Description

Water inlet structure of spray arm assembly, spray arm assembly and dishwasher Technical Field

[0001] The present invention belongs to the technical field of dishwashers, and in particular relates to a water inlet structure of a spray arm assembly, the spray arm assembly and a dishwasher. Background Art

[0002] A dishwasher is a device that automatically cleans tableware, including bowls, chopsticks, plates, dishes, knives, and forks. As people's living standards improve, more and more families are purchasing dishwashers, which significantly reduces labor and time. Dishwashers typically use water to rotate a spray arm, which then sprays water onto the tableware to clean it. Existing dishwashers have spray arms that generally rotate in only one direction, and the position of each rinse is essentially the same. This results in better cleaning of one side of the tableware, but poor cleaning of the other side. Secondary contaminants that are washed onto the other side of the tableware are difficult to clean, resulting in an unsatisfactory overall cleaning effect.

[0003] In view of this, the present invention is proposed.

[0071] As shown in FIG. 1 to FIG. 6 , embodiments of the present invention provide a water inlet structure 2 of a spray arm assembly, a spray arm assembly having the water inlet structure 2 , and a dishwasher having the spray arm assembly.

[0072] Specifically, the water inlet structure 2 of the spray arm includes:

[0073] The water inlet chamber has a central water inlet 204 and at least two water outlets 205. The water inlet chamber is formed with guide channels 206 corresponding to each water outlet 205. Each guide channel 206 is connected to the central water inlet 204.

[0074] The conducting component 203 can pass from one guiding channel 206 to another guiding channel 206 under the impact of water flow, and alternately block at least one water outlet 205.

[0075] The spray arm assembly of the embodiment of the present invention includes the water inlet structure 2 and at least two spray arm bodies 1 extending outward. The water outlets 205 of the water inlet structure 2 are arranged in a one-to-one correspondence with the spray arm bodies 1 and are connected.

[0076] The dishwasher according to an embodiment of the present invention includes the aforementioned spray arm assembly. During operation, water flows into the water inlet chamber through the central water inlet 204. Under the impact of the water flow, the conducting member 203 can pass from one guide channel 206 to another, alternately blocking at least one water outlet 205. The spray arm body 1 corresponding to the blocked water outlet 205 then stops discharging water. In this way, intermittent water supply allows the water output of different spray arms 1 to be switched.

[0077] Furthermore, the spray arm assembly is rotatably arranged as a whole in the dishwasher. When different spray arm bodies 1 have different water outlet directions, by switching different spray arm bodies 1 to discharge water, the spray arm assembly can be rotated alternately clockwise and counterclockwise, thereby increasing the spray coverage and cleaning area, and washing more cleanly.

[0078] Example 1

[0079] As shown in FIG. 1 to FIG. 3 , this embodiment provides a water inlet structure 2 of a spray arm assembly.

[0080] The water inlet structure 2 of the spray arm assembly provided in this embodiment includes a water inlet chamber, which has a central water inlet 204 and at least two water outlets 205. A guide channel 206 is formed in the water inlet chamber and is connected to each water outlet 205 in a one-to-one correspondence. Each guide channel 206 is connected to the central water inlet 204.

[0081] The water inlet structure 2 further includes a conducting component 203 . The conducting component 203 can pass from one guiding channel 206 to another guiding channel 206 under the impact of water flow, and alternately block at least one water outlet 205 .

[0082] The water inlet structure 2 of the spray arm assembly in this embodiment includes a water inlet chamber and a conducting component 203. A central water inlet 204 is located at the center of the water inlet chamber, and at least two water outlets 205 are provided along the outer edge of the water inlet chamber. A guide channel 206 is also provided within the water inlet chamber. One end of the guide channel 206 is connected to the central water inlet 204, and the other end extends toward the water outlet 205, with the extended end forming the water outlet 205. The number of guide channels 206 provided is the same as the number of water outlets 205.

