Description

Technical Field

[0001] The invention relates to the technical field of pipeline machines, and in particular to a wall-mounted pipeline drinking water machine. Background Art

[0002] Pipeline water dispenser is also called pipeline water dispenser. It is divided into wall-mounted and vertical types, and is generally used in homes, offices, etc. Traditional pipeline water dispensers only have a single function of heating or cooling, and cannot meet the user's needs for both cold and hot water. With the improvement of living standards and technological progress, people's requirements for drinking water quality are getting higher and higher, and multifunctional integrated products are becoming more and more popular among consumers.

[0003] There are some multifunctional integrated pipeline water dispensers in the prior art, such as the utility model patent with publication number: CN220442482U discloses an embedded pipeline machine with a rapid cooling and heating system, including a main body, the main body is provided with a filtering mechanism, a rapid heating device and a rapid cooling device, the rapid cooling device includes a heating end and a cooling end, the clean water outlet end of the filtering mechanism is connected to a water storage tank, the first water outlet end of the water storage tank is connected to the rapid heating device, the second water outlet end of the water storage tank is connected to the cooling end of the rapid cooling device, the waste water outlet end of the filtering mechanism is connected to the heating end of the rapid cooling device, and the cooling end is connected to the downstream of the rapid heating device. The water outlet structure; a TDS detection module is connected between the filtering mechanism and the water storage tank. The utility model has the following advantages and effects: the scheme uses a new mechanical structure, has the effects of both cold water and hot water preparation, good cooling effect, low noise, and waste water utilization.

[0004] However, in order to meet the requirements of small size and multiple functions, the existing wall-mounted pipeline water dispensers are mainly cooled by semiconductor refrigeration (the semiconductor refrigeration water dispenser is equipped with a refrigeration plate made of special semiconductor materials. When current passes through these semiconductor particles, heat is transferred from one side of the particles to the other side, thereby achieving a cooling effect). This refrigeration method is inferior to compressor refrigeration, but compressor refrigeration requires equipment such as a compressor, condenser, expansion valve and evaporator, which will greatly increase the size of the wall-mounted pipeline water dispenser, making it unsuitable for scenarios with smaller spaces. Summary of the invention

[0005] In view of the defects existing in the prior art, the technical problem solved by the present invention is: how to improve the refrigeration effect of the wall-mounted pipeline drinking fountain without increasing the volume.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a wall-mounted pipeline water dispenser, comprising a water storage tank, a refrigeration device and a heating device, wherein the refrigeration device comprises: Refrigeration housing; A refrigeration pipeline is arranged inside the refrigeration shell, one end of the refrigeration pipeline is connected to the water storage tank through a first water inlet pipeline, and the other end of the refrigeration pipeline is connected to the water outlet of the wall-mounted pipeline drinking fountain through a first water outlet pipeline; A circulating water circuit is disposed on the refrigeration pipeline along the water flow direction in the refrigeration pipeline; The semiconductor refrigeration component is arranged on the refrigeration shell to realize refrigeration of the refrigeration pipeline and the circulating water circuit.

[0007] By adopting the above technical scheme, when the semiconductor refrigeration component cools the refrigeration pipeline, the drinking water entering the refrigeration pipeline is cooled due to the temperature of the refrigeration pipeline. At the same time, the semiconductor refrigeration component cools the circulating water circuit, resulting in the temperature of the circulating water flowing inside the circulating water circuit to drop. Since the length of the circulating water circuit is much larger than the length of the refrigeration pipeline, the cooling time of the circulating water is longer to reach a lower temperature. Therefore, the circulating water can further cool the refrigeration pipeline and increase the cooling rate of the drinking water, thereby improving the cooling effect of the wall-mounted pipeline water dispenser while ensuring that the volume does not increase.

[0008] In combination with the first aspect, in one embodiment, the refrigeration pipeline is a U-shaped pipeline, the starting point of the circulating water circuit is the connection point between the refrigeration pipeline and the first water inlet pipeline, a second water inlet pipeline is provided at one end of the circulating water circuit, and part of the second water inlet pipeline is located inside the refrigeration shell, so as to enable the semiconductor refrigeration component to cool the second water inlet pipeline.

