Problems solved by technology

But, in the process of realizing the present invention, the inventor finds that there is following problem in the engine-driven generator of prior art: artificially removed CO alarm, the connection lead between CO alarm and ignition device is not connected (such as dropped In any case, such as power failure of the CO alarm, etc., the engine driving the generator can still start or run effectively, so it is difficult to avoid the accumulation of CO in the environment and may cause the occurrence of the aforementioned harmful consequences

Abstract

The present invention provides an improved engine-driven generator which can normally alarm or / and shut down an engine when CO concentration exceeds a standard, and also shut down the engine when a COalarm is removed. The improved engine-driven generator comprises an engine; and the CO alarm which is connected with the engine ignition device and used for detecting the CO concentration in the environment near the engine, generating a signal according to the CO concentration change and sending the signal to the ignition device so as to control the ignition device to ignite, wherein the CO alarmis arranged to send out a flameout signal to enable the ignition device not to ignite when the detected CO concentration is larger than or equal to the preset concentration, or, when the signal transmission is interrupted, the ignition device does not ignite. Based on the same purpose, the invention also provides a control method of the engine-driven generator and also provides the CO alarm.

Description

technical field [0001] The present application belongs to the field of generators, in particular to generators driven by engines. Background technique [0002] Working machines driven by general-purpose engines, such as floor polishers, cleaning machines, generators, etc., when used in relatively closed places such as indoors, basements, storage rooms and other places with relatively poor ventilation, the exhaust gas Carbon monoxide (CO) will diffuse into the working environment where the working machine is located, and when the concentration of CO in the environment accumulates to a certain level, it may cause bodily harm to people in the environment. In order to avoid this kind of hazard, the working machines of the prior art, especially the generators, are equipped with CO alarms, so that when it is detected that the CO in the environment exceeds the set value, an alarm is issued to remind the operator to turn off the engine or / and the CO alarm Directly control the engin...
