Description

Technical Field

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

[0002] Air conditioners are widely used for regulating the temperature of indoor environments. When operating, existing air conditioners generally blow air outward through the lower air outlet of the main air duct. The lower air outlet is located at the bottom of the air conditioner shell and the air is blown directly with a large airflow intensity, resulting in poor comfort in the direct blowing area of ​​the lower air outlet. Based on this, some air conditioners are equipped with a dispersion structure that can disperse the air. However, the dispersion mode of the air conditioner is relatively single and its dispersion structure is easily blocked by dust deposition, resulting in it being unable to be used normally. Utility Model Content

[0003] The purpose of the utility model includes providing an air conditioner indoor unit and an air conditioner to solve the technical problems that the existing air conditioner has a relatively single air dispersion mode and its air dispersion structure is easily blocked by dust deposition, resulting in the air conditioner being unable to be used normally.

[0004] In order to solve the above problems, the utility model provides an air conditioner indoor unit, comprising a shell, a front end plate of the shell is provided with a first air dispersion structure, a main air duct and an air dispersion duct are provided in the shell, and the main air duct is connected to the first air dispersion structure through the air dispersion duct;

[0005] A front baffle for shielding or avoiding the first wind dispersing structure is hingedly connected to the front side of the front end plate, and the front baffle is provided with a second wind dispersing structure. When the front baffle shields the front end surface of the first wind dispersing structure, the projection of the first wind dispersing structure toward the rear end surface of the front baffle completely falls on the plate body area of ​​the front baffle where the second wind dispersing structure is not provided. The shell is provided with an air guide plate for closing or opening the lower air outlet of the main air duct, and along the height direction of the shell, the lower air outlet is located at the lower side of the first wind dispersing structure.

[0006] In the indoor unit of the air conditioner provided by the utility model, the setting of the front baffle can make the indoor unit of the air conditioner enter a dispersion wind mode in which the air flow is dispersed only by the first dispersion wind structure by adjusting the size of the rotation angle of the front baffle relative to the front end plate. In this dispersion wind mode, the air flow velocity is small, relatively slow and has a high temperature regulation effect; or the indoor unit of the air conditioner enters a dispersion wind mode in which the air flow is dispersed by the first dispersion wind structure and the second dispersion wind structure in sequence.

[0007] In addition, the front baffle can also cooperate with the air guide plate to enter a fast adjustment mode that can quickly adjust the indoor ambient temperature. Among them, when the front baffle blocks the first wind dissipation structure, it can reduce the phenomenon of condensation and water blowing at the lower air outlet, so that the air conditioner indoor unit has a better air outlet waterproof effect; when the front baffle rotates to avoid the first wind dissipation structure, it can cooperate with the air guide plate on the upper and lower sides of the lower air outlet to guide the air outlet direction of the lower air outlet, thereby improving the controllability of the air outlet direction and temperature control adjustability of the air conditioner indoor unit. In addition, in the off state, the front baffle can be rotated to block the front end surface of the first wind dissipation structure, so that its covering area completely blocks the front port of the first wind dissipation structure, thereby reducing the blockage and secondary pollution caused by dust deposition in the first wind dissipation structure and the wind dissipation duct, and correspondingly ensuring the normal air outlet and clean air outlet of the first wind dissipation structure.

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 air conditioner indoor unit, such as Figure 1-Figure 4 As shown, it includes a shell 10, a front end plate of the shell 10 is provided with a first wind dispersion structure 230, a main air duct 110 and a wind dispersion duct 300 are provided in the shell 10, and the main air duct 110 is connected to the first wind dispersion structure 230 through the wind dispersion duct 300; a front baffle 400 for shielding or avoiding the first wind dispersion structure 230 is hinged on the front side of the front end plate, the front baffle 400 is provided with a second wind dispersion structure 410, and when the front baffle 400 shields the front end surface of the first wind dispersion structure 230, the projection of the rear end surface of the first wind dispersion structure 230 toward the front baffle 400 completely falls on the plate body area of ​​the front baffle 400 where the second wind dispersion structure 410 is not provided; the shell 10 is provided with an air guide plate 500 for closing or opening the lower air outlet 120 of the main air duct 110, and along the height direction of the shell 10, the lower air outlet 120 is located at the lower side of the first wind dispersion structure 230.

