Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, and specifically relates to an improvement in the structure of a clothing washing device. Background Technology

[0002] Existing pulsator washing machines are equipped with pulsators to improve the washing effect of clothes. These pulsators have raised ribs. During washing, the rotation of the pulsator drives the raised ribs to rotate, thus achieving a rubbing and washing effect on the clothes. However, because the raised ribs come into direct contact with and rub against the clothes when the pulsator rotates and rubs, especially when the motor is rotating at high speed, the friction between the raised ribs and the clothes is intensified. This not only causes wear and damage to the washed clothes, but also results in poor washing performance. Summary of the Invention

[0003] This invention addresses the problems of existing pulsator washing machines, which easily cause wear and tear on clothes and have poor washing effects. This invention proposes a novel clothes washing device that uses a first spray section on the inner drum and a second spray section on the drain component to spray and wash clothes during washing, effectively avoiding the problem of wear and tear on clothes during washing. Furthermore, the first and second spray sections rotate circumferentially during washing, resulting in better spray and washing effects on clothes.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0005] A laundry washing device includes:

[0006] An outer cylinder, on which a fixing part is formed;

[0007] An inner cylinder is located inside the outer cylinder and forms a water-containing space between them. A first spray section is formed on the inner cylinder and communicates with the internal space of the inner cylinder.

[0008] A rotating part is rotatably connected to the fixed part, and a rotary flow channel is formed between the rotating part and the fixed part, which is arranged around the inner cylinder in the circumferential direction. The rotary flow channel is connected to the first spray part.

[0009] A connecting channel connects the rotary flow channel and the water-containing space;

[0010] A drainage component is provided on the inner cylinder, and a drainage channel and a second spray section communicating with the drainage channel are formed on the drainage component. The drainage channel is connected to the rotary flow channel.

[0011] The power element, connected to the connecting channel, is used to transport water from the water-containing space to the rotating flow channel.

[0012] In some embodiments of this application, the laundry washing apparatus further includes:

[0013] A flow guide channel is formed on the inner cylinder, connecting the rotary flow channel, the first spray section and the drainage channel, to guide the water flow in the rotary flow channel to the first spray section and the drainage channel respectively.

[0014] In some embodiments of this application, the fixing part is a first rotating component fixed on the outer cylinder or a fixing protrusion formed on the outer cylinder, and the rotating part is a second rotating component fixedly connected to the inner cylinder or a rotating protrusion formed on the inner cylinder.

[0015] In some embodiments of this application, grooves are formed on the fixed part and / or the rotating part, and the fixed part and the rotating part are mated together to form the rotary flow channel.

[0016] In some embodiments of this application, a rotary connection structure that cooperates with each other is provided between the fixed part and the rotating part.

[0017] The rotary connection structure includes an annular protrusion / annular groove disposed on the first rotary component and an annular groove / annular protrusion disposed on the second rotary component.

[0018] In some embodiments of this application, a water flow communication section for connecting the two is provided between the rotary flow channel and the guide flow channel. Multiple water flow communication sections are provided and arranged along the circumference of the inner cylinder.

[0019] In some embodiments of this application, multiple rotary flow channels are formed and arranged sequentially from top to bottom along the height direction of the inner cylinder. Multiple guide channels are provided and are respectively connected to multiple rotary flow channels. Multiple first spray sections are provided and are arranged along the height direction of the inner cylinder and are respectively connected to multiple guide channels. Multiple drainage channels are provided and are respectively connected to multiple guide channels.

[0020] In some embodiments of this application, one rotary flow channel is formed, multiple flow guide channels are provided, and multiple flow guide channels are all connected to the rotary flow channel. Multiple first spray sections are provided and are respectively connected to the multiple flow guide channels. Multiple drainage channels are provided and are connected to the multiple flow guide channels.

[0021] In some embodiments of this application, a support portion is formed at the bottom region of the inner cylinder and arranged circumferentially thereon. The first spray portion is disposed on the support portion, the drainage component is disposed above the support portion, and the second spray portion is arranged in multiple rows, with multiple spray portions in each row, and the multiple spray portions in each row are arranged from top to bottom along the height direction of the drainage component.

