[0003] One example of this type of heater is a heater for preventing condensation. This heater effectively heats the air in the area surrounding the glass window by selecting its length to match the size of the glass window (window frame width). This means that the air heated by the heater circulates (rises) along the glass surface of the glass window through natural convection, preventing condensation on the glass window.

[0004] [Patent Document 1] Patent No. 4301752 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with conventional heater devices, although the heater length can be selected according to the window frame width, it is difficult to increase the distance that the heated air rises (radiates heat) when circulating it by natural convection. As a result, it is difficult for the heated air to reach a high position on the glass window, which creates the problem of insufficient effectiveness in preventing condensation on the glass window and reducing cold drafts.

[0006] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a heater appliance that can increase the upward heat dissipation (ascent) distance due to natural convection of heated air, and in particular, can effectively reduce condensation and cold drafts on glass windows. [Means for solving the problem]

[0007] In order to achieve the above object, the heating device of the present invention has a heating element respectively a lower heater section having a lower internal space formed by arranging a plurality of heater panels facing each other, the lower surface of the lower internal space being an air intake port and the upper surface of the lower internal space being a heat radiation port; respectively The heating element has an upper-level internal space formed by arranging a plurality of heater panels facing each other, the upper surface of the upper-level internal space being a heat dissipation port, and an upper-level heater section arranged above the lower-level heater section, the upper surface of the upper-level internal space being provided with an air intake port between the upper-level heater section and the lower-level heater section, and a pair of holding members that respectively hold both end portions of the upper-level heater section and the lower-level heater section.

[0008] In the heating appliance of the present invention, for example, natural convection due to the chimney effect is further promoted, so that heated air can reach high positions on glass windows that could not be reached before. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a heating appliance that can increase the upward heat dissipation (ascent) distance due to natural convection of heated air, and in particular, can effectively reduce condensation and cold drafts on glass windows.

[0011] Hereinafter, a heating appliance according to an embodiment of the present invention will be described with reference to the drawings.

[0012] [First embodiment] Fig. 1 is an external perspective view showing the overall structure of a heating fixture 1 according to a first embodiment of the present invention. Fig. 2(a) is a front view schematically showing the longitudinal direction of the heating fixture 1, Fig. 2(b) is a side view schematically showing the lateral direction of the heating fixture 1, Fig. 2(c) is a top view schematically showing the upper surface of the heating fixture 1, and Fig. 2(d) is a bottom view schematically showing the lower surface of the heating fixture 1.

[0013] In this first embodiment, a heater device (900 type) 1 having a longitudinal length of 900 mm or a heater device (1200 type) 1 having a longitudinal length of 1200 mm will be described as an example.

[0014] As shown in Figures 1 and 2(a) to (d), this heater fixture 1 includes a lower heater unit 3, an upper heater unit 5, a pair of holding members 7 that hold both ends of the lower heater unit 3 and the upper heater unit 5, and a power cord 9.

[0015] The power cord 9 has a power switch 9b that controls the flow of electricity to the heater (heating element) 41 described later and turns the heating device 1 on / off, and a power plug 9a that is connected to a commercial power outlet (not shown).

[0016] Furthermore, in the case of this heater fixture 1, the longitudinal length is set to 900 mm or 1200 mm, so one fixing member 8 corresponding to the holding member 7 is provided in the middle (intermediate) portion of the lower heater unit 3 and the upper heater unit 5. This fixing member 8 has a through hole according to the configuration of the lower heater unit 3 and the upper heater unit 5 (the arrangement pattern of the heater panels 31, 51). Similarly, the holding member 7 has an insertion groove on its inner surface according to the configuration of the lower heater unit 3 and the upper heater unit 5.

[0017] The lower heater section 3 has multiple heater panels 31 arranged opposite each other as lower panels, and the lower surface side of the lower internal space serves as an air intake port 2a as a first air intake port, and the upper surface side serves as a heat exhaust port (heat dissipation port).

[0018] The upper heater section 5 is arranged above the lower heater section 3, with multiple heater panels 51 arranged opposite each other as upper panels, and the upper surface of the upper internal space serving as a heat exhaust port (heat radiation port) 2b, and an air intake port 2c serving as a second air intake port between the upper heater section 5 and the lower heater section 3. The air intake ports 2a, 2c and the heat exhaust port 2b are all provided over the entire surface of the heater fixture 1 in the width direction (longitudinal direction) with approximately the same width.

[0019] Here, the lower heater section 3 includes three heater panels 31, for example, as shown in Fig. 3. The three heater panels 31 all have the same shape, for example, as shown in Fig. 5(a).

