The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Based on the problem that condensation is easily generated on the outer surface of an air deflector of the existing air conditioner pointed out by the background art, the invention provides the air deflector for the air conditioner and the air conditioner, and aims to avoid the condensation generated on the air deflector.
Specifically, the air conditioner of the present invention includes an outdoor unit and an indoor unit, the outdoor unit mainly includes a compressor, a condenser, a gas-liquid separator, a four-way reversing valve, and other components, as shown in fig. 1 and 2, the indoor unit mainly includes a casing 1, and a heat exchanger (not shown in the figure) and a fan (not shown in the figure) disposed in the casing 1, an air outlet 11 is disposed on the casing 1, an air deflector 2 is disposed at the air outlet 11, the air deflector 2 is rotatably connected to the casing 1, and an air outlet direction can be changed by adjusting a rotation angle of the air deflector 2.
As can be seen from the background art, when the air conditioner operates in a cooling mode, the temperature of the air deflector 2 is relatively low due to the influence of cold air, however, the indoor air temperature is relatively high, when the hot air contacts the low-temperature air deflector 2, moisture in the hot air is condensed, and condensation is generated on the outer surface of the air deflector 2, for this reason, as shown in fig. 1 and 2, the air deflector 2 of the present invention is provided with the inducing hole 21, the air inlet end 211 of the inducing hole 21 is located on the outer surface of the air deflector 2, the air outlet end 212 of the inducing hole 21 is located on the inner surface of the air deflector 2, and the inducing hole 21 is inclined toward the front end of the air deflector 2 from the air inlet end 211 to the air outlet end 212, so that the air outside the air deflector 2 can be induced to the inner side of the air deflector 2 and thus mixed with the air in the air outlet 11 when the air conditioner operates.
As shown in fig. 1, the air guiding plate 2 is in a closed state, a surface of the air guiding plate 2 exposed to the outside is an outer surface of the air guiding plate 2, that is, the surface is seen to be an inner surface of the air guiding plate 2 opposite to the outer surface, and a front end of the air guiding plate 2 refers to an end close to an outermost edge of the casing 1.
As shown in fig. 2, when the air conditioner is operated in a cooling mode, the hot air outside the air deflector 2 can flow to the inside of the air deflector 2 through the inducing hole 21 and then mix with the cold air in the air outlet 11, specifically, because the air flow rate in the air outlet 11 is relatively high when the air conditioner is operated, so that the air pressure inside the air deflector 2 is reduced, at this time, the air pressure outside the air deflector 2 is higher than the air pressure inside the air deflector 2, the hot air outside the air deflector 2 is sucked to the inside of the air deflector 2 under the action of the atmospheric pressure, or the hot air outside the air deflector 2 is induced to the inside of the air deflector 2 and then mixes with the cold air in the air outlet 11 to form mixed air, so as to raise the temperature of the air in the air outlet 11, so that the temperature of the air deflector 2 is not so low, that the temperature of the air deflector 2 is equivalent to raise the temperature of the air deflector 2, the temperature of the air deflector 2 is high, so that the moisture in the air is not condensed, and the condensation on the outer surface of the air deflector 2 can be avoided.
The inducing holes 21 may be circular holes, square holes, or strip-shaped holes, and further, one row of inducing holes 21 may be provided in the width direction of the air deflector 2, and multiple rows of inducing holes 21 may also be provided, and the adjustment and change of the specific shape and the specific arrangement of the inducing holes 21 are not departing from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
It should be noted that, compared with the air conditioner air deflector disclosed in the patent document with publication number CN209991595U, the present invention adopts a completely different technical means to solve the problem that condensation is easily generated on the outer surface of the air deflector 2, and the inventive concept is completely different, specifically, the patent with publication number CN209991595U is that cold air inside the air deflector is shunted to the outer side of the air deflector to block the hot air from contacting with the air deflector, so that the moisture in the hot air can be prevented from being condensed, and further the condensation is prevented from being generated on the outer surface of the air deflector; in the invention, the hot air outside the air deflector 2 is induced to the inner side of the air deflector 2 and is mixed with the cold air in the air outlet 11 to form mixed air, the temperature of the gas at the air outlet 11 is raised, so that the temperature of the air deflector 2 is prevented from being too low, the moisture in the hot air cannot be condensed by the air deflector 2, and further condensation on the outer surface of the air deflector 2 is avoided, in other words, the air deflector 2 can be regarded as a condenser, the patent with the publication of CN209991595U is to prevent the moisture in the hot air from being condensed by cutting off the contact between the hot air and the air deflector 2 (condenser), but the invention directly enables the air deflector 2 not to be a condenser, namely 'directly eliminating the source of condensation', and the moisture in the hot air cannot be condensed naturally without the condenser.
