Technical Field

[0001] The present application relates to the technical field of air-conditioning equipment, and in particular to an air conditioner. Background Art

[0002] In the related art, the air conditioner includes a shell, a heat exchanger and a main water receiving pan. The heat exchanger and the main water receiving pan are arranged in the shell, and the main water receiving pan is arranged on the bottom side of the heat exchanger. In order to reduce the thickness of the air conditioner and meet the installation requirements of limited space, the heat exchanger is tilted without reducing the volume of the heat exchanger to reduce the space occupied by the heat exchanger. However, when the heat exchanger is working, part of the condensed water condensed on the surface of the heat exchanger flows along the inclined surface of the heat exchanger to the main water receiving pan, while the other part, under the action of gravity, directly drips downward and cannot be received by the main water receiving pan, so it drips on the shell or enters the room from the air inlet of the shell, affecting the user experience.

[0048] In the description of the embodiments of the present application, it should be noted that the directions or positional relationships indicated by terms such as "height direction", "up", "down", "top", "bottom", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments of the present application.

[0049] In addition, it should be noted that in the description of the present invention, 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The present application embodiment provides an air conditioner 1, see Figures 1 to 9 , including a shell 10, a heat exchanger 11 and a water receiving tray assembly 12.

[0051] The housing 10 has an air inlet 10a and an air outlet 10b. The heat exchanger 11 is disposed in the housing 10 and is obliquely disposed on the top side of the air inlet 10a. The heat exchanger 11 has a windward surface 11a.

[0052] Specifically, the airflow in the external environment enters the housing 10 through the air inlet 10a, and is discharged to the indoor space from the air outlet 10b after heat exchange in the heat exchanger 11, thereby adjusting the temperature or humidity of the indoor space.

[0053] Specifically, see Figure 4 The windward surface 11a refers to the side surface of the heat exchanger 11 facing the air inlet 10a. Correspondingly, the side surface of the heat exchanger 11 away from the air inlet 10a is the leeward side 11b of the heat exchanger 11. The airflow in the external environment contacts the heat exchanger 11 through the windward surface 11a and leaves the heat exchanger 11 through the leeward surface 11b.

[0054] It can be understood that the heat exchanger 11 is tilted and arranged on the top side of the air inlet 10a, which means that the heat exchanger 11 has an angle with the horizontal direction, and the horizontal direction refers to the direction parallel to the ground when the air conditioner 1 is in normal use. Exemplarily, the heat exchanger 11 is arranged in the housing 10, and along the direction from the bottom side to the top side, the heat exchanger 11 extends tilted toward the rear side. Here, the rear side refers to the side away from the air outlet 10b when the air conditioner 1 is in normal use. The air outlet 10b is arranged on the front side, and the air inlet 10a is located on the rear side.

[0055] The inclined setting of the heat exchanger 11 can reduce the thickness of the air conditioner 1 without reducing the volume of the heat exchanger 11, thereby meeting the installation requirements in a limited space. In addition, it can also guide the airflow passing through the heat exchanger 11 so that the airflow can be blown out toward the ground at an angle, thereby expanding the range of the airflow blowing toward the ground and improving the user experience.

[0056] It can be understood that the heat exchanger 11 is used to exchange heat with the airflow in the external environment. When the air conditioner 1 is in cooling mode or dehumidification mode, the heat exchanger 11 acts as an evaporator to condense and dehumidify the airflow; when the air conditioner 1 is in heating mode, the heat exchanger 11 acts as a condenser to heat the airflow.

[0057] Take the air conditioner 1 cooling the indoor space as an example. At this time, the heat exchanger 11 acts as an evaporator and exchanges heat with the airflow. At this time, condensed water will be generated on the surface of the heat exchanger 11. Therefore, the embodiment of the present application is provided with a water receiving pan assembly 12 to receive the condensed water dripping from the surface of the heat exchanger 11.

[0058] See also Figure 4 and Figure 5 The water receiving tray assembly 12 is arranged in the shell 10, and the water receiving tray assembly 12 includes a first water receiving tray 121 and a second water receiving tray 122 connected to each other. The first water receiving tray 121 is arranged on the bottom side of the heat exchanger 11, and the first water receiving tray 121 is provided with a first water receiving groove 121a. The second water receiving tray 122 is arranged between the windward surface 11a of the heat exchanger 11 and the air inlet 10a, and the second water receiving tray 122 is provided with a second water receiving groove 122a and an air passage 122b for air flow to pass through.

