Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In the related art, a mounting passage for mounting a detergent box (ink cartridge) is generally provided at a panel of a washing machine, and laundry detergent may be stored in the detergent box. In addition, the washing equipment is also provided with a pump, a circuit component used for the normal operation of the pump body and the like, and the pump body can pump the detergent in the detergent box body to the waterway channel of the washing equipment to be mixed with the washing water when in operation. In this way, both the detergent box and the pump body occupy space of the laundry device, resulting in a larger overall volume of the laundry device.

Referring to fig. 1 and 2, fig. 1 is an external view schematically illustrating a laundry apparatus according to an embodiment of the present application, and fig. 2 is a partial structural sectional view of the laundry apparatus illustrated in fig. 1. The laundry device may include: the cartridge comprises an inner tube 100, an outer tube 200, a cartridge body 300 and a unidirectional flow member 400.

The drum 100 in the laundry device may be located within the tub 200, and the drum 100 may be rotatably connected with the tub 200. The inner barrel 100 may have a mounting hole 101 in communication with the outer barrel 200.

The cartridge 300 in the laundry device may be connected with the inner wall of the inner tub 100, and the cartridge 300 may have a first cavity 301 communicating with the mounting hole 101 on the inner tub 100, and the first cavity 301 may be used to contain a detergent.

The one-way circulation member 400 in the laundry device may be fixed in the mounting hole 101 on the inner tub 100, and an inlet of the one-way circulation member 400 may communicate with the first cavity 301 in the case 300, and an outlet of the one-way circulation member 400 may face the outer tub 200.

Wherein the unidirectional flow-through member 400 in the laundry device may be configured to: when the inner cylinder 100 rotates, the inner cylinder is conducted under the pressure exerted by the detergent in the first cavity 301, so that the detergent in the first cavity 301 flows out. By way of example, the one-way flow-through member 400 may be a one-way valve.

By way of example, by providing the cartridge 300 in the inner tub 100 of the laundry device, detergent can be directly stored in the first cavity 301 in the cartridge 300, and the one-way circulation member 400 communicating with the first cavity 301 is fixed in the mounting hole 101 in the inner tub 100. In this way, the detergent in the first chamber 301 can apply a force to the unidirectional flow member 400 by the centrifugal force during the rotation of the inner cylinder 100. The unidirectional flow member 400 can be opened under a certain acting force, so that the detergent in the first cavity 301 can flow into the area between the outer cylinder 200 and the inner cylinder 100 from the outlet of the unidirectional flow member 400, and then can be used for washing clothes after being mixed with the washing water injected into the washing equipment. In this way, it is only necessary to provide the cartridge 300 for storing the detergent and the one-way circulation member 400 for communicating with the cartridge 300 in the space of the inner tub 100, so that the detergent can be discharged from the inside of the cartridge 300. And the space occupied by the box 300 and the unidirectional flow component 400 is smaller and the cost is lower, so that the whole volume of the washing equipment integrated with the two components is smaller, and the miniaturization design of the washing equipment is facilitated. In addition, the washing water does not enter the first cavity 301, and does not pollute the rest of the washing agent in the first cavity 301.

In summary, embodiments of the present application provide a laundry device, which may include: an inner cylinder, an outer cylinder, a box body and a unidirectional flow component. By arranging the box body in the inner barrel of the washing equipment, the detergent can be directly stored in the first cavity in the box body, and the unidirectional circulating component communicated with the first cavity is fixed in the mounting hole in the inner barrel. Thus, during rotation of the inner barrel, the detergent in the first cavity can exert force on the unidirectional flow component under the action of centrifugal force. The unidirectional flow component can be opened under a certain acting force, so that the detergent in the first cavity can flow into the area between the outer cylinder and the inner cylinder from the outlet of the unidirectional flow component, and then can be used for cleaning clothes after being mixed with the washing water injected into the washing equipment. In this way, the detergent can be guided out of the box body only by arranging the box body for storing the detergent and the unidirectional circulating component for communicating with the box body in the space of the inner barrel. And the space occupied by the box body and the unidirectional flow component is smaller, and the cost is lower, so that the whole volume of the washing equipment integrated with the two components is smaller, and the miniaturized design of the washing equipment is facilitated.

Alternatively, referring to fig. 3, fig. 3 is a partial structural cross-sectional view of a laundry device according to an embodiment of the present application. A detergent bag A1 may be provided in the first cavity 301 in the case 300, and the detergent bag A1 may be used to contain a detergent. The outlet of the unidirectional flow-through member 400 may communicate with the outlet of the detergent bag A1. In this way, when the inner tube 100 rotates, the detergent bag A1 may be pressed by the centrifugal force to abut against the inner wall of the inner tube 100, thereby applying a pressing force to the detergent in the detergent bag A1. The detergent subjected to the pressing force flows into the region between the inner tub 100 and the outer tub 200 through the outlet of the detergent bag A1 and the inlet of the unidirectional flow-through member 400 and the outlet of the unidirectional flow-through member 400 in this order.