[0083] The conducting component 203 is arranged in the water inlet chamber and moves in the guide channel 206. When the conducting component 203 is not subjected to the force of the water flow, it can move along the current guide channel 206. That is, it moves from the position of the water outlet 205 along the guide channel 206 to the edge of the central water inlet 204. When the conducting component 203 is subjected to the force of the water flow impact, it will move from the edge of the central water inlet 204 toward the water outlet 205 in a substantially radial direction. While moving, it can cross from the guide channel 206 where it is located into another guide channel 206, thereby moving along another guide channel 206 and finally moving to the corresponding water outlet 205 and blocking it. In other words, with each water outage and water re-intake, the conducting component 203 can alternately block different water outlets 205.

[0084] The solution of this embodiment also includes: the water inlet chamber is provided with a fixing seat 201, the central water inlet 204 is provided in the middle area of ​​the fixing seat 201, at least two guide channels 206 are formed on the fixing seat 201, and the conducting component 203 moves in the guide channels 206.

[0085] As a specific implementation, the fixing seat 201 has a circular structure.

[0086] Furthermore, a rotating member 202 is provided in the water inlet chamber. The rotating member 202 is covered above the fixing seat 201 , and its outer periphery is rotatably connected to the fixing seat 201 .

[0087] When the conducting component 203 is impacted by the water flow, it is guided by the rotating member 202 to pass from one guiding channel 206 into another guiding channel 206 .

[0088] In this embodiment, the water inlet structure 2 further comprises a housing (not shown), which is disposed above the rotating member 202, and the outer periphery of the housing is sealed to the outer periphery of the fixing seat 201. The housing and the fixing seat 201 enclose the water inlet chamber.

[0089] In the above scheme, the water inlet chamber includes a fixed seat 201 and a rotating member 202. The fixed seat 201 is a circular structure, the central water inlet 204 is arranged at the center position of the circular structure, and the guide channel 206 is arranged on the bottom wall of the fixed seat 201. The rotating member 202 cover is arranged above the fixed seat 201, and its outer periphery is rotatably connected to the outer periphery of the fixed seat 201. The water inlet chamber also includes a shell, which is arranged above the rotating member 202, and the outer peripheral edge of the shell is sealed with the outer periphery of the fixed seat 201. That is to say, in the above scheme, the shell is a cylindrical groove structure with an opening facing downward, the rotating member 202 is arranged in the groove, the opening edge of the groove structure is sealed with the outer periphery of the fixed seat 201, and the outer periphery of the shell is provided with a water outlet 205. It is equivalent to that the water inlet chamber is surrounded by the shell and the fixed seat 201, and an opening is provided on the rotating member 202, and the opening corresponds to the setting position of the water outlet 205 on the shell, so that when the conductive component 203 moves to the opening, it can block the corresponding water outlet 205.

[0090] Of course, in other solutions of this embodiment, the shell may also be a cylindrical structure, with the water outlet 205 provided on its periphery, and the fixing seat 201 and the rotating member 202 both provided inside the shell.

[0091] As shown in FIG2 , the solution of this embodiment further includes: a guide wall 2011 is provided on the fixing seat 201. The guide wall 2011 extends from the outer periphery of the central water inlet provided on the fixing seat 201 to the outer peripheral area of ​​the fixing seat 201. The extension end is located on one side of the water outlet 205. A guide channel 206 is formed between two adjacent guide walls 2011 to connect the central water inlet 204 and one of the water outlets 205.

[0092] The guide wall 2011 is provided with a transition portion 2013. When the conducting component 203 is impacted by water flow, it can cross the transition portion 2013 on the guide wall 2011 and enter the other guide channel 206 from one guide channel 206, thereby blocking the water outlet 205 at the end of the other guide channel 206.

[0093] In a specific solution of this embodiment, the fixing seat 201 extends upwardly and obliquely from the outer periphery of the central water inlet 204 along the radial direction of the central water inlet 204 .

[0094] The following describes the above scheme in detail:

[0095] The fixing base 201 has a bottom wall with at least two guide walls 2011 protruding from the bottom wall. The guide channel 206 is formed between two adjacent guide walls 2011. Specifically, the guide walls 2011 extend from the periphery of the central water inlet 204 toward the periphery of the fixing base 201, with the extended end of the guide wall 2011 located on one side of the water outlet 205.

