Description

Technical Field

[0002] In window air conditioners of related technologies, the air inlet and air outlet areas of the indoor unit are both located on the front surface and are close to each other. This causes the airflow processed by the air conditioner to be drawn back into the air inlet area before it can be fully diffused and exchanged for heat, resulting in a short-circuit problem of return air and reducing the temperature regulation effect.

[0054] 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0055] 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.

[0056] Hereinafter, with reference to the accompanying drawings, a window air conditioner 100 according to an embodiment of the present invention will be described.

[0057] See Figure 1 or Figure 10 The window air conditioner 100 includes an indoor unit 1 suitable for installation on the indoor side, an outdoor unit 2 suitable for installation on the outdoor side, and a connecting member 3 suitable for installation through a window. The connecting member 3 forms a receiving space 4 with the indoor unit 1 and the outdoor unit 2 to avoid the wall or window sash at the window. The air inlet area 17 of the indoor unit 1 is located close to the receiving space 4 relative to the air outlet area 18 of the indoor unit 1.

[0058] In window air conditioners of related technologies, the air inlet and air outlet areas of the indoor unit are both located on the front surface and are close to each other. This causes the airflow processed by the air conditioner to be drawn back into the air inlet area before it can be fully diffused and exchanged for heat, resulting in a short-circuit problem of return air and reducing the temperature regulation effect.

[0059] In the technical solution of this application, the connecting component 3 forms a receiving space 4 between the indoor unit component 1 and the outdoor unit component 2 to avoid the wall or window sash at the window. By setting the air inlet area 17 close to the receiving space 4 relative to the air outlet area 18, the air inlet area 17 can make room for a larger space to set the air outlet area 18, so that the air outlet area 18 can be relatively far away from the wall to facilitate the air outlet to diffuse into the room. Moreover, the airflow blown into the room through the air outlet area 18 is not easy to flow back to the air inlet area 17 which is relatively close to the wall, thereby helping to improve the problem of short-circuiting of return air. This allows the airflow processed by the air conditioner to fully diffuse and exchange heat in the indoor space, improving the temperature regulation effect of the air conditioner.

[0060] In the embodiments of this application, the type of window air conditioner 100 is not limited. For example, the window air conditioner 100 can be a cooling-only / heating-only window air conditioner 100 or a heat pump type window air conditioner 100. In addition, the layout of the key components of the window air conditioner 100 is not limited. For example, the window air conditioner 100 can be a window air conditioner 100 with the compressor built into the indoor unit 1, a window air conditioner 100 with the compressor built into the outdoor unit 2, or a window air conditioner with the compressor externally mounted.

[0061] In the embodiments of this application, the arrangement of the air inlet area 17 and the air outlet area 18 is not limited. For example, the air inlet area 17 may be located at least partially on the rear side of the indoor unit 1, and the air outlet area 18 may be located on the front side of the indoor unit 1 facing the room, or the air outlet area 18 may be located on the periphery of the indoor unit 1, etc. The air outlet area 18 may also be arranged in other forms around the center of the air duct, and is not limited to the simple layout of being located on the upper, lower, left, right and any combination thereof of the indoor unit 1.

[0062] In some embodiments, see Figure 1 or Figure 10 The housing space 4 is located on the rear side of the indoor unit 1, and at least a portion of the air intake area 17 is located on the rear side of the indoor unit 1, so as to be arranged toward the housing space 4.

[0063] In the above technical solution, by setting at least a portion of the air inlet area 17 on the rear side of the indoor unit 1 and facing the accommodating space 4, the settling range of the air inlet area 17 is greatly increased. This increases the area of ​​the air inlet area 17 and the flexibility of its setting position. From another perspective, the portion of the air inlet area 17 located on the rear side of the indoor unit 1 does not need to be on the same side as the air outlet area 18, which also frees up space for the setting of the air outlet area 18 and increases the area of ​​the air outlet area 18 and the flexibility of its setting position. Thus, the air inlet area 17 can be set away from the air outlet area 18, and the airflow blown into the room from the air outlet area 18 is less likely to directly enter the air inlet area 17, which helps to improve the problem of return air short circuit. This allows the airflow processed by the air conditioner to fully diffuse and exchange heat in the indoor space, improving the temperature regulation effect of the air conditioner.

[0064] Furthermore, positioning at least a portion of the air intake area 17 at the rear of the indoor unit 1 helps reduce the impact of air conditioner operating noise on the indoor environment. Since noise sources such as fans are typically located inside the indoor unit 1, positioning the air intake area 17 towards the housing space 4 reduces the opening area of ​​the indoor unit 1 towards the room and directs some noise outdoors, thereby reducing the indoor noise level.

