Description

[Technical Field]

[0001] The present application relates to the technical field of gas water heaters, and in particular to a double-tank type thermostatic bubble water device. [Background technology]

[0002] In gas water heaters, micro-nano bubble water is mainly generated by major components such as the gas dissolution tank, shut-off valve, and air pump.

[0003] The process of generating bubble water requires constant air consumption. If the amount of air in the gas dissolving tank is insufficient, the gas dissolving tank must first be replenished with gas, preventing the continuous generation of micro-nano bubble water. Because the water channel pressure is usually higher than the gas filling pressure of the air pump, the water channel must be shut off with a shutoff valve before the air pump can fill the gas dissolving tank with gas. As a result, the water channel is shut off during gas filling, reducing the water flow rate. After gas filling is complete, the shutoff valve must be opened before the water can be used normally.

[0004] At the same time, because the gas dissolving tank is equivalent to a thermostatic tank, the smaller the water volume in the tank, the worse the thermostatic effect. To ensure the longest possible usage time, the water in the gas dissolving tank must be almost completely drained during gas filling. However, if the amount of water in the thermostatic tank is small, there will not be enough water to mix with the water, resulting in a poor thermostatic effect.

[0005] When starting to use a conventional bubble water generating device, it is necessary to fill the device with gas, i.e., shut off the water channel with a shutoff valve and fill the device with gas using an air pump. 1. The conventional method of generating micro-nano bubble water by filling with gas cannot continuously supply bubble water, and it is necessary to block the water channel and replenish the gas. 2. When filling gas, the amount of water consumed by the user drops significantly, resulting in a longer waiting time and affecting the user's water consumption. 3. After gas is filled, the water in the gas dissolving tank is almost completely discharged, which reduces the constant temperature effect of the gas dissolving tank. 4. The spread of bubble water technology to gas water heaters is hindered. Summary of the Invention [Problem to be solved by the invention]

[0006] The present application solves the problem of poor thermostatic effect in conventional bubble water devices when the water flow is small during the gas filling stage and the water level in the gas dissolution tank is low in the prior art, and provides a double-tank thermostatic bubble water device that improves the user's bathing comfort. [Means for solving the problem]

[0007] In a first aspect, the present application provides a double-tank type thermostatic bubble water apparatus, which includes a thermostatic tank and a gas dissolving tank, the tops of the thermostatic tank and the gas dissolving tank being connected by an upper connecting pipe, the upper connecting pipe being equipped with a shut-off valve, and the bottoms of the thermostatic tank and the gas dissolving tank being connected by a lower connecting pipe.

[0008] Furthermore, a water inlet pipe is provided at the top of the thermostatic tank.

[0009] Furthermore, a baffle plate is provided inside the thermostatic tank, which divides the interior of the thermostatic tank into two parts, an upper part and an lower part. Small holes are provided in the baffle plate, and the upper connecting pipe is connected to the upper half of the thermostatic tank.

[0010] Furthermore, the diameter of the small holes in the baffle plate is smaller than the diameter of the upper and lower connecting pipes.

[0011] Furthermore, an L-shaped baffle plate is provided inside the gas dissolution tank, and the opening of the L-shaped baffle plate faces the upper connecting pipe, and there is no communication between the top of the L-shaped baffle plate and the inner top wall of the gas dissolution tank, thereby forming a passage between the top of the L-shaped baffle plate and the top wall of the gas dissolution tank.

[0012] Furthermore, an intake pipe is connected to the gas dissolution tank.

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

[0014] Furthermore, when the constant temperature tank and the gas dissolving tank are provided with water outlet pipes at their bottoms, the water outlet pipes of the constant temperature tank and the gas dissolving tank communicate with each other.

[0015] Furthermore, when the outlet pipes at the bottoms of the thermostatic tank and the gas dissolving tank are connected to each other, the thermostatic tank and the gas dissolving tank are not provided with a lower connecting pipe.

