Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a spray device and cleaning equipment. Background Art

[0002] A dishwasher is a device that automatically cleans pots, bowls, plates, dishes, knives, forks, chopsticks, and other tableware. It includes a spray arm with a spray nozzle. Pressurizing the liquid within the spray arm creates a high-pressure water jet, which is ejected from the nozzle to rinse the tableware inside the dishwasher.

[0003] In the related art, the water column sprayed from the spray nozzle flushes the surface area of ​​the same position of the tableware during the entire washing mode. Therefore, part of the tableware may be flushed multiple times, while another part of the tableware may be flushed less times or even not flushed, resulting in uneven cleaning of the tableware surface and insufficient local cleaning, which in turn affects the user experience. Utility Model Content

[0004] The present application provides a spray device and a cleaning device, which can solve the problems of uneven cleaning of the tableware surface and insufficient local cleaning.

[0005] In a first aspect, the present application provides a spray device comprising:

[0006] main boom;

[0007] a movable arm, the movable arm being rotatably connected to the main arm, the movable arm being provided with a spray port, and the movable arm being movable between a first position and a second position relative to the main arm; when the movable arm is in the first position, a first angle is formed between the movable arm and the main arm, and when the movable arm is in the second position, a second angle is formed between the movable arm and the main arm;

[0008] A driving unit is connected to at least one of the main arm and the movable arm, and is used to drive the movable arm to move between the first position and the second position to change the spraying direction of the spray port.

[0009] The spraying device provided in the application comprises a movable arm and a main arm. The movable arm can move relative to the main arm under the driving action of the driving unit, so that the position of the movable arm changes, and the direction of the water column sprayed by the spraying port on the movable arm also changes. Therefore, the water column sprayed by the spraying port can be sprayed to different surface areas of the tableware, so as to expand the range of washing the surface of the tableware, so that the surface of the tableware can be washed, thereby improving the uniformity of the cleaning and washing of the surface of the tableware, reducing the possibility of affecting the cleaning effect caused by insufficient local cleaning, and facilitating the improvement of user experience.

[0010] The spraying port is arranged on the movable arm. The spraying port can spray a water column to wash the tableware by the water column. The driving unit can drive the movable arm to move relative to the main arm between the first position and the second position. The included angle between the movable arm and the main arm is different when the movable arm is located at the first position and the second position, so that the direction of the water column sprayed by the spraying port of the movable arm is different when the movable arm is located at the first position and the second position. Therefore, by changing the included angle between the movable arm and the main arm through the driving unit, the spraying direction of the spraying port can be changed. The water column sprayed by the spraying port can act on different surfaces of the tableware to expand the range of washing the tableware, so that the surface of the tableware can be washed by the water column, which is beneficial to improve the cleaning effect and improve the user experience.

[0011] It should be noted that the first position and the second position of the movable arm refer to the maximum movement range of the movable arm. In the washing mode, the movable arm can keep moving between the first position and the second position. For example, the movable arm can reciprocate between the first position and the second position. The movable arm can have a plurality of different positions between the first position and the second position. The direction of the water column sprayed by the spraying port is different when the movable arm is located at different positions, so as to expand the range of washing the surface of the tableware.

[0012] According to one embodiment of the application, the surface of the main arm towards the to-be-cleaned article is defined as a first surface, and the surface of the movable arm towards the to-be-cleaned article is defined as a second surface;

[0013] When the movable arm is located at the first position, the second surface and the first surface form the first included angle, and the first included angle is a straight angle;

[0014] When the movable arm is located at the second position, the movable arm is inclined to the reverse direction of the spraying direction of the spraying port, the second surface and the first surface form the second included angle, and the second included angle is an acute angle.

[0015] In the embodiments of the present application, when the movable arm is in the first position, the length direction of the movable arm can be the same as the length direction of the main arm. The spraying device can be located below the rack of the tableware. The end of the movable arm away from the main arm can be rotated away from the rack. In other words, the end of the movable arm away from the main arm is rotated downward. In this way, the possibility of the movable arm being upwardly overturned and colliding with the rack can be avoided.

[0016] When the second included angle is greater than or equal to a right angle, the movable arm has a too large rotation angle range, and the water column sprayed by the spraying port on the movable arm will be sprayed more on the inner wall of the equipment body, thereby reducing the water column sprayed on the tableware and causing the phenomenon that the local area of the tableware is not cleaned. Therefore, by setting the second included angle as an acute angle, it can be ensured that sufficient water column can act on the tableware to improve the cleaning effect.

[0017] According to an embodiment of the present application, the movable arm is provided with a first chamber capable of containing liquid, and the first chamber is in communication with the spraying port;

[0018] The driving unit is used to drive the liquid in the first chamber to flow, and the driving unit can adjust the flow rate of the liquid to drive the movable arm to move between the first position and the second position by changing the flow rate of the liquid.

