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 blowing wind area of ​​the lower air outlet. Based on this, some air conditioners are provided with a dispersing wind structure that is connected to the main air duct and can disperse the air. However, the dispersing wind structure is easily blocked by dust deposition and cannot play a dispersing role. In addition, the existence of the dispersing 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. Utility Model Content

[0003] The purpose of the utility model includes providing an indoor unit and an air conditioner to solve the technical problems that the wind dispersion structure in the existing air conditioner is easily blocked by dust deposition and becomes ineffective, and the existence of the wind dispersion structure makes it easy for the air conditioner to blow liquid outward in the direct blowing state.

[0004] In order to solve the above problems, the utility model provides an indoor unit, comprising:

At the same time, it can also reduce the occurrence of vortices and howling formed by the airflow branch in the main air duct flowing into the diffuse wind duct, thereby ensuring the temperature adjustment effect of the indoor unit on the indoor environment and the silent operation effect, and correspondingly improving the comfort of use of the indoor unit and the air conditioner.

[0009] When the air conditioner is not in use, the front baffle can completely cover the first air dispersion structure, the bottom baffle can close the connecting port, and at the same time, the air guide plate can be adjusted to move to a position to close the lower air outlet, thereby reducing the occurrence of pollution and blockage caused by external dust entering the air dispersion duct and the main air duct through the first air dispersion structure and the lower air outlet and depositing therein. At the same time, the front baffle blocks the front side of the first air dispersion structure, which can simultaneously reduce the deposition and blockage of the first air dispersion structure caused by dust, thereby ensuring the normal operation of the first air dispersion structure, the indoor unit and the air conditioner, and reducing the occurrence of secondary pollution to the indoor environment caused by dust deposited in the first air dispersion structure, the air dispersion duct and the main air duct when the air conditioner is turned on.

DETAILED DESCRIPTION

[0048] 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.

[0049] This embodiment provides an indoor unit such as Figure 1-Figure 4As shown, it includes a shell 10, an air guide plate 500 and a blocking member 400, wherein the front end plate of the shell 10 is provided with a first air dispersion structure 230, a main air duct 110 and an air dispersion duct 300 are provided in the shell 10, a connecting port 310 is formed on the upper edge of the lower air outlet 120 of the main air duct 110, and the air dispersion duct 300 is connected between the first air dispersion structure 230 and the connecting port 310; the air guide plate 500 is connected to the shell 10, and is used to close or open the lower air outlet 120; the blocking member 400 It includes a rotating shaft 430 and a front baffle 410 and a bottom baffle 420 linked to the rotating shaft 430. The rotating shaft 430 is rotatably connected to the lower edge of the front end plate and extends in the left and right directions. When the rotating shaft 430 rotates to a first rotation position, the front baffle 410 covers the first wind dispersing structure 230 at the front side, and the bottom baffle 420 closes the connecting port 310. When the rotating shaft 430 rotates to a second rotation position, the front baffle 410 avoids the first wind dispersing structure 230, and the bottom baffle 420 opens the connecting port 310.

[0050] 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.

[0051] 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.

[0052] When the air conditioner needs to be used, the air guide plate 500 and the baffle 400 can be adjusted as needed to make the indoor unit enter different air outlet modes:

[0053] When the user needs to quickly adjust the indoor temperature, the user can adjust the shaft 430 to rotate to the first position and open the air guide plate 500 to put the air conditioner into the quick adjustment mode. The front baffle 410 and the bottom baffle 420 move in conjunction with the rotation of the shaft 430, so that 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 blown 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 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.

[0054] When the user needs a more relaxed airflow blown out by the indoor unit, the user can adjust the rotating shaft 430 to the second position, and at the same time adjust the wind guide plate 500 to close the connecting port 310, and the air conditioner enters the wind dispersion mode. At this time, the front baffle 410 rotates downward and no longer blocks the first wind dispersion structure 230 at the front side. At the same time, the bottom baffle 420 no longer closes the connecting port 310. Since the lower air outlet 120 is closed by the wind guide plate 500, the airflow in the main air duct 110 can flow into the wind dispersion duct 300 through the connecting port 310, and then be dispersed by the first wind dispersion structure 230 and blown forward, thereby forming a breeze feeling area with lower air flow speed and lower noise in front of the indoor unit, thereby improving the user's experience.

