Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, and in particular to a water control valve and a refrigerator. Background Technology

[0002] Water control valves are primarily automated control devices used to connect or disconnect fluid paths. Existing water control valves mainly consist of a valve body and a valve core. An electrical signal drives the valve core to move relative to the valve body, opening or closing the outlet on the valve body to achieve automatic control of the fluid path. The valve core is constantly in contact with the valve body for sealing, which causes sliding friction between the valve core and the valve body during operation. Over time, wear and tear due to this friction can lead to leaks and loss of sealing, affecting performance and lifespan. Utility Model Content

[0003] Therefore, it is necessary to provide a water control valve and refrigerator that can avoid wear caused by friction between the valve core and the valve body during valve core operation, thereby extending service life.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0005] A water control valve, the water control valve comprising:

[0006] The valve body has a valve cavity and a water outlet;

[0007] A valve core assembly includes a rotating shaft and a movable valve core. The rotating shaft is rotatably mounted in the valve cavity, and the movable valve core is fixed to the rotating shaft and can abut against the inner bottom wall of the valve body.

[0008] The electromagnetic assembly includes a first coil assembly and a second coil assembly, which are spaced apart along the axis of the rotating shaft. The first coil assembly is used to pull the moving valve core to move away from the outlet along the axis of the rotating shaft, so as to separate the moving valve core from the inner bottom wall of the valve body. The second coil assembly is used to drive the moving valve core to rotate, so as to open or close the outlet.

[0009] Understandably, this application, by setting up a first coil assembly and a second coil assembly, utilizes the first coil assembly to pull the moving valve core along the axis of rotation away from the outlet on the valve body, thereby separating the moving valve core from the inner bottom wall of the valve body. Then, the second coil assembly drives the moving valve core to rotate, opening or closing the outlet. In this way, during the automatic control of the fluid path, friction between the moving valve core and the inner bottom wall of the valve body, preventing damage, is avoided, thus extending the service life of the control valve. Furthermore, after the outlet opens or closes, the first coil assembly can be de-energized, allowing the moving valve core to contact and seal with the inner bottom wall of the valve body, ensuring the water control valve's sealing performance. In other words, by setting up a dual coil assembly, the moving valve core is separated from the valve body before rotation, avoiding contact and friction damage, thereby extending its service life.

[0010] In one embodiment, the first coil assembly includes a first coil and an iron core. The first coil is wound around the outer wall of the valve body, the iron core is located inside the valve cavity and passes through the rotating shaft, and the first coil is sleeved on the outside of the valve body along the circumferential direction of the rotating shaft.

[0011] When the first coil is energized, the iron core drives the rotating shaft to move the moving valve core away from the outlet along the axis of the rotating shaft, and the moving valve core separates from the inner bottom wall of the valve body.

[0012] It is understandable that by setting up the first coil and the iron core, the iron core is used to drive the rotating shaft to separate the moving valve core from the inner bottom wall, thereby avoiding frictional damage between the moving valve core and the valve body.

[0013] In one embodiment, the second coil assembly includes a second coil and a rotor. The second coil is wound around the outer wall of the valve body, the rotor is located inside the valve cavity and passes through the rotating shaft, and the second coil is sleeved on the outside of the rotor along the circumferential direction of the rotating shaft.

[0014] When the second coil is energized, the rotor causes the rotating shaft to drive the moving valve core to rotate, thereby opening or closing the water outlet.

[0015] It is understandable that by setting up the second coil and the rotor, the second coil acts on the rotor to make the rotating shaft drive the valve core to rotate in the circumferential direction of the rotating shaft, thereby controlling the water outlet and thus automatically controlling the fluid path.

[0016] In one embodiment, the valve chamber has a driving chamber and a main body chamber distributed vertically along the axial direction of the rotating shaft, the rotor and the iron core are located in the driving chamber, and the moving valve core is located in the main body chamber.

[0017] Understandably, distributing the drive chamber and the main body chamber vertically along the axis of rotation allows the electromagnetic assembly and the moving valve core to be inspected and maintained independently without the need for overall disassembly, thus improving the convenience of water control valve maintenance.

[0018] In one embodiment, the valve core assembly further includes an elastic element that is wound around the rotating shaft, with one end of the elastic element connected to the upper cavity wall of the main body cavity in the axial direction of the rotating shaft, and the other end connected to the moving valve core.

