The invention provides a wall-mounted air conditioner indoor unit and an air conditioner comprising the same.
Referring to fig. 1 and 2, in a first embodiment of a wall-mounted indoor unit of an air conditioner, the wall-mounted indoor unit of an air conditioner includes a casing 100, a first wind guard 10, and a driving device; the casing 100 includes a face shell 110, and an air outlet 112 is formed at a lower end of the face shell 110; the first wind deflector 10 is arranged at the air outlet 112, and a plurality of air dispersing holes 3 are arranged on the surface of the first wind deflector 10 in a penetrating manner; the driving device connects the housing 100 and the first wind deflector 10 to drive the first wind deflector 10 to move away from or close to the air outlet 112 toward the air outlet 112.
The casing 100 includes the backshell, the backshell encloses with the face-piece 110 and closes the cavity that forms the installation that supplies heat exchanger 1 and wind channel subassembly 2, and the top of face-piece 110 has air intake 111, when the machine during operation in the wall-hanging air conditioning, indoor air current gets into from air intake 111, after the heat exchanger 1 heat transfer, leads to the air outlet 112 through wind channel subassembly 2 and sees off.
The first wind deflector 10 is disposed at the air outlet 112, and the driving device drives the first wind deflector 10 to move towards the air outlet 112 away from or close to the air outlet 112, that is, the driving device drives the first wind deflector 10 to linearly move along the air outlet direction of the air outlet 112 to be away from the air outlet 112, or linearly move along the opposite direction of the air outlet 112 to be close to the air outlet 112.
Referring to fig. 3 and 4, when the wall-mounted air conditioner indoor unit operates, the driving device drives the first wind blocking plate 10 to be away from the air outlet 112, the first wind blocking plate 10 is opposite to the air outlet 112, and the airflow blown out from the air duct assembly 2 forms three airflows at the air outlet 112, wherein a first airflow (shown as I in the figure) is blown out from the air dispersing hole 3 on the first wind blocking plate 10, and the wind speed of the first airflow is reduced and dispersed to be soft, so that a user cannot feel wind, and a non-wind-sensing air outlet effect of the wall-mounted air conditioner indoor unit is achieved; a second air flow (as shown in fig. II) is directly blown out from a lower gap between the lower edge of the air outlet 112 and the lower edge of the first wind deflector 10, and the second air flow is not blown to the user because the lower gap faces the wall of the wall-mounted air conditioner indoor unit; the third air flow (as shown in fig. III) is blown out from the upper gap between the upper edge of the air outlet 112 and the upper edge of the first air deflector 10, and because the upper gap faces the wall top, the third air flow will not directly blow to the user. When the wall-mounted air conditioner indoor unit works, the driving device drives the first wind shield 10 to be close to the air outlet 112, and the first wind shield 10 covers the air outlet 112.
The shape and arrangement of the air dispersing holes 3 are not specifically limited, but it should be noted that a plurality of air dispersing holes 3 are uniformly arranged on the surface of the first wind screen 10 to ensure that the air dispersing of the first wind screen 10 is uniform, and the conditions of local wind absence or local wind dispersing over-high wind speed and the like are avoided.
As for the driving means, it may be a slide bar mechanism or a push bar mechanism, and it is only required that the driving means can drive the first wind deflector 10 to move linearly away from or close to the wind outlet 112. Details will be described later.
According to the technical scheme, the plurality of air dispersing holes 3 are formed in the plate surface of the first air baffle 10 in a penetrating mode, the first air baffle 10 is arranged at the air outlet 112, the driving device is used for driving the first air baffle 10 to move away from or close to the air outlet 112 at the air outlet 112, so that when the wall-mounted air-conditioning indoor unit works, air flow blown out of the wall-mounted air-conditioning indoor unit is blown out from the air dispersing holes 3 in the first air baffle 10, the air flow speed is reduced and is dispersed to be soft, a user cannot feel the air, the no-wind-feeling air outlet effect of the wall-mounted air-conditioning indoor unit is achieved, and the comfort degree of using the wall-mounted air-conditioning indoor unit is improved.
Referring to fig. 3, the driving device has various structures, and in this embodiment, the driving device includes a push rod 30 disposed inside the housing 100, a first motor, and a gear connected to the first motor, an inner end of the push rod 30 is slidably connected to the housing 100, an outer end of the push rod is connected to the first wind deflector 10, and the push rod 30 is provided with a rack engaged with the gear.
Specifically, a sleeve ring or a slideway is arranged in the casing 100, the inner end of the push rod 30 is connected with the casing 100 in a sliding manner through the sleeve ring or the slideway, and in order to prevent the push rod 30 from slipping off the sleeve ring, the inner end of the push rod 30 and the sleeve ring are provided with an adaptive anti-disengaging structure, such as an anti-disengaging buckle or an anti-disengaging self-locking elastic sheet. The rack is arranged in the middle of the push rod 30, and the rack is engaged with the gear so as to drive the push rod 30 to slide back and forth through the first motor, thereby driving the first wind deflector 10 to move away from or close to the air outlet 112 at the air outlet 112.