[0055] 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 fast adjustment mode with a larger flow rate and a faster temperature adjustment speed, or a dispersing wind mode with a relatively slow airflow blowing out from the front, with diverse operating modes and strong functionality; and in the fast adjustment mode of direct airflow, the front baffle 410 and the bottom baffle 420 respectively cover and block the first dispersing wind structure 230 and the connecting port 310, which can double-block the dispersing wind duct 300 and the main wind 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, and at the same time, it can also reduce the airflow branch in the main air duct 110 flowing into the dispersing wind duct 300 to form vortices and howling, thereby ensuring the temperature adjustment 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.

[0056] When the air conditioner is not in use, the covering area of ​​the front baffle 410 is larger than the area of ​​the first wind dispersing structure 230. The rotating shaft 430 can be adjusted to rotate to the first rotation position so that the front baffle 410 completely covers the first wind dispersing structure 230 and the bottom baffle 420 closes the connecting port 310. 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 external dust from entering the wind dispersing duct 300 and the main air duct 110 through the first wind dispersing structure 230 and the lower air outlet 120 and depositing therein to cause pollution and blockage. At the same time, the front baffle 410 blocks the front side of the first wind dispersing structure 230, which can simultaneously reduce the deposition and blockage of the first wind dispersing structure 230 caused by dust, thereby ensuring the normal operation of the first wind dispersing structure 230, the indoor unit and the air conditioner, and reducing the dust deposited in the first wind dispersing structure 230, the wind dispersing duct 300 and the main air duct 110 when the air conditioner is turned on and running, causing secondary pollution to the indoor environment.

[0057] It should be noted that, when the turning angle between the front baffle plate 410 and the front end plate is greater than or equal to 60°, the shielding effect of the front baffle plate 410 on the first wind dispersion structure 230 on the front end plate is relatively weak, indicating that the front baffle plate 410 has avoided the first wind dispersion structure 230; preferably, the turning angle between the front baffle plate 410 and the front end plate is greater than or equal to 90°, and along the front-to-back direction, the projection areas of the front baffle plate 410 and the first wind dispersion structure 230 onto the same vertical plane are different and there is no overlapping area, that is, the front baffle plate 410 will not completely shield the first wind dispersion structure 230 at the front side, so as to ensure the air output of the first wind dispersion structure 230 in the wind dispersion mode.

[0058] In addition, the linkage connection between the front baffle 410 and the bottom baffle 420 of the baffle 400 means that only a single first rotating drive member is required to drive the rotating shaft 430 to rotate, and the front baffle 410 and the bottom baffle 420 will achieve synchronous or asynchronous linkage under the rotation of the rotating shaft 430. This setting only requires a single first rotating drive member on the basis of realizing different positions and closed states of the front baffle 410 and the bottom baffle 420 in different modes, and has a simple structure and strong functionality.

[0059] Specifically, the air guide plate 500 can be hinged to the rear edge area of ​​the lower air outlet 120, and the shell 10 can be provided with a second rotating drive member connected to the air guide plate 500 to drive the air guide plate 500 to rotate to open or close the lower air outlet 120; wherein, both the first rotating drive member and the second rotating drive member can be motors.

[0060] Specifically, in this embodiment, Fig.19 As shown in the figure, both the front baffle 410 and the bottom baffle 420 are fixed to the rotating shaft 430. The front baffle 410 and the bottom baffle 420 are arranged at an angle and are fixedly connected by the rotating shaft 430. When in use, the rotation of the rotating shaft 430 can drive the front baffle 410 and the baffle bar to rotate synchronously with it, thereby realizing the linkage connection between the front baffle 410 and the bottom baffle 420; specifically, the angle of the front baffle 410 and the bottom baffle 420 is related to the angle of the front end plate and the connecting port 310. When the front baffle 410 extends vertically and the connecting port 310 extends horizontally, the angle of the front baffle 410 and the bottom baffle 420 can range from 80° to 100°, preferably 90°.

