Utility model registration No. 3172527

Therefore, in view of the above-mentioned circumstances, an object of the present invention is to provide a spraying device for spraying a liquid containing useful components into a room, a method of using the spraying device, and an air conditioning method using the spraying device. It is.

In order to solve the above problems, the spray device according to the present invention includes:
"A tank for storing liquid,
a lower roller rotatably provided around an axis extending horizontally within the tank;
at least one upper roller provided above the lower roller and rotatable around an axis parallel to the lower roller;
a mesh-like endless belt that is wound around the lower roller and the upper roller and has a mesh size of 3 mm to 7.5 mm ;
a frame body having a pair of vertical frames that pivotally supports the lower roller so as to be movable in the vertical direction and also pivotally supports the upper roller;
a roller motor that rotates at least one of the upper rollers to rotate the endless belt;
a fan for passing wind through the endless belt and discharging it to an external space;
and a fan motor for rotating the fan.

Examples of "liquids" include solutions in which baked shell powder is added to a solvent, solutions in which ingredients with sterilizing effects are dissolved in a solvent, solutions in which ingredients with antibacterial effects are dissolved in a solvent, and deodorizing effects. Examples include a solution in which a component having an aromatic effect is dissolved in a solvent, and a solution in which a component having an aromatic effect is dissolved in a solvent. Furthermore, the "liquid" may be a dispersion or suspension having a solid content, or a solution having no solid content.

Examples of the "tank" include a tank whose upper end is at a height between the lower roller and the upper roller, and a tank whose upper end is higher than the upper roller.

The spraying device having this configuration can be used by the following method of using the spraying device. That is,
"While the liquid containing an excessive amount of baked seashell powder is contained in the tank to a height at which at least a portion of the lower roller is immersed, the liquid contained in the tank is stirred. However, the roller motor rotates the endless belt via the upper roller so that the liquid adheres to the endless belt, and the fan motor rotates the fan.

Further, the spray device having this configuration can be used in the following air conditioning method using the spray device. That is,
"A liquid to which an excessive amount of baked seashell powder has been added is stored in the tank to a height where at least a portion of the lower roller is immersed, and the liquid contained in the tank is transferred to the roller motor. The particles are attached to the endless belt while being agitated by the endless belt rotating via the upper roller, and the particles are attached to the endless belt by the wind sent by the rotation of the fan by the fan motor. This is an air conditioning method in which liquid is turned into fine droplets and released into the room along with the wind.

The type of shellfish used for the "shell" is not particularly limited, and scallops, oysters, surf clams, clams, clams, etc. can be used. In Japan, scallop shells are said to be the most common type of shell that is disposed of as industrial waste, accounting for over 60% of all shells, so it is desirable to use scallop shells from the standpoint of effective resource utilization. .

When the crystal phase of shell powder is identified by X-ray diffraction, the main component of unfired shells is calcium carbonate, but when heated above 700°C, a diffraction peak of calcium oxide becomes visible, and when heated above 1000°C, When heated, it becomes almost a single phase of calcium oxide. Therefore, it is desirable that the firing temperature of the "fired shell powder" be 1000°C or higher.

Calcium oxide, which is the main component of shell powder fired at high temperatures, is hydrated and becomes calcium hydroxide when dissolved in a solvent such as a mixture of ethanol and water or water, increasing the pH of the liquid. . As this pH increases, the sterilizing effect and the effect of suppressing bacterial growth (hereinafter referred to as "antibacterial effect") increase.

When using the spraying device of this configuration, a tank is filled with liquid to a height at which at least a portion of the lower roller is immersed, and the lower roller provided in the tank is submerged. Since an endless belt is wound around the lower roller and the upper roller, a portion (lower part) of the endless belt is immersed in the liquid contained in the tank. In this state, when the upper roller is rotated by the roller motor to make the endless belt go around, the side of the endless belt that approaches the lower roller (outward path side) penetrates into the liquid in the tank, and the side that goes away from the lower roller ( On the return trip (on the return trip), it moves upward from within the liquid in the tank, and an endless belt circulates through the liquid. As a result, in a portion of the endless belt above the liquid level, the liquid may adhere to the irregularities in the mesh, or the liquid may adhere in the form of a film that blocks the mesh.

