Description

Technical Field

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

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. With the improvement of people's living standards, more and more families have purchased dishwashers, which greatly saves the labor intensity and time of users. Dishwashers generally drive the spray arm to rotate through the water flow, and then spray water to the tableware through the spray arm to achieve the purpose of cleaning the tableware. The spray arm of an existing dishwasher can generally only rotate in one direction, and the position of each flushing is basically the same, resulting in a better cleaning effect on one side of the tableware, but a poor cleaning effect on the other side of the tableware. When some secondary pollutants are washed to the other side of the tableware, it is not easy to clean, and the overall cleaning effect is not ideal.

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

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a water inlet structure of a spray arm assembly, a spray arm assembly and a dishwasher which have a wide coverage and cleans more thoroughly.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] In a first aspect, a water inlet structure of a spray arm assembly is provided, comprising:

[0007] a water inlet chamber having a central water inlet and at least two water outlets;

[0008] A fixed seat is arranged in the water inlet chamber, and a guide channel connected to each water outlet in a one-to-one correspondence is formed on the fixed seat, and each guide channel is connected to a central water inlet arranged on the fixed seat;

[0009] The rotating member is covered above the fixed seat, and its outer periphery is rotatably connected with the outer periphery of the fixed seat, and the interior of the rotating member has a movement channel;

[0010] The conducting component can move along the movement channel under the impact of the water flow, jump from one guiding channel to another guiding channel, and alternately block at least one water outlet.

[0011] The solution provided by the present invention is that the water inlet structure includes a water inlet chamber, a rotating member and a conducting member. A guide channel is provided on the fixed seat in the water inlet chamber, a moving channel is provided on the rotating member, and the conducting member is installed in the moving channel and moves along the guide channel. Under the impact of the water flow and the guidance of the rotating member, the conducting member moves from one guide channel to another, and alternately blocks at least one water outlet. When in use, the water outlet is connected to a spray arm, which can rotate clockwise and counterclockwise, thereby increasing the spray coverage and the cleaning area, and washing more cleanly.

[0012] Further, the rotating member comprises a top wall and two side walls, the movement channel is an accommodating cavity surrounded by the top wall and the two side walls, and the accommodating cavity is arranged at a position above the guide channel;

[0013] After the water flow impact is eliminated, the conducting component moves from the water outlet to the central water inlet along the current driving conduction, pushes the side wall of the moving channel, and drives the rotating part to rotate.

[0014] Furthermore, a limiting portion is provided between the side wall of the motion channel and the outer periphery of the rotating member, and the limiting portion is a horizontally arranged plate-like structure, which controls the conducting component to always jump to the adjacent conducting channel in the same direction in the circumferential direction.

[0015] Furthermore, a blocking portion is provided in the accommodating cavity for blocking the conducting component from entering the central water inlet.

[0016] Furthermore, the blocking portion is at least one inclined structure inclined from the top wall toward the central water inlet.

[0017] Furthermore, the conducting component is a spherical structure, and the diameter of the conducting component is larger than the minimum distance from the outer peripheral edge of the central water inlet to the inclined surface structure.

[0018] Furthermore, the fixing seat extends upwardly and obliquely from the outer periphery of the central water inlet along the radial direction of the central water inlet.

[0019] Furthermore, the water inlet chamber also includes a shell, which is covered above the rotating member, and the outer peripheral edge of the shell is sealed and connected to the outer periphery of the fixing seat.

[0020] In a second aspect, a spray arm assembly including the water inlet structure of the spray arm assembly is also provided, wherein at least two spray arm bodies are extended outward from the edge of the shell, and the water outlets are arranged in a one-to-one correspondence with the spray arm bodies and are connected. In a third aspect, the present invention also provides a dishwasher, which includes the spray arm assembly.

[0021] According to the solution provided by the present invention, since the above-mentioned spray arm assembly is installed on the dishwasher, the spray arm can rotate alternately in positive and negative directions, the spray range is larger, and the washing is cleaner.

