[0015] [First embodiment] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Figure 1 1 is a perspective view of a washing cover 10 according to an embodiment of the present disclosure. Figure 2 It is a top view showing a state where the washing cover 10 is attached to the washing tank. Figure 3 It is a partial cross-sectional view showing a state where the washing cover 10 is mounted on the washing tank.

[0016] Washing cover 10 can be used for both vertical washing machines and drum-type washing machines, but in the following description, the vertical direction is defined assuming a use state of a vertical washing machine (a state of being mounted on a vertical washing machine).

[0017] In addition, in the present invention, "washing machine" refers to all equipment that performs various treatments such as washing on laundry. The laundry treatments of the washing machine include washing, drying, deodorization, sterilization, etc. The laundry is not particularly limited. As the laundry, for example, cloth products can be cited. Specific examples of the laundry include clothing such as clothes, hats, gloves, etc., shoes, bags, handkerchiefs, towels, etc., bedding such as curtains, blankets, towel covers, and quilt covers, carpets, stuffed dolls, etc. like Figure 1 As shown, the washing cover 10 is in the shape of a bottomed cylinder, and has a bottom portion 11 and a side portion 12. The side portion 12 is a portion opposite to the inner peripheral surface of the washing tank. The side portion 12 may be, for example, a cylindrical shape having an outer diameter slightly smaller than the inner diameter of the inner peripheral surface of the washing tank, or may be in partial or entire contact with the inner peripheral surface of the washing tank. The side portion 12 is connected to the bottom portion 11. The bottom portion 11 is supported by the side portion 12. In the present embodiment, the side portion 12 is set in a circular ring shape.

[0018] The bottom portion 11 is a portion that is pressed to prevent the laundry from flying out of the washing tub. The bottom portion 11 of the present embodiment may also have a plurality of beams 111 extending radially from the center along the circumferential direction. In addition, the beams 111 may also be in the shape of blades inclined in the same direction along the circumferential direction. For example, in the case where the washing machine has a drying function and a structure in which warm air is blown into the washing tub from above, if the beams 111 are in the above-mentioned blade shape, the washing cover 10 rotates synchronously with the rotation of the washing tub during the drying process, and the airflow generated by the rotation can be used to introduce warm air into the washing tub.

[0019] When the washing cover 10 is installed on the washing tank, the side portion 12 contacts the inner circumferential surface of the washing tank. The side portion 12 has at least one engaging claw 121. Specifically, in the present embodiment, the side portion 12 has a plurality of engaging claws 121. The plurality of engaging claws 121 are arranged at equal intervals with intervals from each other in the circumferential direction. The number of engaging claws 121 of the side portion 12 is not particularly limited, and may be one, two, or four or more, but preferably three. This is because, in the case where three engaging claws 121 are provided, if the user operates two engaging claws 121 with both hands, the washing cover 10 can be easily removed by removing the remaining engaging claw 121.

[0020] The engaging claw 121 can engage with the engaged portion formed on the inner circumference of the washing tank. The washing cover 10 is fixed to the washing tank by engaging at least one engaging claw 121 with the engaged portion formed on the inner circumference of the washing tank. The engaged portion can be composed of, for example, a step or a concave-convex portion such as a concave portion or a convex portion. In this embodiment, an example in which the engaged portion is composed of a step 21 is described.

[0021] The engaging claw 121 has a protrusion 1212 that can be engaged with the engaged portion and a force-applying portion that applies force to the protrusion 112 toward the inner peripheral surface of the washing tank. In this embodiment, an example in which the force-applying portion is composed of a leaf spring 1211 is described. However, in this disclosure, the force-applying portion is not particularly limited as long as it is a component that can apply force to the protrusion.

[0022] In the side portion 12, the engaging claw 121 is provided at least at one place, but in order to stably fix the washing cover 10, it is preferred that the engaging claw 121 is provided at a plurality of places along the circumferential direction of the side portion 12 ( Figure 1 In addition, when the engaging claws 121 are provided at a plurality of locations, they are preferably arranged at equal angular intervals along the circumferential direction.

[0023] like Figure 2 and Figure 3 As shown, in this embodiment, the washing cover 10 is installed on the balancer 20 which is a part of the washing tank. Due to the manufacturing process, the balancer 20 has a step 21 that can engage the engaging claw 121, so it is preferably used as the installation position of the washing cover 10. In addition, since the balancer 20 is arranged on the upper part of the washing tank, by installing the washing cover 10 on the balancer 20, the storage space of the washing objects below the washing cover 10 can be fully ensured. However, if there is a step on the inner circumferential surface of the washing tank that can engage the engaging claw 121, the washing cover 10 can be installed at any position, and the installation position of the washing cover 10 is not limited to the balancer 20.

[0024] The washing cover 10 can be easily installed on the washing tank (here, the balancer 20) by covering the washing tank with the washing cover 10 from above and pressing the engaging claw 121 (more specifically, the protrusion 1212) to a position engaged with the engaged portion (here, the step 21) in the washing tank. By fixing the washing cover 10 to the washing tank in this way, the washing cover 10 can be prevented from moving or rubbing relative to the washing tank due to the washing water flow and pulsation. As a result, it is possible to prevent the washing cover 10 from falling off the washing tank during washing or the washing cover 10 from being worn due to friction with the washing tank.

