Description

Technical Field

[0001] This disclosure relates to the field of air conditioning equipment technology, and more particularly to indoor air conditioning units and air conditioners. Background Technology

[0002] In related technologies, in order to improve indoor air quality, a fresh air module is installed in the indoor unit of an air conditioner, which can introduce fresh outdoor air into the room.

[0003] The current fresh air modules have poor installation stability in air conditioner indoor units, which makes the air conditioner indoor units prone to noise during operation. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this disclosure provides an indoor air conditioning unit and an air conditioner, wherein the first opening can clamp the extension of the fresh air module, thereby improving the positional stability of the fresh air module and preventing noise caused by shaking between the fresh air module and the outer casing.

[0005] According to a first aspect of the present disclosure, an air conditioning indoor unit is provided, comprising:

[0006] The outer casing has a mounting cavity, and the first shell wall of the outer casing is provided with a first opening communicating with the mounting cavity;

[0007] A fresh air module is housed within the mounting cavity; the fresh air module has an extension section; at least a portion of the extension section is located at the first opening and communicates with the first opening, and the inner peripheral wall of the first opening abuts against and clamps the extension section.

[0008] According to a second aspect of the present disclosure, an air conditioner is provided, including the above-described indoor air conditioner unit.

[0009] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: When the extension section protrudes from the outer wall surface through the first opening, the inner peripheral wall of the first opening abuts against the outer peripheral wall of the extension section, causing the first opening to clamp the extension section, thereby improving the positional stability of the extension section and preventing noise caused by shaking between the extension section and the outer casing. Furthermore, since the extension section is part of the fresh air module, the improved positional stability of the extension section also improves the positional stability of the fresh air module installed in the indoor unit of the air conditioner, preventing noise caused by shaking of the fresh air module. In the indoor unit of the air conditioner of this disclosure, the clamping effect of the first opening on the extension section allows the first opening to limit the position of the fresh air module, thereby assisting in fixing the fresh air module. This improves the installation stability of the fresh air module in the mounting cavity with fewer fasteners, and the first opening is easy to process. Simultaneously, when installing the fresh air module, the extension section is first inserted into the first opening, which helps to pre-position the fresh air module, facilitating its positioning and installation in the mounting cavity.

[0010] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0031] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0032] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] To improve indoor air quality, related technologies include equipping indoor air conditioning units with fresh air modules that can introduce fresh outdoor air into the room.

[0034] However, the current fresh air modules have poor installation stability in air conditioner indoor units. Because the air conditioner indoor unit will vibrate when it is working, it is easy to generate noise.

[0035] In order to improve the installation stability of the fresh air module and reduce noise, conventional air conditioning indoor units usually use a large number of fasteners or a more complex fixing method, which makes the production and assembly of the overall air conditioning indoor unit more difficult.

[0036] This disclosure provides an indoor air conditioning unit and an air conditioner. In a configuration where an extension section protrudes from the outer wall through a first opening, the inner peripheral wall of the first opening abuts against the outer peripheral wall of the extension section. This clamping effect of the first opening on the extension section improves its positional stability and prevents noise caused by movement between the extension section and the outer casing. Furthermore, since the extension section is part of the fresh air module, the improved positional stability of the extension section also improves the positional stability of the fresh air module installed in the indoor air conditioning unit, preventing noise caused by movement of the fresh air module. In this embodiment, the clamping effect of the first opening on the extension section in the indoor air conditioning unit effectively limits the position of the fresh air module, thus assisting in its fixation. This improves the installation stability of the fresh air module in the mounting cavity with fewer fasteners, and the first opening is easy to manufacture. Simultaneously, during installation, the extension section is first inserted into the first opening, which helps to pre-position the fresh air module, facilitating its installation in the mounting cavity.

[0037] Firstly, see [the following] Figures 1-5 As shown in the present invention, an indoor air conditioner unit 10 is provided. The indoor air conditioner unit 10 is used in conjunction with an outdoor air conditioner unit to achieve the effect of cooling or heating the indoor space.

