Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes processing, and particularly relates to a foam partial cleaning device and a washing machine. BACKGROUND

[0002] A washing machine is a machine for cleaning laundry by mechanical force generated by electricity. For shirts and other similar clothes, the collar and the cuff are generally more soiled than other positions. However, the washing effect of the existing washing machine on the local positions such as the collar and the cuff is poor during the washing process.

[0003] In the prior art, an ultrasonic washing device is often additionally arranged on the washing machine to achieve the purpose.

[0004] For example, a washing machine with a local ultrasonic washing device is disclosed in Chinese Patent No. CN200520069251.1, which comprises a washing machine body and an ultrasonic washing device. The ultrasonic washing device comprises an ultrasonic generator, a transducer, a device box, and a transducer base. The ultrasonic generator is installed in the computer board and connected with the transducer. The transducer is installed on the base in the device box and pressed by the cover plate. The ultrasonic washing device is fixed by a positioning support and installed at the rear of the washing machine workbench through the positioning support.

[0005] Chinese Patent No. CN2017101131757 discloses a clothes local cleaning structure and a washing machine. The clothes local cleaning structure is detachably arranged on the washing machine disc seat and connected with the washing machine water inlet and the detergent box. The clothes local cleaning structure comprises a pressing plate and a supporting plate. The pressing plate comprises an ultrasonic transducer, and the supporting plate comprises a water inlet cavity. The shape of the pressing plate is matched with the supporting plate. After being pressed towards the supporting plate, the pressing plate and the supporting plate form a gap for clamping the local clothes to be washed and ultrasonically cleaning the local clothes to be washed.

[0006] The above scheme solves the problem that the washing machine cannot clean the local positions with high soiling degree to a certain extent.

[0057] As shown in Figures 1 to 8 , the present application provides a foam local washing device and a washing machine.

[0058] Specifically, in some embodiments of the present application, the foam local washing device comprises a housing 1 with a receiving cavity, a foam washing assembly 2 and a linkage assembly 3.

[0060] The linkage assembly 3 is connected with the housing 1 and the foam washing assembly 2, for moving the foam washing assembly 2 between the receiving position and the washing position.

[0061] In detail, when using the above-mentioned foam local washing device, the foam washing assembly 2 is moved from the inside of the housing 1 to the outside of the housing 1 by the linkage assembly 3, which is convenient for local washing or pre-coating of washing agent, the washing agent is directly foamed, not easy to fall off from the clothes, the process of soaking and rubbing to foam is saved, the effective ingredients in the foam are fully utilized, and the cleaning, degerming and moisturizing effects are greatly improved.

[0062] After use, the foam washing assembly 2 is moved from the outside of the housing 1 to the inside of the housing 1 by the linkage assembly 3, so as to avoid occupying a large space by the foam washing assembly 2.

[0063] In further solutions, the linkage assembly 3 comprises a linkage part 31, a first sliding block 32 and a second sliding block 33.

[0064] 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 housing 1.

[0065] The second sliding block 33 is further connected with a handle part 4, the handle part 4 is connected with the foam washing assembly 2, when the foam washing assembly 2 is moved between the receiving position and the washing position by pushing and pulling the handle part 4, the second sliding block 33 slides relative to the housing 1 and drives the first sliding block 32 to slide relative to the housing 1 through the linkage part 31.

[0066] In detail, the shell 1 is provided with a rotation center, and the link part 31 rotates around the rotation center to form a pendulum-like movement. Under the action of the link part 31, the first sliding block 32 and the second sliding block 33 generate a movement track parallel to each other. In an embodiment, the movement track of the first sliding block 32 and the second sliding block 33 is a linear movement. In actual application, the movement track of the first sliding block 32 and the second sliding block 33 can be set as an arc shape or the like according to needs.

[0067] In use of the above-mentioned foam local cleaning device, the user pulls the handle part 4 to move the foam cleaning assembly 2 from the inside to the outside of the shell 1, and at the same time drives the second sliding block 33 connected with the handle part 4 to slide in a first direction on the shell 1.

The driving unit drives the link part 31 to rotate around the rotation center, drives the first sliding block 32 and the second sliding block 33 to slide on the shell 1, and switches the foam cleaning assembly 2 between the storage position and the cleaning position.

[0072] In a further scheme, the shell 1 is provided with a limiting part limiting the sliding distance of the first sliding block 32 and the second sliding block 33, so that the foam cleaning assembly 2 can be pulled out or pushed in by a proper distance.

