Those of ordinary skill in the art will understand the specific meaning of the terms described above in the present utility model as the case may be.

In one aspect, the present utility model provides an air deflector for an air conditioner indoor unit. The indoor unit of the air conditioner is an indoor part of a split air conditioner or an indoor end machine type of a central air conditioner. The air conditioner is used for conditioning indoor air, including adjusting temperature, humidity, air quality of the air, humidifying the indoor air, dehumidifying, introducing fresh air, and the like. The air conditioner may be constituted by an evaporator, a condenser, a compressor, a throttle device and other necessary elements to form a vapor compression refrigeration cycle system to output cool/hot air through a fan to achieve cooling and heating of an indoor environment. The embodiment of the utility model does not limit the specific form of the air conditioner, and the air conditioner can be various household air conditioners, commercial central air conditioners and the like. Specifically, the specific form of the indoor unit of the air conditioner can be various forms such as wall hanging type, vertical type, integral type, patio type and the like.

The air deflector 50 of the embodiment of the present utility model is used to be installed on the housing 10 of the indoor unit of an air conditioner. In some embodiments, the air deflector 50 is installed at the air outlet 12 of the housing 10, and its function may include guiding the air outlet direction of the air outlet 12, and also may include closing the air outlet 12.

As shown in fig. 1 to 4, the air deflection 50 of the embodiment of the present utility model may generally include a plate body 51, a mounting arm 53, and a mounting bar 55.

The plate body 51 is plate-shaped, and may be a flat plate, a curved plate, for example, a curved plate, or the like. The plate 51 is used for guiding air. For example, the air may be guided by the plate 51 at the air outlet 12 (refer to fig. 6 and 7). In addition, the plate 51 may also be used to close the air outlet 12. The plate 51 is provided with a stopper pin 515.

The mounting arm 53 is for mounting to the housing 10. Specifically, for a wall-mounted air conditioning indoor unit, in an alternative embodiment, the housing 10 may include a skeleton, a shell, and a panel (not shown). The framework is arranged at the rear side of the housing, and the panel is arranged at the outer side of the housing and used for forming the appearance of the wall-mounted air conditioner indoor unit. The mounting arm 53 is preferably mounted to the housing. Of course, the mounting arm 53 may be mounted to a panel or a frame. The mounting bar 55 is configured to be reciprocally mounted to the plate 51 (reciprocally movable in the x-axis positive and negative directions) between a connected position (fig. 2) in which it is connected to the mounting arm 53 and a disconnected position (fig. 3) in which it is spaced apart from the mounting arm 53. In the connection position, the mounting bar 55 is connected to the mounting arm 53 to effect an indirect connection of the plate 51 to the mounting arm 53. In the disengaged position, the mounting bar 55 is spaced away from the mounting arm 53, i.e., the mounting bar 55 is decoupled from the mounting arm 53, thereby allowing the user to remove the plate 51.

The mounting bar 55 has a positioning portion 550. When the mounting lever 55 is in the coupling position and the uncoupling position, the positioning portions 550 are located on both sides of the stopper pin 515, respectively, so that the stopper pin 515 stops the positioning portions 550, thereby stably holding the mounting lever 55 in the coupling position and the uncoupling position, as shown in fig. 2 and 3.

Specifically, as shown in fig. 2, the mounting lever 55 is in the connection position, the positioning portion 550 is on the first side (left side as viewed from the drawing) of the stopper pin 515, and the positioning portion 550 cannot move toward the disconnection position (i.e., cannot move forward in x) due to the stopper pin 515, so that it can be stably held in the connection position. As shown in fig. 3, the mounting bar 55 is in the disengaged position, the positioning portion 550 is located on the second side (right side as viewed from the drawing) of the stopper pin 515, and the positioning portion 550 cannot move toward the connected position (i.e., cannot move negatively toward the x-axis) due to the stopper pin 515, so that the mounting bar 55 of the board 51 can be stably maintained in the disengaged position, thereby facilitating the user to reinstall the mounting bar 55 on the mounting arm 53.

In the embodiment of the present utility model, when the air deflector 50 is in a normal installation state, the installation rod 55 is in a connection position, and is connected to the installation arm 53 (the connection may be a fixed connection or a rotatable connection according to a specific structure). When the air deflector 50 needs to be detached, the mounting lever 55 is moved from the connection position to the disconnection position so that the mounting lever 55 is away from the mounting arm 53 to release the connection relationship with the mounting arm 53, and the user can remove the plate body 51 for cleaning operation. According to the embodiment of the utility model, the detachable connection of the plate body 51 and the mounting arm 53 is realized by moving the mounting rod, the mounting and the dismounting are very simple, and the plate body 51 can be dismounted for separate cleaning during the cleaning of the air conditioner.

