Description

Technical Field

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

[0002] An air conditioner, also known as an air conditioning unit, is a device that regulates indoor temperature. An air conditioner typically consists of an outdoor unit located outdoors and an indoor unit located indoors. The indoor unit's casing includes the outer shell and components such as the indoor heat exchanger and electrical control box housed within it.

[0003] To facilitate after-sales maintenance of components such as the indoor heat exchanger and electrical control box inside the casing, the indoor unit's casing typically includes a detachable cover and a base. Specifically, the rear end of the cover has a series of slots, and the base has corresponding clips. These clips engage with the slots to secure the cover to the base. However, when the indoor unit is installed against a wall, the space between the rear end of the cover and the base for removing the clips becomes narrow, making cover removal difficult. When after-sales maintenance requires removing the cover, personnel can only use force, which may damage the clips and prevent the cover from being reinstalled on the base. Furthermore, the slots on the cover also detract from its aesthetic appearance. Utility Model Content

[0004] Therefore, it is necessary to provide an air conditioning indoor unit and air conditioner that addresses the issue of how to improve the ease of disassembling and assembling the indoor unit's outer casing.

[0005] In a first aspect, this application provides an air conditioner indoor unit, comprising:

[0006] An indoor heat exchanger for exchanging heat with air;

[0007] The outer casing includes a base and an outer cover, the base and the outer cover together forming a cavity for accommodating the indoor heat exchanger, wherein:

[0008] The outer cover includes a front plate, a top plate connected to one side of the front plate, and a bottom plate connected to the other side of the front plate. The bottom plate has an air outlet, and the top plate has an air inlet. The air inlet is covered with a filter screen. The top plate is provided with a first filter screen guide rail for fixing the filter screen. The end of the first filter screen guide rail away from the front plate has a first insertion part protruding out, and the side of the first filter screen guide rail surface near the bottom plate has a first snap-fit ​​part protruding out.

[0009] The base connects the bottom plate and the top plate. The base has a first slot corresponding to the first insertion part. The first insertion part is inserted into the first slot to prevent the outer cover from detaching from the base along the width direction of the outer shell. The base has a first slot corresponding to the first snap-fit ​​part. The first snap-fit ​​part is inserted into the first slot to prevent the outer cover from detaching from the base along the thickness direction of the outer shell.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, the first plug portion has a first inclined surface on the side facing the top plate, and the first inclined surface is inclined away from the top plate along the direction in which the first plug portion protrudes from the first filter guide rail.

[0012] In one embodiment, the first snap-fit ​​portion has a second inclined surface on the side near the first plug-in portion, and the second inclined surface is inclined away from the first plug-in portion along the direction in which the first snap-fit ​​portion protrudes from the first filter guide rail.

[0013] In one embodiment, the top plate has multiple air inlets, which are spaced apart along the length of the outer cover. There are two first filter guide rails, arranged along the arrangement direction of the air inlets. One first filter guide rail is located outside the first air inlet, and the other first filter guide rail is located outside the last air inlet.

[0014] In one embodiment, there are two first filter guide rails, which are spaced apart on the top plate. A plurality of air inlets are provided between the two first filter guide rails, and the plurality of air inlets are spaced apart along the length of the outer cover.

[0015] In one embodiment, the base plate is provided with a third insertion part, and the base is provided with a third slot corresponding to the position of the third insertion part. The third insertion part is inserted into the third slot to prevent the outer cover from detaching from the base along the width direction of the outer shell.

[0016] In one embodiment, the base plate is provided with a second snap-fit ​​portion, and the base is provided with a second snap-fit ​​groove corresponding to the position of the second snap-fit ​​portion. The second snap-fit ​​portion is snapped into the second snap-fit ​​groove to prevent the outer cover from detaching from the base along the thickness direction of the outer shell.

[0017] In one embodiment, the base has a threaded hole; the front plate has a through hole that is aligned with the threaded hole; the housing also includes a threaded connector that passes through the through hole and is threadedly engaged with the threaded hole.

[0018] In one embodiment, the housing further includes a decorative panel that snaps into the front panel and covers the through-hole.

[0019] Secondly, the invention also provides an air conditioner, which includes the aforementioned indoor air conditioning unit.

