Description

Technical Field

[0001] The present invention relates to a clothes processing device in a household appliance, in particular to a clothes processing device with a non-porous drum, and more particularly to a drainage control method of the non-porous drum without dehydration holes. Background Art

[0002] With the improvement of people's living standards, today's washing machines generally integrate some other clothing processing functions, such as: washing and drying machines and dryers with clothing drying function, refreshers with wrinkle removal and ironing functions, etc. These clothing processing equipment have gradually entered the homes of the general public.

[0003] Existing clothes washing equipment can be generally divided into pulsator type, stirring type and drum type. However, no matter which type of clothes washing equipment is used, the clothes are washed by removing stains from the clothes through the action of water and detergent to achieve the effect of washing clothes.

[0004] A drum-type laundry processing device generally includes a housing with an outer tub for containing washing water installed inside, a drum for containing laundry provided inside the outer tub, and a motor and shaft for rotating the drum provided on the back of the outer tub.

[0005] In the aforementioned conventional drum-type laundry processing apparatus, wash water cross-flows between the drum and outer tub during the wash cycle, resulting in a large amount of dirt being retained between the drum exterior and the outer tub. To prevent this contamination of the wash water by this dirt, the applicant previously proposed a non-porous drum-type laundry processing apparatus that combines the inner and outer tubs into one, thus overcoming the problem of dirt remaining between the drum and the outer tub. During drainage, the non-porous drum-type laundry processing apparatus utilizes the centrifugal force of the drum's rotation to open a valve at the drain outlet, allowing the wash water in the drum to flow out of the drain outlet. The drain water then flows into a water collection container for collection and then exits the apparatus through a drain pipe connected to the water collection container.

[0006] However, the valve body provided at the drum drain port of the above-mentioned non-porous drum laundry processing device generally opens or closes the drain port after the drum speed reaches a set value, which has the following problems:

[0007] During the drainage process of the laundry treatment device, especially in the early stage of the drainage process, the laundry treatment device is prone to excessively high water levels in the sump due to rapid drainage, and may even cause the drainage water to overflow outside the laundry treatment device.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a control method and a clothing processing device for a clothing processing device to achieve the purpose of controllable adjustment of the drainage flow rate; in addition, the present invention also provides a control method and a clothing processing device for a clothing processing device to intelligently regulate the drainage program, thereby achieving the purpose of avoiding drainage overflow.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0011] A control method for a clothing processing device, wherein the drum of the clothing processing device is provided with at least one drain outlet, and a centrifugal drain valve is provided at the drain outlet; after the drum rotation speed exceeds a set value, the centrifugal drain valve is driven by centrifugal force to open the drain outlet; when executing a drainage program, the drum operates alternately at a rotation speed greater than or equal to the set value and a rotation speed less than the set value.

[0012] Furthermore, during the drainage process, step s1 and step s2 are performed alternately;

[0013] Step s1: During the set time t1, the drum rotates at a speed greater than or equal to the set value;

[0014] Step s2: During the set time t2, the drum rotates at a speed less than the set value.

[0015] Furthermore, during the drainage process, each time steps s1 and s2 are executed, the required t1 and t2 are variables;

[0016] During the drainage process, the time t1 required for each execution of step s1 increases successively, and the time t2 required for each execution of step s2 decreases successively;

[0017] Preferably, the increment of t1 and the decrement of t2 are both the same set value.

[0018] Furthermore, when executing step s2, the drum rotates forward and reverse at a speed lower than a set value and at a set rotation-stop ratio, stirring the load in the drum to distribute it evenly and / or defoaming the washing water in the drum.

[0019] Furthermore, in the initial stage of drainage, the drum rotates alternately at a speed greater than or equal to a set value and a speed less than the set value;

[0020] In the later stage of drainage, the drum continues to rotate at a speed greater than the set value.

[0021] Furthermore, during the drainage process, the drum is controlled to rotate at a speed greater than a maximum set value and lower than a minimum set value, and some drainage ports are controlled to be opened and some drainage ports are controlled to be closed;

[0022] Preferably, in the initial stage of drainage, the drum is controlled to rotate alternately at a speed n1 which is less than the maximum setting value and greater than or equal to the minimum setting value, and a speed n0 which is less than the minimum setting value;

[0023] In the middle of drainage, the drum is controlled to continuously run at a speed n2 greater than or equal to the minimum set value;

[0024] In the later stage of drainage, the drum is controlled to continuously run at a speed n3 greater than or equal to the maximum set value.

[0025] Furthermore, the drainage water flowing out of the drum from the drainage port flows into the outer drum; during the drainage process, the water level in the outer drum is monitored; when the liquid level detection value is higher than the set value, the drum speed is controlled to drop below the set value; when the level detection value is lower than the set value, the drum speed is controlled to rise to the set value or above.

