Description

Technical Field

[0001] The present invention relates to the technical field of drinking water equipment, and in particular to a water channel optimization system of drinking water equipment and a control method thereof. Background Art

[0002] As the quality of life of modern people improves, various drinking water equipment has entered the home, and people's requirements for the experience of drinking water equipment are increasing. Initially, the under-sink water purifiers on the market usually simply provide water purification functions. Recently, hot and cold drinking water equipment with integrated heating and cooling functions have gradually entered thousands of households, and under-sink water purifiers with integrated heating and cooling functions have also become a major development trend of drinking water equipment products.

[0003] At present, there are two main cooling methods for drinking water equipment on the market, one is compressor refrigeration, and the other is electronic semiconductor refrigeration (usually called electronic ice tank). Among them, the compressor refrigeration method has relatively large vibration noise and large size, which is not suitable for integration in under-sink water purifiers. Therefore, the noiseless, vibration-free, small-sized and easy-to-control electronic ice tank refrigeration has gradually become the mainstream cooling method for under-sink water purifiers.

[0004] The existing hot and cold integrated drinking water equipment using electronic ice bladder refrigeration usually includes a composite filter element, a normal temperature water path, a heating water path, a cooling water path, and a water outlet connected to the output ends of the three water paths, such as the attached Figure 1 As shown, the raw water inlet pipeline is connected to the first water inlet end (pre-filter unit) of the composite filter element 1, the first water outlet end of the composite filter element 1 is connected to the water inlet end of the booster pump 12 via the first control valve 11, the water outlet end of the booster pump 12 is connected to the second water inlet end (reverse osmosis membrane filtration unit) of the composite filter element 1, and the pure water output from the second water outlet end of the composite filter element 1 flows into three water channels respectively, a second control valve 21 is provided on the normal temperature water channel 2, a third control valve 31 and a heater 32 are provided on the heating water channel 3, a fourth control valve 41 and an electronic ice tank 42 are provided on the cooling water channel 4, a fifth control valve 43 is provided between the water outlet of the electronic ice tank 42 and the water outlet nozzle 5, and a sixth control valve 6 is provided on the drain outlet of the electronic ice tank 42, wherein the electronic ice tank is usually composed of an electronic ice tank water tank, a heat sink and a fan.

[0005] Whether it is compressor refrigeration or electronic ice tank refrigeration, it needs to rely on heat exchange with the external environment to achieve rapid refrigeration. However, the operating environment of the under-sink water purifier is a closed environment inside the kitchen cabinet. The heat in the closed environment is not easy to dissipate. This will inevitably cause the electronic ice tank refrigeration system of the under-sink water purifier to take longer to dissipate heat to lower the water temperature. The refrigeration efficiency is significantly reduced, and it is difficult to avoid the situation where the cold water temperature obtained by the user is not low enough when the user takes water for the first time, affecting the user's experience. Summary of the invention

[0025] The beneficial technical effects of the present invention include at least:

[0026] 1. The water circuit optimization system and control method of the drinking water equipment are adopted. The auxiliary heat dissipation circulation water circuit is formed by designing a water tank, a water pump, an eighth control valve and a heat dissipation water circuit component. By utilizing the circulation of water, the heat dissipation water circuit component can effectively absorb the heat generated by the electronic ice bladder, accelerate the hot and cold alternation of the electronic ice bladder, and evenly distribute the heat to the entire auxiliary heat dissipation circulation water circuit and the water tank, avoiding local overheating and improving the thermal stability of the system to continuously assist in the heat dissipation of the electronic ice bladder. This design can achieve effective heat dissipation in a closed space, reduce the influence of the closed environment under the kitchen on the heat dissipation effect of the electronic ice bladder, thereby quickly reducing the temperature of the electronic ice bladder and improving the cooling efficiency of the entire drinking water equipment under the kitchen; combined with The arrangement of temperature sensors in the water tank and on the heat dissipation water circuit components and the structural design of the controllable water tank auxiliary cooling passage can monitor the water temperature in the water tank and the water temperature on the heat dissipation water circuit components in real time, and dynamically adjust the operation state of the auxiliary heat dissipation circulation water circuit according to the real-time temperature change. Furthermore, when the water temperature in the water tank rises to a level that is not conducive to the auxiliary heat dissipation of the electronic ice tank, the pure water filtered by the composite filter element is delivered to the water tank to achieve a mixing operation of the pure water and the water with increased temperature in the water tank, thereby reducing the overall water temperature in the water tank to a certain extent, improving the flexibility and response speed of the water circuit optimization system, without manual intervention, improving the adaptability and intelligence level of the drinking water equipment, and improving the user experience;

