Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0032]
(Embodiment 1)
FIG. 1 is a schematic diagram showing an overall configuration of a bathroom heating / drying machine 10 according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view of the main part in FIG. 1, and FIG. 3 is a plan view of the main part in FIG. 1 to 3, a bathroom heating / drying machine 10 includes a circulation box 11 that sucks air in the bathroom, exchanges heat, and circulates the air again in the bathroom, and a ventilation box 21 that ventilates air in the bathroom, a dressing room, a toilet, and the like. Constructed and usually installed behind the ceiling of a bathroom.
[0033]
The circulation box 11 is installed on the ceiling plate 12, and has a suction port 81 and a blowout port 82 on the wall surface 80 of the first casing 8 facing the bathroom. A hole 13 is formed in the ceiling plate 12 at a position corresponding to the suction port 81 and the outlet 82 of the circulation box 11, and the grill 14 is fitted below the hole 13. The grill 14 is provided with a suction louver 141 on the suction port 81 side and a blowout louver 142 on the blowout port 82 side. Ventilation holes 83, 84, 85 and 88 are formed on the four side surfaces of the first casing 8.
[0034]
A ventilation box 21 is provided through the fixed plate 20 so as to communicate with one of the ventilation openings 83. A ventilation port 201 is formed at the center of the fixed plate 20, and a ventilation port 91 is also provided in the ventilation box 21 so as to communicate with the ventilation ports 83, 201, and each circulation box 11 is connected to the ventilation box 11 via the fixed plate 20. It is fixed with bolts and nuts so that the ports 83, 91, 201 communicate with each other. Details will be described later. The ventilation box 21 is provided with a damper 19 that is rotated by a stepping motor 26 in order to open and close the vent 91. The ventilation openings 84, 85, 88 other than the ventilation opening 83 are blocked by the lids 86, 87, 89. The reason why the vent holes 83, 84, 85, 88 are formed on the four side surfaces of the first casing 8 will be described later.
[0035]
Two air passages 17 and 18 are formed in the first casing 8. The first air passage 17 guides air sucked from the suction port 81 to the air outlet 82 via the circulation fan 16 that is rotated by the heat exchanger 15 and the circulation motor 27, and the second air passage 18 is the suction port. This is an air path that allows the air sucked from 81 to pass through the circulation box 11 without passing through the heat exchanger 15 and the circulation fan 16, and leads from the damper 19 to the ventilation box 21 through the vent holes 83, 201, 92. . The heat exchanger 15 is formed in a bending coil shape, and is formed so as to have a larger suction area than the straight shape.
[0036]
The ventilation box 21 incorporates a ventilation fan 23 that is rotated by a ventilation motor 22 in the second casing 9, and suction ports 24 and 26 and an exhaust port 25 are provided on two opposite side walls of the second casing 9. ing. The suction ports 24 and 26 and the exhaust port 25 are for ventilating a room that does not face the grill 14, and suction ducts 241 and 261 are connected to the suction ports 24 and 26, for example, a dressing room or a toilet. Connected to ventilating room ventilated room. An exhaust duct 251 is connected to the exhaust port 25, and is connected to an outdoor exhaust port. On the outer surface of the other side wall of the second casing 9, an electrical box in which a printed circuit board 301 and a terminal block 302 for driving the heat exchanger 15, the circulation motor 27, the stepping motor 26 and the ventilation motor 22 are incorporated in the casing. 30 is provided.
[0037]
Signal lines connecting the electrical box 30 and the heat exchanger 15, the circulation motor 27, the stepping motor 26, and the ventilation motor 22 are not shown.
[0038]
Next, the operation will be described. In the case of heating the bathroom, the air in the bathroom sucked from the louver 141 and the suction port 81 of the circulation box 11 is heat-exchanged by the heat exchanger 15 according to the air passage 17 and the temperature is increased. Is circulated through the louver 142 into the bathroom. At this time, it does not matter whether the damper 19 is closed or open.
