[0068] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0069] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0070] like Figures 1 to 9 As shown, an exemplary embodiment of the present invention provides a cleaning device 100 , which is used to clean a surface to be cleaned of a cleaning member 200 .

[0071] The part to be cleaned 200 may include but is not limited to a filter, which may be movably arranged in the drying duct of the clothing processing equipment, wherein the filter is detachably arranged in the drying duct, and the surface to be cleaned of the filter can intercept the lint in the drying duct, and when the surface to be cleaned of the filter is cleaned by the cleaning device 100, it will not affect the drying airflow in the drying duct.

[0072] It should be noted that the surface to be cleaned of the cleaning member 200 faces the upstream direction of the drying airflow, that is, the surface to be cleaned faces the direction along the inlet of the drying air duct toward the outlet of the drying air duct.

[0073] The shape of the part to be cleaned 200 may include but is not limited to square or round, and the spray pipe 111 is arranged at the middle position of one side of the surface to be cleaned of the part to be cleaned 200, that is, the projection of the spray pipe 111 on the surface to be cleaned is located at the middle position of the surface to be cleaned.

[0074] In a preferred example, the object to be cleaned 200 is a circular filter screen, and the projection of the spray pipe 111 on the filter screen coincides with one diameter of the circular filter screen.

[0075] See also Figure 1 and Figure 2 As shown, the cleaning device 100 includes a spray assembly 110 and a drive assembly 120 .

[0076] The spray assembly 110 includes a spray pipe 111 disposed opposite to the surface to be cleaned of the object to be cleaned 200. The spray pipe 111 is a hollow cylindrical structure with a dome-shaped end to effectively reduce the volume of the spray assembly 110.

[0077] See also Figure 8 and Figure 9As shown, the spray pipe 111 is provided with a plurality of first spray holes 1111. The plurality of first spray holes 1111 can be spaced apart along the axis of the spray pipe 111 on the sidewall of the spray pipe 111. Alternatively, the plurality of first spray holes 1111 can be divided into two groups and symmetrically arranged on the sidewall of the spray pipe 111. Alternatively, the plurality of first spray holes 1111 can be divided into two groups and staggered in sequence on the sidewall of the spray pipe 111.

[0078] When the plurality of first spray holes 1111 are divided into two symmetrical or staggered groups, the spray directions of the water sprayed in the two groups of first spray holes 1111 are parallel to each other. Alternatively, the spray directions of the water sprayed in the two groups of first spray holes 1111 intersect with each other. Alternatively, the spray directions of the water sprayed in the two groups of first spray holes 1111 are opposite. It should be noted that the spray direction of the water sprayed in one group of first spray holes 1111 is a first direction, and the spray direction of the water sprayed in the other group of first spray holes 1111 is a second direction, and the intersection of the first and second directions is located at a position opposite to the spray direction of the water sprayed.

[0079] The driving assembly 120 is connected to the spray pipe 111, and the driving assembly 120 can drive the spray pipe 111 to rotate, thereby changing the spray direction of the first spray hole 1111. The output end of the driving motor of the driving assembly 120 can be connected to the spray pipe 111, and the driving motor in the driving assembly 120 has a forward and reverse function, so that the spray pipe 111 can rotate along its axial direction through the forward and reverse rotation of the driving motor in the driving assembly 120, thereby causing the spray pipe 111 to rotate forward or reverse within a predetermined angle, thereby achieving effective cleaning of the to-be-cleaned surface of the to-be-cleaned member 200, and also achieving rapid rinsing of the entire to-be-cleaned surface, effectively improving the cleaning effect of the to-be-cleaned surface, ensuring the use of the subsequent to-be-cleaned member 200, thereby extending the use cycle of the to-be-cleaned member 200, and improving the drying efficiency of the subsequent clothing processing equipment.

[0080] As the drive assembly 120 rotates the first spray hole 1111, the spray angle of the first spray hole 1111 changes as its spray direction changes. When the first spray hole 1111 is perpendicular to the surface to be cleaned, the spray angle of the first spray hole 1111 is defined as being at its maximum. Subsequently, as the spray pipe 111 rotates forward or backward, the spray angle of the first spray hole 1111 decreases from the maximum to a certain acute angle, and then from the certain acute angle to the maximum spray angle, and so on. This process is repeated, thereby rapidly rinsing the entire surface to be cleaned of the cleaning object 200.

