[0002] The water heater mask is provided with a screen (usually a glass plate, acrylic or other materials) and an operator. The screen covers the operator and can usually be connected by an adhesive layer or a snap connection. When the user presses the corresponding position on the screen, the operator obtains a corresponding electrical signal through the pressure change (for example, each button on the mainboard of the operator is provided with a spring pressure sensor. When the screen is pressed, the capacitance of some spring pressure sensors changes) and transmits it to the controller, thereby controlling the water output of the water heater body accordingly, such as adjusting the temperature, water volume, etc., so as to flexibly meet the needs of the user. The screen and the operator are basically arranged on the mask part of the shell. In order to make the screen larger (usually, users prefer a larger operating interface), the prior art generally adopts a design scheme in which the screen crosses the mask part.

[0003] However, this design scheme brings some problems. For example, due to the problem of combining the edges of the screen, operator and mask body, the manufacturing process of the water heater mask becomes complicated when dealing with the edge combination. For example, it involves welding and polishing processes, which increases the manufacturing cost of the water heater mask and thus increases the cost of the entire water heater.

[0072] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0073] like Figure 1-Figure 6 As shown, this embodiment provides a water heater mask, which includes a mask body 1 and an operator assembly 2. The mask body 1 includes a panel 11 and side panels 12 respectively connected to both sides of the panel 11 along the width direction. The plane where the side panels 12 are located forms an angle γ (such as Fig.12 As shown in FIG. 1 , γ = 90°, and the mask body 1 is provided with a mounting hole 13 that penetrates the panel 11 along the width direction. Of course, in other embodiments, γ may also take other values ​​other than zero, but considering the common form of the water heater mask, the structural adaptability of γ = 90° is the highest.

[0074] The mounting hole 13 is used to install the operator assembly 2, which includes a screen 22 and an operator 21 connected to each other. The size of the operator 21 is smaller than that of the screen 22. The size of the mounting hole 13 corresponds to that of the screen 22. The mounting hole 13 includes two first side walls arranged opposite to each other in the height direction.

[0075] The mask body 1 also includes two first supporting members, both of which are located inside the mounting hole 13, one end of the two first supporting members are respectively connected to the two first side walls, and the other end of the first supporting members can be fixedly connected to a side of the operator 21 away from the screen 22.

[0076] The mask body 1 is integrally formed. The structure after forming is shown in FIG. Figure 7-Figure 13 .

[0077] The first side wall includes a first part 1311 located on the panel, and a second part 1312 located on the side plate. The mounting hole 13 also includes two second side walls 132 arranged opposite to each other along the width direction. The second side wall 132 is located on the side of the side plate 12. An accommodating space 16 is formed between the second side wall 132 and the second part 1312. Both ends of the screen 22 are respectively located in the accommodating space 16.

[0078] In this way, by providing the water heater mask, the size of the mounting hole 13 opened in the mask body 1 is set to correspond to the size of the screen 22. In the formed structure, the mounting hole 13 includes two first side walls and two second side walls 132 arranged opposite to each other in the height direction, wherein the second side wall 132 is located on the side of the side panel 12, and the two ends of the screen 22 are respectively located in the accommodating space 16 between the second side wall 132 and the second part 1312 of the first side wall. After the operator assembly 2 is installed, the screen 22 crosses the water heater mask, expanding the width of the screen 22 as much as possible, rather than limiting the width of the screen 22 to be less than or equal to the width of the panel 11, which is convenient for users to use and avoids the problem of the edges of the screen 22, the operator 21 and the mask body 1 being combined. By setting one end of the two first supporting members in the mounting hole 13 to be connected to the two first side walls respectively, the other end of the first supporting member can be fixedly connected to the side of the operator 21 away from the screen 22, so that the operator 21 can be fixed from both ends. Since the operator 21 and the screen 22 are also fixed to each other, the entire operator assembly 2 can be firmly installed in the mounting hole 13. By setting the mask body 1 to be integrally formed, that is, the panel 11, the side plate 12 and the first supporting member are integrally formed, the manufacturing process of the water heater mask can be simplified, and the manufacturing cost of the water heater mask can be reduced.

[0079] In this embodiment, the operator assembly 2 is assembled by bonding the screen 22 to the operator 21 through an adhesive layer (not shown) with a thickness of about 0.8 mm. Of course, in other embodiments, the screen and the operator can also be connected by other connection methods such as buckles.

[0080] See also Figure 14-16 In this embodiment, the mask body 1 is stamped from a single sheet of metal. The panel width is L1, the accommodating space height is L2, the mounting hole 13 width is L3, and L3 = L1 + 2L2. Then, the mask body 1 can be formed by bending along the dotted line. The above manufacturing process is simple and avoids complex processes such as welding and injection molding.

[0081] In this embodiment, in the design of the stamping drawing, a distance of more than 3 mm is set between each structure to leave enough material thickness for the mold.

