[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] Reference below Figure 1-Figure 11 An air conditioner according to an embodiment of the present utility model is described.

[0046] Reference Figure 1-Figure 11 According to an embodiment of the utility model, the air conditioner comprises a casing 1, a filter 2 and a heat exchange air supply component 3. An air inlet 11 and an air outlet 19 are formed on the casing 1. The airflow enters the casing 1 through the air inlet 11. In the process of the airflow entering the casing 1 through the air inlet 11, the airflow enters the casing 1 after being filtered by the filter 2, and the airflow entering the casing 1 can exchange heat with the heat exchange air supply component 3. The airflow after heat exchange can be blown out through the air outlet 19 and blown into the room to cool down or heat up the room. The heat exchange air supply component 3 can include a heat exchanger component 31 and a fan component 32. The heat exchanger component 31 can be located between the fan component 32 and the air inlet 11. The fan component 32 drives the airflow to enter the casing 1 from the air inlet 11, and blow it out from the air outlet 19 to the room after heat exchange with the heat exchanger component 31.

[0047] The air inlet 11 may be formed at the rear of the housing 1 , and the air outlet 19 may be formed at the front of the housing 1 . For example, there may be two air outlets 19 spaced apart from each other on the left and right.

[0048] Optionally, the air conditioner can be a split-type air conditioner, which can include an air conditioner indoor unit 100 and an air conditioner outdoor unit. The casing 1 of the air conditioner indoor unit 100 has an air inlet 11 and an air outlet 19, and the filter 2 can be detachably arranged at the air inlet 11 of the air conditioner indoor unit 100.

[0049] For example, the air conditioner can be a split floor-standing air conditioner, and the air conditioner can include an air conditioner indoor unit 100 and an air conditioner outdoor unit, wherein the air conditioner indoor unit 100 is a cabinet unit, and the air conditioner indoor unit 100 includes the above-mentioned housing 1, filter 2 and heat exchange and air supply assembly 3. The housing 1 has a first installation cavity 1a and a second installation cavity 1b arranged up and down, and the second installation cavity 1b can be located at the lower side of the first installation cavity 1a. The heat exchange and air supply assembly 3 is installed in the first installation cavity 1a, and the air inlet 11 and the air outlet 19 are formed on the side wall of the first installation cavity 1a. When the heat exchange and air supply assembly 3 is working, the indoor airflow enters the first installation cavity 1a from the air inlet 11, and after heat exchange with the heat exchange and air supply assembly 3, it is blown out to the room from the air outlet 19. An air treatment module 4 may be provided in the second installation cavity 1b. The air treatment module 4 may have at least one of the functions of purification, humidification, and fresh air. An air inlet and an air outlet may be formed on the side wall of the second installation cavity 1b. Indoor or outdoor air may enter the second installation cavity 1b from the air inlet. The introduced outdoor air or indoor air is processed by the air treatment module 4 in the second installation cavity 1b and then discharged into the room, thereby improving the indoor air quality.

[0050] Reference Figure 2-Figure 4 The air inlet 11 includes a main air inlet 101 and an auxiliary air inlet 102 arranged along a first direction, and a main air inlet grille 103 is provided at the main air inlet 101. The first direction may be the circumference of the housing 1, and the main air inlet 101 and the auxiliary air inlet 102 may be arranged in sequence along the circumference of the housing 1, the main air inlet 101 plays a main air intake role, and the auxiliary air inlet 102 plays an auxiliary air intake role.

[0051] Reference Figure 3 and Figure 6 The filter 2 is detachably mounted at the air inlet 11. The filter 2 can filter dust and other impurities in the air flow entering the air conditioner from the air inlet 11 to improve the air quality. By detachably mounting the filter 2 at the air inlet 11 of the air conditioner, the filter 2 can be easily maintained, disassembled, cleaned or replaced.

