Description

Technical Field

[0001] This invention relates to the field of microbubble water preparation technology, and in particular to a microbubble water application device. Background Technology

[0002] Microbubbles are tiny bubbles with a diameter of less than 50 μm. Under certain pressure, they are formed by thoroughly mixing gas (such as air) with water to create a gas-water solution. The solution then expands and releases the pressure, causing the dissolved gas to suddenly coalesce into tiny microbubbles, resulting in a milky white color. The resulting microbubble water has strong cleaning power; the pressure and heat generated when the microbubbles burst instantly remove dirt, achieving a deep cleaning effect.

[0003] Existing water-using appliances such as water heaters, water dispensers, and humidifiers generally lack the function of generating microbubbles, or only offer the concept without a concrete structure, and usually do not have flow regulation capabilities, thus failing to meet users' different water flow requirements. Therefore, how to design a water-using appliance that can incorporate microbubble water generation is a problem that needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide a microbubble water device that can output microbubble water with an adjustable flow rate, thus meeting the different water usage requirements of different users.

[0005] To achieve this objective, the present invention adopts the following technical solution:

Each microbubble water generator includes a throat and a gas cutting element, the gas cutting element being disposed at the throat of the throat, allowing outside air to enter the throat through the micro-gap of the gas cutting element and mix with water to form microbubble water.

[0007] Preferably, the gas cutting element is a gasket, which is stacked along the axial direction of the throat tube at the throat of the throat tube, and the micro-gap is formed between the gaskets.

[0008] Preferably, the sidewalls of the gaskets have a surface roughness, and the microgap is formed between the sidewalls of adjacent gaskets.

[0009] Preferably, the gasket has several shearing grooves on both sides of its axial direction.

[0010] Preferably, the microbubble water generator further includes an air inlet pipe, and the gas cutting element is a plate disposed in the air inlet pipe, the plate having a plurality of the micro gaps.

[0011] Preferably, the intake pipe is provided with a one-way valve, which is located upstream of the plate.

[0012] Preferably, the plate is provided in multiple portions and spaced apart.

[0013] Preferably, the gas cutting element is a sintered filter element disposed at the throat, and the peripheral wall of the sintered filter element has a plurality of micro-gaps formed thereon.

[0014] Preferably, the microbubble water device further includes an air pump disposed within the housing, the microbubble water generator includes an air inlet pipe connected to the throat of the throat tube, and the air pump connected to the air inlet pipe.

[0015] Preferably, the microbubble water device further includes a controller disposed within the housing, the controller being connected to the flow regulating valve, the water pump, and the air pump.

[0016] The beneficial effects of this invention are as follows: By incorporating a gas cutting element into the microbubble water generator, air can enter the throat through the micro-gap of the gas cutting element and mix with water to form microbubble water. Furthermore, since at least two microbubble water generators and corresponding flow regulating valves are connected in parallel, the output flow rate of the microbubble water can be adjusted to meet the different water usage requirements of various users, thus improving the user experience.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0031] This invention provides a microbubble water device that generates microbubble water. Furthermore, the flow rate of the microbubble water output by this device is adjustable to meet the different water flow requirements of various users, thus improving the user experience. In this embodiment, the microbubble water device includes, but is not limited to, water heaters, water dispensers, humidifiers, and other water-using devices.

[0032] like Figure 1 As shown, the aforementioned microbubble water device includes a housing 2, a microbubble water generator 1, an inlet pipe 3, a flow regulating valve 4, a water pump 5, and an outlet pipe 6, all housed within the housing 2. At least two microbubble water generators 1 are connected in parallel, with their inlets connected to the inlet pipe 3 and their outlets connected to the outlet pipe 6. The flow regulating valve 4 is positioned between the inlet and the inlet pipe 3, and it adjusts the flow rate of water entering the microbubble water generator 1, thereby adjusting the flow rate of the microbubble water produced by the generator 1. This flow regulating valve 4 is a common flow adjustment structure in the prior art, and its specific structure and principle will not be elaborated upon here.

[0033] The aforementioned water pump 5 is connected to the water inlet pipe 3, and it is able to pump water into the water inlet pipe 3.

