[0002] Air conditioners are widely used for temperature regulation in indoor environments. When operating, existing air conditioners generally blow air outward through the lower air outlet of their main air duct. The lower air outlet is located at the bottom of the air conditioner shell and the air outlet is a direct blow with a large airflow intensity, resulting in poor comfort in the direct blow area of ​​the lower air outlet. Based on this, some air conditioners are equipped with a dispersing structure that can disperse the air outlet. However, the dispersing structure and its air duct are easily blocked by dust deposition, resulting in that they cannot be used normally, and the air outlet direction of the air conditioner is poorly adjustable.

DETAILED DESCRIPTION

[0043] 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.

[0044] This embodiment provides an air conditioner indoor unit, such as Figure 1-Figure 4 As shown, it includes a shell 10, the front end plate of the shell 10 is provided with a first wind dispersion structure 221, a main air duct 110 and an air dispersion duct 310 are provided in the shell 10, and the main air duct 110 is connected to the first wind dispersion structure 221 through the wind dispersion duct 310; the front side of the front end plate is hinged with a front baffle 400 for covering or avoiding the first wind dispersion structure 221, and the shell 10 is provided with a wind guide plate 500 for closing or opening the lower air outlet 111 of the main air duct 110, wherein, along the height direction of the shell 10, the lower air outlet 111 is located at the lower side of the first wind dispersion structure 221.

[0045] This embodiment also provides an air conditioner, including an air conditioner outdoor unit and the above-mentioned air conditioner indoor unit, and the air conditioner indoor unit and the air conditioner outdoor unit are connected through a refrigerant pipe to form a refrigerant circulation system.

[0046] 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 310 for conveying air to the outside, a first scattered air structure 221 located at the front end and used to disperse the airflow passing through, a front baffle 400 for adjusting the air flow rate and air outlet direction of the first scattered air structure 221, and an air guide plate 500 for adjusting the air flow rate and air outlet direction of the main air duct 110; wherein the air conditioner includes an air conditioner outdoor unit for heat exchange with the outdoor environment and the above-mentioned air conditioner indoor unit for adjusting the temperature of the indoor environment.

[0047] 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:

[0048] When the user needs to quickly adjust the indoor temperature, the air guide plate 500 can be opened to put the air conditioner into the quick adjustment mode. At this time, the airflow blown out of the main air duct 110 is almost completely blown directly outward through the lower air outlet 111 in the open state, thereby achieving rapid adjustment of the indoor ambient temperature; wherein, the angle between the air guide plate 500 and the lower air outlet 111 can be adjusted, thereby adjusting the guide direction of the air flow by 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, whose panel surface is in a continuously closed state, can keep covering the first wind dispersion structure 221 to cut off the connection between the indoor environment and the wind dispersion duct 310 through the first wind dispersion structure 221, thereby reducing the indoor airflow entering the wind dispersion duct 310 and the cold air flow of the main air duct 110 to form condensation when it comes into contact with the cold air flow of the main air duct 110, resulting in the occurrence of condensation and water blowing at the lower air outlet 111, and reducing the air volume loss caused by the air flow branch of the main air duct 110 flowing into the wind dispersion duct 310, thereby correspondingly improving the temperature regulation effect of the air conditioner indoor unit and the air conditioner and the user comfort. Alternatively, the front baffle 400 can also be opened and its outward rotation angle can be adjusted so that the front baffle 400 and the air guide plate 500 cooperate with each other on the upper and lower sides of the lower air outlet 111 to guide the airflow blown out of the lower air outlet 111, thereby improving the adjustability of the air conditioner indoor unit to the air outlet direction. Among them, when the first wind dispersion structure 221 and the lower air outlet 111 are opened at the same time, due to the large resistance of the wind dispersion duct 310 and the first wind dispersion structure 221, the airflow of the main air duct 110 is still blown out through the lower air outlet 111 to ensure the air outlet flow of the air conditioner indoor unit; at the same time, the front baffle 400 is blocked above the lower air outlet 111, and can also reduce the airflow backflow to the lower air outlet 111 on the top of the shell 10, thereby reducing the air volume loss and ensuring the air conditioner to quickly adjust the indoor ambient temperature.

