Description

technical field

[0001] The invention relates to seat heating in the field of engineering machinery, in particular to a water heating circulation device, a seat heating system and a seat heating method. Background technique

[0002] At present, in the cold winter, in order to improve user experience, the seats of construction machinery (such as excavators) need to be heated. Generally speaking, the commonly used method of seat heating is to add an electric heating pad on the seat.

[0003] This method of heating the seat with an electric heating pad has the following technical problems:

[0004] First, high-power electrical appliances are likely to cause fire hazards and other safety hazards;

[0005] Second, increase fuel consumption;

[0006] Third, it is easy to cause damage to the excavator battery. Contents of the invention

[0007] In view of this, the present invention aims to propose a water heating circulation device, a seat heating system and a seat heating me...
