DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a garbage disposer.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 5-317835 discloses a conventional garbage disposal machine.

[0003] The structure of the garbage processing apparatus will be described below with reference to FIG.

In the figure, reference numeral 61 denotes a garbage disposal apparatus main body, a garbage disposal apparatus main body 61 has a garbage processing tank 62, a lid 63 for covering the upper part of the processing tank, and a condensing section 64 inside the processing tank 62. Heating device 65 (here microwave oscillator), deodorizer 66
Etc.

When a user uses the garbage disposal apparatus, first, the lid 63 is opened, and garbage is introduced into the treatment tank 62 through an inlet 67.

At this time, the temperature of the processing tank 62 is measured by a temperature detector 68.
Has been measured by

Accordingly, if the temperature in the processing tank 62 falls below the set value due to the loading of the load, it is detected, the heating device 65 is started, the processing tank is heated, and the water contained in the food waste is evaporated to remove the food waste. Efficient drying and weight reduction.

[0008] In this process, the steam discharged from the garbage is cooled in the condensing section 64 and returned to water droplets. That is, the condenser 64
Is separated from the processing tank 62 by a heat insulating material 69 such as a vacuum heat insulating material, and the front side is cooled by a cooling fan 70. Therefore,
When the steam in the processing tank 62 reaches the condensing section 64, it is rapidly cooled and adheres to this portion as dew water. The collected dew water is guided from a drain port 71 to a water storage tank (not shown) or the like.

On the other hand, the air from which moisture has been removed is supplied to the suction fan 72.
The air is further sucked into the deodorizer 66, and the air deodorized by the deodorizer 66 is released into the atmosphere (in the room). In other words, the processing tank 62
The odor generated inside is contained in the water vapor, passes through the condensation section,
It is configured to be discharged to the outside as water or returned to the room via the deodorizer 66.

[0010]

In a food waste disposer having components such as a treatment tank, a stirring rod, a stirring shaft, a stirring shaft transmission, a transmission, a motor transmission, and a drive motor, steel materials are often used. As a result, the weight increases and it takes time to move and install as general household goods. In addition, the space below the processing tank becomes a dead space,
Since the motor transmission is large, the garbage disposal machine is large, and the installation area is also large.

In addition, in the stirring shaft transmission, when an overload is applied to the stirring bar, it is required to detect a rotation abnormality of the stirring shaft before the stirring bar is broken, but the detection cannot be performed well.

Further, in the case of using a steel roller chain for the transmission, noise is large in addition to weight.
The cost is high, or the photo sensor for detecting the abnormality of the stirring shaft is deteriorated in the dirt detection performance by oil for the roller chain. Further, in the case of using a combination of steel gears for the motor transmission, in addition to the weight, vibration and noise due to the rotation of the gears are high, and maintenance and inspection are difficult because a large number of gears are used.

[0013]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems.

That is, the inside of the processing tank is divided into two tanks by a partition plate or the like, and a stirring shaft is provided horizontally in the two tanks, and a stirring shaft transmission device including a resin is connected to the stirring shaft. Is provided with a drive motor and a motor transmission, and the stirring shaft transmission is connected to the motor transmission via a transmission,
The effective use of the dead space at the bottom of the treatment tank allowed for a more compact garbage processor.

Furthermore, the stirring shaft transmission including resin is formed by a pulley for a toothed belt, the pulley is formed of a resin, and a plurality of cutout holes are radially provided on the side surface of the pulley. The weight and cost of the garbage disposer were reduced by using a metal toothed belt pulley that was used as a lightweight and low-cost resin molded product and by providing cutout holes to reduce the weight. In addition, the notch hole enables the abnormal rotation of the stirring shaft to be detected by a photo sensor or the like.

Further, the agitating shaft transmission including resin is formed by a half resin pulley for a toothed belt, and the pulley is divided into an outer peripheral portion and an inner peripheral portion by a tooth-shaped circle close to the outer periphery. The outer circumference is made by metal or non-metal drawing, etc., and the inner circumference is separately molded with resin, and the two are combined to form a pulley, or the outer circumference molded with metal or non-metal The inner peripheral part is formed integrally by outsert molding of the belt, and the inner peripheral part of the conventionally used pulley for a toothed belt made of metal is made into a lightweight and low-cost resin-processed product. We aimed to reduce the weight and cost of the waste disposal machine. Further, by forming the contact portion between the outer peripheral portion and the inner peripheral portion in a tooth shape, the shearing force at the contacting portion is dispersed, so that the total shearing force can be greatly increased.

Further, the transmission of the pulley for the toothed belt is constituted by a resin belt (timing belt),
By replacing the conventional steel roller chain with a lightweight and low-cost timing belt, the weight and cost of the garbage disposer were reduced. Also, vibration is reduced,
The noise is also reduced. In addition, oil for roller chains is not required, and oil contamination of the photo sensor for detecting abnormal rotation of the stirring shaft is eliminated, so that abnormal rotation of the stirring shaft can be accurately detected.

