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] An 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 at least includes an air inlet of the air conditioner communicating with the interior and an air outlet of the air conditioner. 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 to the interior 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 when the indoor unit is floor-mounted or ceiling-mounted.

[0004] In order to drain the condensed water in the water receiving tray in time, in the related art, the water receiving tray usually has a drain port opened at the bottom end (lower side) on the left side when it is floor-mounted. The drain port extends downward and is connected to a drain pipe. The left side of the indoor heat exchanger is limited by the position of the lower drain port and cannot move to the left, otherwise the drain port will be blocked, affecting the outflow of the condensed water. The overall indoor heat exchanger cannot move to the left, resulting in a relatively large space on the left side of the indoor heat exchanger, affecting the size of the housing, causing the length direction of the housing to be relatively large, which is not conducive to the miniaturization design of the model. At the same time, it increases the sea freight cost and affects the market competitiveness. Summary of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems in the related art to some extent. For this reason,

[0114] The rotation of the outdoor fan causes outdoor air to enter the heat exchange air duct from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor heat exchange air duct through the outdoor air outlet.

[0115] The air conditioner may include a compressor. The compressor is disposed in the outdoor heat exchange air duct.

[0116] 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.

[0117] 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.

[0118] 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. The discharged refrigerant gas flows into the condenser.

[0119] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0120] The throttling device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0121] 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.

[0122] The evaporator can achieve the refrigeration effect by using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0123] In both 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 is used as a heater in the heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in the cooling mode.

[0124] In some embodiments of the present application, referring to Figure 4 、 Figure 8 , the indoor unit 100 of the air conditioner may include a water receiving tray 4.

[0125] Referring to Figure 5 , the water receiving tray 4 is disposed 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.

[0126] Among them, when the indoor unit 100 of the air conditioner 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 indoor unit 100 of the air conditioner caused by the condensed water, and also avoid the condensed water seeping out of the housing 1 and dripping, affecting the user experience.

[0127] Furthermore, in order to timely drain the condensed water contained in the water receiving tray 4, the air conditioner indoor unit 100 may include a drain port 41.

[0128] 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.

[0129] In the related art, in the position of the left U-tube of the indoor heat exchanger 2, the space is relatively large, mainly limited by the position of the bottom drain port 41. This part of the space affects the size of the whole machine housing 1, 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 freight container cost.

[0130] 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.

[0131] By arranging the drain port 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 port 41 when the drain port 41 is arranged at the bottom of the drain tray, so that the installation space on the drain port 41 side of the indoor heat exchanger 2 becomes smaller, and the corresponding size of the water receiving tray 4 can be correspondingly reduced, so that the length of the entire housing 1 can be reduced, the sea freight container loading capacity can be improved, and the transportation cost can be reduced. On the other hand, one end of the indoor heat exchanger 2 can increase in size toward the drain port 41, and under the condition that the size of the housing 1 remains unchanged, the heat exchange area can be increased.

[0132] As Figure 8 shown, in this embodiment, the drain port 41 is opened at the left end of the water receiving tray 4 when the air conditioner indoor unit 100 is installed in a sitting position.

[0133] In this embodiment, the position of the drain port 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 port 41 and can move to the left. When the indoor heat exchanger 2 moves to the left, it will not block the drain port 41, and at the same time, the space on the left side of the indoor heat exchanger 2 is reduced, the overall size of the air conditioner indoor unit is reduced, the miniaturization of the housing 1 of the air conditioner indoor unit is satisfied, and the overall cost is reduced. In addition, the smaller overall size makes the overall packaging size smaller, increases the number of units installed in the sea freight container, reduces the sea freight, and improves the market competitiveness.

[0134] The end plate of the two end plates that is sleeved on the outside of the bent end 22 is defined as the first end plate 23 , and the other end plate is defined as the second end plate 24 . The drain port 41 is disposed near the first end plate 23 .

[0135] refer to Figure 7 The first end plate 23 is provided with a plurality of avoidance holes 231, through which the bent ends 22 of the heat exchange tubes pass. The avoidance holes 231 can be sleeved on the bent ends 22, thereby providing good protection for the indoor heat exchanger 2, improving the stability of the indoor heat exchanger 2 and extending its service life.

[0136] The drain port 41 is provided on the sidewall of one end of the water receiving pan 4 in the longitudinal direction. The bent end 22 of the heat exchange tube of the indoor heat exchanger 2 can be moved toward the drain port 41, thereby reducing the installation space of the indoor heat exchanger 2. The bent end 22 of the heat exchange tube has a simple structure. During movement, only a safe distance between the heat exchange tube and the side panel 17 needs to be maintained. This facilitates the overall movement of the indoor heat exchanger 2 and improves its mobility.

