Description

Technical Field

The present disclosure relates to the technical field of air conditioning, in particular to an air conditioner.

Background Art

The air conditioner refers to a device that uses manual means to adjust and control parameters of ambient air in buildings or architectures, such as temperature, humidity, and flow rate. The air conditioners are mostly provided with an air deflector. The air deflector is connected to a driving box of the air conditioner, so as to drive the air deflector to rotate to form different opening angles.
At present, for a casing of an indoor unit of an air conditioner on the market, a structure for installing the air deflector is provided inside an air outlet, so that in practical applications, a rotation process of the air deflector is invisible, and after sending an instruction for adjusting an angle of the air deflector through a remote controller, a user needs to judge whether the angle of the air deflector is adjusted in place through feeling of skin about the outgoing air coming out, which is quite inconvenient. Moreover, since the structure of the casing for installing the air deflector is provided inside the air outlet, after being installed, the air deflector cannot be tightly fitted with an outer surface of the casing, and there is a relatively large gap, then in an actual operation process, the outgoing air is likely to flow through the gap between the air deflector and the outer surface of the casing and condenses.
In addition, when the air conditioner supplies air, air having undergone heat exchange is usually blown by a wind wheel from the air outlet into room. In a heating mode, hot air is blown out from the air outlet of the air conditioner, and due to relatively small density of the hot air, the hot air is easy to directly float to an upper space in the room after leaving the air outlet, and can hardly reach the ground. In this way, it is easy to cause the problem of uneven distribution of cold and hot when the air conditioner is used for heating, and users' comfort is reduced.
Besides, in the prior art, in the rotation process of the air deflector, the air deflector will collide with the casing, thus causing wear, damage, and abnormal noises of the air deflector.

Summary

In order to solve the above problems existing in the prior art, the present disclosure provides an air conditioner, including a casing and an air deflector, wherein the casing is provided with an air outlet, an assembly groove is recessed on an outer wall of the casing, the assembly groove is provided with a rotation region, the air deflector includes a mounting part and an air guiding part, wherein the air guiding part is connected to the mounting part, for guiding an air outlet direction of the air outlet, and the mounting part is connected in the assembly groove, so that the air deflector is rotatably connected to the outside of the air outlet of the casing in the rotation region provided for the assembly groove. In the rotation region corresponding to the assembly groove, the air deflector can be driven by other driving devices to rotate back and forth, and also can stay at any position in the rotation region. Since the air deflector is mounted in the assembly groove on the outer wall of the casing, the whole air deflector is within a visible range of users, thus a rotation process of the air deflector is visualized.
Optionally, the assembly groove is located above the outside of the air outlet, and is parallel to a length direction of the air outlet. As the assembly groove is located above the air outlet, after the air deflector is mounted in the assembly groove, when the air conditioner is heating, hot air blown out from the air outlet can flow under the guidance of the air deflector, and being blocked by the air deflector, hot air blown out from the air outlet will not directly float upwards to the upper space after leaving the air outlet, thereby improving the heating uniformity degree of the upper space and the lower space, further improving the heating effect of the air conditioner, and enhancing the user's using comfort. When the air conditioner is cooling, no matter for a vertical air conditioner or a hanging air conditioner, as the air outlet of the indoor unit is arranged at a relatively high place in the room, when the air deflector has a relatively large opening angle, under the guidance of the air deflector, cold air blown out from the air outlet will not directly flow downwards to the lower space after leaving the air outlet, thus promoting a cooling uniformity degree of the upper space and the lower space, further improving cooling effect of the air conditioner, and enhancing the user's using comfort.
Optionally, the assembly groove is joined with an upper edge of the air outlet. The longer a distance between the assembly groove and the air outlet is, the lower the utilization rate of air guiding effect of the air deflector is. By joining the assembly groove with the upper edge of the air outlet, the utilization rate of the air deflector can be maximized, thus avoiding a too large dimension of the air deflector, and saving the production costs. The assembly groove is parallel to an extending direction of the air outlet. In an actual operation process, each part of the air deflector connected to the assembly groove can have the air guiding effect, thus further improving the utilization rate of the air deflector.
