The bathroom ventilation drying apparatus 1 which concerns on embodiment is attached to the ceiling of bathroom BR.
As illustrated in FIG. 1, a bathroom ventilation drying apparatus 1 a according to an example of one-room ventilation according to the embodiment sucks air from a bathroom BR and blows it out toward the bathroom BR via a heater. Alternatively, the bathroom ventilation drying apparatus 1a sucks in air in the bathroom BR and discharges at least a part of the sucked air to the outside through the duct D1 (the detailed structure is not shown).
For example, a bathroom SR is provided adjacent to the bathroom BR, and a remote controller RC is provided on the wall surface of the bathroom SR. The bathroom ventilation drying apparatus 1 is operated by the remote controller RC.

  As shown in FIG. 2, the bathroom ventilation drying apparatus 1b according to an example of the multi-room ventilation of the embodiment is connected to a room (for example, a bathroom SR) other than the bathroom BR through a duct D2 in addition to the bathroom BR. The bathroom ventilation drying apparatus 1b sucks in air in the bathroom BR and air in the bathroom SR, and discharges the air through the duct D1 to the outside. Alternatively, the bathroom ventilation drying apparatus 1b can also suck in the air in the bathroom BR and blow it out toward the bathroom BR via a heater (the detailed structure is not shown).

Further, hereinafter, the direction in which the bathroom ventilation drying apparatus 1 is viewed from the bathroom BR is referred to as “up”, and the direction opposite to “up” is referred to as “down”.

Next, the structure of the bathroom ventilation drying apparatus 1a and the bathroom ventilation drying apparatus 1b will be described with reference to FIGS.
Drawing 3 is a sectional view showing bathroom ventilation drying device 1 concerning an example of one room ventilation of an embodiment.
Drawing 4 is a sectional view showing bathroom ventilation drying device 1 concerning an example of multi-room ventilation of an embodiment.
For convenience of explanation, illustration of functions related to ventilation is omitted.

As shown in FIG. 3, the bathroom ventilation drying apparatus 1 a includes a common module 10 and a casing 101.
The common module 10 includes a panel 103, a fan 105, a rail 107, a scroll 109, a filter 120, an intake port 131, and a ventilation port 133.

The casing 101 is provided in an opening formed in the ceiling C of the bathroom BR.
The air inlet 131 is formed on the lower surface of the casing 101.
The ventilation port 133 is formed on the side surface of the casing 101. The ventilation port 133 is connected to the duct D1 shown in FIG. 1 and connected to the outdoors.
The scroll 109 is provided inside the casing 101. One end of the internal space of the scroll 109 is connected to the intake port 131, and the other end is connected to the ventilation port 133.
The panel 103 is provided below the casing 101 and covers the scroll 109 from below.

  The fan 105 is provided inside the scroll 109. The fan 105 is, for example, a sirocco fan in which a plurality of blades are arranged in the circumferential direction. When the fan 105 operates, the air in the bathroom BR flows from the outer periphery of the panel 103 to the air inlet 131 through the gap between the casing 101 and the panel 103, as represented by the arrow in FIG. The air that has flowed into the air inlet 131 is sucked from the lower side (second direction) toward the upper side (first direction), and is exhausted from the ventilation port 133 through the inside of the scroll 109.

The rail 107 is provided in the air inlet 131 of the casing 101. The rail 107 is configured to hold the filter 120.
The intake port 131 is covered with a filter 120. The air that flows from the gap between the casing 101 and the panel 103 passes through the filter 120 upward.

As shown in FIG. 4, the bathroom ventilation drying apparatus 1 b has a shutter 113 and an air inlet 135 in addition to the common module 10 and the casing 101.
The air inlet 135 is connected to the duct D2 illustrated in FIG. 2 and is connected to a room other than the bathroom BR. Further, in the bathroom ventilation drying apparatus 1b, a gap G is formed between the casing 101 and the scroll 109 on the side where the air inlet 135 is provided. The intake port 135 is connected to the intake port 131, the internal space of the scroll 109, and the ventilation port 133 through the gap G.

