[0057] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0058] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0059] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0060] Hereinafter, with reference to the accompanying drawings, a window air conditioner 1 according to an embodiment of the present invention will be described. The type of window air conditioner 100 is not limited. For example, the window air conditioner 100 may be a cooling-only / heating-only window air conditioner or a heat pump window air conditioner.

[0061] like Figures 1-5 and Figures 13-18 As shown, the window air conditioner 1 includes an indoor unit 10 suitable for installation on the indoor side and an outdoor unit 20 suitable for installation on the outdoor side. The indoor unit 10 includes an indoor unit housing 12 and an air duct assembly 14. The indoor unit housing 12 has an air outlet area 120 and an air inlet area 122. The air inlet area 122 and the air outlet area 120 are located on different side walls of the indoor unit housing 12. The air outlet area 120 includes a front air outlet area 1200 opened on the side wall of the indoor unit housing 12 away from the outdoor unit 20. The air duct assembly 14 is disposed inside the indoor unit housing 12 and has a fan wheel cavity 140 and multiple air duct cavities 141. An indoor fan wheel 142 is provided in the fan wheel cavity 140. The multiple air duct cavities 141 are respectively connected to the periphery of the fan wheel cavity 140 and are respectively connected to different parts of the front air outlet area 1200. At least a portion of two adjacent air duct cavities 141 are separated.

[0062] As can be seen, airflow can enter the indoor unit 10 through the air inlet area 122, and after being processed by the window air conditioner 1, it is blown into the room through the air outlet area 120. The air outlet area 120 and the air inlet area 122 of the window air conditioner 1 are respectively located on different side walls of the indoor unit casing 12, so that there is a large gap between the air outlet area 120 and the air inlet area 122, which effectively reduces the possibility of cross-flow of air inlet and return, improves the problem of short-circuiting of return air in the window air conditioner 1, and facilitates the airflow delivered through the air outlet area 120 to fully diffuse and exchange heat in the indoor space, which is conducive to improving the temperature regulation effect of the window air conditioner 1. Moreover, the air inlet area 122 does not easily affect the setting position and size of the air outlet area 120, so that the setting position and setting form of the air outlet area 120 are more flexible and easy to adapt to different usage requirements.

[0063] In addition, the front air outlet area 1200 is located on the side wall of the indoor unit housing 12 away from the outdoor unit component 20, that is, the front air outlet area 1200 can be set facing the room so that the airflow processed by the window air conditioner 1 can be more fully diffused into the room through the front air outlet area 1200.

[0064] It is understood that the air intake area 122 is not located on the side wall of the indoor unit housing 12 away from the outdoor unit component 20 (or the front side wall of the indoor unit housing 12). Therefore, the air outlet area 120 may only include the front air outlet area 1200. In this case, the air intake area 122 may be located on at least one of the left side wall, right side wall, upper side wall, lower side wall, and rear side wall of the indoor unit housing 12. The air intake area 122 is usually provided with an air intake grille to restrict foreign objects from entering the interior of the indoor unit housing 12. The above-mentioned setting of the air intake area 122 ensures that when the user uses the window air conditioner 1, the user will not see the air intake grille on the side wall of the indoor unit housing 12 away from the outdoor unit component 20 (or the front side wall of the window air conditioner 1 facing the user), thus making the window air conditioner... The appearance of device 1 is more aesthetically pleasing and technologically advanced; or, the air outlet area 120 includes not only the front air outlet area 1200, but also areas on other side walls of the inner unit housing 12 for air outlet, such as at least one of the upper air outlet area on the upper side wall of the inner unit housing 12, the lower air outlet area on the lower side wall of the inner unit housing 12, the left air outlet area on the left side wall of the inner unit housing 12, and the right air outlet area on the right side wall of the inner unit housing 12. The air inlet area 122 may be located only on the rear side wall of the inner unit housing 12, or the air inlet area 122 may be located on the upper side wall, lower side wall, left side wall, right side wall of the inner unit housing 12, and the other side walls besides at least one of the above, as well as the rear side wall.

[0065] The air duct assembly 14 includes a fan wheel cavity 140 and multiple air duct cavities 141. The multiple air duct cavities 141 are respectively connected to the periphery of the fan wheel cavity 140. Thus, an indoor fan wheel 142 can drive airflow to multiple air duct cavities 141 arranged around the fan wheel cavity 140, which can reduce the number of indoor fan wheels 142 used, making the structure of the window air conditioner 1 simpler and easier for mass production. The multiple air duct cavities 141 are respectively connected to different parts of the front air outlet area 1200. For example, the front air outlet area 1200 includes multiple sub-air outlet areas. The multiple air duct cavities 141 are connected to the multiple sub-air outlet areas one by one. At the same time, the multiple sub-air outlet areas can also be arranged on the side wall of the indoor unit casing 12 along the periphery of the fan wheel cavity 140 to increase the coverage of the front air outlet area 1200 and improve the cooling and heating effect of the window air conditioner 1. The two adjacent air duct cavities 141 are at least partially separated so that the airflow path is more clearly defined after being driven by the indoor fan wheel 142, which helps to reduce mutual interference of airflow, reduce the possibility of eddies or turbulence, and improve the air outlet performance of the window air conditioner 1.

