[0010] Hereinafter, embodiments of the garbage disposal device of the present invention will be described with reference to the drawings.

[0011] <Configuration example of garbage disposal device according to the present embodiment> Figure 1 is a side cross-sectional view showing an example of the garbage disposal device according to the present embodiment.

[0012] The garbage disposal device 100 includes a crushing chamber 101 into which garbage such as food waste is charged. The crushing chamber 101 is connected to an inlet 102 formed in an upper part of the garbage disposal device 100. In the garbage disposal device 100, the inlet 102 is exposed at an opening of a sink 200 provided in kitchen equipment (not shown).

[0013] The kitchen waste processing device 100 is equipped with a lid 1A that can be detachably attached to an input port 102, which is an example of an opening. When water, which is liquid, is poured into the sink 200 with the input port 102 closed by the lid 1A, the kitchen waste processing device 100 is supplied to the crushing chamber 101 via the lid 1A.

[0014] The kitchen waste processing device 100 is configured such that the lid 1A can be attached to the input port 102 in a detachable position. Furthermore, the kitchen waste processing device 100 is configured such that the lid 1A attached to the input port 102 can be fixed to and released from the input port 102 by rotating from the detachable position to a fixed position in the circumferential direction of the input port 102.

[0015] When the lid 1A is in a detachable position relative to the input opening 102, it is attached to the input opening 102 by moving it downward relative to the input opening 102. When the lid 1A is attached to the input opening 102, it is detached from the input opening 102 by moving it upward relative to the input opening 102 when it is in a detachable position.

[0016] The lid 1A is attached to the input opening 102 in a detachable position, and by rotating it in one direction to a fixed position, it is fixed in a state where it cannot be removed from the input opening 102 when moved upward relative to the input opening 102. Furthermore, by rotating the lid 1A from its fixed position on the input opening 102 to a detachable position in a direction opposite to the one direction, it is released from the input opening 102, and can be removed from the input opening 102 by moving it upward relative to the input opening 102.

[0017] The kitchen waste processing device 100 comprises a main body 103 installed below the sink 200 and a crushing unit 104 that constitutes a crushing chamber 101.

[0018] The main body 103 includes a mounting portion 103a to which the crushing portion 104 is attached. The mounting portion 103a consists of a roughly cylindrical inner space connected to the input port 102. The mounting portion 103a is configured so that the crushing portion 104 can be inserted from the input port 102. The mounting portion 103a is also configured so that the crushing portion 104 can be removed from the input port 102.

[0019] The main body 103 has a slope at the bottom 103b of the mounting portion 103a that slopes downward toward a drain pipe connection port (not shown). When the crushing portion 104 is attached to the mounting portion 103a of the main body 103, a space is formed between the crushing portion 104 and the bottom 103b. As a result, the kitchen waste processing device 100 is configured such that the crushed kitchen waste material crushed by the crushing portion 104 flows from the crushing portion 104 to the bottom 103b due to the water supply to the crushing portion 104, and further flows toward the drain pipe connection port due to the slope of the bottom 103b.

[0020] The crushing unit 104 comprises a container 104a that constitutes the crushing chamber 101, a rotary crushing unit 104b that is rotatably mounted relative to the container 104a, and a fixed crushing unit 104c that is mounted on the container 104a.

[0021] The container 104a has a substantially cylindrical shape with a bottom portion 104d, and its substantially cylindrical outer shape is configured to fit into the mounting portion 103a of the main body portion 103. Furthermore, the crushing chamber 101 is formed in the space inside the substantially cylindrical shape of the container 104a.

[0022] The rotary crushing section 104b is a crushing blade that rotates together with the crushing arm section 104b1 around the shaft 104e. In this example, as shown in Figure 1, the crushing arm section 104b1 extends horizontally in two opposing directions around the shaft 104e, and also extends vertically downward from the end of the crushing arm section 104b1, thereby crushing the food waste in the crushing chamber 101 between the rotary crushing section 104b and the fixed crushing section 104c. The crushing section 104 is equipped with a turntable 104b2 on the shaft 104e for stirring water and food waste.

[0023] The fixed crushing section 104c is composed of a protrusion or the like that protrudes in a predetermined shape at a predetermined position within the crushing chamber 101. The fixed crushing section 104c may be configured by attaching a separate part to the container 104a, or it may be integrated with the container 104a.