Then, when the fan is rotated by the fan motor while the endless belt is rotating, the wind generated by the rotation of the fan is discharged into the external space through the mesh-like endless belt. At this time, the liquid adhering to the unevenness of the mesh is blown away, and the liquid film blocking the mesh is bursting, causing the liquid adhering to the endless belt to become minute droplets, causing the minute droplets to form. Droplets can be released on the wind. Thereby, the liquid contained in the tank can be made into fine droplets and sprayed into the external space (outside the device). Therefore, by storing a liquid containing useful components in a tank and using it, the liquid can be sprayed.

Then, as a liquid having useful components, a liquid to which an excessive amount of fired seashell powder (hereinafter also referred to as "fired seashell powder") is added is stored in the tank of the spray device having this configuration and used. This makes it possible to spray a liquid that has sterilizing and antibacterial effects. In addition, by storing a liquid containing an excessive amount of baked seashell powder in the tank of the spray device of this configuration and using it in a room, it is possible to easily spray the liquid that has sterilizing and antibacterial effects all over the room. can clean the environment.

As described above, as an effect of the present invention, it is possible to provide a spraying device for spraying a liquid containing useful components into a room, a method of using the spraying device, and an air conditioning method using the spraying device.

It is a diagram. FIG. 2 is a front view showing a belt mechanism in the spray device of FIG. 1. FIG. FIG. 2 is an explanatory diagram schematically showing the inside of a spray device according to a second embodiment of the present invention. FIG. 2 is an explanatory diagram schematically showing an air conditioning system that air-conditions an entire building using a spray device according to a third embodiment of the present invention.

A spray device 1 according to a first embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. In FIG. 1(a), the inside of the spray device 1 is shown from the side. The spray device 1 includes a tank 10 that is open upward and accommodates the liquid S, a belt mechanism 20 whose lower part is inserted into the tank 10, and a fan 11 provided above the tank 10. A fan motor 12 that rotates the fan 11; a box-shaped case 13 that houses the tank 10, the belt mechanism 20, the fan 11, and the fan motor 12; and an operation provided on the top of the case 13. 14 and four casters 15 attached to the lower surface of the bottom wall of the case 13.

The tank 10 is made of a translucent material so that when the tank 10 contains the liquid S, the amount of the liquid S contained therein can be seen from the outside through the wall surface. The tank 10 is attached to the lower end inside the case 13.

As shown in FIG. 2, the belt mechanism 20 includes a lower roller 21 that is rotatably provided around an axis that extends in the horizontal direction, and an axis that is parallel to the lower roller 21 above the lower roller 21. An upper roller 22 that is rotatably provided around the upper roller 22, a net-like endless belt 23 that is wound around the lower roller 21 and the upper roller 22, and a roller that rotates the upper roller 22 to make the endless belt 23 go around. It has a motor 24.

The belt mechanism 20 also includes a drive gear 25 attached to the rotating shaft of the roller motor 24, a driven gear 26 that meshes with the drive gear 25 and rotates integrally with the upper roller 22, a lower roller 21, an upper roller 22, and a frame body 27 to which a roller motor 24 is attached.

The lower roller 21 includes a cylindrical roller body 21a around which the endless belt 23 is wound, flange portions 21b provided at both ends of the roller body 21a, and a shaft portion extending outward from the flange portions 21b at both ends. 21c. The flange portion 21b of the lower roller 21 prevents the endless belt 23, which is wound around the roller body 21a, from moving in the axial direction.

The upper roller 22 includes a cylindrical roller body 22a around which the endless belt 23 is wound, flange portions 22b provided at both ends of the roller body 22a, and a shaft portion extending outward from the flange portions 22b at both ends. 22c. The flange portion 22b of the upper roller 22 prevents the endless belt 23, which is wound around the roller body 21a, from moving in the axial direction. A driven gear 26 is attached to the tip of one shaft portion 22c of the upper roller 22.

