Description

  The present invention relates to a powder collecting apparatus that recovers powder used for adhering to a food such as fried food.

  When manually attaching the powder to food such as fried food, the operator drops the food in a container containing the powder, sprinkles the powder over the food container over the powder container, The work of knocking off the excess powder adhering to the food is performed at the top. During this operation, powder may be scattered around. As a device for preventing this, a device described in registered utility model No. 3005747 (Patent Document 1) is known.

  In the apparatus disclosed in this document, an air inlet is formed above a work table used for attaching powder to food. The intake port communicates with an air filter and a fan disposed above the intake port. Therefore, the powder that has risen around the work table is sucked from the air inlet and is captured by the air filter.

Registered Utility Model Publication No. 3005747

However, the conventional apparatus has the following problems.
First, the conventional apparatus has a configuration that sucks as much as possible the powder that has risen above the work table. As a result, a large amount of suction air flow is required, and as a result of using a fan for realizing this, power consumption increases.
Secondly, since a configuration is adopted in which all the powder that has risen above the work table is sucked, the amount of powder sucked from the intake port increases. This means that the clogging of the filter proceeds faster and the powder collection effect by the filter is reduced in a short time. Furthermore, if the cleaner is used to clean the filter to which the powder adheres, the cleaner will become clogged this time, and if the filter is washed with water, it will take time to dry the filter.
The present invention has been made in view of such problems, and has been made for the purpose of addressing at least one of the problems described above.

  A powder collecting apparatus according to the present invention is a powder collecting apparatus that collects powder used for adhering to a food, and is provided with a suction port provided to face an opening of a container that stores the powder, and the container And an obstacle disposed between the opening and the suction port so as to collide with powder that moves around the opening and moves toward the suction port.

(Embodiment 1)
1. Outline of the Powder Collection Device FIG. 1 is a front view schematically showing the configuration of the powder collection device according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view schematically showing the powder collecting apparatus shown in FIG. 1 when viewed from the AA ′ plane. FIG. 3 is a cross-sectional view schematically showing the powder collecting apparatus shown in FIG. 1 as viewed from the BB ′ plane.

  The powder collecting apparatus 100 according to the present embodiment is configured by a box-shaped housing 110 having a substantially L-shaped cross-sectional shape. The powder collecting apparatus constituted by such a housing 110 is roughly divided into a container 200 for storing a container for storing powder for adhering to a food material, and the periphery of the container stored by the container 200. A suction unit 300 that sucks air and a powder collection unit 400 that collects powder from the air sucked by the suction unit 300 are included.

2. Configuration of Storage Unit 200 The configuration of the storage unit 200 will be described.
The storage unit 200 includes a first container 210 that stores powder for adhering to the food, a sieving device 220 disposed below the first container 210, and a second container disposed below the sieving device 220. The container 230 is accommodated in the housing 110.

The first container 210 has an opening 210a on its upper surface. A plurality of holes 210b are formed on the bottom surface. These holes 210b are covered with a lid 210c provided detachably.
When the worker performs a dusting operation using the powder stored in the first container 210, the hole 210b is covered with the lid 210c so that the powder does not fall through the hole 210b. After the powdering operation is completed, the food pieces and balls accumulated in the first container 210 due to the powdering operation (powder that has solidified into a ball shape by absorbing water adhering to the surface of the food material) Is removed, the lid 210c is removed and the hole 210b is opened.

  The sieving device 220 collects food debris and balls, etc. by passing the powder mixed with the food debris and balls that have fallen through the holes 210b of the first container 210, and only the powder below. Drop into second container 230. As the sieving device 220, any type of device including an oscillating method (for example, Japanese Patent No. 3896273), a swinging method, a rotating swinging method, and the like can be used.

  Similarly to the first container 210, the second container 230 may have an opening 230a on the upper surface and a plurality of holes 230b on the lower surface. A lid 230c covering these holes 230b is detachably provided.

