Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example to a wall-mounted air conditioning indoor unit with a double-layer grille and an air conditioner. Background Technology

[0002] Air conditioners are common appliances used to improve the indoor environment for users. Their temperature regulation capabilities and air delivery methods are all related to the user's experience when using air conditioners.

[0003] With the increasing popularity of air conditioners, users are not only concerned about how quickly they heat and cool, but also about the comfort of the air conditioner during the air delivery process.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Existing air conditioners have a relatively simple air outlet method. In cooling mode, the cold air from the indoor unit of a traditional wall-mounted air conditioner blows directly onto the user's body for a long time, which can easily cause discomfort and is detrimental to the user's health. This is especially true for the elderly and children, who are more likely to catch colds and other problems, thus reducing the user experience.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a wall-mounted air conditioner indoor unit and an air conditioner with a double-layer grille to solve the problem of the air conditioner having a single air outlet mode, which affects the user experience.

[0009] In some embodiments, a wall-mounted air conditioner indoor unit with a double-layer grille includes: a housing having a front air outlet at the front, a lower air outlet at the bottom, and a side air outlet at the side, the front air outlet, the lower air outlet, and the side air outlet being interconnected and all connected to an air outlet channel within the housing; the housing including a housing sidewall at the side; and a front panel assembly disposed at the front of the housing, slidably configured to open or close the front air outlet. When the front panel assembly is in a first position with the front air outlet closed, air is delivered from the side air outlet. The front panel assembly includes a front cover plate at the front and a front side plate at the side, the side air outlet being located on the front side plate. The housing sidewall includes a sleeved sidewall portion fitted onto the outside of the front side plate. The side air outlet has a first layer grille located on the inner side and a second layer grille located on the outer side.

[0078] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0079] This disclosure provides an indoor unit for an air conditioner.

[0080] Optionally, the indoor unit of the air conditioner includes a housing 1, a front panel assembly 101, and an inner guide plate 14. The housing 1 is provided with a front air outlet 11 at the front, a lower air outlet 12 at the bottom, and a side air outlet 13 at the side. The front air outlet 11, the lower air outlet 12, and the side air outlet 13 are all interconnected and connected to the air outlet duct 2 inside the housing 1. The front panel assembly 101 is located at the front of the housing 1, and at least a portion of the front panel assembly 101 is slidably configured to open or close the front air outlet 11. The inner guide plate 14 is located at the front air outlet 11 and the lower air outlet 12 of the housing 1. When the current panel assembly 101 is in the first position with the front air outlet 11 closed, and the inner guide plate 14 is rotated to the air distribution position 1401, air is sent out from the lower air outlet 12 and the side air outlet 13; when the current panel assembly 101 is in the first position with the front air outlet 11 closed, and the inner guide plate 14 is rotated to the downward air guiding position 1403, air is sent out from the lower air outlet 12.

[0081] The housing 1 has interconnected front air outlet 11, lower air outlet 12, and side air outlet 13, all of which are connected to the air outlet duct 2 inside the housing 1. This allows the air conditioning unit's heat exchanger to deliver air through one or more of these outlets, improving the versatility of the air outlets and enhancing user experience.

[0082] The air conditioning indoor unit provided in this embodiment can achieve the following air supply modes:

[0083] Airflow Mode 1: Multi-directional airflow mode. The front panel assembly 101 is in the first position with the front air outlet 11 closed, and the inner guide plate 14 rotates to the air distribution position 1401. Air conditioning air from the indoor unit is delivered from the lower air outlet 12 and the side air outlets 13. When there are two side air outlets 13, the indoor unit achieves a three-sided wraparound airflow mode, preventing direct airflow onto the user and improving the user experience. Figure 3 and Figure 4 As shown.

[0084] Airflow Mode Two: Downward Airflow Mode. The front panel assembly 101 is in the first position with the front air outlet 11 closed, and the inner guide plate 14 rotates to the downward airflow position 1403. At this time, due to the obstruction effect of the inner guide plate 14, the air conditioning air from the indoor unit is delivered from the downward air outlet 12. This airflow mode is suitable for users such as the elderly and children, preventing them from catching colds or other problems. Figure 5 As shown.

[0085] Airflow Mode 3: Maximum Airflow Mode. The front panel assembly 101 is positioned in the second open air outlet 11 position, and the inner guide plate 14 rotates to the air distribution position 1401. At this time, most of the air conditioning air from the indoor unit will be delivered from the front air outlet 11. This mode is suitable for rapid cooling or rapid heating. Figure 6 As shown.

[0086] Airflow Mode 4: Cooling Upward Blowing Mode. The front panel assembly 101 is positioned in the second open air outlet 11 position, and the inner guide plate 14 rotates to the upward airflow guiding position 1402. At this time, the air conditioning air from the indoor unit is blown upward from the front air outlet 11. For example... Figure 7 As shown.

[0087] As can be seen, the air conditioner indoor unit provided in this embodiment can realize multiple air supply modes, meet different user needs, and improve user experience.

[0088] Optionally, such as Figure 2 The front air outlet 11 is located at the lower part of the front of the housing 1.

[0089] Optionally, the front panel assembly 101 can slide under the drive of the first driving device. When the front panel assembly 101 slides upward, the front air outlet 11 opens; when the front panel assembly 101 slides downward, the front air outlet 11 closes. Optionally, the first driving device can be a gear and rack drive device driven by a motor.

[0090] Optionally, the inner guide plate 14 can rotate under the drive of the second drive device, so that the inner guide plate 14 is in the upward air guiding, downward air guiding, and air distribution position 1401. Optionally, the second drive device can be a gear-type drive device driven by an electric motor.

[0091] It is understandable that the inner guide plate 14 is rotated to the air distribution position 1401 so that the airflow through the outer wall and inner wall of the inner guide plate 14 is approximately the same. For example, when the front panel assembly 101 is in the first position with the front air outlet 11 closed, and the inner guide plate 14 is rotated to the air distribution position 1401, part of the airflow from the air outlet duct 2 of the indoor air conditioning unit flows through the inner wall of the inner guide plate 14 and is delivered from the side air outlet 13, while the other part flows through the outer wall of the inner guide plate 14 and is delivered from the lower air outlet 12. Alternatively, the air distribution position 1401 to which the inner guide plate 14 is rotated can also be understood as a position between the upward airflow position and the downward airflow position.