Of course, the driving means is not limited to this structure. In other embodiments, the driving device may further include a return spring at an inner end of the push rod 30, one end of the return spring is connected to the inner end of the push rod 30, and the other end of the return spring is connected to the housing 100, so as to assist the push rod 30 to reciprocate by using the elasticity of the return spring, thereby reducing the power consumption of the first motor.
Referring to fig. 5 and 6, in the present embodiment, in order to change the wind outlet direction of the wind outlet 112 by changing the inclination angle of the first wind deflector 10, the first wind deflector 10 is rotatably connected to the outer end of the push rod 30. For example, when the first wind deflector 10 is away from the air outlet 112, the first wind deflector 10 deflects around the outer end of the push rod 30 under the action of its own gravity when the first wind deflector 10 is hinged to the outer end of the push rod 30, so that the size of the upper gap or the lower gap between the air outlet 112 and the first wind deflector 10 can be changed, and the air outlet direction of the air outlet 112 can be changed.
Referring to fig. 7 and 8, in consideration of the uncertainty that the first wind deflector 10 will deflect around the outer end of the push rod 30 due to its own weight, a motor is preferably used to control the deflection of the first wind deflector 10. Therefore, in this embodiment, the outer end of the push rod 30 is provided with the mounting seat 40, the wall-mounted air conditioning indoor unit is provided with the second motor on the mounting seat 40, the inner panel surface of the first wind deflector 10 is provided with the lug 11, and the lug 11 is connected with the driving shaft of the second motor.
Specifically, the mounting seat 40 has a cavity, the second motor is mounted in the cavity, and the lug 11 is provided with a rotating shaft, the rotating shaft extends into the cavity and is connected with a driving shaft of the second motor, so that the second motor is used to drive the first wind deflector 10 to deflect, thereby effectively controlling the wind outlet direction of the wind outlet 112. Obviously, in other embodiments, a shaft hole may be provided on the lug 11, and the driving shaft of the second motor may be directly mounted in the shaft hole.
When the wall-mounted air conditioner indoor unit heats, as shown in fig. 6, the second motor is used for driving the first wind shield 10 to deflect upwards, the outlet airflow of the wall-mounted air conditioner indoor unit forms two airflows at the air outlet 112, the first airflow is larger than the second airflow, and the first airflow directly blows downwards to the indoor bottom layer, so that a foot warming effect is achieved, and the heating effect is better.
When the wall-mounted air conditioner indoor unit is used for refrigerating, as shown in fig. 8, the second motor is used for driving the first wind shield 10 to deflect downwards, the air outlet flow of the wall-mounted air conditioner indoor unit forms two air flows at the air outlet 112, wherein the first air flow flows towards the inner plate surface of the first wind shield 10, part of the first air flow is blown upwards and then naturally subsides, the refrigerating effect is good, the air is prevented from directly blowing towards a user, the other part of the first air flow flows through the air dispersing holes 3 in the first wind shield 10 to diffuse downwards, the part of the first air flow is mixed with the second air flow on the outer plate surface of the first wind shield 10 in a cross mode, and therefore the second air flow is dispersed to be soft, and the air outlet effect of the wall-mounted air conditioner indoor unit without wind is better.
Referring to fig. 9, in the second embodiment of the present invention, the difference from the first embodiment is that the casing 100 includes a lower volute casing 120, the wall-mounted indoor unit of an air conditioner is provided with a second air baffle 20 on an inner side surface of the lower volute casing 120, and the second air baffle 20 is rotatably connected to the lower volute casing 120, so that the second air baffle 20 is used to weaken an outlet airflow blown out from a gap at a lower edge of the air outlet 112, thereby achieving a better non-wind effect.
Specifically, both ends of the second wind deflector 20 have a rotating shaft, the lower volute 120 has a shaft hole for the rotating shaft to be inserted, and the lower volute 120 has a third motor connected to the rotating shaft to drive the second wind deflector 20 to turn.
Referring to fig. 10, after the first wind deflector 10 is opened, the second wind deflector 20 is turned outwards, and a portion of the airflow at the stop of the second wind deflector 20 flows downwards, so as to reduce the wind sensation of the outlet airflow blown out from the gap at the lower edge of the air outlet 112.
Referring to fig. 11, after the first wind deflector 10 is turned upwards at the same time, the second wind deflector 20 is turned 180 ° outwards, the first wind deflector 10 and the second wind deflector 20 enclose the air supply duct of the air outlet 112, so that the air supply distance of the air outlet is extended, and the warm heat is favorably supplied to the indoor bottom layer to achieve the foot warming effect.
