DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] (First embodiment) As shown in FIG. 1, the hand washing unit 10 is installed in a toilet room 2 in which a toilet 4 is installed, for example, in a house, an office, etc. The hand washing unit 10 is fixed to a side wall 100 of the toilet room 2. The side wall 100 of the toilet room 2 refers to a wall that stands on the left and right when a user of the toilet 4 is sitting on the toilet bowl 8 of the toilet 4. In this embodiment, an example is shown in which the hand washing unit 10 is attached to the side wall 100 of the toilet room 2. The hand washing unit 10 may be attached to a wall other than the side wall 100. In this embodiment, the direction in which a user of the hand washing unit 10 faces the hand washing unit 10 is defined as "back", the user side is defined as "front", the right hand side of the user is defined as "right", the left hand side is defined as "left", the upper side is defined as "upper", and the lower side is defined as "lower". The front-to-rear direction when a user of the toilet 4 is sitting on the toilet bowl 8 of the toilet 4 corresponds to the left-to-right direction in this embodiment.

[0008] The hand washing unit 10 is used by a user who has used the toilet 4 in the toilet room 2 to wash his / her hands. The hand washing unit 10 comprises a hand washing unit main body 18, a counter 14, a back panel 12, a paper roll holder 16, a faucet 20, a towel rack member 22, a bracket 24, a water supply pipe 32, and a drain pipe 30.

[0009] 3 and 4, the hand washing unit 10 is assembled by combining one type of hand washing unit 18, one type of counter 14, one type of back panel 12, one type of paper roll holder 16, one type of faucet 20, one type of towel rack member 22, and one type of water supply and drainage pipes 30, 32 according to the user's preferences, construction conditions, etc., from among the assembly sets of the hand washing unit 10 that include multiple types of hand washing unit bodies 18, multiple types of counters 14, multiple types of back panels 12, multiple types of paper roll holders 16, multiple types of faucets 20, and multiple types of water supply and drainage pipes 30, 32. The assembly set of the hand washing unit 10 may include one or more types of mirrors, and the mirror may or may not be selected. Similarly, at least one of the multiple types of hand washing basin main body 18, multiple types of counter 14, multiple types of back panel 12, multiple types of paper roll holders 16, multiple types of faucets 20, and multiple types of water supply and drainage pipes 30, 32 is selected, and the other parts do not have to be selected.

[0010] (Specific configuration of hand washing unit 10) Below, we will explain an exemplary hand-washing unit 10 that is constructed by combining one type of hand-washing unit body 18, one type of counter 14, one type of back panel 12, one type of paper towel holder 16, one type of faucet 20, one type of towel rack member 22, and one type of water supply and drainage pipes 30, 32 from the assembly set of the hand-washing unit 10.

[0011] The hand washing basin body 18 is made of pottery or the like. The hand washing basin body 18 may be made of resin. As shown in FIG. 5, the hand washing basin body 18 has a rectangular shape with two rounded corners on the front side. The hand washing basin body 18 includes a basin portion 18a and a faucet arrangement portion 18c. The faucet arrangement portion 18c is arranged at the right end portion of the hand washing basin body 18. The faucet arrangement portion 18c has a flat upper surface. A faucet 20 is attached to the faucet arrangement portion 18c. The faucet 20 is connected to a water supply pipe 32. The faucet 20 discharges water supplied through the water supply pipe 32. The water discharged from the faucet 20 is received by the basin portion 18a adjacent to the left side of the faucet arrangement portion 18c. The basin portion 18a has a shape that is recessed downward. A drain hole 18b is formed at the lowest position of the basin portion 18a. Water discharged from the faucet 20 is guided into the basin 18a and guided from the drain hole 18b to the drain pipe 30. Water flowing out from the basin 18a is guided through the drain pipe 30 to the sewer.

[0012] As shown in FIG. 10, the hand washing basin body 18 has an inclined surface 18s on the front side that inclines from the bottom to the top in a side view. In the hand washing basin body 18, the upper edge 18e of the inclined surface 18s is located at the most front side. The basin portion 18a of the hand washing basin body 18 requires a minimum dimension at the upper end side to function as a catcher of splashed water droplets when a user washes his / her hands. By arranging the inclined surface 18s on the hand washing basin body 18, the dimensions of the hand washing basin body 18 can be reduced while ensuring the dimensions of the upper end side of the basin portion 18a. This can reduce the sense of oppression felt by users of the toilet room 2.

