It receives input signals and generates corresponding control signals according to preset logic and algorithms to control the operation of valves and pumps. The control unit 500 controls the opening and closing of each valve and the start and stop of the negative pressure pump 35 through control signals, and automatically adjusts the state of the valve and the operation of the pump to achieve precise control of the flow of fluids.

[0066] In this embodiment, the control unit 500 is provided with a hot water mode, a warm water mode, a cold water mode and an ice making mode; in the hot water mode, the control unit 500 controls the pure water valve 31 to open and controls the heating module 110 to heat up to obtain hot water, and controls the opening of the hot water valve 32 to receive hot water; in the warm water mode, the control unit 500 controls the heating module 110 to heat up, controls the pure water valve 31, the warm water valve 33 and the negative pressure pump 35 to open to obtain warm water, and controls the opening of the warm ice water valve 36 to receive Warm water; in the cold water mode, the control unit 500 controls the heating module 110 and the compressor 11 to work, and controls the pure water valve 31, the cold water valve 34 and the negative pressure pump 35 to open to obtain cold water, and obtains cold water by controlling the opening of the warm ice water valve 36; in the ice making mode, the control unit 500 controls the heating module 110 and the compressor 11 to work, and controls the pure water valve 31, the cold water valve 34, the negative pressure pump 35 and the ice making valve 37 to open to obtain ice cubes, and collects ice cubes by controlling the operation of the defrost valve 13 and the driving member 410.

[0067] In hot water mode, refer to Figure 4 The control unit 500 will open the pure water valve 31 to allow the pure water to enter the heat exchange mechanism 200, and control the heating module 110 to start heating to heat the pure water and produce hot water, which is then reheated by the heating mechanism to form boiling hot water. For example, the heat exchange mechanism 200 produces 80-degree water, and the heating mechanism produces 100-degree water. The control unit 500 will also control the opening of the hot water valve 32 to supply hot water to the outside through the water outlet 22. The hot water is also used as the basic water source for other mechanisms, such as the cold water mechanism 300 and the ice-making mechanism 400.

[0068] In warm water mode, refer to Figure 5The core realizes heat exchange through the heat exchange mechanism 200 to obtain warm water, and the warm water can be used as an external supply and also as a water source for the cold water mechanism 300. The control unit 500 opens the pure water valve 31 and the warm water valve 33 to allow the pure water to enter the heat exchange mechanism 200 for heat exchange, and pushes the warm water to the water outlet 22 for supply through the negative pressure pump 35.

[0069] In cold water mode, refer to Figure 6 The control unit 500 controls the operation of the heating module 110 and the compressor 11. The control unit 500 opens the pure water valve 31 and the cold water valve 34, so that the pure water flows into the pure water pipeline of the heat exchange mechanism 200, the heating mechanism, the hot water pipeline of the heat exchange mechanism 200, the cold water mechanism 300, the cold water valve 34 and the negative pressure pump 35 in sequence to form cold water output, which is then output to the outside through the warm ice water valve 36 or input into the ice making mechanism 400 through the ice making valve 37.

The filtering mechanism 42 may include a pre-filter, an activated carbon filter, a nanofilter / ultrafilter, etc. The pre-filter is usually the first filter barrier located at the main water inlet 41, which is used to remove larger suspended particles, sediment, rust, etc. It is usually composed of a mesh filter or a filter; the activated carbon filter is used to remove odors, residual chlorine, organic matter, etc. in water; the nanofilter or ultrafilter is a device that uses a fiber membrane or a porous membrane for filtering, which can remove tiny particles, bacteria, viruses, etc. in water, and can filter out substances with smaller diameters, providing a higher water purification effect. Through multiple filtering and treatment steps, suspended matter, particulate matter, pollutants and microorganisms in water are removed to provide clean and safe drinking water.

[0076] The pressure pump 43 is usually used to increase the pressure of the water source so as to push the water to the subsequent processing and water supply components, such as flowing into the pressure barrel 44. When the pressure barrel 44 needs a low amount of water, the control unit 500 will start the pressure pump 43, which will push the water source to the pressure barrel 44 by connecting with the main water inlet 41, the wastewater outlet 45, the pressure barrel 44, the pressure gauge and the pure water valve 31; the pressure barrel 44 is a container for storing purified water after filtration and treatment. When the pressure pump 43 pushes the water source to the pressure barrel 44, the pressure barrel 44 will accumulate a certain amount of water pressure. When supplying water, the pure water valve 31 can be opened and the water pressure in the pressure barrel 44 can be used to send the purified water into the pure water inlet 21 and supply it to the user. The design of the pressure barrel 44 usually takes into account the storage capacity and pressure stability of water; the pressure gauge is used to measure the pressure of the water in the pressure barrel 44 and provide real-time pressure feedback information to the control unit 500, so that the control unit 500 can adjust the working state of the pressure pump 43 and the opening and closing degree of the pure water valve 31 according to the reading of the pressure gauge.

By controlling the on and off of the relay body 610, the circuit connection between the power supply 710 input terminal and the power supply 710 output terminal can be controlled; the control unit 500 can control the on and off of the relay body 610 by controlling the state of the first control terminal 621, and the heating module 110, the compressor 11, the defrost valve 13 and the driving component 410 are respectively connected to the first power output terminal 623 of the corresponding relay body 610, and the power supply of these devices is controlled by the on and off state of the relay.

[0080] A relay is an electromagnetic switching device that can control the switching operation of a larger current or voltage by changing the current or voltage.
