Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] The following is combined Figures 1-10 The following describes embodiments of the present invention.

[0034] According to embodiments of this utility model, in one aspect, a high-temperature sterilization system is provided for use in a heat purification and ice-making system, such as... Figure 1 , Figure 2 As shown, the high-temperature disinfection system includes: ice water tank 1, hot water pipeline L1, water inlet pipeline L2, and circulation pipeline L3.

[0035] Ice water tank 1 is used to store ice water and / or ice cubes; hot water pipe L1 is used to prepare hot water and output hot water; water inlet pipe L2 is connected between hot water pipe L1 and ice water tank 1, and water inlet pipe L2 can transport hot water in hot water pipe L1 to ice water tank 1; circulation pipe L3 is connected to ice water tank 1 at both ends, and hot water input into ice water tank 1 by water inlet pipe L2 can be circulated and guided through circulation pipe L3 to perform high-temperature circulation disinfection of ice water tank 1.

[0036] In the above embodiment, a water inlet pipe L2 is set between the hot water pipe L1 and the ice water tank 1 to directly transport the hot water prepared in the heat purification ice-making system to the ice water tank 1. The hot water is circulated and guided through the circulation pipe L3, so that the hot water enters and exits the ice water tank 1 multiple times. This physically disinfects the ice water tank 1 and the pipes on the circulation hot water path by high temperature circulation, ensuring the disinfection effect while avoiding the ice water tank 1 from developing odors or even leaving toxic substances due to improper disinfection.

[0037] Specifically, the hot water source for preparing hot water in the hot water pipe L1 comes from the purified water produced by the purified heating and ice-making system. The hot water pipe L1 serves both as a pipeline for preparing and outputting hot water, and also, after being connected upstream of the outlet of the hot water pipe L1 to the water intake pipe L2, it can also prepare hot water for supplying the ice water tank 1 for high-temperature disinfection. The circulation pipe L3 has an inlet and an outlet. The inlet is connected to the bottom of the ice water tank 1 for circulating water output; the outlet is connected to the top of the ice water tank 1 so that the high-temperature disinfected circulating hot water in the circulation pipe L3 can flow back to the ice water tank 1. This allows for comprehensive and thorough high-temperature disinfection of all heights within the ice water tank 1.

[0038] Furthermore, the hot water pipeline L1 is equipped with a pump body for water transportation and a heating device for heating the water. The water inlet pipeline L2 is connected downstream of the above-mentioned components in the hot water pipeline L1 and located upstream of the water outlet, so that the hot water pipeline L1 can output both hot water and high-temperature disinfection water.

[0039] Furthermore, a self-priming pump can be installed in the water inlet pipe L2 to guide hot water, or a self-priming pump can be installed upstream of the hot water pipe L1 to guide hot water.

[0040] Furthermore, the ice water tank 1 is used only for storing ice water; or, the ice water tank 1 is used only for storing ice cubes; or, the ice water tank 1 is used to store both ice water and ice cubes at the same time. In this case, the ice water tank 1 is configured as a double-layer structure with a partition that can filter water, with the upper layer storing ice cubes and the lower layer storing ice water.

[0041] Furthermore, the ice water and ice blocks stored in the ice water tank 1 can be obtained through the ice-making system in the heat-purifying ice-making system. This embodiment does not limit the specific structural form and ice-making method of the ice-making system.

[0042] In some embodiments, such as Figure 1 , Figure 2 As shown, the high-temperature disinfection system also includes a circulation pump 2 installed in the path of hot water circulation, which is used to guide the hot water in the ice water tank 1.

[0043] In the above embodiment, by setting a circulation pump 2 in the path of water circulation, the hot water in the ice water tank 1 is guided by the circulation pump 2, so that the hot water in the ice water tank 1 can be circulated multiple times between the ice water tank 1 and the circulation pipeline L3, so that the hot water enters and exits the ice water tank 1 multiple times for comprehensive and thorough high-temperature disinfection.

