[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0040] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, the air conditioner 100 according to an embodiment of the present utility model includes: a housing assembly 1 and a protective net 2. The housing assembly 1 forms an airflow channel, and the protective net 2 is disposed in the airflow channel and blocks the airflow channel. The protective net 2 includes a net body and an insulating layer disposed on the outer surface of the net body.

[0042] By setting up a protective net 2 to block the airflow channel, an effective physical barrier is formed between the upstream and downstream sides of the protective net 2, preventing users from coming into contact with moving parts such as the impeller 7 and charged parts inside the air conditioner 100, thereby improving the safety of using the air conditioner 100. Furthermore, by setting an insulating layer on the outer surface of the net body, the insulating layer can effectively block charged particles from contacting the net body. That is, the insulating layer reduces the number of charged particles adsorbed by the net body. In an air conditioner 100 with negative ion sterilization function, this reduces the number of negative ions adsorbed on the protective net 2, thereby improving the negative ion sterilization effect of the air conditioner 100. Therefore, by setting an insulating layer on the outer surface of the net body, while ensuring the protective performance of the protective net 2, the number of negative ions adsorbed on the protective net 2 can be reduced, thereby increasing the concentration of negative ions in the airflow from the air conditioner 100, which is beneficial to improving the negative ion sterilization effect of the air conditioner 100.

[0043] According to the embodiment of the present utility model, the air conditioner 100, by setting an insulating layer on the outer surface of the mesh body, can reduce the number of negative ions adsorbed on the protective mesh 2 while ensuring the protective performance of the protective mesh 2, thereby increasing the concentration of negative ions in the airflow of the air conditioner 100 and improving the negative ion sterilization effect of the air conditioner 100.

[0044] In some embodiments, the mesh body is made of metal, such as wire mesh, which can improve the structural strength and protective effect of the protective mesh 2. Furthermore, an insulating layer covers the outer surface of the mesh body; this insulating layer is a non-metallic coating to ensure its insulating effect.

[0045] According to some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the housing assembly 1 has an air outlet 11 located at the air outlet end of the airflow channel, and a protective net 2 is disposed at the air outlet 11. The airflow within the airflow channel is discharged into the indoor space through the air outlet 11; that is, the airflow channel is connected to the indoor space through the air outlet 11. Therefore, by placing the protective net 2 at the air outlet 11, an effective physical barrier is formed at the connection point between the airflow channel and the indoor space, thereby preventing the user's hands from entering the airflow channel and improving the protective effect of the protective net 2. Furthermore, by placing the protective net 2 at the air outlet 11, the distance between the protective net 2 and the fan wheel 7 of the air conditioner 100 can be increased along the gas flow direction within the airflow channel, reducing the resistance of the protective net 2 to the airflow and thus increasing the air volume of the air conditioner 100 to improve its air conditioning efficiency.

[0046] According to some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the air conditioner 100 also includes a negative ion generator 3, which is located within the airflow channel and upstream of the protective net 2. The negative ion generator 3 releases negative ions into the flowing airflow through high-voltage corona discharge or other methods, thereby purifying the air by removing dust. By placing the negative ion generator 3 upstream of the protective net 2—meaning that the protective net 2 is closer to the air outlet 11 than the negative ion generator 3 in the airflow direction (i.e., the negative ion generator 3 is located on the side of the protective net 2 away from the air outlet 11)—the protective net 2 effectively prevents the user from coming into contact with the negative ion generator 3, thus avoiding the risk of electric shock.

[0047] According to some embodiments of this utility model, the housing assembly 1 has an air outlet 11 located at the air outlet end of the airflow channel, and a protective net 2 is disposed at the air outlet 11. The air conditioner 100 also includes a negative ion generator 3, which is disposed within the airflow channel and located upstream of the protective net 2. Thus, the protective net 2 prevents the user's hand from entering the airflow channel and coming into contact with the negative ion generator 3, thereby avoiding the risk of electric shock and improving the protective effect of the protective net 2. Furthermore, it reduces the resistance of the protective net 2 to the airflow, thereby increasing the air volume of the air conditioner 100 and improving its air conditioning efficiency.

