[0036] The housing assembly 10 of the air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 3 As shown, the housing assembly 10 of the air conditioner 100 according to the embodiment of the present utility model includes a housing 1 and a switch door 3 .

[0038] Specifically, refer to the attached Figure 1 and attached Figure 3 As shown, the housing 1 can protect the air conditioner 100 structure inside the housing assembly 10, preventing the air conditioner 100 structure inside the housing assembly 10 from being exposed and damaged, which is beneficial to prolonging the service life of the air conditioner 100 and has a good appearance. Figure 1 and attached Figure 3As shown, the shell 1 has a main air duct 11, an auxiliary air duct 12, and an air inlet 111 and an air outlet 112 connected to the main air duct 11. The airflow outside the shell assembly 10 can enter the main air duct 11 through the air inlet 111, and then blow into the room through the air outlet 112 to adjust the indoor temperature.

[0039] Further, see Appendix Figure 1 and attached Figure 3 As shown, the width direction of the air outlet 112 (see attached Figure 1 At least one side of the air outlet 112 (in the direction h shown in the figure) is provided with an auxiliary air duct 12, and the auxiliary air duct 12 has a first port 123 located on the outer wall of the shell 1 and a second port 124 located on the inner wall of the main air duct 11. The setting of the auxiliary air duct 12 can connect the outside of the shell assembly 10 and the main air duct 11, so that the airflow of the main air duct 11 flows out of the air conditioner 100 or the airflow outside the air conditioner 100 flows into the main air duct 11, which can increase the circulating air volume and increase the indoor air circulation. For example, the auxiliary air duct 12 can be provided on only one side of the air outlet 112 in the width direction, or the auxiliary air duct 12 can be provided on both sides of the air outlet 112 in the width direction.

[0040] Further, see the attached Figure 1 and attached Figure 3 As shown, the switch door 3 can be movably arranged at the air outlet 112, and is used for opening or closing the air outlet 112. The setting of the switch door 3 can ensure the normal air outlet of the air conditioner 100 when the air conditioner 100 is in normal use. When the air conditioner 100 is out of use, it can reduce the dust, debris, etc. from entering the air conditioner 100, thereby reducing the cleaning frequency and maintenance frequency of the air conditioner 100.

[0041] Further, see Attachment Figure 1 and attached Figure 2 As shown, the switch door 3 is provided with a plurality of spaced micro holes 31 for the airflow in the main air duct 11 to flow out from the air outlet 112. The design of the micro holes 31 can disperse the airflow when it flows through, achieving a certain degree of windless design, making the blown airflow more comfortable. Figure 1 and attached Figure 2 As shown, the angle between the axis f of the micro hole 31 and the axis g of the air outlet 112 is C, and satisfies: 18°≤C≤22°, which can prevent the air conditioner 100 from Figure 1The air volume (as shown) is too concentrated, which can greatly reduce the front air outlet speed of the air conditioner 100, improve the windless design effect of the air conditioner 100, take into account the problem of cold wind protection for children, meet the user's demand for windless use, reduce the probability of users experiencing discomfort symptoms such as air conditioning disease, improve the user's comfort, and increase the air supply angle at the air outlet 112 to improve the cooling effect of the air conditioner 100. At the same time, it can also avoid the air outlet 112 from sucking the airflow at the first port 123. For example, the angle C between the axis f of the micropore 31 and the axis g of the air outlet 112 can be 18°, 19°, 20°, 21° or 22°.

[0042] It is understandable that when the air conditioner 100 is in cooling mode, when the door 3 closes the air outlet 112, Figure 1 As shown, the auxiliary air duct 12 is used for the air flow in the main air duct 11 to flow out of the housing 1. The cold air flow in the main air duct 11 can directly flow out of the air conditioner 100 through the multiple micropores 31 on the switch door 3, or flow into the auxiliary air duct 12 through the second port 124, and then flow out of the air conditioner 100 through the first port 123, which can increase the air volume of the air conditioner 100 while realizing a windless design, improve the cooling effect of the air conditioner 100, and improve the user experience; when the switch door 3 opens the air outlet 112, refer to the attached Figure 3 As shown, the auxiliary air duct 12 is used for the air flow outside the shell 1 to enter the main air duct 11, so that the indoor normal temperature air flow outside the shell 1 flows into the auxiliary air duct 12 from the first port 123, and then flows to the main air duct 11 through the second port 124, and then mixes with the cold air flow in the main air duct 11, which can reduce the temperature of the air flow blown out from the air outlet 112, reduce the feeling of cold wind blowing, improve the user's comfort, improve the user experience, and can increase the circulating air volume and increase the indoor air circulation.

