The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1 As shown, a low-temperature anti-icing air source heat pump includes a base 1, a heat exchanger 2, a water receiving tray 3, an electric heating wire 4 and a fan (not shown in the figure);

[0026] The base 1 includes a device cavity 11 arranged at the bottom and a heat exchange cavity 12 arranged at the top. The heat exchange cavity 12 includes a fan installation port 121 arranged at the top, a front air inlet and a rear air inlet. The device cavity 11 is used to install a compressor and a liquid collecting tank.

[0027] The heat exchanger 2 has upper and lower openings and side openings;

[0028] The water receiving tray 3 is provided with inclined support surfaces 31 on both sides in the width direction and water collecting grooves 32 along the length direction;

[0029] The inclined support surface 31 is provided with heat exchangers 2 respectively and the heat exchangers 2 are perpendicular to the inclined support surface 31, one heat exchanger 2 corresponds to the front air inlet, and the other heat exchanger 2 corresponds to the rear air inlet. The opening ends of the heat exchangers 2 on the two inclined support surfaces 31 are provided with sealing plates 5 to form an air outlet cavity and communicate with the fan installation port 121. The fan is arranged on the fan installation port 121; the electric heating wire 4 is arranged in the water collecting tank 32. With such a design, the condensed water of the heat exchanger 2 flows to the inclined support surface 31, and then quickly enters the water collecting tank 32 for discharge. Due to the arrangement of the electric heating wire, it is effective in preventing ice.

[0030] As a further improvement of the present invention: the bottom plate of the water collecting tank 32 has a slope along the length direction from one end to the other end.

[0031] The water receiving tray 3 is in the shape of a trapezoid or an equilateral triangle, and the two waist surfaces are respectively inclined support surfaces 31, and a water collecting trough 32 is arranged at the lower end of the inclined support surface 31; or in other words: the water collecting trough 32 is arranged on both sides of the trapezoid or equilateral triangle.

[0032] The top of the heat exchange chamber 12 is provided with two fan installation openings 121 ; the heat exchanger 2 is provided with four.

[0033] As a further improvement of the utility model: the bottom plate of the water collecting tank 32 is provided with a drainage hole, and also includes a drainage pipe 5;

[0034] The upper end of the drain pipe 5 is connected to the drain hole, and the lower end extends out through the device cavity 11 . The electric heating wire 4 extends into the upper end of the drain pipe 6 .
