Abstract
Description
Technical Field
[0001] This invention relates to a salt supply device used in electrolysis equipment, and also to an electrolysis mechanism. Background Technology
[0002] Currently, the commonly used carbonate electrolyte salt tanks for preparing alkaline electrolyzed water use a pre-mixed salt solution in a certain proportion. However, this method has a short lifespan and is not suitable for home use.
[0003] For household electrolysis systems (sodium carbonate), the method of users adding salt themselves presents a problem of frequent salt additions. Because household water electrolyzers are generally small in size, the salt tank is also small, so users need to add salt frequently to meet the needs of electrolysis.
[0004] The common way to solve the problem of frequent salt addition is to add a large amount of salt directly to the water (including the salt tanks with filters commonly used in dishwashers). However, this method inevitably has the following problems:
[0005] First, water is prone to overflow, which limits the amount of salt that can be added and requires a larger volume.
[0006] Second, electrolyte salts generate heat when they come into contact with water and tend to clump together, making further dissolution difficult and resulting in insufficient electrolytic conductivity.
[0007] Third, adding a large amount of salt to water will generate a lot of heat, causing the cavity to deform and a large amount of water to evaporate. Electrolyte salts, when exposed to water and generating heat, are prone to clumping, making further dissolution difficult and resulting in insufficient electrolytic conductivity.
[0008] Fourth, if the brine supernatant is in a supersaturated state, it is prone to crystallization and precipitation after temperature changes, affecting the conductivity and liquid volume required for electrolysis, and may also clog pipelines. Crystallization and agglomeration in the brine tank will cause volume expansion and deformation of the walls;
[0009] Fifth, whether the salt solubility meets the requirements for electrolysis can be used to start electrolysis and determine salt deficiency. Conventional methods achieve this through specific time / flow rates, which are prone to inaccurate control, leading to insufficient salt and waste. Directly adding salt to the sensor can easily cause it to fail due to agglomeration and crystallization.
[0010] Sixth, with the current common method of adding excessive salt, the water is not drained during the second addition of salt, and the above problems still exist;
[0011] Seventh, during the electrolysis process, the salt tank needs to be vented, which will take away the moisture in the salt tank. As crystals appear, the water level will drop further, affecting the continuation of electrolysis. Summary of the Invention
[0012] The first technical problem to be solved by the present invention is to provide a salt tank that does not require frequent salt addition and whose outer shell is not easily deformed, in view of the above-mentioned technical status.
[0013] The first technical problem to be solved by the present invention is to provide an electrolysis mechanism that does not require frequent salt addition and whose salt tank is not easily deformed.
[0014] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a salt tank for providing electrolytes, characterized in that it includes...
[0015] The outer shell has an internal cavity, a water inlet port, a water outlet port, an electrolysis water outlet port, and an electrolysis water return port;
[0016] A mesh bag, located in the internal cavity of the aforementioned outer shell, is used to hold excess salt powder. The mesh bag has a salt inlet formed on the outer shell. Water can pass through the mesh bag, but salt powder is difficult to pass through.
[0017] The aforementioned mesh bag and the inner wall of the outer shell form a water outlet area and a water return area, and there is a partition between the aforementioned water outlet area and the water return area. The aforementioned electrolytic water outlet port is opened in the water outlet area, and the aforementioned electrolytic water return port is opened in the water return area.
[0018] After an excess of salt powder is placed inside the mesh bag, a transparent liquid zone forms in the upper part of the inner cavity of the outer shell, and a white solid zone forms at the bottom of the mesh bag. This white solid zone contains undissolved salt powder. Below the transparent liquid zone, a crystalline zone containing transparent salt powder crystals forms within the inner cavity of the outer shell. The electrolytic water outlet port is located in the transparent liquid zone. The electrolytic water outlet port avoids the white solid zone and the crystalline zone, so that even if salt crystals precipitate, they will not clog the inlet and outlet pipes.
[0019] Furthermore, the electrolytic return water port is located in the transparent clear liquid area.
[0020] The outer casing has a vent port near the electrolysis return water port, and this vent port is equipped with a one-way vent valve. This reduces water evaporation, prevents external air from entering and reacting with the salt solution, thus preventing the salt solution from deteriorating, and also prevents the salt solution from leaking out after the salt tank is tilted. A waterproof and breathable membrane can be added to further improve the effect.
[0021] The housing is equipped with a liquid level sensor. The liquid level sensor can be linked with the water inlet valve to ensure that the water level is maintained at a certain level.
[0022] The partition has a longitudinal channel inside, and a salinity sensor is installed on the outer shell. The salinity sensor includes a Hall sensor located on the outside of the outer shell and a float located in the aforementioned longitudinal channel. The float contains a magnet that can cooperate with the Hall sensor to detect the salt concentration. The salinity sensing uses float TDS detection, is installed in the partition, has a compact structure, and also functions as a maximum liquid level sensor.
[0023] A weighing sensor is located at the bottom of the casing. When the amount of salt powder added reaches the set level, it can remind the user to stop pouring the salt powder.
