Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning, and in particular to a ceiling-mounted air conditioning indoor unit. Background Technology

[0002] Floor-mounted air conditioner indoor units typically offer both floor-mounted and ceiling-mounted installation options, providing more choices for air conditioner installation. Floor-mounted air conditioner indoor units are a common type of commercial air conditioning system, widely used in large indoor spaces such as shopping malls, supermarkets, and offices. In use, the floor-mounted air conditioner indoor unit is installed on the ceiling, saving space through concealed installation while achieving indoor temperature regulation.

[0003] A ceiling-mounted air conditioner indoor unit includes a main body and an indoor heat exchanger and a heat exchange fan housed within it. The main body includes at least an air inlet and an air outlet that communicate with the indoor environment. Indoor airflow is drawn into the main body through the air inlet by the heat exchange fan, undergoes heat exchange in the indoor heat exchanger, and then flows out of the room through the air outlet. Existing ceiling-mounted air conditioner indoor units typically have a long, narrow air guide vane on the air outlet side; the direction and distance of the airflow are adjusted by rotating the vane.

[0004] While air deflectors allow for initial control over the airflow range, they have limitations. If the deflector's rotation angle is too small, the air outlet will become smaller, resulting in reduced airflow and affecting cooling or heating performance. Furthermore, even with a smaller deflector rotation angle, the airflow from the indoor unit is poor within a small area directly below and to the side of the air outlet, causing users to feel no airflow in these areas and reducing comfort.

[0069] The ceiling-mounted air conditioner indoor unit provided by this utility model can have various implementation forms.

[0070] in, Figures 1 to 20 This is an illustrative embodiment of the ceiling-mounted air conditioner indoor unit 100 of this utility model.

[0071] The indoor unit 100 of a ceiling-mounted air conditioner is the indoor part of the ceiling-mounted air conditioner. The indoor unit 100 is installed indoors and used for heat exchange with the indoor environment. A ceiling-mounted air conditioner may also include an outdoor unit, which is typically installed outdoors and used to transfer heat from the indoor environment to the outside.

[0072] The floor-mounted air conditioner indoor unit 100 has two installation methods: floor-mounted (hereinafter referred to as floor-mounted) and ceiling-mounted (hereinafter referred to as ceiling-mounted). That is to say, the floor-mounted air conditioner indoor unit 100 can be placed on the ground as a floor unit or suspended from the ceiling as a ceiling unit.

[0073] refer to Figure 1 In this embodiment, the ceiling-mounted air conditioner indoor unit 100 includes a body 1. The body 1 is installed indoors, and the body 1 forms the overall appearance of the ceiling-mounted air conditioner indoor unit 100.

[0074] An air duct is formed inside the unit body 1. The air duct is used to house and fix various components in the ceiling-mounted air conditioner indoor unit 100, which can prevent external objects from colliding with the various components inside the unit body 1, thereby improving the reliability of the ceiling-mounted air conditioner indoor unit 100 during transportation or installation.

[0075] refer to Figure 2 In some embodiments of this application, the body 1 may include a rear shell 11. The rear shell 11 is adapted to sit on the ground or be hung on the ceiling.

[0076] refer to Figure 3The body 1 may include an air inlet panel 12. The air inlet panel 12 is connected to the rear shell 11, and an air duct is formed between the air inlet panel 12 and the rear shell 11.

[0077] In some embodiments of this application, reference is made to Figure 3 The body 1 may include an air inlet 121. The air inlet 121 is located on the air inlet panel 12.

[0078] The air inlet 121 is connected to the air duct. The air inlet 121 serves as the entrance for external air to flow into the body 1, allowing indoor air to enter the air duct through the air inlet 121.

[0079] In some embodiments of this application, reference is made to Figure 2 The main body 1 may include an air outlet 14.

[0080] The air outlet 14 is connected to the air duct. The air outlet 14 serves as the outlet for the heat exchange airflow inside the body 1, allowing the airflow in the air duct to flow out through the air outlet 14.

[0081] refer to Figure 4 , Figure 5 In this embodiment, the air outlet 14 can be located at the front of the unit body 1 when the indoor unit 100 of the ceiling-mounted air conditioner is suspended. The air inlet 121 can be located at the rear side of the unit body 1 and near the bottom of the unit body 1 when the indoor unit 100 of the ceiling-mounted air conditioner is mounted, that is, the air inlet 121 can be located at the rear bottom of the unit body 1 when the indoor unit 100 of the ceiling-mounted air conditioner is mounted. When the indoor unit 100 of the ceiling-mounted air conditioner is used, the indoor unit 100 of the ceiling-mounted air conditioner takes in air from the rear bottom and exhausts air to the front.

