A groove-shaped oil pan 3 is provided along the four circumferences of the lower edge of the inner surface of the hood 1, the lower edges of a pair of grease filters 4 are inserted into both oil pans 3, and the upper edge of the grease filter 4 is connected to the hood 1. The grease filters 4 are arranged in an inclined manner so as to approach each other at the upper center of the hood 1, and a roughly inverted V-shaped oil and fat collecting plate 5 is attached to the hood 1 so as to straddle the upper ends of both grease filters 4. A grease filter 4 is attached to a hanging fitting 36 provided at the lower end of the oil and fat collection plate 5, which is provided on the inner upper part and has an approximately inverted V-shaped cross section.
The grease filter device is characterized in that a small gap 50 is formed between the upper end of the back surface of the grease filter 4 and an opposing oil/fat collecting plate 5.

Conventionally, as shown in FIG. 1, a groove-shaped oil pan 3/ with a flat bottom surface is provided along the center of the lower part of the hood 1, and partition plates are provided at the top of both sides of the hood 1'. 6'
A pair of grease filters 4/ are installed in an inverted V-shape between the oil pan 3/ in the center and the oil pan 3/.
The fats and oils collected in the collector cup 7/(,1) were stored in the hood 1'.

Since the grease filter 4' is arranged in this way, the hood 1 is placed on the lower surface side of the grease filter 4'.
The problem is that the inner wall surfaces A I on both sides of the hood 1' are exposed, and raw oil smoke that has not been degreased adheres to the exposed inner wall surfaces A I on both sides of the hood 1', making them dirty, unhygienic, and easily flammable. was there.

In addition, oil smoke from before degreasing may adhere to the bottom surface of the oil pan 3'.
The oil in the oil pan 3' is condensed and drips into the cooking device 8', easily igniting, and is unsanitary.Moreover, the oil pan 3' is located directly above the cooking device 8' or near the flame, and the oil in the oil pan 3' There was a problem that it became warm and high and could easily catch fire.

The present invention has been made in view of the drawbacks of the conventional example described above, and its purpose is to prevent oil smoke before degreasing from hitting the inner wall tubes on both sides of the hood, so that fats and oils do not adhere to the cooking utensils. To provide a grease filter device in which oil does not drip onto a flame and the temperature of the oil in an oil pan is not easily raised by the flame.

The present invention will be explained in detail below with reference to the accompanying drawings.

What is shown in FIG. 2 is an outline of the present invention.

Reference numeral 1 denotes a substantially box-shaped hood with an opening at the bottom, and a large duct opening 2 is previously opened on the top surface of the hood 1, and a groove-shaped oil pan 3 is provided along the lower edge of the inner surface of the hood 1.
has been established.

An oil and fat collection plate 5 having a substantially inverted V-shaped cross section is attached to the upper center of the hood 1, and fire prevention dampers 9 are provided on both sides of the oil and fat collection plate 50, which also serves as air volume adjustment.

The upper edges of the pair of grease filters 4 are arranged to be inclined in a substantially V-shape so that they are close to each other under the oil collecting plate 5.

Therefore, oil smoke rising from the cooking device 8 etc. passes through the grease filter 4 to collect oil and fat, and the degreased smoke (hot air) passes through the hood 1 and is exhausted from the duct opening 2. The hood 1 is kept clean, with only degreased hot air blowing against both inner walls of the hood 1 and no fats or oils adhering thereto.

The fats and oils adhering to the bottom surface of the fats and oils collection plate 5 flow along the slope of the fats and oils collection plate 5 to the back side of the grease filter 4, and further flow along the back side of the grease filter 4 and are collected in the oil pan 3, where the fats and oils are collected. No oil or fat drips from the collection plate 5 into the cooking device 8 or the flame below, which is safe and good for hygiene.

In addition, the oil and fat collected in the oil pan 3 is removed from the oil drain pipe 10.
The water is collected in the collector cup 7 outside the hood 1.

Therefore, the oil pan 3 and the collector cup 7 are located away from the cooking device 8 and the flame, and there is very little risk that the oil mixture therein will rise and cause a fire.

Further, the fire damper 9 adjusts the air volume by adjusting the degree of opening of its ventilation opening 11. Furthermore, in the event of a fire, the fire damper 9 can be closed to prevent fire from entering the duct 12. .