The inlet end of the second booster pump is connected to the water tank through the third water inlet pipeline, the outlet end of the second booster pump is connected to one end of the heating pipeline, and the other end of the heating pipeline is connected to the water outlet through the third water outlet pipeline.

[0015] By adopting the above technical solution, it is convenient to inspect, repair and replace the heating tube and the heater assembly.

[0016] In one embodiment, a second water outlet pipeline is provided at the other end of the circulating water circuit, and the second water outlet pipeline is connected to the drain outlet of the wall-mounted pipeline drinking fountain to discharge the circulating water from the drain outlet.

[0017] By adopting the above technical solution, the discharge and collection of circulating water are facilitated, and the circulating water can be reused to save costs.

[0018] In one embodiment, the second water outlet pipeline is connected to the third water outlet pipeline to form an intersection; The intersection divides the second water outlet pipeline into a first connecting pipeline and a drainage pipeline, the first connecting pipeline is located between the intersection and the circulating water circuit, the drainage pipeline is located between the intersection and the drainage port, a first water stop valve is provided on the first connecting pipeline, and a second water stop valve is provided on the drainage pipeline; The intersection divides the third water outlet pipeline into a second connecting pipeline and a fourth water outlet pipeline, the second connecting pipeline is located between the intersection and the heating pipeline, the fourth water outlet pipeline is located between the intersection and the water outlet, a third water stop valve is provided on the second connecting pipeline, and a fourth water stop valve is provided on the fourth water outlet pipeline; The first connecting pipeline is provided with a descaling agent injector to inject the descaling agent into the first connecting pipeline.

[0019] By adopting the above technical solution, the scale in the heating pipeline can be cleaned, and at the same time, the water and scale used for cleaning can also be discharged.

[0020] In one embodiment, the refrigeration shell includes a first shell and a second shell, the first shell and the second shell are detachably connected, and a mounting port is provided on the second shell, and the semiconductor refrigeration component is installed on the mounting port to realize direct cooling of the refrigeration pipeline and the circulating water circuit.

Since the length of the circulating water circuit is much longer than the length of the refrigeration pipeline, the cooling time of the circulating water is longer to reach a lower temperature. Therefore, the circulating water can further cool the refrigeration pipeline and increase the cooling rate of the drinking water, thereby improving the cooling effect of the wall-mounted pipeline drinking machine without increasing the volume; 2. The design of the circulating water circuit can not only improve the cooling effect of the wall-mounted pipeline water dispenser, but also through the design of the second water outlet pipeline and the third water outlet pipeline, it can clean the scale in the heating pipeline and discharge the water and scale used for cleaning.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0030] The wall-mounted pipeline drinking fountain in the embodiment of the present invention is shown in FIG. Figure 1 , 2 As shown, the wall-mounted pipeline drinking fountain comprises a water tank 3, a refrigeration device 1 and a heating device 2. The water tank 3 and the refrigeration device 1 are connected by a pipeline, and the water tank 3 and the heating device 2 are connected by another pipeline. The water tank 3 is provided with a water inlet 6 for filtered drinking water to enter the water tank 3. The refrigeration device 1 comprises: Refrigeration housing; A refrigeration pipeline 103 is arranged inside the refrigeration shell, one end of the refrigeration pipeline 103 is connected to the water storage tank 3 through a first water inlet pipeline, and the other end of the refrigeration pipeline 103 is connected to the water outlet 7 of the wall-mounted pipeline drinking machine through a first water outlet pipeline; A circulating water circuit 104 is disposed on the refrigeration pipeline 103 along the water flow direction in the refrigeration pipeline 103; The semiconductor refrigeration component 106 is disposed on the refrigeration shell to realize refrigeration of the refrigeration pipeline 103 and the circulating water circuit 104 .

