[0021] A sink unit S and a hand-washing unit W according to one embodiment of the present invention will be described. First, a kitchen K equipped with a cooking appliance 12 including the sink unit S will be described. For ease of explanation, the up-down direction, the longitudinal direction, and the lateral direction will be described based on the directions shown in FIG.

[0022] 1, a kitchen K includes a table 11 and a cooking appliance 12 placed on the table 11, and a space for an operator to work is formed around the table 11. Such a kitchen K is one area of ​​a building (e.g., a house).

[0023] 1 and 2, the table 11 is a table including a top plate 13 and a plurality of legs 14 extending downward from the top plate 13. The table 11 of this embodiment is a table independent of the building and can be freely moved relative to the building. Furthermore, the entire periphery of the table 11 in the horizontal direction is a working position where an operator can work with the placed cooking appliance 12.

[0024] The top plate 13 has an upper surface serving as an installation surface 11a that extends in the longitudinal and lateral directions, and is a plate-like body with a thickness that matches the vertical direction; in this embodiment, it is a rectangular plate. The top plate 13 is a plate without holes that penetrate in the vertical direction, and the installation surface 11a is configured to be flat. The longitudinal length of the top plate 13 is longer than the longitudinal length of the functional unit 2 described below; specifically, it is at least twice the longitudinal length of the functional unit 2, and in this embodiment, it is at least 2.5 times the length. This configuration allows multiple functional units 2 to be arranged side by side on the top plate 13. The lateral length of the top plate 13 is also longer than the lateral length of the functional unit 2, and in this embodiment, it is longer than the longitudinal length of the functional unit 2.

[0025] The legs 14 are rod-shaped bodies extending downward from the top plate 13, and support the top plate 13 while keeping it spaced apart from the floor surface of the building. In this embodiment, the legs 14 are disposed at the four corners of the top plate 13. Such legs 14 are independent of the building.

[0026] The cooking appliance 12 is an appliance used for cooking. In this description, cooking refers to the general preparation of food and drink, including, for example, processing ingredients and washing dishes. The cooking appliance 12 includes multiple functional units 2 with cooking functions. The cooking appliance 12 of this embodiment includes four functional units 2, each with a different cooking function. That is, the cooking appliance 12 of this embodiment includes two or more types of functional units 2. As shown in FIG. 1, the cooking appliance 12 includes a worktop unit 5 that functions as a worktop for cooking, a sink unit S that functions as a sink for cooking, and a heating unit 8 that functions to heat food for cooking. The cooking appliance 12 also includes a storage unit 9, as shown in FIGS. 11 and 12, that can store small items for cooking (such as knives and other cooking utensils) and small items for eating (such as tableware). The cooking appliance 12 preferably includes at least one of the sink unit S and the heating unit 8 for cooking. Furthermore, the cooking appliance 12 is configured to be liftable and portable. Specifically, the weight of each functional unit 2 is 20 kg or less, and the size of each functional unit 2 is small enough that a person can lift and move it (the total length of the three sides (the vertical length, the short side length, and the long side length) is 180 cm or less).

[0027] As shown in Figures 3 to 5, each functional unit 2 includes an outer frame 3 and a functional part 4. The functional part 4 is a part that performs the function of cooking, and the outer frame 3 is a frame body that houses the functional part 4. In each functional unit 2, the outer frame 3 has a common shape, and the functional part 4 has a different configuration depending on the function that each functional unit 2 performs.

[0028] Each functional unit 2 also includes a first side surface portion A1 and a second side surface portion B1 different from the first side surface portion A1. In this embodiment, the second side surface portion B1 includes a side surface facing the first side surface portion A1 in the short direction and a side surface intersecting the first side surface portion A1, and both a worker facing the first side surface portion A1 and a worker facing the second side surface portion B1 can use the functional unit 2 to work.

[0029] As shown in FIGS. 3 to 5 , the outer frame 3 is box-shaped and open at the top. Specifically, the outer frame 3 includes a bottom 31 that forms the bottom, side wall 32 that forms the side, and frame connectors 33 that connect the outer edge of the bottom 31 to the lower end of the side wall 32. The outer frame 3 also includes decorative sections 34 disposed on the outer surfaces of the side wall 32 and the frame connector 33. In the outer frame 3 of this embodiment, the bottom 31, side wall 32, and frame connector 33 are integrally formed, and the decorative sections 34 are attached to the outer surface. The outer frame 3 is configured so that the functional section 4 can be fitted onto it from above. The outer frame 3 is configured to be large enough for a person to lift and move it; specifically, the total length of its three sides (the sum of the vertical, lateral, and longitudinal lengths) is 180 cm or less.

[0030] The bottom 31 is a plate-like member having a substantially uniform thickness in the longitudinal and lateral directions, and its lower surface serves as the mounting surface 2a. The mounting surface 2a faces the installation surface 11a when the functional unit 2 is placed on the mounting base 11, and at least a portion of the mounting surface 2a abuts against the installation surface 11a. In this embodiment, the mounting surface 2a is formed flat, and substantially the entire surface abuts against the installation surface 11a.

