Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a micro-nano bubble water device, a water heater and a household appliance. Background Art

[0002] Related technologies indicate that micro-nano bubble water refers to water containing a large number of tiny bubbles with diameters ranging from 0.1 to 50 μm. Micro-nano bubble water is currently widely used in industrial water treatment and water pollution treatment, and is now also being used in daily life and beauty products.

[0003] Due to their small size, micro-nano bubbles exhibit distinct properties from ordinary bubbles, such as long lifespan, high interfacial zeta potential, and high mass transfer efficiency. These properties can be exploited to create micro-nano bubble water for degrading agricultural residues in fruits and vegetables, killing bacteria and some viruses, and even partially removing antibiotics and hormones found in some meats.

[0045] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0046] Reference below Figures 1-4 The micro-nano bubble water device 100 according to an embodiment of the present invention includes: an air dissolving tank 1 , an air pump 52 and a micro-nano bubble generator 41 .

[0047] Specifically, a gas-liquid mixing chamber 16 is formed in the air dissolving tank 1, and a water inlet 12, a water outlet 13 and an air inlet 11 connected to the gas-liquid mixing chamber 16 are formed on the air dissolving tank 1. The water inlet 12 is connected to a water inlet pipe 7, and a water flow sensor 71 is provided on the water inlet pipe 7. The water flow sensor 71 is used to detect the water flow in the water inlet pipe 7. The water outlet 13 is connected to the water outlet pipe 6, and the air inlet 11 is connected to the air inlet pipe 5. An air pump 52 is connected to one end of the air inlet pipe 5 for filling air into the air dissolving tank 1, and the air pressure pumped by the air pump 52 is not less than the water inlet pressure of the water inlet 12.

[0048] That is, the gas-liquid mixing chamber 16 is formed in the air dissolving tank 1, the water inlet 12, the water outlet 13, and the air inlet 11 are formed on the air dissolving tank 1, and the water inlet 12, the water outlet 13, and the air inlet 11 are all connected to the gas-liquid mixing chamber 16. The water inlet pipe 7 is connected to the water inlet 12, the water outlet pipe 6 is connected to the water outlet 13, the air inlet pipe 5 is connected to the air inlet 11, and the air pump 52 is connected to the air inlet pipe 5. The air pump 52 is used to pump air into the air dissolving tank 1. The air pressure pumped by the air pump 52 is greater than or equal to the water inlet pressure of the water inlet 12. As a result, the overall device has a simple structure, simplified component structure, small size, and light weight.

[0049] like Figure 1 As shown, a gas-liquid mixing chamber 16 is formed in the air dissolving tank 1, and a water inlet 12, a water outlet 13 and an air inlet 11 are formed on the air dissolving tank 1. The gas-liquid mixing chamber 16 in the air dissolving tank 1 is communicated with the water inlet 12, the water outlet 13 and the air inlet 11. The water inlet pipe 7 is connected to the water inlet 12, the water outlet pipe 6 is connected to the water outlet 13, the air inlet pipe 5 is connected to the air inlet 11, and the right end of the air inlet pipe 5 is connected to an air pump 52, which is used to pump air into the gas-liquid mixing chamber 16 of the air dissolving tank 1.

[0050] When the micro-nano bubble water device 100 is in use, water enters the gas-liquid mixing chamber 16 of the air dissolving tank 1 through the water inlet 12, and the air is converted into high-pressure air after passing through the air pump 52. The air enters the gas-liquid mixing chamber 16 of the air dissolving tank 1 through the air inlet 11. The water and air are fully mixed in the gas-liquid mixing chamber 16 of the air dissolving tank 1, and finally flow out from the water outlet 13 for use by the user.

[0051] According to the micro-nano bubble water device 100 of the embodiment of the present invention, by providing an air pump 52 at one end of the water inlet pipe 7, the air entering the gas-liquid mixing chamber 16 is high-pressure air, and the water inlet pipe 7 is a normally open water path, thereby improving the quality and production efficiency of the micro-nano bubble water. The overall structure of the micro-nano bubble water device 100 is simple, which simplifies the use of components, reduces production costs, improves product cost-effectiveness, and optimizes the user experience.

