[0052] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, and are used to explain the present application, and cannot be understood as a limitation of the present application.

[0053] The following description refers to the accompanying drawings. Figures 1-17 The air conditioner according to the embodiments of the present application is described.

[0054] The air conditioner according to the embodiments of the present application comprises a casing assembly 56, a heat exchanger assembly 55, an air duct assembly 51 and a deflector 30. The casing assembly 56 is formed with an air inlet 58 and an air outlet 1, the air outlet 1 extends in the up-down direction, and the heat exchanger assembly 55 and the air duct assembly 51 are arranged in the casing assembly 56.

[0055] When the air conditioner is working, air flows into the inside of the casing assembly 56 from the air inlet 58, exchanges heat with the heat exchanger assembly 55, and then enters the air duct assembly 51, and finally is guided by the air deflector 30 to blow out from the air outlet 1 to the indoor room to adjust the indoor temperature.

[0056] For example, the air duct assembly 51 can include an air duct volute 53 and a fan, the fan is installed on the air duct volute 53, and the fan is used to drive the flow of air. The fan includes a fan wheel 52 and a motor 54, the motor 54 is connected with the fan wheel 52 to drive the fan wheel 52 to rotate, thereby driving the flow of air.

[0057] For example, the heat exchanger assembly 55 can include a heat exchanger component 551 and an electric auxiliary heater 59, the heat exchanger component 551 includes a heat exchanger 552 and a heat exchanger support 553, the heat exchanger 552 is installed on the heat exchanger support 553, and the electric auxiliary heater 59 is installed on the heat exchanger support 553.

[0058] The air deflector 30 is rotatably connected with the casing assembly 56, and can open and close the air outlet 1. The rotation axis of the air deflector 30 extends in the up-down direction. A plurality of air diffusion holes 31 are formed on the air deflector 30 and penetrate the air deflector 30 in the thickness direction of the air deflector 30. The air conditioner has a normal air outlet mode and a windless mode. In the normal air outlet mode, the air deflector 30 opens the air outlet 1, and in the windless mode, the air deflector 30 closes the air outlet 1. By forming a plurality of air diffusion holes 31 on the air deflector 30 and penetrating the air deflector 30 in the thickness direction of the air deflector 30, when the air deflector 30 is in the closed state, air can be blown out from the plurality of air diffusion holes 31, realizing the windless effect and avoiding the discomfort caused by direct blowing.

[0059] With reference to Figure 10 The air deflector 30 includes a first air deflection part 32 and a second air deflection part 33, the first air deflection part 32 is located above the second air deflection part 33, and the arrangement density of the air diffusion holes 31 on the first air deflection part 32 is greater than that on the second air deflection part 33. The arrangement density of the air diffusion holes 31 is the area ratio of all air diffusion holes 31 per unit area of the air deflector 30. When the air conditioner is in the windless cooling state, cold air is more likely to sink. By making the arrangement density of the air diffusion holes 31 on the first air deflection part 32 located above greater than that on the second air deflection part 33 located below, the area of the upper region of the air outlet 1 of the air conditioner can be larger, and the air volume can be larger. When the air conditioner is in the windless cooling state, the cooling capacity of the air conditioner above is improved to compensate for the problem of insufficient cooling effect above the air conditioner due to the sinking of cold air; and the area of the lower region of the air outlet 1 can be smaller, so the air volume is smaller, and the air is more dispersed and soft, avoiding the direct blowing of cold air to the legs, and improving the comfort of the user.

[0060] For example, the two air outlets 1 can be formed on the casing assembly 56, and the two air outlets 1 are arranged in the left-right direction at intervals, and each air outlet 1 is provided with a corresponding air baffle 30.

[0061] For example, the casing assembly 56 can include a rear shell part 57 and a front shell part 561, the rear shell part 57 is connected to the rear side of the front shell part 561, the rear shell part 57 is formed with an air inlet 58, and the front shell part 561 can include a front shell 562 and an air outlet frame assembly 10, the air outlet frame assembly 10 is installed on the front shell 562, and the air duct assembly 51 can be located between the heat exchanger assembly 55 and the air outlet frame assembly 10. The air outlet frame assembly 10 is formed with an air outlet passage 15 and an air outlet 1, and the air baffle 30 is rotatably connected to the air outlet frame assembly 10. Further, the air outlet frame assembly 10 can include an air outlet frame 11 and a front panel 16, the air outlet frame 11 is formed with two air outlets 1, the two air outlets 1 are arranged in the left-right direction at intervals, and each air outlet 1 is provided with a corresponding air baffle 30, and the front panel 16 is connected to the front side of the air outlet frame 11 and located between the two air outlets 1.

