Description

[Detailed explanation of the invention] This invention supplies drinking water to an insulated internal water tank,
This relates to a water supply lid for a water cooler, etc., which is cooled by a built-in refrigeration device, and the cooled drinking water can be taken out at any time by operating a lever or the like when necessary.Hereinafter, one embodiment of this invention will be described. explain.

That is, in the figure, 1 is a water storage tank that is inserted into the outer casing 2 through a heat insulating material A and stores drinking water in a cooled state, and 3 is a top lid that closes the upper opening of this water storage tank 2. Water supply port B to which the water supply hose 4 inserted into the water faucet is connected
has been established.

Reference numeral 5 denotes a closing plate for the opening B, which is integrally extended through a thin threaded part 6 provided on the top plate of the upper lid 3, and 7 is a locking portion provided at the tip of the closing plate 5, which connects the upper lid to the upper lid. 3 is provided with a mating locking portion 8 for fitting and fixing this.

Reference numeral 9 denotes an operation knob for facilitating opening and closing of the closing plate 5, and all of these knobs, including the hinge portion 6, are integrally formed with the upper M3.

Previously, when this type of water cooler was not in use during the winter, etc., a separate cap was used to prevent dirt and dust from entering the water inlet where the water supply hose was removed, but these caps were often lost. In many cases, people would forget to install it.

On the other hand, in the case of this invention, since it is constructed as described above, it naturally does not have the above-mentioned inconveniences of the conventional method, and since the closing plate 5 is a molded extension of the top plate part of the upper cover 3, it is cost-effective. It is inexpensive, and the work to close the water supply port B after the water supply hose 4 is removed can be done by simply pushing in the hanging blocking plate 5, so the water supply port can be easily and reliably closed when not in use. .
