Description

TECHNICAL FIELD

[0001] The present application belongs to the field of washing technology, and particularly relates to a washing device and a control method. BACKGROUND

[0002] In today's daily life, with the continuous development of society, people pay more attention to their own health conditions. Accordingly, people are more diligent in laundry, but the experience of hand washing is not very good. Therefore, the emergence of full-automatic washing machine liberates people from the labor of manual washing and becomes one of the indispensable household appliances. There are two common types of washing devices at present, which are drum washing machine and roller washing machine. The drum washing machine is designed with a wave wheel structure at the bottom of the washing drum, and the wave wheel rotates in the forward and reverse directions during the washing process, so that the water flow in the drum forms different vortexes. The clothes are rolled with the water flow and also produce mutual friction, thereby achieving the effect of washing clothes. The drum washing machine uses the mechanical work of the motor to make the drum rotate, and the clothes are lifted to a high place and then fall, so that the repeated motion can achieve the washing of clothes.

[0003] Compared with outerwear and trousers, small clothes such as underwear and underpants are washed more frequently. The capacity of the traditional washing device (such as drum washing machine or roller washing machine) is large, and if small clothes are washed frequently, it will be a waste of resources. In addition, small clothes are usually small in size, which leads to an unexpected cleaning effect.

[0004] At present, small washing devices for washing small clothes have also appeared on the market. The washing device uses a washing cylinder to carry clothes, the cylinder wall has protrusions, and the washing cylinder rotates continuously in one direction to rub the clothes and wash the small clothes. However, this rubbing washing method causes great wear and tear to the clothes, and thus is not satisfactory.

[0005] In order to solve this problem, the applicant proposed a solution in the application number 202110605197.1 on May 31, 2021, which realized washing by periodic movement of the extrusion part to extrude the flexible washing drum. However, in actual use, it is found that sometimes the extrusion part is in the extrusion state after washing, which causes the clothes to be squeezed and difficult to take out or not easy to take out.

[0034] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions. For example, although the description in the specification is exemplified by taking the driving part as a hydraulic cylinder or a gas cylinder, the present application can obviously use other similar means, such as an electric push rod, as long as the driving part can drive the pressing part to perform the squeezing washing on the flexible washing drum.

[0035] It should be noted that in the description of the present application, the terms of direction or position relationship such as "center", "upper", "lower", "inner", "outer" and the like are based on the direction or position relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "providing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, etc. 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.

[0037] To solve the technical problem that the squeezing part is just in the squeezing state at the end of washing, causing the clothes to be squeezed and not easy to take out or not easy to take out, etc. in the prior art washing device which performs washing on the washing object by reciprocating squeezing washing, Figures 1-6As shown, this invention provides a washing device, including a support 1, a flexible washing tub 2, a squeezing part 3, and a driving part 4. The flexible washing tub 2 is fixedly mounted on the support 1 and also has a drain outlet (not shown in the figure). The flexible washing tub 2 includes an outer tub 21 and an inner tub 22. The outer tub 21 is fixedly mounted on the support 1, and the inner tub 22 is detachably disposed inside the outer tub 21. The squeezing part 3 and the driving part 4 are both located outside the flexible washing tub 2. The squeezing part 3 is pivotally connected to the support 1, and there are two squeezing parts 3. One end of the squeezing part 3 (specifically as shown in the figure) Figure 3 The top end of the squeezing part 3 shown in the figure abuts against the flexible washing tub 2, and the other end of the squeezing part 3 (specifically as shown in the figure) Figure 3 The bottom end of the extrusion section 3 shown is driven to the output end of the drive section 4. Driven by the drive section 4, the extrusion section 3 periodically approaches and extrudes the flexible washing tub 2 or moves away from and releases the extrusion. The portion of the extrusion section 3 pivotally connected to the support 1 is located between the two ends of the extrusion section 3. A return spring 7 is also provided between the extrusion section 3 and the support 1, with both ends connected to the extrusion section 3 and the support 1 respectively. The end of the return spring 7 connected to the extrusion section 3 is located between the pivotally connected position of the extrusion section 3 to the support 1 and the end of the extrusion section 3 that abuts against the flexible washing tub 2. An extrusion block 8 is also fixedly provided at the end of the extrusion section 3 that abuts against the flexible washing tub 2. The top of the flexible washing tub 2 is also provided with a cover 6, which has a gas channel 61 and a gas valve 62. When the extrusion section 3 approaches and abuts against the flexible washing tub 2, the height of the center of the contact portion between the extrusion section 3 and the flexible washing tub 2 is lower than the height of the center of the flexible washing tub 2. When the squeezing part 3 squeezes from the bottom of the flexible washing tub 2, it can push the laundry upwards. When the squeezing part 3 releases the squeeze, the laundry tumbles and falls, which can improve the washing effect.

