Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an indoor unit with a movable panel and an air conditioner. Background Art

[0002] Air conditioners are one of the essential household appliances for people's living, and people's requirements for the comfort of air conditioners are also getting higher and higher. There are two common panel structures for indoor units. One is that the panel structure is immovable and cannot realize the opening of the panel for air outlet. The other is that the panel structure is movable, and the air volume can be increased after the panel is opened.

[0003] Most of the movable panels in the prior art drive a whole panel to move by using a power mechanism. The movement mode of the driven panel is complex and not easy to operate, and the movement track of the panel is single. On the other hand, due to the setting of the power mechanism in the existing movable panel, when it is necessary to clean the filter screen, the panel cannot be directly turned over, and the opening amplitude of the panel is limited, and it is necessary to disassemble the panel, resulting in low efficiency. Summary of the Invention

[0004] The problem solved by the present invention is the problem that the movable panel in the prior art has a complex movement mode, a single movement track of the panel, and is not easy to operate.

[0005] To solve the above problems, a first aspect of the present invention provides an indoor unit with a movable panel, including a panel, a middle frame, and a first air outlet provided on the middle frame. The panel includes a first panel and a second panel that are movably connected, and the first panel is rotatably connected to the middle frame; the movement of the first panel can drive the second panel to move, so as to open or close the first air outlet.

[0006] By providing a first panel and a second panel that are movably connected, and using the movement of the first panel to drive the second panel to move, the present invention has a simple movement mode and is easy to operate; and the relative movement of the two panels can realize a variety of movement tracks, with high flexibility.

[0007] Further, the middle frame and the first panel are connected by a first shaft-hole component, and the first panel and the second panel are connected by a second shaft-hole component to realize the rotational connection between the middle frame and the first panel and the movable connection between the first panel and the second panel.

[0008] Further, the middle frame further includes a second air outlet, and the air deflector can be rotated to open the second air outlet.

[0009] Further, the first air outlet is located on the side surface where the middle frame and the panel cooperate, and the second air outlet is located on the bottom surface of the middle frame; by controlling the movement of the panel and the air deflector under different working conditions, the air supply effects of "showering cooling" during cooling and "carpet heating" during heating are realized, improving the comfort of air conditioner use.

[0010] Furthermore, the first panel is moved by a power mechanism, which includes gears and racks that cooperate with each other and a motor that drives the gears to move. The transmission function is achieved by simple gears and racks, and the transmission efficiency is high and easy to implement.

[0011] Furthermore, the power mechanism also includes a first cover body and a second cover body that enclose the gear and the rack, a guide rail is provided between the first cover body and the second cover body, and guide grooves that cooperate with the guide rail are provided on both sides of the rack. The rack can move along the guide rails of the first cover body and the second cover body. Using the cover body to enclose the gear and rack mechanism will not affect other structures inside the middle frame, and the reliability is higher.

[0012] Furthermore, a slot is provided at the end of the rack near the first panel, and a stop pin structure is provided on the first panel. The rack and the first panel are connected through the slot and the stop pin structure. When the first panel is driven to move, the stop pin structure can slide in the slot to make the movement of the first panel more flexible.

[0013] Furthermore, the power mechanism is provided in two groups, which are respectively installed in grooves on two side surfaces of the middle frame parallel to its width direction. The power mechanisms on both sides are provided to make the panel move more smoothly.

[0014] Furthermore, a first buckle is provided on the second panel, a slide groove is provided in the middle frame, and a second buckle engaged with the first buckle is provided at the bottom of the slide groove. The second panel is engaged with the middle frame through the first buckle and the second buckle to close the first air outlet.

[0015] Furthermore, when the first panel drives the second panel to move, the first buckle can be detached from the second buckle and the slide groove, so that the lower end of the second panel is detached from the middle frame, and the first panel and the second panel are turned over as a whole to open the first air outlet, further realizing the installation and removal of the filter.

