Description

  The present invention relates to a control system for a garbage processing machine for reducing the amount of garbage generated in a kitchen of a home or a restaurant.

  A conventional garbage disposal machine will be described with reference to FIG.

  When the garbage is put into the storage container 101 and the operation of the garbage processing machine main body 120 is started, the drying heater 107 is energized, hot air is blown to the garbage by the drying fan 108, and the drying process is started. During the drying process, the agitation means 105 for agitating the garbage provided inside the storage container 101 is operated so that the garbage in the storage container 101 can be heated evenly.

  When the drying of the garbage starts, water vapor is generated in the storage container 101, the water vapor passing through the exhaust passage 110 increases, and the temperature of the water vapor passing through the exhaust passage 110 rises.

When the garbage is further dried, the amount of water vapor in the storage container 1 is reduced, and when the temperature of the water vapor passing through the exhaust passage 110 becomes equal to or lower than a predetermined temperature, the drying heater 107 is energized as having been dried. The operation was stopped. Moreover, the dried processed material after a garbage drying process can be utilized as a fertilizer (for example, refer patent document 1).
JP-A-9-289406

  In recent years, development of biodegradable polymer compounds taking into consideration environmental issues such as global warming has progressed, and containers, bags, and the like have been molded from biodegradable polymer compounds. Also, even if a bag molded with a biodegradable polymer compound is heat-treated with garbage, there is no residue left behind when heat-treated with a polyethylene bag, etc., and the garbage is dried. Biorecycling is also possible when the later dried product is used as fertilizer. For this reason, a garbage processing machine that can directly process the whole garbage enclosed in a bag formed from a biodegradable polymer compound, such as a kitchen garbage drain, etc., is useful. Come.

  However, the conventional garbage processing machine does not have a structure that assumes that the garbage is enclosed in a bag or the like and dried, so when the garbage is agitated, the garbage-filled bag is broken to remove the garbage in the bag. Although it becomes possible to heat evenly in the storage container and the drying process is possible, there is a problem that it takes time to heat and dry the garbage.

  The present invention solves the above-described problem, and enables the garbage enclosed in the bag formed of the biodegradable polymer compound to be heated evenly in the storage container earlier, and the garbage is heated and dried more quickly. It is an object of the present invention to provide a garbage processing machine with a short processing time.

  In order to solve the above-described conventional problems, the garbage processing machine of the present invention includes a storage container that can store garbage in a state of being enclosed in a bag formed of a biodegradable polymer compound, Drying and heating means for drying and reducing the amount of waste by heating the garbage, and stirring means for stirring the garbage thrown into the interior of the storage container, a convex portion is provided on the bottom of the storage container toward the inside of the storage container, A garbage processing machine provided with a convex heating means for heating the convex shaped part in the vicinity of the lower part of the convex shaped part and heating and melting a part of the bag body in contact with the convex shaped part It was. Thereby, when the garbage enclosed in the bag is put in and the operation is started, the heating means for heating the convex portion provided on the bottom surface of the storage container is operated and is in contact with the convex portion. The bag body is melted, and the garbage enclosed in the bag body is heated evenly in the storage container earlier with the operation of the stirring means. Therefore, it is possible to heat and dry the garbage faster.

  The present invention operates a heating means for heating the convex portion provided on the bottom surface of the container, and the bag formed by the biodegradable polymer compound in contact with the convex portion is melted and stirred. With the operation of the means, the garbage enclosed in the bag body is heated evenly in the storage container earlier, and the garbage enclosed in the bag body is heated and dried more quickly, so that the garbage processing machine with a short processing time is used. Is intended to provide.

  The first invention is a storage container that can store garbage enclosed in a bag formed of a biodegradable polymer compound, and drying that reduces the weight by heating the garbage in the storage container. A heating means and a stirring means for stirring the garbage thrown into the storage container; a convex shape portion is provided on the bottom surface of the storage container toward the inside of the storage container; and the convex shape portion is provided near the lower portion of the convex shape portion. And a convex portion heating means for heating and melting a part of the bag body in contact with the convex shape portion is provided. Thus, when the garbage enclosed in the bag formed of the biodegradable polymer compound is put into the storage container and the operation is started, heating for heating the convex portion provided on the bottom surface of the storage container The means is operated, the bag body in contact with the convex portion is melted, and the garbage enclosed in the bag body is more evenly dispersed in the storage container and heated with the operation of the stirring means. Therefore, the garbage enclosed in the bag can be heated and dried earlier. Therefore, it is possible to provide a garbage processing machine with a short processing time by heating and drying the garbage enclosed in the bag formed of the biodegradable polymer compound more quickly.