[0022] In some embodiments of this application, the flow guiding channel is formed on the support portion and includes a flow storage channel arranged circumferentially along the inner cylinder and a water guiding channel arranged axially along the drainage component. The flow storage channel and the water guiding channel are connected to the first spraying part, and the first spraying part and the water guiding channel are staggered on the support portion.

[0023] In some embodiments of this application, a controller is also included. Multiple connecting components are provided, which are respectively connected to the water-containing space and the multiple rotating channels. Each connecting component is provided with a control element for controlling the opening and closing of the rotating channels and the water-containing space. The control element is communicatively connected to the controller.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are:

[0025] The laundry washing device of the present invention has a fixed part on the outer drum and a rotating part on the inner drum, which is rotatably connected to the fixed part and forms a rotary flow channel between them. At the same time, the inner drum has a drain component and a first spray component, and the first spray component and the second spray component on the drain component are both connected to the rotary flow channel. When washing clothes, the water flow is guided into the rotary flow channel by a power element and the water flow is sprayed out from the first spray component and the second spray component to wash the clothes, instead of washing the clothes by friction between the impeller at the bottom of the inner drum. This effectively avoids the problem of wear and tear on the clothes during washing and achieves protection during the washing process.

[0026] Furthermore, since both the drainage component and the first spray section are located on the inner drum, and the rotating part is rotatably connected to the fixed part, during washing, as the inner drum rotates circumferentially, it will drive the second spray section on the drainage component above it and the first spray section on the inner drum to rotate circumferentially as well. When washing clothes, the first spray section and the second spray section continuously rotate circumferentially to spray and wash the clothes inside the inner drum, achieving 360-degree spraying of the clothes inside the inner drum without dead angles, resulting in better washing effect.

[0027] Other features and advantages of the present invention will become clearer after reading the detailed embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] This invention provides an embodiment of a clothing washing device, comprising:

[0048] outer cylinder 100;

[0049] The inner cylinder 300 is located inside the outer cylinder 100, and a water-containing space 800 is formed between the inner cylinder 300 and the outer cylinder 100.

[0050] During washing, external water flows into the water-containing space 800 between the outer drum 100 and the inner drum 300 through the water inlet provided on the outer drum 100.

[0051] In order to allow the water in the water-containing space 800 to enter the inner drum 300 for washing, multiple water inlets are provided on the inner drum 300. The water inlets are arranged in multiple rows, with multiple inlets in each row, and the water inlets in each row are evenly spaced along the height of the inner drum 300.

[0052] Existing pulsator washing machines are equipped with pulsators to improve the washing effect of clothes. The pulsator has raised ribs, which rotate when the pulsator rotates, thus achieving the effect of rubbing and washing clothes. However, because the pulsator comes into direct contact with the clothes when it rotates, especially at high speeds, it can cause some wear and damage to the clothes being washed.

[0053] To address the problem that existing pulsator washing machines easily cause wear and damage to clothes during washing, the clothes washing device proposed in this embodiment directly eliminates the pulsator structure. The pulsator structure is omitted from the bottom wall of the inner drum 300, and the washing method adopts a spray type.

[0054] In a specific configuration, a fixing part 200 is formed on the outer cylinder 100;

[0055] A first spray section 310 is formed on the inner cylinder 300, which communicates with the internal space of the inner cylinder 300;

[0056] A rotating part 400 is rotatably connected to the fixed part 200. A rotary flow channel 500 is formed between the rotating part 400 and the fixed part 200, which is arranged around the inner cylinder 300 in a circumferential direction. The rotary flow channel 500 is connected to the first spray part 310.

[0057] A connecting channel connects the rotary flow channel 500 and the water-containing space 800;

[0058] In some embodiments of this application, the connecting channel is a connecting pipe, one end of which is inserted into the water-containing space 800 and the other end of which is inserted into the rotary flow channel 500 to connect the rotary flow channel 500 and the water-containing space 800.