[0031] The frame connecting portion 33 is a portion that rises upward from the outer edge of the bottom portion 31. Specifically, the frame connecting portion 33 extends outward and upward from the outer edge of the bottom portion 31 relative to the bottom portion 31, and in this embodiment, has a curved shape that convex outward relative to the bottom portion 31. That is, the frame connecting portion 33 extends outward from the bottom portion 31 in a horizontal direction that intersects the up-down direction at a position spaced above the bottom portion 31. Such a frame connecting portion 33 forms a gap between the installation surface 11a and the outer frame portion 3 where a worker can place their fingers, and therefore functions as a finger hook 33a on which a worker lifting the outer frame portion 3 can place their fingers.

[0032] The side wall 32 is a wall extending in the vertical direction and is arranged to surround the bottom 31 in the horizontal direction. Specifically, the side wall 32 is a wall connected to the upper end of the frame connecting portion 33 and extends upward from the frame connecting portion 33. The side wall 32 also has a detachment portion 32a. The detachment portion 32a is a portion where a finger can be hooked to remove the functional portion 4 attached to the outer frame 3 from the outer frame 3, and in this embodiment, is a notch formed in the upper end of the side wall 32 that is concave downward. In other words, with the functional unit 2 of this embodiment, the functional portion 4 fitted to the outer frame 3 can be removed by hooking a finger on the detachment portion 32a.

[0033] The decorative portion 34 is disposed on the outer surface of the outer frame portion 3 excluding the mounting surface 2a. In this embodiment, the decorative portion 34 is a sheet body having a pattern or the like printed on its surface, and is attached to the side wall portion 32 and the frame connecting portion 33 with the surface facing outward.

[0034] 3 and 5, the functional part 4 performs a cooking function while housed in the outer frame part 3. Specifically, the functional part 4 includes a functional fitting part 41 that fits into the outer frame part 3, and a functional main body part 42 that performs a cooking function. The functional main body part 42 has a configuration corresponding to the function of each functional unit 2.

[0035] The functional fitting portion 41 is configured so as to be able to fit into the outer frame portion 3 from above. Specifically, the functional fitting portion 41 includes a accommodated portion 411 that fits inside the outer frame portion 3 and is accommodated therein, and a locking portion 412 that extends horizontally outward from the upper end of the accommodated portion 411. The accommodated portion 411 has a box-like shape in the horizontal direction that corresponds to the shape of the inner surface of the side wall portion 32. The accommodated portion 411 accommodates at least a portion of the functional main body portion 42.

[0036] The locking portion 412 rests on and locks onto the upper end of the side wall portion 32, restricting downward movement of the functional fitting portion 41 relative to the outer frame portion 3. Specifically, the locking portion 412 is configured to extend diagonally upward and outward in the horizontal direction from the upper end of the accommodated portion 411, and the extension distance in the horizontal direction is approximately equal to the thickness of the side wall portion 32. Specifically, the locking portion 412 is provided to extend outward from both ends in the short direction and both ends in the long direction at the upper end of the accommodated portion 411, and in this embodiment, is provided around the entire circumference in the horizontal direction. Furthermore, the locking portion 412 is configured so that the placement surface 2a can fit within the area surrounded by the locking portion 412 in the horizontal direction.

[0037] The locking portion 412 has a lower abutment surface 412a and an upper abutment surface 412b. The lower abutment surface 412a is the lower surface of the locking portion 412 and is the surface that abuts against the upper end of the side wall portion 32. The lower abutment surface 412a is a surface that extends diagonally horizontally outward and upward. The upper abutment surface 412b is the upper surface of the locking portion 412 and is a surface that has a shape corresponding to the lower abutment surface 412a.

[0038] As shown in FIGS. 3 to 5, the workbench unit 5 includes an outer frame portion 3 and a platform function portion 5A as the function portion 4, and is box-shaped as a whole.

[0039] The base function part 5A includes a functional fitting part 41, and a base support part 51 and a base main part 52 as a functional main part 42. The base support part 51 of this embodiment is configured integrally with the functional fitting part 41.

[0040] The base support portion 51 is configured to support the base main body portion 52 from below. Specifically, the base support portion 51 has a support upper surface which is the upper surface of the base support portion 51 (the upper surface of the functional fitting portion 41), and is configured to abut against the lower surface of the base main body portion 52 to support it.

[0041] The table main body 52 is located at the upper end of the work table unit 5, and has an upper surface configured as a substantially flat work surface 52a. In this embodiment, the table main body 52 is a plate-like body and includes a table portion 521 whose upper surface forms the work surface 52a, and a table locking portion 522 arranged around the table portion 521 in the horizontal direction. The table locking portion 522 has a shape corresponding to the locking portion 412, and is configured to extend diagonally outward and upward in the horizontal direction.

[0042] The table main body 52 is placed above the table support portion 51, and the table support portion 51 supports the work surface 52a from below. The table main body 52 includes a table locking portion 522 shaped to correspond to the locking portion 412, so that the lower surface of the table locking portion 522 abuts against and locks onto the upper abutment surface 412b of the locking portion 412. This restricts horizontal movement of the table main body 52, preventing the table main body 52 from shifting even if a horizontal force is applied to the table main body 52 during work. As shown in FIG. 3 , the table main body 52 may also be configured to include a small table 523 that is smaller than the table main body 52 and can be placed on top of the table main body 52. ​​The small table 523, like the table main body 52, may be configured to include a table locking portion 522 on its horizontal outer edge, thereby locking onto the table locking portion 522 of the table main body 52 and restricting horizontal movement.

