Embodiment Construction
[0029] see figure 1 According to the present invention, a blast type gas cooker includes a body, a burner mounted on the body, a gas valve body, a control circuit and a blast fan mounted on the burner, and the blast fan It is an ordinary 12V DC fan, installed on the mixing tube of the burner, and blows the external air into the mixing tube to form a mixed gas of gas and air, thus facilitating combustion. The gas valve body includes components such as a solenoid valve and an ignition switch, which are used to control gas on-off and ignition, and the flow of gas can be adjusted through the knob on it, thereby adjusting the size of the flame. These structures can all adopt conventional mechanical structures. The present invention is mainly aimed at the improvement of the control circuit, and the following will mainly describe the control circuit.
[0030] see figure 1 , in the present invention, the control circuit includes a main control circuit 1, a gas flow detection circuit...

An air blowing type gas stove comprises a body, a burner, a blower fan, a gas valve body and a control circuit, wherein the control circuit comprises a main control circuit, a gas flow rate detection circuit, an air quantity control circuit, a flame detection circuit, a solenoid valve control circuit, an air quantity adjustment and storage circuit, an ignition circuit and a power supply circuit; and an air quantity adjustment key is arranged on the body. The air blowing type gas stove has the following advantages that the air quantity adjustment and storage circuit is additionally arranged in the gas stove and can adjust the rotating speeds of the fan corresponding to all flow rates through the key at random according to the practical situations of an air source used by a user, increase the air quantity and also reduce the air quantity, so that the rotating speeds of the fan under all the flow rates adapt to the used air source, and the new rotating speed can be automatically written into the storage circuit to replace the original rotating speed; and as a flow rate tachometer in the storage circuit is updated, a new flow rate tachometer is used for work in the future, so that the difference problem of the air source is solved.
Description
technical field [0001] The invention relates to a blast type gas stove, in particular to an intelligent blast type gas stove with a control system. Background technique [0002] Household gas stoves have already entered our kitchens. When ordinary gas stoves are burning, in addition to providing air to the burners inside the stove, secondary air is also required on the upper part of the burner to ensure full combustion of the gas. Due to the need for secondary air, the distance between the pot and the burner is limited. If it is too close, the secondary air will be insufficient, yellow flames will appear, and carbon monoxide will exceed the standard. However, if the distance is long, part of the heat of combustion is radiated to the surrounding air, resulting in a decrease in thermal efficiency. The thermal efficiency of ordinary gas stoves is generally between 50% and 55%, so that nearly half of the energy will be wasted, which does not meet the requirements of the current...
