[0050] Currently, floor-standing air conditioners on the market are equipped with PTC heaters to heat the air they process. However, traditional floor-standing air conditioners typically encapsulate the PTC heater between the heat exchanger and the ductwork. Maintaining or replacing the PTC heater requires first removing the top cover and front panel of the floor-standing air conditioner, then disassembling the ductwork, and finally removing the PTC heater for maintenance or replacement. This makes the process of removing and installing the PTC heater cumbersome and significantly increases the difficulty of doing so.

[0051] In view of this, the present invention provides an embodiment of an air conditioning heat exchange component, which can be installed in a floor-standing air conditioner. The floor-standing air conditioner can open its top cover, and then the PTC heater can be moved out or installed along the length of the heat exchanger of the air conditioning heat exchange component. This eliminates the need to disassemble the air duct components or panel on the front side of the heat exchanger, greatly reducing the operation steps of disassembling and assembling the PTC heater, thereby effectively reducing the difficulty of disassembling and assembling the PTC heater and realizing easy disassembly and replacement of the PTC heater.

[0052] Please see Figures 1 to 3 In one embodiment of the air conditioning heat exchange assembly of the present invention, the air conditioning heat exchange assembly includes a mounting bracket 100, a heat exchanger 200, and a PTC heater 300. The mounting bracket 100 includes a base 110 and a top seat 120 facing each other; the heat exchanger 200 is mounted on the mounting bracket 100, and the heat exchanger 200 is located between the base 110 and the top seat 120 of the mounting bracket 100; the PTC heater 300 is disposed on the air outlet side of the heat exchanger 200. The top seat 120 is provided with a mounting port 121 for inserting and removing the PTC heater 300; one end of the PTC heater 300 is pluggably connected to the base 110, and the other end of the PTC heater 300 is detachably mounted to the mounting port 121 of the top seat 120.

[0053] Specifically, the mounting bracket 100 has a base 110 at its lower end and a top seat 120 at its upper end. A heat exchanger 200 is mounted on one side of the mounting bracket 100, located between the base 110 and the top seat 120, and supported by the base 110. The heat exchanger 200 is curved along the width of the mounting bracket 100 to partially surround the impeller on the air duct component. A PTC heater 300 is located on the air outlet side of the heat exchanger 200, specifically within the curved cavity of the heat exchanger 200. When the air conditioning heat exchange assembly is operating, the airflow passing through the heat exchanger 200 is heated by the PTC heater 300, increasing the airflow temperature to form hot air, which is then delivered to the user.

[0054] The PTC heater 300 extends in a long strip along the height direction of the mounting bracket 100, and the PTC heater 300 can be installed or removed from the mounting port 121 along the direction from the base 110 to the top seat 120 (that is, the height direction of the mounting bracket 100). Since one end of the PTC heater 300 is pluggably connected to the base 110 of the mounting bracket 100, and the other end of the PTC heater 300 is detachably mounted to the mounting port 121 of the top seat 120 of the mounting bracket 100, when disassembling the PTC heater 300, the operator can first remove the PTC heater 300 from the mounting port 121 of the top seat 120 of the mounting bracket 100, and then move the PTC heater 300 from the mounting port 121 along the direction from the base 110 to the top seat 120, so that the PTC heater 300 is pulled out from the base 110 of the mounting bracket 100; then continue to move the PTC heater 300 until the PTC heater 300 is completely removed from the mounting port 121, thus completing the disassembly of the PTC heater 300. Installing the PTC heater 300 is the reverse operation, which will not be described in detail here.

[0055] Based on this, after the air conditioning heat exchange component is installed inside the floor-standing air conditioner, the air conditioning heat exchange component is located between the air inlet and the duct component of the floor-standing air conditioner, and the top mount 120 of the air conditioning heat exchange component is positioned opposite to the top cover of the floor-standing air conditioner. When it is necessary to disassemble the PTC heater 300, simply remove the top cover of the floor-standing air conditioner and remove the PTC heater 300 from the top mount 120 of the mounting bracket 100 (see the above description for details), without needing to disassemble the duct component or the front panel of the duct component.