[0082] The air outlet 14 can be elongated. In particular, the air outlet 14 can be extended along the length of the unit body 1, which improves the aesthetics of the ceiling-mounted air conditioner indoor unit 100.

[0083] In some embodiments of this application, the ceiling-mounted air conditioner indoor unit 100 may include an air inlet shroud 122.

[0084] An air inlet shroud 122 is installed at the air inlet 121 to filter the air and prevent larger impurities from entering the air duct.

[0085] In some embodiments of this application, reference continues to be made to Figure 4 The body 1 has a first inner cavity 192 inside. The air outlet 14 is connected to the first inner cavity 192.

[0086] The body 1 has a second inner cavity 193 inside. The air inlet 121 is connected to the second inner cavity 193.

[0087] The first inner cavity 192 and the second inner cavity 193 are arranged inside the body 1 along a first direction. The first inner cavity 192 and the second inner cavity 193 communicate to form an air duct. The first direction is the width direction of the ceiling-mounted air conditioner indoor unit 100.

[0088] The body 1 may include two side plates 17 that are spaced apart from each other along the length of the body 1. The two side plates 17 form the two ends of the air duct in the length direction of the body 1.

[0089] The two side plates 17 are located on both sides of the air inlet 121. That is, the first inner cavity 192 and the second inner cavity 193 are formed between the two side plates 17.

[0090] The body 1 may include two side covers 18. The two side covers 18 are arranged opposite each other along the length of the body 1, forming two ends along the length of the body 1. The two side covers 18 are respectively connected to two side plates 17, serving a decorative and aesthetic purpose.

[0091] It should be noted that the directions described in the text are based on the direction in which the user faces the ceiling-mounted air conditioner indoor unit during installation. The front side is the side of the ceiling-mounted air conditioner indoor unit facing the user during installation, and the opposite side is the rear side. The left and right sides are distinguished by the direction in which the user faces the ceiling-mounted air conditioner indoor unit during installation.

[0092] When the indoor unit 100 of the air conditioner is installed, the indoor unit 100 of the air conditioner has a top and a bottom. The top and bottom are the two ends in the height direction of the body 1, the left and right ends are the two ends in the length direction of the body 1, and the front and rear ends are the two ends in the width direction of the body 1.

[0093] In some embodiments of this application, the ceiling-mounted air conditioner indoor unit 100 may include a partition 191.

[0094] The partition 191 extends along the length of the body 1 and is disposed inside the body 1 so that the body 1 defines a first inner cavity 192 and a second inner cavity 193 arranged along a first direction.

[0095] In some embodiments of this application, reference continues to be made to Figure 5 The indoor unit 100 of the ceiling-mounted air conditioner may include an indoor heat exchanger 2. The indoor heat exchanger 2 extends along the length of the body 1 and is located in the first inner cavity 192 for heat exchange with the airflow inside the body 1.

[0096] The indoor heat exchanger 2 has end plates at both ends along its length. The end plates can prevent stress concentration in the connection structure of the indoor heat exchanger 2 and improve the structural stability of the indoor heat exchanger 2.

[0097] In some embodiments of this application, the indoor unit 100 of the ceiling-mounted air conditioner may include a heat exchange fan 3.

[0098] The heat exchange fan 3 is installed in the second inner cavity 193 and is used to drive the indoor air outside the body 1 to enter the air duct inside the body 1 through the air inlet. The heat exchange fan 3 drives the air in the air duct to flow along the air inlet 121 toward the air outlet 14.

[0099] When installing 100 indoor units of a ceiling-mounted air conditioner, the heat exchange fan 3 is located below the indoor heat exchanger 2. In the airflow direction within the unit 1, the heat exchange fan 3 is located upstream of the indoor heat exchanger 2.

[0100] When the indoor unit 100 of the ceiling-mounted air conditioner is running, driven by the heat exchange fan 3, indoor air enters the air duct through the air inlet 121. The indoor air in the air duct flows through the indoor heat exchanger 2 for heat exchange. The heat exchanged airflow is discharged to the outside through the air outlet 14, thereby enabling the air conditioner to cool and heat, and play the role of regulating the indoor temperature to achieve the user's comfortable temperature.

[0101] The heat exchanger 3 can be a centrifugal fan. One, two, or more heat exchangers 3 can be installed.

[0102] The heat exchanger 3 may include a volute 31, and a centrifugal air duct is formed inside the volute 31. The volute 31 may be connected to the partition 191.