[0096] The fixing base 201 is arranged at an angle, extending upward from the outer periphery of the central water inlet 204 along the radial direction of the central water inlet 204. In other words, the central water inlet 204 of the fixing base 201 is located at a lower level than the outer periphery of the fixing base 201. This arrangement enables the conducting component 203 to move from the water outlet 205 toward the central water inlet 204 under the action of its own gravity without being affected by the impact of the water flow.

[0097] The guide wall 2011 is provided with a transition portion 2013. When the conducting component 203 is at the edge of the central water inlet 204 and water is flowing, the conducting component 203, under the impact of the water flow, moves along the guide channel 206 to the position of the transition portion 2013 on the guide wall 2011, then crosses the transition portion 2013 and enters another guide channel 206 from the current guide channel 206. When the impact of the water flow disappears, the conducting component 203 moves toward the central water inlet 204 under its own weight. At this time, the kinetic energy is insufficient to cross the transition portion 2013 again, and thus it moves along the current guide channel 206 to the edge of the central water inlet 204.

[0098] As shown in Figures 4 to 6 , the water inlet structure 2 provided in this embodiment is applied to a spray arm assembly. It connects to the spray arm body 1 at the water outlet 205, and different spray arm bodies 1 have spray holes with different water outlet directions. When water enters the water inlet chamber from the central water inlet 204, the conductive component 203, impacted by the water flow, blocks some of the water outlets 205, preventing the corresponding spray arm bodies 1 from discharging water, leaving only some spray arm bodies 1 able to spray water. By controlling the intermittent water supply to the water inlet chamber, each time the water flow is interrupted and then restarted, the conductive component 203 switches the currently blocked water outlet 205, thereby switching the spray arm body 1 that is spraying. Because the spray holes on different spray arm bodies 1 discharge water in different directions, the reaction force generated by the water spray also switches direction, allowing the spray arm assembly to rotate alternately clockwise and counterclockwise, increasing the spray coverage and cleaning area, and achieving a cleaner wash.

[0099] The solution of this embodiment also includes: the middle area of ​​the guide wall 2011 has a bending portion, and the bending portion extends along the tangent direction of the central water inlet 204; the jump portion 2013 is arranged on the bending portion, corresponding to the position of the water outlet 205.

[0100] In the above scheme, the jump portion 2013 is set to extend along the tangential direction of the central water inlet 204, and its setting position is basically located in the same radial direction as the water outlet 205, so that the conductive component 203 can move radially when subjected to the impact force of the water flow, and move toward the water outlet 205 after crossing the jump portion 2013 to block the water outlet 205.

[0101] Furthermore, the bent portion has a first side wall 2015 facing the central water inlet 204 and a second side wall 2016 facing the water outlet 205. The angle between the first side wall 2015 and the bottom wall of the fixing seat 201 is greater than the angle between the second side wall 2016 and the bottom wall of the fixing seat 201.

[0102] In the above solution, the angle between the first sidewall 2015 and the bottom wall of the fixing base 201 is larger, making it easier for the conductive component 203 to cross the transition portion 2013 from the side with the first sidewall 2015. However, crossing the transition portion 2013 from the side with the second sidewall 2016 requires greater force. Therefore, when impacted by water flow, the conductive component 203 can easily move radially across the transition portion 2013. However, once the impact of the water flow subsides, the conductive component 203 lacks sufficient force and is blocked by the second sidewall 2016, unable to cross the transition portion 2013. Instead, it moves along the guide channel 206 where it currently resides.

[0103] Furthermore, the guide wall 2011 further includes a first extension portion 2012 and a second extension portion 2014. The first extension portion 2012, the bent portion, and the second extension portion 2014 are sequentially connected. The first extension portion 2012 and the second extension portion 2014 both have a certain thickness.

[0104] In a preferred structure, the first extension portion 2012 and the second extension portion 2014 are centrally symmetrically arranged relative to the position of the bending portion.

