Detailed Description
The following detailed description of specific embodiments of the invention refers to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.
The following describes a water heater 100 according to the present invention with reference to the drawings, in which the water heater 100 can discharge micro-nano bubble water having high micro-nano bubble density, and is simple to control, silent, and small in size.
Referring to fig. 1, 2, 5-8, the water heater 100 of the present invention includes a heat exchange unit 1, a controlled gas dissolving unit 2, a bath water pipe assembly 3 and a bubble water pipe assembly 4. The heat exchange device 1 is connected with a cold water inlet flow passage 11 and a hot water outlet flow passage 12, the gas dissolving control device 2 comprises a gas-liquid mixing cavity 21 provided with a gas inlet air passage 22, and the hot water outlet flow passage 12 is connected to the gas-liquid mixing cavity 21. The bubble water pipeline assembly 4 and the bathing water pipeline assembly 3 are connected in parallel through a pipeline and connected to a cavity water outlet 211 of the control air dissolving device 2, the bubble water pipeline assembly 4 comprises a micro-nano bubble water generating device 41 which is arranged in the bubble water pipeline assembly 4 and is internally provided with a bubble water micro-channel 431, and air dissolved water of the cavity water outlet 211 forms micro-nano bubble water to be discharged through the bubble water micro-channel 431.
the existing water heater applying the micro-nano bubble technology mostly adopts a pressurizing and air dissolving method, and a pressurizing water pump needs to be configured for pressurizing, so that the running noise and the vibration of the water heater are large, the series running and control are complex, and the user experience is poor. And, the volume of water pump is great for the volume of water heater is great. In addition, the increase of the water pump leads to the whole cost rising of water heater, and the price/performance ratio is low, and product competitiveness descends. Compared with the existing water heater adopting a pressurizing and air dissolving method, the water heater 100 disclosed by the invention has the advantages that the air dissolving control device 2 is connected to the hot water outlet channel 12 of the heat exchange device 1, the bubble water pipeline assembly 4 is connected to the air dissolving control device 2, and the bubble water pipeline assembly 4 comprises the micro-nano bubble water generating device 41 with the bubble water micro-channel 431 arranged inside, so that the water heater 100 can discharge micro-nano bubble water with high micro-nano bubble density. More importantly, the water heater 100 disclosed by the invention does not need a water pump, is simple and silent to control, has a small volume, meets the use requirements of users, can meet the consumption requirements of consumers on miniaturization and light weight of household appliances, and improves the product competitiveness.
optionally, referring to fig. 1 and 2, the hot water outlet flow passage 12 connected between the gas-liquid mixing chamber 21 and the heat exchanger 1 may be a normal pressure flow passage, that is, the gas-liquid mixing chamber 21 may be directly communicated with the hot water outlet flow passage 12 without a water pump to feed water. In addition, in order to facilitate air intake, an air pump 221 may be disposed in the air intake passage 22 to supply air, and a check valve 222 for preventing air and liquid from flowing out may be disposed in the air intake passage 22 between the air inlet of the air-liquid mixing chamber 21 and the air pump 221.
The water heater 100 of the invention has a small volume, and both the heat exchange device 1 and the gas dissolving control device 2 can be integrated in the water heater shell of the water heater 100. In addition, as shown in fig. 1 and 2, the water heater 100 of the present invention has two water outlet pipe assemblies, one is the bubble water pipe assembly 4, and the other is the bath water pipe assembly 3. The bubble water pipeline assembly 4 comprises a bubble water pipeline, a micro-nano bubble water generating device 41, a water outlet tap and a water outlet tap switch. The micro-nano bubble water generating device 41 can be integrally installed in the water outlet end part of the bubble water pipeline assembly 4, for example, the micro-nano bubble water generating device 41 can be integrally installed with a water outlet faucet (not shown in the figure), so that the installation structure of the water heater 100 is simpler. The bath water line assembly 3 can then include a bath water line, a bath outlet and an outlet switch.
