Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner. Background Art

[0002] The indoor unit of an air conditioner usually has two installation methods: floor-mounted and ceiling-mounted, which provide more choices for the installation of the air conditioner, enabling it to select a suitable installation method according to different installation positions and installation condition limitations. Therefore, it is more flexible and convenient to use and can better meet the requirements of users.

[0003] The indoor unit of an air conditioner includes a housing and an indoor heat exchanger, a heat exchange fan, and a water receiving tray disposed inside the housing. The housing includes at least an air inlet and an air outlet of the air conditioner that communicate with the interior. The indoor air flow is introduced into the interior of the housing through the air inlet of the air conditioner under the action of the heat exchange fan, and flows into the room through the air outlet of the air conditioner after heat exchange by the indoor heat exchanger. The water receiving tray is disposed below the indoor heat exchanger to collect the condensed water generated by the indoor heat exchanger during floor-mounted and ceiling-mounted installations of the indoor unit.

[0004] In order to achieve the inclined installation of the direct-discharge indoor heat exchanger, a positioning surface that abuts against the first end face of the indoor heat exchanger is usually provided on the water receiving tray. In the related art, in the cross-section of the water receiving tray, the size of the positioning surface is small, so that the contact length between the inclined surface of the indoor heat exchanger part and the positioning surface is relatively short, which easily causes the indoor heat exchanger to be placed in place manually, and then causes the inclined surface of the indoor heat exchanger not to fit the positioning surface, resulting in gaps and air leakage due to poor sealing.

[0005] In addition, sealing plates are usually provided at both ends of the indoor heat exchanger to prevent the air that has not been heat-exchanged by the indoor heat exchanger from flowing out. In the related art, the straight edge of the sealing plate is directly attached to the water receiving tray, forming a line contact. Due to the manufacturing tolerances of parts and the operation errors of workers, there are often problems such as loose line contact, flashing seams, and air leakage due to poor sealing, which affect the user experience. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems in the related art to some extent. For this reason,

[0105] The heat exchange fan 3 is arranged inside the second inner cavity 193 and is used to drive the indoor air outside the housing 1 to enter the straight air duct inside the housing 1 through the air inlet. The heat exchange fan 3 drives the air in the straight air duct to flow along the direction from the air conditioner air inlet 13 to the air conditioner air outlet 14.

[0106] Continue to refer to Figure 5 , when the air conditioner indoor unit 100 is installed in a seated manner, the heat exchange fan 3 is arranged below the indoor heat exchanger 2. In the air flow direction inside the housing 1, the heat exchange fan 3 is located upstream relative to the indoor heat exchanger 2.

[0107] When the air conditioner indoor unit 100 operates, under the drive of the heat exchange fan 3, the indoor air enters the straight air duct through the air conditioner air inlet 13. The indoor air in the straight air duct flows through the indoor heat exchanger 2 for heat exchange. The heat exchange air flow after heat exchange is discharged outside the room through the air conditioner air outlet 14, so that the air conditioner cools and heats, plays a role in adjusting the indoor temperature, and reaches the comfortable temperature of the user.

[0116] The indoor heat exchanger 2 can include a plurality of heat exchange tubes. The plurality of heat exchange tubes are inserted into the heat exchange main body 21 and are in a bent and coiled shape.

[0117] A refrigerant can flow in the heat exchange tubes. The flow of the refrigerant in the heat exchange tubes can bring indoor heat to the outside, so as to achieve the purpose of heat exchange between the indoor heat exchanger 2 and the indoor air.

[0118] The end of the heat exchange tube is configured as a bent portion, that is, the heat exchange tube has a bent end 22. The bent portion is a U-shaped bent structure, so that the heat exchange tube can be bent and arranged in the limited space inside the casing 1 to arrange a longer heat exchange tube. This can increase the contact area between the heat exchange tube and the indoor air, thereby improving the heat exchange capacity of the indoor heat exchanger 2.

[0119] The air conditioner outdoor unit can include an outdoor casing. An outdoor heat exchange air duct can be provided inside the outdoor casing.

[0120] The outdoor housing may include an outdoor air inlet. The outdoor air inlet may communicate with an outdoor heat exchange air duct. The outdoor air inlet may be used to introduce outdoor air into the outdoor heat exchange air duct.

[0121] The outdoor housing may include an outdoor air outlet. The outdoor air outlet may communicate with the outdoor heat exchange air duct. The outdoor air outlet may be used to lead the air in the outdoor heat exchange air duct out of the outdoor heat exchange air duct.