[0092] Optionally, the front panel assembly 101 includes a front cover plate 1011 and an inner partition plate 1012 located on one side of the inner wall of the front cover plate 1011. The front cover plate 1011 and the inner partition plate 1012 form a front air outlet cavity 1013. A side air outlet 13 is disposed on the side of the front air outlet cavity 1013. The front air outlet cavity 1013 is connected to the air outlet channel 2 so that the air in the air outlet channel 2 enters the front air outlet cavity 1013 and is sent out from the side air outlet 13.

[0093] The front cover 1011 and the inner side panel of the front panel assembly 101 form a front air outlet cavity 1013, which is connected to the air outlet duct 2. A side air outlet 13 is located on the side of the front air outlet cavity 1013. Air conditioning air from the air outlet duct 2 of the indoor air conditioning unit can enter the front air outlet cavity and be discharged from the side air outlet 13.

[0094] The front cover 1011 and the inner partition 1012 are arranged in a front-rear direction, and the front cover 1011 is located in front of the inner partition 1012. The front cover 1011 can be the exterior panel of the air conditioner indoor unit. The inner partition 1012 is disposed between the front air outlet cavity 1013 and the heat exchanger inside the air conditioner indoor unit. Figure 8 As shown.

[0095] Optionally, the side air outlet 13 includes a first side air outlet located on one side of the front air outlet cavity 1013 and a second side air outlet located on the other side of the front air outlet cavity 1013. The side air outlet 13 includes a first side air outlet and a second side air outlet located on both sides of the front air outlet cavity 1013 respectively. In this way, when the front panel assembly 101 is in the first position of closing the front air outlet 11 and the inner guide plate 14 is rotated to the air distribution position 1401, the air from the indoor unit of the air conditioner can be simultaneously delivered from the lower air outlet 12, the first side air outlet, and the second side air outlet, realizing a three-sided wraparound air supply method, preventing the air conditioner air from blowing directly on the user, and improving the user experience.

[0096] Optionally, the air outlet width of the first side air outlet, the air outlet width of the second side air outlet, and the air outlet width of the front air outlet cavity 1013 are all the same.

[0097] Optionally, the front cover 1011 of the front panel assembly 101 can slide vertically as a whole to open or close the front air vent 11. The front cover 1011 can also slide vertically upwards under the action of the first drive device to open the front air vent 11, such as... Figure 6 As shown; the front cover 1011 slides downwards to close the front air vent 11, as... Figure 5 As shown.

[0098] Optionally, the maximum upward sliding distance of the front cover 1011 is a first distance, and the distance from the bottom of the inner partition 1012 to the lower air outlet 12 is a second distance, wherein the first distance is greater than or equal to the second distance. When the front cover 1011 opens the front air outlet 11, the maximum upward sliding distance of the front cover 1011 is the first distance H1, and the distance from the bottom of the inner partition 1012 to the lower air outlet 12 is the second distance H2. In this embodiment, H1 ≥ H2, thus ensuring that the front cover 1011 does not obstruct the front air outlet 11, which is beneficial for increasing the air volume delivered by the front air outlet 11.

[0099] It is understandable that the first distance H1 is the vertical distance between the bottom edge of the front cover 1011 and the air vent grille at the lower air vent 12; the second distance H2 is the vertical distance between the bottom edge of the inner partition 1012 and the air vent grille at the lower air vent 12, such as... Figure 9 As shown.

[0100] Optionally, the front cover 1011 of the front panel assembly 101 includes an upper cover portion 104 and a lower cover portion 105, and the lower cover portion 105 corresponds to the front air outlet 11. The lower cover portion 105 is slidable up and down to open or close the front air outlet 11. The front cover 1011 can also open or close the front air outlet 11 by partially sliding. In this embodiment, the front cover 1011 includes an upper cover portion 104 and a lower cover portion 105. When the front air outlet 11 is closed, the lower cover portion 105 of the front cover 1011 corresponds to the front air outlet 11 to block the front air outlet 11.

[0101] The lower cover 105 can slide upward under the action of the first drive device to open the front air outlet 11, such as Figure 11 and Figure 12 As shown; the lower cover 105 can slide downwards to close the front air outlet 11, as... Figure 1 As shown. Optionally, the surface area of ​​the lower cover portion 105 is larger than the air outlet area of ​​the front air outlet 11, thereby improving the blocking effect of the lower cover portion 105 on the front air outlet 11 when the front air outlet 11 is in the closed state.

[0102] Optionally, when the lower cover portion 105 is in the open front air outlet 11 state, the entire lower cover portion 105 slides upward to the inside of the upper cover portion 104, such as... Figure 11 and Figure 12 As shown.

[0103] Optionally, the upper cover portion 104 includes a first cover edge 1041 located at the bottom, and the distance from the bottom of the inner partition 1012 to the lower air outlet 12 is a second distance, wherein the height of the first cover edge 1041 is greater than or equal to the second distance.

[0104] When the lower cover portion 105 is in the open state of the front air outlet 11, the edge of the lower cover portion 105 is flush with the first cover edge 1041 at the bottom of the upper cover portion 104, or the edge of the lower cover portion 105 is located above the first cover edge 1041 at the bottom of the upper cover portion 104. In this embodiment, the height of the first cover edge 1041 at the bottom of the upper cover portion 104 is greater than the height of the first partition edge 10121. In this way, when the front air outlet 11 is in the open state, the upper cover portion 104 avoids obstructing the front air outlet 11, which is beneficial to improving the air volume delivered by the front air outlet 11.

[0105] Optionally, the height H3 of the first cover edge 1041 is the vertical distance between the first cover edge 1041 and the air outlet grille of the lower air outlet 12. For example... Figure 11 As shown.

[0106] Optionally, the air outlet duct 2 includes a first air duct plate 21 connected to the first partition edge 10121 of the inner partition 1012, wherein the extension line of the first air duct plate 21 through the first partition edge 10121 is a first extension line 211, and the first cover edge 1041 of the upper cover portion 104 is located below the first extension line 211. Figure 12 As shown.

[0107] Optionally, the first air duct plate 21 of the air outlet duct 2 is inclined upward along the air outlet direction. The first air duct plate 21 extends to a first extension line 211 through the edge 10121 of the first partition plate, and the first cover edge 1041 of the upper cover plate portion 104 is located below the first extension line 211. In this way, while avoiding the obstruction of the front air outlet 11 by the upper cover plate portion 104, the front air outlet 11 is not opened to an unnecessary size during air outlet, thus improving the aesthetic performance of the front air outlet 11 during air outlet.

[0108] Optionally, when the inner guide plate 14 is in the downward airflow position 1403, the lower air outlet 12 includes a first lower air outlet 121 located on one side of the outer wall of the inner guide plate 14 and a second lower air outlet 122 located on one side of the inner wall of the inner guide plate 14. When the inner guide plate 14 is in the downward airflow position 1403, the air in the air outlet duct 2 of the air conditioning indoor unit is sent out from the second lower air outlet 122.

