Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0049] Figure 1 is a schematic structural diagram of an air supply device according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 6 , an embodiment of the utility model provides an air supply device, including a body and a diverter component 180. The body defines a main air duct and an air outlet connected to the main air duct, and the main air duct includes an air outlet section 160 connected to the air outlet. The air duct walls on both sides of the main air duct are respectively a first air duct wall 192 and a second air duct wall 191. The diverter component 180 is arranged in the air outlet section 160, and extends in the air outlet direction of the main air duct, and is spaced apart from the first air duct wall 192 and the second air duct wall 191, so as to at least separate the air outlet section 160 into a first sub-air duct 162 and a second sub-air duct 161 spaced apart from each other. Among them, the width of the diverter component 180 gradually increases along the air outlet direction. Each corner on both sides of the air outlet end of the diverter component 180 is formed with a first groove 187 extending along the length direction of the corner.

[0050] In the air supply device of the embodiment of the utility model, when the air supply device is turned on, the wind goes along the outlet section 160 of the main air duct to the diverter component 180, and then enters the first sub-air duct 162 and the second sub-air duct 161 respectively, and then blows out in two different directions from the first sub-air duct 162 and the second sub-air duct 161 respectively. In addition, since the width of the diverter component 180 gradually increases along the air outlet direction, each corner of the air outlet section 160 of the diverter component 180 on both sides is formed with a first groove 187 extending along the length direction of the corner. When the air delivered by the air supply device is cold air, the setting of the first groove 187 can keep the cold air away from the front end surface of the diverter component 180, that is, the cold air and the air with a higher temperature outside the air supply device will not gather at the air outlet, thereby avoiding the generation of condensation.

[0051] Furthermore, the width of the diversion component 180 gradually increases along the air outlet direction, which also increases the angle between the air outlet direction of the first sub-air duct 162 and the air outlet direction of the second sub-air duct 161, so that the blown wind will not converge at the air outlet, and the wind can be better blown out from two different directions.

[0052] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the first sub-air duct 162 and the second sub-air duct 161 lead to different sub-air outlets. The air outlet end of the diverter component 180 defines two sub-air outlets in the air outlet.

[0053] In this embodiment, the air outlet connected to the first sub-air duct 162 is the first sub-air outlet, and the air outlet connected to the second sub-air duct 161 is the second sub-air outlet. The wind entering the first sub-air duct 162 is blown out by the first sub-air outlet, and the wind entering the second sub-air duct 161 is blown out by the second sub-air outlet, so that the wind can be better blown out in two different directions.

[0054] In some embodiments of the present invention, Figures 2 to 4 As shown, a second groove 165 extending along the length direction of each edge on both sides of the air outlet is formed.

[0055] As can be seen from the above embodiment, each corner of both sides of the air outlet section 160 of the diverter component 180 is provided with a first groove 187. In this embodiment, the second groove 165 is provided so that both sides of each sub-air outlet are provided with grooves, that is, when the air delivered by the air supply device is cold air, the first groove 187 can keep the cold air away from the front end surface of the diverter component 180, and the second groove 165 can keep the cold air away from the casing on both sides of the air outlet, so as to better avoid the generation of condensation.

[0056] In some embodiments of the present invention, Figures 2 to 4 As shown, the two first grooves 187 are arranged so as to reduce the width of the air outlet end along the air outlet direction.

[0057] In some alternative embodiments, the two first grooves 187 are arranged so that the width of the air outlet end first decreases and then remains unchanged.

[0058] Alternatively, the two first grooves 187 are arranged so that the width of the air outlet end first decreases and then increases, and the magnitude of the decrease is greater than the magnitude of the increase.

[0059] In some embodiments of the present invention, Figures 2 to 4 As shown, the two second grooves 165 are arranged so that the width of the air outlet increases along the air outlet direction, or increases first and then remains unchanged, or increases first and then decreases and the increase amplitude is greater than the decrease amplitude. The amplitude here refers to the change in the size in the width direction of the air outlet end.

[0060] In some embodiments of the present invention, Figures 2 to 4 As shown, the width of the second groove 165 along the width direction of the air outlet end is greater than the width of the first groove 187 along the width direction of the air outlet end.