[0019] In the embodiments of the present application, the driving unit can drive the flow rate of the liquid in the first chamber of the movable arm. When the flow rate of the liquid in the first chamber is large, the water column sprayed by the spraying port can have a large scouring force. On the one hand, the large scouring force can act on the tableware to clean stubborn stains on the tableware, which is beneficial to improve the cleaning effect. On the other hand, the large scouring force can have a reaction force on the movable arm, and the movable arm can be subjected to a reverse movement while the spraying port sprays the water column.

[0020] According to an embodiment of the present application, the driving unit includes a water pump, the water pump is in communication with the first chamber through a liquid guide pipe, and the water pump is used to adjust the flow rate of the liquid.

[0021] In the embodiments of the present application, the water pump can be directly used to adjust the flow rate of the liquid in the first chamber. The water pump can convert the power of the motor into the power of the liquid, thereby generating the power to drive the liquid to flow. When the washing mode is started, the water pump can be started. The water pump pressurizes the liquid in the first chamber to increase the flow rate of the liquid in the first chamber, thereby providing driving force for the liquid in the first chamber.

[0022] The water pump can be a variable frequency water pump. The variable frequency water pump can automatically adjust the rotating speed of the water pump to adjust the flow rate of the liquid in the first chamber, so as to drive the movable arm to continuously move between the first position and the second position.

[0023] According to an embodiment of the present application, the driving unit comprises a temperature-controlled deformation member, a first end of the temperature-controlled deformation member being connected to the movable arm, and a second end of the temperature-controlled deformation member being connected to the main arm.

[0024] When the temperature of the temperature-controlled deformation member reaches a first preset temperature, the temperature-controlled deformation member shrinks to drive the movable arm to move towards the second position.

[0025] When the temperature of the temperature-controlled deformation member is lower than a second preset temperature, the temperature-controlled deformation member resets, and the movable arm moves towards the first position.

[0026] In the embodiment of the present application, the temperature-controlled deformation member can generate deformation under temperature change. Since one end of the temperature-controlled deformation member is connected to the main arm, and the other end is connected to the movable arm, when the temperature-controlled deformation member deforms, it can drive the movable arm to move relative to the main arm.

[0027] Specifically, when the temperature of the temperature-controlled deformation member rises to reach the first preset temperature, the temperature-controlled deformation member can generate shrinkage deformation. The end of the temperature-controlled deformation member connected to the movable arm can drive the movable arm to deflect towards the main arm. In other words, when the temperature rises, the shrinkage of the temperature-controlled deformation member can drive the movable arm to move from the first position to the second position. Correspondingly, when the temperature of the temperature-controlled deformation member drops to the second preset temperature, the temperature-controlled deformation member can generate tensile deformation. The end of the temperature-controlled deformation member connected to the movable arm can drive the movable arm to deflect away from the main arm. In other words, when the temperature drops, the temperature-controlled deformation member can drive the movable arm to move from the second position to the first position. When the washing mode ends, the temperature of the temperature-controlled deformation member gradually cools down, and the temperature-controlled deformation member can drive the movable arm to reset towards the first position.

[0028] Therefore, through the shrinkage and tensile deformation of the temperature-controlled deformation member, the movable arm can be driven to flip relative to the main arm to change the spray direction of the spray opening of the movable arm, so as to expand the surface area of the tableware sprayed and improve the cleaning uniformity.

[0029] According to an embodiment of the present application, the movable arm is provided with a first chamber capable of containing liquid, the first chamber being in communication with the spray opening; the main arm is provided with a second chamber capable of containing liquid, the second chamber being in communication with the first chamber; and the first end of the temperature-controlled deformation member is located in the first chamber, and the second end of the temperature-controlled deformation member is located in the second chamber.

[0030] In the embodiment of the present application, one end of the temperature control deformation member is located in the first cavity, the other end of the temperature control deformation member is located in the second cavity, and the first cavity and the second cavity are in communication, so that the temperature control deformation member can be in full contact with the liquid, and the temperature of the liquid can be transmitted to the temperature control deformation member by adjusting the temperature of the liquid. The temperature control deformation member can deform under the action of temperature, thereby driving the movable arm to move.

[0031] According to an embodiment of the present application, the movable arm is provided with a first connecting portion, and the first connecting portion is used for fixing the first end of the temperature control deformation member.

[0032] The main arm is provided with a second connecting portion, and the second connecting portion is used for fixing the second end of the temperature control deformation member.

[0033] In the embodiment of the present application, the first connecting portion can be used for fixing the first end of the temperature control deformation member to the movable arm, and the second connecting portion can be used for fixing the second end of the temperature control deformation member to the main arm, so that the first end of the temperature control deformation member can drive the movable arm to move when the temperature control deformation member deforms.

