Description

The present invention relates to a smoke purifying device.

In restaurants, large amounts of oily smoke can be generated when cooking using cooking equipment. If the oily smoke cannot be captured by the exhaust system installed in the restaurant's kitchen, it can reach the dining area and cause discomfort to customers.

In this regard, for example, Patent Document 1 below discloses the use of an air purifier to purify the air.

JP 2002-364891 A

However, in the exhaust devices disclosed in the above-mentioned prior art documents, the filters become clogged in a short period of time, making it difficult to purify oil smoke over a long period of time.

In addition, the exhaust devices disclosed in the above-mentioned prior art documents exhaust air from above the device, so if they are used in a smoke purifying device, the smoke may spread over a wide area, causing discomfort to customers.

The present invention was invented to solve the above problems, and aims to provide an oil smoke cleaning device that can purify oil smoke on restaurant floors for a long period of time and prevent the oil smoke from spreading over a wide area.

The oil smoke purifying device according to the present invention for achieving the above object is an oil smoke purifying device arranged on the floor of a restaurant. The oil smoke purifying device includes a housing having an intake port at an upper part for taking in exhaust air flowing from a kitchen of the restaurant onto the floor and an exhaust port at a lower part for discharging air only toward the floor surface , a blower arranged within the housing, an exhaust passage through which the airflow generated by the blower passes, a disk-shaped oil collection filter arranged upstream of the blower and having holes, a motor to which the oil collection filter is detachably attached and which rotates the oil collection filter at high speed, and an air purification filter arranged downstream of the blower and functioning as a deceleration mechanism for decelerating the airflow generated by the blower.

According to the oil smoke purification device configured as described above, the oil collection filter rotates at high speed using a motor, making it possible to effectively collect oil from the exhaust air that flows from the restaurant kitchen onto the floor and from the exhaust air generated by cooking at customer tables. Because the oil collection filter is not easily clogged, it can effectively collect oil smoke on the restaurant floor for a long period of time. In addition, because exhaust is performed from below the device, it is possible to prevent the oil smoke from spreading over a wide area. From the above, it is possible to provide an oil smoke purification device that can purify oil smoke on the restaurant floor for a long period of time and prevent the oil smoke from spreading over a wide area.

In the following description, the left-right direction when viewed from the front side is referred to as the X direction, the depth direction of the oil smoke purification device 1 is referred to as the Y direction, and the vertical direction is referred to as the Z direction (see Figure 1).

The oil smoke purification device 1 according to this embodiment is placed on the floor of a restaurant. Here, the floor of a restaurant refers to the space excluding the kitchen, including seating areas, stairs, entrances, etc.

As shown in Figs. 1 to 14, the oil smoke purification device 1 according to this embodiment has a housing 10 provided with an intake port (gaps 20A, 20D, 20E) for taking in air and an exhaust port 16C for discharging air, a straightening plate 20 provided on the side and top of the housing 10, a blower 30 arranged inside the housing 10, an exhaust passage 40 through which the airflow generated by the blower 30 passes, an oil collection filter 50 arranged upstream of the blower 30, a motor 60 for rotating the oil collection filter 50 at high speed, an oil recovery section 70 for recovering oil collected by the oil collection filter 50, and an air purification filter (corresponding to a sound absorbing mechanism and a reduction mechanism) 80 arranged downstream of the blower 30. Each component will be described below.

<Housing 10>
As shown in Figures 1 to 5 and 8, the housing 10 has a front panel (equivalent to a decorative panel) 11 provided on the front side, a right side panel 12 provided on the right side when viewed from the front side, a left side panel 13 provided on the left side when viewed from the front side, a rear panel 14 provided on the rear side, a mounting portion 15 provided on the top surface, a bottom portion 16 provided on the bottom surface, a panel inclined portion 17 provided on the positive side of the front panel 11 in the Y direction, and an inner panel 18 provided inside the front panel 11, the right side panel 12, the left side panel 13, the rear panel 14, and the bottom portion 16.

As shown in FIG. 6, the front panel 11 is provided at a position corresponding to the blower 30 in the Z direction. By positioning the front panel 11 in this way, the front panel 11 functions as a soundproofing panel to reduce the sound of the fan motor 32 of the blower 30 that is transmitted to the audience seats.