[0038] The indoor unit 10 of the air conditioner includes a housing 100, and the interior of the housing 100 has a mounting cavity 110. The mounting cavity 110 is used to install various components required for the operation of the indoor unit 10, such as the indoor unit fan, evaporator, and various fasteners. In order to improve indoor air quality, a fresh air module 20 is provided in the mounting cavity 110, so that when the indoor unit 10 is equipped with the fresh air module 20, it can not only cool or heat the room, but also introduce fresh outdoor air into the room.

[0039] The air conditioner indoor unit 10 of this embodiment includes a housing 100 comprising a first housing wall 120, the first housing wall 120 having an outer wall surface 121. After assembly, the outer wall surface 121 of the air conditioner indoor unit 10 is directly exposed to the environment. A control panel can also be installed on the housing 100 of the air conditioner indoor unit 10 of this embodiment to enable human-computer interaction between the air conditioner indoor unit 10 and the user.

[0040] See Figure 2 , Figure 3 and Figure 4 As shown, a first opening 122 is provided on the outer wall surface 121 of the first shell wall 120, and the first opening 122 communicates with the mounting cavity 110 inside the shell 100. See also Figure 3 and Figure 5 As shown, the fresh air module 20 has an extension section 210, and the extension section 210 is connected to the first opening 122; when the fresh air module 20 is in working condition, the fresh air module 20 can exhaust the extracted outdoor fresh air into the room through the extension section 210 and the first opening 122.

[0041] When the indoor unit 10 of the air conditioner is used indoors, a delivery pipe is connected to the outer casing 100. The delivery pipe is connected to the fresh air module 20 on one side and to the outside on the other side. So when the fresh air module 20 is working, the fresh air module 20 can draw in fresh air from the outside through the delivery pipe.

[0042] In this embodiment of the air conditioner indoor unit 10, a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, thereby enabling the fresh air module 20 to be made visible on the air conditioner indoor unit 10 of this embodiment.

[0043] Understandably, see Figure 3 and Figure 5As shown, the end of the extension 210 used to exhaust fresh air into the room forms an air outlet 211. Therefore, a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122; that is, at least a portion of the air outlet 211 protrudes from the outer wall surface 121. For example, the air outlet 211 passes through the first opening 122, and a portion of the air outlet 211 is located within the mounting cavity 110, while another portion protrudes from the outer wall surface 121. See also... Figure 8 As shown, part of the air outlet 211 is located within the first opening 122, and the other part protrudes from the outer wall surface 121; for example, see... Figures 2-3 and Figures 9-13 As shown, the air outlet 211 protrudes completely from the outer wall surface 121.

[0044] In the embodiment of the present disclosure, when a portion of the extension section 210 protrudes from the outer wall surface 121 through the first opening 122, the inner peripheral wall 122a of the first opening 122 abuts against the outer peripheral wall 212 of the extension section 210, thereby forming a clamping effect on the extension section 210.

[0045] Since the first opening 122 can clamp the extension section 210, it can improve the positional stability of the extension section 210 and prevent noise caused by shaking between the extension section 210 and the outer casing 100. Furthermore, since the extension section 210 is part of the fresh air module 20, the improved positional stability of the extension section 210 also improves the positional stability of the fresh air module 20 installed in the indoor air conditioning unit 10, preventing noise caused by shaking of the fresh air module 20.

[0046] It is worth mentioning that conventional air conditioner indoor units 10 typically employ a large number of fasteners or complex fixing methods to improve the installation stability of the fresh air module 20, which leads to greater difficulty in the production and assembly of the overall air conditioner indoor unit 10. In this embodiment, the air conditioner indoor unit 10 uses a first opening 122 to clamp the extension section 210, thereby limiting the position of the fresh air module 20 and assisting in its fixation. This improves the installation stability of the fresh air module 20 in the mounting cavity 110 with fewer fasteners, and the first opening 122 is easy to manufacture. Furthermore, when installing the fresh air module 20, the extension section 210 is first inserted into the first opening 122, which helps to pre-position the fresh air module 20, facilitating its installation in the mounting cavity 110.