In embodiments of the present application, the laundry appliance may control the drum 100 to rotate at a first rotational speed relative to the tub 200 while the laundry appliance is in a detergent dispensing stage. The laundry appliance may control the drum 100 to rotate at the second rotational speed with respect to the tub 200 while the laundry appliance is in the washing stage. Wherein the first rotational speed may be greater than the second rotational speed. In this case, the user can control the drum 100 to rotate at the first rotation speed with respect to the tub 200 by the laundry device according to the opening force of the unidirectional flow-through part 400 used at the initial detergent dispensing stage (the opening force of the unidirectional flow-through part may be approximately equal to the centrifugal force provided when the drum rotates). And then, in the process of washing clothes, a user can adjust the rotating speed of the inner cylinder 100 relative to the outer cylinder 200 to be a second rotating speed through the washing device, so that the second rotating speed is smaller than the first rotating speed, and further, the centrifugal force of the inner cylinder 100 during rotation is smaller than the opening force of the unidirectional circulating component 400.

Alternatively, as shown in fig. 3, the inner tub 100 of the washing apparatus may have a lifting rib 102, where the lifting rib 102 and the case 300 may be integrally formed (i.e., the lifting rib of the inner tub of the washing apparatus may be used as the case, and a hollow structure formed by the lifting rib may be used as the first cavity). In this case, the lifting rib 102 in the drum 100 of the laundry device is used as the case 300. Therefore, the components in the washing equipment can be fully utilized to ensure that the washing equipment has the function of putting in the detergent, so that the cost of the washing equipment can be effectively reduced, and the integration degree of the washing equipment is improved. For example, a washing device (such as a drum washing machine) is configured to turn clothes up and down in a rotating manner to achieve washing, so that when the inner drum rotates, a lifting rib is required to be arranged in the inner drum, a certain acting force is applied to the clothes, and the clothes are driven to rotate along with the inner drum.

In the embodiment of the present application, please refer to fig. 4, fig. 4 is a partial structural cross-sectional view of another laundry apparatus provided in the embodiment of the present application. The lifting ribs 102 in the inner barrel 100 can include: a lifting rib body 1021, and a sliding cover plate 1022 located on a side of the lifting rib body 1021 facing away from the inner cylinder 100, the sliding cover plate 1022 being slidably connected to the lifting rib body 1021. In this case, by providing the lifting rib body 1021 and the sliding cover plate 1022 slidingly connected with the lifting rib body 1021 within the lifting rib 102. In this way, by sliding the sliding cover 1022 with respect to the lifting rib body 1021, detergent can be conveniently injected into the first cavity 301 of the lifting rib 102. For example, the number of the lifting ribs 102 in the inner cylinder 100 may be plural, and the plurality of lifting ribs 102 may be provided as a lifting rib body 1021 and a sliding cover plate 1022 slidably connected to the lifting rib body 1021. In this way, when the inner tub 100 stops rotating, detergent can be supplied to the lifting rib 102 located at the lowermost side (i.e., the lifting rib having the smallest distance from the ground), and the lifting rib 102 is also convenient for the user to operate.

Optionally, as shown in fig. 4, the laundry device may further include: a barrier 500 fixed on the outer wall of the inner cylinder 100, the barrier 500 may have a second cavity 501 and a through hole 502 communicating with the second cavity 501, and the barrier 500 may be located between the inner cylinder 100 and the outer cylinder 200. The outlet of the unidirectional flow-through member 400 in the laundry appliance may be in communication with the second cavity 501 in the barrier 500. Wherein the barrier 500 may be configured to: the washing water in the washing apparatus is soaked and then expanded to be abutted with the outlet of the one-way circulation member 400. In this case, the inner tub 100 in the laundry apparatus is rotated so that the detergent in the first chamber 301 can flow into the second chamber 501 through the outlet of the unidirectional flow-through member 400, and the washing water introduced into the laundry apparatus can be introduced into the second chamber 501 through the through-hole 502 of the barrier 500 to be mixed with the detergent. The mixed washing liquid can flow again from the through holes 502 of the barrier 500 to the region between the inner tub 100 and the outer tub 200 to wash the laundry. In addition, the blocking member 500 is also soaked in the washing water flowing into the washing apparatus and then expands, and after the expansion is performed to a certain extent, the blocking member 500 can block the outlet of the unidirectional flow-through part 400, so that the washing agent in the first cavity 301 can not flow to the second cavity 501 any more during the subsequent washing and dehydrating processes of the washing apparatus. It should be noted that, after the washing device completes the washing and the subsequent dewatering, the blocking member 500 can automatically recover to the initial state after a period of time, so as to facilitate the next normal use of the washing device. By way of example, at least a portion of the one-way flow-through member 400 secured within the mounting hole 101 on the inner barrel 100 may be located within the second cavity 501 in the barrier 500. In this way, the blocking member 500 is more conveniently abutted with the outlet of the one-way circulation member 400 after being soaked and expanded by the washing water entering the washing apparatus.

