Description

A roaster in which the oil filter unit is coupled to the inner bottom of the roaster {Roaster with easy to clean and changing oil filter}

The present invention relates to a roaster, and more specifically, to a roaster in which an oil filter unit, which filters oil from smoke exhausted from a roaster for grilling meat, is coupled to the inner bottom of the roaster.

Typically, a roaster is installed in the center of the table in a restaurant so that meat can be grilled directly using charcoal, gas, electricity, or a heat radiator.

In particular, electric roasters are widely used because they are convenient and simple to use. In these electric roasters, the high-temperature heat generated from the electric heater, which is the heat source, is not transmitted to the body of the roaster, solving the problem of the body of the roaster being heated to a high temperature. I'm doing it.

However, most roasters 10 generate odors and smoke when grilling meat, which remains in the surrounding space and irritates the user's nose and eyes. To this end, smoke is placed at the top or bottom of the roaster 10. A duct may be installed for forced suction.

In addition, a separate filter 20 may be provided to filter out fine oil particles contained in the smoke when the smoke is discharged. As shown in FIG. 1, the conventional roaster 10 has a filter 20 located at the center of the roaster 10. A burner stand (40) is installed across the , and a burner (41) and a charcoal container are combined on it.

However, since the conventional roaster 10 does not have much space between the inner walls of the roaster 10, the filter 20 cannot be installed by inserting it into the bottom side of the roaster 10. Therefore, the filter 20 is separately installed on the lower side of the table 30 to filter oil from the smoke and discharge it toward the exhaust pipe 11.

That is, a separate hood box 31 is provided at the bottom of the table 30, the filter box 21 is installed here, and then the filter 20 is inserted inward from the side of the filter box 21 and joined. .

Therefore, the conventional roaster 10 has a problem in that the configuration becomes complicated and the size of the equipment increases, and the filter 20 must be cleaned separately from cleaning the inside of the roaster 10, so it takes a lot of cleaning time. Therefore, there is a disadvantage of increased manpower consumption.

In addition, in order to clean the filter 20, the operator must bend his/her waist, open the filter door 22 provided on the side of the filter box 21, and remove the filter 20 from the filter box 21. So it was very uncomfortable. In addition, the worker had to bend his or her waist to insert the cleaned filter 20 into the filter box 21, making the work difficult.

Accordingly, there are frequent cases where workers do not regularly clean the filter 20 and neglect it, which results in oil accumulating in the filter 20 and, in some cases, fires.

Of course, it would be natural that one of the first, second, third, and fourth filter bands 310, 320, 330, and 340 could be removed or combined in plural depending on the situation.

The oil filter unit 300, in which the first, second, third, and fourth filter bands 310, 320, 330, and 340 are stacked and combined, is inserted through the upper part of the roaster 100, which in turn is inserted into the movable ring ( 150) and the roaster 100 are inserted into the inner bottom through the space between the sides and coupled thereto.

In addition, the inserted oil filter unit 300 is firmly coupled to the exhaust pipe 200 provided on the inner bottom surface of the roaster 100, so that oil is filtered from the smoke flowing into the roaster 100 and then the smoke is discharged into the exhaust pipe 200. ) is discharged to the side.

After the oil filter unit 300 is coupled, the force is removed from the moving ring 150 that was applying the force. Accordingly, as the sliding shaft 162 is pushed to its original position by the elastic force of the compressed elastic spring 124, the moving table 161 also moves to its original position, and at the same time, the moving ring 150 is also moved from the upper part of the fixed ring 140. It moves to the original position.

Accordingly, foreign substances such as pieces of meat generated during grilling of meat are collected by the concave groove 311 of the first filter 310, and smoke is sucked in by the suction force of the exhaust pipe 200 to the inside of the roaster 100. It is discharged to the exhaust pipe 200 through.

At this time, as the smoke inside the roaster 100 passes through the oil filter unit 300, the oil contained in the smoke is filtered and then discharged.

And, the smoke is absorbed by the oil collecting part 322 of the second filter unit 320, the oil collecting part 332 of the third filter unit 330, and the oil collecting part 342 of the fourth filter unit 340. The contained oil is filtered out. And, the oil-covered smoke is again discharged through the smoke distribution hole 335 formed in the upper wall 337 of the third filter unit 320, and the upper wall 347 and lower wall 348 of the fourth filter unit 340. It flows into the central through-holes 321, 331, and 341 through the smoke distribution hole 345 formed in and is discharged through the exhaust pipe 200 at the bottom.

Accordingly, the smoke generated by combustion while grilling meat passes through the oil filter unit 300 and is discharged after the oil contained in the smoke is filtered.

Also, in order to clean the oil filter unit 300, when the oil filter unit 300 is pulled out, the process is carried out in the same manner as when the oil filter unit 300 is inserted.

Therefore, the oil filter unit 300 of the present invention is installed on the inner bottom side of the roaster 100, so there is no need to provide a separate space to install the oil filter unit 300, which can reduce the size of the product. There is an effect.