[0062] The casing assembly 56 further includes a base 61 and a top cover 60, and the front shell part 561 and the rear shell part 57 are connected above the base 61, and the top cover 60 covers the top of the front shell part 561 and the rear shell part 57.

[0063] Alternatively, the air outlet frame 11 can include a front air outlet frame 12 and a rear air outlet frame 13, the front air outlet frame 12 is connected to the front side of the rear air outlet frame 13, the front air outlet frame 12 and the rear air outlet frame 13 are detachably connected, the air outlet 1 is formed on the front air outlet frame 12, and the rear air outlet frame 13 and the front air outlet frame 12 jointly define the air outlet passage 15.

[0064] For example, the air conditioner can further include a louver assembly 70, the louver assembly 70 is arranged in the air outlet passage 15 and installed on the air outlet frame 11, the louver assembly 70 includes a plurality of louver blades arranged in the up-down direction, and each louver blade can swing up and down.

[0065] For example, referring to Figure 9 and Figure 15 The air outlet frame assembly 10 is formed with a matching hole 14, and the air baffle 30 is provided with a matching part 20, the matching part 20 includes a matching shaft 22 extending in the first direction, the matching shaft 22 is arranged in the matching hole 14 and is rotatable relative to the matching hole 14. The matching part 20 is arranged in the first direction at intervals, and the matching hole 14 is also arranged at intervals. The matching hole 14 and the matching part 20 are one-to-one corresponding respectively. The matching part 20 and the air baffle 30 are detachably connected, and the matching part 20 and the air baffle 30 are clamped and connected.

[0066] For example, the fitting piece 20 comprises a connecting portion 21, a fitting shaft 22 is connected to one side of the connecting portion 21, the air deflector 30 is provided with a buckle 34, and the connecting portion 21 is provided with a clamping groove, and the buckle 34 is clamped into the clamping groove.

[0067] According to the air conditioner provided by the embodiment of the present application, the arrangement density of the air outlet holes 31 on the upper first air guiding portion 32 is greater than the arrangement density of the air outlet holes 31 on the lower second air guiding portion 33, so that the area of the upper air outlet 1 of the air conditioner is larger when the air conditioner is in the no-wind feeling cooling state, the cooling capacity of the air conditioner on the upper side is improved, and the problem of insufficient cooling effect on the upper side of the air conditioner due to the sinking of cold air is solved; and the area of the lower air outlet 1 of the air conditioner is smaller, so that the cold air is not directly blown to the legs, and the comfort of the user is improved.

[0068] According to some embodiments of the present application, referring to Figures 11-14 The arrangement density of the air outlet holes 31 on the first air guiding portion 32 gradually decreases in the direction from top to bottom. By gradually decreasing the arrangement density of the air outlet holes 31 on the first air guiding portion 32 in the direction from top to bottom, the air outlet area of the first air guiding portion 32 in the no-wind feeling state gradually decreases in the direction from top to bottom, so that the problem of insufficient cooling effect from bottom to top of the air conditioner due to the sinking of cold air is solved.

[0069] According to some embodiments of the present application, referring to Figures 11-14 The cross-sectional area of at least part of the air outlet holes 31 on the first air guiding portion 32 is greater than the cross-sectional area of the air outlet holes 31 on the second air guiding portion 33. By making the cross-sectional area of at least part of the air outlet holes 31 on the first air guiding portion 32 greater than the cross-sectional area of the air outlet holes 31 on the second air guiding portion 33, the opening of a single air outlet hole 31 on the first air guiding portion 32 is larger, and the arrangement mode of the air outlet holes 31 is simpler, so that the arrangement density of the air outlet holes 31 on the upper first air guiding portion 32 is greater than the arrangement density of the air outlet holes 31 on the lower second air guiding portion 33.

