Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an air conditioner. Background Art

[0002] At present, there are usually two forms of fixed structure of the fan system of the outdoor unit of the side-outlet air conditioner: one form is to divide the fan duct system into two parts: one part is the fan system, that is, the axial fan, the motor, and the motor bracket are combined into a component and fixed on the bottom plate of the air conditioner; the other part is the duct system, that is, the front cover of the air conditioner with a guide ring. Another form is to take the fan system as a whole, that is, the guide cover, the axial fan, the motor, and the motor bracket are combined into an independent component. For the first form, the fan system and the duct system are separate components, which is time-consuming during assembly and cannot form an organic coordination between the fan and the duct system. Sometimes, the consistency of the matching position of the axial fan and the guide cover is slightly poor, resulting in a decrease in the air volume, noise and other performance of the fan system. However, in this form, the motor bracket is better stressed, and the force of the fan system is basically not transmitted to the duct system, which will not cause defects such as vibration and deformation of the duct system. For the second form, the fan system and the air duct system are in the form of a component, which can effectively solve the problems of the assembly efficiency of the whole machine and the matching consistency of the fan system and the air duct system. However, the commonly used structural forms are similar to a cantilever beam structure, that is, the motor, fan, and air outlet mesh cover are fixed together, and then the air outlet end of the front cover is directly assembled to the front cover with the air deflector, or the motor, fan, and motor bracket are fixed together, and then the air inlet end of the front cover is directly assembled to the front cover with the air deflector, and then the air outlet mesh cover is directly assembled to the front cover with the air deflector from the air outlet end of the front cover. However, these commonly used structural forms are all unstable structural forms. When the fan is running, the force generated by the fan system will be directly transmitted to the air duct system (i.e., the front cover), which will cause the air duct system (front cover) to vibrate, deform, and other problems. At the same time, in order to reduce the vibration of the air duct system, the fan system is usually fixed by slightly larger bolts, etc., and these bolts will be exposed on the appearance of the product, which will reduce the aesthetics of the product. Especially for the fixing method that fixes the motor, fan, and air outlet mesh together, and then directly assembles the air outlet end of the front cover to the front cover with the air guide cover, in order to firmly fix the fan system, a wire mesh or sheet metal mesh is generally used for the air outlet, and it is difficult to use plastic products, so it will also lead to a decrease in the aesthetics of the product and even cause the deterioration of the product's air outlet wind field performance.

[0003] Therefore, in order to solve the defects brought by the above two methods of fixing the fan duct system, the present application has developed an air conditioner, which adopts the design and matching combination of various fixed structures to transform the current unstable structural form similar to a cantilever beam into a stable structural form similar to a simply supported beam. The force generated by the operation of the fan system can be dispersed from being borne by the front cover alone to being borne jointly by the front cover and the air conditioner base plate, which can solve the shortcomings of the above two conventional methods and can reduce the vibration transmitted to the front cover with the air deflector. In addition, the structure is stable and reliable, the product has high assembly efficiency, and close assembly can be achieved, thereby improving the aesthetics of the product. These are technical problems that need to be solved urgently. Summary of the invention

[0081] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0084] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0086] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0087] The air conditioner of the present invention performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0088] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0089] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0090] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0091] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0092] At present, there are usually two forms of fixed structural forms of the fan duct system of the outdoor unit of the air conditioner: one form is to divide the fan duct system into two parts: one part is the fan system, that is, the axial fan, the motor, and the motor bracket are combined into a component and fixed on the bottom plate of the air conditioner; the other part is the duct system, that is, the air deflector assembly of the air conditioner. The second form is to take the fan duct system as a whole, that is, the air deflector assembly, the axial fan, the motor, and the motor bracket are combined into an independent component. For the first form, the fan system and the duct system are separate components, which is time-consuming and laborious during assembly, and cannot form an organic coordination between the fan system and the duct system. Sometimes, the consistency of the matching position of the axial fan and the air deflector assembly is slightly poor, resulting in a decrease in the air volume, noise and other performance of the fan duct system. However, in this form, the motor bracket is better stressed, and the force of the fan system is basically not transmitted to the duct system, which will not cause defects such as vibration and deformation of the duct system.

