Description

Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a spraying device and cleaning equipment. Background Technology

[0002] A dishwasher is a cleaning device that automatically cleans tableware such as pots, bowls, plates, dishes, knives, forks, and chopsticks. A dishwasher includes a spray arm with spray nozzles. By pressurizing the liquid inside the spray arm, a high-pressure water jet is formed. This high-pressure water jet is ejected from the spray nozzles to rinse the tableware inside the dishwasher.

[0003] In related technologies, the water jets sprayed from the spray nozzles irrigate the same surface area of ​​the tableware throughout the entire washing cycle. As a result, some areas of the tableware may be rinsed multiple times, while other areas may be rinsed less or not at all, leading to uneven cleaning of the tableware surface and insufficient cleaning in certain areas, which in turn affects the user experience. Utility Model Content

[0004] This application provides a spraying device and a cleaning equipment, which can solve the problem of uneven cleaning of tableware surfaces, resulting in insufficient cleaning of certain areas of the tableware.

[0005] In a first aspect, this application provides a spraying device, which includes:

[0006] The upper spray assembly includes a first fixed arm and a first movable arm, wherein the first movable arm is movably connected to the first fixed arm and the first movable arm is provided with a spray nozzle;

[0007] The lower cover assembly includes a second fixed arm and a second movable arm. The second fixed arm is connected to the first fixed arm to form a first cavity for containing liquid. The second movable arm is connected to the first movable arm so that the second movable arm moves synchronously with the first movable arm. The second movable arm and the first movable arm form a second cavity for containing liquid.

[0008] A flexible element is disposed on at least one of the upper spray assembly and the lower cover assembly. The flexible element is used to rotate the first movable arm relative to the first fixed arm to change the spray direction of the spray nozzle.

[0009] The spraying device provided in this application has a first movable arm movably connected to a first fixed arm via a flexible component, allowing the first movable arm to rotate relative to the first fixed arm. The first movable arm is provided with spray nozzles. Therefore, when the first movable arm rotates at different angles relative to the first fixed arm, the spray direction of the spray nozzles can be changed, allowing the spray nozzles to spray different areas of the object to be cleaned. This ensures that the entire surface of the object is uniformly sprayed, improving the cleaning effect.

[0010] Specifically, the first movable arm can rotate at different angles relative to the first fixed arm. During the cleaning process, the first movable arm can continue to rotate, and the first movable arm can rotate at different angles so that the spray direction of the spray nozzles on the first movable arm can continuously change, so that the spray nozzles can be directed toward different areas of the surface to be cleaned, so as to clean the surface to be cleaned evenly and thoroughly.

[0011] It should be noted that, since the first movable arm and the second movable arm are connected to form a second cavity for containing liquid, and the first and second movable arms move synchronously, in this embodiment, when the first movable arm rotates relative to the first fixed arm, the first movable arm can also drive the second movable arm to rotate relative to the first fixed arm. Furthermore, since the first fixed arm and the second fixed arm are connected, the first movable arm can also rotate relative to the second fixed arm during the rotation of the first and second movable arms.

[0012] The upper spray assembly sprays liquid onto the object to be cleaned, thus cleaning it. The lower cover assembly maintains the stability of the spray device. The upper spray assembly and the lower cover assembly are connected so that a first fixed arm and a second fixed arm are connected to form a first cavity for containing liquid, and a first movable arm and a second movable arm are connected to form a second cavity for containing liquid. Both the first and second cavities can store liquid and supply liquid to the spray nozzles.

[0013] According to one embodiment of this application, the first movable arm has a first limit position and a second limit position relative to the first fixed arm, and the first movable arm rotates between the first limit position and the second limit position.

[0014] When the first movable arm is in the first extreme position, there is a first included angle between the first movable arm and the first fixed arm; when the first movable arm is in the second extreme position, there is a second included angle between the first movable arm and the first fixed arm.

[0015] In this embodiment of the application, by setting a first limit position and a second limit position, the range of motion of the first movable arm can be constrained, so as to reduce the possibility that the first movable arm may over-movement and collide with the bottom wall of the object to be cleaned or the cleaning equipment during the rotation of the first movable arm relative to the first fixed arm, thereby affecting the rotation performance of the first movable arm.

[0016] Furthermore, when the first movable arm moves beyond the first and second limit positions, the spray nozzles on the first movable arm are prone to deviating from the object to be cleaned, thereby affecting the spray range of the object to be cleaned and thus affecting the cleaning effect.

[0017] According to one embodiment of this application, the first extreme position and the second extreme position are respectively located on both sides of the first fixed arm along the first direction.

[0018] In this embodiment of the application, when the first movable arm moves between the first extreme position and the second extreme position relative to the first fixed arm, the first movable arm can gradually move closer to or further away from the object to be cleaned, so as to change the spray direction of the spray nozzle on the first movable arm, thereby cleaning different surfaces of the object to be cleaned and improving the cleaning effect.

[0019] Furthermore, the first fixed arm can correspond to the central area of ​​the placement platform. The spray nozzles on the first fixed arm can primarily be used to spray the central area of ​​the placement platform. When the first movable arm moves towards the object to be cleaned, some spray nozzles on the first movable arm can correspond to the central area of ​​the placement platform, and some spray nozzles on the first movable arm can correspond to the edge area of ​​the placement platform. When the first movable arm moves away from the object to be cleaned, the rotation of the first movable arm changes the spray direction of the spray nozzles on the first movable arm. Most of the spray nozzles on the first movable arm can correspond to the edge area of ​​the placement platform, and can also spray a portion of the outer periphery of the placement platform. Therefore, by moving the first fixed arm and the first movable arm between the first and second extreme positions, the spray range of the spraying device can be expanded. Even when part of the object to be cleaned is offset or exposed outside the placement platform, by moving the first movable arm between the first and second extreme positions, uniform and thorough cleaning of the surface of the object to be cleaned can be achieved.

[0020] According to one embodiment of this application, the first extreme position is closer to the object to be cleaned than the second extreme position, and the first included angle is smaller than the second included angle.