[0034] According to an embodiment of the present application, the movable arm is rotatably connected to the main arm through a rotating shaft.

[0035] The distance between the first connecting portion and the axis of the rotating shaft is less than or equal to the distance between the second connecting portion and the axis of the rotating shaft.

[0036] In the embodiment of the present application, the driving unit can drive the movable arm to rotate around the rotating shaft. By setting the distance between the first connecting portion and the axis of the rotating shaft to be less than or equal to the distance between the second connecting portion and the axis of the rotating shaft, the temperature control deformation member can more flexibly drive the movable arm to rotate when the temperature control deformation member deforms.

[0037] When the first end of the temperature control deformation member is closer to the connecting line of the rotating shaft than the second end of the temperature control deformation member, the first end for driving the movable arm to move is closer to the axis of the rotating shaft, so that the first end can act on the movable arm to drive the movable arm to rotate when the temperature control deformation member deforms slightly, which is beneficial to improve the sensitivity of the movement of the movable arm, so that the temperature control deformation member can drive the movable arm by adjusting the temperature of the liquid to change slightly, which is beneficial to reduce energy consumption.

[0038] According to an embodiment of the present application, the elastic reset member has one end abutting against the main arm and the other end abutting against the movable arm, and the elastic reset member is used for driving the movable arm to move towards the first position.

[0039] In the embodiments of the present application, when the movable arm is between the first position and the second position or at the second position, the elastic return member can generate compression deformation. Since the first chamber of the movable arm is filled with liquid and the movable arm itself has a certain weight, in the case that the liquid flow rate is reduced by the water pump to move the movable arm in the direction of the first position, the force of the elastic potential energy released by the elastic return member can also be used to promote the movement of the movable arm in the direction of the first position, thereby improving the flexibility of the movement of the movable arm between the first direction and the second direction.

[0040] According to an embodiment of the present application, the main arm is provided with a first mounting portion, the movable arm is provided with a second mounting portion opposite to the first mounting portion, one end of the elastic return member abuts against the first mounting portion, and the other end of the elastic return member abuts against the second mounting portion.

[0041] At least one of the first mounting portion and the second mounting portion is provided with a limiting portion for restricting the movement direction of the elastic return member.

[0042] In the embodiments of the present application, the elastic return member can generate elastic deformation between the first mounting portion and the second mounting portion. The limiting portion can be used to prevent the elastic return member from being separated from the first mounting portion and the second mounting portion when the elastic return member generates elastic deformation, thereby improving the movement reliability of the elastic return member.

[0043] According to an embodiment of the present application, the main arm is provided with a second chamber capable of containing liquid, and the second chamber is in communication with the first chamber.

[0044] The spraying device further comprises a flexible connecting member in communication with the first chamber and the second chamber.

[0045] In the embodiments of the present application, the flexible connecting member is provided with a cavity for communicating the first chamber and the second chamber. When the movable arm moves relative to the main arm, the flexible connecting member can generate deformation. The flexible connecting member is not easy to cause large resistance to the movement of the movable arm. Moreover, the flexible connecting member can keep the first chamber and the second chamber in communication, so that the liquid can smoothly enter the first chamber of the movable arm.

[0046] In a second aspect, the present application provides a cleaning device, which comprises:

[0047] A device body having a space capable of containing an article to be cleaned;

[0048] The spraying device of any of the above embodiments can be rotatably connected to the device body, and the spraying device is located at the bottom of the device body.

[0049] In the embodiment of the present application, the spraying device is rotatably connected to the equipment main body, so that the spraying ports on the main arm and the movable arm can be directed to different surfaces of the tableware for washing. In addition, the movable arm in the embodiment of the present application can also move relative to the main arm, so that the spraying direction of the spraying ports on the movable arm can be changed through the movement of the movable arm, so as to expand the range of the spraying ports spraying on the surface of the tableware, and improve the cleaning effect.

[0050] According to one embodiment of the present application, at least one spraying pipe is arranged in the equipment main body, and the driving unit comprises a water pump for adjusting the flow rate of the liquid in the spraying pipe.

[0051] At least part of the water column sprayed by the spraying pipe can be sprayed on the movable arm to drive the movable arm to move between the first position and the second position.

[0052] In the embodiment of the present application, the water pump can be used to adjust the flow rate of the liquid in the movable arm, so as to drive the movable arm to move through the reaction force generated by the liquid spraying effect. In addition, the water column formed by the at least one spraying port in the equipment main body can also be sprayed on the movable arm. The movable arm can move between the first position and the second position under the action of the water column.

