Description

Technical Field

[0001] The present invention relates to a weight reduction and volume reduction processing device. More specifically, it relates to a weight reduction and volume reduction processing device capable of performing weight reduction and volume reduction processing on waste containing moisture such as food waste.

Background Art

[0002] Conventionally, in order to reduce the cost of disposing of garbage generated at home and the like, technologies for reducing the weight and volume of garbage have been developed. If the weight and volume of garbage can be reduced, the transportation cost and combustion cost of garbage can be reduced, and it also contributes to the reduction of greenhouse gases. In addition, the space for storing garbage at home can be reduced, and the spoilage of garbage can be suppressed, so the storage period can be extended to a certain extent. Then, the advantage of reducing the number of garbage collections can also be obtained.

[0003] For example, in the case of waste containing moisture such as food waste discharged from homes, there is a possibility of generating a bad smell due to spoilage during storage. To solve such problems, devices for drying waste containing moisture with warm air have been developed (Patent Documents 1 and 2).

[0004] In the technologies of Patent Documents 1 and 2, a configuration is adopted in which warm air is supplied to the waste from the upper surface of the waste in a state where the waste is accommodated in a container having through holes at the bottom. By adopting such a configuration, the warm air supplied from the upper part of the waste passes through the waste, and the warm air that has passed through the waste is discharged from the through holes at the bottom of the container, so that the warm air can be sequentially brought into contact with the waste, and thus the waste can be effectively dried.

Embodiments for Carrying Out the Invention

[0011] Next, embodiments of the present invention will be described based on the drawings. The weight-reducing and volume-reducing processing device of the present invention is a device for reducing the weight and volume of the object to be processed, and dries and reduces the weight and volume of the object to be processed by bringing heated air into contact with the object to be processed, and is characterized in that the drying efficiency of the object to be processed can be improved.

[0012] Note that the object to be processed processed by the weight-reducing and volume-reducing processing device of the present invention is not particularly limited. For example, household garbage discharged from homes can be cited, but it is not limited to these.

[0013] <Weight-Reducing and Volume-Reducing Processing Device 1> As shown in FIGS. 2 and 3, the weight and volume reduction processing apparatus 1 of the present embodiment includes a case main body 10, a heated air supply unit 20, and an exhaust unit 30 (see FIGS. 7 and 8). Further, it includes a storage container 50 disposed inside the case main body 10. In the weight and volume reduction processing apparatus 1 of the present embodiment, when the object to be processed is stored in the storage container 50 and the storage container 50 is placed inside the case main body 10, the object to be processed can be heated and dried by the heated air supplied from the heated air supply unit 20.

[0014] <Case main body 10> As shown in FIGS. 2 and 3, the case main body 10 has an accommodation space 10h inside. This accommodation space 10h is a space for accommodating the storage container 50 containing the object to be processed and drying the object to be processed in the storage container 50 to reduce its weight and volume. The case main body 10 has an opening 10a communicating between the accommodation space 10h and the outside on the front surface, and a door 11 for opening and closing this opening 10a. That is, by opening and closing the door 11, the storage container 50 can be taken in and out of the accommodation space 10h through the opening 10a, and when the door 11 is closed, the space between the accommodation space 10h and the outside can be hermetically sealed. As shown in FIG. 5, inhibition protrusions 15 are provided on three side surfaces of the accommodation space 10h, that is, the side surface 10b (rear surface 10b) on the rear side and a pair of side surfaces 10c, 10c sandwiching the rear surface 10b. The reason for this will be described later.

