Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically providing a clothing processing device and its control method. Background Technology

[0002] In today's daily life, with the continuous development and progress of society, people are paying more attention to their personal hygiene. Consequently, people wash their clothes more frequently, making fully automatic washing machines increasingly convenient and an indispensable household appliance. Currently, there are two common types of washing machines: top-loading washing machines and front-loading washing machines. Top-loading washing machines have a pulsator structure at the bottom of the inner drum. During the washing process, the pulsator rotates in both directions, creating vortices in the water flow. This tumbling of the clothes with the water flow generates friction, achieving the washing effect. Front-loading washing machines, on the other hand, use the mechanical work of a motor to rotate the drum. The clothes are repeatedly lifted to higher places and then tumbled down within the drum, and this repeated motion achieves the washing effect.

[0003] Compared to outerwear and trousers, smaller items like underwear are washed more frequently. Traditional washing machines (such as top-loading or front-loading washing machines) have a large capacity, so washing small items frequently would be wasteful of resources. Furthermore, because small items are usually small in size, the washing results may not meet expectations.

[0004] In addition, when people travel to other places for business or tourism, they usually stay in local hotels. Although some hotels provide washing machine services, considering that hotel washing machines are public facilities, they are subject to various factors such as the frequency, time and intensity of disinfection by the management of the washing machines. As a result, the washing machines may contain germs, which may contaminate clothes and endanger human health. Therefore, it is difficult for people to use them with peace of mind.

[0005] Currently, small washing machines have been developed on the market specifically for washing small items of clothing. They use a flexible drum inside, and an external drive structure rubs and kneads the flexible drum at a fixed position to achieve the purpose of gentle washing. However, this kind of long-term friction at a fixed position will cause serious wear and tear on the flexible drum, and because the washing area is not comprehensive enough, it cannot achieve the ideal washing effect.

[0006] Therefore, there is a need in the field to propose a new garment processing device to solve the above problems. Summary of the Invention

[0007] To address the aforementioned problems in the prior art, namely the issues of easy damage to the flexible tub and unsatisfactory washing effect in existing garment processing equipment with flexible tubs, the present invention provides a garment processing device.

[0016] In a specific embodiment of the above-mentioned garment processing equipment, the driving assembly further includes a compression driving component, which is fixedly mounted on the rotating bracket. One end of the compression rod is fixedly connected to the output end of the compression driving component so that the compression rod can compress the flexible barrel.

[0017] In a specific embodiment of the above-mentioned clothing processing equipment, the flexible tub includes a flexible sidewall and a rigid base, wherein the flexible sidewall is snapped onto the rigid base.

[0018] In a specific embodiment of the above-mentioned garment processing equipment, a rotating shaft support is also provided at the bottom of the rigid chassis. The output shaft of the rotating drive motor is inserted into the rotating shaft support and can rotate relative to the rotating shaft support.

[0019] In a specific embodiment of the above-mentioned clothing processing equipment, a heating tube is also provided below the rigid base.

[0020] In a specific embodiment of the above-mentioned clothing processing equipment, a water inlet pipe and a drain pipe are also provided on the flexible washing tub, and a pump body is also provided on the water inlet pipe and / or the drain pipe.

[0021] In a specific embodiment of the above-mentioned garment processing equipment, the drive assembly includes a rotary drive motor and a rotary bracket;

[0022] The rotary drive motor is located at the center of the bottom of the flexible barrel;

[0023] The rotating bracket is fixedly mounted on the output shaft of the rotating drive motor;

[0024] At least two extrusion rods are provided and are centrally symmetrically arranged around the outer wall of the flexible barrel. One end of each extrusion rod is connected to the rotating bracket via a lifting device.

