[0040] The present embodiment provides a top cover plate for an air conditioner, which has improved strength and can improve the problem of deformation and damage caused by impacts such as jumping and stepping.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] The air conditioner of this embodiment includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by a refrigerant pipeline; wherein the outdoor unit includes a casing, a fan assembly and a heat exchange module, wherein the casing includes an outer casing and a top cover plate 010 (such as Figure 1 As shown), the fan assembly and the heat exchange module are assembled in the shell, and the top cover plate 010 is arranged above the fan assembly and the heat exchange module. The fan assembly includes a fan and a motor connected to the fan transmission, and a motor frame for assembling the motor, and the top cover plate is spaced apart from the motor frame.

[0043] Optionally, the distance between the top cover plate and the motor frame is less than or equal to 3 mm, for example, 3 mm, 2 mm, 1 mm, etc., which is not specifically limited here.

[0044] Of course, in other embodiments, the top cover plate may also abut against the motor frame, that is, the distance between the top cover plate and the motor frame is 0 mm.

[0045] It should be noted that the indoor unit may refer to an indoor wall-mounted unit, an indoor cabinet unit or a multi-split unit, etc., and is not specifically limited here; the specific structure of the indoor unit is similar to the related technology and will not be repeated here.

[0046] In order to improve the problem that the top cover plate 010 is easily dented, deformed and damaged due to impact such as jumping and stepping; please refer to Figure 1 , Figure 2 and Figure 3 The top cover plate 010 of this embodiment includes a cover plate body 100 , and the cover plate body 100 includes a plurality of arcuate ribs 110 connected in sequence, and the plurality of arcuate ribs 110 are arranged in sequence along the width extension direction of the cover plate body 100 .

[0047] A plurality of arcuate ribs 110 connected in sequence are provided to prevent stress from being concentrated when the top cover plate 010 is impacted, thereby enhancing the structural strength of the top cover plate 010 and preventing the top cover plate 010 from being deformed or damaged when it is impacted by jumping or stepping on.

[0048] Furthermore, the arc convex surfaces of the multiple arc ribs 110 are distributed toward the same side; specifically, the arc convex surfaces of the multiple arc ribs 110 together constitute the upper surface of the cover body 100, and the arc concave surfaces of the multiple arc ribs 110 together constitute the lower surface of the cover body 100.

[0049] Such arrangement, on the one hand, can enhance the structural strength of the top cover plate 010, prevent stress from being concentrated when the top cover plate 010 is impacted, and improve the problem that the top cover plate 010 is easily deformed and damaged due to impacts such as jumping and stepping; on the other hand, it can ensure the structural regularity and aesthetics of the top cover plate 010, and on the other hand, it is convenient for processing the top cover plate 010, for example, it is convenient to separate from the stamping die after stamping to form a plurality of arc-shaped ribs 110.

[0050] Of course, in other embodiments, the orientation of the arcuate convex surface of some arcuate ribs 110 may be opposite to the orientation of the arcuate convex surface of other arcuate ribs 110 , which is not specifically limited here.

[0051] The specific number of the arcuate ribs 110 can be selected as needed; in this embodiment, the cover plate body 100 includes 7 arcuate ribs 110, which are connected in sequence to form a cover plate body 100 with a wavy cross section in the width direction of the arcuate ribs 110. By setting the cross section of the cover plate body 100 to be wavy, the problem of stress concentration can be effectively improved, thereby improving the problem of the top cover plate 010 being dented, deformed, and damaged due to impact such as jumping and stepping.

[0052] Of course, in other embodiments, the number of the arc-shaped ribs 110 may also be two, three, four, five, six, eight, etc., which is not specifically limited here.

[0053] The radius of the arc rib 110 can be set as required, for example: 35-45mm; please refer to Figure 4 and Figure 5In this embodiment, the arc radius R1 of the arc rib 110 is 40 mm. Optimizing the size of the arc rib 110 can further ensure the structural strength of the top cover plate 010, thereby improving the problem that the top cover plate 010 is easily deformed and damaged due to impacts such as jumping and stepping.

[0054] It should be understood that in other embodiments, the arc radius of the arc-shaped rib 110 can also be 35 mm, 37 mm, 39 mm, 41 mm, 43 mm, 45 mm, etc., which is not specifically limited here.

