Specifically, the water tank assembly 10 is used for storing water for users to take, so as to ensure smooth and continuous water taking. The water intake assembly 20 is used to interact with a user to effect water intake. In some embodiments, the water intake assembly 20 may include a water outlet nozzle. The first water path 61 connects the water tank assembly 10 and the water intake assembly 20, and the first water path 61 is provided with a cooling assembly 30 (e.g., an ice bladder assembly, a compressor assembly, etc.) for cooling water. The second waterway 62 connects the tank assembly 10 and the water intake assembly 20, and the second waterway 62 is provided with a heating assembly 40 (e.g., a hot assembly, a hot tank assembly, etc.) for heating water. The third water path 63 connects the second water path 62 and the tank assembly 10, and the tank assembly 10 and the heating assembly 40 are located on the closed-loop water path formed by the second water path 62 and the third water path 63.

In some embodiments, the end of the second water path 62 connected to the water tank assembly 10 may be a water inlet end, and the end of the second water path 62 connected to the third water path 63 may be a water outlet end, so that the water flowing out of the water tank assembly 10 firstly flows through the second water path 62, and then flows through the third water path 63 after the preliminary sterilization of the heating assembly 40, which is beneficial to improving the sterilization efficiency. Moreover, in the embodiment where the water inlet end of the second waterway 62 is connected to the water tank assembly 10, the water flow direction in the second waterway 62 may be the same in the first sterilization mode and the water taking mode, so as to simplify the structure of the water pump, and simplify the arrangement of the water taking assembly 20 and the water tank assembly 10.

In some embodiments, the heating assembly 40 may be a 2000W instant heating assembly, which may instantly heat pure water to boiling, and may adjust the heating temperature to realize a multi-temperature hot water function. The instant heating component integrates the instant heating element 41, the instant heating control board 42 and other components into a module, and the space of the module is optimized, so that the volume is minimized.

In some embodiments of the present invention, as shown in fig. 2, the waterway system 100 further includes a fourth waterway 64, and the multifunctional water dispenser may further have a second sterilization mode. The fourth waterway 64 is connected to the first waterway 61, and the fourth waterway 64 is used for draining, for example, the outlet end of the fourth waterway 64 may be communicated with the drain port 110 of the multifunctional water dispenser. In some embodiments, the fourth waterway 64 is provided with a drain valve 81 and is used for controlling the on/off of the fourth waterway 64. In the second sterilization mode, the first water path 61 is communicated with the fourth water path 64, so that water can enter the refrigeration assembly 30 from the water tank assembly 10 and then be discharged from the fourth water path 64, and the water in the water tank assembly 10 is discharged, so that water stored in the water tank assembly 10 for a long time can be discharged, and meanwhile, the refrigeration assembly 30 is washed and cleaned; or after the water tank assembly 10 is sterilized at high temperature, the sterilizing water in the water tank assembly 10 may clean and sterilize the cooling assembly 30 and the fourth waterway 64.

In some embodiments of the present invention, the water getting mode may include a normal temperature water mode. It should be noted that the structure for realizing the function of the normal temperature water can be flexibly set.

In some embodiments, in the normal-temperature water mode, the first water path 61 or the second water path 62 is conducted, and the heating assembly 40 and the cooling assembly 30 stop operating. Under the condition that the refrigerating assembly 30 does not refrigerate or the heating assembly 40 does not heat, the normal temperature water in the water tank assembly 10 can flow to the water taking assembly 20 through the first water path 61 or the second water path 62, so that the normal temperature water is obtained, the normal temperature water path does not need to be additionally arranged, and the structure is simplified.

In other embodiments, as shown in fig. 1, the third water path 63 is connected to the water intake assembly 20, and in the normal temperature water mode, the third water path 63 is conducted, so that the normal temperature water in the water tank assembly 10 can flow through the third water path 63 and flow to the water intake assembly 20, and then flow out from the water intake assembly 20, so as to implement the normal temperature water function, and the third water path 63 has the functions of sterilization and normal temperature water discharge, and does not need to additionally provide a normal temperature water path, thereby simplifying the structure.

