The sweep-out slope 65 is a gentle upward transition mode toward the sweep-out port 63 from the inner peripheral surface of the outer wall portion 62, and the slope gradually rises to almost the same height as the portion of the outer wall portion 62 adjacent to the sweep-out port 63. It has a surface shape. Further, the sweep-out slope portion 65 is configured to lead to the outside of the hair catcher 6 at the sweep-out port 63.

It should be noted that a slight protrusion (low weir portion) may be provided at a portion of the sweep-out slope portion 65 corresponding to the sweep-out port 63. In this case, it is possible to prevent foreign matter from easily flowing out from the sweep-out port 63 by drainage or the like.

Further, in terms of improving cleanability (easiness of sweeping out foreign matter), it is preferable to have a shape in which the sweeping slope portion 65 is displaced more gently. Therefore, in the present embodiment, in order to more reliably improve the cleanability, the starting point of the displacement (the starting point of the inclination) in the sweep-out slope 65, and in the present embodiment, the end edge located on the opposite side to the sweep-out port 63. ) Is provided at a position substantially overlapping with the center of the hair catcher 6 when viewed in a plan view. The position of the starting point of the displacement can be changed as appropriate. For example, the starting point of the displacement may be provided on the center side of the hair catcher 6 rather than the central portion of the center of the hair catcher 6 and the sweep-out port 63. , May be provided at a position beyond the center of the hair catcher 6 on the side opposite to the sweep-out port 63.

Further, the insertion portion 67 is formed through the sweep-out slope portion 65 at a predetermined position on the sweep-out port 63 side that is off the center of the hair catcher 6 when viewed in a plan view. The insertion portion 67 is a portion through which the support shaft 52 is inserted, and has a shape that opens to the outer edge of the hair catcher 6 located on the sweep-out port 63 side. Further, the insertion portion 67 has a shape in which the width gradually increases toward its own opening located on the outer edge side of the hair catcher 6.

The horizontal bottom portion 66 is a portion of the sweep-out slope portion 65 that is continuous with the edge opposite to the sweep-out port 63 and extends substantially in the horizontal direction. In the present embodiment, the portion of the bottom wall portion 61 other than the sweep-out slope portion 65 is the horizontal bottom portion 66, and the horizontal bottom portion 66 constitutes the bottommost portion of the bottom wall portion 61. The term "almost horizontal direction" means not only a strict horizontal direction but also a direction slightly inclined with respect to the horizontal direction. Further, the bottom wall portion 61 may be provided with an inclined portion that is inclined in the opposite direction to the sweeping slope portion 65 at a portion of the bottom wall portion 61 that is opposite to the sweep-out slope portion 65 with the horizontal bottom portion 66 interposed therebetween.

The handle portion 64 is a portion provided on the assumption that the user holds the knob. The handle portion 64 is provided on the outer edge portion of the hair catcher 6 located on the opposite side of the sweep-out port 63, and has a shape that protrudes upward and outward.

In addition, among the portions of the bottom wall portion 61 that form the hole portion 61A, the portions that extend in the direction intersecting the inclination direction of the sweep-out slope portion 65 when viewed in a plan view, and are on the sweep-out port 63 side along the sweep-out slope portion 65. A resistance reducing portion 68 is provided at a portion (referred to as a “movement obstructing portion”) facing in the direction opposite to the moving direction of the foreign matter to. That is, among the portions of the bottom wall portion 61 that form the hole portion 61A, the resistance reducing portion 68 is provided in the portion that is particularly likely to come into contact with the foreign matter when moving the foreign matter to the sweep-out port 63 side along the sweep-out slope portion 65. It is provided. The resistance reducing portion 68 is a portion that gradually rises toward the sweep-out port 63 side and forms a continuous inclined surface shape or curved surface shape (in the present embodiment, an inclined surface shape) on the upper surface of the bottom wall portion 61. In the present embodiment, there are a plurality of the movement-inhibiting portions, and a resistance reducing portion 68 is provided for each of the movement-inhibiting portions, but the resistance-reducing portion is provided for at least a part of the plurality of movement-inhibiting portions. 68 may be provided.

As described in detail above, according to the present embodiment, the hair catcher 6 is provided with a sweep-out slope portion 65. Therefore, by moving the foreign matter collected on the bottom wall portion 61 to the sweep-out port 63 side along the sweep-out slope portion 65 by a finger or a cleaning tool, the foreign matter is moved from the sweep-out port 63 to the outside of the hair catcher 6. It is possible to sweep out foreign matter and remove foreign matter. Therefore, when removing the foreign matter, it is not necessary to lift the foreign matter so as to exceed the outer wall portion 62, and excellent cleaning performance can be realized.

