The air inlet of modern floor-standing air conditioners is generally located on the back panel, and to improve the cleanliness of the incoming airflow, a filter is usually installed inside the inlet. However, these filters are typically installed inside the air conditioner unit. Cleaning or maintaining the filter requires disassembling the back panel, a cumbersome, time-consuming, and labor-intensive process with low efficiency for both cleaning and maintenance. Utility Model Content

[0003] The problem solved by this utility model is how to achieve quick disassembly and assembly of filter screens, which facilitates cleaning or maintenance of filter screens, simplifies disassembly and assembly steps, saves time and effort, improves disassembly and assembly efficiency, improves cleaning and maintenance efficiency, and enhances user experience.

[0004] To solve the above problems, the technical solution of this utility model is implemented as follows: Firstly, this utility model provides a housing assembly including a back plate, a filter grille, and a latch. The back plate has an air inlet, the filter grille is hung on the outside of the back plate and covers the air inlet, the filter grille has a guide groove, the back plate has a mating structure, and the latch slides with the guide groove. The latch is used to lock or unlock with the mating structure when sliding relative to the guide groove. Compared with the prior art, the housing assembly provided by this utility model, due to the use of a filter grille hung on the outside of the back plate and a latch that selectively engages with the mating structure, enables quick assembly and disassembly of the filter grille, facilitating cleaning or maintenance of the filter grille, simplifying assembly and disassembly steps, saving time and effort, improving assembly and disassembly efficiency, improving cleaning and maintenance efficiency, and enhancing the user experience.

[0005] Furthermore, the filter grid includes a filter screen and a grid body, with the grid body attached to the back panel; The filter screen is integrally formed with the grille body; or the filter screen is bonded to the grille body; or the filter screen is inserted between the grille body and the back plate, with a handle groove at one end of the filter screen. The grille body and the back plate work together to limit the filter screen and prevent it from falling off.

[0006] Furthermore, the grille body includes a grille section, a first side plate, a second side plate, a top plate, and a bottom plate. The top plate, first side plate, bottom plate, and second side plate are connected end-to-end and together form an air passage cavity. The air passage cavity communicates with the air inlet. The grille section is disposed within the air passage cavity and is simultaneously connected to the top plate, first side plate, bottom plate, and second side plate. A guide groove is formed in the bottom plate. The grille section is used to improve the connection strength of the top plate, first side plate, bottom plate, and second side plate.

[0007] Furthermore, the first side panel is provided with a first hook, the second side panel is provided with a second hook, and the back panel has a first hooking groove and a second hooking groove. The first hooking groove and the second hooking groove are arranged opposite each other on both sides of the air inlet. The first hook is hooked into the first hooking groove, and the second hook is hooked into the second hooking groove. The first hook and the second hook work together to simultaneously realize the hooking function of the first side panel and the second side panel, improve the balance of the grille body hooked onto the back panel, and prevent the grille body from tilting or tipping over.

[0008] Furthermore, the top plate is equipped with a buckle, and the back plate is provided with a slot. The slot is located above the air inlet, and the buckle engages with the slot. The back plate can limit and fix the top plate through the engagement of the buckle and the slot, so as to further fix the relative position of the top plate and the back plate, thereby fixing the relative position of the grille body and the back plate and preventing the grille body from accidentally detaching from the back plate. And / or, the base plate is provided with inserts, and the back plate has slots located below the air inlet. The inserts and slots are engaged. The back plate can guide and limit the base plate through the engagement of the inserts and slots, thereby limiting the hanging direction of the grille body and improving the stability of the grille body hanging process.

[0009] Furthermore, the mating structure is a mating groove, with a first sidewall and a second sidewall positioned opposite each other. A limiting buckle protrudes from the first sidewall towards the second sidewall, located at the opening of the mating groove and spaced apart from the second sidewall. A locking buckle extends into the mating groove and is used to engage or disengage with the limiting buckle, thereby achieving the locking or unlocking function of the filter screen.

[0010] Furthermore, the back panel is equipped with a reinforcing mesh located inside the air inlet. The filter grille includes a main grille and multiple sub-grille strips, which are spaced apart and connected to the main grille. The reinforcing mesh overlaps with the main grille. This design allows for alignment during filter grille installation, preventing mistake-proofing and improving installation efficiency. It also reduces the overall thickness of the reinforcing mesh and main grille after assembly, increasing the structural compactness of the housing assembly and reducing its space requirements. Finally, it effectively reduces wind resistance, increases airflow, and ensures optimal air intake performance.

