Abstract

A heater is obtained which, when blowing warm air into an indoor space, suppresses the rise of the warm air even when the warm air is buoyant and allows the warm air to reach the floor surface efficiently.

When the heater 1 blows warm air from the first air duct 16, it is arranged to blow out the warm air with a temperature higher than that from the first air duct 16 in a vertical direction flowing higher than the warm air blown from the ceiling and the first air duct 16. The second air path 17 allows the warm air blown out from the second air path 17 to have a lower airflow, whereby the airflow blown out from the second air path 17 can suppress the rise of the buoyancy of the warm air blown out from the first air path 16. This allows warm air to reach the floor efficiently.

The frame 2 is formed with an inlet 10 facing the indoor space, a blowout outlet 11 facing the indoor space, and an air supply path 9 connecting the suction inlet 10 and the blowout outlet 11. Furthermore, the frame 2 forms an exhaust port 12 for exhausting air to the outdoors. The suction inlet 10 is covered with a decorative panel 8 . There is a gap between the frame 2 and the decorative panel 8 through which indoor air flows into the suction inlet. The blowout outlet 11 is connected to the hole formed in the frame 2 and communicates with the indoor space. The exhaust port 12 is a hole formed in the frame 2 and is connected to the outside of the heater 1 or a duct connected to the outside. Furthermore, the air supply duct 9 includes at least a common air duct 13, a circulation air duct 14, and a ventilation air duct 15. The common air duct 13 is an air duct connected from the suction inlet 10 to the bifurcation point of the circulation air duct 14 or the ventilation air duct 15 . The circulation air duct 14 and the ventilation air duct 15 are independent of each other. The circulating air duct 14 is connected to the common air duct 13 and blows the air sucked in from the indoor space by the blower 3 into the room through the blower outlet 11 . That is, the air path formed by the common air path 13 and the circulating air path 14 is the suction inlet 10 facing the indoor space, the blowout outlet 11 facing the indoor space, and the air path connecting the suction inlet 10 and the blowout outlet 11 .

In addition, the air blower 3 can suck the air in the indoor space from the suction port 10, and then exhaust the sucked air to the outdoors from the exhaust port 12 after passing through the common air duct 13 and the ventilation air duct 15.

The blowout guide 4 is provided in the blowout outlet 11 of the circulating air duct 14 which is an air supply path formed in the frame 2 . The blowout guide 4 is composed of a single member connected to a plurality of plates, and guides the airflow blown out from the blowout outlet 11 of the circulating air duct 14 so that the airflow flows in a direction that can be expressed by a vector, and the vector has a direction opposite to the lower left direction. , that is, the vertical component (direction indicated by arrow X) perpendicular to the vertical direction (direction indicated by arrow Z). The reason why the blower guide 4 is provided will be explained. In this embodiment, the heater 1 is installed in the bathroom, but in order to discharge the steam from the bathtub, the heater 1 is installed above the bathtub. Also, the bathtub is located on the right side of the bathroom, and the flushing area is located on the left side of the bathroom. That is, the flushing place is located in the lower left direction of the heater 1 . In this case, in order to keep the user located at the washing place warm, it is better for the heater 1 to blow air toward the washing place. In order to blow air toward the flushing area, the heater 1 according to Embodiment 1 has a blowout guide 4 that guides the airflow blown out from the blowout port 11 in a direction expressed by a vector having a direction toward the lower left, that is, The vertical component (the direction indicated by the arrow X) is the vertical component (the direction indicated by the arrow Z).

