Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a wall-mounted dustproof indoor unit and an air conditioner. Background Art

[0002] The existing air outlet of the air conditioner discharges air through the air guide door and / or the wind sweeping blades. The indoor users feel a strong wind. In order to improve the comfort, it is necessary to achieve zero wind feeling air outlet. The usual technical means is to set an external air guide plate on the indoor unit, and the external air guide plate is connected to both sides of the shell through a rotating drive structure. However, the external air guide plate with a rotating connection requires a long connecting arm to achieve the connection with both ends of the shell. The rotation of the connecting arm drives the air guide plate to rotate. Since the air guide plate is long and heavy, the drive structure is overloaded when the connecting arm drives the air guide plate to rotate, which is prone to drive structure failure. In addition, when the hard external air guide plate rotates to the air inlet, it cannot effectively cover the air inlet, causing dust to easily enter the indoor unit. Summary of the invention

[0003] In view of this, the present invention aims to provide a wall-mounted dustproof indoor unit and air conditioner to solve the problem in the prior art that the external air guide plate driving structure is prone to failure due to large force and cannot effectively cover the air inlet.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

When the main control module receives a zero-wind-feeling air outlet command, the main control module controls the slider to slide along the slide rail to the upper part of the air outlet, thereby driving the flexible wind shield to half-open to cover the air outlet. The air outlet of the air conditioner is blown into the room after the wind speed is reduced by the flexible wind shield, thereby reducing the wind feeling and improving user comfort; when the main control module receives a normal air outlet command, the main control module controls the slider to stay at the initial position at the lower part of the slide rail, the slider remains stationary, the flexible wind shield is in a retracted state and is wound around the reel and remains motionless, and the air outlet discharges air normally; when the main control module receives a shutdown and dust prevention command, the main control module controls the slider to slide along the slide rail to the rear side of the air inlet, thereby driving the wind shield to be in a fully open state, so that the wind shield basically covers the entire indoor unit, thereby preventing dust from entering the indoor unit.

[0006] Furthermore, the slide rail is arranged at a position of the side panel close to the front panel, the air inlet and the air outlet, so that when the slider slides inside the slide rail, it can selectively drive the wind shield to cover the air outlet, the air inlet and the front panel.

[0007] Furthermore, a storage portion is provided at the lower part of the air outlet and near the rear side, and the wind shield is stored inside the storage portion. The storage portion includes a storage slot and a reel. The storage slot has a slot-like structure. The reel is installed inside the storage slot. The fixed end of the wind shield is fixed on the reel, and the other end of the wind shield is connected to the slider on both sides.

[0008] Furthermore, a limiting window is provided on the front side wall of the storage slot, the limiting window passes through the front side wall, and the wind shield extends outward through the limiting window and is connected to the sliding block.

[0009] Furthermore, a rotating drive member is provided at at least one end of the storage slot, and the rotating drive member is connected to the reel.

[0010] Furthermore, the slider includes a sliding foot, a groove and a connecting portion, the sliding foot forms the bottom of the slider, a groove is arranged on the upper part of the sliding foot, the groove is arranged as a structure concave toward the center, and the connecting portion is arranged on the upper part of the groove.

[0011] Furthermore, the sliding foot is located inside the slide rail, the groove is clamped on the side wall of the slide rail, the connecting portion extends to the outside of the slide rail, and the sliding block is connected to the wind shield through the connecting portion.

[0012] Furthermore, a connecting shaft is provided on the connecting portion, the wind shield is connected to the connecting shaft, the axis of the connecting shaft is perpendicular to the side wall of the slide rail, and the connecting shaft is configured to be a structure that passes through the slider, and at least one end of the connecting shaft is connected to the wind shield.

[0013] Furthermore, a connecting arm is provided on at least one end of the connecting shaft, the connecting arm is perpendicular to the connecting shaft, and the connecting arm can rotate relative to the connecting shaft, and a wind shield is connected to the end of the connecting arm away from the connecting shaft.

[0014] Compared with the prior art, the wall-mounted dustproof indoor unit of the present invention has the following advantages:

[0015] The slide rail is set at the edge of the side panel, so that the distance between the slide rail and the end of the wind shield is shortened, thereby preventing the slider inside the slide rail from being subjected to a large pulling force. At the same time, the wind shield is set to a flexible structure to reduce the weight of the wind shield, thereby fully reducing the failure rate of the slider and the internal driving structure, and at the same time playing a role in dust prevention for the entire machine.

