The invention provides a cabinet air conditioner.

Referring to fig. 1, 2 and 3, the cabinet air conditioner includes a main body 10, and the main body 10 may be disposed in a square shape or a cylindrical shape. The housing 11 of the main body 10 is generally composed of a top plate 111, a bottom plate 112, and a wall plate 113 located between the top plate 111 and the bottom plate 112, wherein the wall plate 113 has a front panel 113a facing forward, a back panel 113b opposite to the front panel 113a, and a side wall connecting the front panel 113a and the back panel 113b, and herein, the front panel 113a, the back panel 113b, and the wall plate 113 may be integrally formed or may be separately provided. The main body 10 is internally provided with a heat exchanger 40 and a fan 30, the wall plate 113 is provided with an air inlet for external air to enter, and after the air enters the main body 10 from the air inlet and exchanges heat with the heat exchanger 40, the fan 30 blows airflow upwards and blows the airflow out from the air outlet.

In the embodiment of the present invention, as shown in fig. 1, the cabinet air conditioner includes a main body 10 extending in an up-down direction, an air duct inner cavity is formed in the main body 10, the main body 10 includes a top plate 111, a wall plate 113 and an air guiding device 14, and a first air outlet 12 communicated with the air duct inner cavity is opened on the top plate 111. The wall plate 113 extends in the vertical direction, the upper end of the wall plate 113 is connected with the top plate 111, the wall plate 113 comprises a front panel 113a, and two second air outlets 13 which extend in the vertical direction and are communicated with the air duct inner cavity are formed in the front panel 113 a. The two second outlets 13 are respectively and correspondingly located at the left and right sides of the front panel 113 a. The air guiding device 14 is installed at the first air outlet 12, the air guiding device 14 includes a damper 14a for guiding the air flow blown out from the first air outlet 12 to the front, and the damper 14a is rotatably connected to the top plate 111.

Referring to fig. 3, an air outlet frame 20 (see fig. 9) is generally disposed in the inner cavity of the air duct, and an opening 210 is disposed on the upper cover plate 21 of the air outlet frame 20. When the fan 30 is operated, the airflow flows upward to the air outlet frame 20 after passing through the heat exchanger 40 for heat exchange, and the airflow entering the air outlet frame 20 directly blows out from the first air outlet 12 through the opening 210 on one hand and flows out from the second air outlet 13 on the other hand. Because the fan 30 drives the airflow in an upward direction, after the airflow enters the air outlet frame 20, the airflow is directly blown out from the first air outlet 12, so that the flowing resistance of the airflow can be greatly reduced (in the prior art, the blowing angle of the airflow is changed by 90 degrees by blocking the airflow through the air outlet frame 20, that is, the vertical and upward airflow is changed into the horizontal blown airflow), and thus, the refrigeration effect is better. In addition, because the velocity of flow of air current in vertical direction is very fast, the atmospheric pressure of wind channel inner chamber is higher relatively, consequently, some air current can flow slowly from the second air outlet. It should be noted that the air outlet frame 20 may not be disposed in the inner cavity of the air duct, and in this case, when the fan 30 operates, the air flows upward to the first air outlet 12 and the second air outlet 13 after passing through the heat exchanger 40 for heat exchange.

The cabinet air conditioners are generally placed against a wall or in a corner of a wall. The front of the cabinet air conditioner is generally the activity area of the user, and the airflow flows to the front and the upper part after being blown out from the first air outlet 12, so that the airflow in the area which is positioned in front of the cabinet air conditioner and far away from the cabinet air conditioner can be quickly convected in the vertical direction. The air flow speed blown out from the two second air outlets 13 is slow, and the air flow cannot blow a user directly, but due to the existence of the second air outlets 13, the positions near the two second air outlets 13 become a cold source, and the air in the lower half indoor part can also be in convection with the cold air near the second air outlets, so that heat exchange occurs. Therefore, under the combined action of the first air outlet 12 and the second air outlet 13, the cabinet air conditioner cannot directly blow a user, and after the cabinet air conditioner operates, indoor airflow can be convected vertically and horizontally, so that the convection effect is better, heat exchange is quicker, and wind feeling is soft.

Here, when the first outlet 12 is opened largely, the second outlet 13 flows out less air, which is disadvantageous to the convection of the horizontal air flow. By turning the damper 14a, on one hand, the air outlet area of the first outlet 12 can be adjusted, so that the user can adjust the ratio of the air flow blown out from the first outlet 12 to the air flow blown out from the second outlet 13, thereby improving the indoor air flow convection effect. On the other hand, by turning the damper 14a, the airflow can be directed at different angles, and the area in which the airflow blown out from the first outlet 12 can flow is wide.