[0025] The present invention also proposes a control method for a garment processing device, the garment processing device including a flexible drum and a kneading and squeezing device disposed on the outside of the flexible drum, the kneading and squeezing device including a squeezing rod, a kneading wheel and a drive assembly;

[0026] The drive assembly is configured to drive the extrusion rod to rotate around the outer wall of the flexible barrel;

[0027] The kneading wheel is rotatably mounted on the extrusion rod and is configured to knead the outer wall of the flexible barrel, and can also reciprocate along the direction of the extrusion rod.

[0028] The drive assembly includes a rotary drive motor and a rotary bracket;

[0029] The rotary drive motor is located at the center of the bottom of the flexible barrel;

[0030] The rotating bracket is fixedly mounted on the output shaft of the rotating drive motor;

[0031] At least two extrusion rods are provided and are centrally symmetrically arranged around the outer wall of the flexible barrel, with one end of each extrusion rod fixedly connected to the rotating bracket;

[0032] The extrusion rod is provided with a first thread, and the kneading wheel is provided with a second thread. The kneading wheel is sleeved on the extrusion rod, and the first thread and the second thread are connected in a mating manner.

[0033] The control method includes:

[0034] Control the rotary drive motor to rotate forward;

[0035] When the kneading wheel reaches the limit stop, the rotation drive motor is controlled to reverse.

[0036] In the above technical solution of the present invention, the garment processing equipment of the present invention includes a flexible tub and a kneading and squeezing device. The flexible tub includes a flexible sidewall and a rigid base. The kneading and squeezing device includes a squeezing rod, a kneading wheel and a driving assembly. The squeezing rod is parallel to the axial direction of the flexible tub and is centrally symmetrically arranged on the outside of the flexible tub. The kneading wheel is rotatably sleeved on the squeezing rod and can knead the flexible sidewall of the flexible tub. While rotating, the kneading wheel also moves up and down along the direction of the squeezing rod. Driven by the driving device, the squeezing rod rotates around the flexible tub on the outside of the flexible tub. Due to the friction between the kneading wheel and the flexible sidewall, the kneading wheel will rotate relative to the squeezing rod and roll along the flexible sidewall. At the same time, it moves up and down along the direction of the squeezing rod with the driving direction of the driving device. Therefore, the kneading wheel can knead the flexible sidewall while rolling with the squeezing rod and can also knead the flexible sidewall in the up and down direction. At this time, the kneading wheel is making a sinusoidal rolling motion on the flexible sidewall relative to the flexible sidewall.

[0037] During the sinusoidal motion of the rubbing wheel rolling on the flexible sidewall, the rubbing wheel can repeatedly rub the flexible tub at multiple positions. Compared with existing clothing processing equipment that rubs the flexible tub at a fixed position for a long time, the clothing processing equipment of the present invention has a larger rolling area, which can improve the washing effect. At the same time, the repeated rolling and multiple-position rubbing also reduces the wear on the flexible tub, solving the problems of easy damage to the flexible tub and unsatisfactory washing effect of existing clothing processing equipment with flexible tubs.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] The specific embodiments of the present invention are described below.

[0051] like Figure 1As shown, the garment processing device 1 of the present invention includes a flexible tub 11 and a kneading and squeezing device 12 disposed on the outside of the flexible tub 11. The structures of these two parts will be described below.

[0052] First refer to Figure 1 The structure of the flexible tub 11 of the garment processing device 1 of the present invention will be described as follows: Figure 1 As shown, the flexible tub 11 includes a water inlet pipe 113, a drain pipe 114, a flexible sidewall 111, and a rigid base 112 disposed below the flexible sidewall 111. One end of the water inlet pipe 113 and the drain pipe 114 are respectively disposed on the flexible sidewall 111. Correspondingly, the flexible sidewall 111 is also provided with openings adapted to the water inlet pipe 113 and the drain pipe 114. A flange 1123 is provided on the periphery of the rigid base 112. A clamp 1124 is provided on the outer side of the flange 1123. The size of the clamp 1124 is set so that the flexible sidewall 111 can be sealed and clamped onto the flange 1123 of the rigid base 112. A rotating shaft support seat 1121 is also provided at the bottom of the rigid base 112. The above is the specific structure of the flexible tub 11 of the clothing processing device 1 of the present invention. Next, the structure of the kneading and squeezing device 12 on the outside of the flexible tub 11 will be described.

