For example, as shown in fig. 12, the bubble water outlet 114 is formed at the bottom of the dissolved air tank 110, and during the operation of the electric water heater 100, a certain amount of micro-nano bubble water is always in the dissolved air tank 110, and the pressure of the bottom of the dissolved air tank 110 is the maximum, so that the micro-nano bubble water discharged from the bubble water outlet 114 has the maximum pressure, and thus, in the discharged micro-nano bubble water, a good spraying state can be ensured, and the use requirement of a user can be met.

In some embodiments of the present invention, as shown in fig. 9, a check valve 180 is connected in series between the air pump 120 and the air inlet 112, where the check valve 180 is used to control the air pumped from the air pump 120 to flow only from the air pump 120 to the air inlet 112, but not to flow back from the air inlet 112 to the air pump 120, so that the air can be prevented from flowing back, and thus the air pumped from the air pump 120 can enter the dissolved air tank 110 each time, so that sufficient air and water are mixed in the dissolved air tank 110, and the formation of high-quality micro-nano bubble water is ensured.

For example, as shown in fig. 9, the air pump 120 is connected to the upstream of the check valve 180, the air inlet 112 is connected to the downstream of the check valve 180, when the air pump 120 needs to work, the air pumped by the air pump 120 flows through the check valve 180 to enter the air inlet 112, enters the dissolved air tank 110 through the air inlet 112 to be mixed with the water in the dissolved air tank 110, when the air pump 120 stops working, the air flows back, and then flows to the check valve 180 through the air inlet 112, the air cannot pass through the check valve 180, so that the air pumped by the air pump 120 can be completely used for generating micro-nano bubble water, and the quality and the generation efficiency of the micro-nano bubble water are improved.

As shown in fig. 9, an air inlet pipe 121 is connected between the air pump 120 and the air inlet 112, a bending joint is connected in series on the air inlet pipe 121, the bending joint can determine its own specific position according to the specific position of the air pump 120, so that the adaptability to the installation space when the air pump 120 is installed is improved, and meanwhile, the pressure of passing gas can be increased when the bending joint is opposite to the straight joint, which is beneficial to the full fusion of the gas and water in the dissolved air tank 110, so as to form high-quality micro-nano bubble water.

In some embodiments of the present invention, as shown in fig. 5, the electric rapid heating water heater 100 may further include a solenoid valve 190, wherein the solenoid valve 190 is connected in series between the inlet of the water pump 130 and the water inlet pipe 131, and the solenoid valve 190 is used to control the switch of the booster water pump 130.

Specifically, the electromagnetic valve 190 is a normally open electromagnetic valve 190, the booster water pump 130 is controlled to be opened to boost the pressure of the water introduced into the dissolved air tank 110, after the electromagnetic valve 190 is electrified, the electromagnetic valve 190 is closed, the booster water pump 130 stops working, and only the water is continuously introduced into the dissolved air tank 110.

For example, as shown in fig. 1, an air inlet 112 is formed at the top of the dissolved air tank 110, an air inlet 113 is formed at the upper portion of the dissolved air tank 110, the air inlet 112 is vertically opposite to the air inlet 113, and a bubble water outlet 114 is formed at the lower portion of the dissolved air tank 110, so that the air inlet 112 and the air inlet 113 supply air and water to the dissolved air tank 110, respectively, form micro-nano bubble water in the dissolved air tank 110, and then flow out of the dissolved air tank 110 through the bubble water outlet 114.

It should be noted that, this control process is implemented when the electric water heater 100 is started each time, specifically, as shown in fig. 18, when the flow sensor 1431 located at the outlet end of the heat exchange tube 141 detects a water flow signal, the signal is transmitted to the power board 160, the power board 160 transmits a signal for opening the solenoid valve 190 to the solenoid valve 190, after the water enters the dissolved air tank 110 through the water inlet 113 for a first preset time, the power board 160 transmits a signal for closing the solenoid valve 190 to the solenoid valve 190, so that the water pump 130 stops supplying water to the dissolved air tank 110 for a second preset time, meanwhile, the power board 160 transmits an open signal to the air pump 120, the air pump 120 pumps air from the air inlet into the dissolved air tank 110, and likewise for a second preset time, after the second preset time, the power board 160 transmits an open signal to the solenoid valve 190, the solenoid valve 190 is opened to continuously supply water to the dissolved air tank 110, and the power board 160 transmits a closed signal to the air pump 120, and the air pump 120 is closed, and air is stopped from being pumped into the dissolved air tank 110.

