Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air conditioning technology, and specifically refers to a duct machine and an air conditioning device. Background Art

[0002] At present, traditional duct machines generally use a common engineering panel, and the air outlet does not have the ability to adjust the air direction, resulting in problems such as hot air being difficult to reach the ground, and poor comfort. A small number of models can be used with the original 3D panel, and the air outlet has the ability to adjust the air direction, but the installation is complex, affecting the indoor decoration style, and few users purchase it. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a duct machine and an air conditioning device that can enable the air outlet of the duct machine to have the ability to adjust the air direction, and the installation is simple and does not affect the indoor decoration style.

[0004] An embodiment of this application provides a duct machine, including: a housing, in which a main air duct and an auxiliary air duct that are separated from each other and arranged side by side in a first direction are provided, and the auxiliary air duct has an air inlet and an air outlet; and a wind guiding structure, which is arranged at the air outlet and is provided with an air outlet channel communicated with the air outlet, and is configured to be able to rotate relative to the housing to adjust the air outlet direction of the auxiliary air duct.

[0005] For the duct machine provided by the embodiment of this application, on the basis of the main air duct, an auxiliary air duct is added. Since a rotatable wind guiding structure is provided at the air outlet of the auxiliary air duct, the air outlet direction of the auxiliary air duct can be adjusted. The air flow output by the auxiliary air duct is located on one side of the air flow output by the main air duct, which can change the flow field on this side of the main air duct, thereby being able to affect the air flow direction of the main air duct and playing a role in adjusting the air outlet direction of the main air duct. Thus, the air outlet of the duct machine has the ability to adjust the air direction, and there is no need to install a complex 3D panel, which will not affect the indoor decoration style. In this way, by reasonably arranging the relative positions of the auxiliary air duct and the main air duct, the air outlet of the main air duct can bring a better user experience to users. For example: setting the auxiliary air duct above the main air duct can use the air flow of the auxiliary air duct to press down the air flow of the main air duct to improve the problem that hot air is difficult to reach the ground in the heating mode.

[0006] In addition, a wind deflector is provided at the air outlet to adjust the air outlet direction. However, only the part of the air flow close to the wind deflector can be effectively redirected, while the air flow far from the wind deflector cannot be effectively redirected and will disperse to a large extent. Compared with the above scheme of setting a wind deflector at the air outlet to adjust the air outlet direction, the wind guiding structure of this scheme is provided with an air outlet channel communicating with the air outlet. The air flow at the air outlet needs to be discharged through the air outlet channel. When the wind guiding structure rotates, the entire air outlet channel also rotates synchronously. Therefore, the air flow in the air outlet channel can also be redirected as a whole without dispersion, which is equivalent to playing a good sealing role. Therefore, the wind direction adjustment ability is better, which is beneficial to accurately control the air outlet direction.

[0007] Based on the above technical solutions, the present application can be further improved as follows.

[0048] The principles and features of the present application will be described below with reference to the accompanying drawings. The examples given are only for explaining the present application and are not intended to limit the scope of the present application.

[0049] An embodiment of the present application provides an air duct machine, which can be installed in a suspended manner and hidden in the ceiling. The air duct machine includes: a housing 1 and an air guiding structure 5, as Figure 1 、 Figure 2 and Figure 4 shown.

[0050] Among them, a main air duct 121 and an auxiliary air duct 122 which are separated from each other and arranged side by side in the first direction are provided in the housing 1, as Figure 2 shown. The auxiliary air duct 122 has an intake port 1224 and an outlet port 1225, as Figure 4 shown.

[0051] The air guiding structure 5 is arranged at the outlet port 1225 and is provided with an air outlet channel 56 (as Figure 16 shown) communicating with the outlet port 1225, and is configured to be able to rotate relative to the housing 1 to adjust the outlet direction of the auxiliary air duct 122.

