The second fixing device passes through the base 110 and the corresponding second air outlet frame insert 122 in sequence to fix the base 110 and the air outlet frame 120 together.

[0045] In the indoor unit 100 of this air conditioner, the positioning of the air outlet frame 120 on the base 110 is facilitated by the cooperation of the first air outlet frame insert 121 and the first air outlet frame socket 113, and the cooperation of the second air outlet frame insert 122 and the second air outlet frame socket 114. Furthermore, the first fixing device simultaneously fixes the liner 130 and the air outlet frame 120 to the base 110, simplifying the installation process of the air outlet frame 120 and the liner 130, improving installation efficiency, and reducing the number of first fixing devices. Further, the second fixing device fixes the air outlet frame 120 to the base 110, making the installation of the air outlet frame 120 more secure.

[0046] In some embodiments of this utility model, both the first fixing device and the second fixing device are screws. Screws make the connection between the liner 130, the air outlet frame 120 and the base 110 more secure, and also facilitate quick connection and disassembly.

[0047] In some embodiments of this utility model, such as Figure 4 As shown, a plurality of hooks 132 are provided on the rear surface of the liner 130, and the hooks 132 are hung on the air outlet frame 120. A mounting groove 115 is provided on the base 110, extending forward and upward through the base 110, and a connector 131 is inserted into the mounting groove 115. A groove cover 140 is provided at the front opening of the mounting groove 115. The groove cover 140 can be installed at the front opening of the mounting groove 115 via a snap-fit ​​151.

[0048] In this embodiment, during installation, the liner 130 is first hung on the air outlet frame 120 using hooks 132. Simultaneously, the connector 131 of the liner 130 is inserted into the mounting groove 115 through its upper opening. Then, the first fixing device is inserted through the front opening of the mounting groove 115 to fix the liner 130 to the base 110. Since the first fixing device is a screw, to maintain the aesthetics of the indoor unit 100 and prevent users from directly seeing the screws on the front of the indoor unit 100, a cover 140 is provided to conceal the screws, achieving an aesthetic effect.

[0049] Furthermore, the liner 130 is not only connected to the air outlet frame 120 via the hook 132, but is also fixed to the base 110 together with the air outlet frame 120 via screws. This arrangement can prevent the liner 130 from being too heavy and causing the indoor unit 100 of the air conditioner to tilt forward, thereby improving the stability of the indoor unit 100 of the air conditioner.

[0050] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the indoor unit 100 of the air conditioner also includes an air inlet grille 150 and a third fixing device. The air inlet grille 150 is located on the rear side of the air outlet frame 120. A buckle 151 and an air inlet grille insert 152 are provided on the lower side of the air inlet grille 150. A locking hole 116 and an air inlet grille insertion hole 117 are provided on the base 110. The buckle 151 engages with the locking hole 116. The air inlet grille insert 152 is inserted into the air inlet grille insertion hole 117. The third fixing device passes sequentially through the base 110 and the air inlet grille insert 152 from the lower side of the base 110, fixing the base 110 and the air inlet grille 150 together.

[0051] In this embodiment, airflow enters the indoor unit 100 of the air conditioner through the air inlet grille 150, forms a heat exchange airflow after a heat exchange process, and flows out from the air outlet frame 120. The installation process of the air inlet grille 150 is as follows: the air inlet grille 150 is moved downward so that the clip 151 on the lower side of the air inlet grille 150 engages with the clip hole 116 on the base 110. At the same time, the air inlet grille insert 152 is also inserted into the air inlet grille insertion hole 117 on the base 110. Then, the third fixing device passes through the base 110 and the air inlet grille insert 152 from the lower side of the base 110 to fix the base 110 and the air inlet grille 150 together. The third fixing device can also be a screw.

[0052] The pre-fixation of the air intake grille 150 is achieved by the engagement of the clip 151 on the air intake grille 150 with the locking hole 116 on the base 110, preventing the air intake grille 150 from moving during installation and thus facilitating its installation. Furthermore, the engagement of the clip 151 with the locking hole 116, the engagement of the air intake grille insert 152 with the air intake grille insertion hole 117, and the engagement of the third fixing device with the base 110 and the air intake grille insert 152, together achieve a secure connection between the air intake grille 150 and the base 110, making the connection more robust.

[0053] In some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 7 As shown, the indoor unit 100 of the air conditioner also includes a trim strip 160, which includes a front trim strip segment and two side trim strip segments connected to both ends of the front trim strip segment. The trim strip 160 is snapped onto the edge of the base 110. The front trim strip segment is located on the underside of the liner 130.

[0054] In this embodiment, the decorative strip 160 makes the indoor unit 100 of the air conditioner more aesthetically pleasing, enhancing its visual appeal. The decorative strip 160 can be manufactured using an electroplating process. The decorative strip 160 is snap-fitted to the base 110, making installation more convenient.