[0081] like Figure 8 and Figure 9As shown, in some embodiments, a plurality of first spray holes 1111 are arranged along a straight line at intervals on the spray pipe 111. Specifically, the first spray holes 1111 are arranged on the side wall of the spray pipe 111. After spray water is introduced into the spray pipe 111, the first spray holes 1111 are arranged so that the spray water can be sprayed out from the first spray holes 1111 and directly act on the surface to be cleaned, thereby quickly cleaning the lint intercepted on the surface to be cleaned.

[0082] In order to achieve large-area cleaning of the surface to be cleaned and improve the cleaning efficiency at the same time, the first spray hole 1111 is designed to be a trumpet-mouth structure, that is, from the inside of the spray pipe 111 to the outside of the spray pipe 111, the spray diameter of the first spray hole 1111 gradually increases, so that the spray water can be dispersed in a fan shape, thereby effectively cleaning the surface to be cleaned.

[0083] It should be noted that during the rotation of the spray pipe 111, when the first spray hole 1111 is facing the cleaning surface of the cleaning member 200, along the arrangement direction of the first spray holes 1111, the spraying areas of the two adjacent first spray holes 1111 have an overlapping area, wherein the cleaning surface of the cleaning member 200 is located at the intersection of the spray paths of the two adjacent first spray holes 1111.

[0084] like Figure 9 As shown, in some embodiments, the flare angle of the first spray hole 1111 is A, wherein the flare angle A ranges from 40° to 70°. Specifically, the flare angle A of the first spray hole 1111 is 60°. When the flare angle A is set to 60°, the impact force on the cleaning element 200 can be kept within an appropriate range based on the existing water pressure in the laundry processing device, thereby protecting the structure of the cleaning element 200. At the same time, the entire cleaning surface can be quickly cleaned, ensuring a good cleaning effect on the cleaning surface.

[0085] like Figure 8 and Figure 9 As shown, in some embodiments, one end of the spray pipe 111 is a closed end, and the closed end is provided with a second spray hole 1112. When the first spray hole 1111 is facing the surface to be cleaned, the second spray hole 1112 is relatively higher than the first spray hole 1111.

[0086] It should be noted that the closed end of the spray pipe 111 is the end away from the connection position between the driving assembly 120 and the spray pipe 111.

[0087] Among them, when the first spray hole 1111 is facing the surface to be cleaned, the upper edge of the second spray hole 1112 is set to be inclined upward, while the lower edge of the second spray hole 1112 is set to be inclined downward, and the inclination angles of the upper edge and the lower edge of the second spray hole 1112 are different.

[0088] Based on this, the length of the spray pipe 111 can be set to be shorter than the diameter of the filter screen. When the spray water in the spray pipe 111 is sprayed out from the second spray hole 1112, the structural design of the second spray hole 1112 can be used to effectively flush the surface to be cleaned in the direction of the side wall end of the spray pipe 111, thereby reducing the spatial size of the cleaning device 100. That is, the entire surface to be cleaned of the entire part to be cleaned 200 can be effectively flushed through a cleaning device 100 of a smaller volume.

[0089] like Figure 1 and Figure 2 As shown, in some embodiments, the object to be cleaned 200 is fixed to the mounting frame 130. The closed end of the spray pipe 111 passes through the side wall of the mounting frame 130 and extends into the interior of the mounting frame 130. In addition, the spray pipe 111 is rotatably arranged relative to the side wall of the mounting frame 130. In other words, the spray pipe 111 can rotate on the mounting frame 130.

[0090] Among them, the mounting rack 130 can be installed on the clothing processing equipment, specifically, it can be set in the drying duct of the clothing processing equipment. The mounting rack 130 is used to effectively fix the cleaning part 200 so that the cleaning surface of the cleaning part 200 can be quickly rinsed using the spray pipe 111.

[0091] In this example, the mounting bracket 130 can be used to effectively fix the cleaning component 200 (i.e., the filter screen). At the same time, the spray pipe 111 is rotated and set on the side wall of the mounting bracket 130. The driving component 120 drives the spray pipe 111 to rotate, and then the first spray hole 1111 and the second spray hole 1112 set on the spray pipe 111 are used to quickly clean the entire surface to be cleaned, thereby effectively ensuring the cleaning effect of the surface to be cleaned.

[0092] It should be noted that the driving assembly 120 can be installed on the mounting bracket 130, or the driving assembly 120 can be fixed on the clothes processing drum.

[0093] like Figure 3 and Figure 4 As shown, in some embodiments, in order to improve the sealing of the spray pipe 111 during the rotation process and prevent the spray water from leaking from the connection position between the spray pipe 111 and the mounting frame 130, a seal 140 is provided between the spray pipe 111 and the side wall of the mounting frame 130.

