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 at the same time after the drum rotates to the same 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 excessive drainage, and may even cause the drainage water to overflow outside the laundry treatment device.

[0008] In addition, in the later stage of drainage of the clothing processing equipment, the amount of washing water remaining in the drum is not large, which makes the drainage flow rate smaller. However, at this time, in order to ensure that the drain outlet is open, the drum needs to be driven to rotate at a higher speed, which increases the working energy consumption of the clothing processing equipment.

[0009] In view of this, the present invention is proposed. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide 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 for clothing processing equipment to intelligently regulate the drainage program, thereby achieving the purpose of avoiding drainage overflow.

[0011] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0012] A clothes processing device,

[0013] It includes: a roller,

[0014] There are multiple drainage ports on the drum, each of which is equipped with a centrifugal drainage valve.

[0015] When the drum speed exceeds the set value, the centrifugal drain valve is driven by centrifugal force to open the corresponding drain port.

[0016] The drum speed setting value corresponding to opening the drain port of at least one centrifugal drain valve is different from that of other centrifugal drain valves.

[0017] When the drum speed setting values ​​corresponding to the opening of the drain outlets of two or more centrifugal drain valves are different from those of other centrifugal drain valves, the drum speed setting values ​​corresponding to the opening of the drain outlets of the above two or more centrifugal drain valves can be the same value or different values.

[0018] The plurality of drainage ports mentioned above are two or more, that is, two or more centrifugal drainage valves are provided on the drum.

[0019] Furthermore, the centrifugal drain valve includes:

[0020] Valve core, corresponding to closed drain outlet;

[0021] The closed reset structure applies force to the valve core to close the drain port;

[0022] The centrifugal drive structure rotates together with the drum, and is acted upon by the centrifugal force of the drum to overcome the closing force applied to the valve core by the closing and resetting structure, thereby pulling the valve core to move and open the drain outlet.

[0023] Furthermore, the closing force applied by the closing and resetting structure to the valve core of at least one centrifugal drain valve is different from that of other centrifugal drain valves;

[0024] Preferably, the closed reset structure is a spring in a compressed state, the two ends of the spring are respectively connected to the valve core and the roller, and the compressed spring exerts a driving force on the valve core to move radially outward along the roller and close the drain outlet; the elastic coefficient of the spring of at least one centrifugal drain valve is different from that of other centrifugal drain valves.

[0025] Furthermore, the distance between at least one centrifugal drain valve and the drum axis is different from that between the other centrifugal drain valves;

[0026] Preferably, the drum wall is a special-shaped barrel with different radial dimensions, and a drainage outlet is respectively provided on different sections of the drum wall, and the radial dimensions of each section of the drum wall with the drainage outlet are unequal.

[0027] Further, the mass of the centrifugal drive structure of at least one centrifugal drain valve is different from that of the other centrifugal drain valves;

[0028] Preferably, the centrifugal drive structure includes a centrifugal member connected to the valve core via a lever structure, and the product of the centrifugal member and the distance between the centrifugal member's center of gravity and the lever structure fulcrum of at least one centrifugal drainage valve is different from that of other centrifugal drainage valves.

[0029] Furthermore, the greater the drum speed required to open the centrifugal drain valve of each drain outlet, the smaller the drain outlet aperture.

[0030] Furthermore, at least one drain port is provided at the section with the largest diameter of the drum, and the drum rotation speed required to open the centrifugal drain valve provided at the above drain port is less than or equal to the centrifugal drain valves provided at other drain ports.

[0031] Furthermore, it also includes an outer cylinder, which is sleeved on the outside of the drum and is used to collect water flowing out of the drum from the drain port; the outer cylinder is provided with a water level sensor for detecting the water level height in the outer cylinder.

[0032] The present invention also provides a control method for any of the above-mentioned clothing processing equipment, wherein 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 reduced and the number of drain outlets opened is reduced.

[0033] Furthermore, the specific steps of the drainage control method of the clothes processing equipment are as follows:

[0034] Step S1: The drainage process is started, the drum rotates at the maximum first set value, and the centrifugal drainage valves at each drainage port are opened by the centrifugal force;

[0035] Step S2, detecting the water level in the outer cylinder; if the detected water level in the outer cylinder is greater than the set water level, executing step S3; if not, continuing to execute step S1;

[0036] Step S3: Control the drum speed to decrease to a second set value, the centrifugal drain valves of some drain outlets are closed, and the centrifugal drain valves of some drain outlets continue to remain open due to the centrifugal force.

[0037] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0038] Through the above-mentioned arrangement, the drum of the clothing processing device can drive different numbers of centrifugal drain valves to open at different rotational speeds, so that the clothing processing device can adjust the rotational speed of the drum, thereby adjusting the number of drain outlets of the drum accordingly, thereby achieving the effect of adjusting the drainage flow rate of the hole-free drum of the clothing processing device accordingly.

