Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] Traditional central air conditioning (such as ducted systems) mainly requires users to install ceiling installations during home renovation. These ceilings occupy home space, making the living space appear very small. Moreover, traditional central air conditioning uses a horizontal air outlet method. Due to limitations in unit structure and installation location (such as light troughs), and the inability of air guide plates to effectively guide airflow, hot air tends to rise in heating mode, resulting in slow heating and poor comfort.

[0072] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0073] like Figures 1 to 31The air conditioner indoor unit shown includes: a housing 1, on which a first air vent 2 and a second air vent 3 are provided, the first air vent 2 facing a first direction and the second air vent 3 facing a second direction; an air duct 101, which is detachably connected to the first air vent 2; and a moving mechanism, which is disposed within a first structure inside the room, and the housing 1 is detachably disposed within the first structure under the action of the moving mechanism, that is, the indoor unit can be inserted into or slid out of the first structure under the action of the moving mechanism, thereby facilitating the disassembly of the air conditioner indoor unit. At the same time, the air duct 101 is used to guide the air from the first air vent 2, so that the air outlet position of the air conditioner indoor unit is different when cooling and when heating, so that cold air (when cooling) or hot air (when heating) can be evenly covered to the entire room, increasing the heat exchange efficiency of the air conditioner indoor unit.

[0074] The first structure has a guide rail 102, and the housing 1 has a sliding groove 103. The sliding groove 103 and the guide rail 102 cooperate to form the moving mechanism; or the housing 1 has a guide rail 102, and the first structure has a sliding groove 103. The sliding groove 103 and the guide rail 102 constitute the moving mechanism. Through the cooperation of the sliding groove 103 and the guide rail 102, the housing 1 can slide relative to the first structure, thereby facilitating the movement of the indoor unit.

[0075] The moving mechanism also includes a shock-absorbing mechanism. The guide rail 102 is disposed within the first structure through the shock-absorbing mechanism; or the guide rail 102 is disposed on the housing 1 through the shock-absorbing mechanism. The shock-absorbing mechanism reduces the transmission of vibration of the indoor unit and effectively reduces noise.

[0076] The first structure includes a wardrobe 104. When using the wardrobe 104, people mainly use the lower two-thirds of the area. The top area of ​​the wardrobe 104 is generally used to store items that are not used for a long time, or even left idle (without storing items), resulting in low space utilization of the wardrobe 104. Therefore, this technical solution has a pre-set installation groove in the wardrobe 104. The housing 1 is inserted into or removed from the installation groove under the action of the moving mechanism, thereby embedding the air conditioner indoor unit into the wardrobe 104. This increases the utilization rate of the wardrobe 104 and overcomes the technical prejudice that the air conditioner indoor unit can only be installed in the ceiling in the prior art, reducing the space occupied by the indoor unit.

[0077] The duct 101 is installed inside the wardrobe 104. By reducing the depth of a portion of the wardrobe 104, the duct 101 reduces its footprint in the room. Since the duct 101 is a flat tube, the depth it occupies is not significant and will not affect normal use. The first end of the duct 101 extends into the mounting groove and connects with the first air outlet 2 of the indoor air conditioning unit embedded in the mounting groove, thus facilitating the airflow from the first air outlet 2. Meanwhile, the second end of the duct 101 connects to the outside of the wardrobe 104, allowing the first air outlet 2 to connect with the room, facilitating the intake or exhaust of air into the room.

[0078] The wardrobe 104 has a first air inlet and a second air inlet and an outlet. The second air inlet and outlet is located below the first air inlet and outlet, and the first air inlet and outlet is connected to the first air outlet 2. The second air inlet and outlet is connected to the first air outlet 2 through the air duct 101. That is, the first air inlet and outlet and the second air inlet and outlet are set to have a certain height difference, so that the cold air during cooling and the hot air during heating flow according to their own properties, thereby increasing the indoor heat exchange efficiency. Preferably, the first air inlet and outlet is located at the top edge of the wardrobe 104, and the second air inlet and outlet is located at the bottom edge of the wardrobe 104.

[0079] The indoor unit of the air conditioner also includes an air vent grille, which is provided at the first air inlet / outlet and / or the second air inlet / outlet.

[0080] As another embodiment, when the duct 101 cannot be installed in the first structure, in order to avoid the duct 101 being directly exposed to the room and posing a safety hazard, the duct 101 is installed in the second structure inside the room. The first end of the duct 101 extends into the first structure and communicates with the first air outlet 2, and the second end of the duct 101 protrudes from the second structure and communicates with the room, thereby achieving a concealed configuration of the duct 101.

