Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a microbubble generator and its gas water heater. Background Technology

[0002] Nano-microbubble water possesses bactericidal and deep-cleaning properties, and does not produce substances harmful to the human body, making it a new trend in the hot water supply equipment industry. Currently, microbubble water heaters on the market typically have a dissolved air tank installed in the internal water circuit. When the microbubble function is running, water pressure causes air from the dissolved air tank to dissolve into the water, forming microbubble water with a gas-liquid mixture ratio of approximately 1% to 3%. Based on a 1L dissolved air tank, this translates to an output of only about 100L of microbubble water. Furthermore, once the air in the dissolved air tank is depleted, it needs to be refilled using a high-pressure air pump. However, high-pressure air pumps are expensive, occupy significant installation space, and generate considerable noise during operation. Summary of the Invention

[0028] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0029] refer to Figure 1 This embodiment provides a microbubble generator, including a dissolved gas tank 1 and at least one electrolysis component 2. The dissolved gas tank 1 has a partition (not shown in the figure) that divides the interior of the dissolved gas tank 1 into a first cavity 121 and a second cavity 122. The partition has multiple diversion holes 101 that connect to the first cavity 121 and the second cavity 122 respectively. The dissolved gas tank 1 has an inlet 102 connecting to the first cavity 121 and an outlet 103 connecting to the second cavity 122. The inlet 102 is used to connect to the tap water supply pipe at the front end of a water heater, and the outlet 103 is used to connect to the user's water point. At least one electrolysis component 2 is connected to the dissolved gas tank 1, and a portion of at least one electrolysis component 2 is located within the second cavity 122. The electrolysis component 2 is used to electrolyze the water stored in the dissolved gas tank 1 to generate gas, thereby pre-filling the dissolved gas tank 1 with gas.

[0030] like Figure 6 As shown, when the user is using water but has not turned on the tap, if the water level in the dissolved air tank 1 is higher than the minimum operating point of the electrolysis component 2, the water will be electrolyzed by the electrolysis component 2 to produce hydrogen and oxygen. The oxygen and hydrogen produced by the electrolysis will rise and accumulate at the top of the dissolved air tank 1, slowly displacing the water inside. At this time, since no water is discharged from the outlet 103 of the dissolved air tank 1, the water in the dissolved air tank 1 will be discharged back to the tap water supply pipe at the front end of the water heater from the inlet 101. When the water level in the dissolved air tank 1 is lower than the minimum operating point of the electrolysis component 2, the electrolysis component 2 will automatically stop electrolysis and produce gas, at which point the dissolved air tank 1 will be filled with a hydrogen-oxygen mixture.

[0031] like Figure 7As shown, after the dissolved air tank 1 completes electrolytic filling, when the user uses hot water at the water point, tap water flows into the first chamber 121 from the inlet 102 of the dissolved air tank 1, flows through the diversion hole 101 of the partition and is dispersed and sprayed out, forming a sprinkler-like spray that fully mixes with the hydrogen-oxygen mixture inside the dissolved air tank 1, thereby forming microbubble water with a gas-liquid mixing ratio of approximately 1% to 3%. This water then flows from the outlet 103 of the dissolved air tank 1 to the water point, meeting the user's requirement for microbubble water. As tap water continues to flow into the dissolved air tank 1, when the water level in the dissolved air tank 1 is higher than the lowest operating point of the electrolysis component 2, the electrolysis component 2 performs electrolytic gas generation to ensure a continuous output of microbubble water during the water usage process. It is evident that in the electrolytic gas generation process, since there is no need for a high-pressure air pump, water pump, or liquid level sensor, the filling process does not generate noise, resulting in low cost and saving internal installation space.

[0032] Specifically, the first cavity 121 is located above the second cavity 122 (e.g., Figure 1 (As shown in either 3-5), in this case, the first cavity 121 and the second cavity 122 are arranged vertically. Of course, the first cavity 121 can also be designed to be located inside the upper part of the second cavity 121 (e.g., Figure 2 As shown), the first cavity 121 is surrounded by the second cavity 122. The inlet 102 and the outlet 103 are both located at the bottom of the dissolved air tank 1. Of course, the inlet 102 and / or the outlet 103 can also be designed at the lower end of the side wall of the dissolved air tank 1.

[0033] In this embodiment, a guide pipe 13 is provided in the second cavity 122, and the inlet 102 is connected to the first cavity 121 through the guide pipe 13, so as to facilitate the flow of tap water flowing in from the inlet 102 into the first cavity. Furthermore, a plurality of drain holes 131 are provided at intervals at the lower end of the guide pipe 13 and connected to the second cavity 122, so that when the user does not turn on the water and the electrolysis component 2 electrolyzes the stored water to produce gas, the stored water in the second cavity 122 can be drained back to the tap water supply pipeline at the front end of the water heater through the drain holes 131 and the inlet 102 of the guide pipe 13 in sequence, so as to facilitate automatic drainage until the electrolysis component 2 automatically stops electrolyzing and producing gas. At this time, the dissolved gas tank 1 will be filled with hydrogen-oxygen mixed gas.