[0021] In this embodiment, when the first movable arm moves toward the object to be cleaned, more spray nozzles on the first movable arm correspond to the middle area of ​​the placement platform, and the spray nozzles on the first fixed arm can be mainly used to spray the middle area of ​​the placement platform. Therefore, the first included angle m of the first movable arm rotating relative to the first fixed arm at the first extreme position is set to be small, which can also achieve the cleaning effect on the middle area of ​​the placement platform. Thus, the driving force for the first movable arm to rotate toward the first fixed arm can also be small, so as to reduce energy consumption.

[0022] By setting a larger second included angle n relative to the first fixed arm when the first movable arm rotates at the second extreme position, more spray nozzles on the first movable arm can correspond to the edge area of ​​the placement table when the first movable arm moves away from the object to be cleaned. This allows for spraying of the edge area of ​​the placement table and a portion of the outer periphery of the edge area, thereby increasing the spraying range and ensuring thorough cleaning of the object, which is beneficial for improving the cleaning effect.

[0023] According to one embodiment of this application, the lower cover assembly includes the flexible element, and the second movable arm is rotatably connected to the second fixed arm through the flexible element.

[0024] In this embodiment, since the second movable arm moves synchronously with the first movable arm and the second fixed arm is connected to the first fixed arm, when the second movable arm is rotatably connected to the second fixed arm through a flexible member, the first movable arm can rotate relative to the first fixed arm.

[0025] The flexible component allows for a flexible connection between the second movable arm and the second fixed arm, thereby reducing the possibility of abnormal noise during the rotation of the second movable arm.

[0026] According to one embodiment of this application, the upper spray assembly includes an elastic reset member, the first movable arm is connected to the first fixed arm through the elastic reset member, and the elastic reset member is used to move the first movable arm and the second movable arm toward the first extreme position.

[0027] In this embodiment, one of the first limit position and the second limit position can be set as the initial position of the first movable arm. When cleaning is completed, the first movable arm is reset to the initial position by the elastic reset member, so that the first movable arm has a consistent initial state in each cleaning operation. Thus, the first movable arm can maintain the initial position when subsequent cleaning operations are started, which facilitates the control of the first movable arm.

[0028] In some examples, since the first angle between the first movable arm and the first fixed arm at the first extreme position is smaller than the second angle between the first movable arm and the first fixed arm at the second extreme position, the first extreme position can be set as the initial position of the first movable arm.

[0029] For example, when the items to be cleaned are small tableware such as bowls and plates, and are located in the middle area of ​​the placement table, the first movable arm can be held in the first extreme position. Liquids released from both the spray nozzles of the first fixed arm and the first movable arm can act on the items to be cleaned. In this case, it is unnecessary to spray the edge areas of the placement table. The first movable arm does not need to rotate, reducing the possibility of liquid from the spray nozzles of the first movable arm spraying onto the outside of the items to be cleaned, thus affecting the cleaning effect, and also reducing liquid waste.

[0030] When the object to be cleaned is a large piece of tableware such as a pot, the first movable arm moves between the first and second extreme positions. The first fixed arm can clean the middle area of ​​the object, and the first movable arm can clean the edge area of ​​the object, so as to achieve uniform spraying of the entire surface of the object and ensure the cleaning effect.

[0031] According to one embodiment of this application, the second movable arm, the second fixed arm, and the flexible component are injection molded as a single integrated structure.

[0032] In this embodiment, the second movable arm, the second fixed arm, and the flexible component can be integrally formed into a lower cover assembly using injection molding. On one hand, the integral injection-molded structure ensures better reliability of the lower cover assembly, preventing leakage of liquid from the first and second cavities through the connection between the second fixed arm and the second movable arm. On the other hand, the integral injection-molded lower cover assembly saves assembly steps and reduces production costs.

[0033] According to one embodiment of this application, the flexible member includes a first flexible body and a second flexible body; the first movable arm is movably connected to the first fixed arm through the first flexible body; and the second movable arm is movably connected to the second fixed arm through the second flexible body.

[0034] In this embodiment, the first flexible body can be used to achieve a rotatable connection between the first movable arm and the first fixed arm, and the second flexible body can be used to achieve a rotatable connection between the second movable arm and the second fixed arm. When the first movable arm rotates relative to the first fixed arm, since the second movable arm is connected to the first movable arm, the second movable arm also rotates relative to the first fixed arm. Both the first and second flexible bodies can undergo deformation.

[0035] The first and second flexible bodies are flexible, therefore, they do not easily impede the rotation of the first and second movable arms. The first and second movable arms can rotate freely.

[0036] According to one embodiment of this application, the first flexible body and the second flexible body are disposed opposite to each other along a first direction to form a third cavity, the third cavity connecting the first cavity and the second cavity.

[0037] In this embodiment, a third cavity for containing liquid can be formed between the first flexible body and the second flexible body. The third cavity is located between the first cavity and the second cavity. The third cavity can be used to connect the first cavity and the second cavity. Liquid can first enter the first cavity and be sprayed onto the object to be cleaned through a spray nozzle on the first fixed arm. Liquid can enter the second cavity through the third cavity and be sprayed onto the object to be cleaned through a spray nozzle on the first movable arm.

[0038] According to one embodiment of this application, the first movable arm, the first fixed arm, and the first flexible body are injection molded as a single integrated structure; and / or, the second movable arm, the second fixed arm, and the second flexible body are injection molded as a single integrated structure.

[0039] In this embodiment, since the first flexible body and the second flexible body are flexible, and the first movable arm and the second movable arm have their own weight, the support and reset member can be used to keep the first movable arm and the second movable arm at any position between the first limit position and the second limit position, so as to reduce the possibility that the first movable arm and the second movable arm will droop down under their own weight, causing the spray nozzle to fail to correspond to the object to be cleaned and thus affecting the cleaning effect of the object to be cleaned.

[0040] Furthermore, the support reset member can also serve to reset the first movable arm to its first extreme position. When the first movable arm moves from the first extreme position to the second extreme position, the support reset member can deform. When the force driving the first movable arm to rotate is removed, the support reset member restores its deformation so that the first movable arm resets to its first extreme position.

[0041] According to one embodiment of this application, it further includes a support reset member; both ends of the support reset member are respectively connected to the first movable arm and the first fixed arm; and / or, both ends of the support reset member are respectively connected to the second movable arm and the second fixed arm.