For example, when the damper 14a is fully opened, the amount of airflow blown out from the first outlet 12 accounts for 80% of the total amount, and the amount of airflow blown out from the second outlet accounts for 20% of the total amount; by turning over the left and right dampers 14a, the effective area of the first outlet 12 is half of the original area, the air output thereof becomes 60%, and the total amount of the airflow blown out from the second outlet accounts for 40%. Therefore, the horizontal air flow convection effect and the vertical air flow convection effect can be adjusted, and the indoor air flow convection can be more uniform.

According to the technical scheme, the first air outlet 12 is formed in the top plate 111 of the cabinet air conditioner, the air guide device 14 is arranged at the first air outlet 12, and the two second air outlets 13 are formed in the wall plate 113 of the cabinet air conditioner, so that most of air flow can be blown to the front and the upper part of the panel 113a from the first air outlet 12 by adjusting the air door 14a of the air guide device 14; the remaining small part air current is blown out by second air outlet 13, and the air current velocity of flow that flows out from second air outlet 13 is slower, can not directly blow the user, and indoor air current not only can be in the upper and lower convection current in addition, can also be in the level to the convection current effect preferred, the heat exchange is very fast, and is more even, and the wind-force is more soft.

Referring to fig. 4, in order to enable the damper 14a to guide the airflow to a wider area, in this embodiment, the damper 14a includes a first damper 141 and a second damper 142 arranged in a front-rear direction, and a first motor 14b and a second motor 14c installed inside the top plate 111. The first motor 14b is connected with the first air door 141, the second motor 14c is connected with the second air door 142, and the electric control board of the cabinet air conditioner independently controls the first motor 14b and the second motor 14 c. In this manner, the user can control the angle of the first damper 141 and the second damper 142, respectively, via a remote control or control buttons on the panel 113a to direct the airflow to a wider area. For example, the first motor 14b is controlled to rotate, the first damper 141 is controlled to form an angle of 30 ° with the horizontal direction, the second motor 14c is controlled to rotate, and the second damper 142 is controlled to form an angle of 60 ° with the horizontal direction, so that the first damper 141 mainly guides the airflow to the area away from the front panel 113a of the cabinet air conditioner. The second damper 142 primarily directs the airflow upward in the room so that the airflow quickly fills the upper portion of the room to facilitate convection of the entire indoor air upward and downward.

In an embodiment, with continued reference to fig. 1 to 3, in order to direct the airflow blown out from the second air outlet 13 to a wider range to improve the indoor airflow convection to be more balanced and uniform, an air guiding plate 15 extending in the vertical direction is disposed at each second air outlet 13, and an upper end and/or a lower end of the air guiding plate 15 is rotatably connected to the wall plate 113 to be capable of being turned back and forth. Here, in order to automatically control the turning of the air deflector 15, a driving motor may be installed on the inner wall of the wall 113, and the driving motor is connected to the upper end or the lower end of the air deflector 15, so as to drive the air deflector 15 to turn inside the second outlet 13.

Referring to fig. 5, the airflow is directed forward and upward by the damper 14 a. In order to make the blowing angle of the air flow wider and have a wider range, in the present embodiment, the air guiding device 14 further includes a plurality of air guiding blades 14d and a driving device 14e disposed inside the top plate 111. The guide vanes 14d extend in the left-right direction and are arranged at intervals in the front-back direction, and the driving device 14e is used for driving the guide vanes 14d to swing in the front-back direction. Therefore, under the combined action of the air guide blades 14d and the air door 14a, the flow direction range of the air flow is wider, and the convection of indoor air is facilitated.

On the basis of the previous embodiment, referring to fig. 5 and 6, the driving device 14e includes a third motor 143 and a connecting rod 144, the connecting rod 144 is movably connected to the plurality of air guide blades 14d, the third motor 143 is connected to one of the air guide blades 14d, and the connecting rod 144 drives the other air guide blades 14d to swing. Here, the connecting rod 144 is movably connected to the plurality of air guiding vanes 14d, because when the third motor 143 drives one of the air guiding vanes 14d to swing, the air guiding vane 14d drives the connecting rod 144 to move, and the connecting rod 144 also needs to drive the other air guiding vanes 14d to swing while moving. For example, a shaft 145 is disposed at a lower end of each of the air guiding vanes 14d, a shaft groove 146 for accommodating the shaft 145 is disposed on the connecting rod 144, and the shaft 145 is sleeved on the shaft 145 through the shaft groove 146. When the third motor 143 rotates, the air guiding blade 14d connected to the third motor 143 swings to drive the connecting rod 144 to move, and at this time, the connecting rod 144 has a pulling effect on other air guiding blades 14d while moving. Since the connecting rod 144 is engaged with the shaft 145 of the other fan 14d through the shaft groove 146, the other fan 14d can follow the movement and rotate relative to the connecting rod 144.

