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] The indoor unit of the air conditioner is usually provided with a panel mounting frame, and the panel cover is provided 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 the screws, screws are usually not provided on the front side of the panel, but multiple elastic buckles are provided on the back side of the panel, and the plug-in cards are connected to the card slots on the panel mounting frame.

[0003] However, the reliability of the card connection is poor. When the user touches or pulls the left and right sides of the panel, the panel is easy to fall off the panel mounting frame, causing safety hazards. Especially when the indoor unit of the air conditioner is a vertical cabinet, children are more likely to touch and pull the lower panel of the vertical cabinet, causing the panel to fall off, thereby exposing the internal electrical components and moving components, which is very likely to cause safety accidents.

In this specification, the schematic expressions 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.

[0051] Figure 1 is a schematic partial 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 This embodiment of the present utility model provides an indoor unit of an air conditioner. The indoor unit of the air conditioner includes a vertically arranged panel 100, a panel mounting frame 200, a stopping structure 500, and a locking structure 600.

[0052] The panel 100 covers the front side of the panel mounting frame 200. The stopping structure 500 is fixedly connected to the back surface of the panel 100. The locking structure 600 includes a driving rod 610 and a locking rod 620. The driving rod 610 is vertically arranged and is movably or rotatably connected to the panel mounting frame 200. The locking rod 620 is horizontally slidably connected to the panel mounting frame 200. The driving rod 610 is configured to drive the locking rod 620 to horizontally slide, so that the locking rod 620 and the stopping structure 500 form two states of locking and disengaging.

[0053] The panel 100 covers the front side of the panel mounting frame 200. The panel 100 is generally a thin plate structure and can be made of plastic material, metal material, etc. For example, the panel 100 can be integrally injection molded from plastic material.

[0054] In order to keep the panel beautiful, the front of the panel is usually not provided with holes or rib structures. In the related art, an elastic buckle is provided on the back of the panel, and is installed on the panel mounting frame by means of an elastic plug-in connection. When the user touches or pushes the panel in this connection method, the elastic force threshold of the elastic buckle may be reached, which may easily cause the panel to fall off, thereby exposing the internal electrical components and moving components, which is very likely to cause safety accidents.

[0055] In this embodiment, a vertical driving rod 610 and a horizontally sliding locking rod 620 are provided on the panel installation frame 200, and a blocking structure 500 cooperating with the locking rod 620 is provided on the back of the panel 100. When the panel 100 is in the installation completed state, the locking rod 620 and the blocking structure 500 are in a locked structure, and the locking rod 620 can block the panel 100 from detaching forward from the panel installation frame 200. Since the locking structure between the locking rod 620 and the blocking structure 500 is a physical stop, there is no elastic force threshold. In the locked state, even if the user touches or pushes the panel 100 with force, the panel 100 will not be detached, thereby achieving the effect of improving the reliability and safety of the installation of the panel 100.

[0056] The driving rod 610 can be directly or indirectly fixedly connected to the locking rod 620, or can be connected through a transmission mechanism 630 to drive the locking rod 620 to slide horizontally when moving or rotating. The panel mounting frame 200 can be provided with a horizontally extending slide rail 220 to constrain the locking rod 620 to slide horizontally.

[0057] When installing the panel 100, the driving rod 610 can be driven from the upper side or the lower side of the rear side of the panel 100. The driving rod 610 drives the locking rod 620 to slide horizontally so that the locking rod 620 does not interfere with the blocking structure 500. Then the panel 100 is covered backward and set on the front side of the panel mounting frame 200. Finally, the driving rod 610 is driven in reverse. The driving rod 610 drives the locking rod 620 to slide horizontally in the reverse direction until the locking rod 620 and the blocking structure 500 form a locked state, and the installation is completed.

[0058] The disassembly process of the panel 100 is opposite to the installation process, which will not be described again here.

[0059] In some embodiments of the indoor unit of the present utility model, the driving rod 610 is fixedly connected to the locking rod 620, and the blocking structure 500 is a socket. When the driving rod 610 moves horizontally in one direction, it drives the locking rod 620 to be connected to the socket, thereby achieving a locked state between the locking rod 620 and the blocking structure 500.

