JP 2003-336875 A

  In the conventional drying apparatus, the air in the indoor space adjacent to the drying chamber is taken into the drying chamber, which affects the temperature and humidity state of the air in the indoor space adjacent to the drying chamber and is adjacent to the drying chamber. There is a problem that the temperature and humidity of the air in the indoor space affects the time until the drying of the drying room is completed.

  For example, as described above, when the drying device is installed in the bathroom and the air in the dressing room is taken into the bathroom, if the dressing room is in a comfortable air-conditioning state, the clothes are undressed to dry the bathroom. The comfortable air conditioning of the room will be impaired.

  In addition, when the dressing room is used after bathing and the humidity in the dressing room is high, when the bathroom is dried, the air in the dressing room with high humidity is introduced into the bathroom, and the bathroom is dried. Will take longer to complete. Furthermore, when a drying operation is performed for a certain time set as a bathroom drying time, if the dressing room is damp, the degree of drying will not be sufficient.

  As described above, the conventional drying apparatus changes the temperature / humidity state of the air-conditioned indoor space adjacent to the drying chamber, and also affects the temperature / humidity state of the air in the indoor space adjacent to the drying chamber. As a drying device, it cannot be said to have good performance.

  In view of the above circumstances, an object of the present invention is to provide a drying apparatus that does not easily interfere with the temperature and humidity state of air in an indoor space adjacent to a drying chamber.

  The first feature of the present invention is a drying system provided with ventilation heating means for heating the sucked air with a heater and ventilating the drying chamber, and exhaust means for sucking the air in the drying chamber and discharging it to the outside. The apparatus is provided with outside air introduction means for introducing outdoor air into the drying chamber.

According to the first feature of the present invention, since the outside air introduction means for introducing outdoor air into the drying chamber is provided, when the drying chamber is dried, the exhaust means sucks the air in the drying chamber and discharges it to the outdoors. In doing so, outdoor air can be introduced. Therefore, the drying chamber can be dried without introducing the air in the adjacent indoor space into the drying chamber, and the drying chamber can be dried without being affected by the temperature and humidity state of the adjacent indoor space. In addition, the drying chamber can be dried without affecting the temperature and humidity state of the adjacent indoor space.
In particular, when the outdoor air is drier than the air in the adjacent indoor space, the time required to make the drying chamber dry is shorter than when the air in the adjacent indoor space is introduced into the drying chamber. can do.
As described above, according to the first feature of the present invention, it is possible to obtain a drying apparatus that hardly interferes with the temperature and humidity state of the air in the indoor space adjacent to the drying chamber.

  A second feature of the present invention is that, in the first feature of the present invention, the outside air introduction means is configured to be switchable between an introduction state and a non-introduction state, and the drying chamber is an adjacent indoor space adjacent to the drying chamber. It is in the point which is provided and provided with the inlet which introduces the air.

According to the 2nd characteristic of this invention, it has the same effect as the 1st characteristic of this invention, and also has the following effects in addition to this.
According to the second feature of the present invention, the outside air introduction means can be switched between the introduction state and the non-introduction state, and the introduction port for introducing the air in the adjacent indoor space is provided in the drying chamber. In the non-introduced state, as the exhaust means sucks the air in the drying chamber and discharges it to the outdoors, the drying chamber is in a negative pressure state, so that the air in the adjacent indoor space is discharged from the inlet. be introduced.
Therefore, when the air in the adjacent indoor space should be introduced when performing the drying operation, the air in the adjacent indoor space can be introduced into the drying chamber by switching the outside air introducing means to the non-introducing state. When outdoor air should be introduced when performing, the outdoor air can be introduced into the drying chamber by switching the outside air introduction means to the introduction state.
For example, when the outdoor air is humid, such as on a rainy day, the outdoor air is not introduced when the dry operation is performed by switching the outside air introduction means to the non-introduction state, and the air in the adjacent indoor space is not introduced. Can be introduced. In addition, if you want to maintain the temperature and humidity environment of the air in the adjacent indoor space that has been made comfortable by air conditioning, do not introduce the air in the adjacent indoor space when performing the drying operation, Can be introduced.
As described above, according to the second feature of the present invention, it is possible to obtain a convenient drying device capable of switching the air introduced into the drying chamber according to the situation when performing the drying operation.

  According to a third feature of the present invention, in the second feature of the present invention, a first temperature / humidity measuring means for measuring the temperature and humidity of air in the adjacent indoor space, and a second temperature for measuring the temperature and humidity of outdoor air. Humidity measurement means, introduction state switching means for switching the outside air introduction means between an introduction state and a non-introduction state, and control means for controlling a drying operation are provided, and the control means measures the first temperature and humidity measurement means. Based on the information and the measurement information of the second temperature / humidity measuring means, the operation of the introduction state switching means is controlled.

