Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning structures, and in particular to an air-conditioning cabinet. Background Art

[0002] In order to facilitate the cleaning of the air conditioner cabinet, the air outlet frame can generally be removed from the front panel lining.

[0003] In the prior art, the air outlet frame is generally slidable upward relative to the front panel lining to facilitate its removal. However, since the air outlet frame can slide relative to the front panel lining, it is prone to shaking during product transportation, which can cause the air outlet frame to collide with other components and even damage the air outlet frame and other components. Summary of the Invention

[0004] The problem solved by the present invention is how to improve the problem that the air outlet frame collides with other components and causes damage.

[0005] In order to solve the above problems, the present invention provides an air-conditioning cabinet unit, which can effectively improve the above-mentioned technical problems.

[0006] The present invention can be implemented like this:

[0007] An embodiment of the present invention provides an air-conditioning cabinet, which includes a front panel lining, the top wall of which is provided with a first connecting portion; an air outlet frame slidably matched with the front panel lining, the top wall of which is provided with a second connecting portion; and a knock-off structure, the two ends of the knock-off structure being respectively connected to the first connecting portion and the second connecting portion to limit the air outlet frame from sliding relative to the front panel lining.

[0008] By providing a knock-off structure that is simultaneously connected to a first connection portion provided on the top wall of the front panel lining plate and a second connection portion provided on the top wall of the air outlet frame, the sliding movement of the air outlet frame relative to the front panel lining plate can be restricted, thereby reducing the possibility of collision with other components caused by the air outlet frame sliding relative to the front panel lining plate during transportation, thereby reducing the possibility of damage to the air outlet frame and other components. In addition, after transportation is completed, the restrictive effect of the knock-off structure can be eliminated by disassembling or destroying the knock-off structure, so that the air outlet frame can slide relative to the front panel lining plate, facilitating subsequent disassembly and cleaning of the air outlet frame.

[0009] Optionally, the knock-off structure has a breakable portion, and a connection point between the knock-off structure and the first connection portion and a connection point between the knock-off structure and the second connection portion are respectively located on both sides of the breakable portion.

[0010] Since the knock-off structure is provided with a breakable portion, and the connection between the knock-off structure and the first connecting portion and the connection between the knock-off structure and the second connecting portion are respectively located on both sides of the breakable portion, after the breakable portion is destroyed and the knock-off structure is broken into two parts, the first connecting portion and the second connecting portion are respectively connected to the two parts. At this time, the air outlet frame can slide relative to the front panel lining under the action of external force.

[0011] Optionally, a through hole is provided at the breakable portion, and the through hole is provided through the thickness direction of the knockable structure.

[0012] A through hole is provided on the knock-off structure to form an easily breakable portion, and the through hole is arranged to penetrate along the thickness direction of the knock-off structure. The knock-off structure has a simple structure and is easy to produce.

[0013] Optionally, the fragile portion has a first wall and a second wall that define the through hole, and the first wall and the second wall are spaced apart in the direction from the first connecting portion to the second connecting portion; the fragile portion also includes a step portion arranged in the through hole, and both ends of the step portion are respectively connected to the first wall and the second wall.

[0014] A step is provided within the through-hole, extending from the first connecting portion to the second connecting portion. This strengthens the breakable portion in that direction, ensuring the knock-off structure effectively restricts relative movement between the air outlet frame and the front panel lining. The step is also relatively thin, making it easier to break.

[0015] Optionally, the first connecting portion is detachably connected to the knock-off structure.

[0016] The first connection part is detachably connected to the knock-off structure, which facilitates the assembly of the knock-off structure and the front panel lining. After the transportation is completed, the first connection part and the knock-off structure can be disassembled to achieve the separation of the first connection part and the knock-off structure, thereby avoiding the knock-off structure affecting the relative movement of the air outlet frame and the front panel lining after the transportation is completed.

[0017] Optionally, the first connecting portion includes a plate body arranged on the top wall of the front panel lining, and a snap-in hole is provided on the plate body; one end of the knock-off structure has a first hook, and the first hook is snap-connected with the snap-in hole.

[0018] The first connecting portion and the knock-off structure are detachably connected by means of a hook connection. By adopting the hook connection method, no tools are required during the disassembly and assembly process, making the disassembly and assembly more convenient.