[0049] When the user requires a more relaxed airflow outward from the indoor unit of the air conditioner, the user can close the air guide plate 500 to seal the lower air outlet 111, and at the same time rotate the front baffle 400 to form a preset angle with the front end plate, and the air conditioner enters the wind dispersion mode. Since the lower air outlet 111 is closed by the air guide plate 500, the airflow in the main air duct 110 can flow into the wind dispersion duct 310 through the connecting port 320 between the wind dispersion duct 310 and the main air duct 110, and then be dispersed by the first wind dispersion structure 221 and blown forward to form a breeze feeling area with a lower air flow speed and a more relaxed breeze.

[0050] Among them, when the turning angle between the front baffle plate 400 and the front end plate is greater than 40°, the shielding effect of the front baffle plate 400 on the front end plate is weak, and the first wind dispersion structure 221 can discharge air normally, which indicates that the front baffle plate 400 has avoided the first wind dispersion structure 221. The turning angle of the front baffle plate 400 can be adjusted within the range of the turning angle greater than 40°, and the airflow dispersed and blown out by the first wind dispersion structure 221 can flow under the guiding effect of the front baffle plate 400, thereby adjusting the flow direction of the airflow blown out by the first wind dispersion structure 221.

[0051] 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 or a scattered wind mode with a more gentle air flow. In the fast adjustment mode, the angle between the air guide plate 500 and the lower air outlet 111 can be adjusted to adjust the air flow direction of the lower air outlet 111. At the same time, the front baffle plate 400 can be adjusted to cover the first scattered wind structure 221 to increase the air volume of the lower air outlet 111 and ensure the air quality. The air conditioner can quickly adjust the temperature of the indoor environment, reduce the phenomenon of condensation and water blowing at the lower air outlet 111, or adjust the outward rotation angle of the front baffle 400, so that the front baffle 400 and the air guide plate 500 can guide the air flow of the lower air outlet 111 more effectively at the upper and lower positions of the lower air outlet 111 on the basis of ensuring the air volume of the lower air outlet 111; wherein, in the scattered wind mode, the rotation angle of the front baffle 400 can be adjusted to adjust the air flow direction of the first scattered wind structure 221. 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.

[0052] When the air conditioner is not in use, the front baffle 400 can be adjusted to rotate to a position covering the first wind dispersion structure 221, and the wind guide plate 500 can be adjusted to move to a position closing the lower air outlet 111, thereby reducing the occurrence of pollution and blockage caused by external dust entering the wind dispersion duct 310 and the main air duct 110 through the first wind dispersion structure 221 and the lower air outlet 111 and depositing therein. At the same time, the front baffle 400 blocks the front side of the first wind dispersion structure 221, which can simultaneously reduce the deposition and blockage of the first wind dispersion structure 221 caused by dust, thereby ensuring the normal operation of the first wind dispersion structure 221, the air conditioner indoor unit and the air conditioner, and reducing the occurrence of secondary pollution to the indoor environment caused by the dust deposited in the first wind dispersion structure 221, the wind dispersion duct 310 and the main air duct 110 when the air conditioner is turned on.

[0053] Among them, the front baffle 400 is hinged to the front side of the front end plate. In addition to cooperating with the air guide plate 500 to guide the airflow blown out of the lower air outlet 111 in the above-mentioned quick adjustment mode, and blocking the first wind dispersion structure 221 and the wind dispersion duct 310 from dust and blockage in the shutdown state, the front baffle 400 can also be disassembled and maintained externally, and the disassembly and assembly are convenient. The setting and rotation of the front baffle 400 does not occupy the internal space of the shell 10, thereby ensuring the arrangement of the wind dispersion duct 310 and the main air duct 110, and reducing the overall volume of the air conditioner indoor unit.