[0093] For the second form, the fan system and the duct system are a component form, which can effectively solve the problems of the assembly efficiency of the whole machine and the matching consistency of the fan system and the duct system. However, this form is an unstable structural form. When the fan is running, the force of the fan system will be directly transferred to the duct system, which will cause problems such as vibration of the duct system. At the same time, in order to reduce the vibration of the duct system, the fan system is usually fixed with slightly larger bolts, etc., and these bolts will be exposed on the appearance of the product, which will reduce the appearance of the product. In this fixing method, in order to firmly fix the fan system, a wire mesh or sheet metal mesh is generally used for the air outlet, and it is difficult to use plastic products, so it will also reduce the appearance of the product and even cause the deterioration of the product's wind field performance.

[0094] In order to solve the defects brought by the above two methods of fixing the fan duct system, the present invention patent invents a method of fixing the fan duct system, which realizes a new method of fixing the fan duct system by effectively combining the above two methods through the design and matching combination of various fixing structures. It perfectly solves the shortcomings brought by the above two conventional methods.

[0095] In this embodiment, if Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the air conditioner includes a fan duct system, which includes a shroud assembly 100 , a motor bracket 200 , an axial flow fan 300 and a motor 400 .

[0096] The fixed end of the motor 400 is mounted on the motor bracket 200. The output end of the motor 400 is connected to the axial flow fan 300. The motor 400 is connected to the air guide cover assembly 100 through the motor bracket 200.

[0097] like Figure 3 , Figure 4 As shown, the air duct assembly 100 includes an air duct body 110, an upper attachment 120 extending along an upper edge of the air duct body, and a lower attachment 130 extending along a lower edge of the air duct body.

[0098] like Fig.11 , Fig.12 As shown, the air guide cover body 110 includes a front shell 111 and an air guide ring 112 .

[0099] The front shell 111 is a plate-shaped structure, and the upper attachment 120 is extended along the upper edge of the front shell 111 .

[0100] The lower attachment 130 is extended along the lower edge of the front housing 111 .

[0101] The upper attachment 120 extending along the upper edge and the lower attachment 130 extending along the lower edge can greatly improve the structural strength of the front shell 111.

[0102] Since the connection between the front housing 111 and the motor bracket 200 is a major stress concentration site, the motor bracket 200 is connected to a location of the front housing 111 where the structural strength is relatively high. Therefore, the motor bracket 200 is connected to the upper attachment 120 and the lower attachment 130 .

[0103] In this embodiment, if Fig.12 , Fig.13 As shown, the upper attachment 120 includes a first bent plate, and the lower attachment 130 includes a second bent plate.

[0104] A first accommodating cavity 121 is formed between the first bending plate and the air duct body 110 .

[0105] A second accommodating cavity 131 is formed between the second bending plate and the air duct body 110 .

[0106] A first mounting surface 122 is formed on a side surface of the first bent plate away from the air duct body 110 .

[0107] A second mounting surface 132 is formed on a side surface of the second bent plate away from the air duct body 110 .

[0108] A first bolt connection hole is provided at the corresponding position between the first mounting surface 122 and the upper end of the motor bracket 200, and a second bolt connection hole is provided at the corresponding position between the second mounting surface 132 and the lower end of the motor bracket 200. The first bolt passes through the first bolt connection hole to connect the upper end of the motor bracket 200 with the upper accessory 120, and the second bolt passes through the second bolt connection hole to connect the lower end of the motor bracket 200 with the lower accessory 130.

[0109] Specifically, the upper attachment 120 is formed with an upper attachment boss 123 with a rectangular cross-sectional shape extending in the width direction of the front housing 111 in the middle portion along the vertical direction, and a first through groove with a rectangular cross-sectional shape extending in the length direction of the upper attachment boss 123 is formed in the upper attachment boss 123, which is the first accommodating cavity 121. The upper attachment boss 123 protrudes toward the interior of the air conditioner outdoor unit.

[0110] The first bolt is accommodated in the first accommodation cavity 121 , which improves the aesthetic appearance.