The duct 12 is formed separately from the hood 1 and is assembled over the duct opening 2.

．． Further, detailed embodiments of the present invention will be explained with reference to FIGS. 3 to 25.

The oil and fat collecting plate 5 is bent to have a substantially inverted V-shaped cross section.
The partition plate 6 of the fire damper 9, which is provided with ventilation openings 11, extends diagonally outward and upward from both lower side edges of the oil and fat collection plate 5, and the entire body is separated from the oil and fat collection plate 5 and the partition plate 6K. It has a substantially W-shaped cross section, and a chamber part 14 is formed by fixing horizontal plates 13 to both sides of the lower part of the oil and fat collecting plate 5.

Furthermore, trapezoidal panels 15 are screwed to both ends of the ninth panel.
A filter top 16 as shown in the figure is constructed.

The hood 1 is not a one-piece unit but an assembly type, and includes a pair of side plates 17 (Fig. 7) and a pair of aprons 18 (Fig. 8).
and a top plate 19 (Fig. 21 or 23), and the hood 1 can be transported to the site and assembled on site, making it easy to transport the hood 1 without adding bulk. Easy to transport.

As shown in FIG. 10, the filter top 16 is secured with screws so as to span between the upper parts of the pair of side plates 17.

Further, an apron 18 is attached to the front and rear of the filter top 16, and a top plate 19 is attached to the upper surface.

As shown in FIGS. 4 and 5, the filter top 16
A pivot shaft 20 that can freely rotate is horizontally suspended between the side plates 17 on both sides of the fire damper 9 , and the hinge portion 22 of the fire damper 9 that closes the ventilation opening 11 is integrally inserted into the pivot shaft 20 . The fire damper 9 is configured to rotate together with the rotation shaft 20, and the fire damper 9 is elastically biased in the closing direction by a spring 23.

Reference numeral 24 denotes an opening holding device for holding the Boei damper 9 at an appropriate opening angle.

That is, a bimetal plate has a latch gear 21 rotatably fitted around a rotation shaft 20, rotation of the latch gear 210 is prevented by a rotation stopper 25 fixed to a partition plate 6, and a base fixed to a fire damper 9. A cut and raised piece 27 is made to protrude from the tip of 26 toward the high expansion side, and the cut and raised piece 27 is engaged with the rasochi gear 21, and the pusher is slidably inserted into the apron 18 as shown in FIG. The tip of the rod 28 is opposed to the high-expansion side surface of the tip of the metal plate 26, and the push rod 28 is biased to protrude toward the outside of the hood 1 by a spring 29K.

Due to the engagement between the latch gear 21 and the cut and raised piece 27, the fire prevention damper 9 can be rotated in the α direction in FIG. 6 without clicking, but the latch gear 21 and the cut and raised piece 27 can be rotated in the β direction in the figure. It cannot be rotated unless the mesh is released.

By turning the hand/I/30 provided at the end of the rotating shaft 20 outside the side plate 17, the fire damper 9 can be opened by a free angle and the amount of ventilation of the ventilation opening 11 can be adjusted. When the inside of the hood 1 becomes abnormally humid due to a fire outbreak, etc., the pi-metal plate 26 curves toward the low expansion side, and its cut and raised piece 27 comes off from the latch gear 21, and the elastic force of the spring 230 causes the fire damper to move. 9 is forcibly closed to prevent the spread of fire.

To manually close the fire damper 9, push the push rod 28. As shown in FIG. The fire damper 9 is closed.

The one shown in FIG. 19 atbK is another example of the open holding device 24, which is a manual type, in which a latch gear 21 is integrally fitted onto a rotation shaft 20 outside the side plate 17.
A rotatable locking pawl 31 provided below the locking pawl 31 is engaged with the latch gear 21 by the elastic force of a coil spring 320, and when the string 33 tied to the locking pawl 31 is pulled downward, the locking pawl 31
is disengaged from the latch gear 21, and the fire damper 9 is closed by the spring 23K.

45 is a hook hole into which one end of the coil spring 32 is fitted.

34 is a heat exchange pipe disposed below the partition plate 6 in the hood 1, a part of which is piped inside the chamber part 14, and the end of the heat exchange pipe 34 is placed outside the side plate 17. It's being pulled out.

