Description

Technical Field

[0001] This invention relates to the field of pipeline water dispenser technology, and in particular to a wall-mounted pipeline water dispenser. Background Technology

[0002] A piped water dispenser, also known as a piped water purifier, comes in wall-mounted and floor-standing models and is typically used in homes and offices. Traditional piped water dispensers only have one function: heating or cooling, which cannot meet users' simultaneous needs for both cold and hot water. With rising living standards and technological advancements, people have increasingly higher demands for drinking water quality, and multifunctional, integrated products are gaining popularity among consumers.

[0003] Existing technologies already include several multi-functional integrated pipeline water dispensers. For example, utility model patent CN220442482U discloses an embedded pipeline water dispenser with a rapid cooling and heating system. This includes a main body, which is equipped with a filtration mechanism, a rapid heating device, and a rapid cooling device. The rapid cooling device includes a heating end and a cooling end. The purified water outlet of the filtration mechanism is connected to a water storage tank. The first outlet of the water storage tank is connected to the rapid heating device, and the second outlet of the water storage tank is connected to the cooling end of the rapid cooling device. The wastewater outlet of the filtration mechanism is connected to the heating end of the rapid cooling device, and the cooling end is connected to a downstream outlet structure of the rapid heating device. A TDS detection module is connected between the filtration mechanism and the water storage tank. This utility model has the following advantages and effects: This solution utilizes a new mechanical structure, achieving the combined effects of cold and hot water preparation, good cooling effect, low noise, and wastewater utilization.

[0004] However, in order to meet the requirements of small size and multiple functions, existing wall-mounted piped water dispensers mainly use semiconductor refrigeration for cooling (semiconductor refrigeration water dispensers contain cooling chips made of special semiconductor materials. When current passes through these semiconductor particles, heat is transferred from one side of the particles to the other, thereby achieving a cooling effect). This cooling method is less effective than compressor refrigeration. However, compressor refrigeration requires equipment such as compressors, condensers, expansion valves, and evaporators, which will greatly increase the size of the wall-mounted piped water dispenser, making it unsuitable for small spaces. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the technical problem solved by the present invention is: how to improve the cooling effect of the wall-mounted pipeline water dispenser without increasing the volume.

[0006] To achieve the above objectives, in a first aspect, the wall-mounted piped water dispenser provided by the present invention includes a water storage tank, a refrigeration device, and a heating device, characterized in that the refrigeration device includes:

[0007] Refrigeration housing;

[0008] The refrigeration pipeline is located inside the refrigeration housing. One end of the refrigeration pipeline is connected to the water storage tank through the first water inlet pipeline, and the other end is connected to the water outlet of the wall-mounted pipeline water dispenser through the first water outlet pipeline.

[0009] The circulating water circuit is arranged around the refrigeration pipes along the direction of water flow.

[0010] A semiconductor cooling component is mounted on a cooling housing to cool the cooling pipes and circulating water circuit.

[0011] By adopting the above technical solution, when the semiconductor refrigeration component cools the refrigeration pipes, the drinking water flowing into the refrigeration pipes cools down due to the temperature drop of the refrigeration pipes. At the same time, the semiconductor refrigeration component cools the circulating water circuit, causing the temperature of the circulating water flowing inside the circulating water circuit to drop. Since the length of the circulating water circuit is much greater than the length of the refrigeration pipes, the cooling time of the circulating water is longer to reach a lower temperature. Therefore, the circulating water can further cool the refrigeration pipes, increasing the cooling rate of the drinking water, thereby improving the cooling effect of the wall-mounted pipeline water dispenser without increasing the volume.

[0012] In conjunction with the first aspect, in one embodiment, the cooling pipeline is a U-shaped pipeline, the starting point of the circulating water path is the connection point between the cooling pipeline and the first water inlet pipeline, one end of the circulating water path is provided with a second water inlet pipeline, and part of the second water inlet pipeline is located inside the cooling housing, so as to realize the semiconductor cooling component to cool the second water inlet pipeline.