[0027] 2. Through the structural design of the reflux circuit, before the refrigeration water circuit operates to output cold water, the residual water in the pipeline between the water outlet end of the fifth control valve and the water outlet nozzle on the electronic ice tank outlet pipeline can be refluxed to the water tank under the pressure of the booster pump. After the set reflux time is reached, the residual water in the pipeline has been completely refluxed, and then the subsequent refrigeration water circuit operation is performed, thereby avoiding the situation where the cold water output by the electronic ice tank after the refrigeration water circuit is operated is mixed with the residual water that has been heated in the pipeline, further ensuring that the user can obtain the required water temperature when taking cold water for the first time, thereby improving the user experience;

[0028] 3. Through the structural design of the water tank reflux passage and its control method, when the water temperature in the water tank begins to be higher than the water temperature on the heat dissipation water circuit component, that is, when the auxiliary heat dissipation circulation water circuit is no longer conducive to the auxiliary heat dissipation of the electronic ice tank, the auxiliary heat dissipation circulation water circuit is stopped, and the auxiliary cooling passage and the water tank reflux passage of the operating water tank are opened at the same time. Under the pressure of the booster pump, the purified water after the raw water inlet is filtered by the composite filter element is transported to the water tank through the auxiliary cooling passage of the water tank to achieve the mixing operation of the purified water and the water with increased temperature in the water tank, and the water with higher temperature at the bottom of the water tank flows out from the water outlet, and the purified water after the raw water inlet is mixed with the purified water after filtering through the water tank reflux passage and then flows back to the water tank after cooling. Therefore, without wasting water resources, the auxiliary cooling passage and the water tank reflux passage of the water tank are operated simultaneously to quickly reduce the overall water temperature in the water tank, further accelerate the cooling of the water in the water tank, and reach the temperature control opening condition of the auxiliary heat dissipation circulation water circuit more quickly;

[0029] 4. Through the structural design of the auxiliary heating passage, the water pump in the heat dissipation circulation water circuit is utilized to connect the water outlet of the water pump with the water inlet of the heater to form an auxiliary heating passage, and combined with the setting of the third temperature sensor on the heating water circuit and the first temperature sensor set in the water tank itself, when the refrigeration water circuit is operating, after the auxiliary heat dissipation circulation water circuit has been operating for a period of time, the water tank will continue to absorb the heat generated by the electronic ice tank, causing the water temperature in the water tank to gradually increase. Therefore, the present application cleverly utilizes this situation. When the drinking water equipment is in the process of making hot water and the water temperature in the water tank is higher than the water temperature of the pure water filtered by the composite filter element for the heating water circuit, the raw water supply passage of the heating water circuit is closed, and the water with higher water temperature in the water tank is used as the new water supply source for the heating water circuit, thereby dynamically adjusting the water supply source of the heating water circuit, which is more conducive to reducing the heating time of the pure water by the heater and improving the overall heating efficiency of the heating water circuit.

[0038] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

Therefore, it should not be understood as a limitation of the present invention.

[0040] Embodiment 1:

[0041] See also Figure 2 , Figure 2 A schematic diagram of the water path optimization system structure of a drinking water device provided in one embodiment of this specification.

[0042] like Figure 2 As shown, the water circuit optimization system of the drinking water equipment may at least include: a water tank 81, a water pump 82, an eighth control valve 83 and a heat dissipation water circuit assembly 84, wherein the water inlet of the water tank 81 is connected to the second water outlet end of the composite filter element to form an auxiliary cooling passage 7 of the water tank, and the auxiliary cooling passage 7 of the water tank is provided with a seventh control valve 71, the water outlet of the water tank 81 is connected to the water inlet end of the water pump 82, and the water outlet end of the water pump 82 is connected to the water inlet end of the heat dissipation water circuit assembly 84 via the eighth control valve 83, and the water outlet end of the heat dissipation water circuit assembly 84 is connected to the water inlet of the water tank 81, and a first temperature sensor 85 is provided in the water tank 81, and the water tank 81, the water pump 82, the eighth control valve 83 and the heat dissipation water circuit assembly 84 constitute an auxiliary heat dissipation circulating water circuit, and the heat dissipation water circuit assembly 84 is used to perform auxiliary heat dissipation on the electronic ice tank through the circulating water circuit, and a second temperature sensor 86 is provided on the heat dissipation water circuit assembly 84.