[0011] Furthermore, the reinforcing mesh includes a plurality of first reinforcing ribs and a plurality of second reinforcing ribs. The plurality of first reinforcing ribs are arranged in parallel and spaced apart, and each is connected to a plurality of second reinforcing ribs. The plurality of second reinforcing ribs are arranged in parallel and spaced apart, and the first reinforcing ribs are perpendicular to the second reinforcing ribs. The main grid includes multiple first main grid bars and multiple second main grid bars. The multiple first main grid bars are arranged in parallel and spaced apart, and each is connected to multiple second main grid bars. The multiple second main grid bars are arranged in parallel and spaced apart, and the first main grid bars are perpendicular to the second main grid bars. The first reinforcing rib overlaps with the first main grille strip, and the width of the first main grille strip is greater than or equal to the width of the first reinforcing rib; the second reinforcing rib overlaps with the second main grille strip, and the width of the second main grille strip is greater than or equal to the width of the second reinforcing rib. This ensures that the first and second main grille strips can completely shield the first and second reinforcing ribs respectively, preventing the first and second reinforcing ribs from generating additional wind resistance to the airflow, increasing the airflow volume, and ensuring the airflow effect.

[0012] Furthermore, the housing assembly also includes an evaporator bracket, which is located inside the back panel. The evaporator bracket has ventilation openings, the positions of which correspond to the air inlet positions. Fixing ribs are installed within the ventilation openings, and these fixing ribs, reinforcing ribs, and main grille are sequentially overlapped. This allows for alignment during evaporator bracket installation, providing a foolproof function and improving installation efficiency. It also reduces the overall thickness of the fixing ribs, reinforcing ribs, and main grille after the evaporator bracket, back panel, and filter grille are assembled, increasing the structural compactness of the housing assembly and thus reducing its space requirements. Finally, it effectively reduces wind resistance, increases airflow, and ensures optimal air intake performance.

[0013] Secondly, this utility model provides an air conditioner, including an evaporator, an air outlet assembly, and the aforementioned housing assembly. The housing assembly includes a back panel, a filter grille, and a latch. The back panel has an air inlet. The evaporator and air outlet assembly are both installed on the inner side of the back panel, corresponding to the position of the air inlet.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] First Embodiment Please refer to the reference. Figures 1 to 4 This utility model provides a housing assembly 100 for shielding and protecting internal components of an air conditioner. It enables quick assembly and disassembly of the filter grille 120, facilitating cleaning and maintenance of the filter grille 120, simplifying assembly and disassembly steps, saving time and effort, improving assembly and disassembly efficiency, enhancing cleaning and maintenance efficiency, and improving user experience.

[0018] It should be noted that the housing assembly 100 is used in air conditioning cabinet units. The air conditioning cabinet unit is placed on the ground and can blow hot or cold air into the room to achieve heating or cooling functions. The housing assembly 100 is used to cover and protect the components inside the air conditioning cabinet unit to improve the aesthetics of the air conditioning cabinet unit.

[0019] The housing assembly 100 includes a back panel 110, a filter grille 120, and a latch 130. The back panel 110 has an air inlet 111 for allowing outside air to flow into it, thus facilitating the air intake function of the air conditioner and enabling its heat exchange function. The filter grille 120 is attached to the outside of the back panel 110 and covers the air inlet 111. The filter grille 120 filters the outside air flowing into the air inlet 111 to improve the cleanliness of the incoming airflow. The filter grille 120 has a guide groove 121, and the back panel 110 has a mating structure 112. The latch 130 slides in conjunction with the guide groove 121, and is used to lock or unlock itself from the mating structure 112 when sliding relative to the guide groove 121. Specifically, when the latch 130 is locked in place with the mating structure 112, the latch 130 can fix the relative position of the filter grille 120 and the back plate 110, preventing the filter grille 120 from detaching from the back plate 110. When the latch 130 is unlocked and separated from the mating structure 112, the latch 130 no longer fixes the relative position of the filter grille 120 and the back plate 110. At this time, the user can quickly remove the filter grille 120 from the back plate 110, which is convenient and quick. In this way, the filter grille 120 can be quickly disassembled and assembled, which facilitates the cleaning or maintenance of the filter grille 120, simplifies the disassembly and assembly steps, saves time and effort, improves disassembly and assembly efficiency, improves cleaning and maintenance efficiency, and enhances the user experience.

