Description

Technical Field

[0001] This invention relates to the field of air conditioning, and more specifically, to a digging structure and an air conditioner having the same. Background Technology

[0002] In existing technologies, the outdoor unit casing of multi-split air conditioners typically has perforations at the condenser fins to facilitate heat exchange. To prevent air leakage, the front panel is often a single, closed sheet metal panel without holes. Due to the large size of multi-split outdoor units, the casing is also large, and the panel is also large. The completely closed, holeless panel lacks handles, or some panels have various shaped moldings to increase panel strength, making them impossible to grip. This makes it very inconvenient to install, remove, or take out the front panel. In addition, the panel is often installed using a snap-fit ​​structure. Since there are no handles on the panel, panel assembly is very inconvenient. It is difficult for a single person to operate during assembly, resulting in a poor assembly experience and low efficiency. Summary of the Invention

[0003] The problem solved by this invention is that in the prior art, the outdoor unit of a multi-split air conditioner does not have a gripper structure, making panel assembly very inconvenient. During assembly, it is difficult for a single person to operate, resulting in a poor assembly experience and low efficiency.

[0004] To address the aforementioned problems, the present invention provides a digging hand structure, including a panel and a digging hand disposed on the panel. The digging hand includes a folded edge portion and a digging hand portion. The digging hand portion has a digging hand cavity with one open side, which is used for gripping operation. The folded edge portion surrounds the opening of the digging hand cavity in the circumferential direction and extends outwards away from the opening of the digging hand cavity. A slot is provided between the folded edge portion and the digging hand portion, and the slot engages with the panel to mount the digging hand on the panel.

[0005] In this configuration, a digger is installed on the panel. When the panel needs to be assembled or disassembled, the digger applies an upward or downward force to the panel, thereby making it easier to install or remove the panel. This significantly improves the assembly or maintenance efficiency of the panel. The digger is fixedly installed on the panel by the slot. The assembly of the digger and the panel can be completed without the need for additional complex connection structures. The structure is simple and easy to manufacture.

[0006] Furthermore, the excavator includes an excavator plate, side plates, and an arc-shaped plate. The excavator plate includes an upper buckle plate and a lower buckle plate. One end of the upper buckle plate is connected to the folded edge, and the other end extends upward at an angle away from the folded edge and is connected to one end of the arc-shaped plate. One end of the lower buckle plate is connected to the folded edge, and the other end extends downward at an angle away from the folded edge and is connected to the other end of the arc-shaped plate. The side plates are disposed on both sides of the excavator plate and the arc-shaped plate, and the side plates, together with the excavator plate and the arc-shaped plate, form the excavator cavity.

[0007] The upward tilt of the upper buckle plate helps to exert upward force when gripping, thereby removing the panel from the outdoor unit for corresponding maintenance work. The downward tilt of the lower buckle plate helps to exert downward force when gripping, so that the panel clips are fastened to the outdoor unit, completing the assembly of the panel. The curved plate bends away from the folded edge, which can effectively expand the space of the hand-digging cavity, which is beneficial to the user's gripping operation.

[0008] Furthermore, the angle formed by the upper buckle plate, the lower buckle plate and the folded edge is the same, denoted as α, and the value of α ranges from 20° to 70°.

[0009] When the included angle α is within the above range, the user can easily grasp the excavator and apply force. When the angle is too small, the upper and lower buckles are too close to the panel, which is not conducive to the installation and disassembly of the excavator and may also make the excavator cavity too narrow, which is not conducive to the user's gripping operation. When the angle is large, the upper and lower buckles are close to the horizontal state, which is not conducive to the user's hand to apply force when gripping, affecting the efficiency of assembly or disassembly.

[0010] Furthermore, a flange is provided on the side of the excavator plate near the folded edge, and a groove is formed between the flange and the folded edge.

[0011] Due to the inclined arrangement of the upper and lower buckle plates, the gap between the excavator plate and the folded edge gradually widens, that is, the width of the slot gradually widens, which is not conducive to the snapping with the panel. By setting the flange, the width of the slot is kept stable, thereby ensuring a stable connection between the excavator and the panel.

[0012] Furthermore, the arc-shaped plate includes an upper arc plate and a lower arc plate, and a contraction section is provided between the upper arc plate and the lower arc plate. One end of the upper arc plate is connected to the upper buckle plate, and the other end is connected to the contraction section. One end of the lower arc plate is connected to the lower buckle plate, and the other end is connected to the contraction section. The contraction section protrudes towards the folded edge.

