Description

Technical Field

[0001] The present application relates to the technical field of washing machines, and in particular to a water inlet bellows and a washing device. Background Art

[0002] In the drum washing machine structure, when a straight pipe is used for water injection, the installation space is limited, resulting in a pipe section that is too small, the water injection flow path is restricted, and the water injection effect is poor.

[0003] In order to solve the problem of poor water injection effect of straight pipe water injection, the relevant technology uses a bellows to inject water into the washing machine. Since the bellows has a certain compression amount and is easy to bend and easy to install, it is widely used.

[0004] The water inlet bellows connects the powder box to the outer drum. During the spin cycle, the outer drum vibrates significantly, which in turn drives the bellows to vibrate. This creates significant friction between the bellows and the outer drum wall, shortening its service life and reducing the user experience. Summary of the Invention

[0005] The present application provides a water inlet bellows and a washing device to solve the problem that the vibration of the outer barrel drives the bellows, causing friction between the bellows and the outer barrel and reducing the service life.

[0006] In a first aspect, the present application provides a water inlet bellows, comprising: a first connecting section, a corrugated section, and a second connecting section; one end of the first connecting section is connected to the water inlet pipe via the corrugated section; the other end of the first connecting section is connected to a washing tub via the second connecting section; the corrugated section is inclined relative to an extension line of the central axis of the water inlet pipe in a direction away from the washing tub; the inclination angle of the corrugated section is greater than or equal to an avoidance angle, which is an angle at which the outer wall of the corrugated section can contact the outer wall of the washing tub.

[0007] Optionally, the inclination angle of the corrugated segment is 10° to 20°.

[0008] Optionally, the corrugated section, the first connecting section, and the second connecting section are integrally formed.

[0009] Optionally, the corrugated section includes a plurality of corrugated rings, and the number of the corrugated rings is 4 to 8.

[0010] Optionally, the first connecting section is connected to the second connecting section through the rotating section.

[0011] Optionally, the rotating section is a U-shaped cavity or a V-shaped cavity; the angle between the central axis of the first connecting section and the central axis of the second connecting section is 20° to 50°.

[0012] Optionally, the bottom surface of the rotating section is a rounded structure or a flat structure.

[0013] Optionally, the water inlet bellows further includes a water retaining rib; one end of the water retaining rib is connected to the inner wall of the turning section and extends toward the bottom surface of the turning section, and the other end of the water retaining rib is spaced apart from the bottom surface of the turning section.

[0014] Optionally, the connecting member is provided on the outer wall of the rotating section or on the end of the second connecting section facing away from the first connecting section.

[0015] A second aspect of the present application provides a washing device, comprising the water inlet bellows provided in the first aspect, and also comprising a washing tub, wherein the washing tub is connected to the water inlet bellows.

[0016] The water inlet bellows and washing machine provided herein comprise a plurality of interconnected bellows sections, a first connecting section, and a second connecting section. The bellows sections are tilted at a predetermined angle relative to the extended central axis of the water inlet pipe, and are tilted away from the washing tub. Specifically, the tilt angle is greater than the avoidance angle. This avoids contact between the bellows sections and the washing tub, preventing vibration of the washing tub from interfering with the bellows sections and preventing them from contacting the washing tub during vibration. By providing a bellows section with an inclination angle greater than the avoidance angle, the service life of the bellows sections can be effectively extended, thereby extending the service life of the water inlet bellows and reducing production costs.

[0025] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0026] Among washing machine accessories, the water inlet pipe used to supply washing water to the washing tub is typically a bellows. Bellows are widely used due to their simple installation, wide adaptability, and low cost. Furthermore, their inherent corrugated structure provides them with certain compression and resilience properties, providing a certain vibration reduction effect. However, during operation, such as during the spin cycle, the bellows vibrates with the washing tub, causing friction and self-abrasion.

[0027] If this phenomenon persists for a long time, the worn portion of the bellows will be damaged, leading to water leakage, requiring the user to replace the bellows at regular intervals. Furthermore, the damaged bellows will generate a loud noise when vibrating, seriously affecting the user experience. The embodiment of the present application sets an inclination angle for the bellows section, allowing the bellows to avoid friction with the washing tub and itself, thereby extending the service life of the bellows.

[0028] See also Figure 1 , is a schematic diagram of the three-dimensional structure of a water inlet bellows in an embodiment of the present application.