As shown in Figures 1 and 3, the front panel 11 is configured to be lower in the Z direction than the right side panel 12 and the left side panel 13. A straightening plate 20 is disposed above the front panel 11 and between the right side panel 12 and the left side panel 13.

Slits 11A are formed along the Z direction between the front panel 11 and the right side panel 12, and between the front panel 11 and the left side panel 13.

The slit portion 11A is configured to be continuous in the Z direction with the gap 20A formed along the Z direction between the straightening plate 20 and the right side panel 12 and between the straightening plate 20 and the left side panel 13. With this configuration, the gap 20A and the slit portion 11A can be cleaned continuously, making cleaning easy. In addition, the uniformity of the design improves the design of the entire housing 10.

For example, if the slit portion 11A is not formed, the oil that falls through the gap 20A will spill out to the front side, which looks bad. In contrast, according to the oil smoke purification device 1 of this embodiment, the slit portion 11A is formed, so that the oil that falls through the gap 20A falls downward in the Z direction through the slit portion 11A without spilling out to the front side. This makes it possible to prevent the appearance from becoming bad.

2, between the top surface of the rectifying plate 20 and the housing 10, there is a gap 20D provided along the Y direction, and a gap 20E provided along the X direction. Gap 20D is formed along the Y direction from the negative end face to the positive end face in the Y direction of the rectifying plate 20, and slit portions 14B are formed on both sides of the mounting portion 15, continuing from this gap 20D. Gap 20E is a gap provided along the X direction, and is formed between the positive end in the Y direction of the top surface of the rectifying plate 20 and the mounting portion 15.

Gaps 20A, 20D, and 20E function as suction ports for taking in air. Here, the width of gaps 20A, 20D, and 20E is, for example, 10 mm to 20 mm. By forming the suction port with gaps 20A, 20D, and 20E in this way, the flow rate during suction can be increased, and oil smoke can be sucked in from a location that is a long distance away from gap 20A on the negative side of the Y direction. This makes it possible to more effectively purify the oil smoke. In addition, because the gaps 20A, 20D, and 20E that function as suction ports have a relatively small width, it is possible to prevent the sound of the motor 60 that rotates the oil collection filter 50 from leaking to the outside.

Gaps 20A, 20D, and 20E are set so that a person's fingers cannot reach all the way in. With this configuration, safety can be guaranteed because a person's fingers do not come into contact with the oil collection filter 50.

The gap 20A, which functions as a suction port, is formed in the Z direction from the upper end of the straightening plate 20 to the lower end of the straightening plate 20. With this configuration, the gap 20A is formed long in the Z direction, so that the oil smoke can be sucked in along the vertical direction (the direction in which the oil smoke falls). This improves the efficiency of suction of the oil smoke.

When the oil smoke purifying device 1 is placed in the seating area, it is preferable that the gap 20A is located at a position higher than the height of the seating area table (e.g., 70 cm). With this configuration, the oil smoke can be captured before it comes into contact with the table.

As shown in FIG. 1, the right side panel 12 is provided with a concave gripping portion 12A that is configured to be grippable. Similarly, the left side panel 13 is provided with a concave gripping portion (not shown) that is configured to be grippable.

As shown in FIG. 4, a power plug 14A is provided on the rear panel 14. As shown in FIG. 4, slits 14B are formed between the rear panel 14 and the right side panel 12, and between the rear panel 14 and the left side panel 13.

Electrical equipment (not shown) is placed on the placement section 15. As shown in Figs. 6 to 8, the placement section 15 is located higher than the lower end 20B of the straightening plate 20. With the oil smoke purification device 1 configured in this manner, if liquid (e.g. a drink) is spilled on the placement section 15, the liquid will fall along the arrow in Fig. 6, but because the electrical equipment is housed within the inner panel 18, it is possible to effectively prevent water from splashing on the electrical equipment. Similarly, if liquid is spilled on the top surface of the straightening plate 20, it is possible to effectively prevent water from splashing on the electrical equipment.

As shown in FIG. 9, the mounting section 15 can be opened and closed freely, and functions as a switch cover that covers the switch panel 15A. The switch panel 15A is a panel for instructing the operation of the oil smoke purification device 1, and is provided with, for example, an operation switch, an air volume switch, a timer switch, a lighting switch, etc.

