Description

Technical Field

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

[0002] The air conditioner generally includes an indoor unit and an outdoor unit, wherein the indoor unit includes a housing and an indoor heat exchanger. The housing may include a base and an outer cover, wherein the outer cover is disposed on the base and forms a receiving space with the base. An end plate is generally disposed at one end of the indoor heat exchanger, and the end plate is connected to the base so that the indoor heat exchanger is fixed to the base.

[0003] In the related art, in order to ensure the stability of the indoor heat exchanger during pipe insertion, welding, storage and transportation on a work vehicle, a protruding support portion is usually added to the end plate. The support portion is protruding from the end of the end plate away from the indoor heat exchanger and is used as a support point to support the indoor heat exchanger when the indoor heat exchanger is placed vertically.

[0004] Although a certain gap is reserved between the added support part and the outer cover, the outer cover cannot be made longer due to the size limitation of the air conditioner indoor unit, and the gap between the end plate and the inner part of the outer cover is limited, making it difficult to make the gap between the end plate and the side plate of the outer cover very large. The size of the gap is any value between 5mm and 30mm. Because the indoor heat exchanger is heavy, the support part of the air conditioner indoor unit is easy to collide with the inner side of the outer cover when it falls, resulting in appearance problems such as broken appearance parts and white marks, which makes the product less competitive in the market. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end,

[0006] According to an embodiment of the present disclosure, an air conditioner indoor unit is provided, comprising:

[0007] A housing comprising:

[0008] Base;

[0009] An outer cover is disposed on the base and forms a receiving space with the base, the outer cover includes side panels, and the side panels are located at both ends of the housing in the length direction thereof;

[0010] An indoor heat exchanger is arranged in the accommodation space along the length direction of the casing;

[0011] an end plate, provided at one end of the indoor heat exchanger in the length direction thereof, the end plate being connected to the base so that the indoor heat exchanger is fixed to the base;

[0012] A support portion protruding from one end of the end plate away from the indoor heat exchanger;

[0061] The utility model provides an air conditioner indoor unit 100, as shown below Figures 1 to 21 The air conditioner indoor unit 100 is described. Figure 1 , Figure 2 1 is an appearance diagram of an air conditioner indoor unit 100, which is a part of the air conditioner, and is arranged indoors for exchanging heat with the indoor environment. In addition, the air conditioner also includes an air conditioner outdoor unit, which is usually arranged outdoors for bringing indoor heat to the outdoors.

[0062] refer to Figure 1 to Figure 3 In an exemplary embodiment of the air conditioner indoor unit 100 of the present invention, the air conditioner indoor unit 100 may include a casing 1. The casing 1 is installed indoors, and the casing 1 forms the overall appearance of the air conditioner indoor unit 100.

[0063] The housing 1 is in the shape of a rectangular parallelepiped, and the left and right ends of the housing are the two ends of the housing in the length direction thereof.

[0064] An accommodation space is formed inside the casing 1. The accommodation space is used to accommodate and fix various components in the air conditioner indoor unit 100, which can prevent foreign objects from colliding with the various components in the casing 1, thereby improving the reliability of the air conditioner indoor unit 100 during transportation or installation.

[0065] In some embodiments of the present application, reference Figure 1 , the housing 1 may include an air inlet 13 .

[0066] The air inlet 13 is communicated with the installation cavity, and serves as an inlet for the external air of the housing 1 to flow in, allowing the indoor air to enter the installation cavity through the air inlet 13 .

[0067] In some embodiments of the present application, reference Figure 2 , the housing 1 may include an air outlet 14 .

[0068] The air outlet 14 is communicated with the installation cavity, and serves as an outlet for the heat exchange airflow in the housing 1 to flow out, allowing the airflow in the installation cavity to flow out through a plurality of air outlets 14 .

[0069] In some embodiments of the present application, the air inlet 13 may be opened at the top of the housing 1 , and the air outlet 14 may be opened at the front side of the housing 1 .

[0070] The air outlet 14 is long and can be extended along the length of the housing 1, thereby improving the aesthetics of the air conditioner indoor unit 100. In this embodiment, when the air conditioner indoor unit is working, the air conditioner indoor unit 100 takes in air from the upper side and discharges air toward the front side, which is convenient for setting.

