The present invention provides a dissolved air tank 10.

In an embodiment of the present invention, as shown in fig. 1 and 2, the dissolved air tank 10 includes:

the tank body comprises a tank body wall 100 with a dissolved air cavity 200, and a water inlet hole and a water outlet hole are formed in the tank body wall 100;

the water inlet pipe 300 is arranged in the water inlet hole and at least partially extends into the gas dissolving cavity 200;

the water outlet pipe 400 is arranged at the water outlet hole; and

and one end of the air inlet pipe 700 is communicated with an air source, and the other end of the air inlet pipe is communicated with the air dissolving cavity 200.

In the present invention, the normal water in the external pipe enters the air dissolving chamber 200 through the water inlet pipe 300, and is fully mixed with the air in the air dissolving chamber 200 to form air dissolving water, and the air dissolving water is discharged out of the air dissolving chamber 200 through the water outlet pipe 400 to flow to other devices at the rear end through the external pipe, and finally micro bubble water can be generated at the water using end. In addition, the air inlet pipe 700 is communicated with the air source and the air dissolving cavity 200, so that the air source can convey air in the air dissolving cavity 200, the air in the air dissolving cavity 200 is ensured to be sufficient, and the air concentration in the air dissolving water is ensured.

It will be appreciated that in the dissolved air tank 10 of the present invention, the outlet of the water inlet pipe 300 should be positioned higher than the inlet of the water outlet pipe 400. The reason is that when the liquid level of the dissolved air water in the dissolved air cavity 200 is not lower than the inlet of the water outlet pipe 400, the dissolved air water can be discharged out of the dissolved air tank 10 through the water outlet pipe 400, if the outlet of the water inlet pipe 300 is lower than the inlet of the water outlet pipe 400, before the liquid level of the dissolved air water needs to reach the inlet of the water outlet pipe 400, the outlet of the water inlet pipe 300 is submerged by the liquid level in the dissolved air cavity 200, the common water input into the dissolved air tank 10 by the water inlet pipe 300 cannot be fully mixed with the air in the dissolved air cavity 200, but is directly introduced into the dissolved air water, so that the air concentration in the dissolved air water is sharply reduced, and the micro bubble effect of the micro bubble water.

Among the prior art, dissolve the gas pitcher and do not establish inlet tube and outlet pipe, outside pipeline is direct to dissolving the interior intake of gas pitcher through the inlet port, dissolves the gas pitcher and directly goes out water to outside pipeline through the apopore, for avoiding above-mentioned condition, the apopore needs to be less than the inlet port setting, and the bottom of jar body is often located with the apopore to the current gas pitcher that dissolves, and the top of jar body is located to the inlet port. In summary, in the existing dissolved air tank, the arrangement of the water inlet hole and the water outlet hole is limited, thereby causing the pipeline arrangement outside the dissolved air tank to be too dispersed.

In the present invention, the water inlet pipe 300 of the air dissolving tank 10 has a portion extending into the air dissolving chamber 200, the arrangement positions of the water inlet hole and the water outlet hole are not limited, and even if the water inlet hole is arranged lower than the water outlet hole, the length of the water inlet pipe 300 extending into the air dissolving chamber 200 can be adjusted to make the outlet of the water inlet pipe 300 higher than the inlet of the water outlet pipe 400. So, can be close to the inlet opening with the apopore and set up to make inlet tube 300 and outlet pipe 400 can concentrate and arrange, also can concentrate with the outside pipeline that inlet tube 300 and outlet pipe 400 connect and arrange, thereby make this gas pitcher 10 of dissolving can the compact installation, avoid excessively invading to account for user's activity space, influence user's use and experience.

Further, in this embodiment, an air inlet is disposed on the tank wall 100, the air inlet pipe 700 is disposed on the air inlet and at least partially extends into the air dissolving cavity 200, and an outlet of the air inlet pipe 700 is disposed near an outlet of the water inlet pipe 300. It will be appreciated that the air supplied into the dissolved air chamber 200 by the air inlet pipe 700 is initially concentrated near the outlet of the air inlet pipe 700 and then takes some time to diffuse within the dissolved air tank 10. In this embodiment, the outlet of the air inlet pipe 700 is disposed near the outlet of the water inlet pipe 300, so that the common water input by the water inlet pipe 300 can directly reach the region with higher air concentration, which is beneficial to fully mixing with air, thereby improving the air concentration in the dissolved air water.

