[0002] Air conditioners are widely used for regulating the temperature of indoor environments. When an existing air conditioner is in operation, it generally blows air outward through the lower air outlet of its main air duct. The lower air outlet is located at the bottom of the air conditioner housing and blows air directly with a relatively large airflow intensity, resulting in poor comfort in the direct blowing area of ​​the lower air outlet. Based on this, some air conditioners are provided with a dispersing structure that can disperse the air. However, the dispersing structure and its air duct are prone to dust accumulation.

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0037] This embodiment provides an air conditioner indoor unit, such as Figure 1-Figure 4 As shown, it includes a shell 10, the front end plate of the shell 10 is provided with a first wind dispersion structure 221, a main air duct 110 and a wind dispersion duct 300 are provided in the shell 10, and the wind dispersion duct 300 is connected between the first wind dispersion structure 221 and the main air duct 110; the front side of the front end plate is slidably connected with a front baffle plate 400 along the up and down direction, and the front baffle plate 400 has an avoidance position avoiding the first wind dispersion structure 221 and a covering position completely covering the first wind dispersion structure 221; the shell 10 is provided with an air guide plate 500 for closing or opening the lower air outlet 120 of the main air duct 110, wherein, along the up and down direction of the shell 10, the lower air outlet 120 is located at the lower side of the first wind dispersion structure 221.

[0038] This embodiment also provides an air conditioner, including an air conditioner outdoor unit and the above-mentioned air conditioner indoor unit, and the air conditioner indoor unit and the air conditioner outdoor unit are connected through a refrigerant pipe to form a refrigerant circulation system.

[0039] The present embodiment provides an air conditioner indoor unit and an air conditioner, wherein the air conditioner indoor unit includes a shell 10 with an air duct formed inside and serving as a mounting base, a main air duct 110 and a scattered air duct 300 for conveying air to the outside, a first scattered air structure 221 located at the front end and used to disperse the airflow passing through, a front baffle 400 for adjusting the air flow rate of the first scattered air structure 221, and an air guide plate 500 for adjusting the air flow rate and air outlet direction of the main air duct 110; wherein the air conditioner includes an air conditioner outdoor unit for heat exchange with the outdoor environment and the above-mentioned air conditioner indoor unit for adjusting the temperature of the indoor environment.

[0040] When the air conditioner is used, the air guide plate 500 and the front baffle plate 400 can be adjusted as needed to make the air conditioner indoor unit enter different air outlet modes:

[0041] When the user needs to quickly adjust the indoor temperature, the air guide plate 500 can be opened to put the air conditioner into the quick adjustment mode. At this time, the airflow blown out of the main air duct 110 is almost entirely blown directly outward through the lower air outlet 120 in the open state, thereby achieving rapid adjustment of the indoor ambient temperature; at the same time, the angle between the air guide plate 500 and the lower air outlet 120 can be adjusted, so as to adjust the guiding direction of the air flow of the air guide plate 500 and the air outlet direction of the indoor unit of the air conditioner. In this rapid adjustment mode, the front baffle 400, which is in a continuously closed state, can be located in a covering position where it can completely cover the first wind dispersion structure 221 to cut off the connection between the indoor environment and the wind dispersion duct 300 through the first wind dispersion structure 221, thereby reducing the indoor airflow entering the wind dispersion duct 300 and contacting the cold airflow of the main air duct 110 to form condensed water, causing the lower air outlet 120 to blow liquid outward, and at the same time, it can also reduce the air volume loss caused by the airflow of the main air duct 110 flowing into the wind dispersion duct 300; or, the front baffle 400 can also be located to only block a portion of the first wind dispersion structure 221 or completely avoid the first wind dispersion structure When the first wind dispersing structure 221 is in the avoidance position, and the avoidance position is located at the lower side of the first wind dispersing structure 221, the front baffle plate 400 extending downward from the front end plate can cooperate with the wind guide plate 500 to guide the upper and lower sides of the airflow blown out of the lower air outlet 120, thereby improving the adjustability of the air outlet direction of the air conditioner indoor unit, and when the first wind dispersing structure 221 and the lower air outlet 120 are opened at the same time, due to the large resistance of the wind dispersing duct 300 and the first wind dispersing structure 221, the airflow of the main air duct 110 is mainly blown out through the lower air outlet 120 to ensure the air outlet flow of the air conditioner indoor unit, and correspondingly ensure the rapid adjustment of the indoor ambient temperature by the air conditioner.