[0053] See next. Figure 1 , Figure 2 The structure of the kneading and squeezing device 12 of the garment processing equipment 1 of the present invention will be described as follows: Figure 1 As shown, the kneading and squeezing device 12 includes a rotary drive motor 1231 and a rotary bracket 1232. The rotary drive motor 1231 is located at the center of the bottom of the flexible barrel 11. The output shaft 12311 of the rotary drive motor 1231 is inserted into the rotary shaft support 1121 and can rotate relative to the rotary shaft support 1121. The rotary bracket 1232 is fixedly mounted on the output shaft 12311 of the rotary drive motor 1231, so that the rotary bracket 1232 can rotate with the rotation of the output shaft 12311. Meanwhile, the kneading and squeezing device 12 also includes squeezing rods 121 and kneading wheels 122. There are at least two squeezing rods 121, arranged parallel to the axial direction of the flexible barrel 11 and symmetrically positioned on the outer side of the flexible barrel 11. One end of each squeezing rod 121 is fixedly connected to the outer side of the rotating bracket 1232. The kneading wheel 122 is rotatably mounted on the squeezing rod 121 and can knead the outer wall of the flexible barrel 11. While rotating relative to the squeezing rod 121, the kneading wheel 122 also moves up and down reciprocally along the direction of the squeezing rod 121. Figure 2 As shown, a first thread 1212 is provided on the extrusion rod 121, and a second thread 1221 is provided on the kneading wheel 122, and the first thread 1212 and the second thread 1221 are connected in a mating manner.

[0054] In the above-described embodiment, the rotary drive motor 1231 drives the output shaft 12311 to rotate. The output shaft 12311 transmits power to the rotary bracket 1232, causing the rotary bracket 1232 to rotate as well. Since the extrusion rod 121 is fixedly connected to the rotary bracket 1232, the extrusion rod 121 also rotates with the rotary bracket 1232 around the outside of the flexible barrel 11. At this time, the kneading wheel 122, which is sleeved on the extrusion rod 121, is driven by the extrusion rod 121 and also rotates around the outside of the flexible barrel 11 along with the extrusion rod 121. Simultaneously, since the kneading wheel 122 can knead the outer wall of the flexible barrel 11... There is friction between the kneading wheel 122 and the flexible sidewall 111. Therefore, while the kneading wheel 122 rotates around the flexible sidewall 111 with the extrusion rod 121, it also rotates relative to the extrusion rod 121 and rolls on the flexible sidewall 111. Moreover, during the rotation of the kneading wheel 122 relative to the extrusion rod 121, the second thread 1221 on the kneading wheel 122 and the first thread 1212 on the extrusion rod 121 mesh with each other. The kneading wheel 122 moves up and down along the direction of the extrusion rod 121. Thus, the kneading wheel 122 rolls on the outer sidewall of the flexible barrel 11 in a sinusoidal motion, kneading the flexible sidewall 111.

[0055] The advantage of the above-described embodiment is that, during the process of the rubbing wheel 122 rolling on the flexible sidewall 111 in a sinusoidal motion, the rubbing wheel 122 can rub the flexible tub 11 repeatedly at multiple positions. Compared with the existing garment processing equipment 1 that rubs the flexible sidewall 111 in a fixed position for a long time, the garment processing equipment 1 of the present invention can improve the washing effect while the rolling and reciprocating multi-position rubbing also reduces the wear on the flexible tub 11, thus solving the problems of easy damage to the flexible tub 11 and unsatisfactory washing effect of the existing garment processing equipment 1 with a flexible tub 11.