  According to a second aspect of the present invention, in order to agitate the garbage put into the storage container to the bottom of the storage container, the agitation means has a stirring means bottom portion provided so as to be close to the bottom surface of the storage container. In this case, the orbit of the bottom of the stirring means avoids the convex shape. Since the garbage at the bottom of the storage container can be stirred by bringing the bottom of the stirring means close to the bottom of the storage container and the garbage in the storage container can be stirred more evenly, the bottom of the storage container and the stirring means can be It is necessary to provide more proximity portions with the bottom. Since the convex shape portion is provided at the bottom of the storage container, the stirring means makes the orbit of the bottom of the stirring means avoid the convex shape portion when stirring the garbage so that the bottom of the stirring means is closer to the bottom of the storage container. The garbage in the storage container can be stirred and heated and dried more evenly. Therefore, it is possible to provide a garbage processing machine with a short processing time by heating and drying the garbage enclosed in the bag formed of the biodegradable polymer compound more quickly.

  According to a third aspect of the present invention, a part of the bag body is heated and melted, and the garbage enclosed in the bag body formed of the biodegradable polymer compound becomes uniform in the storage container. An operation time measuring means for measuring the drying operation time is provided to discriminate the time until promoted, and the control device heats the convex shape for a predetermined time from the start of operation according to the information of the operation time measuring means. The garbage processing machine operates the convex heating means at a first energization rate and operates the convex heating means at a second energization rate lower than the first energization rate after a predetermined time has elapsed. At the stage where the bag body is heated and melted immediately after the start of operation, the convex portion heating means is set at a high energization rate so that the garbage enclosed in the bag body is quickly heated and dried in the storage container. Make it work. However, if the vicinity of the bottom of the storage container is heated at a high temperature at a stage where the drying of the raw garbage is progressing to some extent, the garbage being processed sticks to the convex portion in the storage container and the usability deteriorates. This is particularly true when garbage containing a large amount of sugar is introduced. Therefore, the energization rate of the convex heating means is lowered after a predetermined time has elapsed since the start of operation. Accordingly, it is possible to provide a garbage disposal machine in which the garbage enclosed in the bag formed of the biodegradable polymer compound is heated and dried more quickly so that the treatment time is short and the usability is improved.

  According to a fourth aspect of the present invention, based on the drying sensor that directly or indirectly detects the temperature in the storage container and the output of the drying sensor, the temperature in or near the storage container is maintained at a predetermined set temperature. A control device for controlling the drying and heating means is provided. A part of the bag body is heated and melted, and the garbage enclosed in the bag body formed of the biodegradable polymer compound becomes even in the storage container. The time until the heat drying of the waste is promoted is determined by an increase in the output of the drying sensor, and when the output of the drying sensor is equal to or less than a predetermined value, the control device first heats the convex shape. This is a garbage disposal machine that operates at a second energization rate when the convex heating means is operated at an energization rate of and the output of the drying sensor exceeds a predetermined value. Part of the bag is heated and melted, and the garbage enclosed in the bag formed of the biodegradable polymer compound becomes even in the storage container, and the temperature of the garbage rises as drying of the garbage proceeds. As the temperature rises, the temperature in the storage container rises and the output value of the drying sensor also rises. Therefore, the dry state of the garbage in the storage container can be accurately estimated from the output value of the drying sensor. Therefore, when the output of the drying sensor is equal to or greater than the predetermined value, the energization rate of the convex heating means is reduced, and the convexity in the storage container is reduced. Garbage treatment that prevents garbage from sticking to the shape, heats and dries the garbage enclosed in a bag molded with a biodegradable polymer compound, shortens the processing time, and improves usability Machine can be provided.

  5th invention provides the vapor | steam detection means which detects the water vapor | steam which generate | occur | produces from garbage, a part of said bag body is heat-melted, and the garbage enclosed with the bag body shape | molded with the biodegradable polymer compound Has a control device that discriminates the time until heating and drying of food waste is promoted by the output of the steam detection means, and the output of the steam detection means is below a predetermined value, The control device is a garbage processing machine that operates the convex heating means at a first energization rate so as to heat the convex shape, and operates at the second energization rate when the output of the steam detection means exceeds a predetermined value. A part of the bag is heated and melted, and the garbage enclosed in the bag formed by the biodegradable polymer compound becomes even in the storage container. As a result, the output value of the steam detection means increases. Therefore, the dry state of the garbage in the storage container can be directly measured by the output value of the steam detection means. Therefore, when the output of the steam detection means is greater than or equal to a predetermined value, the energization rate of the convex heating means is lowered to reliably prevent the garbage from sticking to the convex shape part in the storage container, and the biodegradable polymer compound Thus, it is possible to provide a garbage disposal machine in which the garbage enclosed in the bag formed by the above method is heated and dried more quickly, the treatment time is short, and the usability is improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
The first embodiment of the present invention will be described below with reference to FIGS.