[0081] The second structure includes walls.

[0082] In another embodiment, the duct 101 is directly exposed indoors, and preferably, the duct 101 is attached to a wall.

[0083] The indoor unit of the air conditioner further includes: a heat exchanger disposed within the housing 1; and a fan disposed within the housing 1, wherein the fan has a first state in which gas passes sequentially through the first air outlet 2, the heat exchanger, and the second air outlet 3, and a second state in which gas passes sequentially through the second air outlet 3, the heat exchanger, and the first air outlet 2.

[0084] When the fan is in the first state, the first air inlet 2 serves as the air inlet and the second air inlet 3 serves as the air outlet. When the fan is in the second state, the first air inlet 2 serves as the air outlet and the second air inlet 3 serves as the air inlet.

[0085] like Figure 6 and Figure 7 The fan is rotatably mounted inside the housing 1, allowing the fan to freely switch between the first state and the second state. Figure 6 This is a structural diagram of the fan in its first state. Figure 7 This is a structural schematic diagram of the fan in its second state.

[0086] In some embodiments, the outlet of the fan is tilted relative to the horizontal direction. The outlet of the fan is tilted upward or downward relative to the horizontal direction.

[0087] The indoor unit of the air conditioner also includes a support part for supporting the fan. The fan is spherical or spherical in shape. The support part is provided with a mounting cavity adapted to the fan. The fan is rotatably disposed in the mounting cavity, thereby facilitating free switching between the first state and the second state.

[0088] In some embodiments, there are multiple mounting cavities, each corresponding to a fan. The fan is installed in a corresponding mounting cavity, and the multiple mounting cavities are independent of each other; adjacent mounting cavities are spaced apart.

[0089] In some embodiments, multiple mounting cavities are interconnected, which helps to reduce noise from the indoor unit of the air conditioner during operation.

[0090] In this embodiment, the fan is a mixed-flow fan. Furthermore, the mixed-flow fan can overcome the disadvantages of centrifugal fans (small air volume and large size), axial fans (high noise), and cross-flow fans (large size), and can ensure a balance between air volume, static pressure, and size.

[0091] In some embodiments, the fan and the motor that drives the fan are integrated. That is, the motor and the fan are a combined product assembled into one unit.

[0092] The support portion 6 includes a first support portion 61 and a second support portion 62 disposed opposite to the first support portion 61; the mounting cavity 63 includes a first recess on the surface of the first support portion 61 facing the second support portion 62 and a second recess on the surface of the second support portion 62 facing the first support portion 61.

[0093] Figure 11 and Figure 12 A schematic diagram of the structure of the fan 5 in this embodiment is shown, combined with Figures 9 to 12As shown, the fan 5 is provided with a first steering shaft 51, and the fan 5 is configured to rotate around the rotation center of the first steering shaft 51. The bearing part 6 is provided with a first mounting hole for mounting the first steering shaft 51. The first mounting hole is formed by a first groove 64 on the surface of the first bearing part 61 facing the second bearing part and a second groove 65 on the surface of the second bearing part 62 facing the first bearing part 61.

[0094] like Figure 10 As shown, the first groove 64 includes a steering shaft mounting groove 64a and a bearing mounting groove 64b.

[0095] The fan 5 is also provided with a second steering shaft 54, which is coaxial with the first steering shaft 51. The support portion 6 is provided with a second mounting hole for mounting the second steering shaft. The fan 5 is rotatably mounted in the mounting cavity 63 of the support portion 6 via the first steering shaft 51 and the second steering shaft 54. The second mounting hole is formed by a third groove 66 on the surface of the first support portion 61 facing the second support portion and a fourth groove 67 on the surface of the second support portion 62 facing the first support portion 61.

[0096] The first steering shaft 51 and the second steering shaft 54 ​​are coaxially arranged and respectively located at both ends of the fan 5.

[0097] In some embodiments, the fan 5 can rotate about a vertical axis of rotation to switch between a first orientation and a second orientation. The axial directions of the first steering shaft 51 and the second steering shaft 54 ​​are aligned with the vertical direction. The first steering shaft 51 is located at the top of the fan 5, and the second steering shaft 54 ​​is located at the bottom of the fan 5.

[0098] like Figure 8 As shown, the first steering shaft 51 is mounted in the first mounting hole via the first bearing 91, and the second steering shaft 54 ​​is mounted in the second mounting hole via the second bearing 92.