[0059] It can be understood that the air passage 122b is connected to the air inlet 10a, that is, the air entering through the air inlet 10a can smoothly pass through the air passage 122b and enter the heat exchanger 11 for heat exchange.

[0060] The first water receiving pan 121 and the second water receiving pan 122 jointly receive the condensed water dripping from the surface of the heat exchanger 11. Specifically, a part of the condensed water generated when the heat exchanger 11 is working flows along the inclined surface of the heat exchanger 11, flows into the first water receiving pan 121 at the bottom, and is received by the first water receiving groove 121a, and another part of the condensed water, under the action of gravity, drips downward from the inclined surface of the heat exchanger 11 and is received by the second water receiving groove 122a of the second water receiving pan 122, so that almost all of the condensed water dripping from the heat exchanger 11 is received by the first water receiving pan 121 and the second water receiving pan 122.

[0061] It is understandable that in the related art, the heat exchanger is arranged at an angle, but the air conditioner only has a water collecting pan on the bottom side of the heat exchanger, and part of the structure of the heat exchanger is exposed through the air inlet. Part of the condensed water condensed on the surface of the heat exchanger is easy to drip directly downward under the action of gravity and cannot be received by the water collecting pan, thereby dripping on the shell or entering the room from the air inlet of the shell, affecting the user experience.

[0062] In the embodiment of the present application, the first water receiving tray 121 is arranged on the bottom side of the heat exchanger 11, and the second water receiving tray 122 is arranged between the windward surface 11a of the heat exchanger 11 and the air inlet 10a, so as to effectively receive the condensed water of the heat exchanger 11 and reduce the probability of the condensed water dripping onto the shell 10 or entering the room from the air inlet 10a.

[0063] Exemplarily, the second water receiving pan 122 can also be tilted, and the tilt angle is close to the tilt angle of the heat exchanger 11, so that the second water receiving pan 122 can be set as close to the heat exchanger 11 as possible to collect the condensed water generated by the heat exchanger 11. The second water receiving pan 122 is set to receive the condensed water dripping directly downward from the heat exchanger 11, so the angle of the heat exchanger 11 tilting backward can be smaller. Exemplarily, the tilt angle α of the heat exchanger 11 is not greater than 45°, for example, 45°, 40°, 36°, 30°, 25°, 20°, etc., so as to minimize the space occupied by the heat exchanger 11 and make the overall thickness of the air conditioner 1 smaller.

[0064] The first water receiving tray 121 and the second water receiving tray 122 are of an integrated structure. That is, the first water receiving tray 121 and the second water receiving tray 122 are integrally manufactured, so that the structure of the water receiving tray assembly 12 is more stable, the number of parts of the air conditioner 1 is reduced, and the assembly steps are reduced. There is no connection gap between the first water receiving tray 121 and the second water receiving tray 122, which reduces the probability of condensed water leaking from the connection between the first water receiving tray 121 and the second water receiving tray 122.

[0065] In the air conditioner 1 provided in the embodiment of the present application, the first water receiving pan 121 and the second water receiving pan 122 jointly receive the condensed water generated by the heat exchanger 11, thereby reducing the probability of the condensed water leaking out of the air conditioner 1 or affecting the electrical components of the air conditioner 1, increasing the reliability of the air conditioner 1, meeting the installation requirements in a limited space, and achieving a thinner air conditioner 1. In addition, the integrated design of the first water receiving pan 121 and the second water receiving pan 122 can reduce the number of parts and assembly processes of the air conditioner 1 while achieving effective water collection, further increasing the reliability of water collection.

[0066] The specific structure of the housing 10 is not limited. For example, see Figure 3 The housing 10 includes an upper shell 101 and a panel 102. The top of the upper shell 101 is provided with a structure for fixing to a ceiling or a roof. The panel 102 is installed at the bottom of the upper shell 101 to close the bottom opening of the upper shell 101. The heat exchanger 11 and the water tray component are arranged in a space defined by the upper shell 101 and the panel 102. The air inlet 10a and the air outlet 10b are arranged on the panel 102. Specifically, the air inlet 10a and the air outlet 10b can be respectively located at both ends of the panel 102 along the front-rear direction.

