Description

This disclosure relates to a blower device.

Conventionally, air blowing devices have been installed on the ceiling of a bathroom to ventilate and heat the bathroom. For example, Patent Document 1 describes a bathroom ventilator/heater that includes a main body that houses an exhaust port, air blowing means, and heat generating means, and a louver that covers an opening in the main body formed at the bottom of the main body and is exposed to the bathroom side. Patent Document 2 describes a bathroom dryer that includes a main body that houses a fan, etc., a grill that is provided on the underside of the case, and an intake port that opens along the outer edge of the grill in all four directions.

When using the bathroom, moisture and water droplets from the bathroom that are sucked into the device may adhere to the case of the blower. Moisture and water droplets captured by a filter installed at the air intake of the blower may drip onto the back of the front panel, causing water to accumulate. In addition, if there is a large difference between the temperature in the bathroom and the outside air temperature above the ceiling, for example, condensation may form inside the case of the blower.

Patent No. 4202105 Patent No. 4432654

However, conventional bathroom drying devices and the like have the following problems. The louvers described in Patent Document 1 are configured in a flat shape, so condensation water accumulates evenly on the back surface of the front panel. Generally, on the back surface of the front panel, the suction wind speed is strong in the area close to the suction port and weaker in the area farther from the suction port. As a result, condensation water that accumulates in the area on the back surface of the louvers where the suction wind speed is slow is difficult to dry and takes a long time to dry, which may lead to the growth of mold.

In addition, the front panel described in Patent Document 2 is formed in a curved shape with the center side in the width direction expanding downward, and the center part in the width direction of the panel is the lowest position (lowest point), and condensation water accumulates in the low part of the panel. However, in the front panel of Cited Document 2, the lowest point of the panel is in a position that is shifted from directly below (below) the air intake port, and in this position, it takes time for condensation water that has formed at the edge of the back surface of the curved panel to reach the center of the panel. As a result, it takes a long time for the condensation water to dry, which may cause mold to grow.

Therefore, the present disclosure aims to solve the above problem by providing a blower device that can dry condensation water that accumulates on the front panel without taking a long time.

The air blower according to the present disclosure comprises a main body attached to a ceiling of a room, a panel attached to the main body so as to cover the room side of the main body, and a first air inlet formed between the main body and the panel in a side view, the main body having a second air inlet for drawing in air from the room via the first air inlet and a first air outlet for blowing air from the main body into the room, the panel covering the second air inlet and having a first portion protruding into the room and configured to incline towards the main body from a lowermost portion protruding furthest into the room in a side view, and a second portion continuous with the first portion and positioned closer to the main body than the first portion. and a second section having an opening connecting the first air outlet and the chamber, the first air inlet is formed between the first section and the main body, and in a front view, a third air inlet is formed between the main body and the first section, and the lowest section includes a collection section for guiding and storing condensation water adhering to at least one of the surface of the panel facing the main body and the inside of the main body, the collection section being positioned directly below the second air inlet of the main body on the first section side of the panel and formed in a position along the intake air duct through which the air sucked in from the first air inlet passes, and the height from the main body to the lowest section is configured to be greater than the height of the third air inlet .

According to the present disclosure, the bottom part of the panel (first part) protruding toward the bathroom side is positioned directly below the first air inlet of the main body. In other words, the bottom part is positioned directly below the first air inlet where the air intake speed is fast, so that condensation water can be guided to the bottom part and the condensation water guided to the bottom part can be dried in a short time. As a result, the growth of mold can also be suppressed.

A preferred embodiment of the present disclosure will be described in detail below with reference to the attached drawings.

[First embodiment]
Figure 1 is a perspective view of bathroom ventilator/dryer/heater 1A according to the first embodiment, and Figure 2 is an exploded perspective view of bathroom ventilator/dryer/heater 1A. Figure 3A is a cross-sectional view of bathroom ventilator/dryer/heater 1A according to the first embodiment, and Figure 3B is a cross-sectional view of main part X of bathroom ventilator/dryer/heater 1A shown in Figure 3A.