[0056] Regarding the first thread 1212 and the second thread 1221, those skilled in the art will understand that although the first thread 1212 and the second thread 1221 mentioned above are ordinary drive threads for mating connection, this is not the only connection method. When necessary, those skilled in the art can choose other threaded connection methods, such as threads for the drive form of a lead screw nut, etc. These changes are all forms of mating connection between the extrusion rod 121 and the kneading wheel 122 through threaded connection, and are therefore included within the protection scope of this invention.

[0057] The first embodiment of the present invention has now been fully described. Some preferred embodiments of the present invention will now be described.

[0058] In a preferred real-time configuration, a heating tube 1122 is also provided below the rigid chassis 112. The heating tube 1122 is made of a thin metal tube wound together and has an electric heating wire inside. Flame-retardant materials such as magnesium oxide powder are filled into the tube to encapsulate and fix the electric heating wire in the middle of the tube so that it does not contact the tube wall. A self-resetting thermal circuit breaker and a thermal fuse are respectively installed at both ends of the heating tube 1122.

[0059] The advantages of the above-described embodiment are that by transferring the heat from the heating element 1122 to the rigid chassis 112, which directly acts on the clothes to be washed in the flexible tub 11, the washing effect of the clothes is enhanced. This direct heat conduction method avoids heat dissipation and improves the efficiency of the clothing processing device 1. Specifically, the heat emitted by the heating wire is transferred to the heating element 1122 after being buffered by the insulating material. The insulating material ensures that the temperature of the heating element 1122 will not be too high and burn out the parts. Furthermore, a self-resetting thermal circuit breaker and a thermal fuse are provided at both ends of the heating element 1122. This setting ensures that the clothing processing device 1 of the present invention will not suffer irreparable damage due to accidents such as short circuits or overloads, thus providing protection for the life and property safety of the user.

[0060] In a preferred embodiment, an inlet pump 1131 is provided in the inlet pipe 113, and a drain pump 1141 is provided in the drain pipe 114.

[0061] The advantages of the above-described embodiments are that the water inlet pump 1131 and the drain pump 1141 can realize the fully automatic water inlet and drain functions. Furthermore, under the action of the pumps, the clothing processing equipment 1 can suck the entire flexible tub 11 into a deflated state to achieve complete drainage, thus avoiding the problem of residual sewage after washing due to incomplete drainage, which could lead to bacterial growth.

[0062] In a preferred real-time mode, limit stops 1211 are also provided at the upper and lower ends of the compression rod 121.

[0063] The advantage of the above-described embodiment is that when the kneading wheel 122 moves along the direction of the extrusion rod 121 to the end of the extrusion rod 121, the limit stops 1211 at the upper and lower ends of the extrusion rod 121 can ensure that the kneading wheel 122 will not detach from the extrusion rod 121 and fall off. At the same time, when the kneading wheel 122 moves to the limit stop 1211, it can also serve as a trigger signal to control the rotation drive motor 1231 to reverse, thereby realizing the kneading wheel 122 to move up and down along the extrusion rod 121, and thus realizing multi-position kneading of the flexible barrel 11.

[0064] In a preferred real-time mode, the drive assembly 123 further includes a compression drive component 1233, which is fixedly mounted on the rotating bracket 1232. One end of the compression rod 121 is fixedly connected to the output end of the compression drive component 1233, so that the compression rod 121 can compress the flexible barrel 11.

[0065] When the above-described implementation method is adopted, such as Figure 1 and Figure 3 As shown, a squeezing drive component 1233 (such as a hydraulic cylinder) is provided on the rotating bracket 1232. When the garment processing equipment 1 needs to work, the squeezing drive component 1233 retracts along the rotating bracket 1232 toward the rotating drive motor 1231. At this time, the squeezing rod 121 fixed on the squeezing drive component 1233, together with the kneading wheel 122 provided on the squeezing rod 121, also moves toward the flexible sidewall 111 so that the kneading wheel 122 on the squeezing rod 121 can squeeze the flexible barrel 11 to achieve the kneading function. When the garment processing equipment 1 finishes working, the squeezing drive component 1233 moves away from the rotating drive motor 1231 along the rotating bracket 1232. At this time, the squeezing rod 121 and the kneading wheel 122 also move away from the flexible sidewall 111.

