The present invention proposes a dissolved air tank 10.
In one 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 dissolved air cavity 200;
a water outlet pipe 400 arranged at the water outlet hole; and
one end of the air inlet pipe 700 is communicated with an air source, and the other end is communicated with the dissolved air cavity 200.
In the present invention, the common water in the external pipeline enters the dissolved air chamber 200 through the water inlet pipe 300, and is fully mixed with the air in the dissolved air chamber 200 to form dissolved air water, and the dissolved air water is discharged out of the dissolved air chamber 200 through the water outlet pipe 400, so that the dissolved air water flows to other devices at the rear end through the external pipeline, 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 dissolved air cavity 200, so that the air source can convey air in the dissolved air cavity 200, the air in the dissolved air cavity 200 is ensured to be sufficient, and the air concentration in the dissolved air 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 disposed higher than the inlet of the water outlet pipe 400. The reason is that when the liquid level of the dissolved air in the dissolved air chamber 200 is not lower than the inlet of the water outlet pipe 400, the dissolved air 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 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 chamber 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 chamber 200, but is directly connected into the dissolved air water, so that the air concentration in the dissolved air water is reduced sharply, and the micro-bubble effect of micro-bubble water output by the water end is greatly affected.
In the prior art, the water inlet pipe and the water outlet pipe are not arranged on the water dissolving tank, the external pipeline directly enters water into the water dissolving tank through the water inlet hole, the water dissolving tank directly discharges water to the external pipeline through the water outlet hole, the water outlet hole is required to be lower than the water inlet hole for avoiding the above situation, the water outlet hole is often arranged at the bottom of the tank body, and the water inlet hole is arranged at the top of the tank body. In general, in the existing dissolved air tanks, the arrangement of the water inlet holes and the water outlet holes is limited, thereby causing the arrangement of the pipelines outside the dissolved air tanks to be too dispersed.
In the present invention, the water inlet pipe 300 of the dissolved air tank 10 has a portion penetrating into the dissolved air chamber 200, the arrangement position of the water inlet hole and the water outlet hole is not limited, and even if the water inlet hole is lower than the water outlet hole, the outlet of the water inlet pipe 300 is higher than the inlet of the water outlet pipe 400 by adjusting the length of the water inlet pipe 300 penetrating into the dissolved air chamber 200. So, can be close to the setting with inlet opening and apopore to make inlet tube 300 and outlet pipe 400 can concentrate the arrangement, the outside pipeline that meets with inlet tube 300 and outlet pipe 400 also can concentrate the arrangement, thereby make this dissolved air tank 10 can compact installation, avoid excessively encroaching on user's activity space, influence user's use experience.
Further, in this embodiment, an air inlet is provided on the tank wall 100, the air inlet pipe 700 is provided on the air inlet and extends into the solution chamber 200 at least partially, and the outlet of the air inlet pipe 700 is disposed near the outlet of the water inlet pipe 300. It will be appreciated that the air supplied into the dissolved air chamber 200 by the air intake pipe 700 is initially concentrated near the outlet of the air intake pipe 700, and then it takes a certain time to diffuse in the dissolved air tank 10. In this embodiment, the outlet of the air inlet pipe 700 is close to the outlet of the water inlet pipe 300, so that the normal water input by the water inlet pipe 300 can directly reach the area 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, a portion of the water inlet pipe 300 extending into the solution chamber 200 has a bent structure to guide the inflow water to a predetermined position in the solution chamber 200. In this way, the trend of the water inlet pipe can be more flexibly adjusted, so that the outlet of the water inlet pipe can be arranged at a proper position, and the inflow water flow can be guided to a preset position in the dissolving cavity 200. Of course, in other embodiments, the water inlet pipe can be of a straight pipe structure, so as to avoid local loss of water flow at the bent pipe.