[0050] 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.

[0051] The present embodiment provides an air conditioner indoor unit and an air conditioner, wherein the air conditioner indoor unit includes a shell 10 with an air duct formed inside and serving as a mounting base, a main air duct 110 and a scattered air duct 300 for conveying air to the outside, a first scattered air structure 230 located at the front end and used to disperse the airflow passing through, a front baffle 400 for adjusting the air outlet state and air outlet direction of the first scattered air structure 230, and an air guide plate 500 for adjusting the air outlet flow rate and air outlet direction of the main air duct 110; wherein the air conditioner includes an air conditioner outdoor unit for heat exchange with the outdoor environment and the above-mentioned air conditioner indoor unit for adjusting the temperature of the indoor environment.

[0052] 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:

[0053] When the user needs a more relaxed airflow from the indoor unit of the air conditioner, the air guide plate 500 can be closed to close the lower air outlet 120, and the front baffle plate 400 can be rotated to form a preset angle with the front end plate, and the air conditioner enters the wind dispersion mode. Since the lower air outlet 120 is closed by the air guide plate 500, the airflow in the main air duct 110 can flow into the wind dispersion duct 300 through the connecting port 310 between the wind dispersion duct 300 and the main air duct 110, and then be dispersed by the first wind dispersion structure 230 to form a scattered wind that is blown forward. Among them, when the angle of rotation is large, the front baffle plate 400 only blocks a small local area of ​​the first wind dispersion structure 230. Or the first wind dispersion structure 230 is no longer blocked, then the primary wind dispersion is blown out directly forward, the air flow rate is small, it is relatively slow and has a higher temperature regulation effect; when the turning angle is small, the front baffle 400 still blocks the front side of most areas of the first wind dispersion structure 230 and the distance from the first wind dispersion structure 230 is small, then the primary wind dispersion is blown toward the front baffle 400 and is dispersed again by the second wind dispersion structure 410 thereon to form secondary wind dispersion that is blown forward, and the secondary wind dispersion that has been dispersed twice is more dispersed and dense, and the user can choose different wind dispersion modes according to their needs, thereby improving the functionality of the air conditioner indoor unit and improving the user experience.

[0054] In addition to the different wind dispersion modes mentioned above, when the user needs to quickly adjust the indoor temperature, the air guide plate 500 can be opened so that it no longer closes the lower air outlet 120, and the air conditioner enters the fast adjustment mode. At this time, the airflow blown out of the main air duct 110 is almost all blown directly outward through the lower air outlet 120 in the open state, thereby achieving rapid adjustment of the indoor ambient temperature; at the same time, the angle between the air guide plate 500 and the lower air outlet 120 can be adjusted, so as to adjust the guide direction of the air flow of the air guide plate 500 and the air outlet direction of the air conditioner indoor unit. In this fast adjustment mode, the front baffle plate 400 can be against the front end surface of the front end plate, and the covering area of ​​the front baffle plate 400 where the second wind dispersion structure 410 is not set can completely cover the first wind dispersion structure 230, so as to cut off the connection between the indoor environment and the wind dispersion duct 300 through the first wind dispersion structure 230, thereby reducing the indoor air flow entering the wind dispersion duct 300 and contacting the cold air flow of the main air duct 110 to form condensation, resulting in the occurrence of condensation and water blowing at the lower air outlet 120, and reducing the air volume loss caused by the air flow branch of the main air duct 110 flowing into the wind dispersion duct 300, thereby correspondingly improving the temperature adjustment effect of the air conditioner indoor unit and the air conditioner and the user's comfort. Moderate; alternatively, the front baffle 400 can be opened and its outward rotation angle relative to the front end plate can be adjusted, so that the front baffle 400 and the air guide plate 500 cooperate with each other at the upper and lower sides of the lower air outlet 120 to guide the airflow blown out of the lower air outlet 120, thereby improving the adjustability of the air outlet direction of the air conditioner indoor unit, and when the first wind dispersion structure 230 and the lower air outlet 120 are opened at the same time, due to the large resistance of the wind dispersion duct 300 and the first wind dispersion structure 230, the airflow of the main air duct 110 is mainly blown out through the lower air outlet 120 to ensure the air outlet flow of the air conditioner indoor unit, and correspondingly ensure the rapid adjustment of the indoor ambient temperature by the air conditioner.