[0065] In the embodiments of this application, "at least partially located on the rear side" means that part or all of the air intake area 17 can be located on the rear side of the indoor unit component 1, and the specific proportion and layout depend on the overall design and performance requirements of the air conditioner. For example, the air intake area 17 can be a complete rear side, or it can be a part of the rear side plus parts of other sides.

[0066] In the embodiments of this application, "oriented toward the receiving space 4" means that the opening of the air intake area 17 or the airflow direction mainly points toward the receiving space 4, and does not mean that the air intake area 17 must completely fit the boundary of the receiving space 4. The air intake area 17 can have a certain angle or offset, as long as it can guide air from the receiving space 4 into the indoor unit 1.

[0067] In the embodiments of this application, the layout of the key components of the window air conditioner 100 is not limited. For example, the positions of the heat exchanger 12 and the fan 13 are not limited. For example, the air inlet surface of the heat exchanger 12 can be arranged facing the accommodating space 4 or perpendicular to the accommodating space 4; the fan 13 can be located on the side of the heat exchanger 12 away from the accommodating space 4 or on the side of the heat exchanger 12 close to the accommodating space 4.

[0068] In some embodiments, see Figures 2-4 or Figures 11-13 The indoor unit 1 includes a housing 11, a heat exchanger 12, and a fan 13. Both the heat exchanger 12 and the fan 13 are housed within the housing 11, with the heat exchanger 12 located behind the fan 13. The air inlet area 17 includes a rear air inlet 1711, which is located at the rear of the housing 11 and behind the heat exchanger 12, so that the air inlet area 17 includes a rear air inlet area 171 located behind the heat exchanger 12. Therefore, the indoor air circulation path is as follows: return air enters the indoor unit 1 through the air inlet area 17 facing the accommodating space 4, exchanges heat with the heat exchanger 12, and then enters the fan 13. The treated airflow is then blown out through the air outlet area 18 on the housing 11. At this time, the air circulation path of the indoor air does not cross or overlap, and the air intake and exhaust air flows in roughly the same direction. This air circulation path of the indoor air allows the air to enter the heat exchanger 12 more directly and smoothly for heat exchange, and reduces the possibility of air short-circuiting and back-suction, thereby improving the heat exchange efficiency and overall air circulation efficiency.

[0069] In addition, the heat exchanger 12 and the fan 13 are integrated into the housing 11, and the design of the rear air inlet 1711 makes the structure of the indoor unit 1 more compact. The rear air inlet 1711 is located at the rear of the housing 11, which reduces the opening of the indoor unit 1 towards the room and directs some noise to the outside, thereby reducing the indoor noise level.

[0070] In the embodiments of this application, the arrangement of the rear air inlet 1711 is not limited. For example, the rear air inlet 1711 can be a large opening, multiple openings, a perforated form, a grille, etc.

[0071] In some embodiments, see Figures 2-4 or Figures 11-13The connecting component 3 connects the bottom of the indoor unit component 1 to the bottom of the outdoor unit component 2, so that the receiving space 4 is located above the connecting component 3. At this time, the window sash can be pulled down into the receiving space 4, and the connecting component 3 is fixedly connected to the wall along the bottom edge of the window. Alternatively, the receiving space 4 can also be located below the connecting component 3, with the wall inside the receiving space 4, and the connecting component 3 is fixedly connected to the wall along the bottom edge of the window, with the window sash located above the connecting component 3. Alternatively, the receiving space 4 can also be located to the left or right of the connecting component 3, with the wall inside the receiving space 4, and the connecting component 3 is fixedly connected to the wall along the side edge of the window, with the window sash sliding horizontally to the left or right of the connecting component 3. Of course, the connecting component 3 can also be fixedly connected to the wall along the left edge of the window, and the window sash can be pushed horizontally into the receiving space 4 from the right side. Or, the connecting component 3 can be fixedly connected to the wall along the right edge of the window, and the window sash can be pushed horizontally into the receiving space 4 from the left side.

[0072] See Figures 4-5 or Figures 13-14 When the connecting component 3 connects the bottom of the indoor unit component 1 and the bottom of the outdoor unit component 2 so that the accommodating space 4 is located above the connecting component 3, the heat exchanger 12 includes an upper heat exchange section 121 and a lower heat exchange section 122. The upper heat exchange section 121 is located above the lower heat exchange section 122 and extends forward and upward from the upper end of the lower heat exchange section 122. The rear air inlet 1711 includes a rear lower air inlet 17112 located behind the lower heat exchange section 122 and a rear upper air inlet 17111 located behind the upper heat exchange section 121.