3. The structure of the powder collection part 400 The structure of the powder collection part 400 is demonstrated .
In the powder collection part 400, the surface 402 facing the opening 210a of the container 210 is formed. On this surface 402, for example, a rectangular suction port 410 is formed. The suction port 410 communicates with a hood 412 that extends upward from the vicinity of the center of the housing 110. The hood 412 has, for example, a shape that decreases the cross-sectional area as it goes upward.
The powder collection unit 400 includes a cyclone 420 that collects powder from the air sucked from the suction port 410 and passed through the hood 412, and a blower 430 that is connected to the cyclone 420 and applies a suction force to the cyclone 420.
For example, the cyclone 420 and the blower 430 are disposed inside the housing 110 so as to have a positional relationship in which the hood 412 is sandwiched therebetween.

3-1. Configuration of Cyclone 420 FIG. 4 is a perspective view schematically showing the configuration of the cyclone 420 used in the powder collecting apparatus 100 according to the present embodiment.
The cyclone 420 mainly includes an upper cylindrical portion 500, a lower cylindrical portion 510, a funnel portion 520, and a collection box 530.

  In the upper cylindrical portion 500, a hole 500b is formed in the bottom surface 500a. An exhaust port 500d is formed at the lower end of the side surface 500c. An exhaust pipe 502 is connected to the exhaust port 500d. The exhaust pipe 502 is connected to the blower 430 as will be described later.

In the lower cylindrical portion 510, a hole 510b is formed in the upper surface 510a. The hole 510 b communicates with the hole 500 b of the upper cylindrical portion 500.
A communication pipe 512 extending in the vertical direction is attached to the upper surface 510a. The communication pipe 512 communicates with the hole 500b of the upper cylindrical portion 500 through the hole 510b.
A suction port 510d is formed at the upper end of the side surface 510c. A suction pipe 514 is connected to the suction port 510d. The suction pipe 514 is connected to the hood 412 as will be described later.
Further, the lower end 510e of the lower cylindrical portion 510 is an open end.

  The funnel portion 520 has a diameter that decreases from the upper end 520a toward the lower end 520b. Both the upper end 520a and the lower end 520b are open ends. The upper end 520a communicates with the lower end 510e of the lower cylindrical portion 510.

  As an example, the collection box 530 has a cylindrical shape. A hole 530b is formed in the upper surface 530a. The hole 530b communicates with the lower end 520b of the funnel portion 520.

In the cyclone 420 having such a configuration, first, when the blower 430 connected to the exhaust pipe 502 is driven, air containing powder P is sucked into the lower cylindrical portion 510 from the suction pipe 514. Since the air containing the powder P is sucked into the lower cylindrical portion 510 in the tangential direction, a swirling flow is generated inside the lower cylindrical portion 510. The powder P placed on the swirling flow is affected by centrifugal force and gravity, and falls downward while being pressed against the inner wall of the lower cylindrical portion 510. On the other hand, the air carried in the swirl flow is drawn into the blower 430 through the exhaust pipe 502 after reaching the inside of the upper cylindrical portion 500 through the communication pipe 512.
Further, the powder P falling on the swirling flow from the lower cylindrical portion 510 to the funnel portion 520 falls while swirling along the inner wall of the funnel portion 520 and is collected in the collection box 530.

3-2. Configuration of Blower 430 FIG. 5 is a schematic diagram showing the configuration of the blower 430 used in the powder collecting apparatus 100 shown in FIG.
The blower 430 includes a motor part 432, a rotary blade part 434 connected to the motor part 432, a hollow part 436 communicating with the rotary blade part 434, and a suction port 438 and a discharge port 440 communicating with the hollow part 436. Including.
When the motor unit 432 is activated, the rotary wing unit 434 rotates. Thereby, air is sucked from the suction port 438. Air sucked from the suction port 438 passes through the hollow portion 436 and is discharged from the discharge port 440.
In addition, as the blower 430, not only what was shown in FIG. 5, but arbitrary blowers can be used.