[0061] As can be seen from the above embodiment, the diverter component 180 blows the wind in two different directions. At this time, the wind sent out by the first sub-duct 162 is concentrated on the first duct wall 192, that is, the side of the second groove 165 close to the first sub-duct 162, and the wind sent out by the second sub-duct 161 is concentrated on the second duct wall 191, that is, the side of the second groove 165 close to the second sub-duct 161. In this embodiment, the width of the groove on the side with a larger air output is larger along the width direction of the air outlet end, which can better prevent the generation of condensation.

[0062] Preferably, the width of the first groove 187 along the width direction of the air outlet is not less than 3 mm. The width of the second groove 165 along the width direction of the air outlet is not less than 13 mm.

[0063] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, along the air outlet direction, the width of the first sub-duct 162 gradually increases, and the width of the second sub-duct 161 gradually increases, gradually decreases, or remains unchanged. And the width ratio between the end and the beginning of the first sub-duct 162 is greater than the width ratio between the end and the beginning of the second sub-duct 161.

[0064] In this embodiment, since the width of the first sub-air duct 162 gradually increases from its beginning to the end, a diffusion section is formed, and the speed of the wind passing through the first sub-air duct 162 increases. And the width ratio between the end and the beginning of the second sub-air duct 161 is smaller than the width ratio between the end and the beginning of the first sub-air duct 162, that is, the speed of the wind blown out from the first sub-air duct 162 is always faster than the speed of the wind blown out from the second sub-air duct 161, and the air supply distance of the first sub-air duct 162 is farther. The air supply device supplies air at two different wind speeds, which satisfies the simultaneous air supply of long distance and short distance, improves the air supply efficiency, and enhances the user experience.

[0065] In this embodiment, the width of the second sub-air duct 161 gradually increases, decreases or remains unchanged from its starting end to the end, so that the second sub-air duct 161 forms a pressure diffusion section or an isobaric section, or a precise air supply section to a certain area.

[0066] Preferably, the width of the second sub-air duct 161 remains unchanged from its beginning to its end to form an isobaric section, and the wind speed passing through the second sub-air duct 161 does not change.

[0067] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4As shown, the first air duct wall 192 includes a first section 164 for defining the air outlet section 160, and the second air duct wall 191 includes a second section 163 for defining the air outlet section 160. The first section 164 and the second section 163 are at an angle, and along the air outlet direction of the air outlet section 160, the rearward extension surfaces of the first section 164 and the second section 163 intersect.

[0068] In this embodiment, there is an angle between the first section 164 and the second section 163, that is, the distance between the first section 164 and the second section 163 gradually increases along the wind outlet direction, forming a diffuser section, so that the speed of the wind passing through the first section 164 and the second section 163 increases.

[0069] In this embodiment, the angle between the first section 164 and the second section 163 is 59° to 64°. For example, the angle between the first section 164 and the second section 163 is 59°, 60°, 61°, 62°, 63°, 64°. This increases the flow range of the wind passing through the first section 164 and the second section 163 in the main air duct, further increases the wind outlet angle, increases the wind outlet range, and ultimately improves the air supply efficiency of the air supply device.

[0070] In some embodiments of the present invention, Figures 1 to 4 As shown, the side wall surface of the diverter component 180 facing the first air duct wall 192 is a side wall surface arched toward the first air duct wall 192, recorded as the first guide surface 182, and the other opposite side wall surface is a side wall surface arched toward the first air duct wall 192, recorded as the second guide surface 181, the first guide surface 182 and / or the second guide surface 181 are arc-shaped, or the first guide surface 182 and / or the second guide surface 181 include a plurality of arc-shaped surfaces connected in sequence along the air outlet direction.

[0071] It can be seen from the above embodiment that the distance between the first section 164 of the first air duct wall 192 and the second section 163 of the second air duct wall 191 gradually increases along the air outlet direction. In this embodiment, the first guide surface 182 is an arch of the first air duct wall 192, so the distance between the first guide surface 182 and the first air duct wall 192 also gradually increases along the air outlet direction, that is, the sub-air duct formed between the first guide surface 182 and the first air duct wall 192 is a pressure expansion section, which increases the flow rate of the wind.