The air path dividing part 5 is provided in the circulating air path 14 of the air supply path 9 . The air path dividing part 5 is a plate material, and divides a part of the circulating air path 14 into the first air path 16 and the second air path 17, and divides the blowing outlet 11 into the first blowing outlet 16b and the second blowing outlet 17b. Specifically, the air path dividing portion 5 forms a first air path 16 on the right side of the circulation air path 14 together with the frame 2 , and forms a second air path 17 on the left side of the first air path 16 . The first air path 16 and the second air path 17 are independent linear air paths. That is, the first air path 16 and the second air path 17 have no arcs or right angles. The first air passage 16 includes: a first opening 16a, which inhales the air flow generated by the blower 3; and a first blowing outlet 16b, which is connected to the first opening 16a. The second air passage 17 includes: a second opening 17a, which inhales the air flow generated by the blower 3; and a second blowing outlet 17b, which is connected to the second opening 17a. That is, the air path dividing part 5 is provided in the air blowing path 9, divides the blowing outlet 11 into the first blowing port 16b and the second blowing port 17b, and divides a part of the air blowing path 9 to communicate with the first blowing port 16b. The first air passage 16 and the second air passage 17 connected with the second blowing outlet 17b. Among them, for example, as shown in FIG. 1 , the linear first air passage 16 and the second air passage 17 divided by the air passage dividing part 5 are approximately the same in length.

The heater 6 is provided in the first air duct 16 . The heater 6 is a heating means for heating the air in the first air passage 16 . The heater 6 has a plurality of heating elements arranged at predetermined intervals, a plurality of heat sinks are provided on the heating elements, and the air in the first air passage is heated by heat conduction. In addition, the heating means is not limited to this, as long as it can heat the air in the first air duct.

The baffle 7 (shown in FIG. 3 ) is a plate that switches these circulation air ducts 14 and ventilation air ducts 15 . The baffle 7 is equipped with a motor (not shown) and can be operated by a controller to switch the circulation air path 14 and the ventilation air path 15 .

The decorative panel 8 is installed on the ceiling of the indoor space in order to improve the decorative effect, and is exposed in the indoor space. FIG. 2 is a bottom view showing the decorative panel 8 of the heater 1 according to this embodiment. The decorative panel 8 includes a gap that does not block the suction inlet 10 and a decorative panel opening 8a. The decorative panel opening 8a is formed with a hole, which is communicated with the blowout outlet 11 and used to blow out airflow into the room.

The operation of the heater 1 constructed in this way will be explained. The heater 1 allows the user to select any one of heating, ventilation, and drying operation modes from a remote control or a controller on a control circuit board, and starts operation according to the selected operation mode.

FIG. 3 is a schematic diagram showing the air supply path 9 during the heating operation of the heater 1 according to the first embodiment. When the heating operation mode is selected, the baffle 7 is moved by a motor (not shown) to block the opening of the ventilation air passage 15 . Then, the controller drives the blower 3 to generate airflow. As shown by the arrow in FIG. 3 , the air flow generated by the blower 3 is sent to the circulating air path 14 , that is, the first air path 16 or the second air path 17 . Since the first air duct 16 is provided with the heater 6 as a heating means, the air passing through the first air duct 16 is heated by the heater 6 and becomes warm air. On the other hand, the air passing through the second air passage 17 will not be heated, but will still have the same temperature as the indoor air. The air flow blown out from the first air duct 16 and the second air duct 17 is sent to the room through the blowing guide part 4 . Details of the air flow blown out from the first air duct 16 and the second air duct 17 at this time will be described later. In this way, the heater 1 can send warm air to the room in the heating operation mode.

FIG. 4 is a schematic diagram showing the air supply path 9 in the ventilation operation mode of the heater 1 according to the first embodiment. When the ventilation operation mode is selected, the baffle 7 is moved by a motor (not shown) different from the motor that drives the fan 3a to block the opening of the circulation air path 14. Then, the controller drives the blower 3 to generate airflow. As shown by the arrow in FIG. 4 , the air flow generated by the blower 3 is sent to the ventilation air duct 15 , and then sent to the outside of the heater 1 through the exhaust port 12 . In this way, the heater 1 can discharge indoor air to the outside in the ventilation operation mode.

FIG. 5 is a schematic diagram showing the air supply path 9 in the drying operation mode of the heater 1 according to the first embodiment. When the drying operation mode is selected, the baffle 7 is moved by a motor (not shown) to open the openings of the ventilation air path 15 and the circulation air path 14 to communicate with the common air path 13 . Then, the controller drives the blower 3 to generate airflow. As shown by arrows in FIG. 5 , the air flow generated by the blower 3 is sent to either the circulation air duct 14 or the ventilation air duct 15 . In this way, in the dry operation mode, the heater 1 can discharge indoor moisture to the outside and send warm air, that is, dry air, to the room.