[0015] The door 11 is sized such that when the weight reduction / volume reduction processing device 1 (i.e., the case body 10) is viewed from the front, the body 11a can completely cover the opening 10a (see Figure 1), and the inner surface of the body 11a is equipped with an insertion portion 11b (see Figures 2 and 3). The insertion portion 11b is shaped to be approximately the same size and shape as the opening 10a, and when the door 11 is closed, it is inserted into the opening 10a, and the gap between the sides of the insertion portion 11b (top surface, bottom surface, and a pair of sides) and the inner surface of the storage space 10h becomes very small (for example, 1 mm or less). Moreover, a contact surface is provided around the insertion portion 11b on the inner surface of the body 11a that makes surface contact with the wall surface of the case body 10 surrounding the opening 10a. Furthermore, a packing p is provided on the wall surface of the case body 10 surrounding the opening 10a, in the portion where the contact surface of the door 11a makes surface contact with the wall surface of the case body 10 surrounding the opening 10a, so as to surround the opening 10a.

[0016] Therefore, when the door 11 is opened, the storage container 50 can be placed into the storage space 10h through the opening 10a, and when the door 11 is closed, the storage space 10h can be airtightly isolated from the outside with the storage container 50 inside. Moreover, when the door 11 is closed, the insertion part 11b is inserted into the opening 10a, and only a very narrow gap is created between the side of the insertion part 11b and the inner surface of the storage space 10h (the inner surface that forms the opening 10a). Furthermore, since the contact surface of the main body 11a and the surrounding wall surface of the opening 10a are sealed by the packing p provided to surround the opening 10a, the airtightness between the storage space 10h and the outside can be made very high. In addition, since the door 11 is provided with an insertion part 11b and, as described above, the gap between the side of the insertion part 11b and the inner surface of the storage space 10h is very small, the door 11 can be positioned and placed in a predetermined position when the door 11 is closed. When the door 11 is closed, the inner surface of the insertion section 11b (and the inner surface of the main body 11a) becomes the front side of the storage space 10h. For convenience, the front side of the storage space 10h is sometimes referred to as side 10f.

[0017] <Heated air supply unit 20> As shown in Figures 2 and 3, in the case body 10, a space 10h2 (see Figure 6) is provided on the rear side of the storage space 10h, separated from the storage space 10h. A blower 21 of the heated air supply unit 20 is installed in this space 10h2. This blower 21 is a known blower such as a sirocco fan, and its suction port is in airtight communication with an air suction port g1 formed on the rear surface 10b of the storage space 10h. In other words, the blower 21 is able to draw in gas from within the storage space 10h through the air suction port g1 on the rear surface 10b. Furthermore, the exhaust port of the blower 21 is in communication with the storage space 10h through an airflow channel 22. Specifically, a heated air supply port g2 is provided on the ceiling surface 10t of the storage space 10h, and this heated air supply port g2 and the exhaust port of the blower 21 are in communication through the airflow channel 22. In other words, by operating the blower 21, the air in the containment space 10h can be circulated by flowing it in the following order: air intake port g1, blower 21, airflow path 22, and heated air supply port g2.

[0018] As shown in Figures 2 and 3, a heating means 23, such as a heater, is provided in the middle of the airflow path 22 (i.e., between the heated air supply port g2 and the exhaust port of the blower 21). In other words, the air flowing from the exhaust port of the blower 21 through the airflow path 22 can be heated by the heating means 23.

[0019] Therefore, by properly operating the blower 21 and heating means 23 of the heated air supply unit 20, it is possible to create a state in which heated air at a predetermined temperature flows into the containment space 10h. In other words, by drawing in the air in the containment space 10h and returning it to the containment space 10h as heated air heated to a predetermined temperature, the air can be heated repeatedly by the heating means 23, making it easier to maintain the temperature of the heated air supplied to the containment space 10h above the predetermined temperature. Furthermore, the energy required to heat the air to the predetermined temperature by the heating means 23 can also be reduced. Moreover, even if the heating period by the heating means 23, that is, the time in contact between the air and the heating means 23, is shortened, it becomes easier to raise the heated air to the predetermined temperature. As a result, the flow velocity of the airflow flowing into the containment space 10h from the heated air supply port g2 can also be increased, thus improving the drying efficiency of the material to be processed.

[0020] The position of the heated air supply port g2 on the ceiling surface 10t of the containment space 10h is not particularly limited, but it is desirable that it be formed so as to be located directly above the containment container 50 when the containment container 50 is housed in the containment space 10h (see Figure 2).

