Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a water purification component and a refrigeration device. Background Art

[0002] In the related art, when the filter of the water purification component is installed on the seat, the filter is connected to the water path in the seat, thereby realizing the filtration of the liquid; when the filter is removed, the water inlet and outlet of the seat are disconnected, so that the water path of the seat cannot be connected. If the water path of the seat is to be connected, a matching plug is required, which makes the switching of the water path of the seat time-consuming and laborious. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a water purification component.

[0005] A second aspect of the present invention further provides a refrigeration device.

[0006] In view of this, the first aspect of the present invention proposes a water purification component, comprising: a seat body, provided with a first water inlet and a first water outlet; a switching member, arranged in the seat body and rotatably connected to the seat body, the switching member being provided with a first channel; a filter, detachably connected to the seat body so that the filter has an assembled state and a disassembled state, and during the process of switching the filter between the assembled state and the disassembled state, the filter can cooperate with the switching member to drive the switching member to rotate between a first position and a second position; when the filter is in the assembled state, the switching member is located in the second position, one end of the first channel is connected to the first water inlet, the other end of the first channel is connected to the first water outlet, and the first channel is connected to the filter; when the filter is in the disassembled state, the switching member is located in the first position, the two ends of the first channel are staggered with the first water inlet and the first water outlet, the surface of the switching member and the inner wall surface of the seat body enclose a second channel, and the first water inlet is connected to the first water outlet through the second channel.

[0007] The water purification component provided by the present invention includes a seat body, a switching member and a filter. The seat body is provided with a first water inlet and a first water outlet, the switching member is provided with a first channel, the switching member is arranged in the seat body and is rotatably connected to the seat body, the filter can be detachably connected to the seat body, and during the process of disassembly and assembly of the filter relative to the seat body, the filter can drive the switching member to rotate between a first position and a second position to realize the switching of the path connected between the first water inlet and the first water outlet. In which, during the process of assembling the filter, the filter drives the switching member to rotate to the second position. When the switching member is in the second position, one end of the first channel is connected to the first water inlet, the first water outlet is connected to the other end of the first channel, and the filter is connected to the first channel, so that the liquid flowing into the seat body from the first water inlet flows into the filter through one end of the first channel, and then flows to the first water outlet from the other end of the first channel after being filtered by the filter, and finally flows out of the seat body, thereby achieving liquid filtration and improving water quality; in the process of disassembling the filter, the filter moves relative to the seat body, thereby being able to drive the switching member to switch to the first position. When the switching member is in the first position, the first channel on the switching member cannot connect the first water inlet and the first water outlet, so that the liquid flowing into the first water inlet cannot flow into the first channel, thereby avoiding leakage when the filter is pulled out, and when the switching member is in the first position, the outer surface of the switching member and the inner wall surface of the seat body enclose the second channel, and the first water inlet is connected to the first water outlet through the second channel, so that when the filter is pulled out, the liquid can still be transported, thereby ensuring the reliability of liquid transportation. The water purification component proposed in the present application can be linked to the switching member when the filter is assembled and disassembled, so that the movement of the switching member does not need to be driven by other driving structures, thereby reducing the number of parts and components and reducing the overall volume of the water purification component. When the filter is removed, the first water inlet and the first water outlet are connected through the outer surface of the switching member, and there is no need to set a through channel on the switching member to achieve the connection between the first water inlet and the first water outlet, which simplifies the manufacturing difficulty of the switching member, facilitates the mold forming of the switching member, and reduces the manufacturing cost. Moreover, the switching of the connecting channel can be achieved by rotating the switching member around its own rotation axis, and there is no need to set up an additional movement space for the switching member, thereby improving the space utilization inside the seat body.

[0008] It is understandable that the filter proposed in the present application is detachably connected to the seat body, so that the filter can be replaced or repaired to ensure the reliability of water purification by the water purification component.