In addition, when switching between operating modes, the controller uses a motor (not shown) to move the baffle 7 to appropriately switch the circulation air path 14 and the ventilation air path 15 .

In addition, in each operation mode, the controller controls the heater 6 not to be energized when the circulating air duct 14 is not used or when there is no need to send warm air into the room.

Next, the air flow blown out from the circulating air duct 14, that is, the first air duct 16 and the second air duct 17 in the heating operation mode and the drying operation mode will be described. FIG. 6 is a schematic diagram showing the circulation air passage 14 of the first embodiment. As shown above, the air flow blown out from the first air duct 16 is heated by the heater 6, so its temperature is higher than the air existing in the room. The air flow blown out from the first air passage 16 is called warm air 18 . Since the air flow blown out from the second air duct 17 is not heated, it is still at the same temperature as the air existing in the room. The air flow blown out from the second air passage 17 is called non-warm air 19 . The non-heated 19 series airflow has a lower temperature than the heated 18 series. After the warm air 18 and the non-warm air 19 are blown out from the first air duct 16 and the second air duct 17 respectively, the blowing guide part 4 guides the air supply direction. In the example of FIG. 6 , the warm air 18 and the non-warm air 19 are guided toward the lower left direction. Here, because the second air path 17 that blows out the non-warm air 19 is located to the left of the first air path 16 that blows out the warm air 18, the non-warm air 19 guided by the blowing guide 4 is in the vertical direction. It is blown out in a manner that it flows upward than the warm air 18 . In addition, since the temperature of the warm air 18 is higher than that of the air existing in the room, buoyancy is generated, and the force acts in the upward direction, that is, upward. Here, the non-warm air 19 flows above the warm air 18 in the vertical direction. Since the non-warm air 19 has the same temperature as the air existing in the room, buoyancy is not generated and flows toward the floor surface as guided by the blowout guide 4 . Even if the warm air 18 moves upward due to buoyancy, it is induced by the air flow of the non-warm air 19 to suppress its rise and flows toward the air supply direction of the non-warm air 19, that is, the floor surface. In this way, the warm air 18 advances in the lower left direction and can reach the floor surface.

In addition, in the heater 1 of Embodiment 1, since the second blowout port 17b is provided between the first blowout port 16b and the decorative panel 8, it is possible to suppress the influence of the heat of the warm air on the decorative panel 8. . The effects caused by the heat of the warm air that the decorative panel 8 bears include thermal discoloration and thermal deformation.

First, the principles of thermal discoloration and thermal deformation of the decorative panel 8 will be explained. In conventional heaters, the warm air blown out from the blower outlet may increase the temperature around the blower outlet, and the components around the blower outlet may change color and deform due to heat. The main reason why warm air raises the temperature around the outlet is considered to be roughly two reasons. The first reason is that the temperature of the warm air is high. The second reason is that the warm wind speed is slow. Due to the characteristics of viscous fluid, the warm air blown out from the blower outlet becomes slower as it is closer to the wall of the air path. Therefore, especially due to the second reason, the warm air increases the temperature around the blower outlet.

According to this embodiment, since the second air outlet 17b is provided between the first air outlet 16b and the decorative panel 8, there are warm air 18 and non-warm air 19. The warm air 18 is drawn from the first air passage 16. The air flow blown out, the non-warm air 19 is the air flow blown out from the second air duct 17 to between the decorative panels 8 . Therefore, in the heater 1, the warm air 18 does not reach the decorative panel 8, and the warm air 18 is suppressed from heating the decorative panel 8. In addition, since the non-heated air 19 has the same temperature as indoor air, it does not heat the decorative panel 8 . Therefore, the heater 1 can suppress the influence of the heat of the warm air 18 that the decorative panel 8 bears.