In addition, it should be noted that, compared with the air-conditioning air deflector disclosed in the patent document with publication number CN209991595U, the air deflector 2 of the present invention can obtain better technical effects, firstly, the air deflector 2 of the present invention can more effectively avoid the generation of condensation, specifically, as can be seen from the comparison of the above inventive concepts, the present invention "directly eliminates the source of condensation", and the patent with publication number CN209991595U avoids the contact with the air deflector (the source of condensation), in other words, one directly eliminates the "source of condensation", and one avoids the contact with the "source of condensation", compared with both, the way of directly eliminating the "source of condensation" is more effective, and the effect is better; secondly, the direct blowing of cold air at the air outlet 11 can be avoided, and specifically, the temperature of the air at the air outlet 11 is improved by mixing hot air at the outer side of the air deflector 2 with cold air at the inner side of the air deflector 2, so that the air outlet temperature is more suitable, the air is more comfortable to blow on the body of a user, and the user experience is better; however, the patent with publication number CN209991595U is just opposite to the present invention, and the patent directly branches the cold air inside the air guiding plate to the outside of the air guiding plate, so that the cold air is easier to directly blow on the user, and the user feels uncomfortable.
In summary, compared with the patent with publication number CN209991595U, the present invention can solve the technical problems in the patent by more effective technical means, and can obtain more significant technical effects than the patent.
Preferably, as shown in fig. 3, an angle a between the axis of the induction hole 21 and the thickness direction of the air deflector 2 is 60 to 70 degrees. The inventor researches and discovers that although the air deflector 2 of the air conditioner can have a plurality of opening angles, the common opening angle of the air deflector 2 of the prior air conditioner is generally 20 degrees to 30 degrees, namely the included angle b between the air deflector 2 and the horizontal plane is generally 20 degrees to 30 degrees, if the common opening angle of the air deflector 2 of the air conditioner is 30 degrees, namely the included angle b is 30 degrees, the included angle a between the axis of the inducing hole 21 and the thickness direction of the air deflector 2 is set to be 60 degrees, when the air deflector 2 is opened to 30 degrees, because the sum of the included angle a and the included angle b is exactly 90 degrees, at the moment, the inducing hole 21 is in a horizontal state, so that the air outside the air deflector 2 is more easily induced to the inner side of the air deflector 2, and the condensation prevention effect is better. That is, in practical application, a specific value of an included angle a between the axis of the inducing hole 21 and the thickness direction of the air deflector 2 may be set according to a specific value of a common opening angle b of the air deflector 2 of the air conditioner, and a sum of the included angle a and the included angle b is equal to 90 degrees, so that the inducing hole 21 may be in a horizontal state when the air conditioner is in operation, in which case, air outside the air deflector 2 is more easily induced to the inner side of the air deflector 2, and the anti-condensation effect is better.
