Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] An air conditioner indoor unit is a device installed indoors to cool or heat the room. When working, the indoor unit typically draws in 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 room.

[0003] Considering that when the indoor air is polluted, directly drawing indoor air into the indoor unit of the air conditioner through the air inlet may damage the components inside the indoor unit, the air inlet is usually equipped with an air inlet panel module, which filters the air through a filter screen.

[0004] After prolonged use, the filter screen of the air conditioning panel module needs to be replaced with a new one. However, the filter replacement work in related technologies is relatively cumbersome or the replacement is not installed securely, resulting in poor usability and durability of the air conditioning indoor unit. Utility Model Content

[0005] This application discloses an indoor air conditioning unit where the filter replacement is relatively simple and the installation is secure.

[0006] To achieve the above objectives, in a first aspect, this application discloses an indoor air conditioning unit, comprising:

[0007] The housing encloses an internal space, and the housing is provided with an air inlet and an air outlet communicating with the internal space.

[0008] A fan, which is disposed in the internal space, is used to draw air from outside the casing into the internal space through the air inlet;

[0009] A heat exchanger, disposed within the internal space, is used for heat exchange with the air drawn into the internal space; the fan is also used to blow the heat-exchanged air out of the internal space through the air outlet; and...

[0010] An air inlet panel module, the air inlet panel module covering the air inlet, including a filter assembly, the filter assembly including:

[0011] The filter housing has a filter window that communicates with the air inlet, and the filter housing is provided with a mounting groove and a snap-fit ​​part;

[0012] A filter screen is inserted into the mounting slot and snapped into the snap-fit ​​part so that the filter screen covers the filter screen window.

[0013] Because the filter screen is inserted into the mounting slot and snapped into the snap-fit ​​part, in addition to the mounting slot fixing and limiting the filter screen, allowing it to be installed more securely and precisely in the filter housing, the snap-fit ​​part also fixes and limits the filter screen. In other words, the snap-fit ​​part and the mounting slot can provide a dual fixing function, thereby better ensuring that the filter screen can be installed stably and securely in the filter housing, thus improving the durability of the air conditioner indoor unit.

[0014] Meanwhile, since the filter screen is inserted into the mounting slot and snapped into the snap-fit ​​part, when the filter screen needs to be replaced, simply disengage the old filter screen from the snap-fit ​​part, pull the old filter screen out of the mounting slot, and then insert the new filter screen into the mounting slot and snap it into the snap-fit ​​part to achieve the purpose of replacing the filter screen. The entire filter screen replacement work does not involve tightening screws or other cumbersome procedures, thus making the filter screen replacement work relatively simple, and consequently making the air conditioner indoor unit more user-friendly.

[0015] Secondly, this application discloses another type of air conditioner indoor unit, including:

[0016] The housing encloses an internal space, and the housing is provided with an air inlet and an air outlet communicating with the internal space.

[0017] A fan, which is disposed in the internal space, is used to draw air from outside the casing into the internal space through the air inlet;

[0018] A heat exchanger, disposed within the internal space, is used for heat exchange with the air drawn into the internal space; the fan is also used to blow the heat-exchanged air out of the internal space through the air outlet; and...

[0019] An air inlet panel module, the air inlet panel module covering the air inlet, including a filter assembly, the filter assembly including:

[0020] The filter housing has a filter window that communicates with the air inlet, and the filter housing is provided with a mounting groove and a snap-fit ​​part;

[0021] A filter screen, which covers the filter screen window, is installed in the mounting groove and snapped into the snap-fit ​​part, so that the filter screen is detachably disposed in the filter screen housing.

[0022] Because the filter screen is detachably mounted on the filter housing, it is very convenient to remove the filter screen from the filter housing for replacement when it needs to be replaced after a long period of use, without having to replace the entire filter assembly. This reduces replacement costs and consequently lowers the overall operating cost of the indoor air conditioning unit.

[0023] Optionally, the filter housing includes:

[0024] A frame, located at the air inlet, encloses and forms the filter window;

[0025] A fence, which is set in the frame and arranged within the filter window, wherein the filter is attached to the fence.

[0026] Since the fence is set in the frame and arranged inside the filter window, and the filter is attached to the fence, the fence can limit and fix the filter, so that the filter can be installed more securely and stably on the filter shell.

[0027] Optionally, the plane of the fence arrangement is parallel to the cross-section of the filter window.

