Description

Technical Field

[0001] This application relates to the field of washing, and more specifically, to a sprayer steering device, a sprayer, and washing equipment. Background Technology

[0002] Currently, with the continuous improvement of people's living standards, dishwashers have gradually become a common household appliance. They are mainly used for cleaning and drying dishes and other tableware. Using a dishwasher can greatly reduce tedious manual labor. Simply put the dishes into the dishwasher, turn on the tap, press a button, and you can confidently do other things, as the washing process is automatic and requires no supervision. Dishwashers reduce labor intensity and improve work efficiency. To achieve a more ideal cleaning effect, existing spray devices installed in dishwashers are generally rotatable cross-shaped sprayers with multiple spray holes. The sprayer is rotatably connected to the inner drum and connected to the water system. Water in the water system is sprayed out through the spray holes on the sprayer to clean the dishes placed in the inner drum. The rotation of the sprayer is driven by the water flow. However, most existing dishwasher sprayers can only rotate in one direction, resulting in incomplete cleaning.

[0003] Patent CN218186734U discloses a two-way spray device for a dishwasher, which includes a forward-rotating spray nozzle and a reverse-rotating spray nozzle. The forward spray nozzle or the reverse spray nozzle is connected by a valve, thereby realizing the rotation of the sprayer in two directions.

[0004] However, the above structure requires control by a separate valve, which is complex and has poor stability. At the same time, the use of valves also increases production costs. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, and to address the issues that existing bidirectional spray devices require separate valves for control when turning, resulting in complex structures, poor stability, and high valve production costs.

[0006] This invention provides a sprayer steering device, comprising a rotating chamber, a rotating body, and a locking body; the rotating chamber has a water inlet hole on its bottom wall and multiple water outlet holes on its side wall; the rotating chamber has a steering structure on its bottom wall, each steering structure corresponding to one of the water outlet holes; the rotating body is rotatably disposed within the rotating chamber, and the rotating body has a guide portion for the reciprocating motion of the locking body; the locking body is located between the steering structure and the guide portion, and is configured such that when liquid is introduced, it jumps from the current steering structure to an adjacent steering structure and blocks the corresponding water outlet hole of the adjacent steering structure; when liquid is stopped, the locking body drives the rotating body to rotate.

[0007] With the above technical solution, liquid enters the rotating chamber through the inlet hole, and the liquid pushes the locking body from the current turning structure to the adjacent turning structure, blocking the corresponding outlet hole of the adjacent turning structure. When the liquid supply stops, the locking body drives the rotating body to rotate. When the liquid is intermittently supplied, the rotating body rotates once each time it is supplied, and the locking body can block different outlet holes, so that the water outlet direction changes. There is no need to add a control valve, and the cost is low, the structure is simple, and the use is stable.

[0008] In a specific embodiment of the above-mentioned sprayer steering device, the first end of the steering structure is connected to the water outlet, the second end of the steering structure is connected to the water inlet, and the second end of the steering structure is aligned with the water outlet corresponding to the adjacent steering structure.

[0009] When the above technical solution is adopted, after the water flow impacts the positioning body, the positioning body can block the water outlet in the shortest distance. The positioning body requires less kinetic energy from the water flow and the jumping effect of the positioning body is better.

[0010] In a specific embodiment of the above-mentioned sprayer steering device, the steering structure includes guide ribs formed on the bottom wall of the rotating chamber, and a guide channel formed by adjacent guide ribs, wherein the guide ribs are partially placed horizontally between the water inlet and the water outlet.

[0011] In a specific embodiment of the above-mentioned sprayer steering device, the guide rib is formed with a guide slope, which is configured to guide the locking body when the locking body jumps from the current steering structure to the adjacent steering structure.

[0012] When the above technical solution is adopted, the guide ramp can guide the locking body, so that the locking body can jump to the adjacent steering structure when it is impacted by liquid.

[0013] In a specific embodiment of the above-mentioned sprayer steering device, a guide bar is provided at one end of the guide rib near the water outlet.