[0026] Furthermore, when the duration of the drum rotation speed dropping below the set value exceeds the set value t, it is determined that the drainage is blocked, the drum rotation is stopped, and an alarm prompting the drainage blockage is issued.

[0027] Furthermore, when the water level in the outer drum reaches the maximum water level, it is determined that the drainage is blocked, the rotation of the drum is stopped, and an alarm prompting the drainage blockage is issued.

[0028] The present invention also provides a clothes processing device, which adopts any of the above-mentioned control methods for clothes processing devices.

[0029] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0030] Through the above-mentioned arrangement, the opening and closing state of the drain outlet of the drum of the clothing processing device is controlled in the form of an adjustable speed, so as to adjust the opening and closing time ratio of the drum drain outlet accordingly, thereby achieving the effect of controlling the drainage flow rate of the hole-free drum of the clothing processing device, thereby avoiding the occurrence of excessively rapid drainage water flow in the drum of the clothing processing device, resulting in drainage overflow, etc.

[0031] At the same time, the present invention has a simple structure, a concise method and a significant effect, and is suitable for promotion and use.

DETAILED DESCRIPTION

[0043] 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.

[0044] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections 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.

[0046] like Figures 1 to 4 As shown, an embodiment of the present invention introduces a clothing processing device, which includes a drum 3. The drum 3 is a barrel-shaped structure without a normally open through hole. When the clothing processing device executes a clothing washing program, the drum can independently hold washing water and can rotate. The rotational force is used to beat the clothes and water to achieve the effect of washing the clothes in the drum, avoiding the problem that the washing water cross-flows inside and outside the drum 3 during the operation of the clothing processing device, causing the washing water to be contaminated by dirt and bacteria accumulated outside the drum and unable to thoroughly clean the clothes.

[0047] In this embodiment of the present invention, the drum 3 is provided with at least one drain port 4, each of which is fitted with a centrifugal drain valve 5. A valve core 6 of each centrifugal drain valve 5 blocks the corresponding drain port 4. During normal operation of the laundry processing apparatus, the drain port of the drum is blocked by the valve core, thereby ensuring that the drum forms a sealed water container. Simultaneously, when the speed of the drum 3 reaches a set value, the valve core 6 is driven by centrifugal force to open the corresponding drain port 4, allowing the wash water contained in the drum 3 to be discharged outward from the drain port 4 into a water collection container outside the drum 3. The water then flows out of the laundry processing apparatus through a drain pipe 10 connected to the bottom of the water collection container.

[0048] In the embodiment of the present invention, the water collection container is an independent component, which can be other water collection tanks arranged below or on the periphery of the drum, or can be formed by the existing outer cylinder 2 (such as Figures 1 to 4 shown) directly constitutes, etc.

[0049] In the embodiment of the present invention, the drum 3 is rotatably mounted on a support member, and the support member may be an independent member or other member; preferably, Figures 1 to 4 As shown, in the embodiment of the present invention, the support member is an outer cylinder 2 which is sleeved on the outside of the drum. The outer cylinder 2 is telescopically installed in the shell 1 of the clothing processing device through a shock-absorbing support member. The outer cylinder 2 constitutes a water collection container for collecting the drainage water flowing out of the open drain port 4 of the drum.

[0050] like Figures 5 to 7As shown, in an embodiment of the present invention, the control method of the clothing processing device is as follows: at least one drain outlet is provided on the drum of the clothing processing device, and a centrifugal drain valve is provided at the drain outlet; after the drum speed exceeds the set value, the centrifugal drain valve is driven by centrifugal force to open the drain outlet, and when executing the drainage program, the drum operates alternately at a speed greater than or equal to the set value and a speed less than the set value.

[0051] Through the above-mentioned arrangement, the opening and closing state of the drain outlet of the drum of the clothing processing device is controlled in the form of an adjustable speed, so as to adjust the opening and closing time ratio of the drum drain outlet accordingly, thereby achieving the effect of controlling the drainage flow rate of the hole-free drum of the clothing processing device, thereby avoiding the occurrence of excessively rapid drainage water flow in the drum of the clothing processing device, resulting in drainage overflow, etc.

[0052] Example 1

[0053] like Figure 5 As shown, this embodiment introduces a control method for a clothing processing device, wherein at least one drain outlet is provided on the drum of the clothing processing device, and a centrifugal drain valve is provided at the drain outlet; after the drum speed exceeds the set value, the centrifugal drain valve is driven by centrifugal force to open the drain outlet, and when the drainage program is executed, the drum rotates at a speed greater than or equal to the set value, and when it is detected that the drainage water flow in the outer drum is too high, the drum speed is controlled to be reduced to below the set value to close the drain outlet and avoid the occurrence of drainage overflow due to excessive drainage.