[0022] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0023] 1. The water inlet structure of the spray arm assembly provided by the present invention includes a water inlet chamber, a rotating member and a conducting component. A guide channel is provided on the fixed seat of the water inlet chamber, a moving channel is provided on the rotating member, and the conducting component is installed in the moving channel and moves along the guide channel. Under the impact of the water flow and the guidance of the rotating member, it moves from one guide channel to another, alternately blocking at least one water outlet. When in use, a spray arm with spray holes in different directions is connected to the water outlet, so that the spray arm can rotate clockwise and counterclockwise, increasing the spray coverage and cleaning area, and washing more cleanly.

[0024] 2. The water inlet structure of the spray arm assembly provided by the present invention has a top wall and side walls on the moving channel. When the conducting component moves from the water outlet toward the central water inlet, it pushes the side walls of the moving channel, driving the rotating part to move from the position of one water outlet to the position of another water outlet.

[0025] 3. The water inlet structure of the spray arm assembly provided by the present invention has a limiter on the rotating part to control the conductive component so that it will not move away from the water inlet under the impact of the water flow. This solution sets the limiter so that the conductive component can only move in the movement channel.

[0026] 4. The water inlet structure of the spray arm assembly provided by the present invention can prevent the conducting component from blocking the central water inlet and can also prevent the conducting component from being washed out of the central water inlet by water flow and randomly blocking the water outlet because a blocking portion is provided on the rotating part.

[0027] 5. The spray arm assembly provided by the present invention adopts the above-mentioned water inlet structure, so that the spray arm can rotate alternately in forward and reverse directions, thereby increasing the spray coverage area and the cleaning area and improving the cleaning effect.

[0052] Embodiment 1

[0053] like Figure 1 As shown, this embodiment provides a water inlet structure 2 of a spray arm assembly.

[0054] The water inlet structure 2 of the spray arm assembly provided in this embodiment includes:

[0055] A water inlet chamber having a central water inlet 204 and at least two water outlets 205;

[0056] A fixed seat 201 is disposed in the water inlet chamber, and a guide channel 206 corresponding to each water outlet 205 is formed on the fixed seat 201, and each guide channel 206 is connected to the central water inlet 204 disposed on the fixed seat 201;

[0057] The rotating member 202 is covered above the fixed seat 201, and its outer periphery is rotatably connected with the outer periphery of the fixed seat 201. The interior of the rotating member 202 has a movement channel 2021;

[0058] The conducting component 203 can move along the movement channel 2021 under the impact of the water flow, jump from one guiding channel 206 to another guiding channel 206, and alternately block at least one water outlet 205.

[0059] The solution provided in this embodiment includes a water inlet chamber, a rotating member 202 and a conducting member 203. The water inlet chamber includes a fixed seat 201 and a rotating member 202. A central water inlet 204 is provided in the middle area of ​​the fixed seat 201, and at least two water outlets 205 are provided on the periphery of the water inlet chamber. A guide channel 206 is provided on the fixed seat 201 of the water inlet chamber, one end of which is connected to the central water inlet 204 and the other end is connected to the water outlet 205. A motion channel 2021 is provided on the rotating member 202. The conducting member 203 is installed in the motion channel 2021 and moves along the guiding channel 206. The conducting member 203 can move from one guiding channel 206 to another guiding channel 206 under the impact of the water flow and under the guidance of the rotating member 202, and alternately block at least one water outlet 205. When in use, the water outlet 205 is connected to a spray arm provided with spray holes in different directions, so that the spray arm can rotate clockwise and counterclockwise, thereby increasing the spray coverage and cleaning area, and washing more thoroughly.