[0034] refer to Figure 5 Specifically, in other embodiments, a drain outlet 14 communicating with the second chamber 122 can be provided at the bottom of the dissolved air tank 1. A switch valve (not shown in the figure) for opening or closing the drain outlet 14 is provided at the drain outlet 14. The outlet of the drain outlet 14 can be connected to a sewer, a water inlet 102, or a tap water supply pipe at the front end of the water heater. Due to the presence of the drain outlet 14 and the switch valve, the drain hole 131 on the guide pipe 13 can be omitted (e.g., ...). Figure 5As shown), of course, the guide pipe 13 and the drain hole 131 on the flow pipe 13 can be omitted. Correspondingly, the water inlet 102 can be designed on the top or upper side wall of the dissolved gas tank 1.

[0035] refer to Figure 1-5 The dissolved air tank 1 is made of corrosion-resistant metal such as stainless steel or high-strength plastic. The volume of the first chamber 121 is smaller than that of the second chamber 122, and the volume of the second chamber 122 is greater than 500mL to meet the user's requirements for microbubble water.

[0036] Specifically, the specific structure of the partition includes, but is not limited to, any of the following:

[0037] The first type, reference Figure 1 The partition is a partition plate 111, which is horizontally disposed inside the dissolved gas tank 1 and its outer periphery is fixedly connected to the dissolved gas tank 1. The partition plate 111 divides the interior of the dissolved gas tank 1 into a first cavity 121 and a second cavity 122 arranged vertically. A plurality of diversion holes 101 are provided on the partition plate 111 at intervals. Specifically, the partition plate 111 and the dissolved gas tank 1 can be independent components or integrally formed components; the upper and lower ends of the guide pipe 13 are integrally formed with the partition plate 111 and the dissolved gas tank 1, respectively, or the upper and lower ends of the guide pipe 13 are detachably connected with the partition plate 111 and the dissolved gas tank 1, respectively.

[0038] The second option is to refer to... Figure 2 The dividing part is a dividing cup 112, which is disposed inside the dissolved gas tank 1 and its top is fixedly connected to the top of the dissolved gas tank 1. The dividing cup 112 divides the interior of the dissolved gas tank 1 into a first cavity 121 and a second cavity 122. The first cavity 121 is located at the upper end of the interior of the second cavity 122. Multiple diversion holes 101 are provided at intervals on the side wall of the dividing cup 112. Specifically, the dividing cup 112 and the dissolved gas tank 1 can be integrally formed components, and the upper and lower ends of the guide pipe 13 are integrally formed with the dividing cup 112 and the dissolved gas tank 1, respectively.

[0039] Specifically, the arrangement of the electrolysis unit 2 includes, but is not limited to, any of the following:

[0040] The first type, see [link / reference] Figure 1-2 The electrolysis assembly 2 includes two electrodes 21 arranged side-by-side at intervals. Both electrodes 21 are horizontally positioned within the second cavity 122, with their fixed ends connected to the side wall of the dissolved gas tank 1. At this time, portions of both electrodes 21 are located within the second cavity 122. When the water level in the dissolved gas tank 1 is higher than the minimum operating point of the electrolysis assembly 2, the two electrodes 21 conduct electricity under the influence of the water, electrolyzing the water in the dissolved gas tank 1 to produce gas. Conversely, when the water level in the dissolved gas tank 1 is lower than the minimum operating point of the electrolysis assembly 2, the two electrodes 21 cannot conduct electricity, and the electrolysis assembly 2 automatically stops electrolyzing to produce gas.

[0041] The second type, see [link] Figure 3 The electrolysis assembly 2 includes two electrodes 21 arranged side-by-side at intervals. Both electrodes 21 are vertically positioned within the second cavity 122, with their fixed ends connected to the bottom of the dissolved gas tank 1. At this time, portions of both electrodes 21 are located within the second cavity 122. An inner boss (not shown in the figure) extending towards the interior of the second cavity is provided at the bottom of the dissolved gas tank 1. The fixed ends of the two electrodes 21 are mounted on the inner boss, so that when the water level in the dissolved gas tank 1 is lower than the boss, the electrolysis assembly 2 automatically stops electrolysis and gas production.

[0042] The third type, see [link] Figure 4 The electrolysis assembly 2 includes two electrodes 21 arranged side-by-side with a gap between them. Both electrodes 21 are vertically positioned within the first cavity 121 and the second cavity 122, with their fixed ends connected to the top of the dissolved gas tank 1 and their free ends having a gap between them and the bottom of the second cavity 122. In this case, portions of both electrodes 21 are located within the first cavity 121 and the second cavity 122. Alternatively, the lower ends of the two electrodes 21 can be mounted on an inner protrusion at the bottom of the dissolved gas tank, with the tops of the two electrodes 21 fitting with the top of the second cavity with a clearance fit.

