Abstract

PURPOSE:To prevent assembling errors of a drive roller and the penetration of water inside by changing the diameter of an axle of a shaft support plate mounted to both end openings of a cylinder for a drive roller form that of a connection shaft of a connection end plate. CONSTITUTION:A hollow axle 48 is installed to a shaft support end plate so that it may project, thereby forming a connection shaft 50 which forms an engagement recessed part fitted in and connected with forms an engagement recessed part fitted in and connected with an output shaft 41. The outside diameter 'a' of the pickle 48 thus formed is smaller than the outside diameter 'b' of the connection shaft 50. The inside diameters of a shaft support bore of a support wall plate 32 and a shaft support bored section 40 of a motor housing case 39 are formed so that they may support each shaft 48 and 50 steadily. A small- sized drain water hole is formed on the end of the pickle 48. When assembling a drive roller 34, if an attempt is made to mount the shaft support end plate 46 and the connection end plate alone with both ends of a cylinder 45, shaft support to the shaft support hole is impossible to be carried out while their mounting to the output shaft 41 is also impossible to be carried out, which makes it possible to detect any failure of the drive roller 34. The drive roller, even when assembled in a normal manner, can not be supported with the support wall plate 32 nor mounted with the output shaft 41 only except for a specified direction, thereby preventing the generation of assembling error.

Description

Detailed description of the invention (a) Industrial application field The present invention rotates a belt-shaped filter whose lower part is immersed in water in an aquarium, and allows air to pass through the belt-shaped filter that has absorbed water, thereby producing humidified air or Related to air conditioners that produce cold air.

(b) Prior art As a technology prior to the present invention, the sky described in Japanese Patent Publication No. 13346/1983 is a technique prior to the present invention. The air conditioner is equipped with a belt-shaped filter installed between a drive roller driven by an electric motor and a driven roller located in a water tank, and the belt-shaped filter is rotated to extract water-containing bells (humidifiers). The drive roller is made of a cylindrical body, has a pivot shaft protruding from one end, and a recess into which the output shaft of the electric motor can be inserted and moved.

Since the drive roller is cylindrical, Table 1kj applies to water.
Since the filters only get wet, there are no hygienic problems, but on the other hand, the outer diameter cannot be increased, and the interval between the belt-shaped filters cannot be increased, and the belt-shaped filters may come into contact with each other due to their bending.

To solve this problem, in order to increase the external shape of the drive roller, the drive roller is formed into a cylindrical body, and the openings at both ends are closed to form a pivot and a connecting part, but water does not enter the cylindrical body. If it gets in, it becomes a source of mold and bacteria, so it is necessary to have a structure that allows water to drain out, but if the structure allows water to drain to the motor side, problems will occur in terms of electrical insulation.

In addition, end plates are attached to the openings at both ends of the cylindrical body.
If there is a misassembly of the end plates to be attached, it is necessary to confirm the misassembly before the Y4 aircraft is completely assembled, or it is necessary to create a structure that prevents misassembly.

(c) Problems to be Solved by the Invention The technical object of the present invention is to provide an air conditioner in which a belt-shaped filter can be rotated in a circular motion, which is sanitary and easy to assemble.

(d) Means for Solving the Problems The present invention includes a frame body in which an air blower is housed and a ventilation path from an air intake port to an air outlet, a water tank disposed at the lower part of the frame body, and a water tank disposed at the upper part of the frame body. The drive roller is equipped with a drive roller driven by an electric motor installed in the water tank, a support rod disposed in the water tank, and an aeration water-containing strip filter installed across the ventilation path between the drive roller and the support rod. The roller is attached to a cylindrical body with openings at both ends on which the strip filter is applied, a shaft support end plate that forms a pivot, and is attached to an opening at one end of the cylindrical body, and an opening at the other end of the cylindrical body, and is fitted to the output shaft of the motor. The connecting end plate has a connecting shaft formed with a mating recess, and the external shape of the connecting shaft is larger than that of the pivot, and the shaft supporting end plate has a first means for forming a pore that communicates with the inside of the cylinder. It is something that solves problems.

