  However, in the conventional liquid refining device, since the water stop mechanism of the drain pipe is realized in a small size, the gap that allows water to flow inside the drain valve becomes narrow, and clogging is likely to occur due to dust contained in the water. was there.

  The present invention has been made to solve the above-described problems, and includes a liquid refinement device capable of realizing a drainage mechanism that is less likely to be clogged, and a heat exchange air device, an air purifier, or an air conditioner using the same. The purpose is to provide.

  In order to achieve this object, the liquid refinement apparatus of the present invention includes a suction port for sucking air, a blow-out port for blowing out air sucked from the suction port, and a wind between the suction port and the blow-out port.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. Note that each of the embodiments described below shows a preferred specific example of the present invention. Therefore, the numerical values, shapes, materials, components, component arrangement positions, connection forms, and the like shown in the following embodiments are merely examples, and are not intended to limit the present invention. Therefore, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims showing the highest concept of the present invention are described as optional constituent elements. Moreover, in each figure, the same code | symbol is attached | subjected to the substantially same structure, The overlapping description is abbreviate | omitted or simplified.

(First embodiment)
First, with reference to FIG. 1 and FIG. 2, a schematic configuration of a liquid miniaturization apparatus 50 according to the first embodiment of the present invention will be described. FIG. 1 is a schematic cross-sectional view of the liquid micronizer 50 in the vertical direction. FIG. 2 is an explanatory diagram for explaining the operating principle of the liquid micronizer 50.

  The liquid micronizer 50 includes a suction port 2 that sucks air and a blower outlet 3 that blows out the air sucked from the suction port 2. In the liquid micronizer 50, the suction port 2 and the blower outlet 3 are provided. Air passages 15 to 17 are formed between them. Moreover, the liquid refinement | purification apparatus 50 is provided with the liquid refinement | purification chamber 1 provided in the air paths 15-17, and the suction inlet 2, the liquid refinement | miniaturization chamber 1, and the blower outlet 3 are connecting.

  The liquid micronization chamber 1 is a main part of the liquid micronizer 50 and is where water is miniaturized. In the liquid atomization apparatus 50, the air taken in through the suction port 2 is sent to the liquid atomization chamber 1 via the air passage 15. Then, the liquid micronizer 50 includes the water that has been refined in the liquid micronization chamber 1 in the air that passes through the air passage 16, and blows the air containing the water via the air passage 17. It is configured to blow out from the outlet 3.

  The liquid micronization chamber 1 is provided with a collision wall 12 that opens upward and downward. The collision wall 12 is provided by being fixed in the liquid miniaturization chamber 1. In addition, the liquid micronization chamber 1 is provided with a cylindrical pumping pipe 11 that pumps (pumps) water while rotating inside the collision wall 12. The pumping pipe 11 has an inverted conical hollow structure, and includes a circular pumping port 21 (see FIG. 2) below, and above the pumping pipe 11 and at the center of the inverted conical top surface. The rotating shaft 10 arranged in the vertical direction is fixed. By connecting the rotary shaft 10 to the rotary motor 9 provided on the outer surface of the liquid micronization chamber 1, the rotary motion of the rotary motor 9 is transmitted to the pumping pipe 11 through the rotary shaft 10, and the pumping pipe 11 rotates. .

  As shown in FIG. 2, the pumping pipe 11 includes a plurality of rotating plates 14 formed so as to protrude outward from the outer surface of the pumping pipe 11. The plurality of rotating plates 14 are formed so as to protrude outward from the outer surface of the water pumping pipe 11 with a predetermined interval in the axial direction of the rotating shaft 10. Since the rotating plate 14 rotates together with the pumping pipe 11, a horizontal disk shape coaxial with the rotating shaft 10 is preferable. The number of the rotating plates 14 is appropriately set according to the target performance and the dimensions of the pumping pipe 11.

  Further, the wall surface of the pumping pipe 11 is provided with an opening 13 penetrating the wall surface of the pumping pipe 11. The opening 13 of the pumping pipe 11 is provided at a position communicating with a rotating plate 14 formed so as to protrude outward from the outer surface of the pumping pipe 11. The size of the opening 13 in the circumferential direction needs to be designed according to the outer diameter of the portion of the pumping pipe 11 provided with the opening 13, and corresponds to, for example, 5% to 50% of the outer diameter of the pumping pipe 11. A diameter, more preferably, a diameter corresponding to 5% to 20% of the pumped-up pipe 11 is mentioned. Within the above range, the dimensions of the openings 13 may be the same.

