Description

Technical Field

[0001] The present application relates to the technical field of gas water heaters, and in particular to a double-tank constant temperature bubbling water device. Background Art

[0002] In a gas water heater, micro-nano bubble water is mainly produced through major components such as the air dissolving chamber, stop valve, and air pump.

[0003] The production of sparkling water requires continuous air consumption. However, when the air volume in the air dissolving chamber is insufficient, the chamber must be refilled, preventing the continuous production of micro-nano bubble water. The water pressure is usually higher than the air pump's inflation pressure, so a shutoff valve is required to shut off the water flow before the air pump can inflate the air dissolving chamber. Therefore, during the inflation process, the water flow is cut off, resulting in a low discharge rate. It is necessary to wait for inflation to complete and open the shutoff valve before using the water.

[0004] At the same time, since the dissolved air 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, the water in the dissolved air chamber needs to be basically emptied to ensure the best endurance. However, if the water volume in the dissolved air chamber used for constant temperature is small, the amount of water involved in mixing is insufficient, resulting in poor constant temperature effect.

[0005] When the existing bubble water generating device is used, it needs to be inflated, that is, the water path is cut off by a stop valve and an air pump is used for inflation. However:

[0006] 1. The existing solution of aerating micro-nano bubble water cannot continuously use the bubble water and requires cutting off the water line for aeration;

[0007] 2. During the inflation time, the user's water consumption drops significantly, and the waiting time is long, which affects the user's water use;

[0008] 3. After inflation, the water in the dissolved air chamber is basically drained, and the constant temperature effect of the dissolved air chamber is poor;

[0009] 4. It is not conducive to the promotion and application of bubble water technology in gas water heaters. Summary of the Invention

[0010] The present application provides a double-tank constant temperature bubble water device to solve the problems in the prior art of small water flow during the inflation phase of conventional bubble water devices and poor constant temperature effect when the water level in the dissolved air tank is low, thereby improving the bathing comfort of users.

[0011] In the first aspect, the present application provides a double-tank constant temperature bubble water device, comprising: a constant temperature chamber and a dissolved air chamber, the constant temperature chamber and the top of the dissolved air chamber are connected by an upper connecting pipe, and a stop valve is provided on the upper connecting pipe, and the constant temperature chamber and the bottom of the dissolved air chamber are connected by a lower connecting pipe.

[0012] Furthermore, a water inlet pipe is provided on the top of the constant temperature chamber.

[0013] Furthermore, a baffle is provided inside the constant temperature chamber, and the baffle divides the interior of the constant temperature chamber into two parts, an upper part and an lower part. A small hole is provided on the baffle, and the upper connecting pipe is connected to the upper half of the constant temperature chamber.

[0014] Furthermore, the diameter of the small holes on the baffle is smaller than the diameters of the upper connecting pipe and the lower connecting pipe.

[0015] Furthermore, an L-shaped baffle is provided inside the gas dissolving bin, the opening direction of the L-shaped baffle is toward the upper connecting pipe, and the top of the L-shaped baffle is not connected to the internal top wall of the gas dissolving bin, thereby forming a passage between the top of the L-shaped baffle and the top wall of the gas dissolving bin.

[0016] Furthermore, the air dissolving bin is connected to an air inlet pipe.

[0017] Furthermore, a water outlet pipe is provided at the bottom of the constant temperature chamber and / or the dissolved air chamber.

[0018] Furthermore, when water outlet pipes are provided at the bottom of the constant temperature bin and the gas dissolving bin, the water outlet pipes of the constant temperature bin and the gas dissolving bin are connected.

[0019] Furthermore, when the water outlet pipes at the bottom of the constant temperature bin and the gas dissolving bin are connected, the constant temperature bin and the gas dissolving bin are not provided with a lower connecting pipe.

[0020] Furthermore, the stop valve is a normally open stop valve.

[0021] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0022] 1. The method provided in the embodiment of the present application adopts a double-tank structure, and replenishes the water flow through the constant temperature chamber during inflation, thereby ensuring the normal water use of the user during the process of replenishing the bubble water, reducing the waiting time required in the replenishment state, and improving bathing comfort.

[0023] 2. By setting small holes on the baffle inside the constant temperature chamber, it is ensured that there is no need to stop water and replenish air during the inflation process, so that the continuous use of micro-nano bubble water can be achieved.

