Description

The present invention relates to a garbage processing machine for processing garbage generated in a kitchen or the like.

(4) A conventional garbage processing machine of a drying system will be described with reference to FIG. An upper heating means 2 for heating the garbage storage container 1 for storing garbage, a blower fan 3, a stirring means 4, and a lid 5 of the garbage storage container 1 are provided, and the garbage storage container 1 evaporates. A deodorizing device 6 for removing odors from the steam to be produced and a suction fan 7 on the exhaust side of the deodorizing device 6 are provided to forcibly discharge the steam after the deodorizing. Reference numeral 8 denotes a packing for tightly closing the lid 5 and the garbage storage container 1.

に お い て In the above configuration, the garbage in the garbage storage container 1 is heated by the upper heating means 2 and the blower fan 3. The steam generated from the garbage is discharged by the suction fan 7 after the odor is removed by the chemical reaction in the deodorizing device 6 or in the deodorizing device 6. At the same time, the garbage is dried while being stirred and pulverized by the stirring means 4, and after the drying is completed, the weight is reduced and divided.

Here, the garbage storage container 1 is formed of resin so that heated garbage does not stick to the surface, but the whole is made thick for reasons such as securing strength when dropped. Therefore, the heat capacity is large, and the temperature of the food waste storage container 1 is hard to rise, so that the food waste is hardly heated by radiation and the drying time tends to be extended. In addition, resin is less likely to stick than metal, but when drying proceeds, moisture decreases, and when the surface temperature of the garbage storage container 1 increases, garbage containing a large amount of sugar has high adhesiveness, and thus may stick. The sides were easily peeled off by the weight of the garbage, but the bottom was susceptible to spillage and was particularly susceptible to sticking. Further, in the case of resin, the temperature change due to heat is large, the height dimension changes, and the airtightness of the packing 8 for sealing the lid 5 and the garbage storage container 1 may become unstable. .

The present invention has been made to solve the above problems, and an object of the present invention is to prevent a garbage storage container formed of resin from being changed in size by heat and to improve the airtightness between the garbage storage container and a lid.

The present invention to achieve the above object is to mix glass fibers and the like into the material of the garbage storage container and form the glass fibers so that the orientation of the glass fibers on the side is aligned in the height direction. Dimensional change due to thermal shrinkage can be suppressed, the airtightness of the packing that makes the lid and the garbage storage container airtight can be stabilized, and steam and odor can be prevented from leaking.

According to the present invention, glass garbage and the like are blended into the material of the garbage storage container, and the side surfaces are formed so that the orientation of the glass fibers is aligned in the height direction. By suppressing this, steam and odor can be prevented from leaking, and a user-friendly garbage disposal can be provided.

In the invention according to claim 1 of the present invention, the material of the garbage storage container is mixed with glass fiber and the like, and the side glass fibers are formed so that the orientation of the glass fibers is aligned in the height direction. The dimensional change due to thermal shrinkage in the direction can be suppressed, the airtightness of the packing that makes the lid and the garbage storage container airtight can be stabilized, and steam and odor can be prevented from leaking.

(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2, reference numeral 12 denotes a garbage storage container for storing garbage. A fixed blade 13 is provided on an inner wall of the garbage storage container 12. Reference numeral 14 denotes a rotary blade which rotates while intersecting with the fixed blade 13, and is connected to the center shaft 16. The center shaft 16 is driven by the rotation motor 15. Reference numeral 17 denotes a lid, and a packing 20 attached to the lid side is pressed against the garbage storage container 12 in order to maintain airtightness between the lid 17 and the garbage storage container 12. Heating means including a heater 18 and a blower fan 19 is provided below the lid 17 and is covered with a protective cover 45 having a plurality of openings 46. Reference numeral 21 denotes a discharge port provided inside the lid 17, and reference numeral 22 denotes an upper pipe connected to the discharge port 21. 23 is a drying motor. A suction unit including a suction fan 27 and a suction motor 28 is provided on the exhaust side of the deodorizing device 25.

The deodorizing device 25 is provided with a catalyst 30 coated with a member that chemically decomposes an odor and a catalyst heater 31 for heating the catalyst 30 to promote a chemical reaction, and is housed in a metal case 32 and heated. The water vapor containing the odor generated from the garbage is discharged to the outside after the odor is removed by the deodorizing device 25.

In the above configuration, the air heated by the heater 18 is sent into the garbage container 12 through the opening 46 by the blower fan 19 to heat the garbage. The air in the garbage storage container 12 travels through the opening 46 of the protective cover 45, and the temperature of the air in the garbage storage container is uniformly heated at about 130 ° C. Steam generated from the heated garbage is discharged from a discharge port 21 provided inside the lid 17, passes through an upper pipe 22 connected to the discharge port 21, and passes through an upper pipe 22 and a connection packing 24 to a deodorizer 25. It passes through the connected lower pipe 26 and reaches the deodorizer 25. After the odor is removed by a chemical reaction in the deodorizing device 25, the odor is discharged to the outside by the suction fan 27. At the same time, the garbage is dried while being stirred and pulverized by the rotary blade 14 rotating while intersecting with the fixed blade 13, and after the drying is completed, the weight is reduced and the food is divided.

