Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, in particular to an air conditioner indoor unit. BACKGROUND

[0002] The air conditioner indoor unit is a device installed indoors to cool or heat the indoor environment. When working, the air conditioner indoor unit usually sucks indoor air through the air inlet for heat exchange, and then blows the heat-exchanged air back into the room through the air outlet to achieve the purpose of cooling or heating the indoor environment.

[0003] Considering that when the indoor air is relatively dirty, directly sucking the indoor air into the air conditioner indoor unit through the air inlet may cause damage to the parts in the air conditioner indoor unit, therefore, an air inlet panel module is usually provided at the air inlet to filter the air.

[0004] However, after the air inlet panel module is provided, on the one hand, the work of installing and detaching the air inlet panel module to / from the air inlet is not convenient, and on the other hand, the filtering effect is not ideal. Invention content

[0005] The present application discloses an air conditioner indoor unit, which is convenient to install and detach, and has better filtering effect.

[0006] To achieve the above purpose, in a first aspect, the present application discloses an air conditioner indoor unit, comprising:

[0007] A cabinet is provided, which forms an internal space, and an air inlet and an air outlet are provided on the cabinet and communicate with the internal space. Threaded holes and a second clamping portion are also provided on the cabinet. The threaded holes are provided on the top side of the cabinet, and the second clamping portion is provided on the front side of the cabinet.

[0008] A fan is provided in the internal space, which is used to suck air outside the cabinet into the internal space through the air inlet.

[0009] A heat exchanger is provided in the internal space, which is used to heat exchange the air sucked into the internal space. The fan is also used to blow the heat-exchanged air out of the internal space through the air outlet.

[0010] An air inlet panel module is provided, which comprises:

[0011] A panel frame is provided at the air inlet, and mounting holes are provided on the panel frame and correspond to the threaded holes.

[0012] The panel frame is further provided with a first clamping part, and the first clamping part is arranged in position correspondence with the second clamping part.

[0013] The locking member is threadedly connected to the threaded hole through the mounting hole, and the first clamping part is clamped in the second clamping part, so that the panel frame covers the air inlet. The panel frame is further provided with a filter window communicating with the air inlet and the outside of the cabinet.

[0014] A filter screen assembly is arranged at the filter window and used for filtering the air entering the air inlet through the filter window.

[0015] The locking member is threadedly connected to the threaded hole through the mounting hole, and the first clamping part is clamped in the second clamping part, so that the panel frame covers the air inlet. The panel frame is further provided with a filter window communicating with the air inlet and the outside of the cabinet.

[0016] Therefore, the panel frame is installed on the cabinet by the combination of thread connection and clamping. The clamping has the characteristics of convenient installation and disassembly, and the thread connection has the characteristics of strong connection force and tight abutment of the panel frame on the cabinet. In this way, on the one hand, the air inlet panel module can be conveniently installed on or disassembled from the air inlet of the cabinet, and on the other hand, no gap is formed between the air inlet panel module and the cabinet. In other words, no air leakage occurs between the air inlet panel module and the cabinet. The air outside the cabinet only enters the internal space through the filter window and the air inlet, and does not enter the internal space through the gap between the air inlet panel module and the cabinet.

[0017] In addition, the filter screen assembly is arranged at the filter window, so that the air outside the cabinet can be filtered by the filter screen assembly when entering the internal space, thereby improving the filtering effect of the air conditioner indoor unit and prolonging the service life of each component in the internal space of the air conditioner indoor unit, so as to achieve the purpose of prolonging the service life of the air conditioner indoor unit.

[0018] In a second aspect, the application discloses another air conditioner indoor unit, which comprises:

[0019] An air inlet panel module comprises:

[0020] A panel frame is arranged at the air inlet and provided with a mounting hole arranged in position correspondence with the threaded hole.

[0021] The panel frame is further provided with a first clamping part, and the first clamping part is arranged in position correspondence with the second clamping part.

[0022] The locking member is screwed to the threaded hole through the mounting hole, and the first clamping portion is clamped to the second clamping portion, so that the panel frame abuts against the cabinet, and a filter window communicating the air inlet and the outside of the cabinet is further arranged on the panel frame.

[0023] A filter screen assembly is arranged at the filter window and abuts against the panel frame, and the filter screen assembly is used for filtering air.

[0024] Since the filter screen assembly is arranged at the filter window and abuts against the panel frame, no gap exists between the filter screen assembly and the panel frame, so that air outside the cabinet can only enter the air inlet through the filter window, and cannot enter the air inlet through the gap between the filter screen assembly and the panel frame, thereby improving the filtering effect of the air conditioner indoor unit.

[0025] Optionally, the panel frame comprises:

[0026] A fitting plate is arranged on a first surface of the cabinet provided with the air inlet, and the filter window is arranged on the fitting plate.

[0027] A lap plate is connected to the fitting plate and arranged on a second surface of the cabinet adjacent to the first surface.

[0028] Since the fitting plate is arranged on the first surface of the cabinet provided with the air inlet, and the lap plate is connected to the fitting plate and arranged on the second surface of the cabinet adjacent to the first surface, the lap plate and the fitting plate substantially form an "L" shape, so that the panel frame can abut against two different first and second surfaces of the cabinet. In this way, the abutting area between the entire panel frame and the cabinet is larger, thereby avoiding the air leakage between the air inlet panel module and the cabinet.

[0029] Optionally, a first positioning member is arranged on the lap plate, a second positioning member is arranged on the second surface, and the first positioning member and the second positioning member are positioned and matched.

[0030] Since the first positioning member and the second positioning member are positioned and matched, on the one hand, the installation precision of the air inlet panel module installed on the cabinet can be ensured, on the other hand, the air inlet panel module can be more stably and firmly installed on the cabinet, and on the other hand, the contact between the panel frame and the cabinet can be more closely.

[0031] Optionally, the first positioning member is a positioning protruding strip extending away from the fitting plate, and the second positioning member is a positioning groove matched with the positioning protruding strip.