[0105] Furthermore, the extended ends of the guide wall 2011 are located on the same side of all water outlets 205 along the circumference of the fixing base 201. One end of the first extension portion 2012 is connected to the outer periphery of the central water inlet 204 and extends toward the water outlet 205, with the extended end connected to the bent portion. The bent portion extends tangentially to the central water inlet 204 and the extended end is connected to the second extension portion 2014. The second extension portion 2014 continues to extend toward the water outlet 205, with the extended end located to one side of the water outlet 205.

[0106] Next, the specific location and shape of the guide wall 2011 in the above solution are described in detail:

[0107] The guide wall 2011 is a rib protruding from the bottom wall of the fixing seat 201 and extending from the outer periphery of the central water inlet 204 along the radial direction of the central water inlet 204 to the position of the water outlet 205. The rib has a certain thickness.

[0108] The guide wall 2011 includes three parts, namely a first extension part 2012, a bending part and a second extension part 2014 which are connected in sequence, and the connection part is in an arc shape.

[0109] The first extension portion 2012 of the guide wall 2011 is connected to the outer periphery of the central water inlet 204, and extends along the radial direction of the central water inlet 204 toward the water outlet 205. The extension end is connected to the bending portion, and the bending portion extends along the tangential direction of the central water inlet 204. The extension end is connected to the second extension portion 2014. The second extension portion 2014 continues to extend toward the water outlet 205, and the end extends to one side of the water outlet 205.

[0110] It is worth noting that the number and position of the guide walls 2011 correspond to the number and position of the water outlets 205. When multiple guide walls 2011 are provided, the extended ends of the second extension portions 2014 of the guide walls 2011 are all located on the same side of all the water outlets 205 along the circumference of the fixing base 201.

[0111] In this embodiment, the bend on the guide wall 2011 is referred to as the transition portion 2013, which extends along a tangent line of the central water inlet 204 and is located corresponding to the water inlet. Furthermore, the bend extends from a position corresponding to one side of a water outlet 205 to a position corresponding to the other side of the water outlet 205.

[0112] The guide wall 2011 has a first side wall 2015 and a second side wall 2016 at the bend position. The first side wall 2015 is arranged toward the central water inlet 204, and the second side wall 2016 is arranged toward the water outlet 205. Furthermore, the first side wall 2015 and the second side wall 2016 have different angles with the inner wall of the fixing base 201. The angle between the first side wall 2015 and the bottom wall of the fixing base 201 is greater than the angle between the second side wall 2016 and the bottom wall of the fixing base 201.

[0113] In the solution of this embodiment, the angle between the second sidewall 2016 and the bottom wall of the fixing base 201 is less than or equal to 90 degrees. The angle between the first sidewall 2015 and the bottom wall of the fixing base 201 is greater than 90 degrees. In other words, the first sidewall 2015 is arranged with a slope, while the second sidewall 2016 has no slope. When the conductive component 203 moves to the position of the first sidewall 2015, under the force of the water flow, it can jump from the guide channel 206 where it is located to another guide channel 206 along the slope of the first sidewall 2015. Because the second sidewall 2016 has no slope, the conductive component 203 cannot move from the position of the second sidewall 2016 of the jumping portion 2013 to the position of the first sidewall 2015.

[0114] In a preferred solution of this embodiment, the angle between the second side wall 2016 and the bottom wall of the fixing base 201 is ninety degrees; the angle between the first side wall 2015 and the bottom wall of the fixing base 201 is one hundred and thirty-five degrees.

[0115] As a preferred solution of this embodiment, the first extension portion 2012 and the second extension portion 2014 of the guide wall 2011 are centrally symmetrically arranged relative to the position of the bending portion.

[0116] The water inlet structure 2 of the spray arm assembly provided by the present invention has a jump portion 2013 extending along the tangent direction of the central water inlet 204, and its extension direction is set corresponding to the water outlet 205, so that the conductive component 203 can move toward the water outlet 205 after crossing the jump portion 2013 to block the water outlet 205. Furthermore, since the bending portion has a first side wall 2015 and a second side wall 2016, the angle between the first side wall 2015 and the bottom wall of the fixing seat 201 is greater than the angle between the second side wall 2016 and the bottom wall of the fixing seat 201, and the first side wall 2015 is arranged to face away from the water outlet 205, when the conducting component 203 moves from the central water inlet 204 toward the water outlet 205, it can cross the transition portion 2013 and move from one guide channel 206 to another guide channel 206 under the impact of the water flow. When the conducting component 203 moves from the water outlet 205 toward the central water inlet 204, it is blocked by the second side wall 2016 and without the force of the water flow, it can only move along the current guide channel 206.

