Description

Multichannel family expenses ventilation blower

The utility model belongs to the device, particularly family expenses ventilation blower that ventilates through ducting system with blower fan.

The family expenses ventilation blower that is used for kitchen, toilet, parlor, bedroom has so-called ventilation fan, kitchen hood etc.Ventilation fan in the prior art, kitchen hood because suction mechanism is single ventilation function, effect poor, be difficult to drain the oil smoke gas the kitchen in, also difficult can a tractor serves several purposes eliminating room in the waste gas of each room, unless each room installs respectively.In the room of device common flue, also there is back the defective of cigarette in existing kitchen hood.

The purpose of this utility model is to provide a kind of and can more effectively drain the kitchen oil flue gas for addressing the above problem, and can a tractor serves several purposes gets rid of the multichannel family expenses ventilation blower of other room's waste gas in the room.

The technical solution of the utility model multichannel family expenses ventilation blower is to be provided with exhaust fume collecting hood and blower fan, its special character is that described blower fan is the rear-mounted blower fan that is installed in the air-out port, between exhaust fume collecting hood and air-out port, lead to an air volume distributor is arranged, air volume distributor has an air outlet and a main inlet scoop and offers secondary inlet scoop, be connected with ventilation duct on the secondary inlet scoop, the ventilation duct other end is connected with secondary suspended hood, and the exhaust fume collecting hood rear is provided with the main air door in the air channel, is provided with secondary air door in the secondary inlet scoop.

Get rid of for the waste gas that can be suitable for more rooms, the quantity N of the secondary inlet scoop of this ventilation blower is 1≤N≤5, and correspondingly, the quantity N of described ventilation duct, secondary suspended hood, secondary air door respectively is 1≤N≤5.

This ventilation blower respectively is combined with one in described main air door, secondary air door one side and drives the motor that air door opens and closes.

The utility model multichannel family expenses ventilation blower is owing to be provided with air volume distributor, offer secondary inlet scoop on the air volume distributor and be connected with ventilation duct on it, the ventilation duct other end is connected with the secondary suspended hood that can be installed on relevant position, kitchen, so this ventilation blower is compared with existing range hood, can more effectively get rid of the oil smoke gas that generates in the kitchen, for example the waste gas of the top of the cookers such as micro-wave oven except that main kitchen range generation.Because it is a plurality of that secondary inlet scoop and secondary suspended hood can have, so this ventilation blower except getting rid of the kitchen oil flue gas, also can be got rid of the waste gas of other rooms in the room, accomplishes a tractor serves several purposes.This ventilation blower can be installed on the metope of nearly exhaust outlet, so have the little characteristics of noise because blower fan is rear-mounted.This ventilation blower also owing to be provided with main air door and secondary air door, close when ventilation blower is not worked by these air doors, so this ventilation function stops in the smoke backflow inlet chamber of common flue.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model multichannel family expenses ventilation blower one structural representation;

Fig. 2 is this ventilation blower main air door, secondary air door and drive motor means schematic diagram thereof;

Fig. 3 is this ventilation blower electrical schematic diagram.

Mark, symbology among the figure: 1 flue or metope, 2 rearmounted blower fans, 3 air volume distributors, 4 (elasticity) tube connector, 5 exhaust fume collecting hoods, 6 main air doors, 7-1,7-2, the secondary inlet scoop of 7-3,8-1,8-2, the secondary air door of 8-3,9-1,9-2, the secondary suspended hood of 9-3,10-1,10-2,10-3 ventilation duct, but 11 corner panels, 12 rotating shafts, 13 either-rotation motors; The DZ-illuminating lamp, K _ZD-luminous lamp switch, K _A-main air door forward and backward switch, K _B, K _C, K _DBe respectively secondary air door 8-1, secondary air door 8-2, secondary air door 8-3 forward and backward switch, K _X90 ° of forward and reverse limit switches of-major and minor air door, K _T-blower fan 2 speed-regulating switch, K ₄-four-point switch, M ₁The single-phase variable speed electric motors, particularly of～-blower fan 2, M _SThe single-phase low-speed bidirectional motor of-driving main air door and secondary air door is a motor 13.

Embodiment 1 multichannel family expenses ventilation blower is provided with an air volume distributor 3, and its air outlet is connected in the air-out port that can be installed on metope or common flue 1, and a rear-mounted blower fan 2 is installed in the air-out port.Offer secondary inlet scoop 7-1, secondary inlet scoop 7-2, secondary inlet scoop 7-3 on the air volume distributor and be connected with ventilation duct 10-1, ventilation duct 10-2, ventilation duct 10-3 respectively on it, the other end of these ventilation ducts is connected with secondary suspended hood 9-1, secondary suspended hood 9-2, secondary suspended hood 9-3 respectively, and air volume distributor front end air inlet is connected with a tube connector 4 its front ends and is connected with exhaust fume collecting hood 5.Air quantity distributes front inner wall to be provided with main air door 6, is respectively equipped with secondary air door 8-1, secondary air door 8-2, secondary air door 8-3 in the described secondary inlet scoop.The keying of described main air door and secondary air door drives through single-phase low-speed bidirectional synchronous motor 13, illustrates as Fig. 2.These air doors are provided with the rotatable central rotating shaft that opens and closes, and cooperate through worm screw, fly worm gear and rotate, and be equipped with 90 ° of limit switches of rotation.But exhaust fume collecting hood is provided with a corner panel 11 its upper end pivots is connected in rotating shaft 12.This ventilation blower circuit theory as shown in Figure 3.This multichannel family expenses ventilation blower can be installed in the kitchen, room, and described air-out port is fixed in exterior wall or common flue towards an indoor side, and blower fan 2 is installed in it.Exhaust fume collecting hood is installed on main kitchen range top, and a secondary suspended hood wherein is installed on one top, kitchen as secondary suspended hood 9-1---and nearly backstairs top can be loaded on for closed kitchen, exterior window top, nearly kitchen can be loaded on for worn-out open type kitchen.Other secondary suspended hood can be installed on top, relevant room in the room respectively, and the ventilation duct that links to each other with secondary suspended hood can secretly place in the furred ceiling of top, room or rotation angle position.

When kitchen in the room or relevant room need ventilate, can open corresponding main air door and/or secondary air door, open blower fan 2 then and ventilate.Referring to Fig. 3, open K switch _A, K _B, K _C, K _DAny one or a plurality ofly just changeing end S to motor 13, this moment air door synchronous motor M _SJust change, air door opens to 90 ° through described limit switch action, cuts off the electricity supply, and air door is positioned the full open shape, opens K switch then successively ₄, K _T, blower fan 2 rotates and ventilates.If will stop to ventilate, with K _A, K _B, K _C, K _DMiddle respective switch pushes counter-rotating end R, corresponding motor M _SAir door is closed in counter-rotating, cuts off the electricity supply the motor stall when air door is closed fully under the limit switch effect.With K _A, K _B, K _C, K _DSwitch all pushes counter-rotating end R, and corresponding motor is all reversed, and motor power is closed and cut off to all air doors.Because counter-rotating end R and K ₄Be in the open circuit shape, KT is a dead electricity, and blower fan stops operating, and avoids air volume distributor to be in negative pressure state, damage air door and relevant controlling organization.
