Description

Technical Field

[0002] In related technologies, air conditioners include a casing, a heat exchanger, and a main drip tray. The heat exchanger and main drip tray are housed within the casing, with the main drip tray located at the bottom of the heat exchanger. To reduce the thickness of the air conditioner and meet the installation requirements of limited space, the heat exchanger is tilted without reducing its volume, thus minimizing its space occupation. However, during operation, some of the condensate on the heat exchanger surface flows along the tilted surface towards the main drip tray, while the remaining portion drips directly downwards under gravity and cannot be collected by the main drip tray. This drips onto the casing or enters the room through the air inlet of the casing, affecting the user experience. Summary of the Invention

[0049] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] This application provides an air conditioner 1, please refer to... Figures 1 to 9 It includes a shell 10, a heat exchanger 11, and a water receiving pan assembly 12.

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

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

[0053] Specifically, please refer to Figure 4 The windward side 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 comes into contact with the heat exchanger 11 through the windward side 11a and leaves the heat exchanger 11 through the leeward side 11b.

[0054] It is understood that the heat exchanger 11 is inclinedly disposed on the top side of the air inlet 10a, meaning that the heat exchanger 11 forms an angle with the horizontal direction, which refers to the direction parallel to the ground when the air conditioner 1 is in normal use. For example, the heat exchanger 11 is disposed inside the housing 10, and along the direction from the bottom to the top, the heat exchanger 11 extends inclinedly to the rear. Here, the rear side refers to the side of the air conditioner 1 that is away from the air outlet 10b when it is in normal use. The air outlet 10b is disposed on the front side, and the air inlet 10a is located on the rear side.

[0055] The tilted design of the heat exchanger 11 can reduce the thickness of the air conditioner 1 without reducing the volume of the heat exchanger 11, thus meeting the installation requirements in a limited space. In addition, it can also guide the airflow passing through the heat exchanger 11, allowing the airflow to be tilted towards the ground, expanding the range of airflow blowing towards the ground and improving the user experience.

[0056] It is understandable 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] Taking air conditioner 1 cooling an indoor space as an example, the heat exchanger 11 acts as an evaporator, exchanging heat with the airflow. Condensation will then form on the surface of the heat exchanger 11. Therefore, this embodiment of the application includes a drip tray assembly 12 to collect the condensation dripping from the surface of the heat exchanger 11.

[0058] Please see Figure 4 and Figure 5 The water receiving tray assembly 12 is disposed inside the housing 10. 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 disposed on the bottom side of the heat exchanger 11 and is provided with a first water receiving groove 121a. The second water receiving tray 122 is disposed between the windward side 11a and the air inlet 10a of the heat exchanger 11 and is provided with a second water receiving groove 122a and an air passage 122b for airflow.

[0059] It is understandable 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 into the heat exchanger 11 for heat exchange.

[0060] The first drip tray 121 and the second drip tray 122 together collect the condensate dripping from the surface of the heat exchanger 11. Specifically, when the heat exchanger 11 is working, part of the condensate flows down the inclined surface of the heat exchanger 11 and into the first drip tray 121 on the bottom side, where it is collected by the first drip trough 121a. The other part of the condensate drips down from the inclined surface of the heat exchanger 11 under the action of gravity and is collected by the second drip trough 122a of the second drip tray 122. In this way, almost all the condensate dripping from the heat exchanger 11 is collected by the first drip tray 121 and the second drip tray 122.

[0061] Understandably, in related technologies, heat exchangers are tilted, but air conditioners only have a drip tray on the bottom side of the heat exchanger. Part of the heat exchanger structure is exposed through the air inlet. Some of the condensate on the surface of the heat exchanger is easily dripped directly downwards under gravity and cannot be collected by the drip tray. As a result, it drips onto the casing or enters the room through the air inlet of the casing, affecting the user experience.

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

[0063] For example, the second drip tray 122 can also be inclined, and the inclination angle is close to the inclination angle of the heat exchanger 11, so that the second drip tray 122 can be set as close as possible to the heat exchanger 11 to collect the condensate generated by the heat exchanger 11. The setting of the second drip tray 122 can receive the condensate dripping directly downward from the heat exchanger 11. Therefore, the backward inclination angle of the heat exchanger 11 can be small. For example, the inclination angle α of the heat exchanger 11 is not greater than 45°, such as 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 drip tray 121 and the second drip tray 122 are integrally formed. That is, the first drip tray 121 and the second drip tray 122 are manufactured as a single piece, making the structure of the drip tray assembly 12 more stable, reducing the number of parts in the air conditioner 1, and reducing assembly steps. There are no connecting gaps between the first drip tray 121 and the second drip tray 122, reducing the probability of condensate leakage from the connection point between the first drip tray 121 and the second drip tray 122.