[0109] The air outlet width of the lower air outlet 12 is greater than the air outlet width of the side air outlet 13. When the inner guide plate 14 is in the downward air guiding position 1403, a vertical line is drawn along the lower edge of the inner guide plate 14 to divide the lower air outlet 12 into a first lower air outlet 121 and a second lower air outlet 122. The first lower air outlet 121 is located on one side of the outer wall of the inner guide plate 14, and the second lower air outlet 122 is located on one side of the outer wall of the inner guide plate 14.

[0110] In this way, when the current air outlet 11 is closed and the inner guide plate 14 is in the downward airflow position 1403, the air in the air outlet duct 2 of the indoor unit of the air conditioner is sent out from the second lower air outlet 122.

[0111] Optionally, the area of ​​the first lower air outlet 121 is the first air outlet area, and the area of ​​the second lower air outlet 122 is the second air outlet area, wherein the first air outlet area is less than or equal to the second air outlet area.

[0112] The first lower air outlet 121 has an air outlet width of K1, and the second lower air outlet 122 has an air outlet width of K2. The air outlet lengths of the first lower air outlet 121 and the second lower air outlet 122 are the same. In this embodiment, K1 < K2, making the first air outlet area smaller than the second air outlet area. Thus, when the current air outlet 11 is closed and the inner guide plate 14 is in a downward airflow guiding position, the air volume delivered by the second lower air outlet 122 is increased.

[0113] Optionally, the indoor unit of the air conditioner also includes an air diversion component 3.

[0114] The air diversion component 3 is disposed on the side of the front panel assembly 101 facing the inside of the housing 1. When the front panel assembly 101 is in the first position with the front air outlet 11 closed and the inner guide plate 14 is rotated to the air diversion position 1401, the air in the air outlet 2 is diverted once by the inner guide plate 14, so that part of the air is sent out from the lower air outlet 12, and is diverted a second time by the air diversion component 3, so that part of the air is sent out from the side air outlet 13.

[0115] In this embodiment of the disclosure, the arrangement of the air diversion component 3 improves the air diversion effect to the side air outlet 13 and increases the air volume of the side air outlet 13.

[0116] Figure 16 A vector diagram showing the airflow diversion component 3 is provided. From... Figure 16 As can be seen, under the diversion effect of the air guiding and diverting component 3, the air passing through the inner guide plate 14 can enter the front air outlet cavity 1013 with minimal wind speed loss, thus increasing the air delivery speed of the side air outlet 13. Furthermore, it allows the air to fill the front air outlet cavity 1013, resulting in more uniform airflow at different positions along the entire height of the side air outlet 13. Especially when the fan speed is low, the air guiding and diverting component 3 can guide the lower wind speed air to the front air outlet cavity 1013 and deliver it from the side air outlet 13. Figure 16 The left image in the diagram is a vector diagram of the air supply of an indoor air conditioning unit with airflow diversion component 3. Figure 16 The right image in the middle is Figure 16 The left image shows an enlarged view of the airflow diversion component at point 3.

[0117] Figure 17 A vector diagram is provided without the airflow diversion component 3. From... Figure 17As can be seen, after being diverted by the inner guide plate 14, the airflow directly rushes towards the inner side of the front cover 1011, and the airflow direction is perpendicular to the front cover 1011. When the airflow rushes towards the inner side of the front cover 1011, the air loss is significant, resulting in a decrease in the air velocity flowing into the front air outlet cavity 1013. This reduces the airflow efficiency of the side air outlet 13. Furthermore, the airflow does not fill the entire front air outlet cavity 1013, resulting in very little airflow from the higher-positioned side air outlet 13. Figure 17 The left image shows the air supply vector diagram of the indoor unit of the air conditioner without the air diversion component 3. Figure 17 The right image in the middle is Figure 17 Enlarged view of the inner guide plate at point 14 in the middle left image.

[0118] The airflow from the air outlet duct 2 of the indoor unit of the air conditioner undergoes a first diversion via the inner guide plate 14. After diversion, part of the airflow flows through the upper side of the inner guide plate 14, and the other part flows through the lower side of the inner guide plate 14. The air flowing through the lower side of the inner guide plate 14 is then discharged from the lower air outlet 12. The air flowing through the upper side of the inner guide plate 14 undergoes a second diversion via the air guiding and diverting component 3. After diversion, part of the airflow flows upward through the air guiding and diverting component 3 and is discharged through the side air outlet 13, while the other part flows downward through the air guiding and diverting component 3 and is discharged through the lower air outlet 12. Figure 14 As shown. It can be seen that in this embodiment of the present disclosure, the air guiding and diverting component 3, as a structural component for secondary air diversion, improves the air delivery effect of the side air outlet 13.

[0119] Optionally, the front panel assembly 101 includes a front cover plate 1011 and an inner partition plate 1012 located on one side of the inner wall of the front cover plate 1011. The front cover plate 1011 and the inner partition plate 1012 form a front air outlet cavity 1013, and a side air outlet 13 is disposed on the side of the front air outlet cavity 1013. The air guiding and diverting component 3 is disposed on the inner wall of the front cover plate 1011.

[0120] In this embodiment of the present disclosure, the airflow guiding and diverting component 3 is disposed on the inner wall of the front cover plate 1011. Optionally, the airflow guiding and diverting component 3 is fixedly disposed on the inner wall of the front cover plate 1011.

[0121] Optionally, the air diversion component 3 is fixedly connected to the inner wall of the front cover 1011 and moves with the sliding of the front cover 1011. When the front panel assembly 101 is in the first position of closing the front air outlet 11, the air diversion component 3 is located between the front cover 1011 and the inner guide plate 14; when the front panel assembly 101 is in the second position of opening the front air outlet 11, the air diversion component 3 is located between the front cover 1011 and the inner partition 1012.

[0122] In this embodiment, the airflow diversion component 3 moves with the sliding of the front cover 1011. When the front panel assembly 101 is in the first position with the front air outlet 11 closed, the airflow diversion component 3 is located between the front cover 1011 and the inner guide plate 14, playing a secondary diversion role, such as... Figure 14 As shown. When the front panel assembly 101 is in the second position with the front air outlet 11 open, the air diversion component 3 is located between the front cover 1011 and the inner partition 1012, and does not perform a secondary air diversion function. Furthermore, it can block airflow from being delivered from the side air outlet 13, as... Figure 6 As shown.

