A heat exchanger 22 and a window air conditioner 100 according to embodiments of the present application are described below with reference to the accompanying drawings. The heat exchanger 22 according to the embodiments of the present application is applicable to an apparatus requiring heat exchange such as an air conditioner 1000, but the type of the air conditioner 1000 is not limited. For example, the air conditioner 1000 may be the window air conditioner 100. For example, in specific examples shown in

Therefore, the heat exchanger 22 according to the embodiments of the present application adopts the special-shape cutting and then is bent directly (for example, being bent directly by hands), and the manufacturing is very simple and convenient, thus effectively improving the manufacturing efficiency and reducing the cost. Moreover, since the first fin member 221a and the second fin member 221b are an integral cut and bent structure, so it is unnecessary for splicing, so that the filling of a sponge and a snap ring at a spliced place is avoided, so as to avoid the influence of the sponge and the snap spring on the heat exchange, thus improving the heat exchange, and enhancing the uniformity of air supply, and facilitating the smooth discharge of condensate water.

During processing, a plurality of integral fins with the same structure can be stacked together to form the fin set 221, and then the fin set 221 is cut by using the special-shape cutting to obtain the first notch 2211 and the second notch 2213. But the first connection member 2212 and the second connection member 2214 can be obtained without completely cutting off the fin 221, and then the fin set 221 can be bent respectively from the cutting lines, namely the first notch 2211 and the second notch 2213, so that the fin set 221 is divided into the first fin member 221a and the second fin member 221b on two sides of the first notch 2211, as well as the second fin member 221b and the third fin member 221c on two sides of the second notch 2213. The second fin member 221b is located between the first notch 2211 and the second notch 2213. The first fin member 221a and the second fin member 221b are connected via the first connection member 2212 which is not cut off, and the first fin set 221 and the second fin set 221 have the non-zero included angle therebetween due to bending. The second fin member 221b and the third fin member 221c are connected via the second connection member 2214 which is not cut off, and the second fin set 221 and the third fin set 221 have the non-zero included angle therebetween due to bending.
In some embodiments of the present application, after the fin set 221 is molded by bending, there is a gap between the second fin member 221b and the third fin member 221c at the second notch 2213. That is, the second fin member 221b and the third fin member 221c having the non-zero included angle therebetween have a second gap S2 at a position (including positions of two second sub notches A2 described later) of the second notch 2213. It is shown that during the whole bending process, the second fin member 221b and the third fin member 221c do not interfere with each other, and there is not a problem that the fins will interfere with each other and collapse at the second notch 2213. For example, the above requirement can be met by using the special-shape cutting. Therefore, it is more conducive to improving the heat exchange, enhancing the uniformity of air supply and facilitating the smooth discharge of condensate water.
In some embodiments of the present application, the second notch 2213 may include two second sub notches A2, and the two second sub notches A2 are respectively arranged at the air input side R1 and the air output side R2 of the second connecting unit 2214. Thus, the second gap S2 of the second fin member 221b and the third fin member 221c at the second notch 2213 can be reduced, thus further improving the heat exchange, enhancing the uniformity of air supply and facilitating the smooth discharge of condensate water.

In addition, it is necessary to note that the side plate 223 may be an integral member or a spliced member. When the side plate 223 is the integral member, the side plate 223 may be formed by cutting through a cutting process, and the side plate 223 may also be processed by a process similar to the fin set 221, in which the side plate 223 is cut by using the special-shape cutting first and then is molded by bending. Moreover, two side plates 223 may be fixed at two sides of the fin set 221 respectively, and then the side plate 223 and the fin set 221 are cut simultaneously by using the special-shape cutting and bent simultaneously, thus simply and effectively ensuring that the extension line L4 of the side plate 223 coincides or is parallel to the extension line L5 of the fin set 221. Of course, the present application is not limited to this. The side plate 223 and the fin set 221 may also be processed respectively and then assembled. In addition, when the side plate 223 is the spliced member, which indicates that the side plate 223 includes a plurality of separately molded plate pieces, the plurality of plate pieces is arranged at corresponding included angles according to the extension line of the fin set 221, and then is connected with each other, or, the plurality of plate pieces may be directly mounted at the fin set 221 respectively.

Therefore, the cost of the indoor filter screen 25 can be reduced and the filtration reliability of the indoor filter screen 25 can be improved. In addition, the indoor filter screen 25 is arranged parallel or substantially parallel to the fin set 221, so that the air input from the indoor filter screen 25 to the heat exchanger 22 can be more uniform and the vortex can be reduced, which is conducive to reducing the air input noise. In addition, when the fin set 221 also includes the third fin member 221c, the indoor filter screen 25 may also include a third sub screen, and the third sub screen is parallel to the third fin member 221c or has an included angle within 10° with the third fin member 221c.
In some embodiments of the present application, a distance between the first sub screen 251 and the first fin member 221a is d1, a distance between the second sub screen 252 and the second fin member 221b is d2, d1 and d2 satisfy: 0.9≤d1/d2≤1.2. For example, d1/d2 is 0.91, 0.95, 0.99, 1, 1.11 and other parameters. Therefore, it is beneficial to further reducing the generation of the vortex and reducing the noise.

