Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an indoor unit and an air conditioner. Background Art

[0002] At present, for the indoor unit of the split-type air conditioner on the market, after the user sends a command to adjust the angle of the air guide plate through the remote control, the air guide plate is set inside the air outlet, and the rotation process is difficult to observe. The user needs to wait for a while and judge whether the angle of the air guide plate is adjusted properly by feeling the air outlet with the skin, which is extremely inconvenient.

[0003] Moreover, since the air guide plate is built-in, its size is limited by the size of the air outlet, resulting in poor air flow guidance effect. For example, the air supply distance is short during cooling, and the hot air rises during heating, which seriously affects the user experience. Summary of the Invention

[0004] The problem solved by the present invention is that the rotation process of the air guide plate of the existing indoor unit is difficult to observe and the air guide effect is poor.

[0005] In order to solve the above problems, the present invention provides an indoor unit, which has the characteristics of visible rotation process of the air guide plate and better air guide effect.

[0006] An embodiment of the present invention provides an indoor unit, including a shell, a drive assembly and a first air guide plate, the shell being provided with an air outlet, the drive assembly being connected to the shell, the first air guide plate being rotatably arranged on the outer wall of the shell and being located above the air outlet, the drive assembly being transmission-connected to the first air guide plate, and being used to drive the first air guide plate to rotate in a vertical plane outside the shell to guide the air out of the air outlet.

[0007] In the indoor unit provided by an embodiment of the present invention, the first air guide plate is rotatably disposed on the outer wall of the housing and is located above the air outlet. Compared to the prior art in which the air guide plate is disposed inside the air outlet, the rotation process of the first air guide plate of the indoor unit provided by this embodiment is visible. Moreover, since the first air guide plate is disposed outside the air outlet, its size is not limited by the size of the air outlet and can be adaptively adjusted to a larger size to enhance the airflow guiding effect. Therefore, the rotation process of the first air guide plate of the indoor unit provided by this embodiment is visible, and the airflow guiding effect is better. In the heating state, the first air guide plate is used to enhance the downward pressure effect of the hot air. In the cooling state, the first air guide plate is used to form an airflow wall effect to achieve long-distance air supply, providing a better user experience.

[0008] In an optional embodiment, a matching groove is provided on the outer wall of the shell at a position corresponding to the position above the air outlet, and a matching rotating shaft is provided on one side of the first air guide plate, and the matching rotating shaft is embedded in the matching groove.

[0009] The mating shaft provided on one side of the first air guide plate is embedded in the mating groove provided on the outer wall of the shell, thereby realizing the rotatable connection between the first air guide plate and the outer wall of the shell. The mating structure is tighter, and the mating shaft is embedded in the mating groove to prevent excessive gaps from being generated between the first air guide plate and the outer wall of the shell, thereby causing the air to flow through and produce condensation water.

[0010] In an optional embodiment, one end of the matching groove is opened at one end of the shell, and the other end of the matching groove extends to the other end of the shell along the horizontal direction.

[0011] In an optional embodiment, a support arm is further provided on the outer wall of the shell, and the support arm extends into the interior of the mating rotating shaft and is rotatably connected to the mating rotating shaft.

[0012] The support arm extends into the interior of the matching shaft and is rotatably connected to the matching shaft. During actual operation, the first air guide plate and the matching shaft rotate, and the support arm supports the matching shaft and the first air guide plate.

[0013] In an optional embodiment, a through hole is opened on the groove wall of the mating groove, one end of the driving assembly is fixed to the interior of the shell, and the other end extends into the mating groove through the through hole and is transmission-connected to the mating shaft to drive the mating shaft to rotate in the mating groove.

[0014] The drive assembly extends from the inside of the shell into the matching groove and is connected to the matching rotating shaft for transmission, thereby hiding the transmission connection structure, improving safety and aesthetics, and saving installation space.

[0015] In an optional embodiment, the drive assembly includes a gear box, a motor and a linkage shaft, one end of the gear box is fixed to the inside of the shell, a gear set is provided in the gear box, the motor is transmission-connected to one end of the gear set, the other end of the gear set extends into the mating groove along with the gear box and is connected to one end of the linkage shaft, and the other end of the linkage shaft is connected to the mating rotating shaft.

[0016] In an optional embodiment, the first air guide plate is a curved plate.

[0017] In an optional embodiment, when the indoor unit is in a shutdown state, the driving assembly drives the first air guide plate to rotate to a position blocking the air outlet.

[0018] In an optional embodiment, when the indoor unit operates in a heating mode from a shutdown state, the driving component drives the first air guide plate to rotate a first angle so that the airflow blown out of the air outlet flows obliquely downward along the first air guide plate.

[0019] When the indoor unit is operating in heating mode, the first air guide plate tilts the airflow blown out of the air outlet downward to pressurize the hot air, prevent the hot air from rising directly, and improve the heating effect.

[0020] In an optional embodiment, when the indoor unit is in a cooling mode from a shutdown state, the driving component drives the first air guide plate to rotate to a second angle.