[0034] In this embodiment, it should be noted that the inlets of the at least two microbubble water generators 1 are connected to the same inlet pipe 3, and the outlets are connected to the same outlet pipe 6. When the at least two microbubble water generators 1 output microbubble water, all the output microbubble water is mixed in the outlet pipe 6 and finally delivered to the user's water supply point.

[0035] In this embodiment, an air pump (not shown in the figure) and a controller (not shown in the figure) may also be installed inside the housing 2. The air pump is used to supply air to the microbubble water generator 1 to generate microbubble water. In this embodiment, one air pump can supply air to at least two microbubble water generators 1 simultaneously through a branch pipeline, or each microbubble water generator 1 can be connected to an air pump to achieve individual control of each air path.

[0036] The aforementioned controller is a common control structure in the prior art. A controller is a master command device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system. In this embodiment, the controller is connected to the flow regulating valve 4, the water pump 5, and the air pump to realize the regulation and control of the water and air circuits.

[0037] In this embodiment, the microbubble water generator 1 includes a throat and a gas cutter 11, wherein the gas cutter 11 is disposed at the throat of the throat, allowing outside air to enter the throat through the micro-gap of the gas cutter 11 and mix with water to form microbubble water. One end of the throat is connected to the water inlet pipe 3, and the other end is connected to the water outlet pipe 6. For example, as shown... Figure 2 As shown, in this embodiment of the microbubble water generator 1, the gas cutting element 11 consists of multiple gaskets, which are stacked along the axial direction of the throat tube at the throat. By placing gaskets at the throat, air enters the throat tube through the micro-gap between the gaskets and mixes with water. Due to the small size of the micro-gap between the gaskets, the air can be sheared, thereby turning the air into finer air with higher pressure. Simultaneously, in conjunction with the throat tube structure, the water flow rate increases and the pressure decreases. This, combined with the higher-pressure finer air, allows more air to easily integrate into the water, resulting in microbubble water containing 10 bubbles per milliliter. 6 The microbubble water generator 1 of this invention produces better microbubble water and can continuously generate microbubble water. Moreover, the microbubble water generator 1 of this invention can produce microbubble water with a bubble diameter of 47 micrometers at 0.3 MPa, which is smaller than the bubble particle size produced by bubble generators in the prior art, and achieves better cleaning effect.

[0038] In one embodiment, such as Figure 2 As shown, the microbubble water generator 1 includes a gasket, an air inlet pipe 12, a first pipe 13, and a second pipe 14, wherein:

[0039] One end of the second pipe 14 is sealed inside the first pipe 13, forming the throat between them. A gasket is placed at the throat of the throat. Exemplarily, a first liquid channel 131 can be formed inside the first pipe 13, with one end for water from the inlet pipe 3 to enter. A second liquid channel 141 is formed inside the second pipe 14, with one end connected to the first liquid channel 131 and the other end connected to the outlet pipe 6. Along the direction pointing towards the gasket, the diameters of both the first liquid channel 131 and the second liquid channel 141 near the gasket gradually decrease to form a throat. When water is introduced, the throat generates an adsorption force that draws air into the micro-gap between the gaskets, where it is sheared into finer, higher-pressure air, which then mixes with the water to form microbubble water. It should be noted that, in addition to the negative pressure area of ​​the throat, this embodiment can also control the air supply using an air pump.

[0040] In this embodiment, at least two gaskets are provided between the first liquid channel 131 and the second liquid channel 141, and the first liquid channel 131, the at least two gaskets, and the second liquid channel 141 are sequentially connected. Water can flow through the first liquid channel 131, through the gaskets, and finally out through the second liquid channel 141. Air can enter the throat through the micro-gap between the two gaskets and mix with water to form microbubble water.

[0041] Preferably, one end of the second pipe 14 is threaded to the first pipe 13, and a gasket is sandwiched between the first pipe 13 and the second pipe 14. The threaded connection between the second pipe 14 and the first pipe 13 achieves a fixed connection between them. More importantly, by screwing on the second pipe 14, the clamping force applied to the gasket by the second pipe 14 and the first pipe 13 can be adjusted, thereby adjusting the size of the micro-gap between the gaskets to meet the requirements for generating different microbubble water.

