Description

Aspects of the invention generally relate to heating devices.

The temperature difference inside the house may put a strain on the body. For example, blood pressure may change abruptly as the temperature changes from a high temperature region to a low temperature region or from a low temperature region to a high temperature region. The effect of such temperature difference on the body is known as heat shock.

It is generally known that heat shock is likely to occur when taking a bath in winter. For example, the blood pressure is likely to fluctuate greatly when the user moves from the washroom to the bathroom or when he/she bathes in hot water.
On the other hand, heat shock can be suppressed by warming the bathroom and an adjacent room (for example, a washroom) adjacent to the bathroom. In order to suppress the heat shock, it is desirable to warm both the bathroom and the adjacent room and reduce the difference between the temperature of the bathroom and the temperature of the adjacent room. In order to heat both the bathroom and the adjacent room, there is a method of installing a heating device in each of the bathroom and the adjacent room. Alternatively, there is a method of blowing air to two rooms with one heating device.

If a heating device is installed in each of the bathroom and the adjacent room, costs such as equipment cost and construction cost will be higher than in the case where there is only one heating device. Therefore, it is desired to heat two rooms with one heating device. On the other hand, when heating two rooms with one heating device, the structure may be complicated and it may take time until the temperature rises. Further, since one heating device warms the two rooms, power consumption tends to increase.

The present invention has been made based on the recognition of such a problem, and an object of the present invention is to provide a heating device that can efficiently heat two rooms with one unit.

A first aspect of the present invention is a heating device that warms the air in a bathroom and the air in an adjacent room adjacent to the bathroom, which is provided in the adjacent room via a fan and an opening provided in the adjacent room. The air outlet includes a main body having an air inlet for sucking air, a heating unit for heating the air sucked from the air inlet, and an air outlet for blowing the air heated by the heating unit into the bathroom. The air blown from the air flows into the adjacent room through a communication port that connects the bathroom and the adjacent room, and a bathroom temperature sensor that measures the temperature in the bathroom and an adjoining room that measures the temperature in the adjacent room. A room temperature sensor and a control unit that controls the operations of the fan and the heating unit are further provided, and the control unit, based on the temperature in the bathroom and the temperature in the adjacent room, from the suction port to the A heating device for adjusting the amount of air sucked into a main body unit per unit time in the adjacent room .

According to this heating device, the heating device sucks the air in the adjacent room, heats the sucked air, and blows it out into the bathroom. Then, the blown air flows again into the adjacent room through the communication port. In this way, by circulating the heated air between the adjacent room and the bathroom by the heating device, it is possible to heat the two rooms with one device. Therefore, compared to the case where two devices are installed, it is possible to suppress an increase in the initial cost of installing the heating device and the number of construction steps. By circulating the heated air through the communication port, it is possible to efficiently heat the two chambers with a simple structure.
Further, the amount of air taken in by the heating device is changed depending on the temperature of the bathroom and the temperature of the adjacent room. Thereby, for example, when the temperature of the adjacent chamber is low, more air can be sucked in from the adjacent chamber and heated. Therefore, the temperatures of the two chambers can be efficiently raised in a short time. Further, the difference between the temperature of the bathroom and the temperature of the adjacent room can be reduced.

2nd invention is a 1st invention, The said control part WHEREIN: When the difference of the temperature in the said bathroom and the temperature of the said adjacent room becomes below a predetermined value, per unit time sucked by the said main-body part. The heating device is characterized by reducing the amount of air.

According to this heating device, when the temperature difference between the bathroom and the adjacent room becomes small, the electric power consumed for sucking air is suppressed. As a result, it is possible to reduce the difference between the temperature of the bathroom and the temperature of the adjacent room and suppress the heat shock while suppressing the power consumption.

In a third aspect based on the first or second aspect , at least one of a rate of change in temperature in the bathroom per unit time and a rate of change in temperature in the adjacent room per unit time is predetermined. The heating device further comprises a first notifying means for notifying when the value is lower than the value.

According to this heating device, when the door leading from the adjacent room to the outside such as the corridor is open, and the rate of temperature change (rate of increase) is low, the first notifying unit notifies. This allows the user to close the door or the like that was unintentionally opened. Therefore, it is possible to reliably heat the two chambers.