[0066] The advantage of the above-described embodiment is that when the garment processing equipment 1 needs to work, the extrusion drive component 1233 can move the extrusion rod 121 and the kneading wheel 122 to a designated position to start working. When the garment processing equipment 1 does not need to work, the extrusion drive component 1233 will reset the extrusion rod 121 and the kneading wheel 122, thereby moving the kneading wheel 122 away from the flexible sidewall 111 and avoiding damage caused by long-term friction and extrusion on the flexible sidewall 111.

[0067] Regarding the extrusion drive component 1233, those skilled in the art will understand that although the extrusion drive component 1233 mentioned above is a hydraulic cylinder, it is not the only option. Those skilled in the art can also choose a pneumatic cylinder, a telescopic rod, etc. As long as it is a conventional component that can perform the above-mentioned positioning and resetting operation of the kneading wheel 122 and the extrusion rod 121, it does not exceed the inventive principle of the present invention, and therefore it is within the protection scope of the present invention.

[0068] The present invention also provides a control method for a garment processing device 1. The garment processing device 1 includes a flexible tub 11 and a kneading and squeezing device 12 disposed on the outside of the flexible tub 11. The kneading and squeezing device 12 includes a squeezing rod 121, a kneading wheel 122 and a drive assembly 123.

[0069] The drive assembly 123 is configured to drive the extrusion rod 121 to rotate around the outer wall of the flexible barrel 11;

[0070] The kneading wheel 122 is rotatably mounted on the extrusion rod 121 and is configured to knead the outer wall of the flexible barrel 11 and to reciprocate along the direction of the extrusion rod 121.

[0071] The drive assembly 123 includes a rotary drive motor 1231 and a rotary bracket 1232;

[0072] The rotary drive motor 1231 is located at the center of the bottom of the flexible barrel 11;

[0073] The rotating bracket 1232 is fixedly mounted on the output shaft 12311 of the rotating drive motor 1231;

[0074] At least two extrusion rods 121 are provided and are centrally symmetrically arranged around the outer wall of the flexible barrel 11. One end of the extrusion rod 121 is fixedly connected to the rotating bracket 1232.

[0075] The extrusion rod 121 is provided with a first thread 1212, and the kneading wheel 122 is provided with a second thread 1221. The kneading wheel 122 is sleeved on the extrusion rod 121, and the first thread 1212 and the second thread 1221 are connected in a mating manner.

[0076] Control methods include:

[0077] S01, Control the rotary drive motor 1231 to rotate forward;

[0078] S02. When the kneading wheel 122 reaches the limit stop 1211, control the rotation drive motor 1231 to reverse.

[0079] With the above control method, the user only needs to press the switch, and the clothing processing device 1 of the present invention can automatically and repeatedly perform multi-directional washing on the clothes in the flexible tub 11. The washing effect is good, the operation is simple, and at the same time, it will not cause great wear and tear on the flexible tub 11, which significantly improves the user experience.

[0080] The preferred embodiments of the present invention have been described above. Next, the second embodiment of the present invention will be described.

[0081] In the second embodiment of the present invention, as Figure 4 As shown, the garment processing device 1 of the present invention includes a flexible tub 11 and a kneading and squeezing device 12 disposed on the outside of the flexible tub 11. The structures of these two parts will be described below.

[0082] See Figure 4The flexible tub 11 includes a water inlet pipe 113, a drain pipe 114, a flexible sidewall 111, and a rigid base 112 disposed below the flexible sidewall 111. One end of the water inlet pipe 113 and the drain pipe 114 are respectively disposed on the flexible sidewall 111. Correspondingly, the flexible sidewall 111 is also provided with openings adapted to the water inlet pipe 113 and the drain pipe 114. A flange 1123 is provided on the periphery of the rigid base 112. A clamp 1124 is provided on the outer side of the flange 1123. The size of the clamp 1124 is set so that the flexible sidewall 111 can be snapped onto the flange 1123 of the rigid base 112. A rotating shaft support seat 1121 is also provided at the bottom of the rigid base 112. The above is the specific structure of the flexible tub 11 of the clothing processing device 1 of the present invention. Next, the structure of the kneading and squeezing device 12 on the outside of the flexible tub 11 will be described.

