Description

  The present invention relates to a bathroom heater / dryer with a dehumidifying function, and more specifically to a bathroom heater / dryer with a dehumidifying function that has a dehumidifying function for lowering the humidity in the bathroom in addition to the function of ventilating and heating the bathroom.

  In general homes and the like, bathroom heating dryers installed in bathrooms are becoming popular. By heating the bathroom, for example, even when the outside air temperature is low, such as in winter, a rapid change in temperature can be suppressed and comfortable bathing can be performed. Also, by ventilating and flowing cool air, you can enjoy a comfortable bathing in the summer and prevent mold in the bathroom. Furthermore, the clothes can be washed at any time regardless of the weather by drying in the bathroom.

By the way, it is desirable to add a dehumidifying function to the bathroom heater / dryer in consideration of the fact that the interior of the bathroom is a high humidity space and that clothes are more efficiently dried. As a means for realizing such a dehumidifying function, for example, a technique has been proposed in which moisture in the bathroom is adsorbed using an adsorbent such as zeolite or silica gel, and is regenerated and released outside the bathroom (for example, Patent Documents). 1 and 2).
Japanese Patent Laid-Open No. 9-225249 Japanese Patent Laid-Open No. 11-4998

However, when the dehumidifying function is added, the size of the bathroom heater / dryer increases accordingly.
On the other hand, in order to increase the versatility of installing the bathroom heater / dryer, there is a condition that it must be as slim and compact as possible. If the bathroom is adjacent to the outer wall of the building, a bathroom heater / dryer may be attached to the outer wall and communicated with the bathroom through the vent. However, in actual detached houses and condominiums, the bathroom is often not necessarily adjacent to the outer wall of the building. Therefore, in order to meet a wide range of needs, the bathroom heater / dryer must be sized to be accommodated in the space behind the ceiling of the bathroom. However, the space behind the bathroom ceiling is very limited. In addition to adding a dehumidifying function, it is necessary to make a large breakthrough technically in order to be able to be accommodated in a limited space behind the ceiling of the bathroom while suppressing protrusions in the bathroom and to maintain dehumidification performance. It was.

  This invention is made | formed based on recognition of this subject, The objective is to provide the bathroom heating dryer with a dehumidification function which was slim and compact and maintained the dehumidification performance to the high level.

  The present invention has been made on the basis of recognition of such a problem, and its purpose is to add a dehumidifying function, and to be slim and compact, with a dehumidifying function and a bathroom heating and drying function maintained at a high level such as a blowing capacity. Is to provide a machine.

In order to achieve the above object, according to one aspect of the present invention,
A dehumidifying rotor having first and second main surfaces forming front and back surfaces;
A circulation air passage that introduces air in the bathroom to the first main surface of the dehumidification rotor and allows the air to be circulated into the bathroom by taking out from the second main surface;
A regenerative air passage that introduces air in the bathroom into the first main surface of the dehumidification rotor, takes out the air from the second main surface, and discharges the air out of the bathroom;
With
There is provided a bathroom heating dryer with a dehumidifying function, wherein a flow direction of the circulation air passage passing through the dehumidification rotor and a flow direction of the regenerating air passage passing through the dehumidification rotor are the same. .

  According to the said structure, a slim and compact bathroom heating dryer with a dehumidification function can be provided, adding a dehumidification function. That is, both the circulation air path and the regenerative air path introduce air into the same first main surface facing the bathroom side of the dehumidification rotor and take it out from the same second main surface. When supplying to a dehumidification rotor as reproduction | regeneration wind, an air path can be comprised short and without bending. Therefore, since the ventilation capacity of the fan motor for circulating air and the fan motor for regenerative air can be lowered, the fan can be reduced in size, and a slim and compact bathroom heating dryer with a dehumidifying function can be provided. it can.

  Here, the regeneration air passage may be provided with a regeneration heater provided upstream of the dehumidification rotor and a circulation fan and a regeneration fan downstream of the dehumidification rotor.

