If by towel etc. inaccessible the air outflow port or the radiating opening on framework top, then just become abnormal high temperature in the framework of electric panel heater, problems such as the distortion of framework or fault, fire might take place.Therefore, have in framework the temperature of installation and cross and rise anti-locking apparatus, when the air outflow port on framework top is inaccessible, cross the abnormal high temperature that rises in the anti-locking apparatus detection block body, stop safety device to the planar heat producing body energising by temperature.
In the electric panel heater of patent documentation 1, when using 2 frameworks, closure state compares when under the state that launches framework, using, and the temperature in the framework rises easily.It is strict that temperature conditions in framework when therefore, the air outflow port on framework top is by obturation also becomes.Therefore, be necessary to determine the structure of safety device, thereby when in framework, becoming abnormal high temperature, cross in the action that rises anti-locking apparatus in temperature and not produce delay, can safety, stop energising reliably to planar heat producing body.
Summary of the invention
The present invention solves described problem.Electric panel heater of the present invention has the structure that first panel unit and second panel unit are connected by linkage.The first and second panel unit U1 have the hollow that has radiating opening 4 in front framework 1, cover radiating opening 4 protector 3, from radiating opening 4 heat radiations be installed in the hot member 2 of screening at the rear of the planar heat producing body 5 of the inside of framework 1, the inside that is configured in framework 1 and planar heat producing body 5.Linkage 7 can be between the transversely arranged deployed condition of the radiating opening 4 of the radiating opening 4 of the closure state that the radiating opening 4 of the radiating opening 4 of the first panel unit U1 and the second panel unit U2 is faced mutually and the first panel unit U1 and the second panel unit U2, and the start point ground that changes between the framework 1 of the framework 1 of the first panel unit U1 and the second panel unit U2 connects the framework 1 of the first panel unit U1 and the framework 1 of the second panel unit U2.And, in the upper space in the framework 1 of the first panel unit U1, detect unusual temperature and rise just to stop to cross and rise an anti-locking apparatus 8 to first temperature of the power supply of planar heat producing body 5 if be provided with in position near the sidewall of the framework 1 that linkage 7 is set.In addition, in the upper space in the framework 1 of the second panel unit U2, detect unusual temperature and rise just to stop to cross and rise an anti-locking apparatus 8a to second temperature of the power supply of planar heat producing body 5 if be provided with in the position by sidewall of the opposite side of sidewall of the framework 1 that is positioned at and is provided with linkage 7.And first temperature is crossed and is risen anti-locking apparatus 8 under closure state, and not only the temperature in the framework 1 of the first panel unit U1 rises, and the framework 1 interior temperature that can also detect the second panel unit U2 rises.Second temperature is crossed and is risen anti-locking apparatus 8a under closure state, and the framework 1 interior temperature that not only detects the second panel unit U2 rises, and the framework 1 interior temperature that can also detect the first panel unit U1 rises.According to the present invention, when using under the closure state of the framework 1 of closed first and second panel unit U1 and U2, temperature is crossed and is risen anti-locking apparatus 8 and 8a and be subjected to respectively crossing the influence of heat of the radiating opening 4 of a side that rises anti-locking apparatus 8 and 8a from the temperature that do not have of the opposing party's framework 1.Especially under closure state, if cover the top of framework 1 with towel etc., the temperature in 2 frameworks 1 of facing mutually just rises together.As a result, 2 temperature are crossed and are risen anti-locking apparatus 8 and 8a and all be subjected to influence from the heat of relative framework 1, and the temperature that also detects in the opposing party's framework 1 rises, and can detect the abnormal high temperature of framework 1 reliably.
In addition, compare when using when under closure state, using the framework 1 of 2 panel unit U1 and U2 with under the state that launches framework 1, temperature in the framework 1 raises, when top is inaccessible, temperature in the framework 1 rises fast, and the temperature ascensional range after the energising of planar heat producing body 5 stops to increase, so be necessary that as far as possible temperature being crossed the operating temperature that rises anti-locking apparatus 8 and 8a sets lowly, even exist the temperature after the energising of planar heat producing body 5 stops to rise, also can be reliably stop in the temperature of safety.
