[0039] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0040] As shown in Figure 1 and Figure 2 The air conditioner of the embodiment of the present application comprises a shell 1, a heat exchanger 2 and a centrifugal fan 3.

[0041] The shell 1 comprises a panel 11 and a side plate 12, the side plate 12 is arranged at the end of the length direction of the shell 1, the side plate 12 is provided with a side air inlet 121, the side air inlet 121 is arranged at the bottom of the side plate 12 and adjacent to the panel 11, the panel 11 is provided with an air outlet 111, the air outlet 111 is adjacent to the top side of the panel 11.

[0042] For example, as shown in Figure 1 The shell 1 can be generally cuboid, the length direction of the shell 1 can be the left-right direction, the panel 11 can be the shell wall part of the front side of the shell 1, and the side plate 12 can be the shell wall part of the left side or the right side of the shell 1.

[0043] The shell 1 can comprise two side plates 12, the two side plates 12 can be arranged opposite in the left-right direction, the side air inlet 121 can be arranged on each side plate 12, and the side air inlet 121 can be arranged at the lower corner position of each side plate 12. The air outlet 111 can be a square opening, the air outlet 111 can be arranged at the top of the panel 11 and can extend along the left-right direction.

[0044] The heat exchanger 2 is arranged in the shell 1 and divides the inner cavity of the shell 1 into a lower cavity 13 and an upper cavity 14 arranged opposite in the up-down direction, the side air inlet 121 and the lower cavity 13 are in communication, and the air outlet 111 and the upper cavity 14 are in communication.

[0045] For example, as shown in Figure 2 The heat exchanger 2 can be a plate structure, and specifically can be an evaporator or a condenser. When it is an evaporator, the heat exchanger 2 can cool and cool the airflow, thereby meeting the use needs of indoor cooling. When it is a condenser, the heat exchanger 2 can heat and heat the airflow, thereby meeting the use needs of indoor heating.

[0046] The heat exchanger 2 can be installed in the shell 1 and can be arranged obliquely downward along the front-up to back-down direction. The outer peripheral side of the heat exchanger 2 can be sealingly connected with the corresponding inner wall of the shell 1, so as to avoid the case that the air flow flows through the gap between the heat exchanger 2 and the inner wall of the shell 1, and to improve the heat exchange effect.

[0047] It should be noted that the heat exchanger 2 can divide the shell 1 into two relatively independent chambers, that is, a lower chamber 13 located below the heat exchanger 2 and an upper chamber 14 located above the heat exchanger 2. The two side air inlets 121 on the two side plates 12 can be respectively communicated with the left side and the right side of the lower chamber 13, and the air outlet 111 can be communicated with the upper chamber 14.

[0048] As shown in Figure 2 The centrifugal fan 3 is arranged in the upper chamber 14, and the centrifugal fan 3 is connected with the air outlet 111 and is used for discharging the air flow in the upper chamber 14 through the air outlet 111. Specifically, when the centrifugal fan 3 operates, the external air flow can first flow into the lower chamber 13 through the two side air inlets 121, and then the air flow flows through the heat exchanger 2 and exchanges heat with the heat exchanger 2, so as to realize heating or cooling of the air flow. The temperature-adjusted air flow enters the upper chamber 14, and then is transported to the air outlet 111 under the action of the centrifugal fan 3 and is discharged through the air outlet 111.

[0049] The air conditioner of the embodiment of the utility model, the side air inlet 121 is arranged on the side plate 12 of the air conditioner, and the air outlet 111 is arranged on the panel 11 of the air conditioner, so that the air inlet direction and the air outlet direction are not in the same plane, thereby avoiding the case that the outlet air flow is easily sucked back by the air inlet, and improving the overall temperature adjustment effect of the air conditioner.