  As shown in FIG. 1, a water storage unit 4 that stores water pumped by the pumping pipe 11 is provided below the liquid micronizing chamber 1 in the vertical direction below the pumping pipe 11. The water storage unit 4 has a depth so that a part of the lower part of the pumping pipe 11, for example, about one third to one hundredth of the conical height of the pumping pipe 11 is immersed. This depth can be designed according to the required pumping capacity. Moreover, the bottom face of the water storage part 4 is formed in a mortar shape toward a drain port 22 (see FIG. 3) described later.

  The water supply unit 7 supplies water to the water storage unit 4. A water supply pipe (not shown) is connected to the water supply unit 7, and water is supplied directly from the water supply pipe through a water pressure adjusting valve, for example. Note that the water supply unit 7 may be configured so as to pump water only from the water tank provided outside the liquid micronization chamber 1 in advance by a siphon principle and supply water to the water storage unit 4.

  The liquid refinement chamber 1 is provided with a water level detection unit 8 that detects the water level of the water storage unit 4. The water level detection unit 8 has a float switch 20. The float switch 20 is turned off when the water reservoir 4 has not reached a certain water level, and is turned on when the water reservoir 4 has reached a certain water level. This constant water level is set to such a level that the lower part of the pumping pipe 11 is immersed in the water stored in the water storage section 4. When the float switch 20 is off, water is supplied from the water supply unit 7 to the water storage unit 4, and when the float switch 20 is on, the supply of water from the water supply unit 7 to the water storage unit 4 is stopped. The water in the water reservoir 4 can be kept at a constant water level.

  A drain pipe 18 is connected to the bottom surface of the water reservoir 4. A circular drain port 22 (see FIG. 3) provided at a position to which the drain pipe 18 is connected is provided at the lowest position on the bottom surface of the water storage section 4 formed in a mortar shape. Water stoppage and drainage by the drain pipe 18 are realized by the rotation of the pump pipe 11. That is, the drainage pipe 18 and the pumping pipe 11 constitute a water stop mechanism and a pumping mechanism of the water storage unit 4. In addition, the detail of the water stop mechanism and drainage mechanism of the water storage part 4 by the drain pipe 18 and the pumping pipe 11 is later mentioned with reference to FIG.

  Here, the operation principle of water miniaturization in the liquid micronizer 50 will be described. When the rotating shaft 10 is rotated by the rotation motor 9 and the pumped water pipe 11 is rotated in accordance with the rotation, the water stored in the water storage unit 4 is pumped up by the water pumped pipe 11 by the centrifugal force generated by the rotation. The rotation speed of the pumping pipe 11 is set between 1000-5000 rpm. Since the pumping pipe 11 has an inverted conical hollow structure, the water pumped up by the rotation is pumped up along the inner wall of the pumping pipe 11. The pumped water is discharged from the opening 13 of the pumping pipe 11 through the rotating plate 14 in the centrifugal direction and scattered as water droplets.

  The water droplets scattered from the rotating plate 14 fly in the space surrounded by the collision wall 12 and collide with the collision wall 12 to be miniaturized. On the other hand, the air passing through the liquid refinement chamber 1 moves from the upper opening of the collision wall 12 into the collision wall 12 and contains water droplets crushed (miniaturized) by the collision wall 12 from the lower opening to the collision wall. 12 Move outside. Thereby, the air sucked from the suction port 2 of the liquid micronizer 50 can be humidified, and the humidified air can be blown out from the air outlet 3.

  Since the kinetic energy of the water scattered from the rotating plate 14 is attenuated by friction with the air inside the collision wall 12, it is preferable that the rotating plate 14 be as close to the collision wall 12 as possible. On the other hand, the closer the collision wall 12 and the rotating plate 14 are, the smaller the amount of air passing through the inside of the collision wall 12 is. Therefore, the lower limit of the distance is arbitrarily determined by the pressure loss and the amount of air passing through the inside of the collision wall 12.

  The liquid to be refined may be other than water, for example, a liquid such as hypochlorous acid water having bactericidal / deodorizing properties. The refined hypochlorous acid water is included in the air sucked from the suction port 2 of the liquid refinement device 50, and the air is blown out from the blowout port 3, so that the space in which the liquid refinement device 50 is placed is placed. Sterilization / deodorization can be performed.

  Next, with reference to FIG. 3, details of the water stop mechanism and the drainage mechanism of the water storage unit 4 by the drainage pipe 18 and the pumping pipe 11 will be described. FIG. 3 is a view for explaining a water stop mechanism of the water storage unit 4 by the drain pipe 18 and the water pump pipe 11.