[0060] In this embodiment, the jack can be a round hole, a square hole, etc. arranged horizontally. Preferably, the jack is a non-round hole, and the locking rod 620 is matched with the profile of the jack. In this way, the locking rod 620 can restrict the jack in more degrees of freedom. When the locking rod 620 and the jack are in a locked state, it can not only prevent the panel 100 from detaching, but also prevent the panel 100 from rotating and shaking.

[0061] In some embodiments of the indoor unit of the present utility model, as Figure 5 shown, the driving rod 610 is rotatably connected to the panel mounting frame 200 about a vertical axis.

[0062] The locking rod 620 is slidably connected to the panel mounting frame 200 in the left-right direction. The driving rod 610 is drivingly connected to the locking rod 620 through a transmission mechanism 630.

[0063] In this embodiment, the driving rod 610 is rotatably connected to the panel mounting frame 200 about a vertical axis. Compared with a movable connection, the movable space of the driving rod 610 is smaller during a rotational connection, which can reduce the space occupied by the locking structure 600.

[0064] The width of the panel 100 in the left-right direction is usually greater than the depth in the front-back direction. Constraining the locking rod 620 to slide in the left-right direction can make the movable space of the locking rod 620 adapt to the panel 100, thereby reducing the space occupied by the locking structure 600.

[0065] The transmission mechanism 630 can be a link mechanism, a gear mechanism, etc., which converts the rotation of the driving rod 610 about a vertical axis into the sliding of the locking rod 620 in the left-right direction.

[0066] In some embodiments of the indoor unit of the present utility model, as Figure 5 and Figure 8 shown, the transmission mechanism 630 includes a gear 631 and a rack 632. The gear 631 is coaxially and fixedly connected to the driving rod 610, and the rack 632 is fixedly connected to the locking rod 620.

[0067] There are at least two racks 632, at least one of which is meshingly connected to the front side of the gear 631, and at least one of which is meshingly connected to the rear side of the gear 631.

[0068] Both the stop structure 500 and the locking rod 620 are at least two, and both correspond to the rack 632 one by one.

[0069] In this embodiment, the transmission mechanism 630 is a gear mechanism. On the one hand, the gear mechanism has a relatively compact structure and low space occupation. On the other hand, the gear mechanism has high precision, can accurately control the sliding distance of the locking rod 620, and thus accurately control the locking and disengaging states of the locking rod 620 and the stop structure 500.

[0070] Specifically, both the rack 632 and the locking rod 620 extend in the left - right direction. The rack 632 is fixedly connected to one end of the locking rod 620 away from the corresponding stop structure 500. The rack 632 can be adhesively connected, welded, or connected by fasteners to the locking rod 620. The rack 632 and the locking rod 620 can also be integrally formed by injection molding.

[0071] The gear 631 can be meshed with two racks 632. The two racks 632 are parallel to each other. One rack 632 is on the front side of the gear 631, and the other is on the rear side of the gear 631. Thus, when the gear 631 rotates, the two racks 632 slide towards or away from each other. For example, when the gear 631 rotates clockwise, the two racks 632 slide towards each other. At this time, the two locking rods 620 move towards the gear 631. When the movement reaches a preset distance, the locking state with the stop structure 500 is achieved, or the disengaged state from the stop structure 500 is achieved.

[0072] The stop structures 500 can be respectively arranged at the left and right parts of the back surface of the panel 100. Thus, the locking structure 600 can form locks at the left and right parts of the panel 100 simultaneously, improving the firmness of the installation of the panel 100 and preventing the panel 100 from detaching from the panel mounting frame 200.

[0073] In some embodiments of the indoor unit of the present utility model, a plurality of gears 631 can be axially spaced on the driving rod 610. There can be multiple racks 632 corresponding to the gears 631, and there can be multiple locking rods 620 and stop structures 500 corresponding to the racks 632. Exemplarily, when the height of the panel 100 is relatively large, two gears 631 can be axially spaced on the driving rod 610, one at the upper part of the panel mounting frame 200 and the other at the lower part of the panel mounting frame 200. Each gear 631 is matched with two racks 632, two locking rods 620, and two stop structures 500. Thus, when the panel 100 is in the installed state, locks can be formed on both the left and right sides of the upper part and both the left and right sides of the lower part, further improving the firmness of the installation of the panel 100 and preventing the panel 100 from detaching from the panel mounting frame 200.