[0021] <Exhaust section 30> As shown in Figure 1, an exhaust port 1d is formed on the top surface of the case body 10. This exhaust port 1d is connected to the exhaust port of the blower 21 of the heated air supply unit 20 via an exhaust section 30 (see Figures 7 and 8). In other words, a portion of the air drawn into the containment space 10h by the blower 21 of the heated air supply unit 20 can be discharged to the outside via the exhaust section 30. By discharging a portion of the air to the outside while introducing outside air into the containment space 10h in this way, the humidity of the circulating air (in other words, the humidity of the heated air supplied to the containment space 10h) can be kept within a certain range, thereby enabling effective drying of the workpiece using heated air.

[0022] Since the weight reduction / volume reduction processing device 1 of this embodiment has the above configuration, by properly operating the blower 21 and heating means 23 of the heated air supply unit 20, heated air at a predetermined temperature can be brought into contact with the object to be processed in the containment container 50 contained in the containment space 10h. Therefore, the object to be processed in the containment container 50 can be heated and dried with heated air. Moreover, since the air in the containment space 10h is drawn in and heated to a predetermined temperature and returned to the containment space 10h as heated air, it becomes easier to maintain the temperature of the heated air supplied to the containment space 10h above the predetermined temperature, and the energy required to heat the air drawn in from the containment space 10h to the predetermined temperature can also be reduced.

[0023] <Regarding the containment container 50 and the obstructing protrusions 15> In the weight reduction / volume reduction processing apparatus 1 of this embodiment, obstructing protrusions 15 are provided on the inner surface of the containment space 10h, and furthermore, the containment container 50 has the following configuration, so that the processing of the material to be processed contained in the containment container 50 can be performed more effectively. The containment container 50 and the obstructing protrusions 15 will be described in detail below.

[0024] <Storage container 50> As shown in Figures 10 to 12, the storage container 50 includes a first container 51 and a second container 52 attached to the bottom of the first container 51.

[0025] The first container 51 is a bottomed cylindrical member having an opening 51a at its upper end, and its cross-sectional shape is formed to be approximately rectangular. The bottom wall 51b of the first container 51 is formed to be breathable. For example, ventilation parts s such as slits or through holes (see Figures 11(B) and 12(B)) are formed in the bottom wall 51b, and air can be passed between the internal space 51h of the first container 51 and the outside through these ventilation parts s (see Figures 11(B) and 12(B)). In other words, heated air supplied to the first container 51 from the opening 51a can pass through to the object to be processed. The first container 51 is provided with a flange portion 51f formed by folding its upper end outwards. This flange portion 51f is provided so as to surround the opening 51a of the first container 51. Furthermore, the bottom wall 51b of the first container 51 is provided with legs 51c, so that when the second container 52 is attached to the bottom of the first container 51, a gap 50s is created between the bottom wall 51b of the first container 51 and the inner bottom surface 52b of the second container 52. In other words, a gap 50s is provided that allows heated air that has passed through the ventilation section s of the bottom wall 51b of the first container 51 to flow in.

[0026] The second container 52 is a bottomed member having an opening 52a at its upper end. The second container 52 is attached to cover the bottom of the first container 51 by inserting the bottom of the first container 51 through the opening 52a. The bottom wall of the second container 52 is constructed to be impermeable to liquids and gases, while when the bottom of the first container 51 is attached to the opening 52a, a communication gap 52h is formed between the side surface (first side surface f1) of the first container 51 and the inner surface of the side wall of the second container 52, which is in communication with the aforementioned gap 50s (see Figures 4 and 12(B)). Specifically, when the container is housed in the storage space 10h of the case body 10, there is no gap (or only a very narrow gap) between the side surface (second side surface f2) of the first container 51 and the inner surface of the side wall of the second container 52 in the parts facing the front surface 10a and the back surface 10b of the storage space 10h. However, in the parts located on the pair of side surfaces 10c, 10c, a communication gap 52h is formed between the first side surface f1 of the first container 51 and the inner surface of the side wall of the second container 52.