In this embodiment, as shown in fig. 2, the outlet of the water inlet pipe 300 faces towards and is close to the tank wall 100, it can be understood that the water flow output from the outlet of the water inlet pipe 300 has a certain flow velocity, so when the water flow reaches the tank wall 100 facing towards the water flow, 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 dissolved air chamber 200, so that the water flow can be fully mixed with the air in the dissolved air chamber 200, and the air concentration in the dissolved air water output from the water outlet pipe 400 is improved. The higher the air concentration in the dissolved air water is, the better the air bubble effect of the micro air bubble water output by the water end is.
In particular, the distance between the outlet of the inlet pipe 300 and the tank wall 100 facing it is 1mm-10mm. On the one hand, the closer the distance between the outlet of the water inlet pipe 300 and the towards the tank wall 100 is, the more the water flow sprayed from the outlet of the water inlet pipe 300 will be dispersed around after reaching the tank wall 100, which is more beneficial for the dissolution of air in water; on the other hand, the closer the distance between the outlet of the inlet pipe 300 and the facing tank wall 100, the greater the resistance to the exiting water flow, and the greater the influence on the inlet water flow rate at the outlet of the inlet pipe 300. In this embodiment, the distance between the outlet of the water inlet pipe 300 and the facing tank wall 100 is 1mm-10mm, so that the water flow has a good diverging effect, and the water inflow of the outlet of the water inlet pipe 300 is not excessively affected.
Further, in this embodiment, as shown in fig. 2, a portion of the air inlet pipe 700 extending into the air dissolving cavity 200 has a bent structure to guide the air flow to a predetermined position in the air dissolving cavity 200. In this way, 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 air inlet pipe may be a straight pipe structure to avoid local loss of air flow at the bent pipe, and the position of the air inlet hole is adjusted to enable the outlet of the air inlet pipe 700 to be close to the outlet of the water inlet pipe 300.
Further, in this embodiment, the water inlet hole, the water outlet hole and the air inlet hole are disposed on the same side of the tank body. That is, as shown in fig. 1 and 4, the positions where the water inlet pipe 300, the water outlet pipe 400 and the air inlet pipe 700 are connected to the outside 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 the water heater.
Further, in this embodiment, as shown in fig. 2, the outlet of the water inlet pipe 300 is disposed toward and near the top of the tank wall 100. That is, the water inlet pipe 300 inside the dissolution chamber 200 is bent upward so that the outlet of the water inlet pipe 300 is provided at the top of the dissolution chamber 200, and the outgoing water flow of the water inlet pipe 300 can be sprayed at 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, on the other hand, the emergent water flow starts to fall from the top of the dissolved air cavity 200, so that the mixing distance and time of the emergent water flow and the air in the dissolved air cavity 200 can be increased to the greatest extent, the air concentration in the dissolved air water can be effectively improved, and the dissolved air tank 10 can continuously supply the dissolved air water with high air concentration. Of course, in other embodiments, a baffle 500 may be disposed at the top of the solution chamber 200, and the outlet of the water inlet pipe 300 may be disposed toward and near the baffle 500.
Further, in this embodiment, as shown in fig. 2, the water outlet pipe 400 extends at least partially into the solution chamber 200, and the inlet of the water outlet pipe 400 is disposed near the bottom of the solution chamber 200. In this way, the water outlet hole may not be disposed near the bottom of the tank, and by extending the portion thereof extending into the dissolution chamber 200, it is ensured that the inlet of the water outlet pipe 400 is lower than the outlet of the water inlet pipe 300. In this embodiment, without losing generality, the water outlet is arranged in the middle of the dissolved air tank 10, and the water inlet hole are arranged on the same side of the tank body as the water outlet, so as to avoid bottom opening, thereby ensuring the tightness of the bottom of the tank body wall 100 and avoiding water leakage at the bottom of the dissolved air tank 10. The inlet of the water outlet pipe 400 should be disposed as close to the bottom of the dissolved air chamber 200 as possible, so that the low-level dissolved air water can still be discharged out of the dissolved air tank 10 through the water outlet, but the inlet of the water outlet pipe 400 may not be too close to the tank body wall 100, so as to avoid the blockage of the dissolved air water by the tank body wall 100 in the process of converging towards the inlet of the water outlet pipe 400. In particular, in the present embodiment, the distance between the inlet of the water outlet pipe 400 and the tank wall 100 is 1mm to 10mm so that the dissolved air can be smoothly discharged out of the dissolved air chamber 200 through the water outlet pipe 400. Of course, in other embodiments, the water outlet may be formed in the bottom wall of the tank, and then sealed to avoid water leakage from the bottom of the tank.