Here, the garbage storage container 12 is made of a high heat-resistant resin having a heat resistance of about 150 ° C., and conventionally, the entire garbage storage container 12 has a uniform thickness of about 3 mm in order to ensure strength when the garbage storage container 12 falls. However, in the present invention, the bottom surface 40 is formed thick (about 3 mm) and the side surface 41 is formed thin (about 2 mm). The inside of the garbage container 12 is heated to about 130 ° C. by the heating means including the heater 18 and the blowing fan 19, and the garbage inside is also heated. At this time, the side surface of the garbage storage container 12 close to the heating means including the heater 18 and the blower fan 19 is formed to be thinner than the conventional one, so that the heat capacity of the side surface is smaller than the conventional one and the temperature is easily raised. Therefore, the garbage can be heated more quickly by the radiant heat because the garbage can be heated more quickly by the radiant heat, and the temperature of the garbage that touches the garbage storage container 12 at each stirring becomes higher than before. Since the side surface 41 is touched, more heating can be performed.

Therefore, the garbage can be dried in a short time with higher heating efficiency than in the past. Although the side surface 41 is thinner than the conventional product, the bottom surface 40, which is a surface to receive an impact when the garbage storage container 12 is placed or when the garbage storage container 12 is dropped by mistake, is made thicker to cause the same level of cracking as the conventional one. Since no strength is secured, it is possible to maintain strength that does not hinder practical use.

In the present embodiment, the thickness of the side surface is made uniform and thin. Needless to say, the above-described effect can be obtained even when the thickness is gradually changed to secure the strength of the bottom portion. In that case, since the change in the wall thickness is smooth, the moldability of the garbage storage container is improved. Of course, the thickness of the bottom surface may be gradually changed. In short, a thin portion is provided to reduce the heat capacity, and the bottom portion or the lower portion of the side surface may have a thick portion to maintain necessary strength. There is no particular regulation on how to change the thickness.

Further, the material of the garbage container 12 employs a high heat-resistant resin, but this material contains 30 to 40% of glass fiber. The glass fiber having a length of 0.1 to 3 mm is provided along the height direction of the side surface 41 in consideration of providing a gas vent at the upper end of the side surface 41 so that the flow flows from the bottom to the top over the entire circumference. Are oriented in parallel. Since glass fibers undergo less dimensional change due to heat than resin, the garbage storage container 12 has less heat shrinkage in the height direction due to the glass fibers arranged in the height direction, and is dimensionally stable. Therefore, there is little change in the pressure allowance between the garbage storage container 12 and the packing 20, and the airtightness is stably ensured, so that odor leakage and the like can be prevented.

Further, on the bottom surface, when the garbage container 12 is formed, the length of the gate is set to 0.1 to 3 mm by taking into consideration the fact that the position of the gate is positioned at the center so that the resin flow on the bottom surface 40 flows from the center of the bottom surface toward the outer periphery. Are all radially arranged on the bottom surface 40 in the radial direction. Therefore, since the glass fibers that are made of resin but have little dimensional change due to heat are arranged in the radial direction, the food waste container 12 has little thermal shrinkage in the radial direction. Conventionally, when the garbage dries, the water content decreases, and the surface temperature of the garbage storage container 12 increases, the garbage containing a large amount of sugar has a high viscosity, so that the garbage sometimes sticks. Even if the drying progresses and the water content decreases and the surface temperature of the garbage storage container 12 increases, the dimensional change of the bottom surface 40 of the garbage storage container 12 is smaller than that of the resin. Since the garbage shrinks more than the garbage storage container 12, when the dry garbage shrinks, the garbage naturally comes off from the garbage storage container 12.

(Embodiment 2)
Next, a second embodiment of the present invention will be described with reference to FIG. The configuration of the main body is the same as that of the first embodiment, and the description is omitted. In FIG. 3, the second garbage storage container 35 is made of a heat-resistant resin that is thin (about 2 mm) and does not contain glass fiber or the like, and has a plate 36 formed of a resin containing glass fiber on the inside of the bottom surface. Is molded integrally. The bottom is curved in a gentle mountain shape.

(4) In the above configuration, the side surface is made thin, and the bottom surface has the plate, so that the strength of the bottom surface is increased and the dimensional change due to temperature is small, so that the same effects as in the first embodiment can be obtained. Further, since the material of the plate 36 containing the glass fiber is small, even if it is made of a special material, the cost does not need to be so high. Therefore, the heat shrinkage is suppressed by using a material having a small shrinkage. The refuse that has adhered to the bottom surface is made of an organic material and shrinks in size when dried more than the resin. Further, since the bottom surface is curved, a difference in shape between the bottom surface of the garbage storage container 35 and the dried refuse caused by a difference in shrinkage between the plate 36 and the dried refuse further facilitates peeling, thereby preventing sticking.

In this embodiment, the plate 36 is provided integrally with the second garbage storage container 35, but the plate 36 is not provided, and the bottom surface of the second garbage storage container 35 can be simply dried by drying. It goes without saying that peeling occurs due to the difference in shape between the garbage and the second garbage storage container 35 at the time of shrinkage, and the effect of preventing sticking is obtained. The shape to be curved is not limited to being curved upward, but may be downward. In short, the same effect can be obtained if a difference in shape due to a difference in shrinkage occurs between the shrinking dry waste and the bottom of the garbage storage container. Obtainable.

As described above, the garbage disposer according to the present invention can suppress dimensional change due to heat shrinkage in the height direction of the garbage storage container, so that garbage can be heated regardless of whether it is for home use or business use. It is useful for all garbage disposers having a heating means.
