Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a deodorizing water-sealing pan for a simple flush toilet that is connected to a toilet tank and cleans the inner surface of the toilet bowl with a small amount of water.

(Prior Art) Utility Model Publication No. 56-9749, which was previously proposed by the applicant, shows a mounting structure for a water seal tray. According to this idea, a water-sealing plate, which is previously installed in a funnel-shaped outer tank, is attached to the bottom of the outlet of the toilet body made of ceramic or synthetic resin to block odors.

(Figs. 1 and 2) - (Problems to be solved by the invention) In the conventional water seal mechanism, when the toilet body is made of ceramic, the glaze on the surface of the toilet bowl inevitably drips onto the lower rim of the outlet. It was difficult to get the correct dimensions for the bottom, so I had to carefully fit each piece together to install the water seal pan.

The second point is that when attaching the bearing part that swingably supports the water sealing dish to the outer tank of the water sealing dish, the bearing part that is integrally formed with the outer tank as shown in Fig. The easiest method is to use the flexibility of the synthetic resin material to open the outer tank and fit the shaft, but in order to fit the shaft end without destroying the outer tank, the shaft must be inserted shallowly, causing the wheel to fall off. There was a risk of this, and it was also difficult to place a grease reservoir on the bearing.

As an improved method, there is also a method in which a bearing part as shown in FIG. 3 is inserted as a separately molded product 8' from the upper part of the outer tank.

According to this method, the shaft can be supported without any difficult work, and the grease reservoir can be easily installed, but the number of man-hours required for fixing screws to the outer tank increases.

(Means for Solving the Problems) The measures taken by the present invention to solve the above-mentioned problems are as shown in FIG. The mouth edge was sealed with a water sealing plate, but in the present invention, instead of the conventional outer tank lid 11, the part of the lid that corresponds to the toilet outlet is formed into a cylindrical receiver wider than the diameter of the outlet. At the same time, the drain outlet of the ceramic toilet bowl is formed to a length that makes contact with the upper surface of the outer tank lid, and the water seal opening edge of the water seal tray is formed not at the opening edge of the ceramic toilet bowl but at the opening edge of the receiver.

In addition, without embedding the bearing product 8' in the outer tank body, a recess for receiving the lower surface of the shaft is formed in the outer tank so as to reach the upper edge of the outer tank, and a protrusion that engages with this recess is provided on the lid body. Fix the shaft at the same time as fitting. The lid is fitted into the lid by engaging convex portions provided at several locations on the side of the lid body and recesses provided at matching locations on the outer tank body.

(Function) To explain the assembly procedure, first, drop the shaft of the water seal tray from above into the bearing recess of the outer tank, fit it into the lower part of the bearing, cover the lid with the molded receiver from above, and pop the top surface. Just by opening it, an outer tank with a water seal function is completed. At this time, the shaft retainer that protrudes from the lid also serves as a guide for attaching the lid, and the correct position can be determined by simply aligning the y. Important parts such as the position of the water sealing plate shaft and the length of the receiver are molded from synthetic resin using precisely made molds in advance, so there are no dimensional deviations, and the assembled water sealing plate and outer tank It has a complete water seal function. Next, when attaching this outer tank to the ceramic toilet body, there is no need to fit the water seal tray to the ceramic outlet, which is inaccurate as in the conventional case. small,
Since the only requirement is that the outlet has a good shape as long as it hangs down from the lid surface, the outer tank can be fixed to the toilet bowl with simple work without any problems with the glaze or slight deformation during molding.

(Example) FIG. 1 shows a conventional water seal tray mounting structure.

The toilet bowl outlet hangs down inside the outer tank 7, and its opening touches the top surface of a water-sealing tray that is swingably supported by the outer tank 7, and the outlet is water-sealed with a small amount of water. It is odor resistant.

The conventional outer tank lid 11 merely functions to block odor. Fig. 4 shows a water seal mechanism according to the present invention, in which the water seal tray is swingably attached to the outer tank, but the lid body 21 is not a flat plate, but is integrated with the lid body in order to absorb toilet drainage loss. A cylindrical receiving tube 5 is provided. The diameter of the receiver tube 5 is larger than the diameter of the discharge loss, and the discharge port U is desirably dimensioned so that its tip slightly protrudes into the receiver tube 5.

The length of the pottery outlet is made shorter than the conventional one. Waterproof between the top surface of the outer tank lid and the back surface of the toilet bowl body.
Of course, the backing material can be used and fixed for odor prevention.

Both the outer tank and the lid are molded from chemical-resistant synthetic resin such as polyethylene or polypropylene.

The present invention is also characterized by the assembly of this outer tank lid. That is,
Conventionally, in order to pivotally support the water seal tray in a swingable manner, a method was used in which a bearing was provided with a recess on the side of the outer tank and was pivotally supported in this, as shown in Figure 2, but this method was difficult to assemble, and at the same time, Since it is used permanently, it was not possible to provide a grease reservoir. In order to solve this problem, a method was devised in which a separately molded support shaft with a grease reservoir inside was attached as shown in Fig. 3, 8'. Furthermore, it took time to secure the lid 11 with screws.

In order to solve these problems all at once, the present invention provides a concave part in the outer tank body that serves as the bearing lower surface and the grease reservoir 28.The lower end is in the shape of a semicircular bearing type grease reservoir, and the upper part extends to the edge of the outer tank mouth. The outer wall I is extended to form a 4-bar space. On the other hand, the lid body 21 is provided with a convex portion 4 that fits into this groove, and the lower end is made semi-circular to serve as a shaft holder.A concave portion for grease is formed on the back side of the convex portion 4, so that the shaft of the water seal tray can be attached to the lower bearing. The support shaft is completed at the same time as the cover is mounted on the machine.

Furthermore, in order to complete the installation work of the outer tank and the lid body in a short time without using screws, etc., thick parts 32 are formed in several places on the outer tank and grooves are bored parallel to the opening. A small flat plate 31 is suspended from the corresponding portion, and a projection parallel to the opening is provided on the inner surface thereof.

When assembling, simply place the water seal plate support on the bearing, fill the grease reservoir with grease, and insert the support shaft retainer 4 of the lid body into the shaft groove.This will become the assembly guide groove and press the upper and lower bodies. The assembly work is completed.

(Effects) - A water sealing mechanism is installed at the outlet of the toilet bowl body that functions accurately even if there is some deformation or dripping of the glaze.

■ Even unskilled workers can easily assemble the water seal mechanism, greatly reducing work time.