[0032] When the first positioning member is a positioning protrusion and the second positioning member is a positioning groove, the lap joint plate can be prevented from rotating relative to the second surface, and the positional relationship between the lap joint plate and the second surface is more stable and the positioning precision is higher.

[0033] Optionally, the second surface is an upper surface of the cabinet.

[0034] When the second surface is an upper surface of the cabinet, when the lap joint plate of the panel frame is placed on the second surface, even if the panel frame and the cabinet have not been assembled, under the action of gravity, the lap joint plate can be directly placed on the second surface without falling off the cabinet. The cooperation between the lap joint plate and the second surface can play a pre-assembly role, and thus the installation of the panel frame on the cabinet is very simple and convenient.

[0035] Optionally, the mounting hole is arranged on the lap joint plate, and the first clamping portion is arranged on the abutting plate.

[0036] Since the mounting hole is arranged on the lap joint plate and the first clamping portion is arranged on the abutting plate, that is, the mounting hole and the first clamping portion are arranged at different positions of the panel frame. In this way, each position of the panel frame can be well connected to the cabinet, and thus each position of the panel frame can be well abutted to the cabinet, so that the local warping of the panel frame relative to the cabinet can be avoided.

[0037] In addition, by arranging the mounting hole on the lap joint plate and the first clamping portion on the abutting plate, when the panel frame is installed on the cabinet, the first clamping portion on the abutting plate can be clamped with the second clamping portion on the cabinet, and the lap joint plate can be placed on the second surface of the cabinet. Then, the locking member is screwed into the threaded hole through the mounting hole, and the panel frame can be installed on the cabinet, which is very convenient.

[0038] Optionally, the first clamping portion comprises:

[0039] an extension section arranged on the abutting plate and extending in a direction close to the cabinet; and

[0040] a clamping section connected to an end of the extension section away from the abutting plate and extending in a direction away from the lap joint plate, a clamping gap being formed between the clamping section and the abutting plate, and the second clamping portion being clamped in the clamping gap.

[0041] Since the extending segment is arranged on the abutting plate and extends in a direction close to the shell, the clamping segment is connected to an end of the extending segment far away from the abutting plate and extends in a direction away from the abutting plate, so that the first clamping part forms a structure similar to an "L" shape, and then the clamping segment and the abutting plate form a clamping seam, and when the panel frame needs to be clamped to the second clamping part of the shell through the first clamping part, first, the clamping seam can be aligned with the second clamping part, and then the panel frame is pushed in the extending direction of the clamping segment towards the second clamping part, so that the second clamping part is clamped to the clamping seam, and then the panel frame can be clamped to the second clamping part of the shell through the first clamping part, which is very convenient.

[0042] Optionally, the second clamping part is a retaining wall arranged on the shell, the retaining wall extends vertically upward, and the retaining wall is inserted into the clamping seam.

[0043] Since the retaining wall extends vertically upward, when the retaining wall needs to be inserted into the clamping seam, the panel frame only needs to be pushed in the vertically downward direction, and then the gravity of the panel frame itself can easily achieve the purpose of inserting the retaining wall into the clamping seam, which is very convenient and labor-saving.

[0044] Optionally, the number of mounting holes is multiple, and / or the number of first clamping parts is multiple.

[0045] In this way, multiple positions of the abutting plate can be clamped to the shell, and multiple positions of the abutting plate can also be locked to the shell, thereby avoiding the situation that the panel frame is locally raised relative to the shell.

[0046] Optionally, the filter screen assembly is detachably covered at the filter window.

[0047] By making the filter screen assembly detachably cover the filter window, when the filter screen assembly needs to be cleaned or replaced after a long time, the filter screen assembly can be easily detached from the filter window, which is very convenient and fast.

[0048] Optionally, the filter screen assembly is slidably arranged in the first direction on the panel frame, so that the filter screen assembly slides to cover the filter window or moves away from the filter window.

[0049] Since the filter screen assembly is slidably arranged in the first direction on the panel frame, when the filter screen assembly needs to be covered at the filter window or moved away from the filter window, the filter screen assembly can be pulled back and forth in the first direction, so that the filter screen assembly can be covered at the filter window or moved away from the filter window, on the one hand, the operation of personnel is facilitated, and on the other hand, the running accuracy can also be ensured.

[0050] Optionally, the panel frame and the cabinet enclose a plug-in slot with an opening, the plug-in slot extends along the first direction, and the filter screen assembly is slidably plugged into the plug-in slot along the extension direction of the plug-in slot through the opening, so that the filter screen assembly is slid to cover the filter window or moves away from the filter window.

[0051] Since the panel frame and the cabinet enclose the plug-in slot with the opening, when the filter screen assembly slides along the extension direction of the plug-in slot through the opening, under the guidance of the plug-in slot, on the one hand, the sliding of the filter screen assembly along the first direction is smoother, and on the other hand, the sliding precision of the filter screen assembly is ensured, so that the filter screen assembly can better cover the filter window.

[0052] Optionally, the first direction is a vertical direction, and the opening is located on the lower surface of the panel frame.

[0053] Since the opening is located on the lower surface of the panel frame, when the filter screen assembly needs to be plugged into the plug-in slot, it can be inserted from the bottom to the top, and when the filter screen assembly needs to be removed from the plug-in slot, it can be pulled out from the top to the bottom. This design conforms to ergonomics and can reduce the difficulty of replacing the filter screen assembly.

[0054] Optionally, a first guide extending along the first direction is arranged on a first slot wall of the plug-in slot extending along the first direction, a second guide matched with the first guide is arranged on the side of the filter screen assembly opposite to the first slot wall, and the second guide is in guiding cooperation with the first guide.

[0055] Since the first guide extends along the first direction and the second guide is in guiding cooperation with the first guide, under the guidance of the first guide and the second guide, on the one hand, the sliding of the filter screen assembly along the first direction in the plug-in slot is smoother, and on the other hand, the running precision of the filter screen assembly in the plug-in slot is ensured.

[0056] Optionally, one of the first guide and the second guide is a guide protrusion, and the other is a guide groove.

