Abstract

An automatic kitchen ventilator based on stove magnetic control belongs to the field of household electrical appliances and comprises a stove which is formed by a power supply, a magnetic control switch and a kitchen ventilator. The power supply, the magnetic control switch and the kitchen ventilator are connected through wires, the power supply is installed inside the kitchen ventilator, and the magnetic control switch is arranged on the stove. The magnetic control switch comprises a pressure sensor, a reed switch and a relay. When a pot is placed on the stove, the pressure sensor is pressed, then a magnet of the pressure sensor moves downwards to approach the reed switch so as to conduct the reed switch. The relay supplies electric power to the kitchen ventilator to enable the kitchen ventilator to run after the reed switch is conducted. When the pot is removed from the stove, the magnet separates from the reed switch under the effect of a spring inside the pressure sensor so that the kitchen ventilator is powered down; therefore automatic control of the kitchen ventilator is achieved. The automatic control ventilator can be widely used in families, restaurants and the like, is simple in structure, and can bring convenience to users.

Description

A kind of automatic cooking fume exhauster based on the stove and accessory magnetic control

Technical field

The utility model relates to the smoke exhaust ventilator device of automatic control, especially a kind of automatic cooking fume exhauster based on the stove and accessory magnetic control that opens or closes by stove and accessory control smoke exhaust ventilator.

Background technology

At present, known automatic cooking fume exhauster generally all is to adopt the smoke sensing probe as signal source, and its complex structure is not too sensitive during use, can not accomplish effectively control automatically.

The utility model content

The purpose of this utility model is to overcome existing automatic cooking fume exhauster complex structure, not too sensitive during use, can not accomplish effectively control automatically, provide a kind of simple in structure, use sensitivity, a kind of automatic cooking fume exhauster that can control effectively automatically based on the stove and accessory magnetic control.

The purpose of this utility model is achieved in that

A kind of automatic cooking fume exhauster based on the stove and accessory magnetic control, comprise stove and accessory, it is characterized in that constituting that power supply, magnetic switch and smoke exhaust ventilator are connected by lead by power supply, magnetic switch and smoke exhaust ventilator, power supply is installed in the smoke exhaust ventilator, and magnetic switch is installed on the stove and accessory.

Described power supply is made up of a transformer, four commutation diodes and an electrochemical capacitor, connects by lead therebetween.

Described magnetic switch is made up of a pressure sensor, a tongue tube and a relay, connects by lead between tongue tube and the relay; Pressure sensor is made up of shell, motion bar, spring, contact-making surface and magnet, and motion bar, spring are installed in housings, and contact-making surface is installed in above the motion bar, and magnet is installed in below the motion bar.

Described smoke exhaust ventilator is exactly common commercially available smoke exhaust ventilator.

The utility model utilizes pressure sensor, tongue tube, relay as magnetic switch, pot will be pressed on the pressure sensor when being placed on pot on the stove and accessory, at this moment thereby the magnet of pressure sensor will move down near the tongue tube reed switch conduction, and will power to smoke exhaust ventilator by relay behind the reed switch conduction makes it running; When pot is left stove and accessory, thereby will leave the outage of tongue tube smoke exhaust ventilator, so just accomplish that smoke exhaust ventilator controls automatically at the effect lower magnet of pressure sensor contained spring.Be widely used in family, dining room etc.The utility model features simple structure can bring convenience to the user.

Description of drawings

Fig. 1 is the utility model structured flowchart; Fig. 2 is the utility model circuit diagram; Fig. 3 is the pressure sensor structure schematic diagram of magnetic switch.

The specific embodiment

As shown in fig. 1, a kind of automatic cooking fume exhauster based on the stove and accessory magnetic control comprises stove and accessory, constitute by power supply, magnetic switch and smoke exhaust ventilator, power supply, magnetic switch and smoke exhaust ventilator are connected by lead, and power supply is installed in the smoke exhaust ventilator, and magnetic switch is installed on the stove and accessory.Power supply is made up of a transformer, four commutation diodes and an electrochemical capacitor, connects by lead therebetween.Magnetic switch is made up of a pressure sensor, a tongue tube and a relay, connects by lead between tongue tube and the relay; Pressure sensor is made up of shell, motion bar, spring, contact-making surface and magnet, and motion bar, spring are installed in housings, and contact-making surface is installed in above the motion bar, and magnet is installed in below the motion bar.Smoke exhaust ventilator is common commercially available smoke exhaust ventilator.

As shown in Figure 2, form power supply by transformer T, commutation diode VD1, VD2, VD3, VD4 and electrochemical capacitor C; Form magnetic switch by pressure sensor SN, tongue tube SQ and relay K; M is a smoke exhaust ventilator.After the opening power, the 220V AC power is reduced to 6V through T, through converting dc source to and import SQ after VD1, VD2, VD3, the VD4 rectification C filtering; If at this moment pot is placed on the stove and accessory, because SN is installed on the stove and accessory, so pot will be pressed on the SN, then the magnet of SN will move down the SQ conducting that continues near SQ, K gets electric its normally opened contact closure after the SQ conducting, because M gets on the normally opened contact that a feeder ear is connected K, M will get electric operation like this; When pot is left stove and accessory, thereby the magnet of SN will move up and leaves SQ M outage stall under the effect of SN contained spring, has so just accomplished the automatic control of M.In Fig. 2, it is the 220V/6V transformer of 3W that T adopts power, and VD1, VD2, VD3, VD4 adopt the 1N4001 silicon rectifier diode, and C is that the electrochemical capacitor model is 10V1000UF; SN is a pressure sensor, and SQ is JAC-3 a type normally opened contact tongue tube, and K is 4123 type 6V relays; M is a smoke exhaust ventilator.

As shown in Figure 3, the 1st, shell, the 2nd, motion bar, the 3rd, spring, the 4th, contact-making surface, the 5th, magnet.When being installed in pressure sensor on the stove and accessory, should be the support of the contact-making surface 4 of pressure sensor a little more than stove and accessory, thereby so that when putting pot pot can push down the magnet 5 that contact-making surface 4 drives motion bars 2 and be positioned at motion bar 2 bottoms and move down.

Claims

1. automatic cooking fume exhauster based on the stove and accessory magnetic control, comprise stove and accessory, it is characterized in that constituting, connect by lead between power supply, magnetic switch and the smoke exhaust ventilator by power supply, magnetic switch and smoke exhaust ventilator, power supply is installed in the smoke exhaust ventilator, and magnetic switch is installed on the stove and accessory.
