The dropped water is received by the guide portion 11c outside the inlet grill 11a.

  Here, the filter 110 attached to the front panel 11 has a configuration in which the frame portion 110b is attached to the guide portion 11c, and water may be received by the frame portion 110b of the filter 110 attached to the guide portion 11c. .

<Examples of effects of bathroom heating / ventilating / drying apparatus of this embodiment>
In the bathroom heating / ventilating / drying apparatus 1A, when the circulation fan 2 is driven, the air in the bathroom 100 is sucked into the circulation fan 2 from the suction grille 11a of the front panel 11 attached to the apparatus body 10 and sucked from the bathroom 100. The air thus blown out is blown out from the blowout grill 11 b of the front panel 11 into the bathroom 100 by the circulation fan 2.

  In the bathroom heating / ventilating / drying apparatus 1 </ b> A, the heater 5 is driven in conjunction with the driving of the circulation fan 2, so that warm air is blown into the bathroom 100 and, if the heater 5 is not driven, the temperature of the bathroom 100. The wind according to the above is blown out into the bathroom 100.

  Further, the bathroom heating / ventilating / drying apparatus 1A sets the air path opening / closing damper 6A to the open position P2 indicated by a solid line in FIG. 1, and when the ventilation fan 3 is driven, the air in the bathroom 100 is sucked into the inlet grill 11a of the front panel 11. Is sucked into the ventilation fan 3 through the bathroom suction air passage 14a and exhausted to the outside through the exhaust duct 12 from the ventilation fan 3.

  Further, the bathroom heating / ventilation drying apparatus 1A sets the air passage opening / closing damper 6A to the open position P2 indicated by the solid line in FIG. 1 or the closed position P1 indicated by the broken line, and when the ventilation fan 3 is driven, Air in the toilet 103 is sucked into the ventilation fan 3 from the auxiliary suction grill 13a through the auxiliary suction duct 13 and exhausted to the outside through the exhaust duct 12 from the ventilation fan 3.

  The bathroom heating / ventilating / drying apparatus 1A according to the present embodiment drives the ventilation fan 3 by setting the air passage opening / closing damper 6A to the open position P2 indicated by a solid line in FIG. 1 as an operation mode executed in accordance with a predetermined program set in advance. Thus, a 24-hour ventilation operation mode in which a normal ventilation operation is performed with a predetermined ventilation airflow is provided.

  The bathroom heating / ventilating / drying apparatus 1A performs a heating operation in which warm air is blown into the bathroom 100 by driving the circulation fan 2 and the heater 5 by setting the air path opening / closing damper 6A to the closed position P1 indicated by a broken line in FIG. A heating operation mode and a cool air operation mode in which the circulation fan 2 is driven to perform a cool air operation in which air is blown into the bathroom 100 according to the temperature of the bathroom 100 are provided.

  Furthermore, the bathroom heating ventilation drying apparatus 1A sets the air path opening / closing damper 6A to the open position P2 indicated by a solid line in FIG. 1, and drives the ventilation fan 3 to increase the predetermined ventilation larger than the ventilation air volume in the 24-hour ventilation operation mode. It has a ventilation operation mode in which ventilation operation of the bathroom 100 is mainly performed by the air volume.

  Further, the bathroom heating / ventilating / drying apparatus 1A performs the ventilation operation in the bathroom 100 by driving the circulation fan 2, the heater 5, and the ventilation fan 3 with the air path opening / closing damper 6A in the open position P2 indicated by the solid line in FIG. However, it has a drying operation mode in which hot air is blown into the bathroom to perform the drying operation.

  Since the bathroom heating / ventilating / drying apparatus 1A is installed in the bathroom 100 where the humidity is high, in the ventilation operation mode in which the ventilation fan 3 is driven with the air path opening / closing damper 6A as the open position P2, the humidity in the bathroom 100 is high. Air is sucked from the inlet grill 11a.

  When the humid air in the bathroom 100 is sucked from the inlet grill 11a, the bathroom heating / ventilating / drying apparatus 1A opens and closes the air path provided in the ventilation inlet 15 of the bathroom inlet air passage 14a communicating with the inlet grill 11a. Water droplets may adhere to the damper 6A.