A fourth aspect of the present invention is a heating device that warms the air in a bathroom and the air in an adjacent room adjacent to the bathroom, the fan being in the adjacent room via an opening provided in the adjacent room. The air outlet includes a main body having an air inlet for sucking air, a heating unit for heating the air sucked from the air inlet, and an air outlet for blowing the air heated by the heating unit into the bathroom. The air blown from the air flows into the adjoining room through a communication port that connects the bathroom and the adjoining room, and operates the bath temperature sensor that measures the temperature in the bathroom, the fan, and the heating unit. Further comprising a control unit for controlling, the control unit warms the air in the bathroom until the temperature in the bathroom becomes a predetermined temperature or higher, and when the temperature in the bathroom becomes the predetermined temperature or higher, The heating device is characterized by increasing the amount of air in the adjacent chamber sucked from the suction port per unit time.

According to this heating device, the heating device sucks the air in the adjacent room, heats the sucked air, and blows it out into the bathroom. Then, the blown air flows again into the adjacent room through the communication port. In this way, by circulating the heated air between the adjacent room and the bathroom by the heating device, it is possible to heat the two rooms with one device. Therefore, compared to the case where two devices are installed, it is possible to suppress an increase in the initial cost of installing the heating device and the number of construction steps. By circulating the heated air through the communication port, it is possible to efficiently heat the two chambers with a simple structure.
Further , according to this heating device, the inside of the bathroom is first heated preferentially. After that, after the temperature in the bathroom rises above a predetermined temperature, the amount of air sucked from the adjacent room is increased to warm the adjacent room. At this time, in general, air easily flows from a higher temperature to a lower temperature, so that the air easily flows from the bathroom to the adjacent room through the communication port. Therefore, the air is easily circulated and the heat is easily diffused, so that the temperature in the adjacent chamber can be raised in a short time. This can reduce the temperature difference between the bathroom and the adjacent room.

In a fifth aspect based on the fourth aspect , the control section, when the temperature in the bathroom is equal to or higher than the predetermined temperature, the amount of electricity in the heating section and the air blown out from the outlet per unit time. The heating device is characterized by reducing at least one of the amounts of

According to this heating device, it is possible to reduce power consumption by reducing the amount of electricity supplied to the heating unit and the amount of air blown out per unit time.

A sixth aspect of the present invention is a heating device that warms the air in a bathroom and the air in an adjacent room adjacent to the bathroom, the fan being in the adjacent room through an opening provided in the adjacent room. The air outlet includes a main body having an air inlet for sucking air, a heating unit for heating the air sucked from the air inlet, and an air outlet for blowing the air heated by the heating unit into the bathroom. The air blown from the air flows into the adjacent room through a communication port that connects the bathroom and the adjacent room, and the main body section further includes a control section that controls operations of the fan and the heating section. The control unit increases the amount of air in the adjacent room sucked from the suction port per unit time after a lapse of a predetermined time from the start of heating operation.

According to this heating device, the heating device sucks the air in the adjacent room, heats the sucked air, and blows it out into the bathroom. Then, the blown air flows again into the adjacent room through the communication port. In this way, by circulating the heated air between the adjacent room and the bathroom by the heating device, it is possible to heat the two rooms with one device. Therefore, compared to the case where two devices are installed, it is possible to suppress an increase in the initial cost of installing the heating device and the number of construction steps. By circulating the heated air through the communication port, it is possible to efficiently heat the two chambers with a simple structure.
Further , according to this heating device, by setting a predetermined time period in advance, it is possible to warm the bathroom and the adjacent room based on the set time period. Thereby, heat shock can be suppressed.
That is, since the heated air is blown into the bathroom, the temperature of the bathroom easily rises as compared with the temperature of the adjacent room. Therefore, after a lapse of a predetermined time, the amount of air sucked from the adjacent chamber is increased and heating is performed. With this, the temperature difference between the bathroom and the adjacent room can be reduced with the predetermined time as a guide, and the heat shock can be suppressed.

In a seventh aspect based on the sixth aspect , the control section has a plurality of modes, and the plurality of modes include an output of the heating section and air blown out from the air outlet per unit time. The heating device is characterized in that they differ from each other in at least one of

For example, the sizes of the bathroom and the adjacent room differ depending on the site. According to this heating device, since the control unit has a plurality of modes, it is possible to execute a mode suitable for the target bathroom and the adjacent room among the plurality of modes. As a result, it is possible to prevent the temperature from becoming difficult to rise due to the sizes of the bathroom and the adjacent room.

An eighth aspect of the invention is characterized in that, in the sixth aspect of the invention, the control unit changes the amount of air sucked into the main body unit per unit time stepwise according to the elapsed time from the start of heating operation. It is a heating system that operates.

In this heating device, since the heated air is blown into the bathroom, the temperature of the bathroom easily rises as compared with the temperature of the adjacent room. Therefore, for example, the amount of air sucked from the adjacent chamber is increased stepwise according to the elapsed time, and heating is performed. As a result, the temperature difference between the bathroom and the adjacent room can be reduced, and heat shock can be suppressed.