[0117] The solution of this embodiment also includes:

[0118] After water starts to flow in, the rotating member 202 guides the conducting component 203 to jump from one guiding channel 206 to another guiding channel 206;

[0119] After the water inlet stops, the conducting component 203 moves from the water outlet 205 along the current guide channel 206 to the position of the central water inlet 204, driving the rotating member 202 to rotate.

[0120] Furthermore, in combination with Figures 1 to 3, the solution of this embodiment also includes: the interior of the rotating part 202 has a movement channel 2021, and the conducting component 203 can move along the movement channel 2021 under the impact of the water flow, jumping from one guide channel 206 to another guide channel 206, thereby alternately blocking at least one water outlet 205.

[0121] In the above scheme, the conducting component 203 is installed in the moving channel 2021. When subjected to the impact force of the water flow, the conducting component 203 is guided by the moving channel 2021, so that the conducting component 203 moves along the moving channel 2021 and jumps from one guide channel 206 to another guide channel 206.

[0122] Furthermore, the rotating member 202 includes a top wall and two side walls, and an accommodating cavity surrounded by the top wall and the two side walls forms a movement channel 2021. The accommodating cavity is provided at a position above the guide channel 206.

[0123] After the water flow impact stops, the conducting component 203 moves along the current guide channel 206 from the water outlet 205 to the central water inlet 204 and pushes the side wall to drive the rotating member 202 to rotate.

[0124] In the above embodiment, when the conducting member 203 moves from the water outlet 205 toward the central water inlet 204, it pushes the sidewall, thereby driving the rotating member 202 to rotate, causing the end of the movement channel 2021 to rotate from the position of the current water outlet 205 to the position of another adjacent water outlet 205. In this way, the next time water enters the central water inlet 204, the conducting member 203 can move along the movement channel 2021 to block a different water outlet 205.

[0125] In this embodiment, a limiting portion 2022 is provided between the side wall and the outer periphery of the rotating member 202. The limiting portion 2022 is a horizontally arranged plate-like structure, which is used to control the conductive component 203 to always pass from one guide channel 206 to another adjacent guide channel 206 in the same direction in the circumferential direction.

[0126] By providing the limiting portion 2022 , the conducting component 203 can only move within the movement channel 2021 , thereby preventing the conducting component 203 from not moving toward the water outlet 205 when impacted by water flow.

[0127] Furthermore, a blocking portion 2023 is provided in the accommodating cavity for blocking the conducting component 203 from entering the central water inlet 204 .

[0128] The blocking portion 2023 is at least one inclined structure inclined from the top wall toward the central water inlet 204 .

[0129] Specifically, the conducting component 203 is a spherical structure, and the diameter of the conducting component 203 is larger than the minimum distance from the outer edge of the central water inlet 204 to the inclined surface structure.

[0130] By providing a blocking portion 2023 on the rotating part 202, it is possible to prevent the conducting component 203 from blocking the central water inlet 204, and also to prevent the conducting component 203 from being directly flushed out of the movement channel 2021 from the central water inlet 204 by the water flow, resulting in random blocking of some water outlets 205, making the spray arm body 1 for spraying water uncontrollable.

[0131] Next, the specific structure of the rotating member 202 described in the above solution is described in detail:

[0132] The rotating member 202 in this embodiment is a circular structure that covers the fixed base 201, and its outer periphery is rotatably connected to the outer periphery of the fixed base 201. The rotating member 202 has a movement channel 2021 for the conductive component 203 to move. The movement channel 2021 is an accommodating cavity surrounded by the top wall and two side walls of the rotating member 202. The movement channel 2021 is located above the guide channel 206.

