Description

Technical Field

[0001] This application relates to the technical field of gas water heaters, and particularly to a double-tank constant-temperature bubble water device. Background Art

[0002] On a gas water heater, micro-nano bubble water is mainly generated by main components such as a gas dissolving chamber, a stop valve, and an air pump.

[0003] During the generation of bubble water, air needs to be continuously consumed. However, when the air volume in the gas dissolving chamber is insufficient, the gas dissolving chamber needs to be refilled with air first, and micro-nano bubble water cannot be continuously generated. The water pressure in the water circuit is usually higher than the air inflation pressure of the air pump. Therefore, it is necessary to use a stop valve to cut off the water circuit and then use the air pump to inflate the gas dissolving chamber. Therefore, during the inflation process, since the water circuit is cut off, the discharged water flow rate is small, and normal water use can only be resumed after the inflation ends and the stop valve is opened.

[0004] At the same time, since the gas dissolving chamber is equivalent to a constant-temperature chamber, the smaller the volume of water in the chamber, the worse the constant-temperature effect. During the inflation process, it is necessary to basically drain the water in the gas dissolving chamber to ensure the best battery life. However, when the amount of water in the gas dissolving chamber for constant temperature is small, the amount of water participating in the mixing of water is insufficient, resulting in a poor constant-temperature effect.

[0005] Since the existing bubble water generation device needs to be inflated when it starts to be used, that is, the water circuit is cut off by a stop valve and inflated by an air pump, however: 1. The existing scheme for generating micro-nano bubble water by inflation cannot continuously use bubble water and needs to cut off the water circuit for air replenishment; 2. During the inflation time, the user's water volume drops significantly and the waiting time is long, affecting the user's water use; 3. After inflation, the amount of water in the gas dissolving chamber is basically drained, and the constant-temperature effect of the gas dissolving chamber is poor; 4. It is not conducive to the popularization and application of bubble water technology on gas water heaters. Summary of the Invention

[0006] This application provides a double-tank constant-temperature bubble water device to solve the problems in the prior art that the water flow is small during the inflation stage of a conventional bubble water device and the constant-temperature effect is poor when the water level in the gas dissolving chamber is low, and to improve the user's bathing comfort.

[0007] In a first aspect, this application provides a double-tank constant-temperature bubble water device, including: a constant-temperature chamber and a gas dissolving chamber. The top of the constant-temperature chamber is connected to the top of the gas dissolving chamber through an upper connecting pipe, and a stop valve is provided on the upper connecting pipe. The bottom of the constant-temperature chamber is connected to the bottom of the gas dissolving chamber through a lower connecting pipe.

[0008] Further, a water inlet pipe is provided at the top of the constant-temperature chamber.

[0009] Furthermore, a baffle is provided inside the constant temperature chamber. The baffle divides the inside of the constant temperature chamber into upper and lower parts. Small holes are provided on the baffle, and the upper connecting pipe is connected to the upper half of the constant temperature chamber.

[0010] Furthermore, the aperture of the small holes on the baffle is smaller than the diameters of the upper connecting pipe and the lower connecting pipe.

[0011] Furthermore, an L-shaped baffle is provided inside the air dissolving chamber. The opening direction of the L-shaped baffle faces the upper connecting pipe, and there is no communication between the top of the L-shaped baffle and the inner top wall of the air dissolving chamber, so as to form a passage between the top of the L-shaped baffle and the top wall of the air dissolving chamber.

[0012] Furthermore, an air inlet pipe is connected to the air dissolving chamber.

[0013] Furthermore, a water outlet pipe is provided at the bottom of the constant temperature chamber and / or the air dissolving chamber.

[0014] Furthermore, when water outlet pipes are provided at the bottoms of both the constant temperature chamber and the air dissolving chamber, the water outlet pipes of the constant temperature chamber and the air dissolving chamber are communicated.