A ninth aspect of the present invention is the heating device according to any one of the first to eighth aspects of the present invention, wherein the air outlet blows air toward the communication port.
According to this heating device, the heated air is easily blown into the adjacent chamber by being blown out toward the communication port. Therefore, the heated air is easily circulated between the bathroom and the adjacent room, and the two rooms can be heated more efficiently.
In a tenth aspect based on any one of the first to ninth aspects, a door opening/closing detection means and a second notification means are further provided, and the communication port connects the bathroom and the adjacent room.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same components are designated by the same reference numerals, and detailed description thereof will be appropriately omitted.
FIG. 1 is a perspective view showing a bathroom and an adjacent room in which a heating device according to an embodiment of the present invention is installed.
As shown in FIG. 1, the heating device 100 (heating system) according to the present embodiment is installed in the bathroom BR.
The bathroom BR is a space partitioned by the wash floor 13, the side wall 12, and the ceiling 11. In addition, a bathtub 14 is provided in the bathroom BR adjacent to the wash floor 13.

Next to the bathroom BR, an adjacent room NR adjacent to the bathroom BR is provided. The adjacent room NR is, for example, a washroom or a dressing room. The adjacent room NR is a space defined by the floor surface 15, the side wall 16, and the ceiling 17.

A wall 18 is provided between the bathroom BR and the adjacent room NR. The wall 18 is, for example, a part of the side wall 12 of the bathroom BR and a part of the side wall 16 of the adjacent room NR.

A communication port 25 that connects the bathroom BR and the adjacent room NR is provided between the bathroom BR and the adjacent room NR. The communication port 25 is, for example, a door 18d that is provided on the wall 18 and connects the adjacent room NR and the bathroom BR. The user can enter and exit between the bathroom BR and the adjacent room NR through the door 18d. Alternatively, the communication port 25 may be a louver (ventilation port) 30 provided in the door 18d. Generally, the gallery 30 is provided below the door 18d. The communication port 25 is not limited to the above, and may be any air passage (for example, an opening) that connects the bathroom BR and the adjacent room NR.

The side wall 16 of the adjacent room NR is provided with a door 16d leading to the outside such as a corridor. The side wall 12 of the bathroom BR may be appropriately provided with a window 12d or the like.
The main body 10 of the heating device 100 is installed, for example, on the ceiling 11 of such a bathroom BR. The heating device 100 is, for example, a built-in (ceiling embedded) type.

FIG. 2 is a block diagram showing a main configuration of a bathroom and an adjacent room provided with the heating device according to the embodiment. In FIG. 2, the air duct system and the electrical system are shown together.
FIG. 3 is a block diagram illustrating the heating device according to the embodiment.
As shown in FIG. 2, the main body 10 of the heating device 100 includes a fan 110 (blower), a suction port (first suction port 121 and second suction port 122), a control unit 130, a heating unit 140, and a blowout port 150. Have. An opening 20 is provided in the adjacent room NR. As shown in FIG. 1, the opening 20 is provided, for example, in the ceiling 17 of the adjacent room NR. The opening 20 is a suction means for the heating device 100 to suck in the air in the adjacent room NR, and may include, for example, a fan (ventilation fan, blower) provided in the opening of the ceiling.

A specific example of the heating device 100 will be described with reference to FIGS. 4(a) and 4(b).

FIG. 4A is a cross-sectional view showing the main body portion 10 of the heating device 100. As shown in FIG. 4A, the main body portion 10 of the heating device 100 has a case portion 10a (housing). The fan 110, the damper 103, and the heating unit 140 are provided inside the case unit 10a.

The first suction port 121, the second suction port 122, and the air outlet 150 are provided in the case portion 10a. For example, the first suction port 121, the second suction port 122, and the blowout port 150 are openings provided on the surface of the case portion 10a.

The first suction port 121 is connected to the opening 20 provided in the adjacent chamber NR, for example, via the duct D2. The first suction port 121 is an opening that communicates the inside of the adjacent chamber NR with the inside of the main body 10. As the fan 110 rotates, the first suction port 121 sucks air in the adjacent chamber NR through the opening 20.

The second suction port 122 is located on the lower surface of the case portion 10a. The lower surface of the case portion 10a is exposed inside the bathroom BR. The second suction port 122 is an opening that connects the inside of the bathroom BR and the inside of the main body unit 10. As the fan 110 rotates, the second suction port 122 sucks in the air in the bathroom BR.

