Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a mask assembly of a water heater and a water heater comprising the mask assembly. Background Art

[0002] The mask determines the appearance of the water heater to a great extent, and will affect consumers' purchasing intention to a certain extent. Among them, the shape of the mask itself, the connection strength requirements, and the connection method between the mask and the box are the main factors affecting the overall appearance of the mask.

[0003] The conventional mask forming process of water heaters mainly relies on sheet metal bending, and then fixes the mask and the box body by spot welding or screw connection, and the side is strengthened by designing a snap-on structure. However, the existing technical means of fixing the mask and the box body by spot welding or screw connection, and the side snap-on method, coupled with the thin characteristics of the mask itself, are prone to deformation, dents (spot welding places produce dents due to heat), scratches on the paint surface (scratches on the paint surface at the screw connection), and other unsightly phenomena. On the other hand, before being welded or screwed, the mask formed by sheet metal bending (usually U-shaped) has a tendency to expand toward the plane relative to the front panel due to the lack of physical structural support, that is, the bent mask has an internal stress that flattens toward the plane. In this case, since the mask is a sheet metal part, it is generally thin and its own strength is not high. When it is impacted by external force, the mask is prone to collapse and deformation, affecting the appearance; if welding is used, the spot welding places may produce phenomena such as desoldering, and if screw connection is used, too many screw connections will greatly affect the aesthetics. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the mask of the water heater is prone to be unsightly when being bent and connected, and to provide a water heater mask assembly and a water heater comprising the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A mask assembly for a water heater, the mask assembly comprising a mask, the mask comprising a front panel and at least one folded side panel directly or indirectly connected to the front panel, and a first folded edge folded from an edge of the front panel toward an inner side of the mask and a second folded edge folded from an edge of the side panel toward an inner side of the mask, wherein the first folded edge and the second folded edge are located on the same side of the front panel and the side panel.

[0007] The mask assembly further comprises a connector, wherein the connector is attached to the first folded edge and the second folded edge on the inner side and / or the outer side of the mask; the first folded edge and the second folded edge are respectively provided with at least one through hole, and the surface of the connector is provided with at least two protrusions, and the two protrusions are respectively matched with the through hole of the first folded edge and the through hole of the second folded edge,

[0008] The connecting piece is made of a magnetic material, and is connected to the mask by magnetic adsorption; or, the connecting piece is made of a non-magnetic material, and is connected to the mask by the cooperation of the protrusion and the through hole.

[0009] In this solution, the mask assembly of the water heater can overcome the internal stress of the mask by matching the protrusion on the connecting piece with the through hole of the mask folded edge, so as to limit the side panel from flattening toward the front panel, so that the mask maintains the bending angle. The connecting piece is fixed to the mask by magnetic adsorption or the matching of the protrusion and the through hole to prevent the connecting piece from falling off the mask, so that the mask can maintain the structural shape of the bending formation, improve the overall strength of the mask, and curb the flattening trend of the mask. In addition, since there is no need for welding or additional parts such as screws between panels in different directions and between folded edges, defects such as deformation and collapse are avoided, and the aesthetics are improved.

[0010] Preferably, when the connecting member is made of magnetic material, the protrusion and the through hole are loosely matched.

[0011] In this solution, when the connector is made of magnetic material, the connector is connected to the mask by magnetic adsorption, that is, the connector does not need to be connected to the mask by interference fit between the protrusion and the through hole or other fitting methods, and can maintain the bent shape; on this basis, the protrusion and the through hole adopt a clearance fit to facilitate the assembly operation between the connector and the mask.

[0012] Preferably, the mask assembly further comprises an elastic member, wherein the elastic member is connected to the two connecting members on both sides of the mask.

[0013] In this solution, the connectors on both sides of the mask are connected by elastic parts to form a tensioning force perpendicular to the magnetic adsorption force (the direction of the magnetic adsorption force is the installation direction of the connector and the mask), so that the protrusions of the connectors on both sides are tightly fitted with the through holes along the tensioning force direction, and the friction force generated ensures that the connectors will not fall off. In this way, when the magnetism of the connectors declines and the magnetic connection force is insufficient, the connectors on both sides of the mask can be effectively kept firmly connected to the mask, which improves the aesthetics and the connection reliability.

[0014] Preferably, when the connecting member is made of non-magnetic material, the protrusion is interference fit with the through hole, and / or the protrusion passes through the through hole and is connected to a fastener on the opposite side of the connecting member.

[0015] In this solution, when the connecting piece is made of non-magnetic material, the soil and the through hole can be connected to the mask through interference fit and / or through connecting fasteners, so that the connecting piece will not fall off.

[0016] Preferably, the connecting member is attached to the inner side of the mask, and the edge of the connecting member is attached to the fold line between the first folded edge and the front panel, and the fold line between the second folded edge and the side panel.

[0017] Preferably, the first folded edge and the second folded edge are arranged at intervals.

