Description

[Detailed description of the invention] This invention relates to sanitary water tank equipment such as sinks and washstands.

Conventionally, as shown in FIG.
As a structure for attaching the water tank 3, an under-counter type structure as shown in FIGS. 2 and 3, and an over-counter type structure as shown in FIGS. 4 and 5 are adopted. In FIG. 2, the flange 3a of the water tank 3 is brought into contact with the lower surface of the top plate 1 via a caulking material 4, and the flange 3a is fixed to the top plate 1 with wood screws 5. Figure 3 shows the wood screws 5' attached to the top plate 1.
The flange 3a is pressed and fixed by an annular frame 6 fixed at. Figure 4 shows an annular frame 7 interposed between the inner surface of the aquarium mounting opening 2 of the top plate 1 and the aquarium 3, and the annular frame 7, L-shaped support 8, and screws 9 attached to the top plate 1. It is something.
The water tank 3 is held between an L-shaped support 8 and an upper plate portion of the annular frame 7. In FIG. 5, the flange 3a' of the water tank 3 is placed over the top surface of the top plate 1.

The over-counter types shown in FIGS. 4 and 5 are inferior in terms of water closing, and the under-counter types shown in FIGS. 2 and 3 are preferable. Most conventional sinks are of the type shown in FIGS. 2 and 3.

However, the ones in Figures 2 and 3 use wood screws 5, 5', so the tightening style of the wood screws 5, 5' differs depending on the material of the top plate 1, and the fixing strength is also low. . For example, if the top plate 1 is made of plywood and wood screws 5, 5' are used, a large number of wood screws 5, 5' will be required to obtain the necessary fixing strength, which will increase the number of steps. Furthermore, the reliability of plywood against deterioration over time and pull-out due to long-term loads is low. In addition, when the top plate 1 is made of resin, it is difficult to tap, and an insert nut must be used, which poses the problem that the process is difficult and increases in number.

Another conventional example is one in which a piece of substrate is provided around the inside of the opening of the top plate, this is supported by a plate from the underside of the top plate, and the flange at the upper edge of the water tank is placed on the piece of substrate and covered with an adhesive. There is. According to this, the water can be reliably drained. However, since adhesive, a board piece, and a backing plate are used, there are problems in that the structure is complicated and manufacturing is time-consuming. Furthermore, since the base of the flange, which is most susceptible to impact, is exposed, there is a problem in that this part is easily damaged.

The purpose of this invention is to provide a sanitary aquarium fixture that is reliable in draining water, simple in manufacture and structure, and capable of protecting the base of the aquarium flange.

The sanitary water tank device of this invention has a water tank mounting opening, and is provided with a top plate having a concave groove on the lower surface of the water tank at a position slightly away from the periphery along the periphery of the mounting opening, and around the upper edge of the water tank. A flange is provided, the flange has a substantially Z-shaped cross section with a distal end portion located below the proximal end portion, and the upper surface of the proximal end portion of the flange is in contact with the bottom surface of the groove. The inner surface of the upper edge of the side wall of the water tank is brought closer to the inner surface of the groove, the flange is fitted into the groove, and the flange of the water tank is embedded and fixed with a hard resin molded in the groove. It is.

According to the structure of this invention, a groove is provided on the bottom surface along the periphery of the aquarium installation opening in the top plate, and the flange of the aquarium is fitted into this groove up to the base, and is embedded and fixed with hard resin. , a reliable water closure is obtained, and there is little deterioration in installation strength.
Moreover, the manufacturing process is also simplified. Furthermore, even if the water tank is made of a material that is susceptible to impact, such as enamel, the weakest flange root portion is hidden within the groove, thereby preventing damage.

Furthermore, since the flange has a substantially Z-shaped cross-section and the tip side part is lifted from the bottom of the concave groove of the top plate, both the front and back sides of the tip side part of the flange are buried in hard resin, and the hard resin and the top part are buried in the hard resin. The contact area with the bottom surface of the concave groove of the plate increases, and the fixing of the water tank and the top plate becomes even more reliable. In addition, since the groove into which the aquarium flange is fitted is provided slightly away from the aquarium mounting opening on the top plate, the part between the groove and the inner circumferential surface of the aquarium attachment opening on the top plate covers the upper edge of the aquarium. This has the advantage that the joint between the top end of the aquarium and the top plate is not visible from the position of the user of the aquarium, so dirt is not noticeable. The inner surface of the side wall of the water tank is provided close to the inner surface of the concave groove of the top plate, which allows for easy positioning of the water tank with respect to the top plate, and facilitates manufacturing.