[0024] The technical solution adopted by the present invention to solve the second technical problem mentioned above is as follows: an electrolysis mechanism with a salt tank, characterized in that it includes a salt tank, a heat exchanger, an electrolytic cell and a storage tank, wherein the electrolysis outlet and return water ends of the aforementioned salt tank are respectively connected to the anode inlet and anode outlet of the electrolytic cell through an outlet pipe and a return water pipe, respectively, the inlet and outlet of the aforementioned storage tank are respectively connected to the cathode outlet and anode inlet of the electrolytic cell, and the aforementioned heat exchanger is disposed on the return water pipe.
[0025] Preferably, a booster pump is installed on the outlet pipe. An inlet valve is installed at the inlet port of the salt tank. A level sensor is installed in the salt tank, and this level sensor is linked to the inlet valve. A drain pump is installed at the outlet port of the salt tank.
[0026] Compared with existing technologies, the advantages of this invention are as follows: The method of adding excess salt significantly reduces the volume of the salt tank while meeting the lifespan requirements, and also reduces the frequency of salt addition by the user; the mesh bag separates the salt from the inner wall of the outer shell, and the mesh bag is used to hold the salt; after adding excess salt, the generated heat and cooling will form crystals, and the mesh bag will deform due to the heat generated after the salt dissolves, but the outer shell wall will not deform, thus ensuring the stability and reliability of various sensors on the outer shell. Because there is a partition between the outlet and return water areas, the electrolysis return water port and the electrolysis outlet water port are not directly interconnected, ensuring a high-concentration output salt solution from the electrolysis outlet water port. When salt needs to be added, the wastewater in the salt tank is directly drained from the drain port, and all the salt in the salt box is poured in, without the need for user stirring, providing convenience for the user.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0034] like Figure 1 As shown, the electrolysis mechanism in this embodiment includes a salt tank 10, a heat exchanger 4, an electrolytic cell 5, and a storage tank 6. The electrolysis outlet 14 and the electrolysis return water end of the salt tank 10 are connected to the anode inlet and anode outlet of the electrolytic cell 5 via outlet pipe 31 and return water pipe 32, respectively. The inlet and outlet of the storage tank 6 are connected to the cathode outlet and anode inlet of the electrolytic cell 5, respectively. The heat exchanger 4 is mounted on the return water pipe 32. In this embodiment, the heat exchanger 4 can utilize the waste heat from the dishwasher chassis.
[0035] A booster pump 36 and a booster pump 37 are installed on the outlet pipe 31. An inlet valve 34 is installed at the inlet port 11 of the brine tank. A level sensor 17 is installed in the brine tank (see...). Figure 2 As shown, the liquid level sensor 17 is linked to the water inlet valve 34. The drain port of the salt tank is equipped with a drain pump 35.
[0036] Combination Figure 2 , Figure 3 and Figure 4 As shown, the salt tank 10 in this embodiment includes an outer shell 1 and a mesh bag 2. The outer shell 1 has an internal cavity, a water inlet port 11, a drain port 12, an electrolysis water outlet port 14, and an electrolysis water return port 13.
[0037] A mesh bag 2 is located inside the cavity of the outer shell 1 and is used to hold excess salt powder (such as sodium carbonate). The mesh bag 2 has a salt inlet 21 formed on the outer shell 1. The mesh bag 2 can supply water, but it is difficult for salt powder to pass through.
[0038] A water outlet area 1b and a water return area 1a are formed between the mesh bag 2 and the inner wall of the outer shell 1. A partition 1c is provided between the water outlet area 1b and the water return area 1a. The electrolysis water outlet port 14 is opened in the water outlet area 1b and is directly connected to it. The electrolysis water return port 13 is opened in the water return area 1a.
[0039] An exhaust port 15 is located on the outer casing 1 near the electrolysis return water port 13, and a one-way exhaust valve 16 is provided on the exhaust port 15. The partition 1c has a longitudinal channel inside, and a salinity sensor is provided on the outer casing 1. The salinity sensor includes a Hall sensor 18 located on the outside of the outer casing 1 and a float 181 located in the longitudinal channel. The float 181 contains a magnet that can cooperate with the Hall sensor 18 to detect the salt concentration. A weighing sensor 19 is located at the bottom of the outer casing 1.
[0040] Combination Figure 5 As shown, after placing excessive salt powder inside the mesh bag 2, a transparent clear liquid zone 1d is formed in the upper part of the internal cavity of the outer shell 1, a white solid zone 1f is formed at the bottom of the mesh bag 2, and a crystallization zone 1e containing transparent crystals is formed in the internal cavity of the outer shell 1 below the transparent clear liquid zone 1d. The electrolysis outlet port 14 is located in the transparent clear liquid zone 1d. The electrolysis return water port 13 is located in the transparent clear liquid zone 1d.
[0041] Softened water enters the brine tank through the inlet port, passing through the side and bottom mesh bags to contact the sodium carbonate salt. When the water reaches a certain level, the level sensor activates and closes the inlet valve. During electrolysis, water enters the anode of the electrolytic cell through the outlet port, and the electrolyzed water returns to the brine tank through the return port. Because there is a partition between the return and outlet ports, most of the water flows from the transparent clear liquid area within the mesh bags into the electrolysis outlet area, ensuring a high concentration of brine solution output. (Refer to the brine tank operation logic diagram.) Figure 6 As shown.
