Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, and in particular to a method for controlling conversion of regenerated water and stored water of a respirator. Background Art

[0002] Dishwashers are a common dishwashing equipment. Water softeners are important components used to soften hard water in dishwashers. The principle is to pass raw water through sodium cation exchange resins to exchange the hardness components of calcium and magnesium ions in the water with the sodium ions in the resin, so that the calcium and magnesium ions in the hard water are adsorbed in the resin, softening the hard water and thus avoiding the scaling of carbonate in the inner tank of the dishwasher.

[0003] As the calcium and magnesium ions in the resin increase, the efficiency of the resin in removing calcium and magnesium ions gradually decreases. When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to flush the resin layer with salt water in the salt chamber to replace the hardness ions on the resin. The resin is discharged out of the tank with the regeneration waste liquid, and the resin resumes its softening and exchange function.

[0004] With the increasing expansion of the dishwasher market, dishwashers are constantly innovating in terms of performance level. In particular, the requirements for energy consumption and water consumption of dishwashers are getting higher and higher. For this reason, dishwashers have built-in water tanks. However, dishwashers must also be equipped with a breather structure with a flow meter. 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 is not only large in size, but also has a very complex structure. It not only needs to connect the softener resin chamber and the softener salt chamber, but also requires a separate pipeline to connect the water in the water tank to the softener resin chamber or the dishwasher cavity container. The built-in water tank of the dishwasher has a complex installation structure, and the pipe connection between the softener and the dishwasher cavity and the water tank also increases the risk of water leakage. For example, a dishwasher disclosed in Chinese Patent No. ZL202211011994.8 includes an inner tank, a water tank, a first pipeline on-off regulator, a breather, a second connecting pipeline, a water supply pipeline and a second pipeline on-off regulator. The water tank is set close to the inner tank, and the breather is separated from the water tank. The dishwasher sets the water tank close to the inner tank so that the heat of the inner tank can be transferred to the water tank, thereby preheating the water stored in the water tank. The water stored in the water tank can be used for the next washing cycle or the next stage, so that the preheated water flows to the inner tank. Compared with normal temperature water flowing to the inner tank, the temperature is higher, which reduces the power consumption of the dishwasher when heating water, saves energy, and reduces costs. The water tank and the breather are set separately, which is convenient for disassembly and assembly of the water tank and the breather. In a usage scenario where a water tank is not needed, the connection between the breather and the water tank on the dishwasher can be removed, and the breather can directly supply water to the inner tank by adjusting the pipeline, thereby enhancing the flexibility of use of the dishwasher and simplifying the disassembly and assembly process. Summary of the invention

[0005] The present invention proposes a respirator regeneration water and storage water conversion control method, the respirator is provided with a softening water outlet chamber and a regeneration chamber which are independently arranged at intervals, and the respirator is also provided with a respirator solenoid valve for switching between the softening water outlet chamber and the regeneration chamber. When the respirator solenoid valve is in a closed state, the regeneration chamber of the respirator is used as a water storage tank, and a part of the liquid entering the respirator enters the softener through the softening water outlet chamber, and another part of the liquid entering the respirator enters the regeneration chamber and is stored in the regeneration chamber. The volume of the regeneration chamber is larger than the softening water outlet chamber.

[0006] A respirator regeneration water and storage water conversion control method designed for this purpose, the respirator is arranged on a dishwasher; the respirator has a softening water outlet chamber and a regeneration chamber which are independently arranged at intervals, a respirator solenoid valve is arranged at the connection between the softening water outlet chamber and the regeneration chamber of the respirator, and the respirator has a regeneration water use state and a storage water use state; The conversion control method includes the following steps: Step 1: Start the water inlet mechanism of the dishwasher, the dishwasher is filled with water for the first time, and the liquid flows to the breather according to the corresponding flow value; Step 2: When the dishwasher is filled with water for the first time, the solenoid valve of the breather is closed, and the water path connected to the output end of the regeneration chamber is disconnected by closing the corresponding solenoid valve, so that the softening water outlet chamber is not connected to the regeneration chamber, part of the liquid flowing to the breather enters the softening water outlet chamber, and another part of the liquid flowing to the breather enters the regeneration chamber, and the liquid is stored in the regeneration chamber of the breather; Step 3: When the dishwasher is filled with water again, the opening and closing of the breather solenoid valve is used to control the connection between the softening water outlet chamber and the regeneration chamber, control the output flow direction of the liquid stored in the breather, and then switch the use status of the breather.