[0043] Optionally, an air inlet grille can be provided at the air inlet 111. On the one hand, the air inlet grille can prevent hands or other foreign objects from reaching into the interior of the shell 1, thereby protecting the safety of the user and ensuring the normal operation of the air conditioner 100. On the other hand, the air inlet grille can prevent insects, mice, etc. from entering the shell assembly 10 of the air conditioner 100 and causing damage to the air conditioner 100, thereby ensuring the beautiful appearance of the shell assembly 10 and guaranteeing the normal operation of the air conditioner 100.

[0044] Optionally, the air conditioner 100 may be a wall mounted air conditioner or a cabinet air conditioner. The following description will be made by taking the air conditioner 100 as a cabinet air conditioner as an example.

[0045] According to the shell assembly 10 of the air conditioner 100 in the embodiment of the utility model, a switch door 3 is provided at the air outlet 112, and the switch door 3 can be moved to open or close the air outlet 112. A plurality of spaced microholes 31 are provided on the switch door 3, and the angle C between the axis of the microhole 31 and the axis of the air outlet 112 satisfies: 18°≤C≤22°. This can prevent the air volume in front of the air conditioner 100 from being too concentrated, can greatly reduce the air outlet speed at the front of the air conditioner 100, improve the windless design effect of the air conditioner 100, take into account the problem of children's cold wind protection, meet the user's demand for windless use, reduce the probability of users experiencing discomfort symptoms such as air-conditioning disease, improve the user's comfort, and can increase the air supply angle at the air outlet 112 to improve the cooling effect of the air conditioner 100. At the same time, by providing an auxiliary air duct 12 on at least one side in the width direction of the air outlet 112, the auxiliary air duct 12 has a first port 123 located on the outer wall of the shell 1 and a second port 124 located on the inner wall of the main air duct 11, which can connect the outside of the shell assembly 10 and the main air duct 11, so that the cold air flow in the main air duct 11 can directly flow out of the air conditioner 100 through the multiple micropores 31 on the switch door 3, and can also flow into the auxiliary air duct 12 through the second port 124, and then flow out of the air conditioner 100 through the first port 123. While achieving a windless design, the air volume of the air conditioner 100 can be increased, the cooling effect of the air conditioner 100 can be improved, and the user experience can be improved.

[0046] In some embodiments of the present invention, refer to the attached Figure 1 As shown, the distance between the first port 123 and the end of the air outlet 112 close to each other is L1, and satisfies: L1 ≥ 45mm, so as to ensure that the spacing between the first port 123 and the air outlet 112 is appropriate, and ensure the normal air outlet of the air outlet 112 and the normal air intake and air outlet of the auxiliary air duct 12. It can be understood that if L1 < 45mm, that is, the distance between the first port 123 and the air outlet 112 is too close, it is easy to cause the airflow at the first port 123 to merge with the airflow at the air outlet 112, so that the cold air flow flowing out of the auxiliary air duct 12 flows to the front of the air conditioner 100, causing the cold air flow to be too concentrated in the front and resulting in excessive wind speed, affecting the windless design effect of the air conditioner 100 and reducing the comfort of the user. For example, the distance L1 between the first port 123 and the end of the air outlet 112 close to each other can be 45mm, 46mm, 47mm, 48mm, 49mm or 50mm.

[0047] Further, see Attachment Figure 1As shown, the distance between the first port 123 and the end of the air inlet 111 close to each other is L2, and satisfies: L2 ≥ 45mm, so as to ensure that the distance between the first port 123 and the air inlet 111 is appropriate, and to ensure the normal air intake of the air inlet 111 and the normal air outlet of the auxiliary air duct 12. It can be understood that if L2 < 45mm, that is, the distance between the first port 123 and the air inlet 111 is too close, it is easy to cause the airflow at the first port 123 to be sucked by the airflow at the air inlet 111, so that the cold airflow flowing out of the auxiliary air duct 12 flows into the air inlet 111 again, causing the cold airflow flowing out of the auxiliary air duct 12 to affect the normal air intake at the air inlet 111, affecting the cooling effect of the air conditioner 100, causing the airflow to be turbulent and the design of the auxiliary air duct 12 to be invalid. For example, the distance L2 between the first port 123 and the end of the air inlet 111 close to each other can be 45mm, 46mm, 47mm, 48mm, 49mm or 50mm.