[0099] like Figure 9 As shown, a central hole 53 is provided on the first steering shaft 51. The indoor unit of the air conditioner also includes a cable 52 connected to the fan 5, which passes through the central hole 53. The cable 52 includes a power supply cable for supplying power to the fan and a control cable for controlling the drive of the fan 5.

[0100] The indoor unit of the air conditioner also includes a drive unit for driving the fan 5 to rotate to switch between a first orientation and a second orientation. Figure 5 A schematic diagram of the drive unit in this embodiment is shown.

[0101] Combination Figures 8 to 12As shown, the drive unit includes a first gear 8 connected to the fan 5, a second gear 11 meshing with the first gear 8, and a drive motor 12 for driving the second gear 11. Optionally, the second gear 11 is mounted on the shaft of the drive motor.

[0102] The axis of the first gear 8 coincides with the rotation axis of the fan 5. For example... Figure 8 , 11 As shown in Figure 12, the first gear 8 is located at the bottom of the fan 5 and is mounted on the second steering shaft 54.

[0103] In some embodiments, drive motors 12 are provided in a one-to-one correspondence with fans 5. The drive motors 12 are connected to the first gear 8 connected to the corresponding fans 5.

[0104] In some embodiments, such as Figure 13 As shown, a drive motor 12 is connected to a first gear 8 on at least two fans 5 to drive the at least two fans 5 to rotate. Optionally, the drive motor 12 is connected to the first gear 8 on at least two fans 5 via a gear transmission assembly.

[0105] In this embodiment, the fan 5 and the drive motor 12 are arranged alternately. The drive motor 12 is connected to the first gear 8 on the two adjacent fans 5. The drive motor 12 is equipped with a second gear 11, which meshes with the first gear 8 on the two fans 5 located on its two sides respectively.

[0106] like Figure 13 As shown, in this embodiment, the drive unit is located at the bottom of the fan 5.

[0107] Figure 14 A schematic diagram of an optional implementation of this embodiment is shown. In this embodiment, the drive unit is located at the top of the fan 5, so that the drive unit is away from the humid environment located at the bottom of the indoor unit of the air conditioner, which helps to avoid corrosion of the drive unit and improve the service life of the components of the drive unit.

[0108] In this embodiment, when the fan 5 rotates in the first direction and switches to the second direction, the motor 5 needs to rotate 180 degrees.

[0109] In some embodiments, the drive unit includes a drive motor 12 and a belt drive assembly for drivingly connecting the drive motor 12 to the fan 5. The belt drive assembly includes a first pulley mounted on the drive motor 12 and a second pulley mounted on the fan 5.

[0110] In some embodiments, the indoor unit of the air conditioner further includes an elastic member connected between the fan 5 and the support portion 6, and configured to push the fan 5 toward a first orientation or a second orientation. The drive unit of the indoor unit is configured to overcome the elastic force of the elastic member to switch the orientation of the fan 5. The drive unit includes one of a cylinder, a hydraulic cylinder, and a linear motor.

[0111] In some embodiments, the drive unit further includes a first magnetic body mounted on the fan 5 and a second magnetic body mounted on the support unit 6. The first magnetic body and the second magnetic body have different magnetisms, so that the fan 5 moves under the attraction of the first magnetic body and the second magnetic body, thereby changing the orientation of the fan 5; or, the first magnetic body and the second magnetic body have the same magnetism, so that the fan 5 moves under the repulsive force of the first magnetic body and the second magnetic body, thereby changing the orientation of the fan 5.

[0112] In some embodiments, the indoor unit of the air conditioner further includes a guide section, which includes a guide rail 102 and a moving component that can move along the guide rail 102. One of the moving component and the guide rail 102 is mounted on the fan 5, and the other is mounted on the support section 6.

[0113] The indoor unit of the air conditioner in this embodiment also includes a limiting part for limiting the angle of rotation of the fan 5 relative to the housing 1, combined with Figure 8 , 9 and Figure 12 As shown, the limiting part includes a moving part 10 that rotates with the fan 5 and a blocking part 68 for blocking the movement of the moving part 10. The blocking part 68 is disposed in the path of the moving part 10 rotating with the fan 5. When the moving part 10 rotates to the blocking part 68, the moving part 10 is blocked by the blocking part 68, thereby the blocking part 68 can limit the rotation angle of the fan 5.

[0114] The blocking component 68 includes a first blocking component and a second blocking component. The first blocking component and the second blocking component are located at the two ends of the movement path of the moving component 10 as it rotates with the fan 5. The first blocking component and the second blocking component are 180 degrees apart in the circumferential direction at the rotation center of the fan 5, so that the rotation angle of the fan 5 is 0 to 180 degrees.

