Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air conditioning, and in particular to an outdoor device of an air conditioner and the air conditioner. Background Art
[0002] When frost forms on the outdoor heat exchanger inside the outdoor unit due to the heating operation of the air conditioner, a defrost operation, which operates in reverse cycle to the heating operation, is performed to melt the frost. During the defrost operation, the outdoor heat exchanger functions as a condenser, releasing heat and melting the frost. The resulting water flows down the outdoor heat exchanger and collects on the floor beneath the outdoor unit, where it is then drained from a drain port located in the floor.
[0003] In severely cold environments where the outdoor temperature remains below freezing, during this defrost operation, the water flowing onto the baseplate to be drained cools and freezes before reaching the drain outlet, preventing it from being discharged. This frozen drain water gradually accumulates and thickens on the baseplate, ultimately damaging the outdoor heat exchanger or outdoor fan. Furthermore, even if the drain water does not freeze during its flow, snow or other substances may be blown onto the interior of the outdoor unit or onto the baseplate, hindering its discharge. Consequently, this undischarged drain water may freeze, potentially damaging the outdoor heat exchanger and other components. Summary of the Invention

[0005] One embodiment of the present invention also provides an air conditioner, which has a refrigeration unit, and the refrigeration unit includes: a compressor that compresses the refrigerant; an indoor heat exchanger that performs heat exchange between the refrigerant and the indoor air; an expansion valve that decompresses and expands the refrigerant; and an outdoor heat exchanger that performs heat exchange between the refrigerant and the outdoor air. The air conditioner also has the outdoor equipment described above, and the outdoor equipment includes the compressor and the outdoor heat exchanger.
[0006] According to the above structure, the air conditioner of the present invention is provided with an auxiliary drain outlet. When the amount of condensed water is large, even if the first main drain outlet cannot be discharged in time, the accumulated condensed water will flow to the auxiliary drain area and be discharged from the auxiliary drain outlet, thereby preventing the condensed water from freezing.

[0016] Hereinafter, an air conditioner according to an embodiment of the present invention will be described with reference to the drawings. Figure 1 A schematic diagram of the refrigeration cycle unit of the air conditioner of the present invention. Figure 1 As shown, the air conditioner 100 is configured by connecting an outdoor device 10 disposed outdoors and an indoor device 30 disposed indoors through pipes and the like.
[0017] Please refer to Figures 2 to 4The outdoor device 10 includes an outdoor unit housing 11, a compressor 12, a four-way valve 13, an outdoor heat exchanger 14, an expansion valve 15, an antifreeze pipe 16, an on-off valve 17, and an outdoor fan 18. The outdoor unit housing 11 houses components such as the compressor 12, the outdoor heat exchanger 14, the antifreeze pipe 16, and the outdoor fan 18. The indoor device 30 includes an indoor unit housing (not shown), an indoor heat exchanger 32, and an indoor fan 34. The indoor unit housing houses the indoor heat exchanger 32, the expansion valve 15, and the indoor fan 34.
[0018] The air conditioner 100 includes a refrigeration cycle unit, which is configured by sequentially connecting a compressor 12 , a four-way valve 13 , an outdoor heat exchanger 14 , an expansion valve 15 , and an indoor heat exchanger 32 via piping.
[0019] The following is a detailed description of each component of the refrigeration cycle unit.
[0020] Among them, the compressor 12 is a mechanism that compresses low-pressure refrigerant to high pressure in the refrigeration cycle device. The compressor 12 is, for example, a compressor 12 that is driven to rotate by a motor. The motor of the compressor 12 can control the speed (frequency) by an inverter or the like. Specifically, the compressor 12 includes a discharge portion 121 and a suction portion 122, and the discharge portion 121 and the suction portion 122 are respectively connected to different connection ports of the four-way valve 13. When the compressor 12 is in operation, it sucks in low-pressure refrigerant from the suction portion 122, compresses the refrigerant to generate high-pressure refrigerant, and then discharges the compressed refrigerant from the discharge portion 121.
[0021] The four-way valve 13 is a valve that switches the circulation direction of the refrigerant corresponding to cooling operation or heating operation in the refrigeration cycle device, and is connected to the discharge part 121 of the compressor 12, the suction part 122 of the compressor 12, the outdoor heat exchanger 14 and the indoor heat exchanger 32 via piping.
