For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0049] In addition, the terms "disposed", "connected", and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0050] Unless otherwise stated, the term "plurality" means two or more.

[0051] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0052] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0054] The refrigerant circulation system of the air conditioner is mainly composed of four basic components: compressor, outdoor heat exchanger, throttling device and indoor heat exchanger, forming a closed circulation loop.

[0055] Among them, the compressor is the heart of the refrigerant circulation system. Its main task is to absorb the low-temperature and low-pressure refrigerant gas from the indoor heat exchanger and compress it into a high-temperature and high-pressure gas. After the high-temperature and high-pressure refrigerant gas enters the outdoor heat exchanger, it releases heat to the external environment through heat exchange with the outside air or cooling water, while cooling itself and forming a high-pressure liquid. When the high-pressure liquid passes through the throttling device, part of the liquid will evaporate into gas through throttling and pressure reduction, while absorbing the surrounding heat, further reducing the temperature and pressure of the refrigerant. After the low-pressure refrigerant liquid enters the indoor heat exchanger, it exchanges heat with the hot air in the room. The refrigerant absorbs the heat of the hot air and gradually changes from liquid to gas, while reducing the temperature of the indoor heat exchanger, thereby achieving the purpose of cooling the room.

[0056] In this way, the refrigerant circulates continuously to form a complete refrigeration cycle: the compressor compresses the refrigerant into high-temperature and high-pressure gas, the outdoor heat exchanger cools it into high-pressure liquid, the throttling device reduces the pressure of the refrigerant and partially evaporates it, and the indoor heat exchanger absorbs the indoor heat to evaporate the refrigerant into gas, which enters the compressor again to complete a refrigeration cycle. When heating, the refrigerant flows in the opposite direction. In this way, through the continuous circulation of the refrigerant, the air conditioner can effectively adjust the indoor temperature and provide people with a comfortable indoor environment.

[0057] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides an air conditioner, including a housing 100 and an air outlet assembly. The housing 100 includes a left partition 101, a middle partition 102 and a right partition 103, the three partitions are connected and share the front panel of the housing 100, and the middle partition 102 is provided with a vent 123 on the front panel; the air outlet assembly includes an air outlet duct 110 and a fan, and the fan is arranged in the air outlet duct 110; two air outlet assemblies are respectively arranged in the left partition 101 and the right partition 103, and the air outlets 111 of the two air outlet ducts 110 are both arranged on the front panel; and the tops of the two air outlet ducts 110 are respectively bounded by the top plates of the left partition 101 and the right partition 103 to form a return air duct 120, and the return air duct 120 is connected to the air outlet duct 110; wherein the return air inlet 121 of the return air duct 120 is arranged on the front panel, and the return air inlet 121 is located above the air outlet 111.

[0058] In this embodiment, the air outlet duct 110 and the top plate of the housing 100 are bounded to form a return air duct 120. The air outlet duct 110 has an air outlet inlet 112 and an air outlet 111, and the return air duct 120 has a return air inlet 121 and a return air outlet 122. Figure 1 As shown, the front panel corresponding to the left partition 101 is provided with a return air inlet 121 and an air outlet 111, the front panel corresponding to the right partition 103 is provided with a return air inlet 121 and an air outlet 111, and the front panel corresponding to the middle partition 102 is provided with a vent 123. Figure 6 and Figure 7 As shown, when two fans are running, indoor air enters the corresponding partition through one vent 123 and two return air inlets 121, and is blown into the room through two air outlets 111 after heat exchange with the heat exchanger 150. In this way, two return air inlets 121, two air outlets 111 and one vent 123 are arranged on the front panel, and a forward-to-front-out air flow path is formed, with a large air intake and uniform air outlet. In addition, combined with the partition layout of the housing 100, the entire air conditioner has a compact and beautiful structure.