[0042] In this embodiment, the first movable arm, the first fixed arm, and the first flexible body can be integrally formed into an upper spray assembly using injection molding. This allows for good sealing between the first movable arm, the first fixed arm, and the first flexible body to prevent leakage. Furthermore, it reduces assembly steps, thereby lowering production costs.

[0043] Similarly, the second movable arm, the second fixed arm, and the second flexible body can be injection molded into a single lower cover assembly. This allows for a good seal between the two components, preventing leakage. Furthermore, it reduces assembly steps and lowers production costs.

[0044] According to one embodiment of this application, it further includes a temperature-controlled deformable member, the two ends of which are respectively located in the first cavity and the second cavity, and the temperature-controlled deformable member is used to drive the first movable arm to rotate between the first limit position and the second limit position when the temperature of the liquid changes.

[0045] Wherein, the two ends of the temperature-controlled deformable component are respectively connected to the first movable arm and the first fixed arm; and / or, the two ends of the temperature-controlled deformable component are respectively connected to the second movable arm and the second fixed arm.

[0046] In this embodiment, the temperature-controlled deformable component is in contact with the liquid in the first and second cavities. When the liquid temperature changes, the temperature-controlled deformable component can deform. The temperature-controlled deformable component can drive the first movable arm to move between a first limit position and a second limit position through its own deformation. In other words, the temperature-controlled deformable component can be used to drive the movement of the first movable arm.

[0047] Specifically, the temperature-controlled deformable component can undergo tensile or contractile deformation under temperature changes. For example, taking a case where both ends of the temperature-controlled deformable component are connected to a first movable arm and a first fixed arm respectively, when the liquid temperature rises and reaches a first preset temperature, the temperature-controlled deformable component can undergo contractile deformation, causing the first movable arm to rotate away from the object to be cleaned; that is, the first movable arm can move from a first extreme position to a second extreme position. The contractile deformation of the temperature-controlled deformable component can increase as the temperature gradually rises. Conversely, when the liquid temperature decreases and reaches a second preset temperature, the temperature-controlled deformable component can undergo tensile deformation, meaning it can gradually return to its original state from a contractile deformation. Through the tensile deformation of the temperature-controlled deformable component, the first movable arm can be extended. The first movable arm can then return to its original state from the second extreme position.

[0048] According to one embodiment of this application, a drive pump is also included, which is capable of adjusting the flow rate of the liquid to drive the first movable arm to move between the first limit position and the second limit position by changing the flow rate of the liquid.

[0049] In this embodiment, the driving pump can be used to change the flow rate of the liquid, so that the first movable arm rotates at different angles relative to the first fixed arm due to the different liquid flow rates. Specifically, when the liquid flow rate is high, a larger driving force can be provided to the first movable arm, thereby increasing the angle between the first movable arm and the first fixed arm. When the liquid flow rate is low, a smaller driving force can be provided to the first movable arm, thereby decreasing the angle between the first movable arm and the first fixed arm.

[0050] According to one embodiment of this application, the support reset member and the upper spray assembly are injection molded as a single unit; and / or, the support reset member and the lower cover assembly are injection molded as a single unit.

[0051] In this embodiment, one end of the support reset member can be integrally formed with the first movable arm through injection molding. The other end of the support reset member can be integrally formed with the first fixed arm through injection molding, thereby making the support reset member and the upper spray assembly an integrally injection molded structure. Similarly, one end of the support reset member can be integrally formed with the second movable arm through injection molding, and the other end of the support reset member can be integrally formed with the second fixed arm through injection molding, thereby making the support reset member and the lower cover assembly an integrally injection molded structure.

[0052] It should be noted that the middle region of the support reset member, away from both ends, may not be injection molded into the first fixed arm and the first movable arm. The middle region of the support reset member can remain movable to allow the first movable arm to reset to its first extreme position.

[0053] Secondly, this application provides a cleaning device comprising:

[0054] The main body of the equipment has a cavity for accommodating the object to be cleaned;

[0055] As described in any of the above embodiments, the spraying device is rotatably connected to the main body of the equipment, and the spraying device is located at the bottom of the main body of the equipment.

[0056] In this embodiment, the spraying device is rotatably connected to the main body of the equipment. Therefore, the spray nozzles on the first fixed arm and the first movable arm can be directed towards different areas of the surface of the object to be cleaned for rinsing. Furthermore, in this embodiment, the first movable arm can also rotate relative to the first fixed arm. Therefore, by rotating the first movable arm, the spray direction of the spray nozzles on the first movable arm can be changed, thereby expanding the range of spray applied to the surface of the object to be cleaned and improving the cleaning effect.

[0057] According to one embodiment of this application, the main body of the device is provided with at least one spray pipe, and the spraying device further includes a water pump, which is used to adjust the flow rate of the cleaning liquid in the spray pipe; at least a portion of the liquid sprayed by the spray pipe can be sprayed toward the first movable arm.

[0058] In this embodiment, a water pump can pressurize the liquid inside the spray pipe. Since at least a portion of the liquid sprayed from the spray pipe can be directed toward the first movable arm, the liquid sprayed from the spray pipe can be used to drive the first movable arm to rotate relative to the first fixed arm, so that the first movable arm can move between a first extreme position and a second extreme position.

[0059] Specifically, by adjusting the pressure of the liquid sprayed by the water pump onto the first movable arm, the rotation angle of the first movable arm relative to the first fixed arm can be adjusted, thereby changing the position of the spray nozzle of the first movable arm corresponding to the object to be cleaned, so as to expand the cleaning area of ​​the object to be cleaned and improve cleaning efficiency.

[0060] The beneficial effects of the spraying device provided in this application are as follows: During the cleaning process, by rotating the first movable arm, the spray nozzles on the first movable arm can correspond to the surfaces of different areas of the object to be cleaned, which helps to increase the spraying area of ​​the surface of the object to be cleaned, so as to avoid the problem of insufficient cleaning caused by local areas not being sprayed, and to improve the uniformity of spraying the object to be cleaned, improve the cleaning effect, and thus improve the user experience.