As shown in FIG. 5, the lower surface portion 16 has a lower surface body 16A and a ventilation cover 16B. The ventilation cover 16B is fixed to the lower surface body 16A. The ventilation cover 16B is made of, for example, punching metal. As shown in FIG. 5, the ventilation cover 16B has a number of exhaust ports 16C for exhausting air. The exhaust ports 16C are formed to exhaust air toward the floor surface. With this configuration, air is exhausted toward the floor surface through the exhaust ports 16C, so that the diffusion of smoke can be suppressed and the exhausted air can be suppressed from hitting the customer and causing discomfort. In addition, since the exhaust ports 16C are provided on the lower surface portion 16 of the housing 10, the exhausted air can be suppressed from hitting the customer's feet, causing discomfort to the customer.

As shown in Figures 8 and 11, the panel inclined portion 17 is inclined so that it is on the upper side in the Z direction along the positive side of the Y direction. By providing the panel inclined portion 17 in this manner, the air entering through the gap 20A (especially the air entering from the lower region of the gap 20A) can be guided in the direction of the oil collection filter 50 (see the arrows in Figures 8 and 11).

As shown in FIG. 8, the inner panel 18 is configured in a hollow L-shape. Inside the inner panel 18, a blower 30, an air purification filter 80, etc. are provided.

Legs 90 are fixed to the bottom of the housing 10. The legs 90 are made up of four pieces. By providing the legs 90 on the bottom of the housing 10 in this way, it is possible to secure space between the floor surface and the bottom surface 16 of the housing 10, and air can be conveniently exhausted from the bottom surface 16. In addition, cleaning is easier because it is less likely to come into contact with the housing 10 when cleaning the floor surface.

<Current plate 20>
The straightening plate 20 is provided above the front panel 11 and between the right side panel 12 and the left side panel 13. As shown in FIG. 9, the straightening plate 20 is configured to be substantially L-shaped when viewed from the side. As shown in FIG. 9, the straightening plate 20 is rotatably attached to the inner panel 18. When the straightening plate 20 is closed, a gap 20A is formed as an intake between the straightening plate 20 and the right side panel 12 and between the straightening plate 20 and the left side panel 13. The straightening plate 20 is rotatable until it abuts against the placement portion 15. A gap 20C is formed between the straightening plate 20 and the front panel 11. The gap 20C functions as a clearance to prevent the straightening plate 20 from interfering with the front panel 11 when it is rotated.

As shown in FIG. 1, the air straightening plate 20 can be opened and closed by inserting a finger into the gap 20A serving as an intake port between the air straightening plate 20 and the right side panel 12, and between the air straightening plate 20 and the left side panel 13, and rotating the gap.

When the rectifier vane 20 is closed, it comes into contact with the proximity sensor S (see FIG. 9) located above the front panel 11. At this time, operation of the fan motor 32 and the motor 60 is permitted. On the other hand, when the rectifier vane 20 is opened, the rectifier vane 20 moves away from the proximity sensor S. At this time, operation of the fan motor 32 and the motor 60 is stopped.

As shown in Figures 6 to 8, the top surface of the air straightening plate 20 is arranged so that it intersects with the XY plane (horizontal plane) when the plate is closed. This configuration can prevent customers from placing cups or other objects on the air straightening plate 20.

<Blower 30>
As shown in Figures 6, 8, 10 and 11, the blower 30 is disposed inside the housing 10. The blower 30 has a fan 31, a fan motor 32, and a casing 33.

The blower 30 sucks in exhaust air containing oil smoke generated in the kitchen through the gaps 20A, 20D, and 20E, takes it in through the oil collection filter 50, and then discharges it from the exhaust port 16C on the underside 16 of the housing 10 (see the white arrow in Figure 6).

As shown in FIG. 6, the center of gravity G of the fan motor 32 is located below the center part P1 of the Z-direction height of the housing 10. With this configuration, the fan motor 32, which is a heavy object, is located below the center part P1 of the Z-direction height of the housing 10, so that the center of gravity of the oil smoke purification device 1 is stable and is less likely to tip over.

