Description

Technical Field

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

[0002] Wall-mounted air conditioners are widely used. Since the indoor unit of a wall-mounted air conditioner is usually installed in a fixed position, in order to make the indoor temperature uniform, air needs to be supplied to different areas of the room. Usually, an air guide plate is provided at the air outlet of the indoor unit of the wall-mounted air conditioner, and the air supply is guided by the swing of the air guide plate.

[0003] For example, when the air conditioner is running the cooling function, in order to avoid direct blowing of cold air, a wind shield is set at the middle frame position. The wind shield is adjusted to move on the middle frame to change its blocking effect on the cold air blown out of the air outlet to the indoor environment, so as to improve the user experience.

[0004] However, there is at least one of the following problems in the related technology: although the traditional wind shield can achieve the effect of preventing direct blowing of cold air, the existence of the wind shield also blocks the air conditioner from blowing toward a distant location, making it impossible to improve the heat exchange efficiency between the air conditioner and the indoor environment in a short time while ensuring that direct blowing of cold air is avoided, resulting in a reduction in the user experience. Summary of the invention

[0005] The technical problem solved by the present invention is that although the traditional wind shield can achieve the effect of preventing direct blowing of cold air, the existence of the wind shield also blocks the air blowing of the air conditioner toward a distant location, making it impossible to improve the heat exchange efficiency between the air conditioner and the indoor environment in a short time while ensuring preventing direct blowing of cold air, resulting in a reduction in the user experience.

[0006] To solve the above problems, the present invention provides an indoor unit, comprising: a middle frame shell, a panel is installed on one side of the middle frame shell, the panel is provided with a first air outlet, and a second air outlet is provided below the middle frame shell; a wind shield assembly, the wind shield assembly is movably connected to the panel to switch between a first relative position and a second relative position; wherein, when the wind shield assembly is in the first relative position, the wind shield assembly blocks the first air outlet and exposes the second air outlet; when the wind shield assembly is in the second relative position, the wind shield assembly blocks the second air outlet and exposes the first air outlet.

[0007] Compared with the prior art, the technical effects achieved by adopting the technical scheme are as follows: on the one hand, by arranging the first air outlet on the panel, heat exchange with the indoor environment is achieved simultaneously through the first air outlet and the second air outlet, thereby improving the heat exchange efficiency of heat exchange with the indoor environment only through the single second air outlet; on the other hand, combined with the difference in position of the first air outlet compared to the second air outlet in the indoor unit, specifically, the first air outlet is arranged at a high position, and its air outlet direction is also blown to the corresponding high position of the indoor environment, so that while it realizes heat exchange with the indoor environment, the cold air blown out from there can form an azimuth dislocation with the user located below it, thereby achieving the effect of avoiding direct blowing of cold air; in addition, combined with the wind shield component, it can flexibly switch between the first relative position and the second relative position, so that on the basis of effectively avoiding direct blowing of cold air, the heat exchange efficiency with the indoor environment is improved at the same time, thereby improving the user experience.

[0008] In one example of the present invention, the wind shield assembly is slidably connected to the panel; wherein, when the wind shield assembly blocks the second air outlet, the wind shield assembly stops the air from the second air outlet in a direction away from the wall-mounted side.

[0009] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: combined with the actual installation situation of the wall-mounted indoor unit, the outlet area of ​​the cold air blown out by the second air outlet is effectively limited to the air outlet range bounded by the wall and the wind shield assembly, thereby weakening the heat exchange efficiency corresponding to the second air outlet and the areas outside the above-mentioned air outlet range, that is, the wind force within the air outlet range is greatly reduced, thereby improving the user experience of users outside the air outlet range.

[0010] In one example of the present invention, a first slide rail is provided at a position of the panel corresponding to the wind shield assembly; and the wind shield assembly is provided with a wind shield plate slidably matched with the first slide rail.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by making the wind shield plate move in the first slide rail, the movement stability and movement efficiency of the wind shield plate are effectively improved.

[0012] In one embodiment of the present invention, the wind deflector is a flexible member; the track of the first slide rail is adapted to the surface curve of the panel.