In this embodiment, the side of the exhaust duct joint 34 at one end of the bathroom ventilator, which is rectangular in plan view when viewed from inside the bathroom, is defined as the right side, and the opposite side is defined as the left side. The front panel (panel) 4A side (vertical direction) of the bathroom ventilator, dryer, and heater 1A is defined as the bottom side, and the opposite side is defined as the top side. The near side in the short direction of the bathroom ventilator, dryer, and heater 1A is defined as the front side, and the opposite side is defined as the rear side. In this embodiment, a side view refers to viewing the bathroom ventilator, dryer, and heater 1A from the short direction of the bathroom ventilator, dryer, and heater 1A. A front view refers to viewing the bathroom ventilator, dryer, and heater 1A from the long direction of the bathroom ventilator, dryer, and heater 1A. Directly below the main body suction port 20 refers to being located in the opening area when the main body suction port 20 is lowered vertically.

As shown in Figures 1 to 3A, the bathroom ventilator/dryer/heater 1A comprises a device main body (main body) 3 that is attached to the ceiling of the bathroom, a front panel 4A that is attached to the underside of the device main body 3 so as to cover the bathroom side, a front suction port (first suction port) 41 and a rear suction port (first suction port) 42 that are formed between the device main body 3 and the front panel 4A, and a main body suction port (second suction port) 20.

The device body 3 has a body suction port 20 through which air in the bathroom is sucked in through the front suction port (first suction port) 41 and the rear suction port (first suction port) by the drive of the circulating ventilation fan 2 provided in the device body 3 passes, a body outlet (first outlet) 21 arranged in line with the body suction port 20 in the longitudinal direction of the device body 3 and through which air heated by the heater 5 provided in the device body 3 passes, and a ventilation outlet 23 that exhausts the air sucked in from the body suction port 20 to the outside. As shown in FIG. 2, the body suction port 20 is an opening defined by the left wall 30b, front wall 30c, rear wall 30d of the body case 30, and the left wall 50a of the air passage forming frame body 50, and is formed on the underside of the device body 3. The upper side of the main body suction port 20 is connected to the fan suction port 24, and the lower side is connected to the front suction port (first suction port) 41 and the rear suction port (first suction port). The main body suction port 20 has a larger opening area than the fan suction port 24, is rectangular in plan view, and is located above the collection section 46 provided on the front panel 4A. The main body air outlet 21 is formed by an air passage forming frame 50.

The device main body 3 also includes a main body case 30 that houses the circulating ventilation fan 2 and heater 5, etc., and a metal case 31 that covers the outer periphery of the main body case 30. The main body case 30 is formed, for example, from a resin material and is configured as a box with an open bottom. A flange portion 32 that protrudes outward is integrally formed on the lower peripheral edge of the main body case 30. An exhaust duct joint 34 that communicates with the ventilation outlet 23 is attached to the right wall 30a of the metal case 31.

As shown in Figures 2 and 3A, the circulation ventilation fan 2 includes an impeller 25 and a fan motor 26 that drives the impeller 25.

The impeller 25 has many blades arranged at equal intervals in the circumferential direction. The impeller 25 rotates based on the drive of the fan motor 26, and blows the air drawn in from the main body suction port 20 out from the center to the outside in a centrifugal air path.

The fan motor 26 is disposed inside the impeller 25 and is attached to the top surface of the main body case 30 with the rotating shaft 26a facing downward. The rotating shaft 26a of the fan motor 26 is inserted into a shaft hole provided in the impeller 25. The impeller 25 is fixed to the rotating shaft 26a, and the impeller 25 rotates when the fan motor 26 is driven.

A fan air passage is formed in the main body case 30, which runs along the outer periphery of the impeller 25 housed in the main body case 30 and extends tangentially from the outer periphery toward the air passage switching damper 6. As a result, air sucked in from the main body suction port 20 by the drive of the impeller 25 is blown out toward the air passage switching damper 6 via the fan air passage.

A lower cover 33 that covers the opening of the device main body 3 is attached to the underside of the main body case 30. Directly below the impeller 25 of the lower cover 33 (at a position opposite the impeller 25), a fan intake port 24 that is circular in plan view and called a bell mouth is formed. The fan intake port 24 passes air drawn in through the front intake port 41, rear intake port 42, and main body intake port 20 of the front panel 4A and directs it to the impeller 25.