[0060] The solution of this embodiment also includes: the rotating member 202 includes a top wall and two side walls, the movement channel 2021 is a receiving cavity surrounded by the top wall and the two side walls, and the receiving cavity is arranged at a position above the guide channel 206;

[0061] After the water flow impact is eliminated, the conducting component 203 moves from the water outlet 205 to the central water inlet 204 along the current driving conduction, pushes the side wall of the moving channel 2021, and drives the rotating member 202 to rotate.

[0062] 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 of the circular structure, and the guide channel 206 is arranged on the bottom wall of the fixed seat 201. The rotating member 202 is covered above the fixed seat 201, and its periphery is rotatably connected to the periphery of the fixed member. The water inlet chamber also includes a shell, which is covered above the rotating member 202, and the outer peripheral edge of the shell is sealed and connected to the 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 and connected to the 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 set on the rotating member 202, and the opening coincides with the setting position of the water outlet 205 on the shell, so that when the conductive component 203 moves to the opening and blocks the corresponding water outlet 205.

[0063] Of course, in other solutions of this embodiment, the shell is a cylindrical structure, the water outlet 205 is arranged on the outer periphery of the shell, and the fixed seat 201 and the rotating member 202 are both arranged inside the shell.

[0064] It is worth noting that in the above scheme, at least two motion channels 2021 are provided on the rotating member 202, and one motion channel 2021 is a receiving cavity surrounded by a top and two side walls, and the receiving cavity is provided at a position above the guide channel 206, and the conducting component 203 is provided in the receiving cavity. When the impact of the water flow on the conducting component 203 is eliminated, the conducting component 203 moves from the water outlet 205 to the central water inlet 204 along the current guide channel, pushing the side wall of the motion channel 2021, driving the rotating member 202 to rotate, and rotating from the position of one water outlet 205 to the position of another water outlet 205 adjacent thereto. Since the conducting component 203 moves along the guide channel 206, the conducting component 203 will lead the rotating member 202 to rotate toward the other water outlet 205.

[0065] In the solution of this embodiment, the number of movement channels 2021 is the same as the number of water outlets 205 and guide channels 206.

[0066] like Figure 2 As shown, the solution of this embodiment also includes: a guide wall 2011 is provided on the fixing seat 201, and 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, and the extension end is located on one side of the water outlet 205, and a guide channel 206 connecting the central water inlet 204 and one of the water outlets 205 is formed between two adjacent guide walls 2011;

[0067] The guide wall 2011 is provided with a transition portion 2013;

[0068] Under the impact of water flow, the conducting component 203 passes over the transition portion 2013 on the guide wall 2011 and enters into another guide channel 206 from one guide channel 206 .

[0069] 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 .

[0070] The following is a detailed description of the above scheme:

[0071] The fixing seat 201 has a bottom wall, and at least two guide walls 2011 are protruding from the bottom wall, and the guide channel 206 is formed between two adjacent guide walls 2011. Specifically, the guide wall 2011 extends from the periphery of the central water inlet 204 to the peripheral area of ​​the fixing seat 201, and the extended end of the guide wall 2011 is located at one side of the water outlet 205.

[0072] The fixing seat 201 is arranged obliquely, and extends upward obliquely from the outer periphery of the central water inlet 204 along the radial direction of the central water inlet 204. In other words, the horizontal height of the central water inlet 204 of the fixing seat 201 is lower than the horizontal height of the outer periphery of the fixing seat 201, and such an arrangement enables the conducting component 203 to move from the water outlet 205 to the central water inlet 204 under the action of its own gravity without being subjected to the force of the impact of the water flow.

[0073] A transition portion 2013 is also provided on the guide wall 2011. When the conducting component 203 is at the edge of the central water inlet 204, water flows. Under the impact of the water flow, the conducting component 203 moves along the guide channel 206 to the position of the transition portion 2013 on the guide wall 2011, and passes over the transition portion 2013 to enter another guide channel 206 from the guide channel 206 where it is located.