[0133] The rotating member 202 also includes a limiting portion 2022, a plate-like structure disposed between the sidewalls of the motion channel 2021 and the outer periphery of the rotating member 202. This limiting portion 2022 controls the conduction member 203 to always circumferentially and consistently enter the adjacent guide channel 206 in one direction. During use, the water inlet structure 2 is installed in the spray arm assembly so that the water outlet 205 of the water inlet structure 2 is positioned directly opposite the water inlet of the spray arm body 1. At this point, the end of the motion channel 2021 is positioned directly opposite the water inlet of a portion of the spray arm body 1. When the conduction member 203 moves from the water outlet 205 along the guide channel 206 toward the edge of the central water inlet 204, it pushes on the sidewalls of the motion channel 2021, driving the rotating member 202 to rotate, causing the end of the motion channel 2021 to rotate until it faces the water inlet of another spray arm body 1. The purpose of providing the limiting portion 2022 is to prevent the conducting component 203 from making irregular movements under the force of the water flow, thereby ensuring that the conducting component 203 always enters the adjacent guide channel 206 in the same direction in the circumferential direction.

[0134] The rotating member 202 is also provided with a blocking portion 2023. This blocking portion 2023 is an inclined surface structure arranged obliquely from the top wall of the accommodating chamber toward the central water inlet 204, and is used to prevent the conductive component 203 from moving into the central water inlet 204. In this embodiment, the conductive component 203 is a spherical structure, and its diameter is greater than the minimum distance from the outer edge of the central water inlet 204 to the inclined surface structure.

[0135] The solution of this embodiment also includes that, under normal conditions, the conducting component 203 is maintained at one end of the guide channel 206 close to the central water inlet 204;

[0136] After water starts to flow in, the conducting component 203 moves along the guide channel 206 under the impact of the water flow, and when it reaches the position of the transition portion 2013, it passes over the transition portion 2013 and enters another guide channel 206, and continues to move along the guide channel 206 to the water outlet 205 for blocking;

[0137] After the water inlet stops, the conducting component 203 falls back to the periphery of the central water inlet 204 along the current guide channel 206 under the action of gravity.

[0138] In the solution of this embodiment, the conducting component 203 has three states: normal state, after water inlet starts, and after water inlet stops. When it is in the normal state, the conducting component 203 remains at one end of the guide channel 206 near the central water inlet 204, that is, the conducting component 203 is stuck in the guide channel 206 at the edge of the central water inlet 204 by the blocking portion 2023. When water inlet starts, water flows into the water inlet chamber through the central water inlet 204, impacting the conducting component 203 and moving along the movement channel 2021 toward the water outlet 205. When it reaches the position of the transition portion 2013 on the guide wall 2011, it will pass over the transition portion 2013 and enter the other guide channel 206, and continue to move along the other guide channel 206 to the water outlet 205 for blocking. When the water supply stops, the conducting component 203 moves along the current guide channel 206 under the action of gravity, and the conducting component 203 pushes the side wall of the moving channel 2021 to rotate the guide member 202. The conducting component 203 falls back to the outer periphery of the central water inlet 204 and is stuck by the blocking part 2023 to stop moving.

[0139] In a specific embodiment, a central water inlet 204 is provided in the water inlet chamber, two water outlets 205 are evenly arranged on the periphery of the water inlet chamber, two guide channels 206 are provided on the bottom wall of the fixed seat 201, a conducting component 203 is provided in the water inlet chamber, and a blocking portion 2023 composed of an inclined surface structure is provided on the inner side of the rotating member 202.

[0140] In the preferred embodiment of the present invention, the water inlet chamber has a central water inlet 204, four water outlets 205 are evenly arranged on the periphery of the water inlet chamber, four guide channels 206 are arranged on the bottom wall of the fixed seat 201, and two conducting components 203 are arranged in the water inlet chamber, and the two conducting components 203 are always located in the two guide channels 206 arranged at intervals. A blocking portion 2023 composed of two inclined structures is arranged on the inner side of the rotating member 202. Among them, the two inclined structures both extend obliquely from the top wall of the accommodating chamber toward the central water inlet 204, and their extended ends abut against each other. It is worth noting that the two inclined structures are arranged opposite to each other and are respectively arranged corresponding to the water outlet 205 blocked by the conducting component 203.

