Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a suction port attachment part for a jet bath (a bathtub with a bubble ejection function), and more particularly to a suction port attachment part for a jet bath that is used by being attached to a suction port for circulating hot water in a bathtub.
[0002]
[Prior art]
Conventionally, as this type of attachment parts, for example, a filter that has a filter function for capturing hair loss, etc., that has a mesh-like side facing the inside of the bathtub, or a filter in which many pins for entwining hair loss, etc. are implanted. There is known a member provided with a member so that it can be attached to the inlet of circulating hot water in a bathtub (see, for example, JP-A-9-173232 and JP-A-6-336752).
[0003]
[Problems to be solved by the invention]
By the way, this kind of parts can remove hair loss etc. from circulating hot water and prevent hair loss etc. from adversely affecting the circulation pump, and the suction force of the pump is dispersed so that the bather can inhale the hair with a strong force. This type of bathtub can be said to be a necessity because it can prevent drowning accidents. However, for reasons such as the complexity of cleaning, bathers have conventionally taken a bath with this type of component removed from the inlet.
[0004]
Therefore, in this type of bathtub, there has been a risk that the smooth operation of the pump is hindered due to hair loss in the circulating hot water, etc., or that the bather sucks hair into the suction port and drowns.
[0005]
The present invention has been proposed in view of such a conventional situation.
[0006]
Therefore, the technical problem of the present invention is that even if the cover with a filter function is mischievously rotated, the cover cannot be removed, and circulating hot water is prevented from flowing around the back side of the cover and flowing into the suction port. Therefore, it is intended to provide a suction port attachment part for a jet bath formed so as to prevent hair loss and the like from adversely affecting the pump and to prevent an accident that a bather's hair is strongly sucked into the suction port and drowns.
[0007]
[Means for Solving the Problems]