[0074] The solution of this embodiment also includes: the guide wall 2011 has a bending portion, and the bending portion is extended along the tangent direction of the central water inlet 204; the jump portion 2013 is arranged on the bending portion and corresponds to the position of the water outlet 205.

[0075] 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;

[0076] 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 .

[0077] The guide wall 2011 further includes a first portion 2012 and a second portion 2014, wherein the first portion 2012, the bent portion and the second portion 2014 are sequentially connected;

[0078] The first portion 2012 and the second portion 2014 both have a certain thickness and are centrally symmetrically arranged relative to the location of the bending portion.

[0079] The extended end of the guide wall 2011 is located on the same side of all the water outlets 205 along the circumference of the fixing seat 201;

[0080] The first part 2012 of the guide wall 2011 is connected to the outer periphery of the central water inlet 204 and extends toward the water outlet 205. The extended end is connected to the bending portion, and the bending portion extends along the tangent direction of the central water inlet 204. The extended end is connected to the second part 2014. The second part 2014 continues to extend toward the water outlet 205, and the end extends to one side of the water outlet 205.

[0081] Next, the specific setting position and shape of the guide wall 211 in the above solution are described in detail:

[0082] The guide wall 2011 is a convex 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 where the water outlet 205 is located. The convex rib has a certain thickness.

[0083] The guide wall 2011 includes three parts, namely a first part 2012, a bending part and a second part 2014 which are connected in sequence, and the connection part is in an arc shape.

[0084] The first part 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 extended end is connected to the bending portion, and the bending portion extends along the tangent direction of the central water inlet 204. The extended end is connected to the second part 2014. The second part 2014 continues to extend toward the water outlet 205, and the end extends to one side of the water outlet 205.

[0085] It is worth noting that the number and position of the guide walls 2011 are arranged in a one-to-one correspondence with the number and position of the water outlets 205. When multiple guide walls 2011 are provided, the extended ends of the second 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 seat 201.

[0086] In the solution of this embodiment, the bending portion on the guide wall 2011 is referred to as the transition portion 2013, which is extended along the tangent direction of the central water inlet 204 and is arranged corresponding to the water inlet. In addition, the extending direction of the bending portion is from a position corresponding to one side of the water inlet to a position corresponding to the other side of the water outlet 205.

[0087] The guide wall 2011 has a first side wall 2015 and a second side wall 2016 at the position of the bent portion, 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. In addition, the first side wall 2015 and the second side wall 2016 have different angles with the inner wall of the fixing seat 201, and 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.

[0088] In the solution of this embodiment, the angle between the second side wall 2016 and the bottom wall of the fixing seat 201 is less than or equal to ninety degrees. The angle between the first side wall 2015 and the bottom wall of the fixing seat 201 is greater than ninety degrees. In other words, the first side wall 2015 is arranged with a slope, and the second side wall 2016 has no slope. When the conducting component 203 moves to the position of the first side wall 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 on the first side wall 2015. Since the second side wall 2016 has no slope, the conducting component 203 cannot move from the position of the second side wall 2016 of the jumping part 2013 to the position of the first side wall 2015.

[0089] 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.

[0090] As a preferred solution of this embodiment, the first portion 2012 and the second portion 2014 of the guide wall 2011 are centrally symmetrically arranged relative to the position of the bending portion.

[0091] 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 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 guide channel 206 in which it is located.

[0092] Combination Figures 1 to 3 As shown, the solution of this embodiment also includes: the rotating member 202 has a movement channel 2021 inside, which can move along the movement channel 2021 under the impact of water flow, jump from one guide channel 206 to another guide channel 206, and alternately block at least one water outlet 205.

[0093] The rotating member 202 includes a top wall and two side walls, and the movement channel 2021 is a receiving cavity surrounded by the top wall and the two side walls, and the receiving cavity is arranged at a position above the guide channel 206;

[0094] After the water flow impact is eliminated, the conducting component 203 moves from the water outlet 205 to the central water inlet 204 along the current driving conduction, pushes the side wall of the moving channel 2021, and drives the rotating member 202 to rotate.

