[0037] The following is for reference. Figures 1-5 The air guide plate assembly 10 and the air conditioner 100 according to embodiments of the present invention are described.

[0038] Specifically, such as Figure 1 As shown, the air conditioner 100 includes a housing 20, which has an air outlet duct 202 and an air outlet 201 communicating with the air outlet duct 202. The housing 20 also has an air inlet 203, through which airflow enters and exits through the air outlet duct 202 and the air outlet 201. The air conditioner 100 also includes a fan wheel 30, which is disposed within the housing 20 and drives the airflow from the air inlet 203 to the air outlet 201. The air conditioner 100 also includes a heat exchanger 40, which is disposed within the housing 20 and exchanges heat with the airflow. Along the airflow direction, the heat exchanger 40 is located upstream of the fan wheel 30, and the air outlet duct 202 is located downstream of the fan wheel 30. Furthermore, the air conditioner 100 also includes an auxiliary heater 50, which is an electric heater located between the heat exchanger 40 and the fan wheel 30, for auxiliary heating when the air conditioner 100 is in heating mode.

[0039] Under the action of the impeller 30, the airflow enters the housing 20 through the air inlet 203. The airflow first exchanges heat with the heat exchanger 40. After the heat exchange is completed, the airflow flows through the air outlet 202 to the air outlet 201 to achieve indoor cooling or heating.

[0040] like Figure 1 As shown, the air guide plate assembly 10 is located at the air outlet 201 and includes a first air guide plate 1, a second air guide plate 2, and a third air guide plate 3. The first air guide plate 1 is rotatably located at the air outlet 201 to open or close the air outlet 201, and the rotation axis of the first air guide plate 1 is located on the lower side of the air outlet 201. When the first air guide plate 1 opens the air outlet 201, the upper end of the first air guide plate 1 can rotate towards the outside of the air outlet 201, and the end of the first air guide plate 1 that is away from the rotation axis in the width direction forms the air outlet end. The second air guide plate 2 is rotatably located inside the air outlet 201, and the rotation axis of the second air guide plate 2 can be spaced apart from the upper and lower ends of the air outlet 201. The third air guide plate 3 is rotatably disposed at the air outlet 201. The rotation axis of the third air guide plate 3 is located on the upper side of the air outlet 201. When the third air guide plate 3 opens the air outlet 201, the lower end of the third air guide plate 3 can rotate towards the outside of the air outlet 201. The end of the third air guide plate 3 that is away from the rotation axis in the width direction forms the air outlet end.

[0041] When the first air guide plate 1 closes the air outlet 201, the second air guide plate 2 and the third air guide plate 3 are located inside the first air guide plate 1. This allows the second air guide plate 2 and the third air guide plate 3 to be housed inside the first air guide plate 1, making the air conditioner 100 look cleaner when it is off, and preventing the second air guide plate 2 and the third air guide plate 3 from being located on the outside and getting dusty.

[0042] The first air guide plate 1 has multiple first micro-holes, and the third air guide plate 3 has multiple second micro-holes. The first air guide plate 1 and the third air guide plate 3 can be used to achieve a windless mode. While ensuring sufficient airflow for windless cooling, the placement of the first and second micro-holes is unrestricted, improving the effectiveness and airflow of the windless cooling mode. Furthermore, in heating mode, the first air guide plate 1 and the second air guide plate 2 can define the airflow area. The second air guide plate 2 presses the hot airflow downwards, ensuring a downward pressure effect and improving the heating performance.

[0043] According to the air guide plate assembly 10 of this utility model embodiment, by setting a first air guide plate 1, a second air guide plate 2, and a third air guide plate 3, the first air guide plate 1 is rotatably disposed at the air outlet 201 to open or close the air outlet 201. The rotation axis of the first air guide plate 1 is located on the lower side of the air outlet 201. The second air guide plate 2 is rotatably disposed inside the air outlet 201. The third air guide plate 3 is rotatably disposed at the air outlet 201. The rotation axis of the third air guide plate 3 is located on the upper side of the air outlet 201. At the same time, the first air guide plate 1 is provided with a plurality of first micro-holes, and the third air guide plate 3 is provided with a plurality of second micro-holes. The first air guide plate 1 and the third air guide plate 3 can cooperate to better achieve the cooling windless mode and the first air guide plate 1 and the second air guide plate 2 can cooperate to better achieve the heating mode, so that the air conditioner 100 can simultaneously take into account the effects of the heating mode and the cooling windless mode.

