Detailed Implementation Methods

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 6 As shown, a dishwasher breather includes a housing 1, which is formed by a base 18 and a faceplate 19. The housing 1 contains a water inlet channel 11 for water inflow, a water chamber 12 communicating with the water inlet channel 11, a first water outlet channel 13, a second water outlet channel 14, a first connecting port 15 connecting the water chamber 12 and the first water outlet channel 13, and a second connecting port 16 connecting the water chamber 12 and the second water outlet channel 14. The housing 1 is equipped with a solenoid valve 2, which includes a valve core 21 with one end extending between the first connecting port 15 and the second connecting port 16, and a sealing plug 22 driven by the valve core 21 to close either the first connecting port 15 or the second connecting port 16. When valve 2 is energized, the valve core 21 retracts into the solenoid valve 2, and the sealing plug 22 moves away from the first connecting port 15 and abuts against the side of the second connecting port 16, causing the first connecting port 15 to open and the second connecting port 16 to close. At this time, water can continuously flow to the brine chamber of the water softener, causing the calcium, magnesium ions and other hardness components on the resin to be replaced, and the resin regains its softening and exchange function. When the solenoid valve 2 is de-energized, the valve core 21 extends outward from the solenoid valve 2, and the sealing plug 22 moves away from the second connecting port 16 and abuts against the side of the first connecting port 15, causing the second connecting port 16 to open and the first connecting port 15 to close. At this time, water can continuously flow to the softening chamber of the water softener, soften it, and then enter the inner tank of the dishwasher.

[0023] This utility model has a simple structure and flexible use, and can meet the needs of customers to select the water outlet of the breather through the solenoid valve. When the resin of the water softener needs to be regenerated, the solenoid valve 2 is energized, and the first connecting port 15 connects the water chamber 12 and the first water outlet channel 13, so as to controllably and continuously supply water to the brine chamber of the water softener, which meets the water volume required to complete the resin regeneration in one go.

[0024] Specifically, the valve core 21 comprises a valve core body 211 and a mounting connector 212 detachably connected to the valve core body 211, and the sealing plug 22 is detachably mounted on the mounting connector 212. The split structure of the valve core body 211, the mounting connector 212 and the sealing plug 22 facilitates production and assembly. The electromagnetic valve 2 further comprises a coil device 23 capable of generating a magnetic field force to attract the valve core body 211 after being energized, and a spring 24 for pressing the valve core body 211 to reset. When the electromagnetic valve 2 is energized, the magnetic force generated by the coil device 23 can attract the valve core body 211 into the electromagnetic valve 2 to drive the mounting connector 212 and the sealing plug 22. When the electromagnetic valve 2 is de-energized, the spring 24 presses the valve core body 211 to drive the mounting connector 212 and the sealing plug 22 to reset.

[0025] Specifically, one end of the valve core body 211 is provided with a connecting column 2111 and a positioning boss 2112 arranged on the connecting column 2111, and one end of the mounting connector 212 is provided with a side opening clamping groove 2121 for clamping the positioning boss 2112 and an avoiding opening 2122 in communication with the side opening clamping groove 2121 and for clamping the connecting column 2111 when the positioning boss 2112 is clamped into the side opening clamping groove 2121.

[0026] Further, the avoiding opening 2122 is U-shaped, and two opposite inner walls of the avoiding opening 2122 are respectively provided with limiting protrusions 2123 for clamping the connecting column 2111 when the connecting column 2111 is clamped into the avoiding opening 2122. During installation, the positioning boss 2112 is clamped into the side opening clamping groove 2121 and then pressed into position, so that the connecting column 2111 reaches the bottom of the U-shaped avoiding opening 2122, and the two limiting protrusions 2123 clamp the connecting column 2111 from the outside to prevent the connecting column 2111 from being pulled out of the avoiding opening 2122.

[0027] Specifically, one end of the mounting connector 212 is provided with a plug-in column 2124, and the sealing plug 22 is provided with a plug-in groove 221 for inserting the plug-in column 2124. During installation, the sealing plug 22 is plugged into the mounting connector 212, which is very convenient to install and disassemble.

[0028] In the utility model, the shell 1 is provided with a through hole 17 in communication with the second water outlet channel 14 for the one end of the valve core 21 to extend into from the shell 1, the through hole 17, the second communication opening 16 and the first communication opening 15 are coaxially arranged and communicated. The through hole 17 is arranged on the side wall of the shell 1, when the electromagnetic valve 2 is installed on the side of the shell 1, the one end of the mounting connector 212 on the valve core body 211 can pass through the through hole 17 and the second communication opening 16 in sequence to reach the water cavity 12, and the sealing plug 22 mounted on the mounting connector 212 is located between the first communication opening 15 and the second communication opening 16 and selectively blocks the first communication opening 15 or the second communication opening 16 under the driving of the mounting connector 212 and the valve core body 211 to switch the waterway direction.

[0029] The utility model still has the flowmeter being located in the water inlet channel 11, the breathing mouth being connected with the atmosphere, the detour channel being connected in the water inlet channel 11 and the water chamber 12, the pressure regulating chamber being connected with the breathing mouth and the detour channel, and the flow control member in the detour channel can increase the speed when water flows. Due to the effect of the detour channel and the flow control member, the water is accelerated when passing through the flow control member, and the water quickly cuts through the upper convex and arc-shaped detour channel, so that the water cannot flow out of the detour channel and can maintain the function of being connected with the atmosphere. When negative pressure is generated in the water inlet channel 11, the water in the water softener will have a tendency of backflow due to siphon, but the air in the atmosphere can enter the detour channel through the pressure regulating chamber due to the connection between the pressure regulating chamber and the atmosphere, so that the negative pressure of the water inlet channel 11 is balanced, and the water in the water softener and the water outlet channel is prevented from backflow.