[0095] A limiting portion 2022 is provided between the side wall of the motion channel 2021 and the outer periphery of the rotating member 202. The limiting portion 2022 is a horizontally arranged plate-like structure, which controls the conducting component 203 to always jump to the adjacent conducting channel in the same direction in the circumferential direction.

[0096] A blocking portion 2023 is provided in the accommodating cavity for blocking the conducting component 203 from entering the central water inlet 204 .

[0097] The blocking portion 2023 is at least one inclined structure inclined from the top wall toward the central water inlet 204 .

[0098] 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 peripheral edge of the central water inlet 204 to the inclined surface structure.

[0099] Next, the specific structure of the rotating member 202 described in the above solution is described in detail:

[0100] The rotating member 202 in this embodiment is a circular structure that is covered above the fixed seat 201, and its outer periphery is rotatably connected to the outer periphery of the fixed seat 201. The rotating member 202 has a motion channel 2021 for the conductive component 203 to move. The guide channel 206 is a receiving cavity surrounded by a top wall and two side walls, and the motion channel 2021 is arranged above the guide channel 206.

[0101] The rotating member 202 further includes a limiting portion 2022, which is a plate-like structure arranged between the side wall of the moving channel 2021 and the outer periphery of the rotating member 202, so as to control the conducting member 203 to always jump to the adjacent conducting channel along one direction in the circumferential direction. When in use, the water inlet structure 2 is installed on the spray arm body 1, and the water outlet 205 of the water inlet structure 2 is arranged opposite to the water inlet of the spray arm body 1. When the conducting member 203 moves from the position of the water outlet 205 along the guide channel 206 to the edge of the central water inlet 204, the side wall of the guide channel 206 is pushed to rotate, so that the water inlet on the water inlet structure 2 corresponds to the water inlet on another spray arm body 1. The purpose of setting the limiting portion 2022 is to prevent the conducting member 203 from making irregular movements under the force of the water flow, and to control the conducting member 203 to always jump to the adjacent conducting channel along the same direction in the circumferential direction.

[0102] The rotating member 202 is also provided with a blocking portion 2023, which is an inclined surface structure inclined from the top wall of the accommodating cavity toward the central water inlet 204, so as to prevent the conducting component 203 from moving into the central water inlet 204. In this solution, the conducting component 203 is a spherical structure, and the diameter of the conducting component 203 is greater than the minimum distance from the outer peripheral edge of the central water inlet 204 to the inclined surface structure.

[0103] 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;

[0104] 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 reaching 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;

[0105] After the water inlet stops, the conducting component 203 falls back to the periphery of the central water inlet 204 along the current guiding channel 206 under the action of gravity.

[0106] In the scheme of this embodiment, the conducting component 203 has three states, namely, in normal state, after water inlet starts, and after water inlet stops. When it is in normal state, the conducting component 203 remains at one end of the guide channel 206 close to 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 limit plate. When water inlet starts, water flows into the water inlet chamber through the central water inlet 204, impacting the conducting component 203 to move along the guide channel 206 toward the water outlet 205, and when it reaches the position of the transition part 2013 on the guide wall 2011, it passes over the transition part 2013 and enters another guide channel 206, and continues to move along the guide channel 206 to the water outlet 205 for blocking. When water inlet 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 guide channel 206 to rotate the guide rotating member 202, and the conducting component 203 falls back to the periphery of the central water inlet 204 and is stuck by the blocking part 2023 and stops moving.

[0107] In the above scheme, 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 arranged on the bottom wall of the fixed seat 201, a conducting component 203 is arranged in the moving channel 2021, and a blocking portion 2023 composed of an inclined structure is arranged in the moving channel 2021.