[0042] When the user needs a more relaxed airflow blown out from the indoor unit of the air conditioner, the user can close the air guide plate 500 to close the lower air outlet 120, and at the same time slide the front baffle 400 to an avoidance position avoiding the first wind dispersion structure 221, and the air conditioner enters the wind dispersion mode. Since the lower air outlet 120 is closed by the air guide plate 500, the airflow in the main air duct 110 can flow into the wind dispersion duct 300 through the connecting port 310 between the wind dispersion duct 300 and the main air duct 110, and then be blown forward after being dispersed by the first wind dispersion structure 221. The wind speed of the blown airflow is relatively small, thereby improving the user's experience.

[0043] In the indoor unit of the air conditioner provided in the present embodiment, the air guide plate 500 and the front baffle plate 400 can be adjusted to make the air conditioner enter a quick adjustment mode with a larger flow rate and a faster temperature adjustment speed or a diffuse wind mode with a more relaxed air flow. Among them, in the quick adjustment mode, the angle between the air guide plate 500 and the lower air outlet 120 can be adjusted to adjust the air flow direction of the lower air outlet 120. At the same time, the front baffle plate 400 can be adjusted to be in the covering position to reduce the liquid blowing from the blowing outlet, increase the air volume of the lower air outlet 120, and ensure the air conditioner's rapid temperature adjustment of the indoor environment. The front baffle plate 400 can also be adjusted to be in the avoidance position extending downwardly from the front end plate. On the basis of ensuring the air volume of the lower air outlet 120, the front baffle plate 400 and the air guide plate 500 can jointly guide the air flow of the lower air outlet 120 at the upper and lower positions of the lower air outlet 120 for a better effect. In summary, the optional modes of the air conditioner are rich and varied, and in each mode, the front baffle 400 and the air guide plate 500 cooperate with each other to have a high degree of adjustability in the air flow direction, which correspondingly improves the functionality of the air conditioner indoor unit and the air conditioner, and improves the convenience and comfort of users.

[0044] When the air conditioner is not in use, the covering area of ​​the front baffle 400 is larger than the area of ​​the first wind dispersion structure 221. The front baffle 400 can be adjusted to slide to a covering position that completely covers the first wind dispersion structure 221, and the air guide plate 500 is adjusted to move to a position that closes the lower air outlet 120, thereby reducing the occurrence of pollution and blockage caused by external dust entering the wind dispersion duct 300 and the main air duct 110 through the first wind dispersion structure 221 and the lower air outlet 120 and depositing therein. At the same time, the front baffle 400 blocks the front side of the first wind dispersion structure 221, which can simultaneously reduce the deposition and blockage of the first wind dispersion structure 221 caused by dust, thereby ensuring the normal operation of the first wind dispersion structure 221, the air conditioner indoor unit and the air conditioner, and reducing the occurrence of secondary pollution to the indoor environment caused by the dust deposited in the first wind dispersion structure 221, the wind dispersion duct 300 and the main air duct 110 when the air conditioner is turned on.

[0045] Among them, the front baffle plate 400 is slidably connected to the front side of the front end plate along the up and down directions. In addition to the above-mentioned cooperation with the air guide plate 500 to guide the airflow blown out of the lower air outlet 120, and the first wind dispersion structure 221 and the wind dispersion duct 300 have the functions of blocking water, dust and blocking, the front baffle plate 400 can also be disassembled and maintained externally, and the disassembly and assembly are convenient. The setting and sliding of the front baffle plate 400 do not occupy the internal space of the shell 10 and the space outside the shell 10, thereby ensuring the arrangement of the wind dispersion duct 300 and the main air duct 110 inside the shell 10 and the arrangement of other items outside the shell 10, and correspondingly reducing the overall volume of the air conditioner indoor unit and the space it occupies.