[0016] The present invention also provides an air conditioner, comprising the above-mentioned wall-mounted dustproof indoor unit.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 7 As shown, a wall-mounted dustproof indoor unit includes a housing 200 and an external windshield structure. The housing 200 includes a front panel 230 and side panels 240 arranged at left and right ends. A slide rail 241 is arranged at the edge of at least one side panel 240. The slide rail 241 extends from the lower part of the air outlet 210 to the air inlet 220. The external windshield structure includes a slider 1 and a windshield member 34. The slider 1 is connected to the windshield member 34. The fixed end of the windshield member 34 is fixed at the lower part of the air outlet 210. The slider 1 slides along the slide rail 241 to drive the windshield member 34 to open or retract, selectively covering the air outlet. The windshield is set as a flexible structure. When the main control module receives a zero wind sense air outlet command, the main control module controls the slider to slide along the slide rail 241 to the upper part of the air outlet, thereby driving the flexible windshield to half open to cover the air outlet. The air outlet of the air conditioner is blown indoors after the wind speed is reduced by the flexible windshield, reducing the wind sense and improving the user's comfort. When the main control module receives a normal air outlet command, the main control module controls the slider to stay at the initial position at the bottom of the slide rail, the flexible windshield is in a contracted state, and the air outlet is normally discharged. When the main control module receives a shutdown dust prevention command, the main control module controls the slider to slide along the slide rail to the rear side of the air inlet, thereby driving the windshield to be in a fully open state, so that the windshield basically covers the entire indoor unit, thereby preventing dust from entering the indoor unit. In addition, the slide rail is set at the edge of the side panel, so that the distance between the slide rail and the end of the windshield is shortened, so as to avoid the slider inside the slide rail from being subjected to a large pulling force. At the same time, the windshield is set as a flexible structure to reduce the weight of the windshield, thereby fully reducing the failure rate of the slider and the internal drive structure.

[0030] Furthermore, the slide rail 241 is arranged at a position of the side panel 240 close to the front panel, the air inlet and the air outlet. When the slider 1 slides inside the slide rail 241, it can selectively drive the windshield to cover the air outlet, the air inlet and the front panel. Preferably, two slide rails 241 are provided, which are respectively located at the edges of the two side panels, so that the left and right sides of the windshield are driven by the slider 1, so as to avoid the windshield 34 from being partially stuck when opening or contracting.

[0031] The storage part 3 is provided at the lower part of the air outlet 210 and near the rear side, and the windshield 34 is stored inside the storage part 3. When the windshield 34 is not in use, the windshield 34 is stored inside the storage part 3 to avoid affecting the normal air discharge. Specifically, the storage part 3 includes a storage slot 31 and a reel 32. The storage slot 31 has a slot-shaped structure. The reel 32 is installed inside the storage slot 31. The fixed end of the windshield 34 is fixedly wound on the reel 32. The other end of the windshield 34 is connected to the slider 1 on both sides. When the slider 1 moves, it drives the windshield 34 to be peeled off from the reel 32 layer by layer, so that the windshield 34 is opened.

[0032] Furthermore, a limit window 33 is provided on the front side wall of the storage slot 31, and the limit window 33 passes through the front side wall. The wind shield 34 extends outward through the limit window 33 and is connected to the slider 1. The setting of the limit window serves as a limit guide for the opening and contraction of the wind shield, thereby preventing the wind shield from being entangled and stuck at any part other than the reel when entering and exiting the storage slot.

[0033] Furthermore, a rotating drive member 35 is provided at at least one end of the storage slot 31, and the rotating drive member 35 is connected to the reel 32. When the windshield 34 does not need to be opened, the driving device drives the slider 1 to move toward the storage portion 3, and the rotating drive member 35 drives the reel 32 to rotate, thereby driving the windshield 34 to be stored and wound on the reel, thereby realizing the arrangement and storage of the windshield. Preferably, two rotating drive members 35 are provided, respectively located at the two ends of the reel 32, to ensure that the two ends of the reel rotate synchronously, so that the windshield can keep the two ends synchronized when storing or opening.

