Abstract

A drainage device for an above-ground pool, and an above-ground pool including the drainage device are provided. The drainage device includes a drainage pipe, with inlet and outlet ends, and a drainage valve connected to the inlet end of the drainage pipe. The drainage valve includes a water inlet periphery, defining a water inlet in fluid communication with the inlet end of the drainage pipe, and a connecting member disposed circumferentially around the water inlet periphery. The connecting member is radially spaced apart from the water inlet periphery. The connecting member may be formed by injection molding around the water inlet periphery.

First claim

What is claimed is:

1. An above-ground pool, comprising:
a pool bottom;
a pool wall surrounding the pool bottom, the pool wall and the pool bottom together defining a water cavity; and
a drainage device installed at the pool bottom, the drainage device comprising:
a flexible drainage pipe having an inlet end and an outlet end; and
a reinforcing member disposed within the drainage pipe and extending in a lengthwise direction along a length of the drainage pipe.

2. The above-ground pool according to claim 1 , wherein the reinforcing member comprises a rib integrally formed with the inner wall of the drainage pipe, the rib protruding radially inward from the inner wall of the drainage pipe.

3. The above-ground pool according to claim 2 , wherein the reinforcing member comprises a plurality of evenly-spaced ribs protruding inward from the inner wall of the drainage pipe.

4. The above-ground pool according to claim 1 , wherein the reinforcing member comprises a supporting pipe embedded in the inner wall of the drainage pipe, wherein a hardness of the supporting pipe is greater than a hardness of the drainage pipe.

5. The above-ground pool according to claim 1 , wherein the drainage device further comprises:
a drainage valve, connected to the inlet end of the drainage pipe, the drainage valve comprising:
a water inlet periphery defining a water inlet in fluid communication with the inlet end of the drainage pipe, and
a connecting member disposed circumferentially around the water inlet periphery and radially spaced apart from the water inlet periphery.

6. The above-ground pool according to claim 5 , wherein the connecting member is formed by injection molding around the water inlet periphery.

7. The above-ground pool according to claim 1 , wherein the drainage device further comprises:
a drainage pipe connector having an inlet end configured to be connected to the outlet end of the drainage pipe and an outlet end opposite the inlet end.

8. The above-ground pool according to claim 1 , wherein the drainage device further comprises:
a drainage pipe holder connected to the inlet end of the drainage pipe, the drainage pipe holder formed of a material having a hardness greater than a hardness of the drainage pipe; and
the drainage pipe holder comprising:
a base configured to accommodate therein the water inlet, and
a plug plate fixing the water inlet to the base.

9. The above-ground pool according to claim 8 ,
wherein the plug plate extends in a direction substantially parallel to a length of the drainage pipe and is fitted to the base in an insertion direction substantially parallel to the length of the drainage pipe, and
wherein one of the plug plate and the base comprises an insertion groove extending in the insertion direction, and another of the plug plate and the base comprises a protruding strip extending in the insertion direction.

10. The above-ground pool according to claim 8 ,
wherein the plug plate extends in a direction substantially perpendicular to a length of the drainage pipe and is fitted to the base in an insertion direction substantially perpendicular to the length of the drainage pipe, and
wherein one of the plug plate and the base comprises a snap groove extending in the insertion direction, and another of the plug plate and the base comprises a snap fastener extending in the insertion direction.