[0027] The first container 51 may simply have a structure in which its bottom is inserted into the second container 52, but it is desirable that it has a mechanism that can connect the two and fix their movement. For example, as shown in Figures 10 to 12, through holes g (or recesses) are provided near the bottom of the second side surface f2 of the first container 51, and fixing pieces t that engage with the through holes g of the second side surface f2 are provided at the upper ends of the opposing side walls of the second container 52. Then, by attaching the bottom of the first container 51 to the opening 52a of the second container 52, the first container 51 and the second container 52 can be connected and their movement fixed by engaging the fixing pieces t with the through holes g.

[0028] <Inhibitory protrusion 15> As shown in Figures 3 and 5, obstructing protrusions 15 are provided on the inner surface of the containment space 10h. Specifically, rear obstructing protrusions 15b are provided on the back surface 10b of the containment space 10h, and lateral obstructing protrusions 15c are provided on a pair of side surfaces 10c, 10c, that is, a pair of side surfaces 10c, 10c that sandwich the back surface 10b.

[0029] First, the lateral obstruction projection 15c is a portion that protrudes from the side surface 10c and extends from the rear side to the front side of the containment space 10h (see Figure 3). This lateral obstruction projection 15c is provided to reduce the gap between the side surface of the first container 51 of the containment container 50 and the side surface 10c of the containment space 10h. In other words, it is provided to act as resistance when heated gas passes through the gap between the side surface of the first container 51 of the containment container 50 and the side surface 10c of the containment space 10h. More specifically, when the containment container 50 is contained within the containment space 10h, the upper surface of the lateral obstruction projection 15c is located below the upper end of the first container 51 of the containment container, specifically below the lower end of the flange portion 51f, and the lower surface is located above the upper end of the second container 52 of the containment container 50. Furthermore, when the containment container 50 is housed within the containment space 10h, the lateral obstruction projection 15c is formed such that, when viewed from above, the lateral obstruction projection 10c overlaps with the flange portion 51f. In other words, the lateral obstruction projection 15c is formed such that the distance from the outer surface of the flange portion 51f to the side surface 10c of the containment space 10h is shorter than the distance from the tip of the lateral obstruction projection 15c to the side surface 10c of the containment space 10h (see Figure 4).

[0030] Furthermore, the rear obstruction projection 15b is a portion that protrudes from the rear surface 10b and is provided to extend along the direction connecting the pair of sides 10c, 10c of the containment space 10h (see Figure 5). This rear obstruction projection 15b is provided to reduce the gap between the side surface of the first container 51 of the containment container 50 and the rear surface 10b of the containment space 10h. In other words, it is provided to act as resistance when heated gas passes through the gap between the side surface of the first container 51 of the containment container 50 and the rear surface 10b of the containment space 10h. More specifically, when the containment container 50 is contained within the containment space 10h, the upper surface of the rear obstruction projection 15b is located below the upper end of the first container 51 of the containment container, more specifically below the lower end of the flange portion f, and the lower surface is located above the upper end of the second container 52 of the containment container 50 (see Figure 2). Furthermore, when the containment container 50 is housed within the containment space 10h, the rear obstruction projection 15b is formed such that it overlaps with the flange portion 51f when viewed from above. In other words, the rear obstruction projection 15b is formed such that the distance from the outer surface of the flange portion f to the rear surface 10b of the containment space 10h is shorter than the distance from the tip of the rear obstruction projection 15b to the rear surface 10b of the containment space 10h (see Figure 2). The rear obstruction projection 15b is positioned above the air intake port g1 formed on the rear surface 10b of the containment space 10h (see Figures 2 and 5).