[0082] In this embodiment, the first supporting member includes a first vertical plate portion 141 and a first flat plate portion 142 connected in sequence, the first vertical plate portion 141 is perpendicular to the panel 11, the first flat plate portion 142 is parallel to the panel 11, the first vertical plate portion 141 is connected to the first side wall of the mounting hole 13, and the first flat plate portion 142 can be fixedly connected to the side of the operator 21 away from the screen 22. In this way, the two first flat plate portions 142 are fixedly connected to the side of the operator 21 away from the screen 22, and the two ends of the operator 21 can be limited by the first vertical plate portion 141, further firmly supporting the entire operator assembly 2 in the mounting hole 13.

[0083] In this embodiment, the width of the first vertical plate portion 141 gradually decreases in the direction away from the panel 11, and the angle α between the two side edges of the first vertical plate portion 141 and the first side wall of the panel 11 is 40°. In this way, it is possible to avoid the two side edges of the first vertical plate portion 141 and the second side wall 132 and the structure connected to the second side wall 132 from colliding during cutting and bending, which may cause difficulty in bending or unnecessary structural damage. Of course, in other embodiments, similar effects can be achieved by setting the angle between the two side edges of the first vertical plate portion 141 and the first side wall of the panel 11 to be less than 45°.

[0084] In this embodiment, the first flat plate portion 142 is threadedly connected to the operator 21, and a connecting hole 1421 is provided on the first flat plate portion 142. The connecting hole 1421 is used for passing a threaded connector (not shown in the figure) connected to the operator 21. In this way, the operator 21 and the first flat plate portion 142 can be connected and disassembled with a relatively simple structure.

[0085] In this embodiment, the first flat plate portion 142 is provided with an avoidance groove 1422, which is used to avoid the protrusion on the operator 21. In this way, structural conflicts between the first flat plate portion 142 and the protrusion on the operator 21, such as the positions where various components and wiring are concentrated, can be avoided during the installation of the operator assembly 2.

[0086] In this embodiment, the mask body 1 further includes two second supporting members, which are located inside the mounting hole 13, one end of the two second supporting members is respectively connected to the two second side walls 132, and the other end of the second supporting members can support the two ends of the screen 22. In this way, the entire operator assembly 2 can be further stably supported in the mounting hole 13, avoiding the shaking of the two ends of the screen 22 when pressed by the user.

[0087] In this embodiment, the second supporting member includes an inclined plate portion 151, a second vertical plate portion 152, and a second flat plate portion 153 which are connected in sequence. The angle between the inclined plate portion 151 and the panel 11 is an acute angle. The second vertical plate portion 152 is perpendicular to the panel 11, and the second flat plate portion 153 is parallel to the panel 11. The second flat plate portion 153 can support the two ends of the operator 21, and the inclined plate portion 151 can support the two ends of the screen 22.

[0088] The width of the inclined plate portion 151 gradually decreases in the direction away from the panel 11 , and the angle β between the two side edges of the inclined plate portion 151 and the second side wall 132 of the mounting hole 13 is 40°.

[0089] In this way, the second supporting member can support both ends of the screen 22 and the operator 21 at the same time, and further stably support the entire operator assembly 2 in the mounting hole 13. The shape of the inclined plate portion 151 can avoid the two side edges of the inclined plate portion 151 and the first side wall and the structure connected to the first side wall from colliding during cutting and bending, resulting in difficulty in bending or unnecessary structural damage. Of course, in other embodiments, the angle between the two side edges of the inclined plate portion 151 and the second side wall 132 of the panel 11 is set to be less than 45°, which can also achieve a similar effect.

[0090] In this embodiment, the height L2 of the accommodation space 16 is equal to the height of the screen 22. In this way, after the operator assembly 2 is installed, the screen 22 and the outer surface of the panel 11 are flush, and there is no large gap between the side of the operator assembly 2 and the side of the side panel 12. Of course, in other embodiments, the height of the accommodation space 16 is set to be less than the height of the screen 22, so as to form a raised screen; or the height of the accommodation space 16 is set to be greater than the height of the screen 22, so as to form a sunken screen.

[0091] In this embodiment, the water heater mask further includes a top plate 17, which is fixed to the top edge of the panel 11 and the top edge of the side plate 12. In this way, the relevant structures in the water heater mask can be further protected. Specifically, in this embodiment, the top plate 17 can be passed through by the smoke pipe and welded to the mask body 1; of course, in other embodiments, the top plate 17 can also be riveted to the mask body.

[0092] In this embodiment, the first side wall and the second side wall 132 are provided with flanges 18. In this way, the interior of the plate of the first side wall and the second side wall 132 can be prevented from being exposed to the respective side edges, and the strength of the first side wall and the second side wall 132 is increased. Of course, in other embodiments, the flanges may not be provided, or only the first side wall or the second side wall 132 may be provided with flanges.

[0093] In this embodiment, the first flat plate portion 142 and the second flat plate portion 153 are both chamfered to avoid scratching the assembler. Of course, in other embodiments, chamfering may not be performed to further simplify the processing technology.

[0094] This embodiment also provides a water heater, which includes the water heater cover as described above. In this way, the manufacturing cost of the water heater can be reduced.

[0095] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
