Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste processing machine for reducing the amount of food waste that has been thrown in, and more particularly to a relatively large food waste processing machine for business use.

[0002]

2. Description of the Related Art A method for reducing the amount of food waste, such as leftover food, scraps of vegetables and fruits, and bones and shells of seafood, which are generated in households, restaurants, food processors, etc., is disclosed, for example, in Japanese Patent Laid-Open No. 10-
A large number of food waste processing machines as described in Japanese Patent No. 156319 have already been proposed.

The food waste disposer disclosed in Japanese Unexamined Patent Publication No. 10-156319 has a processing tank containing a processing medium (carrier) in which microorganisms inhabit, and by introducing the garbage into the processing tank, This is to reduce the amount of food waste by decomposing food waste by the decomposition action of microorganisms.

[0004]

In recent years, the so-called Food Recycling Law (May 2001) came into effect, and among food-related businesses (eg, manufacturing, distribution, food service industries, etc.), the amount of food products wasted annually. It is said that operators with a capacity of 100 tons or more will be able to set numerical targets and make recommendations, public announcements and orders if the efforts are significantly insufficient. Against this background, there is an increasing need for a relatively large-sized food waste processing machine for business use these days.

[0005] In the garbage disposal, since garbage is treated, it is important to take measures against offensive odors in consideration of the surrounding environment. Therefore, a deodorizing device that removes odorous components (for example, ammonia gas) contained in the exhaust gas from the treatment tank is an extremely important constituent element for the garbage disposal. In particular, in the above-described commercial food waste disposal machine for which the needs are increasing, the processing amount of the food waste is large, and therefore the countermeasure against the malodor becomes a more remarkable problem. Therefore, a large deodorizing device is required according to the amount of processed garbage, and in some cases, the deodorizing device may have to be provided as a separate device from the processing machine main body.

[0006] As described above, a commercial garbage processor having a large processing amount requires a large installation space because the processing machine itself is large and a large deodorizing device corresponding to it is required. Will be.

The present invention has been made in view of the above matters, and an object thereof is to provide a food waste processing machine which can be made compact to save space.

[0008]

[Means for Solving the Problems] (1) In order to achieve the above object, the present invention is a food waste processing machine for reducing the amount of food waste that has been input, which has an input port for the above-mentioned food waste. A main body cover, a processing tank disposed in the main body cover so as to be close to a side wall on one side in the longitudinal direction of the main body cover, and a processing tank for reducing the weight of the input food waste, and provided in the processing tank, A stirring device having a rotating shaft arranged substantially horizontally so as to be substantially parallel to the longitudinal direction of the main body cover, and a stirring blade attached to this rotating shaft, and stirring the contents of the processing tank by the stirring blade; A controller provided in a position close to a side wall on the other side in the longitudinal direction of the body cover in the body cover, and a space formed by the controller and the processing tank in the body cover, the output thereof axis A drive unit having a drive shaft orthogonal and a driving device provided along the lateral direction of the body cover.

In the present invention, in the main body cover, the processing tank is arranged at a position close to one side wall in the longitudinal direction of the main body cover, and the control device is arranged at a position close to the other side wall in the longitudinal direction of the main body cover. Are installed. Normally, the processing tank has a large occupied area with respect to the control device, so that a space formed by the processing tank and the control device is formed on the same side as the control device (the other side in the longitudinal direction of the main body frame). A drive unit is provided in this space.

That is, in the present invention, the drive unit and the control unit of the stirring device are provided on the same side in the longitudinal direction in the main body cover, and the exclusive space of the drive unit and the control unit in the longitudinal direction of the main body cover is shared. ing. Thereby, as compared with the case where the control device and the drive device are provided on the opposite sides of the processing tank in the main body cover, the longitudinal dimension of the main body cover (that is, the longitudinal dimension of the garbage processing machine) Can be reduced.

