Problems solved by technology

[0004] In order to solve the problem in the prior art that when the energy storage power supply is used to provide additional power for the washing machine, the washing machine cannot select a specific heating program according to the capacity of the current energy storage power supply to protect the energy storage power supply. A washing machine with a heating tube with a power supply, using the control of the conduction angle of the thyristor, realizes the output control method between different power requirements of the washing machine washing program, and ensures the safety of the energy storage power supply

Embodiment 1

[0045] The heating tube is installed on the outer tub of the washing machine, the battery is 24V20AH, and the power of the heating tube is 1800W. When the user selects the high-temperature heating program to start during the washing process, the main control unit of the washing machine immediately switches the power input to the grid power input through the power switch unit (this process is a forced switch, that is, whether the current power input is battery or grid power). At the same time, the washing machine main control unit turns off the relay K1 (relays K1 and K2 are both off before use), and turns on the relay K2, so that the power of the grid power directly drives the full power output of the heating tube to achieve the purpose of rapid heating. During the heating process, the unit prompts the user with current heating information through the display screen, and the relay K2 is disconnected after the heating program is executed.

Embodiment 2

[0047] The heating tube is installed on the outer tub of the washing machine, the battery is 24V20AH, and the power of the heating tube is 1800W. When the user selects the low-temperature heating program during the washing process, the washing machine main control unit obtains the current battery power capacity value through the power analysis unit, including two results:

[0048] (1) The current remaining battery power is sufficient to support the low temperature heating program, and the washing machine main control unit switches the power input to the battery through the power switch unit (this process is a forced switch, that is, whether the current power input is the battery or the grid power). The main control unit of the washing machine controls the heating tube control circuit to turn off the relay K2 (K1 and K2 are usually off) and turn on the relay K1. At the same time, the control angle a corresponding to this low-temperature heating program controls the thyristor and th...

Abstract

The invention discloses a washing machine adjusting the heating power according to different input energies and a use method, which relate to the field of washing machines, wherein the washing machine comprises a washing machine main control unit, and an electric network source, an input interface, a stored energy power input interface, a heating pipe and a display which are respectively connected with the washing machine main control unit, a heating pipe control circuit is connected between the heating pipe and the washing machine main control unit, the heating pipe is a single adjustable heating pipe, and the heating pipe control circuit adjusts the power output of the heating pipe according to the power requirements of a washing procedure. The washing machine disclosed by the scheme adopts one heating pipe to provide heating efficiency support for two or various energies, when a user selects a high-temperature procedure, the electric network source is utilized to directly drive the heating pipe for full power output, when a low-temperature procedure is selected, a silicon controlled conduction angle alpha is adjusted and controlled for controlling the heating pipe to output the corresponding power, so the effect that one heating pipe can output different powers according to different requirements is realized.

Description

Technical field [0001] The invention relates to the field of washing machines, in particular to a heating control method of a washing machine using multiple energy sources and equipped with a heating device. Background technique [0002] In real life, the problem of lack of energy resources is the top priority for human survival. The existing energy sources such as water, coal, and oil will be exhausted in a few years according to the current speed and method of use. Therefore, various industries and fields are trying their best Look for alternative energy sources, or try to make reasonable use of existing energy sources. A variety of energy mixing methods have also appeared in the prior art to convert natural energy such as natural light and wind into energy that can be used by people, and the existing electrical equipment also adopts the working mode that saves energy as much as possible or improves energy. Utilization rate. The above-mentioned measures alleviated the energy ...