The air sucked into the main body 10 from the first suction port 121 and the second suction port 122 flows to the damper 103. The direction of air flow is controlled by the position of the damper 103. When the damper 103 is located at the position shown in FIG. 4A, the sucked air is directed toward the heating section 140. The heating unit 140 is a heater that heats the sucked air. The air heated by the heating unit 140 heads for the air outlet 150.

The air outlet 150 is located on the lower surface of the case portion 10a. As a result, the sucked air is blown out into the bathroom BR from the air outlet 150. The air outlet 150 may be provided with a movable portion 151 (electric louver). The movable portion 151 can control the direction of the air blown out from the air outlet 150.

It should be noted that when the position of the damper 103 is changed, the sucked air can be made to flow not to the direction of the heating section 140 and the outlet 150 but to the opening 125 provided in the case section 10a. The opening 125 is connected to a duct D1 that leads to the outside. Accordingly, the heating device 100 can exhaust the air in the bathroom BR and the adjacent room NR to the outside to perform ventilation. When the heating device 100 performs the heating operation, the air passage to the duct D1 is closed, for example.

As shown in FIG. 4A, the case portion 10a includes a lower member 10b. At least a part of the lower member 10b is located below the fan 110. FIG. 4B is a perspective view showing the lower member 10b. FIG. 4B shows a state in which the lower member 10b is viewed from below (bathroom side). The lower member 10b has an opening 110e corresponding to the fan 110. For example, the air sucked from the first suction port 121 or the second suction port 122 flows toward the fan 110 via the opening 110e.

Further, the lower member 10b is provided with a first damper 201, a first motor 201b, a second damper 202, and a second motor 202b.
The first damper 201 is swingably supported by a first motor 201b. The direction of the first damper 201 can be changed by the first motor 201b. Thereby, the air passage between the first suction port 121 and the fan 110 can be opened or closed. That is, the first damper 201 can adjust the amount of air in the adjacent chamber NR sucked from the first suction port 121.

The second damper 202 is swingably supported by a second motor 202b. The direction of the second damper 202 can be changed by the second motor 202b. Thereby, the air passage between the second suction port 122 and the fan 110 can be opened or closed. That is, the amount of air in the bathroom BR sucked from the second suction port 122 can be adjusted by the second damper 202.

With the configuration described with reference to FIGS. 4A and 4B, the amount of air in the adjacent room NR sucked from the first suction port 121 and the amount of air in the bathroom BR sucked from the second suction port 122. Each of the amounts can be adjusted independently, for example. Further, in this example, the amount of air blown out from the air outlet 150 is substantially equal to the sum of the amount of air sucked in from the first suction port 121 and the amount of air sucked in from the second suction port 122. ..

Further, the control unit 130 (not shown in FIG. 4A) may be arranged inside the case unit 10a. The control unit 130 is a circuit such as a microcomputer. As shown in FIG. 3, the control unit 130 receives a signal from the remote controller 40 and signals from the door opening/closing detecting means 51 and the temperature detecting means 52 and 53 described later. Then, control unit 130 controls each element of heating device 100 based on the received signal. Specifically, the control unit 130 controls the operations of the fan 110, the heating unit 140, and the movable unit 151 (electric louver). Further, the control unit 130 can control the operations of the damper 103, the first damper 201 (first motor 201b), the second damper 202 (second motor 202b), and the notification means 61, 62 described later. it can. When a fan or the like is provided in the opening 20 of the adjacent room NR, the controller 130 can also control the operation of the fan. As described above, the control unit 130 controls the heating operation of the heating device 100.

The user can use the remote controller 40 to instruct setting and execution of each function of the heating device 100. For example, it is possible to start and stop the heating operation, the ventilation operation, the clothes drying operation, etc., and adjust the set temperature.

The air flow in the heating operation of the heating device 100 will be described with reference to FIG. 1 again.
For example, as shown by arrow A1, the air in the adjacent chamber NR is sucked into the main body 10 of the heating device 100 through the opening 20 and the first suction port 121. The sucked air is heated by the heating unit 140 and is blown into the bathroom BR as shown by an arrow A2. At least a part of the blown air flows into the adjacent chamber NR through the communication port 25 (the door 18d or the gallery 30) as shown by an arrow A3. Then, at least a part of the air that has flowed into the adjacent chamber NR is sucked again from the opening 20 as indicated by the arrow A4.

Further, for example, as shown by an arrow A5, the heating device 100 can suck the air in the bathroom BR through the second suction port 122. Then, the sucked air is heated by the heating unit 140 and blown into the bathroom BR as shown by an arrow A2.

