The housing 110 is formed in a case shape, and may include a box-shaped lower housing 112 and an upper housing 111 covering an upper surface of the lower housing 112. The assembly unit 160 may be formed in a plurality of places above the lower housing 112, and after temporary assembly by placing the upper housing 111 on the lower housing 112, the assembly unit 160 is attached to the upper housing 111. It can be completely assembled by fastening. Conversely, the assembly unit 160 may be fastened to the lower housing 112 from the upper housing 111. The assembly unit 160 will be described later.

The housing 110 may be formed of a porous resin material such as styrofoam or expanded polypropylene (EPP). In this way, when the housing 110 is formed of EPP, etc., the housing 110 can absorb vibrations of the impeller, so even if a separate cushioning material or noise material is not used, vibration of the impeller can be reduced and noise can be reduced. . Therefore, it is easy to install the ventilator compactly in a narrow ceiling space as in the present invention.

In addition, a groove 112a is formed in the lower housing 112 so that the suction unit 120 and the discharge unit 130 can be coupled, and the suction unit 120 and the discharge unit 130 are inserted into the groove 112a. I can.

An installation panel 150 may be formed under the housing 110. It is preferable that the installation panel 150 is formed of a material that is harder than the housing 110 such as metal. This takes into account that when the centrifugal fan 200 or the like is installed in the housing 110, the bolt or the like cannot be fixed as the housing 110 is formed of an EPP material or the like. Therefore, the centrifugal fan 200 may be installed in such a manner as to be bolted to the bolting portion 151 formed on the installation panel 150 with the lower surface of the housing 110 interposed therebetween. This assembly structure is advantageous in compacting the length of the kitchen detachable hood in the vertical direction.

The assembly unit 160 is shown in FIGS. 8 and 9. Referring to this, the upper fixing member 161 inserted and fixed in the hole or groove 161d formed in the upper housing 111 and the lower fixing member inserted in the hole or groove 162d formed in the lower housing 112 and fixed. Including 162, the upper housing 111 and the lower housing 112 may be assembled by fastening the upper fixing member 161 and the lower fixing member 161.

In addition, the upper fixing member 161 and the lower fixing member 162 are fixed bodies 161a and 162a for interviewing the upper housing 111 and the lower housing 112, respectively, and the upper housing 111 and the lower housing 112 It may include insertion protrusions 161b and 162b protruding to be inserted into and extending, and ribs 161c and 162c protruding from the outer circumferences of the insertion protrusions 161b and 162b and extending in the longitudinal direction.

Further, the fastening member is a hinge formed on one of the fixing bodies 163a and 163b in contact with the upper housing 111 and/or the lower housing 112, and the fixing body at any one of the upper fixing member 161 and the lower fixing member 162. A shaft-shaped hinge portion 163c hinged to the branch portion 162e, a connection portion 163d connecting the hinge portion 163c and the fixed body 163a, and an upper fixing member 161 and a lower fixing member 162 It may include a fastening protrusion (163e) fastened to the other of the.

The hinge portions 162e and 163c may be formed in the opposite direction, and the fastening protrusion 163e may be formed as a fastening groove so that the fastening member 163 may be fastened. Further, in the housing 110, a groove (not designated by reference numeral) may be formed at a position corresponding to the end of the fastening member 163 so that the fastening member 163 can be easily opened and closed.

The centrifugal fan 200 is installed such that the impeller 240 has an axial direction perpendicular to the ceiling surface in order to reduce the height of the detachable hood 100. The centrifugal fan 200 includes an impeller housing 210 in which the impeller 240 is accommodated, and a tubular impeller discharge portion extending in a tangential direction of the impeller 240 so that air sucked from the impeller 240 is discharged. 220). A flange 230 that can be inserted into the above-described centrifugal fan coupling unit 134 may be formed at an end of the impeller discharge unit 220 to extend outwardly of the impeller discharge unit 220.

The lower surfaces of the impeller housing 210 and the impeller discharge unit 220 are formed to have an opening, so that the opened lower end may be installed so as to contact the lower surface of the lower housing 112. Accordingly, a flow path may be formed in the centrifugal fan by the impeller housing 210 and the impeller discharge unit 220 and the lower housing 112. This structure helps to simplify the configuration required for the centrifugal fan 200, and further helps to reduce the vertical length of the kitchen detachable hood.

The impeller housing 210 includes a motor 250 is accommodated in the lower portion, and a motor installation member 251 for installing the motor 250. The impeller 240 is accommodated by the outer weight of the motor installation member 251 and a flow path through which air can flow in the radial direction of the impeller 240 is formed, and a hole is formed in the center so that air is sucked into the impeller 240. Can be formed. At this time, the motor installation member 251 may be fastened to the bolting portion 151 of the above-described installation panel 150 by a bolt or the like. Further, the motor 250 and the impeller 240 are connected by a motor shaft, and the motor shaft hole 270 through which the motor shaft and the motor shaft pass may be formed in a D shape as shown in FIG. 5. This is to prevent the impeller 240 from slipping from the motor shaft.

