The present invention proposes a kind of cabinet air-conditioner.
Referring to figs. 1 to Fig. 4, cabinet air-conditioner includes main body 10, and main body 10 can be set in cube, or cylindric
Set.The outer surface of main body 10 is general by top board 111, base plate 112, and the wallboard between top board 111 and base plate 112
113 are constituted, wherein, wallboard 113 has panel 113a facing forward, the backboard 113b relative with panel 113a, and connection panel
The side wall of 113a and backboard 113b, here, panel 113a, backboard 113b and side plate can be integrally formed, or divide
What body was set.Heat exchanger 40 and blower fan 30 are provided with main body 10, the air intake entered for extraneous air is provided with wallboard 113
Mouthful, after air is entered by air inlet and exchanged heat with heat exchanger 40 in main body 10, air-flow is blowed into top by blower fan 30, and by air outlet
(the first air outlet 12 and air-out region 13) blows out.
In embodiments of the present invention, cabinet air-conditioner includes that vertically to the main body 10 for extending the main body 10 is interior to be formed with
One air channel inner chamber.The main body 10 includes top board 111 and vertically to the wallboard 113 for extending, one is offered on the top board 111
With the first air outlet 12 of the air channel inner space.The upper end of the wallboard 113 connects the top board 111, the wallboard 113
It is provided with the air-out region 13 for the air-flow outflow in the air channel inner chamber.
Specifically, an outlet frame 20 is typically provided with the inner chamber of air channel, the upper cover plate 21 of outlet frame 20 is provided with opening
210 (reference picture 10 and Figure 13).When blower fan 30 runs, air-flow enters by flowing upwardly toward outlet frame 20 after the heat exchange of heat exchanger 40
On the one hand the air-flow for entering outlet frame 20 is directly over opening and 210 is blown out from the first air outlet 12, on the other hand by air-out region 13
Outflow.To the driving direction of air-flow it is upward due to blower fan 30, thus, after air-flow enters outlet frame 20, by the first air outlet
12 directly blowout can substantially reduce air-flow outflow resistance (prior art be will by outlet frame 20 stop make air-flow blow out angle
Degree changes 90 °, and air-flow that also will be straight up changes over the air-flow that level blows out) so that refrigeration is more preferably.In addition, by
More anxious in the flow velocity of air-flow in the vertical direction, the air pressure of air channel inner chamber is of a relatively high, therefore, a part of air-flow can be from wind outlet area
Slowly flow out in domain 13.
Cabinet air-conditioner is typically put by wall, or is placed in corner.Blown out upwards from the air-flow of the blowout of the first air outlet 12
The air of indoor top half is set to cool down rapidly afterwards, the air flows upwards of indoor the latter half, so that the air of interior is formed
There is heat exchange with the air of the latter half in circulation, the air of indoor top half.In addition, the air-flow flowed out from air-out region 13
Flow velocity is slower, will not blow-through user, but due to the presence in air-out region 13, it is a low-temperature receiver that air-out region 13 nearby becomes,
The air of indoor the latter half also can occur heat exchange with the cold air convection near air-out region 13.Therefore, in the first air-out
Mouthfuls 12 and the collective effect of air-out region 13 under, cabinet air-conditioner not only will not blow-through user, it is indoor and after cabinet air-conditioner operation
Air-flow not only can be in upward and downward convection current, can also be in level to convection current, so that convection effects are preferably, heat exchange is very fast, more
Even, wind sense is softer.
Technical scheme by opening up the first air outlet 12 on the top board 111 of cabinet air-conditioner, in cabinet air-conditioner
Wallboard 113 on air-out region 13 is set, so that most of air-flow can be blowed into top, remaining fraction from the first air outlet 12
Air-flow is blown out by air-out region 13.Air-flow velocity from the outflow of air-out region 13 is slower, will not blow-through user, in addition indoor air flow
Not only can be in upward and downward convection current, can also be in level to convection current, so that convection effects are preferably, heat exchange is very fast, more uniform, wind
Sense is softer.
