Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, and more specifically, to a 0-stale water 0-pressure waterway system and drinking water equipment. Background Art

[0002] As people's demand for drinking water quality improves, various drinking water equipment has emerged. These drinking water equipment can usually achieve one or more of the following functions: filtering drinking water, heating drinking water and cooling drinking water. The sales volume of drinking water equipment in my country's market has been increasing year by year, and the industry scale has reached hundreds of billions. After many upgrades, drinking water equipment still generally has the following defects: 1. There is a lot of stale water residue in the water channel of the drinking water equipment, and it will have a peculiar smell after being placed for a long time; 2. Because the drinking water equipment needs to provide hot water (boiling water), the hot water water channel will cause water leakage due to excessive pressure. For defect 1, stainless steel or copper water pipes are generally used in the water channel to increase the pressure resistance of the water pipe and reduce the leakage problem. For defect 2, regular after-sales maintenance is generally adopted, and professionals are asked to dismantle the drinking water equipment to pour out the residual stale water. The above solution cannot fundamentally overcome the above defects, and the cost is also high, which requires professionals to implement. For example, the utility model patent with publication number CN111820743A and name of "Water system of water dispenser and water dispenser with the same" discloses a water system for drinking water equipment, which includes a water storage container, a cold water pipe, a hot water pipe, a cold water pump, a hot water pump, a refrigeration device and a heating device, wherein the heating device is connected to the hot water pipe. Due to the high pressure of hot water, it is very easy to cause water leakage in the hot water pipe. The residual water in the waterway and the devices arranged on the waterway cannot be discharged out of the drinking water equipment in time, causing the drinking water equipment to have an odor.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0026] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0027] like Figure 1 As shown, the utility model provides a 0 stale water 0 pressure waterway system, comprising:

[0028] The water tank part includes a hot water tank 1 and a cold water tank 2;

[0029] The pressure relief part includes a pressure relief water tank 3, a water passage and a steam passage are provided between the pressure relief water tank and the hot water tank, and a water passage is provided between the pressure relief water tank and the cold water tank;

[0030] The reflux part includes a reflux component and a water inlet pipeline arranged on the reflux integrated plate 22. The reflux component, the water inlet pipeline, the pressure relief part and the water tank part form a water supply passage and a residual water circulation loop, wherein the pressure relief part is installed at a higher height than the reflux part.

[0031] In the above technical scheme, the 0 stale water 0 pressure water system is a water system with a long life and low maintenance rate, which includes a water tank part, a pressure relief part and a reflux part forming a water circuit loop, the water tank part includes a hot water tank 1 and a cold water tank 2, which are used to heat or cool drinking water; the pressure relief part includes a pressure relief water tank 3, the pressure relief water tank 3 and the upper and middle parts of the hot water tank 1 are connected through a steam pressure relief pipe 4 to form a steam passage, the high-temperature water vapor in the hot water tank 1 is passed into the pressure relief water tank 3 through the steam pressure relief pipe 4 to relieve the pressure of the high-temperature hot water tank 1, the pressure relief water tank is provided with a pressure relief water tank outlet, the pressure relief water tank outlet is connected to the hot water tank inlet pipe 20 and the cold water tank inlet pipe 21 through the fourth joint 18, the hot water tank inlet pipe 20 and the cold water tank inlet pipe 21 are respectively connected to the hot water tank 1 and the cold water tank 2 and form a water circuit respectively, so as to add drinking water into the hot water tank 1 and the cold water tank 2; the reflux part includes an inlet pipe and a reflux component, which is used to transfer water The residual water in the circuit returns to the pressure relief water tank 3 for continued use, and at the same time, water is taken from the water source into the pressure relief water tank 3 through the water inlet pipe. If the water source is a water source after filtering of tap water, it has a certain water pressure. The water inlet pipe transports the water source with a certain water pressure to the pressure relief water tank through the reflux component, which is equivalent to directly connecting the tap water after filtration to the pressure relief water tank 3.
