Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model, and the following embodiments are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In the fittings of laundry treatment apparatuses, a water inlet pipe for supplying washing water into a drum assembly is generally a bellows, which has advantages of simple installation, wide adaptability, low cost, etc., and is widely used. Meanwhile, due to the corrugated structure of the corrugated pipe, the corrugated pipe has certain compression and rebound performances, and a certain vibration reduction effect is achieved. However, during the operation of the laundry treating apparatus, for example, a spin-drying stage, the bellows may vibrate with the drum assembly, and during the vibration, there may be a phenomenon of contact friction and self-abrasion with the drum assembly and the cabinet.

If the phenomenon exists for a long time, the worn position of the corrugated pipe is damaged, so that the water leakage phenomenon occurs, a user needs to replace the corrugated pipe at intervals, and meanwhile, the damaged corrugated pipe can generate larger noise when vibrating, so that the use experience of the user is seriously affected. Based on the structure, the avoidance groove for preventing interference is arranged on the corrugated ring, so that the condition that the water inlet pipeline is mechanically interfered with the outer wall of the cylinder assembly or the inner wall of the box body in the running process of the clothes treatment equipment, and water leakage caused by the damage of the corrugated ring due to friction is prevented.

Fig. 1 to 6 illustrate schematic structural views of a water intake pipe 100 for a laundry treating apparatus according to an exemplary embodiment of the present utility model.

As shown in fig. 1 to 6, the water intake pipe 100 includes a first connection pipe section 110, a bellows section 120, and a second connection pipe section 130. One end of the first connecting tube segment 110 is configured to be connected to a cartridge assembly (not shown); one end of the bellows segment 120 is configured to be connected to a water inlet assembly 200, as shown with reference to fig. 5; and both ends of the second connection pipe section 130 are connected with the first connection pipe section 110 and the bellows section 120, respectively, to form a water inlet passage from the water inlet assembly 200 to the cartridge assembly. In other words, when water is supplied into the drum assembly of the laundry treating apparatus, wash water sequentially passes through the bellows segment 120, the second connection segment 130, and the first connection segment 110 from the water outlet end of the water supply assembly 200 and then enters the drum assembly.

In some embodiments, as shown in fig. 2 to 4, the axial direction of the second connecting pipe section 130 and the axial direction of the first connecting pipe section 110 have a predetermined angle therebetween, so as to save installation space.

Bellows segment 120 includes a plurality of bellows rings, at least one of which is provided with relief groove 150 for preventing interference with component structures disposed about bellows segment 120. It should be noted that, the parameters of which one or more corrugated rings the relief groove 150 is disposed on, which direction the corrugated rings are disposed on, and the relief depth of the relief groove 150 are all determined by the positions and sizes of the components disposed around the water inlet pipe 100, which is not limited by the present utility model.

In other words, before manufacturing the water intake pipe 100, a worker may model the structure of the laundry treatment apparatus using three-dimensional modeling simulation software to obtain the relative positional relationship between the water intake pipe 100 and the components disposed around the water intake pipe 100, thereby obtaining the parameters such as which one or more corrugated rings the relief groove 150 is disposed on, in which direction of the corrugated rings, and the relief depth of the relief groove 150.

In addition, the staff can simulate the running condition of the clothes treatment equipment, so that the vibration amplitude of the water inlet pipeline 100 and parts arranged around the water inlet pipeline 100 is obtained in the running process of the clothes treatment equipment, and the setting position, the avoidance depth and other parameters of the avoidance groove 150 are more accurate.

In the above-mentioned scheme, the avoiding groove 150 is provided, so that the corrugated pipe section 120 of the water inlet pipeline 100 is not contacted with surrounding parts. In other words, the corrugated tube section 120 of the water inlet pipeline 100 does not rub with the components such as the tube assembly or the box body due to the vibration of the tube assembly, and meanwhile, due to the corrugated structure of the corrugated tube section 120, the self-grinding phenomenon of the corrugated tube section 120 is relieved, and the service life of the corrugated tube section 120 is prolonged.

It will be appreciated that the bellows segment 120 is in a vibration self-grinding or friction environment with the barrel assembly for a long period of time, and the water leakage phenomenon inevitably occurs at the same position due to long-time abrasion, so that the water inlet bellows needs to be replaced regularly, which not only affects the service life of the water inlet bellows, but also increases the production cost. Therefore, by providing the relief groove 150, the service life of the bellows segment 120 can be effectively prolonged, while reducing the production cost.