[0020] The filter grille 120 includes a filter screen 122 and a grille body 123. The filter screen 122 is installed on the grille body 123, which is hooked onto a back plate 110. The grille body 123 is used to limit and fix the filter screen 122 and improve the structural strength of the entire filter grille 120. The filter screen 122 is used to filter the incoming airflow. Specifically, the filter screen 122 and the grille body 123 are separate. The filter screen 122 is inserted between the grille body 123 and the back plate 110. The grille body 123 and the back plate 110 work together to limit the filter screen 122 and prevent it from falling off. In this way, the filter screen 122 and the grille body 123 can be disassembled and installed separately. If the filter screen 122 is to be cleaned without cleaning the grille body 123, it is not necessary to open the latch 130 or remove the grille body 123 from the back plate 110. The filter screen 122 can simply be pulled out from between the grille body 123 and the back plate 110, which further improves the cleaning and maintenance efficiency of the filter screen 122.

[0021] Furthermore, the grille body 123 is provided with a support beam 1231, and the filter screen 122 is disposed on the support beam 1231. The support beam 1231 is used to support the filter screen 122 to prevent the filter screen 122 from falling off. One end of the filter screen 122 is provided with a handle groove 1221, so that the user can manually pull out or insert the filter screen 122, which is convenient and practical.

[0022] In this embodiment, the filter screen 122 and the grille body 123 are separately disposed, with the filter screen 122 inserted between the grille body 123 and the back plate 110. However, this is not the only embodiment. In other embodiments, the filter screen 122 may be integrally formed with the grille body 123, or the filter screen 122 may be glued or snapped onto the grille body 123. The filter screen 122 may also be disposed on the side of the grille body 123 away from the back plate 110. The connection method between the filter screen 122 and the grille, as well as the placement position of the filter screen 122, are not specifically limited.

[0023] In this embodiment, there are two filters 122 and two support beams 1231. The two filters 122 are arranged sequentially along the height of the air conditioner unit, and each filter 122 is mounted on one support beam 1231. The two filters 122 together cover the air inlet 111 to achieve complete coverage of the air inlet 111 and ensure the filtering effect of the incoming airflow. However, this is not the only embodiment. In other embodiments, the number of filters 122 and support beams 1231 can be one or three. The number of filters 122 and support beams 1231 is not specifically limited.

[0024] The grille body 123 includes a grille section 1232, a first side plate 1233, a second side plate 1234, a top plate 1235, and a bottom plate 1236. The top plate 1235, the first side plate 1233, the bottom plate 1236, and the second side plate 1234 are connected end to end and together form an air passage cavity 1237. The position of the air passage cavity 1237 corresponds to the position of the air inlet 111, and the air passage cavity 1237 communicates with the air inlet 111, allowing the incoming airflow to enter the air inlet 111 through the air passage cavity 1237. Specifically, the grille section 1232 is disposed within the air passage cavity 1237 and is simultaneously connected to the top plate 1235, the first side plate 1233, the bottom plate 1236, and the second side plate 1234. The grille section 1232 is used to improve the connection strength of the top plate 1235, the first side plate 1233, the bottom plate 1236, and the second side plate 1234. A guide groove 121 is formed in the base plate 1236, meaning that the latch 130 is slidably mounted on the base plate 1236. The base plate 1236 can limit and guide the latch 130 through the cooperation between the latch 130 and the guide groove 121. The first side plate 1233 has a clearance opening 1238 for the filter screen 122 to pass through, so as to insert the filter screen 122 between the grille body 123 and the back plate 110, or to pull the filter screen 122 out from between the grille body 123 and the back plate 110.

[0025] Optionally, the first side plate 1233 is provided with a first hook 1239, the second side plate 1234 is provided with a second hook 1240, and the back plate 110 is provided with a first hooking groove 113 and a second hooking groove 114. The first hooking groove 113 and the second hooking groove 114 are arranged opposite to each other on both sides of the air inlet 111. The first hook 1239 is hooked to the first hooking groove 113, and the second hook 1240 is hooked to the second hooking groove 114. The first hook 1239 and the second hook 1240 work together to realize the hooking function of the first side plate 1233 and the second side plate 1234 at the same time, improve the balance of the grille body 123 hooked to the back plate 110, and prevent the grille body 123 from tilting or tipping over.

