Composite air guide blade structure and air conditioner indoor unit

Technical Field

The present invention relates to the technical field of air conditioners, and in particular to a composite air guide blade structure and an air conditioner indoor unit.

Background technique

When the air conditioner is cooling, condensation is likely to form on the surface of the indoor unit, affecting the user's comfort experience.

The existing methods for preventing condensation in indoor units of air conditioners are roughly as follows:

(1) Insulation is achieved by pasting cotton on the panel frame to prevent condensation. This method has the following disadvantages: complex process, high cost, and poor effect.

(2) By flocking on the windward side of the air guide strip, the velvet cloth absorbs water to alleviate the dripping of condensation water. This method has the following disadvantages: it is not beautiful, has many and complicated processes, is costly, and has a short time effect.

(3) The air sweeping blades are controlled by a program to perform periodic air sweeping. The principle is to control the rotation time and speed of the air guide plate by a program to avoid condensation at the intersection of the cold and hot air flows of the air conditioner and achieve the purpose of removing condensation. This solution has the following disadvantages: poor comfort, high cost, and insignificant effect.

Summary of the invention

The problem solved by the present invention is that the existing solution for preventing condensation in an indoor unit of an air conditioner has the problems of complex process, high cost and insignificant anti-condensation effect.

In order to solve the above problems, the present invention provides a composite air guide blade structure and an air conditioner indoor unit.

According to one aspect of the present invention, a composite wind guide blade structure 1 is provided, comprising: a main wind blade structure 11, the main wind blade structure 11 comprising: a main wind blade 111, the outer surface of the main wind blade 111 is provided with an auxiliary wing structure 12, the auxiliary wing structure 12 guides part of the outgoing wind to blow toward the condensation-prone area on the outer surface of the main wind blade 111.

By setting up the auxiliary wing structure 12, the auxiliary wing structure 12 guides part of the outlet air (cold air) blown out from the main wind blade 111 to blow toward the condensation-prone area on the outer surface of the main wind blade structure 11. Generally speaking, the cold air blown out is guided to blow toward the bottom of the main wind blade 111, so that the temperature on the inside and outside of the main wind blade 111 is kept consistent, and the hot air at the bottom of the outer side is prevented from reaching the dew point temperature for condensation. In principle, the occurrence of condensation water is eliminated, and a better anti-condensation effect is achieved. At the same time, by setting up the auxiliary wing structure 12 on the main wind blade 111, the wind field effect is also improved. The flow direction of the wind flowing out along the gap between the main wind blade 111 and the auxiliary wing structure 12 of the composite wind guide blade structure 1 is smoother, and the turbulence noise caused by the blowing is also reduced.

In an embodiment of the present invention, the main airflow blade structure 11 includes: a main airflow blade 111 and a support frame 112 . The support frame 112 is disposed at both ends of the main airflow blade 111 to support the main airflow blade 111 .

In one embodiment of the present invention, the angle α between the auxiliary wing structure 12 and the main wind guiding blade 111 satisfies: 0°≤α≤60°.

In one embodiment of the present invention, the distance h between the top of the auxiliary wing structure 12 and the top of the main wind blade 111 satisfies: -10mm≤h≤30mm, where the negative sign in front of the value indicates that the top of the auxiliary wing structure 12 is higher than the top of the main wind blade 111.

In one embodiment of the present invention, the distance s between the center of the auxiliary wing structure 12 and the main wind blade 111 satisfies: 2 mm-10 mm.