As shown in FIG. 6, the blower 30 is positioned so that the intake 30A of the blower 30 faces the rear side of the housing 10 (the positive side in the Y direction). With this configuration, the intake 30A of the blower 30 is blocked by the rear panel 14 of the housing 10. Therefore, the sound of the fan motor 32 is less likely to be transmitted from the intake 30A of the blower 30 to the seating area, improving the comfort of the seating area.

As shown in FIG. 8, the blower 30 is disposed below the gap 20A in the Z direction. As described above, the front panel 11 is disposed at a position corresponding to the blower 30 in the Z direction.

<Exhaust passage 40>
The exhaust passage 40 is passed through by the airflow generated by the blower 30. As shown in Fig. 6, the exhaust passage 40 has a first exhaust passage 41 provided below the oil collection filter 50 in the Z direction, and a second exhaust passage 42 provided between the outside of the blower 30 and the exhaust port 16C of the lower surface portion 16.

<Oil collection filter 50>
The oil collection filter 50 is provided above the blower 30, as shown in Fig. 6. The oil collection filter 50 is detachably attached to the shaft of a motor 60. The oil collection filter 50 collects oil from exhaust air containing oily smoke generated in a kitchen by a disk with holes rotating at high speed. The diameter of the holes provided in the oil collection filter 50 is, for example, 0.75 to 5 mm. The shape of the holes is not limited to a circle, and may be a triangle, a square, a regular polygon, or the like.

As shown in Figures 12 and 13, the oil collection filter 50 has a ventilation area 51 with holes and a peripheral portion 52 provided on the outer periphery of the ventilation area 51.

As shown in Figures 6 to 12, the ventilation area 51 is arranged perpendicular to the XY plane. In other words, the ventilation area 51 is arranged along the Z direction.

For example, if the oil collection filter 50 is positioned so that the ventilation area 51 is on the XY plane, the direction in which the droplets fall will coincide with the direction in which the holes in the ventilation area 51 penetrate, and the gravity of the droplets will all act in the direction in which the droplets pass through the holes. This makes it easier for the droplets to pass through the holes, so there is a risk that the droplets will get on the motor 60 if a drink is spilled from a cup.

In contrast, in the oil smoke purification device 1 according to this embodiment, the ventilation area 51 is arranged along the Z direction, so that the direction in which the droplets fall and the direction in which the holes in the ventilation area 51 penetrate are perpendicular to each other. This makes it possible to effectively prevent droplets from getting on the motor 60 even if a drink is spilled from a cup.

In this embodiment, the ventilation area 51 is arranged so as to be perpendicular to the XY plane, but the ventilation area 51 may be arranged so as to intersect with the XY plane. Furthermore, a configuration in which the ventilation area 51 is arranged along the XY plane is also included in the present invention.

As shown in FIG. 13, the peripheral portion 52 is bent relative to the ventilation area 51. Specifically, the peripheral portion 52 is bent toward the negative side of the Y direction relative to the ventilation area 51. By bending the peripheral portion 52 in this manner, the oil collected in the ventilation area 51 is caused by centrifugal force to fly toward the oil guard 71 provided on the negative side of the Y direction.

<Motor 60>
The motor 60 rotates at high speed the oil collection filter 50. The speed at which the motor 60 rotates the oil collection filter 50 at high speed is preferably, for example, 230 rpm (Rotation Per Minute) or more. As shown in FIG. 13 , the oil collection filter 50 is detachably attached to the motor 60 by a one-touch attachment/detachment mechanism 60A.

<Oil recovery section 70>
The oil collecting section 70 collects the oil collected by the oil collecting filter 50. The oil collecting section 70 has an oil guard 71, an oil panel 72, and an oil tray 73, as shown in Figures 12 and 13 .

As shown in FIG. 12, the oil guard 71 is disposed on the negative Y-side of the oil collection filter 50. As shown in FIG. 12, the oil guard 71 is disposed on the negative Y-side of the oil panel 72.

The oil guard 71 is integrated with the oil panel 72 to form an oil receiver 75 that receives the oil collected by the oil collection filter 50, and the oil received by the oil receiver 75 is transferred to the oil tray 73.

