Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation outdoor hood such as a pressure ventilation fan for discharging oil smoke to the outdoors.

[0002]

2. Description of the Related Art In recent years, it has been realized that a ventilator with a pressure is used to discharge oil smoke generated during cooking at a store or the like to the outside, and an outdoor hood for ventilation is used on the outdoor side. There is an increasing demand for an outdoor hood for ventilation that can be manufactured at a low cost.

In the past, when constructing an outdoor hood for ventilation of this type, it was general that the requested contractor went to the construction site and made it by hand.

[0004]

In such a conventional outdoor hood for ventilation, the construction company goes to the construction site to make it by hand, so that there is a problem that it takes time to construct and the cost becomes high. It was

SUMMARY OF THE INVENTION The first object of the present invention is to provide an outdoor hood for ventilation which is easy to construct and is inexpensive.

A second object is to prevent oil in the ventilation outdoor hood from being easily discharged, prevent the oil from flowing indoors or outdoors, and prevent any trouble in the neighborhood.

[0007]

In order to achieve the first object of the outdoor hood for ventilation of the present invention, the first means is to provide a mounting base at one end which is attached to the periphery of the ventilation opening provided in the wall portion. A mounting duct having a square cross section, a first elbow having a square cross section to form a curved section, a joint duct having a square cross section, and a second cross section having a square section at an opening at one end to form a curved section The elbow and the elbow and each duct and the elbow are connected to each other.

In order to achieve the second object, the second means is the first elbow or the second elbow arranged on the lower side.
The elbow is equipped with a removable oil receiver on the lower surface of the outer circumference.

In order to achieve the third object, the third means has a structure in which a half punch portion is formed in the joint duct and the attachment duct.

[0010]

According to the present invention, by the structure of the above-mentioned first means, the mounting duct is mounted on the wall portion at the construction site, and the first duct is sequentially installed.
The elbow, the joint duct, and the second elbow can be connected via the connecting portion to construct the outdoor hood for ventilation.

Further, with the structure of the second means, the oil smoke adhering to the inside of the ventilation outdoor hood is received by the oil pan, and the accumulated oil can be easily removed by removing the oil pan.

According to the structure of the third means, the wire for attaching to the wall or the like for holding the outdoor hood for ventilation so as not to fall by the wind at the time of construction and the hole for attaching the attaching member such as the angle are formed in half. It can be easily formed by punching the punch part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to.

As shown in the drawing, a mounting base 1 mounted around a ventilation opening (not shown) provided on a wall portion has a square cross section having a square cross section, and a leg section having a square cross section. A first elbow 4 formed with a removable oil receiver 3 on the lower surface of the outer periphery and a joint duct 5 having a square cross section
And a second elbow 7 having a square section with a louver section 6 in the opening at one end and forming a curved section.

Then, at each end of the mounting duct 2 and the first elbow 4, and at each end of the joint duct 5 and the second elbow 7, a connecting portion 8 into which the other member to be connected is fitted is provided, and the mounting duct 2 and the joint are provided. A half punch section 9 is provided on the duct 5.

With the above construction, when constructing an outdoor hood for ventilation in the field, the mounting base 1 is mounted around the ventilation opening provided on the wall, and the mounting duct 2 is mounted.
Half punch section 9 provided in the mounting duct 2 if necessary
The mounting duct 2 is punched out and a mounting member (not shown) such as wire is used to hold the mounting duct 2, and the first elbow 4 and the joint duct 5 are joined to each other via the connecting portion 8 and, if necessary, the joint duct 5 The half punch portion 9 is punched out and a fitting material such as wire is used to connect and hold the joint duct 5 to the wall portion or the like.

Then, the second elbow 7 is connected to the joint duct 5 via the connecting portion 8 so that the louver portion 6 faces the front or side surface depending on the direction of ventilation.

In the case of lateral ventilation, as shown in FIG. 2, a third elbow 10 having no oil receiver is horizontally connected to the mounting duct 2 so that the third elbow 10 is substantially horizontal. After connecting the joint duct 5, connecting the first elbow 4 to the joint duct in an upward direction, connecting the joint duct 5 to the first elbow 4, and then connecting the joint duct 5 so that the louver portion 6 faces in the lateral direction. Connect the elbow 7 of 2.

In the case of ventilation in the downward direction, as shown in FIG. 3, the mounting duct 2 is connected downward with the third energy absorber 10 provided with no oil receiver, and the third elbow 10 is connected to the third elbow 10. The fourth elbow 1 in which the joint duct 5 is connected in the vertical direction, and the joint duct 5 is provided with the louver portion 6 and the oil receiver 3
By connecting 1 it is possible to ventilate downward.

As described above, according to the ventilation fan outdoor hood of the embodiment of the present invention, the mounting duct 2 is mounted on the site via the mounting base 1, and the first elbow 4, the joint duct 5,
By connecting the second elbow 7 via the connecting portion 8,
Since the outdoor hood for ventilation can be constructed, the construction on site becomes easy, and since the second elbow 7 has a square cross section, the direction can be easily changed to the front or side.

Further, since the first elbow 4 is provided with the removable oil receiver 3, the oil smoke adhering to the ventilation outdoor hood is collected in the oil receiver 3 and the oil accumulated in the oil receiver 3 is removed. By doing so, it is possible to prevent oil from flowing into the room or from leaking from the outdoor hood.

Further, the mounting duct 2 and the joint duct 5
Since the half punch portion 9 is provided in the, the attachment material such as wire can be easily attached and can be easily held.

[0023]

As is apparent from the above-described embodiments, according to the present invention, a mounting duct having a square cross section with a mounting base mounted at the periphery of a ventilation opening provided in a wall portion,
Each duct has a first energy for forming a curved portion with a square cross section, a joint duct with a square cross section, and a second energy for forming a curved portion with a square cross section with an opening at one end. And since the connection part was provided on the elbow,
It is possible to provide an outdoor hood for ventilation that is easy to construct and inexpensive.

Further, since the oil receiver is detachably provided on the outer peripheral lower surface of the first elbow or the second elbow arranged on the lower side, the oil is prevented from flowing into the room or leaking from the outdoor hood. it can.

Further, since the half punch portion is formed in the joint duct and the mounting duct, it can be easily held by a mounting material or the like.
