The invention provides a wall-mounted indoor unit and an air conditioner comprising the same, wherein the wall-mounted indoor unit can realize air outlet without wind sense so as to improve the comfort level of a user using the wall-mounted indoor unit.
Referring to fig. 1 to 3, the wall-mounted indoor unit of the present invention includes a housing 100 having an air outlet, a first wind deflector 10 and a second wind deflector 20; the first wind deflector 10 is movably arranged at the air outlet and is positioned at the upper end of the air outlet; the second wind guard 20 is movably installed at the lower end of the air outlet, and the second wind guard 20 and the first wind guard 10 at the lower end of the air outlet are both provided with wind-dispersing holes. The wall-mounted indoor unit further comprises a first driving device (not shown) and a second driving device (not shown) which are installed in the casing 100, wherein the first driving device is connected with the first wind deflector 10 and is used for driving the first wind deflector 10 to move up and down to be close to or far from the air outlet; the second driving device is connected to the second wind deflector 20, and is used for driving the second wind deflector 20 to move up and down to get close to or far away from the air outlet. When both the first wind deflector 10 and the second wind deflector 20 are rotated to the air outlet, one of the first wind deflector 10 and the second wind deflector 20 is covered on the other.
Specifically, the top of the housing 100 has an air inlet 111, and the heat exchanger 200 and the wind wheel 300 are sequentially disposed inside the housing 100 below the air inlet 111; the casing 100 includes a panel 110, and the air outlet is disposed at a lower end of the panel 110. When the indoor unit of the air conditioner works, indoor air flow enters from the air inlet 111, exchanges heat through the heat exchanger 200, and flows to the air outlet to be sent out by being driven by the wind wheel 300.
When the first wind deflector 10 and the second wind deflector 20 rotate to the air outlet, the first wind deflector 10 covers the air outlet, and the second wind deflector 20 covers the first wind deflector 10; or the second wind deflector 20 covers the air outlet, and the first wind deflector 10 covers the second wind deflector 20. In the following embodiments, the foregoing previous coverage is explained as an example.
Because the first wind shield 10 and the second wind shield 20 are provided with the air-dispersing holes in a penetrating manner, when the air-out airflow passes through the air-dispersing holes in the first wind shield 10 and/or the second wind shield 20, the wind speed of the air-out airflow is reduced, and the air-out airflow is dispersed and softened, so that the wind speed of the air-out airflow blown into a room is smaller and softer, and the user cannot feel the flow of the air-out airflow, thereby achieving the effect of air-out without wind sensation.
The wall-mounted indoor unit comprises a controller (not shown), wherein the controller can control the first driving device and the second driving device to synchronously drive the first wind deflector 10 and the second wind deflector 20 to move; the controller may also control the first and second drive means to independently drive the movement of the first and second wind deflectors 10, 20, respectively.
According to the technical scheme of the invention, the first wind deflector 10 and the second wind deflector 20 are arranged at the air outlet of the shell 100, the second wind deflector 20 and the first wind deflector 10 are respectively provided with a wind dispersing hole in a penetrating way, the first wind deflector 10 is movably arranged at the air outlet and is positioned at the upper end of the air outlet, and the second wind deflector 20 is movably arranged at the air outlet and is positioned at the lower end of the air outlet; the first wind deflector 10 and the second wind deflector 20 are driven to move by the first driving device and the second driving device respectively, so that the first wind deflector 10 and the second wind deflector 20 are gradually laminated in the moving process of the first wind deflector 10 and/or the second wind deflector 20, wherein the part of the first wind deflector 10 and the second wind deflector 20 which are not laminated only forms a layer of wind shielding structure, and the scattering of the air flow of the air outlet is weak, so that no wind sensation is weak; the two overlapped parts form a double-layer wind shielding structure, have strong stopping effect on the air flow of the air outlet, and can strengthen the air outlet without wind sensation or completely stop the air outlet. Therefore, the wall-mounted indoor unit can realize no-wind-sense air outlet so as to prevent air outlet airflow from being directly blown to a user, improve the comfort level of the wall-mounted indoor unit, and adjust the size of the air outlet so as to change the air outlet area.