[0007] In step 3, the respirator is switched to a regenerated water use state, the solenoid valve on the water path connected to the output end of the regeneration chamber is opened, the solenoid valve of the respirator remains closed, and the liquid stored in the respirator is output through the regeneration chamber to directly output the regenerated water on the regeneration chamber; The respirator is switched to the storage water use state, the respirator solenoid valve is opened, the solenoid valve on the water path connected to the output end of the regeneration chamber remains closed, and the liquid stored in the respirator enters the softening water outlet chamber through the regeneration chamber, and the liquid is finally output along the softening water outlet chamber.

[0009] In step three, liquid is stored in the regeneration chamber of the breather to be kept until the dishwasher is used next time. The liquid stored in the regeneration chamber absorbs the heat transferred to the breather, thereby increasing the temperature of the liquid stored in the regeneration chamber. When the dishwasher is used next time, the water inlet temperature of the dishwasher can be increased to reduce the energy consumption of the dishwasher.

[0010] In step three, the respirator is switched to the regenerated water use state, the solenoid valve on the water channel connected to the output end of the regeneration chamber is opened to the second set time, the solenoid valve on the water channel connected to the output end of the regeneration chamber is closed, the water inlet mechanism of the dishwasher is started, and the regeneration chamber of the respirator stores liquid again for the next use of the dishwasher.

[0012] The resin layer of the resin cavity is flushed with salt water to replace the hardness ions on the resin. The salt water flushing the resin cavity is discharged through the inner cavity of the dishwasher, or the salt water flushing the resin cavity directly flows through the resin cavity to a drainage pipe provided with a drainage solenoid valve.

[0013] In step 2, the resin chamber is connected to the softening water outlet chamber, and when the dishwasher is filled with water for the first time, the breather solenoid valve and the water softener solenoid valve are closed; the liquid entering the softening water outlet chamber enters the resin chamber to soften the liquid, and the softened liquid enters the inner cavity of the dishwasher.

[0014] In step three, the breather is switched to the regenerated water use state, the breather solenoid valve is opened, and the softener solenoid valve remains closed. The liquid stored in the regeneration chamber of the breather absorbs heat and enters the softening water outlet chamber. The liquid enters the resin chamber along the softening water outlet chamber to increase the water inlet temperature entering the inner cavity of the dishwasher.

[0015] In step one, the water inlet mechanism is opened to a set water inlet time, and then stops inletting water, or, when the liquid entering the respirator reaches a corresponding flow value, stops inletting water; a flow meter is provided in the respirator to calculate the liquid entering the respirator through the flow meter, and when the liquid entering the respirator and / or the liquid entering the inner cavity of the dishwasher reaches a corresponding flow value, the water inlet mechanism stops inletting water.

[0016] The beneficial technical effects of the present invention are as follows: The respirator is provided with a softening water outlet chamber and a regeneration chamber which are independently arranged at intervals. The respirator is also provided with a respirator solenoid valve for switching between the softening water outlet chamber and the regeneration chamber. When the respirator solenoid valve is in a closed state, the regeneration chamber of the respirator is used as a water storage tank. Part of the liquid entering the respirator enters the softener through the softening water outlet chamber, and another part of the liquid entering the respirator enters the regeneration chamber and is stored in the regeneration chamber.

The water tank structure installed inside the dishwasher is eliminated, the internal structure of the dishwasher is simplified, the overall volume of the dishwasher is reduced, the water path structure of the dishwasher is simplified, and the risk of water leakage in the dishwasher pipeline is reduced.