[0108] In the preferred solution of this embodiment, there is a central water inlet 204 in the water inlet chamber, 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, two conducting components 203 are arranged in the movement channel 2021, and two blocking parts 2023 composed of inclined structures are arranged in the movement channel 2021. Among them, the two blocking parts 2023 are inclinedly extended 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 outlets 205 blocked by the conducting components 203.

[0109] In this embodiment, the positions of the extended ends of the two blocking portions 2023 are on the perpendicular midline of the central water inlet 204. Of course, the extended ends can also be at other positions as long as they can block the conductive component 203 from entering the central water inlet 204.

[0110] In the solution provided by this embodiment, the conducting component 203 can jump from one guiding channel 206 to another guiding channel 206 under the impact of water flow, and alternately block the water outlet 205 in at least one water inlet chamber.

[0111] Embodiment 2

[0112] This embodiment provides a spray arm assembly, which includes the water inlet structure 2 of the spray arm assembly described in the above embodiment.

[0113] 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.

[0114] In the above scheme, the spray arm body 1 is directly arranged and connected to the water outlet 205 of the water inlet structure 2 one by one during use, and 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.

[0115] like Figure 4-6 As shown, in another solution of this embodiment, the water inlet structure 2 includes a fixed seat 201 and a rotating member 202 installed on the fixed seat 201, and no housing is provided. The spray arm assembly includes a circular ring structure 208 and a cover body covering the circular ring structure 208, the outer periphery of the fixed seat 201 is fixedly connected to the inner side wall of the circular ring structure 208, at least two spray arm bodies 1 are extended outward from the edge of the circular ring structure 208, and the water outlet 205 is provided corresponding to the spray arm body 1.

[0116] In the solution of this embodiment, the spray arm assembly includes a hollow annular structure 208, and a spray arm body 1 is extended outward from the edge of the annular structure 208, and the spray holes on the two spray arm bodies 1 are arranged in the same direction. Since the two spray arm bodies 1 are arranged on the same horizontal line, the spray holes are arranged upward or downward. A water inlet is arranged at the connection position between the spray arm body 1 and the annular structure. The inner side wall of the annular structure 208 is fixedly connected to the outer periphery of the fixing seat 201, and the water inlet on the spray arm body 1 is arranged corresponding to the water outlet 205.

[0117] When in use, water flows through the central water inlet 204, and the conductive component 203 at the edge of the central water inlet 204 is pushed to the position of the water inlet of the first spray arm body 1 to block the water inlet, and the second spray arm body 1 rotates clockwise to spray water. When the water inlet stops, the conductive component 203 moves from the position of the water inlet toward the central water inlet 204, and pushes the side wall of the moving channel 2021 on the rotating member 202, so that the rotating member 202 rotates, and the water outlet 205 of the water inlet chamber corresponds to the water inlet on the second spray arm body 1. When water flows into the central water inlet 204 again, the conductive component 203 passes over the transition part 2013 to block the water inlet on the second spray arm body 1, so that the second spray arm body 1 does not rotate, and the first spray arm body 1 rotates counterclockwise to spray water.

[0118] The solution provided in this embodiment can control the spray arm to alternately open the water inlet of the first spray arm body 1 and close the water inlet of the second spray arm body 1, open the water inlet of the second spray arm body 1 and close the water inlet of the first spray arm body 1, so that the spray arm body 1 can rotate alternately clockwise and counterclockwise to spray water, thereby increasing the spray area and enhancing the cleaning effect.

[0119] As a preferred implementation scheme of this embodiment: four spray arm bodies 1 are evenly arranged along the edge of the shell;

[0120] Two conducting components 203 are provided, and the two conducting components 203 alternately close or open two spray arm bodies 1 that are arranged opposite to each other.