[0019] Understandably, the elastic element is designed so that after the moving valve core rotates to the corresponding position, it can drive the moving valve core to move along the axis of the rotating shaft towards the inner bottom wall of the valve body. This allows the moving valve core to reset and abut against the inner bottom wall of the valve body after the control outlet is opened or closed, thus achieving a seal on the water control valve.

[0020] In one embodiment, the valve core assembly further includes a sealing gasket fixed to the valve body, and the moving valve core abuts against the inner bottom wall of the valve body through the sealing gasket.

[0021] Understandably, the sealing gasket can improve the sealing effect between the valve body and the moving valve core, preventing water leakage from the control valve.

[0022] In one embodiment, the sealing gasket is configured as a cylinder with a through groove, the through groove being connected to the outlet and extending along the circumferential direction of the rotating shaft, the cross-sectional diameter of the through groove being D, the cross-sectional diameter of the moving valve core being D2, and the diameter of the outlet being D3, where D3 < D < D2.

[0023] Understandably, this design can improve the sealing effect of the water control valve while reducing the cost of installing the sealing gasket.

[0024] In one embodiment, the moving valve core is provided with a through hole, and along the axial direction of the rotating shaft, the water outlet is located on the inner bottom wall of the valve body, and the through hole is located above the water outlet;

[0025] The second coil assembly drives the valve core to rotate, aligning the through hole with the water outlet, thereby connecting the water outlet with the valve cavity and opening the water outlet.

[0026] In one embodiment, the valve body is provided with a positioning post, and the moving valve core is provided with a mating part. The mating part cooperates with the positioning post so that when the moving valve core rotates to the initial position, it controls the first coil assembly and the second coil assembly to be de-energized.

[0027] Understandably, the mating mechanism between the mating part and the positioning column ensures that the moving valve core stops precisely each time it rotates to the preset initial position, avoiding positioning errors caused by inertia or rotational deviation, improving the reset control effect. Furthermore, the mechanical structure enables power-off control, eliminating the need for additional sensors or electronic detection equipment, thus reducing the complexity and cost of the water control valve structure and control system. At the same time, it prevents the first and second coil assemblies from overheating due to prolonged energization, extending the service life of the water control valve.

[0028] This application also provides the following technical solutions:

[0029] A refrigerator includes the water control valve described in any of the above embodiments.

[0030] Compared to existing technologies, the aforementioned water control valve, by incorporating a first coil assembly and a second coil assembly, utilizes the first coil assembly to pull the moving valve core along the axis of rotation away from the outlet on the valve body. This separates the moving valve core from the inner bottom wall of the valve body. The second coil assembly then drives the moving valve core to rotate, opening or closing the outlet. This automatic control of the fluid path avoids friction damage between the moving valve core and the inner bottom wall of the valve body, thus extending the valve's service life. Furthermore, after the outlet opens or closes, the first coil assembly can be de-energized, ensuring a tight seal between the moving valve core and the inner bottom wall of the valve body, guaranteeing the valve's sealing performance. In short, the dual coil assembly ensures the moving valve core separates from the valve body before rotation, preventing friction damage and extending its service life. Attached Figure Description

[0044] Please see Figures 1 to 5 This application provides a water control valve 100, which includes a valve body 10, a valve core assembly 20, and an electromagnetic assembly 30. The valve body 10 has a valve cavity 11 and a water outlet 12. The valve core assembly 20 includes a rotating shaft 21 and a movable valve core 22. The rotating shaft 21 is rotatably installed in the valve cavity 11, and the movable valve core 22 is fixed to the rotating shaft 21 and can abut against the inner bottom wall 13 of the valve body 10. The electromagnetic assembly 30 includes a first coil assembly 31 and a second coil assembly 32. The first coil assembly 31 and the second coil assembly 32 are spaced apart along the axial direction of the rotating shaft 21. The first coil assembly 31 is used to pull the movable valve core 22 to move away from the water outlet 12 along the axial direction of the rotating shaft 21, so that the movable valve core 22 is separated from the inner bottom wall 13 of the valve body 10. The second coil assembly 32 is used to drive the movable valve core 22 to rotate, so as to open or close the water outlet 12.

