[0001] This application relates to the field of waterway system technology, and in particular to a waterway system. Background Technology

[0002] As people's living standards improve, their requirements for drinking water quality are also increasing. Water purifiers have become the choice of most families, filtering tap water to achieve the water quality required by users. Furthermore, current water purifiers also have heating and cooling functions to meet diverse user needs.

[0003] In related technologies, current water purifiers use a compressor refrigeration system to cool the filtered pure water. However, the method of dispensing water by cooling it with a compressor still involves pre-storing room-temperature pure water in a storage container, then using the compressor to cool and store the water in the storage container through heat exchange with an evaporator. When the user wants to drink the water, the cold water in the storage tank is then delivered to the machine's outlet.

[0004] However, since pure water is stored in water containers for a long time, the length of storage time and whether the water containers are cleaned and maintained regularly may lead to secondary pollution problems. Utility Model Content

[0005] Based on this, this application provides a water system to solve the problem of secondary pollution in water systems in related technologies.

[0006] This application provides a water system comprising: a filter element; a cold water assembly including a cold water pipe, a cold water outlet pipe, and an energy storage chamber, wherein the cold water pipe passes through the energy storage chamber; the outlet of the filter element is connected to the inlet of the cold water pipe, and the outlet of the cold water pipe is connected to the inlet of the cold water outlet pipe; a heat exchange medium is provided in the energy storage chamber; and a refrigeration assembly including a refrigeration pipe and an evaporator, wherein the evaporator is disposed in the refrigeration pipe; the refrigeration pipe passes through the energy storage chamber, the evaporator is located in the energy storage chamber, and a flowable cooling medium is provided in the refrigeration pipe.

[0007] In one embodiment, the cold water assembly further includes a first temperature sensor disposed in the cold water outlet pipe and located downstream of the energy storage compartment.

[0008] In one embodiment, the water system further includes a water pump, which is located in the connecting pipe between the filter element and the cold water pipe and upstream of the first temperature measuring element. The water pump can adjust the flow rate in the cold water pipe according to the detection data of the first temperature measuring element, so as to adjust the temperature of the outlet of the cold water outlet pipe.

[0009] In one embodiment, the water system also includes a negative pressure switch, which is disposed in the connecting pipe between the filter element and the cold water pipe and is located upstream of the water pump. The negative pressure switch can adjust its opening degree according to the output power of the water pump.

[0010] In one embodiment, the water system further includes a normal temperature water outlet pipe, the outlet of the filter element is connected to the inlet of the normal temperature water outlet pipe, and a second one-way valve is provided on the normal temperature water outlet pipe.

[0011] In one embodiment, the water system further includes a distributor, wherein the outlet of the filter element is connected to a first distribution inlet of the distributor, and the first distribution outlet of the distributor is connected to the inlet of the cold water pipe; the filter element includes a pre-filter and a fine filter, and the water system further includes a booster pump and an inlet valve; the inlet of the pre-filter is connected to the raw water, the outlet of the pre-filter is connected to a second distribution inlet of the distributor, the inlet valve is located in the connecting pipeline between the pre-filter and the distributor, the second distribution outlet of the distributor is connected to the inlet of the fine filter, the booster pump is located in the connecting pipeline between the distributor and the fine filter, and the outlet of the fine filter is connected to the inlet of the cold water pipe; and / or, the filter element further includes a post-filter, wherein the outlet of the fine filter is connected to the inlet of the post-filter, and the outlet of the post-filter is connected to the inlet of the cold water pipe.

[0012] In one embodiment, the water system further includes a water distribution pipe, a reversing valve, a heated water outlet pipe, and a heating element, wherein the heating element is disposed in the heated water outlet pipe; the inlet of the water distribution pipe is connected to the outlet of the filter element, the outlet of the water distribution pipe is connected to the inlet of the reversing valve, the first reversing outlet of the reversing valve is connected to the inlet of the cold water pipe, and the second reversing outlet of the reversing valve is connected to the inlet of the heated water outlet pipe.