[0013] The excavator's hand chamber is divided into an upper excavator hand chamber and a lower excavator hand chamber by the arrangement of an upper arc plate, a lower arc plate, and a contraction section. The upper excavator hand chamber is formed by the upper arc plate, an upper buckle plate, a side plate, and a contraction section, while the lower excavator hand chamber is formed by the lower arc plate, a lower buckle plate, a side plate, and a contraction section. The upper arc plate can expand the space of the upper excavator hand chamber, and the lower arc plate can expand the space of the lower excavator hand chamber, which is beneficial for the user's grip during operation.

[0014] Furthermore, a drainage hole is provided at the connection between the upper buckle plate and the arc-shaped plate to prevent water from accumulating in the excavator.

[0015] When the outdoor unit is in rainy or snowy weather, water can easily accumulate in the excavator's cavity. If it is not drained in time, it will corrode the panel, reducing its protective effect and service life. The drainage hole can drain the water in time, effectively avoiding the above situation.

[0016] Furthermore, a drainage hole is also provided at the connection between the lower buckle plate and the arc-shaped plate. The drainage hole is used to prevent water accumulation after the excavator is installed backwards.

[0017] In the process of high efficiency and speed, it is difficult to avoid the situation where the excavator is installed upside down. The drainage hole is also provided at the connection between the lower buckle plate and the arc plate to form an effective anti-foolproof design, so that the excavator forms a symmetrical structure, thereby avoiding the hidden danger of water accumulation in the excavator due to installation upside down.

[0018] Furthermore, a recessed mounting hole is provided on the panel for installing the excavator, and a recessed plate is provided in the recessed mounting hole, with the slot engaging with the recessed plate.

[0019] The mounting holes for the recessed platform are simple to design and easy to manufacture, requiring only stamping to form without the need for additional connecting structures.

[0020] Furthermore, the depth of the recessed mounting hole is equal to the thickness of the folded edge.

[0021] This configuration ensures that when the excavator is placed on the panel, the outer surface of the folded edge is flush with the outer surface of the panel, thus keeping the outer surface of the panel flat.

[0022] The present invention also discloses an air conditioner, which includes the excavator structure described above.

[0023] The air conditioner has the same advantages over the prior art as the excavator structure described above, and will not be repeated here.

[0024] Compared to existing technologies, the excavator structure and air conditioner with the same structure provided by this invention have the following advantages: The excavator on the panel allows for assembly of the air conditioner panel by a single person, greatly improving assembly efficiency and reducing production costs. The upper and lower excavator chambers allow for disassembly and maintenance of the air conditioner panel, while the lower chamber is used for assembling the panel's upper clips. A single component satisfies both assembly and disassembly requirements. Furthermore, the upper and lower drainage holes prevent water accumulation if the excavator is installed incorrectly. The fitting of the excavator's upper slot with the panel's recessed platform simplifies the installation process while maintaining the aesthetic appeal of the outer surface. This invention has a simple structure, is easy to install, and significantly improves the installation efficiency of air conditioner panels. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] In existing technology, the panel 2 of the outdoor unit 1 of an air conditioner typically does not have a gripping structure. In some models, to enhance the strength of the panel 2, some protrusions or recesses are formed on the panel 2. These protrusions or recesses are small and cannot be gripped. Therefore, during installation, it is necessary to grip the side of the panel 2 for assembly. Figure 6 , Figure 7 As shown, panel 2 is usually assembled using panel clips 22. During assembly, it is necessary to press vertically downwards to complete the engagement of panel clips 22. Because panel 2 is relatively thin, it is not easy to exert force on its side when gripping, resulting in a slow assembly speed. In addition, the outdoor unit 1 of the multi-split air conditioner is relatively large. When assembling panel 2, it is difficult for a single person to grasp the side and align the panel clips 22, making it difficult to complete the assembly. When disassembly and maintenance are required, there is nowhere on panel 2 to grip and exert force, making it difficult to remove and inconvenient to operate.

[0041] The following describes in detail, with reference to the accompanying drawings, an excavator structure and an air conditioner having the same structure as embodiments of the present invention.