Further, as a driving device for the stirring device for stirring the contents of the processing tank, a driving device in which an output shaft and a driving shaft are substantially orthogonal to each other is used. The drive device is arranged so that the drive portion of the drive device extends along the lateral direction of the main body cover (in other words, substantially parallel to the other side wall surface in the main body cover longitudinal direction). Generally, in a drive device, a drive shaft and an output shaft are often coaxial or substantially parallel to each other via a reduction gear. That is, in the drive device used in the present invention, since the drive shaft is substantially orthogonal to the output shaft, the drive shaft and the output shaft can reduce the dimension of the output shaft in the axial direction as compared with the drive device in the same direction. The space occupied by the drive device in the longitudinal direction of the body cover can be reduced. Therefore, by disposing the drive device in which the output shaft and the drive shaft are substantially orthogonal to each other as described above, the longitudinal dimension of the main body cover (that is, the longitudinal dimension of the food waste disposer) can be shortened.

As described above, according to the present invention, the size of the food waste disposer in the longitudinal direction can be shortened, and the food waste disposer can be made compact and its occupied area can be reduced. Therefore, the installation space can be saved. can do.

It is composed of a solenoid valve 83 (see FIG. 12 below) provided on the way. The solenoid valve 83 is opened and closed by a command signal from the control device 45. In the present embodiment, as an example, the control device 45 outputs a command signal to the solenoid valve 54 so as to supply water at fixed time intervals at set time intervals. However, it is preferable that the solenoid valve 83 be manually operated by the operation panel 13. The amount of water supplied by the water supply device 80 is also calculated by the control device 45 from the detection signal of the flow meter 55 (see FIG. 12 below).

Reference numeral 85 denotes a temperature sensor (see FIG. 11) for detecting the temperature of the deodorizing medium. This temperature sensor 85 is provided on the side wall (left side wall in FIG. 11) of the deodorizing tank 70 where the deodorizing medium is accommodated. It is provided. This temperature sensor 8

Reference numeral 86 is a known sterilizing filter for sterilizing exhaust gas, and the sterilizing filter 86 is provided in a filter container 87. This filter container 87 and the deodorizing tank 7
The space between the net 72 and the filter 76 at the lower part of 0 is connected by a duct 88. Also, the filter container 8
The downstream side of 7 (upper side in FIG. 11) is connected to an exhaust stack 90 via a duct 89. That is, the exhaust gas that has passed through the sterilizing filter 86 and is cleaned is finally discharged to the atmosphere from the exhaust pipe 90 via the duct 89.

The configuration of the food waste disposing machine according to the present embodiment is as described above. However, when it is used for commercial purposes, for example, in a restaurant or a food processor, it depends on the amount of food waste to be processed. It is also envisioned that the garbage processor will be upsized. In this case, in the food waste disposer of the present embodiment, the position of the food waste input port 27 (see FIG. 5) becomes high, and when a relatively large amount of food waste is input, the load operation is burdened. May occur. Therefore, in consideration of the throwing property of the raw garbage, a reverse throwing device 95 for throwing the raw garbage may be separately provided as conceptually shown in FIG.

This reversing and charging device 95 is, in general, for raising and lowering a container (container) 96 that has received food waste from the ground level to the charging height. When the container 96 is raised to the charging height. , Its container 96
Is turned over (inclined) above the loading lid 10 and the food waste in the container 96 is loaded into the processor body 1.
Of course, when throwing in the garbage, the throwing lid 10 is opened. When such a reversal charging device 95 is separately provided,
The raising / lowering and reversing operations of the container 96 and the opening / closing operation of the closing lid 10 may be interlocked with each other.
, The opening operation of the closing lid 10, the reversing operation of the container 96, etc. may be individually instructed.

Next, the operation of the food waste processor of this embodiment will be described below. FIG. 12 is a block diagram showing the overall configuration of the food waste disposer according to the present embodiment, and parts corresponding to parts similar to those in the previous drawings are designated by the same reference numerals. In FIG. 12, when performing garbage processing, first, a predetermined operation is performed on the operation panel 13, and the garbage to be subjected to fermentation decomposition processing is put into the processing tank 20. At this time, when the reversal charging device 95 is provided, the user first sets the container 96 containing the garbage in the reversal charging device 95. Then, when a predetermined operation is performed on the operation panel 13, the control device 45 causes the operations of the reversing loading device 95 and the opening / closing lid 10 to interlock with each other, and automatically loads the garbage in the container 96 into the processing tank 20. However, as described above, the reversal charging device 95
And the operation of the opening / closing lid 10, the posture and position of the container 96,
The operation panel 13 may be manually operated individually while visually checking the state of the opening / closing lid 10.