[0103] The volute 31 may include an air inlet, which is connected to a centrifugal air duct for introducing air into the centrifugal air duct.

[0104] The volute 31 may include an air outlet. The air outlet connects the centrifugal air duct and the first inner cavity 192, and is used to supply air to the first inner cavity 192 through the centrifugal air duct.

[0105] In some embodiments of this application, the centrifugal fan 3 may include a centrifugal impeller 32.

[0106] The centrifugal impeller 32 is located inside the centrifugal air duct. The rotation of the centrifugal impeller 32 drives air to enter the centrifugal air duct inside the volute 31 from the air inlet and then to be discharged through the air outlet. The centrifugal impeller has the characteristics of large air volume, high air pressure and short ventilation time, which is beneficial to increasing the air volume of the indoor unit 100 of the ceiling-mounted air conditioner.

[0107] In some embodiments of this application, the ceiling-mounted air conditioner indoor unit 100 may include a water drip tray 16.

[0108] refer to Figure 4 The water tray 16 is located in the first inner cavity 192 and is positioned below the indoor heat exchanger 2. It is used to collect the condensate dripping from the indoor heat exchanger 2 in the cooling mode.

[0109] When the indoor unit 100 of the air conditioner is installed, the vertical projection of the indoor heat exchanger 2 is located in the water collection tray 16, which ensures that the water collection tray 16 can collect most of the condensate generated by the indoor heat exchanger 2, avoids the condensate from damaging the electrical components of the indoor unit 100, and also prevents the condensate from seeping out of the body 1 and dripping, thus affecting the user experience.

[0110] In some embodiments of this application, the centrifugal fan 3 may include a drive motor. The drive motor is connected to the centrifugal impeller 32 to drive the centrifugal impeller 32 to rotate.

[0111] An air conditioner outdoor unit may include an outdoor unit body. An outdoor heat exchange air duct may be installed inside the outdoor unit body.

[0112] The outdoor unit may include an outdoor air inlet. The outdoor air inlet can connect to an outdoor heat exchange duct. The outdoor air inlet is used to introduce outdoor air into the outdoor heat exchange duct.

[0113] The outdoor unit may include an outdoor air outlet. The outdoor air outlet can be connected to an outdoor heat exchange duct. The outdoor air outlet can be used to exhaust air from inside the outdoor heat exchange duct to the outside of the outdoor heat exchange duct.

[0114] An outdoor unit of an air conditioner may include an outdoor heat exchanger. The outdoor heat exchanger may be located inside an outdoor heat exchange duct.

[0115] An outdoor unit for an air conditioner may include an outdoor fan. The outdoor fan may be installed inside an outdoor heat exchange duct.

[0116] The rotation of the outdoor fan causes outdoor air to enter the heat exchange duct through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the outdoor heat exchange duct through the outdoor air outlet.

[0117] An air conditioner may include a compressor. The compressor is located inside the outdoor heat exchange duct.

[0118] Air conditioners may include a throttling device. The throttling device is used to limit airflow. The throttling device can be provided in the indoor unit or outdoor unit of a ceiling-mounted air conditioner.

[0119] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0120] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges it at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

[0121] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0122] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0123] The evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0124] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0125] In 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 heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0126] refer to Figure 5 In some embodiments, the ceiling-mounted air conditioner indoor unit 100 may include a single air guide vane 15.

[0127] The air guide plate 15 is rotatably connected to the body 1. The air guide plate is set at the air outlet 14 to guide the airflow after heat exchange at the air outlet 14.

[0128] To achieve close-range airflow, the rotation angle of the air guide plate 15 is reduced. When the rotation angle of the air guide plate 15 is smaller, the air outlet 14 becomes smaller, resulting in reduced airflow and affecting the cooling or heating performance. Furthermore, in related technologies, even with a reduced rotation angle of the air guide plate 15, the airflow from the indoor unit of the air conditioner cannot reach the area directly below and to the side of the air outlet 14, leading to poor airflow in these areas. In commercial environments, such as shopping malls and supermarkets, customers located directly beneath a ceiling-mounted air conditioner unit may not feel the airflow, thus impacting user experience and comfort.

[0129] To address the aforementioned technical problems, in some embodiments of this application, reference is made to... Figure 5 , Figure 6 A rotatable guide vane 5 is installed outside the air outlet 14 to guide the airflow from the air outlet 14, changing the airflow field distribution without altering the air volume of the air outlet 14. By adjusting the position of the guide vane 5, large-volume, close-range air delivery can be achieved, satisfying the vertical downward air delivery requirement of the air outlet 14 and increasing user comfort.