[0013] Compared with the prior art, the technical effects achieved by adopting this technical solution are: on the one hand, it reduces the increase in the space occupancy rate of the indoor unit during the process of moving the wind shield due to the large deviation between the trajectory of the first sliding rail and the surface curve of the panel; on the other hand, it makes the appearance of the indoor unit change less during the process of moving the wind shield, effectively maintaining the aesthetic appearance of the indoor unit.

[0014] In one embodiment of the present invention, the panel is provided with an installation opening for accommodating the driving assembly, and the windshield is clamped between the first slide rail and the driving assembly; wherein the driving assembly is driven to drive the windshield to move in the first slide rail.

[0015] Compared with the prior art, the technical effects achieved by adopting this technical solution are: on the one hand, the wind shield is driven to move between the first relative position and the second relative position by the driving component, which replaces manual adjustment, improves the adjustment efficiency of the wind shield, and improves the user experience; on the other hand, the shielding effect of the wind shield on the driving component effectively avoids the driving component being exposed to the user's line of sight and reducing the appearance of the indoor unit, while making the indoor unit more concise in appearance.

[0016] In one example of the present invention, the driving assembly includes a driving motor disposed in a middle frame shell and a transmission gear cooperating with the driving motor, and at least a portion of the structure of the transmission gear extends out of the mounting opening; a meshing rack meshing with the transmission gear is provided on one side of the wind shield close to the transmission gear.

[0017] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the windshield moves by means of the meshing of gears and racks, which improves the stability of movement, effectively avoids slipping during transmission, and reduces the noise generated by the windshield during movement.

[0018] In one example of the present invention, either the first slide rail or the panel is provided with a plurality of gear engaging parts, and the plurality of gear engaging parts are arranged sequentially along the direction in which the wind shield assembly moves from the first relative position to the second relative position; the other one is provided with a mating engaging part that is engaged with at least one of the plurality of gear engaging parts; wherein, when the wind shield plate is switched between the first relative position and the second relative position, the mating engaging part is engaged with a corresponding one of the plurality of gear engaging parts.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: in a specific example, the gear engaging member can be a circular arc convex structure, and correspondingly, the matching engaging member is a cylindrical convex structure, so that in the process of adjusting the movement of the wind deflector, the cylindrical convex structure is successively matched with different circular arc convex structures, which prevents the wind deflector from accidentally falling out of the first slide rail during the movement, especially when the indoor unit is in the standby state, by setting the cylindrical convex structure on any one of the multiple circular arc convex structures, it is effectively avoided to fall out of the first slide rail under the action of its gravity. At the same time, the specific state of the wind deflector at this time can be determined according to the gear change sound generated by the cylindrical convex structure hitting the circular arc convex structure during the adjustment of the wind deflector, when the cylindrical convex structure cooperates with different circular arc convex structures due to overcoming the squeezing force from the first slide rail.

[0020] In one example of the present invention, the first sliding rail includes a first rail segment and a second rail segment, the first rail segment is arranged at the first end of the panel along its transverse direction, and the second rail segment is arranged at the second end of the panel along its transverse direction; the first rail segment and / or the second rail segment is provided with a pulley set that rolls with the panel on the side away from the transmission gear.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: specifically, by setting up a pulley group, the friction sound generated by the mutual squeezing of the wind shield and the first slide rail in a surface-to-surface manner is effectively avoided, thereby further improving the user experience and ensuring that the wind shield remains relatively quiet during movement.

[0022] In one example of the present invention, an air inlet is provided at the top of the middle frame shell; the middle frame shell also includes: a second slide rail, the second slide rail is arranged to the top, and the second slide rail cooperates with the first slide rail to allow the wind shield to slide between the two; wherein, when the wind shield slides to the second slide rail, the wind shield covers the air inlet.

[0023] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the air inlet is covered by the wind shield plate, thereby ensuring that dust is prevented from entering the air inlet when the indoor unit is in standby mode.

[0024] On the other hand, the present invention further provides an air conditioner, comprising: an indoor unit as in any of the above examples.

