The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.
Referring to fig. 1 to 6, the present invention provides a micro-nano bubble water generating device, which includes a gas mixing chamber 1, a gas inlet structure, a spraying structure 24 and a water pump 8. The gas mixing bin 1 is arranged on a water pipe 20 of the water heater and is communicated with the water pipe 20, and water in the water pipe 20 can flow into the gas mixing bin 1. One end of the air intake structure communicates with the water pipe 20, and can feed air into the water pipe 20. The spraying structure 24 is arranged at one end of the water pipe 20 communicated with the gas mixing bin 1, and water and gas in the water pipe 20 can be sprayed into the gas mixing bin 1 through the spraying structure 24. The water pump 8 is arranged on the water pipe 20 and used for adjusting the water pressure in the gas mixing bin 1, so that when the water and the gas in the water pipe 20 are sprayed into the gas mixing bin 1, the water pressure in the gas mixing bin 1 reaches a preset value P.
According to the invention, the spraying structure 24 is arranged at one end of the water pipe 20 communicated with the gas mixing bin 1, so that when water and gas in the water pipe 20 can be sprayed into the gas mixing bin 1, the water pressure is increased due to the effect of the spraying structure 24, the mixing capability of the water body and the gas is further enhanced, the gas is more easily dissolved in the water body, and the initial micro-bubble particle size with smaller size is obtained.
Alternatively, the air intake structure includes an intake pipe 4, an intake valve 6, and an air pump 5. One end of the air inlet pipe 4 is communicated with the water pipe 20, and the other end is communicated with the outside atmosphere of the air mixing bin 1. An intake valve 6 is provided in the intake pipe 4 for controlling the opening and closing of the intake pipe 4.

Optionally, the water heater further comprises a water outlet 3, the water outlet 3 is arranged on the gas mixing bin 1, and a water outlet pipe of the water heater is communicated with the gas mixing bin 1 through the water outlet 3.
Optionally, a first duct 21, a second duct 22 and a third duct 23 are also included. One end of the first pipe 21 communicates with the water pipe 20, and one end of the air intake pipe 4 communicates with the first pipe 21. One end of the second pipeline 22 is communicated with the first pipeline 21, and the inner diameter of the second pipeline 22 is gradually reduced from the end communicated with the first pipeline 21 to the end extending into the gas mixing bin 1. The third pipeline 23 is arranged in the gas mixing bin 1, one end of the third pipeline 23 is communicated with the other end of the second pipeline 22, the spraying structure 24 is arranged at the other end of the third pipeline 23, and the inner diameter of the third pipeline 23 is the same as the diameter of one end, extending into the gas mixing bin 1, of the second pipeline 22. Because the internal diameter of second pipeline 22 reduces from the one end with first pipeline 21 intercommunication to the one end that stretches into in the gas mixing storehouse 1 gradually, the internal diameter of third pipeline 23 is the same with the diameter that second pipeline 22 stretches into the one end in the gas mixing storehouse 1, and rivers can accelerate in water and the gas gets into second pipeline 22 from water pipe 20 through first pipeline 21 to reduce the diameter of bubble water.
Optionally, a third pipeline 23 is arranged at the upper part of the gas mixing bin 1, so that the spraying structure 24 sprays the water and the gas into the inside of the gas mixing bin 1.
Optionally, the spraying structure 24 includes a plurality of nozzles disposed at the other end of the third pipeline 23, and by disposing a plurality of nozzles, the spraying structure 24 can spray more gas and water into the gas mixing bin 1 at the same time, so as to improve the air intake and water intake of the gas mixing bin 1.

Optionally, a flow meter 9 is also included, the flow meter 9 being disposed on the water pipe 20 for detecting the flow of water into the water pipe 20 via a water supply pipe external to the water heater.
