[0048] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which the same or similar elements have the same or similar reference numbers. The embodiments described below are examples only, and are not to be construed as limiting the present application.

[0049] Reference is made below to Figures 1-16 An air conditioner 1000 according to an embodiment of the present application is described below.

[0050] As Figures 1-6As shown, the air conditioner 1000 according to the embodiment of the present application comprises a housing 100, a first heat exchanger 300, a first fan assembly 400, a second heat exchanger 500, a second fan assembly 600 and a compressor 700. The housing 100 can provide mounting space for the first heat exchanger 300, the first fan assembly 400, the second heat exchanger 500, the second fan assembly 600 and the compressor 700; the first heat exchanger 300 and the second heat exchanger 500 can be filled with refrigerant, and the first heat exchanger 300 and the second heat exchanger 500 can be used for refrigeration or heating through vaporization or liquefaction of the refrigerant; the first fan assembly 400 and the second fan assembly 600 can drive air flow; and the compressor 700 can provide power for the refrigeration cycle of the air conditioner 1000 and output high-temperature and high-pressure gas.

[0051] Specifically, referring to Figure 2 , the housing 100 defines a first air duct 110 and a second air duct 120, and the first air duct 110 and the second air duct 120 are arranged in a horizontal direction. The housing 100 has a first air inlet 130 and a first air outlet 140 which communicate with the first air duct 110, and the housing 100 is further provided with a second air inlet 150 and a second air outlet 160 which communicate with the second air duct 120. The first heat exchanger 300 is arranged in the first air duct 110, and the two ends of the first heat exchanger 300 are connected to the housing 100 by fasteners. Thus, the first heat exchanger 300 can be reliably mounted in the housing 100, and the first heat exchanger 300 is easy to be mounted in and removed from the housing 100, thereby improving the maintainability of the first heat exchanger 300. The first fan assembly 400 is arranged in the first air duct 110 to drive air flow from the first air inlet 130 to the first air outlet 140.

[0052] The second heat exchanger 500 is arranged in the second air duct 120, and one of the first heat exchanger 300 and the second heat exchanger 500 is a condenser, and the other is an evaporator. When the first heat exchanger 300 is the condenser, the second heat exchanger 500 is the evaporator; when the first heat exchanger 300 is the evaporator, the second heat exchanger 500 is the condenser. The refrigerant can be liquefied and released heat in the condenser, and vaporized and absorbed heat in the evaporator, thereby enabling the refrigeration cycle of the air conditioner 1000 to proceed smoothly. Here, the first heat exchanger 300 is taken as the evaporator and the second heat exchanger 500 is taken as the condenser for description, which cannot be understood as a limitation to the present application. The two ends of the second heat exchanger 500 are connected to the housing 100 by fasteners. Thus, the second heat exchanger 500 can be reliably mounted in the housing 100, and the second heat exchanger 500 is easy to be mounted in and removed from the housing 100, thereby improving the maintainability of the second heat exchanger 500.

[0053] The second fan assembly 600 is arranged in the second air duct 120 to drive the air flow from the second air inlet 150 to the second air outlet 160. The compressor 700 is arranged in one of the first air duct 110 and the second air duct 120, and the compressor 700, the first heat exchanger 300 and the second heat exchanger 500 form a heat exchange flow path, in which the compressor 700 transmits the high-temperature and high-pressure refrigerant to the second heat exchanger 500, the refrigerant is liquefied and heat is released in the second heat exchanger 500, so that the temperature of the air flow outside the second heat exchanger 500 is increased; the liquefied refrigerant flows to the first heat exchanger 300, and the refrigerant is vaporized and heat is absorbed in the first heat exchanger 300, so that the temperature of the air flow outside the first heat exchanger 300 is decreased.

