Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] First Embodiment

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides an indoor unit 100, which can improve the vibration of the panel 120 relative to the middle frame 110, reduce the noise of the indoor unit 100 during operation, and improve the user experience.

[0032] The indoor unit 100 is mainly used in air conditioners and is installed indoors. During operation, the indoor unit 100 should operate as smoothly as possible to reduce noise. The indoor unit 100 includes a middle frame 110 and a panel 120, with the panel 120 mounted on the middle frame 110. Due to poor fixing between the two, vibrations and abnormal noises may occur during operation, affecting the user experience. The indoor unit 100 provided in this embodiment improves the above problems by enhancing the fixing effect between the middle frame 110 and the panel 120, reducing abnormal noises during operation, and improving the user experience.

[0033] In this embodiment, the indoor unit 100 includes a middle frame 110 and a panel 120. The middle frame 110 has a mounting groove 111. The panel 120 includes a panel body 121, a fixing part 122 and a supporting part 123. The fixing part 122 is connected to the panel body 121, and the supporting part 123 is connected to the fixing part 122. Both the fixing part 122 and the supporting part 123 are disposed in the mounting groove 111, and both the fixing part 122 and the supporting part 123 abut against the mounting groove 111.

[0034] In this embodiment, the mounting groove 111 on the middle frame 110 is mainly used to cooperate with the fixing part 122 on the upper part of the panel 120 to realize the positioning between the middle frame 110 and the panel 120. For ease of installation, the size of the mounting groove 111 is usually larger than the size of the fixing part 122. During the operation of the indoor unit 100, due to the allowance between the fixing part 122 and the mounting groove 111, the panel 120 may vibrate relative to the middle frame 110. The abutment part 123 is installed on the fixing part 122. During the cooperation between the fixing part 122 and the mounting groove 111, the fixing part 122 can abut against the groove wall of the mounting groove 111, reducing the gap between the fixing part 122 and the mounting groove 111, improving the vibration of the panel 120 relative to the middle frame 110, reducing the noise of the indoor unit 100 during operation, and improving the user experience.

[0035] In this embodiment, the fixing part 122 and the supporting part 123 are disposed in the mounting groove 111 and both abut against the groove wall of the mounting groove 111, thereby reducing the gap between the fixing part 122 and the supporting part 123 and the mounting groove 111, reducing the shaking of the panel 120 relative to the middle frame 110, reducing the noise of the indoor unit 100 during operation, and improving the user experience.

[0036] In this embodiment, the mounting groove 111 is elongated, and the fixing part 122 is also elongated. The fixing part 122 is disposed within the mounting groove 111. To save manufacturing costs, the length of the supporting part 123 is relatively short. To improve the supporting effect of the supporting part 123, multiple supporting parts 123 can be provided, which are spaced apart on the fixing part 122. The multiple supporting parts 123 abut against the fixing part 122 from different positions, reducing the gap between the fixing part 122 and the mounting groove 111 at different positions, and improving the fixing effect between the fixing part 122 and the mounting groove 111.

[0037] As for the number of supporting parts 123, it can be set according to the length of the fixing part 122. The longer the length of the fixing part 122, the more supporting parts 123 can be set.

[0038] Please see Figure 4 and Figure 5In this embodiment, the middle frame 110 includes a middle frame body 112, a first mounting part 113 and a second mounting part 114. The first mounting part 113 and the second mounting part 114 are spaced apart on the middle frame body 112. The first mounting part 113, the second mounting part 114 and the middle frame body 112 form a mounting groove 111. The side of the fixing part 122 away from the abutting part 123 abuts against the first mounting part 113, and the side of the abutting part 123 away from the fixing part 122 abuts against the second mounting part 114.

[0039] In this embodiment, the first mounting part 113 and the second mounting part 114 are spaced apart. When the indoor unit 100 is in operation, the first mounting part 113 is located below the second mounting part 114. When the fixing part 122 and the supporting part 123 are accommodated in the mounting groove 111, the fixing part 122 abuts against the first mounting part 113 located below, and the supporting part 123 abuts against the second mounting part 114 located above.