[0029] The water inlet bellows provided herein includes a first connecting section 10, a second connecting section 30, and a bellows section 20. The first connecting section 10 is connected to the bellows section 20 and the second connecting section 30 at both ends, respectively. The end of the bellows section 20 facing away from the first connecting section 10 is connected to the water inlet pipe, and the end of the second connecting section 30 facing away from the first connecting section 10 is connected to the washing tub. In other words, when water enters the washing tub, it passes through the water inlet pipe, the bellows section 20, the first connecting section 10, and the second connecting section 30 in sequence.

[0030] The corrugated section 20 has a certain inclination angle relative to the extension line of the central axis of the water inlet pipe, and is inclined in the direction away from the washing tub. Specifically, the inclination angle is greater than or equal to the avoidance angle. The avoidance angle is the angle at which the outer wall of the corrugated section 20 contacts the outer wall of the washing tub. In other words, the corrugated section 20 with an inclination angle is provided precisely to avoid contact between the corrugated section 20 and the washing tub. It is understandable that when installing the water inlet bellows, if the outer wall of the corrugated section 20 fits tightly against the outer wall of the washing tub, then during the stage of large amplitude of the washing tub, such as the spin-drying stage of the washing tub, due to the large amplitude of the washing tub, the corrugated section 20 connected thereto will collide with the washing tub during the vibration process and generate friction.

[0031] By avoiding contact between the bellows section 20 and the washing tub, the bellows section 20 self-compresses and vibrates synchronously with the tub when the tub vibrates. It can be understood that during this synchronous vibration, the bellows section 20 does not interfere with the tub and, therefore, does not rub against it. In other words, the bellows section 20 does not rub against the tub due to vibration. Furthermore, the inclination angle of the bellows section 20 and its inherent corrugated structure mitigate self-abrasion, extending its service life.

[0032] It is understandable that if the corrugated section 20 is subjected to long-term vibration and self-abrasion, or friction with the washing tub, water leakage will inevitably occur at the same location due to long-term wear and tear, requiring regular replacement of the water inlet bellows. This not only shortens the service life of the water inlet bellows, but also increases production costs. Therefore, by providing the corrugated section 20 with an inclination angle greater than or equal to the avoidance angle, the service life of the corrugated section 20 can be effectively extended while reducing production costs.

[0033] For example, the inclination direction of the corrugated section 20 is toward the direction away from the washing tub. At the same time, the installation space of the water inlet bellows needs to be considered to avoid occupying unnecessary space and causing the overall volume to be too large.

[0034] For example, Figure 1 As shown, with the right side of the figure as the right, the first connecting section 10 and the corrugated section 20 are arranged on the left, and the second connecting section 30 is arranged on the right. Of course, during actual use and installation, the positional relationship between the first corrugated section 20 and the second corrugated section 20 needs to be determined based on the structure of the entire machine and the specific position of the washing tub.

[0035] In some embodiments, the inclination angle of the corrugated section 20 is 10° to 20°. In other words, the angle between the central axis of the corrugated section 20 and the central axis of the water inlet pipe is 10° to 20°.

[0036] Figure 3 This is a schematic diagram of the three-dimensional structure of the water inlet bellows in the embodiment of the present application.

[0037] For example, Figure 1 and Figure 3 As shown, with the right side of the figure as the right, the washing tub is positioned on the right side, and the corrugated section 20 is tilted toward the front or left side of the washing tub to avoid friction with the washing tub. The tilt angle is set between 10° and 20°. This is primarily due to the consideration that if the tilt angle is too small, the distance between the corrugated section 20 and the washing tub will be too small, causing friction. If the tilt angle is too large, the distance between the corrugated section 20 and the washing tub will be too large, not only occupying excessive installation space, but also affecting water inlet efficiency. Therefore, setting the tilt angle between 10° and 20° ensures that friction between the corrugated section 20 and the washing tub is eliminated, without affecting water inlet efficiency, while also saving installation space.

[0038] The inclination angle is 10° to 20°, and the specific angle is adjusted according to the outer diameter of the corrugated section 20 and the size of the first connecting section 10 .

[0039] For example, the tilt angles are 12°, 15°, and 18°. Of course, the tilt angles are not limited to the example angles.