[0130] For details, please refer to Figure 5The indoor unit of the ceiling-mounted air conditioner may include two brackets 4, which are spaced apart along the length of the air outlet 14. One end of the bracket 4 is detachably connected to the inside of the unit body 1, and the other end of the bracket 4 extends to the outside of the unit body 1 through the air outlet 14.

[0131] A ceiling-mounted air conditioner indoor unit may include two drive units 6. (Reference) Figure 7 Two drive units 6 are mounted on two brackets 4 respectively. The drive unit 6 has an output shaft 611 extending along the length of the air outlet 14.

[0132] The guide plate 5 extends along the length of the air outlet 14. The guide plate 5 is connected to the two output shafts 611 on the side facing the body 1. The two drive devices 6 drive the guide plate 5 to rotate around the center line of the output shaft 611. The rotating guide plate 5 guides the airflow blown out of the air outlet 14 to change the airflow field distribution.

[0133] In this embodiment, by setting a rotatable air guide plate 15 at the air outlet 14 and a guide plate 5 driven by the driving device 6, the airflow at the air outlet 14 is guided twice. The air guide plate 15 can initially guide the airflow, while the guide plate 5 changes the airflow field distribution by rotating, which can make the air volume more evenly distributed to a wider area. By adjusting the position of the guide plate 5, the air delivery distance can be changed to achieve large air volume short-distance air delivery and long-distance air delivery at the air outlet 14. This solves the problem of no airflow below the air outlet 14 and in a small area on the air outlet side of the air outlet 14 in the prior art, improves the comfort of users under the ceiling-mounted air conditioner, and meets the higher requirements of commercial places such as shopping malls for the air delivery range of air conditioning.

[0134] It should be noted that in this application, the distance between the guide plate 5 and the body 1, the size and shape of the guide plate 5, and the position of the center line of the output shaft 611 of the guide plate 5 can all be adjusted according to actual conditions.

[0135] refer to Figure 8 A support portion 51 is provided on the side of the guide plate 5 facing the body 1. A sleeve 52 is provided at the end of the support portion 51 away from the guide plate 5, and the sleeve 52 is sleeved on the outside of the output shaft 611. A first limiting surface 612 is provided on the outer wall of the output shaft 611, and a second limiting surface 521 adapted to the first limiting surface 612 is provided on the inner wall of the sleeve 52. The second limiting surface 521 cooperates with the first limiting surface 612 to prevent the sleeve 52 from rotating relative to the output shaft 611, and to ensure that the guide plate 5 connected to the output shaft 611 and the sleeve 52 rotates synchronously.

[0136] In this embodiment, the synchronous rotation of the output shaft 611 and the guide plate 5 can be achieved simply by the cooperation of the first and second limiting surfaces 521, without the need for complex mechanical structures or additional power devices, thus reducing manufacturing costs and maintenance difficulties.

[0137] The output shafts 611 of the two drive devices 6 are oriented towards or away from each other, allowing the guide plate 5 to bend outward or inward from the center position, thus enabling quick disassembly of the guide plate 5. This design significantly simplifies the disassembly process, enabling rapid disassembly of the guide plate 5 when it needs to be removed, reducing the disassembly time and workload.

[0138] refer to Figures 9-13 In some embodiments of this application, the end of the bracket 4 away from the body 1 is bent to form a bent portion 41, which extends along the length of the air outlet 14. By providing the bent portion 41, a reliable mounting base is provided for the drive device 6, allowing the drive device 6 to be better mounted on the outside of the body 1.

[0139] refer to Figure 10 The drive unit 6 may include a motor base 62, which is mounted on the bent portion 41.

[0140] The drive unit 6 may include a stepper motor 61, which is mounted on a motor mount 62. The motor mount 62 is mounted on the bend 41, which further enhances the stability of the structure and provides a reliable mounting base for the stepper motor 61. This ensures that the drive unit 6 can accurately and stably drive the guide plate 5 to rotate, thereby achieving effective regulation of the airflow field.

[0141] In some embodiments of this application, one end of the bent portion 41 is provided with an anti-rotation platform 411, and the motor base 62 is provided with an anti-rotation hole 621 adapted to the anti-rotation platform 411. The anti-rotation platform 411 is adapted to pass through the anti-rotation hole 621, which can effectively prevent relative rotation between the motor base 62 and the bracket 4, and ensure that the two remain fixedly connected during operation.

