In the following Patent Document 1, it is configured to close the ventilation port when supplying the air from the blower to the circulation outlet, while it is configured to close the circulation outlet when supplying the ventilation to the ventilation port, In order to prevent the air blown from the blower from losing its place in the widening path where the circulation outlet is located and stagnation, the air is swirled in the widening path and is directed to the ventilation opening. (See FIG. 4 of Patent Document 1 below).
JP 2007-205641 A

  In the above-described conventional technology, when ventilating, the air blown from the blower is configured to turn inside the widening path and guide it to the ventilation port. Crossing and colliding with each other, the air is disturbed in this portion, resulting in a problem that ventilation efficiency is reduced and noise is generated.

  The present invention eliminates air turbulence that occurs during ventilation as much as possible even when it is necessary to widen part of the ventilation path when using a wide heater, etc. It aims at providing the bathroom dryer which does not produce generation | occurrence | production of this.

  In order to solve the above problems, the bathroom dryer according to the present invention sucks the air in the bathroom, and circulates the air in the bathroom through the heater, and discharges the air sucked from the bathroom outside the bathroom. In a bathroom dryer provided with a ventilation mode, a main body fixed to the ceiling of the bathroom, and stored in the main body, and provided with a blowout outlet biased to an area on one side in a plan view along the ceiling of the bathroom A ventilation opening for discharging the air sucked from the bathroom to the outside, opened in a region on one side in a plan view along the ceiling of the bathroom, so as to face the blower outlet of the blower, In a plan view along the ceiling of the bathroom, provided in a region on one side, a ventilation passage formed so as to connect the air outlet and the ventilation port, and in a region on the other side in a plan view along the ceiling of the bathroom The air passage provided Widening passage to widen the blowing passage to the other side, across one region in the plan view along the ceiling of the bathroom and the other region, opened from the blowing passage to the widening passage, A circulation outlet for ejecting air sucked from the bathroom into the bathroom, a heater disposed in the circulation outlet, and a horizontal axis provided on the ventilation opening side so as to be openable and closable. An opening / closing damper configured to cover the air outlet in a freely openable / closable manner, and the first passage for guiding the air from the blower to the ventilation port side in the widened passage at a position upstream of the circulation air outlet. A board is provided.

  In the present invention, it extends over a blower passage that connects between the blower outlet and the ventilation opening of the blower formed in a state biased to one side in plan view, and a widening passage for widening the blower passage to the other side. A circulation outlet is provided. Since the heater is provided at the circulation outlet, a wide heater can be used from one side to the other side in plan view. The blower outlet is biased to one side in plan view, and the ventilation opening is also formed in the region on one side, so if you configure it to send air to the heater arranged from one side to the other side, it will open and close When the damper is closed and ventilated, the air flow stagnates in the widening passage. Therefore, in the present invention, a first guide plate for guiding the air supplied from the blower into the widening passage toward the ventilation port side is provided at a position upstream of the circulation blowout port of the widening passage, thereby closing the circulation air outlet and ventilating. In this case, the air flow can be smoothly guided to the ventilation port without stagnating in the widening passage. Therefore, since it is possible to avoid a state in which air collides with each other even during ventilation, a reduction in ventilation efficiency and generation of noise can be reliably reduced.

  In the bathroom dryer according to claim 2, a second guide plate for guiding air to the first guide plate is provided at the outlet of the blower. In the present invention, by providing a second guide plate that guides air to the first guide plate that is largely biased to one side from the blower outlet and disposed in the widening passage, air from the blower can be smoothly and smoothly fed. Since it can be guided to the first guide plate, the efficiency at the time of circulation can be further increased, and the air supplied to the widening passage can be smoothly guided to the ventilation opening even during ventilation, so that the air is stagnated in the widening passage. It is possible to reduce the reduction in ventilation efficiency and noise generation at a high level.

  Moreover, in the bathroom dryer which concerns on this invention 3, the 2nd guide plate which guides air to the said 1st guide plate is provided in the said blower outlet of the said air blower, The said 1st guide plate, the said 2nd guide plate, It is characterized by being arranged separately. The second guide plate directs air to smoothly guide the first guide plate, and the first guide plate directs the directed air to the ventilation port. By disposing the first guide plate and the second guide plate apart from each other, when the air is supplied to the greatly deviated widening passage, if the second guide plate and the first guide plate are made continuous, the widening passage In addition to narrowing the curved passage toward the air, the flow velocity is greatly reduced by the restricted air passage, resulting in an increase in pressure loss. As a result, air can be efficiently transferred from the widened wide passage to the ventilation port side. I found the problem that it would be difficult to guide. In the present invention, this problem is eliminated by a configuration in which the first guide plate and the second guide plate are spaced apart.