[0059] Optionally, the fan includes a crossflow blade 130 and a drive motor 140, and the drive motor 140 is used to drive the crossflow blade 130 to rotate. The fan in the left partition 101 is called a first fan 131, and the fan in the right partition 103 is called a second fan 132.

[0060] In this embodiment, the cross-flow blades 130 increase the airflow speed and pressure by changing the airflow from axial to radial, and more effectively promote the air flow, which is conducive to improving the efficiency and performance of the fan. In addition, even if one of the fans fails, the other fan can still continue to work, ensuring that the air conditioner can still maintain a certain air flow capacity, thus improving reliability and fault tolerance.

[0061] Optionally, the first fan 131 and the second fan 132 may operate independently or simultaneously.

[0062] In this embodiment, when the two fans are operated independently, they can supply air to the left or right side of the room separately, which can meet the specific air supply needs of the user and is beneficial to energy saving. When the two fans are operated simultaneously, they supply air to the left and right sides of the room at the same time, which is beneficial to blow the hot and cold air to the entire room faster.

[0063] Exemplarily, after the air conditioner is installed, the space on the left side is larger and the space on the right side is smaller. The operation of the air conditioner includes an overall temperature adjustment stage and a local temperature adjustment stage. In the overall temperature adjustment stage, the first fan 131 and the second fan 132 operate simultaneously, thereby quickly adjusting the overall temperature of the room. Since the space on the left side of the air conditioner is larger than the space on the right side, the temperature of the space on the left side changes slowly. After the temperature on the right side first reaches the preset temperature, the air conditioner enters the local temperature adjustment stage. In the local temperature adjustment stage, only the first fan 131 operates alone, further making the temperature of the space on the left side reach the preset temperature.

[0064] In another exemplary embodiment, after the air conditioner is installed, the space on the left side is smaller and the space on the right side is larger. In the overall temperature adjustment stage, the first fan 131 and the second fan 132 are operated simultaneously, so as to quickly adjust the overall temperature of the room. Since the space on the right side of the air conditioner is larger than the space on the left side, the temperature of the space on the right side changes slowly. After the temperature on the left side reaches the preset temperature first, the air conditioner enters the local temperature adjustment stage. In the local temperature adjustment stage, only the second fan 132 is operated alone, so as to further make the temperature of the space on the right side reach the preset temperature.

[0065] In another example, after the air conditioner is installed, the space on the left side faces the sofa, and the space on the right side faces the dining table. In the overall temperature adjustment stage, the first fan 131 and the second fan 132 operate simultaneously to make the indoor temperature reach the preset temperature. When the user wants to blow cold air further during the meal, the air conditioner enters the local temperature adjustment stage. In the local temperature adjustment stage, only the second fan 132 operates alone to meet the user's blowing needs.

[0066] In another exemplary embodiment, after the air conditioner is installed, the space on the left side faces the sofa, and the space on the right side faces the dining table. In the overall temperature adjustment stage, the first fan 131 and the second fan 132 operate simultaneously to make the indoor temperature reach the preset temperature. When the user lies on the sofa and wants to blow hot air further, the air conditioner enters the local temperature adjustment stage. In the local temperature adjustment stage, only the first fan 131 operates alone, thereby meeting the user's blowing needs.

[0067] Alternatively, if Figure 2As shown, the cross-flow blades 130 of the first fan 131 are disposed in the left partition 101 , and the driving motor 140 of the first fan 131 is disposed in the middle partition 102 .

[0068] In this embodiment, the middle partition 102 is not only used for air circulation, but also provides installation space for the drive motor 140 of the first fan 131. Placing the drive motor 140 of the first fan 131 in the middle partition 102 can make the structure of the entire air conditioner more compact. This design not only saves space, but also can dissipate heat for the drive motor 140 of the first fan 131 when the indoor air flows through the middle partition 102.

[0069] Optionally, a first motor base is provided in the middle section 102 , and the first motor base is used to install a driving motor 140 of the first fan 131 .