[0020] That is, the three heater panels 31 are made of a light metal member such as aluminum, have a hollow structure 32, and each heat dissipation surface is curved concavely in a cross section perpendicular to the longitudinal direction, thereby increasing the heat dissipation surface of the three heater panels 31 and increasing the effect of radiant heat.

[0021] As shown enlarged in Figure 5(b), grooves 33 are formed on the bottom and top surfaces of the three heater panels 31, for example, to engage with screws 7a, 8a when the panels are attached to the holding member 7 or the fixing member 8. The grooves 33 may have a V-shaped cross section or a U-shaped cross section. By providing the grooves 33 on the bottom and top surfaces of the three heater panels 31, they can be attached without any vertical restrictions.

[0022] In the lower heater section 3, the three heater panels 31 are supported by holding members 7 and fixing members 8, as shown in Figure 3, with a predetermined gap (air intake port 2a) between them and the floor surface, which is the installation surface such as under a window frame.

[0023] Of the three heater panels 31, the two outer panels are arranged so that, for example, to ensure stability during installation, the air intake port 2a on the lower surface is wider and the heat exhaust port on the upper surface is narrower, forming a figure-eight cross section that diverges toward the end. The inner panel is arranged so that it protrudes above the heat exhaust port formed by the two outer heater panels 31. This makes it possible to efficiently draw air from the air intake ports 2a and 2c by utilizing the temperature difference inside the upper heater unit 5, which is useful for utilizing the chimney effect.

[0024] On the other hand, the upper heater section 5 includes two heater panels 51, as shown in Fig. 3, for example. The two heater panels 51 have the same shape, as shown in Fig. 4, for example.

[0025] That is, the two heater panels 51 are made of a light metal member such as aluminum, have a hollow structure 52, and are curved so that at least the outer heat dissipation surface warps inward in a cross section perpendicular to the longitudinal direction, thereby increasing the heat dissipation surface of the two heater panels 51 and increasing the effect of radiant heat.

[0026] The two heater panels 51 are arranged opposite each other so that their cross sections form a figure-eight shape that diverges toward the end, and the maximum chimney effect is achieved by making the lower air intake 2c side wider and the upper heat exhaust 2b side narrower. In other words, the heat generated in the lower heater section 3 and the upper heater section 5 is condensed within the upper internal space of the upper heater section 5 and can be effectively released as natural convection from the heat exhaust 2b at the tip.

[0027] Furthermore, since the air intake port 2c is provided along the longitudinal direction between the lower heater unit 3 and the upper heater unit 5, the amount of air taken in through the air intake port 2c can be significantly increased, making it possible to efficiently generate natural convection. As a result, the distance over which heated air dissipates heat (ascents) upward due to natural convection can be significantly increased.

[0028] 3, for example, in the upper heater section 5, the distance A between the heater panels 51 is desirably about 3 to 10 mm (preferably about 6 mm). Also, the distance B between the heater panels 51 of the upper heater section 5, for example, the heater panel 31 on the inside of the lower heater section 3, is desirably about 2 to 10 mm. Furthermore, the distance C, which becomes the air intake 2c, for example, between the heater panel 31 on the outside of the lower heater section 3 and the heater panel 51 of the upper heater section 5, is desirably about 2 to 10 mm.

[0029] The holding member 7 and fixing member 8 are formed of, for example, thermosetting plastics. An LED (Light Emitting Diode) lamp 6 is provided on, for example, the top surface of the holding member 7, which lights up to indicate whether the heating device 1 is heating or off in response to the operation of the power switch 9b.

[0030] FIG. 6 is a circuit diagram showing an example of the configuration of the electric circuit section 40 of the heating appliance 1 of this embodiment.

[0031] As shown in Fig. 6, the electric circuit section 40 of the heating device 1 has five heaters 41 serving as heat sources, each corresponding to the heater panel 31 of the lower heater section 3 and the heater panel 51 of the upper heater section 5. The heaters 41 are constructed using a silicone rubber cord heater (silicon heater wire), a nichrome wire heater, a carbon fiber wire heater, or the like, and may be linear or planar, as long as they can be housed in a U-shape within the hollow sections 32, 52 of the heater panels 31, 51, for example.

[0032] That is, in the electric circuit section 40, one power wire of the power cord 9 connects in series three heaters 41 housed in the hollow portions 32 of each heater panel 31 of the lower heater section 3, and also connects in series two heaters 41 housed in the hollow portions 52 of each heater panel 51 of the upper heater section 5. In other words, the five heaters 41 housed in the hollow portions 32, 52 of the heater panels 31, 51, respectively, in a U-shaped state are connected to one power wire of the power cord 9 via connection points C1, C2 to form a closed circuit.

