[0002] A gas water heater, also known as a gas water boiler, is a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] After sufficient market research, it is found that gas water heaters with a large-screen appearance display structure are more popular with consumers. The control structure of the large screen includes a support plate that supports the display screen, a keypad backplane that fixes the keypad, and the face shell of the gas water heater must be connected to the display assembly. In the prior art, screws and studs are often used to connect them in sequence. This connection method is relatively complicated and the operation is cumbersome. In addition, the connection between the components is not tight enough and the fixing structure is not very reliable. Utility Model Content

[0004] In order to solve the above technical problems, the present application further improves the matching structure of the existing display assembly and the gas water heater shell, in order to simplify the assembly process and make the assembly structure more reliable. One of the purposes of the present utility model is to provide a matching structure of a display assembly on the shell, the second purpose is to provide a corresponding display assembly, and the third purpose is to provide a corresponding gas water heater.

[0005] The specific technical solutions are described below:

[0006] The matching structure of the display component on the face shell includes:

[0007] A support plate, wherein a plurality of boss mounting members are arranged at intervals in a circumferential region on one side of the support plate, wherein the boss mounting member is provided with a convex portion, and a fastening mounting hole is opened on the convex portion;

[0008] A keypad back plate, wherein a plurality of concave mounting members are arranged at intervals in a circumferential region on one side of the keypad back plate, wherein the concave mounting members are provided with concave portions, wherein the concave portions are provided with positioning mounting holes, wherein the number of the concave mounting members matches the number of the convex mounting members, and the end of the convex portion is accommodated in the concave portion to form a combined structure, wherein the support plate and the keypad back plate are fixedly connected through a plurality of groups of the combined structures;

[0009] A fastener, one end of which locks the concave portion at the end of the convex portion through the positioning installation hole, and the other end of which is tightly connected in the fastening installation hole;

[0044] Reference Figures 2~5In this matching structure, three boss mounting members 1 are evenly and spacedly arranged in the circumferential area inside the support plate e, and the protruding part of the boss mounting member 1 is a convex part 1-1, and a fastening mounting hole 1-2 is opened on the convex part 1-1;

[0045] At the corresponding position, three recessed platform mounting parts 2 are evenly and spaced apart in the circumferential area on the inner side of the keypad back plate b, a recessed part 2-1 is provided at the end of the recessed platform mounting part 2, a groove is provided on the recessed part 2-1, a positioning mounting hole 2-2 is provided in the groove, and the end of the protrusion 1-1 is accommodated in the groove on the recessed part 2-1 to form a combined structure, and the combined structure is fixedly connected with screws as the fixing parts 3, and the support plate e and the keypad back plate b are fixedly connected through three groups of combined structures.

[0046] Specifically, one end of the screw locks the recessed portion 2-1 at the end of the protruding portion 1-1 through the positioning mounting hole 2-2. The positioning mounting hole 2-2 cooperates with the head of the screw to form a snap-fit ​​positioning structure to position the key board back panel b. The other end of the screw is fastened to the fastening mounting hole 1-2. The inner wall of the fastening mounting hole 1-2 cooperates with the stud of the screw to form a threaded fastening structure.

[0047] In the matching structure of this embodiment, a mounting hole for the display assembly is provided on the face shell d, and three clip holes 4 are provided at the edge of the mounting hole. The clip holes 4 are sleeved on the protrusion 1-1 so that the face shell d is connected between the support plate e and the keypad back plate b.