[0028] Because the layout plane of the fence is parallel to the cross-section of the filter window, on the one hand, the fence can be arranged more regularly on the frame, and on the other hand, the outer contour size of the fence can be the same as the size of the filter window. With this setting, when the filter is laid flat on the fence along the layout plane, the filter can just fill the entire filter window. The structural design is very ingenious.

[0029] Optionally, the filter housing further includes:

[0030] A retaining wall is disposed on the frame and is spaced apart from the arrangement plane of the fence, and the gap between the retaining wall and the arrangement plane of the fence forms the mounting groove.

[0031] Since the installation groove is formed by the retaining wall and the fence, the fence can be cleverly used as the structure to form the installation groove. There is no need to add more structures to the filter shell to form the installation groove. Therefore, the cost of the filter shell can be reduced to a certain extent.

[0032] Optionally, the filter housing further includes:

[0033] The buckle is disposed on the frame and is spaced apart from the arrangement plane of the fence to form a buckle gap, the buckle gap being the snap-fit ​​portion.

[0034] Because a snap-fit ​​gap is formed between the buckle and the grid's arrangement plane, when the filter screen is located within this gap, the combined action of the buckle and the grid allows the filter screen to be securely engaged. The structural design is very simple. Simple structures typically offer advantages such as stable operation and low production costs; therefore, the production cost of the filter screen housing can be reduced while ensuring stable operation.

[0035] Optionally, there may be multiple buckles, which are spaced apart along the periphery of the frame.

[0036] Because multiple clips are spaced apart along the perimeter of the frame, multiple positions of the filter screen can be engaged by the clips, thus preventing the filter screen from warping in certain areas and resulting in better filtration performance of the filter assembly.

[0037] Optionally, the buckle and the mounting groove are arranged opposite each other along a first direction, which is parallel to the arrangement plane of the fence.

[0038] Since the buckle and the mounting groove are arranged opposite each other along the first direction, and the opposite ends are far apart from the adjacent ends, the opposite ends of the filter screen along the first direction can be fixed by the buckle and the mounting groove respectively, thus better preventing the filter screen from lifting up in parts.

[0039] On the other hand, by setting the buckle and the mounting groove opposite each other along the first direction, the buckle and the mounting groove can be far apart. This avoids interference between the fixing effect of the mounting groove on the filter and the snapping effect of the buckle on the filter during the installation or removal of the filter, making the installation and removal of the filter more convenient and quick.

[0040] Optionally, the buckle includes:

[0041] An extension section is disposed in the frame and extends along the arrangement plane away from the fence;

[0042] A snap-fit ​​section is provided at one end of the extension section away from the arrangement plane and extends toward the center of the filter window. The snap-fit ​​section is spaced apart from the arrangement plane of the fence to form the snap-fit ​​gap.

[0043] Since the extension section is located on the frame and extends in a direction away from the arrangement plane of the fence, and the snap-fit ​​section is located at the end of the extension section away from the arrangement plane and extends towards the center of the filter window, the extension section and the snap-fit ​​section can together form an "L" shaped structure. The structure is very simple and can reduce the cost of the snap-fit.

[0044] Optionally, a guide surface is provided on the side of the snap-fit ​​section facing away from the arrangement plane, and the guide surface is inclined towards the arrangement plane along the edge of the filter window to the middle of the filter window.

[0045] Because the guide surface is inclined towards the plane of arrangement along the direction from the edge of the filter window to the center of the filter window, when installing the filter screen to the filter screen housing, firstly, one end of the filter screen can be inserted into the mounting groove, and then the other end of the filter screen can be pushed along the direction close to the guide surface. When the other end of the filter screen abuts against the guide surface, the filter screen can undergo some slight deformation and slide very smoothly into the snap-fit ​​gap under the guidance of the guide surface, thus enabling the filter screen to be easily snapped into the snap-fit ​​gap.

[0046] Optionally, the snap-fit ​​segment is an elastic segment.

[0047] By making the snap-fit ​​section elastic, the snap-fit ​​section can deform according to the pressure from the filter screen during the snap-fit ​​process, which increases the inclination of the guide surface of the snap-fit ​​section, thus making it easier for the filter screen to snap into the snap-fit ​​gap.

