Description

[0001] The invention relates to a sanitary basin, in particular a sink, with a basin base, with at least one basin wall which is essentially vertical or steep relative to the basin base, with a drain opening which is provided with a drain valve and with an overflow.

[0002] Sanitary basins such as washbasins and sinks are available in a wide variety of designs. These basins are typically made of stainless steel, plastic, ceramic, or composite materials.

[0003] With conventional washbasins and sinks, the drain and overflow are directly visible. Dirt, such as food scraps, and deposits, such as grime, are immediately visible and unsightly at the drain and overflow. The drain and overflow of conventional washbasins and sinks are generally difficult or time-consuming to keep clean. Another problem with conventional washbasins and sinks is that the drain valve can be obstructed by objects placed over it, such as dishes. Such a malfunction of the drain valve results in slow or even no drainage of water from the washbasin or sink. Furthermore, it is unsatisfactory that the position of the drain valve is not visible when the basin is filled with dishes or murky dirty water.Furthermore, conventional washbasins and sinks have at least two separate openings for the drainage and overflow of water introduced into the basin. These openings typically point in different directions or are widely spaced, usually located in the basin floor and in a side wall or in a side draining area. This results in a complex piping system that takes up a relatively large amount of space beneath the basin.

[0004] Based on this, the invention aims to improve a sanitary basin, in particular a washing or rinsing basin, of the type mentioned above, with regard to its function and appearance by reducing or eliminating one or more of the problems identified above in the prior art.

[0005] This problem is solved by a sanitary basin with the features specified in claim 1. Advantageous embodiments of the solution according to the invention are the subject of the dependent claims referring back to claim 1.

[0006] The sanitary basin according to the invention, in particular a washing or rinsing basin, is characterized in that the drain opening or the drain opening and the overflow are concealed behind at least one cover which is detachably connected to the substantially vertical or steep basin wall.

[0007] This ensures that at least the drain and any dirt adhering to it are not within the direct line of sight of the basin. Furthermore, the solution according to the invention prevents the function of the drain valve from being obstructed by objects placed on the basin floor (e.g., dishes). As will be explained in more detail below, the solution according to the invention allows the respective functional position of the drain valve to be visible even when the basin is filled with dishes or murky wastewater. Preferably, the drain opening and the overflow are concealed together behind at least one cover that is detachably connected to the basin wall. This reduces the complex piping between the drain and overflow outside and, in particular, below the basin, thus gaining usable space for arranging furniture or storage space for items.Preferably, neither the drain opening nor the overflow opening is located in the actual working area of ​​the basin according to the invention. Since the cover is detachably connected to the substantially vertical or steeply sloping basin wall, the basin according to the invention allows for easy cleaning and maintenance of the drain system and the overflow.

[0008] The preferred embodiment of the invention, in which the drain opening and the overflow are concealed together behind at least one cover, particularly simplifies the installation of the drain valve and overflow. For this purpose, the drain valve and the overflow are, for example, arranged or mounted on a common drain housing. In this case, the drain valve and the overflow can be connected to the sanitary basin simultaneously by mounting the common drain housing to the basin. This saves installation time. The basin according to the invention can have a common bottom opening for the drain and the overflow, to which the drain housing can be, or is, mounted. The common drain housing for the drain and the overflow can also be referred to as a central connection or common connection.

[0009] A further embodiment of the invention is characterized in that the basin wall has a niche in which the drain opening, or the drain opening and the overflow, are arranged. This embodiment makes it possible to realize a concealed arrangement, particularly of the drain opening, in a compact design and with minimal additional wall material for covering the drain opening. In particular, this embodiment makes it possible to design the inner surface of the sanitary basin as a substantially closed inner surface.

[0010] According to a further embodiment of the invention, guides for the positive-locking connection of the cover are formed or attached to and / or within the niche. This embodiment enables simple assembly as well as precise and reliable positioning of the cover on the essentially vertical or steeply sloping pool wall.

[0011] According to a further embodiment of the invention, the basin wall containing the niche is the front, rear, right, or left basin wall of the sanitary basin. The variants described here offer several advantages. If the basin wall containing the niche is the front basin wall of the sanitary basin, the cover attached to the niche is barely noticeable, or at least least noticeable, when viewing the basin. Furthermore, this variant is advantageous if, according to a further embodiment of the invention, the cover is movably, preferably slidably, mounted on the basin wall, and the drain valve can be operated by means of the movably mounted cover. In this case, when the sanitary basin is installed, the cover is located very close to the front edge of the basin and is therefore easily accessible and operable for the user.