That is, in the regeneration efficiency of a dehumidification rotor, when regeneration is performed by adding a certain amount of heat to a dehumidification rotor having a certain thickness, there are wind speed values with a high regeneration efficiency and a large wind speed distribution. As a result, the regeneration efficiency of the entire dehumidifying rotor also decreases. In particular, when a PTC (positive temperature coefficient) heater is used as the regenerative heater, the heat generation characteristics of the PTC heater depend on the wind speed, so that the regeneration efficiency of the dehumidifying rotor is further deteriorated when the wind speed distribution is large. However, according to the present invention, since the pressure distribution on the entire surface of the dehumidification rotor can be made uniform, it is possible to make the wind speed distribution of the regenerated wind to the dehumidification rotor uniform and the wind speed distribution of the circulating wind, and the regeneration efficiency and dehumidification efficiency are increased. it can. Therefore, it is possible to propose a bathroom dryer with a dehumidifying function that is slim and compact and maintains high dehumidifying performance.

  In addition, the wind leakage from the regenerative air passage to the circulation air passage results in a decrease in regeneration efficiency due to regenerative heat leak and a decrease in dehumidification efficiency due to humid air leak. By reducing the pressure difference, the pressure balance between the two air passages can be achieved, and the amount of wind leakage between the circulation air passage near the dehumidification rotor and the clearance of the regeneration air passage can be reduced. Efficiency and dehumidification efficiency can be increased.

  Further, the regeneration air passage has a suction port opened toward the bathroom, and the regeneration heater is disposed at a position where air sucked from the suction port is introduced without being bent. Can be.

As a result, the pressure distribution difference due to the bending of the air sucked from the suction port can be eliminated, so that the air can flow uniformly to the dehumidifying rotor and the regeneration efficiency can be increased.
In addition, since the air resistance due to the bending of the air can be reduced, the air blowing capacity of the fan motor for circulating air and the fan motor for regenerative air can be lowered, and the fan can be downsized. In addition, a compact bathroom heater / dryer with a dehumidifying function can be provided.

  Here, the circulation air passage may be provided with a circulation fan provided on the downstream side of the dehumidification rotor and a heating heater provided on the downstream side of the circulation fan.

  As a result, the air in the bathroom is sucked by the circulation fan, heated by the heater, and sent out again into the bathroom to warm and dry the bathroom, as well as by the circulation fan provided downstream of the dehumidification rotor. Since the air sucked from the bathroom is passed through the warmed dehumidification rotor and this air is reheated by the heater, the drying performance can be further improved.

  According to the invention of the present application, it is possible to provide a bathroom heating dryer with a dehumidifying function that is slim and compact while maintaining a high level of performance such as an air blowing capacity while adding a dehumidifying function, and the industrial merit is great. is there.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a conceptual diagram illustrating the overall configuration of a bathroom heating dryer with a dehumidifying function according to an embodiment of the present invention.
That is, the bathroom heater / dryer 1 with a dehumidifying function of the present embodiment includes a circulation air passage 100 and a regenerative air passage 200 that respectively pass through the dehumidification rotor 10. The circulation air passage 100 is provided with a circulation fan 20 provided on the downstream side of the dehumidification rotor 10 and a heating heater 30 provided on the downstream side thereof. The circulation fan 20 sucks the air in the bathroom through the dehumidification rotor 10 and sends it out through the heater 30 into the bathroom. The air path is as shown by arrows A, B, C, and D in FIG. By heating the heater 30, the inside of the bathroom can be heated. A damper 70 is provided between the circulation fan 20 and the heater 30. By opening the damper 70 as appropriate, the air in the bathroom sucked by the circulation fan 20 can be discharged to the outside through the exhaust duct as indicated by the arrow E. That is, ventilation in the bathroom is possible.

On the other hand, the regeneration air passage 200 is provided with a regeneration heater 40 on the upstream side of the dehumidification rotor 10 and a regeneration fan 50 on the downstream side of the dehumidification rotor 10. As represented by arrows F, G, and H, when the air is sucked by the regeneration fan 50, the heated air passes through the dehumidification rotor 10, and moisture is evaporated from the dehumidification rotor 10 containing moisture to thereby dehumidify the rotor 10. Playback is possible.
The dehumidifying rotor 10 can be rotated as necessary by the rotor rotating motor 60.