[0013] In one embodiment, the cold water assembly further includes a first check valve, which is disposed in the cold water outlet pipe and located downstream of the first temperature sensor.

[0014] In one embodiment, the refrigeration assembly further includes a circulation pump and a circulation pipeline, with the circulation pump disposed on the circulation pipeline; both ends of the circulation pipeline are respectively connected to the energy storage compartment, and the two ends of the circulation pipeline are spaced apart along the height direction of the energy storage compartment.

[0015] In one embodiment, the cold water pipe includes a spiral pipe.

[0016] The technical solution of this application introduces water into a filter element, which filters the raw water. The filtered water then enters a cold water pipe. Since the cold water pipe passes through an energy storage chamber, and the evaporator is located within the energy storage chamber, which contains a heat exchange medium, and the refrigeration pipe contains a cooling medium, the cooling medium in the refrigeration pipe can exchange heat with the heat exchange medium, absorbing its heat and cooling it. Simultaneously, the heat exchange medium can exchange heat with the water in the cold water pipe, absorbing its heat and cooling it. The water after heat exchange then flows through the cold water outlet pipe to obtain cold water. Compared to related technologies that store water in a storage container for extended periods, the water system of this application cools both the heat exchange medium and the pure water using the cooling medium. Therefore, water only needs to flow in the cold water pipe, eliminating the need for a storage container to provide immediate cold water and avoiding secondary contamination issues associated with water storage containers.

[0026] See Figure 1 , Figure 1 This illustration shows a piping diagram of a water system provided in an embodiment of this application. One embodiment of this application provides a water system including a filter element 10, a cold water assembly 20, and a refrigeration assembly 30. The cold water assembly 20 includes a cold water pipe 21, a cold water outlet pipe 27, and an energy storage chamber 22. The cold water pipe 21 passes through the energy storage chamber 22. The inlet of the cold water pipe 21 is connected to the outlet of the filter element 10, and the outlet of the cold water pipe 21 is connected to the inlet of the cold water outlet pipe 27. A heat exchange medium is disposed within the energy storage chamber 22. The refrigeration assembly 30 includes a refrigeration pipe 31 and an evaporator 32. The evaporator 32 is disposed within the refrigeration pipe 31. The evaporator 32 is located within the energy storage chamber 22, and the refrigeration pipe 31 passes through the energy storage chamber, containing a flowable cooling medium.

[0027] Using the technical solution of this application, water is introduced into the filter element 10, and the filter element 10 is used to filter the raw water. The filtered water then enters the cold water pipe 21. Since the cold water pipe 21 passes through the energy storage chamber 22, the evaporator 32 is located inside the energy storage chamber 22, and the energy storage chamber 22 contains a heat exchange medium, while the refrigeration pipe 31 contains a cooling medium, the cooling medium in the refrigeration pipe 31 can exchange heat with the heat exchange medium, thereby absorbing the heat from the heat exchange medium and cooling it down. At the same time, the heat exchange medium can exchange heat with the water in the cold water pipe 21, absorbing the heat from the water and cooling it down. The water after heat exchange can be cooled through the cold water outlet pipe 27. Compared to related technologies that store water in a storage container for a long time, the water system of this application cools the heat exchange medium and the water through the cooling medium. Thus, water only needs to flow in the cold water pipe 21, eliminating the need for a dedicated storage container for cold water as in related technologies. This allows for immediate access to cold water and avoids the problem of secondary pollution of water in a storage container.

[0028] The heat exchange medium in the energy storage chamber 22 can be low-temperature water or other media. In order to ensure that the water temperature at the outlet of the cold water outlet pipe 27 meets the requirements, both the cold water pipe 21 and the evaporator 32 should be completely immersed in the heat exchange medium.

[0029] In some embodiments, in order to increase the contact area between the cold water pipe 21 and the heat exchange medium, the cold water pipe 21 may be configured as a spiral pipe or the like.

