Hereinafter, an air conditioner 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1, an air conditioner 100 according to an embodiment of the present invention includes: the air conditioner comprises an air conditioner body 10, a cross flow wind wheel 20 and an air guide part 30. The air conditioner body 10 has a through-flow air duct 101 and an air outlet 102 communicated with the through-flow air duct 101, and the through-flow wind wheel 20 is disposed in the through-flow air duct 101 and located upstream of the air outlet 102. Therefore, when the cross flow wind wheel 20 rotates, the airflow can enter the cross flow air duct 101 and then be sent out of the air conditioner body 10 from the air outlet 102.

It should be noted that the specific configuration of the air conditioner body 10 according to the embodiment of the present invention is not limited, and may be determined according to the specific type of the air conditioner 100, and is not limited herein. In addition, in some embodiments of the present invention, the air conditioner body 10 may further include an air inlet 103 communicated with the cross-flow air duct 101, and the cross-flow wind wheel 20 is disposed in the cross-flow air duct 101 and located downstream of the air inlet 103, so that when the cross-flow wind wheel 20 rotates, air outside the air conditioner body 10 may enter the air conditioner body 10 from the air inlet 103, then enter the cross-flow air duct 101, and then be sent out of the air conditioner body 10 from the air outlet 102.

As shown in fig. 1, in a cross section perpendicular to a rotation axis 201 of cross-flow wind wheel 20, that is, perpendicular to rotation axis 201 of cross-flow wind wheel 20, for example, in the cross section shown in fig. 1, air conditioner body 10 includes first scroll casing 11 and second scroll casing 12 disposed opposite to each other, and cross-flow duct 101 is located between first scroll casing 11 and second scroll casing 12. It should be noted that the first volute 11 may be an integral piece, or may be formed by splicing a plurality of parts, and the second volute 12 may be an integral piece, or may be formed by splicing a plurality of parts, and needs to be determined according to a specific type of the air conditioner body 10, which is not limited herein.

As shown in fig. 1, the wind guiding member 30 comprises a wind deflector 31 rotatable about a pivot axis 301 at the wind outlet 102, e.g. dashed lines in fig. 1 indicate some rotatable positions of the wind deflector 31. When the air output of the air conditioner 100 is the maximum, as shown in fig. 5 and 6, a set air duct 1013 is defined between the air guide 31 and the first scroll casing 11, and the width of the set air duct 1013 in the cross section increases first and then decreases along the air output direction. That is, when the air output of the air conditioner 100 is the maximum, the cross-sectional width of the air channel 1013 is configured to expand first and then contract second along the air output direction.

It should be noted that the air output of the air conditioner 100 can be actually measured or obtained by numerical simulation, and it is understood that the air output may vary according to the specific type of the air conditioner 100. In addition, the width of the air duct 1013 in the cross section refers to a width perpendicular to the airflow direction at the inlet of the air duct 1013, such as L2, L3 \823030l \\8230lnshown in the figure.

Based on the bernoulli equation, static pressure + dynamic pressure = constant, when the air current in the through-flow air duct 101 reaches the set air duct 1013, the two stages can be successively divided into a first stage, the section width of the set air duct 1013 is gradually increased, the air current is gradually decreased due to the unchanged flow rate, but the flow channel width is increased, so that the air current speed is decreased, the air current dynamic pressure is decreased, and the static pressure is increased.

In the related art, for example, a mobile air conditioner, a window air conditioner, or an air conditioner on-hook, etc., a cross-flow air duct component is adopted, a cross-flow wind wheel rotates for one-time pressurization, air is discharged through the cross-flow air duct, and the air is guided by an air guide plate at an air outlet to meet the requirement of an air supply angle.

According to the air conditioner 100 of the embodiment of the present invention, when the air output of the air conditioner 100 is the largest, the cross-sectional width of the set air duct 1013 between the air guiding surface 311 and the first volute 11 is first increased and then decreased along the air output direction, so that primary pressurization can be realized by the rotation of the cross flow wind wheel 20 to form a stable airflow field, and when the airflow flows to the set air duct 1013, the static pressure and the dynamic pressure of the air output can be increased, thereby realizing secondary pressurization, improving the anti-resistance capability of the air output, meeting the requirements of large air volume, large-range and long-distance air supply, and solving the problems of air volume attenuation, small air supply range and short air supply distance.