[0043] Specifically, the technical concept of this embodiment is: under the pressure of the water pump 82, the water in the water tank 81 flows out from the water outlet, flows through the water pump 82, the eighth control valve 83 and the heat dissipation water circuit component 84, and then flows back to the water tank 81 from the water inlet of the water tank 81, realizing the circulation of the water circuit, forming an auxiliary heat dissipation circulation water circuit. Through the circulation of water, the heat dissipation water circuit component 84 can effectively absorb the heat generated by the electronic ice chamber, accelerate the alternation of hot and cold of the electronic ice chamber, and evenly distribute the heat to the entire auxiliary heat dissipation circulation water circuit and the water tank 81, avoiding local overheating, improving the thermal stability of the system, and continuously assisting the electronic ice chamber. Heat dissipation, this design can achieve effective heat dissipation in a closed space, reduce the impact of the closed environment under the kitchen on the heat dissipation effect of the electronic ice tank, thereby quickly reducing the temperature of the electronic ice tank and improving the cooling efficiency of the entire under-kitchen drinking water equipment; combined with the setting of temperature sensors in the water tank 81 and on the heat dissipation water circuit assembly 84 and the structural design of the controllable auxiliary cooling passage of the water tank 81, when the water temperature in the water tank 81 rises to a level that is not conducive to the auxiliary heat dissipation of the electronic ice tank, the pure water filtered by the composite filter element is transported to the water tank 81 to achieve a mixing operation of the pure water and the water with increased temperature in the water tank 81, thereby reducing the overall water temperature in the water tank 81 to a certain extent.

[0044] It is understandable that the drinking water equipment is still supplied with raw water, and the water tank 81 in this embodiment is not used as a device for storing drinking water in the drinking water equipment, but as a key device for water circulation to assist the heat dissipation of the electronic ice tank. Further, the water tank 81 can be provided with a first water inlet and a second water inlet, the first water inlet of the water tank 81 is connected to the second water outlet of the composite filter element, and the second water inlet of the water tank 81 is connected to the water outlet of the heat dissipation water circuit assembly 84, thereby avoiding the adverse effect of the auxiliary cooling passage 7 of the water tank on the auxiliary heat dissipation circulation water circuit.

[0045] On the other hand, an embodiment of the present specification provides a control method for a water channel optimization system of a drinking water device, which may at least include the following steps:

[0046] During the operation of the refrigeration water circuit, the temperature values ​​of the first temperature sensor 85 and the second temperature sensor 86 are obtained in real time, and the temperature value of the first temperature sensor 85 is compared with the temperature value of the second temperature sensor 86;

[0047] When the temperature value of the first temperature sensor 85 is lower than the temperature value of the second temperature sensor 86, the eighth control valve 83 and the water pump 82 are controlled to open, and the auxiliary heat dissipation circulation water circuit is started;

[0048] When the temperature value of the first temperature sensor 85 is greater than or equal to the temperature value of the second temperature sensor 86 , the eighth control valve 83 and the water pump 82 are controlled to close, and the auxiliary heat dissipation circulation water circuit is stopped.

[0049] It can be understood that during the operation of the refrigeration water circuit, the first control valve, the booster pump, the fourth control valve, and the fifth control valve are all in the open state, so that the raw water flows through the refrigeration water circuit after being filtered by the composite filter element, and then the water is cooled by the electronic ice tank and flows out from the water outlet of the electronic ice tank to the water outlet nozzle, and the other control valves or pumps are in the closed state.

[0050] Specifically, the technical concept of this embodiment is: during the operation of the refrigeration water circuit, the temperature values ​​of the first temperature sensor 85 and the second temperature sensor 86 are obtained in real time, and the water temperature in the water tank 81 and the water temperature on the heat dissipation water circuit component 84 are compared in real time. When the refrigeration water circuit just starts to operate, the electronic ice bladder is performing heat dissipation refrigeration to reduce the water temperature. At this time, the water temperature on the heat dissipation water circuit component 84 absorbs the heat generated by the electronic ice bladder to a certain extent, so the water temperature in the water tank 81 is usually lower than the water temperature on the heat dissipation water circuit component 84. At this time, the temperature control opens the eighth control valve 83 and the water pump 82 to realize the circulation flow of the water circuit, and assists the heat dissipation circulation water circuit to start operation. Through the circulation of water, the heat dissipation water circuit component 84 effectively absorbs the heat generated by the electronic ice bladder, accelerating the cold and hot exchange of the electronic ice bladder. The auxiliary heat dissipation circulating water circuit is used to evenly distribute the heat to the entire auxiliary heat dissipation circulating water circuit and the water tank 81, and the electronic ice bladder is continuously cooled by the auxiliary heat dissipation circulating water circuit. After the auxiliary heat dissipation circulating water circuit has been in operation for a period of time, the water temperature in the water tank 81 gradually rises due to the continuous absorption of the heat generated by the electronic ice bladder, and the electronic ice bladder has achieved the heat dissipation and refrigeration effect with the help of the auxiliary heat dissipation circulating water circuit. At this time, the water temperature in the water tank 81 begins to be greater than the water temperature on the heat dissipation water circuit component 84, and the auxiliary heat dissipation circulating water circuit is no longer conducive to the auxiliary heat dissipation of the electronic ice bladder. At this time, the eighth control valve 83 and the water pump 82 are closed by temperature control to stop the circulation flow of the water circuit, and the auxiliary heat dissipation circulating water circuit stops operating until the water in the water tank 81 is naturally cooled during the operation of the refrigeration water circuit, and the temperature control opening condition of the auxiliary heat dissipation circulating water circuit is reached.