[0070] According to some embodiments of the present application, referring to Figures 11-14At least part of the air outlet holes 31 on the first air guide part 32 is formed as a waist-shaped hole, and at least part of the air outlet holes 31 on the second air guide part 33 is formed as a circular hole. By forming at least part of the air outlet holes 31 on the first air guide part 32 as a waist-shaped hole, the cross-sectional area of the air outlet holes 31 of the waist-shaped hole can be larger, the air outlet area is larger, the arrangement density of the air outlet holes 31 on the first air guide part 32 is increased, and the cooling capacity of the air conditioner above can be improved, so as to solve the problem of insufficient cooling effect of the air conditioner above due to the sinking of cold air. By forming at least part of the air outlet holes 31 on the second air guide part 33 as a circular hole, the air outlet area of the air outlet holes 31 of the second air guide part 33 is smaller than that of the waist-shaped hole on the first air guide part 32, the arrangement density of the air outlet holes 31 on the second air guide part 33 is reduced, the cold air directly blowing on the legs is avoided, and the comfort of the user is improved.

[0071] According to some embodiments of the present application, referring to Figures 11-14 The cross-sectional area of the plurality of air outlet holes 31 on the first air guide part 32 gradually decreases in the direction from top to bottom. By gradually decreasing the cross-sectional area of the plurality of air outlet holes 31 on the first air guide part 32 in the direction from top to bottom, the air outlet area of the first air guide part 32 in the windless state gradually decreases in the direction from top to bottom, so as to solve the problem of insufficient cooling effect of the air conditioner from bottom to top due to the sinking of cold air.

[0072] For example, the arrangement number and arrangement mode of the air outlet holes 31 of the first air guide part 32 and the second air guide part 33 of the air conditioner can be the same, so that the effect of gradually decreasing the air outlet area in the direction from top to bottom in the windless state can be achieved without changing the arrangement mode of the air outlet holes 31, and the design cost is reduced.

[0073] According to some embodiments of the present application, referring to Figures 11-14 The length dimension of the plurality of air outlet holes 31 on the first air guide part 32 in the up-down direction is hole length, and the hole length of the plurality of air outlet holes 31 on the first air guide part 32 gradually decreases in the direction from top to bottom. By gradually decreasing the hole length of the plurality of air outlet holes 31 on the first air guide part 32 in the direction from top to bottom, the air outlet area of the first air guide part 32 in the windless state gradually decreases in the direction from top to bottom, so as to solve the problem of insufficient cooling effect of the air conditioner from bottom to top due to the sinking of cold air.

By making the arrangement density of the air outlet holes 31 on the middle air guide area 35 greater than that of the lower air guide area 36 and less than that of the first air guide part 32, the air outlet area of the middle air guide area 35 can be greater than that of the lower air guide area 36, the cold air blown from the lower air guide area 36 can be avoided from directly blowing on the legs, the comfort of the user can be improved, and the air outlet amount of the middle air guide area 35 can be relatively greater than that of the lower air guide area 36.

[0075] According to some embodiments of the present application, referring to Figures 11-14 The cross-sectional area of the air outlet holes 31 of the middle air guide area 35 is the same as that of the lower air guide area 36. By making the cross-sectional area of the air outlet holes 31 of the middle air guide area 35 the same as that of the lower air guide area 36, the air outlet holes 31 of the second air guide part 33 can be more easily manufactured.

[0076] According to some embodiments of the present application, referring to Figures 11-14 The air outlet holes 31 of the middle air guide area 35 and the lower air guide area 36 are all circular holes. By making the air outlet holes 31 of the middle air guide area 35 and the lower air guide area 36 all circular holes, the air outlet holes 31 of the second air guide part 33 can be more easily manufactured.

[0077] According to some embodiments of the present application, referring to Figures 11-14 The lower air guide area 36 is further formed with decorative holes 37, the decorative holes 37 are blind holes or the lower air guide area 36 is provided with a blocking block to block the decorative holes 37. By making the decorative holes 37 blind holes or the lower air guide area 36 provided with a blocking block to block the decorative holes 37, the arrangement density of the air outlet holes 31 on the middle air guide area 35 can be greater than that of the lower air guide area 36 and less than that of the first air guide part 32 without changing the positions and arrangement of the decorative holes 37, the air outlet area of the middle air guide area 35 can be greater than that of the lower air guide area 36, the cold air blown from the lower air guide area 36 can be avoided from directly blowing on the legs, and the comfort of the user can be improved.