[0043] 6 to 8, the sink unit S includes an outer frame 3, a sink portion 6 as a functional portion 4, a circulation mechanism 7 as a functional portion 4, and a filter F as a functional portion 4. The sink unit S is box-shaped as a whole. The circulation mechanism 7 and the filter F form a functional main body portion 42.

[0044] The sink 6 includes an outer frame 3 that forms the outer peripheral surface and bottom surface of the sink 6, and a sink main body 61 that is housed inside the outer frame 3. The sink 6 is configured so that the sink main body 61 can receive and store water. In other words, the sink main body 61 is both the functional fitting portion 41 and the functional main body portion 42.

[0045] As shown in Figures 7 and 8, sink body 61 is box-shaped with an open top that can fit into outer frame 3. Specifically, sink body 61 includes sink lower portion 611 and sink side portion 612 that extends upward from the outer edge of sink lower portion 611, forming a receiving space surrounded by sink lower portion 611 and sink side portion 612. Sink body 61 is also configured to receive and store water. Sink body 61 also includes water storage portion 63 located at one end in the longitudinal direction (right side in the figure), and receiving portion 62 located at the other end in the longitudinal direction of water storage portion 63 (left side in the figure). In other words, water storage portion 63 and receiving portion 62 are arranged side by side in the longitudinal direction.

[0046] The sink lower part 611 is a plate-like body extending in a direction intersecting the vertical direction, and its upper surface forms the bottom surface of the receiving space. The sink lower part 611 includes a water storage bottom 613 that forms the bottom surface of the water storage part 63, a receiving bottom 614 that forms the bottom surface of the receiving part 62, and a bottom step 615 located between the water storage bottom 613 and the receiving bottom 614. The water storage bottom 613 is located lower than the receiving bottom 614. In other words, the water storage bottom 613 is a portion that is recessed downward relative to the receiving bottom 614 via the bottom step 615. The receiving bottom 614 is inclined as a whole so that the bottom step 615 side faces downward, and one longitudinal end is connected to the upper end of the bottom step 615. The other longitudinal end of the water storage bottom 613 is connected to the lower end of the bottom step 615, and in this embodiment, it extends from the connecting part so that one longitudinal end faces downward.

[0047] With this configuration, water received by the receiving portion 62 flows along the receiving bottom 614 to the water storage portion 63 and accumulates there. The water storage portion 63 is configured to be able to store a sufficient amount of water for circulation. Specifically, the water storage portion 63 is configured to store a sufficient amount of water so that, when water is continuously circulated, the amount of water discharged per unit time by the circulation mechanism 7 does not decrease due to a decrease in the amount of water in the water storage portion 63. For example, the water storage portion 63 can store 1.5 to 3 times the total amount of water absorbed by the circulation mechanism 7 during the average time it takes for the water to pass through the water circulation path and return to the water storage portion 63. As such, since the water storage portion 63 can store a sufficient amount of water, the sink unit S can be used continuously and comfortably when circulating water. Furthermore, the bottom step portion 615 is located between the receiving bottom 614 and the water storage bottom 613, and this prevents the water accumulated in the water storage portion 63 from flowing back into the receiving portion 62.

[0048] Sink side portion 612 is a wall that extends upward from the outer periphery of receiving bottom portion 614 and water storage bottom portion 613, except for the portion connected to bottom step portion 615. In other words, sink side portion 612 is a wall that surrounds the entire periphery of the lower part of the sink. The upper end of sink side portion 612 is configured so that the vertical height is approximately equal around the periphery. Sink side portion 612 also has a locking portion 412 at its upper end.

[0049] As shown in Figure 6, circulation mechanism 7 includes circulation casing 71, pump 72 disposed inside the casing, and power supply unit 73. Circulation mechanism 7 is disposed inside sink body 61 and is configured to suck up water accumulated in receiving portion 62 and discharge the water into receiving portion 62. Circulation mechanism 7 is separate from sink body 61 and is detachable from sink body 61. Specifically, circulation mechanism 7 is attached to sink body 61 by being disposed inside sink body 61, and can be removed from sink body 61 by removing circulation mechanism 7 from inside sink body 61.

[0050] The circulation casing 71 is box-shaped and can be placed in the water storage section 63, with its longitudinal and lateral dimensions being approximately equal to those of the water storage section 63. The circulation casing 71 has a water intake (not shown) at its lower end and a water discharge port 74 at its upper end, with a water passage 75 extending from the water intake port to the water discharge port 74. The water passage 75 of the circulation casing 71 in this embodiment is configured so that substantially all of the water drawn up by the pump 72 (excluding water droplets adhering to the water passage 75) is discharged from the water discharge port 74. In other words, as will be described later, the circulation casing 71 is not configured to temporarily store and supply water filtered by the filter F, but is configured to supply water immediately after filtration. At least the lower end of the circulation casing 71 in this embodiment is configured to be able to be accommodated in the water storage section 63. The upper surface of the circulation casing 71 is flat. The upper surface of the circulation housing 71 installed on the sink body 61 is located at the same height as the upper end of the sink body 61 (the engaging portion 412 of the sink side portion 612) or lower than the upper end of the sink body 61. Furthermore, the upper surface of the circulation housing 71 can abut against the lower surface of the lid portion 21 that is placed on the sink body 61, which will be described later.

