DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present disclosure, certain examples of components and arrangements are described. These are, of course, merely examples and are in no way intended to limit the present application. Additionally, the present application can repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and is not intended to indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] For ease of description, spatial relative terms can be used in the description to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0041] The ducted air conditioner, also known as the ducted central air conditioner, is a kind of central air conditioner and an upgrade of the traditional air conditioner. It is composed of one outdoor unit and one indoor unit, and the two are connected by copper pipes, with air as the conveying medium. The ducted air conditioner includes a fan component, an evaporator component, and a frame. The fan component and the evaporator component are installed in the frame. The frame mainly bears the weight of all parts of the indoor unit. The frame is mainly composed of an upper cover plate, a lower cover plate, left and right side plates, and a return air cover plate. Among them, the upper cover plate is the most important. During transportation and installation of the ducted air conditioner, it is lifted by the upper cover plate. Therefore, the upper cover plate needs to bear the weight of the entire machine.

[0042] In the related art, the existing upper cover plate adopts the design of a thick and heavy flat plate to maintain strength, which is not conducive to cost saving, energy saving and material reduction.

[0043] Reference Figure 1 and Figure 2 The present application provides a cover plate 100, which is generally plate-shaped. The cover plate 100 can be made of high-strength and corrosion-resistant materials such as stainless steel, aluminum alloy, etc.

[0044] The cover plate 100 comprises a first side surface 110 and a second side surface 120 oppositely arranged in a first direction X, and a plurality of embossed structures protruding from the first side surface 110 and / or the second side surface 120 are arranged on the cover plate 100, the first side surface 110 and the second side surface 120 are two opposite surfaces of the cover plate 100 along the first direction X, and the plurality of embossed structures are uniformly and spacedly arranged in a second direction Y, and the first direction X intersects the second direction Y.

[0045] In actual use, the first direction X can be the thickness direction of the cover plate 100, the first side surface 110 can be the lower surface of the cover plate 100, the second side surface 120 can be the upper surface of the cover plate 100, and the plurality of embossed structures can be integrally stamped and formed on the cover plate 100. The second direction Y can be the length direction, the width direction or any other direction intersecting the first direction X of the cover plate 100.

[0046] The cover plate 100 provided in the application has the plurality of embossed structures protruding from the first side surface 110 and / or the second side surface 120, so that the cover plate 100 has embossed structures at important mounting or bearing positions, thereby improving the overall rigidity of the cover plate 100. The first side surface 110 and the second side surface 120 are two opposite surfaces of the cover plate 100 along the first direction X, and the plurality of embossed structures are uniformly and spacedly arranged in the second direction Y. Compared with ordinary flat plates, the plurality of embossed structures can improve the strength, the uniform arrangement can disperse the deformation of the cover plate 100, the cover plate 100 can be made thinner, unnecessary material waste is avoided, and costs are saved.

[0047] The height direction of the cover plate 100 is taken as the first direction X, the width direction of the cover plate 100 is taken as the second direction Y, and the length direction of the cover plate 100 is taken as the third direction Z for illustration. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0048] In an embodiment, the plurality of embossed structures comprises a first embossed structure 130, a second embossed structure 140 and a third embossed structure 170. In the second direction Y, the first embossed structure 130 is arranged at the middle of the cover plate 100, and the second embossed structure 140 and the third embossed structure 170 are arranged at two sides of the first embossed structure 130, respectively. Specifically, the machine set is hoisted by the cover plate 100, so the periphery of the cover plate 100 is lifted by the lead screw, and therefore the middle position is relatively weak. Arranging the first embossed structure 130 at the middle of the cover plate 100 can effectively enhance the strength and rigidity of the central region of the cover plate 100, and prevent deformation or damage caused by concentrated load. The second embossed structure 140 and the third embossed structure 170 are arranged at two sides, respectively, to form a substantially symmetrical layout, which is helpful to maintain the overall stability and balance of the cover plate 100 when subjected to force.

[0049] The first profiled structure 130 protrudes from the first side surface 110, and the first profiled structure 130 comprises a first extending part 131 and a plurality of second extending parts 132. The first extending part 131 extends along a third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Each second extending part 132 extends from the first extending part 131 to one side or two sides, and the plurality of second extending parts 132 are arranged at intervals in the third direction Z. Specifically, the first extending part 131 is arranged in a strip shape, and the plurality of second extending parts 132 arranged at intervals can be connected to the same side of the first extending part 131 in the second direction Y to form the first profiled structure 130 in a W shape in a cross section perpendicular to the first direction X. The first extending part 131 extends along the third direction Z, and the plurality of second extending parts 132 make the first profiled structure 130 have a part extending in the second direction Y, so that the first profiled structure 130 as a whole has a plurality of profiled structures extending in different directions. Therefore, the cover plate 100 can more effectively disperse stress when subjected to stress, avoid damage caused by excessive local stress, and improve the anti-deformation and anti-damage capabilities of the cover plate 100.

