Description

FIELD The present invention belongs to the technical field of washing apparatus, and specifically provides a water inflow device for a washing apparatus, and a washing apparatus. BACKGROUND Washing apparatuses include washing machines, shoe washers and dish washers, etc., which generally wash with water, that is, water inflow is required in all of them during washing. With the continuous progress and development of science and technology, the functions of washing apparatuses are developing towards being more and more diverse, and some of these functions also need to be realized through water inflow. For example, for a washing machine with a clothing drying function, water needs to be supplied into a condenser during drying so as to condense drying air. Since different functions have different requirements on the flow rate of water inflow, in order to realize the functions related to water inflow, water inflow pipelines are generally added in the prior art. However, one pipeline is added with the addition of each function, which causes an overall structure to be bulky and leads to increase of the cost. Taking the washing machine as an example, in order to meet the continuous increase of user's requirements on use, a drying function is generally added in the existing washing machines. However, since the water supply of two different flow rates is required when supplying water to the condenser, a small-flow continuous water supply and a large-flow water supply are adopted, in which the small-flow continuous water supply provides condensed water, and the large-flow water supply provides functions such as flushing and drying condenser lint. Published Italian patent application ITTO20120794A discloses a solenoid valve assembly which is capable to provide two different flow-rates of water by arranging first and second solenoid valves hydraulically connected with each other between an inlet and an outlet of the solenoid valve assembly, a first hydraulic flow-rate regulating device disposed in or at the inlet, and a second hydraulic flow-rate regulating device disposed downstream of the first hydraulic flow-rate regulating device. Furthermore, published Chinese patent application CN109957942A discloses a water inlet valve with variable water outlet flow, wherein it comprises a valve body with a first water inlet channel and a second water inlet channel for independent water supply. The water inlet valve includes a communication pipeline connecting the first water inlet flow channel and the second water inlet flow channel. Meanwhile, a one-way conduction device is provided at the outlet end of the first water inlet flow channel or the second water inlet flow channel, and configured to keep on when the water enters the corresponding water inlet flow channel. Two independent water inflow pipelines are further added in the washing machine, and an independent solenoid valve is provided in each of these two water inflow pipelines to achieve water supply of different flow rates. The above valve assemblies make the water inflow structure to be bulkier and the manufacture cost to be higher. Accordingly, there is need in the art for a water inflow device for a washing apparatus and a washing apparatus to solve the above problem. SUMMARY In order to solve the above problem in the prior art, that is, to solve the problem that the water inflow structures of existing washing apparatuses are bulky and have a high cost, the present invention provides a water inflow device for a washing apparatus as defined in the appended set of claims. It can be understood by those skilled in the art that in the preferred technical solutions of the present invention, the first flow restriction member and the second flow restriction member are arranged in sequence on the first water inflow assembly in the water flow direction, the flow rate of the first flow restriction member is smaller than the flow rate of the second flow restriction member, the communication assembly communicates the first water inflow assembly with the second water inflow assembly, and the connection position between the first water inflow assembly and the communication assembly is located between the first flow restriction member and the second flow restriction member. Through such an arrangement, the first water inflow assembly can provide water supply of two flow rates; as compared with the prior art, the volume of the water inflow device is smaller and the manufacture cost is lower; in addition, by providing the first flow restriction member and the second flow restriction member, a more accurate flow control can be realized, and in practical applications, different models of flow restriction members can be substituted according to different functions, which is convenient and flexible, and has a wider application range. In addition, the washing apparatus further provided by the present invention on the basis of the above technical solutions, due to the adoption of the wate