  A shutter 113 is provided on the air path that connects the intake port 135 and the ventilation port 133, and between the intake port 131 and the intake port 135 (gap G). The shutter 113 is configured to be rotatable. By rotating the shutter 113, it is possible to switch between shielding and opening the air passage that connects the air inlet 135 and the vent 133.

For example, by operating the fan 105 with the shutter 113 opened, the air in the bathroom BR and the air in another room can be ventilated.
Alternatively, by operating the fan 105 with the shutter 113 shielded, only the air in the bathroom BR can be discharged to the outdoors. By blocking only a part of the gap G by the shutter 113, it is possible to increase the flow rate of air flowing from the bathroom BR while suppressing the flow rate of the intake air sucked from the intake port 135.
Alternatively, by shielding the shutter 113 when the fan 105 is not operating, it is possible to prevent moisture in the bathroom BR from flowing into another room through the air inlet 135.

  In addition, about the structure of the filter 120 of the common module 10 demonstrated using FIG. 3 and FIG. 4, the bathroom ventilation drying apparatus 1 of 1 room ventilation and the bathroom ventilation drying apparatus 1 of multiple room ventilation are respectively mentioned so that it may mention later. According to the form of the bathroom ventilation drying apparatus 1, it can change suitably.

Here, a specific structure of the filter 120 will be described with reference to FIG.
FIG. 5 is a plan view illustrating the filter 120 included in the bathroom ventilation drying apparatus 1 according to the embodiment.
More specifically, FIG. 5A shows the filter 120a included in the bathroom ventilation drying apparatus 1a according to the first embodiment, and FIG. 5B shows the filter included in the bathroom ventilation drying apparatus 1b according to the second embodiment. 120b is represented.

As illustrated in FIGS. 5A and 5B, the filter 120 includes an outer frame 121, a knob 122, and a ventilation resistance portion 123.
The outer frame 121 is provided on the outer periphery of the filter 120. The filter 120 is attached to the air inlet 131 by sliding and fixing the outer frame 121 to the rail 107.
The knob 122 is provided at one end of the filter 120. The knob 122 is a portion that is pinched by the user when the filter 120 is inserted into or removed from the rail 107.

The ventilation resistance portion 123 includes a frame portion 124 and a mesh 125.
The frame portion 124 extends in a predetermined direction, and the mesh 125 is provided in a region surrounded by the frame portion 124 and the outer frame 121.

  Next, the structure of each of the filter 120a and the filter 120b will be described.

The shape of the outer frame 121 of the filter 120a is the same as the shape of the outer frame 121 of the filter 120b, for example. The shape of the outer edge of the filter 120a is the same as, for example, the shape of the outer edge of the filter 120b.
On the other hand, the ventilation resistance part 123a of the filter 120a and the ventilation resistance part 123b of the filter 120b are different in structure.

Specifically, as shown in FIGS. 5A and 5B, the width of the frame portion 124b is wider than the width of the frame portion 124a. For this reason, when the filter 120 provided in the air inlet 131 is viewed from below, the area of the frame part 124b is larger than the area of the frame part 124a, and the area of the mesh 125b is smaller than the area of the mesh 125a. When the filter 120 provided at the intake port 131 is viewed from below, the opening area of the intake port 131 provided with the filter 120b is smaller than the opening area of the intake port 131 provided with the filter 120a.
Here, the opening area means an area of a region where the inlet 131 and the mesh of each filter overlap when the filter 120 provided in the inlet 131 is viewed from below. That is, the larger the opening area, the smaller the resistance of the filter 120 against the air flowing through the air inlet 131.
Hereinafter, the resistance of the filter with respect to the air flowing through the intake port 131 is referred to as ventilation resistance.

  In other words, the filter 120 provided at the air inlet 131 is provided with the ventilation resistance portion 123 so that the ventilation resistance of the filter 120 in the second form is higher than the ventilation resistance of the filter 120 in the first form. . The second form is provided with a filter 120b having a relatively high ventilation resistance, and the first form is provided with a filter 120a having a relatively low ventilation resistance.

