Description

Technical Field

[0001] This application relates to the field of drinking water equipment, and in particular to a dual-tank direct drinking water machine. Background Technology

[0002] As living standards improve, more and more people are focusing on enhancing their quality of life. Water purifiers, as an important appliance for improving quality of life, use filter cartridges to remove harmful substances (such as heavy metals, residual chlorine, bacteria, and viruses) from municipal tap water, making the water safe for direct consumption. At the same time, water purifiers also have a heating function, using a heating chamber inside the machine to heat the water through heating elements, allowing people to have hot or cold water readily available to meet their drinking needs.

[0003] However, as the water purifier is used for a longer period, scale will form in the heating chamber, and the heating element, due to its higher temperature, is more prone to scale buildup. If the scale on the heating element is not cleaned in time, it will reduce heating efficiency, increase energy consumption, and affect the lifespan of the heating element.

[0004] Currently, the common way to clean the scale on the heating element of a water purifier is to disassemble the entire heating tank and clean the scale inside. Although this method can directly contact and remove the scale, it is complicated and time-consuming, increasing the user's maintenance costs. Alternatively, descaling agents can be used, which is more convenient, but the residual descaling agent in the water tank requires a lot of water to rinse completely, resulting in a waste of water resources. Summary of the Invention

[0005] In order to reduce the scale buildup on the heating element of the water purifier and improve its service life, this application provides a dual-tank water purifier.

[0006] This application provides a dual-tank direct drinking water machine, which adopts the following technical solution:

[0007] A dual-tank direct drinking water machine includes a water outlet tank and a filter element. The water outlet tank includes a tank body and a support base slidably connected to the tank body. A heating element is connected to the support base, and the heating element moves into or out of the tank body through the support base.

[0008] The filter element is used to filter municipal tap water; the filter element is connected to the water outlet tank.

[0009] By adopting the above technical solution, the heating element is slidably connected to the housing by the support base, so that the scale can be cleaned by removing the heating element from the housing, which reduces the workload of the overall disassembly and assembly method and reduces the waste of water resources.

[0010] Optionally, a membrane roller is rotatably connected to the outside of the housing, and a collection membrane is provided on the membrane roller. The collection membrane is used to collect the scale cleaned from the heating element. A clamping member is provided on the support base. The clamping member is connected to one end of the collection membrane. The clamping member is used to unfold the collection membrane so that the collection membrane can collect the scale cleaned from the heating element.

[0011] By adopting the above technical solution, after the clamping member holds one end of the collection film, the collection film unfolds as the support base moves, thus facilitating the collection of scale that falls off during the cleaning of the heating element. The collection film provides a convenient method for collecting scale, reducing the amount of cleaning work after scale falls off and improving cleaning efficiency.

[0012] Optionally, the support base is provided with a storage hole, through which the storage film passes and connects to the clamping member.

[0013] By adopting the above technical solution, after the scale removal is completed, when the support moves the heating element into the box, the collecting membrane can pass through the collecting hole and carry the scale out for easy cleaning, thus improving the cleaning efficiency.

[0014] Optionally, the lower part of the storage hole is provided with an arc surface, and the inner sidewall of the storage hole is provided with a guide surface. The storage hole makes the storage film concave through the arc surface and the guide surface.

[0015] By adopting the above technical solution, the arc surface and the guide surface make the storage film concave when the storage film passes through, which facilitates better collection of scale, reduces the possibility of scale falling out of the storage film, and improves cleaning efficiency.

[0016] Optionally, the support base is provided with a film cutting member on the side near the clamping member, the film cutting member being used to cut the storage film.

[0017] By adopting the above technical solution, the film cutting component can easily cut the storage film containing scale, reducing the excessive use of the storage film and improving the overall convenience and practicality of the device.

[0018] Optionally, the support base has a placement groove on the side near the clamping member, and the clamping member is placed in the placement groove.

[0019] By adopting the above technical solution, the placement groove fixes the clamping member, allowing the clamping member to move with the support base and pulling one end of the storage film, which improves the convenience of device operation. At the same time, the placement groove can store the clamping member when it is not in use, reducing the possibility of loss or damage caused by the clamping member being placed randomly.

[0020] Optionally, the support base is provided with a leak-proof block, and the support base is provided with a sealing ring around the leak-proof block. The leak-proof block and the sealing ring are used to seal the connection between the box and the support base.

[0021] By adopting the above technical solution, the cooperation between the leak-proof block and the sealing ring can reduce the possibility of water leakage from the connection between the support base and the tank, thereby improving the reliability and safety of the water outlet tank.