[0137] In some embodiments of the present application, the air-conditioning indoor unit 100 may include a drainage assembly 5 .

[0138] refer to Figure 9 The water inlet end of the drainage component 5 is connected to the drainage port 41 , and the drainage end of the drainage component 5 extends to the outside of the shell 1 to drain the condensed water in the water receiving tray 4 to the outside of the shell 1 .

[0139] The two side covers are respectively a first side cover 181 and a second side cover 182 . The side cover closer to the drain outlet 41 is defined as the first side cover 181 . The drain assembly 5 is disposed inside the first side cover 181 .

[0140] Specifically, the drainage assembly 5 is disposed in the first side cover 181 , and the user cannot directly see the drainage assembly 5 , thereby improving the appearance of the entire machine.

[0141] refer to Figure 9 、 Figure 10 The first side cover 181 is connected to one side plate 17 thereof, and a first accommodation space is formed between the first side cover 181 and one side plate 17 thereof, and the drainage assembly 5 is arranged in the first accommodation space.

[0142] The first accommodating space is located outside the linear air duct, that is, the drainage component 5 does not occupy the position of the second inner cavity 193, so as to avoid affecting the air intake volume of the air-conditioning indoor unit 100.

[0143] Further, refer to Figure 9 The first side cover 181 is provided with an escape portion 6 , and the escape portion 6 allows the drainage assembly 5 to penetrate and extend to the outside of the shell 1 .

[0144] Among them, the avoidance portion 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.

[0145] In some embodiments of the present application, in order to improve the versatility when the air conditioner indoor unit 100 is installed, the avoidance portion 6 can be opened on the first side wall 1811 and the second side wall 1812 of the first side cover 181.

[0146] 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, 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.

[0147] When the air conditioner indoor unit 100 is installed, the drainage end of the drainage component 5 can penetrate through one of the avoidance portions 6 and extend to the outside of the housing 1. That is to say, when installed, 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 extends out from the rear side of the first side cover 181 for drainage. Among them, the drainage component 5 penetrates through the avoidance portion 6 at the rear side of the first side cover 181 and extends out for drainage, which does not affect the overall appearance of the machine and is beneficial to improving the overall aesthetics.

[0148] In some embodiments of the present application, the drainage component 5 is rotatably arranged relative to the drainage port 41, which is convenient for adjusting the position of the drainage component 5. When the air conditioner indoor unit 100 is installed, it can be selected to extend out for drainage from the bottom end or the rear side by rotating the drainage component 5 according to the actual installation scenario.

[0149] In some embodiments of the present application, the drainage component 5 can 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 L-shaped.

[0150] The drainage component 5 can include a drainage pipe 52. One end of the drainage pipe 52 is connected to the end of the water pipe elbow 51 far from the drainage port 41, and the drainage pipe 52 penetrates 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 for redirecting the flow direction.

[0151] In this embodiment, the water pipe elbow 51 can be rotated 90° at the drainage port 41 for installation, so that the drainage pipe 52 can be switched from the state of penetrating through one avoidance portion 6 to the state of penetrating through another avoidance portion 6.

[0152] 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.

[0153] Reference Figure 10 , which is that the pipeline cover 7 shields 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, the user cannot observe the drainage assembly 5 inside the first side cover 181, further improving the overall aesthetics of the machine.

[0154] 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.

[0155] 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 on a base.

[0156] 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.

[0157] The water receiving tray 4 may include two side water retaining portions 44. The two side water retaining portions 44 surround both ends of the first water receiving portion 42 and the second water receiving portion 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. Among them, the water receiving cavity is a structure with an open upper end, which is convenient for collecting condensed water.

[0158] It should be noted that the projection of the indoor heat exchanger 2 in the vertical direction is located inside 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.

[0159] Reference Figure 13 , the drain port 41 is arranged at a position of the side water retaining portion 44 close to the second water receiving portion 43. This arrangement enables the condensed water in the first water receiving portion 42 and the second water receiving portion 43 to flow out from the drain port 41.

[0160] In some embodiments of the present application, both ends in the length direction of the water receiving tray 4 are detachably connected to the two side plates 17.

[0161] In the related art, the water receiving tray 4 is installed by screws and lacks a positioning structure during installation. When installing the water receiving tray 4, workers need to first hold the water receiving tray 4 by hand, 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.

[0162] To solve the above technical problems, in this embodiment, a positioning structure is adopted for positioning and installing the water receiving tray 4.

