Energy-saving heat tank

Abstract

The invention provides an energy-saving heat tank. The energy-saving heat tank comprises an outer cylinder, a top plate, a bottom plate, an electrical heating tube and a helix tube; the top end of theouter cylinder is in sealing connection with the top plate, the bottom end of the outer cylinder is in sealing connection with the bottom plate, the energy-saving heat tank further comprises an innercylinder arranged in a cavity of the outer cylinder, an empty area included in that a straight line where the center axis of the inner cylinder locates extends outward to the inner side wall of any cylinder is an inner cavity, an empty area included in the outer cylinder and the outer side wall of an adjacent cylinder is an outer cavity; a water channel is arranged between the upper end of the inner cylinder and the lower surface of the top plate, the lower end of the inner cylinder is in sealing connection with the bottom plate; the electrical heating tube is fixed on the top plate or the bottom plate, a heating part of the electrical heating tube extends into the inner cavity; the helix tube is arranged in the outer cavity or winds on the outer side wall of the cylinder adjacent to theouter cylinder; an upper opening and lower opening of the helix tube both run through the outer cavity; the bottom plate is provided with a water inlet communicated with the inner cavity, and the outer cylinder or the bottom plate is provided with a water outlet communicated with the outer cavity. Compared with the prior art, the scheme has a significant energy-saving effect and low cost.

Description

technical field [0001] The invention relates to the field of drinking water equipment, in particular to an energy-saving hot tank for water dispensers. Background technique [0002] Some commercial water dispensers, especially the water dispensers for teachers and students in primary and middle schools, need to provide boiled water to teachers and students, and because the students have a short break between classes, this requires the water dispenser to provide instant drinkable cold boiled water at the same time. This drinking water equipment that can provide drinking water (such as providing boiled water and cold boiled water or only providing cold boiled water, etc.) to many people at the same time is also called a drinking water platform in the industry. At present, the heating system and pipeline design of most drinking water platforms are as follows: figure 1 As shown, the heating system wherein is provided with heat tank 23 and heat exchanger 24 respectively, and hea...

AI Technical Summary

Problems solved by technology

Although the system can realize the basic function of providing boiled water and cold boiled water at the same time, the system also has defects: first, the heat tank, heat exchanger and connecting pipelines are exposed to the outside, resulting in a large heat dissipation area and low energy efficiency; second, The heat tank and heat exchanger are set separately and the pipelines connecting each other determine the high cost of manufacturing and installation. At the same time, it also determines that the system requires a certain amount of space to install and install, which is relatively large (referring to the three dimensions of length, width, and height) The space requirements limit the scope of use of the system, and the larger space also means that the casing of the device is larger, which in turn leads to higher manufacturing costs of the casing of the machine