3-3. Connection State Next, the connection state of the hood 412 (suction port 410), the cyclone 420 and the blower 430 will be described with reference to FIG. FIG. 6 is a schematic diagram conceptually showing a connection state of the hood 412, the cyclone 420, and the blower 430 used in the powder collecting apparatus 100 shown in FIG.

  The hood 412, the cyclone 420, and the blower 430 are each arranged at the position shown in FIGS. However, in FIG. 6, it should be noted that the positional relationship between these elements is different from that shown in FIGS.

The hood 412 is connected to the suction pipe 514 of the cyclone 420 by a pipe 602.
The exhaust pipe 502 of the cyclone 420 is connected to the suction port 438 of the blower 430 by a pipe 604.
A discharge port 440 of the blower 430 is connected to an exhaust pipe 608 by a pipe 606. For example, as shown in FIG. 2, the pipe 606 extends through the inside of the housing 110 to the bottom surface of the housing 110. The exhaust pipe 608 is disposed below the bottom surface of the housing 110. As a result, the exhaust from the blower 430 is discharged to the outside of the housing 110 via the pipe 606 and the exhaust pipe 608.

  With the connection as described above, air sucked from the suction port 410 (air mixed with powder) is sucked into the cyclone 420 from the suction pipe 514 through the hood 412 and the pipe 602. The powder contained in the inhaled air is collected in the collection box 530. The air from which the powder is removed is discharged from the cyclone 420 through the exhaust pipe 502. The air discharged from the cyclone 420 is sucked into the blower 430 through the suction port 438 and discharged from the blower 430 through the discharge port 440. The air discharged from the blower 430 is discharged from the exhaust pipe 608 to the outside of the housing 110 via the pipe 606.

  In FIGS. 1 to 3, the pipes 602 to 606 are represented by simple lines for convenience, but each pipe has the same configuration as the pipe 602 as shown in FIG. 6. The same applies to the pipes 604 and 606 in FIG.

4). Suction unit 300
Next, the configuration of the suction unit 300 will be described with reference to FIGS.
FIG. 7 is a perspective view schematically showing a configuration of the suction unit 300 used in the powder collecting apparatus 100 shown in FIG. 1 and its surroundings. FIG. 8 is a front view schematically showing the configuration of the suction unit 300 shown in FIG. 7 and its surroundings. FIG. 9 is a cross-sectional view schematically showing the configuration of the suction unit 300 shown in FIG. 8 and its periphery when viewed from the CC ′ plane.

  A surface 402 is disposed above the upper surface 210a of the first container 210 and at a position facing the upper surface 210a. A suction port 410 is formed on the surface 402. Here, as an example, the suction port 410 is positioned above the upper surface 210a of the first container 210, but is not positioned directly above the upper surface 210a (that is, in the depth direction Y, suction In the case where there is no overlapping region between the mouth 410 and the upper surface 210a). However, the positional relationship between the suction port 410 and the upper surface 210a may be changed so that an overlapping region is generated between the suction port 410 and the upper surface 210a in the depth direction Y.

Furthermore, the connection face 600 which connects the vicinity of the rear end 210a ₁ of the rear end 402a and the upper surface 210a of the surface 402 is formed. A sidewall 604 extends forward from the right end 600R of the connection surface 600, and similarly, a sidewall 608 extends forward from the left end 600L of the connection surface 600.

  In addition, an obstruction part 610 is provided between the surface 402 and the upper surface 210 a of the first container 210. The blocking unit 610 is disposed on the connection surface 600. The blocking portion 610 includes a collision surface 612 that intersects a region R (the hatched portion in FIG. 9) that connects the suction port 410 and the upper surface 210a (as best shown in FIG. 9), The collision surface 612 is formed continuously with an object having a guide surface (guide surface) 614 facing the suction port 410.

