Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a protective component and an air conditioner. Background Art

[0002] As living standards improve, people's expectations for their living environments are becoming increasingly higher. Air conditioners, as household appliances for regulating indoor environments, are becoming increasingly popular. To meet these demands for comfort, air conditioners require high-voltage power supplies to implement additional functions such as air purification and sterilization. However, the probability of electrical faults such as short circuits increases significantly when using high-voltage power, due to factors such as power supply conditions, line shorts, and component aging.

[0003] Air conditioners typically incorporate circuit breakers connected to the power supply and electrical control components to ensure electrical safety. However, these circuit breakers are complex, expensive to manufacture, and complex to install. Furthermore, fuses are made of glass, which can be easily knocked during use and transportation, resulting in poor stability. Currently, there are no protective devices for these fuses. Summary of the Invention

[0004] The problem solved by the present invention is that the fuse in the existing air conditioner is easily damaged during disassembly, assembly and transportation; another problem solved by the present invention is that the conventional protective parts have poor assembly fastness and are easy to loosen and fall out.

[0005] To address the aforementioned issues, the present invention provides a protective member for an air conditioner equipped with a fuse. The protective member comprises a first housing and a second housing that are rotatably connected, with a cavity formed therebetween for accommodating the fuse. This arrangement allows the protective member to be integrated, requiring only a folding operation for assembly, resulting in highly efficient assembly.

[0006] Preferably, a folding edge is provided between one side of the first shell and the second shell, and an assembly structure is provided between the first shell and the second shell on a side away from the folding edge. The folding edge can be provided on either the first shell or the second shell, and has the advantages of a simple structure, a small number of components, low production costs, and convenient assembly.

[0007] Preferably, the assembly structure includes a buckle and a slot, wherein the buckle can be snapped into the slot and limited in position, and the buckle is provided on the first shell and the slot is provided on the second shell, or the buckle is provided on the second shell and the slot is provided on the first shell. This arrangement is simple in structure and convenient and reliable in assembly.

[0008] Preferably, the assembly structure further includes an abutment block located on at least one side of the buckle. Preferably, there are two abutment blocks, symmetrically located on the left and right sides of the buckle. This arrangement can limit the deformation of the second shell during assembly, preventing excessive deformation of the second shell relative to the first shell due to excessive force, thereby damaging the folded edge.

[0009] Preferably, the protective member further includes a relief structure disposed at the end of the accommodating cavity, the relief structure being in communication with the accommodating cavity. The relief structure includes a first notch and a second notch, the first notch being located at one end of the accommodating cavity, and the second notch being located at the other end of the accommodating cavity. The first notch is formed by a recessed portion of the first or second shell, or by the first and second shells cooperating with each other.

[0010] Preferably, the first shell part is recessed downward to form a first cavity, and the second shell part is recessed downward to form a second cavity. The first cavity and the second cavity together form a accommodating cavity. A limiting structure is provided in the first cavity or the second cavity, which has the advantages of simple structure, saving materials and easy assembly.

[0011] Preferably, the limiting structure includes a first limiting member arranged in an arc shape, the first limiting member is coaxial with the accommodating cavity, and the arc α of the first limiting member is 180°-270°. Preferably, the value range of the arc α is 210°<α<240°, which can take into account both the convenience and tightness of assembly.

[0012] Preferably, the first position-limiting member includes a first arm extending into the second cavity, configured to abut and limit the position of the fuse tube. During assembly, the fuse tube is brought into contact with the end of the first arm, and force is applied to the fuse tube to deform the first arm, forcing the fuse tube into the first position-limiting member. The first arm then returns to its original position and abuts and limits the position of the fuse tube.

[0013] Preferably, the first limiting member further includes a second arm arranged opposite to the first arm, the second arm extending into the second cavity, and the first arm and / or the second arm can be brought closer to or separated from each other. This arrangement makes the structure of the first limiting member symmetrical and the appearance beautiful. Preferably, the limiting structure further includes a second limiting member, and the first limiting member and the second limiting member are arranged in the first cavity at intervals. This arrangement can simultaneously limit the two ends of the fuse to prevent it from shaking during transportation and affecting operational stability, while taking into account both the tightness and convenience of assembly.

[0014] Preferably, the outer wall of the first shell and / or the second shell is provided with a plurality of reinforcing ribs, which are arranged at equal intervals along the longitudinal axis of the first shell and / or the second shell. This arrangement can further improve the mechanical strength of the protective element, and has a simple structure and an aesthetically pleasing appearance.

[0015] Compared with the prior art, the protective member described in the present invention has the following beneficial effects: 1) The protective member described in the present invention is connected into one body by folding the edges, and can be assembled only by folding, which makes assembly and disassembly easy; 2) The first limiting member is used to abut and limit the safety tube; there is no need to fix the protective member itself, which can take into account the convenience and tightness of assembly; 3) The structure is simple and easy to produce and process.

