Description

Technical Field

[0001] The present application relates to the field of building system water supply, and in particular to a domestic drinking water tank. Background Art

[0002] According to Article 3.3.19 of the "Building Water Supply and Drainage Design Standard" GB50099-2019: The water storage renewal time in the drinking water pool (tank) should not exceed 48 hours; Article 3.3.20 stipulates: The drinking water pool (tank) should be equipped with a disinfection device.

[0003] The specification stipulates that the storage time of drinking water in the water tank should not be too long. The longer the storage time, the worse the water quality will be as the residual chlorine in the water is consumed. Therefore, it is particularly important to update the water stored in the water tank as soon as possible to reduce the dead water area. However, the technical solutions of the existing technology do not provide a comprehensive solution to the problem of water storage renewal in drinking water tanks. Summary of the invention

[0004] The purpose of this application is to propose a drinking water tank to solve the above technical problems.

[0005] A domestic drinking water tank comprises a tank body, a water inlet assembly and a control assembly;

[0006] One end of the water inlet assembly is passed into the box body to supply water into the box body, and the other end of the water inlet assembly is connected to the municipal pipe network;

[0007] One end of the water inlet assembly is connected to the control assembly, and the control assembly is used to control the water supply in the box;

[0008] One end of the control component is set in the box, which can receive monitoring signals and monitor water quality according to the preset logic. When there is a problem with the water quality, it can alarm and disinfect the water tank;

[0010] A plurality of partitions are arranged inside the box body, and a cavity is formed between any two adjacent partitions.

[0011] The beneficial effects are: the partition allows the water flow in the cavity to advance in a propulsive manner, ensuring that the water that enters the water tank first can be used by the user first, minimizing the storage time of water in the water tank. In addition, when the volume of the tank reaches a certain level, the partition can also play a structural support role for the tank. The water absorption pit can reduce the ineffective volume at the bottom of the water tank, thereby reducing the dead water area at the bottom.

[0012] Preferably, the water inlet assembly comprises a water inlet pipe, a liquid level control valve is arranged on the water inlet pipe, and a control end of the liquid level control valve is connected to the control assembly.

[0013] The beneficial effects are: setting a liquid level control valve to adjust the water inlet level and the water storage capacity of the water tank according to the occupancy rate of the building or community. At the same time, the digital twin technology can be further used in the control component to dynamically adjust the water tank inlet level according to the water flow of the water supply equipment, user water habits, peak water use period, water use curve and other factors, so as to reduce the invalid water storage in the water tank while ensuring the safety of water supply. In the low-peak water use stage, the water tank replenishment level is lowered to reduce the water storage capacity of the water tank. Before the peak water use, the water tank inlet level is raised, and the pre-watering method is adopted to increase the water storage capacity of the water tank to ensure the safety of water supply.

[0014] Preferably, the control assembly includes a water quality monitor, a disinfection device, a controller, and a liquid level monitor;

[0017] Its beneficial effects are: a water quality monitor is connected to the water absorption pit, and the residence time of the stored water is determined by the residual chlorine. When the residual chlorine is lower than the set value, the water tank is disinfected or emptied through disinfection equipment to ensure water supply safety.

[0018] Preferably, a sealed inspection window is provided at the top of the box body.

[0019] The beneficial effect is that the sealed inspection window is generally in a sealed state, and when it is opened, the water tank can be ventilated and the inside of the water tank can be inspected and operated.

[0020] Preferably, a ventilation pipe is provided on the box body, and a first insect-proof net is provided on the ventilation pipe.
