Description

Technical Field

[0001] This utility model belongs to the field of washing machine valve technology, specifically relating to a multi-functional integrated water inlet valve. Background Technology

[0002] With the development of smart home appliances, washing machines are becoming increasingly feature-rich. To meet these diverse needs, the inlet valve, a crucial component of the washing machine, is constantly being updated, featuring multiple outlets on the valve body, each with a different flow rate. As washing machines are continuously updated, the number of inlet valve outlets also increases. A patent document with publication number CN214793341U discloses a turbine flow meter valve, comprising a valve body with a medium flow channel, an inlet end connected to the medium flow channel, an outlet end connected to the medium flow channel, a flow component mounted on the valve body, and a signal receiver mounted on the valve body. The flow component includes a rotating impeller integrally made of magnetic material and a fixed impeller that cooperates with the rotating impeller. The currently disclosed valve body connects the outlets to the washing machine via independent pipes, requiring an additional outlet for each additional flow rate requirement. This not only poses a challenge to operators in correctly installing the corresponding interfaces during pipework but also increases installation material costs. Meanwhile, each additional flow rate requirement necessitates the addition of new connecting pipes; the increased number of pipes reduces the overall assembly efficiency and increases the risk of incorrect pipe installation and pipe interface leakage; therefore, a multi-functional integrated inlet valve needs to be designed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a multi-functional integrated water inlet valve. By setting a water outlet cover for conversion on the main valve body, the number of water outlets is reduced, making installation more convenient and manufacturing costs lower.

[0004] The objective of this invention is achieved through the following technical solution: a multi-functional integrated water inlet valve, comprising a main valve body with a water inlet, and a high-flow seat assembly disposed near the water inlet within the main valve body; the main valve body also comprises several parallel and mutually separated high-flow channels and low-flow channels, and the open end of the main valve body is provided with several flow electrical control components for controlling the conduction state of the water inlet and the high-flow channels, and the open end of the main valve body is also provided with flow electrical control components for controlling the conduction state of the water inlet and the low-flow channels; a low-flow seat assembly is disposed on the outlet water of the low-flow channel, wherein an outlet cover is disposed between two adjacent high-flow channels and low-flow channels, and the outlet cover is sealed to the main valve body.

[0005] Preferably, each of the flow control components includes a plastic seal, a coil assembly, an iron core assembly, and a rubber core; the plastic seal is installed on the open end of the main valve body, and the coil assembly and the iron core assembly are disposed inside the plastic seal, with the iron core assembly slidably installed inside the plastic seal; the end of the iron core assembly is provided with a rubber core, and when the coil assembly is energized, it drives the iron core assembly to move relative to the open end of the main valve body.

[0006] Preferably, the main valve body has a plurality of sealing ring frame assemblies at its open end, each sealing ring frame assembly corresponding to each flow control component, and the rubber core is arranged adjacent to the sealing ring frame assembly; the sealing ring frame assembly is arranged between the water inlet and the high flow channel, or the sealing ring frame assembly is arranged between the water inlet and the low flow channel.

[0007] The low-flow and high-flow channels share a single inlet. Each low-flow and high-flow channel is independent, and their on / off states can be controlled separately via a flow control component. By default, the rubber core rests against the hole in the sealing ring assembly, thus both the low-flow and high-flow channels are disconnected, and the main valve body is closed. When the washing machine requires a specific flow rate, simply activate the corresponding channel's flow control component via the control panel. When the coil assembly for the corresponding channel is energized, the iron core assembly retracts, moving the rubber core away from the sealing ring assembly, thus opening the corresponding low-flow or high-flow channel.

[0008] Preferably, the high-flow-rate seat assembly includes a high-flow-rate seat body and a large pressure-reducing ring, with the large pressure-reducing ring sleeved and installed on the high-flow-rate seat body; the high-flow-rate seat body is installed in the main valve body; the high-flow-rate seat assembly is arranged adjacent to the initial end of the high-flow-rate channel and also adjacent to the initial end of the low-flow-rate channel.