[0055] In some embodiments of this utility model, such as Figure 3 As shown, the base 110 also includes a bottom support portion 111 and an upper support portion 112 connected to the upper side of the bottom support portion 111. The connection between the outer peripheral wall of the upper support portion 112 and the bottom support portion 111 is spaced apart from the edge of the upper surface of the bottom support portion 111. That is, in the horizontal direction, the area of ​​the bottom support portion 111 is larger than the area of ​​the upper support portion 112. This arrangement makes the contact area between the base 110 and the ground larger, thereby making the indoor unit 100 of the air conditioner more stable and less prone to tilting.

[0056] The air outlet frame 120, the liner 130, and the air inlet grille 150 are mounted on the upper support portion 112. The upper support portion 112 provides good support for the air outlet frame 120, the liner 130, and the air inlet grille 150. The decorative strip 160 is located at the edge of the upper surface of the bottom support portion 111 and provides a good decorative effect for the base 110.

[0057] In some embodiments of this utility model, a clearance space is provided at the edge of the upper surface of the bottom support 111, and the decorative strip 160 is disposed in the clearance space. This arrangement allows the upper surface of the decorative strip 160 to smoothly transition with the upper surface of the bottom support 111, and the side surface of the decorative strip 160 to be flush with the side surface of the bottom support 111, thereby improving the integration of the decorative strip 160 with the base 110 and preventing the decorative strip 160 from appearing too abrupt on the base 110.

[0058] In some embodiments of this utility model, such as Figure 7 As shown, the trim strip 160 includes a trim strip body 161 and a plurality of hooks 162 disposed at the bottom of the trim strip body 161. Each hook 162 includes a support strip and a hook portion disposed at the bottom end of the support strip. A slot for inserting the hook 162 is provided on the bottom wall of the clearance space, and a stop block for preventing the hook portion from being pulled out of the slot is provided on the side wall of the slot.

[0059] In this embodiment, during the installation of the trim strip 160, the multiple hooks 162 of the trim strip 160 are respectively aligned with each slot. The trim strip 160 is pressed downwards, and the hooks 162 are inserted into the corresponding slots. As the hooks 162 move downwards, they undergo a certain elastic deformation until the hook portion of the hook 162 reaches the lower part of the stop block. At this point, the hooks 162 return to their elastic deformation, forming a stop engagement with the stop block. In this embodiment, the trim strip 160 and the base 110 are quickly and securely installed through the cooperation of the hooks 162 and the stop block.

[0060] In some embodiments of this utility model, such as Figure 2 As shown, the liner 130 extends forward beyond the upper support portion 112, so that the liner 130, the upper support portion 112, and the bottom support portion 111 form a groove. In this embodiment, the structure of the groove makes the shape of the air conditioner indoor unit 100 unique and more aesthetically pleasing. Furthermore, the groove cover 140 in the above embodiment is located within the groove, making the groove cover 140 less likely to be observed, further enhancing the aesthetics of the air conditioner indoor unit 100.

[0061] In some embodiments of this utility model, such as Figure 3 As shown, the base 110 has two mounting positions 1171 for mounting a third fixing device at positions corresponding to one or more air inlet grille holes 117. At least one mounting position 1171 is provided with a third fixing device.

[0062] In this embodiment, by providing two mounting positions 1171 at the corresponding locations of the air inlet grille insertion hole 117, the air inlet grille insertion hole 117 and the corresponding air inlet grille insert 152 can be fixed by two third fixing devices, making the connection between the air inlet grille 150 and the base 110 more secure. Of course, each air inlet grille insertion hole 117 and the corresponding air inlet grille insert 152 can also be connected by only one third fixing device.

[0063] In some embodiments of this utility model, such as Figure 3As shown, at least one second air outlet frame socket 114 includes a first space and a second space that are interconnected, the depth of the first space being less than the depth of the second space. The corresponding second air outlet frame insert 122 includes a first insertion part and a second insertion part, the first insertion part being connected to the second insertion part, the first insertion part being inserted into the first space, and the second insertion part being inserted into the second space.

[0064] In this embodiment, since the first insertion part is inserted into the first space and the second insertion part is inserted into the second space, the fit between the second air outlet frame insert 122 and the second air outlet frame socket 114 is tighter, thereby making the connection between the air outlet frame 120 and the base 110 more stable.

[0065] In some embodiments of this utility model, air outlets are provided on both sides of the air outlet frame 120, and each air outlet extends vertically. In this embodiment, by providing two lateral air outlets, the heat exchange airflow can be blown out to both sides, which not only expands the airflow range but also prevents cold air from blowing directly out.

[0066] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