In another aspect, the present invention provides a control method for a water heater as described above, including the following steps:
s1: starting the water heater;
s2: judging whether a bubble water mode is selected, and if the bubble water mode is selected, entering S3;
s3: after water is boiled at the tail end of a water outlet pipe of the water heater, the pressure sensor 7 detects the current water pressure P in the gas mixing bin 1;
s4: judging whether the water pressure P is less than NMPa, and if the water pressure P is less than NMPa, starting the water pump 8 to enable the current water pressure P in the gas mixing bin 1 to reach NMPa; if the water pressure P is larger than or equal to NMPa, entering S5;
s5: detecting the water pressure P and the water flow V in the gas mixing bin 1 in real time, and operating the air pump 5 for a preset time T at corresponding power according to the current water pressure P and water flow V in the gas mixing bin 1;
s6: judging whether the water flow V is less than V1L/min or more than V2L/min, and if the water flow V is less than V1L/min or more than V2L/min, closing the air pump 5; if the water flow V is more than or equal to V2L/min and V1L/min is more than or equal to V2/min, the water in the gas mixing bin 1 flows out to the tail end of the water outlet pipe, and stable micro bubble water flow is generated through a special bubble water shower or a bubbler arranged at the tail end of the water outlet pipe.
According to the invention, by controlling the current water pressure P in the gas mixing bin 1, the current water pressure P in the gas mixing bin 1 can be greater than or equal to the preset value NMPa when the air pump 5 works, and further, the sufficient pressure in the gas mixing bin 1 is ensured to generate micro-nano bubble water. And when the water flow V is smaller than the minimum preset value V1, it indicates that the water pressure of the air mixing bin 1 is low and is not enough to generate micro-nano bubble water, and therefore, when the water flow V is smaller than the minimum preset value V1, the air pump 5 is directly turned off, that is, the bubble water function is turned off. When the water flow V is greater than the maximum preset value V2, it indicates that the water pressure in the air mixing bin 1 is too high, and when air is fed according to the preset gas-liquid ratio, the air inlet pressure also needs to be increased, and the too high air inlet pressure requirement will exceed the load of the air pump 5, so that the requirement cannot be met. In the bubble water program, it is required to continuously detect whether the water flow is smaller than the minimum preset value V1 or larger than the maximum preset value V2 at intervals of preset time to ensure the stability of bubble water generation.
Alternatively, in S2, if the bubble water mode is not selected, the method proceeds to the following steps:
s21: the air inlet pipe 4 is closed, and the air pump 5 is kept closed;
s22: entering a common bathing mode, and starting the water pump 8;
s23: switching to a bubble water mode;
s24: and judging whether the water flow V is more than or equal to V2L/min at the speed of V1L/min or not, and returning to S3 if the water flow V is more than or equal to V2L/min at the speed of V1L/min or not.
According to the invention, whether the water flow V is more than or equal to V2L/min at V1L/min or not is judged in the ordinary shower mode, and when the water flow V is more than or equal to V2L/min at V1L/min or not, the pressure value in the gas mixing bin 1 is in a preset range, bubble water can be generated, and then the operation returns to S3 to execute a bubble water program.
Alternatively, V1 is 2.5 and V2 is 15.
Optionally, S4 specifically is: judging whether the water pressure P is less than 0.3MPa, if so, starting the water pump 8 to enable the current water pressure P in the gas mixing bin 1 to reach 0.3 MPa; if the water pressure P is more than or equal to 0.3MPa, the process goes to S5.
Repeated experiments show that when the water pressure P is greater than or equal to 0.3MPa, bubble water can be generated in the gas mixing bin 1.
Optionally, the operation of the air pump 5 is controlled according to the gas-liquid ratio K so as to ensure the sufficient amount of bubbles in the bubble water.
Optionally, the gas-liquid ratio K is 5-10%, i.e. the gas pressure is greater than the water pressure, to ensure stable generation of bubble water. The gas-liquid ratio K in this embodiment is preferably 10%, for example, the current flow V is 10L/min, and the gas flow is 1L/min, and this flow can be adjusted by the periodic duty ratio PWM, for example, 20s is used as a unit when the gas pump 5 is started each time, and one unit is started at an interval of 10s, that is, the cycle is started twice every minute, and the cycle is started ten times when the gas pump is operated for five minutes.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