[0048] It should be noted that the airflow in the main air duct 11 is driven by the kinetic energy provided by the wind wheel 30 to flow along the main air duct 11 to the outside of the housing 1. When the airflow just leaves the wind wheel 30, the speed is high and the pressure is low. When the airflow flows to the air outlet 112, due to the existence of the switch door 3, the airflow is blocked from flowing out of the air conditioner 100 from the air outlet 112 to a certain extent. According to the Bernoulli equation, the kinetic energy is converted into pressure potential energy, the speed decreases and the pressure increases, so that the air duct pressure at the air outlet 112 is greater than the pressure at the auxiliary air duct 12. Therefore, the airflow at the auxiliary air duct 12 enters the auxiliary air duct 12 from the second port 124 and flows out of the air conditioner 100 from the first port 123. The reason for the entrainment is that compared with the air outlet 112 and the air inlet 111 of the main air duct 11, the air volume of the auxiliary air duct 12 is much smaller, and the flow rate is also much smaller. Because the pressure is low where the flow rate is high, the airflow will be sent to the position with low pressure due to the existence of the pressure difference, so there will be entrainment.

[0049] In some embodiments of the present invention, refer to the attached Figure 1 As shown, the width of the secondary air duct 12 is L3, and satisfies: L3 ≥ 20 mm, so as to ensure the normal air outlet of the secondary air duct 12, and avoid excessive pressure loss along the way due to obstacles in the secondary air duct 12, uneven inner wall of the secondary air duct 12, or too narrow first port 123, which affects the normal air outlet in the secondary air duct 12. For example, the width L3 of the secondary air duct 12 can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm or 25 mm. It can be understood that because the width L3 of the secondary air duct 12 is ≥ 20 mm, the widths of the first port 123 and the second port 124 are also greater than or equal to 20 mm, which can ensure that the airflow in the main air duct 11 can enter the secondary air duct 12 normally through the second port 124, and the airflow in the secondary air duct 12 flows normally and flows out from the first port 123.

[0050] In some embodiments of the present invention, Figure 3 As shown, on a cross section perpendicular to the length direction of the air outlet 112, the inner wall of the main air duct 11 which is on the same side as the second port 124 and located downstream of the second port 124 along the air flow direction of the main air duct 11 is retracted to the extension line or tangent line of the end of the second port 124 away from the air outlet 112. This can avoid the inner wall of the main air duct 11 which is on the same side as the second port 124 and located downstream of the second port 124 along the air flow direction of the main air duct 11 being higher than the extension line or tangent line of the end of the second port 124 away from the air outlet 112 when the air flow in the main air duct 11 flows from the air inlet 111 to the air outlet 112. This can avoid the inner wall of the main air duct 11 which is on the same side as the second port 124 and located downstream of the second port 124 along the air flow direction of the main air duct 11 affecting the normal flow of the airflow, thereby ensuring that the airflow flows more smoothly, and further ensuring the air inducing effect of the auxiliary air duct 12.

[0051] In a further embodiment of the present invention, referring to the attached Figure 3 As shown, the shortest distance between the inner wall of the main air duct 11 on the same side as the second port 124 and located downstream of the second port 124 along the airflow direction of the main air duct 11 and the extension line or tangent line of the end of the second port 124 away from the air outlet 112 is L4, and satisfies: L4 ≥ 2mm, so as to avoid the inner wall of the main air duct 11 on the same side as the second port 124 and located downstream of the second port 124 along the airflow direction of the main air duct 11 being higher than the stagnation point of the extension line or tangent line of the end of the second port 124 away from the air outlet 112, and avoid the inner wall of the main air duct 11 on the same side as the second port 124 and located downstream of the second port 124 along the airflow direction of the main air duct 11 affecting the normal flow of the airflow, thereby ensuring a smoother flow of the airflow, and further ensuring the air-inducing effect of the auxiliary air duct 12. For example, L4 can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm or 2.5mm.