[0094] The inner wall of the sealing member 140 is sleeved on the outer wall of the spray pipe 111, and the outer wall of the sealing member 140 is inserted into the side wall of the mounting frame 130. The sealing member 140 and the side wall of the mounting frame 130 are in an interference fit.

[0095] The seal 140 may include, but is not limited to, a rubber stopper.

[0096] like Figure 3 and Figure 4 As shown, in some embodiments, a rotating member 150 is provided on the outer peripheral wall of the spray pipe 111. The rotating member 150 is closer to the driving assembly 120 than the sealing member 140, and the rotating member 150 is embedded in the side wall of the mounting frame 130.

[0097] The rotating member 150 may include, but is not limited to, a rotating bearing. The rotating bearing can achieve the rotation of the spray pipe 111 and make the rotation of the spray pipe 111 smoother. It should be noted that the rotating member 150 is disposed on the end of the spray pipe 111 away from the closed end.

[0098] like Figures 1 to 7 As shown, in some embodiments, the driving assembly 120 includes a driving motor 121, a driving gear 122, and a driven gear 123. The driving motor 121 may include, but is not limited to, a servo motor or a DC motor with forward and reverse rotation functions.

[0099] The output end of the driving motor 121 is connected to the driving gear 122. The driven gear 123 is sleeved on the spray pipe 111 and fixedly connected to the spray pipe 111, wherein a semi-annular gear segment 123a is provided on the outer circumference of the driven gear 123.

[0100] The driving gear 122 is meshed with the semi-annular gear segment 123a on the driven gear 123 for transmission connection, so that the spray pipe 111 rotates forward or reverse within a predetermined angle through the forward rotation or reverse rotation of the driving motor 121, thereby changing the spray direction of the first spray hole.

[0101] It should be noted that, since the gear segment 123 a is designed as a semi-annular structure, limiting portions are formed at both ends of the gear segment 123 a.

[0102] When the drive motor 121 drives the drive gear 122 to rotate forward and contacts the stopper on one side of the gear segment 123a, it indicates that the rotation angle of the spray pipe 111 has reached the maximum rotation angle. If the drive motor 121 rotates further, the actual power of the drive motor 121 will exceed its preset power. At this time, the control system of the laundry processing device can control the drive motor 121 to switch from forward rotation to reverse rotation, thereby allowing the spray pipe 111 to rotate in the reverse direction. After the drive gear 122 contacts the stopper on the other side of the gear segment 123a, the drive motor 121 switches from reverse rotation to forward rotation. Repeating this process N times can quickly and effectively rinse the cleaning surface of the cleaning element 200, ensuring a clean surface.

[0103] In one example, the predetermined angle of the spray pipe 111 ranges from -90° to +90°, wherein the 0° position is the position where the first spray hole 1111 is arranged relative to the surface to be cleaned.

[0104] like Figure 3 and Figure 4 As shown, in some embodiments, a fixing member 160 is provided on the spray pipe 111, and the fixing member 160 is located between the driven gear 123 and the rotating member 150. The fixing member 160 can be used to fix the spray pipe 111 on the clothes processing tub to prevent the spray pipe 111 from falling off from the clothes processing tub.

[0105] The fixing member 160 is a pressure cover that presses the rotating member 150 to fix the rotating member 150 on the clothes processing drum. It should be noted that one end of the spray pipe 111 passes through the rotating member 150 and the pressure cover and then fixes the driven gear 123.

[0106] In some embodiments, as the spray pipe 111 rotates, the spray angle of the first spray hole 1111 changes.

[0107] The first spray hole 1111 is defined as having a first position, a second position, and a third position during the rotation of the spray pipe 111. When the first spray hole 1111 is in the first position, the first spray hole 1111 is perpendicular to the surface to be cleaned, and the second and third positions are located on either side of the first position.

[0108] When the driving motor 121 drives the spray pipe 111 to rotate, the first spray hole 1111 rotates from the second position to the first position, or from the third position to the first position, and the spray angle of the first spray hole 1111 gradually increases.

[0109] As the spray angle of the first spray hole 1111 gradually increases, the spray pressure in the spray pipe 111 decreases as the spray angle of the first spray hole 1111 increases. In other words, when the first spray hole 1111 is facing the surface to be cleaned, the spray pressure in the spray pipe 111 is relatively low, which can reduce the frontal impact force of the spray water on the surface to be cleaned, thereby ensuring and extending the service life of the object to be cleaned 200.

[0110] When the first spray hole 1111 rotates from the first position to the second position or the third position, the spray angle of the first spray hole 1111 gradually decreases.

