Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a washing equipment and a control method thereof. Background Art

[0002] Washing equipment that can wash clothes, such as washing machines, are easy to operate and have ideal cleaning results. They can free people from complicated housework and have become household appliances that are commonly owned by families today. After washing clothes, most current washing machines use centrifugal dehydration to reduce the water content of the clothes, thereby avoiding the phenomenon of dripping when users take out clothes to dry. However, the centrifugal dehydration method requires the washing tub to reach a very high rotation speed, which often produces a lot of noise during the dehydration process, affecting the user experience. When the amount of laundry is small, it is easy for the clothes to be unevenly distributed in the washing tub during dehydration, resulting in eccentric rotation, which will further increase the noise generated and, in severe cases, cause the tub to hit the drum.

[0003] On the other hand, washing machines using centrifugal dehydration generally require a large space around the washing tub inside the washing machine to prevent the washing tub from shaking and hitting the machine during high-speed rotation. Furthermore, a water collection device is required outside the washing tub to collect the dewatered water and drain it out of the washing machine, further reducing the space available for the washing tub inside the washing machine, resulting in low internal space utilization.

[0004] In the current market environment, as people's material living standards improve, the demand for automatic laundry is not limited to large items of clothing. Smaller items, such as socks and underwear, are also becoming increasingly popular. However, for hygiene reasons, these small items cannot be mixed with larger items. Conventional laundry machines, however, waste excessive water consumption and are difficult to avoid eccentricity during dehydration. Therefore, to meet this demand, small laundry products have gradually entered households.

[0005] These small-sized laundry appliances typically have simple structures and limited functions, along with relatively small washing capacities. For ease of use, their overall size is also relatively small. Consequently, small-sized laundry appliances lack the complex internal structures of conventional laundry equipment and are unable to implement centrifugal dehydration. Modifying the internal structure of small-sized laundry appliances to implement centrifugal dehydration would inevitably increase the overall size of the appliance, significantly reducing user convenience.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a washing device with a flexible washing barrel and a control method thereof. During dehydration, the air in the flexible washing barrel can be sucked out by a suction pump, and the deformation of the flexible washing barrel creates a squeezing effect on the clothes inside, which is beneficial to improving the dehydration rate of the clothes and improving the user experience.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A washing device comprising:

[0010] a wash tub made at least in part of a flexible material;

[0011] The suction pump is communicated with the interior of the washing tub and is used to suck air from the interior of the washing tub.

[0012] Furthermore, the washing tub includes a pleated portion formed of a flexible material; when the suction pump sucks air inside the washing tub, the pleated portion contracts and compresses the space inside the washing tub; when the suction pump stops working, the pleated portion expands and air enters the washing tub;

[0013] Preferably, the pleated portion is provided on the washing tub near the tub opening and contracts / stretches in a direction parallel to the axis of the washing tub.

[0014] Furthermore, it also includes a beating device, which is arranged outside the washing tub and is used to beat the portion of the washing tub made of the flexible material;

[0015] Preferably, the bottom area of ​​the washing tub is made of a flexible material, and the beating device beats the bottom area of ​​the washing tub outside the washing tub.

[0016] Furthermore, the beating device comprises:

[0017] a driving mechanism having a rotatable output end;

[0018] A beating mechanism is connected to the output end of the driving mechanism and includes a plurality of beating members distributed along the circumference of the output end. The beating members extend radially outward from the outer periphery of the output end for a certain length. The extended ends of the beating members beat the washing tub as the output end rotates.

[0019] Preferably, the extending end of the hammering member has a spherical hammering portion.

[0020] Further, the suction pump is connected to the bottom of the washing tub;

[0021] Preferably, the suction pump is a diaphragm pump.

[0022] Another object of the present invention is to provide a method for controlling the washing machine described above, comprising the following steps:

[0023] S1, the washing equipment receives the dehydration instruction and turns on the suction pump;

[0024] S2, reaching the first set condition, turning off the suction pump;

[0025] S4, start the suction pump again;

[0026] S5. When the second set condition is reached, the suction pump is turned off.

[0027] Furthermore, the first setting condition is: the air pressure in the washing tub reaches a preset air pressure threshold, or the suction pump continues to work for a preset working time;

[0028] Preferably, the first setting condition is that after the air pressure in the washing tub reaches a preset air pressure threshold, the suction pump continues to work for a first preset time period.

[0029] Furthermore, the second setting condition is: the air pressure in the washing tub reaches a preset air pressure threshold, or the suction pump continues to work for a second preset time after being turned on again.

