[0056] like Figures 1 to 11 As shown, this embodiment of the invention provides a water purification component 100 and a refrigeration device.

[0057] like Figures 1 to 7 As shown, a first aspect of the present invention provides a water purification component 100, which is used to install in the cold storage compartment 700 of a refrigeration equipment. The water purification component 100 has a first water inlet and a second water inlet, and further includes an inner shell 13, an outer shell 14, and a water filtration unit 15. One of the first water inlet and the second water inlet is a water inlet 11, and the other of the first water inlet and the second water inlet is a water outlet 12.

[0058] The inner shell 13 is disposed within the outer shell 14, and the inner wall surface of the outer shell 14 is spaced apart from the outer wall surface of the inner shell 13 to define a first water passage 101 between the inner wall surface of the outer shell 14 and the outer wall surface of the inner shell 13. In this embodiment, both the inner shell 13 and the outer shell 14 can be made of thermally conductive materials such as copper, aluminum, or stainless steel to facilitate heat exchange between the water in the water purification component 100 and the low-temperature air in the cold storage compartment 700.

[0059] Furthermore, the water filtration unit 15 shown in this embodiment is disposed in the inner shell 13, and a flow guide 16 is provided between the outer wall surface of the inner shell 13 and the inner wall surface of the outer shell 14. The flow guide 16 further defines a first flow channel within the first water passage 101; the first water inlet, the first flow channel, the inner shell and the second water inlet are connected in sequence.

[0060] In this embodiment, the first guide channel is used to guide the water to flow along its extension direction. The form of the first guide channel depends on the arrangement of the guide members 16 between the outer wall of the inner shell 13 and the inner wall of the outer shell 14. The first guide channel can be a straight channel extending axially along the inner shell 13, or a spiral channel extending in a spiral shape relative to the central axis of the inner shell 13; no specific limitation is made here.

[0061] Specifically, this embodiment optimizes the water flow path within the water purification component 100. Alternatively, the water can be filtered first, and then the filtered purified water is guided through the first guide channel and discharged from the outlet 12. Or, the water can be transported through the first guide channel first, then filtered, and finally discharged from the outlet 12. In this embodiment, the first water inlet, first guide channel, inner shell, and second water inlet do not need to be arranged sequentially; it is sufficient that the water can flow along the first water inlet, first guide channel, inner shell, and second water inlet in that order.

[0062] In this embodiment, based on the setting of the first flow channel, the flow of water can be guided. While ensuring the flow time of the water, it can also prevent the problem of muddy water during the flow to a certain extent. When the water purification component 100 is applied in the cold storage compartment 700 of the refrigeration equipment, it can supply purified water that has been cooled to the water-using devices, thus realizing the integration of water purification function and anti-muddling function.

[0063] In some embodiments, in order to ensure the anti-mixing effect and to ensure the first-in-first-out of water, the first guide channel shown in this embodiment is preferably a spiral channel.

[0064] Specifically, in this embodiment, the inner shell 13 and the outer shell 14 are coaxially arranged, and the flow guide 16 extends in a spiral shape relative to the central axis of the inner shell 13, so that the first flow guide channel is formed as a spiral flow channel.

[0065] In this embodiment, based on the design of the flow guide 16, on the one hand, a radial support is formed between the inner shell 13 and the outer shell 14, and on the other hand, a spiral flow channel can be formed between the inner shell 13 and the outer shell 14. After the water enters the spiral flow channel, it can only flow along the extension direction of the spiral flow channel. During the process of the water flowing along the spiral flow channel, the water is first-in, first-out. When the water purification component 100 vibrates or operates due to external force, the water will not flow back in the spiral flow channel, thereby reducing the turbidity inside the flow channel.

[0066] In this embodiment, the flow guide 16 can be disposed on the inner wall surface of the outer shell 14, the outer wall surface of the inner shell 13, or sandwiched between the inner wall surface of the outer shell 14 and the outer wall surface of the inner shell 13.

[0067] In some embodiments, the axial length of the guide member 16 extending relative to the central axis of the inner shell 13 may be less than the axial length of the inner shell 13. For example, the axial length of the guide member 16 extending relative to the central axis of the inner shell 13 may be equal to (50% to 75%) of the axial length of the inner shell 13.