[0015] Furthermore, when the water outlet pipes at the bottoms of the constant temperature chamber and the air dissolving chamber are communicated, no lower connecting pipe is provided for the constant temperature chamber and the air dissolving chamber.

[0016] Furthermore, the stop valve adopts a normally open stop valve.

[0017] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art: 1. The method provided by the embodiment of the present application adopts a double-tank structure. During inflation, the constant temperature chamber replenishes water flow to ensure normal water use by users during the air replenishment process of the bubble water, reduce the waiting time required during the air replenishment state, and improve the bathing comfort.

[0018] 2. By providing small holes on the baffle inside the constant temperature chamber, it is ensured that there is no need to stop water supply for air replenishment during the inflation process, and the continuous use of micro-nano bubble water is realized.

[0019] 3. The constant temperature chamber and the air dissolving chamber are independently arranged to ensure the mixing effect. The water flow is mixed with the water in the tank in the upper half of the constant temperature chamber, and then after passing through the air dissolving chamber, it is mixed with the water in the lower half of the constant temperature chamber for the second time. At the same time, the pressure difference between the upper and lower parts of the constant temperature chamber is used to spray the water flow from the upper half of the constant temperature chamber into the lower half of the constant temperature chamber from the baffle, so as to enhance the mixing disturbance and improve the mixing effect; at the same time, the constant temperature effect of the bubble water device in the low water level state can be effectively improved.

[0020] 4. The air dissolving chamber conducts primary air dissolution in the L-shaped baffle, and after the water level is higher than the top of the L-shaped baffle, it flows into the lower half of the air dissolving chamber and mixes with the air in the tank for secondary air dissolution, enhancing the air dissolution effect.

[0021] 5. By controlling the opening and closing of the stop valve, it can be switched between bubble bath and conventional bath at any time.

[0022] 6. The overall number of components required is small, and the cost is low. Description of the Drawings

[0033] To solve the technical problems in the prior art that the water flow is small during the inflation stage of a conventional bubble water device and the constant temperature effect is poor when the water level in the gas dissolution chamber is low, this application provides a double-tank constant temperature bubble water device, which can replenish the water flow through a constant temperature chamber during the inflation process, ensure the normal water use of users when replenishing air for the bubble water, reduce the waiting time during the air replenishment process, and improve the bathing comfort.

[0034] Figure 1A double-tank constant-temperature bubble water device provided by an embodiment of the present application includes: a constant-temperature tank 1 and a gas-dissolving tank 2. The tops of the constant-temperature tank 1 and the gas-dissolving tank 2 are connected by an upper connecting pipe 3. A stop valve 4 is provided on the upper connecting pipe 3. The bottoms of the constant-temperature tank 1 and the gas-dissolving tank 2 are connected by a lower connecting pipe 5.

[0035] During the working process, the constant-temperature tank 1 and the gas-dissolving tank 2 are respectively used for constant-temperature and gas-filling work. At the same time, the upper connecting pipe 3 and the lower connecting pipe 5 are respectively used to connect the constant-temperature tank 1 and the gas-dissolving tank 2. In this way, during the gas-filling process, the stop valve 4 can be closed to ensure the normal progress of the gas-filling work in the gas-dissolving tank 2. During the gas-filling work of the gas-dissolving tank 2, the constant-temperature tank 1 can simultaneously replenish water to avoid affecting the mixing water and constant-temperature effects due to too low water level in the constant-temperature tank 1.

[0036] In some embodiments, a water inlet pipe 6 is provided at the top of the constant-temperature tank 1. When it is necessary to supplement the water volume in the constant-temperature tank 1, the water inlet pipe 6 can be opened to inject water into the constant-temperature tank 1. Since the water volume will continue to be consumed during the bathing process, generally during the bathing process, water will be continuously supplied to the constant-temperature tank 1 through the water inlet pipe 6, so as to continuously provide constant-temperature bathing water during the user's bathing or bubble bath process, reducing the user's waiting time and improving the bathing experience.