[0031] By providing a containment container 50 with the shape described above, and obstructing protrusions 15 on the inner surface of the containment space 10h, heated air can be effectively brought into contact with the object to be processed inside the containment container 50. Specifically, by providing a rear obstructing protrusion 15b on the rear surface 10b of the containment space 10h, and a pair of lateral obstructing protrusions 15c, 15c on a pair of side surfaces 10c, 10c, heated air can be effectively brought into contact with the object to be processed inside the containment container 50. In other words, the amount of heated air that does not come into contact with the object to be processed inside the containment container 50 (i.e., does not flow into the containment container 50) and passes between the containment container 50 and the rear surface 10b or the pair of side surfaces 10c, 10c of the containment space 10h and is drawn into the air intake port g1 can be reduced, thus enabling effective processing of the object to be processed with heated air.

[0032] <Regarding the inhibitory projection 15> In the example described above, a case was explained in which a rear obstruction projection 15b is provided on the rear surface 10b of the storage space 10h of the case body 10, but the rear obstruction projection 15b is not necessarily required. However, providing the rear obstruction projection 15b enhances the effect of preventing heated air supplied to the storage space 10h through the heated air supply port g2 from flowing directly into the air intake port g1.

[0033] Furthermore, in the example described above, no obstructing protrusions are provided on the side surface 10f of the storage space 10h (i.e., the inner surface of the insertion portion 11b). However, obstructing protrusions (front obstructing protrusions) may also be provided on the side surface 10f of the storage space 10h to have the same function as the rear obstructing protrusions 15b and lateral obstructing protrusions 15c described above.

[0034] Furthermore, each inhibiting projection 15 may be provided with a protruding rib or the like at its tip. Providing a protruding rib or the like can further enhance the effect of preventing heated air from flowing directly into the air intake port g1.

[0035] Furthermore, each inhibiting projection 15 is formed such that a gap is created between it and the sides f1 and f2 of the containment container 50 when the containment container 50 is placed in the containment space 10h (see Figures 2 and 4), but it is also acceptable to have almost no gap. However, if a gap is created between each inhibiting projection 15 and the sides f1 and f2 of the containment container 50, even if the ventilation part s formed in the bottom wall 51b of the first container 51 of the containment container 50 is blocked and ventilation is lost, the flow of heated air in the containment space 10h can be maintained, and the drying treatment of the workpiece with heated air can be continued.

[0036] <Regarding container 50> The containment container 50, specifically the first container 51, does not necessarily have a flange portion 51f at its upper end. However, providing a flange portion 51f makes it easier to prevent heated air flowing into the containment space 10h from the heated air supply port g2 from flowing without entering the first container 51. In other words, it allows for effective contact between the heated air and the workpiece inside the containment container 50, thereby improving the processing efficiency of the workpiece.

[0037] The communication gap 52h formed between the side surface and the inner surface of the first container 51 may be formed in the portion facing the front surface 10a or rear surface 10b of the containment space 10h. In other words, a communication gap may also be formed between the second side surface f2 of the first container 51 and the inner surface of the side wall of the second container 52. However, if there is no communication gap 52h in the portion facing the front surface 10a or rear surface 10b of the containment space 10h (especially the portion facing the rear surface 10b), the heated air and the material to be processed in the containment container 50 can be brought into effective contact, thereby improving the processing efficiency of the material to be processed.

[0038] <Regarding the exhaust section 30> The exhaust section 30 only needs to be capable of discharging a portion of the air discharged from the exhaust port of the blower 21 of the heated air supply section 20, and its flow path configuration is not particularly limited. For example, it can have the following configuration.

[0039] As shown in Figures 7 and 8, the exhaust section 30 consists of a branched passage 31 connected to the exhaust port of the blower 21, a purification member housing section 33 connected to the exhaust port 1d of the case body 10, and a connecting passage 32 connecting the purification member housing section 33 and the branched passage 31.

[0040] As shown in Figures 2 and 3, the branched passage 31 is a space formed between the airflow passage 22 and the back of the case body 10, and its lower end opening is in communication with the exhaust port of the blower 21 (see Figure 6).

