[0056] In order to solve the problem of complex structure and large volume of the air conditioner in the prior art, the present application provides an air conditioner.

[0057] Embodiment one

[0058] As Figures 1 to 11As shown, the air conditioner comprises a shell 10, a fan 20, an upper air deflector 30 and a lower air deflector 40, the shell 10 has an upper air duct 11 and a lower air duct 12; the fan 20 is one, the fan 20 is arranged in the shell 10; the upper air deflector 30 is arranged at the upper air outlet 111 of the upper air duct 11 in an openable and closable manner; the lower air deflector 40 is arranged at the lower air outlet 121 of the lower air duct 12 in an openable and closable manner, and the upper air deflector 30 and the lower air deflector 40 can be independently adjusted, so that the air conditioner has three operation modes of only upper air outlet, only lower air outlet and simultaneous upper and lower air outlet.

[0059] Since the fan 20 is arranged, the air in the air conditioner is blown to the upper air duct 11 and the lower air duct 12 under the action of the fan 20, and is output to the external environment through the upper air duct 11 and the lower air duct 12, so as to warm or cool the environment, in addition, the upper air deflector 30 and the lower air deflector 40 have the functions of guiding and draining, so that the blown air can be blown out at a certain angle, so as to achieve better air supply effect.

[0060] It should be noted that when the upper air deflector 30 is opened and the lower air deflector 40 is closed, the air in the air conditioner is blown out from the upper air outlet 111 of the upper air duct 11; when the upper air deflector 30 is closed and the lower air deflector 40 is opened, the air in the air conditioner is blown out from the lower air outlet 121 of the lower air duct 12; when the upper air deflector 30 and the lower air deflector 40 are opened at the same time, the air in the air conditioner is blown out from the upper air outlet 111 of the upper air duct 11 and the lower air outlet 121 of the lower air duct 12 at the same time.

[0061] In addition, when only the upper air outlet, the blown air is cold air relative to the external environment, the cold air moves forward along the top of the house and gradually sinks downward, realizing the bathing type cooling experience; when only the lower air outlet, the blown air is hot air relative to the external environment, the hot air moves forward along the ground and gradually rises upward, realizing the carpet type heating experience; when the upper and lower air outlets are blown at the same time, the blown air can be cold air or hot air, the cold air or hot air moves forward along the top of the house and the ground and gradually sinks downward or rises upward, maintaining a breeze or no wind feeling in the process of rising and falling, gradually changing the indoor temperature, and improving the comfort experience of people to the air conditioner.

[0062] As shown in Figures 1 to 7 The fan 20 is located at the intersection of the inlet of the upper air duct 11 and the inlet of the lower air duct 12 in the middle of the shell 10. Since the fan 20 is located at the intersection of the inlet of the upper air duct 11 and the inlet of the lower air duct 12, the shell 10 can divide the air to blow to the upper air duct 11 and the lower air duct 12 at the same time.

[0063] As shown in Figures 1 to 7As shown, the upper air duct 11 extends upwardly from the middle of the casing 10 to make the air outlet direction of the upper air outlet 111 of the upper air duct 11 tilt upwardly. In this way, the air of the upper air duct 11 can be blown upwardly obliquely, so as to be blown further while closely adhering to the roof wall surface, so as to increase the diffusion speed of the air and further increase the comfort experience of the user.

[0064] As shown, Figures 1 to 7 As shown, the lower air duct 12 extends downwardly from the middle of the casing 10 to make the air outlet direction of the lower air outlet 121 of the lower air duct 12 tilt downwardly vertically. In this way, the air of the lower air duct 12 can be blown to the ground and continuously diffused along the ground, effectively avoiding the air being blown directly to the person, so as to avoid the uncomfortable feeling of the human body.

[0065] As shown, Figures 1 to 7 As shown, the casing 10 comprises a bottom shell 13 and a front panel 14, and the side surface of the bottom shell 13 facing the front panel 14 serves as part of the air duct wall surface of the upper air duct 11 and part of the air duct wall surface of the lower air duct 12.

[0066] As shown, Figures 1 to 7 As shown, the upper air deflector 30 is pivotally connected with the bottom shell 13. Through the pivotal connection, the opening and closing of the upper air deflector 30 and / or the lower air deflector 40 can be realized to meet different working requirements, and at the same time, the connection mode of the pivotal connection is simple, easy to realize and convenient to operate.