[0026] In this embodiment, there are five first hooks 1239, five second hooks 1240, five first hook slots 113, and five second hook slots 114. The five first hooks 1239 are arranged at intervals along the vertical direction, and each first hook 1239 is hooked to one first hook slot 113. The five second hooks 1240 are arranged at intervals along the vertical direction, and each second hook 1240 is hooked to one second hook slot 114. The five first hooks 1239 and five second hooks 1240 work together to further improve the balance and stability of the grille body 123 hooked to the back plate 110, and prevent the grille body 123 from accidentally detaching from the back plate 110. However, this is not the only embodiment. In other embodiments, the number of first hooks 1239, two hooks 1240, three first hook slots 113, and six second hook slots 114 are not specifically limited.

[0027] Optionally, the top plate 1235 is provided with a buckle 1241, and the back plate 110 has a slot 115. The slot 115 is located above the air inlet 111. The buckle 1241 engages with the slot 115. The back plate 110 can limit and fix the top plate 1235 through the engagement of the buckle 1241 and the slot 115, thereby fixing the relative position of the top plate 1235 and the back plate 110, and thus fixing the relative position of the grille body 123 and the back plate 110, preventing the grille body 123 from accidentally detaching from the back plate 110. Specifically, the buckle 1241 extends downward in the vertical direction, and the slot 115 is located at the top of the back plate 110, so that the buckle 1241 and the slot 115 can engage during the hanging of the grille body 123.

[0028] In this embodiment, there are three buckles 1241 and three slots 115. The three buckles 1241 are arranged sequentially at intervals along the extension direction of the top plate 1235. Each buckle 1241 engages with one slot 115. The three buckles 1241 work together to further improve the positioning effect between the grille body 123 and the back plate 110, preventing the grille body 123 from accidentally detaching from the back plate 110. However, this is not the only embodiment. In other embodiments, the number of buckles 1241 and slots 115 can be one or five. The number of buckles 1241 and slots 115 is not specifically limited.

[0029] Optionally, the base plate 1236 is provided with an insert 1242, and the back plate 110 has a slot 116 located below the air inlet 111. The insert 1242 is inserted into the slot 116. The back plate 110 can guide and limit the base plate 1236 through the insertion of the insert 1242 into the slot 116, thereby limiting the hanging direction of the grille body 123 and improving the stability of the grille body 123 hanging process. Specifically, the insert 1242 extends downward in the vertical direction to ensure that the grille body 123 can only be hung downwards, improving the stability and reliability of the hanging.

[0030] In this embodiment, there are two inserts 1242 and two slots 116. The two inserts 1242 are spaced apart along the extension direction of the base plate 1236, and each insert 1242 is inserted into one slot 116. The two inserts 1242 work together to further improve the guiding effect on the base plate 1236, thereby further improving the stability of the grid body 123 during the hanging process. However, this is not the only embodiment. In other embodiments, the number of inserts 1242 and slots 116 can be one or three. The number of inserts 1242 and slots 116 is not specifically limited.

[0031] Please refer to the reference. Figure 3 and Figure 5 In this embodiment, the mating structure 112 is a mating groove 1121. The mating groove 1121 is provided with a first sidewall 1122 and a second sidewall 1123. The first sidewall 1122 is provided with a limiting buckle 1125 protruding in the direction close to the second sidewall 1123. The limiting buckle 1125 is located at the opening 1124 of the mating groove 1121 and is spaced apart from the second sidewall 1123. The latch 130 extends into the mating groove 1121 and is used to engage or disengage with the limiting buckle 1125 to realize the locking or unlocking function of the filter grid 120. Specifically, the opening 1124 of the mating groove 1121 is located above it; when the latch 130 slides to abut against the first side wall 1122, the first side wall 1122 can limit the latch 130 to prevent the latch 130 from continuing to slide. At this time, the latch 130 abuts against the limiting buckle 1125, and the limiting buckle 1125 can limit the latch 130 to prevent the latch 130 from moving upward and dislodging from the opening 1124, thereby preventing the filter screen 120 from moving upward and maintaining the hanging of the filter screen 120. State: When the latch 130 slides to abut against the second side wall 1123, the second side wall 1123 can limit the latch 130 to prevent the latch 130 from continuing to slide. At this time, the latch 130 no longer cooperates with the limiting buckle 1125, and the limiting buckle 1125 no longer limits the latch 130. The latch 130 can move upward under the action of external force and disengage from the opening 1124. That is, the filter grid 120 can move upward under the action of external force and be released from the hook state, thereby realizing the disassembly function of the filter grid 120.