[0022] The expansion valve 15 expands and reduces the pressure of the refrigerant flowing between the outdoor heat exchanger 14 and the indoor heat exchanger 32. The expansion valve 15 is, for example, an electric expansion valve 15 whose opening can be controlled. During cooling operation, the expansion valve 15 reduces the pressure of the high-pressure refrigerant after heat dissipation in the outdoor heat exchanger 14 before transferring it to the indoor heat exchanger 32. Furthermore, during heating operation, the expansion valve 15 reduces the pressure of the high-pressure refrigerant after heat dissipation in the indoor heat exchanger 32 before transferring it to the outdoor heat exchanger 14.
[0023] The outdoor heat exchanger 14 is housed in the outdoor unit housing 11 and is disposed opposite the outdoor fan 18 to exchange heat between the air drawn into the outdoor unit 10 by the outdoor fan 18 and the refrigerant. The outdoor heat exchanger 14 functions as an evaporator during cooling operation and as a condenser during heating operation.
[0024] The indoor heat exchanger 32 performs heat exchange between the air drawn into the indoor device 30 by the indoor fan 34 and the refrigerant. The indoor heat exchanger 32 functions as a condenser during cooling operation and as an evaporator during heating operation.
[0025] The antifreeze pipe 16 is provided on the bottom surface of the outdoor unit housing 11 and is arranged so as to be located between the outdoor heat exchanger 14 and the bottom surface of the outdoor unit housing 11 in a plan view.
[0026] Hereinafter, various operation modes of the air conditioner 100 will be described.
[0027] (1) Refrigeration operation
[0028] When the air conditioner 100 is in cooling operation, the solenoid valve is in a closed state, the control unit controls the operation of the four-way valve 13, and the refrigerant is discharged through the discharge portion 121 of the compressor 12, and passes through the four-way valve 13, the outdoor heat exchanger, the expansion valve 15, the indoor heat exchanger, the four-way valve 13 in sequence, and is finally sucked into the compressor 12 to complete the refrigeration cycle and repeat the cycle.
[0029] (2) Heating operation
[0030] When the air conditioner 100 is in heating operation, the control unit controls the operation of the four-way valve 13, and the refrigerant is discharged from the discharge portion 121 of the compressor 12, and then passes through the four-way valve 13, the indoor heat exchanger 32, the expansion valve 15, the outdoor heat exchanger 14, the four-way valve 13 in sequence, and finally is sucked into the compressor 12 by the suction portion 122 of the compressor 12 to complete the heating cycle and repeat the cycle.
[0031] (3) Defrost operation
[0032] The first part of the refrigerant discharged from the discharge part 121 of the compressor 12 passes through the four-way valve 13, the outdoor heat exchanger 14, the expansion valve 15, the indoor heat exchanger 32, the four-way valve 13 in sequence, and is finally sucked into the compressor 12 by the suction part 122 of the compressor 12. The second part of the refrigerant passes through the on-off valve 17 and the antifreeze pipe 16 in sequence and merges with the first part of the refrigerant, and passes through the outdoor heat exchanger, the expansion valve 15, the first indoor heat exchanger 32, the four-way valve 13 in sequence, and is finally sucked into the compressor 12 by the suction part 122 of the compressor 12.
[0033] Hereinafter, the outdoor unit housing 11 of the present invention will be described.
[0034] Please refer to Figures 5 to 7The outdoor unit housing 11 includes a bottom plate 111, surrounding side plates 112, a top plate 113, a base 114, and at least one first waterproof member 115 and a second waterproof member 116. The bottom plate 111, side plates 112, and top plate 113 collectively form a housing space (not shown) that accommodates components such as the compressor 12, outdoor heat exchanger 14, antifreeze pipe 16, and outdoor fan 18. The base 114 is disposed at the bottom of the bottom plate 111 and supports the outdoor unit housing 11.
[0035] In this embodiment, the base plate 111 has a rectangular plate-like structure and includes a first drain area 21, a second drain area 22, an auxiliary drain area 23, a first receiving area 24, and a second receiving area 25. The first drain area 21 is located along one of the long sides of the base plate 111, while the second drain area 22 is located along one of the short sides of the base plate 111. One end of the first drain area 21 is connected to one end of the second drain area 22, thereby forming an L-shaped main drain area. This main drain area is located below the outdoor heat exchanger 14 and is arranged along the shape of the outdoor heat exchanger 14. Condensate dripping from the outdoor heat exchanger 14 falls into the first and second drain areas 21, 22, allowing for drainage.