[0042] Example 1

[0043] This embodiment provides a digging hand structure, such as Figure 1-5 , Figure 11 , Figure 12As shown, the device includes a panel 2 and a digger 3 disposed on the panel 2. The digger 3 includes a folded edge portion 31 and a digger portion 32. The digger portion 32 has a digger cavity with one open side, which is used for gripping operation. The folded edge portion 31 surrounds the opening of the digger cavity and extends outwards away from the opening of the digger cavity. A slot 33 is provided between the folded edge portion 31 and the digger portion 32. The slot 33 engages with the panel 2 to hold the digger 3 on the panel 2. In this configuration, a digger 3 is provided on the panel 2. When the panel 2 needs to be assembled or disassembled, the digger 3 applies an upward or downward force to the panel 2, thereby easily installing or removing the panel 2. This significantly improves the assembly or maintenance efficiency of the panel 2. The digger 3 is fixedly mounted on the panel 2 through the slot 33, eliminating the need for additional complex connection structures to complete the assembly of the digger 3 and the panel 2. The structure is simple and easy to manufacture. It should be understood that after the snap-fit ​​is completed, the digger part 32 is set... The inner side of the panel 2 and the folded edge 31 are located on the outer side of the panel 2. This arrangement helps to ensure that when the panel 2 needs to be lifted or pulled down, the fingers and palms are on both sides of the panel 2, and the force can be directly applied to the panel 2. There is no need to use high-strength materials to make the digging handle 3, which reduces its production cost. If the digging handle 32 is located on the outer side of the panel 2, the force when lifting or pulling down must be transmitted through the digging handle 32, which can easily lead to damage to the digging handle 32. Using high-strength materials to make it would easily cause a significant increase in cost.

[0044] As an embodiment of the present invention, such as Figure 4 , Figure 5As shown, the excavator part 32 includes an excavator plate 321, a side plate 322, and an arc-shaped plate 323. The excavator plate 321 includes an upper buckle plate 3211 and a lower buckle plate 3212. One end of the upper buckle plate 3211 is connected to the folded edge part 31, and the other end extends upward at an angle away from the folded edge part 31 and is connected to one end of the arc-shaped plate 323. One end of the lower buckle plate 3212 is connected to the folded edge part 31, and the other end extends downward at an angle away from the folded edge part 31 and is connected to the other end of the arc-shaped plate 323. The side plate 322 is disposed on both sides of the excavator plate 321 and the arc-shaped plate 323. The side plate 322, the excavator plate 321, and the arc-shaped plate 323 surround the excavator cavity. The upward tilt of the upper buckle 3211 helps to exert upward force when gripping, thereby removing the panel 2 from the outer unit 1 for corresponding maintenance work. The downward tilt of the lower buckle 3212 helps to exert downward force when gripping, so that the panel buckle 22 is fastened to the outer unit 1, completing the assembly of the panel 2. The curved plate 323 bends away from the folded edge 31, which can effectively expand the space of the hand-digging cavity, which is beneficial to the user's gripping operation.

[0045] In some optional embodiments, the included angle formed by the upper buckle plate 3211, the lower buckle plate 3212 and the folded edge portion 31 is the same, denoted as α. The value of α is between 20° and 70°, preferably 30° or 45°. It should be noted that the included angle specifically refers to the included angle formed between the outer surface of the upper buckle plate 3211 and the folded edge portion 31, and the included angle formed between the outer surface of the lower buckle plate 3212 and the folded edge portion 31. The outer surface of the upper buckle plate 3211 and the lower buckle plate 3212 refers to the side of the upper buckle plate 3211 and the lower buckle plate 3212 away from the digging hand cavity. When the included angle α is within the above range, the user can easily grasp the digging hand 3 and apply force. When the angle is too small, the upper buckle plate 3211 and the lower buckle plate 3212 are too close to the panel 2, which is not conducive to the installation and disassembly of the digging hand 3, and may also lead to the digging hand cavity being too narrow, which is not conducive to the user's gripping operation. When the angle is large, the upper buckle plate 3211 and the lower buckle plate 3212 are close to the horizontal state, which is not conducive to the user's hand to apply force when gripping, affecting the efficiency of assembly or disassembly.

[0046] Specifically in this embodiment, such as Figure 2-5As shown, a flange 325 is provided on the side of the excavator plate 321 near the folded edge 31, forming a groove 33 between the flange 325 and the folded edge 31. Due to the inclined arrangement of the upper buckle plate 3211 and the lower buckle plate 3212, the gap between the excavator plate 321 and the folded edge 31 gradually widens, that is, the width of the groove 33 gradually widens, which is not conducive to the engagement with the panel 2. The flange 325 ensures that the width of the groove 33 remains stable, thereby guaranteeing a stable connection between the excavator 3 and the panel 2.