[0046] Optionally, in this embodiment, one of the rear side wall of the front baffle 400 and the front side wall of the front end plate is provided with a slide groove 223 extending in the up-down direction, and the other is provided with a sliding joint slidably engaged in the slide groove 223; the rear side wall of the front baffle 400 is provided with a rack 410 extending in the up-down direction, and the housing 10 is provided with a first rotating driving member, and the driving end of the first rotating driving member is provided with a gear 11, and the gear 11 is meshed with the rack 410. When it is necessary to adjust the up-down position of the front baffle 400, the first rotating driving member can be started, and the first rotating driving member drives the gear 11 to rotate in the first direction, and the front baffle 400 slides upward under the sliding engagement between the sliding joint and the slide groove 223 and the meshing driving action of the gear 11 and the rack 410; or, the first rotating driving member drives the gear 11 to rotate in a second direction opposite to the first direction, and the front baffle 400 slides downward accordingly.

[0047] Preferably, there can be two slide grooves 223, such as Figure 5 and Figure 7 As shown, the two slide grooves 223 are respectively located at the left and right end areas of the front end plate, and there are two sliding joints, which are slidably connected to the two slide grooves 223 one by one, thereby limiting the positions of the left and right ends of the front baffle 400 to improve the stability of the front baffle 400 slidingly connected to the front end plate; similarly, as Fig.13 As shown, there can also be two racks 410, which are respectively located at the left and right end areas of the front baffle 400, and there are two corresponding gears 11, which are meshed with the two racks 410 one by one, thereby driving the left and right ends of the front baffle 400 to rise and fall, so as to improve the stability of the front baffle 400 sliding up and down relative to the front end plate.

[0048] Of course, in some other embodiments, a telescopic driving component, such as a telescopic cylinder, a push rod motor, etc., may also be provided in the shell 10, and the driving end of the telescopic driving component is connected to the front baffle 400 to drive its lifting movement.

[0049] Specifically, the air guide plate 500 is hinged to the rear area of ​​the lower air outlet 120, and a second rotating driving member can be provided on the housing 10, and a driving end of the second rotating driving member is connected to the air guide plate 500, so as to drive the air guide plate 500 to rotate relative to the lower air outlet 120. Specifically, the first rotating driving member and the second rotating driving member can be motors.

[0050] In this embodiment, Figure 1-Figure 12 As shown, the front end plate includes an upper closed area 210 and a lower wind dispersion area 220 from top to bottom, and the first wind dispersion structure 221 is located in the lower wind dispersion area 220. The upper area of ​​the front end plate is a closed area that cannot be ventilated, and the lower area is provided with a first wind dispersion structure 221 that can be ventilated. The first wind dispersion structure 221 and the wind dispersion duct 300 therein are close to the main wind duct 110 and away from the air inlet at the top of the shell 10. The wind dispersion duct 300 has a higher connectivity with the main wind duct 110 and a smaller flow resistance, which can ensure the air volume and temperature regulation effect of the wind dispersion mode. At the same time, it can effectively reduce the occurrence of the situation where the air outlet of the first wind dispersion structure 221 is easily backflowed upward to the air inlet due to the small distance between the first wind dispersion structure 221 and the air inlet at the top of the shell 10, which affects the temperature regulation effect of the air conditioner.

[0051] In this embodiment, Figure 1 and Figure 2 As shown, the air guide plate 500 is provided with a plurality of dispersedly arranged second wind dispersing structures 510. When the air guide plate 500 is opened and forms a certain angle with the lower air outlet 120, the setting of the second wind dispersing structure 510 has no effect on the smoothness of the guide surface of the air guide plate 500. Based on the large wind resistance of the second wind dispersing structure 510, the airflow blown out through the lower air outlet 120 flows outward through the guide surface first, thereby ensuring the guidance of the air outlet of the lower air outlet 120 when the air guide plate 500 is opened, so that the indoor unit of the air conditioner has normal direct airflow; when the air guide plate 500 is closed and the lower air outlet 120 is sealed, the airflow from the main air duct 110 to the lower air outlet 120 can be blown outward through the second wind dispersing structure 510, and the second wind dispersing structure 510 on the air guide plate 500 can disperse the airflow passing through, so that the indoor unit of the air conditioner has downward and forward downward wind dispersing airflow, correspondingly improving the functional diversity of the air conditioner. Among them, since the lower air outlet 120 is located at the bottom of the shell 10, when the air conditioner is not in use, the air guide plate 500 that closes the lower air outlet 120 is also located at the bottom of the shell 10. The probability of dust being deposited on the air guide plate 500 and the second wind dissipation structure 510 is small, and the cleanliness and smoothness of the second wind dissipation structure 510 can be ensured, thereby ensuring its wind dissipation function.