[0055] The distance between the vertices of the arc convex surfaces of two adjacent arc-shaped ribs 110 can be set as needed, for example: 30-40mm; please refer to Figure 4 In this embodiment, the distance D1 between the vertices of the arc convex surfaces of two adjacent arc-shaped ribs 110 is 35 mm. Optimizing the distance between two adjacent arc-shaped ribs 110 can ensure the structural strength of the top cover plate 010, thereby improving the problem that the top cover plate 010 is easily deformed and damaged due to impacts such as jumping and stepping.

[0056] It should be understood that in other embodiments, the distance between the vertices of the arc convex surfaces of two adjacent arc-shaped ribs 110 can also be 30 mm, 32 mm, 34 mm, 36 mm, 38 mm, 40 mm, etc., which is not specifically limited here.

[0057] Optionally, see Figure 3 and Figure 5 The cover body 100 further includes a transition plate 120, and two adjacent arc-shaped ribs 110 are connected by the transition plate 120. The provision of the transition plate 120 can ensure that the stress of the top cover 010 is not easily concentrated when it is subjected to impacts such as jumping and stepping, thereby improving the problem that the top cover 010 is easily deformed and damaged.

[0058] It should be understood that in other embodiments, two adjacent arc-shaped ribs 110 may be directly connected without being connected through the transition plate 120 .

[0059] The shape of the transition plate 120 can be set as needed; in this embodiment, the transition plate 120 is arc-shaped, the length extension direction of the transition plate 120 is parallel to the length extension direction of the arc-shaped rib 110, and the arc concave surface of the transition plate 120 is opposite to the arc concave surface of the arc-shaped rib 110. Such a setting can ensure that the cover plate body 100 is wavy, so as to further ensure that when the top cover plate 010 is impacted, stress is not easy to concentrate, that is, the structural strength of the top cover plate 010 can be effectively improved, and the problem of deformation and damage of the top cover plate 010 due to impact such as jumping and stepping can be improved.

[0060] Of course, in other embodiments, the transition plate 120 may also be a flat plate, which is not specifically limited here.

[0061] Furthermore, the connection between the transition plate 120 and the arc-shaped rib 110 is a smooth transition, so as to effectively improve the problem of stress concentration.

[0062] The radius of the transition plate 120 can be set as required, for example: 6-10 mm; please refer to Figure 5 In this embodiment, the arc radius R2 of the transition plate 120 is 8 mm. Optimizing the size of the transition plate 120 can further ensure the structural strength of the top cover plate 010, thereby improving the problem that the top cover plate 010 is easily deformed and damaged due to impacts such as jumping and stepping.

[0063] It should be understood that in other embodiments, the arc radius of the transition plate 120 may also be 6 mm, 7 mm, 9 mm, 10 mm, etc., which is not specifically limited herein.

[0064] Please refer to Figure 2 The top cover plate 010 of this embodiment further includes a hand-digging portion 130, which is connected to the cover plate body 100 and is distributed at one end of the length extension direction of the arc-shaped rib 110. The hand-digging portion 130 is provided to facilitate the transportation and movement of the top cover plate 010, and also facilitate the transportation of the air conditioner provided with the top cover plate 010.

[0065] For further information, please refer to Figure 1 and Figure 2 The cover body 100 has a first end and a second end that are relatively distributed, the hand digging portion 130 is connected to the first end, at least one arcuate rib 110 extends to the hand digging portion 130, one end of the remaining arcuate ribs 110 extends to the first end, and the other end of the remaining arcuate ribs 110 extends to the second end. Extending some of the arcuate ribs 110 to the hand digging portion 130 can increase the connection strength between the hand digging portion 130 and the cover body 100, so as to improve the problem that the hand digging portion 130 is easily deformed, broken or damaged relative to the cover body 100.

[0066] Furthermore, in the length extension direction of the arcuate ribs 110, each arcuate rib 110 and the transition plate 120 opposite to the digging portion 130 are extended to the digging portion 130. Such an arrangement makes it possible to form no step between the digging portion 130 and the cover plate body 100, which can effectively enhance the connection strength between the digging portion 130 and the cover plate body 100, so as to improve the problem that the connection between the digging portion 130 and the cover plate body 100 is easy to break, that is, the overall structural strength of the top cover plate 010 is effectively enhanced, so that the top cover plate 010 is not easily deformed or damaged.

[0067] Exemplarily, the hand-digging portion 130 of this embodiment roughly corresponds to the three arc-shaped ribs 110 and the two transition plates 120 between the three arc-shaped ribs 110 .

