The invention provides a cabinet air conditioner.

Referring to fig. 1 to 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 formed of a top plate 111, a bottom plate 112, and a wall plate 113 between the top plate 111 and the bottom plate 112, wherein the wall plate 113 has a front face 113a facing forward, a back face 113b opposite to the front face 113a, and side walls connecting the front face 113a and the back face 113 b. Here, the front plate 113a, the back plate 113b, and the wall plate 113 may be integrally formed, or may be provided separately. 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, and 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 extending in the vertical direction, and an air door 14, wherein the top plate 111 is provided with a first air outlet 12 communicated with the inner cavity of the air duct. 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. The damper 14 is slidably mounted on the top plate 111 to open or close the first outlet 12.

Specifically, an air outlet frame 20 (see fig. 2, 7 and 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 air outlet area 13 on the other hand. Because the driving direction of the fan 30 to the airflow is upward, 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, and 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.

When the cabinet air conditioner is operated, the damper 14 is opened, the air flow blown out from the first air outlet 12 blows 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, so that the air in the room forms a circular flow, and 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 directly blow 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 wind is soft. 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 grid in the opening.

Here, when the first outlet 12 is fully opened, the air flow from the outlet area 13 is low, which is disadvantageous for the convection of the horizontal air flow. By sliding the position of the damper 14, the air outlet area of the first outlet 12 is adjusted, and then 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 air outlet area 13, so as to make the indoor air flow convection effect better. For example, when the damper 14 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 sliding the damper 14, the effective area of the first outlet 12 is half of the original maximum area, the air output is 60%, and the total amount of the airflow blown out from the air output area 13 is 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, a first air outlet 12 is formed in a top plate 111 of the cabinet air conditioner, an air door 14 is arranged at the first air outlet 12, and an air outlet area 13 is arranged on a wall plate 113; through damper 14, can blow most air current from first air outlet 12 to the top, remaining fractional air current is blown out by the air-out region 13, and the air current velocity of flow that flows out from the air-out region 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, more even, and the wind-borne sensation is softer.

There are various sliding installation manners of the damper 14 on the top plate 111, for example, guide grooves are formed on the left and right inner walls of the first outlet 12, and opposite sides of the damper 14 are inserted into the guide grooves. The user can manually slide the damper 14 back and forth. Of course, a driving device 16 may be provided inside the top plate 111, and the user may drive the damper 14 to slide in the front and rear directions by controlling the driving device 16. In the present embodiment, referring to fig. 4, the damper 14 is slidably mounted to the inner surface of the top plate 111 by a slide assembly 15. The sliding assembly 15 includes a protruding portion disposed on the inner surface of the top plate 111 and corresponding to the protruding portion 15a disposed on two opposite sides of the first air outlet 12, and a protruding portion 15b disposed on two opposite sides of the air door 14, and a sliding slot 151 disposed on the protruding portion 15a and accommodating the protruding portion 15 b. Here, the convex pillar 15b is engaged with the sliding groove 151 to reduce the contact area between the damper 14 and the inner wall of the sliding groove 151, so that the damper 14 slides more smoothly. Further, in order to facilitate the sliding of the damper 14, in another embodiment, the cabinet air conditioner further includes a driving device 16 for driving the damper 14 to slide, the driving device 16 includes a motor 16a, a gear 16b and a rack 16c, the rack 16c is disposed on the damper 14, the motor 16a is mounted on the main body 10, the gear 16b is mounted on the motor 16a, and the rack 16c is engaged with the gear 16 b. By the engagement of the gear 16b with the rack 16c, the sliding of the damper 14 is more stable.

Referring to fig. 5, 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 the plurality of first through holes 13a are provided, the air from the air outlet area 13 can be diffused along the circumferential direction of the cabinet air conditioner. Therefore, the air flow in all directions of the cabinet air conditioner can be convected with the cold air in the air outlet area 13, and further, the heat exchange of the indoor air 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. 6, when the airflow blows to the air door 14, the airflow is blocked by the air door 14, on one hand, the wind power is damaged, and the efficiency of the cabinet air conditioner is reduced; on the other hand, the impact of the airflow against the damper 14 also generates noise. In this embodiment, the damper 14 is provided with a plurality of second through holes 141. In this manner, the effective area of the damper 14 that blocks the airflow is reduced, the wind resistance is greatly reduced, and the noise generated by the airflow impacting the damper 14 is correspondingly reduced.

