Description

Technical Field

[0001] The present application relates to the technical field of water treatment, and in particular to a bubble generating device and a household appliance. Background Art

[0002] In the related art, the generation of micro-nano bubble water almost always requires a device capable of pressurized solubilization, so that the air and water can be fully fused and then pass through the bubble generating device, so that the air dissolved in the water is fully released to form micro-nano bubble water. However, the solubilization device is often too large in size, which increases the cost of the product. At the same time, after a period of use, it is necessary to close the water inlet into the solubilization device and replenish air into the tank through the air replenishing device, which will cause discontinuous water output. The noise generated during air replenishment also makes the user experience poor. Due to the low water inlet pressure, the air and water in the capacity expansion tank cannot be fully dissolved, resulting in a weak output micro-nano bubble effect. Therefore, it is necessary to provide a bubble generating device to solve at least one of the above problems. Summary of the invention

Of course, they are only examples, and the purpose is not to limit the present application.

[0022] See also Figure 1 The bubble generating device 100 of the embodiment of the present application includes a detection module 10, a control module 20, and an electrolysis module 30. The detection module 10 is used to detect the influent flow rate and water quality and output a flow rate signal and a water quality signal. The control module 20 is used to generate a control signal according to the flow rate signal and the water quality signal. The electrolysis module 30 is used to electrolyze the influent according to the control signal to form micro-nano bubble water of a preset concentration.

[0023] The bubble generating device 100 of the embodiment of the present application can control the electrolysis module 30 to work through the control signal generated by the control module 20 to form micro-nano bubble water of a preset concentration, and the concentration can be adjusted. The electrolysis module 30 generates water by electrolysis in a more continuous and stable manner, and can continuously form micro-nano bubble water, and the micro-nano bubble effect is good.

[0024] The bubble generating device 100 of the embodiment of the present application can be applied to, but not limited to, household appliances such as water heaters, water dispensers, water purifiers, washing machines, and dishwashers.

[0025] Please refer again Figure 1 In some embodiments, the bubble generating device 100 may be connected to a water inlet pipe, which is used for water intake, and the detection module 10 may be disposed at the water inlet end of the water inlet pipe.

[0026] In some embodiments, the detection module 10 includes a first detection submodule, which is used to detect water flow and output a flow signal. The first detection submodule includes a water flow sensor, which is used to detect water flow and output a flow signal.

[0027] The water flow sensor includes a water flow rotor assembly, a control unit and a Hall element. The water flow sensor can be connected to the water inlet end of the water inlet pipe to measure the water flow rate and output a flow signal. When water flows through the rotor assembly of the water flow sensor, the magnetic rotor rotates, and the speed changes linearly with the flow rate. The Hall element outputs a corresponding pulse signal to feed back to the control unit, which determines the size of the water flow and outputs a flow signal.

[0028] In some embodiments, the detection module 10 includes a second detection submodule, which is used to detect water quality and output a water quality signal. The second detection submodule includes a TDS value detection sensor (Total dissolved solids, TDS). The TDS value detection sensor is used to detect water quality and output a water quality signal.

[0029] The TDS value detection sensor is a total dissolved solid detection sensor, and TDS is also called the total dissolved solids. The measurement unit is milligrams per liter (mg / L), and the TDS value indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved substances are contained in the water. The total dissolved solids refer to the total amount of all solutes in the water, including the content of both inorganic and organic substances. In some embodiments, the conductivity value can be used to roughly understand the salt content in the solution. Generally, the higher the conductivity, the higher the salt content, and the higher the TDS value. In inorganic substances, in addition to components dissolved in ions, there may also be inorganic substances in the form of molecules. Since the organic matter and the inorganic substances in the form of molecules contained in natural water can generally be ignored, the salt content is also referred to as total dissolved solids in some embodiments. The TDS value detection sensor can detect the total dissolved solids value (TDS value) in water, that is, to detect the total amount of various organic or inorganic substances dissolved in water, using units of ppm or milligrams per liter (mg / l). And it can measure conductive substances in water, such as suspended matter, heavy metals and conductive ions.

[0030] The water quality is related to the electrolysis efficiency of the electrolysis module 30. That is to say, when the electrolysis module 30 outputs the same current, the electrolysis efficiency varies with different water qualities. Therefore, the electrolysis module 30 can be controlled to output different currents at both ends according to the ion content (TDS value) in the water, thereby outputting micro-nano bubble water of different concentrations.