[0057] On the one hand, since the guide protrusion and the guide groove have simple structures, the structure of the air inlet panel module can be simplified, and the processing cost of the air inlet panel module can be reduced.

[0058] On the other hand, since the guide protrusion is plugged into the guide groove, the gap between the filter screen assembly and the first slot wall can be sealed to some extent, so that the air leakage in the gap between the filter screen assembly and the first slot wall can be avoided, and the filtering effect of the air inlet panel module is better.

[0059] Optionally, one of an insertion protrusion extending along the periphery of the insertion slot or an insertion recess is arranged on the second slot wall opposite to the insertion slot, and the other is arranged on the side of the filter screen assembly opposite to the second slot wall.

[0060] Since the insertion protrusion is inserted into the insertion recess, on the one hand, the cooperation between the insertion protrusion and the insertion recess can also seal the gap between the second slot wall and the filter screen assembly, so as to avoid the situation that the gap between the filter screen assembly and the second slot wall leaks air, and thus the filtering effect of the air inlet panel module can be better.

[0061] Optionally, a first connecting piece is arranged on the panel frame, a second connecting piece is arranged on the filter screen assembly, and when the filter screen assembly slides in the forward direction of the first direction to cover the filtering window, the first connecting piece is connected to the second connecting piece.

[0062] By arranging the first connecting piece on the panel frame and the second connecting piece on the filter screen assembly, when the filter screen assembly slides in the forward direction of the first direction to cover the filtering window, the first connecting piece is connected to the second connecting piece, so as to ensure that the filter screen assembly can maintain the state of covering the filtering window, and thus the situation that the filter screen assembly abnormally slides away from the filtering window to cause the filtering function of the air inlet panel module to fail can be avoided.

[0063] Optionally, when the filter screen assembly slides in the forward direction of the first direction to cover the filtering window, the first connecting piece is clamped to the second connecting piece to prevent the filter screen assembly from sliding in the reverse direction of the first direction.

[0064] When the filter screen assembly continues to slide in the forward direction of the first direction, the first connecting piece and the second connecting piece are disengaged from the clamping.

[0065] By pushing the filter screen assembly in the forward direction of the first direction, the filter screen assembly can be covered on the filtering window. In the case that the filter screen assembly covers the filtering window, by pressing the filter screen assembly in the forward direction of the first direction, the filter screen assembly can be detached from the filtering window, which is very convenient and fast.

[0066] Optionally, one of the first connecting piece and the second connecting piece is a clamping jaw, and the other is a self-locking press switch.

[0067] Since the self-locking press switch and the clamping jaw are simple in structure and mature in technology, the cost of the first connecting piece and the second connecting piece can be reduced to a certain extent.

[0068] Optionally, at least one of the first connecting member and the second connecting member is a magnetic member, the other is a magnetic member or a ferromagnetic metal member.

[0069] Since at least one of the first connecting member and the second connecting member is a magnetic member, the other is a magnetic member or a ferromagnetic metal member, the first connecting member and the second connecting member can be connected by magnetic attraction, which is very simple. Moreover, since the cost of the magnetic member and the ferromagnetic metal member is relatively low, the cost of the first connecting member and the second connecting member can be reduced.

[0070] Compared with the prior art, the beneficial effects of the present application are that:

[0071] In the present application, since the locking member is threadedly connected to the threaded hole through the mounting hole and the first clamping portion is clamped to the second clamping portion, and when the locking member is threadedly connected to the threaded hole through the mounting hole and the first clamping portion is clamped to the second clamping portion, the panel frame can be installed on the cabinet and can just cover the air inlet on the cabinet.

[0072] Therefore, the panel frame is installed on the cabinet by the combination of thread connection and clamping. Since clamping has the characteristics of convenient installation and disassembly, and thread connection has the characteristics of strong connection force and enabling the panel frame to tightly abut against the cabinet, on the one hand, the air inlet panel module can be conveniently installed on or disassembled from the air inlet of the cabinet, and on the other hand, no gap can occur between the air inlet panel module and the cabinet. In other words, no air leakage can occur between the air inlet panel module and the cabinet. The air outside the cabinet can only enter the internal space through the filter window and the air inlet, and cannot enter the internal space through the gap between the air inlet panel module and the cabinet.

[0073] Since the filter screen assembly is arranged at the filter window, the air outside the cabinet can be filtered by the filter screen assembly when entering the internal space, thereby improving the filtering effect of the air conditioner indoor unit, and prolonging the service life of each component in the internal space of the air conditioner indoor unit, so as to achieve the purpose of prolonging the service life of the air conditioner indoor unit.

[0102] Before explaining the technical solutions of the present application, the background art of the present application is explained.

[0103] The indoor unit of an air conditioner is a device installed indoors to cool or heat the indoor space. When the indoor unit of an air conditioner is working, it usually sucks the indoor air through the air inlet to exchange heat in the indoor unit of the air conditioner, and then blows the heat-exchanged air back to the indoor space through the air outlet to achieve the purpose of cooling or heating the indoor space.

[0104] Considering that when the indoor air is relatively dirty, for example, in a kitchen scenario, directly sucking the indoor air into the indoor unit of the air conditioner through the air inlet may cause damage to the parts in the indoor unit of the air conditioner, therefore, an air inlet panel module is usually provided at the air inlet to filter the air.

[0105] However, after the air inlet panel module is provided, on the one hand, the work of installing and detaching the air inlet panel module to and from the air inlet is not flexible enough, and on the other hand, the filtering effect is not ideal in use, therefore, the present application provides a new indoor unit of an air conditioner to solve the above problems.

[0106] The technical solutions of the present application will be explained in combination with specific embodiments and drawings.

[0107] Figure 1 is a structural schematic diagram of an indoor unit of an air conditioner 100 provided by an embodiment of the present application, Figure 2 is Figure 1 is an exploded view of the indoor unit of an air conditioner 100 in Figure 1 and Figure 2 The indoor unit of an air conditioner 100 includes a casing 1, and the casing 1 surrounds to form an internal space 10.

