[0023] Reference Figures 1 to 10 As shown, the present invention provides a housing structure.

[0024] The housing structure includes a sink housing 100, a first connecting member 200, an upper housing 300, a second connecting member 400 and a first fastening member.

[0025] The sink shell 100 is a thin-walled shell made of metal material. The sink shell 100 is manufactured by stamping. A sink for collecting leaking liquid is arranged on the top of the sink shell 100. The front side and left and right sides of the sink shell 100 are respectively provided with sink side panels extending downward. The sink side panels on the left, front and right sides are connected as a whole. The sink side panels form a first curved surface 110 on the front side of the sink shell 100, and the first curved surface 110 gradually bends backward from the middle to the left and right sides.

[0026] A first flange 111 is disposed at the bottom edge of the first curved surface 110 . The first flange 111 is folded backwards and extends leftward and rightward to the left and right side panels of the sink.

[0027] The first connecting member 200 is connected to the top of the first flange 111 , and the first connecting member 200 extends leftward and rightward along the first flange 111 .

[0028] The upper shell 300 is a thin-walled shell made of metal material. The upper shell 300 is manufactured by stamping. A second curved surface 310 is provided on the front side of the upper shell 300. The second curved surface 310 gradually bends backward from top to bottom and gradually bends backward from the middle to the left and right sides. The top of the second curved surface 310 is flush with the bottom of the first curved surface 110, and the tops of the left and right sides of the upper shell 300 are flush with the tops of the left and right sides of the sink shell 100.

[0029] A second flange 311 is disposed at the top edge of the second curved surface 310 . The second flange 311 is folded backwards and extends leftward and rightward to the left and right sides of the upper shell 300 .

[0030] The second connecting member 400 is connected to the bottom of the second flange 311 , and the second connecting member 400 extends leftward and rightward along the second flange 311 .

[0031] The first fastener connects the first connecting member 200 and the second connecting member 400 together, thereby connecting the second curved surface 310 of the upper shell 300 and the first curved surface 110 of the sink shell 100 together.

[0032] Of course, two or more first fasteners may be provided, and the plurality of first fasteners are sequentially spaced and distributed along the extension direction of the first connecting member 200 or the second connecting member 400 .

[0033] When assembling the sink shell 100 and the upper shell 300, the first connecting member 200 is installed to the top of the first flange 111 of the first curved surface 110 of the sink shell 100, and then the second connecting member 400 is installed to the bottom of the second flange 311 of the second curved surface 310 of the upper shell 300. Thereafter, the first flange 111 of the sink shell 100 and the second flange 311 of the upper shell 300 are abutted against each other, and then the first fastener is used to connect the first connecting member 200 and the second connecting member 400. This can prevent the first fastener from being exposed on the front side of the sink shell 100 and the upper shell 300, and make the connection between the sink shell 100 and the upper shell 300 more convenient. After the first fastener is connected, it will not affect the first curved surface 110 of the sink shell 100 and the second curved surface 310 of the upper shell 300, thereby ensuring that the curved surface appearance effect of the shell structure is not affected.

[0034] In some embodiments, the shell structure is further provided with a second fastener and a third fastener, the second fastener connects the first flange 111 and the first connector 200 together, and the third fastener connects the second flange 311 and the second connector 400 together.

[0035] The first connecting member 200 is manufactured separately from the sink shell 100, and the second connecting member 400 is manufactured separately from the upper shell 300. During assembly, the first flange 111 and the first connecting member 200 are connected together by the second fastener, and the second flange 311 and the second connecting member 400 are connected together by the third fastener. During the manufacturing process of the sink shell 100 and the upper shell 300, the first connecting member 200 is prevented from affecting the stamping forming of the first curved surface 110, and the second connecting member 400 is prevented from affecting the stamping forming process of the second curved surface 310.

The first fastener passes through the first connecting member 220 and is screwed into the third reinforcement block 412, so that the third reinforcement block 412 and the first connecting member 200 are connected together.

[0045] The number of the third reinforcement blocks 412 can be designed according to the number of the first fasteners. When a plurality of third reinforcement blocks 412 are provided, the plurality of third reinforcement blocks 412 are provided in a one-to-one correspondence with the positions of the plurality of first fasteners.

[0054] The bottom edge of the lower shell 700 is provided with a third flange 710 folded backwards, and the fifth fastener sequentially connects the third flange 710 and the bottom of the bracket 500 from bottom to top.

[0055] Of course, there may be multiple fourth fasteners, which are spaced apart along the circumference of the upper shell 300 ; there may be multiple fifth fasteners, which are spaced apart along the extension direction of the third flange 710 .

[0056] A fourth fastener is set to connect the bottom of the upper shell 300 and the top of the bracket 500 from front to back, and then the decorative strip 600 is used to cover the front side of the fourth fastener. After that, the fifth fastener connects the third flange 710 at the bottom of the lower shell 700 to the bottom of the bracket 500, so that the sink shell 100, the upper shell 300, the bracket 500, the decorative strip 600 and the lower shell 700 form a whole, so as to facilitate the installation of related equipment such as a water purifier in the space surrounded by the sink shell 100, the upper shell 300, the bracket 500, the decorative strip 600 and the lower shell 700. The decorative strip 600 covers the fourth fastener, so that the joint position of the shell structure is more compact, ensuring that the curved appearance effect of the shell structure is not affected.

[0057] In some embodiments, reference Fig. 9 and Fig.10 As shown, the decorative strip 600 covers the gap between the bottom of the upper case 300 and the top of the lower case 700 .

[0058] The decorative strip 600 covers the joint position of the upper shell 300 and the lower shell 700, making the joint position of the shell structure more compact, ensuring that the curved surface appearance of the shell structure is not affected.