[0052] The air duct machine provided by the embodiment of the present application is provided with an auxiliary air duct 122 on the basis of the main air duct 121. Since a rotatable air guiding structure 5 is provided at the air outlet of the auxiliary air duct 122, the air outlet direction of the auxiliary air duct 122 can be adjusted. The air flow output by the auxiliary air duct 122 is located on one side of the air flow output by the main air duct 121, which can change the flow field on this side of the main air duct 121, thereby affecting the air flow direction of the main air duct 121 and playing a role in adjusting the air outlet direction of the main air duct 121. Thus, the air outlet of the air duct machine has the ability to adjust the air direction, and there is no need to install a complex 3D panel, which will not affect the indoor decoration style. In this way, by reasonably arranging the relative positions of the auxiliary air duct 122 and the main air duct 121, the air outlet of the main air duct 121 can bring a better user experience to users. For example: by arranging the auxiliary air duct 122 above the main air duct 121, the air flow of the auxiliary air duct 122 can be used to press down the air flow of the main air duct 121 to improve the problem that the hot air is difficult to reach the ground in the heating mode.

[0053] In addition, setting a wind deflector at the air outlet 1225 can also adjust the air outlet direction. However, only the part of the air flow close to the wind deflector can be effectively deflected, while the air flow far from the wind deflector cannot be effectively deflected and will be dissipated to a large extent. Compared with the scheme of setting a wind deflector at the air outlet 1225 to adjust the air outlet direction, the air guiding structure 5 of this scheme is provided with an air outlet channel 56 communicated with the air outlet 1225. The air flow at the air outlet 1225 needs to be discharged through the air outlet channel 56. When the air guiding structure 5 rotates, the entire air outlet channel 56 also rotates synchronously. Therefore, the air flow in the air outlet channel 56 can also be deflected as a whole without dissipation, which is equivalent to playing a good sealing role. Therefore, the air direction adjustment ability is better, which is beneficial to accurately controlling the air outlet direction.

[0054] In some exemplary embodiments, a limiting shell 14 protrudes at the air outlet 1225. As Figure 2 and Figure 4 shown, at least part of the air guiding structure 5 is located in the limiting shell 14 and is rotatably matched with the inner wall surface of the limiting shell 14. This is beneficial to avoiding air leakage between the air guiding structure 5 and the limiting shell 14, so that the air flow output by the auxiliary air duct 122 is discharged through the air outlet channel 56 as much as possible, in order to accurately control the air outlet direction. Moreover, the limiting shell 14 can limit the air guiding structure 5, which is beneficial to improving the position stability and use reliability of the air guiding structure 5 during use.

[0055] In some exemplary embodiments, as Figure 16 and Figure 18As shown, the inner wall surface of the limit shell 14 includes a first wall surface 141 and a second wall surface 142 that are relatively spaced apart in the first direction. First arc surfaces 143 are provided at the upstream ends of both the first wall surface 141 and the second wall surface 142, and a second arc surface 57 is provided at the upstream end of the outer wall surface of the air guiding structure 5. The first arc surface 143 is adapted to the second arc surface 57 so that the air guiding structure 5 can rotate relative to the limit shell 14.

[0056] This is beneficial to increasing the contact area between the air guiding structure 5 and the limit shell 14, and is beneficial to improving the position stability and use reliability of the air guiding structure 5 during use.

[0057] In some exemplary embodiments, such as Figure 16 and Figure 18 As shown, a first limit surface 1411 is provided at the downstream end of the first wall surface 141, and a second limit surface 1421 is provided at the downstream end of the second wall surface 142. The air guiding structure 5 is arranged to be able to rotate between a first position and a second position. Based on the air guiding structure 5 rotating to the first position, as Figure 16 shown, the air guiding structure 5 is in abutting fit with the first limit surface 1411. Based on the air guiding structure 5 rotating to the second position, as Figure 18 shown, the air guiding structure 5 is in abutting fit with the second limit surface 1421.

[0058] Therefore, the first limit surface 1411 and the second limit surface 1421 can limit the rotation amplitude of the air guiding structure 5, facilitating the reliable positioning of the air guiding structure 5 in the first position or the second position.