[0012] The variants where the basin wall containing the niche is the rear, right, or left wall of the sanitary basin allow for a comparatively significant reduction in the amount of wastewater piping that needs to be connected to the basin's drain valve underneath the basin. This optimizes the gain in usable space or storage space for items or furniture beneath the sanitary basin.

[0013] In the four aforementioned niche designs, the drain opening and / or drain housing are preferably elongated, for example oval. This allows the depth of the niche to be kept small for a given size of the drain opening or a given drainage capacity, thus saving space that can be used as installation space or storage space if necessary.

[0014] A further embodiment of the invention provides that the niche in which the drain opening, or the drain opening and the overflow, are arranged is formed in a front or rear corner of the sanitary basin, wherein the cover, viewed horizontally in the installed state, preferably has a concavely curved inner surface. This also allows the depth of the niche to be kept small for a given size of the drain opening or a given drainage capacity, thus saving space that can be used as installation or storage space if necessary. In this embodiment of the niche, the drain opening can preferably be substantially circular. A circular drain opening can be closed particularly reliably and liquid-tight with a suitably designed drain valve.

[0015] As mentioned above, a preferred embodiment of the invention provides that the at least one cover is movably, preferably slidably, mounted on the basin wall. This allows, in particular, convenient access to the drain valve for cleaning and maintenance. For this purpose, the movably mounted cover can, for example, be moved into a maintenance position, preferably pushed upwards, and after maintenance of the drain valve, moved back into a functional or operating position.

[0016] As also mentioned above, a further embodiment of the invention provides that the drain valve can be actuated by means of the movable cover. This extension of the cover's functionality contributes to a simple design and ease of cleaning the sanitary basin.

[0017] A further embodiment of the invention provides that the basin wall has a counter bearing with a locking mechanism supported thereon, wherein the cover has a driver which, when the cover is moved downwards, tensions the locking mechanism, the locking mechanism exercising its locking function in a specific position of the driver. This allows for a reliable and convenient actuation function with respect to the cover.

[0018] A further embodiment of the invention is characterized in that the at least one cover is provided with an actuating mechanism comprising an actuating element and designed such that the drain valve can be actuated by pressing or turning the actuating element. This allows for a reliable and convenient actuating function for the drain valve to be implemented on the cover.

[0019] With regard to simple, reliable and convenient operation of the drain valve, a further embodiment of the invention provides that the drain valve is designed as a spring-loaded valve and / or is equipped with a locking tensioning mechanism.

[0020] A further advantageous embodiment of the invention provides that a drain housing is attached to the drain opening, which is equipped with an overflow. The overflow is designed as an overflow pipe projecting upwards directly from the top of the drain housing. This allows the drain and overflow technology of the sanitary basin according to the invention to be implemented in a particularly space-saving manner. The overflow pipe is preferably connected to the drain housing via a detachable connection, for example, a push-fit or screw connection. This latter embodiment is advantageous from a manufacturing perspective. Furthermore, this embodiment facilitates cleaning of both the overflow and the drain. The upper end of the overflow pipe terminates at a vertical distance from the top of the basin or from the underside of a horizontal rib of the cover.

[0021] In this context, a further embodiment of the invention provides that the drain valve is mounted in the drain housing, preferably in a removable manner. This embodiment allows the drain housing and drain valve to be mounted together. If the drain valve is removable within the drain housing, this facilitates cleaning of the drain housing and any connected wastewater pipe.

[0022] In a further advantageous embodiment, the basin wall and the at least one cover, when mounted on the basin wall, are essentially flush with each other on the inside when viewed horizontally. This allows for a visually seamless sanitary basin, particularly a sink, without any butt joints on the inside of the basin wall.