[0052] When the air guide plate 500 is provided with the second air dispersing structure 510, the air dispersing mode includes a downward air dispersing mode, and the rapid adjustment mode includes a cooling air guiding mode.

[0053] Among them, in the downward scattered wind mode, Figure 1 and Figure 2 As shown, the front baffle 400 is in the covering position, and the air guide plate 500 closes the lower air outlet 120. When the air conditioner is running, the airflow in the main air duct 110 can be blown out through the second wind dispersion structure 510 on the air guide plate 500 and the blowing process is dispersed, so that the indoor unit of the air conditioner has downward and forward dispersed air.

[0054] In cooling air flow mode, Figure 3 and Figure 4 As shown, the front baffle 400 is in the covering position, and the air guide plate 500 opens the lower air outlet 120 and extends forward. The airflow of the main air duct 110 is blown out through the lower air outlet 120. Under the guiding effect of the air guide plate 500, the cold airflow blown out through the lower air outlet 120 can be blown forward for a longer distance, thereby realizing rapid cooling adjustment of the indoor environment.

[0055] The front baffle 400 can slide up and down relative to the area where the first wind dispersing structure 221 is located. When the front baffle 400 slides upward to only block the upper edge area of ​​the first wind dispersing structure 221 or completely avoids the first wind dispersing structure 221 without blocking it, the front baffle 400 is located in the upper avoidance position; when the front baffle 400 slides to completely cover the first wind dispersing structure 221, the front baffle 400 is located in the covering position; when the front baffle 400 slides downward to only block the lower edge area of ​​the first wind dispersing structure 221 or completely avoids the first wind dispersing structure 221 without blocking it, the front baffle 400 is located in the lower avoidance position. In the present application, the up and down sliding stroke of the front baffle 400 includes at least one of the upper avoidance position and the lower avoidance position, and also includes the covering position, so as to avoid and completely cover the first wind dispersing structure 221.

[0056] Among them, Figure 1 and Figure 2 As shown, the covering position can be the highest position of the sliding stroke of the front baffle 400, the lower wind dispersing area 220 is concave relative to the upper closed area 210 to form a receiving groove 222, and the front baffle 400 is embedded in the receiving groove 222 when it is in the covering position. The sliding stroke of the front baffle 400 includes the covering position and the lower avoidance position. The shape and size of the front baffle 400 match the receiving groove 222. When the front baffle 400 slides upward to the highest position, it is located in the covering position and completely covers the first wind dispersing structure 221. At the same time, the front baffle 400 is matched and embedded in the receiving groove 222, which can not only improve the air tightness of the front baffle 400 covering the first wind dispersing structure 221 to reduce the air leakage of the first wind dispersing structure 221, but also make the front baffle 400 and the front end plate approximately combined into a plate body with a flat front end surface, thereby improving the overall structural neatness and appearance of the air conditioner when the air conditioner is in the off state.

[0057] Of course, in some other embodiments, the covering position may also be the lowest position of the sliding stroke of the front baffle 400, and the sliding stroke of the front baffle 400 includes an upper avoidance position and a covering position; or, the sliding stroke of the front baffle 400 may include an upper avoidance position, a covering position and a lower avoidance position, and the front baffle 400 can be adjusted to slide to the upper avoidance position or the lower avoidance position according to needs to avoid the first wind dissipation structure 221.

