Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] This embodiment proposes a front shell assembly and a gas water heater. The gas water heater includes a bottom shell assembly, a fan, a heat exchanger, a burner, a jet pipe, a proportional valve, and the aforementioned front shell assembly. The bottom shell assembly and the front shell assembly together form a receiving cavity, and the heat exchanger, fan, burner, proportional valve, and jet pipe are all located within the receiving cavity.

[0036] like Figures 1-8As shown, the front cover assembly includes a front cover assembly 10, a display assembly 20, and fasteners 30. The front cover assembly 10 includes a main housing 11 and a glass panel 12. The display assembly 20 includes a display back cover 21 and a display body 22 mounted on the display back cover 21. The display body 22 is fixed to the display back cover 21. The display back cover 21 is fixedly mounted to the main housing 11 by fasteners 30. The glass panel 12 is fixed to the outside of the main housing 11 (the side of the main housing 11 facing away from the display assembly 20) and covers the display body 22. To reduce the number of fasteners 30, a positioning flap 112 is provided extending inward on the main housing 11 (the side of the main housing 11 facing the display assembly 20). The positioning flap 112 has a positioning flange hole 1121. The display back cover 21 has a pre-installed boss 213, which is inserted into the positioning flange hole 1121. Meanwhile, the main housing 11 and the display back cover 21 are respectively provided with a first mounting hole 1111 and a second mounting hole 2111. The first mounting hole 1111 and the second mounting hole 2111 are aligned and set. The fastener 30 passes through the first mounting hole 1111 and the second mounting hole 2111 to fix the main housing 11 and the display back cover 21. The fastener 30 includes a screw, which can be threaded to the main housing 11, or the fastener 30 is a bolt, which is fixed by a nut.

[0037] The aforementioned faceplate assembly can initially limit the position of the display component 20 by using the pre-installed boss 213 inserted into the positioning flap 112, and then further fix the display component 20 and the faceplate assembly 10 by using fasteners 30. Compared with simply fixing the display component 20 and the faceplate assembly 10 by using fasteners 30, the number of fasteners 30 can be reduced, thereby reducing the assembly time of fasteners 30, improving the assembly efficiency of the faceplate assembly and the gas water heater including the faceplate assembly, and also reducing the labor manufacturing cost of the faceplate assembly and the gas water heater.

[0038] In this embodiment, two pre-installed bosses 213, two positioning flaps 112, two first mounting holes 1111, and two second mounting holes 2111 are provided. Compared with the previous use of four screws, the use of at least two fasteners 30 can be reduced. It should be emphasized that in order to improve the stability of the assembly between the display assembly 20 and the front shell assembly 10, the pre-installed bosses 213 and the second mounting holes 2111 are located on opposite sides of the display back cover 21. Specifically, the display back cover 21 includes a cover body 211 and a first wall plate 212 and a second wall plate disposed on opposite sides of the cover body 211. The two pre-installed bosses 213 are both disposed on the second wall plate and are spaced apart along the width direction of the main shell 11 (left and right direction in the figure). The two second mounting holes 2111 are spaced apart along the width direction of the main shell 11 on the side of the cover body 211 near the first wall plate 212.

[0039] Understandably, the pre-mounted boss 213 abuts against the opposite side walls of the positioning flange hole 1121 on both sides along the width direction of the main housing 11 to reduce the possibility of the pre-mounted boss 213 wobbling within the positioning flange hole 1121. Furthermore, when the pre-mounted boss 213 is aligned with the positioning flange hole 1121, the first mounting hole 1111 and the second mounting hole 2111 through which the same fastener 30 passes are located on the same straight line. Pushing the pre-mounted boss 213 into the positioning flange hole 1121 allows the first mounting hole 1111 and the second mounting hole 2111 to align, reducing the alignment time of the first mounting hole 1111 and the second mounting hole 2111. Specifically, the side of the pre-mounted boss 213 away from the first wall panel 212 is provided with an inclined guide surface to reduce the difficulty of inserting the pre-mounted boss 213 into the positioning flange hole 1121.