[0051] As shown in Figure 7, the water outlet 74 is a hole formed in the side surface of the circulation casing 71, and is configured to be able to discharge water outward and downward from the side surface of the circulation casing 71. In other words, the water outlet 74 is located below the top surface of the circulation casing 71 and below the upper end of the sink side portion. Specifically, the water outlet 74 is formed in the side surface of the circulation casing 71 on the other longitudinal end side, which is the side surface facing the receiving portion 62. The water outlet 74 is also located in the center of the circulation casing 71 in the short direction.

[0052] As shown in Figure 6, pump 72 is disposed midway through water channel 75 and configured to suck water through the water intake port and deliver the sucked water to water outlet 74. Pump 72 is configured to be able to continuously deliver a constant amount of water to water outlet 74 when driven. Pump 72 in this embodiment is disposed in a position biased to one side in the short direction (the lower side in the figure). Pump 72 can be switched between a driven state and a non-driven state by a switch (not shown) provided in circulation mechanism 7.

[0053] The power supply unit 73 is a power source, and in this embodiment is a battery, that supplies power as a driving source to the pump 72. The power supply unit 73 is disposed at a position away from the water channel 75 inside the circulation housing 71, and is housed at a position where it does not come into contact with the water flowing inside the circulation housing 71.

[0054] As shown in Figure 7, the circulation mechanism 7 of this embodiment is configured so that water discharged from the water outlet 74 splashes outward from the side of the circulation housing 71, and so that the discharged water reaches the receiving bottom 614 without running down a wall or the like.

[0055] As shown in FIG. 6 , the filter F is configured to filter water circulating within the sink body 61 by the circulation mechanism 7. Specifically, the filter F is configured to filter out dust, microorganisms, and the like from the passing water. The filter F is disposed midway along the water circulation path, and in this embodiment, is disposed inside the circulation casing 71. Specifically, the filter F is disposed between the water intake port and the pump 72 in the water channel 75 of the circulation casing 71, and in this embodiment, is disposed below the pump 72. In other words, the filter F filters water just before it is sucked up by the pump 72, and the filtered water is sucked into the pump 72. The filter F is also configured to be detachable from the water channel 75. For example, the filter F that has filtered a specified amount of water can be removed from the water channel 75 and replaced with a new filter F.

[0056] The sink section 6, circulation mechanism 7, and filter F described above circulate the water stored in the sink section 6 while filtering it, allowing the water to be reused repeatedly in the sink unit S. Specifically, when the pump 72 is driven, water stored in the water storage section 63 is sucked up through the water intake port, passes through the filter F and the pump 72, and is discharged from the water outlet 74 into the receiving section 62. The discharged water then flows from the receiving section 62 to the water storage section 63, where it is again stored. This allows the sink to function independently of the piping of the water supply or sewerage system. Furthermore, because the pump 72 is driven by a battery serving as the power supply section 73, no power cord is required to drive the pump 72. This allows the sink to function independently of the power cord.

[0057] 9 and 10, the heating unit 8 includes an outer frame portion 3 and a heating device 81 serving as the functional portion 4. In the heating unit 8, the heating device 81 corresponds to both the functional main body portion 42 and the functional fitting portion 41. That is, in the heating unit 8, the functional main body portion 42 and the functional fitting portion 41 are integrally configured.

[0058] The heating device 81 is a device large enough to be accommodated in the outer frame 3 and is capable of heating a pot or other item placed on its upper surface. The heating device 81 of this embodiment is an electric stove and has a cord (not shown) that can be electrically connected to an outlet provided in the building. The cord extends, for example, from a hole formed in the outer frame 3. Specifically, the heating device 81 has a box-shaped heating frame 82 having a heating area 83 on its upper surface on which the device to be heated (e.g., a pot) is placed, and an electric circuit (not shown) that is accommodated inside the heating frame 82 and heats the device to be heated. The heating frame 82 corresponds to the accommodated portion 411, and a locking portion 412 is provided at the upper end of the heating frame 82.

[0059] 11 and 12, the storage unit 9 includes an outer frame 3, and a storage frame 91 and a storage main body 92 as functional parts 4. The storage frame 91 is a functional fitting part 41 that fits into the outer frame 3, and is also a functional main body 42 that performs the function of movably supporting the storage main body 92, and the storage main body 92 is also a functional main body 42 that has the function of storing small items for cooking and eating.

[0060] The storage frame 91, when fitted into the outer frame 3, comprises a frame body 911, which is a wall extending along the inner periphery of the outer frame 3, rails 912 extending in the longitudinal or lateral direction, and locking portions 412 provided on the outer side of the frame body 911. In this embodiment, the rails 912 are provided so as to extend in the longitudinal direction, and a pair of rails 912 are provided spaced apart in the lateral direction. The lower surface of the storage frame 91 is spaced above the bottom 31 of the outer frame 3. That is, a space is formed between the storage frame 91 and the bottom 31 of the outer frame 3. This space can accommodate, for example, tableware.

