The utility model provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is a split wall-mounted air conditioner or an indoor unit of a central air conditioner, and is used for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic front view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is a schematic view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, when a front panel 20 is in a closed position; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when the front panel 20 is turned to the open position.

As shown in fig. 1 to 3, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and a front panel 20.

The front side of the housing 10 is open. The housing 10 is elongated with its longitudinal direction parallel to the horizontal transverse direction, and the longitudinal direction thereof is marked as the x direction in fig. 1. The casing 10 defines an accommodation space in which other components of the wall-mounted air conditioning indoor unit are accommodated. Specifically, a heat exchanger, a fan, and a filter screen may be disposed in the housing 10. The top of the casing 10 may be provided with an air inlet, and the heat exchanger, the throttling device, a compressor, a condenser and other refrigeration elements arranged in the air conditioner outdoor unit are connected through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan, indoor air enters the inside of the casing 10 through the air inlet, and after the forced convection heat exchange with the heat exchanger is completed, heat exchange air is formed and enters the air duct, and then the air is blown to the indoor through the air outlet of the casing 10, so that the indoor air is adjusted. The fan is preferably a cross flow fan with its axis parallel to the length of the housing 10 and is located at the entrance to the air duct. The heat exchanger may be a three-stage heat exchanger. The filter screen sets up the air inlet side at the heat exchanger, specifically front side and upside.

The front panel 20 is mounted to the housing 10 to be turnable between a closed position and an open position. The housing is an elongated shape whose length direction is parallel to the length direction of the housing 10, and may be a rectangular plate or an arc plate bent in the width direction as a whole, or an elongated shape of another shape. In the closed position, the front panel 20 has an inner surface 201 standing rearward on the front side of the housing 10 to cover the front side of the housing 10. At this time, the outer surface 202 of the front panel 20 constitutes the front appearance of the wall-mounted air conditioning indoor unit. The front panel 20 of the wall-mounted air conditioner indoor unit is in a closed position in a normal state such as normal operation and shutdown. In the open position, the front panel 20 is turned over above the housing 10 with its inner surface 201 facing downward so that the front side of the housing 10 is open. When it is desired to open the front panel 20 for filter screen removal, or other machine removal operations, the front panel 20 may be flipped to the open position.

The pivotal axis setting of current air conditioner front panel is at the topside of front panel usually, makes the front panel can rotate forward and open certain acute angle, but the opening angle of front panel is too little, and the user need lift the front panel and just can dismantle the filter screen, and operation experience is relatively poor. Different from this kind of current scheme, in the embodiment of the utility model provides an in, when front panel 20 was in the open position, its inner surface 201 was located the casing 10 top down, kept away from the place ahead region of casing 10 completely, and this makes its opening angle reach the biggest, and the filter screen of user's dismantlement casing 10 inside of facilitating the use more. Moreover, the front panel 20 is located above the housing 10 after being opened, for example, horizontally leans against the upper surface of the housing 10, and the user does not need to lift the front panel, so that the user saves more labor and the operation experience is better.

In some embodiments, as shown in fig. 2 and 3, the wall-mounted air conditioning indoor unit further includes at least one guide 50. Each guide 50 is provided at the front upper corner of the housing 10. A wall-mounted indoor air conditioner configured to: during the flip-open of the front panel 20, it is turned around the upper front corner of the housing 10 and its inner surface 201 is simultaneously moved against the guide 50 so that the front panel 20 is positioned directly above the housing 10 when in the open position. Specifically, the flip open or close process of the front panel 20 includes rotation about the upper front corner of the housing 10 and translation along the guide 50, resulting in a compound motion without disengaging the upper front corner of the housing 10 during the motion. This enables the front panel 20 to be smoothly and accurately turned over right above the housing 10.

Preferably, two guide members 50 are provided such that the two guide members 50 are respectively connected to both end portions of the front panel 20 in the longitudinal direction, so as to make the force applied to the front panel 20 more uniform. Of course, three, four or more guides 50 may be provided to be aligned along the length of the front panel 20.

In some embodiments, as shown in fig. 2 and 3, each guide 50 includes a fixed portion 51 and a rotating portion 52. The fixed portion 51 is fixed to the housing 10, the rotating portion 52 is rotatably connected to the fixed portion 51 about an axis X5 parallel to the lateral direction of the housing 10, the front panel 20 is connected to the rotating portion 52 in a translatable manner in its own width direction (y direction) (when the front panel 20 is in the closed position, its width direction y is parallel to the vertical direction), that is, the front panel 20 can only translate relative to the rotating portion 52 in its width direction under the constraint of the rotating portion 52, and the degrees of freedom in the other directions relative to the rotating portion 52 and the degrees of freedom in rotation relative to the rotating portion 52 are constrained. In this way, during the flip-open or close of the front panel 20, it is made to be able to rotate only with the rotating portion 52 while sliding relative to the rotating portion 52. That is, the conforming movement of the front panel 20 includes rotation about X5 and translational sliding movement relative to the rotating portion 52.

FIG. 4 is a schematic view of an alternative construction of the guide member; FIG. 5 is a schematic view of the back structure of the front panel;

fig. 6 is a schematic view of the engagement state of the rotating portion and the front panel.

