Drawings
The application will be better understood in view of the following description (given by way of example only) and with reference to the accompanying drawings, in which:
FIG. 1 shows a perspective view of a flare used in a prior air purification apparatus;
FIG. 2 shows a cut-away side view of a fan and flare used in an air purification apparatus according to the present application;
FIG. 3 shows a perspective view of a flare used in an air purification apparatus according to the present application; and is also provided with
Fig. 4 shows a cross-sectional view of a bell mouth used in an air cleaning device according to the present application.
Detailed Description
Referring to the drawings, the fan 2 and flare used in the prior air cleaning apparatus are shown in longitudinal cross-section along a plane passing through the first axis X (the axis of rotation of the fan 2). The fan 2 is operated such that air is sucked in through an inlet (upper part of the plane in the drawing) and then discharged through an outlet (lower part of the plane in the drawing).
The inlet of the fan 2 has a substantially cylindrical inlet duct 3, the axis of the inlet duct 3 being the first axis X.
The present application relates to an air cleaning device comprising a bell mouth 1, which bell mouth 1 is adapted to be mounted on an inlet pipe 3 of a fan 2. The flare 1 has an open shape when it is far from the fan 2, i.e. it narrows in shape when it is close to the fan 2. Thus, the flare 1 concentrates the air flow entering the fan 2. The smooth and continuous section of which facilitates the air entering the fan 2 of the air cleaning device.
The horn 1 used in the prior air cleaning device is shown in more detail in fig. 1, the horn 1 generally comprising a ring rotating substantially about a second axis Y. When the flare 1 is located at the inlet of the fan 2, the second axis Y merges with the first axis X.
Such a flare 1 preferably has a transverse portion 5, i.e. the transverse portion 5 widens away from the fan 2 according to the portion of the plane passing through the second axis Y. The flare 1 thus forms a funnel which concentrates the air flow into the inlet duct 3.
The transverse portion 5 is generally continuous. It may be curved, preferably circular. As shown, it is still preferably a quarter circle.
According to the embodiment shown, the transverse portion 5 is parallel to the second axis Y at the proximal portion 6 (i.e. as close as possible to the fan 2 and its air inlet duct 3), and the transverse portion 5 is perpendicular to the second axis Y at the distal portion 7 (i.e. furthest from the fan 2). The proximal end portion 6 thus forms a first lip 8, which first lip 8 is substantially cylindrical along the second axis and has a diameter slightly smaller than the diameter of the inlet duct 3. Thus, when the flare 1 is located at the inlet of the fan 2, the first lip 8 is inserted into the intake duct 3.
Prior air cleaning devices appear to generate potential vibrations that interfere with the user. After several attempts, these vibrations are eliminated after adding the flare 1 shown in fig. 2, 3 and 4 to the fan 2.
It thus appears that the vibrations in the prior air cleaning device are caused by parasitic circulation at the interface between the bell mouth 1 and the inlet pipe 3 of the fan 2. This parasitic circulation may be related to re-suction of air at the outlet of the fan 2, which is returned to the fan inlet through the interface between the bell 1 and the inlet pipe 3.
In the air cleaning device according to the present application, the bell mouth 1 comprises a first ring 4 rotating substantially about a second axis Y, which is similar to the bell mouth 1 in the prior air cleaning device. The flare 1 has a curved transverse portion 5 widening away from the fan 2, preferably a circular transverse portion 5, more preferably along a quarter circle, the transverse portion 5 being substantially parallel to the second axis Y at the proximal portion 6 and substantially perpendicular to the second axis Y at the distal portion 7. The proximal end portion 6 forms a substantially cylindrical first lip 8 along the second axis Y, the diameter of the first lip 8 being slightly smaller than the diameter of the inlet duct 3. Thus, when the flare 1 is placed on the intake duct of the fan 2, the first lip 8 is fitted into the intake duct 3.
The bell 1 of the air cleaning device according to the present application now also comprises a second ring 9 rotating substantially about the second axis Y. The second ring 9 is assembled to the first ring 4 in a sealing manner. Thus, no air circulation between the first ring 4 and the second ring 9 occurs when assembled between the first ring 4 and the second ring 9. The second ring 9 forms a second lip 10 at its proximal end. The second lip 10 is substantially parallel to the first lip 8. The second lip 10 has a diameter slightly larger than the diameter of the air inlet duct 3 to cover the air inlet duct 3. Thus, the first lip 8 is inserted into the intake pipe 3 from the inside, while the second lip 10 surrounds and covers the intake pipe 3 from the outside. The interface thus formed between the bell mouth 1 and the inlet pipe 3 forms a bend which prevents air circulation between the inside and the outside of the bell mouth 1, so that such parasitic air circulation can be ended.
Finally, it has been demonstrated that this interface allows parasitic vibrations to be suppressed and also allows an average increase of 4.5% in the additional airflow circulating between the horn mouth 1 and the fan 2 due to the suppression of parasitic circulation.
Such a flare may be made of metal, plastic or composite materials.
According to another feature, illustrated in figures 2 and 3, the second ring 9 is cylindrical. This shape generally simplifies the manufacture of the second ring 9 and its assembly on the first ring 4 by welding or in a moulding process to produce the flare 1 according to the present application.
The size of the flare 1 is determined according to the diameter of the air inlet pipe 3 of the fan 2. According to a first model of the fan 2, the diameter of the air inlet duct 3 is 250mm. Thus, the diameter of the flare 1 is substantially equal to 250mm. The diameter of the first lip 8 is slightly less than 250mm, i.e. 250mm minus 5mm to 10mm, and the diameter of the second lip 10 is slightly greater than 250mm, i.e. 250mm plus 5mm to 10mm.
The diameter of the inlet pipe 3 and the nominal diameter of the bell mouth 1 may be lower or higher, depending on another model of the fan 2. Thus, it may be equal to 280mm or even 310mm, etc.
The present application has been illustrated and described in detail in the drawings and the foregoing description. This must be considered as illustrative and given by way of example and not limiting the present application to the present description only. Many variant embodiments are possible.
