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] However, current air conditioner indoor units are not very efficient at introducing fresh outdoor air into the room through the fresh air module, and the fresh air module will take up internal space of the air conditioner indoor unit, affecting the internal structural layout of the air conditioner indoor unit. Utility Model Content

[0004] To overcome the problems existing in related technologies, this disclosure provides an indoor air conditioning unit and an air conditioner. By setting the air outlet to protrude from the outer wall surface, the fresh air module is located outside the installation cavity. While keeping the size of the installation cavity unchanged, the space occupied by the fresh air module in the installation cavity can be reduced, which facilitates the installation and layout of various other components in the installation cavity, optimizes the internal structure of the indoor air conditioning unit, and allows the use of a larger volume fresh air module. This improves the efficiency of the indoor air conditioning unit in introducing fresh outdoor air into the room through the fresh air module, and further optimizes the indoor air quality.

[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; 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 air outlet that communicates with the first opening, and at least a portion of the air outlet protrudes from the outer wall surface of the first housing.

[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: By setting the air outlet to protrude from the outer wall surface, a portion of the fresh air module is located outside the mounting cavity. While maintaining the same size of the mounting cavity, this reduces the space occupied by the fresh air module, facilitating the installation and layout of other components within the mounting cavity and optimizing the internal structure of the indoor air conditioning unit. Furthermore, since a portion of the fresh air module is located outside the mounting cavity, a larger fresh air module can be selected while maintaining the same size of the mounting cavity, thereby improving the efficiency of the fresh air module in drawing in fresh outdoor air and expelling it into the room, further optimizing indoor air quality.

[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] Currently, when installing a fresh air module into an indoor air conditioning unit, a through hole is usually set at the top of the indoor air conditioning unit. The air outlet of the fresh air module is connected to the through hole, and the air outlet and the through hole are flush in the height direction, so that the fresh air module is located inside the indoor air conditioning unit.

[0035] Due to the limited internal space of the air conditioner indoor unit, only relatively small fresh air modules can be selected, resulting in low efficiency in introducing fresh outdoor air into the indoor unit through the fresh air module; moreover, the fresh air module occupies the internal space of the air conditioner indoor unit, which in turn affects the internal structural layout of the air conditioner indoor unit.

[0036] This disclosure provides an indoor air conditioning unit and an air conditioner. By setting the air outlet to protrude from the outer wall surface, the fresh air module is located outside the mounting cavity. While keeping the size of the mounting cavity unchanged, the space occupied by the fresh air module in the mounting cavity can be reduced, which facilitates the installation and layout of various other components in the mounting cavity, optimizes the internal structure of the indoor air conditioning unit, and allows the use of a larger volume fresh air module. This improves the efficiency of the indoor air conditioning unit in introducing fresh outdoor air into the room through the fresh air module, and further optimizes the indoor air quality.

[0037] Firstly, see [the following] Figures 1-4 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 casing, and the interior of the casing 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 first shell wall 120 with 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 shell 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 6 As shown, a first opening 122 is provided on the outer wall surface 121 of the first shell 120, and the first opening 122 communicates with the mounting cavity 110 inside the shell. The fresh air module 20 has an air outlet 221, and the air outlet 221 communicates with the first opening 122; when the fresh air module 20 is in working condition, the air outlet 221 can discharge the outdoor fresh air drawn by the fresh air module 20 into the room through 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. 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 delivery pipe can deliver fresh air from the outside to the fresh air module 20.

[0042] In this embodiment of the air conditioner indoor unit 10, at least a portion of the air outlet 221 protrudes from the outer wall surface 121 of the first housing 120; for example, when the plane containing the air outlet 221 intersects the plane containing the first opening 122, see [reference needed]. Figure 7 As shown, the air outlet 221 can partially protrude from the outer wall surface 121, see [reference]. Figure 8 As shown, the air outlet 221 can also protrude entirely from the outer wall surface 121; for example, when the plane containing the air outlet 221 is parallel to the plane containing the first opening 122, see [reference needed]. Figure 2 and Figure 3 As shown, the air outlet 221 protrudes completely from the outer wall surface 121. Since the air outlet 221 at least partially protrudes from the outer wall surface 121, the fresh air module 20 can be made visible on the indoor unit 10 of the air conditioner in this embodiment of the present disclosure.