[0068] To further enhance the anti-mixing effect, this embodiment can also set the axial length of the flow guide 16 relative to the central axis of the inner shell 13 to be equal to the axial length of the inner shell 13, so as to achieve the maximum design of the spiral flow channel while achieving anti-mixing.

[0069] In practical applications, such as Figure 3 and Figure 4 As shown, when the first water outlet is used as the water inlet 11 and the second water outlet is used as the water outlet 12, the water inlet 11 shown in this embodiment is connected to one end of the first guide channel, the other end of the first guide channel is connected to the inner shell 13, and the inner shell 13 is connected to the water outlet 12.

[0070] Thus, after the water enters the first guide channel through the inlet 11, the first guide channel guides the water into the inner shell 13. The water filtration unit 15 is used to filter the water in the inner shell 13, and the filtered purified water is discharged from the outlet 12.

[0071] Here, the first flow channel shown in this embodiment extends the internal water path of the water purification component 100. Under the low-temperature environment provided by the cold storage room 700, there is sufficient time to cool the water entering the water purification component 100, and then the cooled water is filtered. The filtered purified water is then discharged from the outlet 12, thereby facilitating the supply of cooled purified water to water-using devices.

[0072] In practical applications, such as Figure 5 and Figure 6 As shown, when the first water outlet is used as the water inlet 11 and the second water outlet is used as the water outlet 12, the water inlet 11 in this embodiment is connected to the inner shell 13, the inner shell 13 is connected to the other end of the first guide channel, and one end of the first guide channel is connected to the water outlet 12.

[0073] Thus, after the water enters the inner shell 13 through the inlet 11, the water filtration unit 15 filters the water. The purified water output by the water filtration unit 15 enters the first guide channel from the inner shell 13, and the first water passage 101 guides the purified water to be discharged from the outlet 12.

[0074] Compared to existing water purifiers, when the water purification component 100 of this embodiment is placed in the cold storage compartment 700 of the refrigeration equipment, the water entering the water purification component 100 is first filtered into purified water by the water filtration unit 15. After the purified water enters the first water passage 101, based on the extension effect of the first water passage 101 on the internal water path of the water purification component 100, there is sufficient time to cool the purified water in the low temperature environment provided by the cold storage compartment 700. The cooled purified water is then discharged from the water inlet 11, thereby facilitating the supply of cooled purified water to water-using devices.

[0075] In some embodiments, in order to increase the water flow path within the water purification assembly 100, one end of the first guide channel is formed between the outer wall surface of the first end of the inner shell 13 and the inner wall surface of the outer shell 14, and communicates with the first water inlet. The other end of the first guide channel is between the outer wall surface of the second end of the inner shell 13 and the inner wall surface of the outer shell 14, and communicates with the inner shell 13.

[0076] Furthermore, in this embodiment, the other end of the first flow channel can be connected to the second end of the inner shell 13, and the second water inlet is formed at the first end of the inner shell 13.

[0077] In some examples, such as Figure 3 and Figure 4 As shown, when the first water outlet serves as the inlet 11 and the second water outlet serves as the outlet 12, the water flows into the inner shell 13 along the first guide channel, then flows from the second end of the inner shell 13 to the first end. During this process, the water is filtered by the filter unit 15, and the purified water is output towards the first end of the inner shell 13, finally being discharged through the outlet 12. Figure 3 and Figure 4 The arrows in the middle indicate the direction of water flow.

[0078] Since the first flow channel is formed between the opposing walls of the inner shell 13 and the outer shell 14, and the water filter unit 15 is disposed in the inner shell 13, the water in the first flow channel is initially cooled under the condition of air convection heat exchange between the outer shell 14 and the cold storage compartment 700. The cooling capacity of the water in the first flow channel can also be further conducted to the inner shell 13 through the inner shell 13 to cool the water in the inner shell 13 again, thereby ensuring the effect of cooling the water.

[0079] In some examples, such as Figure 3 and Figure 4 As shown, in this embodiment, a first sleeve is provided at the first end of the outer shell 14, and a second sleeve is provided at the first end of the inner shell 13. The second sleeve is inserted into the first sleeve. The inner wall surface of the first sleeve and the outer wall surface of the second sleeve form an inlet 11, and the second sleeve forms an outlet 12.

