Abstract

The utility model discloses the smoking control circuit of a kind of smoke exhaust ventilator, it is characterized in that this oil pumping control circuit includes control switch, the first catalyst, the second catalyst and relay, it is characterised in that: the input of the outfan series connection cut-in relay of described catalyst；The outfan series connection of relay accesses the input of the second catalyst, and is directly connected with circuit zero line.This oil pumping control circuit can be effectively reduced energy consumption by the circuit composition of self, does not affect original smoking exhaust effect simultaneously.

Description

A kind of smoking control circuit of smoke exhaust ventilator

Technical field

This utility model belongs to the technical field of smoke exhaust ventilator, particularly to logical smoke exhaust ventilator convulsion circuit.

Background technology

Smoke exhaust ventilator has become the requisite gizmology of Modern Family, and but, better instrument also to be cleared up often Cleaning, otherwise, of long duration not only can form grease and affect the environmental health in kitchen, but also making of lampblack absorber can be affected With, make oil smoke be difficult to get rid of.

During the use of smoke exhaust ventilator, it has been found that the smoking effect of smoke exhaust ventilator is asks the most serious Topic, the power height of smoking can improve the effect of smoking, but also bring increasing considerably of power consumption, and for advocating energy-conservation fall The modern home appliance of consumption, this becomes a drawback；Smoking for low-power consumption controls, although energy consumption is little, but brought Side effect is that the smoking effect of smoke exhaust ventilator is greatly lowered, and often leaves substantial amounts of oil smoke deposition in smoke exhaust ventilator, Affect the use of smoke exhaust ventilator.

Summary of the invention

For solving the problems referred to above, the purpose of this utility model is to provide the smoking control circuit of a kind of smoke exhaust ventilator, should Oil pumping control circuit can be effectively reduced energy consumption by the circuit composition of self, does not affect original smoking air draft effect simultaneously Really.

Another purpose of the present utility model is to provide the smoking control circuit of a kind of smoke exhaust ventilator, and this oil pumping controls electricity Line structure is simple, be easily achieved, and can be widely applied in present smoke exhaust ventilator.

For achieving the above object, the technical solution of the utility model is as follows.

A kind of smoking control circuit of smoke exhaust ventilator, it is characterised in that this oil pumping control circuit include control switch, the One catalyst, the second catalyst and relay, it is characterised in that: the input of the outfan series connection cut-in relay of described catalyst End；The outfan series connection of relay accesses the input of the second catalyst, and is directly connected with circuit zero line.

Described controlling switch, include and stop key, start button, stop button series connection accesses in circuit, start button In parallel with one group of normally opened contact of the first catalyst, the second catalyst.

Further, stop key described in, start button and be all connected on live wire.

Further, described first catalyst, the second catalyst are in parallel, and described startup button is parallel with the first catalyst Control switch.

It is in series with the second catalyst before described relay and controls switch.

Described relay is ST3PF type relay.

The beneficial effects of the utility model are:

1, this oil pumping control circuit can be effectively reduced energy consumption by the circuit composition of self, does not affect original simultaneously Smoking exhaust effect.

2, this oil pumping control circuit simple in construction, be easily achieved, can be widely applied in present smoke exhaust ventilator.

Accompanying drawing explanation

Fig. 1 is the circuit diagram of the smoking control circuit that this utility model is implemented.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.

The automatic warm sensing control smoke exhaust ventilator that this utility model is implemented, includes existing circuit and parts, such as, controls Circuit processed, display screen etc., foregoing circuit and parts are technology, do not repeat them here.Its main feature is in addition to should Outside the main functional circuit that some oil pumping are smoked is arranged, also add infrared human body probe control circuit, permissible by this circuit The intelligent opening of hommization or close the operation of lampblack-pumped correlation function, reaches energy-saving and cost-reducing effect.

As it is shown in figure 1, wherein SB1 is stop button, SB2 is start button, and KM1 is the first catalyst, and KM2 is second to connect Tentaculum, KT is relay.

Stop key (SB1), start button (SB2) and be all connected on live wire.

First catalyst (KM1), the second catalyst (KM2) are in parallel, and described startup button (SB2) is parallel with the first contact Device controls switch.

Front second catalyst that is in series with of relay (KT) controls switch.

During work, press start button SB2, the first catalyst KM1 and the second catalyst KM2 simultaneously electric work, work After completing, press stop button SB1, the first catalyst KM1 and quit work, the power-off of relay K T, but relay K T is normally opened to be touched Point still remains closed, and the second catalyst KM2 works on, until the setting time to just quitting work, reaches exhaust fan and takes out Fan starting simultaneously, stops separate purpose.So can be effectively reduced power consumption.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