[0052] In some embodiments of the present invention, the micro-nano bubble water device 100 further includes a controller 3 , which is communicatively connected to the air pump 52 and controls the start and stop of the air pump 52. In other words, the controller 3 controls the start and stop of the air pump 52. As a result, the micro-nano bubble water device 100 has a simple structure and is easy to use.

[0053] In some embodiments of the present invention, the micro-nano bubble water device 100 further includes a pressure-stabilizing valve 72, which is provided on the water inlet pipe 7 to stabilize the water inlet pressure. When the tap water pressure is unstable, the pressure-stabilizing valve 72 can stabilize the tap water pressure at a predetermined value, thereby ensuring stable water pressure within the micro-nano bubble water device 100 and improving the safety and reliability of the micro-nano bubble water device 100.

[0054] In some embodiments of the present invention, a water flow sensor 71 is provided on the water inlet pipe 7 for detecting the water flow within the water inlet pipe 7. The water flow sensor 71 is communicatively connected to the controller 3. In other words, to detect the water flow within the water inlet pipe 7, the water flow sensor 71 is provided on the water inlet pipe 7 and is communicatively connected to the controller 3. This allows for accurate control of the water flow rate within the gas-liquid mixing chamber 16, ensuring the quality of the micro-nano bubble water and conserving resources.

[0055] In some embodiments of the present invention, the controller 3 is configured to activate the air pump 52 when the water flow sensor 71 detects a water flow signal. In other words, the controller 3 activates the air pump 52 when the water flow sensor 71 detects a water flow signal. This results in a simple structure and ease of use for the micro-nano bubble water device 100.

[0056] In some embodiments of the present invention, a liquid level sensor is provided within the gas dissolving tank 1 for detecting the water level within the gas dissolving tank 1. The liquid level sensor is communicatively connected to the controller 3. In other words, to detect the water level within the gas dissolving tank 1, a liquid level sensor is provided within the gas dissolving tank 1, and the controller 3 is communicatively connected to the liquid level sensor. This allows accurate measurement of the water level within the gas dissolving tank 1, further ensuring the bubble density of the micro-nano bubble water and improving the preparation efficiency of the micro-nano bubble water.

[0057] In some embodiments of the present invention, the controller 3 is configured to activate the air pump 52 to inject high-pressure air into the air dissolving tank 1 when the water level in the air dissolving tank 1 exceeds a predetermined set point. In other words, when the water level in the air dissolving tank 1 exceeds the predetermined set point, the controller 3 controls the air pump 52 to activate, pumping high-pressure air into the air dissolving tank 1. As a result, the micro-nano bubble water device 100 has a simple structure and a modular design, which reduces production costs and installation space.

[0058] In some embodiments of the present invention, the air pressure pumped by the air pump 52 is within a range of 0.1 MPa to 1.2 MPa; and / or the water pressure of the water inlet pipe 7 is within a range of 0.01 MPa to 1.2 MPa. In other words, the air pressure pumped by the air pump 52 may be within a range of 0.1 MPa to 1.2 MPa; the water pressure of the water inlet pipe 7 may be within a range of 0.01 MPa to 1.2 MPa; or the air pressure pumped by the air pump 52 may be within a range of 0.1 MPa to 1.2 MPa, and the water pressure of the water inlet pipe 7 may be within a range of 0.01 MPa to 1.2 MPa. This simplifies the control logic of the controller 3 and reduces production costs.

[0059] For example, the air pressure pumped by the air pump 52 can be: 0.1MPa, 0.15MPa, 0.2MPa, 0.25MPa, 0.3MPa, 0.35MPa, 0.4MPa, 0.45MPa, 0.5MPa, 0.55MPa, 0.6MPa, 0.65MPa, 0.7MPa, 0.75MPa, 0.8MPa, 0.85MPa, 0.9MPa, 0.95MPa, 1.0MPa, 1.05MPa, 1.1MPa, 1.15MPa, 1.2MPa and the like.

