Description

Indoor unit with movable air guide plate and air conditioner

Technical Field

The utility model relates to the technical field of air conditioning, in particular to an indoor unit with a movable air guide plate and an air conditioner.

Background Art

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. For example, the prior art discloses a patent for a wind shield device and an air conditioner for an air conditioner. In the prior art, 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 longer support arm to achieve the connection with both ends of the shell. The rotation of the support arm drives the air guide plate to rotate. Since the air guide plate is long and heavy, the drive structure is overloaded when the long connecting arm drives the air guide plate to rotate, and the drive structure is prone to failure.

Utility Model Content

In view of this, the utility model aims to provide an indoor unit and an air conditioner with a movable air guide plate to solve the problem in the prior art that a rotatably connected external air guide plate is prone to cause a driving structure failure when rotating.

In order to achieve the above object, the technical solution of the utility model is implemented as follows:

An indoor unit with a movable wind deflector comprises a shell and an external wind shield structure, wherein the shell comprises a front panel and side panels arranged at left and right ends, slide rails are arranged at the edges of the side panels, and the slide rails extend from the lower part of the air outlet to the air inlet, and the external wind shield structure comprises a slider and an external wind shield, the slider is connected to the external wind shield, and the slider drives the external wind shield to move to selectively cover the air outlet. When the main control module receives a zero-wind-feeling air outlet command, the outer wind shield is required to adjust the air volume, and the main control module controls the slider to slide along the slide rail so that the outer wind shield covers the air outlet. The air outlet of the air conditioner is blown into the room after the wind speed is reduced by the outer wind shield, thereby reducing the wind feeling and improving user comfort. When the main control module receives a normal air outlet command, the outer wind shield is not required to adjust the air volume. The main control module controls the slider to stay near the upper part of the slide rail, the outer wind shield is on the front side of the front panel, 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 air inlet, thereby driving the outer wind shield to cover the air inlet, thereby preventing dust from entering the indoor unit.

Furthermore, the slide rail is arranged on the side panel near the front panel, and the starting end of the slide rail is located at the upper part of both ends of the air outlet, and the end of the slide rail is arranged at the front side of both ends of the air inlet.

An indoor unit with a movable wind deflector includes a housing 200 and an external wind shielding structure 100. 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 the side panel 240. The slide rail 241 extends from the lower part of the air outlet 210 to the air inlet 220. The external wind shielding structure includes a slider 1 and an external wind shielding plate 3. The slider 1 is connected to the external wind shielding plate 3. The slider 1 drives the external wind shielding plate 3 to move to selectively cover the air outlet. A microporous structure is arranged on the outer wind shield 3. When the main control module receives a zero-wind-feeling air outlet command, the outer wind shield 3 needs to adjust the air volume. The main control module controls the slider to slide along the slide rail 241 so that the outer wind shield 3 covers the air outlet 210. The air outlet of the air conditioner is blown into the room after the wind speed is reduced by the outer wind shield 3, thereby reducing the wind feeling and improving the user comfort. When the main control module receives a normal air outlet command, the outer wind shield 3 does not need to adjust the air volume. The main control module controls the slider to stay at a position close to the upper part of the slide rail, the outer wind shield 3 is on the front side of the front panel, 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 air inlet, thereby driving the outer wind shield to cover the air inlet, thereby preventing dust from entering the indoor unit. In addition, the slide rail is arranged at the edge of the side panel. Compared with the prior art which requires the use of a longer support arm, the present invention shortens the distance between the slide rail and the end of the outer wind shield plate, and does not require a longer connecting arm to connect to the outer wind shield plate, thereby avoiding a large pulling force on the slider inside the slide rail, and substantially reducing the failure rate of the slider and the internal driving structure. The slide rail is in an invisible position, which protects the connecting arm and the slider, thereby preventing external dust and debris from affecting the operation of the outer wind shield plate driving device, and the outer wind shield plate moves smoothly.

Furthermore, the slide rail 241 is arranged on the side panel 240 near the front panel, and the starting end of the slide rail 241 is located near the upper part at both ends of the air outlet, and the end of the slide rail 241 is arranged near the front side at both ends of the air inlet. Therefore, after the indoor unit is installed on the wall, the starting end and the end of the slide rail are both a certain distance away from the wall, thereby preventing the outer wind shield from colliding with the wall and causing damage.