[0030] Furthermore, the washing device further comprises a beating device for beating the portion of the washing tub made of the flexible material from the outside of the washing tub;

[0031] Between steps S2 and S4, step S3 is also included: controlling the beating device to beat the washing tub;

[0032] Preferably, after the beating device continuously beats the washing tub for a third preset time period, the beating device is controlled to stop beating and the suction pump is turned on again.

[0033] Furthermore, before step S1, step S0 is also included: during the washing process, controlling the beating device to beat the washing tub.

[0034] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0035] In the present invention, the washing tub made of flexible material can be deformed when the suction pump sucks the air inside the washing tub, compressing the internal space of the washing tub, thereby squeezing the clothes inside the washing tub, and then squeezing the wet clothes to fully remove the moisture therein, which is beneficial to improving the dehydration rate of the clothes.

[0036] In this invention, the suction pump is turned off and then on again during the dehydration process. While the suction pump is off, outside air enters the washing tub, causing it to re-expand and freeing the clothes from compression. When the suction pump is turned on again, the tub deforms, squeezing the clothes a second time. Compared to methods that continuously squeeze the clothes for extended periods, this reduces the risk of damage and helps fully squeeze out the water, further improving the dehydration rate.

[0037] In the present invention, a beating device is provided in the washing machine. When the suction pump is off, the portion formed of the flexible material on the washing tub is beaten, causing the beaten portion of the washing tub to deform, causing the clothes inside the washing tub to flip over and redistribute the clothes within the washing tub. When the suction pump is turned on again to deform the washing tub, the relative positions of the clothes within the washing tub change. Some clothes that were not fully squeezed the previous time may move to positions where they can be squeezed more strongly, so that the clothes in the washing tub are squeezed more evenly and thus fully dehydrated.

[0038] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a direct connection or an indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] This embodiment provides a washing device and a control method thereof.

[0048] like Figure 1 As shown, the washing equipment includes:

[0049] A washing tub 100, at least partially made of a flexible material;

[0050] The suction pump 200 is communicated with the interior of the washing tub 100 and is used to suck air inside the washing tub 100 .

[0051] In the above solution, the washing machine uses a suction pump 200 to draw air from the washing tub 100 for dehydration. When the suction pump 200 is turned on, a negative pressure is created inside the washing tub 100. Because the washing tub 100 includes a flexible portion, it deforms under the pressure differential between the inside and outside of the washing tub 100, compressing the space within the washing tub 100. This squeezes the clothing inside through the tub wall 110 or bottom 120 of the washing tub 100, achieving squeeze-type dehydration of the clothing, fully squeezing out moisture from the clothing and improving the dehydration rate.

[0052] Compared with the centrifugal dehydration method in traditional washing machines, the above-mentioned clothing dehydration method has a simpler structure and only requires a suction pump 200 to effectively dehydrate the clothes. It is especially suitable for small washing equipment for washing small pieces of clothing, avoiding the washing equipment being too large and inconvenient to use.

[0053] In this embodiment, the suction pump 200 is turned on after the clothes are washed. After the suction pump 200 is turned on, the water in the washing tub 100 is first pumped out, and then the air in the washing tub 100 is further sucked out, causing the washing tub 100 to deform, thereby squeezing the clothes for dehydration.

[0054] The suction pump 200 is connected to the bottom of the washing tub 100 and draws water and air from the bottom area of ​​the washing tub 100. Clothes and water in the washing tub 100 are concentrated in the bottom area of ​​the washing tub 100. The suction pump 200 acts on the bottom of the washing tub 100, facilitating more efficient drainage. The suction action of the suction pump 200 can also directly act on damp clothing at the bottom of the washing tub 100, directly drawing a certain amount of water from the damp clothing. Furthermore, gravity facilitates the extraction of air from the bottom of the washing tub 100 by the suction pump 200, thereby improving the efficiency of vacuuming the washing tub 100.

[0055] Specifically, a connecting port 121 connected to the suction pump 200 is provided on the bottom 120 of the washing tub 100, and the suction pump 200 is arranged below the washing tub 100, which can simplify the connecting structure between the washing tub 100 and the suction pump 200 to the greatest extent and avoid the internal structure of the washing equipment being too complicated.

[0056] In detail, the bottom 120 of the washing tub 100 has a hemispherical structure, and the communication port 121 is arranged at the lowest point of the bottom 120 , which is conducive to the collection of washing water and clothes at the bottom 120 under the action of gravity.