In addition, can the lower margin 6 that framework 1 is left from ground be set respectively in the framework 1 of the first panel unit U1 and the framework 1 of the second panel unit U2.In addition, the diapire of framework 1 be provided with air from and ground between leaked-in air inflow entrance 9, air outflow port 10 can be set at the upper wall of framework 1.At this moment, in framework 1, form the air flow circuit 11 that is communicated with air inflow aperture 9 and air outflow port 10.And, it is desirable to first and second temperature and cross and rise anti-locking apparatus 8 and 8a and be configured in respectively in the air flow circuit 11 between the back wall that hides hot member 2 and framework 1.If like this, temperature is crossed and is risen anti-locking apparatus 8 and misoperation does not just take place 8a, and when the air outflow port of framework 1 10 was inaccessible, high temperature air was towards the rear side that hides hot member 2, so temperature is crossed and risen anti-locking apparatus 8 and the 8a temperature in can fast detecting framework 1 and rise.
In addition, under closure state, between the framework 1 of the framework 1 of the first panel unit U1 and the second panel unit U2, can certainly form the interval 12 that air flows.
In addition, if satisfy described condition, it just can be arbitrarily that first and second temperature are crossed the position that is provided with that rises anti-locking apparatus 8 and 8a.For example, first and second temperature are crossed and are risen anti-locking apparatus 8 and can fix at the opposite face relative with back wall that hides hot member 2 respectively with 8a.If this is provided with the position, just can improves temperature and cross the temperature measuring sensitivity that rises anti-locking apparatus 8 and 8a.At this moment, the end 2a that hides air outflow port 10 1 sides of hot member 2 tilts for along with near air outflow port 10, from the back wall of framework 1 away from.If like this, the hot top board 2a of screening by the high temperature air of the hot member 2 of screening of planar heat producing body 5 heating and the air flow circuit 11 between the radiating opening 4 top by hiding hot member 2, go to front one side of framework 1, rise to air outflow port 10 from the top of the end 2a that hides hot member 2.As a result, in the time of increasing air outflow port 10 and not stopping up and the temperature when stopping up cross the temperature difference that rises the temperature that anti-locking apparatus 8 and 8a detected, can prevent to detect misoperation and take place.
In addition, the sidewall in the relative side of sidewall that is positioned at the second panel unit U2 and framework 1 that linkage is set also can be provided with to the outstanding guidance panel 13 of the direction of leaving from framework 1.At this moment, the display part 13b that is provided for operating the operating portion 13a of running and shows operating condition in the front of guidance panel 13, and, at the internal configurations control substrate 14 of guidance panel 13.And, it is desirable to guidance panel 13 and have under closure state the size of exposing in the side of first panel unit.In addition, it is desirable to second temperature crosses and rises near the temperature that anti-locking apparatus 8a is set to also can detecting operation panel 13 and rise.If like this, just can be from the protection of the high temperature air in the framework 1 control substrate 14.

The specific embodiment
Below, with reference to accompanying drawing, describe an example of the electric panel heater of embodiments of the present invention (embodiment) in detail.Electric panel heater has the first panel unit U1 and the second panel unit U2.The first and second panel unit U1 and U2 have the hollow that has radiating opening 4 in front framework 1, cover radiating opening 4 protector 3, from radiating opening 4 heat radiations be installed in the planar heat producing body 5 of the inside of framework 1, in the inside of framework 1 and be configured in the hot member 2 of screening at the rear of planar heat producing body 5.Linkage 7, with the closure state of facing mutually at the radiating opening 4 of the radiating opening 4 of the first panel unit U1 and the second panel unit U2, and between the transversely arranged deployed condition of the radiating opening 4 of the first panel unit U1 and the radiating opening of the second panel unit U2 4, the mode of the start point between the framework 1 of the framework 1 of the first panel unit U1 and the second panel unit U2 be can change, the framework 1 of the first panel unit U1 and the framework 1 of the second panel unit U2 connected.At the diapire of framework 1, near sidewall, has a pair of lower margin 6.By this lower margin 6, framework 1 stands on the ground.
