Description

[Name of invention made by ISA according to Rule 37.2] Instant shower  Technical field

The invention relates to an energy-saving low-carbon, health and safety, environmental protection fashion, no descaling, and automatic discharge of air bubbles, and is suitable for power supply of an ordinary residential 2.5mm2 national standard power line, and the water saving effect can reach 30%-40%, and the energy saving effect can be Up to 40%-50% instant shower.

Background technique

At present, there are two types of fast instant electric water heaters on the market, one is pure fast and hot type, the other is hot water storage type, that is, the heat storage type is a traditional water storage type improvement type, To compensate for the short heating time of the storage type electric water heater; the above two types of electric water heaters generally use heating elements as electric heating tubes, and some manufacturers use quartz tubes or ceramic tubes to apply electric heating films as heating elements. Therefore, they have the following disadvantages:

First, the main problems of fast instant electric water heaters, one is that the rated power is 6-8KW, the water output is small, and unstable, can not meet the requirements of people's bathing comfort, environmental protection safety, energy saving; the second is to increase The water flow rate only increases the heating power to 8-10KW, and even requires the user's power line diameter to be no less than 6mm2. It is difficult for ordinary residential quarters to meet this requirement, and the residential power line must be modified. Third, the electric heating tube is used as the heating element. The electric water heater does not see dirt on the surface, but due to the high temperature of the metal surface outside the electric heating tube and frequent use, the scale of the electric water heater is thickened, which not only increases the heating time, but also consumes a large amount of electric energy, and the water heater The amount of water is reduced; there may even be dangers such as bursting. Therefore, the liner needs regular cleaning by professionals, which increases the cost of maintenance and unsafe factors. The fourth is the use of a heating element coated with an electric heating film on a quartz tube or a ceramic tube. The heat of the outer heating film must be transferred to the water through the wall of the quartz tube or the ceramic tube. Therefore, there is a large thermal resistance and also causes electric heating. The outer side is exposed to the air. If it is used in the bathroom for a long time, the heating power will be attenuated, the heating time will be lengthened, the water temperature will be lowered, and the performance will be degraded. At the same time, if the heating film is exposed to the air, some heat will be lost, resulting in increased energy consumption. Big.

Second, the main problem of hot water storage type, that is, the heat storage type electric water heater is produced to compensate for the short heating time of the storage type electric water heater. It is to preheat the cold water by means of water storage. After reaching a certain temperature, the preheated water is then heated by a hot heater to reach the use temperature. The water heater cannot avoid the disadvantages of the heating element of the electric heating tube, and the thermal efficiency is low, and the scale is regularly removed. Maintenance cost; static heating of water storage in electric water heaters, due to water source, water quality, etc., will cause "dead water", which has always been a major problem in the technology of this type of electric water heater. As a result, problems caused by bacterial growth have led to controversy throughout the industry. .

In summary, the current rapid electric hot water has high energy consumption, small water volume, unstable water temperature, regular cleaning of scale, installation of large-diameter power lines, unhealthy hot water and many other defects, and can not bring energy to consumers. Low-carbon, comfortable, safe, stylish and environmentally friendly bathing life affects the marketing of instant electric water heaters.

Summary of the invention