Thus, the heating device 100 circulates the heated air between the adjacent room NR and the bathroom BR. As a result, it is possible to heat the two chambers with one device. Therefore, compared to the case where one heating device is installed in each room, it is possible to suppress an increase in the initial cost of installing the heating device and the number of construction steps.

When two rooms are warmed by one device, the time until the two rooms are warmed and power consumption may increase. Therefore, it is required to efficiently heat the two chambers with one device. However, when trying to heat efficiently, the structure of the device may be complicated. For example, if hot air is blown directly from the heating device to both the bathroom BR and the adjacent room NR, a plurality of outlets are required, and from the viewpoint of safety, the configuration of the hot air flow path is limited. There is. On the other hand, in the heating device 100 according to the embodiment, by circulating the heated air through the communication port 25, it is possible to efficiently heat the two chambers with a simple structure.

Further, during the heating operation, the air outlet 150 can blow air toward the communication port 25. For example, the movable portion 151 (electric louver) is controlled so that air is blown in the direction of the louver 30 or the direction of the open door 18d. This makes it easier for air to flow into the adjacent chamber NR. Therefore, the heated air easily circulates between the bathroom BR and the adjacent room NR, and the two rooms can be heated more efficiently.

Next, the operation of the heating device 100 will be further described.
Drawing 5 (a)-Drawing 5 (c) are top views showing a bathroom and an adjoining room in which a heating device concerning an embodiment is installed. The arrows in FIGS. 5A to 5C represent the flow of air.
FIG. 5A shows the two-room heating operation by the heating device 100. The two-room heating operation is similar to the operation of the heating device 100 described above with reference to FIG. That is, the main body 10 of the heating device 100 sucks the air in the bathroom BR and the air in the adjacent room NR, heats the sucked air, and then blows it out into the bathroom BR. As a result, the air in the bathroom BR and the air in the adjacent room NR are efficiently circulated while warming.

Such a two-room heating operation is performed, for example, before the user takes a bath. Thereby, when the user takes a bath, the inside of the bathroom and the adjacent room can be kept warm. Further, the difference between the temperature in the bathroom and the temperature in the adjacent room can be reduced. Thereby, heat shock can be suppressed.

As shown in FIG. 5B, the heating device 100 can also warm only the bathroom BR. For example, the operation of the first damper 201 described with reference to FIG. 4B stops the intake air from the adjacent chamber NR. Then, only the air in the bathroom BR is sucked into the main body 10 and heated by the heating unit 140. In this way, the heating operation may be performed by circulating the air only between the bathroom BR and the heating device 100.

The heating device 100 can also perform the ventilation operation as shown in FIG. The main body 10 of the heating device 100 sucks in at least one of the air in the bathroom BR and the air in the adjacent room NR, and discharges the sucked air to the outside.

As described above with reference to FIG. 3, the heating device 100 may include the temperature detecting means. The temperature detecting means is, for example, a bathroom temperature sensor 52 that measures the temperature in the bathroom BR and an adjacent room temperature sensor 53 that measures the temperature in the adjacent room NR.
The adjacent room temperature sensor 53 may be provided in the adjacent room NR, or may be provided in the opening 20 or the main body 10. For example, the temperature in the adjacent chamber NR may be the temperature of the air that has been sucked in through the opening 20 and has not reached the confluence 123 (see FIG. 2). The merging point 123 is a position where the air sucked from the first suction port 121 and the air sucked from the second suction port 122 merge. Similarly, bathroom temperature sensor 52 may be provided in bathroom BR or may be provided in main body 10. The temperature in the bathroom BR may be the temperature of the air sucked from the second suction port 122 and before reaching the confluence point 123.

By using such temperature detecting means, more efficient heating operation can be performed. For example, the control unit 130 adjusts the amount of air sucked into the main body unit 10 per unit time (cubic meter per second: m ³ /s) based on the temperature in the bathroom BR and the temperature in the adjacent room NR. To do.
The “amount of air sucked into the main body 10 per unit time” means the amount of air sucked from the first suction port 121 per unit time (m ³ /s) and the amount sucked from the second suction port 122. And the amount of air per unit time (m ³ /s). “Adjusting” the amount of air sucked into the main body unit 10 per unit time means the amount of air sucked from the first suction port 121 per unit time and the amount of air sucked from the second suction port 122 per unit time. Changing (increasing or decreasing) at least one of the amount of air. An example of such a heating operation will be described with reference to FIGS. 6, 7A, and 7B.

