DETAILED DESCRIPTION

[0041] 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.

[0042] This embodiment provides an air conditioner indoor unit, such as Figure 1-Figure 4 As shown, the housing 10 and the front baffle 400 are included. The front end plate of the housing 10 is provided with a first wind dispersion structure 230. The housing 10 is provided with a main air duct 110 and a wind dispersion duct 300. The main air duct 110 is connected to the first wind dispersion structure 230 through the wind dispersion duct 300. The front baffle 400 is provided with a second wind dispersion structure 410 and is slidably connected to the front side of the front end plate along the up-down direction of the housing 10. The front baffle 400 has an avoidance position to avoid the first wind dispersion structure 230 and a completely shielding position. The front end surface of the first wind dispersing structure 230 is in the shielding position, and when the front baffle plate 400 is in the shielding position, the projection of the first wind dispersing structure 230 toward the rear panel surface of the front baffle plate 400 completely falls into the covering area of ​​the front baffle plate 400 where the second wind dispersing structure 410 is not set; 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 dispersing structure 230.

[0043] 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 cycle.

[0044] 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 230 located at the front end and used to disperse the airflow passing through, a front baffle 400 for adjusting the air outlet state of the first scattered air structure 230, and an air guide plate 500 for adjusting the air outlet 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.

[0045] 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:

[0046] When the user needs to quickly adjust the indoor temperature, the air guide plate 500 can be opened so that it no longer closes the lower air outlet 120, and the air conditioner enters the fast adjustment mode. At this time, the airflow blown out of the main air duct 110 is almost completely blown out smoothly 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 guide 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 fast adjustment mode, the front baffle 400 can be located in the shielding position, and the shielding area of ​​the front baffle 400 where the second wind dispersion structure 410 is not set can completely cover the first wind dispersion structure 230, so as to cut off the connection between the indoor environment and the wind dispersion duct 300 through the first wind dispersion structure 230, thereby reducing the indoor air flow entering the wind dispersion duct 300 and contacting the cold air flow of the main air duct 110 to form condensation, resulting in the occurrence of condensation and water blowing at the lower air outlet 120, and reducing the air volume loss caused by the air flow branch of the main air duct 110 flowing into the wind dispersion duct 300, thereby correspondingly improving the temperature regulation effect of the air conditioner indoor unit and the air conditioner and the user's comfort; or, the front baffle 400 can also be located in a position where only the shielding area is When the first wind dispersing structure 230 is partially opened or the avoidance position of the first wind dispersing structure 230 is completely avoided, and the avoidance position is located at the lower side of the first wind dispersing structure 230, the front baffle plate 400 extending downward from the front end plate can cooperate with the wind guide plate 500 to guide the airflow blown out from the upper and lower sides 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 230 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 230, 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.

[0047] When the user requires a more gentle airflow outward from the indoor unit of the air conditioner, the air guide plate 500 can be closed to close the lower air outlet 120, and the front baffle 400 can be slid to an avoidance position that partially or completely avoids the first wind dispersion structure 230. 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 230. The wind speed of the blown airflow is relatively small and relatively gentle, thereby improving the user's experience.

[0048] In addition, when the avoidance position is located at the lower side of the first wind dispersion structure 230, the front baffle 400 can also slide down to the avoidance position, the wind guide plate 500 opens and overlaps with the front baffle 400 at the left and right ends to form end air outlets 610, and the air conditioner enters the mixed wind mode. At this time, the first wind dispersion structure 230, the second wind dispersion structure 410 and the end air outlets 610 are all in an open state, and the airflow of the main air duct 110 can be dispersed and blown out through the first wind dispersion structure 230 and the second wind dispersion structure 410, forming a breeze feeling area with a relatively small airflow speed and a relatively large wind dispersion range on the front side of the air conditioner indoor unit. At the same time, the wind is blown directly to the left and right sides through the end air outlets 610 to form a direct blowing wind feeling area with better temperature regulation effect. The user can be located in the breeze feeling area or the direct blowing wind feeling area as needed.