[0023] A further embodiment of the invention provides that the cover has an optical display and / or at least one electronic control element on its upper surface for controlling at least one valve function. This embodiment advantageously expands the functionality of the cover. For example, the electronic control element or a corresponding control panel on the upper surface of the cover can be used to control (actuate) an electric motor or electromagnetic drain valve. Alternatively or additionally, the electronic control element or the control panel can enable the control (actuation) of an electric motor or electromagnetic water inlet valve. In particular, the control associated with the drain valve can be configured to set different opening states of the drain valve or different drain flow rates.The control system for the water inlet valve can also include temperature control and / or flow control, in particular volume flow control, of the incoming water (drinking water). The control system for the drain valve can be linked to the control system for the water inlet valve, for example, by means of a shared automatic or intelligent control unit. The set water temperature and / or a set water inlet volume and / or a set water inlet flow rate and / or a set opening state of the drain valve or drain flow rate can be displayed visually on the top of the cover.

[0024] Furthermore, the invention allows for individual design adjustments by, for example, making the cover from a different material and / or with a different material color than the sanitary basin.

[0025] The invention is explained in more detail below with reference to a drawing illustrating several exemplary embodiments. The drawing schematically shows: Fig. 1 a sanitary basin according to the invention, inserted into a worktop and with optional water inlet fitting, in a perspective front view; Fig. 2 the sanitary basin according to Fig. 1 without worktop and without water inlet fitting in a perspective rear view, looking at a vertically sliding cover inserted in a niche of the front basin wall; Fig. 3 a section of the sanitary basin according to Fig. 2, showing a vertical section in the area of ​​the concealed drain valve; Fig. 4 a section of the sanitary basin according to Fig. 1 with worktop, showing a vertical section in the area of ​​the concealed overflow; Fig. 5 the sanitary basin according to Fig. 1 in another perspective rear view, similar to the Fig. 2, however, the sliding cover inserted in the niche of the front pool wall is lowered; Fig. 6 the sanitary basin according to Fig. 1 in another perspective rear view, as in Fig. 5, however, the sliding cover is pushed up into a maintenance position; Fig. 7 and Fig. 8 the sanitary basin according to Fig. 1 in another perspective rear view, similar to the Fig. 2 and Fig. 6, however, the sliding cover has been removed; Fig. 9 a detailed representation of the niche formed in the front side wall without cover; Fig. 10 a perspective under-view of the sanitary basin according to Fig. 5 with attached drainage pipe system; Fig. 11 the sanitary basin according to Fig. 2 in a top view; Fig. 12 a detailed view of the top of the cover inserted in the niche; Fig. 13 Another example of a sanitary basin according to the invention, installed in a worktop and with optional water inlet fitting, in a perspective front view; Fig. 14 the sanitary basin according to Fig. 13 without water inlet fitting in top view; Fig. 15 a section of the sanitary basin according to Fig. 13 without worktop, showing a vertical section in the area of ​​the concealed drain valve; Fig. 16 a section of the sanitary basin according to Fig. 13 without worktop, showing a vertical section in the area of ​​the concealed overflow; Fig. 17 the sanitary basin according to Fig. 13 without a worktop and without a water inlet fitting in a perspective rear view, looking at a vertically sliding cover inserted in a corner niche of the basin wall, on which a mechanical control element for operating the drain valve is held; Fig. 18 the sanitary basin according to Fig. 17, wherein the control element is in a lowered position; Fig. 19 the sanitary basin according to Fig. 17 overlooking the corner niche, the cover being moved upwards or removable for maintenance purposes; Fig. 20 the sanitary basin according to Fig. 19 without cover in a top view; and Fig. 21 the sanitary basin according to Fig. 20 in a perspective bottom view.

[0026] The sanitary basin 1 according to the invention, as shown in the drawing, is intended as a sink, particularly for kitchens. However, the basin (sink) 1 can also be used for other purposes, for example in a washroom or laboratory. The basin 1 optionally has a lateral extension 1.1 on its upper side, which serves as a draining surface. The extension (draining surface) 1.1 can be bowl-shaped or basin-shaped and have a slope towards the basin 1 as the main basin.

[0027] The basin 1 is preferably made of plastic, ceramic, or composite material, for example by means of a casting process. It can have a relatively thick wall, e.g., in the range of 6 to 20 mm. Alternatively, such a basin can also be manufactured from comparatively thin sheet steel by means of a forming process, in particular a deep-drawing process.

[0028] Fig. Figure 1 shows a section of a room wall or partition wall 3 on which a worktop 5, for example a kitchen worktop, is mounted. The worktop 5 has a cutout into which a sanitary basin 1 according to the invention is inserted.

