Description

Technical Field

[0001] The invention relates to the technical field of heat pump equipment, and in particular to a water receiving pan of an external discharge heat pump evaporator. Background Art

[0002] When the air source heat pump is running in a low temperature environment, the evaporator of the outdoor unit will continuously produce condensed water, which will drip into the evaporator water tray, then be discharged into the machine bottom shell, and then be discharged from the machine through the drainage hole of the machine bottom shell. However, when the ambient temperature is too low, the condensed water will not be discharged in time and will quickly freeze, blocking the evaporator water tray and bottom shell, causing water accumulation and freezing in the equipment, affecting the heat exchange efficiency and even freezing the machine. Summary of the invention

[0003] In view of the problem that the condensed water generated by the above-mentioned evaporator in a low temperature environment is easy to freeze, resulting in the evaporator water receiving pan being unable to drain water normally, the present invention provides an external discharge heat pump evaporator water receiving pan.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An external exhaust heat pump evaporator water tray includes a water tray body, the bottom of the water tray body protrudes downward with a plurality of support legs, the top of the water tray body is recessed downward to form a guide groove, the bottom of the guide groove has a plurality of drainage holes; a plurality of partitions are fixed in the guide groove, each of the partitions is provided with a plurality of guide holes. The inner edge of the guide groove protrudes upward to form a guide plate, and the guide plate is arc-shaped.

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

[0007] Furthermore, the top of each partition is lower than the top of the outer side wall of the guide groove.

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

[0009] Furthermore, the top of the guide plate is higher than the top of the outer side wall of the guide groove.

[0010] Furthermore, the guide groove is divided into a first connecting section and a second connecting section, and there are four partitions in total. One partition is arranged in the first connecting section, and three partitions are arranged in the second connecting section.

[0011] Furthermore, each of the partitions has two guide holes.

[0012] Furthermore, a heating wire is arranged on the inner bottom wall of the guide groove.

[0013] The beneficial effects of the present invention are as follows: the present invention uses a partition to prevent direct contact between the evaporator and the guide groove, avoiding the problem of condensed water blocking the drainage hole in a low temperature environment and causing poor drainage, and even if blockage occurs, the condensed water will be smoothly discharged under the cooperation between the drainage hole and the guide plate, avoiding the thickened ice layer from damaging the evaporator. The guide plate in the present invention is arc-shaped, which can avoid affecting the air intake volume and air intake resistance, and avoid affecting the normal heat exchange of the evaporator.

[0018] The present invention discloses a water receiving pan for an external exhaust heat pump evaporator. An implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings.

[0019] Combination Figure 1 and Figure 2 As shown, a water receiving pan of an external exhaust heat pump evaporator includes a water receiving pan body, which is approximately L-shaped and has a plurality of plate-shaped support legs 1 protruding downward at the bottom. The top of the water receiving pan body is recessed downward to form a guide groove, and the bottom of the guide groove has a plurality of drainage holes 2. A heating wire is laid on the inner bottom wall of the guide groove for heating to prevent condensed water from freezing in a low temperature environment. The guide groove is divided into a first connecting section and a second connecting section, the first connecting section is connected to the second connecting section, a partition 3 is fixed in the first connecting section, and three partitions 3 are fixed in the second connecting section, and the top of each partition 3 is lower than the top of the outer wall of the guide groove. Each partition 3 has two guide holes 4, and the diameter of the guide hole 4 is smaller than the diameter of the drainage hole 2. The inner edge of the guide groove protrudes upward to form a guide plate 5, and the inner wall of the guide plate 5 is arc-shaped along the up and down direction, and the top of the guide plate 5 is higher than the top of the outer wall of the guide groove.

[0020] Combination Figure 3 and Figure 4As shown, when in use, the water receiving tray body is placed in the bottom shell 6, and the bottom shell 6 is in an open box shape. The water receiving tray body is located at a corner position adjacent to the bottom shell 6, and the corner of the water receiving tray body has a chamfer, and a drain hole 8 is formed between the corner of the water receiving tray and the corner of the bottom shell 6. The outer wall of the water receiving 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 water receiving tray body is the same as the height of the top of the bottom shell. The water receiving tray body is supported by the support foot 1 so that there is a gap between the bottom of the water receiving 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, which is approximately L-shaped, is placed on each partition 3. In a low temperature environment, the condensed water generated by the evaporator 7 drips into the guide groove and enters the water receiving tray through the drainage hole 2. The partition 3 also has a plurality of guide holes 4. The condensed water located on the partition 3 will enter the guide through the guide hole 4, and then be discharged from the guide groove through the drainage hole 2. A heating wire is laid at the bottom of the guide groove, which can heat the condensed water in the guide groove to avoid the problem of condensed water freezing and blocking the drain hole 2 in a low temperature environment, and ensure that the condensed water can be smoothly discharged into the bottom shell 6. When the heating wire is damaged or other problems occur, if the condensed water freezes and blocks the drain hole 2, the condensed water cannot be discharged into the bottom shell 6, and the condensed water in the guide groove continues to accumulate. Since the guide plate 5 is higher than the bottom shell 6, the accumulated condensed water will be directly discharged into the bottom shell 6 through the drain hole 8; if the condensed water blocks the drain hole 2 and the drain hole 8 at the same time, the accumulated condensed water will be directly discharged from the bottom shell through the side wall of the bottom shell 6 to avoid affecting the normal operation of the evaporator 7. The guide plate 5 is arc-shaped in the up and down direction, which effectively reduces the intake resistance and avoids affecting the normal heat exchange of the evaporator 7.

[0021] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
