Thus, the sliding member <NUM> drives the outer air deflector <NUM> to rotate, and manufacturing process is simple.

As shown in <FIG>, a positioning portion <NUM> is disposed at a side of the sliding member <NUM> proximate to the outer air deflector <NUM>, that is, the positioning portion <NUM> is disposed at a side of the sliding member <NUM> facing an exterior of the air conditioner indoor unit <NUM>. An extension axis of the positioning portion <NUM> is parallel to the sliding member <NUM>, and the positioning groove <NUM> is defined by the positioning portion <NUM> and the sliding member <NUM>. In this way, fixing reliability of the sliding member <NUM> is effectively ensured, materials are saved, and costs are reduced.

Further, two limiting strips <NUM> are disposed at the side of the sliding member <NUM> proximate to the outer air deflector <NUM>. The two limiting strips <NUM> are perpendicular to the extension axis of the positioning portion <NUM>, and are disposed at both ends of the positioning groove <NUM> to limit positions of the positioning protrusions <NUM> in the positioning groove <NUM>.

That is to say, the two extension pieces <NUM> extend toward the exterior of the air conditioner indoor unit <NUM>, and a distance between the two extension pieces <NUM> is smaller than a diameter of the extension column <NUM>. As a result, it is possible to prevent the extension column <NUM> from falling off, and to ensure fixing reliability of the extension column <NUM>. The positioning groove <NUM> is defined by the extension pieces <NUM> and the sliding member <NUM>.

Referring to <FIG> and <FIG>, when the outer air deflector <NUM> and the outer driving device <NUM> are mounted, the sliding member <NUM> moves toward a center of the outer air deflector <NUM>. After the sliding rod <NUM> is aligned with a hole in a side plate of the outer air deflector <NUM>, the sliding member <NUM> is pushed toward the rotating arm <NUM>, so that the rotating arm <NUM> is hinged with the outer air deflector <NUM>. During disassembly, the sliding member <NUM> may be pushed in a direction away from the rotating arm <NUM> with force. Specifically, as shown in <FIG>, a back surface of the sliding member <NUM> is provided with the positioning portion <NUM>, and the positioning groove <NUM> is defined by the positioning portion <NUM> and a side surface of the sliding member <NUM>. Left and right ends of the positioning groove <NUM> are provided with the limiting strips <NUM>, and an upper edge and a lower edge of the sliding portion <NUM> on a rear side plate of the outer air deflector <NUM> are provided with the positioning protrusions <NUM>. During mounting, the positioning protrusions <NUM> are located in the positioning groove <NUM>, and the connection between the rotating arm <NUM> and the outer air deflector <NUM> is achieved through left and right sliding of the sliding member <NUM> on the sliding portion <NUM>.

In some optional embodiments, the sliding rod <NUM> and the extension column <NUM> are metal pieces, the sliding member <NUM> and the extension pieces <NUM> are plastic pieces, and the sliding rod <NUM>, the extension column <NUM>, the sliding member <NUM> and the extension pieces <NUM> are integrally formed by means of injection molding. Therefore, strength of the sliding rod <NUM> and the extension column <NUM> is ensured, assembly is easy, and manufacturing process is simple.

As shown in <FIG> and <FIG>, according to some embodiments of the present invention, a left recessed portion <NUM> and a right recessed portion <NUM> are respectively disposed at a front side of the left side cover <NUM> and a front side of the right side cover <NUM>. After the left side cover <NUM> and the right side cover <NUM> are assembled to the outer cover <NUM>, the left recessed portion <NUM>, the right recessed portion <NUM> and the outer cover <NUM> jointly define the second accommodating portion <NUM>. An outer plate mounting column <NUM> is further disposed at each of the front side of the left side cover <NUM> and the front side of the right side cover <NUM>, and a lower end of the outer air deflector <NUM> is pivotally connected to the outer plate mounting column <NUM>. Referring to <FIG>, the left side cover <NUM> and the right side cover <NUM> are respectively fixed to a left end and a right end of the outer cover <NUM>, and an outer plate mounting column <NUM> is further disposed at each of the front side of the left side cover <NUM> and the front side of the right side cover <NUM>. The lower end of the outer air deflector is pivotally connected to the outer plate mounting column <NUM>. The lower end of the outer air deflector <NUM> is pivotally connected to the outer plate mounting column <NUM>, and the outer air deflector <NUM> is pivotally fixed in the second accommodating space, so that the mounting space of the outer air deflector <NUM> is ensured, and the outer air deflector <NUM> is easy to be installed.