  When the liquid micronizer 50 is in an operating state and the pumping pipe 11 is rotated, a vortex 24 is generated in the water of the water storage section 4 inside the pumping pipe 11 due to the centrifugal force of the rotation. And the pumping-up pipe 11 forms the space | gap 25 between the vortex center bottom part 23 which generate | occur | produces by the rotation, and the drain outlet 22 to which the drain pipe 18 was connected. Thereby, during operation of the liquid refinement device 50, it is possible to prevent the water in the water storage unit 4 from being drained from the drain port 22.

  On the other hand, when the rotation of the pump 11 is stopped, the water in the water storage unit 4 flows into the drain port 22. Thereby, when the operation of the liquid refinement device 50 is stopped, the water in the water storage section 4 can be drained from the drain port 22.

  In this way, even if the drain pipe 18 is not used, the water refining device 50 is suppressed (water stopped) from being drained from the drain port 22 during operation of the liquid refining device 50, and after the operation is stopped. Can drain the water of the water reservoir 4 from the drain port 22. Therefore, the liquid micronizer 50 can eliminate the need for a drain valve. As a result, the area of the drain port 22 can be increased or the drain pipe 18 can be thickened, thereby realizing a drain mechanism that is less likely to be clogged.

  In the present embodiment, the bottom surface of the water storage unit 4 is formed in a mortar shape toward the drain port 22. Thereby, when the pumping pipe 11 rotates, it becomes easy to give a centrifugal force with respect to the water stored in the water storage part 4, and it can make it easy to generate the vortex 24 in the water of the water storage part 4 inside the water pumping pipe 11, The generated vortex 24 can be continued stably. Further, when the rotation of the water pump 11 is stopped, the water stored in the water storage section 4 can be surely drained from the drain port 22.

  Here, with reference to FIG. 4, the positional relationship of the pumping port 21 and the drainage port 22 of the pumping pipe 11 is demonstrated. FIG. 4A is a schematic diagram showing an example of the positional relationship between the pumping port 21 and the drain port 22 when the pumping pipe 11 is viewed from above in the vertical direction, and FIG. It is the schematic diagram which showed another example of relationship.

  In the example illustrated in FIG. 4A, the drain port 22 is disposed so as to enter the inside of the pumping port 21. Thereby, the space | gap 25 of the vortex center bottom part 23 of the water which generate | occur | produces inside the pumping pipe 11 in the water storage part 4 by rotation of the pumping pipe 11 can be easily formed between the drain outlets 22. Therefore, the drainage from the drain port 22 can be stopped reliably while the liquid micronizer 50 is in operation. FIG. 4A shows a case where the center of the pumping port 21 and the center of the drainage port 22 are shifted from each other when the pumping pipe 11 is viewed from above in the vertical direction. It is more preferable that the center of the mouth 21 and the center of the drain port 22 are arranged to coincide with each other, that is, the pumping port 21 and the drain port 22 are arranged concentrically.

  Moreover, like the other example shown in FIG.4 (b), you may arrange | position so that the pumping port 21 and the drain port 22 may overlap. In this case, a gap 25 in the vortex center bottom 23 of water generated inside the pumping pipe 11 in the water storage section 4 by the rotation of the pumping pipe 11 can be formed between at least a part of the drain port 22. Therefore, while the liquid micronizer 50 is in operation, the water can not be completely stopped, but the amount of water drained from the drain port 22 can be suppressed by the gap 25 formed on the drain port 22.

  In order to form the gap 25 between the vortex center bottom 23 generated by the rotation of the pumping pipe 11 and the drainage port 22 to which the drainage pipe 18 is connected, the diameter of the pumping port 21 is the diameter of the drainage port 22. The larger it is, the better. For example, when the diameter of the drain port 22 is 1, it is preferable that the diameter of the pumping port 21 is 1.3 or more. The larger the diameter of the pumping port 21, the larger the gap 25 generated inside the pumping tube 11 in the water storage section 4 due to the rotation of the pumping tube 11, and the gap 25 can be easily formed between the drainage port 22. is there.

  Moreover, in order to form the space | gap 25 between the vortex center bottom part 23 which generate | occur | produces by rotation of the pumping pipe 11, and the drain port 22 to which the drain pipe 18 was connected, the area of the pumping port 21 is the drain port 22 The larger the area, the better. For example, when the area of the drain port 22 is 1, it is preferable that the diameter of the pumping port 21 is 1.7 or more. The larger the area of the pumping port 21, the larger the gap 25 generated inside the pumping pipe 11 in the water storage section 4 due to the rotation of the pumping pipe 11, and the gap 25 can be easily formed between the drainage port 22. is there.

