Problems solved by technology
Let’s take a foot bath with a volume of 6 liters as an example to increase the basic water temperature from 20°C to the operating temperature of 40°C. The theoretical calculation needs to consume about 504KJ of heat energy (Q=C*M*ΔT), which is converted into electric energy. 0.14Kwh, that is, a foot bath with a power of 800 watts needs to be heated for 10.6 minutes to reach the operating temperature, but the actual measurement time is about 21 minutes, that is, the actual thermal efficiency is only 50.5%, and the wasted heat energy is mainly caused by the heat dissipation of the pipeline during the circulation process. Both increased waiting time and wasted energy
[0004] 2. The service life of the products produced according to the working principle of the existing technology is relatively much lower. The main reasons affecting the service life are the failure of the heating device and the failure of the circulating hot water pump
[0005] ①Because of the circulation heating method, the water in the foot bath is repeatedly circulated and heated to maintain the water temperature in the basin. A large number of impurities and floating objects in the water (such as the original substances and impurities in the water that cause scale formation, and dander produced during the foot washing process) , body hair and grease) will be deposited on the blades or diaphragms of the water pump along with the circulating water, resulting in increased workload of the water pump and damage
Deposited on the heat exchange surface of the heating device, resulting in a gradual decrease in heat exchange efficiency until the heating element is damaged
[0006] ②Another reason for the failure of heating elements is scale
Since the heating element directly heats the tap water in the foot bath, the calcium bicarbonate in the tap water will be transformed into calcium carbonate due to heating and will deposit on the heat exchange surface of the heating element to form scale. The heat generated cannot be absorbed by the water in time, and eventually the heating wire is blown and the heating device fails

The invention discloses an instantaneous foot bath achieving a steam indirect heating function. The foot bath comprises a water tank, a quantitative water feed pump, a 3D circularly-heating steam generator and a steam distribution hood. The water tank is connected with a water inlet of the quantitative water feed pump through a pipeline. A water outlet of the quantitative water feed pump is connected with a water inlet of the 3D circularly-heating steam generator through a pipeline. A steam outlet of the 3D circularly-heating steam generator is connected with a steam inlet of the steam distribution hood through a silicon tube. The steam distribution hood is located at the bottom of a foot tub. The instantaneous foot bath achieving the steam indirect heating function can substantially shorten the heat waiting time before use, saves energy, is environmentally friendly, and is long in service life.
Description
technical field [0001] The invention relates to a foot bath physiotherapy device, in particular to an instantaneous steam indirect heating foot bath. Background technique [0002] At present, the existing one-piece foot baths on the market all use electric heating elements (conventional electric heating tubes, PTC electric heating elements, glass tube electric heaters and steel cup electric heaters, etc.) The water in the foot bath is gradually heated to the required water temperature, see attached figure 1 , which works: [0003] 1. The technology of the existing foot bath adopts the method of circulating heating in terms of working principle, and repeatedly heats the water in the foot bath until the water temperature reaches the required value. The heat loss is very obvious during the whole cycle heating process, especially when the water temperature is close to the set value, this phenomenon is more obvious. Let’s take a foot bath with a volume of 6 liters as an exampl...