[0122] The outdoor unit of the air conditioner may include an outdoor heat exchanger. The outdoor heat exchanger may be disposed in the outdoor heat exchange air duct.

[0123] The outdoor unit of the air conditioner may include an outdoor fan. The outdoor fan may be disposed in the outdoor heat exchange air duct.

[0124] The rotation of the outdoor fan causes outdoor air to enter the heat exchange air duct through the outdoor air inlet and exchange heat with the outdoor heat exchanger, and the heat-exchanged outdoor air flows out of the outdoor heat exchange air duct through the outdoor air outlet.

[0125] The air conditioner may include a compressor. The compressor is disposed in the outdoor heat exchange air duct.

[0126] The air conditioner may include a throttling device. The throttling device is used for throttling. The throttling device may be provided in the indoor unit of the air conditioner or the outdoor unit of the air conditioner.

[0127] The air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes, involving compression, condensation, expansion and evaporation, and supplying refrigerant to the air that has been conditioned and heat-exchanged.

[0128] The compressor compresses the refrigerant gas in the low-temperature and low-pressure state and discharges the refrigerant gas in the high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0129] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0130] The throttling device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0131] The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in the low-temperature and low-pressure state to the compressor.

[0132] The evaporator may achieve the refrigeration effect by using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. During the whole cycle, the air conditioner may adjust the temperature of the indoor space.

[0133] In the indoor heat exchanger and the outdoor heat exchanger, one of them is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0134] In some embodiments of the present application, referring to Figure 4 , Figure 8 , the air conditioner indoor unit 100 may include a water receiving tray 4.

[0135] Referring to Figure 5 , the water receiving tray 4 is arranged in the first inner cavity 192, and the water receiving tray 4 is located below the indoor heat exchanger 2, and is used for receiving the condensed water dripping from the indoor heat exchanger 2 in the cooling mode.

[0136] Among them, when the air conditioner indoor unit 100 is hoisted, the projection of the indoor heat exchanger 2 in the vertical direction is located in the water receiving tray 4, so as to ensure that the water receiving tray 4 can collect most of the condensed water generated by the indoor heat exchanger 2, avoid damage to the electrical components of the air conditioner indoor unit 100 caused by the condensed water, and also avoid the condensed water seeping out of the housing 1 and dripping, affecting the user experience.

[0137] Furthermore, in order to drain the condensed water contained in the water receiving tray 4 in time, the air conditioner indoor unit 100 may include a drain port 41.

[0138] In the related art, the drain port 41 is usually arranged at the bottom end of the water receiving tray 4 when the air conditioner indoor unit 100 is installed in a sitting position, and the drain pipe 52 is usually arranged on the left side of the indoor heat exchanger 2 when the air conditioner indoor unit 100 is installed in a sitting position. The indoor heat exchanger 2 cannot move to the left, otherwise the drain port 41 will be blocked, and it is impossible to ensure the smooth outflow of the condensed water. At the same time, the drain pipe 52 is located below the air inlet grille, which will block the air inlet area of the left volute 31. At the same rotational speed of the driving motor, the air intake volume of the air conditioner indoor unit 100 will become smaller, and at the same time, the user can directly see the drain pipe 52, and the appearance is not beautiful.

[0139] In the related art, the space at the left U-tube position of the indoor heat exchanger 2 is relatively large, mainly limited by the position of the bottom drain port 41. This part of the space affects the size of the housing 1 of the whole machine, resulting in a relatively large length direction of the housing 1, which is not conducive to the miniaturization of the machine body and increases the sea transportation container cost.

[0140] In order to solve the above technical problems, in some embodiments of the present application, the drain port 41 is opened on the side wall of one end in the length direction of the water receiving tray 4.

[0141] By arranging the drain opening 41 on the side wall in the length direction of the water receiving tray 4, on the one hand, the position of the indoor heat exchanger 2 can be moved relative to the drain opening 41 when it is arranged at the bottom of the drain tray, so that the installation space on the side of the drain opening 41 of the indoor heat exchanger 2 becomes smaller. Correspondingly, the size of the water receiving tray 4 can be reduced accordingly, and then the length of the entire housing 1 can be reduced, which can increase the quantity of products packed in a sea container and reduce the transportation cost. On the other hand, one end of the indoor heat exchanger 2 can increase in size towards the drain opening 41. Under the condition that the size of the housing 1 remains unchanged, the heat exchange area can be increased.