[0142] refer to Figure 11 The anti-rotation platform 411 is provided with a first connecting hole 412 for fastener 8 to be connected. The motor base 62 is provided with a through hole 622 perpendicular to the central axis of the anti-rotation hole 621. When the anti-rotation platform 411 is adapted to be inserted into the anti-rotation hole 621, the fastener 8 is fixedly connected to the first connecting hole 412 through the through hole 622.

[0143] The fastener 8 is fixedly connected to the first connecting hole 412 through the through hole 622, which further enhances the connection strength between the bent part 41 and the motor base 62, making the whole structure more stable.

[0144] In this embodiment, the adaptive connection between the anti-rotation platform 411 and the anti-rotation hole 621, along with the connection and fixation of the fastener 8, enables the motor base 62 to be firmly installed on the bent part 41 of the bracket 4, ensuring the stability and accuracy of the rotation of the guide plate 5 and improving the reliability of the air conditioning air supply regulation.

[0145] Furthermore, a vertical platform 413 is provided between the anti-rotation platform 411 and the bending part 41. The vertical platform 413 is used to restrict the horizontal movement of the motor base 62, which can provide precise positioning for the installation of the motor base 62, so that the motor base 62 can be quickly positioned in the correct position, reducing the adjustment time during the installation process and improving the installation efficiency.

[0146] Continue to refer to Figure 11 In this embodiment, a rotating platform 411 is formed by providing planes at the top and bottom of the bent portion 41. The structure is simple and there is no need to set the rotating platform 411 separately.

[0147] By using the upper and lower planes in conjunction with the vertical platform 413, the displacement of the motor base 62 in the installation direction and circumferential direction can be restricted, providing the motor base 62 with precise positioning and limiting functions, ensuring that the motor base 62 can be accurately aligned with the through hole 622 and the first connecting hole 412 during installation and fixed in the designated position.

[0148] refer to Figure 11 , Figure 13 The stepper motor 61 is mounted on the end of the motor mount 62 away from the bracket 4. The stepper motor 61 has flanges 613 on both sides, and the flanges 613 have first through holes 614.

[0149] The motor base 62 is provided with two fixing holes 623 corresponding to the first through hole 614. The fastener 8 passes through the first through hole 614 and can be fixedly connected in the fixing holes 623, so that the stepper motor 61 can be firmly installed on the motor base 62.

[0150] In some embodiments of this application, reference is made to Figure 14 , Figure 15 The drive unit 6 may include a sealing box 63, which covers the motor base 62 and the stepper motor 61 to protect the stepper motor 61.

[0151] In this embodiment, by setting a sealing box 63, the motor base 62 and the stepper motor 61 can be covered, which plays a role in sealing and protection, preventing dust, debris and other objects from entering the drive device 6 and affecting the normal operation of the stepper motor 61, thus extending the service life of the drive device 6, and also improving the overall appearance of the air conditioner indoor unit.

[0152] The bracket 4 is provided with a mounting part 42 spaced apart from the bending part 41, and the sealing box 63 is fixedly installed on the mounting part 42.

[0153] Continue to refer to Figure 14 In this embodiment, the sealing box 63 is provided with a protrusion 633, and the protrusion 633 is provided with a second through hole 634 for the fastener 8 to pass through. The mounting part 42 is provided with a second connecting hole 421 corresponding to the second through hole 634. The fastener 8 passes through the second through hole 634 and is connected to the second connecting hole 421 so that the sealing box 63 is fixedly installed on the mounting part 42.

[0154] In some embodiments, the sealed box 63 may include a box body 631, which is hollow inside and has an opening. A through hole 6311 is provided on the bottom plate of the box body 631 for the bending portion 41 to pass through. A protrusion 633 is provided on the box body 631.

[0155] The sealed box 63 may include a lid 632, which covers the opening of the box body 631 to seal the internal space of the box body 631.

[0156] When installing the drive device 6, first pass the through hole 6311 on the housing 631 through the bracket 4, leaving the bent part 41 exposed. Then, pass the anti-rotation hole 621 of the motor base 62 through the anti-rotation platform 411. The anti-rotation platform 411 and the rear vertical platform 413 limit the movement. Then, fix the motor base 62 on the bent part 41 using fasteners 8. After the motor base 62 is installed, further install the stepper motor 61 on the motor base 62 using fasteners 8. Then, fasten the cover 632 onto the housing 631. At this time, the position of the sealing box 63 can be adjusted so that the second through hole 634 on the protrusion 633 of the sealing box 63 is aligned with the second connecting hole 421 on the mounting part 42, and then fixed with fasteners 8. This completes the installation of the drive device 6.

[0157] It can be understood that the output shaft 611 of the stepper motor 61 can pass through the cover and out of the sealed box 63 to connect with the guide plate 5.

