The embodiments described below are exemplary in nature and are intended to be illustrative of the present application rather than to limit the present application. Below, embodiments of the present application are described in detail with reference to the attached drawings.

[0043] The disclosure that follows provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of the various examples are described in terms of specific embodiments. Of course, they are merely examples and are not intended to limit the present application. Furthermore, the present application can be implemented in a variety of environments and / or settings. Like numbers refer to like elements throughout the several views. Additionally, the present application contemplates that the elements and / or devices described herein can also be implemented in a computer-aided design (CAD) environment.

[0044] Below, with reference to the drawings, an air conditioner 100 according to an embodiment of the present application is described.

[0045] As Figure 1 and Figure 2As shown, the air conditioner 100 can include a housing component 1, a heat exchange component 2, and a ventilation component 3, the front side of the housing component 1 is formed with an air outlet 15, the left side and / or the right side of the housing component 1 is formed with an air inlet 16, in combination Figures 3-5 The heat exchange component 2 is arranged in the housing component 1 and includes a heat exchanger 21 and an electric auxiliary heater 22, the heat exchanger 21 extends forwardly and downwardly in an inclined manner, the heat exchanger 21 is in a rear convex form to form a concave space at the front side, that is, the heat exchanger 21 is convex rearwardly from the left and right sides to the center, so that the front side of the heat exchanger 21 forms a concave space opposite to the rear convex position, for example, the heat exchanger 21 can be a U-shaped heat exchanger 21 or a V-shaped heat exchanger 21, etc., the electric auxiliary heater 22 is arranged in the housing component 1 and located in the concave space at the front side of the heat exchanger 21.

[0046] As shown in Figure 2 , Figure 3 and Figure 6 , the thickness of the heat exchanger 21 is divided into a windward side 211 and a leeward side 212, the windward side 211 is arranged close to the rear side of the housing component 1 relative to the leeward side 212, the ventilation component 3 is arranged in the housing component 1 and below the heat exchanger 21, the ventilation component 3 includes a centrifugal fan and sucks air from the air inlet 16 (for example, in the direction indicated by the arrow A shown in Figure 2 ) and sends air to the windward side 211 of the heat exchanger 21 (for example, in the direction indicated by the arrow B shown in Figure 3 ), the air flow passes from the windward side 211 of the heat exchanger 21 to the leeward side 212 of the heat exchanger 21 (for example, in the direction indicated by the arrow C shown in Figure 3 and Figure 6 ), the air flow passing from the windward side 211 of the heat exchanger 21 to the leeward side 212 of the heat exchanger 21 is sent out through the air outlet 15 (for example, in the direction indicated by the arrow D shown in Figure 3 ).

[0047] In related technologies, front-discharge air conditioning units typically use flat-plate heat exchangers, usually arranged in three rows. These heat exchangers have a small frontal area, high air resistance, high noise, and low heat exchange efficiency. However, the air conditioner 100 according to this embodiment of the invention, by setting the heat exchanger 21 to an inclined and rearward-convex form, can effectively increase the frontal area, improve heat exchange efficiency, and reduce the number of rows. For example, two rows can be accommodated in the same space, thereby saving material costs for the heat exchanger 21, reducing its air resistance, and lowering the operating noise of the air conditioner 100. Furthermore, because the heat exchanger 21 is rearward-convex, the electric auxiliary heater 22 can be housed in the recessed space on its front side, improving the overall structural compactness. Additionally, since the ventilation component 3 includes a centrifugal fan and is located below the heat exchange component 2, the rearward-convex heat exchanger 21 can effectively reduce the overall thickness of the air conditioner 100 in the front-to-back direction, while also increasing the overall airflow. Furthermore, by installing a centrifugal fan, the air inlet 16 can be located on the left and right sides of the housing component 1, rather than on the rear side of the housing, allowing the rear side of the housing component 1 to be installed against the wall, thus saving indoor space. In addition, since the heat exchanger 21 is designed to extend forward at an angle from top to bottom, while increasing the heat exchange area, it can also increase the space for the ventilation component 3 to deliver air to the windward side 211 of the heat exchanger 21, thereby effectively reducing wind resistance and noise.