The heater 5 is provided at the main body outlet 21 through which the air blown out from the impeller 25 passes, and generates heat when energized (driven) to heat the air passing through the main body outlet 21. When not energized, the heater 5 allows air that corresponds to the temperature in the bathroom to pass through without heating the air passing through the main body outlet 21. The heater 5 is, for example, a PTC heater, and has a rod-shaped heater member extending in the short direction of the main body case 30, and a number of fins provided along the longitudinal direction of the heater member. In this embodiment, two heater members are arranged side by side in the short direction of the main body outlet 21, and the longitudinal direction of the heater members is arranged along the longitudinal direction of the main body outlet 21.

The bathroom ventilator/dryer/heater 1A is equipped with an air path switching damper 6 that switches the air path of the air blown out from the fan air path by driving the impeller 25 to either the main body air outlet 21 side, the ventilation air outlet 23 side, or both the main body air outlet 21 side and the ventilation air outlet 23 side. The air path switching damper 6 is composed of a plate-shaped member that is approximately arc-shaped in side view, and its base end is rotatably supported on an unsupported shaft provided below the ventilation air outlet 23 inside the fan case. The air path switching damper 6 rotates about the shaft as a fulcrum by driving a damper motor (not shown), opening and closing one or both of the main body air outlet 21 and the ventilation air outlet 23.

When the air path switching damper 6 moves to a circulation position that closes the ventilation outlet 23, as shown by the solid line in Figure 3A, the main body outlet 21 opens, and a circulation air path is formed that connects the fan intake 24 to the main body outlet 21 via the fan air path.

When the air passage switching damper 6 is moved to a ventilation position in which the main body air outlet 21 is closed, as shown by the dashed line in FIG. 3A, the ventilation air outlet 23 opens, and a ventilation air passage is formed that connects the fan intake 24 to the ventilation air outlet 23 via the fan air passage.

In addition, when the air path switching damper 6 moves to the circulation ventilation position (intermediate position) between the circulation position and the ventilation position, as shown by the dashed line in Figure 3A, both the main body air outlet 21 and the ventilation air outlet 23 open, and a circulation air path that connects from the fan inlet 24 to the main body air outlet 21 is formed, and a ventilation air path that connects from the fan inlet 24 to the ventilation air outlet 23 is formed.

The bathroom ventilating, drying and heating appliance 1A is equipped with an intermediate panel 7A. As shown in Figures 2 and 3A, the intermediate panel 7A is disposed between the device body 3 and the front panel 4A, and is removably attached to the underside of the device body 3. The intermediate panel 7A has a rectangular shape in a plan view, and is formed to be approximately the same size and shape as the device body 3 in a plan view.

A filter 70 for removing specific components such as dust contained in the air sucked from the bathroom is attached between the main body suction port 20 and the collecting section 46 at a position below the main body suction port 20 side of the intermediate panel 7A. The filter 70 is formed with an outer shape slightly smaller than the main body suction port 20 and is detachably attached to the intermediate panel 7A. In this embodiment, the filter 70 is formed, for example, in a rectangular shape in a plan view, and the filter 70 can be removed or attached from the front side of the intermediate panel 7A where the front suction port 41 is located, which is formed so that the opening dimension is large, or the rear side of the intermediate panel 7A where the rear suction port 42 is located. The filter 70 is provided at a position protruding toward the front panel 4A side from the main body air outlet 21. The filter 70 is also located at a position close to the left wall 30b of the main body case 30 directly below the main body suction port 20, and is arranged so as to overlap a part of the main body suction port 20 in a plan view (viewed from above). The filter 70 may also be placed directly below the fan intake 24.

As shown in FIG. 2, an air outlet grill 72 is provided directly below (opposite) the main body air outlet 21 of the intermediate panel 7A to blow air from the main body air outlet 21 into the bathroom in a specified direction. The air outlet grill 72 is formed with approximately the same shape and size as the main body air outlet 21.

In addition, the intermediate panel 7A is structured so that the area where the filter 70 is attached (the area on the main body air inlet 20 side) protrudes toward the bathroom side beyond the area where the air outlet grill 72 is provided (the area on the main body air outlet 21 side) via a step portion 75. In this embodiment, the thickness of the area where the filter 70 is attached is configured to be thicker than the thickness of the area where the air outlet grill 72 is provided.