[0052] Reference Figure 3 and Figure 6, the filter 2 includes a first filter portion 21 and a second filter portion 22 connected to each other, the first filter portion 21 is located at the main air inlet 101 and the first filter portion 21 is located inside the main air inlet grille 103, and the second filter portion 22 is located at the auxiliary air inlet 102. The first filter portion 21 of the filter 2 refers to the portion of the filter 2 located at the main air inlet 101 and inside the main air inlet grille 103, and most of the air flow passes through the first filter portion 21, and the second filter portion 22 of the filter 2 refers to the portion of the filter 2 located at the auxiliary air inlet 102, and a small part of the air flow passes through the second filter portion 22. In addition, by arranging the first filter portion 21 inside the main air inlet grille 103, the main air inlet grille 103 can protect and support the first filter portion 21, reduce the extrusion or wear of the first filter portion 21 by external force; and the main air inlet grille 103 can improve the structural strength of the portion of the housing 1 located near the main air inlet 101.

[0053] Reference Figure 3 and Figure 6 The filter 2 is suitable for being installed at the air inlet 11 through the auxiliary air inlet 102 or the filter 2 is suitable for being taken out through the auxiliary air inlet 102. The filter 2 can be installed at the air inlet 11 from the auxiliary air inlet 102 or removed through the auxiliary air inlet 102. For example, when installing the filter 2, the filter 2 can be installed to the air inlet 11 from the auxiliary air inlet 102, so that the first filter part 21 of the filter 2 is inserted through the auxiliary air inlet 102 and pushed along the first direction and in the direction close to the main air inlet 101, so that the first filter part 21 of the filter 2 corresponds to the main air inlet 101. After the filter 2 is installed in place, the second filter part 22 of the filter 2 corresponds to the auxiliary air inlet 102, which can facilitate the user to install the filter 2; when the filter 2 needs to be removed, the first filter part 21 of the filter 2 can be pulled from the auxiliary air inlet 102, so that the filter 2 moves along the first direction and in the direction away from the main air inlet 101, and the second filter part 22 of the filter 2 is first pulled out from the auxiliary air inlet 102, and then the first filter part 21 of the filter 2 is pulled out from the auxiliary air inlet 102, and finally the filter 2 is taken out as a whole.

[0054] By setting the main air inlet 101, a large air intake of the air conditioner can be ensured, and at the same time, the auxiliary air inlet 102 is set on one side of the main air inlet 101, which can increase the air intake area, thereby increasing the air intake. The auxiliary air inlet 102 can not only increase the air intake, but also be used as a disassembly and assembly port for the filter 2. By using the disassembly and assembly port for disassembling the filter 2 as the auxiliary air inlet 102, and making the second filter part 22 of the filter 2 opposite to the auxiliary air inlet 102, it is not only possible to install or remove the filter 2 from the auxiliary air inlet 102, but also when the size of the filter 2 is constant, the effective filtering area of ​​the filter 2 can be effectively increased. Since the disassembly and assembly port for disassembling the filter 2 is used as the auxiliary air inlet 102, the air intake area can be increased, thereby increasing the air intake of the air conditioner.

[0055] According to the air conditioner according to the embodiment of the utility model, by setting an auxiliary air inlet 102 and using the auxiliary air inlet 102 as a disassembly and assembly port for disassembling the filter 2, not only can the filter 2 be installed or removed from the auxiliary air inlet 102, but the effective filtering area of ​​the filter 2 can be effectively increased, and the air intake area can be increased, thereby increasing the air intake volume of the air conditioner.

[0056] According to some embodiments of the present invention, referring to Figure 3 and Figure 6 , the extension length of the auxiliary air inlet 102 in the first direction is less than the extension length of the main air inlet 101 in the first direction. The extension length of the main air inlet 101 in the first direction is greater than the extension length of the auxiliary air inlet 102 in the first direction, which can ensure that the main air inlet 101 covers most of the air inlet area and plays a main air inlet role, and the air inlet area covered by the auxiliary air inlet 102 is less than the air inlet area covered by the main air inlet 101, and plays an auxiliary air inlet role.

[0057] Reference Figure 1 , Figure 3 and Figure 6 For example, the first direction may be the circumference of the casing 1, and the main air inlet 101 and the auxiliary air inlet 102 are arranged in sequence along the circumference of the casing 1, and the extension length of the main air inlet 101 along the circumference of the casing 1 is greater than the extension length of the auxiliary air inlet 102. By setting the auxiliary air inlet 102, the air intake volume of the air conditioner can be increased.