[0024] The kitchen waste processing device 100 is configured such that the crushing unit 104 is inserted into the mounting part 103a from the input port 102, and the crushing unit 104 can be attached to the mounting part 103a. Furthermore, the kitchen waste processing device 100 is configured such that the crushing unit 104 attached to the mounting part 103a can be removed from the input port 102, and the crushing unit 104 can be removed from the mounting part 103a to clean the container 104a, the rotary crushing unit 104b, and the fixed crushing unit 104c.

[0025] Furthermore, in the kitchen waste processing device 100, when the crushing unit 104 is attached to the mounting unit 103a, the shaft 104e is connected to the shaft 104f which is connected to a motor (not shown), and when the crushing unit 104 is removed from the mounting unit 103a, the connection between the two shafts 104e is released.

[0026] Furthermore, the kitchen waste processing device 100 uses a sensor (not shown) that detects the opening and closing of the lid 1A to configure a switch for starting and stopping crushing. When the kitchen waste processing device 100 detects that the lid 1A, which is attached to the input port 102, has rotated in one direction from the detachable position to the fixed position, a motor (not shown) is driven to rotate the rotary crushing unit 104b and crushing begins. Also, when the lid 1A, which has been detected to have rotated to the fixed position, rotates in another direction from the fixed position to the detachable position and is no longer detected, the motor (not shown) is stopped, the rotation of the rotary crushing unit 104b stops, and crushing stops.

[0027] <Example of the lid configuration in this embodiment> Figure 2A is a side cross-sectional view showing an example of the lid of this embodiment, and Figure 2B is a side cross-sectional view of the main part showing an example of the lid of this embodiment. Figure 3 is an exploded perspective view showing an example of the lid of this embodiment. Furthermore, Figure 4A is a view of the surface of an example of the lid of this embodiment, Figure 4B is a view of the back of an example of the lid of this embodiment, and Figure 4C is a side view showing an example of the lid of this embodiment. Note that Figure 2A is a side cross-sectional view obtained by cutting Figure 4A along line AA.

[0028] The lid portion 1A comprises a lower lid portion 2A for storing water and an upper lid portion 3 attached to the lower lid portion 2A. The lower lid portion 2A is an example of a lid portion and comprises a bottom portion 20 and a first hole portion 21 and a second hole portion 22 that penetrate the bottom portion 20.

[0029] The lower cover portion 2A has a shape in which a substantially cylindrical side wall portion 23 rises upward in the first direction from the outer circumference 20a of the substantially circular bottom portion 20.

[0030] In this example, the center of rotation for fixing and releasing the lid 1A relative to the input opening 102 is the center O1 of the bottom 20. The bottom 20 has a shape that is convex upward from the outer circumference 20a toward the center O1. The top 20b of the bottom 20 is the convex shape at the center O1 or a predetermined region including the center O1.

[0031] When the lid 1A is attached to the opening 102, the bottom lid 2A has a surface 20c of the bottom 20 which is sloped in a vertical direction from the top 20b towards the outer periphery 20a. In addition, the underside 20d of the bottom 20 of the bottom lid 2A has a surface 20d which is sloped in a vertical direction from the top 20b towards the outer periphery 20a, following the same pattern as the surface 20c.

[0032] The lower cover portion 2A is provided with a first hole 21 in the bottom portion 20. The first hole 21 penetrates from the surface 20c to the back surface 20d of the bottom portion 20 and is composed of a hole of a size that allows a predetermined amount of water to pass through in a predetermined amount of time. Furthermore, the first hole 21 is provided within a region E1 in the bottom portion 20. Region E1 is the area in the bottom portion 20 that is inside half of the radius R1 from the center O1 to the outer circumference 20a. As a result, the first hole 21 is provided in the bottom portion 20 on the side closer to the top portion 20b than to the outer circumference 20a.

[0033] The lower cover portion 2A has multiple first holes 21 arranged on concentric circles with a center O1 within the region E1. Alternatively, the lower cover portion 2A may be configured so that the multiple first holes 21 are arranged on multiple concentric circles with different radii.