Reference picture 5 in the lump, in order that the airflow convection in horizontal direction is better, in one embodiment, the air-out
Region 13 include be arranged on the wallboard 113, and the circumferentially-spaced arrangement in the main body 10 multiple first through hole
13a.After setting multiple first through hole 13a, the air from air-out region 13 can spread along the circumference of cabinet air-conditioner, so that,
Positioned at cabinet air-conditioner all directions air-flow all can with the cold air convection current in air-out region 13, and then, room air heat exchange is more equal
It is even.Further, since circumferentially-spaced arrangements of the multiple first through hole 13a along main body 10, therefore, first through hole in a plurality of directions
Under 13a is to the peptizaiton of air pressure in the inner chamber of air channel, the air-flow blown out by the first through hole 13a in all directions is softer.Go out
Wind region 13 can also be other embodiment, such as local open in panel 113a top halfs, to form air-out region 13.
For this kind of situation, a wind-guiding grate 50 (reference picture 3) can be set in the air-out region 13, air-flow is blowed into wider array of angle
Degree.
Reference picture 6, in order that room air can adjust in level to vertical convection current, it is in one embodiment, described
It is provided with to change effective air-out area air door 14 of first air outlet 12 at first air outlet 12.First air outlet 12
When opening completely, the air-flow of the outflow of air-out region 13 is less, and this is unfavorable to the convection current of air-flow to level.By setting up air door 14,
Make the air-out area of the first air outlet 12 adjustable, so user can adjust the throughput that is blown out by the first air outlet 12 with by going out
The ratio of the throughput of the blowout of wind region 13, so that indoor air flow convection effects are more preferably.For example, before air door 14 is set up, by
The throughput of the blowout of the first air outlet 12 accounts for the 85% of total amount, and the throughput blown out by air-out region 13 accounts for the 15% of total amount；It is logical
Air door 14 is overregulated, the effective area for making the first air outlet 12 is the half of original maximum area, its air output is changed into 65%, by
The air-flow total amount of the blowout of air-out region 13 accounts for 35%.Such that it is able to level to airflow convection effect, and upward and downward air-flow pair
Stream effect is adjusted, and can make indoor air flow convection current evenly.
With continued reference to Fig. 6, in above-described embodiment, the mounting means of air door 14 has various, for example, air door 14 is slidably mounted on
Top board 111 or air door 14 are rotated with top board 111 and are connected.In order to avoid air door 14 is adjusting effective outlet air surface of the first air outlet 12
During product, excessive windage is brought to air-flow, in the present embodiment, the air door 14 and the main body 10 rotate be connected and can be in institute
State and overturn at the first air outlet 12.For example, one end of air door 14 rotates with the inwall of air outlet being connected, other end connection motor.
Certainly, the quantity of air door 14 can be for one piece, or two pieces or more.
Reference picture 6 and Fig. 7, when air-flow blows to air door 14, are stopped by air door 14, and wind-force on the one hand can be caused to be damaged,
On the other hand, impact of the air-flow to air door 14 can also produce noise.In the present embodiment, multiple the are offered on the air door 14
Two through holes 141.In this way, stopping that the effective area of air-flow is reduced on air door 14, windage can be substantially reduced, by gas shock air door
14 noises for producing also accordingly are reduced.
Additionally, when air-flow blows to air door 14, the back side of air door 14 can produce condensed water, if do not processed, condensed water can flow
Enter in the inner chamber of air channel, blown out by the first air outlet 12 in turn, unfavorable is caused to user.Due to the presence of the second through hole 141, receive
To the stop of air door 14, a part of airflow direction change (such as with level to angle in 45 °), another part air-flow is logical from second
Passed in hole 141, so that, the air themperature at the back side of air door 14 is relatively low, and the back side of air door 14 will not produce condensed water.