According to some specific embodiments of the present invention, as shown in <FIG>, <FIG> and <FIG>, the outer air deflector <NUM> is hollow inside, and includes an outer plate rear panel <NUM> and an outer plate front panel <NUM> connected to each other. The outer plate rear panel <NUM> has an arc-shaped plate protruding toward the outer plate front panel <NUM>. As a result, an airflow Coanda effect is formed, and an air supply distance of the air conditioner indoor unit <NUM> is increased. Moreover, it is possible to facilitate that air from the air outlet <NUM> is blown upward and then falls freely to form shower-style blowing when the outer air deflector <NUM> is opened, and in turn, to improve comfort of the user.

In some optional embodiments, as shown in <FIG>, the outer plate rear panel <NUM> is provided with a plurality of parallel outer plate patterns <NUM> extending in a left-right direction, so that strength of the outer air deflector <NUM> is ensured, a weight of the outer air deflector <NUM> is reduced, and a light weight of the outer air deflector <NUM> is achieved.

According to the air conditioner indoor unit <NUM> in the embodiments of the present invention, as shown in <FIG>, after the air conditioner indoor unit <NUM> is mounted, a distance L2 between an upper end of a mounting portion of the outer air deflector <NUM> and a wall is larger than a distance L1 between a lower end of the mounting portion of the outer air deflector <NUM> and the wall. In this way, it is possible to blow the air from the air outlet <NUM> in a direction away from the wall when the air conditioner indoor unit <NUM> is in operation, to reduce a gap through which air flows between the mounting portion of the outer air deflector <NUM> and the outer air deflector <NUM>, and in turn, to reduce condensation on the front surface of the outer air deflector <NUM>.

In some further embodiments of the present invention, referring to <FIG> and <FIG>, the inner air deflector <NUM> is hollow inside, and includes an inner plate rear panel <NUM> and an inner plate front panel <NUM> connected to each other. The inner plate front panel <NUM> is configured as an arc-shaped panel protruding backward. In addition, radians of the inner plate rear panel <NUM> and the inner plate front panel <NUM> are different, and the radian of the inner plate rear panel <NUM> is larger than the radian of the inner plate front panel <NUM>, so that strength of the inner air deflector <NUM> is effectively ensured.

In some optional embodiments, as shown in <FIG> and <FIG>, an upper end of the inner air deflector <NUM> is configured as an arc-shaped end, which effectively ensures that the inner air deflector <NUM> is pivotally fixed in the first accommodating portion <NUM>. An extension length of the inner plate rear panel <NUM> is smaller than an extension length of the inner plate front panel <NUM>, and a lower end of the inner plate front panel <NUM> is bent backward, and covers a lower end of the inner plate rear panel <NUM>. A bending angle of the lower end of the inner plate front panel <NUM> is in a range of <NUM> degrees to <NUM> degrees inclusive, which is optionally approximately <NUM> degrees, but is not limited thereto. Therefore, it is possible to facilitate integral formation of the inner plate rear panel <NUM> and the inner plate front panel <NUM>, and manufacturing process is simple.

In some optional embodiments, at least one of the inner plate rear panel <NUM> and the inner plate front panel <NUM> is provided with a plurality of parallel inner plate patterns <NUM> extending in the left-right direction. In examples shown in <FIG> and <FIG>, a rear surface of the inner plate rear panel <NUM> is provided with inner plate patterns <NUM>, and a front surface of the inner plate front panel <NUM> is provided with inner plate patterns <NUM>. In this way, it is possible to facilitate to achieve a guide effect on airflow, to reduce a weight of the inner air deflector <NUM>, and to achieve a light weight of the part. Of course, it may also be possible to provide the inner plate patterns <NUM> on only the inner plate rear panel <NUM> or the inner plate front panel <NUM>.