[0123] Optionally, the air outlet height of the front air outlet 11 is a first air outlet height H1; when the front panel assembly 101 is in the first position of closing the front air outlet 11, the air diversion component 3 includes a diversion initial end facing the air outlet channel 2, and the distance between the diversion initial end and the lower air outlet 12 is a lower diversion height H4, wherein H4 < H1.

[0124] When the front panel assembly 101 is in the first position of closing the front air outlet 11, the air diversion component 3 is in the position of performing secondary diversion function, and the initial diversion end is the end of the air diversion component 3 facing the air outlet channel 2. It can be understood that the other end of the air diversion component 3 is the end connected to the front panel assembly 101.

[0125] In this embodiment of the disclosure, H4 < H1, such as... Figure 18 As shown, this allows the air after being divided by the inner guide plate 14 to be smoothly divided again at the initial diversion end of the air diversion component 3, improving the effect of the air diversion component 3 on the secondary diversion of the air after the first diversion and increasing the air volume of the side outlet 13. Optionally, H4≤1 / 2H1.

[0126] In this embodiment, the initial diversion end of the airflow guiding and diverting component 3 is approximately flush with the front end of the inner guide plate 14 at the airflow diversion position 1401, or slightly higher than the front end of the inner guide plate 14. This allows the airflow passing over the upper side of the inner guide plate 14 to better flow through the airflow guiding and diverting component 3 for secondary diversion, improving the airflow diversion effect of the airflow guiding and diverting component 3. Optionally, the value of H4 ranges from 30mm to 40mm.

[0127] Optionally, the air diversion component 3 includes an upper diversion guide plate 31 and a lower diversion guide plate 32, wherein the upper diversion guide plate 31 includes a first connection end 301 connected to the lower diversion guide plate 32, and the first connection end 301 faces the air outlet channel 2.

[0128] The upper diversion guide plate 31 of the airflow guiding and diverting component 3 can be used to guide air upwards so that air is delivered from the side air outlet 13, and the lower diversion guide plate 32 of the airflow guiding and diverting component 3 can be used to guide air downwards so that air is delivered from the lower air outlet 12 and the lower side air outlet 13. The upper diversion guide plate 31 and the lower diversion guide plate 32 have a first connecting end 301 connected to each other, and the first connecting end 301 can be the aforementioned diversion initial end. Optionally, with a horizontal plane as a reference, the upper diversion guide plate 31 and the lower diversion guide plate 32 are symmetrically arranged. Figure 14 and Figure 15 As shown. Optionally, the upper diversion guide plate 31 is a concave guide plate; and / or, the lower diversion guide plate 32 is a concave guide plate.

[0129] Optionally, the upper diversion guide plate 31 includes a second connection end 302 connected to the front panel assembly 101, wherein the angle between the outer tangent of the second connection end 302 and the horizontal line is a first angle A1, and 30°≤A1≤50°.

[0130] The first connecting end 301 is the initial diversion end of the upper diversion guide plate 31, and the second connecting end 302 is the diversion end of the upper diversion guide plate 31. In this embodiment, the angle between the outer tangent of the second connecting end 302 and the horizontal line is the first angle A1, and 30°≤A1≤50°. It can be understood that the first connecting end 301 of the upper diversion guide plate 31 is horizontally positioned, and the angle between the second connecting end 302 of the upper diversion guide plate 31 and the horizontal line is A1, and 30°≤A1≤50°. The entire air distribution path formed by the upper diversion guide plate 31 is not long, and this embodiment improves the upward air distribution effect of the upper diversion guide plate 31. Optionally, 30°≤A1≤40°. Figure 15 As shown in B in the diagram.

[0131] Optionally, the lower diversion guide plate 32 includes a third connection end 303 connected to the front panel assembly 101, wherein the angle between the outer tangent of the third connection end 303 and the horizontal line is a second angle A2, and 30°≤A2≤50°.

[0132] The first connecting end 301 is the initial diversion end of the lower diversion guide plate 32, and the third connecting end 303 is the diversion end of the lower diversion guide plate 32. In this embodiment, the angle between the outer tangent of the third connecting end 303 and the horizontal line is the second angle A2, and 30°≤A2≤50°. It can be understood that the first connecting end 301 of the lower diversion guide plate 32 is horizontally arranged, and the angle between the third connecting end 303 of the lower diversion guide plate 32 and the horizontal line is A2, and 30°≤A2≤50°. The entire air distribution path formed by the lower diversion guide plate 32 is not long, and this embodiment improves the downward air distribution effect of the lower diversion guide plate 32. Optionally, 30°≤A2≤40°. Optionally, A1=A2. Figure 15 As shown in B in the diagram.

[0133] Optionally, when the current panel assembly 101 is in the first position of closing the front air outlet 11, and the inner guide plate 14 is rotated to the downward airflow position 1403, the distance between the inner guide plate 14 and the airflow diversion component 3 is less than or equal to the first preset distance.

[0134] The distance between the initial end of the air diversion component 3 and the position corresponding to the initial end of the inner guide plate 14 can be taken as the distance L1 between the inner guide plate 14 and the air diversion component 3. Figure 19 and Figure 20 As shown. In this embodiment of the present disclosure, when the front panel assembly 101 is in the first position of closing the front air outlet 11, and the inner guide plate 14 is rotated to the downward airflow position, the distance L1 between the inner guide plate 14 and the airflow diversion component 3 is limited to be less than or equal to the first preset spacing. In this way, the downward airflow effect of the inner guide plate 14 is improved, and the airflow effect of the lower air outlet 12 is improved.

[0135] Optionally, the first preset spacing is less than or equal to 20mm. Optionally, the spacing L1 between the inner guide plate 14 and the air diversion component 3 can be 10mm, 13mm, 15mm, 18mm, or 20mm. Optionally, the spacing L1 between the inner guide plate 14 and the air diversion component 3 should not be too small, otherwise the rotation of the inner guide plate 14 will be affected by the setting of the air diversion component 3.

[0136] Optionally, the airflow diversion component 3 includes an upper diversion guide plate 31 and a lower diversion guide plate 32. The upper diversion guide plate 31 includes a first connecting end 301 connected to the lower diversion guide plate 32. When the inner guide plate 14 rotates to the downward airflow position 1403, the horizontal line where the first connecting end 301 is located falls into the middle section 142 of the guide plate located in the middle of the inner guide plate 14.