[0051] Furthermore, when the water temperature in the water tank 81 rises to a level that is not conducive to the auxiliary heat dissipation of the electronic ice chamber, the present embodiment can also deliver pure water filtered by the composite filter element to the water tank 81 to achieve a mixing operation of the pure water and the water with increased temperature in the water tank 81, thereby reducing the overall water temperature in the water tank 81 to a certain extent, accelerating the cooling of the water in the water tank 81, and more quickly reaching the temperature control opening condition of the auxiliary heat dissipation circulation water circuit.

[0052] Furthermore, before the operation of the refrigeration water circuit, that is, when the user touches the water outlet to take cold water, the present embodiment first determines whether the time interval from the last time the user took cold water is within a preset interval time (for example, it can be set to 5-10 minutes). If the interval time does not exceed the preset interval time, the refrigeration water circuit is directly started to operate, and the cold water in the electronic ice tank flows out to the water outlet after cooling by the electronic ice tank and heat dissipation by the auxiliary heat dissipation circulation water circuit; if the interval time exceeds the preset interval time, a countdown is displayed on the screen of the water outlet (the design of the present embodiment has greatly shortened the time for the electronic ice tank to cool water, so the countdown can be set to within 5s), thereby increasing the user's expectation of the time for taking water. After the countdown ends, the fifth control valve is controlled to open to allow cold water to flow out of the electronic ice tank, thereby further ensuring that the user obtains the required water temperature when taking cold water for the first time, thereby improving the user's experience.

[0053] This embodiment improves the flexibility and response speed of the water circuit optimization system by monitoring the water temperature in the water tank 81 and the water temperature on the heat dissipation water circuit assembly 84 in real time, and dynamically adjusts the operating state of the auxiliary heat dissipation circulation water circuit according to the real-time temperature changes, thereby ensuring effective auxiliary heat dissipation of the electronic ice cube in a closed environment under the kitchen without manual intervention, thereby improving the adaptability and intelligence level of the drinking water equipment and improving the user experience.

[0054] Embodiment 2:

[0055] See also Figure 3 , Figure 3 A schematic diagram of the structure of a water channel optimization system for drinking water equipment provided in yet another embodiment of the present specification.

[0056] This example only compares Figure 2 The corresponding added parts of the first embodiment are described, and the technical concept of the remaining structural design is similar to that of the first embodiment, which will not be repeated in this embodiment. Figure 3 As shown, the water path optimization system of the drinking water equipment also includes a reflux path 9, one end of the reflux path 9 is connected to the water outlet end of the fifth control valve, and the other end of the reflux path 9 is connected to the water outlet end of the first control valve. The reflux path 9 is used to realize the reflux of residual water in the pipeline under the pressure of the booster pump. A ninth control valve 91 is arranged on the reflux path 9, and the ninth control valve 91 is arranged close to the water outlet end of the fifth control valve.

[0057] Furthermore, a one-way valve may be provided on the reflux passage 9 to further avoid the adverse effects caused by the backflow of residual water in the pipeline.

[0058] It is understandable that in the non-refrigeration state of the drinking water equipment, there is no insulation measure for the residual water in the pipe between the electronic ice tank water outlet and the equipment water outlet, resulting in the water temperature of the residual water in the pipe between the electronic ice tank water outlet and the water outlet to increase due to the external ambient temperature.