[0142] As Figure 8 shown, in this embodiment, the drain opening 41 is opened at the left end of the water receiving tray 4 when the air conditioner indoor unit 100 is installed.

[0143] In this embodiment, the position of the drain opening 41 is adjusted from the lower side in the prior art to the left side, so that the position of the indoor heat exchanger 2 is not limited by the position of the drain opening 41 and can move to the left. When the indoor heat exchanger 2 moves to the left, it does not block the drain opening 41, and at the same time, the space on the left side of the indoor heat exchanger 2 is reduced, reducing the overall size of the air conditioner indoor unit. While meeting the miniaturization of the housing 1 of the air conditioner indoor unit, the overall cost is reduced. In addition, the smaller overall size makes the overall packaging size smaller, increases the number of units installed in a sea container, reduces the sea freight, and improves the market competitiveness.

[0144] Define the end plate sleeved outside the bent end 22 among the two end plates as the first end plate 23, and define the other end plate as the second end plate 24. Among them, the drain opening 41 is arranged close to the first end plate 23.

[0145] Refer to Figure 7 , a plurality of avoidance holes 231 are arranged on the first end plate 23, and the bent end 22 of the heat exchange tube penetrates through the avoidance holes 231. Among them, the avoidance holes 231 can be sleeved on the bent end 22, so as to provide good protection for the indoor heat exchanger 2, improve the stability of the indoor heat exchanger 2 and extend its service life.

[0146] Among them, the drain opening 41 is arranged on the side wall at one end in the length direction of the water receiving tray 4, and the bent end 22 of the heat exchange tube of the indoor heat exchanger 2 can move towards the drain opening 41, reducing the installation space of the indoor heat exchanger 2. The structure of the bent end 22 of the heat exchange tube is simple. During the movement process, only the safety distance between the heat exchange tube and the side plate 17 needs to be considered, which is convenient for the overall movement of the indoor heat exchanger 2 and improves the movement convenience.

[0147] In some embodiments of the present application, the air conditioner indoor unit 100 may include a drainage assembly 5.

[0148] Refer to Figure 9, the water inlet end of the drainage component 5 is connected to the drain port 41, and the drainage end of the drainage component 5 extends to the outside of the housing 1 for draining the condensed water in the water receiving tray 4 to the outside of the housing 1.

[0149] The two side covers are respectively a first side cover 181 and a second side cover 182. Define one of the two side covers close to the drain port 41 as the first side cover 181, and the drainage component 5 is arranged inside the first side cover 181.

[0150] Specifically, the drainage component 5 is arranged inside the first side cover 181, and the user cannot directly see the drainage component 5, which improves the appearance beauty of the whole machine.

[0151] Reference Figure 9 、 Figure 10 , the first side cover 181 is connected to one of its side plates 17, and a first accommodation space is formed between the first side cover 181 and its side plate 17, and the drainage component 5 is arranged in the first accommodation space.

[0152] The first accommodation space is located outside the straight air duct. That is to say, the drainage component 5 does not occupy the position of the second inner cavity 193, avoiding affecting the air intake volume of the air conditioner indoor unit 100.

[0153] Furthermore, reference Figure 9 , an avoidance part 6 is arranged on the first side cover 181, and the drainage component 5 passes through the avoidance part 6 and extends to the outside of the housing 1.

[0154] Among them, the avoidance part 6 can be opened on the first side wall 1811 of the first side cover 181. The first side wall 1811 forms the bottom wall of the first side cover 181 when the air conditioner indoor unit 100 is installed in a seated position.

[0155] In some embodiments of the present application, in order to improve the versatility when the air conditioner indoor unit 100 is installed in a seated position, the avoidance part 6 can be opened on the first side wall 1811 and the second side wall 1812 of the first side cover 181.

[0156] Reference Figure 9 、 Figure 11 , the first side wall 1811 forms the bottom wall of the first side cover 181 when the air conditioner indoor unit 100 is installed in a seated position, and the second side wall 1812 forms the rear side wall of the first side cover 181 when the air conditioner indoor unit 100 is installed in a seated position.

