[0039] Example 1

[0040] The present embodiment provides a dishwasher disinfection component. In one implementation, the dishwasher disinfection component includes a water softener 1, an electrolyzer 2, and a gas transmission structure.

[0041] The water softener 1 has a water inlet, a water outlet, a salt chamber, and a soft water chamber. The salt chamber is a closed chamber and has a gas inlet 11 and a salt water outlet 12. The water inlet is connected to a first solenoid valve. The first solenoid valve has a first open state that connects the water inlet with the salt chamber to input water into the salt chamber. The first solenoid valve also has a second open state that connects the water inlet with the soft water chamber to input water into the soft water chamber. When the first solenoid valve is in the second open state, water is softened in the soft water chamber and then enters the inner tank of the dishwasher to perform normal dishwashing.

[0042] like Figure 1 As shown, the electrolyzer 2 is connected to the brine outlet 12 through a first pipeline 3, a second solenoid valve 4 is provided on the first pipeline 3, an electrolysis chamber and an electrolysis electrode are provided in the electrolyzer 2, and after the sodium chloride solution enters the electrolysis chamber, sodium hypochlorite can be generated for disinfection under the action of the electrolysis electrode.

[0043] The gas delivery structure is connected to the gas inlet 11 through the second pipeline 6 and is used to deliver the gas into the salt chamber so that the brine in the salt chamber is delivered to the electrolyzer 2 .

[0044] In the dishwasher disinfection component provided in this embodiment, the salt chamber of the water softener 1 itself stores a large amount of salt. When the first solenoid valve is in the first open state, water can be supplied to the salt chamber to store saturated salt water in the salt chamber. When disinfection is required, the second solenoid valve 4 is opened, and the gas supply structure works to supply gas to the salt chamber. Since the salt chamber is a closed chamber, under the action of gas pressure, the saturated salt water in the salt chamber enters the electrolyzer 2 through the first pipeline 3 for electrolysis to generate a disinfectant. The disinfectant can be used to disinfect the dishwasher with a good disinfection effect.

[0045] On the basis of the above-mentioned embodiments, in one embodiment, the gas transmission structure is a plunger pump 5 , and the plunger pump 5 can realize reciprocating motion, so that the gas can continuously enter the plunger pump 5 and enter the salt cavity through the plunger pump 5 .

[0046] Specifically, the plunger pump 5 is arranged outside the main structure of the dishwasher. The main structure of the dishwasher refers to a shell, on which there is a door, and the inner tank and the spray arm assembly are both located inside the shell.

[0047] Based on the above implementation, in one implementation, Figure 2 As shown, the plunger pump 5 includes a pump body 51, a piston, and a driving structure. The pump body 51 has a cavity, and one end of the pump body 51 is provided with an air inlet and an air outlet, the air inlet is provided with an air inlet one-way structure, the air outlet is provided with an air outlet one-way structure, and the air outlet is connected to the second pipeline 6. The pump body 51 in this embodiment is a cylindrical structure with a hollow cavity inside. The air inlet and the air outlet are arranged at the first end of the body 511, and the air inlet and the air outlet are both tubular structures; the piston is arranged in the cavity and is in sealing contact with the cavity wall of the cavity; the driving structure is used to drive the piston to move in the cavity.

[0048] The pump body 51 includes a main body 511 and a cover body 512 disposed on the main body 511 to facilitate installation of the piston into the cavity. The cover body 512 is provided with a mounting hole, and the driving structure is connected to the piston through the mounting hole.

[0049] In the dishwasher disinfection assembly provided in this embodiment, when the piston moves toward the second end of the pump body 51, the gas enters the cavity through the air inlet; when the piston moves toward the first end of the pump body 51, the gas enters the salt cavity through the air outlet and the second pipeline 6, and presses the sodium chloride solution in the salt cavity into the electrolyzer 2.

