Purifier water outlet control system

Abstract

The invention discloses a purifier water outlet control system, which contains a raw water tank (1) for storing raw water, a supercharging device (2), a filter core assembly (3), a cold tank (5) and a master control chip. Raw water in the raw water tank is pressurized by the supercharging device (2) to flow into the filter core assembly (3). The system provided by the invention is characterized in that a water inlet of the cold tank (5) communicates with a water outlet of the filter core assembly (3) through a pipeline; a water outlet pipeline (51) of the cold tank (5) is provided with a water pump (7); and the water pump (7) and a cold water switch (8) are connected with each other and are respectively connected to the master control chip. Based on the prior art, a water purifying box iscanceled in the invention. Therefore, users can drink fresh filtered water. In addition, by the adoption of a structure that the water outlet pipeline of the cold tank is provided with a water pump, which is connected with the cold water switch, and the water pump and the cold water switch are respectively connected to the master control chip, when cold water is in need, a branched cold water switch is turned on, the water pump is connected, and water in the cold tank can be completely pumped out by the water pump for drinking, thus avoiding bacterial growth caused by water stored in the coldtank and raising the drinking water quality for users. Furthermore, the structure of the system is simple and easy to realize.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water outlet control system of the water purifier. Background technique [0002] In the existing technology, such as figure 1 As shown, the water purifier is provided with a raw water tank 1 and a clean water tank 11. The water in the raw water tank is pressurized by the pressure device 2, and the clean water produced by filtering the filter element assembly 3 flows into the clean water tank 11 for storage. The water enters the cold tank 5 by gravity, and flows out from the cold water outlet 6 for the user to take after cooling. When the user needs to take hot water, he can add the set water to the hot tank and use it after heating. However, the water purification machine of this structure has the following defects. When cold water needs to be taken, the water in the cold tank is completely pressed out by the gravity of the water in the clean water tank. If there is no water in the clean wa...

Problems solved by technology

However, the water purifier with this structure has the following defects. When cold water needs to be taken, the water in the cold tank is completely pressed out by the gravity of the water in the clean water tank. If there is no water in the clean water tank, the water in the cold tank cannot Take it out from the tap and only drain it from the cold tank drain located at the rear of the unit

If the user cannot release water from the cold water outlet, it is considered that there is no water in the cold tank. When not in use for a certain period of time, the water remaining in the cold tank will breed bacteria and cause secondary pollution, while the water stored in the clean water tank, If it is not used for a long time, bacteria will also breed, which will bring safety hazards to the quality of drinking water for users