Further, since the presence of the second through hole 141, the air-flow blown out by the first air outlet 12 by after air door 14, one
Point air-flow continues up flowing, a part of air-flow with vertically to blowout in a certain angle so that, the angle that air-flow blows out is wider,
The convection current and heat exchange of indoor air flow are evenly.
In one embodiment, reference picture 9, are provided with outlet frame 20, the upper cover plate 21 of the outlet frame 20 in the inner chamber of air channel
On be provided with one towards the opening 210 of first air outlet 12, be additionally provided with the upper cover plate 21 positioned at it is described opening 210
Multiple first air-vents 211 on periphery.Here, it is larger to the resistance of air-flow in view of the corresponding upper cover plate 21 in the periphery of opening 210,
In this way, when air-flow blows upwards, the noise of generation is larger.After first air-vent 211 is set, resistance reduction of the upper cover plate 21 to air-flow
, the noise produced by gas shock air door 14 also correspondingly reduces.
On the basis of a upper embodiment, reference picture 8 and Figure 10 in the lump, it is contemplated that air-flow blows out from the first air-vent 211
Afterwards, fraction directly can not blow out from the first air outlet 12, therefore, vortex can be formed between upper cover plate 21 and top board 111,
So as on the one hand noise can be produced.To solve this problem, in the present embodiment, it is further opened with being located at institute on the top board 111
State multiple second air-vents 1111 on the periphery of the first opening 210.So, on the one hand, the first air-vent 211 and the second air-vent
1111 setting, can substantially reduce windage loss, improve the efficiency of cabinet air-conditioner.On the other hand, what is produced in main body 10 makes an uproar
Sound, it is finally relatively low from the noise that main body 10 sends by the obstruct of upper cover plate 21 and top board 111.
Reference picture 10, forms one first cavity 1110 between upper cover plate 21 and top board 111, the noise produced in the inner chamber of air channel
By after upper cover plate 21, noise components are absorbed, lower noise, first cavity 1110 is being entered by the first air-vent 211
Afterwards, by first cavity 1110, each side wall is absorbed, and noise reduce further.Therefore it is final by the second air-vent 1111
The noise for spreading out of is relatively small.In order that the noise reduction of the upper cover plate 21 and top board 111 is more preferably, first air-vent
211 with second air-vent 1111 in settings of staggering (in upper cover plate 21 towards being in setting of staggering on the direction of top board 111), with
Noise is avoided directly by outlet frame 20 into directly being spread out of by the second air-vent 1111 after the first cavity 1110, and then so that noise reduction
It is better.
In addition, reference picture 11, above-mentioned first air-vent 211 has two ports, and one of them is be close to top board 111 outer
Port, another port is the inner port relative with external port, in order that upper cover plate 21 to the assimilation effect of noise more preferably, Yu Benshi
Apply in example, the inner port of first air-vent 211 is bottom-up in tapered setting.Equally, above-mentioned second air-vent 1111
With two ports, in order that top board 111 to the assimilation effect of noise more preferably, the inner port of second air-vent 1111 is under
It is in upwards tapered setting.
Although noise can successively enter outlet frame 20 and above-mentioned first cavity 1110.Noise passes through by outlet frame 20
After one-level noise reduction, the noise of a part can be filtered, then another partial noise is filtered by above-mentioned first cavity 1110.Here,
Aperture in view of the first air-vent 211 crosses conference and causes air molecule vibrating effect in the first cavity 1110 not good, noise reduction effect
Fruit is also bad.Therefore, in one embodiment, the aperture d of first air-vent 21113mm is less than or equal to more than 0.In addition, such as
Really the aperture of the first air-vent 211 is too small, air-flow be difficult to through, so, the aperture of the first air-vent 211 is in 1.5mm to 2.5mm
It is better embodiment.Equally, the aperture d of the second air-vent 11112Unsuitable excessive, the aperture d of the second air-vent 11112More than 0
Less than or equal to 2mm；Certain d2It is not easy to too small, the aperture d of the second air-vent 1111 herein2It is preferably implementation in 1mm to 1.5mm
Mode.It should be noted that the aperture d of first air-vent 2111It is greater than the aperture d of second air-vent 11112.This
Because, after the upper cover plate 21 of outlet frame 20 is filtered, remaining noise is relatively small, the aperture d of the second air-vent 11112
There is no need to be made larger, be made the larger vibrating effect that can influence air in the first cavity 1110 on the contrary.
