Abstract
The utility model relates to a connection structure of an air outlet for a kitchen ventilator, which comprises a check valve, an air outlet flange of a fan, and a sealing ring, wherein the air outlet flange of a fan is connected with the check valve; the sealing ring is positioned between the check valve and the air outlet flange; the inner circular edge of the air outlet flange is provided with a sunk annular edge. The lower end of the check valve is provided with a circle of a sealing lip or a plurality of circles of sealing lips which press the sealing ring on the annular edge. The connection structure of an air outlet for a kitchen ventilation through the arrangement of a sunk platform on an original air outlet flange enables oily soil on the inner wall of the check valve to flow downwards to the sunk platform of the air outlet flange along the inner wall. Because the sunk platform is provided with a sealing washer, the connection surface has favorable air tightness, and most oily soil continues to flow into a fan along the inner side of the sunk platform on the air outlet flange of the fan and does not leak out. The number of the sealing surface of the connection structure of an air outlet is reduced from two to one, and one sealing washer is decreased. Besides, the rigidity of the sealing surface is greatly improved, and the leakage of oil fume is effectively avoided.
Description
Technical field
The utility model relates to range hood, is specifically related to the syndeton of range hood air outlet, particularly a kind of improvement of adopting the range hood air outlet syndeton that check (non-return) valve and fan outlet flange directly cooperate.
Background technology
The syndeton of currently used range hood air outlet is: the fan outlet flange is connected with the range hood roof box is inboard, check (non-return) valve is connected with the range hood roof box outside more then, adopt the shortcoming of this syndeton to be: promptly to have twice to connect sealing surface, the chance that causes oil smoke to reveal easily will use two seal washers to connect.
The utility model content
The technical problems to be solved in the utility model is, a kind of syndeton of range hood air outlet is provided, and can overcome above-mentioned shortcoming of the prior art, makes the syndeton of air outlet simpler, and anti-oil smoke is revealed better effects if.
The technical scheme that the utility model provides is: the syndeton of constructing a kind of range hood air outlet, comprise check (non-return) valve, and described check (non-return) valve the fan outlet flange, the sealing ring between described check (non-return) valve and described air outlet flange that are connected, it is characterized in that, described air outlet flange is provided with heavy stand, and the lower end of described check (non-return) valve is provided with described sealing ring is pressed in circle of one on the heavy stand or multi-turn sealing lip limit.
The air outlet syndeton of the range hood that enforcement the utility model provides; By on former air outlet flange, heavy stand being set, greasy dirt from the check (non-return) valve inwall flows to the heavy stand of air outlet flange downwards along inwall, owing on heavy stand, be provided with seal washer, make the composition surface have good air-tightness, overwhelming majority greasy dirts continue in the fan outlet flange heavy stand in the side inflow blower fan inner chamber, and do not leak, the utility model not only reduces to the sealing surface of air outlet syndeton to be had only together from twice, reduced by a seal washer part, and, make the rigidity of sealing surface do bigger raising, can stop oil smoke and reveal.

Fig. 1 is the decomposition diagram of syndeton of the present utility model when being connected with roof box;
Fig. 2 is the decomposition diagram of syndeton when being connected with blower fan;
Fig. 3 is that the master of syndeton looks cutaway view;
Fig. 4 is a syndeton partial enlarged drawing shown in Figure 3.
The specific embodiment
As shown in Figure 1 and Figure 2, the air outlet syndeton of the range hood that is provided is provided with a fan outlet flange 2 of being with heavy stand, is used for blower fan installing and fixing on range hood roof box 3, flange 2 can adopt drawing processing, and the rigidity of flange 2 is improved; In the middle of the composition surface of fan outlet flange 2 and check (non-return) valve 5, be provided with sealing ring 4, be provided with a circle or multi-turn in the lower end of check (non-return) valve 5 seal washer 4 is pressed in lip limit on the heavy stand, two circle lip limits are set usually, and this check (non-return) valve 5 is fixed on fan outlet flange 2 tops by screw 6.
As shown in Figure 3, Figure 4, on roof box, be provided with and be used for the platform that raises up that is connected with air outlet flange 2, be connected by the flange of screw with the raised platforms inner groovy with check (non-return) valve 5 at the end face of air outlet flange 2.
When the greasy dirt on condensing upon check (non-return) valve 4 inwalls flows to the air outlet flange heavy stand place of blower fan 1 downwards along inwall, because seal washer 4 is arranged, there is good air-tightness on composition surface herein, overwhelming majority greasy dirts can continue side inflow blower fan 1 inner chamber in fan outlet flange 2 heavy stands, and do not leak, because the particularity of sheet metal five metals product, 3 very possible poor sealings that the part occurs of fan outlet flange 2 heavy stands and check (non-return) valve, and cause a small amount of greasy dirt flows to fan outlet flange 2 along the poor sealing place of part heavy stand in the outer part, but at this moment because heavy stand (the fan outlet flange of the range hood on the existing market does not have this heavy stand) has certain height, greasy dirt can't be more further to other local leakage.Thereby having reached, total stops the purpose that greasy dirt is revealed.
Claims (3)
1, a kind of syndeton of range hood air outlet, comprise check (non-return) valve, the fan outlet flange that is connected with described check (non-return) valve, the sealing ring between described check (non-return) valve and described air outlet flange, it is characterized in that, the interior ring limit of described air outlet flange is provided with the ring-type limit that sinks, and the lower end of described check (non-return) valve is provided with described sealing ring is pressed in circle of one on the described ring-type limit or multi-turn sealing lip limit.
According to the described syndeton of claim 1, it is characterized in that 2, the lower end of described check (non-return) valve is provided with two circle sealing lip limits.
3, according to claim 1 or 2 described syndetons, described air outlet flange is arranged in the inner groovy of roof box.