Fig. 4 and 6 illustrate a preferred coupling structure of the guide 50 to the front panel 20. As shown in fig. 4 to 6, a plurality of slide rails 21 extending in the width direction (y direction) of the front panel 20 may be formed on the inner surface 201 of the front panel 20, and the slide rails 21 may be formed integrally with the main body of the front panel 20 to protrude from the inner surface 201 of the front panel 20. Correspondingly, each rotating portion 52 is provided with a plurality of sliding slots 522, and each sliding rail 21 is slidably mounted in one sliding slot 522 to allow the front panel 20 to slide relative to the rotating portion 52. Obviously, the number of the sliding slots 522 and the number of the sliding rails 21 are the same as the number of the guide members 50.

Referring to fig. 6, the cross section of the slide rail 21 may be made to be "T" shaped, and the cross sectional shape of the slide groove 522 matches the cross sectional shape of the slide rail 21. The T-shaped matching structure of the slide rail 21 and the slide groove 522 can guide the slide rail 21 to only translate along the length direction of the slide groove 522, and the freedom degree of movement along other directions and the freedom degree of rotation relative to the rotating part 52 are both restricted, so that the structure is ingenious.

In some embodiments, referring to fig. 2 and 3, the fixing portion 51 may be disposed on the top of the housing 10, and further, the fixing portion 51 may be a plate shape disposed horizontally. When the front panel 20 is in the closed position, the top edge of the rear surface of the rotating portion 52 is rotatably connected to the top edge of the front end surface of the fixed portion 51, that is, the rotation axis X5 of the two is close to the top edge of the rear surface of the rotating portion 52 and the top edge of the front end surface of the fixed portion 51, refer to fig. 2. In this way, when the front panel 20 is turned to the open state, as shown in fig. 3, the bottom surface of the sliding slot 522 of the rotating portion 52 is higher than the top surface of the fixing portion 51, so as to avoid the front panel 20 (the inner surface 201 and the bottom surface of the sliding slot 522 have the same height) from interfering with the top surface of the fixing portion 51.

In some embodiments, as shown in fig. 2 and 3, the wall-mounted air conditioning indoor unit further comprises at least one first swivel arm 31. The first end a and the second end B of each first rotating arm 31 are rotatably connected to the front panel 20 and the housing 10, respectively, and the rotation axes X1, X2 are parallel to the transverse direction (X direction) of the housing 10, so that the front panel 20 is turned by the first rotating arm 31.

The number of the first swing arms 31 is preferably two, and the two first swing arms 31 are connected to both ends of the front panel 20 in the longitudinal direction, respectively, so that the force applied to the front panel 20 is more uniform. Of course, three, four or more first swivel arms 31 may be provided.

Further, the wall-mounted air conditioning indoor unit may further include a motor 40, and the motor 40 is mounted to the casing 10 and configured to controllably drive the first rotating arm 31 to rotate, that is, to rotate about the rotation axis X2. Fig. 2 only schematically illustrates the motor 40 in a broken line quadrangle. For the embodiment in which a plurality of second rotating arms 32 are provided, a plurality of motors 40 may be provided, or only one motor 40 may be provided, and the respective second rotating arms 32 are connected by a linkage shaft to achieve linkage. The motor 40 is connected to the air conditioner main control panel to receive control thereof. The user sends a control command to the main control panel through a remote controller or other control terminals to drive the motor to rotate forward or backward so as to drive the front panel 20 to open or close. This realizes automation of the opening/closing process of the front panel 20, makes the user operation simpler and labor-saving, and also satisfies the requirement of the appliance intellectualization. Of course, in some alternative embodiments, the motor may not be provided, and the front panel 20 may be manually flipped.

In some embodiments, as shown in fig. 2 and 3, the first end a of the first pivot arm 31 is connected to the lower end of the front panel 20 when the front panel 20 is in the closed position. In this way, when the front panel 20 is turned to the open position, the first end a of the first pivot arm 31 is located at the front side region of the casing 10 so that the front panel 20 can be turned to a more rearward position. It will be appreciated that the axis of rotation X1 of the first end a of the first pivot arm 31 always lies on a circle centered on the axis of rotation X2 of the second end of the first pivot arm 31 when the front panel 20 is rotated between the open and closed positions. Thus, the position of X1 when the front panel 20 is in the open position and the closed position can be designed, and the position of X2 can be determined by this. X2 is located approximately at the center in the height direction of the housing 10.

In some embodiments, the wall-mounted air conditioning indoor unit further includes at least one second rotating arm 32 and at least one spring 35. One end of each second rotating arm 32 is fixed to the second end B of the first rotating arm 31. Obviously, the number of second swivel arms 32 is the same as the number of first swivel arms 31. The rear end of each spring 35 is connected to the housing 10, specifically to the positioning post 36 of the housing 10, and the front end of the spring 35 is connected to the other end of the second rotating arm 32. The second arm 23 may be formed integrally with the first arm 31 as separate sections of a single integral rod. Of course, the two parts can be different parts, and the assembling and the fastening can be carried out at the later stage.

When the front panel 20 is in the closed position, the spring 35 is in a compressed state to apply a forward pressure F1 to the second rotating arm 32, so that the first rotating arm 31 obtains a pretension torque M1 rotating in the (front panel) closing direction (backward), so that the front panel 20 can be more firmly and tightly attached to the housing 10, as shown in fig. 2.

When the front panel 20 is in the open position, the spring 35 is in a stretched state to apply a pulling force F2 to the second pivot arm 32 in a rearward direction, so that the first pivot arm 31 obtains a pretension torque M2 that rotates in a (front panel) opening direction (forward) to apply an assisting force for a later closing process of the front panel 20, as shown in fig. 3. It should be noted that this assistance is small and does not cause the front panel 20 to rotate closed without the application of an external force.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