[0040] In some embodiments, the corrugated section 20, the first connecting section 10, and the second connecting section 30 are integrally formed. In other words, the water inlet bellows is integrally formed. This integrally formed water inlet bellows ensures the connection strength between the corrugated section 20, the first connecting section 10, and the second connecting section 30. Furthermore, this integrally formed arrangement provides the water inlet bellows with excellent mechanical properties, extending the service life of the water inlet bellows section 20.

[0041] For example, the corrugated section 20, the first connecting section 10, and the second connecting section 30 adopt an integrally formed structure, and only one set of molds is needed to achieve mass production, which simplifies the production process and saves costs.

[0042] In some embodiments, the corrugated section 20 includes multiple corrugated rings, with the number of corrugated rings ranging from 4 to 8. The specific number of corrugated rings is related to the compression amount. Since the vibration reduction effect of the corrugated section 20 is mainly related to the compression amount, the greater the compression amount, the better the vibration reduction effect. If the number of corrugated rings is too small, the compression effect will not be sufficient. If the number of corrugated rings is too large, it will not only cause self-wear, but may also cause self-wear during the vibration process. Therefore, setting the number of corrugated rings between 4 and 8 can prevent self-wear of the corrugated section 20 while ensuring the compression effect, and at the same time help save production costs.

[0043] It is understood that the outer diameter of the corrugated ring is the main factor affecting the tilt angle. It is also understood that the distance between the corrugated section 20 and the washing tub depends on the distance between the outer diameter of the corrugated ring and the washing tub. Therefore, the tilt angle of the corrugated section 20 can be reasonably set according to the outer diameter of the corrugated ring.

[0044] Specifically, the number of bellows can be 5, 6, or 7. The number of bellows can be adjusted to suit different water inlet bellows requirements. For example, when the height of the water inlet bellows is ample, 6 or 7 bellows can be used to increase compression. For example, when the height of the water inlet bellows is relatively compact, 5 or 6 bellows can be used, and the outer diameter of the bellows can be increased accordingly to increase compression. The specific number of bellows can be adjusted adaptively based on actual application conditions, installation space, and other parameters.

[0045] For example, Figure 1 As shown, there are 6 corrugated rings.

[0046] For example, Figure 1 As shown, the corrugated ring is a structure in which the middle position protrudes compared to the upper and lower positions, and the outer diameter of the middle position is larger than the outer diameter of the upper and lower positions. As a result, when the corrugated ring is compressed, the upper and lower parts will move toward the middle position, and when the external force disappears, the upper and lower parts will return to their initial positions. Therefore, during the vibration of the corrugated section 20, the self-wear phenomenon of the corrugated section 20 is slowed down due to the reciprocating motion of the upper and lower parts.

[0047] In some embodiments, the water inlet bellows further includes a revolving section 40 disposed between the first connecting section 10 and the second connecting section 30, connecting the first connecting section 10 and the second connecting section 30 via the revolving section 40. Specifically, the revolving section 40 is integrally formed with the first connecting section 10 and the second connecting section 30, ensuring the strength of the connection between the revolving section 40 and the first and second connecting sections 10 and 30, thereby preventing the self-abrasion phenomenon that occurs in the connecting pipes on both sides of a conventional U-shaped water inlet pipe. The revolving section 40 serves as a transitional connection between the first and second connecting sections 10 and 30.

[0048] In some embodiments, the rotating section 40 is a U-shaped cavity or a V-shaped cavity. By setting up the U-shaped cavity or the V-shaped cavity rotating section 40, the washing water in the first connecting section 10 can smoothly enter the second connecting section 30 and then be introduced into the washing tub through the second connecting section 30, thereby avoiding the washing water in the first connecting section 10 from impacting the second connecting section 30. The U-shaped cavity or the V-shaped cavity plays a certain buffering role.

[0049] The U-shaped or V-shaped cavity can both provide a buffering effect on the washing water and can be adaptively adjusted according to the actual installation space. Specifically, by providing a U-shaped or V-shaped cavity, the water supply path for the washing water can be increased while also saving installation space for the water inlet bellows.