[0016] Furthermore, bearing holes are provided at both ends of the first buckle in the length direction, and bearings are installed on the bearing holes. The bearings can slide along the slide groove after the first buckle is detached from the second buckle; the bearings can slide in the slide groove to reduce friction resistance, so that the lower end of the second panel does not detach from the middle frame, thereby realizing a small opening of the first air outlet by the panel.

[0017] A second aspect of the present invention provides an air conditioner, comprising the indoor unit described above. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0029] As Figure 1 shown, an indoor unit with a movable panel provided by an embodiment of the present invention, and an air conditioner including the indoor unit are provided.

[0030] The indoor unit includes a panel 10, a middle frame 20, an air deflector 30, and further includes a power mechanism 40 that can drive the panel 10 to move. The middle frame has a first air outlet 50 and a second air outlet 60. The first air outlet 50 is located on the side surface where the middle frame 20 cooperates with the panel 10, and the second air outlet 60 is located on the bottom surface of the middle frame 20;

[0031] Among them, in combination with Figure 7As shown in the figure, the panel 10 includes a first panel 11 and a second panel 12 that are movably connected. The first panel 11 and the second panel 12 are connected by a second shaft-hole component 17. Among them, the shaft or hole of the second shaft-hole component 17 is provided at the top end of the second panel 12, and the hole or shaft of the shaft-hole component 17 is provided at the bottom of the first panel 11. In addition, the first panel 11 is rotatably connected to the middle frame 20 by a first shaft-hole component 16. Among them, the shaft or hole of the first shaft-hole component 16 is provided at the top end of the first panel 11, and the hole or shaft of the first shaft-hole component 16 is provided at the top end of the middle frame 20.

[0032] When one end of the first panel 11 rotates around the middle frame 20, it can drive the second panel 12 to move, so as to open or close the first air outlet 50. The rotation of the air deflector 30 can open or close the second air outlet 60.

[0033] In the above, by setting the first panel 11 and the second panel 12 that are movably connected, and using the movement of the first panel 11 to drive the movement of the second panel 12, the movement mode is simple and easy to operate; and the relative movement of the two panels can achieve a variety of movement trajectories, with high flexibility.

[0034] Preferably, the power mechanism 40 includes:

[0035] A gear 41, connected to the output shaft of the motor 43;

[0036] A rack 42, meshing with the gear 41. Guide grooves 47 are provided on both sides of the rack 42;

[0037] A motor 43, fixed on the middle frame 20. The motor 43 is preferably a stepper motor;

[0038] A first cover 44 and a second cover 45. The rack 41 and the gear 42 are arranged in the space enclosed by the first cover 44 and the second cover 45. Using the cover structure to enclose the gear-rack mechanism will not affect other structures inside the middle frame, and the reliability is higher; preferably, guide rails 46 that cooperate with the guide grooves 47 are provided on the sides of the first cover 44 and the second cover 45 facing the rack 42. The guide rails 46 are located between the first cover 44 and the second cover 45;

[0039] Therefore, the motor 43 can drive the gear 41 to rotate, and the gear 41 can drive the rack 42 to move along the guide rails 46 of the first cover 44 and the second cover 45.

[0040] Such as Figure 3As shown, the power mechanism 40 is connected to the first panel 11. Two slot holes 47 are provided at the end of the rack 42 close to the first panel 11, and the first panel 11 is provided with a retaining pin structure 13. The rack 42 and the first panel 11 are connected by inserting the retaining pin structure 13 into the slot holes 47. When the gear 41 drives the rack 42 to move along the guide rail 46, the first panel 11 can be driven to rotate outward around the middle frame 20, thereby driving the second panel 12 to move.

[0041] Preferably, two sets of the power mechanism 40 are provided and are respectively installed in the grooves on both sides of the middle frame 20 parallel to its width direction. By setting the power mechanisms on both sides to realize the movement of the panel, the movement of the panel can be made more stable and reliable.