Referring to fig. 11, after the first wind deflector 10 is turned downward, the second wind deflector 20 is turned 180 ° outward, the first wind deflector 10 and the second wind deflector 20 enclose the air supply duct of the air outlet 112, and the air supply distance of the air outlet is extended, so as to facilitate the realization of rapid cooling at the initial stage of cooling.
Referring to fig. 12, in the present embodiment, on the premise of ensuring no wind-induced air output of the air conditioner, the air-diffusing range and the air-diffusing effect of the air conditioner are improved, and a plurality of air-diffusing holes 3 are formed through the second air baffle 20. And part of outlet air flow of the wall-mounted air conditioner indoor unit is diffused downwards through the air dispersing holes 3 on the second air baffle 20, and the air speed of the part of air flow is reduced, so that no wind feeling can be realized.
Referring to fig. 12 again, in the present embodiment, in order to reduce the space occupied by the second wind deflector 20 in the wind tunnel, an accommodating groove for accommodating the second wind deflector 20 is disposed on the inner side surface of the lower volute casing 120, so that when the second wind deflector 20 is not needed, the second wind deflector 20 is accommodated in the accommodating groove.
Referring to fig. 12, in the present embodiment, in order to increase the non-wind-induced wind-dispersing range of the wall-mounted air conditioner indoor unit, the inner plate of the first wind-shielding plate 10 is configured in a concave arc shape, so that the outlet air current can be diffused along the inner plate of the first wind-shielding plate 10 to both sides, and the outlet air current is diffused from the wind-dispersing holes 3 of the first wind-shielding plate 10 in a hemispherical shape. Therefore, the inner plate surface of the first wind shield 10 is arranged in a concave arc shape, so that the non-wind-induction wind-dispersing range of the wall-mounted air conditioner indoor unit can be effectively enlarged.
Referring to fig. 13, it is considered that if the air dispersing holes 3 are in a straight cylinder shape and the first wind deflector 10 penetrates through the straight cylinder shape, when the wall-mounted air conditioner indoor unit cools, airflow passes through the air dispersing holes 3 and then directly blows to the outside, and the airflow does not pass through the outer plate surface of the first wind deflector 10, so that the temperature difference between the inside and the outside of the first wind deflector 10 is large, and water vapor in the air is easily condensed into condensed water on the outer plate surface of the first wind deflector 10.
Therefore, in this embodiment, to avoid the above situation, the outer end of the air dispersing hole 3 is arranged in an arc flaring shape from inside to outside. When the air current blows out from the interior face wind scattering hole 3 of first deep bead 10, the air current is gently outwards diffused to the outer face of first deep bead 10 at the flared end of wind scattering hole 3 to this temperature difference of the inside and outside both sides of balanced first deep bead 10 avoids being formed with the formation comdenstion water at the outer panel face of first deep bead 10.
Referring to fig. 14, in other embodiments, in order to achieve a better non-wind effect, the penetrating direction of the wind-dispersing holes 3 is curved, so that the first wind-blocking plate 10 or the second wind-blocking plate 20 penetrates the wind-dispersing holes 3 in a curved shape, and compared with the straight-tube-shaped wind-dispersing holes 3, in this embodiment, the wind resistance of the curved wind-dispersing holes 3 is larger, so as to more effectively reduce the wind speed of the airflow at the wind outlet 112, thereby achieving a better non-wind effect.
Referring to fig. 14, in the present embodiment, considering that the distance between two adjacent air dissipating holes 3 is not too large, otherwise, condensed water may be generated on the outer panel surface of the first wind deflector 10, so that the distance between the centers of two adjacent air dissipating holes 3 is limited to 5mm to 10mm.
If the center distance between two adjacent air dispersing holes 3 is less than 5mm, the strength of the first wind shield 10 is poor and deformation is easy to occur due to the over-dense air dispersing holes 3; if the center distance between two adjacent air dispersing holes 3 is larger than 10mm, the air dispersing effect and the condensed water preventing effect are poor because the air dispersing holes 3 are too sparse. Therefore, the center-to-center distance between two adjacent air dispersing holes 3 is limited to 5 mm-10 mm, specifically 6.5mm, 8.5mm or 9.5 mm.
Referring to fig. 4, in order to ensure that the first baffle has a better air diffusion effect, the aperture of the air diffusion hole 3 is 2mm to 5mm, such as 2.5mm, 3.5mm, or 4.5 mm. If the aperture of the air dispersing hole 3 is smaller than 2mm, the air resistance is large due to the small air dispersing hole 3, and the outlet air flow is difficult to diffuse out through the air dispersing hole 3; if the aperture of the air dispersing hole 3 is larger than 5mm, the air resistance is smaller due to the overlarge air dispersing hole 3, the air outlet air flow still has larger air speed after passing through the air dispersing hole 3, and the realization of non-wind-sensing air outlet of the indoor unit of the wall-mounted air conditioner is not facilitated.
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.
