Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a water outlet device and drinking water equipment. Background Art

[0002] Traditional water dispensers are equipped with a normal temperature water tank inside. Drinking water can directly enter the normal temperature water tank of the water dispenser, and then enter the hot water tank or flow out directly from the normal temperature water outlet. In this process, the normal temperature water tank must be connected to the outside air for exchange, which causes the normal temperature water tank to be polluted by the outside air for the second time, resulting in excessive bacteria, algae growth, etc.

[0003] To this end, the Chinese patent application number CN201821064956.8 "A drinking fountain capable of preventing secondary pollution" discloses a drinking fountain capable of preventing secondary pollution, comprising a main water inlet pipe, a normal temperature water pipe connected to the main water inlet pipe, a hot water pipe connected to the main water inlet pipe, and a main water outlet pipe connected to both the normal temperature water pipe and the hot water pipe, the normal temperature water pipe comprising a normal temperature water inlet pipe and a normal temperature water outlet pipe, the hot water pipe comprising a hot water inlet pipe, a hot water outlet pipe, and a hot water tank for heating water arranged between the hot water inlet pipe and the hot water outlet pipe, the hot water outlet pipe, the normal temperature water outlet pipe and the main water outlet pipe are interconnected by a three-way pipe fitting; the normal temperature water inlet pipe, the hot water inlet pipe and the main water inlet pipe are interconnected by a three-way pipe fitting. The pipeline design has been changed to achieve full pipeline closure; drinking water is directly supplied through pipeline pressure, abandoning the previous design of a normal temperature water tank; hot water can be directly supplied from the drinking water source directly into the hot water tank through pipeline pressure, then heated and flowed out, avoiding excessive contact between drinking water and air, making drinking water cleaner and more reliable.

[0004] However, in the above scheme, firstly, when the normal temperature water outlet pipe takes water for the first time, the water pressure is relatively high, which may splash water onto the user; secondly, water accumulated in the normal temperature water outlet pipe and the hot water outlet pipe may easily cause dripping from the water outlet. Generally, additional drain solenoid valves are required at the normal temperature water outlet pipe and the hot water outlet pipe, which results in a complicated structure. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a water outlet device with a simple structure, which can avoid splashing or dripping of water from the water outlet, in view of the current status of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a drinking water device using the above-mentioned water outlet device.

[0007] The technical solution adopted by the utility model to solve the first technical problem mentioned above is: a water outlet device, a normal temperature water outlet pipe, a hot water outlet pipe and a main water outlet pipe, characterized in that: the top end port of the main water outlet pipe is a hot water inlet, the bottom end port of the main water outlet pipe is a water outlet, the side of the main water outlet pipe has a normal temperature water inlet, the outlet of the normal temperature water outlet pipe is connected to the normal temperature water inlet of the main water outlet pipe, the outlet of the hot water outlet pipe is connected to the hot water inlet of the main water outlet pipe, a water outlet valve is installed at the outlet of the hot water outlet pipe, and the end section of the normal temperature water outlet pipe is at least partially an inverted U-shaped pipe.

[0008] In order to conveniently control the on-off of the water flow in the normal temperature water outlet pipe, an inlet valve is installed at the water inlet of the normal temperature water outlet pipe.

[0009] In order to sterilize the water flow in the normal temperature water outlet pipe, a sterilizer is installed on the normal temperature water outlet pipe, and the U-shaped pipe is located downstream of the sterilizer.

[0010] Preferably, the sterilizer is a mercury lamp.

[0011] In order to facilitate the discharge of gas in the normal temperature water outlet pipe, a second exhaust pipe is connected to the side wall of the normal temperature water outlet pipe close to its water outlet.

[0012] In order to facilitate water supply, the main water outlet pipe is arranged vertically.

[0013] The technical solution adopted by the utility model to solve the second technical problem is: a drinking water device using the above-mentioned water outlet device.

[0014] In order to facilitate sufficient supply of hot water, a hot water tank is also included. The side of the hot water tank has a water outlet, and the water inlet of the hot water outlet pipe is connected to the water outlet of the hot water tank.

[0015] In order to facilitate water inlet, sewage discharge and exhaust, the bottom of the hot water tank is connected with a water inlet pipe, a sewage pipe and a first exhaust pipe.

[0016] In order to facilitate the stable installation of the hot water tank, a support plate is also included, on which the hot water tank is placed, and on which the water inlet pipe, the sewage pipe and the first exhaust pipe are passed.

[0017] Compared with the prior art, the advantages of the utility model are: by partially setting the end section of the normal temperature water outlet pipe as an inverted U-shaped tube, on the one hand, it can buffer the water pressure to avoid splashing of water at the outlet, and on the other hand, it can prevent water accumulation in the normal temperature water outlet pipe from causing dripping at the outlet, and the structure is simple.