  In addition, the shape of the drain port 22 does not necessarily need to be a circular shape, and may be a polygonal shape.

  FIG. 5 is a schematic perspective view of a heat exchange device 60 provided with the liquid micronizer 50 according to the first embodiment of the present invention. The heat exchange device 60 includes an indoor suction port 61 and an air supply port 64 provided inside a building, an exhaust port 62 and an outside air suction port 63 provided outside the building, and heat exchange provided in the main body. An element 65 is provided.

  The indoor suction port 61 sucks indoor air, and the sucked air is exhausted from the exhaust port 62 to the outside. The outside air inlet 63 sucks outside air outside, and the sucked outside air is supplied into the room through the air inlet 64. At this time, heat exchange is performed by the heat exchange element 65 between the air sent from the indoor suction port 61 to the exhaust port 62 and the outside air sent from the outside air suction port 63 to the air supply port 64.

  One of the functions of the heat exchange device is a device incorporating a device for vaporizing a liquid, such as a water vaporizer for humidification purposes or a hypochlorous acid vaporizer for sterilization / deodorization purposes. The heat exchange device 60 incorporates a liquid refining device 50 as a device for vaporizing the liquid. Specifically, the liquid refinement device 50 is provided on the air supply port 64 side of the heat exchange air device 60. Note that water supply and drainage to the liquid micronizer 50 are performed by a water supply / drainage pipe 51.

  The heat exchange air device 60 provided with the liquid refinement device 50 includes water or hypochlorous acid refined by the liquid refinement device 50 with respect to the outside air subjected to heat exchange by the heat exchange element 65, The air is supplied into the room through the air supply port 64. By using the liquid micronizer 50 as a mechanism for vaporizing these liquids, it is possible to obtain a heat exchange device 60 that is smaller and more energy efficient.

  The liquid refinement device 50 may be provided in an air purifier or an air conditioner instead of the heat exchange air device 60. One of the functions of an air purifier or an air conditioner is one that incorporates a device for vaporizing a liquid, such as a water vaporizer for humidification purposes or a hypochlorous acid vaporizer for sterilization / deodorization purposes. By using the liquid micronizer 50 as this device, a more compact and energy efficient air purifier or air conditioner can be obtained.

(Second Embodiment)
In the second embodiment, the structure of the pumping pipe 11 (specifically, the vortex 24 is generated in the water of the water storage section 4 by rotation, and the gap 25 is formed between the vortex center bottom 23 and the drain port 22 to stop the water. Is different from the first embodiment in the structure of the tip of the water pump 11. The configuration of the liquid refinement device 50 other than the structure of the tip of the pumping pipe 11 is the same as that of the first embodiment (FIGS. 1 and 2). Hereinafter, the description of the first embodiment will be omitted as appropriate, and differences from the first embodiment will be mainly described.

  With reference to FIGS. 6-8, the schematic structure of the front-end | tip part of the pumping-up pipe 11 in the liquid refinement | miniaturization apparatus 50 which concerns on 2nd Embodiment of this invention is demonstrated. FIG. 6 is a schematic perspective view of the tip of the pumped-up pipe 11. FIG. 7A is a schematic perspective view of the tip end section of the pumped-up pipe 11, and FIG. 7B is a schematic side view of the tip section of the pumped-up pipe 11. FIG. 8A is a schematic diagram of the pumping pipe 11 in the AA ′ section in FIG. 7B, and FIG. 8B is the pumping in the BB ′ section in FIG. 7B. 2 is a schematic diagram of a tube 11. FIG.

  As shown in FIG. 6, the pumping pipe 11 of the liquid refinement device 50 according to the second embodiment is located at the tip of the pumping pipe 11 as a pumping port for pumping up water from the water storage unit 4 during the rotation operation. The first pumping port 21a and the second pumping port 21b positioned above the first pumping port 21a are provided. The second pumping port 21b is formed not only at the position of the first pumping port 21a but also above the pumping tube 11 from a position where a rib portion 26 described later is formed.

  The first pumping port 21 a is a pumping port corresponding to the pumping port 21 in the first embodiment, and is formed in a circular shape reflecting the inverted conical hollow structure of the pumping tube 11.

  The second pumping port 21 b is a rectangular opening and is formed through the wall surface of the pumping pipe 11. A plurality of second pumping ports 21 b are formed in the circumferential direction of the wall surface of the pumping pipe 11. In the present embodiment, as shown in FIG. 8A, three second pumping ports 21 b having the same shape are formed in the circumferential direction of the pumping pipe 11. The total opening area in the circumferential direction of the second pumping port 21b is the pumping capacity of the first pumping port 21a (the pumping amount from the first pumping port 21a) and the pumping capacity of the second pumping port 21b (the second pumping port). The amount of pumped water from 21b) is designed.