[0056] The technical solution of this invention involves installing a heat exchanger 200 between the base 110 and the top seat 120 of the mounting bracket 100, and placing a PTC heater 300 on the air outlet side of the heat exchanger 200. The top seat 120 has a mounting port 121 for inserting and removing the PTC heater 300 along the direction from the base 110 to the top seat 120. One end of the PTC heater 300 is pluggably connected to the base 110, and the other end is detachably installed in the mounting port 121 of the top seat 120. With this design, after the air conditioning heat exchange assembly is installed into the floor-standing air conditioner, when needed... To disassemble the PTC heater 300, the operator can first remove the top cover plate above the air conditioning heat exchange component of the floor-standing air conditioner. Then, remove the PTC heater 300 from the mounting port 121 from the top seat 120 of the mounting bracket 100. Move the PTC heater 300 from the mounting port 121 along the direction from the base 110 to the top seat 120, so that the PTC heater 300 is pulled out from the base 110 of the mounting bracket 100. Finally, continue moving the PTC heater 300 until it is completely removed from the mounting port 121, thus completing the disassembly of the PTC heater 300. During this disassembly process, it is not necessary to remove the air duct component or the front panel of the air duct component, which greatly reduces the operation steps of disassembling and assembling the PTC heater 300, thereby effectively reducing the difficulty of disassembling and assembling the PTC heater 300 and making the PTC heater 300 easy to disassemble and replace.

[0057] Please see Figure 3 and Figure 14 In one embodiment, the PTC heater 300 includes a heating rod 310 and a plug-in seat 320 and a fixed seat 330 respectively connected to both ends of the heating rod 310; wherein the plug-in seat 320 is pluggably connected to the base 110, and the fixed seat 330 is detachably installed in the mounting port 121 of the top seat 120.

[0058] Specifically, the PTC heater 300 can have one, two, or more heating rods 310. Each heating rod 310 is elongated and extends along the height of the mounting bracket 100. The heating rod 310 is connected to the electrical control assembly via a wire 340. The two ends of the heating rod 310 are a first end 311 and a second end 312; the first end 311 is fixedly connected to the plug-in socket 320, and the second end 312 is fixedly connected to the fixing base 330. The PTC heater 300 is pluggably connected to the base 110 of the mounting bracket 100 via the plug-in socket 320, and is detachably connected to the mounting port 121 on the top seat 120 of the mounting bracket 100 via the fixing base 330.

[0059] There are various design options for the specific structure of the plug-in socket 320 of the PTC heater 300 and the plug-in connection method between it and the base 110 of the mounting bracket 100. Please refer to [link / reference]. Figures 5 to 7 In this embodiment, the plug-in socket 320 of the PTC heater 300 is provided with a insertion cavity 321, and the first end 311 of the heating rod 310 is inserted into the insertion cavity 321 to be connected and fixed with the plug-in socket 320. Specifically, the plug-in socket 320 is provided with two insertion cavities 321; the first ends 311 of the two heating rods 310 are respectively inserted into the two insertion cavities 321 of the plug-in socket 320 to be connected and fixed with the plug-in socket 320.

[0060] Please see Figure 4 , Figure 6 and Figure 7 In one embodiment, a plug-in slot 111 is provided on the base 110 of the mounting bracket 100, and the plug-in socket 320 of the PTC heater 300 is pluggably installed in the pluggable slot 111, thereby realizing a pluggable connection between the PTC heater 300 and the base 110. Specifically, as shown in the figure... Figure 11 and Figure 12 As shown, an annular rib 113 is protruding from the upper plate of the base 110, and a insertion / removal groove 111 is formed on the inner side of the annular rib 113. The shape of the insertion / removal groove 111 is consistent with the shape of the insertion / removal seat 320 of the PTC heater 300, so that the insertion / removal seat 320 can be fitted into the insertion / removal groove 111, and after applying an upward force to the PTC heater 300, the insertion / removal seat 320 of the PTC heater 300 can be pulled out from the insertion / removal groove 111.

[0061] Considering that when installing the PTC heater 300, after the plug-in socket 320 of the PTC heater 300 is inserted from the mounting port 121 of the top seat 120 into the air outlet side of the heat exchanger 200, the operator's vision may be obstructed by the top seat 120, making it difficult to accurately align the plug-in socket 320 of the PTC heater 300 with the plug-in slot 111 of the mounting bracket 100. Therefore, in this embodiment, a plug-in guide post 322 protrudes from the bottom of the plug-in socket 320, and a plug-in guide hole 112 is provided at the bottom of the plug-in slot 111 for inserting the plug-in guide post 322. The number of plug-in guide posts 322 can be one, two, or more.