It should be noted that, when the electric water heater 100 is restarted each time, there is a part of the liquid remaining in the solution tank 110, at this time, if water is continuously introduced directly and air is periodically pumped in, the fusion of the gas and water in the micro-nano bubble water discharged at the beginning is insufficient, so that the water in the solution tank 110 and the introduced gas are fully fused by performing the water-break air-supplementing once at the beginning, and the stable micro-nano bubble water is ensured to be generated.

The water pump 130 is further provided with a silicon controlled rectifier 132, wherein the silicon controlled rectifier 132 is a high-power electrical component, which is also called a thyristor. It has the advantages of small volume, high efficiency, long service life, etc. In an automatic control system, the device can be used as a high-power driving device to control high-power equipment by using a low-power control.

According to the control method of the rapid heating electric water heater 100 of the invention, water in the dissolved air tank 110 and the introduced gas are fully fused each time the rapid heating electric water heater 100 is started, and stable micro-nano bubble water is generated.

In some embodiments of the present invention, as shown in fig. 18, the first preset time is 50s-90s, and in a specific implementation, the first preset time may be set to 50s, 55s, 60s, 65s, 70s, 75s, 80s, 85s and 90s, and the second preset time is 1s-5s, and in a specific implementation, the second preset time may be set to 1s, 1.5s, 2s, 2.5s, 3s, 3.5s, 4s, 4.5s and 5s, according to the actual situation.

For example, in a specific implementation process, the first preset time may be set to 60s, and the second preset time may be set to 1.5s, so that the ratio of water to gas in the dissolved air tank 110 may be ensured to meet the requirements, which is more favorable for forming fine and smooth micro-nano bubble water.

In some embodiments of the present invention, referring to fig. 1, the water pump 130 of the rapid heating electric water heater 100 is a booster water pump 130, so that the water pressure of the water entering the dissolved air tank 110 can be increased, which is beneficial to mixing with the gas in the dissolved air tank 110 to form micro-nano bubble water, when a water flow signal is detected at the outlet end of the heat exchange tube 141, the electromagnetic valve 190 is opened, and the air pump 120 is closed, the booster water pump 130 is opened.

In some embodiments of the present invention, as shown in fig. 18, the control method may further include: s4, judging whether the dissolved air tank 110 meets the preset air supplementing condition, when the preset air supplementing condition is met, opening the air pump 120, and when the air pressure in the dissolved air tank 110 reaches the preset pressure or the air supplementing of the air pump 120 reaches the preset time, closing the air pump 120, so that proper amount of air and water can be ensured to be always in the dissolved air tank 110, and the micro-nano bubble water can be continuously formed by the quick-heating electric water heater 100.

For example, in the use process of the rapid thermal electric water heater 100, a pressure sensor is arranged in the air dissolving tank 110, when the air pressure in the air dissolving tank 110 is lower than a preset pressure value, the pressure sensor transmits a signal to the power supply board 160, the power supply board 160 transmits a signal for opening the air pump 120 to the air pump 120, the air pump 120 is opened to inflate the air dissolving tank 110, when the air pressure in the air dissolving tank 110 reaches the preset pressure value, the pressure sensor transmits a signal to the power supply board 160, the power supply board 160 transmits a signal for closing the air pump 120 to the air pump 120, the air pump 120 is closed, and the air pump 120 stops inflating into the air dissolving tank 110, and in this way, circulation is performed to ensure that the rapid thermal electric water heater 100 can stably generate high-quality micro-nano bubble water.

For example, the air pump 120 is set for a predetermined time each time of air supplement, and the time interval between every two adjacent air supplements is also set for a predetermined time, so, in the practical process of the rapid thermal electric water heater 100, when the dissolved air tank 110 is filled with water for a certain time, the power panel 160 transmits an open signal to the air pump 120, the air pump 120 is opened to inflate the dissolved air tank 110, after the air pump 120 is inflated for a predetermined time, the air pump 120 is automatically closed, the dissolved air tank 110 is directly filled with water in the whole circulation process, and the rapid thermal electric water heater 100 can stably generate high-quality micro-nano bubble water by circulating in this way.

In some embodiments of the present invention, the control method may further include: the heater 140 is turned off at a third preset time before the air pump 120 is turned on; when the air pump 120 is turned on, the heater 140 is turned on again, and it is noted that the higher the gas content in the micro-nano bubble water, the less heat is required to heat to the same temperature, and in the process of inflating the air pump 120 with the dissolved air tank 110, the air pump 120 is turned on, so that the content of the gas in the micro-nano bubble water is rapidly increased, the heat is reduced, and the heater 140 is turned off for a third preset time before the air pump 120 is turned on, so that the stable and fine micro-nano bubble water can be generated by the quick-heating electric water heater 100, and meanwhile, the energy is saved.

In some embodiments of the present invention, the third preset time is 2s-10s, that is, in a specific implementation, the third preset time may be set to 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, and 10s.