[0024] 3. The constant temperature chamber and the dissolved air chamber are set up independently to ensure the water mixing effect. The water flow is mixed with the water in the tank in the upper part of the constant temperature chamber, and then mixed with the water in the lower part of the constant temperature chamber for the second time after passing through the dissolved air chamber. 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 part of the constant temperature chamber to the lower part of the constant temperature chamber through the baffle, so as to enhance the water mixing disturbance and improve the water mixing effect; at the same time, it can effectively improve the constant temperature effect of the bubble water device under low water level state.

[0025] 4. The air dissolving chamber dissolves air once 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, thereby enhancing the air dissolving effect.

[0026] 5. By opening and closing the stop valve, you can switch between bubble bath and regular bath at any time.

[0027] 6. Fewer parts are required as a whole, and the cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0037] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0038] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like.

[0039] In order to solve the technical problems in the prior art that the water flow in conventional bubble water devices is small during the inflation stage and the constant temperature effect is poor when the water level in the dissolved air tank is low, the present application provides a double-tank constant temperature bubble water device, which can replenish the water flow through the constant temperature tank during the inflation process, ensure the normal water use of users when replenishing the bubble water, reduce the waiting time during the replenishment process, and improve bathing comfort.

[0040] Figure 1A double-tank constant temperature bubbling water device provided in an embodiment of the present application includes: a constant temperature chamber 1 and a dissolved air chamber 2, the top of the constant temperature chamber 1 and the dissolved air chamber 2 are connected by an upper connecting pipe 3, and a stop valve 4 is provided on the upper connecting pipe 3, and the bottom of the constant temperature chamber 1 and the dissolved air chamber 2 are connected by a lower connecting pipe 5.

[0041] During operation, the constant temperature chamber 1 and the air dissolving chamber 2 are used to maintain constant temperature and to inflate the gas. At the same time, the upper connecting pipe 3 and the lower connecting pipe 5 are used to connect the constant temperature chamber 1 and the air dissolving chamber 2. During the inflation process, the shut-off valve 4 can be closed to ensure normal inflation in the air dissolving chamber 2. During the inflation process in the air dissolving chamber 2, the constant temperature chamber 1 can be replenished with water simultaneously to prevent the water level in the constant temperature chamber 1 from being too low, which could affect the water mixing and constant temperature.

[0042] In some embodiments, a water inlet pipe 6 is provided at the top of the constant temperature chamber 1. When the constant temperature chamber 1 needs to be replenished with water, the water inlet pipe 6 can be opened to inject water into the constant temperature chamber 1. Since water is continuously consumed during bathing, water is generally continuously supplied to the constant temperature chamber 1 through the water inlet pipe 6 during the bathing process. This continuously provides constant temperature bathing water during the user's bath or bubble bath, reducing user waiting time and improving the bathing experience.

[0043] In some embodiments, a baffle 7 is provided inside the constant temperature chamber 1. The baffle 7 divides the interior of the constant temperature chamber 1 into two parts, an upper part and an lower part. A small hole is provided on the baffle 7, and the upper connecting pipe 3 is connected to the upper half of the constant temperature chamber 1. The aperture of the small hole on the baffle 7 is smaller than the diameter 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 hole, when the stop valve 4 is open, the water in the upper half of the constant temperature chamber 1 will first enter the gas dissolving chamber 2 through the upper connecting pipe 3. After the stop valve 4 cuts off the water flow, since the water inlet pipe 6 continues to supply water, the pressure in the upper half of the constant temperature chamber 1 is greater than the pressure in the lower half, so that the water flow in the upper half cavity is sprayed into the lower half cavity through the small hole on the baffle 7, forming a complementary water flow.

[0044] In some embodiments, an L-shaped baffle 8 is provided inside the gas dissolving bin 2, and the opening direction of the L-shaped baffle 8 is toward the upper connecting pipe 3. The top of the L-shaped baffle 8 is not connected to the inner top wall of the gas dissolving bin 2, thereby forming a passage between the top of the L-shaped baffle 8 and the top wall of the gas dissolving bin 2. When water flows into the gas dissolving bin 2, the water flow is blocked by the L-shaped baffle 8, so that the high-speed water flow impacts the L-shaped baffle 8 and then splashes, mixing with the air to form bubble water, thereby achieving the first gas dissolution. When the water volume fills the area surrounded by the L-shaped baffle 8, the water level rises to a position corresponding to the top of the L-shaped baffle 8, thereby overflowing along the L-shaped baffle 8 and falling into the lower half of the gas dissolving bin 2 in a waterfall shape, thereby performing a second gas dissolution. By providing the L-shaped baffle 8, the water flow entering the gas dissolving bin 2 can be effectively dissolved for the second time, thereby producing micro-nano bubble water.