[0040] In this embodiment, the second mounting part 114 has a mounting surface 1142 on the side near the supporting part 123, and the supporting part 123 has a supporting surface 1232 on the side away from the fixing part 122. The mounting surface 1142 and the supporting surface 1232 are adapted to each other.

[0041] With the fixing part 122 and the supporting part 123 installed in the mounting groove 111, the supporting surface 1232 and the mounting surface 1142 cooperate and support each other. Their shapes are compatible, and with the supporting part 123 installed in the mounting groove 111, the supporting surface 1232 and the mounting surface 1142 fit together, reducing the gap between the supporting part 123 and the second mounting part 114, reducing the vibration of the panel 120 relative to the middle frame 110, improving the fixing effect of the fixing part 122 and the mounting groove 111, reducing the noise of the indoor unit 100 during operation, and improving the user experience.

[0042] To facilitate the cooperation between the fixing part 122 and the mounting groove 111, the abutment surface 1232 is inclined. During the installation of the middle frame 110, the fixing part 122 is first placed at the opening of the mounting groove 111, and then the panel 120 is pushed towards the bottom of the mounting groove 111. The abutment surface 1232 gradually abuts against the mounting surface 1142 and slides relative to the mounting surface 1142. Due to the inclined setting of the abutment surface 1232, the total height of the fixing part 122 and the abutment part 123 in the mounting groove 111 gradually increases, and the fixing part 122 gradually abuts against the first mounting part 113. Finally, the fixing part 122 abuts against the first mounting part 113, and the abutment part 123 abuts against the second mounting part 114.

[0043] In addition, in order to improve the fixing effect between the panel 120 and the middle frame 110, in addition to the cooperation between the fixing part 122 and the mounting groove 111, a first fastener 115 is provided to cooperate with the first fastener 124, and a second fastener 116 is provided to cooperate with the second fastener 125.

[0044] In this embodiment, the middle frame 110 includes a middle frame body 112, a first fastener 115 and a second fastener 116, and the panel 120 includes a panel body 121, a first holding member 124 and a second holding member 125. The first holding member 124 cooperates with the second fastener 116, and the second holding member 125 cooperates with the second fastener 116. The first fastener 115 and the second fastener 116 are set at an angle, and the first holding member 124 and the second holding member 125 are set at an angle.

[0045] In this embodiment, the first latching member 115 and the second latching member 116 are set at an angle, and correspondingly, the first holding member 124 and the second holding member 125 are set at an angle. The first latching member 115 and the first holding member 124 fix the panel 120 and the middle frame 110 from one direction, and the second latching member 116 and the second holding member 125 fix the panel 120 and the middle frame 110 from the other direction. The panel 120 and the middle frame 110 are limited from two different directions, which improves the fixing effect of the panel 120 and the middle frame 110.

[0046] Preferably, the first latching member 115 and the second latching member 116 are perpendicular to each other, the first holding member 124 and the second holding member 125 are perpendicular to each other, the extending direction of the first latching member 115 is perpendicular to the extending direction of the mounting groove 111, and the extending direction of the second latching member 116 is the same as the extending direction of the mounting groove 111. For ease of description, the direction parallel to the extending direction of the mounting groove 111 is defined as the first direction, and the direction perpendicular to the extending direction of the mounting groove 111 is defined as the second direction. The third direction is perpendicular to both the first and second directions.

[0047] Please see Figure 6 and Figure 7 In this embodiment, the first holding member 124 includes a first connecting section 1241 and a first holding section 1243 connected to each other. The end of the first connecting section 1241 away from the first holding section 1243 is connected to the panel body 121. The first fastener 115 includes a first transition section 1152 and a first fastening section 1154. The first holding section 1243 cooperates with the first fastening section 1154.

[0048] In this embodiment, as the panel 120 gradually approaches the middle frame 110, the first holding segment 1243 slides relative to the first latching segment 1154 until the first holding segment 1243 abuts against each other.