  Here, FIG. 1 is a schematic diagram showing an air flow path for convenience of explanation. In an actual bathroom heating dryer with a dehumidifying function, the circulation air path 100 and the regeneration air path 200 are dehumidified. Viewed from the rotor 10, it extends in substantially the same direction. The dehumidifying rotor 10 faces the bathroom and is fitted and disposed in a suction port for sucking air in the bathroom.

  FIG.2 and FIG.3 is a partially cut perspective view for demonstrating the structure of the actual bathroom heating dryer 1 with a dehumidification function. That is, FIG. 2 is a perspective view of the bathroom heater / dryer 1 with a dehumidifying function as viewed from the front side, and FIG. 3 is a perspective view of the bathroom heater / dryer 1 as viewed from the back side.

  As shown in these drawings, by providing the circulation fan 20 on the upper side of the dehumidifying rotor 10 provided on the intake port 5, the bathroom heating dryer with a dehumidifying function can be made slim and compact. In an actual bathroom heating / drying machine with a dehumidifying function, the circulation fan 20 and the regeneration fan 50 are not axial fans (propeller fans) but are so-called sirocco fans. By using a sirocco fan, the thickness can be kept slim while securing a particularly large air flow.

  As shown in FIG. 2, a circulation air passage 100 is formed on the front side of the apparatus, and a regeneration air passage 200 is formed on the back side of the apparatus as shown in FIG. That is, the regeneration fan 50 (FIG. 3) is arranged on the back side of the heater 30 (FIG. 2). The circulation air passage 100 and the regeneration air passage 200 are partitioned by a partition 15 at the upper portion of the dehumidifying rotor 10.

  Drawing 4 is a key map showing arrangement of an element in a bathroom heating dryer with a dehumidification function of this embodiment. In this figure, the same elements as those described above with reference to FIGS. 1 to 3 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The dehumidifying rotor 10 is made of, for example, ceramic paper having a honeycomb structure, and a hygroscopic material such as zeolite or silica gel is supported on the surface thereof. The dehumidifying rotor 10 has a diameter of, for example, about 150 to 300 millimeters and a thickness of about 15 to 50 millimeters.

Further, as the heater 30 and the regenerative heater 40, it is desirable to use a PTC (positive temperature coefficient) heater from the viewpoint of safety and the like. The PTC heater has a self-temperature controllability because the electrical resistance value of the resistor increases as the temperature rises.

  During the dehumidifying operation, the air in the bathroom is sucked by the circulation fan 20 while rotating the dehumidifying rotor 10 in the direction of arrow R (or the opposite direction). The rotation speed can be, for example, about 0.5 rotations per minute. As shown in the flow of the arrow A through the dehumidifying rotor 10, the air containing moisture sucked from the bathroom is dehumidified by the hygroscopic material supported on the surface when passing through the dehumidifying rotor 10, and the dried air is It is sent into the bathroom via the circulation air passage 100.

  At this time, the regeneration heater 40 is heated and suctioned by the regeneration fan 50, whereby the regeneration processing of the dehumidifying rotor 10 is also executed. That is, by passing the air in the bathroom heated by the regenerative heater 40 through the dehumidifying rotor 10, the moisture absorbed by the hygroscopic material on the surface of the dehumidifying rotor 10 is released. The air containing moisture is discharged to the outside through the regeneration air passage 200.

  Thus, the inside of the bathroom can be dehumidified continuously by dehumidifying in the circulation air passage 100 and regenerating in the regeneration air passage 200 while rotating the dehumidification rotor 10.

  In the present embodiment, as shown in FIG. 4, the flow directions of the circulation air passage 100 and the regeneration air passage 200 that pass through the dehumidification rotor 10 are the same. That is, in the circulation air passage 100, air passes in the direction indicated by the arrows A and B by the circulation fan 20 provided on the downstream side of the dehumidification rotor 10. On the other hand, also in the regeneration air passage 200, air passes in the direction indicated by the arrows F and G by the regeneration fan 50 provided on the downstream side of the dehumidifying rotor 10.