[0021] When the indoor unit operates in cooling mode, the rotation angle of the first air guide plate is greater than the rotation angle of the first air guide plate in heating mode, ensuring a greater degree of flat blowing of the cold air, increasing the direct blowing length of the cold air, and thus improving the cooling effect.

[0022] The present invention also provides an air conditioner, including the indoor unit described above, the indoor unit including a shell, a drive assembly and a first air guide plate, the shell is provided with an air outlet, the drive assembly is connected to the shell, the first air guide plate is rotatably arranged on the outer wall of the shell and is located above the air outlet, the drive assembly is transmission-connected to the first air guide plate, and is used to drive the first air guide plate to rotate in a vertical plane outside the shell to guide the air out of the air outlet.

[0023] The air conditioner provided by the present invention has an indoor unit whose first air deflector is rotatably mounted on the outer wall of the housing and positioned above the air outlet. Compared to the prior art in which the air deflector is positioned inside the air outlet, the rotation process of the first air deflector of the indoor unit provided by this embodiment is visible. Moreover, because the first air deflector is positioned outside the air outlet, its size is not restricted by the size of the air outlet and can be adaptively adjusted to a larger size to enhance the airflow guidance effect. Therefore, the air conditioner provided by this embodiment has a visible rotation process of the first air deflector, a better airflow guidance effect for indoor airflow, and a better user experience.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic structural diagram of the indoor unit 100 provided in this embodiment. Figure 2 FIG. 1 is a schematic diagram of the exploded structure of the indoor unit 100 provided in this embodiment.

[0035] The indoor unit 100 provided in this embodiment includes a shell 110, a drive assembly 130 and a first air guide plate 150. The shell 110 is provided with an air outlet 111. The drive assembly 130 is connected to the shell 110. The first air guide plate 150 is rotatably arranged on the outer wall of the shell 110 and is located above the air outlet 111. The drive assembly 130 is transmission-connected to the first air guide plate 150 for driving the first air guide plate 150 to rotate in a vertical plane outside the shell 110.

[0036] The first air guide plate 150 is rotatably disposed on the outer wall of the housing 110 and is located above the air outlet 111. Compared to the prior art in which the air guide plate is disposed inside the air outlet 111, the rotation process of the first air guide plate 150 of the indoor unit 100 provided in this embodiment is visible, and the user can clearly observe whether the first air guide plate 150 has been rotated into place. In addition, since the first air guide plate 150 is disposed outside the air outlet 111, its size is not limited by the size of the air outlet 111 and can be adaptively adjusted to a larger size to improve the airflow guidance effect. Therefore, the indoor unit 100 provided in this embodiment has a visible rotation process of the first air guide plate 150 and a better airflow guidance effect, which can significantly improve the user experience.

[0037] Please refer to Figure 2 and Figure 3, Figure 3 FIG. 1 is a schematic structural diagram of the housing 110 .

[0038] A mating groove 113 is provided on the outer wall of the housing 110, corresponding to a position above the air outlet 111. In this embodiment, the mating groove 113 is a semi-cylindrical groove, i.e., its cross-section is semicircular. A mating shaft 160 is provided on one side of the first air deflector 150. The mating shaft 160 engages with the mating groove 113, and the rotational engagement of the mating shaft 160 with the mating groove 113 enables the first air deflector 150 to rotate with the housing 110.

[0039] It should be noted that the shell 110 of the indoor unit 100 is composed of a middle frame and a panel arranged on the surface of the middle frame. The air outlet 111 is actually opened on the middle frame, and the matching groove 113 can be set on the surface of the middle frame or on the surface of the panel. In this embodiment, the matching groove 113 is set at the position where the surface of the middle frame connects with the upper edge of the air outlet 111.

[0040] In this embodiment, one end of the mating groove 113 is formed at one end of the housing 110, and the other end of the mating groove 113 extends horizontally to the other end of the housing 110. That is, the mating groove 113 extends through the housing 110, forming a through-slot. The mating shaft 160 and the mating groove 113 have the same length, meaning that the end walls of the mating shaft 160 are coplanar with the end walls of the mating groove 113.

[0041] A through hole 115 is opened on the groove wall of the mating groove 113. One end of the driving component 130 is fixed inside the shell 110. The other end of the driving component 130 passes through the through hole 115 into the mating groove 113 and is connected to the mating shaft 160 for driving the mating shaft 160 to rotate in the mating groove 113.

[0042] In fact, in this embodiment, the mating shaft 160 is a hollow structure, and the driving assembly 130 directly extends into the mating shaft 160 through the through hole 115 to be transmission-connected with the mating shaft 160 .

[0043] Furthermore, a support arm 117 is provided on the outer wall of the housing 110. The support arm 117 extends into the interior of the mating shaft 160 and is rotatably connected to the mating shaft 160. In actual application, the support arm 117 supports the mating shaft 160 during its rotation in the mating groove 113.

[0044] In this embodiment, there are two drive assemblies 130, each disposed at either end of the mating groove 113. This provides a transmission connection between the two ends of the mating shaft 160 and also supports the two ends of the mating shaft 160. To ensure the support effect of the support arm 117 and the smooth rotation of the mating shaft 160, in this embodiment, the support arm 117 is disposed in the middle of the mating groove 113.