[0137] When the inner guide plate 14 rotates to the downward airflow position, along the height direction, the inner guide plate 14 is divided into the upper section 141 of the upper guide plate, the middle section 142 of the middle guide plate, and the lower section 143 of the lower guide plate, as follows. Figure 20 As shown in B in the figure. In this embodiment of the present disclosure, the horizontal line where the first connecting end 301 is located falls into the middle section 142 of the guide plate, so that the first connecting end 301 roughly corresponds to the middle part of the inner guide plate 14.

[0138] Optionally, the upper diversion guide plate 31 further includes a second connection end 302 connected to the front panel assembly 101, wherein when the inner guide plate 14 is rotated to the downward airflow position 1403, the horizontal line where the second connection end 302 is located falls into the upper section 141 of the guide plate located above the inner guide plate 14. The lower diversion guide plate 32 includes a third connection end 303 connected to the front panel assembly 101, wherein when the inner guide plate 14 is rotated to the downward airflow position 1403, the horizontal line where the third connection end 303 is located falls into the lower section 143 of the guide plate located below the inner guide plate 14.

[0139] In this way, the horizontal line where the second connecting end 302 of the uppermost diverting guide plate 31 is located falls into the upper section 141 of the inner guide plate 14, ensuring that the uppermost end of the upper diverting guide plate 31 is not set too high. The horizontal line where the third connecting end 303 of the lower diverting guide plate 32 is located falls into the lower section 143 of the inner guide plate 14, ensuring that the lowermost end of the lower diverting guide plate 32 is not set too low. This embodiment of the present disclosure limits the setting of the entire air diversion component 3 in the height direction, so that the air diversion component 3 can perform the secondary air diversion function without occupying too much space and reducing the width of the airflow channel.

[0140] Optionally, the width of the front air outlet cavity 1013 is a first width, and the width of the air guiding and diverting component 3 is a second width, wherein the first width is greater than or equal to the second width. For example... Figure 21 As shown, the width of the front air outlet cavity 1013 is a first width F1, and the width of the air guiding and diverting component 3 is a second width F2. In this embodiment, F1 ≥ F2. Thus, when the air guiding and diverting component 3 moves upward with the sliding of the front cover plate 1011, it can move smoothly within the front air outlet cavity 1013 without jamming. Figure 21 As shown.

[0141] Optionally, when the current panel assembly 101 is in the first position of closing the front air outlet 11, and the inner guide plate 14 is rotated to the air distribution position 1401, the distance between the inner guide plate 14 and the air distribution component 3 is less than or equal to the second preset distance.

[0142] The distance L2 between the inner guide plate 14 and the air diversion component 3 can be understood as the straight-line distance between the initial diversion end of the air diversion component 3 and the front end of the inner guide plate 14, such as... Figure 22 As shown. In this embodiment, L2 is less than or equal to the second preset spacing, so that the distance between the inner guide plate 14 and the air diversion component 3 is not too large, thus improving the secondary diversion effect of the air diversion component 3. Optionally, the second preset spacing is less than or equal to 30mm.

[0143] Optionally, when the current panel assembly 101 is in the first position of closing the front air outlet 11, and the inner guide plate 14 is rotated to the air distribution position 1401, the distance between the inner guide plate 14 and the air distribution component 3 is greater than or equal to the third preset distance.

[0144] In this embodiment, the distance L2 between the inner guide plate 14 and the air diversion component 3 is greater than or equal to a third preset distance. This prevents the distance between the inner guide plate 14 and the air diversion component 3 from being too small, thus reducing the noise of the air diversion component 3 during the diversion process. Optionally, the third preset distance is greater than or equal to 20mm. Optionally, L2 can be 20mm, 22mm, 25mm, 27mm, or 30mm.

[0145] It is understandable that the distance L1 or L2 between the inner guide plate 14 and the air guide component 3 can be adjusted by adjusting the size of the inner guide plate 14, the installation position of the inner guide plate 14 in the indoor unit of the air conditioner, and the size of the air guide component 3.

[0146] Optionally, the upper airflow guide plate 31 includes a first connecting end 301 connected to the lower airflow guide plate 32. When the current panel assembly 101 is in the first position with the front air outlet 11 closed, and when the inner guide plate 14 rotates to the airflow distribution position 1401, the horizontal line where the front end of the inner wall of the inner guide plate 14 is located is the first horizontal line, and the first connecting end 301 is located above the first horizontal line. Figure 23 As shown, the first horizontal line S1 is located at the front end of the inner wall of the inner guide plate 14, and the first connecting end 301 is located above S1. The airflow passing through the inner wall or upper part of the inner guide plate 14 has a certain upward force when it flows out from the front end of the inner wall of the inner guide plate 14, such as... Figure 16 and Figure 17 As shown. In this embodiment of the present disclosure, the first connecting end 301 is located above the first horizontal line S1, so that the initial position of the air diversion component 3 is on the upward path of the wind, thereby improving the upward air diversion effect of the secondary diversion of the air diversion component 3.

[0147] Optionally, the lower airflow guide plate 32 includes a third connection end 303 connected to the front panel assembly 101. When the front panel assembly 101 is in a first position with the front air outlet 11 closed, and when the inner guide plate 14 rotates to the airflow distribution position 1401, the third connection end 303 is located below the first horizontal line. The third connection end 303 of the lower airflow guide plate 32 being located below the first horizontal line S1 improves the downward airflow guiding effect of the lower airflow guide plate 32.

[0148] Optionally, the front panel assembly 101 also includes a front top plate 106 disposed on the top and a front side plate 107 disposed on the side, and a side air outlet 13 is opened on the front side plate 107, wherein the front cover 1011, the front top plate 106 and the front side plate 107 are integrally formed.

[0149] In this embodiment, the front cover plate 1011, the front top plate 106, and the front side plate 107 are integrally formed. This allows the integrally formed prefabricated component to be placed at the front of the inner partition 1012 to form the front air outlet cavity 1013. It is understood that when the front cover plate 1011 includes an upper cover plate portion 104 and a lower cover plate portion 105, the upper cover plate portion 104, the front top plate 106, and the front side plate 107 of the front cover plate 1011 are integrally formed.

[0151] Optionally, the front panel assembly 101 also includes a front bottom plate 108 disposed at the bottom, and a lower air outlet 12 is formed on the front bottom plate 108, wherein the front cover plate 1011, the front top plate 106, the front side plate 107, and the front bottom plate 108 are integrally formed. This allows the integrally formed prefabricated component to be placed as follows: Figure 25 The front portion of the inner partition 1012 shown is used to obtain the front air outlet cavity 1013. It can be understood that when the front cover 1011 includes an upper cover portion 104 and a lower cover portion 105, the upper cover portion 104, the front top plate 106, the front side plate 107 and the front bottom plate 108 of the front cover 1011 are integrally formed.