[0013] The hand washing basin body 18 is fixed to the side wall 100 via a bracket 24. The bracket 24 is fixed to the bottom surface of the hand washing basin body 18. The bracket 24 is made of metal such as stainless steel. As shown in FIG. 7, the bracket 24 includes a flat plate portion 24c attached to the bottom surface of the hand washing basin body 18, a flat plate-shaped mounting portion 24a extending vertically downward from the rear edge of the flat plate portion 24c, and a reinforcing portion 24b for maintaining the positional relationship between the flat plate portion 24c and the mounting portion 24a. The reinforcing portion 24b has a flat plate shape perpendicular to each of the flat plate portion 24c and the mounting portion 24a. The flat plate portion 24c is fixed to the hand washing basin body 18 by being sandwiched between the hand washing basin body 18 and the nut 24d by tightening the nut 24d to the screw portion 18d extending downward from the drain hole 18b of the hand washing basin body 18. The mounting portion 24a is fixed to the side wall 100 via a fastener such as a screw.

[0014] The towel hanging member 22 is fixed to the bracket 24. As shown in FIG. 8, the towel hanging member 22 includes a towel hanging bar 22a and a pair of mounting parts 22b. The towel hanging bar 22a is composed of an extension part 22d and a support part 22e, as will be described in detail later. Each of the pair of mounting parts 22b is disposed below the hand washing device main body 18 and is fixed to the bracket 24. The pair of mounting parts 22b have the same configuration as each other. The mounting part 22b is disposed on the back side of the front end of the bracket 24. The mounting part 22b extends toward the back side. As shown in FIG. 9, the mounting part 22b has a cylindrical opening inside. The towel hanging bar 22a is inserted into the opening of the mounting part 22b. The back end of the towel hanging bar 22a is attached to the mounting part 22b by a screw 22c.

[0015] As shown in FIG. 10, the towel hanging bar 22a has an extension 22d that extends from the front end of each of the pair of mounting parts 22b beyond the front lower end of the hand washing basin main body 18 to the front side. The extension 22d of the towel hanging bar 22a curves upward nearer than the front lower end of the hand washing basin main body 18 and extends to the support part 22e. The towel hanging bar 22a curves upward by an angle β with respect to the horizontal plane. The angle β is approximately equal to the angle α of the inclined surface 18s with respect to the horizontal plane. When the angle β is within a range of ±5 degrees with respect to the angle α, it can be said that the angle β is approximately equal to the angle α. By aligning the angle between the inclined surface 18s and the towel hanging bar 22a, the appearance can be improved. The angle β may be 0 degrees or more with respect to the horizontal direction, or may be less than the angle α. By setting the angle β to be equal to or smaller than the angle α, it is possible to avoid a situation in which the gap between the towel hanging bar 22a and the inclined surface 18s becomes too small, making it difficult to hang a towel.

[0016] 1, towel hanging bar 22a includes support portion 22e that extends horizontally in the left-right direction on the front side of inclined surface 18s of hand washing basin main body 18. Towel hanging bar 22a can support a towel hung on support portion 22e.

[0017] The counter 14 is disposed on the left side of the hand washing basin main body 18. The counter 14 has a flat plate shape. The counter 14 is made of resin. The counter 14 may be made of ceramic. The counter 14 has a flat upper surface. In a modified example, the counter 14 may have a recess in which a bottle of hand soap, soap, etc. can be placed. The counter 14 can hold soap for hand washing, etc., to be used when using the hand washing basin unit 10. The user's belongings, such as a mobile terminal, may be placed on the counter 14. As shown in FIG. 5, the counter 14 has a rectangular shape with a rounded corner at the end opposite the hand washing basin main body 18, i.e., the front left side.

[0018] The counter 14 is disposed on the left edge of the hand washing basin body 18 with caulking between them. The counter 14 and the hand washing basin body 18 are positioned by the right edge 14f of the counter 14 and the left edge 18f of the hand washing basin body 18 facing each other. The right edge 14f of the counter 14 and the left edge 18f of the hand washing basin body 18 can each be called a positioning portion. In the left-right direction, the length L2 of the counter 14 is shorter than the length L3 of the hand washing basin body 18. In the left-right direction, the length L2 of the counter 14 may be shorter than the length L3' of the basin portion 18a. The left-right direction can be called the front-rear direction when viewed from a user using the toilet 4. As shown in FIG. 1, the counter 14 is disposed so that the upper edge 14h of the counter 14 is aligned at the same height as the upper edge 18h of the hand washing basin body 18.