Further, in this embodiment, as shown in fig. 2, the portion of the water inlet pipe 300 extending into the air dissolving chamber 200 has a bent structure to guide the inlet water flow to a predetermined position in the air dissolving chamber 200. Thus, the direction of the water inlet pipe can be adjusted more flexibly, so that the outlet of the water inlet pipe can be arranged at a proper position, and the inlet water flow can be guided to the preset position in the air dissolving chamber 200. Of course, in other embodiments, the portion of the inlet pipe may be a straight pipe structure to avoid local loss of water flow at the bent pipe.

Without loss of generality, in the embodiment, as shown in fig. 2, the outlet of the water inlet pipe 300 faces and is arranged close to the tank wall 100, it can be understood that the water flow output by the outlet of the water inlet pipe 300 has a certain flow velocity, so that when the water flow reaches the tank wall 100 facing the outlet of the water inlet pipe, the water flow is sprayed in a scattered manner, which is equivalent to increasing the contact area between the water flow and the air in the air dissolving cavity 200, so that the water flow can sufficiently mix the air in the air dissolving cavity 200, and thus the air concentration in the air dissolving water output by the water outlet pipe 400 is increased. The higher the air concentration in the dissolved air water is, the better the bubble effect of the micro-bubble water output by the water end is.

In particular, the distance between the outlet of the inlet pipe 300 and the facing can wall 100 is 1mm-10 mm. On one hand, the closer the distance between the outlet of the water inlet pipe 300 and the tank wall 100 is, the more dispersedly the water flow sprayed from the outlet of the water inlet pipe 300 is sprayed to the periphery after reaching the tank wall 100, which is more favorable for the air to be dissolved in the water; on the other hand, the closer the distance between the outlet of the water inlet pipe 300 and the tank wall 100 is, the greater the resistance to the outgoing water flow, and the greater the influence on the water inflow rate at the outlet of the water inlet pipe 300. In this embodiment, the distance between the outlet of the water inlet pipe 300 and the tank wall 100 facing the outlet is 1mm-10mm, which not only can make the water flow have a good diffusion effect, but also does not have an excessive influence on the water inflow rate of the outlet of the water inlet pipe 300.

Further, in the present embodiment, as shown in fig. 2, a portion of the air inlet pipe 700 extending into the air dissolving chamber 200 has a bent structure to guide the air flow to a predetermined position in the air dissolving chamber 200. Therefore, the direction of the air inlet pipe can be flexibly adjusted to ensure that the outlet of the air inlet pipe 700 can be arranged close to the outlet of the water inlet pipe 300. Of course, in other embodiments, the portion of the air inlet pipe may also be a straight pipe structure to avoid local loss of the air flow at the bent pipe, and in addition, the position of the air inlet hole is adjusted to enable the outlet of the air inlet pipe 700 to be arranged close to the outlet of the water inlet pipe 300.

Further, in this embodiment, the inlet opening, the outlet opening and the inlet opening are disposed on the same side of the tank body. That is, as shown in fig. 1 and 4, the positions of the water inlet pipe 300, the water outlet pipe 400 and the air inlet pipe 700 connected with the outer side of the tank body wall 100 are on the same side, so that the water inlet pipe 300, the water outlet pipe 400 and the air inlet pipe 700 outside the dissolved air tank 10 can be more intensively arranged, and the pipeline arrangement outside the dissolved air tank 10 is more reasonable, so that the dissolved air tank 10 can be more compactly matched with other structures of a water heater.

Further, in this embodiment, as shown in fig. 2, the outlet of the inlet tube 300 is disposed toward and near the top of the can wall 100. That is, the water inlet pipe 300 inside the air dissolving chamber 200 is bent upward, so that the outlet of the water inlet pipe 300 is disposed at the top of the air dissolving chamber 200, and the emergent water flow of the water inlet pipe 300 can be sprayed on the top of the tank wall 100. On the one hand, the direction of the initial velocity of the emergent water flow deviates from the direction of the gravitational acceleration, and on the other hand, the emergent water flow begins to fall from the top of the air dissolving cavity 200, so that the distance and time of the emergent water flow mixing with the air in the air dissolving cavity 200 can be increased to the maximum extent, thereby effectively improving the air concentration in the air dissolving water, and the air dissolving tank 10 can continuously supply the air dissolving water with high air concentration. Of course, in other embodiments, it is also possible that the top of the air-dissolving chamber 200 is provided with a baffle 500, and the outlet of the water inlet pipe 300 is arranged towards and close to said baffle 500.