According to the 3rd characteristic of this invention, it has the same effect as the 2nd characteristic of this invention, and also has the following effects in addition to this.
According to the third feature of the present invention, the first temperature / humidity measuring means measures the temperature and humidity of the air in the adjacent indoor space, the second temperature / humidity measuring means measures the temperature and humidity of the outdoor air, and the control means Based on the measurement information of the first temperature / humidity measurement means and the measurement information of the second temperature / humidity measurement means, the operation of the introduction state switching means for switching the outside air introduction means between the introduction state and the non-introduction state is controlled. In other words, the operation of the introduction state switching means is controlled based on the temperature and humidity of the air in the adjacent indoor space and the temperature and humidity of the outdoor air, and the outside air introduction means is automatically switched between the introduction state and the non-introduction state. It is done.
Therefore, as a condition when the control means controls the operation of the introduction state switching means, one of air in the adjacent indoor space and outdoor air is selected as air introduced when the drying chamber is dried. If set in this way, the control means selects the appropriate air as the air to be introduced when performing the drying operation based on the measurement information of the first temperature / humidity measurement means and the measurement information of the second temperature / humidity measurement means. As described above, the operation of the introduction state switching means can be controlled.
As a result, when the drying operation is controlled by the control means, even if the temperature and humidity of the air in the adjacent indoor space and the temperature and humidity of the outdoor air change, the air in the adjacent indoor space and the outdoor air Of these, one of the appropriate air is automatically selected for drying the drying chamber.

Therefore, a highly functional drying apparatus can be obtained.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the drying chamber is a bathroom, and the exhaust means sucks and discharges air in an indoor space other than the drying chamber. The exhaust means is provided with a suction action state switching means for switching between an action state in which the other indoor space is sucked and a non-action state in which no suction action is performed, and the control means includes the ventilation heating means and the exhaust means. When the drying operation is performed by operating the, the suction action state switching means is configured to be switched to the non-action state.

According to the 4th characteristic of this invention, it has the same effect as the 3rd characteristic of this invention, and also has the following effects in addition to this.
According to the fourth feature of the present invention, the suction action state switching means can be switched between the action state acting on the other indoor space and the non-action state where the suction action is not performed. The air in the indoor space other than the bathroom is sucked and discharged, and the exhaust means does not suck the air in the indoor space other than the bathroom.
In the non-operating state, since the exhaust capacity of the exhaust means is not used for sucking air in the indoor space other than the bathroom, most of the exhaust capacity of the exhaust means is used for exhausting the bathroom air. Can be effectively discharged.
Accordingly, when it is desired to exhaust air in an indoor space other than the bathroom, the suction action state switching means may be switched to the action state, and when it is not desired to exhaust air in the indoor space other than the bathroom, or the bathroom. When it is desired to effectively discharge the air, the suction action state switching means may be switched to the non-action state. In this way, it is possible to arbitrarily switch whether or not to exhaust the air in the indoor space other than the bathroom.

Further, when the drying operation is performed by operating the ventilation heating unit and the exhaust unit, the control unit switches the suction operation state switching unit to the non-operation state. Therefore, when the drying operation is performed, the control unit is in the non-operation state. That is, when performing a dry operation, the exhaust means effectively discharges the bathroom air.
Therefore, when performing the drying operation, the time required to make the bathroom dry is shortened.
As described above, according to the fourth feature of the present invention, it is possible to arbitrarily switch whether or not to exhaust the air in the indoor space other than the bathroom, and when performing the drying operation, the bathroom is efficiently operated.

Then, based on the command from the remote control operation unit R, the control unit H executes the drying operation when the drying operation switch 20 is turned ON, executes the heating operation when the heating operation switch 21 is turned ON, and cool air operation. When the switch 22 is turned on, the cool air operation is executed, and when the ventilation operation switch 23 is turned on, the ventilation operation is executed.
Below, each driving | operation is demonstrated.

  The drying operation will be described based on the flowcharts shown in FIGS. 4 and 5. When the drying operation switch 20 of the remote control operation unit R is turned ON, the control unit H starts the operation of the heat source device K (step # 1). Then, the circulation fan 8 and the exhaust fan 13 are operated at the operating speed for the drying operation (step # 2), the thermal valve 10 is opened, and the heat medium is passed through the heat exchanger 9 (step). # 3). Then, the bathroom shutter 17 is opened, and the dressing room shutter 18 and the toilet shutter 19 are closed (step # 4).

