Description

Technical Field

[0001] This utility model relates to the field of appearance decoration structure technology, and in particular to a panel structure, an air conditioner having the panel structure, and a household appliance having the panel structure. Background Technology

[0002] With the improvement of living standards and the continuous development of home appliance technology, consumers have higher and higher requirements for the appearance of home appliances. As a result, decorative strips are being used more and more widely on home appliances, such as adding decorative strips to the panels of home appliances such as air conditioners and dehumidifiers to enhance their aesthetics.

[0003] The existing assembly method between the decorative strip and the panel uses a pure snap-fit ​​structure, which is not stable and reliable enough. During product transportation or operation, the decorative strip is prone to loosening and producing abnormal noises. It also causes an appearance gap between the decorative strip and the panel, affecting the product's appearance. In addition, with the long-term use, the snap-fit ​​structure will harden and break, and the decorative strip is prone to falling off, which in turn affects the product's appearance. Summary of the Invention

[0004] To achieve the primary objective of this utility model, it provides a panel structure that is securely and firmly assembled, avoiding abnormal noises and gaps in the appearance, thereby improving the aesthetic appeal of the product.

[0005] To achieve the second objective of this utility model, this utility model provides an air conditioner having the above-described panel structure.

[0006] To achieve the third objective of this utility model, this utility model provides a household appliance having the above-described panel structure.

[0007] To achieve the primary objective of this utility model, a panel structure is provided, including an outer panel and a decorative ring. The outer panel has a decorative hole. The decorative ring includes a first outer decorative ring segment, a second outer decorative ring segment, and an inner mounting ring segment connected sequentially. A support ring protrudes from the periphery of the decorative hole. The support ring is inserted into a U-shaped groove formed between the first outer decorative ring segment, the second outer decorative ring segment, and the inner mounting ring segment. The first outer decorative ring segment is located on the outer surface of the support ring, and the inner mounting ring segment is located on the inner surface of the support ring. The first protruding buckle is provided, and the inner side of the support ring is provided with a second protruding buckle. The inner side of the first outer trim ring segment is recessed and has a first groove. The inner side of the inner mounting ring segment is recessed and has a second groove. The first protruding buckle hooks into the first groove, and the second protruding buckle hooks into the second groove. The outer side of the support ring is provided with a ring rib protruding from the outer end away from the second outer trim ring segment. The ring rib abuts against the inner side of the first outer trim ring segment. The inner side of the support ring is provided with a top rib protruding from the inner side. The top rib abuts against the inner side of the inner mounting ring segment.

[0008] As can be seen from the above scheme, the support ring of the outer panel of the present invention is inserted into the U-shaped groove formed between the first outer decorative ring segment, the second outer decorative ring segment, and the inner mounting ring segment of the decorative ring.

The decorative ring 12 includes a first outer decorative ring segment 121, a second outer decorative ring segment 122 and an inner mounting ring segment 123 connected in sequence. A support ring 112 protrudes from the peripheral wall of the decorative hole 111. The support ring 112 is inserted into a U-shaped groove 124 formed between the first outer decorative ring segment 121, the second outer decorative ring segment 122 and the inner mounting ring segment 123. The first outer decorative ring segment 121 is located on the outer surface of the support ring 112 and the inner mounting ring segment 123 is located on the inner surface of the support ring 112. Furthermore, in this embodiment, the outer side of the support ring 112 is provided with a first protruding buckle 1122, and the inner side of the support ring 112 is provided with a second protruding buckle 1123. The inner side of the first outer decorative ring segment 121 is provided with a first recessed slot 1211, and the inner side of the inner mounting ring segment 123 is provided with a second recessed slot 1232. The first protruding buckle 1122 hooks into the first slot 1211, and the second protruding buckle 1123 hooks into the second slot 1232. The outer side of the support ring 112 is provided with a ring rib 1124 protruding away from the outer end of the second outer decorative ring segment 122. The ring rib 1124 abuts against the inner side of the first outer decorative ring segment 121. The inner side of the support ring 112 is provided with a top rib 1127 protruding, and the top rib 1127 abuts against the inner side of the inner mounting ring segment 123.