[0059] Specifically, the technical concept of this embodiment is: connecting the pipeline between the water outlet end of the fifth control valve on the electronic ice tank water outlet pipeline and the water outlet nozzle to the reflux passage 9, and connecting the reflux passage 9 to the water outlet end of the first control valve through the ninth control valve 91, that is, connected to the water inlet end of the booster pump. Therefore, the reflux passage 9 can, under the pressure of the booster pump, return the residual water in the pipeline between the water outlet end of the fifth control valve on the electronic ice tank water outlet pipeline and the water outlet nozzle through the ninth control valve 91, the booster pump, the second water inlet end of the composite filter element (reverse osmosis membrane filtration unit), the second water outlet end of the composite filter element, and the auxiliary cooling passage 7 of the water tank to the water tank 81 in sequence, thereby avoiding the situation where the cold water output by the electronic ice tank after the operation of the refrigeration water circuit is mixed with the residual water that has been heated up in the pipeline, further ensuring that the user can obtain the required water temperature when taking cold water for the first time, thereby improving the user's experience.

[0060] On the other hand, another embodiment of the present specification provides a control method for a water channel optimization system of a drinking water device. Compared with the control method for a water channel optimization system of a drinking water device provided in the previous embodiment, this embodiment further includes the following steps before step 102:

[0061] Set the reflow time;

[0062] Control to open the seventh control valve 71, the ninth control valve 91 and the booster pump, and start the operation return path 9;

[0063] When the reflux time is reached, the seventh control valve 71 , the ninth control valve 91 and the booster pump are controlled to close, and the reflux passage 9 is stopped.

[0064] Among them, although the residual water in the pipeline between the water outlet end of the fifth control valve on the electronic ice tank water outlet pipeline and the water outlet nozzle will affect the water temperature of the user's first cup of cold water, the amount of residual water is usually not large, so the reflux time can also be set shorter. The specific reflux time can be set according to the actual length of the pipeline in the drinking water equipment or experience, and this embodiment does not limit this.

[0065] It is understandable that before the refrigeration water circuit operates, all control valves and pumps in the pipeline are in a closed state. Specifically, the technical concept of this embodiment is: before the refrigeration water circuit operates to output cold water, first control to open the seventh control valve 71, the ninth control valve 91 and the booster pump, start the operation of the reflux path 9, under the pressure of the booster pump, the residual water in the pipeline is sequentially returned to the water tank 81 through the ninth control valve 91, the booster pump, the second water inlet end of the composite filter element (reverse osmosis membrane filtration unit), the second water outlet end of the composite filter element, and the auxiliary cooling path 7 of the water tank, and when the set reflux time is reached, the residual water in the pipeline has been returned, and then step 102 is executed to perform the subsequent refrigeration water circuit operation, thereby avoiding the situation where the cold water output by the electronic ice tank after the refrigeration water circuit is operated is mixed with the residual water that has been heated in the pipeline, further ensuring that the user can obtain the required water temperature when taking cold water for the first time, and improving the user's experience.

[0066] Furthermore, in order to avoid the adverse effect of the residual water in the pipeline that has been heated up on the subsequent auxiliary heat dissipation of the water tank 81, before step 102, another implementation of this embodiment can be:

[0067] Set the reflow time;

[0068] Control to open the ninth control valve 91 and the booster pump, and start the operation return path 9;

[0069] When the reflux time is reached, the ninth control valve 91 and the booster pump are controlled to close, and the reflux passage 9 is stopped.

[0070] Specifically, under the control method of this embodiment, the seventh control valve 71 is kept closed during the backflow of the residual water in the pipeline, so that under the pressure of the booster pump, the residual water in the pipeline passes through the ninth control valve 91, the booster pump, and the second water inlet end of the composite filter element (reverse osmosis membrane filtration unit) in sequence, and is directly discharged from the wastewater discharge end of the composite filter element, thereby avoiding the adverse effects of the residual water that has been heated in the pipeline on the subsequent auxiliary heat dissipation of the water tank 81.

[0071] Embodiment three:

[0072] See also Figure 4 , Figure 4 A schematic diagram of the structure of a water channel optimization system for drinking water equipment provided in yet another embodiment of the present specification.

[0073] This example only compares Figure 3 The corresponding added parts of the second embodiment are described here, and the technical concept of the remaining structural design is similar to that of the second embodiment, which will not be repeated in this embodiment. Figure 4As shown, in the water channel optimization system of the drinking water equipment: the water outlet of the water tank 81 is connected to the reflux channel 9 to form the reflux channel 9 of the water tank 81, and the tenth control valve 92 is provided on the reflux channel 9 of the water tank 81.