[0055] When the air conditioner is not in use, the front baffle 400 can be adjusted to rotate and cover the front end surface of the first wind dispersion structure 230 so that its covering area completely covers the front port of the first wind dispersion structure 230, and the air guide plate 500 is adjusted to move to a position to close the lower air outlet 120, thereby reducing the deposition and blockage of the first wind dispersion structure 230 caused by dust, and at the same time 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, thereby ensuring that the first wind dispersion structure 230 can form an air outlet and the air outlet is clean, thereby 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.

[0056] Among them, the front baffle 400 is hinged to the front side of the front end plate. In addition to the above-mentioned cooperation with the air guide plate 500 to guide the airflow blown out of the lower air outlet 120, and the role of blocking dust and blocking the wind dispersion structure and the wind dispersion duct 300, the front baffle 400 can also be disassembled and maintained from the outside, 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 layout of the wind dispersion duct 300 and the main air duct 110, and reducing the overall volume of the air conditioner indoor unit.

[0057] In the indoor unit of the air conditioner provided in the present embodiment, the setting of the front baffle 400 can make the indoor unit of the air conditioner enter a dispersion wind mode in which the air flow is dispersed only by the first dispersion wind structure 230 by adjusting the size of the rotation angle of the front baffle 400 relative to the front end plate. In this dispersion wind mode, the air flow velocity is small, relatively slow and has a high temperature regulation effect; or the indoor unit of the air conditioner enters a dispersion wind mode in which the air flow is dispersed by the first dispersion wind structure 230 and the second dispersion wind structure 410 in sequence. In this dispersion wind mode, the air flow is more dispersed and dense, and the rotation angle of the front baffle 400 can be adjusted within a certain range to adjust the degree of dispersion of the air by the cooperation between the first dispersion wind structure 230 and the second dispersion wind structure 410, thereby improving the adjustment diversity of the dispersion wind mode.

[0058] In addition, the front baffle 400 can also cooperate with the air guide plate 500 to enter a fast adjustment mode that can quickly adjust the indoor ambient temperature. When the front baffle 400 blocks the first air dispersing structure 230, the phenomenon of condensation and water blowing at the lower air outlet can be reduced, so that the air conditioner has a better air outlet waterproof effect; when the front baffle 400 rotates to avoid the first air dispersing structure 230, it can cooperate with the air guide plate 500 on the upper and lower sides of the lower air outlet 120 to guide the air outlet direction of the lower air outlet 120, thereby improving the controllability of the air outlet direction and the temperature control adjustability of the air conditioner. In addition, in the off state, the front baffle 400 can rotate to block the front end surface of the first air dispersing structure 230, so that its covering area completely blocks the front port of the first air dispersing structure 230, thereby reducing the occurrence of blockage and secondary pollution caused by dust deposition in the first air dispersing structure 230 and the air dispersing duct 300, and correspondingly ensuring the normal air outlet and clean air outlet of the first air dispersing structure 230.

[0059] 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 120, 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 120. Specifically, both the first rotating driving member and the second rotating driving member may be motors.

[0060] Specifically, in this embodiment, the air conditioner indoor unit has a dual wind dissipation mode, such as Figure 3 , Figure 4 and Fig.14 As shown, in the double wind dispersion mode, the air guide plate 500 closes the lower air outlet 120, and the angle between the front baffle plate 400 and the area of ​​the front plate where the first wind dispersion structure 230 is set is in the range of 5° to 45°. In the double wind dispersion mode, the air guide plate 500 closes the lower air outlet 120, and the front baffle plate 400 rotates outward 5° to 45° relative to the front plate, and its covering area no longer closes the first wind dispersion structure 230, and the distance between the front baffle plate 400 and the first wind dispersion structure 230 is small and blocks the front side of most areas of the first wind dispersion structure 230; the airflow of the main air duct 110 enters the wind dispersion duct 300 through the connecting port 310, and is blown forward after being dispersed once by the first wind dispersion structure 230, and the primary dispersed air then blows to the front baffle plate 400 on the front side and is dispersed again by the second wind dispersion structure 410 thereof to become the secondary dispersed air and blown forward, thereby forming an air outlet area with a high degree of air flow dispersion and fineness in front of the air conditioner indoor unit on the basis of achieving indoor environmental temperature regulation.