[0030] It should be noted that in order to ensure that cold water is always available at the outlet of the cold water outlet pipe 27, the evaporator 32 needs to be in a working state or in an intermittent working state, and the cooling medium in the evaporator 32 needs to be able to absorb heat from the heat exchange medium at all times.

[0031] Combination Figure 1 As shown, the chilled water assembly 20 also includes a first temperature measuring element 23, which is disposed in the chilled water outlet pipe 27 and located downstream of the energy storage chamber 22. The first temperature measuring element 23 can measure the water temperature in the chilled water outlet pipe 27 to determine whether the water temperature at the outlet of the chilled water outlet pipe 27 meets the requirements.

[0032] In some embodiments, the first temperature sensing element 23 is a thermistor. Of course, other types of temperature sensing elements can also be used as the first temperature sensing element. Using a thermistor has the advantages of fast response speed and low cost.

[0033] Combination Figure 1 As shown, the water system also includes a water pump 24, which is located in the connecting pipe between the filter element 10 and the cold water pipe 21 and upstream of the first temperature measuring element 23. The water pump 24 can adjust the flow rate in the cold water pipe 21 according to the detection data of the first temperature measuring element 23, thereby adjusting the temperature of the outlet of the cold water outlet pipe 27. With the above design, after the first temperature measuring element 23 detects the temperature of the cold water, if the temperature of the cold water cannot meet the requirements, the output power of the water pump 24 can be adjusted, thereby adjusting the flow rate in the cold water pipe 21. Under the condition that the heat exchange between the heat exchange medium and the cold water remains unchanged, the temperature of the outlet of the cold water outlet pipe 27 can be adjusted.

[0034] Combination Figure 1 As shown, the water system also includes a negative pressure switch 25, which is located in the connecting pipe between the filter element 10 and the cold water pipe 21, upstream of the water pump 24. The negative pressure switch 25 can adjust its opening degree according to the output power of the water pump 24. The negative pressure generated by the water pump 24 can open the negative pressure switch 25, thereby drawing water into the cold water pipe 21. After the water pump 24 stops working, the negative pressure switch 25 is in the closed state due to the disappearance of the negative pressure.

[0035] Specifically, when the output power of the water pump 24 increases, the opening degree of the negative pressure switch 25 is increased. When the output power of the water pump 24 decreases, the opening degree of the negative pressure switch 25 is decreased.

[0036] Combination Figure 1As shown, the water system also includes a room temperature water outlet pipe 40, and the outlet of the filter element 10 is connected to the inlet of the room temperature water outlet pipe 40. By setting up the room temperature water outlet pipe 40, users can conveniently drink room temperature water immediately.

[0037] In some embodiments, the outlet of the ambient temperature water outlet pipe 40 and the outlet of the cold water outlet pipe 27 are both connected to a water tap. The cold water assembly 20 also includes a first check valve 26, which is disposed in the cold water outlet pipe 27 and located downstream of the first temperature measuring element 23. The first check valve 26 can prevent backflow of cold water in the cold water pipe 21. The water system also includes a second check valve 43, which is disposed in the ambient temperature water outlet pipe 40 and can prevent backflow of ambient temperature water in the ambient temperature water outlet pipe 40.

[0038] Among them, a solenoid valve is also installed on the normal temperature water outlet pipe 40. The solenoid valve is located upstream of the second one-way valve 43 and controls the opening and closing of the normal temperature water outlet pipe 40.