[0080] Here, the connector 200 typically includes a first water inlet, a second water inlet, and an adapter. The first water inlet and the second water inlet are respectively connected to the adapter. Thus, by connecting one end of the first sleeve to the adapter, the first water inlet can be connected to the inlet 11, and the outlet 12 can be connected to the second water inlet.

[0081] Meanwhile, in actual installation, one end of the first sleeve shown in this embodiment is detachably connected to the adapter to facilitate the replacement and maintenance of the water filter unit 15 inside the water purification component 100.

[0082] In some examples, such as Figure 5 and Figure 6 As shown, when the first water outlet serves as the inlet 11 and the second water outlet serves as the outlet 12, water enters the inner shell 13 from the inlet 11 at the first end of the inner shell 13. After being filtered by the water filtration unit 15, the purified water is output towards the second end of the inner shell 13 into the first guide channel shown in the above embodiment, and discharged from the outlet 12 under the guidance of the first guide channel. Figure 5 and Figure 6The arrows in the middle indicate the direction of water flow.

[0083] As can be seen from the above, the flow direction of the water in the inner shell 13 is exactly opposite to the flow direction of the water in the first guide channel. This not only makes effective use of the internal space of the water purification component 100 and maximizes the water flow path, but also facilitates heat exchange between the water inside and outside the inner shell 13, ensuring the cooling effect of the water inside the water purification component 100.

[0084] In some embodiments, such as Figure 3 and Figure 6 As shown, in order to achieve the integrated design of water purification component 100 with water purification and water storage functions, the inner shell 13 shown in this embodiment is provided with a filter chamber 131 and a water storage chamber 132, which are connected; a second water outlet is formed at the first end of the inner shell 13 and is connected to the filter chamber 131, and the water filtration unit 15 is disposed in the filter chamber 131; the first flow channel is connected to the water storage chamber 132 through the second end of the inner shell 13.

[0085] To facilitate the installation of the water filter unit 15, the first end of the water filter unit 15 shown in this embodiment abuts against the first end of the inner shell 13; a support member 17 is provided in the water storage cavity 132, and the support member 17 supports the second end of the water filter unit 15.

[0086] Specifically, in this embodiment, the second end of the inner shell 13 is open and the second end of the outer shell 14 is closed. While one end of the support member 17 is supported on the second end of the water filter unit 15, this embodiment can also have the other end of the support member 17 abut against the second end of the outer shell 14.

[0087] Since the first end of the water filtration unit 15 abuts against the first end of the inner shell 13, and the support member 17 supports the first end of the water filtration unit 15, based on the supporting role of the support member 17, in this embodiment, the second end of the inner shell 13 and the second end of the outer shell 14 can also be spaced apart to form a flow guide gap between the second end of the inner shell 13 and the second end of the outer shell 14, and the other end of the first flow guide channel is connected to the water storage cavity 132 through the flow guide gap.

[0088] In this embodiment, the support member 17 includes multiple arc-shaped support plates, which are arranged in a cylindrical shape along the circumference relative to the central axis of the inner shell 13, so as to support the second end of the water filtration unit 15.

[0089] Thus, the support member 17 shown in this embodiment not only provides stable support for the water filtration unit 15, but also does not occupy too much of the internal space of the water storage chamber 132.

[0090] In some embodiments, the support member 17 divides a second flow channel within the water storage cavity 132. The second flow channel is used to guide water to flow between one end of the filter cavity 131 and the second end of the inner shell 13 along the extension direction of the second flow channel.

[0091] In some examples, the support 17 can be a spiral member, so that the second guide channel is formed as a spiral channel, which can guide the water to flow in a directional manner along the extension direction of the spiral channel, avoiding the problem of turbidity of the water during the flow.

[0092] In some examples, the support member 17 may also be composed of multiple arc-shaped support plates as shown in the above embodiments, so that the second flow channel shown in this embodiment extends along the axial direction of the inner shell 13. Thus, the second flow channel is used to guide the water to flow in an axial direction along the inner shell 13. While storing water based on the second flow channel, it also realizes the first-in-first-out of water and plays the role of preventing water mixing.