[0025] [Second Embodiment] When the washing cover 10 is removed from the washing tank, the front end of the engaging claw 121 is pulled toward the inner peripheral side, and the washing cover 10 is lifted upward in a state where the engagement with the step 21 is released. The engaging claw 121 may also have a structure that can more easily perform loading and unloading, that is, the action of engaging or releasing the engaging state. Figure 4 It is a perspective view of the washing cover 10A in this embodiment. Figure 5 It is a partial cross-sectional view showing a state where the washing cover 10A is mounted on the washing tank.

[0026] like Figure 4 and Figure 5 As shown, the washing cap 10A of the present embodiment is configured by replacing the engaging claw 121 in the first embodiment with an engaging claw 121A. In addition, in the present embodiment, a configuration is exemplified in which the engaging claw 121A is formed at three locations.

[0027] The engaging claw 121A has a protrusion extending radially inward from the leaf spring 1211 constituting the plate-shaped portion when viewed from above. The protrusion may be, for example, plate-shaped. In the present embodiment, the protrusion constitutes the operating portion 1213. The operating portion 1213 is provided near the front end (lower end side) of the engaging claw 121A so as to protrude toward the inner circumference of the washing cover 10A. The engaging claw 121A is, for example, formed into a plate shape in which the thickness direction is consistent with the up-down direction, and is in a shape that is easily stretched by the user by pinching it. When removing the washing cover 10A from the washing tank, the user pinches the operating portion 1213 toward the inner circumference of the washing cover 10A. Figure 5 The engagement claw 121 can be easily released by pulling in the direction of arrow A in FIG.

[0028] In addition, even if the formation position of the engaging claw 121A is set to three positions, the washing cover 10A is easy to remove from the washing tank. Figure 1 and Figure 2 When the locking claws 121 are arranged at four positions as in the washing cover 10 shown in the figure, it is easy for the user to use both hands to align the two locking claws 121 located at opposite positions (for example, Figure 2However, in this case, the remaining two engaging claws 121 (for example, Figure 2 The engaging claws 121 disposed on both sides in the up-down direction are also located at opposite positions, so even if the washing cover 10 is lifted up, it is difficult to remove it from the washing tank.

[0029] On the other hand, in the washing cover 10A having the engaging claws 121A provided at three locations, when two engaging claws 121A are disengaged, the remaining engaging claws 121A that are not disengaged become one, so the washing cover 10A can be easily lifted up and removed from the washing tub.

[0030] [Third Embodiment] Figure 6 1 is a perspective view of an engagement claw 121B as another modified example of the engagement claw 121. In the engagement claw 121B, an opening 1214 and a rib 1215 are provided in the operating portion 1213. The opening 1214 is formed so as to penetrate the main surface of the operating portion 1213 in the up-down direction. The rib 1215 is formed so as to protrude upward from the front end (inner peripheral side) of the operating portion 1213.

[0031] When removing the washing cover 10 having the engaging claw 121B from the washing tank, the user can hook the fingertips on the opening 1214 or the rib 1215 and pull the operating portion 1213. This makes it easy to release the engaging claw 121B, and the operation of removing the washing cover 10 from the washing tank becomes easy. Figure 6 In the example of the engaging claw 121B in FIG. 1 , both the opening 1214 and the rib 1215 are provided in the operating portion 1213 , but a structure in which only one of them is provided may be adopted.

[0032] [Fourth Embodiment] Figure 7 It is a perspective view of an engaging claw 121C which is still another modified example of the engaging claw 121 . Figure 8 1 is a partial cross-sectional view showing the installation state of the washing cover 10 having the engaging claw 121C installed on the washing tank. In the engaging claw 121C, the shape of the operating portion 1213 is different from that of the second and third embodiments. Specifically, the operating portion 1213 in the engaging claw 121C is arranged to protrude toward the inner peripheral side of the washing cover 10A near the lower end of the engaging claw 121C and then further extend toward the upper side.

[0033] When removing the washing cover 10 having the engaging claw 121C from the washing tank, the user can hook the fingertips on the front end (upper end side) of the operating portion 1213 and pull the operating portion 1213 in the direction of arrow B to release the engagement. Alternatively, the engagement can also be released by pressing the front end (upper end side) of the operating portion 1213 in the direction of arrow C. Therefore, the user can release the engagement of the engaging claw 121C by an operation method that is easy for the user to perform.

[0034] In addition, if Fig. 9 As shown in the figure, the operating portion 1213 of the engaging claw 121C may also have a curve that bends near the lower end of the engaging claw 121C. In addition, a rib 1216 that protrudes toward the inner peripheral side of the washing cover 10 may also be provided at the front end (upper end side) of the operating portion 1213. When the front end of the operating portion 1213 is provided with the rib 1216, when the operating portion 1213 is pressed in the direction of the arrow C, the fingertips are hooked on the rib 1216, thereby making it easy to apply force.

[0035] The embodiments disclosed this time are illustrative in all aspects and are not to be interpreted in a limiting sense. Therefore, the technical scope of the present disclosure is not to be interpreted solely by the above-mentioned embodiments but is to be determined based on the description of the claims.