[0074] In some embodiments of the indoor unit of the present utility model, as Figures 5 - 8 shown, the indoor unit includes a slide rail 220 extending in the left - right direction. The locking rod 620 is slidably connected to the slide rail 220. The left limit structure 221 and the right limit structure 222 are arranged on the slide rail 220.

[0075] The upper end of the panel mounting frame 200 is provided with a fixing hole 240 extending in the vertical direction. The driving rod 610 is coaxially rotatably connected in the fixing hole 240. A threaded hole 640 is coaxially arranged at the upper end of the driving rod 610.

[0076] The panel 100 further includes a horizontally arranged mounting plate 130 that extends backward, and a mounting hole 140 coaxial with the threaded hole 640 is provided on the mounting plate 130.

[0077] In this embodiment, the slide rail 220 can be fixedly connected to or formed on the panel mounting frame 200, and is used to guide and restrict the locking rod 620 to slide in the left - right direction, and can also be used to guide and restrict the rack 632.

[0078] The threaded hole 640 and the mounting hole 140 are detachably fixedly connected through threaded fasteners (such as screws, bolts, etc., not shown in the figure). On the one hand, it can directly restrict the mounting plate 130, thereby restricting the panel 100 to prevent the panel 100 from detaching from the panel mounting frame 200. On the other hand, the threaded fastener is also used to rotate the driving rod 610, and then drive the rack 632 and the locking rod 620 to slide.

[0079] Specifically, when tightening or loosening the mounting threaded fastener, a threaded friction force is formed between the threaded fastener and the threaded hole 640, so that the driving rod 610 rotates in the same direction as the threaded fastener, and then drives the rack 632 and the locking rod 620 to slide.

[0080] The left limit structure 221 and the right limit structure 222 can be baffles, stoppers, etc., and are used to limit the sliding distance of the locking rod 620, and limit the sliding distance to a preset distance. This preset distance can be equal to or slightly larger than the preset distance required for the locking rod 620 to form a locked and disengaged state with the stopping structure 500.

[0081] When the locking rod 620 (or the rack 632) separates from the left limit structure 221 or the right limit structure 222, the threaded friction force between the threaded fastener and the threaded hole 640 will cause the driving rod 610 to rotate in the same direction as the threaded fastener, and then drive the rack 632 and the locking rod 620 to slide. After the locking rod 620 (or the rack 632) slides a preset distance and abuts against the left limit structure 221 or the right limit structure 222, the locking rod 620 will stop sliding. On the one hand, it can prevent the rack 632 from detaching from the gear 631. On the other hand, the rack 632 will block the rotation of the gear 631, so that the threaded fastener can overcome the threaded friction force with the threaded hole 640, and then be tightened and installed in the threaded hole 640, or the threaded fastener can be loosened and removed from the threaded hole 640.

[0082] Exemplarily, when installing the installation panel 100, after the panel 100 is covered on the front side of the panel installation frame 200 backward and the installation hole 140 is aligned with the threaded hole 640, a threaded fastener is passed through the installation hole 140 and the threaded hole 640, and the threaded fastener is rotated in the tightening direction. Under the action of the thread friction force, the driving rod 610 rotates in the same direction as the threaded fastener, thereby driving the rack 632 and the locking rod 620 to slide until the locking rod 620 (or the rack 632) abuts against the left limiting structure 221 or the right limiting structure 222. At this time, the locking rod 620 and the blocking structure 500 form a locked state, and the locking rod 620 stops sliding. Continuing to rotate the threaded fastener in the tightening direction, since the locking rod 620 and the rack 632 stop sliding, the rack 632 blocks the rotation of the gear 631, so that the threaded fastener can overcome the thread friction force with the threaded hole 640, and then be tightened and installed in the threaded hole 640. Through the locking between the locking rod 620 and the blocking structure 500, and the fixed connection between the installation hole 140, the threaded hole 640 and the threaded fastener, the panel 100 can be firmly installed on the panel installation frame 200 to prevent detachment.