In an optional embodiment, the assembly groove extends along a horizontal direction. By making the assembly groove extend along the horizontal direction, that is, the upper edge of the air outlet also extends along the horizontal direction, an aesthetic degree after the air deflector is assembled is improved.
Optionally, a cross section of the mounting part is in an arc shape, and a cross section of the assembly groove is adapted to the mounting part, so that the mounting part and the assembly groove are arranged concentrically, and a gap between the mounting part and the assembly groove is as small as possible, thus preventing condensation on the outer wall of the casing.
In an optional embodiment, the assembly groove has one end opened on an end wall of one end of the casing in the horizontal direction, and the other end extending to an end wall of the other end of the casing in the horizontal direction. The two ends of the assembly groove are respectively located on the end walls of the two ends of the casing in the horizontal direction, i.e., the assembly groove penetrates through the casing in the horizontal direction, ensuring that after the air deflector is mounted in the assembly groove, the air deflector can be completely and tightly fitted with the outer wall of the casing in the horizontal direction, thus avoiding generation of a blank area and a too big gap, and improving anti-condensation effect.
In an optional embodiment, a recessed region is recessed on the outer wall of the casing, the air outlet is opened in the recessed region, and the recessed region is configured to be fitted with the air deflector. In a power-off state, the air deflector is embedded into the recessed region to realize fitting with the recessed region, realize storage of the air deflector, prevent the air deflector from protruding from the outer wall of the casing in the power-off state, and improve the aesthetic degree.

Optionally, the air deflector includes an outer plate and an inner lining plate, the inner lining plate and the outer plate are stacked and spliced, wherein there is a gap between the outer plate and the inner lining plate, and the inner lining plate is configured to guide airflow blown out from the air outlet of the air conditioner, and the outer plate can be configured to decorate and strengthen structural strength of the air deflector.
Optionally, the outer plate includes a first arc plate, the inner lining plate includes a second arc plate, the first arc plate is connected to the second arc plate, and the first arc plate and the second arc plate are spliced to form the mounting part. When the outer plate and the inner lining plate are stacked and spliced, the first arc plate and the second arc plate can be spliced to form the mounting part, wherein the mounting part with a relatively large arc does not need to be molded independently, and the arc is separately molded on the outer plate and the inner lining plate respectively, which can reduce the manufacturing difficulty of the mounting part, and meanwhile ensure a simple structure of the air deflector for processing and assembling. In an optional embodiment, the mounting part is of a hollow structure, so that the strength of the mounting part is not affected while the material is saved, and output required by the driving device can be reduced.
In an optional embodiment, a circle center of the first arc plate is coincident with a circle center of the second arc plate, and a radius of the first arc plate is equal to a radius of the second arc plate. By configuring the first arc plate and the second arc plate to have the same radius and have coincident centers, structural regularity of the mounting part formed by splicing the first arc plate and the second arc plate can be ensured, and smoothness of rotation of the air deflector is further ensured. In an optional embodiment, an arc length of the first arc plate is greater than an arc length of the second arc plate.
In an optional embodiment, the inner lining plate further includes an air guiding lining plate, wherein one end of the air guiding lining plate is connected to one end of the second arc plate not connected to the first arc plate, and the other end of the air guiding lining plate is connected to the outer plate, and wherein the air guiding lining plate includes a third arc plate and a fourth arc plate that are connected in sequence, wherein one end of the third arc plate away from the fourth arc plate is connected to one end of the second arc plate not connected to the first arc plate, one end of the fourth arc plate away from the third arc plate is connected to the outer plate, a side surface of the third arc plate facing away from the outer plate is a concave surface, and a side surface of the fourth arc plate facing away from the outer plate is a convex surface, so that an air guiding surface of the air guiding lining plate is substantially S-shaped. When the air conditioner heating, the hot air blown out from the air outlet can flow under the guidance of the air guiding lining plate, and being blocked by the air guiding surface of the air guiding lining plate, the hot air blown out from the air outlet will not directly float upwards to the upper space after leaving the air outlet, thus promoting the heating uniformity degree of the upper space and the lower space, further improving the heating effect of the air conditioner, and enhancing the user's using comfort. When the air conditioner is cooling, no matter for a vertical air conditioner or a hanging air conditioner, as the air outlet of the indoor unit is arranged at a relatively high place in the room, when the air deflector has a relatively large opening angle, under the guidance of the air guiding lining plate, cold air blown out from the air outlet will not directly flow downwards to the lower space after leaving the air outlet, thus promoting a cooling uniformity degree of the upper space and the lower space, further improving cooling effect of the air conditioner, and enhancing the user's using comfort.