The wall-mounted indoor unit controls the first wind deflector 10 and the second wind deflector 20 to move to different positions through the controller, so that various air outlet modes of the wall-mounted indoor unit can be realized.
Referring to fig. 3, in this mode, the first wind deflector 10 moves above the air outlet, and the second wind deflector 20 moves below the air outlet. The mode is a conventional air outlet mode, and the air outlet air flow can be directly blown out from the air outlet, so that the mode is suitable for the initial stage of cooling/heating and is used for realizing rapid cooling/heating.
Referring to fig. 4, in this mode, the first wind deflector 10 and the second wind deflector 20 are both moved to the air outlet, and the second wind deflector 20 is partially laminated with the first wind deflector 10. The mode is a layering wind-sensing-free wind outlet mode, at the moment, the upper end of the wind outlet is deviated to the upper wind-sensing-free wind outlet, the lower end of the wind outlet is deviated to the lower wind-sensing-free wind outlet, and the wind outlet direction is not blown to a user; the lamination part of the second wind deflector 20 and the first wind deflector 10 is located in the middle of the air outlet, so that the stopping effect of the middle of the air outlet is stronger, and the air outlet without wind sensation can be enhanced or the air outlet can be completely stopped.
As can be seen from the above-mentioned no-wind-sensation air-out mode, when the wall-mounted indoor unit controls the first wind deflector 10 and the second wind deflector 20 to move independently through the controller, by controlling the first wind deflector 10 and the second wind deflector 20 to be stacked at different positions, another no-wind-sensation air-out mode of the air outlet can be realized:
referring to fig. 5, in this mode, the first wind deflector 10 covers the air outlet, and the controller controls the second wind deflector 20 to move upwards until a part of the second wind deflector is overlapped with the first wind deflector 10, and the overlapped part of the second wind deflector and the first wind deflector gradually increases upwards from the lower end of the air outlet. Therefore, in the wind-sensing-free wind outlet mode, the wind outlet face of the wind outlet is gradually reduced and increased, and the wind outlet airflow is deflected upwards to wind, and is softer.
Referring to fig. 2 and 3, in the present embodiment, the first wind deflector 10 and the second wind deflector 20 can rotate, slide or swing. Taking the first wind deflector 10 as an example for explanation, the mounting manner of the second wind deflector 20 may be set with reference to the moving manner of the first wind deflector 10:
the first wind deflector 10 is slidably mounted at the upper end of the air outlet, and accordingly, the panel 110 is provided with two sliding rails extending up and down and arranged at intervals along the length direction of the air outlet, and a windward side of the first wind deflector 10 is provided with sliding bars correspondingly mounted with the sliding rails. The first driving device comprises a first motor and a gear connected with the first motor, a rack extending along the length direction of the first motor is arranged on a sliding rod of the first wind deflector 10, and the rack is meshed with the gear so as to drive the first wind deflector 10 to slide through the driving of the first motor.
Or, the first wind deflector 10 is installed at the upper end of the air outlet in a swinging manner, and accordingly, the first driving device comprises a first motor and a swing arm support connected with the first motor, the swing arm support is provided with two swing arms connected with the first wind deflector 10, and the first motor drives the swing arm support to swing so as to drive the first wind deflector 10 to swing up and down. In order to avoid mutual interference between the cranks of the first wind deflector 10 and the second wind deflector 20, the first wind deflector 10 and the second wind deflector 20 are provided with avoiding grooves for giving way to the swing arms, or the length of the first wind deflector 10 is smaller than that of the second wind deflector 20, two cranks of the first wind deflector 10 are respectively arranged at two ends of the first wind deflector 10, and two swing arms of the second wind deflector 20 are respectively arranged at two ends of the second wind deflector 20.
Referring to fig. 2 and 3, in the present embodiment, the outer contour of the casing 100 is generally arc-shaped, so that the wall-mounted indoor unit has a better overall appearance. Therefore, in order to facilitate the first wind deflector 10 and the second wind deflector 20 to move up and down along the outer side of the housing 100, preferably, the plate surfaces of the first wind deflector 10 and the second wind deflector 20 are all arranged in an arc shape with concave outer sides from top to bottom, so that the first wind deflector 10 and the second wind deflector 20 can move up and down along the outer side of the housing 100, and the first wind deflector 10 and the second wind deflector 20 can be better matched in a lamination manner no matter in the moving process.