[0060] The water inlet pressure of the water inlet pipe 7 can be: 0.01MPa, 0.05MPa, 0.1MPa, 0.15MPa, 0.2MPa, 0.25MPa, 0.3MPa, 0.35MPa, 0.4MPa, 0.45MPa, 0.5MPa, 0.55MPa, 0.6MPa, 0.65MPa, 0.7MPa, 0.75MPa, 0.8MPa, 0.85MPa, 0.9MPa, 0.95MPa, 1.0MPa, 1.05MPa, 1.1MPa, 1.15MPa, 1.2MPa and the like.

[0061] In some embodiments, after the user opens the water outlet valve 61, the water flows through the water flow sensor 71 and sends a water flow signal to the controller 3. When the liquid level sensor in the air dissolving tank 1 detects that the water level in the gas-liquid mixing chamber 16 is higher than the predetermined setting position, a signal is sent to the controller 3. The controller 3 controls the air pump 52 to start, and the air pump 52 pumps air with a pressure in the range of 0.1MPa to 1.2MPa into the gas-liquid mixing chamber 16. Under the action of water pressure, the water flow mixes with the air, and the air dissolves in the water. After the air in the gas-liquid mixing chamber 16 gradually dissolves in the water, the air gradually decreases, and the air pump 52 performs continuous or intermittent inflation to replenish the air in the air dissolving tank 1 so as to continuously generate micro-nano bubble water.

[0062] In some embodiments of the present invention, a jet element for ejecting fluid into the air dissolving tank 1 is provided at the water inlet 12, and / or a plurality of water inlet holes arranged at intervals are provided at the water inlet 12. In other words, a jet element can be provided at the water inlet 12 of the air dissolving tank 1 to eject fluid into the gas-liquid mixing chamber 16, a plurality of water inlet holes arranged at intervals can be provided at the water inlet 12, or both a jet element and a plurality of water inlet holes can be provided at the water inlet 12. In this way, when water flows into the air dissolving tank 1, the water flow rate increases, thereby improving the contact between water and air, making the air bubbles in the mixed flow of air bubbles in the air dissolving tank 1 more dense, thereby improving the quality of the micro-nano bubble water.

[0063] In some embodiments of the present invention, the water outlet 13 is formed at the bottom of the air dissolving tank 1, the water inlet 12 is formed at the top or upper portion of the air dissolving tank 1, and the air inlet 11 is formed at the top, bottom, or side wall of the air dissolving tank 1. In other words, the air inlet 11 can be formed at the top of the air dissolving tank 1, the air inlet 11 can also be formed at the bottom of the air dissolving tank 1, the air inlet 11 can also be formed at the side wall of the air dissolving tank 1, the water inlet 12 can be formed at the top of the air dissolving tank 1, the water inlet 12 can also be formed at the upper portion of the air dissolving tank 1, and the water outlet 13 is formed at the bottom of the air dissolving tank 1. In this way, different usage scenarios can be met according to different user needs, which is flexible and convenient.

[0064] like Figure 3 As shown, the water inlet 12 is formed at the top of the air dissolving tank 1, which can increase the water flow rate and increase the air bubble content of the air bubble mixed flow; the air inlet 11 is formed at the top of the air dissolving tank 1, which has a simple structure and is easy to assemble; the water outlet 13 is formed at the bottom of the air dissolving tank 1, and utilizes the gravity of the water itself and the pressure in the air dissolving tank 1. The water flow can flow out smoothly without the need to set up additional parts, and there is no long-term stagnant water, which affects the water quality and harms human health.

[0065] In some embodiments of the present invention, the micro-nano bubble water device 100 further includes a micro-nano bubble generator 41 , which is connected to the water outlet pipe 6 and is used to convert dissolved air water into micro-nano bubble water.

[0066] In some embodiments, the micro-nano bubble generator 41 may include a micro-nano bubble generator with an axially through-going micro-nano bubble water microchannel. The micro-nano bubble water microchannel may be a Venturi tube structure. One or more micro-nano bubble water microchannels may be provided. The dissolved air in the bubble water channel is discharged through the micro-nano bubble water microchannel, thereby generating micro-nano bubble water with a high micro-nano bubble density.