Further, the outer wall portion 62 and the sweep-out slope portion 65 can prevent the collected foreign matter from easily flowing out. Therefore, the function of the hair catcher 6 of collecting foreign substances can be effectively exerted.

In addition, due to the presence of the sweep-out slope portion 65, foreign matter is concentratedly accumulated in the portion of the bottom wall portion 61 opposite to the sweep-out port (in this embodiment, the horizontal bottom portion 66). Therefore, the foreign matter can be removed more easily, and the cleanability can be further improved. Further, the concentrated accumulation of foreign matter in the portion of the bottom wall portion 61 opposite to the sweep-out port 63 effectively suppresses a situation in which the hole portion 61A is blocked by the foreign matter in a wide range of the bottom wall portion 61. This makes it possible to prevent excessive deterioration of drainage performance over a long period of time.

Further, since the hair catcher 6 has a characteristic shape in which the sweep-out slope portion 65 is present, the user can intuitively grasp the cleaning method of the hair catcher 6. This makes it possible to improve usability.

In addition, by providing the horizontal bottom portion 66 on the bottom wall portion 61, the height of the hair catcher 6 can be suppressed while giving the sweep-out slope portion 65 a certain degree of gradient. As a result, it is possible to easily secure the installation space of the hair catcher 6 while preventing the outflow of foreign matter from the sweep-out port 63 and increasing the collection capacity of the foreign matter.

Further, the width W1 of the sweep-out port 63 is set to be 1/3 or more of the maximum width W2 of the bottom wall portion 61, and the sweep-out port 63 is sufficiently wide. Therefore, it is possible to very easily sweep out the foreign matter from the sweep-out port 63 to the outside of the hair catcher 6, and the cleanability can be further improved.

Further, a resistance reducing portion 68 is provided corresponding to a portion (movement inhibiting portion) that can inhibit the movement of foreign matter in the bottom wall portion 61. As a result, the foreign matter can be removed more easily, and the cleanability can be further improved.

Further, since the handle portion 64 is provided on the side opposite to the sweep-out port 63, when the handle portion 64 is held when removing foreign matter, a force applied to the hair catcher 6 when removing the foreign matter is applied. Can be received more reliably. As a result, the hair catcher 6 can be held more reliably when the foreign matter is removed, and the cleanability can be further improved.

In addition, the insertion portion 67 is open to the outer edge of the hair catcher 6 located on the sweep-out port 63 side. Therefore, it is possible to prevent foreign matter from being caught on the portion of the sweep-out slope portion 65 that forms the inserted portion 67. Thereby, the foreign matter can be removed more easily. In particular, in the present embodiment, since the inserted portion 67 has a shape that gradually widens toward its own opening side, it is possible to extremely effectively suppress the catching of foreign matter. Further, since the inserted portion 67 is open to the outer edge of the hair catcher 6, it is possible to easily clean the portion of the bottom wall portion 61 that forms the inserted portion 67.

Further, by moving the hair catcher 6 in a direction intersecting the axial direction of the support shaft 52, the support shaft 52 can be pulled out from the insertion portion 67 and the hair catcher 6 can be removed. As a result, the hair catcher 6 can be easily cleaned independently, and the cleanability can be further improved.

In addition, since the insertion portion 67 is provided on the side of the sweep-out port 63 off the center of the hair catcher 6, the hair catcher 6 can be removed without moving the hair catcher 6 so much. As a result, the convenience for the user can be enhanced, and good usability can be realized.

At the same time, in a state where the support shaft 52 is inserted through the insertion portion 67 (that is, during use), the support shaft 52 hinders the outflow of foreign matter from the sweep-out port 63. As a result, foreign matter can be collected more reliably.

That is, the bottom wall portion 61 may be provided with a continuous protrusion 69 extending along substantially the same direction as the movement direction (the foreign matter sweeping direction) toward the foreign matter sweeping port 63 side when the foreign matter is removed. In this case, a foreign substance (for example, hair) can be placed on the continuous protrusion 69 and moved to the sweep-out port 63 side in a state of being floated from the bottom wall portion 61. Further, since the foreign matter floats from the bottom wall portion 61 by the continuous protrusion 69, it becomes possible to easily remove the foreign matter by sieving it off. As a result, foreign matter can be removed more easily, and better cleaning performance can be realized.

The number of continuous protrusions 69 is not particularly limited, and may be one or a plurality of continuous protrusions 69.