[0040] In this embodiment, the display back cover 21 and the main housing 11 are respectively provided with two third mounting holes 2112 and a fourth mounting hole 1115. The third mounting hole 2112 is located on the side of the cover body 211 near the second wall panel, and the fourth mounting hole 1115 is aligned with the third mounting hole 2112. Therefore, when the display back cover 21 and / or the main housing 11 are deformed during the processing, making it difficult for the pre-installed boss 213 to be inserted into the positioning flange hole 1121, the fasteners 30 passing through the third mounting hole 2112 and the fourth mounting hole 1115 can still be used to fix the display back cover 21 and the main housing 11.

[0041] refer to Figure 3 and Figure 4 As shown, in order to further reduce the difficulty of aligning the first mounting hole 1111 and the second mounting hole 2111 during assembly and to further improve assembly efficiency, a limiting rib 214 is provided on the pre-installed boss 213. When the limiting rib 214 abuts against the positioning flap 112, the first mounting hole 1111 and the second mounting hole 2111 are coaxial.

[0042] Specifically, two limiting ribs 214 are provided at intervals along the width direction of the main housing 11 on the pre-installed boss 213 to reduce the possibility of tilting when the display back cover 21 is assembled onto the main housing 11. It can be understood that in addition to its limiting function, the limiting ribs 214 can also improve the structural strength of the pre-installed boss 213.

[0043] In this embodiment, the main housing 11 is a sheet metal part, including a front side plate 111. The front side plate 111 is punched to form a positioning flap 112, which is set at an angle to the front side plate 111. A first mounting hole 1111 is formed on the front side plate 111, reducing the processing difficulty of the main housing 11. Specifically, the angle between the positioning flap 112 and the front side plate 111 is 90°. When the pre-mounted boss 213 is inserted into the positioning flap hole 1121, the display back cover 21 moves in a direction parallel to the main housing 11. It can be understood that the "parallel" mentioned in the above description includes approximately parallel. The display back cover 21 is a plastic back cover. The pre-mounted boss 213 is integrally formed with the cover body 211, the first wall plate 212, and the second wall plate through injection molding, which improves the structural strength of the display back cover 21 and reduces the cost.

[0044] Specifically, in order to prevent shrinkage during the molding process of the pre-mounted boss 213, which would affect the positioning accuracy of the limiting rib 214, a through hole 2131 is provided on the pre-mounted boss 213. The through hole 2131 can also reduce the material used in the processing of the display back cover 21, thereby reducing costs.

[0045] In addition, to prevent the main housing 11 from twisting during processing, a reinforcing rib 1114 is provided on the front side plate 111, and the reinforcing rib 1114 extends along the length direction of the main housing 11. Specifically, two reinforcing ribs 1114 are provided at intervals along the width direction of the main housing 11.

[0046] In other embodiments, the positioning flap 112 and the front side plate 111 can also be fixed by welding or bonding, which will not be described in detail here.

[0047] refer to Figure 2 , Figure 7 and Figure 8 As shown, to further improve the connection stability between the monitor back cover 21 and the main housing 11 and prevent the monitor assembly 20 from shaking, a positioning hole 1112 is also provided on the front side panel 111. A plug-in part 215 is provided on the side of the monitor back cover 21 facing the positioning hole 1112. The plug-in part 215 is inserted into the positioning hole 1112 to realize the plug-in positioning of the monitor back cover 21 and the main housing 11. Specifically, the plug-in part 215 is set as a ring, and the monitor body 22 is fixed to the inner side of the ring of the plug-in part 215. The second mounting hole 2111 is provided between the plug-in part 215 and the first wall panel 212, and the third mounting hole 2112 is provided between the plug-in part 215 and the second wall panel.

[0048] When the display assembly 20 is assembled into the front shell assembly 10, the pre-installed boss 213 is first inserted into the positioning flange hole 1121 until the limiting rib 214 abuts against the positioning flange 112. Then, a force is applied to the display assembly 20 to press against the front shell assembly 10, so that the plug part 215 is inserted into the positioning hole 1112 until the display assembly 20 is close to the main housing 11. Then, the fastener 30 is passed through the first mounting hole 1111 and the second mounting hole 2111 and fixed.