[0044] In some embodiments of this utility model, such as Figure 1 As shown, when the first air guide plate 1 closes the air outlet 201, the third air guide plate 3 and the first air guide plate 1 are stacked together, and the second air guide plate 2 is inclined towards the outside of the air outlet 201 in the top-to-bottom direction. This makes the layout of the air guide plate assembly 10 more compact and reasonable.

[0045] Furthermore, such as Figure 1 As shown, the width of the third air guide plate 3 is smaller than the width of the first air guide plate 1. When the first air guide plate 1 closes the air outlet 201, the third air guide plate 3 is located at the upper end of the first air guide plate 1 and is stacked with the upper area of ​​the first air guide plate 1.

[0046] When the first air guide plate 1 closes the air outlet 201, the air conditioner 100 can be in a turned-off state, or it can be in a windless state. When the first air guide plate 1 closes the air outlet 201 and the air conditioner 100 is in a windless state, part of the airflow in the air outlet duct 202 flows out directly through the first micro-hole on the first air guide plate 1, and part of it flows out sequentially through the second micro-hole on the third air guide plate 3 and the first micro-hole on the first air guide plate 1, thus better dispersing the airflow.

[0047] In some specific examples of this utility model, the air conditioner 100 has a heating mode, such as... Figure 2 As shown, in heating mode, one end of the second air guide plate 2 in the width direction abuts against or is close to the upper sidewall of the air outlet duct 202. An air outlet area is defined between the first air guide plate 1 and the second air guide plate 2. The third air guide plate 3 is located on the side of the second air guide plate 2 away from the first air guide plate 1. The hot airflow from the air outlet duct 202 flows out through the air duct between the first air guide plate 1 and the second air guide plate 2.

[0048] The second air guide plate 2 is tilted downwards towards the outer side of the air outlet 201, which can better press the hot air downwards, causing the hot air to blow downwards and then slowly rise, thus improving the heating effect. In addition, since the second air guide plate 2 does not have a microporous structure, it can better press the hot air downwards and prevent the hot air from flowing upwards through the micropores, further improving the heating effect.

[0049] In heating mode, the first air guide plate 1 rotates outward to its maximum angle, the third air guide plate 3 remains in the off state, and the second air guide plate 2 rotates to the optimal heating position. Figure 1 and Figure 2 In the example shown, the two ends of the second air guide plate 2 in the width direction are the first end and the second end. In the off state, the first end is located on the side of the second end away from the air outlet 201. In the heating mode, the second end of the second air guide plate 2 rotates upward, and the second end is located on the side of the first end away from the air outlet 201 and abuts or approaches the upper side wall of the air outlet duct 202 to define the air outlet area with the first air guide plate 1.

[0050] It should be noted that the distance between the second end of the second air guide plate 2 and the rotation axis of the second air guide plate 2 is less than or equal to the distance between the second end and the lower end of the third air guide plate 3 when the machine is off, which facilitates the rotation of the second air guide plate 2.

[0051] In some embodiments of this utility model, the air conditioner 100 has a cooling windless mode, such as... Figure 3 As shown, in the cooling windless mode, one end of the first air guide plate 1 and one end of the third air guide plate 3 in the width direction are spliced ​​together, and the second air guide plate 2 is tilted towards the outside of the air outlet 201 in the top-to-bottom direction.

[0052] When switching to the cooling windless mode from the off state, the upper end of the first air guide plate 1 and the lower end of the third air guide plate 3 both rotate outwards towards the air outlet 201 until the upper end of the first air guide plate 1 and the lower end of the third air guide plate 3 are joined or overlapped. The second air guide plate 2 can rotate to the optimal cooling position. At this time, the airflow in the air outlet duct 202 flows to the air outlet 201 and then flows out through the first micro-hole on the first air guide plate 1 and the third micro-hole on the third air guide plate 3. Since the third air guide plate 3 does not need to consider the heating air pressure issue, the second micro-hole on the third air guide plate 3 can be set in any form, making the cooling windless mode more effective and the air volume larger.

