Fig. 2 is a bottom view showing the decorative panel 8 of the heater 1 of the present embodiment. The decorative panel 8 includes a gap that does not block the suction port 10 and a decorative panel opening 8a. The decorative panel opening 8a forms a hole, which communicates with the air outlet 11 and is used for blowing air into the room.

The operation of the heater 1 constructed in this way will be described. The heater 1 is selected by a user from a controller such as a remote controller or a control circuit board, and any one of heating, ventilation, and drying operation modes is started, and the operation is started according to the selected operation mode.

Fig. 3 is a schematic diagram showing the air supply passage 9 during the heating operation of the heater 1 according to the first embodiment. When the heating operation mode is selected, the baffle plate 7 is moved by a motor (not shown) to block the opening of the ventilation duct 15 . Then, the controller drives the blower 3 to generate air flow. As shown by the arrows in FIG. 3 , the airflow generated by the blower 3 is sent to the circulation air path 14 , that is, the first air path 16 or the second air path 17 . In the first air path 16, since there is the heater 6 as a heating means, the air passing through the first air path 16 is heated by the heater 6 to become warm air. On the other hand, the air passing through the second air passage 17 will not be heated, but still have the same temperature as the indoor air. The airflow blown from the first air passage 16 and the second air passage 17 is sent to the room through the blowing guide part 4 . The details of the airflow blown from the first air passage 16 and the second air passage 17 at this time will be described later. In this manner, 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 passage 9 in the ventilation operation mode of the heater 1 according to the first embodiment. When the ventilation operation mode is selected, the baffle plate 7 is moved by a motor (not shown) different from the motor driving the fan 3a to block the opening of the circulation air passage 14 . Then, the controller drives the blower 3 to generate air flow. As shown by the arrows in FIG. 4 , the airflow generated by the blower 3 is sent to the ventilation air passage 15 , and then sent to the outside of the heater 1 through the exhaust port 12 . In this way, the air heater 1 can discharge indoor air to the outside in the ventilation operation mode.

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

In addition, when switching the operation modes, the controller moves the damper 7 by means of a motor (not shown), so as to appropriately switch the circulation air passage 14 and the ventilation air passage 15 .

In addition, in each operation mode, the controller controls so that the heater 6 is not energized when the circulating air duct 14 is not used or when it is not necessary to send warm air into the room.

Next, the airflow blown from the circulating air passage 14, that is, the first air passage 16 and the second air passage 17 in the heating operation mode and the drying operation mode will be described. Fig. 6 is a schematic diagram showing the circulating air duct 14 of the first embodiment. As shown above, the airflow blown from the first air passage 16 is heated by the heater 6, so its temperature is higher than the air existing in the room. The airflow blown from the first air passage 16 is called warm air 18 . The airflow blown from the second air passage 17 is still at the same temperature as the air existing in the room because it is not heated. The airflow blown from the second air passage 17 is called non-warm air 19 . The non-warm air 19 is an air flow whose temperature is lower than the warm air 18 . After the warm air 18 and the non-warm air 19 are blown out from the first air path 16 and the second air path 17 respectively, the air blowing direction is guided by the blowing guide part 4 . In the example of FIG. 6 , the warm air 18 and the non-warm air 19 are guided in the lower left direction. Here, because the second air path 17 of blowing out the non-warm air 19 is positioned at the left side of the first air path 16 of the blowing warm air 18, the non-warm air 19 guided by the blowing guide 4 is in the vertical direction. It is blown out so as to flow above the warm air 18 . Also, the warm air 18 generates buoyancy because the temperature is higher than that of the air existing in the room, and the force acts in an upward direction, that is, upward. Here, the non-warm air 19 flows above the warm air 18 in the vertical direction. The non-warm air 19 is because of the same degree of temperature as the air existing in the room, so the buoyancy system does not produce, and goes to the floor surface as guided by the blowing guide part 4 . Even if the warm air 18 goes upwards due to buoyancy, it is also induced by the airflow of the non-warm air 19, and the rise is suppressed, and flows towards the air supply direction of the non-warm air 19, that is, the floor surface. By doing so, the warm air 18 is advanced in the lower left direction, and can reach the floor surface.