[0066] In contrast to some technologies where the air outlet and air inlet areas of a window air conditioner are located on the same side wall of the indoor unit casing, making it easy for airflow to generate short circulation, and the arrangement of the air outlet area is limited by the air inlet area, requiring multiple fans for multiple duct systems to achieve the air outlet of the window air conditioner; however, the window air conditioner 1 according to the present invention effectively reduces the possibility of cross-flow of air inlet and outlet by setting the air outlet area 120 and the air inlet area 122 on different side walls of the indoor unit casing 12, and the air inlet area 122 does not easily affect the setting position of the air outlet area 120. The duct assembly 14 has multiple duct chambers 141 to connect to different parts of the front air outlet area 1200, thereby increasing the air outlet range of the window air conditioner 1 and improving the cooling and heating effect of the window air conditioner 1. Moreover, the air supply of multiple duct chambers 141 can be achieved through one indoor fan wheel 142, simplifying the structure of the window air conditioner 1 and improving the mass production of the window air conditioner 1.

[0067] In some embodiments, the front air outlet area 1200 is formed as an annular area extending about a horizontal axis, the horizontal axis extending along the direction from the indoor unit component 10 toward the outdoor unit component 20; or, as... Figure 5 and Figure 18 As shown, the front air outlet area 1200 includes a plurality of front air outlets 1202 spaced apart around a horizontal axis, and a plurality of air duct cavities 141 are connected one-to-one to the plurality of front air outlets 1202. The horizontal axis extends along the direction from the indoor unit component 10 toward the outdoor unit component 20.

[0068] As can be seen, the front air outlet area 1200 can be a ring-shaped area. The ring-shaped front air outlet area 1200 has a wider air outlet range, which allows the airflow to be more evenly diffused into the room, reducing dead air angles and improving the cooling and heating effects of the window air conditioner 1; or, the front air outlet area 1200 includes multiple rings around the horizontal axis (such as... Figure 4 The front air outlets 1202 arranged at intervals (L1) in the window air conditioner 1 can increase the coverage of the front air outlet area 1200, so that the airflow can be evenly diffused into the room through multiple front air outlets 1202. At the same time, the arrangement of multiple front air outlets 1202 is more flexible, which can meet different usage needs. For example, multiple front air outlets 1202 can be arranged at intervals along the horizontal direction of the window air conditioner 1, or multiple front air outlets 1202 can be arranged at intervals along the vertical direction of the window air conditioner 1.

[0069] Obviously, in the above scheme, whether the front air outlet area 1200 is formed into a ring area or includes multiple front air outlets 1202, the form of the front air outlet area 1200 can be well matched with the arrangement of multiple air duct cavities 141, which is conducive to appropriately reducing flow resistance and improving air outlet smoothness.

[0070] It is understood that in this embodiment of the application, the window air conditioner 1 is installed at the window, the inward and outward directions of the window (i.e., the direction through the window) are the front-to-back directions, the height direction of the window is the up-down direction, and the width direction of the window is the left-to-right direction. In the above scheme, the horizontal axis can extend along the front-to-back direction.

[0071] In some embodiments, the front air outlet area 1200 is formed as a polygonal annular area. This polygonal annular design helps to disperse airflow more effectively during air outlet, preventing localized airflow from becoming too concentrated, thus achieving a more uniform airflow distribution. This reduces discomfort caused by uneven airflow and improves the air outlet performance of the window air conditioner 1. For example, the front air outlet area 1200 can be a circular annular area, a rectangular annular area, a square annular area, an irregular polygonal annular area, etc.; or, as... Figure 5 and Figure 18 As shown, the front air outlet area 1200 includes multiple front air outlets 1202, each of which extends in a straight line as an elongated opening, so that the shape of the front air outlet 1202 is more regular, which is convenient for processing and manufacturing and is conducive to the large-scale production of window air conditioner 1.

[0072] like Figures 4-6 As shown, in some embodiments, the sidewalls of the indoor unit housing 12 where the front air outlet area 1200 is located are vertically arranged, so that the shape of the indoor unit housing 12 is simpler, easier to process and manufacture, and easier to form the front air outlet area 1200.

[0073] The indoor unit component 10 also includes multiple air guide structures 16, each of which is located in the front air outlet area 1200 and corresponds one-to-one with multiple air duct cavities 141. Each air guide structure 16 is located at the outlet 1430 of the corresponding air duct cavity 141, and each air guide structure 16 is rotatably mounted on the air duct assembly 14 or the indoor unit housing 12 to change the airflow direction of different parts of the front air outlet area 1200. Thus, each air guide structure 16 is rotatably located at the outlet 1430 of each air duct cavity 141, so that the air guide structure 16 can change the airflow direction of different parts of the front air outlet area 1200 and / or switch different parts of the front air outlet area 1200.

[0074] Therefore, the air guide structure 16 can change the airflow direction. By controlling the air guide structure 16, directional or diffused airflow can be achieved, facilitating diverse airflow effects and meeting different user needs. And / or, the air guide structure 16 can also open and close different parts of the front air outlet area 1200, thus providing a protective function. For example, when the window air conditioner 1 is not in use, the air guide structure 16 can close the front air outlet area 1200 to reduce the possibility of dust and debris falling into the window air conditioner 1, thereby maintaining the cleanliness and normal operation of the window air conditioner 1. When the window air conditioner 1 is running, the air guide structure 16 can open the front air outlet area 1200 to allow airflow to flow into the room through the front air outlet area 1200. The air guide structure 16 can be located on the duct assembly 14 or the indoor unit housing 12, making its placement more flexible and adaptable to different installation environments.