[0067] In some embodiments of the present invention, the micro-nano bubble water device 100 further includes a water outlet 4 connected to the end of the water outlet pipe 6 facing away from the water outlet 13, and a micro-nano bubble generator 41 disposed within the water outlet 4. The water outlet 4 can be a shower or a faucet. In other words, the water outlet 4 can be a shower or a faucet, connected to the water outlet pipe 6 at the end facing away from the water outlet 13, with the micro-nano bubble generator 41 located within the water outlet 4. This reduces the dissipation of micro-nano bubbles in the water outlet pipe 6, further improving the quality of the micro-nano bubble water, and facilitating installation and maintenance.

[0068] In some embodiments of the present invention, a one-way valve 51 is connected in series to the air inlet pipe 5, and / or a water outlet valve 61 is connected in series to the water outlet pipe 6. The water outlet valve 61 is located upstream of the micro-nano bubble generator 41 in the direction of water flow. In other words, the one-way valve 51 can be connected in series only to the air inlet pipe 5, the water outlet valve 61 can be connected in series only to the water outlet pipe 6, or both the one-way valve 51 and the water outlet pipe 6 can be connected in series, with the micro-nano bubble generator 41 located downstream of the water outlet valve 61 in the direction of water flow. As a result, the micro-nano bubble water device 100 has a simple structure, an ingenious design, and is easy to use.

[0069] Further, if Figure 3 As shown, a water pump 73 is also connected in series to the water inlet pipe 7 to increase the water inlet pressure, thereby improving the preparation effect of micro-nano bubble water.

[0070] The following will refer to Figures 1-4 The micro-nano bubble water device 100 according to two specific embodiments of the present invention is described.

[0071] Example 1, as Figure 1 As shown, the micro-nano bubble water device 100 includes: an air dissolving tank 1, an air pump 52, a micro-nano bubble generator 41, a controller 3, a power supply device 2, a water outlet valve 61, a one-way valve 51 and a water outlet component 4.

[0072] Reference Figure 1As shown, a gas-liquid mixing chamber 16 is formed in the air dissolving tank 1, a liquid level sensor is provided in the air dissolving tank 1, and the controller 3 is communicatively connected to the liquid level sensor. An air inlet 11, a water inlet 12 and a water outlet 13 are formed on the air dissolving tank 1. The water outlet 13 is formed at the bottom of the air dissolving tank 1, the water outlet 13 is connected to the water outlet pipe 6, the outlet valve 61 is connected in series to the water outlet pipe 6, the water inlet 12 is formed at the top of the air dissolving tank 1, the water inlet pipe 7 is connected to the water inlet 12, a water flow sensor 71 is provided in the water inlet pipe 7, the controller 3 is communicatively connected to the water flow sensor 71, the air inlet 11 is formed at the top of the air dissolving tank 1, the air inlet pipe 5 is connected to the air inlet 11, the air pump 52 is connected to the right end of the air inlet pipe 5, the controller 3 is communicatively connected to the air pump 52, the one-way valve 51 is connected in series to the air inlet pipe 5, the micro-nano bubble generator 41 is located in the water outlet part 4, and the power supply device 2 is connected to the controller 3.

[0073] Specifically, the dissolved air tank 1 includes: a shell 14 and a partition 15. The shell 14 includes: a first end cover 141, a second end cover 142 and a main cavity. The partition 15 is located inside the main cavity. A through hole 151, a connecting flange and a water trough are formed on the partition 15. The connecting flange is welded to the inner peripheral wall of the main cavity. The partition 15 separates the main cavity into a mixing chamber and a dissolved water chamber. The mixing chamber is located on the left side of the partition 15, and the dissolved water chamber is located on the right side of the partition 15. The water inlet 12 is formed just above the mixing chamber, the water outlet 13 is formed at the bottom of the shell 14, and the water outlet 13 is formed below the dissolved water chamber. The air inlet 11 is formed at the top of the shell 14. The main cavity is formed with an avoidance recess facing the inside of the main cavity at the water outlet 13, the air inlet 11 and the water inlet 12. The overall structure of the dissolved air tank 1 is simple, easy to install and maintain, and has low production cost.