[0018] In this solution, the first folded edge and the second folded edge are spaced apart, and during assembly, the bending angles of different panels of the mask are easily adjusted. After bending, the different panels tend to flatten, and the tension generated can improve the reliability of the connection between the connector and the mask.

[0019] Preferably, the edge of the connecting member extending toward the inner cavity of the mask does not exceed the edges of the first folded edge and the second folded edge extending toward the inner cavity of the mask.

[0020] In this solution, through the above-mentioned arrangement, the edge of the fold is kept beautiful, which is beneficial to the beauty of the mask.

[0021] Preferably, the height of the protrusion is not greater than the depth of the through hole, or the height of the protrusion is greater than the depth of the through hole, and the portion of the protrusion protruding from the through hole is used to connect with other components of the water heater.

[0022] In this solution, when the height of the protrusion is not greater than the depth of the through hole, the surface of the folded edge is kept flat and beautiful. When the height of the protrusion is greater than the depth of the through hole, the protruding portion can be used to connect other parts of the water heater, thereby improving the connection strength between the mask and other parts.

[0023] Preferably, the mask further comprises a transition panel and a third folded edge bent from an edge of the transition panel toward the inner side of the mask, and the front panel is connected to the side panel via the transition panel;

[0024] The third folded edge is provided with at least one through hole, and the surface of the connecting piece is provided with at least three protrusions, which also cooperate with the through hole of the third folded edge. The three protrusions connected to the first folded edge, the second folded edge and the third folded edge are not on the same straight line.

[0025] In this solution, three protrusions that are not on the same straight line are respectively matched and connected with the through holes of the three folded edges, so that the connection strength is improved, the possibility of deformation is reduced, and the reliability of maintaining the bending shape is improved.

[0026] A water heater comprises the mask assembly as described above.

[0027] In the present solution, the water heater realizes the connection between the connector and the mask through the above-mentioned mask assembly by magnetic adsorption or the cooperation of the protrusion and the through hole, so that the mask can maintain the bent structural shape, does not require welding or additional parts such as screws, avoids defects such as deformation and collapse, and improves the aesthetics.

[0028] The positive progressive effect of the utility model is that the mask assembly of the water heater and the water heater including the same realize the connection between the connecting part and the mask through magnetic adsorption or the cooperation of the protrusion and the through hole, so that the mask can maintain the structural shape of the bending formation, does not require additional parts such as welding or screws, avoids defects such as deformation and collapse, and improves the aesthetics.

[0050] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0051] Example 1

[0052] The present embodiment provides a mask assembly 1 for a water heater, which is installed in front of the water heater main unit to protect the components inside the main unit. A display screen is also installed on the mask assembly 1 to facilitate users to set up and operate the water heater and to know the usage status of the water heater.

[0053] like Figure 1-6 As shown, the mask assembly 1 includes a mask, which includes a front panel 2 and at least one bent side panel 3 directly or indirectly connected to the front panel 2, as well as a first folded edge 5 bent from the edge of the front panel 2 toward the inner side of the mask and a second folded edge 6 bent from the edge of the side panel 3 toward the inner side of the mask, the first folded edge 5 and the second folded edge 6 are located on the same side of the front panel 2 and the side panel 3.

[0054] The mask assembly 1 also includes a connector 9, which is attached to the first folded edge 5 and the second folded edge 6 on the inner side and / or outer side of the mask; the first folded edge 5 and the second folded edge 6 are respectively provided with at least one through hole 8, and the surface of the connector 9 is provided with at least two protrusions 11, which respectively cooperate with the through hole 8 of the first folded edge 5 and the through hole 8 of the second folded edge 6. The material of the connector 9 is a magnetic material, and the connector 9 is connected to the mask by magnetic adsorption.

[0055] Specifically, in this embodiment, the mask is a sheet metal structure with a multi-faceted structure, which is bent into a U-shaped cover shell through a stamping process. The mask includes a front panel 2, two side panels 3 and two transition panels 4 connecting the front panel 2 and the side panels 3. The top and bottom edges of each panel are bent into strip-shaped folds toward the inside of the mask, that is, the front panel 2 is bent into a first fold 5, the side panel 3 is bent into a second fold 6, and the transition panel 4 is bent into a third fold 7. It should be noted here that the "inside" of the mask refers to the side of the mask that wraps around the water heater main unit, which is the inner cavity of the U-shaped mask, and the "outside" of the mask refers to the side of the mask that faces the user and can be touched by the user after the mask is installed on the water heater.

[0056] The connector 9 is specifically a metal sheet with magnetism. In order to have better magnetic adsorption force, the connector 9 has a certain thickness. In order to adapt to the shape and bending angle of each panel of the mask, the connector 9 is processed into an irregular shape that adapts to the shape of the mask. The surface of the connector 9 is provided with three protrusions 11, and the shape, size, position and spacing of the protrusions 11 match the through holes 8 opened on each folded edge. During installation, the protrusions 11 are inserted into the corresponding through holes 8, and then the magnetism of the connector 9 is used to adsorb to the inner surface of the folded edge to achieve fixation. In this way, there is no need to weld or screw the folded edges, which avoids deformation and collapse caused by heat during welding, or uneven surface due to screws, which affects the appearance.

