Abstract

A flocked antisweating method which applies paste (16) onto part in contact with water inside a low tank of sanitary earthenware (1) or a faucet fitting (20) and fibrous fur (17) is densely set on the paste (16) to form an air layer by said flocking between water and the body, thereby preventing the outer surface thereof from being bedewed.

Description

FIELD OF THE INVENTION

The present invention relates to technique for preventing bedewing on the outer surface of a low tank or a faucet fitting at a sanitary fixture.

PRIOR ART

A low tank storing therein a fixed quantity of water for flushing it into a closet is almost formed of pottery. In winter, a low temperature of water in the low tank enlarges a temperature difference from a room temperature, thereby bedewing the surface of low tank. When such dew grows larger and collects so as to drop as shown in Fig. 4 so that the floor of a toilet room is soused.
When the floor of toilet room is soused, it is often misunderstood that water leaks from a joint at a water supply pipe or through a crack at the low tank, which has frequently occurred in winter.
In order to prevent bedewing on the surface of low tank as the above-mentioned, conventionally it has been proposed to provide a heat insulation layer between the inner surface of low tank and water therein.
In order to provide the conventional heat insulation layer, a foaming agent is applied onto the inner surface of low tank. In detail, paste is uniformly applied thereon and subjected to preheating, thereafter the sol foaming agent is injected into the low tank and then scraped off until the foaming agent is of a predetermined thickness so as to be flattened at the inner surface, the low tank is moved into a heating furnace so as to harden the foaming agent, after the low tank is taken out from the heating furnace, the bores thereof are held therearound to remove burrs, and a surface treatment agent is applied to the low tank to thereby finish it. Accordingly, at the inner surface of low tank is formed a heat insulation layer of predetermined thickness.
For applying the antisweating treatment to the low tank, the foaming agent is stuck onto the inner surface of low tank to form the insulating layer, for which many processes must be carried out, thereby taking much labor and time. Especially, the scrape-off and holding the bores therearound are manual to be inefficient, thereby causing a high manufacturing cost.
Also, the faucet fitting, as the same as the above-mentioned, generates a temperature difference between the faucet fitting and the indoor air so as to be bedewed because cold water passes into the fitting in winter, but there has hitherto been no technique to form the heat insulation layer into the faucet fitting, whereby the bedewing has been misunderstood as water leakage.

SUMMARY OF THE INVENTION

The present invention aims at that sanitary earthenware for storing therein water is applied at its pottery part with paste and fibrous fur is densely set onto the paste in order to simply obtain the heat insulation layer.
The faucet fitting through which water flows is applied on the inner surface with paste, onto which fibrous fur is densely set.
Accordingly, the sanitary earthenware, such as the low tank, or the faucet fitting is easily provided at the inner surface with a heat insulation layer formed of fiber, so that even when a temperature difference is generated between the indoor temperature and the temperature of sanitary earthenware or faucet fitting, the heat insulation layer shuts off heat transmission to the surface, thereby preventing the sanitary earthenware or faucet fitting from being bedewed on the surface thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to Fig. 1, a low tank 1 is formed of pottery, in which a water supply pipe 2 perforates through a water supply bore open at the side wall of the low tank 1, a ball tap 3 in the low tank 1 is connected to the fore end of water supply pipe 2, a float ball 5 is connected to the lower portion of ball tap 3 through an arm 4, and a washhand pipe 7 provided at a lid 8 is connected to the upper portion of ball tap 3 through a flexible hose 6. In the state where the float ball 5 lowers, in other words, the state where no water is in the low tank 1, the ball tap 3 is open to supply water from the water supply pipe 2 into the tank 1 through the fore end of ball tap 3 and washhand pipe 7 and when the float ball 5 rises up to a predetermined position, the ball tap 3 is closed to stop water supply. Reference numeral 10 designates a drain lever. When the drain lever is turned, a float valve 11 is open to discharge from a discharge pipe 12 water in the low tank 1, and 13 designates an overflow pipe.
Thus, a predetermined quantity of water is always stored in the low tank 1. Unless the low tank 1 is not applied with the antisweating treatment, the temperature of water is low and the indoor temperature is high in water, so that the temperature of water is transmitted to the low tank 1, whereby the low tank 1 is bedewed to the position of storing water as shown in Fig. 4.
In order to prevent such bedewing, the present invention has been designed. The low tank 1 is molded from a body, applied with glaze on the surface after dried, and thereafter regularly baked to be a product. Thereafter, the low tank 1 is subjected to the antisweating treatment. In detail, as shown in Fig. 2, paste 16 is uniformly applied onto the inner surface of the low tank 1 and extra fine fur fiber 17 of several mm in length of synthetic resin is densely sprayed onto the paste 16, thereby being flocked. Then, the flocked layer is dried and tightly stuck to the inner surface of low tank 1 not to be peeled off therefrom. Accordingly, even when water is supplied into the low tank 1, the flocked portion forms an air layer not to be submerged by water into the bottom of the layer, thereby forming the heat insulation layer.
When the low tank 1 is flocked, it is possible to spray the fiber 17 by means of voltage using static electricity, whereby flocking means is not defined.
Fig. 3 shows an embodiment in which part of a faucet fitting 20 through which water flows is flocked. As the same as the above-mentioned, paste 16 is applied on part of the inner surface of the body of faucet fitting 20 not in contact with packing 21 or a spindle 22, and fine fiber 17 is sprayed onto the paste 16 and dried to be flocked, whereby the heat insulation layer is formed at the inner surface of faucet fitting 20, in turn the inner surface thereof is prevented from erosion.
In the above-mentioned construction, the low tank storing therein water or the faucet fitting through which water flows is merely flocked at the inner surface thereof to thereby form the heat insulation layer, so that, even when a temperature difference is created between the interior of a room and the inside of the instrument, the surface thereof is not bedewed. Hence, there is no fear that the bedewing is misunderstood as water leakage from a crack or a joint and that water from bedewing flows to stay around the instrument or on the floor.
Also, the flocking treatment is to merely spray fine fiber onto paste, thereby enabling the heat insulation layer forming work to be simply carried out. Hence, energy saving and a low manufacturing cost is expected.
The features disclosed in the foregoing description, in the claims and/or in the accompanying drawings may, both, separately and in any combination thereof, be material for realising the invention in diverse forms thereof.