Further, in this embodiment, as shown in fig. 2, the water outlet pipe 400 at least partially extends into the air dissolving chamber 200, and the inlet of the water outlet pipe 400 is disposed near the bottom of the air dissolving chamber 200. Thus, the water outlet hole does not need to be arranged close to the bottom of the tank body, and the inlet of the water outlet pipe 400 can be ensured to be lower than the outlet of the water inlet pipe 300 by extending the part of the water outlet hole extending into the air dissolving cavity 200. In this embodiment, without loss of generality, the apopore is located the middle part position of dissolving gas pitcher 10, and inlet opening and inlet port and apopore are located same one side of the jar body to avoid the bottom trompil, thereby ensure the leakproofness of jar body wall 100 bottom, avoid dissolving gas pitcher 10 bottom and leaking. The inlet of the water outlet pipe 400 should be arranged as close to the bottom of the dissolved air cavity 200 as possible, so that the dissolved air water at a low liquid level can still be discharged out of the dissolved air tank 10 through the water outlet, but the inlet of the water outlet pipe 400 cannot be excessively close to the tank wall 100, so that the dissolved air water is prevented from being blocked by the tank wall 100 in the process of converging to the inlet of the water outlet pipe 400. Particularly, in the present embodiment, the distance between the inlet of the outlet pipe 400 and the tank wall 100 is 1mm to 10mm, so that the dissolved air water can be smoothly discharged out of the dissolved air chamber 200 through the outlet pipe 400. In other embodiments, the water outlet hole may be formed in the wall of the tank body at the bottom, and then the tank body is sealed to prevent water from leaking from the bottom of the dissolved air tank.

Further, in this embodiment, as shown in fig. 1 and fig. 4, a one-way valve 50 is disposed at a portion of the air inlet pipe 700 located outside the tank body, so that the air source is unidirectionally conducted to the air dissolving chamber 200, that is, air can only flow from the air source to the air dissolving tank 10, and thus, air in the air dissolving tank 10 can be prevented from flowing back to the air source through the air inlet pipe 700, an air supply effect of the air source is ensured, and thus, sufficient air in the air dissolving tank 10 is ensured.

Further, in this embodiment, as shown in fig. 3 and 4, a portion of the water inlet pipe 300 located outside the tank body is provided with a solenoid valve 60, and the solenoid valve 60 is used for conducting or blocking the water inlet flow path of the water inlet pipe 300. In order to avoid the interference between the air supply process of the air source and the water inlet process of the warm water, when the air source starts to supply air into the dissolved air tank 10, the electromagnetic valve 60 is actuated to block the water inlet flow path of the water inlet pipe 300 and stop water from entering the dissolved air tank 10; when the air supply stops supplying air into the dissolved air tank 10, the electromagnetic valve 60 is actuated to conduct the water inlet flow path of the water inlet pipe 300, and the water inlet into the dissolved air tank 10 is resumed. It can be understood that the dynamic pressure is too large when water enters, the air source cannot supplement air in the air tank 10, and when the air source does not supplement air in idle running, the noise is too large, and the energy waste is caused. In addition, since the solenoid valve 60 is opened when the water inlet pipe 300 is supplied with water into the air dissolving chamber 200 only when the user uses micro bubble water, the solenoid valve 60 may be set to be a normally closed solenoid valve 60 to reduce the amount of electricity consumed by the solenoid valve 60, thereby saving energy.