[0061] The following is a detailed introduction to the operation mode of this type of indoor unit:

[0062] By adjusting the positions of the baffle 400 and the air guide plate 500, the indoor unit has at least a quick adjustment mode, a wind blocking quick adjustment mode, a cooling air guide mode and a wind dispersion mode:

[0063] Among them, in the fast adjustment mode, such as Figure 1 and Figure 2As shown, the rotating shaft 430 is located in the first rotation position, and the air guide plate 500 opens the lower air outlet 120; at this time, the front baffle 410 closes the first wind dispersion structure 230 at the front side to block the scattered air duct 300 from the indoor environment; the bottom baffle 420 closes the connecting port 310 to block the scattered air duct 300 and the main air duct 110. Under the dual blocking effect of the front baffle 410 and the bottom baffle 420, the airflow of the main air duct 110 is almost completely blown outward through the lower air outlet 120, and during the direct blowing process, the indoor air cannot contact the cold airflow of the main air duct 110 through the first wind dispersion structure 230 and the scattered air duct 300, and the airflow of the main air duct 110 cannot flow into the scattered air duct 300 to cause air volume loss and noise pollution, thereby ensuring the air volume and rapid adjustment of the indoor environment temperature, reducing the occurrence of water blowing outward and noise pollution during the direct blowing process, and correspondingly improving the functionality and use comfort of the indoor unit and the air conditioner.

[0064] In the windshield quick adjustment mode, Figure 3 and Figure 4 As shown, the angle range between the front baffle 410 and the front end plate is [45°, 90°), and the air guide plate 500 opens the lower air outlet 120; in the direct blowing state with the air guide plate 500 opened, in addition to the above-mentioned fast adjustment mode, the front baffle 410 can also be adjusted to rotate outward relative to the front end plate [45°, 90°), and the airflow of the main air duct 110 blows directly outward through the lower air outlet 120. The front baffle 410 extending forward and outward can play a blocking role on the upper side of the lower air outlet 120 to reduce the adverse effects of the airflow blown out of the lower air outlet 120 flowing back upward to the air inlet at the top of the shell 10 on the effective air volume and temperature regulation effect of the indoor unit. This mode is particularly suitable for long-distance air supply. Specifically, the air guide plate 500 extends horizontally forward or forward and upward, and the front baffle 410 and the air guide plate 500 guide the airflow on the upper and lower sides of the lower air outlet 120, respectively, thereby reducing the airflow backflow and increasing its air supply distance.

[0065] In cooling air flow mode, Figure 5 and Figure 6 As shown, the front baffle 410 opens the first wind dissipation structure 230 and extends forward, and the air guide plate 500 opens the lower air outlet 120 and extends forward; the front baffle 410 rotates from vertical to forward, and the rotation angle between the front baffle 410 and the front end plate is approximately 90°. Synchronously, the bottom baffle 420 rotates from horizontal to vertical and no longer closes the connecting port 310. The airflow of the main air duct 110 is mainly blown out through the lower air outlet 120. The front baffle 410 and the air guide plate 500 respectively block and guide the lower air outlet 120 to form a front guide duct 610 extending forward. The cold airflow directly blown through the lower air outlet 120 can be blown forward a longer distance under the guidance of the front guide duct 610, thereby realizing rapid cooling and regulation of the indoor environment.