[0062] Specifically, the bottom of the plug-in socket 320 is provided with two plug-in guide posts 322; the bottom of the plug-in groove 111 is provided with two plug-in guide holes 112, and the two plug-in guide holes 112 are respectively used for the two plug-in guide posts 322 to be plugged in one by one. When installing the PTC heater 300, after inserting the PTC heater 300 from top to bottom into the air outlet side of the heat exchanger 200 through the mounting port 1212, insert the plug-in guide post 322 on the plug-in socket 320 of the PTC heater 300 into the plug-in groove 111 of the base 110, so that the plug-in guide post 322 is aligned with the plug-in guide hole 112 in the plug-in groove 111. Then, apply an external force to the PTC heater 300 so that the plug-in guide post 322 is inserted directly into the plug-in guide hole 112, thereby plugging and unplugging the PTC heater 300 and the base 110. This reduces the difficulty of inserting the PTC heater 300 into the base 110 of the mounting bracket 100.

[0063] Please see Figure 6 , Figure 7 and Figure 14 Furthermore, the diameter of the insertion guide post 322 gradually decreases from the end closest to the fixing cavity 331 to the end furthest from the fixing cavity 331, making the insertion guide post 322 tapered. That is, the upper diameter of the insertion guide post 322 is larger, while the lower diameter is smaller. During the insertion process of the insertion guide post 322 into the insertion guide hole 112 in the insertion groove 111, the lower end of the insertion guide post 322 is less likely to interfere with the periphery of the entrance end 112 of the insertion guide hole 112, thereby reducing the resistance of the insertion guide post 322 into the insertion guide hole 112, and making it easier for the operator to align and insert the insertion guide post 322 with the insertion guide hole 112.

[0064] In another embodiment, the insertion guide hole 112 has an inlet end 1121 for the insertion guide post 322 to be inserted. To facilitate the insertion of the insertion guide post 322 into the insertion guide hole 112, the inlet end 1121 can be flared outwards, so that the inlet end 1121 is flared outwards from bottom to top. This can reduce the resistance of the inlet end 1121 of the insertion guide hole 112 to the insertion guide post 322, and facilitate guiding the insertion guide post 322 to be inserted into the insertion guide hole 112 from the inlet end 1121.

[0065] Based on any of the above embodiments, the specific structure of the mounting base 330 of the PTC heater 300 and the detachable connection between it and the top seat 120 of the mounting bracket 100 can also be designed in various ways. Please refer to [link / reference]. Figure 3 , Figure 4 and Figure 11In this embodiment, the top seat 120 of the mounting bracket 100 is provided with a duct sealing plate 122 for cooperating with the duct component. The duct sealing plate 122 is located above the air outlet side of the heat exchanger 200, and is used to contact and cooperate with the upper end of the duct component of the floor-standing air conditioner to seal the air duct on the air outlet side of the heat exchanger 200. Here, in order to facilitate the removal or installation of the PTC heater 300 from the mounting port 121, optionally, a notch 1211 is formed on the duct sealing plate 122 to mate with the mounting port 121; the air conditioning heat exchange assembly also includes a positioning block 400, which is detachably installed at the notch 1211 to define the fixing seat 330 (e.g., Figure 5 (As shown).

[0066] Specifically, after the PTC heater 300 is inserted from the mounting port 121 on the top seat 120 of the mounting bracket 100 into the air outlet side of the heat exchanger 200, the fixing seat 330 of the PTC heater 300 is detachably connected to the top seat 120 of the mounting bracket 100, and the positioning block 400 is detachably installed at the notch 1211. This allows the positioning block 400 to press and confine the fixing seat 330 of the PTC heater 300 within the mounting port 121 of the top seat 120, preventing the fixing seat 330 from shaking or falling off the mounting port 121. When it is necessary to disassemble the PTC heater 300, the positioning block 400 is first removed from the top seat 120, and then the PTC heater 300 is disassembled. Because a notch 1211 is formed on the air duct sealing plate 122 to mate with the mounting port 121, the notch 1211 can increase the area of ​​the mounting port 121, thereby reducing the interference of the periphery of the mounting port 121 to the PTC heater 300 during the disassembly and assembly of the PTC heater 300.