In some embodiments, as shown in fig. 1, the first volute 11 includes a first straight line segment 111, a volute tongue segment 112 connected to an inner end of the first straight line segment 111, and a first flared segment 113 connected to an outer end of the first straight line segment 111, and the second volute 12 includes a second straight line segment 121, and a second flared segment 122 connected to an outer end of the second straight line segment 121, with reference to fig. 2, the first flared segment 113 extends from inside to outside first in a direction away from an extension line S1 of the first straight line segment and then in a direction close to the extension line S1 of the first straight line segment, and the second flared segment 122 extends from inside to outside in a direction away from the extension line S2 of the second straight line segment. It should be noted that "inside" in this paragraph refers to a direction in the airflow direction near the inlet of the cross-flow duct 101, and "outside" refers to a direction in the airflow direction near the outlet of the cross-flow duct 101.

Therefore, by setting the shapes of the first volute 11 and the second volute 12 as described above and referring to fig. 2, most or all of the first flared section 113 and the second flared section 122 may be located on two sides of the extension line S1 of the first straight line segment and the extension line S2 of the second straight line segment, respectively, so that the outer end of the cross-flow duct 101 is in a flared shape, and the air outlet area of the cross-flow duct 101 is increased at this position, thereby increasing the air outlet volume. In short, by designing the first flared section 113 and the second flared section 122, the outer end of the cross-flow air duct 101 is in a flared shape, so as to increase the air outlet area of the cross-flow air duct 101 at that position, thereby increasing the air outlet volume.

Referring to fig. 6, when the first and second spiral cases 11 and 12 are configured as described above, setting the width of the air duct 1013 in the cross section may mean that, in the cross section, a vertical line segment is drawn from an outer end point D of the second straight line segment 121 to the first straight line segment 111 to obtain a vertical foot a, the length of the vertical foot AD is L1, and based on the vertical line segment, a plurality of straight lines parallel to the vertical line segment are drawn, and each straight line has a length between the first spiral case 11 and the air guide surface 311 of the air guide 31, as shown in fig. 6 as L2 and L3 \8230, li \8230, and Ln is the width of each position of the air duct 1013.

Further, in some embodiments of the present invention, when the air output of the air conditioner 100 is the maximum, the cross-sectional width between the extension line S3 of the air guiding surface and the first scroll casing 11, such as Ln +1 and Ln +2 shown in fig. 6, is continuously gradually decreased along the air output direction relative to the outlet cross-sectional width Ln of the setting air duct 1013. From this, can realize the secondary pressure boost of air-out air current better, promote the total pressure of air-out, promote the anti ability of hindering of air-out promptly for the air supply distance is far away.

As shown in FIG. 7, in a cross section perpendicular to the rotation axis 201 of the cross-flow wind wheel 20, the outer end point of the first volute 11 (the outer end point of the first diverging section 113 shown in FIG. 7) is M, the outer end point of the second volute 12 (the outer end point of the second diverging section 122 shown in FIG. 7) is N, with O as a center of circle and R as a radius as a base circle, the projection point of the pivot axis 301 is Oo located within the base circle, a foothold point K is obtained by making a perpendicular line to the segment MN through the point O, both end points of the wind guide 31 in the rotation circumferential direction are P and Q, respectively, and in combination with FIG. 8, a perpendicular bisector L is made to the segment PQ and a perpendicular line to the segment L through the point Oo is made to the segment MN to obtain a foothold point B, wherein MK is 0.4. Ltoreq. MN.0.6MN, MK. Ltoreq. KO.ltoreq. KO.0.85MK, MK. Ltoreq. R.ltoreq. R.ltoreq.0.75KO.0.9KO.ltoreq.0.5R.

From this, this application sets for above-mentioned parameter through ingenious, sets for the position of pivot axis 301 of air guide 31 as above, matches the circumference width of design air guide 31 simultaneously to can guarantee effectively when the air output of air conditioner 100 is the biggest, set for the width of wind channel 1013 on the cross section and increase earlier the back and reduce along the air-out direction, thereby compromise big amount of wind, low noise, big air supply scope, satisfy the requirement of heating, refrigeration travelling comfort.