The collision surface 612 intersecting the region R is provided for the purpose of acting as follows.
When the worker performs a dusting operation on the food F, the powder rises around the upper surface 210a of the first container 210 (particularly above the upper surface 210a). Part of the powder that rises around the upper surface 210 a and is sucked and moved toward the suction port 410 will collide with the collision surface 612. The powder that has collided with the collision surface 612 falls into the first container 210 located below the collision surface 612 (in this sense, the collision surface 612 is moved to the first container as shown in FIGS. It is desirable to arrange it at a position adjacent to the container 210).
For example, the powder P ₁ shown in FIG. 9 is powder that collides with the collision surface 612 while moving toward the suction port 410, and falls toward the first container 210 located below after the collision. On the other hand, the powder P ₂ shown in FIG. 9 is powder that does not collide with the collision surface 612 when moving toward the suction port 410 and is sucked into the suction port 410 as it is.

Thus, the collision surface 612 acts to reduce the probability that the powder that has risen around the upper surface 210 a of the first container 210 is sucked into the suction port 410.
The shape of the disturbing portion 610 shown in FIGS. 7 to 9 is merely an example. Based on the desired amount of powder sucked into the suction port 410, the shape of the collision surface 612 that intersects the region R can be changed.
For example, if the height and / or width of the collision surface 612 is increased (decreased), the probability that the soared powder collides with the collision surface 612 becomes higher (lower), so the amount of powder sucked into the suction port 410 Decreases (increases).
Further, if the angle formed by the collision surface 612 with respect to the upper surface 210a of the first container 210 is decreased (increased), the probability that the soared powder collides with the collision surface 612 is increased (lower), and thus the suction port 410 The amount of powder sucked in decreases (increases). In addition, if the angle formed by the collision surface 612 with respect to the upper surface 210a of the first container 210 is decreased, the probability that the soared powder hits the collision surface 612 and then returns to the first container 210 is increased. You can also.
In the example shown in FIGS. 7 to 9, the amount of powder sucked into the suction port 410 can be reduced while maintaining the working environment of the worker above the first container 210. Therefore, the collision surface 612 is formed so as to form an angle of approximately 90 degrees with respect to the upper surface 210a of the first container 210.

  The blocking unit 610 is provided for the purpose of blocking the soared powder from colliding with the collision surface 612, that is, preventing the soared powder from being sucked into the suction port 410. Therefore, it is not essential that the collision surface 612 and the guide surface 614 are flat surfaces as shown in FIGS.

  In the present embodiment, as the most preferable mode, a mode in which a method of providing a disturbing part having a collision surface and a method of providing a cyclone has been described. However, the present invention includes a form using at least one of these methods. That is, the filter according to the related art may be combined with the disturbing part having the collision surface, and conversely, only the cyclone may be used without using the disturbing part having the collision surface.

As described above, according to the present embodiment, the collision surface that collides with the powder moving toward the suction port is provided in the region between the container that stores the powder and the suction port facing the container. The amount of powder sucked into the suction port can be suppressed. This eliminates the need for a fan having a large amount of suction air, thereby reducing power consumption.
Moreover, by providing the collision surface at a position adjacent to (close to) the container, the amount of powder that collides with the collision surface and returns to the container can be increased.

  In this embodiment, a cyclone can be used instead of the filter. By using a cyclone, it is possible to avoid the occurrence of various problems described above due to the use of a filter. Furthermore, by using a cyclone, powder can be recovered from the air (air mixed with powder) sucked into the cyclone and reused.

(Embodiment 2)
In the present embodiment, a case will be described in which powder is prevented from scattering around the powder collecting apparatus.
Hereafter, it demonstrates paying attention only to the structure different from the powder collection apparatus which concerns on Embodiment 1 among the structure of the powder collection apparatus which concerns on this Embodiment.