[0031] In one embodiment, the TDS value detection sensor can be used to detect water quality, and the water includes a variety of conductive ions, such as sulfate ions. The TDS value detection sensor can detect the amount of sulfate ions in the water to form a water quality signal. It is worth mentioning that the generation efficiency of micro-nano bubble water is related to the water quality. If the TDS value detection sensor detects that the sulfate ion content in the water is high, that is to say, the water itself has a strong conductivity, then the electrolysis module 30 can be controlled to reduce the current to ensure the electrolysis efficiency of the water.

[0032] In some embodiments, when the bubble generating device 100 is just started, the output current can be controlled to be relatively small to ensure the service life of the bubble generating device 100. When the bubble generating device 100 is just started, if the output current is controlled to be large, the electrolysis module 30 will be easily aged and damaged, thereby affecting the use of the bubble generating device 100.

[0033] In some embodiments, the control module 20 is electrically connected to the electrolysis module 30, and the control module 20 includes a processor, which can generate a control signal according to the flow signal and the water quality signal.

[0034] The processor can be a single-chip microcomputer chip that integrates a processor, memory, communication module, etc. The processor can refer to the processor contained in the controller. The processor can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0035] The micro-nano bubble water of preset concentration may refer to the micro-nano bubble water of a concentration customized by the user, or the micro-nano bubble water of a concentration set by the bubble generating device 100 before leaving the factory, which is not limited here.

[0036] In some embodiments, the bubble generating device 100 includes an input module, which includes at least one of a button, a knob switch, a microphone, and a touch screen. When using the bubble generating device 100, the user can set the concentration of micro-nano bubble water through the input module. Then, the flow signal and the water quality signal are obtained to generate a corresponding control signal, and the electrolysis module 30 generates current according to the control signal to form micro-nano bubble water of the set concentration.

[0037] In some embodiments, the bubble generating device 100 may include a communication component, and the communication component may communicate with the terminal by wire or wirelessly using Bluetooth, infrared, WIFI, mobile communication network, data line, etc. When the bubble generating device 100 is used, a preset concentration may be set by the terminal, the communication component receives the instruction sent by the terminal, and the bubble generating device 100 electrolyzes the incoming water according to the instruction to form micro-nano bubble water of a preset concentration. It is worth mentioning that the terminal includes but is not limited to mobile phones, tablet computers, wearable smart devices, personal computers, servers, and other household appliances.

[0038] The electrolysis module 30 generates water in a more continuous and stable manner, and can continuously generate micro-nano bubble water with good micro-nano bubble effect. At the same time, the bubble generating device 100 is simple and compact, which reduces production costs and does not occupy space.

[0039] In some embodiments, the control module 20 is used to control the electrolysis module 30 to start when the water flow rate represented by the flow signal is greater than a preset flow rate.

[0040] In some embodiments, the preset flow rate may be user-defined or may be set by the bubble generating device 100 before leaving the factory, which is not limited here.

[0041] In one embodiment, the preset flow rate includes 500 ml, 1 liter, 2 liters, 5 liters, 10 liters, etc., and the flow signal includes a flow signal. When the flow rate represented by the flow signal (i.e., the real-time water flow rate) is greater than the preset flow rate, the control module 20 can control the electrolysis module 30 to turn on. In one embodiment, the preset flow rate is 10 liters. When the real-time water flow rate is greater than 10 liters, the control module 20 controls the electrolysis module 30 to turn on. In this way, the effective output of the current of the electrolysis module 30 can be guaranteed, and energy loss can also be avoided.

[0042] In some embodiments, the control module 20 is used to control the electrolysis module 30 to start when receiving a micro-nano bubble water function start instruction and the water flow rate represented by the flow rate signal is greater than a preset flow rate.

[0043] In some embodiments, the bubble generating device 100 includes a micro-nano bubble water function and a conventional water function. When the conventional water function is used, the detection module 10, the control module 20, and the electrolysis module 30 are all in a closed state, and the water flow can flow into the cavity through the water inlet pipe, and the positive electrode and the negative electrode will not electrolyze the water in the cavity, and the water flow will flow to the water outlet pipe. When the bubble generating device 100 is in the micro-nano bubble water function, the detection module 10, the control module 20, and the electrolysis module 30 are all in a working state, and the water flow can flow into the cavity through the water inlet pipe, and the positive electrode and the negative electrode electrolyze the water in the cavity to generate micro-nano bubble water, and the micro-nano bubble water flows to the water outlet pipe.

[0044] In this way, the user can freely select the use mode of the bubble generating device 100 according to the needs, thereby improving the user's use experience. In the mode of the micro-nano bubble water function, an opening instruction can be generated, and the electrolysis module 30 can be controlled to be turned on or off according to whether the flow signal is greater than the preset flow. In this way, the effective output of the current of the electrolysis module 30 can be ensured, and energy loss can also be avoided.