In some embodiments of the present invention, the first waterway 61, the second waterway 62 and the third waterway 63 may have a conducting state and a blocking state, respectively, so as to switch the flow path of the control water flow through the on-off states of the three waterways, thereby implementing the required function switching and ensuring the efficient performance of the corresponding function. In some embodiments, as shown in fig. 1 and 2, the first waterway 61 may be provided with a first controller, and the first controller may control the on/off of the first waterway 61; the second waterway 62 can be provided with a second controller, and the second controller can control the on-off of the second waterway 62; the third waterway 63 may be provided with a third controller, and the third controller may control on/off of the third waterway 63. Through the cooperation of the first controller, the second controller and the third controller, the on-off states of the first waterway 61, the second waterway 62 and the third waterway 63 can be controlled, so that water flow in the waterway system 100 can flow according to a required path, and the high efficiency of required functions is ensured.

As shown by the hollow arrow in fig. 1, in a state where the first water path 61 is connected and the second water path 62 is disconnected from the third water path 63, water in the water tank assembly 10 flows through the refrigeration assembly 30 and flows to the water intake assembly 20, so as to achieve a cold water intake function; as indicated by solid arrows in fig. 2, in a state where the first water passage 61 is disconnected and the second water passage 62 and the third water passage 63 are connected, water flows between the water tank assembly 10 and the heating assembly 40 to sterilize the water tank assembly 10, the second water passage 62, and the third water passage 63. In a state where the first water path 61 and the second water path 62 are disconnected and the third water path 63 is connected, the water in the water tank assembly 10 flows to the water intake assembly 20 through the third water path 63, so as to realize a function of taking normal temperature water. As shown by the solid arrows in fig. 1, in a state where the first water path 61 and the third water path 63 are disconnected and the second water path 62 is connected, water in the water tank assembly 10 is heated by the heating assembly 40 and flows to the water intake assembly 20, so as to achieve a hot water intake function.

In some embodiments, the first controller may be the first water pump 71. Under the state of first water pump 71 work, not only can make first water route 61 switch on, can also drive rivers and flow, the function integrates, is favorable to improving water intaking efficiency, and the position that sets up of refrigeration subassembly 30, water intaking subassembly 20 and water tank set 10 is more unrestricted, is convenient for adapt to spatial layout.

In some embodiments, the second controller may be the second water pump 72, and the second water pump 72 may not only turn on the second water path 62 but also drive water to flow under the working state, so that the functions are integrated, which is beneficial to improving the water intake efficiency, and the installation positions of the heating assembly 40 and the water tank assembly 10 are not limited, which is convenient for adapting to the spatial layout.

In some embodiments, the second water pump 72 and the heating assembly 40 may be formed as a module, and the space of the module is optimized to minimize the volume.

Of course, in some embodiments, the first controller and the second controller may also be solenoid valves, which are only used to control the on/off of the first water path 61 and the second water path 62, and the flow of the water flow is achieved by gravity through the proper spatial positions of the water tank assembly 10, the refrigeration assembly 30 and the heating assembly 40.

In some embodiments, the third controller is an electromagnetic valve, and different conduction states are realized when the electromagnetic valve is powered on and powered off so as to switch the on-off state of the third water path 63, so that the electromagnetic valve is sensitive to control and stable and reliable in operation. Of course, in some embodiments where the third waterway 63 is used for taking normal temperature water, the third controller may be a water pump to improve water taking efficiency and facilitate spatial arrangement of the water tank assembly 10 and the water taking assembly 20.

In some embodiments of the present invention, the first waterway 61 and the second waterway 62 may be respectively connected to the water intake assembly 20, and the corresponding water intake assembly 20 may be provided with water intake ports respectively corresponding to the two waterways. In other embodiments of the present invention, as shown in fig. 1 and 2, the waterway system 100 further includes a fifth waterway 65, the first waterway 61 and the second waterway 62 are both connected to the water intake assembly 20 through the fifth waterway 65, and the fifth waterway 65 is provided with a water outlet valve 82. Therefore, the water outlet valve 82 is matched with the controllers for controlling on-off of the two water paths, double on-off control is realized, the water leakage preventing effect is good, and the water outlet valve 82 is closed when sterilization is performed, so that high-temperature water can flow among the components such as the water tank assembly 10 and the heating assembly 40, the leakage from the water taking assembly 20 is avoided, and the number of valve bodies is reduced. In addition, the water intake component 20 can only be provided with a water intake, and hot water, cold water and normal temperature water can all flow out through this water intake, have reduced part quantity, make the structure compacter, also avoid appearing the user and get hot water and with the drinking cup with the relative condition in the water intake of play cold water.

