Description

Technical Field

[0001] The present invention relates to the technical field of disinfection and sterilization equipment, and particularly relates to a disinfection water generating device and a control method. Background Art

[0002] Ozone can instantaneously kill bacteria and viruses due to its extremely strong oxidizing property. Since its reaction products are water and oxygen, it can not only quickly kill bacteria but also cause no pollution to the environment, and is gradually recognized and used by people.

[0003] The disinfection water generating devices in the prior art generally include an ozone generator, a water inlet pipe and a water outlet pipe connected to the ozone generator. The ozone generator generally includes a container, an electrolyte membrane disposed in the container, an anodic electrolysis cavity and a cathodic electrolysis cavity respectively formed on both sides of the container. An anode and an anodic electrolysis catalytic layer are disposed in the anodic electrolysis cavity. A cathode and a cathodic electrolysis catalytic layer are disposed in the cathodic electrolysis cavity. The ozone generated by the ozone generator can be dissolved in water to generate disinfection water.

[0004] However, the solubility of ozone is greatly affected by the temperature and TDS value of water. The disinfection water generating devices in the prior art generally increase the solubility of ozone in water by raising the water temperature. However, when the water temperature decreases, the conductivity of water also decreases, sacrificing the efficiency of electrolytic ozone and limiting the increase in the solubility of ozone in disinfection water.

[0064] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0065] Embodiment 1

[0066] Figure 1 Schematically shows the disinfectant water generating device according to Embodiment 1 of the present invention. As Figure 1As shown, the disinfectant water generating device of the embodiment mainly includes an ozone generator 1, a first temperature control device 31, a water tank 2 and a second temperature control device 32. Among them, the ozone generator 1 is suitable for generating ozone. The first temperature control device 31 is connected to the ozone generator 1, and is suitable for cooling or heating the water in the ozone generator 1 so that the TDS of the water in the ozone generator reaches a preset TDS value. The water inlet of the water tank 2 is suitable for being connected to a water source, and the air outlet of the ozone generator 1 is connected to the air inlet of the water tank 2. The second temperature control device 32 is connected to the water tank 2, and is suitable for cooling or heating the water in the water tank 2 so that the solubility of ozone in water reaches a preset solubility.

[0067] It can be seen from the above technical scheme that the disinfectant water generating device 100 of Example 1 divides the preparation of ozone and the preparation of disinfectant water by dissolving ozone into two different areas. This enables the first temperature control device 31 in the ozone generator 1 to adjust the water temperature in the ozone generator 1 so that the TDS value of the water in the ozone generator 1 reaches a preset TDS value. The preset TDS value is preferably a TDS value that can make the water have the highest conductivity, which makes the water in the ozone generator 1 have a higher conductivity, and the ozone generator 1 has a higher efficiency in preparing ozone. The second temperature control device 32 can adjust the water temperature in the water tank 2 so that the ozone in the ozone generator 1 can have a higher solubility in water. Among them, the first preset temperature and the second preset temperature are one in the range of 3-7°C, and the other is in the range of 50-60°C. When the water temperature is in the range of 3-7°C, the low temperature can prolong the half-life of ozone, thereby improving the disinfection and sterilization effect on conventional easily inactivated microorganisms. When the water temperature is within the range of 50-60°C, the TDS value of the water is large and the conductivity is good. At this time, the electrolysis efficiency is high and the electrolysis power required can be smaller, which can reduce energy consumption. Therefore, the disinfection water generating device 100 of Example 1 has a high efficiency in generating ozone and can make ozone be more fully dissolved in water. Therefore, the ozone in the disinfection water prepared by the ozone generator of the present invention has a high solubility and a long half-life, and has a good disinfection and sterilization effect.

[0068] In addition, the ozone generator of the present invention has a simple structure, is easy to manufacture, and is convenient for implementation, promotion and application.

[0069] The applicant has found that when the TDS value of water increases, the conductivity of water also increases. Generally speaking, TDS=KX+B.

[0070] Where K is the conductivity of water;

[0071] X is in the range of 0.55-0.7;

[0072] B is a constant, and the specific value of B can be obtained through experiments.