[0016] Furthermore, a normally open shutoff valve is used as the shutoff valve. [Effects of the Invention]

[0017] The above-described technical aspects of the embodiments of the present application have the following advantages over the prior art. 1. The device according to the embodiment of the present application uses a double tank structure, and the water flow is replenished by a constant temperature tank during gas filling, ensuring that the user can use the water normally while gas is being added to the bubble water, shortening the waiting time required during gas addition, and improving bathing comfort. 2. By providing small holes in the baffle plate inside the thermostatic tank, there is no need to stop the water supply to replenish the gas even while the gas is being filled, allowing for continuous use of micro-nano bubble water. 3. The thermostatic tank and gas dissolution tank are installed separately to ensure the water mixing effect. The water mixes with the water in the upper half of the thermostatic tank, then passes through the gas dissolution tank and mixes with the water in the lower half of the thermostatic tank. The pressure difference between the upper and lower halves of the thermostatic tank is used to inject water from the upper half of the thermostatic tank into the lower half through a baffle plate, strengthening the mixing and stirring of the water and improving the mixing effect. This also effectively improves the thermostatic effect of the bubble water device when the water level is low. 4. In the gas dissolution tank, the primary gas dissolution is carried out through the L-shaped baffle plate. After the water level exceeds the top of the L-shaped baffle plate, it flows into the lower half of the gas dissolution tank and mixes with the air in the tank to carry out secondary gas dissolution, thereby improving the gas dissolution effect. 5. By controlling the opening and closing of the shutoff valve, you can switch between bubble bath and normal bath at any time. 6. Fewer parts are required overall, resulting in lower costs.

[0022] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in combination with the accompanying drawings in the embodiments of the present application. It is clear that the described embodiments do not represent all the embodiments of the present application, but only some of the embodiments of the present application. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any creative work belong to the scope of protection of the present application.

[0023] In the following disclosure, various embodiments or examples are provided to realize different structures of the present application. To simplify the disclosure of the present application, components and installations in specific examples will be described below. Of course, these are merely illustrative and are not intended to limit the present application. Furthermore, the present application may repeatedly refer to numbers and / or letters in different examples. Such repetition is for the sake of simplicity and clarity and does not in itself dictate a relationship between the respective embodiments and / or installations described.

[0024] For ease of explanation, the specification may use spatially relative terms to describe the relative position or movement of one element or feature shown in the drawings relative to other elements or features. These relative terms may include, for example, "interior," "exterior," "inside," "outside," "underside," "upper," "above," "front," "rear," and the like. Such spatially relative terms are intended to encompass different positions of the device during use or operation than the orientation depicted in the drawings. For example, if the device in the drawings undergoes a positional or orientational change or a change in movement, the directional designations will change accordingly. For example, an element depicted as "underside other elements or features" or "under other elements or features" will be oriented below as "on top of other elements or features" or "above other elements or features." Thus, a term exemplified as "under..." can encompass an orientation of being above or below. A device may be otherwise oriented (rotated 90 degrees or otherwise oriented), and the spatially relative descriptors used in the specification should be interpreted accordingly.

[0025] In order to solve the technical problems of conventional bubble water devices in the prior art, where the water flow is small during the gas filling stage and the constant temperature effect is poor when the water level in the gas dissolution tank is low, the present application provides a double-tank constant temperature bubble water device that uses a constant temperature tank to replenish the water flow during gas filling, ensuring that users can use the water normally during gas replenishment for the bubble water, reducing the waiting time during gas replenishment, and improving bathing comfort.

[0026] FIG. 1 shows a double-tank type thermostatic bubble water device according to an embodiment of the present application, which includes a thermostatic tank 1 and a gas dissolution tank 2, the tops of which are connected by an upper connecting pipe 3, the upper connecting pipe 3 is equipped with a shut-off valve 4, and the bottoms of which are connected by a lower connecting pipe 5.