[0073] In a further scheme, the handle part 4 comprises a base 41 and a connecting wall 43.

[0074] 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. an 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 flows through.

[0075] 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.

[0076] In the above scheme, 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.

[0077] In addition, the hollow part 42 is arranged on the base 41, which can make the water flow generated by the foam cleaning assembly 2 flow away in time, avoid the accumulation of foam on the foam cleaning assembly 2, and cause problems such as blockage.

[0078] In some embodiments of the present application, the foam cleaning assembly 2 includes a water outlet unit 21, a first sensing unit 22, a foam generating unit 23, and a second sensing unit 24.

[0079] 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-shaped detergent during local cleaning; and the second sensing unit 24 is used to trigger the foam generating unit 23 to generate foam-shaped detergent when clothes are sensed.

[0080] In the above scheme, the foam generating unit 23 and the water outlet unit 21 for spraying detergent and water are respectively controlled by sensing devices to start or not, 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] 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.

[0084] 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.

[0119] The second connecting rod 312 is connected with a rotating shaft 313 and can rotate around the rotating shaft 313; when the second sliding block 33 slides in the second sliding groove 12 to drive 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 the first sliding block 32 is driven to slide in the first sliding groove 11.

[0120] Specifically, the second connecting rod 312 is provided with a connecting rod groove on the side of the shell 1 in the length direction of the second connecting rod 312, and the first connecting rod 311 can extend into or out of the second connecting rod 312 in the length direction of the second connecting rod 312 within the range of the connecting rod groove to realize the sliding of the first connecting rod 311 relative to the second connecting rod 312. The second connecting rod 312 is also provided with a second opening in the length direction thereof, and the second sliding block 33 is provided with a second guide column matched with the second opening. When the connecting rod part 31 rotates, the second guide column drives the second sliding block 33 to slide along the second sliding groove 12 under the action of the second opening. Meanwhile, the first connecting rod 311 is provided with a first guide column matched with the second opening. Similarly, when the connecting rod part 31 rotates, the first guide column drives the first sliding block 32 to slide along the first sliding groove 11 under the action of the second opening. The first connecting rod 311 is also provided with a first opening matched with the rotating shaft 313. When the first connecting rod 311 extends into or out of the second connecting rod 312 in the length direction of the second connecting rod 312, the first opening of the first connecting rod 311 also plays a guiding role and also avoids the deviation of the first connecting rod 311 from the connecting rod groove.

[0121] Further, the shell 1 is provided with a first limiting part and a second limiting part, and the second sliding block 33 is provided with a positioning part matched with the first limiting part and the second limiting part respectively to realize the rotary movement of the connecting rod part 31 within a certain range.

[0122] One end of the first sliding block 32 is rotationally matched with the first connecting rod 311, and the other end is provided with a mounting part in the form of a cylindrical mounting column with a through hole structure. A rotating part matched with the mounting part is also provided, and the rotating part is connected with the door body 13. The mounting part is provided with a first baffle, and the rotating part is provided with a second baffle. The outer side of the mounting part is provided with a torsional spring matched with the first baffle and the second baffle. The shell 1 is provided with a guide part matched with the torsional spring provided on the inner side of the shell 1. The torsional spring and the guide part realize the switching between the linear motion and the rotary motion. The guide part is in the form of an arc-shaped guide structure. The torsional spring provides a restoring force after the linear motion is converted into the rotary motion. This arrangement converts the rotary motion of the connecting rod part 31 into the linear motion of the first sliding block 32, and then converts the linear motion of the first sliding block 32 into the rotary motion of the rotating part, and vice versa.

[0123] When the user manually opens the door body 13, the door body 13 rotates and drives the first sliding block 32 to slide backward on the shell 1 in the process of converting from the vertical position to the horizontal position. The first sliding block 32 drives the first connecting rod 311 and the second connecting rod 312 to rotate around the rotating center in the process of sliding, and drives the second sliding block 33 to slide forward relative to the shell 1. At this time, the second sliding block 33 drives the foam cleaning assembly 2 to move from the inside of the shell 1 to the outside of the shell 1, thereby realizing the movement of the foam cleaning assembly 2 from the storage position to the cleaning position.

