[0045] The present application provides a clothes processing device, which may be a washing machine, a shoe washing machine, a washer-dryer or other equipment for processing clothes. Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of the clothes processing device provided by an embodiment of the present application in a first state. Figure 2The schematic diagram of the structure of the clothes processing device provided by the embodiment of the present application in the second state is as follows: The clothes processing device 10 comprises a housing 100, an outer tub 200, an inner tub 300 and a telescopic device 400.
[0046] The outer barrel 200 and the inner barrel 300 are arranged in the box body 100, and the outer barrel 200 is sleeved on the outside of the inner barrel 300; the telescopic device 400 includes a fixed end 410 and a movable end 420, the fixed end 410 is fixedly connected to the box body 100, and the movable end 420 is suitable for connecting with the outer barrel 200 or the inner barrel 300. The telescopic device 400 can telescopically make the movable end 420 approach or move away from the fixed end 410 to drive the outer barrel 200 and the inner barrel 300 to move relative to each other, thereby changing the relative height of the outer barrel 200 and the inner barrel 300.
[0047] It should be noted that when the moving end 420 is connected to the outer barrel 200, the telescopic device 400 can telescopically move the moving end 420 close to or away from the fixed end 410 to drive the outer barrel 200 to move up and down relative to the inner barrel 300 and the box 100, thereby changing the relative height of the outer barrel 200 and the inner barrel 300; when the moving end 420 is connected to the inner barrel 300, the telescopic device 400 can telescopically move the moving end 420 close to or away from the fixed end 410 to drive the inner barrel 300 to move up and down relative to the outer barrel 200 and the box 100, thereby changing the relative height of the outer barrel 200 and the inner barrel 300. Changing the relative height of the outer barrel 200 and the inner barrel 300 means that the height of the outer barrel 200 or the inner barrel 300 relative to the ground changes, so that the difference between the heights of the outer barrel 200 and the inner barrel 300 relative to the ground changes. It can be understood that, under the premise that the amount of water in the outer barrel 200 is constant, the higher the height of the inner barrel 300 relative to the outer barrel 200, the lower the water level in the inner barrel 300, and the lower the height of the inner barrel 300 relative to the outer barrel 200, the higher the water level in the inner barrel 300. In this way, by controlling the telescopic device 400 to telescope, the relative height of the outer barrel 200 and the inner barrel 300 can be adjusted, thereby adjusting the water level value in the inner barrel 300.
[0048] The clothes treating device 10 provided in the embodiment of the present application can perform relative movement in the height direction between the inner tub 300 and the outer tub 200. By adding a telescopic device 400 to drive the inner tub 300 or the outer tub 200, the relative height of the outer tub 200 and the inner tub 300 can be adjusted, thereby adjusting the water level value in the inner tub 300. In this way, when the clothes treating device 10 performs a washing program, the corresponding optimal washing water level value can be matched according to the washing stage, and the washing water in the inner tub 300 can reach the optimal water level by controlling the telescopic device 400 to extend and retract, so as to achieve the best treatment effect on the clothes to be treated.
[0049] For example, see Figure 1-Figure 4 , Figure 3 for Figure 1 The structural schematic diagram of the clothes processing device shown in FIG. Figure 4 for Figure 2 The outer barrel 200 and the inner barrel 300 have the same axial and horizontal directions, the housing 100 includes a connecting wall 110 located above the outer barrel 200, a fixed end 410 fixedly connected to the connecting wall 110, and a moving end 420 connected to the circumferential side wall of the outer barrel 200.
[0050] It should be noted that the axial direction of the inner barrel 300 is the extension direction of the rotating shaft of the inner barrel 300, and the axial direction of the outer barrel 200 and the inner barrel 300 is the same as the horizontal direction, which can refer to the drum-type washing machine in the prior art. The connecting wall 110 is, for example, arranged on the top plate of the box body 100, or it can be arranged on the side plate of the box body 100. The fixed end 410 and the connecting wall 110, and the moving end 420 and the outer barrel 200 can be hinged, or screwed, or other connection methods, which are not specifically limited here. The number of telescopic devices 400 can be multiple. Exemplarily, there are two telescopic devices 400, and the two telescopic devices 400 are symmetrically arranged on both sides of the outer barrel 200 in the left and right directions; or, there are four telescopic devices 400, and the four telescopic devices 400 are arranged in sequence in the circumferential direction of the outer barrel 200, and the spacing between each adjacent two telescopic devices 400 is the same.