[0074] It can be understood that in the reflux passage 9 of the water tank 81 of this embodiment, under the pressure of the booster pump, the water in the water tank 81 flows out from the water outlet, flows into the reflux passage 9 through the tenth control valve 92, passes through the booster pump and the second water inlet end (reverse osmosis membrane filtration unit) of the composite filter element, and then mixes with the pure water filtered by the raw water at the second water outlet end of the composite filter element and flows back to the water tank 81 through the auxiliary cooling passage 7 of the water tank, or flows into the second water inlet end (reverse osmosis membrane filtration unit) of the composite filter element and is directly discharged from the wastewater discharge end of the composite filter element, thereby reducing the water temperature in the water tank 81 and accelerating the cooling of the water in the water tank 81, so as to more quickly reach the temperature control opening condition of the auxiliary heat dissipation circulation water circuit.

[0075] On the other hand, another embodiment of the present specification provides a control method for a water circuit optimization system of a drinking water device. Compared with the control method for a water circuit optimization system of a drinking water device provided in the aforementioned embodiment, the present embodiment also includes: during the operation of the refrigeration water circuit, when the temperature value of the first temperature sensor 85 is greater than or equal to the temperature value of the second temperature sensor 86, the seventh control valve 71 and the tenth control valve 92 are controlled to be opened, and the auxiliary cooling passage 7 of the operating water tank and the reflux passage 9 of the water tank 81 are opened at the same time; when the temperature value of the first temperature sensor 85 is less than the temperature value of the second temperature sensor 86, the seventh control valve 71 and the tenth control valve 92 are controlled to be closed, and the auxiliary cooling passage 7 of the operating water tank and the reflux passage 9 of the water tank 81 are stopped at the same time.

[0076] It can be understood that during the operation of the refrigeration water circuit, the refrigeration water circuit is connected and the booster pump is in the open state, so that the raw water flows through the refrigeration water circuit after being filtered by the composite filter element, and then the water is cooled by the electronic ice tank and flows out from the water outlet of the electronic ice tank to the water outlet nozzle, and the other control valves or pumps are in the closed state.

[0077] Specifically, the technical concept of this embodiment is: when the water temperature in the water tank 81 is lower than the water temperature on the heat dissipation water circuit component 84, the temperature control opens the eighth control valve 83 and the water pump 82 to realize the circulation flow of the water circuit, and the auxiliary heat dissipation circulation water circuit is started and operated. Through the circulation flow of water, the heat dissipation water circuit component 84 effectively absorbs the heat generated by the electronic ice gallbladder, accelerates the alternation of hot and cold of the electronic ice gallbladder, and evenly distributes the heat to the entire auxiliary heat dissipation circulation water circuit and the water tank 81, and continuously assists in the heat dissipation of the electronic ice gallbladder. After the auxiliary heat dissipation circulation water circuit has been operating for a period of time, the water temperature in the water tank 81 gradually increases due to the continuous absorption of the heat generated by the electronic ice gallbladder, and the electronic ice gallbladder has achieved the heat dissipation and refrigeration effect with the help of the auxiliary heat dissipation circulation water circuit. At this time, the water temperature in the water tank 81 begins to be higher than the water temperature on the heat dissipation water circuit component 84, and the auxiliary heat dissipation circulation water circuit is no longer conducive to the auxiliary heat dissipation of the electronic ice gallbladder. At this time, the temperature control closes the eighth control valve 83. The control valve 83 and the water pump 82 stop the circulation of the water circuit, and the auxiliary heat dissipation circulation water circuit stops operating. At this time, the seventh control valve 71 and the tenth control valve 92 are opened, and the auxiliary cooling passage 7 of the operating water tank and the return passage 9 of the water tank 81 are opened at the same time. Under the pressure of the booster pump, the pure water after the raw water inlet is filtered by the composite filter element is transported to the water tank 81 through the auxiliary cooling passage 7 of the water tank to achieve the mixing operation of the pure water and the water with increased temperature in the water tank 81. At the same time, the water with higher temperature at the bottom of the water tank 81 flows out from the water outlet, is mixed with the pure water after the raw water inlet is filtered through the return passage 9 of the water tank 81, and then flows back to the water tank 81 after cooling. Therefore, without wasting water resources, the auxiliary cooling passage 7 of the water tank and the return passage 9 of the water tank 81 are operated simultaneously to quickly reduce the overall water temperature in the water tank 81, further accelerate the cooling of the water in the water tank 81, and more quickly reach the temperature control opening condition of the auxiliary heat dissipation circulation water circuit.

