The invention provides a cabinet air conditioner.

Referring to fig. 1 and 2, 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 side panel 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, referring to fig. 3, the cabinet air conditioner includes a main body 10 extending in an up-down direction, and an air duct inner cavity is formed in the main body 10. The main body 10 comprises a top plate 111, a grille 15 and a wall plate 113 extending in the vertical direction, the top plate 111 is provided with a first air outlet 12 communicated with the inner cavity of the air duct, and the grille 15 is mounted at the first air outlet 12; the upper end of the wall plate 113 is connected to the top plate 111, and the wall plate 113 is provided with an air outlet area 13 for the airflow in the inner cavity of the air duct to flow out.

An air outlet frame 20 (refer to fig. 2 and 9) is generally disposed in the inner cavity of the air duct, and an opening 210 is disposed on an upper cover plate 21 of the air outlet frame 20. When the fan 30 is operated, the air flows upward to the air outlet frame 20 after passing through the heat exchanger 40 for heat exchange. The airflow entering the air-out frame 20 is directly blown out from the first air outlet 12 through the opening 210, and flows out from the air-out area 13. 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 flow velocity of the air flow in the vertical direction is relatively fast, the air pressure in the inner cavity of the air duct is relatively high, and therefore, a part of the air flow can slowly flow out of the air outlet area 13.

The air flow blown out from the first outlet 12 is blown out upward to rapidly cool the air in the upper half of the room, and the air in the lower half of the room flows upward to form a circular flow, so that the air in the upper half of the room exchanges heat with the air in the lower half of the room. In addition, the air flow flowing out of the air outlet area 13 has a low flow rate and does not blow directly to the user, but due to the existence of the air outlet area 13, the air near the air outlet area 13 becomes a cold source, and the air in the lower half of the room is also in convection with the cold air near the air outlet area 13 to generate heat exchange. Therefore, under the combined action of the first air outlet 12 and the air outlet area 13, the cabinet air conditioner cannot be directly blown to a user, and after the cabinet air conditioner runs, indoor airflow can be convected vertically and horizontally, so that the convection effect is better, heat exchange is quicker and more uniform, and the wind sensation is softer. It should be noted that the air outlet region 13 may be the upper half of the wall plate that is open forward. In order to make the area that the air current that blows out in the opening can flow to wider, can set up wind-guiding frame in the opening.

In addition, as the opening 210 of the first air outlet 12 faces upwards, the impurities are easy to fall into the air duct inner cavity from the first air outlet 12, and the fan 30 is arranged in the air duct inner cavity, once a foreign object (such as a mobile phone, a water cup or other objects) is transferred into the air duct inner cavity from the first air outlet 12, the cabinet air conditioner will be damaged, and even a safety accident will occur in a serious case. After the grid 15 is arranged, foreign objects can be effectively prevented from being transferred into the inner cavity of the air duct, so that the cabinet air conditioner is protected, and safety accidents can be avoided.

According to the technical scheme, the first air outlet 12 is formed in the top plate 111 of the cabinet air conditioner, the air outlet area 13 is formed in the wall plate 113 of the cabinet air conditioner, so that most of air flow can be blown upwards from the first air outlet 12, the rest of air flow is blown out from the air outlet area 13, the flow rate of the air flow flowing out of the air outlet area 13 is low, and the air flow cannot blow a user directly, and in addition, indoor air flow can be convected not only in the vertical direction but also in the horizontal direction, so that the convection effect is good, the heat exchange is fast and uniform, and the wind feeling is soft.

Referring to fig. 3, 4 and 6, in order to make the convection of the indoor air in the horizontal direction and the vertical direction adjustable, in an embodiment, a damper 14a for opening or closing the first outlet 12 is provided at the first outlet 12. The user can adjust the effective air outlet area damper 14a of the first air outlet 12 through the damper 14 a. When the first outlet 12 is fully opened, the air flow from the outlet area 13 is less, which is unfavorable for the convection of the horizontal air flow. By adding the damper 14a, the air outlet area of the first air outlet 12 is adjustable, and then the user can adjust the ratio of the air flow blown out from the first air outlet 12 to the air flow blown out from the air outlet area 13, so that the indoor air flow convection effect is better. For example, when the damper 14a is fully opened, the amount of airflow blown out from the first outlet 12 accounts for 85% of the total amount, and the amount of airflow blown out from the outlet region 13 accounts for 15% of the total amount; by adjusting the damper 14a, the effective area of the first outlet 12 is half of the original maximum area, the air output thereof becomes 65%, and the total amount of the airflow blown out from the air outlet region 13 accounts for 35%. 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.

