Description
Technical Field
The invention relates to the technical field of air conditioning, in particular to an outdoor unit and an air conditioner comprising the same.
Background
When the air conditioner is used for heating at a low temperature, when the surface temperature of a heat exchanger of the outdoor unit is lower than the dew point temperature of air, a frost layer is formed on the surface of the heat exchanger by water vapor in the air, and the frost layer becomes thicker and thicker under long-time heating operation of the air conditioner, so that the heat exchanger of the outdoor unit needs to be defrosted necessarily.
When the air conditioner enters a defrosting mode, condensed water flows to the chassis of the outdoor unit along the heat exchanger of the outdoor unit and is discharged by the water discharge hole on the chassis of the outdoor unit. At this time, the outdoor environment temperature is very low, so that condensed water on the chassis is not drained out of the chassis in time and is condensed into ice, and the ice formed by the condensed water blocks the drain hole for a long time, so that the condensed water is accumulated. The more the accumulated condensed water is, the thicker and thicker the condensed ice is, the lighter the condensed ice causes the heat exchanger to deform to influence the heat exchange effect of the heat exchanger, and the heavier the condensed ice collides with the fan blade by friction to generate great potential safety hazard.
The traditional mode for preventing the chassis from icing mainly comprises the following steps: firstly, a heat conduction pipe is arranged at the periphery of a drain hole of a chassis, and heat radiation of the heat conduction pipe is adopted to melt ice and discharge the ice through the drain hole, but the mode has complex cost structure and higher cost; secondly, adopt the refrigerant pipe deicing, deicing portion and refrigerant pipe intercommunication and deicing portion set up in drain hole department, and deicing portion is used for circulation refrigerant ice to pass through the refrigerant and to the drain hole deicing, but this kind of mode is simple and the cost is lower, but the refrigerant pipe deicing that extends can greatly reduced the efficiency of unit.

The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present invention provides an air conditioner, which includes an outdoor unit 100 and an indoor unit connected to each other, wherein the outdoor unit 100 is installed outdoors, and the indoor unit is installed indoors to cooperate with the outdoor unit 100 to realize cooling and heating of an indoor environment.
The outdoor unit 100 includes a chassis 10 and a heat exchanger 20, the heat exchanger 20 is coupled to the chassis 10, the chassis 10 plays a role of supporting the heat exchanger 20, and the heat exchanger 20 is used for exchanging heat with an outdoor environment to cooperate with an indoor unit to realize cooling and heating of an indoor environment.
As described in the background art, in the air conditioner, when heating at a low temperature, the surface temperature of the heat exchanger 20 of the outdoor unit 100 is lower than the dew point temperature of air, and the frost layer is formed on the surface of the heat exchanger 20 by the water vapor in the air, and the frost layer becomes thicker and thicker in the long-term heating operation of the air conditioner, so that it is necessary to defrost the heat exchanger 20 of the outdoor unit 100. When the air conditioner is defrosted, condensed water flows to the base plate 10 along the heat exchanger 20 and is discharged through a drain hole in the base plate 10. Because the outdoor environment temperature is low, the condensed water is not discharged out of the base plate 10 in time and is condensed into ice, and the ice can be frozen for a long time to cause the blockage of a drainage hole, so that the condensed water is accumulated. The more the accumulated condensed water is, the thicker and thicker the condensed ice is, the lighter the condensed ice causes the heat exchanger 20 to deform to influence the heat exchange effect of the heat exchanger 20, and the heavier the condensed ice collides with the fan blades by friction, so that great potential safety hazards are generated.
Specifically, the chassis 10 has a missing position 11 thereon, and the missing position 11 is disposed opposite to the bottom end 21 of the heat exchanger 20. During defrosting, the condensed water on the heat exchanger 20 flows to the bottom end 21 thereof under the action of gravity, and because the chassis 10 has the missing position 11 at the position facing the heat exchanger 20, the condensed water at the bottom end 21 of the heat exchanger 20 directly flows to the outside from the missing position 11. Therefore, the condensed water does not need to flow through the chassis 10, and the condition that the drain hole is blocked due to the fact that the condensed water is frozen on the chassis 10 is avoided, so that the heat exchange efficiency of the heat exchanger 20 is guaranteed, and the safety is improved.
Referring to fig. 3, in an embodiment, the bottom end 21 of the heat exchanger 20 includes a middle section 211, and a head section 212 and a tail section 213 respectively connected to two ends of the middle section 211, wherein the head section 212 and the tail section 213 are supported on the chassis 10, and the middle section 211 is disposed opposite to the defect 11. It is understood that in other embodiments, all of the bottom end 21 of the heat exchange unit may be disposed opposite to the defect site 11, which is not limited herein.
Further, the cross-sectional area of the intermediate section 211 is greater than the sum of the cross-sectional area of the head section 212 and the cross-sectional area of the tail section 213. In this way, the contact area between the heat exchanger 20 and the chassis 10 can be reduced, so that the area of the heat exchanger 20 facing the missing position 11 is increased, and thus the condensed water can flow to the outside from the missing position 11.
Specifically, the contact area of the head section 212 and the chassis 10 is 25mmx37mm, and the contact area of the tail end 213 and the chassis 10 is 45mmx32 mm.

Referring to fig. 4, specifically, the chassis 11 includes a first body 14, and a first assembling portion 12 and a second assembling portion 13 connected to the first body 14, wherein a head section 212 of the bottom end 21 of the heat exchanger 20 is assembled to the first assembling portion 12, and a tail section 213 of the bottom end 21 of the heat exchanger 20 is assembled to the second assembling portion 13. A space is provided between the bottom surface of the first fitting portion 12 and the bottom surface of the first body 14, and a space is also provided between the bottom surface of the second fitting portion 13 and the bottom surface of the first body 14. In this way, when the chassis 10 is placed on the ground, the bottom surface of the first body 14 contacts with the ground, and the bottom surfaces of the first assembling portion 12 and the second assembling portion 13 do not contact with the ground, so that the distance between the heat exchanger 20 and the ground can be increased, and the condensed water can flow away conveniently instead of being accumulated between the heat exchanger 20 and the ground.