The outer wind shield 3 is configured as an arc-shaped plate, so that when the outer wind shield covers the air outlet to reduce the wind feeling, the arc-shaped outer wind shield forms an upturned structure on the front and rear sides of the wind shield, forming an approximate wrapping effect on the air outlet 210, preventing the air from blowing directly into the room without passing through the wind shield and affecting the comfort of indoor users.

Correspondingly, a connecting block 31 is provided inside the outer wind shield 3 . The connecting block 31 is provided inside the outer wind shield 3 and close to both ends. The outer wind shield 3 is connected to the slider via the connecting block 31 .

Specifically, 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 as a structure concave toward the center. The connecting portion 13 is arranged on the upper part of the groove 12. The connecting portion 13 is connected to the connecting block of the outer wind shield 3. 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 outer wind shield 3 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. Furthermore, a rib 242 is provided on the left and right side walls of each slide rail 241, and the two ribs 242 of the same slide rail 241 are arranged to be close to each other, thereby forming a structure that is wide inside and narrow outside inside the slide rail 241, which matches the lower shape of the slider 1 and prevents the slider 1 from detaching from the inside of the slide rail 241.

Furthermore, the same slider 1 is provided with two grooves 12, 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.

Furthermore, a connecting shaft 14 is provided on the connecting portion 13, and the outer wind shield 3 is connected to the connecting shaft 14 through the connecting block 31, so that the slider 1 moves to drive the outer wind shield 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 slider 1, and at least one end of the connecting shaft 14 is connected to the outer wind shield 3, so that the slider drives the outer wind shield to open or retract.

In this embodiment, a connecting arm 2 may be provided on at least one end of the connecting shaft 14 . The connecting arm 2 is perpendicular to the connecting shaft 14 , and one end of the connecting arm 2 away from the connecting shaft 14 is connected to the connecting block 31 of the outer wind shield 3 .

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. The connecting pin 22 at the other end passes through the connecting arm 2 and is connected to the connecting block of the outer wind shield 3. The setting of the connecting pin 22 provides a fulcrum for the connection of the outer wind shield. Correspondingly, the connecting blocks 31 on the outer wind shield 3 are provided in two groups, which are respectively located on the inner side of the outer wind shield 3 and close to the two ends. Each group of connecting blocks 31 includes two corner blocks, which are arranged opposite to each other. Connecting holes are provided on the two corner blocks, and the centers of the two connecting holes are aligned. The two ends of the connecting pin 22 pass through the two corner blocks to realize the fixed connection between the connecting arm 2 and the outer wind shield.

In this embodiment, the connecting arm 2 is rotatably connected to the connecting shaft 14, so that the connecting arm 2 can rotate relative to the connecting shaft 14, and the outer wind shield 3 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 slider 1 body, the distance between the outer wind shield 3 and the indoor unit housing can be adjusted, so that the outer wind shield fits the outer surface of the housing and is fully dustproof. That is, when the outer wind shield 3 is not needed to adjust the air volume, the slider 1 is located at the end of the slide rail 241 close to the air inlet 220, and the driving device drives the connecting arm 2 to rotate to basically overlap with the slider, reducing the angle between the connecting arm and the slider, so that the outer wind shield and the front panel structure are compact. Preferably, the connecting arm 2 can be set at the end of the connecting shaft 14 away from the center of the housing, so that the two connecting arms 2 are both located on the outside, so that the outer wind shield is as much as possible not less than the total length of the housing in the left and right direction, thereby providing sufficient protection and covering for the indoor unit housing.

In order to fully explain the specific role of the external 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 dust prevention state.

When the indoor unit receives the instruction of normal air outlet state, the main control module controls the slider 1 to stay at the position near the upper part of the slide rail, the air outlet and the air inlet are both exposed, and the outer wind shield 3 is located on the front side of the front panel 230. At this time, the indoor unit has normal wind outlet.

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 at the air outlet or the upper sides of the air outlet. At this time, the slider drives the outer wind shield 3 to cover the outside of the air outlet. 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.

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 air inlet. At this time, the slider drives the outer wind shield 3 to cover the outside of the air inlet, and at the same time drives the rotation of the driving connecting shaft or the user manually presses the outer wind shield to drive the connecting arm 2 to rotate until it basically overlaps with the slider, thereby reducing the angle between the connecting arm and the slider, making the outer wind shield and the front panel structure compact, and fully preventing dust from entering the indoor unit.

As part of the embodiments of the present utility model, an air conditioner is also provided, comprising the indoor unit with the movable air guide plate as described above.

Although the utility model is disclosed as above, the utility model 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 utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