[0049] In the indoor unit of the air conditioner provided in this embodiment, the air guide plate 500 and the front baffle plate 400 can be adjusted to make the air conditioner enter a fast adjustment mode with a larger flow rate and a faster temperature adjustment speed, a diffuse wind mode with a more relaxed air flow, or a mixed wind mode with both a breeze feeling area and a direct wind feeling area; wherein, in the fast 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, and at the same time, the front baffle plate 400 can be adjusted 0 is in the covering position to increase the air volume of the lower air outlet 120, ensure the rapid temperature adjustment of the indoor environment by the air conditioner, and reduce the condensation and water blowing phenomenon of the lower air outlet 120. The front baffle 400 can also be adjusted to the avoidance position of the front end plate extending downward, and on the basis of ensuring the air volume of the lower air outlet 120, the front baffle 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 with better effect. In summary, the optional modes of the air conditioner are rich and diverse, and the front baffle 400 and the air guide plate 500 cooperate with each other in each mode to have a high degree of adjustability in guiding 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.

[0050] When the air conditioner is not in use, the shielding area of ​​the front baffle 400 is larger than the area of ​​the first wind dispersion structure 230. The front baffle 400 can be adjusted to slide to the shielding position in which its shielding area completely covers the first wind dispersion structure 230. At the same time, the air guide plate 500 is adjusted to move to the position of closing 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 230 and the lower air outlet 120 and depositing therein. At the same time, the shielding area of ​​the front baffle 400 covers the front side of the first wind dispersion structure 230, which can simultaneously reduce the deposition and blockage of the first wind dispersion structure 230 caused by dust, and accordingly ensure the normal air outlet and clean air outlet of the first wind dispersion structure 230, thereby ensuring the normal operation of 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 230, the wind dispersion duct 300 and the main air duct 110 when the air conditioner is turned on.

[0051] 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 cooperating with the air guide plate 500 to guide the airflow blown out of the lower air outlet 120 in the above-mentioned quick adjustment mode, and blocking the first wind dispersion structure 230 and the wind dispersion duct 300 from dust and blockage in the shutdown state, 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.

[0052] Optionally, in this embodiment, if Figure 7 and Fig.15 As shown, 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 250 extending in the up-down direction, and the other is provided with a sliding joint slidably engaged in the slide groove 250; the rear side wall of the front baffle 400 is provided with a rack 420 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 420. When the up-down position of the front baffle 400 needs to be adjusted, 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 250 and the meshing driving action of the gear 11 and the rack 420; 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.

[0053] Preferably, there can be two slide grooves 250, which 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 250 one by one, thereby limiting the position 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, there can be two racks 420, which are respectively located at the left and right end areas of the front baffle 400, and there are two gears 11, which are meshed with the two racks 420 one by one, thereby driving the left and right ends of the front baffle 400 to rise and fall to improve the stability of the front baffle 400 sliding up and down relative to the front end plate.

[0054] 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.

[0055] The air guide plate 500 may be hinged to the rear area of ​​the lower air outlet 120. Specifically, the air guide plate 500 is hinged to the rear edge of the lower air outlet 120. A second rotating driving member may be provided on the housing 10. The driving end of the second rotating driving member is connected to the air guide plate 500 to drive the air guide plate 500 to rotate relative to the lower air outlet 120. The first rotating driving member and the second rotating driving member may be motors.

[0056] Specifically, the quick adjustment mode may include a waterproof quick adjustment mode. In the waterproof quick adjustment mode, the front baffle 400 is located in the shielding position, and the air guide plate 500 opens the lower air outlet 120. The front baffle 400 blocks the connection between the indoor environment and the scattered air duct 300, thereby reducing the indoor airflow entering the scattered air duct 300 and contacting with the cold air flow of the main air duct 110 to form condensation, resulting in condensation and water blowing at the lower air outlet 120, and reducing the air volume loss caused by the branch of the airflow from the main air duct 110 flowing into the scattered air duct 300, thereby correspondingly improving the temperature adjustment effect of the air conditioner indoor unit and the air conditioner and the user's comfort. Specifically, as Figure 3 and Figure 4 As shown, the front baffle 400 is located in the blocking position, the air guide plate 500 opens the lower air outlet 120 and extends horizontally forward, so that the air conditioner indoor unit enters the cooling air guide mode. In the cooling air guide mode, 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 air flow blown out through the lower air outlet 120 can be blown forward a longer distance, thereby realizing rapid cooling adjustment of the indoor environment.