Further, the present invention includes a frame body in which an air blower is housed and a ventilation path from an air intake port to an air outlet, a water tank disposed at the bottom of the frame body, and a drive driven by an electric motor disposed at the top of the frame body. The belt-like filter is provided with a roller, a support rod disposed in the water tank, and an aerated water-containing belt-like filter installed between the drive roller and the support rod so as to provide an air passage. It consists of a cylindrical body with openings at both ends, and an end plate that is attached to the openings at both ends of the cylindrical body and forms a pivot that forms a fitting recess for the output shaft of the motor. The problem is solved by a second means of forming a through hole communicating with the.

(E) Effect The present invention provides the first means, so that even if an attempt is made to attach the shaft support end plate with the pores formed to the output shaft of the electric motor, the connection cannot be made because the shaft does not have a fitting recess, and the connection end plate cannot be connected to the shaft. Even if you try to support it on the shaft support part, the connecting shaft is thicker than the pivot and cannot be supported.

In the second means, the same end plate is attached to the cylinder,
Both the output shaft and the shaft support part of the electric motor can be connected and supported, but when the output shaft is fitted into the fitting recess, the through hole is twisted and the water inside the cylinder is transferred from the through hole to the electric motor. Water is not drained to the y1 side.

A pair of support wall plates 32 are formed on both inner surfaces of the intake port 8 of the main frame body 2, and a support plate 33 inserted into the water tank 4 through the insertion port 28 is provided at the lower edge of the support wall plate 32.
is being extended. The lower end of the support plate 33 is located close to the bottom of the water tank 4.

A shaft support hole is formed in the upper part of the support wall plate 32, and the drive roller 34 is supported in the shaft support hole. A fixing rod 35 is fixedly disposed between the lower ends of the support plate 33. A belt-shaped filter 5 is installed between the drive port 234 and the fixed rod 35. A filter contact prevention body 36 is formed in the vertically intermediate portion of the support wall plate 32 . The filter contact member body 36 includes a contact prevention portion 37 whose surface facing the intake port 8 is a curved surface, and a joining guide portion 38 that hangs down. The contact prevention part 37 prevents the belt-shaped filter 5 from being bent inward due to the wind pressure of the air sucked in from the intake port 8, and does not prevent the belt-shaped filter 5 from moving (rotating).

A motor storage case 39 in which the drive motor 22 is housed is formed on the outer surface of one upper shaft support hole portion of the support wall plate 32 . The motor storage case 39 has a shaft support hole g[ao that fits into the shaft support hole, and the drive motor 22 is installed in the motor storage case 3 so that the output shaft 41 is located at the center of the shaft support hole 40.
It is fixed at 9.

The drive roller 34 is composed of a cylinder body 45 with openings at both ends, a shaft support end plate 46 fitted into an opening at one end of the cylinder body 45, and a connecting end plate 47 fitted into an opening at the other end of the cylinder body 45.

A hollow pivot 48 is provided protruding from the shaft support end plate 46, and the connecting end plate 4
7 is formed with a connecting shaft 50 having a fitting recess 49 for fittingly connecting to the output shaft 41. The outer diameter of the pivot shaft 48 is smaller than the outer diameter of the connecting shaft 50, and the inner diameter of the shaft support hole of the support wall plate 32 and the shaft support hole 40 of the motor storage case 39 are such that each shaft 48. It is formed to a size that can support it. A drainage hole 51 is formed at the end of the pivot 48 .

When assembling the drive roller 34, only the shaft supporting end plates 46 are attached to both ends of the cylindrical body 45, or 31! If only the end plate is attached, the drive roller 34 can be found to be defective because it cannot be supported in the shaft support hole and cannot be attached to the output shaft 41.

Even if the drive roller 34 is properly assembled, the shaft support to the support wall plate 32 and the connection to the output shaft 41 can only be mounted in a specified direction, thereby preventing incorrect assembly. Even if the assembly of the cylindrical body 45, the shaft end plate 46, and the connecting end plate 47 is not completely watertight, water that has entered the cylindrical body 45 can be drained from the drain hole 51 of the shaft end plate 46, and the drive motor 2
It does not penetrate into the second side and is good for electrical insulation.