[0058] When the sliding stroke of the front baffle 400 includes the upper avoidance position, in this embodiment, the top of the housing 10 is provided with an air inlet, such as Fig.11 and Fig.12 As shown, along the up-down direction of the housing 10, the extension length of the lower wind dispersing area 220 is less than or equal to the extension length of the upper closed area 210. The upper closed area 210 with a larger up-down extension length can further increase the distance between the first wind dispersing structure 221 and the air inlet at the top of the housing 10, thereby further reducing the upward reflux of the air outflow of the first wind dispersing structure 221 to the air inlet, resulting in a poor temperature regulation effect of the air conditioner. In addition, the area where the upper closed area 210 is located serves as a sliding area of ​​the front baffle 400. The front baffle 400 can slide upward to the upper avoidance position. All effective wind dispersion areas of the first wind dispersion structure 221 are not blocked by the front baffle 400, and air can be discharged and dispersed, thereby ensuring the wind dispersion effect of the first wind dispersion structure 221 and the air-conditioning indoor unit in the wind dispersion mode; at the same time, the front baffle 400 does not extend upward from the upper closed area 210, and accordingly will not block the front side of the top air inlet, which can ensure smooth air intake of the air inlet and the air intake volume of the air-conditioning indoor unit, thereby ensuring the temperature regulation efficiency of the air-conditioning indoor unit.

[0059] Among them, when the air guide plate 500 is provided with a second wind dispersion structure 510, and the avoidance position includes a lower avoidance position located at the lower side of the first wind dispersion structure 221, the wind dispersion mode also includes a first full wind dispersion mode, the rapid adjustment mode also includes a heating air guide mode, and the air conditioner indoor unit also has a mixed air mode.

[0060] Specifically, in the mixed air mode, Figure 5 and Figure 6As shown, the wind guide plate 500 opens the lower air outlet 120 and extends forward, the front baffle 400 is located in the lower avoidance position, and the front baffle 400 and the wind guide plate 500 overlap each other; the wind guide plate 500 is rotated downward to open a certain angle, and the front baffle 400 slides downward to open, until the bottom end of the front baffle 400 overlaps the upper guide surface of the wind guide plate 500, or the front end of the wind guide plate 500 overlaps the rear side wall of the front baffle 400, or the front end of the wind guide plate 500 overlaps the bottom end of the front baffle 400, then the first wind dissipation structure 221 located at the front end plate is in an open state, and the front baffle 400 and the wind guide plate 500 jointly block the lower air flow. The air outlet 120 and the left and right ends of the two form an end air outlet 610; when the air conditioner is running, since the lower air outlet 120 of the main air duct 110 is blocked by the front baffle 400 and the wind guide plate 500 and there is a large wind resistance, a part of the airflow of the main air duct 110 flows into the wind dispersion duct 300 through the connecting port 310, and then is dispersed and blown forward through the first wind dispersion structure 221; the other part of the airflow is blown out through the lower air outlet 120 and is divided into two airflows, one of which is dispersed and blown downward through the second wind dispersion structure 510 of the wind guide plate 500, and the other airflow is blown to the left and right through the left and right end air outlets 610 as shown by the dotted arrows. The mixed wind mode can make the air conditioner indoor unit have the forward air dispersion outlet through the first air dispersion structure 221, the downward air dispersion outlet through the second air dispersion structure 510 and the rapid air discharge to the left and right through the two end air outlets 610, so that the area in front of the air conditioner indoor unit corresponding to the first air dispersion structure 221 and the area below the air conditioner indoor unit corresponding to the second air dispersion structure 510 are breeze feeling areas blown by the wind, the left and right side areas corresponding to the two end air outlets 610 of the air conditioner indoor unit are direct blowing wind feeling areas with relatively strong wind force, and the front lower area of ​​the air conditioner indoor unit corresponding to the front baffle 400 is approximately a windless feeling area, and the user can be located in the breeze feeling area, the direct blowing wind feeling area or the windless feeling area as needed, with many choices and high usage experience. At the same time, the rapid air discharge of the end air outlets 610 can ensure the rapid temperature adjustment of the indoor environment by the air conditioner, thereby greatly improving the functionality of the air conditioner indoor unit and the air conditioner.

