Description

Technical Field

[0001] The invention belongs to the technical field of accessories for washing machines, and in particular relates to a washing ball. Background Art

[0002] At present, there are still many drum washing machines on the market that do not have an automatic system for dispensing laundry products, or do not have a system for dispensing detergents including laundry detergent and softener. Therefore, due to the structural limitations of the drum washing machine, users usually need to bend over to pour the detergent into the washing tub, which is extremely inconvenient, especially for the elderly. Sometimes, the detergent will spill and stain the floor.

[0003] In view of the above problems, a washing ball is invented in the prior art to solve the problem. The washing ball includes an integrally formed shell structure, a hollow receiving chamber is provided in the shell, and a detergent delivery opening is provided on the shell. When in use, the user pours the detergent into the receiving chamber through the detergent delivery opening on the washing ball, and then throws the washing ball into the drum. During the washing process, the washing ball will turn over as the washing drum rotates, so that the detergent in the receiving chamber enters the washing drum through the detergent delivery opening to assist the washing machine in washing clothes.

[0004] However, in the laundry ball provided by the above solution, the detergent in the laundry ball is not easy to completely enter the washing drum from the receiving chamber, that is, detergent residue is easy to remain in the receiving chamber. Since the detergent does not completely enter the washing drum, the clothes may not be washed cleanly. Moreover, the residual detergent may enter the washing drum during the rinsing process, and finally the clothes are not rinsed cleanly.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing ball, in which the detergent in the containing cavity can be completely put into the washing drum during the washing process.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] Provided is a laundry ball, the laundry ball having a containing cavity and an addition discharge port communicated with the containing cavity;

[0009] Under the action of external force, the accommodating cavity of the laundry ball is deformed and opened, releasing the clothing treatment agent therein.

[0010] The laundry ball provided by the present invention is impacted as the washing drum rotates during the washing process. Under the force, the accommodating cavity is deformed and opened to release the laundry treatment agent. Since the accommodating cavity is in an open state, the laundry treatment agent flows more easily from the accommodating cavity into the washing drum. In addition, the washing water also flushes the accommodating cavity, so that the detergent in the accommodating cavity completely enters the washing drum. This solution can avoid the residue of the laundry treatment agent in the accommodating cavity, thereby ensuring the washing effect.

[0011] Furthermore, the laundry ball comprises a first shell and a second shell, and the first shell and the second shell are connected to each other to form a receiving cavity;

[0012] During the washing process, the first housing and the second housing are at least partially separated under the action of an external force to release the laundry treatment agent;

[0013] Wherein, the addition discharge port is arranged on the first shell and / or the second shell.

[0014] Furthermore, the first shell and the second shell are both open; the addition discharge port is arranged on the first shell and is arranged opposite to the opening of the first shell;

[0015] The first shell is provided with a groove at the open position thereof;

[0016] The second shell is provided with a protruding structure at the open position thereof;

[0017] The protruding structure on the second shell is inserted into the groove on the first shell for connection.

[0018] Furthermore, the groove is formed by the outer surface of the first shell being sunken toward the central axis of the washing ball;

[0019] The protruding structure is formed by the second shell protruding toward the central axis direction of the washing ball.

[0020] Further, the hardness of the first shell is different from the hardness of the second shell;

[0021] The first shell and / or the second shell is deformed by external force, the protrusion structure escapes from the groove, and the first shell and the second shell are separated to release the clothing treatment agent.

[0022] Furthermore, the first shell body also has an opening, and the opening is arranged opposite to the open end of the first shell body;

[0023] A side wall is formed by extending obliquely from the opening of the first shell toward the inside of the washing ball and gradually approaching the central axis of the washing ball, and the extended end of the side wall surrounds the addition and discharge port.

[0024] Furthermore, at least one flow guide wall is formed by extending from the addition and discharge port on the first shell toward the bottom of the second shell.

[0025] Furthermore, the guide wall has scale lines.

[0026] Furthermore, a liquid through hole is provided on the side wall.

[0027] Furthermore, the liquid through hole is arranged at an end of the side wall away from the addition and discharge port.

