[0058] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] As shown in Figures 1 to 8 , the present application provides a foam local washing device and a washing machine.

[0060] Specifically, in some embodiments of the present application, the foam local washing device comprises a shell 1 with a receiving cavity, a foam washing assembly 2, and a linkage assembly.

[0061] The foam washing assembly 2 has a receiving position and a washing position relative to the shell 1, in the receiving position, the foam washing assembly 2 is received in the receiving cavity of the shell 1, in the washing position, the foam washing assembly 2 is located outside the receiving cavity of the shell 1, as shown in Figure 1 and Figure 2 .

[0062] The linkage assembly is connected with the shell 1 and the foam washing assembly 2, and is used to move the foam washing assembly 2 between the receiving position and the washing position.

[0063] In detail, when using the above-mentioned foam local washing device, the foam washing assembly 2 is moved from the inside of the shell 1 to the outside of the shell 1 through the linkage assembly, which is convenient for local washing or pre-coating of washing reagent. The washing reagent is directly foamed and is not easy to fall off from the clothes, which saves the process of water soaking and rubbing to foam, makes full use of the effective ingredients in the foam, and greatly improves the cleaning, degerming and moisturizing effects.

[0064] After use, the foam washing assembly 2 is moved from the outside of the shell 1 to the inside of the shell 1 through the linkage assembly, so as to avoid occupying a large space by the foam washing assembly 2.

[0065] In a further scheme, the linkage assembly comprises a linkage assembly 3, and the linkage assembly 3 comprises a linkage part 31, a first sliding block 32 and a second sliding block 33.

[0066] The linkage part 31 can rotate around a rotation center; the first sliding block 32 and the second sliding block 33 are respectively arranged at two ends of the linkage part 31 and slide relative to the shell 1.

[0067] The second slider 33 is also connected with a handle part 4, which is connected with the foam cleaning assembly 2. When the handle part 4 is pushed or pulled to move the foam cleaning assembly 2 between the storage position and the cleaning position, the second slider 33 slides relative to the shell 1 and drives the first slider 32 to slide relative to the shell 1 through the connecting rod part 31.

[0068] In detail, the shell 1 is provided with a rotation center, and the connecting rod part 31 forms a pendulum-like movement around the rotation center. Under the action of the connecting rod part 31, the movement trajectories of the first slider 32 and the second slider 33 are parallel. In an embodiment, the movement trajectories of the first slider 32 and the second slider 33 are linear movements. In actual application, the movement trajectories of the first slider 32 and the second slider 33 can be set as arc shapes, etc.

[0069] In use of the above-mentioned foam local cleaning device, a user pulls the handle part 4 to move the foam cleaning assembly 2 from the inside to the outside of the shell 1, and drives the second slider 33 connected with the handle part 4 to slide on the shell 1 in a first direction. At this time, the second slider 33 drives the connecting rod part 31 to rotate around the rotation center and drives the first slider 32 to slide on the shell 1 in a second direction, which is opposite to the first direction.

[0070] After use, the user pushes the handle part 4 to move the foam cleaning assembly 2 from the outside to the inside of the shell 1, and drives the second slider 33 connected with the handle part 4 to slide on the shell 1 in a second direction. At this time, the second slider 33 drives the connecting rod part 31 to rotate around the rotation center and drives the first slider 32 to slide on the shell 1 in a first direction.

[0071] The first direction can be a direction close to the user, and the second direction can be a direction away from the user.

[0072] In an alternative manner, without manual operation of the user, the foam cleaning assembly 2 can be automatically switched between the storage position and the cleaning position, thereby simplifying the operation of the user.

[0073] In detail, the connecting rod assembly 3 further includes a driving unit connected with the rotation center of the connecting rod part 31. The driving unit drives the connecting rod part 31 to rotate around the rotation center, drives the first slider 32 and the second slider 33 to slide on the shell 1, and switches the foam cleaning assembly 2 between the storage position and the cleaning position.

[0074] In a further scheme, the shell 1 is provided with a limiting part limiting the sliding distance of the first slider 32 and the second slider 33, so that the foam cleaning assembly 2 can be pulled out or pushed in by a proper distance.