As described above, the heater 1 of Embodiment 1 has the following structure, including a frame 2 forming an inlet 10 facing the indoor space, a blowout outlet 11 facing the indoor space, and connecting the suction inlet 10 and the blowout outlet 11 . The air supply duct 9 connected to the outlet 11; the air blower 3 is installed in the frame 2, sucking in the air in the indoor space from the suction inlet 10, causing the sucked air to pass through the air supply duct 9, resulting in blowing out from the blower outlet 11 to the indoor space Air flow; the air path dividing part 5 is provided in the air blowing path 9, dividing the blowing outlet 11 into the first blowing port 16b and the second blowing port 17b, and dividing a part of the air blowing path 9 into the first blowing port 16b The first air duct 16 that communicates with the second air duct 17 that communicates with the second blowout outlet 17b; and the heating means (heater 6) are arranged in the first air duct 16, and the first air duct 16 The air inside is heated; the air flow (warm air 18) blown out from the first blowing outlet 16b is blown out in a direction that can be represented by a vector. The vector has a component perpendicular to the vertical direction. From the second blowing outlet 17b The air flow blown out (non-warm air 19) has a lower temperature than the air flow blown out from the first blowing outlet 16b (non-warm air 19), and is higher in the vertical direction than the air flow blown from the first blowing outlet 16b. The air flow blown out by 16b is blown out in a way that it flows upward. In particular, the second air passage 17 blows out the airflow having a temperature higher than that blown out from the first blowout port 16b in a manner that it flows vertically higher than the airflow blown out from the first blowout port 16b (the warm air 18 corresponds). (Warm air 18 corresponds to) lower airflow (non-warm air 19 corresponds), so the airflow (non-warm air 19 corresponds) blown out from the second blowout outlet 17b can suppress the airflow (warm airflow corresponds to) blown out from the first blowout outlet 16b The wind 18 conforms to the rise caused by buoyancy, and the heater 1 in the first embodiment has the effect of allowing the warm air 18 to reach the floor surface efficiently.

In addition, the heater 1 of Embodiment 1 has the following structure as an additional structure. It is equipped with a blowout guide 4 which is provided at the blowout outlet 11 of the air blowing path 9 and guides the flow from the blower in a direction that can be represented by a vector. The vector of the air flow blown out from the blower outlet 11 (the warm air 18 and the non-warm air 19 correspond) has a component perpendicular to the vertical direction. With this additional configuration, the airflow blown out from the second blowout port 17b is blown out so as to flow vertically above the airflow blown out from the first blowout port 16b. Therefore, the non-warm air 19 is located in the warm air position. 18 above, the rise of the warm air 18 caused by the buoyancy can be suppressed, and the heater 1 of the first embodiment has the effect of allowing the warm air 18 to reach the floor surface efficiently.

In addition, the heater 1 in Embodiment 1 has the following structure as an additional structure. It is equipped with a decorative panel 8 exposed in the indoor space. The decorative panel 8 is formed with a hole communicating with the blower outlet 11. When the heater 1 is viewed from below in the vertical direction, the second air outlet 17b is provided between the first air outlet 16b and the decorative panel 8. With this additional structure, the heater 1 according to Embodiment 1 can suppress the heat received by the decorative panel 8 because the warm air 18 blown out from the first air duct 16 does not heat the decorative panel 8 . The effect of the influence caused by the heat of wind.

In addition, the heater 1 of Embodiment 1 has the following structure as an additional structure. The frame 2 and the air path dividing part 5 form the first air path 16 and the second air path so that each becomes a linear air path. Road 17. That is, the first air passage 16 and the second air passage 17 are formed such that the air passages do not have arcs or right angles. With this additional structure, the pressure loss in the first air duct 16 and the second air duct 17 is reduced, and each can maintain the wind speed of the blown air flow. The heater 1 of the first embodiment can efficiently supply air. effect.

As a first modification of Embodiment 1, the heater 1 may also be configured to include a heating means in the second air duct 17 . In this case, in the heating operation mode, the controller controls the heating means provided in the second air passage 17 not to operate. For example, when a second heater is installed in the second air duct 17 and the heating operation mode and the drying operation mode are selected, the controller does not energize the second heater, but only energizes the heater 6, and then , the blower 3 is driven in the same manner as in Embodiment 1 to generate air flow. In this way, when the heater 1 has an operation mode that only heats the room without sending warm air to the floor, it is possible to increase the amount of warm air supplied to the room. In the heating operation mode, it can be as follows As shown above, warm air is sent to the floor surface.