[0034] The lower cover portion 2A is equipped with a guide portion 20e that guides water that has passed through the first hole portion 21 along the back surface 20d. The guide portion 20e is an example of an inclined portion, and the lower cover portion 2A is composed of inclined surfaces on the surface 20c and back surface 20d of the bottom portion 20, where the vertical height decreases from the top portion 20b toward the outer peripheral portion 20a, and the surface is inclined downward from the first hole portion 21. As a result, on the back surface 20d of the bottom portion 20, the part of the lower cover portion 2A toward the outer peripheral portion from the part where the opening 21c of the first hole portion 21 is exposed is inclined downward from the first hole portion 21. Thus, the guide portion 20e of the lower cover portion 2A is formed by the inclination of the bottom portion 20.

[0035] Furthermore, the lower cover portion 2A is provided with a second hole portion 22 in the bottom portion 20. The second hole portion 22 penetrates from the surface 20c to the back surface 20d of the bottom portion 20 and is composed of a hole of a size that allows a predetermined amount of water to pass through in a predetermined amount of time. Multiple second holes portion 22 are provided along the outer circumference 20a of the bottom portion 20 in the lower cover portion 2A.

[0036] Furthermore, the lower lid portion 2A is provided with a third hole 24 in the bottom portion 20. The third hole 24 penetrates from the surface 20c to the back surface 20d of the bottom portion 20 and is composed of a hole of a size that allows a predetermined amount of water to pass through in a predetermined amount of time. The lower lid portion 2A has one third hole 24 located inside the first hole 21, and in this example, when the lid portion 1A is attached to the input port 102, it is located above the shaft 104e.

[0037] The lower cover portion 2A is equipped with an outflow guide portion 21a on the back surface 20d side of the bottom portion 20 that guides the flow of water that has flowed out from the first hole portion 21. The lower cover portion 2A is also equipped with an inflow guide portion 21b on the front surface 20c side of the bottom portion 20 that guides the flow of water that has flowed into the first hole portion 21.

[0038] The outflow guide section 21a guides the water flowing out of the opening 21c through the first hole 21 to flow along the slope of the back surface 20d toward the outer periphery 20a of the bottom 20 indicated by arrow A1. Therefore, the outflow guide section 21a is constructed by providing a slope between the inner wall 21d of the first hole 21 and the opening 21c, which is inclined in a direction that causes the opening 21c to widen toward the outer periphery 20a of the bottom 20.

[0039] The inflow guide section 21b guides water near the top 20b on the surface 20c side of the bottom 20 so that it flows along the slope of the surface 20c toward the opening 21e of the first hole 21 exposed on the surface 20c. Therefore, the inflow guide section 21b is constructed by providing a slope between the inner wall 21d of the first hole 21 and the opening 21e, which is inclined in a direction that causes the opening 21e to widen toward the inside of the bottom 20.

[0040] The upper cover portion 3 has a shape that is concave downwards from the outer circumference toward the center, and the vicinity of the lower end of the concave shape is opposite the top portion 20b of the lower cover portion 2A, covering the space enclosed by the bottom portion 20 and the side wall portion 23 of the lower cover portion 2A. The upper cover portion 3 is provided with holes 30 and 31 through which water can pass. Hole 30 is provided in the upper cover portion 3 near the lower end of the concave shape. Hole 31 is provided on the outer circumference side of the upper cover portion 3.

[0041] <Examples of the operation and effects of the food waste processing device of this embodiment> The following describes examples of the operation and effects of the kitchen waste processing device 100 of this embodiment, with reference to the figures.

[0042] In the kitchen waste processing device 100, kitchen waste is placed in the crushing chamber 101, and a lid 1A is attached to the input port 102. When a predetermined amount of water flows into the sink 200 of the kitchen waste processing device 100, the water flowing from the sink 200 to the input port 102 passes through the holes 30 and 31 of the upper lid 3 of the lid 1A and is stored in the lower lid 2A.

[0043] The kitchen waste processing device 100 operates as follows: when a predetermined amount of water is flowed into the sink 200, a predetermined amount of water is stored in the lower lid 2A. The lid 1A rotates in one direction from the detachable position to the fixed position. When it is detected that the lid has rotated to the fixed position, a motor (not shown) is driven to rotate the rotating crushing unit 104b, and crushing begins. The predetermined water level L, at which the water supply to the sink 200 and the drainage from the lid 1A balance each other, is shown by a dashed line in Figure 2A. The height of the top 20b of the surface 20c is set so that it is lower than the predetermined water level L.