[0111] As the spray angle of the first spray hole 1111 gradually decreases, the spray pressure within the spray pipe 111 increases as the spray angle of the first spray hole 1111 decreases. In other words, when the first spray hole 1111 rotates toward the second or third position, the higher spray pressure can achieve rapid cleaning at a greater distance from the surface to be cleaned, reducing cleaning time. Furthermore, when the first spray hole 1111 rotates toward the second or third position, the impact force of the spray water can be used to clean accumulated lint on the surface to be cleaned at a certain angle, thereby improving cleaning efficiency.

[0112] like Figure 1 and Figure 2 As shown, an exemplary embodiment of the present invention provides a drying duct 300, which is provided with a mounting frame 130, and a to-be-cleaned object 200 is movably mounted on the mounting frame 130, wherein the to-be-cleaned object 200 is used to intercept lint flowing in the drying duct. The to-be-cleaned object 200 may include, but is not limited to, a filter.

[0113] The cleaning device 100 of any of the above-described embodiments is mounted on a mounting frame 130 and can be used to clean the surface of the filter to be cleaned. The inlet end of the spray pipe 111 in the cleaning device 100 can be connected to an external water inlet pipe, for example, to a indoor tap water pipe. Alternatively, the inlet end of the spray pipe 111 can be connected to a water inlet pipe within a laundry treatment device.

[0114] The spray pipe 111 is driven to rotate by the driving component 120, and then the multiple first spray holes 1111 and second spray holes 1112 are used to quickly flush the surface to be cleaned of the filter screen to ensure the cleaning effect of the surface to be cleaned and avoid the accumulated hair from affecting the drying airflow in the drying duct.

[0115] like Figure 1 and Figure 2 As shown, an exemplary embodiment of the present invention provides a laundry processing drum 400 , on which the drying air duct 300 of the above embodiment is provided.

[0116] The inlet end of the drying air duct 300 is communicated with the outlet of the laundry processing tub 400 , and the outlet end of the drying air duct 300 is communicated with the inlet of the laundry processing tub 400 .

[0117] The drying duct 300 may include a drying fan, which is a variable frequency fan, and a drying module, which is configured to dehumidify and heat the hot and humid air drawn from the laundry treatment drum to form a drying airflow, thereby drying the bound water in the laundry.

[0118] The drying module can be directly fixed in the drying air duct 300, or fixed in the drying air duct by other fasteners such as screws, etc. The drying module can be arranged at a position close to the air outlet end of the drying air duct.

[0119] It should be noted that the drying module may include but is not limited to an electric heating wire or a PTC (Positive Temperature Coefficient, positive temperature coefficient thermistor) heater or other elements capable of heating air.

[0120] The drying fan is located upstream of the drying module, along the direction of the drying airflow. The rotation of the drying fan not only guides the hot and humid air drawn from the laundry processing drum 400 into the drying module to form a drying airflow, but also drives the drying airflow into the laundry processing drum 400, providing an appropriate amount of drying air to meet the drying airflow requirements of the laundry processing drum 400. Alternatively, during the drying process of laundry or during cooling of the laundry processing drum 400 at the end of the drying process, an appropriate airflow is provided to meet the drying requirements of the laundry.

[0121] The drying fan adopts the structure in the prior art, or the drying fan can directly use an induced draft fan, an axial flow fan, etc.

[0122] On the other hand, one drying air duct 300 may be connected to two or more laundry processing drums 400 , that is, two or more laundry processing drums 400 share one drying air duct 300 .

[0123] like Figure 1 and Figure 2 As shown, an exemplary embodiment of the present invention provides a laundry processing device 10, which includes a laundry processing drum 400 of the above embodiment. A water inlet pipe 20 is provided in the laundry processing device 10, and the water inlet pipe 20 is connected to the spray pipe 111 in the cleaning device 100.

[0124] The clothes processing device 10 may include but is not limited to a washing machine, which may include but is not limited to a washing and care machine, a washing and drying machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with a drying or washing and care function, etc. Of course, the washing machine may also be other types of fully automatic washing machines.

[0125] like Figure 10 As shown, an exemplary embodiment of the present invention provides a cleaning control method for a clothes processing device, which is applied to the clothes processing device 10 of the above embodiment. The cleaning control method for the clothes processing device includes the following steps:

[0126] Step S100: in response to a cleaning start instruction of the clothes processing device, controlling the water inlet pipe to deliver spray water into the spray pipe.

[0127] Step S200: controlling the driving motor to rotate to drive the spray pipe to rotate.

[0128] Step S300: In response to a cleaning stop instruction of the clothes treating apparatus, the driving motor is controlled to stop rotating.

