[0002] In fresh air mode, all locations except the fresh air inlet of a fresh air air conditioner must be properly sealed to prevent air leakage, which reduces the fresh air volume. Therefore, a well-sealed fresh air system sealing installation structure is required. Furthermore, considering that fresh air systems often contain filter elements, ensuring secure attachment and quick assembly and disassembly of these elements is also a key concern. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides an air conditioner to strengthen the seal and facilitate the disassembly and assembly of the filter element.

[0028] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0029] According to one aspect of an embodiment of the present invention, there is provided an air conditioner, such as Figure 1As shown, the air conditioner comprises a lower panel 100 located at the lower front end of the air conditioner, wherein the lower middle portion of the lower panel 100 is covered with a fresh air outlet formed by a dense grid baffle. A fresh air inlet duct is provided at the rear end of the air conditioner.

[0030] Inside the lower panel 100, there is a fresh air system, which is mainly composed of a fresh air fan 400 and its air duct. The fresh air system is covered and sealed by the inner panel 200. A lower air outlet 250 is formed on the inner panel 200. The lower air outlet 250 is airtightly fitted with the fan outlet 410 of the fresh air fan 400. The inner panel 200 is tightly sealed and fixed to the boundary of the fresh air system suction chamber on all sides, thereby isolating the fresh air system suction chamber from the indoor air environment, thereby ensuring the relative air tightness of the fresh air system suction chamber, avoiding indoor air from leaking into the fresh air system suction chamber, thereby avoiding the reduction of the negative pressure of the suction chamber, and ensuring that the fresh air system suction chamber maintains sufficient negative pressure to introduce outdoor fresh air to the greatest extent. The specific installation structure of the inner panel 200 is as follows: Figure 1-5 shown.

[0031] In some embodiments, the inner panel 200 is constructed as a panel with a straight center and inwardly curved left and right sides. An upper protrusion 230 is provided at the upper end of the inner panel 200. The upper protrusion 230 is constructed as a boss structure protruding inward from the upper end of the inner panel 200. The boss structure of the upper protrusion 230 is a triangular protrusion structure with the longest protrusion in the center and a shorter protrusion on the sides. The top of the triangular protrusion is constructed in a smooth arc shape. The triangular protrusion structure cooperates with the shape of the inner panel 200, which is straight in the center and inwardly curved on the left and right sides, so that the upper protrusion 230 as a whole forms a "W"-shaped protrusion structure with a circular arc transition.

[0032] Above the fresh air system, an upper clamping part 600 is provided. Figure 3 As shown, the upper clamping portion 600 is formed into a structure with protruding ends and a concave middle, which is consistent with the shape of the upper protruding portion 230. The upper clamping portion 600 is provided with an upper clamping groove 610, as shown in FIG. Figure 4 As shown, the upper slot 610 is formed by a gap between a first protrusion 611 located at the upper side and a second protrusion 612 located at the lower side. The gap width of the upper slot 610 is slightly larger than the width of the upper protrusion 230.

[0033] Thus, the upper end of the inner panel 200 is inserted into the gap of the upper slot 610 by the upper protrusion 230 and is tightly fitted. The "W"-shaped structure with an arc transition is conducive to precise positioning and when the protrusion 230 is tightly fitted with the upper slot 610, it can not only limit the front and rear directions, but also limit and fix the left and right directions. Therefore, the "W"-shaped structure with an arc transition can completely limit the six degrees of freedom of the front, rear, upper, lower, left and right of the upper end of the inner panel 200, prevent dislocation and fitting gaps, and improve the sealing and airtightness of the upper end.

[0034] In some embodiments, protruding side mounting portions 220 are provided on both sides of the inner panel 200. Figure 2 、 5 One end of the side mounting portion 220 extends outward to form a matching thin-wall mounting structure, which tightly fits with the front clamping portion 520 at the front end of the side panels 500 on both sides of the fresh air system. The mounting holes on the side mounting portion 220 are tightly pressed against the front clamping portion 520 at the front end of the side panels 500 by screws.

[0035] At the same time, a first side slot 222 is provided on the formed matching thin-walled mounting structure. The first side slot 222 is positioned to coincide with the second side slot 510 at the front end of the side panel 500 to form a matching slot, and is clamped and pressed together with the formed matching slot through the buckles on both sides of the lower panel 100 to prevent the side mounting portion 220 from being locally deformed due to the local stress of the screw installation to form a wavy local bending, thereby forming a matching gap with the side panel 500 and causing a decrease in air tightness.

