Referring to fig. 1, a gas-heating water heater 100 according to an embodiment of the present invention includes a housing 1 and a display panel 2 connected to each other, and the display panel 2 includes a display screen and a mounting plate 21, and the display screen is fixed to the mounting plate 21. The housing 1 and the display panel 2 together form the entire appearance of the gas heating water heater 100. The housing 1 and the display panel 2 enclose an equipment accommodating cavity.
The gas-fired water heater 100 further includes a burner, a heat exchanger, an ignition device, a pneumatic control device, a water-gas linkage device, and a control device. The combustor, the heat exchanger, the air control device, the water-gas linkage device and the control device are all arranged in the equipment accommodating cavity. The water control device comprises a water pump, a control water valve and the like.
The working process of the gas heating water heater 100 is as follows: after the heating start button is pressed, a water pump in the water control device is started to push heating water to flow. When the pressure of the heating water is stabilized at a normal level, the water-gas linkage device opens the gas control device again to enable gas to enter the combustor, the ignition device is controlled to ignite, the combustor starts to burn, and the heating water entering the heat exchanger is heated, so that the heating purpose is achieved.
The housing 1 may be a rectangular parallelepiped as shown in fig. 1. Referring to fig. 1, 5 and 6, the housing 1 is formed by splicing a housing front panel 11, a housing top panel 12, a housing bottom panel 13, a first housing side panel 14, a second housing side panel 15 and a housing back panel 16. The front housing panel 11 and the display panel 2 are located on the same side, and the front housing panel 11 and the display panel 2 are both disposed opposite to the back housing plate 16. The display panel 2 is located below the housing front panel 11. The total area of the housing front panel 11 and the display panel 2 is equal to or close to the area of the housing back panel 16. The first and second casing side plates 14 and 15 are respectively located on both sides of the casing front panel 11 in the horizontal direction. The housing top plate 12 is disposed opposite the housing bottom plate 13.
Referring to fig. 7 and 8, a first buckle 111 is formed by bending inward the left and right sides of the front panel 11 of the housing. The two first buckling plates 111 are respectively parallel to the first shell side plate 14 and the second shell side plate 15. The lower edge of the front panel 11 of the housing is bent inwards to form a first flange 112. The front panel 11 of the housing needs to be bent at least twice to form a first buckling plate 111 and a first flanging 112 respectively, and because the housing 1 generally adopts a sheet metal part, the sheet metal part can rebound when being bent, so that the bending angle alpha of the first flanging 112 cannot form a required 90-degree right angle, but the rebound is a condition that the bending angle alpha is greater than 90 degrees. Therefore, when the housing front panel 11 and the display panel 2 are spliced, after the first flange 112 of the housing front panel 11 contacts the display panel 2, the display panel 2 is pushed downwards by the first flange 112 of the housing front panel 11, so that the gap between the housing front panel 11 and the display panel 2 is large, and the flash seam problem occurs.
In order to solve the problem of the flash seam at the joint of the housing front panel 11 and the display panel 2, referring to fig. 9, in the display panel 2 of the embodiment of the present application, a connecting rib 211 is formed at the upper edge of the inner wall of the mounting plate 21. The connecting rib 211 abuts against the first flange 112 of the front panel 11 of the housing, and the width of the connecting rib 211 is smaller than that of the first flange 112. Both the width direction of the connecting rib 211 and the width direction of the first flange 112 are the direction W shown in fig. 12. The mounting plate 21 may be a plastic member.
Compared with the prior art, the display panel 2 in the embodiment of the present application is in contact with the first flanging 112 of the front panel 11 of the housing through the connecting rib 211, and because the width of the connecting rib 211 is smaller than the width of the first flanging 112, the contact area of the joint of the display panel 2 and the housing 1 is smaller, and the first flanging 112 of the front panel 11 of the housing is close to the edge region and does not need to be in contact with the display panel 2. Therefore, a deformation space can be left for the first burring 112 of the case front panel 11. Thus, the first flange 112 of the front housing panel 11 is prevented from pushing the display panel 2 open, so that the gap S shown in fig. 2 is formed at the joint of the front housing panel 11 and the display panel 21And the size is small, so that the flash seam problem is reduced.
Based on the above, in the gas-heating water heater 100 according to the embodiment of the present invention, the first flange 112 is provided with the first connection hole 1121 as shown in fig. 8. A first connecting plate 212 located below the connecting rib 211 is formed on the inner wall of the mounting plate 21 at a position close to the upper edge, a second connecting hole 2121 shown in fig. 12 is formed in the first connecting plate 212, and the second connecting hole 2121 corresponds to the first connecting hole 1121. The gas heating water heater 100 further includes a first fastening member 3 as shown in fig. 9, and the first fastening member 3 is inserted into the first connection hole 1121 and the second connection hole 2121 to press the mounting plate 21 against the housing front panel 11. This application embodiment compresses tightly display panel 2' S mounting panel 21 and shell front panel 11 through first fastener 3, has further reduced the gap S1 of the concatenation department of shell front panel 11 with display panel 2, is favorable to solving the flash seam problem here. It should be noted that the first fastening member 3 may be a bolt or a screw.