For example, as shown in fig. 1, when the air conditioner 100 is a mobile air conditioner, the first flared section 113 is located at the rear side of the second flared section 122, the upper end of the first flared section 113 is the outer end of the first scroll 11, the upper end of the second flared section 122 is the outer end of the second scroll 12, and the upper end of the first flared section 113 is higher than the upper end of the second flared section 122. Therefore, when the air guide 31 rotates to a position close to the second flared section 122 on the front side, the rear surface of the air guide 31 is the air guide surface 311 to define a first air outlet channel 1011 located on the rear side of the air guide 31 with the first volute 11, so as to realize backward air supply (refer to fig. 3), and when the air guide 31 rotates to a position close to the first flared section 113 on the rear side, the front surface of the air guide 31 is the air guide surface 311 to define a second air outlet channel 1012 located on the front side of the air guide 31 with the second volute 12, so as to realize forward air supply (refer to fig. 4).

At this time, by setting the above parameters, (1) the strong air flow of the mobile air conditioner of the present invention can be increased to 600, and compared with the conventional mobile air conditioner with the maximum air flow of 450, the air flow is increased by 33.3%; (2) The air supply distance of the mobile air conditioner can reach 11.0m, and ultra-far air supply is realized, while the air supply distance of the traditional mobile air conditioner under the same test strip is only 5.0m; (3) The swing range of the mobile air conditioner can reach 180 degrees, the whole house can supply air without dead angles, and the conventional mobile air conditioner can only sweep air within 30 degrees right in front of a product. It should be noted that other configurations of the mobile air conditioner according to the embodiment of the present invention, such as a heat exchanger, a base pan, a face frame, a panel, etc., and operations thereof are known to those skilled in the art and will not be described in detail herein.

For example, as shown in fig. 9, the air conditioner 100 is an indoor unit, the first flared section 113 is located on the upper side of the second flared section 122, the front end of the first flared section 113 is the outer end of the first scroll casing 11, the front end of the second flared section 122 is the outer end of the second scroll casing 12, and the front end of the first flared section 113 is located on the front side of the front end of the second flared section 122. Therefore, when the air guide 31 rotates to a position close to the second flared section 122 below, the upper surface of the air guide 31 is the air guide surface 311 to define a first air outlet channel 1011 located above the air guide 31 with the first volute 11 so as to supply air upwards (as shown in fig. 9), and when the air guide 31 rotates to a position close to the first flared section 113 above, the lower surface of the air guide 31 is the air guide surface 311 to define a second air outlet channel 1012 located below the air guide 31 with the second volute 12 so as to supply air downwards (as shown in fig. 10).

At this time, by setting the above parameters, (1) the strong air flow of the indoor hanging machine of the invention can be increased to 750 sides, and compared with the conventional indoor hanging machine with the maximum air flow of 680 sides, the air flow is increased by 10.3%; (2) The air supply distance of the indoor hanging machine can reach 9.0m, ultra-long air supply is realized, and the air supply distance of the conventional indoor hanging machine under the same test strip is only 7.5m; (3) The air swinging range of the indoor hanging machine can reach 180 degrees, the whole-house dead-angle-free air supply is really realized, and the conventional indoor hanging machine can only sweep air within the range of 75 degrees. It should be noted that other configurations of indoor hangs, such as heat exchangers, chassis, face frames, panels, etc. and operations according to embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.

In some embodiments, as shown in fig. 1, the wind guide member 31 includes a wind guide surface 311 and an outer facing 312, the wind guide member 31 has a first wind guide state and a second wind guide state, as shown in fig. 3, in the first wind guide state, the wind guide surface 311 is located on a side of the outer facing 312 close to the first scroll 11, and a first wind outlet duct 1011 is defined between the wind guide surface 311 and the first scroll 11, and as shown in fig. 4, in the second wind guide state, the wind guide surface 311 is located on a side of the outer facing 312 close to the second scroll 12, and a second wind outlet duct 1012 is defined between the wind guide surface 311 and the second scroll 12.

It can be understood that, in the process of the rotation of the air guide 31 around the pivot axis 301, the position where the air guide 31 maximally shields the air outlet 102 is defined as an initial position, and when the air guide 31 is located at a side of the initial position, which is close to the second volute 12 and is far away from the first volute 11, and the air guide 31 rotates in a rotation angle range (referred to as a first angle range), a first air outlet duct 1011 can be defined between the air guide surface 311 and the first volute 11, at this time, the air guide 31 is in the first air guiding state, that is, the air guide 31 in the first air guiding state does not correspond to an angle, but corresponds to multiple angles.