[0054] It can be understood that when the air conditioner 1000 is cooling, the indoor hot air flow enters the first air duct 110 from the first air inlet 130, and the hot air flow exchanges heat with the first heat exchanger 300 when passing through the first heat exchanger 300, and becomes cold air flow after entering the first fan assembly 400, and the first fan assembly 400 drives the cold air flow to flow to the first air outlet 140, so that the cold air flow can flow to the indoor from the first air outlet 140 to cool the indoor; in order to enable the cooling cycle of the air conditioner 1000 to continuously operate, the indoor air flow also enters the second air duct 120 from the second air inlet 150, and the air flow exchanges heat with the second heat exchanger 500 when passing through the second heat exchanger 500, and becomes hot air flow after entering the second fan assembly 600, and the second fan assembly 600 drives the hot air flow to flow to the second air outlet 160, so that the hot air flow can flow to the indoor from the second air outlet 160, at this time, a heat pipe can be installed at the second air outlet 160 to guide the hot air flow out of the indoor, or the hot air flow flowing to the indoor can not be processed, which is not specifically limited here.

[0055] In the related art, most air conditioners separate the indoor unit and the outdoor unit, the indoor heat exchanger is arranged in the indoor unit, and the outdoor heat exchanger is arranged in the outdoor unit. The air conditioner with separated indoor unit and outdoor unit is complex to install, and needs to be punched on the wall, which damages the home decoration. A few integrated air conditioners with the indoor heat exchanger and the outdoor heat exchanger arranged in one shell have complex air duct design, which leads to large size of the air conditioner and large indoor area occupied when placed, and the heat exchanger is not easy to replace and maintain when damaged.

[0056] According to the air conditioner 1000 of the embodiment of the present application, the first air duct 110 and the second air duct 120 are arranged horizontally in the shell 100, the first heat exchanger 300 and the first fan assembly 400 are arranged in the first air duct 110, the first heat exchanger 300 is connected to the shell 100 by a threaded fastener, so that the hot air flow entering the first air duct 110 from the first air inlet 130 can be converted into cold air flow to be blown out from the first air outlet 140 when the first air duct is cooling; the second heat exchanger 500 and the second fan assembly 600 are arranged in the second air duct 120, the second heat exchanger 500 is connected to the shell 100 by a threaded fastener, so that the air flow entering the air duct from the second air inlet 150 can be converted into hot air flow to be blown out from the second air outlet 160 when the first air duct is cooling, thereby ensuring the smooth progress of the cooling cycle.

[0057] The air conditioner 1000 of the present application arranges the first air duct 110 and the second air duct 120 on the shell 100, the cooling in the first air duct 110 and the heating in the second air duct 120 can not interfere with each other, so that the air conditioner 1000 has simple structure and is easy to install, without the need to punch holes in the wall, and the integrity and beauty of the home decoration can be maintained. Moreover, the horizontal arrangement of the first air duct 110 and the second air duct 120 makes the structure of the air conditioner 1000 smaller, so that the indoor area can be saved when placing. In addition, the threaded fastener connection of the first heat exchanger 300 and the second heat exchanger 500 to the shell 100 can improve the replaceability and maintainability of the first heat exchanger 300 and the second heat exchanger 500.

[0058] Further, as shown in Figure 7 、 Figure 9 and Figures 11-12 , the shell 100 can have first connecting holes 250, the first heat exchanger 300 and the second heat exchanger 500 can each have second connecting holes 340, the first connecting holes 250 correspond to the second connecting holes 340 one by one, and the fastener can be arranged in the first connecting holes 250 and the second connecting holes 340, so as to fix the first heat exchanger 300 and the second heat exchanger 500 to the shell 100 respectively, thereby reliably installing the first heat exchanger 300 and the second heat exchanger 500 in the shell 100.