[0019] A back panel 12 is disposed above the counter 14. The back panel 12 extends from above the counter 14 to above the hand washing basin body 18. The length of the back panel 12 in the left-right direction is equal to the sum of the length L2 and the length L3. The back panel 12 has a rectangular shape when viewed from the front. The back panel 12 is attached to the side wall 100. The back panel 12 includes a main body portion 12a fixed to the side wall 100 and a panel portion 12b removably fitted into the main body portion 12a. The main body portion 12a includes a frame along the edge of the panel portion 12b. The main body portion 12a is disposed between the upper end edge 14h on the back side of the counter 14 and the upper end edge 18h on the back side of the hand washing basin body 18, with caulking sandwiched between them. The main body 12a is positioned relative to the counter 14 and the hand-washing basin body 18 by placing the lower edge 12c on the upper edge 14h of the counter 14 and the upper edge 18h of the hand-washing basin body 18. The lower edge 12c of the main body 12a, the upper edge 14h of the counter 14, and the upper edge 18h of the hand-washing basin body 18 can each be called a positioning portion. The panel portion 12b has a rectangular flat plate shape. The panel portion 12b is attached to the main body 12a by engaging with the frame of the main body 12a. The back panel 12 can be replaced by fixing the main body 12a to the side wall 100 and replacing the panel portion 12b.

[0020] A paper roll holder 16 is disposed on the underside of the counter 14. The paper roll holder 16 is fixed to the underside of the counter 14 via a screw. As shown in FIG. 6, the paper roll holder 16 includes a cover 16a and a support bar 16b. The support bar 16b has a rectangular frame shape with the toilet 4 side open. The support bar 16b extends to the right from the underside of the counter 14, curves downward at the right end and extends downward, and curves left at the bottom end and extends left. The support bar 16b is open on the toilet 4 side and has a gap that allows the roll paper to be inserted from the left side. The right end of the support bar 16b is closed and configured to prevent the roll paper from falling. This allows the roll paper to be set in the paper roll holder 16 even if the distance between the paper roll holder 16 and the hand washing basin main body 18 is short.

[0021] The cover portion 16a is arranged on the support bar 16b so as to be able to swing. The cover portion 16a covers the roll paper attached to the support bar 16b.

[0022] As shown in Fig. 6, in the paper roll holder 16, the lower edge 16e of the cover portion 16a is located at the front side. In the counter 14, the edge 14e is located at the front side. In the hand washing device main body 18, the upper edge 18e is located at the front side. Comparing the maximum projection dimension L4 from the side wall 100 of the paper roll holder 16, i.e., the distance L4 between the side wall 100 and the lower edge 16e, the maximum projection dimension L5 from the side wall 100 of the counter 14, i.e., the distance L5 between the side wall 100 and the edge 14e, and the maximum projection dimension L6 from the side wall 100 of the hand washing device main body 18, i.e., the distance L6 between the side wall 100 and the upper edge 18e, the maximum dimension L6 is the longest, followed by the maximum projection dimension L4 and the maximum projection dimension L5 in that order.

[0023] As shown in Figures 3 and 4, the hand-washing basin unit 10 is constructed by assembling components selected from multiple types of hand-washing basin bodies 18, multiple types of counters 14, multiple types of back panels 12, multiple types of paper roll holders 16, multiple types of faucets 20, multiple types of water supply and drainage pipes 30, 32, and multiple types of mirrors that can be selectively installed.

[0024] The hand washing machine body 18 shown in FIG. 3 is prepared in a type in which the faucet arrangement section 18c is arranged on the right side of the basin section 18a, and a type in which the faucet arrangement section 18c is arranged on the left side of the basin section 18a. The hand washing machine body 18 may also be prepared in a type in which at least one dimension of the basin section 18a and the faucet arrangement section 18c is different from the dimension of the hand washing machine body 18 shown in FIG. The counter 14 is prepared in a type having a right edge 14f positioned relative to the left edge 18f of the hand washing machine body 18, and a type having a left edge positioned relative to the right edge of the hand washing machine body 18. As shown in FIG. 11, by selecting a type of counter 14 having a left edge positioned relative to the right edge of the hand washing machine body 18, a configuration in which the toilet 4 is arranged on the right side of the hand washing machine unit 10 can be adopted.

[0025] The back panel 12 is prepared in a number of different types with different tile colors. Furthermore, one or more types of the back panel 12 may be prepared with different designs of the panel portion 12b. This allows the back panel 12 to be selected according to the design of the toilet room 2. The back panel 12 may be prepared in a number of types with different lengths in the left-right direction. In this configuration, it is also possible to select whether the back panel 12 is placed on the counter 14 or on the hand-washing basin main body 18. The back panel 12 may be selectable only for the panel portion 12b.