[0048] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the protective net 2 is equipped with a terminal block 21 for grounding. While the insulating layer prevents charged particles from being conducted to the net body, some charged particles may adhere to the outer surface of the insulating layer. Therefore, grounding via the terminal block 21 allows the charged particles attached to the protective net 2 to be transmitted to the ground, thus preventing the accumulation of charged particles on the protective net 2 and the resulting electrostatic discharge.

[0049] According to some embodiments of this utility model, the terminal block 21 is annular and has a first connecting hole 211. A connecting post 13 is formed on the housing assembly 1, and the connecting post 13 has a second connecting hole. Fasteners pass through the first connecting hole 211 and the second connecting hole to connect the terminal block 21 and the connecting post 13. That is, through the cooperation of the first connecting hole 211 and the second connecting hole with the fastener, the connection between the terminal block 21 and the housing assembly 1 can be realized to ensure the stability of the position of the terminal block 21 and enable the terminal block 21 to be stably grounded. In addition, the protective net 2 can be connected to the housing assembly 1 through the terminal block 21, that is, the terminal block 21 simultaneously serves the functions of grounding to release charged particles and fixing the protective net 2.

[0050] According to some embodiments of this utility model, the housing assembly 1 is provided with a plurality of first connecting structures 14, which are distributed on opposite sides of the protective net 2 along its length. The protective net 2 is connected to the housing assembly 1 through at least a plurality of first connecting structures 14. That is, both ends of the protective net 2 along its length are fixed to the housing assembly 1 by the first connecting structures 14 located on the same side, thereby achieving the fixation of both ends of the protective net 2 along its length through the plurality of first connecting structures 14, thus improving the stability of the protective net 2 after installation.

[0051] According to some embodiments of this utility model, the first connecting structure 14 includes a hook 141, and the protective net 2 includes a first protective strip 22 extending along the length direction of the protective net 2, with at least a portion of the first protective strip 22 engaging with the hook 141. That is, the protective net 2 is connected to at least a portion of the first connecting structure 14 via the first protective strip 22. This snap-fit ​​connection method is simple and facilitates disengagement. Therefore, the installation difficulty of the protective net 2 can be reduced, improving the installation efficiency of the protective net 2, and it is also convenient to remove the protective net 2 from the housing assembly 1, reducing the difficulty of subsequent maintenance, cleaning, or replacement.

[0052] According to some embodiments of this utility model, the protective net 2 is provided with multiple first connecting structures 14 on both opposite sides along its length, and the multiple first connecting structures 14 located on the same side are arranged at intervals along the width direction of the protective net 2. That is, both ends of the protective net 2 along its length are connected to the housing assembly 1 through multiple first connecting structures 14 on the same side, i.e., there are multiple connection positions between both ends of the protective net 2 along its length and the housing assembly 1 arranged along the width direction of the protective net 2. As a result, the number of connection positions between the protective net 2 and the housing assembly 1 can be increased, thereby improving the stability of the protective net 2 after installation.

[0053] According to some embodiments of this utility model, such as Figure 2 As shown, the protective net 2 has a first side 2a and a second side 2b on opposite sides along its width. The housing assembly 1 has multiple second connecting structures 15, with each side (first side 2a and second side 2b) also having multiple second connecting structures 15. These multiple second connecting structures 15 located on the same side of the protective net 2 are arranged at intervals along the length of the protective net 2. The protective net 2 is connected to the housing assembly 1 through at least multiple second connecting structures 15. That is, both ends of the protective net 2 along its width are connected to the housing assembly 1 through multiple second connecting structures 15 located on the same side. Thus, the multiple second connecting structures 15 can fix the protective net 2 at opposite ends along its width. Furthermore, both ends of the protective net 2 along its width have multiple connection points arranged along the length of the protective net 2 with the housing assembly 1, thereby increasing the number of connection points between the protective net 2 and the housing assembly 1 and improving the stability of the protective net 2 after installation.