  In the bathroom heating / ventilating / drying apparatus 1A, if water droplets are attached to the air path opening / closing damper 6A at the open position P2, the water may drop along the vertical air path opening / closing damper 6A.

  Therefore, in the bathroom heating / ventilating / drying apparatus 1A, the water receiving portion 11d is provided on the inner surface of the front panel 11 at a position facing the lower end position N of the side portion 61 in the open position P2 of the air passage opening / closing damper 6A.

  Thereby, when water is dripped from the air path opening / closing damper 6A opened to the open position P2, the water receiving portion 11d receives water and can store the water in the front panel 11.

  The bathroom heating / ventilating / drying apparatus 1A is provided with an opening grill 11a provided with an opening on the lower surface of the front panel 11, but in this example, a water receiving portion 11d is provided outside the suction opening grill 11a. Even when water drops from the air passage opening / closing damper 6A opened to the open position P2, it is possible to prevent water from dropping from the suction grill 11a to the bathroom 100.

  In a bathroom heating / ventilating / drying device, if a panel member is attached to the front face of the inlet grille and air is sucked in from the side of the front panel, the water dripped from the inlet grille with the panel member covering the front face of the inlet grille. Can receive.

  However, if the air can be sucked from the side of the front panel, the front panel becomes thick and the appearance in the bathroom deteriorates. In addition, the number of parts constituting the front panel increases, leading to an increase in cost. Furthermore, the weight of the front panel increases.

  Moreover, if it is set as the structure which can inhale air from the side of a front panel, a suction inlet will become narrow and ventilation resistance will become large and desired ventilation airflow will not be obtained. When the rotation speed of the ventilation fan is increased to obtain a desired ventilation air volume, the sound becomes louder. In addition, power consumption increases. If the dimension between the front panel and the panel member is enlarged, the suction port can be enlarged, but the front panel becomes thicker and the appearance in the bathroom is deteriorated.

  Furthermore, since the front surface of the suction grill is covered with a panel member, the state of the filter cannot be visually confirmed unless the filter provided inside the suction grill is removed from the front panel. Thereby, it cannot be easily confirmed that it is used in a state where clogging due to adhesion of dust or the like occurs, and there is a possibility that a desired ventilation air volume cannot be obtained.

  Further, when the air is sucked in from the side of the front panel, the flow of the sucked air becomes a flow along the ceiling panel, and there is a possibility that dirt is attached to the ceiling panel.

  On the other hand, in the bathroom heating / ventilating / drying apparatus 1A of the present embodiment, the water receiving portion 11d is provided with the water receiving portion 11d on the inner surface of the front panel 11, so that the water receiving portion 11d has substantially the same shape as the conventional front panel. The appearance can be improved.

  Further, the water receiving portion 11d can be realized by integrally forming a convex portion or a groove portion on the inner surface of the front panel 11 made of a resin material, and the number of parts constituting the front panel 11 increases. And an increase in cost can be suppressed. Furthermore, an increase in the weight of the front panel 11 can be suppressed.

  Moreover, the state of the filter 110 attached to the front panel 11 can be visually observed from the opening of the inlet grill 11a. As a result, the state of the filter 110 such as the degree of contamination can be confirmed without removing the filter 110 from the front panel 11, and the timing of cleaning and replacement of the filter 110 can be accurately determined to reduce the ventilation airflow. The occurrence of an event can be prevented in advance.

  Furthermore, since the inlet grill 11a is opened downward, the flow of air sucked from the inlet grill 11a is mainly the downward flow, and the ceiling panel is attached with dirt on the ceiling panel. It is possible to suppress the generation of air flow along the line.

  Even if a water receiving member such as a drain pan is provided as a separate member between the air path opening / closing damper and the inlet grille, water dripping from the inlet grille can be received, but the number of parts is still increased and the cost is reduced. Leading to a rise. Further, a part of the air passage is blocked by the water receiving member, and the ventilation resistance is increased, so that a desired ventilation air volume cannot be obtained. When the rotation speed of the ventilation fan is increased to obtain a desired ventilation air volume, the sound becomes louder. In addition, power consumption increases.

