The drive structure then can adopt an electric telescopic handle, and this electric telescopic handle is connected with the one end of deep bead 2, so can stimulate deep bead 2 and pull open and draw in along a direction, and then realize the regulation of degree air intake aperture.
In order to save installation space, at the same time, the area occupied by the wind deflector 2 when it is open is reduced. The wind deflector 2 includes at least two fan-shaped plates 21 stacked on each other, the number of the fan-shaped plates 21 is specifically set according to the requirement, and the fan-shaped plates in this embodiment are provided with three. The three fan blade plates are folded together, are opened in a fan shape when being opened, and further can cover the air inlet of the fan 1, the opening degree of the fan blade plates is different, and the areas covering the air inlet of the fan 1 are also different, so that the opening degree of the air inlet of the fan 1 is adjusted, and the difference of the input air quantity into the gas water heater is adjusted.
An arc-shaped guide groove 3 is arranged on the shell of the fan 1 or the inner wall of the shell, and a guide piece 4 which can be matched and placed in the guide groove 3 is connected to the outer edge of each sector plate 21. The guide member 4 in this embodiment is a small cylinder, and the guide member 4 and the guide groove 3 are engaged with each other to guide the rotation of the louver board.
The driving mechanism 5 in this embodiment includes a motor 51, a transmission shaft 52, and at least two driving disks 53 sleeved outside the transmission shaft 52, wherein each driving disk 53 is connected to one sector plate 21, the transmission shaft 52 is connected to a driving end of the motor 51, and the driving disks 53 are drivingly connected to the transmission shaft 52. When the fan blades rotate, the fan-shaped opening of the fan blades can be realized only by the rotating speed of each fan blade or different rotating time points, and the driving rotating speed of the motor 51 to the transmission shaft 52 is fixed, so that the orderly unfolding of the fan blades can be realized by the arrangement of the connection mode of the driving disc 53 on the transmission shaft.
If the connection mode can be adopted: each driving disk 53 is screwed on the transmission shaft 52, and the transmission shaft 52 is provided with threads with different screw pitches corresponding to each driving disk 53, and the threads with different screw pitches are respectively matched with the rotation angles of the sector plates 21. In this way, when the motor 51 drives the transmission shaft 52 to rotate, the rotation speeds of the driving disks 53 are different under the driving of the transmission shaft 52. Thereby realizing the unfolding and folding of the three fan blade plates.
In this embodiment, the driving disks 53 are axially spaced outside the transmission shaft 52, the diameters of the driving disks 53 are sequentially increased in the axial direction, the driving disk 53 with the smallest diameter is screwed on the transmission shaft 52, and the outer circumferential wall of the driving disk 53 with the smaller diameter and the inner circumferential wall of the driving disk 53 with the larger diameter in two adjacent driving disks 53 are provided with teeth 531 capable of being engaged in a matching manner.

The core content of the combustion control method of the gas water heater in the embodiment is as follows: and controlling the wind shield 2 to move according to the combustion state of the current gas water heater and the external wind pressure state, and further adjusting the opening of the air inlet of the fan 1 to realize the adjustment of the air inlet amount of the gas water heater. When the gas water heater is controlled, under the condition that the normal combustion work of the gas water heater can be ensured through the rotation speed adjustment of the fan 1, the rotation speed of the fan 1 is usually adjusted firstly, and the control of flameout, ignition failure and matching of the water outlet temperature and the set temperature is avoided. However, when the gas water heater is used, the adjustment of the rotating speed of the fan 1 in the gas water heater is in a range, when the rotating speed of the fan 1 reaches the maximum rotating speed value of the fan 1, the rotating speed of the fan 1 cannot be adjusted upwards, and if the water outlet temperature does not reach the set temperature and the rotating speed of the fan 1 reaches the maximum rotating speed of the fan 1, the rotating speed of the fan 1 cannot be adjusted upwards. When the rotating speed of the fan 1 is at the minimum rotating speed of the fan 1 and the low-pressure condition occurs, the rotating speed of the fan 1 needs to be adjusted downwards continuously. The rotating speed of the fan 1 can not be adjusted to change the air inlet volume, and at the moment, the opening of the air inlet of the fan 1 needs to be adjusted, so that the air inlet volume is adjusted.
The combustion control method of the gas water heater in the embodiment specifically comprises the following steps:

if so, then S2 is performed.
S2, comparing Q with target heat load data Q0 corresponding to the current set temperature; if Q is more than or equal to Q0, the current heat load can reach the target heat load, namely the current gas supply pressure is normal, and if Q is less than Q0, the current heat load can not reach the target heat load, namely the current gas supply pressure is too low;
comparing the V with the normal wind pressure data V0; if V is larger than V0, judging that the external wind pressure is too large, otherwise, judging that the external wind pressure is normal;
s3, if Q is larger than or equal to Q0 and the external wind pressure is too large, supplying power to the motor 51 to drive the wind shield 2 to rotate, further adjusting the covering area of the wind shield 2 on the air inlet of the fan 1, and adjusting the wind shield 2 to enable the opening of the air inlet of the fan 1 to be A;

when the gas water heater leaves a factory, the wind shield 2 is arranged on the air inlet of the fan 1 to enable the air inlet of the fan 1 to keep a fixed opening, namely the initial setting opening, and the opening of the air inlet can ensure that the gas water heater can work normally under most conditions; if Q is in the normal fluctuation range of Q0, the position of the wind shield 2 is kept, so that the opening degree of the air inlet of the fan 1 is the initial setting opening degree, namely the wind shield 2 does not need to be driven to rotate and adjust;
if the Q is more than Q0, and the outside wind pressure is normal, and the current rotating speed of the fan 1 is reduced to the minimum rotating speed, which usually occurs in summer, the inlet water temperature is too high, so that the outlet water temperature is still higher than the set temperature under the condition that the gas water heater works at the minimum gas quantity and the minimum rotating speed of the fan 1, at the moment, the opening degree of the air inlet of the fan 1 can be properly reduced, and the adjustment of reducing the air inlet quantity is realized through the adjustment of the wind shield 2;
if Q is less than Q0 and the external wind pressure is normal, supplying power to the motor 51 to drive the wind shield 2 to rotate, and further adjusting the covering area of the wind shield 2 on the air inlet of the fan 1, and adjusting the wind shield 2 to enable the opening of the air inlet of the fan 1 to be C;
if Q is less than Q0 and the external wind pressure is too large, the motor 51 is powered to drive the wind shield 2 to rotate, so that the covering area of the wind shield 2 on the air inlet of the fan 1 is adjusted, and the opening of the air inlet of the fan 1 is D by adjusting the wind shield 2;
wherein A > B > C > D.
According to the gas water heater and the combustion control method thereof, the wind shield 2 capable of opening and closing relative to the wind inlet is arranged on the wind inlet of the fan 1, so that the opening degree of the wind inlet is changed through the action of the wind shield 2 relative to the wind inlet, and further the regulation of the wind inlet amount in the gas water heater is realized. Especially, under the condition that the rotating speed of the fan 1 is regulated to the limit value and cannot be regulated any more, the wind shield 2 can supplement and regulate the air intake, and the normal operation of the gas water heater is ensured. In the use of gas heater, the condition that low pressure burning appears is more, also can't guarantee through reducing 1 rotational speed of fan that the gas heater appears under the condition of flame-out, then can avoid appearing flame-out or the condition that the point does not catch fire through the regulation of this deep bead 2, has solved a pain point of using among the current gas heater.
The existing wind shield 2 is fixedly installed on an air inlet of the fan 1, and due to the fact that the abnormal combustion time period of the gas water heater is short, after-sales personnel are required to adjust the installation position of the wind shield 2 under the conditions that the combustion is abnormal and the combustion is recovered to be normal, the labor cost is high, and the operation is very troublesome. The wind shield 2 can be opened and closed under the driving of the driving mechanism 5, and the opening of the air inlet is automatically adjusted, so that on one hand, the manual maintenance cost is saved, the problem of abnormal combustion can be solved more quickly, and on the other hand, the early-stage experiment development work of a product designer on the gas water heater is facilitated.