[0059] During setup, insertion holes can be made on the rotary flow channel 500, and corresponding sealing elements can be installed around the insertion holes to achieve a sealed connection.

[0060] A drainage component 600 is disposed on the inner cylinder 300. A drainage channel 620 and a second spray section 610 communicating with the drainage channel 620 are formed on the drainage component 600. The drainage channel 620 is communicating with the rotary flow channel 500.

[0061] A power element, connected to the connecting channel, is used to transport water from the water-containing space 800 to the rotary flow channel 500.

[0062] In some embodiments, the power element is a water pump, which can be used to pump water from the water-containing space 800 into the rotary channel 500.

[0063] During assembly, the power components can be mounted on the outer wall of the outer cylinder 100 to prevent water from entering its interior.

[0064] When the washing machine is working, external water will enter the water-holding space 800 between the inner drum 300 and the outer drum 100 through the water inlet pipe or the water inlet on the outer drum 100. After water enters the water-holding space 800, the power element can be turned on and the motor can be turned on.

[0065] Since the inner cylinder 300 is connected to the motor, the operation of the motor will drive the inner cylinder 300 connected to it to rotate. Since the rotating part 400 is formed on the inner cylinder 300, when the inner cylinder 300 rotates, it will drive the rotating part 400 to rotate. Since the rotating part 400 is rotatably connected to the fixed part 200, the rotating part 400 can rotate continuously relative to the fixed part 200.

[0066] At the same time, after the power element is turned on, it begins to work, and through the connecting component, it transports the water in the water-containing space 800 to the rotary flow channel 500.

[0067] Since the drainage channel 620 of the drainage component 600 and the first spray section 310 on the inner drum 300 are both connected to the rotary flow channel 500, under the power drive of the power element, water can be sprayed from the first spray section 310 connected to the rotary flow channel 500 and the second spray section 610 on the drainage channel 620 into the inner drum 300, so as to achieve the effect of spraying and washing clothes inside the inner drum 300.

[0068] Since the washing device in this embodiment mainly washes clothes by the water sprayed from the first spray section 310 and the second spray section 610, rather than by the impeller at the bottom of the inner drum 300 rubbing against the clothes, it can effectively avoid the problem of wear and tear on the clothes during washing, thus achieving protection during the washing of clothes.

[0069] Furthermore, since the drain component 600 and the first spray section 310 are both mounted on the inner drum 300, and the rotating section 400 is rotatably connected to the fixed section 200, during washing, as the inner drum 300 rotates circumferentially, it will drive the second spray section 610 on the drain component 600 above it and the first spray section 310 on the inner drum 300 to also rotate circumferentially. When washing clothes, the first spray section 310 and the second spray section 610 continuously rotate circumferentially to spray and wash the clothes inside the inner drum 300. During rotation, they can spray different parts of the clothes, so as to achieve 360-degree spraying of the clothes inside the inner drum 300 without dead angles, resulting in better washing effect.

[0070] Furthermore, since the water jets sprayed from the first spray section 310 and the second spray section 610 are pressurized by the power element, the water jets sprayed from the first spray section 310 and the second spray section 610 can be guaranteed to have a certain water pressure, which can ensure that the appropriate spray force is applied to the clothes inside the inner drum 300, and will not cause impact damage to the clothes inside the inner drum 300, thereby further improving the cleaning power of the clothes.

[0071] In some embodiments of this application, the laundry washing apparatus further includes:

[0072] A flow channel 700 is formed on the inner cylinder 300, connecting the rotary flow channel 500, the first spray section 310 and the drainage channel 620, to guide the water flow in the rotary flow channel 500 to the first spray section 310 and the drainage channel 620 respectively.

[0073] The water in the rotary flow channel 500 will flow out of the rotary flow channel 500 and flow into the guide channel 700 on the inner cylinder 300. Then, through the guide channel 700, it will be sprayed into the inner cylinder 300 from the first spray section 310 and the second spray section 610 in the drainage channel 620 respectively.

[0074] The flow guide channel 700 is used to guide the water flow out of the rotary flow channel 500.