[0045] In some embodiments, the electrolysis module 30 is used to adjust the working current according to the control signal and electrolyze the incoming water to form micro-nano bubble water of a preset concentration.

[0046] In one embodiment, if the user wants to obtain micro-nano bubble water of a preset concentration (i.e., the content of micro-nano bubbles in water is high), the control module 20 can generate a control signal to adjust the electrolysis module 30. Specifically, when the water inlet flow rate and water quality are the same, the user can increase the current to obtain a higher concentration of micro-nano bubble water, and the user can also reduce the current to obtain a low-high concentration of micro-nano bubble water. The control signal can be calculated through multiple information, such as: water inlet flow information, water quality information and preset concentration information, and the control amount is generated after calculation, and then the control signal is generated to control the electrolysis module 30 to electrolyze the water inlet, so that the preset concentration of micro-nano bubble water can be obtained. The bubble generating device 100 of the embodiment of the present application can control the electrolysis module 30 to work through the control signal generated by the control module 20 to form micro-nano bubble water of different concentrations, and the concentration can be arbitrarily adjusted within a certain range.

[0047] It is worth mentioning that the water flow sensor can obtain the water flow value, and the control module 20 can automatically turn on the electrolysis module 30 to electrolyze the incoming water when the water flow value is greater than the threshold. The bubble generating device 100 can also continuously detect the water flow value when electrolyzing the incoming water. When the water flow value is too large, the control module 20 can generate a control signal so that the electrolysis module 30 outputs a larger current to ensure the output of micro-nano bubble water of a preset concentration.

[0048] In some embodiments, the preset concentration is positively correlated with the operating current.

[0049] Specifically, the working current refers to the current when the electrolysis module 30 electrolyzes the incoming water. The larger the working current, the higher the concentration of the micro-nano bubble water. The smaller the working current, the lower the concentration of the micro-nano bubble water.

[0050] In this way, the working current can be adjusted to obtain micro-nano bubble water of different concentrations to meet the needs of users and enhance the user experience. The relationship between the preset concentration and the working current can be pre-calibrated and stored in the bubble generating device 100 or the household appliance.

[0051] In some embodiments, the electrolysis module 30 includes a cavity, a positive electrode and a negative electrode disposed in the cavity, and the positive electrode and the negative electrode are used to electrolyze water flowing through the cavity to form micro-nano bubble water of a preset concentration.

[0052] In some embodiments, the cavity includes a certain space so that it can store water and accommodate positive electrodes and negative electrodes. The cavity includes a water storage chamber with a water inlet and a water outlet. Water can flow into the cavity through the water inlet from the water inlet pipe for electrolysis, and then flow out through the water outlet after electrolysis. The cavity shape includes many types, and the cavity can be a cube, a sphere, a cylinder, an irregular body, etc., which are not limited here. The outside of the cavity can include insulating materials, so that the bubble generating device 100 is safer and more reliable when used.

[0053] In some embodiments, the positive electrode and the negative electrode can be arranged inside the cavity, and the two connection ends of the positive electrode and the negative electrode generally need to extend to the outside of the cavity to connect to electricity. In this way, the positive electrode and the negative electrode can be arranged on the corresponding sides of the cavity, and the positive electrode and the negative electrode can be fixed in the cavity.

[0054] Specifically, the positive electrode and the negative electrode will form a loop after being energized, so that water can be electrolyzed to produce micro-nano bubble water. Under the action of the positive electrode and the negative electrode, water can decompose hydrogen and oxygen. Hydrogen is difficult to dissolve in water, while oxygen is not easy to dissolve in water, but some oxygen will also dissolve in water. Some oxygen can exist in the form of microns (μm) or nanometers (nm) at the moment of dissolving in water.

[0055] Please refer again Figure 1 In some embodiments, the bubble generating device 100 further includes a water outlet component 40 , the water outlet component 40 has a Venturi structure, and the water outlet component 40 is connected to the water outlet end of the electrolysis module 30 .

[0056] Specifically, the water outlet component 40 may include a water outlet pipe, a water outlet valve, a water spray component, etc. The water outlet component 40 has a Venturi structure, that is, among the water outlet pipe, water outlet valve, water spray component, etc. included in the water outlet component 40, at least one element has a Venturi structure.

[0057] The Venturi structure refers to a structure that can produce the Venturi effect. The Venturi effect is manifested in that when the restricted flow passes through a reduced flow section, the fluid has an increased flow velocity, and its flow velocity is inversely proportional to the flow section. In some embodiments, the water outlet component 40 includes a Venturi tube, a bubbler with a Venturi structure, and the like. The Venturi structure can be understood as a conical structure. The cross-section of the Venturi tube changes from small to large, which can make the flow rate of the micro-nano bubble water change from slow to fast, so that the bubbles dissolved in the water can be quickly released, hydrogen is released, and part of the oxygen dissolved in the water is also released. When the water outlet component 40 with a Venturi structure is circulated, the bubbles in the nano form can be converted into bubbles in the micron form. The bubble water in the micron form is milky white in the sun and has better cleaning ability. In this way, the water outlet component 40 can enhance the micro-nano bubble effect.

