Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a window air conditioner and its installation method. Background Technology

[0002] Window air conditioners are a type of integrated air conditioner, where all components—compressor, indoor heat exchanger, outdoor heat exchanger, throttling device, fan, fan blades, piping, electrical box, etc.—are housed within a single casing. Window air conditioners offer advantages such as low price, simple installation, and convenient maintenance. Based on the air outlet method, they are generally divided into top-discharge window air conditioners and side-discharge window air conditioners, with side-discharge window air conditioners being widely used in overseas markets. While window air conditioners offer many advantages, their inherent structural limitations also result in several drawbacks: First, in current side-discharge window air conditioners, the indoor return air and air outlet are on the same side, making it easy for the blown-out cold air to be drawn back into the return air vent, causing cold air recirculation and wasting cooling efficiency. Second, due to the relatively high noise level of window air conditioners, the indoor fan speed cannot be set too high, resulting in a limited airflow and a relatively limited air delivery distance. Third, side-discharge window air conditioners typically use centrifugal fan blades to draw indoor air in through the indoor return air vent, where it exchanges heat with the evaporator before being ejected by the centrifugal fan blades. Because the return and outlet air are on the same side, the air is easily drawn back into the evaporator, leading to a waste of cooling efficiency. The cold air ejected by the fan blades needs to bend 90 degrees before exiting. Poor airflow can increase noise, reduce airflow speed, and shorten the delivery distance. In larger rooms, areas closer to the air conditioner are cooler, while areas further away experience less cooling. Fourth, due to the cold air recirculation and lower temperatures near the air conditioner, the ambient temperature sensor at the return air vent senses a rapid drop in ambient temperature. This causes inverter window air conditioners to reduce compressor operating frequency, and fixed-frequency window air conditioners to shut down when the desired temperature is reached, resulting in a poor cooling experience. Fifth, if... Figure 1 and Figure 2 As shown: Window air conditioners are usually installed on windows, which reduces the amount of natural light in the room. Summary of the Invention

[0003] The present invention provides a window air conditioner and its installation method, which aims to solve at least one of the problems of existing window air conditioners, such as cold air recirculation, short air supply distance, inaccurate temperature sensing, high noise, and impact on lighting.

[0004] This invention provides a window air conditioner, comprising:

[0005] An air conditioner housing includes an indoor housing, on which an indoor air outlet and an indoor air return outlet are provided, wherein the indoor air outlet and the indoor air return outlet are not on the same plane;

[0006] A centrifugal fan blade is disposed in the indoor side housing, with the axial direction of the centrifugal fan blade facing the indoor return air inlet and the circumferential surface of the centrifugal fan blade facing the indoor air outlet.

[0007] In the window air conditioner provided by the present invention, the air conditioner housing further includes an outdoor side housing, which is connected to the back side of the indoor side housing and extends from the back side of the indoor side housing in a direction perpendicular to the indoor side housing.

[0008] In the window air conditioner provided by the present invention, the window air conditioner further includes a compressor, the outdoor housing includes a barrier area, the area of ​​the outdoor housing that is not directly opposite the back of the indoor housing is the barrier area, and the compressor is disposed in the barrier area.

[0009] In the window air conditioner provided by the present invention, the air conditioner housing further includes a base, the indoor housing and the outdoor housing are integrally formed to form a cover, and the cover is placed on the base.

[0010] In the window air conditioner provided by the present invention, the casing includes a continuous top wall, a continuous side wall, an indoor side wall, an outdoor side wall, and an outdoor front wall. The continuous side wall is vertically connected to one side of the continuous top wall. The indoor side wall and the outdoor side wall are vertically connected to the other side of the continuous side wall opposite to the continuous side wall. The distance between the outdoor side wall and the continuous side wall is greater than the distance between the indoor side wall and the continuous side wall. The outdoor front wall is vertically connected to the continuous top wall and connects the indoor side wall and the outdoor side wall. The continuous top wall, the continuous side wall, and the indoor side wall together form the indoor shell, and the continuous top wall, the continuous side wall, the outdoor front wall, and the outdoor side wall together form the outdoor shell.

[0011] In the window air conditioner provided by the present invention, the air conditioner housing further includes an air outlet panel, which is installed on the front side of the integrated top wall, the integrated side wall, and the indoor side wall. The indoor air outlet is opened on the air outlet panel, and the indoor air outlet is provided with an air outlet grille.