[0053] The spraying device provided by the present application has the beneficial effects that the movement of the movable arm relative to the main arm can change the direction of the water column sprayed by the spraying ports on the movable arm, so as to expand the range of the liquid acting on the surface of the tableware. The water column can be sprayed to different position surfaces of the tableware. Through the continuous movement of the movable arm, the surface of the tableware can be washed by the liquid multiple times, avoiding the possibility that part of the area of the tableware is not cleaned, which affects the cleaning effect.

[0054] In addition to the technical problems solved by the above-described embodiments of the present application, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features, the other technical problems solved by the spraying device and the cleaning equipment provided by the embodiments of the present application, the other technical features contained in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific embodiments.

The following description, with reference to the figures, is not meant to limit the scope of the application in any way but is merely meant to illustrate the application with reference to specific embodiments. DETAILED DESCRIPTION

[0079] The exemplary embodiments will be described in detail with reference to the accompanying drawings. In the following description, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the application as detailed in the appended claims. It is apparent that the described embodiments are a part of the application, but not all of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of the application.

[0080] A dishwasher is a kitchen appliance that has the advantages of saving time, labor, strong decontamination ability, water saving, etc. It can be used to automatically clean tableware, cookware and tableware. It uses high-temperature and high-pressure water flow and liquid to remove dirt and food residues on tableware. The dishwasher can save time, free hands, and also achieve higher cleaning standards.

[0081] The dishwasher can include washing, disinfecting, drying, storing tableware, protecting tableware, etc. On the one hand, the cleaning and sterilization of tableware can be realized to improve the hygiene safety of tableware. On the other hand, the tableware can be scientifically cleaned to improve the service life of the tableware.

[0082] The dishwasher can be divided into household dishwasher and commercial dishwasher according to the application scene. The household dishwasher is suitable for family use and can meet the daily cleaning of household tableware. The commercial dishwasher is suitable for restaurants, hotels, etc. It has a large size to realize the one-time washing mode to clean more tableware. The cleaning device provided in the application can be a household dishwasher or a commercial dishwasher, which is not limited in the application.

[0083] The dishwasher includes a device body for accommodating tableware. The device body can be a box structure. The tableware can be placed on the shelf in the device body. The device body is provided with a spraying device. The liquid in the spraying device can be sprayed by the spraying port to form a high-pressure water column. The high-pressure water column can be sprayed to the tableware to wash the tableware.

[0084] In the related art, the water column sprayed by the spray port is correspondingly washed to the same surface area of the tableware in the whole washing mode, and thus, part of the area of the tableware can be washed multiple times, and another part of the area of the tableware can be washed less times or even not washed, thereby causing uneven cleaning of the surface of the tableware, and causing insufficient local cleaning, and further affecting the user experience.

[0085] Based on the above technical problems, the applicant improves the structure of the existing spray device. In the embodiment of the present application, the spray device comprises a movable arm and a main arm. The movable arm can move relative to the main arm under the driving action of the driving unit, so that the direction of the water column sprayed by the spray port on the movable arm changes through the change of the position of the movable arm. Therefore, the water column sprayed by the spray port can be sprayed to different surface areas of the tableware, so as to expand the range of washing the surface of the tableware, so that the surface of the tableware can be washed, thereby improving the uniformity of the washing and washing of the surface of the tableware, reducing the possibility of affecting the cleaning effect caused by insufficient local cleaning, and being beneficial to improving the user experience.

[0086] The spray device 100 and the cleaning equipment 10 provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0087] Referring to Figures 1 to 4 The spray device 100 of the embodiment of the present application comprises a main arm 110, a movable arm 120 and a driving unit.

[0088] The movable arm 120 is rotatably connected to the main arm 110. The movable arm 120 is provided with a spray port 120a. The movable arm 120 moves relative to the main arm 110 between a first position and a second position. When the movable arm 120 is located at the first position, the movable arm 120 and the main arm 110 have a first included angle m. When the movable arm 120 is located at the second position, the movable arm 120 and the main arm 110 have a second included angle n.

[0089] The driving unit is connected to at least one of the main arm 110 and the movable arm 120. The driving unit is used to drive the movable arm 120 to move between the first position and the second position, so as to change the spraying direction of the spray port 120a.

[0090] In the embodiments of the present application, the movable arm 120 is provided with a spray port 120a. The spray port 120a can spray water columns to wash the tableware by the water columns. The driving unit can drive the movable arm 120 to move relative to the main arm 110 between the first position and the second position. When the movable arm 120 is located at the first position and the second position, the included angle between the movable arm 120 and the main arm 110 is different, so that the direction of the water columns sprayed by the spray port 120a of the movable arm 120 is also different when the movable arm 120 is located at the first position and the second position. Therefore, by changing the included angle of the movable arm 120 relative to the main arm 110 through the driving unit, the spray direction of the spray port 120a can be changed. The water columns sprayed by the spray port 120a can act on different surfaces of the tableware to expand the range of the tableware being washed, so that the surfaces of the tableware can be washed by the water columns, which is beneficial to improve the cleaning effect and improve the user experience.