Because the water heater 100 of the present invention has a two-way water outlet line assembly, the water heater 100 may also include an operating range selector and a controller. The working gear selector is provided with a bath water gear and a bubble water gear, and the controller is communicated with the working gear selector and used for determining the working gear of the working gear selector. When water needs to be discharged from the bath water pipeline assembly 3, the bath water gear can be selected through the working gear selector; when water needs to be discharged from the bubble water pipeline assembly 4, the bubble water gear can be selected through the working gear selector, and therefore the controller can perform corresponding control according to different working gears.
Further, the water heater 100 may include a water flow sensor 111, the water flow sensor 111 being in communication with the controller and being configured to detect the water flow in the cold water inlet channel 11. When the user turns on the tap switch of the bubble water pipe assembly 4 or the water outlet member switch of the bath water pipe assembly 3, the water flow rate sensor 111 can detect the liquid flow signal of the cold water inlet flow passage 11 when the hot water outlet flow passage 12 is turned on. Wherein, the water inlet control valve 121 of the hot water outlet flow passage 12 may be set to a normally open state.
When water needs to be discharged from the bath water pipeline assembly 3, the operating gear selector is used for selecting a bath water gear and turning on a water outlet component switch of the bath water pipeline assembly 3, at the moment, the controller is controlled to determine that the operating gear of the operating gear selector is a bath water gear, the air pump 221 is stopped to operate, air is stopped from being supplied to the air-liquid mixing cavity 21, the water inlet control valve 121 of the hot water outlet flow channel 12 is opened, water is supplied to the air-liquid mixing cavity 21, and at the moment, water in the air-liquid mixing cavity 21 flows out from the bath water pipeline assembly 3. When the switch of the water outlet component of the shower water pipe assembly 3 is turned off, the water flow sensor 111 cannot detect the water flow signal of the cold water inlet channel 11, the water inlet control valve 121 of the hot water outlet channel 12 is turned off, and the control of the controller is ended.
When water needs to be discharged from the bubble water pipeline assembly 4, the bubble water gear is selected through the working gear selector, and a water outlet tap switch of the bubble water pipeline assembly 4 is turned on. The controller performs the operation of closing the water inlet control valve 121 of the hot water outlet flow passage 12 and operating the air pump 221 in the air inlet passage 22 each time the water flow signal detected by the water flow sensor 111 for the first time (the first time) after the user opens the outlet tap switch, and at this time, controls the air dissolving device 2 to enter the air inlet process. And the controller does not perform the control of closing the water inlet control valve 121 of the hot water outlet flow passage 12 and operating the air pump 221 in the air inlet duct 22 each time the water flow sensor 111 does not initially detect the water flow signal after the user turns on the outlet tap switch.
Selecting a bubble water gear and opening a water outlet tap switch of the bubble water pipeline assembly 4, when the controller determines that the working gear of the working gear selector is the bubble water gear and determines that the water flow sensor 111 detects a water flow signal for the first time, controlling the air inlet process of the controller to close the water inlet control valve 121 of the hot water outlet flow channel 12, stopping the hot water inlet into the gas-liquid mixing chamber 21, operating the air pump 221 in the air inlet air passage 22, and introducing air into the gas-liquid mixing chamber 21. If water exists in the gas-liquid mixing chamber 21 at this time, the water in the gas-liquid mixing chamber 21 flows out from the water outlet tap of the bubble water pipe assembly 4 during the air intake process. When the controller determines that the operation time of the air pump 221 reaches the preset air intake time and after the gas-liquid mixing chamber 21 is filled with part or all of the gas, the air intake process is ended and the water intake and gas dissolving process is started, at this time, the water intake and gas dissolving process of the controller is controlled to stop operating the air pump 221, air intake to the gas-liquid mixing chamber 21 is stopped, and the water intake control valve 121 is opened to supply water to the gas-liquid mixing chamber 21. At this time, the pressure in the gas-liquid mixing chamber 21 is the same as the water inlet pressure, in the high-pressure gas-liquid mixing chamber 21, the water entering the gas-liquid mixing chamber 21 contacts with the gas in the gas-liquid mixing chamber 21 and starts to dissolve the gas to form gas-dissolved water, and the gas-dissolved water in the gas-liquid mixing chamber 21 flows to the bubble water pipeline assembly 4 and flows out of the micro-nano bubble water to the water outlet faucet through the pressure released by the micro-nano bubble liquid generating device 41.