As shown in Figs. 1 and 3A, the front panel 4A has a first section 40a that covers the main body suction port 20 and protrudes into the bathroom, a second section 40b that is continuous with the first section 40a and is located closer to the device main body 3 than the first section 40a and has a panel outlet 47 that connects the first main body outlet 21 to the bathroom, and a collection section (lowermost section) 46 for guiding and collecting condensation water that has adhered to the back surface 40c of the front panel 4A and inside the main body case 30, etc. The first section 40a is located below the main body suction port 20 and the filter 70, the second section 40b is located below the main body outlet 21, and the collection section 46 is provided on the first section 40a side.

The front panel 4A is, for example, rectangular in plan view and is formed to be approximately the same as or slightly larger than the external shape of the device body 3 in plan view. In this embodiment, the front panel 4A is positioned so that its longitudinal direction is aligned with the left-right direction of the bathroom ventilator/dryer/heater 1A and its transverse direction is aligned with the front-rear direction of the bathroom ventilator/dryer/heater 1A.

When viewed from the side along the bathroom ceiling, the first portion 40a of the front panel 4A has a curved shape that curves gradually from the apex at the collecting portion 46, which is located at the most protruding position on the back surface of the front panel 4A toward the bathroom, toward the left and right, so as to approach the device main body 3. When viewed from the side along the bathroom ceiling, the second portion 40b of the front panel 4A has a curved shape that curves so that the position facing the main body air outlet 21 approaches the device main body 3, and curves slightly away from the device main body 3 toward the left and right. In this way, in this embodiment, the first portion 40a and the second portion 40b form a continuous wave-shaped curved surface.

A front suction port (first suction port) 41 and a rear suction port (first suction port) 42 are formed between the first portion 40a of the front panel 4A and the device body 3. The front suction port 41 is formed on the front surface (side surface) at one end of the short side of the front panel 4A, and draws in air in the bathroom from between the curved surface on the first portion 40a side and the flange portion 32. The rear suction port 42 is formed on the rear surface (side surface) at the other end of the short side of the front panel 4A and in a position opposite the front suction port 41, and draws in air in the bathroom from behind the front panel 4A. .

A left side suction port 43 (third suction port) is formed between the first portion 40a of the front panel 4A and the device body 3. The left side suction port 43 is formed on the left side at one end of the front panel 4A in the longitudinal direction, and draws in air in the bathroom from between the front panel 4A and the flange portion 32. A right side suction port 44 is formed between the second portion 40b of the front panel 4A and the device body 3. The right side suction port 44 is formed on the right side at the other end of the front panel 4A in the longitudinal direction and in a position opposite the left side suction port 43, and draws in air in the bathroom from the right side of the front panel 4A.

As shown in Fig. 1, this configuration forms a first intake air passage P1 along the short side of the front panel 4A through which air sucked in from the front suction port 41 passes on the back surface 40c of the front panel 4A on the first portion 40a side, and a second intake air passage P2 along the short side of the front panel 4A through which air sucked in from the rear suction port 42 passes. In addition, a third intake air passage P3 along the long side of the front panel 4A through which air sucked in from the left side suction port 43 passes is formed on the back surface 40c of the front panel 4A on the first portion 40a side.

In this embodiment, the front panel 4A is formed in a wave shape when viewed from the short side along the ceiling of the bathroom, and the second section 40b side is curved so that it approaches the device main body 3. Since the main body air outlet 21 is located on the second section 40b side, it is essentially closed, and the amount of air sucked in is significantly less than the front air inlet 41 on the first section 40a side. Similarly, the right side air inlet 44 is configured to have a lower opening height than the left side air inlet 43, and the amount of air sucked in is less than the left side air inlet 43.

The outlet grill 72 of the intermediate panel 7A is fitted into the position facing the main body outlet 21 on the second portion 40b side of the front panel 4A, and a panel outlet 47 is formed that connects the main body outlet 21 to the bathroom. The panel outlet 47 is rectangular in plan view, and is formed so that its longitudinal direction is aligned with the lateral direction of the front panel 4A.

