Description

Instant heating type heating member subassembly that drinking water equipment was used Technical Field The utility model relates to the technical field of heating for drinking water, in particular to an instant heating type heating body assembly for drinking water equipment. Background The instant heating type heating body assembly is widely applied to household appliance products such as water dispensers, water purifying and drinking machines at present, and needs not to heat water in advance and wait for a long time, and can be taken immediately, thereby bringing great convenience to consumers. The instant heating type heating body such as a straight tube type heating body made of materials such as quartz, silicon nitride and the like is used on the existing household drinking water equipment, and the inner wall of the heating tube is smooth, so that fluid (water) is in a relatively stable laminar flow state when in heating operation, and tiny bubbles are easily generated on the inner surface, thereby reducing heat transfer capacity and heat efficiency. Meanwhile, the generation of bubbles reduces the surface area of the inner tube, so that the power density of the inner tube is increased, and meanwhile, the temperature in the bubbles is higher than the temperature of surrounding water, so that the tube wall occupied by the bubbles is in a dry burning state, and the inner tube works for a long time in the dry burning state, so that the service life of the heating tube is greatly reduced. In order to solve the problems, a solution is proposed by the prior China patent application for a spiral heating device (CN 107007153A) of a quick-heating water dispenser, which is characterized in that a threaded rod is arranged in a heating pipe so that water flows along a gap between the threaded rod and the heating pipe in a spiral manner, so that a longer and more stable water channel is obtained, the heat efficiency can be effectively improved, the generation of bubbles can be reduced in a spiral operation mode, the service life of the heating pipe is prolonged, the manufacturing cost of a heating body component can be increased due to the arrangement of the threaded rod in the heating pipe, the water resistance can be increased due to the arrangement of the threaded rod, the flow is greatly influenced, and the improvement space is provided. Disclosure of utility model The utility model aims to overcome the defects in the prior art, and provides an instant heating body assembly for drinking water equipment, wherein a heating pipe with a bulge part on the inner wall can be conveniently manufactured by sintering through a die, the manufacturing is convenient and the cost is low, meanwhile, the effective contact area between the heating pipe and water flow is effectively increased through the arrangement of the bulge part, so that the heat efficiency is improved, and moreover, the bulge part arranged in a staggered way and the water flow act to form severe turbulence, so that the generation of bubbles is effectively reduced, and the service life of the heating pipe is further prolonged. In order to achieve the above purpose, the utility model provides an instant heating body assembly for drinking water equipment, which comprises a heating pipe, a water inlet end cover, a water outlet end cover and a heating electrode, wherein the heating pipe is of a cylindrical structure, the water inlet end cover and the water outlet end cover are respectively arranged at two ends of an inlet and an outlet of the heating pipe in a sealing fit manner, one end of the heating electrode is sleeved on the heating pipe, the other end of the heating electrode is connected with an external power supply, a plurality of protruding parts are arranged on the inner wall of the heating pipe along the flowing direction, and two adjacent protruding parts in the flowing direction are arranged in a staggered manner.