[0091] It should be noted that the first position and the second position of the movable arm 120 refer to the maximum movement range of the movable arm 120. In the washing mode, the movable arm 120 can keep moving between the first position and the second position. For example, the movable arm 120 can reciprocate between the first position and the second position. The movable arm 120 can generate a plurality of different positions between the first position and the second position. When the movable arm 120 is located at different positions, the direction of the water columns sprayed by the spray port 120a is different, so as to expand the range of the tableware surface being washed.

[0092] In the embodiments, the specific structure of the driving unit is not limited. For example, the driving unit can be a mechanical transmission structure. The mechanical transmission structure can drive the movable arm 120 to move. Alternatively, the driving unit can also be a water pump 180. The water pump 180 can provide different flow rates for the liquid in the movable arm 120 to drive the movable arm 120 to move by the flow rate. It is easy to understand that when the flow rate is large, the movable arm 120 can be driven to have a large movement angle, and when the flow rate is small, the movable arm 120 can be driven to have a small movement angle.

[0093] In some examples, a rack 400 for placing tableware can be provided in the device body 200. The spray device 100 can be located below the rack 400. The spray port 120a of the spray device 100 can spray water columns towards the rack 400 located above.

[0094] In some examples, the number of movable arms 120 can be but not limited to one. For example, the movable arm 120 can be two, three or even more. For example Figure 3 and Figure 4 As shown, the number of movable arms 120 can be two. Along the length direction of the main arm 110, the two movable arms 120 can be located at the two ends of the main arm 110 respectively. The two movable arms 120 can rotate relative to the main arm 110 respectively.

[0095] In some examples, the movable arm 120 may be provided with at least one spray port 120a. The axis of the spray port 120a forms an angle with the length direction of the movable arm 120. The direction of the water jet from the spray port 120a is the same as the axis direction of the spray port 120a.

[0096] The angle between the axis of the spray port 120a and the length of the movable arm 120 can be, but is not limited to, 90°. For example, the movable arm 120 can be provided with multiple spray ports 120a. The angles between the axes of at least two spray ports 120a and the length of the movable arm 120 can be different, so that the directions of the water jets from the same movable arm 120 can be different, thereby rinsing different areas of the tableware and improving the cleaning effect.

[0097] In some examples, a plurality of spray ports 120a may be provided on the main arm 110. The directions of the water jets from the spray ports 120a on the main arm 110 may not be completely the same, which is not limited in the present application.

[0098] In some possible implementations, see Figure 3 and Figure 4 As shown, the surface of the main arm 110 facing the object to be cleaned is defined as the first surface 111 , and the surface of the movable arm 120 facing the object to be cleaned is defined as the second surface 121 .

[0099] When the movable arm 120 is in the first position, the second surface 121 forms a first angle m with the first surface 111, which is a straight angle. When the movable arm 120 is in the second position, the movable arm 120 is tilted in the opposite direction of the spray direction of the spray port 120a, and the second surface 121 forms a second angle n with the first surface 111, which is an acute angle.

[0100] In the embodiment of the present application, when the movable arm 120 is in the first position, see Figure 3 As shown, the length direction of the movable arm 120 can be the same as the length direction of the main arm 110. The spray device 100 can be located below the dish rack 400. The end of the movable arm 120 away from the main arm 110 can rotate away from the dish rack 400. In other words, the end of the movable arm 120 away from the main arm 110 rotates downward. This configuration can prevent the movable arm 120 from tilting upward and causing a collision between the movable arm 120 and the dish rack 400.

[0101] refer to Figure 4As shown in the direction, the movable arm 120 located at the left side of the main arm 110 can be rotated counterclockwise from the first position to move to the second position. The movable arm 120 located at the right side of the main arm 110 can be rotated clockwise from the first position to move to the second position.

[0102] When the second included angle n is greater than or equal to a right angle, the movable arm 120 has a too large rotation angle range, and the water column sprayed by the spray port 120a on the movable arm 120 will be sprayed more on the inner wall of the device body 200, thereby causing the water column sprayed on the tableware to be reduced, resulting in the phenomenon that the local area of the tableware is not cleaned. Therefore, by setting the second included angle n to be an acute angle, it can be ensured that sufficient water column can act on the tableware to improve the cleaning effect.

[0103] In some examples, the second included angle n can be, but is not limited to, 10°, 15°, 30°, etc.

[0104] In some implementable manners, referring to Figure 5 As shown, the movable arm 120 of the embodiment of the present application is provided with a first chamber 120b capable of containing liquid. The first chamber 120b is in communication with the spray port 120a.