[0020] In the aforementioned air conditioner indoor unit and air conditioner, a first insertion part protrudes from the end of the first filter guide rail of the outer cover away from the front panel, and a first snap-fit ​​part protrudes from the side of the first filter guide rail near the bottom plate. Simultaneously, a first slot is provided on the base corresponding to the first insertion part, and a first groove is provided on the base corresponding to the first snap-fit ​​part. Thus, by inserting the first insertion part into the first slot, the outer cover is prevented from detaching from the base along the width direction of the outer shell; by inserting the first snap-fit ​​part into the first groove, the outer cover is prevented from detaching from the base along the thickness direction of the outer shell, ensuring a stable connection between the top plate of the outer cover and the base. When the outer cover needs to be disassembled for after-sales maintenance, simply pull the first filter guide rail of the outer cover outward along the width direction of the outer cover. This deformation of the first filter guide rail will disengage the first snap-fit ​​part from the first slot, thereby removing the restriction on the outer cover along the thickness direction of the outer cover. Then, lift the outer cover outward along the thickness direction of the outer cover to allow the first insertion part to exit the first slot, thus detaching the outer cover from the base. This improves the disassembly efficiency and reliability of the outer cover. At the same time, the first insertion part, the first snap-fit ​​part, the first slot, and the first slot are all hidden inside the outer cover, eliminating the need to cut grooves on the outer cover and preserving its appearance integrity, thus enhancing the overall aesthetics of the air conditioner indoor unit.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] See Figure 1 as well as Figure 2 One embodiment of an air conditioner indoor unit includes a housing 10 and an indoor heat exchanger 20 disposed within the housing 10. The indoor heat exchanger 20 is used for heat exchange with air to regulate indoor temperature. Exemplarily, the indoor heat exchanger 20 may include an evaporator, a fan, etc. Figure 3The outer casing 10 includes a base 12 and an outer cover 11. The base 12 and the outer cover 11 together enclose a cavity for housing the indoor heat exchanger 20, thereby protecting the indoor heat exchanger 20.

[0051] Further, see Figure 3 as well as Figure 4 The outer cover 11 includes a front panel 113, a bottom plate 111 connected to one side of the front panel 113, and a top plate 112 connected to the other side of the front panel. The bottom plate 111 has an air outlet 1111, and the top plate 112 has an air inlet 1121. The air inlet 1121 is covered with a filter screen 30, and the top plate 112 is also provided with a first filter guide rail 1122 for fixing the filter screen 30. Figure 5 The first filter guide rail 1122 has a first insertion part 1124 protruding from the end away from the front plate 113, and the first filter guide rail 1122 has a first snap-fit ​​part 1125 protruding from the side near the bottom plate 111.

[0052] See Figure 7 as well as Figure 8 The base 12 is positioned opposite the front plate 113 and connects the bottom plate 111 and the top plate 112. The base 12 has a first slot 121 corresponding to the first insertion part 1124. Figures 10 to 12 The first insertion part 1124 is inserted into the first slot 121 to prevent the outer cover 11 from disengaging from the base 12 along the width direction of the outer casing 10. The base 12 has a first slot 122 corresponding to the position of the first insertion part 1125, and the first insertion part 1125 is inserted into the first slot 122 to prevent the outer cover 11 from disengaging from the base 12 along the thickness direction of the outer casing 10. Here, "width direction of the outer casing 10" refers to the relative direction between the bottom plate 111 and the top plate 112, that is, the vertical direction of the indoor unit of the air conditioner. Figure 1 The direction indicated by the middle arrow Z; "the thickness direction of the outer casing 10" refers to the relative direction between the front panel 113 of the outer casing and the base 12, that is, the front-to-back direction of the indoor unit of the air conditioner. Figure 1 The direction indicated by the middle arrow Y.