[0037] In some embodiments, a baffle 7 is provided inside the constant-temperature tank 1. The baffle 7 divides the inside of the constant-temperature tank 1 into upper and lower parts. Small holes are provided on the baffle 7. The upper connecting pipe 3 is connected to the upper half of the constant-temperature tank 1. The aperture of the small holes on the baffle 7 is smaller than the diameters of the upper connecting pipe 3 and the lower connecting pipe 5. Since the diameter of the upper connecting pipe 3 is larger than the aperture of the small holes, when the stop valve 4 is in the open state, the water in the upper half of the constant-temperature tank 1 will first enter the gas-dissolving tank 2 through the upper connecting pipe 3. After the stop valve 4 cuts off the water flow, due to the continuous water supply of the water inlet pipe 6, the pressure in the upper half of the constant-temperature tank 1 is greater than that in the lower half, so that the water flow in the upper half cavity sprays into the lower half cavity through the small holes on the baffle 7 to form a supplementary water flow.

[0038] In some embodiments, an L-shaped baffle 8 is provided inside the dissolved air storage bin 2. The opening direction of the L-shaped baffle 8 faces the upper connecting pipe 3, and there is no communication between the top of the L-shaped baffle 8 and the inner top wall of the dissolved air storage bin 2, so as to form a passage between the top of the L-shaped baffle 8 and the top wall of the dissolved air storage bin 2. When water flow is sprayed into the dissolved air storage bin 2, the water flow is blocked by the L-shaped baffle 8, so that the high-speed water flow impacts on the L-shaped baffle 8 and then splashes, mixing with air to form bubble water, realizing the first dissolved air. When the water volume fills the area surrounded by the L-shaped baffle 8, the water level rises to the corresponding position of the top of the L-shaped baffle 8, and then overflows along the L-shaped baffle 8 and falls into the lower half of the dissolved air storage bin 2 in a waterfall shape, so as to carry out the second dissolved air. By providing the L-shaped baffle 8, it can effectively meet the requirement of secondary dissolved air for the water flow entering the dissolved air storage bin 2, thereby generating micro-nano bubble water.

[0039] In some embodiments, an air inlet pipe 9 is connected to the dissolved air storage bin 2. When air needs to be supplemented in the dissolved air storage bin 2, the stop valve 4 is closed to cut off the water flow, and then the dissolved air storage bin 2 is inflated through the air inlet pipe 9, quickly evacuating the dissolved air storage bin 2, and at the same time forming an exhaust water flow that flows back to the constant temperature bin 1 through the lower connecting pipe 5.

[0040] In some embodiments, a water outlet pipe 10 is provided at the bottom of the constant temperature bin 1 and / or the dissolved air storage bin 2.

[0041] According to different embodiments, the water outlet pipe 10 can be arranged at the bottom of the constant temperature bin 1, or the water outlet pipe 10 can be arranged at the bottom of the dissolved air storage bin 2, or water outlet pipes 10 are provided at the bottoms of both the constant temperature bin 1 and the dissolved air storage bin 2.

[0042] Please refer to Figure 1 , in the case where the water outlet pipe 10 is arranged at the bottom of the constant temperature bin 1, when air needs to be supplemented in the dissolved air storage bin 2, an exhaust water flow can be formed by injecting gas and the exhaust water flow is injected into the constant temperature bin 1, and then the water flow is sent out through the water outlet pipe 10 at the bottom of the constant temperature bin 1 for the user to take a bath.

[0043] Please refer to Figure 2 , in the case where the water outlet pipe 10 is arranged at the bottom of the dissolved air storage bin 2, when air needs to be supplemented in the dissolved air storage bin 2, the upper connecting pipe 3 is stopped by the stop valve 4 to prevent water flow from entering the dissolved air storage bin 2. At the same time, the lower connecting pipe 5 is not cut off. Therefore, the water in the lower half of the constant temperature bin 1 will enter the dissolved air storage bin 2 through the lower connecting pipe 5 and be dissolved air once when entering the dissolved air storage bin 2, and then discharged through the water outlet pipe 10 at the bottom of the dissolved air storage bin 2, so as to ensure that water supply is still maintained during the inflation process and avoid the situation that the water output is small during the inflation process and the user needs to wait.