[0050] The second profiled structure 140 protrudes from the second side surface 120, and the second profiled structure 140 comprises a third extending part 141 and a plurality of fourth extending parts 142. The third extending part 141 extends along the third direction Z, and each fourth extending part 142 extends from the third extending part 141 to one side or two sides, and the plurality of fourth extending parts 142 are arranged at intervals in the third direction Z. Specifically, the third extending part 141 is arranged in a strip shape, and the plurality of fourth extending parts 142 arranged at intervals can be connected to the same side of the third extending part 141 in the second direction Y to form the second profiled structure 140 in a W shape in a cross section perpendicular to the first direction X.

[0051] The first profiled structure 130 and the second profiled structure 140 protrude from the first side surface 110 and the second side surface 120 respectively, so that the cover plate 100 has the first profiled structure 130 and the second profiled structure 140 with opposite profiled directions. Therefore, the strength of the cover plate 100 is further enhanced.

[0052] In the second direction Y, each second extension 132 extends from the first extension 131 to the side close to the third extension 141, and each fourth extension 142 extends from the third extension 141 to the side close to the first extension 131; in the third direction Z, each fourth extension 142 is located between two adjacent second extensions 132. The plurality of fourth extensions 142 are connected to the same side of the third extension 141 close to the first extension 131 in the second direction Y, so that the first profiled structure 130 with a W-shaped cross section and the second profiled structure 140 with a W-shaped cross section are approximately symmetrical in the second direction Y, further balancing the stress distribution on the cover plate 100 and enhancing the overall stability of the structure. And any fourth extension 142 is located between two adjacent second extensions 132 to increase the strength in the intermediate blank position of the two adjacent second extensions 132.

[0053] In an embodiment, the third profiled structure 170 protrudes from the second side surface 120, and the third profiled structure 170 extends in the third direction Z. By protruding the third profiled structure 170 on the second side surface 120, the second profiled structure 140 and the third profiled structure 170 both protrude from the second side surface 120, and the first profiled structure 130 is arranged between the second profiled structure 140 and the third profiled structure 170, so that the profiling directions of the second profiled structure 140, the first profiled structure 130 and the third profiled structure 170 change in turn, further increasing the structural strength of the cover plate 100.

[0054] Reference Figure 1 , Figure 2 and Figure 3 , the cover plate 100 comprises a first end surface 150 and a second end surface 160 arranged opposite in the third direction Z, and the distance between the first profiled structure 130 and the first end surface 150 ranges from 8mm to 12mm. In actual use, the first profiled structure 130 of the cover plate 100 is formed by forcibly deforming the sheet metal part through the combination of the upper and lower molds of the mold; if the distance L between the first profiled structure 130 and the first end surface 150 is less than 8mm, the first end surface 150 will also be pulled by the first profiled structure 130, resulting in sheet metal wrinkles, which not only affects the appearance, but also seriously cracks the sheet metal; if the distance L between the first profiled structure 130 and the first end surface 150 is greater than 12mm, the extension length of the first profiled structure 130 in the third direction Z will be reduced, thereby reducing the strength of the cover plate 100.

[0055] Similarly, the distance between the first profiled structure 130 and the second end surface 160 also ranges from 8mm to 12mm, which will not be described here.

[0056] In an embodiment, the first embossed structure 130 has a recess depth H ranging from 8mm to 10mm, so as to maximize the effect of the first embossed structure 130. If the recess depth H of the first embossed structure 130 is less than 8mm, the cover plate 100 may not have sufficient structural strength to withstand the expected external pressure or load; if the recess depth H of the first embossed structure 130 is greater than 10mm, the overall structural stability of the cover plate 100 may be reduced, and the cover plate 100 is more likely to deform or bend, especially when subjected to external pressure or load. Moreover, an excessively large recess depth means that more material is needed to manufacture the cover plate 100, which not only increases the production cost but also may cause unnecessary material waste.

[0057] With reference to Figure 1 , Figure 2 and Figure 4 , the plurality of embossed structures further include a fourth embossed structure 180 and a fifth embossed structure 190, the fourth embossed structure 180 extending along the third direction Z, and the fifth embossed structure 190 extending along the third direction Z; in the second direction Y, the fourth embossed structure 180, the third embossed structure 170, the first embossed structure 130, the second embossed structure 140 and the fifth embossed structure 190 are sequentially and spacedly arranged. Specifically, the fourth embossed structure 180 adopts a positive and negative embossed design, further improving the overall strength of the cover plate 100.

[0058] The fourth embossed structure 180 includes a fifth extension 181 protruding from the first side surface 110 and a sixth extension 182 protruding from the second side surface 120, and the sixth extension 182 is arranged on the fifth extension 181; the fifth embossed structure 190 includes a seventh extension 191 protruding from the first side surface 110 and an eighth extension 192 protruding from the second side surface 120, and the eighth extension 192 is arranged on the seventh extension 191. By arranging the positive and negative embossed fourth embossed structure 180 and the fifth embossed structure 190 on the cover plate 100, and arranging the first embossed structure 130, the second embossed structure 140 and the third embossed structure 170 between the fourth embossed structure 180 and the fifth embossed structure 190, the cover plate 100 has a plurality of different embossed structures in the second direction Y, further increasing the structural complexity of the cover plate 100, which helps to improve the overall strength.