In addition, the blowing comfort and turbulence noise can also be regulated. Experimental tests have shown that different angle values α will have different guiding effects on the airflow. When the horizontal and vertical distances (horizontal distance s, vertical distance h) of the auxiliary wing structure 12 from the main wind blade 111 are different, the decondensation effect, blowing comfort and blowing noise it brings will also be different. The angle value α is tested to be between 0° and 60°, and the anti-condensation effect is better; the distance h between the top of the auxiliary wing structure 12 and the top of the main wind blade 111 is the longitudinal distance, and the anti-condensation effect is better when the longitudinal distance h is between -10 and 30 mm, where the negative sign in front of the value indicates that the top of the auxiliary wing structure 12 is higher than the top of the main wind blade 111, and correspondingly, the positive value indicates that the top of the auxiliary wing structure 12 is lower than the top of the main wind blade 111; the distance s between the center of the auxiliary wing structure 12 and the main wind blade 111 is between 2 mm and 10 mm, and the anti-condensation effect is better. The above three groups of parameters can be met at the same time, or only one of the conditions can be met.

In one embodiment of the present invention, the anti-condensation effect is adjusted by adjusting at least one of the cross-sectional shape of the auxiliary wing structure 12, the cross-sectional thickness of the auxiliary wing structure 12, the distance between the top of the auxiliary wing structure 12 and the top of the main wind blade 111, and the distance between the center of the auxiliary wing structure 12 and the main wind blade 111.

The cross-sectional shape, cross-sectional thickness and the distance between the auxiliary wing structure 12 and the surface where the main wind blade 111 is located (here, the lateral distance) of the auxiliary wing structure 12 are related to the anti-condensation effect and can be optimized and set through experiments or simulations. The distance between the auxiliary wing structure 12 and the surface where the main wind blade 111 is located is the lateral distance. In this embodiment, the cross-sectional shape, cross-sectional thickness and the lateral distance between the auxiliary wing structure 12 and the surface where the main wind blade 111 is located are changed to achieve the regulation of the anti-condensation effect, blowing comfort and turbulence noise. According to actual needs, the cross-sectional shape, cross-sectional thickness and the lateral distance of the auxiliary wing structure 12 can be regulated by means of experiments or simulations, so as to achieve the optimal anti-condensation effect or the comprehensive optimality of two or three of the anti-condensation effect, blowing comfort and turbulence noise.

By using reinforcing ribs as the connecting parts 13, it helps to ensure the strength and rigidity of the connection between the auxiliary wing structure 12 and the main wind blade 111, and can overcome the problems such as distortion and deformation caused by uneven stress due to the difference in wall thickness between the main wind blade 111 and the auxiliary wing structure 12 during the manufacturing process.

Detailed ways

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example

In a first exemplary embodiment of the present invention, a composite wind guide blade structure is provided.

FIG. 1 is a perspective schematic diagram of a composite air guide blade structure according to an embodiment of the present invention.

As shown in Figure 1, the composite wind guide blade structure 1 of the present invention includes: a main wind blade structure 11, the main wind blade structure 11 includes a main wind blade 111, and the outer surface of the main wind blade 111 is provided with an auxiliary wing structure 12, and the auxiliary wing structure 12 guides the air outlet direction of the guiding part to blow toward the condensation-prone area on the outer surface of the main wind blade 111.

It should be noted that in FIG1 , the details of the main wind blade structure 11 are simplified, such as omitting the corrugated groove, and FIG2 illustrates the structure of the corrugated groove 1111 in the main wind blade structure 11. Throughout the text, the "inside" and "outside" described are relative to the wind direction. The "inside" corresponds to the "rear" along the "front and back" direction, and the "outside" corresponds to the "front" along the "front and back" direction.

Fig. 2 is a schematic diagram of the principle of preventing condensation of a composite wind guide blade structure according to an embodiment of the present invention. Fig. 7 is a comparison diagram of wind field simulation effects between the composite wind guide blade structure of the embodiment of the present invention and the existing wind guide blade, wherein (a) is a wind field simulation effect diagram of the existing wind guide blade, and (b) is a wind field simulation effect diagram of the composite wind guide blade structure of the embodiment of the present invention.

