Description

Technical field

[0001] The utility model relates to a water softening device. [Background Technology]

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc., and the water softener is an important component of the dishwasher. Figure 1 As shown, existing water softeners usually take in water through a breather 20. There are two water paths inside the water softener. One path leads to the soft water chamber, where hardness components such as calcium and magnesium ions in the water are exchanged with sodium ions on the resin in the soft water chamber. In this way, hardness components such as calcium and magnesium ions in the water are adsorbed on the resin, softening the water, thereby preventing carbonate scaling in the dishwasher tank; the other path leads to the salt chamber. A channel is provided between the salt chamber and the soft water chamber to connect the salt chamber and the soft water chamber. A solenoid valve 30 is also provided on the side of the water softener to control the opening and closing of the channel. When the resin absorbs a certain amount of hardness components such as calcium and magnesium ions, the solenoid valve 30 can be activated to allow salt water in the salt chamber to flow into the soft water chamber to flush the resin, so that the hardness components such as calcium and magnesium ions on the resin are replaced and discharged from the water softener with the regenerated waste liquid. The resin then resumes its softening and exchange function. The water path is switched by the solenoid valve 30. However, some dishwashers do not require a breather due to cost and design requirements. The existing water softener can only adopt a single mode of water intake by the breather 20 and control by the external solenoid valve 30, which cannot meet the needs of some customers.

[0003] Therefore, the present invention is just based on above deficiency and produces. [Utility Model Content]

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1 to 7As shown, a water softening device includes a water softener 1 and a water inlet valve 2 detachably mounted on the water softener 1. The water inlet valve 2 is provided with a water inlet channel 21 for water flow, a first water outlet channel 22, a second water outlet channel 23, a first control valve 24 for controlling the flow of water between the first water outlet channel 22 and the water inlet channel 21, and a second control valve 25 for controlling the flow of water between the second water outlet channel 23 and the water inlet channel 21. The water softener 1 is provided with a softening chamber 11 for containing resin, a chamber for containing salt, and a chamber for containing molten salt. The salt chamber 12, the softening inlet channel 13 that can connect the first water outlet channel 22 and the softening chamber 11, the salt chamber inlet channel 14 that can connect the second water outlet channel 23 and the salt chamber 12, the connecting channel 15 that can connect the salt chamber 12 and the softening chamber 11, and the discharge port 16 that is connected to the softening chamber 11 and can allow softened water or waste brine flowing through the resin to flow out. A one-way valve assembly 3 is provided in the connecting channel 15 to control the opening and closing of the connecting channel 15 so that the brine in the salt chamber 12 can flow in one direction to the softening chamber 11. When it is necessary to soften the incoming water, water is input from the water inlet channel 21, and the first control valve 24 of the water inlet valve 2 controls the second water outlet channel 23 to be connected to the water inlet channel 21. Then, the water to be softened enters the softening chamber 11 of the water softener 1 through the softening inlet channel 13. The hardness components such as calcium and magnesium ions in the water are adsorbed on the resin, so that the water is softened and finally discharged from the discharge port 16; when the resin absorbs a certain amount of hardness components such as calcium and magnesium ions and the softening effect becomes weak, the second control valve 25 is started to connect the second water outlet channel 23 with the water inlet channel 21, and the water enters the salt chamber and contacts with the salt to form brine. The brine enters the connecting channel 15 and flows through the one-way valve assembly 3 and then flows into the softening chamber 11, so that the hardness components such as calcium and magnesium ions on the resin are replaced again. After flowing out from the discharge port 16 with the regenerated waste liquid, it is discharged from the water softener through the waste liquid pipe, and the resin has restored its softening exchange function.