[0044] In this embodiment, the location of the circulation pump 2 is not limited, as long as the circulation pump 2 can guide the hot water in the ice water tank 1. In one implementation, the circulation pump 2 is located in the ice water tank 1; in another implementation, the circulation pump 2 is located in the circulation pipeline L3.

[0045] In some embodiments, such as Figure 1 , Figure 2 As shown, in a preferred embodiment, the circulation pump 2 is installed in the ice water tank 1 and is connected to the inlet of the circulation pipeline L3.

[0046] In the above embodiment, the circulating pump 2 is placed in the ice water tank 1 and connected to the inlet of the circulating pipeline L3. This ensures that the circulating pump 2 circulates and guides the hot water in the ice water tank 1, while also allowing the circulating pump 2 to not occupy space in the heat-purifying ice-making equipment, thus providing more space for the arrangement of components in the heat-purifying ice-making equipment.

[0047] Specifically, the circulation pump 2 is installed in the ice water tank 1 with its outlet connected to the inlet of the circulation pipeline L3. The inlet of the circulation pump 2 is located below the liquid surface of the ice water tank 1. This allows the circulation pump 2 in the ice water tank 1 to draw hot water out of the ice water tank 1 and further into the circulation pipeline L3, and then back into the ice water tank 1 through the circulation pipeline L3, thereby performing high-temperature circulation disinfection on the ice water tank 1.

[0048] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the high-temperature disinfection system also includes a control valve 3 located between the hot water pipe L1 and the water inlet pipe L2. The inlet 301 and the first outlet 302 of the control valve 3 are connected to the hot water pipe L1, and the second outlet 303 of the control valve 3 is connected to the water inlet pipe L2. The control valve 3 can adjust the opening and closing of the first outlet 302 and the second outlet 303.

[0049] In the above embodiment, the control valve 3 located between the hot water pipe L1 and the water inlet pipe L2 is used to adjust the output section of the hot water pipe L1 and the on / off state of the water inlet pipe L2, so as to switch the output hot water mode and the output high temperature disinfection water mode of the hot water pipe L1.

[0050] Specifically, such as Figure 1As shown, control valve 3 regulates the opening and closing of the corresponding pipelines by adjusting the opening and closing of the first outlet 302 and the second outlet 303. In hot water output mode, the first outlet 302 of control valve 3 is open and the second outlet 302 is closed. At this time, the hot water prepared in hot water pipeline L1 is directly supplied to the user through the output section of hot water pipeline L1. In high-temperature disinfection water mode, the second outlet 303 of control valve 3 is open and the first outlet 302 is closed. At this time, the hot water prepared in hot water pipeline L1 is transported to the ice water tank 1 through the water inlet pipeline L2 for high-temperature circulation disinfection.

[0051] Furthermore, such as Figure 1 As shown, the control valve 3 is a three-channel solenoid valve, which automatically opens and closes the first outlet 302 and the second outlet 303 through electrical control.

[0052] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the high-temperature disinfection system also includes a heating element 4 installed in the hot water pipe L1. The heating element 4 is used to heat the water from the upstream of the hot water pipe L1, and the control valve 3 is installed downstream of the heating element 4.

[0053] In the above embodiment, the control valve 3 is located downstream of the heating element 4 to ensure that heated water is output to the water inlet pipe L2 and the ice water tank 1 so as to supply the ice water tank 1 for high-temperature circulation disinfection.

[0054] Specifically, the water from upstream of the hot water pipe L1 is room temperature water stored in the pure water tank 7. When the room temperature water flows through the heating element 4, it is heated by the heating element 4 to prepare hot water for output or for output of high-temperature disinfection water.

[0055] In some embodiments, such as Figure 1 , Figure 4 As shown, the high-temperature disinfection system also includes an ice water pipeline L4 connected to the ice water tank 1. The ice water pipeline L4 is equipped with a self-priming pump 5. The self-priming pump 5 can output ice water from the ice water tank 1 through the ice water pipeline L4, or the self-priming pump 5 can output hot water from the ice water tank 1 after high-temperature disinfection through the ice water pipeline L4.