[0054] Optionally, the housing 10 may be provided with a first rotating driving member and a second rotating driving member, wherein the driving end of the first rotating driving member is connected to the front baffle 400, and is used to drive the front baffle 400 to rotate around the hinge; the air guide plate 500 is hinged to the rear area of ​​the lower air outlet 111, and the driving end of the second rotating driving member is connected to the air guide plate 500, and is used to drive the air guide plate 500 to rotate relative to the lower air outlet 111. Specifically, both the first rotating driving member and the second rotating driving member may be motors.

[0055] Specifically, in this embodiment, Figure 2 and Figure 3 As shown, the front end plate of the housing 10 includes an upper closed area 210 and a lower wind dispersion area 220 from top to bottom, and the first wind dispersion structure 221 is located in the lower wind dispersion area 220; the front baffle 400 is hinged to the upper edge or the lower edge of 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 221 that can be ventilated. The first wind dispersion structure 221 and the wind dispersion duct 310 therein are close to the main air duct 110 and far away from the air inlet at the top of the housing 10. The wind dispersion duct 310 has a higher connectivity with the main air duct 110 and a smaller flow resistance, 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 221 is easy to flow back upward to the air inlet due to the small distance between the first wind dispersion structure 221 and the air inlet at the top of the housing 10, affecting the temperature regulation effect of the air conditioner. On the other hand, the front baffle 400 is hinged to the upper edge or the lower edge of the lower wind dispersion area 220. The front baffle 400 rotates up and down instead of left and right. The front space in front of the upper closed area 210 or the front space in front of the lower air outlet 111 can be used to achieve rotational movement, and will not occupy the left and right sides 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 400 that rotates up and down can also guide the air outlet of the first wind dispersion structure 221 and cooperate with the air guide plate 500 to guide the air outlet of the lower air outlet 111, so as to improve the adjustability of the air outlet direction of the air conditioner indoor unit.

[0056] Preferably, if Figure 2As shown, the front end surface of the lower wind dispersing area 220 is concave compared to the upper closed area 210 to form a receiving groove 222, and the receiving groove 222 matches the front baffle 400; when the air conditioner is in the off state, the front baffle 400 can be embedded in the receiving groove 222 when it rotates to cover the first wind dispersing structure 221, which not only ensures the air tightness of the covering of the first wind dispersing structure 221, but also enables the front baffle 400 and the front end plate to be approximately combined into a plate body with a flat front end surface, thereby improving the overall structural neatness and appearance of the air conditioner when the air conditioner is in the off state.

[0057] Specifically, according to the covering condition of the first wind dispersing structure 221 by the front baffle 400 and the condition that the wind guide plate 500 opens the lower air outlet 111, the indoor unit of the air conditioner specifically has a waterproof quick adjustment mode and a wind dispersing mode, wherein:

[0058] In the waterproof quick adjustment mode, the front baffle 400 covers the first wind dispersion structure 221, and the wind guide plate 500 opens the lower air outlet 111; the front baffle 400 blocks the connection between the indoor environment and the wind dispersion duct 310, thereby reducing the indoor air flow entering the wind dispersion duct 310 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 111, and reducing the air volume loss caused by the air flow branch of the main air duct 110 flowing into the wind dispersion duct 310, thereby correspondingly improving the temperature regulation effect of the air conditioner indoor unit and the air conditioner and the user's comfort.

[0059] In the wind dispersion mode, the front baffle 400 avoids the first wind dispersion structure 221, and the wind guide plate 500 closes the lower air outlet 111. The front baffle 400 rotates to a position where the first wind dispersion structure 221 is less blocked. Preferably, the front baffle 400 rotates to a position where the first wind dispersion structure 221 is not blocked at all in the front-to-back direction. The airflow of the main air duct 110 is dispersed by the wind dispersion duct 310 and the first wind dispersion structure 221 and blown forward, thereby forming a relatively soothing breeze feeling area with a low airflow velocity in front of the indoor air conditioner; or, the rotation angle of the front baffle 400 can be adjusted within the range of [40°, 60°], and the airflow dispersed and blown out by the first wind dispersion structure 221 can flow under the guiding effect of the front baffle 400, thereby adjusting the flow direction of the airflow blown out by the first wind dispersion structure 221.