[0045] In some embodiments, the air dissolving chamber 2 is connected to an air inlet pipe 9. When air needs to be added to the air dissolving chamber 2, the stop valve 4 is closed to cut off the water flow, and then the air dissolving chamber 2 is inflated through the air inlet pipe 9, quickly emptying the air dissolving chamber 2, and at the same time, an exhaust water flow is formed to flow back to the constant temperature chamber 1 through the lower connecting pipe 5.

[0046] In some embodiments, a water outlet pipe 10 is provided at the bottom of the constant temperature chamber 1 and / or the dissolved air chamber 2 .

[0047] According to different embodiments, the water outlet pipe 10 can be set at the bottom of the constant temperature chamber 1, or the water outlet pipe 10 can be set at the bottom of the dissolved air chamber 2, or water outlet pipes 10 can be set at the bottom of both the constant temperature chamber 1 and the dissolved air chamber 2.

[0048] See also Figure 1 When the water outlet pipe 10 is arranged at the bottom of the constant temperature chamber 1, when the dissolved air chamber 2 needs to be replenished with air, an exhaust water flow can be formed by injecting gas, and the exhaust water flow can be injected into the constant temperature chamber 1, and then the water flow is sent out through the water outlet pipe 10 at the bottom of the constant temperature chamber 1 to supply the user with bathing.

[0049] See also Figure 2 In the case where the water outlet pipe 10 is arranged at the bottom of the air dissolving chamber 2, when the air dissolving chamber 2 needs to be replenished, the upper connecting pipe 3 is stopped by the stop valve 4 to prevent water from entering the air dissolving chamber 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 chamber 1 will enter the air dissolving chamber 2 through the lower connecting pipe 5, and will dissolve air once when entering the air dissolving chamber 2, and then be discharged through the water outlet pipe 10 at the bottom of the air dissolving chamber 2. In this way, water supply is maintained during the inflation process, avoiding the situation where the water output is small during the inflation process and the user needs to wait.

[0050] See also Figure 3, when the water outlet pipe 10 is simultaneously provided at the bottom of the constant temperature bin 1 and the air dissolving bin 2, the constant temperature bin 1 is connected to the water outlet pipe 10 of the air dissolving bin 2, and the constant temperature bin 1 and the air dissolving bin 2 are not provided with the lower connecting pipe 5. When air needs to be replenished in the air dissolving bin 2, the upper connecting pipe 3 is stopped by the stop valve 4 to prevent water from entering the air dissolving bin 2. When air is replenished and inflated in the air dissolving bin 2, the water in the air dissolving bin 2 will be formed into an exhaust water flow and pushed out of the water outlet pipe 10 connected to the bottom of the air 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 air dissolving bin 2 converge at the intersection of the water outlet pipe 10, and the mixed water flow is output.

[0051] In some embodiments, the stop valve 4 is a normally open stop valve 4. Under normal conditions, the stop valve 4 is in the 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, thereby dissolving gas and generating 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, thereby facilitating gas replenishment in the gas dissolving chamber 2 to meet the inflation demand.

[0052] The following three specific examples illustrate the specific workflow of this application:

[0053] 1. Please refer to Figure 1 In the first embodiment provided in this 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 air dissolving chamber 2 are connected via a lower connecting pipe 5. The use process of the sparkling water is divided into two processes: the air replenishment process when the air dissolving chamber 2 is insufficient, and the normal use of the sparkling water.

[0054] 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 the 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 half of the constant temperature chamber 1 is greater than the pressure of the lower half of the cavity, so that the water flow in the upper half of the cavity is sprayed into the lower half of the cavity through the small holes on the baffle 7, forming a replenishing water flow. By adjusting the aperture size of the small holes, the exhaust water flow and 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.