[0061] In the heating and air conduction mode, Figure 7 and Figure 8 As shown, the front baffle 400 is located in the lower avoidance position, and the air guide plate 500 opens the lower air outlet 120 and extends downward; the airflow of the main air duct 110 is mainly blown out through the lower air outlet 120, and the air guide plate 500 is hinged at the rear edge of the lower air outlet 120, and the front baffle 400 and the air guide plate 500 are respectively provided at the front and rear sides of the lower air outlet 120 for blocking and guiding to form a lower guide duct 620 extending downward, and the hot air flow blown out through the lower air outlet 120 can be blown downward to the ground under the guidance of the lower guide duct 620, thereby realizing rapid heating regulation of the indoor environment.

[0062] In the first full diffuse wind mode, Fig. 9 and Fig.10As shown, the front baffle 400 is located at the lower avoidance position, and the air guide plate 500 closes the lower air outlet 120. The front baffle 400 slides down to the lower avoidance position avoiding the first air dispersing structure 221 and shielding the front side of the lower air outlet 120, and the air guide plate 500 closes the lower air outlet 120; wherein, the scattered wind dispersed by the first air dispersing structure 221 can be blown out forward, and the scattered wind dispersed by the second air dispersing structure 510 of the air guide plate 500 can be blown out forward and downward, and when the scattered wind airflow encounters the front baffle 400, it can flow downward under the guidance of the front baffle 400. On the one hand, in the first full air dispersing mode, the indoor unit of the air conditioner has the air dispersing outlet forward through the first air dispersing structure 221 and the air dispersing outlet downward through the second air dispersing structure 510, thereby increasing the air dispersing outlet area and air outlet range of the indoor unit of the air conditioner, and improving the air dispersing effect and temperature regulation effect of the indoor unit of the air conditioner. On the other hand, the front baffle 400 is blocked between the first wind dissipation structure 221 and the second wind dissipation structure 510, and the area in front of the air conditioner indoor unit corresponding to the front baffle 400 is approximately a windless zone, and the windless zone is surrounded by the breeze zone blown out by the first wind dissipation structure 221 and the second wind dissipation structure 510 to ensure the temperature regulation effect of the area; the user can be located in the windless zone as needed, and enjoy the comfortable feeling of no wind at a suitable temperature; or, the user can also be located in the breeze zone as needed, to experience the feeling of dispersed wind with near-zero wind feeling and better temperature regulation effect.

[0063] When the wind guide plate 500 is provided with a second wind dispersing structure 510, and the avoidance position includes an upper avoidance position located on the upper side of the first wind dispersing structure 221, the wind dispersing mode also includes a second full wind dispersing mode. In the second full wind dispersing mode, Fig.11 and Fig.12 As shown, the front baffle 400 is located at the upper avoidance position, and the wind guide plate 500 closes the lower air outlet 120. The front baffle 400 slides upward to the area where the upper closed area 210 is located, and the first wind dispersing structure 221 located at the front end plate and the second wind dispersing structure 510 located at the wind guide plate 500 can both discharge air and disperse the airflow, so that the air conditioner has forward wind dispersing through the first wind dispersing structure 221 and forward and downward wind dispersing through the second wind dispersing structure 510. At the same time, since the first wind dispersing structure 221 located at the lower wind dispersing area 220 and the second wind dispersing structure 510 located at the lower air outlet 120 are connected to form an overall wind dispersing structure with a larger wind dispersing area, it can not only increase the wind dispersing area and wind dispersing range of the air conditioner and improve the wind dispersing effect of the air conditioner, but also form a larger breeze feeling area in the front lower area of ​​the air conditioner. Users can be located in the larger breeze feeling area according to their needs to feel the wind blowing with a near-zero wind feeling and a better temperature regulation effect.