When the garbage is put in, the control device 45
A command signal is output to the drive device 36 to rotate the stirring device 30 for a fixed time. The detection of the input of garbage may be detection of opening / closing of the opening / closing lid 10 by the limit switch 12 or weight detection by the load cell 50. The introduced garbage is appropriately stirred with the treatment medium to ensure the frequency of contact with the microorganisms in the treatment medium, and the microorganisms reduce the weight (decomposition treatment).

In order to realize a good decomposition treatment of food waste during operation, it is necessary to maintain the habitat of the microorganism in a good state and activate the microorganism. Examples of the habitat environment of microorganisms include aeration of the treatment medium, temperature environment, and humidity environment. Therefore, the food waste disposer performs the following operations during operation.

First, in order to ensure the air permeability of the treatment medium, to make the water distribution in the treatment medium uniform, to supply fresh oxygen to the microorganisms, and to make the humidity environment uniform, the food waste and the treatment medium are Is appropriately stirred by the stirring device 30. The stirring operation of the stirring device 30 is controlled according to a program stored in the control device 45, for example.
Specifically, for example, stirring is performed at a rotation speed of about 1 to 3 rpm for about 1 to 2 minutes per hour. If necessary, the operation panel 13 appropriately drives the stirring device 30.

In order to maintain a suitable temperature environment,
The processing tank 20 is appropriately heated by the heater 56. The operation control of the heater is performed by the control device 45. For example, when it is determined that the processing medium temperature is below the proper range based on the detection signal of the temperature sensor 21a, the control device 45 turns on the heater 56. When it is in the proper range (or when it returns to the proper range), the control device 45
Turns off the heater 56.

In order to maintain a suitable humidity environment,
Water is appropriately supplied to the treatment medium by the water supply device 51 (see FIG. 5). The operation of the water supply device 51 is also performed by the control device 45. For example, the water content of the processing medium is estimated based on the detection signal of the load cell 50, and when it is determined that the estimated value is below the appropriate range, the solenoid valve 54 is opened to supply water to the processing medium. The amount of water supply is based on the detection signal of the flow meter 55
5 is calculated. In addition, when water is supplied, the control device 45 adjusts the water content of the treatment medium to be uniform.
A command signal is output to the drive device 36, and the stirrer 30 stirs the food waste and the processing medium for a certain period of time.

The inside of the processing tank 20 is ventilated in order to supply fresh oxygen to the microorganisms. That is, oxygen is supplied into the processing tank 20 by the intake air (outside air) introduced from the intake port 17 (see FIG. 4) through the intake pipe line 18, and the gas and the like generated by the decomposition process of the garbage are exhausted. The gas is exhausted to the outside of the processing tank 20 via the hose 4. This ventilation is exhaust fan 6
Promoted by 6. The rotation speed of the exhaust fan 66 is controlled by the controller 45 according to the weight detected by the load cell 50. As a result, a required amount of oxygen according to the amount to be processed is supplied into the processing tank 20. In addition, the intake pipe line 18
In accordance with the detection signal of the air flow meter 19a provided in the exhaust fan 6
It is also conceivable to control the rotation speed of No. 6.

Exhaust gas from the processing tank 20 is discharged from the deodorizing unit 2
Will be introduced to. The exhaust gas guided to the deodorizing unit 2 is first subjected to dust removal by the first and second filters 64 and 65 (see FIG. 10) of the filter unit 61 (see FIG. 10). After that, the exhaust gas from which the dust is removed is exhausted by the exhaust fan 66.
It is introduced into the deodorizing tank 70 via. When passing through the deodorizing tank 70, the odorous components contained in the exhaust gas are decomposed and removed by the microorganisms mixed in the deodorizing medium. The deodorized exhaust gas is sterilized through the sterilization filter 86 and then discharged into the atmosphere from the exhaust stack 90 (see FIG. 10).

