Problems solved by technology

[0003] When the washing machine is fed with water, the water inlet valve is generally used to enter the water. When the water is cut off, there will be negative pressure in the tap water pipes on some floors, so that the water mixed with laundry detergent in the water inlet pipes will flow into the tap water pipes in reverse, polluting the tap water source. Although the above-mentioned device can prevent the metering pump from being eroded by detergent and prolong the service life of the metering pump, the defect is that it does not have the function of anti-siphon, so it is impossible to avoid the water containing detergent from being sucked back into the water supply pipe network due to the siphon phenomenon, polluting the water source

Embodiment 1

[0031] refer to figure 1 , an anti-siphon detergent dispensing system of the present invention, the detergent dispensing system includes a water inlet valve 1, a water inlet channel 2, a liquid exchange chamber 4, a pump 5 and a detergent A box 6, and the detergent dispensing system also includes Including a waterway switcher 3, the water inlet channel 2 has an air vent A23 communicating with the atmosphere, the water inlet channel 2 includes a spray end 21, a receiving end 22, and is arranged between the spray end 21, the receiving end 22 and The air vent A23 communicated with the atmosphere, the spray end 21 is connected with the outlet of the water inlet valve 1, the receiving end 22 is connected with the waterway switcher 3, and the inlet of the water inlet valve 1 is connected to the water inlet, so The outlet of the water inlet valve 1 is connected to the waterway switcher 3 in series through the water inlet channel 2, and connected to the suction port of the pump 5 and ...

Embodiment 2

[0035] refer to figure 2 In this embodiment, on the basis of implementation 1, several detergent B boxes 10 are added, and the outlets of each detergent B box 10 are equipped with valves D12 respectively, and several valves D12 are arranged between the valve A7 and the liquid exchange chamber 4 valves C11, and the number of valves C11 is the same as the number of detergent B boxes 10, each detergent B box 10 is connected between valve A7 and liquid exchange chamber 4 through valve D12, or between valve A7 and adjacent valve C11 Between, or between the liquid exchange chamber 4 and the adjacent valve C11, or on the passage between any two adjacent valves C11.

Embodiment 3

[0037] refer to image 3 , The difference between this embodiment and Embodiment 1 is that the valve A7 and the valve B8 are combined into a two-position three-way valve A9, that is, the detergent A box 6 communicates with the liquid exchange chamber through the two-position three-way valve A9 The two-position three-way valve A9 is provided with a common port A91 connected with the liquid exchange chamber 4, a normal port B92 connected with the washing liquid inlet pipeline 14, and connected with the detergent A box 6 The normally closed port C93.

Abstract

The invention provides an anti-siphon detergent putting system which comprises a water inlet valve, a water inlet channel, a liquid exchange cavity, a pump and a detergent box A. The anti-siphon detergent putting system further comprises a water path switcher, wherein an outlet of the water inlet valve is connected with the water path switcher in series through the water inlet channel and then connected with a suction inlet of the pump and a connector end of the liquid exchange cavity in parallel; the other connector end of the liquid exchange cavity is connected with a valve A in series and then communicated with a washing liquid inlet pipeline; the detergent box A is communicated with the liquid exchange cavity through a valve B; a first through opening of the water path switcher is connected with the water inlet channel; a second through opening of the water path switcher is connected with the suction inlet of the pump and the liquid exchange cavity in parallel; a movable valve element capable of controlling the second through opening to be opened or closed is arranged in an inner cavity of the water path switcher; and outlet liquid of an outlet of the pump and outlet liquid of the washing liquid inlet pipeline finally flow into a washing barrel. The detergent putting system not only avoids the problem that water containing a detergent is sucked back to a water supply pipe network due to siphonage, but also ensures normal operation of liquid pumping work.

Description

【Technical field】 [0001] The invention relates to the technical field of detergent dispensing devices, in particular to an anti-siphon detergent dispensing system. 【Background technique】 [0002] Application number: The patent of CN201910336291.4 provides a detergent dispenser, which has a water inlet valve, a detergent box, a pump and a liquid exchange chamber, and the liquid exchange chamber is connected to the outlet of the water inlet valve and The suction port of the pump is connected, the detergent box is connected to the liquid exchange chamber after being connected to the valve, and the liquid exchange chamber is connected to the washing liquid inlet pipeline after being connected to the one-way valve A. This device can avoid washing The agent will flow through the metering pump, causing the metering pump to be easily damaged. [0003] When the washing machine is fed with water, the water inlet valve is generally used to enter the water. When the water is cut off, t...