[0044] Please refer to Figure 3, when the water outlet pipe 10 is provided at the bottom of the constant temperature bin 1 and the gas dissolving bin 2 at the same time, the constant temperature bin 1 is connected to the water outlet pipe 10 of the gas dissolving bin 2, and the constant temperature bin 1 and the gas dissolving bin 2 are not provided with the lower connecting pipe 5. When the gas dissolving bin 2 needs to be replenished, the upper connecting pipe 3 is stopped by the stop valve 4 to prevent water from entering the gas dissolving bin 2. When the gas dissolving bin 2 is replenished and inflated, the water in the gas dissolving bin 2 will be formed into an exhaust water flow to rush out the water outlet pipe 10 connected to the bottom of the gas dissolving bin 2. At the same time, the water in the lower half of the constant temperature bin 1 is discharged from the water outlet pipe 10 connected to the bottom of the constant temperature bin 1. The water flow discharged from the constant temperature bin 1 and the water flow discharged from the gas dissolving bin 2 converge at the intersection of the water outlet pipe 10, and the mixed water flow is output.

[0045] In some embodiments, the stop valve 4 is a normally open stop valve 4. Under normal conditions, the stop valve 4 is in an open state, and the water flow in the constant temperature chamber 1 can be sent to the gas dissolving chamber 2 through the upper connecting pipe 3, so as to achieve gas dissolution and generate micro-nano bubble water. When the gas content in the gas dissolving chamber 2 is low and inflation is required, the stop valve 4 is closed and the upper connecting pipe 3 is cut off, so as to facilitate gas replenishment in the gas dissolving chamber 2 to meet the inflation demand.

[0046] The specific workflow of this application is described below through three specific embodiments: 1.Please refer to Figure 1 In the first embodiment provided in the present application, a water outlet pipe 10 is provided at the bottom of the constant temperature chamber 1, and the constant temperature chamber 1 and the lower half of the gas dissolving chamber 2 are connected through the lower connecting pipe 5. The use process of the bubble water is divided into two processes: the gas replenishment process when the air in the gas dissolving chamber 2 is insufficient, and the normal use of the bubble water, wherein: Bubble water replenishment process: In this mode, the stop valve 4 is closed and the air inlet pipe 9 is opened. The stop valve 4 closes the passage of the upper connecting pipe 3, and at the same time, the air dissolving chamber 2 is inflated through the air inlet pipe 9, and the air dissolving chamber 2 is quickly emptied by blowing gas. At the same time, an exhaust water flow is formed in the lower connecting pipe 5, and the exhaust water flow is merged into the constant temperature chamber 1 through the lower connecting pipe 5. After the water flow of the upper connecting pipe 3 is cut off, the internal pressure of the upper cavity of the constant temperature chamber 1 is greater than the pressure of the lower cavity, so that the water flow in the upper cavity is sprayed into the lower cavity through the small holes on the baffle 7 to form a replenishing water flow. By adjusting the aperture size of the small holes, the exhaust water flow plus the replenishing water flow are within the range of the normal water flow rate, ensuring the normal water consumption of the user during the inflation process. After the inflation reaches the set time, the inflation state of the air inlet pipe 9 is disconnected, the stop valve 4 is opened, and the device uses bubble water normally.

