Abstract

The utility model relates to a kitchen ventilator controller with temperature and infrared ray double-sensing, which comprises a sensor installed on the kitchen ventilator body, and a corresponding control circuit of a start/stop circuit of the kitchen ventilator fan connected with the output of the sensor. The sensor can be a temperature sensor arranged in a sealed casing. The sensor is fixed and arranged on the inner bottom cover body of the kitchen ventilator, and the inner bottom cover body slants to a hearth and is not easy to be covered by oil fume. The utility model can overcome the defect existing in the prior art that a fume sensing head can be covered by oil fume and loses the fume sensing function. The fan can automatically open, and the rotating speed of the fan can be adjusted according to the amount of oil fume. Meanwhile, the utility model also has the functions of displaying the time, prompt, fan state, etc.

Description

Temperature infrared line dual sensing Hood Controller

The utility model relates to a kind of controller that can solve the startup of lampblack absorber sense cigarette effectively, reliably.

The use of lampblack absorber is popularizing of ten minutes, and starting or stoping of general lampblack absorber mostly is manually to finish, because the inconvenience of the limitation of manual control and use, and make people begin to produce some lampblack absorber control device that start from dynamic cigarette.But the following problem of existing this class device ubiquity:

1, under the air port that the sense cigarette end is provided with, though solved the sense cigarette problem of oil smoke, but in the short period of time, the sense cigarette end tends to be stuck with paste by thick oil smoke, thereby effect that can't air flue sense cigarette need could operate as normal through the cleaning of building, be for easy to use originally therefore, reduce the purpose of work and used, so instead increased many unnecessary work contents from dynamic cigarette device.

2, the sense cigarette end is placed on and is difficult for then can only being played effect to general leakage, and can't the oil smoke of cooking being responded to by the oil smoke cover residence, therefore affects this control device and plays a role.

3, the control circuit structure is single, can not show situation, the fan condition of sense cigarette, time of use or the like, alarm.

The purpose of this utility model is to provide a kind of temperature infrared line dual sensing Hood Controller, it can overcome in the prior art that the sense cigarette end is covered by oil smoke and the deficiency that loses the sense hood, can open blower fan automatically, and according to the rotating speed of the size adjustment blower fan of oil smoke, the Presentation Function that has contents such as stronger time, prompting, fan condition simultaneously.

The purpose of this utility model is achieved in that a kind of temperature infrared line dual sensing Hood Controller, it comprises the corresponding control circuit of lampblack absorber fan starting/halt circuit that the sensor that is installed on the lampblack absorber body and sensor output connect, wherein said sensor can be the temperature sensor that is arranged in the airtight housing, this sensor card be arranged on the oblique kitchen range top admittedly and the lampblack absorber that is difficult for being covered by oil smoke on the end cover body.

The top of described sensor housing can be transparent material, and the top of housing can be the arc of transparent focusing, also can be provided with infrared ray sensor in the housing.

Described control circuit connects sensor signal by central controller input, and output is by carrying out the amplifying circuit machine control circuit of giving a dinner for a visitor from afar, and output simultaneously also is connected to demonstration, warning circuit.

The utility model is simple and reasonable for structure, and is easy for installation, multiple functional, sense cigarette sensitivity, and action is short lag time, uses reliable, permanent.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is an installation site of the present utility model structural representation;

Fig. 2 installs cross-sectional view for the utility model.

Fig. 3 is circuit theory diagrams of the present utility model.

Referring to Fig. 1,2, the utility model is a kind of temperature infrared line dual sensing Hood Controller, it comprises the corresponding control circuit of the lampblack absorber blower fan 2 startup/halt circuits that the sensor 3 that is installed on the lampblack absorber body 1 and sensor 3 outputs connect, wherein sensor 3 housings can be transparent material, the top of housing 5 can be the arc 4 of focusing, temperature sensor W is set in the housing 5 and infrared ray sensor H is arranged, non-filler between the element in the housing 5, therefore induction is sensitive, the time of control blower fan action is short, and operation is short lag time.This sensor 3 can fix by the cutting ferrule of protecting fixation together on the 1 interior end of the lampblack absorber cover body that is arranged on the oblique kitchen range top and is difficult for being covered by oil smoke.For example be installed in the bottom of blower fan 2 for the lampblack absorber 1 of deep hood type.Because this sensor 3 has temperature-sensing element, so it is not afraid of oil smoke and covers, and need not often change, and has guaranteed the long-term reliability of action.And can be in conjunction with the ultrared size in infrared ray sensing element testing igniting back, so that the control circuit of the strong or weak wind of blower fan is switched in decision.Firepower is big, and then the rotating speed of blower fan improves; When firepower hour, rotation speed of fan reduces, and wind-force diminishes.

As shown in Figure 3, control circuit of the present utility model connects input jointing temp and infrared ray sensor signal respectively by mouth line P6, the P7 of central controller CPU (can adopt chips such as 89C51), the mouth line P24-P19 of CPU connects digital the demonstration and lampblack absorber control circuit button S1-S6 by compound port, can set the duty of lampblack absorber by button S1-S6, simultaneously charactron can show the countdown etc. of for example working, and CPU mouth line P15, P16 carry out the give a dinner for a visitor from afar rotating speed control switching circuit of machine M2 of amplifying circuit P1, P2 by triode in addition.The mouth line P14 of CPU meets buzzer S7 by amplifying triode Q, plays the auditory tone cues effect to certain state.Button S1-S6 and display device BW can be located at the position easy to operate, front of lampblack absorber, and CPU is connected by the output of lead with sensor 3 on the control panel 6.

This circuit CPU can control the size of blower fan output, and can be controlled in 1-2 minute of Guan Huohou, by the output control switching circuit of CPUP15, P16, the rotating speed that changes blower fan makes wind-force by dying down by force to the wind-force of blower fan automatically, shutdown realizes unattended at last.Warning circuit.Owing to adopt the core of advanced CPU, so panel can demonstrate the state of the time of use, current rotation speed of fan, the warning of fault or the like information as controller.