[0013] By adopting the above technical solution, not only the refrigeration pipes and circulating water circuits are cooled, but also the second water inlet pipe is cooled, thereby increasing the cooling time of the circulating water and further improving the cooling effect of the wall-mounted water dispenser.

[0014] In one embodiment, a first booster pump is provided between the refrigeration pipeline and the first water outlet pipeline to enable drinking water to flow out from the outlet.

[0015] By adopting the above technical solution, the flow rate of drinking water passing through the U-shaped pipeline is increased, thereby improving the water output efficiency of the wall-mounted pipeline water dispenser.

[0016] In one embodiment, the heating device includes a third inlet pipe, a second booster pump, a heating pipe, and a third outlet pipe. The inlet end of the second booster pump is connected to the water storage tank through the third inlet pipe, the outlet end of the second booster pump is connected to one end of the heating pipe, and the other end of the heating pipe is connected to the outlet through the third outlet pipe.

[0017] By adopting the above technical solution, the wall-mounted water dispenser also has the function of heating drinking water, and there is no conflict with the structure of the refrigeration device.

[0018] In one embodiment, the heating pipeline includes a heating tube and a heater assembly. The heater assembly includes a first heater and a second heater, which are detachably connected. The heating tube is located between the first heater and the second heater to heat the heating tube.

[0019] By adopting the above technical solution, it is convenient to inspect, repair and replace the heating tube and heater assembly.

[0020] In one embodiment, a second water outlet pipe is provided at the other end of the circulating water circuit, and the second water outlet pipe is connected to the drain outlet of the wall-mounted water dispenser so that the circulating water can be discharged from the drain outlet.

[0021] By adopting the above technical solution, it is easy to discharge and collect circulating water, and the circulating water can be reused to save costs.

[0022] In one embodiment, the second water outlet pipe is connected to the third water outlet pipe to form an intersection;

[0023] The intersection divides the second outlet pipe into a first connecting pipe and a drainage pipe. The first connecting pipe is located between the intersection and the circulating water circuit, and the drainage pipe is located between the intersection and the drain outlet. A first stop valve is installed on the first connecting pipe, and a second stop valve is installed on the drainage pipe.

[0024] The intersection divides the third water outlet pipe into a second connecting pipe and a fourth water outlet pipe. The second connecting pipe is located between the intersection and the heating pipe, and the fourth water outlet pipe is located between the intersection and the water outlet. A third stop valve is installed on the second connecting pipe, and a fourth stop valve is installed on the fourth water outlet pipe.

[0025] A descaling agent dispenser is installed on the first connecting pipeline to allow descaling agent to be added into the first connecting pipeline.

[0026] By adopting the above technical solution, scale in the heating pipes can be cleaned, and the water and scale used for cleaning can be drained.

[0027] In one embodiment, the cooling housing includes a first housing and a second housing, which are detachably connected. The second housing is provided with an installation port, and the semiconductor cooling component is installed on the installation port to achieve direct cooling of the cooling pipes and circulating water circuit.

[0028] By adopting the above technical solution, the obstruction between the semiconductor refrigeration component and the pipeline that needs to be refrigerated is avoided, thereby further improving the refrigeration effect of the wall-mounted pipeline water dispenser; at the same time, it facilitates the inspection, maintenance and replacement of the internal structure of the refrigeration device.

[0029] Secondly, the method for cleaning scale inside the heating pipes of the wall-mounted water dispenser provided by the present invention includes the following steps:

[0030] Provide the aforementioned wall-mounted piped water dispenser;

[0031] Water is supplied to the circulating water system through the second inlet pipe;

[0032] Open the first and third stop valves, and close the second and fourth stop valves;

[0033] Descaling agent is added into the first connecting pipe through the descaling agent dispenser, so that the clean water formed by water and descaling agent enters the heating pipe until the amount of clean water in the heating pipe reaches the threshold, and then the first stop valve is closed.

[0034] After the scale dissolves into the cleaning water, open the second stop valve to clean the cleaning water and residue in the heating pipes.