[0039] Combination Figure 1 As shown, the water system also includes a distributor 60. The outlet of the filter element is connected to the first distribution inlet 61 of the distributor 60, and the first distribution outlet 62 of the distributor 60 is connected to the inlet of the cold water pipe 21. The filter element 10 includes a pre-filter, a fine filter, and a post-filter. The water system also includes a booster pump 90 and an inlet valve 70. The inlet of the pre-filter is connected to the raw water, and the outlet of the pre-filter is connected to the second distribution inlet 63 of the distributor 60. The inlet valve 70 is located in the connecting pipe between the pre-filter and the distributor 60. The second distribution outlet 64 of the distributor 60 is connected to the inlet of the fine filter. The booster pump 90 is located in the connecting pipe between the distributor 60 and the fine filter. The outlet of the fine filter is connected to the inlet of the cold water pipe 21. With the above design, when the water demand at the outlet of the post-filter is less than the pure water provided by the fine filter, the excess pure water can flow back to the front of the fine filter. This avoids excessive back pressure on the booster pump 90 due to excessive water pressure at the outlet of the fine filter, which would increase the noise during the operation of the water system and also avoid other adverse effects on the reliability of the water system.

[0040] The cold water outlet 27 and the heating water outlet 110 require relatively small amounts of water, so the water flow at the fine filter outlet will reach its maximum, which in turn increases the back pressure of the booster pump 90. By operating the booster pump 90, excess pure water can be returned to the fine filter to reduce the back pressure during the operation of the booster pump 90.

[0041] In some embodiments, the filter element further includes a post-filter element, the outlet of the fine filter element is connected to the inlet of the post-filter element, and the outlet of the post-filter element is connected to the inlet of the cold water pipe 21.

[0042] In some embodiments, filter element 10 is a composite filter element, which includes at least one of a pre-filter and a post-filter, as well as a reverse osmosis membrane. Both the pre-filter and post-filter can be activated carbon filters. The activated carbon is made from high-quality fruit shell charcoal and coal-based activated carbon, supplemented with food-grade binders, and processed using high-tech techniques and special processes. It is mainly used to adsorb residual chlorine, discoloration, and odors in water. The reverse osmosis membrane has a filtration accuracy of 0.0001μm, which can intercept almost all impurities in the water, including bacteria, viruses, and heavy metal ions, allowing only water molecules to pass through. The filtered water is safe to drink directly.

[0043] In this embodiment, the filter element 10 includes a pre-filter, a fine filter, and a post-filter. The pre-filter, fine filter, and post-filter are combined in the same filter bottle to form a composite filter element. The filter element 10 has five inlets: a first inlet 11 for raw water to enter, a first outlet 14 for water to exit and flow to the inlet valve 70, a second inlet 13 for purified water after passing through the pre-filter, a second outlet 12 for pure water to flow out, and a wastewater outlet 15 for wastewater to be discharged.

[0044] In some embodiments, filter element 10 includes a pre-filter, a fine filter, and a post-filter. The pre-filter, fine filter, and post-filter may be partially combined, partially separate, or all separately arranged. Alternatively, the filter element may include some of the aforementioned filter elements, or it may include other types of filter elements. The specific choice depends on actual needs.

[0045] Combination Figure 1 As shown, the water system also includes a distribution pipe 100, a reversing valve 80, a heated water outlet pipe 110, and a heating element 111, which is installed in the heated water outlet pipe 110. The inlet of the distribution pipe 100 is connected to the outlet of the filter element 10, the outlet of the distribution pipe 100 is connected to the inlet of the reversing valve 80, the first reversing outlet of the reversing valve 80 is connected to the inlet of the cold water pipe 21, and the second reversing outlet of the reversing valve 80 is connected to the inlet of the heated water outlet pipe. With the above design, the heating element 111 can heat the water in the heated water outlet pipe 110, allowing users to obtain hot water for immediate drinking.

[0046] Through the water system of this application, users can obtain room temperature drinking water immediately via the room temperature water outlet pipe 40, obtain cold drinking water immediately via the cold water pipe 21, energy storage chamber 22 and refrigeration component 30, and obtain hot drinking water immediately via the heating element 111 and heated water outlet pipe 110. Thus, the needs of different groups of people can be met.