[0061] The storage main body 92 is a container that forms a space capable of storing small items. The storage main body 92 includes a rail engagement portion 921 that engages with the rail 912 and a box-shaped small item storage portion 922 that forms a space for storing small items, and is supported as a whole by the rail 912 from below, and is movable in the longitudinal direction along the rail 912. In this embodiment, two storage main bodies 92 are provided spaced apart in the longitudinal direction.

[0062] As shown in FIGS. 8 and 12 , a lid portion 21 is provided on the top of the functional unit 2. The lid portion 21 is a plate-shaped body including a flat-top lid main body 22 and a lid locking portion 23 arranged around the lid main body 22 in the horizontal direction. The lid locking portion 23 has a shape corresponding to the locking portion 412 and is configured to extend diagonally outward and upward in the horizontal direction. For example, when the functional unit 2 is not in use, the lid portion 21 is arranged to cover the top of the functional unit 2. In this case, the lid locking portion 23 locks with the locking portion 412 of the functional fitting portion 41, thereby restricting horizontal movement of the lid portion 21. Providing the lid portion 21 in this manner prevents dirt and other contaminants from adhering to the functional portion 4 and the items stored in the functional portion 4 when the functional unit 2 is not in use. The lid portion 21 can also be arranged to cover the top of other functional units 2, not just the storage unit 9.

[0063] 8, the lid portion 21 arranged on the top of the sink unit S is engaged with the engaging portion 412, and the underside of the lid portion 21 can abut against the top surface of the circulation housing 71, so that the circulation housing 71 can support the lid portion 21 from below. Therefore, when an object is placed on top of the lid portion 21, downward bending of the lid portion 21 can be prevented. Furthermore, in the sink unit S, the circulation mechanism 7 and the filter F can be housed below the upper end (engaging portion 412) of the sink portion 6, so that the lid portion can be installed with the circulation mechanism 7 and the filter F housed therein.

[0064] How to use the cooking appliance 12 described above will now be described.

[0065] When using the cooking appliance 12, the necessary functional units 2 are placed on the table 11 as a preparation step. For example, as shown in FIGS. 1 and 2, when cooking ingredients, the heating unit 8, work table unit 5, and sink unit S are placed to cut, wash, and heat the ingredients. Before or after moving the sink unit S, the sink body 61 is filled with the amount of water necessary for circulation, and the water reservoir 63 is filled with water. For example, when the work table unit 5 is no longer needed, the work table unit 5 can be removed from the table 11 and replaced with the storage unit 9. In this way, the cooking appliance 12 is configured such that each functional unit 2 is independent and can be moved freely without being affected by other functional units 2. After the functional units 2 have been placed, the lid 21 can be removed as needed.

[0066] Next, cooking is performed using each functional unit 2. Here, for example, the position of the functional unit 2 can be changed for cooking convenience. Specifically, as shown in FIG. 1, the heating unit 8, which is located at the first installation position P1 at one end of the table 11 in the longitudinal direction, can be moved to another position, the first other installation position P11, as shown in FIG. 13. Here, the first other installation position P11 shown in FIG. 13 is the second installation position P2 where the sink unit S was located in FIG. 1. The sink unit S, which is located at the second installation position P2 shown in FIG. 1, can be moved to the second other installation position P21 shown in FIG. 13. The second other installation position P21 shown in FIG. 13 is the first installation position P1 where the heating unit 8 was located in FIG. 1. In other words, the installation positions of each functional unit 2 can be freely changed, and the functional units 2 can be repositioned so that their positions are interchangeable. Here, regarding the movement of the sink unit S, by moving the sink unit S with water in the sink portion 6, water can be used both before and after the movement. When moving the functional unit 2 placed on the installation surface 11a, the user can place his / her hand on the finger rest 33a and lift the functional unit 2 relative to the installation surface 11a.

[0067] 14, among the work positions around the table 11, a first worker A positioned at a first work position PA, which is a position facing one of the sides extending in the longitudinal direction of the top plate 13, can manually lift and hand over the functional unit 2 to a second worker B positioned at a second work position PB, which is a position facing the table 11. Here, the functional unit 2 has a first side surface portion A1 and a second side surface portion B1 that face each other in the short side direction, and both the worker facing the first side surface portion A1 and the worker facing the second side surface portion B1 can work using the functional unit 2. Therefore, even if the functional unit 2 is handed over to a worker at a different work position, the functional unit 2 can be used without changing its orientation.

[0068] 15, after cooking is finished, the functional units 2 can be put away. When putting away the functional units 2, another functional unit 2 can be stacked on top of one functional unit 2, either directly or via the lid 21. This prevents the put away functional units 2 from taking up a large area and becoming a nuisance.

[0069] Furthermore, as shown in FIG. 8, in the sink unit S, the circulation mechanism 7 and filter F are housed below the upper end (locking portion 412) of the sink portion 6, which prevents the circulation mechanism 7 or filter F from getting in the way when placing another functional unit 2 on the upper end of the sink portion 6. In this embodiment, the upper surface of the circulation mechanism 7 is flat, so that the other functional unit 2 placed on the upper end of the sink portion 6 can also be supported on the upper surface of the circulation mechanism 7, thereby ensuring reliable support of the placed equipment. Moreover, because the circulation mechanism 7 and filter F are housed below the upper end of the sink portion 6, a lid portion 21 that completely covers the upper surface of the sink unit S can be installed. Therefore, for example, when the sink unit S is not in use, the entire top of the sink unit S can be used as a workbench.