In addition, when the airflow blows towards the air door 14, condensed water is generated on the back of the air door 14, 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 the disadvantage is caused to users. Due to the existence of the second through hole 141, the air is blocked by the air door 14, a part of the air flow changes direction (for example, forms an angle of 45 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 14 is low, and no condensed water is generated on the back of the air door 14.

Due to the existence of the second through hole 141, after the airflow blown out from the first air outlet 12 passes through the air door 14, 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. 2, 3 and 7, 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, 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 14 is also reduced accordingly.

Referring to fig. 8 and 10 together, in the above embodiment, it is considered that the top cover 111 still obstructs a part of the airflow blown out from the first ventilation hole 211 even though the airflow is blown out from the first ventilation hole 211, thereby reducing the efficiency of the cabinet air conditioner. In this embodiment, the top plate 111 further has a plurality of second ventilation holes 1111 formed 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 reduced after passing through the upper cover plate 21 because the first ventilation holes 211 on the upper cover plate have a noise reduction effect, and after the noise enters the first cavity 1110 between the upper cover plate 21 and the top plate 111, each side wall of the first cavity 1110 absorbs part of the noise again, and when the noise is transmitted to the top plate 111, the noise is partially absorbed again under the action of the second ventilation holes 1111, and finally the noise transmitted from the main body 10 is low.

With continued reference to fig. 8 and 11, considering that the cabinet air conditioner is generally placed against a wall or corner, if the air flowing out of the outlet area 13 blows against the wall, 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, on the basis of the above embodiment, in order to further reduce the noise of the airflow, in this embodiment, an air outlet frame 20 is further disposed in the main body 10, and a plurality of second air outlet holes 221 disposed toward the air outlet region 13 are disposed on the side wall 22 of the air outlet frame. 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.

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 after passing through 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.

In addition, referring to fig. 12, the second air outlet 221 has two ports, one of which is an outer port close to the panel 113a, and the other of which is an inner port opposite to the outer port, in order to make the noise absorption effect of the air outlet frame 20 better, in this embodiment, the inner port of the second air outlet 221 is gradually reduced from the back to the front. Similarly, the first air outlet 131 also has two ports, and in order to make the top plate 111 have better noise absorption effect, the inner port of the first air outlet 131 is gradually reduced from back to front.

Although the noise can enter the air outlet frame 20 and the second cavity 130 in sequence. The noise is reduced through the air outlet frame 20 and the primary noise reductionA part of the noise is filtered, and then a part of the noise is filtered by the second cavity 130. Here, it is considered that the too large aperture of the second air outlet 221 may cause the air molecular vibration effect in the second cavity 130 to be poor, and the noise reduction effect to be also poor. For this purpose, in an embodiment, the aperture a of the second air outlet 221₂Greater than 0 mm and less than or equal to 4 mm. In addition, if the aperture of the second air outlet 221 is too small, the air flow is difficult to pass through, so again, the aperture of the second air outlet 221 is preferably 2mm to 3 mm. Similarly, the aperture a of the first air outlet 131₁Should not be too large, the aperture a of the first air outlet 131₁Greater than 0 mm and less than or equal to 3 mm. Of course a₁Too small, the aperture a of the first outlet 131 is not too small₁In the range of 1mm to 2mm is the preferred embodiment. The aperture a of the second air outlet 221₂Is larger than the aperture a of the first air outlet 131₁. This is because, after being filtered by the air-out frame 20, the remaining noise is relatively small, and the aperture a of the first air-out hole 131₁The size of the second cavity 130 is not necessarily large, but rather the vibration effect of the air in the second cavity is affected, and rather the noise reduction is not good.

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.
