In order to accurately prepare the required high-concentration concentrated water (in this embodiment, the concentration of NaCl in the concentrated water is 0.1 wt%), in this embodiment, a temperature monitoring device 713 for monitoring the temperature of the saturated brine is provided in the salt tank 71, the electrolysis chamber 74 further includes a current monitoring device 740 for monitoring the current between the cathode and the anode, and the integrated water tank has a controller, and the temperature monitoring device 713, the current monitoring device 740, the first valve 77 and the second valve 78 are electrically connected to the controller, so that the controller can receive signals collected by the temperature monitoring device 713 and the current monitoring device 740 and control the on/off of the first tap water pipe 711, the second tap water pipe 721, the saturated brine pipe 712, the first soft water pipe 722 and the second soft water pipe 723. In this embodiment, the temperature monitoring device 713 is a temperature probe and is installed at the bottom inside the salt tank 71; the current monitoring device 740 is a current monitor, is installed outside the case 741, and is electrically connected to the anode 743 and the cathode 744, thereby feeding back the current applied to the anode and the cathode in real time.
The design idea is as follows: the water provided by the salt tank 71 is saturated saline water, the water provided by the softening tank 72 is soft water (the concentration of NaCl in the soft water is 0), the volume of the thick water tank 73 is constant, the concentration of NaCl in the saturated saline water can be calculated through the temperature measured by the temperature monitoring device 713 because the concentration of NaCl in the saturated saline water is related to the temperature (see table 1 for details), then the introduction ratio of the saturated saline water to the soft water is determined, during actual operation, the supply time of the saturated saline water and the soft water is controlled by switching the first valve 77, the concentration of the thick water can be preliminarily realized to be about 0.1wt%, but because the flow of tap water fluctuates, the volume of the liquid obtained according to the flow time mode has certain errors, and the mode can only roughly adjust the concentration of NaCl in the thick water. During the operation of the electrolysis chamber 74, the current monitoring device 740 can monitor the current between the cathode and the anode in real time, when the concentration of NaCl in the concentrated water is 0.1wt%, the current measured by the current monitoring device 740 is 2A, when the concentration is higher than 2A, the concentration is higher, when the concentration is lower than 2A, the concentration is lower, when the concentration is higher, the second tap water pipe 721 can be opened by switching the first valve 77, a certain amount of soft water can be supplemented until the current is reduced to 2A, when the concentration is lower, the first tap water pipe 711 can be opened by switching the first valve 77, a certain amount of saturated salt water can be supplemented until the current is increased to 2A, and therefore the concentration of NaCl in the concentrated water can be finely adjusted.

in this process, the concentration of the concentrated water is coarsely adjusted by: the temperature monitoring device 713 measures the temperature of the saturated salt water in the salt tank 71, the controller calculates the concentration C of the saturated salt water according to the temperature measured by the temperature monitoring device 713, then the volume ratio V of the saturated salt water and the soft water introduced into the concentrated water tank 73 is determined according to the target concentration Ct of the concentrated water, and V = Ct/(C-Ct);
the concentration of the concentrated water is finely adjusted by the following method: the current monitoring device 740 detects a real-time current I between the cathode and the anode in the electrolysis chamber 74, the controller judges the magnitude between the real-time current I and a target current It, if I is smaller than It, saturated salt water is supplemented into the concentrated water tank 73, and if I is larger than It, soft water is supplemented into the concentrated water tank 73;
(2) A second working mode: when the user instructs to supply soft water to the washing machine, the first valve 77 and the second valve 78 are switched to the third state, tap water enters the soft water tank 72 through the second tap water pipe 721 to be softened into soft water, and then the soft water enters the washing machine 5 through the second soft water pipe 723;
(3) The third working mode is as follows: when the user instructs to supply the acid water to the watering can 14, the third valve 79 is switched to connect the acid water pipe 751, and the acid water in the acid water tank 75 is pumped into the watering can 14 through the acid water pipe 751 by the second delivery pump 7511, so that the acid water can be used for the sterilization of the surface of the toy, the appliance and the like;
(4) The fourth working mode: when a user indicates to supply alkaline water to the sprinkling can 14, the third valve 79 is switched to enable the alkaline water pipe 761 to be communicated, and under the action of the second delivery pump 7511, the alkaline water in the alkaline water tank 76 is pumped into the sprinkling can 14 through the alkaline water pipe 761 and can be used for cleaning greasy dirt on the surface of a table board, a range hood and the like.
It can be seen that in the present embodiment, the salt tank 71 and the water softening tank 72 are shared by the electrolyzed water generating apparatus 7 and the cleaning machine 5, so that the electrolytic chamber 74 can generate acidic and alkaline electrolyzed water without increasing the cost, and the diaphragm and the electrodes are not easily blocked by scale, thereby greatly prolonging the service life.
The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter collectively referred to as a first portion and a second portion, respectively), i.e., a fluid (gas, liquid or a mixture of both) can flow from the first portion along a flow path or/and be transported to the second portion, and may be a direct communication between the first portion and the second portion, or an indirect communication between the first portion and the second portion via at least one third member, such as a fluid channel, e.g., a pipe, a channel, a conduit, a flow guide, a hole, a groove, or a chamber that allows a fluid to flow therethrough, or a combination thereof.