In some embodiments, as shown in fig. 2-4, mounting bar 55 may be fixedly inserted into mounting arm 53. The mounting lever 55 has a hole 533 at one end, and the mounting lever 55 is inserted into the hole 533 at its end when in the connected position. The receptacle 533 is a non-circular hole to prevent rotation of the mounting rod 55 within the receptacle 533. The other end of the mounting arm 53 has a mounting hole 535, and the mounting hole 535 is used to be connected to a rotating shaft of a motor, so that the motor drives the mounting arm 53 and the plate 51 to rotate around a central axis of the mounting hole 535 to rotatably adjust a wind guiding angle of the plate 51 or adjust an open/close state of the plate 51.

In embodiments not illustrated in other figures, the mounting rod 55 may be rotatably inserted into the mounting arm 53, so that the mounting arm 53 is fixedly connected to the housing 10, and the mounting rod 55 and the plate 51 may rotate around a central axis of the mounting rod 55 to adjust the air guiding angle of the plate 51 or adjust the open/close state of the plate 51.

In some embodiments, as shown in fig. 1, the number of the mounting arms 53 may be one, and in addition, at least one fixing arm 58 is fixed to the plate 51, one end of the fixing arm 58 is fixed to the plate 51, and the other end is provided with an opening 581, where the opening 581 is used to be matched with a plug shaft (not shown) on the housing 10. In this way, when the plate body 51 is detached, the mounting lever 55 is first separated from the mounting arm 53, and then the plate body 51 is moved in the axial direction of the insertion shaft, so that the fixing arm 58 is separated from the insertion shaft, and the plate body 51 and the fixing arm 58 are completely detached from the housing 10.

In some embodiments, as shown in fig. 2 to 4, the limiting pin 515 may be telescopically mounted on the plate 51 along an axial direction thereof, and configured to retract toward the inside of the plate 51 when pressed by an external force, and to extend toward the outside of the plate 51 by virtue of an elastic force after the external force is removed. For example, as shown in fig. 5, a pin hole 518 may be formed in the plate body 51, and the pin hole 518 is a blind hole. The stopper pin 515 is telescopically inserted into the pin hole 518 with a spring 516 provided between the insertion end thereof and the blind end of the pin hole 518. Thus, when the stopper pin 515 is not pressed, it protrudes out of the pin hole 518 for blocking the positioning portion 550. When pressed inward, the stopper pin 515 is retracted into the pin hole 518 and the spring 516 is compressed. After the pressing force is removed, the stopper pin 515 is extended outward by the urging force of the spring 516 toward the outside. Thus, when the mounting lever 55 is switched between the connection position and the disconnection position (including movement from the connection position to the disconnection position and movement from the disconnection position to the connection position), the positioning portion 550 presses the stopper pin 515 to retract against the elastic force, thereby allowing the positioning portion 550 to move from one side to the other side of the stopper pin 515 beyond the head portion of the stopper pin 515, and then the stopper pin 515 is projected outward by the urging force of the spring 516 toward the outside to form a stopper for the positioning portion 550.

In this embodiment, since the limiting pin 515 is elastically telescopic, when the user switches the position of the mounting rod 55, the user only needs to apply a larger pushing force to force the limiting pin 515 to retract, thereby overcoming the stop of the limiting pin 515, completing the position switching process, and avoiding the need for the user to directly operate the limiting pin 515, so that the user operation is simpler.

In some embodiments, as shown in fig. 5, the outer surface 5152 of the head of the spacing pin 515 may be made partially spherical (i.e., a portion of a full sphere, such as a hemisphere). As shown in fig. 2 to 4, both side surfaces of the positioning portion 550 are inclined surfaces 551, 552 which clamp an acute angle with the axial direction of the stopper pin 515, so that the stopper pin 515 is pressed by the inclined surfaces 551, 552 to be urged to retract when the mounting lever 55 is reciprocated. For example, in the connected state shown in fig. 2, the mounting bar 55 is pushed positively in the x-axis, the ramp surface 552 of the positioning portion 550 will apply a force to the spacing pin 515 toward the positive x-axis and toward the negative y-axis, the component of which force toward the negative y-axis will push the spacing pin 515 into retraction, and then the positioning portion 550 passes over the head of the spacing pin 515, and then reaches the disengaged state shown in fig. 3. The state from the detached state of fig. 3 to the connected state of fig. 2 is opposite to the above-described state, and will not be described again here.