[0072] Preferably, the first guide surface 182 of the diverter component 180 and the second guide surface 181 arranged opposite to the first channel are both arc surfaces, so that the wind resistance is reduced during the flow process.

[0073] Of course, one of the first guide surface 182 and the second guide surface 181 may be an arc surface.

[0074] In some embodiments of the present invention, Figure 3 As shown, the first guide surface 182 includes two arc-shaped surfaces, namely a first arc-shaped surface and a second arc-shaped surface. The first arc-shaped surface is located on the upstream side of the second arc-shaped surface, and the radius of the circle 186 where the first arc-shaped surface is located is smaller than the radius of the circle 184 where the second arc-shaped surface is located, and the radius of the circle 186 where the first arc-shaped surface is located is equal to 0.36 to 0.41 times the radius of the circle 184 where the second arc-shaped surface is located.

[0075] In this embodiment, the first arc-shaped surface and the second arc-shaped surface are tangent and connected to form the first guide surface 182, and the radius of the circle 186 where the first arc-shaped surface is located is smaller than the radius of the circle 184 where the second arc-shaped surface is located. Preferably, the radius of the circle 186 where the first arc-shaped surface is located is equal to 0.36 to 0.41 times the radius of the circle 184 where the second arc-shaped surface is located, for example, the radius of the circle 186 where the first arc-shaped surface is located is equal to 0.36, 0.37, 0.38, 0.39, 0.40, 0.41 times the radius of the circle 184184 where the second arc-shaped surface is located.

[0076] In some embodiments of the present invention, Figure 3 As shown, the second guide surface 181 includes two arc-shaped surfaces, namely a third arc-shaped surface and a fourth arc-shaped surface. The third arc-shaped surface is located on the upstream side of the fourth arc-shaped surface, and the radius of the circle 185 where the third arc-shaped surface is located is smaller than the radius of the circle 183 where the fourth arc-shaped surface is located, and the radius of the circle 185 where the third arc-shaped surface is located is equal to 0.36 to 0.43 times the radius of the circle 183 where the fourth arc-shaped surface is located.

[0077] In this embodiment, the third arc-shaped surface and the fourth arc-shaped surface are tangent and connected to form the second guide surface 181, and the radius of the circle 185 where the third arc-shaped surface is located is smaller than the radius of the circle 183 where the fourth arc-shaped surface is located. Preferably, the radius of the circle 185 where the third arc-shaped surface is located is equal to 0.36, 0.37, 0.38, 0.39, 0.40, 0.41, 0.42, 0.43 times the radius of the circle 183 where the fourth arc-shaped surface is located.

[0078] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the width ratio between the end and the beginning of the first sub-air duct 162 is greater than 1.3.

[0079] In this embodiment, the width of the beginning of the first sub-duct 162 and the width of the end of the second sub-duct 161 are greater than 1.3, and the width of the first sub-duct 162 gradually increases along the air outlet direction, so that the wind speed passing through the first sub-duct 162 increases, meeting the long-distance air supply requirements. Preferably, the ratio of the width of the beginning of the first sub-duct 162 to the width of the end of the second sub-duct 161 is 1.5.

[0080] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the width ratio between the end and the beginning of the second sub-air duct 161 is 0.8 to 1.2.

[0081] In this embodiment, the width ratio between the end and the beginning of the second sub-air duct 161 is 0.8, 0.9, 1.0, 1.1 or 1.2, so that the wind speed sent from the second sub-air duct 161 is always less than the wind speed sent from the first sub-air duct 162, so that the second sub-air duct 161 can deliver air at a short distance. Preferably, the width ratio between the end and the beginning of the second sub-air duct 161 is 1.0.

[0082] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the main air duct also has a first section 120 and a second section 150 connected in sequence in the air outlet direction, and the end of the second section 150 is connected to the air outlet section 160. The extension direction of the first section 120 and the extension direction of the air outlet section 160 form an angle.

[0083] In this embodiment, since the extension direction of the first section 120 of the main air duct and the extension direction of the air outlet section 160 form an angle, the wind changes its forward direction in the process of blowing from the first section 120 to the air outlet section 160. The wind flowing in the first section 120 is not uniform, and when the wind blows toward the corner of the first section 120 and the air outlet section 160, it collides with the air duct wall, so that the wind blown out by the air supply device can be more uniform, further improving the user experience.