[0027] During operation, the thermostatic tank 1 and the gas dissolution tank 2 perform the thermostatic and gas filling operations, respectively, and the upper connecting pipe 3 and the lower connecting pipe 5 connect the thermostatic tank 1 and the gas dissolution tank 2, respectively, so that during the gas filling process, the shutoff valve 4 is closed to ensure the normal progress of the gas filling operation in the gas dissolution tank 2. During the gas filling process in the gas dissolution tank 2, water can be replenished in the thermostatic tank 1 synchronously, thereby avoiding the water level in the thermostatic tank 1 being too low, which would affect the water mixing and thermostatic effect.

[0028] In some embodiments, a water inlet pipe 6 is provided at the top of the thermostatic tank 1. When the thermostatic tank 1 needs to be replenished with water, the water inlet pipe 6 can be opened to inject water into the thermostatic tank 1. Since water is continuously consumed during bathing, water is typically continuously supplied into the thermostatic tank 1 through the water inlet pipe 6, thereby providing a continuous supply of constant-temperature bathing water while the user is enjoying a normal bath or bubble bath, reducing the user's waiting time and improving the bathing experience.

[0029] In some embodiments, a baffle plate 7 is provided inside the thermostatic tank 1. The baffle plate 7 divides the interior of the thermostatic tank 1 into two sections, an upper section and an lower section. Small holes are provided in the baffle plate 7, and the upper connecting pipe 3 is connected to the upper half of the thermostatic tank 1. The diameter of the small holes in the baffle plate 7 is smaller than the diameters of the upper connecting pipe 3 and the lower connecting pipe 5. Because the diameter of the upper connecting pipe 3 is larger than the diameter of the small holes, when the shutoff valve 4 is open, the water in the upper half of the thermostatic tank 1 first flows into the gas dissolution tank 2 through the upper connecting pipe 3. After the shutoff valve 4 blocks the water flow, the water inlet pipe 6 continues to supply water, causing the pressure in the upper half of the thermostatic tank 1 to exceed the pressure in the lower half. This causes the water flow in the upper half to be injected into the lower half through the small holes in the baffle plate 7, forming a make-up water flow.

[0030] In some embodiments, an L-shaped baffle plate 8 is installed inside the gas dissolution tank 2, with its opening facing the upper connecting pipe 3. The top of the L-shaped baffle plate 8 is not connected to the interior top wall of the gas dissolution tank 2, thereby forming a passage between the top of the L-shaped baffle plate 8 and the top wall of the gas dissolution tank 2. When water is injected into the gas dissolution tank 2, the L-shaped baffle plate 8 blocks the water flow. This causes the high-speed water to collide with the L-shaped baffle plate 8 and splash, mixing with the air to form bubbled water, achieving the first gas dissolution. After the area surrounded by the L-shaped baffle plate 8 is filled with water, the water level rises to a position corresponding to the top of the L-shaped baffle plate 8, overflows along the L-shaped baffle plate 8, and falls like a waterfall into the lower half of the gas dissolution tank 2, thereby performing the second gas dissolution. By providing the L-shaped baffle plate 8, secondary gas dissolution can be effectively performed on the water flow that has flowed into the gas dissolution tank 2, thereby generating micro-nano bubble water.

[0031] In some embodiments, an intake pipe 9 is connected to the gas dissolution tank 2. When gas needs to be replenished in the gas dissolution tank 2, the shutoff valve 4 is turned off to block the water flow, and then gas is filled into the gas dissolution tank 2 through the intake pipe 9, rapidly emptying the gas dissolution tank 2. At the same time, the exhaust water flow formed returns to the constant temperature tank 1 through the lower connecting pipe 5.

[0032] In some embodiments, a water outlet pipe 10 is provided at the bottom of the constant temperature tank 1 and / or the gas dissolution tank 2.

[0033] In different embodiments, the outlet pipe 10 is provided at the bottom of the constant temperature tank 1, or the outlet pipe 10 is provided at the bottom of the gas dissolution tank 2, or the outlet pipes 10 are provided at the bottom of the constant temperature tank 1 and the gas dissolution tank 2, respectively.