[0042] In this embodiment, the first pipe 13 is provided with an air inlet and an annular chamber 132 communicating with the air inlet. An air intake channel 121 is provided inside the air intake pipe 12, and the air intake pipe 12 is sealed to the air inlet and the air pump, so that the air intake channel 121 communicates with the annular chamber 132. Outside air is pumped into the air intake channel 121 by the air pump, and then enters the annular chamber 132, where it is distributed in a ring. Subsequently, it enters the micro-gap between the gaskets evenly along the circumference of the gaskets, making the generation of microbubble water more uniform and the effect better. In this embodiment, the connection between the air intake pipe 12 and the first pipe 13 can also be a threaded connection and sealed with a sealing ring.

[0043] In this embodiment, the aforementioned gasket can be set to two or more as needed, thereby creating multiple micro-gaps and making the microbubble water generation faster.

[0044] It is understandable that micro-gap is also formed between the gasket and the first pipe 13 and between the gasket and the second pipe 14 in this embodiment. This micro-gap can also be used to shear air to form tiny gas particles, which enter the liquid channel at a higher flow rate and mix with the water in the liquid channel to form microbubble water.

[0045] In this embodiment, it can be referred to Figure 3 The aforementioned gaskets have a rough surface, which creates minute unevenness, resulting in micro-gaps between the two gaskets. Air passing through these micro-gaps is sheared and eventually mixes with water. The micro-gaps are formed solely by the inherent properties of the gasket material, eliminating the need for additional structures to aid in the generation of microbubbles. The structure is simple and easy to assemble.

[0046] As another preferred embodiment, a plurality of shear grooves 111 can be formed on the surfaces of the gaskets on both sides along the axial direction, and a micro gap is formed between the shear grooves 111 of two adjacent gaskets.

[0047] Optionally, the gasket can be made of a foam-like metal, in which case the shear groove 111 is a cavity in the foam-like metal. Alternatively, the gasket can be made of an alloy material, in which case the shear groove 111 can be created by directional etching. The gasket can also be cast from a porous plate, in which case the shear groove 111 is a cavity in the porous plate. Furthermore, the gasket can be formed by stacking layers of porous graphite, in which case the shear groove 111 is a cavity on the porous graphite.

[0048] In this embodiment, the plurality of shear grooves 111 can be arranged in parallel or crosswise. Figure 3 (as shown), to achieve shearing of the air inside the annular chamber 132.

[0049] For reference Figure 3The aforementioned gasket includes a first sheet 112 and a second sheet 113 arranged in a stepped pattern, which are integrally formed. The diameter of the first sheet 112 is smaller than the diameter of the second sheet 113, and both the first sheet 112 and the second sheet 113 have shear grooves 111 on their surfaces. This gasket structure allows an annular space to be formed between its end face with the adjacent first pipe 13, the end face with the second pipe 14, and between two adjacent gaskets. When air flows into the annular chamber 132, the air is evenly distributed within the annular space, and then flows evenly into the micro-gap between the gasket and the first liquid channel 131, the micro-gap between the gaskets, and the micro-gap between the gasket and the second liquid channel 141, where it is sheared. This shearing process causes the fine air particles formed to be evenly mixed into the water, resulting in more uniform and comprehensive distribution of microbubble water.

[0050] In this embodiment, the gasket has a groove 114 on the side near the first liquid channel 131 and the second liquid channel 141, and a protrusion is provided at the end face of the first pipe 13 and the second pipe 14, which abuts against the groove 114. That is, the groove 114 and the protrusion allow the first pipe 13 and the second pipe 14 to clamp the gasket, thus fixing the gasket. More importantly, it makes the micro-gap formed by the shear groove 111 narrower, resulting in finer air shearing and a better microbubble water effect. It should be noted that the sidewall of the groove 114 in this embodiment can also have a shear groove 111.

[0051] For reference Figure 2 The microbubble water generator 1 in this embodiment further includes a third pipe 15, which is sealed to the end of the first pipe 13 away from the gasket, and the third pipe 15 has a third liquid channel 151 that communicates with the first liquid channel 131. An inlet is provided on the third pipe 15 that communicates with the third liquid channel 151. This inlet is connected to the water inlet pipe 3, and water in the water inlet pipe 3 can enter the third liquid channel 151 through the inlet, and then enter the first liquid channel 131. In this embodiment, one end of the third pipe 15 is placed inside the first pipe 13, and the two are sealed together by a sealing ring.