In the present embodiment, based on the above embodiment, in order to enable the first wind deflector 10 and the second wind deflector 20 to have a large lamination surface, the magnitudes of the radians corresponding to the first wind deflector 10 and the second wind deflector 20 are equivalent. By this arrangement, the arcuate surfaces of the first and second wind deflectors 10, 20 are made to be equal in size, and when the two are laminated, a large laminated surface is obtained.
Referring to fig. 2 and 3, in the present embodiment, in order to completely close the air outlet when the wall-mounted indoor unit is not in operation, the first wind deflector 10 and the second wind deflector 20 can prevent foreign matters such as dust from entering the housing 100, so that when one of the first wind deflector 10 and the second wind deflector 20 completely covers the other, the air holes on the first wind deflector 10 and the air holes on the second wind deflector 20 are staggered.
Specifically, when the first wind deflector 10 and the second wind deflector 20 both rotate to the air outlet, the first wind deflector 10 covers the air outlet, the second wind deflector 20 covers the first wind deflector 10, and the air dispersing holes on the first wind deflector 10 and the air dispersing holes on the second wind deflector 20 are staggered mutually, so that the first wind deflector 10 and the second wind deflector 20 are matched to completely seal the air outlet.
It should be noted that the air holes on the first air deflector 10 and the air holes on the second air deflector 20 are staggered, which means that the projections of the air holes on the first air deflector 10 and the air holes on the second air deflector 20 in the air outlet direction are completely staggered, so as to ensure that the foreign matters such as dust in the external environment are difficult to enter into the housing 100 through the air holes on the first air deflector 10 and the second air deflector 10.
Referring to fig. 4, in another embodiment, in order to enhance the windless air outlet effect of the wall-mounted indoor unit, the air outlet holes on the first air deflector 10 and the second air deflector 20 are both arranged in a long strip shape; and in the first wind deflector 10 and the second wind deflector 20, the extending direction of the air dispersing holes on one wind deflector and the extending direction of the air dispersing holes on the other wind deflector are arranged in a cross mode.
The cross-shaped arrangement mode is not particularly limited, and various modes are available. For example, mode one: as shown in fig. 6, the plurality of air-dispersing holes on the first wind deflector 10 extend along the length direction of the air outlet and are uniformly distributed at intervals along the width direction of the air outlet; the plurality of air dispersing holes on the second wind guard 20 extend along the width direction of the air outlet and are uniformly distributed at intervals along the length direction of the air outlet.
For another example, mode two: as shown in fig. 7, the plurality of air dispersing holes on the first wind deflector 10 extend toward the same side obliquely, and are uniformly distributed at intervals along the length direction of the air outlet; the inclined extending direction of the plurality of air-diffusing holes on the second air-blocking plate 20 is arranged to intersect with the extending direction of the air-diffusing holes on the first air-blocking plate 10.
The above-mentioned two kinds of cross form setting methods, when all can be in first deep bead 10 and second deep bead 20 range upon range of, the wind hole on the first deep bead 10 and the wind hole on the second deep bead 20 intercrossing, so can make the range upon range of position of first deep bead 10 and second deep bead 20 break up the effect stronger to the wind-out air current to reinforcing first deep bead 10 and second deep bead 20 are to the wind effect of dispelling of air current, reach the reinforcing wall-hanging indoor set's no wind sense air-out's effect's purpose.
In other embodiments, the wind-dispersing holes on the first wind deflector 10 and/or the second wind deflector 20 are tapered in the penetrating direction, so that the inner end aperture of the wind-dispersing holes is larger, which is beneficial for more wind-out airflow to pass through, so as to avoid larger noise caused by the wind-out airflow directly impacting the windward side of the first wind deflector 10 and/or the second wind deflector 20; the inner end aperture of the air dispersing hole is smaller, which is favorable for reducing the wind speed of the air outlet flow and enhancing the air outlet effect without wind sense.