[0075] As can be seen, since the side wall of the indoor unit housing 12, where the front air outlet area 1200 is located, is vertically arranged, the ventilation direction of different parts of the front air outlet area 1200 is relatively consistent. Therefore, the air guide structure 16 is provided to improve the air supply problem caused by the simple arrangement of the front air outlet area 1200. Moreover, the multiple air guide structures 16 corresponding to different parts of the front air outlet area 1200 have a certain degree of consistency in arrangement, which is beneficial to improving assembly efficiency. Optionally, the air guide structure 16 is constructed as an air guide plate, and the shape of the air guide plate is consistent with the corresponding part of the front air outlet area 1200. For example, the front air outlet area 1200 includes multiple front air outlets 1202, each front air outlet 1202 is formed as an elongated opening, and each front air outlet 1202 is provided with an elongated air guide plate.

[0076] like Figure 5 and Figure 18As shown, in some embodiments, the front air outlet area 1200 includes a plurality of front air outlets 1202, each of which includes a first front air outlet 1202a. There are two first front air outlets 1202a, and these two first front air outlets 1202a are vertically spaced apart. Each first front air outlet 1202a extends horizontally. The two vertically spaced first front air outlets 1202a facilitate an increase in the coverage area of ​​the airflow through the front air outlet area 1200, which is advantageous. To improve the cooling and heating effect of the window air conditioner 1; and / or, the plurality of front air outlets 1202 include two second front air outlets 1202b, which are arranged horizontally and spaced apart. Each second front air outlet 1202b extends vertically. By using two second air outlets arranged horizontally and spaced apart, it is easier to increase the coverage of the airflow through the front air outlet area 1200, which is beneficial to improving the cooling and heating effect of the window air conditioner 1.

[0077] In some embodiments, a plurality of front air outlets 1202 correspond one-to-one with a plurality of air duct cavities 141, and a plurality of air guiding structures 16 correspond one-to-one with a plurality of front air outlets 1202. Each air guiding structure 16 is respectively disposed on the corresponding front air outlet 1202, and each air guiding structure 16 is rotatably mounted on the air duct assembly 14 or the indoor unit housing 12, so that the air guiding structure 16 can change the airflow direction through the corresponding front air outlet 1202, so as to meet different usage requirements.

[0078] For example, such as Figure 4 and Figure 5 As shown, the multiple front air outlets 1202 include two first front air outlets 1202a arranged vertically at intervals. The upper air guide structure 16 tilts down to control the airflow towards the lower front part of the window air conditioner 1, and the lower air guide structure 16 tilts up to control the airflow towards the upper front part of the window air conditioner 1. This forms an enveloping air supply experience with airflow from both the upper and lower sides, providing users with a windless, enveloping comfort experience during cooling and heating. Alternatively, the upper air guide structure 16 tilts down to control the airflow towards the lower front part of the window air conditioner 1, and the lower air guide structure 16 also tilts down to control the airflow towards the lower front part of the window air conditioner 1, achieving a carpet-like lower air supply experience during cooling. Alternatively, the upper air guide structure 16 tilts up to control the airflow towards the upper front part of the window air conditioner 1, and the lower air guide structure 16 also tilts up to control the airflow towards the upper front part of the window air conditioner 1, achieving a shower-like upper air supply experience during cooling.

[0079] For example, such as Figure 16 and Figure 18As shown, the multiple front air outlets 1202 include two second front air outlets 1202b arranged horizontally at intervals. The air guide structure 16 on the left flips to the right to guide the airflow toward the front right side of the window air conditioner 1, and the air guide structure 16 on the right flips to the left to guide the airflow toward the front left side of the window air conditioner 1. This forms a left-right air outlet surrounding air supply experience, which can provide users with a windless surrounding comfort experience when cooling or heating; or, the two air guide structures 16 simultaneously flip left and right and operate continuously, so that the air outlet is evenly distributed to the entire front space of the window air conditioner 1, realizing an immersive overall air supply experience when cooling or heating.

[0080] It is understandable that, regardless of the arrangement of the front air outlet area 1200, the corresponding multiple air guiding structures 16 can be independently rotated. Of course, when the window air conditioner 1 is supplying air, at least one of the multiple air guiding structures 16 can close the corresponding part of the front air outlet area 1200, which facilitates further enrichment of the air supply modes. For example, for the two first front air outlets 1202a, one of the air guiding structures 16 can be conveniently positioned to correspond to the first front air outlet 1202a, and the window air conditioner 1 supplies air through the other first front air outlet 1202a.

[0081] like Figure 5 and Figure 18 As shown, in some embodiments, the indoor impeller 142 is a centrifugal impeller, and the front air outlet area 1200 is arranged around the central axis of the centrifugal impeller. The centrifugal impeller discharges air radially, and multiple air duct cavities 141 are respectively connected to the periphery of the impeller cavity 140. Thus, the multiple air duct cavities 141 are respectively connected to the air outlet side of the centrifugal impeller, so that the above arrangement of the front air outlet area 1200 is well matched with the air outlet mode of the centrifugal impeller, which is beneficial to improving the air supply performance of the window air conditioner 1.

