Wall-mounted dustproof indoor unit and air conditioner

Abstract

The application provides a wall-mounted dustproof indoor unit and an air conditioner, which comprises a shell and an external wind blocking structure. The shell comprises a front panel and side panels arranged at left and right ends. A sliding rail is arranged at the edge of at least one side panel and extends from the lower part of an air outlet to the air inlet. The external wind blocking structure comprises a sliding block and a wind blocking piece. The sliding block is connected to the wind blocking piece. The fixed end of the wind blocking piece is fixed to the lower part of the air outlet. The sliding block slides along the sliding rail to drive the wind blocking piece to open or shrink to selectively cover the air outlet. When receiving a zero wind feeling air outlet instruction, the main control module controls the sliding block to drive the flexible wind blocking piece to open to cover the air outlet. When receiving a normal air outlet instruction, the main control module controls the sliding block to stay at the initial position at the lower part of the sliding rail, and the air outlet normally blows air. When receiving a dustproof shutdown instruction, the main control module controls the sliding block to drive the wind blocking piece to completely open, so that the wind blocking piece basically covers the whole indoor unit, thereby preventing dust from entering the interior of the indoor unit.

Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a wall-mounted dustproof indoor unit and an air conditioner. Background Technology

[0002] Existing air conditioner vents deliver air through deflectors and / or sweeping blades, resulting in a strong draft felt by indoor users. To improve comfort, zero-draft airflow is required. A common technical approach is to install an external air deflector on the indoor unit, connected to both sides of the casing via a rotating drive structure. However, this rotating connection requires a long connecting arm to connect to both ends of the casing. The rotation of the connecting arm drives the air deflector, and due to its length and weight, the drive structure is overloaded when the connecting arm rotates, potentially leading to drive structure failure. Furthermore, the rigid external air deflector, when rotating to the air inlet, cannot effectively cover the inlet, allowing 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 problems of the existing external air guide plate drive structure being prone to failure due to large stress and failing to effectively cover the air inlet.

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

[0005] A wall-mounted dustproof indoor unit includes a housing and an external wind deflector structure. The housing includes a front panel and side panels at the left and right ends. A slide rail is provided at at least one edge of the side panel, extending from the lower part of the air outlet to the air inlet. The external wind deflector structure includes a slider and a wind deflector component. The slider is connected to the wind deflector component, and the fixed end of the wind deflector component is fixed to the lower part of the air outlet. The slider slides along the slide rail to cause the wind deflector component to open or retract to selectively cover the air outlet. When the main control module receives a zero-wind-feel airflow command, it controls the slider to slide along the slide rail to the upper part of the air outlet, thereby causing the flexible wind deflector to partially open and cover the air outlet. The airflow from the air conditioner is then blown into the room after the wind speed is reduced by the flexible wind deflector, reducing the feeling of wind and improving user comfort. When the main control module receives a normal airflow command, it controls the slider to stay at the initial position at the lower part of the slide rail. The slider remains stationary, the flexible wind deflector is in a retracted state and is wound on the roller and remains stationary, and the air outlet discharges air normally. When the main control module receives a shutdown and dust prevention command, it controls the slider to slide along the slide rail to the rear of the air inlet, thereby causing the wind deflector to fully open, so that the wind deflector basically covers the entire indoor unit, preventing dust from entering the indoor unit.

[0006] Furthermore, the slide rail is positioned on the side panel near the front panel, air inlet, and air outlet. This allows the slider to selectively move the baffle to cover the air outlet, air inlet, and front panel as it slides within the slide rail.

[0007] Furthermore, a storage section is provided at the lower part of the air outlet and near the rear side. The wind deflector is stored inside the storage section. The storage section includes a storage groove and a scroll. The storage groove has a groove-shaped structure. The scroll is installed inside the storage groove. The fixed end of the wind deflector is fixed on the scroll. The other end of the wind deflector is connected to the slider on both the left and right sides.

[0008] Furthermore, a limiting window is provided on the front side wall of the storage slot, the limiting window penetrates the front side wall, and the windproof component extends outward through the limiting window and connects with the slider.

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

[0010] Furthermore, the slider includes a sliding foot, a groove, and a connecting part. The sliding foot forms the bottom of the slider, and a groove is provided on the upper part of the sliding foot. The groove is configured to be recessed towards the center, and the connecting part is provided on the upper part of the groove.

