Description

Technical Field

[0001] The invention relates to the technical field of direct drinking machines, and in particular to a direct drinking machine with a water tank high-temperature drainage and scald-proof pipeline structure. Background Art

[0002] A water purifier, also called a water purifier or water purifier, is a water treatment equipment that deeply filters and purifies water according to the requirements for water use.

[0003] On the one hand, if the water tank is not used for a long time and is heated to 100°C, the water vapor will escape and the weight of the water will gradually increase. Especially for companies that are closed on Saturdays and Sundays, after two days of sedimentation, there will be more impurities in the water resources deposited in the water, that is, heavy water that is harmful to the human body will be produced in the water tank.

[0004] On the other hand, there are generally drain ports and exhaust ports at the back of existing water tanks. The drain port is used to drain water from the water tank during maintenance. If the temperature of the water discharged from the drain port is 90°C, the drain port pipe is generally made of PVC material, which can easily scald the drain port pipe.

[0005] To this end, we provide a direct drinking machine with a water tank high-temperature drainage and anti-scalding pipeline structure to solve the above problems. Summary of the invention

[0008] The hot water discharge part includes a heating system, a timed emptying system and a drainage system. The timed emptying system includes an emptying part and a cooling regulating valve arranged on the drainage path of the emptying part. The cooling regulating valve has a mixed flow space, a through hole A, a through hole B and a through hole C. The through hole A is connected to the water outlet path of the heating system, the through hole B is connected to an external cold water pipe, and the through hole C is connected to the drainage part. The mixed flow space receives and mixes the hot water discharged from the heating system and the cold water from the external cold water pipe and discharges the mixed warm water to the drainage part.

[0009] The above-mentioned direct drinking machine has the advantages of simple structure and reliable and stable operation, and can realize the anti-scalding function of the pipes connected to the high-temperature drainage structure without changing the original high-temperature drainage structure.

[0010] As a further optimization of the above solution, the above emptying part includes a manual emptying valve and a timed emptying valve, so that the above emptying part has two emptying modes of manual emptying and timed emptying, and the emptying options are more diverse.

[0011] As a further optimization of the above scheme, the drainage system also includes a first water outlet, a second water outlet and a circulation solenoid valve. The first water outlet is connected to the heating system with a first water outlet solenoid valve, the second water outlet is connected to the heating system with a second water outlet solenoid valve, the circulation solenoid valve is electrically connected to the first water outlet solenoid valve and the second water outlet solenoid valve respectively and starts the first water outlet solenoid valve and the second water outlet solenoid valve at a fixed time. By setting the circulation solenoid valve, the water stored in the water tank can be regularly cleaned to avoid the generation of heavy water harmful to the human body in the water tank.

[0012] As a further optimization of the above scheme, the heating system includes a heating tank and a heating wire arranged inside the heating tank. A water level probe is arranged inside the heating tank to detect the water level inside the heating tank online through the water level probe.

[0013] As a further optimization of the above scheme, the above-mentioned filtering part includes a first PP cotton filter element, a front carbon, a second PP cotton filter element and an RO membrane which are arranged in sequence along the inflow path of the water inlet part. A booster pump is provided between the second PP cotton filter element and the RO membrane. The setting of the booster pump is to achieve the purpose of pressurization so that the water resources after primary filtration can better pass through the RO membrane. The above-mentioned filtering part also includes coconut shell activated carbon and a rear PP cotton filter element placed behind the RO membrane. The coconut shell activated carbon can greatly enhance the taste of the water resources to ensure that more drinking pure water is produced by the direct drinking machine of the present invention.

[0014] As a further optimization of the above scheme, the through hole A and the through hole B are arranged symmetrically up and down, the mixed flow space is arranged between the through hole A and the through hole B, the water inlet end of the mixed flow space is provided with a connecting cylinder with a water guide hole respectively connected with the through hole A and the through hole B, and the water outlet end of the mixed flow space is arranged vertically, so as to extend the actual mixed flow area of ​​the mixed flow space, so that the water flow is mixed in a bending channel similar to an "S" shape, extending the mixing time, and ensuring that the warm water after mixing will not scald the pipeline.

[0015] As a further optimization of the above-mentioned scheme, the above-mentioned mixed flow space includes a detachable front body and a rear body, and the connecting component connecting the front body and the rear body is a locking nut, which is arranged on the rear body and engages with the annular engaging groove formed on the outer circumferential surface of the front body. A first step is formed inside the above-mentioned front body to support and fix one end of the connecting tube, and a second step is formed inside the above-mentioned rear body to support and fix the other end of the connecting tube, so that the above-mentioned mixed flow space constitutes a detachable structure, thereby facilitating the staff to regularly replace the connecting tube and avoiding the connection tube from being blocked due to problems such as scale generation.

[0018] During the emptying operation, hot water is introduced from the water tank into the mixed flow space of the cooling regulating valve, and cold water is introduced from the external cold water pipe into the mixed flow space of the cooling regulating valve. The hot water and cold water are mixed to become warm water and discharged from the through hole C in the mixed flow space. Since the temperature of the warm water after mixing is greatly reduced, scalding of the pipeline is avoided.

[0039] The heating system 31 includes a heating tank 311 and a heating wire 312 arranged inside the heating tank 311. A water level probe 313 is arranged inside the heating tank 311. In this embodiment, there are four water level probes to better confirm the water level in the heating tank. At the same time, a temperature probe is also placed inside the heating tank to achieve the purpose of online detection of the temperature inside the heating tank.

