Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an indoor unit and an air conditioner. Background Art

[0002] Air conditioners are widely used for temperature regulation in 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 shell and blows air directly with a relatively high airflow intensity, resulting in poor comfort in the direct wind feeling area of ​​the lower air outlet. Based on this, some air conditioners are provided with a scattered wind structure connected to the main air duct and capable of dispersing the air. However, the setting of the scattered wind structure makes it easy for the airflow of the main air duct to form condensation droplets at the connection point when the air conditioner is in direct blowing state, causing droplets to splash outward from the lower air outlet, affecting the user's experience.

DETAILED DESCRIPTION

[0042] 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.

[0043] This embodiment provides an indoor unit such as Figure 1-Figure 4 As shown, it includes a shell 10 and a baffle 400, the front end plate of the shell 10 is provided with a first wind dispersing structure 230, the shell 10 is provided with a main air duct 110 and a wind dispersing duct 300, the upper edge of the lower air outlet 120 of the main air duct 110 is formed with a connecting port 310, and the wind dispersing duct 300 is connected between the first wind dispersing structure 230 and the connecting port 310; the baffle 400 includes a front baffle plate 410 and a bottom baffle plate 420 provided at the bottom end of the front baffle plate 410, and the front baffle plate is connected to the front end plate in a sliding manner in the up and down direction. On the front side, the front baffle plate 410 has a covering position that completely covers the first wind dispersing structure 230 and a avoiding position that avoids the first wind dispersing structure 230 downward; the bottom baffle plate 420 extends into the main air duct 110 through the lower air outlet 120, and when the front baffle plate 410 is in the covering position, the bottom baffle plate 420 closes the connecting port 310; the shell 10 is provided with an air guide plate 500 for closing or opening the lower air outlet 120, 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.

[0044] This embodiment also provides an air conditioner, including an outdoor unit and the indoor unit mentioned above, and the indoor unit and the outdoor unit are connected through a refrigerant pipe to form a refrigerant circulation system.

[0045] The indoor unit and the air conditioner provided in this embodiment, wherein the 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 baffle 400 for adjusting the opening and closing state of the first scattered air structure 230 and the connecting port 310, 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 outdoor unit for heat exchange with the outdoor environment and the above-mentioned indoor unit for adjusting the temperature of the indoor environment.

[0046] When the air conditioner needs to be used, the air guide plate 500 and the stopper 400 can be adjusted as needed to make the indoor unit enter different air outlet modes:

[0047] When users need to quickly adjust the indoor temperature, such as Figure 1 and Figure 2As shown, the front baffle 410 can be adjusted to slide to the covering position and the air guide plate 500 can be opened to put the air conditioner into the fast adjustment mode. At this time, the front baffle 410 completely covers and closes the first wind dispersion structure 230, and at the same time the bottom baffle 420 closes the connecting port 310, and the airflow blown out of the main air duct 110 is completely and smoothly blown out through the lower air outlet 120 in the open state, thereby realizing the 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. Among them, in the fast adjustment mode, when the airflow of the main air duct 110 is blown outward through the lower air outlet 120, the front baffle 410 covers and blocks the first wind dispersing structure 230, and at the same time, the bottom baffle 420 closes the connecting port 310, which can double-block the wind dispersing duct 300 and the main air duct 110, thereby effectively reducing the air in the indoor environment from entering the wind dispersing duct 300 through the first wind dispersing structure 230 and contacting the cold airflow of the main air duct 110 at the connecting port 310 to form condensed water, resulting in the lower air outlet 120 The occurrence of outward splashing of droplets can correspondingly improve the comfort level of the indoor unit and the air conditioner; at the same time, the bottom baffle 420 closes the connecting port 310, which can also reduce the occurrence of vortexes and howling caused by the air flow branch in the main air duct 110 flowing into the scattered air duct 300 through the connecting port 310, thereby ensuring the air volume of the main air duct 110 and the temperature regulation effect of the indoor unit on the indoor environment, as well as improving the quietness of the indoor unit, further improving the comfort level of the indoor unit and the air conditioner.