[0093] In some examples, in order to ensure that the end of the support member 17 facing the water filter unit 15 provides stable support for the water filter unit 15, this embodiment provides a positioning structure at the second end of the water filter unit 15. For example, the positioning structure is a positioning groove or a positioning block, and the positioning structure is adapted to the end of the support member 17 facing the water filter unit 15.

[0094] In some examples, to facilitate the installation of the water filter unit 15, this embodiment forms the second end of the water filter unit 15 and the support member 17 into an integral structure.

[0095] In some examples, such as Figure 4 and Figure 5 As shown in the figure, the second end of the outer shell 14 in this embodiment is closed, and the second end of the inner shell 13 is open; the second end of the inner shell 13 is spaced apart from the second end of the outer shell 14, and a water storage cavity 132 is formed between the second end of the inner shell 13 and the second end of the outer shell 14, and the other end of the first guide channel is connected to the water storage cavity 132.

[0096] In this embodiment, when installing the support member 17, after the first end of the water filter unit 15 abuts against the first end of the inner shell 13, one end of the support member 17 can abut against the second end of the water filter unit 15 and the second end of the inner shell 13 respectively. After installing the cover 141 on the second end of the outer shell 14, the other end of the support member 17 abuts against the second end of the outer shell 14. The arrangement of the water storage cavity 132 is achieved based on the support gap between the second end of the inner shell 13 and the second end of the outer shell 14, and the water storage cavity 132 is arranged on the outside of the inner shell 13.

[0097] In order to facilitate the installation of the support member 17, in this embodiment, one end of the support member 17 and the second end of the water filtration unit 15 can be designed as an integral structure.

[0098] In some embodiments, such as Figures 3 to 7 As shown, the water filtration unit 15 in this embodiment includes a filter element 151; a second water passage 102 is formed between the side of the filter element 151 and the inner wall of the inner shell 13, and a clean water flow channel is provided inside the filter element 151, which is connected to the first water passage 101.

[0099] The filter element 151 can be either an activated carbon rod filter element 151 or a filter element 151 made of reverse osmosis membrane, which is known in the art. The filter element 151 is used to filter the water that enters the purified water channel from the second water passage 102.

[0100] In the water purification process, this embodiment sets up a second water passage 102 to ensure that the water in the inner shell 13 first enters the second water passage 102 and is then filtered by the filter element 151 to achieve water purification.

[0101] In some embodiments, such as Figure 7 As shown, the water filtration unit 15 in this embodiment also includes a first cover 152 and a second cover 153; the first cover 152 is encapsulated at one end of the filter element 151, the second cover 153 is encapsulated at the other end of the filter element 151, and the second cover 153 is connected to the support member 17 shown in the above embodiment, or the second cover 153 and the support member 17 shown in the above embodiment are integrated into one structure.

[0102] In some examples, such as Figure 3 and Figure 4 As shown, when the first water outlet is used as the inlet 11 and the second water outlet is used as the outlet 12, the first cover 152 shown in this embodiment has a first positioning groove on one side facing the filter element 151. One end of the filter element 151 is inserted into the first positioning groove. The center of the first cover 152 facing the filter element 151 has a first extension. The first extension is adapted to be inserted into one end of the clean water flow channel. The first extension has a clean water outlet that passes through the filter element 151 along its axial direction.

[0103] Meanwhile, the second cover 153 shown in this embodiment has a second positioning groove on one side facing the filter element 151, and the other end of the filter element 151 is inserted into the second positioning groove. The center of the second cover 153 facing the filter element 151 has a second extension, which is adapted to be inserted into the other end of the water purification channel to block the other end of the water purification channel.

[0104] In some examples, such as Figure 5 and Figure 6As shown, when the first water outlet is used as the inlet 11 and the second water outlet is used as the outlet 12, the first cover 152 shown in this embodiment has a first positioning groove on one side facing the filter element 151. One end of the filter element 151 is inserted into the first positioning groove. The center of the first cover 152 facing the filter element 151 has a first extension. The first extension is adapted to be inserted into one end of the purified water channel to block one end of the purified water channel.

[0105] Meanwhile, the second cover 153 shown in this embodiment has a second positioning groove on one side facing the filter element 151, and the other end of the filter element 151 is inserted into the second positioning groove. The center of the side of the second cover 153 facing the filter element 151 has a second extension, which is adapted to be inserted into the other end of the water purification channel. The second extension has a water purification outlet that passes through the filter element 151 along its axial direction.