Three types of protrusions 52, 53, and 54 having different heights are formed on the outer surface of the cylindrical body 45 of the drive roller 34 in the axial direction. Projection 5
2.53.54, as shown in Figures 8 and 9, the highest protrusion 52 is formed at a position facing 180 degrees, and the next highest protrusion 53 is formed at a position shifted by 90 degrees from the protrusion 52. However, the lowest protrusion 54 is formed at a position shifted by 45 degrees from the protrusion 52 and 53. By making the heights of the protrusions 52, 53, and 54 different, they are better caught on the belt-shaped filter 5, preventing slippage, and the belt-shaped filter 5 is rotated clockwise by the drive roller 34 (as shown in FIG. 1). can be rotated one transport revolution. 7 is a front view, FIG. 8 is a right side view, and FIG. 9 is a left side view, showing the drive roller 34.

The fixing rod 35 is formed separately from the support plate 33.

The fixing rod 35 has a U-shaped cross section, and has end walls 56 with V-shaped notches 55 formed at both ends thereof. By forming the notch 55, the fixing rod 35 has some elasticity to bend inward. A plurality of drainage holes 5 are provided at the bottom of the fixed rod 35.
7 is formed. Claw pieces 59 that engage with the engagement holes 58 of the support plate 33 are formed on both edges of both ends of the fixing rod 35 . After expanding outward using the elasticity of the support plate 33, the claw pieces 59 of the fixing rod 35 are engaged with the engagement holes 58. Fixed rod 35
By attaching the support plate 33 to the support plate 33, it is possible to prevent the support plate 33 from expanding outward. The claw pieces 59 are formed with claws facing outward or inward and engaged with the engagement holes 58, so that even if an upward pulling force is applied to the fixing rod 35, the claw pieces 59
No force is applied to bend and remove the fixing rod 35, and the fixing rod 35 does not come off during use.

The belt-shaped filter 5 is mounted between the drive roller 34 and the fixed rod 35. When the drive motor 22 is driven, the inner surface of the belt-shaped filter 5 is pulled up by the drive roller 34 and sent to the outside, so that the belt-shaped filter 5 slides on the curved outer surface of the fixed rod 35. be. As shown in FIG. 2, when the lid body 6 is removed from the main frame body 2, the fixing rod 3
The water W accumulated in the tank 5 can be drained smoothly from the drain hole 57. Rod 35 fixes the lower part of the belt-shaped filter
By supporting the support plate 33 with the support wall plate 3, the structure is simplified compared to the conventional support using a driven roller, and the degree of freedom in designing the fixed rod 35 is also improved.
The fixing rod 3 is formed separately from the support plate 33 which is formed separately from the support plate 33.
5 can also be integrally molded.

In addition, since the cold air Ja1 has high humidity and comes into contact with the inner surface of the ventilation passage, and the belt-shaped filter 5 and water tank 4 are constantly exposed to water, they become a source of germs and mold, and also generate strange odors. Therefore, when it is desirable to provide a disinfectant, an anti-spicy agent, or an aromatic agent, by forming a storage section for six agents in the entire or part of the groove of the fixing rod 35, it is possible to efficiently add and replace the agent. It can be done. The storage part also has a fixed rod 3
Since the belt-shaped filter 5 slides around the moving center of the belt-shaped filter 5, the structure can be simplified.
can be added efficiently.

In each of the above descriptions, the main frame 2, lid 6, water tank 4, drive roller 34, fixing rod 35, etc. are best molded with synthetic resin as a matter of design change, and water W and humidity are high. It is best to use moisture-resistant and water-resistant materials since they will be used in various conditions.