[0011] Furthermore, the sliding foot is located inside the slide rail, the groove is engaged with the side wall of the slide rail, the connecting part extends to the outside of the slide rail, and the slider is connected to the wind deflector through the connecting part.

[0012] Furthermore, a connecting shaft is provided on the connecting part, the wind deflector 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 pass through the slider, with at least one end of the connecting shaft connected to the wind deflector.

[0013] Furthermore, a connecting arm is provided at at least one end of the connecting shaft, the connecting arm is perpendicular to the connecting shaft and is rotatable relative to the connecting shaft, and a windshield is connected to the end of the connecting arm away from the connecting shaft.

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

[0015] By placing the slide rail on the edge of the side plate, the distance between the slide rail and the end of the wind deflector is shortened, thus avoiding excessive tensile force on the slider inside the slide rail. At the same time, the wind deflector is made into a flexible structure to reduce its weight, thereby significantly reducing the failure rate of the slider and internal drive structure, while also serving to prevent dust from entering the entire machine.

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

[0017] The advantages of the air conditioner mentioned above over the existing technology are the same as those of the wall-mounted dustproof indoor unit, and will not be repeated here. Attached Figure Description

[0028] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] like Figures 1-7 As shown, a wall-mounted dustproof indoor unit includes a housing 200 and an external wind deflector structure. The housing 200 includes a front panel 230 and side panels 240 disposed at the left and right ends. A slide rail 241 is provided at the edge of at least one side panel 240, extending from the lower part of the air outlet 210 to the air inlet 220. The external wind deflector structure includes a slider 1 and a wind deflector 34. The slider 1 is connected to the wind deflector 34, and the fixed end of the wind deflector 34 is fixed to the lower part of the air outlet 210. The slider 1 slides along the slide rail 241, causing the wind deflector 34 to open or retract, selectively covering the air outlet. The wind deflector is designed as a flexible structure. When the main control module receives a zero-wind-feel airflow command, it controls the slider to slide along the slide rail 241 to the upper part of the air outlet, thereby causing the flexible wind deflector to partially open and cover the air outlet. The airflow from the air conditioner is reduced in speed by the flexible wind deflector before being blown into the room, reducing the wind sensation and improving user comfort. When the main control module receives a normal airflow command, it controls the slider to stay at the initial position at the lower part of the slide rail, the flexible wind deflector is in a retracted state, and the air outlet discharges air normally. When the main control module receives a shutdown and dust prevention command, it controls the slider to slide along the slide rail to the rear side of the air inlet, thereby causing the wind deflector to fully open, so that the wind deflector basically covers the entire indoor unit, preventing dust from entering the indoor unit. In addition, the slide rail is located at the edge of the side panel, which shortens the distance between the slide rail and the end of the wind deflector, avoiding excessive tensile force on the slider inside the slide rail. At the same time, the flexible structure of the wind deflector reduces its weight, thereby significantly reducing the failure rate of the slider and internal drive structure.

[0030] Furthermore, the slide rail 241 is positioned on the side panel 240 near the front panel, air inlet, and air outlet. This allows the slider 1 to selectively drive the wind deflector to cover the air outlet, air inlet, and front panel when sliding inside the slide rail 241. Preferably, two slide rails 241 are provided, located at the edges of the two side panels respectively, so that both sides of the wind deflector are driven by the slider 1, preventing local jamming of the wind deflector 34 when opening or closing.

[0031] A storage section 3 is provided at the lower part of the air outlet 210 and near the rear side. The wind deflector 34 is stored inside the storage section 3. When the wind deflector 34 is not in use, it is stored inside the storage section 3 to avoid affecting normal airflow. Specifically, the storage section 3 includes a storage groove 31 and a scroll 32. The storage groove 31 has a groove-shaped structure. The scroll 32 is installed inside the storage groove 31. The fixed end of the wind deflector 34 is fixedly wound around the scroll 32. The other end of the wind deflector 34 is connected to the slider 1 on both sides. When the slider 1 moves, it causes the wind deflector 34 to peel off from the scroll 32 layer by layer, thereby opening the wind deflector 34.