[0026] Each of the multiple types of hand washing basin main bodies 18 has a positioning portion that can be positioned relative to each of the multiple types of counters 14 and the multiple types of back panels 12. Each of the multiple types of counters 14 has a positioning portion that can be positioned relative to each of the multiple types of hand washing basin main bodies 18 and the multiple types of back panels 12. Each of the multiple types of back panels 12 has a positioning portion that can be positioned relative to each of the multiple types of hand washing basin main bodies 18 and the multiple types of counters 14. With this configuration, the hand washing basin main body 18, the counter 14, and the back panel 12 can be appropriately positioned regardless of which combination is selected among the multiple types of hand washing basin main bodies 18, the multiple types of counters 14, and the multiple types of back panels 12. In a modified example, at least one of the multiple types of hand washing basin main bodies 18, the multiple types of counters 14, and the multiple types of back panels 12 may not have a positioning portion.

[0027] As shown in FIG. 4, the paper roll holder 16 is prepared in two types: one in which the support bar 16b allows the roll paper to be inserted from the left end, and one in which the support bar 16b allows the roll paper to be inserted from the right end. The paper roll holder 16 may be prepared in two types, one in which the cover portion 16a is provided, and one in which the cover portion 16a is not provided. Instead of these exemplified types of paper roll holders 16, paper roll holders 16 of different shapes and structures may be provided. In addition to these exemplified types of paper roll holders 16, paper roll holders 16 of different shapes and structures may be provided. Regarding the water supply and drainage pipes 30, 32, a type in which both the water supply and drainage pipes 30, 32 extend from the floor of the toilet room 2, a type in which both the water supply and drainage pipes 30, 32 extend from the side wall 100, and a type in which one of the water supply and drainage pipes 30, 32 extends from the floor of the toilet room 2 and the other extends from the side wall 100 are provided. The faucets 20 are available in three types: one with a water inlet extending to the left, one with a water inlet extending to the right, and one with a different water inlet.

[0028] (The relative position of the hand washing unit and the toilet) The toilet 4 arranged in the toilet room 2 includes a toilet cover 6 and a toilet bowl 8. As shown in FIG. 5, the toilet bowl 8 has a drain hole 8a. The drain hole 8a refers to the part of the toilet bowl 8 downstream of the water surface when the sealing water is normally collected. The hand washing unit 10 is located on the left hand of the user when sitting on the toilet 4. The left edge 14g of the counter 14, i.e., the edge 14g on the toilet 4 side, is located to the right of the drain hole 8a, i.e., in front of the user when sitting on the toilet 4. The left edge 14g may be located to the right of the half position in the front-to-rear direction of the toilet bowl 8. This configuration relieves the feeling of pressure felt by the hand washing unit 10 by the user sitting on the toilet 4. If the edge 14g on the toilet 4 side of the hand washing unit 10 extends to a position overlapping with the drain hole 8a of the toilet bowl 8, the counter 14 is placed around the arm of the user sitting on the toilet 4. In particular, as shown in Fig. 2, when the width of the toilet room 2 is narrow, the movement of the user is restricted by the counter 14. According to the above configuration, it is possible to prevent the hand washing unit 10 from restricting the movement of the user.

[0029] The left edge 14g is located to the right of the end 8e of the toilet bowl 8 on the hand-washing unit 10 side. In this hand-washing unit 10, when the hand-washing unit 10 is viewed from the front, the counter 14 does not extend to a position above the toilet 4. In other words, the counter 14 configured in this way does not extend to a position where it would come into contact with a user sitting on the toilet 4. The hand-washing unit 10 significantly reduces the sense of pressure that a user sitting on the toilet 4 feels from the hand-washing unit 10.

[0030] The same applies to the case where the hand washing unit 10 shown in FIG. 11 is positioned to the right of the user while sitting on the toilet 4.

[0031] As shown in Fig. 3, regardless of which combination of multiple types of hand-washing basin main bodies 18 and multiple types of counters 14 is selected, at least the left edge 14g of the counter 14 is located to the right of the drain hole 8a. In a modified example, among the multiple types of hand-washing basin main bodies 18 and multiple types of counters 14, a type of hand-washing basin main body 18 and counter 14 may be prepared in which the left edge 14g of the counter 14 is located to the left of the drain hole 8a.