[0082] It is understood that the front air outlet area 1200 may be arranged in a complete circle around the central axis of the centrifugal impeller, or less than a complete circle. For example, the front air outlet area 1200 is formed as a ring-shaped area around the central axis of the centrifugal impeller; or, the plurality of front air outlets 1202 include a plurality of front air outlets 1202 spaced apart along the circumference of the centrifugal impeller. Obviously, the central axis of the centrifugal impeller can be the horizontal axis described above. Further optionally, the plurality of front air outlets 1202 includes two first front air outlets 1202a spaced apart in the vertical direction, and the two first front air outlets 1202a are respectively located on the upper and lower sides of the central axis of the centrifugal impeller; and / or, the plurality of front air outlets 1202 includes two second front air outlets 1202b spaced apart in the horizontal direction, and the two second front air outlets 1202b are respectively located on the left and right sides of the central axis of the centrifugal impeller.

[0083] In some embodiments, such as Figure 4 , Figure 5 , Figure 16 and Figure 18 As shown, the indoor impeller 142 is a centrifugal impeller, and the air duct assembly 14 includes a front volute 143 and a rear volute 144. The front volute 143 is located on the side of the rear volute 144 away from the outdoor unit component 20. The front volute 143 and the rear volute 144 define the impeller cavity 140 and the air duct cavity 141. The side of the front volute 143 away from the rear volute 144 defines the mounting cavity 145. For example, the front volute 143 cooperates with the indoor unit housing 12 to define the mounting cavity 145, or the front volute 143 is processed with a certain amount of empty space to define the mounting cavity 145. The mounting cavity 145 is equipped with a drive motor 146 connected to the indoor impeller 142, so that external impurities are not easily allowed to enter the mounting cavity 145 and affect the normal operation of the drive motor 146, which facilitates the improvement of the stability of the drive motor 146. Moreover, the arrangement of the drive motor 146 does not occupy the internal space of the impeller cavity 140 and the air duct cavity 141.

[0084] In this configuration, each air duct cavity 141 is separated from the others and located around the drive motor 146. Thus, multiple air duct cavities 141 are respectively located around the drive motor 146. The front air outlet area 1200 is arranged around the central axis of the centrifugal impeller and is also located around the drive motor 146. The multiple air duct cavities 141 correspond to different portions of the front air outlet area 1200. It can be understood that, to better transmit torque from the drive motor 146 to the indoor impeller 142, the indoor impeller 142 and the drive motor 146 can be arranged opposite each other in the horizontal direction, and the multiple air duct cavities 141 can also be respectively located around the indoor impeller 142.

[0085] As can be seen, by setting the indoor fan 142 as a centrifugal fan with axial air intake and radial air outlet, and by distributing multiple air duct cavities 141 at intervals around the centrifugal fan, the air intake and exhaust methods of the air duct cavities 141 and the centrifugal fan are more compatible. This facilitates the setting of one indoor fan 142 supplying air to multiple air duct cavities 141, which helps to increase the coverage of the front air outlet area 1200 of the window air conditioner 1, improve the cooling and heating effect of the window air conditioner 1, and simplify the structure of the window air conditioner 1, which is conducive to the large-scale production and manufacturing of the window air conditioner 1.

[0086] like Figures 10-12 , Figure 21 and Figure 24As shown, in some embodiments, the air duct cavity 141 includes a diffuser section 1410 and an exhaust section 1412. Both the diffuser section 1410 and the impeller cavity 140 are located between the front volute 143 and the rear volute 144. The exhaust section 1412 is located on the front volute 143 and is situated on one side of the impeller cavity 140 in a first direction. Multiple exhaust sections 1412 are arranged around the periphery of the drive motor 146. The diffuser section 1410 is at least connected to one side of the impeller cavity 140 in a second direction and also connects to the exhaust section 1412. The first and second directions intersect, and both are perpendicular to the axial direction of the air duct cavity 141, which is the axial direction of the indoor impeller 142. The first and second directions intersect to allow for more flexible placement of the diffuser section 1410 and the exhaust section 1412, making them suitable for different usage scenarios.

[0087] As can be seen, the diffuser section 1410 can be connected to the air outlet side of the indoor impeller 142, and can be used to collect and guide the airflow, and convert part of the dynamic pressure energy of the airflow into static pressure energy. Then, it is blown to the front air outlet area 1200 through the exhaust section 1412. By setting the exhaust section 1412 and the diffuser section 1410, it is more suitable for the air inlet and outlet mode of the centrifugal impeller, so that the airflow path in the air duct cavity 141 is clearer, which makes it easier to reduce the loss of airflow in the air duct cavity 141. Moreover, the above-mentioned setting of the diffuser section 1410 and the exhaust section 1412 is not concentrated on the same structural component, which makes it easier to simplify the structure of the front volute 143 and the rear volute 144, and at the same time, it is easy to realize the separate setting of the exhaust section 1412 of multiple air duct cavities 141.