[0059] The cover plate 100 provided in the application is provided with the first hook mounting position 151 and the second hook mounting position 152 in the first end surface 150 in the second direction Y, and is provided with the third hook mounting position (not shown) and the fourth hook mounting position (not shown) in the second end surface 160 in the second direction Y. The fourth profiling structure 180 is arranged between the first hook mounting position 151 and the third hook mounting position, and the fifth profiling structure 190 is arranged between the second hook mounting position 152 and the fourth hook mounting position. Specifically, the first hook mounting position 151, the second hook mounting position 152, the third hook mounting position and the fourth hook mounting position need to bear a large stress. The fourth profiling structure 180 is arranged between the first hook mounting position 151 and the third hook mounting position, and the fifth profiling structure 190 is arranged between the second hook mounting position 152 and the fourth hook mounting position. After the unit is hoisted, the unit is bent downward under the influence of gravity. The fourth profiling structure 180 and the fifth profiling structure 190 are used to improve the strength of the cover plate 100 during hoisting.

[0060] Reference Figure 5 The embodiment of the application also provides a frame, which comprises a shell 200 and a cover plate 100. The shell 200 comprises a bottom plate 210 and a side plate 220. The bottom plate 210 and the side plate 220 enclose a containing cavity with an opening. The cover plate 100 is arranged on the opening of the containing cavity. The cover plate 100 is arranged on the opening of the containing cavity to form a closed containing cavity, so as to protect the parts in the frame. When the frame is hoisted, the cover plate 100 can bear the weight of the whole frame, so as to simplify the structure of the shell 200 and facilitate transportation.

[0061] Reference Figure 1 、 Figure 5 and Figure 6 The embodiment of the application also provides an air duct machine, which comprises a fan component 300 and a frame. The fan component 300 is contained in the containing cavity. The fan component 300 is the core component of the air duct machine, and is mainly responsible for inhaling and discharging air. The fan component 300 is a machine capable of generating airflow, and air is pushed to flow by rotating blades or turbines. The fan component 300 not only allows air to flow, but also carries pollutants in the air to be discharged outdoors, so as to realize the circulation and renewal of indoor air.

[0062] The side plate 220 is provided with an air outlet 221, and the fan component 300 can drive airflow to be discharged from the air outlet 221.

[0063] The ducted air conditioner provided in the application further comprises an evaporator component (not shown) accommodated in the frame. The main function of the evaporator component is to change the refrigerant from liquid state to gaseous state, during which a large amount of heat is absorbed to cool the air. When the low-temperature condensed liquid passes through the evaporator component, it exchanges heat with the external air, i.e. "vaporization heat absorption", so as to reduce the temperature of the air. This is the basic principle of the ducted air conditioner to output cold air and achieve indoor cooling. When the water vapor in the air meets the low temperature of the surface of the evaporator component, it condenses into water droplets, thereby reducing the humidity in the room.

[0064] In the application, the fan component 300 is installed in the middle of the shell 200, and the first embossed structure 130, the second embossed structure 140 and the third embossed structure 170 are arranged in the middle of the cover plate 100. The strength of the middle of the cover plate 100 is greatly enhanced to support the weight of the whole fan component 300 and reduce the amount of vibration transmitted when the fan component 300 is running. Moreover, the second embossed structure 140 and the third embossed structure 170 protrude from the first side surface 110, increasing the space inside the accommodating cavity. The volume of the fan component 300 and the evaporator component can also be increased, the ability of the fan component 300 to deliver airflow is increased, and the ability of the fan component 300 to cool and heat is also increased. Therefore, the performance of the whole machine can be improved, and the user's experience can be improved.

[0065] Among them, the first hook mounting position 151, the second hook mounting position 152, the third hook mounting position and the fourth hook mounting position are used to install the hook 400. The fourth embossed structure 180 and the fifth embossed structure 190 are designed at the mounting position of the hook 400, which enhances the strength of the position of the hook 400 and ensures that the cover plate 100 does not bend and deform during hoisting of the unit.

[0066] The embossed structures on the cover plate 100 of the application are more evenly distributed. Deep drawing or positive and negative embossing or irregular shaped embossing is used at important mounting or bearing positions. The overall stiffness is stronger. The use of such embossing can make the material thinner, which meets the development trend of energy saving and material reduction.

[0067] In actual use, the ducted air conditioner is connected with four rods protruding from the ceiling to realize installation of the ducted air conditioner. During installation of the ducted air conditioner, the cover plate 100 is hoisted and needs to bear the weight of the whole machine. The cover plate 100 of the application can meet the strength requirements of the cover plate 100 under low thickness of the plate, which saves energy and materials and saves costs. It can also reduce the overall weight of the ducted air conditioner, reduce the burden of the installation workers and improve the installation efficiency.