[0019] Optionally, the second connecting portion is detachably connected to the knock-off structure.

[0020] The second connection part is detachably connected to the knock-off structure, which facilitates the assembly of the knock-off structure and the air outlet frame. After the transportation is completed, the second connection part and the knock-off structure can be disassembled to achieve the separation of the second connection part and the knock-off structure, thereby avoiding the knock-off structure affecting the relative movement of the air outlet frame and the front panel lining after the transportation is completed.

[0021] Optionally, the knock-off structure has a second hook, and the upper end of the second connecting portion has a hooking protrusion, and the second hook is engaged with the hooking protrusion.

[0022] The second connecting portion and the knock-off structure are detachably connected by means of a hook connection. By adopting the hook connection method, no tools are required during the disassembly and assembly process, making the disassembly and assembly more convenient.

[0023] Optionally, the knock-off structure is further provided with a stop protrusion, which is located on the side of the second hook close to the second connecting part, and the stop protrusion is used to abut against the side wall of the second connecting part to prevent the hooking protrusion from detaching from the second hook.

[0024] Since the knock-off structure and the second connecting part are detachably connected by the hook, a resisting protrusion is provided on the side of the second hook close to the second connecting part, so that the resisting protrusion abuts against the side wall of the second connecting part, the second connecting part can be limited to prevent the second connecting part from moving away from the second hook, so as to avoid the hooking protrusion on the second connecting part from being separated from the second hook, thereby ensuring the connection reliability of the knock-off structure and the second connecting part, and further helping to ensure the reliability of the sliding restriction of the knock-off structure between the air outlet frame and the front panel lining.

[0025] Optionally, the lower end of the retaining protrusion has a guide surface, and the guide surface is arranged toward the second hook, for guiding the upper end of the second connecting portion to enter the space between the retaining protrusion and the second hook.

[0026] By setting a guide surface in the direction of the second hook in the resisting area to guide the hooking protrusion of the second connecting part into the space between the resisting protrusion and the second hook, the connection between the knock-off structure and the second connecting part is more convenient and the use effect is good.

[0027] An embodiment of the present invention further provides an air conditioner, comprising a cabinet air conditioner. The cabinet air conditioner comprises a front panel lining, a top wall of the front panel lining being provided with a first connecting portion; an air outlet frame slidably engaged with the front panel lining, a top wall of the air outlet frame being provided with a second connecting portion; and a knock-off structure, two ends of the knock-off structure being respectively connected to the first connecting portion and the second connecting portion to restrict the air outlet frame from sliding relative to the front panel lining.

[0028] Since the air conditioner includes an air conditioning cabinet, it can also improve the problem of the air outlet frame sliding relative to the front panel lining during transportation, causing the air outlet frame to collide with other components, and even causing damage to the air outlet frame and other components.

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] Figure 1 This is a partial structural diagram of the air conditioning cabinet 100 provided in this embodiment. Figure 2 for Figure 1 The enlarged schematic diagram of the local structure at Ⅱ in the middle. Please refer to Figure 1 and Figure 2 , this embodiment provides an air conditioning cabinet 100, and accordingly, provides an air conditioner.

[0039] The air conditioner includes an air conditioning cabinet 100 and an air conditioning outdoor unit. When in use, the air conditioning cabinet 100 is placed indoors and the air conditioning outdoor unit is set outdoors. Through the joint action of the air conditioning outdoor unit and the air conditioning cabinet 100, heat exchange between indoor and outdoor is achieved.

[0040] The air conditioning cabinet 100 includes a front panel lining 110, an air outlet frame 120 and a knock-down structure 130. The air outlet frame 120 is slidably matched with the front panel lining 110, and the top wall of the front panel lining 110 is provided with a first connecting portion 111, and the top wall of the air outlet frame 120 is provided with a second connecting portion 121. The two ends of the knock-down structure 130 are respectively connected to the first connecting portion 111 and the second connecting portion 121 to limit the sliding of the air outlet frame 120 relative to the front panel lining 110. In this way, during transportation, the movement of the air outlet frame 120 relative to the front panel lining 110 is limited by the knock-down structure 130, reducing the collision between the air outlet frame 120 and other components, thereby reducing the possibility of damage to the air outlet frame 120 and other components. In addition, after the transportation is completed, the knock-off structure 130 can be destroyed or disassembled to separate the knock-off structure 130 from the first connecting part 111 and the second connecting part 121, so that the restrictive effect of the knock-off structure 130 disappears. In this way, the air outlet frame 120 can slide relative to the front panel lining 110, making it convenient for subsequent users to disassemble the air outlet frame 120 for cleaning.