[0061] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the spraying device and cleaning equipment provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0086] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0087] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0088] A dishwasher is a kitchen appliance that offers advantages such as time and labor saving, strong cleaning power, and water conservation. It can be used to automatically clean tableware, cookware, and dining utensils, collectively referred to as "items to be cleaned" in this application embodiment. It removes dirt and food residue from the items by spraying high-temperature, high-pressure water jets and using liquids. Dishwashers can save time, free up hands, and achieve higher cleaning standards.

[0089] Dishwashers can include functions such as washing, sanitizing, drying, storing, and protecting items to be cleaned. On the one hand, they can clean and sterilize items to improve hygiene and safety. On the other hand, they can also scientifically clean items to extend their lifespan.

[0090] Dishwashers can be categorized into household dishwashers and commercial dishwashers based on their application. Household dishwashers are suitable for families and can meet the daily cleaning needs of household tableware. Commercial dishwashers are suitable for restaurants, hotels, etc., and are larger in size to wash more items in a single cycle. The cleaning equipment provided in this application can be either a household dishwasher or a commercial dishwasher, and is not limited thereto in this application.

[0091] A dishwasher includes a main body for containing items to be cleaned. The main body can be a cabinet structure. Dishes can be placed on a shelf inside the main body. A spray system is located within the main body. Liquid within the spray system can be sprayed from nozzles to form a high-pressure water jet. This high-pressure water jet can be sprayed onto the items to be cleaned to rinse them.

[0092] In related technologies, the water jets sprayed from the spray nozzles correspond to the same surface area of ​​the object to be cleaned throughout the entire washing mode. Therefore, some areas of the object to be cleaned may be rinsed multiple times, while other areas may be rinsed less or not at all, resulting in uneven cleaning of the surface of the object and insufficient cleaning in some areas, which in turn affects the user experience.

[0093] Based on the aforementioned technical problems, the applicant has improved the structure of the existing spraying device. In this embodiment, a flexible component allows the first movable arm to be movably connected to the first fixed arm, and the first movable arm can rotate relative to the first fixed arm. Therefore, during the cleaning process, the rotation of the first movable arm allows the spray nozzles on the first movable arm to correspond to different areas of the surface of the object to be cleaned. This increases the spraying area on the surface of the object to be cleaned, avoiding the problem of insufficient cleaning due to unsprayed areas, improving the uniformity of spraying, enhancing the cleaning effect, and thus improving the user experience.

[0094] The spraying device 100 and cleaning equipment 10 provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0095] See Figures 1 to 5 As shown, the spray device 100 of this application embodiment includes an upper spray assembly 110, a lower cover assembly 120 and a flexible member 130.

[0096] The upper spray assembly 110 may include a first fixed arm 111 and a first movable arm 112. The first movable arm 112 is movably connected to the first fixed arm 111, and the first movable arm 112 is provided with spray nozzles.

[0097] The lower cover assembly 120 includes a second fixed arm 121 and a second movable arm 122. The second fixed arm 121 is connected to the first fixed arm 111 to form a first cavity 100a for containing liquid. The second movable arm 122 is connected to the first movable arm 112 so that the second movable arm 122 moves synchronously with the first movable arm 112. The second movable arm 122 and the first movable arm 112 form a second cavity 100b for containing liquid.

[0098] A flexible member 130 is disposed on at least one of the upper spray assembly 110 and the lower cover assembly 120. The flexible member 130 is used to rotate the first movable arm 112 relative to the first fixed arm 111 to change the spray direction of the spray nozzle.

[0099] In this embodiment, the first movable arm 112 is movably connected to the first fixed arm 111 via a flexible member 130, allowing the first movable arm 112 to rotate relative to the first fixed arm 111. The first movable arm 112 is provided with spray nozzles. Therefore, when the first movable arm 112 rotates at different angles relative to the first fixed arm 111, the spray direction of the spray nozzles can be changed, allowing the spray nozzles to spray different areas of the object to be cleaned, ensuring that the entire surface of the object is uniformly sprayed, thus improving the cleaning effect.

[0100] Specifically, the first movable arm 112 can rotate at different angles relative to the first fixed arm 111. During the cleaning process, the first movable arm 112 can continue to rotate, and the first movable arm 112 can rotate at different angles so that the spray direction of the spray nozzle on the first movable arm 112 can continuously change, so that the spray nozzle can be directed toward different areas of the surface of the object to be cleaned, so as to clean the object evenly and thoroughly.

[0101] It should be noted that, since the first movable arm 112 and the second movable arm 122 are connected to form a second cavity 100b for containing liquid, and the first movable arm 112 and the second movable arm 122 move synchronously, in this embodiment, when the first movable arm 112 rotates relative to the first fixed arm 111, the first movable arm 112 can drive the second movable arm 122 to also rotate relative to the first fixed arm 111. Furthermore, since the first fixed arm 111 is connected to the second fixed arm 121, the first movable arm 112 and the second movable arm 122 can also rotate relative to the second fixed arm 121 during their rotation.

[0102] See in some examples Figure 1As shown, the cleaning equipment 10 includes a main body 200 for housing a spray device 100. The spray device 100 may be located at the bottom of the main body 200. A placement platform 300 for placing items to be cleaned may be provided above the spray device 100. The spray nozzles on the spray device 100 in this embodiment can spray different areas of the placement platform 300.

[0103] The upper spray assembly 110 sprays liquid onto the object to be cleaned above, thus cleaning it. The lower cover assembly 120 maintains the stability of the spray device 100. The connection between the upper spray assembly 110 and the lower cover assembly 120 allows the first fixed arm 111 to connect with the second fixed arm 121, forming a first cavity 100a for containing liquid, and the first movable arm 112 to connect with the second movable arm 122, forming a second cavity 100b for containing liquid. The first cavity 100a and the second cavity 100b can store liquid and supply liquid to the spray nozzles.

[0104] In some examples, the first fixed arm 111 may also be provided with multiple spray nozzles. The first fixed arm 111 can remain stationary. The multiple spray nozzles on the first fixed arm 111 can spray in a fixed direction. For example, the multiple spray nozzles on the first fixed arm 111 can spray areas on the object to be cleaned that are prone to stubborn stains.

[0105] In this configuration, at least two of the multiple spray nozzles on the first fixed arm 111 may have different spray directions to clean different areas of the object to be cleaned. Similarly, at least two of the multiple spray nozzles on the second fixed arm 121 may also have different spray directions.