[0073] In the above technical solution, the upper heat exchange section 121 of the heat exchanger 12 extends forward and upward, increasing the heat exchange area of ​​the heat exchanger 12. This allows the air to exchange heat more fully with the refrigerant when flowing through the heat exchanger 12, thereby enhancing the cooling / heating capacity of the air conditioner. Furthermore, compared to the lower heat exchange section 122 extending forward and downward to increase the heat exchange area, the upward extension of the upper heat exchange section 121 is easier to install and allows for more flexible extension methods, as it is not interfered with by the connecting component 3, further increasing the heat exchange area of ​​the heat exchanger 12.

[0074] In the embodiments of this application, the upper end of the lower heat exchange section 122 extends forward and upward to form the upper heat exchange section 121. The specific extension form is not limited. For example, it can extend along a straight line or along a curve.

[0075] In some embodiments, see Figures 4-5 or Figures 13-14 An air inlet 15 is formed between the casing 11 and the upper heat exchange section 121, located behind the upper heat exchange section 121. The rear upper air inlet 17111 is located behind the air inlet 15. (See also...) Figures 5-7 or Figures 14-16The housing 11 has an upper air inlet 1721 formed on the top of the housing 11 above the air inlet cavity 15, so that the air inlet area 17 includes an upper air inlet area 172 above the air inlet cavity 15; and / or, the housing 11 has a side air inlet 1731 formed on the side of the housing 11, located on at least one side of the air inlet cavity 15, so that the air inlet area 17 includes a side air inlet area 173 located on the side of the air inlet cavity 15.

[0076] In the above technical solution, by setting the air inlet cavity 15, the left and right side plates and the rear plate surrounding the shell 11 can all be rectangular plates, which facilitates production and processing, makes assembly easier, reduces assembly gaps, and increases assembly precision. The air inlet cavity 15 formed between the shell 11 and the upper heat exchange section 121 provides an additional airflow channel, increases the upper air inlet space, and reduces the obstruction of airflow by walls or window sashes, thereby increasing the air intake volume. The air inlet cavity 15 has a guiding effect on airflow, so that the airflow entering the air inlet cavity 15 from all directions flows more evenly through the heat exchanger 12, improving heat exchange efficiency. Furthermore, the arrangement of the upper air inlet 1721 and the side air inlet 1731 further enriches the air intake area 17, allowing air to enter the equipment from multiple directions. When the space between the heat exchanger 12 (especially the lower heat exchange section 122) and the installation environment (such as window sashes, walls) is limited, setting additional air inlets (such as the upper air inlet 1721 and the side air inlet 1731) can significantly enhance the air intake performance of the indoor unit component 1 and improve the heat exchange efficiency.

[0077] In some embodiments, see Figure 8 An open space 16 is formed at the upper rear of the shell 11, meaning that no structure is provided at the upper rear of the shell 11, thus forming an open space 16. The open space 16 is located outside the shell 11 and above the lower heat exchange section 122. The upper rear air inlet 17111 is set close to the upper heat exchange section 121, so as to be located between the open space 16 and the upper heat exchange section 121.

[0078] In the above technical solution, a clearance space 16 is formed at the upper rear of the casing 11, which increases the air intake space at the upper part of the casing 11 and reduces the obstruction of air intake by walls or window sashes, thereby increasing the air intake volume. In addition, the setting of clearance space 16 also increases the flexibility of the setting position of indoor unit component 1. The rear upper air inlet 17111 is set close to the upper heat exchange section 121. The rear upper air inlet 17111 is in close contact with the heat exchanger 12, which allows for smoother flow through the upper heat exchange section 121, reduces flow resistance, and improves heat exchange efficiency. In addition, if a filter screen 14 is set between the air inlet and the heat exchanger 12, the filter screen 14 can be sandwiched between the air inlet and the heat exchanger 12, reducing the setting of filter screen 14 fixing parts, and the structure of indoor unit component 1 is also more compact.

[0079] In some embodiments, see Figure 8The upper heat exchange section 121 extends obliquely upwards along a straight line, or extends obliquely upwards along an upward curved line; see also Figure 9 The lower heat exchange section 122 extends vertically from top to bottom to the bottom of the indoor unit 1, or the lower heat exchange section 122 first extends vertically from top to bottom, and then extends forward and downward along a straight line or curve to the bottom of the indoor unit 1.

