[0018]

FIG. 1 shows a first embodiment of the present invention.
This will be described with reference to FIG.

In FIG. 1, reference numeral 1 denotes an insulated container (in FIG. 1, as an example, a vacuum insulated container which is constituted by an inner wall and an outer wall and a space between the walls is evacuated); Container. A fixed blade 4 and a rotary blade 5 are provided in the garbage storage container 2 as means for crushing and stirring garbage. The fixed blade 4 is provided on the inner wall of the garbage storage container 2, and the rotary blade 5 is provided on the inner bottom of the garbage storage container 2 and is fixed to a rotating shaft 6 protruding from the bottom surface of the garbage storage container 2. . Above the garbage container 2, a heater 8 as a garbage heating means and a stirring fan 9 for uniformly sending the heat of the heater 8 into the garbage container 2 are provided. Reference numeral 10 denotes a motor for driving the stirring fan.

A condensing section 11 for condensing water vapor generated from garbage is disposed on the outer periphery of the heat insulating container 1.
A blower fan 12 for cooling the outer surface is installed outside the condenser 11. In this embodiment, the heat insulating container 1 and the garbage storage container 2 are installed in an inclined state, and they rotate integrally. Therefore, the rotation of the drive motor 14 is transmitted via the reduction gear 15 to the drive shaft 1.
The drive shaft 16 has a two-axis configuration, that is, an outer shaft 16a and an inner shaft 16b.
The outer shaft 16a is engaged with the heat insulating container 1 by a coupling 17a, and the heat insulating container 1 and the food waste container 2
To rotate. The inner shaft 16b is a coupling 17
b engages with the rotary shaft 6 to rotate the rotary blade 5.
The outer shaft 16a and the inner shaft 16b of the drive shaft 16 are configured to rotate in different directions.

A condensed water outflow pipe 1 is provided below the condensing section 11.
8. The exhaust pipe 19 is connected. At the end of the condensed water outflow pipe 18, a condensed water container 20 for storing condensed water is detachably provided. The exhaust pipe 19 is provided with a deodorizing device 21. Reference numeral 22 denotes a kitchen waste treatment machine main body, and reference numeral 23 denotes a lid that houses garbage heating means. The lid 23 is supported by a hinge 24, is openable and closable on the garbage disposer main body 22, sandwiches packing, the lid 23 and the garbage disposer main body 22 are fixed by a latch-type handle 25, and the garbage container 2 is sealed. State.

Next, the fixed blade 4 and the rotary blade 5 rotate in mutually opposite directions as shown in FIG. 3 so as to perform intermittent rotation in which stop and rotation are repeated, and to reverse the rotation direction at every rotation. Is controlled. The fixed blade 4 and the rotary blade 5 are connected to the drive shaft 1
6 has a two-axis configuration, and the outer shaft 16a and the inner shaft 1
6b are directions different from each other, the rotation directions of the rotary blade 5 and the garbage processing container 2 are different from each other. Therefore, the rotation directions of the rotary blade 5 and the fixed blade 4 provided on the garbage processing container 2 are opposite to each other. Direction. By doing so, the garbage put in the garbage storage container 2 is picked up by the fixed blade 4, stirred, and crushed between the fixed blade 4 and the rotary blade 5. In addition, since the fixed blade 4 and the rotary blade 5 rotate in directions opposite to each other, the relative speed between the fixed blade 4 and the rotary blade 5 increases, and the crushing ability of garbage can be increased.

When the fixed blade 4 and the rotary blade 5 are continuously rotated, starch-like garbage such as rice is strongly sticky.
It becomes rice cake-like and the inside becomes hard to dry. Therefore, by intermittently performing the rotation intermittently for a short time (for example, rotation for 5 seconds, pause for 60 seconds), starch-like garbage is prevented from becoming rice cake-like. Further, if the rotation is continued in only one direction, garbage tends to be clogged between the fixed blade 4 and the rotary blade 5, and the rotary blade 5 is easily locked. Therefore, the rotation direction of the rotary blade 5 is prevented from being locked by changing the rotation direction each time in the intermittent rotation.