[0057] Optionally, in this embodiment, during the up and down sliding stroke of the front baffle 400, the front baffle 400 also has a wind dispersing position. When the front baffle 400 is in the wind dispersing position, the projection of the first wind dispersing structure 230 toward the rear plate surface of the front baffle 400 at least partially overlaps with the area where the second wind dispersing structure 410 is located. The area where the second wind dispersing structure 410 is arranged in the front baffle 400 is the wind dispersing area, and the remaining airtight areas are the covering areas. When the front baffle 400 slides up and down to the wind dispersing position, along the front-to-back direction, the area where the first wind dispersing structure 230 is located partially or completely overlaps with the wind dispersing area of ​​the front baffle 400, and the first wind dispersing structure 230 and the second wind dispersing structure 410 can be connected through the overlapping area of ​​the two.

[0058] Accordingly, the air conditioner has a dual-dispersion air mode. In the dual-dispersion air mode, Figure 5 and Figure 6 As shown, the front baffle 400 is located at the wind dispersing position, and the wind guide plate 500 closes the lower air outlet 120 . The airflow in the main air duct 110 can flow into the scattered air duct 300 through the connecting port 310, and then flow outward through the first scattered air structure 230 and be dispersed for the first time to become primary scattered air; the primary scattered air then flows into the second scattered air structure 410 through the overlapping area of ​​the first scattered air structure 230 and the second scattered air structure 410, wherein the flow cross-section changes in the process of the primary scattered air flowing through the overlapping area, and the primary scattered air is correspondingly dispersed for the second time to become secondary scattered air; the secondary scattered air enters the second scattered air structure 410 and is dispersed for the third time in the process of flowing through it to become tertiary scattered air, and the tertiary scattered air then flows forward through the front port of the second scattered air structure 410, and the scattered air blown out after the three dispersion processes is more dispersed and has a finer airflow, thereby improving the diversity and functionality of the scattered air mode of the air conditioner indoor unit, so that the user can adjust to enter the dual scattered air mode as needed to enjoy a more fine and soothing indoor environment.

[0059] Specifically, in this embodiment, Figure 6As shown, the first wind dispersion structure 230 may include a plurality of dispersedly arranged first wind dispersion holes, and the second wind dispersion structure 410 includes a plurality of dispersedly arranged second wind dispersion holes. When the front baffle 400 is located at the wind dispersion position, the plurality of first wind dispersion holes and the plurality of the second wind dispersion holes correspond to each other one by one, and the projections of the corresponding first wind dispersion holes and the second wind dispersion holes to the rear plate surface of the front baffle 400 partially overlap. The first wind dispersion structure 230 and the second wind dispersion structure 410 both adopt the form of wind dispersion holes, which have good wind dispersion effects and are easy to process. In the dual wind dispersion mode, the front baffle 400 is located at the wind dispersion position, and the corresponding first wind dispersion holes and the second wind dispersion holes are partially staggered, so that the rear end surface of the second wind dispersion hole will partially block the front opening of the first wind dispersion hole to form a step surface, and at the same time, the rear opening of the second wind dispersion hole is connected to the remaining area of ​​the front opening of the first wind dispersion hole to form a channel opening. The process of the airflow passing through the first air dispersion hole is dispersed for the first time to form primary dispersed air. When the primary dispersed air flows to the front end of the first air dispersion hole, it collides with the step surface and is dispersed. At the same time, the flow cross-section changes during the process of flowing through the channel opening, thereby dispersing the primary dispersed air into secondary dispersed air. The secondary dispersed air is then dispersed by the second air dispersion hole to form tertiary dispersed air and flows forward.

[0060] Of course, in some other embodiments, in addition to the above-mentioned air dispersion holes, the first air dispersion structure 230 and the second air dispersion structure 410 may also provide mounting holes on the front end plate or the front baffle 400, and an impeller may be rotatably provided in the mounting holes as an air dispersion structure; or other structures that allow airflow to flow through and disperse it may also be used.

