Description

Technical Field

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

[0002] An indoor unit of an air conditioner is usually provided with a panel mounting frame, and a panel is covered on the front side of the panel mounting frame. In the related art, in order to take into account the aesthetics of the panel and avoid the exposure of screws, screws are usually not provided on the front of the panel, but a plurality of elastic buckles are provided on the back of the panel and are inserted and connected into the card slots on the panel mounting frame.

[0003] However, the reliability of the insertion and connection is poor. When a user touches and presses the left and right sides of the panel, the panel is likely to fall off the panel mounting frame, posing a safety hazard. Especially when the indoor unit of the air conditioner is a floor-standing cabinet type, children are more likely to touch and press the lower panel of the floor-standing cabinet, causing the panel to fall off, and then exposing the internal electrical components and moving components, which is extremely likely to lead to safety accidents. Summary of the Utility Model

[0004] In view of the above problems, the present utility model is proposed to provide an indoor unit of an air conditioner and an air conditioner that can overcome or at least partially solve the above problems, aiming to solve the problem that the existing panel is prone to falling off.

[0005] Specifically, the present utility model provides the following technical solutions:

[0006] An indoor unit of an air conditioner includes a vertically arranged panel and a panel mounting frame.

[0007] The panel includes a body plate, side connecting plates and a first fastening structure. The back surface of the side connecting plate extends backward to form a rigid limiting structure, and the rigid limiting structure has a limiting block protruding in a direction away from the body plate.

[0009] The panel mounting frame includes a second fastening structure and rigid blocking plates corresponding to the limiting blocks one by one. The first fastening structure is detachably and fixedly connected to the second fastening structure.

[0010] Each rigid blocking plate is located in front of the corresponding limiting block. In the left-right direction, the distance between the rigid blocking plate and the second fastening structure is less than the distance between the corresponding limiting block and the second fastening structure.

[0011] Optionally, the rigid limit structure includes a rigid support protruding backward from the back surface of the side connection plate. The limit block is fixedly connected to a side of the rigid support away from the first fastening structure.

[0012] Limit holes corresponding to the rigid limit structure one by one are provided on the panel mounting frame, and a rigid stop plate is formed on a side wall of the limit hole away from the second fastening structure.

[0013] Optionally, the panel mounting frame includes two fixing columns extending vertically and spaced apart in the left-right direction. The fixing column includes a front side wall and a side wall, and the side wall is fixedly connected to a side of the front side wall away from the second fastening structure.

[0014] The limit hole is provided on the front side wall.

[0015] Optionally, the panel further includes a plurality of limit ribs protruding backward from the back surface of the side connection plate.

[0016] All the limit ribs are on a side of the side wall away from the first fastening structure, and the rear ends of the limit ribs are all behind the front side wall. The distance between the limit rib and the side wall is 1-2 times the height of the limit block in the left-right direction.

[0017] Optionally, the side connection plate is behind the body plate, and the included angle between the side connection plate and the body plate is 95-175 degrees.

[0018] One end of the side connection plate away from the body plate extends away from the body plate to form a handle, and at least part of the handle is outside the panel mounting frame in the left-right direction.

[0019] Optionally, the first fastening structure is at the upper end and / or the lower end of the back surface of the body plate. The first fastening structure includes a mounting post protruding backward from the back surface of the body plate and a mounting hole provided on the mounting post and arranged vertically.

[0020] The second fastening structure includes a fixing hole provided on the panel mounting frame and coaxial with the mounting hole.

[0021] Optionally, the first fastening structure is not at the lower end of the back surface of the body plate.

[0022] A downwardly concave card slot is fixedly connected to the lower end of the back surface of the body plate. An upwardly protruding card post corresponding to the card slot is provided on the panel mounting frame.

[0023] Optionally, the indoor unit further includes a decorative plate and an air outlet.

[0024] The decorative panel is detachably and fixedly connected to the upper side of the panel, and covers the upper sides of the mounting hole and the fixing hole.

When the first fastening structure and the second fastening structure are in a fixedly connected state, they will form a constraint on the main body plate, preventing the main body plate from disengaging from the panel mounting frame forward and preventing the middle part of the main body plate from bulging and deforming forward. When a user touches and presses the side connecting plates on the left and right sides of the panel, since the middle part of the main body plate is constrained, the left and right sides of the main body plate are recessed forward along with the two side connecting plates, so that the limiting blocks on the back surfaces of the two side connecting plates both move outward and are blocked by the corresponding rigid stop plates. That is to say, the rigid stop plate can prevent the side connecting plates from disengaging from the panel mounting frame forward. The combined action of the second fastening structure and the rigid stop plate solves the problem that the existing panel is prone to falling off, and achieves the effects of improving the reliability and safety of the panel installation.