[0031] It can be seen that the present invention cools the refrigeration pipeline 103 by turning on the semiconductor refrigeration component 106, and the drinking water in the water storage tank 3 is passed into the refrigeration pipeline 103 through the first water inlet pipeline, so the refrigeration pipeline 103 can reduce the temperature of the drinking water therein; at the same time, the semiconductor refrigeration component 106 cools the circulating water circuit 104, resulting in a decrease in the temperature of the circulating water flowing in the circulating water circuit 104. Since the length of the circulating water circuit 104 is much longer than the length of the refrigeration pipeline 103, the cooling time of the circulating water is longer, and the temperature of the circulating water is lower than the temperature of the drinking water. Therefore, the circulating water can further cool the refrigeration pipeline 103, thereby increasing the cooling rate of the drinking water, thereby improving the refrigeration effect of the wall-mounted pipeline drinking machine without increasing the volume.

[0032] Preferably, see Figure 2 As shown, the refrigeration pipeline 103 is a U-shaped pipeline, the starting point of the circulating water circuit 104 is the connection point between the refrigeration pipeline 103 and the first water inlet pipeline, and a second water inlet pipeline 105 is arranged at one end of the circulating water circuit 104, and part of the second water inlet pipeline 105 is located inside the refrigeration shell, so that the semiconductor refrigeration component 106 can cool the second water inlet pipeline 105.

[0033] Specifically, the drinking water in the water tank 3 is introduced into one end of the U-shaped pipe through the first water inlet pipe and then flows out from the other end. A circulating water circuit 104 is arranged around the starting part to the ending part of the U-shaped pipe. The initial surrounding position of the circulating water circuit 104 is the end of the U-shaped pipe. Therefore, part of the second water inlet pipe 105 will be located on the side of the U-shaped pipe, that is, inside the refrigeration shell, and the semiconductor refrigeration component 106 is arranged on the side of the U-shaped pipe. Therefore, the semiconductor refrigeration component 106 not only cools the refrigeration pipe 103 and the circulating water circuit 104, but also cools the second water inlet pipe 105, which increases the flow path of the circulating water in the refrigerated state, thereby increasing the cooling time of the circulating water, thereby further improving the refrigeration effect of the wall-mounted pipeline water dispenser.

[0034] For further information, see Figure 1 As shown, a first booster pump 4 is provided between the refrigeration pipeline 103 and the first water outlet pipeline to enable drinking water to flow out from the water outlet 7 .

[0035] Specifically, the drinking water after refrigeration flows in through the inlet end of the first booster pump 4, flows out from the outlet end of the first booster pump 4 after being pressurized, and finally flows out from the water outlet 7 through the first water outlet pipe, thereby increasing the flow rate of the drinking water passing through the U-shaped pipe, thereby improving the water outlet efficiency of the wall-mounted pipeline drinking machine.

[0036] Preferably, see Figure 1 As shown, a specific structure of a heating device 2 is provided: The heating device 2 includes a third water inlet pipeline, a second booster pump 5, a heating pipeline and a third water outlet pipeline. The inlet end of the second booster pump 5 is connected to the water tank 3 through the third water inlet pipeline, the outlet end of the second booster pump 5 is connected to one end of the heating pipeline, and the other end of the heating pipeline is connected to the water outlet 7 through the third water outlet pipeline.

[0037] Specifically, the drinking water in the water tank 3 flows into the inlet end of the second booster pump 5 through the third water inlet pipe, is pressurized by the second booster pump 5, and then flows into the heating pipe from the outlet end of the second booster pump 5. After the drinking water is heated by the heating pipe, it finally flows into the third water outlet pipe and flows out from the water outlet 7, so as to realize the function of heating drinking water of the wall-mounted pipeline drinking machine.

[0038] For further information, see Figure 3 As shown, a specific structure of a heating pipeline is provided: The heating circuit 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 achieve heating of the heating tube 203.

[0039] Specifically, the outlet end of the second boost pump 5 is connected to one end of the heating pipe 203, and the other end of the heating pipe 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 pipe 203. The first heater 201 and the second heater 202 clamp the heating pipe 203 and heat the heating pipe 203, thereby increasing the temperature of the drinking water in the heating pipe 203; at the same time, if the heating pipeline fails, the connector between the first heater 201 and the second heater 202 can be removed, thereby facilitating the inspection, maintenance and replacement of the heating pipe 203 and the heater assembly.

[0040] Preferably, see Figure 1 , 4 As shown, a second water outlet pipeline is provided at the other end of the circulating water circuit 104 , and the second water outlet pipeline is connected to the drain outlet 8 of the wall-mounted pipeline drinking machine to discharge the circulating water from the drain outlet 8 .