[0108] The housing 1 can be rectangular or cuboid in shape and made of plastic. Of course, the housing 1 can also be other possible shapes and other possible materials. This embodiment does not limit this.

[0109] The shape of the aforementioned internal space 10 can be a cuboid, a cube, or other irregular shapes, and this embodiment does not limit this.

[0110] When the casing 1 forms an internal space 10, the internal space 10 can be used to house various components of the air conditioner indoor unit 100, and can also be used as a place for heat exchange, providing structural protection for the normal operation of the air conditioner indoor unit 100.

[0111] In some embodiments, see Figure 1 and Figure 2 The housing 1 is provided with an air inlet 11 and an air outlet 12 that communicate with the internal space 10.

[0112] This configuration allows indoor air to enter the interior space 10 through the air inlet 11 for heat exchange. Air in the interior space 10 can also be exhausted through the air outlet 12, allowing the heat-exchanged air to be discharged.

[0113] The shapes of the air inlet 11 and the air outlet 12 can be rectangular, square or other irregular shapes, and this embodiment does not limit them.

[0114] It should be noted that, see Figure 1 and Figure 2 The aforementioned air inlet 11 can be located on the front surface of the housing 1. Figure 2 The right side of the housing 1) and the air outlet 12 can be located on the lower surface of the housing 1. Figure 1 (The lower side of the housing 1). Of course, the air inlet 11 can also be set on the lower surface of the housing 1 and the air outlet 12 can be set on the front surface of the housing 1. That is, the air inlet 11 and the air outlet 12 can be set at any position of the housing 1. This embodiment does not limit this.

[0115] It should also be noted that the front surface of the casing 1 refers to the side facing the user when the air conditioner indoor unit 100 is installed on the wall or ceiling, and the lower surface of the casing 1 refers to the side facing downwards when the air conditioner indoor unit 100 is installed on the wall or ceiling.

[0116] In some embodiments, see Figure 3 and Figure 4 , Figure 3 yes Figure 1 The structural diagram of the indoor air conditioner unit 100 with some parts omitted.

[0117] Wherein, the fan 2 can be cylindrical or other possible shapes, and the embodiment does not limit this.

[0118] Since the fan 2 can suck air outside the casing 1 into the internal space 10 through the air inlet 11, it can provide preparation for subsequent heat exchange of air in the internal space 10.

[0119] In some embodiments, please continue to refer to Figure 3 and Figure 4 , the air conditioner indoor unit 100 further comprises a heat exchanger 3, the heat exchanger 3 is arranged in the internal space 10, and is used for heat exchange of air sucked into the internal space 10, and the fan 2 is further used for blowing the heat-exchanged air out of the internal space 10 through the air outlet 12.

[0120] Since the heat exchanger 3 can heat exchange the air sucked into the internal space 10, and the fan 2 can blow the heat-exchanged air out of the internal space 10 through the air outlet 12, when the heat-exchanged air blows out of the internal space 10 into the room, the purpose of cooling or heating the room can be achieved.

[0121] In some embodiments, refer to Figure 1 and Figure 2 , the air conditioner indoor unit 100 further comprises an air inlet panel module 4, the air inlet panel module 4 comprises: a panel frame 41, the panel frame 41 is located at the air inlet 11.

[0122] Wherein, the shape of the panel frame 41 can be rectangular, square or any other possible shape, and the embodiment does not limit this.

[0123] In some embodiments, refer to Figure 2 , Figure 5 and Figure 6 , Figure 5 is Figure 2 a structural schematic view of the air inlet panel module 4 in Figure 6 is Figure 5Fig. 6 is a structural schematic view of the air inlet panel module 4 from another perspective, the panel frame 41 is provided with a mounting hole 411 and a first clamping portion 412, the casing 1 is provided with a threaded hole 15 and a second clamping portion 16, the casing 1 is also provided with a threaded hole 15 and a second clamping portion 16, the threaded hole 15 is arranged on the top side of the casing 1, the second clamping portion 16 is arranged on the front side of the casing 1, the mounting hole 411 is arranged in position corresponding to the threaded hole 15, and the first clamping portion 412 is arranged in position corresponding to the second clamping portion 16. The locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, so that the panel frame 41 covers the air inlet 11, and the panel frame 41 is also provided with a filter window 413 communicating with the air inlet 11 and the outside of the casing 1.

[0124] Since the locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, and when the locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, the panel frame 41 can be installed on the casing 1 and can just cover the air inlet 11 on the casing 1.

[0125] Therefore, the panel frame 41 is installed on the casing 1 by the combination of screwing and clamping. Since clamping has the characteristics of convenient installation and disassembly, and screwing has the characteristics of strong connection force and enabling the panel frame 41 to tightly abut against the casing 1, on the one hand, it can ensure that the air inlet panel module 4 is very convenient to install on or disassemble from the air inlet 11 of the casing 1, and on the other hand, it can also prevent gaps from occurring between the air inlet panel module 4 and the casing 1. In a popular way, there is no air leakage between the air inlet panel module 4 and the casing 1. The air outside the casing 1 only enters the internal space 10 through the filter window 413 and the air inlet 11, and will not enter the internal space 10 from the gap between the air inlet panel module 4 and the casing 1.

[0126] In addition, since the threaded hole 15 is arranged on the top side of the casing 1 and the second clamping portion 16 is arranged on the front side of the casing 1, the panel frame 41 can be fixed to different sides of the casing 1, on the one hand, it can make the panel frame 41 more stably fixed to the casing 1, and on the other hand, it can also well avoid the local lifting of the panel frame 41.

[0127] It should be noted that the top side of the casing 1 refers to the side of the casing 1 facing the ceiling when the air conditioner indoor unit 100 is installed indoors, and the front side of the casing 1 refers to the side of the casing 1 away from the vertically installed wall surface.

[0128] In some embodiments, referring to Figure 2 and Figure 5The air inlet panel module 4 further comprises a filter screen assembly 42, which is arranged at the filter window 413 and used to filter the air entering the air inlet 11 through the filter window 413.

