Embodiment 1

[0021] figure 1 It is a flow chart of the heating circuit automatic control method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the heating circuit automatic control method provided in this embodiment includes:

[0022] Step 11: Obtain the total detection value of the predetermined parameters to be detected in each heating circuit in at least two heating circuits.

[0023] Two or more heating circuits can be arranged in the same device, for example, two heating circuits can be arranged in a washing machine: a washing machine water heating circuit and a washing machine air-drying heating circuit. A certain predetermined parameter to be tested of each heating circuit can be detected separately to obtain the total detection value. The parameter to be detected can be determined according to actual needs. For example, the parameter to be detected can be current, and the current of each heating circuit of the device can be detected separately to o...

Embodiment 2

[0031] figure 2 It is a schematic diagram of an optional structure of the heating circuit automatic control device provided in Embodiment 2 of the present invention. Such as figure 2 As shown, the heating circuit automatic control device provided in this embodiment includes: a detection module 21 and a comparison control module 22 .

[0032] The detection module 21 is used to obtain the total detection value of the predetermined parameters to be detected in each heating circuit in at least two heating circuits. Optionally, two or more heating circuits can be set in the same device, for example, two heating circuits can be set in the washing machine: a washing machine water heating circuit and a washing machine air drying heating circuit. A certain predetermined parameter to be tested of each heating circuit can be detected separately to obtain the total detection value. The parameter to be detected can be determined according to actual needs. For example, the parameter to...

Embodiment 3

[0038] The present invention also provides a washing machine. The washing machine includes at least two heating circuits, and also includes any one of the above-mentioned automatic control devices for the heating circuits. The automatic control device for the heating circuits automatically controls each heating circuit, thus avoiding the The complete machine of the washing machine is damaged due to excessive load, which eliminates potential safety hazards.

[0039] Optionally, the washing machine includes two heating circuits: a first heating circuit and a second heating circuit. Such as image 3 As shown, the first heating circuit includes: a first relay and a first heater N1, the first relay includes a first relay body (including a first relay power coil K1 and a first diode D1), the The first relay main body K1 is provided with a first incoming terminal L1, a first normally closed terminal NC1 and a first normally open terminal NB1. The second heating circuit includes: a ...

Abstract

The invention relates to a method and device for automatically controlling heating circuits and a washing machine. The method for automatically controlling the heating circuits comprises the steps of acquiring a total detecting value of preset parameters to be detected of all the heating circuits in at least two heating circuits, comparing the total detecting value with a preset threshold value, controlling a part of the heating circuits to stop working or controlling all the heating circuits to stop working if the total detecting value is larger than the preset threshold value, and otherwise, maintaining the current working states of all the heating circuits. According to the method and device for automatically controlling the heating circuits and the washing machine, damage to the equipment due to oversize loads is avoided, potential safety hazards are avoided, and the overall safety performance of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control method and device for a heating circuit and a washing machine. Background technique [0002] At present, drum washing machines generally have two functions of water heating and air drying heating. The water heating circuit is used for heating the washing water of the washing machine, and the air-drying heating circuit is used for air-drying and heating the clothes and / or the washing drum. [0003] Under the normal operation of the washing machine, the water heating circuit and the wind heating circuit will not operate at the same time. If the two heating circuits operate at the same time due to abnormal settings of the washing machine, etc., a large operating current may be generated, which may damage the machine and pose a safety hazard. However, the prior art still lacks a corresponding security solution. Contents of the invention [0004] A ...