  Thus, by making the flow of air passing through the dehumidification rotor 10 in the same direction, air leakage in the partition 15 can be reduced. That is, it is necessary to provide a certain gap (clearance) between the dehumidification rotor 10 and the partition 15 so as not to hinder the smooth rotation of the dehumidification rotor 10. However, if air leaks here, there arises a problem that the efficiency of dehumidification and regeneration is reduced.

  FIG. 5 is a schematic view illustrating a dehumidifying mechanism of a comparative example examined by the present inventors. That is, in the case of this comparative example, the air flow in the circulation air passage 100 (arrow A) and the heated air flow in the regeneration air passage 200 (arrow F) are in opposite directions in the dehumidifying rotor 10. That is, the circulation fan 20 and the regeneration fan 50 are provided on the opposite side across the dehumidification rotor 10 and suck air in the opposite directions. In this way, the pressure difference between the circulation air passage 100 and the regeneration air passage 200 is increased. For example, since pressure loss occurs in the dehumidifying rotor 10, the pressure P 1 on the upstream side of the dehumidifying rotor 10 in the circulation air path 100 is higher than the pressure P 2 on the downstream side of the regeneration air path 200. For this reason, air leaks in the direction of the arrow L1 in the gap of the partition 15.

  Similarly, the pressure P3 on the downstream side of the dehumidification rotor 10 in the circulation air path 100 is lower than the pressure P4 on the upstream side of the regeneration air path 200. For this reason, air leaks in the direction of the arrow L2 in the gap of the partition 15.

  Thus, when a leak occurs in the partition 15, the efficiency of dehumidification and regeneration decreases. In other words, when a leak occurs in the direction of the arrow L2, the regeneration heating air is mixed into the circulation air passage 100, and the regeneration heat to the dehumidification rotor 10 is decreased. Therefore, the regeneration efficiency and the dehumidification efficiency are decreased.

  On the other hand, according to the present invention, as shown in FIG. 4, the air flow in the dehumidification rotor 10 of the circulation air passage 100 and the regenerative air passage 200 is in the same direction. If it does in this way, the pressure loss in the dehumidification rotor 10 will also generate | occur | produce in the same direction, and the difference of the pressure of the circulation air path 100 and the reproduction | regeneration air path 200 becomes small. That is, the difference between the pressure P1 of the circulation air passage 100 and the pressure P2 of the regeneration air passage 200 is small, and the occurrence of leakage in the gap of the partition 15 can be suppressed. As a result, it is possible to prevent the dehumidification efficiency and the regeneration efficiency from being lowered and to operate efficiently.

  In addition, according to the present invention, the circulation fan 20 and the regeneration fan 50 can be both slimmed down and made compact by arranging the circulation fan 20 and the regeneration fan 50 on one side of the dehumidification rotor 10 so as to be vertically stacked. it can.

  Furthermore, according to the present invention, air is uniformly taken into the dehumidification rotor and the regenerative heater 40 by setting the air flow in the dehumidification rotor 10 of the circulation air path 100 and the regenerative air path 200 in the same direction. Since the air is uniformly taken into 40, the regenerated air heated uniformly can be sent to the dehumidifying rotor 10.

  FIG. 6 is a schematic view illustrating a bathroom heating dryer with a dehumidifying function of a comparative example examined by the present inventors. That is, in the case of this comparative example, the air flow in the circulation air passage 100 and the regeneration air passage 200 is in the opposite direction in the dehumidifying rotor 10.

  If it does in this way, it will be necessary to provide the channel of the secondary side of regeneration air channel 200 below dehumidification rotor 10, and the thickness (the size of the up-and-down direction in a figure) will increase. In addition, the size of the dehumidifying rotor 10 is limited in order to secure a space for the bent regeneration air passage 200. The fact that the size of the dehumidifying rotor 10 is limited means that the dehumidifying performance is lowered.