  On the other hand, in the bathroom heating / ventilating / drying apparatus 1A according to the present embodiment, the water intake portion 11d is provided on the inner surface of the front panel 11, so that the ventilation inlet 15 and the inlet grill 11a are partly provided. The opening area of the ventilation inlet 15 and the inlet grill 11a can be used effectively without being blocked by a member for receiving water. Thereby, an increase in ventilation resistance is suppressed, and a desired ventilation air volume can be obtained without increasing the air volume of the ventilation fan 3. Therefore, noise reduction can be achieved and power consumption can be suppressed.

  FIG. 7 is an explanatory diagram showing the effect of water induction by the shape of the airway opening / closing damper. In the air path opening / closing damper 6A, a concave portion 61a and a convex portion 61b are formed on the side portion 61 that faces downward at the open position P2.

  As a result, water droplets adhere to the air path opening / closing damper 6A at the open position P2, and when water flows through the air path opening / closing damper 6A that is vertically oriented, the center along the longitudinal direction of the air path opening / closing damper 6A In the vicinity, water is guided to both ends along the concave shape of the concave portion 61a as indicated by an arrow A. And the water induced | guided | derived to the both ends of 6 A of air path opening / closing dampers is dripped from the convex-shaped part 61b.

  In this way, the entire position facing the lower end position N of the side portion 61 at the open position P2 of the air path opening / closing damper 6A is provided by guiding the water dropped from the air path opening / closing damper 6A to a desired position. Instead of the configuration in which the water receiving portion 11d is provided, the water receiving portion 11d can be provided only at a position facing the convex portion 61b.

Further, instead of the configuration to induce water in the form of air path opening and closing dampers 6A, the convex member is had as to direct the flow of water to the front and back surfaces of the air passage opening and closing the damper 6A is provided a groove or the like, the desired Water may be guided to the position.

  Next, a technique for preventing dripping of water with an air passage configuration that realizes quietness will be described. In the 24-hour ventilation operation mode described above, the entire building including the bathroom 100, the washroom 102 and the toilet 103 is ventilated. The ventilation air volume in the 24-hour ventilation operation mode is such that the air of the entire building (not shown) including the bathroom 100, the washroom 102, and the toilet 103 is replaced in a predetermined time by performing continuous or intermittent ventilation. Is set.

  Thus, in the bathroom heating ventilation drying apparatus 1A, since the ventilation fan 3 is driven constantly or for a long time by executing the 24-hour ventilation operation mode, the silence of the ventilation fan 3 is required.

  For this reason, 1 A of bathroom heating ventilation drying apparatuses shield the sound which generate | occur | produces with the ventilation fan motor 31 etc. with the circulation fan 2 by arrange | positioning the ventilation fan 3 on the upper side of the circulation fan 2. FIG. Further, the ventilation fan suction port 32a of the ventilation fan 3 is formed on the upper surface of the ventilation fan case 32, so that the sound from the ventilation fan suction port 32a is hardly leaked and the ventilation fan suction is sucked from the suction grille 11a of the front panel 11. The length up to the opening 32a is configured to attenuate sound leaking from the ventilation fan suction port 32a.

  FIG. 8 is a schematic diagram showing the flow of air sucked into the ventilation fan. As described above, in the bathroom heating / ventilation drying apparatus 1 </ b> A, the bathroom suction air passage 14 a and the other-chamber suction air passage 14 b are formed in a space between the metal case 4 and the upper surface of the ventilation fan case 32.

  In the bathroom heating / ventilating / drying apparatus 1 </ b> A, the air A <b> 1 in the bathroom 100 sucked from the suction grill 11 a of the front panel 11 passes through the bathroom suction air passage 14 a from the ventilation suction inlet 15, mainly in the longitudinal direction of the apparatus main body 10. Is sucked into the ventilation fan suction port 32a of the ventilation fan 3 from one end side.