[0065] The air conditioner 1 provided in this embodiment uses a first drip tray 121 and a second drip tray 122 to collect the condensate generated by the heat exchanger 11, reducing the likelihood of condensate leaking outside the air conditioner 1 or affecting its electrical components, increasing the reliability of the air conditioner 1, meeting installation requirements in limited spaces, and achieving a slimmer design for the air conditioner 1. Furthermore, the integrated design of the first drip tray 121 and the second drip tray 122, while effectively collecting water, also reduces the number of parts and assembly steps in the air conditioner 1, further increasing the reliability of water collection.

[0066] The specific construction of the housing 10 is not limited. For example, please refer to [reference needed]. Figure 3 The housing 10 includes an upper shell 101 and a panel 102. The top of the upper shell 101 has a structure for fixed installation with the ceiling or 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 receiving tray are disposed within the space defined by the upper shell 101 and the panel 102. An air inlet 10a and an air outlet 10b are disposed on the panel 102. Specifically, the air inlet 10a and the air outlet 10b can be located at opposite ends of the panel 102 along the front-rear direction.

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

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

[0069] In other words, all parts of the windward side 11a of the heat exchanger 11 are within the projection area of ​​the water receiving pan assembly 12. No matter where the condensate falls from the heat exchanger 11, it can fall into the water receiving pan assembly 12 and be received by the first water receiving pan 121 and the second water receiving pan 122, reducing the probability of condensate dripping outside the water receiving pan assembly 12.

[0070] In some embodiments, please refer to Figure 5 The second water receiving tank 122a is connected to the first water receiving tank 121a; and the position of the second water receiving tank 122a is higher than that of the first water receiving tank 121a, so that the liquid in the second water receiving tank 122a flows into the first water receiving tank 121a.

[0071] In other words, the liquids in the first water receiving tank 121a and the second water receiving tank 122a are mutually circulated, and there is a height difference between the second water receiving tank 122a and the first water receiving tank 121a. The condensate received by the second water receiving tank 122a can flow to the first water receiving tank 121a under the action of gravity, thereby reducing the probability of condensate overflow and reducing the water receiving pressure of the second water receiving tank 122a, improving the collection efficiency of condensate, and the condensate can be discharged from the first water receiving tank 121a in a concentrated manner, increasing the reliability of drainage.

[0072] The first water collection tray 121a can drain the collected condensate. Exemplarily, the first water collection tray 121 is connected to a water pump component, which communicates with the first water collection tray 121a. The water pump component drains the condensate collected in the first water collection tray 121a to the outside of the air conditioner 1. In other embodiments, the first water collection tray 121a can also drain the condensate by gravity. Of course, the air conditioner 1 can also use a combination of the above two methods for drainage.

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

[0074] In some embodiments, please refer to Figure 5The second water receiving tray 122 includes multiple baffles 1221, which extend along a first direction and are arranged along a second direction. The interval between two adjacent baffles 1221 defines an air passage 122b. The side of the baffles 1221 facing the heat exchanger 11 forms a second water receiving trough 122a. The first direction, the second direction, and the height direction of the air conditioner 1 intersect each other.

[0075] The number of water baffles 1221 can be two, three, or more, and there is no limitation here. Multiple water baffles 1221 can define multiple second water receiving tanks 122a to increase water receiving efficiency and water receiving reliability.

[0076] Multiple baffles 1221 are spaced apart along a second direction, which may be parallel to the extension direction of the heat exchanger 11, so as to better catch the condensate dripping from the heat exchanger 11.

[0077] It is understood that the first direction can be perpendicular to the height direction of the air conditioner 1. For example, the first direction can be the left and right direction.

[0078] The baffle plate 1221 forms a second water receiving trough 122a on the side facing the heat exchanger 11. That is, the baffle plate 1221 itself defines the second water receiving trough 122a to collect the condensate generated by the heat exchanger 11.

[0079] The air passage 122b is defined by the interval between two adjacent baffles 1221. It is understood that in some embodiments, in the planar projection perpendicular to the height direction of the air conditioner 1, the projected portions of the two adjacent baffles 1221 overlap, and the overlapping area covers the air passage 122b. In this way, while allowing the air entering from the air inlet 10a to smoothly pass through the air passage 122b to enter the heat exchanger 11 for heat exchange, it also prevents condensate from leaking from the air passage 122b to the outside of the drip tray assembly 12.