[0061] Specifically, in this embodiment, Figure 2 and Figure 6As shown, the first wind dissipation structure 230 may include a plurality of dispersedly arranged offset holes 231, and the offset holes 231 include a first hole segment 231a and a second hole segment 231b along the hole depth direction, and a plane where one of the radial cross sections of the offset holes 231 is located is a projection plane, a projection of the first hole segment 231a onto the projection plane is a first projection, and a projection of the second hole segment 231b onto the projection plane is a second projection, and the first projection and the second projection partially overlap. The first air dispersion hole is specifically an offset hole 231, and a part of the area of ​​the first hole segment 231a and the second hole segment 231b of the offset hole 231 is connected, and the other part of the area is offset, so the connection between the first hole segment 231a and the second hole segment 231b can form a first step surface 231c for blocking a local area of ​​the first hole segment 231a, a connecting area 231d connecting the first hole segment 231a and the second hole segment 231b, and a second step surface 231e for blocking a local area of ​​the second hole segment 231b; in the air dispersion mode, the airflow of the air 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 the 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 turn, so as to be blown forward after being dispersed for the third time. The first wind dispersing structure 230 of this form can perform multiple dispersing processes on the airflow passing through, thereby improving the dispersing effect of the first wind dispersing structure 230 on the airflow, and the first wind dispersing structure 230 has a simple structure and a low processing cost.

[0062] It should be noted that the shapes, numbers and arrangement positions of the air dispersion holes, staggered holes 231, etc. in the figure are only shown as examples and are not intended to be limiting; in some embodiments, the second air dispersion holes may also be staggered holes 231.

[0063] The front baffle 400 can slide up and down relative to the area where the first wind dispersing structure 230 is located. When the front baffle 400 slides upward to only cover the upper edge area of ​​the first wind dispersing structure 230 or completely avoids the first wind dispersing structure 230 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 230 and the first wind dispersing structure 230 and the second wind dispersing structure 410 are completely misaligned, the front baffle 400 is located in the covering position; when the front baffle 400 slides to cover part or all of the first wind dispersing structure 230 and the first wind dispersing structure 230 and the second wind dispersing structure 410 partially overlap, the front baffle 400 is located in the wind dispersing position; when the front baffle 400 slides downward to only cover the lower edge area of ​​the first wind dispersing structure 230 or completely avoids the first wind dispersing structure 230 without blocking it, the front baffle 400 is located in the lower avoidance position. Among them, in the present application, the up and down sliding stroke of the front baffle 400 includes at least one of an upper avoidance position and a lower avoidance position, and also includes a shielding position and a wind dispersing position, so as to achieve avoidance and complete covering of the first wind dispersing structure 230.

[0064] When the avoidance position includes the lower avoidance position located at the lower side of the first wind dispersing structure 230, the indoor unit of the air conditioner has a mixed air mode and a heating air conduction mode, wherein:

[0065] In mixed air mode, Figure 7 and Figure 8 As shown, the air guide plate 500 opens the lower air outlet 120 and extends forward, the front baffle plate 400 is located at the lower avoidance position, and the front baffle plate 400 overlaps with the air guide plate 500. The air guide plate 500 is rotated downward to open a certain angle, and the front baffle plate 400 slides downward to open, until the bottom end of the front baffle plate 400 overlaps the upper guide surface of the air guide plate 500, or the front end of the air guide plate 500 overlaps the rear side wall of the front baffle plate 400, or the front end of the air guide plate 500 overlaps the bottom end of the front baffle plate 400. At this time, the first wind dispersing structure 230 located at the front end plate and the second wind dispersing structure located at the front baffle plate 400 are both in an open state, and the front baffle plate 400 and the air guide plate 500 jointly block the lower air outlet 120, and the left and right ends of the two form end air outlets 610.

[0066] 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 air guide plate 500 and has a large wind resistance, a part of the airflow of the main air duct 110 flows into the scattered air duct 300 through the connecting port 310, and then is dispersed and blown forward through the first scattered air structure 230; the other part of the airflow is blown out through the lower air outlet 120 and is divided into at least two airflows, one of which is dispersed and blown forward through the second scattered air structure 410 of the front baffle 400, 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 air mode can make the indoor unit of the air conditioner have forward scattered air outlet through the first scattered air structure 230, forward scattered air outlet through the second scattered air structure 410 and quick air outlet to the left and right through the two end air outlets 610, so that the front of the indoor unit of the air conditioner presents a larger breeze feeling area, and the left and right areas of the indoor unit of the air conditioner corresponding to the two end air outlets 610 are direct blowing wind feeling areas with stronger wind force. At the same time, the quick air outlet of the end air outlets 610 can ensure the quick temperature adjustment of the indoor environment by the air conditioner, thereby greatly improving the functionality of the indoor unit of the air conditioner and the air conditioner.