A plane where the air outlet 2702 is located is an air output surface, and the air output surface extends obliquely rearwards from bottom to top. The volute assembly 27 is used in the window air conditioner 100, which can shorten a length of the air channel 2701, thus reducing a length of a flow path of an airflow in the air channel 2701, and reducing the flow loss of the airflow and increasing the air supply distance. Moreover, the space occupied by the volute assembly 27 in a height direction can be reduced. In addition, the air outlet 2702 can supply the air in an inclined upward direction, so as to avoid the cold air from sinking and directly blowing to people. The inclined air output surface can also increase an air output area, enhance the air output effect and improve the working performance of the air conditioner 1000.
In the window air conditioner 100 according to the embodiments of the present application, the air output surface of the air outlet 2702 is arranged at extend obliquely rearwards from bottom to top, so as to shorten a length of the air channel 2701, reduce the flow loss of the airflow, increase the air supply distance, and allow the air outlet 2702 to supply the air in the inclined upward direction, thus avoiding the cold air from directly blowing to people, reducing the space occupied by the volute assembly 27 in height and improving the air output effect. It is necessary to note that the first volute 271 and the second volute 272 are both separately molded members. Thus, by configuring the volute assembly 27 into the first volute 271 and the second volute 272 molded separately, it is convenient to assemble components in the air channel 2701, for example, the mounting operations of an air guide plate and the indoor fan 21 in the air channel 2701 can be more convenient. Moreover, the processing and manufacturing of the first volute 271 and the second volute 272 can be convenient, and the manufacturing difficulty is reduced.
The expression “the first volute 271 and the second volute 272 are both separately molded members” refers to that the first volute 271 and the second volute 272 are processed separately, and then assembled and fixed. For example, the first volute 271 and the second volute 272 are injection molded members respectively. After being injection molded, the first volute 271 and the second volute 272 are fixed by a plurality of screw fasteners (e.g., by using two screw fasteners). For example, the first volute 271 and the second volute 272 are injection molded members respectively. A hook is integrally formed on the first volute 271, and a snapping hole fitted with the hook is integrally formed in the second volute 272. The fixed connection between the first volute 271 and the second volute 272 is realized by the fit of the hook and the snapping hole. For example, the first volute 271 and the second volute 272 are sheet metal members or castings respectively.
Compared with a volute device in the related art in which a volute tongue strip is connected to a circumferential surface of a volute air channel, the volute assembly 27 of the window air conditioner 100 according to the embodiments of the present application is formed by the first volute 271 and the second volute 272 connected and fitted with each other. The first volute 271 and the second volute 272 are respectively formed into separate components. As shown in

In some embodiments, the volute assembly 27 also includes a motor cage 273. As shown in
In some embodiments, as shown in
In some embodiments, the motor cage 273 may be molded integrally with the first volute 271, and the motor cage 273 is connected to the second volute 272 by the snap and the screw 275. Or, the motor cage 273 is molded integrally with the second volute 272, and the motor cage 273 is connected to the first volute 271 by the snap and the screw 275. In this way, the molding is convenient, the structure is more stable and also the assembling efficiency is improved.
In some embodiments, as shown in
In some embodiments, as shown in
It can be understood that, since the left and right ends of the first extension plate 2712 of the first volute 271 extend beyond the volute tongue body 2711, the left and right ends of the second extension plate 2722 of the second volute 272 extend beyond the volute body 2721, and the motor cage 273 is arranged at the left end of the volute assembly 27 and is located below the first extension plate 2712 and the second extension plate 2722, when the first cage body 2731 and the second cage body 2732 are mounted, or when the motor cage 273 and the first volute 271 and/or the second volute 272 are mounted, it will cause great inconvenience to operation if the screw connection in the related art is still used, i.e., the hand or tool cannot be stretched thereinto for operation due to a space limitation. In the embodiments of the present application, the upper end of the first cage body 2731 and the upper end of the second cage body 2732 is connected by the second snap 2733. When the first cage body 2731 and the second cage body 2732 are connected, the second snap 2733 may pass through the fitting hole and be engaged in the fitting hole after a connection surface of the first cage body 2731 and a connection surface of the second cage body 2732 abut with each other. The assembling is very convenient, the number of screws 275 is reduced and also the operation efficiency is improved.