[0039]
In this operation, since the heat exchanger 15 is formed in a bending coil shape as described above, the suction area is larger than that of the straight shape, and therefore the heat exchange capability is increased, so that the flow rate is increased even if the amount of intake air is the same. Since it can be reduced, noise can be reduced.
[0040]
When the damper 19 is closed, the operation of the ventilation motor 22 is optional, but by operating the ventilation motor 22, the air from the dressing room and the toilet communicated with the suction ports 24, 26 is supplied to the suction ports 24, 26. Then, the air can be ventilated by being exhausted from the exhaust port 25 to the outside by the ventilation fan 23.
[0041]
On the other hand, when the inside of the bathroom is ventilated, the air inside the bathroom sucked from the louver 141 and the suction port 81 of the circulation box 11 is not passed through the heat exchanger 15 and the circulation fan 16 in the circulation box 11 according to the air passage 18. Then, the damper 19 is opened and introduced into the ventilation box 21. In the ventilation box 21, the introduced air in the bathroom is sent to the exhaust port 25 by the ventilation fan 23 and exhausted to the outside to ventilate and dry the bathroom. At this time, dampers (not shown) are provided in the suction ports 24 and 26 of the ventilation box 21, and if the dampers are open, ventilation of other rooms such as a dressing room and a toilet communicating with the suction ports 24 and 26 is performed at the same time. If the damper is closed, only the inside of the bathroom facing the grill 14 is ventilated and dried.
[0042]
In addition, when drying laundry etc. in a bathroom, heating operation and ventilation operation can be performed simultaneously or alternately.
[0043]
For controlling and switching these operations, a control signal is sent to the electrical equipment box 30 by a signal line (not shown) by a remote controller (not shown) to drive the control circuit.
[0044]
In the present embodiment, the electrical box 30 is provided on the outer wall of the ventilation box 21. Therefore, since high-humidity air does not pass around the control circuit, the reliability of the control circuit system is improved.
[0045]
Further, since there is no electrical box 30 in the circulation box 11, the air passages 17 and 18 can be widened. For this reason, even with the same air volume, the flow velocity of the air passing through the circulation box 11 can be reduced, and noise can be reduced. Further, the volume of the circulation box 11 can be reduced by the amount without the electrical box 30.
[0046]
Moreover, since the inspection port 33 of the bathroom heating dryer 10 installed in the back of the ceiling is usually provided on the ventilation box 21 side, the work of connecting the power line 32 to the terminal block 302 and the electrical circuit system of the electrical box 30 are maintained and inspected. When repairing, it is possible to work simply by putting the upper body through the inspection port 33 without going up to the back of the ceiling.
[0047]
By the way, as described above, the bathroom heater / dryer 10 is usually installed behind the ceiling, but in recent years, an increasing number of houses have the bathroom ceiling as a dome ceiling. In this case, the ventilation box 21 is often obstructed by the dome ceiling depending on the location and shape of the dome and is often difficult to install. In this case, in FIG. 1, the fixing plate 20 and the ventilation box 21 are moved to the positions of the ventilation openings 84, 85, 88 other than the ventilation openings 83, and the ventilation openings 83 are covered with the lids 85, 86, 89. In this way, the positions of the ventilation openings 83, 84, 85, 88 are formed on the four side surfaces of the circulation box 11, and the unused ventilation openings 83, 84, 85 are covered and covered with the lids 85, 86, 89. Since the ventilation box 21 can be installed in the four directions of the circulation box 11, the ventilation box 21 can be installed freely without being subjected to various restrictions on the shape of the ceiling and the space.
[0048]
The ventilation openings 83, 84, 85, 88 and the lids 85, 86, 89 may not be all on the four side surfaces of the circulation box 11, and may be two or more on one side surface.
[0049]
As the heat exchanger 15, a PTC heater, a hot water coil, a heat pump coil, or the like can be used, and the heat exchanger 15 in the present invention includes these.