[0044] In the lid portion 1A, water stored in the lower lid portion 2A flows through the first hole 21, the second hole 22, and the third hole 24 to the crushing chamber 101. Water flowing out from the opening 21c through the first hole 21 is guided by the outflow guide portion 21a to flow along the slope of the back surface 20d of the bottom portion 20 toward the outer circumference 20a of the bottom portion 20 indicated by arrow A1.

[0045] The water flowing out of the opening 21c through the first hole 21 is guided by the inclination of the back surface 20d of the bottom 20 to flow along the back surface 20d toward the outer circumference 20a of the bottom 20, indicated by arrow A1. As a result, the food waste adhering to the back surface 20d of the lower lid 2A due to the crushing operation falls into the crushing chamber 101 by the flow of water that has passed through the first hole 21, and is further crushed by the rotary crushing section 104b and the fixed crushing section 104c.

[0046] Furthermore, the lid portion 1A is designed so that the water stored in the lower lid portion 2A flows along the slope of the surface 20c towards the opening 21e of the first hole portion 21, as guided by the inflow guide portion 21b. This ensures a sufficient amount of water flows out from the opening 21c through the first hole portion 21. Therefore, it is possible to suppress the remaining food waste adhering to the underside 20d of the lower lid portion 2A at the end of the crushing operation.

[0047] Furthermore, the water passing through the second hole 22 flows along the inner wall of the crushing chamber 101, as indicated by arrow A1. As a result, the food waste that has adhered to the inner wall of the crushing chamber 101 due to the crushing operation falls off due to the flow of water that has passed through the second hole 22, and is further crushed by the rotary crushing section 104b and the fixed crushing section 104c.

[0048] Furthermore, the water passing through the third hole 24 flows toward the shaft 104e and its vicinity, as indicated by arrow A3. As a result, food waste adhering to the shaft 104e and the vicinity of the shaft 104e of the rotating crushing section 104b falls off due to the flow of water that has passed through the third hole 24, and is further crushed by the rotating crushing section 104b and the stationary crushing section 104c.

[0049] <Examples of lid configurations in other embodiments> Figure 5A is a side cross-sectional view showing an example of a lid in another embodiment, and Figures 5B and 5C are side cross-sectional views of the main part showing an example of a lid in another embodiment. In the lid 1B shown in Figures 5A and 5B, the bottom 20 of the lower lid 2B has a shape that is convex upward from the outer circumference 20a toward the center O1. The lower lid 2B is an example of a lid, and the surface 20c of the bottom 20 is composed of a slope in which the vertical height decreases from the top 20b toward the outer circumference 20a. In addition, the back surface 20d of the bottom 20 of the lower lid 2B follows the surface 20c and is composed of a slope in which the vertical height decreases from the top 20b toward the outer circumference 20a.

[0050] The lower cover portion 2B is provided with a first hole 21, a second hole 22, and a third hole 24 in the bottom portion 20. The first hole 21, the second hole 22, and the third hole 24 have the same configuration as the cover portion 1A.

[0051] The lower cover portion 2B is equipped with outflow guide portions 21a and 21f on the underside 20d side of the bottom portion 20 to guide the flow of water that has flowed out from the first hole portion 21. The lower cover portion 2B is also equipped with an inflow guide portion 21b on the surface 20c side of the bottom portion 20 to guide the flow of water that has flowed into the first hole portion 21. The outflow guide portion 21a and the inflow guide portion 21b have the same configuration as the cover portion 1A.

[0052] The outflow guidance section 21f guides the water flowing out from the opening 21c through the first hole 21 to flow along the slope of the back surface 20d toward the outer circumference of the bottom 20 indicated by arrow A1.

[0053] Therefore, the outflow guide section 21f is configured such that a first protrusion 21f1 is provided on a part of the periphery of the opening 21c of the first hole 21 on the back surface 20d of the bottom section 20 to restrict the flow of water. The outflow guide section 21f is provided such that the first protrusion 21f1 is provided on the periphery of the opening 21c of the first hole 21 on the side toward the center of the bottom section 20, projecting downward from the back surface 20d.