[0059] In some exemplary embodiments, such as Figure 16 and Figure 18 shown, the second wall surface 142 is located between the first wall surface 141 and the main air duct 121. Therefore, the second wall surface 142 is relatively close to the main air duct 121, and the first wall surface 141 is relatively far from the main air duct 121. The inner wall surface of the air outlet channel 56 extends in a straight line direction parallel to the central axis of the air outlet channel 56. Therefore, the air outlet channel 56 is a straight channel with a constant cross-sectional area of flow, facilitating the output of high-speed air flow and avoiding the dissipation of air flow. The cross-sectional area of flow of the air outlet channel 56 is equal to the cross-sectional area of flow of the air outlet 1225.

[0060] Such as Figure 16 and Figure 18As shown, the first limiting surface 1411 extends along a straight line parallel to the central axis of the air outlet 1225. Along the air flow direction, the second limiting surface 1421 extends obliquely away from the first wall surface 141 in a straight line direction. Therefore, when the air guiding structure 5 rotates to the first position, the air outlet channel 56 is parallel to the first limiting surface 1411, so the air outlet direction of the auxiliary air duct 122 is parallel to the first limiting surface 1411. When the air guiding structure 5 rotates to the second position, the air outlet channel 56 is parallel to the second limiting surface 1421, and the air outlet direction of the auxiliary air duct 122 is parallel to the second limiting surface 1421.

[0061] In some exemplary embodiments, a fan chamber 11 and a heat exchange chamber 12 are provided in the housing 1, as Figure 4 shown. A main air duct 121 and an auxiliary air duct 122 are provided in the heat exchange chamber 12. The air duct machine further includes a fan 2 and a heat exchanger 3. The fan 2 is at least partially disposed in the fan chamber 11, and the air outlet end of the fan 2 is communicated with the heat exchange chamber 12, and is configured to supply air to the main air duct 121 and the auxiliary air duct 122. The heat exchanger 3 is at least partially disposed in the main air duct 121, and is configured to perform heat exchange with the air flow passing through the main air duct 121.

[0062] A middle partition 15 may be provided in the housing 1, as Figure 3 shown. The middle partition 15 divides the internal space of the housing 1 into a fan chamber 11 and a heat exchange chamber 12. The air outlet end of the fan 2 may pass through the middle partition 15 to communicate with the heat exchange chamber 12. The housing 1 is provided with an air inlet communicated with the fan chamber 11, and the air inlet is for indoor air to enter the fan chamber 11. The housing 1 is provided with an air outlet communicated with the main air duct 121, and the air outlet is for the air flow in the main air duct 121 to be discharged into the indoor space. The air inlet end of the main air duct 121 is directly communicated with the output end of the fan 2, and the air flow output by the fan 2 enters the main air duct 121 to exchange heat with the heat exchanger 3 and is then discharged into the indoor space through the air outlet. The housing 1 may be provided with an air outlet flange 16, and the air flows output from the air inlet 1224 and the air outlet are output into the indoor space through the air outlet flange 16.

[0063] In some exemplary embodiments, the air duct machine further includes a second driving member 62, as Figure 9 and Figure 10 shown. The second driving member 62 is connected to the air guiding structure 5 and is configured to drive the air guiding structure 5 to rotate relative to the housing 1, so as to facilitate automatically adjusting the air outlet direction of the auxiliary air duct 122 through a program.

[0064] In some exemplary embodiments, the fan 2 includes a plurality of volutes 21 arranged at intervals along the second direction, as Figure 3 , Figure 6 shown. A wind wheel is provided in each volute 21, so that the fan 2 can generate a large air volume. The fan chamber 11 and the heat exchange chamber 12 are arranged along the third direction. The third direction, the second direction and the first direction are perpendicular to each other in pairs.

[0065] The connection portion between the second driving member 62 and the air guide structure 5 is staggered with the plurality of volutes 21 in the third direction, such as Figure 3 This can avoid the connection between the second driving member 62 and the air guide structure 5 facing the air outlet end of the volute 21 to generate a large wind resistance, thereby helping to reduce wind resistance and increase air output.