[0111] The first contact surface 124 is formed by bending along the upper edge of the upper attachment boss 123 , and the second contact surface 125 is formed by bending along the lower edge of the upper attachment boss 123 . Both the first contact surface 124 and the second contact surface 125 abut against the front housing 111 .

[0112] In order to install the upper cover 500 of the air conditioner outdoor unit on the front housing 111, a third boss 1111 is formed at the upper edge of the front housing 111, and the protruding direction of the third boss 1111 is toward the inside of the air conditioner outdoor unit.

[0113] The upper surface of the inner surface of the upper attachment boss 123 abuts against the upper surface of the outer surface of the third boss 1111. The upper attachment boss 123 is sleeved outside the third boss 1111, thereby further improving the bending rigidity of the upper housing 111.

[0114] Specifically, a lower accessory boss 133 with a rectangular cross-section extending in the width direction of the front housing 111 is formed in the middle of the lower accessory 130 in the vertical direction, and a second through groove with a rectangular cross-section extending in the length direction of the lower accessory boss 133 is formed in the lower accessory boss 133, which is the second accommodating cavity 131. The protruding direction of the lower accessory boss 133 is toward the inside of the air conditioner outdoor unit.

[0115] The second bolt is accommodated in the second accommodation cavity 131 , which improves the aesthetic appearance.

[0116] A third contact surface 134 is formed by bending along the upper edge of the lower attachment boss 133 , and a fourth contact surface 135 is formed by bending along the lower edge of the lower attachment boss 133 . Both the third contact surface 134 and the fourth contact surface 135 abut against the front housing 111 .

[0117] The upper attachment 120 is extended along the upper edge of the width direction of the front shell 111, and the lower attachment 130 is extended along the lower edge of the width direction of the front shell 111, thereby improving the bending rigidity of the front shell 111 and even the air duct body 110. In addition, the upper attachment 120 can improve the support rigidity of the upper edge of the front shell 111, and the lower attachment 130 can improve the support rigidity of the lower edge of the front shell 111. In addition, both the upper attachment 120 and the lower attachment 130 adopt a bending structure, which can effectively resist and reduce the force transmitted from the motor 400 to the air duct body 110 through the motor bracket 200, thereby greatly reducing the force on the air duct body 110.

[0118] In order to realize the arrangement of two or more fan duct systems in the outdoor unit of the air conditioner, the two or more fan duct systems are superimposed and used to form a stable and reliable structure. In this embodiment, the lower edge of the lower attachment 130 is a fourth contact surface 135, and a snap-on component 136 is provided on the lower edge of the lower attachment 130.

[0119] If another fan duct system is disposed below the lower attachment 130 , the clamping component 136 is clamped with the upper attachment 120 .

[0120] Specifically, the clamping component 136 includes an assembly slot 137 formed by bending a plate and a plurality of assembly bosses 138 spaced apart along the length direction of the assembly slot 137 .

[0121] The assembly slot 137 is extended along the lower edge of the lower attachment 130 .

[0122] like Fig. 9 , Fig.10 As shown, a plurality of assembly bosses 138 are arranged at intervals along the extension direction of the assembly slot 137. When assembled with the adjacent fan duct system, the surface friction between the upper attachment 120 of the adjacent fan duct system and the assembly slot 137 of the adjacent lower attachment 130 located above is changed to line friction, thereby reducing the assembly friction, reducing the assembly difficulty, and ensuring the stability of the assembly. After assembly, the assembly boss 138 forms an interference fit with the mating surface, that is, the first contact surface 124 of the upper attachment 120, which can replace the bolt connection and improve the assembly efficiency.

[0123] At the same time, the above-mentioned clamping component 136 can also be applied to the connection between the lower attachment 130 and the bottom plate 600 of the air conditioner outdoor unit. The bottom plate 600 of the air conditioner outdoor unit is inserted into the assembly slot 137 to achieve rapid assembly of the fan duct assembly and the bottom plate 600 of the air conditioner outdoor unit.

[0124] In this embodiment, if Fig.15 , Fig.16 , Fig.17As shown, the motor bracket 200 has an open end. Specifically, the upper end of the open end of the motor bracket 200 is connected to the upper attachment 120 , and the lower end of the open end of the motor bracket 200 is connected to the lower attachment 130 .