[0050] Secondly, the centrifugal fan 3 also has greater static pressure capacity than the conventional cross-flow fan, and can make the air flow blow farther under the same air volume, so as to strengthen the settling refrigeration effect of the air flow discharged through the air outlet 111, and when heating, the hot air flow can better reach the ground and form a warm foot wind effect, thereby improving the user experience.

[0051] In addition, by adopting the centrifugal fan 3 and arranging the air inlet on the side plate 12, the overall size of the air conditioner can be reduced, the volume of the air conditioner is reduced, the miniaturization of the air conditioner is realized, and the use needs of temperature adjustment in a small space environment are met.

[0052] In some embodiments, the air conditioner comprises a guide vane 4, which is rotationally assembled at the air outlet 111, and the guide vane 4 is used for swinging adjustment to different inclination angles to adjust the outflow direction of the air flow of the air outlet 111.

[0053] For example, as shown in Figure 2As shown, the air deflector 4 can be a rectangular plate, and the air deflector 4 is pivotally assembled with the shell 1 along the left-right direction, wherein the pivot of the air deflector 4 can be arranged along the left-right direction. Thus, the air deflector 4 can be adjusted to swing in the front-up to back-down direction, thereby meeting the use requirement of adjusting the outflow direction of the air flow.

[0054] In some embodiments, the air conditioner includes a heating mode and a cooling mode, and in the cooling mode, the air deflector 4 is arranged to tilt upward to make the air flow of the air outlet 111 tilt upward. For example, as shown in FIG. (a) of Figure 3 As shown, the air deflector 4 can be a rectangular plate, and the air deflector 4 is pivotally assembled with the shell 1 along the left-right direction, wherein the pivot of the air deflector 4 can be arranged along the left-right direction. Thus, the air deflector 4 can be adjusted to swing in the front-up to back-down direction, thereby meeting the use requirement of adjusting the outflow direction of the air flow.

[0055] In the heating mode, the air deflector 4 is arranged to tilt downward to make the air flow of the air outlet 111 tilt downward. For example, as shown in FIG. (b) of Figure 3 As shown, the air deflector 4 can be a rectangular plate, and the air deflector 4 is pivotally assembled with the shell 1 along the left-right direction, wherein the pivot of the air deflector 4 can be arranged along the left-right direction. Thus, the air deflector 4 can be adjusted to swing in the front-up to back-down direction, thereby meeting the use requirement of adjusting the outflow direction of the air flow.

[0056] In some embodiments, as shown in FIG. (a) of Figure 4 As shown, the air deflector 4 can be a rectangular plate, and the air deflector 4 is pivotally assembled with the shell 1 along the left-right direction, wherein the pivot of the air deflector 4 can be arranged along the left-right direction. Thus, the air deflector 4 can be adjusted to swing in the front-up to back-down direction, thereby meeting the use requirement of adjusting the outflow direction of the air flow.

[0057] The shell 1 includes a back plate 15 arranged opposite to the panel 11, one side of the heat exchanger body 21 is connected with the panel 11, and the other side of the heat exchanger body 21 is connected with the back plate 15. The shell 1 includes two side plates 12 arranged opposite in the length direction, and the heat exchanger body 21 is located between the two side plates 12.

[0058] For example, the panel 11 can be a shell wall part of the front side of the shell 1, the back plate 15 can be a shell wall part of the rear side of the shell 1, and the panel 11 and the back plate 15 can be arranged opposite in the front-rear direction. The heat exchanger body 21 can be generally a rectangular plate structure, the front side edge of the heat exchanger body 21 can be connected and fixed with the panel 11, and the rear side edge of the heat exchanger body 21 can be connected and fixed with the back plate 15, thereby ensuring the connection and sealing of the front side and the rear side of the heat exchanger body 21, and avoiding the air flow through the gap between the front side and the rear side of the heat exchanger body 21.

[0059] The heat exchanger body 21 is provided with a side plate 22 between each of the two ends along the length direction and the corresponding side plate 12. For example, as shown in Figure 4 , the side plate 22 can be provided with two, both of which can be in the form of an angle plate, one of which can be connected between the left side of the heat exchanger body 21 and the left side plate 12, and the other can be connected between the right side of the heat exchanger body 21 and the right side plate 12.

