[0034] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0035] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 and Figure 2 As shown, the air conditioner 100 includes: a housing 1, a first air guide plate 2, and an air outlet grille 3. The housing 1 has an air outlet 11, which includes a first air outlet area 11a and a second air outlet area 11b. The first air outlet area 11a is connected to the rear side of the second air outlet area 11b. The housing 1 includes a front panel 12 located above the air outlet 11. The first air guide plate 2 is movably disposed on the housing 1 to open and close the first air outlet area 11a. The air outlet grille 3 covers the second air outlet area 11b and is detachably connected to the front panel 12.

[0036] The housing 1 is the outer contour of the air conditioner 100. The housing 1 has an air outlet 11. The air conditioner 100 discharges air through the air outlet 11 to regulate the indoor temperature. The air outlet 11 includes a first air outlet area 11a and a second air outlet area 11b. The first air outlet area 11a is connected to the rear side of the second air outlet area 11b. Here, "connected" means that there is no other structure blocking the first air outlet area 11a and the second air outlet area 11b, so that the airflow can flow smoothly between the first air outlet area 11a and the second air outlet area 11b, thereby improving airflow fluidity.

[0037] The first air guide plate 2 is movably disposed on the housing 1. Moving the first air guide plate 2 opens and closes the first air outlet area 11a. When the first air guide plate 2 closes the first air outlet, it prevents air from exiting the first air outlet area 11a. When the first air guide plate 2 opens the first air outlet area 11a, airflow can flow out from the first air outlet area 11a. Furthermore, when the first air guide plate 2 moves to open the first air outlet area 11a, it can also guide the airflow in and out of the air conditioner 100, thereby improving the airflow effect. For example, the first air guide plate 2 directs the airflow downwards, pressing the air outlet of the first air outlet area 11a, located at the rear, downwards, which is beneficial to the heat exchange effect of the air conditioner 100.

[0038] The air outlet grille 3 covers the second air outlet area 11b. By setting the air outlet grille 3, the air outlet of the second air outlet area 11b can be weakened and guided to a certain extent. Compared with the first air guide plate 2, which needs to move to guide the air, the air outlet grille 3 can guide the air without movement, which can reduce energy consumption. Furthermore, in conjunction with the airflow guidance of the first air guide plate 2, the air outlet effect of the air conditioner 100 can be improved.

[0039] In related technologies, the air outlet grille is integrated with the housing. However, the grille structure of the air outlet grille is prone to accumulating dust. Cleaning or maintaining the grille requires disassembling the entire air conditioner panel, which is inconvenient and has room for improvement.

[0040] In this embodiment of the utility model, the air outlet grille 3 of the air conditioner 100 is detachably connected to the front panel 12. When it is necessary to clean or maintain and replace the air outlet grille 3, the air outlet grille 3 can be detached from the front panel 12, thereby removing the air outlet grille 3 separately from the housing 1. The disassembly operation is convenient and reduces the difficulty of cleaning and maintaining the air outlet grille 3.

[0041] As an example, in this embodiment of the application, the air vent grille 3 is removed separately from the housing 1, including but not limited to: the position and posture of the front panel 11 do not need to be changed, and the air vent grille 3 is directly removed from the front panel 12; or, the front panel 12 is movably or detachably configured, and the front panel 12 has a first state and a second state. In the first state, the front panel 12 covers the front side of the housing 1. In the second state, the front panel 12 exposes at least part of the aforementioned front side of the housing 1, for example, the front panel 12 is flipped outward or the front panel 12 is removed. In the second state, the air vent grille 3 can be removed from the front panel 12.

[0042] According to the embodiment of the present utility model, the air conditioner 100 is designed with the air outlet grille 3 detachably connected to the front panel 12, so that the air outlet grille 3 can be removed separately from the housing 1. The disassembly operation is convenient and the difficulty of cleaning and maintaining the air outlet grille 3 is reduced.

[0043] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the upper end of the air vent grille 3 has a first limiting structure 31, and the front panel 12 has a second limiting structure 121. The first limiting structure 31 and the second limiting structure 121 can be separated and matched, and when the two are matched, the second limiting structure 121 can restrict the first limiting structure 31 from moving downward and forward.

[0044] The air vent grille 3 and the front panel 12 are limited and engaged by the first limiting structure 31 and the second limiting structure 121. Compared with the connection method of fasteners or other detachable connection, the mutual cooperation of the first limiting structure 31 and the second limiting structure 121 and the cancellation of the limiting are easier to operate, which can reduce the difficulty of installing and disassembling the air vent grille 3 and the front panel 12.

[0045] When the first limiting structure 31 and the second limiting structure 121 cooperate, they restrict the downward and forward movement of the air outlet grille 3 relative to the front panel 12. When the air outlet grille 3 covers the second air outlet area 11b, the backward movement of the air outlet grille 3 is restricted by the structure near the air outlet 11, and the upward movement of the air outlet grille 3 is restricted by the front panel 12. Therefore, the first limiting structure 31 and the second limiting structure 121 can stably limit the downward and forward movement of the air outlet grille 3, thereby improving the installation stability of the air outlet grille 3.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, there are multiple first limiting structures 31 and they are spaced apart in the left and right direction; and / or, the air outlet grille 3 has a ventilation area 3a and a first decorative area 3b, the ventilation area 3a is directly opposite to the second air outlet area 11b, the first decorative area 3b is located above the ventilation area 3a, the first limiting structure 31 is located in the first decorative area 3b, and the second limiting structure 121 is spaced apart above the air outlet 11.

[0047] Multiple first limiting structures 31 are arranged at intervals along the left-right direction. Correspondingly, multiple second limiting structures 121 are also arranged at intervals along the left-right direction. The second limiting structures 121 correspond one-to-one with the first limiting structures 31. By setting multiple first limiting structures 31, the air outlet grille 3 can be subjected to uniform force, improving the limiting effect of the air outlet grille 3 and enhancing the stability of the fit between the air outlet grille 3 and the front panel 12.