[0158] In some embodiments of this application, reference is made to Figure 15 The bracket 4 is provided with a connecting part 43 at the end away from the guide plate 5, and the connecting part 43 has an anti-rotation surface 431.

[0159] See Figure 16 The side plate 17 is provided with a flange hole 171 that is adapted to the connecting part 43. The connecting part 43 is adapted to the flange hole 171 and is fixedly connected by the fastener 8.

[0160] In this embodiment, reference Figure 17By using the flanged hole 171 and the anti-rotation surface 431, along with the fastener 8, a detachable and fixed connection between the bracket 4 and the body 1 is achieved, facilitating the installation and removal of the bracket 4. This design greatly improves the product's flexibility and adaptability, allowing users to choose whether to use the large air deflector 5 according to their actual needs, meeting the requirements of different users in different scenarios, and enhancing the user experience.

[0161] Continue to refer to Figure 16 In order to achieve a tight connection between the bracket 4 and the side plate 17, a third connection hole 432 for fastener 8 to be connected is provided at the end of the connection part 43 away from the air duct.

[0162] refer to Figure 18 When installing fastener 8, add mounting pad 7 to the top surface of flange hole 171, and use fastener 8 to pass through mounting pad 7 and fix it in the third connection hole 432.

[0163] By setting the mounting pad 7, a flat and stable support surface can be provided when fixing the bracket 4, increasing the contact area with the top surface of the flange, ensuring that the fastener 8 can be subjected to force evenly, thereby improving the reliability and stability of the connection.

[0164] Understandably, the outer diameter of the mounting pad 7 should be larger than the outer diameter of the flange hole 171 to ensure that it can completely cover the flange hole 171 and provide sufficient support area.

[0165] Of course, in some other embodiments, the fastener 8 may be connected to the connecting portion 43 through the flange hole 171.

[0166] A limiting part 44 is provided on the outer peripheral wall of the bracket 4. The limiting part 44 is located between the bracket 4 and the connecting part 43 to limit the distance that the connecting part 43 extends into the flange hole 171.

[0167] In this embodiment, the limiting part 44 can limit the distance that the connecting part 43 extends into the flange hole 171, ensuring the accuracy of the position of the bracket 4 during the installation of the side plate 17, improving the assembly effect, ensuring a tight connection between the bracket 4 and the side plate 17, thereby improving the assembly quality and reliability of the entire air conditioning indoor unit.

[0168] refer to Figure 16 , Figure 18 The limiting part 44 may include a limiting groove 441, which is recessed on the outer peripheral wall of the bracket 4.

[0169] The limiting part 44 may include a retaining ring 442, which is engaged in the limiting groove 441. The outer diameter of the retaining ring 442 is larger than the outer diameter of the flange hole 171, which can provide additional support and prevent the bracket 4 from over-extending into the flange hole 171.

[0170] refer to Figure 17 During the installation of bracket 4, the connecting part 43 with the anti-rotation surface 431 extends into the flange hole 171 until the retaining ring 442 contacts the side plate 17 to ensure the accurate positioning of bracket 4. At this time, the connecting part 43 cooperates with the flange hole 171 to prevent relative rotation between the two. A mounting pad 7 is added to the top surface of the flange hole 171, and a fastener 8 is used to pass through the mounting pad 7 and fix it in the third connecting hole 432 to realize the installation of bracket 4 on side plate 17.

[0171] An electrical control box 13 is installed inside the main body 1. The electrical control box 13 is located in the space formed between the side cover 18 and the side plate 17, avoiding direct placement in the air duct, thereby reducing the damage to the electrical control box 13 caused by dust, moisture and other pollutants in the air duct.

[0172] The electrical control box 13 contains an electrical control board, which is electrically connected to the electrical components inside the machine body 1 via connecting wires.

[0173] Understandably, the control board is configured to be electrically connected to the compressor, expansion valve, and heat exchange fan mentioned above via connecting wires, so as to control at least the compressor, expansion valve, and heat exchange fan, thereby controlling the operation of the entire indoor unit of the ceiling-mounted air conditioner and realizing the various predetermined functions of the air conditioner.

[0174] In some embodiments of this application, when the indoor unit 100 of the ceiling-mounted air conditioner is hoisted, a plurality of wire clamps 111 are provided at the top of the unit body 1, and the plurality of wire clamps 111 are arranged at preset path intervals.