[0152] Optionally, the front floor panel 108 is grille-shaped and has a lower air vent grille for downward airflow, such as... Figure 24 As shown.

[0153] Optionally, the width of the side air outlet 13 is the first air outlet width CK1, and the width of the lower air outlet 12 is the second air outlet width CK2, wherein CK1 < CK2; or, 2CK1 ≤ CK2.

[0154] The width of the side air outlet 13 can be the overall width of the side air outlet grille opened on the front side panel 107, or, when the width of the side air outlet 13 is the same as the width of the front air outlet cavity 1013, the first air outlet width CK1 of the side air outlet 13 is the same as the width of the front air outlet cavity 1013. Figure 21 The F1 shown is equal. The width of the lower air outlet 12 can be the overall width of the lower air outlet grille opened on the front bottom plate 108, or the second air outlet width CK2 of the lower air outlet 12 is... Figure 13 The sum of K1 and K2 in the equation.

[0155] In this embodiment of the disclosure, CK1 < CK2, that is, the air outlet width of the side air outlet 13 located on the side is less than the width of the bottom air outlet 12 located at the bottom. Optionally, twice CK1 is less than or equal to CK2.

[0156] Optionally, the lower cover portion 105 includes a baffle portion 1051 that blocks the front air outlet 11 and a sliding plate portion 1052 disposed on the upper part of the baffle portion 1051, wherein the inner wall of the upper cover portion 104 is provided with a sliding abutment portion for abutting the sliding plate portion 1052. The baffle portion 1051 and the sliding plate portion 1052 are integrally formed. When the lower cover portion 105 is in the closed state of the front air outlet 11, the baffle portion 1051 of the lower cover portion 105 blocks the front air outlet 11, and the sliding plate portion 1052 is located on one side of the inner wall of the upper cover portion 104, such as... Figure 28 As shown; when the lower cover portion 105 is in the state of opening the front air outlet 11, both the baffle portion 1051 and the sliding plate portion 1052 are located on one side of the inner wall of the upper cover portion 104, as shown. Figure 29 As shown.

[0157] In this embodiment of the present disclosure, the inner wall of the upper cover plate portion 104 is further provided with a sliding abutment portion for abutting against the sliding plate portion 1052, so as to limit the upward sliding stroke of the lower cover plate portion 105. For example... Figure 27 As shown.

[0158] Optionally, the sliding abutment part includes an abutment frame, which includes a top frame 1041 and side frame parts 1042 disposed on both sides of the top frame 1041. The sliding plate part 1052 is provided with abutment lugs 1053. When the lower cover plate part 105 is in the first position of closing the front air outlet 11, the side of the abutment lug 1053 abuts against the inner wall of the side frame part 1042 of the abutment frame. When the lower cover plate part 105 is in the second position of opening the front air outlet 11, the top of the abutment lug 1053 abuts against the inner wall of the top frame part 1041 of the abutment frame. The abutment frame is a strip-shaped structure protruding from the inner wall of the upper cover plate part 104. The abutment frame includes a top frame 1041 and side frame parts 1042, which are connected at right angles.

[0159] Optionally, the abutting lug 1053 of the sliding plate portion 1052 is provided on the upper part of the sliding plate portion 1052 and extends to the side, and is in the shape of a lug protruding to the side, such as... Figure 26As shown. Optionally, the abutment lug 1053 is integrally formed with the other parts of the lower cover plate 105. When the air outlet 11 is adjusted from the closed state to the open state, the abutment lug 1053 of the lower cover plate 105 slides upward along the side frame 1042, thus improving the sliding stability of the lower cover plate 105 during the upward sliding process. When the air outlet 11 is fully open, the top of the abutment lug 1053 abuts against the inner wall of the top frame 1041 of the abutment frame, and the side of the abutment lug 1053 abuts against the side frame 1042, as shown. Figure 29 As shown.

[0160] Optionally, the length of the front cover 1011 is greater than or equal to the first air outlet length of the front air outlet 11. For example...

[0161] Optionally, the inner wall of the front cover 1011 is provided with a connecting part 1043 that is connected to the inner partition 1012.

The lower cover portion 105 can slide up and down in the interlayer formed by the first upper cover portion and the second upper cover portion; the connecting member 1043 connected to the inner partition 1012 is disposed on the inner wall of the second upper cover portion.

[0164] Optionally, the distance between the front cover 1011 and the inner partition 1012 is the air outlet width F1 of the front air outlet cavity 1013, and F1 is greater than or equal to the first preset air path width. When the air outlet width is the same at different positions of the front air outlet cavity 1013, the width at any position is used as the air outlet width F1 of the front air outlet cavity 1013, such as... Figure 21 When the air outlet widths at different locations of the front air outlet cavity 1013 are different, the minimum width of the front air outlet cavity 1013 can be selected as the air outlet width F1. In this embodiment, F1 is greater than or equal to the first preset air path width, thereby increasing the air volume of the side air outlet 13.

[0165] Optionally, the width of the first preset air path is greater than or equal to 10mm. Optionally, 15mm ≤ F1 ≤ 30mm. Optionally, the value of F1 can be 10mm, 12mm, 15mm, 17mm, 20mm, 25mm, or 30mm. Optionally, when the air outlet width at different positions of the current air outlet cavity 1013 is different, the air outlet width at different positions is within the range of 10mm-30mm.

[0166] Optionally, the front air outlet 1013 includes a first air outlet portion 1014 and a second air outlet portion 1015, wherein the first air outlet portion 1014 is close to the air outlet channel 2, and the air outlet width CF1 of the first air outlet portion 1014 is smaller than the air outlet width CF2 of the second air outlet portion 1015; and / or, the air outlet height CH1 of the first air outlet portion 1014 is smaller than the air outlet height CH2 of the second air outlet portion 1015. In this embodiment, the first air outlet portion 1014 is disposed below the second air outlet portion 1015, and the first air outlet portion 1014 is directly connected to the air outlet channel 2. The air outlet width CF1 of the first air outlet portion 1014 is smaller than the air outlet width CF2 of the second air outlet portion 1015, which facilitates the flow of air flowing from the air outlet channel 2 into the first air outlet portion 1014 to the wider second air outlet portion 1015, thereby improving the air outlet uniformity at different positions of the side air outlet 13. Optionally, CH1 < CH2, thus increasing the overall airflow rate in the air outlet duct 2 towards the forward air outlet cavity 1013. For example... Figure 32 and Figure 33 As shown.

