Abstract

A water intake device for a washing apparatus, and a washing apparatus. The water intake device includes a first water intake assembly, a second water intake assembly, a communication assembly, a first flow limiting member and a second flow limiting member, the first flow limiting member and the second flow limiting member are arranged on the first water intake assembly in the direction of a water flow, and the flow rate of the first flow limiting member is less than the flow rate of the second flow limiting member. The communication assembly includes a communicating pipeline coupling the first water intake assembly and the second water intake assembly, and a connection control valve controlling the communicating pipeline to be connected or disconnected. The joint between the first water intake assembly and the communication pipeline is located between the first flow limiting member and the second flow limiting member.

First claim

What is claimed is:

1. A water inflow device for a washing apparatus, the water inflow device comprising: a body, a first water inflow assembly, a second water inflow assembly, a communication assembly, a first flow restriction member and a second flow restriction member that are arranged on the body; the first flow restriction member and the second flow restriction member are arranged in sequence on the first water inflow assembly in a water flow direction, and a flow rate of the first flow restriction member is smaller than a flow rate of the second flow restriction member; the communication assembly comprises a communication pipeline for communicating the first water inflow assembly with the second water inflow assembly, and an on-off control valve for controlling on and off of the communication pipeline; and a connection position between the first water inflow assembly and the communication pipeline is located between the first flow restriction member and the second flow restriction member.

2. The water inflow device according to claim 1 , wherein the first water inflow assembly comprises a first control valve and a first water inflow pipeline that are connected, the first flow restriction member is arranged inside an outlet of the first control valve, and the second flow restriction member is arranged inside the first water inflow pipeline.

3. The water inflow device according to claim 1 , wherein the second water inflow assembly comprises a second control valve and a second water inflow pipeline, and the second control valve comprises a first outlet and a second outlet, wherein the first outlet communicates with the communication pipeline, and the second outlet communicates with the second water inflow pipeline.

4. The water inflow device according to claim 3 , wherein a number of the second control valve and the second water inflow pipeline are both two, and the second control valves and the second water inflow pipelines correspond to each other in a one-to-one correspondence.

5. The water inflow device according to claim 4 , wherein the on-off control valve is a one-way check valve, and a number of the one-way check valve is two; the one-way check valves are respectively arranged inside the first outlets of the two second control valves to prevent water from entering the second control valves from the first outlets.

6. The water inflow device according to claim 4 , further comprising third flow restriction members, a number of which is two, and the third flow restriction members are respectively arranged inside the two second water inflow pipelines.

7. The water inflow device according to claim 2 , wherein the first control valve is a solenoid valve.

8. The water inflow device according to claim 3 , wherein the second control valve is a solenoid valve.

9. A washing apparatus, comprising the water inflow device according to claim 1 .

10. The washing apparatus according to claim 9 , wherein the washing apparatus is a washing machine which comprises a condenser and a detergent dispenser, the first water inflow assembly communicates with the condenser, and the second water inflow assembly communicates with the detergent dispenser.