  On the other hand, according to the present invention, as illustrated in FIGS. 1 to 4, it is only necessary to provide the thin regenerative heater 40 on the lower side of the dehumidifying rotor 10, and all other elements are the dehumidifying rotor 10. The thickness of the apparatus can be made slim by disposing it on the upper side. Furthermore, the size of the dehumidifying rotor 10 can be maximized. As a result, high dehumidification performance is obtained.

  Furthermore, in the case of the comparative example of FIG. 6, the flow path on the primary side of the regeneration air path 200 must be bent above the dehumidification rotor 10. However, if the flow path is bent in this manner, the pressure loss increases and the air flow rate distribution becomes non-uniform. Then, the regenerative heater 40 is not heated uniformly, and temperature unevenness is likely to occur. This is particularly noticeable when a PTC heater is used. As a result, there arises a problem that the reproduction efficiency tends to decrease.

  On the other hand, according to the present invention, as shown in FIG. 4, the flow of the circulation air passage 100 and the flow of the regenerative air passage 200 are set in the same direction in the dehumidification rotor 10, so that the upstream side of the dehumidification rotor 10. Can be opened toward the bathroom space, and air can be taken in with a uniform flow distribution without causing pressure loss. As a result, the regeneration heater 40 can be heated uniformly, and heated air having a uniform temperature can be sent to the dehumidifying rotor 10 to increase the regeneration efficiency.

Hereinafter, the bathroom heating dryer with a dehumidifying function according to the embodiment of the present invention will be described in more detail while illustrating specific examples.
FIG. 7 is a schematic view illustrating a state in which the bathroom heater / dryer with a dehumidifying function of this embodiment is installed in a bathroom.
According to the present invention, the flow direction of the circulation air passage 100 and the regeneration air passage 200 passing through the dehumidification rotor 10 is the same direction, and the circulation fan 20 and the regeneration fan 50 are disposed on the upper side of the dehumidification rotor 10, thereby dehumidifying. The thickness of the function bathroom heater / dryer 1 can be made slim and the size can be made compact.
As a result, as illustrated in FIG. 7, it can be installed behind the ceiling of many bathrooms 400 installed in a detached house or apartment. And by utilizing the dehumidifying function, the laundry can be dried quickly and the mold in the bathroom can be effectively suppressed.

FIG. 8 is a schematic view illustrating an operation panel of a remote controller for operating the bathroom heater / dryer with a dehumidifying function of this embodiment.
That is, the bathroom heater / dryer with a dehumidifying function of the present embodiment has operation modes such as “ventilation”, “clothing drying”, “bathroom dehumidification”, “heating”, “cool wind”, and the like. Hereinafter, each operation mode will be described.

FIG. 9 is a schematic diagram illustrating an operation mode of “ventilation”.
That is, in the “ventilation” mode, the damper 70 is opened and the circulation air passage 100 is blocked. By rotating the circulation fan 20 in this state, the air in the bathroom is discharged to an exhaust duct (not shown) along the paths indicated by arrows A, B, C, and E. For example, fresh outside air is introduced into the bathroom through ventilation slits provided in windows and doors, and is ventilated. At this time, the regeneration heater 40 and the regeneration fan 50 are not operated.

FIG. 10 is a schematic diagram illustrating one mode of operation modes of “clothing drying” and “bathroom dehumidification”.
That is, in this aspect, the damper 70 is closed and the air in the bathroom circulates through the circulation air passage 100. At this time, the heater 30 may be energized as appropriate. Further, the regeneration heater 40 is energized, and the regeneration fan 50 is rotated while the dehumidifying rotor 10 is rotated. That is, the dehumidifying function using the dehumidifying rotor 10 is operated with the damper 70 closed.

FIG. 11 is a schematic diagram illustrating another aspect of the operation modes of “clothing drying” and “bathroom dehumidification”. That is, in this aspect, the damper 70 is in a half-open state. Then, the heater 30 is energized and the circulation fan 20 is turned. At this time, the regeneration heater 40 and the regeneration fan 50 are not operated. In other words, the bathroom is heated while ventilating.
The operation mode illustrated in FIG. 10 and the operation mode illustrated in FIG. 11 can be appropriately used depending on, for example, the relative humidity in the bathroom. For example, a humidity sensor is provided in a bathroom heater / dryer with a dehumidifying function, and when the relative humidity is 60% or less, the operation mode shown in FIG. 10 is selected, and when the relative humidity exceeds 60%, it is shown in FIG. It is possible to select the operation mode. This is because when the relative humidity is high, it is possible to lower the humidity more rapidly by using both ventilation and heating than when using the dehumidifying function.