[0048] It should be noted that the tilt angle of the heat exchanger 21 is not limited; for example, in some embodiments of the present invention, such as... Figure 3 As shown, the inclination angle of the heat exchanger 21 extending forward from top to bottom is 5°-25°, that is, the angle α between the rear surface of the heat exchanger 21 and the vertical plane can be 5°-25°, for example, 5°, 10°, 15°, 20°, 25°, etc. This allows for a better balance between increasing the heat exchange area and simultaneously increasing the space for the ventilation component 3 to supply air to the windward side 211 of the heat exchanger 21, thereby effectively reducing wind resistance and noise.

[0049] Optionally, the inclination angle of the heat exchanger 21 extending forward from top to bottom is 10°-20°, that is, the angle α between the rear surface of the heat exchanger 21 and the vertical plane can be 10°-20°, for example, 10°, 12°, 14°, 16°, 18°, 20°, etc. This better balances increasing the heat exchange area while simultaneously increasing the space for the ventilation component 3 to supply air to the windward side 211 of the heat exchanger 21, thereby effectively reducing wind resistance and noise.

[0050] In some embodiments of the present invention, such as Figure 2As shown, the heat exchange component 2 further comprises a mounting bracket 23, which is arranged in and mounted to the housing component 1, and the left and right sides of the heat exchanger 21 are respectively mounted to the mounting bracket 23. Thus, by arranging the mounting bracket 23, compared with directly mounting the heat exchanger 21 to the housing component 1, the structure of the housing component 1 and the air duct sealing and the like can be simplified, so that the installation difficulty of the heat exchanger 21 can be reduced, and the installation efficiency of the heat exchanger 21 can be improved. For example, in combination with Figure 3 and Figure 6 The air inlet cavity 17 located at the windward side 211 of the heat exchanger 21 can be defined by the mounting bracket 23 and the heat exchanger 21, or by the mounting bracket 23, the heat exchanger 21 and the housing component 1, or by the mounting bracket 23, the heat exchanger 21, the housing component 1 and the ventilation component 3. For example, the air outlet cavity 18 located at the leeward side 212 of the heat exchanger 21 can be defined by the mounting bracket 23, the heat exchanger 21 and the front cover plate 5, or by the mounting bracket 23, the heat exchanger 21 and the housing component 1. The ventilation component 3 sends air to the air inlet cavity 17, and the air outlet cavity 18 discharges air through the air outlet 15.

[0051] In some embodiments of the present application, as shown in Figure 7 and Figure 8 The mounting bracket 23 comprises a flow guide plate 231 and a water pan 232, the flow guide plate 231 is arranged at the bottom of the heat exchanger 21, and the water pan 232 is arranged at the bottom of the flow guide plate 231, wherein the cross-sectional shape of the upper end of the flow guide plate 231 matches the cross-sectional shape of the lower end of the heat exchanger 21, i.e. the same or substantially the same shape, and the same or close size. Thus, since the mounting bracket 23 integrates the flow guide plate 231 and the water pan 232, the condensed water condensed on the heat exchanger 21 can directly drip into the water pan 232, or flow downward along the heat exchanger 21 to the flow guide plate 231, and then enter the water pan 232, thereby achieving the effect of recovering condensed water and improving the reliability of the air conditioner 100. Moreover, since the water pan 232 and the flow guide plate 231 are integrated on the mounting bracket 23, the structural compactness can be improved, and the water pan 232 and the like need not be additionally arranged in the housing component 1, thereby simplifying the structure and the production process.

[0052] In some embodiments of the present application, as shown in Figure 7 and Figure 8 The flow guide plate 231 curves from top to bottom and forward along a curve, and is smoothly and transitionally connected to the rear end of the water pan 232. Thus, the airflow blown by the ventilation component 3 from below to above towards the air inlet side of the heat exchanger 21 can be guided by the curved surface of the flow guide plate 231, thereby reducing the air resistance.