[0054] According to some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the protective net 2 includes multiple second protective strips 23 extending along its width. The second connecting structure 15 includes multiple positioning holes 151 located on the first side 2a. The two ends of the second protective strips 23 are a first end and a second end, respectively, and at least a portion of the first ends of the second protective strips 23 are located within the positioning holes 151. The positioning holes 151 provide a pre-positioning function for the installation of the protective net 2. That is, during installation, the second protective strips 23 are aligned with the corresponding positioning holes 151 and inserted, achieving coarse positioning of the protective net 2 and improving its installation efficiency. Furthermore, the positioning holes 151 limit the movement of at least a portion of the second protective strips 23, restricting the freedom of movement of the protective net 2 in the length and thickness directions, thereby improving the stability of the protective net 2 after installation.

[0055] According to some embodiments of this utility model, a flexible buffer sleeve 24 is provided inside the positioning hole 151, and the flexible buffer sleeve 24 is sleeved on the first end of the second protective strip 23. That is, the flexible buffer sleeve 24 is sleeved on the second end of the second protective strip 23 that is inserted into the positioning hole 151, thereby avoiding direct contact between the second end of the second protective strip 23 and the inner circumferential surface of the positioning hole 151. In other words, it can avoid direct contact between the protective net 2 and the housing assembly 1 to form a rigid connection, thereby avoiding abnormal noise caused by thermal expansion and contraction and friction between the protective net 2 and the housing assembly 1.

[0056] According to some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the second connecting structure 15 also includes a plurality of stops 152 located on the second side 2b. At least a portion of the second protective strip 23 has its second end abutting against the stop 152 along the width direction of the protective net 2. That is, at least a portion of the first end of the second protective strip 23 is inserted into the positioning hole 151, and at least a portion of the second protective strip 23 has its second end abutting against the stop 152 along the width direction of the protective net 2. The stop 152 can effectively prevent the protective net 2 from moving away from the positioning hole 151 along the width direction. In other words, the positioning hole 151 and the stop 152 can form a limit on the protective net 2 along the width direction. Based on the positioning hole 151 restricting the movement of the protective net 2 along the length and thickness directions, a six-way limit can be formed on the protective net 2 by the housing assembly 1 to ensure the secure installation of the protective net 2.

[0057] According to some embodiments of this utility model, the second protective strip 23 that abuts against the stop block 152 is a first fixing strip 23a. The second end of the first fixing strip 23a has a bent portion, which bends towards the first end of the first fixing strip 23a. The bent portion abuts against the stop block 152 along the width direction of the protective net 2. It can be understood that, along the width direction of the protective net 2, the side of the bent portion facing away from the positioning hole 151 is formed as an arc surface. Therefore, by providing the bent portion, the second end of the first fixing strip 23a can make smoother contact with the stop block 152, thus avoiding the second end of the first fixing strip 23a being too sharp and scratching the stop block 152.

[0058] According to some embodiments of this utility model, such as Figure 2 and Figure 6As shown, the second connecting structure 15 also includes a plurality of fixing clips 153 located on the second side 2b. The fixing clips 153 form a clamping space, and at least a portion of the second end of the second protective strip 23 is located within the clamping space. That is, at least a portion of the second end of the second protective strip 23 can be fixed from the second side 2b by the plurality of fixing clips 153 to restrict the movement of the protective net 2 in the length direction. In particular, by fixing the clips 153, the movement of the corresponding second protective strip 23 along the length direction of the protective net 2 can be restricted, thereby improving the limiting and fixing effect of the protective net 2 based on the positioning hole 151, so as to ensure the secure installation of the protective net 2.

[0059] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the housing assembly 1 also has multiple positioning grooves 16 formed on the second side 2b, and at least some of the second ends of the second protective strips 23 pass through the positioning grooves 16 along the width direction of the protective net 2. That is, the multiple positioning grooves 16 can restrict the movement of the second ends of the corresponding second protective strips 23 in the length direction of the protective net 2, thereby restricting the movement of the protective net 2 in the length direction. Thus, based on the positioning holes 151, the limiting and fixing effect on the protective net 2 can be improved to ensure the secure installation of the protective net 2.

[0060] According to some embodiments of this utility model, the second connecting structure 15 further includes a plurality of fixing buckles 153 located on the second side 2b. The fixing buckles 153 form a clamping space, and at least a portion of the second ends of the second protective strips 23 are located within the clamping space. A plurality of positioning grooves 16 are also formed on the housing assembly 1 located on the second side 2b, and at least a portion of the second ends of the second protective strips 23 pass through the positioning grooves 16 along the width direction of the protective net 2. Therefore, the limiting and fixing effect of the housing assembly 1 on the protective net 2 can be better improved, ensuring the secure installation of the protective net 2.