FIG. 6 is a flowchart showing the operation of the heating device according to the embodiment.
Drawing 7 (a) and Drawing 7 (b) are top views showing a bathroom in which a heating device concerning an embodiment was installed, and an adjoining room. Arrows in FIGS. 7A and 7B represent the flow of air. The relative size of the arrows in FIGS. 7A and 7B corresponds to the relative size of the flow rate. As illustrated in FIG. 6, the control unit 130 is in the standby state until the heating operation switch is turned on (step S101: No). When the heating operation switch is turned on based on a signal from the remote controller 40 (step S101: Yes), the control unit 130 draws in air from the bathroom BR and the adjacent room NR, heats the drawn air, and heats the bathroom BR. The fan 110, the heating unit 140, and the like are controlled so as to blow out (step S102).

In FIG. 6, the intake amount of the bathroom BR (the amount of air sucked from the second suction port 122 per unit time) is represented by Iy, and the intake amount of the adjacent room NR (suction from the first suction port 121 per unit time). The amount of air taken in) is represented by Ir. The initial intake amount of the bathroom BR is represented by Iys, and the initial intake amount of the adjacent room NR is represented by Irs. The temperature in the bathroom BR is represented by Ty, and the temperature in the adjacent room NR is represented by Tr.

When the absolute value of the difference between the temperature Tr in the adjacent room NR and the temperature Ty in the bathroom BR is larger than the predetermined value (temperature difference Ts) in step S103, the control unit 130 proceeds to step S104. When the temperature in the bathroom BR is higher than the temperature in the adjacent room NR in step S104, the control unit 130 executes step S105, and when the temperature in the bathroom BR is not higher than the temperature in the adjacent room NR, The control unit 130 executes step S106.

When the temperature of the bathroom BR is relatively high, the amount of intake air from the adjacent room NR (intake amount of the suction means) is increased (step S105). That is, as shown in FIG. 7A, the intake amount of the adjacent chamber NR is increased. As a result, the temperature of the adjacent room NR rises more easily than the temperature of the bathroom BR, and the difference between the temperature of the bathroom BR and the temperature of the adjacent room NR can be reduced. When the temperature of the adjacent room NR is relatively high, the control unit 130 increases the intake amount from the bathroom BR (the intake amount of the heating device) (step S106). That is, as shown in FIG. 7B, the amount of intake air in the bathroom BR is increased. As a result, the temperature of the bathroom BR is more likely to rise than the temperature of the adjacent room NR, and the difference between the temperature of the bathroom BR and the temperature of the adjacent room NR can be reduced. After steps S105 and S106, the control unit 130 performs the determination of step S103 again.

By changing the intake air amount according to the temperature as in steps S104 to S106, the air in the room having the lower temperature is preferentially warmed. Thereby, the temperatures of the two chambers can be efficiently raised in a short time. Further, the difference between the temperature of the bathroom BR and the temperature of the adjacent room NR can be reduced. In this example, the intake amount of the bathroom BR or the intake amount of the adjacent room NR is increased, but the embodiment is not limited to this. The adjustment of the intake air amount of the main body portion 10 includes changing the balance between the intake air amount from the bathroom BR and the intake air amount from the adjacent room NR. For example, one of the intake air amount from the bathroom BR and the intake air amount from the adjacent room NR may be reduced, or both may be increased or decreased.

In step S103, when the absolute value of the difference between the temperature Tr in the adjacent room NR and the temperature Ty in the bathroom BR is less than or equal to a predetermined value (temperature difference Ts), the control unit 130 is a unit sucked by the main body unit 10. The amount of air per time is reduced (step S107). That is, (Iy+Ir) is made smaller than (Iys+Irs). For example, Iy and Ir are made smaller than Iys and Irs, respectively. As a result, the power consumed to suck in air is suppressed. Thereafter, when the heating operation switch is turned off (step S108: Yes), the heating device 100 ends the process.

When the bathroom BR and the adjacent room NR are warmed and the temperature difference becomes small, even if the amount of air warmed by the heating device 100 is reduced thereafter, it is easy to maintain a high temperature and a small temperature difference. Therefore, by executing the above step S107, it is possible to reduce the difference between the temperature of the bathroom BR and the temperature of the adjacent room NR and suppress the heat shock while suppressing the power consumption. The predetermined value (temperature difference Ts) can be set to any value, but the smaller the value, the easier it is to suppress heat shock.

Further, as described above with reference to FIG. 3, the heating device 100 may include the notification unit 61 (first notification unit). The notification means 61 notifies the user when at least one of the rate of change Rb of the temperature in the bathroom BR per unit time and the rate of change Rn of the adjacent room NR per unit time is low. The notification means 61 may be a means using sound or a means using light (for example, a display provided on the remote controller 40).