[0105] The driving unit is used to drive the liquid in the first chamber 120b to flow. The driving unit can adjust the flow rate of the liquid to drive the movable arm 120 to move between the first position and the second position by changing the flow rate of the liquid.

[0106] In the embodiment of the present application, the driving unit can drive the flow rate of the liquid in the first chamber 120b of the movable arm 120. When the flow rate of the liquid in the first chamber 120b is large, the water column sprayed by the spray port 120a can have a large scouring force. On the one hand, the large scouring force can act on the tableware to clean stubborn stains on the tableware, which is beneficial to improve the cleaning effect. On the other hand, the large scouring force can have a reaction force on the movable arm 120, and the movable arm 120 can be subjected to a reverse force while the spray port 120a sprays the water column, so that the movable arm 120 moves in the opposite direction of the spray direction of the spray port 120a.

[0107] In some examples, in the washing mode, the driving unit can change the flow rate of the liquid in the first chamber 120b constantly to make the movable arm 120 always keep a moving state, so that the water column sprayed by the spray port 120a on the movable arm 120 can be sprayed to different areas of the tableware, and the surface of the tableware can be subjected to cleaning and scouring, thereby improving the cleaning effect on the tableware.

[0108] In some examples, the flow rate in the first chamber 120b can be directly adjusted by the driving unit for driving the movable arm 120 to move. Alternatively, the flow in the first chamber 120b can also be adjusted by the driving unit for adjusting the flow rate of the liquid in the first chamber 120b. It is easy to understand that, when the first chamber 120b remains unchanged, the greater the flow of the liquid in the first chamber 120b, the greater the flow rate of the liquid in the first chamber 120b, and thus the greater the angle of the movable arm 120 driven to move.

[0109] In some implementable manners, referring to Figure 1 As shown in the figure, the driving unit of the embodiment of the present application can include a water pump 180. The water pump 180 can be connected in communication with the first chamber 120b through a liquid guide pipe. The water pump 180 is used to adjust the flow rate of the liquid.

[0110] In the embodiment of the present application, the water pump 180 can be directly used to adjust the flow rate of the liquid in the first chamber 120b. The water pump 180 can convert the power of the motor into the power of the liquid, thereby generating the power to drive the liquid to flow. When the washing mode is started, the water pump 180 can be started. The water pump 180 pressurizes the liquid in the first chamber 120b to increase the flow rate of the liquid in the first chamber 120b, thereby providing driving force for the liquid in the first chamber 120b.

[0111] In some examples, the water pump 180 can be a variable frequency water pump 180. The variable frequency water pump 180 can automatically adjust the rotating speed of the water pump 180 for adjusting the flow rate of the liquid in the first chamber 120b, so that the movable arm 120 can be continuously driven to move between the first position and the second position.

[0112] In some implementable manners, referring to Figure 6 As shown in the figure, the driving unit of the embodiment of the present application includes a temperature control deformation piece 130. A first end 131 of the temperature control deformation piece 130 is connected with the movable arm 120. A second end 132 of the temperature control deformation piece 130 is connected with the main arm 110.

[0113] When the temperature of the temperature control deformation piece 130 reaches a first preset temperature, the temperature control deformation piece 130 contracts to drive the movable arm 120 to move in the direction of the second position. When the temperature of the temperature control deformation piece 130 is lower than a second preset temperature, the temperature control deformation piece 130 resets, and the movable arm 120 moves in the direction of the first position.

[0114] In the embodiment of the present application, the temperature control deformation piece 130 can produce deformation under temperature change. Since one end of the temperature control deformation piece 130 is connected with the main arm 110, and the other end is connected with the movable arm 120, when the temperature control deformation piece 130 deforms, the movable arm 120 can be driven to move relative to the main arm 110.

[0115] Specifically, when the temperature of the temperature-controllable deformation member 130 is raised to reach the first preset temperature, the temperature-controllable deformation member 130 can generate a shrinkage deformation. The end of the temperature-controllable deformation member 130 connected with the movable arm 120 can drive the movable arm 120 to deflect towards the main arm 110. In other words, when the temperature is raised, the shrinkage of the temperature-controllable deformation member 130 can drive the movable arm 120 to move from the direction of the first position to the direction of the second position. Correspondingly, when the temperature of the temperature-controllable deformation member 130 is lowered to the second preset temperature, the temperature-controllable deformation member 130 can generate a tensile deformation. The end of the temperature-controllable deformation member 130 connected with the movable arm 120 can drive the movable arm 120 to deflect away from the main arm 110. In other words, when the temperature is lowered, the temperature-controllable deformation member 130 can drive the movable arm 120 to move from the direction of the second position to the direction of the first position. When the washing mode ends, the temperature of the temperature-controllable deformation member 130 gradually cools down, and the temperature-controllable deformation member 130 can drive the movable arm 120 to reset to the direction of the first position.

