[0040] Figure 1 1 is a schematic structural diagram of a vertical air conditioner indoor unit 10 according to an embodiment of the present utility model. Figure 1 As shown, and refer to Figures 2 to 3 The embodiment of the utility model provides a vertical air conditioner indoor unit 10, including a body 100, a diverter component 400 and two drainage air ducts. The body 100 defines a vertical main air duct 110 and a vertical strip-shaped air outlet connected to its outlet, and a crossflow wind wheel 130 is rotatably arranged in the main air duct 110 so that an air outlet section of the main air duct is defined between the crossflow wind wheel 130 and the outlet of the main air duct. The vertically extending diverter component 400 is arranged in the first section 113 and extends in the air outlet direction to laterally divide the first section 113 into two mutually spaced sub-air ducts, and the two sub-air ducts lead to different sub-air outlets. Among them, the diverter component 400 and the body 100 define two sub-air outlets in the air outlet. The two drainage air ducts are respectively arranged on both sides of the air outlet. Each drainage air duct includes a drainage air outlet, which is arranged on a side of the corresponding sub-air outlet away from another sub-air outlet, so as to guide the airflow of the drainage air duct to be blown out from the drainage air outlet when the corresponding sub-air outlet blows out airflow.

[0041] In this embodiment, when the vertical air conditioner indoor unit 10 is turned on, the crossflow fan wheel 130 starts to rotate, and the wind generated by the crossflow fan wheel 130 passes through the air outlet section of the main air duct. Under the action of the diversion component 400 in the first section 113, the wind entering the first section 113 enters the two sub-air ducts respectively, and then blows out from the two sub-air outlets. Two drainage air ducts are provided on the body 100, and the two drainage air ducts are respectively located on the lateral sides of the air outlet. When the two sub-air outlets of the vertical air conditioner indoor unit 10 blow out the heat exchange airflow, negative pressure is formed on both sides of the two sub-air outlets, thereby guiding the airflow of the drainage air ducts on both sides to blow out from the drainage outlet, and the heat exchange airflow is mixed with the airflow with indoor temperature blown out from the drainage outlet, which can significantly reduce the temperature of the heat exchange airflow, and avoid the heat exchange airflow blowing directly to the user without affecting the heat exchange effect, thereby improving the user's comfort.

[0042] In other embodiments of the present invention, the diverter component 400 or the body 100 defines two sub-air outlets in the air outlet.

[0043] In some embodiments of the present invention, Figure 1 As shown, in the direction from front to back, the air outlet section includes a first section 113, a second section 112 and a third section 111 which are connected in sequence, wherein the extension direction of the third section 111 and the extension direction of the first section 113 form an angle.

[0044] In this embodiment, since the extension direction of the first section 113 of the air outlet section and the extension direction of the third section 111 of the air outlet section form an angle, the airflow changes its forward direction in the process of blowing from the third section to the first section. Since the wind flowing in the third section is not uniform, when the airflow blows to the corner of the first section and the third section, it collides with the air duct wall, so that the airflow blown out of the indoor unit of the vertical air conditioner can be more uniform, further improving the user experience.

[0045] In some embodiments of the present invention, Figure 1 As shown, the end of the flow splitter 400 close to the crossflow impeller 130 is a tip, that is, the rear end of the flow splitter is a tip, and the width of the flow splitter increases gradually from the back to the front. The tip of the flow splitter 400 extends into the second section 112 or is adjacent to the second section 112.

[0046] In this embodiment, a section of the flow splitter facing the crossflow impeller 130 is a tip, and the wind entering the first section 113 of the main air duct 110 begins to be split from the tip of the flow splitter, and the flow splitter 400 gradually becomes larger, which can not only reduce the resistance to the wind blowing toward the flow splitter, but also define the air supply direction of the sub-air duct between the flow splitter and the first section 113 of the main air duct 110. Moreover, the tip of the flow splitter is in the second section, and when the crossflow impeller is turned on, the flow splitting will not be uneven because the position of the tip of the flow splitter is too far from the entrance of the first section, and the noise will not be too loud because the position of the tip of the flow splitter is too close to the entrance of the third section.