[0043] The fourth type, and its relation Figure 2 The difference is that the lower end of the first cavity 121 extends downward to the lowest point of the electrolysis component 2 and the bottom of the dissolved gas tank 1; both electrodes 21 are arranged laterally in the first cavity 121 and the second cavity 122, and their fixed ends are connected to the side wall of the dissolved gas tank 1. That is, the free ends of the two electrodes 21 extend laterally into the first cavity 121 after passing through the partition. At this time, parts of the two electrodes 21 are located in the first cavity 121 and the second cavity 122.

[0044] Special note: When the electrolysis unit 2 is powered in the forward direction, one of the motors is the positive electrode and the other is the negative electrode; conversely, when the electrolysis unit 2 is powered in the reverse direction periodically, that is, when the programmed commutation time is reached, the positive electrode becomes the negative electrode and the negative electrode becomes the positive electrode. This helps to remove the deposits attached to the electrode surface. When tap water flows through the dissolved air tank 1, it can wash away the small amount of deposits generated during the electrolysis process.

[0045] refer to Figure 6-7This embodiment also provides a gas water heater, which includes a water heater body 3, a heater 4, a water flow sensor 5, a controller 6, and a microbubble generator as described above. The water heater body 3 is provided with an inner cold water pipe 311, an inner hot water pipe 312, a water inlet 313, and a water outlet 314. The heater 4 is disposed on the water heater body 3, and its hot water outlet is connected to the water outlet 314 through the inner hot water pipe 312. The water outlet 314 is connected to the water point through an outer hot water pipe. Specifically, an aerator 7 is provided at the water point, and the aerator 7 is connected to the water outlet 314 through the outer hot water pipe. The microbubble generator is disposed on the water heater body. The inlet 102 of the dissolved air tank 1 is connected to the water inlet 313, and the water inlet 313 is connected to the tap water supply pipe at the front end of the water heater. The outlet 103 of the dissolved air tank 1 is connected to the cold water inlet of the heater 4 through the inner cold water pipe 311. A water flow sensor 5 is installed on the internal cooling water pipe 311 to detect the water flow rate through the internal cooling water pipe 311 in real time. A controller 6 is installed on the water heater body 3 and is electrically connected to the heater 4, the electrolysis component 2 and the water flow sensor 5.

[0046] like Figure 6 As shown, when the water heater is in standby mode and the user is not using water, the water flow sensor 5 detects a flow rate less than the start-up flow rate. The controller 6 applies a certain voltage (preferably less than 36V DC) between the two electrodes of the electrolysis component 2. If the water level in the dissolved gas tank 1 is higher than the minimum operating point of the electrolysis component 2, the water will be electrolyzed by the electrolysis component 2 to produce hydrogen and oxygen. The oxygen and hydrogen produced by the electrolysis rise and accumulate inside the dissolved gas tank 1, slowly displacing the water in the dissolved gas tank 1. At this time, since the water outlet of the water heater is not discharging, the water in the dissolved gas tank 1 is discharged from the inlet 101 of the dissolved gas tank 1 back to the tap water supply pipe at the front end of the water heater. When the water level in the dissolved gas tank 1 is lower than the minimum operating point of the electrolysis component 2, the electrolysis component 2 automatically stops electrolysis and gas production. At this time, the dissolved gas tank 1 is filled with a hydrogen-oxygen mixture.

[0047] like Figure 7As shown, after the dissolved gas tank 1 completes electrolysis and gasification, when the user uses hot water at the water point, if the water flow sensor 5 detects a water flow rate greater than the start-up flow rate, the controller controls the heater to start heating the cold water flowing through the heater. Simultaneously, tap water flows from the inlet 102 of the dissolved gas tank 1 into the first chamber 121, flows through the diversion hole 101 of the partition, and is dispersed and sprayed out, forming a sprinkler-like spray that fully mixes with the hydrogen-oxygen mixture inside the dissolved gas tank 1, thus forming microbubble water with a gas-liquid mixing ratio of approximately 1% to 3%. This water then flows out from the outlet 103 of the dissolved gas tank 1, is heated by the heater, and finally flows to the water point, meeting the user's requirements for microbubble water. If the water flow sensor detects a water flow rate less than the start-up flow rate, indicating that the user has turned off the water, the controller shuts off the heater and restarts the electrolysis and gasification process. It can be seen that during electrolysis and gasification, no high-pressure air pump or liquid level sensor is required, no noise is generated, the cost is low, and it saves internal installation space.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