[0075] The fixing part 200 is a first rotating component fixed on the outer cylinder 100 or a fixing protrusion formed on the outer cylinder 100, and the rotating part 400 is a second rotating component fixedly connected to the inner cylinder 300 or a rotating protrusion formed on the inner cylinder 300.

[0076] In some embodiments of this application, the fixing part 200 is a fixing protrusion that is integrally formed with the outer cylinder 100. The fixing protrusion can be integrally injection molded with the outer cylinder 100 through a mold. The fixing protrusion is annular and arranged circumferentially along the inner wall of the outer cylinder 100. It is located inside the water-containing space 800 between the outer cylinder 100 and the inner cylinder 300.

[0077] The rotating part 400 is a rotating protrusion that is integrally formed with the inner cylinder 300. It is also annular, with its outer side flush with the outer side of the inner cylinder 300. The outer side can also protrude from the outer side of the inner cylinder 300. Its height is adapted to the fixing part 200 and is used to cooperate with the fixing part 200.

[0078] In some other embodiments of this application, a second rotating component may be fixedly connected to the outer cylinder 100 for the molding fixing part 200, and correspondingly, a first rotating component may be fixedly connected to the inner cylinder 300 for the molding rotating part 400.

[0079] The second rotating component and the outer cylinder 100 can be connected by a connecting rod. The two ends of the connecting rod can be provided with external threads, and the inner wall of the outer cylinder 100 and the second rotating component can be provided with internal threads. The two ends of the connecting rod are tightened and fixed in the outer cylinder 100 and the second rotating component respectively to connect and fix the two.

[0080] The first rotating component can be fixedly connected to the inner cylinder 300 by locking screws, or it can be fixed to the inner cylinder 300 by adhesive.

[0081] During installation, a notch can be made on the side wall of the inner cylinder 300, and the component can be installed at the notch position to seal the notch. Preferably, the outer side of the first rotating component and the outer side of the inner cylinder 300 are kept flush.

[0082] In some embodiments of this application, grooves are formed on the fixed part 200 and / or the rotating part 400, and the fixed part 200 and the rotating part 400 are mated together to form the rotary flow channel 500.

[0083] When setting it up, a groove can be provided on the surfaces of the fixed part 200 and the rotating part 400 that are opposite each other, so that a rotary flow channel 500 can be formed between the two.

[0084] Alternatively, grooves can be formed on the surfaces of the rotating part 400 and the fixed part 200 that are opposite to each other, or grooves can be formed on both the fixed part 200 and the rotating part 400 at the same time, so that the two can form a hollow rotating flow channel 500 after docking and fitting together, for the flow of water. No specific restrictions are made here.

[0085] In some embodiments of this application, a rotary connection structure is provided between the fixed part 200 and the rotating part 400. The rotary connection interface between the two allows the rotating part 400 to rotate relative to the fixed part 200.

[0086] In some embodiments of this application, the rotary connection structure includes an annular locking protrusion 210 / annular locking groove 410 disposed on the fixed part 200 and an annular locking groove 410 / annular locking protrusion 210 disposed on the rotating part 400.

[0087] During installation, an annular protrusion 210 can be provided on the fixed part 200, and an annular groove 410 can be provided on the rotating part 400;

[0088] Alternatively, an annular groove 410 can be provided on the fixed part 200, and an annular protrusion 210 can be provided on the rotating part 400. During mating, the annular protrusion 210 is inserted into the annular groove 410 to achieve relative rotation between the fixed part 200 and the rotating part 400.

[0089] In some embodiments of this application, a water flow communication portion 420 for connecting the two is provided between the rotary flow channel 500 and the guide flow channel. Multiple water flow communication portions 420 are provided and arranged circumferentially along the inner cylinder 300.

[0090] The water flow connecting part 420 is a water flow connecting hole, which is provided on the rotating part 400 and extends through the rotating part 400 so that the water flow in the rotating flow channel 500 can be introduced into the guide flow channel.