[0050] On the basis of the above-mentioned embodiments, in one embodiment, the piston is a nut 54, and the driving structure includes a motor 52 and a screw 53. The motor 52 is arranged outside the pump body 51; the screw 53 is fixedly connected to the motor shaft of the motor 52, and the screw 53 is located in the cavity, and the nut 54 is arranged on the screw 53, and the screw 53 has an external thread, and the nut 54 has an internal thread that matches the external thread of the screw 53. When the screw 53 rotates under the drive of the motor 52, the nut 54 moves on the screw 53, and the moving direction of the nut 54 can be controlled by controlling the forward or reverse rotation of the motor 52, thereby controlling the air intake and exhaust of the plunger pump 5. In an alternative embodiment, the driving structure can use an electric push rod, which is connected to the piston to drive the piston to move back and forth.

[0051] On the basis of the above embodiments, in one embodiment, the air intake one-way structure includes an air intake one-way sheet 55 disposed in the cavity and suitable for blocking the air intake port, and the air intake one-way sheet 55 is hinged to the cavity. When air is taken in, the gas enters the cavity, causing the air intake one-way sheet 55 to rotate toward the inside of the cavity, thereby opening the air intake port. In an alternative embodiment, a one-way valve may be disposed at the air intake port as the air intake one-way structure.

[0052] On the basis of the above-mentioned embodiments, in one embodiment, the one-way gas outlet structure includes a one-way gas outlet sheet 56 disposed at the outer end of the gas outlet and suitable for blocking the gas outlet, and the one-way gas outlet sheet 56 is hinged to the gas outlet. When exhausting, the gas enters the salt cavity from the cavity, and under the movement of the piston, the gas moves outward and impacts the one-way gas outlet sheet 56, and the one-way gas outlet sheet 56 rotates outward to open the gas outlet. In an alternative embodiment, a one-way valve can be disposed at the gas outlet as the one-way gas outlet structure.

[0053] Based on the above embodiment, in one embodiment, the second solenoid valve 4 is disposed on the electrolyzer 2, so that the disinfectant produced by the electrolyzer 2 can be prevented from flowing back into the first pipeline 3. In an alternative embodiment, the second solenoid valve 4 can be disposed on the first pipeline 3.

[0054] On the basis of the above embodiment, in one embodiment, the gas inlet 11 is arranged at the top of the salt chamber. In an alternative embodiment, the gas inlet 11 can be arranged on the side wall of the salt chamber near the top.

[0055] Based on the above embodiment, in one embodiment, the dishwasher disinfection assembly further includes a controller, which is used to control the second solenoid valve 4 to close after the second solenoid valve 4 is opened for a preset time. The preset time may be a preset required disinfection time.

[0056] Based on the above embodiment, in one embodiment, the electrolyzer 2 is arranged outside the inner tank, and the disinfectant generated by electrolysis of the electrolyzer 2 is suitable for flowing into the inner tank. By arranging the electrolyzer 2 outside the inner tank, the inside of the dishwasher can be disinfected without changing the internal structure of the dishwasher. In an alternative embodiment, the electrolyzer 2 can be arranged in the inner tank.

[0057] The dishwasher disinfection component provided in this embodiment, when working normally, the controller controls the first solenoid valve to switch to the second open state, and the water enters the inner tank of the dishwasher after being softened by the soft water chamber to perform normal dishwashing. When disinfection is required, the controller controls the second solenoid valve 4 to open, and the plunger pump 5 to open, and the plunger pump 5 introduces compressed air from the top of the salt chamber into the salt chamber, so that the salt water in the salt chamber is pressed out from the bottom and flows into the electrolyzer 2 for electrolysis, and the electrolyzer 2 introduces the sodium hypochlorite solution formed by electrolysis into the dishwasher to participate in disinfection. When the opening time of the second solenoid valve 4 reaches the preset time, the controller controls the second solenoid valve 4 to close, and the plunger pump 5 returns to its initial position to prepare for the next disinfection. The first solenoid valve on the water softener 1 is opened to the first open state, and water is added to the salt chamber to keep the salt chamber full of water.