[0053] In some embodiments of the present application, as shown in Figure 7As shown, the mounting bracket 23 is an integral piece and further comprises an upper end plate 233 at the top of the heat exchanger 21 and two side plates 234 at the left and right sides of the heat exchanger 21, which are combined with Figure 4 and Figure 5 As shown, the left and right sides of the heat exchanger 21 are respectively provided with a side plate 213, which is connected with the rear end of the corresponding side plate 234. As shown, Figure 7 The mounting bracket 23 comprises a mounting plate 235 provided at the front end of each side plate 234, and the flow guide plate 231 and the water pan 232 are respectively connected at the lower end of the rear side of the two mounting plates 235, and the mounting plate 235 is connected to the shell component 1. Thus, the mounting bracket 23 has a simple structure, is easy to connect with the heat exchanger 21 and the shell component 1, and the connection of the heat exchanger 21 and the shell component 1 does not interfere with each other, is easy to operate, and the mounting bracket 23 with the above structure is easy to cooperate with the heat exchanger 21 and the like to jointly define the air outlet cavity 18. In addition, since the mounting bracket 23 is an integral piece, it has a simple structure, is easy to process, and has good structural reliability, and simplifies the assembly process.

[0054] In some embodiments of the present application, as shown in Figure 4 and Figure 5 The upper and lower ends of the electric auxiliary heater 22 are respectively mounted on the mounting bracket 23. For example, the electric auxiliary heater 22 comprises a body part 221 and an upper mounting part 222 and a lower mounting part 223 respectively provided at the upper and lower ends of the body part 221, i.e. the upper mounting part 222 is provided at the upper end of the body part 221, and the lower mounting part 223 is provided at the lower end of the body part 221, and the upper mounting part 222 and the lower mounting part 223 are respectively mounted on the mounting bracket 23. Thus, the mounting bracket 23 has powerful functions, and can integrate the mounting bracket 23, the electric auxiliary heater 22 and the heat exchanger 21 into one component, which is jointly mounted on the shell component 1, realizing modular assembly, which reduces the assembly difficulty and improves the assembly efficiency compared with mounting each component on the shell component 1 respectively.

[0055] When the upper and lower ends of the electric auxiliary heater 22 are respectively mounted on the mounting bracket 23, optionally, as shown in Figure 4 and Figure 5As shown, the mounting bracket 23 can include an upper end plate 233 located above the heat exchanger 21 and a water pan 232 located below the heat exchanger 21, the upper end plate 233 is formed with an upper mounting seat 2331, the water pan 232 is provided with a lower mounting seat 2322, the electric auxiliary heater 22 includes a body part 221, an upper mounting part 222 and a lower mounting part 223, the upper mounting part 222 is mounted on the upper mounting seat 2331, and the lower mounting part 223 is mounted on the lower mounting seat 2322. In this way, the top sealing can be formed by using the upper end plate 233, so as to avoid the airflow flowing from the top of the heat exchanger 21 without being heated by the heat exchanger 21, and to ensure the heat exchange reliability, and meanwhile, the water pan 232 can be used to collect the condensed water dropped from the heat exchanger 21 and the electric auxiliary heater 22, so as to avoid the condensed water affecting the work of other components. Since the mounting bracket 23 is integrated with the upper end plate 233 and the water pan 232, compared with the case that a separate upper sealing plate and a lower water collecting device are arranged inside the shell part 1, the structure compactness can be improved, the structure can be simplified, the assembly can be simplified, and the cost can be reduced. Meanwhile, by arranging the upper mounting seat 2331 on the upper end plate 233 located above the heat exchanger 21 and arranging the lower mounting seat 2322 in the water pan 232 located below the heat exchanger 21, the upper and lower ends of the electric auxiliary heater 22 can be mounted, so as to reduce the influence of the mounting structure on the ventilation of the heat exchanger 21 as much as possible, and to improve the heat exchange reliability.

[0056] In some optional examples, as shown in Figures 4-5 and Figure 7 , the upper mounting seat 2331 can protrude upwardly from the upper end plate 233, and the upper end of the body part 221 is flush with or protrudes upwardly beyond the upper end of the heat exchanger 21. In this way, the upper and lower heat exchange temperature differences can be reduced, and the consistency of the heat exchange temperature can be improved. Moreover, the influence of the upper mounting seat 2331 on the ventilation of the heat exchanger 21 can be reduced as much as possible, and the heat exchange reliability can be improved. In some optional examples, as shown in Figures 4-5 and Figure 7 , the lower end of the body part 221 is flush with or protrudes downwardly beyond the lower end of the heat exchanger 21. In this way, the upper and lower heat exchange temperature differences can be reduced, and the consistency of the heat exchange temperature can be improved. Moreover, the influence of the lower mounting seat 2322 on the ventilation of the heat exchanger 21 can be reduced as much as possible, and the heat exchange reliability can be improved.