[0048] The air outlet grille 3 has a ventilation zone 3a and a first decorative zone 3b. The ventilation zone 3a is directly opposite the second air outlet area 11b, and the air from the second air outlet area 11b flows out through the ventilation zone 3a. The first decorative zone 3b is located above the ventilation zone 3a. No airflow passes through the first decorative zone 3b. By setting the first limiting structure 31 in the first decorative zone 3b, the corresponding second limiting structure 121, which cooperates with the first limiting structure 31, is also located above the air outlet 11. Neither the first limiting structure 31 nor the second limiting structure 121 will obstruct the airflow of the air conditioner 100, which is conducive to the rapid airflow of the air conditioner 100.

[0049] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the first limiting structure 31 and the second limiting structure 121 are hooked together.

[0050] The first limiting structure 31 and the second limiting structure 121 have a simple way of cooperating. The operation of cooperating with the first limiting structure 31 and the second limiting structure 121 and canceling the limiting is easier, which can reduce the difficulty of installing and removing the air vent grille 3 from the front panel 12.

[0051] In some embodiments of this utility model, such as Figure 4 As shown, the first limiting structure 31 has a hanging groove 311 with the opening facing forward, and the second limiting structure 121 extends downward and into the hanging groove 311 to be engaged with the upper side wall of the hanging groove 311.

[0052] When assembling the air vent grille 3 with the front panel 12, the air vent grille 3 is moved upward relative to the front panel 12, allowing the second limiting structure 121 on the front panel 12 to extend downward into the hanging groove 311. At this time, under the action of gravity, the weight of the air vent grille 3 causes the first limiting structure 31 to stop downward and abut against the second limiting structure 121. The second limiting structure 121 then hooks and engages with the first limiting structure 31, and the second limiting structure 121 abuts against the upper bottom of the hanging groove 311, thereby restricting the downward movement of the first limiting structure 31.

[0053] Furthermore, since the opening of the hanging groove 311 faces forward, the second limiting structure 121 extends into the hanging groove 311 from the front, and the second limiting structure 121 restricts the first limiting structure 31 from moving forward.

[0054] Therefore, the hook-and-loop engagement of the first limiting structure 31 and the second limiting structure 121 is simple, and can limit the air outlet grille 3 relative to the front panel 12 in both the vertical and horizontal directions, thereby improving the engagement stability of the air outlet grille 3 and the front panel 12.

[0055] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, a through hole 127 is provided on the front panel 12. The first limiting structure 31 extends from front to back through the through hole 127 to the rear side of the front panel 12. The second limiting structure 121 is located above the through hole 127 and on the front side of the front panel 12. When the first limiting structure 31 passes through the through hole 127 from top to bottom and from front to back, the second limiting structure 121 is accommodated from the front into the hanging groove 311, thereby completing the hook-and-hook engagement of the first limiting structure 31 and the second limiting structure 121.

[0056] In some embodiments of this utility model, such as Figure 4 , Figure 5 and Figure 6 As shown, the air vent grille 3 also has a third limiting structure 32, and the front panel 12 also has a fourth limiting structure 122. The third limiting structure 32 is located below the first limiting structure 31. The third limiting structure 32 and the fourth limiting structure 122 can be separated and engaged in the front-rear direction, and when the two are engaged, the fourth limiting structure 122 can restrict the third limiting structure 32 from moving downward.

[0057] The air vent grille 3 and the front panel 12 are not only connected by the first limiting structure 31 and the second limiting structure 121, but also by the third limiting structure 32 and the fourth limiting structure 122, which can further limit the air vent grille 3 and the front panel 12 and improve the installation stability of the air vent grille 3.

[0058] The third limiting structure 32 and the fourth limiting structure 122 can be disassembled and engaged in the front-back direction. Since the second limiting structure 121 can restrict the first limiting structure 31 from moving forward, the third limiting structure 32 and the fourth limiting structure 122 cannot be disassembled without disengaging the first limiting structure 31 and the second limiting structure 121. This improves the engagement stability of the third limiting structure 32 and the fourth limiting structure 122.

[0059] The third limiting structure 32 is located below the first limiting structure 31, and the fourth limiting structure 122 on the front panel 12 can restrict the third limiting structure 32 from moving downward. Thus, the fourth limiting structure 122 can support the third limiting structure 32. The weight of the air vent grille 3 is not only supported by the second limiting structure 121, but also by the fourth limiting structure 122, thereby making the cooperation stability of the first limiting structure 31 and the second limiting structure 121 stronger.

[0060] In some embodiments of this utility model, such as Figure 5 As shown, the third limiting structure 32 is multiple and spaced apart along the left-right direction and / or up-down direction; and / or, as Figure 2As shown, the air outlet grille 3 has a ventilation area 3a and a second decorative area 3c. The ventilation area 3a is directly opposite the second air outlet area 11b, and the second decorative area 3c is provided on the left and right sides of the ventilation area 3a respectively. The third limiting structure 32 is provided in the second decorative area 3c, and the fourth limiting structure 122 is provided at intervals on the left and / or right sides of the air outlet 11.

[0061] There may be multiple second limiting structures 121 that are spaced apart in the left-right direction, or multiple second limiting structures 121 that are spaced apart in the up-down direction, or multiple second limiting structures 121 that form a group that is spaced apart in the up-down direction, or multiple groups of second limiting structures 121 that are spaced apart in the left-right direction.

[0062] Correspondingly, there are also multiple fourth limiting structures 122, which are spaced apart along the left-right and / or up-down directions. The fourth limiting structures 122 correspond one-to-one with the third limiting structures 32. By setting multiple third limiting structures 32, the air outlet grille 3 can be subjected to uniform force, improving the limiting effect of the air outlet grille 3 and enhancing the stability of the fit between the air outlet grille 3 and the front panel 12.