[0025] Compared with the prior art, the technical effect achieved by adopting this technical solution is: it can achieve the corresponding technical effect in any of the above-mentioned technical solutions, which will not be repeated here.

[0026] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0027] (1) On the one hand, by arranging the first air outlet on the panel, heat exchange with the indoor environment is achieved simultaneously through the first air outlet and the second air outlet, thereby improving the heat exchange efficiency of the heat exchange with the indoor environment by only the single second air outlet; on the other hand, combined with the difference in position between the first air outlet and the second air outlet in the indoor unit, specifically, the first air outlet is arranged at a high position, and its air outlet direction is also blown to the corresponding high position of the indoor environment, so that when it achieves heat exchange with the indoor environment, the cold air blown therefrom can be misaligned with the user located below it in terms of azimuth, thereby achieving the effect of avoiding direct blowing of cold air; in addition, combined with the wind shield component, it can flexibly switch between the first relative position and the second relative position, so that on the basis of effectively avoiding direct blowing of cold air, the heat exchange efficiency with the indoor environment is improved at the same time, thereby improving the user experience;

[0028] (2) On the one hand, the windshield is driven by the driving component to move between the first relative position and the second relative position, thereby replacing manual adjustment, improving the adjustment efficiency of the windshield, and improving the user experience; on the other hand, the windshield shields the driving component, effectively preventing the driving component from being exposed to the user's sight and reducing the aesthetic appearance of the indoor unit, and making the indoor unit more concise in appearance;

[0029] (3) The air inlet is covered by a wind shield to prevent dust from entering the air inlet when the indoor unit is in standby mode. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] See also Figure 1 , which is a schematic diagram of the structure of an indoor unit 100 provided in an embodiment of the present invention. The indoor unit 100 includes, for example, a middle frame housing 10 and a wind shielding component. Figure 2-Figure 5A panel 20 is installed on one side of the middle frame shell 10, and a first air outlet 21 is opened on the panel 20, and a second air outlet 11 is provided at the bottom of the middle frame shell 10; the wind shield assembly is movably connected to the panel 20 to switch between a first relative position and a second relative position; wherein, when the wind shield assembly is in the first relative position, the wind shield assembly blocks the first air outlet 21 and exposes the second air outlet 11; when the wind shield assembly is in the second relative position, the wind shield assembly blocks the second air outlet 11 and exposes the first air outlet 21.

[0039] It can be understood that the traditional indoor unit 100 is provided with an air inlet 12 at its top position and an air outlet at its lower position. Furthermore, in order to adjust the direction of the air blown out from the air outlet, an air guide plate is provided at the corresponding position of the air outlet to achieve the effect of adjusting the direction of the air. When the indoor unit 100 is turned off, the air guide plate automatically closes the air outlet.

[0040] However, considering the actual assembly of the air guide plate and the middle frame housing 10, it is unable to effectively avoid the effect of direct blowing of cold air while changing the air outlet direction.

[0041] Although the wind shield 30 is arranged at the middle frame position, and the wind shield 30 is adjusted to move on the middle frame to change its blocking effect on the cold air blown out of the air outlet to the indoor environment, the existence of the wind shield 30 also blocks the air blown by the air conditioner toward a distant location, making it impossible to improve the heat exchange efficiency between the air conditioner and the indoor environment in a short time while ensuring that the cold air is not blown directly, resulting in a reduced user experience.

[0042] In a specific example, the windshield assembly blocks the second air outlet 11 and exposes the first air outlet 21, which is specifically manifested in that the windshield assembly is staggered with the first air outlet 21 so that the first air outlet 21 is not blocked by the windshield assembly, so that the cold air blown out of the first air outlet 21 can directly act on the indoor environment, thereby achieving heat exchange with the indoor environment in front of it. At the same time, the windshield assembly blocking the second air outlet 11 can be understood as the direction of the air blown out by the second air outlet 11 is blocked by it, and the cold air cannot be transported over a long distance, so that the user experiences a windless feeling, thereby achieving the effect of avoiding direct blowing of cold air.