[0106] In some examples, this embodiment may provide a positioning structure on the side of the second cover 153 facing away from the filter element 151. For example, the positioning structure may be a positioning groove or a positioning protrusion. The positioning structure is adapted to the end of the support member 17 facing the water filtration unit 15 shown in the above embodiment to ensure the reliability of the support member 17 in supporting the water filtration unit 15.

[0107] In some examples, in order to facilitate the installation of the water filtration unit 15, the second cover 153 and the support member 17 can also be designed as an integral structure.

[0108] In some embodiments, such as Figure 8 and Figure 9 As shown, the water purification component 100 shown in this embodiment further includes a water-stopping structure 18, which includes a water-stopping component 181 and a water-stopping channel 182 constructed at the first end of the outer shell 14. The water-stopping component 181 is connected to the first end of the inner shell 13. The water-stopping component 181 is movably disposed in the water-stopping channel 182. The water-stopping component 181 has an inlet channel 81 and an outlet channel 82.

[0109] The inner wall of the water-stop channel 182 and the outer wall of the water-stop component 181 form the water inlet 11 shown in the above embodiment. The water inlet end of the water inlet channel 81 and the water outlet end of the water outlet channel 82 are respectively constructed on the outer wall of the water-stop component 181. The water outlet end of the water inlet channel 81 is connected to the inner shell 13, and the water outlet end of the water outlet channel 82 is formed as the water outlet 12 shown in the above embodiment.

[0110] The water-stopping structure 18 has a first mating state and a second mating state. When the water-stopping structure 18 is in the first mating state, the water-stopping component 181 moves to the blocking position of the water-stopping channel 182, and the water inlet end of the water inlet channel 81 and the water inlet end of the water outlet channel 82 are blocked, so that the water inlet 11 is blocked from the water inlet channel 81, and the first water passage 101 where the first guide channel is located is blocked from the water outlet channel 82.

[0111] When the water-stopping structure 18 is in the second mating state, the water-stopping component 181 moves to the connection position of the water-stopping channel 182, and the water inlet end of the water inlet channel 81 and the water inlet end of the water outlet channel 82 are open, so that the water inlet 11 is connected to the water inlet channel 81, and the first water passage 101 where the first guide channel is located is connected to the water outlet channel 82.

[0112] According to the embodiment of the present invention, the water-stopping structure 18, by constructing an inlet channel 81 and an outlet channel 82 in the water-stopping member 181, when the water-stopping structure 18 is in the first engagement state, the water-stopping member 181 moves to the blocking position of the water-stopping channel 182, and the water-stopping channel 182 blocks the inlet channel 81 and the outlet channel 82, so as to avoid the problem of internal water flowing out when the water filter unit 15 of the water purification component 100 is pulled out and replaced, and facilitates the installation and maintenance of the water purification component 100.

[0113] In practical applications, the water-stopping structure 18 provided in this embodiment is detachably connected to the connector 200. When it is found that the filter element 151 needs to be pulled out and replaced, the connector 200 can be separated from the water-stopping structure 18. At this time, the water-stopping structure 18 is in the first mating state, and the water-stopping component 181 is moved to the blocking position of the water-stopping channel 182. Figure 8 As shown, the water-stopping component 181 moves upward relative to the water-stopping channel 182. Since the water inlet and outlet of the water-stopping component 181 are blocked, the water in the water purification component 100 cannot flow out from its inlet 11 and outlet 12, thereby realizing the water-stopping function of the water-stopping structure 18.

[0114] When the water-stop structure 18 is installed on the connector 200, the water-stop structure 18 is in the second mating state, and the water-stop component 181 moves to the communication position of the water-stop channel 182. At this time, the water-stop component 181 moves downward relative to the water-stop channel 182, and the water inlet and water outlet on the water-stop component 181 are exposed. The water flow from the first water inlet on the connector 200 can flow into the inner shell 13 in sequence through the water inlet 11 and the water inlet channel 81. The water in the first water passage 101 can also flow to the second water inlet of the connector 200 through the water outlet channel 82.