[0057] In this embodiment, the suction pump 200 is preferably a diaphragm pump, which can meet the needs of sucking washing water and air at the same time.

[0058] In a further embodiment of this embodiment, the washing tub 100 includes a pleated portion 111 formed of a flexible material. When the suction pump 200 draws air into the washing tub 100, the pleated portion 111 contracts, compressing the space within the washing tub 100. When the suction pump 200 stops working, the pleated portion 111 expands, allowing air to enter the washing tub 100.

[0059] Preferably, the pleated portion 111 is provided on the washing tub 100 near the tub opening and contracts / expands in a direction parallel to the axis of the washing tub 100 .

[0060] Specifically, the pleated portion 111 is disposed on the wall 110 of the washing tub 100 and surrounds the wall 110, forming a corrugated region near the opening of the washing tub 100. A sealing structure is provided at the opening of the washing tub 100 to seal the washing tub 100 and form a relatively enclosed space when the washing machine is operating. When the suction pump 200 is operating, negative pressure is generated within the washing tub 100, causing the pleated portion 111 to contract, displacing the opening toward the bottom 120. After the suction pump 200 stops operating, air returns to the washing tub 100, causing the pleated portion 111 to expand and displacing the opening away from the bottom 120.

[0061] The arrangement of the pleated portion 111 creates a certain compressible space in the longitudinal direction inside the washing tub 100, providing a certain buffering effect when the suction pump 200 sucks air from the washing tub 100, thereby preventing the washing tub 100 from being damaged by a large internal impact force generated when it is deformed.

[0062] In a further embodiment of the present invention, the washing machine further comprises a beating device, which is arranged outside the washing tub 100 and is used to beat the portion of the washing tub 100 made of a flexible material. A local area of ​​the washing tub 100 is beaten by the beating device and deformed, and the impact force received can be transmitted to the clothes inside the washing tub 100. The beating device is controlled to beat the washing tub 100 during the washing process, and the hammering washing of the clothes can also be achieved. When the amount of water in the washing tub 100 is small, the washing tub 100 is beaten by the beating device and deformed, and the clothes inside can also be turned over, thereby redistributing the clothes in the washing tub 100, which is conducive to more sufficient squeezing and dehydrating the clothes after the suction pump 200 is turned on.

[0063] In a preferred solution of this embodiment, the bottom area of ​​the washing tub 100 is made of a flexible material, and the beating device beats the bottom area of ​​the washing tub 100 outside the washing tub 100 .

[0064] Specifically, the beating device is arranged on the right side of the washing tub 100 , and the bottom 120 of the washing tub 100 and the area on the tub wall 110 near the bottom 120 , at least the part facing the right side, are made of flexible material.

[0065] In the preferred embodiment of this invention, the entire washing tub 100 is made of a flexible material, such as rubber. When the suction pump 200 draws air from the washing tub 100, various parts of the washing tub 100 are deformed, thereby maximally compressing the interior of the washing tub 100. When the beating device strikes the washing tub 100, in addition to the areas directly struck, other areas of the washing tub 100 are also deformed to a certain extent, thereby enhancing the beating and squeezing effect on the clothes and making it easier for the clothes to flip within the washing tub 100.

[0066] In this embodiment, the beating device specifically includes:

[0067] a driving mechanism having a rotatable output end 310;

[0068] The beating mechanism is connected to the output end 310 of the driving mechanism and includes a plurality of beating members 320 distributed circumferentially along the output end 310. The beating members 320 extend radially outward from the outer periphery of the output end 310 for a certain length. The extended ends of the beating members 320 beat the washing tub 100 as the output end 310 rotates.

[0069] Preferably, the extending end of the hammering member 320 has a spherical hammering portion 321 .

[0070] In detail, the hammering member 320 includes a connecting rod 322, which is arranged along the radial direction of the output end 310, one end of which is connected to the outer periphery of the output end 310, and the other end of which is connected to a spherical hammering portion 321. The diameter of the hammering portion 321 is greater than the width of the connecting rod 322.

[0071] In the present embodiment, four hammering members 320 are evenly distributed on the output end 310, and the connecting rods 322 of two adjacent hammering members 320 are perpendicular to each other. The driving mechanism includes a motor that drives the output end 310 to rotate. When the motor is turned on and drives the output end 310 to rotate, the hammering members 320 can be driven to rotate around the rotation axis of the output end 310. The four hammering members 320 hammer the outer wall of the washing tub 100 in sequence.