As shown in Figure 2, by setting an auxiliary wing structure 12, the auxiliary wing structure 12 guides part of the air blown out from the main air blade 111 to blow toward the condensation-prone area on the outer surface of the main air blade 111. Generally speaking, the condensation-prone area is located at the bottom of the main air blade 111 in the main air blade structure 11, and the corrugated groove 1111 is generally set at the top of the main air blade 111. In one example, part of the cold wind is guided by the auxiliary wing structure 12 to blow toward the bottom of the main wind blade 111. The wind direction is indicated by an arrow in FIG2, so that the temperature on the inside and outside of the main wind blade 111 is kept consistent, and the hot air at the bottom of the outer side is prevented from reaching the dew point temperature for condensation. In principle, the appearance of condensation water is eliminated, and a better anti-condensation effect is achieved. At the same time, by arranging the auxiliary wing structure 12 on the main wind blade 111, the wind field effect is also improved. By comparing (a) and (b) in FIG7, it can be seen that the existing single wind guide plate without the auxiliary wing structure has a turbulence zone. By arranging the auxiliary wing structure 12 on the side where the main wind blade 111 is out of the wind, the flow direction of the wind flowing out along the gap between the main wind blade 111 and the auxiliary wing structure 12 of the composite wind guide blade structure 1 is smoother than that of a single wind guide plate, and the turbulence noise caused by the blowing is also reduced.

In one embodiment of the present invention, as shown in FIG. 1 , the main wind blade structure 11 includes: a main wind blade 111 and a support frame 112 . The support frame 112 is disposed at both ends of the main wind blade 111 for supporting the main wind blade 111 .

Fig. 3 is a schematic diagram of the setting angle and height dimensions of the auxiliary wing structure according to an embodiment of the present invention; Fig. 4 is a schematic diagram of the setting angle range of the auxiliary wing structure according to an embodiment of the present invention; Fig. 5 is a schematic diagram of the setting height range of the auxiliary wing structure according to an embodiment of the present invention; and Fig. 6 is a schematic diagram of the cross-sectional shape of the auxiliary wing structure according to an embodiment of the present invention.

In the present invention, for example, as shown in FIG3 , by adjusting at least one of the two factors, the angle α between the auxiliary wing structure 12 and the dominant wind blade 111 and the distance between the auxiliary wing structure 12 and the dominant wind blade 111, the wind field can be regulated, thereby achieving the anti-condensation effect, the blowing comfort and the regulation of the turbulence noise. Among them, the distance between the auxiliary wing structure 12 and the dominant wind blade 111 is divided into a longitudinal distance h and a lateral distance s. In FIG3 , the longitudinal distance h is indicated by the distance between the dotted lines, and the angle α between the auxiliary wing structure 12 and the dominant wind blade 111 is indicated by the angle between the tangents corresponding to the surfaces of the auxiliary wing structure 12 and the dominant wind blade 111, and the tangents are dotted lines; since the auxiliary wing structure 12 has an inclination angle relative to the dominant wind blade 111, the lateral distance s between the two is not equal everywhere, so the lateral distance can be defined with a certain position as a reference, for example, the vertical distance from the center position of the auxiliary wing structure 12 to the dominant wind blade 111 is taken as the lateral distance s, as shown by the double arrows in FIG3 . In addition, the wind field can be controlled by changing at least one of the cross-sectional shape and the cross-sectional thickness of the auxiliary wing structure 12 .

In one embodiment of the present invention, as shown in FIG. 3 and FIG. 4 , the angle α between the auxiliary wing structure 12 and the main wind blade 111 satisfies: 0°≤α≤60°. In one embodiment, the distance h between the top of the auxiliary wing structure 12 and the top of the main wind blade 111 satisfies: -10mm≤h≤30mm, wherein the negative sign in front of the value indicates that the top of the auxiliary wing structure 12 is higher than the top of the main wind blade 111. In one embodiment, the distance s between the center of the auxiliary wing structure 12 and the main wind blade 111 satisfies: 2mm-10mm.

In the present disclosure, “A and/or B” means A or B or both A and B are satisfied.

