Abstract
The utility model provides a kitchen negative pressure prevention device which comprises an air inlet pipe, and an electric air valve or an air supply pump arranged on the air inlet pipe, wherein one end of the air inlet pipe is connected with the outside; the other end of the air inlet pipe is connected with the upside of a suspended ceiling in a kitchen; and the electric air valve or the air supply pump is linked with a motor of a range hood in the kitchen. When the range hood is started, the electric air valve is opened, and air enters the air inlet pipe to balance air pressure. When the range hood is closed, the electric air valve is closed, the air inlet pipe is closed, and strong kitchen negative pressure during oil fume sucking is avoided finally. Or a micro differential pressure sensor is adopted for detecting inside and outside differential pressure of the kitchen. When the inside and outside differential pressure of the kitchen is a positive value, the electric air valve or the air supply pump is not started; and when the inside and outside differential pressure is a negative value, the electric air valve or the air supply pump is started.
Description
Technical field
The utility model relates to a kind of anti-kitchen negative pressure device.
Background technology
When exhauster for removing kitchen fumes is opened, the air quantity of draining in the short time is too large, and causing air in kitchen is negative pressure, can fill into large quantity of air from other room.Take air-conditioning system in main building, if the flow process disorder of wind system disequilibrium and wind can cause the dewfall phenomenon to occur.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of anti-kitchen negative pressure device, when it is opened at exhauster for removing kitchen fumes, can avoid filling into air from other room.
In order to solve the problems of the technologies described above, the utility model provides a kind of anti-kitchen negative pressure device, and it comprises: blast pipe, be located at Electric air valve or air delivery pump on this blast pipe; Described blast pipe one end is connected in outdoor, and the other end is connected in furred ceiling top between kitchen, the motor linkage of the lampblack absorber in Electric air valve or air delivery pump and described kitchen.
The utility model provides another kind of anti-kitchen negative pressure device, and it comprises: blast pipe, be located at Electric air valve or air delivery pump on this blast pipe, and for detection of the micro-pressure sensor of inside and outside differential pressure between kitchen, and controller; Described blast pipe one end is connected in outdoor, and the other end is connected in furred ceiling top between kitchen; Described micro-pressure sensor is connected with controller, and this controller is for controlling described Electric air valve or air delivery pump action according to the output valve of described micro-pressure sensor.
With respect to prior art, the technique effect the utlity model has is: anti-kitchen of the present utility model negative pressure device, adopt a square blast pipe, and built-in Electric air valve or air delivery pump, blast pipe one end is connected in outdoor, and an end is connected between kitchen in furred ceiling; The motor linkage of lampblack absorber during use in Electric air valve or air delivery pump and described kitchen,, when lampblack absorber starts, Electric air valve is opened simultaneously, and the blast pipe air intake, with equilibrium air pressure.When lampblack absorber is closed, Electric air valve is closed simultaneously, and blast pipe is closed, and has finally avoided the generation of dewfall phenomenon.Or, adopt micro-pressure sensor, detect inside and outside differential pressure between kitchen.When inside and outside differential pressure between kitchen be on the occasion of the time, described Electric air valve or air delivery pump do not start; When indoor and outdoor pressure reduction is negative value, described Electric air valve or air delivery pump start.
The accompanying drawing explanation
In order to clearly demonstrate innovative principle of the present utility model and than the technical advantage of existing product, following two possible embodiment of limiting examples explanation by the described principle of application by means of accompanying drawing.In the drawings:
Fig. 1 is the structure chart of anti-kitchen negative pressure device.
The specific embodiment
As Fig. 1, the anti-kitchen negative pressure device of the present embodiment comprises: blast pipe 1, be located at Electric air valve 2 or air delivery pump on this blast pipe.Blast pipe 1 one ends are connected in outdoor, and the other end is connected in furred ceiling 3 tops between kitchen, the motor linkage of the lampblack absorber 4 in Electric air valve 2 or air delivery pump and described kitchen, and, when lampblack absorber starts, Electric air valve is opened simultaneously, and the blast pipe air intake, with equilibrium air pressure.When lampblack absorber is closed, Electric air valve is closed simultaneously, and blast pipe is closed.
On the basis of described embodiment 1, there is following modification in the present embodiment:
Adopt micro-pressure sensor, detect inside and outside differential pressure between kitchen.When inside and outside differential pressure between kitchen be on the occasion of the time, described Electric air valve or air delivery pump do not start; When indoor and outdoor pressure reduction is negative value, described Electric air valve or air delivery pump start.
Described micro-pressure sensor is connected with a controller, and this controller is for controlling described Electric air valve or air delivery pump action according to the output valve of described micro-pressure sensor.The preferred single-chip microcomputer of controller.
Obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection domain of the present utility model.