[0016] The present invention further provides an air conditioner comprising the protective member. The air conditioner has the same beneficial effects as the protective member, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As people's quality of life improves, their requirements for living environments are becoming increasingly higher. Air conditioners, as a household appliance for regulating the indoor environment, are becoming increasingly popular. To meet more functional requirements, fuses 8 are increasingly being used in air conditioners to ensure electrical safety. To prevent damage from external impacts, protective elements are required around the fuses 8. To this end, the applicant proposes the following technical solution:

[0027] Example 1

[0028] In the prior art, an air conditioner includes electrical equipment, such as an electrical control structure (not shown) and a fuse 8. To prevent damage to the air conditioner caused by electrical faults, one end of fuse 8 is connected to a power source or a transformer, and the electrical control structure is connected to the other end of fuse 8. The electrical control structure is then connected to other electrical equipment, such as a fan or compressor. Fuse 8 is a common commercially available, generally cylindrical fuse. Since wiring connections are often conventional, to avoid redundant description, in this application, the connection between the electrical control structure and fuse 8 is considered to indicate that the two are connected.

[0029] In order to solve the problem that the fuse 8 is easily damaged by impact, this embodiment proposes a protective member, such as Figure 1-3 As shown, the air conditioner is provided with a fuse 8, and the protective member includes a detachably connected first shell 1 and a second shell 2, with a housing 3 formed between the first shell 1 and the second shell 2 for accommodating the fuse 8. As an example of the present invention, a folding edge 22 is provided between the first shell 1 and the second shell 2, and the second shell 2 is rotatably connected to the first shell 1 via the folding edge 22. This arrangement makes the protective member integral, requiring only folding during assembly, which improves assembly efficiency. The folding edge 22 can be provided on either the first shell 1 or the second shell 2. This arrangement has a simple structure, a small number of components, low production costs, and convenient assembly. Annular reinforcing ribs 7 are provided on the outer wall of the first shell 1 and / or the second shell 2, which further enhance the mechanical strength of the protective member. There are multiple reinforcing ribs 7, which are evenly spaced along the long axis of the first shell 1 and / or the second shell 2, resulting in a simple structure and an attractive appearance.

[0030] As an example of the present invention, a portion of the first shell 1 is recessed downward to form a first cavity 11, and a portion of the second shell 2 is recessed downward to form a second cavity 21. The first cavity 11 and the second cavity 21 together form a accommodating cavity 3. A limiting structure 4 is provided in the accommodating cavity 3 to limit and fix the fuse 8. This arrangement is simple in structure, saves materials and is easy to assemble. The limiting structure 4 includes a first limiting member 41, which is arc-shaped and is partially fitted with the first cavity 11; preferably, the first limiting member 41 is coaxial with the accommodating cavity 3 and the arc of the first limiting member 41 is α, and 180°<α<270°; preferably, the value range of the arc α is 210°<α<240°. This arrangement can take into account both the convenience and tightness of assembly.

[0031] The first retaining member 41 includes a first arm 411 extending into the second cavity 21. The first arm 411 is used to retain the fuse 8 in place. During assembly, the fuse 8 is placed against the end of the first arm 411. Force is applied to the fuse 8, causing the first arm 411 to deform and push the fuse 8 into the first retaining member 41. The first arm 411 then returns to its original position and engages with the fuse 8. As another example of the present invention, the first retaining member 41 also includes a second arm 412 positioned opposite the first arm 411. The second arm 412 extends into the second cavity 21, and the first and second arms 411, 412 can move toward or away from each other. During assembly, the fuse 8 is placed between the first and second arms 411, 412, and force is applied downward. At least one of the first and second arms 411, 412, deforms and moves away from each other. After the fuse 8 is pushed into the first retaining member 41, the first and / or second arms 411, 412 return to their original position, securing the fuse 8. Preferably, the limiting structure 4 also includes a second limiting member 42, and the first limiting member 41 and the second limiting member 42 are arranged in the first cavity 11 at intervals. This setting can simultaneously limit the two ends of the fuse 8 to prevent it from shaking during transportation and affecting the stability of operation, taking into account the tightness and convenience of assembly. The structure of the second limiting member 42 is the same as or different from that of the first limiting member 41; as an example of the present invention, the first limiting member 41 is provided with a first arm 411 on the side close to the folding edge 22, the first arm 411 extends into the second cavity 21, and the other side of the first limiting member 41 is flush with the upper edge of the first cavity 11; the first arm 411 and the second arm 412 are respectively provided on both sides of the second limiting member 42, the first arm 411 and the second arm 412 extend into the second cavity 21 and move closer to or separate from each other after being subjected to force. This arrangement can fix the fuse 8 by the second limiting member 42 and simultaneously utilize the first limiting member 41 to assist in fixing it, which saves effort and is convenient and reliable to assemble.