[0034] As shown in FIG. 1, when the water outlet pipe 10 is installed at the bottom of the thermostatic tank 1, when it is necessary to replenish the gas in the gas dissolution tank 2 with gas, the gas is filled to form an exhaust water flow, which is then injected into the thermostatic tank 1, and the water flow is then discharged through the water outlet pipe 10 at the bottom of the thermostatic tank 1 to supply the user with water for bathing.

[0035] As shown in FIG. 2, when outlet pipe 10 is installed at the bottom of gas dissolution tank 2, when gas needs to be added to gas dissolution tank 2, upper connecting pipe 3 is shut off by shutoff valve 4 to prevent water from flowing into gas dissolution tank 2. At the same time, lower connecting pipe 5 is not shut off, so the water in the lower half of thermostatic tank 1 flows into gas dissolution tank 2 through lower connecting pipe 5 and undergoes primary gas dissolution upon entering gas dissolution tank 2. It is then discharged through outlet pipe 10 at the bottom of gas dissolution tank 2, ensuring a continuous supply of water during gas filling and avoiding the situation where the water flow rate is low and the user has to wait.

[0036] As shown in FIG. 3, when outlet pipes 10 are installed at the bottoms of both thermostatic tank 1 and gas dissolution tank 2, thermostatic tank 1 and gas dissolution tank 2 are connected, and no lower connecting pipe 5 is installed between thermostatic tank 1 and gas dissolution tank 2. When gas needs to be refilled into gas dissolution tank 2, upper connecting pipe 3 is shut off by shutoff valve 4, preventing water from flowing into gas dissolution tank 2. When gas is refilled into gas dissolution tank 2, the water in gas dissolution tank 2 forms an exhaust water flow and is forced out through outlet pipe 10 connected to the bottom of gas dissolution tank 2. Simultaneously, the lower half of the water in thermostatic tank 1 is discharged through outlet pipe 10 connected to the bottom of thermostatic tank 1. The water flows discharged from thermostatic tank 1 and gas dissolution tank 2 merge at the confluence of outlet pipe 10, and the combined water flow is discharged.

[0037] In some embodiments, a normally-open shutoff valve 4 is used as the shutoff valve 4, and in a normal state, the shutoff valve 4 is in an on state, allowing the water flow in the thermostatic tank 1 to be sent to the gas dissolution tank 2 via the upper connecting pipe 3, thereby realizing gas dissolution and generating micro-nano bubble water. When the gas content in the gas dissolution tank 2 is low and gas filling is required, the shutoff valve 4 is turned off and the upper connecting pipe 3 is closed, thereby facilitating gas replenishment in the gas dissolution tank 2 and meeting the gas filling requirement.

[0038] The specific operation flow of the present invention will be explained below using three specific examples.

[0039] (one) 1, in the first embodiment of the present invention, a water outlet pipe 10 is provided at the bottom of the thermostatic tank 1, and the thermostatic tank 1 communicates with the lower half of the gas dissolving tank 2 via a lower connecting pipe 5. The process of using bubble water can be divided into two steps: a process of replenishing gas when there is a shortage of air in the gas dissolving tank 2, and a process of using bubble water normally.

[0040] In this mode, the shutoff valve 4 is turned off and the intake pipe 9 is turned on during the process of adding gas to the bubble water. The shutoff valve 4 closes the upper connecting pipe 3, and simultaneously the intake pipe 9 fills the gas dissolution tank 2 with gas, rapidly emptying the tank. At the same time, an exhaust water flow is formed in the lower connecting pipe 5, which then flows into the thermostatic tank 1. When the water flow in the upper connecting pipe 3 is shut off, the internal pressure of the upper half of the thermostatic tank 1 is greater than that of the lower half. Therefore, the water flow in the upper half is forced through the small holes in the baffle plate 7 into the lower half, forming a replenishment water flow. The diameter of the small holes is adjusted to ensure that the sum of the exhaust water flow and the replenishment water flow is within the normal water consumption range, ensuring the user's normal water consumption during the gas filling process. After the gas filling reaches the set time, the gas filling state of the intake pipe 9 is turned off, the shut-off valve 4 is turned on, and the device can use the bubble water normally.