[0051] In actual application, the box body 100 suspends the outer barrel 200 through the telescopic device 400. Figure 2 and Figure 4 As shown in FIG. 1 , when the length of the telescopic device 400 is contracted, the outer tub 200 is driven to move upward, so that the height of the outer tub 200 relative to the inner tub 300 is increased, and the gap between the bottom of the outer tub 200 and the bottom of the inner tub 300 is reduced. If there is washing water in the outer tub 200, the water level of the washing water in the inner tub 300 will rise; Figure 1 and Figure 3 As shown, when the length of the telescopic device 400 is extended, the outer barrel 200 will be driven to move downward, thereby reducing the height of the outer barrel 200 relative to the inner barrel 300, and the gap between the bottom of the outer barrel 200 and the bottom of the inner barrel 300 will increase. If there is washing water in the outer barrel 200, the water level of the washing water in the inner barrel 300 will decrease.
[0052] For example, see Figure 5 , Figure 5 The telescopic device 400 is a schematic diagram of the structure of the telescopic device provided in the embodiment of the present application. The telescopic device 400 also includes a linear drive mechanism 430 and a shock absorbing mechanism 440 .
[0053] The linear drive mechanism 430 includes a stator 431 and a mover 432, wherein the mover 432 is adapted to perform linear motion relative to the stator 431, wherein one of the stator 431 and the mover 432 is connected to the moving end 420, and the other is connected to the moving end, so as to drive the moving end 420 to approach or move away from the fixed end 410. Optionally, the linear drive mechanism 430 may be a screw motor, or may be composed of a rotary motor, a transmission gear, and a linear motion unit.
[0054] The shock absorbing mechanism 440 can be connected between the linear drive mechanism 430 and the fixed end 410 to cushion the outer barrel 200. Optionally, the shock absorbing mechanism 440 can also be connected between the linear drive mechanism 430 and the moving end 420. It should be noted that when the clothing processing device 10 is in operation, the vibration generated by the rotation of the inner barrel 300 will be transmitted to the outer barrel 200, and the shock absorbing mechanism 440 absorbs the vibration of the outer barrel 200 to reduce the vibration transmitted from the outer barrel 200 to the box 100, thereby reducing the vibration of the box 100 relative to the ground and reducing the noise during the operation of the clothing processing device 10. Exemplarily, the shock absorbing mechanism 440 is a shock absorbing spring, the stator 431 is connected to the moving end, and the mover 432 is connected to the fixed end 410 through the shock absorbing spring. Optionally, the shock absorbing mechanism 440 can also be a damper. In this way, by integrally setting the shock absorbing mechanism 440 in the telescopic device 400, the clothing processing device 10 does not need to be equipped with a separate shock absorbing device for the outer barrel 200, thereby simplifying the installation steps and the internal structure of the clothing processing device 10.
[0055] See also Figure 1-Figure 2 The clothes processing device 10 further includes a water inlet assembly 500 and a water outlet assembly 600 disposed in the housing 100 .
[0056] The water inlet assembly 500 includes a water box 510, a water inlet pipe 520 and a spray device 530. The water box 510 is provided with a water injection port and a delivery port, and is used to store the clothing treatment agent, and is used to connect an external water source through the water injection port, such as a faucet through a water pipe; the water box 510 is used to introduce water from the outside, and after the internal clothing treatment agent and water are mixed to form a clothing treatment mixed liquid, the clothing treatment mixed liquid is output from the delivery port; the water inlet end of the water inlet pipe 520 is connected to the delivery port of the water box 510, and the water outlet end is connected to the liquid inlet of the spray device 530, and is used to introduce the received clothing treatment mixed liquid into the spray device 530; the spray port of the spray device 530 is connected to the interior of the outer barrel 200, and is used to spray the clothing treatment mixed liquid into the outer barrel 200 to treat the clothes in the inner barrel 300. The spray device 530 is, for example, arranged at the top of the outer barrel 200.
