Abstract

PROBLEM TO BE SOLVED: To improve the reinforcing effect of the main body case and to reduce deformation and distortion by housing a circulation fan and a ventilation fan and integrating a casing for forming an air channel from a resin molded article. SOLUTION: A casing 1A for a circulation fan and a casing 1B for a ventilation fan are attached to a main body case 3 while being integrated from the resin molded article. The casing 1A for the circulation fan plays a role of circulating air in a bathroom while housing the circulation fan and forming the air channel as shown by an arrow. On the other hand, the casing 1B for the ventilation fan exhausts one part of air in the bathroom from an exhaust hole 2 to the outside while housing the ventilation fan and forming the air channel as shown by the arrow. Then, the casing 1 has structure integrated by the resin molded article, and the casing 1 is attached while being matched with the prescribed position of the main body case 3. Thus, assembly structure is simplified, man-hour for working is reduced and the reinforcing effect is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a casing, which is a component of a bathroom ventilation dryer capable of drying clothes by heating and drying the bathroom, and also enabling ventilation of the bathroom. is there.

[0002]

2. Description of the Related Art Conventionally, this type of bathroom ventilation dryer is shown in FIG.
As shown in the sectional view of the main part of FIG.
The heat is guided from a bathroom-side suction port 6 to a heater 8 via an air filter 7 by a circulation fan 5 provided therein, where it is heated and discharged into the bathroom from a bathroom-side discharge port 9. Further, a part of the air in the bathroom circulating in an intermediate portion between the circulation fan 5 and the heater 8 is exhausted to the outside from the exhaust port 2 by the ventilation fan 10, thereby heating the bathroom.
The clothes placed in the bathroom were dried while drying. In addition, bathroom ventilation can be performed by operating only the ventilation fan. However, as shown in FIGS. 5 and 6, the casing for accommodating the circulating fan and the ventilation fan must be separately installed, which requires a large number of man-hours, deforms the main body case,
The structure was easy to generate distortion.

FIG. 5 is a main assembly showing a state in which a circulating fan (not shown) and a ventilation fan (not shown) are respectively housed in a conventional main body case, and a casing for forming an air flow path is attached thereto. FIG. Case 11A for circulation fan
And the casing 11B for the ventilation fan are individually mounted.

FIG. 6 is a perspective view of a conventional case for a circulation fan and a case for a ventilation fan, wherein 11A is a case for a circulation fan and 11B is a case for a ventilation fan.

[0005]

In such a conventional configuration, the circulation fan and the ventilation fan must be separately mounted, and if they are separately mounted, the number of work steps is increased.
In addition, there is a problem that deformation and distortion of the main body case occur. The present invention solves such a problem,
An object of the present invention is to enhance the reinforcing effect of the main body case by reducing the separately mounted casing into an integrated structure, thereby reducing deformation and distortion.

[0006]

In order to solve this problem, according to the present invention, the case where the circulating fan and the ventilating fan are mounted and then the casing is separately mounted is integrated with a resin molded product. By adopting the structure, work can be performed at the same time, and the number of work steps can be reduced.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to this structure, a circulating fan and a ventilation fan are attached to a main body case, and then an integrated casing is attached by a resin molded product for accommodating each of them. Can be stored.

[0008]

An embodiment of the present invention will be described below.
Generally, as shown in FIG. 4 of the prior art, in a bathroom ventilation dryer, the air in the bathroom is circulated through an air filter 7 from a bathroom side suction port 6 by a circulation fan 5 provided in a main body case 3. , And is heated and discharged from the bathroom side discharge port 9 into the bathroom. Further, a part of the air in the bathroom circulating in the intermediate portion between the circulation fan 5 and the heater 8 is exhausted to the outside from the exhaust port 2 by the ventilation fan 10 to heat and dry the interior of the bathroom. While trying to dry the clothes placed in the bathroom. Further, if only the ventilation fan 10 is operated, the bathroom can be ventilated.

FIGS. 1 to 3 each show an embodiment of the present invention. FIG. 1 shows a state in which a casing for a circulation fan and a casing for a ventilation fan are integrally mounted on a main body case by a resin molded product, and arrows indicate air flow paths. Reference numeral 1A is a casing for a circulation fan that houses a circulation fan (not shown) and forms an air flow path as indicated by an arrow, and has a role of circulating air in the bathroom. On the other hand, 1B is a casing for a ventilation fan which accommodates a ventilation fan (not shown) and forms an air flow path as shown by an arrow, and discharges a part of the air in the bathroom to the outside through an exhaust port 2.

The casing 1 of the present invention has a structure integrally formed of a resin molded product. The casing 1 is fitted to a predetermined position of the main body case 3 and attached. This structure simplifies the assembling structure, reduces the number of work steps, enhances the reinforcing effect of the integration, and improves the integrated casing as compared with the case where the fans are separately housed in the past. By mounting the main body case and the main body case in a contact state, the reinforcing effect is further increased, and deformation and distortion of the main body case can be reduced.

FIG. 2 is a perspective view before the integrated casing 1 is attached to the main body case 3. Circulating fan case
The structure in which the casing 1A and the casing 1B for the ventilation fan are integrated and attached to the main body case 3 makes it easy to attach two fans (not shown) at the same time.
The effect of reinforcing the main body case by integrating the casing is enhanced, and deformation and distortion can be reduced.

FIG. 3 is an exploded perspective view of the integrated casing for explanation, wherein 1A is a casing for a circulation fan and 1B is a casing for a ventilation fan. Circulation case
In the sing 1A, a curved portion 4 for guiding is provided at a corner portion for smooth air flow.

[0013]

As described above, according to the present invention, the casing of the circulation fan and the ventilation fan used in the bathroom ventilation dryer can be installed at the same time, so that the workability is improved and the fan is housed. Reinforcement is increased by integrating and integrating the respective casings, and deformation of the body case,
Distortion hardly occurs.