In addition, the avoidance groove 150 can avoid occupying unnecessary space, and the aim of reducing the whole volume of the clothes treatment equipment is fulfilled.

In the present utility model, the number of the bellows rings of the bellows segment 120 can be adaptively adjusted according to practical application conditions, installation space size, and other parameters. Alternatively, the number of corrugated rings may be 4, 5, 6 or 7. As an example, when the laundry treating apparatus is a floor-type drum washing machine, the installation space of the water inlet pipe 100 in the height direction is sufficient, and 6 or 7 pulsator rings may be provided, thereby increasing the compression amount. When the laundry treating apparatus is a wall-mounted drum washing machine, the installation space of the water inlet pipe 100 in the height direction is compact, and 4 or 5 pulsator rings may be provided. In addition, the outer diameter of the corrugated ring can be adjusted according to the specific condition of the actual installation space so as to improve the compression amount. By way of example, as shown in fig. 1, the bellows segment 120 of the present utility model is provided with 4 bellows loops.

It will be understood that, as shown in fig. 2 to 4, the bellows ring has a structure in which the middle position is protruded compared with the upper and lower positions, and the outer diameter of the middle position is larger than that of the upper and lower positions, so that the upper and lower portions can move toward the middle position during the compression of the bellows ring, and the upper and lower portions recover to the initial position when the external force is lost, thereby slowing down the self-polishing phenomenon of the bellows section 120 due to the reciprocating movement of the upper and lower portions during the vibration of the bellows section 120. As such, the intermediate position of the bellows ring is subjected to the greatest fatigue stress, and the intermediate position of the bellows ring is easily broken.

Based on this, in the present utility model, the reinforcing ribs 140 are provided in the circumferential direction at the intermediate positions of the plurality of bellows rings of the bellows section 120 to locally reinforce the intermediate positions of the bellows rings. It should be noted that the ribs 140 protrude from the surface of the corrugated ring by a first predetermined height, which increases the thickness of the middle portion of the corrugated ring, thus not only increasing the overall strength of the corrugated pipe section 120, but also preferentially wearing the protruding ribs 140 even if the corrugated pipe section 120 rubs against the drum assembly or the tank body, without damaging the corrugated pipe section 120, and extending the service life of the water intake pipe 100. By way of example, the present utility model defines a first predetermined height having a value greater than the value of the wall thickness of the tubing of the bellows segment 120 to further increase the overall strength of the bellows segment 120.

As described above, the relative positional relationship between the water inlet pipe 100 and the components disposed around the water inlet pipe 100 can be obtained by means of three-dimensional modeling simulation, so that friction between the bellows segment 120 of the water inlet pipe 100 and other components is prevented by providing the avoiding groove 150. However, for the first or second connection pipe section 110 or 130 of the water inlet pipe 100, if friction is prevented by the same way as the formation of the avoiding structure, the inner diameter of the first or second connection pipe section 110 or 130 may be small, so that water in the water inlet assembly 200 cannot enter the cartridge assembly in time, and overflow occurs. In addition, with some laundry treatment apparatuses, there may be cases where avoidance is impossible due to insufficient space.

Based on this, as shown in fig. 3, in some embodiments of the present utility model, the first connection pipe section 110 and/or the second connection pipe section 130 is provided with the abrasion-resistant rib 160 on the side configured to face the cartridge assembly, and the abrasion-resistant rib 160 protrudes from the surface of the first connection pipe section 110 and/or the second connection pipe section 130 by a second predetermined height, so that even if the first connection pipe section 110 and/or the second connection pipe section 130 rubs with the cartridge assembly or the box, the protruding abrasion-resistant rib 160 is preferentially worn without damaging the first connection pipe section 110 and/or the second connection pipe section 130, thereby prolonging the service life of the water intake pipe 100. By way of example, the present utility model defines the second predetermined height to be a value greater than the first connecting tube segment 110 and/or the second connecting tube segment 130 tube wall thickness to further increase the wear resistance of the first connecting tube segment 110 and/or the second connecting tube segment 130.