In order to facilitate the detachment and installation of the first fastening member 3, so as to facilitate the maintenance, the lower edge of the display panel 2 in the embodiment of the present application is bent inward to form the second turned edge 213 as shown in fig. 9, a third connecting hole is formed on the second turned edge 213, and the third connecting hole corresponds to the second connecting hole 2121. The first fastening member 3 sequentially penetrates through the third connecting hole, the second connecting hole 2121, and the first connecting hole 1121, that is, the first fastening member 3 penetrates through the inner side of the display panel 2 from the outer side of the bottom of the display panel 2 through the third connecting hole as shown in fig. 1, then penetrates through the display panel 2 through the second connecting hole 2121, and finally is fixedly connected to the first connecting hole 1121. From the above, one end of the first fastening member 3 is located at the outer side of the bottom of the display panel 2, so that the first fastening member 3 can be conveniently dismounted and mounted by an operator from the outer side, and the operation is more convenient. And, hidden design can be realized to first fastener 3, and the outward appearance is better.
Considering that the width of the housing front panel 11 (the width direction is the direction K shown in fig. 1) is large, if only one fastener is used, both the housing front panel 11 of the sheet metal member and the mounting plate 21 of the plastic member are easily deformed in the width direction. Therefore, in some embodiments of the present application, the first fastening member 3 may be plural.
The two first fastening members 3 shown in fig. 1 are spaced apart from each other along the extending direction of the second flange 213 (the extending direction of the second flange 213 is parallel to the width of the front panel 11 of the housing), so that the connection strength between the mounting plate 21 of the display panel 2 and each region of the front panel 11 of the housing in the width direction is improved, and the gaps at the positions where the front panel 11 of the housing and the display panel 2 are spliced in the width direction are smaller and more uniform.
The cross section of the connecting rib 211 may be rectangular, or may be a right trapezoid as shown in fig. 12. Taking the cross section of the connecting rib 211 as a right trapezoid as an example, referring to fig. 10 to 12, the surface of the upper bottom 2111 of the connecting rib 211 abuts against the surface of the first flange 112 of the front panel 11 of the housing, and the width of the upper bottom 2111 of the connecting rib 211 is equal to the width of the upper bottom 2111 of the connecting rib 211W1Less than the width W of the lower base 2112 of the connecting rib 2112. The connecting rib 211 with the right trapezoid cross section can meet the requirement that the contact area of the first flanging 112 of the shell front panel 11 is small, the size of the connecting rib 211 is large, the structural strength of the connecting rib 211 is high, and the connecting rib 211 is convenient to process.
If the width W of the upper bottom 2111 of the connecting rib 2111Smaller than the thickness D of the front panel 11, the abutting area between the connecting rib 211 and the first flange 112 of the front panel 11 is too small, and the difficulty of manufacturing the connecting rib 211 by opening the mold is high. Therefore, in the embodiment of the present application, the width W of the upper bottom 2111 of the above-described tie-bar 2111Equal or nearly equal with the thickness D of shell front panel 11, can guarantee that link bar 211 and first turn-ups 112 support to intensity, the size of link bar 211 is suitable, and the degree of difficulty of die sinking preparation link bar 211 is less. For example, the thickness D of the front panel 11 of the housing is 1mm, and the width W of the upper bottom 2111 of the bead 2111Also 1 mm.
The lower edge of the first fastening plate 111 is formed with a third flange 1111 as shown in fig. 8. The left side and the right side of the mounting plate 21 are respectively bent inwards to form second buckling plates 214 as shown in fig. 13, and the two second buckling plates 214 are respectively arranged in parallel with the two first buckling plates 111. Connecting rib 211 extends to the upper edge of second buckle 214, and connecting rib 211 abuts against third flanging 1111. Similarly, the connecting rib 211 abuts against the third flanging 1111, so that the gap S shown in fig. 3 at the joint of the first buckle plate 111 and the second buckle plate 214 can be reduced2。
The first and second housing side plates 14 and 15 need to be connected to the display panel 2. The first flange 112 of the front panel 11 of the housing shown in fig. 8 is bent downward to form a mounting leg 113, and a first mounting hole 1131 is opened on the mounting leg 113. A second connecting plate is formed on the first shell side plate 14 (and/or the second shell side plate 15) close to the shell front panel 11, and a second mounting hole is formed on the second connecting plate. The gas-fired heating water heater 100 further includes a second fastening member, which is inserted into the first mounting hole 1131 and the second mounting hole. Likewise, the second fastener may also be a bolt or screw.