[0029] The basin 1 has a laterally projecting, circumferential collar 1.2 on its upper side, which optionally encloses the extension 1.1 serving as a draining surface. The basin 1 rests with the collar 1.2 on the edge of the worktop 5, which surrounds the cutout in the worktop. The collar 1.2 or the extension 1.1 may have a through-opening 1.3 to which an optional water inlet fitting 6 is or can be mounted. The water inlet fitting 6 is preferably equipped with an electronically controlled inlet valve. In particular, the water inlet fitting 6 may have a proximity sensor 6.1 that reacts to approach, i.e., without direct contact.

[0030] The sanitary basin 1 has a basin base 1.4, a basin wall 1.5 which extends substantially vertically or steeply relative to the basin base 1.4, a drain opening 1.9 which is provided with a drain valve 2, and an overflow 4. According to the invention, the drain opening 1.9 and the overflow 4 are concealed behind a cover 8 which is detachably connected to the basin wall 1.5. For this purpose, the basin wall 1.5 has a niche 9 in which the drain opening 1.9 and the overflow 4 are jointly arranged. The cover 8 is, for example, plate-shaped and has an angled plate area or web 8.1 on its upper side. The cover 8 can be made, for example, of plastic material, ceramic material, composite material, or stainless sheet metal. The cover 8 preferably has a completely closed visible surface 8.2 without a through-hole. However, it is also within the scope of the invention that the angled web 81 or plate area a through-opening (not shown) is formed.

[0031] The cover 8 is guided so as to be vertically displaceable, for example by the basin or niche geometry. Preferably, parallel guides 10 are formed or attached in the niche 9 for this purpose, to which the cover 8 is or can be positively connected. The guides 10 can, for example, be implemented in the form of parallel ribs extending vertically or almost vertically along the opposite narrow niche sides 9.1, 9.2. The cover 8 has elements on its vertical or steeply extending edges 8.4, 8.5 that positively engage the guides 10 with minimal play, for example flanges with grooves corresponding to the ribs (guides 10).

[0032] The drain opening 1.9 of the basin 1 according to the invention is formed in a part 1.41 of the basin floor 1.4, this part 1.41 of the basin floor 1.4 extending into the niche 9. In a normal position of the cover 8 inserted into the niche 9, in which the upper surface 8.10 of the cover 8 is substantially flush with the upper surface of the collar 1.2 of the basin 1, the drain opening 1.9 formed in the basin floor 1.4 is not directly visible. Rather, only the completely closed section 1.42 of the basin floor 1.4, located in front of the cover 8, is visible from above.

[0033] The cover 8 and the associated guides 10 arranged in the niche 9 are designed such that, when installed, the basin wall 1.5 and the cover 8 are essentially flush with each other on the inside when viewed horizontally (see figure). Fig. 2 and Fig. 5).

[0034] The drain opening 1.9 is located in the Fig. In the embodiment shown in Figures 1 to 10, the drain opening 1.9 is preferably elongated, for example as an oval hole or a slotted hole. The longitudinal axis of the elongated drain opening 1.9 runs parallel to that of the basin wall 1.5 or the rear wall 9.5 of the niche 9. The drain opening 1.9 also serves as the overflow 4, i.e., the drain opening 1.9 is a common through-opening (penetration) for the drain 11 and the overflow 4.

[0035] A drain housing 12 is arranged on the underside of the basin floor 1.4 in the area of ​​the drain opening 1.9, which surrounds the drain opening 1.9 in a watertight manner. The drain housing 12 defines a common connection for the drain 11 and the overflow 4. The drain housing 12 is elongated, for example, channel-shaped, corresponding to the drain opening 1.9. The overflow 4 is designed as an upwardly projecting overflow pipe directly at the top of the drain housing 12 (see Fig. 4 and Fig. 7) The overflow pipe 4 is connected to the drain housing 12 via a detachable connection, preferably a push-fit or screw connection (see Fig. 8). The upper end of the mounted overflow pipe 4 terminates at a vertical distance from the horizontal rib 8.1 of the cover 8.