Referring to fig. 7, when the airflow blows the damper 14a, the airflow is blocked by the damper 14a, on one hand, the wind is damaged, and on the other hand, the impact of the airflow on the damper 14a also generates noise. In this embodiment, the air doors 14a are respectively provided with a plurality of air outlets 140. In this manner, the effective area of the damper 14a for blocking the airflow is reduced, the wind resistance can be greatly reduced, and the noise generated by the airflow impacting the damper 14a is correspondingly reduced.

In addition, when the airflow blows towards the damper 14a, the outer surface of the damper 14a (the damper 14a has an inner surface and an outer surface, when the damper 14a closes the first air outlet 12, the inner surface faces downward, and the outer surface faces upward) may generate condensed water, and if not processed, the condensed water may flow into the inner cavity of the air duct, and then is blown out from the first air outlet 12, which is disadvantageous to the user. Due to the existence of the air outlet hole 140, the air is blocked by the air door 14a, the direction of one part of the air flow is changed (for example, the included angle is 45 degrees with the horizontal direction), and the other part of the air flow passes through the air outlet hole 140, so that the air temperature of the outer surface of the air door 14a is low, and no condensed water is generated on the outer surface of the air door 14 a.

In addition, due to the existence of the air outlet hole 140, after the airflow blown out from the first air outlet 12 passes through the air door 14a, a part of the airflow passes through the air outlet hole 140 to flow, and a part of the airflow forms a certain included angle with the vertical direction to be blown out, so that the blowing angle of the airflow is wider, and the convection and heat exchange of the indoor airflow are more uniform.

On the basis of the above embodiment, referring to fig. 7 and 8, it is considered that after the air flow passes through the air outlet 140, if the air flow velocity is relatively fast, the ambient air will rapidly flow to the outer surface of the damper 14a, and the temperature of the upper surface is not cooled, and the condensed water is formed. In this embodiment, in order to further prevent the formation of condensed water on the upper surface of the damper 14a, the aperture of the air outlet 140 is gradually enlarged from the lower portion to the upper portion. Due to the divergent arrangement of the air outlet 140, even if the flow rate of the air flow entering the air outlet 140 is large, the flow rate of the air flow flowing out of the air outlet 140 is rapidly reduced, so that the air flow can rapidly cover the outer surface of the air door 14a, the temperature of the outer surface is rapidly cooled, and condensed water is not easily formed.

In a preferred embodiment, referring to fig. 9 and 10, an air outlet frame 20 is disposed in the air duct cavity, an opening 210 facing the first air outlet 12 is disposed on an upper cover plate 21 of the air outlet frame 20, and a plurality of first air holes 211 disposed around the opening 210 are further disposed on the upper cover plate 21. Here, considering that the upper cover 21 corresponding to the periphery of the opening 210 has a large resistance to the air flow, the noise generated when the air flow is blown upward is large. With the first ventilation holes 211 provided, the resistance of the upper cover plate 21 to the air flow is reduced, and the noise generated by the air flow impacting the damper 14a is also reduced accordingly.

Referring to fig. 11, in another preferred embodiment, considering that a part of the air flow cannot be directly blown out from the first outlet 12 after the air flow is blown out from the first vent 211, a vortex is formed between the upper cover plate 21 and the top plate 111, thereby generating noise. To solve this problem, in this embodiment, the top plate 111 further has a plurality of second ventilation holes 1111 located at the periphery of the opening 210. So, on the one hand, the setting of first bleeder vent 211 and second bleeder vent 1111, but greatly reduced air loss improves cabinet air conditioner's efficiency. On the other hand, the noise generated in the main body 10 is blocked by the upper cover 21 and the top plate 111, and the noise emitted from the main body 10 is low.

A first cavity 1110 is formed between the upper cover plate 21 and the top plate 111, noise generated in the inner cavity of the air duct is partially absorbed after passing through the upper cover plate 21, and the noise is further reduced after entering the first cavity 1110 through the first ventilation holes 211 and being absorbed by each side wall of the first cavity 1110, so that the noise finally emitted from the second ventilation holes 1111 is relatively small. In order to make the noise reduction effect of the upper cover plate 21 and the top plate 111 better, the first air vent 211 and the second air vent 1111 are staggered (staggered in the direction of the upper cover plate 21 towards the top plate 111) so as to avoid the noise from directly coming out from the second air vent 1111 after the air outlet frame 20 enters the first cavity 1110, thereby making the noise reduction effect better.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