[0009] Optionally, during the process of assembling the filter, the filter switches from a disassembled state to an assembled state, and at the same time the filter can drive the switching member to rotate, so that the switching member switches from a first position to a second position; during the process of disassembling the filter, the filter switches from an assembled state to a disassembled state, and at the same time the filter can drive the switching member to rotate, so that the switching member switches from the second position to the first position.

[0010] Optionally, the filter is rotationally engaged with the seat.

[0011] Optionally, the filter is connected between the two ends of the first channel, so that the liquid can flow into the first channel from the first water inlet, then flow to the filter through the first channel, and then flow to the first water outlet through the other end of the first channel.

[0014] In this embodiment, the surface of the switching member is provided with a first sink and at least two second sinks, the at least two second sinks are arranged at intervals along the circumferential direction of the switching member, and the first sink is arranged at one end of the at least two second sinks along the axial direction, thereby realizing the connection of the at least two second sinks. When the switching member is located in the first position, the first sink, the at least two second sinks and the inner surface of the seat body enclose a second channel, and the at least two second sinks are arranged opposite to the first water inlet and the first water outlet, respectively, so that the at least two second sinks can be connected to the first water inlet and the first water outlet, respectively, so that the liquid flowing into the first water inlet can flow into the second channel through the second sink corresponding to the first water inlet, and then flow to the second sink corresponding to the first water outlet through the connection of the first sink, and then flow out of the seat body through the first water outlet, so as to realize the liquid transportation when the filter is removed. The water purification component proposed in the present application is provided with a first sink groove and a second sink groove on the surface of the switching component, thereby realizing the connection between the first water inlet and the first water outlet, so that when the filter is disassembled, the liquid does not pass through any space inside the switching component. For the switching component, the processing difficulty of the switching component is reduced, the manufacturing cost of the switching component is reduced, and the overall cost of the water purification component is reduced.

[0015] In some embodiments, optionally, the first sink groove is arranged in a ring shape along the circumference of the switching member.

[0016] In this embodiment, the first sink is annular along the circumference of the switching member, so that water can flow through the first sink along the circumference of the switching member, thereby increasing the liquid flow rate and liquid flow when the switching member is in the first position.

[0017] In some embodiments, optionally, at least two second sinks are provided on opposite sides of the switching member.

[0018] In this embodiment, at least two second sinks are arranged on two opposite sides of the switching member, so that the second sinks are symmetrically arranged, which facilitates the processing of the switching member.

[0020] In this embodiment, the water purification component also includes a first sealing ring, which is arranged on the outer wall of the switching member, and the first trough is arranged at an end of the second trough away from the filter. The first sealing ring is located at an end of the second trough away from the first trough, and a sealed connection is formed between the first sealing ring and the seat body, thereby preventing the liquid flowing into the seat body through the first water inlet from flowing out of the seat body through the gap between the switching member and the seat body, thereby ensuring the sealing of the water flow path.

[0021] In some embodiments, optionally, the water purification component also includes: at least two second sealing rings, respectively arranged at the two ends of the first channel; when the switching member is in the first position, the second sealing ring contacts the inner wall surface of the seat body to seal the first channel; when the switching member is in the second position, one end of the first channel is connected to the first water inlet through the second sealing ring, and the other end of the first channel is connected to the first water outlet through the second sealing ring.

[0022] In this embodiment, the water purification component also includes at least two second sealing rings, and at least two second sealing rings are respectively arranged at the two ends of the first channel. When the switching member is located in the first position, one end of the first channel is staggered with the first water inlet, and the other end of the first channel is staggered with the first water outlet. The second sealing ring contacts the inner wall surface of the seat body, so that the gap between the two ends of the first channel and the seat body is sealed, and the liquid is prevented from flowing into the first channel through the gap between the two and causing leakage. When the switching member is located in the second position, one end of the first channel is connected to the first water inlet through the second sealing ring, and the sealing of the connection between the first channel and the first water inlet is realized through the second sealing ring, so as to avoid leakage at the connection between one end of the first channel and the first water inlet; the other end of the first channel is connected to the first water outlet through the second sealing ring, and the sealing of the connection between the other end of the first channel and the first water outlet is realized through the second sealing ring, so as to avoid leakage at the connection between the other end of the first channel and the first water outlet.