[0066] In some exemplary embodiments, Figure 1 As shown, the first direction is the height direction of the housing 1, that is, the up-down direction. The second direction is the length direction of the housing 1, that is, the left-right direction. The third direction is the width direction of the housing 1, that is, the front-back direction. An auxiliary air duct 122 is provided on the upper side of the main air duct 121.

[0067] When an auxiliary air duct 122 is provided on the upper side of the main air duct 121, Figure 2 , Figure 4 and Figure 5 As shown in FIG. 1 , since the contact area between the airflow of the auxiliary air duct 122 and the heat exchanger 3 is small (or not in contact), the airflow temperature output from the auxiliary air duct 122 in the heating mode will be lower than the airflow temperature output from the main air duct 121. Therefore, the sinking effect of the low-temperature airflow output from the auxiliary air duct 122 can be used to press down the high-temperature airflow output from the main air duct 121, so that the hot air falls to the ground, as shown in FIG. Figure 20 As shown, the problem of hot air from the duct machine being difficult to land is improved.

[0068] In some exemplary embodiments, the rotation axis of the air guide structure 5 extends along the second direction, so the air guide structure 5 can rotate around its rotation axis toward or away from the main air duct 121 to effectively adjust the airflow direction of the main air duct 121.

[0069] In some exemplary embodiments, a duct assembly 13 is provided in the housing 1, such as Figure 1 The air duct assembly 13 includes an air duct partition plate 131, an air duct wall plate 132 and an air duct side plate 133. Figure 13 and Figure 14 The duct side plate 133 is connected to the duct partition plate 131 and the duct wall plate 132. The duct partition plate 131 and the duct wall plate 132 are arranged relatively spaced apart along the first direction, and together with the duct side plate 133, they enclose the auxiliary duct 122. The duct partition plate 131 separates the main duct 121 from the auxiliary duct 122.

[0070] The second driving member 62 is at least partially located outside the auxiliary air duct 122 and fixed to the air duct wall plate 132. Figure 3 and Figure 10 As shown, this can prevent the second driving member 62 from occupying the internal space of the main air duct 121 or the auxiliary air duct 122, which is beneficial to reducing wind resistance.

[0071] In some exemplary embodiments, the air guiding structure 5 includes a first baffle 51 and a second baffle 52 that are spaced apart from each other in a first direction. As Figure 10 shown, an air outlet channel 56 is defined between the first baffle 51 and the second baffle 52. The first baffle 51 and the second baffle 52 are provided with the above-mentioned second arc surface 57.

[0072] As Figure 10 shown, the air guiding structure 5 further includes a first partition 53 and a second partition 54 that are spaced in the air outlet channel 56. A rotating shaft 55 is connected between the first partition 53 and the second partition 54. A first engaging portion 551 is provided on the outer sidewall of the rotating shaft 55. An output shaft 621 of the second driving member 62 is provided with a second engaging portion 622. The output shaft 621 is perpendicular to the rotating shaft 55 and the first engaging portion 551 meshes with the second engaging portion 622. Wherein, the first engaging portion 551 can be, but is not limited to, a thread or a rack, and the second engaging portion 622 can be, but is not limited to, a tooth. The second engaging portion 622 and the output shaft 621 can be an integral structure or a split assembly structure (as Figure 12 shown).

[0073] When the first engaging portion 551 is a thread, as Figure 10 shown, the second driving member 62 can be, but is not limited to, a stepping motor. When the output shaft 621 of the second driving member 62 rotates, it can drive the rotating shaft 55 of the air guiding structure 5 to rotate, and then drive the air guiding structure 5 to rotate. When the first engaging portion 551 is a rack, the second driving member 62 can be, but is not limited to, a linear motor. When the output shaft 621 of the second driving member 62 moves linearly, it can drive the rotating shaft 55 of the air guiding structure 5 to rotate, and then drive the air guiding structure 5 to rotate.