[0058] According to some embodiments of the present invention, referring to Figure 3 and Figure 6, the extension length of the auxiliary air inlet 102 in the second direction is not less than the extension length of the main air inlet 101 in the second direction, for example, the extension length of the auxiliary air inlet 102 in the second direction is greater than the extension length of the main air inlet 101 in the second direction, or the extension length of the auxiliary air inlet 102 in the second direction is equal to the extension length of the main air inlet 101 in the second direction, and the second direction is perpendicular to the first direction. In the second direction, by setting the extension length of the auxiliary air inlet 102 to be not less than the extension length of the main air inlet 101, it can be ensured that the user can disassemble and assemble the filter 2 through the auxiliary air inlet 102 in the second direction, thereby facilitating the disassembly and assembly of the filter 2.

[0059] For example, the first direction may be the circumference of the casing 1, and the second direction may be the length direction of the casing 1. The circumference of the casing 1 is perpendicular to the length direction of the casing 1. The main air inlet 101 and the auxiliary air inlet 102 are arranged along the circumference of the casing 1, and the extension length of the main air inlet 101 is greater than the extension length of the auxiliary air inlet 102. This can ensure that the coverage area of ​​the auxiliary air inlet 102 is smaller than the coverage area of ​​the main air inlet 101, thereby increasing the air intake volume of the air conditioner. Furthermore, since the first filter portion 21 of the filter 2 is located at the main air inlet 101, it can be understood that the extension length of the filter 2 along the length direction of the casing 1 is not greater than the extension length of the main air inlet 101 in the length direction of the casing 1. By setting the extension length of the main air inlet 101 to be not greater than the extension length of the auxiliary air inlet 102 in the length direction of the casing 1, it is ensured that the extension length of the auxiliary air inlet 102 in the length direction is not less than the extension length of the filter 2. This can further ensure that the user can disassemble and assemble the filter 2 from the auxiliary air inlet 102, thereby facilitating the disassembly and assembly of the filter 2.

[0060] According to some embodiments of the present invention, referring to Figure 3 and Figure 6, the ratio of the extension length of the auxiliary air inlet 102 in the first direction to the extension length of the main air inlet 101 in the first direction ranges from 1 / 5 to 1 / 12. The ratio of the extension length of the auxiliary air inlet 102 in the first direction to the extension length of the main air inlet 101 in the first direction can be 1 / 9, 1 / 8, 1 / 7 or 1 / 6. By setting the ratio of the extension length of the auxiliary air inlet 102 in the first direction to the extension length of the main air inlet 101 in the first direction to be not less than 1 / 12, it can be ensured that the air intake of the air conditioner is increased through the auxiliary air inlet 102, and it can also be convenient for the user to apply force when disassembling the filter 2, thereby facilitating the disassembly of the filter 2; by setting the ratio of the extension length of the auxiliary air inlet 102 in the first direction to the extension length of the main air inlet 101 in the first direction to be not more than 1 / 5, it can be ensured that the main air inlet 101 covers most of the air intake area, and the main air inlet grille 103 is provided at the main air inlet 101, which can improve the overall structural strength of the housing 1. Therefore, by setting the ratio of the extension length of the auxiliary air inlet 102 in the first direction to the extension length of the main air inlet 101 in the first direction to 1 / 5 to 1 / 12, it can be ensured that the air intake volume of the air conditioner can be increased through the auxiliary air inlet 102, and it can also be convenient for the user to apply force when disassembling the filter 2, thereby facilitating the disassembly of the filter 2; at the same time, it can be ensured that the main air inlet 101 covers most of the air intake area, and the overall structural strength of the casing 1 can be improved.

[0061] According to some embodiments of the present invention, referring to Figure 2-Figure 4 The main air inlet grille 103 is integrally formed with the housing 1. This can improve the overall structural strength of the main air inlet grille 103 and the housing 1, and save the assembly process between the main air inlet grille 103 and the housing 1.

[0062] According to some embodiments of the present invention, the first filter part 21 and the second filter part 22 are integrally formed, which can improve the overall structural strength of the filter 2 and eliminate the assembly process between the first filter part 21 and the second filter part 22, thereby helping to improve the assembly efficiency of the filter 2.