[0053] In the aforementioned air conditioner indoor unit, a first insertion part 1124 protrudes from the end of the first filter guide rail 1122 away from the front panel 113, and a first snap-fit ​​part 1125 protrudes from the side of the first filter guide rail 1122 near the bottom plate 111. Simultaneously, a first slot 121 is provided on the base 12 corresponding to the first insertion part 1124, and a first slot 122 is provided on the base 12 corresponding to the first snap-fit ​​part 1125. Thus, by inserting the first insertion part 1124 into the first slot 121, the outer cover 11 is prevented from detaching from the base 12 along the width direction of the outer shell 10; by inserting the first snap-fit ​​part 1125 into the first slot 122, the outer cover 11 is prevented from detaching from the base 12 along the thickness direction of the outer shell 10, ensuring a stable connection between the top plate 112 of the outer cover 11 and the base 12. When the outer cover 11 needs to be disassembled for after-sales maintenance, simply pull the first filter guide rail 1122 of the outer cover 11 outward along the width direction of the outer shell 10 to deform the first filter guide rail 1122 so that the first snap-fit ​​part 1125 can disengage from the first slot 122. Then lift the outer cover 11 outward along the thickness direction of the outer shell 10 so that the first plug part 1124 can disengage from the first slot 121, thereby detaching the outer cover 11 from the base 12. This improves the disassembly efficiency and reliability of the outer cover 11. At the same time, the first plug part 1124, the first snap-fit ​​part 1125, the first slot 121 and the first slot 122 are all hidden inside the outer shell 10, so there is no need to cut a groove in the top plate 112 of the outer cover 11, without damaging the appearance integrity of the outer cover 11, and improving the overall aesthetics of the air conditioner indoor unit.

[0054] For example, see Figure 12 In one embodiment, the first insertion part 1124 is a pin extending along the thickness direction of the outer cover 11, and the first slot 121 is opened at the rear end of the base 12. The extension direction of the first slot 121 is consistent with the extension direction of the first insertion part 1124. In this way, by inserting the first insertion part 1124 into the first slot 121, the outer cover 11 can be restricted from detaching from the base 12 along the width direction of the outer shell 10.

[0055] See also Figure 12 In one embodiment, the first insertion portion 1124 has a first inclined surface 1127 on the side facing the top plate 112, and the first inclined surface 1127 is inclined away from the top plate 112 along the direction in which the first insertion portion 1124 protrudes from the first filter guide rail 1122. The first inclined surface 1127 can reduce the thickness of the end of the first insertion portion 1124 away from the first filter guide rail 1122, making it easier for the first insertion portion 1124 to be inserted into the first slot 121. At the same time, when the outer cover 11 is installed onto the base 12 from top to bottom, if the relative position of the first insertion portion 1124 and the first slot 121 is slightly offset, the first inclined surface 1127 can guide the first insertion portion to gradually slide into the first slot 121, improving the convenience of installing the outer cover 11.

[0056] For example, see Figure 12 In one embodiment, the first latching portion 1125 is a latching platform extending along the width direction of the outer cover 11. The first latching groove 122 is formed at the rear end of the base 12, and the extending direction of the first latching groove 122 is consistent with the extending direction of the first latching portion 1125. Thus, by inserting the first latching portion 1125 into the first latching groove 122, the outer cover 11 can be prevented from disengaging from the base 12 along the thickness direction of the outer shell 10.

[0057] See also Figure 12 In one embodiment, the first snap-fit ​​portion 1125 has a second inclined surface 1128 on the side near the first insertion portion 1124, and the second inclined surface 1128 is inclined away from the first insertion portion 1124 along the direction in which the first snap-fit ​​portion 1125 protrudes from the first filter guide rail 1122. Thus, when the outer cover 11 is installed onto the base 12 from top to bottom, the first snap-fit ​​portion 1125 can be gradually squeezed into the first slot 122 along the second inclined surface 1128, preventing the first snap-fit ​​portion 1125 from breaking due to hard compression, and further improving the ease of installation of the outer cover 11.

[0058] See Figure 4 In one embodiment, there are two first filter guide rails 1122, which are spaced apart along the length of the outer cover 11 on the top plate 112. Multiple air inlets 1121, such as two, three, four, or more, are provided between the two first filter guide rails 1122. The multiple air inlets 1121 are arranged spaced apart along the length of the outer cover 11, wherein the length of the outer cover 11 is... Figure 1 The arrow X is shown in the diagram. Further, in one embodiment, the number of filter screens 30 can be one, covering all air inlets 1121, with both sides of the filter screen 30 fixed to two first filter guide rails 1122. By opening multiple air inlets 1121 in the top plate 112 of the outer casing 11, the air intake volume can be increased, thereby improving the heat exchange efficiency of the indoor heat exchanger 20.