[0080] In the above technical solution, the upper heat exchange section 121 extends obliquely forward from bottom to top along a straight line, increasing the heat exchange area of ​​the heat exchanger 12 and facilitating manufacturing. The upper heat exchange section 121 also extends obliquely forward from bottom to top along an upward curved line, making more efficient use of the space in the indoor unit 1 and further increasing the heat exchange area. The lower heat exchange section 122 first extends vertically from top to bottom, then extends forward and downward along a straight line or curve to the bottom of the indoor unit 1. This allows the airflow to fully exchange heat with the lower heat exchange section 122, reducing the possibility of insufficient heat exchange due to space limitations. Furthermore, the extension methods of the upper and lower heat exchange sections 121 and 122 not only consider heat exchange efficiency but also the structural stability of the equipment. Through a reasonable layout and extension method, the stability and reliability of the equipment during operation are ensured.

[0081] In some embodiments, see Figure 5 or Figure 14 The upper heat exchange section 121 is higher than the center plane M of the indoor unit component 1. Therefore, the proportion of the upper heat exchange section 121 is relatively small. Even if the upper heat exchange section 121 extends forward, its projection on the horizontal plane is also small. Thus, the thickness of the indoor unit component 1 occupied by the upper heat exchange section 121 extending forward is small. In this way, the heat exchange area of ​​the heat exchanger 12 is increased, improving the heat exchange capacity, without significantly increasing the thickness dimension of the indoor unit component 1, making the structure of the indoor unit component 1 more compact.

[0082] In some embodiments, see Figure 5 or Figure 14 The angle α between the line connecting the upper and lower ends of the upper heat exchange section 121 and the horizontal plane is 45°-85°. Therefore, the projection of the upper heat exchange section 121 extending forward onto the horizontal plane is small. This means that the thickness of the indoor unit component 1 occupied by the forward extension of the upper heat exchange section 121 is small. This increases the heat exchange area of ​​the heat exchanger 12, improving its heat exchange capacity, without significantly increasing the thickness of the indoor unit component 1, making the structure of the indoor unit component 1 more compact.

[0083] In some embodiments, see Figure 5 or Figure 14The upper heat exchange section 121 is higher than the center plane M of the indoor unit component 1, and the angle α between the line connecting the upper and lower ends of the upper heat exchange section 121 and the horizontal plane is 45°-85°. As a result, the proportion of the upper heat exchange section 121 is relatively small, and the projection of the upper heat exchange section 121 extending forward onto the horizontal plane is also small. That is, because the upper heat exchange section 121 occupies less thickness of the indoor unit component 1 when extending forward, the heat exchange area of ​​the heat exchanger 12 is increased, thereby improving the heat exchange capacity, without significantly increasing the thickness dimension of the indoor unit component 1, making the structure of the indoor unit component 1 more compact.

[0084] In some embodiments, see Figure 5 or Figure 14 The indoor unit component 1 also includes a filter screen 14, which is located inside the housing 11 and behind the heat exchanger 12. Thus, the filter screen 14, positioned upstream of the heat exchanger 12, can intercept most impurities in the air entering the equipment, helping to keep the surface of the heat exchanger 12 clean, delaying the decline in heat exchange capacity caused by dust and impurities adhering to the heat exchanger 12, extending its service life, and reducing maintenance frequency. Effective filtration by the filter screen 14 reduces the amount of airborne dust entering the equipment, avoiding dust accumulation problems in the indoor unit components 1 (such as fans, motors, etc.), reducing safety hazards such as overheating and short circuits caused by dust accumulation, enhancing the stability and safety of the equipment, and reducing maintenance costs and failure rates.

[0085] In addition, the air filtered by filter 14 is cleaner, which helps improve indoor air quality and provides users with a healthier and more comfortable living environment.

[0086] In some embodiments, see Figure 2 or Figure 11 The indoor unit 1 includes a housing 11, a heat exchanger 12, and a fan 13. Both the heat exchanger 12 and the fan 13 are housed within the housing 11. The heat exchanger 12 is located behind the fan 13. The housing 11 includes a front portion 111 located in front of the heat exchanger 12, and an air outlet area 18 is located in the front portion 111. By arranging the air outlet area 18 in the front portion 111, with each surface of the front portion 111 facing the interior, it is ensured that the air after heat exchange can flow smoothly in all directions within the room, thereby helping to reduce airflow resistance and improve air delivery efficiency.