[0075] In a further aspect, the handle part 4 comprises a base 41 and a connecting wall 43.

[0076] The base 41 has opposite first and second ends, the first end of the base 41 is connected with the second slider 33, and the second end of the base 41 is configured as an operating end, i.e. the end close to the user. The base 41 is arranged below the foam cleaning assembly 2, and a hollow part 42 is arranged at a position corresponding to the foam cleaning assembly 2, so that the water flow of the foam cleaning assembly 2 can flow through.

[0077] The connecting wall 43 also has opposite first and second ends, the first end of the connecting wall 43 is connected with the foam cleaning assembly 2, and the second end of the connecting wall 43 is connected with the first end of the base 41.

[0078] In the above aspect, the user pushes and pulls the base 41 to move the foam cleaning assembly 2 between the storage position and the cleaning position, thereby improving the stability during operation.

[0079] In addition, the hollow part 42 arranged on the base 41 can make the water flow generated by the foam cleaning assembly 2 flow away in time, avoiding the accumulation of foam on the foam cleaning assembly 2 and causing problems such as blockage.

[0080] In some embodiments of the present application, the foam cleaning assembly 2 comprises a water outlet unit 21, a first sensing unit 22, a foam generating unit 23 and a second sensing unit 24.

[0081] In detail, the water outlet unit 21 is used to provide cleaning water during local cleaning; the first sensing unit 22 is used to trigger the water outlet unit 21 to outlet water when clothes are sensed; the foam generating unit 23 is used to provide foam detergent during local cleaning; and the second sensing unit 24 is used to trigger the foam generating unit 23 to generate foam detergent when clothes are sensed.

[0082] In the above aspect, the foam generating unit 23 and the water outlet unit 21 for spraying detergent and water are respectively controlled by sensing devices to determine whether they are started, and in the process of local cleaning, the process of wetting clothes and adding detergent can be alternately performed, thereby improving the cleaning effect on the local position.

[0083] In a further aspect, the foam generating unit 23 and the second sensing unit 24 are arranged in a housing 25, the outlet of the foam generating unit 23 and the sensing end of the second sensing unit 24 are arranged on the bottom wall of the housing 25, and the outlet of the foam generating unit 23 is located away from the sensing end of the second sensing unit 24 relative to the connecting wall 43.

[0084] The above scheme integrates the foam generating unit 23 and the second induction unit 24 in the shell 25, only reserves an outlet for detergent foam on the bottom wall of the shell 25, improves the overall appearance of the device, and improves the user experience.

[0085] Moreover, the outlet of the foam generating unit 23 is arranged at a position away from the connecting wall 43 relative to the induction end of the second induction unit 24, which can avoid the situation that the laundry reaches the outlet of the foam generating unit 23 and starts to generate detergent foam.

[0086] In a further scheme, the water outlet unit 21 and the first induction unit 22 are integrated and arranged below the shell 25 and avoid the outlet of the foam generating unit 23 and the induction end of the second induction unit 24.

[0087] In the above scheme, the water outlet unit 21 and the first induction unit 22 are integrated, which can also improve the overall appearance of the device and improve the user experience.

[0088] Moreover, the components for water outlet and detergent outlet are arranged in an up-down manner, which can reduce the size of the foam local cleaning device in the width direction and facilitate the installation of the foam local cleaning device on structures such as the disc seat 5 of a washing machine.

[0089] The avoiding manner can be, for example, that the size of the water outlet unit 21 and the first induction unit 22 is smaller than that of the foam generating unit 23 and the second induction unit 24.

[0090] In some embodiments of the present application, as shown in Figure 3 and Figure 4 The first sliding groove 11 and the second sliding groove 12 are arranged on the shell 1, and the first sliding block 32 and the second sliding block 33 are arranged in the first sliding groove 11 and the second sliding groove 12, respectively, and slide in the first sliding groove 11 and the second sliding groove 12.

[0120] In detail, the shell 1 is provided with a first sliding groove 11 and a second sliding groove 12; the first sliding block 32 and the second sliding block 33 are respectively arranged in the first sliding groove 11 and the second sliding groove 12 and slide in the first sliding groove 11 and the second sliding groove 12.