[0041] During the bubble water usage mode, the shutoff valve 4 is turned on and the intake pipe 9 is turned off. In this state, the gas dissolution tank 2 is filled with air. The diameters of the upper and lower connecting pipes 3 and 5 are larger than the diameter of the small holes in the baffle plate 7 inside the thermostatic tank 1. The water flowing into the upper half of the thermostatic tank 1 primarily flows into the gas dissolution tank 2 via the upper connecting pipe 3 connected to the thermostatic tank 1. After the water enters the gas dissolution tank 2, it collides with the L-shaped baffle plate 8 inside the gas dissolution tank 2, splashes, and mixes with the air to form bubble water, completing the primary gas dissolution. If the water level at the L-shaped baffle plate 8 is higher than the top of the L-shaped baffle plate 8, the overflowing water falls like a waterfall into the lower half of the gas dissolution tank 2, stirring the water in the lower half of the gas dissolution tank 2 and introducing air into the water, resulting in secondary gas dissolution. The water flow containing a large amount of dissolved air bubbles flows through the lower connecting pipe 5 into the thermostatic tank 1 and mixes with the water in the thermostatic tank 1. At the same time, because the pressure in the upper half of the thermostatic tank 1 is higher than that in the lower half, the water in the upper half is injected into the lower half through small holes in the baffle plate 7, causing secondary water mixing. After the water mixing is complete, the water flow is discharged from the outlet pipe 10 at the bottom of the thermostatic tank 1.

[0042] Regarding the balance of water volume during the water usage and gas refilling processes, during normal water usage, the shutoff valve 4 is always on, and when it complies with the Chinese national standard, the normal water usage of the gas water heater is measured and is set to AL / min. During gas refilling, the shutoff valve 4 is turned off, the drain flow rate during gas filling is BL / min (i.e., the water flow rate of the lower connecting pipe 5), the water flow rate sprayed from the small holes in the baffle plate 7 is CL / min, and by adjusting the cross-sectional area of ​​the small holes in the baffle plate 7, the water flow rate B+C=A, that is, the water flow rate from the water outlet is equal during the water usage process and the gas refilling process, and the water flow rate balance during the water usage and gas refilling processes is achieved.

[0043] The Chinese national standard here refers to GB6932-2015 "Domestic Gas Quick Water Heater," which specifies the relevant requirements and test methods for gas water heaters, including the measurement of normal water consumption. This Chinese national standard generally sets the standard inlet water temperature at 15°C and the standard water pressure at 0.05MPa, and therefore determines the normal water consumption by measuring the amount of hot water supplied per unit time by a gas water heater under standardized test conditions, ensuring the comparability and accuracy of the test results.

[0044] In the normal bathing mode, the shutoff valve 4 is always on and the intake pipe 9 is off. The thermostatic tank 1 and the gas dissolving tank 2 are both filled with water. The gas dissolving tank 2 corresponds to the second thermostatic tank 1, and the water flow direction corresponds to the water usage process of the bubble water. In the normal bathing mode, the water flows through the upper half of the thermostatic tank 1 to perform the first water mixing, the gas dissolving tank 2 to perform the second water mixing, and the lower half of the thermostatic tank 1 to perform the third water mixing. During the third water mixing, the water pressure difference between the upper and lower halves of the thermostatic tank 1 causes water to be sprayed through the small holes in the baffle plate 7, which contributes to the third water mixing and stirring, improving the water mixing effect. After the water is mixed, it flows out of the outlet pipe 10.

[0045] (two) 2, in the second embodiment of the present invention, a water outlet pipe 10 is provided at the bottom of the gas dissolving tank 2, and the constant temperature tank 1 and the lower half of the gas dissolving tank 2 are connected via a lower connecting pipe 5. The process of using bubble water can be divided into two steps: a process of replenishing gas when there is a shortage of air in the gas dissolving tank 2, and a process of using bubble water normally.