[0048] Optionally, the air inlet panel module further includes:

[0049] A panel frame covers the air inlet, and a filter window communicating with the air inlet is provided on the panel frame. The filter assembly covers the filter window, and the filter window is communicating with the filter window.

[0050] When the air intake panel module also includes a panel holder, the panel holder can be used as a base for specifically mounting the filter assembly, making it easy to install the filter assembly into the housing.

[0051] Optionally, the panel frame and the housing form an insertion slot with an opening, the insertion slot extending in a first direction, and the filter screen housing being slidably inserted into the insertion slot through the opening along the extension direction of the insertion slot, so that the filter screen assembly slides to cover the filter window or is removed from the filter window.

[0052] Since the panel frame and the housing form an open insertion slot, when the filter screen housing slides along the extension direction of the insertion slot through the opening, the insertion slot guides the filter screen housing to slide more smoothly in the first direction. On the other hand, it also ensures the sliding accuracy of the filter screen housing, thereby better ensuring that the filter assembly can cover the filter window well.

[0053] Optionally, a first guide extending in the first direction is provided on the first groove wall of the insertion groove, and a second guide adapted to the first guide is provided on the side of the filter shell opposite to the first groove wall, and the second guide cooperates with the first guide.

[0054] Since the first guide extends along the first direction and the second guide cooperates with the first guide, under the guiding action of the second guide and the first guide, on the one hand, the filter assembly can slide more smoothly in the insertion slot along the first direction, and on the other hand, the running accuracy of the filter assembly can be guaranteed when it slides in the insertion slot.

[0055] Optionally, a first connector is provided on the panel frame, and a second connector is provided on the filter shell. When the filter assembly slides along the positive direction of the first direction to cover the filter window, the first connector is connected to the second connector.

[0056] By setting a first connector on the panel frame and a second connector on the filter housing, when the filter assembly slides in the positive direction of the first direction to cover the filter window, the first connector connects to the second connector, thereby ensuring that the filter assembly can maintain the state of covering the filter window. This can prevent the filter assembly from abnormally sliding off the filter window, which would cause the air intake panel module to fail to filter.

[0057] Compared with the prior art, the beneficial effects of this application are as follows:

[0058] In this application, since the filter screen is inserted into the mounting groove and snapped into the snap-fit ​​part, in addition to the mounting groove serving to fix and limit the filter screen, allowing the filter screen to be installed more securely and in a more precise position in the filter screen housing, the snap-fit ​​part also serves to fix and limit the filter screen. That is, the snap-fit ​​part and the mounting groove can play a dual fixing role, thereby better ensuring that the filter screen can be installed stably and securely in the filter screen housing, thus making the indoor unit of the air conditioner more durable.

[0059] Meanwhile, since the filter screen is inserted into the mounting slot and snapped into the snap-fit ​​part, when the filter screen needs to be replaced, simply disengage the old filter screen from the snap-fit ​​part, pull the old filter screen out of the mounting slot, and then insert the new filter screen into the mounting slot and snap it into the snap-fit ​​part to achieve the purpose of replacing the filter screen. The entire filter screen replacement work does not involve tightening screws or other cumbersome procedures, thus making the filter screen replacement work relatively simple, and consequently making the air conditioner indoor unit more user-friendly.

Unless otherwise stated, "a plurality of" means two or more.

[0086] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0087] When an air conditioner indoor unit is working, it typically draws indoor air into the unit 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 room.

[0088] Considering that when the indoor air is polluted, directly drawing indoor air into the indoor unit of the air conditioner through the air inlet may damage the components inside the indoor unit, the air inlet is usually equipped with an air inlet panel module, which filters the air through a filter screen.

[0089] After prolonged use, the filter of the air conditioning panel module needs to be replaced. However, the filter replacement work in related technologies is cumbersome or the replacement is not securely installed, resulting in poor usability and durability of the air conditioning indoor unit. In view of this, this application provides a new air conditioning indoor unit to solve the above problems.

[0090] Figure 1 This is a structural schematic diagram of an air conditioner indoor unit 100 provided in one embodiment of this application. Figure 2 yes Figure 1 See the exploded view of the indoor unit 100 of the air conditioner. Figure 1 and Figure 2 The indoor unit of the air conditioner 100 includes a casing 1, which encloses an internal space 10.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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. Figure 4 yes Figure 3 The air conditioner indoor unit 100 is shown in a cross-sectional view at position AA. The air conditioner indoor unit 100 also includes a fan 2, which is disposed in the internal space 10 and is used to draw air from outside the casing 1 into the internal space 10 through the air inlet 11.

