[0009]

In the above-described conventional water supply device with a cow heater, drinking water in the water tank is heated by a sheathed heater provided on the lower surface of the bottom plate of the water tank to prevent the water tank from freezing in winter. . However, since the sheathed heater is attached to the bottom surface of the bottom of the water tank, the heat generated by the sheathed heater is also radiated to the space below the water tank, and there is a problem that the efficiency of heating the drinking water in the water tank is low. .

In order to effectively heat drinking water in an aquarium, a sheathed heater may be provided in the drinking water to directly heat the drinking water. However, there is no prior art in which a sheathed heater is provided in the drinking water. The main reason is that when the drinking water in the aquarium becomes empty, there is a fear that the sheathed heater may be damaged by so-called emptying. In order to avoid damage due to emptying, the watt density of the sheathed heater may be reduced, but if the watt density is reduced, the sheathed heater becomes longer. If the sheath heater becomes long, not only is it expensive, but also it becomes difficult to provide it in the water tank.

An object of the present invention is to provide a cattle heater-equipped water supply device that can directly heat drinking water in a water tank without being damaged even if the water tank becomes empty. In addition, in the case of inspection and cleaning of the water tank, it is necessary to suspend the water supply by suspending the float of the ball tap from the upper part of the water tank with a chain. May be damaged. In the present invention, even if the float is suddenly lifted,
It is another object of the present invention to provide means for avoiding breaking of a chain and breakage of a ball tap.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a water tap having an upper surface opening, a ball tap chamber partitioned by two partition plates which does not reach the bottom of the water tank crossing the water tank, A water supply pipe protruding into the room, a ball tap attached to an upper end of the water supply pipe, and an opening / closing lid for covering an upper surface of the ball tap chamber fixedly attached to the water tank;
In a cow waterer including a chain connected to a float connecting rod of the ball tap and a drain pipe provided in a bottom plate of the water tank, an upper surface horizontally mounted on an inner surface of the water tank below an upper limit water level of the water tank in the ball tap chamber. An open tray, a Shih Tzu heater housed in the tray and attached to the inner surface of the water tank, and a thermostat provided on the outer surface of the water tank, wherein the Shise heater and the thermostat are connected to a power source, and a water heater with a cow heater is provided. And

Further, the above-mentioned water dispenser with a cow heater is provided with a tray cover attached to the tray with a gap between the upper surface of the tray and the tray. Further, the chain connected from the upper part of the water tank to the float connecting rod of the ball tap was connected to the float connecting rod via a coil spring.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a tray accommodating a sheathed heater is horizontally fixed to an inner surface of a water tank in a ball tap chamber below an upper limit water level of the water tank, and a seeds heater is provided in a tray constantly drinking water. The lack of drinking water in the aquarium did not immediately cause emptying.

The tray is provided with a tray cover through a gap between the tray upper surface and the tray so that the drinking water heated by the sheath heater in the tray flows from the ball tap chamber into the water tank. The rising drinking water hit the back of the tray cover and flowed in all directions.

Also, in order to prevent damage to the chain and the ball tap even if the chain for lifting the float connecting rod of the ball tap above the water tank is suddenly pulled up, the chain is connected to the float connecting rod via a coil spring. The coil spring alleviates the sudden lifting force and prevents the cutting of the chain and the damage of the ball tap.