when the opening time of the intake water control valve 121 reaches the preset intake time, the intake water and air dissolving process is finished and the intake process is started again, at this time, the controller controls to close the intake control valve 121 when the intake water and air dissolving process is finished, stop supplying water to the gas-liquid mixing chamber 21, operate the air pump 221, and start supplying air to the gas-liquid mixing chamber 21. Namely, after the water outlet tap switch is turned on each time and before the water outlet tap switch is turned off, the controller continuously and alternately circulates the air inlet process and the air inlet and dissolving process until the water outlet tap switch is turned off, the bubble water pipeline assembly 4 is closed, and if the water inlet control valve 121 is turned on, and the water flow sensor 111 cannot detect a water flow signal, the controller controls the flow to be ended.
It will be appreciated by those skilled in the art that the water inlet and gas dissolving process is not limited to time control, but may be liquid level control, for example, in which case the water heater further comprises a liquid level sensor (not shown) disposed in the gas-liquid mixing chamber 21, the liquid level sensor being in communication with the controller. When the liquid level sensor detects that the water in the gas-liquid mixing cavity 21 reaches a preset liquid level, the water inlet and gas dissolving process is finished and the gas inlet process is started again. The control of the controller at this time is the same as the control of the controller when the opening time of the water inlet control valve 121 reaches the preset water inlet time, and will not be described herein again.
because the size of the water passing hole of the bubble water micro-channel 431 is generally small, the water flow is inevitably small, and particularly when the water pressure of inlet water is small, the water outlet amount is smaller, so that the normal water using requirement of a user is difficult to meet. Therefore, the micro-nano bubble liquid generating device 41 may further include a gap passing flow channel 44 besides the bubble water micro flow channel 431, when the water pressure of the inlet water is low, the gap passing flow channel 44 may be turned on to increase the water output of the micro-nano bubble liquid generating device 41, and when the water pressure of the inlet water is high, the gap passing flow channel 44 may be turned off to discharge the micro-nano bubble water from the bubble water micro flow channel 431 of the micro-nano bubble liquid generating device 41.
in some embodiments, the micro-nano bubble water generating device 41 is provided with an axially through micro-nano bubbler accommodating chamber 421, and may include a housing portion 42, a micro-nano bubbler 43 and a flow-limiting driving member 46. Wherein, micro-nano bubbler 43 movable mounting holds in the chamber 421 in micro-nano bubbler, and little bubbler 43 is link up to bubble water microchannel 431 axial, and clearance water channel 44 can form between the outer wall of little nano bubbler 43 and the cavity inner wall that little nano bubbler held the chamber 421, and little nano bubbler 43 is driven along the axial displacement of little nano bubble water generating device 41 to current-limiting driving piece 46. Wherein the main flow direction of the inlet water in the housing portion 42 is defined as the axial direction of the housing portion 42.
Specifically, an annular limiting bearing platform part can protrude inwards from the inner wall of the micro-nano bubbler accommodating cavity 421, the limiting bearing platform part comprises a top annular bearing platform 422 facing the top of the housing part 42, a bubbler expanding part 433 is formed on the top of the micro-nano bubbler 43, and a step bottom 4331 of the bubbler expanding part 433 and the top annular bearing platform 422 can form annular sealing contact so as to stop the gap water flowing channel 44. It should be noted that a position relatively close to the central axis of the micro-nano bubbler 1 is defined as "inside", and a position relatively far away from the central axis of the micro-nano bubbler 1 is defined as "outside". In addition, the current-limiting driving member 46 may be an elastic member, one end of which abuts against the housing portion 42, and the other end of which is elastically biased against the micro-nano bubbler 43. When the water inlet pressure is smaller than the compression force of the elastic part, the micro-nano bubbler 43 is jacked up by the elastic part, the step bottom 4331 is separated from the top annular bearing platform 422, the inlet water flows out from the bubble liquid micro-channel 431 and the gap water-passing channel 44, and the micro-nano bubble liquid generating device 41 has the same function as a common faucet; when the water inlet pressure is greater than the compression force of the elastic piece, the micro-nano bubbler 43 moves downwards, the elastic piece is compressed until the water pressure is large enough, the step bottom 4331 is in sealing contact with the top annular bearing platform 422, the micro-nano bubbler 43 seals the gap water flowing channel 44, and water can only flow out through the bubble liquid micro-channel 431. At this time, the gas dissolved in the water flows out of the bubble liquid micro channel 431, and after the pressure is released, micro-nano bubble water is formed and flows out. Of course, the flow restricting drive member 46 is not limited to being a resilient member, but may be a mutually exclusive resilient member, or the like.