For example, when the door 16d of the adjacent room NR is opened, the temperature does not rise even when the heating operation is performed, and the change rate Rn per unit time in the adjacent room NR may be low. The notification means 61 gives notification when the change rate Rn is lower than the predetermined value Cn. Further, for example, when the window 12d of the bathroom BR is open, the rate of change Rb per unit time in the bathroom BR may be low even if the heating operation is performed. The notification means 61 gives notification when the change rate Rb is lower than the predetermined value Cb. This can prompt the user to unintentionally close the door or the like that is left open. Therefore, the two chambers can be reliably heated.

The rate of change Rn and Rb can be measured by a test operation with the door and window closed, and the predetermined values Cn and Cb can be determined according to the values. Alternatively, the user may be allowed to appropriately select the predetermined values Cn and Cb.

Further, as described above with reference to FIG. 3, the heating device 100 may include the door opening/closing detection means 51 and the notification means 62 (second notification means). The door opening/closing detection means 51 is, for example, a sensor provided on the door 18d that connects the bathroom BR and the adjacent room NR. The door opening/closing detection means 51 can detect whether the door 18d is open or closed. When the door opening/closing detection means 51 detects that the door 18d is closed during the heating operation, the notification means 62 notifies the user. The notification means 62 may be a means by sound or a means by light.

During the heating operation as described with reference to FIG. 6, it is easier for air to circulate when the door 18d is open than when it is closed. Therefore, the door opening/closing detection means 51 and the notification means 62 can prompt the user to open the door during the heating operation. This makes it easier for the air in the bathroom BR to flow to the adjacent room NR, and shortens the time for warming the adjacent room NR.

Next, an example of the heating operation different from the example described with reference to FIG. 6 will be described with reference to FIG.
FIG. 8 is a flowchart showing the operation of the heating device according to the embodiment.
As shown in FIG. 8, when the heating operation switch is turned on (step S201: Yes), the control unit 130 controls the fan 110 and the heating unit 140 to blow warm air (heating air) (step S201). S202). In step S202, the intake air amount (Irs) from the adjacent chamber NR of the main body portion 10 is smaller than the intake air amount (Iys) from the bathroom BR of the main body portion 10. For example, the intake air amount Irs from the adjacent chamber NR is extremely small and may be substantially zero.

This step S202 is continued until the temperature in the bathroom BR becomes equal to or higher than a predetermined temperature (step S203: No). That is, in this example, the control unit 130 first executes control to preferentially warm the air in the bathroom BR until the temperature in the bathroom BR becomes equal to or higher than a predetermined temperature. The predetermined temperature may be an arbitrary temperature, and is based on, for example, a set temperature that the user can input to the remote controller 40. The predetermined temperature is preferably a temperature sufficient to suppress heat shock.

After that, when the temperature in the bathroom BR becomes equal to or higher than the predetermined temperature (step S203: Yes), the control unit 130 increases the intake amount from the adjacent room NR in step S204. That is, the intake air amount Ir of the adjacent chamber NR is made larger than the initial intake air amount (Irs in step S202).

As described above, the bathroom BR is preferentially warmed, and then step S204 is executed to warm the adjacent room NR. Here, in general, air easily flows from a higher temperature to a lower temperature. Therefore, when step S204 is executed, the air in the bathroom BR easily flows into the adjacent room NR through the communication port 25. Therefore, in step S204, the air easily circulates and the heat in the bathroom BR diffuses into the adjacent room NR, so that the temperature in the adjacent room NR can be raised in a short time. For example, a temperature difference is temporarily generated to promote the subsequent circulation of air. Thereby, the temperature difference between the bathroom BR and the adjacent room NR can be reduced.

Further, in step S204, the energization amount of the heating unit (heating unit 140) may be reduced. That is, the control unit 130 reduces the current (ampere) flowing through the heating unit 140. For example, the heating unit 140 is turned off. Thereby, power consumption can be suppressed. From the above, for example, after the bathroom BR is sufficiently warmed from the viewpoint of suppressing heat shock, the power consumption is reduced. As a result, it is possible to suppress power consumption while suppressing the occurrence of heat shock.

Further, in step S204, the amount of air blown out from the air outlet 150 per unit time may be reduced. That is, the sum of the intake air amount Ir from the adjacent room NR and the intake air amount Iy from the bathroom BR may be reduced. For example, when the heating unit 140 is a PTC (Positive Temperature Coefficient) heater, power consumption in the heating unit 140 can be suppressed by reducing the amount of air blown from the air outlet 150 per unit time. Then, when the heating operation switch is turned off (step S206), the heating device 100 ends the process.