A crushing blade 26 for crushing the bag for storing garbage is provided in a part of the rotary blade 5 in a vertical direction.
The rotary blade 5 is mainly for garbage crushing and stirring. The garbage is put in a garbage storage container 2 in a state of being put in a garbage storage bag (eg, a polyethylene bag), and is crushed and dried. In this case, since the rotary blade 5 rotates, the crushing blade 26 provided on the rotary blade 5 also rotates at the bottom of the garbage storage bag to crush the bag. Then, garbage in the bag spills out of the bag, and is crushed by the tip of the rotary blade 5 and the fixed blade 4. Thus, the garbage can be put into the garbage storage container 2 in a state of being put in the garbage storage bag, thereby improving the usability of the kitchen waste disposal machine.

The rotary blade 5 is configured to be detachably engaged with the rotary shaft 6. That is, as shown in FIG. 2, the tip of the rotating shaft 6 has a substantially D-shaped cross section, and a thin groove 27 is provided in a part thereof. Similarly, a hole having a substantially D-shaped cross section is provided in the center of the rotary blade 6, and a projection 29 urged by a spring 28 protrudes into the hole. When the rotary blade 5 is inserted into the tip of the rotary shaft 6, the protrusion 29 fits into the groove 27,
When the rotary blade 5 and the rotary shaft 6 are engaged with each other and the rotary blade 5 is pulled by hand, the rotary blade 5 can be easily removed. Therefore, when the inside of the garbage storage container 2 becomes dirty or garbage burns on the rotary blade 5, the rotary blade 5 can be removed and the garbage storage container 2 and the rotary blade 5 can be washed, and cleaning can be performed. It is configured to be easy to operate.

The surface of the rotary blade 5 is made of plastics. In other words, when the rotary blade 5 is made of metal, the other surface is covered with plastics (broken line portion in FIG. 2) except for the blade portion at the tip.
The rotary blade 5 may be entirely made of plastics. Since plastics has higher non-adhesiveness than metal, this configuration makes it possible for garbage to hardly seize to the rotary blade 5 during crushing and drying, and to easily wipe off garbage even if it adheres. Easier to do.

If the fixed blade 4 has the same configuration as the rotary blade 5, the burning of garbage can be more effectively eliminated.

The operation of the kitchen garbage disposer configured as described above will be described. The garbage put into the garbage storage container 2 is pulverized intermittently in opposite directions and between the rotating blade 5 and the fixed blade 4 whose rotation directions are reversed. At the same time, the garbage is heated by the heater 8 and uniformly diffused into the garbage container 2 by the stirring fan 9. Further, the garbage storage container 2 rotates in an inclined state. At this time, the fixed blades 4 provided on the inner wall of the garbage storage container 2 scoop up the garbage, so that the crushed garbage is stirred. Steam containing odor components is generated from the garbage, and flows into the condensing section 11 outside the heat insulating container 1 from the opening of the garbage storage container 2.

The steam is condensed by being cooled by the blower fan 12 in the condensing section 11, and the condensed water outflow pipe 18
And collects in the condensed water container 20. On the other hand, the water vapor containing the odor component that has not been completely condensed is guided from the exhaust pipe 19 to the deodorization device 21, where the odor component is purified. Although the crushed and dried garbage remains in the garbage storage container 2, the bulk is reduced and the water activity is reduced by drying. No dripping or mold formation. Therefore, the garbage can be put on the dried garbage one after another until the garbage storage container 2 is full, and the garbage can be dried. Then, the dried garbage remaining in the garbage storage container 2 and the condensed water accumulated in the condensed water container 20 are periodically collected and discarded.

In this embodiment, the garbage storage container 2 is tilted and rotated in order to enhance the garbage stirring effect. It is good also as a structure which fixed container 2 vertically.

Hereinafter, a second embodiment in which the food waste container is fixed vertically will be described. This embodiment will be described with reference to FIGS. In FIG. 4, reference numeral 31 denotes a heat insulating container, which forms an air layer as a heat insulating layer between the double walls. 32

Reference numeral 34 denotes a rotating blade that is arranged in two stages in the upper and lower direction, and one end of each blade 34a is substantially parallel to the fixed blade 33, and the other 34b is a rotating blade that rotates while crossing the fixed blade 33 substantially perpendicularly. The rotation of the motor 35 is transmitted to the attached rotating shaft 35a via a belt 36. The fixed blade 33 and the rotary blade 34 constitute crushing and stirring means for crushing and stirring garbage inside the garbage storage container 32.