[0028] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0029] 1. The laundry ball provided by the present invention will be impacted as the washing drum rotates during the washing process. Under the force, the accommodating cavity will deform and open, releasing the laundry treatment agent. Since the accommodating cavity is in an open state, the laundry treatment agent can more easily flow from the accommodating cavity into the washing drum. In addition, the washing water will also flush the accommodating cavity, so that the detergent in the accommodating cavity can completely enter the washing drum. This solution can avoid the residue of laundry treatment agent in the accommodating cavity, ensuring the washing effect.

[0030] 2. The laundry ball provided by the present invention has a side wall on the first shell, and the extended end of the side wall forms a feed outlet. Compared with a laundry ball with a direct opening, the side wall can prevent the detergent in the accommodating cavity from spilling out of the feed outlet when the laundry ball is placed in the washing drum.

[0031] 3. The technical solution provided by the present invention prevents the splashing of the clothing treatment agent when the clothing treatment agent is added because the guide wall is provided.

[0032] 4. In the solution provided by the present invention, since scale lines are arranged on the guide wall, the dosage of the laundry treatment agent to be added can be accurately controlled.

[0033] 5. In the solution provided by the present invention, since the liquid through hole is arranged on the side wall, even if the accommodating cavity is not opened, the clothing treatment agent in the washing ball can be discharged from the accommodating cavity through the addition discharge port and the liquid through hole.

[0034] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figures 1 to 4As shown, the present invention provides a laundry ball 100.

[0048] The laundry ball 100 has a containing cavity and a adding and discharging port 3 connected to the containing cavity;

[0049] Under the action of external force, the accommodating cavity of the laundry ball 100 is deformed and opened, releasing the laundry treatment agent therein.

[0050] In the laundry ball provided by the present invention, the detergent in the accommodating cavity can completely enter the washing drum, and no clothes treating agent remains in the laundry ball.

[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a laundry ball 100.

[0053] The laundry ball 100 has a containing cavity and a adding and discharging port 3 connected to the containing cavity;

[0054] Under the action of external force, the accommodating cavity of the laundry ball 100 is deformed and opened, releasing the laundry treatment agent therein.

[0055] The laundry ball 100 provided in this embodiment has a accommodating cavity and an addition and discharge port 3 connected to the accommodating cavity. When in use, the user pours the laundry treatment agent into the accommodating cavity through the addition and discharge port 3, and then throws the laundry ball 100 into the washing drum. During the operation of the washing program, the laundry ball 100 will roll with the laundry in the washing drum. When the washing drum stops rotating, the force acting on the laundry ball 100 disappears, and the laundry ball 100 will fall into the washing drum and collide with the inner wall of the washing drum. The accommodating cavity of the laundry ball 100 is deformed and opened under the external force, releasing the laundry treatment agent. Specifically, under the external force, the wall of the accommodating cavity is deformed inwardly, so that the accommodating cavity opens and releases the laundry treatment agent.

[0056] It is worth noting that the washing machine described in this embodiment is a drum washing machine. The clothes are lifted up by the lifting ribs of the washing drum and then fall and hit. At the same time, the washing ball 100 will be lifted up along with the clothes and then fall and hit under the action of the lifting ribs. The force exerted during the hitting process causes the containing cavity to open and release the clothes treatment agent.

[0057] Specifically, the laundry ball 100 includes a first shell 1 and a second shell 2, and the first shell 1 and the second shell 2 are connected to each other to form a receiving cavity;

[0058] During the washing process, the first housing 1 and the second housing 2 are at least partially separated under the action of an external force, releasing the laundry treatment agent;

[0059] The addition discharge port 3 is arranged on the first shell 1 .

