In FIGS. 20-22, the heating tube 2-2 is disposed on the aluminum plate 2-3, the aluminum plate 2-3 is disposed on the outer bottom or outer sidewall of the inner tub and fixed by soldering, and the heating tube 2-2 is used to transfer heat to the aluminum plate 2-3 in a power-on state to heat the inner tub; the fuse link 1-7 and the temperature controller 1-6 are used for carrying out overheat protection on the heating tube 2-2 and are arranged at the accessory of the heating tube 2-2, and the difference between the protection temperature value and the protection effect is different. The fuse link 1-7 can not recover to work again after acting, and is provided with a fixed protection temperature value, and when the temperature of the heating tube 2-2 exceeds the temperature value, the fuse link 1-7 is fused to form open-circuit protection; the temperature controller 1-6 also has a fixed protection value, when the temperature of the heating tube 2-2 exceeds the protection value, the temperature controller 1-6 acts to turn off the heating circuit, but the temperature controller 1-6 can resume working, it also has a fixed recovery temperature value, when the temperature of the heating tube 2-2 is reduced to the recovery temperature, the temperature controller 1-6 resumes working, the circuit returns to the on-state again; the temperature sensors 1-9 are typically thermistors for real-time monitoring of ambient temperature to provide feedback signals for logical judgment, control and output from the control circuit board. The control circuit board is provided with a programmable logic controller, a relay, a controlled silicon and other elements and is used for carrying out logic control on heating and whipping of the soymilk machine 4.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, many simple modifications can be made to the technical solution of the invention. Including each of the specific features, are combined in any suitable manner. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