[0067] In the heating and air conduction mode, Fig. 9 and Fig.10 As shown, the front baffle 400 is located at the lower avoidance position, and the air guide plate 500 opens the lower air outlet 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 to the rear edge of the lower air outlet 120. 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 to block and guide the air to form a lower guide air duct 620 extending downward. 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 air duct 620, thereby realizing rapid heating and regulation of the indoor environment.

[0068] Optionally, in this embodiment, if Figure 1-Figure 4As shown, the air guide plate 500 is provided with a third wind dispersing structure 510. When the air guide plate 500 is opened and forms a certain angle with the lower air outlet 120, the setting of the third 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 third 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 air conditioner indoor unit has normal direct air outlet; 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 third wind dispersing structure 510, and the third wind dispersing structure 510 on the air guide plate 500 can disperse the airflow passing through, so that the air conditioner indoor unit has downward and forward downward wind dispersing air outlet, correspondingly improving the diversity of wind dispersing modes and 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 third wind dissipation structure 510 is small, and the third wind dissipation structure 510 can be ensured to be clean and unobstructed, thereby ensuring its wind dissipation function.

[0069] Among them, when the wind guide plate 500 is provided with the third wind dispersion structure 510, in the above-mentioned double wind dispersion mode, a part of the airflow in the main air duct 110 enters the wind dispersion duct 300 and is successively dispersed by the first wind dispersion structure 230 and the second wind dispersion structure 410 and then blown forward, and another part of the airflow is dispersed by the third wind dispersion structure 510 and then blown forward and downward, thereby obtaining a breeze feeling area with finer wind dispersion in the front area of ​​the air conditioner indoor unit and a breeze feeling area with slightly stronger wind feeling located at the front lower side of the air conditioner indoor unit. In the mixed wind mode, part of the airflow in the main air duct 110 can also be dispersed by the third wind dispersion structure 510 and then blown downward, thereby forming a breeze feeling area in the lower area of ​​the air conditioner indoor unit, and correspondingly increasing the range of the breeze feeling area.

[0070] When the wind guide plate 500 is provided with the third wind dispersion structure 510, the wind dispersion mode includes not only the above-mentioned double wind dispersion mode but also a lower wind dispersion mode and a full wind dispersion mode:

[0071] Among them, in the downward scattered wind mode, Figure 1 and Figure 2 As shown, the front baffle 400 is located in the shielding 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 third 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 outlet.

[0072] In the full wind dispersing mode, the front baffle 400 is located in the avoidance position, and the wind guide plate 500 closes the lower air outlet 120. At this time, the first wind dispersing structure 230 and the third wind dispersing structure 510 are in an open state, and the airflow in the main air duct 110 can be dispersed and blown forward through the first wind dispersing structure 230, and blown forward and downward through the third wind dispersing structure 510, thereby forming a relatively large breeze feeling area in front of and below the indoor unit of the air conditioner.

[0073] Specifically, when the wind guide plate 500 is provided with a third wind dispersing structure 510, and the avoidance position includes a lower avoidance position located at the lower side of the first wind dispersing structure 230, the full wind dispersing mode includes a first full wind dispersing mode. In the first full wind dispersing mode, Fig.11 and Fig.12 As 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 230 while 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 230 can be blown out forward, and the scattered wind dispersed by the third 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 230 and the air dispersing outlet downward through the third 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 230 and the third 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 area, and the windless area is surrounded by the scattered wind blown by the first wind dissipation structure 230 and the third wind dissipation structure 510 to ensure the temperature regulation effect of the area; the user can be located in the windless area as needed, and enjoy the comfortable feeling of no wind at a suitable temperature; or, the user can also be located in the wind blowing area as needed, so as to feel the scattered wind with a near-zero wind feeling and a better temperature regulation effect.