[0121] In the above scheme, four spray arm bodies 1 are extended outward from the edge of the annular structure 208, and two spray arm bodies 1 on the same horizontal line form a group, and the spray holes on the two groups of spray arms are arranged in different directions. One group of spray holes are arranged in a clockwise direction, and the other group of spray holes are arranged in a counterclockwise direction. A central water inlet 204 is arranged in the water inlet chamber, four guide channels 206 are arranged on the bottom wall of the fixed seat 201, four guide channels 206 are arranged on the bottom wall of the fixed seat 201, two conducting components 203 are arranged in the moving channel 2021, and two blocking parts 2023 composed of inclined structures are arranged in the moving channel 2021.

[0122] When in use, water flows through the central water inlet 204, and the two conducting components 203 at the edge of the central water inlet 204 are pushed to the position of the two water inlets of the first group of spray arm bodies 1 to block the two water inlets, and the second group of spray arm bodies 1 rotates clockwise to spray water. When the water inlet stops, the two conducting components 203 move from the position of the water inlet toward the central water inlet 204, and push the side wall of the moving channel 2021 on the rotating member 202, so that the rotating member 202 rotates, and the water outlet 205 of the water inlet chamber corresponds to the two water inlets on the second group of spray arm bodies 1. When water flows into the central water inlet 204 again, the two conducting components 203 respectively cross the transition parts 2013 on the two guide walls 2011 to block the two water inlets on the second group of spray arm bodies 1, so that the first group of spray arm bodies 1 rotates counterclockwise to spray water.

[0123] 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.

[0124] The solution provided in this embodiment increases the number of spray arm bodies 1, thereby further increasing the spray range and providing a wide spray area.

[0125] 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;

[0126] The spray arm assembly further includes a magnetic attraction member 207 that can generate magnetic attraction force on the magnetic attraction area; the magnetic attraction member 207 is a circular structure and is embedded in the spray arm body 1 at the water outlet 205 .

[0127] The gravity of the spherical structure is greater than the suction force of the magnetic attraction member 207 .

[0128] In the above scheme, a circular magnetic component 207 is embedded at the position of the water inlet of the spray arm body 1, and the magnetic component 207 has a magnetic attraction. The conductive component 203 is a spherical structure, and a magnetic attraction area is provided on the spherical structure. When the spherical structure moves to the position of the water inlet on the spray arm body 1, the magnetic component 207 provides a suction force to the spherical structure, thereby increasing the sealing between the spherical structure and the water inlet. In the scheme of this embodiment, the outer surface of the spherical structure is a magnetic attraction area, so that no matter where the spherical structure is blocked with the water inlet of the spray arm body 1, it can be attracted by the magnetic attraction of the magnetic component 207.

[0129] Regarding the above solution, it is worth noting that the suction force of the magnetic element 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.

[0130] In the solution provided in this embodiment, the spray arm body 1 can rotate clockwise or counterclockwise alternately, thereby increasing the spraying area.

[0131] Embodiment 3

[0132] This embodiment provides a dishwasher, on which the spray arm assembly described in the second embodiment is installed.

[0133] The dishwasher provided in this embodiment is equipped with a motor. The motor starts to control water inflow into the dishwasher. Water flows through the pipeline and the central water inlet 204 into the water inlet chamber, impacts the conductive component 203 in the water inlet chamber to move to the position of the water outlet 205 to block the water outlet 205, and the water flows through the unblocked water outlet 205 into the spray arm body 1, causing the spray arm body 1 to rotate and spray. When the motor stops, water inflow stops, and the conductive component 203 moves along the guide channel 206 to the edge of the central water inlet 204 under the action of its own gravity, and is stuck by the blocking part 2023. When water inflows again, the conductive component 203 is impacted to move to the position of another water outlet 205 to block the other water outlet 205, and the spray arm body 1 corresponding to the unblocked water outlet 205 rotates and sprays.

[0134] In the solution provided in this embodiment, the spray arm can rotate clockwise and counterclockwise alternately, thereby increasing the spray area and making the dishes in the dishwasher cleaner.