[0061] In addition to the above-mentioned double diffused air mode, the indoor unit of the air conditioner also has a single diffused air mode, such as Figure 5 , Figure 6 and Fig.15 As shown, in the single-scattering wind mode, the air guide plate 500 closes the lower air outlet 120, and the angle between the front baffle plate 400 and the front end plate is 80° to 180°. In the single-scattering wind mode, the air guide plate 500 closes the lower air outlet 120, and the front baffle plate 400 rotates outward 80° to 180° relative to the front end plate to a position that almost completely avoids the front side of the first scattering wind structure 230; the airflow of the main air duct 110 enters the scattering wind duct 300 through the connecting port 310, and is blown forward after being dispersed once by the first scattering wind structure 230, thereby forming an air outlet area with a small air flow velocity and a slightly lower degree of dispersion in front of the air conditioner indoor unit, and the air outlet volume of the single-scattering wind mode is relatively high, which has a relatively high temperature regulation effect on the indoor environment.

[0062] In addition to the above-mentioned wind dispersion mode, the indoor unit also has a fast adjustment mode that can quickly adjust the indoor environment temperature, which can specifically include a waterproof fast adjustment mode. In the waterproof fast adjustment mode, the front baffle 400 blocks the first wind dispersion structure 230, and the wind guide plate 500 opens the lower air outlet 120. The front baffle 400 cuts off the connection between the indoor environment and the wind dispersion duct 300, thereby reducing the indoor airflow entering the wind dispersion duct 300 and contacting the cold airflow of the main air duct 110 to form condensation, resulting in the occurrence of condensation and water blowing at the lower air outlet 120, and reducing the air volume loss caused by the branch of the airflow of the main air duct 110 flowing into the wind dispersion duct 300, thereby correspondingly improving the temperature adjustment effect of the air conditioner indoor unit and the air conditioner and the user's comfort.

[0063] Optionally, in this embodiment, if Figure 1-Figure 4 As shown, the air inlet of the housing 10 is located at the top thereof, and the front end plate includes an upper closed area 210 and a lower air dispersion area 220 from top to bottom, and the first air dispersion structure 230 is located in the lower air dispersion area 220; the front baffle 400 is hinged to the upper edge or the lower edge of the lower air 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 air dispersion structure 230 that can be ventilated. The first air dispersion structure 230 and the air dispersion duct 300 therein are close to the main air duct 110 and far away from the air inlet at the top of the housing 10, so the air dispersion duct 300 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 air dispersion mode, and at the same time effectively reduce the occurrence of the situation that the air outlet of the first air dispersion structure 230 is easily backflowed upward to the air inlet due to the small distance between the first air dispersion structure 230 and the air inlet at the top of the housing 10, which affects 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. For a wall-mounted air conditioner, the front baffle 400 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 achieve rotational movement, without occupying 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 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.

[0064] Among them, when the front baffle 400 is hinged to the lower edge of the lower wind dispersion area 220, the quick adjustment mode can also include an air guide quick adjustment mode. In the air guide quick adjustment mode, the air guide plate 500 opens the lower air outlet 120, and the front baffle 400 avoids the first wind dispersion structure 230. The front baffle 400 and the air guide plate 500 cooperate with each other at the upper and lower sides of the lower air outlet 120 to guide the airflow blown out of the lower air outlet 120, 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 120, and can also reduce the airflow backflow to the lower air outlet 120 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.