In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0053] Figure 1 is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present utility model, as Figure 1 shown, and with reference to Figures 2 - 15 . The embodiment of the present utility model provides an indoor unit of an air conditioner, including a vertically arranged panel 100 and a panel mounting frame 200.

[0054] The panel 100 includes a main body plate 110, side connection plates 120, and a first fastening structure 140. The back surface of the side connection plate 120 extends backward to form a rigid limiting structure 130, and the rigid limiting structure 130 has a limiting block 132 protruding in a direction away from the main body plate 110. There are two side connection plates 120, which are respectively fixedly connected to the left and right sides of the main body plate 110.

[0055] The first fastening structure 140 is located on the back surface of the main body plate 110. In the left - right direction, the first fastening structure 140 and any one of the rigid limiting structures 130 are both arranged at intervals.

[0056] The panel mounting frame 200 includes a second fastening structure 210 and rigid stop plates 220 corresponding one - to - one to the limiting blocks 132. The first fastening structure 140 is detachably and fixedly connected to the second fastening structure 210.

[0057] Each rigid stop plate 220 is located on the front side of the corresponding limit block 132. In the left-right direction, the distance L1 between the rigid stop plate 220 and the second fastening structure 210 is less than the distance L2 between the corresponding limit block 132 and the second fastening structure 210.

[0058] In this embodiment, the body plate 110 covers the front side of the panel mounting frame 200. The body plate 110 is usually a thin plate structure and can be made of plastic or metal. The body plate 110 has a certain deformation ability. When the panel 100 is only installed on the panel mounting frame 200 through elastic buckles, when the user touches or pulls the side connection plates 120 on both sides of the body plate 110, the body plate 110 deforms under force, causing a gap between the side connection plates 120 and the panel mounting frame 200. When the force exceeds the preset value, the side connection plates 120 will disengage from the panel mounting frame 200.

[0059] To solve the above problems, this embodiment provides a detachable fixed connection between the first fastening structure 140 and the second fastening structure 210, which is used to form a restraint on the body plate 110 to prevent the body plate 110 from deforming. Specifically, at least prevent the body plate 110 from bulging forward. The first fastening structure 140 and the second fastening structure 210 can be fastener assemblies, such as screw-hole assemblies, pin-hole assemblies. The first fastening structure 140 and the second fastening structure 210 can also be locking assemblies. When locked, the first fastening structure 140 and the second fastening structure 210 are fixedly connected. When unlocked, the first fastening structure 140 and the second fastening structure 210 are disengaged.

[0060] At the same time, this embodiment also provides a rigid limit structure 130 and a rigid stop plate 220 connected by a buckle. The rigid limit structure 130 is firmly connected to the back of the side connection plate 120, and the rigid limit structure 130 is not easily deformed relative to the side connection plate 120. The rigid stop plate 220 is firmly connected to the skeleton of the panel mounting frame 200, and the rigid stop plate 220 is not easily deformed relative to the panel mounting frame 200.

[0061] Please refer to the following Figures 3 - 4 , Figures 3 - 4 , which shows two states of the rigid limit structure 130 and the rigid stop plate 220 of an embodiment.

[0062] As Figure 3 shown, Figure 3 the lower middle is the front. When the first fastening structure 140 and the second fastening structure 210 are in a fixedly connected state, the body plate 110 is restricted to prevent the body plate 110 from detaching from the panel mounting frame 200 forward and prevent the middle part of the body plate 110 from bulging forward. At this time, the limit block 132 is located behind the rigid stop plate 220.

[0063] When the user touches and presses the side connection plates 120 on the left and right sides of the panel 100, for example, when pressing the outer ends of the side connection plates 120 in the left and right directions outward, since the middle part of the main body plate 110 is restricted, the left and right sides of the main body plate 110 are recessed forward along with the two side connection plates 120, causing the two side connection plates 120 to rotate forward. Further, the limit catch blocks 132 on the back surfaces of the two side connection plates 120 both move outward and are blocked by the corresponding rigid stop plates 220. That is to say, the rigid stop plates 220 can prevent the side connection plates 120 from detaching from the panel mounting frame 200 forward. The second fastening structure 210 and the rigid stop plates 220 act together to solve the problem that the existing panel 100 is prone to falling off, achieving the effects of improving the reliability and safety of the installation of the panel 100.