[0014] When the above technical solution is adopted, the guide bar can keep the locking body in the current steering structure after the water supply stops, and plays a guiding role for the locking body.

[0015] In a specific embodiment of the above-mentioned sprayer steering device, the end of the guide channel near the water outlet is higher than the end near the water inlet.

[0016] When the above technical solution is adopted, after the water supply is stopped, due to the difference in height, the locking body can move from the position of the water outlet to the position of the water inlet. At the same time, the locking body moves from the position of the guide near the water outlet to the position near the water inlet. Since the second end of the steering structure is aligned with the water outlet corresponding to the adjacent steering structure, the rotating body rotates.

[0017] In a specific embodiment of the above-mentioned sprayer steering device, a guide plate is provided on the side of the rotating body facing the water inlet. The guide plate is configured to reflect the liquid entering the rotating chamber through the water inlet, so that a portion of the liquid can enter the guide part and push the locking body.

[0018] When the above technical solution is adopted, the guide plate makes the liquid push against the locking body more forcefully, thereby making the sealing effect between the locking body and the water outlet better.

[0019] In a specific embodiment of the above-mentioned sprayer steering device, the rotating body is further provided with a water guiding part, which is spaced apart from the guide part. The water guiding part is configured such that when the guide part is aligned with one of the water outlet holes, the water guiding part is aligned with the other water outlet hole.

[0020] When the above technical solution is adopted, the water guiding part concentrates the liquid entering the rotating chamber, so that the liquid can reach the water outlet more concentratedly.

[0021] In a specific embodiment of the above-mentioned sprayer steering device, there are four water outlet holes, which are evenly arranged along the circumferential direction of the rotating chamber. There are two guide parts and two water guiding parts, which are evenly spaced along the circumferential direction of the rotating chamber.

[0022] With the above technical solution, four water outlets are the optimal configuration. During operation, water can always be discharged from two water outlets in opposite directions, which can prevent the rotating chamber from tilting and ensure the working stability of the steering device.

[0023] In a specific embodiment of the above-mentioned sprayer steering device, the locking body is spherical.

[0024] When the above technical solution is adopted, the spherical locking body can move easily in the steering structure and guide section, reducing resistance during the movement process.

[0025] The present invention also provides a sprayer, including a forward-rotating spray arm, a reverse-rotating spray arm, and the above-mentioned sprayer steering device. The forward-rotating spray arm and the reverse-rotating spray arm are both connected to the water outlet. The forward-rotating spray arm is provided with a forward-rotating spray hole, and the reverse-rotating spray arm is provided with a reverse-rotating spray hole. The forward-rotating spray arm and the reverse-rotating spray arm are arranged along the circumferential direction of the rotating chamber.

[0026] When the above technical solution is adopted, when water is discharged from the outlet corresponding to the forward-rotating spray arm and not discharged from the outlet corresponding to the reverse-rotating spray arm, the entire sprayer rotates in the forward direction under the action of the forward-rotating spray hole.

[0027] When water flows from the outlet corresponding to the reverse spray arm and not from the outlet corresponding to the forward spray arm, the entire sprayer rotates in the opposite direction under the action of the reverse spray hole.

[0028] When water is discharged from the outlet holes corresponding to the same number of forward-rotating spray arms and the same number of reverse-rotating spray arms, the entire sprayer does not rotate.

[0029] Overall, the sprayer's steering device, forward-rotating spray arm, and reverse-rotating spray arm work together to achieve forward and reverse rotation of the sprayer without the need for a steering valve. The structure is simple, the stability is better, and the production cost is also reduced.

[0030] The present invention also provides a washing device, which includes the above-described sprayer.

[0031] In a specific embodiment of the washing equipment described above, the washing equipment is a dishwasher.