[0047] In some embodiments of this disclosure, see Figure 7As shown, the inner peripheral wall 122a of the first opening 122 includes a first mating part 122b and a second mating part 122c, which are spaced apart in the circumferential direction of the first opening 122. When a portion of the extension segment 210 protrudes from the outer wall surface 121 through the first opening 122, the first mating part 122b and the second mating part 122c can respectively fit against different positions on the outer peripheral wall 212 of the extension segment 210, thereby enabling the first opening 122 to clamp the extension segment 210 through the first mating part 122b and the second mating part 122c, thus achieving auxiliary fixation of the fresh air module 20 in the mounting cavity 110 by the first opening 122.

[0048] In some embodiments of this disclosure, the extension 210 of the housing 200 extends toward the side where the first opening 122 is located, thereby allowing the extension 210 to pass through the first opening 122 and a portion of the extension 210 to protrude from the outer wall surface 121 through the first opening 122. In embodiments of this disclosure, along the extension direction perpendicular to the extension 210, that is, perpendicular to the depth direction X of the first opening 122, the positions of the first mating part 122b and the second mating part 122c are opposite to each other, such that the first mating part 122b and the second mating part 122c can respectively fit against the outer peripheral walls 212 on opposite sides of the extension 210.

[0049] Because the first mating part 122b and the second mating part 122c are positioned opposite each other, the first mating part 122b and the second mating part 122c can clamp the extension section 210 more stably, and the extension section 210 is less likely to slip off from the first mating part 122b and from the second mating part 122c.

[0050] In some cases, when the positions of the first mating part 122b and the second mating part 122c are not opposite, that is, when the line connecting the first mating part 122b and the second mating part 122c is not on the center line of the extension section 210, if the force of the first mating part 122b adhering to the outer peripheral wall 212 of the extension section 210 is large enough, and the force of the second mating part 122c adhering to the outer peripheral wall 212 of the extension section 210 is large enough, the first mating part 122b and the second mating part 122c can also achieve a clamping effect on the extension section 210.

[0051] In some embodiments of this disclosure, the first mating portion 122b and the outer peripheral wall 212 of the extension 210 can be in point contact, line contact, or surface contact. For example, see... Figure 7As shown, when the first mating part 122b is a protrusion protruding from the inner peripheral wall 122a of the first opening 122, if the side of the protrusion facing the extension is the tip of the protrusion, then the first mating part 122b and the outer peripheral wall 212 of the extension 210 are in point contact; if the side of the protrusion facing the extension is the side edge of the protrusion, then the first mating part 122b and the outer peripheral wall 212 of the extension 210 are in line contact; if the side of the protrusion facing the extension is the side surface of the protrusion, and the shape of the side surface matches the shape of the corresponding outer peripheral wall 212 of the extension 210, then the first mating part 122b and the outer peripheral wall 212 of the extension 210 are in surface contact.

[0052] Similarly, the second mating part 122c and the outer peripheral wall 212 of the extension 210 can be in point contact, line contact, or surface contact. For example, see Figure 7 As shown, when the second mating part 122c is a protrusion protruding from the inner peripheral wall 122a of the first opening 122, if the side of the protrusion facing the extension is the tip of the protrusion, then the second mating part 122c and the outer peripheral wall 212 of the extension 210 are in point contact; if the side of the protrusion facing the extension is the side edge of the protrusion, then the second mating part 122c and the outer peripheral wall 212 of the extension 210 are in line contact; if the side of the protrusion facing the extension is the side surface of the protrusion, and the shape of the side surface matches the shape of the corresponding outer peripheral wall 212 of the extension 210, then the second mating part 122c and the outer peripheral wall 212 of the extension 210 are in surface contact.

