Description

An installation-free reverse osmosis water dispenser system that can automatically empty the clean water tank

technical field

The utility model relates to an installation-free reverse osmosis water dispenser system that can automatically empty a clean water tank. It belongs to the technical field of drinking water treatment equipment.

Background technique

The pure water machine is a kind of water purification equipment that uses multi-stage filter elements for water purification treatment. Its core technology adopts reverse osmosis membrane filtration technology. In addition to effectively removing floating objects in water, heavy metals, bacteria, viruses, etc., it can also Reduce the salinity and small molecular substances in the water body to meet the multiple needs of drinking water in homes or offices. The working principle of the pure water machine is to send water into the purification and filtration device through the booster pump, and the purified water is stored in the clean water tank, and then injected into the heating or cooling system for the user to drink. The existing water purifier combines the functions of water purification and drinking water into one to meet the multiple needs of drinking water in homes or offices, which is a major change in the way of drinking water. However, in public places such as hotels and restaurants, the water in the clean water tank of the water machine has not been drunk in time and is stored for a long time, or the water in the clean water tank of the water machine is heated repeatedly, and drinking again is not conducive to the user's safety. In good health. Moreover, the water machine will produce a certain amount of waste water during the purification process, and general products will choose to directly discharge this part of the waste water, causing a great waste of water resources.

Utility model content

The technical problem to be solved by the utility model is to provide an installation-free reverse osmosis water dispenser system that can automatically empty the clean water tank, which can prevent the water in the clean water tank and pipeline from deteriorating due to long-term power failure without sterilization.

In order to solve the above problems, the technical scheme adopted in the utility model is as follows:

An installation-free reverse osmosis water dispenser system that can automatically empty the clean water tank, including a raw water cup connected in series through pipelines, a two-way hydraulic control check valve, a first TDS probe, a booster pump, a pre-filter element, a RO Membrane, second TDS probe, clean water tank, water supply pump, reversing valve, instant heater, characterized in that:

An intermediate water tank is installed on the first bypass between the outlet of the reversing valve and the two-way hydraulic control check valve, and a waste water tank is installed on the second bypass between the concentrated water outlet of the RO membrane and the two-way hydraulic control check valve. Compare.

As a further improvement, a partition is arranged inside the raw water cup, and a concentrated water tank is formed between the partition and the wall of the raw water cup, the height of the partition is lower than that of the raw water tank, and the bottom of the concentrated water tank and the raw water cup All are connected with two-way one-way valve. The water outlet is blocked when the raw water cup is removed.

Further, the clean water tank is sequentially connected with the gas one-way valve and the ozone generator through a branch.

Compared with the prior art, the utility model has the beneficial effects of:

1. The utility model sets up an intermediate water tank, and when the clean water tank is used by no one for a long time to reach the set condition, all the water in the clean water tank is discharged to the middle water tank, which ensures the sanitation of the clean water tank when no one uses it for a long time Safe, especially suitable for public places such as hotels and hotels.

2. By setting a certain height partition in the raw water cup, when the concentrated water enters the concentrated water tank and reaches this height, it will overflow into the raw water tank, mix with the raw water and then re-enter the purification and filtration system through the booster pump to achieve concentrated water. The reuse of water has the effect of saving water. At the same time, the water in the intermediate water tank will also participate in the water production process, which greatly saves the amount of wastewater discharged.

3. When customers need to add water, they can take down the original water cup and add water by themselves, which eliminates the cumbersome installation steps of the existing reverse osmosis water machine, and ensures the sanitation and safety of the water tank.

detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings and embodiments. The embodiments are not intended to limit the scope of protection of the utility model. Obviously, those of ordinary skill in the art can obtain other embodiments without paying creative work. These all belong to the protection domain of the present utility model.

As shown in Figure 1, an installation-free reverse osmosis water dispenser system that can automatically empty the clean water tank includes a raw water cup 1 connected in series through a pipeline a, a two-way hydraulic control check valve 2, and a first TDS probe 3 , booster pump 4, front filter element 5, RO membrane 6, second TDS probe 7, clean water tank 9, water supply pump 10, reversing valve 11, instant heater 12, the outlet of the reversing valve An intermediate water tank 13) is installed on the first bypass b between the two-way hydraulic control check valve, and the second bypass d is connected between the concentrated water outlet of the RO membrane and the two-way hydraulic control check valve. Wastewater ratio 8 is installed on the second bypass.

A clapboard 1a is arranged in the raw water cup, and a strong water tank is formed between the clapboard and the wall of the raw water cup. The valves are connected, and the water outlet is blocked when the raw water cup is removed. When the concentrated water enters the concentrated water tank through the second bypass d and reaches the height of the clapboard, it will overflow into the raw water tank, mix with the raw water, and then re-enter the purification and filtration system through the booster pump, so as to achieve the reuse of concentrated water and play a role to the water-saving effect.

The clean water tank is connected with the gas one-way valve 15 and the ozone generator 14 in turn through the branch c.

The control method of the installation-free reverse osmosis water dispenser system that can automatically empty the clean water tank is as follows:

When the power-off time of the reversing valve is less than m hours or no one is using the water machine within n hours of power-on time, the reversing valve is in the state of communicating with the instant heater; when the power-off time is greater than or equal to m hours, or power-on When no one is using the water machine for more than n hours, start the automatic emptying procedure, that is, the reversing valve disconnects the connection with the instant heater, the reversing valve connects the pipeline with the intermediate water tank, and at the same time turns on the water supply pump, All the water in the clean water tank is discharged to the intermediate water tank; when the power failure is over or someone uses the water machine again, restart the water production process. As a preferred time value, the value of m is 4, and the value of n is 24.