[0065] Specifically, according to the different matching positions of the front baffle 400 and the air guide plate 500, the quick adjustment mode may include a first cooling air guide mode and a heating air guide mode, wherein:

[0066] In the first cooling air flow mode, Fig. 9 and Fig.10As shown, the front baffle 400 avoids the first wind dissipation structure and extends forward horizontally, and the air guide plate 500 opens the lower air outlet 120 and extends forward. The airflow of the main air duct 110 is mainly blown out through the lower air outlet 120, and the front baffle 400 and the air guide plate 500 are respectively separated and guided above and below the lower air outlet 120 to form a front guide air duct 620 extending forward. The cold airflow blown out through the lower air outlet 120 can be blown forward for a longer distance under the guidance of the front guide air duct 620, thereby realizing rapid cooling adjustment of the indoor environment.

[0067] In the heating and air conduction mode, Fig.11 and Fig.12 As shown, the front baffle 400 avoids the first wind dispersing structure 230 and extends downward, and the air guide plate 500 opens the lower air outlet 120 and extends downward. The airflow of the main air duct 110 is mainly blown out through the lower air outlet 120, and the front baffle 400 and the air guide plate 500 respectively guide the air at the front and rear sides of the lower air outlet 120 to form a lower guide air duct 630 extending downward. The hot air flow blown out through the lower air outlet 120 can be blown downward to the ground under the guidance of the lower guide air duct 630, thereby realizing rapid heating and regulation of the indoor environment.

[0068] When the front baffle 400 is hinged to the upper edge of the lower air dispersion area 220, similar to the first cooling air guide mode, the air conditioner indoor unit also has a second cooling air guide mode. In the second cooling air guide mode, Fig.16 As shown, the front baffle 400 avoids the first wind dispersing structure 230 and extends forward horizontally, and the wind guide plate 500 opens the lower air outlet 120 and extends forward. The airflow of the main air duct 110 is blown out through the lower air outlet 120, wherein the wind guide plate 500 guides the air forward at the lower side of the lower air outlet 120, so that the airflow blown out through the lower air outlet 120 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, the front baffle 400 rotates to extend forward approximately horizontally, and the front baffle 400 can be blocked at the upper side of the first wind dispersing structure 230, thereby reducing the occurrence of the airflow blown out through the lower air outlet 120 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.

[0069] Preferably, if Figure 1-Figure 3 As 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 245, and the shape and size of the receiving groove 245 match the front baffle 400. When the air conditioner is in the off state, the front baffle 400 can be embedded in the receiving groove 245 when it rotates to cover the first wind dispersing structure 230, which not only ensures the air tightness of the covering of the first wind dispersing structure 230, 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.

[0070] In this embodiment, Figure 1 As shown, the air guide plate 500 is provided with a third air dispersing structure 510. The third air dispersing structure 510 on the air guide plate 500 can disperse the airflow passing through it, wherein, since the lower air outlet 120 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 120 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 third air dispersing structure 510 is small, which can ensure the cleanliness and smoothness of the third air dispersing structure 510, thereby ensuring its air dispersing function.

[0071] When the air conditioner is in use, in the quick adjustment mode, the air guide plate 500 opens the lower air outlet 120, and the third wind dispersion structure 510 has little effect on the flow conductivity of the guide surface of the air guide plate 500, which can ensure that the air guide plate 500 guides the air out of the lower air outlet 120 normally. In the wind dispersion mode, the front baffle 400 can be opened as described above to avoid the first wind dispersion structure 230, and the air guide plate 500 can be closed to close the lower air outlet 120. At this time, the first wind dispersion structure 230 located on the front end plate and the third wind dispersion structure 510 located on the air guide plate 500 can both discharge air and disperse the air flow, so that the indoor unit of the air conditioner has forward wind dispersion through the first wind dispersion structure 230 and forward and downward wind dispersion through the third wind dispersion structure 510, thereby increasing the wind dispersion area and range of the indoor unit of the air conditioner, and improving the wind dispersion effect of the indoor unit of the air conditioner; In addition, the front baffle 400 can be closed so that its covering area covers the first wind dispersion structure 230, and the wind guide plate 500 can be closed at the same time to close the lower air outlet 120. Then, the first wind dispersion structure 230 located on the front end plate is closed by the covering area of ​​the front baffle 400, and the airflow in the main air duct 110 can be blown out through the third wind dispersion structure 510 on the wind guide plate 500 and the blowing process is dispersed, so that the indoor unit of the air conditioner has a downward and forward wind dispersion outlet, thereby making the types of wind dispersion modes of the indoor unit of the air conditioner more diverse, and correspondingly further improving the functionality of the indoor unit of the air conditioner and the air conditioner as well as the user comfort.