[0175] refer to Figure 19 The stepper motor 61 has a motor wire 615, which extends sequentially through the corresponding mounting part 42 and bracket 4 to the body 1, and is connected to the electronic control board inside the body 1 via wire clamp 111. The motor wire 615 is fixed to the bracket 4 and the mounting part 42 by wire bundle.

[0176] Further reference Figure 15 The sealed box 63 has a wire hole 635 on its body 631 for the motor wire 615 to pass through. The motor wire 615 coming out of the sealed box 63 can be locked along the mounting part 42 and the bracket 4 with wire ties, then walk upward to the top of the body 1, where it is clamped and limited by multiple wire clamps 111, and then enters the electrical box through the mounting notch at the position of the lifting plate to connect electrically with the control board.

[0177] In this embodiment, the motor wire 615 is fixed by the wire clamp 111 and the wire tie and its routing is arranged so that the wiring of the motor wire 615 is more orderly and the motor wire 615 is prevented from loosening or shifting due to vibration or external force during operation. This achieves stable power supply and signal transmission for the stepper motor 61 and ensures that the drive device 6 can operate accurately according to the instructions of the control board.

[0178] In some embodiments, the wire hole 635 is sealed by sealing cotton 636 to ensure that the sealing box 63 effectively protects the stepper motor 61.

[0179] When the user no longer wishes to use the deflector plate 5, it can also be removed. To remove it, first bend the large deflector plate 5 outward from the middle position and pull it out from the output shaft 611 of the drive unit 6 on both sides; then remove the left and right outer covers, and remove the fasteners 8 of the bracket 4 on the two side plates 17, and remove the bracket 4 and drive unit 6 together. Finally, disconnect the motor terminal corresponding to the motor wire 615 in the electrical box to complete the removal of the deflector plate 5.

[0180] In some embodiments of this application, reference is made to Figure 20 In the initial position, on the cross section perpendicular to the length direction of the body 1, the vertical distance between the top and bottom of the guide plate 5 is H1, and the vertical distance between the top of the guide plate 5 and the rotation axis is H2, where H1 / 4≤H2≤H1 / 3.

[0181] In this embodiment, by reasonably setting H2, the rotation center of the guide plate 5 is located at the upper part of the guide plate 5 in the initial position, which can increase the air supply range of the air conditioner and ensure that the air outlet 14 can cover a wider area.

[0182] It should be noted that in this embodiment, the initial position of the air guide plate 5 is the position of the air guide plate 5 when the indoor unit 100 of the ceiling-mounted air conditioner is in the off state, and the air guide plate 15 closes the air outlet 14 in the off state. Among them, the first side L1 of the air guide plate 5 facing the air outlet 14 is the first side L1, and the second side L2 of the air guide plate 15 that closes the air outlet 14 is the second side L2. When the first side L1 and the second side L2 are parallel, the air guide plate 5 is in the initial position.

[0183] In some embodiments, H1 / 4 ≤ H2. H2 ≤ H1 / 3.

[0184] The distance H2 should not be too large. If it is, the centerline of the output shaft 611 in the initial position will be too close to the bottom of the guide plate 5, and the guide plate 5 will be positioned too high relative to the air outlet 14, affecting the air delivery range, especially in the area directly below and to the side of the indoor unit. To increase the air delivery range and allow the heat exchange airflow to travel further or reach the ground, the ratio of H1 to H2 should be set to be no less than the first parameter value. The first parameter value can be any value between 3 and 3.3. A suitable specific parameter should be selected during the design process. For example, the first parameter value could be 3.

[0185] The distance H2 cannot be too small. If it is too small, the center line of the output shaft 611 in the initial position will be too close to the top of the guide plate 5, which may cause excessive torque when the guide plate 5 rotates, increasing the burden on the drive unit 6 and thus affecting the energy efficiency and service life of the air conditioner. To reduce the burden on the drive unit 6, the ratio of H1 to H2 is set to be no greater than the second parameter value. The second parameter value can be any value between 3.8 and 4. In specific design, a suitable and specific parameter should be selected. For example, the second parameter value can be 4.

[0186] In some embodiments of this application, reference is made to Figure 19 The length of the air outlet 14 is K1, and the length of the guide plate 5 is K2, wherein K1-(50mm)≤K2≤K1+(50mm).

[0187] In this embodiment, the dimensions of the guide plate 5 are reasonably set so that the length of the guide plate 5 is close to the length of the air outlet 14, which can better cover the area of ​​the air outlet 14, so that the airflow is evenly distributed under the action of the guide plate 5, avoiding local airflow that is too strong or too weak, thereby improving the uniformity of indoor temperature.