[0115] In some embodiments, such as Figure 7 and Figure 8As shown, the water-stopping structure 18 in this embodiment further includes a first sealing ring 1811, a second sealing ring 1812, and a third sealing ring 1813, which are sequentially and spaced apart between the outer wall surface of the water-stopping member 181 and the inner wall surface of the water-stopping channel 182 along the direction of movement of the water-stopping member 181. For example, in this embodiment, the water-stopping member 181 can move up and down relative to the water-stopping channel 182. Therefore, the first sealing ring 1811, the second sealing ring 1812, and the third sealing ring 1813 are sequentially and spaced apart from top to bottom on the water-stopping member 181. The first sealing ring 1811, the second sealing ring 1812, and the third sealing ring 1813 are all located between the water-stopping member 181 and the water-stopping channel 182. The first sealing ring 1811, the second sealing ring 1812, and the third sealing ring 1813 can be rubber rings.

[0116] In this embodiment, the water inlet end of the water inlet channel 81 is located between the first sealing ring 1811 and the second sealing ring 1812; the water outlet end of the water outlet channel 82 is located between the second sealing ring 1812 and the third sealing ring 1813. That is, the water inlet end of the water inlet channel 81 is located above the water outlet end of the water outlet channel 82.

[0117] It should be noted that in other embodiments, the first sealing ring 1811, the second sealing ring 1812, and the third sealing ring 1813 may be sequentially and alternately fitted onto the water-stopping member 181 from bottom to top. That is, the water inlet end of the water inlet channel 81 is located below the water outlet end of the water outlet channel 82.

[0118] like Figure 8 As shown, the inner wall of the water-stop channel 182 is provided with a first protrusion 1821, which is an annular protrusion.

[0119] When the water-stopping structure 18 is in the first mating state, the water-stopping member 181 moves upward relative to the water-stopping channel 182, and the water-stopping member 181 moves to the blocking position of the water-stopping channel 182. At this time, the first sealing ring 1811 abuts against the first protrusion 1821, and the first sealing ring 1811 forms a first sealing surface at the first protrusion 1821. The second sealing ring 1812 forms a second sealing surface on the inner wall surface of the water-stopping channel 182, and the third sealing ring 1813 forms a third sealing surface on the inner wall surface of the water-stopping channel 182, so that the water inlet end of the water inlet channel 81 is in the blocking channel formed between the first sealing ring 1811 and the second sealing ring 1812, and the water inlet end of the water outlet channel 82 is in the blocking channel formed between the second sealing ring 1812 and the third sealing ring 1813, thereby realizing the water-stopping function of the water-stopping structure 18.

[0120] When the water-stop structure 18 is in the second mating state, the water-stop member 181 moves downward relative to the water-stop channel 182, moving to the communication position of the water-stop channel 182. The first sealing ring 1811 disengages from the first protrusion 1821, the second sealing ring 1812 forms a second sealing surface on the inner wall surface of the water-stop channel 182, and the third sealing ring 1813 disengages from the inner wall surface of the water-stop channel 182, so that the water-stop member 181 and the water-stop channel 182 form a flow guiding gap at the position where the first sealing ring 1811 is located, and the water-stop member 181 and the water-stop channel 182 form a flow guiding gap at the position where the third sealing ring 1813 is located, thereby realizing the conduction function of the water-stop structure 18.

[0121] It should be noted that the water-stopping component 181 shown in this embodiment includes a water-stopping section and a fixing section. One end of the water-stopping section is connected to one end of the fixing section, and the other end of the fixing section is connected to the first end of the inner shell 13.

[0122] In this embodiment, the water-stopping section is constructed with an inlet channel 81 and an outlet channel 82; the inlet end of the inlet channel 81 and the outlet end of the outlet channel 82 are respectively constructed on the side wall of the water-stopping section; the outlet end of the inlet channel 81 extends to the fixed section and communicates with the water inlet at the first end of the inner shell 13 through the inner cavity of the fixed section; the outlet end of the outlet channel 82 is constructed at the other end of the water-stopping section.

[0123] In some examples, the diameter of the fixed section shown in this embodiment is larger than the diameter of the water-stopping section, and the other end of the fixed section is connected to the first end of the inner shell 13 via an elastic element 183. The elastic element 183 can be a spring known in the art.

