Technical Field
[0001] The utility model relates to the technical field of gas water heaters, in particular to a primary air adjustment plate structure which is convenient for debugging a primary air coefficient of a water heater. Background Art
[0002] Gas water heater products with strong drum structure such as Figure 5 As shown in FIG. 1 , due to the influence of the fan 100 , the uniformity of the ratio of primary air to secondary air required for combustion of different fire bars is poor. Usually, a primary air adjustment plate needs to be added to adjust the amount of primary air required for combustion of different fire bars, that is, the primary air coefficient. Common primary air adjustment plates are as follows: Figure 4 As shown, the primary air injection holes 101 corresponding to each fire bar are different, and need to be adjusted according to the characteristics of the fire bar and the actual combustion state. This adjustment process is not successful in one go, and the size of each fire bar injection hole needs to be adjusted repeatedly to achieve the best combustion state of each fire bar. However, the problem is that the primary air injection holes 101 need to be adjusted repeatedly, that is, repeated proofing and testing are required, which wastes time and cost, and the debugging effect is still difficult to achieve the best state.
[0003] In addition, experienced performance engineers usually draw a rough sketch of a primary air conditioning panel based on their experience, make a prototype of the primary air conditioning panel, and then use aluminum foil to seal the size of each primary air injection hole 101 to achieve the purpose of adjusting the primary air injection amount, and then simulate and calculate the size and shape of each hole, and re-produce the primary air conditioning panel to shorten the time and cost of performance debugging; but the shape of the aluminum foil plugging cannot be guaranteed to be exactly the same as the re-produced shape, that is, the performance parameters of the re-produced sample will inevitably differ from the performance parameters of the aluminum foil plugging.
[0004] Therefore, further improvements are necessary. Utility Model Content
[0005] The utility model aims to provide a primary air conditioning plate structure which is simple in structure, convenient to adjust, low in cost, high in adjustment efficiency and strong in practicality and is convenient for debugging the primary air coefficient of a water heater, so as to overcome the shortcomings of the prior art.
[0006] A primary air conditioning plate structure designed for this purpose is convenient for debugging the primary air coefficient of a water heater, characterized in that it includes a primary air conditioning plate frame and multiple adjustment rings, the primary air conditioning plate frame is provided with multiple air injection holes, the air injection holes correspond one-to-one to the injection holes of the single fire bar, the adjustment ring is provided with an adjustment inner hole, the shape and size of the adjustment inner hole of each adjustment ring are different, and each adjustment ring can be replaceably placed on each air injection hole to adjust the shape and size of the actual air injection hole of the primary air conditioning plate by adjusting the inner hole.
[0007] The shapes and sizes of the air ejection holes on the primary air conditioning panel frame are the same.
[0008] The outer dimensions of the adjusting ring are the same as those of the air ejection hole.
[0009] The outer dimensions of each adjusting ring are the same.
[0010] The shape and size of the air ejection holes are larger than the shape and size of the ejection holes of the single fire bar.
[0011] The outer dimensions of the adjusting ring are larger than the outer dimensions of the ejection holes of the single piece of the fire bar.
[0012] Each adjustment ring can be placed arbitrarily in all the air ejection holes of the primary air adjustment plate frame.
[0013] The number of adjustment rings is 10 or more.
[0014] The air ejection holes are linearly arranged on the primary air conditioning panel frame.
[0015] The shapes of the adjusting ring and the adjusting inner hole are circular or elliptical.
[0016] The utility model divides a primary air conditioning plate into a primary air conditioning plate frame and an adjusting ring. The corresponding air injection holes on the primary air conditioning plate frame are all designed to have the same shape and size. The air injection holes are usually enlarged in proportion to the shape of the injection holes of the corresponding fire bars. At the same time, similar ring-shaped adjusting rings with different adjusting inner hole shapes and sizes are made. The outer dimensions of these adjusting rings are required to be made according to the shape and size of the air injection holes on the primary air conditioning plate frame, and the adjusting inner holes are made into different shapes and sizes as required. These adjusting rings are used to adjust the size of the actual primary air injection holes of each fire bar, that is, to adjust the flame height and combustion performance of each fire bar, so that the primary air conditioning plate after mold opening is almost exactly the same as the primary air conditioning plate corresponding to the experiment, and the flame height and combustion performance of each fire bar are also almost exactly the same as the performance of the debugging prototype, which completely solves the time waste and cost waste problems of repeated proofing and debugging, and makes primary air conditioning very convenient, fast and accurate.

The adjusting ring 2 is provided with an adjusting inner hole 4, and the shape and size of the adjusting inner hole 4 of each adjusting ring 2 are different from each other. Each adjusting ring 2 can be replaceably placed on each air introduction hole 3, so as to adjust the shape and size of the actual air introduction hole 6 of the primary air conditioning plate 5 by adjusting the inner hole 4. Finally, the effect of the primary air conditioning plate 5 after mold opening is exactly the same as the effect of the implementation test.
[0024] The shapes and sizes of the air ejection holes 3 on the primary air conditioning panel frame 1 are the same.
[0025] The outer dimensions of the adjustment ring 2 are the same as those of the air injection holes 3. Even if the shapes and dimensions are different, it is only a positive or negative tolerance. Different adjustment rings 2 can be placed arbitrarily in all the air injection holes 3 of the primary air conditioning plate frame 1, and the gap is very small.
[0026] The outer dimensions of the adjustment rings 2 are the same.
[0027] The shape and size of the air injection hole 3 are slightly larger than the shape and size of the injection hole of a single fire bar, so that a certain fire bar can meet the maximum primary air demand.
[0028] The outer dimensions of the adjusting ring 2 are slightly larger than the outer dimensions of the ejection holes of the single piece of the fire bar.
[0029] Each adjustment ring 2 can be placed arbitrarily in all the air ejection holes 3 of the primary air conditioning plate frame 1 .

[0033] Method for debugging the primary air coefficient of a gas water heater:
[0034] 1) Make a primary air conditioning panel frame 1, on which the air injection holes 3 are completely consistent, and the outer dimensions of each air injection hole 3 are slightly larger than the outer dimensions of the injection holes on the fire bar, so that a certain fire bar can meet the maximum primary air demand;
[0035] 2) Make adjustment rings 2 with different sizes and shapes of the inner holes 4, requiring that the outer dimensions of these adjustment rings 2 are completely consistent with the shape and dimensions of the air injection holes 3 on the primary air conditioning plate frame 1, that is, these adjustment rings 2 can be seamlessly placed in each air injection hole 3 of the primary air conditioning plate frame 1 to achieve the purpose of changing the size of the injection hole;
[0036] 3) Carefully observe the flame height and shape of each fire row, adjust the size of the adjusting inner hole 4 of the adjusting ring 2 corresponding to each fire row one by one, and repeatedly replace the adjusting ring 2 to achieve the best flame height and combustion performance of each fire row, so as to form the final shape and size of the adjusting inner hole 4 corresponding to each fire row. Assuming the result is as follows Figure 2 As shown;