  On the other hand, the air A2 in the washroom 102 and the toilet 103 sucked from the auxiliary suction grill 13a passes through the other room suction air passage 14b, mainly from the other end side in the longitudinal direction of the apparatus body 10, The air is sucked into the ventilation fan suction port 32a of the ventilation fan 3.

  As a result, the high-humidity air A1 sucked from the bathroom 100 and the cold air A2 sucked from the washroom 102 and the toilet 103 are on the upper surface side of the ventilation fan case 32 and in the vicinity of the ventilation fan suction port 32a. Join at.

  Such a bathroom heating / ventilating / drying apparatus 1A is installed in such a manner that the apparatus main body 10 can be put into an opening (not shown) provided in the ceiling 100a of the bathroom 100, so that the height of the apparatus main body 10 is the ceiling where the apparatus is installed. It must fit within the height dimension of the back.

  For this reason, in the bathroom heating / ventilating / drying apparatus 1A having a configuration in which the ventilation fan 3 is arranged on the upper side of the circulation fan 2, it is necessary to keep the size of the apparatus main body 10 in the height direction low. The dimension in the height direction of the chamber suction air passage 14b is kept low.

  Thereby, in the bathroom heating ventilation drying apparatus 1A, the vicinity of the ventilation fan suction port 32a where the air A1 with high humidity sucked from the bathroom 100 and the cold air A2 sucked from the washroom 102 and the toilet 103 merge, This is a relatively narrow space formed between the metal case 4 and the upper surface of the ventilation fan case 32.

  Condensation occurs when the air with high humidity and cold air merge. However, when the air confluence is formed in a relatively narrow space, the location where condensation occurs is limited to a narrow range. Moreover, since the location where condensation occurs is on the upper surface of the ventilation fan case 32, water due to condensation is prevented from dripping from the bathroom suction air passage 14 toward the ventilation suction port 15.

  Further, since the ventilation fan motor 31 is attached to the ventilation fan suction port 32a, the high-humidity air A1 sucked from the bathroom 100 and the cold air A2 sucked from the bathroom undressing place 102 and the toilet 103 merge. In the vicinity of the ventilation fan suction port 32a, the ventilation fan motor 31 functions as a partition that partitions the air flow.

  Thereby, it is suppressed that the flow of air in which high humidity air and cold air merge is generated on the upper surface side of the ventilation fan case 32, and the occurrence of condensation is suppressed.

  Therefore, in the bathroom heating / ventilation drying apparatus 1A, the ventilation fan suction port 32a of the ventilation fan 3 arranged on the upper side of the circulation fan 2 is formed on the upper surface of the ventilation fan case 32, so that the noise reduction is improved. The effects of suppressing the occurrence of condensation and suppressing the dripping of water due to condensation are obtained.

  And by providing the water receiving portion 11d on the inner surface of the front panel 11, it is possible to suppress dripping of water adhering to the air passage opening / closing damper 6A at the open position P2 from the inlet grill 11a of the front panel 11. It is possible to suppress the dripping of water from the inlet grill 11a of the front panel 11 due to condensation or moisture adhering that can occur in the air path on the ventilation fan 3 side.

  Thereby, the water receiver 22d can be provided on the apparatus main body 10 side without increasing the number of components. In addition, the front panel may be provided with a water receiving part, or a conventional panel without a water receiving part may be used. In this example, the water receiving portion 22d is provided integrally with the circulation fan case 22, but the main body case portion 22e constituting a part of the circulation fan case 22 or other components on the apparatus main body 10 side. The structure in which a water receiving part is provided integrally may be sufficient.

<Another embodiment of the bathroom heating ventilation drying apparatus of the present invention>
FIG. 13: is an internal block diagram which shows an example of the bathroom heating ventilation drying apparatus of other embodiment. The bathroom heating / ventilating / drying apparatus 1E is installed in a bathroom 100 having high humidity as shown in FIG. 2 and sucks air from the bathroom 100 and discharges it to the outside. Air is also drawn from the dressing room 102 and the toilet 103 and discharged outside.