  FIG. 12 is a schematic diagram illustrating an operation mode of “heating”.

  That is, in this aspect, the damper 70 is fully closed. Then, the heater 30 is energized and the circulation fan 20 is turned. Also at this time, the regeneration heater 40 and the regeneration fan 50 are not operated. That is, heating is performed by circulating hot air in the bathroom.

  FIG. 13 is a schematic diagram illustrating an operation mode of “cool wind”.

That is, in this aspect, the damper 70 is in a half-open state. Then, the circulation fan 20 is rotated without energizing the heater 30. Also at this time, the regeneration heater 40 and the regeneration fan 50 are not operated. In other words, cool air is circulated while partially ventilating the bathroom.
As described above, according to the present invention, the direction of the circulation air passage 100 through which the dehumidification rotor 10 passes and the direction of the regeneration air passage 200 are the same, and the regeneration fan 50 is disposed on the upper side of the dehumidification rotor 10. In addition to the conventional “ventilation”, “clothing drying”, “heating” and “cool air” operation modes, the “drying clothing” and “bathroom dehumidification” operation modes have been added. Is possible.

Hereinafter, various structures studied by the inventor in the course of reaching the present invention will be described.
FIGS. 14 to 16 are schematic views showing the structure of a bathroom heater / dryer with a dehumidifying function of a comparative example examined by the inventor in the course of reaching the present invention. In these drawings, the same elements as those described above with reference to FIGS. 1 to 13 are denoted by the same reference numerals, and detailed description thereof is omitted.
In the case of the comparative example (plan A) shown in FIG. 14, the flow of the circulation air passage 100 flowing through the dehumidification rotor 10 and the flow of the regeneration air passage 200 are in the same direction. However, the regeneration fan 50 is provided on the upstream side of the regeneration heater 40, and the air sucked by the regeneration fan 50 is bent and supplied to the regeneration heater 40 as indicated by an arrow F.
Next, in the case of the comparative example (plan B) shown in FIG. 15, the flow of the circulation air passage 100 flowing through the dehumidification rotor 10 and the flow of the regeneration air passage 200 are in opposite directions. The regeneration fan 50 is provided below the dehumidifying rotor 10.

Next, also in the comparative example (C plan) shown in FIG. 16, the flow of the circulation air passage 100 flowing through the dehumidification rotor 10 and the flow of the regeneration air passage 200 are in opposite directions. The regeneration fan 50 is provided on the upstream side of the regeneration heater 40, and the air sucked by the regeneration fan 50 is bent and supplied to the regeneration heater 40 as indicated by an arrow F.
The inventor of the present application conducts a dehumidification test on the A, B, and C plans described above with reference to FIGS. 14 to 16 and the bathroom heating dryer with a dehumidifying function according to the embodiment of the present invention shown in FIG. Carried out. The test conditions are as follows.

Dehumidification rotor diameter: 270 mm Dehumidification rotor thickness: 26 mm Dehumidification rotor cell number: 320 cells Dehumidification rotor moisture-absorbing material: Zeolite circulating air volume: 150 m ³ / hour Regenerative air volume: 20 m ³ / hour Regenerative heat capacity: 700 Watts

The dehumidification amount and the voltage of the regeneration fan obtained in the present invention and each comparative example are summarized below.

  As can be seen from the results, according to the present invention, the dehumidifying ability is 1.3 to 3 times as much as the A, B, and C plans, and the regeneration fan voltage is about 86 to 56 percent. It was confirmed that it can be lowered.

  As described above with reference to FIG. 4, the high dehumidification capability in the present invention is that the air flow in the dehumidification rotor 10 of the circulation air passage 100 and the regeneration air passage 200 is in the same direction, so that the gap of the partition 15 This is considered to be because it is possible to suppress the occurrence of leakage in the water and prevent the dehumidification efficiency and the regeneration efficiency from being lowered and to operate efficiently.