[0088] like Figure 7 , Figures 10-12 , Figure 21 , Figure 23 and Figure 24 As shown, in some embodiments, the air duct cavity 141 further includes a guide section 1414, and the diffuser section 1410 is connected to the exhaust section 1412 through the guide section 1414. In the circumferential direction of the impeller cavity 140, the guide section 1414 is disposed between two adjacent diffuser sections 1410. The inlet 1440 of the impeller cavity 140 is formed on the rear volute 144, and the rear volute 144 also has a guide portion 1442 disposed on the outer periphery of the inlet 1440. The guide portion 1442 helps to define the guide section 1414, and the guide portion 1442 extends along the impeller cavity. The radial outward extension of 140 towards the front volute 143 allows airflow to enter the impeller cavity 140 through the inlet 1440, then be transmitted to the guide section 1414 through the diffuser section 1410, and then to the exhaust section 1412 through the guide section 1414. The guide section 1414 can guide the airflow to pass more smoothly through the diffuser section 1410 to the exhaust section 1412, making the airflow path clearer, reducing turbulence or eddies in the air duct cavity 141, and improving the air outlet performance of the window air conditioner 1.

[0089] In some embodiments, the plurality of air duct cavities 141 are arranged in a rotationally symmetrical manner about the central axis of the indoor impeller 142. The plurality of air duct cavities 141 have the same structure and the arrangement can be adapted to the air outlet method of the centrifugal impeller and the shape of the front air outlet area 1200.

[0090] In some embodiments, one of the first direction and the second direction is a horizontal direction and the other is a vertical direction. There are two air duct cavities 141, each of which includes a diffuser section 1410 and an exhaust section 1412, so that the airflow can flow through the corresponding diffuser section 1410 and exhaust section 1412 to the front air outlet area 1200, reducing the possibility of mutual interference of airflow and facilitating the improvement of the air outlet performance of the window air conditioner 1.

[0091] Among them, the two air duct cavities 141 are about the central axis of the indoor impeller 142 (e.g. Figure 4 The L1 in the design is rotationally symmetrical, which makes the setting position of the air duct cavity 141 more flexible, and the arrangement position of the front air outlet area 1200 more flexible, so as to adapt to different usage needs.

[0092] For example, in Figure 10 and Figure 12 In the example, the first direction is vertical, and the second direction is horizontal. The diffuser section 1410 connects to one side of the ventilation wheel cavity 140 in the horizontal direction and extends vertically toward the corresponding exhaust section 1412. Taking the second direction as left-right as an example, the left diffuser section 1410 connects to the left side of the ventilation wheel cavity 140 and extends upward along the airflow direction to connect with the upper exhaust section 1412. The right diffuser section 1410 connects to the right side of the ventilation wheel cavity 140 and extends downward along the airflow direction to connect with the lower exhaust section 1412. Thus, the two duct cavities 141 can be centrally symmetrical about the central axis of the indoor ventilation wheel 142. Figure 21 and Figure 24 In the example, the first direction is horizontal and the second direction is vertical. The diffuser section 1410 is connected to the ventilation wheel cavity 140 on one side in the vertical direction and is connected to the corresponding exhaust section 1412 in the horizontal direction. Taking the first direction as left-right and the second direction as up-down as an example, the upper diffuser section 1410 is connected to the upper side of the ventilation wheel cavity 140 and extends to the right along the airflow direction to connect with the exhaust section 1412 on the right side. The lower diffuser section 1410 is connected to the lower side of the ventilation wheel cavity 140 and extends to the left along the airflow direction to connect with the exhaust section 1412 on the left side.

[0093] In other embodiments, the air duct cavity 141 may be three or more, and the three or more air duct cavities 141 may be rotationally symmetrical about the central axis of the indoor air duct 142. Taking four air duct cavities 141 as an example, each air duct cavity 141 includes a diffusion section 1410 and an exhaust section 1412. The front air outlet area 1200 includes four front air outlets 1202, which are two first front air outlets 1202a and two second front air outlets 1202b, respectively. The two exhaust sections 1412 are arranged vertically at intervals and are respectively connected to the two first front air outlets 1202a. The other two exhaust sections 1412 are arranged horizontally at intervals and are respectively connected to the two second front air outlets 1202b. Of course, the front air outlet area 1200 may also be formed as a ring area.

[0094] like Figure 5 , Figure 16 and Figure 17 As shown, in some embodiments, the side wall of the indoor unit housing 12 opposite to the outdoor unit component 20 includes a first wall portion 124 and a second wall portion 125, the thickness of the first wall portion 124 (e.g., ...) Figure 17 d1) is less than the thickness of the second wall portion 125 (e.g. Figure 17 In the case of d2), a display module 17 is provided on the back side of the first wall portion 124. The display module 17 is located inside the indoor unit housing 12, and the front air outlet area 1200 is formed on the second wall portion 125. By setting the display module 17 on the thinner first wall portion 124, the display module 17 can be displayed on the side wall of the indoor unit housing 12. For example, the display module 17 includes a circuit board and an LED light source. The thinner first wall portion 124 allows the LED light source to be displayed through the first wall portion 124, thereby enhancing the display performance of the display module 17 and making it easier for users to observe the display information of the window air conditioner 1.

[0095] The display module 17 is located within the mounting cavity 145 (e.g., Figure 4 As shown), by placing both the drive motor 146 and the display module 17 within the mounting cavity 145, the display module 17 can make fuller use of the space within the mounting cavity 145, resulting in a more compact structure for the window air conditioner 1 and facilitating its miniaturization. Of course, in other embodiments of this application, the display module 17 can also be located on the outer periphery of the mounting cavity 145 (e.g., Figure 16 As shown, the display module 17 and the drive motor 146 are spaced apart to facilitate the maintenance of the display module 17.

