JPH069096Y2 - Drain trap for sink with garbage storage basket - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a drain trap for a sink installed in a kitchen.

<Prior Art> Conventional drain traps for sinks (see FIG. 2) have almost the same configuration, so that compatibility of parts has been obtained in the last few years and standardization is progressing. is the current situation. That is, a dust storage basket attached to the bottom of the sink sink can be freely inserted into and removed from the drain storage basket, and the opening of the dust storage basket is radially cut from the center to form a petal-shaped rubber deodorant. An inner lid is fitted, and a water stop lid is detachably attached to the upper side of the inner lid.

<Problems to be solved by the invention> However, in the above-mentioned conventional example, since the deodorant inner lid is made of rubber, it is particularly in the sink of the sink where temperature changes drastically (sometimes hot water is poured in winter). Therefore, it is difficult to keep the closed state because the rubber restoration performance deteriorates due to the significant change over time, and the deodorant effect is reduced, and the closed state is insufficient, so small kitchen utensils and small eating utensils There was a drawback such as dropping them into the garbage storage basket and forgetting to pick them up and throwing them away with the garbage.

Therefore, the present invention aims to solve the drawbacks of the conventional example by improving the deodorant inner lid.

<Means for solving the problem> A deodorant inner lid made of a shape memory synthetic resin that causes a phase transition due to heat of a specific temperature in the mouth of a dust storage basket attached to the bottom of a sink sink can be freely inserted and removed. I will do it.

<Function> By providing the deodorant inner lid made of a shape memory synthetic resin material having a phase transition temperature at a point higher than room temperature, the petaloid tongue of the deodorant lid is pushed open at room temperature to throw in the garbage, at that time. The history phenomenon of the generated deformation is immediately restored to the memorized shape at the time of processing by pouring hot water above the phase transition temperature (critical point).

<Embodiment> Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. As shown in FIGS.
The drainage trap main body 2 is inserted into the bottom mounting opening of the trap main body 2 and is supported by the upper end flange 3 of the trap main body 2, and the tightening nut is screwed to the flange 3 and the outer periphery of the trap main body 2 near the flange portion. 4 and 4 hold the attachment edge 1'of the sink, and the upper end flange portion 6 of the dust storage basket 5 is placed and supported on the horizontal step portion 3'formed near the mouth portion of the trap body 2. Furthermore, a shape memory synthetic resin deodorant inner lid 9 is detachably fitted into the upper end opening of the trap body 2, and a knob 12 is attached in the ring-shaped portion 7 of the inner lid 9.
A water stop lid 10 attached by a screw 13 inserted from 11 is freely attached and detached.

Further, as for the details of the deodorant inner lid 9, an annular groove is formed on the lower surface of the ring-shaped portion 7 to ensure contact between the inside of the upper end opening of the trap body 2 and the outside of the water shut lid 10. I have to.

The valve plate portion 8 surrounded by the ring-shaped portion 7 of the inner lid 9
Has a petal-shaped tongue piece 8'formed by forming radial cuts from the central portion thereof in a conformal manner. Such a shape has a critical temperature at which a phase transition occurs in the case of a shape memory synthetic resin. Point C. It can be molded at P (Critical Point) or higher.

For example, in the trade name of polynorbornene, C.I. The P temperature is about 35 ° C., which is considerably higher than the normal temperature, and if the desired shape is formed above this temperature, the C.P. When heated to a P temperature of 35 ° C or higher, it regains its original shape.

The present invention uses the above shape memory synthetic resin material for normal use with the water-stop lid 10 removed, and each time the kitchen waste is pushed open the tongue piece 8'of the inner lid 9, the garbage storage basket is opened. Discard within 5. In that case, if the inner lid tongue piece 8'is not completely returned to its original shape, an instantaneous water heater or another water heater,
By pouring hot water or hot air of 35 ° C or more from pots, kettles, etc., it easily returns to a thick shape and has deodorant effect.

Then, in order to collect water in the sink, the water blocking lid 10 may be fitted into the inner peripheral portion of the deodorant inner lid 9.

<Effects of the device> Since the inner cover of the present invention is made of the shape memory synthetic resin as described above, it is possible to prevent the deterioration of the shape restoring force due to fatigue, deterioration, aging and the like like those formed by conventional rubber. In addition, by heating, the tongue pieces of the valve plate portion can be surely returned, and the rise of a foul odor is prevented. And it is a highly practical device that has excellent effects such as preventing falling of small tools such as spoons and forks as before.