[0050]
Further, even if the damper 19 is provided on the circulation box 11 side, the operation effect is not changed.
[0051]
(Embodiment 2)
FIG. 4 is a schematic diagram of a main part in the configuration of the bathroom heating dryer 10 according to Embodiment 2 of the present invention. In FIG. 4, the same parts as those in FIG. In the second embodiment, in order to reduce the thickness and width of the electrical box 30, the electrical box 30 has an inverted L-shaped cross section, and a printed board 301 and a terminal block 302 are placed in a box on each side of the inverted L shape. Stores electrical components such as. The printed circuit board 301 is connected to the ventilation motor 22 of the ventilation box 21 through a signal line 303, and is connected to the connector 305 through a signal line 304. On the other hand, a signal line 306 for driving the heat exchanger 15, the circulation motor 27, and the stepping motor 26 of the circulation box 11 is also connected to the connector 305, and the drive signal controlled by the printed circuit board 301 is the signal line 304, the connector 305, the signal The heat is supplied to the heat exchanger 15, the circulation motor 27, and the stepping motor 26 of the circulation box 11 through the line 306 to drive each of them.
[0052]
Since the thickness of the electrical box 30 can be reduced in the second embodiment, it is possible to prevent the head from hitting when the inspector puts the upper body through the inspection port 33, and the working space at hand can be reduced. Maintenance workability is improved.
[0053]
In addition, when the ventilation motor 22 is a high voltage motor such as an AC motor, the signal line 303 can be prevented from being exposed outside the body in order to comply with the electrical safety law. In this case, if the electrical box 30 is divided into a printed board 303, a terminal block 302 portion, and a signal line 303 portion, workability is improved.
[0054]
(Embodiment 3)
FIG. 5 is a perspective view of a main part in the configuration of the bathroom heating dryer 10 according to Embodiment 3 of the present invention. In FIG. 5, the same parts as those in FIG.

In general houses and the like, ribs 41 and the like are provided on the ceiling plate 12 on the back of the ceiling. If this rib protrudes from the ceiling, the gap between the ventilation box 21 and the ceiling board 12 may become narrow due to the protrusion of the rib 41 when the bathroom heater / dryer 10 is installed behind the ceiling. .
[0056]
In the third embodiment, in order to solve this problem, the fixing plate 20 is moved upward, and the ventilation box 21 is attached to the fixing plate 20 so that the ventilation box 21 is attached to the circulation box 11 by the rib 41. Fix it by shifting up the protruding part. At this time, the ventilation opening 83 of the circulation box 11 is formed in advance so as to be slightly larger in the downward direction, and when the fixing plate 20 and the ventilation box 21 are shifted upward and fixed, the ventilation opening 201 of the fixing plate 20 does not become small. Set to.
[0057]
First, the fixing plate 20 is shifted upward with respect to the circulation box 11 by the protruding amount of the rib 41 and fixed with screws 42, and then formed at the lower end of the ventilation box 21 on the attachment portion 43 provided at the lower end portion of the fixing plate 20. The hole 44 is inserted, and the bolt 45 is passed through the through hole 46 of the ventilation box 21 and fixed with the nut 47 at the upper end of the fixing plate 20. As a result, the rib 41 is positioned below the ventilation box 21, and a sufficient gap between the ventilation box 21 and the ceiling plate 12 can be secured.
[0058]
When the rib 41 is unidirectional as shown in FIG. 5 and there is no obstruction such as the rib 41 on the side of the circulation box 11, the fixing plate 20 and the ventilation box 21 are explained as described in the first embodiment. Of course, it is only necessary to move to the position of the side vents and connect them.
[0059]
Further, when there is a protrusion above the ventilation box 21, the fixing plate 20 may be fixed by being shifted downward with respect to the circulation box 11 so that the ventilation box 21 can be connected.