[0048] When the user needs the indoor unit to blow out a more gentle airflow, such as Figure 5 and Figure 6As shown, the air guide plate 500 can be opened and the front baffle plate 410 can be slid to the avoidance position avoiding the first wind dispersing structure 230. The bottom baffle plate 420 overlaps the front end of the air guide plate 500 and no longer blocks the connecting port 310. The air conditioner enters the mixed air mode. Since the lower air outlet 120 is blocked by the air guide plate 500 and the front baffle plate 410, and the air guide plate 500, the front baffle plate 410 and the left and right ends of the shell 10 form an end air outlet 610, a part of the airflow in the main air duct 110 can flow into the wind dispersing duct 300 through the connecting port 310. Then, the air is dispersed by the first wind dispersing structure 230 and then blown forward; another part of the airflow in the main air duct 110 is blown to the left and right sides through the two end air outlets 610 as shown by the dotted arrows, thereby forming a breeze feeling area with low wind speed and low noise in front of the indoor unit to meet the user's comfort level, and at the same time, a direct blowing wind feeling area with fast air outlet is formed on the left and right sides of the indoor unit to ensure the air volume of the indoor unit and its temperature regulation effect on the indoor environment, which further ensures the user's comfort level and improves the functionality of the indoor unit and the air conditioner. Among them, the bottom baffle 420 overlaps with the upper guide surface of the air guide plate 500, and the connection between the two is highly airtight, which can reduce the airflow from leaking forward through the connection between the two, thereby affecting the air supply and generating noise.

[0049] In the indoor unit provided in this embodiment, the air guide plate 500 and the baffle 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 mixed air mode with a relatively slow front airflow. The operation modes are diverse and the functionality is strong. In the quick adjustment mode, the front baffle 410 and the bottom baffle 420 respectively cover and block the first wind dispersion structure 230 and the connecting port 310, which can double-block the wind dispersion duct 300 and the main air duct 110, thereby effectively reducing the formation of condensed water at the connecting port 310, which causes the lower air outlet 120 to splash out droplets. At the same time, it can also reduce the occurrence of vortices and howling caused by the airflow branch in the main air duct 110 flowing into the wind dispersion duct 300, thereby ensuring the temperature regulation effect of the indoor unit on the indoor environment and the silent operation effect, and correspondingly improving the comfort of the indoor unit and the air conditioner.

[0050] When the air conditioner is not needed, Figure 3 and Figure 4As shown, the covering area of ​​the front baffle 410 is larger than the area of ​​the first wind dispersion structure 230. The front baffle 410 can be adjusted to slide to a covering position that completely covers the first wind dispersion structure 230, and the air guide plate 500 can be 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 230 and the lower air outlet 120 and depositing therein. At the same time, the front baffle 410 blocks 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, thereby ensuring the normal operation of the first wind dispersion structure 230, the 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 410 is slidably connected to the front side of the front end plate in the up and down directions, and the front baffle plate 410 can be disassembled and maintained from the outside, and the disassembly and assembly are convenient, and the setting and sliding of the front baffle plate 410 do not occupy the internal space of the shell 10 and the space outside the shell 10, thereby ensuring the arrangement of the dispersion air duct 300 and the main air duct 110 inside the shell 10 and the arrangement of other items outside the shell 10, thereby reducing the overall volume of the indoor unit and the space it occupies.

[0052] Optionally, in this embodiment, if Figure 5 and Fig.17 As shown, one of the rear side wall of the front baffle 410 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 410 is provided with a rack 430 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 430. When it is necessary to adjust the up-down position of the front baffle 410, 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 410 slides upward under the sliding engagement between the sliding joint and the slide groove 250 and the meshing drive of the gear 11 and the rack 430; 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 410 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 end parts of the front baffle 410 to improve the stability of the front baffle 410 slidingly connected to the front end plate; similarly, there can be two racks 430, which are respectively located at the left and right end areas of the front baffle 410, and there are two gears 11, which are meshed with the two racks 430 one by one, thereby driving the left and right end parts of the front baffle 410 to rise and fall to improve the stability of the front baffle 410 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 on the shell 10, and the driving end of the telescopic driving component is connected to the front baffle 410 to drive its lifting movement.

[0055] 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.