In order to maintain the deodorizing performance of the deodorizing medium, it is necessary to maintain a suitable habitat for the microorganisms in the deodorizing medium. Therefore, the temperature and humidity of the deodorizing medium are controlled during operation. Specifically, the temperature of the deodorizing medium is calculated by the control device 45 based on the detection signal of the temperature sensor 85,
The user monitors it with the operation panel 13 or the like as necessary. In addition, the deodorizing medium is supplied with water by the water supply device 80 (see FIG. 11) at regular intervals. This water supply amount is calculated by the control device 45 based on the detection signal of the flow meter 55.

The food waste processor of this embodiment decomposes food waste as described above to reduce or eliminate it.

The operation and effect of this embodiment described above will be sequentially described below. (1) Compactification In the present embodiment, the processing tank 20 is arranged in the main body cover 6 at a position close to the side wall on one side in the longitudinal direction of the main body cover 6, and the treatment tank 20 is disposed on the other side in the longitudinal direction of the main body cover 6. The control device 45 is arranged at a position close to the side wall. Since the processing tank 20 has a large area occupied by the control device 45,
A space formed by the processing tank 20 and the control device 45 is formed on the same side as the control device 45 (the other side in the longitudinal direction of the main body frame 6). The drive unit 36 is provided in this space.

That is, in the main body cover 6, the drive device 36 and the control device 45 of the stirring device 30 are provided on the same side in the longitudinal direction in the main body cover 6 (that is, both are on the right side in FIG. 4). As a result, the space occupied in the longitudinal direction of the main body cover 6 is reserved in the drive device 36 and the control device 4.
5 are trying to share. By arranging in this way, compared with the case where the control device 45 and the drive device 36 are provided on the opposite sides of the processing tank 20 in the main body cover 6, the longitudinal dimension of the main body cover 6 ( That is, the longitudinal size of the garbage processing machine, the horizontal direction in Fig. 4)
Can be reduced.

Further, as the drive device of the stirring device 30, a drive device 36 in which the output shaft 39 and the drive shaft (inside the drive portion 37) are substantially orthogonal to each other is used. And this drive device 3
6 is arranged so that the output shaft 39 is substantially parallel to the rotation shaft 31 of the stirring device 30 and the axis of the drive shaft in the drive unit 37 is substantially orthogonal to the rotation shaft 31 of the stirring device 30.
Generally, in a drive device, a drive shaft and an output shaft are often coaxial or substantially parallel to each other via a reduction gear. Therefore, in the drive device 36 used in the present embodiment, the drive shaft is substantially orthogonal to the output shaft 39, so that the drive shaft and the output shaft are in the axial direction of the output shaft 39 as compared with the drive device in the same direction. Can be shortened, and the space occupied by the drive device 36 in the longitudinal direction of the body cover 6 can be reduced. In this way, the drive device 36 in which the output shaft 39 and the drive shaft are substantially orthogonal to each other
By arranging in the above-mentioned layout, the longitudinal dimension of the main body cover 6 (that is, the longitudinal dimension of the food waste disposer, the lateral dimension in FIG. 4) can be shortened.

As described above, according to the present embodiment, the longitudinal size of the food waste disposer can be shortened, the food waste disposer can be made compact, and the occupied area can be reduced, so that the installation space can be saved. It can be made into a space.

(2) Improvement of maintainability As described above, the driving device 36 and the control device 45 of the stirring device 30 are provided on the same side in the longitudinal direction in the body cover 6 (that is, both are on the right side in FIG. 4). There is. An opening / closing door 6a is provided on a side wall (that is, a side wall on the right side in FIG. 4) of the main body cover 6 in which the drive device 36 and the control device 45 are arranged close to each other.
Is provided. That is, the drive device 36 and the control device 45 are both exposed to the outside when the opening / closing door 6a is opened. Therefore, the maintenance of the drive device 36 and the control device 45, which are one of the main devices in the built-in equipment on the processor main body 1 side, can be facilitated.

The opening / closing door 6a is the same as that of the main body cover 6 shown in FIG.
It occupies almost the entire area of the middle right side surface, and this side surface can be widely opened, which also contributes to improvement of maintainability.

