Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes a double air outlet structure of a cabinet air conditioner and the cabinet air conditioner according to the present invention with reference to fig. 1 to 9.
Fig. 1 is a schematic cross-sectional view of a prior art cabinet air conditioner along the horizontal direction.
As shown in fig. 1, the conventional cabinet air conditioner has a cabinet 1; the shell 1 is provided with a front panel, the wall surface of the shell 1 facing the front panel is provided with an air inlet, and the front panel is provided with two air outlets; a double-through-flow air duct 4 is arranged in the shell 1, an evaporator 2 is arranged between an air inlet end and an air inlet of the double-through-flow air duct 4, the evaporator 2 is in a U-shaped structure, so that the middle of the evaporator 2 is opposite to the two air inlet ends of the double-through-flow air duct 4, and the two ends of the evaporator 2 are located on the opposite sides of the two air inlet ends.
Meanwhile, the cross-flow fans 3 are arranged at the air inlet ends of the double cross-flow air ducts 4 in a one-to-one correspondence manner; two air outlet ends of the double cross-flow air duct 4 are respectively arranged opposite to the two air outlets one by one; the double-through-flow air duct 4 comprises two air ducts which are symmetrically arranged, and the air outlet ends of the two air ducts extend along mutually divergent directions; two air-out ends in two through-flow wind channel 4 all are equipped with pendulum leaf subassembly 5, and pendulum leaf subassembly 5 includes a plurality of pendulum leaves, and the air-out end is rotationally located to the pendulum leaf.
Based on the design form of the cabinet air conditioner, although based on the guiding effect of the swing blade assembly 5 on the air supply flow in the air duct, when the cabinet air conditioner is exhausted through the two air outlets, the air outlet inclined to the left side and the air outlet inclined to the right side can be respectively controlled relative to the position of the cabinet air conditioner, and the air is exhausted to the front side and the air is simultaneously exhausted to the left side and the right side, the air outlet parameters of the cabinet air conditioner are limited by the inherent design form of the double-through-flow air duct 4, and the realization of large air volume, wide angle and remote air outlet based on the existing air outlet structure is difficult to further improve.
As shown in fig. 2 to 7, based on the problems existing in the prior art, the present embodiment provides a dual air outlet structure of a cabinet air conditioner, and the dual air outlet structure further optimally designs a wind shielding assembly 6 on the basis of the dual through-flow duct 4 and the swing blade assembly 5 shown in the above embodiments; the wind shielding assemblies 6 shown in the embodiment are provided with two sets and correspond to the two air outlet ends of the double through-flow air duct 4 one by one; the wind shielding assembly 6 comprises a first driving mechanism and a wind shielding plate 61, wherein the first driving mechanism is connected with the wind shielding plate 61 so as to drive the wind shielding plate 61 to switch between a first position for shielding the wind outlet end and a second position for opening the wind outlet end; under the condition that the wind deflector 61 is in the second position, part of the structure of the wind deflector 61 is connected with the wind outlet end along the extending direction of the wind outlet end corresponding to the wind deflector, so as to guide the wind flow passing through the swing blade assembly 5.
Specifically, in the embodiment, the double through-flow air duct 4, the swing blade assembly 5 and the wind shielding assembly 6 are arranged; when the air outlet direction of the two air outlet ends of the double through-flow air duct 4 is regulated and controlled by the swing blade assembly 5, the air baffle 61 of the wind shielding assembly 6 can also be used for extending the double through-flow air duct 4 when being positioned at the second position, so that the cabinet air conditioner can realize large air quantity, wide angle and long-distance air outlet, and the user experience is improved.
As shown in fig. 3, when the cabinet air conditioner is in a shutdown state, that is, when the cabinet air conditioner does not output air into the operating space of the cabinet air conditioner, each of the swing vanes corresponding to the swing vane assembly 5 shown in this embodiment is perpendicular to the axisymmetric plane of the double through-flow air duct 4, so that the opposite end portions of two adjacent swing vanes are connected, and thus two air output ends of the double through-flow air duct 4 are closed; meanwhile, the wind shield 61 of the wind shield assembly 6 shown in this embodiment is in the first position to close the outlet of the cabinet air conditioner.