[0060] The provision of the side plate 22 on the one hand facilitates the installation and fixation of the heat exchanger body 21, and on the other hand the side plate 22 can also play a role in plugging the gap between the heat exchanger body 21 and the corresponding side plate 12, avoiding the case where the airflow does not flow through the heat exchanger body 21 but directly flows into the upper cavity 14, and ensuring the heat exchange effect.

[0061] In some embodiments, the heat exchanger 2 is arranged obliquely downward along the direction from the front panel 11 to the back panel 15, the side inlet 121 has an oblique port edge extending along the oblique direction of the heat exchanger 2, and the projection of the lower surface of the side plate 22 on the side plate 12 is higher than or flush with the projection of the oblique port edge on the side plate 12.

[0062] For example, as shown in Figure 5 , the heat exchanger 2 can be arranged obliquely downward along the direction from the front up to the back down. The side inlet 121 can be generally in the form of a trapezoidal opening, and the oblique port edge is the obliquely arranged hypotenuse port edge of the upper side of the side inlet 121, and the oblique port edge is also arranged obliquely downward along the direction from the front up to the back down, and the oblique port edge can be specifically as shown by L1 in Figure 5 .

[0063] The side plate 22 can be generally in the form of an angle plate, and the side plate 22 can include a first plate portion and a second plate portion, wherein the first plate portion can be generally in the same plane as the surface of the heat exchanger body 21, and the second plate portion can be a vertical plate and can be in contact with the left or right end surface of the heat exchanger body 21, and the first plate portion can be connected to the upper side edge of the second plate portion. The lower surface of the above-mentioned side plate 22 can only be the lower surface of the first plate portion.

[0064] For simplicity of description, a straight line on the lower surface of the first plate portion can be taken as an example, which can be the inside intersection of the first plate portion and the second plate portion, which can be specifically as shown by L2 in Figure 5 .

[0065] As shown in Figure 5 , a plane YZ can be defined, wherein Y can be an axis extending in the front-back direction, and Z can be an axis extending in the up-down direction, and the plane YZ is parallel to the side plate 12. The projection of the oblique port edge on the plane YZ can be a straight line L1a, and the projection of the inside intersection on the plane YZ can be a straight line L2a.

[0066] As can be seen from Figure 6 , in the case of the same corresponding Y value, the distance between the corresponding point on the projection L1a and the Y axis can be a2, and the distance between the corresponding point on the projection L2a and the Y axis can be a1, where a1 is always greater than a2, that is, the projection L1a is always located below the projection L2a.

[0067] Thus, the side plate 22 can block the upper part of the side air inlet 121, so that the airflow can only flow through the heat exchanger body 21, avoiding the case that the airflow directly passes through the heat exchanger body 21 through the gap between the heat exchanger body 21 and the side plate 12, and ensuring the heat exchange effect.

[0068] In some embodiments, the angle between the inclined edge and the horizontal direction is angle a, and a≥45°. Specifically, as shown in Figure 6 , the angle between the inclined edge and the horizontal direction can be Figure 6 , the angle between the projection L2a and the Y axis in

[0069] Thus, under the condition of ensuring the refrigeration working condition, the condensed water on the heat exchanger 2 can flow along the fins of the heat exchanger 2 to the water pan 5, and the wall surface of the condensed water directly separates from the fins of the heat exchanger 2 and falls to the bottom of the shell 1, ensuring the drainage effect of the heat exchanger 2.

[0070] In some embodiments, the air conditioner comprises a water pan 5, the water pan 5 is integrated with the back plate 15 and extends along the length direction, the panel 11 is provided with a support 112, one side of the heat exchanger body 21 is lapped on the support 112, and the other side of the heat exchanger body 21 is lapped on the water pan 5.