[0157] When the air conditioner indoor unit 100 is installed in a seated position, the drainage end of the drainage component 5 can pass through one of the avoidance parts 6 and extend to the outside of the housing 1. That is to say, when installed in a seated position, it can be selected according to needs that the drainage component 5 extends out from the bottom end of the first side cover 181 or from the rear side of the first side cover 181 for drainage. Among them, the drainage component 5 extends out through the avoidance part 6 at the rear side of the first side cover 181 for drainage, which does not affect the appearance of the whole machine and is beneficial to improving the appearance beauty of the whole machine.

[0158] In some embodiments of the present application, the drainage assembly 5 is rotatably arranged relative to the drainage port 41, facilitating the adjustment of the position of the drainage assembly 5. When the air conditioner indoor unit 100 is installed in a sitting position, the drainage can be selected to extend from the bottom or the rear side by rotating the drainage assembly 5 according to the actual installation scenario.

[0159] In some embodiments of the present application, the drainage assembly 5 may include a water pipe elbow 51. One end of the water pipe elbow 51 is detachably connected to the drainage port 41. Among them, the water pipe elbow 51 is in an L shape.

[0160] The drainage assembly 5 may include a drainage pipe 52. One end of the drainage pipe 52 is connected to the end of the water pipe elbow 51 away from the drainage port 41, and the drainage pipe 52 passes through the avoidance portion 6 and extends to the outside of the housing 1 to drain the condensed water in the water receiving tray 4 to the outside of the housing 1. Among them, the water pipe elbow 51 is connected between the drainage port 41 and the drainage pipe 52 to transfer the flow direction.

[0161] In this embodiment, the water pipe elbow 51 can be installed by rotating 90° at the drainage port 41, which can change the state of the drainage pipe 52 from passing through one avoidance portion 6 to passing through another avoidance portion 6.

[0162] In some embodiments of the present application, the air conditioner indoor unit 100 may include a pipeline cover 7, and the pipeline cover 7 is sleeved outside the drainage assembly 5. Among them, the pipeline cover 7 is connected to the first side cover 181 to shield the avoidance portion 6.

[0163] Reference Figure 10 , which shows the pipeline cover 7 shielding the avoidance portion 6 on the bottom wall of the first side cover 181. By providing the pipeline cover 7 to seal the first side cover 181, users will not observe the drainage assembly 5 inside the first side cover 181, further improving the overall aesthetics of the machine.

[0164] In some embodiments of the present application, reference Figure 13 , the water receiving tray 4 may include a first water receiving portion 42. The first water receiving portion 42 is located below the indoor heat exchanger 2 when the air conditioner indoor unit 100 is hoisted.

[0165] The water receiving tray 4 may include a second water receiving portion 43. The second water receiving portion 43 is located below the indoor heat exchanger 2 when the air conditioner indoor unit 100 is installed in a sitting position.

[0166] The first water receiving portion 42 and the second water receiving portion 43 are connected at an angle. Among them, one end of the first water receiving portion 42 is connected to one end of the second water receiving portion 43.

[0167] The water receiving tray 4 may include two side water retaining parts 44. The two side water retaining parts 44 are arranged around both ends of the first water receiving part 42 and the second water receiving part 43 in the length direction of the housing 1, so that the water receiving tray 4 forms a water receiving cavity for collecting the condensed water of the indoor heat exchanger 2. Wherein, the water receiving cavity has an open upper end structure, which is convenient for collecting condensed water.

[0168] It should be noted that the projection of the indoor heat exchanger 2 in the vertical direction is located in the water receiving cavity, so as to ensure that the water receiving tray 4 can collect most of the condensed water generated by the indoor heat exchanger 2.

[0169] Reference Figure 13 , the drain port 41 is arranged at a position of the side water retaining part 44 close to the second water receiving part 43. This setting enables the condensed water in the first water receiving part 42 and the second water receiving part 43 to flow out from the drain port 41.

[0170] In some embodiments of the present application, both ends of the water receiving tray 4 in the length direction are detachably connected to the two side plates 17.

[0171] In the related art, the water receiving tray 4 is installed by screws and lacks a positioning structure during installation. When workers install the water receiving tray 4, they need to hold the water receiving tray 4 by hand first, find the installation position of the screw holes, and then drive the screws. The installation process requires manual alignment of the installation position, resulting in low installation efficiency.

[0172] To solve the above technical problems, in this embodiment, a positioning structure is used for positioning and installing the water receiving tray 4.

