To further illustrate the technical solution of the present invention, the following specific examples are provided as shown in fig. 1-2.

Example 1

In the present embodiment, there is provided an ozonated water production apparatus including: a housing 1; a controller 10 provided on the housing 1, an ozone generator 8 provided in the housing 1, a water tank 4, a water quality probe 3 provided in the water tank 4, and the like. The ozone generator 8 is used for generating ozone; the water tank 4 is connected with the ozone generator 8 and supplies water to the ozone generator 8; the water quality probe 3 is used for acquiring water quality hardness information in the water tank 4; a controller 10 for controlling the current supplied to the ozone generator 8 based on the water hardness information to control the ozone production rate.

The ozone water preparation device solves the problem that the concentration of ozone water is uncontrollable when ozone water is prepared according to different water qualities; the purpose of stabilizing the concentration of the ozone water is achieved by controlling water flow, current and the like in the preparation process.

In some optional manners, the ozonated water production apparatus further includes: water pipe 5, water pump 6 and flowmeter 7. In order to realize the water supply to the ozone generator 8, the first end of the water pipe 5 is connected into the water tank 4, and the second end of the water pipe 5 is connected with the ozone generator 8; the water pump 6 is arranged on the water pipe 5, and the water pump 6 in the water tank 4 can be sent to the ozone generator 8 through the water pump 6; the flowmeter 7 is provided on the water pipe 5 and is capable of detecting the flow rate of water in the water pipe 5.

The ozone water preparation device can adjust the water flow of the water supply part of the ozone generator 8, can also supply water with a certain fixed water flow, and can realize flexible adjustment to ensure the concentration of the ozone water and the preparation efficiency of the ozone water when being matched with the ozone preparation speed of the ozone generator 8.

In some alternatives, the bottom of the water tank 4 is formed with a sink 4.1 to provide the lowest water level at the bottom of the water tank 4. Preferably, the first end of the water pipe 5 extends inside the water tank 4 into the sink tank 4.1.

To ensure more accurate detection of the water quality in the water tank 4, it is preferable to dispose the water quality probe 3 at the bottom of the water tank 4 near the first end (water pipe inlet) of the water pipe 5, because the water quality at different positions in the water tank 4 may vary. That is, the water quality probe 3 is brought as close as possible to the inlet side of the water pipe 5 so that the water quality entering the water pipe 5 is detected in real time. It should be noted that, in other alternative modes, the water quality probe 3 may also be disposed in the water pipe 5 for directly collecting the water hardness information in the water pipe 5.

In some optional manners, the ozonated water production apparatus further includes: the liquid level probe 2 is arranged at the bottom of the water tank 4 and is used for acquiring liquid level information in the water tank 4; and the ejector 9 is arranged at the second end of the water pipe 5, and is used for ejecting the ozone water prepared by the water passing through the ozone generator 8.

In some optional manners, the ozonated water production apparatus further includes: a water quality adjusting and purifying device. This purifier is adjusted to quality of water can purify the water in the water tank 4, avoids influencing the concentration of ozone water when because of quality of water hardness is great.

For example, the hardness of water is controlled to be 0-500 mg/L in this embodiment; correspondingly, the current value of the ozone generator 8 is controlled between 100mA and 500 mA. When the hardness of the water in the water tank 4 is detected to exceed 500mg/L, the water quality adjusting and purifying device can be started to treat the water in the water tank 4; when the hardness of the water in the water tank 4 is detected to be lower than 300mg/L, the water quality adjusting and purifying device stops working.

The start condition and the stop condition of the water quality adjusting and purifying device can be set to other water hardness standards, and specific values can be set according to actual needs, for example, the water quality adjusting and purifying device is started when the water hardness is set to be over 400mg/L, and the water quality adjusting and purifying device is stopped when the water hardness is set to be under 200mg/L, and the like, which are not listed here.

Ozone has a disinfecting and sterilizing effect, and therefore, is used in many places. At present, the ozone water generator on the market mainly electrolyzes water through two positive and negative polar plates to generate ozone which is dissolved in water and then sprayed out for disinfection and sterilization. However, the concentration of ozone water prepared by different water qualities is unstable and is easily affected by the hardness of water, resulting in too high concentration or too low concentration. Too high concentration is harmful to human body, and too low concentration can not achieve the effect of disinfection and sterilization. Therefore, it is very important to control the ozone water concentration. Because the invention improves the ozone water preparation device and optimizes the ozone water preparation control method, the ozone water concentration can be controlled compared with the common ozone water generator, and the bad results caused by insufficient concentration or overhigh concentration of the ozone water due to the change of the water quality are avoided.

Example 2

In the present embodiment, there is provided an ozone water production control method which can be used for controlling the ozone water production apparatus in embodiment 1 to produce ozone water. The control method comprises the following steps: collecting water hardness information of water supplied to the ozone generator 8; and selecting a corresponding current gear for supplying to the ozone generator 8 according to the water quality hardness information so as to control the ozone preparation speed.

The method for automatically adjusting the concentration of the ozone water realizes the controllability of the concentration of the ozone water and solves the problem that the concentration of the ozone water prepared by the ozone generator 8 is uncontrollable due to the change of the water quality.

In some alternatives, selecting a corresponding current tap for the ozone generator 8 in combination with the water hardness information comprises: if the hardness of the water is higher, the current value corresponding to the current gear supplied to the ozone generator 8 is higher; conversely, the smaller the hardness of the water, the smaller the current value corresponding to the current level to be supplied to the ozone generator 8.

In some optional manners, the control method further includes: the water in the control water tank 4 is supplied to the ozone generator 8 at a preset supply flow rate to match the production rate of ozone. Such as: in one of the simpler adjustment modes, the supply of water to the ozone generator 8 is controlled to a constant supply flow. At this time, the ozone generation rate is controlled by adjusting the current of the ozone generator 8, so that the ozone water concentration can be accurately controlled.

A specific operation principle of the ozone generator will be described below with reference to the above control method in this embodiment.

First, the controller 10 prestores current values I required by the ozone generator 8 corresponding to various water hardness S. For example, water hardness S1 corresponds to current value I1, water hardness S2 corresponds to current value I2, and so on. The concentration of ozone water generated by these one-to-one correspondence relations is a certain value Q. Meanwhile, the 6 water pump 6 works at a fixed frequency, and the water flow is constant.

Secondly, when the machine is powered on and started, the liquid level probe 2 detects that water exists in the water tank 4, the water quality probe 3 detects the hardness of the water, the water quality probe 3 detects that the water quality is fed back to the controller 10, and the controller 10 reads the pre-stored water hardness S information according to the detected hardness. If: the currently detected hardness is S0, and the water hardness S is compared according to the information pre-stored in the controller 10. If S0 is equal to S0, the hardness S0 is matched with the current I0 according to the information pre-stored in the controller 10, and then the controller 10 controls the current value to the ozone generator 8 to be I0.

Thirdly, the water pump 6 starts to work at this time, water is pumped to the water pump through the lowest water level in the water tank 4 and flows to the ozone generator 8 through the water pipe 5, the water is made into ozone water after passing through the ozone generator 8, and the ozone water is sprayed out through the sprayer 9 for sterilization and disinfection.