By changing at least one of the following conditions: the angle α between the auxiliary wing structure 12 and the main wind blade 111, the distance h between the top of the auxiliary wing structure 12 and the top of the main wind blade 111, and the distance s between the center of the auxiliary wing structure 12 and the main wind blade 111, the anti-condensation effect can be regulated. In addition, the blowing comfort and turbulence noise can also be regulated.

Through experimental tests, different angle values α will have different guiding effects on the airflow. When the horizontal and vertical distances of the auxiliary wing structure 12 from the main wind blade 111 are different, the decondensation effect, blowing comfort and blowing noise it brings will also be different. After testing, the angle value α is between 0° and 60°, including the endpoint value. Any angle within this range, such as 0°, 15°, 20°, 25°, 30°, 35°, 38°, 40°, 45°, 50°, 60°, etc., has a better anti-condensation effect. The distance between the top of the auxiliary wing structure 12 and the top of the main wind blade 111 is the longitudinal distance h. The longitudinal distance h has a better anti-condensation effect between -10 and 30 mm, where the negative sign in front of the value indicates that the top of the auxiliary wing structure 12 is higher than the top of the main wind blade 111, and correspondingly, the positive value indicates that the top of the auxiliary wing structure 12 is lower than the top of the main wind blade 111. The distance s between the center of the auxiliary wing structure 12 and the main wind blade 111 is between 2 mm and 10 mm, which has a better anti-condensation effect. The above three groups of parameters can be satisfied at the same time, or only one of the conditions can be satisfied.

For example, in FIG4 , three positions of the auxiliary wing structure 12 are illustrated, and the angles between the auxiliary wing structure 12 and the dominant wind blade 111 in the three positions are: α1, α2 and α3, wherein α1=0°, α2=35°, α3=60°. For example, in FIG5 , four groups of horizontal and vertical distances are illustrated, such as: h1=1.5mm, h2=10mm, h3=20mm, h4=30mm, s1=0.5mm, s2=1mm, s3=2mm, s4=5mm. The above values are only examples of optimization parameters in this embodiment. Other values of horizontal distance and vertical distance and combinations of the two can also be changed.

In one embodiment of the present invention, the cross-sectional shape and cross-sectional thickness of the auxiliary wing structure 12 and the distance between the auxiliary wing structure 12 and the surface where the main wind blade 111 is located are related to the anti-condensation effect and can be optimized through experiments or simulations.

The distance between the auxiliary wing structure 12 and the surface where the main wind blade 111 is located is the lateral distance. In this embodiment, the cross-sectional shape, cross-sectional thickness and cross-sectional distance between the auxiliary wing structure 12 and the surface where the main wind blade 111 is located are changed to achieve the regulation of the anti-condensation effect, blowing comfort and turbulence noise. According to actual needs, the cross-sectional shape, cross-sectional thickness and cross-sectional distance of the auxiliary wing structure 12 can be regulated by experimental or simulation means, so as to achieve the optimal anti-condensation effect or the comprehensive optimality of two or three of the anti-condensation effect, blowing comfort and turbulence noise.

In one embodiment of the present invention, as shown in FIG. 6 , the surface of the auxiliary wing structure 12 opposite to the main wind blade 111 has smooth guiding properties.

In one embodiment, the cross-section of the auxiliary wing structure 12 includes one or a combination of the following shapes: a quadrilateral, a triangle, a trapezoid, a polygon with more than four sides, a triangle with an arc, a quadrilateral with an arc, a trapezoid with an arc, a polygon with more than four sides with an arc, and an irregular shape.

The panel portion of the auxiliary wing structure 12 can have the same shape as the main wind blade 111, and the surface of the auxiliary wing structure 12 opposite to the main wind blade 111 has smooth guiding properties, which helps to make the wind field smooth and reduce wind noise, and achieve a better guiding effect. The cross-sectional shape of the auxiliary wing structure 12 can be various, such as a quadrilateral, such as a rectangle or other forms of quadrilaterals, a triangle, a trapezoid, a triangle with an arc, a quadrilateral with an arc, a trapezoid with an arc, etc.