[0106] In some examples, the first cavity 100a and the second cavity 100b can be interconnected. The first cavity 100a and the second cavity 100b can be supplied with liquid through a single liquid supply pipe to simplify the structure and reduce the space occupied.

[0107] See in some examples Figures 2 to 5 As shown, the number of first movable arms 112 may be, but is not limited to, one. For example, the number of first movable arms 112 may be two. Along the length direction of the first fixed arm 111, the two first movable arms 112 may be located at the two ends of the first fixed arm 111, respectively. The two first movable arms 112 may rotate relative to the first fixed arm 111, respectively.

[0108] In some examples, the second movable arm 122 can be configured in a one-to-one correspondence with the first movable arm 112. For example, there can also be two second movable arms 122. The two second movable arms 122 are respectively connected to the two first movable arms 112 and respectively form the second cavity 100b.

[0109] In some examples, the upper spray assembly 110 and the lower cover assembly 120 may be melted by a heating process, and then pressed and cooled to form a sealed first cavity 100a and a second cavity 100b.

[0110] See also some of the possible implementation methods. Figure 6 and Figure 7 As shown, in this embodiment of the application, the first movable arm 112 has a first limit position and a second limit position relative to the first fixed arm 111. The first movable arm 112 rotates between the first limit position and the second limit position.

[0111] When the first movable arm 112 is in the first extreme position, there is a first included angle m between the first movable arm 112 and the first fixed arm 111. When the first movable arm 112 is in the second extreme position, there is a second included angle n between the first movable arm 112 and the first fixed arm 111.

[0112] In this embodiment of the application, by setting a first limit position and a second limit position, the range of motion of the first movable arm 112 can be constrained, so as to reduce the possibility that the first movable arm 112 may collide with the object to be cleaned or the bottom wall of the cleaning device 10 during the rotation of the first movable arm 112 relative to the first fixed arm 111, thereby affecting the rotation performance of the first movable arm 112.

[0113] Furthermore, when the first movable arm 112 moves beyond the first and second limit positions, the spray nozzles on the first movable arm 112 may deviate from the object to be cleaned, thereby affecting the spray range of the object to be cleaned and thus affecting the cleaning effect.

[0114] It should be noted that the specific dimensions of the first included angle m and the second included angle n are not limited in this embodiment. When the first movable arm 112 moves at the first and second extreme positions, it can be achieved that the spray nozzle can spray the entire surface of the object to be cleaned.

[0115] See also some of the possible implementation methods. Figure 6 and Figure 7 As shown, the first extreme position and the second extreme position in this embodiment of the application can be located on both sides of the first fixed arm 111 along the first direction X, respectively.

[0116] When the spraying device 100 is placed horizontally, the first direction X can refer to the vertical direction.

[0117] In this embodiment of the application, when the first movable arm 112 moves between the first extreme position and the second extreme position relative to the first fixed arm 111, the first movable arm 112 can gradually move closer to or further away from the object to be cleaned, so as to change the spray direction of the spray nozzle on the first movable arm 112, thereby cleaning different surfaces of the object to be cleaned and improving the cleaning effect.

[0118] Furthermore, the first fixed arm 111 can correspond to the middle area of ​​the placement table 300. The spray nozzles on the first fixed arm 111 can be mainly used to spray the middle area of ​​the placement table 300. When the first movable arm 112 moves towards the object to be cleaned, some of the spray nozzles on the first movable arm 112 can correspond to the middle area of ​​the placement table 300, and some of the spray nozzles on the first movable arm 112 can correspond to the edge area of ​​the placement table 300. When the first movable arm 112 moves away from the object to be cleaned, the rotation of the first movable arm 112 causes the spray direction of the spray nozzles on the first movable arm 112 to change. Most of the spray nozzles on the first movable arm 112 can correspond to the edge area of ​​the placement table 300, and can also spray a portion of the outer periphery of the placement table 300. Therefore, by moving the first fixed arm 111 and the first movable arm 112 between the first extreme position and the second extreme position, the spray range of the spraying device 100 can be expanded. Even when part of the object to be cleaned is offset or exposed outside the placement table 300, the surface of the object to be cleaned can be cleaned evenly and thoroughly by moving the first movable arm 112 between the first limit position and the second limit position.

[0119] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, in this embodiment of the application, the first extreme position is closer to the object to be cleaned than the second extreme position. The first included angle m is smaller than the second included angle n.

[0120] The first movable arm 112 rotates within a first included angle m in the direction towards the object to be cleaned. The first movable arm 112 rotates within a second included angle n in the direction away from the object to be cleaned. In other words, referring to... Figure 6 and Figure 7 As shown, the first movable arm 112 can reach the first limit position by rotating upward, and the first movable arm 112 can reach the second limit position by rotating downward.

[0121] In this embodiment, when the first movable arm 112 moves toward the object to be cleaned, more spray nozzles on the first movable arm 112 correspond to the middle area of ​​the placement platform 300, and the spray nozzles on the first fixed arm 111 can be mainly used to spray the middle area of ​​the placement platform 300. Therefore, the first included angle m of the rotation of the first movable arm 112 relative to the first fixed arm 111 at the first extreme position is set to be small, which can also achieve the cleaning effect on the middle area of ​​the placement platform 300. Thus, the driving force for the first movable arm 112 to rotate toward the first fixed arm 111 can also be small, so as to reduce energy consumption.

[0122] By setting a larger second included angle n relative to the first fixed arm 111 when the first movable arm 112 rotates at the second extreme position, more spray nozzles on the first movable arm 112 can correspond to the edge area of ​​the placement table 300 when the first movable arm 112 moves away from the object to be cleaned. This allows for spraying of the edge area of ​​the placement table 300 and a portion of the outer periphery of the edge area, thereby increasing the spraying range and ensuring thorough cleaning of the object, which is beneficial for improving the cleaning effect.

[0123] See also some of the possible implementation methods. Figure 5 As shown, the lower cover assembly 120 in this embodiment includes a flexible member 130. The second movable arm 122 is rotatably connected to the second fixed arm 121 via the flexible member 130.