[0045] It should be explained that in the existing water control valve 100, the valve core and valve body 10 are usually in contact and sealed. During the operation of the water control valve 100, the valve core moves directly relative to the valve body 10, which causes sliding friction between the valve core and the valve body 10. With this setting, after long-term use, both the valve core and the valve body 10 may experience wear due to mutual friction, resulting in a loose seal between them. The fluid will then leak directly from the outlet 12, affecting the performance and lifespan. This application, by setting up a first coil assembly 31 and a second coil assembly 32, uses the first coil assembly 31 to pull the moving valve core 22 along the axis of the rotating shaft 21 away from the outlet 12 on the valve body 10, thereby separating the moving valve core 22 from the inner bottom wall 13 of the valve body 10. Then, the second coil assembly 32 drives the moving valve core 22 to rotate, realizing the opening or closing of the outlet 12. In this way, during the automatic control of the fluid path, i.e. during the operation of the second coil assembly 32, friction between the moving valve core 22 and the inner bottom wall 13 of the valve body 10 is avoided, thus extending the service life of the water control valve 100. Moreover, after the outlet 12 is opened or closed, the first coil assembly 31 can be de-energized, so that the moving valve core 22 can make contact and seal with the inner bottom wall 13 of the valve body 10, ensuring the sealing performance of the water control valve 100. By using a dual-coil assembly, the moving valve core 22 is separated from the valve body 10 before rotation, avoiding contact between the two and causing friction damage, thereby extending the service life.

[0046] Here, the second coil assembly 32 controls the opening or closing of the water outlet at a relatively fast speed, and when the first coil assembly 31 is in action, the moving valve core 22 moves slightly away from the inner bottom wall 13 of the valve body 10 in the axial direction of the rotating shaft 21. Thus, the effect of the gap between the moving valve core 22 and the valve body 10 on the sealing effect between the moving valve core 22 and the valve body 10 can be ignored.

[0047] like Figure 3 As shown, along the axial direction of the rotating shaft 21, the valve chamber 11 has an upper and lower distributed drive chamber 111 and a main body chamber 112. The electromagnetic assembly 30 is located at the height of the drive chamber 111 on the valve body 10, and the moving valve core 22 is located in the main body chamber 112. In this way, by placing the electromagnetic assembly 30 and the moving valve core 22 in different areas of the valve body 10 along the axial direction of the rotating shaft 21, the electromagnetic assembly 30 and the moving valve core 22 can be independently inspected and maintained without the need for overall disassembly, thus reducing the maintenance cost of the water control valve 100 and improving the convenience of maintenance of the water control valve 100.

[0048] In this embodiment, to facilitate the explanation of the relationship between the components of the water control valve 100, the main cavity 112 is defined to have an upper cavity wall 1121, and the valve body 10 has an inner bottom wall 13 and an outer wall 14.

[0049] like Figure 3 and Figure 5 As shown, a positioning post 15 is provided on the valve body 10, and a mating part 222 is provided on the moving valve core 22. The mating part 222 cooperates with the positioning post 15 so that when the moving valve core 22 rotates to the initial position, it controls the first coil assembly 31 and the second coil assembly 32 to be de-energized. It can be understood that the cooperation between the mating part 222 and the positioning post 15 can ensure that the moving valve core 22 stops accurately each time it rotates to the preset initial position, avoiding positioning errors caused by inertia or rotational deviation, improving the reset control effect. Moreover, the power-off control is achieved through a mechanical structure, eliminating the need for additional sensors or electronic detection equipment, reducing the complexity and cost of the water control valve 100 structure and control system. At the same time, it avoids damage to the first coil assembly 31 and the second coil assembly 32 due to excessive temperature rise caused by prolonged energization, further extending the service life of the water control valve 100.

[0050] In this embodiment, the valve body 10 also has an inlet 16, through which fluid can enter the main body cavity 112 and then flow out from the outlet 12 through the moving valve core 22.

[0051] Please continue to refer to this. Figure 5 The moving valve core 22 is provided with a through hole 221, and along the axis of the rotating shaft 21, the outlet 12 is located on the inner bottom wall 13 of the valve body 10, with the through hole 221 located above the outlet 12; wherein, the second coil assembly 32 drives the moving valve core 22 to rotate, so that the through hole 221 is aligned with the outlet 12, so as to connect the outlet 12 with the valve cavity 11 and open the outlet 12.