[0060] When the air guide plate 500 is a closed plate, the above-mentioned air dispersion mode is specifically an upper air dispersion mode, such as Fig.17 and Fig.18 As shown, the airflow of the main air duct 110 is blown out only after being dispersed through the dispersed air duct 310 and the first dispersed air structure 221, forming a breeze feeling area in front of the indoor unit.

[0061] Optionally, in this embodiment, if Figure 1 and Figure 2As shown, the air guide plate 500 is provided with a second air dispersing structure 510. The second air dispersing structure 510 on the air guide plate 500 can disperse the airflow passing through it, wherein, since the lower air outlet 111 is located at the bottom of the housing 10, when the air conditioner is not in use, the air guide plate 500 that closes the lower air outlet 111 is also located at the bottom of the housing 10, and the probability of dust being deposited on the air guide plate 500 and the second air dispersing structure 510 is small, which can ensure the cleanliness and smoothness of the second air dispersing structure 510, thereby ensuring its air dispersing function. When the air conditioner is used, in the fast adjustment mode, the air guide plate 500 is opened, and the second wind dispersion structure 510 has little effect on the flow conductivity of the guide surface of the air guide plate 500, so that the air guide plate 500 can normally guide the air out of the lower air outlet 111; in the wind dispersion mode, the front baffle 400 can avoid the first wind dispersion structure 221 as described above, and the air guide plate 500 can close the lower air outlet 111. At this time, the first wind dispersion structure 221 located on the front end plate and the second wind dispersion structure 510 located on the air guide plate 500 can both discharge air and disperse the outlet air flow, so that the indoor unit of the air conditioner has the first wind dispersion structure 221. The air dispersion structure 221 is used to disperse the wind forward and the second air dispersion structure 510 is used to disperse the wind forward and downward, thereby increasing the air dispersion area and air outlet range of the indoor unit of the air conditioner and improving the air dispersion effect of the indoor unit of the air conditioner. In addition, the front baffle 400 and the air guide plate 500 can also be closed, so that the first air dispersion structure 221 located on the front end plate is blocked by the front baffle 400, and the lower air outlet 111 is closed by the air guide plate 5000. The airflow in the main air duct 110 can be blown out through the second air dispersion structure 510 on the air guide plate 500 and the blowing process is dispersed, so that the indoor unit of the air conditioner only has downward and forward air dispersion.

[0062] When the wind guide plate 500 is provided with the second wind dispersing structure 510, the wind dispersing mode is specifically a full wind dispersing mode, and the wind dispersing mode may include a lower wind dispersing mode in addition to the full wind dispersing mode, wherein:

[0063] In the full wind dispersing mode, the front baffle 400 avoids the first wind dispersing structure 221, and preferably, the front baffle 400 extends forward; the wind guide plate 500 closes the lower air outlet 111. The first wind dispersing structure 221 located on the front end plate and the second wind dispersing structure 510 located on the wind guide plate 500 can both discharge air and disperse the airflow, and the front baffle 400 does not block the first wind dispersing structure 221 and the second wind dispersing structure 510, so that the indoor unit of the air conditioner has the wind dispersing outlet forward through the first wind dispersing structure 221 and the wind dispersing outlet forward and downward through the second wind dispersing structure 510, thereby increasing the wind dispersing outlet area and air dispersing range of the indoor unit of the air conditioner, and improving the wind dispersing effect and temperature regulation effect of the indoor unit of the air conditioner.