[0063] The air outlet grille 3 has a ventilation zone 3a and a second decorative zone 3c. The ventilation zone 3a is directly opposite the second air outlet area 11b, and the air from the second air outlet area 11b flows out through the ventilation zone 3a. The second decorative zone 3c is located on the left and right sides of the ventilation zone 3a. No airflow passes through the second decorative zone 3c. By setting the third limiting structure 32 in the second decorative zone 3c, the corresponding fourth limiting structure 122, which cooperates with the third limiting structure 32, is also located on the left and right sides of the air outlet 11. Neither the third limiting structure 32 nor the fourth limiting structure 122 will obstruct the airflow of the air conditioner 100, which is conducive to the rapid airflow of the air conditioner 100.

[0064] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, at least one third limiting structure 32 forms a first limiting groove 321 with the opening facing rearward, and the corresponding fourth limiting structure 122 forms a first limiting protrusion 1221 that protrudes forward and extends into the first limiting groove 321; and / or, at least one third limiting structure 32 forms a second limiting protrusion 322 that protrudes rearward, and the corresponding fourth limiting structure 122 forms a limiting hole 1222, with the second limiting protrusion 322 extending into the limiting hole 1222.

[0065] The first limiting groove 321 is opened to the rear, and the first limiting protrusion 1221 protrudes forward and extends into the first limiting groove 321 to engage with and limit the first limiting groove 321. The second limiting protrusion 322 is set to protrude backward, and the limiting hole 1222 is open to the front. The second limiting protrusion 322 extends backward into the limiting hole 1222 to engage with and limit the limiting hole 1222.

[0066] Therefore, the third limiting structure 32 and the fourth limiting structure 122 can be disassembled and engaged in the front-back direction. The third limiting structure 32 can be engaged with the fourth limiting structure 122 by moving the third limiting structure 32 backward relative to the fourth limiting structure 122, and can be disassembled from the fourth limiting structure 122 by moving the third limiting structure 32 forward relative to the fourth limiting structure 122. The operation is simple.

[0067] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, a third limiting structure 32 has a first limiting groove 321 with its opening facing rearward, and a second limiting protrusion 322 that protrudes rearward. The first limiting groove 321 is located above the second limiting protrusion 322. Correspondingly, a fourth limiting structure 122 has a first limiting protrusion 1221 that protrudes forward and extends into the first limiting groove 321, and a limiting hole 1222 into which the second limiting protrusion 322 can extend. The first limiting protrusion 1221 is located above the limiting hole 1222. Thus, the cooperation between the third limiting structure 32 and the fourth limiting structure 122 forms an interlocking structure in the vertical direction, which can improve the stability of the fit between the air vent grille 3 and the front panel 12.

[0068] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the first limiting structure 31 and the second limiting structure 121 are configured to be separable after the air vent grille 3 is flipped forward from the installation state relative to the front panel 12 by more than a preset angle.

[0069] After the air vent grille 3 flips forward at a preset angle relative to the front panel 12, the lower end of the air vent grille 3 flips forward and the upper end of the air vent grille 3 moves backward. Then the first limiting structure 31 located at the upper end moves away from the second limiting structure 121, thereby separating the first limiting structure 31 and the second limiting structure 121.

[0070] The forward-flipping motion of the air vent grille 3 relative to the front panel 12 is simple and easy to operate, making it convenient to remove the air vent grille 3 from the front panel 12.

[0071] In some embodiments of this utility model, the air vent grille 3 also has a third limiting structure 32, and the front panel 12 also has a fourth limiting structure 122. The third limiting structure 32 is located below the first limiting structure 31, and the third limiting structure 32 and the fourth limiting structure 122 can be detached and fitted along the front-rear direction.

[0072] By configuring the first limiting structure 31 and the second limiting structure 121 so that they can be separated after the air vent grille 3 is flipped forward from the installation state relative to the front panel 12 by more than a preset angle, the cooperation of the third limiting structure 32 and the fourth limiting structure 122 is simultaneously released when the air vent grille 3 is flipped forward relative to the front panel 12, without the need for multiple steps, making it easier to remove the air vent grille 3 from the front panel 12.

[0073] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the air vent grille 3 also has a fifth limiting structure 33, which is located below the first limiting structure 31. The front panel 12 has a sixth limiting structure 4, which can be separated from and engaged with the fifth limiting structure 33. When the two are engaged, the sixth limiting structure 4 can restrict the fifth limiting structure 33 from flipping forward.

[0074] After the air vent grille 3 flips forward relative to the front panel 12 from its installed state beyond a preset angle, the first limiting structure 31 and the second limiting structure 121 disengage, thereby allowing the air vent grille 3 to be removed from the front panel 12. The fifth limiting structure 33, in conjunction with the sixth limiting structure 4, restricts the forward flipping of the fifth limiting structure 33, thus limiting the forward flipping of the air vent grille 3 relative to the front panel 12.

[0075] The cooperation of the fifth limiting structure 33 and the sixth limiting structure 4 can prevent the air outlet grille 3 from flipping relative to the front panel 12, thus preventing the air outlet grille 3 from being removed from the front panel 12. The cooperation of the fifth limiting structure 33 and the sixth limiting structure 4 acts as a safety lock, reducing the possibility of the air outlet grille 3 being accidentally separated from the front panel 12 due to external impact, and improving the working stability of the air outlet grille 3.

[0076] In some embodiments of this utility model, the air conditioner 100 is configured to satisfy at least one of the following structures: Figure 3 As shown, the fifth limiting structure 33 is located at the lower end of the air outlet grille 3; there are multiple fifth limiting structures 33, which are spaced apart along the left and right direction; as shown... Figure 7 As shown, the air outlet grille 3 has a ventilation area 3a and a second decorative area 3c. The ventilation area 3a is directly opposite the second air outlet area 11b, and the second decorative area 3c is provided on the left and right sides of the ventilation area 3a respectively. The fifth limiting structure 33 is provided in the second decorative area 3c, and the sixth limiting structure 4 is provided at intervals on the left and / or right sides of the air outlet 11.