[0036] The side mounting portion 220 is further formed with a side buckle 221 protruding inwardly. The side buckle 221 is configured as a hook-shaped structure with one end protruding inwardly from the side mounting portion 220 and the other end being bent backward. Figure 5 As shown, the side panel 500 is composed of an inwardly opening front clamping portion 520 and an outwardly opening rear clamping portion 530. The rear end of the front clamping portion 520 is integrally connected to the front end of the rear clamping portion 530. The front clamping portion 520 and the rear clamping portion 530 are integrally formed into an "S"-shaped structure. The front end surface of the front clamping portion 520 is clamped and fixed with the rear end surface of the side mounting portion 220 and the inner end surface of the side buckle 221, while the rear end surface of the rear clamping portion 530 is fixed and fixed to the air conditioner housing component at its rear end. The outer end of the front clamping portion 520 is clamped and fixed by the air conditioner housing. The end of the front clamping portion 520 is further bent outward to form a hook shape.

[0037] Thus, when both sides of the inner panel 200 are fastened to the side panels 500 via the side mounting portions 220, the ends of the side clips 221 of the side mounting portions 220 come into contact and squeeze with the front end surface of the front clip portion 520, causing the front end surface of the front clip portion 520 to bend backward and elastically deform. Furthermore, guided by the deformed front end surface of the front clip portion 520, the outer end surfaces of the side clips 221 come into contact and limit contact with the inner end surface of the front clip portion 520. When the rear end surfaces of the side mounting portions 220 come into contact with the front end surface of the front clip portion 520, the side mounting portions 220 on both sides are subjected to the inward elastic resetting and clamping force of the left and right side panels 500, thereby forming a seal.

[0038] After the upper end and both sides of the inner panel 200 are snap-fitted and sealed, the inner panel 200 is fixed and sealed to the lower part of the air conditioner by screws, thereby isolating the suction chamber of the fresh air system from the indoor air environment, thereby ensuring the relative air tightness of the suction chamber of the fresh air system, avoiding indoor air from leaking into the suction chamber of the fresh air system, thereby avoiding the reduction of the negative pressure of the suction chamber, and allowing the suction chamber of the fresh air system to maintain sufficient negative pressure to introduce outdoor fresh air to the greatest extent.

[0039] Filter cartridge mounting portions 300 are located at the fan inlets 420 on either side of the fresh air blower 400. The filter cartridge mounting portions 300 include a filter cartridge housing 320 and a filter cartridge support 310. The filter cartridge housing 320 is connected to the air inlet volute of the fresh air blower 400. The filter cartridge support 310 is removably inserted and retracted within the filter cartridge housing 320. The filter cartridge housing 320 is constructed as a housing structure larger than the air inlet volute of the fresh air blower 400. The filter cartridge housing 320 and the air inlet volute of the fresh air blower 400 are connected via an annular step. The annular step helps secure the filter cartridge support 310 within the filter cartridge housing 320.

[0040] like Figure 6 As shown, the filter element carrier 310 includes a carrier plate at the lower end and a support plate positioned near the inlet volute of the fresh air blower 400. The filter element 330 is mounted on the carrier plate and supported horizontally by the support plate. The support plate can be snapped onto an annular step to prevent suction from the fan inlet 420 from drawing the filter element 330 into the fresh air blower 400. The support plate is constructed as a low-resistance, air-permeable partition. It can have either a coarse mesh or a grid structure.

[0041] A rear plate is formed at the rear end of the filter element supporting portion 310 to provide front and rear position limiting support for the filter element 330 in the filter element supporting portion 310 .

[0042] A lifting portion 311 is formed at the front end of the filter element carrier 310 to facilitate pulling the filter element carrier 310 out of the filter element housing 320 .

[0043] A hollow portion 240 corresponding to the filter element mounting portion 300 is provided on the inner panel 200 , and the lifting portion 311 of the filter element mounting portion 300 can at least partially extend from the hollow portion 240 .

[0044] The lifting portion 311 includes a second concave cavity 312 that is open on the inside and closed on the outside. Multiple reinforcement portions 313 are spaced apart within the second concave cavity 312. These reinforcement portions 313 are thin plate-shaped and evenly spaced within the second concave cavity 312 to secure and reinforce the front end surface of the second concave cavity 312, preventing deformation and damage caused by pulling forces.

[0045] A first concave cavity 210 is provided at the inner end of the hollow portion 240. The first concave cavity 210 is configured such that, at the location where it engages with the lifting portion 311 of the filter element mounting portion 300, the inner panel 200 is partially sunken to form a cavity. This allows the operator to insert their hand into the first concave cavity 210, then bend their fingers into the second concave cavity 312, and then hook their fingers onto the inner side of the front end of the second concave cavity 312, thereby smoothly withdrawing the filter element support portion 310 for removal and replacement of the filter element 330.

[0046] When the filter element carrier 310 is fully inserted into the filter element housing 320 and fixedly installed, the front end surface of the second cavity 312 is flush with the front end surface of the inner panel 200, forming a smooth and integrated whole. In particular, the filter element mounting portion 300 and the inner panel 200 are sealed together, thereby ensuring the relative airtightness of the air intake chamber.