[0053] In addition, in the windless cooling mode, after the indoor temperature stabilizes, the second air guide plate 2 can swing up and down to achieve air disturbance in the windless mode.

[0054] In some embodiments of this utility model, the air conditioner 100 has a heating windless mode, such as... Figure 4As shown, in the heating windless mode, one end of the second air guide plate 2 in the width direction abuts against or is close to the upper side wall of the air outlet duct 202, the first air guide plate 1 and the second air guide plate 2 define the air outlet area, the third air guide plate 3 is located on the side of the second air guide plate 2 away from the first air guide plate 1, and the air outlet end of the first air guide plate 1 is tilted upward.

[0055] The positions of the second air guide plate 2 and the third air guide plate 3 can be the same as those of the second air guide plate 2 and the third air guide plate 3 in the heating mode. The air outlet of the first air guide plate 1 is tilted upward. The second air guide plate 2 presses the hot air flow towards the first air guide plate 1 downward. The hot air flow after being pressed down can flow out through the first micro hole on the first air guide plate 1, and make the hot flow blow downward, which can better realize the heating windless mode.

[0056] Specifically, during the adjustment to achieve a draft-free heating effect, the first air guide plate 1 can be rotated outward by a first angle. At this time, the air outlet of the first air guide plate 1 can be located on the side of the extension line of the air outlet of the second air guide plate 2 closer to the air outlet 201. Under the downward pressure of the second air guide plate 2, part of the airflow in the air outlet duct 202 flows out directly, and part flows out through the first micro-hole of the first air guide plate 1, thus reducing the draft while ensuring the heating effect. After the indoor temperature stabilizes, the first air guide plate 1 is rotated to a second angle, which is smaller than the first angle. At this time, the extension line of the air outlet of the second air guide plate 2 intersects with the first air guide plate 1. Under the downward pressure of the second air guide plate 2, most of the airflow in the air outlet duct 202 will flow out through the first micro-hole on the first air guide plate 1, thereby further reducing the draft.

[0057] In some embodiments of this utility model, the air conditioner 100 has a cooling mode, such as... Figure 5 As shown, in cooling mode, the first air guide plate 1 and the third air guide plate 3 are located on the upper and lower sides of the air outlet 201, respectively. In the direction from top to bottom, the second air guide plate 2 is inclined towards the outside of the air outlet 201. This allows the cold air to be blown out of the air outlet 201 more effectively, and the second air guide plate 2 guides and diverts the cold air.

[0058] Furthermore, such as Figure 5 As shown, in cooling mode, the third air guide plate 3 is located above the extension line of the upper side wall of the air outlet duct 202. This prevents the third air guide plate 3 from affecting the upward blowing of cold air and avoids airflow loss caused by wind obstruction. Furthermore, when the first air guide plate 1 is rotated outward to its maximum angle and the second air guide plate 2 is rotated to the optimal cooling position, the airflow can be better guided by the first air guide plate 1 and the second air guide plate 2, ensuring the effectiveness of cooling airflow.

[0059] In some embodiments of this invention, the diameter of the second micropore is larger than the diameter of the first micropore. For example... Figure 3As shown, in the windless cooling mode, the third air guide plate 3 is located above the first air guide plate 1. Most of the air blown out through the third air guide plate 3 is blown upwards at an angle, making it less likely to blow directly on the user. This makes the aperture of the second micro-hole larger than that of the first micro-hole, which not only increases the air volume on the third air guide plate 3, but also avoids blowing directly on the user, thus achieving a greater cooling capacity and a windless feeling.

[0060] In some embodiments of this invention, at least two of the multiple second micro-holes extend in different directions. This allows the third air guide plate 3 to disperse air in different directions, thus achieving a better windless mode.