[0052] In a specific example, see the attached Figure 3As shown, both sides of the air outlet 112 in the width direction are provided with auxiliary air ducts 12, and the two auxiliary air ducts 12 are respectively a first auxiliary air duct 121 and a second auxiliary air duct 122. The second opening 124 of the first auxiliary air duct 121 divides the inner wall of the main air duct 11 on the same side into a first inner wall 114 and a second inner wall 115. The first inner wall 114 is located on the side of the second inner wall 115 away from the air outlet 112. On the cross section perpendicular to the length direction of the air outlet 112, the extension line of the first inner wall 114 is a, and the distance between the second inner wall 115 and a is The shortest distance is greater than 2 mm; the second outlet 124 of the second auxiliary air duct 122 divides the inner wall of the main air duct 11 on the same side into a third inner wall 116 and a fourth inner wall 117, and the third inner wall 116 is located on the side of the fourth inner wall 117 away from the air outlet 112. On the cross section perpendicular to the length direction of the air outlet 112, the tangent of the inner wall of the main air duct 11 with the end of the second outlet 124 of the second auxiliary air duct 122 away from the air outlet 112 as the tangent point is b, and the shortest distance between the fourth inner wall 117 and b is greater than 2 mm.

[0053] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 3 As shown, both sides of the air outlet 112 in the width direction are provided with auxiliary air ducts 12, and the second ports 124 of the two auxiliary air ducts 12 are arranged at intervals along the airflow direction of the main air duct 11, and air can be discharged from the main air duct 11 to the outside of the shell 1 from both sides of the air conditioner 100 along the width direction of the air outlet 112, thereby increasing the air outlet path of the air conditioner 100, being able to increase the air outlet volume of the air conditioner 100 while realizing a windless design, thereby improving the cooling effect of the air conditioner 100 and improving the user experience.

[0054] In a further embodiment of the present invention, refer to the attached Figure 1 and attached Figure 3 As shown, the width direction of the main air duct 11 (refer to the attached Figure 1 The inner wall on one side (in the h direction shown in the figure) has a volute tongue portion 113. Among the two auxiliary air ducts 12, the one located on the same side of the main air duct 11 in the width direction as the volute tongue portion 113 is the first auxiliary air duct 121, and the one located on the opposite side of the main air duct 11 in the width direction as the volute tongue portion 113 is the second auxiliary air duct 122. The second port 124 of the first auxiliary air duct 121 is located downstream of the second port 124 of the second auxiliary air duct 122, so that the airflow in the main air duct 11 first flows out from the second port 124 of the second auxiliary air duct 122, and then flows out from the second port 124 of the first auxiliary air duct 121, and the remaining part flows out from the air outlet 112, so as to prevent the airflow in the main air duct 11 from flowing to the auxiliary air ducts 12 at different positions at the same time, causing airflow turbulence, thereby ensuring the normal flow of the airflow in the main air duct 11 and the normal air outlet at the air outlet 112.

[0055] In a further embodiment of the present invention, refer to the attached Figure 1 and attached Figure 3 As shown, the first opening 123 of the first auxiliary air duct 121 has a width direction (see the attached Figure 3 Guide plates 125 are provided at both ends of the first auxiliary air duct 121 and the second auxiliary air duct 121. The guide plates 125 extend toward the first auxiliary air duct 121 and away from the air outlet 112. The arrangement of the guide plates 125 can play a guiding role, so that the airflow in the first auxiliary air duct 121 is along the extension direction of the guide plates 125 (see the attached Figure 3 The airflow at the first outlet 123 of the first auxiliary air duct 121 is prevented from being sucked by the airflow at the air outlet 112, thereby ensuring the normal air outlet of the first auxiliary air duct 121 and the air outlet 112.

[0056] In a further embodiment of the present invention, refer to the attached Figure 1 As shown, the width of the guide plate 125 is D, and satisfies: D ≥ 30 mm, which can further ensure the guiding effect of the guide plate 125, so that the airflow in the first auxiliary air duct 121 flows out from the first port 123 along the extension direction of the guide plate 125. For example, the width D of the guide plate 125 can be 30 mm, 31 mm, 32 mm, 33 mm, 34 mm or 35 mm.

[0057] In a further embodiment of the present invention, refer to the attached Figure 1 As shown, the angle between the guide plate 125 and the width direction of the air outlet 112 is A, the second auxiliary air duct 122 extends in a direction away from the air outlet 112, and the angle between the line connecting the centers of the first port 123 and the second port 124 of the second auxiliary air duct 122 and the width direction of the air outlet 112 is B, and satisfies: A=B, 15°≤A≤25°, which can further prevent the airflow at the first port 123 of the first auxiliary air duct 121 and the second auxiliary air duct 122 from being sucked by the airflow at the air outlet 112, and ensure the normal air discharge of the first auxiliary air duct 121, the second auxiliary air duct 122 and the air outlet 112. For example, the angle A between the guide plate 125 and the width direction of the air outlet 112 and the angle B between the line connecting the centers of the first port 123 and the second port 124 of the second auxiliary air duct 122 and the width direction of the air outlet 112 can be 15°, 18°, 20°, 21°, 23° or 25°.

