Description

Technical Field

[0001] The utility model relates to a salt adding device which is suitable for a water electrolysis device and belongs to the technical field of equipment for electrolysis process of chemical metallurgy department. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, dishwashers have come into people's sight. However, the existing dishwashers have limited improvement in cleaning ability by changing the structure. Using electrolyzed water instead of dishwashing powder can improve the cleaning ability of dishwashers. The technical solutions in this regard have also been applied more in the prior art. Refer to the Chinese utility model patent application with application number 202011152787.5 "Dishwasher with electrolytic disinfection structure" (application publication number CN 112137545 A); you can also refer to the Chinese utility model patent application with application number 202210609548.0 "A control method for an electrolyzed water generating device for an integrated water tank" (application publication number CN 115341625 A).

[0003] Electrolyzers need electrolytes during electrolysis. Considering that sodium chloride will produce a small amount of chlorine gas during the electrolysis process, sodium carbonate is used as the electrolyte. There are two problems with sodium carbonate as an electrolyte. First, the solubility of sodium carbonate is very low. If the user's sodium carbonate usage is to be met once a year, the sodium carbonate solution needs to be prepared in advance so that the total volume of the salt box reaches 7L. Second, sodium carbonate will condense into blocks at the bottom of the salt box and is difficult to dissolve, which is not conducive to electrolysis. A heating rod is required to assist dissolution, which is bound to increase manufacturing costs. Utility Model Content

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, the automatic salt feeding device in this embodiment includes a housing 1, a funnel 2, a screw 3, a stirring head 4 and a magnetic stirrer 5. The inner cavity of the housing 1 forms a brine chamber 11 and an installation chamber 12. The brine chamber 11 and the installation chamber 12 are separated by a partition 13, and the bottom of the installation chamber 12 is sealed with a bottom cover 14. The brine chamber 11 has an external water inlet port 15 for water inlet.

[0026] The funnel 2 is used to store salt. It is arranged on the upper end of the housing 1 and forms a discharge port at the bottom. A cover plate 21 is provided on the funnel port. The screw 3 can rotate and is arranged at the discharge port of the funnel 2. The outer wall has a spiral blade 31. The stirring head 4 is arranged at the bottom of the screw 3 and is located in the salt water chamber 11. It can be connected by screws. The stirring head 4 is provided with a stirring blade 41. The two ends of the stirring blade 41 have magnetic poles that cooperate with the magnetic stirrer 5 to drive the screw 3 to rotate. The magnetic stirrer 5 is arranged in the installation chamber 12 of the housing 1. After power is turned on, it can drive the screw 3 to rotate. The screw 3 can rotate forward and reverse relative to the funnel 2.

[0027] The housing 1 is provided with a salinity sensor, which is linked to the magnetic stirrer 5. Figure 4 As shown, a limiting channel 16 is provided in the salt water chamber 11, and a hole is opened at the bottom of the limiting channel 16 to communicate with the salt water chamber 11. The salinity sensor includes a Hall sensor 61 provided on one side of the housing 1 and a float 62 provided in the limiting channel 16. A magnet that can cooperate with the Hall sensor 61 to detect the salt concentration is provided in the float 62. The Hall sensor 61 detects the change in the magnetic field to determine the height of the float 62. An end cap 17 is provided at the top of the limiting channel 16 to limit the float 62 from rushing out of the limiting channel 16.

[0028] The housing 1 is provided with a first sensor 71 for detecting a high liquid level in the brine chamber 11 and a second sensor 72 for detecting a low liquid level in the brine chamber 11 , so as to control the water level in the brine chamber 11 .

[0029] After placing the salt in the funnel and connecting the hose to the water inlet port 15, the second sensor detects that the water level in the brine chamber is insufficient, and the pump pumps water into the brine chamber through the hose. When the first sensor detects that the liquid level has reached the high level, the pump stops working. The Hall sensor detects that the float position is not above the Hall sensor, indicating that the liquid salt concentration is insufficient. At this time, the magnetic stirring device is energized, and the screw rotates forward, driving the salt to fall. After rotating for a given time, it stops rotating, and the magnetic stirring device is energized in the reverse direction, and the screw rotates in the reverse direction. The stirring blades drive the liquid to rotate, which accelerates the dissolution of the salt. When the screw rotates in the reverse direction, the salt will not fall from the discharge port of the funnel into the brine chamber.

[0030] Embodiment 2: In this embodiment, a controller is provided on the housing, the signal input end of the controller is connected to the salinity sensor, and the command issuing end of the controller is connected to the magnetic stirrer 5. Other structures refer to Embodiment 1.