[0056] In the above embodiment, an ice water pipeline L4 connected to the ice water tank 1 is provided and a self-priming pump 5 is installed on it to facilitate the user to take ice water; at the same time, it can also drain the hot water that has been disinfected at high temperature in the ice water tank 1 in a timely manner.

[0057] Specifically, when a user needs to obtain ice water, the ice water extraction program can be started, and the self-priming pump 5 will draw ice water from the ice water tank 1 through the pipes and the outlet. After the high-temperature circulation disinfection of the ice water tank 1 is completed, the drainage program can be started, and the self-priming pump 5 will drain the hot water from the ice water tank 1 that has completed the high-temperature circulation disinfection through the pipes and the outlet.

[0058] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 As shown, the high-temperature disinfection system also includes a water circuit board 6; at least a portion of the hot water pipe L1 is formed inside the water circuit board 6, and the hot water outlet 601 at the end of the hot water pipe L1 is formed inside the water circuit board 6; at least a portion of the water inlet pipe L2 is formed inside the water circuit board 6, and the ice water tank interface 602 at the end of the water inlet pipe L2 is formed inside the water circuit board 6, and the ice water tank interface 602 is connected to the ice water tank 1 through a flexible hose; at least a portion of the ice water pipe L4 is formed inside the water circuit board 6, and the ice water outlet 603 at the end of the ice water pipe L4 is formed inside the water circuit board 6.

[0059] In the above embodiments, the water circuit board 6 adopts an integrated water circuit board module and a modular design, which not only improves the sealing and stability of the high-temperature disinfection system, but also simplifies the assembly process and improves the production efficiency of the high-temperature disinfection system. Furthermore, the modular design of the high-temperature disinfection system makes the maintenance and upgrading of the heat-purifying ice-making equipment more convenient, while also solving the problems of odor, complex assembly, and low safety caused by messy pipelines in traditional heat-purifying ice-making equipment using silicone tubing.

[0060] Specifically, in the hot water pipeline L1, the section downstream of control valve 3 is formed inside the water circuit board 6. In the water inlet pipeline L2, the section near control valve 3 is formed inside the water circuit board 6, while the section away from control valve 3 is a flexible hose. One end of the flexible hose is connected to the chilled water tank interface 602, and the other end is connected to the chilled water tank 1. In the chilled water pipeline L4, the section near the chilled water tank 1 is the aforementioned flexible hose, while the section away from the chilled water tank 1 is formed inside the water circuit board 6. Thus, the flexible hose has a triple function: firstly, as the downstream section of the water inlet pipeline L2, it is used to introduce hot water into the chilled water tank 1 for high-temperature circulation disinfection, or to replenish water for users to make chilled water or ice cubes; secondly, as the upstream section of the chilled water pipeline L4, it is used to guide the chilled water used by users.

[0061] Furthermore, the water circuit board 6 has a hot water outlet 601 located at the end of the hot water pipe L1 and an ice water outlet 603 located at the end of the ice water pipe L4. The high-temperature disinfection system also includes a water outlet 9, which has a hot water pipe section and an ice water pipe section. The hot water pipe section is connected to the hot water outlet 601, and the ice water pipe section is connected to the ice water outlet 603. As an alternative implementation, two water outlets, namely a hot water outlet and an ice water outlet, are provided, which are connected to the hot water outlet 601 and the ice water outlet 603, respectively.

[0062] In some embodiments, such as Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the water circuit board 6 is also provided with a first valve connector 604 connected to the hot water pipe L1, a second valve connector 605 connected to the water inlet pipe L2, a self-priming pump inlet connector 606 connected to the chilled water pipe L4, and a self-priming pump outlet connector 607; the first outlet 302 of the control valve 3 is connected to the first valve connector 604, and the second outlet 303 of the control valve 3 is connected to the second valve connector 605; the inlet end of the self-priming pump 5 is connected to the self-priming pump inlet connector 606, and the outlet end of the self-priming pump 5 is connected to the self-priming pump outlet connector 607; the self-priming pump inlet connector 606 is connected to the chilled water tank connector 602. In the above embodiments, several plug interfaces corresponding to the corresponding pipelines are provided in the water circuit board 6 so as to facilitate the stable and convenient installation of structural components such as control valve 3 and self-priming pump 5 on the upper water circuit board 6.

