Fig. 1 is a schematic structural diagram of a water valve 1 according to an embodiment of the present invention. Fig. 2 is a front view of fig. 1. Fig. 3 is a schematic structural view of the valve body 11 in fig. 1. Fig. 4 is a top view of fig. 3. Fig. 5 isbase:Sub>A sectional view taken along linebase:Sub>A-base:Sub>A in fig. 4.

Referring to fig. 1 to 5, a water valve 1 according to an embodiment of the present invention mainly includes a valve body 11, a valve plug assembly disposed in the valve body 11, and a flow meter 12 disposed at a water inlet end of the valve body 11.

Wherein, the valve body 11 is provided with a water inlet joint 13 and a water outlet joint 14 in a protruding way. The water inlet connector 13 is used as the water inlet end of the valve body 11 and is used for connecting a water source. The water outlet joint 14 is used as a water outlet end of the valve body 11 and is used for connecting a water using element so as to supply water for the water using element, such as an ice maker or a water dispenser of a refrigerator.

In some embodiments, the water outlet joint 14 includes a first water outlet joint 141 and a second water outlet joint 142. The first outlet joint 141 can be used for connecting a water using element, and the second outlet joint 142 can be used for connecting another water using element. Therefore, the water valve 1 of the present embodiment can supply water to two water using elements at the same time, or supply water to one of the water using elements separately.

It should be noted that in some embodiments, only one water outlet connector 14 may be provided, that is, the water outlet connector is used for supplying water to one water using element. In other embodiments, more than three water outlets 14 may be provided to supply water to three water using elements.

Referring to fig. 1 to 5, in some embodiments, a fixing seat 111 is disposed outside the valve body 11, and a fixing hole 112 is disposed on the fixing seat 111. The fixing seat 111 can be fixed by a screw inserted into the fixing hole 112, and the mounting position of the valve body 11 can be fixed, for example, inside a refrigerator.

Fig. 6 is a schematic structural view of the water cavity 15 and the water outlet passage 16 in fig. 5. Fig. 7 is a schematic view of the structure of fig. 6 from another perspective.

Referring to fig. 5 to 7, the interior of the valve body 11 is a hollow cavity structure, and a water cavity 15 and a water outlet channel 16 communicated with the water cavity 15 are disposed inside the valve body 11. Wherein, one end of the water cavity 15 is communicated with the water inlet connector 13, the water outlet channel 16 is positioned at the other end of the water cavity 15, and the water outlet channel 16 is used for connecting the water outlet connector 14. Thus, an external water source can enter the water cavity 15 through the water inlet connector 13 and then flow from the water outlet channel 16 to the water outlet connector 14, so as to supply water to the water using element.

In some embodiments, there are two outlet channels 16, namely a first outlet channel 161 and a second outlet channel 162. The first water outlet channel 161 and the second water outlet channel 162 are respectively communicated with the water cavity 15, and the first water outlet channel 161 and the second water outlet channel 162 are isolated from each other. One end of the first water outlet channel 161 far away from the water cavity 15 is communicated with the first water outlet joint 141, and one end of the second water outlet channel 162 far away from the water cavity 15 is communicated with the second water outlet joint 142. Therefore, the water in the water chamber 15 can flow to the first water outlet joint 141 through the first water outlet channel 161 or to the second water outlet joint 142 through the second water outlet channel 162, thereby respectively supplying water to different water using elements.

It should be noted that the number of the water outlet channels 16 is the same as the number of the water outlet joints 14, and the water outlet channels communicate with the water outlet joints in a one-to-one correspondence. Specifically, in other embodiments, when only one water outlet joint 14 is provided, only one water outlet channel 16 is provided; when a plurality of water outlet connectors 14 are provided, a plurality of water outlet channels 16 are also provided, and the plurality of water outlet channels 16 and the plurality of water outlet connectors 14 are arranged in one-to-one correspondence.