[0173] Specifically, referring to Figure 14 , both ends of the water receiving tray 4 in the length direction are convexly provided with limiting parts 46, and the side plates 17 are provided with notches 173 adapted to be connected with the limiting parts 46. The limiting parts 46 are adapted to be connected with the notches 173 to realize the installation positioning of the water receiving tray 4.

[0174] In this embodiment, there are two limiting parts 46, and there are also two notches 173. The two limiting parts 46 are adapted to be connected with the two notches 173 to realize the four-point positioning of the water receiving tray 4.

[0175] Furthermore, both ends of the water receiving tray 4 in the length direction are convexly provided with connecting parts 47, and the side plates 17 are provided with installation parts 174 corresponding to the connecting parts 47. The connecting parts 47 and the installation parts 174 are fixedly connected by first fasteners, so that the water receiving tray 4 is detachably connected to the side plates 17. Wherein, the first fastener can be a screw, and both the connecting parts 47 and the installation parts 174 are screw through holes.

[0176] In this embodiment, when the worker installs the water receiving tray 4, the two limiting parts 46 on one side are installed first, and then the two limiting parts 46 on the other side are installed. In this way, the four limiting parts 46 of the water receiving tray 4 are all adaptively connected to the four notches 173, realizing four-point positioning, ensuring the accurate left, right, front and back positions of the water receiving tray 4, making the position of the water receiving tray 4 not deviate, and eliminating the need for manual adjustment by the worker. After positioning, the connecting part 47 and the installation part 174 are correspondingly arranged, and can be directly fixed with fasteners at the position of the installation part 174, improving the assembly efficiency.

[0177] In the related art, the water receiving tray 4 is connected to the side plate 17 and the air inlet panel 12 in a three-layer structure. Among them, both ends of the water receiving tray 4 overlap on the side plate 17, and the air inlet panel 12 is then placed on the water receiving tray 4. Since there is only one screw fixing on each side of the connection between the water receiving tray 4 and the side plate 17, it is extremely easy to cause the screw through holes on the water receiving tray 4 where the air inlet panel 12 and the side plate 17 are connected and fixed to be offset. The screw holes of the air inlet panel 12 and the side plate 17 are concentric, but the screw through holes of the water receiving tray 4 sandwiched in the middle are not concentric with the screw holes of the air inlet panel 12, and it is impossible to install or the worker needs to manually correct the position and adjust it to the concentric position before installing the screws.

[0178] In addition, the water receiving tray 4 is made of plastic material. For the screw connection of the three-layer structure, the plastic water receiving tray 4 is sandwiched between two layers of sheet metal of the side plate 17 and the air inlet panel 12. When using a larger force to install the electric screw, the plastic water receiving tray 4 sometimes will be extruded with cracks, which is extremely likely to cause quality accidents.

[0179] In some embodiments of the present application, a plurality of convex parts 45 are provided at both ends of the water receiving tray 4, and the plurality of convex parts 45 are arranged at intervals along the first direction. In this embodiment, three convex parts 45 are configured.

[0180] Reference Figure 14 、 19 , the three convex parts 45 protrude towards the direction away from the center of the water receiving tray 4 relative to the end face of the water receiving tray 4. Two limiting parts 46 and the connecting part 47 are respectively arranged on the three convex parts 45 in one-to-one correspondence.

[0181] In this embodiment, the three convex parts 45 are arranged on the side water retaining part 44.

[0182] Reference Figure 15 , a second flanging 171 is provided on the side plate 17, and a recessed part 172 adapted to the three convex parts 45 is formed on the second flanging 171. Among them, there is a gap between the recessed part 172 and the air inlet panel 12, and two notches 173 and the installation part 174 are respectively opened on the three recessed parts 172 in one-to-one correspondence.

[0183] During assembly, the three convex portions 45 on the water receiving tray 4 are respectively inserted into the three concave portions 172, and the limiting portion 46 is clamped and matched with the notch 173, realizing the four-point positioning of the water receiving tray 4, ensuring that the installation position is fixed, eliminating the need for manual adjustment, and improving the assembly efficiency.

[0184] There is a gap between the concave portion 172 and the air inlet panel 12, enabling the water receiving tray 4 and the side plate 17 to be fixedly connected separately by the first fasteners, without the need for the first fasteners to pass through the fastener through holes of the air inlet panel 12, improving the installation speed, and thus increasing the production efficiency.

[0185] Furthermore, referring to Figure 16 、 Figure 17 , at both ends in the length direction of the air inlet panel 12, first connection holes 121 are provided, and second connection holes 175 are provided on the second flanging 171.