[0077] By setting the fifth limiting structure 33 at the lower end of the air outlet grille 3, and by setting the fifth limiting structure 33 away from the first limiting structure 31, the limiting effect of the air outlet grille 3 flipping forward relative to the front panel 12 is better, which can improve the installation stability of the air outlet grille 3.

[0078] Multiple fifth limiting structures 33 are arranged at intervals along the left and right directions. Correspondingly, multiple sixth limiting structures 4 are also arranged at intervals along the left and right directions. The fifth limiting structures 33 and the sixth limiting structures 4 are arranged in a one-to-one correspondence. By setting multiple fifth limiting structures 33, the air outlet grille 3 can be subjected to uniform force, improving the limiting effect and enhancing the stability of the fit between the air outlet grille 3 and the front panel 12.

[0079] The air outlet grille 3 has a ventilation zone 3a and a second decorative zone 3c. The ventilation zone 3a is directly opposite the second air outlet area 11b, and the air from the second air outlet area 11b flows out through the ventilation zone 3a. The second decorative zone 3c is located on the left and right sides of the ventilation zone 3a. No airflow passes through the second decorative zone 3c. By setting the fifth limiting structure 33 in the second decorative zone 3c, the corresponding sixth limiting structure 4, which cooperates with the fifth limiting structure 33, is also located on the left and right sides of the air outlet 11. Neither the fifth limiting structure 33 nor the sixth limiting structure 4 will obstruct the airflow of the air conditioner 100, which is conducive to the rapid airflow of the air conditioner 100.

[0080] In some embodiments of this utility model, the sixth limiting structure 4 is detachable, movable relative to the front panel 12, retractable, or elastic, so that the sixth limiting structure 4 has a locked state and an unlocked state. In the locked state, the sixth limiting structure 4 is engaged with the fifth limiting structure 33. In the unlocked state, the sixth limiting structure 4 is disengaged from the fifth limiting structure 33.

[0081] The sixth limiting structure 4 can be detachably mounted relative to the front panel 12. The sixth limiting structure 4 can also be movable relative to the front panel 12, or it can be telescopic, or it can elastically deform. Of course, it is not limited to these; the sixth limiting structure 4 can also be a combination of the above-mentioned movements and deformations. The sixth limiting structure 4 has multiple ways to switch between locked and unlocked states, which can be selected according to actual needs, providing a wide range of options.

[0082] The sixth limiting structure 4 has a locked state and an unlocked state. When the sixth limiting structure 4 is locked, it cooperates with the fifth limiting structure 33 to restrict the air vent grille 3 from flipping forward relative to the front panel 12. When the sixth limiting structure 4 is unlocked, it disengages from the fifth limiting structure 33, and the air vent grille 3 can flip forward relative to the front panel 12 to release the assembly.

[0083] When switching between the locked and unlocked states, the sixth limiting structure 4 can be easily moved or detached from the front panel 12, or its shape can be altered by extending, retracting, or elastically deforming it. Engaging or disengaging the sixth limiting structure 4 from the fifth limiting structure 33 is also simple and convenient.

[0084] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the sixth limiting structure 4 can move relative to the front panel 12, and the fifth limiting structure 33 forms a second limiting groove 331 with the opening facing upward, downward, left or right; in the locked state, the sixth limiting structure 4 extends into the second limiting groove 331, and in the unlocked state, the sixth limiting structure 4 disengages from the second limiting groove 331.

[0085] The fifth limiting structure 33 has a second limiting groove 331. When the sixth limiting structure 4 is locked, it extends into the second limiting groove 331 to prevent the fifth limiting structure 33 from flipping forward. When the sixth limiting structure 4 is unlocked, it disengages from the second limiting groove 331, and the fifth limiting structure 33 can then flip forward.

[0086] The opening of the second limiting groove 331 can be set facing upward, downward, left, or right. Correspondingly, the sixth limiting structure 4 can extend downward, upward, right, or left into the second limiting groove 331. When the sixth limiting structure 4 extends into the second limiting groove 331, it can block the front of the wall of the second limiting groove 331, thereby preventing the fifth limiting structure 33 from flipping forward. The orientation of the opening of the fifth limiting structure 33 can be selected according to actual needs.

[0087] When the opening of the second limiting groove 331 faces backward, the sixth limiting structure 4 extending forward into the second limiting groove 331 cannot restrict the fifth limiting structure 33 from moving forward, or the structure of the sixth limiting structure 4 is complex, resulting in high manufacturing costs. When the opening of the second limiting groove 331 faces forward, the effect of the sixth limiting structure 4 extending backward into the second limiting groove 331 in restricting the fifth limiting structure 33 from moving forward is poor, or the structure of the sixth limiting structure 4 is complex, resulting in high manufacturing costs. Therefore, this utility model embodiment chooses to set the opening of the second limiting groove 331 to face upward, downward, left, or right.

[0088] In some embodiments of this utility model, such as Figure 4 and Figure 6As shown, the sixth limiting structure 4 can move relative to the front panel 12, and the fifth limiting structure 33 forms a second limiting groove 331 with the slot facing upward; in the locked state, the sixth limiting structure 4 moves downward to extend into the second limiting groove 331, and in the unlocked state, the sixth limiting structure 4 moves upward to disengage from the second limiting groove 331.

[0089] The sixth limiting structure 4 is positioned lower in the locked state than in the unlocked state. This allows the sixth limiting structure 4 to remain stable in the locked state under the influence of gravity, reducing the likelihood of the sixth limiting structure 4 being accidentally separated from the fifth limiting structure 33 due to impact.

[0090] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the front panel 12 also has a first limiting part 1231 and a second limiting part 1232. The first limiting part 1231 and the second limiting part 1232 are respectively detachably engaged with the sixth limiting structure 4. In the locked state, the first limiting part 1231 is engaged with the sixth limiting structure 4 to limit the movement of the sixth limiting structure 4; in the unlocked state, the second limiting part 1232 is engaged with the sixth limiting structure 4 to limit the movement of the sixth limiting structure 4.