[0071] Of course, in other embodiments of the present application, the positions of the air inlet 13 and the air outlet 12 can also be set at other positions as long as the air inlet and air outlet requirements can be met.

[0072] It should be noted that the direction described in the article is based on the direction in which the user faces the air-conditioning indoor unit, wherein the side of the air-conditioning indoor unit facing the user when in use is defined as the front side, the opposite side is defined as the rear side, and the left and right sides are distinguished based on the direction in which the user faces the air-conditioning indoor unit.

[0073] In some embodiments of the present application, reference Figure 4 The air conditioner indoor unit 100 may include an indoor heat exchanger 2. The indoor heat exchanger 2 extends along the length direction of the casing 1, and the indoor heat exchanger 2 is arranged in the accommodating space for heat exchange with the airflow in the casing 1.

[0074] In some embodiments of the present application, the air-conditioning indoor unit 100 may include an indoor fan 3 .

[0075] The indoor fan 3 is arranged in the accommodating space, and is used to drive the indoor air outside the casing 1 to enter the accommodating space in the casing through the air inlet. The indoor fan 3 drives the air in the accommodating space to flow along the air inlet 13 toward the air outlet 14.

[0076] The indoor heat exchanger 2 may be located inside the air inlet 13. The indoor fan 3 may be located on a side of the indoor heat exchanger 2 away from the air inlet 13. That is, in the airflow direction in the casing 1, the indoor fan 3 is located downstream relative to the indoor heat exchanger 2.

[0077] When the air conditioner indoor unit 100 is running, driven by the indoor fan 3, the indoor air enters the accommodating space through the air inlet 13, the indoor air in the accommodating space flows through the indoor heat exchanger 2 for heat exchange, and the heat exchanged air flows outwardly to the room through the air outlet 14, so that the air conditioner cools and heats, plays a role in regulating the indoor temperature to achieve a comfortable temperature for the user.

[0078] In some embodiments of the present application, the air-conditioning indoor unit 100 may include an air guide plate 15 .

[0079] The air guide plate 15 is rotatably connected to the housing 1, and is disposed at the air outlet 14. The air guide plate 15 opens or closes the air outlet 14. When the air guide plate 15 opens the air outlet 14, the air guide plate 15 is used to guide the heat exchange airflow.

[0080] In some embodiments of the present application, the air-conditioning indoor unit 100 may include an air inlet grille 16 .

[0081] The air inlet grille 16 is disposed at the air inlet 13 to filter the air and prevent larger impurities from entering the accommodation space.

[0082] The air conditioner outdoor unit may include an outdoor housing. An installation cavity may be provided in the outdoor housing.

[0083] The outdoor housing may include an outdoor air inlet, which may be in communication with the installation cavity and may be used to introduce outdoor air into the installation cavity.

[0084] The outdoor housing may include an outdoor air outlet, which may be in communication with the installation cavity and may be used to guide the air in the installation cavity out of the installation cavity.

[0085] The air conditioner outdoor unit may include an outdoor heat exchanger. The outdoor heat exchanger may be arranged in the installation cavity.

[0086] The air conditioner outdoor unit may include an outdoor fan. The outdoor fan may be arranged in the installation cavity.

[0087] The rotation of the outdoor fan causes outdoor air to enter the installation cavity from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the installation cavity from the outdoor air outlet.

[0088] The air conditioner may include a compressor. The compressor is arranged in the installation cavity.

[0089] The air conditioner may include a throttling device. The throttling device is used for throttling. The throttling device may be provided in the air conditioner indoor unit 100 or the air conditioner outdoor unit.

[0090] 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 supplies refrigerant to the air that has been conditioned and heat exchanged.

[0091] The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0092] The condenser condenses the compressed refrigerant into liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0093] The throttle device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0094] The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0095] The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0096] Of the indoor heat exchanger and the outdoor heat exchanger, one 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 a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0097] refer to Figure 5 In some embodiments of the present application, the housing 1 may include a base 11. The base 11 forms the rear side of the air conditioner indoor unit 100, and the base 11 is suitable for hanging on a wall.

[0098] The housing 1 may include an outer cover 12. The outer cover 12 is disposed on the base 11, and a receiving space is formed between the outer cover 12 and the base 11.

[0099] The outer cover 12 is roughly in the shape of a rectangular parallelepiped frame. The rear side of the outer cover 12 is open, and the outer cover 12 is arranged on the front side of the base 11 and connected with the base 11 to form the housing 1.

