Description

[Technical Field]

[0001] The present invention relates to buildings, and more particularly to buildings configured to store garbage in an indoor storage space. [Background technology]

[0002] It is well known that a storage space is provided within a building such as a house, and garbage (specifically, food waste, plastic waste, etc.) is temporarily stored in the storage space. For example, in the house described in Patent Document 1, a garbage storage unit is provided on the kitchen counter, and garbage can be thrown into the garbage storage unit from the kitchen side. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-120019 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if garbage, especially food waste, is left to accumulate inside a building, odors will be generated due to the rotting of the garbage, polluting the environment inside the building. Also, if the garbage becomes bulky or if there is an excessive amount of garbage in the storage space, there is a possibility that the garbage will not be able to fit into the storage space.

[0005] On the other hand, if heated air could be injected into the waste storage space, it would dry out the waste and shrink it. However, if additional fuels such as natural gas or oil are consumed to generate heated air for waste disposal, this would incur costs and place a burden on household finances and building operations.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and its object is to provide a building that is configured to store garbage in an indoor storage space and that is capable of drying and shrinking the garbage in the storage space in a rational (economical) manner. [Means for solving the problem]

[0007] The above problem is solved by the building of the present invention, which comprises a garbage storage space provided within the building for storing garbage, and a duct extending from an opening located above a heating appliance within the building and through which air heated by use of the heating appliance flows, the duct having a portion extending into the garbage storage space. In a building of the present invention configured as described above, heated air can be recovered using heating equipment, and the recovered air can be used to dry and shrink the garbage in the garbage storage space in a rational (economical) manner.

[0008] In the building of the present invention, the duct may be branched at a midpoint into a first duct section extending to the garbage collection space and a second duct section extending to an exhaust port adjacent to the outdoor space. In this case, the duct may be provided with a valve for opening only one of the first duct section and the second duct section, and the valve may be operated to open only the first duct section when the heating appliance is in use. With the above configuration, heated air can be collected while the heating device is in use and the heated air can be appropriately sent to the waste collection space.

[0009] In the building of the present invention, the waste storage space may include a first storage space for storing food waste and a second storage space for storing plastic waste. In this case, the first duct portion may branch midway through the first duct portion into a third duct portion extending to the first storage space and a fourth duct portion extending to the second storage space. With the above configuration, food waste and plastic waste can be stored separately in the waste storage space, and each type of waste can be processed (specifically, dried and shrunk) using air heated by a heating device.

[0010] In addition, in the building of the present invention, a bottom plate that forms the bottom of the first storage space and has a plurality of through holes for drainage formed therein may be arranged in the first storage space, and a drainage groove that receives water that has passed through the through holes may be provided below the bottom plate. With the above configuration, water and liquids derived from food waste can be quickly removed from the first storage space, and the food waste in the first storage space can be efficiently dried using air heated by using a heating device.

[0011] In addition, in the building of the present invention, each of the first storage space and the second storage space may be provided with a bottom plate that forms the bottom of each of the first storage space and the second storage space and can be inserted and removed from each of the first storage space and the second storage space. With the above configuration, the waste that has been dried and shrunk by the air heated by the use of the heating device can be properly removed from the first storage space and the second storage space.

[0012] The building of the present invention may further include a compaction mechanism for compacting the waste in the second storage space. With the above configuration, the waste in the second storage space, particularly the waste made of plastic material, can be compressed and made compact, making it easier to dispose of the waste made of plastic material.

[0013] The building of the present invention may also have a waste receiving space connected to the input port for receiving waste input from the input port. In this case, the waste receiving space and the waste storage space may be located adjacent to each other, and a movable door may be provided between the waste receiving space and the waste storage space. With the above configuration, the garbage receiving space and the garbage storage space are separated by the movable door, so that the movable door can block out odors generated from the garbage in the garbage storage space.

[0014] Furthermore, in the above configuration, it is more preferable if the movable door moves between a normal position separating the garbage receiving space from the garbage storage space and a communicating position where it extends further toward the garbage storage space than the normal position and connects the garbage receiving space to the garbage storage space, but does not move further toward the garbage receiving space than the normal position. In the above case, odors emanating from the garbage in the garbage collection space can be more reliably blocked.