  In the bathroom dryer according to claim 4 of the present application, a third guide plate is provided on the back surface of the open / close damper opposite to the surface facing the bathroom side, and the third guide plate is guided from the first guide plate. It is formed so as to guide the air to be directed toward the ventilation port side. The first guide plate is formed upstream of the circulation outlet and guides the air from the blower to the ventilation port side. Therefore, by providing a third guide plate on the back side of the open / close damper that covers the circulation outlet, that is opposite to the surface facing the bathroom, when the open / close damper is closed, the third guide plate is located downstream of the first guide plate. Can be arranged. In addition, the third guide plate is designed to guide the air guided from the first guide plate to the ventilation port side, so even when the open / close damper is closed to ventilate, the air flow is not stagnated. Can lead to the vent. In addition, the presence of the third guide plate eliminates the need for the first guide plate to be largely directed toward the ventilation port, so that the air flow can be made smoother and less lossy, resulting in lower ventilation efficiency and noise generation. Can be reduced at a high level.

  In the bathroom dryer according to claim 5 of the present application, a third guide plate is provided on the back surface of the open / close damper opposite to the surface facing the bathroom, and the third guide plate is guided from the first guide plate. It is formed so as to guide the air to be directed toward the ventilation port side, and a fourth guide plate is provided on a surface of the open / close damper facing the bathroom side, and the fourth guide plate is the third guide plate It is formed so that it may extend toward the non-ventilation opening | mouth side used as the direction which cross | intersects the direction which extends. The third guide plate is designed to guide the air guided from the first guide plate to the ventilation port side, so even when the open / close damper is closed to ventilate, the air flow is not stagnated to the ventilation port. Can lead to. On the other hand, a fourth guide plate is provided on the surface of the open / close damper opposite to the surface on which the third guide plate is formed, and the fourth guide plate is in a direction crossing the direction in which the third guide plate extends. Thus, it is formed to extend toward the non-ventilation port side. Therefore, when the open / close damper is closed, the fourth guide plate functions to guide the air directed toward the ventilation port by the first guide plate in the opposite direction to the non-ventilation port and to direct it toward the circulation outlet. Will do. As a result, when the open / close damper is opened, air can be supplied to the circulation outlet uniformly without being affected by the first guide plate, and the heater arranged at the circulation outlet is similarly universal. Since air can be supplied without any problem, it is possible to reliably avoid a decrease in heating efficiency due to the provision of the first guide plate, which is extremely effective in practice.

  In the bathroom dryer according to claim 6 of the present application, a third guide plate is provided on the back surface of the open / close damper opposite to the surface facing the bathroom, and the third guide plate is guided from the first guide plate. It is formed so as to guide the air to be directed toward the ventilation port side, and a side wall toward the ventilation port of the widening passage is formed to spread outward toward the ventilation port side, The third guide plate is formed along the side wall. Since the side wall from the wide passage toward the ventilation port is formed to be inclined toward the ventilation port side, the side wall formed in the direction intersecting the direction of the air flowing from the upstream side is It forms so that it may incline in the direction in alignment with the direction of the flow of air. Therefore, the air flowing from the upstream side can be smoothly directed to the ventilation port side. Further, since the third guide plate is formed along the side wall, even when the open / close damper is closed and ventilated, the air flow can be smoothly led to the ventilation port without stagnating.

  Further, in the bathroom dryer according to claim 7 of the present application, a protruding bulge is provided on the back surface of the opening / closing damper opposite to the surface facing the bathroom, and the bulge is configured to supply air to the ventilation It is an area on the other side in a plan view along the ceiling of the bathroom so as to be guided to the mouth, and is provided on the ventilation port side. Since the bulging portion is provided on the back surface of the open / close damper opposite to the surface facing the bathroom, it can be arranged to guide the air to the ventilation opening when the open / close damper is closed. In addition, the bulging part is provided on the other side and on the ventilation port side, and is formed as a protruding protruding part instead of a plate-like part. It is difficult to turn around, and even when the open / close damper is closed to ventilate, it can be led to the ventilation opening without stagnating air flow.

  According to the present invention, even if the passage has a widened passage structure in which a part of the passage is widened, air stagnation or turbulence in the widened passage during ventilation is prevented, and ventilation efficiency is improved. It is possible to provide a bathroom dryer that can surely eliminate the occurrence of lowering and noise.