[0060] The scheme of this embodiment is specifically that the washing ball 100 includes a first shell 1 and a second shell 2, and the first shell 1 and the second shell 2 are connected to each other to form a receiving cavity. The first shell 1 and the second shell 2 are both hemispherical structures and are both open. Among them, the lower end of the first shell 1 is open, and the upper end has an addition discharge port 3. The second shell 2 is arranged below the first shell 1, the upper part of the second shell 2 is an open structure, the side wall 4 is an arc structure, and the bottom wall is a circular structure parallel to the horizontal plane. In other words, the washing ball 100 is a spherical structure as a whole, the upper end of the spherical structure has an addition discharge port 3, and the bottom wall of the lower end is a circular structure parallel to the horizontal plane. The connection position of the first shell 1 and the second shell 2 is arranged parallel to the addition discharge port 3. Since the bottom wall of the second shell 2 is a structure parallel to the horizontal plane, when the user puts the clothing treatment agent into the receiving cavity, the washing ball 100 can be fixed on the operating table without the user's hand. A connection structure is arranged at the open position of the first shell 1 and the second shell 2. During the washing process, the connection between the first shell 1 and the second shell 2 is at least partially separated under the action of external force, releasing the laundry treatment agent.

[0061] In another solution of this embodiment, the laundry ball 100 includes a first shell 1 and a second shell 2, and the first shell 1 and the second shell 2 are connected to each other to form a receiving cavity;

[0062] During the washing process, the first housing 1 and the second housing 2 are separated under the action of external force to release the laundry treatment agent;

[0063] The addition discharge port 3 is arranged on the first shell 1 and the second shell 2 .

[0064] In this solution, the first shell 1 and the second shell 2 are both hemispherical structures, and the addition and discharge port 3 is arranged on the first shell 1 and the second shell 2. The laundry ball 100 is a spherical structure as a whole, and the upper end of the spherical structure has the addition and discharge port 3, and the bottom wall of the lower end is a circular structure parallel to the horizontal plane. In other words, the connection position of the first shell 1 and the second shell 2 passes through the addition and discharge port 3 and is arranged vertically to the addition and discharge port 3.

[0065] The solution provided in this embodiment also includes: the first shell 1 and the second shell 2 are both open; the addition discharge port 3 is arranged on the first shell 1 and is arranged opposite to the opening of the first shell 1;

[0066] The first housing 1 is provided with a groove 7 at the open position thereof;

[0067] The second housing 2 is provided with a protruding structure 8 at the open position thereof;

[0068] The protruding structure 8 on the second housing 2 is inserted into the groove 7 on the first housing 1 for connection.

[0069] The groove 7 is formed by the outer surface of the first shell 1 being recessed toward the central axis of the washing ball 100;

[0070] The protruding structure 8 is formed by the second shell 2 protruding toward the central axis direction of the washing ball 100.

[0071] like Figures 2 to 4 As shown, the first shell 1 and the second shell 2 are both hemispherical structures and are both open. Among them, the addition and discharge port 3 is arranged on the first shell 1 and is arranged opposite to the opening of the first shell 1. That is to say, the lower end of the first shell 1 is open, and the upper end has the addition and discharge port 3. At the open position of the first shell 1, the thickness of the peripheral wall of the first shell 1 increases, and a groove 7 with an opening toward the surface of the first shell 1 is extended in the direction of the central axis of the washing ball 100. Specifically, at the open end of the first shell 1, the first shell 1 first extends vertically in the direction of the central axis of the washing ball 100 to form a first groove wall 701, and at the extended end of the first groove wall 701 and perpendicular to the first groove wall 701, it continues to extend toward the bottom wall of the second shell 2 to form a second groove wall 702, and at the end of the second groove wall 702, it is parallel to the first groove wall 701 and extends toward the surface of the first shell 1 to form a third groove wall 703. The shell side wall 4 of the open end of the second shell 2 is extended in the direction of the central axis of the washing ball 100 and is provided with a protruding structure 8. When in use, the protruding structure 8 on the second shell 2 is inserted into the groove 7 on the first shell 1 so that the first shell 1 and the second shell 2 are connected to form a receiving cavity.

[0072] The solution of this embodiment also includes: the hardness of the first shell 1 and the hardness of the second shell 2 are different;

[0073] The first shell 1 and / or the second shell 2 is deformed by external force, the protrusion structure 8 escapes from the groove 7, and the first shell 1 and the second shell 2 are separated to release the laundry treatment agent.