(3) Ensuring the degree of freedom of layout Since the drive device 36 and the control device 45 are provided on the same side, the opening / closing door 6a is also used as a door for maintenance of the drive device 36 and the control device 45. be able to. If the drive device 36 and the control device 45 are provided on the opposite sides of the processing tank 20, the doors for the respective inspections are required. In the present embodiment, if such a configuration is adopted, it is necessary to provide opening / closing doors on the left and right side surfaces in FIG.

In this case, in the present embodiment, the deodorizing device is provided as a separate device (deodorizing unit 2) from the processor main body 1, so the layout of the deodorizing unit 2 is as follows.
It will be limited. That is, since the reversing charging device 95 (see FIG. 12) described above may be installed on the front side of the processor main body 1, and the operation panel 13 (see FIG. 1) is also present, the front side can be arranged. Is hard to think of. Therefore, when the deodorizing unit 2 is arranged close to the processor main body 1, the deodorizing unit 2 is inevitably laid out on the back side (upper side in FIG. 2) of the processor main body 1. Even if the processing machine main body 1 is arranged on the side surface in the longitudinal direction, it is necessary to secure a space for opening and closing the opening / closing door.
And the deodorizing unit 2 must be placed at a distance.

On the other hand, in the present embodiment, the door for inspection of the drive unit 36 and the control unit 45 can be shared by the single opening / closing door 6a, and the side surface on the opposite side (left side in FIG. 2) is free. Can be As a result, even if the deodorizing unit 2 is arranged close to the processing machine main body 2, it is selective with respect to the side surface side (left side in FIG. 2 in this example) and rear surface side (upper side in FIG. 2) of the processing machine main body 1. The deodorizing unit 2 can be laid out. Thereby, the degree of freedom of layout can be secured.

In the present embodiment, the above (2)
Regarding the function and effect of (3), the opening / closing door 6a is provided on the side surface of the main body cover 6, but the essential effect of the present invention is that the installation space is saved and the position of the opening / closing door is It is not limited to the presence or absence.

In the above description, a food waste disposer in which the deodorizing device is a separate device from the disposer main body has been described as an example, but the deodorizing device is not limited to this, and the deodorizing device and the disposer main body have an integral structure. The present invention can be applied even to a garbage processor or a type of garbage disposal without a deodorizing device. Similarly,
The present invention can be applied even to a food waste disposer that does not include a water supply device for a medium, a heater for a medium container, an exhaust fan, or the like. Further, the present invention can also be applied to a food waste disposer that uses equipment of a type different from that of this embodiment as a water supply device, a heater, an exhaust fan, and the like. Similar effects are obtained in these cases. In short, the essence of the present invention is that the drive unit and the control unit are provided on the same side, and that the drive unit also uses an axis-orthogonal type whose output shaft direction dimension is short.

Further, in the above description, the garbage processing machine for reducing the garbage by the decomposition action of microorganisms has been described as an example. However, the present invention is not limited to heating or blowing hot air. It can also be applied to a food waste processing machine having a different processing method, such as a so-called dry type in which waste is dried to reduce the weight. Of course, it can be applied to both a relatively small one for home use and a relatively large one for business use. In short, as long as it does not deviate from the technical idea, the present invention is applicable as long as it is a method of reducing the amount of garbage put in by some method and provided with a control device and a drive device of built-in equipment. Therefore, the same effect can be obtained.

According to the present invention, the drive unit and the control unit are provided on the same longitudinal side in the main body cover, so that the drive unit and the control unit share the exclusive space in the main body cover in the longitudinal direction. Can be made. Further, by using a drive device in which the output shaft and the drive shaft are substantially orthogonal to each other and the dimension of the output shaft in the axial direction is shortened, the dimension of the main body cover in the longitudinal direction of the drive device is shortened. be able to. Therefore, the longitudinal dimension of the food waste disposer can be shortened. As a result, the garbage processor can be made compact and the space can be saved.

Further, since the drive device and the control device of the stirring device are provided on the same side in the longitudinal direction of the main body cover, the drive device and the control device are provided on the side wall of the main body cover in which the drive device and the control device are arranged close to each other. It is possible to provide an opening / closing door that can be commonly used for maintenance of the device. Thereby, the maintainability of the drive device and the control device can be improved.