[0080] The first direction can be the front-back direction or other directions; there are no restrictions here.

[0081] For example, the two ends of the baffle plate 1221 along the first direction are respectively connected to the first water receiving tray 121, so that each baffle plate 1221 is connected through the first water receiving tray 121, and the overall structure of the water receiving tray assembly 12 has high strength.

[0082] In some embodiments, please refer to Figure 5 Along the first direction, the bottom of the second water receiving tank 122a includes a first sub-segment 1221a and a second sub-segment 1221b. The first sub-segment 1221a extends downward at an angle away from the second sub-segment 1221b, and the second sub-segment 1221b extends downward at an angle away from the first sub-segment 1221a.

[0083] It should be noted that the bottom of the second water receiving tank 122a refers to the lowest part of the second water receiving tank 122a. The bottom of the second water receiving tank 122a along the first direction may consist only of the first sub-segment 1221a and the second sub-segment 1221b, that is, the end of the first sub-segment 1221a near the second sub-segment 1221b and the end of the second sub-segment 1221b near the first sub-segment 1221a are connected. Alternatively, the bottom of the second water receiving tank 122a may 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 spaced apart and connected by the other sub-segments.

[0084] The first sub-segment 1221a slopes downwards at the end furthest from the second sub-segment 1221b, and the second sub-segment 1221b extends downwards in a direction furthest from the first sub-segment 1221a. That is, the position of the first sub-segment 1221a furthest from the second sub-segment 1221b is lower than the position of the first sub-segment 1221a closest to the second sub-segment 1221b, and the position of the second sub-segment 1221b furthest from the first sub-segment 1221a is lower than the position of the second sub-segment 1221b closest to the first sub-segment 1221a. The bottom of the first water receiving tank 121a is roughly higher in the middle and lower at both ends. In this way, the condensate collected in the second water receiving tank 122a can flow rapidly along the inclined surfaces of the first sub-segment 1221a and the second sub-segment 1221b to the first water receiving tank 121a.

[0085] In some embodiments, please refer to 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 towards each other from the top to the bottom, together defining the second water receiving tank 122a. Specifically, the first baffle 12211 and the second baffle 12212 extend towards each other from the top to the bottom, forming a concave structure to define the space of the second water receiving tank 122a. Condensate dripping directly downward from the inclined surface of the heat exchanger 11 collects in the second water receiving tank 122a and then flows from the first water receiving tank 121a to the lower first water receiving tank 121a.

[0087] The third baffle 12213 extends upward at an angle from its connection with the second baffle 12212 toward the heat exchanger 11. Thus, when condensate dripping directly downward from the inclined surface of the heat exchanger 11 comes into contact with the third baffle 12213, the third baffle 12213 guides the condensate, allowing it to flow smoothly into the second water collection tank 122a for collection.

[0088] The fourth baffle 12214 extends downward from the connection point with the third baffle 12213. Thus, when condensate dripping directly downward from the inclined surface of the heat exchanger 11 comes into contact with the fourth baffle 12214, the fourth baffle 12214 can also act as a guide, allowing the condensate to flow to the second water receiving trough 122a of the water baffle 1221 located below, thereby completing the collection of condensate.

[0089] Among them, in the plane projection of any two adjacent water baffles 1221 in the direction perpendicular to the height 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 condensate received by the fourth baffle 12214 of the upper baffle 1221 can drip directly onto the first baffle 12211 of the lower baffle 1221, and then be received by the second water receiving trough 122a of the lower 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 region is not less than 2.5mm, that is, d≥2.5mm, for example, 2.5mm, 3mm, 3.2mm, 3.5mm, 3.8mm, 4mm, 4.5mm, 5mm, 6mm, 7mm, etc., wherein the projection width of the overlapping region is perpendicular to the first direction.

[0092] In this way, the airflow entering from the air inlet 10a can pass smoothly through the air passage 122b, while the second water collection tank 122a can effectively collect condensate, reducing the chance of condensate leakage.

[0093] For example, the upper and lower surfaces of the fourth baffle 12214 are inclined downward at a certain angle and can intersect, so that the condensate dripping from the fourth baffle 12214 can be caught by the first baffle 12211 below.

[0094] In some embodiments, please refer to Figure 7 The top surface of the first baffle 12211 does not exceed the plane a where the third baffle 12213 is located.