[0056] Optionally, in this embodiment, if Figure 3 and Figure 4 As shown, the air guide plate 500 may be configured as a second air dissipation structure 510 in addition to being a closed plate. When the air guide plate 500 opens the lower air outlet 120 and forms a certain angle with the lower air outlet 120, the setting of the second wind dispersing structure 510 has little or no effect on the smoothness of the guide surface of the air guide plate 500. Based on the larger wind resistance of the second wind dispersing structure 510, the airflow blown out through the lower air outlet 120 preferentially flows out through the upper guide surface of the air guide plate 500, thereby ensuring the guidance of the air out of the lower air outlet 120 when the air guide plate 500 is opened, so that the 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 out through the second wind dispersing structure 510, and the wind dispersing structure formed by the multiple second wind dispersing structures 510 on the air guide plate 500 can disperse the airflow passing through, so that the indoor unit has downward and forward downward wind dispersing air outlet. 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.

[0057] Similarly, in this embodiment, the front baffle 410 is configured as a closed plate. Figure 7-Figure 12 As shown, a third wind dispersing structure 411 may also be provided, and when the front baffle 410 is located at the covering position, the area of ​​the front baffle 410 different from the third wind dispersing structure 411 completely covers the first wind dispersing structure 230 .

[0058] For different settings of the air guide plate 500 and the front baffle plate 410, the indoor unit can enter multiple operation modes by adjusting the positions of the baffle 400 and the air guide plate 500:

[0059] Specifically, when both the air guide plate 500 and the front baffle plate 410 are closed plates or are provided with a wind dispersion structure, the air conditioner has a quick adjustment mode. In the quick adjustment mode, the front baffle plate 410 is in the covering position and can cover and close the first wind dispersion structure 230, the bottom baffle plate 420 closes the connecting port 310, and the air guide plate 500 opens the lower air outlet 120. The airflow of the main air duct 110 can be almost completely blown out through the lower air outlet 120 and along the upper guide surface of the air guide plate 500. At the same time, it can reduce the condensation water and vortex formed by the airflow of the main air duct 110 at the connecting port 310 and the wind dispersion duct 300, thereby correspondingly improving the temperature regulation effect and the quiet effect of the indoor unit, and reducing the splashing of droplets at the lower air outlet 120. Specifically, in the cooling air guide mode, Figure 1 and Figure 2 As shown, the front baffle 410 is in the covering position, and the air guide plate 500 opens the lower air outlet 120 and extends forward; 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 achieving rapid cooling regulation of the indoor environment.

[0060] When the air guide plate 500 is provided with a second air dispersion structure 510 and the front baffle plate 410 is a closed plate, in addition to the above-mentioned fast adjustment mode, the indoor unit also has a first downward air dispersion mode and a first mixed air mode:

[0061] Among them, in the first scattered wind mode, Figure 3 and Figure 4As shown, the front baffle 410 is located in the covering position, and the air guide plate 500 closes the lower air outlet 120 . At this time, the front baffle 410 closes the first wind dispersion structure 230, and the bottom baffle 420 closes the connecting port 310, so that the front baffle 410 and the bottom baffle 420 can respectively block the connection between the wind dispersion duct 300 and the indoor environment and the connection between the main air duct 110 and the wind dispersion duct 300, and the airflow of the main air duct 110 is all blown outward through the second wind dispersion structure 510 and is broken up during the blowing process, thereby forming a breeze feeling area with a slow wind speed at the front and lower part of the indoor unit; and under the partition effect of the front baffle 410 and the bottom baffle 420, the airflow of the main air duct 110 entering the wind dispersion duct 300 to form vortices and howling, and the airflow of the wind dispersion duct 300 forming condensation droplets at the connecting port 310, causing the lower air outlet 120 to splash droplets outward, can be effectively reduced, thereby improving the temperature regulation effect, quiet effect and use comfort of the indoor unit.