[0054] In this embodiment, the drainage water flowing out of the drum from the drain outlet flows into the outer drum; during the drainage process of the clothing processing equipment, the water level in the outer drum is monitored; when the liquid level detection value is higher than the set value, the drum speed is controlled to drop below the set value; when the level detection value is lower than the set value, the drum speed is controlled to increase to the set value or above.

[0055] In this embodiment, when the drum rotation speed drops below the set value for a duration exceeding the set value t, it is determined that the drainage is blocked, the drum rotation is stopped, and an alarm prompting drainage blockage is issued.

[0056] In this embodiment, when the water level in the outer drum reaches the maximum water level, it is determined that the drainage is blocked, the rotation of the drum is stopped, and an alarm prompting the drainage blockage is issued.

[0057] Preferably, Figure 5 As shown, in this embodiment, the specific steps of the laundry processing device performing the drainage process are as follows:

[0058] Step s1: Drainage starts. The drum rotates at a speed greater than the set value. The centrifugal drain valve opens the drain port and the drum starts draining.

[0059] Step s2, monitoring the water level in the outer cylinder; if the water level detection value in the outer cylinder exceeds the set water level, executing step s3; if the water level detection value in the outer cylinder is lower than the set water level, continuing to execute step s1;

[0060] Step s3: the drum rotates at a speed lower than the set value, or stops rotating;

[0061] Step s4, determining whether the duration of the water level detection value in the outer tube exceeding the set water level exceeds the set time t; if so, executing step s5; if not, executing step s2;

[0062] Step s5: Determine whether the drainage is blocked, stop the drum from rotating, and issue a drainage blockage alarm.

[0063] Example 2

[0064] like Figure 6 As shown, this embodiment introduces a control method for a clothing processing device, wherein at least one drain outlet is provided on the drum of the clothing processing device, and a centrifugal drain valve is provided at the drain outlet; after the drum rotation speed exceeds the set value, the centrifugal drain valve is driven by centrifugal force to open the drain outlet, and when executing the drainage program, the drum operates alternately at a rotation speed greater than or equal to the set value and a rotation speed less than the set value, so as to reduce the opening time period of the drain outlet, slow down the drainage water flow, and avoid the occurrence of drainage overflow in the non-porous drum.

[0065] like Figure 6 As shown, in this embodiment, during the drainage process of the clothes processing device, step s1 and step s2 are performed alternately;

[0066] Step s1: During the set time t1, the drum rotates at a speed greater than or equal to the set value;

[0067] Step s2: During the set time t2, the drum rotates at a speed less than the set value.

[0068] In this embodiment, during the drainage process, each time steps s1 and s2 are executed, the required t1 and t2 are variables;

[0069] During the drainage process, the time t1 required for each execution of step s1 increases successively, and the time t2 required for each execution of step s2 decreases successively;

[0070] Preferably, the increment of t1 and the decrement of t2 are both the same set value.

[0071] In this embodiment, when executing step s2, the drum rotates forward and reverse at a speed lower than the set value and at a set rotation-stop ratio, stirring the load in the drum to distribute it evenly and / or defoaming the washing water in the drum.

[0072] In this embodiment, at the initial stage of drainage, the drum rotates alternately at a speed greater than or equal to a set value and a speed less than the set value;

[0073] In the later stage of drainage, the drum continues to rotate at a speed greater than the set value.

[0074] Example 3

[0075] This embodiment introduces a control method for a clothing processing device, wherein at least one drain outlet is provided on the drum of the clothing processing device, and a centrifugal drain valve is provided at the drain outlet; after the drum rotation speed exceeds a set value, the centrifugal drain valve is driven by centrifugal force to open the drain outlet; when executing the drainage program, the drum rotates at a speed greater than or equal to the set value, and the drum rotation speed is slowed down when the drainage is too fast, so that at least part of the drain outlet of the drum is closed, thereby achieving the purpose of slowing down the drainage flow rate and preventing the drainage of the clothing processing device from overflowing.

[0076] like Figures 1 to 4 As shown, in this embodiment, the clothing processing device includes: a drum 3, a plurality of drain outlets 4 are provided on the drum 3, and each drain outlet 4 is provided with a centrifugal drain valve 5; after the rotation speed of the drum 3 exceeds the set value, the centrifugal drain valve 5 is driven by centrifugal force to open the corresponding drain outlet 4; the drum 3 rotation speed setting value corresponding to the opening of the drain outlet 4 by at least one centrifugal drain valve 5 is different from that of other centrifugal drain valves 5.