Further, the upper roller 22 has a friction increasing portion 22d at the center of the roller body 22a for increasing friction with the endless belt 23. This friction increasing portion 22d further prevents the endless belt 23 from moving in the axial direction.

It is desirable that the mesh size of the endless belt 23 be within the range of 3 mm to 7.5 mm. The reason for this is that if the mesh size is smaller than 3 mm, the amount of air passing through the endless belt 23 will decrease and there is a risk that a sufficient amount of air will not be obtained. On the other hand, if the mesh is larger than 7.5 mm, the amount of liquid S that adheres to uneven parts such as the intersections of the mesh of the endless belt 23 will be reduced, and it will be difficult to form a liquid film that closes the mesh. This is because there is a possibility that it will not be possible to spray a sufficient amount of fine droplets.

The driven gear 26 is a bevel gear, and is attached to the tip of one shaft portion 22c of the upper roller 22. Drive gear 25 is a bevel gear. Therefore, the axis of the upper roller 22 and the axis of the rotating shaft of the roller motor 24 are perpendicular to each other.

The frame body 27 includes a pair of vertical frames 27a that are spaced apart from each other in the left and right directions and are vertically long, and a pair of horizontal frames 27b that connect the pair of vertical frames 27a. The pair of horizontal frames 27b connects a portion near the upper end and a portion above the lower end of the pair of vertical frames 27a, respectively. The frame body 27 supports the shaft portions 21c at both ends of the lower roller 21 so as to be movable in the vertical direction within a predetermined range at a portion of the pair of vertical frames 27a below the lower horizontal frame 27b. . Thereby, by changing the vertical position at which the lower roller 21 is pivotally supported, the tension of the endless belt 23 wound around the lower roller 21 and the upper roller 22 can be adjusted.

Further, the frame body 27 pivotally supports the shaft portions 22c at both ends of the upper roller 22 at a portion of the pair of vertical frames 27a that is lower than the upper horizontal frame 27b. One shaft portion 22c of the upper roller 22 extends outward longer than the vertical frame 27a, and a driven gear 26 is attached to the tip thereof. The roller motor 24 is attached near the upper end of the vertical frame 27a near the driven gear 26, with the rotating shaft protruding downward.

The belt mechanism 20 is formed such that, when assembled into the spray device 1, the lower roller 21 is located near the bottom of the tank 10, and the upper roller 22 is located above the fan 11. The belt mechanism 20 is attached near the rear end inside the case 13 with the axial directions of the lower roller 21 and the upper roller 22 facing in the left-right direction when viewed from the front. Therefore, the endless belt 23 wound around the lower roller 21 and the upper roller 22 has its surface oriented in the front-rear direction (in the direction perpendicular to the plane of the paper in FIG. 2).

The fan 11 and the fan motor 12 are mounted in the case 13 in front of the belt mechanism 20 (on the left in FIG. 1(a)) with their rotational axes directed in the front-rear direction. Therefore, by rotating the fan 11 with the fan motor 12, air can be blown in the front-rear direction.

The case 13 is formed in the shape of a vertically long rectangular parallelepiped. The tank 10 is attached to the lower end of the case 13 so as to be slidable rearward, and the tank 10 can be pulled out to the rear beyond the rear wall of the case 13. The case 13 has a spout 13a penetrating the front wall at a portion above the tank 10, and an intake port 13b penetrating at a portion of the rear wall opposite to the spout 13a. There is.

Although not shown, the case 13 is provided with a louver for changing the direction in which the liquid S is sprayed from the spout 13a.

The operation unit 14 is provided with switches for power, air volume, timer, swing, operation mode, and the like. The caster 15 is a swivel caster with a stopper function.

Note that the spraying device 1 may be provided with a sensor that detects the amount of the liquid S contained in the tank 10, and the sensor may be notified when the amount of the liquid is lower than a predetermined amount.