FIG. 10 is a perspective view schematically showing the configuration of the suction unit and its periphery in the powder collecting apparatus according to Embodiment 2 of the present invention.
The powder collecting apparatus 700 according to the present embodiment includes an airflow generating element that generates an airflow toward the suction port 410 along the periphery of the opening 210 a of the first container 210.

  FIG. 10 shows a first pipe 710 disposed near both ends (right end and left end) of the opening 210a of the first container 210 as a specific example of the airflow generating element. The first pipe 710 is a pipe that conveys air and is formed with an exhaust hole 712 that discharges the air toward the suction port 410. The exhaust hole 712 may be a linear exhaust hole extending along the extending direction of the first pipe 710, or may be a plurality of dot-like shapes arranged along the extending direction of the first pipe 710. It may be a discharge hole.

The first pipe 710 forms an air flow S ₁ that flows from the first pipe 710 toward the suction port 410. By forming this air flow S ₁ , the powder that has risen around the first container 210 (particularly upward) moves toward the suction port 410 along the air flow S ₁ . As a result, it is possible to suppress the situation where the powder that has risen around the first container 210 is scattered around the powder collecting apparatus 700. Incidentally, the powder moving toward the suction port 410 ride on the air current S ₁ is, when colliding with the interference portion 610 (in particular the impact surface 612), it becomes possible to return to the first container 210 to fall Needless to say.

FIG. 10 shows a second pipe 720 and a guide plate 730 provided corresponding to the second pipe 720 as another specific example of the airflow generating element. The configurations of the second tube 720 and the guide plate 730 will be described with reference to FIGS. 11 and 12 in addition to FIG.
FIG. 11 is a cross-sectional view schematically showing the configuration of the second tube 720 and the guide plate 730 in the powder collecting apparatus shown in FIG. FIG. 12 is a perspective view schematically showing the configuration of the guide plate 730 in the powder collecting apparatus shown in FIG.

  As shown in FIG. 10, the second tube 720 is attached to the outer surface 110a of the housing 110 along the horizontal direction (as an example, along the horizontal direction). The 2nd pipe | tube 720 is a pipe | tube which conveys air, Comprising: The exhaust hole 722 which discharges | emits air upwards is formed. The exhaust hole 722 may be a linear exhaust hole extending along the extending direction of the second pipe 720, or may be a plurality of dot-like shapes arranged along the extending direction of the second pipe 720. It may be a discharge hole.

The guide plate 730 is attached to the outer surface 110a of the housing 110 along the lateral direction so as to face the second tube 720 above the second tube 720. The guide plate 730 is preferably provided so as to extend substantially parallel to the second tube 720.
As shown in FIGS. 11 and 12, the guide plate 730 is formed continuously with the front plate portion 732 and the front plate portion 732 that extend with a gap between the guide plate 730 and the outer surface 110 a of the housing 110, and the suction port 410. A rear plate portion 734 inclined toward the front side, and a fixing portion 736 formed continuously with the front plate portion 732. A screw hole 736a formed in the fixing portion 736 is used to attach the guide plate 730 to the outer surface 110a of the housing 110 in a detachable manner using screws.

According to the second tube 720 and the guide plate 730 having such a configuration, an air flow toward the suction port 410 is generated as follows. That is, as shown in FIG. 11, the air S ₂₁ is exhausted upward from the exhaust hole 722 of the second pipe 720. The exhausted air S ₂₁ passes through a gap between the inner surface of the front plate portion 732 of the guide plate 730 and the outer surface 110a of the housing 110, and then collides with the inner surface of the rear plate portion 734, thereby changing the traveling direction. bend (S _22). The air S ₂₂ bent in the traveling direction is guided to the inner surface of the rear plate portion 734 and proceeds toward the suction port 410 (S ₂₃ ). Air S ₂₃ shown in FIG. 11, to form a stream S ₂ as shown in FIG. 10.