[0167] Optionally, the second air cavity 1015 includes a first air cavity end 10151 near the first air cavity 1014 and a second air cavity end 10152 near the top, wherein the air outlet width of the second air cavity 1015 gradually increases from the first air cavity end 10151 to the second air cavity end 10152. Optionally, the inner wall of the second air cavity 1015 is an outwardly convex arc shape, such as... Figure 34 As shown. In this way, especially when the fan speed is low, the uniformity and stability of the airflow at different positions of the side air outlet 13 are improved.

[0168] Optionally, the air outlet width of the first air chamber end 10151 is EQ1, and the air outlet width of the second air chamber end 10152 is EQ2, wherein EQ2 ≤ 2EQ1. The air outlet widths at both ends of the second air chamber 1015 should not differ too much; otherwise, when the fan speed is high, the high-speed air will flow into the wider second air chamber end 10152, reducing the air volume at the lower part of the side air outlet 13 and reducing the uniformity of air outlet 13.

[0169] Optionally, the indoor unit of the air conditioner also includes a heat exchanger disposed within the housing 1, and the heat exchanger includes a first heat exchange section 4 near the inner partition 1012, the distance between the first heat exchange section 4 and the inner partition 1012 being F3, wherein 18mm≤F3≤35mm. 0.68≤F1 / F3≤0.83.

[0170] The first heat exchange section 4 is the heat exchange section closest to the inner baffle 1012 in the heat exchanger. When the distance between the inner baffle 1012 and the first heat exchange section 4 is different at different positions, the minimum distance between the inner baffle 1012 and the first heat exchange section 4 is taken as F3, such as... Figure 34 As shown. Optionally, the distance F3 between the first heat exchange section 4 and the inner baffle 1012 can be 18mm, 20mm, 25mm, 30mm or 35mm. Optionally, F1 < F3.

[0171] Optionally, the rotation area formed by the rotation of the inner guide plate 14 is located inside the side air outlet 13. During airflow guidance, the inner guide plate 14 may have multiple rotation positions, such as... Figure 35 The upward air guiding position 1402, the air distribution position 1401, and the downward air guiding position 1403, etc., are all located inside the side air outlet 13 throughout the entire rotation process of the inner guide plate 14. Figure 35 As shown, this ensures that the rotation of the inner guide plate 14 does not interfere with the sliding of the front panel assembly 101.

[0172] Optionally, the air outlet duct 2 includes a first air duct plate 21 connected to the first partition edge 10121 of the inner partition 1012 and a second air duct plate 22 opposite to the first air duct plate 21. The first air duct plate 21 includes an inner air duct plate edge located at the inner end, and the inner guide plate 14 includes an inner guide plate edge located at the inner end. The line connecting the first point 2101 of the air duct plate edge and the second point 144 of the inner guide plate edge forms a first preset line 23, and the first preset line 23 passes through the third point of the second air duct plate 22. When the inner guide plate 14 rotates to the air distribution position 1401, the distance between the first point 2101 and the second point 144 is W1, and the distance between the second point 144 and the third point is W2. The difference between W2 and W1 is less than or equal to the first air distribution difference.

[0173] It is understandable that the first point 2101, the second point 144, and the third point are all located on the same longitudinal section of the indoor unit of the air conditioner, such as... Figure 36 As shown. In this embodiment, the difference between W2 and W1 is relatively small. Thus, when the inner guide plate 14 is located at the air distribution position 1401, the uniformity of the airflow flowing through the upper and lower sides of the inner guide plate 14 is improved.

[0174] Optionally, the first wind distribution difference value is less than or equal to 20mm. Optionally, the difference between W2 and W1 can be 0mm, 5mm, 10mm, 15mm, 20mm, etc. Optionally, the distance between the first point 2101 and the third point is W, where the first wind distribution difference value is less than or equal to 1 / 4W. It can be understood that W is the sum of W1 and W2.

[0175] The first air duct plate 21 includes an outer air duct plate edge located at the outer end, and the inner guide plate 14 includes an outer guide plate edge located at the outer end. The line connecting the fourth point 2102 of the outer air duct plate edge and the fifth point 145 of the outer guide plate edge forms a second preset line 24. The second preset line 24 intersects the extension line of the second air duct plate 22 at the sixth point. When the inner guide plate 14 rotates to the air distribution position 1401, the distance between the fourth point 2102 and the fifth point 145 is W3, and the distance between the fifth point 145 and the sixth point is W4. The difference between W3 and W4 is less than or equal to the second air distribution difference.

[0176] It is understandable that the fourth site 2102, the fifth site 145, and the sixth site are all located on the same longitudinal section of the indoor unit of the air conditioner, such as... Figure 37 As shown. In this embodiment, the difference between W3 and W4 is relatively small. Thus, when the inner guide plate 14 is located at the air distribution position 1401, the uniformity of the airflow flowing through the upper and lower sides of the inner guide plate 14 is improved.

[0177] Optionally, the second wind difference value is less than or equal to 30 mm.

[0178] Optionally, the difference between W2 and W1 is smaller than the difference between W3 and W4. This smaller difference between W2 and W1 results in better air distribution at the initial air distribution end of the inner guide plate 14 at the air distribution position 1401; the relatively larger difference between W3 and W4 causes the outer end of the inner guide plate 14 to be roughly upward-sloping, increasing the air distribution volume of the forward air outlet 1013, thereby improving the air outlet effect of the side air outlet 13. Whether the inner guide plate 14 has rotated to the air distribution position 1401 can be determined by a position sensor. For example, by obtaining the first difference between W2 and W1 and the second difference between W3 and W4, when the first difference is less than or equal to the first air distribution difference and the second difference is less than or equal to the second air distribution difference, it is determined that the inner guide plate 14 has rotated to the air distribution position 1401.

[0179] Optionally, the first air duct plate 21 of the air outlet duct 2 is inclined. The first air duct plate 21 is in the shape of an inclined plate.

[0180] Optionally, the perpendicular line passing through the second point 144 is a first preset perpendicular line 25, wherein the distance between the first preset perpendicular line 25 and the lower air outlet 12 is greater than or equal to 3mm.

[0181] When the inner guide plate 14 rotates to the air distribution position 1401, the first preset vertical line 25 passing through the second point 144 falls into the second air duct plate 22, and the distance W5 between the lower air outlet 12 and the first preset vertical line 25 is greater than or equal to 3mm. This improves the air distribution effect of the inner guide plate 14 at the air distribution position 1401. Optionally, the distance between the first preset vertical line 25 and the lower air outlet 12 can be 5mm, 8mm, 10mm, 15mm, etc.