[0060]
(Embodiment 4)
The fourth embodiment is an operation method related to 24-hour ventilation using the bathroom heater / dryer 10 described with reference to FIGS. 1, 2, and 3.
[0061]
In recent years, it has become a problem that formaldehyde is generated from the building materials of houses and causes allergic asthma. For this reason, a 24-hour ventilation system has been proposed as an indispensable item by a law on so-called promotion of ensuring quality of houses (so-called quality law).
[0062]
In the fourth embodiment, the 24-hour ventilation system is realized by the bathroom heater / dryer 10 described with reference to FIGS. 1, 2, and 3.
[0063]
For example, when air is sucked in from a dressing room which is a room of a house by a duct 241 connected to the suction port 24 of the ventilation box 21 and is continuously exhausted from the exhaust port 25 through the duct 251 by the ventilation fan 23 for 24 hours, Residential 24-hour ventilation is possible.
[0064]
However, if this ventilation operation is performed during bathing, the bathing bath continues to be ventilated, so the bather feels a cold wind and is not preferable.
[0065]
Therefore, in the fourth embodiment, ventilation in the bathroom is stopped while taking a bath, and the ventilation amount is reduced. That is, if the ventilation operation is stopped by the remote controller during bathing, the damper 19 is in a closed state or close to a closed state, and the flow of wind in the bathroom is reduced. On the other hand, if the ventilation of the bathroom at the time of bathing is stopped or the ventilation amount is reduced, the total ventilation air volume in the 24-hour ventilation operation is reduced. Therefore, in order to prevent a decrease in the total ventilation air volume, the ventilation of the bathroom is stopped at the time of bathing, or when the ventilation volume is reduced, other ventilation equipment electrically operated with the bathroom heating dryer 10 is operated during the bathing. Increase ventilation in other rooms.
[0066]
Also, as a reference example, when bathing is stopped during bathing or the ventilation volume is reduced, the ventilation motor 22 speed is increased after bathing to increase the ventilation volume from the bathroom or dressing room. To do.
[0067]
In advance, the total ventilation volume corresponding to the required number of ventilations in 24-hour ventilation of the entire house is set with a remote controller (not shown). Next, the time when the ventilation was stopped during bathing is stored in the EEPROM of the electrical box 30, the ventilation deficit amount is calculated according to the stored value, and the rotation of the ventilation motor 22 after bathing is compensated for the deficit amount on average for 24 hours. Control number and running time. For example, assuming that the ventilation amount at the rotation speed R of the ventilation motor 22 is V and the operation is performed for the operation time T, if the total ventilation amount P corresponding to the required ventilation frequency in 24-hour ventilation is obtained, V × T = P. expressed. In this state, if the ventilation air volume p is decreased by stopping the ventilation of the bathroom for t hours, and the adjustment is performed without changing the operation time T, the rotation speed is adjusted so that the ventilation air volume of the ventilation motor 22 becomes V + p / t. It is controlled so that it is raised for T hours.
[0068]
(Embodiment 5)

[0069]
In order to stop the ventilation operation of the bathroom at the time of bathing in the fourth embodiment, the damper plate 52 comes to the position a and shields the ventilation port 91 of the ventilation box 21 that communicates with the circulation box 11 that communicates with the bathroom. The damper 51 is rotated by the damper motor 53. This rotation control is performed by a remote controller. At this time, since the suction port 24 of the ventilation box 21 is open, ventilation of the dressing room and the like is continued.
[0070]
Next, when the bathing is finished and the bathroom is rapidly ventilated or when the bathroom is dry, the damper 51 is rotated to the position b to open the vent 91 of the ventilation box 21 in order to increase the ventilation air volume from the bathroom. The ventilation operation is performed by shielding the suction port 24 of the ventilation box 21 with the damper plate 52. In this case, it is possible to perform the ventilation operation without stopping the ventilation of the dressing room by slightly shifting the rotational position of the damper 51 from the position b and leaving the suction port 24 a little.