Further, in this embodiment, as shown in fig. 2, a partition plate is further disposed in the dissolved air chamber 200, and the partition plate is located between the outlet of the water inlet pipe 300 and the inlet of the water outlet pipe 400, and is used for intercepting the large bubbles flowing to the inlet of the water outlet pipe 400, so as to avoid mixing the large bubbles in the dissolved air flowing out of the water outlet pipe 400. It can be understood that when the water that possesses certain kinetic energy washed the liquid level interface in the jar, can produce a large amount of big bubbles, this part big bubble is not micro-nano bubble, and the air in the big bubble does not dissolve in aqueous, if the dissolved air aquatic of outlet pipe 400 output contains a large amount of big bubbles, not only can excessively consume the air in the dissolved air jar 10, and when the air in the big bubble was released at the rear end, the user can hear the big bubble sound of cracking of dazzling at the end of using water, user's use experience has greatly been influenced. In this embodiment, the baffle can play the effect of intercepting the big bubble, has not only reduced the consumption of the interior air of dissolved air tank 10, has also promoted the water experience of user at the water end.

Further, in the present embodiment, as shown in fig. 2, the partition comprises a first partition 610 extending downward from the top of the air dissolving chamber 200, and the first partition 610 is disposed near the outlet of the water inlet pipe 300. For convenience of description, the side closer to the water outlet pipe 400 is referred to as the left side, and the side closer to the water inlet pipe 300 is referred to as the right side. Because the first partition plate 610 blocks, scattered water flow can only fall into the accumulated water at the lower right corner of the air dissolving cavity 200, so that large bubbles can only be generated at the position, and because the water flow continuously falls at the position, the generated large bubbles can be basically broken by the water flow, even if a small part of large bubbles are remained, the large bubbles can rise and break when the large bubbles do not reach in time in the process of flowing to the inlet of the water outlet pipe 400 at the lower left corner of the air dissolving cavity 200 due to long distance, so that the output air dissolving water does not have the large bubbles.

Optionally, the partition plate further includes a second partition plate disposed near the water outlet pipe 400, and is configured to intercept large bubbles near the water outlet, so as to prevent the large bubbles from flowing out of the dissolved air tank 10 through the water outlet.

Further, in the present embodiment, as shown in fig. 2, the upper end of the first partition plate 610 is provided with an air hole 611. It can be understood that the first partition plate 610, while playing a role of intercepting large bubbles, also obstructs the air circulation of the air dissolving chamber 200 at the left and right sides thereof to some extent, and the air holes 611 formed on the first partition plate 610 can allow the air circulation at the left and right sides thereof. Specifically, when the air inlet pipe 700 supplies air into the air dissolving cavity 200 on the right side of the first partition plate 610, the air on the right side can be supplied to the left side through the air holes 611, so that more air can be supplied into the air dissolving cavity 200 by the air source; when the water flow entering the water inlet pipe 300 continuously dissolves the air in the air dissolving chamber 200 on the right side of the first partition plate 610, the air on the left side of the first partition plate 610 can be supplemented to the right side through the air holes 611, thereby ensuring that sufficient air is available for the water flow of the water inlet to dissolve.

In another embodiment of the present invention, as shown in fig. 5 to 7, the intake pipe 700 is connected to a portion of the water inlet pipe 300 located outside the tank body. In this embodiment, the tank wall 100 is not provided with an air inlet, the air inlet pipe 700 is connected to the water inlet pipe 300, and part of the pipelines of the water inlet pipe 300 are used for air supply. It should be noted that in the present embodiment, the air supply process and the water intake process of the dissolved air tank 10 are performed separately, so that even if the water intake process and the air intake process involve a common pipeline, the two processes are not affected. In addition, in the embodiment, the electromagnetic valve 60 should be disposed at a side of the connection between the air inlet pipe 700 and the water inlet pipe 300, which is far from the tank body, so as to ensure that the air inlet pipe 700 can also supplement air through the portion sharing the water inlet pipe 300 when the electromagnetic valve 60 blocks the water inlet flow path of the water inlet pipe 300.

Further, in this embodiment, as shown in fig. 6, the tank further includes a baffle 500 disposed at the top of the air dissolving chamber 200, and the outlet of the water inlet pipe 300 faces and is disposed near the baffle 500. Similarly, when the water flow reaches the baffle 500, the water flow is also sprayed in a scattered manner, the contact area between the water flow and the air in the air dissolving chamber 200 is increased, and the water flow can sufficiently mix the air in the air dissolving chamber 200, so that the air concentration in the air dissolving water output by the air dissolving tank 10 is increased.