[0046] In this mode, the shutoff valve 4 is turned off and the intake pipe 9 is turned on to add gas to the bubble water. The shutoff valve 4 closes the upper connecting pipe 3, and the intake pipe 9 simultaneously fills the gas dissolution tank 2 with gas. The gas is then blown in, rapidly emptying the tank and forming a discharge water flow through the outlet pipe 10. At the same time, because the internal pressure of the upper half of the thermostatic tank 1 is greater than that of the lower half, the water flowing from the upper half is injected into the lower half through the small holes in the baffle plate 7, forming a replenishment water flow. Because the lower connecting pipe 5 is open, the replenishment water flowing from the lower half of the thermostatic tank 1 flows through the lower connecting pipe 5 into the gas dissolution tank 2, where it merges with the discharged water flow from the lower half of the gas dissolution tank 2 and is then discharged through the outlet pipe 10 at the bottom of the gas dissolution tank 2. By adjusting the diameter of the small holes, the sum of the exhaust water flow and the refill water flow is within the normal water consumption range, ensuring the user's normal water consumption during gas filling. After the gas filling time has reached the set time, the gas filling state of the intake pipe 9 is turned off, the shut-off valve 4 is turned on, and the device can use bubble water normally.

[0047] During the bubble water usage mode, the shutoff valve 4 is turned on and the intake pipe 9 is turned off. In this state, the gas dissolution tank 2 is filled with air. The diameters of the upper and lower connecting pipes 3 and 5 are larger than the diameter of the small holes in the baffle plate 7 inside the thermostatic tank 1. The water flowing into the upper half of the thermostatic tank 1 primarily flows into the gas dissolution tank 2 via the upper connecting pipe 3 connected to the thermostatic tank 1. After the water enters the gas dissolution tank 2, it collides with the L-shaped baffle plate 8 inside the gas dissolution tank 2, splashes, and mixes with the air to form bubble water, completing the primary gas dissolution. If the water level at the L-shaped baffle plate 8 is higher than the top of the L-shaped baffle plate 8, the overflowing water falls like a waterfall into the lower half of the gas dissolution tank 2, stirring the water in the lower half of the gas dissolution tank 2 and introducing air into the water, resulting in secondary gas dissolution. At the same time, because the pressure in the upper half of the thermostatic tank 1 is higher than that in the lower half, the water in the upper half is injected into the lower half through small holes in the baffle plate 7, causing primary water mixing. The water in the lower half of the thermostatic tank 1 flows into the gas dissolution tank 2 through the lower connecting pipe 5, where it undergoes secondary mixing with the water containing a large amount of dissolved air bubbles. After the water mixing is complete, the water flow is discharged from the outlet pipe 10 at the bottom of the thermostatic tank 1.

[0048] Regarding the balance of water volume during the water usage and gas refilling processes, during normal water usage, the shutoff valve 4 is always on, and when it complies with the Chinese national standard, the normal water usage of the gas water heater is measured and is set to AL / min. During gas refilling, the shutoff valve 4 is turned off, the drain flow rate during gas filling is BL / min (i.e., the water flow rate of the water outlet 10 connected to the bottom of the gas dissolution tank 2), the water flow rate sprayed from the small holes in the baffle plate 7 is CL / min, and by adjusting the cross-sectional area of ​​the small holes in the baffle plate 7, the water flow rate B + C = A, that is, the water flow rate from the water outlet is equal during the water usage process and the gas refilling process, achieving a balance of water flow volume during the water usage and gas refilling processes.

[0049] The Chinese national standard here refers to GB6932-2015 "Domestic Gas Quick Water Heater," which specifies the relevant requirements and test methods for gas water heaters, including the measurement of normal water consumption. This Chinese national standard generally sets the standard inlet water temperature at 15°C and the standard water pressure at 0.05MPa, and therefore determines the normal water consumption by measuring the amount of hot water supplied per unit time by a gas water heater under standardized test conditions, ensuring the comparability and accuracy of the test results.