[0066] In the scattered wind mode, Figure 7 and Figure 8 As shown, the rotating shaft 430 is in the second rotation position, and the air guide plate 500 closes the lower air outlet 120. The front baffle 410 avoids the first wind dispersing structure 230, the bottom baffle 420 opens the connecting port 310, the air guide plate 500 closes the lower air outlet 120, and the airflow in the main air duct 110 enters the wind dispersing duct 300 through the connecting port 310, and then is blown forward after being dispersed by the first wind dispersing structure 230, thereby forming a breeze feeling area with a slow airflow velocity and low noise in front of the indoor unit.

[0067] Specifically, the air guide plate 500 may be a closed plate, such as Fig. 9 and Fig.11 As shown, a second wind dispersing structure 510 may also be provided, and the setting of the second wind dispersing structure 510 has little effect on the flatness of the guide surface on the air guide plate 500. When the air guide plate 500 is opened, it can ensure the normal guidance of the air from the lower air outlet 120 by the upper guide surface. In the above-mentioned quick adjustment mode, wind shielding quick adjustment mode and cooling air guide mode, the air guide plate 500 is in an open state, and the air guide plate 500 is a closed plate or is provided with a second wind dispersing structure 510, which has little effect on its guide effect.

[0068] Accordingly, when the air guide plate 500 is in a closed state, compared with the air guide plate 500 in the form of a closed plate, the air guide plate 500 provided with the second air dispersing structure 510 can discharge air through the second air dispersing structure 510 and disperse it, and the air discharge effects of the two are completely different. For example, in the above-mentioned air dispersing mode, the air guide plate 500 closes the lower air outlet 120. According to the state of the air guide plate 500, it can be specifically divided into an upper air dispersing mode and a full air dispersing mode. Among them, when the air guide plate 500 is a closed plate, such as Figure 7 and Figure 8 As shown, it is an upper wind dispersion mode, the airflow of the main air duct 110 can only be dispersed outward through the wind dispersion duct 300 and the first wind dispersion structure 230, and only the upper area wind dispersion of the first wind dispersion structure 230 is obtained; when the wind guide plate 500 is provided with a second wind dispersion structure 510, as shown Fig. 9 and Fig.10 As shown, this is a full wind dispersion mode, in which a part of the airflow of the main air duct 110 is dispersed outward through the wind dispersion duct 300 and the first wind dispersion structure 230, and the other part of the airflow is dispersed outward through the second wind dispersion structure 510, so that the upper area wind dispersion corresponding to the first wind dispersion structure 230 and the lower area wind dispersion corresponding to the second wind dispersion area can be obtained at the same time, and a larger breeze feeling area is obtained in front of and below the indoor unit.

[0069] When the air guide plate 500 is provided with the second air dispersion structure 510, the indoor unit has a downward air dispersion mode in addition to the above-mentioned full air dispersion mode, such as Fig.11 and Fig.12As shown, in the lower wind dispersing mode, the rotating shaft 430 is located at the first rotation position, and the wind guide plate 500 closes the lower air outlet 120. The front baffle 410 covers and closes the first wind dispersing structure 230, and the bottom baffle 420 closes the connecting port 310. The airflow of the main air duct 110 is all dispersed by the second wind dispersing structure 510 and blown forward and downward, thereby forming a breeze feeling area with a soothing wind feeling at the front and lower part of the indoor unit; wherein, under the double blocking effect of the front baffle 410 and the bottom baffle 420, the vortex and noise formed by the airflow of the main air duct 110 entering the wind dispersing duct 300 can be effectively reduced, and at the same time, the airflow of the indoor environment entering through the first wind dispersing structure 230 and the wind dispersing duct 300 and contacting with the cold airflow of the main air duct 110 to form condensation liquid dripping downward can be reduced, thereby correspondingly improving the temperature regulation effect and use comfort of the indoor unit.