[0064] Specifically, Figure 3 and Figure 4 As shown, when the front baffle 400 is hinged to the lower edge of the lower wind dispersion area 220, the full wind dispersion mode is the first full wind dispersion mode; Fig.13 and Fig.14 As shown, when the front baffle 400 is hinged to the upper edge of the lower wind dispersion area 220, the full wind dispersion mode is the second full wind dispersion mode. In the second full wind dispersion mode, when the front baffle 400 extends horizontally forward, in addition to cooperating with the air guide plate 500 to guide the air inlet, the front baffle 400 can be blocked on the upper side of the first wind dispersion structure 221 to reduce the occurrence of upward reflux of the scattered air blown out through the second wind dispersion structure 510 and the first wind dispersion structure 221 under the guidance of the air inlet at the top of the shell 10, thereby ensuring the wind dispersion and temperature regulation effects in this mode.

[0065] Specifically, in the downward wind mode, Figure 1 and Figure 2 As shown, the front baffle 400 covers the first wind dispersing structure 221 at the front side, and the wind guide plate 500 closes the lower air outlet 111. When the air conditioner is running, the airflow in the main air duct 110 can be blown out through the second wind dispersing structure 510 on the wind guide plate 500 and the blowing process is dispersed, so that the indoor unit of the air conditioner has downward and forward wind dispersing.

[0066] When the wind guide plate 500 is provided with a second wind dispersion structure 510 and the front baffle plate 400 is hinged to the lower edge of the lower wind dispersion area 220, the quick adjustment mode may include a wind guide quick adjustment mode and a mixed wind mode in addition to the above-mentioned waterproof quick adjustment mode.

[0067] In the air guide fast adjustment mode, the front baffle 400 avoids the first wind dispersing structure 221, the air guide plate 500 opens the lower air outlet 111, and the front baffle 400 and the air guide plate 500 cooperate at the upper and lower sides of the lower air outlet 111 to guide the air to the lower air outlet 111; specifically, the angle range between the front baffle 400 and the front end plate is [40°, 180°]. The front baffle 400 and the air guide plate 500 cooperate at the upper and lower sides of the lower air outlet 111 to guide the airflow blown out of the lower air outlet 111, thereby improving the adjustability of the air conditioner indoor unit to the air outlet direction; at the same time, the front baffle 400 blocks the upper part of the lower air outlet 111, which can also reduce the airflow backflow to the lower air outlet 111 at the top of the shell 10, thereby reducing the air volume loss and ensuring the air conditioner to quickly adjust the indoor ambient temperature.

[0068] In mixed air mode, Figure 5 and Figure 6As shown, the front baffle 400 avoids the first wind dispersing structure 221 and extends downward, the wind guide plate 500 opens the lower air outlet 111 and extends forward, and the front baffle 400 and the wind guide plate 500 overlap each other; the wind guide plate 500 is rotated downward to open a certain angle, and the front baffle 400 is rotated downward to open, until the bottom end of the front baffle 400 overlaps the upper guide surface of the wind guide plate 500, or the front end of the wind guide plate 500 overlaps the rear end surface of the front baffle 400, or the front end of the wind guide plate 500 overlaps the bottom end of the front baffle 400, then the first wind dispersing structure 221 located at the front end plate is in an open state, the front baffle 400 and the wind guide plate 500 jointly block the lower air outlet 111 and the left and right ends of the two form end air outlets 630.