[0022] Optionally, the support base is provided with a locking element, which is used to lock the support base to the housing.

[0023] By adopting the above technical solution, the locking component reliably locks the support base to the housing, reducing the possibility of relative movement between the support base and the housing, which could lead to water leakage from the connection point.

[0024] Optionally, the support base is provided with a slider, and the housing is provided with a sliding groove, with the slider slidably connected to the sliding groove.

[0025] By adopting the above technical solution, a stable and reliable sliding connection is achieved between the support base and the housing, reducing the possibility of the support base shifting during movement.

[0026] Optionally, it also includes a preheating tank, which is used to preheat the water filtered by the filter element; the filter element, the preheating tank and the outlet tank are connected in sequence.

[0027] By adopting the above technical solution, the preheating box can preheat the water filtered by the filter element, reduce the workload of the heating element in the outlet tank, improve the overall heating efficiency and increase the service life of the heating element.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By using a support base to slide the heating element to the cabinet, the scale can be cleaned simply by removing the heating element from the cabinet, reducing the workload of overall disassembly and assembly and reducing water waste;

[0030] 2. After clamping one end of the collection membrane with the clamping device, the membrane unfolds as the support moves, facilitating the collection of scale that falls off during the heating element cleaning process. The collection membrane provides a convenient method for collecting scale, reducing the amount of cleaning work after scale falls off and improving cleaning efficiency;

[0031] 3. By setting curved and guide surfaces, the collection membrane is made concave when it passes through, which makes it easier to collect scale, reduces the possibility of scale falling out of the collection membrane, and improves cleaning efficiency. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0041] This application discloses a dual-tank direct drinking water machine. For example... Figure 1 and Figure 2As shown, the dual-tank direct drinking water machine includes a filter element 9, a preheating tank 2, and a water outlet tank 1. Municipal tap water is filtered by the filter element 9 and then enters the preheating tank 2 for preheating. In the preheating tank 2, the water can be heated to a certain temperature. In this embodiment, the water can be heated to 45 degrees Celsius in the preheating tank 2. After being heated by the preheating tank 2, the water enters the water outlet tank 1 for further heating to 100 degrees Celsius. The preheating tank 2 can preheat the water to a certain temperature, saving the time of heating the water from room temperature to 100 degrees Celsius. When hot water is needed, the direct drinking water machine can supply it quickly, reducing waiting time.

[0042] like Figure 3 As shown, the water outlet tank 1 includes a tank body 101 and a support base 102. A slide rail 1021 is fixedly connected to the support base 102, and a groove 1011 is formed on the tank body 101 to cooperate with the slide rail 1021. Through the cooperation of the slide rail 1021 and the groove 1011, a stable and reliable sliding connection is achieved between the support base 102 and the tank body 101, reducing the possibility of the support base 102 shifting during movement. A heating element 3 is fixedly connected to the support base 102. The heating element 3 can be removed from the tank body 101 for scale cleaning by sliding between the support base 102 and the tank body 101, reducing the workload of overall disassembly and assembly and reducing water waste.

[0043] Meanwhile, in this embodiment, the dual-tank design of the preheating tank 2 and the outlet tank 1 is utilized. The heating tube heats water at a certain temperature to 100 degrees Celsius. Compared with heating from room temperature to 100 degrees Celsius, this reduces the workload of the heating tube in the outlet tank 1, improves the overall heating efficiency, and increases the service life of the heating tube 3.

[0044] like Figure 3 and Figure 4 As shown, a membrane roller 4 is fixedly connected to the housing 101, and a storage membrane 5 is installed on the membrane roller 4. A placement groove 8 is fixedly connected to the side of the support base 102 away from the housing 101, and a clamping member 6 is placed in the placement groove 8. In this embodiment, the clamping member 6 is a long strip-shaped clamp. The clamping member 6 clamps one end of the storage membrane 5 and places it in the placement groove 8. Since the placement groove 8 is fixedly connected to the support base 102, when the sliding support base 102 moves the heating tube 3 out of the housing 101, the clamping member 6 moves with the support base 102 and pulls one end of the storage membrane 5, causing the storage membrane 5 to unfold. After the storage membrane 5 unfolds, it is convenient to collect the scale that falls off during the cleaning of the heating tube 3. The storage membrane 5 provides a convenient way to collect scale, reduces the amount of cleaning work after scale falls off, and improves cleaning efficiency. At the same time, the placement groove 8 can store the clamping member 6 when it is not in use, reducing the possibility of the clamping member 6 being lost or damaged due to random placement.