When the air deflector is located at the first position, through the abutment of the fitting portion against the first wall surface of the limiting portion, the air deflector, when at the first position, is limited from colliding with the casing. When the air deflector is located at the second position, through the abutment of the fitting portion against the second wall surface of the limiting portion, the air deflector, when at the second position, is limited from collision and wear with the casing. By providing the limiting portion on the casing and providing the fitting portion on the air deflector, the limiting positions of the air deflector are limited through the fitting between the limiting portion and the fitting portion, thus avoiding collision and wear of the air deflector with the casing, and solving the problem of damage and abnormal noises of the air deflector.
Optionally, the fitting portion has a third wall surface and a fourth wall surface, wherein when the air deflector is at the first position, the third wall surface abuts against the first wall surface, and when the air deflector is at the second position, the fourth wall surface abuts against the second wall surface. When the air deflector is at the first position, through the abutment of the third wall surface of the fitting portion against the first wall surface of the limiting portion, the limiting effect of the air deflector when at the first position can be better improved.

Detailed Description of Embodiments

The present disclosure is further described in detail below with reference to drawings and embodiments. It can be understood that specific embodiments described herein are merely used to explain the present disclosure but not to limit the present disclosure. Besides, it further should be noted that in order to facilitate the description, only some but not all structures related to the present disclosure are shown in the drawings.
Referring to FIG. 1, an indoor unit 100 of an air conditioner of the present embodiment includes a casing 110 and an air deflector 150, the casing 110 is provided with an air outlet 117, the air outlet 117 is configured to blow air into room, an assembly groove 119 is recessed on an outer wall of the casing 110, and the assembly groove 119 is configured for the air deflector 150 to be embedded therein and is rotatably fitted with the air deflector 150, so as to realize installation of the air deflector 150. The air deflector 150 is mounted in the assembly groove 119 so as to be rotatably connected to the casing 110 in a provided rotation region. In the provided rotation region, the air deflector 150 can be driven by other driving devices to rotate back and forth, and also can stay at any position in the rotation region. A specific range is determined according to actual needs. Since the air deflector 150 is mounted in the assembly groove 119 on the outer wall of the casing 110, the whole air deflector 150 is within a visible range of users, thus a rotation process of the air deflector 150 is visualized. In practical applications, after the air deflector 150 is mounted in the assembly groove 119, the rotation process of the air deflector 150 can be easily observed, thus the rotation process is visualized, and it is convenient for the user to adjust the angle of the air deflector 150 quickly. It can be understood that, in practical applications, the air deflector 150 is provided with a driving device, so as to drive the air deflector 150 to rotate to a plurality of angles, and guide the air from the air outlet 117 in different directions.