[0083] Continue reading Figure 4 The structure of the kneading and squeezing device 12 of the garment processing equipment 1 of the present invention will be described as follows: Figure 4 As shown, the kneading and squeezing device 12 includes a rotary drive motor 1231 and a rotary bracket 1232. The rotary drive motor 1231 is located at the bottom center of the flexible barrel 11. The output shaft 12311 of the rotary drive motor 1231 is inserted into the rotary shaft support 1121 and can rotate relative to the rotary shaft support 1121. The rotary bracket 1232 is fixedly mounted on the output shaft 12311 of the rotary drive motor 1231 so that the rotary bracket 1232 can rotate with the rotation of the output shaft 12311. At the same time, the kneading and squeezing device 12 also includes a squeezing rod 121 and a kneading wheel 122. There are at least two squeezing rods 121, which are parallel to the axial direction of the flexible barrel 11 and centrally symmetrically arranged on the outside of the flexible barrel 11. One end of the squeezing rod 121 is connected to the outside of the rotary bracket 1232 through a lifting device 124. The kneading wheel 122 is rotatably mounted on the squeezing rod 121 and can knead the outer wall of the flexible barrel 11.

[0084] In the above-described embodiment, the rotary drive motor 1231 operates to drive the output shaft 12311 to rotate. The output shaft 12311 transmits power to the rotating bracket 1232, causing the rotating bracket 1232 to rotate together. Since the extrusion rod 121 is fixedly connected to the rotating bracket 1232, the extrusion rod 121 also rotates with the rotating bracket 1232 around the outside of the flexible barrel 11. At this time, the kneading wheel 122, which is provided on the extrusion rod 121, is driven by the extrusion rod 121 and also rotates around the outside of the flexible barrel 11 with the extrusion rod 121. Simultaneously, due to the kneading... The roller 122 can knead the outer wall of the flexible barrel 11. There is friction between the kneading roller 122 and the outer wall of the flexible barrel 11. Therefore, while the kneading roller 122 rotates around the outer wall of the flexible barrel 11 with the extrusion rod 121, it will also rotate relative to the extrusion rod 121 and roll on the outer wall of the flexible barrel 11. At this time, as the lifting device 124 (such as a cylinder) extends and retracts, the extrusion rod 121 and the kneading roller 122 will move up and down. As a result, the kneading roller 122 will roll on the outer wall of the flexible barrel 11 in a sinusoidal motion, kneading the flexible side wall 111.

[0085] The advantage of the above-described embodiment is that, during the process of the rubbing wheel 122 rolling on the outer wall of the flexible tub 11 in a sinusoidal motion, the rubbing wheel 122 can rub the flexible tub 11 repeatedly at multiple positions. Compared with the existing clothing processing equipment 1 that rubs the outer wall of the flexible tub 11 in a fixed position for a long time, the clothing processing equipment 1 of the present invention can improve the washing effect while the rolling and reciprocating multi-position rubbing also reduces the wear on the outer wall of the flexible tub 11, thus solving the problems of easy damage to the flexible tub 11 and unsatisfactory washing effect of the existing clothing processing equipment 1 with a flexible tub 11.

[0086] Regarding the lifting device 124, although the lifting device 124 mentioned above is a cylinder, this is not a limitation on the lifting device 124 of the present invention. If necessary, those skilled in the art can choose other common lifting devices 124, such as hydraulic cylinders, etc., which do not exceed the inventive principle of the present invention and are therefore all within the protection scope of the present invention.

[0087] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