[0032] By employing the aforementioned technical solutions, dishwashers can achieve bidirectional rotation, allowing water and detergent to better reach every corner and improve cleaning effectiveness. Simultaneously, less water and detergent are needed to achieve the same cleaning results, and the number of valves is reduced, thus lowering energy costs. Because reversible dishwashers can clean in two directions simultaneously, they offer faster washing speeds and higher efficiency. Attached Figure Description

Detailed Implementation

[0042] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the sprayer in the specification is described in conjunction with a dishwasher, this application can obviously install the sprayer in other washing equipment, such as washing machines, shoe washing machines, etc. Meanwhile, the liquid in the specification can be water or other solutions with washing functions, such as dish soap, laundry detergent, etc. For ease of description, water is used to refer to solutions with washing functions.

[0043] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "set up," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or other type of connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Additionally, in the description of this application, "multiple" refers to at least two.

[0044] like Figure 1-7As shown, to address the issues of complex structure, poor stability, and high production cost associated with valve control during the turning of a bidirectional spray device, this invention provides a sprayer turning device 1, comprising a rotating chamber 11, a rotating body 12, and a locking body 13. The rotating chamber 11 has a water inlet 15 on its bottom wall and multiple water outlets 111 on its side walls. A turning structure 14 is provided on the bottom wall of the rotating chamber 11, with each turning structure 14 corresponding to a water outlet 111. The rotating body 12 is rotatably disposed within the rotating chamber 11, and a guide portion 121 is provided on the rotating body 12 for the reciprocating movement of the locking body 13. The locking body 13 is located between the turning structure 14 and the guide portion 121, and is configured to, when liquid is introduced, jump from the current turning structure 14 to an adjacent turning structure 14 and block the corresponding water outlet 111 of the adjacent turning structure 14. When liquid is stopped, the locking body 13 drives the rotating body 12 to rotate.

[0045] In application, liquid enters the rotating chamber 11 through the inlet 15, and the liquid pushes the locking body 13 from the current steering structure 14 to an adjacent steering structure 14, blocking the corresponding outlet 111 of the adjacent steering structure 14. When the liquid flow stops, the locking body 13 drives the rotating body 12 to rotate. When liquid is intermittently supplied, the locking body 13 jumps once each time it is supplied, and the locking body 13 can block different outlets 111, thus changing the direction of water flow. In this way, the direction of water flow can be changed without the need to add a valve to control the direction of liquid flow, while being low in cost, simple in structure, and stable in use.

[0046] The following is further reference Figure 1-7 The preferred embodiments of this application are described in conjunction with a sprayer for a dishwasher.

[0047] like Figure 1-7As shown, in a first preferred embodiment of the present invention, the sprayer for a dishwasher includes a rotating chamber 11, a rotating body 12, a locking body 13, a forward-rotating spray arm 2, and a reverse-rotating spray arm 3. The bottom wall of the rotating chamber 11 is provided with a water inlet 15, and four water outlets 111 are evenly spaced on the side wall of the rotating chamber 11. The bottom wall of the rotating chamber 11 is provided with four steering structures 14, each steering structure 14 corresponding to one water outlet 111. The rotating body 12 is rotatably disposed in the rotating chamber 11. The rotating body 12 is provided with a guide part 121 for the reciprocating motion of the locking body 13. There are two guide parts 121. The two guide parts 121 are located in opposite directions. The number of locking bodies 13 is the same as the number of guide parts 121. The locking body 13 is located between the steering structure 14 and the guide part 121. When liquid is introduced, it can jump from the current steering structure 14 to the adjacent steering structure 14 and block the corresponding water outlet 111 of the adjacent steering structure 14. When the liquid is stopped, the locking body 13 drives the rotating body 12 to rotate, so that the guide part 121 is aligned with the adjacent water outlet 111. Both the forward-rotating spray arm 2 and the reverse-rotating spray arm 3 are connected to the water outlet 111. The forward-rotating spray arm 2 is provided with a forward-rotating spray hole 21, and the reverse-rotating spray arm 3 is provided with a reverse-rotating spray hole 31. The forward-rotating spray arm 2 and the reverse-rotating spray arm 3 are arranged at a single interval along the circumferential direction of the rotating chamber 11. When water is discharged from the water outlet 111 connected to the forward-rotating spray arm 2, the entire sprayer rotates in the forward direction. When water is discharged from the water outlet 111 connected to the reverse-rotating spray arm 3, the sprayer rotates in the reverse direction.