The optimal material for the belt-shaped filter 5 is a material with low ventilation resistance, good water absorption, strong tensile strength, and little sag.In this structure, 30% acrylic deodorizing fiber, 30% polyester deodorizing fiber, and nylon are used. A nonwoven fabric made of 30% is used. In order to facilitate replacement, cleaning, and assembly during production, the belt-shaped filter 5 is formed with a joint so that it can be moved in and out of the belt, and has a flat plate shape with ends and an endless annular shape. The joints are connected using a simple joining means called Velcro. II! The easy-to-join means consists of a hook plate 62 having a large number of hook bodies 61 planted therein, and a hook receiving plate 64 having a large number of hook receivers 63 on which the hook bodies 61 are hooked. The hooking body 61 is as shown in FIG.
A part of the fibers planted in a loop shape is cut to form an inverted J shape, and the hook receiver 63 is formed of the fibers planted in a loop shape or a nonwoven fabric. The hook body 61 is hooked on the hook receiver 63 by its own elastic deformation, and a large number of them engage with each other, resulting in a surface joint, and the force parallel to the plane and the engagement in the direction of pulling the belt-shaped filter 5 are strong. The hook 61 can be deformed and separated by a force perpendicular to the surface or a force in the peeling direction. The hook plate material 62 and the hook receiving plate material 64 are sewn to the joint portion of the belt-shaped filter 5.

In addition, as a means of changing the color of the hook plate 62 and the hook receiving plate 64, which are given different colors, the colors of the hook body 61 and the hook receiving body 63 are changed.

By distinguishing the hook plate material 62 and the hook receiving plate material 64 by color, it is possible to perform the work without fail even when the two are separated when sewing them to the joint portion of the belt-shaped filter 5. When installing between the drive roller 34 and the fixed rod 35, as shown in FIGS. 13 and 15, the hook plate material 62 is placed on the inside and the hook receiving plate material 64 is placed on the outside.

By joining in this way, even if it is caught on the drive roller 34, it is difficult to apply force to remove the joint, and even if the hook plate material 62 covers the belt-shaped filter 5 itself during joining, the hook plate material 62 will not be able to be attached to the belt-shaped filter. Since 5 is a non-woven fabric, it engages with the drive roller 34 with its end raised.
Or, it will not get caught on the fixed rod 35. From the viewpoint of workability, the joining is carried out using the flat part of the joining guide part 38 of the filter contact prevention body 36 as a stand.
As shown in FIG. 14, the hook receiving plate material 64 should be placed on the inside, and the surfaces should be properly aligned. By doing so, it is caught on the drive roller 34 or the fixed rod 35, and the hook receiving plate material 64 and the hook plate material 6
2 can be peeled off and the joint will come off.By making it possible to distinguish the hook receiving plate material 64 and the hook plate material 62 by color, it is possible to distinguish between the hook plate material 64 and the hook plate material 62, so that it is possible to distinguish between the use mark, the inner surface of the lid body 6, or the joint. By displaying (indication) explaining the joining in color on the guide portion 38 or the like, the user can perform proper joining without fail even if he or she does not understand the structure.

FIG. 16 shows another structure of the drive roller 34, and the other parts are the same as the above-mentioned structure, and the explanation of the drawings will be omitted.

In the structure shown in FIG. 16, the connecting end plates 47 of the above-described structure are fitted to both ends of the cylindrical body 34. Therefore, the number of parts can be reduced without requiring the shaft support end plate 46 having a separate structure. Since the connecting end plates 47 having fitting recesses 49 into which the output shaft 41 of the drive motor 22 fits are attached to both ends of the cylindrical body 34, there is no loading force direction of the drive roller 34 during assembly, and assembly efficiency is improved. improves. A through hole 70 for draining water that has entered the cylindrical body 34 is formed in the back wall of the fitting recess 49.
By forming the through hole 70 in the back wall of the fitting recess 49, the through hole 70 is closed by fitting the output shaft 41 into the fitting recess 49. Therefore, water that has entered the cylindrical body 34 is removed from the drive motor 2.
The connecting end plate 47 having the through hole 70 can be attached to both ends of the cylindrical body 34 without draining water to the output shaft 41 side of the cylinder 34.

(g) Effects of the invention The present invention provides a shaft in which pores are formed by making the outer diameters of the shaft of the shaft supporting end plate and the connecting shaft of the connecting end plate different, which are attached to the openings at both ends of the cylindrical body of the drive roller. In addition, a through hole is formed in the back wall of the fitting recess formed in the pivot of the end plate that is attached to the openings at both ends of the cylinder of the drive roller. The through hole is closed 11 by fitting the shaft into the fitting recess.

With the above means, incorrect assembly of the drive roller is prevented, water is prevented from entering the electric motor, and the belt-shaped filter can be rotated smoothly for a long period of time.