As a second modification of Embodiment 1, the heater 1 may be configured without the blowout guide 4 . In this case, the heater 1 is configured such that the second air outlet 17b is located above the first air outlet 16b. For example, the air circulation path 14 may be formed toward the lower left direction, and the second air outlet 17b may be located above the first air outlet 16b. By configuring in this manner, the second air path 17 blows out the airflow (warm air 18 ) with a temperature higher than that from the first blowout port 16 b in the vertical direction, flowing upward. The air flow blown out (corresponding to the warm air 18) is lower than the air flow (corresponding to the non-warm air 19), so the air flow (corresponding to the non-warm air 19) blown out from the second blowing outlet 17b can suppress the air flow blown out from the first blowing outlet 16b. Due to the rise of the air flow (the warm air 18 conforms to) caused by the buoyancy, the heater 1 can make the warm air 18 reach the floor surface efficiently.

As a third modification of Embodiment 1, the heater 1 may be installed not in the bathroom space but in an indoor space such as a living room space or an office space.

Embodiment 2 Next, reference is made to the heater 1 according to the second embodiment. In Embodiment 1, the heater 1 has a structure in which only one second air outlet 17b is formed on the left side of the first air outlet 16b. In Embodiment 2, the second blowout port 17b is formed at two positions across the first blowout port 16b. That is, in the heater 1 of Embodiment 2, two second blowing outlets 17b are formed, and one of the second blowing outlets 17b is formed on the left side of the first blowing outlet 16b, and the other second blowing outlet is formed on the left side of the first blowing outlet 16b. 17b is formed on the right side of the first blowing outlet 16b. In addition, the heater 1 of Embodiment 2 is the same as the heater 1 of Embodiment 1 except for the structure of the first air duct 16 and the second air duct 17. The same parts are described in Embodiment 2. Description is omitted.

FIG. 7 is a schematic diagram showing the heater 1 according to the second embodiment. In the heater 1 of Embodiment 2, the air path dividing part 5 forms the first air path 16 in the center of the circulating air path 14, and forms a total of two second air paths 17, one each in the left and right directions. That is, the second air passage 17 is formed at two positions on the left and right of the first air passage 16 and is located across the first air passage 16 in the left-right direction. The first air path 16 and the second air path 17 are independent linear air paths. That is, the first air path 16 and the second air path 17 have no arcs or right angles. The first air passage 16 includes: a first opening 16a, which inhales the air flow generated by the blower 3; and a first blowing outlet 16b, which is connected to the first opening 16a. The second air passages 17 respectively include: a second opening 17a, which inhales the air flow generated by the blower 3; and a second blowing outlet 17b, which is connected to the second opening 17a.

Next, the air flow blown out from the first air duct 16 and the second air duct 17 of the heater 1 according to the second embodiment will be described. FIG. 8 is a schematic diagram showing the circulation air path 14 of the heater 1 according to the second embodiment. FIG. 9 is a schematic diagram showing the air flow blown out by the heater 1 according to the second embodiment. As in Embodiment 1, when the air flow blown out from the first air passage 16, that is, the warm air 18, is blown out into the indoor space, buoyancy is generated and tends to go upward. Here, because the second blowout outlet 17b that blows out the non-warm air 19 is located to the left of the first blowout outlet 16b that blows out the warm air 18, the non-warm air 19 guided by the blowout guide 4 is in the vertical direction. It is blown out in a manner that it flows upward than the warm air 18 . Furthermore, the non-warm air 19 blown out from the second air outlet 17b located on the right side of the first air outlet 16b is blown out so as to flow below the warm air 18 in the vertical direction. That is, as shown in FIG. 9 , the warm air 18 is sandwiched between the non-warm air 19 in the up and down direction. Since the non-warm air 19 has the same temperature as the indoor air, buoyancy is not generated and flows toward the floor as guided by the blowout guide 4 . The non-warm air 19 flowing under the warm air 18 guides the warm air 18 toward the floor surface. Thereby, the flow of air toward the floor surface can be generated above and below the warm air 18. Even if the buoyancy is generated in the warm air 18, it will be induced by the air flow of the non-warm air 19 to suppress the rise and move to the direction of the non-warm air 19 supply. , that is, floor surface flow. In this way, the non-warm air 19 guides the warm air 18 to the floor surface in the up and down direction, so that the warm air 18 can reach the floor surface more effectively.

