Description

Hood for roaster {DUCT FOR ROASTER}

The present invention relates to a hood for the roaster, and more particularly to the exhaust duct of the hood for the roaster in the form of telescopic pipe (Telescopic Pipe) to be able to extend and shorten in the axial direction.

In general, a smoke discharger is used to discharge smoke or odor generated when grilling meat or fish in a restaurant to the outside. For example, a ventilator is installed on a wall to use the entire space. And there is a limit to the discharge of oil, etc., in particular, there is a problem in that the ventilator must be operated in unison regardless of whether the meat is grilled in one place or grilled in several places.

Accordingly, in recent restaurants, a hood for a roaster for locally discharging smoke is used only at a place where meat is grilled, and the hood for the roaster is provided to exhaust smoke or odor from various restaurants or kitchens. It is a kind of processing device, mainly composed of a hood fan rotated by an electric motor and an exhaust duct of a tubular shape having a certain length, and is made in various forms according to the installation place and purpose to be used.

On the other hand, recently used hood duct structure is largely made of a cylindrical tube or a corrugated pipe shape having flexibility, the latter bellows type bellows type duct structure is a duct having a constant length in the lower portion of the hood fan is connected in communication. It is made in the form of a corrugated pipe made of a material having nonflammability and flexibility.

However, the conventional duct of the hood is flexible and made of a corrugated pipe shape, although the length can be adjusted in a relatively free position movement and foldable form, but the appearance is not strong, so breakage is easily caused by a small impact, thereby providing a normal exhaust. There is a problem of not performing a function.

In addition, the conventional duct takes the state that the corrugated pipe is folded to adjust the length, the condensation phenomenon is generated by the oil mixed in the smoke during the discharge of smoke and odor, water is accumulated in the folded portion, When the length of the duct is adjusted, the water drops down to where cooking is being done, and contaminates food.

The present invention is to solve this problem, the object of the present invention is to provide a hood for the roster having a semi-permanent durability while freely elongating and shortening in the axial direction.

The present invention for achieving the above object, a plurality of exhaust pipe is elastically coupled in multiple stages, the upper end of the upper exhaust pipe is coupled to the coupling, the lower end of each exhaust pipe except the upper exhaust pipe, the separation prevention jaw is It is formed, and the engaging jaw is bent at the upper inner circumference of the lower exhaust pipe into which the respective exhaust pipe is inserted.

Hereinafter, the hood for the roaster according to the present invention will be described according to the embodiment shown in the accompanying drawings.

As illustrated in FIG. 1, the roster hood of the present invention includes a blower main body 10, an exhaust duct coupled to a lower portion of the blower main body 10, and a connection pipe 50 connecting the blower main body and the exhaust duct. And a suction pipe 80 coupled to a lower portion of the exhaust duct and configured to have a fallopian tube shape to suck smoke.

The blower main body 10 is coupled to the bottom of the ceiling, and there is an impeller and an intake motor for suctioning and discharging smoke generated during cooking, although not shown therein.

The exhaust duct, as shown in Figures 1 to 3, the first exhaust pipe 20, the second exhaust pipe 30 and the third exhaust pipe 40 is formed in multiple stages in the form of telescope, the diameter of the lower end It gradually increases toward the exhaust pipe. That is, the diameter of each exhaust pipe becomes larger from the first exhaust pipe 20 to the third exhaust pipe 40. (In this design, an exhaust duct consisting of three stages will be described as an example.)

At this time, the upper outer periphery of the second exhaust pipe 30 and the third exhaust pipe 40, each of the exhaust pipe in the axial direction when the expansion and contraction while holding the center of the exhaust pipe and the snap ring (32) (42) so that the exhaust pipe does not escape ) Are respectively combined.

And, as shown in Figure 3, at the lower end of the first exhaust pipe 20 and the lower end of the second exhaust pipe 30, the departure prevention jaw (20a) (30a) is formed to be curved outwardly, the second exhaust pipe ( 30) and the upper end of the third exhaust pipe 40 is engaged with the separation prevention jaw (20a) (30a) is formed to be integrally bent to the locking jaw (30b) 40b inward so that each exhaust pipe is not separated.