[0129] Since the filter screen assembly 42 is arranged at the filter window 413, and since the air outside the casing 1 can only enter the internal space 10 through the filter window 413 and the air inlet 11, but cannot enter the internal space 10 from the gap between the air inlet panel module 4 and the casing 1, it can be ensured that the air outside the casing 1 is filtered by the filter screen assembly 42 when entering the internal space 10, thereby improving the filtering effect of the air conditioner indoor unit 100, and further prolonging the service life of each component in the internal space 10 of the air conditioner indoor unit 100, so as to achieve the purpose of prolonging the service life of the air conditioner indoor unit 100.

[0130] Since the air conditioner indoor unit 100 has a good filtering effect, when it is applied in a kitchen or other scene with heavy oil smoke and dirty indoor air, it can still be well adapted, so that the air conditioner indoor unit 100 has a wider application scene.

[0131] In some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , the air conditioner indoor unit 100 comprises a casing 1, a fan 2, a heat exchanger 3 and an air inlet panel module 4, wherein the casing 1 is arranged to form an internal space 10, the casing 1 is provided with an air inlet 11 and an air outlet 12 which communicate with the internal space 10, the fan 2 is arranged in the internal space 10 and used to suck the air outside the casing 1 into the internal space 10 through the air inlet 11, the heat exchanger 3 is arranged in the internal space 10 and used to heat exchange the air sucked into the internal space 10, and the fan 2 is further used to blow the heat-exchanged air out of the internal space 10 through the air outlet 12.

[0132] Among them, referring to Figure 2 and Figure 6 , the air inlet panel module 4 comprises a panel frame 41 and a filter screen assembly 42, wherein the panel frame 41 is located at the air inlet 11, the panel frame 41 is provided with a mounting hole 411 and a first clamping portion 412, the casing 1 is provided with a threaded hole 15 and a second clamping portion 16, the locking member 5 is threadedly connected to the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, so that the panel frame 41 covers the air inlet 11, and the panel frame 41 is further provided with a filter window 413 which communicates the air inlet 11 and the outside of the casing 1, and the filter screen assembly 42 is arranged at the filter window 413 and used to filter the air entering the air inlet 11 through the filter window 413.

[0133] In the embodiment, the locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, and the panel frame 41 is installed on the shell 1 and can just cover the air inlet 11 on the shell 1 when the locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16.

[0134] Therefore, the panel frame 41 is installed on the shell 1 by the combination of screwing and clamping. The clamping has the characteristics of convenient installation and disassembly, and the screwing has the characteristics of strong connection force and enabling the panel frame 41 to tightly abut against the shell 1. In this way, on the one hand, the air inlet panel module 4 can be very conveniently installed at or disassembled from the air inlet 11 of the shell 1, and on the other hand, no gap can occur between the air inlet panel module 4 and the shell 1. In a popular way, no air leakage can occur between the air inlet panel module 4 and the shell 1. The air outside the shell 1 can only enter the internal space 10 through the filter window 413 and the air inlet 11, and cannot enter the internal space 10 from the gap between the air inlet panel module 4 and the shell 1.

[0135] In addition, the filter screen assembly 42 is arranged at the filter window 413, so that the air outside the shell 1 can be filtered by the filter screen assembly 42 when entering the internal space 10, thereby improving the filtering effect of the air conditioner indoor unit 100 and prolonging the service life of each component in the internal space 10 of the air conditioner indoor unit 100, so as to achieve the purpose of prolonging the service life of the air conditioner indoor unit 100.

[0136] In some embodiments, referring to Figure 1 and Figure 2 , the locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, so that the panel frame 41 abuts against the shell 1.

[0137] Since the panel frame 41 abuts against the shell 1 when the locking member 5 is screwed into the threaded hole 15 through the mounting hole 411 and the first clamping portion 412 is clamped to the second clamping portion 16, no gap will exist between the panel frame 41 and the shell 1. In this way, no air leakage can occur between the air inlet panel module 4 and the shell 1. The air outside the shell 1 can only enter the internal space 10 through the filter window 413 and the air inlet 11, and cannot enter the internal space 10 from the gap between the air inlet panel module 4 and the shell 1.

[0138] The locking member 5 can be a screw or other component capable of cooperating with the threaded hole 15 to install the panel frame 41 on the shell 1, which is not limited in the embodiment.

[0139] In some embodiments, referring to Figure 5 , the filter screen assembly 42 is arranged at the filter window 413 and abuts against the panel frame 41, and the filter screen assembly 42 is used for filtering air.

[0140] Since the filter screen assembly 42 is arranged at the filter window 413 and abuts against the panel frame 41, no gap is formed between the filter screen assembly 42 and the panel frame 41, so that it can be ensured that the air outside the casing 1 can only enter the air inlet 11 through the filter window 413, and the air cannot enter the air inlet 11 through the gap between the filter screen assembly 42 and the panel frame 41, so that the filtering effect of the air conditioner indoor unit 100 can be better.

[0141] In some embodiments, referring to Figure 2 and Figure 5 , the panel frame 41 comprises a fitting plate 414 and a lap plate 415, wherein the fitting plate 414 abuts against the first face 13 of the casing 1 where the air inlet 11 is arranged, and the filter window 413 is arranged on the fitting plate 414, and the lap plate 415 is connected to the fitting plate 414 and is arranged on the second face 14 of the casing 1 adjacent to the first face 13.

[0142] Since the fitting plate 414 abuts against the first face 13 of the casing 1 where the air inlet 11 is arranged, and the lap plate 415 is connected to the fitting plate 414 and is arranged on the second face 14 of the casing 1 adjacent to the first face 13, the lap plate 415 and the fitting plate 414 can form a substantially "L" shape, so that the panel frame 41 can abut against the two different first face 13 and second face 14 of the casing 1, respectively. In this way, the abutting area between the entire panel frame 41 and the casing 1 can be larger, so that the air leakage between the air inlet panel module 4 and the casing 1 can be better avoided.