Numeral 38 denotes a condensing section arranged on the outer periphery of the heat insulating container 31, and a cooling fan 39 is installed outside the condensing section.
Reference numeral 40 denotes a condensed water collecting container for collecting and storing the condensed water flowing out of the condenser 38. Reference numeral 41 denotes a lid which can be opened and closed on the upper part of the kitchen waste processing machine main body.
Sealed with. Reference numeral 42 denotes a stirring fan composed of a centrifugal fan for stirring air in the garbage storage container 32, the rotating surface of which is provided substantially parallel to the lower surface 47 of the lid 41, and protrudes from the upper opening of the garbage storage container 42. Reference numeral 43 denotes a heater that uses the stirring air from the stirring fan 42 as hot air, and is provided around the stirring fan 42. And the stirring fan 42
And a heater 43 for drying the garbage. In addition, the heat insulation container 31 and the garbage storage container 32
And the lower surface 47 of the lid 41 are arranged with a gap.

Reference numeral 44 denotes a hood provided on the lower surface 47 of the lid 41 for guiding the hot air discharged from the stirring fan 42 into the garbage container 32. 45 is a stirring fan 42
, And is installed in the lid 41 together with the cover 46 and the heat insulating material 60. Shaft 49 of drive motor 45
As shown in FIG. 7, a bearing 57 penetrating the lower surface 47 of the lid 41 and covering the penetrating portion 48 and having a grease reservoir 57a is slidably provided. The bearing 57 is urged toward the lower surface 47 of the lid 41 by a spring 58. The shaft 49 is provided with a self-cooling fan 59.

As shown in FIG. 4, the condensing section 38 and the condensed water collecting vessel 40 are connected by a hose 50.
0 is branched and connected to the deodorizing device 21. In the condensed water collecting container 40, a detecting device 53 composed of a float switch for detecting that the condensed water is full is provided. In this embodiment, a float 55 having a magnet 54 built therein and a reed switch 56 are provided. It is composed. Further, the condensed water collecting container 40 is arranged close to the deodorizing device 51 which becomes relatively hot when energized, so that the heat acts on the detecting device 53. Further, a temperature sensor 52 is provided near the heater 43 and in the passage of the exhaust air from the stirring fan 42 to control the temperature of the heater 43.

The operation of the kitchen garbage disposer configured as described above will be described. The garbage put into the garbage container 32 is stirred by the rotary blade 34 and crushed by the rotary blade 34 and the fixed blade 33. Stirring fan 42
The hot air from the heater 43 circulates in the space formed by the lower surface 47 of the lid 41, the hood 44, and the garbage container 32, and heats the garbage while stirring the air in the space. Steam is generated from the heated garbage and overflows into the condensing section 38 from a gap between the upper end of the garbage storage container 32 and the lower surface 47 of the lid 41. Due to the function of the heat insulating container 31, the temperature of the condensing portion 38 is lower than that of the inside of the garbage storage container 32,
The water vapor is condensed into water and collected in a condensed water collecting container 40. On the other hand, the water vapor containing the odor component that has not been completely condensed is guided from the branch hose to the deodorization device 51, where the odor component is purified and discharged to the outside. Although the crushed and dried garbage remains in the garbage storage container 32, the garbage is reduced in volume and dried, and the water activity is reduced. There is no.

Here, when the condensed water collecting container 40 is full, the detecting device 53 operates, and control is performed so that the condensed water cannot be operated in the next operation unless the condensed water is discarded. Since the capacity of the condensed water collecting container 40 has a margin for one treatment of the condensed water, at the time when the detecting device 53 operates, even if the detecting device 53 is operated during the operation, the round is processed to the end. However, in the next operation, the operation cannot be performed unless the condensed water is discarded, so that the water does not overflow from the condensed water collection container 40. If the outside air temperature decreases and the condensed water freezes and the detection device 53 does not move, water may overflow. However, the deodorization device 5 which is a heat source is located near the detection device 53.
Since the device 1 is provided, the freezing of the condensed water is released by the heat of the deodorizing device 51 during operation, and the detecting device 53 operates normally and the water does not overflow.