[0047] In some embodiments, both the negative pressure switch 25 and the water pump 24 are located in the water distribution pipe 100. Whether the user needs to drink cold water or hot water, they can start the water pump 24 and use the negative pressure generated by the water pump 24 to open the negative pressure switch 25.

[0048] The water distribution pipeline 100 is located downstream of the distribution component 60, and the first distribution outlet of the distribution component 60 is connected to the water inlet of the water distribution pipeline 100.

[0049] In some embodiments, the outlet of the heating water outlet pipe 110 is directly connected to the water tap. In other embodiments, the outlet of the heating water outlet pipe 110 can also be connected to a manifold, which connects to the water tap. In this case, a one-way valve also needs to be designed on the heating water outlet pipe 110.

[0050] The water distribution pipe 100 is equipped with a reversing valve, which enables the water distribution pipe 100 to be connected to only one of the cold water pipe 21 and the heated water outlet pipe 110.

[0051] Combination Figure 1 As shown, the refrigeration assembly 30 also includes a compressor 33 and a condenser 34, and the evaporator 32 is an evaporator. The evaporator, compressor 33, and condenser 34 are sequentially arranged in the refrigeration pipeline 31. Utilizing existing mature refrigeration technology, heat exchange occurs between the cooling medium and the heat exchange medium, which has the advantages of mature technology and low cost.

[0052] The general refrigeration component 30 also includes a capillary tube 37, which is located downstream of the condenser 34. The capillary tube 37 can regulate the flow rate of the cooling medium and reduce the pressure of the cooling medium. This allows the cooling medium to absorb heat from the water and change from a liquid to a gaseous state after entering the evaporator.

[0053] Specifically, the cooling medium in the evaporator evaporates and absorbs heat in the energy storage chamber 22, thereby cooling the heat exchange medium in the energy storage chamber 22. After absorbing heat, the cooling medium changes from liquid to gas. The gaseous cooling medium is compressed in the compressor 33, thus becoming a high-temperature, high-pressure gas. It then passes through the condenser 34 and condenses there, transforming the high-temperature, high-pressure gas into a high-temperature, high-pressure liquid. Finally, it passes through a capillary tube, transforming into a low-temperature, low-pressure liquid, and then enters the evaporator for circulation.

[0054] In some embodiments, in order to ensure that the outlet of the cold water outlet pipe 27 always receives cold water immediately, the compressor 33 operates intermittently to control the cold water in the cold water pipe 21 within a certain temperature range.

[0055] The condenser 34 can be cooled by air, such as by a fan, or by liquid cooling.

[0056] Combination Figure 1 As shown, the refrigeration assembly 30 also includes a circulation pump 35 and a circulation pipeline 36, with the circulation pump 35 disposed within the circulation pipeline 36. Both ends of the circulation pipeline 36 are connected to the energy storage chamber 22, and the two ends of the circulation pipeline 36 are spaced apart along the height direction of the energy storage chamber 22. Using this design, the circulation pump 35 pumps water from the lower part of the energy storage chamber 22 into the circulation pipeline 36, and then transports the water to the upper part of the energy storage chamber 22 through the circulation pipeline 36, thereby achieving heat exchange of the water within the energy storage chamber 22, preventing excessive local cooling, and thus preventing the energy storage chamber 22 from freezing.

[0057] In some embodiments, the energy storage chamber 22 is further provided with a second temperature measuring element 221. The second temperature measuring element 221 can detect the water temperature inside the energy storage chamber 22, ensuring that the water temperature at the outlet of the cold water outlet pipe 27 meets the requirements. On the other hand, the second temperature measuring element 221 can be placed in areas of the energy storage chamber 22 prone to freezing, thereby monitoring the temperature there. Of course, temperature measuring elements can also be installed in different locations according to actual needs.

[0058] Combination Figure 1 As shown, the water system also includes a wastewater pipe 120, the inlet of which is connected to the wastewater outlet 15 of the filter element 10. The wastewater generated after filtration by the filter element 10 can be discharged through the wastewater pipe 120.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