[0072] When the wind guide plate 500 is provided with a third wind dispersion structure 510 and the front baffle 400 is hinged to the lower edge of the lower wind dispersion area 220, the wind dispersion mode may include a lower wind dispersion mode, the double wind dispersion mode may include a first wind dispersion mixed mode, and the single wind dispersion mode includes a first full wind dispersion mode.

[0073] Specifically, in the downward wind mode, Figure 1 and Figure 2As shown, the front baffle 400 blocks the front end surface of the first wind dispersing structure 230, and the wind guide plate 500 closes the lower air outlet 120. The front baffle 400 rotates upward and is approximately close to the front end surface of the first wind dispersing structure 230. The first wind dispersing structure 230 is completely located in the area where the front baffle 400 is located, and the covering area of ​​the front baffle 400 can completely block the front port of the first wind dispersing structure 230. Then, the airflow in the main air duct 110 can be blown out through the third 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 outlet.

[0074] In the first diffuse wind mixing mode, Figure 3 and Figure 4 As shown, the air guide plate 500 closes the lower air outlet 120, and the angle between the front baffle plate 400 and the lower wind dispersion area 220 ranges from 20° to 45°. The front baffle 400, 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 of the airflow of the main air duct 110 flows into the wind dispersion duct 300 through the connecting port 310, and most of the primary scattered air dispersed and blown out by the first wind dispersion structure 230 is blown forward to the front baffle 400, and is dispersed again by the second wind dispersion structure 410 thereon to become secondary scattered air and blown forward, thereby ensuring the secondary dispersion treatment of the primary scattered air by the second wind dispersion structure 410, and correspondingly forming a breeze feeling area with fine and dispersed airflow in front of the air conditioner indoor unit; at the same time, a small part of the airflow reaching the front baffle 400 can flow forward and upward under the guiding effect of the front baffle 400, thereby reaching a farther distance in front of the air conditioner indoor unit, and correspondingly increasing the range of the breeze feeling area. Another part of the airflow in the main air duct 110 is blown downwardly and forwardly through the third wind dispersion structure 510 on the air guide plate 500, and is dispersed during the blowing process, thereby forming a breeze feeling area with a slightly higher wind speed at the front and lower part of the air conditioner indoor unit; and in this mode, the wind dispersion outlet area and the wind dispersion outlet range are both large, which can effectively improve the wind dispersion effect and temperature regulation effect of the air conditioner indoor unit. The user can be located in the corresponding wind dispersion area as needed, and the air conditioner indoor unit has strong functionality and high user comfort.

[0075] In the first full diffuse wind mode, Figure 5 and Figure 6As shown, the angle between the front baffle 400 and the lower wind dispersing area 220 is in the range of 90° to 120°. Preferably, the front baffle 400 extends forward horizontally; the wind guide plate 500 closes the lower air outlet 120. The front baffle 400 extending forward horizontally does not block the first wind dispersing structure 230 and the third wind dispersing structure 510 of the wind guide plate 500. The first wind dispersing structure 230 and the plurality of third wind dispersing structures 510 can form a wind dispersing structure with a larger overall wind dispersing area. After a part of the airflow of the main air duct 110 enters the wind dispersing duct 300, it is dispersed and blown forward by the first wind dispersing structure 230; the other part is dispersed and blown downward and forward by the third wind dispersing structure 510 on the wind guide plate 500, thereby forming a wind dispersing area with a balanced wind feeling and a larger wind dispersing range at the front and lower part of the air conditioner indoor unit. The front baffle 400 extending forward can guide the primary scattered wind blown out through the first scattered wind structure 230 forward, so that the scattered wind can be blown forward over a greater distance, thereby further increasing the range of the scattered wind area formed in the front lower part of the air conditioner indoor unit.