The oil guard 71 has a handle 71A attached to the top, and can be removed by grasping the handle 71A and pulling it from the negative side in the Y direction to the positive side in the Z direction.

With the oil recovery section 70 configured as described above, the oil collected by the oil collection filter 50 is blown to the oil guard 71 by centrifugal force and collected in the oil receiver 75 composed of the oil guard 71 and the oil panel 72. The oil collected in the oil receiver 75 is collected in the oil tray 73.

The oil recovery section 170 may be configured with an oil guard and an oil panel integrated together, as shown in FIG. 13. With the oil recovery section 170 configured in this manner, the oil collected by the oil collection filter 50 is blown by centrifugal force to the upstream wall section 171 of the oil recovery section 170, and is collected in the oil recovery section 170.

In the modified oil recovery section 170, the height of the downstream wall portion 172 of the oil recovery section 170 is set to be lower than the peripheral portion 52, as shown in FIG. 13.

For example, when the oil collection filter 50 is installed horizontally as shown in FIG. 14, the downstream wall portion 172 of the oil collection section 170 needs to be provided downstream of the oil collection filter 50 (below in the Z direction) in order to collect the oil collected by the oil collection filter 50. In this case, in order to remove the oil collection section 170, it is necessary to remove the oil collection filter 50 first, which is time-consuming. Furthermore, there is a risk that the inside of the housing 10 will become dirty due to oil dripping from the oil collection section 170, or due to oil remaining on the oil collection filter 50 dripping downward in the Z direction.

In contrast, according to the oil recovery section 170 described above, the height of the downstream wall portion 172 of the oil recovery section 170 is set to be lower than the peripheral portion 52, so that the oil recovery section 170 can be removed without removing the oil collection filter 50. This makes it easy to clean the oil recovery section 170. Furthermore, since the oil recovery section 170 is configured to prevent oil dripping, it is possible to suitably prevent the inside of the housing 10 from becoming dirty due to oil dripping from the oil recovery section 170.

Note that while FIG. 13 shows a case where the oil collection filter 50 is installed vertically, the angle of the oil collection filter 50 can be set as appropriate within a range in which oil dripping from the oil collection filter 50 does not escape from the oil recovery section 170. In addition, the height and position of the downstream wall section 172 of the oil recovery section 170 can be set at any position as appropriate, as long as it is lower than the peripheral section 52 and can recover dripping oil according to the installation angle of the oil collection filter 50.

<Air Purifying Filter 80>
The air purification filter 80 is provided downstream (downward in the Z direction) of the blower 30. The air purification filter 80 purifies the exhaust air sent from the blower 30. As shown in FIG. 6 , the air purification filter 80 has a smoke removal filter 81 and an odor removal filter 82.

The smoke removal filter 81 removes smoke by using a quasi-HEPA (High Efficiency Particulate Air) filter or the like.

The deodorizing filter 82 is installed downstream (below in the Z direction) of the smoke deodorizing filter 81. The deodorizing filter 82 contains activated carbon and the like, and as air passes through it absorbs odors contained in the air, separating and removing the odors from the air. The smoke deodorizing filter 81 and the deodorizing filter 82 are coated with a deodorizing agent that eliminates odorous components that have adhered to them.

The smoke removal filter 81 and the odor removal filter 82 are disposed inside the filter cover 83, as shown in FIG. 10. The air purification filter 80 can be accessed by removing the filter cover 83.

When replacing the air purification filter 80, remove the filter cover 83 and remove the smoke removal filter 81 or deodorization filter 82 from the replacement hole and replace it.

The air purification filter 80 also functions as a sound absorbing mechanism. That is, the air purification filter 80 can absorb the sound of the fan motor 32.

For example, if the air purification filter 80 is not provided, the sound of the fan motor 32 may leak from the exhaust port 16C of the underside 16, causing discomfort to customers.

In contrast, according to the oil smoke purification device 1 of this embodiment, an air purification filter 80 is provided between the blower 30 and the exhaust port 16C, so that the sound of the fan motor 32 is absorbed by the air purification filter 80, reducing the sound of the fan motor 32 leaking from the exhaust port 16C. This improves the comfort of customers.

The air purification filter 80 also functions as a speed reducing mechanism, i.e., it slows down the airflow generated by the blower 30.