[0095] Thus, when the airflow passes through the air passage 122b, the first baffle 12211 provides less resistance to the airflow, which can increase the smoothness of the air intake of the air passage 122b, thereby increasing the operational reliability of the air conditioner 1.

[0096] In some embodiments, please refer to Figure 6 The second water receiving tray 122 includes one or more reinforcing ribs 1223, which are connected to each water baffle 1221.

[0097] The addition of reinforcing ribs 1223 can increase the structural strength of each baffle 1221, improve the rigidity of the baffle 1221, and reduce the probability of damage when the baffle 1221 deforms or falls.

[0098] Among them, the reinforcing rib 1223 has a spine 12231 on the side facing the air inlet 10a. The spine 12231 protrudes from the surface of the baffle 1221 on the side facing the air inlet 10a. A part of the spine 12231 is recessed in the direction away from the air inlet 10a to form a notch 12232.

[0099] Specifically, the notch 12232 can provide a platform for the installation and maintenance of the air conditioner 1, allowing the electrical components of the air conditioner 1 to rest on it.

[0100] For example, the electrical components of the air conditioner 1 include an electrical control assembly 14, which is disposed within the housing 10 and faces the airflow side 11a of the heat exchanger 11. The electrical control assembly 14 can be used to implement the corresponding functions of the air conditioner 1. The electrical control assembly 14 may include an electrical control box and an electrical control board assembly. The electrical control board assembly is placed inside the electrical control box. During the production, installation, or maintenance of the air conditioner 1, the electrical control box can be placed on the recess 12232 to facilitate the installation of the electrical control board assembly or the connection of wiring, thereby increasing the ease of assembly.

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

[0102] In some embodiments, please refer to 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 the side of the first part 1211 near the air inlet 10a and are arranged at intervals along the first direction. The second water receiving tray 122 is disposed in the interval area between the second part 1212 and the third part 1213. 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 together define the first water receiving tank 121a, and the second water receiving tray 122 is disposed between the second part 1212 and the third part 1213. On the one hand, this can reduce the extension length of the water receiving tray assembly 12 along the first direction. On the other hand, it can also facilitate the first water receiving tank 121a to receive the condensate flowing down from the second water receiving tank 122a from different directions, thereby reducing the probability of condensate leakage and increasing the water collection reliability of the water receiving tray assembly 12.

[0104] In some embodiments, the first end of the second water receiving tank 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 tank 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 via the first part 1211.

[0105] In other words, the second part 1212 and the third part 1213 respectively receive the condensate dripping from both ends of the second water receiving tank 122a along the first direction, thereby increasing the collection efficiency of the condensate received by the second water receiving tank 122a, reducing the water receiving pressure of the second water receiving tank 122a, and reducing the probability of condensate leaking from the second water receiving tank 122a through the air channel 122b, thereby increasing the water receiving reliability of the water receiving pan assembly 12. The second part 1212 receives the condensate dripping along the inclined surface of the heat exchanger 11, and the condensate it receives, as well as the condensate from the second part 1212, flows to the third part 1213. In this way, the condensate received by the first water receiving pan 121 and the second water receiving pan 122 gathers in the third part 1213, and the condensate can be discharged to the outside by draining from the third part 1213.

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

[0107] In some embodiments, please refer to Figure 2 and Figure 5 The first part 1211 has a portion of its structure protruding upwards to form a support structure 12111, and one end of the heat exchanger 11 is supported on the support structure 12111.

[0108] Specifically, one end of the heat exchanger 11 is supported on the support structure 12111, which can increase the installation stability of the heat exchanger 11. The structure of the first water receiving tray 121 provides structural support for the heat exchanger 11, eliminating the need for additional support parts 12121, thus increasing the structural simplicity of the air conditioner 1. It also facilitates the first part 1211 to receive condensate 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, thereby increasing the contact area and increasing the stability of the support.

[0110] In some embodiments, please refer to Figure 2 and Figure 5 The second part 1212 has a structure that protrudes upward and forms a support part 12121, on which the heat exchanger 11 is supported.

[0111] Specifically, the end of the heat exchanger 11 near the second water receiving pan 122 is supported on the support part 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 12121 can also be in surface contact to increase the reliability of the support.

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

[0114] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The first part 1211 has a side wall 12112 at one end away from the second water receiving tray 122. A plurality of guide ribs 12113 are formed on the surface of the side wall 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 12112.

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

[0116] For example, the air conditioner 1 includes a fan 13, which is disposed inside the housing 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 and generates negative pressure. Under the action of negative pressure, the airflow in the external environment comes into contact with 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 ribs 12113 can cooperate with the impeller to improve the airflow effect.