[0057] The drainage assembly 600 includes a drainage pipe 610 and a drainage pump 620. The water inlet end of the drainage pipe 610 is connected to the outer tub 200, and the water outlet end is connected to the liquid inlet end of the drainage pump 620. The drainage pipe 610 is used to introduce water in the outer tub 200 into the drainage pump 620; the liquid outlet of the drainage pump 620 is used to communicate with the outside of the clothing processing device 10, and the drainage pump 620 is used to drive the internal water to be discharged from the clothing processing device 10.
[0058] The clothes treating device 10 provided in the embodiment of the present application can perform relative movement in the height direction between the inner tub 300 and the outer tub 200. By adding a telescopic device 400 to drive the inner tub 300 or the outer tub 200, the relative height of the outer tub 200 and the inner tub 300 can be adjusted, thereby adjusting the water level value in the inner tub 300. In this way, when the clothes treating device 10 performs a washing program, the corresponding optimal washing water level value can be matched according to the washing stage, and the washing water in the inner tub 300 can reach the optimal water level by controlling the telescopic device 400 to extend and retract, so as to achieve the best treatment effect on the clothes to be treated.
[0059] The present application also provides a control method for a clothes processing device. For example, see Figure 6 , Figure 6 This is a flow chart of the control method provided in the embodiment of the present application. Figure 1-Figure 4 As shown, the clothing processing device 10 includes a box body 100 and an outer barrel 200, an inner barrel 300 and a telescopic device 400 arranged in the box body 100, the outer barrel 200 is sleeved outside the inner barrel 300, the telescopic device 400 includes a fixed end 410 and a movable end 420, the fixed end 410 is fixedly connected to the box body 100, the movable end 420 is suitable for connecting to the outer barrel 200 or the inner barrel 300, and the telescopic device 400 can telescopically make the movable end 420 close to or away from the fixed end 410; the control method includes the following steps S101-step S102:
[0060] Step S101: Detecting the clothing processing step currently executed by the clothing processing device 10;
[0061] Step S102 : controlling the telescopic device 400 to telescope according to the laundry processing step to drive the outer tub 200 and the inner tub 300 to move relative to each other, thereby changing the relative heights of the outer tub 200 and the inner tub 300 .
[0062] It should be noted that when the laundry processing device 10 performs different laundry processing steps, the corresponding rotation strategies of the inner barrel 300 are different, so that the corresponding optimal water levels of the inner barrel 300 are also different. The telescopic device 400 is controlled to telescope according to the laundry processing steps, with the purpose of adjusting the relative height of the outer barrel 200 and the inner barrel 300 so that the water level in the inner barrel 300 reaches the optimal water level corresponding to the currently executed laundry processing step, thereby enabling the laundry processing device 10 to achieve a better laundry processing effect.
[0063] The control method of the clothing processing device provided in the embodiment of the present application is that the inner barrel 300 and the outer barrel 200 of the clothing processing device 10 can perform relative movement in the height direction, and the extension and retraction device 400 is controlled by the clothing processing step currently executed by the clothing processing device to make the washing water in the inner barrel 300 reach the corresponding optimal water level, which can improve the clothing processing effect of the clothing processing device.
[0064] In some embodiments, see Figure 7 , Figure 7 Another flow chart of the control method provided in the embodiment of the present application. The axial direction of the outer barrel 200 and the inner barrel 300 are the same as the horizontal direction, the clothing processing step performed by the clothing processing device 10 is a weighing step, a water intake step, a uniform speed washing step, a variable speed washing step, a rinsing step, a drainage step or a dehydration step, the maximum speed of the inner barrel 300 when the clothing processing device 10 performs the variable speed washing step is greater than the maximum speed of the inner barrel 300 when the uniform speed washing step is performed, and controlling the telescopic device 400 to telescope according to the clothing processing step includes:
[0065] If the clothes processing step is a weighing step, a drainage step, a dehydration step or a variable speed washing step, the telescopic device 400 is controlled to be telescopic to a first telescopic state; when the telescopic device 400 is in the first telescopic state, the outer tub 200 and the inner tub 300 are coaxially arranged;
[0066] If the clothing processing step is a water intake step, a rinsing step or a uniform speed washing step, the telescopic device 400 is controlled to be telescopic to the second telescopic state; when the telescopic device 400 is in the second telescopic state, the central axis of the outer barrel 200 is located above the central axis of the inner barrel 300.