[0078] Embodiment 4:

[0079] See also Figure 5 , Figure 5 A schematic diagram of the structure of a water channel optimization system for drinking water equipment provided in yet another embodiment of the present specification.

[0080] This example only compares Figure 4 The corresponding added parts of the third embodiment are described here, and the technical concept of the remaining structural design is similar to that of the third embodiment, which will not be repeated in this embodiment. Figure 5 As shown, the water path optimization system of the drinking water equipment also includes: the water outlet end of the water pump 82 is connected to the water inlet end of the heater to form an auxiliary heating path, an eleventh control valve 10 is provided on the auxiliary heating path, and a third temperature sensor 33 is provided on the heating water path, and the third temperature sensor 33 is located before the connection point between the auxiliary heating path and the water outlet end of the water pump 82.

[0081] Among them, the third temperature sensor 33 is located before the connection point between the auxiliary heating passage and the water outlet end of the water pump 82, indicating that the third temperature sensor 33 is used to detect the water temperature of the filtered pure water when it just enters the heating water path but has not yet been heated by the heater.

[0082] It can be understood that, in the aforementioned embodiment, it is known that the water in the water tank 81 is pure water filtered by a filter element. This embodiment utilizes a water pump 82 in the heat dissipation circulation water circuit, and connects the water outlet of the water pump 82 to the water inlet of the heater to form an auxiliary heating circuit, and combines the setting of the third temperature sensor 33 on the heating water circuit and the first temperature sensor 85 set in the water tank 81. When the drinking water equipment is in the process of making hot water and the water temperature in the water tank 81 is higher than the water temperature of the pure water filtered by the composite filter element for the heating water circuit, the pure water filtered by the composite filter element is stopped from supplying water to the heater, and the pure water with a higher temperature in the water tank 81 is used as the water supply to the heater, which is more conducive to reducing the heating time of the heater for the pure water and improving the overall heating efficiency of the heating water circuit.

[0083] On the other hand, another embodiment of the present specification provides a control method for a water channel optimization system of a drinking water device. Compared with the control method for a water channel optimization system of a drinking water device provided in the previous embodiment, this embodiment further includes the following steps:

[0084] During the operation of the heating water circuit, the temperature values ​​of the first temperature sensor 85 and the third temperature sensor 33 are obtained in real time, and the temperature value of the first temperature sensor 85 is compared with the temperature value of the third temperature sensor 33;

[0085] When the temperature value of the first temperature sensor 85 is greater than the temperature value of the second temperature sensor 86, the third control valve is controlled to be closed, the eleventh control valve 10 and the water pump 82 are opened, and the auxiliary heating path is started;

[0086] When the temperature value of the first temperature sensor 85 is less than or equal to the temperature value of the third temperature sensor 33 , the third control valve is controlled to open, the eleventh control valve 10 and the water pump 82 are closed, and the auxiliary heating path is stopped.

[0087] It can be understood that during the operation of the heating water circuit, the first control valve, the booster pump, and the third control valve are all in the open state, so that the raw water flows through the heating water circuit after being filtered by the composite filter element, and then the water is heated by the heater and flows out from the water outlet end of the heater to the water outlet nozzle, and the other control valves or pumps are all in the closed state.

[0088] Specifically, the technical concept of this embodiment is: in the operation process of the heating water circuit, the temperature values ​​of the first temperature sensor 85 and the third temperature sensor 33 are obtained in real time, and the water temperature in the water tank 81 and the water supply temperature on the heating water circuit are compared in real time. When the cooling water circuit is in operation, after the auxiliary heat dissipation circulation water circuit has been in operation for a period of time, the water tank 81 will continue to absorb the heat generated by the electronic ice tank, causing the water temperature in the water tank 81 to gradually increase. Therefore, this embodiment cleverly uses this situation. When the water temperature in the water tank 81 is higher than the water supply temperature on the heating water circuit, the third control valve is controlled to be closed, that is, Close the raw water supply passage of the heating water circuit, open the eleventh control valve 10 and the water pump 82, start the operation of the auxiliary heating passage, and under the pressure of the water pump 82, use the water with higher water temperature in the water tank 81 as the new water supply source for the heating water circuit, which is more conducive to reducing the heating time of the heater for the pure water and improving the overall heating efficiency of the heating water circuit. Until the water in the water tank 81 cools down naturally during the operation of the heating water circuit and the water temperature is no longer conducive to the auxiliary heating of the heating water circuit compared to the raw water supply, stop the operation of the auxiliary heating passage and instead open the raw water supply passage of the heating water circuit.