Referring to FIG. 2, for a casing of the present embodiment, the assembly groove 119 is located above the outside of the air outlet 117, and is parallel to a length direction of the air outlet 117. After being mounted in the assembly groove 119, the air deflector 150 is driven by the driving device to rotate in a vertical plane. The assembly groove 119 is located above the air outlet 117, and after the air deflector 150 is mounted in the assembly groove 119, when the indoor unit 100 to which the casing 110 provided in the present embodiment is applied runs in a heating mode, the air deflector 150 should be in a position with a relatively small opening degree. Hot air blown out from the air outlet 117 will immediately float upwards after leaving the air outlet 117, and the air deflector 150 has a pressing effect on this part of hot air. Being blocked by the air deflector 150, the hot air blown out from the air outlet 117 will not directly float upwards to an upper space after leaving the air outlet 117, thus promoting a heating uniformity degree of the upper space and a lower space, further improving the heating effect of the air conditioner, and enhancing the user's using comfort. When the air conditioner is cooling, the air deflector 150 should be in a position with a relatively large opening degree, and no matter for a vertical air conditioner or a hanging air conditioner, as the air outlet 117 of the indoor unit 100 is arranged at a relatively high place in the room, when the air deflector 150 has a relatively large opening degree, under the guidance of the air deflector 150, cold air blown out from the air outlet 117 will not directly flow downwards to the lower space after leaving the air outlet 117, thus promoting a cooling uniformity degree of the upper space and the lower space, further improving cooling effect of the air conditioner, and enhancing the user's using comfort.
For the casing 110 provided in the present embodiment, as the assembly groove 119 for mounting the air deflector 150 is provided on the outer wall of the casing 110, model selection of the air deflector 150 is not limited by a dimension of the air outlet 117, as long as the air outlet 117 can be completely shielded in a power-off state. That is, the casing 110 provided in the present embodiment can be provided with the air deflector 150 of a larger dimension, and further the air guide effect is significantly improved.
Referring to FIG. 1 and FIG. 2, in the present embodiment, in order to improve a utilization rate of the air deflector 150 so as to save production costs, the assembly groove 119 is joined with an upper edge of the air outlet 117, which can be understood as that the assembly groove 119 is in communication with the air outlet 117. In cases where the air deflector 150 is rotatably fitted with the assembly groove 119, a part of the air deflector 150 close to the assembly groove 119 also can have a flow guiding effect on the air outlet 117, that is, the utilization rate of the air deflector 150 is improved. The longer a distance between the assembly groove 119 and the air outlet 117 is, the lower the utilization rate of air guiding effect of the air deflector 150 is. By joining the assembly groove 119 with the upper edge of the air outlet 117, the utilization rate of the air deflector 150 can be maximized, thus avoiding a too large dimension of the air deflector 150, and saving the production costs. The assembly groove 119 is parallel to an extending direction of the air outlet 117, and in an actual operation process, each part of the air deflector 150 connected to the assembly groove 119 can have the air guiding effect, thus further improving the utilization rate of the air deflector 150.
Moreover, considering that the air outlet 117 of most indoor units 100 on the market has a rectangular structure with long sides extending in the horizontal direction, in order to be adapted to most indoor units 100 on the market, in the present embodiment, the assembly groove 119 extends along the horizontal direction, that is, the upper edge of the air outlet 117 also extends along the horizontal direction. The assembly groove 119 extends along the horizontal direction, that is, the upper edge of the air outlet 117 also extends along the horizontal direction, improving aesthetic degree after the air deflector 150 is assembled.
Referring to FIG. 3 and FIG. 4, the air deflector 150 includes a mounting part 159 and an air guiding part 157, where the mounting part 159 is configured to be fitted and mounted with the assembly groove 119, and after the air deflector 150 is mounted to the assembly groove 119, in order to realize smooth rotation, and further ensure close fitting of the air deflector 150 to prevent generation of a too big gap, in the present embodiment, the assembly groove 119 is configured as a semi-cylindrical groove, i.e., a cross section of the assembly groove 119 is in a semi-arc shape. In practical applications, corresponding to the structure of the assembly groove 119, one side of the chosen air deflector 150 needs to be provided with the mounting part 159 in a cylindrical shape, wherein the mounting part 159 is embedded into the assembly groove 119, and through rotational fitting between the mounting part 159 and the assembly groove 119, rotational fitting between the air deflector 150 and the casing 110 is realized. Since the assembly groove 119 is recessed on the outer wall of the casing 110, a connection structure between the air deflector 150 and the casing 110 is prevented from protruding outwards, thus improving overall aesthetic degree of the casing 110. Meanwhile, the air deflector 150 is connected to the matched assembly groove 119 through an arc-shaped part, so that the gap between the mounting part 159 and the assembly groove 119 is as small as possible, thus preventing condensation on the outer wall of the casing 110.