[0125] Specifically, the motor bracket 200 may be a U-shaped bending plate. The U-shaped bending plate includes a vertical section 210 and horizontal sections 220 connected to both ends of the vertical section 210. The upper horizontal section 220 is connected to the upper attachment 120, and the lower horizontal section 220 is connected to the lower attachment 130.

[0126] In this embodiment, in order to ensure the stability of the connection between the horizontal section 220 and the vertical section 210 , a triangular support structure 230 is provided at the corner where the horizontal section 220 and the vertical section 210 are connected.

[0127] Taking into account the requirements of the mold bending process, that is, the folding height at the bend cannot be too high, otherwise it cannot be formed; if the folding height is low, since this bend is subjected to a larger force transmitted from the motor 400, this is a stress concentration and easy-to-break location. A triangular support structure 230 is provided at the bend between the horizontal section 220 and the vertical section 210, which changes the transmission route of the bearing force, reduces the force value at the bend, eliminates the stress concentration at the bend, and avoids the risk of fracture here.

[0128] A stable triangular support structure 230 is formed between the horizontal section 220 and the vertical section 210 to ensure the strength and stability reliability of the bending part of the motor bracket 200, thereby improving the overall stability and strength of the motor bracket 200.

[0129] The upper horizontal section 220 is bent toward the vertical section 210, and the vertical section 210 and the horizontal section 220 are bent toward the horizontal section 220 at their adjacent positions, and the two are bent and butted to form a triangular support structure 230. For the convenience of bending, process holes 231 are provided at the bending positions.

[0130] After the process holes 231 are opened on the triangular support structure 230 , support columns 232 are formed at the edges of the triangular support structure 230 .

[0131] In this embodiment, the force output by the motor 400 will affect the air duct assembly 100 , and the installation method of the motor bracket 200 has a great influence on reducing the force output by the motor 400 and the vibration generated.

[0132] In this embodiment, the motor bracket 200 is vertically arranged, and the motor 400 is installed in the middle of the motor bracket 200 .

[0133] An upper support member 240 is formed at an upper portion of the motor bracket 200 , and a lower support member 250 is formed at a lower portion of the motor bracket 200 .

[0134] The upper support member 240 is used to abut against the lower support member 250 of the motor bracket 200 of the adjacent fan duct assembly located above or the upper cover 500 of the air conditioner outdoor unit.

[0135] like Figure 2 , Figure 8 , Fig.18 As shown, the lower support member 250 is used to abut against the upper support member 240 of the motor bracket 200 of the adjacent fan duct assembly or the bottom plate 600 of the air conditioner outdoor unit located below.

[0136] If a plurality of fan duct assemblies are arranged in the outdoor unit of the air conditioner, the plurality of fan duct assemblies are supported in sequence by the motor bracket 200 in the vertical direction, so that the plurality of motors 400 are arranged on the bottom plate 600 of the outdoor unit of the air conditioner through the motor bracket 200. After assembly, this structure can support the entire fan duct system on the bottom plate 600 of the outdoor unit of the air conditioner, avoiding the suspended assembly of the lower part of the motor bracket 200, so that part of the supporting force required by the fan duct system is transmitted to the bottom plate 600 of the outdoor unit of the air conditioner, thereby further reducing the force generated by the motor 400 on the air guide cover assembly 100.

[0137] In this embodiment, if Figure 2 , Figure 8 , Fig.19 As shown, in order to further reduce the transmission of vibration generated by the motor 400, a buffer portion is further provided.

[0138] The buffer portion includes a rubber support block 710 and a rubber vibration isolation block 720 .

[0139] The rubber support block 710 is installed between the upper cover 500 and the upper support member 240 of the air conditioner outdoor unit.

[0140] The rubber vibration isolating block 720 is installed between the bottom plate 600 and the lower supporting member 250 of the air conditioner outdoor unit, or between the adjacent upper supporting member 240 and the lower supporting member 250 .

[0141] The rubber support block 710 and the rubber vibration isolating block 720 can prevent the transmission of vibration and the generation of noise generated by the motor 400 .