[0100] The fan 2 can be cylindrical or other possible shapes, and this embodiment does not limit this.

[0101] Since the fan 2 can draw air from outside the casing 1 into the internal space 10 through the air inlet 11, it can prepare for subsequent heat exchange of the air in the internal space 10.

[0102] In some embodiments, please continue to see Figure 3 and Figure 4 The indoor unit 100 of the air conditioner also includes a heat exchanger 3, which is disposed in the internal space 10 and is used to exchange heat with the air drawn into the internal space 10. The fan 2 is also used to blow the heat-exchanged air out of the internal space 10 through the air outlet 12.

[0103] Since the heat exchanger 3 can exchange heat with the air drawn into the internal space 10, and since the fan 2 can blow the air after heat exchange out of the internal space 10 through the air outlet 12, the purpose of cooling or heating the room can be achieved when the air after heat exchange is blown out of the internal space 10 and enters the room.

[0104] In some embodiments, see Figure 1 and Figure 2 The indoor unit 100 of the air conditioner also includes an air inlet panel module 4, which covers the air inlet 11.

[0105] The shape of the air inlet panel module 4 can be rectangular, square or any other possible shape, as long as it can cover the air inlet 11. This embodiment does not limit this.

[0106] In some embodiments, see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the air inlet panel module 4 provided in one embodiment of this application. Figure 6 yes Figure 5 The diagram shows the structure of the air intake panel module 4 from another perspective. The air intake panel module 4 includes a filter assembly 41.

[0107] When the air inlet panel module 4 includes a filter assembly 41, the air inlet panel module 4 can have a filtering function.

[0108] Since the air inlet panel module 4 covers the air inlet 11, the air entering the indoor unit 100 through the air inlet 11 can be filtered out by the filter assembly 41, so that the components in the indoor unit 100 can be protected from the influence of polluted air, thereby making the indoor unit 100 more durable.

[0109] Figure 7yes Figure 6 An exploded view of the center air intake panel module 4. Figure 8 yes Figure 7 An exploded view of the middle filter assembly 41, see [reference]. Figure 7 and Figure 8 The filter assembly 41 includes a filter housing 411, on which a filter window 4111 communicating with the air inlet 11 is provided.

[0110] The shape of the filter window 4111 can be square, rectangle or other irregular shape, etc., and this embodiment does not limit it.

[0111] In some embodiments, see Figure 8 and Figure 9 , Figure 9 yes Figure 8 The diagram shows the structure of the filter housing 411 from another perspective. The filter housing 411 is provided with an installation groove 4112 and a snap-fit ​​part 4113.

[0112] The mounting groove 4112 and the snap-fit ​​part 4113 can be integrally formed with the filter shell 411 or they can be separate structures. This embodiment does not limit this.

[0113] In some embodiments, see Figure 7 and Figure 8 The filter assembly 41 also includes a filter screen 412, which is inserted into the mounting groove 4112 and snapped into the snap-fit ​​part 4113 so that the filter screen 412 covers the filter screen window 4111.

[0114] Since the filter screen 412 is inserted into the mounting groove 4112 and snapped into the snap-fit ​​part 4113, in addition to the mounting groove 4112 fixing and limiting the filter screen 412 so that the filter screen 412 can be installed more securely and in a more precise position on the filter screen housing 411, the snap-fit ​​part 4113 can also fix and limit the filter screen 412. That is, the snap-fit ​​part 4113 and the mounting groove 4112 can play a dual fixing role, thereby better ensuring that the filter screen 412 can be installed stably and securely on the filter screen housing 411, thus making the air conditioner indoor unit 100 more durable.

[0115] Meanwhile, since the filter screen 412 is inserted into the mounting slot 4112 and snapped into the snap-fit ​​part 4113, when the filter screen 412 needs to be replaced, simply disengage the old filter screen 412 from the snap-fit ​​part 4113, pull the old filter screen 412 out of the mounting slot 4112, and then insert the new filter screen 412 into the mounting slot 4112 and snap it into the snap-fit ​​part 4113 to achieve the purpose of replacing the filter screen 412. The entire filter screen 412 replacement process does not involve tightening screws or other cumbersome procedures, thus making the filter screen 412 replacement process relatively simple, and consequently making the air conditioner indoor unit 100 more user-friendly.