[0050] Specifically, the angle between the central axis of the first connecting section 10 and the central axis of the second connecting section 30 is 20° to 50°. The angle between the central axis of the first connecting section 10 and the central axis of the second connecting section 30 can be understood as the angle of the upper position of the rotating section 40 of the U-shaped cavity or the V-shaped cavity. If the angle between the central axis of the first connecting section 10 and the central axis of the second connecting section 30 is too large, the distance between the first connecting section 10 and the second connecting section 30 will be too large, and the first connecting section 10 and the second connecting section 30 will occupy unnecessary installation space, resulting in a waste of installation space for the water inlet bellows and affecting the overall volume; if the angle between the central axis of the first connecting section 10 and the central axis of the second connecting section 30 is too small, the distance between the first connecting section 10 and the second connecting section 30 will be too small, so that the corrugated section 20 is set close to the washing tub, which will cause contact between the corrugated section 20 and the washing tub and generate friction. Therefore, the angle is set to 20° to 50° to ensure that the corrugated section 20 does not generate friction with the washing tub and reasonably utilize the installation space of the water inlet bellows.

[0051] For example, the angles between the central axis of the first connecting section 10 and the central axis of the second connecting section 30 are 30°, 35°, or 40°.

[0052] In some embodiments, the bottom surface of the turning section 40 is a rounded structure or a flat structure. Specifically, the bottom structure of the turning section 40 is used to buffer and store water flow, and is therefore configured to be a relatively smooth structure.

[0053] For example, the bottom surface of the rotating section 40 is configured as a rounded structure to guide water flow and reduce impact. The bottom surface of the rotating section 40 is configured as a flat structure to increase the water storage capacity of the rotating section 40.

[0054] Specifically, the arrangement of the bottom of the rotary section 40 can be adaptively adjusted according to the actual size parameters of the water inlet bellows and the operating conditions.

[0055] Figure 4 This is a perspective view of the water inlet bellows provided in an embodiment of the present application. It can be seen that a water retaining rib 50 is provided inside the water inlet bellows. Figure 5 for Figure 4 A partial enlarged view of point A.

[0056] like Figure 4 and Figure 5As shown, the water inlet bellows also includes a water retaining rib 50, which is arranged in the rotating section 40, and one end of the water retaining rib 50 is connected to the inner wall of the rotating section 40, and the other end extends toward the bottom of the rotating section 40 and has a certain distance from the bottom surface of the rotating section 40. Washing water can be conducted between the water retaining rib 50 and the bottom of the rotating section 40.

[0057] By setting the water retaining rib 50, the main unit can play a role in blocking water. On the one hand, it can relieve the buffering pressure of washing water. On the other hand, when the water inlet bellows is used in a washing device with clothing care function, the water retaining rib 50 is set and used to perform water sealing to prevent hot steam from conducting in reverse.

[0058] For example, Figure 4 As shown, the water retaining rib 50 extends downward along the inner walls of the first connecting section 10 and the second connecting section 30 at both ends of the turning section 40. It can be seen that the water retaining rib 50 is a similar curved tubular structure. It is understood that the water retaining rib 50 can also be directly set in a recessed position on the upper portion of the turning section 40 and extend downward through the recessed position. Similarly, the water retaining rib 50 can be configured as a tubular curved structure, a plate-like curved structure, a straight plate-like structure, or a curved surface structure, as long as it can perform the water retaining function. The specific structural form of the water retaining rib 50 is not specifically limited here.

[0059] For example, the water retaining rib 50 can be configured as a structure integrally formed with the rotating section 40 or with the first connecting section 10 and the second connecting section 30, thereby ensuring the connection strength between the water retaining rib 50 and the rotating section 40 or with the first connecting section 10 and the second connecting section 30. Of course, the water retaining rib 50 can be configured as a structure that is detachable from the rotating section 40 or with the first connecting section 10 and the second connecting section 30, thereby facilitating replacement and maintenance of the water retaining rib 50.

[0060] For example, when the water inlet bellows is used in a washing and care machine, hot steam from drying clothes may circulate in the reverse direction through the second connecting section 30, the first connecting section 10, and the corrugated section 20. This not only wastes hot steam but also shortens the service life of the water inlet bellows due to prolonged contact with hot steam. By providing a water retaining rib 50, the washing water is retained at the bottom of the water inlet bellows. The liquid surface of the washing water contacts the water retaining rib 50, preventing the hot steam from passing through the rotating section 40. This acts as a water seal, preventing the reverse circulation of hot steam and improving the drying effect on clothes.