[0052] Preferably, a detection device 16 is provided at one end of the third pipe 15. This detection device 16 is used to detect flow rate, pressure, and / or temperature. For example, the detection device 16 can be a temperature sensor to detect the temperature of the water flowing into the third liquid channel 151, a pressure sensor to detect the pressure of the water flowing into the third liquid channel 151, or a flow sensor to detect the flow rate of the water flowing into the third liquid channel 151. Devices that simultaneously detect two or more of temperature, pressure, and flow rate can also be used. By detecting flow rate, pressure, and / or temperature, a controller can be used to control the water flow rate, pressure, and temperature to meet different needs.

[0053] In another preferred embodiment, the microbubble water generator 1 described above can also be as follows: Figure 4 The structure shown illustrates that the microbubble water generator 1 includes a throat and an air inlet pipe 12 connected to the throat of the throat. A plate (which is the gas cutter 11 of this invention) is installed inside the air inlet pipe 12. The plate has multiple micro-gap structures, allowing air to enter the throat and mix with water to form microbubble water. By placing a plate inside the air inlet pipe 12 with multiple micro-gap structures, air can be sheared into multiple streams of higher-pressure fine air through these gaps. Simultaneously, the flow rate of water within the throat increases while the pressure decreases. This, combined with the higher-pressure fine air, allows for greater and easier integration of air into the water, resulting in microbubble water containing up to 10 bubbles per milliliter. 6 The microbubble water generator 1 of this invention produces better microbubble water and can continuously generate microbubble water. Moreover, the microbubble water generator 1 of this invention can produce microbubble water with a bubble diameter of 47 micrometers at 0.3 MPa, which is smaller than the bubble particle size produced by bubble generators in the prior art, and achieves better cleaning effect.

[0054] Specifically, such as Figure 4 As shown, the microbubble water generator 1 includes a plate, a first pipe 13, a second pipe 14, and an air inlet pipe 12, wherein:

[0055] One end of the second pipe 14 is sealed inside the first pipe 13, forming the aforementioned throat between them. The air intake pipe 12 has an air intake channel 121, which connects to both the air pump and the throat of the throat. Exemplarily, a first liquid channel 131 can be provided inside the first pipe 13 for the entry of water from the water inlet pipe 3. The end of the first liquid channel 131 near the second pipe 14 includes a first diameter-reducing section 1311, whose diameter gradually decreases along the direction pointing towards the second pipe 14. A second liquid channel 141 is provided in the second pipe 14, with one end connected to the first liquid channel 131 and the other end used for the outflow of microbubble water. The second liquid channel 141, near the end of the first liquid channel 131, includes a second variable-diameter section 1411 and a constant-diameter section 1412. The constant-diameter section 1412 connects the second variable-diameter section 1411 and the first variable-diameter section 1311 (i.e., the constant-diameter section 1412 is the throat of the throat tube). Along the direction pointing towards the first pipe 13, the diameter of the second variable-diameter section 141 gradually decreases. With this structure, the first liquid channel 131 and the second liquid channel 141 together form the aforementioned throat tube structure. When water is introduced, the throat tube generates an adsorption force that draws air into the micro-gap of the plate, where it is sheared into finer, higher-pressure air. This fine air is then drawn to the throat and mixes with water to form microbubble water.

[0056] In this embodiment, a threaded connection hole 133 is provided in the middle of the first pipe 13. Figure 5 and Figure 6 As shown), a gas communication hole 142 is provided on the second pipe 14. Figure 4 and Figure 7 As shown), the gas communication hole 142 connects the equal diameter section 1412 and the threaded connection hole 133. One end of the air intake pipe 12 is threaded to the threaded connection hole 133 so that the air intake channel 121 is connected to the gas communication hole 142 to form the aforementioned air intake channel 121, thereby allowing air to enter the throat of the throat pipe through the air intake channel 121 and mix with water.