[0048] In one possible implementation, liquid enters the rotating chamber 11 through the inlet 15. A portion of the liquid pushes the locking body 13 from the current steering structure 14 connected to the forward-rotating spray arm 2 to the adjacent steering structure 14 connected to the reverse-rotating spray arm 3, blocking the outlet 111 corresponding to the steering structure 14 connected to the reverse-rotating spray arm 3. The remaining liquid is discharged into the forward-rotating spray arm 2 through the two outlets 111 connected to the forward-rotating spray arm 2. When the liquid flow stops, the locking body 13 in the steering structure 14 connected to the reverse-rotating spray arm 3 drives the rotating body 12 to rotate, thereby aligning the locking body 13 with the outlet 111 connected to the forward-rotating spray arm 2. When liquid is introduced again, the locking body 13 jumps into the steering structure 14 connected to the forward-rotating spray arm 2, and blocks the water outlet 111 corresponding to the steering structure 14 connected to the forward-rotating spray arm 2. The remaining liquid is discharged into the reverse-rotating spray arm 3 through the two water outlets 111 connected to the reverse-rotating spray arm 3. When liquid is introduced again, the locking body 13 located in the steering structure 14 connected to the forward-rotating spray arm 2 drives the rotating body 12 to rotate, thereby aligning the locking body 13 with the water outlet 111 connected to the reverse-rotating spray arm 3.

[0049] Therefore, when water is intermittently introduced, the locking body 13 jumps once each time water is introduced, and the locking body 13 can block different water outlets 111, causing the water outlet direction to change. When water is flowing from the water outlet 111 corresponding to the forward-rotating spray arm 2, but not from the water outlet 111 corresponding to the reverse-rotating spray arm 3, the entire sprayer rotates in the forward direction under the action of the forward-rotating spray hole 21. When water is flowing from the water outlet 111 corresponding to the reverse-rotating spray arm 3, but not from the water outlet 111 corresponding to the forward-rotating spray arm 2, the entire sprayer rotates in the reverse direction under the action of the reverse-rotating spray hole 31. Thus, the forward and reverse rotation of the sprayer can be achieved without the need for a directional valve, resulting in a simple structure, better stability, and reduced production costs.

[0050] It should be noted that, for ease of description, the washing equipment described here is based on a dishwasher and is only used to explain the technical principles of this application, not to limit the scope of protection of this application. Both the sprayer using the sprayer steering structure 14 and the washing equipment using the above-described sprayer fall within the scope of protection of this invention. In the above description, the rotating chamber 11, the rotating body 12, and the locking body 13 together constitute the sprayer steering device 1.

[0051] It should be further explained that there are multiple water outlet holes 111, with four water outlet holes 111 being the optimal choice. The number of steering structures 14 is the same as the number of water outlet holes 111, and four steering structures 14 are also the optimal choice. There are multiple locking bodies 13 and multiple guide parts 121, with two locking bodies 13 and two guide parts 121 being the optimal choice each. The total number of forward-rotating spray arms 2 and reverse-rotating spray arms 3 is the same as the number of water outlet holes 111, with two forward-rotating spray arms 2 and two reverse-rotating spray arms 3 being the optimal choice. At the same time, the optimal arrangement is to set them at a single interval along the circumferential direction of the rotating chamber 11. Here, the single interval arrangement means that there is one reverse-rotating spray arm 3 between two forward-rotating spray arms 2 and one forward-rotating spray arm 2 between two reverse-rotating spray arms 3. Of course, the single interval arrangement is not necessary, as long as the water sprayed from the unblocked water outlet holes 111 passes through the forward-rotating spray arm 2 or the reverse-rotating spray arm 3 so that the entire sprayer can rotate. The uniform spacing of the water outlet 111 is not necessary. It is sufficient to have independent water outlets 111 on the side wall of the rotating chamber 11. The uniform spacing is the best choice.