[0096] For example, such as Figure 1 and Figure 4As shown, the display module 17 is located within the mounting cavity 145. The front air outlet area 1200 includes two first front air outlets 1202a spaced apart vertically along the window-type air conditioner 1. The display module 17 is located between the two first front air outlets 1202a, or as shown in the figure. Figure 14 and Figure 16 As shown, the display module 17 is located on the outer periphery of the mounting cavity 145. The front air outlet area 1200 includes two second front air outlets 1202b spaced apart in the left and right direction along the window air conditioner 1. The display module 17 is located on one side 1202b of one of the second front air outlets 1202b away from the other second front air outlet.

[0097] like Figure 5 , Figure 18 , Figures 25-27 As shown, in some embodiments, the indoor unit component 10 further includes a filter assembly 18, which is located in the air inlet area 122 and can filter the airflow flowing from the air inlet area 122 into the indoor unit housing 12.

[0098] The filter assembly 18 is removably mounted on the indoor unit housing 12 to ensure cleaner airflow into the indoor unit components 10. The removable mounting and disassembly simplifies the installation and removal process, improving installation and maintenance efficiency. Since the filter assembly 18 is located outside the air intake area 122, the airflow is filtered by the filter assembly 18 before flowing into the indoor unit housing 12 via the air intake area 122. This eliminates the need for separate processing of the filter assembly on the indoor unit housing 12. The 18-pull-out opening eliminates the need for sealing at the opening, and the interior of the unit housing 12 requires no space for the filter assembly 18. Furthermore, the pull-out installation of the filter assembly 18 will not affect other components within the unit housing 12. And / or, the filter assembly 18 includes a filter support 180, a first filter 181, a second filter 182, and a filter cover 183. The filter support 180 has a windward side 1800 and a leeward side 1802 arranged opposite each other along the airflow direction. The filter support 180 defines... A receiving groove 1804, with its outlet facing the leeward side 1802, accommodates a first filter screen 181. A filter screen cover 183 covers the opening of the receiving groove 1804 to make the first filter screen 181 more stable in its position within the receiving groove 1804. A second filter screen 182 is fixed to one end of the filter support 180 on the windward side 1800, and the first filter screen 181 and the second filter screen 182 are separated by the filter support 180. This facilitates improving the assembly efficiency of the filter assembly 18, for example, by first assembling... The second filter 182 is fixed to one end of the filter support 180 on the windward side 1800. The first filter 181 is then installed in the receiving groove 1804. Finally, the filter cover 183 is placed over the opening of the receiving groove 1804, completing the assembly of the filter assembly 18. By sequentially arranging the second filter 182 and the first filter 181 along the airflow direction, the airflow can be filtered through the second filter 182 and the first filter 181 in sequence, thus improving the cleanliness of the airflow entering the indoor unit 10. For example, the first filter 181 can be a manganese mesh, and the second filter 182 can be a HEPA mesh.

[0099] like Figure 5 and Figure 18 As shown, in some embodiments, the filter assembly 18 is located outside the air inlet area 122, and the indoor unit housing 12 has two spaced-apart pull-out portions 126 extending outward from the air inlet area 122, so that the disassembly and installation of the filter assembly 18 is not easily interfered with by the indoor unit housing 12, and the maintenance efficiency of the filter assembly 18 is improved.

[0100] Each pull-out section 126 defines a pull-out groove 1260 that slides and engages with the filter assembly 18. The openings of the two pull-out grooves 1260 are arranged opposite each other. When the filter assembly 18 is disassembled and installed, the pull-out groove 1260 provides a clear movement path for the filter assembly 18, which allows the filter assembly 18 to move smoothly and accurately relative to the pull-out section 126 along the pull-out direction without deviating from the pull-out groove 1260. This helps to improve the installation efficiency of the filter assembly 18. At the same time, the pull-out groove 1260 can limit the movement range of the filter assembly 18. The filter assembly 18 can only move within the range of the pull-out groove 1260, which helps to reduce the possibility of misalignment of the filter assembly 18 during movement, so that the setting position of the filter assembly 18 can be more stable and the filter assembly 18 can have a stable working effect.

[0101] like Figure 4 and Figure 16 As shown, in some embodiments, the indoor fan 142 is a centrifugal fan, and the first filter 181 is an ultra-clean filter. The indoor fan 142 and the first filter 181 are arranged opposite each other along the air inlet direction of the centrifugal fan. By setting the first filter 181 as an ultra-clean filter (e.g., an ULPA filter), the first filter 181 has extremely high filtration efficiency for fine particulate matter in the air, capable of removing particles of 0.1 micrometers and above, with a filtration efficiency of over 99.999%, thereby improving the cleanliness of the airflow entering the indoor unit 10. At the same time, setting the indoor fan 142 as a centrifugal fan, which has high static pressure resistance, allows the airflow to pass through the ultra-clean filter more smoothly, facilitating the improvement of the stability of the window air conditioner 1.