[0052] Furthermore, multiple through holes 221 are provided, and the multiple through holes 221 are spaced apart in the axial direction around the rotating shaft 21, and the water outlet 12 is provided in a one-to-one correspondence with the through holes 221. In this way, the water control valve 100 can be used to control the connection or disconnection of multiple fluid paths.

[0053] Here, the through holes 221 can be set to two, three, or five. Of course, it is not limited to this; the specific number of through holes 221 can be set according to actual needs. In this embodiment, there are three through holes 221, and correspondingly three water outlets 12.

[0054] Furthermore, the valve core assembly 20 also includes an elastic element 23, which is wound around the rotating shaft 21. One end of the elastic element 23 is connected to the upper cavity wall 1121 of the main body cavity 112 along the axial direction of the rotating shaft 21, and the other end is connected to the moving valve core 22. Thus, after the moving valve core 22 rotates to the corresponding position, that is, after the first coil assembly 31 is de-energized, the elastic element 23 can drive the moving valve core 22 to move along the axial direction of the rotating shaft 21 towards the inner bottom wall 13 of the valve body 10 through its own elastic force. After the control outlet 12 is opened or closed, the moving valve core 22 can be reset and abut against the inner bottom wall 13 of the valve body 10, thereby achieving the sealing of the water control valve 100.

[0055] In one embodiment, the valve core assembly 20 further includes a sealing gasket 24, which is fixed to the valve body 10. The moving valve core 22 abuts against the inner bottom wall 13 of the valve body 10 through the sealing gasket 24. It is understood that the sealing gasket 24 can improve the sealing effect between the valve body 10 and the moving valve core 22, and prevent leakage of the water control valve 100.

[0056] Furthermore, the sealing gasket 24 is configured as a cylinder with a through groove 241, which communicates with the outlet 12. Along the circumferential direction of the rotating shaft 21, the cross-sectional diameter of the through groove 241 is D, the cross-sectional diameter of the moving valve core 22 is D2, and the diameter of the outlet 12 is D3, where D3 < D < D2. This improves the sealing effect of the water control valve 100 while reducing the installation cost of the sealing gasket 24.

[0057] Here, the number of sealing gaskets 24 is set one-to-one with the number of water outlets 12.

[0058] Please continue to refer to this. Figure 3 and Figure 5 The first coil assembly 31 includes a first coil 311 and an iron core 312. The first coil 311 is wound around the outer wall 14 of the valve body 10, and the iron core 312 is located inside the valve cavity 11 and passes through the rotating shaft 21. The first coil 311 is sleeved on the outer side of the valve body 10 along the circumferential direction of the rotating shaft 21. When the first coil 311 is energized, the iron core 312 drives the rotating shaft 21 to move the moving valve core 22 away from the outlet 12 along the axial direction of the rotating shaft 21, thus separating the moving valve core 22 from the inner bottom wall 13 of the valve body 10. In this way, the iron core 312 can be used to drive the rotating shaft to separate the moving valve core 22 from the inner bottom wall 13, thereby avoiding frictional damage between the moving valve core 22 and the valve body 10.

[0059] In one embodiment, the second coil assembly 32 includes a second coil 321 and a rotor 322. The second coil 321 is wound around the outer wall 14 of the valve body 10, and the rotor 322 is located inside the valve cavity 11 and passes through the rotating shaft 21. The second coil 321 is sleeved on the outside of the rotor 322 along the circumferential direction of the rotating shaft 21. When the second coil 321 is energized, the rotor 322 causes the rotating shaft 21 to drive the moving valve core 22 to rotate, thereby opening or closing the outlet 12. In this way, the action of the second coil 321 on the rotor 322 can be used to drive the rotating shaft 21 to rotate the moving valve core 22 in the circumferential direction of the rotating shaft 21, thereby controlling the outlet 12 and automating the fluid path control.

[0060] It should be noted that in this embodiment, both the rotor 322 and the iron core 312 are located inside the drive cavity 111.

[0061] This application also provides a refrigerator, including the water control valve 100 in any of the above embodiments. Thus, the water control valve 100 can be used in the fluid transport structure of ice-making or other structures inside the refrigerator.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