[0034] The slider 1 includes a sliding foot 11, a groove 12 and a connecting portion 13. The sliding foot 11 forms the bottom of the slider 1. The groove 12 is arranged on the upper part of the sliding foot 11. The groove 12 is arranged to be a structure concave toward the center. The connecting portion 13 is arranged on the upper part of the groove 12. Therefore, when the slider 1 is installed inside the slide rail 241, the sliding foot 11 is located inside the slide rail 241, the groove 12 is clamped on the side wall of the slide rail 241, the connecting portion 13 extends to the outside of the slide rail 241, and the slider 1 is connected to the windshield 34 through the connecting portion 13. The arrangement of the sliding foot and the groove ensures the stability of the connection between the slider 1 and the slider, prevents the slider from detaching from the inside of the slide rail, and prevents the slider from getting stuck when sliding.

[0035] Furthermore, two grooves 12 are provided, and the two grooves 12 are bilaterally symmetrical, so that when the slider slides, both the left and right sides of the slider slide along the two side arms of the slider, ensuring that the slider slides smoothly.

[0036] Furthermore, a connecting shaft 14 is provided on the connecting portion 13, and the windshield 34 is connected to the connecting shaft 14, so that the sliding block 1 moves to drive the windshield to open. Specifically, the axis of the connecting shaft 14 is perpendicular to the side wall of the slide rail 241, and the connecting shaft 14 is set to a structure that penetrates the sliding block 1, and at least one end of the connecting shaft 14 is connected to the windshield 34, so that the sliding block drives the windshield to open or retract.

[0037] In this embodiment, a connecting arm 2 may be provided on at least one end of the connecting shaft 14, the connecting arm 2 being perpendicular to the connecting shaft 14 and being able to rotate relative to the connecting shaft 14, and a windshield 34 is connected to the end of the connecting arm 2 away from the connecting shaft 14, and by adjusting the angle between the connecting arm 2 and the main body of the slider 1, the distance between the windshield and the indoor unit housing may be adjusted, so that the windshield fits the outer surface of the housing and is fully dustproof. Preferably, a connecting arm 2 may be provided at the end of the connecting shaft 14 away from the center of the housing, so that both connecting arms 2 are located on the outside, so that the windshield is as long as possible not less than the total length of the housing in the left-right direction, thereby providing sufficient protection and covering for the indoor unit housing.

[0038] Furthermore, a connecting ring 21 is set at one end of the connecting arm 2, and a connecting pin 22 is set at the other end. The connecting arm 2 is connected to the connecting shaft 14 through the connecting ring 21. The connecting pin 22 at the other end passes through the connecting arm 2 and is connected to the flexible wind shield 34. The setting of the connecting pin 22 provides a fulcrum for the connection of the wind shield.

[0039] In order to fully explain the specific role of the wind shield structure in this application, the status of each component in different states is described as follows. The air conditioning state includes normal air outlet state, zero wind outlet state and shutdown dustproof state.

[0040] When the indoor unit receives the instruction of normal air outlet state, the main control module controls the slider 1 to remain in the initial position (adjacent to the storage slot and outside the storage slot), the air outlet and the air inlet are both exposed, and most of the wind shield 34 is wound around the reel. At this time, the indoor unit has normal wind outlet.

[0041] When the indoor unit receives the command for zero wind air outlet, the main control module controls the slider 1 to slide along the slide rail until the slider 1 is on both sides of the upper part of the air outlet. At this time, the slider drives the wind shield 34 to cover the outside of the air outlet, and the remaining part of the wind shield is still wound on the reel. The air outlet of the indoor unit is blown into the room after the wind speed is reduced by the wind shield. At this time, the indoor unit achieves zero wind air outlet.

[0042] When the indoor unit receives the command to shut down and prevent dust, the main control module controls the slider 1 to slide along the slide rail until the slider 1 is on both sides of the rear of the air inlet. At this time, the slider drives the wind shield 34 to cover the air outlet, the front panel and the outside of the air inlet, basically covering the entire indoor unit, fully preventing dust from entering the interior of the indoor unit.

[0043] As part of an embodiment of the present invention, an air conditioner is also provided, comprising the above-mentioned wall-mounted dustproof indoor unit.

[0044] 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.