[0067] It should be noted that when the clothing treatment device 10 is started, the load will be weighed first, for example, the weight of the clothing to be treated in the clothing treatment device 10 will be detected by a built-in weighing sensor. After the weighing is completed, the clothing treatment device 10 will start to take in water. During the water intake process, the water level in the clothing treatment barrel gradually rises until it reaches the preset water level. After the water intake is completed, the clothing treatment device 10 will enter the main washing stage, which includes a uniform speed washing step and / or a variable speed washing step; in the uniform speed washing step, the clothing treatment device 10 will rotate the inner barrel 300 at a constant speed to beat and rinse the load in the inner barrel 300; in the variable speed washing step, the clothing treatment device 10 will continuously change the rotation speed of the inner barrel 300 to achieve a better washing effect. After the main washing stage is completed, the clothing treatment device 10 will enter the rinsing stage. Before the rinsing step, a water intake step needs to be performed. The purpose of rinsing is to use the newly entered clean water to remove the residual clothing treatment agent on the load. The rinsing step usually needs to be performed multiple times. The draining step exists in both the main washing stage and the rinsing stage of the laundry treatment device 10, and its purpose is to drain the dirty washing water out of the laundry treatment device 10. The dehydration step is usually performed after the draining step, and in the dehydration step, the laundry treatment device 10 will spin the inner drum 300 at a high speed to throw out the water in the load.
[0068] It is understandable that when the laundry processing device 10 performs the water intake step, the rinsing step or the uniform speed washing step, the rotation speed of the inner barrel 300 is relatively slow, for example, the rotation speed of the inner barrel in the uniform speed washing step is 50rpm / min; when the laundry processing device 10 performs the weighing step, the drainage step, the dehydration step or the variable speed washing step, the inner barrel 300 is usually required to rotate at a high speed to complete, for example, the rotation speed of the inner barrel 300 in the weighing step is 93rpm / min, the rotation speed of the inner barrel in the weighing and variable speed washing steps is 150rpm / min, and the rotation speed of the inner barrel 300 in the dehydration step is more than 1000r / min. However, the inner barrel 300 is prone to shake greatly when rotating at a high speed, causing problems such as barrel collision, wear, and abnormal noise. Therefore, the present solution can ensure that the gap between the inner tub 300 and the outer tub 200 is in the maximum state by adjusting the outer tub 200 and the inner tub 300 to be coaxially arranged when it is detected that the clothes processing step currently executed by the clothes processing device 10 is a weighing step, a drainage step, a dehydration step or a variable speed washing step, thereby avoiding the collision between the inner tub 300 and the outer tub 200. In addition, when the outer tub 200 and the inner tub 300 are coaxially arranged, the water level in the inner tub 300 is low, so that the resistance from the washing water when the inner tub 300 rotates is reduced, the inner tub 300 is more likely to reach the set high speed, and the loss of the inner tub 300 drive motor is smaller.
[0069] On the other hand, when the laundry processing apparatus 10 is in a state as Figure 1 and Figure 3In the first state shown, the telescopic device 400 is telescoped to the first telescopic state such as the relaxed state, and the water inflow of the laundry processing device 10 needs to reach the first water inflow so that the water level of the inner barrel 300 reaches the target water level; however, when the laundry processing device 10 is in the state such as Figure 2 and Figure 4 In the second state shown, the telescopic device 400 is telescoped to the second telescopic state such as the tight state, and the water intake of the laundry processing device 10 needs to reach the second water intake so that the water level of the inner barrel 300 reaches the target water level, wherein the first water intake is greater than the second water intake. It can be understood that if the water level of the inner barrel 300 is similarly made to reach the target water level, the water intake required when the laundry processing device 10 is adjusted to the first state is greater than the water intake required when the laundry processing device 10 is adjusted to the second state, that is, the laundry processing device 10 is adjusted to the second state for washing clothes, which can achieve the effect of water saving. Therefore, the control method of the present application, by adjusting the laundry processing device 10 to the central axis of the outer barrel 200 being located above the central axis of the inner barrel 300 when the laundry processing step currently executed by the laundry processing device 10 is the water intake step, the rinsing step or the uniform speed washing step, can make the water level of the inner barrel 300 reach the target water level, and the water intake is reduced, thereby achieving the effect of water saving.