In some embodiments, in order to further ensure the anti-condensation effect, lengths of the mounting part 159 and the air deflector 150 are both corresponding to the length of the assembly groove 119. That is, in the case where the mounting part 159 is embedded into the assembly groove 119, two ends of the mounting part 159 are coplanar with end walls of the two ends of the assembly groove 119, respectively, and two ends of the air deflector 150 in the length direction are coplanar with the end walls of the two ends of the assembly groove 119, respectively.
Further, the assembly groove 119 has one end opened on an end wall of one end of the casing 110 in the horizontal direction, and the other end extending to an end wall of the other end of the casing 110 in the horizontal direction. The two ends of the assembly groove 119 are respectively located on the end walls of the two ends of the casing 110 in the horizontal direction, i.e., the assembly groove 119 penetrates through the casing 110 in the horizontal direction, ensuring that after the air deflector 150 is mounted in the assembly groove 119, the air deflector 150 can be completely and tightly fitted with the outer wall of the casing 110 in the horizontal direction, thus avoiding generation of a too big gap in a blank area, and improving the anti-condensation effect.
In some embodiments, in order to facilitate transmission connection between the driving device and the air deflector 150 of the indoor unit 100, the drive device is avoided from being arranged outside, thus improving concealment and installation. A groove wall of the assembly groove 119 is opened with a groove hole 127, the driving device of the indoor unit 100 can be mounted inside the casing 110, and only an output end thereof extends into the assembly groove 119 through the groove hole 127 and is in transmission connection with a fitting roller of the air deflector 150, so as to drive the fitting roller, and realize the rotation of the air deflector 150 in the vertical plane.
Referring to FIG. 2, it should be noted that the indoor unit 100 includes the casing 110 and a panel, and the panel is provided on a surface of the casing 110. A recessed region 172 is recessed on the outer wall of the casing 110, the air outlet 117 is formed in the recessed region 172, and the recessed region 172 is configured to be fitted with the air deflector 150. Actually, the indoor unit 100 can receive the air deflector 150 in a power-off state, that is, the air deflector 150 shields the air outlet 117 when being embedded into the recessed region 172, so as to prevent the air deflector 150 from protruding from the surface of the casing 110 in the power-off state, and improve the aesthetic degree of the indoor unit 100, and moreover, dust accumulation at the air outlet 117 can be effectively prevented. The assembly groove 119 can be recessed on the outer wall of the casing 110, or can be recessed on an outer wall of the panel. In the present embodiment, for the sake of facilitating processing, the assembly groove 119 is recessed on the outer wall of the casing 110.
The casing 110 provided in the present embodiment, as the assembly groove 119 for mounting the air deflector 150 is recessed on the outer wall thereof, can be adapted to air deflectors 150 of more dimensions, without being limited by the dimension of the air outlet 117, and with mounting of the air deflectors 150 of a larger dimension, the air guiding effect can be significantly improved. Furthermore, as the assembly groove 119 is recessed on the outer wall of the casing 110, after fitting of the air deflector 150 and the assembly groove 119 is completed, the user can clearly observe the rotation process and the rotation angle of the air deflector 150, so that the air guide angle of the air deflector 150 can be adjusted in place more quickly. Furthermore, after the fitting of the air deflector 150 and the assembly groove 119 is completed, the air deflector 150 is embedded into the outer wall of the casing 110, and is tight fitted with the outer wall of the casing 110, and prevent generation of a too big gap, thus avoiding generation of condensation on the outer wall of the casing 110.
Therefore, the casing 110 provided in the present embodiment can be adapted to the air deflectors 150 of more dimensions, can realize the visualization of the rotation process and the rotation angle of the air deflector 150, further has the anti-condensation effect, and can significantly improve the user experience.