[0069] When the air conditioner is running, since the lower air outlet 111 of the main air duct 110 is blocked by the front baffle 400 and the wind guide plate 500 and there is a large wind resistance, a part of the airflow of the main air duct 110 flows into the wind dispersion duct 310 through the connecting port 320, and then is dispersed and blown forward through the first wind dispersion structure 221; when the wind guide plate 500 is provided with a second wind dispersion structure 510, the other part of the airflow is blown out through the lower air outlet 111 and is divided into two airflows, one of which is dispersed and blown downward through the second wind dispersion structure 510 of the wind guide plate 500, and the other airflow is blown to the left and right through the left and right end air outlets 630 as shown by the dotted arrows. The mixed wind mode can make the air conditioner indoor unit have the forward air dispersion outlet through the first air dispersion structure 221, the downward air dispersion outlet through the second air dispersion structure 510 and the rapid air discharge to the left and right through the two end air outlets 630, so that the area in front of the air conditioner indoor unit corresponding to the first air dispersion structure 221 and the area below the air conditioner indoor unit corresponding to the second air dispersion structure 510 are breeze feeling areas blown by the wind, the left and right side areas corresponding to the two end air outlets 630 of the air conditioner indoor unit are straight wind feeling areas with strong wind force, and the front lower area of ​​the air conditioner indoor unit corresponding to the front baffle 400 is approximately a windless feeling area, and the user can be located in the breeze feeling area, the straight wind feeling area or the windless feeling area as needed, with many choices and high usage experience. At the same time, the rapid air discharge of the end air outlets 630 can ensure the rapid temperature adjustment of the indoor environment by the air conditioner, thereby greatly improving the functionality of the air conditioner indoor unit and the air conditioner.

[0070] In the mixed wind mode, in addition to the above-mentioned second wind dissipation structure 510, the wind guide plate 500 can also be a closed plate body. When the air conditioner is running and discharging air, the difference from the above-mentioned air discharge is that the wind guide plate 500 cannot be ventilated, and the area in front of the air conditioner indoor unit corresponding to the wind guide plate 500 is approximately a windless zone, that is, the area in front of the air conditioner indoor unit corresponding to the first wind dissipation structure 221 is a breeze zone with scattered wind, the area corresponding to the air conditioner indoor unit and the front baffle 400 and the wind guide 500 is approximately a windless zone, and the left and right sides of the air conditioner indoor unit corresponding to the two end air outlets 630 are direct wind zones with relatively strong wind force, the breeze zone is smaller, and the windless zone is larger.

[0071] Specifically, according to the different matching angles of the front baffle 400 and the air guide plate 500, the air guide fast adjustment mode specifically includes a first cooling air guide mode and a heating air guide mode, wherein:

[0072] In the first cooling air flow mode, Figure 7 and Figure 8 As shown, the front baffle 400 avoids the first wind dispersing structure 221 and extends forward, and the air guide plate 500 opens the lower air outlet 111 and extends forward. The airflow of the main air duct 110 is blown out through the lower air outlet 111, and the front baffle 400 and the air guide plate 500 respectively block and guide the air above and below the lower air outlet 111 to form a front air guide duct 610 extending forward. The cold airflow blown out through the lower air outlet 111 can be blown forward for a longer distance under the guidance of the front air guide duct 610, thereby realizing rapid cooling and adjustment of the indoor environment.

[0073] In the heating and air conduction mode, Fig. 9 and Fig.10 As shown, the front baffle 400 avoids the first wind dissipation structure 221 and extends downward, and the air guide plate 500 opens the lower air outlet 111 and extends downward. The airflow of the main air duct 110 is mainly blown out through the lower air outlet 111, and the air guide plate 500 is hinged to the rear edge of the lower air outlet 111. The front baffle 400 and the air guide plate 500 are respectively provided at the front and rear sides of the lower air outlet 111 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 111 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.

[0074] In addition to being hinged to the lower edge of the lower wind dispersion area 220, the front baffle 400 may also be Figure 11-Figure 16 As shown, when the front baffle 400 can also be hinged to the upper edge of the lower wind dispersion area 220, the quick adjustment mode includes a second cooling air guide mode.

[0075] In the second cooling air flow mode, Fig.15 and Fig.16 As shown, the front baffle 400 avoids the first wind dispersing structure 221 and extends forward, and the wind guide plate 500 opens the lower air outlet 111 and extends forward. The airflow of the main air duct 110 is blown out through the lower air outlet 111, wherein the wind guide plate 500 guides the air forward at the lower side of the lower air outlet 111, so that the airflow blown out through the lower air outlet 111 can be blown forward to a longer distance under the guiding effect of the wind guide plate 500, thereby realizing rapid cooling and regulation of the indoor environment; at the same time, preferably, the front baffle 400 rotates to extend forward to a level that is approximately horizontal, so that the front baffle 400 can be blocked at the upper side of the first wind dispersing structure 221, thereby reducing the occurrence of the airflow blown out through the lower air outlet 111 flowing back upward under the guiding effect of the air inlet at the top of the shell 10, and correspondingly ensuring the cooling effect in this mode.