[0052] The relative arrangement of the guide parts 121 is not necessary. The guide parts 121 only need to be aligned with the adjacent water outlet 111 under the action of the locking body 13 after the water supply is stopped. Here, the relative arrangement of the two guide parts 121 is the optimal choice.

[0053] The water outlet of the forward-rotating spray hole 21 should be sufficient to cause the forward-rotating spray arm 2 to rotate in the forward direction along the rotating chamber 11. The two forward-rotating spray arms 2 can also be provided with water outlet holes 111 in other directions, such as perpendicular to the direction of the forward-rotating spray arm 2 or at a certain angle to the forward-rotating spray arm 2. Alternatively, only one forward-rotating spray arm can be provided with a forward-rotating spray hole 21, as long as the above requirements are met. The water outlet of the reverse-rotating spray hole 31 should be sufficient to cause the reverse-rotating spray arm 3 to rotate in the reverse direction along the rotating chamber 11. The two reverse-rotating spray arms 3 can also be provided with water outlet holes 111 in other directions, such as perpendicular to the direction of the reverse-rotating spray arm 3 or at a certain angle to the reverse-rotating spray arm 3. Alternatively, only one reverse-rotating spray arm can be provided with a reverse-rotating spray hole 31, as long as the above requirements are met.

[0054] Figure 2-3 The basic structure and configuration of the steering structure 14 are shown. For example... Figure 2-3 As shown, the first end of the steering structure 14 is connected to the water outlet 111, and the second end of the steering structure 14 is connected to the water inlet 15. The second end of the steering structure 14 is aligned with the water outlet 111 of the adjacent steering structure 14. The steering structure 14 includes guide ribs 141 formed on the bottom wall of the rotating chamber 11, and guide channels 142 formed by adjacent guide ribs 141. The end of the guide channel 142 near the water outlet 111 is higher than the end near the water inlet 15. The guide ribs 141 are partially transversely placed between the water inlet 15 and the water outlet 111.

[0055] It should be noted that the function of the guide rib 141 is to be partially placed horizontally between the water inlet hole 15 and the water outlet hole 111, and to form a guide channel 142 with the adjacent guide rib 141. The specific structure of the guide rib 141 can be selected based on the application scenario, as long as the above requirements are met.

[0056] like Figure 1-3 As shown, in order for the locking body 13 to be able to jump to the adjacent steering structure 14 via the transverse portion of the guide rib 141 when impacted by water, the guide rib 141 preferably also has a guide ramp 143. The guide ramp 143 is configured to guide the locking body 13 when it jumps from the current steering structure 14 to the adjacent steering structure 14. In this way, the guide ramp 143 can guide the locking body 13, thereby enabling the locking body 13 to smoothly jump to the adjacent steering structure 14 when impacted by water.

[0057] It should be noted that the setting of guide ramp 143 is not mandatory. Those skilled in the art can choose whether to set it and the specific structure of guide ramp 143 based on the specific application scenario. Of course, guide ramp 143 can also be omitted.

[0058] In order to keep the locking body 13 in the current turning structure 14 after the water supply is stopped, a guide strip 144 is provided at the end of the guide rib 141 near the water outlet 111. In this way, the guide strip 144 can keep the locking body 13 in the current turning structure 14 after the water supply is stopped, and play a guiding role for the locking body 13.

[0059] It should be noted that the setting of guide bar 144 is not mandatory. Those skilled in the art can choose whether to set it and the specific structure of guide bar 144 based on the specific application scenario. Of course, guide bar 144 can also be omitted.

[0060] To facilitate the movement of the locking body 13, the end of the guide channel 142 near the water outlet 111 is higher than the end near the water inlet 15. Thus, when water flow stops, the difference in height allows the locking body 13 to move from the position of the water outlet 111 to the position of the water inlet 15 under the influence of gravity. Simultaneously, the locking body 13 moves from the position of the guide portion 121 near the water outlet 111 to the position near the water inlet 15. Furthermore, since the second end of the steering structure 14 is aligned with the corresponding water outlet 111 of the adjacent steering structure 14, the rotating body 12 rotates.