[0074] In another scheme of the present embodiment, by respectively providing internal threads and external threads on the first shell 1 and the second shell 2, during the washing process of the drum washing machine, the clothes squeeze the first shell 1 and / or the second shell 2, causing them to deform and causing the first shell 1 and the second shell 2 to produce different deformation amounts, and the internal threads and external threads connected thereto are separated to form an opening for releasing the clothing treatment agent. When the deformation is too large, the internal threads and the external threads are completely separated, thereby achieving the release of the clothing treatment agent by squeezing the first shell 1 and / or the second shell 2 by the clothes during the washing process of the drum washing machine.

[0075] In the solution of this embodiment, the first shell 1 and the second shell 2 of the laundry ball 100 have different hardnesses. When the first shell 1 and the second shell 2 have different hardnesses, the first shell 1 and the second shell 2 will have different deformation amounts when subjected to the same force. When the deformation amounts are one larger and one smaller, the protruding structure 8 on the second shell 2 will come out of the groove 7 on the first shell 1, and the first shell 1 and the second shell 2 will be partially separated to release the laundry treatment agent.

[0076] In one solution of this embodiment, the laundry ball 100 is made of an elastic soft material, and the first shell 1 and the second shell 2 are two materials with different hardness and large friction coefficient. Among them, the hardness of the first shell 1 is greater than that of the second shell 2. Since the hardness of the second shell 2 is relatively small, the deformation under the force during the washing process is relatively large, so the protrusion structure 8 on the second shell 2 extends from the groove 7 structure on the first shell 1, the first shell 1 and the second shell 2 are opened, and the clothing treatment agent in the accommodating cavity is released in the washing drum. In other words, the laundry ball 100 is broken by being hit inside the washing drum, or is squeezed and deformed and broken, thereby releasing the clothing treatment agent.

[0077] As a preferred solution of this embodiment, the hardness of the first shell 1 is less than the hardness of the second shell 2;

[0078] The first shell 1 is squeezed by an external force and deformed to reduce the volume of the accommodating cavity, and the protruding structure 8 extends out from the groove 7, and the first shell 1 and the second shell 2 are separated to release the laundry treating agent.

[0079] The first shell 1 and the second shell 2 of the laundry ball 100 have different hardnesses. In this embodiment, the laundry ball 100 is made of an elastic soft material, and the first shell 1 and the second shell 2 are two materials with different hardnesses and large friction coefficients. Among them, the hardness of the first shell 1 is less than that of the second shell 2. Since the hardness of the first shell 1 is relatively small, the deformation under the force during the washing process is relatively large, so the protrusion structure 8 on the second shell 2 is removed from the groove 7 structure on the first shell 1, the first shell 1 and the second shell 2 are opened, and the clothing treatment agent in the accommodating cavity is released in the washing drum. In other words, the laundry ball 100 is broken by being hit inside the washing drum, or is squeezed and deformed to break, thereby releasing the clothing treatment agent.

[0080] In the above solution, the first shell 1 and the second shell 2 of the laundry ball 100 are both made of elastic soft materials, but the hardness of the first shell 1 is less than that of the second shell 2. Therefore, under the external force, the deformation of the first shell 1 is greater than that of the second shell 2. As a result, the protrusion structure 8 on the second shell 2 is disengaged from the groove 7 structure on the first shell 1, and the first shell 1 and the second shell 2 are separated.

[0081] In another solution of this embodiment, only the first shell 1 is made of elastic soft material, while the second shell 2 is made of hard material. In this solution, the protruding structure 8 on the second shell 2 is easier to extend from the groove 7 in the first shell 1.

[0082] Of course, in other schemes of this embodiment, a protrusion structure 8 extending in the direction of the central axis of the washing ball 100 may be provided at the open position of the first shell 1, and a groove 7 extending in the direction of the central axis of the washing ball 100 and opening toward the surface of the first shell 1 may be provided at the open position of the second shell 2. The hardness of the first shell 1 is set to be greater than the hardness of the second shell 2; the second shell 2 is deformed by external force to reduce the volume of the accommodating cavity, the protrusion structure 8 extends from the groove 7, and the first shell 1 and the second shell 2 are separated to release the laundry treatment agent.

