Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to an external exhaust heat pump evaporator water receiving tray. Background Technology

[0002] When an air source heat pump operates in a low-temperature environment, the evaporator of the outdoor unit continuously produces condensate, which drips into the evaporator drip tray and then drains into the bottom casing of the machine, eventually exiting through the drain hole in the bottom casing. However, when the ambient temperature is too low, the condensate may not be able to drain in time and will quickly freeze, clogging the evaporator drip tray and the bottom casing. This can lead to water accumulation and freezing inside the equipment, affecting heat exchange efficiency and even damaging the machine. Utility Model Content

[0003] To address the problem that the condensate produced by the evaporator in low-temperature environments easily freezes, causing the evaporator drip tray to fail to drain properly, this utility model provides an externally vented heat pump evaporator drip tray.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An external exhaust heat pump evaporator water receiving tray includes a water receiving tray body, the bottom of the water receiving tray body protruding downward with several supporting feet, the top of the water receiving tray body being recessed downward to form a guide groove, the bottom of the guide groove having several drainage holes; several partitions are fixed inside the guide groove, and each partition is provided with several guide holes.

[0006] Furthermore, the water receiving tray body is approximately L-shaped.

[0007] Furthermore, the top of each of the partitions is lower than the top of the outer wall of the guide channel.

[0008] Furthermore, the diameter of each of the guide holes is smaller than the diameter of the drain hole.

[0009] Furthermore, the inner edge of the guide channel protrudes upward to form a guide plate, and the guide plate is arc-shaped.

[0010] Furthermore, the top of the guide plate is higher than the top of the outer wall of the guide channel.

[0011] Furthermore, the flow channel is divided into a first connecting section and a second connecting section, and there are a total of four partitions. One partition is provided in the first connecting section, and three partitions are provided in the second connecting section.

[0012] Furthermore, each of the partitions has two flow guide holes.

[0013] Furthermore, a heating wire is provided on the inner bottom wall of the flow guide channel.

[0014] The beneficial effects of this invention are as follows: This invention utilizes a partition to prevent direct contact between the evaporator and the guide channel, avoiding the problem of condensate clogging the drain hole and causing poor drainage in low-temperature environments. Even if clogging occurs, the condensate will drain smoothly through the cooperation between the drain hole and the guide plate, preventing the thickened ice layer from damaging the evaporator. In this invention, the guide plate is arc-shaped, which avoids affecting the airflow and airflow resistance, thus preventing interference with the normal heat exchange of the evaporator.

[0018] Figure 4 As shown Figure 3 Top view. Detailed Implementation

[0019] This utility model discloses an external exhaust heat pump evaporator water receiving tray. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0020] Combination Figure 1 and Figure 2 As shown, an external exhaust heat pump evaporator condensate tray includes a tray body, which is approximately L-shaped with several downward-protruding, plate-like support feet 1 at the bottom. The top of the tray body is recessed to form a guide channel, and the bottom of the guide channel has several drain holes 2. Heating wires are laid on the inner bottom wall of the guide channel for heating and preventing condensate from freezing at low temperatures. The guide channel is divided into a first connecting section and a second connecting section, which are connected. A partition 3 is fixed in the first connecting section, and three partitions 3 are fixed in the second connecting section. The top of each partition 3 is lower than the top of the outer wall of the guide channel. Each partition 3 has two guide holes 4, the diameter of which is smaller than the diameter of the drain holes 2. A guide plate 5 protrudes upward from the inner edge of the guide channel. The inner wall of the guide plate 5 is arc-shaped in the vertical direction, and the top of the guide plate 5 is higher than the top of the outer wall of the guide channel.

[0021] Combination Figure 3 and Figure 4As shown, in use, the drip tray body is placed inside the bottom shell 6, which is an open box shape. The drip tray body is located at a corner adjacent to the bottom shell 6, and the corner of the drip tray body has a chamfer, forming a drain hole 8 between the corner of the drip tray and the corner of the bottom shell 6. The outer wall of the drip tray body is fixedly connected to the inner wall of the bottom shell 6, and the height of the top of the outer wall of the drip tray body is the same as the height of the top of the bottom shell. The drip tray body is supported by feet 1, which creates a gap between the bottom of the drip tray body and the inner bottom of the bottom shell 6. The top of the guide plate 5 is higher than the top of the bottom shell 6. The evaporator 7 is placed on each partition 3. In a low-temperature environment, the condensate produced by the evaporator 7 drips into the guide channel and enters the drip tray through the drain hole 2. The partition 3 also has several guide holes 4. The condensate on the partition 3 enters the guide channel through the guide holes 4 and then exits through the drain hole 2 into the guide channel. Heating wires are laid at the bottom of the guide channel to heat the condensate in the channel, preventing it from freezing and clogging the drain hole 2 in low-temperature environments, thus ensuring smooth drainage into the bottom shell 6. If the heating wires are damaged or other problems occur, and the condensate freezes and clogs the drain hole 2, preventing drainage into the bottom shell 6, the condensate in the guide channel will accumulate. Because the guide plate 5 is higher than the bottom shell 6, the accumulated condensate will drain directly into the bottom shell 6 through the drain hole 8. If the condensate clogs both the drain hole 2 and the drain hole 8, the accumulated condensate will drain directly out of the bottom shell 6 through the side wall, preventing disruption to the normal operation of the evaporator 7. The guide plate 5 is arc-shaped in the vertical direction, effectively reducing air intake resistance and preventing interference with the normal heat exchange of the evaporator 7.

[0022] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