[0015] Furthermore, in the building of the present invention, it is even more preferable if the heating equipment is a gas stove, the opening is provided in a wall adjacent to the gas stove, and the garbage collection space is provided below the gas stove. According to the above configuration, the exhaust heat generated by the use of the gas stove can be recovered, and the recovered exhaust heat can be efficiently used to dry and shrink the waste in the waste storage space. [Effects of the Invention]

[0016] According to the building of the present invention, the waste in the waste storage space can be dried and shrunk rationally (economically) by using air heated by the use of heating equipment. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] <<About a building according to one embodiment of the present invention>> A building according to one embodiment of the present invention (hereinafter referred to as this embodiment) will be described below with reference to the accompanying drawings. Note that the drawings illustrate each device somewhat simplified and schematic to make the explanation easier to understand. Furthermore, the size (dimensions) of each device and the spacing between devices shown in the drawings may differ from the actual size.

[0019] In the following description, the building according to this embodiment will be assumed to be a "residence." Here, the residence may be a detached house or a single dwelling unit in an apartment building. The present invention can also be applied to buildings other than residences, such as schools, public facilities such as nursing homes and hospitals, stores, offices, and other buildings for various purposes, as long as the building stores waste inside (indoors) and uses heating equipment.

[0020] (Outline of the building according to this embodiment) A house according to this embodiment (hereinafter referred to as house 10) has a kitchen K shown in FIG. 1 as one of the spaces inside the house (inside the building). A gas stove 20 is installed in the kitchen K as a heating appliance (strictly speaking, an appliance that uses fire), and a kitchen panel 22 (back panel) is provided at the rear side of the gas stove 20. The kitchen panel 22 forms a wall surface (inner wall) adjacent to the gas stove 20, and extends in the up-down direction (vertical direction) and the width direction of the kitchen K. Furthermore, an outer wall 12 of the house 10 is provided on the opposite side of the gas stove 20 from the kitchen panel 22. The width direction of the kitchen K corresponds to the width direction of the gas stove 20, and is the direction in which the gas stove 20 and the sink are lined up.

[0021] 1, the kitchen panel 22 is provided with a ventilation opening 24, which is connected to a duct 30 installed inside the exterior wall 12 as shown in FIGS. 2 and 3. The opening 24 is located above the gas stove 20 in the kitchen K, and is located, for example, at a distance from the top edge (upper end surface) of the gas stove 20 that is equal to or greater than the distance specified by laws and regulations.

[0022] Duct 30 extends from opening 24, and heated air that enters duct 30 through opening 24 flows into duct 30. The heated air in duct 30 is air that is heated due to use of gas stove 20, and more specifically, air that is heated by the flame of gas stove 20 and radiant heat from cooking utensils. Exhaust gas generated by the combustion of natural gas when gas stove 20 is used may also be included in the air that is heated due to use of gas stove 20. The shape, size, material, etc. of the duct 30 are not particularly limited as long as they comply with standards set forth by law or government ordinance, and can be determined arbitrarily, for example, under conditions that satisfy the design specifications of the duct 30. The installation route of the duct 30 is also not particularly limited, and may be set to a route that is suitable for the structure and specifications of the house 10, etc.

[0023] 2 and 3, the duct 30 branches midway into a first duct portion 32 that extends to a waste collection space 50, which will be described later, and a second duct portion 34 that extends to an exhaust port 40 adjacent to the outdoor space. The exhaust port 40 is formed on the outdoor side of the exterior wall 12, and as shown in FIGS. 2 and 3, the exhaust port 40 may be covered with a weather cover 46 to prevent rainwater and the like from entering through the exhaust port 40. Instead of the weather cover 46, a louver (not shown) may be attached to the exhaust port 40.

[0024] 2 and 3, the first duct portion 32 and the second duct portion 34 are provided with a first valve 42 and a second valve 44 as duct switching valves near the branching point of the duct 30, respectively. The first valve 42 and the second valve 44 are valves for opening only one of the first duct portion 32 and the second duct portion 34, and can be opened and closed freely, and are constituted by, for example, known valves and dampers.