In the spraying device 1 of this embodiment, the roller body 21a of the lower roller 21 and the roller body 22a of the upper roller 22 in the belt mechanism 20 are formed of rubber, and the endless belt 23 is formed of synthetic resin or rubber. . Further, other members of the belt mechanism 20 except for the roller motor 24 are made of synthetic resin. This makes the belt mechanism 20 resistant to rust.

Next, a method of using the spray device 1 of this embodiment and an air conditioning method using the spray device 1 will be explained. First, the tank 10 of the spray device 1 is pulled out from the case 13 rearward, and after the liquid S is contained in the tank 10, the tank 10 is slid forward and set in the case 13. Since the upper end of the tank 10 is lower than the upper roller 22 and the fan 11, the upper roller 22 and the fan 11 will not be immersed even when the tank 10 is filled with liquid S. The liquid S has the baked seashell powder P dissolved in a solvent, and a mixture of ethanol and water or water can be suitably used as the solvent.

As the baked seashell powder P, in this embodiment, a powder obtained by baking and pulverizing scallop shells at a temperature of 1100° C. or higher is used. The particle size (diameter) of this powder was measured using a laser diffraction/scattering particle size distribution analyzer (Microtrac MT3300, manufactured by Nikkiso Co., Ltd.), and the volume-based median diameter was about 5 to 10 μm. Calcium carbonate, which is the main component of shells, is turned into calcium oxide by firing at a temperature of 1100° C. or higher, and calcium oxide turns into calcium hydroxide through hydration. Incidentally, the solubility of calcium hydroxide in water is approximately 0.16 at 20°C.

In the liquid S used in this embodiment, there is an excessive amount of fired seashell powder P in the tank 10 (an amount that is more than enough to saturate the solvent in the tank 10). Therefore, the concentration of the liquid S is a saturated concentration, and exhibits high alkalinity with a pH of 12 or higher. This liquid S has sterilizing and antibacterial effects against bacteria such as Campylobacter, Escherichia coli (O157, O7, etc.), Salmonella, Staphylococcus aureus, and Vibrio parahaemolyticus. Moreover, the liquid S has an effect (deodorizing effect) of reducing the concentration of malodorous components such as ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, and acetic acid.

When the tank 10 contains the liquid S and is set in the case 13, the lower roller 21 of the belt mechanism 20 provided in the tank 10 is submerged in the liquid S. Since the endless belt 23 is wound around the lower roller 21 and the upper roller 22, the lower part of the endless belt 23 is immersed in the liquid S contained in the tank 10.

In this state, when operation is started by operating the operation unit 14, the upper roller 22 is rotated by the roller motor 24 and the endless belt 23 is rotated, and the fan 11 is rotated by the fan motor 12 to blow air. is started. When the endless belt 23 starts rotating, the side of the endless belt 23 that approaches the lower roller 21 (outward path side) enters the liquid S in the tank 10, and the side that moves away from the lower roller 21 (return path side) enters the liquid S in the tank. It will move upward from within the liquid S in 10. As a result, the endless belt 23 circulates through the liquid S, and in the portions of the endless belt 23 above the liquid level, the liquid S may adhere to the unevenness of the mesh, or the liquid may form a film that blocks the mesh. This may cause S to adhere.

In this embodiment, the endless belt 23 is rotated such that the forward path side approaching the lower roller 21 is the side located in front of the lower roller 21 and the upper roller 22. That is, in the paper of FIG. 1(a), the endless belt 23 is rotated counterclockwise.

On the other hand, when the fan 11 is rotated by the fan motor 12, air from behind the fan 11 is sucked in and blown forward. As a result, a negative pressure is created behind the fan 11 inside the case 13, and outside air is sucked into the case 13 through the intake port 13b provided on the rear wall of the case 13. A flow of wind is generated through the outlet toward the spout 13a. When this wind passes through the mesh of the endless belt 23, the liquid S adhering to the irregularities of the mesh is blown away, and the liquid film blocking the mesh is burst, causing the liquid S to adhere to the endless belt 23. The liquid S becomes fine droplets, and the fine droplets are carried forward by the wind and are ejected from the spout 13a on the front surface of the case 13.

