JP 2001-212534 A

  However, in the conventional cleaning bowl, since the mesh body is fixed to the frame body by adhesion or welding, the mesh body cannot be removed from the frame body and replaced, and only the mesh body is damaged or deformed. Even then, the entire cleaning tub must be replaced with a new one. In other words, the mesh body is often lower in strength than the frame body, and the mesh body is more likely to deteriorate earlier, and when the mesh body is damaged, the frame body itself can still be used. In other words, the entire cleaning bowl must be discarded, and environmental resources cannot be effectively used. In addition, a cleaning rod in which the mesh body is bonded to the frame body may cause the adhesive to elute into the cleaning liquid when, for example, a highly acidic cleaning liquid is used when cleaning special parts. There is also a disadvantage that proper cleaning cannot be performed.

  The present invention has been devised by paying attention to the above inconveniences, and an object of the present invention is to provide a cleaning rod in which a net-like body stretched in a window hole is detachable.

(1) In order to achieve the above object, the present invention includes a cylindrical body portion in which an object to be cleaned is accommodated,
The body includes a hollow outer member in which an outer window hole is formed, and an inner member in which an inner window hole is formed to be detachably attached to the inner side of the outer member. And a net-like body stretched between the window holes in a state of being sandwiched between the outer member and the inner member.

(2) Further, the present invention includes a cylindrical body portion in which an object to be cleaned is accommodated, and a bottom portion in which a window hole is formed while being detachably attached to the lower side of the body portion,
The trunk portion is configured to include a net-like body stretched on the window hole while being sandwiched between the bottom portions.

(3) Here, the trunk portion further includes a hollow outer member and an inner member that is detachably attached to the inner side of the outer member.
It is preferable that the mesh body is configured to be sandwiched between the outer member, the inner member, and the bottom.

(4) Furthermore, it further comprises a fixing means for fixing the mesh body to the inner member,
Preferably, the fixing means is configured to be detachable from the inner member with the inner member removed from the outer member.

  In the claims and the specification, “upper” and “lower” mean “upper” and “lower” in the cleaning bowl in the posture of FIG. 1 unless otherwise specified.

  According to the configuration of (1), since the mesh body is sandwiched between the outer member and the inner member, the mesh member can be removed by removing the inner member from the outer member. In other words, the mesh body can be stretched over the window hole without using adhesion or welding, and when the inner member is removed from the outer member, the mesh body becomes detachable with respect to the body portion. Thereby, when a mesh body is damaged, deformed, etc., it can be replaced with a new mesh body without difficulty, and it is not necessary to discard the entire cleaning basket, thereby making it possible to effectively use environmental resources. In addition, since the mesh body is not stretched in the window hole using adhesion etc., the manufacturing work of the product can be easily performed, and any cleaning liquid can be used to prevent impurities such as adhesive from eluting into the cleaning liquid. Cleaning can be performed appropriately.

  According to the configuration of (2), since the mesh body is sandwiched between the trunk portion and the bottom portion, the mesh body can be removed by removing the bottom portion from the trunk portion, and (1) The same effect as that of the configuration can be obtained.

  According to the configuration (3), it is possible to more firmly support the net-like body stretched on the bottom where the weight of the object to be cleaned is applied, and to further prevent the net-like body from being unexpectedly detached from the cleaning basket.

  According to the configuration of (4), in the state where the inner member is attached to the outer member, the mesh body can be supported more firmly by the fixing means, while in the state where the inner member is removed from the outer member, the fixing means Can be removed, and the mesh body can be easily replaced.