[0143] In order to make the air inlet panel module 4 have higher installation precision when it is installed on the casing 1, in some embodiments, referring to Figure 2 and Figure 7 , Figure 7 is Figure 2 a structural schematic view of the air inlet panel module 4 in another view, the lap plate 415 is provided with a first positioning member 4151, the second face 14 is provided with a second positioning member 141, and the first positioning member 4151 and the second positioning member 141 are positioned and matched.

[0144] Since the first positioning component 4151 and the second positioning component 141 are positioned and cooperate, on the one hand, the installation accuracy of the air inlet panel module 4 when it is installed on the housing 1 can be guaranteed; on the other hand, the air inlet panel module 4 can be installed more stably and securely on the housing 1; and on the other hand, the contact between the panel frame 41 and the housing 1 can be made tighter to a certain extent.

[0145] The first positioning element 4151 and the second positioning element 141 can be implemented in various ways. For example, in one possible implementation, one of the first positioning element 4151 and the second positioning element 141 can be a positioning post and the other can be a positioning hole. Of course, the first positioning element 4151 and the second positioning element 141 can also have other possible structures. For example, in another possible implementation, see [link to relevant documentation]. Figure 2 and Figure 7 The first positioning element 4151 is along the direction away from the bonding plate 414. Figure 7 The positioning protrusion extends in the positive direction of the X-axis, and the second positioning element 141 is a positioning groove that is adapted to the positioning protrusion.

[0146] When the first positioning element 4151 is a positioning protrusion and the second positioning element 141 is a positioning groove, the overlapping plate 415 can be prevented from rotating relative to the second surface 14, thereby making the positional relationship between the overlapping plate 415 and the second surface 14 more stable and the positioning accuracy higher.

[0147] In this embodiment, the number of the first positioning element 4151 and the second positioning element 141 can both be one. Of course, the number of the first positioning element 4151 and the second positioning element 141 can also be other possible numbers, such as two or three, etc. This embodiment does not limit this.

[0148] In some embodiments, see Figure 2 The second side 14 is the upper surface of the casing 1.

[0149] When the second surface 14 is the upper surface of the housing 1, when the overlapping plate 415 of the panel frame 41 is placed on the second surface 14, even if the panel frame 41 and the housing 1 are not yet assembled, the overlapping plate 415 can be directly placed on the second surface 14 under the action of gravity without falling off the housing 1. The cooperation between the overlapping plate 415 and the second surface 14 can play a pre-assembly role, which makes it very simple and convenient to install the panel frame 41 on the housing 1.

[0150] In some embodiments, see Figure 2 Mounting hole 411 is provided on overlapping plate 415, and first snap-fit ​​part 412 is provided on bonding plate 414.

[0151] Since the mounting hole 411 is arranged on the overlapping plate 415, and the first clamping portion 412 is arranged on the abutting plate 414, that is, the mounting hole 411 and the first clamping portion 412 are arranged on different positions of the panel frame 41, in this way, each position of the panel frame 41 can be well connected with the shell 1, and each position of the panel frame 41 can be well abutted on the shell 1, so that the situation that the panel frame 41 is locally raised relative to the shell 1 can be avoided.

[0152] In addition, by arranging the mounting hole 411 on the overlapping plate 415 and the first clamping portion 412 on the abutting plate 414, when the panel frame 41 is installed on the shell 1, the first clamping portion 412 on the abutting plate 414 can be first clamped with the second clamping portion 16 on the shell 1, and the overlapping plate 415 is overlapped on the second surface 14 of the shell 1, then the locking piece 5 is screwed to the threaded hole 15 through the mounting hole 411, so that the panel frame 41 can be installed on the shell 1, which is very convenient.

[0153] In some embodiments, referring to Figure 2 and Figure 5 , the first clamping portion 412 comprises: an extending segment 4121 and a clamping segment 4122, wherein the extending segment 4121 is arranged on the abutting plate 414 and extends in a direction close to the shell 1 (the positive direction of the X-axis in the figure), and the clamping segment 4122 is connected to one end of the extending segment 4121 away from the abutting plate 414 (the left end of the extending segment 4121 in the figure) and extends in a direction away from the overlapping plate 415 (the positive direction of the Z-axis in the figure), and a clamping gap 20 is formed between the clamping segment 4122 and the abutting plate 414, and the second clamping portion 16 is clamped in the clamping gap 20. Figure 5 Figure 5 Figure 5 Since the extending segment 4121 is arranged on the abutting plate 414 and extends in a direction close to the shell 1, and the clamping segment 4122 is connected to one end of the extending segment 4121 away from the abutting plate 414 and extends in a direction away from the overlapping plate 415, the first clamping portion 412 forms a structure similar to an "L" shape, and the clamping gap 20 is formed between the clamping segment 4122 and the abutting plate 414, so that when the panel frame 41 needs to be clamped on the second clamping portion 16 of the shell 1 through the first clamping portion 412, first, the clamping gap 20 can be aligned with the second clamping portion 16, then the panel frame 41 is pushed in the extending direction of the clamping segment 4122 towards the direction close to the second clamping portion 16 (the positive direction of the Z-axis in the figure), so that the second clamping portion 16 can be clamped in the clamping gap 20, and the panel frame 41 can be clamped on the second clamping portion 16 of the shell 1 through the first clamping portion 412, which is very convenient.

[0154] Figure 2

[0155] ​​​​In some embodiments, referring to Figure 2 , the second clamping portion 16 is a retaining wall arranged on the shell 1, the retaining wall extends along the vertical upward (negative direction of the Z-axis) direction, and the retaining wall is inserted into the clamping seam 20. Figure 2

[0156] Since the retaining wall extends along the vertical upward direction, when it is necessary to insert the retaining wall into the clamping seam 20, the panel frame 41 only needs to be pushed in the vertical downward direction, and the gravity of the panel frame 41 itself can easily achieve the purpose of inserting the retaining wall into the clamping seam 20, which is very convenient and labor-saving.