[0142] In this embodiment, an upper ventilation hole 241 is provided on the upper support member 240 , and a lower ventilation hole 251 is provided on the lower support member 250 . The upper ventilation hole 241 and the lower ventilation hole 251 can reduce the ventilation resistance of the upper support member 240 and the lower support member 250 .

[0143] The upper ventilation hole 241 and the lower ventilation hole 251 are bent at their edges to obtain flanges, thereby improving the bending resistance of the upper supporting component 240 and the lower supporting component 250 .

[0144] Thereby, the bending rigidity of the motor bracket 200 is ensured, and the dual-effect function of ventilation is also ensured.

[0145] In this embodiment, an upper bending flange 260 is formed to facilitate the connection between the upper end of the opening end of the motor bracket 200 and the first mounting surface 122 of the upper attachment 120. A lower bending flange 270 is formed to facilitate the connection between the lower end of the opening end of the motor bracket 200 and the second mounting surface 132 of the lower attachment 130.

[0146] The first bolt connection hole is formed on the upper bending flange 260 , and the second bolt connection hole is formed on the lower bending flange 270 .

[0147] As described above, the first bolt passes through the first bolt connection hole to realize the connection between the motor bracket 200 and the upper attachment 120 , and the second bolt passes through the second bolt connection hole to realize the connection between the motor bracket 200 and the lower attachment 130 .

[0148] Specifically, in order to improve the rigidity of the upper bending flange 260, a plurality of first reinforcing ribs 261 are arranged at intervals at the connection between the upper bending flange 260 and the upper horizontal section 220. In order to improve the rigidity of the lower bending flange 270, a plurality of second reinforcing ribs 271 are arranged at intervals at the connection between the lower bending flange 270 and the lower horizontal section 220. Thus, the rigidity of the bending parts of the upper bending flange 260 and the lower bending flange 270 is improved.

[0149] In this embodiment, a first assembly elongated hole 242 is formed on the upper supporting member 240 , and an assembly tongue 252 is formed on the lower supporting member 250 .

[0150] If multiple fan duct systems are arranged in sequence along the vertical direction, the assembly tongue 252 on the lower support component 250 of the fan duct system located at the top is inserted into the first assembly long hole 242 opened on the upper support component 240 of the fan duct system located at the bottom. The first assembly long hole 242 can limit the movement range of the assembly tongue 252, thereby suppressing the large displacement of the fan duct system and avoiding the shaking and displacement of the fan duct system.

[0151] A second long assembly hole 610 is formed on the bottom plate 600 of the outdoor unit of the air conditioner, and the assembly tongue 252 on the lower support portion 250 of the fan duct system at the bottom is inserted into the second long assembly hole 610 .

[0152] In this embodiment, both the rubber support block 710 and the rubber vibration isolation block 720 are provided with an assembly buckle 730. The assembly buckle 730 is a column. The two opposite sides of the column are formed with process cut corners, and the center of the column is formed with a process hole.

[0153] In this embodiment, the upper support member 240 is provided with first circular assembly holes, specifically, the number of the first circular assembly holes is two. The lower support member 250 is provided with second circular assembly holes, specifically, the number of the second circular assembly holes is two.

[0154] The assembly buckles 730 disposed on the rubber support block 710 are disposed downward and installed in the first assembly circular holes. The number of the assembly buckles 730 disposed on the rubber support block 710 is the same as the number of the first assembly circular holes.

[0155] The assembly buckles 730 disposed on the rubber vibration isolation block 720 are disposed upward and installed in the second assembly circular holes. The number of the assembly buckles 730 disposed on the rubber vibration isolation block 720 is the same as the number of the second assembly circular holes.

[0156] Since the assembly buckle 730 has process cut corners on its two opposite sides, during the process of being installed into the first assembly circular hole or the second assembly circular hole, the two sides of the assembly buckle 730 with the process cut corners are subjected to extrusion force toward the center, thereby causing inward deformation, and the two sides of the assembly opening 730 without the process cut corners are deformed outward, thereby facilitating installation into the first assembly circular hole or the second assembly circular hole.

[0157] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0158] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