[0024] In this embodiment, the filter includes a bottle body, a filter element and a water stop. The filter element is arranged in the bottle body for filtering liquid. The water stop is arranged in the bottle body and located at one end of the filter element. The water stop and the inner wall surface of the opening enclose a water stop gap. At the same time, a third channel is arranged on the water stop. The first channel includes a water inlet channel and a water outlet channel. When the filter is in an assembled state, the two ends of the water inlet channel are respectively connected to the first water inlet and the water stop gap, and the two ends of the water outlet channel are respectively connected to the third channel and the first water outlet, so that the liquid flowing into the water inlet channel from the first water inlet enters the bottle body through the water stop gap, and after being filtered by the filter element, flows from the third channel to the water outlet channel, and then flows from the water outlet channel to the first water outlet, thereby achieving liquid purification. When the filter is in a disassembled state, the water in the water stop gap forms a water film due to the effect of surface tension, thereby preventing air from entering the bottle body, so that the liquid in the bottle body will not flow out, and the amount of dripping when the filter is replaced is reduced. That is, by setting the water-stop gap, the filter can be connected to the water inlet channel in the assembled state, and can automatically stop water through the formation of a water film in the disassembled state to avoid water leakage.

The filter 3 can be detachably connected to the seat body 1, and during the process of disassembling and assembling the filter 3 relative to the seat body 1, the filter 3 can drive the switching member 2 to rotate between the first position and the second position to realize the switching of the path connected between the first water inlet 10 and the first water outlet 12. In the process of assembling the filter 3, the filter 3 drives the switching member 2 to rotate to the second position, such as Figure 2 and Figure 5 As shown, when the switching member 2 is in the second position, one end of the first channel 20 is connected to the first water inlet 10, the first water outlet 12 is connected to the other end of the first channel 20, and the filter 3 is connected to the first channel 20, so that the liquid flowing into the seat body 1 from the first water inlet 10 flows into the filter 3 through one end of the first channel 20, and then flows to the first water outlet 12 from the other end of the first channel 20 after being filtered by the filter 3, and finally flows out of the seat body 1 (the direction of water flow is shown in FIG. Figure 5 In the process of removing the filter 3, the filter 3 moves relative to the seat body 1, thereby driving the switching member 2 to switch to the first position, such as Figure 7As shown, when the switching member 2 is in the first position, the first channel 20 on the switching member 2 cannot communicate with the first water inlet 10 and the first water outlet 12, so that the liquid flowing into the first water inlet 10 cannot flow into the first channel 20, thereby avoiding leakage when the filter 3 is unplugged. In addition, when the switching member 2 is in the first position, the outer surface of the switching member 2 and the inner wall surface of the seat body 1 enclose a second channel 14, and the first water inlet 10 is connected with the first water outlet 12 through the second channel 14, so that when the filter 3 is unplugged, the liquid can still be transported (the flow direction of the liquid is as shown in FIG. Figure 7 ), ensuring the reliability of liquid transportation. The water purification component proposed in the present application can be linked to the switching member 2 in the disassembly and assembly of the filter 3, so that the movement of the switching member 2 does not require the drive of other driving structures, reducing the number of parts and components, reducing the overall volume of the water purification component, and when the filter 3 is disassembled, the first water inlet 10 and the first water outlet 12 are connected through the outer surface of the switching member 2, and there is no need to set a through channel on the switching member 2 to achieve the connection between the first water inlet 10 and the first water outlet 12, which simplifies the manufacturing difficulty of the switching member 2, makes the mold forming of the switching member 2 convenient, reduces the manufacturing cost, and the switching of the connecting channel can be achieved by rotating the switching member 2 around its own rotation axis, without the need to set up an additional movement space for the switching member 2, so that the space utilization rate inside the seat body 1 is improved.