[0036] The drain valve 2 is mounted in the drain housing 12 next to the overflow 4. The drain valve 2 is designed as a spring-loaded valve and is equipped with a locking mechanism 13. It has a dirt-catching screen 20 on its upper side. The drain valve 2 can be actuated by means of the vertically sliding cover 8. The locking mechanism (also called a click-clack mechanism) allows two operating positions (functional positions): a (first) operating position in which the drain valve 2 is open and the cover 8 is in the Fig. 2 position shown with the basin floor 1.4 limits an inlet gap 15; and a (second) operating position in which the drain valve 2 is closed and the cover 8 is in the Fig. 5 shown lowered position essentially lies without gaps on the pelvic floor 1.4.

[0037] Furthermore, the basin wall 1.5 has a counter bearing 9.7 in the niche 9, on which the aforementioned locking clamping mechanism 13 or an additional locking clamping mechanism is supported (see Fig. 3 and Fig. 7) In this case, the cover 8 has a driver which, when the cover is moved downwards, tensions the locking clamping mechanism 13 supported on the counter bearing 9.7, whereby the locking clamping mechanism 13 performs its locking function in a specific position of the driver. The driver can be the angled web 8.1 or plate area of ​​the plate-shaped cover 8 (see Figure 7). Fig. 3).

[0038] For cleaning or maintenance purposes, the cover 8 can be pushed or pulled up into a maintenance position and, if necessary, removed (see Fig. 6 to 9). The drain valve 2, including the dirt filter screen 20, can then be removed from the drain housing 12 via the niche 9.

[0039] In the illustrated embodiment, the cover 8 and the niche 9 are positioned or formed on or in the front basin wall 1.5 of the sanitary basin 1. Alternatively, the cover 8 or the niche 9 can also be positioned or formed on or in the rear basin wall 1.6, the right basin wall 1.7, or the left basin wall 1.8 (see Figure 1). Fig. 11) Depending on the arrangement of the cover 8 and / or the niche 9, the sanitary basin 1 according to the invention allows for a significant reduction in the space required for the wastewater pipe 30 to be mounted outside the basin 1 compared to conventional sinks, where the drain is directly visible in the basin floor and the overflow is arranged in a vertical or steeply angled basin wall and / or in the draining area (cf. Fig. 10 and Fig. 11).

[0040] As in the Fig. 11 and Fig. As shown in Figure 12, a further optional embodiment of the invention consists in the cover 8 having an optical display 40, e.g., a light-emitting diode or liquid crystal display, and / or at least one electronic control element 42, e.g., a control panel, on its upper surface for controlling at least one valve function. The electronic control element 42 or control panel can be used to control a water inlet fitting 6 and / or an electrically / electromagnetically actuated drain valve, including setting the temperature of the incoming water and / or setting the volume and / or flow rate of the incoming water. The values ​​of the set parameters can be displayed by the optical display 40.

[0041] In the Fig. Figures 13 to 21 show further embodiments of the invention. As shown there, the invention also includes configurations in which the niche 9' is formed in a front wall corner, for example the left front wall corner 1.50 of the sanitary basin 1' (see Figures 13 to 21). Fig. 14 and Fig. 20). Alternatively, the niche 9' can be formed in the front right wall corner 1.70, the rear left wall corner 1.60, or the rear right wall corner 1.80 of the sanitary basin 1'. The cover 8', when viewed horizontally in its installed state, has a concave curved inner surface 8.2'. The radius of curvature of the inner surface 8.2' of the cover 8' is considerably larger than the radius of curvature of the inner surface of the other wall corners 1.60, 1.70, 1.80 of the basin 1 (see in particular...). Fig. 14 and 17 to 20).

[0042] Furthermore, in the Fig. As can be seen from Figures 13 to 19, the invention also includes embodiments in which the cover 8' is provided with an actuating mechanism comprising an actuating element 85 and designed such that the drain valve 2' can be actuated by pressing or turning the actuating element 85. For this purpose, the actuating element 85 can, for example, be designed as a pressure rod or torsion rod, which is slidably or rotatably mounted on an upper through-opening 82 of the cover 8' and is functionally connected to the drain valve 2' at its lower end. The actuating element 85 is connected to the cover 8', e.g., to its upper horizontal rib 8.1', in such a way that it remains permanently attached to the cover 8' when the cover 8' is moved upwards or removed from the recess 9'. The actuating element 85 can have an actuating head 85 with a diameter wider than that of the rod 85.1.2, while the through-opening 82 of the cover 8' has a stepped inner diameter (cf. . Fig. 15) Below the through-opening 82, the actuating element 85 can be secured against falling out of the through-opening 82 by a locking element (not shown) attached to the rod 85.1, for example a locking ring which engages in a groove (not shown) formed on the rod 85.1.