[0124] Conversely, when the user manually pushes the foam cleaning assembly 2, the foam cleaning assembly 2 drives the second sliding block 33 to slide backward on the shell 1, so that the second connecting rod 312 rotates around the rotation center, and at the same time, the first connecting rod 311 is also driven to rotate around the rotation center, thereby driving the first sliding block 32 to slide forward relative to the shell 1, and at the same time, the rotating part is driven to rotate, so that the door body 13 is converted from the horizontal position to the vertical position to close the opening of the shell 1, thereby realizing the movement of the foam cleaning assembly 2 from the cleaning position to the storage position.

[0125] In some embodiments of the present application, the connecting rod assembly 3 further comprises a driving part connected with the connecting rod part 31 to drive the connecting rod part 31 to rotate around the rotation center. The driving part can be an electric motor.

[0126] In a further scheme, when the door body 13 opens the opening of the shell 1, the driving part drives the connecting rod part 31 to rotate around the rotation center in the first direction after detecting the current signal, so that the foam cleaning assembly 2 is automatically moved from the storage position to the cleaning position.

[0127] When the foam cleaning assembly 2 is pushed to move from the cleaning position to the storage position, the driving part drives the connecting rod part 31 to rotate around the rotation center in the second direction after detecting the current signal, so that the door body 13 is automatically closed to close the opening of the shell 1.

[0128] The above scheme can assist the foam cleaning assembly 2 to switch between the storage position and the cleaning position, thereby improving the user experience.

[0129] In some embodiments of the present application, a control method of a foam local cleaning device is also provided, which is applied to the foam local cleaning device.

[0130] The foam local cleaning device comprises a water outlet assembly and a detergent foam generating assembly.

[0131] The water outlet assembly is used to provide cleaning water during local cleaning, and the detergent foam generating assembly is used to provide foam-shaped detergent during local cleaning.

[0132] Preferably, the water outlet assembly comprises a water outlet unit 21 and a first sensing unit 22 for controlling whether the water outlet unit 21 is triggered, and the detergent foam generating assembly comprises a foam generating unit 23 and a second sensing unit 24 for controlling whether the foam generating unit 23 is triggered.

[0133] As shown in Figure 9 and Figure 10 The control method comprises the following steps:

[0134] determining whether the distance between the sensing end of the water outlet assembly and the shelter is less than the triggering distance thereof, if yes, controlling the water outlet assembly to be in the non-triggering state, if no, controlling the water outlet assembly to be in the triggering state;

[0135] determining whether the distance between the sensing end of the detergent foam generating assembly and the shelter is less than the triggering distance thereof, if yes, controlling the detergent foam generating assembly to be in the triggering state, if no, controlling the detergent foam generating assembly to be in the non-triggering state.

[0136] Specifically, the foam partial cleaning device further comprises a shell 1, the water outlet assembly and the detergent foam generating assembly have a storage position and a cleaning position relative to the shell 1, and switch between the storage position and the cleaning position.

[0137] The water outlet assembly comprises the water outlet unit 21 and the first sensing unit 22, and the detergent foam generating assembly comprises the foam generating unit 23 and the second sensing unit 24.

[0138] In the storage position, the bottom wall of the shell 1 constitutes the shelter of the water outlet assembly and the detergent foam generating assembly; in the cleaning position, the object to be cleaned constitutes the shelter of the water outlet assembly and the detergent foam generating assembly.

[0139] The sensing units in the prior art are all to water or detergent when sensing the shelter, but the control logic of the above-mentioned first sensing unit 22 of the present application is opposite to the existing control logic. This is because the water outlet assembly and the detergent foam generating assembly of the present application have a storage position and a cleaning position relative to the shell 1.

[0140] In order to minimize the space occupied by the foam partial cleaning device in the washing machine, the shell 1 is designed to be as small as possible, so that in the storage position, the water outlet assembly and the detergent foam generating assembly should be as compact as possible. The water outlet assembly is arranged below the detergent foam generating assembly, which results in that in the storage position, the distance between the detergent foam generating assembly and the bottom wall of the shell 1 is large, which should be at least greater than the triggering distance of the second sensing unit 24, and the distance between the first sensing unit 22 of the water outlet assembly and the bottom wall of the shell 1 is small, which is less than the triggering distance of the first sensing unit 22.

[0141] If the existing control logic is adopted, the first sensing unit 22 will always sense the shelter and continuously water in the storage position.