[0087] In the embodiments of this application, the form of the air outlet area 18 is not limited. The air outlet area 18 may be located on the front side of the front part 111 of the housing to face the room, or the air outlet area 18 may be located on the periphery of the front part 111 of the housing, etc. The air outlet area 18 may also be arranged in other forms around the center of the air duct, and is not limited to the simple layout of being located on the upper, lower, left, right and any combination thereof on the front part 111 of the housing.

[0088] In the embodiments of this application, the specific form of the housing 11 is not limited. For example, the housing 11 can be an integral housing 11, that is, the housing 11 can be a one-piece molded part, i.e., made of a single material without any detachable parts, resulting in higher overall structural strength; the housing 11 can also include multiple parts, for example, such as... Figure 2 and Figure 11 As shown, the housing 11 is divided into a front part 111 and a rear part 112. The front part 111 and the rear part 112 can be processed separately during the manufacturing process, but they are tightly joined together by a fixed connection process (such as bonding, welding, etc.) to form an inseparable whole.

[0089] In some embodiments, see Figure 5 or Figure 14 The fan 13 is a cross-flow fan 13a with its axis extending in the left-right direction. The air outlet area 18 is located in the upper front or lower front part of the casing 11, and the outlet of the fan 13 extends toward the air outlet area 18. The streamlined blades and smooth airflow channel of the cross-flow fan 13a allow airflow to pass smoothly through the fan 13, reducing the possibility of airflow turbulence and eddy current generation, thereby reducing aerodynamic noise. The outlet of the fan 13 extends toward the air outlet area 18, ensuring that the airflow can flow out directly and efficiently, reducing the turning and collision of airflow within the casing 11, and further reducing noise generation.

[0090] By setting the air outlet area 18 at the upper front or lower front part of the housing 11, the air supply direction can be flexibly adjusted according to actual needs to meet the usage requirements of different scenarios. At the same time, it also helps to reduce the air flow resistance in the housing 11 and improve the air supply efficiency.

[0091] In some embodiments, see Figures 5-7 The air outlet area 18 is higher than the height center plane of the housing 11, and includes a front upper air outlet 181 located on the upper front side of the housing 11 and / or a front top air outlet 182 located on the front top side of the housing 11.

[0092] In the above technical solution, positioning the air outlet area 18 at a higher position on the casing 11 facilitates the formation of a downward airflow. This airflow pattern can more effectively cover the indoor space in most cases, especially when the air conditioner is in cooling mode. Because the density of cold air is greater than that of indoor air, the blown cold air tends to move downwards. Positioning the air outlet area 18 at the upper front of the casing 11 allows the cold air to mix and exchange heat more thoroughly with the indoor air, thereby improving the cooling response speed and the uniformity of temperature distribution. Furthermore, positioning the air outlet at a higher position on the casing 11 avoids obstacles near the ground, ensuring smooth airflow. For occupants, a higher position on the casing 11 reduces direct airflow onto their faces, improving user comfort.

[0093] The air outlet area 18 includes a front upper air outlet 181 and a front top air outlet 182, which can meet the air supply needs of different heights and angles respectively. This increases the area and direction of the air outlet area 18, making the air supply softer and improving the flexibility and targeting of the air supply.

[0094] In some embodiments, see Figure 5 The heat exchanger 12 includes an upper heat exchange section 121 and a lower heat exchange section 122. The upper heat exchange section 121 is located above the lower heat exchange section 122, which extends vertically in the vertical direction. The upper heat exchange section 121 extends forward and upward from the upper end of the lower heat exchange section 122. The fan 13 is located in front of the lower heat exchange section 122 and is lower than the upper heat exchange section 121. Therefore, the position of the fan 13 will not interfere with the upper heat exchange section 121 extending forward and upward, making the layout of key components in the indoor unit 1 more compact and reducing the size of the indoor unit 1. Combined with the fact that the air outlet area 18 is located in the upper front part of the housing 11, and the fan 13 is located in front of the lower heat exchange section 122 and lower than the upper heat exchange section 121, space is reserved for connecting the air outlet section to the upper air outlet area 18. The air outlet section can better guide the airflow, making the airflow direction and velocity more uniform, thereby improving the comfort of the air conditioner.

[0095] In some embodiments, see Figures 14-16 The air outlet area 18 is lower than the height center plane of the housing 11, and includes a front lower air outlet 183 located at the lower front side of the housing 11 and / or a front bottom air outlet 184 located at the front bottom side of the housing 11.