[0032] Please refer to the reference. Figure 3 and Figure 4 It should be noted that the back panel 110 is provided with a reinforcing mesh 117, which is located inside the air inlet 111. The reinforcing mesh 117 is used to improve the structural strength of the back panel 110. The mesh portion 1232 of the mesh body 123 in the filter mesh 120 includes a main mesh 1243 and multiple sub-mesh bars 1244. The multiple sub-mesh bars 1244 are spaced apart and are all connected to the main mesh 1243. The main mesh 1243 is used for main load-bearing, and the sub-mesh bars 1244 are used for auxiliary load-bearing. Specifically, the reinforcing mesh 117 overlaps with the main grille mesh 1243. Firstly, this allows for alignment during the installation of the filter grille 120, preventing mistaken installation and improving installation efficiency. Secondly, it reduces the overall thickness of the reinforcing mesh 117 and the main grille mesh 1243 after the back panel 110 and filter grille 120 are assembled, increasing the structural compactness of the housing assembly 100 and reducing its footprint. Thirdly, during the process of the incoming airflow flowing into the air inlet 111 through the air passage cavity 1237, the main grille mesh 1243 inevitably generates some air resistance. However, because the reinforcing mesh 117 overlaps with the main grille mesh 1243, the reinforcing mesh 117 will not generate additional air resistance, effectively reducing air resistance, increasing airflow, and ensuring the air intake effect.

[0033] Furthermore, the reinforcing mesh 117 includes a plurality of first reinforcing ribs 1171 and a plurality of second reinforcing ribs 1172. The plurality of first reinforcing ribs 1171 are arranged in parallel and spaced apart, and each is connected to the plurality of second reinforcing ribs 1172. The plurality of second reinforcing ribs 1172 are arranged in parallel and spaced apart, and the first reinforcing ribs 1171 are perpendicular to the second reinforcing ribs 1172. The main grid mesh 1243 includes a plurality of first main grid bars 1245 and a plurality of second main grid bars 1246. The plurality of first main grid bars 1245 are arranged in parallel and spaced apart, and each is connected to the plurality of second main grid bars 1246. The plurality of second main grid bars 1246 are arranged in parallel and spaced apart, and the first main grid bars 1245 are perpendicular to the second main grid bars 1246. The sub-grid bars 1244 are arranged in parallel with the first main grid bars 1245.

[0034] Specifically, the first reinforcing rib 1171 overlaps with the first main grille strip 1245, and the width of the first main grille strip 1245 is greater than or equal to the width of the first reinforcing rib 1171. This ensures that the first main grille strip 1245 can completely cover the first reinforcing rib 1171, preventing the first reinforcing rib 1171 from generating additional wind resistance to the airflow, increasing the airflow volume, and ensuring the airflow effect. Correspondingly, the second reinforcing rib 1172 overlaps with the second main grille strip 1246, and the width of the second main grille strip 1246 is greater than or equal to the width of the second reinforcing rib 1172. This ensures that the second main grille strip 1246 can completely cover the second reinforcing rib 1172, preventing the second reinforcing rib 1172 from generating additional wind resistance to the airflow, increasing the airflow volume, and ensuring the airflow effect.

[0035] Please refer to the reference. Figures 6 to 8 Optionally, the housing assembly 100 also includes an evaporator bracket 140 for mounting the evaporator 200. The evaporator bracket 140 is located inside the back panel 110 and has a vent 141. The position of the vent 141 corresponds to the position of the air inlet 111. The incoming airflow can pass through the air passage cavity 1237 and the air inlet 111 in sequence into the vent 141, and then pass through the evaporator 200. Specifically, a fixing rib mesh 142 is provided inside the vent 141. The fixing rib mesh 142 is used to improve the structural strength of the evaporator bracket 140. The fixing rib mesh 142, the reinforcing rib mesh 117, and the main grille mesh 1243 are arranged in sequence and overlapped. Firstly, it can be aligned during the installation of the evaporator bracket 140 to achieve a foolproof function and improve the installation efficiency of the evaporator bracket 140. Secondly, it can reduce the overall thickness of the fixing rib mesh 142, the reinforcing rib mesh 117, and the main grille mesh 1243 after the evaporator bracket 140, the back plate 110, and the filter grille 120 are assembled. Firstly, it improves the structural compactness of the housing assembly 100, thereby reducing the space occupied by the housing assembly 100. Secondly, during the process of the incoming airflow passing through the air passage cavity 1237 and the air inlet 111 into the ventilation opening 141, the main grille 1243 will inevitably generate a certain amount of wind resistance to the incoming airflow. During this process, since the fixed rib mesh 142, the reinforcing rib mesh 117 and the main grille 1243 are arranged to overlap in sequence, the reinforcing rib mesh 117 and the fixed rib mesh 142 will no longer generate additional wind resistance to the incoming airflow, thereby effectively reducing wind resistance, increasing air intake volume, and ensuring air intake effect.