[0124] In practical applications, when the water-stopping structure 18 is in the first engagement state, the elastic element 183 is in the first state, and the water-stopping member 181 moves to the blocking position of the water-stopping channel 182 under the drive of the elastic element 183. When the water-stopping structure 18 is in the second engagement state, the elastic element 183 is in the second state, and the water-stopping member 181 moves to the connecting position of the water-stopping channel 182 under the action of external force. The deformation of the elastic element 183 in the second state is greater than the deformation of the elastic element 183 in the first state.

[0125] Thus, after the water-stopping structure 18 is removed from the connector 200, since the water-stopping component 181 is no longer subjected to the resistance from the connector 200, the elastic element 183 will return from the second state to the first state. During the process of restoring its deformation, the elastic element 183 will drive the water-stopping component 181 to move to the blocking position of the water-stopping channel 182, so as to realize the water-stopping function of the water-stopping structure 18. This avoids the problem of internal water flowing out when the staff removes the water purification component 100 from the connector 200, and improves the user's experience of replacing the water filter unit 15.

[0126] like Figure 10 and Figure 11 As shown, a second aspect of the present invention provides a refrigeration device, including a cold storage compartment 700 and a water-using component, and further including a water purification component 100 as described above installed in the cold storage compartment 700, wherein the water outlet 12 of the water purification component 100 is connected to the water-using device.

[0127] In practical applications, the refrigeration equipment shown in this embodiment is equipped with a water supply pipeline. One end of the water supply pipeline is used for connection to the water supply system (tap water network), and the other end of the water supply pipeline extends into the cold storage room 700.

[0128] In this embodiment, the water inlet 11 of the water purification component 100 is connected to the other end of the water supply pipeline. Since the water purification component 100 is located in the cold storage room 700, the water entering the water purification component 100 can be filtered and then cooled in the low-temperature environment of the cold storage room 700, and the low-temperature purified water output by the water purification component 100 is supplied to the water-using devices.

[0129] Furthermore, in this embodiment, by setting a water storage chamber 132 inside the water purification component 100, the existing water tank structure and the water purifier are integrated into one unit, thereby simplifying the water supply circuit structure of the water-using device.

[0130] In some embodiments, when multiple water-using devices are provided, the refrigeration equipment shown in this embodiment is further provided with a liquid distribution valve 300; the liquid distribution valve 300 includes a liquid inlet and multiple liquid outlets, the water outlet 12 of the water purification component 100 is connected to the liquid inlet, and the multiple liquid outlets are connected to multiple water-using devices one by one.

[0131] Therefore, based on the design of the liquid distribution valve 300, this embodiment enables the water purification component 100 to selectively supply purified water to multiple water-using devices, thereby significantly reducing the length of the entire water supply system and improving the maintainability of the water supply system.

[0132] In this embodiment, the liquid dispensing valve 300 and the water purification component 100 can be respectively installed in the cold storage compartment 700, so that users can regularly replace and maintain the liquid dispensing valve 300 and the water purification component 100.

[0133] like Figure 11 As shown, the water-using appliances in this embodiment include a first ice maker 400, a second ice maker 500, and a distributor 600. The first ice maker 400 is located in the refrigerator compartment 700, the second ice maker 500 is located in the freezer compartment 800 of the refrigeration equipment, and the distributor 600 is located on the door 900 of the refrigeration equipment.

[0134] Accordingly, the liquid dispensing valve 300 shown in this embodiment is a one-in-three-out valve. The outlet 12 of the water purification component 100 is connected to the inlet of the one-in-three-out valve. The first outlet of the one-in-three-out valve is connected to the first ice maker 400 located on the top of the cold storage room 700 through a pipeline. The second outlet of the one-in-three-out valve is connected to the second ice maker 500 through a pipeline. The third outlet of the one-in-three-out valve is connected to the distributor 600 through a pipeline.

[0135] During use, the purified water output by the water purification component 100 is controllably distributed to the first ice maker 400, the second ice maker 500 and the distributor 600 through a one-in-three-out valve to meet the ice-making needs of the first ice maker 400 or the second ice maker 500. Users can also take ice water through the distributor 600 without opening the door 900.

[0136] Furthermore, the refrigeration equipment shown in this embodiment can be a refrigerator or a freezer, and is not specifically limited here.

[0137] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