In order to prevent the mounting leg 113 and the second fastening member from lifting up the mounting plate 21, in the embodiment of the present application, an escape groove 215 as shown in fig. 9 is formed in the mounting plate 21 at a position corresponding to the mounting leg 113, and the escape groove 215 can escape from the head of the mounting leg 113 and the head of the second fastening member connected to the mounting leg 113.
In addition to the above-mentioned problem of flash seams at the joint of the display panel 2 and the front panel 11 of the housing, the problem of plane deviation between the outer surface of the display panel 2 and the outer surface of the front panel 11 of the housing may also occur.
In order to avoid the problem of plane deviation between the outer surface of the display panel 2 and the outer surface of the front panel 11 of the housing, in some embodiments of the present application, the gas-heating water heater 100 further includes a first limiting structure 216 as shown in fig. 9, the first limiting structure 216 is disposed on the mounting plate 21, and the first limiting structure 216 abuts against the edge of the first flange 112. The first limiting structure 216 can limit the position of the outer surface of the display panel 2 in the direction perpendicular to the mounting plate 21, so that the outer surface of the display panel 2 and the outer surface of the front housing panel 11 are on the same plane as much as possible, and the problem of tolerance between the outer surface of the display panel 2 and the outer surface of the front housing panel 11 can be avoided.
The first limiting structure 216 may only include one limiting element, or may include a plurality of limiting elements. Similarly, referring to fig. 9, 14 to 16, the plurality of stoppers 2161 are disposed on the first connecting plate 212 and distributed at intervals along the length direction (the direction P in fig. 9) of the first connecting plate 212. The plurality of stoppers 2161 can limit the installation position of the display panel 2 in the direction perpendicular to the installation plate 21 at a plurality of positions in the length direction of the first connection plate 212, and ensure that the outer surface of the display panel 2 is flush with the outer surface of the housing front panel 11.
Based on the above, the structure of the limiting member 2161 may be various, such as L-shaped, solid cylindrical, and U-shaped. For example, the limiting member 2161 shown in fig. 9 is U-shaped, and the U-shaped edge of one side of the limiting clip is connected to the surface of the first connecting plate 212, so that the structure is simple, the material consumption is low, and the cost is low.
However, since the mounting plate 21 of the display panel 2 is a plastic member, it is necessary to manufacture it by using a mold. Thus, it is possible to provideIn the process of opening the actual mounting plate 21, the width W of the first flange 112 is adjusted3The distance L from the outer surface of the display panel 2 to the surface of the limiting member 2161 closest to the outer side is designed to be equal to, and due to manufacturing errors, the outer surface of the display panel 2 is higher than the outer surface of the front panel 11 of the housing after the display panel 2 is mounted. Therefore, in the present embodiment, the width W of the first cuff 1123Is smaller than the distance L from the outer surface of the display panel 2 to the surface of the position-limiting member 2161 closest to the outer side, so as to avoid the problem of plane aberration caused by manufacturing error. In the assembly stage, the distance L is adjusted by applying glue so that the outer surface of the display panel 2 is adjusted to a position on the same plane as the outer surface of the housing front panel 11.
Similarly, in order to avoid the problem of plane deviation between the first fastening plate 111 and the second fastening plate 214, the mounting positions of the two second fastening plates 214 of the mounting plate 21 in the display panel 2 need to be limited. In some embodiments of the present application, referring to fig. 9 and 18, the gas-heating water heater 100 further includes a second stopper 217, the second stopper 217 is disposed on an inner wall of the mounting plate 21, and the second stopper 217 abuts against the first and second housing side plates 14 and 15, respectively. Second limit structure 217 can be through leaning on respectively with first shell curb plate 14, second shell curb plate 15, has restricted the mounted position of the surface of second buckle 214 to the plane tolerance problem of second buckle 214 with first buckle 111 has been reduced.
The second limiting structure 217 may be a limiting barrier strip or a limiting rib plate. Taking fig. 19 as an example that the second limiting structure 217 is a limiting rib 2171, the limiting rib 2171 can not only limit the installation position of the second gusset 214, but also improve the structural strength of the installation plate 21. Similarly, the second stop structure 217 includes two stop ribs 2171, and the two stop ribs 2171 are respectively located at the left and right sides of the inner wall of the mounting plate 21, as shown in fig. 19.
The housing bottom plate 13 of the gas heating water heater 100 according to the embodiment of the present application is rotatably connected to the mounting plate 21 of the display panel 2. After the first fastening member 3 is removed, the display panel 2 can be rotated downward to open to expose the internal components, so that the complete machine does not need to be disassembled, and the after-sales maintenance of the components in the gas heating water heater 100 is facilitated.
In some embodiments, the housing base 13 and the mounting plate 21 of the display panel 2 may be directly connected by a hinge.
In other embodiments, referring to fig. 4, 17, 20 to 22, the housing bottom plate 13 is fixedly provided with a mounting bracket 4, the mounting bracket 4 is provided with a mounting leg 41, and the mounting leg 41 is provided with the fixing shaft 5.