[0100] The outer cover 12 may include side panels 121. The side panels 121 are located at both ends of the housing 1 in its length direction.

[0101] In some embodiments of the present application, the outer cover 12 can be provided as an integral body. Of course, in some other embodiments, the outer cover 12 can be provided as a separate body.

[0102] In some embodiments of the present application, reference Figure 6 The air conditioning indoor unit 100 may include an end plate 4 .

[0103] The end plate 4 may be disposed at one end of the indoor heat exchanger 2 in the length direction thereof.

[0104] The end plate 4 may be connected to the base 11 so that the indoor heat exchanger 2 is fixed to the base 11 .

[0105] The end plate 4 is used to support the indoor heat exchanger 2 .

[0106] The end plate 4 is disposed at one end of the indoor heat exchanger 2 , for example, the left end, to avoid stress concentration in the connection structure of the indoor heat exchanger 2 and improve the structural stability of the indoor heat exchanger 2 .

[0107] The indoor heat exchanger 2 is installed on the end plate 4. The end plate 4 can be formed into a ring frame structure. The end plate 4 can be sleeved on the end of the indoor heat exchanger 2.

[0108] By setting the end plate 4 to be clamped with the base 11, the end plate 4 can not only effectively fix the indoor heat exchanger 2 on the base 11, but also prevent the indoor heat exchanger 2 from hitting the casing 1 due to inertia of falling, thereby improving the structural stability and service life of the air-conditioning indoor unit 100.

[0109] The indoor heat exchanger 2 is a finned heat exchanger, and other types of heat exchangers may also be used.

[0110] refer to Figure 7 The indoor heat exchanger 2 may include a mounting body 21. The mounting body 21 is the main body of the indoor heat exchanger. The mounting body 21 is in a plate shape.

[0111] The indoor heat exchanger 2 may include a heat exchange tube 22. The heat exchange tube 22 is inserted into the installation body 21 and is in a bent and coiled form.

[0112] A refrigerant is arranged in the heat exchange tube 22 , and the flow of the refrigerant in the heat exchange tube 22 can bring indoor heat to the outdoors, thereby achieving the purpose of heat exchange of the indoor heat exchanger 2 .

[0113] The end of the heat exchange tube 22 is configured as a bending portion, and the bending portion is an arc-shaped bending structure, so that the heat exchange tube 22 can be bent and arranged in the limited space inside the casing 1 to arrange a longer heat exchange tube 22. In this way, the contact area between the heat exchange tube 22 and the indoor air can be increased, thereby improving the heat exchange capacity of the indoor heat exchanger 2.

[0114] In some embodiments of the present application, continue to refer to Figure 7 A plurality of mounting holes 42 are provided in the end plate 4. The mounting holes 42 are provided for the bent portions of the heat exchange tubes to pass through.

[0115] The mounting hole 42 may be sleeved on the bent portion, thereby providing good protection for the indoor heat exchanger 2, improving the stability of the indoor heat exchanger 2 and extending its service life.

[0116] When the indoor heat exchanger is inserted into the pipes, welded, stored, or transported on a work vehicle, a protruding support portion 41 is usually added to the end plate 4 to ensure the stability of the placement. The support portion 41 is protruding from the end of the end plate 4 away from the indoor heat exchanger 2, and is used to support the indoor heat exchanger 2 as a support point when the indoor heat exchanger 2 is placed vertically.

[0117] Among them, reference Fig. 9 , two supporting parts 41 may be provided.

[0118] The support portion 41 is added to the end plate 4 to ensure the placement stability of the indoor heat exchanger 2. After the indoor heat exchanger 2 is installed, a gap is formed between the support portion 41 and the side plate 121. Due to the size limitation of the air conditioner indoor unit 100, the outer cover 12 cannot be made longer, and the gap between the end plate 4 and the side plate 121 is limited, making it difficult to make the gap formed between the support portion 41 and the side plate 121 large.

[0119] Continue to refer Fig. 9 , the dimension of the gap b formed between the support part 41 and the side plate 121 in the length direction of the housing 1 is not greater than 30 mm. The gap formed between the support part 41 and the side plate 121 is small and the weight of the indoor heat exchanger 2 is large, so that the support part 41 of the air conditioner indoor unit 100 is easy to collide with the inner side of the side plate 121 at the moment of falling, resulting in the appearance part (outer cover 12) breaking and white marks and other problems.