Further, in this embodiment, as shown in fig. 1 and fig. 4, the portion of the air inlet pipe 700 located outside the tank body is provided with a one-way valve 50, so that the air source is unidirectional conducted to the air dissolving chamber 200, that is, air can only flow from the air source to the air dissolving tank 10, so that the air in the air dissolving tank 10 can be prevented from flowing back to the air source through the air inlet pipe 700, the air supplementing effect of the air source is ensured, and 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 to conduct or block the water inlet flow path of the water inlet pipe 300. In order to avoid interference between the air supply process and the warm water inlet process, when the air supply starts to supply air into the dissolved air tank 10, the electromagnetic valve 60 is made to act so as to block the water inlet flow path of the water inlet pipe 300 and stop water inlet into the dissolved air tank 10; when the air supply stops supplying air into the dissolved air tank 10, the electromagnetic valve 60 is operated again to conduct the water inlet flow path of the water inlet pipe 300, and water inlet into the dissolved air tank 10 is restored. It can be understood that, because the dynamic pressure is too large during water intake, the air source cannot supplement air to the dissolved air tank 10, and when the air source idles and does not supplement air, noise is too large, and energy waste is caused, so that the air supplementing process and the water intake process are separately performed, the air supplementing process of the dissolved air tank 10 is not interfered by the water intake process, and interference of air source noise and energy waste can be reduced. In addition, since the solenoid valve 60 is opened only when the user uses the micro bubble water when the water inlet pipe 300 is to be filled into the dissolved air chamber 200, the solenoid valve 60 may be provided as a normally closed solenoid valve 60 to reduce the amount of electricity consumed by the solenoid valve 60, thereby playing a role of saving energy.
Further, in this embodiment, as shown in fig. 2, a partition plate is further disposed in the solution 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 large bubbles flowing to the inlet of the water outlet pipe 400, so as to avoid mixing large bubbles in the solution water flowing out from the water outlet pipe 400. It can be understood that when water with a certain kinetic energy is flushed to the liquid level interface in the tank, a large amount of large bubbles are generated, the large bubbles are not micro-nano bubbles, and the air in the large bubbles is not dissolved in the water, if the air-dissolving water output by the water outlet pipe 400 contains a large amount of large bubbles, the air in the air-dissolving tank 10 can be excessively consumed, and when the air in the large bubbles is released at the rear end, a user can hear the harsh large bubble cracking sound at the water use end, so that the use experience of the user is greatly influenced. In this embodiment, the partition plate can play a role in intercepting large bubbles, so that not only is the consumption of air in the dissolved air tank 10 reduced, but also the water use experience of a user at the water use end is improved.
Further, in the present embodiment, as shown in fig. 2, the partition includes a first partition 610 extending downward from the top of the dissolution 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 610 blocks the scattered water flow, the large bubbles can be generated only at the right lower corner of the dissolved air chamber 200, 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 the large bubbles remain, the large bubbles can rise and break up before reaching due to the longer distance in the process of flowing to the inlet of the water outlet pipe 400 positioned at the left lower corner of the dissolved air chamber 200, so that the output dissolved air water does not exist.
Optionally, the partition plate further includes a second partition plate disposed near the water outlet pipe 400, for intercepting large bubbles near the water outlet, and preventing 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 610 is provided with a ventilation hole 611. It can be understood that the first partition 610 plays a role of intercepting large bubbles, and also blocks the air circulation of the solution chamber 200 on the left and right sides thereof to some extent, and the ventilation holes 611 provided on the first partition 610 allow the air on the left and right sides thereof to circulate. Specifically, when the air inlet pipe 700 supplements air into the right side dissolved air chamber 200 of the first partition 610, the air on the right side can be supplemented to the left side through the air holes 611, so that the air source can supplement more air into the dissolved air chamber 200; while the water flow entering through the water inlet pipe 300 continuously dissolves the air in the right side dissolving air chamber 200 of the first partition 610, the air at the left side of the first partition 610 can be supplemented to the right side through the air holes 611, thereby ensuring that there is sufficient air for the water flow at the water inlet to dissolve.