[0117] In some embodiments, please refer to 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. The rubber plug 125 is used to seal the drain outlet 1213a.

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

[0119] In some embodiments, please refer to Figure 5 An overflow port 1213b is provided on the side wall of the third part 1213 near the second water receiving tray 122.

[0120] Specifically, when the normal drainage of the air conditioner 1 is abnormal, the overflow port 1213b can cause the condensate collected in the third part 1213 to flow out from the overflow port 1213b and be discharged directly to the outside of the air conditioner 1, thereby reducing the leakage of water from other parts of the water tray assembly 12 that would affect the normal use of the air conditioner 1 and increasing the drainage reliability of the air conditioner 1.

[0121] In some embodiments, please refer to Figure 5 and Figure 9 The first water receiving tray 121 includes a plurality of protrusions 1214 disposed in the third part 1213. The bottom end of the protrusions 1214 is connected to the bottom wall 121b of the third part 1213. At least some of the protrusions 1214 are arranged at intervals along the first direction.

[0122] Specifically, the protrusion 1214 can stop impurities carried in the liquid flowing from the first part 1211 and the second part 1212 to the third part 1213, thereby facilitating the discharge of condensate to the outside of the air conditioner 1 via the water pump assembly and increasing drainage reliability.

[0123] In some embodiments, please refer to Figure 9 The protruding post 1214 extends from the bottom to the top in a direction close to the first part 1211.

[0124] In other words, the protrusion 1214 extends at an angle toward the first part 1211, thereby creating resistance to the flow of impurities and further reducing the probability of impurities flowing to the third part 1213 and affecting drainage.

[0125] In some embodiments, please refer to Figure 8 and Figure 9 The first water receiving tray 121 includes a bottom wall 121b, and the water receiving tray assembly 12 includes a heat insulation structure 123, which is disposed on the bottom side of the bottom wall 121b.

[0126] Specifically, the insulation structure 123 is used for heat preservation to reduce energy loss. Furthermore, when the first drip tray 121 collects condensate, it can also reduce the chance of leakage, thus increasing the overall reliability of the drip tray assembly 12.

[0127] The way the first water receiving tray 121 is matched with the insulation structure 123 is not limited.

[0128] In some embodiments, please refer to Figure 8 and Figure 9 The partial structure of the bottom wall 121b protrudes upward and forms a groove 121c on the bottom surface of the bottom wall 121b. The heat insulation structure 123 is provided with a protruding structure 1231, which is located in the groove 121c.

[0129] In this embodiment, the first water receiving tray 121 and the heat insulation structure 123 are connected by the cooperation of the protruding structure 1231 and the slot 121c. When it is necessary to disconnect the first water receiving tray 121 and the heat insulation structure 123 to clean or replace the first water receiving tray 121 or the heat insulation structure 123, it is only necessary to disconnect the cooperation of the protruding structure 1231 and the slot 121c. The disassembly and assembly are convenient, which increases the ease of use of the water receiving tray assembly 12.

[0130] In some embodiments, please refer to Figure 9 The surface of the insulation structure 123 facing the first water receiving tray 121 is provided with a plurality of protrusions 1232, and the insulation structure 123 contacts the bottom surface of the bottom wall 121b through the protrusions 1232.

[0131] In this embodiment, the heat insulation structure 123 contacts the bottom surface of the bottom wall 121b through the protrusion 1232, reducing the large area of ​​surface-to-surface contact, which can reduce the thermal expansion and contraction noise 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] In some embodiments, please refer to Figure 5 and Figure 6The water receiving tray assembly 12 includes a mounting structure 124, which is connected to the top side of the second water receiving tray 122. The mounting structure 124 has a mounting position 124a at one end facing the air inlet 10a, which is used to install a disinfection lamp.

[0133] Understandably, 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 devices with sterilization functions, such as ultraviolet lamps, and there are no restrictions here.

[0134] In this embodiment, the mounting structure 124 forms the mounting position 124a of the disinfection lamp, that is, the disinfection lamp is installed using the water receiving tray assembly 12, reducing additional mounting components.

[0135] For example, the mounting structure 124, the first drip tray 121, and the second drip tray 122 can be an integral structure. In this way, a single integral structure can both collect condensate 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 openings 124b, which are connected to the air inlet 10a.

[0137] In other words, the installation structure 124 also allows the airflow of the air inlet 10a to pass through, reducing wind resistance, increasing the airflow to the heat exchanger 11, and improving heat exchange efficiency.