[0073] The first temperature control device 31 can be selected as an electric heating wire, a PTC heating element, etc. Preferably, in this embodiment, as Figure 2 shown, the first temperature control device 31 includes a semiconductor temperature controller 312 that can both heat up and cool down water. Preferably, the first temperature control device further includes a heat dissipation housing and a heat dissipation fan. Among them, the heat dissipation housing is arranged on the outer wall of the first water pipe, and the heat dissipation fan is arranged on the heat dissipation housing, which can cool or heat the water in the first water pipe to make the TDS value of the water reach the preset TDS value.

[0074] Preferably, the heat dissipation housing includes a fixing part 311 and a heat dissipation plate 313. Among them, a through hole for accommodating the water outlet pipe is arranged in the center of the fixing part 311, and the hole wall of the through hole fits with the pipe wall of the water outlet pipe. The heat dissipation plate 313 is vertically arranged on the outer side wall of the fixing part 311, and a plurality of heat dissipation plates 313 are parallel to each other and arranged at intervals. At the same time, the heat dissipation fan is arranged on the side of the heat dissipation plate 313 away from the fixing part 311.

[0075] At the same time, a heat sink and a heat dissipation fan 314 are connected to the other side of the semiconductor temperature controller 312. It can improve the heat dissipation effect of the temperature control device to ensure cooling, or the heating effect lasts. Among them, the heat sink is made of aluminum fins with better heat conduction effect.

[0076] The ozone generator can be selected to include a container, an electrolyte membrane arranged in the container, an anode electrolysis chamber and a cathode electrolysis chamber respectively formed on both sides of the container. An anode and an anode electrolysis catalytic layer are arranged in the anode electrolysis chamber. A cathode and a cathode electrolysis catalytic layer are arranged in the cathode electrolysis chamber. The materials of the anode electrode catalytic layer are commonly boron-doped diamond, SnO2, which are corrosion-resistant, have a high oxygen evolution potential, and good electrical conductivity; the materials of the cathode electrode catalytic layer are commonly corrosion-resistant materials such as stainless steel and nickel, with a lower hydrogen evolution potential; the electrolyte membrane is a proton exchange membrane, and H + reaches the cathode through the proton exchange membrane to undergo a reduction reaction to generate hydrogen.

[0077] The second temperature control device 32 can adjust the water temperature in the water tank, so that the ozone in the ozone generator 1 can have a higher solubility in water and a longer half-life. Therefore, the ozone concentration in the disinfected water generated by the ozone generator 1 in this embodiment 1 is higher, and the disinfection and sterilization effect is better.

[0078] The second temperature control device can be selected as a heat exchanger, a liquid cooling device, an air cooling device, etc. Preferably, in this embodiment, the second temperature control device includes a semiconductor temperature controller 312 that can both heat and cool water. Preferably, the second temperature control device further includes a heat dissipation housing and a heat dissipation fan. Wherein, a second pipeline is connected between the water outlet of the ozone generator and the water inlet of the water tank. The heat dissipation housing is arranged on the outer wall of the second pipeline, and the heat dissipation fan is arranged on the heat dissipation housing, which can cool or heat the water in the second pipeline to make the TDS value of the water reach the preset TDS value.

[0079] Preferably, the heat dissipation housing includes a fixing part 311 and heat dissipation plates 313. Wherein, a through hole for accommodating the water outlet pipe is arranged in the center of the fixing part 311, and the hole wall of the through hole fits with the pipe wall of the water outlet pipe. The heat dissipation plates 313 are vertically arranged on the outer side wall of the fixing part 311, and a plurality of heat dissipation plates 313 are parallel and spaced from each other. At the same time, the heat dissipation fan is arranged on the side of the heat dissipation plates 313 away from the fixing part 311.

[0080] At the same time, a heat sink and a heat dissipation fan 314 are connected to the other side of the semiconductor temperature controller 312. It can improve the heat dissipation effect of the temperature control device to ensure cooling, or the heating effect lasts. Among them, the heat sink is made of aluminum fins with better heat conduction effect.

[0081] Preferably, in this embodiment, the water outlet of the water tank is connected to a third water pipe, and the third water pipe is suitable for discharging disinfected water outward. A nozzle or a spray head can be selected on the side of the third water pipe away from the water tank, which can evenly discharge the disinfected water in the water tank outward. In other embodiments, the end of the third water pipe away from the water tank can also be selected to be connected to an atomizing nozzle, which can atomize the water in the water tank, thereby expanding the disinfection and sterilization range of the disinfected water generating device. When the end of the third water pipe away from the water tank is connected to a pointed nozzle, the disinfected water generating device can also be used as a dental irrigator.