[0039] In this embodiment, the support ring 112 of the outer panel 11 of the panel structure 10 is inserted into the U-shaped groove 124 formed between the first outer decorative ring segment 121, the second outer decorative ring segment 122, and the inner mounting ring segment 123 of the decorative ring 12. The first outer decorative ring segment 121 of the decorative ring 12 is located on the outer surface of the support ring 112, and the inner mounting ring segment 123 of the decorative ring 12 is located on the inner surface of the support ring 112. This ensures that the first outer decorative ring segment 121, the second outer decorative ring segment 122, and the inner mounting ring segment 123 of the decorative ring 12 cover the support ring 112 of the outer panel 11. Furthermore, in this embodiment, the support ring 11... The outer side of the 2 has a first protruding buckle 1122, and the inner side of the support ring 112 has a second protruding buckle 1123. The inner side of the first outer decorative ring segment 121 has a first recessed slot 1211, and the inner side of the inner mounting ring segment 123 has a second recessed slot 1232. The first protruding buckle 1122 hooks into the first slot 1211, and the second protruding buckle 1123 hooks into the second slot 1232. Thus, the double protruding buckles are used for fixed assembly, which can effectively prevent the decorative ring 12 from becoming loose relative to the outer panel 11, and make the assembly of the decorative ring 12 and the outer panel 11 stable and reliable. Furthermore, in this embodiment, a ring rib 1124 protrudes from the outer end of the support ring 112 of the outer panel 11 away from the second outer decorative ring segment 122. This ring rib 1124 abuts against the inner side of the first outer decorative ring segment 121 of the decorative ring 12, thereby avoiding an appearance gap between the first outer decorative ring segment 121 of the decorative ring 12 and the appearance surface of the outer panel 11, so that the decorative ring 12 and the outer panel 11 form a seamless appearance. Additionally, a top rib 1127 protrudes from the inner side of the support ring 112 of the outer panel 11. The top rib 1127 abuts against the inner side of the inner mounting ring 123 of the decorative ring 12. The abutting force of the annular rib 1124 against the first outer decorative ring 121 of the decorative ring 12 is opposite to the abutting force of the top rib 1127 against the inner mounting ring 123 of the decorative ring 12. This ensures that the decorative ring 12 is stably supported on the support ring 112 of the outer panel 11, further improving the assembly stability and reliability of the decorative ring 12 and the outer panel 11, avoiding abnormal noise and appearance gaps, thereby improving the aesthetic appearance of the product.

[0040] Combination Figure 10In this embodiment, the first protruding buckle 1122 has a first abutting rib (not shown) protruding from the side of the support ring 112 radially away from the second outer decorative ring segment 122. The first abutting rib abuts against the side of the groove of the first slot 1211 radially away from the second outer decorative ring segment 122, so that the first protruding buckle 1122 is securely hooked into the first slot 1211, thereby improving the assembly stability and reliability of the decorative ring 12 and the outer panel 11. Furthermore, in this embodiment, the second protruding buckle 1123 has a second abutting rib 11231 protruding from the side of the support ring 112 radially away from the second outer decorative ring segment 122. The second abutting rib 11231 abuts against the side of the groove of the second slot 1232 radially away from the second outer decorative ring segment 122, so that the second protruding buckle 1123 is securely hooked into the second slot 1232, thereby improving the assembly stability and reliability of the decorative ring 12 and the outer panel 11. Specifically, in this embodiment, the first protruding buckle 1122, the second protruding buckle 1123, and the inner mounting ring segment 123 are equipped with guide slopes in the assembly direction, which can improve the smoothness and convenience of assembly and prevent cracking of various structures during assembly, thus affecting the stability and reliability of the assembly.