Preferably, as shown in fig. 2 and 3, the front end of the air deflector 2 is provided with an air inducing structure 22 extending obliquely toward the inner side of the air deflector 2, so that the air blown out from the outlet 11 can flow in the horizontal direction when the air deflector 2 rotates to the set operating position. Through setting up induced air structure 22, can prevent that the wind that air outlet 11 blew out from directly blowing down on one's body to the user, that is to say, when aviation baffle 2 rotated to setting for the operating position, induced air structure 22 was horizontal state roughly for the wind that blows out from air outlet 11 can flow along the horizontal direction, prevents that wind from directly blowing down on one's body to the user, promotes user's use and experiences. Further preferably, the inducing hole 21 is approximately parallel to the air inducing structure 22, so that the inducing hole 21 is approximately horizontal when the air deflector 2 rotates to the set working position. That is, when the air conditioner is operated, the air guide plate 2 rotates to the set operation position to make the air inducing structure 22 in a substantially horizontal state, so that the wind blown out from the air outlet 11 can flow in a horizontal direction, and at the same time, the inducing hole 21 is also in a substantially horizontal state, so that the air outside the air guide plate 2 is more easily induced to the inner side of the air guide plate 2, and the condensation preventing effect is better.
Preferably, as shown in fig. 2, the housing 1 is provided with a gas speed increasing structure 12, and the gas speed increasing structure 12 is configured to increase the flow velocity of the gas at the air outlet 11 by reducing the cross-sectional area of the air outlet channel at the air outlet 11 when the air deflector 2 rotates to the set working position. When the air deflector 2 rotates to a set working position, the vertical distance between the gas speed-increasing structure 12 and the air deflector 2 is obviously smaller than the vertical distance between other positions of the shell 1 and the air deflector 2, the cross-sectional area of an air outlet channel at the position is minimum, when gas flows through the position, the gas can be accelerated, the faster the flow rate of the gas is, the lower the air pressure at the inner side of the air deflector 2 is, the stronger the suction force is, more hot air positioned at the outer side of the air deflector 2 can be attracted to the inner side of the air deflector 2, the condensation prevention effect is improved, in addition, the faster the flow speed of the gas is, the faster the propagation speed is, the longer the propagation distance is, and the indoor temperature can be reduced as soon as possible. Further preferably, the inducing hole 21 is disposed near a position of the wind deflector 2 corresponding to the gas accelerating structure 12. It should be noted that the position where the air deflector 2 corresponds to the gas speed increasing structure 12 refers to a position where the distance between the air deflector 2 and the gas speed increasing structure 12 is shortest, the flowing speed of the gas in the air outlet channel corresponding to the position is fastest, and the inducing hole 21 is arranged close to the position, so that more hot air outside the air deflector 2 can be induced to the inner side of the air deflector 2, and the condensation preventing effect is improved.
Preferably, as shown in fig. 4 and 5, the air inlet end 211 and the air outlet end 212 of the induction hole 21 are arranged in a staggered manner in the width direction of the air deflector 2. Specifically, as shown in fig. 5, the dotted line in the drawing indicates the thickness direction of the air guide plate 2, the right side line of the air inlet end 211 coincides with the left dotted line, the left side line of the air outlet end 212 coincides with the right dotted line, and the air inlet end 211 is located on the left side and the air outlet end 212 is located on the right side in the width direction of the air guide plate 2, and there is no overlapping portion therebetween.
It should be noted that, for convenience of understanding, a certain distance is provided between the right side line of the air inlet end 211 and the left side line of the air outlet end 212 shown in fig. 5 in the width direction of the air deflector 2, that is, the distance L shown in the figure is greater than 0, and actually, when the distance L is equal to 0, that is, when the right side line of the air inlet end 211 coincides with the left side line of the air outlet end 212, the user can be prevented from seeing the internal structure of the air conditioner through the induction hole 21, that is, the distance L is only required to be greater than or equal to 0.
Preferably, as shown in fig. 6, two rows of the inducing holes 21 are arranged along the width direction of the wind deflector 2, and each inducing hole 21 is arranged in a long strip shape along the length direction of the wind deflector 2. A plurality of elongated attracting holes 21 are provided in each row, but it is needless to say that a plurality of elongated attracting holes 21 in the same row may be directly pulled through to form a single elongated attracting hole 21. The inventors verified through repeated experiments that the effect of preventing condensation is very significant when the width of the induction hole 21 is 2mm to 10 mm.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