[0088] It is understandable that the filter 3 proposed in the present application is detachably connected to the seat body 1, so that the filter 3 can be replaced or repaired to ensure the reliability of the water purification component in water purification.

[0093] In this embodiment, a first groove 21 and at least two second grooves 22 are provided on the surface of the switching member 2. The at least two second grooves 22 are arranged at intervals along the circumferential direction of rotation of the switching member 2.

In this way, the liquid flowing into the first water inlet 10 can flow into the second channel 14 through the second sink 22 corresponding to the first water inlet 10, and then flow to the second sink 22 corresponding to the first water outlet 12 through the connection with the first sink 21, and then flow out of the seat body 1 through the first water outlet 12, so as to realize the liquid transportation when the filter 3 is removed. The water purification component proposed in the present application is provided with a first trough 21 and a second trough 22 on the surface of the switching member 2, so as to realize the connection between the first water inlet 10 and the first water outlet 12, so that when the filter 3 is disassembled, the liquid does not pass through any space inside the switching member 2. For the switching member 2, the processing difficulty of the switching member 2 is reduced, so that the manufacturing cost of the switching member 2 is reduced, thereby reducing the overall cost of the water purification component.

[0102] In this embodiment, the water purification component further includes at least two second sealing rings 5, which are respectively arranged at the two ends of the first channel 20. When the switching member 2 is located at the first position, one end of the first channel 20 is staggered with the first water inlet 10, and the other end of the first channel 20 is staggered with the first water outlet 12, and the second sealing ring 5 contacts the inner wall surface of the seat body 1, so that the gap between the two ends of the first channel 20 and the seat body 1 is sealed, so as to prevent liquid from flowing into the first channel 20 through the gap between the two and causing leakage. When the switching member 2 is in the second position, one end of the first channel 20 is connected to the first water inlet 10 via the second sealing ring 5, and the sealing of the connection between the first channel 20 and the first water inlet 10 is achieved by the second sealing ring 5, thereby avoiding leakage at the connection between one end of the first channel 20 and the first water inlet 10; the other end of the first channel 20 is connected to the first water outlet 12 via the second sealing ring 5, and the sealing of the connection between the other end of the first channel 20 and the first water outlet 12 is achieved by the second sealing ring 5, thereby avoiding leakage at the connection between the other end of the first channel 20 and the first water outlet 12.

That is, through the setting of the water stop gap 33, the filter 3 can be connected with the water inlet channel 202 in the assembled state, and can automatically stop water through the formation of a water film in the disassembled state to avoid water leakage.

[0106] Optionally, the water-stop gap 33 is larger than 0 mm and smaller than or equal to 1 mm, so as to ensure that water can form a water film in the water-stop gap 33 due to the effect of tension, thereby avoiding water-stop failure.

[0139] like Figures 11 to 16 As shown, the socket is composed of a socket body (e.g., a socket body 1), a rotating center rod (e.g., a switching member 2), a welded fixing ring (e.g., a fixing ring 6), a water inlet joint (provided with a first water inlet 10), a water outlet joint (provided with a first water outlet 12), and a plurality of sealing rings, and the assembly is completed by an ultrasonic welding process. The water purification module is composed of an upper end cover (e.g., a water stop 32), a filter material (e.g., a filter element 31), a lower end cover, a filter bottle (e.g., a bottle body 30), and a tail. Optionally, the water purification module also includes a handle 37, and the filter bottle and the tail are completed by rotation welding.