[0040] The timed emptying system 32 includes an emptying part 321 and a cooling regulating valve 5 arranged on the drainage path of the emptying part 321. The cooling regulating valve 5 has a mixing space 51, a through hole A52, a through hole B53 and a through hole C54. The through hole A52 is connected to the water outlet path of the heating system 31, the through hole B53 is connected to the external cold water pipe, and the through hole C54 is connected to the drainage part. The mixing space 51 receives and mixes the hot water discharged from the heating system 31 and the cold water from the external cold water pipe and discharges the mixed warm water to the drainage part. The emptying part 321 includes a manual emptying valve 3211 and a timed emptying valve 3212, which are specifically shown in the attached Figure 2 The above-mentioned timed drain valve 3212 is a drain solenoid valve, while the name of the manual drain valve 3211 remains unchanged.

[0041] Preferably, for the external cold water pipe, since the tap water in the water pipe is cold water, the external cold water pipe in this embodiment is a tap water pipe, so there is no need to connect special cold water equipment externally, thereby reducing the use cost.

[0042] The drainage system 33 includes a first water outlet 331, a second water outlet 332 and a circulation solenoid valve 333. The first water outlet 331 is connected to the heating system 31 via a first water outlet solenoid valve 3311. The second water outlet 332 is connected to the heating system 31 via a second water outlet solenoid valve 3321. The circulation solenoid valve 333 is electrically connected to the first water outlet solenoid valve 3311 and the second water outlet solenoid valve 3321 respectively and starts the first water outlet solenoid valve 3311 and the second water outlet solenoid valve 3321 at a fixed time.

[0043] Specifically, the through hole A52 and the through hole B53 are arranged symmetrically up and down, the mixed flow space 51 is arranged between the through hole A52 and the through hole B53, the water inlet end of the mixed flow space 51 is provided with a connecting tube 6 with a water guide hole respectively connected with the through hole A52 and the through hole B53, and the water outlet end of the mixed flow space 51 is arranged vertically, the mixed flow space 51 includes a detachable front body 511 and a rear body 512, the connecting part connecting the front body 511 and the rear body 512 is a locking nut 513, the locking nut 513 is arranged on the rear body 512 and is engaged with an annular engaging groove 5111 formed on the outer circumferential surface of the front body, the interior of the front body 511 is formed with a first step 5112 that supports and fixes one end of the connecting tube 6, and the interior of the rear body 512 is formed with a second step 5121 that supports and fixes the other end of the connecting tube 6. By adopting a mixing space 51 with an S-shaped cross-section, the actual mixing area of ​​the mixing space 51 is extended, so that the water flow is mixed in a bending channel similar to the "S" shape, the mixing time is extended, and it is ensured that the warm water after mixing will not scald the pipeline. At the same time, the above-mentioned mixing space 51 constitutes a detachable structure, so that the staff can replace the connecting tube 6 regularly to avoid the connection tube 6 being blocked due to the generation of scale and other problems.

[0044] In actual use, the hot water discharged from the water tank and the hot water introduced from the external cold water pipe both enter the mixed flow space through the vertically symmetrical through holes A and through holes B. Since the mixed flow space has a long lateral mixed flow area, the hot water and cold water in the mixed flow space have sufficient mixing time, so that the temperature of the warm water discharged from the through hole C is greatly lower than the temperature of the hot water discharged from the water tank, thereby greatly reducing the occurrence of scalding of the pipeline.

[0045] Further preferably, without considering the cost, a micro-drive motor can be installed on the rear body 512 of the mixed flow space 51, and the rotating shaft of the micro-drive motor passes through the inner cavity of the rear body 512, and is connected to the connecting tube 6 through a rotating sleeve, so as to achieve the purpose of the micro-drive motor driving the connecting tube 6. Furthermore, in actual use, through the rotation of the connecting tube 6, the hot water and cold water in the mixed flow space can be mixed more evenly.

[0046] Furthermore, for the through hole A, through hole B and through hole C, in this embodiment, the connection with the pipeline can adopt a threaded structure to facilitate disassembly and use.

[0047] Furthermore, the rear body 512 of the mixed flow space 51 can be supported by a transparent material. When the rear body 512 of the mixed flow space 51 is made of a transparent material, the user can easily understand the use status of the connecting tube 6 through the transparent rear body 512. For example, if the installation status of the connecting tube 6 is poor or the connecting tube 6 is blocked, in this case, the user can not only take appropriate measures immediately, but also the user can easily and accurately grasp the replacement time of the connecting tube 6 through the naked eye, so that the use and maintenance of the connecting tube 6 can always remain efficient and clean.

[0048] The cold water discharge part 4 includes a third water outlet solenoid valve and a fourth water outlet solenoid valve directly connected to the filtering part. The cold water discharge part discharges cold water.

[0049] Also includes:

[0050] The button part is arranged on the front side of the box body, and the button panel is electrically connected to the cold water discharge part and the hot water discharge part through the control panel. Specifically, the button panel is provided with control buttons respectively connected to the first water outlet solenoid valve, the second water outlet solenoid valve, the third water outlet solenoid valve and the fourth water outlet solenoid valve.

[0051] The specific implementation steps of the emptying operation of the present invention are as follows:

[0052] During the emptying operation, hot water is introduced from the water tank into the mixed flow space 51 of the cooling regulating valve 5, and cold water is introduced from the external cold water pipe into the mixed flow space 51 of the cooling regulating valve 5. The hot water and the cold water are mixed to become warm water and are discharged from the through hole C54 of the mixed flow space 51. Since the temperature of the warm water after mixing is greatly reduced, the phenomenon of scalding the pipeline is avoided.

[0053] To sum up, the direct drinking machine with a water tank high-temperature drainage and anti-scalding pipeline structure of the present invention has the advantages of simple structure and reliable and stable operation, and can realize the anti-scalding function of the pipeline connected to the high-temperature drainage structure without changing the original high-temperature drainage structure.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