[0091] Multiple water flow connecting holes can be set up and arranged around the inner cylinder 300 to allow a large amount of water in the rotating flow channel 500 to be introduced into the guide flow channel, ensuring the water flow rate from the guide flow channel, and thus ensuring the amount of spray water sprayed into the interior from the guide flow channel, thereby ensuring the spraying effect.

[0092] In some embodiments of this application, multiple rotary flow channels 500 are formed and arranged sequentially from top to bottom along the height direction of the inner cylinder 300. Multiple guide channels 700 are provided and are respectively connected to multiple rotary flow channels. Multiple first spray sections 310 are provided and are arranged along the height direction of the inner cylinder 300 and are respectively connected to multiple guide channels 700. Multiple drainage channels 620 are provided and are respectively connected to multiple guide channels 700.

[0093] In a specific arrangement, multiple annular protrusions 210 are provided on the fixed part 200, and multiple annular grooves 410 are provided on the rotating part 400.

[0094] When the annular protrusions 210 are set, they are equally spaced from top to bottom along the height direction of the fixed part 200. Multiple annular slots 410 are arranged from top to bottom along the height of the rotating part 400. When they are engaged, the multiple annular slots 410 are respectively engaged into the multiple annular protrusions 210 to form multiple rotary flow channels 500 between them.

[0095] By using multiple annular protrusions 210 and multiple annular grooves 410, multiple mutually separated rotary flow channels 500 can be formed, and the sealing performance of each rotary flow channel 500 can be guaranteed.

[0096] The flow channel 700 is also provided on the inner cylinder 300 in multiple ways and is spaced apart from each other, so as to connect multiple drainage channels 620 and multiple first spray sections 310 respectively.

[0097] During spraying, the water flowing out from the multiple rotating channels 500 flows into the corresponding guide channels 700, and then is sprayed outward from the first spray section 310 and the second spray section 610 on the drainage channel 620, which are connected to the corresponding guide channels 700.

[0098] In some embodiments, the second spray section 610 is a second spray hole, and the drainage component 600 is a drainage plate with a hollow drainage channel 620 formed inside it. The drainage channel 620 is arranged in multiple rows and is connected to multiple guide channels 700 respectively. Each row is provided with the second spray hole. The second spray holes are arranged from top to bottom along the height direction of the inner cylinder 300 so that the water flowing into each row of drainage channels 620 can be sprayed out into the inner cylinder 300 from the second spray holes at different positions to achieve different degrees of spray rinsing effect on the clothes.

[0099] In other embodiments, a hollow drainage channel 620 is formed inside the drainage component 600, which is connected to multiple flow channels 700. Multiple rows of second spray holes are provided on the drainage channel 620, which can also achieve the spraying effect.

[0100] During setup, multiple annular protrusions 210 and multiple annular grooves 410 can be simultaneously provided on the fixing part 200, with the annular protrusions 210 and annular grooves 410 arranged alternately. Similarly, multiple alternating annular protrusions 210 and multiple annular grooves 410 are also arranged on the rotating part 400. During insertion and assembly, the annular protrusions 210 on the fixing part 200 and the annular grooves 410 on the rotating part 400 are inserted and assembled, and the annular grooves 410 on the fixing part 200 and the annular protrusions 210 on the rotating part 400 are mated and assembled to form multiple rotary flow channels 500.

[0101] In some embodiments of this application, one rotary flow channel 500 is formed, multiple flow guide channels 700 are provided, and multiple flow guide channels 700 are all connected to the rotary flow channel 500. Multiple first spray sections 310 are provided and are respectively connected to the multiple flow guide channels 700. Multiple drainage channels 620 are provided and are connected to the multiple flow guide channels 700.

[0102] In other words, during setup, one rotary flow channel 500, multiple guide channels 700, and multiple drainage channels 620 can be set to achieve a multi-channel, multi-position spraying effect.

[0103] In some embodiments of this application, a support portion 320 is formed at the bottom region of the inner cylinder 300 and arranged circumferentially thereon. The first spray portion 310 is disposed on the support portion 320, the drainage component 600 is disposed above the support portion 320, and the second spray portion 610 is arranged in multiple rows, with multiple spray portions in each row, and the multiple spray portions in each row are arranged from top to bottom along the height direction of the drainage component 600.