[0012] In the window air conditioner provided by the present invention, the indoor air outlet is located on the front of the indoor side shell, and the indoor return air outlet is located on the side of the indoor side shell.

[0013] In the window air conditioner provided by the present invention, the window air conditioner further includes an indoor heat exchanger, which is disposed between the side of the indoor shell and the centrifugal fan blade.

[0014] In the window air conditioner provided by the present invention, the indoor heat exchanger is placed parallel to the side of the indoor housing.

[0015] The present invention also provides an installation method for a window air conditioner, wherein the window air conditioner is the aforementioned window air conditioner, and the method includes:

[0016] Install the indoor shell and the outdoor shell at their vertical connection point near the left or right side of the window in the wall so that the outdoor shell is located on the back of the wall.

[0017] This invention provides a window air conditioner and its installation method. The window air conditioner includes an air conditioner housing and a centrifugal fan. The air conditioner housing includes an indoor side housing, with the indoor air outlet and indoor return air outlet located on different planes of the indoor side housing. This reduces mutual interference between the return and outlet airflows, prevents cold air recirculation, and improves the accuracy of the indoor temperature sensor. The centrifugal fan's axial direction faces the indoor return air outlet, allowing indoor air to enter the indoor side housing from the return air outlet and be drawn in by the centrifugal fan. Under the rotation of the centrifugal fan, the drawn-in air is blown out along the tangential direction of the centrifugal fan's rotation. Since the circumferential surface of the centrifugal fan faces the indoor air outlet, the tangential direction of the centrifugal fan's rotation is consistent with the air outlet's direction, allowing the airflow to blow directly towards the indoor air outlet. This results in lower airflow resistance, smoother airflow, and a longer delivery distance at the same fan speed. The installation method of this window air conditioner involves installing the indoor and outdoor casings at the vertical connection point near the left or right side of the window on the wall, so that the outdoor casing is located on the back of the wall. On the one hand, the noise transmitted by the compressor is blocked by the wall, improving the user experience; on the other hand, by installing it close to one side of the wall, the window exposes a larger area for light, increasing the indoor illuminance.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrating and understanding this invention, and not for limiting it. Furthermore, in the drawings, structures that are similar or identical are indicated by the same reference numerals.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] This invention provides a window air conditioner that solves at least one of the following problems: cold air recirculation, short air delivery distance, inaccurate temperature sensing, high noise, and obstruction of lighting. By setting the indoor air outlet and indoor return air outlet on different planes of the indoor casing and keeping the rotation tangential direction of the centrifugal fan consistent with the direction of the indoor air outlet, cold air recirculation is avoided, the air delivery distance is increased, and the temperature sensing accuracy is improved.

[0040] To address at least one of the aforementioned problems—cold air recirculation, short air delivery distance, inaccurate temperature sensing, high noise, and impaired lighting—the present invention provides the following technical solution:

[0041] The specific solution involves vertically arranging the indoor air outlet and indoor return air inlet. The indoor air outlet and indoor heat exchanger are located on the left side of the unit, while the indoor air outlet is located on the front. This arrangement ensures that the indoor air supply and return air are not on the same side, preventing the cool air blown out from the unit from being directly drawn in by the return air inlet, thus avoiding cold air recirculation. More of the cool air blown out is utilized by the room, resulting in better cooling performance. Furthermore, because cold air recirculation is avoided, the indoor temperature sensor is more accurate. Fixed-frequency air conditioners can avoid frequent on / off cycles caused by inaccurate temperature sensing, while variable-frequency air conditioners can avoid frequency reductions and reduced cooling performance due to inaccurate temperature sensing.

[0042] The centrifugal fan blades are placed in the air duct on the indoor side of the unit, behind the indoor heat exchanger, and fixed to the fan blade motor. The indoor return air is drawn in by the centrifugal fan blades and exchanges heat with the indoor heat exchanger. After the air is cooled, it is thrown out by the centrifugal fan blades. The direction of the cold air blown out of the room is the same as the rotation direction of the centrifugal fan blades, resulting in lower air resistance and smoother airflow. At the same fan speed, the air delivery distance is longer, so that people can feel the coolness brought by the air conditioner even at a distance or in a corner of the room.

[0043] The air conditioner casing is designed so that the indoor and outdoor casings are perpendicular, and the whole unit is L-shaped. During installation, the window air conditioner is placed against one side of the wall, and the outdoor compressor is located behind the wall. The wall isolates the direct transmission of compressor noise, reducing the noise caused by the compressor. Installing on one side can increase the exposed lighting area of ​​the window and increase the room's illumination.