By forming the air flow S ₂ , the powder that has risen around the first container 210 (particularly upward) moves toward the suction port 410 along the air flow S ₂ . As a result, it is possible to suppress the situation where the powder that has risen around the first container 210 is scattered around the powder collecting apparatus 700. Incidentally, the powder moving toward the suction port 410 ride on the air current S ₂ is, when colliding with the interference portion 610 (in particular the impact surface 612), it becomes possible to return to the first container 210 to fall Needless to say.

  As another embodiment, it is of course possible to arrange the second pipe 720 near the front end of the opening 210a of the first container 210 (in this case, the exhaust hole 722 of the second pipe 720 is sucked). The second tube 720 can be arranged to face the mouth 41). However, by employing the second tube 720 and the guide plate 730 as in the present embodiment, the following advantages can be obtained.

As shown in FIG. 10, a space 112 for accommodating the first container 210 is formed in the housing 110. This space 112 communicates with the outside through an opening 114 formed in the outer surface 110 a of the housing 110. Thus, when the operator removes the first container 210 for cleaning or the like, the operator simply slides the first container 210 toward the front without lifting the opening 114 (that is, the passage port 114). ) Can be removed. In order to realize this, the opening 114 needs to be opened so that the first container 210 can pass through the opening 114. Here, if the second tube 720 is disposed in the vicinity of the front end of the opening 210 a of the first container 210, the movement of the first container 210 is hindered by the presence of the second tube 720.
Therefore, in the present embodiment, the second tube 720 is disposed below the opening 114, and a guide plate 730 that can be more easily removed is detachably attached to the housing 110 so as to block the opening 114. According to this configuration, when the operator removes the first container 210, the opening 114 is opened by removing the guide plate 730. Therefore, the opening 114 is opened by sliding the first container 210. Can be removed.

Next, air supply to the first tube 710 and the second tube 720 described above will be described with reference to FIGS. 13 and 14.
FIG. 13 is a cross-sectional view schematically showing a configuration of a powder collecting apparatus 700 according to Embodiment 2 of the present invention. FIG. 14 is a schematic diagram conceptually showing a connection state between the blower 430, the first pipe 710, and the second pipe 720 in the powder collecting apparatus according to Embodiment 2 of the present invention.

As shown in FIG. 13, the exhaust from the blower 430 described in Embodiment 1 is supplied to the first pipe 710 and the second pipe 720.
Such supply of exhaust gas can be realized by, for example, the configuration shown in FIG. A pipe 800 is connected to the exhaust port 440 of the blower 430. A branch pipe 802 is connected to the pipe 800.
Pipes 804, 806, and 808 are connected to the branch pipe 802. The pipes 804 and 806 are connected to corresponding first pipes 710 via air throttle valves 810 and 812, respectively. The pipe 808 is connected to the branch pipe 814.
Pipes 816 and 818 are connected to the branch pipe 814. The pipe 816 is connected to the second pipe 720 via the air throttle valve 820. The pipe 818 is connected to the exhaust pipe 608 described in Embodiment 1.
Note that in FIGS. 13 and 14, each pipe is represented by a simple line for convenience.

  In the present embodiment, as the most preferable mode, a method of providing an air flow generating element (a first tube 710, a second tube 720, a guide plate 730, etc.) that generates an air flow toward the suction port 410, and a collision surface 612 are provided. The form which combined the technique which provides the obstruction part 610 which has is demonstrated. However, the present invention includes a form using at least one of these methods. That is, the airflow generating element that generates the airflow toward the suction port can be used in combination with the obstructing portion, or can be used alone without being combined with the obstructing portion.

  As described above, according to the present embodiment, the air flow from the periphery (a part or the whole of the periphery) of the container that stores the powder to the suction port soars around the container. Since the powder rides on the airflow and moves to the suction port, it is possible to suppress the situation where the powder is scattered around the powder collecting apparatus.