[0041] Specifically, circulating water is introduced into one end of the circulating water circuit 104 through the second water inlet pipe 105. The circulating water flows along the circulating water circuit 104 and plays a role in improving the cooling effect of the wall-mounted pipeline drinking machine. Finally, it flows out through the second water outlet pipe at the other end of the circulating water circuit 104. The other end of the second water outlet pipe is connected to the drain port 8 to facilitate the discharge of the circulating water from the drain port 8. The circulating water can also be collected and reused.

[0042] For further information, see Figure 1 , 5 As shown, a specific structure is provided to clean the scale generated on the inner wall of the heating pipeline during the long-term heating of drinking water: The second water outlet pipeline is connected to the third water outlet pipeline to form an intersection; The intersection divides the second water outlet pipeline into a first connecting pipeline 9 and a drainage pipeline 10. The first connecting pipeline 9 is located between the intersection and the circulating water circuit 104, and the drainage pipeline 10 is located between the intersection and the drain port 8. The first connecting pipeline 9 is provided with a first water stop valve 11, and the drainage pipeline 10 is provided with a second water stop valve 12. The intersection divides the third water outlet pipeline into a second connecting pipeline 13 and a fourth water outlet pipeline 14. The second connecting pipeline 13 is located between the intersection and the heating pipeline, and the fourth water outlet pipeline 14 is located between the intersection and the water outlet 7. The second connecting pipeline 13 is provided with a third water stop valve 15, and the fourth water outlet pipeline 14 is provided with a fourth water stop valve 16. The first connecting pipeline 9 is provided with a descaling agent injector 17 to inject the descaling agent into the first connecting pipeline 9 .

[0043] It should be noted that the descaling agent is preferably in solid form, which is easy to store and put into, such as beads or balls, and can gradually release scale-inhibiting chemicals into the water. For example, Kaidefei polyphosphate balls are in the form of glass balls and contain food-grade additives. In addition, KL-102 solid scale remover and LX-056A solid descaling agent are also common solid descaling agents. They completely remove scale from the equipment through dissolution and are safe for materials such as stainless steel and copper.

[0044] Specifically, the second water outlet pipeline is connected to the third water outlet pipeline, and the connection point of the two pipelines is recorded as the intersection. The intersection is used as a dividing point to divide the second water outlet pipeline into a first connecting pipeline 9 and a drainage pipeline 10, and the third water outlet pipeline is divided into a second connecting pipeline 13 and a fourth water outlet pipeline 14, and each pipeline is provided with a water stop valve, and a descaling agent injector 17 is provided on the first connecting pipeline 9, and the descaling agent injector 17 stores the descaling agent; When it is necessary to descale the heating pipeline, the first water stop valve 11 and the third water stop valve 15 are opened, and the second water stop valve 12 and the fourth water stop valve 16 are closed at the same time. 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 pipeline 9 and the second connecting pipeline 13, and contacts with the descaling agent put into the first connecting pipeline 9 to form clean water, and finally enters the heating pipeline until the amount of clean water in the heating pipeline reaches a threshold value, and the first water stop valve 11 is closed; if the water temperature is too low and the descaling agent cannot be completely dissolved in the water, the heating pipeline inside it can be heated by the heater assembly to increase the temperature of the clean water, thereby achieving a better descaling effect; When it is necessary to discharge the clean water and residue in the heating pipeline, the second water stop valve 12 is opened, and the clean water and residue in the heating pipeline are discharged from the drain port 8 along the second connecting pipeline 13 and the drain pipeline 10; When it is necessary to heat drinking water, the third water stop valve 15 and the fourth water stop valve 16 are opened, and the first water stop valve 11 and the second water stop valve 12 are closed; When the circulating water needs to be discharged, the first water stop valve 11 and the second water stop valve 12 are opened, and the third water stop valve 15 and the fourth water stop valve 16 are closed.

[0045] Preferably, see Figure 2 As shown, a specific structure of a refrigeration shell is provided: The refrigeration shell includes a first shell 101 and a second shell 102 , which are detachably connected. The second shell 102 is provided with an installation port 107 , and the semiconductor refrigeration component 106 is installed on the installation port 107 to achieve direct cooling of the refrigeration pipeline 103 and the circulating water circuit 104 .

