Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to kitchen furniture, such as a sink top plate, which uses resin concrete, which is a synthetic resin for casting and a filler added thereto, as a material.

Recently, with the spread of system kitchens, post-home tops made of plywood and rolled melanin decorative boards have been used as materials for sink tops. However, since this top plate has a wooden cut end for the top plate hole for attaching the aquarium, it is common practice to inject urethane resin into this part to connect it to the aquarium part and waterproof the cut end. However, with this method, resin injection is costly, and in terms of performance, the melamine decorative board may separate from the plywood, or the melamine decorative board may crack, making it prone to complaints. In order to solve this problem, as shown in FIGS. 5 and 6, a method has been adopted in which resin concrete is used as the top plate material and the top plate is formed by injection molding. Figure 5 shows a structure in which a water tank flange 20 is placed on the top plate top surface 21 on a top plate 19 in which holes 18 have been drilled in advance, and a sixth
The figure shows holes 23 made in advance on the top plate 22, then a water tank section attached to the bottom surface 24, metal fittings 25 and bolts 2
6 and 6 are fixed together using a nut 27 formed at the same time as the molding process. However, these methods also
For example, in FIG. 5, the water tank flange is higher than the top surface of the top plate, and the water accumulated on the top plate cannot flow into the tank, resulting in a drawback in terms of drainage. On the other hand, Figure 6 shows a method of fixing to the bottom of the top plate using water tank metal fittings, but this also requires a nut to be molded into the resin concrete at the same time for fixing, which requires a lot of man-hours and also requires metal fittings and bolts. There were technical and economical difficulties.

The present invention solves the above-mentioned problems and provides kitchen furniture including a top plate, etc., which is made of strong material, has a simple structure, is clean, and can be constructed at low cost. The configuration will be explained below with reference to the drawings.

In Figures 1 to 4, 1 is a resin concrete top plate made of polyester resin with addition of kansui stone powder as a filler, and a sink cabinet consisting of a back plate 2, side plates 3, a storage box 4, and a door 5 on the front. It is installed. Reference numeral 6 denotes a water tank whose upper end is simultaneously insert-molded and integrally fixed to resin concrete, and a water splash prevention protrusion 7 is formed on the upper end of the water tank 6. Further, several holes 10 are formed in the flange portion 8 and the upper side wall 9 of the water tank 6, so that resin concrete can penetrate into these holes during integral molding and be fixed together.

In forming this top plate, as shown in FIG. 4, a hollow hole 12 made of an elastic material such as rubber and used for positioning the water tank is set in the lower mold 11 with a guide pin 13, and a hole 12 is set in the lower mold 11 at the center of the lower mold. Water tank 6 positioning jig 14
A water tank 6 is placed on the top. After the water tank 6 is set, the upper mold 15 is placed on it. The upper mold 15 has a resin injection port 16
An air vent port 17 is formed. On the other hand, the middle hole 1
2 is formed in a concave shape at the upper end of the water tank 6, so that a water splash prevention protrusion 7 is formed after molding the resin concrete. The holes 10 in the flange part 8 of the water tank 6 have an anchor effect that allows the resin concrete top plate 1 and the water tank 6 to be firmly fixed during molding, and the holes in the vertical part of the water tank have the anchor effect as well as the anchor effect on the top plate. This has the effect of increasing the strength of the protrusion formed in the opening against impacts.

Also, the water tank is attached from the back side of the opening in the top plate, which is designed to have higher strength than when the flange of the water tank is exposed at the top. If the flange is exposed, objects may come into contact with it while working in the kitchen, creating a gap between the flange and the top plate, which can lead to water leakage, and in the case of an enamel aquarium, if objects come into contact with the flange corners. However, in the present invention, there were risks such as the enamel layer easily flying off.
These dangers have disappeared.

Furthermore, the ridges at the opening of the top plate prevent water from splashing during washing operations, and by positioning the water tank flange on an extension of the ridges, static loads and impact loads are applied to the water tank. The thickness of the top plate, which receives the most force through the flange of the aquarium, is increased to increase its strength. Further, a stepped portion was formed around the entire circumference of the upper end of the opening of the top plate to serve as a sliding portion for the draining plate.

Resin concrete was selected as the material for the top plate because it is made up of 70% stone powder, so the price is stable and inexpensive, it can be colored freely, has design advantages, can be molded, and can be used for aquariums. This is because it can be fixed at the same time and is easy to process, which is also advantageous in terms of man-hours. In terms of performance, it is free from the cracks and blisters that occur with conventional melamine decorative boards, and even if scratches do occur, they can be regenerated by polishing.

As described above, the present invention is capable of integrally molding a horizontal top plate using resin concrete, and at the same time, it is possible to securely fix the water tank to the opening, and there is no need to drill holes after molding, resulting in cleanliness. As a result, it has become possible to provide kitchen furniture such as a top plate that is functionally superior in terms of water drainage and water splash prevention and is also inexpensive. The upper end and flange of the water tank 6 are machined with holes 10, which strengthens the adhesion between the resin concrete and the water tank, increases the strength of the ridges 7 on the periphery, and The horizontal surface of the flange of the water tank is located within the top plate, making it solid.