  In the bathroom heating / ventilating / drying apparatus 1E, when the toilet 103 shown in FIG. 2 is ventilated, the air path opening / closing damper 6C is closed as shown by a broken line in FIG. A ventilation operation is performed as the position P1.

  When the ventilation operation is performed with the air path opening / closing damper 6C at the closed position P1, the cold air sucked from the toilet 103 or the like passes through the other room suction air path 14b described with reference to FIG. On the other hand, because the other-room suction air passage 14b and the bathroom suction air passage 14a communicate with each other, the lower surface of the air passage opening / closing damper 6C at the closed position P1 is in contact with high-humidity air in the bathroom 100 to open / close the air passage. The upper surface of the damper 6C comes into contact with cold air.

  For this reason, dew condensation may occur on the lower surface of the air path opening / closing damper 6C due to the difference in temperature and humidity between the front and back surfaces of the air path opening / closing damper 6C at the closed position P1, and water droplets may adhere. Therefore, in the bathroom heating / ventilating / drying apparatus 1E, on the inner surface of the front panel 11, the position N1 of the side 63 at the closed position P1 of the air path opening / closing damper 6C and the air path opening / closing damper 6C indicated by a two-dot chain line in FIG. The water receiving portion 11j is provided at a predetermined position facing the lower end position N2 of the side portion 63 at the open position P2. Then, the water adhering to the air path opening / closing damper 6C due to condensation or the like is dropped onto the water receiving portion 11j by the operation of opening the air path opening / closing damper 6C.

  That is, the air path opening / closing damper 6C rotates in a direction in which the side portion 63 is directed downward by a rotation operation with the shaft 60 as a fulcrum from the closed position P1. The air path opening / closing damper 6C is inclined at a predetermined half-open position P3 indicated by a solid line in FIG. 13 in a direction in which the side 63 facing the water receiving portion 11j is lowered, and is attached to the air path opening / closing damper 6C due to condensation or the like. Water is transferred to the air path opening / closing damper 6C and dripped onto the water receiving portion 11j. The air passage opening / closing damper 6C opens the ventilation suction port 15 in the vertical direction along the substantially vertical direction at the open position P2.

  In the bathroom heating / ventilating / drying apparatus 1E, the air path opening / closing damper 6C is opened from the closed position P1 to the open position P2, and for example, the rotation of the air path opening / closing damper 6C is stopped once at the half-open position P3 or the rotation speed is decreased. Thus, the water adhering to the air path opening / closing damper 6C can be reliably dropped onto the water receiving portion 11j.

  Here, if the bathroom heating ventilation drying apparatus 1E receives the water dripped from the air passage opening / closing damper 6C in the half-open position P3, the closed position P1 of the air passage opening / closing damper 6C on the inner surface of the front panel 11. The water receiving portion 11j may be provided at a predetermined position facing the position N1 of the side portion 63 at the position N3 and the position N3 of the side portion 63 at the half-open position P3 of the air passage opening / closing damper 6C.

  On the other hand, if the bathroom heating / ventilating / drying apparatus 1E receives water dropped from the air path opening / closing damper 6C at the half-open position P3 and water dropped from the air path opening / closing damper 6C at the open position P2, the front panel 11, the position N1 of the side 63 at the closed position P1 of the air path opening / closing damper 6C and the position N2 opposite to the lower end position N2 of the side 63 at the opening position P2 of the air path opening / closing damper 6C. What is necessary is just to set it as the structure which provides the water receiving part 11j.

  In the example of FIG. 13, the water receiving portion 11 j is provided on the front panel 11, but the water receiving portion may be provided on the apparatus main body 10 side. For example, the circulation fan case 22 or a part of the main body case portion 22e constituting a part of the circulation fan case 22 is projected into the ventilation suction port 15 in a form in which the opening of the ventilation suction port 15 is secured. . Thereby, it is good also as a structure which provides a water-receiving part in the position which opposes the position N3 of the edge part 63 in the half-open position P3 of the air path opening / closing damper 6C.

  FIG. 14 is an internal configuration diagram illustrating a modified example of the bathroom heating / ventilating / drying apparatus according to another embodiment.