[0082] In this embodiment, the disinfected water generating device 100 preferably further includes a first detection device 41 and a control module. Wherein, the first detection device 41 is connected to the ozone generator 1 and is suitable for detecting the TDS value of the water in the ozone generator 1. The control module is communicatively connected to the first detection device 41 and the first temperature control device 31, and is suitable for controlling the first temperature control device 31 to cool or heat the water in the ozone generator 1 according to the detection result of the first detection device 41. The control module can judge whether the TDS value of the water in the ozone generator 1 reaches the preset TDS value according to the detection result of the first detection device 41. And when the water in the ozone generator 1 does not reach the preset TDS value, the first temperature control device 31 is controlled to heat or cool the water to make it reach the preset TDS value. The first detection device 41 is preferably but not limited to a TDS probe, etc.

[0083] In this embodiment, the disinfected water generating device 100 preferably further includes a second detection device 42. The second detection device 42 is connected to the water tank 2 and is adapted to detect the ozone solubility of the water in the water tank 2. The control module is communicatively connected to the second detection device 42 and the second temperature control device 32 and is adapted to control the second temperature control device 32 to cool or heat the water in the water tank 2 according to the detection result of the second detection device 42.

[0084] The control module can judge whether the water in the water tank 2 reaches the preset ozone solubility according to the detection result of the second detection device 42, and when the water in the water tank 2 does not reach the preset ozone solubility, control the second temperature control device 32 to lower the water temperature in the water tank 2, thereby increasing the ozone solubility to improve the disinfection effect of the disinfected water. The control module may include a programmable logic control component (such as a PLC or a CPU), a memory, and electronic components connected to the programmable logic control component, etc., which are well known to those skilled in the art and will not be elaborated here. The second detection device 42 is preferably a dissolved ozone detector.

[0085] Optionally, the water inlet of the water tank 2 is directly connected to a water source. Preferably, in this embodiment, the disinfected water generating device 100 further includes a first water pipe 5 which is adapted to be connected to the water source. The water inlet of the ozone generator 1 is connected to the first water pipe 5. The water outlet of the ozone generator 1 is connected to the water inlet of the water tank 2. This enables, when adjusting the water level in the ozone generator 1, the excess water to be drained into the water tank 2 and made into disinfected water, avoiding waste of water resources. In addition, the ozone dissolved in the water during the electrolysis process also enters the water tank 2, enabling full utilization of the ozone.

[0086] In this embodiment, the disinfected water generating device 100 further includes a third detection device 43 and a water inlet pump 6. Among them, the third detection device 43 is connected to the ozone generator 1 and is adapted to detect the water level in the ozone generator 1. The water inlet pump 6 is arranged in the first water pipe 5. The control module is connected to the third detection device 43 and the water inlet pump 6 and is adapted to control the water inlet pump 6 to allow the water in the water source to flow into the ozone generator 1 when the third detection device 43 detects that the water level in the ozone generator 1 is lower than a preset first water level. When the third detection device 43 detects that the water in the ozone generator 1 is higher than a preset second water level, the water inlet pump 6 is turned off, and the preset second water level is higher than the preset first water level. Therefore, the control module can timely control the water inlet pump 6 to supply water to the ozone generator 1 when the water level in the ozone generator 1 is low to ensure the smooth progress of the ozone production operation. The third detection device 43 is preferably but not limited to a liquid level gauge, a combination of a float and a proximity switch, or a combination of a float and a reed switch, etc.

[0087] The preset first water level and the preset second water level can be selected according to actual usage requirements. For example, the highest water level that can ensure that the ozone generator 1 will not overflow is taken as the first preset water level. The lowest water level at which the ozone generator 1 can electrolyze water and generate ozone is taken as the second water level.

[0088] In this embodiment, the disinfected water generating device 100 further includes a first switching element 71. The first switching element 71 is disposed between the water outlet of the ozone generator 1 and the water inlet of the water tank 2. The first switching element 71 is communicatively connected to the control module. The control module can control the first switching element 71 to connect the water outlet of the ozone generator 1 and the water inlet of the water tank 2 when the third detection device 43 detects that the water level in the ozone generator 1 is equal to or higher than the preset second water level. Therefore, when the water level in the ozone generator 1 is too high, the excess water can be discharged into the water tank 2 and made into disinfected water, avoiding waste of water resources.