Further, in this embodiment, the baffle 500 is disposed at the top of the air dissolving chamber 200, and the outlet of the water inlet pipe 300 is disposed toward and close to the baffle 500, so that when the water reaches the baffle 500 disposed at the top of the air dissolving chamber 200, the water will be sprayed in a scattered manner at the top of the air dissolving chamber 200, and thus, the scattered water can be sufficiently mixed with the air in a sufficient time and space, and the air dissolving tank 10 can continuously supply the air-dissolved water with high air concentration from the water outlet to the downstream end. Of course, in other embodiments, the baffle 500 may not be provided in the air dissolving tank 10, and the water inlet pipe 300 sprays water flow toward the top wall of the tank wall 100, so that the water flow has enough space and time to dissolve air.

Further, in this embodiment, as shown in fig. 6, the baffle 500 is vertically disposed at the top of the air dissolving cavity 200, as shown in the figure, the water inlet pipe 300 passes through the sidewall of the upper portion of the air dissolving tank 10 to reach the top of the air dissolving cavity 200, so that the outlet of the water inlet pipe 300 can spray water toward the baffle 500 at the top of the air dissolving cavity 200, and thus, the water inlet pipe 300 does not need to be bent, thereby avoiding local loss of water at the bent pipe, and the flow rate of the emergent water at the outlet of the water inlet pipe 300 can be further increased, so that when the water inlet pipe reaches the baffle 500, more divergent scattered water flow can be generated, and the water flow can be further mixed with the air in the air dissolving cavity. Of course, in other embodiments of the vertically arranged gas dissolving tank 10, the baffle 500 may be transversely disposed on the top of the gas dissolving tank 200, and the water inlet pipe 300 penetrates through the top wall of the gas dissolving tank 10, so that the outlet of the water inlet pipe 300 is disposed toward the baffle 500, and thus, the water inlet pipe 300 does not need to be additionally provided with an elbow structure, and the water flow emitted from the outlet of the water inlet pipe 300 does not generate flow rate loss.

Further, in this embodiment, as shown in fig. 6, the surface of the baffle 500 is provided with a rib 510 to enhance the structural strength of the baffle 500. It can be understood that, because the water flow outgoing from the outlet of the water inlet pipe 300 has a certain flow velocity, when it sprays the baffle 500, a certain impact force is generated on the baffle 500, and the reinforcing ribs 510 on the surface of the baffle 500 can enhance the structural strength of the baffle 500, so as to improve the bearing capacity of the baffle 500 on the water flow impact and avoid the damage of the baffle 500 under the impact action of the water flow.

Further, in this embodiment, the distance between the outlet of the water inlet pipe 300 and the baffle 500 facing thereto is 1mm-10mm, so that the water flow can be diffused well without causing an excessive influence on the water inflow rate at the outlet of the water inlet pipe 300.

Further, in this embodiment, as shown in fig. 7, the partition plate includes a second partition plate 620 disposed near the inlet of the water outlet pipe 400, the second partition plate 620 is a ring plate structure, and the second partition plate 620 is sleeved outside the water outlet pipe 400. The second partition 620 can break the big bubbles colliding with it to make the air overflow, a part of the overflowed air can be dissolved in water, and a part of the overflowed air rises to be supplemented into the air in the air dissolving cavity 200, so as to avoid unnecessary consumption of the air in the air dissolving cavity 200, and simultaneously avoid the big bubbles breaking at the water using end and generating harsh breaking sound to influence the water using experience of users.

Further, in this embodiment, as shown in fig. 3 and 4, the water heater further includes:

a cold water inlet pipe 30 and a hot water outlet pipe 40;

an inner container 70 connected to a water source through the cold water inlet pipe 30;

a mixing valve 20 connected to a water source through the cold water inlet pipe 30 and connected to the inner container 70 through the hot water outlet pipe 40; and

the bubble generator is connected to the tank body through the water outlet pipe 400;

the water mixing valve 20 is used for mixing hot water in the hot water outlet pipe 40 with cold water in the cold water inlet pipe 30 to form warm water, and the warm water flows into the air dissolving cavity 200 through the water inlet pipe 300 and then is mixed with air, so that the water outlet pipe 400 outputs air dissolving water, and the bubble generator is made into micro-bubble water by using the air dissolving water.