[0063] Specifically, the hose connecting the chilled water tank 1 is shared by the water inlet pipe L2 and the chilled water pipe L4. Therefore, the self-priming pump inlet port 606 is connected to the chilled water tank port 602. This arrangement is to facilitate the following: during high-temperature circulating sterilization, hot water flows from the section of the water inlet pipe L2 in the water circuit board 6 through the chilled water tank port 602 to the hose and the chilled water tank 1; when chilled water is used, chilled water flows from the chilled water tank 1 and the hose through the chilled water tank port 602 to the self-priming pump inlet port 606 in the water circuit board 6, and then flows to the self-priming pump 5 and the section of the chilled water pipe L4 in the water circuit board 6.

[0064] In some embodiments, such as Figure 1 , Figure 6 As shown, the heating element 4 has a water inlet port 401 and a water outlet port 402. The water outlet port 402 and the inlet 301 of the control valve 3 are respectively inserted into the adapter 10.

[0065] The high-temperature disinfection system also includes: a pure water tank 7 and a normal temperature water pipeline L5.

[0066] The pure water tank 7 is used to store room temperature water; one end of the room temperature water pipe L5 is connected to the pure water tank 7, and the other end is connected to the water inlet port 401 of the heating element 4.

[0067] In the above embodiment, the adapter 10 serves as an intermediate connection between the heating element 4 and the control valve 3, avoiding the need for connection via hoses or silicone tubes, thus improving assembly convenience. Room temperature water is supplied to the heating element 4 via the pure water tank 7 and the room temperature water pipeline L5, facilitating the heating of the room temperature water into hot water for users to use or for high-temperature circulating disinfection.

[0068] Specifically, the heating element 4 is vertically oriented. The adapter 10 is located on one side of the heating element 4. The adapter 10 has a pipeline and is connected to the pipeline, and has two insertion ports corresponding to the water outlet port 402 of the heating element 4 and the inlet 301 of the control valve 3, respectively. At the same time, the adapter 10 also provides support for the water circuit board 6 and stably installs the water circuit board 6 and the structural components such as the control valve 3, the self-priming pump 5, and the heating element 4 mounted on it in the clean heat ice-making equipment.

[0069] Furthermore, a self-priming pump is installed in the ambient temperature water pipeline L5 to guide the ambient temperature water.

[0070] In some embodiments, such as Figure 10 As shown, the high-temperature disinfection system also includes a boiled water heat exchanger 8 with a heat exchange inlet 801 and a heat exchange outlet 802. The boiled water heat exchanger 8 is used to regulate the water temperature of the hot water. The water circuit board 6 is provided with a heat exchanger inlet port 608 and a heat exchanger outlet port 609 that are connected to the hot water pipeline L1. The heat exchange inlet 801 is plugged into the heat exchanger inlet port 608, and the heat exchange outlet 802 is plugged into the heat exchanger outlet port 609.

[0071] In the above embodiment, a hot water heat exchanger 8 is provided to adjust the temperature of the hot water, thereby using the principle of heat exchange to output hot water at the temperature required by the user as set by the system.

[0072] Specifically, the heat exchanger inlet port 608 and the heat exchanger outlet port 609 are respectively connected to the hot water pipeline L1. After being heated by the heating element 4, the hot water enters the hot water pipeline L1 and first enters the boiled water heat exchanger 8 through the heat exchange inlet 801 via the heat exchanger inlet port 608. After heat exchange treatment by the boiled water heat exchanger 8, the water at the appropriate temperature flows out of the boiled water heat exchanger 8 through the heat exchange outlet 802 and returns to the hot water pipeline L1 through the heat exchanger outlet port 609. Finally, it flows out from the hot water outlet 601 at the end of the hot water pipeline L1 for the user to use.

[0073] According to an embodiment of the present invention, another aspect provides a drinking water device, including the high-temperature disinfection system described in the above embodiment.