[0067] Optionally, the duct sealing plate 122 is divided into two sub-sealing plates 1221 by a notch 1211 (e.g., Figure 4 (As shown); the positioning block 400 is provided with a filling sealing surface 410, which is arc-shaped and extends from one of the sub-sealing plates 1221 to the other sub-sealing plate 1221 (as shown). Figure 5 and Figure 20 (As shown). This arrangement is designed so that the filling sealing surface 410 of the positioning block 400 connects with the surfaces of the two sub-sealing plates 1221 of the duct sealing plate 122 to form a complete sealing surface, so as to make circumferential contact with the end of the duct component; wherein, the filling sealing surface 410 of the positioning block 400 is adapted to the arc-shaped surface of the end of the duct component. Specifically, the duct component includes an end plate for mounting the impeller; the filling sealing surface 410 of the positioning block 400 makes contact with the periphery of the end plate to avoid air leakage gaps between the two.

[0068] Please see Figure 5 , Figure 6 and Figure 8 In one embodiment, the back of the fixing base 330 facing away from the back of the positioning block 400, and / or the two end faces of the fixing base 330 adjacent to its back are further provided with mounting plates 332, which are detachably connected to the top seat 120. Specifically, the fixing base 330 has a back facing away from the positioning block 400, and end faces located at the two adjacent ends of the back; the mounting plate 332 extends from one end face of the fixing base 330 through its back to the other end face (see mounting plate 332). Figures 15 to 17 The mounting plate 332 is located on the outer plate surface of the top seat 120 facing away from the heat exchanger 200, which facilitates the operator to detachably connect the mounting plate 332 of the fixing seat 330 to the top seat 120 from above.

[0069] To ensure the airtightness of the air duct after the air conditioning heat exchange component is installed inside the floor-standing air conditioner, when the mounting bracket 330 is installed in the mounting port 121, the mounting bracket 330 should preferably be in a sealing fit with the periphery of the mounting port 121 to prevent airflow from the outlet side of the heat exchanger 200 from leaking out of the mounting port 121. Therefore, please refer to... Figure 8 , Figure 11 and Figure 13 Optionally, an outer stiffener 123 is provided on the outer plate surface of the top seat 120 facing away from the heat exchanger 200. The outer stiffener 123 is provided along the outer periphery of the mounting opening 121 and is in contact with the lower surface of the mounting plate 332.

[0070] Specifically, one end of the outer stiffening plate 123 is connected to one of the sub-sealing plates 1221, and then extends through the edge of the mounting opening 121 to the other sub-sealing plate 1221, where it is connected. The lower surface of the mounting plate 332 of the fixing seat 330 rests on the top of the outer stiffening plate 123, thereby sealing the gap between the mounting opening 121 and the fixing seat 330 and reducing air leakage.

[0071] Furthermore, an inner stiffening plate 124 is protruding from the inner plate surface of the top seat 120 facing the heat exchanger 200. The inner stiffening plate 124 is arranged along the inner periphery of the mounting opening 121 and surrounds the outer periphery of the fixing seat 330. Specifically, the inner stiffening plate 124 extends from one end of the notch 1211 of the mounting opening 121 through the edge of the mounting opening 121 to the other end of the notch 1211, so that the inner stiffening plate 124 and the outer stiffening plate 123 surround the mounting opening 121, thereby forming a cavity for the fixing seat 330 to be accommodated. In addition, when the airflow passes through the upper end of the heat exchanger 200, part of the airflow will be blocked by the inner stiffening plate 124 of the top seat 120, and will therefore blow forward along the outer periphery of the inner stiffening plate 124, bypassing the inner stiffening plate 124 and not easily deflected upward into the mounting opening 121, thus reducing the likelihood of air leakage from the mounting opening 121.

[0072] Please see Figure 8 , Figure 11 and Figure 13 For the detachable connection between the mounting base 330 of the PTC heater 300 and the top seat 120 of the mounting bracket 100, optionally, a connecting portion 333 is provided on the mounting plate 332 of the mounting base 330, and a mating portion 12b corresponding to the connecting portion 333 is protruding on the outer plate surface of the top seat 120. The mating portion 12b and the connecting portion 333 are connected by connecting screws. Specifically, the mating portion 12b is a threaded post provided on the outer plate surface of the top seat 120, and the threaded post is located on the outside of the outer stiffening plate 123; the connecting portion 333 is a connecting hole corresponding to the threaded post. After the mounting base 330 is inserted into the mounting opening 121, the mounting plate 332 of the mounting base 330 rests on the top of the outer stiffening plate 123, and then connecting screws are used to sequentially pass through the connecting portion 333 on the mounting plate 332 and the mating portion 12b of the top seat 120, thereby connecting and fixing the two together.

