Abstract
An integrated kitchen range flue fire-retardant device comprises a wind cabinet, and a three-way wind discharge pipe seat; a wind outlet of the wind cabinet is connected with a wind inlet end of the three-way wind discharge pipe seat; a sealing member is disposed at one end of the three-way wind discharge pipe seat facing the wind inlet end; a sealing sheet is disposed in the sealing member and is used for sealing the wind inlet end; the sealing sheet is connected with a mobile iron core of an electromagnet, and a return spring; the electromagnet is electrically connected with a flue flame sensing circuit. After power on, the electromagnet is turned on when no flame is detected by a flue flame detection circuit, and flue gas during operation is discharged smoothly; in a non-operation state or when flame is detected by the flue flame detection circuit, the power supply of the electromagnet is turned off, and the electromagnet is released; the sealing mechanism is reset and closed by the return spring; the flue is closed; and thus the purposes of fire retardance and prevention of backward flowing and flavor channeling of flue gas in a common flue are reached.
Description
Technical field
The utility model relates to integrated kitchen range flue back-fire relief and backstop, especially household integrated stove flue back-fire relief and backstop.
Technical background
At present, when pot interior phenomenon on fire in use appearred in known integrated kitchen range, flame can suck flue, the greasy dirt of the flue inner accumulated of igniting, thereby initiation fire, and the flame that more seriously ignites can spread in the common flue by flue, has potential safety hazard.In addition, when integrated kitchen range used at high residential building, on business altogether flue negative pressure was large and produce flue gas to pour in down a chimney, alter the phenomenon of flavor commonplace.
The utility model content
For overcoming deficiency and the shortcoming of existing integrated kitchen range, integrated kitchen range flue back-fire relief and backstop that the utility model provides can reach improved purpose.
Integrated kitchen range flue fire retardant device comprises wind cabinet 1, air-out base 2, and described wind cabinet 1 air outlet is connected with air-out base 2 air inlet ends, and seal 4 is arranged on an end described air-out base 2, relative with described air inlet end; Be provided for the diaphragm seal 3 of the described air inlet end of shutoff in the described seal 4, described diaphragm seal 3 connects moving iron core and the back-moving spring 5 of electromagnet 7; Described electromagnet 7 is electrically connected with flue flame detection circuit 8, and described flue flame detection circuit 8 is arranged in the flue.
Further, described electromagnet 7 is arranged on seal 4 outsides, and seal 4 is provided with seal cover 6, and the moving iron core of described electromagnet 7 is inserted in behind seal cover 6 and the back-moving spring 5 and diaphragm seal 3 is fixed.
Preferably, described air-out base 2 is selected threeway air-out base.
After the work of energising blower fan, the flue flame detection circuit is opened electromagnet when not detecting flame, and the flue gas in the work can be discharged smoothly; Off working state or when the flue flame detection circuit detects flame, the tripping magnet power supply discharges moving iron core, and utilize back-moving spring that sealing mechanism is resetted and close, the sealing flue, thus reach back-fire relief and prevent that flue gas from pouring in down a chimney, altering the purpose of flavor.
The utility model has the advantages that:
1, improving product security stops flame to enter flue and common flue, eradicates potential safety hazard.
2, do not affect the product smoke absorption effect, and can reliably prevent the common flue flue gas from pouring in down a chimney and produce the phenomenon of altering flavor.

Specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
See accompanying drawing 1 and accompanying drawing 2,
Integrated kitchen range flue fire retardant device comprises wind cabinet 1, air-out base 2, and described wind cabinet 1 air outlet is connected with air-out base 2 air inlet ends, and seal 4 is arranged on an end described air-out base 2, relative with described air inlet end; Be provided for the diaphragm seal 3 of the described air inlet end of shutoff in the described seal 4, described diaphragm seal 3 connects moving iron core and the back-moving spring 5 of electromagnet 7; Described electromagnet 7 is electrically connected with flue flame detection circuit 8, and described flue flame detection circuit 8 is arranged in the flue.
Further, described electromagnet 7 is arranged on seal 4 outsides, and seal 4 is provided with seal cover 6, and the moving iron core of described electromagnet 7 is inserted in behind seal cover 6 and the back-moving spring 5 and diaphragm seal 3 is fixed.Preferably, described air-out base 2 is selected threeway air-out base.
Current collection gas connects as shown in Figure 3, and flue flame detection circuit (8) is electrically connected with electromagnet (7).
Plugged when the flue flame detection circuit detects flame is not opened electromagnet, and the flue gas in the work can be discharged smoothly; Off working state or when the flue flame detection circuit detects flame, the tripping magnet power supply, release magnet, the sealing flue, thus prevent that flue gas from pouring in down a chimney and completely cutting off the transmission of flame, realizes non-return and purpose back-fire relief.
Above-described specific embodiment only is the most brief embodiment of the utility model, and the equivalent arrangements of such as doing according to the utility model claim all should be technology of the present utility model and contains.