[0035] By adopting the above technical solution, scale in the heating pipes can be cleaned, and the water and scale used for cleaning can be drained.

[0036] In one embodiment, cleaning the heating pipes and removing cleaning water and residue specifically includes:

[0037] The drinking water in the storage tank is added to the third inlet pipe;

[0038] The drinking water is pressurized by a second booster pump;

[0039] Pressurized drinking water is flushed into the heating pipes, carrying away the clean water and residue in the heating pipes through the drain pipes and drain outlets until all the clean water and residue in the heating pipes are discharged.

[0040] By adopting the above technical solution, the effect of cleaning water and residue discharge is improved; at the same time, no additional equipment is needed for discharge, so the size of the wall-mounted pipeline water dispenser does not need to be increased.

[0041] In summary, the present invention has at least one of the following beneficial technical effects:

[0042] 1. When the semiconductor refrigeration component cools the refrigeration pipes, the drinking water flowing into the refrigeration pipes cools down due to the temperature drop of the refrigeration pipes. At the same time, the semiconductor refrigeration component cools the circulating water circuit, causing the temperature of the circulating water flowing inside the circulating water circuit to drop. Since the length of the circulating water circuit is much greater than the length of the refrigeration pipes, the cooling time of the circulating water is longer to reach a lower temperature. Therefore, the circulating water can further cool the refrigeration pipes, increasing the cooling rate of the drinking water, thereby improving the cooling effect of the wall-mounted pipeline water dispenser without increasing the volume.

[0043] 2. The design of the circulating water circuit not only improves the cooling effect of the wall-mounted water dispenser, but also, through the design of the second and third water outlet pipes, can clean the scale in the heating pipes and drain the water and scale used for cleaning.

Detailed Implementation

[0050] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] The wall-mounted piped water dispenser in this embodiment of the invention, see [link / reference]. Figure 1 , 2 As shown, the wall-mounted piped water dispenser includes a water storage tank 3, a refrigeration unit 1, and a heating unit 2. The water storage tank 3 and the refrigeration unit 1 are connected by a pipe, and the water storage tank 3 and the heating unit 2 are connected by another pipe. The water storage tank 3 is provided with an inlet 6 for filtered drinking water to enter the water storage tank 3. The refrigeration unit 1 includes:

[0052] Refrigeration housing;

[0053] The refrigeration pipe 103 is located inside the refrigeration housing. One end of the refrigeration pipe 103 is connected to the water storage tank 3 through the first water inlet pipe, and the other end is connected to the water outlet 7 of the wall-mounted water dispenser through the first water outlet pipe.

[0054] The circulating water path 104 is arranged around the refrigeration pipe 103 along the water flow direction in the refrigeration pipe 103.

[0055] A semiconductor cooling component 106 is disposed on a cooling housing to cool the cooling pipe 103 and the circulating water pipe 104.

[0056] Therefore, this invention cools the cooling pipe 103 by activating the semiconductor cooling component 106. The drinking water in the water storage tank 3 enters the cooling pipe 103 through the first water inlet pipe, thus reducing the temperature of the drinking water inside the cooling pipe 103. At the same time, the semiconductor cooling component 106 cools the circulating water path 104, causing the temperature of the circulating water flowing inside the circulating water path 104 to drop. Since the length of the circulating water path 104 is much greater than the length of the cooling pipe 103, the cooling time of the circulating water is longer, and the temperature of the circulating water is lower than that of the drinking water. Therefore, the circulating water can further cool the cooling pipe 103, increasing the cooling rate of the drinking water, thereby improving the cooling effect of the wall-mounted water dispenser without increasing the volume.

[0057] Preferred, see Figure 2 As shown, the cooling pipe 103 is a U-shaped pipe, and the starting point of the circulating water path 104 is the connection point between the cooling pipe 103 and the first water inlet pipe. One end of the circulating water path 104 is provided with a second water inlet pipe 105, and part of the second water inlet pipe 105 is located inside the cooling housing, so as to realize that the semiconductor cooling component 106 cools the second water inlet pipe 105.