[0104] The support part 320 is located at the bottom area of ​​the inner cylinder 300. During molding, it can be integrally formed with the inner cylinder 300 through a mold. The support part 320 is a support platform that extends from the inner wall of the inner cylinder 300 into the internal space of the inner cylinder 300.

[0105] The support platform is arranged circumferentially along the inner cylinder 300, and it is an annular support platform. The drainage component 600 is arranged on the top surface of the support platform.

[0106] To achieve proper fit with the support platform, the bottom of the drainage component 600 has a connecting part, which is a connecting flange. When it is connected to the support platform of the inner cylinder 300, the drainage component 600 can be screwed and fixed to the support platform by providing threaded holes on the connecting part.

[0107] The first spray section 310 is disposed on the side wall of the support section 320 at the bottom area of ​​the inner drum 300 and arranged along the height direction of the support section 320, so as to ensure that the clothes at the bottom area of ​​the inner drum 300 can be sprayed through the first spray section 310.

[0108] A drainage component 600 with a second spray section 610 is arranged above the support section 320, and multiple components are arranged along the height direction of the inner drum 300. This ensures that the clothes in the inner drum 300 located in the area above the support section 320 can be sprayed through the second spray section 610. The cooperation between the first spray section 310 located at the bottom of the inner drum 300 and the second spray section 610 located in the area above the inner drum 300 ensures that there are corresponding spray holes from the bottom to the top of the inner drum 300 to spray the clothes inside the inner drum 300, thus ensuring the comprehensiveness of the spraying and the effectiveness of the spray washing of the clothes placed in the inner drum 300.

[0109] In some embodiments of this application, the flow channel 700 is formed on the support portion 320 and includes a flow storage channel 710 arranged circumferentially along the inner cylinder 300 and a water guide channel 720 arranged along the axial direction of the drainage component 600. The flow storage channel 710 is connected to the water guide channel and the first spray portion 310. The first spray portion 310 and the water guide channel 720 are staggered on the support portion 320.

[0110] The water storage channel is an annular water storage channel formed between the support platform and the rotating part 400. The first spray part 310 and the water guide channel 720 are both connected to the annular water storage channel. The water guide channel 720 is connected at the top of the water storage channel, and the first spray part 310 is connected at the side wall of the water storage channel.

[0111] Furthermore, the center line of the first spray section 310 and the center line of the water guide channel 720 are staggered and do not intersect, so as to ensure that the water flow can be sprayed outward from the first spray section 310 and the second spray section 610 respectively.

[0112] If the center line of the first spray section 310 and the center line of the water guide channel 720 intersect, the water in the water storage channel will flow from the same position to the first spray section 310 and the water guide channel 720. The insufficient spray water flow will result in a small water flow rate in the first spray section 310 or the second spray section 610, affecting the spraying effect.

[0113] In some embodiments of this application, a controller is also included. Multiple connecting components are provided, which are respectively connected to the water-containing space 800 and the multiple rotating channels 500. Each connecting component is provided with a control element for controlling the opening and closing of the rotating channels 500 and the water-containing space 800. The control element is communicatively connected to the controller.

[0114] To enable individual control of each drainage channel 620, multiple connecting components are connected to multiple rotary channels 500. A controller is used to control the control elements to alternately control the water inlet flow in the multiple rotary channels 500, thereby achieving control of the multiple drainage channels 620 connected to the multiple rotary channels 500.

[0115] The control element can be a solenoid valve, which is controlled by a controller to open and close.

[0116] In some embodiments, the multiple connecting components are configured as multiple diversion pipes, and electromagnetic reversing valves are connected to the multiple diversion pipes. The electromagnetic reversing valves are communicatively connected to the controller, and the controller controls the operation of the electromagnetic reversing valves so that they can switch between the multiple diversion pipes, thereby allowing the water flow in the water-containing space 800 to flow rotatably into any of the rotary flow channels 500.

[0117] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
