Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an inner drum structure and a washing machine. Background Art

[0002] Washing machines use detergents and water to wash, rinse, and spin dry clothes. Washing machines can be roughly divided into pulsator type, stirring type, and drum type washing machines. In a drum type washing machine, a water tank for containing washing water is installed inside the shell, a drum for containing washings is arranged inside the water tank, and a motor and shaft for rotating the drum are arranged on the back of the water tank. The drum type washing machine uses the friction between the washing water stored in the water tank and the washings in the drum, as well as the chemical action of the detergent contained in the washing water to remove the stains contained in the washings. As an important component of the washing machine, the washing drum is not only used to contain the washings and constitute a washing container, but also can participate in the washing work. In particular, the drum washing machine mainly relies on the rotation of the washing drum to lift and throw the clothes to form a throwing effect. At the same time, the washing drum also has a certain rubbing effect on the clothes, thereby relying on throwing and washing to create a washing effect.

[0003] Traditional European drum washing machines have the advantages of saving water and energy. On this basis, top-opening drum washing machines open the door at the top of the inner drum, so users can put and take clothes without bending over. However, the shape of existing top-opening drums is mostly cylindrical. During the dehydration and drying steps of the washing machine, the kinetic energy of the inner drum and the clothes increases, and the uneven distribution of clothes can easily cause the inner drum to be too eccentric and hit the outer shell, resulting in a short service life of the washing machine and a poor user experience. Utility Model Content

[0004] Based on the above problems, the purpose of the utility model is to provide an inner drum structure and a washing machine, which can prevent the inner drum from colliding with the outer shell due to excessive eccentricity, and the washing machine has a long service life and a good user experience.

Among them, the terms "first position" and "second position" are two different positions.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 4 As shown, this embodiment provides an inner cylinder structure, which includes an inner cylinder body 1 and a door body 2. The inner cylinder body 1 includes a first mounting portion 11, a second mounting portion 12 and a bearing portion 13. The bearing portion 13 is a symmetrical structure. The first mounting portion 11 and the second mounting portion 12 are symmetrically arranged on both sides of the bearing portion 13. The bearing portion 13 is provided with a first guide surface 131, a second guide surface 132 and a bearing surface 133. The first guide surface 131 and the second guide surface 132 are symmetrically arranged on both sides of the bearing surface 133. The bearing surface 133 is used to carry clothes. When the inner cylinder structure rotates, the first guide surface 131 and the second guide surface 132 can guide the clothes to the bearing surface 133. The door body 2 is arranged on the bearing portion 13, and is used to open or close the inner cavity of the inner cylinder body 1, so as to facilitate users to take and put clothes in the inner cavity of the inner cylinder body 1.

[0033] During the dehydration and spin-drying stage of the washing machine, the rotation speed of the inner drum structure is relatively high, and the clothes in the inner drum body 1 are concentrated on the bearing surface 133 of the bearing part 13 under the guidance of the first guide surface 131 and the second guide surface 132 of the bearing part 13. Since the bearing part 13 is a symmetrical structure, and the first guide surface 131 and the second guide surface 132 are symmetrically arranged on both sides of the bearing surface 133, the clothes on the bearing surface 133 are in the middle position of the entire inner drum structure at this time. The overall anti-eccentricity ability of the inner drum structure is strong, which avoids the inner drum from hitting the outer shell due to excessive eccentricity. The washing machine has a long service life and a good user experience. The door body 2 is designed on the bearing part 13 of the inner drum structure, and a top-opening door method is adopted to take and put clothes. The user does not need to bend over to operate, which improves the user experience.

[0034] For the convenience of processing, optionally, the cross-sections of the first guide surface 131, the second guide surface 132 and the bearing surface 133 are spliced ​​to form a semicircle. In other words, the first guide surface 131, the second guide surface 132 and the bearing surface 133 can be a whole smooth arc surface, which avoids the loss of kinetic energy due to large friction with the clothes, and the washing noise is low, which improves the user experience. It is understandable that the clothes are mainly concentrated on the bearing surface 133 under the guidance of the first guide surface 131 and the second guide surface 132. Of course, when there are more clothes, some of the clothes are retained on the first guide surface 131 and the second guide surface 132. At this time, the anti-eccentricity ability of the entire inner drum structure is still relatively strong.