[0084] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the central axis of the first section 120 and the central axis of the air outlet section 160 are both straight lines, and the central axis of the second section 150 is an arc line that smoothly transitions between the central axis of the first section 120 and the central axis of the air outlet section 160 .

[0085] It can be seen from the above embodiments that there is an angle between the extension direction of the first section 120 of the main air duct and the extension direction of the air outlet section 160. In this embodiment, the first section 120 and the air outlet section 160 are both straight sections. The wind enters the first section 120 of the main air duct, moves in a straight line in the first section 120, and then enters the second section 150 of the main air duct, and then the movement direction begins to smoothly transition to the air outlet section 160 in an arc shape to the air outlet section 160. The setting of the second section 150 makes the wind move more smoothly, avoiding the problem of confusion in the movement direction of the wind due to the sudden turning of the main air duct.

[0086] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the air inlet end of the diverter component 180 is a pointed end, and the pointed end of the diverter component 180 extends into the second section 150 or is adjacent to the second section 150 .

[0087] As can be seen from the above embodiment, the second section 150 is located between the first section 120 and the air outlet section 160, and connects the first section 120 with the air outlet section 160. In this embodiment, the tip of the diverter component 180 is located in the second section 150. When the air supply device is turned on, the diverter component 180 will not be unevenly distributed because the tip of the diverter component 180 is too far away from the entrance of the first section 120, and the noise will not be too loud because the tip of the diverter component 180 is too close to the entrance of the first section 120.

[0088] In some embodiments of the present invention, Figures 2 to 4 As shown, the first duct wall 192 further includes a third section 122 for defining the first section 120, and the second duct wall 191 further includes a fourth section 121 for defining the first section 120. The extension surface of the fourth section 121 intersects with the third section 122 or with the extension surface of the third section 122.

[0089] In this embodiment, the distance between the third section 122 and the fourth section 121 gradually increases or decreases along the wind outlet direction. When the distance gradually decreases along the wind outlet direction, the wind in the first section 120 can be more concentrated and better diverted at the diverter component 180. When the distance gradually increases along the wind outlet direction, the wind speed in the first section 120 can be faster.

[0090] In this embodiment, the angle between the third section 122 and the fourth section 121 is 18° to 22°. For example, the angle between the third section 122 and the fourth section 121 is 18°, 19°, 20°, 21°, 22°. This allows better wind gathering and transportation.

[0091] In some embodiments of the present invention, Figure 4As shown, in a first plane containing the tip of the diverter component 180 and parallel to the air outlet, the distance from the first air duct wall 192 to the tip of the diverter component 180 is recorded as a first distance 142, the distance between the first air duct wall 192 and the second air duct wall 191 is recorded as a second distance 141, and the distance from the second air duct wall 191 to the tip of the diverter component 180 is recorded as a third distance 143, and the first distance 142 is equal to 0.41 to 0.50 times the second distance 141.

[0092] It can be seen from the above embodiments that there is an angle between the first section 120 and the air outlet section 160, and the wind has inertia during the movement process, so most of the wind reaching the air outlet section 160 will be concentrated on the side close to the first air duct wall 192. A first sub-air duct 162 is formed between the first air duct wall 192 and the diverter component 180, and a second sub-air duct 161 is formed between the second air duct wall 191 and the diverter component 180. Then in this embodiment, the first distance 142 is equal to 0.41 to 0.50 times the second distance 141, that is, the inlet of the first sub-air duct 162 is smaller than the inlet of the second sub-air duct 161, which further plays a role in uniform air outlet. For example, the first distance 142 is equal to 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48, 0.49, 0.50 times the second distance 141.

[0093] In some embodiments of the present invention, Figure 4 As shown, the ratio of the sum of the first distance 142 and the third distance 143 to the second distance 141 is greater than 0.9.

[0094] In this embodiment, the distance from the tip position to the first air duct wall 192 and the distance from the tip position to the second air duct wall 191 are added together, and the total distance is more than 0.9 times the distance between the first air duct wall 192 and the second air duct wall 191. That is to say, the shape of the tip of the diversion component 180 is very sharp, which can better divert the wind.

[0095] Preferably, the ratio of the sum of the first distance 142 and the third distance 143 to the second distance 141 is 0.99.

