For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0048] like Figure 4 As shown, the air conditioner 100 according to the embodiment of the present utility model includes a heat exchanger assembly 10 , an auxiliary heater 3 and an air duct assembly 20 .

[0049] Specifically, refer to the attached Figure 4 and attached Figure 5As shown, the heat exchanger assembly 10 includes a bracket 1 and a heat exchanger 2. The bracket 1 includes a body 11, a top cover 12 and a bottom plate 13. The top cover 12 and the bottom plate 13 are respectively arranged in the length direction of the body 11 (refer to the attached Figure 5 The heat exchanger 2 is located in the installation space 14 and is arranged on the side of the main body 11 facing the installation space 14. The heat exchanger 2 serves as the main heat source device of the air conditioner 100 and can efficiently transfer heat to meet the user's heating needs.

[0050] It can be understood that the bracket 1 is used to install and support the heat exchanger 2, and can firmly install and fix the heat exchanger 2 in the air conditioner 100. The design of the bracket 1 often takes into account the overall layout and weight distribution of the heat exchanger 2, and can adopt a reasonable structural form to enhance the supporting effect of the heat exchanger 2 and reduce stress concentration.

[0051] Further, see Attachment Figure 5 As shown, the auxiliary heater 3 is located in the installation space 14 and on the side of the heat exchanger 2 away from the main body 11. The auxiliary heater 3, as an auxiliary heat source device of the air conditioner 100, can use electric current to pass through the heating element to generate heat, and then heat the surrounding airflow, thereby preventing the heating capacity and heating performance coefficient of the main heat source device (heat exchanger 2) from decreasing, and ensuring the heating capacity of the air conditioner 100.

[0052] Further, see Appendix Figure 5 As shown, the auxiliary heater 3 has a length direction (see attached Figure 5 The two ends of the auxiliary heater 3 (in the up and down direction shown in the figure) are respectively a first end 31 and a second end 32, the first end 31 is fixed to the top cover 12, the second end 32 and the chassis 13 are connected by a fastener 15, and a first positioning structure 33 is provided on the second end 32, and a second positioning structure 16 cooperating with the first positioning structure 33 is provided on the chassis 13. It can be understood that before the second end 32 and the chassis 13 are connected by the fastener 15, the cooperation between the first positioning structure 33 and the second positioning structure 16 can play a pre-positioning role on the second end 32 of the auxiliary heater 3, so that the fastener 15 is tightened. The second end 32 and the chassis 13 are fixed, and when the fastener 15 becomes loose, the first positioning structure 33 and the second positioning structure 16 can play a positioning role to ensure the connection between the second end 32 of the auxiliary heater 3 and the chassis 13, and prevent the auxiliary heater 3 from being separated from the bracket 1. At the same time, once the air conditioner 100 collides and falls, the auxiliary heater 3 and the bracket 1 have multiple matching points to disperse the pressure, further preventing the auxiliary heater 3 from falling off the bracket 1, thereby greatly increasing the reliability of the installation of the auxiliary heater 3 and ensuring the stability and reliability of the air conditioner 100.

[0053] It can be understood that when the auxiliary heater 3 is assembled to the bracket 1, the first end 31 is first fixed to the top cover 12, and then the first positioning structure 33 is matched with the second positioning structure 16, and finally the second end 32 is connected to the chassis 13 using the fastener 15, and the two ends of the auxiliary heater 3 in the length direction are respectively fixed to the top cover 12 and the chassis 13 of the bracket 1 to ensure the installation reliability and stability of the auxiliary heater 3.

[0054] It should be noted that the second end 32 and the chassis 13 are connected by a fastener 15, which is convenient for assembly and disassembly, and facilitates the assembly and disassembly of the auxiliary heater 3, reduces the assembly difficulty of the air conditioner 100, and ensures the connection reliability between the auxiliary heater 3 and the bracket 1. For example, the fastener 15 can be a screw.

[0055] Further, see the attached Figure 2 and attached Figure 3 As shown, the air duct assembly 20 can drive the airflow outside the air conditioner 100 into the shell 30. Along the airflow direction, the air duct assembly 20 is located downstream of the heat exchanger assembly 10, which is convenient for the air duct assembly 20 to drive the airflow outside the air conditioner 100 into the shell 30, so that the airflow in the air conditioner 100 first exchanges heat with the heat exchanger assembly 10, and then is blown out of the air conditioner 100 under the drive of the air duct assembly 20, ensuring the heat exchange between the airflow and the heat exchanger assembly 10, ensuring the heating performance and cooling performance of the air conditioner 100, and improving the user experience.