[0049] In this embodiment, the first holding segment 1243 extends along the second direction, and the first connecting segment 1241 extends along the third direction. The first holding segment 1243 cooperates with the first latching segment 1154 to restrict the degree of freedom of the panel 120 in the third direction.

[0050] The first latching section 1154 includes a first guide surface 1156 and a first latching surface 1158, and the first holding section 1243 has a first holding surface 1245 and a first stop surface 1247. After the first holding surface 1245 slides into place relative to the first guide surface 1156, the first stop surface 1247 abuts against the first latching surface 1158.

[0051] In this embodiment, as the panel 120 gradually approaches the middle frame 110, the first holding surface 1245 slides relative to the first guide surface 1156. After the first holding surface 1245 disengages from the first guide surface 1156, the first stop surface 1247 abuts against the first latching surface 1158, restricting the displacement of the panel 120 in the third direction of the mounting groove 111.

[0052] The first holding surface 1245 is inclined, the first stop surface 1247 is perpendicular to the first connecting section 1241, and the first stop surface 1247 abuts against the first buckling surface 1158 when the first holding surface 1245 and the first stop surface 1247 are disengaged.

[0053] In this embodiment, there are two first fasteners 115, and therefore two first holding surfaces 1245. The two first holding surfaces 1245 are arranged opposite to each other, and the two first fasteners 115 are spaced apart to form a holding groove. The first fastening segment 1154 is disposed in the holding groove, and the first fastening segments 1154 of the two first fasteners 115 engage with the first fastening segment 1154 from both sides.

[0054] Meanwhile, the first fasteners 115 are spaced apart in the first direction, and the first fastening segments 1154 of the two first fasteners 115 restrict the position of the holding segment from both sides in the first direction, thereby restricting the degree of freedom of the panel 120 in the first direction.

[0055] It is easy to understand that the two first latch segments 1154 have the same structure and shape, but the installation positions of the two are slightly different. The two first latch segments 1154 are set at intervals, thereby restricting the degree of freedom of the panel 120 in the first direction.

[0056] Please see Figure 8 and Figure 9In this embodiment, the second holding member 125 includes a second connecting section 1252 and a second holding section 1254 that are connected to each other. The end of the second connecting section 1252 away from the second holding section 1254 is connected to the panel body 121. The second fastener 116 includes a second transition section 1162 and a second fastening section 1164. The second holding section 1254 and the second fastening section 1164 cooperate with each other.

[0057] In this embodiment, the second connecting segment 1252 extends along a third direction, and the second holding segment 1254 extends along a first direction. As the panel 120 gradually approaches the middle frame 110, the second holding segment 1254 slides relative to the second latching segment 1164 and abuts against the second latching segment 1164, thus restricting the degree of freedom of the panel 120 in the third direction.

[0058] In this embodiment, the second latching section 1164 includes a second guide surface 1166 and a second latching surface 1168, and the second holding section 1254 has a second holding surface 1256 and a second stop surface 1258. After the second holding surface 1256 slides into place relative to the second guide surface 1166, it abuts against the second latching surface 1168.

[0059] The second guide surface 1166 and the second latching surface 1168 are both inclined in opposite directions. The second guide surface 1166 is located close to the panel 120. The second holding surface 1256 first contacts the second guide surface 1166 and slides relative to the second guide surface 1166 towards the second latching surface 1168. After the second holding surface 1256 disengages from the second guide surface 1166, the second stop surface 1258 abuts against the second latching surface 1168.

[0060] In this embodiment, the middle frame 110 also includes a stop member 117, which is spaced apart from the second latching section 1164. Under the condition that the second holding section 1254 and the second latching section 1164 abut against each other, the stop member 117 abuts against the side of the second holding section 1254 away from the second latching section 1164.

[0061] Among them, the stop member 117 is spaced apart from the second buckle member 116 in the second direction. When the second buckle member 116 and the second holding member 125 cooperate with each other, the stop member 117 and the side of the second holding section 1254 away from the second buckle section 1164 abut against each other, restricting the degree of freedom of the entire panel 120 in the second direction.