  As described above, the bathroom heating / drying apparatus switches the undressing room shutter 18 and the toilet shutter 19 as the suction action state switching means to the non-operation state when the ventilation heating means and the exhaust means are operated to perform the drying operation. It is configured as follows. By making the three shutters provided in the exhaust casing 3b in such an open / closed state, the suction action by the exhaust fan 13 acts intensively on the bathroom BR in the drying operation, which is effective. The air in the bathroom BR can be discharged outdoors.

  After the operation of the heat source unit 9, the circulation fan 8 and the exhaust fan 13, and the open / close state of the thermal valve 10, the bathroom shutter 17, the dressing room shutter 18 and the toilet shutter 19 are controlled for the drying operation, again Until the drying operation switch 20 is pushed, an outside air shutter switching process is executed (step # 5 to step # 6).

  As will be described in detail later, the external shutter switching process is a process of switching the open / close state of the outdoor shutter 33 according to the temperature and humidity relationship between the outdoor and indoor (in the present embodiment, the dressing room DR). Opening / closing of the outdoor air shutter 33 is controlled so that air that is suitable for humidity and temperature is introduced into the bathroom BR as air that is introduced into the bathroom when performing a dry operation. . When the outside air shutter switching process is executed in the dry operation, more preferable air is introduced into the bathroom BR by comparing the temperature and humidity of the outdoor air with the temperature and humidity of the air in the dressing room. FIG. 6 shows the correspondence between the inside / outside humidity difference ΔH and the inside / outside temperature difference ΔT and the open / closed state of the outside air shutter 33.

  In the drying operation, the control unit H operates the heat source unit 9 and the heat valve 10 so that the air blown into the bathroom BR from the outlet 5 becomes the target temperature set for the drying operation. Opening and closing is controlled. Further, the direction of the movable louver 11 is adjusted so that the air heated by the heat exchanger 9 is blown out in a direction almost directly below as the drying blowing direction.

  When the drying operation switch 20 is pushed during the drying operation, the control unit H stops the operation of the heat source unit 9 (Step # 7), closes the thermal valve 10 and turns the circulation fan 8 and the exhaust fan. 13 is stopped (step # 8), and the drying operation is terminated.

  Next, the external shutter switching process executed when the drying operation is performed will be described based on the flowchart of FIG.

From the measurement information of the indoor temperature / humidity sensor S1 and the outdoor temperature / humidity sensor S2, the control unit H calculates the difference ΔT between the outdoor humidity value and the indoor humidity value ΔH, and the difference between the outdoor temperature value and the indoor temperature value ΔT. Are calculated (step # 1). The humidity difference ΔH and the temperature difference ΔT at this time are values obtained by subtracting the indoor one from the outdoor one.
When the values of the internal / external humidity difference ΔH and the internal / external temperature difference ΔT are obtained, it is determined whether or not the absolute value of the internal / external humidity difference ΔH is 10% or more (step # 2). If the absolute value of the inside / outside humidity difference ΔH is 10% or more, the open / close state of the outside air shutter 33 is controlled so that the air having the lower humidity is introduced into the bathroom BR. Specifically, whether the value of ΔH is positive or negative is determined (step # 3), and when the value of ΔH is a positive value, that is, when the outdoor humidity is 10% or more higher than the indoor humidity (in FIG. 6). When it corresponds to the environmental state Z1, the outside air shutter 33 is closed (step # 6), and when ΔH is a negative value, that is, when the outdoor humidity is 10% or more lower than the indoor humidity. When it corresponds to the environmental state Z2 in FIG. 6, the outside air shutter 33 is opened (step # 7).

  On the other hand, if the absolute value of the internal / external humidity difference ΔH is smaller than 10 [%], it is determined whether or not the absolute value of the internal / external temperature difference ΔT is 3 [° C.] or more (step # 4). If the absolute value of the inside / outside temperature difference ΔT is 3 ° C. or more, the open / close state of the outside air shutter 33 is controlled so that the higher temperature air is introduced into the bathroom BR. Specifically, whether the value of ΔT is positive or negative is discriminated (step # 5), and when the value of ΔT is a positive value, that is, when the outdoor temperature is 3 ° C. or more higher than the indoor temperature (in FIG. 6). When it corresponds to the environmental state Z3), the outside air shutter 33 is opened (step # 9), and when the value of ΔT is a negative value, that is, when the outdoor temperature is 3 ° C. or more lower than the indoor temperature. When it corresponds to the environmental state Z4 in FIG. 6, the outside air shutter 33 is closed (step # 10).

  When the absolute value of the internal / external temperature difference ΔT is smaller than 3 [° C.] (when it corresponds to the environmental state Z5 in FIG. 6), the difference between the outdoor air and the indoor air is not significant in both humidity and temperature. Whether the air introduced into the bathroom BR is indoor air or outdoor air, it is considered that there is no significant difference in temperature and humidity with respect to the influence on the drying operation. In this embodiment, when the difference between outdoor air and indoor air is not significant for both humidity and temperature (when determined to be No in step # 4), the air conditioning state of the dressing room DR is not affected. In consideration of the above, the outdoor air shutter 33 is opened (step # 8), and outdoor air is mainly introduced.