[0116] In some embodiments, see Figure 2 and Figure 4 The indoor unit 100 of the air conditioner includes: a casing 1, a fan 2, a heat exchanger 3, and an air inlet panel module 4. The casing 1 encloses an internal space 10, and the casing 1 is provided with an air inlet 11 and an air outlet 12 communicating with the internal space 10. The fan 2 is disposed in the internal space 10 and is used to draw air from outside the casing 1 into the internal space 10 through the air inlet 11. The heat exchanger 3 is disposed in the internal space 10 and is used to exchange heat with the air drawn into the internal space 10. The fan 2 is also used to blow the heat-exchanged air out of the internal space 10 through the air outlet 12. The air inlet panel module 4 covers the air inlet 11.

[0117] See Figure 7 , Figure 8 and Figure 9 The air inlet panel module 4 includes a filter assembly 41, which includes a filter housing 411 and a filter window 4111 communicating with the air inlet 11. The filter housing 411 is provided with a mounting groove 4112 and a snap-fit ​​part 4113. The filter 412 is inserted into the mounting groove 4112 and snap-fitted into the snap-fit ​​part 4113 so that the filter 412 covers the filter window 4111.

[0118] In this embodiment, since the filter screen 412 is inserted into the mounting groove 4112 and snapped into the snap-fit ​​part 4113, in addition to the mounting groove 4112 fixing and limiting the filter screen 412 so that the filter screen 412 can be installed more securely and in a more precise position on the filter screen housing 411, the snap-fit ​​part 4113 can also fix and limit the filter screen 412. That is, the snap-fit ​​part 4113 and the mounting groove 4112 can play a dual fixing role, thereby better ensuring that the filter screen 412 can be installed stably and securely on the filter screen housing 411, thus making the air conditioner indoor unit 100 more durable.

[0119] Meanwhile, since the filter screen 412 is inserted into the mounting slot 4112 and snapped into the snap-fit ​​part 4113, when the filter screen 412 needs to be replaced, simply disengage the old filter screen 412 from the snap-fit ​​part 4113, pull the old filter screen 412 out of the mounting slot 4112, and then insert the new filter screen 412 into the mounting slot 4112 and snap it into the snap-fit ​​part 4113 to achieve the purpose of replacing the filter screen 412. The entire filter screen 412 replacement process does not involve tightening screws or other cumbersome procedures, thus making the filter screen 412 replacement process relatively simple, and consequently making the air conditioner indoor unit 100 more user-friendly.

[0120] In some embodiments, see Figure 8 and Figure 9 The filter screen 412 covers the filter screen window 4111, is installed in the mounting groove 4112 and snapped into the snap-fit ​​part 4113, so that the filter screen 412 is detachably installed in the filter screen housing 411.

[0121] Since the filter screen 412 is detachably mounted on the filter housing 411, when the filter screen 412 needs to be replaced after a long period of use, it can be easily removed from the filter housing 411 for replacement without replacing the entire filter assembly 41. Therefore, the replacement cost can be reduced, thereby reducing the overall operating cost of the air conditioner indoor unit 100.

[0122] In some embodiments, see Figure 2 , Figure 8 and Figure 9 The filter housing 411 includes a frame 4114 and a grille 4115. The frame 4114 is located at the air inlet 11 and forms a filter window 4111. The grille 4115 is disposed in the frame 4114 and arranged inside the filter window 4111. The filter 412 is attached to the grille 4115.

[0123] Since the fence 4115 is set in the frame 4114 and arranged in the filter window 4111, and the filter 412 is attached to the fence 4115, the fence 4115 can limit and fix the filter 412, so that the filter 412 can be installed more securely and stably in the filter shell 411.

[0124] The shape of the frame 4114 can be rectangular, square, or irregular, etc., and this embodiment does not limit it.

[0125] In order to improve the filtration effect of the filter assembly 41, in some embodiments, the periphery of the filter 412 abuts against the inner wall of the frame 4114.

[0126] This design ensures that there are no gaps between the periphery of the filter screen 412 and the inner wall of the frame 4114, thus preventing air leakage and improving the filtration effect of the filter assembly 41.