[0049] Continue to refer to Figure 8 As shown, the front panel 111 has an annular positioning boss 1113 protruding towards the display assembly 20 at the outer edge of the positioning hole 1112. The first mounting hole 1111 is opened on the positioning boss 1113 to avoid damaging the glass panel 12 when assembling the fastener 30. Moreover, the first wall panel 212 and the second wall panel both abut against the positioning boss 1113 to avoid excessive compression of the display assembly 20 when assembling the display assembly 20 onto the front panel assembly 10, which would affect the lifespan of the display assembly 20.

[0050] refer to Figure 2 As shown, the front side panel 111 has a first folded edge 113 and a second folded edge 114 formed by bending the upper and lower edges respectively. The first folded edge 113 includes a first extension 1131 extending into the front side panel 111 and a second extension 1132 connected to the end of the first extension 1131 away from the front side panel 111 and extending away from the front side panel 111 along the length direction of the main housing 11. The second extension 1132 can be inserted into a first insertion hole provided on the bottom housing assembly. The second folded edge 114 extends inward and has a fifth mounting hole 1141 for engaging with a sixth mounting hole provided on the bottom housing assembly. The front housing assembly is fixedly connected to the bottom housing assembly by fasteners 30 passing through the fifth mounting hole 1141 and the sixth mounting hole.

[0051] In this embodiment, three fifth mounting holes 1141 are provided at intervals along the width direction of the main housing 11 on the second folded edge 114. In other embodiments, the number of fifth mounting holes 1141 and sixth mounting holes can be appropriately increased or decreased according to the width dimension of the main housing 11.

[0052] The first fold 113 setting can also reduce the number of fasteners 30 used when assembling the front shell assembly to the bottom shell assembly, further improving the assembly efficiency of the gas water heater and reducing labor manufacturing costs.

[0053] The main housing 11 also includes hooks 115 disposed on the left and right edges of the front side panel 111, the hooks 115 extending inward into the front side panel 111 and arranged in an L-shape. Correspondingly, the bottom housing assembly is provided with a locking hole for inserting the hooks 115. The arrangement of the hooks 115 and the locking holes further increases the connection stability between the front housing assembly and the bottom housing assembly. It should be emphasized that the direction in which the hooks 115 are inserted into the locking holes is the same as the direction in which the first folded edge 113 is inserted into the first insertion hole.

[0054] It is understandable that after the hook 115 is engaged with the locking hole, it can limit the positioning of the face shell assembly and the bottom shell assembly along the width direction of the main shell 11. In this embodiment, in order to reduce the assembly difficulty of the face shell assembly and the bottom shell assembly, one hook 115 is provided on each of the left and right sides of the front side plate 111 and is centrally located. On this basis, the main shell 11 also includes inserts 116 provided on the left and right edges of the front side plate 111. The two inserts 116 are respectively provided on the upper and lower sides of the hook 115 along the length direction of the main shell 11. The inserts 116 extend into the front side plate 111. The bottom shell assembly is provided with a second insertion hole corresponding to the inserts 116. The inserts 116 can be inserted into the second insertion hole to limit the left and right sides of the upper and lower parts of the face shell assembly.

[0055] When the front shell assembly is assembled into the bottom shell assembly, the first folded edge 113 of the front shell assembly is tilted close to the first insertion hole on the bottom shell assembly. During the process of inserting the first folded edge 113 and the hook 115 into the first insertion hole and the hook hole respectively, the second folded edge 114 is brought close to the bottom shell assembly and the fifth mounting hole 1141 on the second folded edge 114 is aligned with the sixth mounting hole on the bottom shell assembly. The fastener 30 is installed in the fifth mounting hole 1141 and the sixth mounting hole to complete the assembly of the front shell assembly and the bottom shell assembly.

[0056] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0057] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