[0115] In some embodiments, the indoor unit of the air conditioner further includes a position detection component for checking whether the fan 5 has rotated to a predetermined position. The position detection component includes a micro switch or a position sensor. The micro switch or position sensor is disposed on the path of the fan 5 rotation, and after the fan 5 rotates to the predetermined position, the micro switch and the position sensor send corresponding signals.

[0116] The air inlet and air outlet of the fan 5 are located at opposite ends of the fan. After the fan 5 rotates 180 degrees, the air inlet and air outlet of the fan 5 reverse their directions, thereby allowing the fan 5 to switch between the first orientation and the second orientation.

[0117] In some embodiments, the rotation angle range of the fan 5 can be extended from 0 to 360 degrees, taking into account the arrangement of the heat exchangers.

[0118] In some embodiments, the fan 5 includes a housing 1 and fan blades disposed within the housing 1, with both the air outlet and air inlet of the fan 5 located on the housing 1. The fan 5 also includes a sound-insulating material layer disposed on the surface of the housing 1. The sound-insulating material layer includes at least one of noise-reducing foam and plush material. Optionally, the sound-insulating material layer is disposed on the inner surface of the housing 1.

[0119] Combination Figure 5 and Figure 8 As shown, the indoor unit of the air conditioner includes multiple fans 5 arranged side by side, and each fan 5 is equipped with a first gear 8. Optionally, the multiple first gears 8 are all connected to the second gear 11 for transmission.

[0120] like Figure 6 and 7 As shown, heat exchanger 4 includes a first heat exchanger and a second heat exchanger. The first and second heat exchangers are arranged in a V-shape, with the tip of the V-shape facing the fan 5. This heat exchanger ensures that the high-speed air at the outermost part of the fan 5 has a sufficiently long airflow space, reducing fan airflow losses.

[0121] The indoor unit of the air conditioner also includes a water receiving component 7 located below the heat exchanger, which is used to receive condensate generated on the heat exchanger 4.

[0122] In some embodiments, the blower 5 is inclined relative to the water receiving component 7. A space is provided above the blower 5 for laying cables 52 connected to the blower 5. The cables 52 include a first cable and a second cable with a different direction from the first cable to prevent stress concentration on the cables when the blower 5 changes direction.

[0123] In some embodiments, the indoor unit of the air conditioner is installed on the wall between two adjacent rooms and can be selectively directed to one of the two rooms.

[0124] In some embodiments, the first air vent 2 is disposed on the bottom wall of the indoor unit of the air conditioner, and the second air vent 3 is disposed on the side wall of the indoor unit of the air conditioner, the side wall being perpendicular to the bottom wall on which the first air vent 2 is disposed.

[0125] The indoor unit of the air conditioner achieves downward airflow through the duct 101 embedded in the wall. Optionally, the side airflow is directly blown out from the second air outlet 3, and the first air outlet 2 is connected to the air outlet on the wall through the duct 101. The purpose of connecting the duct 101 in the wall to the air outlet on the wall is to reduce the resistance when the air returns from the downward air outlet.

[0126] In some embodiments, an air guide plate is provided at the air outlet, and the air guide plate is provided with micropores.

[0127] In some embodiments, a humidification device is provided on the air vent; optionally, the humidification device includes an ultrasonic humidification device.

[0128] The air outlet can be installed in the wardrobe 104 or any other cabinet to prevent people from accidentally bumping into it. In some embodiments, a fan is also installed in the air duct 101 in the wall.

[0129] In this embodiment, the fan 5 is a mixed-flow fan. Mixed-flow fans are small in size and have a circular shape. The fan reversal does not increase the space volume of the indoor unit of the air conditioner. The high-speed operation of the fan can significantly reduce the size of the fan and further reduce the overall size of the unit. The air outlet of the mixed-flow fan is circular. Compared with traditional centrifugal fans, the air outlet basically covers the upper and lower surfaces of the heat exchanger. The circular air outlet is more uniform and significantly reduces the uneven distribution of air volume on the surface of the heat exchanger, thereby reducing the uneven distribution of temperature on the surface of the heat exchanger and thus providing a better user experience.