[0047] Water usage process for sparkling water: In this mode, the stop valve 4 is opened and the air inlet pipe 9 is closed. In this state, the air dissolving chamber 2 is filled with air. The diameters of the upper connecting pipe 3 and the lower connecting pipe 5 are larger than the aperture diameters of the small holes on the baffle 7 in the constant temperature chamber 1. The water flowing into the upper half of the constant temperature chamber 1 mainly enters the air dissolving chamber 2 through the upper connecting pipe 3 connected to the constant temperature chamber 1. After the water flow is sprayed into the air dissolving chamber 2, it impacts on the L-shaped baffle 8 in the air dissolving chamber 2, generating sputtering and mixing with the air to form sparkling water, completing one air dissolution. When the water level at the L-shaped baffle 8 is higher than the top of the L-shaped baffle 8, the overflowing water falls down in a waterfall shape to the lower half of the air dissolving chamber 2, agitating the water in the lower half of the air dissolving chamber 2 and mixing air into the water for secondary air dissolution. The water flow with a large amount of dissolved bubbles enters the constant temperature chamber 1 through the lower connecting pipe 5 and mixes with the water in the constant temperature chamber 1. At the same time, since the pressure in the upper half of the constant temperature chamber 1 is relatively larger than that in the lower half, the water in the upper half will be sprayed into the lower half through the small holes on the baffle 7 for secondary water mixing. After completing the water mixing, the water flow is discharged through the water outlet pipe 10 at the bottom of the constant temperature chamber 1.

[0048] Water volume balance during water usage and air replenishment: During the normal water usage process, the stop valve 4 is in the normally open state. Under the national standard conditions, the normal water consumption of this gas water heater is measured and recorded as A L / min. During the air replenishment process, the stop valve 4 is closed, and the water drainage flow rate during inflation is recorded as B L / min (i.e., the water flow rate of the lower connecting pipe 5), and the water spraying flow rate through the small holes on the baffle 7 is recorded as C L / min. Adjust the cross-sectional area of the small holes on the baffle 7 so that the water flow rate B + C = A, that is, the water flow rates at the water outlet during the water usage process and the inflation process are equal, realizing the water flow balance during the water usage and air replenishment processes.

[0049] Among them, the national standard refers to GB 6932-2015 "Domestic Gas Instantaneous Water Heater", which stipulates the relevant requirements and test methods for gas water heaters, including the determination of normal water consumption, etc. In this national standard, generally 15°C is used as the standard inlet water temperature and 0.05 MPa is used as the standard water pressure. Under this unified test condition, the normal water consumption of the gas water heater is determined by measuring the amount of hot water output per unit time of the gas water heater, ensuring the comparability and accuracy of the test results.

[0050] Conventional bathing mode: In this mode, the stop valve 4 is normally open and the air inlet pipe 9 is closed. Both the constant temperature chamber 1 and the air dissolving chamber 2 are filled with water. At this time, the air dissolving chamber 2 is equivalent to the second constant temperature chamber 1, and the water flow direction is the same as that in the water usage process for sparkling water. In the conventional bathing mode, the water flow undergoes the first water mixing in the upper half cavity of the constant temperature chamber 1, the second water mixing in the air dissolving chamber 2, and the third water mixing in the lower half of the constant temperature chamber 1. During the third water mixing, due to the water pressure difference between the upper and lower parts of the constant temperature chamber 1, the water sprayed out through the small holes on the baffle 7 participates in the third water mixing disturbance, enhancing the water mixing effect, and then flows out through the water outlet pipe 10 after the water mixing.