[0057] In addition, it should be noted that when the upper and lower ends of the electric auxiliary heater 22 are respectively mounted on the mounting bracket 23, in some embodiments of the present application, the mounting bracket 23 can also be configured as an integral piece including the mounting plate 235, the side plate 234 and the flow guide plate 231, and the technical effects can be referred to the above description, which will not be repeated here.

[0058] In some embodiments of the present application, as shown in Figure 2 and Figure 3 , and in combination with Figure 9 and Figure 10The air conditioner 100 can further comprise a front cover plate 5 located at the front side of the heat exchanger 21 and connected to the mounting bracket 23, so that the heat exchanger 21, the mounting bracket 23 and the front cover plate 5 form an air outlet cavity 18, and the front cover plate 5 is provided with an air vent 51 opposite the air outlet 15. Thus, by providing the front cover plate 5, the air duct sealing can be simplified, the structure can be simplified, and the assembly efficiency can be improved.

[0059] In some embodiments of the present application, as shown in Figures 1-3 , the shell component 1 can comprise a rear box 11 and a front panel 12, the heat exchange component 2 is arranged in the rear box 11, the front panel 12 is arranged at the front side of the rear box 11, at least a part of the mounting bracket 23 used to define the air outlet cavity 18 forms a first gap 25 with the rear box 11, at least a part of the front cover plate 5 used to define the air outlet cavity 18 forms a second gap 26 with the front panel 12, and in combination Figure 11 and Figure 12 , at least one of the first gap 25 and the second gap 26 is filled with a filler 4. It should be noted that the material of the filler 4 is not limited, as long as it can at least one of the effects of heat preservation and noise reduction, for example, it can be a foam piece, a sponge piece, etc. Thus, the heat preservation effect can be improved, the probability of condensation on the shell component 1 can be reduced, and / or the noise reduction effect can be achieved to some extent.

[0060] For example, as shown in Figures 2-3 , Figures 5-6 , the rear box 11 can comprise a top cover 111, a base 112 and two side walls 113, the left and right side plates 234 of the mounting bracket 23 form a first gap 25 with the side walls 113 corresponding to the left and right sides of the rear box 11, in combination Figure 12 , the first gap 25 is filled with the filler 4, the upper end plate 233 of the mounting bracket 23 forms a first gap 25 with the top cover 111 of the rear box 11, in combination Figure 11 , the first gap 25 is also filled with the filler 4, the front cover plate 5 forms a second gap 26 with the front panel 12, in combination Figure 11 , the second gap 26 is also filled with the filler 4. Thus, the heat preservation effect can be improved, the probability of condensation on the shell component 1 can be reduced, and / or the noise reduction effect can be achieved to some extent.

[0061] In some embodiments of the present application, as shown in Figure 13 and Figure 14As shown, at least the part of the mounting bracket 23 used to define the air outlet cavity 18 is formed with first noise reduction holes 236, whereby the working noise of the air conditioner 100 can be reduced and the use comfort can be improved. It is worth mentioning that in order to achieve the noise reduction effect and avoid air leakage, the first noise reduction holes 236 can be micro-holes and the hole diameter can be set according to actual conditions, for example, can be no more than 3mm, such as about 2mm. For example, when the mounting bracket 23 includes the upper end plate 233 and the two side plates 234, the first noise reduction holes 236 can be formed on the two side plates 234 and the upper end plate 233 respectively, so that the noise can be better reduced.

[0062] Further, when the first gap 25 is filled with the filler 4, at least the part of the mounting bracket 23 used to define the air outlet cavity 18 is formed with first noise reduction holes 236, whereby the working noise of the air conditioner 100 can be reduced and the use comfort can be improved, and the resistance of the filler 4 can be used to reduce the probability of air leakage of the air outlet cavity 18 through the first noise reduction holes 236.