In another embodiment of the present invention, as shown in fig. 5 to 7, the air inlet 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 pipeline sharing the water inlet pipe 300 is used for air supply. In this embodiment, the air supply process of the dissolved air tank 10 is performed separately from the water intake process, and therefore, even if the water intake process and the air intake process involve a common pipe, the two processes are not affected. In addition, in the present embodiment, the electromagnetic valve 60 should be disposed at a side of the connection portion of the air inlet pipe 700 and the water inlet pipe 300 away from the tank, 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 solution chamber 200, and the outlet of the water inlet pipe 300 is disposed toward and near the baffle 500. Similarly, when the water flow reaches the baffle 500, the water flow is scattered and sprayed, the contact area between the water flow and the air in the dissolved air chamber 200 is increased, and the water flow can be fully mixed with the air in the dissolved air chamber 200, so that the air concentration in the dissolved air water output by the dissolved air tank 10 is improved.
Further, in this embodiment, the baffle 500 is disposed at the top of the dissolution chamber 200, and the outlet of the water inlet pipe 300 is disposed towards and near the baffle 500, so that when the water reaches the baffle 500 disposed at the top of the dissolution chamber 200, the water will be sprayed at the top of the dissolution chamber 200, and thus, the dispersed water will have enough time and space to be fully mixed with air, so that the dissolution tank 10 can continuously supply the dissolution 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 tank 10, and the water inlet pipe 300 may spray water toward the top wall of the tank wall 100, so that the water may have 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 solution chamber 200, as shown in the fig. 6, the water inlet pipe 300 passes through the side wall of the upper portion of the solution tank 10 to reach the top of the solution chamber 200, so that the outlet of the water inlet pipe 300 can spray water towards the baffle 500 at the top of the solution chamber 200, thus, the water inlet pipe 300 does not need to be bent, local loss of water at the bent pipe can be avoided, the flow rate of the outgoing water flow at the outlet of the water inlet pipe 300 can be further increased, and therefore, when the outgoing water flow reaches the baffle 500, more divergent scattered water flow can be generated, and the water flow and the air in the solution chamber 200 can be further mixed sufficiently. Of course, in other embodiments of the vertical tank 10, the baffle 500 may be transversely disposed at the top of the tank 200, and the water inlet pipe 300 passes through the top wall of the tank 10, so that the outlet of the water inlet pipe 300 is disposed towards the baffle 500, and thus, the water inlet pipe 300 does not need to be additionally provided with a bent pipe structure, and the water flow exiting from the outlet of the water inlet pipe 300 does not generate flow velocity loss.
Further, in this embodiment, as shown in fig. 6, the surface of the baffle 500 is provided with reinforcing ribs 510 to strengthen the structural strength of the baffle 500. It can be appreciated that, since the water flow exiting from the outlet of the water inlet pipe 300 has a certain flow velocity, when the water flow is sprayed to 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 impact of the water flow and avoid the baffle 500 from being damaged 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 the outlet is 1mm-10mm, so that the water flow has a good diverging effect, and the inflow of the outlet of the water inlet pipe 300 is not excessively affected.
Further, in this embodiment, as shown in fig. 7, the partition includes a second partition 620 disposed near the inlet of the water outlet pipe 400, the second partition 620 has a ring plate structure, and the second partition 620 is sleeved outside the water outlet pipe 400. The second separator 620 may break up the large bubbles impinging thereon, so that the air therein overflows, a part of the overflowed air may be dissolved in water, and a part of the overflowed air rises to be supplemented into the air in the dissolved air chamber 200, so as to avoid unnecessary consumption of the air in the dissolved air chamber 200, and also avoid breaking up the large bubbles at the water end and emitting harsh breaking sound, thereby affecting the water use experience of the user.