[0182] Optionally, a double-layer grille is provided at the side air outlet. This prevents dust from entering the casing through the side air outlet, improving the cleanliness of the internal components of the air conditioner indoor unit.

[0183] Optionally, along the air outlet path of the side air outlet, one layer of the double-layer grille is located upstream of the air outlet path, and the other layer is located downstream of the air outlet path. In this way, the air delivered from the side air outlet passes through the double-layer grille before being delivered.

[0184] Optionally, the front panel assembly includes a front side panel disposed on the side, a side air outlet opened on the front side panel, and a housing including a housing side wall 15 disposed on the side. The housing side wall 15 includes a sleeved side wall portion sleeved on the outside of the front side panel. The double-layer grille includes a first layer grille 1071 located on the inner side and a second layer grille 152 located on the outer side. The first layer grille 1071 is opened on the front side panel, and the second layer grille 152 is opened on the sleeved side wall portion.

[0185] The first layer of grille 1071, located on the inner side of the front panel, and the second layer of grille 152, located on the outer side of the sleeved side wall portion, are both located on the inner side of the first layer of grille 1071. Optionally, the first layer of grille 1071 includes a plurality of vertically arranged grille bars, and the second layer of grille 152 also includes a plurality of vertically arranged grille bars.

[0186] Optionally, the first layer grille 1071 and the second layer grille 152 are alternately arranged, which improves the dust-blocking effect of the double-layer grille. Optionally, a preset gap is provided between the first layer grille 1071 and the second layer grille 152, which is greater than or equal to 10mm, so that the alternating double-layer grilles do not block the air outlet at the side air outlet.

[0187] Optionally, the first layer grille 1071 and the second layer grille 152 are arranged correspondingly, such as... Figure 40 As shown.

[0188] Optionally, the front cover of the front panel assembly can slide up and down as a whole to open or close the front air vents, and the first grille 1071 moves up and down as the front cover slides up and down.

[0189] The front cover plate, which can slide up and down, is integrally formed with the front side plate on which the first layer of grille 1071 is provided. In this way, the first layer of grille 1071 can move up and down as the front cover plate slides up and down. Figure 39 This diagram illustrates the opening of the front air vent with the front cover open, and the first-layer grille 1071 moving upwards with the front cover. This design improves the aesthetics of the air conditioner indoor unit's front air vent when it is open, thanks to the first-layer grille 1071. Furthermore, the first-layer grille 1071 enhances dust protection when the front air vent is open.

[0190] Optionally, the indoor unit of the air conditioner also includes a fresh air module, including a fresh air outlet 5 disposed on the top of the housing, wherein when the front cover slides upward to open the front air outlet, the distance between the fresh air outlet 5 and the front panel assembly is greater than or equal to a first clearance distance. The first clearance distance is greater than or equal to 10mm.

[0191] The indoor unit of the air conditioner is equipped with a fresh air module. The distance X1 between the fresh air outlet 5 and the front panel assembly is greater than or equal to the first clearance distance, so that the opening of the fresh air outlet 5 does not obstruct the vertical sliding of the front panel assembly. Optionally, the first clearance distance is greater than or equal to 10mm.

[0192] The side wall 15 of the housing is provided with a decorative grille 151 that blocks the air outlet duct. The decorative grille 151 is not connected to the air outlet duct, and the air in the air outlet duct is not sent out through the decorative grille 151. The decorative grille 151 improves the aesthetics of the air conditioning indoor unit with the side air outlet grille 1071. A second grille 152 is arranged adjacent to the decorative grille 151.

[0193] Decorative grille 151 is disposed at one end of the side wall 15 of the housing adjacent to the second grille 152, so that decorative grille 151 and second grille 152 form a continuous decorative effect.

[0194] Optionally, the fresh air outlet 5 is positioned above the top of the housing and angled towards the front panel assembly. For example... Figure 39 and Figure 40 As shown. In this way, when the front panel component opens the front air outlet, it will not obstruct the fresh air outlet 5 too much, thus improving the air outlet effect of the fresh air outlet 5.

[0195] Optionally, the side edge 1016 of the front hood protrudes beyond the first grille 1071. For example... Figure 41 and Figure 42 As shown.

[0196] In this embodiment, the side edge 1016 of the front cover protrudes from the first layer of grille 1071. This can also be understood as the side edge 1016 of the front cover extending from the first layer of grille 1071 towards the side of the housing. This improves the aesthetics of the front cover.

[0197] Optionally, the side edge 1016 of the front cover is flush with the second grille 152.

[0198] The side edge 1016 of the front cover is flush with the second layer grille 152 on the side of the housing. This makes the air conditioner indoor unit look better and more aesthetically pleasing when viewed from the side as the front cover slides up and down.

[0199] Optionally, the second layer grille 152 includes a first outer grille strip 1521 near the front cover plate, the distance between the first outer grille strip 1521 and the side edge 1016 of the front cover plate is the first grille spacing P1, and the distance between two adjacent outer grille strips in the second layer grille 152 is the second grille spacing P2, where P1 = P2.

[0200] like Figure 42 As shown in Figure A, P1 and P2 are equal, which makes the side edge 1016 of the front cover form an extension of the second layer of grille 152, improving the overall integrity and aesthetics of the air conditioning indoor unit.

[0201] Optionally, a transition block 1017 is provided between the first layer grille 1071 and the side edge 1016 of the front cover plate. The distance between the first layer grille 1071 and the side edge 1016 of the front cover plate is the third grille distance P3, and the distance between the first layer grille 1071 and the side edge of the transition block 1017 is the fourth grille distance P4, wherein P3 > P4.

[0202] The adapter block 1017 is disposed between the first layer grille 1071 and the side edge 1016 of the front cover plate, and the adapter block 1017 is disposed at the top position of the side edge 1016 of the front cover plate. Optionally, the front cover plate, the first layer grille 1071 and the adapter block 1017 are integrally formed. P3>P4, in the direction towards the side of the housing, the adapter block 1017 protrudes from the first layer grille 1071, and the side edge 1016 of the front cover plate protrudes from the adapter block 1017.

[0203] Optionally, the thickness of the adapter block 1017 is P5, where P5 < P1.

[0204] The thickness P5 of the adapter block 1017 is less than the first grille spacing P1 between the first outer grille strip 1521 and the side edge 1016 of the front cover plate. This ensures that the adapter block 1017 does not affect the up-and-down sliding of the front cover plate.

[0205] Optionally, the air conditioner provided in this embodiment is a split-type air conditioner, and the air conditioner also includes an outdoor unit.