[0025] The first valve 42 and the second valve 44 are operated to switch the open state of each duct section, and are operated so that the first duct section 32 is open when the gas stove 20 is in use. Specifically, when the gas stove 20 is in use (i.e., when open flames are being used), the first valve 42 provided in the first duct section 32 is opened, and the second valve 44 provided in the second duct section 34 is closed. As a result, when the gas stove 20 is in use, only the first duct section 32 is open, and the second duct section 34 is closed. On the other hand, when the gas stove 20 is not in use, the second valve 44 is opened and the first valve 42 is closed, so that the first duct section 32 is closed and the second duct section 34 is open.

[0026] In this embodiment, the first valve 42 and the second valve 44 are solenoid valves, and when the gas stove 20 is started, a controller (not shown) controls the first valve 42 and the second valve 44 in conjunction with the start of the gas stove 20, switching the opening and closing of each valve in the above-mentioned manner. However, without being limited to this, the first valve 42 and the second valve 44 may be valves that are manually operated by a person.

[0027] As shown in Figures 2 to 4, the kitchen K is also provided with a waste collection space 50, which in this embodiment is provided in a cabinet 26 located directly below the gas stove 20. The waste collection space 50 collects food waste generated by cooking and other processes, as well as plastic waste used for packaging, containers, and the like (hereinafter referred to as plastic waste). More specifically, the waste collection space 50 is divided into two spaces in the width direction of the kitchen K, and includes a first collection space 52 for collecting food waste and a second collection space 54 for collecting plastic waste, as shown in Figure 4.

[0028] 2 and 3, the duct 30 extends to the garbage storage space 50. More specifically, as shown in Fig. 4, the first duct section 32 of the duct 30 branches midway into a third duct section 36 that extends to the first storage space 52 and a fourth duct section 38 that extends to the second storage space 54. This allows heated air (indicated by arrows in the figures) that enters the duct 30 from the opening 24 to be sent through the duct 30 to each of the first storage space 52 and the second storage space 54.

[0029] As shown in Figure 4, a partition wall 56 is provided between the first storage space 52 and the second storage space 54, and this partition wall 56 separates the two storage spaces in the width direction of the kitchen K. Also, as shown in Figures 2 and 3, bottom plates 58, 60 that form the bottom of each garbage storage space are disposed in the first storage space 52 and the second storage space 54. Each bottom plate 58, 60 is made of a plate made of metal such as aluminum or stainless steel, and garbage is placed on its upper surface. Food waste is stored in the first storage space 52 in a net-like bag (a so-called draining bag), and plastic waste is stored in the second storage space 54 in, for example, a plastic bag (garbage bag).

[0030] Each of the first and second storage spaces 52, 54 is adjacent to the exterior wall 12, through which the duct 30 is installed, and communicates with the outdoor space via a ventilation sleeve 14 provided at the lower end of the exterior wall 12. That is, the air in each garbage storage space is exhausted to the outdoor space through the ventilation sleeve 14, as shown in Figures 2 and 3.

[0031] 2 and 4, the bottom plate 58 of the first storage space 52 is made of punched metal and has a plurality of through-holes for drainage. Also, as shown in Fig. 2, a drain groove 16 that is V-shaped in side view is provided below the bottom plate 58. This drain groove 16 is provided to receive water that has passed through the through-holes of the bottom plate 58, for example, water derived from food waste stored in the first storage space 52, and to allow the water to flow toward a predetermined drainage destination.

[0032] Furthermore, in this embodiment, as shown in Fig. 5, a compression mechanism 76 is further provided that presses and compresses the waste (more specifically, plastic waste) in the second storage space 54. Specifically, the bottom plate 60 of the second storage space 54 can be raised and lowered by a lift 78 provided directly below the bottom plate 60. Furthermore, the ceiling plate 82 of the second storage space 54 can be moved up and down by a jack 80 provided directly above the ceiling plate 82. Then, as shown in Fig. 5, the bottom plate 60 is lowered and the ceiling plate 82 is lowered, whereby the plastic waste in the second storage space 54 is press-compressed.

[0033] The drive system of the lift 78 may be hydraulic, mechanical, or other drive systems. The compression mechanism 76 may be controlled by a controller (not shown), and for example, after a predetermined time has elapsed since the plastic waste was stored in the second storage space 54, the controller may control the compression mechanism 76 to perform press compression by the compression mechanism 76.