[0058] Please refer again Figure 1 In some embodiments, the water outlet assembly 40 includes a water mixing valve 41, and the water mixing valve 41 has a first Venturi structure.

[0059] In one embodiment, the water outlet assembly 40 includes a water mixing valve 41 having a first venturi structure. The water mixing valve 41 having a first venturi structure can release a small amount of oxygen dissolved in the water and a small amount of air existing in the water into micro-nano bubbles, and can also control the water outlet flow rate of the micro-nano bubble water to ensure that the water outlet speed is constant and is not affected by changes in water temperature, flow rate, water pressure, etc.

[0060] In another embodiment, the water outlet assembly 40 includes a water mixing valve 41 having a first venturi structure. The water mixing valve 41 having a first venturi structure can release a small amount of oxygen dissolved in the water and a small amount of air in the water itself into micro-nano bubbles, and can also mix the micro-nano bubbles with other functional water to output functional water that meets the needs of users. For example: mix micro-nano bubble water at room temperature with heated conventional water to output water that meets the needs of users; mix micro-nano bubble water at room temperature with heated micro-nano bubble water to output water that meets the needs of users. In this way, more user needs can be met.

[0061] Please refer again Figure 1 In some embodiments, the water outlet assembly 40 includes a water outlet member 42 , the water outlet member 42 includes a second venturi structure, and the water inlet end of the water outlet member 42 is connected to the water outlet end of the mixing valve 41 .

[0062] In one embodiment, the water outlet 42 includes a shower head with a second venturi structure. The shower head with a second venturi structure can release a small amount of oxygen dissolved in the water and a small amount of air existing in the water into micro-nano bubbles, which is convenient for users to use. Users can use the shower head to shower, and the micro-nano bubble water can deeply cleanse the skin and remove grease.

[0063] Please refer again Figure 1 In some embodiments, the water mixing valve 41 may include multiple water outlets. In one embodiment, the water mixing valve 41 may include a first water outlet 411 and a second water outlet 412. The first water outlet 411 and the second water outlet 412 may be connected to multiple components for water outlet, such as a water outlet 42 and a faucet 43. The micro-nano bubble water may be discharged through any one or more components for water outlet. In this way, the practicality of the bubble generating device 100 can be enhanced to meet more user needs.

[0064] The bubble generating device 100 has a simple structure, can be modularly configured, does not occupy space, is convenient for users to use and install, and reduces production costs. It can also generate micro-nano bubble water of different concentrations, and is practical.

[0065] The household appliance according to the embodiment of the present application includes a bubble generating device 100 .

[0066] Household appliances include but are not limited to water heaters, water dispensers, washing machines, dishwashers and other household appliances.

[0067] Specifically, household appliances can generate micro-nano bubble water of preset concentrations. Micro-nano bubble water refers to water with tiny bubbles in the liquid. When the bubble diameter is below 100 microns (100 μm), it is called a micron bubble, and when the diameter is below 100 nanometers (100 nm), it is called a nano bubble. Micro-nano bubbles refer to bubbles with a diameter between tens of microns (μm) and hundreds of nanometers (nm) when bubbles occur. This type of bubble is between micron bubbles and nano bubbles, and has physical and chemical properties that conventional bubbles do not have.

[0068] Micro-nano bubbles have excellent oxygenation capacity, good flotation effect and strong oxidizing properties. They can be used to treat organic matter, nitrogen and phosphorus, and toxic and harmful substances in water, thereby effectively improving the water quality. When there are a large number of micro-nano bubbles in the water, the transparency of the water will be reduced. In the sun, the micro-nano bubble water is milky white. The bubbles in the micro-nano bubble water grow from zero to micron-sized bubbles and burst. The bass frequency generated has the effect of removing dirt. At the same time, the bass frequency can stimulate the production of endorphins, which makes people feel calm and happy.

[0069] The household appliance of the embodiment of the present application can control the electrolysis module 30 to work through the control signal generated by the control module 20 to form micro-nano bubble water of a preset concentration, and the concentration can be adjusted. The electrolysis module 30 generates water by electrolysis in a more continuous and stable manner, and can continuously form micro-nano bubble water, and the micro-nano bubble effect is good. At the same time, the bubble generating device 100 is simple and compact, which reduces production costs and does not take up space.