[0062] In the first mixed air mode, Figure 5 and Figure 6 As shown, the air guide plate 500 is opened to a first preset angle, the front baffle 410 is located in the avoidance position, and the bottom baffle 420 overlaps the upper guide surface of the air guide plate 500; the air guide plate 500 rotates downward to open the first preset angle, and the front baffle 410 slides downward to open the first wind dispersion structure 230, until the bottom baffle 420 overlaps the upper guide surface of the air guide plate 500, at this time, the first wind dispersion structure 230 and the connecting port 310 are both in an open state, the front baffle 410 and the air guide plate 500 jointly block the lower air outlet 120 and the left and right ends of the two form an end air outlet 610; when the air conditioner is running, 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 flows into the first wind dispersion structure 230 through the first wind dispersion structure 230. The structure 230 disperses and blows forward, thereby forming a breeze feeling area with dispersed wind in front of the indoor unit and the area corresponding to the first wind dispersing structure 230; another part of the airflow of the main air duct 110 is blown out through the lower air outlet 120 and divided into two airflows, one of which is dispersed and blown downward through the second wind dispersing structure 510, thereby forming a breeze feeling area below the indoor unit, and at the same time, 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, forming a direct blowing wind feeling area with strong wind force on the left and right sides of the indoor unit; at the same time, under the shielding and partition of the front baffle 410, the indoor unit and its corresponding front lower area form a windless feeling area, and the windless feeling area is located between the above two breeze feeling areas. Users can be located in the breeze feeling area, the direct blowing wind feeling area or the windless area according to their needs, with many options and high user experience. At the same time, the rapid air outlet of the end air outlet 610 can ensure the rapid temperature adjustment of the indoor environment by the air conditioner, thereby greatly improving the functionality of the indoor unit and the air conditioner.

[0063] When the air guide plate 500 is provided with the second air dispersion structure 510 and the front baffle 410 is provided with the third air dispersion structure 411, the indoor unit has a second downward air dispersion mode, a second mixed air mode and a double air dispersion mode:

[0064] Among them, in the second diffuse wind mode, if Figure 7 and Figure 8 As shown, the positions of the baffle 400 and the air guide plate 500 are the same as those in the first downward air dispersion mode, and the covering area of ​​the front baffle 410 can close the first air dispersion structure 230, and its air outlet condition is the same as that in the first downward air dispersion mode, which will not be repeated here.

[0065] Among them, in the second mixed air mode, Fig. 9 and Fig.10 As shown, the positions of the front baffle 410 and the air guide plate 500 are the same as those in the first mixed air mode, with the only difference being that the airflow blown out through the lower air outlet 120 is divided into three streams, one of which is blown downward through the second wind dispersion structure 510 to form a breeze feeling area, another is blown to the left and right sides through the two end air outlets 610 to form a straight blowing wind feeling area, and another stream can enter the third wind dispersion structure 411 to be blown forward and dispersed to form a breeze feeling area, then the first wind dispersion structure 230, the third wind dispersion structure 411 and the second wind dispersion structure 510 form a continuous wind dispersion area on the front side of the indoor unit, and correspondingly form a continuous and large-scale breeze feeling area in front of the indoor unit; at the same time, the rapid air outlet of the end air outlet 610 can ensure rapid temperature regulation of the indoor environment by the air conditioner.

[0066] For the dual diffuse wind mode, Fig.11 and Fig.12 As shown, the front baffle 410 has a wind dispersing position in addition to the avoidance position and the covering position. When the front baffle 410 is in the wind dispersing position, the projection of the first wind dispersing structure 230 toward the front baffle 410 at least partially overlaps with the area where the third wind dispersing structure 411 is located, and the bottom baffle 420 opens the connecting port 310. In the double wind dispersing mode, the air guide plate 500 opens the second preset angle, the front baffle 410 is in the wind dispersing position, and the bottom baffle 420 overlaps the upper guide surface of the air guide plate 500. The second preset angle is smaller than the first preset angle, and the bottom baffle 420 only needs to slide downward and no longer close the connecting port 310. At this time, the overlapping area of ​​the first wind dispersing structure 230 and the third wind dispersing structure 411 can form a double dispersing channel, and the air guide plate 500 blocks the lower air outlet 120 and its two ends form smaller end outlets with the housing 10.