[0120] In this embodiment, in order to facilitate the assembly of the air conditioner indoor unit, the gap b formed between the support portion 41 and the side plate 121 is set to be no less than 5 mm. In other words, the size of the gap b in the length direction of the housing is any value between 5 mm and 30 mm.

[0121] refer to Fig.10 , taking a common outer cover 12 assembly form as an example: the outer cover 12 and the base 11 are assembled by a hook structure 7 and fixed with multiple screws. In order to achieve an integrated appearance, the upper side is usually fixed with a hook. This structure can make the air conditioner look more beautiful, but the fixation is slightly worse than that of using many screws to fix. In this structure, the movement between the indoor heat exchanger 2 and the outer cover 12 will also be relatively large.

[0122] In order to effectively cushion the impact force of the end plate 4 on the outer cover 12 during the falling process, refer to Fig.11 , the air conditioner indoor unit 100 may include a buffer structure 5. The buffer structure 5 is arranged in the gap.

[0123] refer to Fig.12 , Fig.13 The projection of the buffer structure 5 on the indoor heat exchanger 2 along the length direction of the housing 1 covers the support part 41. In the gap, the buffer structure 5 is arranged at the position corresponding to the support part 41 on the end plate 4, which can effectively prevent the support part 41 from colliding with the side plate 121 during falling or transportation, resulting in the appearance part being broken and white printing.

[0124] In some embodiments of the present application, in the length direction of the housing 1 , the ratio of the thickness of the buffer structure 5 to the size of the gap is 0.7-1.

[0125] The ratio of the thickness of the buffer structure 5 to the size of the gap is set within a reasonable range, and the appearance part is effectively protected on the basis of avoiding increasing the appearance size, so as to avoid the problem of breakage or white mark caused by impact on the appearance part.

[0126] In some embodiments of the present application, reference Fig. 9 , Fig.15 In the length direction of the housing 1, the ratio of the thickness d of the buffer structure 5 to the size b of the gap is c. 0.7≤c. c≤1.

[0127] If the thickness d of the buffer structure 5 is too small, it cannot effectively play a buffering role. In order to ensure that the impact force of the support portion 41 on the end plate 4 is effectively buffered when the indoor heat exchanger 2 moves, the ratio of the thickness of the buffer structure 5 to the gap size is set to be greater than or equal to the first parameter value. For example, the first numerical parameter can be 0.7, 0.75, or 0.8. Consider selecting a suitable and specific parameter in the specific design.

[0128] If the thickness d of the buffer structure 5 is too large, the gap between the side plate 121 and the support portion 41 will be too large, which will in turn cause the appearance size of the air conditioner indoor unit 100 to be too large. Due to the appearance size limit of the air conditioner indoor unit 100, the ratio of the thickness of the buffer structure 5 to the gap size is set to be less than or equal to the second parameter value. For example, the second numerical parameter can be 1, 0.95, or 0.9. Consider selecting a suitable and specific parameter in the specific design.

[0129] It should be noted that, in the specific design, the projection of the buffer structure 5 needs to cover all the supporting parts 41, and the tolerance of movement in all directions during the falling process is fully calculated and finally determined based on the actual tolerance accumulation calculation, and the buffer structure 5 needs to cover the entirety. The specific thickness of the buffer structure 5 needs to be determined based on the comprehensive calculation of the weight of the indoor heat exchanger 2 and the fixing form of the outer cover 12 to select the appropriate parameters.

[0130] In some embodiments of the present application, in the direction from the side plate 121 to the indoor heat exchanger 2 , at least a portion of the buffer structure 5 overlaps with the support portion 41 .

[0131] By arranging at least part of the buffer structure 5 to overlap with the support portion 41 in the direction from the side plate 121 to the indoor heat exchanger 2, the air conditioner indoor unit 100 can avoid the support portion 41 directly hitting the side plate 121 at the moment of falling. The buffer structure 5 effectively buffers the impact force of the end plate 4 on the outer cover 12 during the falling process, so that the side plate 121 of the outer cover 12 will not have white marks due to collision when the air conditioner indoor unit 100 is actually dropped or transported violently, thereby improving the product competitiveness.

