Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0047] Currently, installing a fresh air component in a window air conditioner requires significant structural modifications, resulting in substantial changes to the air conditioner. In this invention, the fresh air module is directly installed on the front panel of the window air conditioner. Only corresponding fresh air and exhaust air channels need to be opened on the ductwork of the window air conditioner to achieve bidirectional fresh air exchange. This allows for the conversion of a window air conditioner to a fresh air system with minimal modifications, improving the versatility of the fresh air component.

[0048] The following is in conjunction with the appendix Figures 1-9 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0049] Example 1

[0050] like Figures 1-9 As shown, this embodiment proposes a window air conditioner, including:

[0051] The air duct assembly includes a front partition 1, which includes a first panel and a second panel facing each other, the first panel facing the outdoor environment and the second panel facing the indoor environment.

[0052] Fresh air module 2 is located on the first plate of the front partition 1. The surface of the fresh air module 2 is provided with a fresh air inlet 21 and a fresh air outlet 22, and a fresh air flow path is formed inside that is connected to the fresh air inlet 21 and the fresh air outlet 22. The surface of the fresh air module 2 is also provided with an exhaust gas inlet 23 and an exhaust gas outlet 24, and an exhaust gas flow path is formed inside that is connected to the exhaust gas inlet 23 and the exhaust gas outlet 24.

[0053] The air duct assembly is provided with a fresh air duct 11 and an exhaust gas duct 12. One end of the fresh air duct 11 is connected to the fresh air exhaust port 22 and the other end is connected to the indoor environment. One end of the exhaust gas duct 12 is connected to the indoor environment and the other end is connected to the exhaust gas inlet 23.

[0054] In this embodiment of the invention, the fresh air module 2 is directly installed on the front partition 1 of the window air conditioner, and the fresh air channel 11 and exhaust gas channel 12 are opened at the corresponding positions on the air duct assembly of the window air conditioner to realize the bidirectional fresh air exchange function of the window air conditioner. The fresh air transformation of the window air conditioner is realized with minimal modifications, and the versatility of the fresh air component is improved.

[0055] Specifically, when the window air conditioner introduces fresh air, the outside fresh air enters the fresh air module 2 through the fresh air inlet 21 and is discharged into the fresh air duct 12 of the air duct assembly through the fresh air outlet 22. The outside fresh air is discharged into the indoor environment through the fresh air duct 11. At the same time, the exhaust gas in the indoor environment enters the fresh air module 2 through the exhaust gas duct 12 of the air duct assembly and the exhaust gas inlet 23 connected to the exhaust gas duct 12, and is discharged into the outdoor environment through the exhaust gas outlet 24 of the fresh air module 2.

[0056] Specifically, such as Figure 3 and Figure 4 As shown, the fresh air module 2 has a first mounting surface 25, and the fresh air module 2 is mounted on the front partition 1 through the first mounting surface 25;

[0057] Both the fresh air exhaust port 22 and the exhaust gas inlet 23 are located on the first mounting surface 25. Preferably, the fresh air module 2 is provided with two mounting ears, and the front partition 1 is provided with two module mounting holes. The fresh air module 2 is mounted on the two module mounting holes on the front partition 1 through the two mounting ears.

[0058] In this embodiment of the invention, by setting the fresh air exhaust port 22 and the exhaust gas inlet 23 on the same surface, and setting the fresh air channel 11 and the exhaust gas channel 12 connecting the fresh air exhaust port 22 and the exhaust gas inlet 23 on the air duct assembly, the fresh air exhaust port 22 and the exhaust gas inlet 23 can be directly connected to the indoor environment without the need for connecting pipes.

[0059] In any of the above embodiments, such as Figure 3 and Figure 4 As shown, the fresh air module 2 also has a second mounting surface 26 and a third mounting surface 27. The fresh air inlet 21 is opened on the second mounting surface 26, and the exhaust gas outlet 24 is opened on the third mounting surface 27.

[0060] The second mounting surface 26 and the third mounting surface 27 are arranged opposite to each other.

[0061] In this embodiment of the invention, by designing the fresh air inlet 21 and the exhaust outlet 24 on two opposing mounting surfaces of the fresh air module 2, the fresh air and exhaust gas will not cross each other.

[0062] In any of the above embodiments, such as Figures 5-8 As shown, the air duct assembly also includes an air duct volute 3, which is disposed on the second plate side of the front partition 1.

[0063] The fresh air duct 11 includes a first fresh air duct section 111 disposed on the front partition 1 and a second fresh air duct section 112 disposed on the air duct volute 3. The first fresh air duct section 111 and the second fresh air duct section 112 correspond to and are connected to each other.