In some embodiments, the cross-sectional profile of the water chamber 15 is circular, and the cross-sectional profiles of the first outlet channel 161 and the second outlet channel 162 are also circular. It should be noted that, in other embodiments, the cross-sectional profiles of the water cavity 15, the first water outlet channel 161 and the second water outlet channel 162 may be formed in other manners, and are not limited herein.

Fig. 8 is an enlarged schematic view of a region B in fig. 5. Fig. 9 is a schematic structural view of the valve plug assembly of fig. 8. Fig. 10 is a front view of fig. 9. Fig. 11 is an exploded view of fig. 9. Fig. 12 is a cross-sectional view of fig. 9.

Referring to fig. 8 to 12, the valve plug assembly is disposed in the valve body 11 and disposed in the water outlet passage 16. The valve plug assembly is used for controlling the flow of the water outlet channel 16, and when the water pressure in the water inlet joint 13 and the water cavity 15 fluctuates within a certain range, the water flow flowing out of the water outlet joint 14 can be constant and kept within a certain deviation range.

In some embodiments, there are two sets of valve plug assemblies, and the two sets of valve plug assemblies are respectively disposed in the first outlet channel 161 and the second outlet channel 162.

It should be noted that the number of the valve plug assemblies is the same as the number of the water outlet passages 16, and the valve plug assemblies are arranged in a one-to-one correspondence. Specifically, when only one outlet passage 16 is provided, only one valve plug assembly is provided. When a plurality of water outlet channels 16 are provided, a plurality of valve plug assemblies are provided, and the plurality of valve plug assemblies and the plurality of water outlet channels 16 are arranged in a one-to-one correspondence manner.

Referring to fig. 8 to 12, the valve plug assembly includes a first valve plug 17 and a second valve plug 18. The first valve plug 17 and the second valve plug 18 may be configured in a circular shape, and the shape of the circular structure is matched with the shape of the water outlet channel 16.

The first valve plug 17 is disposed in the water outlet channel 16 and located at one end of the water outlet channel 16 close to the water cavity 15, and the first valve plug 17 is used for sealing the water outlet channel 16. Specifically, the periphery of the first valve plug 17 is hermetically connected to the peripheral wall of the water outlet channel 16, and the first valve plug 17 is provided with a water outlet hole 171 axially penetrating through the water outlet channel. Therefore, the periphery of the first valve plug 17 is in sealing contact with the peripheral sidewall of the outlet passage 16, so that water in the water chamber 15 can flow to only one end of the outlet passage 16 close to the outlet joint 14 through the outlet hole 171, and further flow to the corresponding outlet joint 14.

In some embodiments, the peripheral wall of the outlet passage 16 is recessed with a fitting groove 163 that fits with the peripheral wall of the first valve plug 17. The fitting groove 163 is shaped in an annular structure, and is adapted to the shape of the first valve plug 17, and the fitting groove 163 is disposed around the circumferential side of the first valve plug 17, so that the first valve plug 17 can be embedded in the fitting groove 163, and the first valve plug 17 is prevented from moving axially in the water outlet passage 16. And the outer periphery of the first valve plug 17 is sealingly coupled in the fitting groove 163, the water is effectively prevented from flowing through the gap between the outer peripheral wall of the first valve plug 17 and the inner wall of the fitting groove 163 to the end of the outlet passage 16 near the outlet joint 14.

In some embodiments, the width of the fitting groove 163 in the axial direction of the outlet passage 16 is slightly larger than the axial dimension of the first valve plug 17, thereby allowing a certain deformation space for the first valve plug 17, so that the first valve plug 17 can be always confined in the fitting groove 163.

Referring to fig. 8 to 12, in some embodiments, the outer peripheral wall of the first valve plug 17 is convexly provided with an annular rib 172, and the annular rib 172 is disposed around the outer peripheral wall of the first valve plug 17. When the first valve plug 17 is embedded in the assembling groove 163, the annular rib 172 can be clamped between the outer peripheral wall of the first valve plug 17 and the inner wall of the assembling groove 163, so that the sealing performance between the first valve plug 17 and the assembling groove 163 is improved, and the fastening performance of the first valve plug 17 in the assembling groove 163 is improved.