[0186] Among them, when the limiting portion 46 is adaptively connected to the notch 173, the first connection holes 121 and the second connection holes 175 are correspondingly arranged and fixedly connected by the second fasteners.

[0187] Referring to Figure 18 , the three convex portions 45 are located between the air inlet panel 12 and the side plate 17. The air inlet panel 12 and the side plate 17 are fixedly connected separately by the second fasteners, without the need for the second fasteners to pass through the fastener through holes (connection portion 47) of the water receiving tray 4, improving the installation speed, and thus increasing the production efficiency.

[0188] In this embodiment, by providing four limiting portions 46 on the water receiving tray 45, during assembly, it is directly clamped into the notch 173 on the concave portion 172 of the side plate 17 to realize position positioning. The water receiving tray 4 and the side plate 17 are fixedly connected separately by the first fasteners, and the air inlet panel 12 and the side plate 17 are fixedly connected separately by the second fasteners. There is no need for the second fasteners to pass through the connection portion 47 of the water receiving tray 4, and there will be no situation where the first connection holes 121 of the air inlet panel 12 and the second connection holes 175 are not concentric and the second fasteners cannot be assembled due to the position deviation of the water receiving tray 4. The existing three-layer structure connection is changed to a two-layer structure connection, improving the installation speed, and thus increasing the production efficiency.

[0189] Referring to Figure 19 , at both ends in the length direction of the air inlet panel 12, third flangings 122 are provided. Among them, the first connection holes 121 are opened on the third flangings 122.

[0190] In some embodiments of the present application, the limiting portion 46 is clamped in the notch 173. Among them, a wire routing portion 461 is formed inside the limiting portion 46. The setting of the wire routing portion 461 is for routing wires and can cooperate with the side-end wire routing of the air conditioner indoor unit 100.

[0191] In some embodiments of the present application, in order to achieve the installation and positioning of the indoor heat exchanger 2, a positioning surface 48 is formed on the water receiving tray 4.

[0192] Reference Figure 21 , the positioning surface 48 is formed on the first water receiving portion 42. The positioning surface 48 abuts against the first end face of the indoor heat exchanger 2. Among them, the positioning surface 48 is inclined, which can adapt to the inclined installation of the direct-discharge type indoor heat exchanger 2.

[0193] The first end face of the indoor heat exchanger 2 abuts against the positioning surface 48, so that the water receiving tray 4 can support and position the indoor heat exchanger 2.

[0194] In the related art, in the cross-section of the water receiving tray 4 perpendicular to the length direction of the housing 1, the size of the positioning surface 48 is small, so that when the worker installs the indoor heat exchanger 2, the contact length between the first end face at the bottom of the indoor heat exchanger 2 and the positioning surface 48 is relatively short, which easily leads to the improper placement of the indoor heat exchanger 2 by the worker. Furthermore, there will be a gap between the first end face of the indoor heat exchanger 2 and the positioning surface 48, and they will not fit tightly, resulting in the problem of air leakage due to poor sealing.

[0195] To solve the above technical problems, in some embodiments of the present application, the air conditioner indoor unit 100 may include a plurality of guiding members 8.

[0196] Reference Figure 21 , the guiding members 8 are arranged between the positioning surface 48 and the second water receiving portion 43. Among them, the plurality of guiding members 8 are spaced along the length direction of the housing 1.

[0197] A guiding surface 81 is formed on the guiding member 8. In the cross-section of the water receiving tray 4 perpendicular to the length direction of the housing 1, the guiding surface 81 is located on the extension line of the positioning surface 48. Among them, the guiding surface 81 abuts against the first end face of the indoor heat exchanger 2. Reference Figure 21 , in the cross-section of the water receiving tray 4 perpendicular to the length direction of the housing 1, the end of the guiding surface 81 away from the bottom positioning surface 48 extends to the outside of the first end face. That is to say, the top of the guiding surface 81 extends beyond the top of the first end face of the indoor heat exchanger 2 that abuts against it.

[0198] For the air conditioner indoor unit 100 provided in this embodiment, by adding a plurality of guiding members 8 at the position of the positioning surface 48, the positioning surface 48 has an extended section, increasing the contact area of the first end face of the indoor heat exchanger 2, avoiding the problem of improper placement of the indoor heat exchanger 2 caused by the relatively short contact length between the first end face of the indoor heat exchanger 2 and the positioning surface 48 in the related art, and avoiding the problem of air leakage due to the non-fitting gap between the first end face of the indoor heat exchanger 2 and the positioning surface 48.