  The table of FIG. 7 shows the open / closed states of the bathroom shutter 17, the dressing room shutter 18, the toilet shutter 19, and the outside air shutter 33 in the dry operation together with other types of operation such as heating operation described later. Show. The open / close state of the outdoor air shutter 33 marked with “* 1” and “* 2” in the figure is set by the open air shutter switching process executed when the driving operation is started. The open / close state * 1 of the outside air shutter 33 by the outside air shutter switching process in the drying operation is as described above. In addition, the outside air shutter switching process in the cool wind operation described later has a different content from the outside air shutter switching process in the drying operation described above.

Next, heating operation, ventilation operation, and cool wind operation will be described.
First, the heating operation will be described. In the heating operation, the control unit H closes all of the bathroom shutter 17, the dressing room shutter 18, the toilet shutter 19, and the outside air shutter 33 (see FIG. 7), stops the exhaust fan 13, and circulates the fan 8. The heating valve 9 is controlled to open and close so that the temperature in the bathroom BR rises, and the hot water as a heat medium is circulated and supplied to the heat exchanger 9 so that the heat heated by the heat exchanger 9 is circulated. Air is blown out from the outlet 5 into the bathroom BR. Then, based on the detection information of the bathroom thermistor 15, the operation of the circulation fan 8, the thermal valve 10, and the exhaust fan 13 is performed so that the temperature of the air in the bathroom BR sucked from the suction port 4 becomes the target temperature for heating operation. To control.

Specifically, when the heating operation switch 21 of the remote control operation unit R shown in FIG. 3 is turned ON, the heating (strong) lamp of the remote control operation unit R is lit and a timer setting display is displayed on the display unit 27. Then, the movable louver 11 of the outlet 5 moves to the set wind direction position, and the heating (strong) operation is started. When the heating operation switch 21 is turned ON during the heating (strong) operation, the control unit H switches from the heating (strong) operation to the heating (weak) operation. At this time, the timer time is set at the same setting time as the previous operation, but can be set to an appropriate time by the setting switch 24 instructing a decrease in the setting value and the setting switch 25 instructing an increase in the setting value. it can.
And the direction of the movable louver 11 is adjusted so that the air ventilated into the bathroom BR is in the blowing direction for heating that can be bathed directly by the bather.

Next, ventilation operation will be described. When the ventilation operation switch 23 of the remote control operation unit R is turned ON, the control unit H stops the operation of the circulation fan 8 and maintains the thermal valve 10 in the closed state, and the bathroom shutter 17 and the dressing room. The shutter 18 for the toilet and the shutter 19 for the toilet are opened, and the outside air shutter 33 is closed (see FIG. 7). The ventilation fan 13 is actuated, the movable louver 11 is actuated in a closed state, the air sucked from the bathroom BR is exhausted to the outside through the exhaust duct 12, and the air sucked from the dressing room DR and the toilet TR is also exhausted to the outdoors. I am doing so.
During the 24-hour ventilation operation when the 24-hour ventilation switch is turned on, the bathroom shutter 17 is closed (see FIG. 7), and the air sucked from the dressing room DR and the toilet TR is supplied to the exhaust fan 13. And operate to exhaust.

  Next, the cool wind operation will be described. When the cool air operation switch 22 of the remote control operation unit R is turned ON, the control unit H operates the circulation fan 8 while keeping the thermal valve 10 in the closed state, and opens the bathroom shutter 17. The dressing room shutter 18, the toilet and the shutter 19 are closed (see FIG. 7), the ventilation fan 13 is operated, and a part of the air sucked from the bathroom BR is exhausted to the outside through the exhaust duct 12. The air sucked from the BR is blown out into the bathroom BR through the ventilation path 7 without heating.

When the cool air operation is performed, if the outdoor air temperature is lower by 3 [° C.] or more than the indoor air temperature by the outdoor air shutter switching process for the cool air operation, the outdoor air shutter 33 is opened and blown out from the outlet 5 to the bathroom BR. Outdoor air is included in a part of the air that is generated.
And the direction of the movable louver 11 is adjusted so that the air ventilated into the bathroom BR is in the blowing direction for cool breeze that can be bathed directly by the bather.

  As shown in FIG. 3, the remote control operation unit R includes an outside air shutter changeover switch 41, an automatic / manual indicator 42 which is turned on when the open / close of the outside air shutter 33 is in an automatic control state and is turned off when in a manual control state.