[0035] In some embodiments, the cross-sections of the first guide surface 131, the second guide surface 132, and the bearing surface 133 are spliced ​​to form an isosceles trapezoid. The isosceles trapezoid is a symmetrical structure that can provide better anti-eccentricity capability. The two sides of the isosceles trapezoid are the first guide surface 131 and the second guide surface 132, respectively. The shorter bottom side of the isosceles trapezoid is the bearing surface 133, and the two ends of the longer bottom side are respectively connected to the first mounting portion 11 and the second mounting portion 12. It should be noted that the corners of the isosceles trapezoid can be connected with a chamfered structure to avoid the existence of sanitary dead corners and cause user anxiety.

[0036] Optionally, the first mounting portion 11 and the second mounting portion 12 are both circular, easy to manufacture, and convenient to align the rotation axis of the first mounting portion 11 and the second mounting portion 12, so as to ensure the installation coaxiality of the first mounting portion 11 and the second mounting portion 12, and further improve the anti-eccentricity capability. Optionally, the first mounting portion 11 is provided with a first rotating shaft 3, and the second mounting portion 12 is provided with a second rotating shaft 4, the first rotating shaft 3 is rotatably arranged in the housing of the washing machine, and the second rotating shaft 4 is connected to the motor of the washing machine. The first rotating shaft 3 can be installed on the bearing seat of the housing through a bearing to reduce the rotation friction resistance of the first rotating shaft 3. The second rotating shaft 4 can be connected to the output shaft of the motor through a coupling to ensure the continuous and stable operation of the second rotating shaft 4.

[0037] Optionally, the door body 2 is an oblong shape. It is understandable that the oblong shape is composed of a rectangle and two semicircles, and the two semicircles are respectively located on the two wide sides of the rectangle. The oblong shape of the door body 2 can enhance the technological sense of the product, and the appearance is beautiful, and the lines are smooth and natural. To facilitate the user to take and put clothes, optionally, the bearing part 13 is provided with a take-in and put-out port, and the door body 2 is movably arranged at the take-in and put-out port. When the washing program of the washing machine is finished, the take-in and put-out port is tilted upward for the user to take and put clothes. In some embodiments, the door body 2 can be opened or closed by rotating, and optionally, the door body 2 is rotatably connected to the bearing part 13 by a hinge structure. The door body 2 can be rotated in a flipping manner, and the door body 2 can also be rotated in a double-door manner. In some embodiments, the door body 2 can be opened or closed by sliding, and optionally, the door body 2 is slidably connected to the bearing part 13 by a slide rail structure. It should be noted that a sealing ring is provided between the door body 2 and the take-in and put-out port to prevent leakage of washing liquid during washing.

[0038] The present embodiment also provides a washing machine, including a shell and the above-mentioned inner drum structure, wherein the inner drum structure is arranged in the shell. In the dehydration and spin-drying stage of the washing machine, the inner drum structure rotates at a relatively high speed, and the clothes in the inner drum body 1 are concentrated on the bearing surface 133 of the bearing part 13 under the guidance of the first guide surface 131 and the second guide surface 132 of the bearing part 13. Since the bearing part 13 is a symmetrical structure, and the first guide surface 131 and the second guide surface 132 are symmetrically arranged on both sides of the bearing surface 133, the clothes on the bearing surface 133 are in the middle position of the entire inner drum structure at this time, and the overall anti-eccentricity ability of the inner drum structure is strong, which avoids the inner drum from hitting the outer shell due to excessive eccentricity, and the washing machine has a long service life and a good user experience. The door body 2 is designed on the bearing part 13 of the inner drum structure, and the clothes are taken in and out by the top-opening door method, without the need for the user to bend over to operate, thereby improving the user experience.

[0039] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