[0070] In addition to the above-mentioned fixed connection to realize linkage connection, the front baffle plate 410 and the bottom baffle plate 420 of the baffle 400 can also adopt the following forms in this embodiment: Fig.17 As shown, the front baffle 410 is rotatably sleeved on the rotating shaft 430, the bottom baffle 420 is fixedly connected to the rotating shaft 430, and the first magnetic attraction member 710 capable of magnetic attraction is provided on the sides facing each other of the front baffle 410 and the bottom baffle 420, and the second magnetic attraction member 720 capable of magnetic attraction is provided on the sides facing each other of the front baffle 410 and the front end plate. Fig.17 The solid line of the middle baffle 400 shows that the first rotating driving member drives the rotating shaft 430 to rotate to the first rotation position, and the bottom baffle 420 fixed to the rotating shaft 430 rotates to close the connecting port 310, that is, the first rotating driving member can limit the bottom baffle 420 to the position of closing the connecting port 310 through the rotating shaft 430; the front baffle 410 can rotate relative to the rotating shaft 430, and the front baffle 410 and the front end plate are magnetically attracted by the two second magnetic attracting members 720, so that the front baffle 410 is limited to the position of covering the first wind dispersing structure 230. When the first wind dispersing structure 230 needs to be opened to disperse the air, such as Fig.17 As shown by the middle dotted line, the first rotating driving member drives the rotating shaft 430 to drive the bottom baffle 420 to first rotate outward and approach the front baffle 410, until the two first magnetic suction members 710 magnetically attract the front baffle 410 and the bottom baffle 420 together, and the gap between the lower edge of the front end plate and the rotating shaft 430 allows the bottom baffle 420 to pass through. The first rotating driving member continues to drive the rotating shaft 430 to rotate, and the bottom baffle 420 drives the front baffle 410 to overcome the magnetic attraction of the two second magnetic suction members 720 and rotate outward synchronously until it reaches the second rotation position, thereby achieving the front baffle 410 avoiding the first wind dispersion structure 230 and the bottom baffle 420 opening the connecting port 310.

[0071] Similarly, when it is necessary to cover the first wind dissipation structure 230 and the connecting port 310 again, the first rotating driving member can use the driving shaft 430 to rotate toward the front end plate until the front baffle 410 abuts against the front end plate, and the second magnetic suction members 720 of the two magnetically limit the front baffle 410; the first rotating driving member continues to drive the shaft 430 to rotate, and the bottom baffle 420 overcomes the magnetic suction force of the two first magnetic suction members 710 and rotates inward until the shaft 430 reaches the first rotation position, and the bottom baffle 420 closes the connecting port 310.

[0072] It can be seen that when the baffle 400 adopts the above-mentioned form to realize the linkage connection, when the front baffle 410 rotates outward to open the first wind dispersion structure 230, the short baffle will inevitably be located outside the wind dispersion duct 300 along with the front baffle 410, and there is no shielding effect on the connecting port 310, thereby ensuring the ventilation area of ​​the connecting port 310 and the air output of the first wind dispersion structure 230 in the wind dispersion mode, and preventing the front baffle 410 from rotating outward at a small angle, resulting in a large shielding area of ​​the connecting port 310 by the bottom baffle 420, thereby reducing the restriction on the rotation angle of the front baffle 410 accordingly.

[0073] Of course, as required, the first rotation driving member can drive the front baffle 410 to rotate outward to any position, and is not limited to the second rotation position mentioned above.