With continued reference to fig. 3 and 4, in order to facilitate the turning of the damper 14a, in this embodiment, the air guiding mechanism 14 further includes a connecting rod 14c and a motor 14b, the motor 14b is installed below the top plate 111, one end of the connecting rod 14c passes through the grille 15 and is connected to the damper 14a, and the other end is connected to the motor 14 b. The motor 14b drives the damper 14a to rotate through the connecting rod 14c, so as to open or close the first air outlet 12. When the motor 14b rotates the link 14c, the link 14c can rotate the damper 14a to adjust an included angle of the damper 14a relative to the horizontal direction, so as to direct the airflow blown out from the first outlet 12 to different angles.

Referring to fig. 3 and 4, in the above embodiment, the link 14c may be straight or curved. Considering that the straight link 14c is not advantageous for mounting the damper 14a, the link 14c is herein provided in an arc shape convex outward in a direction away from the damper 14 a. For example, the link 14C is arranged in a C-shape or U-shape, one end of the U-shaped link 14C is connected to the damper 14a, and the other end of the U-shaped link 14C is connected to the motor 14b, so that when the motor 14b rotates, the U-shaped link 14C drives the damper 14a to turn.

Referring to fig. 7, in order to improve the air flow convection effect in the horizontal direction, in an embodiment, the air outlet region 13 includes a plurality of first through holes 13a disposed on the wall plate 113 and arranged at intervals in the circumferential direction of the main body 10. After a plurality of first through holes 13a are arranged, air from the air outlet area 13 can be diffused along the circumferential direction of the cabinet air conditioner, so that air flow in all directions of the cabinet air conditioner can be convected with cold air in the air outlet area 13, and indoor air heat exchange is more uniform. In addition, because the plurality of first through holes 13a are arranged at intervals along the circumferential direction of the main body 10, the airflow blown out by the first through holes 13a in all directions is softer under the dispersion action of the first through holes 13a in multiple directions on the air pressure in the air duct inner cavity.

Referring to fig. 8, when the air flow blows toward the damper 14a, the air flow is blocked by the damper 14a, which may cause wind damage, and noise due to the impact of the air flow on the damper 14 a. In this embodiment, the damper 14a is provided with a plurality of second through holes 141. In this way, the effective area of the damper 14a that blocks 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 air door 14a, condensed water is generated on the back surface of the air door 14a, and if the condensed water is not processed, the condensed water flows into the inner cavity of the air duct and is blown out from the first air outlet 12, so that disadvantages are caused to users. Due to the existence of the second through hole 141, the air is blocked by the air door 14a, a part of the air flow changes direction (for example, forms an angle of 45 degrees or 60 degrees with the horizontal direction), and the other part of the air flow passes through the second through hole 141, so that the air temperature on the back of the air door 14a is low, and no condensed water is generated on the back of the air door 14 a.

In addition, due to the existence of the second through hole 141, after the airflow blown out from the first air outlet 12 passes through the damper 14a, a part of the airflow continues to flow upwards, and a part of the airflow is blown out at a certain included angle with the vertical direction, so that the blowing angle of the airflow is wider, and the convection and heat exchange of the indoor airflow are more uniform.

Referring to fig. 5, the grid 15 is composed of a plurality of partitions, which may be arranged in parallel, staggered, or staggered in the transverse and longitudinal directions. Considering that the plurality of partition plates generate resistance to the airflow when the airflow is blown out from the first outlet 12, in this embodiment, a third through hole 151 is formed through each partition plate in the vertical direction, so that the airflow resistance is greatly reduced when the airflow passes through the grille 15. In addition, the third through holes 151 formed in the partition plate can absorb noise generated by vortex in the inner cavity of the air duct.

Referring to fig. 9, an air outlet frame 20 is generally disposed in an inner cavity of the air duct, in this embodiment, 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 located on the periphery of 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.

In addition to the above embodiment, referring to fig. 10, after the airflow is blown out from the first ventilation hole 211, a part of the airflow cannot be directly blown out from the first outlet 12, and therefore, a vortex is formed between the upper cover plate 21 and the top plate 111, which may generate 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 first 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.