In some embodiments, vibration of the laundry treating apparatus during operation may also reduce the strength of the connection between the first connection pipe section 110 and the second connection pipe section 130 of the water inlet pipe 100, and thus, the present utility model provides the abrasion-resistant rib 160 at the connection between the first connection pipe section 110 and the second connection pipe section 130, and further enhances the strength of the connection between the first connection pipe section 110 and the second connection pipe section 130 on the basis of increasing the abrasion resistance of the first connection pipe section 110 and/or the second connection pipe section 130.

In some embodiments, the wear-resistant rib 160 includes a plurality of cross-linked transverse ribs 161 and longitudinal ribs 162 to further strengthen the strength of the wear-resistant rib 160. It should be noted that the number of transverse ribs 161 and longitudinal ribs 162 may be set according to the specific circumstances of the first connecting pipe segment 110 and the second connecting pipe segment 130. As an example, as shown in fig. 3, in the exemplary embodiment of the present utility model, two lateral ribs 161 are provided, four longitudinal ribs 162 are provided, and both ends of the four longitudinal ribs 162 are respectively connected to the two lateral ribs 161, thus forming a plurality of "mouth" shaped structures.

In some embodiments, the special structure of the corrugated pipe section 120 easily causes the corrugated pipe section 120 to bend during the installation process, so that the water inlet end and the water outlet end of the water inlet pipe 100 cannot be connected with the water inlet assembly 200 and the barrel assembly according to the preset positions, and thus the structures of the avoidance groove 150, the wear-resistant rib 160 and the like provided by the utility model are misplaced, and cannot play a corresponding role. Based on this, as shown in fig. 3, the present utility model is provided with a first positioning structure 170 for positioning connection with the water intake assembly 200 at the one end of the bellows section 120, and a second positioning structure 180 for positioning connection with the cartridge assembly at the one end of the first connection tube section 110. Therefore, the problem that the corrugated pipe section 120 is easy to bend and cannot be positioned or is positioned inaccurately can be solved, and the positions of structures such as the avoidance groove 150 and the wear-resisting rib 160 are matched with the positions of other surrounding parts. Moreover, the installation of the water inlet pipe 100 by the installer can be facilitated by providing the first and second positioning structures 170 and 180, and the working efficiency can be improved.

In some embodiments, as shown in fig. 1, the first positioning structure 170 includes a first positioning portion 171 and a second positioning portion 172. The first positioning portion 171 and the second positioning portion 172 are two-sheet structures disposed at the water inlet end of the bellows section 120, and a predetermined interval distance is provided between the first positioning portion 171 and the second positioning portion 172 to form a first positioning groove 173. It will be appreciated that the water inlet assembly 200 is further provided with a positioning protrusion 210 capable of matching with the first positioning groove 173, as shown in fig. 5 and 6. When the water inlet pipeline 100 is connected with the water inlet assembly 200, the water inlet end of the corrugated pipe section 120 is sleeved outside the water outlet end of the water inlet assembly 200, and the positioning protrusion 210 is embedded into the first positioning groove 173, so that the water inlet assembly 200 is in positioning connection with the water inlet pipeline 100.

In some embodiments, as shown in fig. 1, the second positioning structure 180 includes at least two positioning portions 181, and a predetermined spacing distance is provided between adjacent positioning portions 181 to form a second positioning groove 182. It will be appreciated that a detent projection (not shown) is also provided on the cartridge assembly that mates with the second detent 182 described above. When the water inlet pipe 100 is connected with the barrel assembly, the water outlet end of the first connecting pipe section 110 is sleeved outside the water inlet end of the barrel assembly, and the positioning protrusion is embedded into the second positioning groove 182, so that the water inlet pipe 100 is in positioning connection with the barrel assembly.

It should be noted that, the water inlet pipe 100 of the present utility model is made of rubber, and the structure included in the water inlet pipe 100 is manufactured by an integral molding process.

The exemplary embodiment of the present utility model also provides a laundry treating apparatus including the water inlet pipe 100, the water inlet assembly 200, and the cartridge assembly described above; the water inlet end of the water inlet pipe 100 is connected with the water inlet assembly 200, and the water outlet end of the water inlet pipe 100 is connected with the cylinder assembly.

It should be noted that the above description of the features and effects of the water inlet assembly 200 may be entirely applied to the laundry treating apparatus of this time, and the present utility model will not be repeated here.

The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the utility model, may be made by those skilled in the art without departing from the scope of the utility model.