[0064] Optionally, in this embodiment, if Figure 2 and Figure 4As shown, the shell 10 includes an inner shell 100 and a panel 200 disposed at the front end of the inner shell 100. A local area of ​​the inner shell 100 is concave at the rear and encloses the wind dispersing duct 300 with the panel 200. The first wind dispersing structure 221 is located in the corresponding area of ​​the panel 200 and the wind dispersing duct 300. This is one of the specific forms of the shell 10. The inner shell 100 encloses the main air duct 110 and the bottom of the inner shell 100 is provided with a lower air outlet 120 as the air duct outlet of the main air duct 110. A local area of ​​the front end plate of the inner shell 100 is concave, and the rest of the area is vertically extended. The panel 200 is blocked at the front end surface of the inner shell 100. The upper closed area 210 of the panel 200 is arranged in affixed with the vertically extended area of ​​the front end plate of the inner shell 100, and the lower wind dispersing area 220 is arranged in affixed with the front end plate of the inner shell 100. The concave areas together form a scattered air duct 300, and a connecting port 310 is formed between the upper edge of the lower air outlet 120 and the panel 200 to connect the scattered air duct 300 and the main air duct 110; at the same time, the panel 200 serves as the front end plate of the entire shell 10, and a first scattered air structure 221 is set in the lower scattered air area 220 of the scattered air duct 300 surrounded by the panel 200, so that the main air duct 110 and the scattered air duct 300 are surrounded by a simple shell 10 structure, which is convenient to process and low in cost.

[0065] In this embodiment, Figure 1 and Figure 3 As shown, the left end plate and the right end plate 130 of the housing 10 and the area corresponding to the wind dispersing duct 300 are provided with auxiliary wind dispersing structures 131. The auxiliary wind dispersing structures 131 are provided at the left and right ends of the wind dispersing duct 300. In the wind dispersing mode, the airflow of the wind dispersing duct 300 is not only dispersed and blown out by the first wind dispersing structure 221 at the front side, but also dispersed and blown out outwards through the auxiliary wind dispersing structures 131 at the left and right ends thereof, thereby increasing the wind dispersing area of ​​the wind dispersing duct 300 and improving the wind dispersing effect and temperature regulation effect in the wind dispersing mode.

[0066] Optionally, the first wind dispersion structure 221, the second wind dispersion structure 510 and the auxiliary wind dispersion structure 131 can adopt a plurality of dispersedly arranged wind dispersion holes, or set mounting holes on the corresponding plate bodies, and rotatably connect impellers in the mounting holes, or other structures that can ventilate and disperse the airflow can be used; wherein, the shape, number and position of the wind dispersion holes in the drawings are shown as examples and are not intended to be actual limitations.

[0067] Specifically, in this embodiment, when the first wind dispersing structure 221 is in the form of wind dispersing holes, Figure 2As shown, the second air dispersion hole can be an offset hole 231. Specifically, the offset hole 231 includes a first hole segment 231a and a second hole segment 231b along the hole depth direction. The plane where one of the radial cross sections of the offset hole 231 is located is the projection plane. The projection of the first hole segment 231a onto the projection plane is the first projection, and the projection of the second hole segment 231b onto the projection plane is the second projection. The first projection partially overlaps with the second projection. The first wind dispersion structure 221 includes a plurality of dispersedly arranged offset holes 231, wherein a first hole segment 231a and a second hole segment 231b of the offset hole 231 have a part of their regions connected and another part of their regions offset, so that a first step surface 231c for blocking a local region of the first hole segment 231a, a connecting area 231d for connecting the first hole segment 231a and the second hole segment 231b, and a second step surface 231e for blocking a local region of the second hole segment 231b can be formed at a connection point of the first hole segment 231a and the second hole segment 231b; in the wind dispersion mode, the airflow of the wind dispersion duct 300 first enters the first hole segment 231a and is initially dispersed, and then the airflow of the first hole segment 231a collides with the first step surface 231c when flowing to the connection point and is dispersed for a second time, and then the airflow flows through the restriction of the connecting area 231d with a reduced flow area and the expansion of the second hole segment 231b with an increased flow area in sequence, so that it is dispersed for the third time and then blown forward. The first wind dispersing structure 221 of this form can perform multiple dispersing processes on the airflow passing through, thereby improving the dispersing effect of the first wind dispersing structure 221 on the airflow, and the first wind dispersing structure 221 has a simple structure and a low processing cost.

[0068] Of course, when the second wind dispersing structure 510 and the auxiliary wind dispersing structure 131 are in the form of wind dispersing holes, the above-mentioned offset holes 231 may also be used.