Of course, in some embodiments, the third waterway 63 may also communicate with the water intake assembly 20 through the fifth waterway 65, so as to achieve the function of taking normal temperature water through the third waterway 63 and the fifth waterway 65, further simplifying the waterway and reducing the parts.

As shown in fig. 1, in some embodiments where the first water pump 71 is disposed in the first water path 61, the water intake mode includes a cold water mode, in the cold water mode, the first water pump 71 is turned on after the outlet valve 82 is turned on for a second predetermined time (e.g., 0.5 second, etc.), and the outlet valve 82 is turned off after the first water pump 71 stops working for a third predetermined time (e.g., 1 second, etc.), so as to prevent the outlet valve 82 from being pressed to cause no water output in subsequent water intake, thereby ensuring the service life of the components and the sealing reliability of the water path. In addition, under the condition that the water level in the water tank assembly 10 is not lack of water, the water taking operation is not limited, and at the moment, if a cold water taking instruction is received, for example, when a user clicks a water taking button to carry out the cold water taking operation, the water outlet valve 82 can be opened immediately, so that the water outlet efficiency and the sensitivity are improved. When the water intake is stopped, the first water pump 71 stops immediately after receiving the water intake stop signal.

In some embodiments, the cooling state of the cooling assembly 30 and the temperature of the water in the cooling assembly 30 are independent of the water outlet logic, and the water taking operation can be performed even if the water in the cooling assembly 30 is still in the cooling state, but the water out of the water taking assembly 20 is higher than the selected temperature.

In some embodiments, as shown in fig. 1, where the second water pump 72 is disposed in the second water path 62, the water intake mode includes a hot water mode, in which the outlet valve 82 is opened and the heating assembly 40 is operated, and the outlet valve 82 is opened for a fourth predetermined time (e.g., 0.5 seconds, etc.), and then the second water pump 72 is opened. At this time, the water at normal temperature is pumped from the water tank assembly 10 to the heating assembly 40 by the second water pump 72 to be heated, and the heated water is discharged through the water outlet valve 82 in an open state. The heating assembly 40 and the second water pump 72 stop working at the same time, and the water outlet valve 82 is closed after the fifth preset time (such as 1 second) is stopped, so that the subsequent water taking is prevented from being stopped due to the pressure build-up of the water outlet valve 82, and the service life of parts and the sealing reliability of the water path are ensured.

In some embodiments of the present invention, the refrigeration assembly 30 has a water storage cavity and a refrigeration member for refrigerating the water storage cavity, the refrigeration power of the refrigeration member can be low (for example, 60W) by providing the water storage cavity, and the water in the water storage cavity can be left standing for a period of time to be reduced from the normal temperature to the set cold water temperature. When water in the water storage cavity is taken after the water in the water storage cavity is cooled, the cold water in the water storage cavity is pumped out by the first water pump 71 and finally discharged from the water taking assembly 20 through the opened water outlet valve 82. The discharged cold water can be directly drunk or used for preparing bubble water. A water temperature sensor can be arranged in the water storage cavity and used for detecting the water temperature in the water storage cavity so as to control the working state of the refrigerating piece according to the water temperature.

In addition, under the condition that the water temperature in the water storage cavity is higher than the preset cold water temperature value, the refrigerating element runs at high power, so that the water temperature is reduced to the preset cold water temperature value as soon as possible, and the requirement of a user for taking cold water at the required temperature is met; when the water temperature in the water storage cavity is lower than or equal to the preset cold water temperature value, the refrigeration piece stops running or runs at low power, so that the refrigeration assembly 30 enters a standby state or a heat preservation state, and the energy consumption is reduced.

In some embodiments, the hot water outlet may enable multiple water temperature options, such as: boiling water, green tea making water, warm water, milk making water and the like. The heating assembly 40 and the second water pump 72 receive different water outlet temperature signals of the system, and different temperature water outlets are realized by matching different flow rates of the second water pump 72 and heating power of the heating assembly 40 in combination with the NTC value of the inlet and outlet water temperature set on the heating assembly 40.