[0096] In the above technical solution, placing the air outlet area 18 at a lower position on the casing 11 ensures that the airflow can cover lower spatial areas. This is particularly useful for scenarios requiring rapid cooling or heating of lower spatial areas, such as areas near the ground. When the air conditioner is in heating mode, because the density of hot air is less than that of indoor air, the blown hot air tends to rise. The air outlet area 18, located at the lower front part of the casing 11, allows the hot air to mix and exchange heat more thoroughly with the indoor air, thereby improving the heating response speed and the uniformity of temperature distribution.

[0097] The air outlet area 18 includes a front lower air outlet 183 and a front bottom air outlet 184, which can respectively meet the air supply needs at different heights and angles. This increases the area and direction of the air outlet 18, making the airflow gentler and improving the flexibility and targeting of the air supply. For example, the front lower air outlet 183 is located at the lower front side of the housing 11, which facilitates direct air supply to the front and lower, and is suitable for scenarios that require rapid heating of the ground or to provide localized comfortable airflow, such as winter heating. The front bottom air outlet 184 is located at the front bottom side of the housing 11, which can more effectively supply air to the vicinity of the ground, and is particularly suitable for occasions that require uniform heating or cooling of the space near the ground, such as homes and offices.

[0098] In some embodiments, see Figure 14 The heat exchanger 12 includes an upper heat exchange section 121 and a lower heat exchange section 122. The upper heat exchange section 121 is located above the lower heat exchange section 122, which extends vertically in the vertical direction. The upper heat exchange section 121 extends forward and upward from the upper end of the lower heat exchange section 122. The fan 13 is located in front of the intersection of the lower heat exchange section 122 and the upper heat exchange section 121. This fully utilizes the lower space of the upper heat exchange section 121 extending forward and upward, improving the compactness and integration of the equipment and reducing the size of the indoor unit components 1. Combined with the air outlet area 18 being located at the lower front of the housing 11, and the fan 13 being located in front of the intersection of the lower heat exchange section 122 and the upper heat exchange section 121, space is reserved for connecting the air outlet section to the lower air outlet area 18. The air outlet section can better guide the airflow, making the airflow direction and velocity more uniform, thereby improving the comfort of the air conditioner.

[0099] In some embodiments, see Figure 5 The front of the housing 11 has a front panel 1111, and the air outlet area 18 is positioned above the front panel 1111. This facilitates the formation of a downward airflow, which in most cases can more effectively cover the indoor space, especially when the air conditioner is in cooling mode. Because the density of cold air is greater than that of indoor air, the blown cold air tends to move downwards. The fact that area 18 is positioned above the front panel 1111 allows the cold air to mix and exchange heat more fully with the indoor air, thereby improving the cooling response speed and the uniformity of temperature distribution. In addition, positioning the air outlet at a higher position on the housing 11 avoids obstacles near the ground, ensuring smooth airflow. For people indoors, the higher position of the air outlet on the housing 11 reduces direct airflow onto their faces, improving user comfort.

[0100] In some embodiments, see Figure 14The front side of the housing 11 has a front panel portion 1111, and the air outlet area 18 is positioned below the front panel portion 1111. This ensures that airflow can cover lower spatial areas, which is particularly useful in scenarios requiring rapid cooling or heating of lower spaces, such as areas near the ground. When the air conditioner is in heating mode, because the density of hot air is less than that of indoor air, the blown hot air tends to rise. The air outlet area 18 being positioned below the front panel portion 1111 allows the hot air to mix and exchange heat more thoroughly with the indoor air, thereby improving the heating response speed and the uniformity of temperature distribution.

[0101] In some embodiments, see Figure 9 The front side of the housing 11 has a front panel 1111. The air outlet area 18 is divided into an upper air outlet area 18U and a lower air outlet area 18D. The upper air outlet area 18U is set higher than the front panel 1111, and the lower air outlet area 18D is set lower than the front panel 1111. As a result, the airflow blown out by the air outlet area 18 can cover both higher and lower spatial areas, thereby enabling rapid mixing and heat exchange with indoor air at various heights, thus improving the cooling response speed and the uniformity of temperature distribution.

[0102] In some embodiments, see Figure 5 or Figure 9 or Figure 14 The front panel portion 1111 has a vertical dimension H that is greater than half the height X of the housing 11, and the front panel portion 1111 does not have a ventilation area but has a display panel DP.

