Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] see figure 1 As shown, the present invention discloses a washing machine 100 , including a complete machine 10 , a spray gun assembly 20 matched with the complete machine 10 , and a liquid storage tank 30 for providing cleaning fluid to the complete machine 10 .
[0032] see figure 1 As shown, the complete machine 10 includes a pump head assembly 11 , a control assembly 12 for controlling the operation of the pump head assembly 11 , a first communication unit 13 , a first power supply 14 and a housing 15 . The pump head assembly 11 includes a high pressure pump 111 and a motor 112 driving the high pressure pump 111 to work. The input end of the high-pressure pump 111 is connected to the liquid storage tank 30 to extract the liquid in the ...

The invention provides a cleaning machine and a control method thereof. The cleaning machine comprises a complete machine and a spray gun assembly; the complete machine comprises a pump head assembly,a control assembly for controlling the pump head assembly to work, and a first communication unit; the spray gun assembly comprises a spray gun matched with the pump head assembly and a second communication unit arranged on the spray gun; when the spray gun is opened, the second communication unit directly or indirectly communicates with the first communication unit, so that the control assemblycontrols the pump head assembly to work; and when the spray gun is closed, the second communication unit directly or indirectly communicates with the first communication unit, so that the control assembly controls the pump head assembly to stop working. According to the cleaning machine and the control method thereof, compared with the prior art, the cleaning machine achieves synchronous opening and closing of a host machine and the spray gun through the communication assemblies, and therefore the problem of large current caused by the fact that an existing cleaning machine does not stop whenthe spray gun is closed is solved.
Description
technical field [0001] The invention relates to a washing machine and a control method of the washing machine. Background technique [0002] The host switch and the spray gun switch of the existing washing machine are independent. When the spray gun is turned off, although the spray gun cannot spray water, the main engine is still in normal working condition at this time, that is, the plunger of the high-pressure pump is still constantly reciprocating. Since the high-pressure water cannot be ejected from the spray gun, the water pressure in the cylinder wall of the high-pressure pump gradually increases. When the pressure acting on the pressure relief valve is greater than the upper limit of the pressure relief valve, the pressure relief valve opens to form an internal circulation between the pressure relief channel and the high-pressure pump, so that the pressure in the cylinder wall of the high-pressure pump returns to normal. At this time The motor driving the high-pres...