[0072] like Figure 1 and Figure 2 As shown, in this embodiment, the control method of the washing equipment includes the following steps:

[0073] S1, the washing equipment receives a dehydration instruction and turns on the suction pump 200;

[0074] S2, when the first set condition is reached, the suction pump 200 is turned off;

[0075] S4, start the suction pump 200 again;

[0076] S5. When the second set condition is reached, the suction pump 200 is turned off.

[0077] During the above process, after the washing machine receives the dehydration command, the suction pump 200 starts to draw air from the washing tub 100. The pressure differential between the inside and outside of the washing tub 100 causes it to deform, squeezing the clothes inside for the first time. Because the outer layers of clothing come into contact with the deformed washing tub 100 and are directly squeezed, the majority of the water squeezed out comes from the outer layers, leaving less water in the inner layers.

[0078] After reaching the first set condition, the suction pump 200 is turned off, air enters the washing tub 100, and the washing tub 100 returns to its initial state, and the clothes are no longer squeezed. In this process, the water content of the inner clothes can diffuse to the outer clothes to a certain extent.

[0079] After the suction pump 200 is turned on again, the washing tub 100 is deformed again, squeezing the clothes therein for a second time, thereby being able to squeeze out the water in the clothes more fully and improving the overall dehydration rate of the clothes.

[0080] If the clothes are squeezed only once, even if the squeezing time is extended, it is difficult to fully squeeze the water out of the inner layer of clothing. If the laundry is small, the clothes may be damaged due to excessive squeezing force. The solution of this embodiment shuts off the suction pump 200 during the dehydration process, then restarts it, squeezing the clothes a second time. This effectively reduces the moisture content of the clothes after dehydration and provides a better user experience.

[0081] In this embodiment, a diaphragm pump is used as the suction pump 200, and the opening and closing of the diaphragm pump is controlled by controlling the power on and off of the diaphragm pump.

[0082] The first set condition may be that the air pressure in the washing tub 100 reaches a preset air pressure threshold. The washing apparatus is provided with a detection device for detecting the air pressure in the washing tub 100, and the suction pump 200 is controlled to be turned off based on the air pressure in the washing tub 100 fed back by the detection device.

[0083] Alternatively, the first set condition may also be: the suction pump 200 continues to work for a preset working time. The washing device controls the suction pump 200 to turn off according to the continuous working time of the suction pump 200.

[0084] Similarly, the second set condition may be that the air pressure in the washing tub 100 reaches a preset air pressure threshold.

[0085] Alternatively, the second setting condition may also be: the suction pump 200 continues to work for a preset working time after being turned on again.

[0086] In a preferred solution of this embodiment, the first setting condition is: after the air pressure in the washing tub 100 reaches a preset air pressure threshold, the suction pump 200 continues to work for a first preset time period.

[0087] The second setting condition is that the suction pump 200 continues to work for a second preset time after being turned on again.

[0088] In the above solution, after receiving the dehydration command, the washing machine controls the suction pump 200 to start, first pumping out most of the water in the washing tub 100. The suction pump 200 then continues to operate to pump out the air in the washing tub 100. When the air pressure in the washing tub 100 detected by the detection device reaches the air pressure threshold, the suction pump 200 continues to operate for a first preset time period, keeping the air pressure in the washing tub 100 at a low level for a period of time, thereby ensuring an effective squeezing effect.

[0089] After the suction pump 200 is turned on again, the shut-down time of the suction pump 200 is determined by the continuous working time of the suction pump 200 to ensure that as much water as possible in the clothes is removed.

[0090] In the specific solution of this embodiment, the setting values ​​of the first preset time length and the second preset time length are the same, that is, the squeezing time of the clothes after two air pumpings is basically the same, thereby achieving a good dehydration effect.

[0091] In a further solution of this embodiment, step S3 is further included between steps S2 and S4: controlling the beating device to beat the washing tub 100 .

[0092] In the above embodiment, after the air in the washing tub 100 is first sucked out and the clothes in the tub are first squeezed, the pounding device beats the washing tub 100 while the suction pump 200 is off, causing the clothes in the tub to turn over and accelerating the diffusion of moisture from the clothes to the outer layers. When the suction pump 200 is turned on again to suck air from the tub, the dehydration rate of the clothes is further improved.

[0093] Specifically, after the beating device continuously beats the washing tub 100 for a third preset time period, the beating device is controlled to stop beating and the suction pump 200 is turned on again.