[0046] Specifically, the refrigeration shell is made into two parts, a first shell 101 and a second shell 102, and the first shell 101 and the second shell 102 can be connected by a clamp or a bolt assembly to achieve a detachable connection between the first shell 101 and the second shell 102, which is convenient for installation and disassembly, and the refrigeration pipeline 103 and the circulating water circuit 104 are fixed inside the refrigeration shell; and an installation port 107 is opened on the second shell 102 to avoid shell obstruction between the semiconductor refrigeration component 106 and the pipeline to be refrigerated, thereby further improving the refrigeration effect of the wall-mounted pipeline water dispenser; at the same time, it is convenient for the inspection, maintenance and replacement of the internal structure of the refrigeration device 1.

[0047] The method for cleaning scale in the heating pipeline of the wall-mounted pipeline drinking water machine in the embodiment of the present invention comprises the following steps: Provide wall-mounted pipeline water dispensers; Water is introduced into the circulating water circuit 104 through the second water inlet pipe 105; Open the first water stop valve 11 and the third water stop valve 15, and close the second water stop valve 12 and the fourth water stop valve 16; A descaling agent is added into the first connecting pipeline 9 through the descaling agent injector 17, so that clean water formed by water and the descaling agent enters the heating pipeline, until the amount of clean water in the heating pipeline reaches a threshold, and the first water stop valve 11 is closed; After the scale is dissolved in the clean water, the second water stop valve 12 is opened to clean the clean water and residues in the heating pipeline.

[0048] By adopting the above technical solution, the scale in the heating pipeline can be cleaned, and at the same time, the water and scale used for cleaning can also be discharged.

[0049] Specifically, the second water outlet pipeline is connected to the third water outlet pipeline, and the connection point of the two pipelines is recorded as the intersection. The intersection is used as a dividing point to divide the second water outlet pipeline into a first connecting pipeline 9 and a drainage pipeline 10, and the third water outlet pipeline is divided into a second connecting pipeline 13 and a fourth water outlet pipeline 14, and each pipeline is provided with a water stop valve, and a descaling agent injector 17 is provided on the first connecting pipeline 9, and the descaling agent injector 17 stores the descaling agent; When it is necessary to descale the heating pipeline, the first water stop valve 11 and the third water stop valve 15 are opened, and the second water stop valve 12 and the fourth water stop valve 16 are closed at the same time. 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 pipeline 9 and the second connecting pipeline 13, and contacts with the descaling agent put into the first connecting pipeline 9 to form clean water, and finally enters the heating pipeline until the amount of clean water in the heating pipeline reaches a threshold value, and the first water stop valve 11 is closed; if the water temperature is too low and the descaling agent cannot be completely dissolved in the water, the heating pipeline inside it can be heated by the heater assembly to increase the temperature of the clean water, thereby achieving a better descaling effect; When it is necessary to discharge the clean water and residue in the heating pipeline, the second water stop valve 12 is opened, and the clean water and residue in the heating pipeline are discharged from the drain port 8 along the second connecting pipeline 13 and the drain pipeline 10; When it is necessary to heat drinking water, the third water stop valve 15 and the fourth water stop valve 16 are opened, and the first water stop valve 11 and the second water stop valve 12 are closed; When the circulating water needs to be discharged, the first water stop valve 11 and the second water stop valve 12 are opened, and the third water stop valve 15 and the fourth water stop valve 16 are closed.

[0050] Furthermore, the clean water and residues in the heating pipeline are cleaned, including: The drinking water in the water storage tank 3 is added to the third water inlet pipeline; The drinking water is pressurized by the second booster pump 5; The pressurized drinking water is flushed into the heating pipeline, and is discharged through the drainage pipeline 10 and the drainage port 8 with the clean water and residue in the heating pipeline, until the clean water and residue in the heating pipeline are completely discharged.

[0051] It should be noted that, in order to ensure the complete discharge of clean water and residues, the quality of the drinking water discharged from the drain outlet 8 along the second connecting pipe 13 and the drain pipe 10 may be detected.