[0038] The extrusion section 3 includes two extrusion arms 31, such as Figures 2-5 As shown, the two squeezing arms 31 are detachably connected as a single unit. Adjacent ends of the two squeezing arms 31 are connected by a torsion spring 32, which is pivotally connected to the bracket 1. During normal washing, the two squeezing arms 31 do not move relative to each other due to the torsion of the torsion spring 32. However, if there is too much laundry in the flexible washing tub 2, causing the squeezing arms 31 to jam and fail to squeeze effectively, the lower squeezing arm 31, driven by the cam 42, can overcome the torsion of the torsion spring 32 and continue moving, thus preventing the cam 42 from jamming.

[0039] The drive unit 4 includes a motor 41 and a cam 42. The output end of the motor 41 is driven and connected to the cam 42. The cam 42 abuts against the end of the extrusion unit 3 near the drive unit 4.

[0040] like Figures 2-3As shown in FIG. 6, the washing machine further comprises a position sensing part 5 configured to feed the position of the pressing part 3 to a processor (not shown in the figure) of the washing machine to determine whether the pressing part 3 is currently pressing the flexible washing barrel 2. The position sensing part 5 comprises a first reed switch 51 and a first magnet 52. The first magnet 52 is fixed on the cam 42, and the first reed switch 51 is fixed on the bracket 1 near the cam 42. When the pressing part 3 pivots, the distance between the first reed switch 51 and the first magnet 52 changes, and the first reed switch 51 periodically disconnects or connects. Specifically, as shown in FIG. 6, the first magnet 52 is fixed on both ends of the long axis of the cam 42, and the first reed switch 51 is arranged on the bracket 1. When the pressing part 3 is not pressing the flexible washing barrel 2, the first reed switch 51 is closest to one of the two first magnets 52. At this time, the processor detects that the first reed switch 51 is connected, indicating that the pressing part 3 is not pressing the flexible washing barrel 2. Figure 6

[0041] The washing machine further comprises a backup power supply (not shown in the figure) connected to the driving part 4 and the position sensing part 5. Thus, when the power supply is unexpectedly interrupted and the washing machine is in a state where the washing object is pressed by the pressing part 3, the backup power supply can drive the driving part 4 to a position where the flexible washing barrel 2 is not pressed, so as to avoid the washing object being pressed for a long time and affecting the service life, and facilitate the washing object being taken out when the power supply cannot be restored in a certain time.

[0042] It should be noted that the above embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust the above structure without departing from the principles of the present application, so that the present application can be applied to more specific application scenarios. These do not deviate from the principles of the present application, and thus fall within the protection scope of the present application.

[0043] For example, in an alternative embodiment, the driving part 4 can be a hydraulic cylinder or a pneumatic cylinder, and the output end of the driving part 4 abuts against one end of the pressing part 3 which does not abut against the flexible washing barrel 2 (not shown in the figure). At this time, the first reed switch 51 and the first magnet 52 can be replaced by a second reed switch and a second magnet. One of the second reed switch and the second magnet is fixed on the output end of the driving part 4, and the other is fixed on the end of the pressing part 3 near the driving part 4 (not shown in the figure). When the pressing part 3 pivots, the distance between the second reed switch and the second magnet changes, and the second reed switch periodically disconnects or connects.