[0074] In addition to the above two forms, the blocking member 400 can also be in the following forms in this embodiment: Fig.18 As shown, the front baffle 410 is fixed to the rotating shaft 430, the bottom baffle 420 is rotatably sleeved on the rotating shaft 430, and the front end plate and the bottom baffle 420 are both provided with a third magnetic member 730 on the opposite side. The two third magnetic members 730 can be magnetically attracted and at least one of them is an electromagnet; an elastic reset member 740 is connected between the front baffle 410 and the bottom baffle 420, and the housing 10 is provided with an angle detector for detecting the rotation angle of the rotating shaft 430. The angle detector and the electromagnet are both connected to the controller of the indoor unit. When the first wind dispersing structure 230 is not needed to be opened for wind dispersing, as shown in FIG. Fig.18 As shown by the solid line of the middle baffle 400, the first rotating drive member drives the rotating shaft 430 to be in the first rotation position, and the front baffle 410 fixedly connected to the rotating shaft 430 covers the front side of the first wind dispersing structure 230 accordingly; the bottom baffle 420 can rotate relative to the rotating shaft 430, and the angle detector feeds back the angle information of the rotating shaft 430 in the first rotation position to the controller, and the controller controls the closing of the electromagnet accordingly. If the two third magnetic suction members 730 do not have a magnetic suction effect, they will be stabilized at the position of the closed connecting port 310 under the connection of the elastic reset member 740, thereby realizing the covering of the first wind dispersing structure 230 by the front baffle 410 and the closing of the connecting port 310 by the bottom baffle 420. When it is necessary to open the first wind dispersing structure 230 to disperse air outward, as shown in FIG. Fig.18As shown by the dotted line of the middle baffle 400, the first rotating drive member drives the front baffle 410 to rotate outward, and the angle detector detects the angle change of the rotating shaft 430 and feeds back the change information to the controller. The controller controls the electromagnet to open accordingly, and a magnetic attraction force is generated between the two third magnetic members 730, and the magnetic attraction force is greater than the elastic force of the elastic reset member 740, so that the two third magnetic members 730 are magnetically attracted together, thereby driving the bottom baffle 420 to rotate and be magnetically attracted to the front end plate, thereby no longer closing the connecting port 310; the front baffle 410 can be rotated outward to the second rotation position and any other position driven by the first rotating drive member.

[0075] Similarly, when it is necessary to cover the first wind dissipation structure 230 and the connecting port 310 again, the first rotating drive member drives the rotating shaft 430 to rotate, the angle detector detects the change in the rotation angle of the rotating shaft 430 and feeds back the rotation information to the controller, and the controller accordingly turns off the electromagnet, the bottom baffle 420 is no longer magnetically attracted to the front end plate, and the front baffle 410 rotates toward the front end plate under the drive of the first rotating drive member, and the elastic reset member 740 drives the bottom baffle 420 to rotate inward synchronously with the front baffle 410 until the front baffle 410 abuts against the front end plate, and the rotating shaft 430 reaches the first rotation position, at which time the bottom baffle 420 also reaches the position of closing the connecting port 310.

[0076] It can be seen that when the baffle 400 adopts the above-mentioned form to realize the linkage connection, when the front baffle 410 rotates outward to open the first wind dispersion structure 230, the short baffle can be magnetically attracted to the front end plate in an approximately vertical state and no longer blocks the connecting port 310, thereby ensuring the ventilation area of ​​the connecting port 310 and the air output of the first wind dispersion structure 230 in the wind dispersion mode, and preventing the front baffle 410 from rotating outward at a small angle, resulting in a large blocking area of ​​the connecting port 310 by the bottom baffle 420, thereby reducing the restriction on the rotation angle of the front baffle 410 accordingly.

[0077] In this embodiment, Figure 13-Figure 16 As shown, the front baffle plate 410 can specifically be a closed plate, or can be provided with a third wind dispersing structure 411. When the third wind dispersing structure 411 is provided, in order to ensure that the front baffle plate 410 effectively covers and closes the first wind dispersing structure 230, when the rotating shaft 430 is located in the first rotation position, the projection of the first wind dispersing structure 230 toward the front baffle plate 410 is different from the area where the third wind dispersing structure 411 is located, that is, the area where the front baffle plate 410 is provided with the third wind dispersing structure 411 is the wind dispersing area, and the remaining area is the covering area. When the rotating shaft 430 is rotated to the first rotation position, the covering area can completely cover the first wind dispersing structure 230 to achieve covering and closing it.