[0078] For example, the decorative holes 37 are uniformly arranged in the lower air guide area 36, and the air outlet holes 31 of the lower air guide area 36 are uniformly arranged in the lower air guide area 36, so that the air outlet of the overall area of the lower air guide area 36 is uniform, the air outlet amount of some positions is avoided from being too large and some positions not being air outlet, and the experience of the user is improved.

[0079] According to some embodiments of the present application, referring to Figures 11-14The total arrangement density of the air diffusing holes 31 and the decorative holes 37 of the lower air guiding area 36 is the same as the arrangement density of the air diffusing holes 31 of the middle air guiding area 35. By making the total arrangement density of the air diffusing holes 31 and the decorative holes 37 of the lower air guiding area 36 the same as the arrangement density of the air diffusing holes 31 of the middle air guiding area 35, the arrangement of the air diffusing holes 31 and the decorative holes 37 can be made more simple without changing the arrangement of the air diffusing holes 31 and the decorative holes 37, the air diffusing holes 31 and the decorative holes 37 of the second air guiding part 33 are easier to manufacture, and the upper air guiding area and the lower air guiding area 36 of the air conditioner can have higher consistency in appearance and be more beautiful.

[0080] According to some embodiments of the present application, referring to Figures 11-14 The total area of the air diffusing holes 31 on the lower air guiding area 36 is S1, the total area of the decorative holes 37 on the lower air guiding area 36 and the total area of the air diffusing holes 31 are S, and the ratio of S1 to S is 1 / 3-1 / 2. For example, the ratio of S1 to S can be 1 / 3, 2 / 5, 1 / 2, etc. By making the ratio of S1 to S not less than 1 / 3, the holes on the lower air guiding area 36 can be blocked more fully, the cold air blowing out of the lower air guiding area 36 can be more fully avoided from directly blowing on the legs, and the comfort of the user can be improved; by making the ratio of S1 to S not more than 1 / 2, the air volume of the lower air guiding area 36 can be sufficient, the air conditioner can have sufficient temperature adjusting capacity for the lower part, and the decorative holes 37 can not be too many and the air diffusing holes 31 can not be too few to cause the air conditioner to have insufficient temperature adjusting capacity for the lower part.

For example, the ratio of L1 to L can be 1 / 3, 1 / 4, 1 / 5, 1 / 6, etc. By making the ratio of L1 to L less than or equal to 1 / 3, the air volume of the air conditioner as a whole can be sufficient, the air conditioner can have sufficient temperature adjusting capacity, and the decorative holes 37 can not be too many and the air diffusing holes 31 can not be too few to cause the air conditioner to have insufficient temperature adjusting capacity.

[0082] According to some embodiments of the present application, referring to Figure 10 The two ends of the air guiding plate 30 in the width direction are side edge ends 38, the arrangement density of the air diffusing holes 31 on the side edge ends 38 is 0, and the width direction of the air guiding plate 30 is perpendicular to the up-down direction. In the related art, the air volume of the side edge ends 38 is large, and when the air conditioner is in the cooling mode, the side edge ends 38 are prone to form condensation, which is difficult to collect and discharge and is prone to drop on the ground. By making the arrangement density of the air diffusing holes 31 on the side edge ends 38 0, the air volume of the side edge ends 38 can be reduced, the temperature of the side edge ends 38 can be appropriately increased when the air conditioner is in the cooling mode, and the condensation formed on the side edge ends 38 can be reduced.

[0083] For example, the side end 38 includes a plurality of plug hole columns (for example, the plug hole columns can be three columns), and the plug hole columns are a plurality of decorative holes 37 uniformly spaced in the up-down direction, and the decorative holes 37 are arranged in the up-down direction of the air conditioner, and the plurality of plug hole columns are arranged in the left-right direction.

[0084] According to some embodiments of the present application, referring to Figure 7 and Figure 8 The shell assembly 56 includes a front shell part 561 and a rear shell part 57, the front shell part 561 is connected to the front side of the rear shell part 57, the air inlet 58 is formed on the rear shell part 57, the air outlet frame 11 is formed with an air outlet channel 15 and an air outlet 1, and the air deflector 30 is rotatably connected to the air outlet frame assembly 10. The bottom wall of the air outlet channel 15 is an air outlet bottom wall 41, and the air deflector 30 is located above the air outlet bottom wall 41.