[0073] Furthermore, to facilitate the insertion of the fixing seat 330 into the mounting opening 121, a mounting guide post 334 may be provided protruding from the back of the fixing seat 330, and the top seat 120 may have a mounting guide groove 12a on the edge of the mounting opening 121 opposite to the notch 1211 for inserting the mounting guide post 334. Specifically, the portion of the outer stiffening plate 123 opposite to the notch 1211 of the mounting opening 121 is recessed in a direction away from the notch 1211, thereby forming a mounting guide groove 12a in the outer stiffening plate 123.

[0074] During assembly, the mounting base 330 of the PTC heater 300 is first placed at the notch 1211 of the mounting port 121. Then, the mounting guide post 334 on the back of the mounting base 330 is aligned with the mounting guide groove 12a on the outer stiffener plate 123. Pressure is then applied to the mounting base 330 to insert the mounting guide post 334 into the mounting guide groove 12a, thereby guiding the mounting base 330 into the mounting port 121. Thus, after the mounting guide post 334 is inserted into the mounting guide groove 12a, the mounting base 330 is positioned within the mounting port 121, making it difficult for the mounting base 330 to move left or right. Therefore, even without manually supporting the mounting base 330, the connecting part 333 of the mounting base 330 can be connected and fixed to the mating part 12b of the top seat 120.

[0075] Please see Figure 9 , Figure 10 and Figure 13Regarding the detachable connection between the positioning block 400 and the top seat 120 of the mounting bracket 100, optionally, one of the outer stiffening plate 123 and the positioning block 400 is provided with a positioning pin 420, and the other is provided with a positioning groove 12c for the positioning pin 420 to be inserted into; and / or, one of the outer stiffening plate 123 and the positioning block 400 is provided with a positioning buckle 12d, and the other is provided with a fastening part 430 for the positioning buckle 12d to be fastened. The positioning pin 420 and the positioning buckle 12d can be provided simultaneously, or only one of them can be provided.

[0076] Specifically, the outer stiffening plate 123 has positioning grooves 12c at both ends near the notch 1211 of the mounting opening 121. The positioning grooves 12c are recessed downwards from the top of the outer stiffening plate 123. The outer stiffening plate 123 has a positioning buckle 12d on one side of the positioning groove 12c, and the positioning buckle 12d is an elastic snap fastener. When installing the positioning block 400, first insert the positioning pin 420 of the positioning block 400 into the positioning groove 12c of the outer stiffening plate 123 from top to bottom, so that the positioning block 400 is suspended in the notch 1211 of the mounting opening 121; then fasten the positioning buckle 12d on the outer stiffening plate 123 into the fastening part 430 of the positioning block 400, thereby connecting and fixing the positioning block 400 to the top seat 120. When removing the positioning block 400, simply reverse the operation.

[0077] Please see Figure 16 , Figure 18 and Figure 19 In one embodiment, the mounting base 330 is provided with a mounting cavity 331 for inserting the heating rod 310. Specifically, the second end 312 of the heating rod 310 is inserted into the mounting cavity 331 of the mounting base 330 and is connected and fixed to the mounting base 330. To enhance the firmness of the connection between the mounting base 330 and the heating rod 310, a fixing post 313 protrudes from the end of the heating rod 310 that mates with the mounting cavity 331; the top of the mounting cavity 331 is provided with a fixing hole 335 for inserting the fixing post 313. That is, the heating rod 310 has a fixing post 313 protruding from the end face of the second end 312, and the fixing post 313 can be interference-fitted with the fixing hole 335.

[0078] Please see Figures 17 to 19 Furthermore, considering that the heating rod 310 is connected to the wire 340 for electrical connection with the external electrical control component, the portion of the mounting base 330 exposed above the mounting opening 121 may optionally have a wire outlet groove 336 for the wire 340 connected to the heating rod 310 to pass through. Specifically, the wire outlet groove 336 extends into the fixing cavity 331 of the mounting base 330, and the second end 312 of the heating rod 310 is connected to the wire 340, allowing the wire 340 to pass through the fixing cavity 331 and the wire outlet groove 336 to the outside, thereby connecting to the external electrical control component.