[0053] In this embodiment of the disclosure, see Figures 2-3 and Figures 8-13 As shown, the shape of the inner peripheral wall 122a of the first opening 122 matches the shape of the outer peripheral wall 212 of the extension. The first mating part 122b is a portion of the surface of the inner peripheral wall 122a of the first opening 122, and the second mating part 122c is also a portion of the surface of the inner peripheral wall 122a of the first opening 122. The first mating part 122b and the outer peripheral wall 212 of the extension 210, as well as the second mating part 122c and the outer peripheral wall 212 of the extension 210, are in surface contact. Since the frictional resistance of surface contact is greater, the clamping effect of the first opening 122 on the extension 210 is more stable, and the auxiliary fixing effect of the first opening 122 on the fresh air module 20 in the mounting cavity 110 is better.

[0054] In some embodiments of this disclosure, see Figures 2-3 and Figures 8-13As shown, the inner peripheral wall 122a of the first opening 122 fits snugly against the outer peripheral wall 212 of the extension segment 210. Since the inner peripheral wall 122a of the first opening 122 is annular, it can surround the extension segment 210, thereby improving the clamping effect of the first opening 122 on the extension segment 210 and preventing relative movement between the position of the extension segment 210 and the position of the first opening 122.

[0055] In some embodiments of this disclosure, see Figure 5 and Figure 6 As shown, the fresh air module 20 includes a housing 200, and the interior of the housing 200 has an inner cavity 220, in which a fan 221 is disposed. When the fresh air module 20 is in operation, the fan 221 rotates, and the fan 221 draws fresh outdoor air into the inner cavity 220 through the delivery pipe.

[0056] Furthermore, in the embodiments of this disclosure, see... Figure 2 and Figure 3 As shown, at least a portion of the housing 200 extends toward the direction of the first opening 122, thereby forming an extension section 210 on the housing 200. An air outlet 211 is provided at the end of the extension section 210 facing away from the inner cavity 220, connecting the air outlet 211 to the inner cavity 220. When the fresh air module 20 is in operation, the fan 221 rotates, thereby discharging fresh air from the inner cavity 220 into the room through the air outlet 211, thus optimizing the indoor air quality.

[0057] In some embodiments of this disclosure, see Figures 2-3 and Figures 5-6 As shown, the housing 200 of the fresh air module 20 includes a first sub-housing 201 and a second sub-housing 202, which are joined together to form the aforementioned inner cavity 220. In this embodiment, the first sub-housing 201 and the second sub-housing 202 are joined along a depth direction perpendicular to the first opening 122 to form a complete housing 200 of the fresh air module 20.

[0058] Furthermore, the first sub-shell 201 includes a portion of the structure with the extension 210, and the second sub-shell 202 also includes a portion of the structure with the extension 210. When the first sub-shell 201 and the second sub-shell 202 are assembled, the extension 210 of the shell 200 is also formed simultaneously.

[0059] Since the inner peripheral wall 122a of the first opening 122 fits the outer peripheral wall 212 of the extension 210, the first opening 122 in this embodiment of the present disclosure is also equivalent to fitting the first sub-shell 201 and the second sub-shell 202 respectively, so that the first opening 122 forms a holding effect on the extension 210 and also forms a clamping effect on the entire first sub-shell 201 and the second sub-shell 202.

[0060] It is worth mentioning that the first opening 122 further clamps the first sub-shell 201 and the second sub-shell 202 by clamping the extension section 210, so that the first opening 122 can help to achieve a fixed connection between the first sub-shell 201 and the second sub-shell 202, making the fixed connection between the first sub-shell 201 and the second sub-shell 202 after assembly more stable.