For example, if the air purification filter 80 is not provided, the airflow generated by the blower 30 may collide with the floor surface at high speed, stirring up dust on the floor and causing discomfort to customers.

In contrast, in the oil smoke purification device 1 according to this embodiment, an air purification filter 80 is provided between the blower 30 and the exhaust port 16C, so that the airflow generated by the blower 30 is slowed down, and the stirring up of dust on the floor surface can be effectively prevented.

As described above, the oil smoke purifying device 1 according to this embodiment is placed on the floor of a restaurant. The oil smoke purifying device 1 includes a housing 10 having an air intake port at the top and an air exhaust port 16C at the bottom, a blower 30 arranged in the housing 10, an exhaust passage 40 through which the airflow generated by the blower 30 passes, a disk-shaped oil collection filter 50 having holes arranged upstream of the blower 30, and a motor 60 to which the oil collection filter 50 is detachably attached and which rotates the oil collection filter 50 at high speed. According to the oil smoke purifying device 1 configured as above, the oil collection filter 50 is rotated at high speed by the motor 60, so that oil can be suitably collected from the exhaust air flowing from the kitchen of the restaurant to the floor and the exhaust air generated by cooking at the customer tables. The oil collection filter 50 is not easily clogged, so that it can suitably collect oil smoke on the restaurant floor for a long period of time. Because the exhaust is performed from below the oil smoke purification device 1, it is possible to prevent the oil smoke from spreading over a wide area. As a result, it is possible to provide an oil smoke purification device 1 that can purify oil smoke on restaurant floors for a long period of time and prevent the oil smoke from spreading over a wide area.

The oil smoke purification device 1 further includes an air purification filter 80 (speed reduction mechanism) that is disposed downstream of the blower 30 and that slows down the airflow generated by the blower 30. With this configuration, the airflow generated by the blower 30 is slowed down, and it is possible to effectively prevent dust on the floor from being stirred up.

In addition, the exhaust port 16C is formed to exhaust air toward the floor surface. With this configuration, air is exhausted toward the floor surface through the exhaust port 16C, which can prevent smoke from diffusing and prevent the exhausted air from hitting customers and causing discomfort.

In addition, the exhaust port 16C is provided on the underside of the housing 10. With this configuration, since the exhaust port 16C is provided on the underside portion 16 of the housing 10, it is possible to prevent the exhausted air from hitting the feet of the customer, thereby preventing the customer from feeling uncomfortable.

The oil smoke purification device 1 further has legs 90 that support the housing 10. This configuration ensures space between the floor surface and the underside 16 of the housing 10, allowing air to be conveniently exhausted from the underside 16. In addition, cleaning is easier because it is less likely to come into contact with the housing 10 when cleaning the floor surface.

The present invention is not limited to the above-described embodiment, but may be modified in various ways within the scope of the claims.

For example, in the above-described embodiment, the oil smoke purification device 1 has an air purification filter (reduction mechanism) 80, but the oil smoke purification device does not have to have an air purification filter.

In addition, in the above-described embodiment, the exhaust port 16C is formed to exhaust air toward the floor surface, but the exhaust port does not have to be formed to exhaust air toward the floor surface.

In addition, in the above-described embodiment, the exhaust port 16C is provided on the underside of the housing 10, but the exhaust port does not have to be provided on the underside of the housing 10.

In addition, in the above-described embodiment, the oil smoke purification device 1 has legs 90, but the oil smoke purification device does not have to have legs.

In addition, in the above-described embodiment, the oil tray 73 was arranged adjacent to the oil guard 71. However, the location where the oil tray 73 is arranged is not limited, and it can be provided in any available space within the housing 10. In this case, the oil tray 73 is not contaminated by oil smoke, so it is possible to prevent it from becoming contaminated when collecting oil. In addition, since it can be provided in any available space in the housing 10, it is possible to make efficient use of the space.

Also, a tray larger than the area where the air is exhausted (corresponding to the ventilation cover 16B) may be provided below the legs 90. This configuration can prevent the high-temperature exhaust air exhausted from the exhaust port 16C from directly hitting the low-temperature floor surface, thereby preventing condensation on the floor surface.