[0067] In some embodiments, in a plane projection perpendicular to the height direction of the air conditioner 1 , a projection of any portion of the windward surface 11 a of the heat exchanger 11 is located within the projection range of the water receiving tray assembly 12 .

[0068] Specifically, the projection of any part of the windward surface 11 a of the heat exchanger 11 is located within the projection range of the first water receiving tray 121 and the second water receiving tray 122 .

[0069] That is to say, all parts of the windward surface 11a of the heat exchanger 11 are within the projection area of ​​the water receiving tray assembly 12. No matter where the condensed water falls from the heat exchanger 11, it can fall into the water receiving tray assembly 12 and be received by the first water receiving tray 121 and the second water receiving tray 122, thereby reducing the probability of condensed water dripping outside the water receiving tray assembly 12.

[0070] For some examples, see Figure 5 , the second water receiving groove 122a is connected to the first water receiving groove 121a; and the position of the second water receiving groove 122a is higher than the first water receiving groove 121a, so that the liquid in the second water receiving groove 122a converges to the first water receiving groove 121a.

[0071] That is to say, the liquids in the first water receiving groove 121a and the second water receiving groove 122a circulate with each other, and there is a height difference between the second water receiving groove 122a and the first water receiving groove 121a. The condensed water received by the second water receiving groove 122a can flow into the first water receiving groove 121a under the action of gravity, thereby reducing the probability of condensed water overflow and reducing the water receiving pressure of the second water receiving groove 122a, improving the collection efficiency of condensed water, and the condensed water can be discharged from the first water receiving groove 121a in a concentrated manner, thereby increasing the drainage reliability.

[0072] The first water receiving groove 121a can discharge the condensed water after confluence. Exemplarily, the first water receiving pan 121 is connected to a water pump component, which is in communication with the first water receiving groove 121a, and the condensed water collected in the first water receiving groove 121a is discharged to the outside of the air conditioner 1 through the water pump component; in other embodiments, the first water receiving groove 121a can also discharge the condensed water by gravity drainage. Of course, the air conditioner 1 can also use a combination of the above two methods to drain water.

[0073] The specific structure of the second water receiving tray 122 is not limited.

[0074] For some examples, see Figure 5The second water receiving tray 122 includes a plurality of water baffles 1221, the water baffles 1221 extend along the first direction, the plurality of water baffles 1221 are arranged along the second direction, and the interval between two adjacent water baffles 1221 defines an air passage 122b, and the water baffles 1221 form a second water receiving groove 122a on the side facing the heat exchanger 11, wherein the first direction, the second direction, and the height direction of the air conditioner 1 intersect each other.

[0075] The number of the water baffles 1221 can be two, three or more, which is not limited here. A plurality of water baffles 1221 can define a plurality of second water receiving grooves 122a to increase water receiving efficiency and water receiving reliability.

[0076] The plurality of water retaining plates 1221 are spaced apart along the second direction, and the second direction may be parallel to the extension direction of the heat exchanger 11 , so as to better receive the condensed water dripping from the heat exchanger 11 .

[0077] It can be understood that the first direction may be perpendicular to the height direction of the air conditioner 1 , and illustratively, the first direction may be the left-right direction.

[0078] A second water receiving groove 122 a is formed on one side of the water baffle plate 1221 facing the heat exchanger 11 , that is, the second water receiving groove 122 a is defined by the structure of the water baffle plate 1221 itself to receive condensed water generated by the heat exchanger 11 .

[0079] The air passage 122b is defined by the interval between two adjacent water baffles 1221. It is understandable that in some embodiments, in a plane projection perpendicular to the height direction of the air conditioner 1, the projections of the two adjacent water baffles 1221 partially overlap, and the overlapping area covers the air passage 122b. In this way, while the air entering from the air inlet 10a can smoothly pass through the air passage 122b to enter the heat exchanger 11 for heat exchange, condensed water can also be prevented from leaking from the air passage 122b to the outside of the water tray assembly 12.

[0080] The first direction may be a front-to-back direction or other directions, which is not limited here.

[0081] Exemplarily, both ends of the water baffle 1221 along the first direction are respectively connected to the first water receiving tray 121 , so that the water baffles 1221 are connected through the first water receiving tray 121 , and the overall structural strength of the water receiving tray assembly 12 is high.