  The outer frame 121 and the frame portion 124 of the filter 120 are formed, for example, by pouring resin into a predetermined mold and solidifying the resin. At that time, for example, by exchanging a part of the mold corresponding to the frame portion 124, the filter 120a and the filter 120b having different widths of the frame portion 124 and different ventilation resistance portions can be manufactured. In addition, although the example which changes the width | variety of the frame part 124 was demonstrated as an example of the filter 120, you may change the density and thickness of the mesh provided in the filter 120, and may change ventilation resistance.

Next, a state when the filter 120 is provided in the intake port 131 will be described with reference to FIG.
FIG. 6 is a bottom view illustrating a structure in the vicinity of the air inlet 131 included in the bathroom ventilation drying apparatus 1 according to the embodiment.
In FIG. 6, the fan 105 and the scroll 109 are transmitted and the intake port 131 is represented by a broken line.
Further, hereinafter, one direction in which the filter 120 is slid on the rail 107 is referred to as “front”, and the direction opposite to “front” is referred to as “rear”.

The filter 120 is inserted into the rail 107 by sliding in a direction perpendicular to the direction (upward) in which the air sucked from the bathroom BR flows through the air inlet 131.
For example, as illustrated in FIG. 6A, the filter 120 a is slid from the rear (third direction) to the front (fourth direction) and inserted into the rail 107 while the knob 122 is pinched.
Alternatively, as illustrated in FIG. 6B, the filter 120 a may be slid from the front toward the rear and inserted into the rail 107 while the knob 122 is pinched.

That is, the rail 107 is configured to be able to be inserted by sliding the filter 120a from a plurality of different directions that are perpendicular to the vertical direction.
By doing so, the convenience of the bathroom ventilation drying apparatus 1 can be improved.

Further, when the filter 120a is slid forward and held on the rail 107, the position of the ventilation resistance portion 123a with respect to the intake port 131 when the intake port 131 is viewed from below is determined by sliding the filter 120a to the rear side. When the air inlet 131 is viewed from below in the state of being held by the air outlet 107, it is the same as the position of the ventilation resistance portion 123a with respect to the air inlet 131.
By doing so, even when the filter 120 is slid in different directions and inserted into the rail 107, the difference in the ventilation resistance of the filter 120 in each state can be reduced.

In addition, when the filter 120a is slid forward and held on the rail 107, the shape of the ventilation resistance portion 123a when the filter 120a is viewed from below is held by the rail 107 by sliding the filter 120a rearward. In this state, it is the same as the shape of the ventilation resistance portion 123a when the filter 120a is viewed from below.
More specifically, the two shapes are the same, for example, the ventilation resistance portion regardless of the sliding direction of the filter 120a when viewed from the user with the body facing forward and the viewpoint facing upward. This means that the shape of 123a (the shape of the frame portion 124 and the mesh 125) looks the same.
By doing so, even when the filter 120 is slid in different directions and inserted into the rail 107, the difference in ventilation resistance of the filter 120 in each state can be further reduced.

  In FIG. 6, the filter 120a has been described as an example. However, the above-described structures can be similarly applied to the filter 120b.

Moreover, the filter 120 has the 1st surface S1 and the 2nd surface S2 on the opposite side to 1st surface S1, as represented to FIG. 3 and FIG. The rail 107 and the filter 120 may be configured such that the filter 120 can be inserted into the rail 107 regardless of which of the first surface S1 and the second surface S2 faces upward.
By doing so, the convenience of the bathroom ventilation drying apparatus 1 can be improved.

When the filter 120 is viewed from below with the filter 120 held by the rail 107 with the first surface S1 facing upward, the shape of the ventilation resistance portion 123 is the filter with the second surface S2 facing upward. Desirably, the shape of the ventilation resistance portion 123 is the same as that when the filter 120 is viewed from below with the 120 held by the rail 107.
By doing so, it is possible to reduce a difference in ventilation resistance in the filter 120 between the case where the first surface S1 faces upward and the case where the second surface S2 faces upward.