In addition, since the heater 1 of the first embodiment is provided with the second air outlet 17b between the first air outlet 16b and the decorative panel 8, the influence of the heat of the warm air received by the decorative panel 8 can be suppressed. . The series of 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 described. In conventional heaters, the temperature around the outlet may be increased by the warm air blown from the outlet, and the elements around the outlet may be discolored and deformed due to heat. The main reason why the 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 wind speed of the warm air is slow. Due to the characteristics of viscous fluid, the warm air blown from the air outlet is slower as it gets closer to the wall of the air path, so especially because of the second reason, the warm air increases the temperature around the air outlet.

If according to this embodiment, because the second air outlet 17b is set between the first air outlet 16b and the decorative panel 8, there are warm air 18 and non-warm air 19. The airflow blown out, the non-warm air 19 is the airflow blown between the decorative panels 8 from the second air path 17 . Therefore, in the heater 1, since the warm air 18 does not reach the decorative panel 8, heating of the decorative panel 8 by the warm air 18 is suppressed. Also, the non-warm air 19 does not heat the decorative panel 8 because it has the same temperature as the air in the room. Therefore, the heater 1 can suppress the influence of the heat of the warm air 18 received by the decorative panel 8 .

As shown above, the heater 1 of Embodiment 1 is constituted as follows, including: a frame body 2 forming a suction port 10 facing the indoor space, a blowing port 11 facing the indoor space, and connecting the suction port 10 and the blowing port. The air supply path 9 connected to the outlet 11; the blower 3 is arranged in the frame body 2, sucks the air in the indoor space from the suction port 10, and makes the inhaled air pass through the air supply path 9, and blows out from the air outlet 11 to the indoor space. Air flow; wind path dividing part 5 is arranged in the air supply path 9, and the air outlet 11 is divided into the first air outlet 16b and the second air outlet 17b, and a part of the air supply path 9 is divided into the first air outlet 16b and the first air outlet 16b. The first wind path 16 that communicates with the second air path 17 that communicates with the second outlet 17b; The air in the interior is heated; the airflow (warm air 18) blown out from the first outlet 16b is blown out in a direction that can be represented by a vector, and the vector has a component perpendicular to the vertical direction, and from the second outlet 17b The air-flow that blows out (non-warm air 19 meets) is the air-flow (non-warm air 19 meets) that temperature is lower than the air-flow that is blown out from the first outlet 16b, and in vertical direction than from the first outlet The airflow blown out by 16b is blown out in a manner of flowing upwards. In particular, the second air path 17 blows out a temperature higher than that of the airflow blown out from the first blowout port 16b by flowing in the vertical direction above the airflow (warm air 18) blown out from the first blowout port 16b. (The warm air 18 conforms to) lower airflow (the non-warm wind 19 conforms), so the air-flow blown from the second outlet 17b (the non-heated wind 19 conforms) can suppress the airflow blown from the first outlet 16b (warm Wind 18 accords with the rise caused by the buoyancy, and the heater 1 of Embodiment 1 plays the role of enabling warm air 18 to reach the floor surface with high efficiency.

Also, the air heater 1 of Embodiment 1 is an additional structure, and has the following structure. It is equipped with a blowing guide 4, which is provided at the blowing outlet 11 of the air supply passage 9, and guides the flow from The airflow (the warm air 18 and the non-warm air 19) blown out by the air outlet 11 has a component perpendicular to the vertical direction. With this additional configuration, since the airflow blown out from the second blowout port 17b is blown out in a vertical direction above the airflow blown out from the first blowout port 16b, the non-warm air 19 is located in the warm air position. The top of 18 can suppress the rise of the warm air 18 caused by the buoyancy, and the heater 1 of Embodiment 1 plays the role of enabling the warm air 18 to reach the floor surface with high efficiency.

Moreover, the heater 1 of Embodiment 1 is an additional structure, and has the following 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 air outlet 11. Looking at the heater 1 from below in the vertical direction, the second air outlet 17 b is provided between the first air outlet 16 b and the decorative panel 8 . With this additional structure, the heater 1 of Embodiment 1 can suppress the heat received by the decorative panel 8 because the warm air 18 blown from the first air passage 16 does not heat the decorative panel 8 . Efficacy of the influence caused by the heat of the wind.

Also, the heater 1 of Embodiment 1 is an additional structure, and has the following structure. The first air passage 16 and the second air passage 16 are formed by the frame body 2 and the air passage dividing part 5 to form a straight air passage respectively. Road 17. That is, the first air passage 16 and the second air passage 17 are in the air passage without arcs and right angles. With this additional structure, the pressure loss in the first air passage 16 and the second air passage 17 is reduced, and the wind speed of the airflow blown out can be maintained respectively, so that the heater 1 of the first embodiment can deliver air efficiently. effect.

