Problems solved by technology

But it has the following disadvantages: 1. The gas sensor is close to the stove and is easy to be greasy with oily smoke, which reduces the sensitivity or fails, and makes it lose its protection function in a short time
In addition, the corrosive effect of oil fume makes the life of the gas sensor shorter
2. The gas induction controller device is set on the range hood body, which is inconvenient to maintain
Since the above shortcomings have not been resolved for a long time, more than 90% of the range hoods currently on the market do not have safety protection functions
Due to the inconvenience of installing the gas induction controller and the difficulty of maintenance, the exhaust fan rarely has this safety protection function

Embodiment Construction

[0014] The present invention will be described in further detail below in combination with three embodiments and accompanying drawings. Embodiment 1 of the present invention is shown in Fig. 1-1 and Fig. 1-2. The gas induction controller does not include the gas element combination 5 including the transformer, the circuit board 4, and the gas sensor 7 are arranged in the casing 3, and the wire 2 is a six-core sheathed wire, and three cores are used for electrical connection with the power plug 6 To transmit single-phase three-wire AC power to the body 1 circuit, the cross-sectional area of ​​each core is 0.75mm 2 (The power of the electrical appliances that can be used is 0.4-2mm 2 Choose between) copper conductors. Wherein the two cores transmit the voltage of the circuit power transformer in the body 1 to the gas sensor to provide working voltage for it, which can greatly reduce the volume of the gas induction device arranged on the power line. The controlled element of t...

Abstract

The present invention discloses a power line with gas-sensing device. It is mainly used on the exhaust equipment, and is characterized by that the partial element and device of the gas-sensing controller are combined or whole gas-sensing controller is mounted on the power line so as to solve the problem of that the gas-sensing element of the gas-ensing controller of kitchen ventilator is near to stove and can be blocked easily by fume to make the gas-ensing element lose its protection function and shorten its its service life. Said invention raises its safe and protection function.

Description

technical field [0001] The invention relates to a special power cord, especially a power cord with a gas induction device. technical background [0002] Existing air exhaust equipment, such as range hoods, exhaust fans, etc., uses a power cord consisting of a single-phase three-wire plug and a wire electrically connected to it, and its function is to transmit single-phase three-wire alternating current to the electrical appliance body circuit. The gas induction controller installed on the range hood is arranged on the range hood body. Such as commercially available: Jinbaili CXW-200-228A, Shuaikang CXW-180-2388, Yuli CXW-180-2000K, etc., which have the function of automatically starting the pumping unit and sound and light warning when it senses the leakage of gas . But it has the following disadvantages: 1. The gas sensor is relatively close to the stove and is easily stuck by oily smoke, which reduces the sensitivity or fails, and loses its pr...