  The garbage processing machine main body 20 is provided with a cylindrical storage container 1 for storing garbage, and a lid 2 that covers the storage container 1 so as to be freely opened and closed. Inside the storage container 1, stirring means 5 for stirring the waste is disposed, and the stirring means 5 is driven by a stirring motor 6. A circular convex portion 3 having a shape similar to the outer shape of the storage container 1 is provided on the bottom surface of the storage container 1. Further, an R shape is provided at the base of the convex portion 3 as shown in FIG. A convex portion heating means 4 for heating the convex portion 3 is disposed below the convex portion 3. Further, as shown in FIG. 2, the vertical cross-sectional shape of the stirring means 5 is such that the bottom portion is close to the bottom surface of the storage container 1 while avoiding the convex portion 3. In the upper part of the storage container 1, a drying sensor 13 that is a temperature detection means for detecting the temperature in the storage container 1, a drying heater 7 that heats the garbage, and the garbage heated while stirring the air heated by the drying heater 7 A drying fan 8 for spraying is provided.

  The gas containing water vapor generated from the garbage is deodorized by the oxidation catalyst 9 through the exhaust passage 10 connecting the storage container 1 and the oxidation catalyst 9 for deodorizing the odor. The discharge passage 10 through which the gas that has passed through the oxidation catalyst 9 passes is connected to a suction discharge fan 12 for sucking water vapor generated from the garbage and discharging it to the outside. The exhaust exhausted by the suction exhaust fan 12 is configured to be exhausted from the exhaust port 11 provided in the garbage processing machine body 20.

  A part of the exhaust passage 10 is provided with a steam detection means 14 that directly or indirectly detects the temperature of a gas containing water vapor generated from garbage passing through the exhaust passage 10.

  The operation of the above configuration will be described. When the user puts the garbage 15 sealed in a bag formed of a biodegradable polymer compound into the storage container 1 and starts operation, the drying heater 7 is energized, and the drying fan 8 generates hot air. It is sprayed on the garbage and the heat drying process starts. At this time, the oxidation catalyst 9 is also heated to a temperature that exhibits the deodorizing ability. At the same time, the convex heating means 4 disposed below the convex portion 3 is energized at the first energization rate by the control device 16. The bag 15 molded from the biodegradable polymer compound by heating the convex portion 3 is melted and the garbage 15 enclosed in the bag molded from the biodegradable polymer compound by stirring by the stirring means 5 is: The storage container 1 is dispersed and heated earlier and more uniformly.

  The heating temperature of the garbage by the drying heater 7 and the drying fan 8 is always detected by the drying sensor 13, and is controlled by a control circuit (not shown) so that the food is heated and dried so that the temperature becomes constant.

  Next, when the predetermined time T elapses from the start of operation and the drying of the garbage progresses in earnest, the output of the drying sensor 13 increases beyond the predetermined value A as the temperature in the storage container 1 rises. Further, since the temperature in the storage container 1 rises, a large amount of raw water vapor is generated, and the detection value detected by the steam detection means 14 in the exhaust passage 10 becomes higher than the predetermined value B.

  At this time, since the garbage in the storage container 1 is soft and gelled, when the convex portion 3 provided on the bottom surface of the storage container 1 is heated at a high temperature, the garbage sticks to the bottom surface of the storage container 1. It often happens. Especially in garbage with a lot of carbohydrates, sticking becomes remarkable and usability deteriorates. Therefore, after a predetermined time T has elapsed from the start of operation, or when the output of the drying sensor 13 exceeds the predetermined value A, or when the output of the steam detection means 14 exceeds the predetermined value B, the control device 16 detects the convex portion heating means 4. Is switched to a second energization rate lower than the first energization rate.

  Further, when the garbage is further dried, the amount of water vapor in the storage container 1 is reduced, and when the water vapor passing through the exhaust passage 10 is less than or equal to the predetermined value C, the drying is completed. The energization of the drying heater 7 is stopped, the energization of the convex heating means 4 is also stopped, and the operation is stopped when the temperature in the storage container 1 becomes a predetermined value or less.

  Moreover, the dry treatment thing after the garbage drying process containing the bag shape | molded with the heat-processed biodegradable polymer compound can be utilized as a fertilizer.

  As described above, the garbage enclosed in the bag formed of the biodegradable polymer compound is heated evenly in the storage container as soon as possible, and the garbage enclosed in the bag is quickly heated and dried. It is possible to provide a garbage processing machine with a short processing time.

  As mentioned above, according to the garbage processing machine concerning this invention, the heating means for heating the convex-shaped part provided in the container bottom was operated, and the biodegradability high which has contacted the said convex-shaped part is operated. The bag formed by the molecular compound is melted, and the garbage enclosed in the bag can be heated evenly in the storage container as soon as the stirring means operates, and the bag is sealed in the bag. An object of the present invention is to provide a garbage processing machine that heats and dries food waste faster and has a shorter processing time.