According to the present invention, when the inner air deflector <NUM> is at a first closed position, a thickness of the upper end of the inner air deflector <NUM> is larger than a thickness of a lower end thereof. Referring to <FIG> and <FIG>, when the inner air deflector <NUM> is closed, the thickness of the upper end of the inner air deflector <NUM> is larger than the thickness of the lower end thereof, so that it is possible to effectively ensure the strength of the inner air deflector <NUM>, and to avoid breakage of the inner air deflector <NUM> during rotation. Herein, it will be noted that, when the inner air deflector <NUM> is closed, an end of the inner air deflector <NUM> facing an exterior of the air conditioner indoor unit <NUM> and at a high position is referred to as "an upper end" (i.e., a pivoting end), and an end of the inner air deflector <NUM> facing the interior of the air conditioner indoor unit <NUM> and at a low position is referred to as "a lower end" (i.e., a free end).

As shown in <FIG>, the first accommodating portion <NUM> includes a first arc panel <NUM>, a first left side plate <NUM> and a first right side plate <NUM>. The first arc panel <NUM> is located at a side of the housing <NUM>, and protrudes backward. In this way, it is possible to ensure that the arc shape of the first arc panel <NUM> is same as that of the inner air deflector <NUM>, to improve a degree of engagement between the inner air deflector <NUM> and the first arc panel <NUM> when the inner air deflector <NUM> is closed, and to reduce a gap between the inner air deflector <NUM> and the outer cover <NUM>. The first left side plate <NUM> and the first right side plate <NUM> are respectively located at a left side and a right side of the first arc panel <NUM>. The first left side plate <NUM>, the first right side plate <NUM>, and the first arc panel <NUM> define the first accommodating space, and the inner air deflector <NUM> is pivotally located in the first accommodating space.

An end of each of the first inner plate mounting column <NUM> and the second inner plate mounting column <NUM> is inserted and fixed into the inner plate mounting hole, and the other end thereof is exposed and is pivotally connected to the inner air deflector <NUM>, so that fixing reliability of the inner air deflector <NUM> is effectively ensured.

According to some embodiments of the present invention, as shown in <FIG>, the housing <NUM> further includes an inner plate mounting plate <NUM>. The inner plate mounting plate <NUM> is disposed on the outer cover <NUM>, and a rear end of the inner plate mounting plate <NUM> is connected to a top of the first arc panel <NUM>. The inner air deflector <NUM> is mounted on the inner plate mounting plate <NUM>, a rear end of the inner plate mounting plate <NUM> extends rearward to form fasteners, a top portion of the outer cover <NUM> has clamping grooves, and the fasteners cooperate with the clamping grooves to mount the inner plate mounting plate <NUM> on the top portion of the outer cover <NUM>.

Therefore, the inner plate mounting plate <NUM> and the outer cover <NUM> may be separately formed by means of injection molding, and the inner plate mounting plate <NUM> and the outer cover <NUM> may be easily demolded, manufactured and assembled.

In some further embodiments of the present invention, the outer plate mounting column <NUM> has a fixing hole. At least one end of the outer air deflector <NUM> has a movable latch assembly <NUM>. That is to say, one end of the outer air deflector <NUM> may be provided with a movable latch assembly <NUM>, or both ends of the outer air deflector <NUM> are each provided with a movable latch assembly <NUM>. The movable latch assembly <NUM> is matched with the fixing hole and locked with the corresponding left side cover <NUM> and/or right side cover <NUM>. As shown in <FIG>, a right end of the outer air deflector <NUM> is provided with the movable latch assembly <NUM>, and when the outer air deflector <NUM> is mounted, the movable latch assembly <NUM> is used in cooperation with the outer plate mounting column <NUM> of the right side cover <NUM>, so that it is possible to effectively ensure the fixing reliability of the outer air deflector <NUM> and to facilitate the mounting and removal of the outer air deflector <NUM>.