As shown in fig. 4, when the cabinet air conditioner is inclined to the left side to discharge air, each of the swing blades corresponding to the swing blade assembly 5 shown in this embodiment is inclined to the left side, so that a plurality of air discharge gaps inclined to the left side are formed between two adjacent swing blades, and the air blocking plate 61 of the air blocking assembly 6 is in the second position to open the air discharge end of the double cross flow duct 4. Therefore, when the cross flow fans 3 at the two air inlet ends corresponding to the double cross flow air ducts 4 are started, the two air outlet ends corresponding to the double cross flow air ducts 4 can simultaneously tilt to exhaust air to the left side. Because when deep bead 61 is in the second position, partial structure on deep bead 61 has still prolonged two through-flow wind channel 4's length along the extending direction of two through-flow wind channel 4's air-out end, thereby when making two air outlets of cabinet air conditioner air-out simultaneously, the wind air supply stream can incline towards the left the place ahead of cabinet air conditioner more, and then increased the angular range to the left side slope air-out, and simultaneously, the wind speed of cabinet air conditioner air-out is bigger and more concentrated, air loss among the air supply process has been reduced, the wind distance of the left side slope air-out has been promoted.
As shown in fig. 5, when the cabinet air conditioner is inclined to the right side to discharge air, each of the swing blades corresponding to the swing blade assembly 5 shown in this embodiment is inclined to the right side, so that a plurality of air discharge gaps inclined to the right side are formed between two adjacent swing blades, and the air blocking plate 61 of the air blocking assembly 6 is in the second position to open the air discharge end of the double cross flow duct 4. Therefore, when the cross flow fans 3 at the two air inlet ends corresponding to the double cross flow air ducts 4 are started, the two air outlet ends corresponding to the double cross flow air ducts 4 can simultaneously tilt to the right side for air outlet. Because when the deep bead 61 is in the second position, partial structure on the deep bead 61 has still prolonged the length in two through-flow wind channel 4 along the extending direction of the air-out end in two through-flow wind channel 4, thereby when making two air outlets of cabinet air conditioner air-out simultaneously, the wind air supply current can incline towards the right front of cabinet air conditioner more, and then increased the angular range of the air-out of slope to the right side, and simultaneously, the wind speed of cabinet air conditioner air-out is bigger and more concentrated, the air loss of the air supply in-process has been reduced, the wind supply distance of the air-out of slope on the right side has been promoted.
As shown in fig. 6, when the cabinet air conditioner is ventilated to the front of the cabinet air conditioner, each of the swing blades corresponding to the swing blade assembly 5 shown in this embodiment is parallel to the axisymmetric plane of the dual through-flow duct 4, so that a plurality of air outlet gaps extending to the front of the cabinet air conditioner are formed between two adjacent swing blades, and the wind shield 61 of the wind shield assembly 6 is located at the second position to open the air outlet end of the dual through-flow duct 4. Therefore, when the cross flow fans 3 at the two air inlet ends corresponding to the double cross flow air ducts 4 are started, the two air outlet ends corresponding to the double cross flow air ducts 4 both can discharge air to the air conditioner cabinet in the front direction. Because the wind shield 61 is in the second position, the arrangement of the wind shield 61 does not affect the air outlet flow of the cabinet air conditioner to the right front.
As shown in fig. 7, when the cabinet air conditioner is tilted to the left and right sides of the cabinet air conditioner to discharge air, the swing blades at the air discharge end on the left side of the dual through-flow duct 4 are tilted to the left side, the swing blades at the air discharge end on the right side of the dual through-flow duct 4 are tilted to the right side, and the wind shield 61 of the wind shield assembly 6 is in the second position to open the air discharge end of the dual through-flow duct 4. Based on the air outlet principle, obviously, when the cabinet air conditioner is used for simultaneously discharging air from the left and the right, the cabinet air conditioner has a wide-angle air outlet range and can realize remote air outlet.
It should be noted that in fig. 4 to 7, the dashed lines with arrows indicate the flow direction of the airflow during the air supply of the cabinet air conditioner.
Based on the solution shown in the above embodiment, in order to further ensure the wide-angle air outlet range of the cabinet air conditioner, both air ducts corresponding to the dual through-flow air duct 4 shown in this embodiment include a through-flow volute 41 and a through-flow volute tongue 42; the through-flow volutes 41 and the through-flow volute tongues 42 of the two air ducts are symmetrically arranged relative to the axial symmetry plane of the double through-flow air duct 4, and the through-flow volutes 41 of the two air ducts are arranged in a back direction and are close to or connected with each other; the second position shown in this embodiment is located on a side of the crossflow volute tongue 42 facing away from the crossflow volute 41, and when the wind deflector 61 is located at the second position, part of the structure of the wind deflector 61 is connected to an end of the crossflow volute tongue 42 along an extending direction of the wind outlet end corresponding to the wind deflector. The two air outlet ends of the double cross-flow duct 4 shown in this embodiment are spaced, and the included angle formed by the extending directions of the two air outlet ends is a right angle or an obtuse angle.