[0163] Specifically, referring to Figure 14 , at both ends in the length direction of the water receiving tray 4, limiting portions 46 are protruded, and notches 173 adapted to be connected with the limiting portions 46 are arranged on the side plates 17. The limiting portions 46 are adaptively connected with the notches 173 to realize the installation and positioning of the water receiving tray 4.

[0164] In this embodiment, there are two limiting portions 46, and two notches 173 are also configured. The two limiting portions 46 are adaptively connected with the two notches 173 to realize the four-point positioning of the water receiving tray 4.

[0165] Furthermore, at both ends in the length direction of the water receiving tray 4, connecting portions 47 are protruded, and mounting portions 174 corresponding to the connecting portions 47 are arranged on the side plates 17. The connecting portions 47 and the mounting portions 174 are fixedly connected by first fasteners, so that the water receiving tray 4 and the side plates 17 are detachably connected. Among them, the first fastener can be a screw, and both the connecting portions 47 and the mounting portions 174 are screw through holes.

[0166] In this embodiment, when a worker installs the water receiving tray 4, first install the two limiting portions 46 on one side, and then install the two limiting portions 46 on the other side. In this way, the four limiting portions 46 of the water receiving tray 4 are all adaptively connected into the four notches 173 to realize four-point positioning, ensuring the accurate left, right, front and back positions of the water receiving tray 4, so that the position of the water receiving tray 4 is not deviated and no manual adjustment is required by the worker. After positioning, the connecting portions 47 and the mounting portions 174 are correspondingly arranged, and the fasteners can be directly fixed at the position of the mounting portions 174, improving the assembly efficiency.

[0167] In the related art, the water receiving tray 4 is connected with the side plates 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 plates 17, and the air inlet panel 12 is placed on the water receiving tray 4. Since there is only one screw for fixing on each side of the connection between the water receiving tray 4 and the side plates 17, it is very easy to cause the screw through holes on the water receiving tray 4 where the air inlet panel 12 and the side plates 17 are connected and fixed to be offset. The screw holes of the air inlet panel 12 and the side plates 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 they cannot be installed or the worker needs to manually correct the position and adjust it to the concentric position before installing the screws.

[0168] 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 plates 17 and the air inlet panel 12. When the force of using an electric screw for installation is a little larger, the plastic water receiving tray 4 sometimes will be extruded with cracks, and it is very easy to cause quality accidents.

[0169] In some embodiments of the present application, a plurality of convex portions 45 are provided at both ends of the water receiving tray 4, and the plurality of convex portions 45 are arranged at intervals in the first direction. In this embodiment, there are three convex portions 45.

[0170] Reference Figure 14 , 19 , the end faces of the three convex portions 45 facing the water receiving tray 4 protrude away from the center of the water receiving tray 4. Two limiting portions 46 and a connecting portion 47 are respectively provided on the three convex portions 45 in one-to-one correspondence.

[0171] In this embodiment, the three convex portions 45 are provided on the side water retaining portion 44.

[0172] Reference Figure 15 , a second flanging 171 is provided on the side plate 17, and a recessed portion 172 adapted to the three convex portions 45 is formed on the second flanging 171. Among them, there is a gap between the recessed portion 172 and the air inlet panel 12, and two notches 173 and mounting portions 174 are respectively provided on the three recessed portions 172 in one-to-one correspondence.

[0173] During assembly, the three convex portions 45 on the water receiving tray 4 are respectively inserted into the three recessed portions 172, and the limiting portions 46 are engaged with the notches 173, realizing 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.

[0174] There is a gap between the recessed 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 first fasteners passing through the fastener through holes of the air inlet panel 12, improving the installation speed, and thus increasing the production efficiency.

[0175] Furthermore, reference Figure 16 , Figure 17 , first connection holes 121 are provided at both ends in the length direction of the air inlet panel 12, and second connection holes 175 are provided on the second flanging 171.

[0176] Among them, when the limiting portion 46 is adaptively connected to the notch 173, the first connection hole 121 and the second connection hole 175 are correspondingly arranged and fixedly connected by the second fasteners.

[0177] Reference Figure 18 , the three convex portions 45 are located between the air inlet panel 12 and the side plate 17, and the air inlet panel 12 and the side plate 17 are fixedly connected separately by the second fasteners, without the second fasteners passing through the fastener through holes (connecting portion 47) of the water receiving tray 4, improving the installation speed, and thus increasing the production efficiency.