[0083] The laundry ball 100 provided in this embodiment will be hit or squeezed by clothes as the washing drum rotates during the washing process. Under the above-mentioned force, the shell of the laundry ball 100 will be deformed, and the accommodating cavity will be deformed, so that the first shell 1 and the second shell 2 of the laundry ball 100 are separated to release the laundry treatment agent. Since the accommodating cavity is in an open state, the laundry treatment agent can more easily flow from the accommodating cavity into the washing drum. In addition, the washing water will also flush the accommodating cavity, so that the detergent in the accommodating cavity can completely enter the washing drum. This solution can avoid the residue of laundry treatment agent in the accommodating cavity of the laundry ball 100, thereby ensuring the washing effect.

[0084] The solution of this embodiment also includes: the first shell 1 also has an opening, and the opening is arranged opposite to the open end of the first shell 1;

[0085] A side wall 4 is formed by extending obliquely from the opening of the first shell 1 toward the inside of the washing ball 100 and gradually approaching the central axis of the washing ball 100, and the extended end of the side wall 4 surrounds the addition and discharge port 3.

[0086] The first shell 1 also has an opening arranged opposite to the opening of the first shell 1. The opening is arranged at the lower end of the first shell 1, and the opening is arranged at the upper end of the first shell 1. In other words, the upper end of the first shell 1 has an opening, and a side wall 4 is formed by extending obliquely from the opening of the first shell 1 toward the inside of the washing ball 100 and gradually approaching the central axis of the washing ball 100, and the extended end of the side wall 4 surrounds the addition discharge port 3.

[0087] The laundry ball 100 provided in this embodiment has a side wall 4, and the extended end of the side wall 4 forms an addition and discharge port 3. Compared with the laundry ball 100 directly opened, the side wall 4 can prevent the detergent in the accommodating cavity from being spilled out from the addition and discharge port 3 in large quantities when the laundry ball 100 is placed in the washing drum.

[0088] The solution of this embodiment also includes: at least one guide wall 5 is formed by extending from the addition discharge port 3 on the first shell 1 to the bottom of the second shell 2 .

[0089] Specifically, the guide wall 5 has scale lines.

[0090] The laundry ball 100 provided in this embodiment further includes a guide wall 5, which is formed by extending vertically from the addition and discharge port 3 on the first shell 1 to the bottom of the second shell 2. The guide wall 5 has scale lines.

[0091] In the above scheme, since the guide wall 5 is provided, when the user adds the laundry treatment agent to the accommodating chamber, the laundry treatment agent enters the accommodating chamber through the addition and discharge port 3 along the guide wall 5, thereby preventing the laundry treatment agent from splashing. Also, since the guide wall 5 is provided with scale lines, the user can accurately grasp the dosage of the laundry treatment agent added. During use, the user can determine the amount of laundry treatment agent to be added according to information such as the number of different laundry items to be washed each time, and stop adding the laundry treatment agent when it reaches a certain scale line. This can avoid the situation in which too much laundry treatment agent is added during washing, resulting in too much foam and incomplete washing, and too little laundry treatment is added, resulting in incomplete washing.

[0092] In another solution of this embodiment, a plurality of guide walls 5 are arranged at intervals along the circumference of the addition discharge port 3 .

[0093] In another solution of this embodiment, the guide wall 5 is formed by extending obliquely from the addition and discharge port 3 on the first shell 1 toward the side wall 4 of the second shell 2 .

[0094] The solution provided in this embodiment also includes: a liquid through hole 6 is provided on the side wall 4 .

[0095] In this solution, a plurality of liquid holes 6 are arranged at intervals on the side wall 4 of the first housing 1. Due to the arrangement of the liquid holes 6, even if the accommodating chamber is occasionally not opened, the laundry treatment agent in the washing ball can be discharged from the accommodating chamber through the addition discharge port 3 and the liquid holes 6.

[0096] As a preferred solution of this embodiment, the liquid through hole 6 is arranged at an end of the side wall 4 away from the addition discharge port 3.

[0097] In this solution, during the washing process, even if the first shell 1 and the second shell 2 of the washing ball 100 are not separated, when the washing ball 100 is turned over to an inverted position in the washing tub, the laundry treatment agent will be released into the washing tub through the liquid hole 6. This solution further ensures that the laundry treatment agent can be smoothly put into the washing tub.

[0098] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