In some embodiments, there are two annular ribs 172, and the two annular ribs 172 are spaced apart from each other in the axial direction of the first valve plug 17. The two annular ribs 172 cooperate to further improve the sealing between the first valve plug 17 and the mounting groove 163 and to further improve the securement of the first valve plug 17 within the mounting groove 163.

It should be noted that, in some other embodiments, three or more annular ribs 172 may be provided, and the three or more annular ribs 172 are sequentially arranged at intervals along the axial direction of the first valve plug 17.

Referring to fig. 8 to 12, the second valve plug 18 is disposed in the water outlet channel 16, and the second valve plug 18 is disposed on the first valve plug 17 and is located on a side of the first valve plug 17 close to the water chamber 15. The center of the second valve plug 18 is connected to the first valve plug 17, a movable end 181 is formed on the periphery of the second valve plug 18, a first gap 182 is formed between the movable end 181 and the inner wall of the outlet passage 16, and a second gap 183 is formed between the movable end 181 and the first valve plug 17. The first gap 182 is communicated with the second gap 183, and the position of the water outlet hole 171 is opposite to the second gap 183, so that the second gap 183 can be communicated with the water outlet hole 171. Therefore, water in the water chamber 15 can enter the second gap 183 through the first gap 182, and then flow to the end of the water outlet channel 16 near the water outlet connector 14 through the water outlet hole 171. This expansion end 181 can produce certain deformation under hydraulic effect, and then is close to or keeps away from first valve plug 17, makes the clearance size of second clearance 183 change to a certain extent.

When the water pressure entering the water inlet joint 13 and the water cavity 15 fluctuates within a certain range, if the water pressure suddenly rises, the movable end 181 can be pressed to a side close to the first valve plug 17, but because a certain amount of water exists in the second gap 183, when the part of the water amount is extruded, the part of the water amount cannot completely pass through the water outlet 171 and enter the water outlet channel 16 at a moment, so that the part of the water amount can hinder and resist the deformation of the movable end 181, the size of the gap of the second gap 183 is kept unchanged, and the water flow flowing out from the water outlet joint 14 can be kept constant. When the water pressure is suddenly reduced, the movable end 181 can deform to the side away from the first valve plug 17, and the space of the second gap 183 is filled with a part of water, so that the volume of the second gap 183 cannot be instantly increased, and the deformation of the movable end 181 can be blocked and resisted, the gap size of the second gap 183 can be kept unchanged, and the water flow flowing out of the water outlet joint 14 can be kept constant, so that the water outlet amount is always kept within a certain deviation range.

In some embodiments, a connection column 173 is convexly formed on a side of the first valve plug 17 facing the second valve plug 18, and the second valve plug 18 is sleeved on the connection column 173. Meanwhile, the end of the connecting column 173 adjacent to the first valve plug 17 is formed with a boss 174. A boss 174 is integrally formed on the first valve plug 17, the boss 174 projects around the circumferential side of the connecting column 173, and the boss 174 is sandwiched between the second valve plug 18 and the first valve plug 17. Since the second valve plug 18 has a circular contour and the second valve plug 18 has a size larger than the boss 174, the portion of the second valve plug 18 protruding radially from the boss 174 forms a movable end 181, and a first gap 182 can be disposed around the peripheral wall of the second valve plug 18. Meanwhile, a second gap 183 can be formed between the second valve plug 18 and the first valve plug 17 on the periphery of the boss 174, so that the second gap 183 can be arranged around the boss 174, and the second gap 183 can be significantly larger than the water outlet hole 171, so that when the water pressure suddenly increases, water in the second gap 183 cannot instantly enter the water outlet hole 171, and when the water pressure suddenly decreases, water in the water outlet hole 171 cannot instantly flow back into the second gap 183, so that the size of the second gap 183 can be always kept within a tiny deviation range within a certain fluctuation range of the water pressure, and the amount of water flowing out from the water outlet channel 16 and the water outlet connector 14 can be kept constant.