[0061] For example, the U-shaped or V-shaped cavity plays a certain auxiliary role in the water sealing process of the water retaining rib 50. Compared with ordinary cylindrical water pipes, the bottom of the U-shaped or V-shaped cavity has a larger water storage capacity. Therefore, during the reflux of hot steam, the driving force of the hot steam reflux is less than the gravity of the washing water at the bottom of the U-shaped or V-shaped cavity. Therefore, the hot steam cannot flow back to the first connecting section 10 or even back to the position of the corrugated section 20 through the washing water. This acts as a water seal, not only improving the drying effect of clothes, but also extending the service life of the water inlet bellows.

[0062] In some embodiments, the water inlet bellows further includes a connector 60, which is primarily used to secure the water inlet bellows. The water inlet bellows section 20 is secured to the washing tub or other component to be mounted via the connector 60. The connector 60 can be disposed at the bottom of the rotating section 40 or at the end of the second connecting section 30 facing away from the first connecting section 10, i.e., the end where the second connecting section 30 connects to the washing tub.

[0063] For example, Figure 1 As shown, the connecting member 60 is arranged at the bottom position of the rotating section 40. At the same time, the connecting member 60 is in the form of a screw column. By inserting a screw into the connecting member 60, the water inlet bellows can be fixed.

[0064] For example, Figure 4 As shown, the connecting member 60 is provided at the end portion where the second connecting section 30 is connected to the washing tub, and is also in the form of a screw column.

[0065] For example, the connecting member 60 is integrally formed with the rotating section 40 or the second connecting section 30 .

[0066] It is understandable that the connecting member 60 is not limited to the form of a screw column, and of course it can also be in other forms, as long as it can play a connecting role. The specific setting form of the connecting member 60 is not specifically limited here, and can be adaptively adjusted according to the actual size of the water inlet bellows.

[0067] For example, the connecting member 60 may be a buckle, and a slot is provided at the position where the washing tub is connected to the second connecting section 30 , and the connection between the corrugated water inlet pipe and the washing tub is achieved through the cooperation between the buckle and the slot.

[0068] Figure 2 This is a left view of a water inlet bellows in an embodiment of the present application.

[0069] like Figure 2As shown, the water inlet bellows also includes a buffer pad 70, which is arranged on the back of the first connecting section 10, that is, the side of the first connecting section 10 close to the washing tub. The buffer pad 70 makes the first connecting section 10 contact with the washing tub, thereby buffering the vibration of the water inlet bellows caused by the vibration of the washing tub, further ensuring the stability of the water inlet bellows, and reducing the noise caused by the vibration of the water inlet bellows.

[0070] For example, the buffer pad 70 and the first connecting section 10 are integrally formed.

[0071] For example, the buffer pad 70 is arranged at one end of the first connecting section 10 close to the corrugated section 20, so that the buffer pad 70 is located in the middle of the entire water inlet corrugated section 20, which is beneficial to the installation stability of the water inlet bellows.

[0072] An embodiment of the present application also provides a washing device, including the water inlet bellows provided by any of the above embodiments, and therefore has all the beneficial technical effects of the water inlet bellows in any of the above embodiments, which will not be repeated here.

[0073] The washing device further includes a washing tub, which is connected to the water inlet bellows. Specifically, the washing tub is connected to the second connecting section 30 of the water inlet bellows, thereby conducting the washing water in the second connecting section 30 into the washing tub.

[0074] For example, the washing device may be a washing machine, an all-in-one washing and care machine, etc.

[0075] When the water inlet bellows is used in a washing and care machine, the water retaining rib 50 structure provided can play a water sealing role during the process of drying clothes in the washing and care machine.

[0076] The water inlet bellows and washing machine provided in the embodiments of the present application are provided with a corrugated section 20 arranged obliquely relative to the washing tub. The angle of inclination of the corrugated section 20 is greater than or equal to the clearance angle for contact with the washing tub. By providing the corrugated section 20 with an angle greater than or equal to the clearance angle, friction between the corrugated section 20 and the tub wall is avoided, as well as wear of the corrugated section 20 caused by long-term vibration. This effectively extends the service life of the corrugated section 20, thereby extending the service life of the water inlet bellows, while also reducing production costs.

[0077] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without expending creative work shall fall within the scope of protection of this application.
