DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom ventilation dryer which is mounted on a ceiling of a bathroom and is used for ventilation and drying of the bathroom, and also for drying clothes suspended in the bathroom.

[0002]

2. Description of the Related Art FIGS. 3 and 4 show a conventional bathroom ventilation dryer. FIG. 3 is a diagram showing a state in which a conventional bathroom ventilation dryer is mounted on a ceiling of a unit bath. FIG.
FIG. 4 is a diagram showing a state in which a ventilation drying unit is attached to the bathroom ventilation dryer of FIG. 3.

[0003] As shown in FIG. 3, the bathroom ventilation dryer 35 is mounted on an upper part of a ceiling 41 of the unit bath 31. The bathroom ventilation dryer 35 has a box-shaped casing 36 whose lower surface is open. This casing 3
A fan 37 and a heat exchanger ventilation 39 are incorporated in 6. The fan 37 alone can be operated to exhaust the humid air in the bathroom, or hot water can be passed through the heat exchanger 39 to send dry hot air into the bathroom. By the way, the ventilation duct 2 is provided on the casing 36 of the bathroom ventilation dryer 35.
1 is connected to the bathroom ceiling 4 next to the bathroom ventilation dryer.
The operator opens the working port 43 provided in 1 and from here the worker puts his hand or head into the ceiling to work.

[0004] The fan 37 of the bathroom ventilation dryer 35 of FIG.
The heat exchanger 39 and the like are configured as a ventilation drying unit that can be removed from the casing 36. FIG.
Shows a state in which the ventilation drying unit 19 is about to be attached to the casing 1 from below. The lower surface 7 of the casing 1 is open (a lid can be attached), and a means for suspending the ventilation drying unit 19 such as the hook 9 is provided inside the casing 1. After hanging the ventilation drying unit 19 on the hook 9 and further connecting wires and pipes, the bathroom ventilation dryer 35 can be operated.

[0005]

However, in the conventional bathroom ventilation dryer, it was necessary to open the above-mentioned working port on the ceiling of the bathroom in addition to the mounting portion of the bathroom ventilation dryer.
Therefore, it was necessary to make such an opening in the bathroom ceiling in advance. Alternatively, when installing a bathroom ventilation dryer in a conventional bathroom having no such opening, it was necessary to perform two openings on the ceiling. This opening construction has problems in that it blocks moisture and the appearance of the lid of the working opening is poor, and in some cases, gives up the installation of the bathroom ventilation dryer itself.

An object of the present invention is to provide a bathroom ventilation dryer which can be installed (maintained) without providing a working port other than a bathroom ventilation dryer installation portion.

[0007]

In order to solve the above-mentioned problems, a bathroom ventilation dryer of the present invention is mounted on a ceiling of a bathroom and has an open lower surface, and is housed in the casing from the lower surface side of the casing. And a ventilation drying unit including a fan or the like; a connection port such as a ventilation duct is provided on a side surface and / or an upper surface of the casing; An openable work port is provided, and this work port is provided with a lid that can be attached and detached from the bottom of the casing. Can be put out of the ceiling of the bathroom for work.

[0008]

When the bathroom ventilation dryer of the present invention is installed on the ceiling of a bathroom, first, a casing is attached to the ceiling. Next, the lid of the working port of the casing is removed, and the worker puts his / her hand or head on the ceiling, attaches a ventilation duct to the connecting port of the casing, and passes piping, wiring, etc. through the casing.
After that, the work opening is covered, and the ventilation drying unit is housed in the casing from under the casing.

The ventilation and drying unit of the present invention does not need to be a unit that separately performs both ventilation and drying. Either of them may be performed. Further, it may have another function (for example, air conditioning in a bathroom). As what is connected to the casing or passes through the casing, in addition to the above-mentioned ventilation duct, for example, hot water piping,
There may be a refrigerant pipe, an electric wire and the like.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a casing of a bathroom ventilation dryer according to one embodiment of the present invention. The casing 1 of the bathroom ventilation dryer has a box-like shape whose lower surface 7 is open. A circular connection port 3 to which the ventilation duct 21 is connected is provided on a side surface of the casing 1. On the side of this casing, beside the part with the connection port 3,
The working port 5 is open. When attaching the ventilation duct 21 to the connection port 3, as shown in the figure, put a hand or a head into the ceiling from the work port 5, and hold the duct 21 and visually connect to the connection port 3. I do. The connection between the two is made by a method such as winding an adhesive tape.

In addition to the ventilation duct 21, hot water piping and electric wires are passed through the bathroom ventilation dryer casing 1. The hot water pipe may be a combination of a row / return water pipe and a control signal line (CD pipe) or the like. Reference numeral 8 in the figure denotes a hole through which the hot water pipe passes.

FIG. 2 is a perspective view showing a state in which the ventilation drying unit is incorporated into the casing of the bathroom ventilation dryer of FIG. 1 from below. At the working opening of the casing 1, a lid 11 is provided.
Are attached from the inside of the casing 1. In this state, the ventilation drying unit 19 is put into the casing 1 from below, and the ventilation drying unit 19 is hung on the hook 9. Further, after connecting the hot water pipe 23 and the wiring to the ventilation drying unit, a breathable lid (not shown) is attached to the open lower surface 7 of the casing 1, and the installation of the bathroom ventilation dryer is completed. The hot water pipe 23 and the hole 8 passing therethrough may be sealed with a bushing material or the like.

Although not shown in FIGS. 1 and 2, a work opening is also provided on the upper surface of the bathroom ventilation dryer casing 1, from which the worker puts his head out of the ceiling and looks at the ventilation duct and piping. However, those connection operations can be performed.

[0014]

As is clear from the above description, the bathroom ventilation dryer of the present invention can be installed without opening a ceiling or a work port for installation work and maintenance separately from the bathroom ventilation dryer installation part. Therefore, labor for installation work can be reduced. In addition, it can be installed in a conventional bathroom having a small opening portion of the ceiling without any problem.