[0036] The first loading area 24 is positioned adjacent to the first drainage area 21 and protrudes from the first drainage area 21. The outdoor fan 18 is mounted in the first loading area 24. The auxiliary drainage area 23 is positioned adjacent to one side of the first loading area 24, parallel to the first drainage area 21, and connected to the first drainage area 21. Rainwater entering through the opening of the outdoor unit housing 11 is drained through the auxiliary drainage area 23 and the first drainage area 21. The second loading area 25 is located at the other end of the auxiliary drainage area 23, away from the first loading area 24. The compressor 12 is mounted in the second loading area 25. In this embodiment, the first loading area 24, the auxiliary drainage area 23, and the second loading area 25 are arranged in sequence along the longitudinal direction of the first drainage area 21.
[0037] Specifically, the first drainage area 21 is elongated and has an inverted trapezoidal interface. Specifically, the first drainage area 21 includes a lowest surface 2101 and a first inclined surface 2103 and a second inclined surface 2105 extending upward from either end of the lowest surface 2101. First main drainage outlets 211 are formed through the lowest surface 2101, the first inclined surface 2103, and the second inclined surface 2105, respectively. These three first main drainage outlets 211 are spaced apart from one another.
[0038] The three first main drain ports 211 are spaced apart along the length direction of the bottom plate 111 and are used to drain condensed water during the defrosting operation to the outside.
[0039] In this embodiment, please refer to Figure 8 Three first main drain outlets 211 are provided in the first drain area 21. Each first main drain outlet 211 is in the shape of an elongated ellipse. The middle first main drain outlet 211 is located at the lowest surface of the first drain area 21, so that when the condensed water flows down from the first inclined surfaces 2103 and the second inclined surfaces 2105 on both sides of the first drain area 21, part of the condensed water is discharged from the first main drain outlets 211 on the first inclined surfaces 2103 and the second inclined surfaces 2105, and part of the condensed water flows along the first inclined surfaces 2103 and the second inclined surfaces 2105 to the lowest surface 2101 of the first drain area 21 and is discharged from the first main drain outlets 211 on the lowest surface 2101, thereby discharging the condensed water in time and preventing the condensed water from freezing again and blocking the drain outlet.
[0040] Furthermore, in this embodiment, the first drainage area 21 is further provided with a drainage hole 212 for draining condensed water. The drainage hole 212 corresponds to a substantially central position of an auxiliary drainage port 231 described later.
[0041] The second drainage area 22 is adjacent to and communicates with the first drainage area 21. A plurality of second main drainage outlets 221 are provided in the second drainage area 22. These outlets 221 are arranged so as not to overlap with the base 114. This prevents the outlets 221 from being blocked by the base 114 and affecting drainage efficiency. This increases drainage volume and accelerates drainage.
[0042] Furthermore, in this embodiment, the plurality of second main drain ports 221 are arranged along the extension direction of the antifreeze pipe 16, that is, the antifreeze pipe 16 is arranged in a manner of passing through the plurality of second main drain ports 221. Of course, in other embodiments, the antifreeze pipe 16 may also be arranged along the edge of the second drain area 22, which is not limited here.
[0043] In this embodiment, the multiple second main drain outlets 221 are shown in different shapes. In other embodiments, the multiple second main drain outlets 221 can also be the same shape, a circular shape or an elongated elliptical shape, which is not limited here.
[0044] In this embodiment, the plurality of second main drain ports 221 and the plurality of first main drain ports 211 constitute a main drain port.
[0045] Please refer to Figure 9 The auxiliary drainage area 23 is closer to the center of the bottom plate 111 than the first drainage area 21, and the auxiliary drainage area 23 is a third inclined surface that gradually slopes downward from the center of the bottom plate 111 toward the first drainage area 21, and the third inclined surface is connected to the first drainage area 21.
[0046] In this embodiment, the auxiliary drainage area 23 is a recess formed between the first loading area 24 and the second loading area 25, and is gradually inclined downward from the center of the bottom plate 111 toward the first drainage area 21 to form a certain slope, so that water in other areas of the bottom plate 111 can flow to the first drainage area 21, and can prevent the accumulated water in the first drainage area 21 from flowing to other parts of the bottom plate 111.
[0047] Furthermore, the auxiliary drain area 23 is provided with an auxiliary drain port 231, extending in the same direction as the multiple first main drain ports 211. This allows water in the first drain area 21 to be promptly drained through the auxiliary drain port 231, even if it fails to drain immediately, further preventing condensed water from freezing. Furthermore, connecting ribs 27 are formed at the junctions between the auxiliary drain area 23 and the first loading area 24, and at the junctions between the auxiliary drain area 23 and the second loading area 25.