[0009] Preferably, the main valve body is also provided with a filter assembly, which is located near the water inlet; the high-flow seat body is installed between the filter assembly and the step in the main valve body.

[0010] By setting up a high-flow-rate seat component, the water flow can be automatically adjusted as the water flows through the high-flow-rate seat body. Then, the corresponding high-flow-rate channel opens and the low-flow-rate channel closes, resulting in a larger water flow coming out of the water outlet cover.

[0011] Preferably, the low-flow-rate seat assembly includes a low-flow-rate seat body and a small pressure-reducing ring; the small pressure-reducing ring is sleeved and installed on the low-flow-rate seat body, and the low-flow-rate seat body is installed at the end of the low-flow-rate channel; an annular protrusion is provided on the outer wall of the low-flow-rate seat body, and an annular groove is provided in the low-flow-rate channel; the annular protrusion and the annular groove are mutually adapted to each other, and when the low-flow-rate seat body is installed in the low-flow-rate channel, the annular protrusion is set in the annular groove.

[0012] Because the small flow seat assembly is located at the end of the small flow channel, the water flow undergoes initial flow regulation after passing through the large flow seat assembly. When the water is about to exit through the outlet cover, the flow is regulated again by the small flow seat assembly. At this point, the corresponding large flow channel closes and the small flow channel opens, resulting in a smaller water flow exiting the outlet cover. The annular groove and annular protrusion facilitate stable installation of the small flow seat body.

[0013] Preferably, the water outlet cover is provided with a common water outlet; the common water outlet is interconnected with the high flow channel, and the common water outlet is interconnected with the low flow channel.

[0014] Preferably, the outlet cover is welded to the main valve body, forming a single unit. The main valve body contains a welding groove, and the protrusion on the outlet cover is positioned within this groove. Welding the outlet cover to the main valve body ensures a tighter connection, better sealing, and easier processing.

[0015] Preferably, the outlet cover is detachably connected to the main valve body, and a sealing element is provided between the outlet cover and the main valve body to seal both. This facilitates the replacement of the outlet cover and makes disassembly and assembly convenient. The outer contour of the sealing element is adapted to the outer contour of the main valve body, and the outer contour of the sealing element is also adapted to the outer contour of the outlet cover; the sealing element is not shown in the drawings in the instruction manual.

[0016] Compared with existing technologies, this utility model has the following advantages: 1. Since the large flow channel and the small flow channel share a single outlet cover for water discharge, it facilitates the connection of the main valve body to the washing machine; it also reduces the number of intermediate connecting pipes to the washing machine, resulting in lower manufacturing costs; 2. By using a single outlet cover for common water discharge, the connection between the main valve body and the washing machine is simpler, and the assembly efficiency is higher; 3. The number of water outlets on the main valve body is reduced, decreasing the number of pipe connections and thus reducing the probability of incorrect pipe connections; 4. The large flow channel and the small flow channel are independent of each other, making flow control more convenient and improving versatility. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figures 1 to 4 As shown, this embodiment discloses a multifunctional integrated water inlet valve, including a main valve body 1, a water inlet 2 on the main valve body 1, and a large flow seat assembly 3 disposed near the water inlet 2 inside the main valve body 1; the main valve body 1 also has several large flow channels 4 and small flow channels 5 arranged side by side and separated from each other, and several flow electrical control components 6 for controlling the conduction state of the water inlet 2 and the large flow channels 4 are provided at the open end of the main valve body 1, and the flow electrical control components 6 for controlling the conduction state of the water inlet 2 and the small flow channels 5 are also provided at the open end of the main valve body 1; a small flow seat assembly 7 is provided on the outlet water of the small flow channel 5, and an outlet cover 8 is provided between two adjacent large flow channels 4 and small flow channels 5, and the outlet cover 8 is sealed to the main valve body 1.