[0129] In step S100, when the control system receives a cleaning instruction from the user or the control system independently determines that the part to be cleaned 200, i.e., the filter screen, needs to be cleaned, the control system controls the control valve on the water inlet pipe 20 to deliver spray water to the spray pipe through the water inlet pipe.

[0130] It should be noted that the control system of the clothing processing equipment can adopt the control device in the existing technology, as long as the control device can control the various startup functions of the clothing processing equipment, and the specific structural type and specific control logic of the control device will not be repeated here.

[0131] In step S200, the control system controls the drive motor 121 to rotate, thereby driving the spray pipe 111. The drive motor 121 is first controlled to rotate at a fixed speed, driving the spray pipe 111 to rotate at a stable rotational pace. The fixed speed may be factory-set for the clothing processing device, user-set, or flexibly set by the control system based on the degree of filter contamination and blockage, and is not specifically limited here.

[0132] When the first actual power W1 of the driving motor 121 is greater than or equal to the set power W, that is, W1>W, at this time, one tooth of the driving gear 122 contacts a limiting part of the gear segment 123a of the driven gear 123, controlling the driving motor 121 to rotate in the reverse direction at a fixed speed to drive the spray pipe 111 to rotate in the reverse direction.

[0133] During the reverse rotation of the drive motor 121, when the second time power W2 of the drive motor 121 is greater than or equal to the set power W, that is, W2>W, at this time, one tooth of the drive gear 122 contacts another limiting part of the gear segment 123a of the driven gear 123, controlling the drive motor 121 to rotate forward at a fixed speed to drive the spray pipe 111 to rotate forward.

[0134] Repeat the above-mentioned forward and reverse rotations of the driving motor N times, where N is an integer greater than or equal to 2, to complete the cleaning process of the surface to be cleaned.

[0135] It should be noted that, when the driving motor 121 drives the spray pipe 111 to rotate forward or reverse, the spray angle of the first spray hole 1111 will change.

[0136] The first spray hole 1111 is defined as having a first position, a second position, and a third position during the rotation of the spray pipe 111. When the first spray hole 1111 is in the first position, the first spray hole 1111 is perpendicular to the surface to be cleaned, and the second and third positions are located on either side of the first position.

[0137] When the driving motor 121 drives the spray pipe 111 to rotate, the first spray hole 1111 rotates from the second position to the first position, or from the third position to the first position, and the spray angle of the first spray hole 1111 gradually increases.

[0138] As the spray angle of the first spray hole 1111 gradually increases, the spray pressure in the spray pipe 111 decreases as the spray angle of the first spray hole 1111 increases. In other words, when the first spray hole 1111 is facing the surface to be cleaned, the spray pressure in the spray pipe 111 is relatively low, which can reduce the frontal impact force of the spray water on the surface to be cleaned, thereby ensuring and extending the service life of the object to be cleaned 200.

[0139] When the first spray hole 1111 rotates from the first position to the second position or the third position, the spray angle of the first spray hole 1111 gradually decreases.

[0140] As the spray angle of the first spray hole 1111 gradually decreases, the spray pressure within the spray pipe 111 increases as the spray angle of the first spray hole 1111 decreases. In other words, when the first spray hole 1111 rotates toward the second or third position, the higher spray pressure can achieve rapid cleaning at a greater distance from the surface to be cleaned, reducing cleaning time. Furthermore, when the first spray hole 1111 rotates toward the second or third position, the impact force of the spray water can be used to clean accumulated lint on the surface to be cleaned at a certain angle, thereby improving cleaning efficiency.

[0141] In step S300, when the control system receives the cleaning stop instruction, the control system controls the spray pipe 111 to stop the spraying action, and at the same time, controls the drive motor 121 to continue to drive the spray pipe 111 to rotate. When the actual power of the drive motor 121 is greater than or equal to the preset power, the drive motor 121 is controlled to rotate clockwise at the same fixed speed. After the drive motor 121 rotates for the preset time T, the drive motor 121 is controlled to stop rotating so that the spray pipe 111 is reset, that is, the first spray hole 1111 is set at the specified position, and the cleaning process of the cleaning part 200 is completed.

[0142] It should be noted that the value of the preset rotation time T of the driving motor 121 can be flexibly set according to the specifications or model of the clothing processing equipment 10, or can be flexibly set according to the cross-sectional size of the spray pipe 111 and the diameter size of the part to be cleaned 200, i.e., the filter screen, or can also be flexibly set according to the specifications and dimensions of the clothing processing drum 400 and the drying duct 300, and no specific limitation is made here.