[0032] Furthermore, a limiting window 33 is provided on the front side wall of the storage slot 31. The limiting window 33 penetrates the front side wall, and the wind deflector 34 extends outward through the limiting window 33 and connects with the slider 1. The setting of the limiting window plays a limiting and guiding role in the opening and closing of the wind deflector, so as to prevent the wind deflector from getting tangled and stuck in parts other than the scroll when entering and leaving the storage slot.

[0033] Furthermore, a rotary drive 35 is provided at least one end of the storage slot 31. The rotary drive 35 is connected to the scroll 32. When the windshield 34 does not need to be opened, the drive device drives the slider 1 to move towards the storage section 3. At the same time, the rotary drive 35 drives the scroll 32 to rotate, thereby causing the windshield 34 to be stored and wound on the scroll, thus realizing the organization and storage of the windshield. Preferably, there are two rotary drive 35s, located at both ends of the scroll 32 respectively, to ensure that both ends of the scroll rotate synchronously, so that the windshield can maintain synchronization at both ends when stored or opened.

[0034] The slider 1 includes a sliding foot 11, a groove 12, and a connecting part 13. The sliding foot 11 forms the bottom of the slider 1. The groove 12 is provided on the upper part of the sliding foot 11, and the groove 12 is designed to be recessed towards the center. The connecting part 13 is located on the upper part of the groove 12. Thus, 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 engaged with the side wall of the slide rail 241, and the connecting part 13 extends to the outside of the slide rail 241. The slider 1 is connected to the windproof member 34 through the connecting part 13. The sliding foot and the groove ensure the stability of the connection between the slider 1 and the slide rail, prevent the slider from detaching from the slide rail, and prevent the slider from jamming during sliding.

[0035] Furthermore, there are two grooves 12, and the two grooves 12 are symmetrical, so that the slider slides along the two arms of the slider on both sides when sliding, ensuring that the slider slides smoothly and steadily.

[0036] Furthermore, a connecting shaft 14 is provided on the connecting part 13, and the wind deflector 34 is connected to the connecting shaft 14, so that the slider 1 moves to drive the wind deflector 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 configured to pass through the slider 1. At least one end of the connecting shaft 14 is connected to the wind deflector 34 so that the slider drives the wind deflector to open or retract.

[0037] In this embodiment, a connecting arm 2 can be provided on at least one end of the connecting shaft 14. The connecting arm 2 is perpendicular to the connecting shaft 14 and can rotate relative to the connecting shaft 14. A wind deflector 34 is connected to the end of the connecting arm 2 away from the connecting shaft 14. By adjusting the angle between the connecting arm 2 and the body of the slider 1, the distance between the wind deflector and the indoor unit housing can be adjusted, thereby making the wind deflector fit against the outer surface of the housing and effectively preventing dust. Preferably, the connecting arm 2 can 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 outer side, thereby making the wind deflector as long as possible in the left-right direction as possible not less than the total length of the housing, thus providing sufficient protection and coverage for the indoor unit housing.

[0038] Furthermore, a connecting ring 21 is provided at one end of the connecting arm 2, and a connecting pin 22 is provided at the other end. The connecting arm 2 is connected to the connecting shaft 14 through the connecting ring 21, and the connecting pin 22 at the other end passes through the connecting arm 2 and is connected to the flexible windbreak 34. The connecting pin 22 is configured to provide a fulcrum for the connection of the windbreak.

[0039] To fully illustrate the specific function of the windbreak structure in this application, the states of each component under different conditions are described below. The air conditioning states include normal airflow, zero-wind-feel airflow, and dust-proof shutdown.

[0040] When the indoor unit receives the command for normal airflow, the main control module controls the slider 1 to remain in the initial position (adjacent to the storage compartment and located outside the storage compartment), both the air outlet and the air inlet are exposed, and most of the wind deflector 34 is wrapped around the roller. At this time, the indoor unit delivers normal airflow.

[0041] When the indoor unit receives the command for zero-wind-feel airflow, 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 deflector 34 to cover the outside of the air outlet, and the remaining part of the wind deflector is still wrapped on the roller. The air outlet of the indoor unit is blown into the room after the wind speed is reduced by the wind deflector. At this time, the indoor unit achieves zero-wind-feel airflow.

[0042] When the indoor unit receives the command to turn off and enter the dust prevention state, 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 deflector 34 to cover the air outlet, front panel and the outside of the air inlet, basically covering the entire indoor unit and fully preventing dust from entering the interior of the indoor unit.

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

[0044] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