[0121] The first sliding groove 11 and the second sliding groove 12 correspond to the first sliding block 32 and the second sliding block 33 one by one. In an embodiment, the movement trajectory of the first sliding block 32 and the second sliding block 33 is linear motion, and in actual application, the movement trajectory of the first sliding block 32 and the second sliding block 33 can be set as arc shape and the like according to needs, and the first sliding block 32 and the second sliding block 33 form the movement trajectory under the limiting action of the first sliding groove 11 and the second sliding groove 12.

[0122] In a further scheme, the connecting rod part 31 includes a first connecting rod 311 and a second connecting rod 312.

[0123] One end of the first connecting rod 311 is connected to the first slider 32, and the other end is slidably connected to the second connecting rod 312. The other end of the second connecting rod 312 is connected to the second slider 33.

[0124] The second connecting rod 312 is connected to a rotating shaft 313 and can rotate around the rotating shaft 313; when the second slider 33 slides in the second groove 12 and drives the second connecting rod 312 to rotate around the rotating shaft 313, the first connecting rod 311 can slide relative to the second connecting rod 312 along the length direction of the second connecting rod 312, and drive the first slider 32 to slide in the first groove 11.

[0125] Specifically, the second connecting rod 312 faces the outer casing 1 and has a connecting rod groove along its length. When the first connecting rod 311 rotates, it can slide relative to the second connecting rod 312 within the range of the connecting rod groove along its length. The second connecting rod 312 also has a second opening along its length. The second slider 33 has a second guide post that cooperates with the second opening. When the connecting rod part 31 rotates, the second guide post, under the action of the second opening, drives the second slider 33 to slide along the second slide groove 12. At the same time, the first connecting rod 311 has a first guide post that cooperates with the second opening. Similarly, when the connecting rod part 31 rotates, the first guide post, under the action of the second opening, drives the first slider 32 to slide along the first slide groove 11. The first connecting rod 311 also has a first opening that cooperates with the rotating shaft 313. When the first connecting rod 311 extends or extends along the length of the second connecting rod 312, the first opening of the first connecting rod 311 also plays a guiding role and prevents the first connecting rod 311 from deviating from the connecting rod groove.

[0126] Furthermore, the outer casing 1 is provided with a first limiting part and a second limiting part, and the second slider 33 is provided with a positioning part. The positioning part cooperates with the first limiting part and the second limiting part respectively to realize the rotational movement of the connecting rod part 31 within a certain range.

[0127] One end of the first slider 32 is rotatably engaged with the first connecting rod 311, and the other end is provided with a mounting part. The mounting part is a cylindrical mounting post with a through hole structure. A rotating part is also provided in conjunction with the mounting part, and the rotating part is connected to the door body 13. A first baffle is provided on the mounting part, and a second baffle is provided on the rotating part. A torsion spring is provided on the outer side of the mounting part, which cooperates with the first baffle and the second baffle. A guide part is provided on the outer shell 1. The torsion spring cooperates with the guide part provided on the inner side of the outer shell 1. The torsion spring and the guide part realize the switching between linear motion and rotational motion. The guide part has an arc-shaped guide structure. After the linear motion is converted into rotational motion, the torsion spring provides a restoring force. This configuration allows the rotational motion of the connecting rod 31 to be converted into the linear motion of the first slider 32, and then the linear motion of the first slider 32 to be converted into the rotational motion of the rotating part, and vice versa.

[0128] When the user manually opens the door 13, the door 13 rotates from a vertical position to a horizontal position, causing the rotating part to rotate and the first slider 32 to slide backward on the outer shell 1. During the sliding process, the first slider 32 causes the first connecting rod 311 and the second connecting rod 312 to rotate around the rotation center, and causes the second slider 33 to slide forward relative to the outer shell 1. At this time, the second slider 33 then causes the foam cleaning component 2 to move from the inside of the outer shell 1 to the outside of the outer shell 1, thereby realizing the movement of the foam cleaning component 2 from the storage position to the cleaning position.