[0085] When the air conditioner is working, the airflow enters the air conditioner from the air inlet 58 on the rear shell part 57, exchanges heat with the heat exchanger assembly 55, enters the air duct assembly 51, and finally is guided by the air deflector 30 to exit the air conditioner from the air outlet 1.

[0086] When the air deflector 30 is in a position closing the air outlet 1, referring to Figure 7 and Figure 8 The surface of the air deflector 30 facing outward of the shell assembly 56 is an outer side 39, and the lower end of the outer side 39 is formed into a flow guide surface 40, and the flow guide surface 40 is used to guide the condensed water on the outer side 39 downward to the air outlet bottom wall 41. By forming the lower end of the outer side 39 into the flow guide surface 40, when the condensed water on the outer side 39 gathers and flows downward, the flow guide surface 40 can guide the condensed water, so that the condensed water gathers and drips onto the air outlet bottom wall 41, facilitating the collection of the condensed water, avoiding the condensed water from dripping onto the ground, and improving the user experience.

[0087] According to some embodiments of the present application, referring to Figure 7 and Figure 8 When the air deflector 30 is in a position closing the air outlet 1, the projection of the flow guide surface 40 on the horizontal plane is located within the projection of the air outlet bottom wall 41 on the horizontal plane. By making the projection of the flow guide surface 40 on the horizontal plane be located within the projection of the air outlet bottom wall 41 on the horizontal plane when the air deflector 30 is in a position closing the air outlet 1, the flow guide surface 40 can more fully guide the condensed water and drip onto the air outlet bottom wall 41, avoiding the condensed water from dripping outside the air outlet bottom wall 41 and causing the condensed water to drip onto the ground, and improving the user experience.

[0088] According to some embodiments of the present application, referring to Figure 7 and Figure 8When the air deflector 30 is in the position of closing the air outlet 1, the guide surface 40 extends in the up-to-down direction towards the direction close to the inside of the shell assembly 56. By making the guide surface 40 extend in the up-to-down direction towards the direction close to the inside of the shell assembly 56, the guide surface 40 can guide the condensed water more fully, and when the condensed water flows from the outside to the inside along the inclined guide surface 40 under the action of its own gravity from the top to the bottom, the condensed water can be collected and dripped on the air outlet bottom wall 41.

[0089] According to some embodiments of the present application, referring to Figure 7 and Figure 8 , the guide surface 40 extends along an arc trajectory in the up-to-down direction. By making the guide surface 40 extend along an arc trajectory in the up-to-down direction, the corner of the guide surface 40 can be avoided to cut the hand of the relevant personnel when the air conditioner is carried; and the downward inclined surface of the guide surface 40 can also be made to transition naturally, and the guide surface 40 can guide the condensed water more fully, and the condensed water can flow downward along the arc guide surface 40, avoiding direct downward dripping of the condensed water.

[0090] According to some embodiments of the present application, referring to Figure 7 and Figure 8 , the front edge of the air outlet bottom wall 41 is formed with a water blocking protruding rib 42 protruding upward. By making the front edge of the air outlet bottom wall 41 formed with the water blocking protruding rib 42 protruding upward, when the condensed water drips on the air outlet bottom wall 41, the water blocking protruding rib 42 can block the condensed water, so that the condensed water is collected in the air outlet bottom wall 41, avoiding the condensed water flowing outward and dripping on the ground.

[0091] According to some embodiments of the present application, referring to Figure 7 and Figure 8 , when the air deflector 30 is in the position of closing the air outlet 1, the projection of the lower edge of the guide surface 40 on the horizontal plane is located on the side of the projection of the water blocking protruding rib 42 on the horizontal plane close to the inside of the shell assembly 56. By making the projection of the lower edge of the guide surface 40 on the horizontal plane located on the side of the projection of the water blocking protruding rib 42 on the horizontal plane close to the inside of the shell assembly 56, the guide surface 40 can more fully guide the condensed water, so that the condensed water drips on the air outlet bottom wall 41 and is fully blocked by the water blocking protruding rib 42, avoiding the condensed water dripping on the outside of the water blocking protruding rib 42 or the condensed water not being fully blocked by the water blocking protruding rib 42 causing the condensed water to drip on the ground, improving the user's experience.
