Description

Technical Field

[0001] The utility model relates to the technical field of air energy heat pump swimming pool machines, in particular to a drainage structure for low-temperature defrosting of an air energy heat pump swimming pool machine. Background Art

[0002] Air-source heat pump swimming pool machines are generally equipped with a refrigeration system. In heating mode, condensed water will be generated on the main unit, which needs to be drained. Generally, the chassis of the swimming pool machine is designed with multiple sinking holes (drain holes) as a drainage structure. Users connect the drain nozzle to the sinking hole to connect the drain hose to drain the condensed water on the chassis.

[0003] When the drainage structure of the above-mentioned sinking holes encounters an ambient temperature below 0℃, condensed water will quickly freeze into ice, and the sinking holes will be easily blocked by freezing, which will easily cause the water on the chassis to be unable to drain away. As the water accumulates more and more, it will form large ice blocks on the chassis and freeze the fan blades. In this way, the fan blades of the outdoor unit cannot operate normally, and the machine will report a fault and shut down.

[0004] The air energy heat pump swimming pool machine disclosed in the patent publication number CN212227294U is shown in the accompanying drawings of the specification. Figure 3 The air-source heat pump swimming pool machine discharges condensed water by setting up several sinking holes. However, when this design encounters an ambient temperature below 0°C, the sinking holes (drain holes) are prone to ice blockage. Utility Model Content

[0009] As a further improvement of the above technical solution, the inclined surface is in the shape of an elongated strip.

[0010] As a further improvement of the above technical solution, the bottom end of the inclined surface is connected to a horizontal plane, and the drainage hole is arranged on the horizontal plane.