[0043] It is worth mentioning that the fresh air module 20 has a certain volume, which means that when the fresh air module 20 is installed in the indoor unit 10 of the air conditioner, it will occupy the space of the mounting cavity 110, affecting the installation and layout of other components in the mounting cavity 110. This embodiment of the present disclosure, by setting the air outlet 221 to protrude from the outer wall surface 121, places part of the fresh air module 20 outside the mounting cavity 110. While maintaining the same size of the mounting cavity 110, this reduces the space occupied by the fresh air module 20, facilitating the installation and layout of other components in the mounting cavity 110 and optimizing the internal structure of the indoor unit 10 of the air conditioner.

[0044] Since part of the fresh air module 20 is located outside the installation cavity 110, a larger fresh air module 20 can be selected while keeping the size of the installation cavity 110 unchanged. This improves the efficiency of the fresh air module 20 in drawing fresh outdoor air and expelling fresh air into the room, thereby further optimizing the indoor air quality.

[0045] In some embodiments of this disclosure, see Figure 4 and Figure 5 As shown, the fresh air module 20 includes a housing 200, the interior of which has an inner cavity 210, in which a fan 211 is installed. The air outlet 221 of the fresh air module 20 is connected to the inner cavity 210 of the housing 200. When the fresh air module 20 is in operation, the fan 211 rotates, causing the fresh air module 20 to draw fresh outdoor air into the inner cavity 210 through the delivery pipe. With the continuous rotation of the fan 211, the fresh air module 20 then discharges the fresh air in the inner cavity 210 into the room through the air outlet 221.

[0046] Further, see Figure 2 and Figure 3 As shown, a portion of the housing 200 extends toward the direction of the first opening 122, such that an extension segment 220 is formed on the housing 200, and the extension segment 220 extends toward the direction of the first opening 122. At least a portion of the end of the extension segment 220 protrudes beyond the outer wall surface 121 of the first housing wall 120, wherein the air outlet 221 of the fresh air module 20 is located at the end of the extension segment 220. Because at least a portion of the end of the extension segment 220 protrudes beyond the outer wall surface 121, at least a portion of the air outlet 221 also protrudes beyond the outer wall surface 121.

[0047] It is understandable that when a portion of the end of the extension 220 protrudes beyond the outer wall surface 121, see [reference needed]. Figure 7 As shown, part of the air outlet 221 protrudes from the outer wall surface 121; when the entire end of the extension section 220 protrudes from the outer wall surface 121, see... Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the entire air outlet 221 protrudes from the outer wall surface 121.

[0048] In some embodiments of this disclosure, see Figures 9-13 As shown, a first vent 222 is provided on the outer peripheral wall 223 of the extension section 220, and the first vent 222 communicates with the inner cavity 210. The first vent 222 is located on the extension section 220 protruding from the outer wall surface 121. When the fresh air module 20 discharges fresh air into the room, it can be discharged through the air outlet 221 of the extension section 220 or through the first vent 222. This allows the first vent 222 to assist the air outlet 221 in discharging fresh air, thereby improving the efficiency of the fresh air module 20 in discharging fresh air into the room and further optimizing the indoor air quality.

[0049] Since the air outlet 221 is located at the end of the extension section 220, and the first vent 222 is located on the outer peripheral wall 223 of the extension section 220, the air outlet direction of the air outlet 221 in this embodiment intersects with the air outlet direction of the first vent 222. Furthermore, by designing the shape of the extension section 220 and the extension direction of the first vent 222, the air outlet direction of the air outlet 221 can be made to be the same as the air outlet direction of the first vent 222. Regardless of whether the air outlet direction of the air outlet 221 is the same as or intersects with the air outlet direction of the first vent 222, the first vent 222 can assist the air outlet 221 in discharging fresh air into the room.