[0089] The control module can also control the first switching element 71 to cut off the connection between the water outlet of the ozone generator 1 and the water inlet of the water tank 2 when the third detection device 43 detects that the water level in the ozone generator 1 is equal to or lower than the preset second water level, thereby avoiding the water level in the ozone generator 1 being too low due to excessive drainage. The first switching element 71 is preferably but not limited to an electromagnetic valve.

[0090] In this embodiment, the disinfected water generating device 100 further includes a fourth detection device and a second switching element 72. The fourth detection device is connected to the ozone generator 1 and is adapted to detect the air pressure in the ozone generator 1. The second switching element 72 is disposed between the gas outlet of the ozone generator 1 and the gas inlet of the water tank 2. The control module is connected to the second switching element 72 and is adapted to control the second switching element 72 to connect the gas outlet of the ozone generator 1 and the gas inlet of the water tank 2 when the air pressure in the ozone generator 1 reaches the preset first air pressure.

[0091] Therefore, when the ozone generated by electrolysis causes the air pressure in the generator to reach a predetermined first air pressure, the control module can control the second switching element 72 to connect the air outlet of the ozone generator 1 to the air inlet of the water tank 2. This can not only make the ozone generated by the ozone generator 1 be filled into the water to produce an aeration effect, thereby increasing the solubility of ozone in the water, but also effectively prevent the liquid in the mixer from flowing back. In addition, since hydrogen and ozone are actually generated during the electrolysis process, and hydrogen is lighter in mass and located at the top layer of the air, through the setting of the pipeline position and the on-off control, the purity of the actual ozone can be improved to a certain extent. The predetermined first air pressure value varies with the concentration of ozone in the disinfected water to be obtained, and can be obtained through preliminary tests. For example, in this embodiment, the first air pressure value can be 7 Pa greater than the air pressure value in the generator when ozone is present under steady-state conditions at normal temperature without electrolysis. The fourth detection device is preferably but not limited to a pressure sensor, and can also be selected as a pressure braking valve that can be opened when the pressure in the ozone generator reaches the first pressure.

[0092] Embodiment 2

[0093] Embodiment 2 relates to a control method for a disinfected water generating device 100. As Figure 3 shown, the disinfected water generating device 100 mainly includes an ozone generator 1, a first temperature control device 31, a water tank 2, and a second temperature control device 32. Among them, the ozone generator 1 is adapted to generate ozone. The first temperature control device 31 is connected to the ozone generator 1 and is adapted to cool or heat the water in the ozone generator 1 so that the TDS of the water in the ozone generator 1 reaches a preset TDS value. The water inlet of the water tank 2 is adapted to be connected to a water source. The air outlet of the ozone generator 1 is connected to the air inlet of the water tank 2. The second temperature control device 32 is connected to the water tank 2 and is adapted to cool or heat the water in the water tank 2 so that the solubility of ozone in the water reaches a preset solubility.

[0094] The control method mainly includes step S1, step S2, and step S3.

[0095] Among them, step S1 includes: controlling the first temperature control device 31 to operate at a preset first temperature so that the TDS of the water in the ozone generator 1 reaches a preset TDS value.

[0096] Step S2 includes: when the TDS of the water in the ozone generator 1 reaches a preset TDS value, controlling the ozone generator 1 to operate to generate ozone and introducing the ozone into the water tank 2.

[0097] Step S3 includes: controlling the second temperature control device 32 to operate at a preset second temperature so that the solubility of ozone in the water tank 2 reaches a preset solubility.

[0098] Therefore, the control method of Embodiment 2 can not only ensure that the water in the ozone generator 1 has a high conductivity and a high ozone generation efficiency, but also enable the generated ozone to be more fully dissolved in the water. Therefore, the solubility of ozone in the disinfected water prepared by the ozone generator 1 of Embodiment 2 is high, and the half-life of ozone is long, having a good disinfection and sterilization effect.

[0099] In this embodiment, before controlling the first temperature control device 31 to operate at a preset first temperature, it is preferably further included step S01.

[0100] Step S01 includes: obtaining the first gear information and determining the first temperature according to the first gear information.