[0157] In addition, after the retaining wall is inserted into the clamping seam 20, under the double actions of the clamping force between the retaining wall and the clamping seam 20 and the supporting force of the second surface 14 on the lap plate 415, the panel frame 41 can be stably pre-installed on the shell 1, thereby providing protection for subsequent locking of the panel frame 41 on the shell 1 by the locking member 5.

[0158] In order to better avoid the local warping of the panel frame 41 relative to the shell 1 after the panel frame 41 is installed on the shell 1, in some embodiments, referring to Figure 2 and Figure 6 , the number of the mounting holes 411 is multiple, and / or the number of the first clamping portions 412 is multiple.

[0159] In this way, multiple positions of the abutting plate 414 can be clamped on the shell 1, and multiple positions of the lap plate 415 can be locked on the shell 1, thereby avoiding the local warping of the panel frame 41 relative to the shell 1.

[0160] Specifically, the number of the mounting holes 411 can be three as shown in Figure 2 , of course, the number of the mounting holes 411 can also be two or four, and the like, which is not limited in the embodiment. The number of the first clamping portions 412 can be two as shown in Figure 6 , of course, the number of the first clamping portions 412 can also be three or four, and the like, which is not limited in the embodiment.

[0161] Considering that the filter screen assembly 42 needs to be disassembled and cleaned after a long time of use, in some embodiments, referring to Figure 2 , the filter screen assembly 42 is detachably covered at the filter window 413.

[0162] By allowing the filter screen assembly 42 to be detachably covered at the filter window 413, when the filter screen assembly 42 needs to be cleaned or replaced after a long time of use, the filter screen assembly 42 can be disassembled from the filter window 413, which is very convenient and fast.

[0163] ​In order to better protect the filter screen assembly 42 when the air conditioner indoor unit 100 is stopped, in some embodiments, referring to Figure 2 and Figure 8 , Figure 8 is another structure diagram of the air inlet panel module 4 provided by an embodiment of the present application. The filter window 413 is provided with a shielding plate 4131 which can be automatically opened and closed. In this way, when the air conditioner indoor unit 100 is stopped, the filter window 413 can be covered by closing the shielding plate 4131, which can not only protect the filter screen assembly 42, but also avoid the situation that small animals or other foreign matters enter the air conditioner indoor unit 100 and cause damage to the air conditioner indoor unit 100.

[0164] In some embodiments, the shielding plate 4131 is rotatably arranged at the filter window 413, and a motor is used to drive the shielding plate 4131 to rotate to achieve the purpose of opening or closing the filter window 413.

[0165] In some embodiments, referring to Figure 9 , Figure 9 is Figure 5 is an exploded view of the air inlet panel module 4 in Figure 9 , the filter screen assembly 42 is slidably arranged in the panel frame 41 along a first direction (Z-axis direction in

[0166] Since the filter screen assembly 42 is slidably arranged in the panel frame 41 along the first direction, when it is necessary to cover the filter screen assembly 42 at the filter window 413 or move it away from the filter window 413, it is only necessary to pull the filter screen assembly 42 back and forth along the first direction, so as to achieve the purpose of covering the filter screen assembly 42 at the filter window 413 or moving it away from the filter window 413, which not only facilitates the operation of personnel, but also ensures the accuracy of operation.

[0167] Among the above-mentioned implementation manners of the filter screen assembly 42 being slidably arranged in the panel frame 41 along the first direction, in one possible implementation manner, referring to Figure 9 and Figure 10 , Figure 10 is Figure 1 is an exploded view of the air conditioner indoor unit 100 in Figure 10 , the panel frame 41 and the casing 1 enclose a plug-in slot 30 having an opening 301, the plug-in slot 30 extends along a negative direction of the Z-axis in

[0168] Since the panel frame 41 and the housing 1 form an insertion groove 30 with an opening 301, when the filter assembly 42 slides along the extension direction of the insertion groove 30 through the opening 301, under the guiding action of the insertion groove 30, on the one hand, the filter assembly 42 can slide more smoothly along the first direction, and on the other hand, the sliding accuracy of the filter assembly 42 can be guaranteed, thereby better ensuring that the filter assembly 42 can cover the filter window 413 well.

[0169] Since the insertion slot 30 is formed by the panel frame 41 and the housing 1, the structure of the panel frame 41 and the housing 1 can be fully utilized without having to re-open the entire insertion slot 30 on the panel frame 41. Therefore, the processing cost of the insertion slot 30 can be reduced to a certain extent.

[0170] Considering that the indoor unit 100 of the air conditioner is usually installed in a high position, in order to make it easier to replace the filter assembly 42, in some embodiments, see Figure 10 First direction ( Figure 10 The Z-axis direction is vertical, and the opening 301 is located on the lower surface of the panel frame 41.

[0171] Since the opening 301 is located on the lower surface of the panel frame 41, when the filter assembly 42 needs to be inserted into the insertion slot 30, it can be inserted from bottom to top, and when the filter assembly 42 needs to be removed from the insertion slot 30, it can be pulled out from top to bottom. This design is ergonomic and can reduce the difficulty of replacing the filter assembly 42.

[0172] Of course, in other embodiments, the first direction can also be horizontal, and the opening 301 can also be located on the left or right side of the panel frame 41, etc. This embodiment does not limit this.

[0173] It should be noted that the lower surface of the panel frame 41 mentioned above refers to the downward-facing surface of the panel frame 41 when the air conditioner indoor unit 100 is installed on an indoor wall or ceiling. Similarly, the left and right sides of the panel frame 41 mentioned above also refer to the left and right sides of the panel frame 41 when the air conditioner indoor unit 100 is installed on an indoor wall or ceiling.

[0174] To ensure smoother sliding of the filter assembly 42 within the insertion slot 30 along the first direction, and to guarantee the operational accuracy of the filter assembly 42 during sliding within the insertion slot 30, in some embodiments, see [reference needed]. Figure 9 Insertion slot 30 along the first direction ( Figure 9The first guide 3021 extending along the first direction is arranged on the first slot wall 302 extending along the middle Z-axis direction, and the second guide 421 matched with the first guide 3021 is arranged on the side of the filter screen assembly 42 opposite to the first slot wall 302, and the second guide 421 is guided and matched with the first guide 3021.