[0074] Of course, the connection manner between the second driving member 62 and the air guiding structure 5 is not limited to the above manner, and other transmission structures can also be set to achieve indirect connection.

[0075] In some exemplary embodiments, the air duct machine further includes: a health module (not shown in the figure), which is provided at the air outlet 1225 and is configured to cause the auxiliary air duct 122 to release health factors outward, so as to facilitate the use of the high-speed air flow output by the auxiliary air duct 122 to release more health factors into the indoor space to improve the indoor air quality.

[0076] Wherein, the health module can be, but is not limited to, a plasma generator, a negative ion generator, etc. The health factors can include, but are not limited to: negative ions, plasma, free radicals, strongly oxidizing active substances, etc.

[0077] In some exemplary embodiments, the auxiliary air duct 122 is provided with a variable cross-section channel whose flow-through cross-sectional area gradually decreases along the air flow direction (i.e., the air flow direction from the air inlet 1224 to the air outlet 1225 of the auxiliary air duct 122), so that the flow-through cross-sectional area of the air inlet 1224 is larger than that of the air outlet 1225, as Figure 4 shown. According to the fluid continuity equation, the mass of the fluid passing through the two variable cross-sections per unit time is the same, so the fluid will be accelerated when passing through the contraction channel. According to Bernoulli's equation, the acceleration of the fluid will generate a pressure drop.

[0078] Since the auxiliary air duct 122 has a variable cross-section design such that the flow-through cross-sectional area of the air inlet 1224 is larger than that of the air outlet 1225, the auxiliary air duct 122 can output high-speed air flow, which is beneficial to increasing the air supply distance of the air duct machine, thereby being beneficial to improving the uniformity of the indoor temperature and improving the user experience.

[0079] Moreover, the air flow output by the auxiliary air duct 122 is located on one side of the air flow output by the main air duct 121, which can change the flow field on this side of the main air duct 121, and thus can affect the air flow direction of the main air duct 121, playing a role in adjusting the air outlet direction of the main air duct 121.

[0080] In some exemplary embodiments, the auxiliary air duct 122 includes an air inlet section 1221 and an acceleration section 1222, as Figure 4 shown. The acceleration section 1222 is located on the downstream side of the air inlet section 1221 and is in communication with the air inlet section 1221. The variable cross-section channel is provided in the acceleration section 1222. Among them, the acceleration section 1222 can be entirely set as a variable cross-section channel or partially set as a variable cross-section channel.

[0081] As Figure 4 shown, the air inlet section 1221 is arranged offset from the output end of the fan 2 in the first direction, and the air inlet 1224 is provided on the wall surface of the air inlet section 1221 close to the main air duct 121. In this way, the air inlet section 1221 does not block the air outlet end of the fan 2, which is beneficial to reducing the wind resistance, and the air flow output by the output end of the fan 2 can be divided into two paths, one path directly enters the main air duct 121, and the other path enters the auxiliary air duct 122 through the air inlet 1224.

[0082] In some exemplary embodiments, the auxiliary air duct 122 further includes a turning section 1223, as Figure 4 shown. The turning section 1223 is located on the downstream side of the acceleration section 1222 and is in communication with the acceleration section 1222, and the turning section 1223 extends obliquely in the direction close to the main air duct 121 along the air flow direction, and the air outlet 1225 is provided at the end of the turning section 1223.

[0083] This facilitates reducing the distance between the air outlet 1225 of the auxiliary air duct 122 and the air outlet of the main air duct 121, which is beneficial to enhancing the influence of the air flow output by the auxiliary air duct 122 on the air flow output by the main air duct 121. Moreover, this also facilitates introducing the air flow output by the auxiliary air duct 122 into the original air outlet flange 16 without increasing the size of the air outlet flange 16.