[0061] Further, along the length of the third air guide plate 3, the third air guide plate 3 sequentially includes a first region, a second region, and a third region. Along the thickness direction of the third air guide plate 3, the second micro-holes located in the first region and the second micro-holes located in the third region are inclined in directions away from each other. The second micro-holes in the second region extend along the thickness direction of the third air guide plate 3. In a specific example, the air outlet 201 extends horizontally and horizontally. In the direction from the inner to the outer side of the air outlet 201, along the thickness direction of the third air guide plate 3, the first micro-hole in the first region is inclined to the left, the second micro-hole in the third region is inclined to the right, and the second micro-hole in the second region extends along the thickness direction of the third air guide plate 3. The air from the first region blows upward to the left, the air from the third region blows upward to the right, and the air from the second region blows diagonally upward. The first region can be located to the left of the second region and the third region to the right of the second region, or the first region can be located to the right of the second region and the third region to the left of the second region.

[0062] In some embodiments of this utility model, the thickness of the third air guide plate 3 is 4mm-8mm. For example, the thickness of the third air guide plate 3 can be 4mm, 5mm, 6mm, 7mm, or 8mm, etc. This increases the length of the second micro-hole on the third air guide plate 3, thereby improving the air dispersion effect.

[0063] In some embodiments of this utility model, the two ends of the third air guide plate 3 along its length are flush with the two ends of the first air guide plate 1 along its length. It is understood that the length of the third air guide plate 3 is the same as the length of the first air guide plate 1, and the two ends of the third air guide plate 3 along its length are flush with the two ends of the first air guide plate 1 along its length. This increases the overlap effect of the first air guide plate 1 and the third air guide plate 3 in the windless cooling mode, improving the windless effect, and also makes the overlap between the first air guide plate 1 and the second air guide plate 2 more aesthetically pleasing.

[0064] In some embodiments of this utility model, the two ends of the air outlet 201 along its length are spaced apart from the housing 20. The first air guide plate 1 is located outside the air outlet 201, extending from one end of the housing 20 to the other along the length of the air outlet 201. This increases the length of the first air guide plate 1 and improves its air guiding effect. Additionally, a third air guide plate 3 is also located outside the air outlet 201, extending from one end of the housing 20 to the other along the length of the air outlet 201, with both ends of the third air guide plate 3 flush with the two ends of the first air guide plate 1 along its length.

[0065] The air conditioner 100 according to an embodiment of the present invention is described below.

[0066] An air conditioner 100 according to an embodiment of the present invention includes a housing 20 and the aforementioned air guide plate assembly 10.

[0067] like Figure 1 As shown, the housing 20 has an air outlet duct 202 and an air outlet 201 communicating with the air outlet duct 202. The housing 20 also has an air inlet 203, through which airflow enters and exits through the air outlet duct 202 and the air outlet 201. The air conditioner 100 also includes a fan wheel 30, which is disposed within the housing 20 and drives the airflow from the air inlet 203 to the air outlet 201. The air conditioner 100 also includes a heat exchanger 40, which is disposed within the housing 20 and exchanges heat with the airflow. Along the airflow direction, the heat exchanger 40 is located upstream of the fan wheel 30, and the air outlet duct 202 is located downstream of the fan wheel 30. Furthermore, the air conditioner 100 also includes an auxiliary heater 50, which is an electric heater located between the heat exchanger 40 and the fan wheel 30, for auxiliary heating when the air conditioner 100 is in heating mode.

[0068] Under the action of the impeller 30, the airflow enters the housing 20 through the air inlet 203. The airflow first exchanges heat with the heat exchanger 40. After the heat exchange is completed, the airflow flows through the air outlet 202 to the air outlet 201. Under the guidance of the air guide plate assembly 10, it flows into the room to achieve indoor cooling or heating.

[0069] According to the embodiment of the present utility model, the air conditioner 100, by setting the above-mentioned air guide plate assembly 10, includes a first air guide plate 1, a second air guide plate 2, and a third air guide plate 3. The first air guide plate 1 is rotatably disposed at the air outlet 201 to open or close the air outlet 201.