[0067] As shown, Figure 2 As shown, the side edge of the upper air deflector 30 away from the front panel 14 is connected with the bottom shell 13, when the upper air deflector 30 is opened, the side of the upper air deflector 30 close to the front panel 14 is turned upwardly to open the upper air outlet 111 of the upper air duct 11, and after the upper air deflector 30 is turned to the position, the upper air deflector 30 extends obliquely upwardly toward the front panel 14. Due to the arrangement of the upper air deflector 30, when the upper air deflector 30 is opened, the air in the upper air duct 11 is blown out from the upper air outlet 111 and can be better blown forwardly under the guiding action of the upper air deflector 30, so as to increase the diffusion speed of the air and obtain the refrigeration air flow which adheres to the wall and slowly sinks, thereby making the refrigeration experience of the user better.

[0068] It should be noted that the streamline design of the upper air duct 11 can smoothly guide the air flow to turn and make it blow out from the upper air outlet 111 with a certain preferred inclination angle, and the blown air is guided by the upper air deflector 30 connected with the upper air duct 11 to blow to the ceiling of the room at a preferred angle.

[0069] As shown, Figure 2As shown, when the upper air deflector 30 is turned to the position, the extending direction of the upper air deflector 30 is consistent with the extending direction of the air duct wall surface of the upper air duct 11. In this way, the air of the upper air duct 11 can be better ensured to blow to the roof wall surface and continuously diffuse close to the wall surface to obtain the air flow of wall adhesion and slow sinking.

[0070] As shown in Figure 2 , the opening angle A of the upper air deflector 30 is between 30° and 60°. According to the actual needs of the user, the opening angle of the upper air deflector 30 can be appropriately changed to blow the air to a farther place, increase the diffusion speed of the air, and thus improve the use effect of the air conditioner and better meet the experience of the user.

[0071] As shown in Figures 1 to 7 , and Figure 10 , the air conditioner further comprises an upper volute tongue structure 50 and a lower volute tongue structure 60. The upper volute tongue structure 50 is arranged between the bottom shell 13 and the front panel 14, and one side of the upper volute tongue structure 50 facing the bottom shell 13 serves as another part of the air duct wall surface of the upper air duct 11. The lower volute tongue structure 60 is arranged between the bottom shell 13 and the front panel 14 and below the upper volute tongue structure 50. The upper volute tongue structure 50 and the lower volute tongue structure 60 are arranged in a spaced manner for avoiding the fan 20. One side of the lower volute tongue structure 60 facing the bottom shell 13 serves as another part of the air duct wall surface of the lower air duct 12. The upper volute tongue structure 50 and the bottom shell 13 jointly enclose the upper air duct 11, and the lower volute tongue structure 60 and the bottom shell 13 jointly enclose the lower air duct 12 to provide a passage for air output.

[0072] As shown in Figure 3 , the side edge of the lower air deflector 40 close to one side of the front panel 14 is pivotally connected with the lower volute tongue structure 60. When the lower air deflector 40 is opened, the side of the lower air deflector 40 away from the front panel 14 is flipped downward to open the lower air outlet 121 of the lower air duct 12, and after the lower air deflector 40 is turned to the position, the lower air deflector 40 extends vertically downward. Since the lower air deflector 40 extends vertically downward when it is opened, and the lower air deflector 40 can guide and flow the air blown out of the lower air outlet 121, the air can be blown to the ground and diffuse around along the ground, the temperature change is uniform, and the experience of the user is better. Through the pivotal connection, the opening and closing of the lower air deflector 40 can be realized to meet different working requirements. Meanwhile, the connection mode of the pivotal connection is simple, easy to realize, and convenient to operate.

[0073] As shown in Figure 8 , Figure 9As shown in the drawings, the diameter of the fan 20 is D, the first gap L1 is formed between the upper volute tongue structure 50 and the fan 20, the distance of the first gap L1 is greater than or equal to 0.0075*D and less than or equal to 0.0125*D; and / or the second gap L2 is formed between the lower volute tongue structure 60 and the fan 20, the distance of the second gap L2 is greater than or equal to 0.0075*D and less than or equal to 0.0125*D. In this way, the speed of the heat exchange air flow can be improved, and the performance of the air conditioner is better, which is more conducive to achieving rapid heating or cooling of the whole room.

[0074] As shown in the drawings, Figures 1 to 7 The air conditioner further comprises a heat exchanger 70, and the upper volute tongue structure 50 and / or the lower volute tongue structure 60 are provided with a support structure 61 on one side of the front panel 14, and the heat exchanger 70 is fixed in the shell 10 through the support structure 61. Since the support structure 61 is provided, the heat exchanger 70 can be fixedly installed.

[0075] As shown in the drawings, Figures 1 to 7 The support structure 61 comprises a support rib provided on the lower volute tongue structure 60, the bottom end of the heat exchanger 70 is supported on the support rib, and the top end of the heat exchanger 70 is fixed on the upper volute tongue structure 50 through a fastener. The support rib can well support the heat exchanger 70, and has a simple structure and is convenient to install. In addition, the structure is simple, the connection is convenient, and the reliability is high.