[0127] Furthermore, to enhance the mechanical strength of the filter screen 412 and to ensure a smoother surface when the filter screen 412 abuts against the fence 4115, in some embodiments, see [reference needed]. Figure 10 , Figure 10 This is a schematic diagram of another filter screen 412 provided in an embodiment of this application. The filter screen 412 has a rigid edging 4121 around its perimeter.

[0128] This design has several advantages. First, it strengthens the mechanical strength of the filter screen 412. Second, it allows for a tighter fit between the periphery of the filter screen 412 and the inner wall of the frame 4114, resulting in better filtration of the filter assembly 41. Third, it prevents wrinkles from forming on the filter screen 412, ensuring a smoother fit when it comes into contact with the grille 4115.

[0129] In some embodiments, see Figure 8 The plane of the fence 4115 is parallel to the cross-section of the filter window 4111.

[0130] Since the arrangement plane of the fence 4115 is parallel to the cross-section of the filter window 4111, on the one hand, the arrangement of the fence 4115 on the frame 4114 can be relatively regular, and on the other hand, the outer contour size of the fence 4115 can be the same as the size of the filter window 4111. With this setting, when the filter 412 is laid flat on the fence 4115 along the arrangement plane of the fence 4115, the filter 412 can just fill the entire filter window 4111. The structural design is very ingenious.

[0131] In some embodiments, see Figure 9 The filter housing 411 also includes a retaining wall 4116, which is disposed on the frame 4114 and is spaced apart from the fence 4115. The gap between the arrangement planes of the retaining wall 4116 and the fence 4115 forms an installation groove 4112.

[0132] Since the mounting groove 4112 is formed by the retaining wall 4116 and the fence 4115, the fence 4115 can be cleverly used as the structure to form the mounting groove 4112. There is no need to add more structures to the filter shell 411 to form the mounting groove 4112. Therefore, the cost of the filter shell 411 can be reduced to a certain extent.

[0133] In order for the filter screen 412 to be stably inserted into the mounting slot 4112, the width of the gap between the aforementioned retaining wall 4116 and the fence 4115 can be the same as the thickness of the filter screen 412. In this way, the retaining wall 4116 and the fence 4115 can clamp the filter screen 412, thereby allowing the filter screen 412 to be stably inserted into the mounting slot 4112.

[0134] In some embodiments, see Figure 8 The filter housing 411 also includes a buckle 4117, which is disposed on the frame 4114 and is spaced apart from the arrangement plane of the fence 4115 to form a buckle gap 20, and the buckle gap 20 is a snap-fit ​​part 4113.

[0135] Because a snap-fit ​​gap 20 is formed between the arrangement planes of the snap fastener 4117 and the grille 4115, when the filter screen 412 is located in the snap-fit ​​gap 20, the filter screen 412 can be snapped into the snap-fit ​​gap 20 under the combined action of the snap fastener 4117 and the grille 4115. The structural design is very simple. Simple structures usually have the advantages of stable operation and low production cost. Therefore, the production cost of the filter screen housing 411 can be reduced while ensuring the stable operation of the filter screen housing 411.

[0136] In some embodiments, see Figure 8 There are multiple buckles 4117, which are spaced apart along the periphery of the frame 4114.

[0137] Since multiple clips 4117 are spaced apart along the periphery of the frame 4114, multiple positions of the filter screen 412 can be engaged by the clips 4117, thereby preventing the filter screen 412 from warping up in some areas, and thus improving the filtration effect of the filter assembly 41.

[0138] The number of clips 4117 can be four or five, etc., and this embodiment does not limit this.

[0139] In some embodiments, see Figure 8 and Figure 9 The buckle 4117 and the mounting groove 4112 are along the first direction ( Figure 8 The fence is set relative to the Z-axis direction, with the first direction parallel to the layout plane of the fence 4115.

[0140] Since the buckle 4117 and the mounting groove 4112 are arranged opposite each other along the first direction, and the opposite ends are far apart from the adjacent ends, on the one hand, the opposite ends of the filter screen 412 along the first direction can be fixed by the buckle 4117 and the mounting groove 4112 respectively, thereby better avoiding the situation of the filter screen 412 being partially lifted.

[0141] On the other hand, by making the buckle 4117 and the mounting groove 4112 opposite to each other along the first direction, the buckle 4117 and the mounting groove 4112 can be far apart. This avoids interference between the fixing effect of the mounting groove 4112 on the filter screen 412 and the snapping effect of the buckle 4117 on the filter screen 412 during the installation or removal of the filter screen 412, making the installation and removal of the filter screen 412 more convenient and quick.

