Abstract
The utility model discloses a hood with an air taking-in pipe, which is provided with an integral fume collecting hood. The top part of the integral fume collecting hood is provided with a centrifugal fan oil and smoke pumping device which supplies air to the integral fume collecting hood, an air inlet tube communicated with outdoor space is transversally arranged on the lower edge of the cooking operation opening of the lower part of the fume collecting hood, a valve is arranged on the air inlet tube, and a plurality of air supplying holes which point to the cooking operation opening are arranged on the air inlet tube. The hood with an air taking-in pipe can automatically supply air and increase oil and smoke pumping rate without reducing indoor temperature in winter.
Description
The utility model relates to a kind of monoblock type fume cupboard that has making-up air device.
Chinese patent 87202458, and 89203454 disclosed stove exhausters, solved the problem of kitchen fume pollution preferably, this class lampblack absorber all has the totally enclosed type seal closure, centrifugal blower and overhang-door mechanism, kitchen range are placed in the seal closure, make that the oil smoke of cooking is firm to be discharged from outdoor once can not producing seal closure.Can not only get rid of oil smoke, also the kitchen be played the effect of ventilation, can be discharged to indoor hot-air outdoor in summer.But temperature is lower in the winter time, and door and window is closed in the room, and the indoor-outdoor air exchange is not smooth, when lampblack absorber starts, is easy to cause indoor and the interior lack of air of seal closure, thereby the smoke pumping rate is descended.
The purpose of this utility model is to provide a kind of oil pumping fume chamber that can overcome lack of air in indoor and the seal closure.The purpose of this utility model is to realize like this, there is its top of monoblock type exhaust fume collecting hood that the centrifugal blower fume exhaust device is housed, the horizontal air inlet pipe with outdoor UNICOM in cooking operation mouth lower edge, exhaust fume collecting hood bottom, air inlet pipe is provided with valve, and offers the tonifying Qi hole that several point to the cooking operation mouth.When weather is warmmer, valve closing can should be played the effect of ventilation to the kitchen, purify the air of a room.When using the utility model in the winter time, should be with valve open, when the lack of air in the exhaust fume collecting hood, outdoor cold air will be by the tonifying Qi hole tonifying Qi in exhaust fume collecting hood on the air inlet pipe, and the oil smoke that produces in the exhaust fume collecting hood will be discharged outdoor with cold air.Can not cause the decline of indoor temperature.
For making tonifying Qi even, can be on horizontal air inlet pipe two arms of UNICOM again, this arm is positioned at the exhaust fume collecting hood two side.
Therefore, the utility model has than prior art can replenish fresh air automatically, does not reduce in the winter time under the condition of indoor temperature, improves the advantage of smoke pumping rate.
Below in conjunction with drawings and Examples the utility model is described further.

Referring to accompanying drawing 1 and Fig. 5, the utility model has one to do framework by aluminium alloy extrusions 10, the exhaust fume collecting hood 1 that glaze 9 constitutes on it, the oily fume exhauster 2 that centrifugal blower constitutes is installed at its top, a horizontal air inlet pipe 3 is located on the cooking operation mouth base, bottom of exhaust fume collecting hood, this pipe passes wall and outdoor UNICOM, at indoor section a butterfly valve 4 is housed, the flow area of pipe is suitable with the centrifugal blower inlet area, have the row air admission hole 5 of 30 millimeters of totally 20 φ on the tube surface, (referring to Fig. 2), in the oblique exhaust fume collecting hood of the discharge directions in tonifying Qi hole, and horizontal plane angle is best between 45 °-75 °.
Embodiment shown in Figure 3, be on main air inlet pipe again 6, two arms of two arms of UNICOM be distributed in biside plate place in the exhaust fume collecting hood 1, the position in the tonifying Qi hole on the main air inlet pipe is identical with embodiment one with direction, the tonifying Qi hole 5 on the arm is exhaust vertically upward.
Embodiment shown in Figure 4 is suspended on exhaust fume collecting hood cooking operation mouth top to air inlet pipe 8, and fixing with exhaust fume collecting hood 1 by boatswain chair 7, tonifying Qi hole perforate direction and horizontal plane angle are advisable between-45 °-75 °.
Transportation for convenience and installation, exhaust fume collecting hood of the present utility model is designed to modular construction, referring to Fig. 5, Fig. 6, Fig. 7, Fig. 8, this exhaust fume collecting hood is assembled into framework 1 by aluminium alloy extrusions 10 and connector 16, glass 9 is installed all around, and glass inner side is compressed by the backstop nail 11 that can insert on the aluminium alloy extrusions, and this backstop nail is plastic products, top is the flanging of elasticity bowl-type, the bottom is a solid post, and the two decentraction is when it inserts in the hole of aluminium alloy extrusions, rotate an angle again, just glass can be compressed.Framework 1 is removable to be three rectangle frames, seven single-piece section bars, and promptly the top frame 12,13 two of side frames, and single- piece 14,15, the plug of plastics connector 16 is all left in wherein three rectangle frames and single-piece section bar connection place.The purpose of doing like this is convenient to dwindle the volume of packing case.