[0050] In the normal bathing mode, the shutoff valve 4 is always on and the intake pipe 9 is off. The thermostatic tank 1 and the gas dissolving tank 2 are both filled with water. The gas dissolving tank 2 corresponds to the second thermostatic tank 1, and the water flow direction corresponds to the water usage process of the bubble water. In the normal bathing mode, the water flows through the upper half of the thermostatic tank 1 for the first water mixing, the gas dissolving tank 2 for the second water mixing, and the lower half of the gas dissolving tank 2 for the third water mixing. Before the third water mixing, the water is sprayed through the small holes in the baffle plate 7 due to the water pressure difference between the upper and lower halves of the thermostatic tank 1, mixing and stirring the water, improving the water mixing effect. After mixing, the water flows out of the outlet pipe 10.

[0051] (three) 3, in the third embodiment of the present invention, the thermostatic tank 1 and the gas dissolving tank 2 are each provided at their bottoms with a water outlet pipe 10, which is connected to the water outlet pipes 10 of the thermostatic tank 1 and the gas dissolving tank 2 to discharge water. The process of using bubble water can be divided into two steps: a process of replenishing gas when there is a shortage of air in the gas dissolving tank 2, and a process of using bubble water normally.

[0052] In this mode, the shutoff valve 4 is turned off and the intake pipe 9 is turned on during the process of adding gas to the bubble water. The shutoff valve 4 turns off the passage of the upper connecting pipe 3, and simultaneously the intake pipe 9 fills the gas dissolution tank 2 with gas, rapidly emptying the tank 2 through the gas injection. At the same time, an exhaust water flow is formed in the outlet pipe 10 connected to the bottom of the gas dissolution tank 2, and the exhaust water flow is merged into the outlet pipe 10 connected to the bottom of the gas dissolution tank 2 through the lower connecting pipe 5. After the water flow in the upper connecting pipe 3 is shut off, the internal pressure of the upper half of the thermostatic tank 1 is greater than that of the lower half, so the water flow in the upper half is injected into the lower half through the small holes in the baffle plate 7, forming a replenishment water flow that merges into the outlet pipe 10 connected to the bottom of the thermostatic tank 1. By adjusting the diameter of the small holes, the sum of the exhaust water flow and the refill water flow is within the normal water consumption range, ensuring the user's normal water consumption during gas filling. After the gas filling time has reached the set time, the gas filling state of the intake pipe 9 is turned off, the shut-off valve 4 is turned on, and the device can use bubble water normally.

[0053] During the bubble water usage mode, the shutoff valve 4 is turned on and the intake pipe 9 is turned off. In this state, the gas dissolution tank 2 is filled with air. The diameter of the upper connecting pipe 3 is larger than the diameter of the small holes in the baffle plate 7 inside the thermostatic tank 1. The water flowing into the upper half of the thermostatic tank 1 primarily flows into the gas dissolution tank 2 via the upper connecting pipe 3 connected to the thermostatic tank 1. After the water enters the gas dissolution tank 2, it collides with the L-shaped baffle plate 8 inside the gas dissolution tank 2, splashes, and mixes with the air to form bubble water, completing the primary gas dissolution. If the water level at the L-shaped baffle plate 8 is higher than the top of the L-shaped baffle plate 8, the overflowing water falls like a waterfall into the lower half of the gas dissolution tank 2, stirring the water in the lower half of the gas dissolution tank 2 and introducing air into the water, resulting in secondary gas dissolution. The water flow with a large amount of dissolved air bubbles flows into the outlet pipe 10 connected to the bottom of the gas dissolution tank 2. At the same time, because the pressure in the upper half of the thermostatic tank 1 is higher than that in the lower half, the water in the upper half is sprayed into the lower half through small holes in the baffle plate 7, causing primary water mixing. Then, the water in the lower half of the thermostatic tank 1 flows into the outlet pipe 10 connected to the bottom of the thermostatic tank 1 and mixes with the water flow with a large amount of dissolved air bubbles that has been sent from the gas dissolution tank 2 to the outlet pipe 10. After the water has been mixed, it is discharged along the outlet pipe 10.