[0142] To solve the above technical problems, the control logic of the water outlet assembly is modified to determine that when the sensing end of the water outlet assembly is less than the trigger distance from the blocking object, the water outlet assembly is controlled to be in a non-trigger state, and the water outlet assembly cannot be started to outlet water; and when the sensing end of the water outlet assembly is greater than or equal to the trigger distance from the blocking object, the water outlet assembly is controlled to be in a trigger state, and the water outlet assembly can be started to outlet water. The control logic of the detergent foam generating assembly is the existing control logic, that is, when the sensing end of the detergent foam generating assembly is less than the trigger distance from the blocking object, the detergent foam generating assembly is controlled to be in a trigger state, and the detergent foam generating assembly can be triggered to outlet detergent; and when the sensing end of the detergent foam generating assembly is greater than or equal to the trigger distance from the blocking object, the detergent foam generating assembly is controlled to be in a non-trigger state, and the detergent foam generating assembly cannot be triggered to outlet detergent.

[0143] The above control method not only solves the technical problem that the water outlet assembly continuously outlets water when in the storage position due to the compact structure of the foam partial cleaning device, but also is beneficial to controlling the water outlet unit 21 and the foam generating unit 23 when in the cleaning position.

[0144] In detail, taking the foam partial cleaning device arranged on the disc seat 5 of the washing machine as an example, when the user has not placed clothes under the foam partial cleaning device, the first sensing unit 22 cannot sense the blocking object, the water outlet unit 21 is in a trigger state, and can continuously outlet water or intermittently outlet water according to the set frequency; the second sensing unit 24 cannot sense the blocking object, and the foam generating unit 23 is in a non-trigger state, and the foam generating unit 23 does not outlet detergent foam. When the user places clothes under the foam partial cleaning device, the first sensing unit 22 senses the blocking object, and the water outlet unit 21 changes to a non-trigger state and does not outlet water; the second sensing unit 24 senses the blocking object, and the foam generating unit 23 is in a trigger state, and the foam generating unit 23 outlets detergent foam.

[0145] Due to the hysteresis of the control, when the user places clothes under the foam partial cleaning device, there is a certain time delay between the distance from the water outlet unit 21 stopping to outlet water, and the clothes can be wetted by using the time delay.

[0146] Furthermore, a time delay can be set for the water outlet unit 21 changing from the trigger state to the non-trigger state after the first sensing unit 22 senses the blocking object, and the set time delay can ensure that the water is sufficient to wet the clothes. The time delay can be set for the foam generating unit 23 changing from the non-trigger state to the trigger state after the second sensing unit 24 senses the blocking object, so that the water outlet and the detergent outlet can be seamlessly connected.

[0147] Further, after the control of the detergent foam generating assembly in the triggered state, the method comprises: controlling the detergent foam generating assembly to start to dispense detergent for a set time and then pause until it is determined again whether the sensing end of the detergent foam generating assembly is within the triggering distance from the blocking object.

[0148] The above method can prevent the liquid from being dispensed more than once due to false triggering.

[0149] It should be noted that a mark indicating the triggering position can be provided on the washing tub or the shell 1 of the washing machine so that the user can accurately place the clothes within the triggering range of the first sensing unit 22 and the second sensing unit 24.

[0150] In an alternative embodiment, after the control of the water dispensing assembly in the triggered state, the method comprises: controlling the water dispensing assembly to start to dispense water; and determining whether the detergent foam generating assembly starts to dispense detergent, and if so, controlling the water dispensing assembly to pause to dispense water.

[0151] For some special needs of the user, for example, the user does not want to apply the foam detergent when the clothes are wet, and the user places the clothes under the foam partial cleaning device, and should pay special attention not to place the clothes under the water dispensing unit 21. At this time, the first sensing unit 22 cannot sense the blocking object, and the water continues to be dispensed, but the second sensing unit 24 senses the blocking object, and controls the foam generating unit 23 to dispense the detergent foam. At this time, the control unit detects that the foam generating unit 23 is in the triggered state and starts to dispense the detergent, and then controls the water dispensing unit 21 to stop to dispense water even if the first sensing unit 22 does not sense the blocking object.

[0152] The above only describes the preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been described above with reference to the preferred embodiments, it is not intended to limit the present application, and any person skilled in the art can make some minor changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application to obtain equivalent embodiments with equivalent changes. Any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application are still within the scope of the present application.