[0058] It can be understood that if A=B<15°, it is easy to cause the airflow at the first port 123 to be sucked by the airflow at the air inlet 111, especially the airflow at the first port 123 of the first sub-air duct 121 is more easily sucked by the airflow at the air inlet 111, so that the cold air flow flowing out of the sub-air duct 12 flows into the air inlet 111 again, forming a larger vortex, causing the cold air flow flowing out of the sub-air duct 12 to affect the normal air intake at the air inlet 111, affecting the cooling effect of the air conditioner 100, causing airflow turbulence and the design of the sub-air duct 12 to be invalid; if A=B>25°, it is easy to cause the airflow at the first port 123 to be sucked by the airflow at the air outlet 112, so that the cold air flow flowing out of the sub-air duct 12 flows to the front of the air conditioner 100, causing the cold air flow to be too concentrated in the front and resulting in excessive wind speed, affecting the windless design effect of the air conditioner 100, reducing the user's comfort, and failing to achieve the purpose of expanding the air outlet angle.

[0059] Preferably, refer to the attached Figure 1 and attached Figure 3 As shown, in the cross section perpendicular to the length direction of the air outlet 112 , the contour of the second sub-air duct 122 is arc-shaped, which can make the air flow smoother and ensure the air outlet effect of the second sub-air duct 122 .

[0060] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 3 As shown, the shell assembly 10 of the air conditioner 100 also includes a guide member 2, which is located at the air outlet 112 and is separated from the two ends of the air outlet 112 in the width direction. In the process of the air flow flowing from the air inlet 111 to the air outlet 112, the setting of the guide member 2 can divert the air flow in the main air duct 11, so that the air flow is divided into two streams and blown out in different directions, so as to increase the air outlet area of ​​the air conditioner 100 and improve the cooling and heating effects of the air conditioner 100.

[0061] Further, see Attachment Figure 1 As shown, there are two switch doors 3 and they are respectively located on both sides of the guide member 2 along the width direction of the air outlet 112. Each switch door 3 is provided with a plurality of micropores 31. Along the airflow flow direction of the main air duct 11, the axes f of the micropores 31 on the two switch doors 3 are inclined in directions away from each other, so that the airflow divided into two streams by the guide member 2 can be blown out in two directions respectively, thereby reducing the air volume blown in front of the air conditioner 100, greatly reducing the air outlet speed of the air conditioner 100, improving the windless design effect of the air conditioner 100, taking into account the problem of children's protection from cold wind, meeting the user's demand for windless use, reducing the probability of users experiencing discomfort symptoms such as air-conditioning disease, improving the user's comfort, and increasing the air supply angle at the air outlet 112 to improve the cooling effect of the air conditioner 100.

[0062] In a further embodiment of the present invention, refer to the attached Figure 1 and attached Figure 3 As shown, air outlet grilles 23 are provided on both sides of the guide member 2 along the width direction of the air outlet 112. On the one hand, the air outlet grilles 23 can prevent hands or other foreign objects from reaching into the interior of the shell 1, thereby protecting the safety of the user and ensuring the normal operation of the air conditioner 100; on the other hand, the air outlet grilles 23 can prevent insects, mice and the like from entering the shell assembly 10 of the air conditioner 100 and causing damage to the air conditioner 100, thereby ensuring the beautiful appearance of the shell assembly 10 and ensuring the normal operation of the air conditioner 100. At the same time, the setting of the air outlet grilles 23 can also disperse the airflow when the airflow passes through, thereby achieving a certain degree of windless design, making the blown airflow more comfortable.

[0063] In a further embodiment of the present invention, referring to the attached Figure 3 As shown, the guide member 2 has a guide wall 21 facing the first auxiliary air duct 121, the minimum distance between the end of the second port 124 of the first auxiliary air duct 121 away from the air outlet 112 and the plane where the guide wall 21 is located is L5, and the minimum distance between the end of the second port 124 of the first auxiliary air duct 121 close to the air outlet 112 and the plane where the guide wall 21 is located is L6, and it satisfies: L5<L6, through the difference in distance between the two ends of the second port 124 of the first auxiliary air duct 121 and the plane where the guide wall 21 is located, a low pressure area is formed at the position of the second port 124 of the first auxiliary air duct 11, so that the first auxiliary air duct There is a pressure difference between the second port 124 and the first port 123 of 121, and the pressure at the second port 124 is lower than the pressure at the first port 123, thereby realizing passive drainage. When the switch door 3 opens the air outlet 112, due to the pressure difference between the first port 123 and the second port 124, the indoor normal temperature airflow outside the shell 1 automatically enters the first sub-air duct 121 from the first port 123, and flows from the second port 124 to the main air duct 11 and mixes with the cold air flow in the main air duct 11, which can reduce the temperature of the airflow blown out from the air outlet 112, reduce the feeling of cold wind blowing, improve the user's comfort, and improve the user's experience.