[0077] In this embodiment, during the drainage process, the drum is controlled to rotate at a speed greater than a maximum set value and lower than a minimum set value, and some drainage outlets are controlled to be opened and some drainage outlets are controlled to be closed.

[0078] In this embodiment, the drum is provided with two or more types of drain outlets, and the drum speed setting value corresponding to the opening of the centrifugal drain valve of each type of drain outlet is different, the minimum speed setting value is the minimum setting value, and the maximum speed setting value is the maximum setting value.

[0079] like Figure 7 As shown, in this embodiment, the specific steps of the drainage process of the clothes processing device are as follows:

[0080] At the initial stage of drainage, the drum is controlled to rotate alternately at a speed n1 which is less than the maximum setting value and greater than or equal to the minimum setting value, and a speed n0 which is less than the minimum setting value;

[0081] In the middle of drainage, the drum is controlled to continuously run at a speed n2 greater than or equal to the minimum setting value and less than or equal to the maximum setting value;

[0082] In the later stage of drainage, the drum is controlled to continuously run at a speed n3 greater than or equal to the maximum set value.

[0083] like Figures 1 to 4 As shown, in this embodiment, the centrifugal drain valve 5 includes:

[0084] The valve core 6 corresponds to the closed drain port 4;

[0085] The closed reset structure applies a force to the valve core to close the drain port 4;

[0086] The centrifugal drive structure rotates together with the drum 3 and overcomes the closing force applied to the valve core 6 by the closing and resetting structure under the centrifugal force of the drum 3, thereby pulling the valve core 6 to move and open the drain port 4.

[0087] The above-mentioned closing and resetting structure can be any one or combination of the elastic components such as spring, hydraulic rod, pneumatic rod, etc., for example: Figure 2 and Figure 3 As shown, the closed reset structure consists of a spring 9 in a compressed state, with both ends of the spring 9 connected to the valve core 6 and the drum 3 respectively. The compressed spring 9 applies a driving force to the valve core 6 to move radially outward along the drum 3 and close the drain port 4; the elastic coefficient of the spring 6 of at least one centrifugal drain valve 5 is different from that of other centrifugal drain valves 5.

[0088] like Figures 1 to 4 As shown, the above-mentioned centrifugal drive structure can be set as follows: it includes a centrifugal member 7, which is connected to the valve core 6 via a lever structure 8. The product of the centrifugal member 7 of at least one centrifugal drainage valve 5 and the distance between the center of gravity of the centrifugal member 7 and the fulcrum of the lever structure 8 is different from that of other centrifugal drainage valves 5; that is, the mass of the centrifugal member 7 of different centrifugal drainage valves 5, and / or the distance between the centrifugal member 7 and the fulcrum are set to be different, so that when the drum 3 has the same speed, the opening force applied by the centrifugal member 7 to the valve core 6 is different, thereby achieving different settings of the drum 3 speed setting values ​​corresponding to the opening of the valve core 6 of different centrifugal drainage valves 5.

[0089] In this embodiment, in order to achieve different rotation speed setting values ​​of the drum 3 corresponding to opening the drain outlet 4 of different centrifugal drain valves 5, the following settings can be made:

[0090] like Figure 1 and Figure 2 As shown, in this embodiment, the closing force exerted by the closing and resetting structure on the valve core 6 of at least one centrifugal drain valve 5 provided on the drum 3 is different from that on other centrifugal drain valves 5, so that the closing and resetting structures of different centrifugal drain valves 5 are set differently, thereby achieving the purpose of adjusting the set value of the drum 3 speed corresponding to the closing of the valve core 6 of the centrifugal drain valve 5;

[0091] and / or, such as Figure 4As shown, in this embodiment, at least one centrifugal drain valve 5 is provided on the drum 3 at a different distance from the drum axis than other centrifugal drain valves 5, so that the valve cores 6 of the centrifugal drain valves 5 at different distances are subjected to different centrifugal forces at the same speed of the drum 3, thereby achieving the opening of the centrifugal drain valves 5 at different positions at different speeds of the drum 3, so that the valve cores 6 of the centrifugal drain valves 5 at different positions correspond to different speed settings of the drum 3;

[0092] and / or, such as Figure 1 and Figure 3 As shown, in this embodiment, the mass of the centrifugal drive structure of at least one centrifugal drain valve 5 provided on the drum 3 is different from that of other centrifugal drain valves 5, so that the centrifugal drive structures of different centrifugal drain valves 5 apply different opening forces to the valve core 6 when the drum 3 has the same rotational speed, thereby achieving the effect of different drum 3 rotational speed setting values ​​corresponding to the opening of the centrifugal drain valves 5 at different drain outlets 4.

[0093] 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 with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. 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.