[0083] The disassembly process of the panel 100 is opposite to the installation process, and will not be elaborated here.

[0084] In some embodiments of the indoor unit of the present utility model, such as Figure 2 and Figure 8 shown, the indoor unit further includes a decorative panel 300 and an air outlet 400. The decorative panel 300 is detachably and fixedly connected to the upper end of the panel installation frame 200, and is located above the panel 100, the installation hole 140 and the driving rod 610. The air outlet 400 is located above the panel 100. The decorative panel 300 forms the lower end edge of the air outlet 400.

[0085] 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, or can also blow out functional airflows such as fresh air, purification, and humidification.

[0086] The decorative panel 300 can be horizontally or obliquely arranged and inserted backward on the upper side of the panel 100. Forming the lower end edge of the air outlet 400 can, on the one hand, guide the outgoing airflows, and on the other hand, isolate the panel 100 and the air outlet 400 to prevent the outgoing airflows from contacting the panel 100, resulting in too large a temperature difference between the temperature of the panel 100 and the air temperature near the panel 100 and forming condensation on the panel 100. On the other hand, the decorative panel 300 can cover the installation hole 140, the fixing hole 240 and the driving rod 610 to prevent the condensed water at the air outlet 400 from entering the installation hole 140 and the fixing hole 240. Of course, the decorative panel 300 can also cover the threaded fasteners connecting the installation hole 140 and the fixing hole 240 to achieve a beautifying effect.

[0087] In some embodiments of the indoor unit of the present utility model, such asFigures 5 - 7 As shown in the figure, the panel 100 includes a main body plate 110 and two side connection plates 120 fixedly connected to the left and right sides of the main body plate 110. Both side connection plates 120 are located at the rear side of the main body plate 110, and the included angle α between the side connection plate 120 and the main body plate 110 is 95 - 175 degrees.

[0088] At least one stop structure 500 is formed by the convexity on the back surface of each side connection plate 120.

[0089] There are multiple locking rods 620, and they correspond to the stop structures 500 one by one.

[0090] In this embodiment, the panel 100 is integrally U-shaped with an opening facing backward, having good structural strength, especially good bending strength in the vertical direction, which can prevent the panel 100 from deforming.

[0091] The stop structures 500 are all arranged on the back surface of the side connection plates 120 and are located at the rear side of the main body plate 110. In this way, when the stop structures 500 are locked with the corresponding locking rods 620, the left and right sides of the panel 100 can be fixed, improving the firmness of the panel 100 installation.

[0092] In some embodiments of the indoor unit of the present utility model, as Figure 7 shown, the stop structure 500 forms a first stop surface 511 arranged vertically.

[0093] One end of the locking rod 620 close to the corresponding stop structure 500 forms a second stop surface 621 and a third stop surface 622 arranged vertically. The second stop surface 621 stops in front of the first stop surface 511. The third stop surface 622 fits against the back surface of the side connection plate 120.

[0094] In this embodiment, the stop structure 500 forms a lock with the locking rod 620 through the first stop surface 511. Specifically, the second stop surface 621 of the locking rod 620 can be inserted and located in front of the first stop surface 511 during sliding, preventing the first stop surface 511 from moving forward, thereby preventing the panel 100 from detaching from the panel mounting frame 200 forward.

[0095] One end of the locking rod 620 close to the corresponding stop structure 500 also forms a third stop surface 622. When in the locked state, the third stop surface 622 can contact or abut against the back surface of the side connection plate 120, thereby supporting the side connection plate 120 and avoiding or reducing the deformation of the side connection plate 120 due to force. Left and right limit structures 221 and 222 are also formed on the back surfaces of both side connection plates 120. When in the locked state, they stop the sliding of the locking rod 620, thereby stopping the rotation of the rack 632 and the gear 631.
