Description

Water dispenser with cold and hot water separating function

Technical Field

The utility model relates to the technical field of articles for daily use, concretely relates to water dispenser with separation cold and hot water function.

Background

The drinking machine is a device which heats or cools barreled purified water (or mineral water) and is convenient for people to drink; the water dispenser is a domestic product which is produced by solving the problem of drinking water of people, is fashionable and popular with Chinese people due to the improvement of the drinking water quality and the living taste of people, is a domestic product for drinking barreled water of people and is divided into a vertical type and a desk type; in order to meet the drinking habit of Chinese people, the barreled purified water has the functions of a water dispenser and realizes the heating and refrigerating effects, and plays a key role in birth and development of the water dispenser.

The water dispenser is heated, a hot water container is arranged in the water dispenser, a heating rod in the hot water container heats water, and people can achieve the purpose of taking hot water by opening a hot water valve at the bottom of the hot water container. However, most of the time, when the user receives the boiled water, a large amount of cold water is poured into the hot water container, the cold water and the boiled water are mixed to form yin-yang water, and the cold-hot mixed water is drunk before the next heating is finished, but the cold-hot mixed water is not sterilized at high temperature and contains certain bacteria. In addition, after people take hot water, the boiling water in the hot water liner is often remained, and when the water is heated next time, the heating rod can repeatedly heat the boiling water to generate 'thousand boiling water', and the 'thousand boiling water' contains a large amount of heavy metals, so that the 'thousand boiling water' and 'yin-yang water' are very harmful to the health of people after being drunk for a long time.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a water dispenser with cold and hot water separating function, which can avoid the generation of negative and positive water of the water dispenser with cold and hot water separating function.

In order to achieve the above object, the utility model provides a following technical scheme: a water dispenser with a cold and hot water separating function comprises a hot water container, wherein a water inlet is formed in the top of the hot water container, a partition board for dividing the hot water container into an upper cavity and a lower cavity is arranged in the hot water container, the upper cavity and the lower cavity are respectively a heating cavity and a boiling water storage cavity, and a water outlet is formed in the partition board; a switching rod is arranged between the water inlet and the water outlet, a first sealing plug used for sealing the water inlet is arranged at one end of the switching rod, a second sealing plug used for sealing the water outlet is arranged at the other end of the switching rod, a piston mechanism is arranged in the heating cavity and comprises a sliding cavity and a piston rod arranged in the sliding cavity, the piston rod is fixedly connected with the switching rod, expansion liquid is filled in the sealing part of the piston and the sliding cavity, and a first spring is further connected between the piston and the sliding cavity.

The utility model discloses a theory of operation: the first sealing plug does not seal the water inlet, the second sealing plug seals the water outlet, and cold water enters the heating cavity through the water inlet until the heating cavity is filled with water. Heating rod in the hot water courage heats cold water, cold water warms up gradually, and give the slip chamber through heat transfer transmission heat, the inflation liquid in the slip chamber takes place the inflation after being heated, promote the switching rod through the piston rod and move up, first spring is stretched simultaneously, first sealing plug inserts in the water inlet, and the second sealing plug breaks away from the delivery port, the boiling water in the heating chamber enters into the boiling water storage intracavity through the delivery port, the heating rod stops the heating, and because the jam of first sealing plug, cold water does not enter into the boiling water storage intracavity through water inlet and delivery port, so just realized separating cold water and boiling water, cold water can not enter into in the boiling water, can not produce "negative and positive water".

After the heating rod stops heating, the expansion liquid is cooled and contracted, the stretched first spring returns to enable the switching rod, the second sealing plug seals the water outlet, the first sealing plug is separated from the water inlet, and cold water enters the heating cavity through the water inlet.

The utility model has the advantages that: 1. the expansion liquid expands when heated to drive the switching rod to move upwards, the first sealing plug seals the water inlet, the second sealing plug is separated from the water outlet, hot water in the heating cavity is stored in the boiling water storage cavity through the water outlet, cold water cannot enter the boiling water storage cavity through the water outlet, the cold water and the boiling water are separated, and negative and positive water cannot be produced. 2. The boiling water is stored in the boiling water storage cavity through the water outlet without secondary heating, so that the generation of 'thousand boiling water' is prevented.

Furthermore, the bottom of the boiling water storage cavity is communicated with a drain pipe, the drain pipe is communicated with a transverse connecting cavity, the connecting cavity is horizontally and slidably connected with a valve core used for sealing the drain pipe, a second spring is connected between one side of the valve core and the inner wall of the connecting cavity, the connecting cavity is filled with the expansion liquid, and a heating wire is arranged in the connecting cavity. When the heating rod is opened, the heating wire is opened at the same time, the heating wire heats the expansion liquid in the connecting cavity, and the expansion liquid is heated and expanded to push the valve core to move transversely so as to seal the drain pipe. Boiling water enters into the boiling water storage cavity through the water outlet, when hot water is not needed, the heating rod and the heating wire stop heating, the temperature of boiling water and expansion liquid is gradually reduced, the valve core returns to the initial position, the water in the boiling water storage cavity is discharged through the drain pipe, so that the next use can be guaranteed, the boiling water is taken out instead of mixed water, and meanwhile, the water can be prevented from being reserved in the boiling water storage cavity for a long time to cause the breeding of bacteria.

Further, the first sealing plug is in a cone shape, and the second sealing plug is in an inverted cone shape. Such an arrangement enhances the seal because of the special nature of the shape.

Further, the expansion liquid is kerosene or diethyl ether. The swelling performance of kerosene or ether is good.