[0055] The process of using bubble water: In this mode, the stop valve 4 is open 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 small hole diameter of 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 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 will impact the L-shaped baffle 8 in the air dissolving chamber 2, thereby generating splashes and mixing with air to form bubble water, completing the first gas 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 to the lower half of the air dissolving chamber 2 in a waterfall shape, stirring the water in the lower half of the air dissolving chamber 2 and mixing air into the water, performing a secondary gas dissolution. The water flow that dissolves a large amount of 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 part of the constant temperature chamber 1 is greater than that in the lower part, the water in the upper part will be sprayed into the lower part through the small holes in the baffle 7, causing secondary water mixing. After the water mixing is completed, the water will be discharged through the outlet pipe 10 at the bottom of the constant temperature chamber 1.

[0056] Water balance during water use and gas replenishment: During normal water use, shutoff valve 4 is normally open. The normal water consumption of the gas water heater is measured under national standards and recorded as AL / min. During the gas replenishment process, shutoff valve 4 is closed. The drainage flow rate during aeration is recorded as BL / min (i.e., the water flow rate of lower connecting pipe 5), and the water flow rate sprayed out of the small hole in baffle 7 is recorded as CL / min. The cross-sectional area of ​​the small hole in baffle 7 is adjusted to ensure that the water flow rate B + C = A. That is, the water flow rate at the water outlet during water use and aeration is equal, achieving water flow balance during water use and gas replenishment.

[0057] The national standard refers to GB 6932-2015, "Household Gas Instantaneous Water Heaters," which specifies requirements and test methods for gas water heaters, including the determination of normal water consumption. This national standard generally uses 15°C as the standard water inlet temperature and 0.05 MPa as the standard water pressure. Under these standardized test conditions, the normal water consumption of a gas water heater is determined by measuring the amount of hot water it outputs per unit time, ensuring comparability and accuracy of test results.

[0058] Conventional bathing mode: In this mode, the stop valve 4 is normally open and the air inlet pipe 9 is closed. The interior of the constant temperature chamber 1 and the air dissolving chamber 2 are both filled with water. At this time, the air dissolving chamber 2 is equivalent to the second constant temperature chamber 1, and the direction of water flow is consistent with the water use process of bubble water. In conventional bathing mode, the water flow is mixed for the first time in the upper half of the constant temperature chamber 1, mixed for the second time in the air dissolving chamber 2, and mixed for the third time in the lower half of the constant temperature chamber 1. At the same time as the third water mixing, due to the difference in water pressure between the upper and lower parts of the constant temperature chamber 1, the water sprayed from the small holes of the baffle 7 participates in the third water mixing disturbance, thereby enhancing the water mixing effect, and flows out from the outlet pipe 10 after mixing.

[0059] 2. 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 constant temperature chamber 1 and the lower half of the air dissolving chamber 2 are connected via a lower connecting pipe 5. The use process of the bubble water is divided into two processes: the air replenishment process when the air in the air dissolving chamber 2 is insufficient, and the normal use of the bubble water.

[0060] 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. The air dissolving chamber 2 is quickly emptied by the blowing of gas, forming an exhaust water flow in the outlet pipe 10. At the same time, the internal pressure of the upper half of the constant temperature chamber 1 is greater than the pressure of the lower half of the chamber, so that the water flow in the upper half of the chamber is sprayed into the lower half of the chamber through the small holes on the baffle 7, forming a replenishment water flow. The lower connecting pipe 5 is not cut off, so the replenishment 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, merge with the exhaust water flow in the lower half of the air dissolving chamber 2, and then be discharged through the 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 and the replenishment water flow are within the range of normal water flow, 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 uses the bubble water normally.

[0061] Sparkling Water Usage Process: In this mode, the shutoff valve 4 is open 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 apertures of the baffle 7 within the constant temperature chamber 1. Water entering the upper half of the constant temperature chamber 1 primarily flows through the upper connecting pipe 3, which connects to the constant temperature chamber 1, and into the air dissolving chamber 2. After the water is sprayed into the air dissolving chamber 2, it impacts the L-shaped baffle 8 within the chamber 2, creating splashes that mix with air to form bubbling water, completing the primary air dissolution. When the water level at the L-shaped baffle 8 exceeds the top of the L-shaped baffle 8, the overflowing water cascades down to the lower half of the air dissolving chamber 2, agitating the water there and mixing air into the water, thus achieving secondary air dissolution. Simultaneously, because the pressure in the upper half of the constant temperature chamber 1 is higher than that in the lower half, the water from the upper half is sprayed into the lower half through the apertures in the baffle 7, causing a primary mixing of the water. The water in the lower half of the constant temperature chamber 1 enters the air dissolving chamber 2 through the lower connecting pipe 5 and is mixed with the water containing a large number of bubbles. After the water mixing is completed, the water flow is discharged through the outlet pipe 10 at the bottom of the constant temperature chamber 1.