[0141] In this embodiment, the extension ends of the two inclined structures are located on the perpendicular midline of the central water inlet 204. Of course, the extension ends can also be located at other positions as long as they can block the conductive component 203 from entering the central water inlet 204.

[0142] In the solution provided by this embodiment, the conducting component 203 can pass from one guiding channel 206 into another guiding channel 206 under the impact of water flow, alternately blocking the water outlet 205 in at least one water inlet chamber.

[0143] Example 2

[0144] This embodiment provides a spray arm assembly, which includes the water inlet structure 2 of the spray arm assembly described in the first embodiment.

[0145] The solution of this embodiment includes: at least two spray arm bodies 1 are extended outward from the edge of the shell, and the water outlets 205 are arranged in a one-to-one correspondence with the spray arm bodies 1 and are connected.

[0146] In the above scheme, when in use, the spray arm body 1 is directly arranged and connected one by one with the water outlet 205 of the water inlet structure 2. The spray holes on the spray arm body 1 are arranged in different directions, so that the spray arm body 1 can be rotated alternately clockwise or counterclockwise to increase the spray area.

[0147] As shown in Figures 4 to 6 , in another embodiment, the water inlet structure 2 includes a fixed base 201 and a rotating member 202 mounted on the fixed base 201, and no housing is provided. The spray arm assembly instead includes an annular structure 208 and a cover covering the annular structure 208. The outer periphery of the fixed base 201 is fixedly connected to the inner sidewall of the annular structure 208. At least two spray arm bodies 1 are provided extending outward from the edge of the annular structure 208, and the water outlets 205 are provided corresponding to the spray arm bodies 1.

[0148] In one embodiment of this invention, the spray arm assembly includes a hollow, annular structure 208. Two spray arm bodies 1 extend outward from the edge of the annular structure 208, extending along the same straight line. The spray holes on the two spray arm bodies 1 are located on the same side. A water inlet is provided at the connection between the spray arm body 1 and the annular structure. The inner sidewall of the annular structure 208 is fixedly connected to the outer periphery of the mounting base 201, and the water inlet on the spray arm body 1 is located corresponding to the water outlet 205.

[0149] During use, water flows through the central water inlet 204, pushing the conductive component 203 located at the edge of the central water inlet 204 to the water outlet 205 corresponding to the water inlet of one of the spray arm bodies 1, thereby blocking the water outlet 205. Water then flows out of the other spray arm body 1 through the spray hole. The reaction force of the water jet drives the spray arm assembly to rotate in a clockwise direction to spray water. When water stops flowing, the conductive component 203 moves from the current water outlet 205 position toward the central water inlet 204, pushing the side wall of the rotating member 202, causing it to rotate. When water enters the central water inlet 204 again, the conductive component 203 passes over the transition portion 2013 to block the water outlet 205 corresponding to the water inlet of the other spray arm body 1, and the other spray arm body 1 does not discharge water. At this time, the spray arm body 1 that was previously closed discharges water through the spray hole, and uses the reaction force of the water jet to drive the spray arm assembly to rotate in the counterclockwise direction to spray water.

[0150] The solution provided in this embodiment can control the water inlets of the two spray arm bodies 1 to be opened alternately, so that the spray arm assembly can rotate alternately clockwise and counterclockwise to spray water, thereby increasing the spray area and enhancing the cleaning effect.

[0151] As a preferred implementation scheme of this embodiment: four spray arm bodies 1 are evenly arranged along the edge of the shell;

[0152] Two conducting components 203 are provided, and the two conducting components 203 alternately block or open two oppositely arranged water outlets 205, thereby alternately opening or closing two oppositely arranged spray arm bodies 1.