[0061] Understandably, see Figure 5 and Figure 6 As shown, after the first sub-shell 201 and the second sub-shell 202 are assembled, they will be fixedly connected by multiple fasteners 300, such as by bolts. The first opening 122 of this embodiment clamps the assembled first sub-shell 201 and the second sub-shell 202. Firstly, it can assist in positioning the first sub-shell 201 and the second sub-shell 202 before they are fixedly connected by multiple fasteners 300, thus avoiding relative movement between the first sub-shell 201 and the second sub-shell 202. This facilitates the connection and fixation between the first sub-shell 201 and the second sub-shell 202 by multiple fasteners 300, achieving the effect of easy assembly. Secondly, after the first sub-shell 201 and the second sub-shell 202 are connected and fixed by multiple fasteners 300, the first opening 122 can also assist the multiple fasteners 300 in fixing the first sub-shell 201 and the second sub-shell 202, thereby improving the stability of the connection and fixation between the first sub-shell 201 and the second sub-shell 202.

[0062] Since the first opening 122 can assist in fixing the assembly of the first sub-shell 201 and the second sub-shell 202, the first sub-shell 201 and the second sub-shell 202 can achieve a good connection and fixing effect with only a small number of fasteners 300 near the extension section 210. This allows the first opening 122 to improve the installation stability of the first sub-shell 201 and the second sub-shell 202 while reducing the assembly difficulty.

[0063] In some embodiments of this disclosure, as described above, the first sub-shell 201 and the second sub-shell 202 are fixedly connected by a plurality of fasteners 300 after being assembled.

[0064] For example, since the first opening 122 can fix the first sub-shell 201 and the second sub-shell 202 at the extension 210, multiple fasteners 300 can be distributed on the side of the shell 200 away from the first opening 122, so that the multiple fasteners 300 fix the part of the shell 200 that is far from the first opening 122. Thus, with the cooperation of the first opening 122 and the multiple fasteners 300, the splicing and fixing between the first sub-shell 201 and the second sub-shell 202 can be realized, thereby improving the structural stability of the shell 200.

[0065] In another example, the housing 200 is provided with a plurality of fasteners 300 in the portion near the first opening 122 and in the portion away from the first opening 122. The portion of the housing 200 near the first opening 122 is provided with a first number of fasteners 300, and the portion of the housing 200 away from the first opening 122 is provided with a second number of fasteners 300, wherein the first number is less than the second number.

[0066] As another example, the housing 200 is provided with a plurality of fasteners 300 in the portion near the first opening 122 and in the portion away from the first opening 122, wherein the distribution density of the plurality of fasteners 300 provided in the portion of the housing 200 near the first opening 122 is less than the distribution density of the plurality of fasteners 300 provided in the portion of the housing 200 away from the first opening 122.

[0067] It is understandable that, since the first opening 122 clamps the extension 210, the first opening 122 can play an auxiliary role in fixing the first sub-shell 201 and the second sub-shell 202 during assembly. Therefore, the use of fewer fasteners 300 on the shell 200 can make the connection and fixing effect between the first sub-shell 201 and the second sub-shell 202 better, thereby improving the structural stability of the shell 200.

[0068] In some embodiments of this disclosure, the first sub-shell 201 and the second sub-shell 202 are fixedly connected by fasteners 300. The fasteners 300 located near the first opening 122 are in a limiting fit with the first shell wall 120, thereby limiting the relative position of the shell 200 and the first shell wall 120 and improving the positional stability of the shell 200 in the mounting cavity 110.

[0069] In some embodiments of this disclosure, see Figure 2 , Figure 5 and Figure 6As shown, a limiting groove 123 is provided on the first shell wall 120. The fastener 300 located near the first opening 122 is embedded in the limiting groove 123, thereby restricting the movement of the shell 200 along the depth direction of the first opening 122. More specifically, it can restrict the movement of the shell 200 toward the inside of the mounting cavity 110 and restrict the movement of the shell 200 toward the outside of the first shell wall 120, thereby improving the installation stability of the fresh air module 20 in the mounting cavity 110.