[0074] When the water inlet pressure is less than the air inlet pressure, the air dissolving tank 1 is first closed with the water inlet 12. High-pressure air enters the housing 14 of the air dissolving tank 1 through the air inlet 11. The water in the air dissolving tank 1 is injected into the air dissolving tank 1 from the water outlet 13 through the multiple water inlet holes. The air enters the air dissolving tank 1. After the air dissolving tank 1 is partially or completely filled with air, the compressed air supply is stopped. Then, the water inlet 12 is opened, and high-pressure water enters the gas-liquid mixing chamber 16 of the air dissolving tank 1 through the water inlet 12. In the high-pressure gas-liquid mixing chamber 16, the water flow impacts to form air bubble mixed flow, which increases the contact area between air and water and increases the content of air dissolved in water, eventually forming dissolved water. The dissolved water flows into the dissolved water chamber through the partition 15.

[0075] Alternatively, the micro-nano bubble generator 41 may include a micro-nano bubbler with an axially through-going micro-nano bubble water micro-channel, the micro-nano bubble water micro-channel may be a venturi tube structure, one or more micro-nano bubble water micro-channels may be provided, and the dissolved air in the bubble water channel is discharged through the micro-nano bubble water micro-channel, thereby producing micro-nano bubble water with a high micro-nano bubble density. Since the water hole size of the micro-nano bubble water micro-channel of the micro-nano bubble generator 41 is small, especially when the water pressure of the inlet water is low, the water output is even smaller, which makes it difficult to meet the normal water needs of the user. Therefore, in addition to being provided with the micro-nano bubble water micro-channel, the micro-nano bubble generator 41 may also be provided with a gap water flow channel. When the water pressure of the inlet water is low, the gap water flow channel can be opened to increase the water output of the micro-nano bubble generator 41. When the water pressure of the inlet water is high, the gap water flow channel can be cut off to discharge the micro-nano bubble water from the micro-nano bubble water micro-channel of the micro-nano bubble generator 41.

[0076] When using the micro-nano bubble water device 100, after the user opens the water outlet valve 61, water flows through the water flow sensor 71, generating a water flow signal that is transmitted to the controller 3. When the liquid level sensor in the air dissolving tank 1 detects that the water level in the gas-liquid mixing chamber 16 is above a predetermined set point, a signal is transmitted to the controller 3, which controls the air pump 52 to start. The air pump 52 pumps air at a pressure within the gas-liquid mixing chamber 16 within a range of 0.1 MPa to 1.2 MPa. Under the action of the water pressure, the water and air mix, and the air dissolves in the water. After the air in the gas-liquid mixing chamber 16 gradually dissolves in the water, the air gradually decreases, and the air pump 52 continuously or intermittently inflates the air to replenish the air in the air dissolving tank 1, thereby continuously producing micro-nano bubble water. When the micro-nano bubble water flows out of the water outlet 4, it passes through the micro-nano bubble generator 41 within the water outlet 4, thereby producing micro-nano bubble water.

[0077] Example 2, as Figure 3 As shown, in the second embodiment, the micro-nano bubble water device 100 further includes: a pressure-stabilizing valve 72 and a water pump 73. The structure of this embodiment is roughly the same as that of the first embodiment, wherein the same components are marked with the same reference numerals. The only difference is that: in the second embodiment, the water inlet pressure is not less than the air inlet pressure. In order to stabilize the water inlet pressure to be less than the air inlet pressure, a pressure-stabilizing valve 72 and a water pump 73 are provided on the water inlet pipe 7, which can control the water inlet pressure to be less than the air inlet pressure.

[0079] It should be noted that the first embodiment is applicable to the case where the water inlet pressure is less than the air inlet pressure, while the second embodiment is applicable to the case where the water inlet pressure is not less than the air inlet pressure.