[0050] It is worth mentioning that when the fresh air module 20 exhausts fresh air into the room, with the cooperation of the air outlet 221 and the first vent 222, the fresh air passing through the air outlet 221 and the first vent 222 is discharged into the room in multiple streams, which can achieve the diversion of the fresh air exhausted into the room, thereby reducing the impact force of the fresh air exhausted into the room by the fresh air module 20, and achieving the effect of gentle breeze.

[0051] In some embodiments of this disclosure, see Figure 1 and Figure 2 As shown, the first housing wall 120 is the top wall of the air conditioner indoor unit 10. Of course, in some cases, the first housing wall 120 can also be the bottom wall, left side wall 104 or right side wall 105 of the air conditioner indoor unit 10.

[0052] The indoor unit 10 of the air conditioner is generally fixedly installed on the wall of the room. Since the first shell wall 120 of this embodiment is the top wall of the indoor unit 10, when the fresh air module 20 is in working state, the air outlet 221 is directed towards the top of the indoor unit 10. When the installation height of the indoor unit 10 is adjusted so that the indoor unit 10 is close to the top surface of the wall, the fresh air discharged from the air outlet 221 can impact the top surface, thereby achieving the effect of cleaning the wall.

[0053] In some embodiments of this disclosure, at least a portion of the end of the extension 220 passes through the first opening 122 and protrudes from the outer wall surface 121. See also Figure 6 As shown, the first opening 122 has an inner peripheral wall 122a. In this embodiment of the disclosure, see [link to relevant documentation]. Figures 2-3 and Figures 7-13 As shown, the outer peripheral wall 223 of the extension segment 220 located in the first opening 122 fits against the inner peripheral wall 122a of the first opening 122, so that the first opening 122 can play an auxiliary positioning role for the extension segment 220, improve the installation accuracy of the extension segment 220, and thus improve the installation accuracy of the fresh air module 20.

[0054] The outer peripheral wall 223 of the extension section 220 is fitted with the inner peripheral wall 122a of the first opening 122. Specifically, it can be partially fitted or fully fitted. When the outer peripheral wall 223 of the extension section 220 is fully fitted with the inner peripheral wall 122a of the first opening 122, the first opening 122 can also clamp the extension section 220. This allows the first opening 122 to assist in positioning the extension section 220 while also fixing it. This improves the positional stability of the extension section 220 and ensures that at least part of the air outlet 221 protrudes from the outer wall surface 121, thereby improving the positional stability of the fresh air module 20.

[0055] Since the first opening 122 is provided so that at least part of the air outlet 221 protrudes from the outer wall surface 121, in some cases, the inner wall surface of the first opening 122 and the outer peripheral wall 223 of the extension 220 can also be spaced apart.

[0056] In some embodiments of this disclosure, a limiting member is provided on the extension 220. When at least a portion of the end of the extension 220 protrudes from the outer wall surface 121, the limiting member can engage with the first shell wall 120 to limit the relative position of the extension 220 and the first shell wall 120, thereby maintaining the stability of the air outlet 221 protruding from the outer wall surface 121.

[0057] In some embodiments of this disclosure, a limiting member is disposed on the outer peripheral wall 223 of the extension 220, and the limiting member includes a limiting surface. When at least a portion of the end of the extension 220 protrudes from the outer wall surface 121, 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 220 along the depth direction X of the first opening 122, thereby restricting the movement of the housing 200 of the fresh air module 20 along the depth direction X of the first opening 122, and keeping at least a portion of the air outlet 221 protruding from the outer wall surface 121.