[0124] In this embodiment, since the second movable arm 122 moves synchronously with the first movable arm 112 and the second fixed arm 121 is connected to the first fixed arm 111, when the second movable arm 122 is rotatably connected to the second fixed arm 121 through the flexible member 130, the first movable arm 112 can rotate relative to the first fixed arm 111.

[0125] The flexible component 130 allows for a flexible connection between the second movable arm 122 and the second fixed arm 121, thereby reducing the possibility of abnormal noise during the rotation of the second movable arm 122.

[0126] It should be noted that the power source for the first movable arm 112 and the second movable arm 122 is not limited in this embodiment. For example, the first movable arm 112 can rotate relative to the first fixed arm 111 by changing the liquid pressure in the second cavity 100b. Alternatively, at least one of the first movable arm 112 and the second movable arm 122 may be provided with a drive structure to drive the first movable arm 112 to move between a first limit position and a second limit position.

[0127] See in some examples Figure 8 and Figure 9As shown, when the second movable arm 122 is rotatably connected to the second fixed arm 121 via the flexible member 130, the first movable arm 112 and the first fixed arm 111 can be rotatably connected via the pin 160. Alternatively, the first movable arm 112 and the first fixed arm 111 can also be connected via the flexible member 130, which is not limited in this embodiment.

[0128] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, the upper spray assembly 110 of this application embodiment includes an elastic reset member 113. The first movable arm 112 is connected to the first fixed arm 111 via the elastic reset member 113. The elastic reset member 113 is used to move the first movable arm 112 and the second movable arm 122 toward a first extreme position.

[0129] In this embodiment, one of the first limit position and the second limit position can be set as the initial position of the first movable arm 112. When cleaning is completed, the first movable arm 112 is reset to the initial position by the elastic reset member 113, so that the first movable arm 112 has a consistent initial state in each cleaning operation. Thus, the first movable arm 112 can maintain the initial position when subsequent cleaning operations are started, thereby facilitating the control of the first movable arm 112.

[0130] In some examples, since the first angle between the first movable arm 112 and the first fixed arm 111 at the first extreme position is smaller than the second angle between the first movable arm 112 and the first fixed arm 111 at the second extreme position, the first extreme position can be set as the initial position of the first movable arm 112.

[0131] For example, when the items to be cleaned are small tableware such as bowls and plates, and are located in the middle area of ​​the placement table 300, the first movable arm 112 can be held in the first extreme position. The liquid released from the spray nozzles of both the first fixed arm 111 and the first movable arm 112 can act on the items to be cleaned. In this case, it is unnecessary to spray the edge areas of the placement table 300. The first movable arm 112 does not need to rotate, thus reducing the possibility of liquid from the spray nozzles of the first movable arm 112 spraying onto the outside of the items to be cleaned, thereby affecting the cleaning effect, and also reducing liquid waste.

[0132] When the object to be cleaned is a large piece of tableware such as a pot, the first movable arm 112 moves between the first limit position and the second limit position. The first fixed arm 111 can clean the middle area of ​​the object to be cleaned, and the first movable arm 112 can clean the edge area of ​​the object to be cleaned, so as to achieve uniform spraying of the entire surface of the object to be cleaned, thereby ensuring the cleaning effect of the object to be cleaned.

[0133] In some examples, the elastic reset member 113 may be, but is not limited to, a spring. When the first movable arm 112 is driven away from the first limit position, the elastic reset member 113 can generate elastic deformation. When the driving force on the first movable arm 112 is removed, the elastic reset member 113 can release elastic potential energy to drive the first movable arm 112 back to the first limit position.

[0134] For example, one end of the elastic reset member 113 is connected to the first movable arm 112, and the other end of the elastic reset member 113 is connected to the first fixed arm 111.

[0135] In some feasible ways, the second movable arm 122, the second fixed arm 121, and the flexible member 130 in this application embodiment are injection molded as a single integrated structure.

[0136] In this embodiment, the second movable arm 122, the second fixed arm 121, and the flexible component 130 can be integrated into a lower cover assembly 120 by injection molding.

[0137] On the one hand, the injection-molded one-piece structure ensures the lower cover assembly 120 has good reliability, preventing liquid leakage from the first cavity 100a and the second cavity 100b through the second fixed arm 121 and the second movable arm 122. On the other hand, the injection-molded one-piece lower cover assembly 120 can save assembly steps and reduce production costs.

[0138] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, the flexible member 130 in this embodiment includes a first flexible body 131 and a second flexible body 132. The first movable arm 112 is movably connected to the first fixed arm 111 via the first flexible body 131. The second movable arm 122 is movably connected to the second fixed arm 121 via the second flexible body 132.

[0139] In this embodiment, the first flexible body 131 can be used to achieve a rotatable connection between the first movable arm 112 and the first fixed arm 111, and the second flexible body 132 can be used to achieve a rotatable connection between the second movable arm 122 and the second fixed arm 121. When the first movable arm 112 rotates relative to the first fixed arm 111, since the second movable arm 122 is connected to the first movable arm 112, the second movable arm 122 also rotates relative to the first fixed arm 111. Both the first flexible body 131 and the second flexible body 132 can deform.

[0140] The first flexible body 131 and the second flexible body 132 are flexible, therefore, the first flexible body 131 and the second flexible body 132 do not easily hinder the rotation of the first movable arm 112 and the second movable arm 122. The first movable arm 112 and the second movable arm 122 can rotate freely.

[0141] See also some of the possible implementation methods. Figure 2 As shown, the first flexible body 131 and the second flexible body 132 are arranged opposite each other along the first direction X to form a third cavity 100c. The third cavity 100c connects the first cavity 100a and the second cavity 100b.

[0142] In this embodiment of the application, a third cavity 100c for containing liquid can be formed between the first flexible body 131 and the second flexible body 132. The third cavity 100c is located between the first cavity 100a and the second cavity 100b. The third cavity 100c can be used to connect the first cavity 100a and the second cavity 100b.

[0143] The liquid can first enter the first chamber 100a and be sprayed onto the object to be cleaned through the spray nozzle on the first fixed arm 111. The liquid can then enter the second chamber 100b through the third chamber 100c and be sprayed onto the object to be cleaned through the spray nozzle on the first movable arm 112.