[0076] When the front baffle 400 is hinged to the lower edge of the lower wind dispersion area 220, the indoor unit of the air conditioner also has a mixed air mode. In the mixed air mode, Figure 7 and Figure 8 As shown, the front baffle plate 400 avoids the first wind dispersing structure 230 and extends downward, the air guide plate 500 opens the lower air outlet 120 and extends forward, and the front baffle plate 400 and the air guide plate 500 overlap each other. The air 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 air guide plate 500, or the front end of the air guide plate 500 overlaps the rear end surface of the front baffle 400, or the front end of the air guide plate 500 overlaps the bottom end of the front baffle 400; when the air guide plate 500 is provided with a third wind dissipation structure 510, at this time, the first wind dissipation structure 230 located on the front end plate is in an open state, the second wind dissipation structure 410 of the front baffle 400 is in an open state, and the third wind dissipation structure 510 on the air guide plate 500 is in an open state, the front baffle 400 and the air guide plate 500 jointly block the lower air outlet 120 and the left and right ends of the two form end air outlets 610.

[0077] When the air conditioner is running, since the lower air outlet 120 of the main air duct 110 is blocked by the front baffle 400 and the air guide plate 500 and has a large wind resistance, a part of the airflow of the main air duct 110 flows into the scattered air duct 300 through the connecting port 310, and then is dispersed and blown forward through the first scattered air structure 230; the other part of the airflow is blown out through the lower air outlet 120 and is divided into three airflows, one of which is dispersed and blown downward through the third scattered air structure 510 of the air guide plate 500, another airflow is dispersed and blown forward through the second scattered air structure 410 of the front baffle 400, and another airflow is dispersed and blown forward through the left and right end air outlets 61 as shown by the dotted arrows. 0 blows out to the left and right; the mixed air mode can make the air conditioner indoor unit have the forward air dispersion outlet through the first air dispersion structure 230, the forward air dispersion outlet through the second air dispersion structure 410, the downward air dispersion outlet through the third air dispersion structure 510, and the rapid air discharge to the left and right through the two end air outlets 610, so that a larger air dispersion area is formed in front of the air conditioner indoor unit, and the left and right side areas of the air conditioner indoor unit corresponding to the two end air outlets 610 are blowing areas with stronger wind force. At the same time, the rapid air discharge of the end air outlets 610 can ensure the rapid temperature adjustment of the indoor environment by the air conditioner, thereby greatly improving the functionality of the air conditioner indoor unit and the air conditioner.

[0078] Among them, in the mixed air mode, in addition to the third wind dispersing structure 510 mentioned above, the air guide plate 500 can also be a closed plate body. When the air conditioner is running, the difference from the above-mentioned air guide plate 500 being provided with the third wind dispersing structure 510 is that ventilation cannot be achieved at the air guide plate 500, and the range of the wind dispersing area formed on the front side of the air conditioner indoor unit is slightly smaller.

[0079] In addition to being hinged to the lower edge of the lower wind dispersion area 220 as mentioned above, the front baffle 400 can also be hinged to the upper edge of the lower wind dispersion area 220. When the air guide plate 500 is provided with a third wind dispersion structure 510, the wind dispersion mode can include a lower wind dispersion mode, and its double wind dispersion mode can include a second wind dispersion mixed mode, and the single wind dispersion mode includes a second full wind dispersion mode.

[0080] Specifically, the downward wind dispersion mode, such as Fig.13 As shown, the front baffle 400 is hinged to the lower edge of the lower wind dispersing area 220, which is the same as the lower wind dispersing mode. The front baffle 400 covers the first wind dispersing structure 230, and the wind guide plate 500 closes the lower air outlet 120. When the air conditioner is running, the airflow in the main air duct 110 can be blown out through the third wind 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.