[0142] There are multiple ways to implement the aforementioned buckle 4117. In one possible implementation, see [link to relevant documentation]. Figure 8 and Figure 11 , Figure 11 yes Figure 8 A partial enlarged view of position B shows that the buckle 4117 includes an extension section 4117a and a snap-fit ​​section 4117b, wherein the extension section 4117a is disposed on the frame 4114 and along the direction away from the arrangement plane of the fence 4115. Figure 11 Extending in the negative X-axis direction, the snap-fit ​​section 4117b is located at the end of the extension section 4117a furthest from the arrangement plane. Figure 11 The right end of the middle extension 4117a extends toward the middle of the filter window 4111, and the snap-fit ​​section 4117b is spaced apart from the arrangement plane of the fence 4115 to form a snap-fit ​​gap 20.

[0143] Since the extension section 4117a is located on the frame 4114 and extends in a direction away from the arrangement plane of the fence 4115, and the snap-fit ​​section 4117b is located at the end of the extension section 4117a away from the arrangement plane and extends toward the middle of the filter window 4111, the extension section 4117a and the snap-fit ​​section 4117b can together form an "L" shaped structure. The structure is very simple and can reduce the cost of the snap-fit ​​4117.

[0144] Of course, the buckle 4117 can also be implemented in other possible ways, and this embodiment does not limit it.

[0145] In order to facilitate easier snapping of the filter screen 412 into the snap-fit ​​gap 20 during the installation of the filter screen 412 into the filter screen housing 411, in some embodiments, see Figure 8 and Figure 11 A guide surface 4117c is provided on the side of the snap-fit ​​section 4117b facing away from the arrangement plane, extending along the edge of the filter window 4111 to the center of the filter window 4111. Figure 11 (In the negative direction of the Z-axis), the guide surface 4117c is inclined towards the direction of the arrangement plane.

[0146] Since the guide surface 4117c is inclined towards the arrangement plane along the direction from the edge of the filter window 4111 to the center of the filter window 4111, when installing the filter screen 412 to the filter screen housing 411, firstly, one end of the filter screen 412 ( Figure 8 The top end of the middle filter screen 412 is inserted into the mounting slot 4112, and then the other end of the filter screen 412 can be pushed along the direction close to the guide surface 4117c. Figure 8 (At the bottom of the middle filter screen 412), when the other end of the filter screen 412 abuts against the guide surface 4117c, the filter screen 412 can undergo some slight deformation and slide very smoothly into the snap-fit ​​gap 20 under the guidance of the guide surface 4117c, thereby enabling the filter screen 412 to be easily snapped into the snap-fit ​​gap 20.

[0147] Furthermore, in order to make it easier for the filter screen 412 to snap into the snap-fit ​​gap 20 during the installation of the filter screen 412 into the filter screen housing 411, in some embodiments, see... Figure 8 and Figure 11 The snap-fit ​​section 4117b is an elastic section.

[0148] By making the snap-fit ​​section 4117b an elastic section, the snap-fit ​​section 4117b can deform according to the pressure from the filter screen 412 during the snap-fit ​​process of snapping the filter screen 412 into the snap-fit ​​gap 20. This increases the inclination of the guide surface 4117c of the snap-fit ​​section 4117b, thereby making it easier for the filter screen 412 to snap into the snap-fit ​​gap 20.

[0149] In some embodiments, see Figure 2 , Figure 7 and 8 The air inlet panel module 4 also includes: a panel frame 42, which covers the air inlet 11. The panel frame 42 is provided with a filter window 421 that communicates with the air inlet 11. The filter assembly 41 covers the filter window 421 and the filter window 4111 communicates with the filter window 421.

[0150] Since the air inlet 11 is connected to the filter window 421, and since the filter window 4111 is connected to the filter window 421, the filter window 4111 can be connected to the air inlet 11. Since the filter 412 is installed at the filter window 4111, when the air outside the air conditioner indoor unit 100 enters the air conditioner indoor unit 100 through the filter window 4111, the filter window 421 and the air inlet 11 in sequence, the filter 412 can effectively filter the dirt in the air.

[0151] When the air intake panel module 4 also includes a panel bracket 42, the panel bracket 42 can be used as a base for specifically installing the filter assembly 41, making it easier to install the filter assembly 41 into the housing 1.

