Description

  The present invention relates to an evaporation device that evaporates drain water discharged from a main device such as a hand dryer.

  Conventionally, some hand dryers guide water blown from wet hands to a water receiver and store a predetermined volume of water in the water receiver. Before the stored water overflows from the water receiver, water is discarded at the time of cleaning the main body of the hand dryer. When such a water discarding operation is required, the trouble of periodically checking the water level of the water receiver becomes complicated. Therefore, a technique has been proposed in which an evaporating means for evaporating the water stored in the water receiver is provided in the hand dryer. For example, Patent Document 1 proposes a technique in which a water receiver and a transpiration member are provided in a chamber that is a passage for air to be ejected during operation of a hand dryer. The water stored in the water receiver promotes evaporation by blowing air during a manual drying operation or blowing air in a specific evaporation mode.

  There is also a technique in which water is absorbed by a transpiration member provided in the water receiver and evaporation is promoted by blowing air from a blower provided outside the water receiver. For example, Patent Document 2 proposes a hot water heater technique that evaporates drain water absorbed by a cloth serving as a transpiration member. Patent Document 3 proposes a technique of a low-temperature showcase in which drain water absorbed by an evaporating cloth that is a transpiration member is evaporated by blowing air. In the technique of providing the transpiration member in the water receiver, the maximum water retention amount of the transpiration member is always maintained by utilizing the capillary phenomenon caused by the transpiration member. Evaporation of drain water is promoted by blowing air toward the transpiration member while gaining an effective vaporization area by the transpiration member.

  When the evaporator is used, when the water receiver or the transpiration member is contaminated, it is necessary to clean the water receiver or the transpiration member. In addition, the transpiration member is replaced with respect to the contamination or deterioration of the transpiration member. For example, in the configuration in which the water receiver and the transpiration member are provided in the chamber as in the technique of Patent Document 1, it is necessary to check whether airtightness in the chamber is ensured each time cleaning or replacement of the transpiration member is performed. It will take a lot of trouble for maintenance. Moreover, when a film such as dirt is formed on the surface of a transpiration member containing an antibacterial agent, it becomes difficult to exert a sufficient antibacterial action. For this reason, if the maintenance such as cleaning and replacement of the transpiration member is not performed, the bacteria contained in the stored water will propagate, causing problems such as the generation of odor during hand drying.

  Moreover, when a water receiver is fixed in a main body apparatus like the technique of patent document 2 or 3, it will take the effort of opening a main body apparatus for every maintenance which requires attachment or detachment of a water receiver. Furthermore, all of the techniques disclosed in Patent Documents 1 to 3 require that the apparatus has a configuration for providing drain water evaporation means in advance. For this reason, it is very difficult to provide the retrofitting means in the existing equipment, and if the entire configuration is changed in order to provide the evaporation means in the existing equipment, a great burden is placed on the user.

  The present invention has been made in view of the above, and it is a first object of the present invention to provide an evaporation apparatus that can reduce maintenance labor. In addition, a second object of the present invention is to obtain an evaporation device that can reduce the time and effort required for installation on existing equipment.

  In order to solve the above-described problems and achieve the object, the present invention is an evaporation device that is attached to a main body device that generates drain water and evaporates the drain water discharged from the main body device, the drain device comprising: A water receiver that stores water, a transpiration member that absorbs and evaporates the drain water stored in the bottom of the water receiver, and a blower that blows air to the transpiration member, and at least the water receiver And the said transpiration | evaporation member is provided so that attachment or detachment is possible from the said main body apparatus as integral.

  Further, the present invention is an evaporation device that is attached to a main body device that generates drain water and evaporates the drain water discharged from the main body device, wherein the water receiver stores the drain water, and the water receiver. A transpiration member that absorbs and evaporates the drain water stored in the bottom of the container, and a blower that blows air to the transpiration member, and the water receiver, the transpiration member, and the blower are integrated. It is provided so that it can be attached or detached from the main device.

  ADVANTAGE OF THE INVENTION According to this invention, there exists an effect that the effort of maintenance, such as cleaning and replacement | exchange of a transpiration member, can be reduced by making a water receptacle and a transpiration member integrally removable from a main body apparatus.

  In addition, according to the present invention, the water receiver, the transpiration member, and the air blowing unit can be integrally attached to and detached from the main device, so that the water receiver and the evaporation device of the existing device can be replaced. There is an effect that it can reduce the trouble of installation.