[0144] See also some of the possible implementation methods. Figure 10 and Figure 11 As shown, the spray device 100 also includes a support and reset member 140. The two ends of the support and reset member 140 are respectively connected to the first movable arm 112 and the first fixed arm 111. And / or, the two ends of the support and reset member 140 are respectively connected to the second movable arm 122 and the second fixed arm 121.

[0145] In this embodiment, since the first flexible body 131 and the second flexible body 132 are flexible, and the first movable arm 112 and the second movable arm 122 have their own weight, the support and reset member 140 can be used to keep the first movable arm 112 and the second movable arm 122 at any position between the first limit position and the second limit position, so as to reduce the possibility that the first movable arm 112 and the second movable arm 122 will droop downward under their own weight, causing the spray nozzle to be unable to correspond to the object to be cleaned and thus affecting the cleaning effect of the object to be cleaned.

[0146] Furthermore, the support reset member 140 can also reset the first movable arm 112 to the first extreme position. When the first movable arm 112 moves from the first extreme position to the second extreme position, the support reset member 140 can deform. When the force driving the first movable arm 112 to rotate is removed, the support reset member 140 restores its deformation so that the first movable arm 112 resets to the first extreme position.

[0147] In some examples, the support reset member 140 may be elastic. The support reset member 140 uses its own elastic force to reset the first movable arm 112 towards the first extreme position. For example, the support reset member 140 may be, but is not limited to, an elastic steel sheet.

[0148] In some examples, the first movable arm 112 can be connected to the first fixed arm 111 via two support reset members 140. The two support reset members 140 can be spaced apart along the width direction of the first fixed arm 111.

[0149] It should be noted that at least one of the first movable arm 112 and the second movable arm 122 can be maintained between a first extreme position and a second extreme position by means of the support and reset member 140. This includes: the first movable arm 112 and the first fixed arm 111 can be connected by the support and reset member 140, while the second movable arm 122 and the second fixed arm 121 can be connected solely by the second flexible body 132. Alternatively, the second movable arm 122 and the second fixed arm 121 can be connected by the support and reset member 140, while the first movable arm 112 and the first fixed arm 111 can be connected solely by the first flexible body 131. Furthermore, the first movable arm 112 and the first fixed arm 111 are connected by the support and reset member 140. The second movable arm 122 and the second fixed arm 121 are also connected by the support and reset member 140.

[0150] In some feasible embodiments, the first movable arm 112, the first fixed arm 111, and the first flexible body 131 are injection-molded integral structures. And / or, the second movable arm 122, the second fixed arm 121, and the second flexible body 132 are injection-molded integral structures.

[0151] In this embodiment, the first movable arm 112, the first fixed arm 111, and the first flexible body 131 can be integrally formed into an upper spray assembly 110 using an injection molding process. The first movable arm 112, the first fixed arm 111, and the first flexible body 131 can achieve good sealing to prevent leakage. Furthermore, this reduces assembly steps and lowers production costs.

[0152] Similarly, the second movable arm 122, the second fixed arm 121, and the second flexible body 132 can be integrated into a single lower cover assembly 120 using injection molding. This allows for a good seal between the second movable arm 122, the second fixed arm 121, and the second flexible body 132 to prevent leakage. Furthermore, it reduces assembly steps and lowers production costs.

[0153] In some examples, the integrated upper spray assembly 110 and the integrated lower spray assembly are disposed opposite each other along a first direction X, and the upper spray assembly 110 and the lower spray assembly are sealed together.

[0154] In this embodiment, the sealing method of the upper spray assembly 110 and the lower spray assembly is not limited. For example, the upper spray assembly 110 and the lower spray assembly can be sealed by means of bonding, heating and welding, etc.

[0155] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, the spray device 100 may further include a temperature-controlled deformable member 150. The two ends of the temperature-controlled deformable member 150 are located within the first cavity 100a and the second cavity 100b, respectively. The temperature-controlled deformable member 150 is used to drive the first movable arm 112 to rotate between a first limit position and a second limit position when the liquid temperature changes. The two ends of the temperature-controlled deformable member 150 are connected to the first movable arm 112 and the first fixed arm 111, respectively. And / or, the two ends of the temperature-controlled deformable member 150 are connected to the second movable arm 122 and the second fixed arm 121, respectively.

[0156] It should be noted that the temperature-controlled deformable component 150 can be located in the upper spray assembly 110. Alternatively, the temperature-controlled deformable component 150 can be located in the lower cover assembly 120. Furthermore, both the upper spray assembly 110 and the lower cover assembly 120 can be provided with the temperature-controlled deformable component 150. This embodiment does not impose any limitations.

[0157] In this embodiment, the temperature-controlled deformable member 150 is in contact with the liquid in the first cavity 100a and the second cavity 100b. When the liquid temperature changes, the temperature-controlled deformable member 150 can deform. The temperature-controlled deformable member 150 can drive the first movable arm 112 to move between the first limit position and the second limit position through its own deformation. In other words, the temperature-controlled deformable member 150 can be used to drive the first movable arm 112 to move.

[0158] Specifically, the temperature-controlled deformable component 150 can undergo tensile or contractile deformation under temperature changes. For example, taking a case where both ends of the temperature-controlled deformable component 150 are connected to the first movable arm 112 and the first fixed arm 111 respectively, when the liquid temperature rises and reaches a first preset temperature, the temperature-controlled deformable component 150 can undergo contractile deformation, causing the first movable arm 112 to rotate away from the object to be cleaned, i.e., the first movable arm 112 can move from a first extreme position to a second extreme position. The contractile deformation of the temperature-controlled deformable component 150 can increase as the temperature gradually rises. Correspondingly, when the liquid temperature decreases and reaches a second preset temperature, the temperature-controlled deformable component 150 can undergo tensile deformation, i.e., the temperature-controlled deformable component 150 can gradually return to its original state from a contractile deformation state. Through the tensile deformation of the temperature-controlled deformable component 150, the first movable arm 112 can be extended. The first movable arm 112 can return to its original state from the second extreme position.

[0159] In some examples, since the temperature-controlled deformable element 150 can be used to drive the first movable arm 112 to rotate between the first and second extreme positions, in other words, the temperature-controlled deformable element 150 can cause the first movable arm 112 to return to the first extreme position. Therefore, the spray device 100 may or may not have an elastic reset element 113, and this embodiment is not limited to this.