[0152] In some embodiments, see Figure 12 , Figure 12 yes Figure 1 An exploded view of an indoor unit 100 of an air conditioner shows that a panel frame 42 and a housing 1 enclose a slot 30 with an opening 301, the slot 30 extending along a first direction ( Figure 12 Extending along the Z-axis direction, the filter housing 411 is slidably inserted into the insertion slot 30 through the opening 301 along the extension direction of the insertion slot 30, so that the filter assembly 41 slides to cover the filter window 421 or is removed from the filter window 421.

[0153] Since the panel frame 42 and the housing 1 form an insertion groove 30 with an opening 301, when the filter screen shell 411 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 sliding of the filter screen shell 411 along the first direction can be made smoother, and on the other hand, the sliding accuracy of the filter screen shell 411 can be guaranteed, thereby better ensuring that the filter assembly 41 can cover the filter window 421 well.

[0154] Since the insertion slot 30 is formed by the panel frame 42 and the housing 1, the structure of the panel frame 42 and the housing 1 can be fully utilized without having to re-open the entire insertion slot 30 on the panel frame 42. Therefore, the processing cost of the insertion slot 30 can be reduced to a certain extent.

[0155] To ensure smoother sliding of the filter assembly 41 within the insertion slot 30 along the first direction, and to guarantee the operational accuracy of the filter assembly 41 during sliding within the insertion slot 30, in some embodiments, see [reference needed]. Figure 13 , Figure 13 yes Figure 2 An exploded view of the center air intake panel module 4, with the insertion slot 30 along the first direction ( Figure 13 A first guide member 3021 extending along a first direction is provided on the first groove wall 302 extending in the Z-axis direction. A second guide member 4118 adapted to the first guide member 3021 is provided on the side of the filter shell 411 opposite to the first groove wall 302. The second guide member 4118 guides and cooperates with the first guide member 3021.

[0156] Since the first guide member 3021 extends along the first direction and the second guide member 4118 guides and cooperates with the first guide member 3021, under the guiding action of the second guide member 4118 and the first guide member 3021, on the one hand, the filter assembly 41 can slide more smoothly in the insertion groove 30 along the first direction, and on the other hand, the running accuracy of the filter assembly 41 when sliding in the insertion groove 30 can also be guaranteed.

[0157] The second guide member 4118 and the first guide member 3021 can be implemented in various ways. In one possible implementation, see [link to relevant documentation]. Figure 13 One of the first guide member 3021 and the second guide member 4118 is a guide protrusion and the other is a guide groove.

[0158] In order to ensure that the filter assembly 41 remains in the state of covering the filter window 421 after it is inserted into the insertion slot 30 and covers the filter window 421, in some embodiments, see [reference needed]. Figure 13 A first connector 422 is provided on the panel frame 42, and a second connector 4119 is provided on the filter shell 411. When the filter assembly 41 slides along the positive direction of the first direction to cover the filter window 421, the first connector 422 is connected to the second connector 4119.

[0159] By providing a first connector 422 on the panel frame 42 and a second connector 4119 on the filter housing 411, when the filter assembly 41 slides in the positive direction of the first direction to cover the filter window 421, the first connector 422 is connected to the second connector 4119. This ensures that the filter assembly 41 can maintain the state of covering the filter window 421, thereby preventing the filter assembly 41 from abnormally sliding off the filter window 421 and causing the air intake panel module 4 to fail in its filtering function.

[0160] In one possible implementation, one of the first connector 422 and the second connector 4119 is a claw and the other is a self-locking push-button switch.

[0161] Since the self-locking push-button switch and the claw structure are simple and the technology is mature, the cost of the first connector 422 and the second connector 4119 can be reduced to a certain extent.

[0162] In another possible implementation, at least one of the first connector 422 and the second connector 4119 is a magnetic component, and the other is a magnetic component or a ferromagnetic metal component.

[0163] Since at least one of the first connector 422 and the second connector 4119 is a magnetic component and the other is a magnetic or ferromagnetic metal component, the first connector 422 and the second connector 4119 can be connected by magnetic attraction, which is very simple. Furthermore, since both magnetic and ferromagnetic metal components are relatively inexpensive, the cost of the first connector 422 and the second connector 4119 can be reduced.

[0164] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