[0058] Specifically, drinking water in the water storage tank 3 enters from one end of the U-shaped pipe through the first inlet pipe and flows out from the other end. A circulating water path 104 is arranged around the U-shaped pipe from the beginning to the end. The initial position of the circulating water path 104 is at the end of the U-shaped pipe. Therefore, part of the second inlet pipe 105 will be located on the side of the U-shaped pipe, that is, inside the cooling housing. The semiconductor cooling component 106 is arranged on the side of the U-shaped pipe. Therefore, the semiconductor cooling component 106 not only cools the cooling pipe 103 and the circulating water path 104, but also cools the second inlet pipe 105, increasing the flow path of the circulating water in the cooling state, thereby increasing the cooling time of the circulating water and further improving the cooling effect of the wall-mounted pipeline water dispenser.

[0059] Further, see Figure 1As shown, a first booster pump 4 is installed between the refrigeration pipe 103 and the first water outlet pipe to enable drinking water to flow out from the water outlet 7.

[0060] Specifically, the cooled drinking water flows in through the inlet of the first booster pump 4, is pressurized, and then flows out through the outlet of the first booster pump 4. Finally, it flows out through the first outlet pipe from the outlet 7, thereby increasing the flow rate of the drinking water through the U-shaped pipe and thus improving the water output efficiency of the wall-mounted water dispenser.

[0061] Preferred, see Figure 1 As shown, a specific structure of a heating device 2 is provided:

[0062] The heating device 2 includes a third water inlet pipe, a second booster pump 5, a heating pipe and a third water outlet pipe. The inlet end of the second booster pump 5 is connected to the water storage tank 3 through the third water inlet pipe. The outlet end of the second booster pump 5 is connected to one end of the heating pipe. The other end of the heating pipe is connected to the water outlet 7 through the third water outlet pipe.

[0063] Specifically, the drinking water in the water storage tank 3 flows in from the inlet end of the second booster pump 5 through the third inlet pipe. After being boosted by the second booster pump 5, it flows into the heating pipe from the outlet end of the second booster pump 5. After being heated by the heating pipe, the drinking water finally flows into the third outlet pipe and flows out from the outlet 7, so as to realize the function of heating drinking water of the wall-mounted pipeline water dispenser.

[0064] Further, see Figure 3 As shown, a specific structure of a heating pipe is provided:

[0065] The heating pipeline includes a heating tube 203 and a heater assembly. The heater assembly includes a first heater 201 and a second heater 202. The first heater 201 and the second heater 202 are detachably connected, and the heating tube 203 is located between the first heater 201 and the second heater 202 to heat the heating tube 203.

[0066] Specifically, the outlet end of the second booster pump 5 is connected to one end of the heating tube 203, and the other end of the heating tube 203 is connected to the water outlet 7 through the third water outlet pipe. The heater is divided into a first heater 201 and a second heater 202 located on both sides of the heating tube 203. The first heater 201 and the second heater 202 clamp the heating tube 203 and heat the heating tube 203, thereby increasing the temperature of the drinking water in the heating tube 203. At the same time, if the heating pipe malfunctions, the connecting parts between the first heater 201 and the second heater 202 can be removed, which facilitates the inspection, maintenance and replacement of the heating tube 203 and the heater assembly.

[0067] Preferred, see Figure 1 ,4 As shown, a second water outlet pipe is provided at the other end of the circulating water circuit 104, and the second water outlet pipe is connected to the drain outlet 8 of the wall-mounted water dispenser so that the circulating water can be discharged from the drain outlet 8.

[0068] Specifically, one end of the circulating water path 104 is connected to the circulating water through the second inlet pipe 105. The circulating water flows along the circulating water path 104 and enhances the cooling effect of the wall-mounted water dispenser. Finally, it flows out through the second outlet pipe at the other end of the circulating water path 104. The other end of the second outlet pipe is connected to the drain outlet 8 so that the circulating water can be discharged from the drain outlet 8. It can also be used for the collection and reuse of circulating water.

