Description

Technical Field

[0001] The invention relates to the field of gas stove technology, and in particular to a wind-fire integrated synchronous control system of a commercial high-fire stove. Background Art

[0002] Traditional commercial high-fire stoves have a central high-pressure high-fire nozzle in the center to achieve the effect of high-fire gas combustion. However, due to safety issues and the upgrade of national standards, the central high-pressure high-fire nozzle and other structures cannot be used. The market has changed to adding a blower in the stove to actively blow air to achieve the effect of high fire. It usually includes a gas valve, a burner assembly, a blower and a blower controller. In order to match the control of the blower and the gas valve, the market usually has the following two controls:

[0003] One is that the blower and the gas valve body are controlled independently of each other, and the operation process needs to independently control the wind power and fire power of the two, which is difficult to control.

[0004] Another method is to set a rotary potentiometer on the gas valve body, and judge the angle of the control lever by rotating the potentiometer to control the firepower corresponding to the rotation angle and adjust the wind force of the blower accordingly. However, the control ignition process of the gas valve is usually to press down the control lever and rotate it to the maximum fire position, and then trigger the ignition structure to ignite; at this time, the blower wind force corresponding to the maximum fire position is also the maximum value, and the air volume is too large, which will make the burner ignition process very difficult and the ignition success rate is low. Therefore, further improvement is needed. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a wind-fire integrated synchronous control system for a commercial high-fire stove.

[0006] The technical solution adopted by an embodiment of the present invention to solve the technical problem is: a wind-fire integrated synchronous control system for a commercial fierce fire stove, including a gas valve body, a burner assembly, an ignition assembly, a blower and a control center:

[0007] The gas valve body includes a valve stem and a potentiometer; the potentiometer can detect the rotation angle of the valve stem and feed back an electrical signal of the rotation angle to the control center;

[0008] During the rotation of the valve stem, the identification point of the potentiometer corresponds to the conduction state of the gas valve body to set three control identification points, namely, the fire state point, the maximum fire state point and the minimum fire state point; in the rotation path of the valve stem, the maximum fire state point is set between the fire off state point and the minimum fire state point;

[0009] The wind-fire integrated synchronous control system comprises the following steps:

[0010] S1, in the off state, the identification point of the valve stem and the potentiometer is at the off state point; the control center determines that the high-fire stove is in the standby state at this time;

[0011] S2, press down the valve stem, rotate the valve stem along the first rotation direction, and the valve stem approaches the maximum fire state point from the fire-off state point; the control center records the rotation angle change process fed back by the potentiometer during the rotation process as the ignition start state K1; when the valve stem approaches the maximum fire state point, the valve stem can trigger the ignition component to perform the ignition operation; in the ignition start state K1, the control center can control the blower to be in the off state or the low wind force ignition blowing state;

[0012] S3, after entering the ignition start state K1, after the set time T1, the control center switches to the fierce fire burning state K2; in the fierce fire burning state K2, the control center controls the wind force of the blower according to the rotation angle of the valve stem; the closer the identification point of the potentiometer is to the maximum fire state point, the greater the wind force of the blower.

[0013] Optionally, the high-fire stove is also provided with a flameout detection probe electrically connected to the control center; the flameout detection probe can detect whether there is a flame at the fire end of the burner head assembly, and feed back to the control center; when the flameout detection probe determines that there is no flame at the fire end of the burner head assembly, the control center's control over the blower will switch from the high-fire burning state K2 back to the ignition start state K1.

[0014] Optionally, the ignition assembly is a pulse ignition structure, including a pulse ignition micro switch; when the valve stem is pressed down, when the valve stem rotates to the maximum fire state point, the pulse ignition micro switch can be triggered for ignition, and the control center starts timing the set time T1.

[0015] Optionally, the first rotation direction is counterclockwise.

[0016] Optionally, the maximum fire state point is set at a midpoint between the fire off state point and the minimum fire state point.

[0017] Optionally, the fire-off state point and the minimum fire state point are set at 180 degrees.

[0018] Beneficial effects of the present invention: the control center sets three control identification points, namely, the fire state point, the maximum fire state point and the minimum fire state point, according to the ignition process of the gas valve body and the identification point of the potentiometer corresponding to the conduction state of the gas valve body; first, when in the fire-off state, the control center identifies it as a standby state; then, during the ignition process, the valve stem is pressed down, and during the process of rotating the valve stem along the first rotation direction, the rotation angle change process fed back by the potentiometer is recorded as the ignition start state K1, in which the blower is in a shutdown or low-wind-force ignition and blowing state, with no blowing or only low-wind-force blowing. At this time, the ignition component can ignite more efficiently and is not easy to extinguish; after the delay protection of the set time T1, the control center switches to the fierce fire burning state K2, at which time the control center controls the wind force of the blower according to the rotation angle of the valve stem; the closer the identification point of the potentiometer is to the maximum fire state point, the greater the wind force of the blower, and the wind force and vitality can realize the integrated synchronous control of the gas valve body. The wind-fire integrated synchronous control system of the commercial high-fire stove of the present invention can maintain simple wind-fire synchronous integrated operation control while maintaining a high ignition success rate. The user control operation is simple and the ignition success rate is high.

[0032] The wind-fire integrated synchronous control system includes the following steps:

[0033] S1, in the off state, the identification point of the valve stem 11 and the potentiometer 12 is at the off state point 60; the control center 50 determines that the high-fire stove is in the standby state at this time;

[0034] S2, press down the valve stem 11, rotate the valve stem 11 along the first rotation direction, and the valve stem 11 approaches the maximum fire state point 61 from the fire-off state point 60; the control center 50 records the rotation angle change process fed back by the potentiometer 12 during the rotation process as the ignition start state K1; when the valve stem 11 approaches the maximum fire state point 61, the valve stem 11 can trigger the ignition component 30 to perform the ignition operation; in the ignition start state K1, the control center 50 can control the blower 40 to be in the off state or the low wind force ignition blowing state;