[0057] Preferably, refer to Figures 4-7The first liquid channel 131 within the first pipe 13, without the first diameter reducing section 1311, has a stepped structure at one end. Correspondingly, the second pipe 14, near the first pipe 13, also has a stepped structure at one end. This facilitates the positioning of the portion of the second pipe 14 within the first pipe 13, ensuring that the gas communication hole 142 on the second pipe 14 aligns directly with the threaded connection hole 133 on the first pipe 13, allowing air to smoothly enter the throat of the throat. Furthermore, it improves the sealing performance of the connection between the first pipe 13 and the second pipe 14, preventing gas leakage at the connection point. More preferably, the outer wall of the portion of the second pipe 14 within the first pipe 13 has several sealing grooves 143, within which sealing rings can be placed to further enhance the sealing performance between the first pipe 13 and the second pipe 14.

[0058] In this embodiment, one end of the second pipe 14 is fixedly connected to the first pipe 13 by bolts. Specifically, flange structures can be provided on the first pipe 13 and the second pipe 14, and then the first pipe 13 and the second pipe 14 are fixed by bolts and flange structures. The first pipe 13 and the second pipe 14 can also be fixed by other methods such as threaded connection, as long as the gas communication hole 142 is aligned with the threaded connection hole 133.

[0059] The aforementioned plate is disposed within the threaded connection hole 133 and can be fixed by abutting one end of the air intake pipe 12. The plate has multiple micro-gap sections. Air enters through the air intake channel 121 of the air intake pipe 12, passes through the plate, flows into the threaded connection hole 133 via the micro-gap sections, and finally flows into the throat of the throat pipe through the gas communication hole 142. Because there are multiple micro-gap sections, the air can be sheared and divided into multiple streams of higher-pressure fine air. These fine air streams mix with water to form microbubble water.

[0060] In this embodiment, multiple plates can be configured, spaced apart. These multiple plates allow for repeated shearing and segmentation of the air, resulting in finer air entering the threaded connection hole 133 and thus enhancing the microbubble water effect. Preferably, the micro-gap of the multiple plates is staggered to improve the shearing effect on the air, causing it to be sheared into more strands, thereby increasing the number of bubbles in the microbubble water.

[0061] For example, the aforementioned plate can be made of foam-like metal, in which case the micro-gaps are formed by the pores of the foam-like metal. The aforementioned plate can also be made of porous plate or porous graphite, in which case the micro-gaps are formed by the pores on it.

[0062] In this embodiment, a one-way valve (not shown in the figure) is provided in the air intake channel 121. It is preferably provided in the air intake channel 121 of the air intake pipe 12, and the one-way valve is provided upstream of the plate to prevent water from flowing into the air intake channel 121 through the threaded connection hole 133.

[0063] For reference Figure 4 The microbubble water generator 1 in this embodiment further includes a third pipe 15, which is sealed to one end of the second pipe 14, and the third pipe 15 has a fourth liquid channel 152 that communicates with the second liquid channel 141. An outlet communicating with the fourth liquid channel 152 is provided on the third pipe 15, and this outlet is connected to the water outlet pipe 6, allowing the generated microbubble water to flow into the water outlet pipe 6. In this embodiment, the third pipe 15 and the second pipe 14 are sealed together by a threaded connection and a sealing ring.

[0064] In another preferred embodiment, the microbubble water generator 1 described above can also be as follows: Figure 8 The structure shown, specifically, is as follows: Figure 8 As shown, the microbubble water generator 1 includes a throat tube, and sintered filter elements (which are the gas cutting element 11 of this invention) are stacked along the axial direction of the throat tube. Air can enter the throat tube through the micropores of the sintered filter element and mix with water to form microbubble water. This invention, by setting a sintered filter element at the throat tube, allows air to enter the throat tube and mix with water due to the micropore structure of the sintered filter element itself. Because the micropores of the sintered filter element are small, they can shear the air, thus turning it into finer air with higher pressure. Simultaneously, the throat tube structure increases the water flow rate and lowers the pressure. Combined with the higher-pressure finer air, this allows more air to easily and readily integrate into the water, resulting in microbubble water containing up to 10 bubbles per milliliter. 6 The microbubble water generator 1 of this invention produces better microbubble water and can continuously generate microbubble water. Moreover, the microbubble water generator 1 of this invention can produce microbubble water with a bubble diameter of 47 micrometers at 0.3 MPa, which is smaller than the bubble particle size produced by bubble generators in the prior art, and achieves better cleaning effect.