in some embodiments, the micro-nano bubble water generating device 41 is provided with an axially through micro-nano bubbler accommodating chamber 421, and may include a housing portion 42 and a micro-nano bubbler 43. Wherein, micro-nano bubbler 43 fixed mounting holds in the chamber 421 in micro-nano bubbler, and little bubbler 43 is link up to bubble water microchannel 431 axial. The micro-nano bubbler 43 is further internally provided with an axially through hollow column cavity 432, the micro-nano bubble water generating device 41 further comprises a sealing column 45 movably inserted in the hollow column cavity 432 and a flow-limiting driving member 46, the gap water passing flow channel 44 is formed between the outer peripheral wall of the sealing column 45 and the inner wall of the cavity of the hollow column cavity 432, and the flow-limiting driving member 46 can drive the sealing column 45 to axially move so as to conduct or close the gap water passing flow channel 44.
Specifically, the micro-nano bubbler 43 further includes a bottom cap 434, and the bottom end of the sealing cylinder 45 is axially movably sleeved on the bottom cap 434. The top of the hollow cylindrical chamber 432 is formed as a flare chamber 4321, and the top of the sealing cylinder 45 is formed as a cylinder diameter-enlarged portion 451. As shown in fig. 7 and 8, the inner wall of the flared cavity 4321 may include a conical inner peripheral wall and an annular platform bottom wall, and an annular surface of the closed-gap water flowing channel 44 is formed between the bottom end surface of the column expanding portion 451 and the annular platform bottom wall for sealing contact. The current-limiting driving member 46 can be an elastic member, one end of the current-limiting driving member 46 is pressed against the sealing cylinder 45, the other end of the current-limiting driving member 46 is pressed on the bottom end cover 434, when the water inlet pressure is smaller than the compression force of the elastic member, the micro-nano bubbler 43 is jacked up by the elastic member, the bottom end surface of the cylinder diameter expanding part 451 is separated from the bottom wall of the annular bearing platform, the inlet water flows out from the bubble liquid micro-channel 431 and the gap water-flowing channel 44, and at the moment, the micro-nano bubble liquid generating device 41 has; when the water inlet pressure is greater than the compression force of the elastic part, the micro-nano bubbler 43 moves downwards, the elastic part is compressed until the water pressure is large enough, the bottom end surface of the column expanding part 451 is in sealing contact with the bottom wall of the annular bearing platform, the micro-nano bubbler 43 seals the gap water flow channel 44, and water can only flow out through the bubble liquid micro-flow channel 431. At this time, the gas dissolved in the water flows out of the bubble liquid micro channel 431, and after the pressure is released, micro-nano bubble water is formed and flows out. Of course, the flow restricting drive member 46 is not limited to being a resilient member, but may be a mutually exclusive resilient member, or the like. In addition, the bottom end cap 434 is provided with a continuous port that communicates with the interstitial water flow passage 44, and water in the interstitial water flow passage 44 flows out of the continuous port.
It should be noted that, in the process of dissolving air in water, when the water outlet pressure of the hot water outlet flow channel 12 is low, the gap water passing flow channel 44 of the micro-nano bubble liquid generating device 41 is conducted, so that the water outlet amount of the micro-nano bubble liquid generating device 41 is also large, and the normal water demand of the user is ensured. In addition, all valves in the invention can be normally open or normally closed as required. One or more bubble liquid micro channels 431 in the micro-nano bubble liquid generating device 41 can be arranged; the water inlet and the air inlet of the gas-liquid mixing chamber 21 can be arranged at the upper part of the gas-liquid mixing chamber 21 or at a position close to the upper part, and the cavity water outlet of the gas-liquid mixing chamber 21 can be arranged at the bottommost part of the gas-liquid mixing chamber 21 or at a position close to the bottom.
