Embodiment 1

[0049] A kind of water inlet device that can drop detergent, see Figure 4 , Figure 5 , Figure 7 , Figure 10 , Figure 11 , the main channel 11 and the flushing and liquid inlet channel 12 are connected in parallel on the water inlet channel. The outlet direction of the water inlet valve is connected with a Venturi tube 7, the flushing and liquid inlet channel is connected with a liquid collection chamber 5 in the direction of the outlet of the flushing electromagnetic water inlet valve, and the flushing and liquid inlet channel is connected between the flushing electromagnetic water inlet valve and the liquid collection chamber. There is a two-position three-way electromagnetic switch valve 9, and the inlet B direction of the two-position three-way electromagnetic switch valve is connected with a detergent B box 10, and the flushing and liquid inlet channel is located between the flushing electromagnetic water inlet valve and the two-position three-way electromagnetic s...

Embodiment 2

[0064] A kind of water inlet device that can put detergent in this example is different from the above example in that the detergent box is a pull-out detergent box 24, see Figure 23 , Figure 24 A dual-channel transition joint 25 is installed at the detergent A outlet 2011 and the detergent B outlet of the box body 20, the outlet of the detergent A box and the outlet of the detergent B box correspond to one of the two inlets of the transition joint respectively, and the transition The two outlets of the connector communicate with the detergent A inlet 2103 and the detergent B inlet 2102 of the switching valve respectively. Other constructions are the same as the above example.

Abstract

Provided is a water inlet device capable of feeding detergents. The water inlet device capable of feeding detergents can feed detergents accurately and effectively, and metal parts are not corroded. The water inlet device capable of feeding detergents comprises a main channel (11), and a Venturi tube (7) is connected to the main channel (11), wherein the main channel (11) is connected with a main electromagnetic water inlet valve (1), and a flushing and liquid inlet channel (12) is connected in parallel with a water delivery channel in the direction of the inlet of the main electromagnetic water inlet valve; the flushing and liquid inlet channel (12) is connected with an electromagnetic flushing water inlet valve (2) and a liquid collection chamber (5) located in the direction of the outlet of the electromagnetic flushing water inlet valve (2), and an one-way valve A (3) and a detergent A box (4) which is arranged in the direction of the inlet of the one-way valve A (3) are connected to the portion, between the electromagnetic flushing water inlet valve (2) and the liquid collection chamber (5), of the flushing and liquid inlet channel (12) in a branch mode; a liquid outlet passage (14) is connected to a portion between the outlet of the liquid collection chamber and the negative pressure port of the Venturi tube, the liquid outlet passage is connected with a flow sensor (6), and the outlet of the main channel is connected to a wash bucket. The water inlet device capable of feeding detergents is used as a water inlet and detergent feeding device for a washing machine.

Description

technical field [0001] The invention relates to a device for injecting liquid preparations, in particular to a device for automatically injecting detergent for washing machines. Background technique [0002] With the acceleration of the pace of life and the continuous improvement of consumers' energy-saving awareness, users pay more attention to energy-saving and convenient home appliances when purchasing homes and appliances. As a household appliance with high frequency of household use, washing machine is energy-saving and convenient has become an important factor for customers to choose and buy. Washing machines with the function of automatically adding detergent are therefore more and more popular among users. However, most of the ordinary washing machines on the market currently add detergent manually when washing clothes, and it is difficult to control the dosage. The effect is poor and the cleaning ratio is low; when the amount of detergent is too large, it not only ...