[0017] By adding a respirator solenoid valve, when the respirator solenoid valve is opened, the liquid in the regeneration chamber of the respirator flows to the softening water outlet chamber and enters the resin chamber of the water softener, and when the respirator solenoid valve is closed, the liquid entering the respirator can be stored in the regeneration chamber, realizing the effect of storing water. The respirator solenoid valve controls the liquid in the regeneration chamber of the respirator to flow to the salt chamber of the water softener to realize the effect of regenerated water. The complex water channel structure of the water tank is simplified, and the installation of the dishwasher is also simplified.

[0065] The working process of the above dishwasher breather 2 and water softener 6 is as follows: After the dishwasher 1 is started, when the dishwasher 1 is filled with water for the first time, the water inlet solenoid valve 29 is connected through the breather water inlet connector 17. Open, the respirator 2 is normally filled with water, during which the respirator solenoid valve 5 and the water softener solenoid valve 9 are not involved in the work. The liquid entering the respirator 2 enters the respirator water inlet 10 through the flow meter 12, part of the liquid flows to the softening water outlet chamber 3 and flows along the softening water outlet chamber 3 to the resin chamber 7 of the water softener 6 to soften the liquid, and the other part of the liquid flows to the regeneration chamber 4. Since the water softener solenoid valve 9 is not opened, the liquid in the regeneration chamber 4 cannot flow to the salt chamber 8 of the water softener 6, so that the regeneration chamber 4 can be used to store liquid. The regeneration chamber 4 of the respirator 2 is filled with water for subsequent use.

[0066] Before the dishwasher 1 is filled with water for the next time, the water in the regeneration chamber 4 of the breather 2 will absorb external heat (it can be understood that the breather is close to the outer side of the inner cavity of the dishwasher 1 and can absorb the heat generated by the operation of the dishwasher 1) to increase the temperature, and the water inlet temperature of the dishwasher will be increased during the next use, thereby reducing the energy consumption of the dishwasher 1. Before the dishwasher is filled with water for the next time, if the water storage function of the breather 2 is used, the breather solenoid valve 5 will work, and the valve core 19 of the breather solenoid valve 5 will be sucked in (the solenoid valve opens by magnetically adsorbing the valve core 19, which is the working principle of the existing solenoid valve), thereby opening the air chamber cavity outlet 18 of the breather 2, and releasing the stored water in the regeneration chamber 4 of the breather 2 into the resin chamber 7 of the water softener 6, and then into the spray arm of the dishwasher 1, and the spray arm sprays liquid toward the cavity of the dishwasher 1. After the stored water in the regeneration chamber 4 of the breather 2 is released to the specified time, the breather solenoid valve 5 will stop working, the air chamber cavity outlet 18 of the breather 2 will be closed, and the water inlet solenoid valve 29 will be opened to normally inlet water, thereby filling the regeneration chamber 4 of the breather 2 again.

[0067] If the respirator 2 is used for the regeneration water function, the water softener solenoid valve 9 is operated to open the water path between the salt chamber 8 of the water softener 6 and the regeneration chamber 4 of the respirator 2, and the stored water in the regeneration chamber 4 enters the salt chamber 8 of the water softener 6 through the salt chamber water inlet joint 14 and the salt chamber water inlet 16 of the water softener 6, and then the salt water flows to the resin chamber 7 for ion exchange, and the resin activity of the resin chamber 7 of the water softener 6 is re-stimulated (the principle of resin activity stimulating activity can be referred to the background technology of the specification of this application, which will not be described in detail here). Similarly, after the stored water in the regeneration chamber 4 of the respirator 2 is released to the specified time, the water softener solenoid valve 9 is stopped, the water path connecting the salt chamber 8 of the water softener 6 and the regeneration chamber 4 of the respirator 2 is closed, and the water inlet solenoid valve 29 is opened to allow water to flow normally, thereby filling the regeneration chamber 4 of the respirator 2 again. This realizes the conversion of the regeneration water and the stored water of the respirator 2.