[0048] It should be noted that during defrost operation, frost attached to the outdoor heat exchanger 14 melts, forming condensed water that drips onto the bottom plate 111 of the outdoor unit housing 11. The accumulated condensed water is then discharged from the first main drain port 211 and the second main drain port 221 to the outside of the outdoor unit housing 11. At this time, if the temperature inside the outdoor unit 10 drops below freezing, the condensed water accumulated on the bottom plate 111 may freeze, thereby affecting subsequent condensed water discharge. By providing the auxiliary drain port 231, even if the first main drain port 211 and the second main drain port 221 are unable to drain the condensed water in a timely manner, the accumulated condensed water will flow to the auxiliary drain area 23 and be discharged from the auxiliary drain port 231 in the event of a large amount of condensed water. This prevents the condensed water from freezing.
[0049] Furthermore, in this embodiment, the auxiliary drain outlet 231 is in a generally elongated elliptical shape, and extends in the same direction as the plurality of first main drain outlets 211. Of course, in other embodiments, the auxiliary drain outlet 231 may be configured in other shapes. For example, the auxiliary drain outlets 231 may be arranged in sequence in a direction perpendicular or parallel to the direction in which the plurality of first main drain outlets 211 extend. This is not a limitation herein.
[0050] Furthermore, in this embodiment, by providing an auxiliary drain port 231 in the auxiliary drain area 23, on the one hand, drainage can be assisted, and on the other hand, when water flows from the central part or the front side of the bottom plate 111 to the first drain area 21, the water can also be guided to the first drain area 21 and discharged through the auxiliary drain port 231 and the first main drain port 211 to avoid the first main drain port 211 of the first drain area 21 from not being able to drain water, thereby preventing condensed water from freezing.
[0051] The first mounting area 24 is used to mount the outdoor fan 18 so that the outdoor fan 18 is disposed opposite the outdoor heat exchanger. The first mounting area 24 is higher than the first main drain area and the auxiliary drain area 23 to avoid affecting the circuit of the outdoor fan 18.
[0052] The second placement area 25 is located on a side of the bottom plate 111 away from the second drainage area 22 and is used for placing components such as the compressor 12 .
[0053] At least one first waterproof member 115 is disposed at at least one end of the side of the auxiliary drain outlet 231 away from the first drain area 21 and extends to the first receiving area 24 or the second receiving area 25. In this embodiment, the at least one first waterproof member 115 comprises two first waterproof members 115: one first waterproof member 115 is installed at the junction between the auxiliary drain area 23 and the first receiving area 24 and connected to the rib 27, and the other first waterproof member 115 is installed at the junction between the auxiliary drain area 23 and the second receiving area 25 and connected to the rib 27. This prevents condensed water that is not discharged from the first main drain outlet 211 from penetrating into the central portion of the bottom plate 111, and directs the condensed water toward the auxiliary drain outlet 231, thereby allowing the accumulated condensed water to be discharged from the auxiliary drain outlet 231.
[0054] The second waterproof member 116 is located at the junction of the first receiving area 24 and the second drain area 22, corresponding to the position where the first drain area 21 and the second drain area 22 communicate. When condensed water drips into the second drain area 22, the second waterproof member 116 blocks the condensed water from flowing into the central portion of the bottom plate 111. Instead, the second waterproof member 116 guides the condensed water along the first inclined surface 2103 of the first drain area 21 and into the first drain area 21, where it is discharged through the first main drain port 211. Therefore, when a large amount of condensed water is present, the second waterproof member 116 prevents the condensed water from flowing from the second drain area 22 to the central portion of the bottom plate 111, thereby protecting other components located in the central portion of the bottom plate 111.
[0055] The antifreeze pipe 16 is arranged in the first drainage area 21 and the second drainage area 22. In the first drainage area 21, a portion of the antifreeze pipe 16 is located between the first main drain outlet 211 of the first drainage area 21 and the auxiliary drainage area 23. Therefore, even if the condensed water in the first loading area 24 freezes, when it thaws through the antifreeze pipe 16, the melted water can pass through the auxiliary drainage area 23 instead of flowing into the central position of the bottom plate 111.
[0056] Furthermore, a plurality of fasteners 28 are provided on the bottom plate 111 , and the plurality of fasteners 28 are used to fix the antifreeze pipe 16 on the bottom plate 111 .
[0057] The embodiments of the present invention are illustrative in all respects and should not be construed as limiting. The scope of the present invention is indicated not by the above description but by the scope of the claims, and is intended to encompass all modifications within the meaning and scope equivalent to the claims. Furthermore, configurations obtained by combining the configurations of the different embodiments described in this specification are also included within the scope of the present invention.