[0059] In some embodiments of the present application, reference is made to Figure 7The bottom wall of the shell 100 is provided with a first supporting rib 210 for supporting the first heat exchanger 300 and a second supporting rib 220 for supporting the second heat exchanger 500. The first supporting rib 210 extends along the extension direction of the first heat exchanger 300, and the second supporting rib 220 extends along the extension direction of the second heat exchanger 500. It can be understood that the first supporting rib 210 is arranged in the first air duct 110, and the second supporting rib 220 is arranged in the second air duct 120. The first supporting rib 210 can stably support the first heat exchanger 300, so that the first heat exchanger 300 can be reliably installed in the shell 100. The second supporting rib 220 can stably support the second heat exchanger 500, so that the second heat exchanger 500 can be reliably installed in the shell 100.

[0060] In some embodiments of the present application, as shown in Figure 2 and Figure 5 , the first heat exchanger 300 and the second heat exchanger 500 are oppositely arranged, so that the layout of the first heat exchanger 300 and the second heat exchanger 500 is reasonably compact, and the product volume of the air conditioner 1000 can be reduced. The first fan assembly 400 is arranged on the side of the first heat exchanger 300 facing the second heat exchanger 500, and the second fan assembly 600 is arranged on the side of the second heat exchanger 500 facing the first heat exchanger 300. It can be understood that in the first air duct 110, the airflow flows from the side of the first heat exchanger 300 away from the second heat exchanger 500 to the side of the first heat exchanger 300 facing the second heat exchanger 500. The first fan assembly 400 arranged on the side of the first heat exchanger 300 facing the second heat exchanger 500 can facilitate driving the airflow to flow from the first air inlet 130 to the first air outlet 140, thereby improving the heat exchange efficiency of the first heat exchanger 300. In the second air duct 120, the airflow flows from the side of the second heat exchanger 500 away from the first heat exchanger 300 to the side of the second heat exchanger 500 facing the first heat exchanger 300. The second fan assembly 600 arranged on the side of the second heat exchanger 500 facing the first heat exchanger 300 can facilitate driving the airflow to flow from the second air inlet 150 to the second air outlet 160, thereby improving the heat exchange efficiency of the second heat exchanger 500.

[0061] Further, referring to Figure 2 and Figure 5 , the first heat exchanger 300 and the second heat exchanger 500 have the same shape. Therefore, the installation and replacement of the first heat exchanger 300 and the second heat exchanger 500 can be facilitated, and the versatility of the air conditioner 1000 is better.

[0062] According to some embodiments of the present application, as shown in Figure 2As shown, the first heat exchanger 300 and the second heat exchanger 500 each include a first section 310 and a second section 320, the first section 310 and the second section 320 are at an angle to each other, and the first heat exchanger 300 and the second heat exchanger 500 protrude towards directions away from each other. In this way, the heat exchange area of the first heat exchanger 300 and the second heat exchanger 500 can be increased, so that the heat exchange efficiency of the first heat exchanger 300 and the second heat exchanger 500 can be improved. Further, the first section 310 and the second section 320 are connected by a circular arc section 330, so that the first section 310 and the second section 320 can be smoothly connected, and thus the first heat exchanger 300 and the second heat exchanger 500 are facilitated to be installed in the shell 100, and the probability of the first heat exchanger 300 and the second heat exchanger 500 being scratched can be reduced.

[0063] In some embodiments of the present application, as shown in Figure 2 As shown, the shell 100 includes opposite first and second side walls 170 and 180, and opposite third and fourth side walls 190 and 200, the third side wall 190 is connected between one end of the first side wall 170 and one end of the second side wall 180, and the fourth side wall 200 is connected between the other end of the first side wall 170 and the other end of the second side wall 180, so that the first, second, third and fourth side walls 170, 180, 190 and 200 can form a mounting space, so that the first heat exchanger 300, the first fan assembly 400, the second heat exchanger 500, the second fan assembly 600 and the compressor 700 can be installed in the mounting space.