[0175] Since the first guide 3021 extends along the first direction and the second guide 421 is guided and matched with the first guide 3021, under the guidance of the second guide 421 and the first guide 3021, on one hand, the sliding of the filter screen assembly 42 in the insertion slot 30 along the first direction is smoother, and on the other hand, the running accuracy of the filter screen assembly 42 in the insertion slot 30 is ensured.

[0176] The implementation mode of the second guide 421 and the first guide 3021 has multiple modes, in one possible implementation mode, referring to Figure 9 , one of the first guide 3021 and the second guide 421 is a guide convex strip, and the other is a guide concave groove.

[0177] On one hand, since the guide convex strip and the guide concave groove have simple structures, the structure of the air inlet panel module 4 can be simplified, and the processing cost of the air inlet panel module 4 is reduced.

[0178] On the other hand, since the guide convex strip is inserted into the guide concave groove, the gap between the filter screen assembly 42 and the first slot wall 302 can be sealed to some extent, so that the air leakage in the gap between the filter screen assembly 42 and the first slot wall 302 is avoided, and the filtering effect of the air inlet panel module 4 is better.

[0179] In some embodiments, referring to Figure 9 and Figure 11 , Figure 11 is Figure 9 the structural schematic view of the air inlet panel module 4 in another view, one of the insertion convex strip 422 extending along the periphery of the insertion slot 30 or the insertion concave groove 3031 is arranged on the second slot wall 303 opposite to the insertion slot 30, and the other is arranged on the side of the filter screen assembly 42 opposite to the second slot wall 303, and the insertion convex strip 422 is inserted into the insertion concave groove 3031.

[0180] Since the insertion convex strip 422 is inserted into the insertion concave groove 3031, on one hand, the gap between the second slot wall 303 and the filter screen assembly 42 can be sealed through the cooperation between the insertion convex strip 422 and the insertion concave groove 3031, so that the air leakage in the gap between the filter screen assembly 42 and the second slot wall 303 is avoided, and the filtering effect of the air inlet panel module 4 is better.

[0181] On the other hand, the cooperation between the inserted protrusion 422 and the inserted groove 3031 can also play a role in fixing and positioning, so that the filter assembly 42 can be more secure and more accurately positioned in the insertion slot 30.

[0182] Furthermore, in some embodiments, there can be multiple insertion grooves 3031, which are arranged parallel to each other on the second groove wall 303. Correspondingly, there can also be multiple insertion protrusions 422, which are also arranged parallel to each other. In this way, on the one hand, air leakage can be further avoided in the gap between the filter assembly 42 and the second groove wall 303, thereby further improving the filtration effect of the air inlet panel module 4. On the other hand, the filter assembly 42 can be more secure and more accurately positioned in the insertion slot 30.

[0183] In order to ensure that the filter assembly 42 remains in the state of covering the filter window 413 after it is inserted into the insertion slot 30 and covers the filter window 413, in some embodiments, see [reference needed]. Figure 9 A first connector 416 is provided on the panel frame 41, and a second connector 423 is provided on the filter assembly 42. The filter assembly 42 is aligned with the positive direction of the first direction. Figure 9 When the first connector 416 slides to cover the filter window 413 in the positive direction of the Z-axis, it connects to the second connector 423.

[0184] By providing a first connector 416 on the panel frame 41 and a second connector 423 on the filter assembly 42, when the filter assembly 42 slides in the positive direction of the first direction to cover the filter window 413, the first connector 416 is connected to the second connector 423. This ensures that the filter assembly 42 can maintain the state of covering the filter window 413, thereby preventing the filter assembly 42 from abnormally sliding off the filter window 413 and causing the air intake panel module 4 to fail in its filtering function.

[0185] In some embodiments, see Figure 9 and Figure 10 The filter assembly 42 is in the positive direction of the first direction ( Figure 9 When the filter assembly 42 slides in the negative direction of the Z-axis to cover the filter window 413, the first connector 416 engages with the second connector 423 to prevent the filter assembly 42 from moving in the reverse direction of the first direction. Figure 9 When the filter assembly 42 continues to slide in the positive direction of the first direction (Z-axis), the first connector 416 and the second connector 423 disengage.

[0186] In this way, when the filter screen assembly 42 needs to be covered on the filter window 413, the filter screen assembly 42 can be pushed along the positive direction of the first direction until the filter screen assembly 42 is covered on the filter window 413, and the first connecting piece 416 is clamped on the second connecting piece 423, so that the filter screen assembly 42 is prevented from sliding along the reverse direction of the first direction under the clamping of the first connecting piece 416 and the second connecting piece 423, thereby ensuring that the filter screen assembly 42 can keep the state of being covered on the filter window 413.

[0187] When the filter screen assembly 42 needs to be detached from the filter window 413, the filter screen assembly 42 can be continuously pressed along the positive direction of the first direction, so that the filter screen assembly 42 continuously slides along the positive direction of the first direction, and the first connecting piece 416 is disengaged from the second connecting piece 423. When the first connecting piece 416 is disengaged from the second connecting piece 423, the filter screen assembly 42 can be pulled along the negative direction of the first direction, so as to achieve the purpose of detaching the filter screen assembly 42 from the filter window 413.

[0188] It can be seen that the filter screen assembly 42 can be covered on the filter window 413 by pushing the filter screen assembly 42 along the positive direction of the first direction, and the filter screen assembly 42 can be detached from the filter window 413 by pressing the filter screen assembly 42 along the positive direction of the first direction when the filter screen assembly 42 is covered on the filter window 413, which is very convenient and fast.

[0189] In some embodiments, referring to Figure 9 , one of the first connecting piece 416 and the second connecting piece 423 is a clamping jaw, and the other is a self-locking press switch.

[0190] Since the self-locking press switch and the clamping jaw are simple in structure and mature in technology, the cost of the first connecting piece 416 and the second connecting piece 423 can be reduced to a certain extent.