[0047] In this embodiment, as Figure 4 As shown, the arc-shaped plate 323 includes an upper arc plate 3231 and a lower arc plate 3232. A contraction section 3233 is provided between the upper arc plate 3231 and the lower arc plate 3232. One end of the upper arc plate 3231 is connected to the upper buckle plate 3211, and the other end is connected to the contraction section 3233. One end of the lower arc plate 3232 is connected to the lower buckle plate 3212, and the other end is connected to the contraction section 3233. The contraction section 3233 protrudes towards the folded edge portion 31. Generally, the distance between the upper snap plate 3211 and the lower snap plate 3212 is relatively large. When using an arc-shaped plate 323, the top of the arc is located in the middle of the upper snap plate 3211 and the lower snap plate 3212. This results in the arc of the arc plate 323 being too large in the middle, occupying too much internal space of the air conditioner, but failing to effectively expand the hand-removal cavity space near the upper snap plate 3211 and the lower snap plate 3212. In this embodiment, the upper arc plate 3231, the lower arc plate 3232, and the contraction section 3... The 233 configuration divides the digging hand cavity into an interconnected upper digging hand cavity and a lower digging hand cavity. The upper digging hand cavity is formed by an upper arc plate 3231, an upper buckle plate 3211, a side plate 322, and a contraction section 3233. The lower digging hand cavity is formed by a lower arc plate 3232, a lower buckle plate 3212, a side plate 322, and a contraction section 3233. The upper arc plate 3231 can expand the space of the upper digging hand cavity, and the lower arc plate 3232 can expand the space of the lower digging hand cavity, which is beneficial for the user's grip during operation.

[0048] As an embodiment of the present invention, such as Figure 5 As shown, a drainage hole 324 is provided at the connection between the upper buckle plate 3211 and the arc-shaped plate 323. The drainage hole 324 is used to prevent water from accumulating in the excavator handle 3. When the outdoor unit 1 is in rainy or snowy weather, water easily accumulates in the excavator handle cavity. If it is not drained in time, it will corrode the panel 2, reducing its protective effect and service life. The drainage hole 324 can drain the water in time, effectively avoiding the above situation.

[0049] In a preferred embodiment, a drainage hole 324 is also provided at the connection between the lower retaining plate 3212 and the arc-shaped plate 323. The drainage hole 324 is used to prevent water accumulation after the excavator 3 is installed backwards. In efficient and rapid processes, it is difficult to avoid the situation where the excavator 3 is installed backwards. Providing a drainage hole 324 at the connection between the lower retaining plate 3212 and the arc-shaped plate 323 can form an effective foolproof design, making the excavator 3 form a symmetrical structure, thereby avoiding the hidden danger of water accumulation in the excavator 3 due to backward installation.

[0050] Specifically in this embodiment, such as Figure 6-10 As shown, a countersunk mounting hole 21 is provided on the panel 2. The countersunk mounting hole 21 is used to install the excavator 3. A countersunk plate 211 is provided in the countersunk mounting hole 21, and the slot 33 is engaged with the countersunk plate 211. The countersunk mounting hole 21 is simple to design and easy to manufacture, and can be formed by stamping without the need for additional connecting structures. It should be noted that when the engagement is completed, the folded edge 31 is located in the stepped hole formed by the countersunk plate 211 and the outer surface of the panel 2.

[0051] As an optional embodiment, the recessed depth of the recessed mounting hole 21 is equal to the thickness of the folded edge portion 31. It should be noted that the recessed depth refers to the distance between the outer surface of the panel 2 and the surface of the recessed plate 211 closest to the outer surface of the panel 2. The outer surface refers to the side that is conventionally away from the inside of the outdoor unit 1. This arrangement ensures that when the excavator 3 is placed on the panel 2, the outer surface of the folded edge portion 31 is flush with the outer surface of the panel 2, so that the outer surface of the panel 2 is in a flat state.

[0052] In a preferred embodiment, a support portion 3221 is provided at the connection between the side plate 322 and the folded edge portion 31. When the excavator 3 is installed on the panel 2, the support portion 3221 abuts against the recessed plate 211, restricting the displacement of the excavator 3. Figure 3 , Figure 4 As shown, the support part 3221 has a semi-cylindrical structure. The support part 3221 can enhance the connection strength between the side plate 322 and the folded edge part 31 on the one hand, and prevent the excavator 3 from shifting after installation on the other hand, thereby strengthening the connection stability between the panel 2 and the excavator 3.