[0041] The following further describes the air conditioning cabinet 100 provided in this embodiment:

[0042] Figure 3 This is a schematic cross-sectional view of the knock-down structure 130 of the air-conditioning cabinet 100 provided in this embodiment. Figure 4 This is a structural diagram of the knock-down structure 130 in the air-conditioning cabinet 100 provided in this embodiment at a first viewing angle. Figure 5 This is a schematic diagram of the structure of the knock-down structure 130 in the air-conditioning cabinet 100 provided in this embodiment at a second viewing angle. Figure 1-Figure 5 In this embodiment, the first connection part 111 is detachably connected to the knock-off structure 130, so that the first connection part 111 and the knock-off structure 130 can be disconnected or connected by disassembling and assembling the first connection part 111 and the knock-off structure 130, which is convenient for assembly and use.

[0043] Optionally, the first connecting portion 111 includes a plate body 112 disposed on the top wall of the front panel liner 110, and a snap-in hole 113 is defined in the plate body 112. One end of the knock-off structure 130 includes a first hook 132, which snaps into engagement with the snap-in hole 113. It will be appreciated that in other embodiments, a screw connection or other method may be employed to achieve a detachable connection between the knock-off structure 130 and the first connecting portion 111.

[0044] Specifically, the engaging hole 113 is provided vertically through the plate body 112. The knock-off structure 130 includes a generally elongated connecting plate 131, a first hook 132 disposed at the lower side of one end of the connecting plate 131 in the longitudinal direction, and the first hook 132 includes a first hooking protrusion 133. The first hooking protrusion 133 is located along the longitudinal direction of the connecting plate 131, on the side of the first hook 132 facing away from the connecting plate 131. During installation, the first hook 132 is inserted from the top downward into the engaging hole 113, and the upper end surface of the first hooking protrusion 133 abuts against the lower end surface of the plate body 112, thereby achieving the engaging connection between the first connecting portion 111 and the knock-off structure 130.

[0045] Optionally, in order to facilitate the first hook 132 to be locked into the locking hole 113, a first inclined surface is provided on the first hook protrusion 133, so that when the first hook 132 moves downward into the locking hole 113, the first inclined surface can interfere with the plate body 112, causing the first hook 132 to produce a certain elastic deformation, thereby allowing the first hook protrusion 133 to smoothly enter the locking hole 113, and after extending into the lower side of the locking hole 113, it interferes with the lower end surface of the plate body 112.

[0046] In this embodiment, the second connection part 121 is detachably connected to the knock-off structure 130, so that the second connection part 121 and the knock-off structure 130 can be disconnected or connected by disassembling and assembling the second connection part 121 and the knock-off structure 130, which is convenient for assembly and use.

[0047] It should be noted that in this embodiment, the first connection part 111 and the second connection part 121 are both detachably connected to the knock-off structure 130. It can be understood that in some other embodiments, the connection method between the first connection part 111 and the second connection part 121 and the knock-off structure 130 can also be specifically set according to needs. For example, only one of the first connection part 111 and the second connection part 121 is set to be detachably connected to the knock-off structure 130.

[0048] Optionally, the knock-off structure 130 has a second hook 134, and the upper end of the second connecting portion 121 is provided with a hooking protrusion, which is the third hooking protrusion 122, and the second hook 134 is engaged with the third hooking protrusion 122. It is understood that in other embodiments, the knock-off structure 130 and the second connecting portion 121 can also be detachably connected by means such as screw connection.

[0049] Specifically, the second hook 134 is disposed on the lower side of the connecting plate 131, away from one end of the first hook 132 in the longitudinal direction. The second hook 134 has a second hooking protrusion 135. The second hooking protrusion 135 is located on the side of the second hook 134 facing away from the first hook 132, that is, the first hooking protrusion 133 and the second hooking protrusion 135 are arranged in opposite directions. The second connecting portion 121 includes a vertically arranged support arm, and the third hooking protrusion 122 is disposed on the upper side of the support arm, that is, the second connecting portion 121 as a whole is in the shape of an upwardly facing hook. The mutual interference and limiting of the second hooking protrusion 135 and the third hooking protrusion 122 achieve the connection between the knock-off structure 130 and the second connecting portion 121.