[0091] The sixth limiting structure 4 can move relative to the front panel 12, and the front panel 12 has a first limiting part 1231 and a second limiting part 1232. The sixth limiting structure 4 can be detachably engaged with the first limiting part 1231 and the second limiting part 1232, thereby selectively stabilizing the sixth limiting structure 4 in a locked state and an unlocked state. This is beneficial to improving the assembly stability of the air vent grille 3 and the front panel 12, and can reduce the possibility of the sixth limiting structure 4 being lost after being separated from the front panel 12.

[0092] The "separable engagement" of the first limiting part 1231 and the second limiting part 1232 with the sixth limiting structure 4 is interpreted in a broad sense. The first limiting part 1231 and the second limiting part 1232 can be separated and assembled with the sixth limiting structure 4 by hand without the aid of tools. Alternatively, the first limiting part 1231 and the second limiting part 1232 can be separated and assembled with the sixth limiting structure 4 with the aid of tools.

[0093] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the front panel 12 has a sliding structure 123 that slides and cooperates with the sixth limiting structure 4. The sliding structure 123 includes a sliding groove 1233 or a slider. The first limiting part 1231 and the second limiting part 1232 are spaced apart on the sliding structure 123 along the sliding direction of the sixth limiting structure 4.

[0094] The front panel 12 has a sliding structure 123, and the sixth limiting structure 4 slides in conjunction with the sliding structure 123. The sliding structure 123 can limit the movement of the sixth limiting structure 4, which can improve the stability of the movement of the sixth limiting structure 4 relative to the front panel 12 and reduce the possibility of the sixth limiting structure 4 shifting.

[0095] The sliding structure 123 includes a sliding groove 1233 or a slider. Correspondingly, the sixth limiting structure 4 includes a sliding block that cooperates with the sliding groove 1233 or a sliding groove that cooperates with the slider. The sixth limiting structure 4 and the sliding structure 123 are stably slidably engaged.

[0096] The first limiting part 1231 and the second limiting part 1232 are disposed on the sliding structure 123. The first limiting part 1231 and the second limiting part 1232 are spaced apart along the sliding direction of the sixth limiting structure 4. In this way, when the sixth limiting structure 4 slides to the position of the first limiting structure 31, the sixth limiting structure 4 engages with the first limiting part 1231 and is stabilized in the locked position. When the sixth limiting structure 4 slides to the position of the second limiting structure 121, the sixth limiting structure 4 disengages from the first limiting structure 31 and engages with the second limiting structure 121, and is stabilized in the unlocked position.

[0097] When the sixth limiting structure 4 slides along the sliding structure 123, it can cooperate with the first limiting part 1231 or the second limiting part 1232. The movement of the sixth limiting structure 4 is simple, reliable and easy to operate.

[0098] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the sixth limiting structure 4 has an elastic buckle 41, the first limiting part 1231 and the second limiting part 1232 are respectively formed as slots, and the elastic buckle 41 is adapted to limit and cooperate with the slot.

[0099] The sixth limiting structure 4 has an elastic buckle 41, which can produce elastic deformation. When the sixth limiting structure 4 slides to the position of the first limiting part 1231, the elastic buckle 41 is fixed in the slot in its original state, and the sixth limiting structure 4 can no longer slide, thereby limiting the sixth limiting structure 4 to the first limiting part 1231.

[0100] Simply drive the elastic buckle 41 to generate elastic deformation and remove the elastic buckle 41 from the slot to release the limiting engagement between the sixth limiting structure 4 and the first limiting part 1231, and the sixth limiting structure 4 can continue to slide.

[0101] Similarly, when the sixth limiting structure 4 slides to the position of the second limiting part 1232, the elastic buckle 41 is in the original limiting engagement in the slot, and the sixth limiting structure 4 is in the limiting engagement with the second limiting part 1232.

[0102] The sixth limiting structure 4 forms an elastic buckle 41 that engages with the slot. During the movement of the sixth limiting structure 4, it can automatically complete the limiting engagement by utilizing its own elastic properties, without the need for manual driving to deform. It is convenient to use and easy to operate.

[0103] In some embodiments of this utility model, such as Figure 11 As shown, the sliding structure 123 includes a sliding groove 1233, and a guide groove 1234 communicating with the sliding groove 1233 is formed on the peripheral side wall of the sliding groove 1233. The sixth limiting structure 4 has a sliding engagement part 42 and a guide part 43. The sliding engagement part 42 is slidably engaged with the sliding groove 1233, and the guide part 43 is slidably engaged with the guide groove 1234.

[0104] The sliding structure 123 includes a sliding groove 1233, and the sixth limiting structure 4 has a sliding mating part 42. The sliding mating part 42 is mated with the sliding groove 1233, which can limit the movement of the sixth limiting structure 4 and improve the stability of the movement of the sixth limiting structure 4 relative to the front panel 12.

[0105] Furthermore, a guide groove 1234 communicating with the slide groove 1233 is formed on the peripheral wall of the slide groove 1233. The sixth limiting structure 4 also has a guide part 43, which slides and cooperates with the guide groove 1234 to further limit the movement of the sixth limiting structure 4. The guide groove 1234 is provided on the peripheral wall of the slide groove 1233. The cooperation between the guide groove 1234 and the guide part 43 can also reduce the swaying of the sixth limiting structure 4 in the width direction of the guide groove 1234 and improve the movement stability of the sixth limiting structure 4 relative to the sliding structure 123.

[0106] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, a guide groove 1234 is provided on the rear side wall of the slide groove 1233. The guide part 43 is connected to the sliding mating part 42. At least a part of the guide part 43 passes through the guide groove 1234, which can further limit the sliding of the sixth limiting structure 4 and improve the movement stability of the sixth limiting structure 4.