It should also be noted that in other embodiments, the boss 174 may be replaced by a gasket or the like, i.e., the gasket is sleeved on the connecting column 173 so as to be clamped between the second valve plug 18 and the first valve plug 17. It is also possible to form the movable end 181 with the portion of the second valve plug 18 radially beyond the gasket, while the peripheral side of the gasket can form a second gap 183 between the second valve plug 18 and the first valve plug 17.

It should be noted that the width of the first gap 182, the width of the second gap 183, and the aperture of the outlet hole 171 on the first valve plug 17 can be adjusted according to the requirement of the outlet volume of the outlet joint 14, so that the water volume flowing out of the outlet passage 16 and the outlet joint 14 can be kept within a specific range. Therefore, the width of the first gap 182, the width of the second gap 183, and the aperture of the water outlet hole 171 on the first valve plug 17 are not limited in particular.

In some embodiments, a plurality of outlet holes 171 may be disposed on the first valve body 11, and the plurality of outlet holes 171 are disposed on the first valve body 11 at intervals and are all communicated with the second gap 183. The water quantity flowing out of the water outlet channel 16 and the water outlet joint 14 can be increased by the plurality of water outlet holes 171, and the number of the water outlet holes 171 can be adjusted according to requirements.

Referring to fig. 11 and 12, in some embodiments, the second valve plug 18 has a shaft hole 184 formed in the center thereof, the shaft hole 184 axially penetrates through the second valve plug 18, and the second valve plug 18 is detachably sleeved on the connecting column 173 through the shaft hole 184. The shaft hole 184 can be in interference fit with the connecting column 173, so that the second valve plug 18 can be relatively stably sleeved on the connecting column 173.

It should be noted that, in other embodiments, the second valve plug 18 may be integrally formed on the connecting column 173, that is, the first valve plug 17 and the second valve plug 18 are integrally formed.

Referring to fig. 11 and 12, in some embodiments, a limit portion 185 is protruded on the peripheral side of the second valve plug 18. The peripheral side wall of the water outlet channel 16 is concavely provided with a limit groove 164 matched with the limit part 185. The shape of the limiting groove 164 is matched with the limiting portion 185, and the limiting groove 164 is used for limiting the limiting portion 185 in the circumferential direction, so that the second valve plug 18 is prevented from rotating around the connecting column 173. Meanwhile, a part of the first gap 182 is formed between the stopper groove 164 and the stopper portion 185, so that water in the water chamber 15 can flow through the gap between the stopper groove 164 and the stopper portion 185 and flow into the second gap 183.

Referring to fig. 8 to 12, in some embodiments, an end of the connecting column 173 near the water chamber 15 protrudes from the second valve plug 18 and extends into the water chamber 15 to prevent the second valve plug 18 from being separated from the second valve plug 18.

In some embodiments, the end of the connecting column 173 extending into the water chamber 15 is convexly provided with the protrusion 175, and the diameter of the protrusion 175 is smaller than the diameter of the connecting column 173, so that the diameter of the protrusion 175 is smaller, the occupation of the space in the water chamber 15 can be reduced, the resistance to the water flow in the water chamber 15 is reduced, and the water in the water chamber 15 can smoothly flow through the connecting column 173 into the first gap 182 and the second gap 183.

Referring to fig. 1 and 2, a flow meter 12 is disposed at a water inlet end of the valve body 11, the flow meter 12 is connected to a water inlet connector 13 through a water inlet pipe, and the flow meter 12 is used for connecting a water source. The water supply is thus able to flow into the water chamber 15 in the valve body 11 through the water inlet connector 13 under the control of the flow meter 12. Under external water source is in different water pressure states, flowmeter 12 can detect the water yield of inflow to ensure that the water yield that gets into in the water cavity 15 accords with the setting value, the water pressure that gets into in the water cavity 15 keeps in certain stirring within range, and then can cooperate the valve plug subassembly to keep out water passageway 16 and the water volume that goes out water joint 14 and flow invariable.

Fig. 13 is a schematic structural view of a refrigerator according to an embodiment of the present invention.