[0188] It should be noted that the length of the air outlet 14 is the distance between its two ends along its length, and the length of the guide plate 5 is the distance between its two ends along its length. The length directions of the air outlet 14 and the guide plate 5 are the same as the length directions of the body 1.

[0189] In some embodiments, K2 ≥ K1 - (50 mm). K2 ≤ K1 + (50 mm).

[0190] The length of the deflector 5 should not be too long. An excessively long deflector 5 may exceed the effective range of the air outlet 14, causing more vortices and resistance to be generated at the end of the deflector 5, which would reduce the uniformity of airflow and the efficiency of air conditioning. In addition, an excessively long deflector 5 may exceed the aesthetic design range of the unit 1, affecting the overall appearance of the air conditioner and user acceptance.

[0191] For aesthetic purposes and to reduce eddy currents and drag, the length dimension K2 is set to be no greater than the value of the third parameter. The third parameter value can be any value between (K1 + (40mm)) and (K1 + (50mm)). In specific designs, a suitable parameter should be chosen. For example, the third parameter value could be K1 + (50mm).

[0192] The length of the deflector 5 should not be too short. If the deflector 5 is too short, it will not be able to completely cover the air outlet 14, resulting in some airflow not being effectively guided, and the phenomenon of local airflow being too strong or too weak, which will affect the uniformity of indoor temperature.

[0193] To fully guide the airflow after heat exchange and improve cooling and heating efficiency, the length dimension K2 is set to be no less than the third parameter value. The fourth parameter value can be any value between (K1-(50mm)) and (K1-(40mm)). A suitable specific parameter should be selected during the design process. For example, the fourth parameter value could be K1-(50mm).

[0194] The air guide plate 15 is rotatably connected to the body 1 via a rotating shaft. (Continue to refer to...) Figure 20 The bracket 4 is located below the rotating shaft of the air guide plate 15. The vertical distance between the rotating shaft of the air guide plate 15 and the bracket 4 is H4, where H4 > 10mm.

[0195] H4 should not be too small, as this may interfere with the installation of bracket 4. For ease of installation, H4 is set to a value greater than the fifth parameter. The fifth parameter value can be any value between 10mm and 15mm. In specific design considerations, a suitable parameter should be chosen. For example, the fifth parameter value could be 10mm.

[0196] In some embodiments of this application, the indoor unit of a ceiling-mounted air conditioner may include a bracket 4, which is detachably connected to the unit body 1.

[0197] The indoor unit of the ceiling-mounted air conditioner may include at least two drive units 6, which are mounted on the bracket 4. The at least two drive units 6 are located outside the unit body 1 and are spaced apart along the length of the air outlet 14.

[0198] The indoor unit of a ceiling-mounted air conditioner may include a guide vane 5, which extends along the length of the air outlet 14. The side of the guide vane 5 facing the unit body 1 is connected to the output shaft 611 of at least two drive devices 6. The at least two drive devices 6 drive the guide vane 5 to rotate around the centerline of the output shaft 611. The rotating guide vane 5 guides the airflow blown out of the air outlet 14 to change the airflow field distribution. The centerline of the output shaft 611 extends along the length of the air outlet 14.

[0199] In this embodiment, by setting a guide vane 5 outside the air outlet 14, in conjunction with the guide vane 15 at the air outlet 14, the airflow from the air outlet 14 is guided and the flow field distribution is changed. By adjusting the position of the guide vane 5, the air supply needs of different areas can be better met. Especially below the indoor unit of the ceiling-mounted air conditioner, sufficient airflow can be ensured, improving user comfort and meeting the higher requirements of commercial venues such as shopping malls for air supply range. This improves the air supply performance of the indoor unit and the user experience.

[0200] Understandably, the entire drive unit 6 is positioned at the front of the body 1, and the deflector plate 5 is positioned at the front of the bracket 4. When the user stands at the lower front of the body 1 to view it, the deflector plate 5 obscures the drive unit 6 and the support part 51, so the drive unit 6 has little impact on the appearance of the body 1, thus avoiding affecting the aesthetics.

[0201] In this embodiment, by setting a rotatable air guide plate 5, the air supply range can be expanded, especially covering a small area below and to the left of the air outlet 14, improving the user's comfort experience in a commercial environment. By adjusting the position of the air guide plate 5, a large air volume can be delivered at close range to meet the vertical downward air supply requirements of the air outlet 14.

[0202] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.

[0203] For ease of explanation, the above description has been provided in conjunction with specific embodiments. However, the above exemplary discussion is not intended to be exhaustive or to limit the embodiments to the specific forms disclosed above. Various modifications and variations can be obtained based on the above teachings.