[0094] Specifically, after the suction pump 200 is turned off, the motor of the drive mechanism is turned on, driving the output end 310 to rotate, thereby causing the hammering portions 321 of the four hammering members 320 to hammer the outer wall of the washing tub 100 in sequence. After a third predetermined time period, the motor is turned off, and the output end 310 stops rotating. Simultaneously, the suction pump 200 is turned on again to suck air from the washing tub 100.

[0095] The third preset time period can be adjusted according to the amount of laundry to be washed. The beating device continuously beats the washing tub 100, thereby dispersing the clothes that have been squeezed and clumped together, and then further turning them over in the washing tub 100. Clothes in the inner layer with a relatively high water content can be turned over to the outer layer during the above process, while clothes originally in the outer layer have been mostly dehydrated and can be turned over to the inner layer where they are no longer significantly dehydrated during the air suction process.

[0096] When the suction pump 200 is turned on again, it sucks air from the washing tub 100, causing it to deform and squeeze the clothes inside the tub a second time. Because the distribution of the clothes inside the tub changes after the beating process of the beating device, the inner layer of clothes that had less water removed during the first squeezing process are flipped to the outer layer, allowing the water in these clothes to be fully removed during the second suction of air from the tub.

[0097] Between the two times the suction pump 200 sucks the air in the tub, the beating device drives the clothes in the washing tub 100 to turn over, so that during the two times of sucking the air in the tub, the moisture in the inner and outer layers and the inner layer of the clothes in the tub can be fully removed respectively, ensuring a high dehydration rate of the clothes.

[0098] In this embodiment, step S0 is further included before step S1: during the washing process, controlling the beating device to beat the washing tub 100 .

[0099] When washing clothes, the washing apparatus of this embodiment does not need to rotate the washing tub 100 itself, nor does it require a stirring device to agitate the washing water. Instead, the washing process is completed by beating the outer wall of the washing tub 100 with a beating device. Specifically, the beaten area of ​​the washing tub 100 deforms, transmitting the impact force to the water and clothes inside the washing tub 100. The impact force causes the washing water to flow within the tub, simultaneously driving the clothes to move within the tub, creating friction between the clothes and between the clothes and the water flow, thereby achieving a good washing effect.

[0100] In a further solution of this embodiment, in step S0 and step S3 , when the beating device beats the washing tub 100 , the rotation direction of the output end 310 is opposite.

[0101] Specifically, during the washing process, that is, in step S0, the output end 310 rotates counterclockwise (eg Figure 1 The hammering portion 321 is driven by the hammering element 321 to hammer the wall 110 of the washing tub 100 obliquely downward (as indicated by the arrow in the figure). The hammered area of ​​the washing tub 100 is close to the top of the washing water in the tub, which helps to transmit the impact force to the washing water, thereby effectively stirring the washing water. At the same time, the concave deformation of the wall 110 of the washing tub 100 can squeeze the clothes to a certain extent, which is conducive to improving the washing effect of the clothes.

[0102] During the dehydration process, specifically during the period when the suction pump 200 is turned off during dehydration, that is, in step S3, the output end 310 rotates clockwise (such as Figure 1 The beating unit 321 is driven by the beating part 321 to beat the bottom 120 of the washing tub 100 upward during dehydration. During dehydration, the beating device is mainly used to turn over the clothes in the tub so that the clothes are redistributed in the washing tub 100. The beating part 321 beats the bottom 120 from below, so that the clothes in the tub are subjected to an upward impact force, which can more effectively turn over the clothes in the tub.

[0103] The washing machine of this embodiment uses a washing tub 100 made of a flexible material to hold clothes. A suction pump 200 is provided in communication with the washing tub 100. The suction pump 200 draws air from the tub, causing the washing tub 100 to deform to a certain extent, thereby squeezing the clothes for dehydration. During the dehydration process, the suction pump 200 is turned off and then on again. While the suction pump 200 is off, outside air enters the washing tub 100 and simultaneously strikes the outer wall of the washing tub 100, causing the clothes to flip and redistribute the inner and outer layers of clothing within the tub. By sucking air from the washing tub 100 twice, the suction pump 200 does not need to run continuously for long periods of time, and can achieve an ideal dehydration rate for the clothes.

[0104] The structure and control method of the above-mentioned washing device are particularly suitable for small washing devices for washing small pieces of clothing. The internal structure of the washing device is simple, which can reduce the overall volume of the washing device. At the same time, the washing device has a clothing dehydration function, a high dehydration rate, and a good user experience.

[0105] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