[0070] Furthermore, the sink unit S can be placed on the upper end of another functional unit 2 directly or via the lid 21. A flat placement surface 2a is formed on the bottom of the sink unit S, making the sink unit S stable when placed on the upper end of another functional unit 2.

[0071] As described above, cooking appliance 12 of this embodiment is independent of top plate 13 and table 11 and can function independently. Therefore, compared to conventional cooking appliances 12 that depend on top plate 13, cooking appliance 12 can be provided that is independent and allows the operator to freely change the position of functional unit 2 and use it.

[0072] Furthermore, the cooking appliance 12 of this embodiment is a portable cooking appliance 12 that can be lifted and carried by a person. Therefore, compared to a conventional fixed cooking appliance 12 that is fixed to a top plate 13, it can be used in a variety of places both inside and outside the kitchen K, allowing you to cook in a location that suits your lifestyle.

[0073] Furthermore, the cooking appliance 12 of this embodiment is an aggregated / discrete type cooking appliance 12 in which multiple functional units 2 are independent of one another and can be carried around and assembled or separated. Therefore, compared to a conventional aggregated type cooking appliance 12 in which functions are aggregated and fixed on the top plate 13, the necessary functional units 2 can be assembled or separated according to cooking needs and lifestyle, which increases convenience.

[0074] The present embodiment will be summarized below.

[0075] In the sink unit S of this embodiment, water can be circulated while being filtered within the sink section 6, and the sink section 6 can be lifted by a person and moved to multiple installation positions. Therefore, the positional relationship of the sink unit S can be freely changed while the water remains usable.

[0076] In addition, the sink unit S can be stored so that the circulation mechanism 7 and filter F are lower than the upper end of the sink section 6, and other equipment can be placed on the upper end of the sink section 6, so other equipment can be stacked on top of the sink section 6 when storing or carrying the sink unit S.

[0077] Furthermore, since the sink unit S can be placed with the lower part of the sink section 6 on top of other equipment, the sink unit S can be stacked on top of other equipment when storing or carrying the sink unit S.

[0078] Furthermore, the circulation mechanism 7 is formed with a water outlet 74, which is located below the upper end of the sink section 6. This allows the circulation mechanism 7 to fit snugly within the sink section 6. This makes it possible to prevent the sink unit S from interfering with other components located above the location where the sink unit S is to be installed, for example, making the sink unit S easy to carry and use.

[0079] Furthermore, a plate-shaped lid can be attached to the upper end of the sink 6. Therefore, for example, when the sink 6 is not in use, by attaching a plate to the upper end of the sink 6, the sink 6 can be used as a work table or to place other equipment on it, making the sink unit S easier to use.

[0080] Furthermore, since the filter F is disposed in a position upstream of the pump 72 in the water passage 75 in the circulation mechanism 7, it is possible to filter the water before it is supplied to the pump 72. This prevents dust and other debris from entering the pump 72 and causing malfunctions in the pump 72.

[0081] In the cooking appliance 12 of this embodiment, the functional unit 2 can be lifted by a person and moved to a plurality of installation positions, so that the positional relationship of the functional unit 2 can be freely changed.

[0082] Furthermore, the first unit (for example, the heating unit 8) can be moved from the first installation position P1 to the first other installation position P11, and the second unit (for example, the sink unit S) can be moved from the second installation position P2 to the second other installation position P21. Moreover, the positional relationship between the first unit and the second unit can be swapped.

[0083] Furthermore, since the functional unit 2 can be worked on not only from one side but also from the other side, the functional unit 2 can be handed over from one worker to another without having to worry about the orientation of the functional unit 2. This makes it easy to hand over the functional unit 2.

[0084] Furthermore, the functional unit 2 has a first side surface portion A1 and a second side surface portion B1 that is located at a different position from the first side surface portion A1, and an operator facing either the first side surface portion A1 or the second side surface portion B1 can work using the functional unit 2. Therefore, the functional unit 2 can be placed against a wall or on the edge of a table without having to worry about the orientation of the functional unit 2.

[0085] Furthermore, the functional units 2 can be stacked on top of each other, so that when the functional units 2 are not in use, they can be stored in a stacked state.

[0086] Furthermore, since the shapes of the locking portions 412 and the placement surfaces 2a of the functional units 2 are the same, the functional units 2 can be stacked stably without having to worry about the up-down relationship between them.

[0087] Furthermore, since the outer frame 3 can accommodate other functional parts 4 than the one it accommodates, the functional parts 4 can be replaced with the outer frame 3. This allows the functional parts 4 to be replaced with the outer frame 3 as needed, improving usability. Also, for example, by attaching the functional part 4 to another outer frame 3 having a different pattern on the decorative part 34, the appearance of the functional unit 2 can be easily changed.

[0088] Furthermore, since the outer frames 3 have the same shape, even if a functional unit 4 housed in one outer frame 3 is housed in another outer frame 3, the functional unit 4 can be used in the same manner as before the swap, resulting in good usability. Furthermore, since the outer frames 3 have the same shape, a sense of uniformity can be achieved when the functional units 2 are lined up, resulting in a good appearance when multiple functional units 2 are lined up.