[0050] Optionally, a second inclined surface is provided on the second hooking protrusion 135, and a third inclined surface is provided on the third hooking protrusion 122. When the second hooking protrusion 135 moves downward relative to the third hooking protrusion 122, so that the third hooking protrusion 122 is located on the upper side of the second hooking protrusion 135, the second inclined surface and the third inclined surface interfere with each other during the process of the second hook 134 being engaged with the second connecting part 121, and the installation is smoother.

[0051] Please continue to refer to Figure 1-Figure 5 Furthermore, the knock-off structure 130 is further provided with a stop protrusion 136. The stop protrusion 136 is located on the side of the second hook 134 close to the second connecting portion 121. That is, the second hooking protrusion 135 of the second hook 134 is arranged toward the stop protrusion 136. In this way, the upper end of the second connecting portion 121 is located between the second hook 134 and the stop protrusion 136. The stop protrusion 136 is used to abut against the side wall of the second connecting portion 121 to prevent the third hooking protrusion 122 from disengaging from the second hook 134.

[0052] Specifically, the retaining protrusion 136 is disposed on the underside of the connecting plate 131 and is located on the side of the second hook 134 away from the first hook 132. Thus, the space between the second hook 134 and the retaining protrusion 136 serves as a mounting space for the upper end of the second connecting portion 121. After the second hook 134 is hooked and secured to the upper end of the second connecting portion 121, the retaining protrusion 136 limits the second connecting portion 121, preventing the second hook 134 from detaching from the second connecting portion 121, thereby providing a more secure connection.

[0053] Furthermore, a guide surface 137 is provided at the lower end of the retaining protrusion 136. The guide surface 137 is disposed toward the second hook 134 to guide the upper end of the second connecting portion 121 into the space between the retaining protrusion 136 and the second hook 134. In this embodiment, the guide surface 137 is an inclined surface, disposed from bottom to top toward the second hook 134, thereby increasing the size of the lower opening of the installation space and facilitating the connection between the second connecting portion 121 and the second hook 134. It will be appreciated that in other embodiments, the guide surface 137 may also be a curved surface, for example.

[0054] Furthermore, the connecting plate 131 includes a first strip portion 1311 and a second strip portion 1312, which are connected in sequence along its length. The first strip portion 1311 is smaller in the width direction of the connecting plate 131 than the second strip portion 1312. A first hook 132 and a second hook 134 are connected to both ends of the first strip portion 1311. Specifically, the first hook 132 is located at the end of the first strip portion 1311 away from the second strip portion 1312, and the second hook 134 is located at the junction of the first strip portion 1311 and the second strip portion 1312. A blocking protrusion is provided at the end of the second strip portion 1312 away from the first strip portion 1311.

[0055] Figure 6 This is a schematic cross-sectional view of the knock-off structure 130 at the breakable portion 138 of the air conditioning cabinet 100 provided in this embodiment. Specifically, Figure 6 The cross-sectional view shown is obtained by cutting along the width direction of the connecting plate 131. Figures 1-6 In this embodiment, the knock-off structure 130 has a breakable portion 138 , and the connection between the knock-off structure 130 and the first connection portion 111 and the connection between the knock-off structure 130 and the second connection portion 121 are respectively located on both sides of the breakable portion 138 .

[0056] The connection point between the knock-off structure 130 and the first connecting part 111 is the first hook 132, and the connection point between the knock-off structure 130 and the second connecting part 121 is the second hook 134. The easily breakable part 138 is part of the connecting plate 131, so the easily breakable part 138 is the part of the connecting plate 131 located between the first hook 132 and the second hook 134, that is, the easily breakable part 138 is arranged at the first strip part 1311.