[0051] II. Please refer to Figure 2 In the second embodiment provided in this application, a water outlet pipe 10 is provided at the bottom of the air dissolving chamber 2, and the lower half of the constant temperature chamber 1 and the air dissolving chamber 2 are communicated through a lower connecting pipe 5. The process of using the bubble water is divided into an air supplementing process when the air in the air dissolving chamber 2 is insufficient and a normal water using process for the bubble water, where: Air supplementing process for bubble water: In this mode, the stop valve 4 is closed and the air inlet pipe 9 is opened. The stop valve 4 closes the passage of the upper connecting pipe 3, and at the same time, the air dissolving chamber 2 is inflated through the air inlet pipe 9. The air dissolving chamber 2 is quickly emptied by the blowing of the gas, and an exhaust water flow is formed in the water outlet pipe 10. At the same time, the pressure inside the upper half of the constant temperature chamber 1 is greater than the pressure inside the lower half of the chamber, so that the water flow inside the upper half of the chamber sprays into the lower half of the chamber through the small holes on the baffle 7, forming a supplementary water flow. The lower connecting pipe 5 is not cut off. Therefore, the supplementary water flow in the lower half of the constant temperature chamber 1 will enter the air dissolving chamber 2 through the lower connecting pipe 5, converge with the exhaust water flow in the lower half of the air dissolving chamber 2, and then be discharged through the water outlet pipe 10 at the bottom of the air dissolving chamber 2. By adjusting the aperture size of the small holes, the exhaust water flow plus the supplementary water flow are within the normal water using flow range, ensuring the normal water consumption of users during the inflation process. After the inflation reaches the set time, the inflation state of the air inlet pipe 9 is disconnected, the stop valve 4 is opened, and the device normally uses the bubble water.

[0052] Water using process for bubble water: In this mode, the stop valve 4 is opened and the air inlet pipe 9 is closed. In this state, the air dissolving chamber 2 is filled with air. The diameters of the upper connecting pipe 3 and the lower connecting pipe 5 are relatively larger than the aperture of the small holes on the baffle 7 inside the constant temperature chamber 1. The water flow entering the upper half of the constant temperature chamber 1 mainly enters the air dissolving chamber 2 through the upper connecting pipe 3 connected to the constant temperature chamber 1. After the water flow sprays into the air dissolving chamber 2, it impacts on the L-shaped baffle 8 inside the air dissolving chamber 2, generating sputtering and mixing with the air to form bubble water, completing one air dissolving process. When the water level at the L-shaped baffle 8 is higher than the top of the L-shaped baffle 8, the overflowing water falls in a waterfall shape to the lower half of the air dissolving chamber 2, agitating the water in the lower half of the air dissolving chamber 2 and mixing air into the water, performing a secondary air dissolving process. At the same time, since the pressure in the upper half of the constant temperature chamber 1 is relatively greater than that in the lower half, the water in the upper half will be sprayed into the lower half through the small holes on the baffle 7, performing a primary water mixing process. The water in the lower half of the constant temperature chamber 1 will enter the air dissolving chamber 2 through the lower connecting pipe 5 and be secondarily mixed with the water containing a large amount of bubbles. After the water mixing is completed, the water flow will be discharged through the water outlet pipe 10 at the bottom of the constant temperature chamber 1.

[0053] Water balance during water use and air supplementation: During normal water use, the stop valve 4 is in the normally open state. Under national standard conditions, the normal water consumption of this gas water heater is measured and recorded as A L / min. During the air supplementation process, the stop valve 4 is closed. The water drainage flow rate during air inflation is recorded as B L / min (i.e., the water flow rate of the water outlet pipe 10 connected to the bottom of the air dissolving chamber 2), and the water flow rate ejected from the small holes on the baffle 7 is recorded as C L / min. Adjust the cross-sectional area of the small holes on the baffle 7 so that the water flow rate B + C = A, that is, the water flow rates at the water outlet during the water use process and the air inflation process are equal, realizing the water flow balance during water use and air supplementation.

[0054] Among them, the national standard refers to GB 6932-2015 "Household Gas Instantaneous Water Heater". This standard stipulates the relevant requirements and test methods for gas water heaters, including the determination of normal water consumption, etc. In this national standard, generally 15°C is used as the standard inlet water temperature and 0.05 MPa is used as the standard water pressure. Under this unified test condition, the normal water consumption of the gas water heater is determined by measuring the amount of hot water output per unit time, ensuring the comparability and accuracy of the test results.