[0033] In addition, the other power line of the power cord 9 is connected to a connection point C1 between the heater 41 housed in the hollow portion 32 of the heater panel 31 of the lower heater section 3 and the heater 41 housed in the hollow portion 52 of the heater panel 51 of the upper heater section 5, via a current fuse Fi, a temperature fuse Fd, and a thermostat SS in that order.

[0034] Between one connection point C1 and the other connection point C2 connecting the heater 41 housed in the hollow portion 32 of the heater panel 31 of the lower heater section 3 and the heater 41 housed in the hollow portion 52 of the heater panel 51 of the upper heater section 5, a resistor R connected in series and a diode D facing in the opposite direction to the LED lamp 6 are connected in parallel.

[0035] In the electric circuit section 40 of this embodiment, when the temperature of the heater 41 exceeds a set temperature (for example, around 60°C), the thermostat SS is activated to control the temperature of the heater 41 to an optimum temperature. If, for example, the temperature of the heater 41 exceeds the set temperature despite this temperature control, the thermal fuse Fd is blown, cutting off the power supply to the heater 41.

[0036] By using, for example, a silicone rubber cord heater as the heater 41, it can be easily stored inside each hollow portion 32, 52 due to its flexibility, electrical insulation, heat resistance, etc., and a high level of safety can be ensured.

[0037] The heater 41 is not limited to being configured with a single heater wire, and may be configured such that, for example, each of the hollow portions 32, 52 houses a plurality of heater wires individually.

[0038] Furthermore, it is not necessary to accommodate the heaters 41 in all of the heater panels 31, 51, and it is also possible to omit accommodating the heaters 41 in some of the heater panels 31, 51, for example.

[0039] In addition, in this embodiment, an example is shown in which the temperature fuse Fd and thermostat SS are placed inside the inner heater panel 31 of the heater panel 31 of the lower heater section 3, but it is also possible to place them inside the outer heater panel 31 or the heater panel 51 of the upper heater section 5.

[0040] 7 shows the heat dissipation characteristics of the heater fixture 1 according to this embodiment in comparison with a conventional heater fixture. Here, a case where the conventional heater fixture is an anti-condensation heater 100 will be described. Note that the applied voltage (V) and power consumption (W) to the heater fixture 1 and the anti-condensation heater 100 are the same, and the obtained heat dissipation area Hd is compared.

[0041] As shown in the same figure (b), in the case of a conventional anti-condensation heater 100, for example, four heater panels 101 were arranged in a straight configuration parallel to the vertical direction perpendicular to the floor surface, so the heat dissipation area Hd (the amount of radiant heat WB, which is the amount of heat dissipated in the short direction, multiplied by the height of convection HB, which is the amount of heat dissipated upward) was extremely limited to only the peripheral area of ​​the anti-condensation heater 100.

[0042] In contrast, in the case of the heater fixture 1 of this embodiment, as is clear from Figure (a), the heat dissipation amount in the short direction (WA>WB) and the heat dissipation amount in the upward direction (HA>HB) can be significantly improved by accelerating natural convection due to the improved chimney effect, making it possible to increase the heat dissipation area Hd.

[0043] As described above, the heater fixture 1 according to the first embodiment can improve the upward heat dissipation (ascent) distance due to natural convection of heated air, and in particular can effectively reduce condensation and cold drafts on glass windows.

[0044] That is, the heater fixture 1 according to this embodiment is configured to include a lower heater unit 3 and an upper heater unit 5, with an air intake 2c provided between them, and the upper heater unit 5 being positioned above the lower heater unit 3. This significantly increases the amount of air drawn in through the air intake 2c, enabling natural convection to occur efficiently. This significantly increases the distance over which heated air dissipates heat (ascents) upward due to natural convection.

[0045] Furthermore, each heater panel 51 of the upper heater unit 5 is shaped like an eight, with the bottom air intake port 2c being wider and the top heat exhaust port 2b being narrower. This maximizes the chimney effect, allowing the heat generated in the lower heater unit 3 and the upper heater unit 5 to condense within the upper heater unit 5 and be efficiently released as natural convection from the heat exhaust port 2b at the tip. This allows heated air to reach high positions on the glass window that were previously out of reach, effectively reducing condensation and cold drafts on the glass window.

[0048] In the case of the heating fixture 1 according to the second embodiment configured as described above, substantially the same effects as those in the case of the heating fixture 1 according to the first embodiment can be obtained.