[0034] 2 and 3, a waste inlet 66 is provided at the front end of the cabinet 26, and waste receiving spaces 68, 70 are provided continuous with the inlet 66. An opening / closing door 74 is attached to the inlet 66, and the opening / closing door 74 is normally closed, but when waste is to be inserted, the opening / closing door 74 is opened to expose the inlet 66. The opening and closing door 74 may be a door that can swing in the depth direction of the cabinet 26 (for example, a downward / upward swing door), a drawer door, or a hinged door.

[0035] The waste receiving spaces 68, 70 are spaces that receive waste thrown in through the drop opening 66, and in this embodiment, as shown in Fig. 4, are divided into two spaces by the partition wall 56. One of the waste receiving spaces 68 is located adjacent to the first storage space 52 in the depth direction of the cabinet 26 (hereinafter referred to as the depth direction), as shown in Fig. 2. The other waste receiving space 70 is located adjacent to the second storage space 54 in the depth direction, as shown in Fig. 3. As shown in FIGS. 2 and 3, the lower surface of each of the waste receiving spaces 68, 70 is inclined downward toward the waste storage space 50.

[0036] 2 and 3, a movable door 72 is provided between each waste receiving space 68, 70 and each waste storage space 50 to separate these spaces. The movable door 72 can swing in the depth direction, specifically, it can move between a normal position and a communication position. The normal position is a position where the movable door 72 separates the waste receiving spaces 68, 70 from the waste storage space 50, and is the position shown by the solid line in FIGS. 2 and 3. The communication position is a position where the movable door 72 is positioned closer to the waste storage space 50 (i.e., the back side) in the depth direction than the normal position, so that the waste receiving spaces 68, 70 communicate with the waste storage space 50, and is the position shown by the dashed line in FIGS. 2 and 3.

[0037] The movable door 72 is normally located in the normal position, and is moved from the normal position to the communication position when it is pushed toward the rear in the depth direction by waste thrown into the waste receiving spaces 68, 70 from the throw-in opening 66. This causes the waste in the waste receiving spaces 68, 70 to move into the waste storage space 50 (specifically, the first storage space 52 or the second storage space 54).

[0038] On the other hand, the movable door 72 does not move further toward the waste receiving space (i.e., toward the front) than its normal position in the depth direction of the cabinet 26. This prevents waste that has moved to the waste storage space 50 (specifically, the first storage space 52 or the second storage space 54) from moving back toward the waste receiving spaces 68, 70. It also prevents air from within the waste storage space 50 from flowing (backflowing) toward the waste receiving spaces 68, 70. As a result, it is possible to prevent odors generated by the waste within the waste storage space 50 and heated air sent into the waste storage space 50 through the duct 30 from being released into the kitchen K through the waste receiving spaces 68, 70 and the input port 66.

[0039] Furthermore, in this embodiment, the bottom plates 58, 60 of each waste storage space are provided so as to be retractable relative to the respective waste storage spaces, specifically, they can be pulled out of the cabinet 26 or pushed into the cabinet 26 (see FIGS. 6 and 7). Because the bottom plates 58, 60 of each waste storage space are retractable relative to the respective waste storage spaces in this way, waste stored in each waste storage space can be removed from the waste storage space 50, specifically, from the cabinet 26.

[0040] The configuration for enabling the bottom plates 58, 60 of each waste collection space to be inserted and removed from the respective waste collection spaces is not particularly limited, and may be, for example, a configuration similar to an insertion and removal mechanism employed in a desk drawer, etc. In this embodiment, as shown in FIGS. 1 to 3 , the lower end of the cabinet 26 is provided at its front end with a drawer door 62 that is slidable in the depth direction of the cabinet 26. The drawer door 62 is connected to the bottom plates 58, 60 via a plate-shaped connecting portion 64. Therefore, when the drawer door 62 is inserted or removed in the depth direction of the cabinet 26, the bottom plates 58, 60 slide integrally with the drawer door 62, thereby allowing the bottom plates 58, 60 to be pulled out of the cabinet 26 or pushed into the cabinet 26.

[0041] In this embodiment, a drawer door 62 and a connecting portion 64 are provided separately for each of the bottom plate 58 of the first storage space 52 and the bottom plate 60 of the second storage space 54, so that the two bottom plates 58, 60 can be taken in and out separately. Furthermore, because the bottom plate 60 of the second housing space 54 moves up and down during press compression by the compression mechanism 76 described above, it is preferable that the connection part 64 on the second housing space 54 side be detachably connected to the bottom plate 60. For example, it is preferable that a magnet be attached to the tip of the connection part 64 (the end facing the bottom plate 60), and that the connection part 64 be connected to the bottom plate 60 by its magnetic force.