[0059] See also Figure 4 In one embodiment, a second filter guide rail 1123 for fixing the filter screen 30 is also provided between two adjacent air inlets 1121, combined with Figure 6 The bottom end of the second filter guide rail 1123 protrudes and is provided with a second insertion part 1126, which extends along the thickness direction of the outer cover 11. Figure 9 The base 12 is provided with a second slot 123 corresponding to the position of the second insertion part 1126, combined with Figure 13 as well as Figure 14The second insertion part 1126 is inserted into the second slot 123 to prevent the outer cover 11 from disengaging from the base 12 along the width direction of the outer shell 10. Specifically, in one embodiment, the number of filter screens 30 can be multiple, with each filter screen 30 correspondingly covering each air inlet 1121, and the two sides of the filter screen 30 are fixed by the first filter screen guide rail 1122 and / or the second filter screen guide rail 1123 on both sides of the air inlet 1121.

[0060] By setting a second filter guide rail 1123 between adjacent air inlets 1121, the fixing effect of the filter 30 can be improved. At the same time, by setting a second insertion part 1126 at the bottom of the second filter guide rail 1123, and inserting the second insertion part 1126 into the corresponding second slot 123 on the base 12, the fixing effect of the outer cover 11 can be further improved.

[0061] Furthermore, in one embodiment, the second filter guide rail 1123 may also be provided with the same first snap-fit ​​portion 1125 as the first filter guide rail 1122. By engaging the first snap-fit ​​portion 1125 on the second filter guide rail 1123 with the corresponding first slot 122 on the base 12, the fixing effect of the outer cover 11 can be further improved.

[0062] See Figure 17 as well as Figure 18 In one embodiment, the base plate 111 is provided with a third insertion part 1112, and the base 12 is provided with a third slot 124 corresponding to the position of the third insertion part 1112. Combined with... Figure 15 The third insertion part 1112 is inserted into the third slot 124 to prevent the outer cover 11 from disengaging from the base 12 along the width direction of the outer shell 10.

[0063] For example, the third insertion part 1112 is a pin extending along the thickness direction of the outer cover 11, and the third slot 124 is opened at the front end of the base 12. The extension direction of the third slot 124 is consistent with the extension direction of the third insertion part 1112. In this way, by inserting the third insertion part 1112 into the third slot 124, the outer cover 11 can be restricted from detaching from the base 12 along the width direction of the outer shell 10.

[0064] Furthermore, the base plate 111 is provided with a plurality of third plug-in portions 1112, which are spaced apart along the length of the outer cover 11. The base 12 is provided with a plurality of third slots 124, and by inserting the third plug-in portions 1112 into the third slots 124 one by one, the fixing effect of the outer cover 11 is improved.

[0065] See Figure 17 as well as Figure 18In one embodiment, the base plate 111 is provided with a second snap-fit ​​portion 1113, and the base 12 is provided with a second snap-fit ​​groove 125 corresponding to the position of the second snap-fit ​​portion 1113. The second snap-fit ​​portion 1113 is snapped into the second snap-fit ​​groove 125 to restrict the outer cover 11 from disengaging from the base 12 along the thickness direction of the outer shell 10.

[0066] Combination Figure 16 For example, the second latching portion 1113 includes a cylindrical portion, and the second latching groove 125 is an arcuate groove that matches the shape of the cylindrical portion. The central angle corresponding to the cross-section of the arcuate groove is greater than 180°. Thus, after the cylindrical portion is inserted into the second latching groove 125, the outer cover 11 is prevented from disengaging from the base 12 along the thickness direction of the outer shell 10. It is understood that in other embodiments, the second latching portion 1113 may also be in the form of a latching platform or a buckle, which is not limited here.

[0067] Furthermore, the base plate 111 is provided with a plurality of second snap-fit ​​parts 1113, which are spaced apart along the length of the outer cover 11. The base 12 is provided with a plurality of second slots 125, and by inserting the second snap-fit ​​parts 1113 into the second slots 125 one by one, the fixing effect of the outer cover 11 is improved.