As shown in Figs. 3A and 3B, the collecting section 46 guides and collects condensation water adhering to the back surface 40c of the front panel 4A and the inside of the main body case 30. The collecting section 46 is formed on the first portion 40a side of the front panel 4A, directly below (opposing) the main body suction port 20 of the device main body 3, and along the first intake air duct P1 and the second intake air duct P2 through which the air sucked in from the front intake port 41 and the rear intake port 42 passes (see Fig. 1). The collecting section 46 is also provided at the lowest part of the back surface 40c of the front panel 4A, that is, at the position that protrudes most from the bottom surface of the device main body 3 toward the bathroom side. Thus, in this embodiment, the collecting section 46 is provided at a position where the suction wind speed is high and the distance to the end (e.g., the left end) of the back surface 40c of the front panel 4A is short. Preferably, the collection section 46 is provided directly below the approximate center of the filter 70, shortening the distance from the condensation water that has formed on the edge of the back surface of the first section 40a of the front panel 4A to the collection section 46, allowing the condensation water guided to the bottom to dry in a short time.

Next, we will explain the relationship between the heights of the intake air ducts at the front intake port 41, rear intake port 42, left side intake port 43, and right side intake port 44.

3B, the intake air passage height A of the first intake air passage P1 and the second intake air passage P2 in which the collecting section 46 on the first portion 40a side of the front intake port 41 and the rear intake port 42 is provided, and the intake air passage height B of the third intake air passage P3 in the left side intake port 43 satisfy the relationship of intake air passage height A > intake air passage height B. Here, the intake air passage height A is the distance between the collecting section 46 provided at the lowest position on the back surface 40c of the front panel 4A and the lower surface of the intermediate panel 7A (flange portion 32). The intake air passage height B is the distance between the left end side of the back surface 40c of the front panel 4A and the lower surface of the intermediate panel 7A (flange portion 32). In this way, by configuring the intake airflow duct height A to be higher than the intake airflow duct height B, the amount of air sucked in through the front intake port 41 and the rear intake port 42 can be significantly increased compared to the amount of air sucked in through the left side intake port 43.

In addition, in this embodiment, the air intake duct on the second portion 40b side is substantially blocked, thereby preventing the air sucked in from the front intake port 41 on the first portion 40a (main body intake port 20) side from dispersing. As a result, the amount of air sucked in through the intake duct passing through the collecting portion 46 can be increased.

As described above, according to the first embodiment, the collecting section 46 is provided at the bottom of the first portion 40a of the back surface 40c of the front panel 4A, so that the condensation water adhering to the inner surface of the main body case 30, the back surface 40c of the front panel 4A, etc. flows along the back surface 40c inclined from the left and right direction and is guided to the collecting section 46. This allows the condensation water to be collected in one place in the collecting section 46, and the distance from the condensation water generated at the end of the back surface 40c to the collecting section 46 can be shortened, so that the condensation water can be dried efficiently. In addition, according to the first embodiment, the collecting section 46 is provided along the intake air duct where the air volume and speed of the air sucked from the bathroom are large, so that a lot of air can be applied to the condensation water collected in the collecting section 46, and the drying of the condensation water can be promoted. This makes it possible to suppress the growth of mold in the bathroom ventilating, drying and heating device 1A including the front panel 4A.

In addition, according to the first embodiment, the intake air passage on the second portion 40b side of the front panel 4A is substantially blocked, so that the air sucked in from the front air inlet 41 on the first portion 40a side of the front panel 4A can be prevented from dispersing to the second portion 40b side. This increases the amount of air sucked into the intake air passage passing through the collecting portion 46 on the front panel 4A, and further promotes drying of condensation water.

[Second embodiment]
The second embodiment of bathroom ventilating, drying and heating appliance 1B differs from the first embodiment of bathroom ventilating, drying and heating appliance 1A in that device body 3 is provided with two air outlets, first main body air outlet 21 and second main body air outlet 29. Note that in the second embodiment of bathroom ventilating, drying and heating appliance 1B, components that are essentially the same as those in the first embodiment of bathroom ventilating, drying and heating appliance 1A are given the same reference numerals and duplicated explanations will be omitted.