[0116] Therefore, through the shrinkage and tensile deformation of the temperature-controllable deformation member 130, the movable arm 120 can be driven to overturn relative to the main arm 110 to change the spray direction of the spray opening 120a of the movable arm 120, so that the surface area of the tableware on which the spray is applied can be expanded, and the cleaning uniformity can be improved.

[0117] In some examples, the temperature-controllable deformation member 130 can be, but is not limited to, a memory alloy wire.

[0118] In some implementable manners, referring to Figure 6 As shown in the figure, the main arm 110 of the embodiment of the present application can be provided with a second chamber 110a capable of containing liquid. The second chamber 110a is in communication with the first chamber 120b. The first end 131 of the temperature-controllable deformation member 130 is located in the first chamber 120b. The second end 132 of the temperature-controllable deformation member 130 is located in the second chamber 110a.

[0119] In the embodiment of the present application, since one end of the temperature-controllable deformation member 130 is located in the first chamber 120b, the other end of the temperature-controllable deformation member 130 is located in the second chamber 110a, and the first chamber 120b and the second chamber 110a are in communication, the temperature-controllable deformation member 130 can be in full contact with the liquid, so that the temperature of the liquid can be adjusted to be transmitted to the temperature-controllable deformation member 130. The temperature-controllable deformation member 130 can generate a deformation under the action of the temperature to drive the movable arm 120 to move.

[0120] It should be noted that the temperature control deformation piece 130 has different contraction and stretching length and speed in different temperature environment. Therefore, the temperature of the liquid can be adjusted to change, so that the temperature control deformation piece 130 presents different states, so as to change the angle of the movable arm 120, and expand the range of the spray port 120a spraying to the surface area of the tableware by changing the angle of the movable arm 120.

[0121] In some examples, the spraying device 100 can include a water inlet pipeline 170. The water inlet pipeline 170 can be located at the bottom of the device body 200. The liquid can enter the device body 200 through the water inlet pipeline 170 for cleaning the tableware in the device body 200. The water inlet pipeline 170 can be connected with the main arm 110, so that the liquid entering the water inlet pipeline 170 can enter the second cavity 110a of the main arm 110 and enter the first cavity 120b of the movable arm 120, so that the spray port 120a on the main arm 110 and the spray port 120a on the movable arm 120 can both spray water column to the direction of the tableware.

[0122] In some realizable ways, referring to Figure 6 As shown, the movable arm 120 of the embodiment of the present application is provided with a first connecting part 112. The first connecting part 112 is used for fixing the first end 131 of the temperature control deformation piece 130. The main arm 110 is provided with a second connecting part 122. The second connecting part 122 is used for fixing the second end 132 of the temperature control deformation piece 130.

[0123] In the embodiment of the present application, the first connecting part 112 can be used for fixing the first end 131 of the temperature control deformation piece 130 on the movable arm 120, and the second connecting part 122 can be used for fixing the second end 132 of the temperature control deformation piece 130 on the main arm 110, so that when the temperature control deformation piece 130 generates deformation, the first end 131 of the temperature control deformation piece 130 can drive the movable arm 120 to move.

[0124] In some examples, the first connecting part 112 can protrude from the inner wall of the movable arm 120. The first end 131 of the temperature control deformation piece 130 can be provided with a first hanging ring. The temperature control deformation piece 130 can be hung on the first connecting part 112 through the first hanging ring of the first end 131. Similarly, the second connecting part 122 can protrude from the inner wall of the main arm 110. The second end 132 of the temperature control deformation piece 130 can be provided with a second hanging ring. The temperature control deformation piece 130 can be hung on the second connecting part 122 through the second hanging ring of the second end 132.

[0125] In some examples, when the first hanging ring is hung on the first connecting portion 112 and the second hanging ring is hung on the second connecting portion 122, the first connecting portion 112 and the second connecting portion 122 can be locked by the locking member respectively, so as to avoid the first hanging ring from being detached from the first connecting portion 112 and the second hanging ring from being detached from the second connecting portion 122.

[0129] In some examples, as shown in Figure 7 and Figure 8 In some examples, as shown in

[0130] In the embodiments of the present application, when the movable arm 120 is between the first position and the second position or at the second position, the elastic return member 150 can produce compression deformation. Since the first chamber 120b of the movable arm 120 is filled with liquid and the movable arm 120 itself has a certain weight, in the case that the liquid flow rate is reduced by the water pump 180 to move the movable arm 120 in the direction of the first position, the force of the elastic potential energy released by the elastic return member 150 can also be used to promote the movement of the movable arm 120 in the direction of the first position, thereby improving the flexibility of the movable arm 120 in moving between the first direction and the second direction.