[0064] As Figure 4 shown, Figure 4 the arrows in the figure indicate the deformation directions of each area of the panel 100. In the case where the first fastening structure 140 and the second fastening structure 210 are in a separated state, the main body plate 110 is not restricted, the main body plate 110 can detach from the panel mounting frame 200 forward, and the main body plate 110 can bulge forward and deform. At this time, when the user squeezes from the outer ends of the side connection plates 120 towards the middle, or pulls the main body plate 110 forward, the main body plate 110 can be made to bulge forward and deform. That is to say, the side connection plates 120 on both sides of the main body plate 110 are rotated backward, and further, the limit catch blocks 132 on the back surfaces of the two side connection plates 120 both move inward. After L2 is less than or equal to L1, the limit catch blocks 132 can be smoothly moved out of the rigid stop plates 220 from back to front, or the limit catch blocks 132 can be smoothly moved to the rear side of the rigid stop plates 220 from front to back.

[0065] When installing the panel 100, apply force to the main body plate 110 to make the main body plate 110 bulge forward and deform. After L2 is less than or equal to L1, the limit catch blocks 132 can be smoothly inserted from front to back behind the rigid stop plates 220. Stop applying force, the main body plate 110 returns to its original state, and finally the first fastening structure 140 and the second fastening structure 210 are fixedly connected, thus realizing the installation of the panel 100.

[0066] When disassembling the panel 100, first disassemble the first fastening structure 140 and the second fastening structure 210, and then apply force to the main body plate 110 to make the main body plate 110 bulge forward and deform. After L2 is less than or equal to L1, the limit catch blocks 132 can be smoothly moved out of the rigid stop plates 220 from back to front, thus realizing the disassembly of the panel 100.

[0067] It should be understood that one or more rigid limiting structures 130 can be provided on each side connection plate 120. For example, two rigid limiting structures 130 are arranged at intervals along the vertical direction on each side connection plate 120, and are respectively located at the upper and lower parts of the side connection plate 120 to improve the reliability of the fixed connection between the panel 100 and the panel mounting frame 200.

[0068] In some embodiments of the indoor unit of the present utility model, as Figure 2 shown, the rigid limiting structure 130 includes a rigid support 134 extending backward from the back surface of the side connection plate 120. The limiting block 132 is fixedly connected to one side of the rigid support 134 away from the first fastening structure 140.

[0069] Limiting holes 230 corresponding to the rigid limiting structures 130 one by one are provided on the panel mounting frame 200, and a rigid stop plate 220 is formed on the hole wall on one side of the limiting hole 230 away from the second fastening structure 210.

[0070] In this embodiment, the rigid support 134 is used to firmly support the limiting block 132 to prevent the limiting block 132 from deforming relative to the side connection plate 120.

[0071] The limiting holes 230 can be round holes, square holes, etc., which are not limited here.

[0072] When the front ends of the limiting block 132 and the rigid support 134 are inserted into the limiting hole 230, the peripheral hole walls of the limiting hole 230 can also form a constraint on the rigid limiting structure 130. During installation, the peripheral hole walls of the limiting hole 230 form a guide for the rigid limiting structure 130, facilitating the quick insertion of the limiting block 132 into the limiting hole 230.

[0073] In some embodiments of the indoor unit of the present utility model, as Figure 2 and Figure 5 shown, the panel mounting frame 200 includes two fixing columns 240 extending along the vertical direction and arranged at intervals in the left - right direction. The fixing column 240 includes a front side wall 242 and a side wall 244, and the side wall 244 is fixedly connected to one side of the front side wall 242 away from the second fastening structure 210.

[0074] The limiting holes 230 are provided on the front side wall 242.

[0075] In this embodiment, the fixing column 240 can be a sheet metal part for forming the skeleton of the indoor unit. The side connection plate 120 is installed on the fixing column 240, and the fixing column 240 can provide stable and firm support for the panel 100.

[0076] In some embodiments of the indoor unit of the present utility model, as Figure 2 shown, the panel 100 further includes a plurality of limiting ribs 150 protruding backward from the back surface of the side connection plate 120.

[0077] The limiting ribs 150 are all on the side of the side side wall 244 away from the first fastening structure 140, and the rear ends of the limiting ribs 150 are all on the rear side of the front side wall 242. The distance L4 between the limiting rib 150 and the side side wall 244 is 1-2 times the height L3 of the limiting block 132 in the left-right direction.

[0078] In this embodiment, the side side wall 244 and the limiting rib 150 are in clearance fit to limit the limiting rib 150, thereby limiting the side connecting plate 120.

[0079] Specifically, when installing and disassembling the panel 100, on the one hand, the side side wall 244 can guide the limiting rib 150, facilitating the quick insertion of the limiting block 132 into the limiting hole 230 or the quick extraction of the limiting block 132 from the limiting hole 230. On the other hand, when the deformation amount of the main body plate 110 meets the requirements, the limiting rib 150 will abut against the side side wall 244, which can prevent the main body plate 110 from deforming excessively and avoid damage to the panel 100 caused by excessive force application.

[0080] In some embodiments of the indoor unit of the present utility model, such as Figure 1 、 Figure 2 and Figure 6 shown, the side connecting plate 120 is on the rear side of the main body plate 110, and the included angle α between the side connecting plate 120 and the main body plate 110 is 95-175 degrees.