[0062] Water balance during water use and gas replenishment: During normal water use, shutoff valve 4 is normally open. The normal water consumption of the gas water heater is measured under national standards and recorded as AL / min. During the gas replenishment process, shutoff valve 4 is closed. The drainage flow rate during aeration is recorded as BL / min (i.e., the flow rate of water in outlet pipe 10 connected to the bottom of dissolved gas chamber 2). The flow rate of water sprayed from the small hole in baffle 7 is recorded as CL / min. The cross-sectional area of ​​the small hole in baffle 7 is adjusted to ensure that water flow rate B + C = A. That is, the water flow rate at the water outlet during water use and aeration is equal, achieving water flow balance during water use and gas replenishment.

[0063] The national standard refers to GB 6932-2015, "Household Gas Instantaneous Water Heaters," which specifies requirements and test methods for gas water heaters, including the determination of normal water consumption. This national standard generally uses 15°C as the standard water inlet temperature and 0.05 MPa as the standard water pressure. Under these standardized test conditions, the normal water consumption of a gas water heater is determined by measuring the amount of hot water it outputs per unit time, ensuring comparability and accuracy of test results.

[0064] Conventional bathing mode: In this mode, the stop valve 4 is normally open and the air inlet pipe 9 is closed. The interior of the constant temperature chamber 1 and the air dissolving chamber 2 are both filled with water. At this time, the air dissolving chamber 2 is equivalent to the second constant temperature chamber 1, and the direction of water flow is consistent with the water use process of bubble water. In conventional bathing mode, the water flow is mixed for the first time in the upper half of the constant temperature chamber 1, mixed for the second time in the air dissolving chamber 2, and mixed for the third time in the lower half of the air dissolving chamber 2. Before the third mixing, due to the difference in water pressure between the upper and lower parts of the constant temperature chamber 1, the water sprayed from the small holes of the baffle 7 is disturbed by mixing, thereby enhancing the mixing effect, and then flows out from the outlet pipe 10 after mixing.

[0065] 3. Please refer to Figure 3 In the third embodiment provided in this application, a water outlet pipe 10 is provided at the bottom of the constant temperature chamber 1 and the air dissolving chamber 2, and the water is discharged through the water outlet pipe 10 of the constant temperature chamber 1 and the air dissolving chamber 2. The use process of the bubble water is divided into two processes: the air replenishment process when the air dissolving chamber 2 is insufficient, and the normal use of the bubble water.

[0066] Bubble Replenishment Process: In this mode, the shutoff valve 4 is closed and the air inlet pipe 9 is open. The shutoff valve 4 closes the passage to the upper connecting pipe 3, while simultaneously inflating the air dissolving chamber 2 through the air inlet pipe 9. This blowing of gas rapidly empties the air dissolving chamber 2, simultaneously forming an exhaust flow in the outlet pipe 10 connected to the bottom of the air dissolving chamber 2. This exhaust flow is then channeled through the lower connecting pipe 5 into the outlet pipe 10 connected to the bottom of the air dissolving chamber 2. After the water flow in the upper connecting pipe 3 is cut off, the internal pressure in the upper chamber of the constant temperature chamber 1 exceeds that in the lower chamber, causing the water in the upper chamber to spray into the lower chamber through the small holes in the baffle 7, forming a replenishment flow that flows into the outlet pipe 10 connected to the bottom of the constant temperature chamber 1. By adjusting the aperture size of the small holes, the exhaust and replenishment flows are within the normal water flow range, ensuring normal water consumption for the user during the inflation process. After the set inflation time is reached, the air inlet pipe 9 is disconnected, the shutoff valve 4 is opened, and the device begins normal use of the bubble water.

