  The wash counter made by molding artificial marble plate has the advantages that the surface is clean and has excellent impact resistance, and that it is a solid material that does not stain easily, is easy to clean and is hygienic. It is preferable if the hand-washing counter 101 provided with a washing tub as shown in FIG. 9 can be formed of an artificial marble plate material.

  However, when an artificial marble board is formed by pressing the washing tank and the counter top board together, the counter molded with a single mold has a dedicated size. There is a problem that it is necessary to manufacture a dedicated mold for each size, such as a counter for four persons, and there is a problem that the molding cost is high. Counters molded at each size cannot be diverted to other sizes, and molds of each size must be prepared to meet the needs of various sizes. In addition, the heating press is a four-sided bending process, and if the bending radius at the corner is too small, molding distortion and discoloration will occur in the artificial marble plate material. Therefore, the bending radius at the corner must be increased. There is also a problem that the shape is limited.

  In addition, when the entire surface of the counter equipped with a washing tub is formed by bonding with a cut plate of artificial marble plate material, that is, the front and rear portions are bonded to the front and rear of the horizontally long bottom of the washing tub, and both side portions are bonded to the left and right, When the upper end of each surface part is bonded to the counter top plate and molded, the adhesive surface between the front part and the rear part is exposed on both sides of the long side (left and right direction) of the bottom part of the washing tank where water always flows. There is a risk that the adhesive may deteriorate over time and the strength may be attenuated or water leakage may occur. The adhesive surface that is constantly immersed in water is likely to cause mold and bacteria, and is easily soiled and unsanitary. In addition, the back side of the counter needs to be reinforced in order to compensate for the lack of strength when bonding with a cutting plate. Thus, there is a problem that the molding cost is high.

  In view of such problems of the prior art, the present invention is an artificial marble that is difficult to cause a decrease in strength due to aging deterioration of the adhesive and can be flexibly adapted to change in size, and is hygienic and beautiful in appearance. It is an object to obtain a counter and a hand-washing sink equipped with a washing tank made of metal.

In order to solve the above-mentioned problems, the present invention includes a step of pressing an artificial marble plate having a rectangular shape in plan view to form a long concave body having a substantially U-shaped short cross section, and both ends of the long concave body. A step of closing a part with a lid and bonding and fixing to form a washing tub; a step of bonding and fixing the upper edge of the washing tub to the rim of the opening provided on the countertop made of artificial marble; and The counter marble top plate and the left and right side edges of the countertop are made of artificial marble by a counter manufacturing method comprising the steps of adhering and fixing an artificial marble counter front plate and upper ends of the left and right side plates. It is characterized by manufacturing a hand-washing counter.
Further, the hand-washing counter of the present invention has lids on both ends of a long concave body having a substantially U-shaped cross section continuous in the longitudinal direction at the periphery of the opening provided on the counter top plate made of artificial marble. The upper peripheral edge of the artificial marble washing tub is closed and bonded and fixed, and the upper ends of the counter top plate and the left and right side plates made of artificial marble are attached to the front end and the left and right ends of the counter top plate. It has the structure fixed by adhesion.

According to this, an artificial marble plate material having a rectangular shape in a plan view is pressed, and only two surfaces in the long side direction of the plate material are bent to form a long concave body, and both ends of the long concave body are formed. The lid is bonded and fixed to form a washing tank, and the adhesive surface in this washing tank is only a part of both ends where the flow of water is the least, so it is difficult for the adhesive to deteriorate due to water immersion, It is difficult to get dirty, and it is possible to construct a sanitary hand-washing counter that maintains the original strength.
Further, since the hand washing counter can be manufactured by bending only two surfaces of the artificial marble plate material, the washing tank can be formed with a bending radius smaller than that of the four-surface bending molding. It is possible to form various sizes and shapes under molding conditions with an increased degree of freedom, such as forming a narrow and deep shape.
Furthermore, the long concave body constituting the washing tub can be adjusted in length between both end portions by cutting the end portion to an appropriate length, and is formed into a long concave body for a large number of people. It is possible to form a washing tank for a small number of people with a smaller size than that formed with this press die, and it is possible to manufacture hand wash counters that can be flexibly adapted to various sizes is there.