[0063] According to some embodiments of the utility model, the main air inlet grille 103 is integrally formed with the casing 1 and the first filter portion 21 is integrally formed with the second filter portion 22, which can improve the overall structural strength of the main air inlet grille 103 and the casing 1, and can improve the overall structural strength of the filter 2; and the assembly process between the main air inlet grille 103 and the casing 1 is omitted, and the assembly process between the first filter portion 21 and the second filter portion 22 is omitted, which helps to improve the assembly efficiency of the filter 2.

[0064] According to some embodiments of the present invention, referring to Figure 1 and Figure 6The main air inlet 101 and the auxiliary air inlet 102 are separated by a spacing rib 16, and a connecting rib 23 is connected between the first filter part 21 and the second filter part 22, which can ensure the overall structural strength of the filter screen 2.

[0065] Further, refer to Figure 1 , the connecting ribs 23 and the spacing ribs 16 both extend along the second direction, the second direction is perpendicular to the first direction, and the connecting ribs 23 are located inside the spacing ribs 16 and are arranged opposite to the spacing ribs 16. By arranging the connecting ribs 23 inside the spacing ribs 16, the spacing ribs 16 can protect the connecting ribs 23 on the filter screen 2, reducing the extrusion or wear of the connecting ribs 23 on the filter screen 2 by external forces; and the connecting ribs 23 and the spacing ribs 16 are arranged opposite to each other, which can reduce the shielding of the air inlet 11, thereby increasing the air intake at the air inlet 11.

[0066] According to some embodiments of the present invention, referring to Figure 6 The first filter part 21 includes a first filter frame 211 and a first filter part 212 provided on the first filter frame 211. The first filter part 212 plays a filtering role, and the first filter frame plays a supporting role for the first filter part 212. The first filter part 21 is located on the inner side of the main air inlet grille 103. The main air inlet grille 103 plays a protective role for the first filter part 212. The first filter part 212 can further filter the air at the main air inlet 101, thereby improving the air quality.

[0067] According to some embodiments of the present invention, referring to Figure 6 The second filter part 22 includes a second filter frame 221 and a second filter part 222 provided on the second filter frame 221. The second filter part 222 plays a filtering role, and the second filter frame plays a supporting role for the second filter part 222. The second filter part 22 is located in the auxiliary air inlet 102. The second filter part 222 can filter the air at the auxiliary air inlet 102, thereby improving the air quality.

[0068] Furthermore, the outer wall surface of the second filter frame 221 is provided with a convex rib 223 protruding outward, which facilitates the user to apply force when removing the filter 2, thereby facilitating the installation or removal of the filter 2 through the auxiliary air inlet 102. The user can hold the convex rib 223 on the outer wall surface of the second filter frame 221 and push the convex rib 223 from the auxiliary air inlet 102 to the main air inlet 101, so that the filter 2 can be installed to the inner side of the main air inlet grille 103 through the auxiliary air inlet 102; the user can hold the convex rib 223 on the outer wall surface of the second filter frame 221 and pull the convex rib 223 from the main air inlet 101 to the auxiliary air inlet 102, so that the filter 2 can be removed through the auxiliary air inlet 102. In addition, by providing the convex rib 223 on the outer wall surface of the second filter frame 221 of the filter 2, the wind blocking area of ​​the convex rib 223 at the air inlet 11 can be reduced, and the air intake at the air inlet 11 of the air conditioner can be increased.

[0069] According to some embodiments of the present invention, referring to Figure 8 The projection of the rib 223 on the second filter frame 221 is located on the second filter frame 221, so that the rib 223 does not exceed the coverage of the second filter frame 221. In this way, while the rib 223 is provided to facilitate the disassembly and assembly of the filter 2, the rib 223 itself will not cause additional obstruction to the air inlet 11, thereby allowing the air conditioner to have a larger air inlet area to increase the air intake volume at the air inlet 11 of the air conditioner.

[0070] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 A limiting slot 17 is formed on the housing 1, and the limiting slot 17 is located on the side of the main air inlet 101 away from the auxiliary air inlet 102, and one end of the first filter part 21 away from the second filter part 22 is inserted into the limiting slot 17, and one end of the second filter part 22 away from the first filter part 21 is snap-fitted with the housing 1. The limiting slot 17 can limit the first filter part 21, thereby enhancing the stability of the fit between the first filter part 21 and the housing 1.