[0076] Preferably, the fastener is a screw.

[0077] As shown in the drawings, Figure 11 The support structure 61 has a notch 611 so that the condensed water formed in the heat exchanger 70 can flow out. Since the support structure 61 has the notch 611, the condensed water can flow out conveniently, and the structure is simple.

[0078] As shown in the drawings, Figure 11 The air conditioner further comprises a water collecting structure 80, and the water collecting structure 80 is communicated with the notch 611. Since the water collecting structure 80 is provided, the condensed water can be collected and discharged out of the air conditioner.

[0079] As shown in the drawings, Figure 11 The water collecting structure 80 has an inclined surface to discharge the condensed water. Since the water collecting structure 80 has the inclined surface, the condensed water can flow out conveniently, and the structure is simple and convenient to realize.

[0080] Preferably, the water collecting structure 80 is a water channel. The water channel can quickly discharge the condensed water, and has a simple structure and low cost.

[0081] As shown in the drawings, Figure 11As shown, the air conditioner further comprises a vertical plate 110, which is arranged at both ends of the upper volute tongue structure 50 and the lower volute tongue structure 60, and the side of the vertical plate 110 away from the upper volute tongue structure 50 and the lower volute tongue structure 60 is provided with a positioning flange 62.

[0082] As shown in the drawings, Figure 1 As shown, the air conditioner further comprises thermal insulation material, and the upper volute tongue structure 50 and / or the lower volute tongue structure 60 is provided with a containing cavity 51, and the thermal insulation material is arranged in the containing cavity 51. The thermal insulation material arranged in the containing cavity 51 can insulate the evaporator in the heat exchanger 70, so as to avoid the water vapor in the air around the evaporator from condensing into water on the surface of the upper volute tongue structure 50 and / or the lower volute tongue structure 60 when it is cooled.

[0083] Preferably, the thermal insulation material is foam. The foam has good thermal insulation effect, good waterproof property, and low cost.

[0084] Optionally, the heat exchanger 70 is at least one of an arc-shaped plate heat exchanger, a flat plate heat exchanger, or a multi-fold heat exchanger.

[0085] As shown in the drawings, Figure 1 Preferably, the heat exchanger 70 is a single-row or multi-row arc-shaped plate heat exchanger. The single-row arc-shaped plate heat exchanger can save internal space, and in actual production, the single-row arc-shaped plate heat exchanger has regular fin shape, and the punching die is simpler, thereby saving production procedures and reducing production cost.

[0086] As shown in the drawings, Figures 1 to 7 Preferably, the heat exchanger 70, the upper volute tongue structure 50, the lower volute tongue structure 60, and the fan 20 form a cavity structure. The outside air enters the air conditioner, is heated by the heat exchanger 70, and then enters the cavity structure. The fan 20 speeds up the air entering the cavity structure, so that the blown air has a higher flow rate and is blown to a farther place.

[0087] Preferably, the cavity structure is a convergent-divergent nozzle cavity 90. The convergent-divergent nozzle cavity 90 can increase the heat exchange efficiency, thereby improving the working efficiency of the air conditioner. In addition, after being heated by the heat exchanger 70, the air enters the convergent-divergent nozzle cavity 90, and the fan 20 speeds up the air entering the convergent-divergent nozzle cavity 90, so that the blown air has a higher flow rate and is blown to a farther place.

[0088] As shown in the drawings, Figure 11 Preferably, the upper volute tongue structure 50 and / or the lower volute tongue structure 60 is provided with the positioning flange 62 on the side edge facing the bottom shell 13, and the positioning flange 62 is lapped on the bottom shell 13. The positioning flange 62 is connected with the bottom shell 13, and the connection structure is simple, convenient, and fast.

[0089] As shown in the drawings, Figures 1 to 7As shown, the front panel 14 has an air inlet 130, and the air conditioner also includes a grille 100 disposed at the air inlet 130.

[0090] It should be noted that the grille 100 is used to protect the heat exchanger 70 and to enable the opening and closing of the air inlet 130.

[0091] like Figures 1 to 7 As shown, with the upper air duct 11 and the lower air duct 12 as the dividing line, the surface of the bottom shell 13 facing the front panel 14 bulges towards the fan 20 in the middle of the bottom shell 13, so that the inlets of the upper air duct 11 and the lower air duct 12 can be inhaled simultaneously. In this way, the air blown by the fan 20 can be split and enter the upper air duct 11 and the lower air duct 12 respectively, thereby improving the working efficiency of the air conditioner.

[0092] Alternatively, the air conditioner may be a wall-mounted or floor-standing air conditioner.