In some embodiments, as shown in fig. 2 to 4, a first mounting plate 511 and a second mounting plate 512 are formed on the plate body 51 at intervals, and a first mounting hole 5111 and a second mounting hole 5122 are formed in the two plates, respectively. The mounting rod 55 is interposed between the first mounting plate 511 and the second mounting plate 512, and axially both ends are axially movably inserted into the first mounting hole 5111 and the second mounting hole 5122, respectively. The first mounting plate 511 may be made substantially perpendicular to the plate body 51 and the second mounting plate 512 may be made substantially perpendicular to the plate body 51. The first mounting plate 511, the second mounting plate 512, and the plate body 51 are preferably integrally formed as a single piece, as shown in fig. 4. Of course, the first mounting plate 511 and the second mounting plate 512 may be detachably mounted to the plate body 51 by means of a snap-fit or the like. Alternatively, the first mounting plate 511 and the second mounting plate 512 may be connected by a connecting plate, and the first mounting plate 511, the second mounting plate 512 and the connecting plate may be integrally formed as a single piece, and the connecting plate may be attached to the plate 51 in parallel and detachably connected to the plate 51.

The mounting arm 53 is located on a side of the first mounting plate 511 remote from the second mounting plate 512, as shown in fig. 2, and the mounting lever 55 has an axial end extending out of the first mounting hole 5111 to connect the mounting arm 53 when in the connected position.

In some embodiments, as shown in fig. 4, the mounting arm 53 is provided with a polygonal receptacle 533. As shown in fig. 4, the receptacle 533 is "male" shaped. When the mounting rod 55 is connected, one end thereof is inserted into the insertion hole 533, and at least the outer contour of the insertion section thereof is matched with the shape of the insertion hole 533, and is also a polygonal shape of the same shape, so as to prevent the mounting rod 55 from rotating relative to the insertion hole 533.

Further, the outer contour of the axial both end sections of the mounting lever 55 may be made polygonal, and the first and second mounting holes 5111 and 5122 may be shaped polygonal to match the outer contour of the axial both end sections of the mounting lever 55, as shown in fig. 4, to prevent the mounting lever 55 from rotating relative to the first and second mounting holes 5111 and 5122.

In some embodiments, as shown in fig. 2-4, a handle 556 may be formed on the mounting bar 55 to facilitate the manual handling of the handle 556 to move the mounting bar 55. The handle 556 may be radially extended from the middle of the shaft body of the mounting shaft 55.

Further, when the mounting bar 55 is in the disengaged position, the handle 556 abuts against the inside of the second mounting plate 512, as shown in fig. 3. In this way, the handle 556 is stopped by the second mounting plate 512, allowing the mounting bar 55 to stop in the disengaged position.

In another aspect, the utility model provides an air conditioner indoor unit. The air conditioning indoor unit includes a housing 10 and at least one air deflection 50 as described in any of the embodiments above. The air outlet 12 is formed in the shell 10, the air deflector 50 is arranged at the air outlet 12, and the mounting arm 53 is mounted on the shell 10.

The specific form of the indoor unit of the air conditioner can be various forms such as wall hanging type, vertical type, integral type, courtyard type and the like. Fig. 6 and 7 illustrate an embodiment in which the air conditioning indoor unit is a wall-mounted air conditioning indoor unit.

For the wall-mounted air conditioner indoor unit, the air outlet 12 and the air deflector 50 can be made to be long in the horizontal transverse direction (the x direction marked in the figure), and the mounting arm 53 can be rotatably mounted on the casing 10, so that the air deflector 50 can rotatably open and close the air outlet 12 around the horizontal transverse axis, and guide the up-and-down air outlet direction of the air outlet 12, namely change the pitching angle of the air outlet air flow.

As shown in fig. 7, the housing 10 defines an accommodating space for accommodating main body parts of the wall-mounted air conditioner indoor unit, including the blower fan 40, the indoor heat exchanger 30, the controller, and the like. The indoor heat exchanger 30 and the throttle device are connected with a compressor, an outdoor heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. In the case of the heat pump type air conditioner, the indoor heat exchanger 30 functions as an evaporator in the cooling mode. In the heating mode, the indoor heat exchanger 30 functions as a condenser. The housing 10 may be provided with an air inlet 11 for introducing indoor air. The housing 10 also defines an air duct 15. Under the action of the fan 40, indoor air enters the shell 10 through the air inlet 11, and after forced convection heat exchange with the indoor heat exchanger 30 is completed, heat exchange airflow is formed, and the air is guided by the air duct 15 and blown out from the outlet of the air duct 15. The housing 10 may be generally elongated in a horizontal transverse direction along a length direction, and the air inlet 11 is generally disposed at a top of the housing 10. The air duct 15 is typically a through-flow air duct, and the fan 40 is typically a through-flow fan.

For the vertical air conditioner indoor unit, the air outlet and the air deflector can be in a vertical strip shape with the length direction along the vertical direction, so that the air outlet can be opened and closed and/or the transverse air outlet direction of the air outlet can be guided by rotating around the vertical axis.