As a first modified example of the first embodiment, the heater 1 may also be configured to provide heating means in the second air passage 17 as well. In this case, in the heating operation mode, the controller controls so that the heating means provided in the second air passage 17 does not operate. For example, in the case where the second heater is set in the second air passage 17, when the heating operation mode and the drying operation mode are selected, the controller will not energize the second heater, but only energize the heater 6, and then , the air blower 3 is driven in the same manner as in the first embodiment to generate air flow. In this way, the heater 1 can increase the amount of warm air sent to the room in the case of an operation mode in which it is only necessary to heat the room without sending warm air to the floor. In the heating operation mode, it can be used as As shown above, warm air is sent to the floor surface.

As a second modified example of the first embodiment, the air heater 1 may also be configured without the air outlet guide portion 4 . In this case, the heater 1 has a structure in which the second air outlet 17b is located above the first air outlet 16b. For example, what is necessary is just to form the circulation air path 14 toward the lower left direction, and to position the 2nd blower port 17b above the 1st blower port 16b. By being constituted in this way, the temperature of the second air path 17 is higher than that of the airflow (warm air 18) blown out from the first outlet 16b in the vertical direction than that from the first outlet 16b. The airflow blown out (in accordance with the warm air 18) is lower than the airflow (in accordance with the non-warm air 19), so the airflow (in accordance with the non-warm air 19) blown from the second outlet 17b can suppress the airflow from the first outlet 16b The rise caused by the buoyancy of the air flow (the warm air 18 conforms to), the heater 1 can make the warm air 18 reach the floor surface efficiently.

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

Implementation form 2 Next, the heater 1 of Embodiment 2 will be described with reference. In Embodiment 1, the heater 1 shows 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 via the first blowout port 16b. That is, in the heater 1 of Embodiment 2, two second outlets 17b are formed, and the second outlet 17b on one side is formed on the left side of the first outlet 16b, and the second outlet on the other side is formed on the left side of the first outlet 16b. 17b is a structure formed in the right side of the 1st outlet 16b. In addition, the heater 1 of Embodiment 2 is the same as the heater 1 of Embodiment 1 except for the configuration of the first air passage 16 and the second air passage 17, and the same parts are described in Embodiment 2. Description is omitted.

Fig. 7 is a schematic diagram showing a heater 1 according to the second embodiment. In the heater 1 according to Embodiment 2, the air passage division part 5 forms the first air passage 16 in the center of the circulating air passage 14, and forms two second air passages 17 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 arc or right angle in the air path. The first air passage 16 includes: a first opening 16a, which sucks the airflow generated by the blower 3; and a first air outlet 16b, which communicates with the first opening 16a. The second air passage 17 respectively includes: a second opening 17a for sucking in the airflow generated by the blower 3; and a second air outlet 17b for communicating with the second opening 17a.

Next, the air flow blown out from the first air passage 16 and the second air passage 17 of the heater 1 according to Embodiment 2 will be described. Fig. 8 is a schematic diagram showing the circulating air duct 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. Same as Embodiment 1, when the airflow blown from the first air passage 16, that is, the warm air 18 is blown to the indoor space, buoyancy is generated, and it wants to go upward. Here, because the second air outlet 17b that blows out the non-warm air 19 is positioned at the left side of the first air outlet 16b that blows out the warm air 18, the non-warm air 19 that is guided by the blowing guide portion 4 is in the vertical direction. It is blown out so as to flow above the warm air 18 . Moreover, 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 by the non-warm air 19 in the vertical direction. The non-warm air 19 is because it is the temperature of the same degree as the air in the room, so the buoyancy system will not produce, and it will go to the floor surface as guided by the blowing guide portion 4. The non-warm air 19 flowing below the warm air 18 guides the warm air 18 towards the direction of 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 is also induced by the airflow of the non-warm air 19, and the rise is suppressed, and the direction of the air supply of the non-warm air 19 is suppressed. , that is, floor surface flow. By doing so, the non-warm air 19 induces the warm air 18 to the floor surface in the vertical direction, so that the warm air 18 can reach the floor surface more efficiently.

Also, the first air passage 16 and the second air passage 17 constituted in this way are based on the same principle as that of the first embodiment, and can suppress the influence caused by the heat of the warm air received by the decorative panel 8 . 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.