[0057] Thus, when the easily breakable portion 138 is destroyed, for example by shearing, so that the connecting plate 131 of the knock-off structure 130 breaks from the easily breakable portion 138, the first hook 132 and the second hook 134 are respectively located on the two separated parts of the connecting plate 131, and the knock-off structure 130 no longer restricts the relative movement between the air outlet frame 120 and the front panel lining 110. At this time, the air outlet frame 120 can be operated to slide upward relative to the front panel lining 110 to be removed. At the same time, by providing the easily breakable portion 138, the first connecting portion 111 and the second connecting portion 121 can be more conveniently and quickly separated after transportation is completed by destroying the easily breakable portion 138.

[0058] Specifically, the portion of the connecting plate 131 between the first hook 132 and the second hook 134 is provided with a through hole 139, so that the through hole 139 forms the breakable portion 138. In other words, it can also be considered that the breakable portion 138 is provided with a through hole 139. At the same time, the through hole 139 is formed along the thickness direction of the knockable structure 130 (i.e., Figure 6 and Figure 3 The connecting plate 131 is provided with a plurality of connecting members (in the vertical direction shown). It is understood that in other embodiments, the fragile portion 138 can be formed on the connecting plate 131 in other ways as needed, for example, the fragile portion 138 can be made of a material that is more brittle than the material of other parts of the connecting plate 131.

[0059] Furthermore, the fragile portion 138 has a first wall and a second wall defining a through hole 139, the first wall and the second wall being spaced apart from each other along the direction from the first connecting portion 111 to the second connecting portion 121. The fragile portion 138 also includes a step portion 1393 disposed within the through hole 139, with both ends of the step portion 1393 connected to the first wall and the second wall, respectively.

[0060] Specifically, through hole 139 includes a large hole section 1391 and a small hole section 1392 that are interconnected, and are defined between a first wall and a second wall provided along the length of connecting plate 131. Large hole section 1391 has a square cross-section, and small hole section 1392 has a square cross-section. Furthermore, the cross-section of small hole section 1392 in the width direction of connecting plate 131 is smaller than the cross-section of large hole section 1391 in the width direction of connecting plate 131.

[0061] Large hole section 1391 and small hole section 1392 are arranged in sequence along the vertical direction, so that the bottom of large hole section 1391 connects with the side of small hole section 1392 to form a step portion 1393. Step portion 1393 is located on both sides of small hole section 1392 along the width direction of connecting plate 131. The cross section of through hole 139 formed by the connection between large hole section 1391 and small hole section 1392 is an inverted "convex" shape.

[0062] By providing the step portion 1393 so that the through hole 139 is in an inverted "convex" shape, not only the material volume at the easily breakable portion 138 is effectively reduced, making it easier to destroy the easily breakable portion 138, but also the strength of the easily breakable portion 138 along the length direction of the connecting plate 131 is ensured, thereby ensuring the reliability of the knock-off structure 130.

[0063] Obviously, this embodiment does not limit the manner in which the knock-off structure 130 realizes the disengagement of the first connection part 111 and the second connection part 121. It is understandable that in some other embodiments, the disengagement of the knock-off structure 130 from the first connection part 111 and the second connection part 121 can be realized as required, for example, by disassembling the knock-off structure 130 from the first connection part 111 and the second connection part 121, thereby realizing the disengagement of the first connection part 111 and the second connection part 121.

[0064] The air-conditioning cabinet 100 provided in this embodiment has a first connecting portion 111 set on the top wall of the front panel lining 110, and a second connecting portion 121 set on the top wall of the air outlet frame 120, and a knock-off structure 130 is set to be connected to the first connecting portion 111 and the second connecting portion 121 at the same time, so as to limit the relative sliding of the air outlet frame 120 and the front panel lining 110, thereby avoiding the air outlet frame 120 sliding relative to the front panel lining 110 during transportation, and then colliding with other components, causing damage to the air outlet frame 120 and other components.

[0065] At the same time, the first connection part 111 and the second connection part 121 are respectively connected to the knock-off structure 130 by snap-fits, which are convenient for installation. The knock-off structure 130 has a breakable part 138. After transportation is completed, the breakable part 138 can be destroyed to quickly separate from the first connection part 111 and the second connection part 121. In this way, the air outlet frame 120 can slide relative to the front panel lining 110, which is convenient for subsequent disassembly and cleaning of the air outlet frame 120.

[0066] 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 scope of protection of the present invention should be based on the scope defined by the claims.