[0107] In some embodiments of this utility model, such as Figure 8 , Figure 9 and Figure 11 As shown, elastic buckles 41 are provided on both sides of the sliding mating part 42 in the width direction. The first limiting part 1231 and the second limiting part 1232 are respectively constructed as slots on the inner wall of the sliding groove 1233, and the slots are recessed outward relative to the inner wall of the sliding groove 1233.

[0108] When the sliding engagement part 42 moves along the slide groove 1233, the elastic buckles 41 on both sides of the sliding engagement part 42 are limited by the inner wall of the slide groove 1233 and elastically deformed in the direction of the sliding engagement part 42. When the sliding engagement part 42 moves to the position of the first limiting part 1231 or the second limiting part 1232, the elastic buckles 41 return to their original shape under the action of elastic force. The elastic buckles 41 extend into the slot to engage with the slot, thereby restricting the sliding of the sliding engagement part 42.

[0109] In some embodiments of this utility model, such as Figure 11 As shown, the sixth limiting structure 4 also has an operation part 44, which is connected to the end of the guide part 43 away from the sliding mating part 42 and is located outside the slide groove 1233. The operation part 44 is configured such that operating the operation part 44 can move the sixth limiting structure 4 between the locked state and the unlocked state.

[0110] The operating part 44 is located outside the slide groove 1233, which facilitates direct operation of the operating part 44 from the outside and improves ease of use.

[0111] In some embodiments of this utility model, such as Figure 11 As shown, the operating part 44 is provided with multiple raised ribs at intervals, which can increase the surface friction of the operating part 44 and facilitate the operation of the operating part 44.

[0112] In some embodiments of this utility model, a fourth limiting structure 122 is also formed on the peripheral sidewall of the slide groove 1233, and the air outlet grille 3 has a third limiting structure 32. The third limiting structure 32 and the fourth limiting structure 122 can be separated and matched in the front-back direction, and when the two are matched, the fourth limiting structure 122 can restrict the third limiting structure 32 from moving downward.

[0113] When the third limiting structure 32 and the fourth limiting structure 122 work together, the third limiting structure 32 can be restricted from moving downward, that is, the air outlet grille 3 can be restricted from moving downward, and the air outlet grille 3 can be supported, thus improving the arrangement stability of the air outlet grille 3.

[0114] The fourth limiting structure 122 is formed on the sliding groove 1233 of the sliding structure 123 that slides in conjunction with the sixth limiting structure 4, which can improve the structural compactness and reduce the occupation of external space.

[0115] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the sixth limiting structure 4 can move up and down relative to the front panel 12, and the height position of the sixth limiting structure 4 in the locked state is lower than its height position in the unlocked state.

[0116] The height position of the sixth limiting structure 4 in the locked state is lower than the height position of the sixth limiting structure 4 in the unlocked state. In this way, the sixth limiting structure 4 can be stably positioned in the locked state under the action of gravity, which can improve the stability of the sixth limiting structure 4 in the locked state and improve the stability of the fit between the air vent grille 3 and the front panel 12.

[0117] In some embodiments of this utility model, such as Figure 7 As shown, the housing 1 also includes a face frame 13, an air outlet 11 formed on the face frame 13, a front panel 12 covering the front side of the face frame 13, the upper end of the front panel 12 being rotatably connected to the face frame 13, and the lower end of the front panel 12 being detachably connected to the face frame 13. The sixth limiting structure 4 has an operating part 44, which is configured to allow the sixth limiting structure 4 to move between a locked state and an unlocked state. The operating part 44 is exposed on the back side of the front panel 12.

[0118] The upper end of the front panel 12 is rotatably connected to the face frame 13, and the lower end of the front panel 12 is detachably connected to the face frame 13. When the lower end of the front panel 12 is connected to the face frame 13, the front panel 12 stably covers the front side of the face frame 13. When the lower end of the front panel 12 is detached from the face frame 13, the lower end of the front panel 12 can be driven to flip forward relative to the face frame 13 with the upper end of the front panel 12 as the axis.

[0119] By detachably connecting the lower end of the front panel 12 to the front frame 13, the front panel 12 can be easily flipped open to expose the structure on the rear side of the front frame 13, thus facilitating subsequent maintenance of the air conditioner 100. Furthermore, the air vent grille 3 is connected to the lower end of the front panel 12 and is detachably connected to it. Flipping the front panel 12 forward increases the operating space for assembling and disassembling the air vent grille 3 from the front panel 12, making operation easier.

[0120] The sixth limiting structure 4 has an operating part 44. By flipping open the front panel 12, a certain distance can be created between the back side of the front panel 12 and the face frame 13, thus providing operating space for operating the operating part 44. For example, by flipping open the front panel 12 to open the back side of the front panel 12 forward, the operating part 44 located on the back of the front panel 12 can be exposed, facilitating direct operation of the operating part 44 from the outside and improving ease of use.

[0121] By rotating the upper end of the front panel 12 to the face frame 13, the front panel 12 does not need to be removed from the face frame 13 as a whole, which makes operation more convenient.

[0122] In some embodiments of this utility model, such as Figure 7 and Figure 13As shown, a support structure 14 is provided between the front frame 13 and the front panel 12. When the front panel 12 is opened relative to the front frame 13, the support structure 14 is adapted to support between the front frame 13 and the front panel 12 so that the front panel 12 is maintained at a predetermined opening angle. This application does not limit the predetermined opening angle; for example, the predetermined opening angle can be an acute angle, a right angle, or an obtuse angle.

[0123] The upper end of the front panel 12 is rotatably connected to the panel. By setting the support structure 14, the front panel 12 can be supported by the support structure 14 when it is rotated open relative to the face frame 13, keeping the front panel 12 at a predetermined opening angle. Users do not need to apply force to keep the front panel 12 in the open position, which frees up their hands and facilitates the subsequent maintenance and replacement of the air conditioner 100, or the disassembly and assembly of the air outlet grille 3.