Specifically, the air duct is designed to be a combined structure composed of the through-flow volute 41 and the through-flow volute tongue 42, so that the air duct on the left side of the double-through-flow air duct 4 extends along a first circular arc track, and the air duct on the right side of the double-through-flow air duct 4 extends along a second circular arc track. The starting point of the first arc track is positioned at the air inlet end of the air duct on the left side of the double through-flow air duct 4, and the ending point of the first arc track is positioned at the air outlet end of the air duct on the left side of the double through-flow air duct 4; correspondingly, the starting point of the second circular arc track is located at the air inlet end of the air duct on the right side of the double through-flow air duct 4, and the ending point of the second circular arc track is located at the air outlet end of the air duct on the right side of the double through-flow air duct 4. Obviously, because the through-flow volutes 41 of the two air ducts are arranged in a back-to-back manner, the two air outlet ends of the double-through-flow air duct 4 extend in mutually divergent directions, which enables the cabinet air conditioner to have a wide air outlet range.
Here, when the air outlet is regulated, in this embodiment, the end of the cross flow volute tongue 42 is extended along the extending direction of the air outlet end corresponding to the partial structure on the wind shield 61, which correspondingly increases the air outlet area and the air supply angle of the two air outlet ends of the dual cross flow duct 4.
Further, the wind deflector 61 shown in the present embodiment has a first surface, a second surface, and a third surface; the first surface is opposite to the third surface, and the second surface is formed at the first end of the wind deflector 61. Under the condition that the wind shield 61 is at the first position, the first surface is parallel to the end surface of the front panel of the cabinet air conditioner, the third surface faces the air outlet end, and the end surface of the front panel is perpendicular to the axial symmetry plane of the double through-flow air duct 4. In order to ensure the smoothness of the air outlet, in the present embodiment, when the air baffle 61 is in the second position, the first end of the air baffle 61 is connected to the end of the through-flow volute tongue 42, and the second surface is flush with one side of the through-flow volute tongue 42 facing the through-flow volute 41.
It should be noted that, when the wind deflector 61 is in the second position, in order to ensure that the second surface of the wind deflector 61 can better cooperate with one side surface of the cross flow volute tongue 42 facing the cross flow volute 41 so as to guide the wind outlet direction of the wind outlet end, the first surface and the second surface of the wind deflector 61 are arranged at an acute angle, for example, the included angle between the first surface and the second surface may be specifically 10 °, 15 °, 20 °, 30 °, and the like, and is not specifically limited herein. Obviously, the angle between the first and second surfaces is determined by the angle of inclination of the end of the volute tongue 42 facing the air outlet side relative to the horizontal.
As shown in fig. 3 to 7, the first driving mechanism of the present embodiment includes a driving member and a guiding rail assembly 62; the guide rail assembly 62 comprises a linear guide rail 621 and an arc guide rail 622, the extending direction of the linear guide rail 621 is parallel to the axial symmetry plane of the double-through-flow air duct 4, the projection of the first end of the arc guide rail 622 on the horizontal plane is positioned in the projection area formed by the air duct on the horizontal plane, and the projection of the second end of the arc guide rail 622 on the horizontal plane is positioned outside the projection area; the wind shield 61 is provided with a first movable contact 611 and a second movable contact 612; the first moving contact 611 is movably provided to the linear guide 621; the second movable contact 612 is movably arranged on the arc guide 622; the driving member is connected to the first moving contact 611 to drive the first moving contact 611 to reciprocate along the linear guide 621.
Specifically, the double cross-flow air duct 4 and the wind shield 61 both extend along the height direction of the cabinet air conditioner; in order to facilitate the arrangement of the guide rail assembly 62 by making full use of the limited inner space of the cabinet air conditioner to guide the movement of the wind deflector 61 based on the guide rail assembly 62, the guide rail assembly 62 is provided on the upper side and/or the lower side of the wind deflector 61. That is, the present embodiment may provide a set of rail assemblies 62, and locate the rail assemblies 62 on the upper or lower side of the wind deflector 61; alternatively, in this embodiment, two sets of guide rail assemblies 62 may be provided, and the guide rail assemblies 62 are provided on the upper and lower sides of the wind deflector 61, so that the two sets of guide rail assemblies 62 simultaneously guide the moving process of the wind deflector 61.