[0063] In some embodiments of the present application, as shown in Figure 13 and Figure 14 As shown, at least the part of the front cover plate 5 used to define the air outlet cavity 18 is formed with second noise reduction holes 52, whereby the working noise of the air conditioner 100 can be reduced and the use comfort can be improved. It is worth mentioning that in order to achieve the noise reduction effect and avoid air leakage, the second noise reduction holes 52 can be micro-holes and the hole diameter can be set according to actual conditions, for example, can be no more than 3mm, such as about 2mm.

[0064] Further, when the second gap 26 is filled with the filler 4, at least the part of the front cover plate 5 used to define the air outlet cavity 18 is formed with second noise reduction holes 52, whereby the working noise of the air conditioner 100 can be reduced and the use comfort can be improved, and the resistance of the filler 4 can be used to reduce the probability of air leakage of the air outlet cavity 18 through the second noise reduction holes 52.

[0065] Thus, by setting the filler 4 and the multiple preventive measures of the first noise reduction holes 236 and the second noise reduction holes 52, the risk of condensation and noise outside the machine body is reduced. Alternatively, the filler 4 can be a loose material, that is, with pores and the like, so as to further reduce the operating noise of the whole machine.

[0073] As described above, the air conditioner 100 of the above embodiment can be a split floor standing air conditioner 100 or a wall-mounted cabinet machine, the shell part 1 of which comprises a rear cabinet 11 and a front panel 12, the shell part 1 is provided with a heat exchange part 2 and a ventilation part 3, the heat exchanger 21 in the heat exchange part 2 is installed in the rear cabinet 11 and located at the upper part or the middle and upper part of the whole machine, the ventilation part 3 is also installed in the rear cabinet 11 and located below the heat exchange part 2, the left and right sides of the ventilation part 3 are respectively provided with air duct inlets corresponding to the air inlets 16 on the left and right sides of the rear cabinet 11, so that when the double-suction centrifugal fan in the ventilation part 3 works, the air duct inlets on each side can suck air from the outside of the shell through the corresponding air inlet 16, and the air inlets 16 of the rear cabinet 11 can be provided with air inlet grilles, so as to improve the sealing performance of the shell part 1 and the safety of the air conditioner 100. The front panel 12 is installed on the front side of the rear cabinet 11, and the upper part of the front panel 12 is provided with an air outlet 15, and a guide mechanism can be arranged at the position corresponding to the air outlet 15. The air after being heat exchanged by the heat exchange part 2 can change the direction of the wind through the guide mechanism and be blown into the room through the air outlet 15. The top of the rear cabinet 11 is provided with a top cover 111 for sealing the top of the whole machine, and the bottom of the rear cabinet 11 is provided with a base 112 for supporting the rear cabinet 11, so as to support the heat exchange part 2, the ventilation part 3, the front panel 12 and the guide mechanism installed on the rear cabinet 11.

[0074] The heat exchanger 21 in the heat exchange part 2 can be a curved or broken line shape, and can be an integral structure or a split splicing structure. The heat exchanger 21 is installed at an inclination on the installation bracket 23 of the heat exchange part 2, and the inclination angle thereof can be in the range of 5°-25°, for example, 5°, 10°, 15°, 20°, 25°, etc. For example, it can be specifically selected as 10°-20°, for example, 10°, 12°, 14°, 16°, 18°, 20°, etc. In this way, the above-mentioned increase in heat exchange area can be better considered, and at the same time, the space for the ventilation part 3 to send air to the windward side 211 of the heat exchanger 21 can be increased, so that the effect of effectively reducing the wind resistance and noise can be achieved.