[0067] A portion of the airflow in the main air duct 110 flows into the scattered air duct 300 through the connecting port 310, and then flows outward through the first scattered air structure 230 and is dispersed by it for the first time to become the primary scattered air; the primary scattered air then flows into the third scattered air structure 411 through the overlapping area of ​​the first scattered air structure 230 and the third scattered air structure 411, wherein the flow cross section of the primary scattered air changes during the process of flowing through the overlapping area, and the primary scattered air is correspondingly dispersed for the second time to become the secondary scattered air; the secondary scattered air enters the third scattered air structure 411 and is dispersed for the third time during the process of flowing through it to become the third scattered air The three times of scattered wind then flow out forward through the front port of the third wind dispersion structure 411, forming a breeze feeling area after three times of dispersion treatment in front of the indoor unit, in which the scattered wind is more dispersed and the airflow is more dense; another part of the airflow in the main air duct 110 is mainly dispersed downwardly and forwardly through the second wind dispersion structure 510 and then blown forward, forming a breeze feeling area after a single third treatment in the front lower part of the indoor unit; thereby improving the diversity and functionality of the wind dispersion mode of the indoor unit, and the user can adjust to enter the double wind dispersion mode as needed to enjoy an indoor environment with a finer wind feeling.

[0068] Specifically, the bottom baffle 420 and the front baffle 410 of the baffle 400 can be integrally formed, or fixedly connected by welding, riveting, etc. In addition to the above forms, in this embodiment, the bottom baffle 420 can also be hinged to the bottom end of the front baffle 410, and the bottom baffle 420 has a bending position perpendicular to the front baffle 410 and a lower wind guide position parallel to the front baffle 410. The bottom baffle 420 is hinged to the front baffle 410, and the two can rotate relative to each other to form different angles, wherein there may be a certain resistance at the hinge between the bottom baffle 420 and the front baffle 410, and when in use, the rotation angle of the bottom baffle 420 relative to the front baffle 410 can be manually adjusted; or a third rotation driving member can be provided on the front baffle 410, and the driving end of the third rotation driving member is connected to the bottom baffle 420, and is used to drive the bottom baffle 420 to rotate to adjust its rotation angle relative to the front baffle 410.

[0069] When the air guide plate 500 is a closed plate or is provided with a second air dissipation structure 510, the indoor unit has a heating air guide mode. In the heating air guide mode, Fig.13 and Fig.14As shown, the front baffle 410 is located at the avoidance position, the bottom baffle 420 is located at the lower wind guiding position, and the wind guiding plate 500 opens the lower air outlet 120 and extends downward. Although the bottom baffle 420 does not close the connecting opening 310, the wind resistance of the lower air outlet 120 in the field state is less than that of the wind duct 300, and the airflow of the main duct 110 is mainly blown out through the lower air outlet 120. The air guide plate 500 is hinged at the rear edge area of ​​the lower air outlet 120. The extended baffle and air guide plate 500 formed by the connection of the front baffle 410 and the bottom baffle 420 are respectively used for blocking and guiding at the front and rear sides of the lower air outlet 120 to form a downwardly extending lower guide duct 620. 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 and regulation of the indoor environment; wherein, the downwardly extending bottom baffle 420 can lengthen the front baffle 410, further improve the downward guiding effect of the baffle 400, and correspondingly further improve the heating effect of the indoor unit on the indoor environment.

[0070] When the air guide plate 500 is provided with the second air dispersion structure 510, the indoor unit has a full air dispersion mode. In the full air dispersion mode, Fig.15 and Fig.16 As shown, the front baffle 410 is located at the avoidance position, the bottom baffle 420 is located at the lower wind guiding position, and the wind guide plate 500 closes the lower air outlet 120. When in use, the wind guide plate 500 can be opened, and then the bottom baffle 420 is adjusted to rotate downward to a vertical state to reach the lower wind guiding position, and then the front baffle 410 is adjusted to slide down to the avoidance position, and the wind guide plate 500 rotates to close the lower air outlet 120 again; when the indoor unit is running, a part of the airflow of the main air duct 110 can enter the wind dispersing duct 300, and is blown forward after being dispersed by the first wind dispersing structure 230, forming a breeze feeling area in front of the indoor unit; another part of the airflow of the main air duct 110 is dispersed by the second wind dispersing structure 510 and blown forward and downward, and at the same time blown downward under the guiding effect of the extended baffle, forming a breeze feeling area below the indoor unit; wherein, under the blocking effect of the front baffle 410, the area on the front side of the indoor unit corresponding to the front baffle 410 forms a windless feeling area.