[0084] In some exemplary embodiments, as Figure 4 shown, along the air flow direction, the accelerating section 1222 extends obliquely away from the main air duct 121 along the wall surface close to the main air duct 121, so that the thickness of the accelerating section 1222 in the first direction gradually decreases, which serves to reduce the flow cross-sectional area of the accelerating section 1222 and thus increase the air flow velocity. And the wall surface of the accelerating section 1222 away from the main air duct 121 can extend linearly in the horizontal direction, with a regular structure and being convenient for installation.

[0085] In some exemplary embodiments, as Figure 3 shown, along the air flow direction, the length of the accelerating section 1222 in the second direction gradually increases, where the second direction is perpendicular to the first direction and perpendicular to the air flow direction. In other words, along the air flow direction, the thickness of the accelerating section 1222 gradually decreases but the length gradually increases, and overall the flow cross-sectional area of the accelerating section 1222 still gradually decreases. This is beneficial to reducing wind resistance and avoiding too rapid a decrease in air flow pressure to ensure the air flow rate and air flow velocity output by the auxiliary air duct 122.

[0086] In some exemplary embodiments, as Figure 3 、 Figure 6 shown, the fan 2 includes a plurality of volutes 21 arranged at intervals in the second direction. A wind wheel is provided in each volute 21, so that the fan 2 can generate a relatively large air volume.

[0087] As Figure 3 shown, the air intake section 1221 includes a plurality of sub-air intake sections 1226 arranged at intervals in the second direction. The plurality of sub-air intake sections 1226 correspond to the plurality of volutes 21 one by one. The air inlet 1224 includes a plurality of sub-air inlets 1228 arranged at intervals in the second direction, as Figure 7 and Figure 11 shown. The plurality of sub-air inlets 1228 are arranged corresponding to the plurality of sub-air intake sections 1226 one by one. In this way, the air flow output by each volute 21 can enter the corresponding sub-air intake section 1226 through the respective corresponding sub-air inlet 1228, which is beneficial to reducing air flow loss and beneficial to increasing the air flow rate entering the auxiliary air duct 122.

[0088] As Figure 3As shown, the acceleration section 1222 includes a plurality of sub-acceleration sections 1227 arranged at intervals in the second direction, and the plurality of sub-acceleration sections 1227 communicate with the plurality of sub-intake sections 1226 in a one-to-one correspondence. Along the air flow direction, the thickness of each sub-acceleration section 1227 in the first direction gradually decreases, the width in the second direction gradually increases, and the flow cross-sectional area gradually decreases. In this way, the air flow in each sub-acceleration section 1227 can be effectively accelerated to ensure that the air flow finally output by the auxiliary air duct 122 has a relatively high speed.

[0089] Among them, the sizes and shapes of the plurality of sub-acceleration sections 1227 can be exactly the same, can be completely different, or can be partially different, and can be specifically adjusted according to the distribution form of the plurality of volutes 21. For example: as Figure 3 shown, when the distance between two adjacent volutes 21 is relatively large, the inclination degree of the adjacent walls of the corresponding two sub-acceleration sections 1227 can be relatively large; when the distance between two adjacent volutes 21 is relatively small, the inclination degree of the adjacent walls of the corresponding two sub-acceleration sections 1227 can be relatively small.

[0090] In some exemplary embodiments, as Figure 3 shown, the number of the turning sections 1223 is one, and the turning section 1223 is connected to the plurality of sub-acceleration sections 1227. Therefore, the air flows output by the plurality of sub-acceleration sections 1227 converge in the turning section 1223 and are then output through the air outlet 1225, which is beneficial to improving the uniformity of the air flow output by the auxiliary air duct 122.

[0091] In some exemplary embodiments, the blower 2 includes a volute 21, and a diffuser plate 211 is provided at the air outlet end of the volute 21. As Figure 5 shown, the diffuser plate 211 is located on the opposite side of the volute tongue. The air duct machine further includes: an intake valve 4, which is provided at the intake port 1224. As Figure 4 and Figure 5 shown, it is arranged to control the opening and closing of the intake port 1224. Based on the intake valve 4 being in the position of closing the intake port 1224, the intake valve 4 is flush with the diffuser plate 211. As Figure 5 shown. In this way, when the auxiliary air duct 122 is not needed, the auxiliary air duct 122 can be closed, and the auxiliary air duct 122 and the intake valve 4 will not generate resistance to the air flow in the main air duct 121.