Therefore, by rotatably arranging the air guide plate 26 at the air outlet 2702 of the air channel 2701, the air output area of the air outlet can be adjusted easily when the air guide plate 26 rotates. It is conducive to improving the air supply range of the window air conditioner 100 when the air guide plate 26 opens the air outlet 2702 of air channel 2701 to a large extent. It is conducive to increasing the air output pressure when the air guide plate 26 opens the air outlet to a small extent, so as to realize a long-distance air supply and provide a good air guide effect. In addition, during the mounting of the window air conditioner 100, the air guide plate 26 and the volute assembly 27 can be assembled, so that the air channel assembly 2A can be then mounted as a whole module in an indoor casing 20 of the window air conditioner 100, which is conducive to further improving the assembling efficiency of the window air conditioner 100.
In some embodiments of the present application, as shown in
For example, as shown in
In some embodiments of the present application, as shown in
In some embodiments of the present application, an accommodating groove is formed in the volute assembly 27 (for example, the first volute 271 described above), and the drive motor 281 is mounted to the accommodating groove. For example, the accommodating groove recessed towards an interior of the air channel 2701 is formed in an outer surface of the volute assembly 27, and the drive motor 281 is mounted in the accommodating groove. A motor shaft of the drive motor 281 penetrates through a bottom wall (an inner wall opposite to an opening) of the accommodating groove and into the air channel 2701 to be connected to the air guide plate 26 located at the air outlet 2702 of the air channel 2701, and then drives the air guide plate 26 to rotate.
In some embodiments of the present application, a vent hole communicated with the air channel 2701 is formed in the bottom wall of the accommodating groove, so that a part of the airflow can flow to the drive motor 281 through the vent hole when the airflow flows through the air channel 2701, thus dissipating heat in the drive motor 281 by the airflow, so as to improve the working reliability of the drive motor 281.
In some embodiments of the present application, a plurality of vent holes are provided, the plurality of vent holes are spaced apart from each other along a circumferential direction of the drive motor 281, and each vent hole extends into a strip shape. Therefore, the heat dissipation effect of the drive motor 281 can be further improved.
In some embodiments of the present application, the air channel assembly 2A also includes a transmission member 282, the transmission member 282 is connected between the motor shaft of the drive motor 281 and the air guide plate 26, and the drive motor 281 drives the transmission member 282 to rotate, for driving the air guide member to rotate. For example, the transmission member 282 is a chain, and the chain surrounds the motor shaft of the drive motor 281 and a transmission shaft at an end of the air guide plate 26 and is fitted with the motor shaft and the transmission shaft. Therefore, when the motor shaft of the drive motor 281 rotates, the rotation of the motor shaft drives the chain to rotate synchronously, and the rotation of the chain drives the transmission shaft to rotate synchronously, thus realizing the rotation of the air guide plate 26 driven by the drive motor 281.
In some embodiments of the present application, referring to
In the related art, the drive motor and the air guide plate are generally located at two sides of the transmission member. In order to realize the mounting of the drive motor, a fixing member for fixing the drive motor shall be additionally arranged at a mounting member (such as the volute assembly described above) where the air guide plate is located, which leads to the need for additional fixing members, so that a width of the whole volute assembly (the width refers to a dimension of the volute assembly along an axial direction of the motor) is large, and a material cost is high. However, in this embodiment, the drive motor 281 is directly fixed to the volute assembly 27, thus eliminating the additional fixing member, so that an overall width of the volute assembly 27 is reduced and the manufacturing cost is saved.
Therefore, by locating the drive motor 281 and the air guide plate 26 on the same side of the transmission member 282, it is conducive to reducing a volume of the volute assembly 27, saving the space and reducing the material cost.
In some embodiments of the present application, the transmission member 282 includes a first gear 2821 and a second gear 2822, the first gear 2821 is meshed with the second gear 2822, the first gear 2821 is connected to the motor shaft, and the second gear 2822 is connected to the air guide plate 26.
For example, as shown in
In some embodiments of the present application, as shown in
In some embodiments of the present application, there is one air guide plate 26, and the one air guide plate 26 is arranged at the air outlet 2702 of the air channel 2701. The air output region can be opened or closed by the rotation of the one air guide plate 26, and the airflow guide effect can also be realized. In some other embodiments, a plurality of air guide plates 26 may also be provided, and the plurality of air guide plates 26 are spaced apart and linked. In the window air conditioner 100 according to the embodiments of the present application, by the arrangement of the above air channel assembly 2A, the air output area of the air outlet 2702 can be adjusted easily when the air guide plate 26 rotates. It is conducive to improving the air supply range of the window air conditioner 100 when the air guide plate 26 opens the air outlet 2702 of the air channel 2701 to a large extent. It is conducive to increasing the air outlet pressure when the air guide plate 26 opens the air outlet to a small extent, so as to realize a long-distance air supply and provide a good air guide effect. In addition, during the mounting of the window air conditioner 100, the air guide plate 26 and the volute assembly 27 may be assembled, so that the air channel assembly 2A may be then mounted as a whole module in an air conditioner housing 100A of the window air conditioner 100, which is conducive to further improving the assembling efficiency of the window air conditioner 100.
In some embodiments of the present application, as shown in
In some embodiments of the present application, an outer end face of the decorative strip 70 is flush with an outer end face of the air output region. Therefore, it is conducive to further optimizing the appearance of the window air conditioner 100 and improving the visual experience of the user.
In some embodiments of the present application, as shown in
For example, in the specific example shown in
According to some embodiments of the present application, referring to
The window air conditioner 100 is suitable to be supported in a window 2001 of a wall 2000, and a slidable (up and down or left and right) sash 2002 is arranged in the window 2001. At least a part of the sash 2002 is suitable for (downwards or horizontally) extending into the receiving groove 101.