[0070] Alternatively, if Figure 2 As shown, the cross-flow blades 130 of the second fan 132 are disposed in the right partition 103 , and the driving motor 140 of the second fan 132 is disposed in the middle partition 102 .

[0071] In this embodiment, the middle partition 102 is not only used for air circulation, but also provides installation space for the drive motor 140 of the second fan 132. Placing the drive motor 140 of the second fan 132 in the middle partition 102 can make the structure of the entire air conditioner more compact. This design not only saves space, but also can dissipate heat for the drive motor 140 of the second fan 132 when the indoor air flows through the middle partition 102.

[0072] For example, Figure 2 As shown, the driving motor 140 of the first fan 131 and the driving motor 140 of the second fan 132 are relatively arranged in the middle section 102. In this way, the installation space is effectively saved, the volume of the air conditioner is reduced, and the indoor air flows through the middle section 102 to dissipate heat for the two driving motors 140 at the same time.

[0073] Optionally, a second motor base is provided in the middle section 102 , and the second motor base is used to install a driving motor 140 of the second fan 132 .

[0074] Alternatively, if Figure 3 As shown, a first motor room 133 is provided on the left side of the left partition 101 ; the cross-flow blades 130 of the first fan 131 are disposed in the left partition 101 , and the driving motor 140 of the first fan 131 is disposed in the first motor room 133 .

[0075] In this embodiment, the first motor room 133 and the three partitions share the front panel of the housing 100, and the first motor room 133 is provided with a first inspection port on the front panel. The drive motor 140 of the first fan 131 is placed in the motor room, and the drive motor 140 can be easily maintained and replaced from the first inspection port. In addition, the first motor room 133 can serve as a soundproof barrier to effectively isolate or reduce the noise generated by the drive motor 140, thereby improving the quiet performance of the air conditioner.

[0076] Optionally, a first motor seat is provided in the first motor chamber 133 , and the first motor seat is used to install the driving motor 140 of the first fan 131 .

[0077] Alternatively, if Figure 3 As shown, a second motor room 134 is disposed on the right side of the right partition 103 ; the cross-flow blades 130 of the second fan 132 are disposed in the right partition 103 , and the driving motor 140 of the second fan 132 is disposed in the second motor room 134 .

[0078] In this embodiment, the second motor room 134 shares the front panel of the housing 100 with the three partitions, and the second motor room 134 has a second inspection port on the front panel. The drive motor 140 of the second fan 132 is placed in the motor room, and the drive motor 140 can be easily maintained and replaced from the second inspection port. In addition, the second motor room 134 can serve as a soundproof barrier to effectively isolate or reduce the noise generated by the drive motor 140, thereby improving the quiet performance of the air conditioner.

[0079] Optionally, a second motor base is provided in the second motor chamber 134 , and the second motor base is used to install the driving motor 140 of the second fan 132 .

[0080] Optionally, one of the driving motor 140 of the first fan 131 and the driving motor 140 of the second fan 132 is disposed in the middle section 102, and the other is disposed in a corresponding motor room.

[0081] In this embodiment, the positions of the two motors can be reasonably arranged according to the needs of the user and the limitation of the installation space, so that the air conditioner has good flexibility and scalability and is applicable to a wider range of scenarios.

[0082] For example, Figure 4 As shown, the driving motor 140 of the first fan 131 is disposed in the middle section 102, and the driving motor 140 of the second fan 132 is disposed in the second motor chamber 134. In this way, when the indoor air flows through the middle section 102, the driving motor 140 of the first fan 131 can be cooled. In addition, the second motor chamber 134 can serve as a soundproof barrier to effectively isolate or reduce the noise generated by the driving motor 140 of the second fan 132.