[0199] In some embodiments of the present application, reference Figure 24, a plurality of air passing holes 82 are provided on the guiding surface 81. Among them, the plurality of air passing holes 82 penetrate through the guiding surface 81.

[0200] For the air conditioner indoor unit 100 provided in this embodiment, by providing the air passing holes 82, the air intake of the indoor heat exchanger 2 is increased, the influence of the guiding member 8 on the air intake volume of the indoor heat exchanger 2 is avoided, which is beneficial to improving the heat exchange efficiency.

[0201] In some embodiments of the present application, the guiding member 8 has a first end that abuts against the second water receiving part 43, and a part of the first end is recessed towards the direction close to the guiding surface 81 to form a water passing part 83.

[0202] Reference Figure 22 , in this embodiment, the water passing part 83 can be a semicircular through hole. Of course, in some other embodiments, the water passing part 83 can be a through hole of other shapes.

[0203] By providing the water passing part 83, when the whole machine is installed, the condensed water in the second water receiving part 43 can flow through the water passing part 83, avoiding the guiding member 8 from obstructing the flow direction of the condensed water. The condensed water that can flow through the water passing part 83 flows to the drain port 41 and is drained to the outside of the whole machine through the drainage assembly 5.

[0204] In some embodiments of the present application, reference Figure 25 , the air conditioner indoor unit 100 may include two sealing plates 9. Sealing plates 9 are detachably connected between the two ends in the length direction of the indoor heat exchanger 2 and the two side plates 17 to ensure a safe distance between the heat exchange tubes of the indoor heat exchanger 2 and the side plates 17. By providing the sealing plates 9, the air that has not passed through the heat exchange of the indoor heat exchanger 2 can be prevented from flowing out.

[0205] The two sealing plates 9 are respectively detachably connected between the end plates at both ends of the indoor heat exchanger 2 and the two side plates 17. Define the sealing plate 9 close to the drain port 41 among the two sealing plates 9 as the first sealing plate, and the other sealing plate 9 as the second sealing plate.

[0206] Among them, when the drain port 41 is provided at one end in the length direction of the water receiving tray 4, the whole indoor heat exchanger 2 can move towards the direction of the drain port 41, reducing the installation space of the indoor heat exchanger 2, so that the connection width of the first sealing plate will also become smaller, which is beneficial to reducing the material cost.

[0207] In this embodiment, through actual calculation, the connection width of the first sealing plate can be reduced by 28 mm, which can directly reduce the length of the box body of the indoor unit by 28 mm.

[0208] In the related art, when the indoor heat exchanger 2 is assembled, one end in the length direction of the sealing plate 9 directly abuts against the first water receiving part 42, and the two form a line contact. Due to the manufacturing tolerances of parts and the operation errors of assembly workers, there are often problems such as loose line contact, flash seams, and air leakage due to poor sealing.

[0209] To solve the above technical problems, referring to Figure 26 , in this embodiment, a first flanging 91 is provided on the sealing plate 9.

[0210] Referring to Figure 27 , a butting rib 49 is provided on the first water receiving part 42, and a sponge layer is provided on the butting rib 49.

[0211] Referring to Figure 28 , when the indoor heat exchanger 2 is assembled, the first flanging 91 presses the sponge layer to abut against the butting rib 49, effectively avoiding problems such as flash seams and air leakage due to poor sealing.

[0212] In this embodiment, the butting rib 49 can be provided on the second sealing plate. The connection width of the second sealing plate is greater than that of the first sealing plate, so the problem of poor sealing can be effectively avoided.

[0213] Of course, in some other embodiments, the butting rib 49 can be provided on the first sealing plate or on both the first sealing plate and the second sealing plate at the same time.

[0214] In some embodiments of the present application, referring to Figure 28 , when the air conditioner indoor unit 100 is hoisted, the free end of the butting rib 49 extends in the vertical direction and the first flanging 91 is vertically arranged. During assembly, the side surface of the first flanging 91 presses the sponge layer to abut against the side surface of the butting rib 49.

[0215] In this embodiment, the side surface of the first flanging and the side surface of the butting rib are tightly sealed in a surface contact manner, completely avoiding the problem of air leakage due to manufacturing errors and manual operation errors.