[0132] In some embodiments of the present application, the buffer structure 5 is a sponge or a rubber pad or is made of EVA material. Fig.16 , Fig.17 , the buffer structure 5 can be a single-layer structure.

[0133] EVA (ethylene-vinyl acetate copolymer) refers to ethylene-vinyl acetate copolymer. The buffer structure 5 made of EVA material has the advantages of good softness, shock resistance, anti-slip and strong pressure resistance.

[0134] Sponge, rubber pad or EVA material are all relatively soft materials, and are placed between the two relatively hard structural parts of the side plate 121 and the support part 41 to play a buffering role and solve the problem of white marks on the appearance.

[0135] In some embodiments of the present application, the buffer structure 5 may include a first spacer 51 .

[0136] In some embodiments of the present application, the buffer structure 5 may include a second spacer 52 .

[0137] refer to Fig.18 , Fig.19 The first partition layer 51 and the second partition layer 52 are arranged along the length direction of the housing 1 .

[0138] The density of the first interlayer 51 is greater than that of the second interlayer 52 , so that the hardness of the first interlayer 51 is greater than that of the second interlayer 52 .

[0139] By arranging the first interlayer 51 and the second interlayer 52 of different densities, the buffer structure 5 has a harder first interlayer 51 and a softer second interlayer 52 , thereby enhancing the buffering capacity of the buffer structure 5 .

[0140] In some embodiments of the present application, the first partition layer 51 is made of PVC material or HIPS material.

[0141] PVC refers to polyvinyl chloride resin (Poly Vinyl Chloride), also known as PVC. HIPS material is high impact polystyrene, which has the characteristics of easy processing, excellent dimensional stability, high impact strength and high rigidity.

[0142] In some embodiments of the present application, the second barrier layer 52 is a sponge or a rubber pad or is made of EVA material. The sponge may be a rubber sponge or a PU sponge.

[0143] The buffer structure 5 buffers and releases the impact force of the support part 41. When the impact force of the support part 41 is large, even if a white mark is formed at the position of the harder first interlayer 51, the softer second interlayer 52 such as sponge can buffer the entirety and avoid white marks on the side panel 121.

[0144] In some embodiments of the present application, the first partition layer 51 is closer to the side plate 121 than the second partition layer 52 .

[0145] refer to Fig.19 In this embodiment, the first insulation layer 51 is attached to the side of the side plate 121 close to the indoor heat exchanger 2. The first insulation layer 51 is closer to the side plate 121 than the second insulation layer 52. The second insulation layer 52 can be attached to the side of the first insulation layer 51 close to the indoor heat exchanger 2, or the second insulation layer 52 can be attached to the side of the support portion 41 away from the indoor heat exchanger 2.

[0146] Continue to refer Fig.19 The first interlayer 51 with a higher density (hardness) is relatively isolated from the second interlayer 52 close to the side panel 121, so that when the appearance part (side panel 121) that is prone to white marks is hit again, the inner side of the side panel 121 can contact the harder first interlayer 51, and the second interlayer 52 with a lower density plays a buffering role in the middle. Even if white marks are produced on the first interlayer 51 with a higher density, it is difficult to be transmitted to the appearance surface of the side panel 121, thereby effectively protecting the appearance parts.

[0147] In some embodiments of the present application, the second partition layer 52 is closer to the side plate 121 than the first partition layer 51 .

[0148] The second interlayer 52 is closer to the side panel 121 than the first interlayer 51, so that the support portion 41 collides with the first interlayer 51 with a larger density first, thereby dispersing and releasing some stress; the second interlayer 52 with a smaller density then acts as a buffer. Even if white marks are generated after the first interlayer 51 collides with the support portion 41, the second interlayer 52 will not cause white marks on the corresponding position of the side panel 121, so that the buffer structure 5 as a whole can avoid white marks or fractures on the front side (exterior surface) of the side panel 121, thereby improving product competitiveness.

[0149] In some embodiments of the present application, the first insulation layer 51 can be attached to the side of the side plate 121 close to the indoor heat exchanger 2. Of course, in some other embodiments, the second insulation layer 52 can be attached to the side of the side plate 121 close to the indoor heat exchanger 2.