[0045] In this embodiment, the first air deflector 150 is an arc-shaped plate. The first air deflector 150 includes two long sides and two short sides that are arranged opposite each other. The two long sides intersect and connect end-to-end with the two short sides along the periphery of the first air deflector 150. The two long sides are parallel to each other and extend in a straight line, while the two short sides are parallel to each other and extend in a curved line. One of the two long sides is connected to the outer wall of the mating shaft 160, and the length of the long side is the same as the length of the mating shaft 160. That is, the end surfaces of the mating shaft 160 are coplanar with the two short sides, and the extension direction of the mating shaft 160 is parallel to the extension direction of the long sides.

[0046] The long side of first air deflector 150 is equal in length to mating shaft 160, which in turn is equal in length to mating groove 113. Mating groove 113 extends horizontally through the surface of housing 110. As can be seen, the fit between mating shaft 160 and mating groove 113 creates a minimal gap between first air deflector 150 and the surface of housing 110, ensuring a tight fit and preventing the formation of condensation.

[0047] In this embodiment, the long side of the first air guide plate 150 is perpendicular to the plane where the short side is located, that is, the first air guide plate 150 is substantially rectangular.

[0048] See also Figure 4 , Figure 4 It is a schematic diagram of the connection structure between the driving assembly 130 and the matching rotating shaft 160.

[0049] A mounting plate 165 is provided in the mating rotating shaft 160. The driving assembly 130 includes a gear box 131, a motor 133 and a linkage shaft 135. One end of the gear box 131 is fixed to the inside of the housing 110. A gear set is provided in the gear box 131. The motor 133 is provided inside the housing and is transmission-connected to one end of the gear set. The other end of the gear set extends into the mating groove 113 along with the gear box 131 and is connected to one end of the linkage shaft 135. The other end of the linkage shaft 135 is connected to the mounting plate 165.

[0050] In practice, one end of the linkage shaft 135 extends into the gear box 131 and connects to the gear set, while the other end of the linkage shaft 135 is connected to the mounting plate 165. The linkage shaft 135 is used to transmit the torque of the gear set to the mounting plate 165, and the mounting plate 165 is used to transmit the torque transmitted by the linkage shaft 135 to the mating shaft 160, so that the mating shaft 160 rotates within the mating groove 113, thereby driving the first air guide plate 150 to rotate within the vertical plane, thereby guiding air at different angles to the air outlet 111.

[0051] See also Figure 5 , Figure 5 FIG. 1 is a cross-sectional view of the indoor unit 100 provided in this embodiment in a shutdown state.

[0052] In the indoor unit 100 provided in this embodiment, when the unit is turned off, the driving assembly 130 drives the first air guide plate 150 to rotate to a position that blocks the air outlet 111. Therefore, in the turned off state, the first air guide plate 150 completely blocks the air outlet 111 from the outside of the housing 110.

[0053] See also Figure 6 , Figure 6 FIG2 is a cross-sectional view of the indoor unit 100 provided in this embodiment in the heating mode.

[0054] When the indoor unit 100 is switched from the shutdown state to the heating mode, the driving assembly 130 drives the first air guide plate 150 to rotate at a first angle so that the airflow blown out of the air outlet 111 flows obliquely downward along the first air guide plate 150 .

[0055] Since the air guide plate is arranged inside the air outlet 111, its air guiding size is limited by the size of the air outlet 111, and its guiding effect on the air outlet is limited. When the indoor unit 100 is operating in heating mode, the hot air blown out from the air outlet 111 will immediately float upward, causing a large amount of hot air to gather above the room, resulting in the user's head being hot and legs being cold. In this embodiment, the first air guide plate 150 is arranged outside the shell 110, and its size is not limited by the size of the air outlet 111, which has a better effect of pressing the hot air downward. In addition, the first air guide plate 150 is a curved plate with its ends drooping, which has a better effect of pressing the hot air downward.

[0056] See also Figure 7 , Figure 7 FIG. 1 is a cross-sectional view of the indoor unit 100 provided in this embodiment in the cooling mode.

[0057] When the indoor unit 100 is in a cooling mode from a shutdown state, the driving assembly 130 drives the first air guide plate 150 to rotate to a second angle, which is greater than the first angle.

[0058] In this embodiment, the first air guide plate 150 is disposed outside the housing 110. Its size is not limited by the size of the air outlet 111 and can be configured longer, ensuring that the cold air can be blown farther, thereby improving the cooling effect. In cooling mode, this is more conducive to long-distance transmission of cold air.

[0059] In summary, in the indoor unit 100 provided in this embodiment, the rotation process of the first air deflector 150 is visible during actual use, making it easier for the user to quickly adjust the first air deflector 150 to the desired angle. Furthermore, because the first air deflector 150 is located outside the air outlet 111, its size is not limited by the size of the air outlet 111 and can be adaptively adjusted to a larger size, thereby improving the air guiding effect.

[0060] In addition, this embodiment also provides an air conditioner, including the aforementioned indoor unit 100. Since the rotation angle of the air guide plate of the indoor unit 100 is visible and the air guiding effect is better, the air conditioner provided by this embodiment has a better user experience.

[0061] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
