Abstract

The invention particularly relates to a temperature control method for a foot bath device. The temperature control device comprises a temperature sensor and a microprocessor which are arranged in a foot tub; the input end of the microprocessor is connected with the temperature sensor and a setting key; the output end of the microprocessor is connected with a relay and a display; the output end of the relay is connected with a heating element; and the input ends of the temperature sensor, the relay, the microprocessor, the display and the setting key are connected with the output end of a power module respectively. On the one hand, the device directly measures the water temperature value and therefore error is reduced; and on the other hand, the device forms a closed-loop control system, and the microprocessor can adjust the heating power of the heating element through the relay according to the feedback of the real-time measurement value of water temperature, so that the control precision is higher and the comfort of the human body is greatly improved.

Description

technical field

[0001] The invention relates to the field of foot baths, in particular to a temperature control device for a foot bath and a temperature control method thereof. Background technique

[0002] At present, most of the foot baths on the market adopt the water bath method, and the water temperature can be adjusted between 40 and 50 degrees. The most important technical index of this kind of foot bath is the temperature control accuracy and stability. Most of the control is realized by bimetallic temperature control switch. Its advantages are cheap, stable, reliable, and simple circuit. The disadvantage is low precision. The main reason is that the measurement and control of this foot bath are the same component, so it cannot be installed in water. , generally installed on the heater or near the heater, so that what it measures is not the water temperature, but the temperature of the heater with a certain difference from the water temperature, so it is often set a...
