Problems solved by technology

[0006] 1. Difficult to clean
After the water dispenser is used for a period of time (the length of time is related to the water quality), scale will form on the outer wall of the electric heating tube and the inner wall of the tank, which will affect the water quality
In addition, the scale on the electric heating tube will also reduce the heat transfer efficiency, and the operating temperature of the electric heating tube will increase, which will affect the service life of the electric heating tube
Therefore, it is necessary to clean the hot tank, and the stainless steel tank body is a non-detachable structure and cannot be disassembled for cleaning
The usual method is to pour an acidic solution (such as citric acid) into the hot tank to dissolve the scale on the electric heating tube, but the effect is not ideal
[0007] 2. Cannot be repaired
If the electric heating tube has been used for a long time, or there is no water and dry burning, the electric heating tube will be damaged, and the water dispenser will not work normally.
Since the stainless steel tank cannot be disassembled, the electric heating tube and the stainless steel tank can only be scrapped together during maintenance, and then replaced with a new heating tank, which is a great waste
[0008] 3. The seal is unreliable, and leakage often occurs
[0009] 4. Water quality is difficult to guarantee
[0010] 5. Poor insulation performance and large heat loss
In order to reduce costs, hot tanks usually use low-density foam as the insulation layer, which has a poor insulation effect
The water dispenser is usually heated by the electric heating tube every 20 to 40 minutes. This repeated heating not only wastes electric energy but also deteriorates the water quality.

Abstract

The invention provides a sanitary fluid electric heating pot. A water outlet opening and a water inlet opening are arranged on the pot body of the electric heating pot, an electric heater is arranged in the pot body, the pot body consists of two parts which are connected through a detachable structure, a seal ring is arranged at the connecting position, and the pot body is made from nonmetal material. The invention is mainly used for heating the drinking water on a water dispenser, and also can be used for heating sanitary fluid on the similar products. Compared with the heating pot of the water dispenser in the prior art, the invention has the advantages that the water quality is ensured, the washing is convenient, the maintenance is easy, the seal is reliable, the assembly is simple, the heat preservation performance is good, and the production cost is not high.

Description

technical field [0001] The invention relates to the technical field of sanitary liquid heating, in particular to an electric heating tank for sanitary liquid which can be used in drinking water dispensers to heat drinking water. Background technique [0002] Along with the raising of people's living standard, the use of water dispenser is very popular now. The hot tank in the water dispenser is usually made of stainless steel, and its heating method is designed as an internal heating type or an external heating type. [0003] The externally heated hot tank structure is to install the electric heater on the outer surface of the stainless steel tank body. The biggest defect of this design method is that it emits more heat to the environment, the utilization rate of heat energy is low, and the manufacturing cost is high. , has now been largely eliminated. [0004] The internal heating type heat tank structure is adopted, and the electric heating tube is placed in the stainles...