[0044] For example, in another alternative embodiment, the first reed switch 51 can also be provided as two (not shown in the figure). ​

[0045] For example, in another alternative embodiment, the first reed switch 51 can be fixed to the cam 42, and the first magnet 52 can be fixed to the bracket 1 near the cam 42 (not shown in the figure).

[0046] For example, in another alternative embodiment, the first reed switch 51 and the first magnet 52 can be replaced by an infrared sensor (not shown in the figure). Specifically, the first magnet 52 can be omitted, and the infrared sensor can be arranged at the position of the first reed switch 51. The infrared sensor can be arranged on the bracket 1 near the cam 42, and specifically, can be arranged at the bottom end of the cam 42. By virtue of the structural feature that the cam 42 has a long axis and a short axis, when the cam 42 rotates, the areas that can be blocked by the two ends of the long axis and the two ends of the short axis of the cam 42 are different. When the two ends of the long axis of the cam 42 block the infrared sensor, the infrared rays emitted by the infrared sensor are reflected by the cam 42 and then accepted by the infrared sensor again, indicating that the squeezing part 3 is in a state of not squeezing the flexible washing tub 2.

[0047] For example, in another alternative embodiment, the first reed switch 51 and the first magnet 52 can be replaced by a third reed switch and a third magnet, one of which is fixed to the bracket 1, and the other of which is fixed to the squeezing part 3 (not shown in the figure). When the squeezing part 3 pivots and rotates, the distance between the third reed switch and the third magnet changes, and the third reed switch periodically disconnects or connects.

[0048] For example, in another alternative embodiment, the height of the center of the contact part of the squeezing part 3 with the flexible washing tub 2 can also be higher than or equal to the height of the center of the flexible washing tub 2 (not shown in the figure).

[0049] In addition, the present application also provides a control method of a washing device, the washing device comprising a bracket 1, a flexible washing tub 2, a squeezing part 3 and a driving part 4, the flexible washing tub 2 being fixed to the bracket 1, the squeezing part 3 and the driving part 4 both being arranged outside the flexible washing tub 2, the squeezing part 3 being pivotally connected to the bracket 1, and the output end of the driving part 4 being drivingly connected to the squeezing part 3; under the driving of the driving part 4, the squeezing part 3 periodically approaches and squeezes the flexible washing tub 2 or moves away and releases the squeezing of the flexible washing tub 2; the washing device further comprises a position sensing part 5, which is arranged to be able to feed back the position of the squeezing part 3 to the processor of the washing device to determine whether the squeezing part 3 currently squeezes the flexible washing tub 2;

[0050] The control method comprises the following steps:

[0051] S1, controlling the pivoting rotation of the squeezing part 3 and reciprocally squeezing the flexible washing tub 2;

[0052] S2, controlling the squeezing part 3 to reduce the frequency of pivotal rotation at the end of washing;

[0053] S3, when the processor receives the feedback of the position sensing part 5, controlling the squeezing part 3 to stop rotating at a preset position.

[0054] In summary, the washing device of the present application can obtain a better washing effect by the reciprocating squeezing washing mode, and the degree of wear of the washing object is small during the washing process. On this basis, the washing device of the present application is further provided with a position sensing part, and the squeezing part can be in a state of not squeezing the flexible washing barrel after washing, which is convenient for taking out the washing object in the flexible washing barrel. And the present application also sets up a standby power supply, so that even in the case of power failure, the squeezing part can be adjusted to be in a state of not squeezing the flexible washing barrel.

[0055] Those skilled in the art can understand that the above washing device also includes some other well-known structures, such as processors, controllers, memories, etc., wherein the memory includes but is not limited to random access memory, flash memory, read-only memory, programmable read-only memory, volatile memory, non-volatile memory, serial memory, parallel memory or register, etc., and the processor includes but is not limited to CPLD / FPGA, DSP, ARM processor, MIPS processor, etc. In order not to unnecessarily obscure the embodiments of the present application, these well-known structures are not shown in the drawings.

[0056] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