  Below, based on drawing, the embodiment of the evaporation device concerning the present invention is described in detail.

Embodiment 1 FIG.
FIG. 1 is a perspective view of an evaporator 1 and a hand dryer 15 according to Embodiment 1 of the present invention. The evaporator 1 evaporates drain water discharged from the hand dryer 15 which is the main device. The hand dryer 15 includes a drying chamber 16 that is recessed in a U shape. A plurality of blowing nozzles 17 are formed on the upper part of the front wall surface and the upper part of the rear wall surface of the drying chamber 16. The drain port 18 is provided at the bottom of the drying chamber 16.

  When a hand wet with water is inserted into the drying chamber 16 from above the hand dryer 15, wind blows from the blowout nozzle 17. Water droplets adhering to both sides of the palm and the back are blown off by the wind from the blowing nozzle 17. The hand drying device 15 dries the hand by blowing off water droplets attached to the hand. Water droplets blown from the hand are received by the inner wall and the bottom of the drying chamber 16.

  FIG. 2 is a vertical sectional view of the configuration shown in FIG. The illustrated configuration represents a state in which a cross section is viewed from the front side of the evaporator 1 and the hand dryer 15. The evaporator 1 is disposed below the hand dryer 15. The evaporation apparatus 1 includes a water receiver 2, a blower 3, and a transpiration member 4. The upper end portion of the hose 7 is connected to the drain port 18. The lower end portion of the hose 7 is connected to an opening provided in the upper surface portion 8 of the water receiver 2.

  The water received at the inner wall and bottom of the drying chamber 16 becomes drain water and is introduced from the drain port 18 through the hose 7 to the water receiver 2. The water receiver 2 stores the drain water introduced through the hose 7. A space for storing drain water is provided at the bottom of the water receiver 2. The overflow hole 9 causes the drain water to overflow when the drain water stored at the bottom of the water receiver 2 becomes full. The overflow hole 9 is provided mainly to prevent the drain water from being applied to the blower 3.

  An air supply port 5 through which air flows from the outside of the evaporator 1 is provided on one side surface of the water receiver 2. An exhaust port 6 through which air is discharged from the evaporator 1 to the outside is provided on the side surface of the water receiver 2 opposite to the side surface on which the air supply port 5 is provided.

  The transpiration member 4 absorbs and drains the drain water stored at the bottom of the water receiver 2. The transpiration member 4 is configured using a material having high water absorption and high transpiration, for example, porous fibers. The transpiration member 4 is disposed between the air supply port 5 and the exhaust port 6, and is disposed downstream of the blower 3 with respect to the blower 3.

  The transpiration member fixing means 10 fixes the transpiration member 4 on the opposite side of the water receiver 2 from the bottom side. The transpiration member 4 is integrated with the water receiver 2 by fixing the upper end of the transpiration member 4 to the water receiver 2 by the transpiration member fixing means 10. The transpiration member 4 is suspended inside the water receiver 2 so that the lower end thereof is in contact with the drain water stored at the bottom of the water receiver 2. The blower 3 takes in air outside the evaporator 1 from the air supply port 5 and blows it toward the transpiration member 4. The air taken in from the air supply port 5 travels toward the exhaust port 6 through the transpiration member 4.

  FIG. 3 is a partial cross-sectional view including the blower 3 in the configuration in which the evaporator 1 is attached to the hand dryer 15. The structure shown in FIG. 3 represents the state which looked at the cross section perpendicular | vertical to the cross section shown in FIG. 2 from the evaporation member 4 side. The blower fixing means 11 fixes the blower 3 to the hand dryer 15. The blower fixing means 11 includes an L-shaped member 11a and an I-shaped member 11b.

  In the L-shaped member 11a, a portion extended from the blower 3 to the back side of the hand drying device 15 and a portion fixed to the hand drying device 15 are substantially orthogonal, and has an L shape in the illustrated cross section. ing. The I-shaped member 11b extends upward from the blower 3 toward the hand dryer 15, and has an I-shape in the cross section shown in the drawing. The L-shaped member 11a and the I-shaped member 11b fix the blower 3 to the hand dryer 15 by screwing, for example.