An example in which this idea is applied to a sink is shown in FIG. This sink has water tank installation opening 2 on top plate 1.
An annular groove 10 is formed on the lower surface along the periphery of the
The flange 3a of the water tank 3 is fitted into this groove 10 and fixed with a hard resin 11. The flange 3a has a substantially Z-shaped cross section with the distal end portion 3b located below the proximal end portion 3c, and the upper surface of the proximal end portion 3c of the flange 3a is formed into a groove 10.
The flange 3a is fitted into the groove 10 so that the inner surface of the upper edge of the side wall of the water tank 3 is brought into contact with the bottom surface of the groove 10 and brought closer to the inner surface of the groove 10. For the hard resin 11, epoxy resin, urethane resin, or the like is used. The hard resin 11 is provided over the entire circumference of the groove 10 and is formed to protrude from the lower surface of the top plate 1. Hard resin 11
As shown in FIG. 7, the top plate 1 is placed face down on a surface plate 12, the water tank 3 is placed upside down on top of this, the mold 13 is placed and pressed, and the inside of this mold 13 is placed. This is done by injecting the hard resin 11 into the. Alternatively, as shown in FIG. 8, the hard resin 11 may be molded by providing a weir 14 on the top plate 1 and pouring resin between the weir 14 and the water tank 3.

With this configuration, the following advantages can be obtained. Since the flange 3a of the water tank 3 is covered with a hard resin, and the water tank 3 and the top plate 1 are integrated with the hard resin 11, the water can be closed much better than the conventional example. Moreover, reliable mounting strength can be obtained.
Unlike the conventional method, there is no need to tighten a large number of screws, and the process is simplified. Since the concave groove 10 of the top plate 1 is provided slightly away from the aquarium installation opening 2,
When the aquarium 3 is made of enamel, the outer surface portion 3a' of the base of the flange 3a, which is weakest to external impact force, can be hidden in the groove 10, thereby preventing the aquarium 3 from being damaged. Because water, hot water, oil, detergent, etc. do not come into direct contact with the fixed part of the aquarium 3,
Deterioration in strength of the fixing portion due to the hard resin 11 and adhesion of dirt are reduced. The use of sealants and caulking materials is reduced. The flange 3a has a substantially Z-shaped cross section, and the distal end portion 3b is raised above the bottom surface of the groove 10 of the top plate 1.
Both the front and back sides of the tip side portion 3b of a are buried in the hard resin 11, the contact area between the hard resin 11 and the bottom surface of the groove 10 of the top plate 1 increases, and the fixation of the water tank 3 and the top plate 1 is more secure. becomes. Flange 3a of water tank 3
Since the concave groove 10 into which the
and the inner peripheral surface of the aquarium mounting opening 2 is the aquarium 3.
It covers the upper edge of the aquarium, and the joint between the upper end of the aquarium 3 and the top plate 1 is not visible from the position of a normal aquarium user, so that dirt is not noticeable. The inner surface of the side wall of the water tank 3 is the top plate 1
Although it is provided close to the inner surface of the groove 10, the aquarium 3 can be positioned relative to the top plate 1, and manufacturing is easy.

Incidentally, although the above embodiment has been described with reference to the case where it is applied to a sink, this invention can also be applied to a washbasin.

As described above, the sanitary aquarium device of this invention has a concave groove on the bottom surface along the periphery of the aquarium installation opening in the top plate, and the flange of the aquarium is fitted into this groove up to the base and embedded with hard resin. Since it is fixed, reliable water closure can be obtained, there is little deterioration in mounting strength, and the manufacturing process is also simplified.
Furthermore, even if the water tank is made of a material that is susceptible to impact, such as enamel, the weakest flange root portion is hidden within the groove to prevent damage.

Furthermore, since the flange has a substantially Z-shaped cross-section and the tip side part is lifted from the bottom of the concave groove of the top plate, both the front and back sides of the tip side part of the flange are buried in hard resin, and the hard resin and the top part are buried in the hard resin. The contact area with the bottom surface of the concave groove of the plate increases, and the fixing of the water tank and the top plate becomes even more reliable. In addition, since the groove into which the aquarium flange is fitted is provided slightly away from the aquarium mounting opening on the top plate, the part between the groove and the inner circumferential surface of the aquarium attachment opening on the top plate covers the upper edge of the aquarium. This has the advantage that the joint between the top of the aquarium and the top plate is not visible from the position of the user of the aquarium, making dirt less noticeable. The inner surface of the side wall of the aquarium is provided close to the inner surface of the groove in the top plate, which has the effect of making it possible to position the aquarium with respect to the top plate and making manufacturing easier.
