BACKGROUND OF THE INVENTION
The present invention relates to a ventilation fan unit for a bathroom heater installed outdoors, and in particular, a ventilation fan capable of efficiently drawing out hot water tubes and electric wires connected to a bathroom heater installed in a bathroom. Regarding the unit.
[0002]
[Prior art]
A bathroom heating dryer that heats the interior of the bathroom by blowing hot air into the bathroom using the heat of the hot water supplied from the hot water heating heat source is usually a wall on the bathroom side of the outer wall that forms the bathroom. In the state where it is installed, the humid air in the bathroom is exhausted to the outside through the ventilation hole formed in the installation area, and the ventilation fan is installed in the bathroom heating dryer installed in the bathroom There are types that are installed and types in which ventilation fan units are installed separately outdoors.
[0003]
By the way, in such a bathroom heater / dryer, a hot water tube includes a heat exchanger mounted in a bathroom heater / dryer installed in a bathroom and an outdoor hot water pipe connected to a hot water heater / heat source installed outdoors. Normally, the hot water tube connected to the bathroom heater / dryer is pulled out to the outside through the ventilation hole that penetrates the outer wall. In the type of bathroom heater / dryer to be installed, the ventilation fan unit is usually installed at a position corresponding to the ventilation hole on the outer wall, so the hot water tubes and electric wires drawn out through the ventilation hole are temporarily connected to the ventilation fan unit. After being introduced to, it is designed to be pulled out from the ventilation fan unit.
[0004]
As shown in FIG. 8, such a ventilation fan unit includes a plate-shaped ventilation adapter 51 attached to the wall surface of the outer wall so as to correspond to the formation position of the ventilation hole that penetrates the outer wall forming the bathroom, A ventilation fan 52 screwed to the ventilation adapter 51 and a fan cover 54 screwed to the ventilation adapter 51 so as to cover the ventilation fan 52 are configured. The ventilation adapter 51 has a ventilation hole. An opening 51a to be opened is formed.
[0005]
As shown in FIG. 9, the ventilation fan 52 is provided with a suction port portion 52 a surrounding the opening 51 a formed in the ventilation adapter 51 in a state of being screwed to the ventilation adapter 51. The rubber bushing 53 which can form the tube outlet 53a and the electric wire outlet 53b for letting two hot water tubes and electric wires pass to both the left and right sides is attached to the 52a, As shown in FIG. 8, the fan cover 54 is cut to form hot water tubes and electrical wire outlets at positions corresponding to the left and right rubber bushes 53 attached to the suction port 52 a of the ventilation fan 52. A possible portion 54a is formed.
[0006]
To install the ventilation fan unit 50 configured as described above, first, the ventilation adapter 51 is screwed to the wall surface of the outer wall so that the opening 51a corresponds to the ventilation hole penetrating the outer wall. Subsequently, a tube outlet 53a and an electric wire outlet 53b for drawing out the hot water tube and electric wires were formed in either one of the rubber bushes 53 mounted on the left and right sides of the suction port portion 52a of the ventilation fan 52, respectively. Thereafter, the two hot water tubes and electric wires drawn out through the ventilation hole are drawn out from the inside of the suction port portion 52a of the ventilation fan 52 through the tube outlet 53a and the electric wire outlet 53b formed in the rubber bush 53. In this state, the ventilation fan 52 is screwed to a predetermined position of the ventilation adapter 51 as shown in FIG.
[0007]
Then, the ventilation cover 51 is configured so that the ventilation cover 52 covers the fan cover 54 formed with the outlet by cutting the excisable portion 54a corresponding to the rubber bush 53 from which the hot water tube HC and the electric wires EW are drawn. When the screw is fixed to the position, the ventilation fan unit 50 is installed on the outer wall surface in a state where the hot water tube HC and the electric wires EW are pulled out from the fan cover 54.
[0008]
[Problems to be solved by the invention]
However, as described above, after the tube outlet 53a and the wire outlet 53b are formed in the rubber bush 53 attached to the suction port 52a of the ventilation fan 52, the hot water tube is passed through the tube outlet 53a and the wire outlet 53b. In the ventilation fan unit 50 in which the HC and the electric wires EW are drawn out, the operation of passing the hot water tube HC and the electric wires EW through the tube outlet 53a and the electric wire outlet 53b must be performed with the ventilation fan unit 50 held. Moreover, since the ventilation fan 52 must be screwed to the ventilation adapter 51 in a state where the hot water tube HC having a certain degree of rigidity is pulled out together with the electric wires EW, the installation work of the ventilation fan unit 50 is performed smoothly. There is a problem that can not be.