[0061] In a specific example, see Figures 2 to 6As shown, the length direction of the protective net 2 is the first direction, and the width direction of the protective net 2 is the second direction. The protective net 2 is provided with multiple hooks 141 on both sides of the first direction. The multiple hooks 141 on the same side are arranged at intervals along the second direction. The two sides of the protective net 2 along the second direction are the first side 2a and the second side 2b, respectively. The first side 2a is provided with multiple positioning holes 151 arranged at intervals along the first direction. The second side 2b is provided with multiple blocks 152, multiple fixing buckles 153 and multiple positioning grooves 16. The positioning grooves 16 are located on the side of the blocks 152 and the fixing buckles 153 facing the positioning holes 151. Each block 152 corresponds to a positioning groove 16 and each fixing buckle 153 corresponds to a positioning groove 16. The hooks 141 are bent along the second direction toward the direction close to the second side 2b. The two ends of part of the first protective strip 22 are respectively inserted into the hooks 141 on both sides along the first direction. The plurality of second protective strips 23 include a first fixing strip 23a and a second fixing strip 23b. The first section of the first fixing strip 23a is inserted into the positioning hole 151, and the second end of the first fixing strip 23a is located in the positioning groove 16 and abuts against the stop block 152 in the second direction. The portion of the first fixing strip 23a that abuts against the stop block 152 has a bent portion. The first end of the second fixing strip 23b is inserted into the positioning hole 151, and the second end of the second fixing strip 23b is located in the positioning groove 16 and clamped in the clamping space of the fixing buckle 153.

[0062] Specifically, during the installation of the protective net 2, the first ends of multiple second protective strips 23 are aligned with multiple positioning holes 151 and inserted. The first protective strip 22 corresponding to the hook 141 is then inserted into the hook 141 from the opening of the hook 141 along the second direction. The entire protective net 2 is then pushed to move along the second direction toward the positioning hole 151. The first fixing strip 23a and the second fixing strip 23b are aligned and inserted into the corresponding positioning groove 16 until the second end of the first fixing strip 23a abuts against the corresponding stop 152 and the second end of the second fixing strip 23b is inserted into the corresponding clamping space.

[0063] In a specific example, the housing assembly 1 includes an air outlet frame 1a and a volute 1b, which are formed independently. An air outlet 11 is formed on the air outlet frame 1a. A protective net 2 is provided on the side of the air outlet frame 1a facing the volute 1b. A sponge layer is provided on the side of the air outlet frame 1a facing the protective net 2. The sponge layer is used to prevent the air outlet frame 1a from rigidly contacting the volute 1b. After the protective net 2 is installed, the sponge layer can separate the air outlet frame 1a from the protective net 2 to avoid direct contact between the protective net 2 and the air outlet frame 1a, thereby avoiding abnormal noise caused by contact.

[0064] According to some embodiments of this utility model, such as Figure 8 , Figure 9 and Figure 11As shown, the air conditioner 100 also includes a louver mechanism, which includes air guide louvers 41, louver connecting rods 42, and a first driver 43. The airflow channel includes an air outlet channel 12. The air guide louvers 41 and the louver connecting rods 42 are disposed in the air outlet channel 12. The air guide louvers 41 have a fixed part 411, a flexible connecting part 412, and a rotating connecting part 413. The fixed part 411 is fixed to the inner wall of the air outlet channel 12. The flexible connecting part 412 is connected between the fixed part 411 and the rotating connecting part 413. The rotating connecting part 413 is rotatably connected to the louver connecting rods 42. The first driver 43 is used to drive the louver connecting rods 42 to move.

[0065] In other words, the rotating connecting part 413 is flexibly connected to the flexible connecting part 412 and the fixed part 411. The first driver 43 drives the louver connecting rod 42 to move, causing the rotating connecting part 413 to move relative to the fixed part 411, thus making the flexible connecting part 412 swing, thereby adjusting the deflection angle of the flexible connecting part 412. By setting the flexible connecting part 412, the area occupied by the air guide louver 41 in the air outlet duct 12 can be reduced, thereby reducing the resistance of the air guide louver 41 to the air outlet airflow and thus increasing the air volume of the air conditioner 100.