[0124] In some embodiments of this utility model, such as Figure 7 and Figure 12 As shown, the support structure 14 is configured as a support member rotatably connected to the front panel 12 or the face frame 13. When the front panel 12 is opened relative to the face frame 13, the support member supports the face frame 13, thereby holding the front panel 12 at a predetermined opening angle. Of course, the support member can also be detachably connected to the front panel 12 / face frame 12.

[0125] In some embodiments of this utility model, such as Figure 12 As shown, the support structure 14 includes a first limiting block 131 and a second limiting hole 124. The first limiting block 131 is disposed on the face frame 13, and the second limiting block 124 is disposed on the front panel 12. When the front panel 12 is rotated to a predetermined angle, the first limiting block 131 is adapted to stop the second limiting block 124 so that the opening angle of the front panel 12 is maintained at the predetermined angle.

[0126] When the front panel 12 is opened relative to the face frame 13, the second limiting block 124 moves together with the front panel 12 relative to the face frame 13. When the front panel 12 rotates to a predetermined angle, the first limiting block 131 stops below the second limiting block 124, thereby stopping the second limiting block 124 and preventing the front panel 12 from falling back under the action of gravity, so that the front panel 12 remains open at a predetermined angle.

[0127] In some embodiments of this utility model, such as Figure 7 and Figure 12 As shown, the front panel 12 has a support arm, which is rotatably connected to the face frame 13. A second limiting block 124 is provided on the support arm. When the front panel 12 is opened relative to the face frame 13, the second limiting block 124 on the support arm also moves together. When the front panel 12 is rotated to a predetermined angle, the second limiting block 124 is stopped by the first limiting block 131, thereby keeping the front panel 12 at the predetermined angle.

[0128] In some embodiments of this utility model, such as Figure 1 As shown, the first air outlet area 11a is formed on the bottom side of the housing 1, and the second air outlet area 11b is formed on the front side of the housing 1. The front end of the first air guide plate 2 is adapted to cooperate with the lower end of the air outlet grille 3 to close the first air outlet area 11a.

[0129] The first air outlet area 11a is formed on the bottom side of the housing 1. When airflow flows from the first air outlet area 11a, the first air guide plate 2 can guide the airflow in and out. For example, the first air guide plate 2 guides the airflow forward, which can increase the forward delivery distance of the airflow, and can also lift the airflow from the second air outlet area 11b, thereby increasing the forward flow distance of the airflow; for another example, the first air guide plate 2 guides the airflow downward, pressing down the airflow from the first air outlet area 11a located on the bottom side of the housing 1, which is beneficial for heating airflow, and can deliver hot air to the foot area. The hot air diffuses and heats up from bottom to top, which can greatly improve the heating temperature rise effect and make the stratification more uniform.

[0130] The second air outlet area 11b is formed on the front side of the housing 1. The air outlet grille 3 can be used to guide the airflow from the second air outlet area 11b. Furthermore, when the first air guide plate 2 covers the first air outlet area 11a, the second air outlet area 11b can also emit air, and the airflow blows forward, which can reduce the discomfort of direct airflow to the human body and achieve the function of preventing direct airflow.

[0131] The first air outlet area 11a is formed on the bottom side of the housing 1, and the second air outlet area 11b is formed on the front side of the housing 1. The air outlet 11 has a large coverage area, which can increase the air sweep range of the air conditioner 100 and improve the air heat exchange effect.

[0132] The front end of the first air guide plate 2 engages with the lower end of the air outlet grille 3, and there are no other structural obstructions between the first air outlet area 11a and the second air outlet area 11b, which reduces airflow resistance. Airflow can flow smoothly between the first air outlet area 11a and the second air outlet area 11b, improving airflow fluidity.

[0133] In some embodiments of this utility model, such as Figure 10 and Figure 13As shown, the front panel 12 includes an outer panel 12a and an inner panel 12b. The outer panel 12a covers a portion of the front side of the inner panel 12b. The front side of the inner panel 12b is provided with a mounting groove 125. The bottom wall of the mounting groove 125 has a hollow area 126. The hollow area 126 extends in a long strip shape in the left and right direction. The length L1 of the hollow area 126 is less than the length L2 of the inner panel 12b. The hollow area 126 penetrates the lower end of the mounting groove 125 and is directly opposite the second air outlet area 11b. The outer panel 12a and the air outlet grille 3 are both provided in the mounting groove 125. The air outlet grille 3 is located on the lower side of the outer panel 12a and covers the hollow area 126. The left and right ends of the air outlet grille 3 are detachably fitted to the portions of the inner panel 12b located at both ends of the hollow area 126. The upper end of the air outlet grille 3 is detachably fitted to the rear side of the inner panel 12b through the through hole 127 on the front panel 12.

[0134] The inner panel 12b has a larger coverage area than the outer panel 12a. The outer panel 12a covers part of the front side of the inner panel 12b. By providing a hollow area 126 at the lower end of the front side of the inner panel 12b, the air outlet of the second air outlet area 11b can be avoided, thereby improving airflow.

[0135] The inner panel 12b has a mounting groove 125 on its front side. Both the outer panel 12a and the air outlet grille 3 are located in the mounting groove 125, which improves the installation stability of the outer panel 12a and the inner panel 12b, as well as the connection stability between the air outlet grille 3 and the inner panel 12b. Figure 3 As shown, the air vent grille 3 is connected to the lower side of the outer panel 12a, which can improve the integrity of the air vent grille 3 and the front panel 12, and improve the integrity of the front side of the air conditioner 100.

[0136] The left and right ends of the air outlet grille 3 can be detachably fitted to the parts of the inner panel 12b located at both ends of the hollow area 126. The fit between the air outlet grille 3 and the front panel 12 has little impact on the wind resistance of the air outlet 11, which is conducive to improving the airflow smoothness of the air conditioner 100.

[0137] The upper end of the air vent grille 3 is detachably fitted to the rear side of the inner panel 12b through the through hole 127 on the front panel 12. The upper end of the air vent grille 3 extends into the rear side of the front panel 12, thereby restricting the movement of the air vent grille 3 relative to the front panel 12 in the front-rear direction and improving the stability of the fit between the air vent grille 3 and the front panel 12.