Further, the motor transmission of claim 1 is omitted, and the stirring shaft transmission is replaced by a pulley for a toothed belt with a built-in differential gear. The cost and noise of the garbage disposer were reduced by using a toothed belt pulley with a built-in differential gear at low cost and low noise. In addition, since the motor transmission can be omitted, maintenance and inspection of the food waste disposer is facilitated, and the weight and size are reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to an embodiment shown in the drawings.

FIG. 1 is a perspective view of a garbage disposer provided with the present invention, FIG. 2 is an explanatory view of a stirring shaft transmission (toothed belt pulley) provided in FIG. 1, and FIG. 3 is provided in FIG. FIG. 4 is an explanatory view of a toothed belt pulley different from before, FIG. 4 is an explanatory view of a transmission (timing belt) provided in FIG. 1, and FIG. It is explanatory drawing of a shaft transmission.

In FIG. 1, reference numeral 1 denotes a garbage processing machine, and the garbage processing machine 1 comprises a processing tank 2, a compost stocker 3, a deodorizing device 4, a driving device 5, a lid 6, and the like. Is separated by a partition plate 7 into a processing tank 2a and a processing tank 2b. A discharge path 10 for processed material and a deodorizing device 4 for evaporating gas are provided outside the side wall 9 of the processing tank 2b. 3 and a driving device 5 are provided below the processing tank 2. With this configuration, the lower part of the deodorizer 4 and the lower part of the processing tank 2 which are in a dead space can be used effectively, and the garbage disposal can be made more compact.

Next, the operation of the apparatus will be described. When the garbage is put into the treatment tank 2a, the drive unit 5 including a drive motor 28 and a motor transmission 29 formed by a combination of steel gears drives the agitation shaft transmission (teeth) through the transmission 11 formed of a steel chain. And the stirring shaft 13 having the stirring rod 8 in the processing tank 2 rotates, and the garbage is crushed and fermented and matured in the processing tank 2a, and the specific gravity becomes small and light, The partition plate 7 overflows into the treatment tank 2b in accordance with the rotation of the stirring rod 8. The aged garbage transferred to the processing tank 2b is further aged in this tank,
The specific gravity is also lowered, and overflows to the compost stocker 3 from a discharge path 10 provided in the side wall 9 of the processing tank 2b. The compost stocker 3 is composed of a drawer type container,
For example, it may be disposed of outside once a week.

The odor in the treatment tank 2 is deodorized from the exhaust port provided in the side wall 9 of the treatment tank 2b, passes through the filter 14 for preventing clogging, enters the deodorizing apparatus 4, and is deodorized by the blower 15 for deodorizing. Is exhausted into the atmosphere from the exhaust port.

Next, the stirring shaft transmission (toothed belt pulley) will be described with reference to FIG. Conventionally used (toothed belt pulley) is made of hardened steel, and is heavy in weight and expensive. The sprocket of the present invention has pulley teeth 22 on the outer periphery and is made of a hard, wear-resistant, lightweight and inexpensive resin such as Duracon or Delrin. Further, since a plurality of notches 21 are provided radially on the side surface of the pulley 12 for a toothed belt, the weight is further reduced. The shape of the notch hole 21 is circular, fan-shaped, or the like. The notch 21 also serves as a photosensor (not shown) provided for detecting abnormal rotation of the drive shaft. That is, photo sensors provided on both sides of the toothed belt pulley detect abnormal rotation of the drive shaft with a light beam passing through the notch hole 21, detect an abnormal load applied to the stirring rod, and stop the drive shaft. The breakage of the stirring rod is prevented beforehand.

Next, referring to FIG.
Will be described. If the garbage disposer has a large capacity, the agitation force is also large, and a large shearing force is applied to the pulley teeth 22. In this case, since the pulley teeth 22 are made of steel more durable than resin, the toothed belt pulley is divided into an outer peripheral portion 24 and an inner peripheral portion 25 by a tooth-shaped circle 23 close to the outer periphery. Then, the outer peripheral part 24 with the pulley teeth is made by metal or non-metal drawing, and the inner peripheral part 25 is made by resin processing, and the two are combined to form a pulley, or formed of metal or non-metal An inner peripheral portion is integrally formed on the outer peripheral portion by resin outsert molding. As described above, the pulley teeth 22 that require the strength and durability of the toothed belt pulley are made of metal, and the other parts are made of lightweight and low-cost resin, thereby reducing the weight of the toothed belt pulley. ,
Cost can be reduced. In addition, by forming the joint between the outer peripheral portion 24 and the inner peripheral portion 25 in a tooth shape, the shearing force due to the rotation can be uniformly received at the root of each tooth, so that both portions are not separated by an external force. .