[0070] Regarding how to control the telescopic device 400 to telescope according to the clothing processing steps, in addition to determining the control method of the telescopic device 400 according to the specific type of the clothing processing steps, the embodiment of the present application also provides another embodiment, that is, controlling the telescopic device 400 to telescope according to the clothing processing steps includes:
[0071] Acquire the maximum rotation speed of the inner drum 300 when the laundry processing device 10 performs the laundry processing step;
[0072] If the maximum speed is greater than the preset speed threshold, the telescopic device 400 is controlled to telescope to the first telescopic state; when the telescopic device 400 is in the first telescopic state, the outer barrel 200 and the inner barrel 300 are coaxially arranged;
[0073] If the maximum speed is less than or equal to the preset speed threshold, the telescopic device 400 is controlled to telescope to the second telescopic state; when the telescopic device 400 is in the second telescopic state, the central axis of the outer barrel 200 is located above the central axis of the inner barrel 300.
[0074] It should be noted that the maximum speed is greater than the preset speed threshold, which means that when the laundry processing device 10 performs the current laundry processing step, the inner barrel 300 rotates at a high speed, and is prone to large shaking, causing problems such as barrel collision, wear, and abnormal noise. Therefore, by adjusting the laundry processing device 10 to the coaxial arrangement of the outer barrel 200 and the inner barrel 300, it is possible to ensure that the gap between the inner barrel 300 and the outer barrel 200 is in the maximum state, thereby avoiding the inner barrel 300 and the outer barrel 200 from colliding. In addition, when the outer barrel 200 and the inner barrel 300 are coaxially arranged, the water level in the inner barrel 300 is low, so that the resistance from the washing water when the inner barrel 300 rotates is reduced, the inner barrel 300 is easier to reach the set high speed, and the loss of the inner barrel 300 drive motor is smaller.
[0075] If the maximum speed is less than or equal to the preset speed threshold, it means that when the clothing processing device 10 executes the current clothing processing step, the speed of the inner barrel 300 is slow, and there is no need to worry about the barrel collision problem. Therefore, by adjusting the clothing processing device 10 so that the central axis of the outer barrel 200 is above the central axis of the inner barrel 300, the water level of the inner barrel 300 can reach the target water level and the water intake is reduced, thereby achieving a water-saving effect.
[0076] The control method of the clothing processing device provided in the embodiment of the present application is that the inner barrel 300 and the outer barrel 200 of the clothing processing device 10 can perform relative movement in the height direction, and the extension and retraction device 400 is controlled by the clothing processing step currently executed by the clothing processing device to make the washing water in the inner barrel 300 reach the corresponding optimal water level, which can improve the clothing processing effect of the clothing processing device.
[0077] The present application also provides a control device, which is applied to a clothes processing device, such as Figure 1-Figure 4 As shown, the clothes processing device 10 includes a box body 100 and an outer barrel 200, an inner barrel 300 and a telescopic device 400 arranged in the box body 100, the outer barrel 200 is sleeved outside the inner barrel 300, and the telescopic device 400 includes a fixed end 410 and a movable end 420, the fixed end 410 is fixedly connected to the box body 100, and the movable end 420 is suitable for connecting with the outer barrel 200 or the inner barrel 300, and the telescopic device 400 can telescopically make the movable end 420 close to or away from the fixed end 410; for example, please refer to Figure 8 , Figure 8 The control device 20 includes a detection module 21 and a control module 22.
[0078] Among them, the detection module 21 is used to detect the clothing processing steps performed by the clothing processing device; the control module 22 is used to control the telescopic device to extend and retract according to the clothing processing steps to drive the outer barrel and the inner barrel to move relative to each other, thereby changing the relative height of the outer barrel and the inner barrel.
[0079] The control device of the clothing processing device provided in the embodiment of the present application is capable of performing relative movement in the height direction between the inner barrel 300 and the outer barrel 200 of the clothing processing device 10. The extension and retraction of the extension device 400 is controlled by the clothing processing step currently executed by the clothing processing device so that the washing water in the inner barrel 300 reaches the corresponding optimal water level, thereby improving the clothing processing effect of the clothing processing device.