[0042] As Figure 5 、 Figure 6 As shown, a first buckle 14 is provided on the second panel 12, and a second buckle 22 cooperating with the first buckle 14 is provided on the middle frame 20. In the closed state of the panel 10, the first buckle 14 and the second buckle 22 are buckled together.

[0043] In addition, a sliding groove 21 is provided on the middle frame 20, and the second buckle 22 is located at the bottom of the sliding groove 21. When the first panel 11 drives the second panel 12 to move upward, the first buckle 14 can be disengaged from the second buckle 22 and move in the sliding groove 21, so that the lower end of the second panel 12 fits the middle frame 20, and the second panel 12 does not disengage from the middle frame 20 during the movement of the second panel 12, realizing a small opening of the first air outlet of the panel.

[0044] As Figure 8 As shown, preferably, bearing holes are provided at both ends in the length direction of the first buckle 14, and the middle part of the first buckle 14 is engaged with the second buckle 22. Bearings 15 can be installed on the bearing holes, and the bearings 15 can slide along the sliding groove 21 after the first buckle 14 is disengaged from the second buckle 22. With such a setting, when the first buckle 14 moves in the sliding groove 21, the bearings 15 contacting the sliding groove 21 can reduce the frictional resistance, making the movement of the second panel 12 smoother.

[0045] The movable panel of the indoor unit of the present invention has two moving forms:

[0046] (1) As Figure 3The figure shows a sectional view of the first form of panel movement. The specific movement process of the panel 10 is as follows: The power mechanism 40 connected to the first panel 11 drives the first panel 11 to move outward around the middle frame 20, thereby driving the second panel 12 movably connected to the first panel 11 to move upward. The first buckle 14 provided on the second panel 12 directly slides into the chute 21 of the middle frame 20 under the action of the upward force and moves within the chute 21. During this process, the lower end of the second panel 12 always fits against the middle frame.

[0047] (2) As Figure 4 The figure shows a sectional view of the second form of panel movement. The specific movement process of the panel 10 is as follows: By manual operation, the first buckle 14 is disengaged from the second buckle 22 and the chute 21 towards the outside of the indoor unit, realizing the overall flip - type opening of the first air outlet 50 of the first panel 11 and the second panel 12. The opening angle of the panel 10 can be freely adjusted. At this time, the filter screen can be installed and removed by opening the panel 10.

[0048] Specifically, the cooperation between the panel 10 and the air deflector 30 under different working conditions is as follows:

[0049] Under the refrigeration working condition:

[0050] When the refrigeration mode is turned on, the air deflector 30 closes the second air outlet 60. The first panel 11 is driven by the power mechanism 40 to rotate around the middle frame 20, thereby driving the second panel 12 to move and opening the first air outlet 50. At this time, since the first air outlet 50 is located on the side of the middle frame 20 and the second air outlet 60 on the bottom surface is in the closed state, the cold air flow discharged from the first air outlet 50 blows horizontally outward. The cold air flow flows towards the upper area of the room. Since the cold air flow has a higher density and will continuously sink, the cold air blowing towards the upper part of the room will descend to quickly reduce the room temperature, achieving the effect of "shower - type cooling".

[0051] When the refrigeration mode is turned off, the motor 43 of the power mechanism 40 rotates in the reverse direction, driving the first panel 11 and the second panel 12 to reset.

[0052] Under the heating working condition:

[0053] The panel 10 closes the first air outlet 50, and the air deflector 30 rotates to open the second air outlet 60. Since the second air outlet 60 is located on the bottom surface of the middle frame 20 and the air deflector 30 rotates to a certain angle, the hot air flow discharged from the second air outlet 60 flows downward. Since the hot air flow has a lower density and will continuously rise, the hot air blowing towards the ground will continuously rise to quickly increase the room temperature, achieving the effect of "carpet - type heating".

[0054] 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 protection scope of the present invention shall be subject to the scope defined by the claims.