Similarly, in the process that the air guide 31 rotates around the pivot axis 301, when the air guide 31 is located at the side of the initial position close to the first spiral case 11 and far away from the second spiral case 12, and the air guide 31 rotates within a rotation angle range (referred to as a second angle range for short), a second air outlet channel 1012 can be defined between the air guide surface 311 and the second spiral case 12, and at this time, the air guide 31 is located in a second air guiding state, that is, the air guide 31 in the second air guiding state does not correspond to one angle but corresponds to multiple angles. In addition, it should be noted that, according to different specific types of the air conditioner 100, specific values of the first angle range and the second angle range may be set according to practical situations, and are not limited herein.

Therefore, it can be understood that when the air output of the air conditioner 100 is the maximum, the air path 1013 is defined between the air guide 31 and the first spiral case 11, and therefore, the air path 1013 is set as a specific first air-out path 1011, that is, when the air guide 31 is in the first air guiding state and rotates to the set angle position, the first air-out path 1011 defined between the air guide 31 and the first spiral case 11 is set as the air path 1013. Note that, when the air volume is the maximum, the specific set angular position to which the air guide 31 is rotated may be different, and therefore, the set angular position is not limited.

In some embodiments, as shown in fig. 1, in a circumferential direction of rotation of the wind guide 31 (which may be a direction toward the first scroll casing 11 and away from the second scroll casing 12, such as a counterclockwise direction in fig. 1, or a direction toward the second scroll casing 12 and away from the first scroll casing 11, such as a clockwise direction in fig. 1), a distance between the wind guide surface 311 and the outer facing 312 increases first and then decreases. Accordingly, a certain distance can be formed between the air guide surface 311 and the exterior surface 312 on the premise that the structural shape of the set air duct 1013 meets the above requirements, thereby improving the problem of dew formation on the air guide 31.

In some embodiments, as shown in fig. 5 and 6, both side wall surfaces of the air duct 1013 in the width direction are smooth curved surfaces, for example, in the specific example shown in fig. 5 and 6, a side surface of the first flared portion 113 facing the second flared portion 122 and the air guide surface 311 are smooth curved surfaces. Therefore, when the air output of the air conditioner 100 is the largest, the surfaces on both sides of the width of the set air duct 1013 are respectively streamline curved surfaces, and the cross section of the set air duct 1013 may be approximately spherical, so that the set air duct 1013 may realize smooth transition from gradual increase to gradual decrease of the cross section width, thereby better realizing secondary supercharging. Of course, the present invention is not limited to this, and in other embodiments of the present invention, a side surface of the first flared section 113 facing the second flared section 122 and the wind guiding surface 311 may also be configured as a non-smooth curved surface, for example, a curved surface of a broken line, and the like, which are not described herein again.

In the specific example shown in fig. 11, the wind guiding surface 311 may be a cambered surface and have a curvature ρ 1, and the exterior surface 312 may include a cambered surface section 3121, and the curvature of the cambered surface section 3121 is ρ 2, where 0 < ρ 1 < ρ 2 ≦ 0.03. From this, air guide surface 311 and exterior 312 of air guide 31 all accord with the coanda effect for the air current is the malleation partially with higher speed, makes the air current wrap up air guide 31 completely, avoids the air current to break away from air guide 31 surface formation swirl, avoids cold and hot intersection to form the drop of water promptly, solves the problem that forms the condensation on the air guide 31.

With reference to fig. 12, the exterior finishing surface 312 further includes two inclined surface sections 3122, the two inclined surface sections 3122 are respectively connected to two ends of the arc surface section 3121, that is, two ends of the arc surface section 3121 in the arc length direction are respectively connected to an inclined surface section 3122, an included angle α between the inclined surface section 3122 and a tangent line of the arc surface section 3121 (that is, a tangent line at the respective ends of the inclined surface section 3122 and the arc surface section 3121) is satisfied, and α is greater than or equal to 0 ° and less than or equal to 25 °. From this, through design non-curved section at the both ends of exterior finish 312 and with cambered surface section 3121 formation alpha contained angle to make exterior finish 312 accord with the coanda effect, make the air current positive pressure with higher speed locally, make the air current can wrap up air guide 31 perfectly, avoid the air current to break away from air guide 31 surface and form the swirl, avoid the cold and hot formation drop of water that intersects promptly, solve the problem that forms the condensation on the air guide 31.