[0092] When the intake port 1224 includes a plurality of sub-intake ports 1228, the number of the intake valves 4 can be equal to the number of the sub-intake ports 1228 and in one-to-one correspondence, and the plurality of intake valves 4 can be linked and coordinated (for example, form an integral structure, or be connected through a linkage structure) to facilitate being driven by a first driving member 61. Alternatively, the intake valve 4 can also be one, which can simultaneously control the opening and closing of all the sub-intake ports 1228. As Figure 7 andFigure 11 as shown

[0093] In some exemplary embodiments, the air duct machine further includes: an intake valve 4 (as shown in Figure 4 and Figure 5 ) and a first driving member 61 (as shown in Figure 3 , Figure 7 and Figure 9 ). The intake valve 4 is disposed at the air intake 1224 and is configured to control the opening / closing and the opening degree of the air intake 1224. The first driving member 61 is connected to the intake valve 4 and is configured to drive the intake valve 4 to move relative to the housing 1.

[0094] In this way, when the auxiliary air duct 122 is not needed, the auxiliary air duct 122 can be closed. Moreover, by controlling the opening degree of the air intake 1224, the flow rate of the air flowing into the auxiliary air duct 122 can be controlled, so as to adjust the wind speed and the flow rate of the air outlet 1225 of the auxiliary air duct 122, and the air supply distance of the auxiliary air duct 122 can also be adjusted, and the influence on the air flow in the main air duct 121 can also be adjusted.

[0095] In some exemplary embodiments, a rotating connection portion is provided at one end of the intake valve 4 away from the blower 2. The rotating connection portion is connected to the first driving member 61 and is configured to drive the intake valve 4 to rotate relative to the housing 1 under the drive of the first driving member 61. The first driving member 61 can be, but is not limited to, a stepping motor. The rotating connection portion can be, but is not limited to, a rotating shaft 55 or a shaft hole. The first driving member 61 can be fixed to the air duct side plate 133, as shown in Figure 11 , and is located on one side where the input / output pipes of the heat exchanger 3 are located.

[0096] In this way, when the intake valve 4 is opened, it can guide the air flow, facilitating the air flow to enter the auxiliary air duct 122 along the intake valve 4. Moreover, by adjusting the opening angle of the intake valve 4 (as shown in Figure 8 ), the function of adjusting the opening degree of the air intake 1224 can be achieved, and further the air flow rate entering the auxiliary air duct 122 can be adjusted.

[0097] In some exemplary embodiments, as shown in Figure 3 , Figure 7 and Figure 9 , at least a part of the first driving member 61 is located outside the auxiliary air duct 122, which can prevent the first driving member 61 from blocking the air flow in the auxiliary air duct 122 and is beneficial to reducing the wind resistance. And the first driving member 61 is located on one side where the input / output pipes of the heat exchanger 3 are located, as shown in Figure 3As shown, it is convenient for the first driving member 61 to be routed. In addition, the input and output pipes of the heat exchanger 3 are usually staggered with the air outlet flange 16 of the air duct machine, so the first driving member 61 is located on the side where the input and output pipes of the heat exchanger 3 are located, and it can also avoid the first driving member 61 blocking the air flow entering the air outlet flange 16, which is conducive to reducing wind resistance. It can be that the first driving member 61 and the auxiliary air duct 122 are arranged along the second direction and are located on the side where the input and output pipes of the heat exchanger 3 are located.

[0098] In some exemplary embodiments, Figure 4 and Figure 5 As shown, the heat exchanger 3 is inserted into the auxiliary air duct 122 at an end portion close to the auxiliary air duct 122 to perform heat exchange with the airflow flowing through the auxiliary air duct 122 .