[0041] Combination Figure 11 , Figure 18 and Figure 19 In this embodiment, the outer side of the support ring 112 of the outer panel 11 has a protruding dot 1125 near the inner end of the second outer trim ring segment 122.

The abutment surface 11271 of the top rib 1127 abuts against the inner surface of the inclined plate segment 1233, thereby dispersing the abutment force in the axial and radial directions of the support ring 112, thus ensuring that the decorative ring 12 is stably supported on the support ring 112 of the outer panel 11. Specifically, the inclined plate segment 1233 in this embodiment is arc-shaped, and the area of ​​the inclined plate segment 1233 gradually increases and then decreases in the arc extension direction. During assembly, the inclined plate segment 1233 with the increased area can be easily grasped, thereby facilitating installation.

[0043] Combination Figure 2 , Figure 12 and Figure 13 In this embodiment, the inner side of the inner mounting ring segment 123 of the decorative ring 12 is provided with a protrusion 1237. The protrusion 1237 abuts against the inner side of the support ring 112. The protrusion 1237 can prevent the decorative ring 12 from making abnormal noise due to thermal expansion and contraction, and improve the assembly stability and reliability while avoiding the generation of abnormal noise.

[0044] Combination Figure 6 and Figure 7 In this embodiment, the inner side of the support ring 112 is provided with a first limiting platform 1128, and the inner mounting ring segment 123 is provided with a first limiting groove 1234. The first limiting platform 1128 is inserted into the first limiting groove 1234. In addition, the inner side of the support ring 112 is provided with a second limiting platform 1129, and the inner mounting ring segment 123 is provided with a second limiting groove 1236. The second limiting platform 1129 is inserted into the second limiting groove 1236, thereby further improving the assembly stability and reliability as well as the assembly accuracy.

[0045] To further improve the stability and precision of the assembly, in this embodiment, the first limiting platform 1128 has third protruding buckles 11281 protruding from opposite sides of the support ring 112 in the circumferential direction, and the first limiting groove 1234 has third recessed slots 1235 on opposite sides of the support ring 112 in the circumferential direction, with one third protruding buckle 11281 hooking into one third slot 1235. Furthermore, this embodiment has two second limiting platforms 1129 and two second limiting grooves 1236, with the two second limiting platforms 1129 symmetrically arranged about the central axis of the support ring 112. One second limiting platform 1129 is inserted into one second limiting groove 1236, thereby ensuring that the decorative ring 12 is centrally mounted on the support ring 112 of the outer panel 11, improving assembly precision, preventing misalignment that could create a double eyelid effect, and ultimately enhancing the aesthetic appeal.

[0046] Specifically, in this embodiment, the support ring 112 of the exterior panel 11 is in the shape of a ring racetrack. The two second limiting platforms 1129 are symmetrically arranged about the length center axis 113 of the support ring 112, and the two second limiting platforms 1129 and the first limiting platform 1128 are arranged opposite to each other about the width center axis 114 of the support ring 112, so that the decorative ring 12 is accurately and securely assembled on the support ring 112 of the exterior panel 11.

[0047] To further improve assembly accuracy, in this embodiment, a positioning platform 1121 is provided on the inner side of the support ring 112, and a positioning groove 1231 is provided on the inner side of the mounting ring segment 123, and the positioning platform 1121 is inserted into the positioning groove 1231.

[0048] Furthermore, in this embodiment, the decorative ring 12 can be made of an elastic or flexible material, which makes it easier for the first outer decorative ring segment 121, the second outer decorative ring segment 122 and the inner mounting ring segment 123 of the decorative ring 12 to tightly cover the support ring 112 of the outer panel 11 and adapt to the shape of the support ring 112 of the outer panel 11, thereby improving the speed of assembly.

[0049] The panel structure 10 described above can be applied to air conditioners to improve their appearance, and can also be applied to other household appliances, such as dehumidifiers, air purifiers, humidifiers, fans, washing machines, etc.

[0050] The above embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model.