[0069] Further, see Figure 1 , 5 As shown, a specific structure is provided to clean the scale that forms on the inner wall of the heating pipe during long-term heating of drinking water:

[0070] The second and third water outlet pipes are connected to form an intersection.

[0071] The intersection divides the second outlet pipe into a first connecting pipe 9 and a drainage pipe 10. The first connecting pipe 9 is located between the intersection and the circulating water circuit 104, and the drainage pipe 10 is located between the intersection and the drain outlet 8. A first stop valve 11 is installed on the first connecting pipe 9, and a second stop valve 12 is installed on the drainage pipe 10.

[0072] The intersection divides the third water outlet pipe into a second connecting pipe 13 and a fourth water outlet pipe 14. The second connecting pipe 13 is located between the intersection and the heating pipe, and the fourth water outlet pipe 14 is located between the intersection and the water outlet 7. A third stop valve 15 is installed on the second connecting pipe 13, and a fourth stop valve 16 is installed on the fourth water outlet pipe 14.

[0073] A descaling agent dispenser 17 is provided on the first connecting pipe 9 to allow descaling agent to be dispensed into the first connecting pipe 9.

[0074] It should be noted that descaling agents are preferably in solid form for easy storage and application, such as in bead or spherical shapes, which gradually release scale-inhibiting chemicals into the water. For example, Kaidefei polyphosphate balls are glass spheres containing food-grade additives. Additionally, KL-102 solid scale cleaner and LX-056A solid descaling agent are also common solid descaling agents; they thoroughly remove scale from equipment through dissolution and are safe for materials such as stainless steel and copper.

[0075] Specifically, the second water outlet pipe is connected to the third water outlet pipe, and the connection point of the two pipes is recorded as the intersection point. Using the intersection point as the dividing point, the second water outlet pipe is divided into the first connecting pipe 9 and the drainage pipe 10, and the third water outlet pipe is divided into the second connecting pipe 13 and the fourth water outlet pipe 14. Each pipe is equipped with a water stop valve. A descaling agent dispenser 17 is installed on the first connecting pipe 9, and the descaling agent dispenser 17 stores descaling agent.

[0076] When descaling of the heating pipeline is required, open the first stop valve 11 and the third stop valve 15, and simultaneously close the second stop valve 12 and the fourth stop valve 16. The water in the circulating water circuit 104 (which can be tap water, drinking water, or circulating water, as long as it is harmless to the human body) flows along the first connecting pipe 9 and the second connecting pipe 13, and comes into contact with the descaling agent put into the first connecting pipe 9 to form clean water, which finally enters the heating pipeline until the amount of clean water in the heating pipeline reaches the threshold, at which point the first stop valve 11 is closed. If the water temperature is too low to completely dissolve the descaling agent in the water, the heating pipeline inside the heater assembly can be heated to increase the temperature of the clean water, thereby achieving a better descaling effect.

[0077] When it is necessary to drain the clean water and residue in the heating pipe, open the second stop valve 12, and the clean water and residue in the heating pipe will be discharged from the drain outlet 8 along the second connecting pipe 13 and the drain pipe 10.

[0078] When it is necessary to heat drinking water, open the third stop valve 15 and the fourth stop valve 16, and close the first stop valve 11 and the second stop valve 12.

[0079] When it is necessary to drain the circulating water, open the first stop valve 11 and the second stop valve 12, and close the third stop valve 15 and the fourth stop valve 16.

[0080] Preferred, see Figure 2 As shown, a specific structure of a refrigeration housing is provided:

[0081] The cooling housing includes a first housing 101 and a second housing 102, which are detachably connected. The second housing 102 is provided with an installation port 107, and the semiconductor cooling component 106 is installed on the installation port 107 to achieve direct cooling of the cooling pipe 103 and the circulating water pipe 104.