[0131] In some implementable manners, referring to Figure 8 The main arm 110 of the embodiments of the present application can be provided with a first mounting portion 113. The movable arm 120 can be provided with a second mounting portion 123 opposite to the first mounting portion 113. One end of the elastic return member 150 abuts against the first mounting portion 113, and the other end of the elastic return member 150 abuts against the second mounting portion 123.

[0132] At least one of the first mounting portion 113 and the second mounting portion 123 is provided with a limiting portion. The limiting portion is used to constrain the movement direction of the elastic return member 150.

[0133] In the embodiments of the present application, the elastic return member 150 can produce elastic deformation between the first mounting portion 113 and the second mounting portion 123. The limiting portion can be used to prevent the elastic return member 150 from being easily separated from the first mounting portion 113 and the second mounting portion 123 when the elastic return member 150 produces elastic deformation, which is conducive to improving the movement reliability of the elastic return member 150.

[0134] In some examples, the first mounting portion 113 can be provided with a first limiting portion 114. The second mounting portion 123 can be provided with a second limiting portion 124. The first limiting portion 114 can have a space for accommodating at least part of the elastic return member 150. When the elastic return member 150 produces elastic deformation, the elastic return member 150 can be located in the space of the first limiting portion 114. The second limiting portion 124 can protrude from the surface of the second mounting portion 123. At least part of the elastic return member 150 can be sleeved on the second limiting portion 124, so that the elastic return member 150 can not be easily separated from the second limiting portion 124 when the elastic return member 150 produces elastic deformation.

[0135] In some examples, the elastic return member 150 can be, but is not limited to, a spring, a rubber member, etc.

[0136] In some implementable manners, referring to Figure 6 and Figure 8As shown, the spraying device 100 of the embodiment of the present application can further include a flexible connecting piece 160. The flexible connecting piece 160 can be used to connect the first chamber 120b and the second chamber 110a.

[0137] In the embodiment of the present application, the flexible connecting piece 160 is provided with a cavity for connecting the first chamber 120b and the second chamber 110a. When the movable arm 120 moves relative to the main arm 110, the flexible connecting piece 160 can be deformed. The flexible connecting piece 160 is not easy to cause a large resistance to the movement of the movable arm 120. Moreover, the flexible connecting piece 160 can keep the first chamber 120b and the second chamber 110a connected, so that the liquid can smoothly enter the first chamber 120b of the movable arm 120.

[0138] In addition, the flexible connecting piece 160 can have elasticity. When the movable arm 120 moves in the direction from the second position to the first position, the flexible connecting piece 160 can facilitate the reset of the movable arm 120.

[0139] In some examples, the material of the flexible connecting piece 160 can have the characteristics of high elasticity, high temperature resistance, corrosion resistance, etc. The material of the flexible connecting piece 160 can be, but is not limited to, rubber, silicone, etc.

[0140] The embodiment of the present application also provides a cleaning device 10, as shown in Figure 1 As shown, the cleaning device 10 can include a device body 200 and the spraying device 100 in any of the above embodiments.

[0141] The device body 200 has a space for accommodating an article to be cleaned. The article to be cleaned can be tableware, etc. The spraying device 100 can be rotatably connected to the device body 200. The spraying device 100 can be located at the bottom of the device body 200.

[0142] In the embodiment of the present application, the spraying device 100 is rotatably connected to the device body 200, so that the spraying ports 120a on the main arm 110 and the movable arm 120 can be directed to different surfaces of the tableware for washing. In addition, the movable arm 120 in the embodiment of the present application can also move relative to the main arm 110, so that the spraying direction of the spraying ports 120a on the movable arm 120 can be changed by the movement of the movable arm 120, so as to expand the range of the spraying ports 120a spraying on the surface of the tableware, which is conducive to improving the cleaning effect.

[0143] In some examples, the number of the spraying device 100 can be, but is not limited to, one.

[0144] In some realizable ways, the device body 200 of the embodiment of the present application can further be provided with at least one spraying pipe 300. The driving unit can include a water pump 180. The water pump 180 can be used to adjust the flow rate of the liquid in the spraying pipe 300.

[0145] At least part of the water column sprayed by the spray pipe 300 can be sprayed to the movable arm 120 to drive the movable arm 120 to move between the first position and the second position.

[0146] In the embodiments of the present application, the flow rate of the liquid in the movable arm 120 can be adjusted by the water pump 180 to drive the movable arm 120 to move by the reaction force generated by the liquid spraying effect. In addition, the water column formed by at least one spray opening 120a in the device body 200 can also be sprayed on the movable arm 120. The movable arm 120 can move between the first position and the second position under the action of the water column.