[0081] In the second diffuse wind mixing mode, Fig.14As shown, the air guide plate 500 closes the lower air outlet 120, and the front baffle plate 400 and the lower wind dispersion area 220 form an angle of 20° to 45°. The front baffle plate 400, which forms 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 first wind dispersion structure 230, and has a small distance from the first wind dispersion structure 230. A part 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 400, and is dispersed again by the second wind dispersion structure 410 thereon to become secondary wind and blown forward, thereby ensuring that the second wind dispersion structure 410 disperses the primary wind for the secondary time, and accordingly forms a wind dispersion area in front of the indoor unit of the air conditioner with fine and soothing airflow dispersion; at the same time, another part of the airflow in the main air duct 110 passes through the air guide plate The third wind dispersion structure 510 on 500 blows downward and forward, and the blowing process is dispersed, thereby forming a wind dispersion area with slightly higher wind speed in the front and lower part of the air conditioner indoor unit; wherein, a small part of the airflow reaching the front baffle 400 can flow forward and downward under the guiding effect of the front baffle 400, so that the wind dispersion area blown out by the first wind dispersion structure 230 can be connected with the wind dispersion area blown out by the third wind dispersion structure 510, so that the wind dispersion area formed in front of the air conditioner indoor unit is large and the wind dispersion balance is high; and in this mode, the wind dispersion area and the wind dispersion range are both large, which can effectively improve the wind dispersion effect and temperature regulation effect of the air conditioner indoor unit, and the user can be located in the corresponding wind dispersion area as needed, and the air conditioner indoor unit has strong functionality and high user comfort.

[0082] In the second full diffuse wind mode, Fig.15 As shown, the angle between the front baffle 400 and the lower wind dispersing area 220 is in the range of 90° to 120°. Preferably, the front baffle 400 extends horizontally forward, and the wind guide plate 500 closes the lower air outlet 120. The front baffle 400 extending horizontally forward does not block the first wind dispersing structure 230 and the third wind dispersing structure 510 of the wind guide plate 500. The first wind dispersing structure 230 and the plurality of third wind dispersing structures 510 can form a wind dispersing structure with a larger overall wind dispersing area. After a part of the airflow of the main air duct 110 enters the wind dispersing duct 300, it is dispersed and blown forward by the first wind dispersing structure 230; the other part is dispersed and blown downward and forward by the third wind dispersing structure 510 on the wind guide plate 500, thereby forming a wind dispersing area with a balanced wind feeling and a larger wind dispersing range at the front and lower part of the air conditioner indoor unit. Among them, the front baffle 400 extending forward can block between the first wind dissipation structure 230 and the air inlet on the top of the shell 10, thereby effectively reducing the loss of air volume caused by the airflow blown out through the first wind dissipation structure 230 flowing back upward to the air inlet, and correspondingly ensuring the temperature regulation effect of the air conditioner indoor unit and the air conditioner on the indoor environment.

[0083] 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.

[0084] In this embodiment, Figure 1 and Figure 3 As shown, the left end plate and the right end plate 130 of the housing 10 and the area corresponding to the wind dispersing duct 300 are provided with a fourth wind dispersing structure 131. In the wind dispersing mode, the airflow of the wind dispersing duct 300 is dispersed and blown out through the first wind dispersing structure 230 at the front side, and can also be dispersed and blown out through the fourth wind dispersing structures 131 at the left and right ends thereof, thereby increasing the wind dispersing area of ​​the wind dispersing duct 300 and improving the wind dispersing effect and temperature regulation effect in the wind dispersing mode.

[0085] Optionally, the first wind dispersion structure 230, the second wind dispersion structure 410, the third wind dispersion structure 510 and the fourth wind dispersion structure 131 can adopt a plurality of dispersedly arranged wind dispersion holes, or set mounting holes on the corresponding plate bodies, and rotatably connect impellers in the mounting holes, or other structures that can ventilate and disperse the airflow can be used; wherein, the shape, number and position of the wind dispersion holes in the drawings are shown as examples and are not intended to be actual limitations.

[0086] Specifically, in this embodiment, when the first wind dispersing structure 230 is in the form of wind dispersing holes, Figure 2As shown, the wind 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 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.

[0087] Of course, when the second wind dispersion structure 410, the third wind dispersion structure 510 and the fourth wind dispersion structure 131 are in the form of wind dispersion holes, the above-mentioned staggered holes 231 can also be used; and it should be noted that the shape, number and arrangement position of the wind dispersion holes, etc. in the figure are only shown as examples and are not intended to be limiting.

[0088] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