[0080] The water heater 1000 according to the second embodiment of the present invention includes a heating device 400 and the micro-nano bubble water device 100 according to the first embodiment of the present invention.

[0081] The water heater 1000 according to the embodiment of the present invention is provided with the micro-nano bubble water device 100 according to the first embodiment, thereby improving the practicality and safety of the water heater 1000.

[0082] Optionally, the heating device 400 is an overflow heater, and the micro-nano bubble water device 100 is connected downstream of the heating device 400 in the water flow direction.

[0083] In some embodiments, the micro-nano bubble generator 41 is connected to the water outlet of the water heater 1000 to generate micro-nano bubble water.

[0084] The following will refer to Figures 1-4 A water heater 1000 according to a specific embodiment of the second aspect of the present invention is described.

[0085] Reference Figure 3 As shown, the water heater 1000 includes: a cold water inlet flow channel 200 , a hot water outlet flow channel 300 , a heating device 400 and a micro-nano bubble water device 100 .

[0086] Specifically, the cold water inlet flow channel 200 is connected to the heating device 400, the upper end of the hot water outlet flow channel 300 is connected to the heating device 400, and the lower end of the hot water outlet flow channel 300 is connected to the dissolved air tank 1. A gas-liquid mixing chamber 16 is formed in the dissolved air tank 1, and a liquid level sensor is provided in the dissolved air tank 1. The controller 3 is communicatively connected to the liquid level sensor. An air inlet 11, a water inlet 12 and a water outlet 13 are formed on the dissolved air tank 1. The water outlet 13 is formed at the bottom of the dissolved air tank 1, the water outlet 13 is connected to the water outlet pipe 6, and the outlet valve 61 is connected in series to the outlet. On the water pipe 6, a water inlet 12 is formed at the top of the air dissolving tank 1, the water inlet pipe 7 is connected to the water inlet 12, a water flow sensor 71 is arranged in the water inlet pipe 7, the controller 3 is communicated with the water flow sensor 71, the hot water outlet channel 300 is connected to the water inlet pipe 7, the air inlet 11 is formed at the top of the air dissolving tank 1, the air inlet pipe 5 is connected to the air inlet 11, the air pump 52 is connected to the right end of the air inlet pipe 5, the controller 3 is communicated with the air pump 52, the one-way valve 51 is connected in series to the air inlet pipe 5, and the micro-nano bubble generator 41 is located in the water outlet part 4.

[0087] When the gas water heater is in use and the water inlet pressure is lower than the air inlet pressure, cold water flows from the cold water inlet channel 200 into the heating device 400 of the gas water heater. The cold water is converted into hot water in the heating device 400. The hot water then flows from the hot water outlet channel 300 through the water inlet pipe 7 of the micro-nano bubble water device 100 into the gas-liquid mixing chamber 16 of the air dissolving tank 1. Simultaneously, the water flow sensor 71 transmits a water flow signal to the controller 3. When the liquid level sensor in the air dissolving tank 1 detects that the water level in the gas-liquid mixing chamber 16 is above a predetermined level, it transmits a signal to the controller 3, which activates the air pump 52, which pumps high-pressure air into the gas-liquid mixing chamber 16. The water mixes with the high-pressure air, dissolving the air in the water. The air in the air dissolving tank 1 gradually decreases, and the air pump 52 continuously or intermittently pumps air into the air dissolving tank 1 to maintain the air pressure within a certain range. This ensures the quality of the micro-nano bubble water and improves the user experience.

[0088] When the water inlet pressure is not less than the air inlet pressure, Figure 3 As shown, when cold water flows from the cold water inlet channel 200 into the heating device 400 of the gas water heater, the pressure regulating valve 72 and the water pump 73 are opened. The pressure regulating valve 72 stabilizes the water inlet pressure, and the water pump 73 is used to increase the water pressure and improve the gas dissolution rate. This further ensures the bubble content of the micro-nano bubble water and improves the efficiency of micro-nano bubble water production.

[0089] Further, refer to Figure 3 As shown, a water pump 73 is connected in series to the water inlet pipe 7, which can be used to start the circulation preheating function of the water heater 1000.