[0055] Conventional bathing mode: In this mode, the stop valve 4 is normally open and the intake pipe 9 is closed. Both the constant temperature chamber 1 and the air dissolving chamber 2 are filled with water. At this time, the air dissolving chamber 2 is equivalent to the second constant temperature chamber 1, and the water flow direction is the same as that during the use of bubble water. In the conventional bathing mode, the water flow undergoes the first mixing in the upper half cavity of the constant temperature chamber 1, the second mixing in the air dissolving chamber 2, and the third mixing in the lower half of the air dissolving chamber 2. Before the third mixing, due to the water pressure difference between the upper and lower parts of the constant temperature chamber 1, the water ejected from the small holes on the baffle 7 undergoes mixing disturbance, enhancing the mixing effect, and then flows out from the water outlet pipe 10 after mixing.

[0056] III. Please refer to Figure 3 In the third embodiment provided in this application, water outlet pipes 10 are provided at the bottoms of both the constant temperature chamber 1 and the air dissolving chamber 2, and they are connected through the water outlet pipes 10 of the constant temperature chamber 1 and the air dissolving chamber 2 for water discharge. The process of using bubble water includes the air supplementation process when there is insufficient air in the air dissolving chamber 2 and the normal water use process of bubble water. Among them: Bubble water replenishment process: In this mode, the stop valve 4 is closed and the intake pipe 9 is opened. The stop valve 4 closes the passage of the upper connecting pipe 3, and at the same time, the air storage chamber 2 is inflated through the intake pipe 9. The air storage chamber 2 is quickly emptied by the blowing of the gas. At the same time, an exhaust water flow is formed in the water outlet pipe 10 connected to the bottom of the air storage chamber 2, and the exhaust water flow is merged into the water outlet pipe 10 connected to the bottom of the air storage chamber 2 through the lower connecting pipe 5. After cutting off the water flow in the upper connecting pipe 3, the pressure inside the upper half cavity of the constant temperature chamber 1 is greater than that of the lower half cavity, so that the water flow in the upper half cavity is sprayed into the lower half cavity through the small holes on the baffle 7, forming a supplementary water flow and merging into the water outlet pipe 10 connected to the bottom of the constant temperature chamber 1. By adjusting the aperture size of the small holes, the exhaust water flow plus the supplementary water flow is within the range of the normal water consumption flow rate, ensuring the normal water consumption of users during the inflation process. After the inflation reaches the set time, the inflation state of the intake pipe 9 is disconnected, the stop valve 4 is opened, and the device normally uses bubble water.

[0057] Bubble water usage process: In this mode, the stop valve 4 is opened and the intake pipe 9 is closed. In this state, the air storage chamber 2 is filled with air. The diameter of the upper connecting pipe 3 is relatively larger than the aperture of the small holes on the baffle 7 in the constant temperature chamber 1. The water flow entering the upper half of the constant temperature chamber 1 mainly enters the air storage chamber 2 through the upper connecting pipe 3 connected to the constant temperature chamber 1. After the water flow is sprayed into the air storage chamber 2, it impacts on the L-shaped baffle 8 in the air storage chamber 2, generating sputtering and mixing with the air to form bubble water, completing one-time air dissolution. When the water level at the L-shaped baffle 8 is higher than the top of the L-shaped baffle 8, the overflowing water falls in a waterfall shape to the lower half of the air storage chamber 2, stirring the water in the lower half of the air storage chamber 2 and mixing air into the water, performing secondary air dissolution. The water flow with a large amount of dissolved bubbles enters the water outlet pipe 10 connected to the bottom of the air storage chamber 2. At the same time, since the pressure in the upper half of the constant temperature chamber 1 is relatively larger than that in the lower half, the water in the upper half will be sprayed into the lower half through the small holes on the baffle 7 for primary water mixing. Then the water in the lower half of the constant temperature chamber 1 enters the water outlet pipe 10 connected to the bottom of the constant temperature chamber 1 and is mixed with the water flow with a large amount of dissolved bubbles sent from the air storage chamber 2 into the water outlet pipe 10. After completing the water mixing, it will be discharged along the water outlet pipe 10.