[0054] Furthermore, the outflow guide section 21f is configured with a second protrusion 21f2 that restricts the flow of water at a portion facing the opening 21c of the first hole 21. The second protrusion 21f2 of the outflow guide section 21f is provided in a form that protrudes from the first protrusion 21f1 toward the outer circumference of the bottom 20. The second protrusion 21f2 protrudes from the back surface 20d and forms an opposing surface that is spaced apart from the first hole 21.

[0055] As a result, the outflow guidance section 21f restricts the flow of water flowing out of the opening 21c through the first hole 21 towards the center of the bottom 20 with the first protrusion 21f1, and guides the water flowing out of the opening 21c through the first hole 21 towards the outer periphery of the bottom 20. Furthermore, the outflow guidance section 21f uses the second protrusion 21f2 to guide the water flowing out of the opening 21c through the first hole 21 to flow along the slope of the back surface 20d towards the outer periphery of the bottom 20 indicated by arrow A1.

[0056] In Figure 5C, the lid 1C has a bottom 20 of the lower lid 2C that is horizontal from the outer periphery towards the center. The lower lid 2C is an example of a lid, and the surface 20c of the bottom 20 is composed of a substantially horizontal surface perpendicular to the vertical direction from the top 20b towards the outer periphery. In addition, the back surface 20d of the bottom 20 of the lower lid 2C follows the surface 20c and is composed of a substantially horizontal surface perpendicular to the vertical direction from the top 20b towards the outer periphery.

[0057] The lower cover portion 2C is provided with a first hole 21 in the bottom portion 20. The first hole 21 penetrates from the surface 20c to the back surface 20d of the bottom portion 20 and is composed of a hole of a size that allows a predetermined amount of water to pass through in a predetermined amount of time. Furthermore, the first hole 21 is provided on the bottom portion 20 closer to the top portion 20b than to the outer circumference.

[0058] The lower cover portion 2C is equipped with outflow guide portions 21a and 21f on the back surface 20d side of the bottom portion 20 to guide the flow of water that has flowed out from the first hole portion 21. The lower cover portion 2C is also equipped with an inflow guide portion 21b on the front surface 20c side of the bottom portion 20 to guide the flow of water that has flowed into the first hole portion 21.

[0059] In the lower cover portion 2C, the outflow guidance portion 21f, similar to the lower cover portion 2B, restricts the flow of water flowing out of the opening 21c through the first hole 21 toward the center of the bottom portion 20 with the first protrusion 21f1, and guides the water flowing out of the opening 21c through the first hole 21 toward the outer periphery of the bottom portion 20. Furthermore, the outflow guidance portion 21f uses the second protrusion 21f2 to guide the water flowing out of the opening 21c through the first hole 21 toward the outer periphery of the bottom portion 20 indicated by arrow A1, along the slope of the back surface 20d.

[0060] Figure 6A is a side cross-sectional view showing an example of a lid in another embodiment, and Figure 6B is a view of the back surface showing an example of a lid in another embodiment. In the lid 1D shown in Figures 6A and 6B, the bottom 20 of the lower lid 2D has a shape that is convex upward from the outer circumference 20a toward the center O1. The lower lid 2D is an example of a lid, and the surface 20c of the bottom 20 is composed of a slope in which the vertical height decreases from the top 20b toward the outer circumference 20a. In addition, the back surface 20d of the bottom 20 of the lower lid 2D follows the surface 20c and is composed of a slope in which the vertical height decreases from the top 20b toward the outer circumference 20a.

[0066] Figure 8A is a side cross-sectional view showing an example of a lid in another embodiment, and Figure 8B is a view of the back surface showing an example of a lid in another embodiment. The lid 1F shown in Figures 8A and 8B has the same configuration as lid 1A, except that the bottom 20 of the lower lid 2F does not have a third hole.

[0067] Figure 9A is a side cross-sectional view showing an example of a lid in another embodiment, and Figure 9B is a perspective view showing an example of a lid in another embodiment. In the lid 1G shown in Figures 9A and 9B, the bottom 20 of the lower lid 2G has a corrugated shape that is concentric with respect to the center O1. The lower lid 2G is an example of a lid, and the surface 20c of the bottom 20 is composed of a corrugated surface in which parts that are higher in the vertical direction and parts that are lower are arranged alternately. In addition, the back surface 20d of the bottom 20 of the lower lid 2G follows the surface 20c and is composed of a corrugated surface in which parts that are higher in the vertical direction and parts that are lower are arranged alternately.