[0089] The above describes an embodiment of the present invention using an example, but the present invention is not limited to the above embodiment, and various modifications can be made within the scope that does not deviate from the gist of the present invention.

[0090] For example, the case where the functional units 2 have four different functions has been described, but the configuration is not limited to this, and the combination of the functional units 2 can be determined arbitrarily, and the configuration can also include multiple functional units 2 having the same functional part 4. For example, the configuration can include multiple heating units 8, and the heating units 8 can be swapped by lifting them up.

[0091] Although the functional units 2 have been described as having the same external shape, they may have different external shapes. For example, the shapes of the mounting surfaces 2a and the engaging portions of the functional units 2 may be the same, but the heights may differ depending on the configuration of the functional parts 4.

[0092] Furthermore, the kitchen K may be configured without the mounting table 11. In such a case, work can be performed on the floor, for example. Even in a configuration with the mounting table 11, the mounting table configuration is not limited to the example shown, and various configurations with an installation surface 11a that is spaced apart from the floor can be used.

[0093] Although the functional part 4 and the outer frame part 3 are separate bodies in the above description, they may be integrated, or even if they are separate bodies, they may be non-detachable. Also, a configuration without the outer frame part 3 is possible.

[0094] Furthermore, the functional unit 2 may be configured to include a temporary fixing means for temporarily fixing the functional unit 2 to the installation surface 11a while it is placed on the installation surface 11a. As the temporary fixing means, for example, a suction cup that adheres to the installation surface 11a or a locking means such as a clamp that can be locked to the top plate 13 can be used.

[0095] Although the above description has been given of a case where each functional unit 2 has one function, the configuration is not limited to this, and each functional unit 2 may have multiple functions. For example, by configuring the platform support portion 51 of the workbench unit 5 to be able to store small items, the functional unit 2 can have both a platform function and a storage function.

[0096] Furthermore, while the outer frame portions 3 of the functional units 2 have been described as having the same shape, they may have different shapes. Even if the outer frame portions 3 have different shapes, as long as the portions that engage with the functional portions 4 (for example, the shape of the upper ends of the side wall portions 32) are the same, the functional portions 4 can be interchanged with respect to the outer frame portions 3. Furthermore, by configuring the outer frame portions 3 to have different shapes, the functional portions 4 can be interchanged with respect to the outer frame portions 3 depending on the cooking situation, improving usability. An example of an embodiment having outer frame portions 3 with different shapes is a configuration including multiple outer frame portions 3 with side wall portions 32 of different heights. By interchangeably positioning the functional portions 4 with respect to the outer frame portions 3 according to differences in height and posture of the operator, the functional portions 4 can be positioned at a height that is easy to use, improving usability.

[0097] Furthermore, with regard to changing the installation position of the functional unit 2, the case where one functional unit 2 as a whole is moved from the first installation position P1 to the first other installation position P11 has been described. However, this is not limiting and only the functional part 4 can be moved. Specifically, the functional part 4 housed in the outer frame part 3 located at the first installation position P1 can be removed from the outer frame part, moved, and housed in the outer frame part 3 located at the first other installation position P11. In this case, if the first other installation position P11 is the second installation position P2 where the other functional unit 2 was installed, the functional part 4 of the other functional unit 2 that was attached to the outer frame part 3 at the second installation position P2 can be removed from the outer frame part 3, and the functional part 4 of the one functional unit 2 can be attached to the outer frame part 3 from which the functional part 4 of the other functional unit 2 was removed.

[0098] Furthermore, although an example has been described in which the sink unit S is used together with other functional units 2, the present invention is not limited to this configuration, and the sink unit S can also be used alone. Even in such a case, the sink unit S can be freely moved independently of the piping, etc., making it easy to use.

[0099] Although the circulation mechanism 7 has been described as being configured such that the pump 72 is driven by a battery, the present invention is not limited to this configuration and may be configured such that the pump 72 is driven by an external power source. Even in this configuration, the sink unit S can be freely moved independently of the countertop, water supply and sewerage pipes, etc., making it easy to use.

[0100] Furthermore, although the configuration in which the filter F filters the water immediately before it is discharged from the water outlet 74 has been described as an example, the present invention is not limited to such a configuration, and the filter F may temporarily store the filtered water and then discharge the stored water. When such a configuration is adopted, it is preferable to add chlorine or the like to the filtered water.

[0101] Furthermore, although the example has been described in which the filter F is placed inside the circulation mechanism 7, the present invention is not limited to such a configuration, and the filter F may be placed anywhere along the water circulation path, and may be placed outside the circulation mechanism 7, or even if the filter F is placed inside the circulation mechanism 7, its position within the water channel 75 may be freely changed.

[0102] Furthermore, although the circulation mechanism 7 has been described as being detachable from the sink 6, it is not limited to such a configuration, and may be fixed to the sink 6 and not detachable. When such a configuration is adopted, it is also possible to configure, for example, that only the filter F or the battery serving as the power supply 73 is replaceable.