[0043] Furthermore, the indoor unit 100 includes a wall-mounted side 101 and a user side. The wall-mounted side 101 is a side close to the wall. By setting a hanging plate on the wall-mounted side 101, the indoor unit 100 can be smoothly installed on the wall. The user side is arranged opposite to the wall-mounted side 101. Specifically, the panel 20 is arranged on the user side exposed to the user's sight. When the wind shield assembly blocks the second air outlet 11, it is specifically manifested that at least part of the structure of the wind shield assembly extends out of the middle frame shell 10, that is, it is located in the path where the wind guide plate guides the outlet air into the indoor environment, thereby greatly shortening the air supply distance blown out by the second air outlet 11.

[0044] Therefore, in combination with the content of the present technical solution, on the one hand, by setting the first air outlet 21 on the panel 20, heat exchange with the indoor environment is achieved simultaneously through the first air outlet 21 and the second air outlet 11, thereby improving the heat exchange efficiency of the heat exchange between the single second air outlet 11 and the indoor environment; on the other hand, in combination with the difference in position of the first air outlet 21 compared to the second air outlet 11 in the indoor unit 100, specifically, the first air outlet 21 is set at a high position, and its air outlet direction is also blown to the corresponding high position of the indoor environment, so that while it achieves heat exchange with the indoor environment, the cold air blown out from there can form an azimuth misalignment with the user located below it, thereby achieving the effect of avoiding direct blowing of cold air; in addition, in combination with the wind shield component, it can flexibly switch between the first relative position and the second relative position, so that on the basis of effectively avoiding direct blowing of cold air, the heat exchange efficiency with the indoor environment is improved at the same time, thereby improving the user experience.

[0045] Preferably, the windshield assembly is slidably connected to the panel 20; wherein, when the windshield assembly blocks the second air outlet 11, the windshield assembly stops the air from the second air outlet 11 in the direction away from the wall-mounted side 101. Specifically, the technical solution achieves the conversion of the direction of the cold air blown out from the second air outlet 11 to the direction toward the wall-mounted side 101 by adjusting the windshield assembly to the second relative position, or, under the stopping action of the windshield assembly, the direction of the cold air is converted to the downward direction in the vertical direction.

[0046] Therefore, it can be understood that, combined with the actual installation situation of the wall-mounted indoor unit 100, the outlet area of ​​the cold air blown out by the second air outlet 11 is effectively limited to the air outlet range bounded by the wall and the wind shield assembly, thereby weakening the heat exchange efficiency corresponding to the second air outlet 11 and the areas outside the above-mentioned air outlet range, that is, the wind force within the air outlet range is greatly reduced, thereby improving the user experience of users outside the air outlet range.

[0047] Preferably, the panel 20 is provided with a first slide rail at a position corresponding to the windshield assembly; the windshield assembly is provided with a windshield plate 30 that slides with the first slide rail. By making the windshield plate 30 move in the first slide rail, the movement stability and movement efficiency of the windshield plate 30 are effectively improved.

[0048] Preferably, the wind deflector 30 is a flexible member; the trajectory of the first slide rail is adapted to the surface curve of the panel 20 .

[0049] Specifically, by making the trajectory of the first slide rail adapt to the surface curve of the panel 20, on the one hand, the space occupancy rate of the indoor unit 100 is increased during the process of moving the wind shield 30 due to the large deviation between the trajectory of the first slide rail and the surface curve of the panel 20 is reduced; on the other hand, the appearance of the indoor unit 100 changes less during the process of moving the wind shield 30, thereby effectively maintaining the aesthetic appearance of the indoor unit 100.

[0050] Preferably, the panel 20 is provided with an installation opening 22 for accommodating the driving assembly 40 , and the windshield 30 is sandwiched between the first slide rail and the driving assembly 40 ; wherein the driving assembly 40 is driven to drive the windshield 30 to move in the first slide rail.

[0051] Specifically, on the one hand, the wind shield 30 is driven to move between the first relative position and the second relative position by the driving component 40, thereby replacing manual adjustment, improving the adjustment efficiency of the wind shield 30, and improving the user experience; on the other hand, the shielding effect of the wind shield 30 on the driving component 40 effectively avoids the driving component 40 being exposed to the user's line of sight and reducing the aesthetic appearance of the indoor unit 100, and at the same time makes the indoor unit 100 more concise in appearance.