[0064] In a specific example, the pressure of the indoor air flow is atmospheric pressure, which is approximately 1013225 Pa, and the pressure difference between the second port 124 and the first port 123 is 10 Pa, thereby realizing passive drainage of the secondary air duct 12 .

[0065] Further, see Attachment Figure 3As shown, the guide member 2 also has a second guide wall 22 facing the second sub-air duct 122, and the guide wall 21 is connected to one end of the second guide wall 22 facing the air inlet 111. Along the flow direction of the airflow, the distance between the guide wall 21 and the second guide wall 22 gradually increases. When the airflow flows through the guide member 2, the guide member 2 diverts the airflow in the main air duct 11, and the diverted airflow flows along the guide wall 21 and the second guide wall 22 to the air outlet 112 respectively, so that the airflow is divided into two streams and blown out in different directions, so as to increase the air outlet area of ​​the air conditioner 100 and improve the cooling effect and heating effect of the air conditioner 100.

[0066] In a further embodiment of the present invention, referring to the attached Figure 3 As shown, the minimum distance between the end of the second opening 124 of the second auxiliary air duct 122 facing away from the air outlet 112 and the wall surface on the inner wall of the main air duct 11 connected to the first auxiliary air duct 121 is L7, and the minimum distance between the end of the second opening 124 of the second auxiliary air duct 122 close to the air outlet 112 and the wall surface on the inner wall of the main air duct 11 connected to the first auxiliary air duct 121 is L8, and it satisfies: L7<L8, through the difference in distance between the two ends of the second opening 124 of the second auxiliary air duct 122 and the wall surface on the inner wall of the main air duct 11 connected to the first auxiliary air duct 121, a low pressure area is formed at the position of the second opening 124 of the second auxiliary air duct 122 of the main air duct 11 , so that there is a pressure difference between the second port 124 and the first port 123 of the second sub-air duct 122, and the pressure at the second port 124 is lower than the pressure at the first port 123, thereby realizing passive drainage. When the switch door 3 opens the air outlet 112, due to the pressure difference between the first port 123 and the second port 124, the indoor normal temperature airflow outside the shell 1 automatically enters the second sub-air duct 122 from the first port 123, and flows from the second port 124 to the main air duct 11 and mixes with the cold airflow in the main air duct 11, which can reduce the temperature of the airflow blown out from the air outlet 112, reduce the feeling of cold wind blowing, improve the user's comfort, and improve the user's experience.

[0067] The present invention further provides an air conditioner 100 having the housing assembly 10 of the air conditioner 100 according to the above embodiment.

[0068] like Figure 1 and Figure 3 As shown, the air conditioner 100 according to the embodiment of the present invention includes a heat exchanger 20 , a wind wheel 30 and the housing assembly 10 of the air conditioner 100 described above.

[0069] Specifically, refer to the attached Figure 1 and attached Figure 3As shown, the heat exchanger 20 and the wind wheel 30 are arranged in the main air duct 11. Along the flow direction of the airflow, the heat exchanger 20 is arranged upstream of the wind wheel 30. The wind wheel 30 can drive the airflow outside the air conditioner 100 to enter the main air duct 11 through the air inlet 111. The airflow in the main air duct 11 can exchange heat with the heat exchanger 20. The airflow after heat exchange can be blown into the room through the air outlet 112, thereby achieving the effect of adjusting the indoor temperature and meeting the user's use needs. In a specific example, refer to the attached Figure 1 and attached Figure 3 As shown, the wind wheel 30 is a single-flow wind wheel.

[0070] It should be noted that the reference Figure 1 and attached Figure 3 As shown, part of the input pipe and the output pipe of the heat exchanger 20 are arranged in the first auxiliary air duct 121 to facilitate the arrangement of the internal structure of the air conditioner 100.