On the other hand, when the exhaust pipe 20, 30, 40 for releasing the smoke generated during cooking of the food in the axial direction, the diameter difference between the exhaust pipe 20, 30, 40 at the completion of the expansion Due to the possibility that the exhaust pipe 20, 30, 40 flows, in order to prevent this, as shown in Figure 2, the lower outer peripheral surface of the first exhaust pipe 20 and the second exhaust pipe 30 flow prevention ring (21) and (31) are combined.

The flow preventing rings 21 and 31 eliminate the diameter difference between the upper exhaust pipe and the lower exhaust pipe, that is, the lower end of the first exhaust pipe 20 and the upper end of the second exhaust pipe 30 and the second exhaust pipe 30 when the exhaust duct is extended. By reducing the diameter difference between the lower end of the exhaust pipe 30 and the upper end of the third exhaust pipe 40 to minimize the flow of each exhaust pipe.

In addition, the upper side of the first exhaust pipe 20, the connecting pipe 50 is coupled to connect the first exhaust pipe 20 to the blowing main body 10, the connecting pipe 50 is the first exhaust pipe 20 It is fixed to one or more rivets (70). Accordingly, the head of the rivet 70 protrudes outward of the first exhaust pipe 20, and the snap ring 32 coupled to the upper end of the second exhaust pipe 30 contacts the rivet head when the exhaust duct is shortened. When the exhaust duct is shortened, the snap ring 32 in contact with the rivet head may be damaged by the local pressure.

Therefore, in the present invention, a substantially cylindrical reinforcement member 60 having an upper surface and a lower surface open to the outer side of the connection pipe 50 is provided, and the reinforcement member 60 is curved outward at the top of the connection pipe 50. The lifting operation is controlled to be controlled by the support jaw 51 that is formed so as not to be separated from the connecting pipe 51.

In addition, since the support part 61 is bent inwardly on the lower surface of the reinforcing member 60, the snap ring 32 is damaged since the contact portion 61 is generally brought into contact with the snap ring 32 of the second exhaust pipe 30 when the exhaust duct is shortened. Can be minimized.

On the other hand, the expansion and contraction operation for the exhaust duct consisting of a multi-stage is controlled by an operation switch 11 connected to one side of the blower main body 10, the wire rope is connected to the operation switch (not shown), the wire rope The end of is wound around a pulley provided so as to be capable of forward and reverse rotation by a drive motor inside the blower main body 10 while being connected to the lower end exhaust pipe.

Referring to the operation of the hood for a roster configured as described above is as follows.

When the impeller is operated while the exhaust duct is extended and lowered, a strong suction force is generated inside, and smoke and odor generated when cooking food in the room are introduced through the suction pipe 50 and guided through the exhaust duct.

When the cooking of the food is completed, the exhaust duct is raised and stored, and the raising and lowering operation is performed by the user by controlling the operation switch 11.

That is, when the driving motor is operated by the application of the control signal, the pulley subjected to the rotational force rotates in the forward direction, and as a result, the wire rope is wound so that the third exhaust pipe 40 having the tip connected to the rope hanger is gradually raised. .

As a result, the second exhaust pipe 30 is sequentially raised to the first exhaust pipe 20 to finally achieve a non-use state. The up and down movement of the exhaust pipe is automatically performed by the winding or unwinding of the wire rope. Can be done.

On the other hand, in the present invention has been described an exhaust duct structure consisting of three stages as an example, it is apparent that the exhaust duct structure of the present invention can be variously modified by those skilled in the art.

For example, the exhaust pipe can be changed into two or more stages or multiple stages according to the indoor ceiling height.

As described above, according to the present invention, the exhaust duct is manufactured in a telescope type, but the separation prevention jaw and the locking jaw are integrally manufactured so as not to be separated by being engaged with the lower and upper ends of each exhaust pipe, thereby simplifying the manufacturing process. It is possible to reduce, by minimizing the breakage of the snap ring coupled to the outer peripheral edge of the lower exhaust pipe by combining the reinforcing member on the outer side of the lower exhaust pipe.