[0068] The lower cover portion 2G is provided with a first hole 21, a second hole 22, and a fourth hole 25 in its bottom portion 20. The second hole 22 has the same configuration as the cover portion 1A. The first hole 21 is provided in the bottom portion 20 of the lower cover portion 2G at a point where the vertical height is higher, which is the peak of the corrugated surface. The fourth hole 25 is provided in the bottom portion 20 of the lower cover portion 2G at a point where the vertical height is lower, which is the bottom of the corrugated surface.

[0069] The lower cover portion 2G is equipped with a guide portion 20g1 that guides water that has passed through the first hole portion 21 along the back surface 20d of the bottom portion 20. The guide portion 20g1 is composed of a slope between a portion where the vertical height is higher, which is the apex of the corrugated surface, and a portion where the vertical height is lower, which is the bottom of the corrugated surface.

[0070] In the lid portion 1G, water passing through the first hole 21 of the lower lid portion 2G flows along the back surface 20d of the bottom portion 20 of the lower lid portion 2G, from the part where the vertical height is higher, which is the apex of the corrugated surface, to the part where the vertical height is lower, which is the bottom of the corrugated surface, due to the slope that constitutes the guide portion 20g1.

[0071] As a result, food waste adhering to the underside 20d of the bottom 20 flows from the part with a higher vertical height, which is the top of the corrugated surface, to the part with a lower vertical height, which is the bottom of the corrugated surface. Then, the lid 1G allows the food waste that has flowed to the part with a lower vertical height, which is the bottom of the corrugated surface, to fall into the crushing chamber 101 by water passing through the fourth hole 25 of the lower lid 2G.

[0072] Figure 10A is a side cross-sectional view showing an example of a lid in another embodiment, and Figure 10B is a perspective view showing an example of a lid in another embodiment. In the lid 1H shown in Figures 10A and 10B, the bottom 20 of the lower lid 2H has a shape that is concentrically wavy with respect to the center O1. The lower lid 2H is an example of a lid, and the surface 20c of the bottom 20 is composed of a wavy surface in which parts that are higher in the vertical direction and parts that are lower are arranged alternately. In addition, the back surface 20d of the bottom 20 of the lower lid 2H follows the surface 20c and is composed of a wavy surface in which parts that are higher in the vertical direction and parts that are lower are arranged alternately.

[0073] The lower cover portion 2H is provided with a first hole 21 and a second hole 22 in its bottom portion 20. The second hole 22 has the same configuration as the cover portion 1A. The first hole 21 is provided in the bottom portion 20 of the lower cover portion 2H at a point where the vertical height is higher, which is the peak of the corrugated surface. The first hole 21 is arc-shaped, and the arc length of the first hole 21 located radially outside the bottom portion 20 is longer than that of the first hole 21 located radially inside the bottom portion 20. The first holes 21 are arranged radially.

[0074] The lower cover portion 2H includes a curved portion 20h that guides the water that has passed through the first hole portion 21 along the back surface 20d of the bottom portion 20. The curved portion 20h is an example of a guide portion and is composed of a slope between a portion where the vertical height is higher, which is the apex of the corrugated surface, and a portion where the vertical height is lower, which is the bottom of the corrugated surface, on the bottom portion 20 of the lower cover portion 2H.

[0075] In the lid portion 1H, water passing through the first hole 21 of the lower lid portion 2H flows along the back surface 20d of the bottom portion 20 of the lower lid portion 2H, from the part where the vertical height is higher, which is the apex of the corrugated surface, to the part where the vertical height is lower, which is the bottom of the corrugated surface, due to the slope that constitutes the curved surface portion 20h of the bottom portion 2H. In addition, the corrugated surface of the back surface 20d of the bottom portion 20 causes the water passing through the first hole 21 to flow in the circumferential direction of the bottom portion 20.

[0076] As a result, the food waste adhering to the underside 20d of the bottom 20 flows from the part with a higher vertical height, which is the top of the corrugated surface, to the part with a lower vertical height, which is the bottom of the corrugated surface, and falls into the crushing chamber 101.