[0093] Example 2

[0094] The difference from Embodiment 1 is that the structure of the heat exchanger 70 is different.

[0095] like Figure 12 As shown, in this embodiment, the heat exchanger 70 is a multi-fold heat exchanger.

[0096] Example 3

[0097] The difference from Embodiment 1 is that the air conditioner draws air in from the side.

[0098] like Figure 13 As shown, the air conditioner also includes an exterior panel 120, which is spaced out on the front side of the front panel 14 to allow the air conditioner to draw air in from the side. Because the exterior panels 120 are spaced out on the front side of the front panel 14, the aesthetics of the air conditioner can be improved while still meeting the air intake requirements.

[0099] Example 4

[0100] The difference from Embodiment 1 is that the air conditioner draws air in from the side.

[0101] This embodiment is not illustrated. An air inlet 130 is formed at the connection between the bottom shell 13 and the front panel 14. The air conditioner also includes a grille 100, which is disposed at the air inlet 130 to allow the air conditioner to draw air in from the side.

[0102] Taking Example 1 as an example:

[0103] It should be noted that when refrigeration, heat exchange airflow is sucked from the air inlet 130 into the shell 10 by the fan 20, after heat exchange through the heat exchanger 70, the airflow flows through the convergent-divergent nozzle cavity 90 formed by the upper volute tongue mechanism and the lower volute tongue structure 60, under the action of the fan 20, the flow rate of the airflow is increased and blown to the upper air duct 11 and the lower air duct 12. Since the lower air outlet 121 of the lower air duct 12 is closed, the airflow in the lower air duct 12 cannot be blown out through the lower air outlet 121, and a high pressure area P is formed inside the lower air duct 12. The airflow in the high pressure area P rotates due to the pressure, and the upward rotating airflow is again taken away by the rotating fan 20. Finally, the high pressure area P will force all the heat-exchanged air to move outward through the upper air duct 11. The upper air duct 11 is a streamlined air duct designed according to the airflow properties after refrigeration and refrigeration comfort design theory. It can smoothly guide the airflow to change direction and make it have a certain preferred inclination angle to blow out from the upper air outlet 111. The blown airflow is guided by the upper air deflector 30 connected to the upper air duct 11 to blow onto the room ceiling at a preferred angle. At this time, due to the wall sticking motion property of fluid, that is, the conda effect, the fluid in motion flows forward along the solid wall. The cold airflow after refrigeration has a higher density than the hot air in the room as a whole. While moving forward along the ceiling, the cold airflow is affected by gravity and slowly sinks.

[0104] When heating, the heat exchange airflow is sucked from the air inlet 130 into the shell 10 by the fan 20, after heat exchange through the heat exchanger 70, the airflow flows through the convergent-divergent nozzle cavity 90 formed by the upper volute tongue mechanism and the lower volute tongue structure 60, under the action of the fan 20, the flow rate of the airflow is increased and blown to the upper air duct 11 and the lower air duct 12. Since the lower air outlet 121 of the lower air duct 12 is closed, the airflow in the lower air duct 12 cannot be blown out through the lower air outlet 121, and a high pressure area P is formed inside the lower air duct 12. The airflow in the high pressure area P rotates due to the pressure, and the upward rotating airflow is again taken away by the rotating fan 20. Finally, the high pressure area P will force all the heat-exchanged air to move outward through the upper air duct 11. The upper air duct 11 is a streamlined air duct designed according to the airflow properties after refrigeration and refrigeration comfort design theory. It can smoothly guide the airflow to change direction and make it have a certain preferred inclination angle to blow out from the upper air outlet 111. The blown airflow is guided by the upper air deflector 30 connected to the upper air duct 11 to blow onto the room ceiling at a preferred angle. At this time, due to the wall sticking motion property of fluid, that is, the conda effect, the fluid in motion flows forward along the solid wall. The cold airflow after refrigeration has a higher density than the hot air in the room as a whole. While moving forward along the ceiling, the cold airflow is affected by gravity and slowly sinks.

[0105] When the air conditioner is in fast cooling or heating mode, the streamlined design of the upper air duct 11 can smoothly guide the air flow to turn and have a preferred inclination angle to blow out from the upper air outlet 111, and the air flow is guided by the upper air deflector 30 connected to the upper air duct 11 to blow to the top of the room at a preferred angle; at this time, the streamlined design of the lower air duct 12 makes the lower air outlet 121 close to the wall and the extension line is tangent to the vertical direction, which can guide the air flow after heating to blow out smoothly along the vertical direction, and the outer opening of the air deflector limits the air flow to blow to the front of the air conditioner, further guiding the air flow to blow vertically downward, preventing people from feeling uncomfortable.