  Further, according to the present invention, by not bending the flow path leading to the regenerative heater 40 as in the case of the A and C plans, the flow velocity distribution of the air in the regenerative heater 40 can be made uniform, and the temperature can be uniform without temperature unevenness. It is also possible to increase regeneration efficiency by supplying regeneration heating air to the dehumidifying rotor 10.

  On the other hand, according to the present invention, the circulation fan 20 and the regenerative fan 50 are both disposed on one side of the dehumidification rotor 10, so that the bathroom heating dryer with a dehumidifying function is provided as compared with the A, B, and C plans. Can be made slim and compact.

  FIG. 17 is a schematic diagram showing another specific example of the bathroom heating dryer with a dehumidifying function of the present invention. Also in this figure, the same elements as those described above with reference to FIGS. 1 to 13 are denoted by the same reference numerals, and detailed description thereof is omitted.

  This specific example is a bathroom heating dryer with a dehumidifying function that also serves as a so-called regular ventilation facility. That is, based on the Building Standard Law, a ventilation amount of 0.5 times the residential space volume per hour is required. In the case of this example, a ventilation / regeneration fan 50 is provided to suck both the toilet and / or the toilet, and also suck the regeneration air.

  FIG. 18 is a schematic diagram showing the overall configuration of a specific example in which the bathroom heating dryer with a dehumidifying function of the present invention is a two-room ventilation type.

  In this specific example, an air passage I is connected to a space between the dehumidification rotor 10 and the circulation fan 20, and a two-room ventilation shutter 85 that opens and closes the communication passage to the air passage I is provided. When the circulation fan 20 performs a suction operation, the pressure between the dehumidification rotor 10 and the circulation fan 20 becomes negative due to the pressure loss of the dehumidification rotor 10. Therefore, by opening the two-room ventilation shutter 85, a room other than the bathroom, such as a washroom, can be easily ventilated via the air passage I. In this specific example, the two-room ventilation shutter 85 is opened only when two rooms are ventilated, and the two-room ventilation shutter 85 is closed during operations such as drying and heating.

  FIG. 19 is a schematic diagram showing the overall configuration of a specific example in which a bypass air passage is provided in the bathroom heating dryer with a dehumidifying function of the present invention.

In this specific example, a bypass air passage J is provided in parallel with the dehumidification rotor 10, and a bypass ventilation shutter 90 that opens and closes the air passage J is provided.
When the pressure loss of the dehumidification rotor 10 is large, the ventilation capacity of the circulation fan 20 may be insufficient, or noise due to the circulation fan 20 may increase. According to this specific example, in such a case, by opening the bypass ventilation shutter 90 and performing suction through the bypass air passage J, these problems can be solved.

  FIG. 20 is a schematic view illustrating a state in which the bathroom heating dryer with a dehumidifying function of this example is installed.

  That is, the bathroom heater / dryer 1 with a dehumidifying function is installed behind the ceiling of the bathroom 400. Then, the space between the washroom 500 and the toilet 600 is always sucked through the intake ducts 702 and 704 for 24 hours. The sucked air is discharged outside the room through the exhaust duct 706.

Returning to FIG. 17 again, the description will be continued. In this specific example, a ventilation shutter 80 and a reproduction shutter 82 are provided. When the dehumidifying rotor 10 is regenerated, the regeneration shutter 82 is opened and the interior of the bathroom is sucked by the ventilation / regeneration fan 50.
Further, in the specific example described above with reference to FIGS. 11 and 13, the ventilation shutter 80 is opened in this specific example, corresponding to the operation of opening the damper 70. That is, when the ventilation shutter 80 is opened, the air in the bathroom is sucked by the ventilation / regeneration fan 50 and can be ventilated.

  As described above, according to this specific example, by using both a constantly ventilated facility and a bathroom heater / dryer with a dehumidifying function, the heating and dehumidification of the bathroom is maintained while keeping the air in the residential space always clean. Is possible.