Next, the operation of the stirring fan 42 will be described with reference to FIG. The wind discharged from the stirring fan 42 has a flow velocity V in the rotation direction component of the stirring fan 42 as shown in FIG. 5 and is fed into the garbage container 32 while being guided by the hood 44, and Is heated and then sucked into the stirring fan 42 from the center of the stirring fan 42 again. Therefore, when the hot air contains steam in the middle of drying, the temperature sensor 52 provided near the heater 43 because the hot air rotates at high speed around the outer periphery of the heater 43 is more affected by the steam than the radiant heat of the heater 43, That is, the temperature in the garbage storage container 32 is measured. Therefore, the heater 43 is frequently set so that the temperature inside the garbage storage container 32 becomes the drying temperature.
Can be entered to speed up drying.

When the drying proceeds and the steam in the hot air decreases, the temperature sensor 52 becomes more susceptible to the radiation heat of the heater 43 and measures the temperature of the heater 43 itself. Therefore, when steam decreases and the temperature of the heater 43 rises rapidly, the temperature sensor 52
Since the temperature of the heater 3 itself is measured, it is possible to prevent the heater 43 from rising excessively and to save the heater power consumption.

Next, the crushing and stirring of garbage will be described with reference to FIG. The rotary blade 34 is formed by two blades arranged in two stages, upper and lower.
As shown in FIG. 6A, the fixed blade 33 intersects substantially parallel to the fixed blade 33, and the tip of the other blade 34b is fixed to the fixed blade 33 as shown in FIG.
And intersect approximately vertically. Therefore, the garbage can be efficiently pulverized due to the different crossing angles, and when the crossing angle is one direction, the garbage is more likely to be entangled with the fixed blade 33, but the tangling is changed by changing the crossing angle. Can be prevented. In addition, since the rotary blades are arranged in two stages, the garbage moves not only in the rotating direction but also in the up and down direction, so that the stirring is performed efficiently and the drying of the garbage is promoted. In addition, since the stirring performance of the garbage is enhanced, the garbage can be effectively stirred without inclining the garbage storage container.

Next, the relationship between the stirring means 42, the drive motor 45, and the lid 41 will be described with reference to FIG. The bearing 57 slidably provided on the shaft 49 of the drive motor 45 is provided with a grease reservoir 57a to cover and seal the gap between the shaft 49 of the drive motor 45 and the through portion 48. Can be set with a margin, and it is possible to cope with the fluctuation of the gap due to vibration and thermal expansion. Further, the bearing 57 and the spring 58 are air-cooled by the self-cooling fan 59 so that the stirring fan 4
2 to radiate the heat transmitted to the drive motor 45 to reduce the temperature rise of the drive motor 45.

As described above, according to the first aspect of the present invention, the garbage put in the garbage storage container is heated and dried by the garbage heating means while being crushed and agitated. The water vapor containing the odor component generated from the water is led to the deodorizing device, where the odor component is purified. Although the crushed and dried garbage remains in the garbage storage container, the bulk is reduced and the water activity is reduced by drying. No mold will develop. Therefore, the garbage can be put on the dried garbage and dried until the garbage storage container becomes full. In addition, since the garbage is pulverized, heat can be easily transferred into the garbage, so that the drying speed can be increased and the drying processing time can be reduced.

According to the second aspect of the present invention, a fixed blade provided on the inner wall of the garbage storage container and a rotary blade provided on the inner bottom of the garbage storage container are employed as the crushing and stirring means. The garbage is pulverized between the garbage and the rotary blade, and the garbage can be efficiently crushed, stirred, and dried.

According to the third aspect of the present invention, since the rotary blades are arranged vertically in two stages, the garbage moves not only in the rotating direction but also in the vertical direction, so that the stirring is efficiently performed. The drying of garbage is promoted.

According to the fourth aspect of the present invention, since the crossing angle between the fixed blade and the rotary blade is made different, the garbage can be efficiently pulverized, and the crossing angle is one direction. In this case, garbage is likely to be entangled with the fixed blade, but entanglement can be prevented by changing the intersection angle.

According to the fifth aspect of the present invention, the garbage is thrown into the garbage storage container by providing a crushing blade for crushing the garbage storage bag at a part of the rotary blade. At this time, since the garbage can be stored in the garbage storage bag, the garbage can be easily handled.