The heat exchange pipe 34 may have a shape as shown in FIG. 13aK, or may have a shape as shown in FIG. 13b.

The grease filter 4 is made up of two rows of reversely facing buffs/435, as shown in FIG. As the oil passes in a meandering manner, the flow velocity is increased and the direction is forcibly changed.As a result, the oil and fat in the oil smoke collides with the baffle plate 35K, and the oil and fat in the oil smoke is separated and collected.

On the inner surface of the lower edge of the hood 1, an oil pan 3 having a square annular groove is provided below the filter top 16 as shown in FIG.
The upper end of the grease filter 4 is hung on a hanging fitting 36 provided at the lower end of the oil collecting plate 5 as shown in FIG. Place the lower end of the grease filter 4 on the metal fitting 3γ and
As shown in FIG. 4, a pair of grease filters 4 are removably mounted inside the hood 1 so as to face each other in a substantially V-shape.

When the upper end of the grease filter 4 is hooked on the hanging fitting 36, a small gap 50 is formed between the upper end of the back surface of the grease filter 4 and the opposing oil/fat collecting plate 5, as shown in FIG. It looks like this.

An inspection port 39 with a door 38 is opened in the apron 18, and the fire damper 9 inside the hood 1 and the back side of the grease filter 4 can be inspected through the inspection port 39.

As shown in FIG. 21, the top plate 19 has a large duct opening 2, and a stepped plate 40 is welded in a U-shape to the top surface of the top plate 19 along the edge of the duct opening 2. An adjustment groove 41 is formed on the edge of the duct opening 2 by pasting and attaching the adjustment groove 41 using a method such as the following.

Reference numeral 12 in FIG. 20 is a single type duct, and a flange 42 extends outward from the lower edge of the duct 12.

Then, while snoding, the flange 42 of the duct 12 is fitted into the adjustment groove 41 on the edge of the duct opening 2, and then the stepped plate material 40 is placed on the remaining edge as shown in FIG.
The duct 12 is attached to the top plate 19 by fitting the duct 12 into the adjustment groove 41, and the position of the duct 12 can be adjusted by adjusting the depth of fitting of the flange 42 of the duct 12 into the adjustment groove 41.

12 shown in Fig. 23 is a double type duct;
A connecting member in which a flange 42 extends outward from the three sides of the lower end of each duct 12, and a notch 43 is provided by slightly notching the remaining side, and both ends are bent upward as shown in FIG. As shown in FIG. 24, the two ducts 12 are arranged in the duct opening 2 while being connected to each other via the duct 44 so that no gap is created between them, and the positions of the two ducts 12 can be adjusted separately.

As described above, the present invention has an opening in the upper part of the hood which is open at the bottom, groove-shaped oil pans are provided along both lower edges of the inner surface of the hood, and the lower edges of a pair of grease filters are inserted into both oil pans. The grease filter is arranged in an inclined manner so that the upper edge of the grease filter approaches the upper center of the inside of the hood, and a roughly V-shaped grease trap is installed so that it straddles the upper ends of both grease filters. Since the collecting board is installed at the top inside the hood, the inner walls on both sides of the hood are blocked by the grease filter and are not exposed, and even though the hot air that has been degreased by the grease filter hits it, the raw oil smoke that has not been degreased hits it. The inner surfaces of both sides of the hood are clean and free of oil and fat.
It has the advantage that there is no risk of burning.

In addition, the upper end of the grease filter is hung on the hanging fitting provided at the lower end of the grease collecting plate, which has a roughly ■-shaped cross section, and a small gap is formed between the upper end of the back surface of the grease filter and the opposing grease collecting plate. Therefore, not only can the oil and fat collection plate be removably attached using a simple method of hooking the upper end of the grease filter, but also the oil and fat adhering to the bottom surface of the oil and fat collection plate can be removed from the slope of the oil and fat collection plate. Along the line, the grease falls through the small gap between the grease collecting plate and the upper end of the back of the grease filter to the back of the grease filter, and is collected in the oil pan along the back of the grease filter. This prevents fats and oils from condensing at the lower end of the collector plate and dripping into the cooking device or flame below.

Moreover, since the oil pan is installed on both sides of the hood, it is away from the cooker or the flame and the temperature of the oil in the oil pan becomes high. Therefore, there is no risk of fire.
It has the advantage of being clean.