Without loss of generality, in the embodiment, the water heater is an electric water heater, the cold water inlet pipe 30 has an inlet end connected to a water source, one outlet end of the cold water inlet pipe 30 is connected to the inner container 70 to provide cold water to the inner container 70, and in addition, the cold water inlet pipe 30 also has the other outlet end connected to the mixing valve 20;

the hot water outlet pipe 40 is connected between the inner container 70 and the water mixing valve 20 to output hot water generated by heating the inner container 70 to the water mixing valve 20;

the water mixing valve 20 is also communicated with the water inlet pipe 300 of the dissolved air tank 10, water is fed into the water mixing valve 20 through the cold water inlet pipe 30 and the hot water outlet pipe 40, and water is discharged from the water inlet pipe 300, and the water mixing valve 20 is used for mixing hot water in the hot water outlet pipe 40 with cold water in the cold water inlet pipe 30, namely mixing hot water generated by the water heater inner container 70 with cold water from a water source, so as to obtain warm water and enabling the warm water to flow into the dissolved air cavity 200;

because the air is filled in the air dissolving cavity 200, warm water enters the air dissolving cavity 200, and a certain amount of air is dissolved in the warm water to form air-dissolved water, so that the water outlet pipe 400 can output the air-dissolved water;

and a bubble generator is arranged between the dissolved air tank 10 and the water using end of the user and is used for releasing the air dissolved in the dissolved air to form micro-bubble water, and the micro-bubble water is output through the water using end of the user to be used for bathing by the user.

In the prior art, in the water heater with the microbubble bathing function, the air dissolving process is prior to the water mixing process, that is, the hot water with dissolved air is introduced into the water mixing valve 20, and then the warm water with dissolved air is output through the water mixing valve 20. However, the solubility of air in water decreases with increasing temperature, and the dissolution effect of hot water on air is poor; furthermore, after the mixing process of the hot water and the cold water, the air solubility in the obtained warm water is further decreased. Therefore, in this type of water heater, the air content in the final warm water is very low, which results in insignificant micro-bubble effect of the micro-bubble water finally delivered from the water end.

In the invention, the water mixing process of the water heater is prior to the gas dissolving process, firstly, the water mixing valve 20 mixes the hot water generated by the inner container 70 of the water heater with the cold water from a water source and outputs warm water; then, warm water enters the air dissolving cavity 200, and the air in the air dissolving cavity 200 is dissolved in the warm water to obtain the water dissolved with air. Because the solubility of the air in the warm water is higher than that of the air in the hot water, and the water outlet pipe 400 is communicated with the bubble generator, the air solubility of the air-dissolved water cannot be changed before the micro-bubble water is formed, so that the air concentration of the air-dissolved water in the water heater is higher, and the micro-bubble effect of the obtained micro-bubble water is more obvious.

Of course, in other embodiments, the water heater may also be a gas water heater, in which a cold water inlet pipe 30 and a hot water outlet pipe 40 are connected to the gas water heater, cold water is input into the gas water heater from the cold water inlet pipe 30, and the gas water heater can heat the cold water and deliver the generated hot water to the mixing valve 20 through the hot water outlet pipe 40.

So, the user only needs to set for the temperature, the warm water of this temperature can be continuously and constantly exported to the valve 20 that mixes water with the constant temperature, the loaded down with trivial details of manual regulation temperature has been avoided, and simultaneously, the temperature constancy of the warm water that lets in dissolved air jar 10 can be guaranteed to the valve 20 that mixes water with the constant temperature, under the prerequisite that the air is sufficient, the solubility of warm water to the air also will be invariable, therefore, the air concentration in the dissolved air aquatic of dissolved air jar 10 output can be maintained in the certain limit, in order to guarantee to keep exporting little bubble water of microbubble effect basic unanimity with the water end, thereby further promote user's bathing experience.

Further, in this embodiment, the bubble generator includes a venturi tube. Venturi can comparatively simply separate out the air that dissolves in the rivers to make the microbubble, so, needn't design unnecessary water pump, heating device or control flap etc. greatly simplified bubble generator's structure, reduced manufacturing cost, and venturi does not have extra requirement to the mode of intaking, can produce a large amount of microbubbles comparatively easily.