[0103] In the above technical solution, the front panel 1111 is larger than half the height of the housing 11 in the vertical direction. This means that the front panel 1111 is the main component of the front side of the housing 11 and occupies a large visible area. Combined with the fact that the front panel 1111 does not have a ventilation area, the indoor unit 1 will not have large openings or grilles in the user's field of vision, making the appearance of the equipment cleaner and more beautiful. At the same time, the front panel 1111 in the user's field of vision is equipped with a display panel DP, which can be used to display key information such as the operating status of the equipment, temperature, and humidity, or to control the operation of the equipment. The integration of the display panel DP allows the user to intuitively understand the status of the equipment and perform necessary operations, which not only improves the operability and convenience of the window air conditioner 100, but also enhances the technological feel of the equipment.

[0111] Hereinafter, with reference to the accompanying drawings, a window air conditioner 100 according to a specific embodiment of the present invention will be described.

[0112] See Figure 10 and Figure 11 According to a specific embodiment of the present invention, a window air conditioner 100 includes an indoor unit component 1 suitable for installation on the indoor side, an outdoor unit component 2 suitable for installation on the outdoor side, and a connecting component 3 suitable for installation through a window.

[0113] See Figure 14 The indoor unit component 1 includes a housing 11, a heat exchanger 12, and a fan 13. Both the heat exchanger 12 and the fan 13 are located inside the housing 11. The heat exchanger 12 is located behind the fan 13. The heat exchanger 12 includes an upper heat exchange section 121 and a lower heat exchange section 122. The upper heat exchange section 121 is located above the lower heat exchange section 122 and extends forward and upward from the upper end of the lower heat exchange section 122. An air inlet cavity 15 is formed between the housing 11 and the upper heat exchange section 121, located behind the upper heat exchange section 121.

[0114] See Figures 14-16The air inlet area 17 includes a rear air inlet area 171, an upper air inlet area 172, and a side air inlet area 173. The rear air inlet area 171 includes a rear air inlet 1711, which is located at the rear of the housing 11 and behind the heat exchanger 12. The rear air inlet 1711 includes a rear lower air inlet 17112 located behind the lower heat exchange section 122 and a rear upper air inlet 17111 located behind the upper heat exchange section 121, so that... The air inlet area 17 includes a rear air inlet area 171 located behind the heat exchanger 12; the top of the housing 11 forms an upper air inlet 1721 located above the air inlet cavity 15, so that the air inlet area 17 includes an upper air inlet area 172 located above the air inlet cavity 15; the side of the housing 11 forms side air inlets 1731 located on the left and right sides of the air inlet cavity 15, so that the air inlet area 17 includes a side air inlet area 173 located on the side of the air inlet cavity 15.

[0115] See Figure 14 The upper heat exchange section 121 extends obliquely forward from bottom to top along a straight line.

The lower heat exchange section 122 extends vertically from top to bottom to the bottom of the indoor unit 1.

[0116] See Figure 14 The indoor unit component 1 also includes a filter 14, which is located inside the housing 11 and behind the heat exchanger 12. The housing 11 includes a front housing portion 111 located in front of the heat exchanger 12. An air outlet area 18 is located in the front housing portion 111. The front side of the housing 11 has a front panel portion 1111. The air outlet area 18 is set higher or lower than the front panel portion 1111. The front panel portion 1111 has a vertical dimension greater than 1 / 2 of the height of the housing 11. The front panel portion 1111 does not have a ventilation area but has a display panel DP.

[0117] See Figures 14-16 The air outlet area 18 is located at the lower front part of the housing 11. The air outlet area 18 is lower than the height center plane of the housing 11 and includes a lower front air outlet 183 located at the lower front side of the housing 11 and a lower front air outlet 184 located at the front bottom side of the housing 11. The fan 13 is located at the front side of the intersection of the lower heat exchange section 122 and the upper heat exchange section 121. The fan 13 is a cross-flow fan 13a with its axis extending in the left and right direction. The outlet of the fan 13 extends toward the air outlet area 18.

[0118] Existing window air conditioner designs, due to space constraints, typically have an air intake area at the bottom front and an air outlet area at the top. This design leaves a large area for the air intake grille on the front of the unit, severely impacting its appearance. Furthermore, the air outlet area also faces forward, sharing the same space as the intake area, leading to a degree of backflow—meaning the exhaust air is immediately drawn back into the unit, preventing effective indoor heat exchange circulation. This results in very poor cooling and heating performance, especially in heating. Heating requires downward airflow to allow the hot air to move close to the ground, adhering to the principle of low-density, gently rising airflow for optimal comfort. However, the old traditional window unit design, with its air intake grille at the bottom front, causes severe backflow, preventing the heating air from circulating throughout the room, ultimately resulting in a very poor heating experience.