[0076] In this embodiment, Figure 1 and Figure 2 As 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 310. The first wind dispersing structure 221 is located in the corresponding area of ​​the panel 200 and the wind dispersing duct 310. 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 111 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 remaining area is vertically extended. The panel 200 is blocked at the front end surface of the inner shell 100. The upper closed area 210 of the panel 200 is arranged in affixed with the vertically extended area of ​​the front end plate of the inner shell 100, and the lower wind dispersing area 220 is arranged in affixed with the front end plate of the inner shell 100. The concave areas together form a scattered air duct 310, and a connecting port 320 is formed between the upper edge of the lower air outlet 111 and the panel 200 to connect the scattered air duct 310 and the main air duct 110; at the same time, the panel 200 serves as the front end plate of the entire shell 10, and a first scattered air structure 221 is set in the lower scattered air area 220 of the panel 200 to form the scattered air duct 310, so that the main air duct 110 and the scattered air duct 310 are enclosed by a simple shell 10 structure, which is convenient to process and low in cost.

[0077] Optionally, in this embodiment, if Figure 1 As shown, the left and right end plates 120 of the housing 10 and the areas corresponding to the wind dispersing duct 310 are provided with auxiliary wind dispersing structures 121. The auxiliary wind dispersing structures 121 are provided at the left and right ends of the wind dispersing duct 310. In the wind dispersing mode, the airflow of the wind dispersing duct 310 is dispersed and blown out through the auxiliary wind dispersing structures 121 at the left and right ends thereof in addition to being dispersed and blown out through the first wind dispersing structure 221 at the front side, thereby increasing the wind dispersing area of ​​the wind dispersing duct 310 and improving the wind dispersing effect and temperature regulation effect in the wind dispersing mode.

[0078] Optionally, the first wind dispersion structure 221, the second wind dispersion structure 510 and the auxiliary wind dispersion structure 121 can adopt a plurality of dispersedly arranged wind dispersion holes, or set mounting holes on the corresponding plate bodies, and rotatably connect impellers in the mounting holes, or other structures that can ventilate and disperse the airflow can be used; wherein, the shape, number and position of the wind dispersion holes in the drawings are shown as examples and are not intended to be actual limitations.

[0079] Specifically, in this embodiment, when the first wind dispersing structure 221 is in the form of wind dispersing holes, Figure 2As shown, the second air dispersion hole can be an offset hole 231. Specifically, the offset hole 231 includes a first hole segment 231a and a second hole segment 231b along the hole depth direction. The plane where one of the radial cross sections of the offset hole 231 is located is the projection plane. The projection of the first hole segment 231a onto the projection plane is the first projection, and the projection of the second hole segment 231b onto the projection plane is the second projection. The first projection partially overlaps with the second projection. The first wind dispersion structure 221 includes a plurality of dispersedly arranged offset holes 231, wherein a first hole segment 231a and a second hole segment 231b of the offset hole 231 have a part of their regions connected and another part of their regions offset, so that a first step surface 231c for blocking a local region of the first hole segment 231a, a connecting area 231d 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 310 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 turn, so that it is dispersed for the third time and then blown forward. The first wind dispersing structure 221 of this form can perform multiple dispersing processes on the airflow passing through, thereby improving the dispersing effect of the first wind dispersing structure 221 on the airflow, and the first wind dispersing structure 221 has a simple structure and a low processing cost.

[0080] Of course, when the second wind dispersing structure 510 and the auxiliary wind dispersing structure 121 are in the form of wind dispersing holes, the above-mentioned offset holes 231 may also be used.