[0079] Please see Figure 2 , Figure 11 and Figure 13 Furthermore, a first wire clamp 337 for fixing the wire 340 is provided on one side of the outlet groove 336 of the fixing base 330; and / or, a second wire clamp 125 for fixing the wire 340 is provided on the outer plate surface of the top base 120. Only one of the first wire clamp 337 and the second wire clamp 125 may be present, or both may be present. When the wire 340 passes through the outlet groove 336, the first wire clamp 337 clamps the wire 340 onto the outlet groove 336, preventing the wire 340 from falling out of the outlet groove 336. After the wire 340 passes through the outlet groove 336, the second wire clamp 125 clamps the wire 340 onto the outer plate surface of the top base 120, thereby fixing the wire 340 to the top base 120, reducing the movement of the wire 340, and ensuring the stability of the connection between the wire 340 and the heating rod 310 and the electronic control components.

[0080] This invention also provides a floor-standing air conditioner, which includes a housing and an air conditioning heat exchange assembly. The housing includes a shell body, a front panel mounted on the front side of the shell body, and a top cover plate mounted on the top of the shell body. The air conditioning heat exchange assembly is installed inside the shell body, and its top mount 120 is disposed opposite to the top cover plate. The specific structure of the air conditioning heat exchange assembly is as described in the above embodiments. Since this floor-standing air conditioner adopts all the technical solutions of all the above embodiments, it also possesses all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0081] In one embodiment, the housing of the floor-standing air conditioner has an air inlet and an air outlet; the duct component of the floor-standing air conditioner is installed inside the housing to form an air duct. The duct component includes a volute assembly for forming the air duct and a fan wheel installed inside the volute assembly. The air conditioning heat exchange assembly is disposed between the air inlet of the housing and the duct component, and the sealing surface 410 of the positioning block 400 of the air conditioning heat exchange assembly is in a sealing fit with the duct component.

[0082] Since one end of the PTC heater 300 of the air conditioning heat exchange assembly is pluggably connected to the base 110 of the mounting bracket 100, and the other end of the PTC heater 300 is detachably mounted on the mounting port 121 of the top seat 120 of the mounting bracket 100, when it is necessary to remove the PTC heater 300 of the air conditioning heat exchange assembly, the operator can first remove the top cover of the floor-standing air conditioner to expose the top seat 120 of the mounting bracket 100; then remove the PTC heater 300 from the mounting port 121 from above the top seat 120 of the mounting bracket 100, and move the PTC heater 300 from the mounting port 121 along the direction from the base 110 to the top seat 120, so that the PTC heater 300 is pulled out from the base 110 of the mounting bracket 100; finally, continue to move the PTC heater 300 until the PTC heater 300 is completely removed from the mounting port 121, thus completing the removal of the PTC heater 300. During this disassembly process, there is no need to remove the air duct components or the front panel of the air duct components, which greatly reduces the operation steps of disassembling and assembling the PTC heater 300, thereby effectively reducing the difficulty of disassembling and assembling the PTC heater 300 and making the PTC heater 300 easy to disassemble and replace.

[0083] The technical solution of this invention for a floor-standing air conditioner involves installing an air conditioning heat exchange assembly between the air inlet of the casing and the air duct components. The heat exchanger 200 is mounted between the base 110 and the top mount 120 of the mounting bracket 100, and a PTC heater 300 is positioned on the air outlet side of the heat exchanger 200. The top mount 120 has a mounting port 121 for inserting and removing the PTC heater 300 along the direction from the base 110 to the top mount 120. One end of the PTC heater 300 is pluggably connected to the base 110, and the other end is detachably mounted to the mounting port 121 of the top mount 120. This design allows the air conditioning heat exchange assembly to be installed... After installation in the floor-standing air conditioner, when the PTC heater 300 needs to be disassembled, the operator can first remove the top cover plate above the air conditioning heat exchange component of the floor-standing air conditioner, then remove the PTC heater 300 from the mounting port 121 from the top seat 120 of the mounting bracket 100, and move the PTC heater 300 from the mounting port 121 along the direction from the base 110 to the top seat 120, so that the PTC heater 300 is pulled out from the base 110 of the mounting bracket 100; finally, continue to move the PTC heater 300 until it is completely removed from the mounting port 121, thus completing the disassembly of the PTC heater 300. During this disassembly process, it is not necessary to disassemble the duct components or the front panel of the duct components, which greatly reduces the operation steps for disassembling and assembling the PTC heater 300, thereby effectively reducing the difficulty of disassembling and assembling the PTC heater 300 and making the PTC heater 300 easy to disassemble and replace.