[0078] When the front baffle 410 is provided with the third air dispersion structure 411 and the baffle 400 adopts the latter two linkage forms, the indoor unit additionally has a double air dispersion mode. In the double air dispersion mode, Fig.15 and Fig.16 As shown, the rotation angle range between the front baffle plate 410 and the front end plate is [20°, 45°], and the air guide plate 500 closes the lower air outlet 120 . The front baffle plate 410, which is at an angle of 20° to 45° with the lower wind dispersion area 220, no longer closes the first wind dispersion structure 230, can block most of the area of ​​the first wind dispersion structure 230 and has a small distance from the first wind dispersion structure 230. A part or all of the airflow in the main air duct 110 flows into the wind dispersion duct 300 through the connecting port 310. Most of the primary wind dispersed and blown out by the first wind dispersion structure 230 blows forward to the front baffle plate 410, and is dispersed again by the third wind dispersion structure 411 thereon to become secondary wind and blown forward, thereby ensuring the secondary dispersion of the primary wind by the third wind dispersion structure 411, and correspondingly forming a windless area with fine and dispersed airflow in front of the indoor unit of the air conditioner; at the same time, a small part of the airflow reaching the front baffle plate 410 can flow forward and upward under the guiding effect of the front baffle plate 410, thereby reaching a farther distance in front of the indoor unit of the air conditioner, and correspondingly increasing the range of the windless area.

[0079] Optionally, in this embodiment, if Figure 1 and Figure 3 As shown, the left end plate and the right end plate 130 of the housing 10 are provided with auxiliary wind dispersion structures 131 in the areas corresponding to the wind dispersion duct 300. The auxiliary wind dispersion structures 131 are provided at the left and right ends of the wind dispersion duct 300. In the wind dispersion mode, the airflow of the wind dispersion duct 300 is not only dispersed and blown out by the first wind dispersion structure 230 at the front side, but also dispersed and blown out outwards through the auxiliary wind dispersion structures 131 at the left and right ends thereof, thereby increasing the wind dispersion area of ​​the wind dispersion duct 300 and improving the wind dispersion effect and temperature regulation effect in the wind dispersion mode.

[0080] Optionally, the first wind dispersion structure 230, the second wind dispersion structure 510, the third wind dispersion structure 411 and the auxiliary wind dispersion structure 131 can adopt a plurality of dispersedly arranged wind dispersion holes, or a mounting hole can be set on the corresponding plate body, and an impeller can be rotatably connected in the mounting hole, 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.

[0081] Specifically, in this embodiment, when the first wind dispersing structure 230 is in the form of wind dispersing holes, Fig.14As shown, the wind dispersion hole can be an offset hole 231, which 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 surface, and the projections of the first hole segment 231a and the second hole segment 231b onto the projection surface partially overlap. The first wind dispersion structure 230 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 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.

[0082] Of course, when the second wind dispersing structure 510, the third wind dispersing structure 411 and the auxiliary wind dispersing structure 131 are in the form of wind dispersing holes, the above-mentioned staggered holes 231 may also be used.

[0083] 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. On the one hand, 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 between 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 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, which affects the temperature regulation effect of the air conditioner. On the other hand, the front baffle 410 is hinged to the lower edge of the lower wind dispersion area 220 through the rotating shaft 430. Especially for wall-mounted air conditioners, the front baffle 410 rotates up and down instead of left and right, and the front space of the upper closed area 210 or the front space of the lower air outlet 120 can be used to realize the rotation movement, and will not occupy the left and right side spaces of the air conditioner indoor unit, thereby reducing the space occupation requirement of the air conditioner indoor unit; at the same time, the front baffle 410 that rotates up and down can also guide the air outlet of the first wind dispersion structure 230 and cooperate with the air guide plate 500 to guide the air outlet of the lower air outlet 120, so as to improve the adjustability of the air outlet direction of the air conditioner indoor unit.

[0084] Optionally, in this embodiment, if Figure 1-Figure 4 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 receiving groove 240 matches the front baffle 410. When the air conditioner is turned off, the front baffle 410 can be inserted into the receiving groove 240 when it rotates to cover the first wind dispersing structure 230, which can not only ensure the airtightness 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 of the air conditioner when the air conditioner is turned off.

[0085] Specifically, in this embodiment, 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.