[0082] For some examples, see Figure 5 Along the first direction, the bottom of the second water receiving trough 122a includes a first sub-segment 1221a and a second sub-segment 1221b, the first sub-segment 1221a extends downwardly and obliquely in a direction away from the second sub-segment 1221b, and the second sub-segment 1221b extends downwardly and obliquely in a direction away from the first sub-segment 1221a.

[0083] It should be noted that the bottom of the second water receiving trough 122a refers to the lowest part of the second water receiving trough 122a. The bottom of the second water receiving trough 122a may only include the first sub-segment 1221a and the second sub-segment 1221b along the first direction, that is, the end of the first sub-segment 1221a close to the second sub-segment 1221b is connected to the end of the second sub-segment 1221b close to the first sub-segment 1221a. The bottom of the second water receiving trough 122a may also include the first sub-segment 1221a, the second sub-segment 1221b and at least one other sub-segment. In this case, the first sub-segment 1221a and the second sub-segment 1221b are arranged at intervals and connected through other sub-segments.

[0084] The first subsection 1221a is tilted downward along one end away from the second subsection 1221b, and the second subsection 1221b is tilted downward and extends in a direction away from the first subsection 1221a, that is, the position of the first subsection 1221a away from the second subsection 1221b is lower than the position of the first subsection 1221a near one end of the second subsection 1221b, and the position of the second subsection 1221b away from the first subsection 1221a is lower than the position of the second subsection 1221b near the first subsection 1221a, and the bottom of the first water receiving trough 121a is generally high in the middle and low at both ends. In this way, the condensed water collected by the second water receiving trough 122a can quickly flow to the first water receiving trough 121a along the inclined surfaces of the first subsection 1221a and the second subsection 1221b.

[0085] For some examples, see Figure 7 The cross-sectional shape of the water baffle 1221 perpendicular to the first direction includes a first baffle 12211, a second baffle 12212, a third baffle 12213 and a fourth baffle 12214 connected in sequence.

[0086] The first baffle 12211 and the second baffle 12212 extend in a direction close to each other from the top side to the bottom side, and the two together define the second water receiving groove 122a. Specifically, the first baffle 12211 and the second baffle 12212 extend close to each other from the top side to the bottom side, and can form a concave structure to define the space of the second water receiving groove 122a. The condensed water dripping directly downward from the inclined surface of the heat exchanger 11 gathers in the second water receiving groove 122a, and then flows from the first water receiving groove 121a to the first water receiving groove 121a below.

[0087] The third baffle 12213 extends obliquely upward from the connection with the second baffle 12212 toward the direction close to the heat exchanger 11. In this way, when the condensed water dripping directly downward from the inclined surface of the heat exchanger 11 contacts the third baffle 12213, the third baffle 12213 guides the condensed water, and the condensed water can flow smoothly into the second water receiving groove 122a under the action of the third baffle 12213 to collect the condensed water.

[0088] The fourth baffle plate 12214 extends downward from the connection with the third baffle plate 12213. In this way, when the condensed water dripping directly downward from the inclined surface of the heat exchanger 11 contacts the fourth baffle plate 12214, the fourth baffle plate 12214 can also play a guiding role, so that the condensed water can flow to the second water receiving groove 122a of the water baffle plate 1221 located below, thereby completing the collection of the condensed water.

[0089] Among them, in the plane projection of any two adjacent water baffles 1221 perpendicular to the height direction of the air conditioner 1, the projection of the fourth baffle 12214 of the upper water baffle 1221 and the projection of the first baffle 12211 of the lower water baffle 1221 have an overlapping area.

[0090] In this way, the condensed water received by the fourth baffle 12214 of the upper water baffle 1221 can directly drip onto the first baffle 12211 of the lower water baffle 1221, and then be received by the second water receiving groove 122a of the lower water baffle 1221, thereby increasing the water receiving reliability of the second water receiving tray 122.

[0091] In some embodiments, the projection width d of the overlapping area is not less than 2.5 mm, that is, d ≥ 2.5 mm, for example, 2.5 mm, 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, 4.5 mm, 5 mm, 6 mm, 7 mm, etc., wherein the projection width of the overlapping area is perpendicular to the first direction.

[0092] In this way, the airflow entering from the air inlet 10a can smoothly pass through the air passage 122b, and the second water receiving groove 122a can also effectively collect condensed water, thereby reducing the probability of condensed water leakage.