  FIG. 4 is a perspective view of the water receiver 2 removed from the hand dryer 15. By fixing the blower 3 to the hand drying device 15 by the blower fixing means 11, the evaporation device 1 can be easily attached and detached with the configuration other than the blower 3 as a single unit while leaving the blower 3 in the hand drying device 15. .

  FIG. 5 is a top view of the evaporator 1 in a state in which the upper surface portion 8 (see FIG. 2) is removed from the water receiver 2. A plurality of transpiration members 4 are provided inside the water receiver 2. Each of the transpiration members 4 has an uneven shape in which concave portions and convex portions are alternately provided in the illustrated plane. Each transpiration member 4 is configured by bending a sheet-like member at a plurality of locations. The plurality of transpiration members 4 are provided in parallel in a direction (vertical direction in FIG. 5) that is substantially perpendicular to the traveling direction of air from the blower 3. All of the transpiration members 4 are arranged with intervals between them so as to have an uneven shape. Between the transpiration members 4, the air path 13 which meanders along uneven | corrugated shape is formed.

  Even if the transpiration member 4 is a thin material that has a flat shape and has a low strength and is bent by its own weight, the transpiration member 4 can have a concavo-convex shape to provide strength and maintain the shape. By making it possible to maintain the shape of the transpiration member 4, the configuration of the air passage 13 can be easily maintained against the wind. Moreover, the filling rate of the transpiration member 4 can be increased while the air passage 13 is secured by narrowing the interval at which the transpiration member 4 is arranged. By providing many transpiration members 4 in the water receiver 2 whose volume size is determined, a large surface area for vaporizing the drain water can be secured.

  Moreover, by making the transpiration member 4 into a concavo-convex shape, the surface area can be increased and the wind can be easily brought into contact with the transpiration member 4 as compared with the case where the transpiration member 4 has a flat plate shape. Therefore, the evaporation apparatus 1 can promote effective evaporation of drain water only by air blowing without heating the air sent to the transpiration member 4 with a heater or the like.

  The transpiration member support means 19 supports the plurality of transpiration members 4. The transpiration member support means 19 supports each transpiration member 4 by fixing the upper end portion of each transpiration member 4 between the upstream side and the downstream side of the air blowing. The transpiration member fixing means 10 has a shape in which the transpiration member support means 19 can be fitted. The transpiration member fixing means 10 fixes the plurality of transpiration members 4 by fitting the transpiration member support means 19 that supports the plurality of transpiration members 4.

  The plurality of transpiration members 4 supported by the transpiration member support means 19 can be handled as a single structure as a whole. The plurality of transpiration members 4 can be easily detached from the water receiver 2 by pulling out and inserting the transpiration member support means 19 from the transpiration member fixing means 10.

  The water blown off from the hand by the high-speed air flow blown from the blow-off nozzle 17 (see FIG. 2) is introduced into the water receiver 2 through the drain port 18 provided at the lower part of the drying chamber 16 through the hose 7. . A part of the drain water introduced into the water receiver 2 is directly absorbed by the transpiration member 4, or travels along the inner wall of the water receiver 2 and is stored at the bottom of the water receiver 2. The drain water stored at the bottom of the water receiver 2 is sufficiently sucked up to the transpiration member 4 by capillary action. The air flowing into the water receiver 2 from the air supply port 5 by the blower 3 takes moisture from the surface of the transpiration member 4 by passing through the air passage 13 and is discharged from the drain port 6 to the outside of the water receiver 2. The In this way, the evaporation apparatus 1 promotes evaporation of moisture.

  The evaporator 1 can facilitate maintenance such as cleaning of the water receiver 2 and replacement of the transpiration member 4 by making the configuration other than the blower 3 simple and detachable. It is also possible to easily wash the water receiver 2 and the transpiration member 4 with water. When the transpiration member 4 is replaced, it is only necessary to remove the transpiration member 4 from the transpiration member fixing means 10 together with the transpiration member support means 19 and replace the transpiration member 4 with a new one. The time and effort of exchange can be greatly reduced.

  In addition, the evaporation apparatus 1 should just be detachable from a main body apparatus by uniting at least the water receiver 2 and the transpiration | evaporation member 4, and may deform | transform suitably. For example, a configuration other than the water receiver 2 and the transpiration member 4 may be detachable from the main body device, and elements other than the blower 3 may be left in the main body device when the water receiver 2 and the transpiration member 4 are attached and detached.