[0160] When the spray device 100 is equipped with an elastic reset member 113, the elastic reset member 113 can assist the temperature control deformation member 150 in resetting the first movable arm 112 to the first limit position. Furthermore, since the elastic reset member 113 can be elastic, it can buffer the resetting force of the first movable arm 112, so that the first movable arm 112 can be stably reset.

[0161] In some examples, the temperature-controlled deformable member 150 can reset the first movable arm 112 to the first extreme position, and the temperature-controlled deformable member 150 can also support the first movable arm 112. Therefore, the spray device 100 may or may not have a support reset member 140, and this embodiment is not limited thereto.

[0162] When the spray device 100 is equipped with a support and reset member 140, the support and reset member 140 can provide stable support for the first movable arm 112, so as to share the supporting effect of the temperature control deformation member 150 on the first movable arm 112, which is conducive to improving the service life of the temperature control deformation member 150.

[0163] In some examples, the temperature-controlled deformable element 150 may be, but is not limited to, a shape memory alloy wire. One end of the temperature-controlled deformable element 150 may be attached to the first movable arm 112, and the other end of the temperature-controlled deformable element 150 may be attached to the first fixed arm 111.

[0164] In some possible implementations, the spray device 100 may also include a drive pump. The drive pump can adjust the flow rate of the liquid to drive the first movable arm 112 between a first limit position and a second limit position by changing the flow rate of the liquid.

[0165] In this embodiment, the driving pump can be used to change the flow rate of the liquid, so that the first movable arm 112 rotates relative to the first fixed arm 111 at different angles due to the different liquid flow rates. Specifically, when the liquid flow rate is high, a larger driving force can be provided to the first movable arm 112, thereby increasing the angle between the first movable arm 112 and the first fixed arm 111. When the liquid flow rate is low, a smaller driving force can be provided to the first movable arm 112, thereby decreasing the angle between the first movable arm 112 and the first fixed arm 111.

[0166] It is easy to understand that since the drive pump can be used to drive the first movable arm 112 to move between the first limit position and the second limit position, the spray device 100 may or may not be equipped with a temperature control deformation member 150, and this embodiment is not limited.

[0167] Furthermore, since the drive pump can be used to drive the first movable arm 112 to reset in the direction of the first extreme position, the spray device 100 may be provided with an elastic reset member 113 or a support reset member 140, or it may not be provided with an elastic reset member 113 or a support reset member 140. This embodiment does not impose any limitations.

[0168] In some examples, the drive pump may be connected to at least one of the upper spray assembly 110 and the lower cover assembly 120.

[0169] For example, a drive pump can be connected via a liquid conduit to one of the first chamber 100a, the second chamber 100b, and the third chamber 100c to provide driving force for the liquid within the spray device 100. The drive pump can pressurize the liquid within the spray device 100 to change the flow rate of the liquid, thereby driving the first movable arm 112 to move between a first limit position and a second limit position.

[0170] For example, the drive pump can be a variable frequency pump. The variable frequency pump can change the driving force on the first movable arm 112 by automatically adjusting the pump speed.

[0171] In some possible implementations, the support reset member 140 and the upper spray assembly 110 are injection molded as a single unit. And / or, the support reset member 140 and the lower cover assembly 120 are injection molded as a single unit.

[0172] In this embodiment, one end of the support reset member 140 can be integrally formed with the first movable arm 112 through injection molding. The other end of the support reset member 140 can be integrally formed with the first fixed arm 111 through injection molding, thereby making the support reset member 140 and the upper spray assembly 110 an integrally injection molded structure. Similarly, one end of the support reset member 140 can be integrally formed with the second movable arm 122 through injection molding. The other end of the support reset member 140 can be integrally formed with the second fixed arm 121 through injection molding, thereby making the support reset member 140 and the lower cover assembly 120 an integrally injection molded structure.

[0173] It should be noted that the middle region of the support reset member 140, away from both ends, may not be injection molded into the first fixed arm 111 and the first movable arm 112. The middle region of the support reset member 140 can remain movable to allow the first movable arm 112 to be reset to the first limit position.

[0174] This application also provides a cleaning device 10, see [link to relevant documentation] Figure 1 As shown, the cleaning equipment 10 may include the equipment body 200 and the spray device 100 in any of the above embodiments.

[0175] The main body 200 has a space to accommodate the object to be cleaned. The spray device 100 is rotatably connected to the main body 200. The spray device 100 can be located at the bottom of the main body 200.

[0176] In this embodiment, the spray device 100 is rotatably connected to the main body 200. Therefore, the spray nozzles on the first fixed arm 111 and the first movable arm 112 can be directed towards different areas of the surface of the object to be cleaned for rinsing. Furthermore, in this embodiment, the first movable arm 112 can also rotate relative to the first fixed arm 111. Therefore, the rotation of the first movable arm 112 can change the spray direction of the spray nozzles on the first movable arm 112, thereby expanding the range of spray applied to the surface of the object to be cleaned and improving the cleaning effect.

[0177] In some examples, the number of spray devices 100 may be, but is not limited to, one.

[0178] In some possible implementations, at least one spray pipe is provided within the main body 200. The spray device 100 may also include a water pump. The water pump can be used to regulate the flow rate of the cleaning fluid within the spray pipe. At least a portion of the liquid sprayed from the spray pipe can be directed toward the first movable arm 112.

[0179] In this embodiment, a water pump can pressurize the liquid inside the spray pipe. Since at least a portion of the liquid sprayed from the spray pipe can be directed toward the first movable arm 112, the liquid sprayed from the spray pipe can be used to drive the first movable arm 112 to rotate relative to the first fixed arm 111, so that the first movable arm 112 can move between a first limit position and a second limit position.

[0180] Specifically, by adjusting the pressure of the liquid sprayed by the water pump onto the first movable arm 112, the rotation angle of the first movable arm 112 relative to the first fixed arm 111 can be adjusted, thereby changing the position of the spray nozzle of the first movable arm 112 corresponding to the object to be cleaned, so as to expand the cleaning area of ​​the object to be cleaned and improve the cleaning efficiency.