[0056] Further, see Attachment Fig.13 , Attachment Fig.14 and attached Fig.15 As shown, the side of the air duct assembly 20 facing the heat exchanger assembly 10 has a protrusion 201, the protrusion 201 is arranged opposite to the bottom plate 13, the auxiliary heater 3 is located between the protrusion 201 and the bottom plate 13 and is against the protrusion 201 and the bottom plate 13, along the arrangement direction of the heat exchanger assembly 10 and the air duct assembly 20 (refer to the attached Figure 2 The two opposite outer walls of the auxiliary heater 3 are respectively abutted against the inner wall of the recessed portion 132 and the upstream side of the protruding portion 201, and the bracket 1 and the air duct assembly 20 jointly limit the auxiliary heater 3, thereby limiting the degree of freedom of the auxiliary heater 3 in the arrangement direction of the heat exchanger assembly 10 and the air duct assembly 20, preventing the fastener 15 from loosening and affecting the installation of the auxiliary heater 3, and preventing the auxiliary heater 3 from being out of the installation position, thereby further ensuring the installation reliability and stability of the auxiliary heater 3.

[0057] According to the air conditioner 100 of the embodiment of the utility model, the auxiliary heater 3 is located between the protrusion 201 and the chassis 13 and is against the protrusion 201 and the chassis 13. The two ends of the auxiliary heater 3 in the length direction are respectively a first end 31 and a second end 32. The first end 31 is fixed on the top cover 12, and the second end 32 and the chassis 13 are connected by a fastener 15. A first positioning structure 33 is provided on the second end 32, and a second positioning structure 16 cooperating with the first positioning structure 33 is provided on the chassis 13, which can pre-position and limit the auxiliary heater 3, prevent the fastener 15 from loosening and affecting the installation of the auxiliary heater 3, and prevent the auxiliary heater 3 from being out of the installation position, thereby further ensuring the installation reliability and stability of the auxiliary heater 3.

[0058] In some embodiments of the present invention, refer to the attached Figure 7 As shown, the extension direction of the fastener 15 (see attached Figure 7 The front-to-back direction shown in FIG. 1 and the length direction of the bracket 1 (see FIG. Figure 7 The fastener 15 is perpendicular to the vertical direction shown in the figure, so that the fastener 15 is arranged along the direction of the heat exchanger 2 and the auxiliary heater 3 (refer to the attached figure). Figure 7 The auxiliary heater 3 is installed in the front-to-back direction as shown in the figure to fix the auxiliary heater 3 on the bracket 1. Compared with the prior art of installing the locking screws from top to bottom, the installer's hands and installation tools can be kept farther away from the heating fins of the auxiliary heater 3 or the heat dissipation fins of the heat exchanger 2, thereby reducing the probability of the heating fins of the auxiliary heater 3 or the heat dissipation fins of the heat exchanger 2 scratching the installer's limbs and reducing the probability of the heating fins of the auxiliary heater 3 or the heat dissipation fins of the heat exchanger 2 themselves being scratched and damaged, thereby ensuring the reliability and stability of the heat exchanger 2 and the auxiliary heater 3 and extending the service life of the air conditioner 100.

[0059] Preferably, refer to the attached Figure 7 As shown, the fastener 15 is installed from the back to the front, so that the installer's hands and installation tools can be as far away from the heating fins of the auxiliary heater 3 or the heat dissipation fins of the heat exchanger 2 as possible, further reducing the probability of scratching and damaging the heating fins of the auxiliary heater 3 or the heat dissipation fins of the heat exchanger 2. Of course, the utility model is not limited to this. The extension direction of the fastener 15 is parallel to the width direction of the bracket 1 (see attached Figure 7 There may be a certain angle between the left and right directions (as shown).

[0060] In a further embodiment of the present invention, refer to the attached Figure 6As shown, the second end 32 and the chassis 13 are connected by a fastener 15. Compared with the prior art in which the lower end of the auxiliary heater is fixed by two screws, the utility model can reduce the number of fasteners 15 used on the basis of ensuring the connection reliability between the auxiliary heater 3 and the bracket 1, thereby reducing the difficulty of assembling the auxiliary heater 3 and improving the assembly efficiency of the auxiliary heater 3 due to the presence of the first positioning structure 33 and the second positioning structure 16.