[0067] The process of using bubble water: In this mode, the stop valve 4 is open and the air inlet pipe 9 is closed. In this state, the air dissolving bin 2 is full of air. The diameter of the upper connecting pipe 3 is larger than the diameter of the small hole of the baffle 7 in the constant temperature bin 1. The water flow entering the upper half of the constant temperature bin 1 mainly enters the air dissolving bin 2 through the upper connecting pipe 3 connected to the constant temperature bin 1. After the water flow is sprayed into the air dissolving bin 2, it will impact the L-shaped baffle 8 in the air dissolving bin 2, thereby generating splashing and mixing with air to form bubble water, completing one gas 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 to the lower half of the air dissolving bin 2 in a waterfall shape, stirring the water in the lower half of the air dissolving bin 2 and mixing air into the water for secondary gas dissolution. The water flow that dissolves a large amount of bubbles enters the outlet pipe 10 connected to the bottom of the air dissolving bin 2. At the same time, because the pressure in the upper half of constant temperature chamber 1 is higher than that in the lower half, the water in the upper half is sprayed into the lower half through the small holes in baffle 7, causing mixing. The water in the lower half of constant temperature chamber 1 then enters the outlet pipe 10 connected to the bottom of constant temperature chamber 1, where it mixes with the water flow from the air dissolution chamber 2 into the outlet pipe 10, which has dissolved a large number of bubbles. After mixing, the water is discharged through the outlet pipe 10.

[0068] Water balance during water use and gas replenishment: During normal water use, shutoff valve 4 is normally open. The normal water consumption of the gas water heater is measured under national standards and recorded as AL / min. During the gas replenishment process, shutoff valve 4 is closed. The drainage flow rate during aeration is recorded as BL / min (i.e., the flow rate of water in outlet pipe 10 connected to the bottom of dissolved gas chamber 2). The flow rate of water sprayed from the small hole in baffle 7 is recorded as CL / min. The cross-sectional area of ​​the small hole in baffle 7 is adjusted to ensure that water flow rate B + C = A. That is, the water flow rate at the water outlet during water use and aeration is equal, achieving water flow balance during water use and gas replenishment.

[0069] The national standard refers to GB 6932-2015, "Household Gas Instantaneous Water Heaters," which specifies requirements and test methods for gas water heaters, including the determination of normal water consumption. This national standard generally uses 15°C as the standard water inlet temperature and 0.05 MPa as the standard water pressure. Under these standardized test conditions, the normal water consumption of a gas water heater is determined by measuring the amount of hot water it outputs per unit time, ensuring comparability and accuracy of test results.

[0070] Conventional bathing mode: In this mode, the stop valve 4 is normally open and the air inlet pipe 9 is closed. The interior of the constant temperature chamber 1 and the air dissolving chamber 2 are both filled with water. At this time, the air dissolving chamber 2 is equivalent to the second constant temperature chamber 1, and the direction of water flow is consistent with the water use process of bubble water. In conventional bathing mode, the water flow is mixed for the first time in the upper half of the constant temperature chamber 1, mixed for the second time in the air dissolving chamber 2, and mixed for the third time after converging in the outlet pipe 10 of the air dissolving chamber 2 and the constant temperature chamber 1. Before the third mixing, due to the difference in water pressure between the upper and lower parts of the constant temperature chamber 1, the water sprayed from the small holes of the baffle 7 is disturbed by mixing, thereby enhancing the mixing effect. After the water mixing is completed in the outlet pipe 10, the water flow is sent out.

[0071] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0072] 1. The method provided in the embodiment of the present application adopts a double-tank structure, and the water flow is replenished through the constant temperature chamber 1 during inflation, thereby ensuring the normal water use of the user during the process of replenishing the bubble water, reducing the waiting time required in the replenishment state, and improving bathing comfort.

[0073] 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 replenishment during the inflation process, so that the continuous use of micro-nano bubble water can be achieved.

[0074] 3. The constant temperature bin 1 and the dissolved air bin 2 are independently set to ensure the water mixing effect. The water flow is mixed with the water in the tank in the upper part of the constant temperature bin 1, and then mixed with the water in the lower part of the constant temperature bin 1 for the second time after passing through the dissolved air bin 2. At the same time, the pressure difference between the upper and lower parts of the constant temperature bin 1 is used to spray the water flow from the upper part of the constant temperature bin 1 to the lower part of the constant temperature bin 1 through the baffle 7, so as to enhance the water mixing disturbance and improve the water mixing effect; at the same time, it can effectively improve the constant temperature effect of the bubble water device in the low water level state.

[0075] 4. The air dissolving chamber 2 is subjected to a primary air dissolving 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 and mixes with the air in the tank for a secondary air dissolving, thereby enhancing the air dissolving effect.

[0076] 5. By opening and closing the stop valve 4, you can switch between bubble bath and regular bath at any time.

[0077] 6. Fewer parts are required as a whole, and the cost is lower.