[0071] The arrangement in which the bottom baffle 420 is hinged to the front baffle 410 can enable the indoor unit to have more diverse operating modes, thereby improving the functionality of the indoor unit and the air conditioner and the selectivity of the user.

[0072] Specifically, in this embodiment, Figure 8 and Fig.12As shown, the first wind dispersing structure 230 includes a plurality of dispersedly arranged displaced holes 231, and the displaced 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 displaced hole 231 is located is a projection plane, and 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 wind dispersing structure 230 includes a plurality of dispersedly arranged wind dispersing holes, and the wind dispersing holes are specifically displaced holes 231, and a part of the area of ​​the first hole segment 231a and the second hole segment 231b of the displaced hole 231 is connected, and another part of the area is staggered, then 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 for connecting the first hole segment 231a and the second hole segment 231b, and a connecting area 231d for connecting the second hole segment 231a and the second hole segment 231b. The second step surface 231e is used to block the local area of ​​the section 231b; in the mixed wind mode or the double wind dispersion mode, the airflow of the wind dispersion duct 300 first enters the first hole section 231a and is initially dispersed, and then the airflow of the first hole section 231a collides with the first step surface 231c when it flows to the connection point and is dispersed for the second time, and then the airflow flows through the constriction of the connecting area 231d with a reduced flow area and the expansion of the second hole section 231b with an increased flow area in turn, and is then dispersed for the third time and blown forward. Then, the first wind dispersion structure 230 of this form can disperse the airflow passing through multiple times, thereby improving the dispersion effect of the first wind dispersion structure 230 on the airflow, and the first wind dispersion structure 230 has a simple structure and low processing cost.

[0073] Of course, in addition to the above-mentioned staggered holes 231, the first wind dispersion structure 230 may also adopt a straight hole form, or the first wind dispersion structure 230 may also adopt an impeller form. Specifically, a mounting hole may be set on the front end plate, and the impeller may be rotatably connected in the mounting hole; the second wind dispersion structure 510 and the third wind dispersion structure 411 may similarly adopt straight hole forms of wind dispersion holes, staggered holes 231 forms of wind dispersion holes or impeller forms, etc., which can achieve the dispersion of the airflow.

[0074] It should be noted that the shapes, numbers and arrangement positions of the air diffusion holes, through holes, offset holes 231, etc. in the figure are only shown for example and are not intended to be limiting.

[0075] In this embodiment, Figure 1-Figure 4As 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 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 wind duct 110 and away from the air inlet at the top of the shell 10. The connectivity of the wind dispersion duct 300 and the main wind 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 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, which affects the temperature regulation effect of the air conditioner.

[0076] Specifically, in this embodiment, Figure 3-Figure 6 As shown, the lower wind dispersing area 220 is concave relative to the upper closed area 210 to form a receiving groove 240, and the front baffle 410 is embedded in the receiving groove 240 when it is in the covering position. The sliding stroke of the front baffle 410 includes the covering position, the wind dispersing position and the avoidance position from top to bottom. The shape and size of the front baffle 410 match the receiving groove 240. When the front baffle 410 slides upward to the highest position, it is located in the covering position and completely covers the first wind dispersing structure 230. At the same time, the front baffle 410 is matched and embedded in the receiving groove 240, which can not only improve the air tightness of the front baffle 410 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 410 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 when the indoor machine is turned off.

[0077] 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.

[0078] In this embodiment, Figure 1-Figure 4 As shown, the left end plate and / or the right end plate 130 of the housing 10 and the area corresponding to the wind dispersing duct 300 are provided with an auxiliary wind dispersing structure 131. Specifically, the auxiliary wind dispersing structure 131 may include a plurality of dispersedly arranged wind dispersing holes, and the left and right ends of the wind dispersing duct 300 are provided with a plurality of dispersedly arranged wind dispersing holes. 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 wind dispersing holes 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.