The waterway system 100 of the multi-functional water dispenser according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings, it being understood that the following description is only exemplary and should not be construed as limiting the invention.

As shown in fig. 1 and 2, a waterway system 100 of a multifunctional water dispenser according to an embodiment of the present invention includes: the water heater comprises a filtering assembly 50, a water tank assembly 10, a refrigerating assembly 30, a heating assembly 40, a water taking assembly 20, a bubble water assembly, a first water channel 61, a second water channel 62, a third water channel 63, a fourth water channel 64, a fifth water channel 65, a sixth water channel 66, a seventh water channel 67 and an eighth water channel 68, a first water pump 71, a second water pump 72, a sterilizing valve 73, a drain valve 81, a water outlet valve 82, a waste water valve 83, a water inlet valve 84, a pressure maintaining valve 86, a booster pump 85 and a water leakage protector 87.

The public demand for drinking water has gradually changed from pure water to multi-functional drinking water, such as hot water, cold water and bubble water. The existing mode for making hot water is generally a single-function multifunctional water dispenser or a kettle, and the operation is inconvenient and complicated; products for modulating cold water are few, and the requirements of common consumers cannot be met; most people choose to buy bottled soda water for cold storage drinking, and cannot know whether additives in the bottled soda water are healthy or not, and the bottled soda water occupies a large space. Therefore, the invention provides a cold and hot integrated multifunctional water dispenser which can filter out pure water and integrate the function of self-making bubble water.

According to the multifunctional water dispenser provided by the embodiment of the invention, the tap water can be filtered, the purified water can be produced, the machine can heat and refrigerate the purified water, the common drinking water requirements are met, and in addition, the self-made bubble water component is arranged, so that the drinking scene is greatly enriched. And the integrated product design can control the volume of the whole machine to be a smaller size, and basically meets the installation scenes of all kitchens or living rooms. And the design of the original water tank is avoided, so that a user does not need to frequently replace the original water tank, and the problem of tap water supply is not needed to be considered after the original water tank is purchased and installed for the first time.

According to the waterway system 100 of the multifunctional water dispenser provided by the embodiment of the invention, a set of control logic for realizing the co-assisted operation of multiple systems is provided, so that the multifunctional integrated operation of the multifunctional water dispenser is realized, and the multi-scene water drinking requirement is met. The method comprises the following specific steps:

water purification system of waterway system 100: as shown by the arrow in the line in fig. 1, when the complete machine is normally powered on, if the water level detection assembly 11 detects that there is a water shortage in the water tank assembly 10, the water inlet valve 84 is opened, the booster pump 85 is started, and the waste water valve 83 is closed. So that the tap water can smoothly enter the filtering assembly 50 for filtering. Therefore, pure water can be supplied to the water tank assembly 10 until the water level sensing assembly 11 senses the water level is full. After the water is full, the filter assembly 50 will start a flushing procedure, i.e. the waste water valve 83 is opened, the booster pump 85 is kept started, and the water inlet valve 84 is also kept opened, and after the flushing in this state is carried out for 30 seconds, the filter assembly 50 is ready to enter a standby state, at this time, the booster pump 85 will stop working, the water inlet valve 84 is also closed, and the waste water solenoid valve will also be closed. The water purification system enters a standby state.

The water level detection assembly 11 includes a sensing signal corresponding to the second predetermined water level and the first predetermined water level. The induction signal corresponding to the second predetermined water level is indicative that the tank assembly 10 is filled with water; when the induction signal corresponding to the first preset water level comes out, the whole machine is started to produce water, and the water taking operation is not interrupted at the moment; if the sensing signal that first predetermined water level corresponds comes out the back and continues the water intaking and drink, because of making water speed and being less than water intaking speed far away, then the final water level of water tank set spare 10 will descend to the water tank bottommost, the sensing signal that third predetermined water level (being minimum water level) corresponds through first predetermined water level, play water velocity of flow signal and system water signal are combined and are calculated and reachd, for preventing to produce heating assembly 40 dry combustion method and the empty scheduling problem of taking out of water pump this moment, the water intaking operation will stop passively, and the complete machine sends out the water shortage warning information, can only carry out the water intaking operation again after water tank set spare 10 is full of water once more.