[0070] Furthermore, through the optimized design of the limiting groove 123 and / or the fastener 300, the fastener 300 located near the first opening 122 is embedded in the limiting groove 123, which can also limit the relative movement of the housing 200 with the first housing wall 120 in the depth direction perpendicular to the first opening 122, thereby improving the installation stability of the fresh air module 20 in the mounting cavity 110.

[0071] In some embodiments of this disclosure, see Figure 9 As shown, a first buffer 124 is provided on the first shell wall 120. When part of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, the outer peripheral wall 212 of the extension 210 fits against the first buffer 124.

[0072] Furthermore, the first buffer 124 is a component with certain elastic properties, such as a rubber component or a spring component. Exemplarily, in this embodiment of the present disclosure, the first buffer 124 is a rubber component. The first buffer 124 is disposed on the first shell wall 120, and the outer peripheral wall 212 of the extension segment 210 is attached to the first buffer 124. Because the first buffer 124 has elastic properties, it can buffer the vibration between the first shell wall 120 and the extension segment 210, thereby improving the connection stability between the first shell wall 120 and the extension segment 210, and improving the clamping effect of the first opening 122 on the extension segment 210.

[0073] Furthermore, since the outer peripheral wall 212 of the extension 210 is attached to the first buffer member 124, the first buffer member 124 can exert a squeezing effect on the extension 210 under the action of its own elastic properties. This allows the first buffer member 124 and the inner peripheral wall 122a of the first opening 122 to also clamp the extension 210, thereby improving the positional stability between the first shell wall 120 and the extension 210, preventing the shell 200 from moving along the depth direction of the first opening 122, and preventing the shell 200 from moving along the depth direction perpendicular to the first opening 122.

[0074] In some embodiments of this disclosure, see Figure 10 and Figure 11As shown, a second buffer 212a is provided on the outer peripheral wall 212 of the extension 210. When a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, the first shell wall 120 fits against the second buffer 212a.

[0075] Furthermore, the second buffer 212a is a component with certain elastic properties, such as a rubber component or a spring component. Exemplarily, in this embodiment of the present disclosure, the second buffer 212a is a rubber component. The second buffer 212a is disposed on the outer peripheral wall 212 of the extension section 210, and the first shell wall 120 is attached to the second buffer 212a. Due to the elastic properties of the second buffer 212a, it can buffer the vibration between the first shell wall 120 and the extension section 210, thereby improving the connection stability between the first shell wall 120 and the extension section 210, and improving the clamping effect of the first opening 122 on the extension section 210.

[0076] It is worth mentioning that when the second buffer 212a is located within the mounting cavity 110, see Figure 11 As shown, the second buffer 212a can form a limiting effect with the first shell wall 120, thereby restricting the movement of the extension 210 toward the outside of the first shell wall 120, and thus restricting the movement of the shell 200 toward the outside of the first shell wall 120. See also Figure 10 As shown, when the second buffer 212a is located on the outer wall surface 121 of the first shell wall 120, the second buffer 212a can also form a limiting effect with the first shell wall 120, thereby limiting the movement of the extension section 210 toward the inner side of the mounting cavity 110, and thus limiting the movement of the shell 200 toward the inner side of the mounting cavity 110.

[0077] When the first buffer 124 and the second buffer 212a in the embodiments of this disclosure are rubber parts, the first buffer 124 can be a rubber block or a rubber ring. Similarly, the second buffer 212a can be a rubber block or a rubber ring, and there is no particular limitation in this regard.

[0078] In some embodiments of this disclosure, a limiting member is provided on the extension 210. When a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, the limiting member can engage with the first shell wall 120 to limit the relative position of the extension 210 and the first shell wall 120, preventing the extension 210 from moving along the depth direction of the first opening 122, thereby improving the stability of the first opening 122 in clamping and fixing the extension 210.