[0119] Even if the air inlet and outlet areas of a traditional window air conditioner are reversed, with the air inlet at the top and the outlet at the bottom, this design does not meet the principle of cooling comfort. This is because the cooling airflow is dense and needs to be directed upwards. If the cooling airflow is directed upwards in this design, it will still cause backflow, which will prevent the cooling and heat exchange cycle from taking place indoors, resulting in a poor cooling experience.

[0120] This utility model provides a window air conditioner 100 with a rear-intake and front-outtake cross-flow duct. It is an integrated air conditioner consisting of an indoor unit 1 and an outdoor unit 2, which are assembled on a connecting component 3. The air intake area of ​​the indoor unit 100 on the indoor side is located in the accommodating space 4 between the indoor unit 1 and the outdoor unit 2, at the rear of the indoor unit 1. An air outlet area 18 is provided on the front part 111 of the casing facing the indoor side of the indoor unit 1. The arrangement of the air outlet area 18 is not limited to a simple vertical or horizontal layout; the air outlet area 18 can be arranged in other forms around the center of the duct.

[0121] The indoor unit 1 and the outdoor unit 2 have a receiving space 4 in the middle for placing the sliding window sash when installing this window air conditioner 100. After the window sash is installed in this receiving space 4, the lower edge of the rear part 112 of the indoor unit 1's housing abuts against the lower edge of the window sash. Then, there is a certain distance between the glass sealing surface of the window sash and the rear part 112 of the housing—that is, the step difference between the edge of the window frame and the glass surface. At this time, the airflow of the indoor environment can enter the filter 14 of the indoor unit 1 through the space between the glass and the rear part 112 of the housing. After purification, the incoming air flows through the heat exchanger 12 to exchange heat and achieve cooling or heating, and then enters the air duct component, which is sent to the air outlet area 18 by the cross-flow fan. The specific direction of the air outlet is controlled by the air guide plate.

[0122] A base is provided on the chassis, and a heat exchanger 12 component is provided at the rear of the base. The rear part of the housing 112 is covered by the heat exchanger 12, and a purification filter 14 is inserted into the rear part of the housing 112. The front side of the heat exchanger 12 is a duct component composed of a rear air duct volute, a cross-flow impeller, and a front air duct volute. The front periphery of the duct component is the front part of the housing 111 and a display panel provided on the front part of the housing 111.

[0123] In specific embodiment 1, the air inlet area 17 is located in part of the rear plate, side plate and top plate of the rear part 112 of the housing, and the air outlet area 18 is located in the upper front part of the front part 111 of the housing, so that the air inlet area 17 and the air outlet area 18 are completely separated, so that when the air is delivered to the front of the whole unit and blown into the room, the influence of the air inlet is minimized, forming a new layout of the window air conditioner 100 that is completely different from the traditional design, solving the problem of short circuit between the air inlet and outlet in the background technology, which causes the air inlet and outlet to cross and affects the heat exchanger 12 and the comfort of the airflow.

[0124] In specific embodiment 2, the air inlet area 17 is located in part of the rear plate, side plate and top plate of the rear part 112 of the housing, and the air outlet area 18 is located in the lower front part of the front part 111 of the housing. This completely separates the air inlet area 17 and the air outlet area 18, minimizing the impact of the air inlet when the air is blown towards the front of the unit and into the room. This creates a new layout for the window air conditioner 100 that is completely different from the traditional design. It also solves the problem of short circuit between the air inlet and outlet in the prior art, which causes the air inlet and outlet to cross and affects the heat exchanger 12 and the comfort of the airflow.

[0125] The window air conditioner 100 with a rear air inlet and front air outlet cross-flow duct proposed in this utility model has the following beneficial effects:

[0126] 1. The air intake area 17 is located on the rear side of the indoor unit component 1, so that the air intake area 17 is not visible to the user. There is no air intake grille on the front appearance visible to the user, and the appearance is exquisite and technological.

[0127] 2. By placing the air inlet area 17 on the rear side of the indoor unit component 1, the problem of cross-flow of air inlet and outlet affecting the heat exchanger 12 and the comfort of the airflow is solved, thus improving the user's airflow comfort experience.

[0128] 3. By placing the air intake area 17 on the rear side of the indoor unit component 1, and by having the air intake area 17 face the outside, the opening area of ​​the indoor unit component 1 facing the room can be reduced, and some noise can be directed to the outside, thereby reducing the indoor noise level.