The hot water taking logic of the waterway system 100: as shown by the solid arrows in fig. 1, when water shortage does not occur in the water tank assembly 10, the water taking operation is not limited, at this time, if the water taking button of the operation panel is clicked to perform hot water taking operation, the water outlet valve 82 is immediately opened, the heating assembly 40 starts to operate while the water outlet valve 82 is opened, the second water pump 72 is also started to operate after the water outlet valve 82 is opened for 0.5 second, at this time, normal-temperature pure water is pumped from the water tank assembly 10 to the heating assembly 40 by the second water pump 72 to be heated, and the heated water is discharged through the water outlet valve 82 in an opened state. The hot water outlet can realize various water temperature selections, such as: boiling water, green tea making water, warm water, milk making water and the like. The heating assembly 40 and the second water pump 72 receive different water outlet temperature signals of the system, and different temperature water outlets are realized by matching different flow rates of the second water pump 72 and heating power of the heating assembly 40 in combination with the NTC value of the inlet and outlet water temperature set on the heating assembly 40. When water taking is stopped, the second water pump 72 and the heating assembly 40 stop working immediately after receiving a water taking stopping signal, and the water outlet valve 82 is also closed after the second water pump 72 stops working for 1 second, so that the water outlet valve 82 is prevented from being pressed to cause no water taking in the subsequent process.

Chilled water logic for waterway system 100: as shown by the hollow arrow in fig. 1, when the water tank assembly 10 is not out of water, the water intake operation is not restricted, and at this time, if the water intake button of the operation panel is clicked to perform the cold water intake operation, the outlet valve 82 is opened immediately, and the first water pump 71 starts pumping water even 0.5 seconds after the outlet valve 82 is opened, so as to pump out the cold water in the refrigeration assembly 30. The discharged cold water can be directly drunk or used for preparing bubble water. When water taking is stopped, the first water pump 71 stops working immediately after receiving a water taking stopping signal, and the water outlet valve 82 is also closed after the first water pump 71 stops working for 1 second, so that the water outlet valve 82 is prevented from being pressed to cause that water cannot be taken out subsequently. The top of refrigeration subassembly 30 is located to water tank set spare 10, the water level in the water tank set spare 10 is higher than the water level in the refrigeration subassembly 30, consequently, the pure water can freely get into and store in the refrigeration subassembly 30, and be provided with the temperature sensor among the refrigeration subassembly 30, temperature in the refrigeration subassembly 30 can be surveyed to this temperature sensor, when the temperature is higher than predetermined cold water temperature value, refrigeration subassembly 30 can full power operation refrigerate, when the temperature reaches predetermined cold water temperature value, refrigeration subassembly 30 will get into standby state or get into low-power heat preservation mode.

High-temperature sterilization control logic: when the machine is not used for a long time, the internal pipeline is easy to breed bacteria in a humid environment, so that high-temperature sterilization can be used for sterilization. As shown by the solid arrows in fig. 2, when the first sterilization mode is started, the water outlet valve 82 is in a closed state, the sterilization valve 73 is immediately opened, after the sterilization valve 73 is opened for 1 second, the second water pump 72 and the heating component 40 are simultaneously opened and heated, the normal-temperature purified water in the water tank assembly 10 is pumped by the second water pump 72, and then is heated by the heating component 40, at this time, the water outlet valve 82 is closed, the sterilization valve 73 is opened, so that the heated water returns to the water tank assembly 10, the water path circulation continues until the water in the water tank assembly 10 is heated to a specified high temperature (the temperature is sensed by the water outlet NTC of the heating component 40), and after the heating is completed, the pipeline continues to circulate for a period of time for sterilization. As shown by the hollow arrow in fig. 2, after the first sterilization mode is completed, the second sterilization mode is started, the second water pump 72 stops working, the first water pump 71 is started to pump the hot water in the water tank assembly 10 out through the refrigeration assembly 30 (the refrigeration assembly 30 does not refrigerate during sterilization), at this time, the water outlet valve 82 is also always in a closed state, the drain valve 81 is opened, and the high-temperature water is discharged from the drain valve 81, and this stage also lasts for a while until the water in the refrigeration assembly 30 is pumped out. After the second sterilization mode is completed, the whole machine enters a standby mode, and all valves, pumps and heating components 40 are closed.