[0093] Exemplarily, the upper and lower surfaces of the fourth baffle plate 12214 are inclined downward at a certain angle and can intersect with each other, so that condensed water dripping from the fourth baffle plate 12214 can be received by the first baffle plate 12211 below.

[0094] For some examples, see Figure 7 , the position of the top surface of the first baffle 12211 does not exceed the plane a where the third baffle 12213 is located.

[0095] In this way, when the airflow passes through the air passage 122b, the first baffle 12211 has less resistance to the airflow, which can increase the smoothness of the air intake in the air passage 122b, thereby increasing the operating reliability of the air conditioner 1.

[0096] For some examples, see Figure 6 The second water receiving tray 122 includes one or more reinforcing ribs 1223 , and the reinforcing ribs 1223 are connected to each water baffle 1221 .

[0097] The provision of the reinforcing ribs 1223 can increase the structural strength of each water baffle 1221 , improve the rigidity of the water baffle 1221 , and reduce the probability of the water baffle 1221 being deformed or damaged when falling.

[0098] The reinforcing rib 1223 has a ridge 12231 on the side facing the air inlet 10a. The ridge 12231 protrudes from the surface of the water retaining plate 1221 on the side facing the air inlet 10a. A part of the ridge 12231 is recessed away from the air inlet 10a to form a notch 12232.

[0099] Specifically, the recess 12232 can provide a platform for the electrical components of the air conditioner 1 to rest on when the air conditioner 1 is installed and maintained.

[0100] Exemplarily, the electrical components of the air conditioner 1 include an electric control assembly 14, which is disposed in the housing 10 and is disposed toward the windward surface 11a of the heat exchanger 11. The electric control assembly 14 can be used to realize the corresponding functions of the air conditioner 1. The electric control assembly 14 can include an electric control box and an electric control board assembly, and the electric control board assembly is placed in the electric control box. When the air conditioner 1 is produced or installed and maintained, the electric control box can be placed on the recess 12232 to install the electric control board assembly or perform patch cord operations, thereby increasing assembly convenience.

[0101] The specific structure of the first water receiving tray 121 is not limited.

[0102] For some examples, see Figure 5 The first water receiving tray 121 includes a first part 1211, a second part 1212 and a third part 1213, the first part 1211 extends along a first direction, the second part 1212 and the third part 1213 are connected to a side of the first part 1211 close to the air inlet 10a, and are arranged at intervals along the first direction, and the second water receiving tray 122 is arranged in the interval area between the second part 1212 and the third part 1213, wherein the first direction intersects with the height direction of the air conditioner 1.

[0103] Specifically, the first part 1211, the second part 1212 and the third part 1213 jointly define a first water receiving groove 121a, and the second water receiving pan 122 is arranged between the second part 1212 and the third part 1213. On the one hand, the extension length of the water receiving pan assembly 12 along the first direction can be reduced. On the other hand, it can also facilitate the first water receiving groove 121a to receive condensed water flowing down from the second water receiving groove 122a from different directions, thereby reducing the probability of condensed water leakage and increasing the water collection reliability of the water receiving pan assembly 12.

[0104] In some embodiments, the first end of the second water receiving trough 122a along the first direction is used to guide the liquid to the second part 1212, and the second end of the second water receiving trough 122a along the first direction is used to guide the liquid to the third part 1213, and the liquid in the second part 1212 flows into the third part 1213 through the first part 1211.

[0105] That is to say, the second part 1212 and the third part 1213 respectively receive the condensed water dripping from the two ends of the second water receiving groove 122a along the first direction, thereby increasing the collection efficiency of the condensed water received by the second water receiving groove 122a, reducing the water receiving pressure of the second water receiving groove 122a, and reducing the probability of condensed water leaking from the second water receiving groove 122a through the wind channel 122b, thereby increasing the water receiving reliability of the water receiving tray assembly 12. The second part 1212 receives the condensed water dripping along the inclined surface of the heat exchanger 11, and converges the condensed water received by itself and the condensed water from the second part 1212 to the third part 1213. In this way, the condensed water received by the first water receiving tray 121 and the second water receiving tray 122 is collected in the third part 1213, and the condensed water can be discharged to the outside by draining from the third part 1213.

[0106] For example, see Figure 5 Part of the structure of the third part 1213 is recessed downward to form a groove 1213c, and the water pump component is connected to the groove 1213c. The condensed water collected in the third part 1213 flows to the water pump component through the groove 1213c and is then discharged to the outside of the air conditioner 1.