The operation and effect of this embodiment will be described.
In this embodiment, the common module 10 is used for a single room ventilation type (first form) and a multiple room ventilation type (second form). The casing 101 also has a common structure in the first and second embodiments except for the vicinity of the intake port 135. Parts for manufacturing the bathroom ventilation drying apparatus according to the first form and the bathroom ventilation drying apparatus according to the second form by sharing a part of the common module 10 and the casing 101 in the first form and the second form. The number can be reduced and the manufacturing cost can be reduced.
Further, in the present embodiment, in order to increase the flow rate of air from a room other than the bathroom BR in the second form, the ventilation resistance in the first form and the ventilation resistance in the second form are made different in the filter 120. For this purpose, a ventilation resistance portion 123 is provided.
By providing the ventilation resistance part 123 in the filter 120 and making the ventilation resistance of the filter 120 in the first form higher than the ventilation resistance of the filter 120 in the second form, the flow rate of air from the bathroom BR is suppressed, and the bathroom BR The flow rate of air from other rooms can be increased.
That is, according to the present embodiment, it is possible to share parts between the first form and the second form, and it is possible to increase the flow rate of air from a room other than the bathroom BR in the second form. It becomes.
Further, according to the present embodiment, by providing the ventilation resistance portion 123 in the filter 120, the ventilation resistance of the filter 120 in the first form and the ventilation resistance of the filter 120 in the second form can be made different. Ventilation resistance in each form can be easily varied.

When the filter 120 is provided at the air inlet 131, the airflow resistance portion 123 is provided in the filter 120 so that the opening area of the air inlet 131 in the second form is smaller than the opening area of the air inlet 131 in the first form. Provided.
By carrying out like this, the ventilation resistance of the filter 120 in a 2nd form can be made higher than the ventilation resistance of the filter 120 in a 1st form.

  Alternatively, the shape of the frame portion 124 is changed by making the density of the mesh 125b of the ventilation resistance portion 123b of the filter 120b in the second configuration higher than the density of the mesh 125a of the ventilation resistance portion 123a of the filter 120a in the first configuration. It is also possible to make the ventilation resistance of the filter 120 in the second configuration higher than the ventilation resistance of the filter 120 in the first configuration.

  Alternatively, the shape of the frame portion 124 is changed by making the thickness of the mesh 125b of the ventilation resistance portion 123b of the filter 120b in the second configuration thicker than the thickness of the mesh 125a of the ventilation resistance portion 123a of the filter 120a in the first configuration. Without limitation, the ventilation resistance of the filter 120 in the second embodiment may be higher than the ventilation resistance of the filter 120 in the first embodiment.

  Or it is also possible to apply the above-described structure in combination with each other for the filter 120a in the first embodiment and the filter 120b in the second embodiment. That is, in addition to the shape of the frame portion 124 and the mesh 125, the thickness and density of the mesh 125 may be different between the filter 120a and the filter 120b.

Further, in the bathroom ventilation drying apparatus 1 according to the present embodiment, the rail 107 provided at the air inlet 131 includes the filter 120a provided with the ventilation resistance part 123a and the filter 120b provided with the ventilation resistance part 123b. It is configured to be able to hold both.
For this reason, it becomes possible to selectively attach either of the filters 120a and 120b by using the common rail 107 in the first form and the second form.
For example, by making the shape of the outer edge of the filter 120a provided with the ventilation resistance portion 123a the same as the shape of the outer edge of the filter 120b provided with the ventilation resistance portion 123b, the shape is common to the first form and the second form. The rail 107 can be used.

  In the embodiment described above, the case where the ventilation resistance of the filter 120 in the second embodiment is higher than the ventilation resistance of the filter 120 in the first embodiment has been described. However, the ventilation resistance of the filter 120 in the first embodiment is It may be higher than the ventilation resistance of the filter 120 in the second embodiment. That is, the ventilation resistance part 123 may be provided in the filter 120 so that the ventilation resistance of the filter 120 in the first form is higher than the ventilation resistance of the filter 120 in the second form.