  As shown in FIGS. 7A and 7B, the pumping pipe 11 has a plurality of rib portions 26 on the wall surface (the inner wall 11a side) between the first pumping port 21a and the second pumping port 21b. Is formed. The rib portion 26 has a column shape, and is formed so as to protrude from the inner wall 11 a of the water pumping pipe 11 toward the center side of the water pumping pipe 11. A plurality of ribs 26 are formed in the circumferential direction of the inner wall 11 a of the water pumping pipe 11. In the present embodiment, as shown in FIG. 8B, eight rib portions 26 having the same shape are formed in the circumferential direction of the inner wall 11a. In addition, the dimension, shape, number, arrangement, and the like of the rib portion 26 are designed in consideration of the water stopping capability of the water pump 11.

  Next, with reference to FIG. 9, the details of the water stop mechanism of the water storage unit 4 by the drain pipe 18 and the pumping pipe 11 in the liquid micronizer 50 according to the second embodiment will be described. FIG. 9 is a view for explaining a water stop mechanism of the water storage section 4 by the drain pipe 18 and the pumping pipe 11 in the liquid micronizer 50.

  As described in the first embodiment, when the liquid refinement device 50 is in an operating state and the pumping pipe 11 is rotated, the centrifugal force of the rotation causes the vortex 24 to flow into the water in the water storage section 4 inside the pumping pipe 11. Will occur. And the pumping-up pipe 11 forms the space | gap 25 between the vortex center bottom part 23 which generate | occur | produces by the rotation, and the drain outlet 22 to which the drain pipe 18 was connected. Thereby, during operation of the liquid refinement device 50, it is possible to prevent the water in the water storage unit 4 from being drained from the drain port 22 (see FIG. 3).

  In the present embodiment, as shown in FIG. 9, a plurality of rib portions 26 are formed at the distal end portion of the pumping pipe 11 in the circumferential direction of the inner wall 11 a of the pumping pipe 11. The plurality of rib portions 26 push the water in the region in the rotation direction by the rotation of the pumping pipe 11 and easily apply centrifugal force to the water in the region, so that the vortex 24 is generated in the water in the region. Easy to do. That is, if the rotation operation (rotation speed) of the pumping pipe 11 is the same, the vortex 24 generated by the rib portion 26 can be strengthened. As a result, the gap 25 generated between the vortex center bottom 23 generated by the rotation and the drain port 22 to which the drain pipe 18 is connected is strengthened, and the force (stopping) for suppressing the amount of water drained from the drain port 22 is increased. Hydropower) is improved. In particular, the effect of improving the water stopping power is remarkable when the water pump 11 is operated at a low rotational speed.

  On the other hand, since the operation when the rotation of the water pump 11 is stopped is the same as that of the first embodiment, the description thereof is omitted.

  Next, pumping by the pumping pipe 11 of the liquid micronizer 50 according to the second embodiment will be described with reference to FIG.

  As described in the first embodiment, in the liquid refinement device 50, when the rotary shaft 10 is rotated by the rotary motor 9 and the pumping pipe 11 is rotated in accordance with the rotation shaft 10, the centrifugal force generated by the rotation causes the water storage unit 4 to rotate. The stored water is pumped up by the pumping pipe 11. Since the pumping pipe 11 has an inverted conical hollow structure, the water pumped up from the pumping port 21 of the pumping pipe 11 by rotation is pumped upward along the inner wall of the pumping pipe 11 (see FIG. 2). reference).

  In this embodiment, as shown in FIG. 9, the pumping pipe 11 has the 1st pumping port 21a and the 2nd pumping port 21b as a pumping port. The water pumped up from each of the first pumping port 21 a and the second pumping port 21 b of the pumping pipe 11 by the rotation is pumped upward along the inner wall of the pumping pipe 11. In particular, since the second pumping port 21b is provided above the region where the vortex 24 is created (the region of the first pumping port 21a and the rib portion 26), water is pumped regardless of the strength of the vortex 24 in the region. 11 is easily taken into the interior. Moreover, in this embodiment, compared with the pumping port of 1st Embodiment, since the whole pumping amount has increased by the part of the 2nd pumping port 21b, the stable operation | movement of the liquid refinement | miniaturization apparatus 50 is implement | achieved. be able to.

  As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed. For example, the numerical values given in the above embodiment are merely examples, and other numerical values can naturally be adopted.