[0044] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0045] Reference Figures 3-15 , Figure 3 This is a schematic diagram of a window air conditioner provided in an embodiment of the present invention. The embodiment of the present invention provides a window air conditioner, including: an air conditioner housing 1 and a centrifugal fan blade 2; the air conditioner housing 1 includes an indoor side housing 11a, on which an indoor air outlet 131 and an indoor return air outlet 1121 are provided, the indoor air outlet 131 and the indoor return air outlet 1121 are not on the same plane; the centrifugal fan blade 2 is disposed in the indoor side housing 11a, the axial direction of the centrifugal fan blade 2 is towards the indoor return air outlet 1121, and the circumferential surface of the centrifugal fan blade 2 is towards the indoor air outlet 131.

[0046] Reference Figure 3 and Figure 4Specifically, the air conditioner casing includes an indoor casing 11a and an outdoor casing 11b. When the window air conditioner is installed in the window 9 of the wall 8, the indoor casing 11a is located on the indoor side, and the outdoor casing 11b is located on the outdoor side. The indoor casing 11a, located on the indoor side, is generally rectangular in shape and has six sides: front, back, left side, right side, top, and bottom. The indoor air outlet 131 and the indoor air return vent 1121 are respectively located on two of the above six planes. For example, the indoor air outlet 131 may be located on the front, and the indoor return air outlet 1121 on the left side; the indoor air outlet 131 may be located on the front, and the indoor return air outlet 1121 on the right side; the indoor air outlet 131 may be located on the front, and the indoor return air outlet 1121 on the top; or the indoor return air outlet 1121 may be located on the front, and the indoor return air outlet 1121 on the bottom. Of course, other combinations are also possible, as long as the indoor air outlet 131 and the indoor return air outlet 1121 are not on the same plane; this is not a limitation here. The centrifugal fan 2 is vertically installed in the indoor side housing 11a, with its axis facing the indoor return air outlet 1121. That is, the end of the side of the centrifugal fan 2 faces the indoor return air outlet 1121, so that air entering from the indoor return air outlet 1121 is drawn into the interior of the centrifugal fan 2. As the centrifugal fan blade 2 rotates, the airflow will blow out along the tangential direction of the rotation of the centrifugal fan blade 2. Since the circumferential surface of the centrifugal fan blade 2 faces the indoor air outlet 131, the tangential direction of the rotation of the centrifugal fan blade 2 can point to the indoor air outlet 131, so that the airflow can blow directly towards the indoor air outlet 131 without the airflow needing to turn, thus achieving direct airflow.

[0047] The window air conditioner of this embodiment effectively reduces the mutual interference between the return air and the outlet air, avoids cold air recirculation, improves the accuracy of the indoor temperature sensing bulb, and the rotation tangent direction of the centrifugal fan blade 2 is consistent with the outlet air direction of the indoor air outlet 131, resulting in low air resistance, smooth airflow, and long air delivery distance.

[0048] Reference Figure 5 In one embodiment, the indoor air outlet 131 is located on the front of the indoor housing 11a, and the indoor return air outlet 1121 is located on the side of the indoor housing 11a. Specifically, the indoor air outlet 131 is located on the front, and the indoor return air outlet 1121 is located on the side, which can be the left or right side, so that the indoor air outlet 131 and the indoor return air outlet 1121 are arranged perpendicularly, with side return air and front air outlet air, and the two do not interfere with each other. With this arrangement, the indoor air outlet and return air are not on the same side, and the cold air blown out of the room will not be directly sucked in by the return air outlet, avoiding cold air backflow. More of the cold air blown out of the room is utilized by the room, resulting in better cooling effect.

[0049] Continue to refer to Figure 5In this embodiment, the window air conditioner further includes an indoor heat exchanger 4, which is located between the side of the indoor housing 11a and the centrifugal fan 2. Specifically, the indoor heat exchanger 4 is an evaporator, which is placed near the side of the indoor housing 11a, and the centrifugal fan 2 is located on the side of the evaporator away from the indoor housing 11a, that is, the evaporator is located in the middle between the centrifugal fan 2 and the side. Thus, the airflow enters from the indoor return air inlet 1121 on the side of the indoor housing 11a, first exchanges heat with the evaporator to obtain cold air, and then is drawn in by the centrifugal fan 2 and blown out from the indoor air outlet 131 on the front.