[0064] The exhaust gas passage 12 includes a first exhaust gas passage section 121 disposed on the front partition 1 and a second exhaust gas passage section 122 formed by the gap between the front partition 1 and the air duct volute 3. The first exhaust gas passage section 121 and the second exhaust gas passage section 122 correspond to and are connected to each other.

[0065] In this embodiment of the invention, the fresh air duct 11 and the exhaust gas duct 12 are both set on the original air duct assembly of the window air conditioner without adding any additional airflow ducts. Without changing the original layout of the window air conditioner, the original components of the window air conditioner are fully utilized to achieve the effects of fresh air intake and exhaust gas exhaust.

[0066] In any of the above embodiments, such as Figure 2 and Figure 8 As shown, the air conditioner has an indoor air vent 4 that communicates with the indoor environment. The indoor air vent 3 is provided with a grille. The air conditioner also includes a heat exchanger 5, which is located at the indoor air vent 4 and covers part of the indoor air vent 4.

[0067] The end of the fresh air duct 11 that connects to the indoor environment is spaced apart from or abuts against the heat exchanger 5.

[0068] Preferably, the heat exchanger 5 mentioned above is an evaporator.

[0069] Specifically, such as Figure 8 As shown, when the fresh air duct 11 and the heat exchanger 5 are spaced apart, part of the fresh air introduced from the outside can be cooled by the heat exchanger 5 and then enter the indoor environment. Since part of the indoor air vent 4 is not blocked by the heat exchanger 5, the other part of the fresh air introduced from the outside can enter the indoor environment directly without passing through the heat exchanger 5 under the centrifugal action of the centrifugal fan blade 6 in the air duct.

[0070] Of course, in some embodiments not shown, when the exhaust end of the fresh air duct 11 directly abuts against the heat exchanger 5, all the fresh air introduced from the outside can be cooled by the heat exchanger 5 before entering the indoor environment.

[0071] It is worth noting that when the exhaust end of the fresh air duct 11 directly abuts against the heat exchanger 5, the velocity and volume of the fresh air entering the indoor side will be affected to some extent. Therefore, relatively speaking, preferably, in this embodiment, the end of the fresh air duct 11 that connects to the indoor environment (i.e., the exhaust end) is set at a certain distance from the heat exchanger 5.

[0072] In any of the above embodiments, such as Figure 2 and Figure 8 As shown, the air duct assembly also includes an air duct centrifugal fan 6 disposed between the heat exchanger 5 and the air duct volute 3;

[0073] The duct volute 3 has a recessed fan blade mounting cavity 31, and the duct centrifugal fan blade 6 is disposed in the fan blade mounting cavity 31.

[0074] Combination Figure 8 As indicated by the direction of the middle arrow (i.e., the direction of fresh air flow) and the above description, when there is a distance between the exhaust end of the fresh air duct 11 and the heat exchanger 5, the centrifugal fan 6 driven by the air duct rotates, allowing a portion of the outdoor fresh air to enter the room through the heat exchanger 5, and allowing another portion of the outdoor fresh air to enter the room without passing through the heat exchanger 5.

[0075] In any of the above embodiments, such as Figure 9 As shown, the fresh air module 2 is equipped with a total heat exchanger 2a inside;

[0076] The total heat exchanger 2a is located on the flow path of the fresh air flow path and the flow path of the exhaust gas flow path. The total heat exchanger 2a is used to exchange heat between the fresh air and the exhaust gas passing through it.

[0077] In this embodiment of the invention, by setting a total heat exchanger 2a in the fresh air module 2, when outdoor fresh air is introduced into the indoor side and indoor exhaust gas is discharged to the outdoor side, the outdoor fresh air and indoor exhaust gas can exchange heat through the total heat exchanger 2a in the fresh air module 2, thereby using the indoor exhaust gas to cool / heat the outdoor fresh air, so that the fresh air introduced into the room is more in line with the indoor temperature and the fresh air introduction effect is better.

[0078] At the same time, combined with the heat exchanger 5 set at the indoor air outlet 4, the fresh air after heat exchange by the total heat exchanger 2a can pass through the heat exchanger again, taking into account both cooling and heating effects, making the fresh air introduced into the room more in line with the indoor ambient temperature, and providing a better user experience.

[0079] In any of the above embodiments, such as Figure 9 As shown, the interior of the fresh air module 2 also includes a fresh air motor 2b, a first partition 2c and a second partition 2d arranged opposite to each other, a fresh air volute 2e, and an exhaust gas volute 2f;

[0080] The fresh air motor 2b is located between the first partition 2c and the second partition 2d. The fresh air motor 2b is a dual-shaft motor. One output shaft of the fresh air motor 2b passes through the first partition 2c and is connected to the fresh air centrifugal fan blade 2g. The other output shaft of the fresh air motor 2b passes through the second partition 2b and is connected to the exhaust gas centrifugal fan blade 2h.