[0039] 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

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] In this embodiment of the present invention, the drum 3 is provided with multiple drain ports 4, each of which is equipped with a centrifugal drain valve 5. The valve core 6 of each centrifugal drain valve 5 blocks the corresponding drain port 4, so that during normal operation of the laundry processing device, the drain port of the drum is blocked by the valve core, thereby ensuring that the drum forms a sealed water container. At the same time, after the rotation 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 washing water contained in the drum 3 to be discharged outward from the drain port 4, flow into the water collection container outside the drum 3, and then flow out of the laundry processing device through a drain pipe 10 connected to the bottom of the water collection container. The aforementioned multiple drain ports 4 are two or more drain ports 4, so that the drum 3 is provided with two or more centrifugal drain valves 5.

[0054] 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.

[0055] 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.

[0056] like Figures 1 to 4 As shown, in an embodiment of the present invention, the clothes processing device includes: a drum 3, a plurality of drain outlets 4 are provided on the drum 3, and a centrifugal drain valve 5 is provided at each drain outlet 4; 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 rotation speed setting value of the drum 3 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.

[0057] When the drum speed setting values ​​corresponding to the opening of the drain outlets of two or more centrifugal drain valves are different from those of other centrifugal drain valves, the drum speed setting values ​​corresponding to the opening of the drain outlets of the above two or more centrifugal drain valves can be the same value or different values.

[0058] Through the above-mentioned arrangement, the drum of the clothing processing device can drive different numbers of centrifugal drain valves to open at different rotational speeds, so that the clothing processing device can adjust the rotational speed of the drum, thereby adjusting the number of drain outlets of the drum accordingly, thereby achieving the effect of adjusting the drainage flow rate of the hole-free drum of the clothing processing device accordingly.

[0061] like Figure 1 and Figure 2 As shown, in this embodiment, the centrifugal drain valve 5 includes:

[0062] The valve core 6 corresponds to the closed drain port 4;

[0063] The closed reset structure applies a force to the valve core to close the drain port 4;

[0064] 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.

[0065] 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 are made:

[0066] like Figure 1 and Figure 2 As shown, in this embodiment, the closing force applied by the closing and resetting structure to the valve core 6 of at least one centrifugal drainage valve 5 is different from that of other centrifugal drainage valves 5, so that the closing and resetting structures of different centrifugal drainage valves 5 are set differently, so as to achieve the purpose of adjusting the drum 3 speed setting value corresponding to the closing of the valve core 6 of the centrifugal drainage valve 5 accordingly.

[0067] In this embodiment, the closing and resetting structure can be any existing elastic component such as a spring 9, a hydraulic rod, a pneumatic rod, etc. The closing and resetting structures of different centrifugal drain valves can be set to different elastic coefficients, different numbers, etc. For example, the following settings are provided:

[0068] like Figure 1 and Figure 2 As shown, in this embodiment, the closing and resetting structure of the centrifugal drain valve is a spring 9 in a compressed state, and the two ends of the spring 9 are respectively connected to the valve core 6 and the drum 3. 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.

[0069] Example 2

[0070] This embodiment is based on the above embodiment 1 and also has the following technical features:

[0071] like Figure 4 As shown, in this embodiment, in order to achieve different setting values ​​of the drum 3 speed corresponding to opening the drain outlet 4 of different centrifugal drain valves 5, the following settings are made:

[0072] like Figure 4 As shown, in this embodiment, the distance between at least one centrifugal drainage valve 5 and the axis of the drum 3 is different from that of other centrifugal drainage valves 5, so that the valve cores 6 of the centrifugal drainage valves 5 at different distances are subjected to different centrifugal forces when the drum 3 has the same rotational speed, thereby realizing that the centrifugal drainage valves 5 at different positions are opened at different rotational speeds of the drum 3, so that the valve cores 6 of the centrifugal drainage valves 5 at different positions correspond to different setting values ​​of the rotational speed of the drum 3 when they are opened.

[0073] Preferably, in this embodiment, the wall of the drum 3 is a special-shaped barrel with different radial dimensions, at least one drain port 4 is provided on different sections of the wall of the drum 3, and the radial dimensions of the sections of the wall with the drain port 4 are unequal.

[0074] Further preferably, in this embodiment, at least one drain port 4 is provided on the cross section of the maximum radial dimension of the drum 3 to ensure that all water in the drum can be discharged from the drain port, thereby avoiding residual washing water in the drum.

[0075] Example 3

[0076] This embodiment is based on the above-mentioned embodiments 1 and 2 and also has the following technical features:

[0077] like Figure 1 and Figure 3 As shown, in this embodiment, in order to achieve different setting values ​​of the drum 3 speed corresponding to opening the drain outlet 4 of different centrifugal drain valves, the following settings are made:

[0078] like 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 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.