[0153] In the above scheme, four spray arm bodies 1 are arranged outward from the edge of the annular structure 208. Two spray arm bodies 1 extending along the same straight line form a group, and the spray holes on the two groups of spray arms are arranged in different directions. The spray holes in one group are arranged in a clockwise direction, while the spray holes in the other group are arranged in a counterclockwise direction. A central water inlet 204 is provided in the water inlet chamber, four guide channels 206 are provided on the bottom wall of the fixed base 201, two conducting components 203 are provided in the moving channel 2021, and two blocking portions 2023 composed of inclined structures are provided in the moving channel 2021.

[0154] During use, water flows through the central water inlet 204, pushing the two conductive components 203 located at the edges of the central water inlet 204 to the corresponding water outlets 205 of the two spray arm bodies 1 of the first group to block them. The two spray arm bodies 1 of the second group then release water, driving the spray arm assembly to rotate clockwise. When water stops flowing, the two conductive components 203 move from their current positions along the guide channel 206 toward the central water inlet 204, pushing the sidewalls of the rotating member 202 to rotate it. When water flows into the central water inlet 204 again, the two conductive components 203 respectively pass over the transition portions 2013 on the two facing guide walls 2011 and block the corresponding water outlets 205 on the two spray arm bodies 1 of the second group. At this time, the two spray arm bodies 1 of the first group release water, driving the spray arm assembly to rotate counterclockwise and spray water.

[0155] In other solutions of this embodiment, the number of spray arms may be another number greater than or equal to 2, and the number of conductive components 203 may be another number greater than or equal to 1.

[0156] The solution provided in this embodiment increases the number of spray arm bodies 1, thereby further increasing the spray range and widening the spray area.

[0157] The solution of this embodiment also includes: the conductive component 203 is a spherical structure, and a magnetic attraction area is provided on the spherical structure;

[0158] The spray arm assembly further includes a magnetic member 207 capable of generating suction to the magnetic area; the magnetic member 207 is a circular structure and is embedded in the spray arm body 1 at the water outlet 205 .

[0159] The gravity of the conductive component 203 is greater than the suction force generated by the magnetic element 207 .

[0160] In the above solution, a circular magnetic element 207 is embedded at the water inlet of the spray arm body 1. This magnetic element 207 has a magnetic attraction force. The conductive component 203 is a spherical structure with a magnetic area. When the spherical structure moves to the water inlet of the spray arm body 1, the magnetic element 207 exerts a suction force on the spherical structure, improving the seal between the spherical structure and the water outlet 205. In the solution of this embodiment, the entire outer surface of the spherical structure serves as a magnetic attraction area, so that no matter where the spherical structure is blocked from the water inlet of the spray arm body 1, it will be attracted by the magnetic element 207.

[0161] Regarding the above solution, it is worth noting that the suction force of the magnetic component 207 is smaller than the gravity of the spherical structure, so that the spherical structure is no longer affected by the force of the water flow, and the spherical structure can move to the edge of the central water inlet 204 under the action of its own gravity.

[0162] In the solution provided by this embodiment, the spray arm body 1 can rotate clockwise or counterclockwise alternately, thereby increasing the spraying area.

[0163] Example 3

[0164] This embodiment provides a dishwasher, which is equipped with the spray arm assembly described in the second embodiment.

[0165] The dishwasher provided in this embodiment is equipped with a motor. When the motor is started, water is fed into the dishwasher. Water flows through the pipe and the central water inlet 204 into the water inlet chamber, impacting the conductive component 203 in the water inlet chamber to move to the position of the water outlet 205, blocking the water outlet 205. Water flows through the unblocked water outlet 205 into the corresponding spray arm body 1, causing the spray arm body 1 to discharge water and driving the spray arm assembly to rotate and spray. When the motor stops, water intake stops. The conductive component 203, under the action of its own gravity, moves along the guide channel 206 to the edge of the central water inlet 204, where it is stuck by the blocking portion 2023. When water enters again, it impacts the conductive component 203 to move to the position of another water outlet 205, blocking the other water outlet 205. The spray arm body 1 corresponding to the unblocked water outlet 205 discharges water, driving the spray arm assembly to rotate in the opposite direction and spray.

[0166] In the solution provided by this embodiment, the spray arm can rotate clockwise and counterclockwise alternately, thereby increasing the spray area and making the dishes in the dishwasher clean more thoroughly.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention.