[0041] As shown in Figure 2, the purification member housing section 33 is a space that houses a purification member 35 for purifying the air, and the air discharged to the outside is configured to pass through the purification member 35 in the purification member housing section 33 before being discharged to the outside. This makes it possible to suppress the deterioration of the environment around the device due to the air discharged from the device while the material to be processed is being processed by the device. As the purification member 35, for example, a known deodorizer, a filter that removes harmful components contained in the air, activated carbon, etc., can be used.

[0042] As shown in Figure 8, the communication channel 32 consists of a bypass channel 32a and a supply channel 32b that supplies air flowing in from the bypass channel 32a to the lower end of the purification member housing section 33. The bypass channel 32a is a channel provided to the side of the air blowing channel 22, and the supply channel 32b is a channel provided in front of the air blowing channel 22 and above the housing space 10h. The bypass channel 32a is a channel that connects the supply channel 32b and the branch channel 31 (see Figures 4 and 7). The supply channel 32b is provided to reduce the flow velocity of the air supplied from the bypass channel 32a and is in communication with the purification member housing section 33. Specifically, as shown in Figure 8, the supply channel 32b is configured to reverse the flow of air coming from the bypass channel 32a before supplying it to the purification member housing section 33. In other words, air flows from the bypass channel 32a into the purification member housing section 33 as shown by the arrows in Figure 8. This allows the time that air passes through the purification member 35 in the purification member housing 32 to be extended, enabling the air to be effectively treated by the purification member 35, and also reduces noise by decreasing the airflow velocity of the air discharged from the exhaust port 1d.

[0043] <Regarding outside air intake> As mentioned above, since some of the air is discharged to the outside by the exhaust section 30, air is introduced into the containment space 10h from the outside in order to ensure a sufficient amount of circulating air. The structure for introducing air from the outside is not particularly limited. Since the space in which heated air flows within the containment space 10h and the volume reduction / reducing device 1 is basically under negative pressure relative to the outside air, it is also possible to introduce outside air naturally through gaps in the volume reduction / reducing device 1. However, if an appropriate amount of outside air is to be introduced appropriately, it is desirable to provide a flow path that connects the containment space 10h to the outside and introduce outside air into the containment space 10h. For example, the following intake mechanism 60 can also be used.

[0044] As shown in Figures 2 and 3, an air intake port 61h is formed on the back of the case body 10, connecting the inside of the case body 10 to the outside. Specifically, an introduction channel 61 for the intake mechanism 60 is provided inside the case body 10. This introduction channel 61 consists of a channel 61a formed along the back of the case body 10 (see Figures 6 and 9) and a pair of channels 61b, 61b extending forward from the lower end of the channel 61a (see Figure 9). At their tips, these two channels 61b, 61b are connected to internal channel 62 formed within a pair of lateral obstruction protrusions 15c, 15c. An outside air inlet g3 is provided at the front ends of the pair of lateral obstruction protrusions 15c, 15c (see Figures 3 and 9). In other words, the housing space 10h is connected to the outside via the air intake port 61h, the introduction channel 61 (channels 61a and 61b), the internal channel 62, and the outside air inlet g3. Therefore, when the blower 21 of the heated air supply unit 20 is activated, some of the air is discharged to the outside by the exhaust unit 30, creating negative pressure in the containment space 10h relative to the outside. This allows an amount of outside air corresponding to the air discharged to the outside to be introduced into the containment space 10h by flowing it in the following order: intake port 61h, introduction channel 61 (channels 61a and 61b), projection channel 62, and outside air inlet g3. Furthermore, the negative pressure in the containment space 10h relative to the outside also prevents air from leaking out of the containment space 10h. For example, it prevents air from leaking out through gaps between the door 11 and the main body 10. As a result, odors and other substances from the material to be processed contained in the containment space 10h while it is contained in the containment container 50 can be prevented from leaking to the outside, thus preventing deterioration of the surrounding environment while the material to be processed is being handled by the weight reduction / volume reduction processing device 1 of this embodiment.