[0058] For example, see Figure 10 As shown, a first limiting member 224 is provided on the outer peripheral wall 223 of the extension section 220. When at least a portion of the end of the extension section 220 protrudes from the outer wall surface 121, the first limiting member 224 is located on the side of the first shell wall 120 away from the shell 200. The first limiting member 224 has a first limiting surface 224a, and the first limiting member 224 abuts against the outer wall surface 121 through the first limiting surface 224a, thereby restricting the entire fresh air module 20 from moving towards the inside of the mounting cavity 110 along the depth direction X of the first opening 122, so as to maintain the stability of the air outlet 221 protruding from the outer wall surface 121.

[0059] See also, for example, Figure 10 As shown, a second limiting member 225 is provided on the outer peripheral wall 223 of the extension section 220. When at least a portion of the end of the extension section 220 protrudes from the outer wall surface 121, the second limiting member 225 is located within the mounting cavity 110. That is, the second limiting member 225 is located on the side of the first shell wall 120 facing the shell 200. The second limiting member 225 has a second limiting surface 225a. The second limiting member 225 abuts against the first shell wall 120 through the second limiting surface 225a, thereby restricting the movement of the entire fresh air module 20 along the depth direction X of the first opening 122 toward the outside of the first shell wall 120, so as to maintain the stability of the air outlet 221 protruding from the outer wall surface 121.

[0060] In some embodiments of this disclosure, a limiting member is provided on the outer peripheral wall 223 of the extension 220, and a limiting fitting member is provided on the inner peripheral wall 122a of the first opening 122. When at least a portion of the end of the extension 220 protrudes from the outer wall surface 121, the limiting member and the limiting fitting member abut against each other, thereby limiting the extension 220 and the first shell wall 120 in the depth direction X perpendicular to the first opening 122. This maintains the stability of the air outlet 221 protruding from the outer wall surface 121 and restricts the movement of the housing 200 relative to the first shell wall 120 in the depth direction X perpendicular to the first opening 122, thereby improving the installation stability of the fresh air module 20 in the mounting cavity 110.

[0061] For example, see Figure 11 As shown, in some cases, the limiting fitting can be a groove 122b, and the limiting member can be a protrusion 226. With at least a portion of the end of the extension 220 protruding from the outer wall surface 121, the limiting member can be embedded in the limiting fitting, thereby limiting the extension 220 and the first shell wall 120 not only in the depth direction X of the first opening 122, but also in the depth direction X perpendicular to the first opening 122, to maintain the stability of the air outlet 221 protruding from the outer wall surface 121.

[0062] In some embodiments of this disclosure, see Figures 6-13 As shown, a cover 300 is provided on the outer wall surface 121 of the first shell wall 120, and the position of the cover 300 corresponds to the position of the first opening 122. Since the air outlet 221 protrudes from the outer wall surface 121 through the first opening 122, the cover 300 can cover the outside of the air outlet 221, and the cover 300 can hide and protect the air outlet 221 that protrudes from the outer wall surface 121.

[0063] Furthermore, a second vent 310 is provided on the housing 300, and the second vent 310 is connected to the air outlet 221. When the fresh air module 20 is in operation, the fresh outdoor air drawn by the fresh air module 20 can be discharged into the room through the air outlet 221, the first vent 222, and the second vent 310. More specifically, the fresh air in the inner cavity 210 of the housing 200 can be discharged into the room through the air outlet 221 and the second vent 310, or through the first vent 222 and the second vent 310.

[0064] The cover 300 of this embodiment covers the air outlet 221 while maintaining the connection between the air outlet 221 and the room through the second vent 310, ensuring that the fresh air module 20 can provide fresh outdoor air to the room.

[0065] In some embodiments of this disclosure, see Figures 6-13 As shown, a receiving cavity 320 is formed between the cover 300 and the outer wall surface 121. Specifically, the side of the cover 300 facing the outer wall surface 121 is recessed inward, so that when the cover 300 is installed on the outer wall surface 121, a receiving cavity 320 can be formed between the cover 300 and the outer wall surface 121. In this embodiment, since at least a portion of the end of the extension 220 protrudes from the outer wall surface 121 through the first opening 122, and the position of the cover 300 corresponds to the position of the first opening 122, the extension 220 protruding from the outer wall surface 121 can be located in the receiving cavity 320.