[0036] It is worth noting that the fixed rib mesh 142, the reinforcing rib mesh 117, and the main grid mesh 1243 have the same density. However, because the main grid mesh 1243 is connected to sub-grid strips 1244, the density of the grid section 1232 (composed of the main grid mesh 1243 and the sub-grid strips 1244) is greater than that of the fixed rib mesh 142 and the reinforcing rib mesh 117. Specifically, because the fixed rib mesh 142 and the reinforcing rib mesh 117 have a lower density, after removing the filter grid 120 from the back plate 110, the user can directly pass through the air inlet 111 and the vent 141 to wipe the evaporator 200 without disassembling the back plate 110, which greatly improves the cleaning efficiency of the evaporator 200 and is convenient and quick.

[0037] Optionally, the back panel 110 includes a first back panel 118 and a second back panel 119. The first back panel 118 and the second back panel 119 are arranged sequentially along the height direction of the air conditioner unit, that is, the first back panel 118 and the second back panel 119 are set separately, with the first back panel 118 located above the second back panel 119, and the air inlet 111 is opened on the first back panel 118. In this way, the back panel 110 can be set separately, reducing the area of ​​a single back panel 110 (first back panel 118 or second back panel 119), avoiding deformation or even damage to the first back panel 118 or the second back panel 119 during transportation and installation, reducing the breakage rate and production costs.

[0038] The housing assembly 100 of this utility model embodiment has an air inlet 111 on a back plate 110. A filter grille 120 is attached to the outside of the back plate 110 and covers the air inlet 111. The filter grille 120 has a guide groove 121. The back plate 110 is provided with a mating structure 112. A latch 130 slides with the guide groove 121. The latch 130 is used to lock or unlock with the mating structure 112 when sliding relative to the guide groove 121. Compared with the prior art, the housing assembly 100 provided by this utility model, due to the use of the filter grille 120 attached to the outside of the back plate 110 and the latch 130 that selectively engages with the mating structure 112, can achieve quick assembly and disassembly of the filter grille 120, which is convenient for cleaning or maintenance. It simplifies the assembly and disassembly steps, saves time and effort, improves assembly and disassembly efficiency, improves cleaning and maintenance efficiency, and enhances user experience.

[0039] Second Embodiment Please refer to Figure 9 This utility model provides an air conditioner 10 for regulating indoor temperature. The air conditioner 10 includes a housing assembly 100, an evaporator 200, and an air outlet assembly 300. The basic structure, principle, and technical effects of the housing assembly 100 are the same as those in the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.

[0040] In this embodiment, the air conditioner 10 is a floor-standing air conditioner. The air conditioner 10 is placed on the ground and can blow hot or cold air into the room to achieve heating or cooling functions. The housing assembly 100 is used to shield and protect the components inside the air conditioner 10, improving the aesthetics of the floor-standing unit. Specifically, the evaporator 200 and the air outlet assembly 300 are both installed on the inner side of the back panel 110, corresponding to the position of the air inlet 111. The air outlet assembly 300 is located on the side of the evaporator 200 away from the back panel 110. The air outlet assembly 300 generates negative pressure, causing outside air to sequentially pass through the air passage cavity 1237 and the air inlet 111 into the vent 141, and then through the evaporator 200. The evaporator 200 is used to exchange heat with this portion of air to form a heat exchange airflow, thereby achieving heating or cooling functions.

[0041] The beneficial effects of the air conditioner 10 described in this embodiment are the same as those of the first embodiment, and will not be repeated here.

[0042] While the present invention has been disclosed above, it is not limited thereto.