[0079] In some embodiments of this disclosure, a limiting member is disposed on the outer peripheral wall 212 of the extension 210, and the limiting member includes a limiting surface. When a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, the limiting member can abut against the first shell wall 120 through the limiting surface. The limiting member and the first shell wall 120 cooperate to restrict the movement of the extension 210 along the depth direction of the first opening 122, thereby restricting the movement of the fresh air module 20 along the depth direction of the first opening 122, thereby improving the stability of the first opening 122 in clamping and fixing the housing 200.

[0080] For example, see Figure 12 As shown, a first limiting member 213 is provided on the outer peripheral wall 212 of the extension section 210. When a portion of the extension section 210 protrudes from the outer wall surface 121 through the first opening 122, the first limiting member 213 is located on the side of the first shell wall 120 away from the shell 200. The first limiting member 213 has a first limiting surface 213a, which abuts against the outer wall surface 121. This restricts the entire fresh air module 20 from moving towards the inside of the mounting cavity 110 along the depth direction of the first opening 122, thereby improving the stability of the first opening 122 in clamping and fixing the shell 200.

[0081] See also, for example, Figure 12 As shown, a second limiting member 214 is provided on the outer peripheral wall 212 of the extension section 210. When a portion of the extension section 210 protrudes from the outer wall surface 121 through the first opening 122, the second limiting member 214 is located inside the mounting cavity 110. That is, the second limiting member 214 is located on the side of the first shell wall 120 facing the shell 200. The second limiting member 214 has a second limiting surface 214a, which abuts against the first shell wall 120. This restricts the movement of the entire fresh air module 20 along the depth direction of the first opening 122 toward the outside of the first shell wall 120, thereby improving the stability of the first opening 122 in clamping and fixing the shell 200.

[0082] In some embodiments of this disclosure, a limiting member is provided on the outer peripheral wall 212 of the extension 210, and a limiting fitting member is provided on the inner peripheral wall 122a of the first opening 122. When a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, the limiting member and the limiting fitting member abut against each other, thereby limiting the extension 210 and the first shell wall 120 in the depth direction perpendicular to the first opening 122. This improves the stability of the first opening 122 in holding the extension 210, and further restricts the movement of the shell 200 relative to the first shell wall 120 in the depth direction perpendicular to the first opening 122, thereby improving the installation stability of the fresh air module 20 in the mounting cavity 110.

[0083] For example, see Figure 13 As shown, in some cases, the limiting fitting can be a groove 122d, and the limiting member can be a protrusion 215. When a portion of the extension 210 protrudes from the outer wall surface 121 through the first opening 122, the limiting member can be embedded in the limiting fitting. This not only limits the extension 210 and the first shell wall 120 in the depth direction of the first opening 122, but also limits the extension 210 and the first shell wall 120 in the depth direction perpendicular to the first opening 122, thereby improving the stability of the first opening 122 in holding the extension 210.

[0084] In some embodiments of this disclosure, a second opening is provided on the outer casing 100 of the indoor unit 10 of the air conditioner, and the second opening communicates with the mounting cavity 110. See also Figure 5 and Figure 6 As shown, the housing 200 of the fresh air module 20 is provided with an air inlet 230, and the air inlet 230 is connected to the second opening. When the air conditioner indoor unit 10 of this embodiment is used indoors, the delivery pipe connected to the housing 100 is connected to the second opening, so that when the fresh air module 20 is working, it can draw in fresh outdoor air through the air inlet 230, the second opening and the delivery pipe.

[0085] In some embodiments of this disclosure, the indoor unit 10 of the air conditioner includes an indoor unit fan and an evaporator, both of which are installed in the mounting cavity 110. The fresh air module 20 is located on one side of the indoor unit fan or on one side of the evaporator along the width direction Y of the indoor unit 10.

[0086] Secondly, this disclosure provides an air conditioner including the aforementioned indoor unit 10, thus possessing the corresponding technical effects and advantages described above.

[0087] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0088] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0089] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0090] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0091] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0092] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0093] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0094] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0095] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0096] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