[0066] When the fresh air module 20 is in operation, the fresh air in the inner cavity 210 is first discharged into the receiving cavity 320 from the air outlet 221 and the first vent 222, and then the fresh air is discharged into the room through the second vent 310. Since the fresh air transitions in the receiving cavity 320 before entering the room, when the fresh air enters the receiving cavity 320, the fresh air diffuses in the receiving cavity 320, so that the cover 300 can buffer the fresh air discharged from the air outlet 221 and the first vent 222 through the receiving cavity 320, reduce the flow rate of the fresh air, and achieve a gentle breeze effect when the fresh air is discharged into the room through the second vent 310.

[0067] In some embodiments of this disclosure, see Figures 6-11 and Figure 13 As shown, the position of the second vent 310 is opposite to the position of the first opening 122. More specifically, the positions of the second vent 310 and the first opening 122 are opposite in the depth direction X of the first opening 122.

[0068] In this embodiment of the disclosure, see Figures 9-11 As shown, the end of the extension 220 is recessed into the edge of the second vent 310, so that the air outlet 221 is entirely located within the receiving cavity 320. This allows fresh air discharged from the air outlet 221 and the first vent 222 to first enter the receiving cavity 320, and then be discharged into the room through the second vent 310. In some cases, see... Figure 13 As shown, the end of the extension section 220 can also be flush with the edge of the second vent 310, so that fresh air in the inner cavity 210 of the housing 200 can only be discharged into the room through the air outlet 221 and the second vent 310 in sequence.

[0069] It is particularly important to note that, see [link / reference] Figures 9-11 As shown, when the end of the extension section 220 is recessed into the edge of the second vent 310, fresh air will transition within the receiving cavity 320 before entering the room through the second vent 310. When fresh air enters the receiving cavity 320, it diffuses within it, allowing the cover 300 to buffer the fresh air discharged from the air outlet 221 and the first vent 222 through the receiving cavity 320, reducing the airflow velocity and achieving a gentle breeze effect when fresh air is discharged into the room through the second vent 310. (See also...) Figure 13As shown, when the end of the extension section 220 is flush with the edge of the second vent 310, during the process of fresh air being discharged into the room through the air outlet 221 and the second vent 310, some fresh air will enter the receiving cavity 320 through the first vent 222. Then, the fresh air in the receiving cavity 320 will return to the extension section 220 through the first vent 222 and be discharged into the room through the air outlet 221 and the second vent 310. During the process of fresh air flowing through the first vent 222, the flow of fresh air can be turbulent, thereby slowing down the flow rate of fresh air discharged into the room from the air outlet 221 and the second vent 310, thus achieving the effect of gentle breeze.

[0070] In some embodiments of this disclosure, the first housing wall 120 can be the top wall, bottom wall, left side wall 104, or right side wall 105 of the indoor unit 10, and the second vent 310 can be located on the side of the housing 300 facing the front side wall 102 and / or rear side wall 103 of the indoor unit 10. For example, see... Figure 1 and Figure 12 As shown, in this embodiment of the present disclosure, the first shell wall 120 is the top wall of the indoor unit 10 of the air conditioner, the cover 300 is disposed on the top wall, and the second vent 310 can be disposed on the side of the cover 300 facing the front side wall 102 or on the side of the cover 300 facing the rear side wall 103, so that the second vent 310 can discharge fresh air into the room in the horizontal direction.

[0071] In some embodiments of this disclosure, see Figure 6 As shown, a second opening 123 is provided on the first shell wall 120, and the position of the second opening 123 corresponds to the position of the cover 300, so that the second opening 123 communicates with the receiving cavity 320, thereby making the mounting cavity 110 of the outer shell communicate with the receiving cavity 320. In this embodiment of the disclosure, see... Figures 7-13 As shown, at least a portion of the housing 200 of the fresh air module 20 passes through the second opening 123, such that a portion of the housing protrudes from the outer wall surface 121 of the first housing wall 120, and the portion of the housing protruding from the outer wall surface 121 is located within the receiving cavity 320.