[0061] It should be noted that the setting of guide bar 144 is not mandatory. Those skilled in the art can choose whether to set it and the specific structure of guide bar 144 based on the specific application scenario. Of course, guide bar 144 can also be omitted.

[0062] like Figure 1-5 As shown, to increase the thrust on the locking body 13, a guide plate 123 is provided on the side of the rotating body 12 facing the water inlet 15. The guide plate 123 is configured to reflect water entering the rotating chamber 11 from the water inlet 15, so that some water can enter the guide section 121 and push the locking body 13. In this way, the guide plate 123 makes the thrust of water on the locking body 13 greater, thereby making the sealing effect between the locking body 13 and the water outlet 111 better.

[0063] It should be noted that the setting of guide plate 123 is not necessary. Those skilled in the art can choose whether to set it and the specific structure of guide plate 123 based on the specific application scenario. Of course, guide plate 123 can also be omitted.

[0064] like Figure 3-5As shown, in order to concentrate the water entering the rotating chamber 11, the rotating body 12 is also provided with two water guiding parts 122. The water guiding parts 122 are arranged at a single interval from the guide parts 121. The water guiding parts 122 are configured such that when the guide parts 121 are aligned with one water outlet 111, the water guiding parts 122 are aligned with the other water outlet 111. In this way, the water guiding parts 122 concentrate the water entering the rotating chamber 11, so that the water can reach the water outlet 111 more concentratedly.

[0065] It should be noted that there are multiple water guiding parts 122. The specific number of water guiding parts 122 is determined by the number of guide parts 121 and water outlet holes 111. The number of water guiding parts 122 is equal to the number of water outlet holes 111 minus the number of guide parts 121. Here, the optimal choice for water guiding parts 122 is two. The single-interval setting here means that there is one water guiding part 122 between two guide parts 121, and one guide part 121 between two water guiding parts 122. The single-interval setting is not mandatory; it only needs to ensure that when the guide parts 121 are aligned with two water outlet holes 111, the water guiding parts 122 can be aligned with the other two water outlet holes 111. Furthermore, the setting of water guiding parts 122 is not mandatory. Those skilled in the art can choose whether to set them and the specific structure of the water guiding parts 122 based on the specific application scenario. Of course, water guiding parts 122 can also be omitted.

[0066] like Figure 1 As shown, the locking body 13 is spherical. This spherical shape facilitates movement within the steering structure 14 and the guide section 121, reducing resistance during movement.

[0067] It should be noted that the function of the locking body 13 is to move within the steering structure 14 and the guide part 121. The locking body 13 can be elliptical, cylindrical, etc., as long as it can achieve the above purpose. The optimal choice for the locking body 13 is spherical.

[0068] The following describes the preferred embodiment of how the spray arms inside the dishwasher rotate in both directions. Under normal, non-use conditions, the locking body 13 is located in the steering structure 14 near the water inlet 15. When water is introduced, the water is reflected by the guide plate 123, and the water pushes the locking body 13 through the guide ramp 143, leaping into the adjacent steering structure 14. Under the continuous impact of the water, the locking body 13 blocks the two opposing water outlets 111. Under the action of the water guide 122, water flows out from the other two water outlets 111. The two water outlets are connected to two forward-rotating spray arms 2 or two reverse-rotating spray arms 3. When water is sprayed from the forward-rotating spray arm 2, the entire sprayer rotates forward under the reaction force of the sprayed water; when water is sprayed from the reverse-rotating spray arm 3, the entire sprayer rotates in the opposite direction under the reaction force of the sprayed water. When it is necessary to adjust the rotation direction, stop the water supply. The locking body 13 drives the rotating body 12 to rotate, eventually aligning the locking body 13 with the water outlet 111 adjacent to the original water outlet 111, and wait for the next water supply to repeat the above operation.

[0069] The second embodiment of the sprayer for a dishwasher is described below.