Of course, the shape of the air vent is not limited to this, and the air vent may be a round hole or a square hole.
Referring to fig. 4, according to any of the above embodiments, in order to facilitate the air-out airflow to be guided into the air-diffusing holes on the first air-blocking plate 10 and the second air-blocking plate 20, the inner ends of the air-diffusing holes on the first air-blocking plate 10 and the second air-blocking plate 20 are all arranged in an arc-shaped tapered shape from inside to outside, so that the inner ends of the air-diffusing holes form an arc-shaped guiding opening for guiding part of the air-out airflow into the air-diffusing holes.
With continued reference to fig. 4, further, in order to facilitate guiding the air flow out of the air-diffusing holes, the outer ends of the air-diffusing holes on the first air deflector 10 and the second air deflector 20 are respectively provided with arc-shaped flaring from inside to outside. The arrangement is that the outer end of the air dispersing hole forms an arc flaring which reduces the resistance of air flow on one hand and is beneficial to rapidly diffusing the air flow passing through the air dispersing hole; on the other hand, part of the airflow diffuses along the arc-shaped flaring to the lee surface of the second wind deflector 20 of the first wind deflector 10 to balance the temperature difference between the two surfaces of the first wind deflector 10 and the temperature difference between the two surfaces of the second wind deflector 20, so as to avoid generating condensed water on the lee surface of the first wind deflector 10 or the second wind deflector 20.
Referring to fig. 4, it is considered that if the air-diffusing hole penetrates the second wind deflector 20 perpendicularly to the plate surface of the first wind deflector 10, the air-diffusing flow diffuses immediately in front of the first wind deflector 10 after passing through the air-diffusing hole on the first wind deflector 10, and the diffusion range is narrower.
Therefore, in this embodiment, based on any one of the above embodiments, the air-diffusing holes on the first wind deflector 10 are disposed obliquely upward from the windward side of the first wind deflector 10 to the through direction of the air-out side thereof. The arrangement is that after the air-out airflow passes through the air-dispersing holes on the first wind deflector 10, the air-out airflow is deflected upwards along the through direction of the air-dispersing holes on the first wind deflector 10, the air-out angle is wider, and the upwards-blown distance is larger under the inertia action of the upward flowing of the air-out airflow, so that the windless air-out range of the first wind deflector 10 is increased.
Similarly, it is considered that if the air-diffusing hole penetrates the second wind deflector 20 perpendicularly to the plate surface of the second wind deflector 20, the air-out flow diffuses immediately on the front side of the second wind deflector 20 after passing through the air-diffusing hole in the second wind deflector 20, and the diffusion range is narrow.
Therefore, in the present embodiment, based on the above embodiment, the air-diffusing holes on the second wind deflector 20 are disposed obliquely downward from the windward side of the second wind deflector 20 to the through direction of the air-out side thereof. The arrangement is such that the air-out air flow is blown out downwards along the through direction of the air-out holes on the second wind shield 20 after passing through the air-out holes on the second wind shield 20, the air-out angle is wider, and the downward blowing-out distance is larger under the inertia action of the downward flowing of the air-out air flow, thereby being beneficial to enlarging the windless air-out range of the first wind shield 10.
Therefore, the air dispersing holes on the first wind deflector 10 are arranged in an upward inclined manner from the windward side of the first wind deflector 10 to the air outlet side of the first wind deflector, and the air dispersing holes on the second wind deflector 20 are arranged in a downward inclined manner from the windward side of the second wind deflector 20 to the air outlet side of the second wind deflector, so that the wall-mounted indoor unit can be realized, and a wider windless air outlet range can be realized.
Referring to fig. 5, in this embodiment, in order to effectively guide the air flow of the wind turbine 300 to the air outlet, a volute 400 is disposed in the housing 100, the volute 400 has an air outlet duct 410 communicated with the air outlet, a baffle 30 is disposed in the air outlet duct 410 of the volute 400, and the baffle 30 is rotatably connected with the volute 400.
The rotation installation mode of the deflector 30 may be either pivot or hinge, and the air flow passing through the air outlet channel, that is, the air outlet volume of the air outlet, may be adjusted by adjusting the rotation angle of the deflector 30.