[0024] Each of the flow control components 6 includes a plastic seal 61, a coil assembly 62, an iron core assembly 63, and a rubber core 64. The plastic seal 61 is installed on the open end of the main valve body 1. The coil assembly 62 and the iron core assembly 63 are housed inside the plastic seal 61, and the iron core assembly 63 is slidably installed inside the plastic seal 61. The end of the iron core assembly 63 is provided with a rubber core 64. When the coil assembly 62 is energized, it drives the iron core assembly 63 to move relative to the open end of the main valve body 1. The open end of the main valve body 1 is provided with a plurality of sealing ring frame assemblies 9. Each sealing ring frame assembly 9 corresponds one-to-one with each of the flow control components 6. The rubber core 64 is arranged adjacent to the sealing ring frame assembly 9. The sealing ring frame assembly 9 is arranged between the inlet 2 and the large flow channel 4, or between the inlet 2 and the small flow channel 5.

[0025] The high-flow-rate seat assembly 3 includes a high-flow-rate seat body 31 and a large pressure-reducing ring 32, the large pressure-reducing ring 32 being sleeved and installed on the high-flow-rate seat body 31; the high-flow-rate seat body 31 is installed inside the main valve body 1, the high-flow-rate seat assembly 3 is adjacent to the initial end of the high-flow-rate channel 4, and the high-flow-rate seat assembly 3 is also adjacent to the initial end of the low-flow-rate channel 5. A filter assembly 10 is also provided inside the main valve body 1, the filter assembly 10 being positioned near the inlet 2; the high-flow-rate seat body 31 is installed between the filter assembly 10 and the step inside the main valve body 1. The small flow seat assembly 7 includes a small flow seat body 71 and a small pressure relief ring 72; the small pressure relief ring 72 is sleeved and installed on the small flow seat body 71, and the small flow seat body 71 is installed at the end of the small flow channel 5; an annular protrusion 73 is provided on the outer wall of the small flow seat body 71, and an annular groove 11 is provided in the small flow channel 5; the annular protrusion 73 and the annular groove are adapted to each other, and when the small flow seat body 71 is installed in the small flow channel 5, the annular protrusion 73 is set in the annular groove.

[0026] The water outlet cover 8 is provided with a common water outlet 12; the common water outlet 12 is interconnected with the high-flow channel 4, and the common water outlet 12 is also interconnected with the low-flow channel 5. The water outlet cover 8 is welded to the main valve body 1, and the water outlet cover 8 and the main valve body 1 are welded together; the main valve body 1 is provided with a welding groove 13, and the protrusion on the water outlet cover 8 is disposed in the welding groove 13. The water outlet cover 8 and the main valve body 1 are detachably connected, and a sealing element for sealing the two is provided between the water outlet cover 8 and the main valve body 1.

[0027] The specific operation process of this embodiment is as follows: the small flow channel 5 and the large flow channel 4 share a single inlet 2. Each of the small flow channel 5 and the large flow channel 4 is independent of each other, and the flow control component 6 can control the opening and closing of the small flow channel 5 and the large flow channel 4 respectively. In the default state, the rubber core 64 abuts against the hole of the sealing ring frame assembly 9, so that the small flow channel 5 and the large flow channel 4 are both in the open state, and the main valve body 1 is in the closed state. When the washing machine needs to use the corresponding flow rate, it is only necessary to open the flow control component 6 of the corresponding channel through the control panel on the washing machine; when the coil assembly 62 of the corresponding channel is energized, the iron core assembly 63 retracts, causing the rubber core 64 to move away from the sealing ring frame assembly 9, and then the corresponding small flow channel 5 or large flow channel 4 will be in the open state.

[0028] By setting up the high-flow-rate seat component 3, the water flow can be automatically adjusted when the water flows through the high-flow-rate seat body 31. Then, the corresponding high-flow-rate channel 4 opens and the low-flow-rate channel 5 closes, resulting in a larger water flow coming out of the water outlet cover 8.

[0029] Since the small flow seat component 7 is located at the end of the small flow channel 5, the water flow undergoes a flow regulation once after passing through the large flow seat component 3. When the water flow is about to be discharged from the outlet cover 8, the water flow undergoes a second flow regulation once after passing through the small flow seat component 7. At this time, the corresponding large flow channel 4 is closed and the small flow channel 5 is opened, so the water flow from the outlet cover 8 is relatively small.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