Meanwhile, in order to adapt to the arrangement of the rail assembly 62, the first moving contact 611 and the second moving contact 612 shown in the present embodiment are provided at the upper end or the lower end of the wind deflector 61 at the same time.
In order to facilitate the control of the movement of the wind deflector 61 between the first position and the second position, the present embodiment provides the first moving contact 611 near the second end of the wind deflector 61, and the second moving contact 612 near the first end of the wind deflector 61, the first end and the second end of the wind deflector 61 being opposite to each other. The distance between the first moving contact 611 and the second moving contact 612 is determined according to the trajectory of the linear guide 621 and the arc guide 622 for guiding the wind deflector 61 and the size parameter of the flow-through volute tongue 42.
Obviously, the present embodiment is based on the optimized setting of the rail assembly 62 and the distance between the first moving contact 611 and the second moving contact 612, when the driver drives the first moving contact 611 to move along the linear rail 621 toward the rear side of the cabinet air conditioner, the wind deflector 61 can be enabled to gradually bypass the end of the cross flow volute tongue 42 from the first position to the second position; accordingly, as the driver drives the first moving contact 611 to move along the linear guide 621 toward the front side of the cabinet air conditioner, the wind guard 61 may be caused to gradually bypass the end of the crossflow volute tongue 42 from the second position to the first position.
It should be noted here that in one embodiment, the first moving contact 611 may be a driving wheel and the second moving contact 612 may be a driven wheel; the driving member shown in this embodiment is a rotation driving mechanism, and an output end of the rotation driving mechanism is connected to the driving wheel to drive the driving wheel to roll along the linear guide 621.

As shown in fig. 4, in this embodiment, based on the structural design of the air guide head 7, when each of the swing blades of the swing blade assembly 5 inclines to the left side, both air outlet ends corresponding to the double through-flow air ducts 4 all output air to the left side, at this time, according to the adsorption characteristics of the air flow on the solid surface, the right side surface of the air guide head 7 can generate an adsorption effect on the air outlet of the right side air duct of the double through-flow air duct 4, so that the air flow output from the air outlet end on the right side of the through-flow air duct actively converges toward the air outlet end on the left side of the through-flow air duct, which not only can prevent air volume loss, but also increases the air speed and the air delivery distance of the cabinet air conditioner towards the left air outlet.
As shown in fig. 5, in this embodiment, based on the structural design of the air guiding head 7, when each of the swing blades of the swing blade assembly 5 inclines to the right side, the two air outlet ends corresponding to the two through-flow air ducts 4 all output air to the right side, at this time, according to the adsorption characteristic of the air flow on the solid surface, the left side of the air guiding head 7 can generate an adsorption effect on the air outlet of the left air duct of the two through-flow air ducts 4, so that the air flow output from the air outlet end on the left side of the through-flow air duct actively converges toward the air outlet end on the right side of the through-flow air duct, which not only can prevent air loss, but also increases the air speed and the air delivery distance of the cabinet air conditioner towards the air outlet on the right side.
Furthermore, in order to adapt to the structural design of the air guide head 7 and ensure the structural aesthetic property of the cabinet air conditioner, the embodiment is also provided with a sealing component 8; when the wind shields 61 corresponding to the two air outlet ends are in the first positions, a gap is formed between the opposite end parts of the wind shields 61 corresponding to the two air outlet ends; the closing assembly 8 comprises a second driving mechanism and a closing plate; the second driving mechanism is connected with the closing plate; the closing plate extends along the height direction of the cabinet air conditioner; with the wind deflector 61 in the first position, the second drive mechanism is used to drive the closure panel to close the gap.
It should be noted that the second driving mechanism shown in this embodiment may be a linear driving mechanism, and the closing plate may be controlled to close the gap or open the gap by driving the closing plate to move up and down. Of course, the second driving mechanism shown in this embodiment may also be a rotary driving mechanism, and the closing plate may also be controlled to close or open the gap by driving the closing plate to turn over along the axis where the height direction of the cabinet air conditioner is located.
Further, the sealing assembly 8 shown in this embodiment includes two sealing plates, one side of each of the two sealing plates is rotatably connected to an edge of the wind guide head 7, and the edge is opposite to the bottom surface of the wind guide head 7; the second driving mechanism is in power coupling connection with the two closing plates so as to drive the two closing plates to be switched between a first state and a second state; in the first state, the two closing plates are respectively vertical to the axial symmetry plane of the double through-flow air duct 4 to close the gap; in the second state, the two sealing plates are attached to two side surfaces of the wind guide head 7 in a one-to-one correspondence manner.