[0009]
In addition, when the hot water tube HC and the electric wires EW are once pulled out from either the left or right side of the ventilation fan 52, the hot water tube is removed from the rubber bush 53 in the case where the pulling direction has to be changed for some reason. After extracting the HC and the electric wires EW, the tube outlet 53a and the electric wire outlet 53b are formed in the opposite rubber bush 53, and the tube outlet 53a and the electric wire outlet formed in the unused rubber bush 53 are formed. There is a problem that laborious work such as closing 53b with a putty or the like must be performed, and the drawing direction of the hot water tube HC and the electric wires EW cannot be easily changed.
[0010]
Therefore, an object of the present invention is to provide a ventilation fan unit that can easily and efficiently perform a drawing operation of a hot water tube and electric wires connected to a bathroom heater installed in the bathroom and a change in the drawing direction. It is in.
[0011]
[Means for solving the problems and effects thereof]
In order to solve the above problems, the invention according to claim 1 is provided with a ventilation adapter attached to the wall surface of the outer wall so as to correspond to a ventilation hole penetrating the outer wall forming the bathroom, and screwed to the ventilation adapter. And a fan cover screwed to the ventilation adapter so as to cover the ventilation fan, the ventilation adapter includes an opening corresponding to the through hole, and the opening And a ventilation fan mounting portion projecting outward so as to surround, and the mounting portion is formed with a notch portion for drawing out the hot water tube and electric wires, and the notch portion is flexible. The present invention provides a ventilation fan unit for a bathroom heater, which is preliminarily fitted with a sealing material having properties and elasticity.
[0012]
As described above, this ventilation fan unit has a ventilation adapter mounting portion protruding outward so as to surround the opening portion in the ventilation adapter, and the cutout portion formed in this mounting portion has flexibility and elasticity. Since the configuration in which the sealing material is previously installed is adopted, the hot water tube drawn out from the through hole and the opening after attaching the ventilation adapter to the outer wall so that the ventilation hole and the opening formed in the outer wall correspond to each other And when the wires are pressed against the sealing material and pulled out of the mounting part of the ventilation fan, the hot water tube and the electric wire part in the sealing material having flexibility and elasticity are recessed and the hot water tube and the electric wires are attached to the mounting part. Is housed in the notch. In this state, when the ventilation fan is screwed to the mounting part, the notch with the sealing material is completely closed by the ventilation fan, and the hot water tube and the electric wires are sealed with the sealing material. Electric wires are pulled out from the mounting portion.
[0013]
Therefore, unlike the conventional ventilation fan unit, the operation of forming the tube outlet and the electric wire outlet for drawing out the hot water tube and the electric wires in the rubber bush attached to the suction port of the ventilation fan becomes unnecessary. Unlike a conventional ventilation fan unit that requires a ventilation fan to be screwed to a ventilation adapter in a state where a hot water tube with a certain degree of rigidity is pulled out from the suction port together with electric wires, the ventilation fan and the hot water tube are independent. Since it can be handled in a state, the work of attaching the ventilation fan to the ventilation adapter can be performed smoothly.
[0014]
Further, as in the ventilation fan unit of the invention according to claim 2, in the state where the ventilation adapter is attached to the wall surface of the outer wall, the notch portions are respectively formed on the left and right sides and the lower side of the attachment portion. Then, since the hot water tube can be pulled out in any three directions on the left and right sides and the lower side of the ventilation fan unit, it is possible to perform construction more suitable for the situation at the site. In particular, since the hot water tube can be pulled out not only on the left and right sides of the ventilation fan unit but also on the lower side, it is possible to facilitate and simplify the construction on site.
[0015]
Further, as in the ventilation fan unit of the invention according to claim 3, the fan cover is formed with a resectable portion for forming the hot water tube and an outlet for the electric wires, If there are ribs protruding outward, the burrs and cut surfaces that occur when the excisable part is excised are concealed by the ribs, so the appearance of the ventilation fan unit is impaired. In addition, the presence of ribs also has the effect of making it difficult for rainwater and the like to enter the inside of the fan cover from the hot water tube and the wire outlet.
[0016]