[0045] In addition, such as Figure 4As shown, a protrusion 801 is fixedly connected inside the placement groove 8. When the clamping member 6 is placed in the placement groove 8, the protrusion 801 abuts against the clamping member 6, making the storage film 5 more securely clamped and improving the stability of the connection between the clamping member 6 and the storage film 5.

[0046] like Figure 5 and Figure 6 As shown, a storage hole 7 is provided on the support base 102, and the storage film 5 is clamped by the clamping member 6 after passing through the storage hole 7. The lower part of the storage hole 7 is provided with an arc surface 701, and the inner sidewall of the storage hole 7 is provided with a guide surface 702.

[0047] It should be noted that after the scale removal from the heating element 3 is completed, the scale falls onto the collection membrane 5 and is collected. At this time, the clamp 6 is removed from the placement slot 8, and while keeping the clamp 6 in place, the support base 102 is moved to return the heating element 3 to the housing 101. During the process of the heating element 3 returning to the housing 101, the collection membrane 5, which has collected the scale, passes through the collection hole 7, causing the scale to move to the side of the support base 102 away from the housing 101, making it easier to clean and thus improving cleaning efficiency. When the collection membrane 5 passes through the collection hole 7, the curved surface 701 allows the collection membrane 5 to maintain a downward-sloping state in the middle under the action of the scale's gravity; the guide surface 702 allows the two sides of the collection membrane 5 to bend closer to the center. Through the curved surface 701 and the guide surface 702, the collection membrane 5 is concave, which can better collect the scale, reduce the possibility of the scale falling out of the collection membrane 5, and improve cleaning efficiency.

[0048] like Figure 3 and Figure 4 As shown, a film-cutting component 12 is also fixedly connected to the support base 102. In this embodiment, the film-cutting component 12 is a blade. After the collecting membrane 5 removes all the scale from the collecting hole 7, the collecting membrane 5 is brought into contact with the film-cutting component 12, so that the portion of the collecting membrane 5 containing scale is cut off, making it easier to dispose of the scale. Using the film-cutting component 12 to cut the collecting membrane 5 reduces the overuse of the collecting membrane 5 and improves the overall convenience and practicality of the device.

[0049] In addition, such as Figure 7 As shown, a leak-proof block 10 is fixedly connected to the support base 102, and a sealing ring 11 is fixedly connected to the periphery of the leak-proof block 10. When the support base 102 moves to abut against the tank body 101, the leak-proof block 10 and the sealing ring 11 can block the connection between the support base 102 and the tank body 101, reducing the possibility of water leakage from the connection and improving the reliability and safety of the water outlet tank 1. Figure 1As shown, a locking element 13 is installed on the support base 102. In this embodiment, the locking element is a bolt. The locking element 13 is used to lock the support base 102 and the housing 101, which reduces the possibility of water leakage from the connection due to relative movement between the support base 102 and the housing 101.

[0050] Furthermore, in this embodiment, the heating element 3 in the outlet tank 1 has a higher heating power and is more prone to scale buildup compared to the heating element 3 in the preheating tank. Therefore, this embodiment descales the heating element 3 in the outlet tank 1. In some other embodiments, the descaling method of this embodiment can also be used for descaling the heating element in the preheating tank.

[0051] The implementation principle of a dual-tank direct drinking water machine according to an embodiment of this application is as follows:

[0052] When descaling the heating element 3 inside the water outlet tank 1 is required, first drain the water from the water outlet tank 1, then slide the support base 102 to move the heating element 3 out of the tank body 101. As the support base 102 moves, the clamping member 6 is located in the placement groove 8, causing the clamping member 6 to move along with the support base 102. With the movement of the clamping member 6, the collecting membrane 5 unfolds under the pull of the clamping member 6. At this point, after the heating element 3 has moved to the appropriate position, scale removal can be performed. The removed scale falls into the collecting membrane 5, facilitating scale removal and improving cleaning efficiency.

[0053] After cleaning, the moving support 102 returns the heating element to the housing 101, while the clamping member 6 is removed from the placement slot 8 and held in place. As the support 102 moves toward the housing 101, the storage membrane 5 passes through the storage hole 7 and removes the scale. As the storage membrane 5 passes through the storage hole 7, the curved surface 701 and the guide surface 702 make the storage membrane 5 concave, better containing the scale and reducing the possibility of scale falling out. After all the scale has been removed from the storage hole 7, the storage membrane 5 is cut using the cutting member. A portion of the storage membrane 5 containing scale is discarded, while the end of the other portion is clamped by the clamping member 6 and placed in the placement slot 8 for future use.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