Referring to FIG. 5, an air deflector 150 of the present embodiment includes an outer plate 210 and an inner lining plate 220, wherein the inner lining plate 220 and the outer plate 210 are stacked and spliced, and there is a gap 230 between the outer plate 210 and the inner lining plate 220, wherein the inner lining plate 220 is configured to guide airflow blown out from the air outlet 117 of the air conditioner, and the outer plate 210 can be used to decorate and reinforce structural strength of the air deflector 150. When the air conditioner is heating, hot air blown out from the air outlet 117 can flow under the guidance of the inner lining plate 220, and the hot air blown out from the air outlet 117, under obstruction of the inner lining plate 220, will not directly float upwards to the upper space after leaving the air outlet 117, thereby improving the heating uniformity degree of the upper space and the lower space, further improving the heating effect of the air conditioner, and enhancing the user's using comfort.
Further, the outer plate 210 includes a first arc plate 211, the inner lining plate 220 includes a second arc plate 221, wherein the first arc plate 211 is connected to the second arc plate 221, and the first arc plate 211 and the second arc plate 221 are spliced to form the mounting part 159. When the outer plate 210 and the inner lining plate 220 are stacked and spliced, the first arc plate 211 and the second arc plate 221 can be spliced to form the mounting part 159, and the mounting part 159 with a relatively large arc does not need to be molded independently, wherein the arc is disassembled and separately molded on the outer plate 210 and the inner lining plate 220 respectively, which can reduce the manufacturing difficulty of the mounting part 159, and meanwhile ensure a simple structure of the air deflector 150 for processing and assembling. In an optional embodiment, the mounting part 159 is of a hollow structure, so that the strength of the mounting part 159 is not affected while the material is saved, and output required by the driving device can be reduced. Besides, the hollow structure facilitates transmission fitting of the air deflector 150 with the driving device through the hollow structure, and it is further convenient to drive the air deflector 150 by the driving device to rotate to different operation positions when the air deflector 150 is used in the air conditioner. For example, an inner side of the first arc plate 211 is provided with a clamping member, the driving device includes a driving shaft 171, wherein the driving shaft 171 can extend into the hollow mounting part 159 and is connected to the clamping member, and when the driving shaft 171 rotates, the first arc plate 211 can be driven by the driving shaft 171, further driving the whole air deflector 150 to rotate.
Referring to FIG. 6, in the present embodiment, the air deflector 150 further includes a mounting plate 231 and a pivot shaft 232 provided on the mounting plate 231, and the mounting plate 231 is fixedly connected to one end of the first arc plate 211 in the length direction; the casing 110 is provided with a pivot hole (not shown in the drawing), and the pivot shaft 232 is in pivot fitting with the pivot hole. Further, the driving device is in transmission fitting with one end of the air deflector 150 away from the pivot shaft 232; in this way, the air deflector 150 can be reliably provided on the casing 110, and the air deflector 150 can be driven by the driving device to reliably rotate, so as to adjust the air guiding direction.
Further, a circle center of the first arc plate 211 is coincident with a circle center of the second arc plate 221, and a radius of the first arc plate 211 is equal to a radius of the second arc plate 221. By configuring the first arc plate 211 and the second arc plate 221 to have the same radius and have coincident centers, structural regularity of the mounting part 159 formed by splicing the first arc plate 211 and the second arc plate 221 can be ensured, and smoothness of rotation of the air deflector 150 is further ensured. Further, an arc length of the first arc plate 211 is greater than an arc length of the second arc plate 221; in this way, the first arc plate 211 is allowed to have a larger surface area, which is beneficial for the driving device to achieve transmission connection with the air deflector 150 through the first arc plate 211. Certainly, in other embodiments, an arc length of the first arc plate 211 is equal to or smaller than an arc length of the second arc plate 221, which is not specifically limited herein.