[0043] The cover 8' is in the Fig. In the embodiment shown in Figures 17 to 19, the guide pins 10' are held in position by guides 10'. The guide pins (guide bolts) 10' are preferably manufactured separately and then connected to the section 1.41' of the basin floor 1.4' located in the niche 9'. For this purpose, holes, preferably bores, e.g., threaded bores, are provided in this section 1.41' of the basin floor 1.4', into which the guide pins 10' are inserted or screwed in a watertight manner. The cover has positive locking elements associated with the guide pins 10', which engage the guide pins 10' when the cover 8' is installed. These positive locking elements of the cover 8' can, for example, be vertical bores in the wall of the cover 8'.

[0044] The cover 8' and the guide pins 10' associated with it, arranged in the niche 9', are designed and arranged such that the basin wall 1.5, 1.7 and the cover 8' are, when viewed horizontally in the assembled state, essentially flush with each other on the inside (see Fig. 14, Fig. 17 and Fig. 18).

[0045] The section 1.41' of the basin floor 1.4' located in the niche 9' has two separate through-holes (openings) 1.91', 1.92', one of which (1.91') is for the drain valve 2' and the other (1.92') for the overflow 4'. The overflow 4' is designed as an overflow pipe projecting upwards directly from the top of the drain housing 12'. The overflow pipe 4' is angled to adapt to the geometry of the niche and the available space. The overflow pipe 4' can be permanently connected to the basin floor 1.4'. The upper end of the overflow pipe 4' terminates at a vertical distance from the horizontal rib 8.1' of the cover 8'. The drain valve 2' located in the niche 9' next to the overflow pipe 4' is equipped with a locking mechanism (so-called click-clack mechanism) which can be operated to close or open the drain valve 2' by means of the actuating element 85.The locking mechanism is integrated into the drain valve 2'. Although the drain valve 2' and the overflow 4' are arranged in separate through-holes 1.91', 1.92', they are associated with a common cup-shaped drain body (drain housing 12') which is connected to the basin 1' at the underside of the basin floor 1.4', covering the through-holes 1.91', 1.92', preferably detachably.

[0046] In the Fig. In the embodiments shown in Figures 13 to 18, the position of the drain valve 2', i.e., its functional state, can be determined from the position of the actuating element 85. If the actuating head 85.2 of the actuating element 85 protrudes above the top of the cover 8', as is the case particularly in the Fig. As shown in Figures 15 to 17, this means that the drain valve 2' is open, or in other words, is in its open position. If, on the other hand, the actuating head 85.2 is essentially flush with the top of the cover 8', as shown in Figures 15 to 17, this means that the drain valve 2' is open, or in other words, in its open position. Fig. As shown in Figure 18, this means that the drain valve 2' is closed, or in other words, is in its closed position.

[0047] The embodiment of the invention is not limited to the exemplary embodiments shown in the drawing. For example, the sanitary basin 1, 1' according to the invention can also have a different shape, for example, as a round sink with a circular or oval basin wall. Furthermore, it is within the scope of the invention to combine detailed solutions from the various exemplary embodiments shown. For example, it is conceivable to combine the features shown in the Fig. 3 and Fig. The mechanism of the cover 8 shown in Figure 7, in which a counter bearing 9.7 is provided on the rear wall 9.5 of the niche 7 for supporting a locking clamping mechanism 13, wherein the locking clamping mechanism 13 rests against the underside of the rear-angled web 8.1 of the cover 8, can also be implemented in embodiments in which the niche is formed in a wall corner of the basin and the cover has a concavely curved inner surface, as shown in the Fig. 14, Fig. 17 and Fig. 18 is shown. Furthermore, it is also conceivable that the ones in the Fig. 15 and Fig. The mechanism of the cover 8' shown in Figure 16, in which the cover 8' has an actuating element 85 and is designed such that the drain valve 2' can be actuated by pressing or turning the actuating element 85, can also be implemented in embodiments in which the niche 9 is formed in a substantially flat or straight basin wall 1.5, 1.6, 1.7 or 1.8 and the cover 8 has a substantially flat inner surface, as shown in the Fig. 2 to 8 are shown.