[0068] Of course, in other embodiments, the number of arc-shaped ribs 110 corresponding to the hand-digging portion 130 can also be one, two, four, etc., and the number of transition plates 120 can vary with the number of arc-shaped ribs 110, for example: one less, one more, two more, etc., compared to the number of arc-shaped ribs 110, and no specific limitation is made here.

[0069] Please refer to Figure 1 and Figure 5 The top cover plate 010 of this embodiment further includes a side plate 140, which is connected to the outermost arc rib 110 among the plurality of arc ribs 110, and the side plate 140 is distributed on one side in the width direction of the arc rib 110 connected thereto, that is, the side plate 140 is connected to one side in the width direction of the cover plate body 100. The side plate 140 is connected to the side edge of the cover plate body 100, so that the top cover plate 010 is easily assembled on the housing of the air conditioner, that is, the easy assembly of the top cover plate 010 is ensured.

[0070] The thickness of the side plate 140 and the arc-shaped rib 110 can be selected as needed, for example, the thickness of at least one of the side plate 140 and the arc-shaped rib 110 is 0.4-0.8 mm. Optimizing the thickness of at least one of the side plate 140 and the arc-shaped rib 110 can ensure the structural strength of the top cover 010, improve the problem of the total weight of the top cover 010 itself, and help avoid the cost increase caused by excessive input of raw materials for producing the top cover 010.

[0071] Please refer to Figure 5 In this embodiment, the thickness H of the side plate 140 and the arc-shaped rib 110 is 0.6 mm ( Figure 5 Only the thickness H of the side plate 140 is indicated in FIG. 1 ). It should be understood that in other embodiments, the thickness of at least one of the side plate 140 and the arc-shaped rib 110 may be 0.4 mm, 0.5 mm, 0.7 mm, 0.8 mm, etc., which is not specifically limited herein.

Optimizing the height difference between the side plate 140 and the arc rib 110 can ensure the structural strength of the top cover plate 010 and improve the problem that the top cover plate 010 is easily deformed and damaged under impact such as jumping and stepping.

[0073] It should be understood that in other embodiments, the height difference between the upper surface of the side panel 140 and the vertex of the arc convex surface of the arc rib 110 can also be 3.5mm, 3.6mm, 3.8mm, 3.9mm, 4.1mm, 4.3mm, 4.5mm, etc., which is not specifically limited here.

[0075] Optionally, see Figure 5 The top cover plate 010 further includes a flange 150, which is connected to the side of the side plate 140 away from the cover plate body 100 and is distributed at an angle with the side plate 140, and the angle includes but is not limited to 90°, 93°, 88°, etc. The setting of the flange 150 can ensure the ease of operation and stability of the top cover plate 010 when assembled on the housing, and ensure the structural stability of the top cover plate 010.

[0076] Optionally, the flange 150 includes a first plate 151 and a second plate 152, wherein the first plate 151 is connected to a side of the side plate 140 away from the cover body 100 and is distributed at an angle to the side plate 140, and the second plate 152 is connected to an end of the first plate 151 away from the side plate 140 and is distributed in a stacked manner with the first plate 151. This arrangement ensures the structural stability of the flange 150, so that the end of the flange 150 away from the side plate 140 is not easily damaged or curled.

[0077] Optionally, the connection between the first plate 151 and the side plate 140 is an arc transition. This arrangement can improve the structural strength and improve the problem of stress concentration.

[0078] Optionally, see Figure 1 and Figure 3 The top cover plate 010 further includes an end plate 160, which is connected to the end of the cover plate body 100 along the length extension direction of the arc-shaped ribs 110. Specifically, all the arc-shaped ribs 110 and all the transition plates 120 are connected to the end plate 160. This arrangement ensures the structural stability of the top cover plate 010 on the one hand, and ensures that the top cover plate 010 is easily and stably assembled on the housing on the other hand.

[0079] Furthermore, the top cover includes two end plates 160, which are respectively connected to the two ends of the cover body 100; the two ends of the side plate 140 in the length extension direction and the two ends of the flange 150 in the length extension direction are also respectively connected to the two end plates 160. In this way, a cavity is formed between the end plates 160, the flange 150, the side plates 140 and the cover body 100. When the top cover 010 is assembled to the shell, the top end of the shell can be inserted into the cavity, and then at least one of the flange 150 and the end cover is connected to the shell to ensure the stability of the assembly.

[0080] It should be noted that the connection method between at least one of the flange 150 and the end cover and the housing includes but is not limited to connection or clamping with fasteners such as bolts.