[0096] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, when the distance from the beginning of the third section 122 to the tip of the diverter component 180 is recorded as the fourth distance 132 and the distance from the beginning of the third section 122 to the air outlet is recorded as the fifth distance 131, the fourth distance 132 is equal to 0.41 to 0.56 times the fifth distance 131.

[0097] It can be seen from the above embodiments that the tip of the diverter component 180 is located in the second section 150 or in the air outlet section 160 adjacent to the second section 150. In this embodiment, when the air supply device is turned on, the wind enters the main air duct, and then moves the fourth distance 132 to reach the tip of the diverter component 180, starts to divert at the tip of the diverter component 180, and then moves in at least two directions to reach the air outlet. The fourth distance 132 is equal to 0.41 to 0.56 times the fifth distance 131, that is, for example, 0.41, 0.42, 0.43, 0.44, 0.45, 0.46, 0.47, 0.48, 0.49, 0.50, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56 times. Preferably, the third distance 143 is equal to 0.49 to 0.51 times the fourth distance 132. In this way, the diverter component 180 will not be too close to the upstream end of the first section 120, thereby avoiding an increase in noise and a decrease in air volume. At the same time, the diverter component 180 will not be too far away from the upstream end of the first section 120, thereby not affecting the diverting effect of the wind.

[0098] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the third section 122 and the fourth section 121 are at an angle, and along the air outlet direction of the first section 120, the rearward extension surfaces of the third section 122 and the fourth section 121 intersect. The first air duct wall 192 further includes a fifth section 152 for defining the second section 150, and the second air duct wall 191 further includes a sixth section 151 for defining the second section 150. The fifth section 152 and / or the sixth section 151 are in an arc shape to smoothly connect between the corresponding air duct wall of the first section 120 and the air duct wall of the air outlet section 160.

[0099] It can be seen from the above embodiment that the second section 150 of the main air duct smoothly connects the first section 120 of the main air duct to the outlet section 160, and the extension direction of the first section 120 and the extension direction of the outlet section 160 form an angle, and due to inertia, most of the wind will be concentrated on the side of the outlet section 160 close to the first air duct wall 192. In this embodiment, when the wind turns in the second section 150, since the fillet radius of the fifth section 152 is smaller than the fillet radius of the sixth section 151, the wind also flows more toward the side of the second air duct wall 191, which plays a role in uniform wind outlet.

[0100] Preferably, the fillet radius of the fifth segment 152 is 0.82 to 0.86 times the fillet radius of the sixth segment 151. For example, the fillet radius of the fifth segment 152 is 0.82, 0.83, 0.84, 0.85, or 0.86 times the fillet radius of the sixth segment 151.

[0101] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, a crossflow impeller 110 is rotatably disposed in the main air duct, and the first section 120 and the second section 150 are located between the crossflow impeller 110 and the air outlet. The beginning of the third section 122 is a volute tongue 170 that cooperates with the crossflow impeller 110.

[0102] In this embodiment, when the air supply device is turned on, the crossflow impeller 110 is started, and the wind generated by the crossflow impeller 110 enters the first section 120 of the main air duct, then enters the second section 150, and finally passes through the air outlet section 160 and is blown out from the air outlet.

[0103] Figure 5 2 is a schematic structural diagram of an air conditioner according to an embodiment of the utility model. The utility model embodiment also provides an air conditioner, including an air supply device and a heat exchanger 200 as in any of the above embodiments. The heat exchanger 200 is arranged in the main air duct of the body of the air supply device.

[0104] In this embodiment, the air supply device can not only prevent the generation of condensation at the air outlet of the air conditioner, but also prevent direct blowing of the air conditioner, thereby improving the user experience.

[0105] Figure 6 This is a main flow diagram of the air flow of the air conditioner passing through the diversion component according to an embodiment of the utility model. Figure 6 The first color area 301 represents the first airflow direction, and the second color area 302 represents the second airflow direction. Figure 6 It can be seen that the wind passing through the first sub-air duct 162 is mainly blown out along the first airflow direction. The wind passing through the second sub-air duct 161 is mainly blown out along the second airflow direction. In addition, the airflow is away from the front end of the diverter component 180 and both sides of the air outlet.