[0101] Before controlling the second temperature control device 32 to operate at a preset second temperature, it is preferably further included step S02:

[0103] Among them, the first gear information preferably but not limited to includes low temperature gear, normal temperature gear and high temperature gear. The temperature range of the high temperature gear can be selected as [50°C, 60°C], the temperature range of the normal temperature gear can be selected as [20°C, 26°C], and the temperature range of the low temperature gear is [3°C, 7°C]. The second gear information preferably but not limited to includes warm gear, normal temperature gear and high temperature gear. The temperature range of the high temperature gear can be selected as [50°C, 60°C], the temperature range of the normal temperature gear can be selected as [20°C, 26°C], and the temperature range of the low temperature gear is [3°C, 7°C]. The first gear information and the second gear information can be set by the user. The initial settings of the first temperature control device 31 and the second temperature control device 32 are both room temperature. By setting the gear information of the first temperature control device 31 and the second temperature control device 32, a solution with a wider range of ozone solubility can be obtained, and the applicable range is wider. For example, in this embodiment, by setting the first temperature control device 31 and the second temperature control device 32, nine temperature control methods can be obtained, and disinfected water with various different concentrations can be obtained.

[0104] The nine temperature control methods are as follows: the first temperature control device 31 selects the high temperature gear and the second temperature control device 32 selects the high temperature gear; the first temperature control device 31 selects the high temperature gear and the second temperature control device 32 selects the normal temperature gear; the first temperature control device 31 selects the high temperature gear and the second temperature control device 32 selects the low temperature gear; the first temperature control device 31 selects the normal temperature gear and the second temperature control device 32 selects the high temperature gear; the first temperature control device 31 selects the normal temperature gear and the second temperature control device 32 selects the normal temperature gear; the first temperature control device 31 selects the normal temperature gear and the second temperature control device 32 selects the low temperature gear; the first temperature control device 31 selects the low temperature gear and the second temperature control device 32 selects the high temperature gear; the first temperature control device 31 selects the low temperature gear and the second temperature control device 32 selects the normal temperature gear; and the first temperature control device 31 selects the low temperature gear and the second temperature control device 32 selects the high temperature gear.

Before controlling the ozone generator 1 to generate ozone, it includes step S101, step S102, and step S103.

[0106] Step S101 includes: obtaining the TDS detection value of the first detection device 41;

[0107] Step S102 includes: judging whether the TDS detection value reaches a preset TDS value;

[0108] Step S103 includes: if the TDS detection value does not reach the preset TDS value, controlling the first temperature control device 31 to continue heating or cooling the water.

[0109] Therefore, when the water in the ozone generator 1 does not reach the preset TDS value, the first temperature control device 31 is controlled to heat or cool the water so that it reaches the preset TDS value, thereby increasing the conductivity of the water in the ozone generator 1 and improving the ozone generation efficiency of the ozone generator 1. Among them, the preset TDS value can be obtained from a preliminary experiment. For example, in this embodiment, the preset TDS value is in the range of 60 - 70 ppm, which can ensure that the water has a high conductivity. The preset solubility value can be set by the user.

[0118] Step S5 includes: judging whether the water level detection result is lower than a preset first water level;

[0119] Step S6 includes: if the water level detection result is lower than the preset first water level, control the water inlet pump 6 to make the water in the water source flow into the ozone generator 1. Therefore, the control module can timely control the water inlet pump 6 to supply water to the ozone generator 1 when the water level in the ozone generator 1 is low to ensure the smooth progress of the ozone generation operation.

[0120] In this embodiment, the control method preferably further includes step S7 and step S8.

Therefore, when the water level in the ozone generator 1 is too high, the excess water can be discharged into the water tank 2 and made into disinfected water, avoiding waste of water resources.

[0123] In this embodiment, the disinfected water generating device 100 further includes a first switching element 71. The first switching element 71 is arranged between the water outlet of the ozone generator 1 and the water inlet of the water tank 2. The control method further includes step S8 and step S9.

[0124] Among them, step S9 includes: when the water level detection result is higher than a preset second water level, controlling the first switching element 71 to connect the water outlet of the ozone generator 1 to the water inlet of the water tank 2;

[0125] Step S10 includes: when the water level detection result is equal to or lower than the preset second water level, controlling the first switching element 71 to cut off the connection between the water outlet of the ozone generator 1 and the water inlet of the water tank 2.

[0126] In this embodiment, the disinfected water generating device 100 further includes a fourth detection device and a second switching element 72.

[0132] In this embodiment, the control method preferably further includes step S14.

[0133] Step S14 includes: when the air pressure inside the ozone generator 1 is lower than the preset first air pressure, closing the second switching element 72.