[0050] Furthermore, the fan motor 6 of the centrifugal fan 2 is located on the side of the centrifugal fan 2 furthest from the evaporator, meaning that the fan motor 6 and the evaporator are located on opposite sides of the centrifugal fan 2. Keeping the fan motor 6 away from the evaporator prevents its temperature rise from affecting the cooling effect.

[0051] Continue to refer to Figure 5 In this embodiment, the indoor heat exchanger 4 is placed parallel to the side of the indoor shell 11a. Specifically, since the evaporator has a certain length, it occupies a large space in the indoor shell 11a. Existing evaporators are usually placed laterally in the indoor shell 11a, resulting in a large volume of the indoor shell 11a and a small light-receiving area. In this embodiment, the evaporator is placed longitudinally, along the side of the indoor shell 11a, with its length parallel to the side of the indoor shell 11a. This greatly reduces the width of the indoor shell 11a, allowing for a larger light-receiving area exposed by the window.

[0052] Continue to refer to Figure 3 In one embodiment, the air conditioner housing 1 further includes an outdoor housing 11b, which is connected to the back of the indoor housing 11a. The outdoor housing 11b extends from the back of the indoor housing 11a in a direction perpendicular to the indoor housing 11a. Specifically, the indoor housing 11a and the outdoor housing 11b are connected, and the outdoor housing 11b is located on the back of the indoor housing 11a, perpendicular to the indoor housing 11a. It should be noted that, viewed from above, the outdoor housing 11b extends from the back of the indoor housing 11a in a direction perpendicular to the indoor housing 11a, that is, the outdoor housing 11b extends to the left or right from the back of the indoor housing, thus forming an L-shaped structure. In this way, when the unit is installed, the window air conditioner is placed against one side of the window 9 of the wall 8, so that part of the outdoor housing 11b is located behind the wall 8. One-sided installation can increase the exposed lighting area of ​​the window and increase the room's illumination.

[0053] Continue to refer to Figure 3In this embodiment, the window air conditioner further includes a compressor 5. The outdoor housing 11b includes a blocking area M1. The area of ​​the outdoor housing 11b that is not directly opposite the back of the indoor housing 11a is the blocking area M1, and the compressor 5 is disposed in the blocking area M1. Specifically, the area where the backs of the outdoor housing 11b and the indoor housing 11a are directly opposite is the non-blocking area M2, which faces the window 9. The area where the backs of the outdoor housing 11b and the indoor housing 11a are not directly opposite is the blocking area M1, which is the area behind the wall 8, and the blocking area M1 faces the wall 8. Installing the compressor 5 in the blocking area M1 solves the problem of unobstructed noise from the outdoor compressor 5 of traditional side-discharge window air conditioners being directly transmitted into the room, resulting in poor indoor noise experience. By blocking the direct transmission of noise from the compressor 5, the largest noise source, to the indoor side through the wall 8, indoor noise is reduced, and the experience is more comfortable.

[0054] Reference Figure 6 In one embodiment, the air conditioner housing 1 further includes a base 12. The indoor housing 11a and the outdoor housing 11b are integrally formed to form a cover 11, which is mounted on the base 12. Specifically, the indoor housing 11a and the outdoor housing 11b are integrally formed, forming a single cover 11. Various functional components of the air conditioner are mounted on the base 12. For example, the outdoor heat exchanger, indoor heat exchanger 4, outdoor fan 73, and centrifugal fan are mounted on the base 12. A duct housing 7 can be provided on the base 12 to enclose the centrifugal fan, making the airflow more concentrated. The cover 11, installed vertically from top to bottom, protects the internal components of the air conditioner, resulting in a simple structure and convenient installation.