In the present invention, the auxiliary wing structure 12 and the main wind blade 111 have a connection relationship, and the connection relationship between the two can be a fixed connection, and the relative position of the two is fixed and cannot be changed. For example, the auxiliary wing structure 12 and the main wind blade structure 11 can be fixedly connected by an integral molding method or other detachable assembly methods can be used to fix the two. For example, the auxiliary wing structure 12 is assembled with the main wind blade structure 11 by a hook; it can also be a non-fixed connection, and the relative position relationship between the two can be changed. For example, the auxiliary wing structure 12 can rotate relative to the main wind blade 111.

For example, in one embodiment of the present invention, the connection relationship between the auxiliary wing structure 12 and the main wind blade 111 is a fixed connection. Referring to FIG. 1 , the auxiliary wing structure 12 is fixed to the wind outlet side of the main wind blade 111 through a connector 13 .

In one embodiment of the present invention, the connecting member 13 is a reinforcing rib. The reinforcing rib includes a first reinforcing rib 131 and a second reinforcing rib 132, wherein the second reinforcing rib 132 is connected to both sides of the edge of the auxiliary wing structure 12 and the main wind blade 111, and the first reinforcing rib 131 is connected to the non-edge position of the auxiliary wing structure 12 and the main wind blade 111, for example, the middle of the auxiliary wing structure 12 is connected to the middle of the main wind blade 111 through the first reinforcing rib 131.

By using reinforcing ribs as the connecting parts 13, it helps to ensure the strength and rigidity of the connection between the auxiliary wing structure 12 and the main wind blade 111, and can overcome the problems such as distortion and deformation caused by uneven stress due to the difference in wall thickness between the main wind blade 111 and the auxiliary wing structure 12 during the manufacturing process. In addition, it can also save material usage and reduce weight to reduce manufacturing costs.

In one embodiment, the auxiliary wing structure 12 and the main wind blade 111 are integrally formed.

By setting the auxiliary wing structure 12 and the main wind blade 111 as one piece, during processing, according to the optimized design of the cross-sectional shape and cross-sectional thickness of the auxiliary wing structure 12, the lateral distance, longitudinal distance and angle between the auxiliary wing structure 12 and the main wind blade 111, the composite wind guide blade structure is directly integrated and manufactured, which has the advantages of easy manufacturing, low cost, beautiful appearance and easy realization.

For example, the connection relationship between the auxiliary wing structure 12 and the main wind blade 111 is a non-fixed connection. In one embodiment of the present invention, the auxiliary wing structure 12 is independently driven by a driving structure and can rotate relative to the main wind blade 111 to adjust the air outlet direction guided by the auxiliary wing structure 12.

The auxiliary wing structure 12 may also be rotatable relative to the main wind blade 111. In some embodiments, the auxiliary wing structure 12 is independently driven by a driving structure and can rotate relative to the main wind blade 111 to adjust the wind direction guided by the auxiliary wing structure 12. The present disclosure does not limit the specific location of the driving structure, and any form that can drive the auxiliary wing structure 12 to rotate relative to the main wind blade 111 is within the protection scope.

For example, in one example, the left and right sides of the auxiliary wing structure 12 are connected to the two sides of the main wind blade 111 through a rotating shaft. The left and right sides of the auxiliary wing structure 12 can realize the rotation of the auxiliary wing by providing torque through a power source such as an independent drive motor or a steering gear set in a connecting bridge, wherein the connecting bridge is located at the air outlet of the panel enclosure, used to position the main wind blade 111, and the connecting bridge is a structure that connects the main wind blade structure 11 and the air conditioner inner casing. The connecting bridge is located inside the inner casing, and one end of the connecting bridge is set at the air outlet on the panel enclosure of the air conditioner inner casing (specifically, the inner side of the panel enclosure), and the other end is connected to the main wind blade 111; the number of connecting bridges can be multiple, for example, at least two connecting bridges are set at two spaced-apart locations of the panel enclosure of the air conditioner inner casing, which play the role of positioning the main wind blade and connecting the main wind blade and the inner casing. A driving motor can be set on the inner side of a connecting bridge to drive the main wind blade structure, and an independent driving motor can be set on the inner side of another connecting bridge to drive the auxiliary wing to rotate, so as to adjust the air outlet direction guided by the auxiliary wing structure. In addition, from the perspective of avoiding the influence on the air outlet, the driving structure can also be disposed on the support frame 112 .

