Closed type barrel water drinking machine

Abstract

The invention relates to the enclosed type bulk drinking water machine, belonging to the daily water intaking appliance technical field. The upper part of the drinking water machine is provided with an inlet matching with the bucket outlet, also an aptitude head is arranged thereon spliced with the bucket outlet. A water heater having a hot water valve outlet is arranged in the machine body, and the lower rend of the aptitude head is directly communicated with the upper end of the conduit pipe, while the lower end of the conduit pipe is communicated with the basically horizontal cold water pipe. One end of the cold water pipe is equipped with a cold water outlet of the cold water valve, and the other end is communicated with the upper end of the basically vertical hot water inlet pipe by an inverse U-shape pipe, while the lower end of the hot water inlet pipe is connected with the lower part of the heater, and the middle part of the hot water inlet pipe is connected with the top of the heater by the upwards extending hot air connecting tube. Thereby, a self-enclosing system is formed to avoid the secondary pollution, meanwhile to make the hot air to reduce to the water to return to the heater after chilling, and isolate the cold and hot water to contact and ensure the supplying function of the original cold and hot water in the drinking water machine.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a closed barreled water dispenser, which belongs to the technical field of daily drinking water appliances. Background technique [0002] Drinking water dispenser is the drinking water utensil widely used in many occasions such as office and household etc. at present. The structure of earlier water dispenser is identical, and bucket is buckled upside down during use on the plug joint (being called smart head usually) in the water storage basin above water dispenser. The water in the bucket flows back into the water storage basin of the water dispenser through the water outlet through the exchange of water and steam; when the water storage space in the water dispenser is filled and the water level in the water storage basin rises to the mouth of the bucket, it will automatically close and stop Hydrate. When one of the cold and hot valves of the water dispenser released water, the water level...

AI Technical Summary

Problems solved by technology

[0003] 1. The exchange of water and steam causes secondary pollution of the pure water in the bucket;

[0004] 2. The water in the water storage basin is directly connected to the outside world, which will also cause secondary pollution;

[0005] 3. The turnover of buckets will cause secondary pollution

However, due to the high cost of direct drinking machines and the many defects of bagged water, and the need for regular cleaning and replacement of filter membranes, it brings worries and troubles to users and is difficult to promote

The media often reports on the problems caused by the secondary pollution of pure water, but there is no good solution so far

[0007] The applicant for this patent once proposed a patent application whose application number is 2006200687397 and whose name is "Disposable bottled water packaging)", the technical solution in which can solve the two major problems of water barrel secondary pollution and soda-water exchange pollution during use, but not It involves the secondary pollution problem of the smart head of the traditional water dispenser itself and the water storage basin