[0099] In this way, the airflow flowing through the auxiliary air duct 122 can also exchange heat with the heat exchanger 3, which is beneficial to reduce the temperature difference between the airflow output by the auxiliary air duct 122 and the airflow output by the main air duct 121, reduce the temperature difference distribution of the airflow output by the duct machine, and help improve the air outlet comfort of the duct machine.

[0100] Of course, the heat exchanger 3 may also be completely located in the main air duct 121 without performing heat exchange with the airflow of the auxiliary air duct 122 .

[0101] In some exemplary embodiments, a wall surface of the auxiliary air duct 122 close to the main air duct 121 is provided with a plug hole 1311 for the end of the heat exchanger 3 to pass through, such as Figure 7 , Figure 13 and Figure 14 As shown, the plug hole 1311 can extend into the main air duct 121 to form a convex edge, such as Figure 13 A first sealing member 171 is provided between the two ends of the heat exchanger 3 in the thickness direction and the hole wall of the insertion hole 1311, as shown in FIG. Figure 7 and Figure 13 As shown, a second sealing member 172 is provided between the heat exchanger 3 and the wall of the auxiliary air duct 122 away from the main air duct 121. Figure 7 and Figure 13 This is helpful to avoid air flow between the auxiliary air duct 122 and the main air duct 121, and is also helpful to improve the position stability of the heat exchanger 3.

[0102] The first sealing member 171 may be, but not limited to, a sponge. The second sealing member 172 may be, but not limited to, a sponge. The heat exchanger 3 may be, but not limited to, a finned heat exchanger 3 , and part of the fins of the heat exchanger 3 are embedded in the auxiliary air duct 122 .

[0103] In some exemplary embodiments, the ratio of the flow cross-sectional area of the air inlet 1224 to that of the air outlet 1225 is 4:1. Through testing, the air outlet speed can be increased by approximately 300%. Of course, the ratio of the flow cross-sectional area of the air inlet 1224 to that of the air outlet 1225 is not limited to this ratio and can also be other ratios.

[0104] In some exemplary embodiments, the first direction is the height direction of the housing 1. The auxiliary air duct 122 is located above the main air duct 121. The air guiding structure 5 is configured to rotate between a first position and a second position. Based on the air guiding structure 5 being in the first position, the air outlet passage 56 outputs air horizontally. Based on the air guiding structure 5 being in the second position, the air outlet passage 56 outputs air obliquely downward. In the cooling mode, the air supply mode, when the auxiliary air duct 122 is in the closed state, or when the whole machine is in the shutdown state, the air guiding structure 5 can be in the first position. In the heating mode, the air guiding structure 5 can be in the second position.

[0105] Moreover, in the cooling mode, when the air guiding structure 5 is in the first position, as Figure 15 and Figure 19 shown, the auxiliary air duct 122 outputs a high-speed air flow horizontally, which has a relatively large air supply distance, and the high-speed air flow generates a negative pressure effect above the main air duct 121, enabling the upper air flow output by the main air duct 121 to also obtain a farther air supply distance (increasing L). In this way, the overall air duct machine can obtain a farther air supply distance, and the cold air landing range can cover a larger range, realizing air curtain type air supply. By adjusting the opening degree of the air inlet 1224, the air flow rate and air flow speed of the auxiliary air duct 122 can be changed, thereby obtaining different air supply distances. By changing the air outlet direction of the air guiding structure 5, different air supply distances can also be obtained.

[0106] In the heating mode, when the air guiding structure 5 is in the second position, as Figure 17 and Figure 20 shown, the auxiliary air duct 122 outputs a high-speed air flow downward, forming an air curtain to restrain the floating hot air output by the main air duct 121 below, so that the hot air adheres to the ground, achieving the effect of warm foot air supply. By adjusting the opening degree of the air inlet 1224, the air flow rate and air flow speed of the auxiliary air duct 122 can be changed, thereby obtaining different air supply distances. By changing the air outlet direction of the air guiding structure 5, different air supply distances can also be obtained.