Because servo motor can drive second gear and third gear and rotate along opposite direction of rotation when driving first gear and rotate based on the transmission effect of first gear to this embodiment accessible control servo motor turns to, controls two closing plates and switches between first state and second state.
Based on the solutions shown in the above embodiments, in order to more vividly describe the guiding effect of the dual air-out structure shown in this embodiment on the wind direction, the present embodiment respectively performs simulation research on the existing air-out structure and the dual air-out structure shown in this embodiment, and obtains the simulation line diagrams shown in fig. 8 and 9. Fig. 8 and 9 are simulated flow charts of air outlet from the left direction for the air conditioner.
Based on the simulation flow chart shown in fig. 8, it can be known that, because the length of the air duct of the existing air outlet structure is fixed, the air outlet angle and the air outlet intensity of the air outlet end located on the left side of the double through-flow air duct 4 are obviously limited when air is discharged from the left side. Although the two air outlet ends of the double through-flow air duct 4 both face the left side to exhaust air under the guidance of the swing blades of the swing blade assembly 5, because the air guide head 7 shown in this embodiment is not arranged between the two air outlet ends of the double through-flow air duct 4, the air outlet at the air outlet end on the right side of the double through-flow air duct 4 is conveyed forward for a distance and then converged with the air flow on the left side, which generates a large air volume loss on one hand and also affects the air outlet angle of the air conditioner cabinet facing the left side as a whole on the other hand. The angle of the outlet direction of the outlet airflow toward the left side shown in fig. 8 with respect to the axisymmetrical plane of the double cross-flow duct 4 is approximately 35 °.
On the contrary, as can be seen from the simulated flow chart shown in fig. 9, since the end of the cross flow volute tongue 42 is extended by the second surface of the wind deflector 61 in the present embodiment, when the left wind is blown out, the wind outlet end located on the left side of the dual cross flow duct 4 can obtain a larger wind outlet angle and wind outlet strength. Meanwhile, based on the adsorption and guide effects of the right side face of the air guide head 7 on the right side air outlet of the double through-flow air duct 4, the air flow output from the air outlet end on the right side of the through-flow air duct can be ensured to be actively converged towards the air outlet end on the left side of the through-flow air duct, so that air quantity loss can be prevented, and the air speed and the air delivery distance of the cabinet air conditioner towards the right side air outlet are increased. The outlet direction of the outlet airflow to the left shown in fig. 9 is approximately 60 ° with respect to the axial symmetry plane of the double through-flow duct 4.
Obviously, the present embodiment can ensure that the cabinet air conditioner can supply air in a large-angle, long-distance and large-air-volume air supply mode based on the improvement of the above embodiments.
As shown in fig. 1 and fig. 2, the present embodiment further provides a cabinet air conditioner, including: a housing 1; the casing 1 is provided with a front panel, the wall surface of the casing 1 facing the front panel is provided with an air inlet, and the front panel is provided with two air outlets; further comprising: the double air outlet structure of the cabinet air conditioner is arranged in the machine shell 1 and is used for exhausting air to the outside; cross flow fans 3 are arranged at the air inlet ends of the double cross flow air ducts 4 in a one-to-one correspondence manner; two air outlet ends of the double-through-flow air duct 4 are respectively arranged opposite to the two air outlets one by one.
Specifically, since the cabinet air conditioner shown in this embodiment includes the dual air outlet structure of the cabinet air conditioner, and the specific structure of the dual air outlet structure of the cabinet air conditioner refers to the above embodiments, since the cabinet air conditioner employs all technical solutions of all the above embodiments, at least all beneficial effects brought by the technical solutions of the above embodiments are achieved, and are not repeated here.
Furthermore, in order to ensure the overall aesthetic property of the cabinet air conditioner, when the wind shield 61 is in the second position, the wind shield 61 is stored in the casing 1 of the cabinet air conditioner, and a storage space 9 is arranged between the casing 1 and the opposite wall surfaces of the double-through-flow air duct 4 in the embodiment; when the wind deflector 61 is in the second position, the wind deflector 61 is located in the housing space 9; an avoiding channel is arranged between the casing 1 and the air outlet end of the double cross-flow air duct 4 and is used for the wind shield 61 to pass through, so that the wind shield 61 can be switched between the first position and the second position.