In the present embodiment, the inner lining plate 220 further includes an air guiding lining plate 222, wherein one end of the air guiding lining plate 222 is connected to one end of the second arc plate 221 not connected to the first arc plate 211, and the other end of the air guiding lining plate 222 is connected to the outer plate 210; the air guiding lining plate 222 is configured to guide the airflow blown out from the air outlet 117 of the air conditioner and block the airflow from floating upwards. By guiding the airflow blown out from the air outlet 117 of the air conditioner and preventing the airflow from flowing upwards by the air guiding lining plate 222, when the air conditioner is heating, the hot air will not directly float upwards to the upper space after leaving the air outlet 117, thus promoting the heating uniformity degree of the upper space and the lower space, further improving the heating effect of the air conditioner, and enhancing the user's using comfort. When the air conditioner is cooling, no matter for a vertical air conditioner or a hanging air conditioner, as the air outlet 117 of the indoor unit 100 is arranged at a relatively high place in the room, when the air deflector 150 has a relatively large opening angle, under the guidance of the air guiding lining plate 222, cold air blown out from the air outlet 117 will not directly flow downwards to the lower space after leaving the air outlet 117, thus promoting a cooling uniformity degree of the upper space and the lower space, further improving cooling effect of the air conditioner, and enhancing the user's using comfort. The air guiding lining plate 222 can be shaped according to needs, and the air guiding lining plate 222 in the present embodiment is an arc-shaped plate, so as to better guide flow of the airflow blown out from the air outlet 117 with the streamlined air guiding lining plate 222.

In this way, not only the flow of the airflow blown out from the air outlet 117 can be guided, but also the hot air blown out from the air outlet 117 can be reliably blocked by the air guiding lining plate 222 from directly floating upwards after leaving the air outlet 117; certainly, in other embodiments, the substantially S-shaped air guiding lining plate 222 can also reliably block the cold air blown out from the air outlet 117 from directly moving downwards after leaving the air outlet 117. It should be understood that, in other embodiments, the air guiding lining plate 222 only includes the third arc plate 223, and the concave surface of the third arc plate 223 faces away from the outer plate 210.

Referring to FIG. 9 and FIG. 10, in the present embodiment, the air deflector 150 has a first position and a second position, wherein the first position and the second position are two limiting positions of rotation of the air deflector in the rotation region configured for the assembly groove. The casing 110 is provided with a limiting portion 111, and the limiting portion 111 includes a first wall surface 113 and a second wall surface 115. The air deflector 150 is provided with a fitting portion 151. When the air deflector 150 is at the first position, the fitting portion 151 abuts against the first wall surface 113. When the air deflector 150 is at the second position, the fitting portion 151 abuts against the second wall surface 115.
In the present embodiment, by providing the limiting portion 111 on the casing 110 and providing the fitting portion 151 on the air deflector 150, the air deflector 150 is limited through the fitting between the limiting portion 111 and the fitting portion 151, thus avoiding collision and wear of the air deflector 150 with the casing 110, and solving the problem of damage and abnormal noises of the air deflector 150. When the air deflector 150 is located at the first position, through the abutment of the fitting portion 151 against the first wall surface 113 of the limiting portion 111, the air deflector 150 is avoided from collision and wear with the casing 110 when the air deflector 150 is at the first position. When the air deflector 150 is located at the second position, through the abutment of the fitting portion 151 against the second wall surface 115 of the limiting portion 111, the air deflector 150 is avoided from collision and wear with the casing 110 when the air deflector 150 is at the second position, and solving the problem caused by collision, wear, and abnormal noises of the air deflector 150 with the casing 110.

By providing the through groove 121 on the limiting portion 111, it is easy for the mounting part 159 to pass through, and the mounting part 159 can be pre-positioned through the through groove 121. By making the fitting portion 151 protruded from the side wall of the mounting part 159, the fitting between the fitting portion 151 and the limiting portion 111 is facilitated.
In the present embodiment, the fitting portion 151 is protruded from the side wall of the mounting part 159. The third wall surface 153 and the fourth wall surface 155 are two opposite side walls of the fitting portion 151, and the third wall surface 153 and the fourth wall surface 155 are respectively connected to the side wall of the mounting part 159. The first wall surface 113 and the second wall surface 115 are located at two sides of the through groove 121. Thus, it is more convenient to provide the first wall surface 113 and the second wall surface 115, and it also can avoid interference when mounting the air deflector 150.