Thereby, the liquid S having a sterilizing effect and an antibacterial effect contained in the tank 10 can be made into fine droplets and sprayed into the external space of the device. Moreover, by using the spray device 1 of this embodiment in the room R, the entire environment in the room R can be easily cleaned by spraying the liquid S having sterilizing and antibacterial effects.

Furthermore, since the endless belt 23, which is partially immersed in the liquid S in the tank 10, is rotated, the liquid S is stirred together with an excessive amount of fired shell powder P by the rotation of the endless belt 23. Therefore, it is easy to maintain the saturation concentration of the liquid S.

Next, a spray device 2 according to a second embodiment of the present invention will be described with reference to FIG. 3. The spray device 2 includes a tank 30 that is open upward and that accommodates the liquid S, a lower roller 31 that is rotatably provided around an axis that extends in the horizontal direction within the tank 30, and a lower Two upper rollers 32 are provided above the roller 31 to be rotatable around an axis parallel to the lower roller 31, and a net-shaped endless ring is wound around the lower roller 31 and the two upper rollers 32. An endless belt 33, and a roller motor 34 that rotates one upper roller 32 to rotate the endless belt 33.

The spray device 2 also houses a fan 35 for passing air through the endless belt 33 and discharging it to the outside, a fan motor 36 for rotating the fan 35, and a tank 30. The case 37 is closed from above. Furthermore, although not shown, the spray device 2 includes an operation section for operating the spray device 2.

Although not shown, the tank 30 of the spray device 2 has an intake port penetrating the side wall near the upper end. This spray device 2 includes a lower roller 31, an upper roller 32, an endless belt 33, and a roller motor 34 in a tank 30. Note that casters may be attached to the bottom surface of the tank 30.

The lower roller 31 is provided in the center of the tank 30 near the lower end. The two upper rollers 32 are provided in the tank 30 at a higher position than the intake port, spaced apart in the horizontal direction, and at the same height. As shown in FIG. 3, the lower roller 31 and the two upper rollers 32 are provided so as to be located at each vertex of the inverted triangle, so that the endless belt 33 is wound along the edges of the inverted triangle. ing.

The fan 35 is provided above a portion of the endless belt 33 between the two upper rollers 32, and is rotated by a fan motor 36 to blow air upward.

Although not shown, the bottom wall of the case 37 that closes the opening at the upper end of the tank 30 is formed to have ventilation, and a spout is formed in the top wall. A fan 35 and a fan motor 36 are installed between the bottom wall and the top wall of the case 37.

Next, a method of using the spray device 2 of this embodiment and an air conditioning method using the spray device 2 will be explained. When using the spray device 2, first, the liquid S to which the baked seashell powder P has been added is stored in the tank 30 to a height between the lower roller 31 and the intake port provided on the side wall of the tank 30. .

Then, the upper roller 32 is rotated by the roller motor 34 to rotate the endless belt 33, and the fan 35 is rotated by the fan motor 36. Since the lower part of the endless belt 33 is immersed in the liquid S, as the endless belt 33 rotates, the liquid S may adhere to the irregularities in the mesh or form a film that blocks the mesh in a region above the surface of the liquid S. Liquid S may adhere to the surface.

When the fan 35 is rotated to start blowing air upward, the area between the fan 35 and the liquid level becomes negative pressure, so outside air is sucked in through the intake port provided on the side wall of the tank 30. The air sucked in from the intake port passes through the region between the lower roller 31 and the upper roller 32 on the endless belt 33 toward the center, and then rises to the region between the two upper rollers 32 on the endless belt 33. The air passes through the fan 35 in the case 37 and is emitted from the upper spout into the external space of the device. Then, as the air flow (wind) as described above passes through the endless belt 33, the liquid S adhering to the endless belt 33 becomes fine droplets, and the fine droplets are carried by the wind and spread to the case 37. It will be ejected from the nozzle on the top surface.

In this way, in the spraying device 2 of this embodiment as well, similarly to the spraying device 1, the liquid S having a sterilizing effect and an antibacterial effect stored in the tank 30 is made into fine droplets and sprayed to the outside. It is possible to achieve the same effects as above.