[0130] Due to the use of mixed-flow fans, the air velocity on the heat exchanger surface is more uniform. Under the same air volume and windward area, there will be no areas of high air velocity on the heat exchanger surface. Since the air velocity on the heat exchanger surface is improved, and guide fluids are installed at both the unit's outlet and return air points, the unit's outlet and return air resistance is further reduced. More importantly, this technical solution has only one fan system, unlike previous solutions where another fan became a source of resistance or a new source of noise for the unit. Therefore, the unit's noise can be significantly reduced.

[0131] The “V”-shaped heat exchanger is arranged at the air outlet of the mixed flow fan, which makes the airflow distribution on the heat exchanger surface more uniform, the heat exchange effect better, and can significantly reduce the volume of the heat exchanger; save materials and reduce the unit cost; at the same time, because the air velocity on the heat exchanger surface is uniform, the temperature distribution at the unit outlet is more uniform, and the minimum air outlet temperature is significantly higher than that of previous fan designs, reducing the risk of condensation in the unit.

[0132] Mixed-flow fans (unlike existing technologies that use centrifugal fans, cross-flow fans, and axial fans) are small in size but have a large air volume, enabling large air volume output with a small fan size. Because the structure of a mixed-flow fan is approximately "spherical," it does not require a large volute like centrifugal fans or a vortex structure like cross-flow fans, which require a large unit space to rotate. This technology does not require much additional unit space to rotate the fan (virtually none); therefore, it can significantly reduce the unit size compared to previous solutions.

[0133] According to another aspect of the present invention, this embodiment also provides an air conditioner including the above-described indoor unit. In some embodiments, the indoor unit is a ducted air conditioner.

[0134] Example 2

[0135] Figure 15 A schematic diagram of the structure of the indoor unit of the air conditioner in this embodiment is shown. The difference between this embodiment and Embodiment 1 is that the first heat exchanger 41 and the second heat exchanger 42 of the heat exchanger 4 are arranged in a V-shape, and a flow guiding component 13 is provided on the angle bisector of the first heat exchanger 41 and the second heat exchanger 42. The flow guiding component 13 extends along the direction of the angle bisector of the first heat exchanger 41 and the second heat exchanger 42.

[0136] By setting the flow guide component 13 between the first heat exchanger 41 and the second heat exchanger 42, the airflow from the first heat exchanger 41 and the airflow from the second heat exchanger 42 can be separated, avoiding the convergence of the airflow from the first heat exchanger 41 and the airflow from the second heat exchanger 42 to generate vortices. After the vortices are reduced, the impact on the airflow volume can be reduced, noise can be reduced, and the user experience can be improved.

[0137] In some embodiments, a flow guiding component is also provided in the flow channel inside the indoor unit.

[0138] Example 3

[0139] Figure 16 This diagram shows a structural schematic of the fan and support of the indoor unit of the air conditioner in this embodiment; Figure 17 A schematic diagram of the internal structure of the support portion of the air conditioner indoor unit in this embodiment is shown; Figure 15 A cross-sectional structural schematic diagram of the indoor unit of the air conditioner in this embodiment is shown; Figure 16 A schematic diagram of the fan structure of the indoor unit of the air conditioner in this embodiment is shown.

[0140] Combination Figures 16 to 19 As shown, the difference between this embodiment and embodiment one is that the drive unit used to drive the fan 5 to rotate so that the air outlet of the fan 5 can switch directions is set one-to-one with the fan 5.

[0141] The orientation of the air outlets of multiple fans 5 can be controlled independently. By fine-tuning the orientation of the air outlets, the air outlets of the indoor unit of the air conditioner can be made uniform, and the airflow through the heat exchanger 4 can be distributed evenly.

[0142] The drive unit includes a drive motor 12, a third gear 14 mounted on the drive motor 12, and a fourth gear 15 fixed relative to the support unit 6. The drive motor 12 is fixed relative to the fan 5. The third gear 14 meshes with the fourth gear. During the process of the drive motor 12 driving the third gear 14 to rotate, the third gear 14 rotates around the fourth gear 15, thereby driving the fan 5 to rotate so that the air outlet of the fan 5 switches its direction.

[0143] Optionally, the diameter of the fourth gear 15 is larger than the diameter of the third gear.

[0144] In this embodiment, the drive motor 12 can drive the fan 5 to rotate with a small torque to switch the direction of the fan 5's air outlet, which helps prevent the transmission components from being damaged due to excessive torque and helps improve the service life and reliability of each component.

[0145] In this embodiment, the drive unit is located at the top of the fan 5, so that the drive unit is away from the humid environment at the bottom of the air conditioner indoor unit, which helps to avoid corrosion of the drive unit and improve the service life of each component of the drive unit.