[0054] Regarding the balance of water volume during the water usage and gas refilling processes, during normal water usage, the shutoff valve 4 is always on, and when it complies with the Chinese national standard, the normal water usage of the gas water heater is measured and is set to AL / min. During gas refilling, the shutoff valve 4 is turned off, the drain flow rate during gas filling is BL / min (i.e., the water flow rate of the water outlet 10 connected to the bottom of the gas dissolution tank 2), the water flow rate sprayed from the small holes in the baffle plate 7 is CL / min, and by adjusting the cross-sectional area of ​​the small holes in the baffle plate 7, the water flow rate B + C = A, that is, the water flow rate from the water outlet is equal during the water usage process and the gas refilling process, achieving a balance of water flow volume during the water usage and gas refilling processes.

[0055] The Chinese national standard here refers to GB6932-2015 "Domestic Gas Quick Water Heater," which specifies the relevant requirements and test methods for gas water heaters, including the measurement of normal water consumption. This Chinese national standard generally sets the standard inlet water temperature at 15°C and the standard water pressure at 0.05MPa, and therefore determines the normal water consumption by measuring the amount of hot water supplied per unit time by a gas water heater under standardized test conditions, ensuring the comparability and accuracy of the test results.

[0056] In the normal bathing mode, the shutoff valve 4 is always on and the intake pipe 9 is off. The thermostatic tank 1 and the gas dissolving tank 2 are both filled with water. The gas dissolving tank 2 corresponds to the second thermostatic tank 1, and the water flow direction corresponds to the water usage process of the bubble water. In the normal bathing mode, the water flows through the upper half of the thermostatic tank 1, mixing the water a first time, then mixing the water a second time in the gas dissolving tank 2, and finally merging at the outlet pipe 10 of the thermostatic tank 2 and the thermostatic tank 1 to achieve the third water mixing. Before the third water mixing, the water pressure difference between the upper and lower halves of the thermostatic tank 1 causes water to be sprayed through the small holes in the baffle plate 7, mixing and stirring the water, improving the water mixing effect. After the water mixing is completed at the outlet pipe 10, the water flow is discharged.

[0057] The above-described technical aspects of the embodiments of the present application have the following advantages over the prior art. 1. The device according to the embodiment of the present application uses a double-tank structure, and the water flow is replenished by the thermostatic tank 1 during gas filling. This ensures that the user can use the water normally during the gas filling process for the bubble water, shortens the waiting time required for gas filling, and improves bathing comfort. 2. By providing small holes in the baffle plate 7 inside the thermostatic tank 1, there is no need to stop the water supply to replenish the gas even during gas filling, making it possible to continuously use micro-nano bubble water. 3. The thermostatic tank 1 and gas dissolution tank 2 are installed independently to ensure the water mixing effect. The water mixes with the water in the upper half of the thermostatic tank 1, then passes through the gas dissolution tank 2 and performs secondary water mixing with the water in the lower half of the thermostatic tank 1. The pressure difference between the upper and lower halves of the thermostatic tank 1 is used to inject water from the upper half of the thermostatic tank 1 into the lower half through the baffle plate 7, thereby strengthening water mixing and stirring, improving the water mixing effect, and effectively improving the thermostatic effect of the bubble water device when the water level is low. 4. In the gas dissolution tank 2, primary gas dissolution is carried out at the L-shaped baffle plate 8. After the water level exceeds the top of the L-shaped baffle plate 8, the water flows into the lower half of the gas dissolution tank 2 and mixes with the air in the tank to carry out secondary gas dissolution, thereby improving the gas dissolution effect. 5. By controlling the opening and closing of the shutoff valve 4, the bubble bath and the normal bath can be switched at any time. 6. Fewer parts are required overall, resulting in lower costs.