[0065] like Figure 8 As shown, the microbubble water generator 1 includes a sintered filter element, an air inlet pipe 12, a first pipe 13, and a second pipe 14, wherein:

[0066] One end of the second pipe 14 is sealed inside the first pipe 13, and the two together form a throat with the sintered filter element, which is disposed at the throat of the throat. Exemplarily, a first liquid channel 131 is provided inside the first pipe 13, one end of which is used for the entry of water from the inlet pipe 3. The end of the first liquid channel 131 near the second pipe 14 includes a first diameter-reducing section 1311, and the diameter of the first diameter-reducing section 1311 gradually decreases along the direction pointing towards the second pipe 14. A second liquid channel 141 is provided in the second pipe 14, one end of which is connected to the first liquid channel 131, and the other end is connected to the outlet pipe 6. The second liquid channel 141 includes a second diameter-reducing section 1411 at its end near the first liquid channel 131. Along the direction pointing towards the first pipe 13, the diameter of the second diameter-reducing section 1411 gradually decreases. A sintered filter element is disposed between the first diameter-reducing section 1311 and the second diameter-reducing section 1411. This structure allows the first liquid channel 131, the sintered filter element, and the second liquid channel 141 to collectively form the aforementioned throat structure. When water is introduced, the throat generates an adsorption force that draws air into the micro-gap between the sintered filter elements, where it is sheared into finer, higher-pressure air, which then mixes with the water to form microbubble water.

[0067] A threaded connection hole 133 is provided on the first pipe 13, which is positioned directly opposite the sintered filter element. Through this threaded connection hole 133, outside air can flow to the sintered filter element and then enter the throat through the micro-gap of the sintered filter element. In addition, the air intake pipe 12 of this embodiment can be threaded to the threaded connection hole 133. An air intake channel 121 is provided in the air intake pipe 12, which connects the air pump and the threaded connection hole 133. Outside air is pumped into the air intake channel 121 by the air pump, then enters the threaded connection hole 133, and finally enters the micro-gap of the sintered filter element.

[0068] Preferably, one end of the second pipe 14 is fixedly connected to the first pipe 13 by bolts. Specifically, flange structures can be provided on the first pipe 13 and the second pipe 14, and then the first pipe 13 and the second pipe 14 are fixed by bolts and flange structures. The first pipe 13 and the second pipe 14 can also be fixed by other methods such as threaded connection.

[0069] In this embodiment, a rubber gasket 17 is provided between the sintered filter element and the first pipe 13. This rubber gasket 17 prevents water flow from impacting the sintered filter element and causing damage. The water pressure is buffered by the rubber gasket 17 and does not directly act on the end face of the sintered filter element, thus effectively protecting it. Furthermore, the rubber gasket 17 also prevents the sintered filter element from being damaged by impact or pressure during the assembly of the microbubble water generator 1 in this embodiment.

[0070] For reference Figure 8 The microbubble water generator 1 in this embodiment also includes a third pipe 15, which is sealed to the end of the first pipe 13 away from the sintered filter element. The third pipe 15 has a third liquid channel 151 that connects to the first liquid channel 131, and this third liquid channel 151 connects to the water inlet pipe 3. An inlet port connecting to the third liquid channel 151 is provided on the third pipe 15, allowing water from the water inlet pipe 3 to enter the third liquid channel 151 through the inlet port, and then enter the first liquid channel 131. In this embodiment, one end of the third pipe 15 is placed inside the first pipe 13, and the two are fixedly connected by a flange and bolts, with a sealing ring provided between them for sealing.

[0071] Preferably, a detection device 16 is provided at one end of the third pipe 15. This detection device 16 is used to detect flow rate, pressure, and / or temperature. For example, the detection device 16 can be a temperature sensor to detect the temperature of the water flowing into the third liquid channel 151, a pressure sensor to detect the pressure of the water flowing into the third liquid channel 151, or a flow sensor to detect the flow rate of the water flowing into the third liquid channel 151. Devices that simultaneously detect two or more of temperature, pressure, and flow rate can also be used. By detecting flow rate, pressure, and / or temperature, a controller can be used to control the water flow rate, pressure, and temperature to meet different needs.