Figure 4 is a perspective view of bathroom ventilator/dryer/heater 1B according to the second embodiment, Figure 5 is an exploded perspective view of bathroom ventilator/dryer/heater 1B, and Figure 6 is a cross-sectional view of bathroom ventilator/dryer/heater 1B.

As shown in Figures 4 to 6, the bathroom ventilator/dryer/heater 1B comprises a device body 3 that houses the circulating ventilation fan 2 and heater 5, a front panel 4B attached to the underside of the device body 3 so as to be exposed to the bathroom, and an intermediate panel 7B provided between the device body 3 and the front panel 4B.

The device main body 3 has a main body suction port 20 and a fan suction port 24 through which air in the bathroom sucked in from the front suction port 41 of the front panel 4B by the operation of the circulating ventilation fan 2 passes, a first main body outlet 21 through which air heated by the heater 5 passes when it is blown out into the bathroom, and a second main body outlet 29 through which air not heated by the heater 5 passes when it is blown out into the bathroom.

The second main body outlet 29 is located on the opposite side of the first main body outlet 21 from the main body inlet 20, between the first main body outlet 21 and the right wall 30a of the main body case 30. In this embodiment, the heater 5 is not provided at the second main body outlet 29, and the air blown out from the impeller 25 passes through without being heated.

A removably attached filter 70 is attached to the lower part of the middle panel 7B on the side of the main body intake port 20 to remove specific components such as dust contained in the air sucked in from the bathroom.

Directly below (opposing) the first main body air outlet 21 of the intermediate panel 7B is provided a first air outlet grill 72 for blowing out the air that has passed through the first main body air outlet 21 in a predetermined direction. Directly below (opposing) the second main body air outlet 29 of the intermediate panel 7B and adjacent to the right side of the first air outlet grill 72 is provided a second air outlet grill 73 for blowing out the air that has passed through the second main body air outlet 29 in a predetermined direction.

The front panel 4B is provided with a first panel outlet 47 directly below (opposite) the first outlet grill 72 for blowing air that has passed through the first outlet grill 72, etc., into the bathroom. The front panel 4B is also provided with a second panel outlet 48 directly below the second main body outlet 29 for blowing air that has passed through the second outlet grill 73, etc., into the bathroom. The front panel 4B is also provided with a collection section 46 for guiding and collecting condensation water that has adhered to the back surface 40c and inside the main body case 30, etc.

According to the second embodiment, by providing the second main body outlet 29 in addition to the first main body outlet 21 on the device main body 3, heated air can be blown out from the first main body outlet 21, and unheated air can be blown out from the second main body outlet 29. The air blown out from the second panel outlet 48 of the front panel 4B has a higher relative humidity and is heavier than the air blown out from the first panel outlet 47. Therefore, by blowing air out from the second panel outlet 48 toward one wall surface in the bathroom, it is possible to generate an air flow that stirs the bathroom. That is, it is possible to generate an air flow that flows along one wall surface in the bathroom to the lower layer of the bathroom, flows from that lower layer toward the other wall surface in the bathroom, and further flows upward from the lower layer of the other wall surface along the other wall surface. This makes it possible to generate a wind flow that stirs the air throughout the bathroom.

[Third embodiment]
The third embodiment of bathroom ventilating, drying and heating appliance 1C differs from the second embodiment of bathroom ventilating, drying and heating appliance 1B in that device body 3 is provided with two units, first main body outlet 21 and second main body outlet 29, and a third panel outlet 49 corresponding to second main body outlet 29 is provided on the back surface 40c of front panel 4C. Note that in the third embodiment of bathroom ventilating, drying and heating appliance 1C, components that are essentially the same as those in the first embodiment of bathroom ventilating, drying and heating appliance 1A and the second embodiment of bathroom ventilating, drying and heating appliance 1B are given the same reference numerals and duplicated explanations will be omitted.

Figure 7 is a perspective view of the bathroom ventilator/dryer/heater 1C according to the third embodiment, Figure 8 is an exploded perspective view of the bathroom ventilator/dryer/heater 1C, and Figure 9 is a cross-sectional view of the bathroom ventilator/dryer/heater 1C.