[0061] In some embodiments of the present invention, refer to the attached Figure 6 and attached Figure 7 As shown, the first positioning structure 33 includes a first mounting plate 331, the first mounting plate 331 is connected to the chassis 13 by a fastener 15, and the second positioning structure 16 includes a first limiting plate 161, the free end of the first mounting plate 331 abuts against the first limiting plate 161, and is used to position the first mounting plate 331 in the width direction of the bracket 1 (see attached Figure 7 The auxiliary heater 3 is limited in the left and right directions (as shown in the figure), the first mounting plate 331 and the first limiting plate 161 can pre-position the auxiliary heater 3 and ensure that the fastener 15 fixes the first mounting plate 331 on the chassis 13. The free end of the first mounting plate 331 abuts against the first limiting plate 161, which can prevent the auxiliary heater 3 from moving in the direction close to the first limiting plate 161, thereby limiting the auxiliary heater 3 in the width direction of the bracket 1, and can limit the auxiliary heater 3 when the fastener 15 becomes loose to prevent the auxiliary heater 3 from detaching from the bracket 1, thereby improving the reliability of the installation of the auxiliary heater 3 and ensuring the stability and reliability of the air conditioner 100.

[0062] In a further embodiment of the present invention, refer to the attached Figure 7 , Attachment Fig.11 and attached Fig.12 As shown, a mounting column 131 is provided on the chassis 13, and a first mounting plate 331 is fixed to the mounting column 131 by a fastener 15. The second positioning structure 16 also includes a second limiting plate 162, and the second limiting plate 162 is located on the side of the mounting column 131 facing the top cover 12. The first positioning structure 33 also includes an insert plate 332, and the insert plate 332 is inserted between the mounting column 131 and the second limiting plate 162. The cooperation between the insert plate 332 and the mounting column 131 and the second limiting plate 162 can limit the movement of the auxiliary heater 3 in the length direction, and can limit the auxiliary heater 3 when the fastener 15 becomes loose, so as to prevent the auxiliary heater 3 from being separated from the bracket 1, thereby improving the reliability of the installation of the auxiliary heater 3 and ensuring the stability and reliability of the air conditioner 100.

[0063] It should be noted that the reference Figure 7As shown, the plug plate 332 is connected to one end of the first mounting plate 331 facing the second limiting plate 162, and the plug plate 332 and the first mounting plate 331 are perpendicular to each other, so that the plug plate 332 and the first mounting plate 331 form a "T" shape in a cross-section perpendicular to the length direction of the auxiliary heater 3, thereby realizing the role of the plug plate 332 in reinforcing the structure of the first mounting plate 331, improving the structural strength of the first mounting plate 331, ensuring the reliability and stability of the first positioning structure 33, and further ensuring the coordination between the first positioning structure 33 and the second positioning structure 16.

[0064] In a further embodiment of the present invention, refer to the attached Figure 8 and attached Fig.12 As shown, the first positioning structure 33 also includes a second mounting plate 333, and the second mounting plate 333 and the fastener 15 are located on two opposite sides of the auxiliary heater 3.

[0065] In a further embodiment of the present invention, refer to the attached Figure 8 and attached Fig.11 As shown, the side of the limiting groove 163 facing the fastener 15 is open to avoid the second mounting plate 333, ensuring that the fixed end of the second mounting plate 333 is normally connected to the auxiliary heater 3, along the extension direction of the fastener 15 (refer to the attached Figure 7 The side of the limiting groove 163 away from the heat exchanger 2 is open, so that the second mounting plate 333 can be inserted into the limiting groove 163 to ensure the cooperation between the second mounting plate 333 and the limiting groove 163. It should be noted that the side of the limiting groove 163 away from the fastener 15, the side facing the heat exchanger 2 in the extension direction of the fastener 15, and the two sides along the length direction of the auxiliary heat exchanger 2 are all against the second mounting plate 333.

[0066] In some embodiments of the present invention, refer to the attached Figure 5 and attached Fig.10As shown, on the surface of the chassis 13 facing the top cover 12, there is a recessed portion 132 recessed in a direction away from the top cover 12, the second end 32 of the auxiliary heater 3 abuts against the bottom wall of the recessed portion 132, and the second positioning structure 16 is arranged on the side wall of the recessed portion 132. The arrangement of the recessed portion 132 can separate the installation area of ​​the auxiliary heater 3 from the heat exchanger 2, thereby reducing the difficulty of assembling the auxiliary heater 3. The second end 32 of the auxiliary heater 3 abuts against the bottom wall of the recessed portion 132, and can position the auxiliary heater 3 from the second end 32 of the auxiliary heater 3 to prevent the auxiliary heater 3 from moving in a direction away from the top cover 12. The second positioning structure 16 is arranged on the side wall of the recessed portion 132, so that the auxiliary heater 3 can be assembled close to the side wall of the recessed portion 132, and plays a pre-positioning and limiting role in assembly, thereby ensuring the cooperation between the first positioning structure 33 and the second positioning structure 16.

[0067] Specifically, refer to the attached Fig.12 As shown, the auxiliary heater 3 includes a heating section 34, a mounting cover 35 and a mounting base 36. The heating section 34 extends along the length direction of the auxiliary heat exchanger 2. The heating section 34 is used for heating.