[0042] In the house 10 having the kitchen K configured as described above, the exhaust heat generated by use of the gas stove 20, specifically the heated air generated by use of the gas stove 20, can be recovered and the heated air can be sent to the waste collection space 50 through the first duct portion 32 of the duct 30. This allows the heated air to be used to dispose of the waste in the waste collection space 50.

[0043] More specifically, the food waste stored in the first storage space 52 can be dried and shrunk by heated air. In this embodiment, the bottom plate 58 of the first storage space 52 is provided with a plurality of drainage through-holes, and a drain groove 16 for receiving water that passes through the through-holes may be provided directly below the bottom plate 58. This allows water and liquid matter derived from the food waste to be quickly removed from the first storage space 52, and the food waste in the first storage space 52 can be efficiently dried by the heated air. As a result, the food waste is made more compact, which reduces the space required to store the food waste and makes it easier to dispose of the food waste.

[0044] In addition, the plastic waste stored in the second storage space 54 can be shrunk by heated air, thereby compacting the plastic waste. Furthermore, in this embodiment, a compression mechanism 76 is provided, which compresses the plastic waste in the second storage space 54, thereby making it even more compact. As a result, the storage space for the plastic waste can be reduced, and disposal of the plastic waste can be made easier.

[0045] In addition, the dried and shrunk garbage can be removed from the garbage storage space 50 at an appropriate time; specifically, the garbage can be removed from each garbage storage space by pulling out the bottom plates 58, 60 of the first storage space 52 and the second storage space 54, respectively.

[0046] <<Other embodiments>> While one embodiment of the building of the present invention has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and does not limit the present invention. In other words, the present invention can be modified and improved without departing from the spirit of the present invention. Furthermore, it goes without saying that the present invention also includes equivalents thereof.

[0047] Furthermore, in the above embodiment, the waste collection space 50 is located below the gas stove 20, specifically directly below it, but this is not limited to this, and the waste collection space 50 may be located away from the gas stove 20, for example, in a corner of the kitchen K. However, from the perspective of efficiently supplying the heated air generated by use of the gas stove 20, i.e., the exhaust heat, to the waste collection space 50 and making effective use of it, it is preferable that the waste collection space 50 be located near the gas stove 20, and in this respect, the above embodiment is a more effective configuration.

[0048] Furthermore, in the above embodiment, the opening 24 through which heated air generated by use of the gas stove 20 passes before entering the duct 30 is provided in the wall adjacent to the gas stove 20, specifically in the kitchen panel 22. However, the location of the opening 24 is not particularly limited as long as it is a location through which heated air can pass, and it may be located above the gas stove 20, for example, in a general range hood. However, from the perspective of efficiently supplying heated air, i.e., exhaust heat, to the waste collection space 50 and making effective use of it, it is preferable that the opening 24 be located near the gas stove 20, and in this respect, the above embodiment is a more effective configuration.

[0049] Furthermore, in the above embodiment, an example of a configuration in which the bottom plates 58, 60 forming the bottom of the waste storage space 50 can be pulled out relative to the waste storage space 50 has been described as a configuration for removing waste from the waste storage space 50. However, the configuration for removing waste from the waste storage space 50 is not limited to the above configuration. For example, the waste storage space 50 and the adjacent waste receiving spaces 68, 70 may form a box body (box structure), and the entire box body may be configured to be able to be inserted into and removed from the cabinet 26.

[0050] Furthermore, in the above embodiment, a gas stove 20 was cited as an example of a heating appliance, and a configuration using heated air generated by use of the gas stove 20 was described, but this is not limited to this. That is, the present invention is also applicable to cases where heating appliances other than a gas stove 20 are used within a building. Specifically, as another embodiment of the present invention, a configuration in which heated air generated by use of an appliance that uses fire, such as a kerosene stove or a gas water heater, is recovered as exhaust heat and used to dry and shrink waste is conceivable. Furthermore, the heating appliance is not limited to an appliance that uses fire, as long as it heats the surrounding air when used, and may be an electric appliance such as an induction cooker.