Embodiment 2. FIG.
FIG. 6 is a partial cross-sectional view including the blower 103 in the configuration in which the evaporation apparatus 101 according to the second embodiment is attached to the hand drying apparatus 15. FIG. 7 is a perspective view of the water receiver 102 removed from the hand dryer 15. The evaporation apparatus 101 according to the present embodiment is characterized in that the water receiver 102, the transpiration member 4, and the blower 103 are detachably provided as a unit from the hand dryer 15.

  The evaporation apparatus 101 according to the present embodiment has a configuration related to the introduction and supply / exhaust of drain water, a configuration of the transpiration member 4, a configuration for fixing the transpiration member 4 to the water receiver 102, an arrangement of the blower 103, and the like. This is the same as the evaporation apparatus 1 according to the first embodiment. The components common to the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The water receiver 102 includes a blower fixing unit 111 that fixes the blower 103. The blower fixing means 111 is provided on the front side and the back side of the hand dryer 15 with respect to the blower 103. The blower fixing means 111 has a convex rail shape. The blower 103 includes a concave rail receiving portion 112 formed so that the blower fixing means 111 can be fitted therein. The blower 103 is installed inside the water receiver 102 by fitting the blower fixing means 111 to the rail receiving portion 112 and inserting it from the side surface of the water receiver 102. The blower 103 can be removed from the water receiver 102 by being pulled out of the water receiver 102.

  The positions and numbers of the blower fixing means 111 and the rail receiving portions 112 are not limited to those shown in the drawing, and may be appropriately modified. For example, the blower fixing means 111 and the rail receiving portion 112 may have different heights from the bottom of the water receiver 102 on the front side and the back side of the hand dryer 15. In this case, it is possible to prevent an error in the orientation of the blower 103 with respect to the water receiver 102.

  By fixing the blower 103 to the water receiver 102 by the blower fixing means 111, the evaporation device 101 can be attached to and detached from the hand drying device 15 by integrating the water receiver 102, the transpiration member 4, and the blower 103. Thereby, it can replace with the water receiver provided in the existing main body apparatus, and can install easily with the evaporation apparatus 101 which concerns on this Embodiment.

  The evaporator 101 has a power plug 120 connected to the blower 103. The evaporator 101 can supply power of, for example, AC 100V to the blower 103 by inserting the power plug 120 into an outlet. This makes it possible to supply power to the blower 103 when the evaporator 101 is retrofitted to an existing main device.

  The blower 103 is provided with a through hole through which the cord of the power plug 120 passes from the inside of the evaporator 101 to the outside, and the power plug 120 is drawn out of the evaporator 101 from the through hole. Thereby, when removing the air blower 103 from the water receiver 102, the power plug 120 can be prevented, and the power plug 120 can be prevented from being immersed in the drain water stored in the water receiver 102.

  The evaporator 101 can be removed from the hand dryer 15 by integrating the water receiver 102, the transpiration member 4, and the blower 103, so that maintenance such as cleaning of the water receiver 102 and replacement of the transpiration member 4 can be performed. It becomes possible. When washing the water receiver 102 or the transpiration member 4 with water, it is desirable to remove the blower 103 from the water receiver 102. Thereby, it can prevent that water blows to the air blower 103 in the case of washing with water.

  By sliding the blower 103 from the side surface of the water receiver 102 along the blower fixing means 111, the blower 103 can be easily detached from the evaporator 101. Thereby, elements other than the blower 103 in the evaporator 101 can be cleaned with water or the like. Further, by removing the blower 103, a wide working space can be secured when replacing the transpiration member 4 and the like, and workability can be improved.

  The evaporation apparatus 101 according to the present embodiment can be replaced with a water receiver attached to a conventionally used hand drying apparatus, and is generally used by preparing a power source. It can be attached to a drying device. As a result, it is possible to eliminate the need for a large-scale replacement work that requires replacement of the main unit, and to reduce the trouble of installation to existing equipment.

  Note that the evaporation apparatus described in each embodiment is not limited to the one applied to the hand dryer 15. The main device to which the evaporation apparatus is applied may be any device that generates drain water. For example, the evaporator may be applied to a heat exchanger in which condensed water is generated and used for evaporation of condensed water.

  As described above, the evaporation apparatus according to the present invention is useful when applied to a hand dryer.
