Embodiment 1

[0027] refer to figure 1 , figure 2 , this embodiment provides a foam overflow prevention device 2 for an intelligent washing machine, including a box body 21, a first connector 22 is provided on one side of the box body 21, and a second connector 23 is provided at the bottom of the box body 21; A connector 22 communicates with the second connector 23 through the connecting pipe 8; the first connector 22 is used for the detachable connection of the drain pipe 11 of the washing machine 1, and the second connector 23 is vertically detachably connected with an outlet pipe; An annular airbag 4 is installed at the bottom, and an inflatable nozzle 41 is arranged on the annular airbag 4, and an air pressure sensor 42 is also installed on the annular airbag 4; The output port of 32 is connected; the air pipe 7 is equipped with a one-way valve 71; the air bag is also connected with an exhaust pipe 7, and the other end of the exhaust pipe 7 stretches into the box body 21, and is provi...

Embodiment 2

[0033] This embodiment provides a method for controlling the foam overflow prevention device 2 described in Embodiment 1, including:

[0034] The controller 31 judges in real time whether the washing machine 1 has drainage through the output signal of the flowmeter 92; if so, it immediately controls the start of the air pump 32 to inflate the annular airbag 4 until the air pressure of the annular airbag 4 reaches a preset value;

[0035] Simultaneously, the controller 31 opens the second control valve 38, and the water in the water tank 34 enters into the annular channel through the discharge pipe 341, and then is guided by the annular shroud 61 to form an umbrella-shaped water flow;

[0036] At the same time, the controller 31 uses the output signal of the flow meter 92 to count the number of drains of the washing machine 1 within a same period; wherein, when the number of drains reaches the set value, the controller 31 immediately controls the third control valve 36 to close,...

Abstract

The invention discloses a foam spill-proof device of an intelligent washing machine. The device comprises a box body, a first connecting head is arranged on one side of the box body, and a second connecting head is arranged at the bottom of the box body; the first connecting head is communicated with the second connecting head through a connecting pipe; the first connecting head is used for the detachable connection of a drainage pipe of the washing machine, and the second connecting head is vertically and detachably connected with a water outlet pipe; a circular air bag is installed at the bottom of the water outlet pipe, an air nozzle is formed in the circular air bag, and an air pressure sensor is installed on the circular air bag; a controller and an air pump are installed in the box body, and the air nozzle is communicated with the outlet of the air pump through an air pipe; a one-way valve is installed on the air pipe; an air discharging pipe is connected with the air bag, the other end of the air discharging pipe extends into the box body, and a first control valve is arranged; the first control valve, the air pressure sensor and the air pump are electrically connected withthe controller. By means of the device, the overflowing of foams from sewers can be prevented to a certain extent.

Description

technical field [0001] The invention relates to the field of smart home technology, in particular to a foam overflow prevention device for a smart washing machine and a control method thereof. Background technique [0002] Through actual investigation and personal experience, it is found that when the automatic washing machine drains water for the first or second time, due to the excessive foam discharged, a large amount of foam will overflow from the nozzle of the sewer pipe, resulting in foam on the ground, and the user needs to It is very troublesome to clean up the ground. Contents of the invention [0003] In view of this, the first object of the present invention is to provide a foam overflow prevention device for an intelligent washing machine, which can prevent foam from overflowing from the sewer to a certain extent. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] A foam ov...