[0081] One end of the side connecting plate 120 away from the main body plate 110 extends away from the main body plate 110 to form a handle 160, and at least part of the handle 160 is outside the panel mounting frame 200 in the left-right direction.

[0082] In this embodiment, the panel 100 is integrally U-shaped with an opening facing backward. On the one hand, it has good structural strength, especially good bending strength in the vertical direction, which can prevent the panel 100 from deforming. On the other hand, during installation and disassembly, it can be conveniently squeezed inward from the outer end of the side connecting plate 120 to cause the main body plate 110 to bulge forward, so that L2 is reduced to be less than or equal to L1, which can improve the efficiency of installation and disassembly.

[0083] In this embodiment, the handle 160 can provide a force application point, facilitating the user to push the handle 160 backward during installation so that the limiting block 132 is inserted behind the rigid limiting plate. During disassembly, the handle 160 can be pulled forward to make the panel 100 move forward and smoothly disengage from the panel mounting frame 200.

[0084] In some embodiments of the indoor unit of the present utility model, such as Figures 5 - 9As shown, the first fastening structure 140 is located at the upper end and / or the lower end of the back surface of the main body plate 110. The first fastening structure 140 includes a mounting post 142 extending backward from the back surface of the main body plate 110 and a mounting hole 144 provided on the mounting post 142 and arranged vertically.

[0085] The second fastening structure 210 includes a fixing hole 211 provided on the panel mounting frame 200 and coaxial with the mounting hole 144.

[0086] In this embodiment, the first fastening structure 140 and the second fastening structure 210 are detachably fixedly connected by fasteners. Specifically, the first fastening structure 140 is the vertically arranged mounting hole 144, and the second fastening structure 210 is the vertically arranged fixing hole 211. The mounting hole 144 and the fixing hole 211 can be detachably fixedly connected by screws, pin shafts, etc., and limit the main body plate 110 in the front-rear direction. This structure is simple, reliable, easy to process, and has a low cost.

[0087] Since the mounting hole 144 is vertically arranged and located on the back surface of the main body plate 110, there will be no hole structure on the front surface of the panel 100, that is, it will not affect the appearance of the panel 100.

[0088] In some embodiments of the indoor unit of the present utility model, such as Figures 10 - 13 As shown, the first fastening structure 140 is not located at the lower end of the back surface of the main body plate 110.

[0089] A downwardly concave card slot 182 is fixedly connected to the lower end of the back surface of the main body plate 110. An upwardly protruding card post 282 corresponding to the card slot 182 is provided on the panel mounting frame 200.

[0090] In this embodiment, the first fastening structure 140 is located at the upper end of the panel 100 and limits the upper part of the panel 100. The lower end of the panel 100 is limited by the card slot 182 and the card post 282.

[0091] During installation, first tilt the upper end of the main body plate 110 forward, put the card slot 182 at the lower end of the main body plate 110 on the card post 282 of the panel mounting frame 200, then take the card slot 182 as the rotation axis, push the upper end of the panel 100 to rotate backward, so that the limit card block 132 is inserted behind the rigid limit plate, and finally fixedly connect the first fastening structure 140 and the second fastening structure 210.

[0092] A plurality of card slots 182 can be arranged at intervals in the left-right direction at the lower end of the main body plate 110, and card posts 282 corresponding to the plurality of card slots 182 are provided on the panel mounting frame 200 to further limit the lower end of the panel 100 and prevent the panel 100 from detaching from the panel mounting frame 200.

[0093] In some embodiments of the indoor unit of the present utility model, such asFigure 1 and Figure 5 As shown in Figure 5 , the indoor unit further includes a decorative panel 300 and an air outlet 400.

[0094] The decorative panel 300 is detachably and fixedly connected to the upper side of the panel 100, and covers the upper sides of the mounting holes 144 and the fixing holes 211.

[0095] The air outlet 400 is located on the upper side of the panel 100. The decorative panel 300 forms the lower end edge of the air outlet 400.

[0096] In this embodiment, the air outlet 400 can be located in the middle of the indoor unit, blowing out temperature-adjusting airflows such as refrigeration and heating, and can also blow out functional airflows such as fresh air, purification, and humidification.

[0097] The decorative panel 300 can be set horizontally or obliquely, and is inserted backward on the upper side of the panel 100. By forming the lower end edge of the air outlet 400, on the one hand, it can guide the outgoing airflows, and on the other hand, it can isolate the panel 100 and the air outlet 400, preventing the outgoing airflows from contacting the panel 100 and causing too large a temperature difference between the temperature of the panel 100 and the air temperature near the panel 100, resulting in condensation on the panel 100.