[0071] For example, as shown in Figure 4 , the water pan 5 can be a V-shaped plate, the water pan 5 can be integrally formed on the front side of the back plate 15 and can be arranged to extend along the left-right direction. The support 112 can be a strip-shaped structure, the support 112 can be integrally formed on the rear side of the panel 11 and arranged to extend along the left-right direction. During assembly, the front side of the heat exchanger body 21 can be lapped and fixed above the support 112, and the rear side of the heat exchanger body 21 can be lapped and fixed above the water pan 5.

[0072] Thus, the use requirement of sealing assembly of the front side and the rear side of the heat exchanger body 21 is ensured, the leakage of the airflow is avoided, and the installation and fixation of the heat exchanger body 21 are facilitated. Secondly, the condensed water on the heat exchanger body 21 is facilitated to flow directly to the water pan 5 along the heat exchanger body 21, and the collection of the condensed water is facilitated.

[0073] In some embodiments, the centrifugal fan 3 comprises a fan wheel 31, a volute 32 and a motor 33.

[0074] For example, as shown in Figure 4 The volute 32 can have a whole whistle structure, and the volute 32 comprises a cylindrical portion and a straight tube portion. The cylindrical portion extends along the left-right direction, the straight tube portion is connected with the cylindrical portion and extends along the front-rear direction, and the rear end of the straight tube portion can be connected with the cylindrical portion, and the front end of the straight tube portion can be connected with the air outlet 111.

[0075] The fan wheel 31 can be rotatably arranged in the cylindrical portion, the driving shaft of the motor 33 can extend along the left-right direction and can pass through the cylindrical portion, and the fan wheel 31 can be fixed on the driving shaft. As shown in Figure 4 The motor 33 can be located on the right side of the fan wheel 31 as a whole, and the motor 33 can be fixedly connected with the right side plate 12 through fasteners. The driving shaft of the motor 33 can pass out of the left side of the volute 32 and can be rotatably arranged in the left side plate 12 through a bearing. Thus, the use requirement of driving the airflow to flow is met.

[0076] In some embodiments, the fan wheel 31 and the volute 32 are both provided with a plurality of volutes 32, and the plurality of volutes 32 are arranged in the upper cavity 14, connected with the air outlet 111 and arranged along the length direction. The plurality of fan wheels 31 are correspondingly arranged in the plurality of volutes 32, and the motor 33 is arranged between two adjacent fan wheels 31.

[0077] For example, as shown in Figure 8 The fan wheel 31 and the volute 32 can both be provided with three volutes 32, and the three volutes 32 can have the same structure and can be arranged along the left-right direction. The three fan wheels 31 can be respectively arranged in the three volutes 32. The motor 33 can be arranged between two volutes 32 along the left-right direction, and there can be two volutes 32 on the left side of the motor 33 and only one volute 32 on the right side of the motor 33.

[0078] Therefore, the structure design of the plurality of centrifugal fans 3 in parallel is realized, the overall pumping strength can be improved, the air supply distance of the airflow can be increased, and the circulation efficiency of the indoor gas can be increased.

[0080] For example, asFigure 8 As shown, the support frame 7 can be fixed to the front side of the back plate 15 and located above the water tray 5. The support frame 7 is generally a semi-cylindrical structure, and the pressure cover 8 can also be a semi-cylindrical structure. The pressure cover 8 can be fixed to the front side of the support frame 7 with fasteners. The motor 33 can be fixed within the space enclosed by the support frame 7 and the pressure cover 8. This facilitates the installation and fixing of the motor 33 and also provides protection for the motor 33.

[0081] In some embodiments, the housing 1 is provided with a bottom air inlet 161, which is located on the bottom side of the housing 1 and communicates with the lower cavity 13. For example, as Figure 7 and Figure 8 As shown, the housing 1 may include a bottom plate 16 located on the bottom side, and a bottom air inlet 161 may be provided on the bottom plate 16.