In some other embodiments of the present disclosure, the fitting portion 151 also can be protruded from the end portion of the mounting part 159 and fitted with the protruded limiting portion 111, so as to limit the first position and the second position of the air deflector 150. Alternatively, the fitting portion 151 is protruded from the side wall of the mounting part 159 and fitted with the limiting portion 111 protruded from the bottom wall of the assembly groove 119, so as to limit the first position and the second position of the air deflector 150.
Referring to FIG. 13 and FIG. 14, in the present embodiment, the mounting part 159 includes a first segment 163 and a second segment 165 connected with each other. The first segment 163 is protruded from the end portion of the mounting part 159. The fitting portion 151 is protruded from a side wall of the second segment 165. The through groove 121 includes a first groove segment 123 and a second groove segment 125. The first wall surface 113 and the second wall surface 115 are located at two sides of the second groove segment 125 respectively, and both the first wall surface 113 and the second wall surface 115 are both connected to a side wall of the second groove segment 125. The first segment 163 is mounted in the first groove segment 123, and the second segment 165 is mounted in the second groove segment 125. Through providing the fitting between the first segment 163 and the first groove segment 123, the position of the air deflector 150 can be pre-positioned when mounting the air deflector 150, so that an axis of the mounting part 159 is substantially coincident with an axis of the assembly groove 119, ensuring that the mounting part 159 better rotates in the assembly groove 119. Meanwhile, mounting accuracy of the fitting portion 151 also can be ensured, so that position limiting accuracy of the air deflector 150 is higher.
In the present embodiment, a diameter of the first segment 163 is greater than a diameter of the second segment 165. A diameter of the first groove segment 123 is greater than a diameter of the second groove segment 125. By making the diameter of the first segment 163 greater than the diameter of the second end, the mounting part 159 forms a stepped shaft. By making the diameter of the second groove segment 125 is greater than the diameter of the first groove segment 123, the through groove 121 forms a stepped groove, such that left and right positions of the air deflector 150 are pre-defined through fitting between the step of the mounting part 159 and the step of the through groove 121, thus facilitating the mounting of the air deflector 150.
In the present embodiment, the first segment 163 is clearance-assembled in the first groove segment 123. That is, the diameter of the first segment is slightly smaller than the diameter of the first groove segment 123, and the length of the first segment 163 is slightly smaller than the length of the first groove segment 123. Through the clearance-assembling of the first segment 163 with the first groove segment 123, the first segment 163 will not generate friction with a side wall of the first groove segment 123 during rotation, thus avoiding wear of the first segment 163 or the first groove segment 123. The second segment 165 is clearance-assembled in the second groove segment 125. That is, a diameter of the second segment 165 is slightly smaller than a diameter of the second segment 125. Through the clearance-assembling of the second segment 165 with the second groove segment 125, the second segment 165 will not generate friction with a side wall of the second groove segment 125 during rotation, thus avoiding wear of the second segment 165 or the second groove segment 125.
Referring to FIG. 8, FIG. 15, and FIG. 16, in the present embodiment, the indoor unit 100 further includes a driving box 170. The casing 110 is formed with a groove hole 127. The groove hole 127 is located at one side of the limiting portion 111 close to an end portion of the casing 110. The driving box 170 is mounted on the casing 110, and the driving box 170 extends out of the groove hole 127 to be connected with the second end, so as to drive the air deflector 150 to rotate. By making the driving box 170 extend out of the casing 110 to be connected with the air deflector 150, the air deflector 150 can be better assembled on the casing 110.
In the present embodiment, a polygonal connecting hole 167 is recessed at an end portion of the second segment 165, and the driving box 170 has a polygonal driving shaft 171, wherein the driving shaft 171 extends into the connecting hole 167 to drive the air deflector 150 to rotate.