[0055] Reference Figures 7-9In this embodiment, the enclosure 11 includes a continuous top wall 111, a continuous side wall 112, an indoor side wall 113, an outdoor side wall 114, and an outdoor front wall 115. The continuous side wall 112 is vertically connected to one side of the continuous top wall 111. The indoor side wall 113 and the outdoor side wall 114 are vertically connected to the other side of the continuous side wall 112 opposite to it. The distance between the outdoor side wall 114 and the continuous side wall 112 is greater than the distance between the indoor side wall 113 and the outdoor side wall 114. The distance between the side wall and the connected side wall 112, the outdoor front wall 115 is perpendicularly connected to the connected top wall 111 and connects the indoor side wall 113 to the outdoor side wall 114; the connected top wall 111, the connected side wall 112, and the indoor side wall 113 together form the indoor shell 11a, and the connected top wall 111, the connected side wall 112, the outdoor front wall 115, and the outdoor side wall 114 together form the outdoor shell 11b. Specifically, the shell 11 is L-shaped when viewed from above, that is, the connected top wall 111 is L-shaped, the connected side walls 112, the indoor side wall 113, the outdoor side wall 114, and the outdoor front wall 115 are all perpendicularly connected to the connected top wall 111, and the indoor shell 11a and the outdoor shell 11b share a top wall. The integrated side wall 112 and the indoor side wall 113 are respectively the left or right side of the indoor shell 11a. The integrated side wall 112 and the outdoor side wall 114 are respectively the left or right side of the outdoor shell 11b. The indoor shell 11a and the outdoor shell 11b share a side wall. Since the width of the outdoor shell 11b is greater than that of the indoor shell 11a, the outdoor side wall 114 and the indoor side wall 113 are also connected by the outdoor front wall 115, which is perpendicular to both the indoor side wall and the outdoor side wall 114. The interiors of the indoor shell 11a and the outdoor shell 11b are interconnected and house the air conditioning components. During installation, the indoor side wall 113 is flush against the side of the window 9 of the wall 8, and the outdoor front wall 115 is flush against the wall 8.

[0056] Reference Figure 8 and Figure 9In addition, an outdoor return air vent 1111 is provided on the top wall 111, and an outdoor air outlet 1122 is provided on the outdoor side of the side wall 112. An outdoor fan 73 is also provided in the outdoor side shell 11b. Outdoor air enters the outdoor side shell 11b through the outdoor return air vent 1111 on the top wall 111, and under the action of the outdoor fan 73, the airflow is blown out through the outdoor air outlet 1122 on the side wall 112. An indoor return air vent 1121 is provided on the indoor side of the side wall 112. Grilles are provided on the outdoor return air vent 1111, the outdoor air outlet 1122, and the indoor return air vent 1121. The grilles of the indoor return air vent 1121 are arranged on the top of the shell 11, avoiding the need for a separate return air panel, simplifying the structure and reducing costs.

[0057] Reference Figure 10 and Figure 11 In this embodiment, the air conditioner housing 1 further includes an air outlet panel 13, which is installed on the front side of the integrated top wall 111, the integrated side wall 112, and the indoor side wall 113. An indoor air outlet 131 is formed on the air outlet panel 13, and an air outlet grille is provided on the indoor air outlet 131. Specifically, the air outlet panel 13 is installed on the front of the housing 11, which is a through-type structure enclosed by the integrated top wall 111, the integrated side wall 112, and the indoor side wall 113. The air outlet panel 13 covers the front of the housing. The indoor air outlet 131 is located on the air outlet panel 13, and similarly, a grille is provided on the indoor air outlet 131.

[0058] Reference Figures 12-15 This invention also provides an installation method for a window air conditioner, wherein the window air conditioner is the same as described in the above embodiments, which has been described in detail in the above embodiments and will not be repeated here for the sake of brevity. The installation method includes:

[0059] The vertical connection between the indoor housing 11a and the outdoor housing 11b is installed near the left or right side of the window 9 of the wall 8 so that the outdoor housing 11b is located on the back of the wall 8.

[0060] Specifically, such as Figure 14 and Figure 15 When installing the entire unit, the window air conditioner is placed flush against the right side of the wall 8 at window 9. The outdoor compressor 5 is hidden behind the wall 8 and blocked by the wall 8, reducing the noise caused by the compressor 5. Installing it on one side allows for a larger exposed area of ​​the window, increasing the room's lighting. Of course, it is understandable that... Figure 13 and Figure 14 Alternatively, the entire unit structure can be arranged in the opposite direction, with the indoor air intake on the right side of the unit. During installation, the air conditioner is placed close to the left wall 8 at window 9, while the outdoor compressor 5 is still hidden behind the wall 8 and blocked by the wall 8.

[0061] In this embodiment, the indoor air supply and return air are arranged perpendicularly, and the indoor return air and air supply are not on the same side, thus avoiding cold air recirculation. The air supply direction is along the tangent of the rotation of the centrifugal fan blade 2, resulting in smooth air supply, low air resistance, and a longer air delivery distance. Because the casing structure is different from that of traditional window air conditioners, the outdoor compressor 5 can be hidden behind the wall 8 during installation, and the wall 8 can block the direct transmission of noise from the compressor 5, the largest noise source, to the indoor side. At the same time, the change in installation method can effectively increase the indoor room's lighting area.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