In addition, the overall height of the impeller housing 210 may be formed smaller than the height of the suction pipe 121. This is shown in FIG. 6 and is for applying a centrifugal fan instead of an axial fan to the hood, and is a structure in which the direction of the suction port 123 and the discharge port 133 is not vertical and is formed in one (一) shape. . Therefore, since the height of the impeller housing 210 is formed lower than the height of the housing 110 and the suction port 123, it is possible to install the detachable hood 100 to which the centrifugal fan 200 is applied between the suction straight kitchen ventilation ducts.

Moreover, as shown in Figs. 4 and 6, it is preferable that the height of the upper surface 210b on the side of the discharge unit 130 is higher than the upper surface 210a on the side of the suction unit 120 of the impeller housing 210 . To this end, as shown in FIG. 6, a downward slope toward the suction part 120 is formed on the suction part 120 side of the impeller housing 110 (the first slope (A)), and the impeller 240 and the housing ( An upward inclination toward the discharge part 130 may be formed at a portion extending from the suction part 120 side to the discharge part 130 side of 110) (the second inclined part (B)). In other words, the second inclined portion (B) is formed in a portion extending from the suction portion 120 side to the discharge portion 130 side of the impeller housing 210, the flow path formed by the impeller housing 210 gradually upward. It can be formed in the form of expanding.

The inclination formed on the second inclined portion (B) is, in particular, taking into account that the air flows from the impeller 240 and the air is stacked in the impeller 240 and the housing 110, and is directed toward the impeller discharge portion 220 for smooth ventilation. It is a structure that can contribute to forming a larger flow path. Furthermore, since the air flowing into the suction unit 120 due to the second slope B is blocked by the height of the suction unit 120 and the discharge unit 130, the impeller 240 does not advance toward the discharge unit 130. ) Can have a structure that can be introduced.

In addition, the first inclined portion (A) may be formed inclined downwardly inclined from the upper end of the suction portion 120 side of the impeller housing 210. Therefore, as a result, it may be seen that the flow path of the corresponding part is reduced, but this part is a corner space that is hardly utilized for air flow, so that the dead space can be utilized and air can be smoothly introduced into the impeller 240 side. I did it.

The impeller discharge unit 220 is a tubular shape connected from one side of the impeller housing 210, and the air flowing from the impeller housing 210 along the radial direction of the impeller 240 along the flow direction of the air is the impeller 240 It is extended so that it can be discharged in the tangential direction of.

The impeller discharge unit 220 is positioned at the outer portion of the flow path of the centrifugal fan 200 based on the central portion of the impeller 240 and extends in the tangential direction of the impeller housing 210 and the first surface 220a It may include a second surface 220b extending from a side facing the first surface 220a. Accordingly, a corner 221 where the second surface 220b and the impeller housing 210 meet is formed.

The centrifugal fan 200 of the present invention may have a convex surface 222 protruding outside the flow path on the second surface 220b based on the corner 221. It is preferable that the convex surface 222 is formed in a curved shape that gently protrudes as shown in FIG. 7. This convex surface 222 is different from the extension direction of the first surface 220a and the extension direction of the discharge port 133, so that air cannot exit the discharge port 133 and returns to the impeller 240 side or the second surface 220b ) It is to prevent congestion in the vicinity. That is, air is collected on the convex surface 222 and can be smoothly discharged to the discharge port 133.

In addition, the centrifugal fan 200 of the present invention may further include a noise reflecting part 223 extending from the edge 221 to the inside of the impeller discharge part 220 by a predetermined length. The noise reflecting unit 223 is a structure for reflecting noise radiated from the discharge unit 130 to the suction unit 120 without interfering with the flow of air. Further, it is preferable in terms of air flow and noise that the noise reflecting unit 223 is formed as a curved surface formed so that the slope from the convex surface 222 changes continuously, and the end of the noise reflecting unit 223 is the suction port 123 It is preferably formed to face.

By the structure of the present invention detachable hood 100 described above, the hood is not located on the top of the crater and is moved to the inside of the ceiling, so that the noise in the kitchen due to the operation of the hood can be drastically reduced. In addition, through the structure of the housing 110 and the impeller housing 210, there is an effect that the centrifugal fan 200, which is about 30% more efficient than the axial fan, can be applied to a narrow ceiling space.

In addition, the convex surface 222 of the impeller housing 210 and the noise reflecting unit 223 improve ventilation efficiency and at the same time reduce the noise radiated toward the suction port 123.

On the other hand, for convenience, the impeller housing 210 is installed on the lower surface of the lower housing 112 in the specification and drawings, and a gap is formed between the impeller housing 210 and the upper housing 111, so that air is placed in the upper part of the impeller housing 210. Although described and illustrated as being introduced into, it can be said that it belongs to the scope of the present invention as long as it conforms to the essence of the present invention even if the upper and lower sides are changed.

In the present specification, each of the embodiments has been described separately, but embodiments that can be derived by combining each of the embodiments are also within the scope of the present invention.

The above description is merely illustrative of the technical idea of the present invention, and those of ordinary skill in the art to which the present invention pertains are capable of various modifications and variations without departing from the essential characteristics of the present invention.