In an embodiment of the present application, please refer to fig. 4 and 5, fig. 5 is a partial structural cross-sectional view of still another laundry apparatus provided in an embodiment of the present application. The barrier 500 in the laundry device may include: annular side plate 503 and bottom plate 504, the one end of annular side plate 503 can be with inner tube 100 fixed connection, and the other end of annular side plate 503 can with bottom plate 504 fixed connection. The through holes 502 in the barrier 500 may be located on the annular side plate 503 and the bottom plate 504 may be located on the side of the outlet of the unidirectional flow-through member 400 facing away from the inner barrel 100. Wherein the amount of expansion of the bottom plate 504 after the barrier 500 is soaked with the laundry water entering the laundry device is greater than the distance between the bottom plate 504 and the outlet of the unidirectional flow-through member 400 (i.e., the amount of expansion of the bottom plate after the barrier is soaked with the laundry water is greater than the distance between the bottom plate and the outlet of the unidirectional flow-through member before the bottom plate is not expanded). In this case, by providing the distance between the bottom plate 504 of the barrier 500 and the unidirectional flow-through member 400 to be smaller than the expansion amount of the bottom plate 504 after the barrier 500 is soaked in the laundry water, the blocking effect of the bottom plate 504 on the outlet of the unidirectional flow-through member 400 after being expanded to a certain degree can be effectively ensured.

Alternatively, as shown in fig. 5, at least part of the unidirectional flow component 400 in the laundry appliance may be located within the second cavity 501 in the barrier 500. The width of the annular side plate 503 of the blocking member 500 toward the inner cylinder 100 may be greater than the width of the annular side plate 503 toward the outer cylinder 200. In this case, the width of the annular side plate 503 of the stopper 500 toward the inner cylinder 100 is larger than the width of the annular side plate 503 toward the outer cylinder 200. In this way, the volume of the partial area in the second cavity 501 surrounded by the annular side plate 503 and the bottom plate 504 can be ensured to be larger, so that more detergent can be conveniently contained; while the smaller width of annular side plate 503 ensures that bottom plate 504 more readily abuts the outlet of unidirectional flow-through member 400 after expansion. It should be noted that, in other possible implementations, the width of the annular side plate 503 on the side facing the inner cylinder 100 in the blocking member 500 may be equal to the width of the annular side plate 503 on the side facing the outer cylinder 200, which is not specifically limited in the embodiment of the present application.

In the embodiment of the present application, as shown in fig. 5, a surface of the annular side plate 503 of the barrier 500 facing away from the unidirectional flow-through member 400 may be a concave surface a1. In this case, the annular side plate 503 has a concave surface a1 on the side facing away from the unidirectional flow path member 400. In this way, the impact between the washing water and the barrier 500 in the process of entering the second cavity 501 can be reduced, and the efficiency of the washing water entering the second cavity 501 is improved. It should be noted that, in other possible implementations, the side of the annular side plate 503 of the barrier 500 facing away from the unidirectional flow component 400 may also be a plane, which is not specifically limited in the embodiment of the present application.

Alternatively, as shown in fig. 5, the number of through holes 502 in the blocking member 500 may be plural, and at least two through holes 502 in the plural through holes are disposed opposite to each other. In this case, by providing a plurality of through holes 502 in the barrier 500, at least two through holes 502 among the plurality of through holes 502 are provided opposite to each other. In this way, the washing water can be mixed with the detergent after entering from one of the two through holes 502 which are oppositely arranged, and then can quickly flow out from the other of the two through holes, so that the mixing efficiency of the washing water and the detergent is effectively provided.

In the embodiment of the present application, the barrier 500 in the laundry device may be a structure made of expanded rubber. In the application, the barrier is manufactured by using the expansion rubber, which is a material capable of expanding when encountering water, and has higher expansion rate and better elasticity and adhesiveness. It should be noted that, the blocking member 500 may be a structure made of other materials, and may be capable of ensuring that the blocking member expands to block the outlet of the unidirectional flow component after water accumulation is encountered, which is not particularly limited in the embodiment of the present application.

In summary, embodiments of the present application provide a laundry device, which may include: an inner cylinder, an outer cylinder, a box body and a unidirectional flow component. By arranging the box body in the inner barrel of the washing equipment, the detergent can be directly stored in the first cavity in the box body, and the unidirectional circulating component communicated with the first cavity is fixed in the mounting hole in the inner barrel. Thus, during rotation of the inner barrel, the detergent in the first cavity can exert force on the unidirectional flow component under the action of centrifugal force. The unidirectional flow component can be opened under a certain acting force, so that the detergent in the first cavity can flow into the area between the outer cylinder and the inner cylinder from the outlet of the unidirectional flow component, and then can be used for cleaning clothes after being mixed with the washing water injected into the washing equipment. In this way, the detergent can be guided out of the box body only by arranging the box body for storing the detergent and the unidirectional circulating component for communicating with the box body in the space of the inner barrel. And the space occupied by the box body and the unidirectional flow component is smaller, so that the whole volume of the washing equipment integrated with the two components is smaller, and the miniaturized design of the washing equipment is facilitated.