[0064] As shown, the first section 310 and the second section 320 of the first heat exchanger 300 are parallel to the first side wall 170 and the third side wall 190 respectively, and the first section 310 and the second section 320 of the second heat exchanger 500 are parallel to the second side wall 180 and the fourth side wall 200 respectively, and it should be noted that the first air inlet 130 can be arranged at positions on the first side wall 170 and the third side wall 190 corresponding to the first section 310 and the second section 320 of the first heat exchanger 300, and the second air inlet 150 can be arranged at positions on the second side wall 180 and the fourth side wall 200 corresponding to the first section 310 and the second section 320 of the second heat exchanger 500, so that the arrangement positions of the first heat exchanger 300 and the second heat exchanger 500 on the shell 100 can be inhaled air, so that the heat exchange amount of the airflow and the first heat exchanger 300 and the second heat exchanger 500 can be increased, so that the heat exchange efficiency of the first heat exchanger 300 and the second heat exchanger 500 can be improved.

[0065] According to some embodiments of the present application, as shown in Figures 5-6As shown, both the first heat exchanger 300 and the second heat exchanger 500 are formed in the shape of a flat plate, which facilitates the manufacture of the first heat exchanger 300 and the second heat exchanger 500, and also facilitates the installation of the first heat exchanger 300 into the first air duct 110 and the second heat exchanger 500 into the second air duct 120.

[0066] Combination Figures 5-6 In some embodiments of the present invention, the housing 100 includes a first sidewall 170 and a second sidewall 180 opposite each other, the first heat exchanger 300 is parallel to the first sidewall 170, and the second heat exchanger 500 is parallel to the second sidewall 180. This facilitates the arrangement of the first heat exchanger 300 and the second heat exchanger 500 and can improve the space utilization of the housing 100.

[0067] Furthermore, such as Figures 5-6 As shown, the first heat exchanger 300 and the second heat exchanger 500 are both vertically arranged and are located adjacent to the inner sidewall of the shell 100. The first air inlet 130 and the second air inlet 150 are both located on the sidewall of the shell 100. This allows for more effective use of the space in the shell 100. Furthermore, the first heat exchanger 300 is closer to the first air inlet 130, and the second heat exchanger 500 is closer to the second air inlet 150. This allows the first heat exchanger 300 and the second heat exchanger 500 to exchange heat with the airflow more quickly after air is introduced. The first air inlet 130 is opposite to the first heat exchanger 300 and extends along the extension direction of the first heat exchanger 300, and the second air inlet 150 is opposite to the second heat exchanger 500 and extends along the extension direction of the second heat exchanger 500. As a result, the heat exchange between the airflow and the first heat exchanger 300 and the second heat exchanger 500 can be increased, thereby improving the heat exchange efficiency of the first heat exchanger 300 and the second heat exchanger 500.

[0068] According to some embodiments of the present invention, such as Figures 5-6 As shown, both the first air outlet 140 and the second air outlet 160 are located on the side wall of the housing 100. The first air outlet 140 is located between one end of the first air inlet 130 and one end of the second air inlet 150, and the second air outlet 160 is located between the other end of the first air inlet 130 and the other end of the second air inlet 150. It can be understood that the airflow from the first air outlet 140 is cold air, and the airflow from the second air outlet 160 is hot air. Spacing the first air outlet 140 and the second air outlet 160 apart can reduce their mutual influence.

[0069] Combination Figures 2-6In some embodiments of the present application, the first fan assembly 400 comprises a first motor 410 and a first impeller 420, the first impeller 420 is connected with the first motor 410, the first impeller 420 is a centrifugal impeller, the axis of the centrifugal impeller extends in the vertical direction, and the two axial ends of the centrifugal impeller are configured as first impeller inlets 421. The first motor 410 can drive the first impeller 420 to rotate, the rotation of the first impeller 420 can drive the airflow to flow from the first air inlet 130 to the first air outlet 140, the air inlet at the two axial ends of the centrifugal impeller can make more cold air flow to the first air outlet 140, and then to the indoor, and also make more airflow to exchange heat with the first heat exchanger 300, thereby improving the refrigeration effect of the air conditioner 1000.