[0024] Furthermore, the water softener 1 is provided with an installation opening 17 that communicates with the communication channel 15 and is used to install a solenoid valve to control the opening and closing of the communication channel 15. A sealing cap 4 is detachably connected to the installation opening 17, which can seal the installation opening 17 when the solenoid valve is removed. Compared to existing water softeners, the present invention eliminates the solenoid valve. Instead, the sealing cap 4 seals the installation opening 17 of the water softener 1, which is used to install the solenoid valve. Water is introduced through the water inlet valve 2, and a one-way valve assembly 3 is provided within the communication channel 15 to control the opening and closing of the communication channel 15, allowing the brine in the salt chamber 12 to flow one way into the softening chamber 11. This fulfills another customer need, thereby reducing costs and downsizing the water softening device. Furthermore, the water inlet valve 2, the one-way valve assembly 3, and the sealing cap 4 can be removed as needed, and the breather 20 and the solenoid valve 30 can be installed on the water softener to switch between the original modes. This provides for extreme flexibility and meets customer demand for solenoid valve selection.

[0025] Specifically, the one-way valve assembly 3 includes a valve seat 31 removably mounted within the connecting passage 15 and a one-way valve 32 mounted on the valve seat 31. By installing the one-way valve 32 within the connecting passage 15, the salt water in the salt chamber 12 can flow unidirectionally into the softening chamber 11 through the one-way valve 21, preventing the water in the softening chamber 11 from flowing back into the salt chamber 12. The water softener 1 includes a base 19, a softener body 18, and a top cover 10, which are assembled and fixed in sequence. The softening chamber 11, the salt chamber 12, the softening inlet channel 13, and the salt chamber inlet channel 14 are respectively formed by the base 19, the softener body 18, and the top cover 10. The connecting passage 15 is formed by the base 19 and the softener body 18. Removing the base 19 allows the one-way valve assembly 3 to be removed.

[0026] Specifically, the edge of the mounting opening 17 is provided with a boss 171, and the sealing cover 4 is provided with an elastic lock 41 that snaps onto the boss 171. Furthermore, a sealing ring 5 is provided at the connection between the water softener 1 and the sealing cover 4, which can be pressed against the water softener 1 by the sealing cover 4. When the elastic lock 41 of the sealing cover 4 snaps onto the boss 171, the sealing ring 5 is pressed tightly against the connection between the water softener 1 and the sealing cover 4, ensuring water leakage.

[0027] In the present utility model, a water softener 1 is provided with a feeding port 101 which is connected to the salt chamber 12 for supplying salt into the salt chamber 12. A salt chamber cover 6 is detachably connected to the feeding port 101. The salt chamber cover 6 is provided with a sealing plug 7 which is inserted into the feeding port 101 for sealing when the salt chamber cover 6 is covered on the feeding port 101.

[0028] Specifically, an annular flange 71 is provided at the upper end of the sealing plug 7, and a plurality of buckles 61 are provided on the inner top wall of the salt chamber cover 6, which are evenly distributed around the circumference and buckled onto the back of the annular flange 71. When the sealing plug 7 needs to be assembled onto the salt chamber cover 6, the end of the sealing plug 7 with the annular flange 71 can be pressed into the inner side of each buckle 61, so that the buckles 61 buckle onto the back of the annular flange 71, thereby fixing the sealing plug 7 to the inner side of the salt chamber cover 6.

[0029] In order to facilitate the installation and removal of the salt chamber cover 6, a plurality of circumferentially evenly distributed blocks 102 are provided on the outer edge of the introduction port 101, and a plurality of notches 62 corresponding one-to-one with the blocks 102 for insertion and a plurality of slots 63 connected one-to-one with the notches 62 and for the blocks to be inserted into after the salt chamber cover 6 is rotated are provided on the inner circumferential wall of the salt chamber cover 6. When installing the salt chamber cover 6, the notches 62 on the salt chamber cover 6 are first aligned one-to-one with the blocks 102, and the blocks 102 are inserted into the notches 62 one-to-one. Then, the salt chamber cover 6 is rotated so that the blocks 102 are stuck in the slots 63. In this way, the salt chamber cover 6 can be installed at the introduction port 101. When the salt chamber cover 6 needs to be removed, the salt chamber cover 6 is reversed so that the blocks 102 are moved to the notches 62, and the salt chamber cover 6 can be removed, which is very convenient.