[0129] Conversely, when the user manually pushes the foam cleaning component 2, the foam cleaning component 2 causes the second slider 33 to slide backward on the outer shell 1, causing the second connecting rod 312 to rotate around the rotation center. At the same time, it drives the first connecting rod 311 to rotate around the rotation center, causing the first slider 32 to slide forward relative to the outer shell 1. Simultaneously, it causes the rotating part to rotate, changing the door 13 from a horizontal position to a vertical position and closing the opening of the outer shell 1. Thus, the foam cleaning component 2 moves from the cleaning position to the storage position.

[0130] In some embodiments of the present invention, the linkage assembly 3 further includes a drive unit connected to the linkage portion 31, which drives the linkage portion 31 to rotate about the rotation center. The drive unit may be a motor.

[0131] In a further embodiment, when the door 13 opens the opening of the outer shell 1, the drive unit detects a current signal and drives the connecting rod 31 to rotate around the rotation center in the first direction, so that the foam cleaning assembly 2 automatically moves from the storage position to the cleaning position.

[0132] When the foam cleaning assembly 2 is pushed to move from the cleaning position to the storage position, the drive unit detects the current signal and drives the connecting rod 31 to rotate around the rotation center in the second direction, so that the door 13 closes the opening of the outer shell 1 automatically.

[0133] The above solution can help the foam cleaning component 2 switch between the storage position and the cleaning position, improving the user experience.

[0134] Some embodiments of the present invention also provide a control method for a foam local cleaning device, which is applied to the foam local cleaning device described above.

[0135] The foam spot cleaning device includes a water outlet component and a detergent foam generating component.

[0136] The water outlet assembly is used to provide cleaning water during localized cleaning; the detergent foam generating assembly is used to provide foamed detergent during localized cleaning.

[0137] Preferably, the water outlet assembly includes a water outlet unit 21 and a first sensing unit 22 for controlling whether the water outlet unit 21 is triggered; the detergent foam generating assembly includes a foam generating unit 23 and a second sensing unit 24 for controlling whether the foam generating unit 23 is triggered.

[0138] like Figure 9 and Figure 10 As shown, the control method includes the following steps:

[0139] Determine whether the distance between the sensing end of the water outlet component and the obstruction is less than its trigger distance. If so, control the water outlet component to be in a non-triggering state; otherwise, control the water outlet component to be in a triggering state.

[0140] Determine whether the distance between the sensing end of the detergent foam generating component and the obstruction is less than its trigger distance. If yes, control the detergent foam generating component to be in the triggered state; otherwise, control the detergent foam generating component to be in the non-triggered state.

[0141] Specifically, the foam local cleaning device also includes a housing 1, and the water outlet component and the detergent foam generating component have a storage position and a cleaning position relative to the housing 1, and can switch between the storage position and the cleaning position.

[0142] The water outlet assembly includes the water outlet unit 21 and the first sensing unit 22; the detergent foam generating assembly includes the foam generating unit 23 and the second sensing unit 24.

[0143] In the storage position, the bottom wall of the outer casing 1 serves as a shield for the water outlet assembly and the detergent foam generating assembly; in the cleaning position, the object to be cleaned serves as a shield for the water outlet assembly and the detergent foam generating assembly.

[0144] In existing technologies, sensing units dispense water or detergent when an obstruction is detected. However, the control logic of the first sensing unit 22 of this invention is the opposite of that of existing control logic. This is because the water dispensing component and the detergent foam generating component of this invention have a storage position and a washing position relative to the outer casing 1.

[0145] To minimize the space occupied by the foam spot cleaning device in the washing machine, the outer casing 1 is designed to be as small as possible. Therefore, when stored, the water outlet assembly and the detergent foam generating assembly should be as compact as possible. Since the water outlet assembly is located below the detergent foam generating assembly, the distance between the detergent foam generating assembly and the bottom wall of the outer casing 1 is relatively large when stored; it should be at least greater than the triggering distance of the second sensing unit 24. The distance between the first sensing unit 22 of the water outlet assembly and the bottom wall of the outer casing 1 is relatively small, less than the triggering distance of the first sensing unit 22.