[0138] The outer panel 12a and the inner panel 12b can be integrally molded, which can improve the integrity of the front panel 12; the outer panel 12a and the inner panel 12b can also be separate molded parts and assembled together, which can reduce the manufacturing difficulty.

[0139] In some embodiments of this utility model, the color of the air vent grille 3 is different from the color of the front panel 12.

[0140] Understandably, the grille-like structure of the air vent grille 3 is prone to accumulating dust. Therefore, the color of the air vent grille 3 can be set to a darker color, or a color similar to the color of dust, to reduce visual discomfort.

[0141] Furthermore, by designing the color of the air vent grille 3 to be different from the color of the front panel 12, the difference between the air vent grille 3 and the front panel 12 is greater, making it easier to remove the air vent grille 3 from the front panel 12.

[0142] In some embodiments of this utility model, such as Figure 5 and Figure 13 As shown, the air outlet grille 3 includes a first air guide rib 34 and a second air guide rib 35. There are multiple first air guide ribs 34 and they are spaced apart in the vertical direction. Each first air guide rib 34 extends in the horizontal direction. The second air guide rib 35 intersects with the multiple first air guide ribs 34. The front end of the first air guide rib 34 protrudes forward beyond the front end of the second air guide rib 35.

[0143] The air outlet grille 3 includes intersecting first air guide ribs 34 and second air guide ribs 35, which can improve the structural stability of the air outlet grille 3, reduce the shaking of the air outlet grille 3 under the impact of airflow, and reduce the air outlet noise.

[0144] The front end of the first air guide rib 34, which extends in the left and right directions, protrudes forward beyond the front end of the second air guide rib 35. The first air guide rib 34 has a better effect on guiding the airflow forward and can improve the airflow effect.

[0145] In some embodiments of this utility model, the surface hot stamping of the first air guide rib 34 and the second air guide rib 35 can be single color hot stamping or multiple colors can be hot stamped in different areas to meet different appearance change requirements.

[0146] The following description, with reference to the accompanying drawings, illustrates the structure and disassembly process of the air outlet grille 3 relative to the front panel 12 in a specific embodiment of the present invention.

[0147] The air outlet grille 3 has a first limiting structure 31, a third limiting structure 32 and a fifth limiting structure 33, wherein the first limiting structure 31 is located at the upper end of the air outlet grille 3, the fifth limiting structure 33 is located at the lower end of the air outlet grille 3, and the third limiting structure 32 is located below the first limiting structure 31 and above the fifth limiting structure 33.

[0148] Correspondingly, a second limiting structure 121, a fourth limiting structure 122, and a sixth limiting structure 4 are formed or arranged on the front panel 12. The second limiting structure 121 is used to limit and cooperate with the first limiting structure 31, the fourth limiting structure 122 is used to limit and cooperate with the third limiting structure 32, and the sixth limiting structure 4 is used to limit and cooperate with the fifth limiting structure 33.

[0149] The first limiting structure 31 has a hanging groove 311 with its opening facing forward. A through hole 127 is provided on the front panel 12. The first lower limiting structure extends from front to back through the through hole 127 to the rear side of the front panel 12. The second limiting structure 121 is positioned above the through hole 127 and on the front side of the front panel 12. When the first limiting structure 31 passes through the through hole 127 from top to bottom and from front to back, it allows the second limiting structure 121 to be accommodated from the front into the hanging groove 311, thus completing the hook-and-loop engagement of the first limiting structure 31 and the second limiting structure 121. When the first limiting structure 31 and the second limiting structure 121 are engaged, the second limiting structure 121 can restrict the downward and forward movement of the first limiting structure 31.

[0150] The third limiting structure 32 and the fourth limiting structure 122 are detachable and can be engaged in the front-to-back direction. When engaged, the fourth limiting structure 122 can restrict the downward movement of the third limiting structure 32. There are multiple third limiting structures 32, which are spaced apart in the vertical direction. One third limiting structure 32 has a first limiting groove 321 with its opening facing backward, and another third limiting structure 32 has a second limiting protrusion 322 that protrudes backward. The first limiting groove 321 is located above the second limiting protrusion 322. Correspondingly, a fourth limiting structure 122 is formed as a first limiting protrusion 1221 that protrudes forward and extends into the first limiting groove 321. The fourth limiting structure 122 is formed with a limiting hole 1222 into which the second limiting protrusion 322 can extend. The first limiting protrusion 1221 is located above the limiting hole 1222. Thus, the cooperation between the third limiting structure 32 and the fourth limiting structure 122 forms an interlocking structure in the vertical direction, which can improve the stability of the cooperation between the air vent grille 3 and the front panel 12.

[0151] The fifth limiting structure 33 forms a second limiting groove 331 with the opening facing upward, while the sixth limiting structure 4 is movably arranged on the front panel 12. The sixth limiting structure 4 has a locked state and an unlocked state. In the locked state, the sixth limiting structure 4 extends into the second limiting groove 331, and in the unlocked state, the sixth limiting structure 4 disengages from the second limiting groove 331.

[0152] When removing the air vent grille 3 from the front panel 12, firstly, move the sixth limiting structure 4 from the locked state to the unlocked state, allowing the bottom of the air vent grille 3 to move. Next, rotate the air vent grille 3 forward relative to the front panel 12 by more than a preset angle, using the top as the rotation center. During this process, not only does the third limiting structure 32 move forward to disengage from the fourth limiting structure 122, but the first limiting structure 31 also moves backward relative to the second limiting structure 121, allowing the second limiting structure 121 to move out of the hanging slot 311 and releasing the engagement between the first limiting structure 31 and the second limiting structure 121. Finally, pass the top of the air vent grille 3 from back to front through the through hole 127 to remove the air vent grille 3 from the front panel 12.