[0074] When the wind guide plate 500 is provided with a third wind dispersing structure 510, and the avoidance position includes an upper avoidance position located on the upper side of the first wind dispersing structure 230, the full wind dispersing mode includes a second full wind dispersing mode. In the second full wind dispersing mode, Fig.13 and Fig.14As shown, the front baffle 400 is located at the upper avoidance position, and the air guide plate 500 closes the lower air outlet 120 . The front baffle 400 slides upward to an upper avoidance position avoiding the first wind dispersion structure 230. The first wind dispersion structure 230 located on the front end plate and the third wind dispersion structure 510 located on the air guide plate 500 can both discharge air and disperse the outlet airflow, so that the air conditioner indoor unit has the wind dispersion outlet forward through the first wind dispersion structure 230 and the wind dispersion outlet forward and downward through the third wind dispersion structure 510. At the same time, since the first wind dispersion structure 230 located in the lower wind dispersion area 220 and the third wind dispersion structure 510 located at the lower air outlet 120 are connected to form an overall wind dispersion structure with a larger wind dispersion area, not only can the wind dispersion area and air outlet range of the air conditioner indoor unit be increased and the wind dispersion effect of the air conditioner indoor unit be improved, but also a larger and evenly connected wind dispersion area can be formed in the front lower area of ​​the air conditioner indoor unit. Users can be located in the larger wind dispersion area according to their needs to experience the wind dispersion with a near-zero wind feeling and better temperature regulation effect.

[0075] Specifically, in this embodiment, Figure 1-Figure 4 As shown, the top of the shell 10 is provided with an air inlet, and 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 230 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 230 that can be ventilated. The first wind dispersion structure 230 and the wind dispersion duct 300 therein are close to the main air duct 110 and away from the air inlet at the top of the shell 10. The connectivity between the wind dispersion duct 300 and the main air duct 110 is higher, and the flow resistance is smaller, which can ensure the air volume and temperature regulation effect of the wind dispersion mode, and at the same time effectively reduce the occurrence of the situation that the air outlet of the first wind dispersion structure 230 is easy to flow back upward to the air inlet due to the small distance between the first wind dispersion structure 230 and the air inlet at the top of the shell 10, affecting the temperature regulation effect of the air conditioner.

[0076] When the sliding stroke of the front baffle 400 includes the upper avoidance position, in this embodiment, Fig.13 and Fig.14As shown, along the vertical 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 vertical extension length can further increase the distance between the first wind dispersing structure 230 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 230 to the air inlet, resulting in 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 230 are not blocked by the front baffle 400 and can discharge air and disperse the air, thereby ensuring the wind dispersion effect of the first wind dispersion structure 230 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.

[0077] Among them, when the avoidance position includes the lower avoidance position, such as Figure 1-Figure 6 As shown, the blocking position can be the highest position of the sliding stroke of the front baffle 400. The lower wind dispersion area 220 is recessed relative to the upper closed area 210 to form a receiving groove 240. The receiving groove 240 matches the shape and size of the front baffle 400, and the front baffle 400 is embedded in the receiving groove 240 when it is in the blocking position. The sliding stroke of the front baffle 400 includes a blocking position, a wind dispersing position and a lower avoidance position. The shape and size of the front baffle 400 match the accommodating groove 240. When the front baffle 400 slides upward to the highest position, it is located in the blocking position and completely covers the first wind dispersing structure 230. At the same time, the front baffle 400 is matched and embedded in the accommodating groove 240, which can not only improve the air tightness of the front baffle 400 covering the first wind dispersing structure 230 to reduce the air leakage of the first wind dispersing structure 230, 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.

[0078] Of course, in some other embodiments, the blocking 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, a wind dissipation position and a blocking position; or, the sliding stroke of the front baffle 400 may include an upper avoidance position, a wind dissipation position, a blocking 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 230.

[0079] Optionally, in this embodiment, if Figure 1-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 panel 200 to form a wind dispersing duct 300. The first wind dispersing structure 230 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 a main air duct 110 and a lower air outlet 120 is provided at the bottom of the inner shell 100 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 to fit the vertically extended area of ​​the front end plate of the inner shell 100, and the lower wind dispersing area 220 is arranged to fit 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 230 is set in the lower scattered air area 220 of the panel 200 to form the scattered air duct 300, so that the main air duct 110 and the scattered air duct 300 are enclosed by a simple shell 10 structure, which is convenient to process and low in cost.

[0080] In this embodiment, Figure 1-Figure 4 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 a fourth wind dispersing structure 131. In the wind dispersing mode, the airflow of the wind dispersing duct 300 is dispersed and blown out through the first wind dispersing structure 230 at the front side, and can also be dispersed and blown out through the fourth 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.

[0081] Specifically, the third wind dispersing structure 510 and the fourth wind dispersing structure 131 may also be in the form of wind dispersing holes or impellers.

[0082] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