[0057] The mask assembly 1 of the water heater can overcome the internal stress of the mask formed by bending by matching the protrusion 11 on the connecting piece 9 with the through hole 8 of the mask folded edge, so as to limit the side panel 3 from flattening toward the flat front panel 2, so that the mask maintains the bending angle. The connecting piece 9 is fixed to the mask by magnetic adsorption to prevent the connecting piece 9 from falling off the mask, so that the mask can maintain the bending angle and structural shape, and since there is no need for welding or additional parts such as screws between panels in different directions and between folded edges, the overall strength of the mask is improved and the flattening trend of the mask is curbed. The frequency of use of screws and welding is reduced, defects such as deformation and collapse are avoided, and the aesthetics are improved.

[0058] There are many ways to connect the connector 9 to the mask without causing deformation or collapse, not limited to magnetic adsorption. In other embodiments, if the connector 9 is made of non-magnetic material, the connector 9 and the mask can also be connected by interference fit between the protrusion 11 and the through hole 8, and / or, the protrusion 11 passes through the through hole 8 and is connected to the fastener on the opposite side of the connector 9, both of which can achieve the connection between the connector 9 and the mask without falling off.

[0059] In this embodiment, the mask is folded into three panels, each of which has a folded edge at the top and bottom. However, in other embodiments, depending on the structure of the water heater main body, the mask connected thereto may only have a front panel 2 and a side panel 3, but no transition panel 4, and accordingly, the number of protrusions 11 and through holes 8 may be reduced accordingly. Alternatively, for a better connection effect, multiple through holes 8 may be provided on each folded edge, and the number of protrusions 11 may be increased accordingly on the connector 9.

[0060] In this embodiment, since the material of the connector 9 is a magnetic material, the protrusion 11 and the through hole 8 are clearance-matched. Since the connector 9 is connected to the mask by magnetic adsorption, that is, the connector 9 does not need to be interference-fitted with the protrusion 11 and the through hole 8 or other matching methods, it can be connected to the mask and maintain the bent shape; on this basis, the protrusion 11 and the through hole 8 are clearance-fitted, which facilitates the assembly operation between the connector 9 and the mask.

[0061] Among them, Figure 2 and Figure 5 As shown, the mask assembly 1 also includes an elastic member 12, which is specifically a spring, connected to the two connectors 9 on both sides of the mask, forming a tensioning force (tensioning force direction D is perpendicular to magnetic adsorption force direction C) perpendicular to the magnetic adsorption force (magnetic adsorption force direction C is the installation direction of the connector 9 and the mask), so that the protrusions 11 of the connectors 9 on both sides are tightly fitted with the through holes 8 along the tensioning force direction, and the friction force generated ensures that the connector 9 will not fall off. In this way, when the magnetism of the connector 9 declines and the magnetic connection force is insufficient, the connectors 9 on both sides of the mask can be effectively kept firmly connected to the mask, which improves the aesthetics while also improving the connection reliability.

[0062] Among them, Figure 5 As shown, the connector 9 is attached to the inner side of the mask, and the edge 10 of the connector is attached to the fold line between the first folded edge 5 and the front panel 2, and the fold line between the second folded edge 6 and the side panel 3. The edge 10 of the connector is attached to the two fold lines, so that the edge 10 of the connector can limit the flattening of the bent front panel 2 and the side panel 3, and more reliably maintain the bent structural shape.

[0063] Among them, Figure 4 As shown, the first folded edge 5 is spaced from the second folded edge 6. During assembly, the bending angles between different panels of the mask are easily adjusted, and after bending, the different panels tend to be flattened, and the tension generated can improve the reliability of the connection between the connector 9 and the mask.

[0064] The edge of the connector 9 extending toward the inner cavity of the mask does not exceed the edge of the first folded edge 5 and the second folded edge 6 extending toward the inner cavity of the mask, thus maintaining the beautiful edge of the folded edge, which is beneficial to the appearance of the mask.

[0065] Among them, Figure 4 and Figure 6 As shown, the height of the protrusion 11 is greater than the depth of the through hole 8, and the portion of the protrusion 11 protruding from the through hole 8 is used to connect with other components of the water heater, thereby improving the connection strength between the mask and other components. In other embodiments, the height of the protrusion 11 may also be no greater than the depth of the through hole 8, so as to keep the surface of the folded edge smooth and beautiful.

[0066] Among them, Figure 3 and Figure 4 As shown, the three protrusions 11 connected to the first folded edge 5, the second folded edge 6 and the third folded edge 7 are not on the same straight line, which can improve the connection strength, reduce the possibility of deformation, and thus improve the reliability of maintaining the bending shape.