[0047] In some embodiments of the present invention, Figure 2 As shown, a volute tongue portion 120 located on one side of the duct wall is formed at one end of the third section 111 away from the second section 112. Moreover, in the air outlet direction, the first section 113 is inclined or bent in the direction away from the volute tongue portion 120. In a plane including the tip of the diverter component 400 and parallel to the air outlet, the distance from the duct wall on the side where the volute tongue portion 120 is located to the tip of the diverter component is recorded as the first distance W5. When the distance between the duct walls on both sides of the tip of the diverter component is recorded as the second distance W6, the first distance W5 is equal to 0.41 to 0.45 times the second distance W6. For example, the first distance is equal to 0.41, 0.42, 0.43, 1.44, 0.45 times the second distance.

[0048] The wind from the crossflow impeller 130 is mainly concentrated on one side of the volute, the first section 113 is inclined toward the side of the volute tongue, the wind goes along the third section 111, and when it reaches the second section 112, the wind blows directly on the air duct wall of the second section 112 on the same side as the volute tongue, so most of the wind is concentrated on the same side of the volute tongue 120 of the first section 113. To ensure that the wind diverted by the diversion component is uniform, the first distance is smaller than the second distance.

[0049] Further, in some embodiments of the present invention, Figure 1As shown, the air duct walls on both sides of the third section 111 are planes, and the air duct walls on both sides of the third section 111 are at an angle. Along the air outlet direction of the third section 111, the angle between the air duct walls on both sides of the third section 111 is 18° to 22°, and the air duct walls on both sides of the first section 113 are planes, and the air duct walls on both sides of the first section 113 are at an angle. Along the air outlet direction of the third section 111, the angle between the air duct walls on both sides of the first section 113 is 59° to 64°. The air duct walls on both sides of the second section 112 are arc surfaces, and one of the air duct walls on both sides of the second section 112 is a first air duct wall with an inward concave arc, and the other is a second air duct wall with an outward convex arc. Among them, the fillet radius of the first air duct wall is equal to 0.82 to 0.86 times the fillet radius of the second air duct wall. The above settings define that the third section 111, the second section 112 and the first section 113 are all diffuser sections. Preferably, the air duct walls on both sides of the first section 113 are located on the outer side of the air duct wall corresponding to the second section 112 away from the main air duct 110 .

[0050] In some embodiments of the present invention, Figure 2 As shown, the flow dividing component includes a first guide surface 401 and a second guide surface 402 both connected to the tip. The first guide surface 401 is opposite to the wall surface of the side wind channel wall where the volute tongue portion is located, and the second guide surface 402 is opposite to the wall surface of the side wind channel wall away from the volute tongue portion. The wind channel between the first guide surface 401 and the opposite wind channel wall is the first sub-wind channel 115, and the wind channel between the second guide surface 402 and the opposite wind channel wall is the second sub-wind channel 116. The width of the second sub-wind channel 116 is greater than the width of the first sub-wind channel 115.

[0051] The above-mentioned setting makes the effective widths of the first sub-duct 115 and the second sub-duct 116 different, and the effective width of the first sub-duct is smaller than the effective width of the second sub-duct, thereby making the outlet wind speed of the first sub-air outlet 101 greater than the outlet wind speed of the second sub-air outlet 102, that is, the drainage negative pressure at the first sub-air outlet 101 is greater than the drainage negative pressure at the second sub-air outlet 102, so that the first sub-air duct and the second sub-air duct form an asymmetric drainage channel.

[0052] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the drainage outlet of the first drainage air duct 200 is the first drainage air outlet 202. The drainage outlet of the second drainage air duct 300 is the second drainage air outlet 302. The width W1 of the first drainage air outlet 202 is equal to 0.87 to 0.92 times the width W2 of the second drainage air outlet 302. Since the air flow velocity of the first sub-air outlet 101 is greater than the air flow velocity of the second sub-air outlet 102, the drainage effect of the first sub-air outlet 101 is better than the drainage effect of the second sub-air outlet 102. In order to ensure uniform blowing temperature on both sides in the lateral direction, that is, the drainage amount of the first drainage air duct 200 and the second drainage air duct 300 needs to be consistent, so the width W1 of the first drainage air outlet 202 is set to be equal to 0.87 to 0.92 times the width W2 of the second drainage air outlet 302.