[0140] The water inlet and outlet joints of the socket are connected to the water inlet pipe and the water outlet pipe respectively. When the socket is not installed with the filter 3, Figure 7 As shown, at this time, the water inlet and outlet of the rotating center rod (such as the second water inlet 2020 and the third water outlet 2042) are staggered with the water inlet and outlet of the socket body (such as the water inlet joint and the water outlet joint) by an angle (optionally, this angle is 90°), and the sealing ring (such as the second sealing ring 5) makes the water inlet and outlet of the rotating center rod and the inner wall of the socket body form a seal, and water cannot flow into the rotating center rod. At this time, the water flowing into the socket from the water inlet joint flows into the water outlet joint through the structural steps and gaps between the rotating center rod and the socket body (such as the first sink 21 and the second sink 22), forming a water flow path.

[0141] like Fig. 22 As shown, when the water purification module is assembled with the socket, the long arm at the bottom of the rotating center rod (e.g., the first limit portion 29) extends into the corresponding notch structure of the upper end cover (e.g., the second limit portion 36). When the water purification module is rotated and fastened with the socket, because the upper end cover is fixedly connected to the water purification module, the water purification module will drive the rotating center rod inside the socket to rotate a certain angle, so that the water inlet and outlet of the rotating center rod are connected to the water inlet and outlet of the socket. Among them, the rotation angle of the rotating center rod can be adjusted by adjusting the width of the notch structure and the width of the long arm at the bottom of the rotating center rod, so as to realize a design in which the rotation angle of the rotating center rod is the same or different from that of the water purification module.

[0142] When the water purification module reaches the end of its service life or is disassembled midway, the notch structure of the upper end cover drives the long arm at the bottom of the rotating center rod to rotate in the opposite direction by the same angle, thereby restoring the rotating center rod to the position where the bypass channel is formed.

[0143] Optionally, regarding the implementation method of the rotation of the rotating center rod, the long arm at the bottom of the rotating center rod may extend into a specific structure at the mouth of the filter bottle, and the limit fit between the two allows the filter 3 to drive the rotating center rod to rotate during disassembly and assembly.

[0144] Alternatively, if Figure 6 As shown, the upper end cover is assembled with the filter bottle, and the assembly gap between the upper end cover and the filter bottle (such as the water-stop gap 33) is controlled within 1 mm, so that when the water purification module is removed, water forms a water film in the narrow gap due to the surface tension of the water.

[0145] Optionally, in order to avoid the problem of water-stop failure caused by the local size of the water-stop gap 33 being too large due to local shrinkage in the injection molding process, the upper end cover may be reinforced.

[0146] Alternatively, if Fig.29 As shown, in addition to controlling the assembly gap between the upper end cap and the filter bottle to be within 1 mm, a slit (such as slit 38) with a gap within 1 mm can also be designed on the upper end cap to increase the water flow area and prevent clogging in actual use.

[0147] Optionally, in order to adapt to the two scenarios of refrigerator compartment and horizontal installation, a detachable handle 37 is designed at the tail of the filter 3. When the filter 3 is installed on the top or door of the refrigerator compartment, the filter 3 and the socket are rotated and installed. At this time, the tail of the bottle body of the filter 3 can be grasped without the need to use the handle 37. When the filter 3 is installed horizontally, the user has no other contact position. In this scenario, the filter 3 is equipped with a handle 37, and disassembly and assembly are achieved by grasping the handle 37. Optionally, the installation of the handle 37 and the tail of the filter 3 can be achieved by snapping, socketing or welding, which can achieve lean manufacturing and realize differentiated usage scenarios with minimal material changes.

[0148] The water purification component proposed in the present application drives the rotating center rod to rotate during the installation process of the water purification module, thereby realizing the switching of the bypass channel (for example, the channel formed by the first water inlet 10, the second channel 14 and the first water outlet 12) to the purification channel (for example, the channel formed by the first water inlet 10, the first channel 20, the filter 3 and the first water outlet 12), without the need for additional operations, saving time and effort.

[0149] Optionally, the long arm is on the rotating central rod, and the notch structure is arranged on the water purification module, and the positions can also be reversed. At the same time, the number of sleeve positions between the rotating central rod and the water purification module should be no less than one.

[0150] Optionally, the notch structure may also be a groove or the like.