In some further embodiments of the present invention, as shown in <FIG>, the left and right ends of the outer air deflector <NUM> each vertically extend to form a side wall <NUM>. As shown in <FIG>, a side wall <NUM> at a corresponding side has a first fixing hole <NUM> and a second fixing hole <NUM>, a baffle plate <NUM> is further disposed at a side of the outer air deflector <NUM> adjacent to the side wall <NUM>, and the baffle plate <NUM> has a third fixing hole <NUM>. Specifically, referring to <FIG>, a right side wall <NUM> of the outer air deflector <NUM> is provided with a first fixing hole <NUM> and a second fixing hole <NUM>, a baffle plate <NUM> is located at a left side of the right side wall <NUM> of the outer air deflector <NUM>, and a third fixing hole <NUM> is disposed at a side of the baffle plate <NUM> away from the outer air deflector <NUM>. As shown in <FIG>, the movable latch assembly <NUM> is located between the side wall <NUM> and the baffle plate <NUM>, and includes a first fixing column <NUM>, a second fixing column <NUM>, a latch column <NUM> and a spring <NUM>. The first fixing column <NUM> is inserted into the first fixing hole <NUM>, and the second fixing column <NUM> is parallel to the first fixing column <NUM>, and is connected to the first fixing column <NUM> through a connecting column. The second fixing column <NUM> passes through the second fixing hole <NUM> and cooperates with the fixing hole of the outer plate mounting column <NUM>. The latch column <NUM> is disposed at an upper portion of the connecting column and extends away from the first fixing column <NUM>, and the latch column <NUM> passes through the third fixing hole <NUM>. The spring <NUM> is sleeved on the latch column <NUM>. Therefore, it is possible to effectively ensure fixing reliability of the movable latch assembly <NUM>, to limit the spring <NUM> of the movable latch assembly <NUM> by means of the third fixing hole <NUM> in the baffle plate <NUM>, and to ensure that the movable latch assembly <NUM> extends and retracts due to force of the spring <NUM>.

During the mounting, the movable latch assembly <NUM> is mounted between the right side wall <NUM> of the outer air deflector <NUM> and the baffle plate <NUM>, and both ends of the spring <NUM> are in contact with the side wall <NUM> and the baffle plate <NUM>. In this case, a free end of the latch column <NUM> passes through the third fixing hole <NUM>, and the first fixing column <NUM> and the second fixing column <NUM> are respectively pushed into the first fixing hole <NUM> and the second fixing hole <NUM> due to action of the spring <NUM>. The second fixing column <NUM> is matched with the fixing hole of the outer plate mounting column <NUM>.

In some optional embodiments, the movable latch assembly <NUM> is disposed at a side of the outer air deflector <NUM>, and a third fixing column <NUM> is disposed at the other side of the outer air deflector <NUM>, and the third fixing column <NUM> cooperates with a fixing hole at a corresponding side.

When the outer air deflector <NUM> is mounted, the third fixing column <NUM> at the left side of the outer air deflector <NUM> is aligned with the fixing hole in the outer plate mounting column <NUM> of the left side cover <NUM>, and the third fixing column <NUM> is inserted into the fixing hole. Afterward, the movable latch assembly <NUM> at the right side of the outer air deflector <NUM> is fixed. By pressing the first fixing column <NUM>, the spring <NUM> is compressed, and the second fixing column <NUM> and the latch column <NUM> move toward the left side of the outer air deflector <NUM>. In this case, the second fixing column <NUM> is hidden in the second fixing hole <NUM> of the side wall <NUM> of the outer air deflector. The outer air deflector <NUM> is aligned with the outer plate mounting column <NUM> of the right side cover <NUM>, and the first fixing column <NUM> is released. Due to action of the force of the spring, the second fixing column <NUM> and the latch column <NUM> move toward the right side of the outer air deflector <NUM>. The second fixing column <NUM> is exposed from the second fixing hole <NUM>, and is inserted into the outer plate mounting column <NUM>, thereby completing the mounting of the outer air deflector <NUM>.

According to the air conditioner indoor unit <NUM> in the embodiments of the present invention, as shown in <FIG>, when the air conditioner indoor unit <NUM> is in a cooling mode, the inner air deflector <NUM> swings to an uppermost position, and the outer air deflector <NUM> swings to supply air. As shown in <FIG>, when the air conditioner indoor unit <NUM> is in a heating mode, the outer air deflector <NUM> swings to the lowermost position, and the inner air deflector <NUM> swings to supply air. In this way, regardless of whether the air conditioner indoor unit <NUM> is in the cooling mode or in the heating mode, the user can experience the shower-style blowing, and in turn, the comfort of the user is improved.