In the hand-washing counter having the above-described structure, a flat portion having a width sufficient for a bucket to be placed on the bottom of the washing tub is provided, and a water gradient is provided from the left and right ends of the bottom toward the drain outlet formed in the center of the bottom. It is preferable to have the structure formed.
If a water gradient is applied toward the drain outlet at the center of the bottom of the washing tub, it will be difficult for water to soak into the bonded parts of the lids at both ends of the washing tub, and deterioration of the adhesive will be suppressed. If there is a flat part with enough width to place a bucket on the bottom of the bowl, you can improve the convenience of washing things by placing a bucket, washbasin, etc. in the washing tank. It is also suitable for educating children through water work at hand-washing counters.
In the hand-washing counter having the above-described configuration, it is preferable that the width W of the washing tub is set to about 300 mm. Further, the depth D of the washing tank is preferably set to about 150 mm.

As a leg that constitutes a hand-washing sink by supporting a counter having the above-described configuration, in which a washing tank made of a long concave body is bonded and fixed in an opening of a rectangular top plate in plan view, an upper surface of a steel material having an appropriate length is used. A side frame formed by assembling a steel material in an upward U-shape is connected to both ends of a rear frame that is provided with a plurality of reinforcing members standing upright, and a front support rod is connected to the upper ends of both side frames and the reinforcing member. It is preferable to use a structure in which a plurality of beam rods are connected between the upper surfaces of the rear support rods and an upper frame that supports the lower portion of the counter is integrally connected.
According to this, the upper frame formed by laying a plurality of beam rods between the upper surfaces of the front and rear support rods of the leg can contact the entire lower portion of the counter and stably support the counter. In addition, since the front lower part of the counter is a space portion with the counter supported by the leg, the leg does not get in the way of the user's toes. In addition, when a hand sink is provided at a height that can be used by wheelchair users using this leg, the wheelchair is entered into the space secured at the bottom of the counter, so that the user can wash the hand while riding on the wheelchair. It becomes possible to do.
The steel material, the reinforcing material, each support rod, and the beam rod are made of stainless steel or corrosion-resistant iron, etc., with a suitable thickness such as a square tube, a round tube, a flat plate material, and an angle material. The metal material can be used.

In addition, when a hand-washing sink is configured by supporting the counter with the above-described structure with legs, the upper surface is provided on each beam of the upper frame of the leg so that the upper surface is joined to the lower surface of the counter top plate and the washing tub. It is preferable that a reinforcing beam member is attached, and the counter is supported on the upper frame of the leg by placing the lower part of the counter on the reinforcing beam member .
According to this, the load capacity in the vertical direction of the counter is increased by joining and reinforcing a plurality of reinforcing beam members on the lower surfaces of the counter top plate and the washing tank, and the reinforcing beam members are further disposed inside the front plate of the counter. The strength of the counter is increased by joining and supporting the ends, and even if an object is placed in the washing tub or a user leans on the counter, the initial support on the legs is not deformed. It can be stably fixed in position.

In the hand-washing counter having the above structure, the artificial marble as the molding material is preferably a plate-like material made of methacrylic resin containing an inorganic filler, but is not limited thereto. In addition, the molding of the long concave body constituting the washing tank is performed by a known processing method such as heating and softening an artificial marble plate material having an appropriate thickness to an appropriate temperature and press-molding this with a male and female mold. Can be used.
Many hand-washing sinks with long washing tanks at the counter are installed in educational facilities such as kindergartens, nursery schools, and elementary schools. Therefore, it is preferable that the width W of the washing tub is set to about 300 mm and the depth D is set to about 150 mm, as shown in FIG. In addition, according to the 2007 National Health and Nutrition Survey Report by the Ministry of Health, Labor and Welfare, the height of the counter is set to an average height of about 109.6 cm for a 5-year-old child, and the height H to the top of the counter is set to about 540 mm. If it exists, it will become the height which a child etc. are most easy to wash hands, and is preferable. In addition, when hand washing places are set up separately for the senior group and the younger group, the counter for the senior group's hand-washing sink is set at the above-mentioned height, and the average height of a 3-year-old child reported for the younger group is as follows. Since it is about 95 cm, it is preferable to set the height H to the upper end of the counter at about 470 mm. Further, when a hand-washing sink for elementary school children is configured, it is preferable to set the height H to the upper end of the counter to about 600 mm.
The flat portion provided at the bottom of the washing tank is preferably set to a width of about 120 mm to 150 mm where a bucket or a wash basin can be placed. When forming the washing tank with the width W and depth D of the washing tank as the above dimensions, if the bending radius R between the bottom of the washing tank and the front and rear walls is set to about 50 mm, the cross section of the washing tank has a flat bottom. It becomes a bowl-shaped shape where the front and rear wall surfaces are gently curved at both ends, and a flat portion having a width of about 120 mm can be secured at the bottom of the washing tank.