[0058] Water volume balance during water usage and air replenishment: During normal water usage, the stop valve 4 is in the normally open state. The normal water consumption of this gas water heater is measured under national standards and recorded as A L / min. During the air replenishment process, the stop valve 4 is closed, and the drainage water flow rate during inflation is recorded as B L / min (i.e., the water flow rate of the water outlet pipe 10 connected to the bottom of the air storage chamber 2), and the water flow rate sprayed out through the small holes on the baffle 7 is recorded as C L / min. Adjust the cross-sectional area of the small holes on the baffle 7 so that the water flow rate B + C = A, that is, the water flow rates at the water outlet during the water usage process and the inflation process are equal, realizing the water flow balance during water usage and air replenishment.

[0059] Among them, the national standard refers to GB 6932-2015 "Domestic Gas Instantaneous Water Heater", which stipulates the relevant requirements and test methods for gas water heaters, including the determination of normal water consumption, etc. In this national standard, generally 15°C is used as the standard inlet water temperature and 0.05 MPa is used as the standard water pressure. Under such unified test conditions, the normal water consumption is determined by measuring the amount of hot water output by the gas water heater per unit time, ensuring the comparability and accuracy of test results.

[0060] Conventional bathing mode: In this mode, the cut-off valve 4 is always open and the air inlet pipe 9 is closed. Both the constant temperature chamber 1 and the air dissolving chamber 2 are filled with water. At this time, the air dissolving chamber 2 is equivalent to the second constant temperature chamber 1, and the water flow direction is the same as that in the process of using bubble water. In the conventional bathing mode, the water flow undergoes the first mixing in the upper half cavity of the constant temperature chamber 1, the second mixing in the air dissolving chamber 2, and the third mixing after converging in the outlet pipes 10 of the air dissolving chamber 2 and the constant temperature chamber 1. Before the third mixing, due to the water pressure difference between the upper and lower parts of the constant temperature chamber 1, the water sprayed out from the small holes of the baffle 7 undergoes mixing disturbance, enhancing the mixing effect. After the mixing is completed in the outlet pipe 10, the water flow is sent out.

[0061] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art: 1. The method provided by the embodiments of the present application adopts a double-tank structure, and the water flow is supplemented through the constant temperature chamber 1 during inflation, ensuring the normal water use of users during the air supplement process of bubble water, reducing the waiting time required in the air supplement state, and improving the bathing comfort.

[0062] 2. By setting small holes on the baffle 7 inside the constant temperature chamber 1, it is ensured that there is no need to stop water for air supplement during the inflation process, realizing the continuous use of micro-nano bubble water.

[0063] 3. The constant temperature chamber 1 and the air dissolving chamber 2 are independently arranged to ensure the mixing effect. The water flow is mixed with the water in the tank in the upper half of the constant temperature chamber 1, and then after passing through the air dissolving chamber 2, it is mixed with the water in the lower half of the constant temperature chamber 1 for the second time. At the same time, the water flow is sprayed from the upper half of the constant temperature chamber 1 into the lower half of the constant temperature chamber 1 from the baffle 7 by using the pressure difference between the upper and lower parts of the constant temperature chamber 1, thereby enhancing the mixing disturbance and improving the mixing effect; at the same time, the constant temperature effect of the bubble water device under the low water level state can be effectively improved.

[0064] 4. The air dissolving chamber 2 performs primary air dissolution in the L-shaped baffle 8, and after the water level is higher than the top of the L-shaped baffle 8, it flows into the lower half of the air dissolving chamber 2 to be mixed with the air in the tank for secondary air dissolution, enhancing the air dissolution effect.

[0065] 5. Through the opening and closing control of the cut-off valve 4, the switching between bubble bath and conventional bathing can be carried out at any time.

[0066] 6. The overall number of components required is small, and the cost is low.
