Description

Multi-temperature section variable flow water outlet nozzle of instant heating type water dispenser

Technical Field

The utility model relates to the technical field of water dispensers, in particular to a multi-temperature-section variable-flow water outlet nozzle of an instant heating type water dispenser.

Background

The water dispenser is widely applied to places such as families, offices and the like to meet the requirements of people on the quality of drinking water. However, since the early water storage type water dispenser has the defects of boiling water, scaling inside the heating tank, low water outlet temperature and the like, the traditional water dispenser is gradually abandoned by people, and a new heating type water dispenser, namely an instant heating type water dispenser, is produced, and the hot water outlet amount of the instant heating type water dispenser in unit time is much smaller than that of a heat storage type water dispenser. At present, most of the water dispensers, particularly the wall-mounted water dispenser, are designed to be a single water outlet, and the single water outlet is required to flow out of boiling water with a flow rate of about 350 milliliters per minute, normal-temperature water with a flow rate of about 1000 milliliters per minute, and water with different temperatures and different flow rates. This involves the design of the outlet (also called tap) which requires that the outlet opening is not too large, otherwise the flow of hot water is low and a flow break occurs. The water outlet hole is required not to be too small, otherwise, hot water is normally discharged, and the flow of warm water discharged cannot meet the requirement, so that the single-tap water outlet nozzle of the instant heating type water dispenser cannot give consideration to the water discharge of hot water and normal-temperature water.

Therefore, people design an improved structure of a water outlet nozzle of an instant heating type water purifier, for example, the water outlet nozzle disclosed in the document with Chinese patent No. CN206457262U, which comprises a base body, a hollow tube inserted into the base body and a water outlet cap, wherein two blind holes on the side wall of the base body are respectively communicated with a hot water connector and a warm water connector, hot water entering from the hot water connector flows out from a warm water shared water outlet at the bottom of the water outlet cap through a through hole of the hollow tube, a plurality of ribs are arranged on the outer wall of the lower part of the hollow tube at intervals, a warm water flowing groove is enclosed between the adjacent ribs and the outer wall of the hollow tube and the inner wall of the base body, and warm water entering from the warm water connector flows out from the warm water shared water outlet at the bottom of the water outlet cap through the warm water flowing groove. By adopting the water outlet nozzle, hot water and warm water can be discharged from the warm water shared water outlet in an unavailable way, so that the requirement of the water outlet quantity of the hot water and the normal temperature water is met, and the water outlet nozzle is easy to process and assemble.

However, when the warm water is discharged, the warm water only flows through the warm water flow groove, and the flow of the through hole of the hollow pipe is not fully utilized, so that the water discharge amount of the warm water is still required to be further improved under the same volume.