In addition, the first air duct 16 and the second air duct 17 configured in this manner can suppress the influence of the heat of the warm air received by the decorative panel 8 based on the same principle as in the first embodiment. In Embodiment 2, since there are two second air passages 17 between the first air passage 16 and the decorative panel 8, the influence of the heat of the warm air received by the decorative panel 8 can be further suppressed.

The second blower outlet 17b is formed in at least two positions of the frame 2, and the second blower outlet 17b is formed in one position (in The airflow blown out from the second blowout port 17b formed on the left side of the first blowout port 16b is blown out in a manner that it flows upward in the vertical direction than the airflow blown out from the first blowout port, and from The airflow blown out by the second blowout port formed at another position (corresponding to the second blowout port 17b formed to the right of the first blowout port 16b) is larger in the vertical direction than the airflow blown out from the first blowout port. The flow way further down is blown out. With this additional structure, the heater 1 according to Embodiment 2 can sandwich the warm air 18 blown out from the first air duct 16 from the up and down direction by the non-warm air 19 blown out from the second air duct 17 . Therefore, the flow of air toward the floor surface can be generated in the up-and-down direction of the warm air 18, thereby achieving the effect of allowing the warm air 18 to reach the floor surface more effectively.

Furthermore, the heater 1 of Embodiment 2 has the following structure as an additional structure. When the heater 1 is viewed from below in the vertical direction, the first outlet 16b is formed in one position. The second blower outlet 17b is sandwiched by the second blower outlet 17b formed at another position (the second blower outlet 17b is formed on the left and right of the first blower outlet 16b). With this additional structure, the non-warm air 19 blown out from the second air duct 17 can sandwich the warm air 18 blown out from the first air duct 16 from the up and down direction. Therefore, the heater 1 of Embodiment 2 generates a flow of air toward the floor surface in the up-and-down direction of the warm air 18, thereby allowing the warm air 18 to reach the floor surface more effectively.

In addition, the heater 1 of Embodiment 2 has the following structure as an additional structure. It is equipped with a decorative panel 8 exposed in the indoor space. The decorative panel 8 is formed with a hole communicating with the blower outlet 11. When the heater 1 is viewed from below in the vertical direction, the second air outlet 17b is provided between the first air outlet 16b and the decorative panel 8. With this additional structure, the heater 1 according to the second embodiment can suppress the heat received by the decorative panel 8 because the warm air 18 blown out from the first air duct 16 does not heat the decorative panel 8 . The effect of the influence caused by the heat of wind.

Moreover, the heater 1 of Embodiment 2 has the following structure as an additional structure. The frame 2 and the air path dividing part 5 form the first air path 16 and the second air path so that each becomes a linear air path. Road 17. That is, the first air passage 16 and the second air passage 17 are formed such that the air passages do not have arcs or right angles. With this additional structure, the pressure loss in the first air duct 16 and the second air duct 17 is reduced, and the wind speed of the blown air flow can be maintained respectively. The heater 1 of the second embodiment can efficiently supply air. effect.