[0082] Specifically, the refrigeration housing is made into two parts: a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 can be connected by snap-fit ​​components or bolt assemblies to achieve a detachable connection between the first housing 101 and the second housing 102, which facilitates installation and disassembly. The refrigeration pipe 103 and the circulating water pipe 104 are fixed inside the refrigeration housing. An installation port 107 is opened on the second housing 102 to avoid the semiconductor refrigeration component 106 being blocked by the housing from the pipe that needs to be refrigerated, thereby further improving the refrigeration effect of the wall-mounted water dispenser. At the same time, it facilitates the inspection, maintenance and replacement of the internal structure of the refrigeration device 1.

[0083] The method for cleaning scale inside the heating pipes of a wall-mounted water dispenser according to an embodiment of the present invention includes the following steps:

[0084] We offer wall-mounted piped water dispensers;

[0085] Water is supplied to the circulating water circuit 104 through the second inlet pipe 105;

[0086] Open the first stop valve 11 and the third stop valve 15, and close the second stop valve 12 and the fourth stop valve 16;

[0087] Descaling agent is added into the first connecting pipe 9 through the descaling agent injector 17, so that the clean water formed by water and descaling agent enters the heating pipe until the amount of clean water in the heating pipe reaches the threshold, and then the first stop valve 11 is closed.

[0088] After the scale dissolves into the cleaning water, open the second stop valve 12 to clean the cleaning water and residue in the heating pipe.

[0089] By adopting the above technical solution, scale in the heating pipes can be cleaned, and the water and scale used for cleaning can be drained.

[0090] Specifically, the second water outlet pipe is connected to the third water outlet pipe, and the connection point of the two pipes is recorded as the intersection point. Using the intersection point as the dividing point, the second water outlet pipe is divided into the first connecting pipe 9 and the drainage pipe 10, and the third water outlet pipe is divided into the second connecting pipe 13 and the fourth water outlet pipe 14. Each pipe is equipped with a water stop valve. A descaling agent dispenser 17 is installed on the first connecting pipe 9, and the descaling agent dispenser 17 stores descaling agent.

[0091] When descaling of the heating pipeline is required, open the first stop valve 11 and the third stop valve 15, and simultaneously close the second stop valve 12 and the fourth stop valve 16. The water in the circulating water circuit 104 (which can be tap water, drinking water, or circulating water, as long as it is harmless to the human body) flows along the first connecting pipe 9 and the second connecting pipe 13, and comes into contact with the descaling agent put into the first connecting pipe 9 to form clean water, which finally enters the heating pipeline until the amount of clean water in the heating pipeline reaches the threshold, at which point the first stop valve 11 is closed. If the water temperature is too low to completely dissolve the descaling agent in the water, the heating pipeline inside the heater assembly can be heated to increase the temperature of the clean water, thereby achieving a better descaling effect.

[0092] When it is necessary to drain the clean water and residue in the heating pipe, open the second stop valve 12, and the clean water and residue in the heating pipe will be discharged from the drain outlet 8 along the second connecting pipe 13 and the drain pipe 10.

[0093] When it is necessary to heat drinking water, open the third stop valve 15 and the fourth stop valve 16, and close the first stop valve 11 and the second stop valve 12.

[0094] When it is necessary to drain the circulating water, open the first stop valve 11 and the second stop valve 12, and close the third stop valve 15 and the fourth stop valve 16.

[0095] Furthermore, clean the heating pipes, removing cleaning water and residue, specifically including:

[0096] The drinking water in water storage tank 3 is added to the third water inlet pipe;

[0097] The drinking water is pressurized by the second booster pump 5;

[0098] Pressurized drinking water is flushed into the heating pipe, carrying away the clean water and residue in the heating pipe through the drain pipe 10 and drain outlet 8 until all the clean water and residue in the heating pipe are discharged.

[0099] It should be noted that, in order to ensure the complete discharge of clean water and residue, the quality of drinking water discharged from the drain outlet 8 along the second connecting pipe 13 and the drain pipe 10 can be tested.

[0100] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