[0102] like Figures 1-5 , Figures 13-16 and Figure 18 As shown, in some embodiments, the window air conditioner 1 further includes a connecting component 30 adapted to pass through the window. The connecting component 30, the indoor unit component 10, and the outdoor unit component 20 form a receiving space 32 suitable for avoiding the wall or window sash at the window location. For example, the connecting component 30 may include a chassis, with the indoor unit component 10 and the outdoor unit component 20 integrated and mounted on the chassis. The indoor unit component 10 and the outdoor unit component 20 are spaced apart to define the receiving space 32, so that the window air conditioner 1 is constructed as a whole, facilitating assembly. The air inlet area 122 is positioned relative to the air outlet area 120, closer to the receiving space 32.

[0103] As can be seen, the indoor unit 10 and the outdoor unit 20 are separated by the connecting member 30 to define the accommodating space 32. For example, the top, left, and right sides of the accommodating space 32 are respectively open (e.g., Figure 2As shown), the accommodating space 32 can be used to avoid the window sash. For example, if the bottom, left and right sides of the accommodating space 30 are open, the accommodating space 32 can be used to avoid the wall. In this case, the window air conditioner 1 can be formed in a saddle shape. Therefore, the arrangement of the accommodating space 32 can use the wall or window sash to block the noise of the outdoor unit component 20. The air inlet area 122 is positioned close to the accommodating space 32 relative to the air outlet area 120, resulting in a large spatial distance between the air inlet area 122 and the air outlet area 120 and their orientation in different directions. The airflow enters the indoor unit 10 through the air inlet area 122 near the accommodating space 32, is processed by the window air conditioner 1, and is then blown into the room by the air outlet area 120. This reduces the possibility of cross-flow of the air inlet and outlet. Furthermore, the air inlet area 122 allows for a larger space to be allocated to the air outlet area 120, so that the air outlet area 120 is relatively far from the wall when it exits the air, which facilitates the diffusion of the air outlet area 120 into the room. This allows the airflow processed by the window air conditioner 1 to fully diffuse and exchange heat in the indoor space, thereby improving the cooling and heating effects of the window air conditioner 1.

[0104] It is understood that in the above-described scheme of this application, the location of the air intake area 122 is not limited. For example, the air intake area 122 may be located at least partially on the rear side of the indoor unit component 10, or the air intake area 120 may be located on the periphery of the indoor unit component 10.

[0105] like Figures 1-5 , Figures 13-16 and Figure 18As shown, in some embodiments, the air intake area 122 includes a rear air intake area 1220 formed on the side wall of the indoor unit housing 12 facing the outdoor unit component 20. The side wall of the indoor unit housing 12 facing the outdoor unit component 12 is not suitable for setting up the air outlet area 120. This arrangement utilizes the side wall of the indoor unit housing 12 that is unsuitable for setting up the air outlet area 120 to set up the rear air intake area 1220, without restricting the setting of the air outlet area 120. Simultaneously, the rear air intake arrangement helps to reduce the opening area of ​​the indoor unit housing 12 facing the room, allowing the duct assembly 14 to transmit some noise to the outside through the rear air intake area 1220, thus reducing the impact of the indoor unit component 10's noise on the indoor environment. Furthermore, the rear air intake area 1220 is connected to the front air outlet area 1200 through the duct assembly 14, and the rear air intake area 1220 and the front air outlet area 1200 can be opposite each other or staggered, which helps to simplify the structure of the air duct inside the indoor unit housing 12 and reduce the number of bends in the air duct. It is understandable that the rear air intake area 1220 is set towards the receiving space 32. For example, the top, left and right sides of the receiving space 32 are open respectively. The receiving space 32 is used to accommodate the window sash so that the window sash is located between the indoor unit component 10 and the outdoor unit component 20. After the window sash slides down, there is still a certain gap between the window sash and the side wall where the rear air intake area 1220 is located, so that the window sash does not easily affect the normal air intake of the rear air intake area 1220. For another example, the bottom, left and right sides of the receiving space 30 are open respectively. The receiving space 32 is used to avoid the wall so that the wall is located between the indoor unit component 10 and the outdoor unit component 20. After the window air conditioner 1 is installed on the wall, there is still a certain gap between the wall and the side wall where the rear air intake area 1220 is located, which also does not easily affect the normal air intake of the rear air intake area, which helps to improve the stability of the window air conditioner 1.

[0106] For example, the indoor fan 142 is a centrifugal fan, and the central axis of the centrifugal fan extends along the direction from the indoor unit component 10 toward the outdoor unit component 20, so that the air inlet side of the centrifugal fan is set toward the rear air inlet area 1220. The airflow direction after passing through the rear air inlet area 1220 is consistent with the air inlet direction of the centrifugal fan. The air duct cavity 141 is connected to the periphery of the fan wheel cavity 140. The connection position between the air duct cavity 141 and the fan wheel cavity 140 can be located on the air outlet side of the centrifugal fan or adjacent to the air outlet side of the centrifugal fan. Obviously, the relative layout of the rear air inlet area 1220, the fan wheel cavity 140, and the air duct cavity 141 is well matched with the air inlet and outlet mode of the centrifugal fan, which facilitates the improvement of the air inlet and outlet efficiency of the window air conditioner 1.

[0107] For example, the air intake area 122 includes only the rear air intake area 1220, and the air outlet area 120 includes only the front air outlet area 1200; or the air intake area 122 includes the rear air intake area 1220 and the side air intake area, and the air outlet area 120 includes only the front air outlet area 1200.