In addition, the heater 1 of the second embodiment has the following structure as an additional structure. The blowout guide portion 4 has a point-symmetrical outline when the heater 1 is viewed from below in the vertical direction. When the blower outlet 11 is provided, the airflow is guided in the first direction. When the other direction is reversed from one direction with the symmetry point as the center, the airflow is directed in the first direction. The airflow is guided in a different second direction. With this additional structure, the blowout guide 4 is reversed around the symmetry point, that is, the blowout guide 4 is rotated around the Z-axis on a plane perpendicular to the Z-axis. The blower outlet 11 is arranged in a 180-degree manner, whereby the direction of the airflow can be changed. In the heater 1 of Embodiment 2, the blower guide 4 is point symmetrical because it is rectangular. The blower guide 4 may be inverted around the symmetry point and may be provided at the blower outlet 11 . In the heater 1 of Embodiment 2, the first direction is the lower left direction, and the second direction is the lower right direction. That is, by installing the blowout guide 4 shown in FIG. 8 so as to be rotated 180 degrees around the Z axis, it is possible to The airflow blown out from the blower outlet 11 is guided in the lower right direction. Furthermore, when the direction of the guided airflow is changed in this manner and the heater 1 is viewed from below in the vertical direction, the first blowout port 16b only needs to be formed between the second blowout port 17b formed at the same position. The position sandwiched by the second air outlet 17b formed at another position can be sandwiched by the non-warm air 19 blown out from the second air duct 17 from the up and down direction to the warm air 18 blown out from the first air duct 16, and This function allows the warm air 18 to reach the floor surface more effectively.

Moreover, the heater 1 of Embodiment 2 is similar to the first modification of Embodiment 1, and may also be configured to include a heating means in the second air duct 17 .

In addition, the heater 1 of Embodiment 2 is similar to the second modification of Embodiment 1, and may be configured without providing the blowout guide 4 . In this case, the heater 1 is configured such that at least one of the two second air outlets 17b is located above the first air outlet 16b. For example, the air circulation path 14 may be formed toward the lower left direction, with one second blowout port 17b located above the first blowout port 16b and the other second blowout port 17b located below the first blowout port 16b. By configuring in this manner, the second blowout port 17b on one side blows out air with a higher temperature than the airflow (warm air 18) blown out from the first blowout port 16b in the vertical direction. The air flow blown out from the outlet 16b (corresponding to the warm air 18) is lower than the air flow (corresponding to the non-warm air 19), so the air flow (non-warm air 19 conforming) blown out from the second blowing outlet 17b can suppress the air flow from the first blowing outlet 16b. The heater 1 can make the warm air 18 reach the floor surface efficiently by the rise of the blown air flow (the warm air 18 conforms to it) caused by the buoyancy.

In addition, the heater 1 of Embodiment 2 is the same as the third modification of Embodiment 1, and may be installed not in a bathroom space but in an indoor space such as a living room space or an office space.

In addition, as a modification of the heater 1 of Embodiment 2, the shape of the air path dividing portion 5 constituting the first air path 16 and the second air path 17 is such that the second air outlet 17b sandwiches the first air outlet 16b. , the number and shape of the blowing outlets are not particularly limited. 10 to 13 are schematic diagrams showing modifications of the air path dividing portion 5 when the heater 1 is viewed from below in the vertical direction. Each of the air path dividing portions 5 is configured such that the second blowout ports 17b are formed at two positions with the first blowout ports 16b interposed therebetween. As shown in FIG. 10 , the second blowout ports 17b may be provided at four corners of the first blowout port 16b. In addition, as shown in FIG. 11 , the shape of the blower outlet is not limited to a square shape, and may be a circle or a polygonal shape. As shown in FIG. 12 , the second blowout ports 17b may be provided at four corners of the first blowout port 16b. As shown in FIG. 13 , the second blower outlet 17b may be formed in two positions and connected in a direction parallel to the vertical direction, and may be one blower outlet surrounding the first blower outlet 16b. By configuring in this manner, the second blowout port 17b is formed in two positions across the first blowout port 16b.

In addition, this modification also exhibits the above-mentioned effects. In particular, the influence of the heat of the warm air that the decorative panel 8 bears can be suppressed. As long as there is a second blowout port 17b between the first blowout port 16b and the decorative panel 8, since the non-warm air 19 flows around the second blowout port 17b, it can at least be suppressed from being borne by the surrounding decorative panel 8. The influence caused by the heat of warm wind. For example, as shown in FIG. 11 , if the second blowout outlets 17b are provided at the four corners of the outer circumference of the first blowout outlet 16b, there will be no second blowout outlets 17b in a part of the outer circumference of the first blowout outlet 16b, and the decorative effect will be suppressed. The temperature of the panel 8 rises, so that the influence of the heat of the warm air that the decorative panel 8 bears can be suppressed.