[0077] Figure 11A is a side cross-sectional view showing an example of a lid in another embodiment, and Figure 11B is a perspective view showing an example of a lid in another embodiment. In the lid 1J shown in Figures 11A and 11B, the bottom 20 of the lower lid 2J has a shape that is concentrically wavy with respect to the center O1. The lower lid 2J is an example of a lid, and the surface 20c of the bottom 20 is composed of a wavy surface in which parts that are higher in the vertical direction and parts that are lower are arranged alternately. In addition, the back surface 20d of the bottom 20 of the lower lid 2J follows the surface 20c and is composed of a wavy surface in which parts that are higher in the vertical direction and parts that are lower are arranged alternately.

[0078] The lower cover portion 2J is provided with a first hole 21 and a second hole 22 in its bottom portion 20. The second hole 22 has the same configuration as the cover portion 1A. The first hole 21 is provided in the bottom portion 20 of the lower cover portion 2J at the point where the vertical height is higher, which is the peak of the corrugated surface. The first hole 21 is arc-shaped, and the arc length of the first hole 21 located on the radially outer side of the bottom portion 20 is longer than that of the first hole 21 located on the radially inner side of the bottom portion 20. In addition, the first holes 21 are arranged radially, with one row between each other in the radial direction of the bottom portion 20, and their positions are shifted in the circumferential direction of the bottom portion 20.

[0079] The lower cover portion 2J includes a curved portion 20j that guides the water that has passed through the first hole portion 21 along the back surface 20d of the bottom portion 20. The curved portion 20j is an example of a guide portion and is composed of a slope between a portion where the vertical height is higher, which is the apex of the corrugated surface, and a portion where the vertical height is lower, which is the bottom of the corrugated surface.

[0080] In the lid portion 1J, water passing through the first hole 21 of the lower lid portion 2J flows along the back surface 20d of the bottom portion 20 of the lower lid portion 2J, from the part where the vertical height is higher, which is the apex of the corrugated surface, to the part where the vertical height is lower, which is the bottom of the corrugated surface, due to the slope that constitutes the curved surface portion 20j. In addition, the corrugated surface of the back surface 20d of the bottom portion 20 causes the water passing through the first hole 21 to flow in the circumferential direction of the bottom portion 20.

[0081] As a result, the food waste adhering to the underside 20d of the bottom 20 flows from the part with a higher vertical height, which is the top of the corrugated surface, to the part with a lower vertical height, which is the bottom of the corrugated surface, and falls into the crushing chamber 101.

[0082] Figure 12A is a side cross-sectional view showing an example of a lid in another embodiment, and Figure 12B is a perspective view showing an example of a lid in another embodiment. In the lid 1K shown in Figures 12A and 12B, the bottom 20 of the lower lid 2K has a shape that is convex upward from the outer circumference 20a toward the center O1. The lower lid 2K is an example of a lid, and the surface 20c of the bottom 20 is composed of a slope in which the height in the vertical direction decreases from the top 20b toward the outer circumference 20a. In addition, the back surface 20d of the bottom 20 of the lower lid 2K is composed of a substantially horizontal surface perpendicular to the vertical direction from the top 20b toward the outer circumference 20a.

[0083] The lower cover portion 2K is provided with a first hole 21, a second hole 22, and a third hole 24 in the bottom portion 20. The first hole 21, the second hole 22, and the third hole 24 have the same configuration as the cover portion 1A. The first hole 21 is provided at multiple locations along the radial direction of the bottom portion 20, extending from the top portion 20b toward the outer circumference 20a. The first hole 21 is arc-shaped, and the arc length of the first hole 21 located on the radially outer side of the bottom portion 20 is longer than that of the first hole 21 located on the radially inner side of the bottom portion 20. The first holes 21 are arranged radially.

[0084] On the lower cover portion 2K, a recess is formed on the back surface 20d of the bottom portion 20 where the first hole 21 is provided, which is connected to the circumferential direction of the bottom portion 20, and this recess constitutes the guide portion 21k.

[0085] In the lid portion 1K, water passing through the first hole 21 of the lower lid portion 2K flows in the circumferential direction of the bottom portion 20 due to the uneven shape of the underside 20d of the bottom portion 20. As a result, food waste adhering to the underside 20d of the bottom portion 20 falls into the crushing chamber 101. [Explanation of Symbols]