[0150] The first partition layer 51 or the second partition layer 52 is pasted on the inner side of the side plate 121 corresponding to the support portion 41, which can effectively avoid the problem of appearance parts being broken and white marks caused by collision.

[0151] In some embodiments of the present application, the first spacer 51 and the second spacer 52 are adhered together.

[0152] by Fig.19 For example, the buffer structure 5 is entirely pasted on the side plate 121. The first interlayer 51 is pasted on the side of the side plate 121 close to the indoor heat exchanger 2, and the second interlayer 52 can be pasted on the side of the first interlayer 51 close to the indoor heat exchanger 2.

[0153] Of course, in some other embodiments, the buffer structure 5 can be adhered to the supporting portion 41 as a whole.

[0154] In some embodiments of the present application, the first partition layer 51 and the second partition layer 52 may be provided separately.

[0155] When the first partition layer 51 and the second partition layer 52 are separately provided, the first partition layer 51 is closer to the side plate 121 relative to the second partition layer 52, and the first partition layer 51 can be provided on the side plate 121, and the second partition layer can be provided on the support portion 41. The second partition layer 52 is closer to the side plate 121 relative to the first partition layer 51, and the second partition layer 52 can be provided on the side plate 121, and the first partition layer can be provided on the support portion 41.

[0156] In some embodiments of the present application, the thickness of the first spacer 51 is smaller than the thickness of the second spacer 52 .

[0157] By providing a buffer structure 5 composed of interlayers of different densities, compared with a single-layer buffer structure 5 , the buffer structure 5 has a stronger buffering capacity and the overall thickness of the buffer structure 5 can be reduced.

[0158] In some embodiments of the present application, reference Fig.15 , the thickness of the first partition layer 51 is a. 0.5 mm ≤ a. a ≤ 3 mm. The thickness of the first partition layer 51 is the distance between the two end surfaces of the first partition layer 51 in the length direction of the housing 1.

[0159] In the length direction of the housing, the thickness of the first interlayer 51 is too small, and the white mark problem may not be completely solved when the support portion 41 has a large impact force. In order to further improve the buffering capacity of the buffer structure 5, the thickness of the first interlayer 51 is set to be greater than or equal to the third parameter value. For example, the first numerical parameter can be 0.5 mm, 0.6 mm, or 0.7 mm. Consider selecting a suitable and specific parameter in the specific design.

[0160] If the thickness of the first interlayer 51 is too large, the cost of the buffer structure 5 will be increased. In order to reduce the cost of the buffer structure 5, the thickness of the first interlayer 51 is set to be less than or equal to the fourth parameter value. For example, the fourth numerical parameter can be 3 mm, 2.9 mm, or 2.8 mm. Consider selecting a suitable and specific parameter in the specific design.

[0161] In some embodiments of the present application, the buffer structure 5 may be disposed between the outer cover 12 and other structural members inside the accommodation space. Fig. 20 , Fig.21 The buffer structure 5 may be disposed between the front panel 122 of the outer cover 12 and the display box 6 .

[0162] The buffer structure 5 acts as a buffer between the outer cover 12 and the display box. The force of the display box during the falling and transportation of the whole machine is effectively released through the buffer structure 5 to avoid the impact inside the outer cover 12 to produce white marks on the front of the outer cover 12.

[0163] The air conditioner indoor unit 100 provided by the utility model is provided with a buffer structure 5 in the gap formed between the support portion 41 on the end plate 4 of the indoor heat exchanger 2 and the side plate 121, so that the buffer structure 5 plays a buffering role between the side plate 121 and the support portion 41. The impact force of the support portion 41 on the side plate 121 during the falling and transportation of the whole machine is effectively released by the buffer structure 5, so as to avoid the impact on the inner side of the side plate 121 to cause white marks on the front side (exterior surface) of the side plate 121.

[0164] The buffer structure 5 may include a first interlayer 51 with a relatively large density and a second interlayer 52 with a relatively small density. When the whole machine is dropped or transported, if the impact force on the support portion 41 is large, the double-layer buffer structure 5 can effectively buffer and release the impact force. Even if a white mark is produced at the first interlayer 51, the second interlayer 52 can buffer the entire structure, avoiding the white mark on the front of the side panel 121, and effectively preventing the indoor heat exchanger 2 from colliding during the drop and transportation of the air conditioner indoor unit 100, resulting in a poor appearance.