[0070] The second preferred embodiment is used in the sprayer of a dishwasher. The rotating chamber 11 has two water outlets 111 on its side wall, one guide portion 121 and one water guiding portion 122, and two steering structures 14 are provided on the bottom wall of the rotating chamber 11, with one forward-rotating spray arm 2 and one reverse-rotating spray arm 3. The two water outlets 111 are arranged opposite each other, the guide portion 121 and the water guiding portion 122 are arranged opposite each other, and the forward-rotating spray arm 2 and the reverse-rotating spray arm 3 are arranged opposite each other. Other arrangements are the same as in the first embodiment.

[0071] It should be noted that the opposing arrangement of the water outlets 111 is not mandatory. It is sufficient that each water outlet 111 is provided on the side wall of the rotating chamber 11; an opposing arrangement is the optimal choice. Similarly, the opposing arrangement of the guide section 121 and the water guide section 122 is not mandatory. It is sufficient that the guide section 121 is aligned with one water outlet 111, and the water guide section 122 is aligned with the other water outlet 111. The opposing arrangement of the forward-rotating spray arm 2 and the reverse-rotating spray arm 3 is not mandatory. It is sufficient that the water sprayed from the unblocked water outlets 111 only passes through either the forward-rotating spray arm 2 or the reverse-rotating spray arm 3.

[0072] The third embodiment of the sprayer for a dishwasher is described below.

[0073] The third preferred embodiment is used in the sprayer of a dishwasher. The rotating chamber 11 has four water outlets 111 on its side wall, two guide sections 121 and two water guiding sections 122, and four steering structures 14 are provided on the bottom wall of the rotating chamber 11, with two forward-rotating spray arms 2 and two reverse-rotating spray arms 3. The four water outlets 111 are evenly spaced, the guide sections 121 and water guiding sections 122 are spaced in pairs along the circumferential direction of the rotating chamber 11, and the forward-rotating spray arms 2 and reverse-rotating spray arms 3 are spaced in pairs along the circumferential direction of the rotating chamber 11. Other configurations are the same as in the first embodiment.

[0074] It should be noted that the uniform spacing of the water outlets 111 is not necessary. It is sufficient to have independent water outlets 111 on the side wall of the rotating chamber 11. The uniform spacing is the optimal choice. Here, "two-by-two spacing" means that two guide parts 121 are adjacent, two water guide parts 122 are adjacent, two forward-rotating spray arms 2 are adjacent, and two reverse-rotating spray arms 3 are adjacent. Other arrangements are the same as in the first embodiment.

[0075] This preferred embodiment achieves bidirectional rotation of the spray arms within the dishwasher. Under normal, non-use conditions, the locking body 13 is located near the water inlet 15 within the steering structure 14. When water is supplied, the water is reflected by the guide plate 123, propelling the locking body 13 through the guide ramp 143 and into the adjacent steering structure 14. Under the continuous impact of the water, the locking body 13 blocks two adjacent water outlets 111. Under the action of the water guide 122, water flows out from the other two water outlets 111. When water is sprayed only from the forward-rotating spray arm 2, the entire sprayer rotates forward due to the reaction force of the sprayed water. When water is sprayed only from the reverse-rotating spray arm 3, the entire sprayer rotates in the opposite direction due to the reaction force of the sprayed water. When water is sprayed from one forward-rotating spray arm 2 and one reverse-rotating spray arm 3, the entire sprayer does not rotate. When it is necessary to adjust the rotation direction, stop the water supply. The locking body 13 drives the rotating body 12 to rotate, eventually aligning the locking body 13 with the water outlet 111 adjacent to the original water outlet 111, and wait for the next water supply to repeat the above operation.

[0076] This invention also provides a washing device that uses the aforementioned sprayer, preferably a dishwasher. This dishwasher can rotate in both directions, allowing water and detergent to better cover every corner, improving cleaning effectiveness. Simultaneously, less water and detergent are needed to achieve the same cleaning effect, and the number of valves is reduced, thus lowering energy costs. Because a reversible dishwasher can clean in two directions simultaneously, its washing speed is faster and its work efficiency is higher.

[0077] It should be noted that washing equipment can also include washing machines, shoe washing machines, etc., but the best choice is a dishwasher.

[0078] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0079] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