Next, an example of a heating operation different from the examples described with reference to FIGS. 6 and 8 will be described with reference to FIGS. 9, 10(a) and 10(b). In this example, the temperature detecting means may not be provided.

FIG. 9 is a flowchart showing the operation of the heating device according to the embodiment.
Drawing 10 (a) and Drawing 10 (b) are top views showing a bathroom and an adjoining room in which a heating device concerning an embodiment is installed. The arrows in FIGS. 10A and 10B represent the flow of air. The relative size of the arrows in FIGS. 10A and 10B corresponds to the relative size of the flow rate.

As shown in FIG. 9, when the heating operation switch is turned on (step S301: Yes), the control unit 130 sucks air from the bathroom BR and the adjacent room NR, heats the sucked air, and blows it out to the bathroom BR. Thus, the fan 110, the heating unit 140, and the like are controlled (step S303).

In this example, the control unit 130 executes mode selection before executing step S303. For example, the control unit 130 can execute a plurality of modes, and one of the plurality of modes is selected in step S302. The respective modes are different from each other in at least one of the output (watt: W) of the heating unit 140 per unit time and the amount of air blown out from the air outlet 150 per unit time.

The size (size) of the bathroom BR and the size of the adjacent room NR differ depending on the site. Further, the layout of the bathroom BR, the layout of the adjacent room NR, the position of the main body portion 10, the position of the opening 20, and the like also differ from site to site. Therefore, a plurality of modes are prepared, and a mode having an output (output of the heating unit and air volume from the air outlet) suitable for the site is executed from among the plurality of modes. For example, when the room is large, the amount of air sucked from the room is increased or the output of the heating unit 140 is increased. When selecting the mode, for example, the user inputs a signal regarding the size of the room or the size of the output from the remote controller 40. The control unit 130 executes one of the modes based on the input signal. Accordingly, it is possible to prevent the temperature from becoming difficult to rise due to the sizes of the bathroom BR and the adjacent room NR.

When the first predetermined time has elapsed after starting the heating operation (step S304: Yes), the control unit 130 increases the intake amount from the adjacent chamber NR (the intake amount of the suction means) in step S305. FIG. 10A shows the initial blowing of air in step S303. FIG. 10B shows the state after step S305 is executed after the first predetermined time has elapsed from the start of the heating operation. The amount of intake air from the adjacent chamber NR in the state of FIG. 10B is larger than the amount of intake air from the adjacent chamber NR in the state of FIG. The amount of intake air from the bathroom BR in the state of FIG. 10(b) is smaller than the amount of intake air from the bathroom BR in the state of FIG. 10(a).

After that, when the second predetermined time has elapsed after executing step S305 (step S306: Yes), the control unit 130 further increases the amount of intake air from the adjacent chamber NR in step S307. After that, when the third predetermined time has elapsed after executing step S307 (step S308: Yes), the control unit 130 further increases the intake air amount from the adjacent chamber NR in step S309. Then, when the heating operation switch is turned off (step S310: Yes), the heating device 100 ends the process.

As described above, the control unit 130 adjusts the amount of air sucked into the main body unit 10 per unit time when a predetermined time has elapsed from the start of the heating operation. For example, the control unit 130 gradually increases the amount of air in the adjacent chamber NR sucked from the first suction port 121 per unit time. The predetermined time (first to third predetermined times) may be any time set by the user.

Since the heating device 100 blows heated air into the bathroom BR, the temperature of the bathroom BR easily rises as compared with the temperature of the adjacent room NR. Therefore, as described above, the amount of air sucked from the adjacent chamber NR is increased after a predetermined time elapses to heat. As a result, the temperature difference between the bathroom BR and the adjacent room NR can be reduced with the predetermined time as a guide, and the heat shock can be suppressed. Further, by setting the predetermined time, the temperature difference can be reduced at a timing necessary for the user, so that the two chambers can be efficiently heated without wasting power.

In addition, the intake air amount from the bathroom BR may be changed (increased or decreased) while the intake air amount from the adjacent room NR is changed (increased or decreased) according to the lapse of a predetermined time. The temperature difference can be reduced by changing the balance between the amount of intake air from the adjacent room NR and the amount of intake air from the bathroom BR after a predetermined time has elapsed.

While the user is taking a bath, the humidity in the bathroom BR is high. Therefore, it is desirable that the heating operation described with reference to FIGS. 6 to 10B be performed before the user takes a bath and not during the bath. This can prevent the humidity in the adjacent room NR from rising. The heating device 100 may detect the user's bathing with a humidity sensor or the like provided in the bathroom BR.
