Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a water inlet control method for a dishwasher breather. Background Art

[0002] With the ever-expanding dishwasher market, dishwashers are constantly innovating in terms of performance levels; in particular, the energy consumption and water consumption requirements for dishwashers are getting higher and higher; for this reason, dishwashers have adopted built-in water tanks; however, dishwashers must also be equipped with a breather structure with a flow meter, and the coexistence of the water tank and the breather has become the core of contemporary dishwashers; however, the current dishwasher water tank with a flow meter, in addition to being large in size, is also quite complex in structure, not only requiring connection to the softener resin chamber and the softener salt chamber, but also requiring a separate pipeline to connect the water in the water tank to the softener resin chamber or the dishwasher chamber container; its installation structure is complex, and it also increases the risk of water leakage when the dishwasher is filled with water.

[0003] Therefore, further improvements are necessary. Summary of the invention

[0004] The purpose of the present invention is to provide a water inlet control method for a dishwasher breather which has simple control, low risk of water leakage, low energy consumption, simplified water channel structure and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] A method for controlling water inlet of a dishwasher breather designed for this purpose, the breather includes a breather body, characterized in that: a water inlet, a water inlet channel and a water storage and regeneration chamber are arranged on the breather body, the water inlet is connected to the water inlet channel and the water storage and regeneration chamber respectively, and the water inlet channel is connected to the resin chamber; The water inlet control method comprises the following steps: A. When the dishwasher is filled with water for the first time, external water enters the respirator body through the water inlet at the corresponding flow value; B. External water flows synchronously in two ways in the main body of the respirator. One way flows into the resin chamber of the water softener through the water inlet channel, and then flows into the dishwasher cavity. The other way flows into the water storage and regeneration chamber and fills up the water storage and regeneration chamber to form stored water. C. Before the dishwasher is filled with water next time, the stored water in the water storage and regeneration chamber is released; The stored water flows into the resin chamber of the water softener and then into the dishwasher cavity; Alternatively, the stored water flows into the salt chamber of the water softener, and then the brine in the salt chamber is squeezed into the resin chamber to perform ion exchange.

[0006] In step C, after the stored water in the water storage regeneration chamber is released for a specified time, the release of the stored water is stopped, and then the respirator body is refilled with water.

[0007] A first electromagnetic valve is arranged on the main body of the respirator, and the opening and closing of the water storage regeneration chamber and the resin chamber are controlled by opening and closing the first electromagnetic valve.

[0008] The water softener is provided with a second solenoid valve, and the opening and closing of the water storage regeneration chamber and the salt chamber are controlled by opening and closing the second solenoid valve.

[0009] In step B, the first solenoid valve does not work to cut off the water storage regeneration chamber and the resin chamber; the second solenoid valve does not work to cut off the water storage regeneration chamber and the salt chamber.

[0010] In step C, if the first solenoid valve is working and the second solenoid valve is not working, the stored water in the water storage regeneration chamber is released and flows into the resin chamber of the water softener.

[0011] In step C, if the second solenoid valve is working and the first solenoid valve is not working, the stored water in the water storage regeneration chamber is released and flows into the salt chamber of the water softener.

[0012] In step C, after the stored water in the water storage and regeneration chamber is released for a specified time, the first solenoid valve stops working to cut off the water storage and regeneration chamber from the resin chamber.

[0013] In step C, after the stored water in the water storage regeneration chamber is released for a specified time, the second solenoid valve stops working to cut off the water storage regeneration chamber and the salt chamber.

[0014] The water inlet is connected to the water inlet valve; in step A, the water inlet valve is opened to allow external water to enter the respirator body through the water inlet, and when the external water entering the respirator body reaches a corresponding flow value, the water inlet valve is closed.

[0015] According to the water inlet control method of the dishwasher breather of the present invention, after external water enters the breather body, one way of water flows into the resin chamber of the water softener through the water inlet channel, and the other way of water flows into the water storage regeneration chamber and fills up the water storage regeneration chamber to form stored water. Then, before the dishwasher is ingested with water next time, the stored water in the water storage regeneration chamber is released into the resin chamber or the salt chamber to achieve the use effect of stored water or the use effect of regenerated water, so that the water storage regeneration chamber can replace the built-in water tank of the traditional dishwasher, simplifying the complex water channel structure of the traditional built-in water tank, and also simplifying the installation structure of the dishwasher, and no separate pipeline is required to be connected to the water softener resin chamber or the dishwasher cavity container, thereby reducing the risk of water leakage when the dishwasher is ingested with water.