[0108] like Figure 5 and Figure 18 As shown, in some embodiments, the indoor unit component 10 further includes an indoor heat exchanger 19 and a base 11. The indoor heat exchanger 19 is disposed between the rear air intake area 1220 and the impeller cavity 140. At least a portion of the base 11 is disposed within the indoor unit housing 12, and the aforementioned at least portion of the base 11 is supported on the bottom of the indoor heat exchanger 19 and the air duct assembly 14. A water collection groove 110 corresponding to the indoor heat exchanger 19 is formed on the base 11. Optionally, the base 11 is made of a material with high thermal insulation performance, so that the condensate in the water collection groove 110 is less likely to exchange heat with the external environment, reducing the possibility of condensation forming on the outer periphery of the base 11 and improving the operational stability of the window air conditioner 1.

[0109] For example, the airflow enters the indoor unit component 10 through the rear air intake area 1220, exchanges heat with the indoor heat exchanger 19, and then enters the fan wheel cavity 140. The processed airflow is then blown out through the front air outlet area 1200. At this time, the airflow path of the indoor air circulation does not cross or overlap, and the airflow direction of the intake airflow and the airflow direction are generally in the same direction. This airflow path of the indoor air circulation allows the airflow to enter the heat exchanger more directly and smoothly for heat exchange, and reduces the possibility of airflow short-circuiting and back-suction, thereby improving the heat exchange efficiency and the overall air circulation efficiency.

[0110] In addition, a water receiving tank 110 is provided on the base 11. The water receiving tank 110 can collect the condensate produced by the indoor heat exchanger 19, so that the condensate is not easily leaked to the outside or other components, which helps to improve the stability of the operation of the window air conditioner 1.

[0111] like Figure 5 and Figure 18 As shown, in some embodiments, the water tank 110 has a tank wall located on the side of the indoor heat exchanger 19 facing the air duct assembly 14, and the window air conditioner 1 is configured to satisfy at least one of the following conditions A1 to A4:

[0112] In condition A1, a limiting protrusion 112 is provided on the tank wall. The limiting protrusion 112 is adjacent to one end of the water receiving tank 110 and abuts against one side of the side plate 190 of the indoor heat exchanger 19 in the thickness direction. It can be seen that the limiting protrusion 112 can restrict the displacement of the indoor heat exchanger 19 in the aforementioned thickness direction, so that the indoor heat exchanger 19 can still maintain a preset position under vibration or external force, making it less likely for the indoor heat exchanger 19 and the water receiving tank 110 to misalign, thus improving the operational stability of the window air conditioner 1. Furthermore, the limiting protrusion 112 can serve as a reference point during installation, helping workers to more accurately position the indoor heat exchanger 19, improving the assembly efficiency of the indoor heat exchanger 19 and the base 11, and facilitating the large-scale production of the window air conditioner 1.

[0113] In condition A2, a guide channel 114 is also formed on the base 11, connecting the receiving space 32 and the water receiving tank 110. The guide channel 114 is located at one end of the indoor heat exchanger 19 and is bent and connected to the water receiving tank 110. The tank wall is provided with guide ribs 116, which extend obliquely toward the guide channel 114 to guide the water in the water receiving tank 110 to the guide channel 114. It can be seen that by setting the guide ribs 116, the condensate can be guided from the water receiving tank 110 to the guide channel 114, and the guide channel 114 then guides the condensate to the receiving space 32 for discharge, so that the flow path of the condensate is clearer and the condensate is less likely to leak to other components, thereby improving the operational stability of the window air conditioner 1.

[0114] In condition A3, the side of the duct assembly 14 facing the indoor heat exchanger 19 has a protruding rib 147 extending towards the indoor heat exchanger 19, and the groove wall is supported on the underside of the protruding rib 147. It is evident that the presence of the protruding rib 147 provides an additional positioning reference for the installation process, making the installation of the duct assembly 14 and the base 11 more convenient and faster. Workers can more easily align and fix the duct assembly 14 onto the base 11, thereby shortening the assembly time of the window air conditioner 1 and reducing the assembly difficulty, which is beneficial for the large-scale production and manufacturing of the window air conditioner 1.

[0115] In some embodiments, the indoor unit housing 12 includes a front housing 42 and a rear housing 44, which close together to define an installation space. An indoor heat exchanger 19 and an air duct assembly 14 are both disposed within the installation space, and are arranged sequentially along the airflow direction. A front air outlet region 1200 is located on the side wall of the front housing 42 facing away from the outdoor unit components, and a rear air inlet region 1220 is located on the side wall of the rear housing 44 facing the outdoor unit components, so that the front air outlet region 1200 and the rear air inlet region 1220 are positioned so that the front air outlet region 1200 and the rear air inlet region 1220 are positioned on the side wall of the rear housing 44 facing the outdoor unit components. The regions 1220 are arranged opposite each other. The rear housing 44 also has two pull-out sections 126 that are spaced apart and extend outward from the rear air intake region 1220. Each pull-out section 126 defines a pull-out groove 1260. The filter assembly 18 is slidably fitted into the pull-out groove 1260. After the airflow is purified by the filter assembly 18, it is drawn in from the rear air intake region 1220, heat is exchanged through the indoor heat exchanger 19, and finally it is guided by the air duct assembly 14 to the front air outlet region 1220 and blown into the room, which helps to improve the stability of the window air conditioner 1.