Reference picture 4, Figure 13 and Figure 14, it is contemplated that cabinet air-conditioner is typically seated in by wall displacement or corner, if by going out
The air of the outflow of wind region 13 is to blowing by force, it will reduce the efficiency of cabinet air-conditioner.In one embodiment, in order that air-out region 13
The air of blowout is main from panel 113a outflows, so that wind sense in front of panel 113a is nice and cool, soft, the air-out region 13
Including multiple first exhaust vents 131 being arranged on the panel 113a.Because air-flow blows out from panel 113a in the inner chamber of air channel
Amount it is smaller, and multiple first exhaust vents 131 are offered on panel 113a, therefore, air-flow blows out more from the first exhaust vent 131
It is soft.Furthermore, the panel 113a for offering the first exhaust vent 131 there is absorption to make the noise that air-flow in the inner chamber of air channel is produced
With such that it is able to reach the purpose of noise reduction.
Equally, it is in the present embodiment, described in order to further reduce the noise of air-flow on the basis of a upper embodiment
An outlet frame 20 is additionally provided with main body 10, is offered on the side wall 22 of the outlet frame and is provided with towards the air-out region 13
Multiple second exhaust vents 221.In this way, the noise produced in main body 10, by the obstruct of outlet frame 20 and front panel 113a, finally
The noise sent from front panel 113a is relatively low.
The second cavity 130 is formed between outlet frame 20 and front panel 113a, the noise produced in the inner chamber of air channel is by air-out
After frame 20, noise components are absorbed, lower noise.Then after the first exhaust vent 131 enters second cavity 130, it is subject to
The absorption of second cavity 130 each side wall, noise reduce further.Therefore it is final by making an uproar that the first exhaust vent 131 spreads out of
Sound is relatively small.In order that the noise reduction of the outlet frame 20 and front panel 113a is more preferably, first exhaust vent 131 and institute
The second exhaust vent 221 is stated in settings of staggering (front and rear to staggering), to avoid noise directly by the second cavity of entrance of outlet frame 20
Directly spread out of by the first exhaust vent 131 after 130, and then cause noise reduction more preferably.
In addition, the second exhaust vent 221 has two ports, one of them is the external port for being close to panel 113a, the other end
Mouthful be the inner port relative with external port, in order that outlet frame 20 to the assimilation effect of noise more preferably, it is described in the present embodiment
The inner port of the second exhaust vent 221 is in from back to front tapered setting.Equally, above-mentioned first exhaust vent 131 also has two ports,
In order that top board 111 to the assimilation effect of noise more preferably, the inner port of first exhaust vent 131 sets in tapered from back to front
Put.
Although noise can successively enter outlet frame 20 and above-mentioned second cavity 130.Noise passes through by outlet frame 20
After one-level noise reduction, the noise of a part can be filtered, then another partial noise is filtered by above-mentioned second cavity 130.Here, examining
The aperture for considering the second exhaust vent 221 crosses conference and causes air molecule vibrating effect in the second cavity 130 not good, noise reduction
It is bad.Therefore, in one embodiment, the aperture a of second exhaust vent 22124mm is less than or equal to more than 0.In addition, if the
The aperture of two exhaust vents 221 is too small, air-flow be difficult to through, so, again, the aperture of the second exhaust vent 221 is in 2mm to 3mm
Better embodiment.Equally, the aperture a of the first exhaust vent 1311Unsuitable excessive, the aperture a of the first exhaust vent 1311It is less than more than 0