[0107] For some examples, see Figure 2 and Figure 5 Part of the structure of the first part 1211 protrudes upward and forms a supporting structure 12111 , and one end of the heat exchanger 11 is supported on the supporting structure 12111 .

[0108] Specifically, one end of the heat exchanger 11 is supported on the supporting structure 12111, which can increase the installation stability of the heat exchanger 11. The structure of the first water receiving tray 121 is used to provide structural support for the heat exchanger 11 without the need for an additional supporting part 12121, thereby increasing the structural simplicity of the air conditioner 1. At the same time, it is also convenient for the first part 1211 to receive condensed water dripping along the inclined surface of the heat exchanger 11.

[0109] The heat exchanger 11 can be in face-to-face contact with the support structure 12111, so as to increase the contact area and increase the support stability.

[0110] For some examples, see Figure 2 and Figure 5 Part of the structure of the second portion 1212 protrudes upward and forms a supporting portion 12121 , and the heat exchanger 11 is supported on the supporting portion 12121 .

[0111] Specifically, one end of the heat exchanger 11 close to the second water receiving tray 122 is supported on the support portion 12121 , which can further increase the installation stability of the heat exchanger 11 and provide sufficient structural support for the heat exchanger 11 .

[0112] The heat exchanger 11 and the support portion 12121 may also be in surface contact to increase support reliability.

[0113] It is understandable that the first water receiving tray 121 may be provided with only the supporting structure 12111 or only the supporting portion 12121. Of course, it may also be provided with both the supporting structure 12111 and the supporting portion 12121. In this way, the heat exchanger 11 is supported on the supporting structure 12111 and the supporting portion 12121 respectively.

[0114] For some examples, see Figure 2 , Figure 3 and Figure 5 The first part 1211 has a side wall portion 12112 at one end away from the second water receiving tray 122, and a plurality of guide ribs 12113 are formed on the surface of the side wall portion 12112 facing the second water receiving tray 122. The plurality of guide ribs 12113 are arranged at intervals along the first direction, and the guide ribs 12113 extend along the height direction of the side wall portion 12112.

[0115] In this embodiment, the guide rib 12113 can increase the structural strength of the first water receiving tray 121, increase the rigidity of the first water receiving tray 121, and reduce the probability of deformation of the first water receiving tray 121 and affecting the working reliability. At the same time, the guide rib 12113 can also guide the airflow to facilitate the airflow to flow to the air outlet 10b.

[0116] Exemplarily, the air conditioner 1 includes a fan 13, which is arranged in the shell 10 and on the side of the heat exchanger 11 away from the air inlet 10a. When the air conditioner 1 is working, the fan 13 runs to generate negative pressure. Under the action of negative pressure, the airflow in the external environment contacts the heat exchanger 11 through the air inlet 10a and the air passage 122b. The airflow after heat exchange is discharged from the air outlet 10b through the fan 13 component. The guide rib 12113 can cooperate with the wind wheel to improve the airflow effect.

[0117] For some examples, see Figure 5 The third part 1213 is provided with a drain outlet 1213a, the water receiving tray assembly 12 includes a rubber plug 125, the drain outlet 1213a penetrates the bottom wall 121b of the third part 1213, and the rubber plug 125 is used to block the drain outlet 1213a.

[0118] Specifically, the drain port 1213a is used to drain the condensed water when the air conditioner 1 is repaired, thereby reducing the probability of water flowing out when the water receiving tray assembly 12 is disassembled and increasing the reliability of repair. The rubber plug 125 is used to block the drain port 1213a when the air conditioner 1 is in normal use, so that the first water receiving tray 121 can normally receive the condensed water.

[0119] For some examples, see Figure 5 An overflow port 1213 b is provided on a side wall of the third portion 1213 close to the second water receiving tray 122 .

[0120] Specifically, when an abnormality occurs in the normal drainage of the air conditioner 1, the overflow port 1213b can cause the condensed water collected in the third part 1213 to flow out from the overflow port 1213b and be directly discharged to the outside of the air conditioner 1, thereby reducing the risk of water in other parts of the water tray assembly 12 affecting the normal use of the air conditioner 1 and increasing the drainage reliability of the air conditioner 1.