[0178] In this embodiment, by providing four limiting portions 46 on the water receiving tray 45, when assembling, it is directly clamped into the notch 173 on the recessed portion 172 of the side plate 17 to achieve position positioning. The water receiving tray 4 and the side plate 17 are separately fixed with the first fastener, and the air inlet panel 12 and the side plate 17 are separately connected and fixed with the second fastener. There is no need for the second fastener to pass through the connecting portion 47 of the water receiving tray 4, and the situation where the first connecting hole 121 of the air inlet panel 12 and the second connecting hole 175 are not concentric and the second fastener cannot be assembled due to the position deviation of the water receiving tray 4 is avoided. The connection of the existing three-layer structure is changed to a two-layer structure connection, which improves the installation speed and thus improves the production efficiency.

[0179] Reference Figure 19 , third flanges 122 are provided at both ends of the air inlet panel 12 in the length direction. Among them, the first connecting hole 121 is opened on the third flange 122.

[0180] 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 wire routing portion 461 is provided for routing wires and can cooperate with the side-end wire routing of the air conditioner indoor unit 100.

[0181] In some embodiments of the present application, in order to realize the installation and positioning of the indoor heat exchanger 2, a positioning surface 48 is formed on the water receiving tray 4.

[0182] 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 surface of the indoor heat exchanger 2. Among them, the positioning surface 48 is inclined to adapt to the inclined installation of the direct-discharge type indoor heat exchanger 2.

[0183] The first end surface 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.

[0184] 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 surface 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 is a gap and non-conformity between the first end surface of the indoor heat exchanger 2 and the positioning surface 48, and there will be a gap, resulting in the problem of air leakage due to poor sealing.

[0185] 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.

[0186] 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.

[0187] A guiding surface 81 is formed on the guiding member 8. In a 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. Refer to Figure 21 , in a cross-section of the water receiving tray 4 perpendicular to the length direction of the housing 1, the end of the guiding surface 81 far 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.

[0188] In 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 that the contact length between the first end face of the indoor heat exchanger 2 and the positioning surface 48 is short in the related art, resulting in the problem of inaccurate manual placement of the indoor heat exchanger 2, and avoiding the problem of gaps caused by non-fitting between the first end face of the indoor heat exchanger 2 and the positioning surface 48, resulting in air leakage due to poor sealing.

[0189] In some embodiments of the present application, refer to 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.

[0190] In 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, avoiding the influence of the guiding member 8 on the air intake volume of the indoor heat exchanger 2, which is beneficial to improving the heat exchange efficiency.

[0191] 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.

[0192] Refer to Figure 22 , in this embodiment, the water passing part 83 can be a semi-circular through hole. Of course, in some other embodiments, the water passing part 83 can be a through hole of other shapes.

[0193] By providing the water passing part 83, when the whole machine is mounted, 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.

[0194] In some embodiments of the present application, refer to Figure 25, the air conditioner indoor unit 100 may include two sealing plates 9. The two ends in the length direction of the indoor heat exchanger 2 are detachably connected to the two side plates 17 by the sealing plates 9 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, it is possible to prevent the air that has not passed through the heat exchange of the indoor heat exchanger 2 from flowing out.

[0195] 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.

[0196] Wherein, when the drain port 41 is arranged 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.

[0197] 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.

[0198] In the related art, when the indoor heat exchanger 2 is assembled, one end in the length direction of the sealing plate 9 is directly attached to 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 the assembly workers, there are often problems such as loose line contact, flashing seams, and air leakage due to poor sealing.

[0199] To solve the above technical problems, refer to Figure 26 , in this embodiment, a first flanging 91 is provided on the sealing plate 9.

[0200] Refer to Figure 27 , a butting rib 49 is provided on the first water receiving part 42, wherein a sponge layer is provided on the butting rib 49.

[0201] Refer 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 flashing seams and air leakage due to poor sealing.

[0202] In this embodiment, the butting rib 49 can be arranged 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.

[0203] Of course, in some other embodiments, the butting rib 49 can be arranged on the first sealing plate or on both the first sealing plate and the second sealing plate at the same time.

[0204] In some embodiments of the present application, refer to Figure 28, when the air conditioner indoor unit 100 is hoisted, the free end of the abutting rib 49 extends in the vertical direction and the first flanging 91 is arranged vertically. During assembly, the side surface of the first flanging 91 presses against the sponge layer and abuts against the side surface of the abutting rib 49.

[0205] In this embodiment, the side surface of the first flanging is tightly sealed with the side surface of the abutting rib, so that the contact between the two is a surface contact, which can completely avoid the problem of air leakage caused by manufacturing errors and manual operation errors.

[0206] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