[0075] The mounting bracket 23 consists of a left side plate 234, a right side plate 234, an upper end plate 233, a guide plate 231, a water receiving tray 232, and left and right mounting plates 235. The left side plate 213 of the heat exchanger 21 is connected to the left mounting plate 235 of the mounting bracket 23, and the right side plate 213 of the heat exchanger 21 is connected to the right mounting plate 235 of the mounting bracket 23. The mounting bracket 23 is a one-piece molded part, and the mounting bracket 23 and the heat exchanger 21 form a relatively sealed structure in four directions, separating the airflow passing through the heat exchanger 21 from the airflow that does not pass through the heat exchanger 21. The electric auxiliary heater 22 is also fixed on the mounting bracket 23. The electric auxiliary heater 22 is located in the recessed space in front of the heat exchanger 21. The lower end of the electric auxiliary heater 22 is fixed to the lower mounting seat 2322 at the bottom of the mounting bracket 23, and the upper end is inserted into the upper mounting seat 2331 on the upper end plate 233.

[0076] The lower part of the mounting bracket 23 has a guide plate 231 located below the heat exchanger 21. The shape and size of the guide plate 231 are adapted to the shape and size of the lower end of the heat exchanger 21. The water receiving tray 232 of the mounting bracket 23 is located at the lower end of the guide plate 231 and receives the condensate flowing down from the heat exchanger 21 and the guide plate 231. The bottom of the water receiving tray 232 has a drain outlet 2321, which is connected to a drain pipe to discharge the condensate to the outside of the air conditioner 100. The connection between the guide plate 231 and the water receiving tray 232 has a large chamfer, which makes the airflow blowing upward by the ventilation component 3 smoother and reduces wind resistance.

[0077] The mounting bracket 23 is connected to the front ends of the left and right sides of the rear housing 11 via two mounting plates 235, thus fixing the heat exchange component 2 to the rear housing 11 as a whole. A front cover plate 5 is provided between the mounting bracket 23 and the front panel 12. The front cover plate 5 is sealed to the periphery of the mounting bracket 23. A vent 51 is provided on the front cover plate 5 corresponding to the air outlet 15, so that the front cover plate 5, the heat exchanger 21, and the mounting bracket 23 together define a relatively enclosed space except for the vent 51, that is, forming the air outlet cavity 18. The heat exchange component 2, the rear housing 11, and the ventilation component 3 also together define a relatively enclosed space, that is, forming the air inlet cavity 17.

[0078] There are gaps between the mounting bracket 23 and the top cover 111 of the rear housing 11, between the mounting bracket 23 and the side wall 113 of the rear housing 11, and between the front cover 5 and the front panel 12. Filling these gaps with filler 4, such as a loose material, can reduce the risk of condensation on the outer surface of the housing component 1 and also reduce the transmission of noise generated in the air outlet cavity 18 to the outside of the housing component 1, thus achieving a good noise reduction effect. Furthermore, noise reduction holes can be made on both sides and the top of the mounting bracket 23, and noise reduction holes can also be made on the front cover 5, thereby further reducing the operating noise of the air conditioner 100.

[0079] The air conditioner 100 according to the embodiment of the present application, by setting the heat exchanger 21 to be inclined and convex at the back, can effectively increase the windward area, improve the heat exchange efficiency, and reduce the number of rows, for example, two rows can be accommodated in the same space, thereby saving the material cost of the heat exchanger 21, reducing the wind resistance of the heat exchanger 21, and reducing the operating noise of the air conditioner 100. Moreover, since the heat exchanger 21 is in the form of convex at the back, the electric auxiliary heater 22 can be accommodated in the concave space in front of the heat exchanger 21, improving the overall structural compactness. In addition, since the ventilation component 3 includes a centrifugal fan and is located below the heat exchange component 2, for the heat exchanger 21 in the form of convex at the back, the thickness of the air conditioner 100 in the front-rear direction can be effectively reduced, and the air volume of the whole machine can be improved. Moreover, by setting the centrifugal fan, the air inlet 16 can be located on the left and right sides of the shell component 1, rather than on the back side of the shell, so that the back side of the shell component 1 can be arranged against the wall, thereby saving indoor space. In addition, since the heat exchanger 21 is set to extend forward from top to bottom, the space for the ventilation component 3 to send air to the windward side 211 of the heat exchanger 21 can be increased while increasing the heat exchange area, thereby effectively reducing the wind resistance and noise. Moreover, through the multiple preventive measures of the filler 4 and the noise reduction hole, the risk of condensation outside the machine body is reduced.
