For example, the fastener 15 can be a screw.

[0055] Further, referring to the accompanying drawings Figure 2 and the accompanying drawings 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 flow direction, the air duct assembly 20 is located downstream of the heat exchanger assembly 10, which facilitates 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 driving of the air duct assembly 20, ensuring the heat exchange between the airflow and the heat exchanger assembly 10, guaranteeing the heating performance and cooling performance of the air conditioner 100, and improving the user experience.

[0056] Further, referring to the accompanying drawings Figure 13 , the accompanying drawings Figure 14 and the accompanying drawings Figure 15 As shown, the side of the air duct assembly 20 facing the heat exchanger assembly 10 has a protruding portion 201, the protruding portion 201 is oppositely arranged with the bottom disc 13, the auxiliary heater 3 is located between the protruding portion 201 and the bottom disc 13 and abuts against both the protruding portion 201 and the bottom disc 13, and along the arrangement direction of the heat exchanger assembly 10 and the air duct assembly 20 (the front-rear direction as shown in the accompanying drawings Figure 2 As shown, the opposite two outer walls of the auxiliary heater 3 abut against the inner side wall of the recessed portion 132 and the upstream side of the protruding portion 201, respectively, the support 1 and the air duct assembly 20 jointly limit the auxiliary heater 3, limit the freedom degree of the auxiliary heater 3 in the arrangement direction of the heat exchanger assembly 10 and the air duct assembly 20, prevent the fastener 15 from loosening and affecting the installation of the auxiliary heater 3, avoid the auxiliary heater 3 from being separated from the installation position, and further guarantee the installation reliability and stability of the auxiliary heater 3.

[0063] It should be noted that, as shown in the accompanying drawings of Figure 7 , the insertion plate 332 is connected to one end of the first mounting plate 331 facing the second limiting plate 162, and the insertion plate 332 and the first mounting plate 331 are perpendicular to each other, so that the cross section of the insertion plate 332 and the first mounting plate 331 perpendicular to the length direction of the auxiliary heater 3 forms a "T" shape, thereby realizing the role of the insertion plate 332 for the reinforcing 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 cooperation of the first positioning structure 33 and the second positioning structure 16.

The side of the limiting groove 163 facing away from the heat exchanger 2 is open in the extension direction of the fastener 15 (referring to the front-to-back direction shown in the accompanying drawings of

[0066] In some embodiments of the present application, reference is made to the accompanying drawings of Figure 5 and the accompanying drawings of Figure 10 As shown, the surface of the bottom plate 13 facing the top cover 12 has 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 assembly difficulty of the auxiliary heater 3. The second end 32 of the auxiliary heater 3 abuts against the bottom wall of the recessed portion 132, thereby positioning the auxiliary heater 3 from the second end 32 of the auxiliary heater 3, avoiding the auxiliary heater 3 from moving in a direction away from the top cover 12. The second positioning structure 16 arranged on the side wall of the recessed portion 132 can make the auxiliary heater 3 close to the side wall of the recessed portion 132 for assembly, thereby playing a pre-positioning and limiting role to ensure the cooperation of the first positioning structure 33 and the second positioning structure 16.

[0067] Specifically, as shown in the accompanying drawings of Figure 12 The auxiliary heater 3 includes a heating section 34, a mounting top cover 35 and a mounting base 36. The heating section 34 extends in the length direction of the auxiliary heat exchanger 2. The heating section 34 is used for heating. The mounting top cover 35 and the mounting base 36 are respectively sleeved on the heating section 34 in the length direction (referring to the front-to-back direction shown in the accompanying drawings of Figure 12The two ends (shown in the up-down direction) are used to fix the heating section 34 and install the heating section 34 on the bracket 1. The first end 31 of the auxiliary heater 3 is the end where the top cover 35 is located, and the second end 32 of the auxiliary heater 3 is the end where the mounting base 36 is located. The end of the mounting base 36 that is away from the top cover 35 abuts against the bottom wall of the recess 132.

[0068] In a further embodiment of the invention, reference is made to the appendix. Figure 13 As shown, the inner wall of the recess 132 is in contact with the auxiliary heater 3. Specifically, the inner wall of the recess 132 is in contact with the outer peripheral wall of the mounting base 36. The inner wall of the recess 132 and the outer peripheral wall of the mounting base 36 are designed to conform to the shape, so that the recess 132 is always in contact with the auxiliary heater 3, ensuring the limiting effect of the recess 132 on the auxiliary heater 3 and preventing the second end 32 of the auxiliary heater 3 from shifting within the recess 132.

[0069] In a specific example, see Appendix Figure 11 Appendix Figure 12 and attached Figure 13 As shown, the outer peripheral wall of the mounting base 36 has a protrusion 361 that protrudes outward toward the auxiliary heater 3. The inner sidewall of the recess 132 has a first groove 133 that matches the protrusion 361.

Specifically, the upstream side of the protrusion 201 is in contact with the outer peripheral wall of the mounting base 36. The upstream side of the protrusion 201 and the outer peripheral wall of the mounting base 36 are designed to conform to the shape, so that the protrusion 201 is always in contact with the auxiliary heater 3, ensuring the limiting effect of the protrusion 201 on the auxiliary heater 3 and preventing the second end 32 of the auxiliary heater 3 from shifting away from the protrusion 201.

[0071] In a specific example, see Appendix Figure 13 As shown, in conjunction with reference Figure 12 and Figure 15The outer peripheral wall of the mounting base 36 is provided with a protrusion 361 protruding outwardly of the auxiliary heater 3, and the upstream side of the protruding portion 201 is provided with a second groove 205 matched with the protrusion 361.