The invention also provides a water heater.
In an embodiment of the present invention, as shown in fig. 3 and fig. 4, the water heater includes the aforementioned dissolved air tank 10, and the specific structure of the dissolved air tank 10 refers to the foregoing embodiment, and since the water heater adopts all the technical solutions of all the foregoing embodiments, at least has all the beneficial effects brought by the technical solutions of the foregoing embodiments, which are not described in detail herein.
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;
the water mixing valve 20 is connected with a water source through the cold water inlet pipe 30 and is connected with 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 mixing valve 20 is used for mixing the hot water in the hot water outlet pipe 40 with the cold water in the cold water inlet pipe 30 to form warm water, and the warm water flows into the dissolved air chamber 200 through the water inlet pipe 300 and then is mixed with air, so that the water outlet pipe 400 outputs the dissolved air water, and the bubble generator utilizes the dissolved air water to prepare micro-bubble water.
In this embodiment, the water heater is an electric water heater, the cold water inlet pipe 30 has a water inlet end connected to a water source, and a water 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 has another water outlet end connected to the water mixing valve 20;
the hot water outlet pipe 40 is connected between the inner container 70 and the water mixing valve 20, so as to output hot water generated by heating the inner container 70 to the water mixing valve 20;

because the air is filled in the air dissolving cavity 200, warm water enters the air dissolving cavity 200, a certain amount of air can be dissolved in the air dissolving cavity to form air dissolving water, and the water outlet pipe 400 can output the air dissolving water;
between the dissolved air tank 10 and the water end of the user, there is also provided a bubble generator for releasing the air dissolved in the dissolved air water to form micro bubble water, and outputting the micro bubble water through the water end of the user for the user to bath.
In the prior art, in the water heater having the micro bubble bath function, the air dissolving process is performed before 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 outputted 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 hot water and cold water, the air solubility in the obtained warm water will be further reduced. Therefore, in this type of water heater, the air content in the final warm water is extremely small, and thus the micro-bubble effect of the micro-bubble water finally output by the water end is not obvious.
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 water heater liner 70 with the cold water from the water source, and outputs warm water; then, warm water enters the dissolved air chamber 200, and air in the dissolved air chamber 200 is dissolved in the warm water to obtain dissolved air water. Because the solubility of air in warm water is higher than that of the air in 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 air-dissolved water forms micro-bubble water, so that the air concentration of the air-dissolved water is higher, and the micro-bubble effect of the obtained micro-bubble water is more obvious in the water heater.
Of course, in other embodiments, the water heater may be a gas water heater, where 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 may heat the cold water and deliver the generated hot water to the mixing valve 20 through the hot water outlet pipe 40.

Therefore, the user only needs to set the temperature, the constant-temperature water mixing valve 20 can continuously and constantly output warm water with the temperature, the trouble of manually adjusting the water temperature is avoided, meanwhile, the constant-temperature water mixing valve 20 can ensure that the temperature of the warm water introduced into the dissolved air tank 10 is constant, and the solubility of the warm water to air is constant on the premise that the air is sufficient, so that the air concentration in the dissolved air water output by the dissolved air tank 10 can be maintained in a certain range, the water end is ensured to continuously output micro-bubble water with basically consistent micro-bubble effect, and the bathing experience of the user is further improved.
Further, in the present embodiment, the bubble generator includes a venturi tube. The venturi tube can separate out the air dissolved in the water flow more simply and make micro-bubbles, so that redundant water pumps, heating devices or control valves and the like do not need to be designed, the structure of the bubble generator is greatly simplified, the production cost is reduced, the venturi tube has no additional requirement on the water inlet mode, and a large number of micro-bubbles can be generated more easily.
Further, in this embodiment, the bubble generator may be a bubble generating faucet or a bubble generating shower, so that a user may use micro-bubble water at different water usage ends; therefore, a user can wash hands by utilizing the micro-bubble water output by the bubble generation faucet, and can also use the micro-bubble water output by the bubble generation shower head for bathing.