[0089] Furthermore, considering that the water tank 81 may be short of water during drainage or water supply to the heating water circuit, the following steps may be further included in the embodiments of the present disclosure:

[0090] During the operation of the water tank 81, the water level of the water tank 81 is obtained in real time. When the water level reaches the preset lower limit of the water level, the corresponding control valve (such as the tenth control valve 92 or the eleventh control valve 10) is controlled to close to stop the water outflow of the water tank 81, and the seventh control valve 71 is opened to replenish water to the water tank 81.

[0091] Furthermore, in this embodiment, if Figure 5 As shown, the water channel optimization system of the drinking water equipment may further include: the water outlet end of the sixth control valve is connected to the reflux channel 9 to form the electronic ice tank reflux channel 9.

[0092] It can be understood that, through the setting of the electronic ice tank reflux passage 9, the cold water in the electronic ice tank can be discharged periodically, which can not only ensure the water safety of the user, but also because the setting of the electronic ice tank reflux passage 9 allows the water discharged from the electronic ice tank to flow through the reflux passage 9, the second water inlet end of the composite filter element (reverse osmosis membrane filtration unit), and the auxiliary cooling passage 7 of the water tank under the pressure of the booster pump, and then flow back to the water tank 81, thereby reducing the water temperature in the water tank 81 to a certain extent, so that when the auxiliary heat dissipation circulation water circuit is operating, water circulation heat dissipation can be carried out at a lower water temperature, which helps to improve the overall refrigeration efficiency of the drinking water equipment to a certain extent.

[0093] Embodiment five:

[0094] See also Figure 6 , Figure 6 This is a schematic diagram of the structure of a heat dissipation water channel assembly 84 in an electronic ice container provided in yet another embodiment of the present specification.

[0095] This example only compares Figure 2 The corresponding added parts of the first embodiment are described, and the technical concept of the remaining structural design is similar to that of the first embodiment, which will not be repeated in this embodiment. Figure 6 As shown, in the water circuit optimization system of the drinking water equipment: the heat dissipation water circuit component 84 includes a hot water absorption pipe 841 and a heat absorption seat 842, the hot water absorption pipe 841 and the heat absorption seat 842 are integrally formed, the hot water absorption pipe 841 is bent and arranged in the heat absorption seat 842 to maximize the pipe length of the hot water absorption pipe 841 in the heat absorption seat 842 and the contact surface between the hot water absorption pipe 841 and the heat absorption seat 842, the heat absorption surface of the heat absorption seat 842 matches the heat sink, and the heat absorption seat 842 is located between the electronic ice tank 81 and the heat sink.

[0096] It is understandable that, since the heat absorption pipe 841 and the heat absorption seat 842 are integrally formed, the water inlet end of the heat absorption pipe 841 is the water inlet end of the heat dissipation water circuit assembly 84 , and the water outlet end of the heat absorption pipe 841 is the water outlet end of the heat dissipation water circuit assembly 84 .

[0097] In this embodiment, the heat dissipation water circuit assembly 84 is designed in a structure. Specifically, the heat absorption pipe 841 is bent and arranged in the heat absorption seat 842 to maximize the pipe length of the heat absorption pipe 841 in the heat absorption seat 842 and the contact surface between the heat absorption pipe 841 and the heat absorption seat 842. The heat exchange area between the water in the heat absorption pipe 841 and the heat absorption seat 842 and the heat sink of the electronic ice bladder can be greatly increased, which helps to achieve faster heat dissipation of the electronic ice bladder water tank 81, accelerate heat exchange, and combine the heat absorption surface of the heat absorption seat 842 with the heat dissipation. The matching structural design of the sheets helps to evenly distribute the absorbed heat to the heat sink, avoiding local overheating, improving the overall heat dissipation efficiency of the electronic ice tank to a certain extent, and at the same time improves the heat dissipation effect of the auxiliary heat dissipation circulation water path on the electronic ice tank, and the heat absorption seat 842 is clamped between the electronic ice tank water tank 81 and the heat sink, providing a stable supporting structure for the heat dissipation water path assembly 84, helping to reduce the relative displacement between the components of the heat dissipation water path assembly 84 caused by vibration or movement, and improving the stability of the overall structure of the heat dissipation water path assembly 84.

[0098] Furthermore, in a non-refrigeration state, the water temperature in the electronic ice container is easily increased due to the external environment temperature. Therefore, in this embodiment, a heat preservation device may be provided outside the electronic ice container water tank 81.