[0068] Furthermore, the third plug-in part 1112 is located on the side of the air outlet 1111 away from the front plate 113 of the outer cover 11, and the second snap-fit ​​part 1113 is located on the side of the air outlet 1111 close to the front plate 113, which makes it easier to remove the bottom plate 111 of the outer cover 11 from the base 12.

[0069] See Figure 3 In one embodiment, the base 12 has a threaded hole 129. The front plate 113 has a through hole 1131 aligned with the threaded hole 129. The outer casing 10 also includes a threaded connector (not shown), which passes through the through hole 1131 and is threadedly engaged with the threaded hole 129. Using the threaded connector to connect the outer cover 11 and the base 12 enhances the fixing effect between the outer cover 11 and the base 12. Exemplarily, the threaded connector can be a screw.

[0070] Furthermore, the front plate 113 has multiple through holes 1131, which are spaced apart along the length of the outer cover 11. The base 12 has multiple threaded parts, and by inserting the threaded connectors one by one into each through hole 1131 and threaded hole 129, the fixing effect of the outer cover 11 and the base 12 is improved.

[0071] See also Figure 3In one embodiment, the outer casing 10 further includes a decorative panel 13, which is snap-fitted into the front panel 113 and covers the through hole 1131. Exemplarily, the decorative panel 13 is snap-fitted into the front panel 113 by a snap fastener. By covering the through hole 1131 with the decorative panel 13, the through hole 1131 and the threaded connector can be hidden under the decorative panel 13, thereby ensuring the integrity of the appearance of the outer casing 10 and improving its aesthetics.

[0072] Furthermore, the front panel 113 also has a perforated opening 1132 communicating with the air inlet 1121. The first filter guide rail 1122 and the second filter guide rail 1123 extend to the front panel 113, and the filter 30 covers the perforated opening 1132. By opening the perforated opening 1132 in the front panel 113, the heat dissipation effect of the indoor heat exchanger 20 can be improved, while reducing the material cost of the front panel 113. By covering the perforated opening 1132 with the filter 30, impurities can be prevented from entering the indoor heat exchanger 20 through the perforated opening 1132. Furthermore, the decorative panel 13 also covers the perforated opening 1132, thereby ensuring the integrity of the appearance of the outer casing 10 and improving its aesthetics.

[0073] This application also provides an air conditioner, specifically, the air conditioner includes the indoor unit of any of the above embodiments. Further, the air conditioner may also include an outdoor unit (as shown in the figure), which is used to cool or heat the air before sending it into the indoor unit.

[0074] In the aforementioned air conditioner, the indoor unit features a first insertion part 1124 protruding from the end of the first filter guide rail 1122 of the outer casing 11 away from the front panel 113, and a first snap-fit ​​part 1125 protruding from the side of the first filter guide rail 1122 near the base plate 111. Simultaneously, a first slot 121 is provided on the base 12 corresponding to the first insertion part 1124, and a first slot 122 is provided on the base 12 corresponding to the first snap-fit ​​part 1125. By inserting the first insertion part 1124 into the first slot 121, the outer casing 11 is prevented from detaching from the base 12 along the width direction of the outer casing 10; by inserting the first snap-fit ​​part 1125 into the first slot 122, the outer casing 11 is prevented from detaching from the base 12 along the thickness direction of the outer casing 10, ensuring a stable connection between the top plate 112 of the outer casing 11 and the base 12. When the outer cover 11 needs to be disassembled for after-sales maintenance, simply pull the first filter guide rail 1122 of the outer cover 11 outward along the width direction of the outer shell 10 to deform the first filter guide rail 1122 so that the first snap-fit ​​part 1125 can disengage from the first slot 122. Then lift the outer cover 11 upward along the thickness direction of the outer shell 10 to disengage the outer cover 11 from the base 12. This improves the disassembly efficiency and reliability of the outer cover 11. At the same time, the first insertion part 1124, the first snap-fit ​​part 1125, the first slot 121 and the first slot 122 are all hidden inside the outer shell 10. There is no need to cut a groove in the top plate 112 of the outer cover 11, which does not damage the appearance integrity of the outer cover 11 and improves the overall aesthetics of the air conditioner indoor unit.