[0081] The fresh air volute 2e has a built-in fresh air centrifugal fan blade 2g, and the exhaust gas volute 2f has a built-in exhaust gas centrifugal fan blade 2h.

[0082] Fresh air module 2 also includes:

[0083] The fresh air cover, fresh air motor 2b, first partition 2c, second partition 2d, fresh air volute 2e, exhaust gas volute 2f and total heat exchanger 2a are disposed in the fresh air cover. The fresh air cover has a fresh air inlet 21, a fresh air outlet 22, an exhaust gas inlet 23 and an exhaust gas outlet 24. The fresh air cover includes a first side fresh air cover 2i and a second side fresh air cover 2j that are opposite to and snapped together, and an upper fresh air cover 2k that covers the first side fresh air cover 2i and the second side fresh air cover 2j.

[0084] A fresh air filter 2l is installed at the fresh air intake 21.

[0085] Specifically, the fresh air inlet 21 and the exhaust outlet 24 are located on opposite walls of the upper fresh air cover 2k, the fresh air exhaust outlet 22 is located on the first side fresh air cover 2i, and the exhaust inlet is located on the second side fresh air cover 2j.

[0086] More specifically, such as Figure 9 As shown, the fresh air motor 2b is surrounded by the first partition 2c and the second partition 2d. The fresh air centrifugal fan blade 2g is installed on the motor shaft on one side of the first partition 2c. The fresh air volute 2e is installed on the side of the fresh air centrifugal fan blade 2g near the first partition 2c. The exhaust gas volute 2f is first installed on one side of the second partition 2d, and then the exhaust gas centrifugal fan blade 2h is installed on the motor shaft on that side.

[0087] The first side fresh air cover 2i and the second side fresh air cover 2j of the fresh air module 2 are fastened together to surround the above-mentioned components. Then, the upper fresh air cover 2k is installed on the upper side. The total heat exchanger 2a is installed on the upper side of the first partition 2c and the second partition 2d and on the lower side of the upper fresh air cover 2k. A fresh air filter 2l is provided inside the fresh air inlet 21 to filter the fresh air introduced from the outside.

[0088] It should be noted that the centrifugal fan blades 6 in the duct can be placed horizontally. For integrated air conditioners with a shorter outdoor side, such as through-wall units, they can also be set parallel to the front partition 1. The direction of the centrifugal fan blades 6 and the duct volute 3 can be adjusted arbitrarily according to the actual situation. At the same time, the position of the mounting ears of the fresh air module 2 can be adjusted arbitrarily.

[0089] It should also be noted that the air inlet and outlet surfaces of the total heat exchanger 2a are not horizontal or vertical, and the installation angle can be adjusted arbitrarily according to the actual situation. Furthermore, the position of the total heat exchanger 2a can be on the upper, lower, outer, inner, left, and right sides of the two fan blades {fresh air centrifugal fan blade 2g and exhaust gas centrifugal fan blade 2h}.

[0090] It should also be noted that the fresh air module 2 can be installed in any part of the front partition 1 near the outdoor side where there is space.

[0091] Example 2

[0092] The difference between this embodiment and embodiment 1 is that the fresh air duct in this embodiment includes a first fresh air duct provided on the front partition and a second fresh air duct section provided on the air duct volute. The first fresh air duct section and the second fresh air duct section correspond to and are connected to each other.

[0093] The exhaust gas passage includes a first exhaust gas passage disposed on the front partition and a second exhaust gas passage disposed on the duct volute. The first exhaust gas passage and the second exhaust gas passage correspond to and are connected to each other.

[0094] Example 3

[0095] The difference between this embodiment and Embodiments 1 and 2 is that the air duct assembly in this embodiment includes an air duct volute 3, which is disposed on the second plate side of the front partition 1.

[0096] The fresh air duct includes a first fresh air duct located on the front partition and a second fresh air duct formed by the gap between the front partition and the air duct volute. The first fresh air duct and the second fresh air duct correspond to and are connected to each other.

[0097] The exhaust gas passage includes a first exhaust gas passage disposed on the front partition and a second exhaust gas passage formed by the gap between the front partition and the duct volute. The first exhaust gas passage and the second exhaust gas passage correspond to and are connected to each other.

[0098] It is worth noting that although the specific formation methods of the fresh air duct 11 and the exhaust gas duct 12 are different in Embodiments 1, 2 and 3, they can all achieve the effects of fresh air intake and exhaust gas exhaust by making full use of the original components of the window air conditioner without changing the original layout of the window air conditioner.