[0071] According to the air conditioner 100 of the embodiment of the utility model, by providing the shell assembly 10 of the air conditioner 100 mentioned above, by providing a switch door 3 at the air outlet 112, the switch door 3 can move to open or close the air outlet 112, and a plurality of spaced micro holes 31 are provided on the switch door 3, and the angle C between the axis of the micro hole 31 and the axis of the air outlet 112 satisfies: 18°≤C≤22°, which can prevent the air volume in front of the air conditioner 100 from being too concentrated, can greatly reduce the air outlet speed of the air conditioner 100 at the front, improve the windless design effect of the air conditioner 100, take into account the problem of children's cold wind protection, meet the user's demand for windless use, reduce the probability of users experiencing discomfort symptoms such as air-conditioning disease, improve the user's comfort, and can increase the air supply angle at the air outlet 112 to improve the cooling effect of the air conditioner 100. At the same time, by providing an auxiliary air duct 12 on at least one side in the width direction of the air outlet 112, the auxiliary air duct 12 has a first port 123 located on the outer wall of the shell 1 and a second port 124 located on the inner wall of the main air duct 11, which can connect the outside of the shell assembly 10 and the main air duct 11, so that the cold air flow in the main air duct 11 can directly flow out of the air conditioner 100 through the multiple micropores 31 on the switch door 3, and can also flow into the auxiliary air duct 12 through the second port 124, and then flow out of the air conditioner 100 through the first port 123. While achieving a windless design, the air volume of the air conditioner 100 can be increased, the cooling effect of the air conditioner 100 can be improved, and the user experience can be improved.

[0072] In a specific example, see the attached Figure 1 and attached Figure 2 As shown, the angle C between the axis f of the micropore 31 and the axis g of the air outlet 112 is 20°, and both sides of the air outlet 112 in the width direction have auxiliary air ducts 12. The air volume of the air conditioner 100 in the pure air supply mode can reach 1561m 3 / h, the wind volume in no-wind mode can reach 955m 3 / h (1050rpm), which is much higher than the air volume of the air conditioner in the prior art in the windless mode. This is because the auxiliary air ducts 12 on both sides are not blocked by the microporous guide plates 31, and the resistance is smaller, and the air flow is smoother, resulting in a larger air volume. For example, the wind speed is measured in the range of X = 1m, height Z = 1.1m, and Y = 0m-3.2m in front of the air conditioner 100. The maximum wind speed is only 0.78m / s, which greatly reduces the wind speed in front of the air conditioner 100, realizes the windless design, and improves the user experience.

[0073] Reference below Figures 1 to 3 An air conditioner 100 according to a specific embodiment of the present invention is described. It should be understood that the following description is merely exemplary and is intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0074] Specifically, Figures 1 to 3 As shown, the air conditioner 100 includes: a housing assembly 10 of the air conditioner 100 , a heat exchanger 20 and a wind wheel 30 .

[0075] Further, the housing assembly 10 includes: a housing 1, a guide member 2 and a switch door 3. The housing 1 has a main air duct 11, an auxiliary air duct 12, and an air inlet 111 and an air outlet 112 connected to the main air duct 11. The air outlet 112 has auxiliary air ducts 12 on both sides of the width direction. Each auxiliary air duct 12 has a first port 123 located on the outer wall of the housing 1 and a second port 124 located on the inner wall of the main air duct 11. The second ports 124 of the two auxiliary air ducts 12 are arranged at intervals along the airflow direction of the main air duct 11. The inner wall of one side of the width direction of the main air duct 11 has a volute tongue portion 113. The first auxiliary air duct 121 is located on the same side of the main air duct 11 in the width direction as the volute tongue portion 113, and the second auxiliary air duct 122 is located on the opposite side of the main air duct 11 in the width direction as the volute tongue portion 113. The second port 124 of the first auxiliary air duct 121 is located downstream of the second port 124 of the second auxiliary air duct 122.

[0076] Furthermore, the guide member 2 is located at the air outlet 112 and is separated from both ends of the air outlet 112 in the width direction. In the process of the air flow flowing from the air inlet 111 to the air outlet 112, the setting of the guide member 2 can divert the air flow in the main air duct 11, so that the air flow is divided into two streams and blown out in different directions, so as to increase the air outlet area of ​​the air conditioner 100 and improve the cooling and heating effects of the air conditioner 100.

