This application claims priority from Chinese patent Application CN202021816743.3 filed Aug. 27, 2020 in China, the disclosure of which is incorporated herein by reference in its entirety.
Apparatuses and methods consistent with exemplary embodiments relate to above-ground pools, and more specifically, to a thermal-insulation cover for an above-ground pool, and an above-ground pool comprising the thermal-insulation cover.
Above-ground pools (such as an inflatable pools) are popular with consumers because they are easy to carry and install and are effective to use. Since an above-ground pool is usually used in an outdoor environment, pool pumps for such above-ground pools typically include a heater so that the pool water can be heated to a temperature suitable for a swimmer, particularly when the temperature is low outside. Additionally, certain above-ground pools include a thermal insulation lid and lid liner that cover the top of the pool body and are usually made of polyvinyl chloride (PVC). An above-ground pool may also include a thermal insulation ground mat, disposed under the pool, to increase the thermal insulation.
Unfortunately, such thermal insulation lids, lid liners, and ground mats have no specific insulation structure or insulation material, often resulting in poor thermal insulation, easy dissipation of heat, and high heating energy consumption. In particular, when a swimmer enters a pool, the thermal insulation lid and lid liner must be removed, necessarily reducing the insulation of the pool, and increasing heat loss and energy consumption.
Example embodiments may address at least the above problems and/or disadvantages and other disadvantages not described above. Also, example embodiments are not required to overcome the disadvantages described above, and may not overcome any of the problems described above.
One or more example embodiments may provide a new thermal-insulation cover for an above-ground pool, which thermal-insulation cover may improve the insulation effect of the above-ground pool and also provide energy conservation.

As shown in
The pool body 1 includes a pool bottom 14 and an inflatable pool wall coupled to the pool bottom 14. The pool bottom 14 may be formed of a PVC sheet material. If an insulation effect of the pool bottom 14 needs to be increased, the bottom 14 may be designed as a dual layer structure, including one or more insulation materials disposed between the two sheets. For example, one or more insulation materials such as foam, aluminum foil, sponge, and silk wadding may be disposed between two PVC sheets of the bottom 14. The inflatable pool wall includes, for example, an inner wall 11, formed of the PVC sheet material, an outer wall 12, and a plurality of tension bands 13, as shown in
The pool pump 5 may include a filter pump, used to filter impurities from the water, and a gas pump used to inject gas into the water in a water injection chamber, in order to provide a wave function and a massage function. The filter pump provides water circulation by means of a water inlet pipeline and a water outlet pipeline, which are connected to the filter pump and which pass through the inflatable pool wall, and by means of the water injection chamber. The gas pump supplies gas to the water injection chamber by means of a gas inlet pipeline, which is connected to the gas pump and which also passes through the inflatable pool wall.
According to an example embodiment, the thermal-insulation structure of the inflatable pool comprises a thermal-insulation cover 2. As shown in
The thermal-insulation portion may include, for example, an inner layer 21 formed of the PVC sheet material, an outer layer 22, and an intermediate layer 23 made of a thermal-insulation material and arranged between the inner layer 21 and the outer layer 22. The top of the inner layer 21 is connected to the top of the outer layer 22, and the bottom of the inner layer 21 is connected to the bottom of the outer layer 22, so as to define an enclosed chamber between the inner layer 21 and the outer layer 22, the enclosed chamber being suitable to be filled with the intermediate layer 23. The intermediate layer 23 may be made of any kind of collapsible thermal-insulation material or materials, such as any one or more of foam, aluminum foil, sponge, silk wadding, and any other material as would be understood by one of skill in the art. The extended portion comprises an upper part 24 and a lower part 25 which are made of the PVC sheet material. The upper part 24 is annular, and is connected to the top of the thermal-insulation portion and is provided to cover the top of the inflatable pool wall. The lower part 25 is also annular, and is connected to the bottom of the thermal-insulation portion and is provided around the pool bottom 14 and at the bottom of the inflatable pool wall. When the thermal-insulation cover 2 is disposed around the inflatable pool wall, and a user wants to move the inflatable pool, due to the support provided to the inflatable pool wall by the lower part 25 of the thermal-insulation cover, the pool body 1 is retained within the bottom of the thermal-insulation cover 2. The inner layer 21 and the outer layer 22 may be connected to each other, for example, by means of at least one of welding, pasting or other adhering, and sewing. The upper part 24 and one or more of the inner layer 21, the outer layer 22, and the intermediate layer 23 may be connected to each other, for example, by means of at least one of welding, pasting or other adhering, and sewing. The lower part 25 and one or more of the inner layer 21, the outer layer 22, and the intermediate layer 23 may be connected to each other, for example, by means of at least one of welding, pasting or other adhering, and sewing.
As shown in
According to one or more example embodiments, when the thermal-insulation cover 2 is disposed around the periphery of the inflatable pool wall of the pool body 1, since the thermal-insulation cover 2 includes a thermal-insulation material layer (e.g. the intermediate layer 23), heat loss from the inflatable pool may be reduced and energy consumption may be reduced. In addition, the thermal-insulation cover 2 does not entirely cover a pool opening defined by the top of the inflatable pool wall, and thus, a user can access the inflatable pool without removing the thermal-insulation cover 2. In this way, the heat preservation and energy saving effect of the thermal-insulation cover 2 is not affected during the use of the inflatable pool.
The thermal-insulation cover 2 can also work in cooperation with a thermal-insulation lid, so that both the top and the sides of the inflatable pool are covered by a thermal-insulation layer to further reduce heat loss, and energy consumption can be further reduced in the process of heating and heat preservation of the inflatable pool.