[0072] It is understood that the fresh air module 20 includes a housing 200, on which an extension section 220 is provided. In this embodiment, the entire fresh air module 20 is moved upward within the mounting cavity 110 so that at least a portion of the end of the extension section 220 protrudes from the outer wall surface 121. During this process, the housing 200 of the fresh air module 20 moves upward as a whole. Since the first housing wall 120 will block the movement of the housing 200, this embodiment provides a second opening 123 on the first housing wall 120 so that the housing 200 can pass through the second opening 123 and protrude from the outer wall surface 121. This allows the housing 200 to move upward as a whole, thereby enabling at least a portion of the end of the extension section 220 to protrude from the outer wall surface 121, and enabling at least a portion of the air outlet 221 to protrude from the outer wall surface 121.

[0073] It is worth mentioning that a portion of the housing 200 protrudes from the outer wall surface 121 through the second opening 123. This reduces the space occupied by the fresh air module 20 in the mounting cavity 110 while maintaining the same size of the cavity. This facilitates the installation and layout of other components within the mounting cavity 110, and optimizes the internal structure of the indoor air conditioning unit 10. Furthermore, since a portion of the housing 200 is located outside the mounting cavity 110, a larger fresh air module 20 can be selected while maintaining the same size of the cavity. This improves the efficiency of the fresh air module 20 in drawing in fresh outdoor air and expelling it into the room, further optimizing indoor air quality.

[0074] In some embodiments of this disclosure, see Figure 1 and Figure 2 As shown, the outer casing of the air conditioner indoor unit 10 has a second shell wall 130, and the position of the second shell wall 130 is opposite to the position of the first shell wall 120. For example, in this embodiment of the present disclosure, the first shell wall 120 is the top wall of the air conditioner indoor unit 10, and the second shell wall 130 is the bottom wall of the air conditioner indoor unit 10.

[0075] In this embodiment, the position of the fresh air module 20 within the mounting cavity 110 is shifted upwards, meaning the fresh air module 20 moves towards the first shell wall 120 within the mounting cavity 110. This allows a receiving area 131 to be formed between the fresh air module 20 and the inner wall surface of the second shell wall 130. (See [link]). Figure 2 As shown, this reduces the space occupied by the fresh air module 20 in the installation cavity 110.

[0076] It is worth mentioning that, since a receiving area 131 is formed between the fresh air module 20 and the second shell wall 130, the corresponding components in the indoor unit 10 can extend into or be installed within the receiving area 131. This facilitates the installation and layout of the corresponding components in the mounting cavity 110, thereby optimizing the internal structure of the indoor unit 10. Furthermore, since the receiving area 131 is the space formed within the mounting cavity 110 after the fresh air module 20 is moved upwards, a larger fresh air module 20 can be installed within the mounting cavity 110 without changing its size. This improves the efficiency of the fresh air module 20 in drawing in fresh outdoor air and expelling it into the room, further optimizing indoor air quality.

[0077] In some embodiments of this disclosure, a third opening is provided on the outer casing of the indoor air conditioner unit 10, and the third opening communicates with the mounting cavity 110. An air inlet 201 is provided on the casing 200 of the fresh air module 20, and the air inlet 201 communicates with the third opening. When the indoor air conditioner unit 10 of this disclosure is used indoors, a delivery pipe connected to the outer casing communicates with the third opening, so that when the fresh air module 20 is working, it can draw in fresh outdoor air through the air inlet 201, the third opening, and the delivery pipe.

[0078] 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.

[0079] Secondly, this disclosure provides an air conditioner including the aforementioned indoor unit 10, thus possessing the corresponding technical effects and advantages described above.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.”

[0087] 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.”

[0088] 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.

[0089] 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.