[0146] If the existing control logic is used, the first sensing unit 22 will constantly detect obstructions and continuously discharge water when the storage position is reached.

[0147] To solve the above-mentioned technical problems, the present invention modifies the control logic of the water outlet component to control it in a non-triggered state when the distance between the sensing end of the water outlet component and the obstruction is less than its trigger distance, preventing the water outlet component from being activated and dispensing water; and to control it in a triggered state when the distance between the sensing end of the water outlet component and the obstruction is greater than or equal to its trigger distance, enabling the water outlet component to be activated and dispensing water. The control logic of the detergent foam generating component adopts the existing control logic, that is, to control it in a triggered state when the distance between the sensing end of the detergent foam generating component and the obstruction is less than its trigger distance, enabling the detergent foam generating component to dispense detergent; and to control it in a non-triggered state when the distance between the sensing end of the detergent foam generating component and the obstruction is greater than or equal to its trigger distance, preventing the detergent foam generating component from dispensing detergent.

[0148] The above control method not only solves the technical problem of continuous water output from the water outlet component when the foam local cleaning device is in the storage position due to its compact structure, but also helps to control the water outlet unit 21 and the foam generating unit 23 when the device is in the cleaning position.

[0149] In detail, taking the water outlet assembly and the detergent foam generating assembly in the cleaning position relative to the outer casing 1, with the foam local cleaning device mounted on the washing machine tray 5 as an example, the following explanation is provided. When the user has not yet placed the clothes under the foam local cleaning device, the first sensing unit 22 does not detect any obstruction, the water outlet unit 21 is in the triggered state, and may continuously discharge water or intermittently discharge water at a set frequency. The second sensing unit 24 does not detect any obstruction, the foam generating unit 23 is in the non-triggered state, and the foam generating unit 23 does not discharge detergent foam. When the user places the clothes under the foam local cleaning device, the first sensing unit 22 detects an obstruction, the water outlet unit 21 switches to the non-triggered state and stops discharging water, the second sensing unit 24 detects an obstruction, the foam generating unit 23 is in the triggered state, and the foam generating unit 23 discharges detergent foam.

[0150] Due to the lag in control, when the user places the clothes under the foam spot cleaning device, there is a certain delay between the water outlet unit 21 stopping the water flow and this delay is used to wet the clothes.

[0151] Furthermore, a delay time can be set for the water dispensing unit 21 to transition from a triggered state to a non-triggered state after the first sensing unit 22 senses an obstruction. This delay time ensures that the water dispensing is sufficient to wet the clothes. Similarly, the same delay time can be set for the foam generating unit 23 to transition from a non-triggered state to a triggered state after the second sensing unit 24 senses an obstruction. This allows for seamless integration of water and detergent dispensing.

[0152] In a further embodiment, after controlling the detergent foam generating component to be in the triggered state, the following steps are taken: controlling the detergent foam generating component to start dispensing detergent for a set time and then pausing the start until it is determined again whether the distance between the sensing end of the detergent foam generating component and the obstruction is less than its trigger distance.

[0153] The above solution can prevent continuous liquid discharge caused by accidental triggering.

[0154] It should be noted that a trigger position mark can be set at a suitable location on the washing tub or outer casing 1 of the washing machine so that the user can accurately place the clothes within the trigger range of the first sensing unit 22 and the second sensing unit 24.

[0155] In an alternative implementation, after controlling the water outlet component to be in a triggered state, the process includes: controlling the water outlet component to start discharging water; determining whether the detergent foam generating component has started discharging detergent, and if so, controlling the water outlet component to pause discharging water.

[0156] For certain special user needs, such as not wanting to apply foam detergent while clothes are wet, when placing clothes under the foam spot cleaning device, the user should pay special attention not to place them under the water outlet unit 21. In this case, the first sensing unit 22 will not detect any obstruction and will continue to dispense water. However, the second sensing unit 24 will detect the obstruction and control the foam generating unit 23 to dispense detergent foam. At this time, after the control unit detects that the foam generating unit 23 is in the triggered state and starts dispensing detergent, it should control the water outlet unit 21 to stop dispensing water even if the first sensing unit 22 does not detect any obstruction.

[0157] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