Referring to fig. 11, a first cavity 1110 is formed between the upper cover plate 21 and the top plate 111, noise generated in the duct inner chamber is partially absorbed by the upper cover plate 21, and the noise is further reduced by the absorption of each side wall of the first cavity 1110 after entering the first cavity 1110 through the first ventilation hole 211, so that the noise finally emitted from the second ventilation hole 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.

In addition, referring to fig. 12, the first vent hole 211 has two ports, one of which is an outer port close to the top plate 111, and the other of which is an inner port opposite to the outer port, and in order to make the upper cover plate 21 have a better noise absorption effect, in this embodiment, the inner port of the first vent hole 211 is tapered from bottom to top. Similarly, the second ventilation hole 1111 also has two ports, and in order to make the noise absorption effect of the top plate 111 better, the inner port of the second ventilation hole 1111 is gradually reduced from bottom to top.

Although the noise can enter the air outlet frame 20 and the first cavity 1110 in sequence. The noise is reduced in the first stage through the air outlet frame 20, and then part of the noise is filtered out and the other part is filteredThe component noise is filtered by the first cavity 1110. Here, it is considered that the too large aperture of the first vent 211 may cause the poor vibration effect of the air molecules in the first cavity 1110, and the poor noise reduction effect. To this end, in one embodiment, the aperture d of the first vent 211 is₁Greater than 0 mm and less than or equal to 3 mm. In addition, if the aperture of the first vent hole 211 is too small, the air flow is difficult to pass through, so that the aperture of the first vent hole 211 is preferably 1.5mm to 2.5 mm. Similarly, the aperture d of the second venting hole 1111₂Not too large, the aperture d of the second air hole 1111₂Greater than 0 and less than or equal to 2 mm; of course d₂Too small, the aperture d of the second ventilation hole 1111 is not easily decreased₂In the range of 1mm to 1.5mm is the preferred embodiment. The aperture d of the first vent hole 211 is defined as₁Is larger than the aperture d of the second ventilation hole 1111₂. This is because the remaining noise is relatively small after being filtered by the upper cover plate 21 of the outlet frame 20, and the aperture d of the second venting hole 1111 is small₂It is not necessary to make the size larger, but rather the vibration effect of the air in the first cavity 1110 is affected.

Referring to fig. 10 and 13, considering that the cabinet air conditioner is generally placed near a wall or a corner, if the air flowing out of the air outlet area 13 blows strongly, the efficiency of the cabinet air conditioner will be reduced. In one embodiment, in order to make the air blown out from the air outlet area 13 mainly flow out of the panel 113a, so as to cool and soften the wind in front of the panel 113a, the air outlet area 13 includes a plurality of first air outlet holes 131 disposed on the panel 113 a. Because the amount of the airflow in the inner cavity of the air duct blown out from the panel 113a is small, and the panel 113a is provided with a plurality of first air outlet holes 131, the airflow is blown out from the first air outlet holes 131 more softly. Moreover, the panel 113a with the first air outlet 131 has an absorption effect on noise generated by air flow in the air duct inner cavity, so that the purpose of noise reduction can be achieved.

Similarly, in the embodiment, in order to further reduce the noise of the airflow, in the present embodiment, the sidewall 22 of the air-out frame 20 is opened with a plurality of second air-out holes 221 facing the air-out area 13. Thus, the noise generated in the main body 10 is blocked by the air-out frame 20 and the front panel 113a, and the noise emitted from the front panel 113a is finally low.

Referring to fig. 13, a second cavity 130 is formed between the air-out frame 20 and the front panel 113a, and noise generated in the air duct cavity is absorbed by the air-out frame 20, so that the noise is reduced. And then enters the second cavity 130 through the first air outlet 131, and is absorbed by each side wall of the second cavity 130, so that the noise is further reduced. So that the noise finally emitted from the first air outlet 131 is relatively small. In order to make the noise reduction effect of air-out frame 20 and front panel 113a is better, first exhaust vent 131 with second exhaust vent 221 is the setting of staggering (stagger to the front in the back) to avoid the noise directly to get into directly spread by first exhaust vent 131 after second cavity 130 by air-out frame 20, and then make 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.