In addition, since the spray device 2 sprays fine droplets upward, it can be sprayed higher than when spraying in a horizontal direction. This makes it easy to spread the fine droplets throughout the room R.

Next, a spray device 3 according to a third embodiment of the present invention will be described with reference to FIG. 4. An air conditioning system A for air conditioning the entire building B includes a spray device 3 that sprays a liquid S to which baked seashell powder P has been added, and fine droplets sprayed from the spray device 3 to each room in the building B. It is equipped with an air conditioning duct D for sending air to R.

The spray device 3 of the air conditioning system A includes a tank 40 for containing the liquid S, a lower roller 41 rotatably provided around an axis extending in the horizontal direction within the tank 40, and a lower roller 41. an upper roller 42 rotatably provided above the lower roller 41 around an axis parallel to the lower roller 41; an endless belt 43 in the form of a net and an endless ring wound around the lower roller 41 and the upper roller 42; It includes a roller motor 44 that rotates the upper roller 42 and causes the endless belt 43 to revolve.

The spray device 3 also includes an air suction machine 45 that sucks outside air and sends it to the tank 40, and a blower that sends the air that is sent to the tank 40 by the air suction machine 45 and passed through the endless belt 43 to the air conditioning duct D. It is equipped with 46.

The tank 40 of the spraying device 3 has an intake port 40a communicating with an air suction device 45 at the top of the side wall, and an exhaust port 40b communicating with the blower 46 at the top of the side wall opposite to the intake port 40a. have. This spray device 3 includes a lower roller 41, an upper roller 42, and an endless belt 43 in a tank 40.

The lower roller 41 is provided near the lower end of the tank 40, and the upper roller 42 is provided near the upper end of the tank 40. The lower roller 41 and the upper roller 42 are provided so that the direction in which their axes extend is orthogonal to the direction in which the intake port 40a and the exhaust port 40b of the tank 40 are connected. Therefore, the surface of the endless belt 43 wound around the lower roller 41 and the upper roller 42 faces the intake port 40a and the exhaust port 40b.

The roller motor 44 is provided outside the tank 40, so that the liquid S contained in the tank 40 will not adhere to it.

Although not shown, the air suction device 45 and the blower 46 each include a fan and a fan motor for rotating the fan. Further, the air suction device 45 is provided with a filter for filtering outside air.

Next, a method of using the spray device 3 of this embodiment and an air conditioning method using the spray device 3 will be explained. When using the above air conditioning system A, first, liquid S containing baked seashell powder P is poured into the tank 40 of the spray device 3 to a height between the lower roller 41 and the intake port 40a and exhaust port 40b. Contain. In this state, the upper roller 42 is rotated by the roller motor 44 to cause the endless belt 43 to revolve. By rotating the endless belt 43, in the same manner as described above, the liquid S may adhere to the unevenness of the mesh, or the liquid may form a film that blocks the mesh, in the region above the liquid surface of the endless belt 43. S may be attached.

Subsequently, the air suction machine 45 and the blower 46 are operated to blow outside air through the air suction machine 45 into the tank 40 from the intake port 40a, and to blow the air inside the tank 40 from the exhaust port 40b through the blower 46. The air is blown into the air conditioning duct D. Inside the tank 40, air flows (wind) from the intake port 40a toward the exhaust port 40b, so the wind passes through the endless belt 43 provided between the intake port 40a and the exhaust port 40b.

As a result, the liquid S adhering to the endless belt 43 becomes fine droplets, and the fine droplets are carried by the wind and sent to the air conditioning duct D from the exhaust port 40b via the blower 46. Then, the wind containing minute droplets of the liquid S sent to the air conditioning duct D is released into each room R from near the ceiling of each room R provided on each floor of the building B.

As described above, according to the spraying device 3 (air conditioning system A) of this embodiment, the liquid S having a sterilizing and antibacterial effect stored in the tank 40 is supplied to each room R of the building B as a fine liquid. It can be sprayed in the form of droplets, and the same effects as described above can be achieved, and each room R in the building B can be air-conditioned.