In addition, in addition to being integrally formed with the main wind blade 111 or the auxiliary wing structure 12 being independently driven, the auxiliary wing structure 12 can also be assembled with the main wind blade 111 by means of a hook, that is, the auxiliary wing structure 12 is assembled with the main wind blade structure 11 by means of a hook. This method is suitable for situations where the main wind blade 111 and the auxiliary wing structure 12 cannot be integrally formed. The assembly of the auxiliary wing structure 12 with the main wind blade 111 by means of a hook has the advantage of easy disassembly. In both the integral molding and hook assembly methods, the auxiliary wing structure 12 can move with the main wind blade 111, without the need to set up an extra drive structure, and the structure is simple and the cost is low.

In the composite wind guide blade structure 1, the auxiliary wing structure 12 is emphasized. It should be noted that the main wind blade structure 11 includes a main wind blade 111 and a support frame 112. The main wind blade 111 can be a wind guide blade in various forms, and the length, shape, material and structural form of the main wind blade structure are not limited.

Example

In a second exemplary embodiment of the present invention, an air-conditioning indoor unit is provided, comprising any one of the composite air guide blade structures 1 mentioned in the present invention.

The air conditioner indoor unit is provided with an auxiliary wing structure 12, and the auxiliary wing structure 12 guides part of the cold air blown out from the main air blade 111 to the condensation-prone area on the outer surface of the main air blade 111. Generally speaking, the cold air blown out is guided to the bottom of the main air blade 111, so that the temperature on the inside and outside of the main air blade 111 is kept consistent, and the hot air at the bottom of the outer side is prevented from reaching the dew point temperature for condensation. In principle, the occurrence of condensation water is eliminated, and a better anti-condensation effect is achieved. At the same time, by providing the auxiliary wing structure 12 on the main air blade 111, the wind field effect is also improved. The direction of the wind flowing out along the gap between the main air blade 111 and the auxiliary wing structure 12 of the composite air guide blade structure 1 is smoother, and the turbulence noise caused by the blowing is also reduced.

In summary, the present invention provides a composite air guide blade structure and an air-conditioning indoor unit. By setting an auxiliary wing structure 12, the auxiliary wing structure 12 guides part of the cold air blown out from the main air blade 111 to blow toward the condensation-prone area on the outer surface of the main air blade 111. Generally speaking, the cold air blown out of the part is guided to blow toward the bottom of the main air blade 111, so that the temperature on the inside and outside of the main air blade 111 remains consistent, and the hot air at the bottom of the outer side is prevented from reaching the dew point temperature for condensation formation. In principle, the occurrence of condensation water is eliminated, and a better anti-condensation effect is achieved. At the same time, by setting the auxiliary wing structure 12 on the main air blade 111, the wind field effect is also improved. The direction of the wind flowing out along the gap between the main air blade 111 and the auxiliary wing structure 12 of the composite air guide blade structure 1 is smoother, and the turbulence noise caused by the blowing is also reduced. In addition, by changing at least one of the four factors, namely, the angle α between the auxiliary wing structure 12 and the dominant wind blade 111, the distance between the auxiliary wing structure 12 and the dominant wind blade 111 (including the lateral distance s and the longitudinal distance h), the cross-sectional shape of the auxiliary wing structure 12, and the cross-sectional thickness of the auxiliary wing structure 12, the wind field can be regulated, thereby achieving the anti-condensation effect, blowing comfort and turbulence noise regulation.

Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