[0062] Please see Figure 2 and Figure 3 In this embodiment, the middle frame 110 includes a middle frame body 112 and a limiting rod 118. The limiting rod 118 is connected to the middle frame body 112. The panel 120 is provided with a limiting groove 126, and the limiting rod 118 cooperates with the limiting groove 126.

[0063] In this embodiment, the limiting rod 118 extends along the second direction and cooperates with the limiting groove 126, which can also limit the degree of freedom of the panel 120 in the third direction.

[0064] In this embodiment, the middle frame 110 includes a middle frame body 112 and a support rod 119. The support rod 119 is mounted on the middle frame body 112. The panel 120 also includes a support member 127, which is mounted on the panel body 121 and abuts against the support rod 119.

[0065] The opposing force of the abutment 127 and the abutment rod 119 can also restrict the freedom of the panel 120 in the third direction.

[0066] Furthermore, since the middle frame 110 is relatively long in the first direction, the abutment rod 119 and the limiting rod 118 are spaced apart on the middle frame body 112, which restricts the degree of freedom of different positions of the middle frame 110 in the third direction and improves the fixing effect of the panel 120.

[0067] In this embodiment, the two first latching members 115 cooperate with the first holding member 124 to restrict the degree of freedom of the panel 120 in the first direction. The second latching member 116 and the stop member 117 cooperate with the second holding member 125 to restrict the degree of freedom of the panel 120 in the second direction. The cooperation of the first latching member 115 with the first holding member 124 and the second holding member 125 with the second latching member 116 restricts the degree of freedom of the panel 120 in the third direction away from the middle frame 110. The abutment member 127 abuts against the abutment rod 119 and the limiting rod 118 cooperates with the limiting groove 126 to restrict the degree of freedom of the panel 120 in the third direction towards the middle frame 110. Thus, six degrees of freedom of the panel 120 are restricted.

[0068] The working principle of the indoor unit 100 provided in this embodiment is as follows: In this embodiment, during the installation of the middle frame 110, the fixing part 122 is first set at the groove opening of the mounting groove 111, and then the panel 120 is pushed towards the bottom of the mounting groove 111. The abutting surface 1232 gradually abuts against the mounting surface 1142 and slides relative to the mounting surface 1142. Since the abutting surface 1232 is inclined, the total height of the fixing part 122 and the abutting part 123 in the mounting groove 111 gradually increases, and the fixing part 122 gradually abuts against the first mounting part 113. Simultaneously, the first holding surface 1245 slides relative to the first guide surface 1156. After the first holding surface 1245 disengages from the first guide surface 1156, the first stop surface 1247 abuts against the first latching surface 1158. The second holding surface 1256 first contacts the second guide surface 1166 and slides relative to the second guide surface 1166 towards the second latching surface 1168. When the second holding surface 1256 disengages from the second guide surface 1166, the second stop surface 1258 abuts against the second latching surface 1168. The panel 120 continues to be pushed until the abutting member 127 abuts against the abutting rod 119 and the limiting rod 118 engages with the limiting groove 126.

[0069] In summary, the indoor unit 100 provided in this embodiment has a mounting groove 111 on the middle frame 110, which is mainly used to cooperate with the fixing part 122 on the upper part of the panel 120 to achieve positioning between the middle frame 110 and the panel 120. For ease of installation, the size of the mounting groove 111 is usually larger than the size of the fixing part 122. During the operation of the indoor unit 100, due to the allowance between the fixing part 122 and the mounting groove 111, the panel 120 may vibrate relative to the middle frame 110. The abutment part 123 is installed on the fixing part 122. During the cooperation between the fixing part 122 and the mounting groove 111, the fixing part 122 can abut against the groove wall of the mounting groove 111, reducing the gap between the fixing part 122 and the mounting groove 111, improving the vibration of the panel 120 relative to the middle frame 110, reducing the noise of the indoor unit 100 during operation, and improving the user experience.