Next, the transmission will be described with reference to FIG. Drive gear 26 directly connected to the shaft of drive device 5 and stirring shaft transmission
Conventionally, a roller chain was used as the transmission connecting the 12 and the transmission. The roller chain was made of steel, was heavy, and had high vibration and noise. In addition, since the roller chain uses lubricating oil, there is a problem that the oil adheres to the photosensor and greatly reduces the function of the photosensor. Furthermore, there was a problem that the feeding speed was slow. Therefore, in the present invention, the timing belt 11 made of a resin such as Duracon or Delrin, which is lightweight, has low vibration and noise, and does not affect the photo sensor, is used instead of the roller chain. As a result, it is possible to reduce the weight and noise of the transmission. Further, since the feed speed can be greatly increased as compared with the roller chain, it is possible to cope with the case where the motor speed change device is omitted and the feed speed is significantly increased as described later.

Next, the stirring shaft transmission 12 will be described with reference to FIG. The rotation of the stirring rod in the processing tank 2 is several times per minute, whereas the drive motor 28 rotates at 1500 revolutions per minute, so that the speed is reduced to about 1/75 by the motor transmission 29 and the stirring shaft transmission ( The speed is reduced to about 1/10 with the toothed belt pulley. Conventionally, a gear transmission is used for the motor transmission 29, and there are problems that it is expensive and that noise is large. Therefore, the use of the motor transmission 29 was stopped, and a stirring shaft transmission using a differential gear mechanism shown in FIG. 5 was adopted. In addition to the reduction of the toothed belt pulley (external gear) 12, the transmission
With the configuration of the fixed gear 30, the planetary gear 31, and the internal gear 32, the same speed reduction as that of the motor transmission 29 is obtained. 33 is a stirring shaft bearing, 34
Is a fixed gear bearing, 35 is an internal gear bearing, and 36 is a planetary gear bearing. 37 is the balance weight, the balance weight
37 is provided at a position symmetrical to the planetary gear 31 to maintain a dynamic balance when the planetary gear 31 rotates.

The rotation of the drive gear 26 is controlled by the timing belt 11.
To the pulley 12 for the toothed belt via the
(About 0), and further transmitted from the planetary gear 31 to the internal gear 32 via the fixed gear 30 from the toothed belt pulley 12 to achieve a reduction ratio substantially equal to that of the motor transmission 29 (about 1/75). obtain.

The reduction ratio of 1/75 by the differential gear mechanism will be described. The rotation speed of the internal gear 32 directly connected to the stirring shaft 13 is expressed by Na
And the rotation speed of the toothed belt pulley (external gear) 12 is Nb,
If the number of teeth of the internal gear 32 is Za and the number of teeth of the fixed gear 30 is Zc,
The rotational speed Na of the internal gear 32 is expressed as in the following equation (1).

[0030]

Na = (1−Zc / Za) Nb ‥‥‥‥ (Equation 1) Here, if Za = 75 and Zc = 74, Na = 1 / 75Nb, and the expected reduction ratio is obtained. be able to. It is also possible to use a motor for controlling the number of rotations as the drive motor 28 and reduce the number of rotations of the motor to a fraction of the current number. In this case, the diameters of the pulley 12 for the toothed belt and the internal gear 32 are small. Thus, the stirring shaft transmission 12 can be downsized. By employing the stirring shaft transmission, the motor transmission 29 can be omitted.

Since the gears used in the motor transmission 29 are smaller than the gears used in the agitating shaft transmission 12, a large number of gears are required to obtain a large speed reduction, making maintenance and inspection difficult and costly. However, the gears used in this agitating shaft transmission are only the fixed gear 30, the planetary gear 31, the internal gear 32 and the pulley (external gear) 12 for the toothed belt, making maintenance and inspection easy and low cost. be able to. Further, since the meshing of the gears is reduced, vibration and noise can be reduced.

Further, the toothed belt pulley 12 and each gear are made of steel, and are hard and lightweight Duracon having excellent wear resistance.
By using a resin such as Delrin, it is possible to reduce the weight.

[0033]

According to the second and third aspects of the present invention, the toothed belt pulley is light in weight and low in cost, so that the weight and cost of the garbage disposer can be reduced. The cutout holes on the side surfaces of the pulleys can be effectively used for photosensor detection for detecting abnormalities in the stirring shaft.

According to the structure of the fourth aspect, the transmission device is lightweight,
The low cost and low vibration make it possible to reduce the weight, cost and noise of the garbage disposer. In addition, the oil for the roller chain is not required, and the performance of the photo sensor is not degraded due to the oil, so that the abnormal rotation of the stirring shaft can be accurately detected.

According to the fifth aspect of the present invention, the motor transmission can be eliminated, the maintenance and inspection can be easily performed as a whole of the transmission, the weight can be reduced, the cost can be reduced, and the noise can be reduced.