[0032] (How to attach the paper roll holder to the counter) As shown in FIG. 12, the bottom surface of the counter 14 is provided with multiple mounting parts 14a, 14b, and 14c. The multiple mounting parts 14a, 14b, and 14c have the same shape. Each mounting part 14a, 14b, and 14c has four screw holes. As shown in FIG. 4, the paper roll holder 16 has four screw holes 16d at the top end corresponding to each mounting part 14a, 14b, and 14c. The paper roll holder 16 is attached to any one of the multiple mounting parts 14a, 14b, and 14c via screws. With this configuration, the left-right position of the paper roll holder 16 can be adjusted according to the positional relationship between the toilet 4 and the hand washing unit 10. As a result, the paper roll holder 16 can be attached to a position where the user can smoothly remove the roll of paper placed in the paper roll holder 16. Of the multiple types of counters 14 shown in FIG. 3, two or more types of counters 14 may have multiple mounting parts 14a, 14b, and 14c.

[0033] In a modified example, as shown in Fig. 4, the paper roll holder 16 may have a plurality of screw hole sets, with four screw holes 16d as one set. The paper roll holder 16 may be attached by aligning the four screw holes 16d of one of the plurality of screw hole sets with one of the plurality of attachment portions 14a, 14b, 14c of the counter 14. In this case, the counter 14 may have the plurality of attachment portions 14a, 14b, 14c, or may have one attachment portion 14a.

[0034] (effect) Since the hand-washing unit 10 does not have a cabinet provided below the hand-washing unit 18, the space below the hand-washing unit 18 is open to the toilet room 2. Compared to when a cabinet is provided below the hand-washing unit 18, the sense of oppression felt by the user from the hand-washing unit 10 is alleviated. In particular, when the toilet room 2 is a narrow space, the sense of oppression can be reduced.

[0035] In the hand washing unit 10, the back panel 12 covers at least a portion of the side wall 100 of the toilet room 2 located above the counter 14. This prevents the side wall 100 located above the counter 14 from being wetted. The back panel 12 may be located above the counter 14 from one end to the other end of the counter 14 in the front-to-rear direction of the toilet room 2, that is, corresponding to the entire left-to-right direction of the counter 14. In other words, since the back panel 12 is located in a range where water is expected to be wetted, it can be said that the counter 14 is short enough to fit within the range where water is expected to be wetted. Since the hand washing unit 10 has a short counter 14 and a compact overall configuration, the sense of pressure felt by the user from the hand washing unit 10 is alleviated.

[0036] The back panel 12 is disposed above the hand-washing basin main body 18. This prevents the side wall 100 located above the hand-washing basin main body 18 from being wetted. The back panel 12 does not have to be disposed over the entire left-right direction of the hand-washing basin main body 18. In this case, the back panel 12 may be disposed at least above the basin portion 18a, or may be disposed around the faucet 20.

[0037] The paper roll holder 16 is disposed below the counter 14. This allows the paper roll holder 16 to be disposed without increasing the left-right dimension of the hand-washing unit 10. This allows the paper roll holder 16 to be disposed while keeping the hand-washing unit 10 compact.

[0038] Comparing the maximum projection dimension L4 of the paper roll holder 16 from the side wall 100, the maximum projection dimension L5 of the counter 14 from the side wall 100, and the maximum projection dimension L6 of the hand washing unit 18 from the side wall 100, the maximum projection dimension L6 is the longest, followed by the maximum projection dimension L5 and the maximum projection dimension L4. The hand washing unit 18 ensures a minimum dimension to function as a catcher for splashing water droplets when a user washes their hands. By making the maximum projection dimension L4 of the paper roll holder 16 and the maximum projection dimension L5 of the counter 14 smaller than the maximum projection dimension L6 of the hand washing unit 18, the hand washing unit 10 can be made smaller and the sense of oppression can be alleviated.

[0039] The left-right length L2 of the counter 14 is shorter than the left-right length L3 of the hand-washing basin main body 18. While ensuring the dimensions of the hand-washing basin main body 18, the hand-washing basin unit 10 can be made smaller, and the feeling of oppression can be alleviated.

[0040] The towel rack member 22 is attached to a bracket 24 below the hand-washing unit 18 by an attachment portion 22b disposed below the hand-washing unit 18. The attachment portion 22b for attaching the towel rack member 22 does not need to be disposed on the front, left or right side, or top of the hand-washing unit 18. This makes it possible to make the hand-washing unit 10 smaller and reduce the feeling of oppression.

[0041] The towel hanging bar 22a of the towel hanging member 22 has a support portion 22e that extends horizontally in the left-right direction on the front side of the inclined surface 18s of the hand washing basin main body 18. When a towel is hung on the support portion 22e, the towel is positioned on the front side of the water supply and drainage pipes 30, 32.