[0053] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the body 100 includes a front surface and side walls connected to the lateral sides of the front surface respectively, the inlet of the first drainage air duct 200 is arranged on the side wall close to the first sub-air outlet 101, and the inlet of the second drainage air duct 300 is arranged on the side wall close to the second sub-air outlet 102. Both side walls of the first drainage air duct 200 are arc-shaped surfaces protruding toward the main air duct. Both side walls of the second drainage air duct 300 are arc-shaped surfaces protruding toward the main air duct. The inlet of the first drainage air duct 200 and the inlet of the second drainage air duct 300 are arranged on the side wall, which can avoid interference with the airflow at the inlet of the main air duct 110 at the rear side wall of the body 100, affecting the drainage effect. Both side walls of the first drainage air duct 200 and the second drainage air duct are protruding toward the main air duct, which is also conducive to the entry of airflow and reduces resistance.

[0054] Further, in some embodiments of the present invention, Figure 1 and Figure 3 As shown, the side wall of the first air flow duct 200 includes a first side wall 203 and a second side wall 204, wherein the second side wall 204 is located on the side of the first side wall 203 close to the main air duct. The radius R1 of the first side wall 203 is equal to 0.71 to 0.75 times the radius R2 of the second side wall 204. When the airflow enters from the inlet of the first air flow duct 200, it blows directly to the second side wall 204. The second side wall 204 is set to have a larger radius to reduce resistance, thereby achieving low resistance and high efficiency of air flow.

[0055] Further, in some embodiments of the present invention, the width H1 of the inlet 201 of the first air flow guiding duct 200 is equal to 2.4 to 2.8 times the width W1 of the first air flow guiding outlet 202. Obviously, the width of the inlet of the first air flow guiding duct 200 being greater than the width of the first air flow guiding outlet 202 is conducive to reducing the resistance of the air flow entering the first air flow guiding duct.

[0056] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the side wall of the second air guiding duct 300 includes a third side wall 303 and a fourth side wall 304, wherein the fourth side wall 304 is located on the side of the third side wall 303 close to the main air duct. The radius R3 of the third side wall 303 is equal to 0.69 to 0.73 times the radius R4 of the fourth side wall 304. When the airflow enters from the inlet 301 of the second air guiding duct 300, it blows directly to the fourth side wall 304. Setting the radius of the fourth side wall 304 larger can also reduce resistance, thereby achieving low resistance and high efficiency of air guiding.

[0057] Further, in some embodiments of the present invention, the width H2 of the inlet 301 of the second air flow guiding duct 300 is equal to 2.5 to 2.9 times the width W2 of the second air flow guiding outlet 302. Obviously, the width of the inlet 301 of the second air flow guiding duct 300 being greater than the width of the second air flow guiding outlet is conducive to reducing the resistance of the airflow entering the second air flow guiding duct.

[0058] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the distance from the rear edge of the inlet 201 of the first drainage duct 200 to the air outlet is the third distance. The width H1 of the inlet of the first drainage duct 200 is equal to 0.27 to 0.32 times the third distance H3. Here, the first distance is large, and the length of the first drainage duct 200 is also large. In other words, in order to reduce the resistance along the airflow entering the first drainage duct 200, the ratio of the inlet of the first drainage duct 200 to the length of the duct is set to ensure the speed of the airflow in the drainage duct.

[0059] In some embodiments of the present invention, the distance from the rear edge of the inlet 301 of the second airflow duct 300 to the air outlet is the fourth distance. The width H2 of the inlet 301 of the second airflow duct 300 is equal to 0.31 to 0.35 times the fourth distance H4.

[0060] Furthermore, in some embodiments of the present invention, the width W1 of the first guide air outlet 202 is equal to 0.38 to 0.42 times the width W3 of the first sub-air outlet 101. This arrangement is conducive to mixing the airflow out of the first sub-air outlet 101 with the airflow out of the first guide air outlet 202.

[0061] The width W2 of the second guide air outlet 302 is equal to 0.38 to 0.42 times the width W4 of the second sub-air outlet 102. This arrangement is conducive to mixing the airflow flowing out of the second sub-air outlet 102 with the airflow flowing out of the second guide air outlet 302.

[0062] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