[0103] Furthermore, while the configuration in which the water outlet 74 is a hole formed on the side of the circulation mechanism 7 has been described as an example, the configuration is not limited to this. For example, the configuration may include a faucet rising upward from the top surface of the circulation housing 71, with the water outlet 74 formed at the tip of the faucet. In such a configuration, when the sink unit S is not in use, the faucet can be laid down so that the upper end of the circulation mechanism 7 is stored at the same height as the upper end of the sink section 6 or at a position lower than the upper end of the sink section 6. Even with this configuration, for example, when the sink unit S is not in use, other equipment can be placed on the upper end of the sink unit S. Furthermore, when storing the sink unit S, interference between the sink unit S and other components located above the sink unit S (for example, a shelf located above the sink unit S when stored on a shelf) can be suppressed, making the sink unit S easy to carry and store.

[0104] As shown in Figures 6 to 8, the hand-washing unit W has the same configuration as the sink unit S. That is, it is the same as the sink unit S except that it uses the circulating water for hand-washing. Such a hand-washing unit W can be placed, for example, in a bathroom, allowing people to wash their hands with the circulating water. The hand-washing unit W also provides the same effects as the sink unit S. Furthermore, the hand-washing unit W can be stacked on top of other devices (for example, another hand-washing unit W or a functional unit 2 with a function for drying washed hands). For example, the other device can be placed on top of the hand-washing unit W, or the bottom of the hand-washing unit W can be placed on top of the other device.

[0105] Another embodiment of the sink unit S and hand-washing unit W of the present invention will be described with reference to Figures 16 and 17. The same components as those in the above-described embodiment will be given the same reference numerals and will not be described again.

[0106] The sink unit S and hand-washing unit W of this embodiment differ from the above-described embodiments in the configuration of the sink body 61. Specifically, the sink body 61 includes a sink lower portion 611 having a flat upper surface and a bottom plate portion 64 disposed on the upper surface of the sink lower portion 611, and a double bottom is formed by the upper surface of the sink lower portion 611 and the bottom plate portion 64. In addition, in the sink body 61 of this embodiment, the upper surface of the bottom plate portion 64 forms the receiving bottom portion 614, and the upper surface of the sink lower portion 611 forms the water storage bottom portion 613. In other words, the upper side of the bottom plate portion 64 is the receiving portion 62, and the lower side of the bottom plate portion 64 is the water storage portion 63, with the receiving portion 62 and the water storage portion 63 arranged vertically side by side.

[0107] The bottom plate 64 includes a plate-shaped bottom plate main body 641 and a plurality of bottom plate legs 642 connected to the underside of the bottom plate main body 641. The longitudinal and lateral lengths of the bottom plate main body 641 are shorter than the longitudinal and lateral lengths of the sink lower part 611. When installed, a space 64a through which water can flow is formed at least partially between the periphery of the bottom plate main body 641 and the sink side part 612. The top surface of the bottom plate main body 641 is inclined so that the periphery forming the space 64a is positioned downward. The bottom plate 64 is detachable from the sink lower part 611 or the sink side part 612. In this embodiment, the bottom plate legs 642 are attached to the sink lower part 611 by being positioned above the sink lower part 611 so that they are in contact with the upper surface of the sink lower part 611.

[0108] In the sink unit S and hand-washing unit W configured as described above, water discharged from outlet 74 of circulation mechanism 7 is received by receiving bottom 614, which is the upper surface of bottom plate main body 641, flows along bottom plate main body 641, drops from space 64a between sink side portion 612 and bottom plate main body 641, and accumulates in the space between bottom plate main body 641 as water storage portion 63 and water storage bottom 613, which is the upper surface of sink lower portion 611. The water accumulated in water storage portion 63 is then sucked up by circulation mechanism 7, filtered, and discharged again into receiving portion 62. In this way, the water is circulated while being filtered, allowing the sink to function as a sink or for hand-washing independently of water and sewerage pipes.

[0109] Furthermore, in the sink unit S and hand-washing unit W of this embodiment, water can be stored under the bottom plate portion 64, so that water can be stored efficiently even in a small area.

[0110] Furthermore, because bottom plate portion 64 is detachable from sink lower portion 611 or sink side portion 612, water storage portion 63 can be exposed by removing bottom plate portion 64. This makes it easier to perform cleaning and other tasks on water storage portion 63.

[0111] Although the example described above is one in which a space 64a is formed between the sink side portion 612 and the bottom plate portion 64 to allow water to flow from the receiving portion 62 to the water storage portion 63, this is not limited to such a case. For example, a configuration in which no space 64a is formed between the sink side portion 612 and the bottom plate portion 64, and a hole penetrating vertically through the bottom plate portion 64 can be formed, allowing water to fall from the hole and cause the water in the receiving portion 62 to flow into the water storage portion 63, can also be used.

[0112] A reference example will now be described. The sink unit S and hand-washing unit W may be configured without the circulation mechanism 7 and with a sink section 6 connected to the drinking water pipe and the sewerage pipe, with the entire faucet, including the spout 74 connected to the drinking water pipe, positioned below the upper end of the sink section 6. In such a configuration, a plate-shaped member (e.g., lid 21) can be placed to cover the entire upper part of the sink section 6. Therefore, even in the configuration of the reference example, when the sink section 6 is not in use, a plate-shaped member can be placed on top of the sink section 6, allowing work to be done or objects to be placed on the plate-shaped member. Furthermore, the configuration of the reference example may be configured without a faucet, with the spout 74 formed on the sink side section 612. [Explanation of symbols]