[0083] In another exemplary embodiment, the driving motor 140 of the first fan 131 is disposed in the first motor room 133, and the driving motor 140 of the second fan 132 is disposed in the middle section 102. In this way, the first motor room 133 can serve as a soundproof barrier to effectively isolate or reduce the noise generated by the driving motor 140 of the first fan 131. In addition, when the indoor air flows through the middle section 102, the driving motor 140 of the second fan 132 can be cooled.

[0084] Alternatively, if Figure 5 As shown, the return air inlet 121 is arranged adjacent to the air outlet 111 , and the return air inlet 121 extends upward from its bottom to form a wind shield 124 .

[0085] In this embodiment, the return air inlet 121 is arranged adjacent to the air outlet 111, so that the air outlet on the front panel is relatively compact. In addition, under the action of the wind shield 124, there is a shielding member of appropriate height between the return air inlet 121 and the air outlet 111, which can prevent the occurrence of air duct short circuit to a certain extent and ensure the normal operation of the air conditioner.

[0086] Optionally, the wind shield 124 is parallel to the front panel of the housing 100. In this way, the front of the air conditioner is relatively flat, and the aesthetics are improved.

[0087] Optionally, the air conditioner further includes a heat exchanger 150 . The first end of the heat exchanger 150 is located at the air outlet inlet 112 of the air outlet duct 110 of the left partition 101 , the second end of the heat exchanger 150 is located at the air outlet inlet 112 of the air outlet duct 110 of the right partition 103 , and the center of the heat exchanger 150 is located in the middle partition 102 .

[0088] In this embodiment, if Figure 7 As shown, since the three partitions are connected, the indoor air enters the middle partition 102 through the vent 123 and exchanges heat with the heat exchanger 150. The air after heat exchange is blown into the room through the air outlet ducts 110 of the left partition 101 and the right partition 103. In this way, the layout of the heat exchanger 150 increases the heat exchange area and efficiency, which is conducive to the air conditioner reaching the set temperature faster and improving the cooling or heating effect. In addition, since the same heat exchanger 150 spans the air outlet ducts 110 of the two partitions, it can ensure that the temperature of the air outlets 111 on both sides is more balanced, which is conducive to improving the uniformity of the indoor temperature and reducing the temperature difference of the air outlets 111 on both sides.

[0089] Optionally, the heat exchanger 150 entirely covers the air outlet inlets 112 of the two air outlet ducts 110 .

[0090] In this embodiment, since the heat exchanger 150 directly covers the air outlet inlet 112 of the air outlet duct 110, heat loss or leakage caused by connection or sealing problems can be reduced. This is conducive to improving the reliability and stability of the system. In addition, the overall coverage allows the heat exchanger 150 to adapt to air outlet ducts 110 of different sizes and shapes, providing flexibility for the design of various air outlet ducts 110.

[0091] Alternatively, if Figure 5 and Figure 6 As shown, a mounting plate 113 is provided at the return air outlet 122 of the return air duct 120 , and the top of the heat exchanger 150 is against the lower plate surface of the mounting plate 113 .

[0092] In this embodiment, since the top of the heat exchanger 150 is closely attached to the mounting plate 113, the air is guided to the heat exchanger 150 when flowing through the return air outlet 122, thereby ensuring sufficient contact between the air and the heat exchanger 150. This helps to improve the heat exchange efficiency. In addition, the mounting plate 113 provides a stable mounting platform to ensure that the heat exchanger 150 can be firmly mounted on the return air duct 120.

[0093] Optionally, a supporting plate is provided at the air outlet inlet 112 of the air outlet duct 110 , and the bottom of the heat exchanger 150 abuts against the upper surface of the supporting plate.

[0094] In this embodiment, the top of the heat exchanger 150 is fixed by the mounting plate 113, and the bottom of the heat exchanger 150 is fixed by the supporting plate. In this way, the top and bottom of the heat exchanger 150 are effectively fixed, which can prevent the heat exchanger 150 from being displaced or loosened due to vibration or external force during operation, thereby ensuring the stable operation of the air conditioner.
