Abstract

The present disclosure provides a thermally insulated non-inflatable pool, including: a liner, having a water storage cavity; a frame, surrounding a perimeter of the liner; a connection member, fixing the liner to the frame; and a thermal insulation structure, at least a part of which is arranged between the liner and the frame. At least a part of the thermal insulation structure is attached to an outer surface of the liner; and/or, at least a part of the thermal insulation structure is attached to an inner surface of the frame. The present disclosure may reduce heat loss in the water storage cavity of the thermally insulated non-inflatable pool and prolong heat preservation time for water in the water storage cavity.

First claim

What is claimed is:

1 . A thermally insulated non-inflatable pool, comprising:
a liner, having a water storage cavity; a frame, surrounding a perimeter of the liner; a connection member, fixing the liner to the frame; and a thermal insulation structure, at least a part of which is arranged between the liner and the frame, wherein at least a part of the thermal insulation structure is attached to one or more of:
an outer surface of the liner; and
inner surface of the frame.

2 . The thermally insulated non-inflatable pool of claim 1 , wherein the thermal insulation structure comprises a cylinder defined by a wall and presenting an upper end and a lower end, an inner side surface of the cylinder approximating the outer surface of the liner, and an outer side surface of the cylinder approximating the inner surface of the frame.

3 . The thermally insulated non-inflatable pool of claim 2 , wherein the upper end and the lower end of the cylinder are provided with openings.

4 . The thermally insulated non-inflatable pool of claim 2 , wherein the inner side surface of the cylinder is adhered to the outer surface of the liner, and/or the outer side surface of the cylinder is adhered to the inner surface of the frame.

5 . The thermally insulated non-inflatable pool of claim 2 , wherein the wall of the cylinder presents a wall thickness that gradually increases with a preconfigured thickness gradient from the upper end to the lower end in a depth direction of the thermally insulated non-inflatable pool.

6 . The thermally insulated non-inflatable pool of claim 5 , wherein the thickness gradient is preconfigured so that when the water storage cavity is filled with water, and the liner is compressed by the water, the water storage cavity assumes a relatively uniform inner diameter.

7 . The thermally insulated non-inflatable pool of claim 5 , wherein the thickness gradient increases in one or more of a linear, exponential, or stepwise manner.

8 . The thermally insulated non-inflatable pool of claim 1 , wherein:
the thermal insulation structure comprises a plurality of thermal insulation units arranged between the liner and the frame, the thermal insulation units being arranged in one or more of the following configurations: the plurality of thermal insulation units are spliced to each other; the plurality of thermal insulation units are arranged at intervals; the plurality of thermal insulation units are arranged in a plurality of overlapping layers; and some of the plurality of thermal insulation units are spliced to each other and other thermal insulation units are arranged at intervals.

9 . The thermally insulated non-inflatable pool of claim 2 , wherein the thermal insulation structure further comprises a bottom sheet arranged under a bottom wall of the liner.

10 . The thermally insulated non-inflatable pool of claim 9 , wherein the bottom sheet is adhered to the lower surface of the bottom wall of the liner.

11 . The thermally insulated non-inflatable pool of claim 2 , wherein a material of the thermal insulation structure comprises one or more of pearl cotton, expandable expanded polyethylene (EPE), expanded polystyrene (EPS), fiberglass batting, elastomeric foam, polyurethane (PU) foam, sponge, and silk wadding.

12 . The thermally insulated non-inflatable pool of claim 1 , wherein:
a top region of the frame is provided with a first extension portion extending outward with respect to the water storage cavity, and the first extension portion is provided with a first protrusion; a top region of the liner is provided with a second extension portion extending outward with respect to the water storage cavity, and the second extension portion is coupled to the first extension portion and covers the first protrusion to form a second protrusion; and the connection member clamps the second protrusion together with the first protrusion.

13 . The thermally insulated non-inflatable pool of claim 1 , wherein a material of the liner comprises one or more of flexible polyvinyl chloride (PVC), polyurethane (PU), a PVC mesh material, and a PU mesh material.

14 . The thermally insulated non-inflatable pool of claim 1 , wherein the frame is constructed from one or more of: a structurally supportive plastic, polyethylene (PE), polypropylene (PP), and polystyrene (PS).