[0032] Preferably, a relief structure 5 is provided at the end of the accommodating cavity 3. The relief structure 5 includes a first notch 51 and a second notch 52. The first notch 51 is located at one end of the accommodating cavity 3, and the second notch 52 is located at the other end of the accommodating cavity 3. The first notch 51 is formed by a partial depression of the first shell 1 or the second shell 2, or alternatively, by the first shell 1 and the second shell 2 cooperating with each other. The second notch 52 has the same structure as the first notch 51 and is also used to pass the wire connected to the fuse 8. A detailed description thereof will not be repeated here.

[0033] Preferably, an assembly structure 6 is provided between the first shell 1 and the second shell 2 on a side away from the folding edge 22. The assembly structure 6 can be a protrusion and a limiting groove / limiting hole or a limiting plate and a slot / jack, etc. Preferably, the assembly structure 5 includes a buckle 61 and a slot 62, the buckle 61 can be snapped into the slot 62 and limited, the buckle 61 is provided on the first shell 1, and the slot 62 is provided on the second shell 2, or the buckle 61 is provided on the second shell 2, and the slot 62 is provided on the first shell 1. Preferably, the buckle 61 is provided on the first shell 1, and the slot 62 is provided on the second shell 2. Preferably, the assembly structure 5 also includes an abutment block 63, and the abutment block 63 is located on at least one side of the buckle 61. Preferably, there are two abutment blocks 63, which are symmetrically provided on the left and right sides of the buckle 61. This arrangement can limit the deformation of the second shell 2 during assembly, preventing the second shell 2 from being excessively deformed relative to the first shell 1 due to excessive force, thereby preventing the folded edge 22 from being damaged.

[0034] Example 2

[0035] After the protective member is opened and closed multiple times, the connection between the first shell 1 and the second shell 2 is not tight, and the buckle 61 is easily loosened and falls out of the slot 62. When the protective member is opened, the protection of the fuse 8 is obviously detrimental, and the user experience is poor. The applicant has made the following technical improvements:

[0036] The limiting structure 4 includes a first limiting member 41 and a first matching member 43 that are relatively arranged. The first limiting member 41 is provided with a first arm 411 on a side away from the folding edge 22. The first matching member 43 is provided with a third arm 431 at a position corresponding to the first arm 411. A pre-tightening structure is provided between the first arm 411 and the third arm 431.

[0037] The pre-tightening structure includes a first clamping block 4111 and a second clamping slot 4312 that cooperates with the first clamping block 4111. The first clamping block 4111 is located on one of the first arm 411 or the third arm 431, and the second clamping slot 4312 is located on the other of the first arm 411 or the third arm 431. Preferably, the pre-tightening structure adopts a mating snap-fit ​​mechanism. The mating snap-fit ​​mechanism means that the first clamping block 4111 is snapped into the second clamping slot 4312, forming a first clamping slot 4112 between the first clamping blocks 4111 and a second clamping block 4311 between the second clamping slots 4312. The second clamping block 4311 is similarly snapped into the first clamping slot 4112. As an example of the present invention, the pre-tightening structure includes a first clamping block 4111 provided on the first arm 411 and a second clamping slot 4312 provided at a corresponding position on the third arm 431; the pre-tightening structure also includes a first clamping slot 4112 provided on the first arm 411 and a second clamping block 4311 provided at a corresponding position on the third arm 431. Preferably, an interference fit is formed between the first clamping block 4111 and the second clamping slot 4312 and / or between the second clamping block 4311 and the first clamping slot 4112. This arrangement can improve the assembly tightness of the pre-tightening structure and prevent loosening during use.

[0038] Preferably, the pre-tightening structure also includes a protrusion 4113 provided on the first arm 411 and / or the third arm 431, so that there is a gap between the first arm 411 and the third arm 431. In other words: the first arm 411 and the third arm 431 are not tightly fitted after assembly. This setting can avoid the assembly strength of the pre-tightening structure being too high, and can take into account both the tightness and convenience of assembly; at the same time, a gap is created between the first shell 1 and the second shell 2, so that slight deformation can occur between the two to improve the tightness of the buckle. Through the cooperation of the assembly structure of the pre-tightening structure, double fixation between the first shell 1 and the second shell 2 is achieved, effectively avoiding loosening and falling out. The protrusion 4113 is provided at the end of the first block 4111. This setting has a simple structure and is easy to produce and process.

[0039] The present invention further provides an air conditioner including the protective member described in this embodiment. The air conditioner may be a cabinet air conditioner, a wall-mounted air conditioner, a ceiling-mounted air conditioner, or the like, preferably a cabinet air conditioner. In addition to the protective member, the air conditioner also includes air conditioning components such as crossflow blades, a motor, an air duct assembly, and an air sweeping structure. The specific structures and assembly relationships of these components are known in the art and are not described in detail here.

[0040] 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.