[0121] For some examples, see Figure 5 and Fig. 9 The first water receiving tray 121 includes a plurality of protrusions 1214 disposed on the third portion 1213 , the bottom ends of the protrusions 1214 are connected to the bottom wall 121 b of the third portion 1213 , and at least some of the protrusions 1214 are spaced apart along the first direction.

[0122] Specifically, the convex column 1214 can stop impurities contained in the liquid flowing from the first part 1211 and the second part 1212 to the third part 1213, thereby facilitating the condensed water to be discharged to the outside of the air conditioner 1 through the water pump assembly, thereby increasing the drainage reliability.

[0123] For some examples, see Fig. 9 The protrusion 1214 extends from the bottom end to the top end, toward the direction close to the first part 1211.

[0124] That is, the protruding column 1214 extends obliquely toward the direction close to the first portion 1211 , thereby forming resistance to the flow of impurities, further reducing the probability of impurities flowing to the third portion 1213 and affecting drainage.

[0125] For some examples, see Figure 8 and Fig. 9 The first water receiving tray 121 includes a bottom wall 121b, and the water receiving tray assembly 12 includes a heat preservation structure 123, which is arranged on the bottom side of the bottom wall 121b.

[0126] Specifically, the heat-insulating structure 123 is used for heat preservation and reduction of energy loss. Furthermore, when the first water receiving tray 121 is filled with condensed water, the probability of water leakage can be reduced, thereby increasing the overall reliability of the water receiving tray assembly 12 .

[0127] The matching manner of the first water receiving tray 121 and the heat insulation structure 123 is not limited.

[0128] For some examples, see Figure 8 and Fig. 9 The local structure of the bottom wall 121b protrudes upward and forms a slot 121c on the bottom surface of the bottom wall 121b. The heat-insulating structure 123 is provided with a protruding structure 1231, and the protruding structure 1231 is located in the slot 121c.

[0129] In this embodiment, the first water receiving tray 121 is connected to the insulation structure 123 by the cooperation between the protruding structure 1231 and the slot 121c. When it is necessary to release the connection between the first water receiving tray 121 and the insulation structure 123 to clean or replace the first water receiving tray 121 or the insulation structure 123, it is only necessary to release the cooperation between the protruding structure 1231 and the slot 121c. This facilitates disassembly and assembly, thereby increasing the ease of use of the water receiving tray assembly 12.

[0130] For some examples, see Fig. 9 A plurality of protrusions 1232 are provided on a surface of the heat-insulating structure 123 facing the first water receiving tray 121 , and the heat-insulating structure 123 contacts the bottom surface of the bottom wall 121 b through the protrusions 1232 .

[0131] In this embodiment, the insulation structure 123 contacts the bottom surface of the bottom wall 121b through the protrusion 1232, reducing large-area surface-to-surface contact, which can reduce the thermal expansion and contraction sound that may be generated during the operation of the first water receiving tray 121 and improve the user experience of the air conditioner 1.

[0132] For some examples, see Figure 5 and Figure 6The water tray assembly 12 includes a mounting structure 124, which is connected to the top side of the second water tray 122. An end of the mounting structure 124 facing the air inlet 10a is formed with a mounting position 124a, and the mounting position 124a is used to install a disinfection lamp.

[0133] It is understandable that the disinfection lamp is used to kill bacteria, viruses and harmful microorganisms in the air conditioner 1, so as to provide clean and healthy airflow during the operation of the air conditioner 1. The disinfection lamp can be other equipment with sterilization function such as ultraviolet lamp, which is not limited here.

[0134] In this embodiment, the installation position 124a of the disinfection lamp is formed by using the installation structure 124, that is, the disinfection lamp is installed by using the water tray assembly 12, thereby reducing additional installation components.

[0135] For example, the mounting structure 124, the first water receiving tray 121 and the second water receiving tray 122 may be an integrated structure. Thus, the integrated structure can be used to receive the condensed water and provide an additional mounting position 124a for the disinfection lamp.

[0136] In some embodiments, the mounting structure 124 is provided with a plurality of ventilation holes 124 b , and the ventilation holes 124 b are communicated with the air inlet 10 a .

[0137] In other words, the mounting structure 124 can also allow the airflow from the air inlet 10a to pass through, thereby reducing wind resistance, increasing the air volume flowing to the heat exchanger 11, and improving heat exchange efficiency.