[0077] Furthermore, the switch door 3 can be movably arranged at the air outlet 112 and includes two switch doors 3, which are respectively located on both sides of the guide member 2 along the width direction of the air outlet 112, and are used to open or close the air outlet 112. Each switch door 3 is provided with a plurality of spaced micropores 31 to allow the airflow in the main air duct 11 to flow out of the air outlet 112. When the switch door 3 closes the air outlet 112, the auxiliary air duct 12 is used to allow the airflow in the main air duct 11 to flow out of the shell 1. When the switch door 3 opens the air outlet 112, the auxiliary air duct 12 is used to allow the airflow outside the shell 1 to enter the main air duct 11.

[0078] Furthermore, along the airflow flow direction of the main air duct 11, the axes f of the micropores 31 on the two switch doors 3 are inclined in directions away from each other, and the angle between the axis f of the micropore 31 and the axis g of the air outlet 112 is C, and satisfies: 18°≤C≤22°, which can prevent the air volume in front of the air conditioner 100 from being too concentrated, can greatly reduce the air outlet speed of the air conditioner 100 at the front, improve the windless design effect of the air conditioner 100, take into account the problem of children's cold wind protection, meet the user's demand for windless use, reduce the probability of users experiencing discomfort symptoms such as air-conditioning disease, improve user comfort, and can increase the air supply angle at the air outlet 112 to improve the cooling effect of the air conditioner 100. At the same time, it can also avoid the air outlet 112 from sucking the airflow at the first port 123.

[0079] Furthermore, guide plates 125 are provided at both ends of the first port 123 of the first sub-air duct 121 in the width direction. The guide plates 125 extend toward the first sub-air duct 121 and in the direction away from the air outlet 112. The width of the guide plates 125 is D and satisfies: D ≥ 30 mm, which can ensure the guiding effect of the guide plates 125, so that the airflow in the first sub-air duct 121 flows out from the first port 123 along the extension direction of the guide plates 125. The angle between the guide plate 125 and the width direction of the air outlet 112 is A, the second sub-air duct 122 extends in the direction away from the air outlet 112, and the angle between the line connecting the centers of the first port 123 and the second port 124 of the second sub-air duct 122 and the width direction of the air outlet 112 is B, and satisfies: A=B, 15°≤A≤25°, which can further prevent the airflow at the first port 123 of the first sub-air duct 121 and the second sub-air duct 122 from being sucked by the airflow at the air outlet 112, thereby ensuring the normal air outlet of the first sub-air duct 121, the second sub-air duct 122 and the air outlet 112.

[0080] Furthermore, the distance between the first port 123 and the end of the air outlet 112 close to each other is L1, and the distance between the first port 123 and the end of the air inlet 111 close to each other is L2, L1≥45mm, L2≥45mm, to ensure that the spacing between the first port 123 and the air outlet 112 and the air inlet 111 is appropriate, to ensure the normal air outlet and air induction of the auxiliary air duct 12, the normal air outlet of the air outlet 112 and the normal air inlet of the air inlet 111. The width of the auxiliary air duct 12 is L3, L3≥20mm, to ensure the normal air outlet of the auxiliary air duct 12, to avoid excessive pressure loss along the way due to obstacles in the auxiliary air duct 12, uneven inner wall of the auxiliary air duct 12 or too narrow first port 123, thereby affecting the normal air outlet in the auxiliary air duct 12.

[0081] In addition, air outlet grilles 23 are provided on both sides of the guide member 2 along the width direction of the air outlet 112. On the one hand, the air outlet grilles 23 can prevent hands or other foreign objects from reaching into the interior of the shell 1, thereby protecting the safety of the user and ensuring the normal operation of the air conditioner 100; on the other hand, the air outlet grilles 23 can prevent insects, mice, etc. from entering the shell assembly 10 of the air conditioner 100 and causing damage to the air conditioner 100, thereby ensuring the beautiful appearance of the shell assembly 10 and ensuring the normal operation of the air conditioner 100. At the same time, the setting of the air outlet grilles 23 can also disperse the airflow when the airflow passes through, thereby achieving a certain degree of windless design, making the blown airflow more comfortable.

[0082] In addition, the heat exchanger 20 and the wind wheel 30 are arranged in the main air duct 11. Along the flow direction of the air flow, the heat exchanger 20 is arranged upstream of the wind wheel 30. The wind wheel 30 can drive the air flow outside the air conditioner 100 to enter the main air duct 11 through the air inlet 111. The air flow in the main air duct 11 can exchange heat with the heat exchanger 20. The air flow after heat exchange can be blown into the room through the air outlet 112, thereby achieving the effect of adjusting the indoor temperature and meeting the user's usage needs.