[0066] According to some embodiments of this utility model, the air outlet channel 12 has a first inner wall surface 121 and a second inner wall surface 122 opposite to each other along the width direction of the protective net 2. The louver connecting rod 42 is located on the side of the air guide louver 41 near the first inner wall surface 121, and the rotation axis of the rotating connection part 413 is perpendicular to the first inner wall surface 121. Therefore, the obstruction of airflow by the louver connecting rod 42 in the air outlet direction can be effectively reduced, thereby reducing the resistance of the louver connecting rod 42 to the air outlet airflow and increasing the airflow volume of the air conditioner 100. In a specific example, the thickness direction of the louver connecting rod 42 is parallel to the rotation axis of the rotating connection part 413, that is, the louver connecting rod 42 can be arranged parallel to the first inner wall surface 121 to reduce the resistance of the louver connecting rod 42 to the air outlet airflow.

[0067] According to some embodiments of this utility model, such as Figure 10As shown, the louver connecting rod 42 is provided with a rotating connecting hole 421, and the air guide louver 41 is provided with a rotating connecting shaft 4131. The rotating connecting shaft 4131 is rotatably disposed within the rotating connecting hole 421, and the inner diameter of the rotating connecting hole 421 is larger than the diameter of the rotating connecting shaft 4131. That is to say, the rotating connecting hole 421 can provide a certain amount of room for the rotating connecting shaft 4131 to move, that is, the rotating connecting shaft 4131 can rotate within the rotating connecting hole 421 and can also achieve a certain degree of wobbling. As a result, the contact area between the outer circumferential surface of the rotating connecting shaft 4131 and the inner circumferential surface of the rotating connecting hole 421 can be reduced, thereby reducing the frictional resistance between the rotating connecting shaft 4131 and the inner circumferential surface of the rotating connecting hole 421, and thus reducing the driving force requirement of the first actuator 43.

[0068] According to some embodiments of this utility model, the air outlet duct 12 has a first inner wall surface 121 and a second inner wall surface 122 opposite to each other along the width direction of the protective net 2. The louver connecting rod 42 is located on the side of the air guide louver 41 near the first inner wall surface 121. The rotation axis of the rotating connection part 413 is perpendicular to the first inner wall surface 121. The louver connecting rod 42 is provided with a rotating connection hole 421, and the air guide louver 41 is provided with a rotating connection shaft 4131. The rotating connection shaft 4131 is rotatably disposed in the rotating connection hole 421, and the inner diameter of the rotating connection hole 421 is larger than the diameter of the rotating connection shaft 4131. As a result, the resistance of the louver connecting rod 42 to the air outlet can be reduced, thereby increasing the air outlet volume of the air conditioner 100. Furthermore, the frictional resistance between the rotating connection shaft 4131 and the inner circumferential surface of the rotating connection hole 421 can be reduced, thereby reducing the driving force requirement of the first actuator 43.

[0069] In a specific example, such as Figure 1 , Figure 8 and Figure 9 As shown, the housing assembly 1 includes an air outlet frame 1a and a volute 1b. The air conditioner 100 also includes a fan wheel 7, a guide plate 5, and a second driver 6. The air outlet frame 1a and the volute 1b together define an air outlet channel 12. A first inner wall surface 121 is formed on the air outlet pipe, and a second inner wall surface 122 is formed on the volute 1b. A louver mechanism is disposed on the air outlet frame 1a. The first driver 43 is disposed outside the air outlet channel 12, specifically on the side of the air outlet frame 1a away from the first inner wall surface 121. The guide plate 5 is disposed at the air outlet 11. The protective net 2 is located between the guide louver 41 and the guide plate 5. The second driver 6 is disposed on one side of the air outlet frame 1a along the first direction and is used to drive the guide plate 5 to rotate. In addition, there are multiple negative ion generators 3, which are arranged at intervals along the length of the air outlet 11 and distributed in the gaps between multiple air guide louvers 41 to ensure the uniformity of negative ion concentration. At the same time, the gaps between multiple air guide louvers 41 can be fully utilized for arrangement, resulting in a more compact layout.