[0052] Preferably, the drive assembly 40 includes a drive motor 41 disposed in the middle frame shell 10 and a transmission gear 42 cooperating with the drive motor 41, and at least part of the structure of the transmission gear 42 extends out of the mounting opening 22; a meshing rack 31 meshing with the transmission gear 42 is provided on one side of the wind shield 30 close to the transmission gear 42.

[0053] Specifically, the windshield 30 moves by meshing the gears and the racks, which improves the stability of movement, effectively avoids slipping during the transmission process, and reduces the noise generated by the windshield 30 during the movement.

[0054] In addition, the windshield 30 is clamped between the transmission gear 42 and the first slide rail. Compared with the pulley transmission method, it effectively avoids the accident that the windshield 30 cannot be effectively transmitted due to the excessive distance between the pulley and the first slide rail during the transmission process.

[0055] Preferably, either the first slide rail or the panel 20 is provided with a plurality of gear engaging parts, and the plurality of gear engaging parts are arranged sequentially along the direction in which the wind shield assembly moves from the first relative position to the second relative position; the other one is provided with a mating engaging part which is engaged with at least one of the plurality of gear engaging parts; wherein, when the wind shield plate 30 is switched between the first relative position and the second relative position, the mating engaging part is engaged with a corresponding one of the plurality of gear engaging parts.

[0056] In a specific example, the gear engaging member can be an arc convex structure, and correspondingly, the matching engaging member is a cylindrical convex structure. Therefore, in the process of adjusting the movement of the wind deflector 30, the cylindrical convex structure is successively matched with different arc convex structures, which prevents the wind deflector 30 from accidentally falling out of the first slide rail during the movement. In particular, when the indoor unit 100 is in the standby state, the cylindrical convex structure is mounted on any one of the multiple arc convex structures, which effectively avoids the wind deflector 30 from falling out of the first slide rail under the action of its gravity. At the same time, the specific state of the wind deflector 30 at this time can be determined according to the gear change sound generated by the cylindrical convex structure hitting the arc convex structure during the adjustment of the wind deflector 30, when the cylindrical convex structure cooperates with different arc convex structures due to overcoming the squeezing force from the first slide rail.

[0057] Among them, the distance formed between the part of the wind shield 30 where the cylindrical protrusion structure is set and the part of the first slide rail where the arc protrusion structure is not set reduces the protrusion height of the arc protrusion structure body, thereby effectively playing an anti-slip effect.

[0058] Preferably, the first sliding rail includes a first rail segment 231 and a second rail segment 232, the first rail segment 231 is arranged at the first end of the panel 20 along its transverse direction, and the second rail segment 232 is arranged at the second end of the panel 20 along its transverse direction; the first rail segment 231 and / or the second rail segment 232 is provided with a pulley set that rolls with the panel 20 on the side away from the transmission gear 42.

[0059] Specifically, by setting up the pulley group, the friction sound caused by the mutual squeezing of the wind shield 30 and the first slide rail in a surface-to-surface manner is effectively avoided, thereby further improving the user experience and ensuring that the wind shield 30 remains relatively quiet during movement.

[0060] Preferably, an air inlet 12 is provided at the top of the middle frame housing 10; the middle frame housing 10 further comprises: a second slide rail, the second slide rail is arranged at the top, and the second slide rail cooperates with the first slide rail to allow the wind shield 30 to slide between the two; wherein, when the wind shield 30 slides to the second slide rail, the wind shield 30 covers the air inlet 12. By covering the air inlet 12 with the wind shield 30, dust is prevented from entering the air inlet 12 when the indoor unit 100 is in the standby state.

[0061] On the other hand, an embodiment of the present invention further provides an air conditioner. Specifically, the air conditioner includes, for example, an indoor unit 100 as in any of the above technical solutions. Correspondingly, this embodiment can achieve the corresponding technical effects in any of the above technical solutions, which will not be described in detail here.

[0062] 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.