[0079] Preferably, Figure 1 and Figure 3As shown, in this embodiment, the centrifugal drive structure includes a centrifugal member 7, which is connected to the valve core 6 via a lever structure 8. The centrifugal member 7 of at least one centrifugal drainage valve 5 and the product of the distance between the center of gravity of the centrifugal member 7 and the fulcrum of the lever structure 8 are different from those 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.

[0080] Example 4

[0081] This embodiment introduces a clothing processing device. In order to achieve different settings of the drum 3 speed setting values ​​corresponding to different centrifugal drain valves 5 opening the drain outlet 4, the clothing processing device can be set in any one or a combination of the above embodiments one to three.

[0082] Example 5

[0083] This embodiment, based on the above-mentioned embodiments 1 to 4, also has the following technical features:

[0084] In this embodiment, in order to ensure smooth drainage and allow all the washing water in the drum 3 to be discharged, the following settings are made: the apertures of the various drain ports 4 on the drum 3 of the clothes processing equipment are set to be different, and the greater the speed of the drum 3 required to open the centrifugal drain valve 5 of each drain port 4, the smaller the aperture of the drain port 4, so that when the speed of the drum 3 is slowed down, the drainage rate of the drum 3 decreases in an arithmetic progression, and the drainage rate can be guaranteed while effectively preventing drainage overflow.

[0085] like Figure 4 As shown, in this embodiment, at least one drain outlet 4 is provided at the cross-section with the largest diameter of the drum 3. The rotational speed of the drum 3 required to open the centrifugal drain valve 5 provided at the above drain outlet 4 is less than or equal to the centrifugal drain valves 5 provided at other drain outlets 4, so as to ensure that when the clothing processing device executes the drainage program, the drain outlet 4 provided at the cross-section with the largest diameter of the drum 3 is always open, so that all the water in the drum 3 can be discharged.

[0086] In this embodiment, the clothing processing device also includes an outer drum 2, which is mounted on the outside of the drum 3 to form a water collecting container for collecting water flowing out of the drum 3 from the drain outlet 4; the outer drum 2 is provided with a water level sensor for detecting the water level height in the outer drum 2, so as to perform real-time detection of the drainage water level accumulated in the outer drum 2 (not indicated in the accompanying drawings).

[0087] Example 5

[0088] This embodiment introduces a control method for the clothing processing equipment described in any one of the above-mentioned embodiments one to four.

[0094] In this embodiment, a first centrifugal drain valve is installed at the first type of drain outlet, a second centrifugal drain valve is installed at the second type of drain outlet, and an nth centrifugal drain valve is installed at the nth type of drain outlet. When the first centrifugal drain valve is opened at the first type of drain outlet, the corresponding drum speed is a first set speed, when the second centrifugal drain valve is opened at the second type of drain outlet, the corresponding drum speed is a second set speed, and when the nth centrifugal drain valve is opened at the nth type of drain outlet, the corresponding drum speed is an nth set speed. The first set speed is less than the second set speed, and so is less than the nth set speed.

[0095] Preferably, in this embodiment, the first drain opening has a smaller diameter than the second drain opening, and smaller than the nth type of drain opening. Further preferably, at least one nth type of drain opening is located in the cross-section of the drum with the largest diameter, to ensure that all water in the laundry processing drum can be drained.

[0096] Preferably, in this embodiment, the specific steps of the drainage control method of the clothes processing equipment can be as follows:

[0097] Step S1: The drainage process is started, the drum rotates at the maximum first set value, and the centrifugal drainage valves at each drainage port are opened by the centrifugal force;

[0098] Step S2, detecting the water level in the outer cylinder; if the detected value of the water level in the outer cylinder is greater than the first set water level, executing step S3; if not, continuing to execute step S1;

[0099] Step S3: Control the drum speed to decrease to a second set value, so that the centrifugal drain valve of the first type of drain outlet is closed, and the centrifugal drain valves of other drain outlets remain open due to the centrifugal force;

[0100] Step S4, detecting the water level in the outer cylinder; if the detected value of the water level in the outer cylinder is greater than the second set water level, executing step S5; if not, continuing to execute step S3;

[0101] Step S5: Control the drum speed to decrease to a third set value, close the centrifugal drain valves of the first and second type drain outlets, and keep the centrifugal drain valves of other drain outlets open due to the centrifugal force.

[0102] Step Sn, detecting the water level in the outer drum; if the outer drum water level detection value is greater than the nth set water level, the centrifugal drain valves of all drain outlets are closed, and the clothing processing equipment sends a drainage blockage alarm signal.

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.