Diapire in the framework 1 of the framework 1 of the first panel unit U1 and the second panel unit U2 forms air inflow aperture 9, forms air outflow port 10 at the upper wall of framework 1.In addition, form the air flow circuit 11 that is communicated with air inflow aperture 9 and air outflow port 10 in the inside of framework 1.Hiding hot member 2 and planar heat producing body 5 is configured in the air flow circuit 11 of framework 1.If beginning is to the energising of planar heat producing body 5, just emit upward from the air outflow port 10 of the upper wall of framework 1 by the air in the air flow circuit 11 of planar heat producing body 5 heating.And the diapire and the air between the floor of framework 1 flow into air flow circuit 11 from air inflow aperture 9, along planar heat producing body 5, rise in air flow circuit 11.As a result, by the hot gas of emitting upward, in indoor generation free convection from air outflow port 10.
Under the state of framework 1 closure of the framework 1 of the first panel unit U1 and the second panel unit U2, the radiating opening 4 of 2 frameworks 1 is faced mutually.Under this state, between 2 frameworks 1, form interval 12.Front surface (front) in the framework 1 of a linkage 7 and an opposite side is provided with protuberance 15 respectively.In addition, rotate the installation site that axial region 7b and the mode of 12 positions of facing mutually, interval determine 2 installation component 7a of linkage 7 to become.As a result, be the center to rotate axial region 7b, 2 frameworks 1 are rotated, thus make radiating opening 4 mutually in the face of the time, 2 protuberances 15 contacts form at interval 12 between 2 frameworks 1.
Thereby when under the state that makes 2 frameworks 1 that the radiating opening 4 of 2 frameworks 1 is faced mutually, using electric panel heater, emit upward from the air outflow port 10 of the upper wall of framework 1 by the air in the air flow circuit 11 of the heat of planar heat producing body 5 heating, and emit to the top of framework 1 by the interval 12 interior air that the hot line from radiating opening 4 radiation (radiation) heats, so form high temperature air stream, can carry out heating based on free convection to the top of framework 1.
Sidewall in the framework 1 of the second panel unit U2 is wholely set guidance panel 13.The operating portion 13a that constitutes by running button and timer configuration switch etc. in the former configuration of guidance panel 13, the display part 13b that constitutes by front running lamp and timer lamp etc.According to signal, carry out the control substrate of the energising control of planar heat producing body 5 in the internal configurations of guidance panel 13 from operating portion 13a.If control substrate 14 just begins the energising of planar heat producing body 5 from operating portion 13a input running commencing signal.If the temperature of describing is later crossed the anti-locking apparatus 8 of liter and 8a becomes operating state, just stop based on energising that controlling substrate 14.
In the present embodiment, in the upper space in the framework 1 of the first panel unit U1, in the position of sidewall, detect unusual temperature and rise just to stop to cross and rise an anti-locking apparatus 8 to first temperature of the power supply of planar heat producing body (5,5) if be provided with near the framework 1 that is provided with linkage 7.In addition, in the upper space in the framework 1 of the second panel unit U2, detect unusual temperature and rise if be provided with, just stop to cross and rise an anti-locking apparatus 8a to second temperature of the power supply of planar heat producing body 5 in the position of the close sidewall of the opposite side of sidewall of the framework 1 that is positioned at and is provided with linkage 7.First temperature is crossed and is risen anti-locking apparatus (8) under closure state, and the framework 1 interior temperature that not only detects the first panel unit U1 rises, and the framework 1 interior temperature that can also detect the second panel unit U2 rises.In addition, second temperature is crossed and is risen anti-locking apparatus 8a under closure state, and the framework 1 interior temperature that not only detects the second panel unit U2 rises, and the framework 1 interior temperature that can also detect the first panel unit U1 rises.
First and second temperature of using in the present embodiment cross the anti-locking apparatus 8 of liter and 8a can reach operating temperature if measure temperature by have the temperature measuring function in inside, just the upper limit switch formation that 14 indication energisings stop to the control substrate.About having the upper limit switch of such function, be well-known, so omit detailed explanation.Become the above abnormal high temperature of operating temperature in the framework 1, if first and second temperature are crossed at least one side action that rises anti-locking apparatus 8 and 8a, control substrate 14 just receives that temperature crosses the signal of anti-locking apparatus 8 of liter and 8a, stops the energising of planar heat producing body 5.As a result, can prevent to produce the trouble that framework 1 is heated to abnormal high temperature.
The electric panel heater of present embodiment is and 1,2 framework 1 of framework of establishing the framework 1 of the first panel unit U1 and the second panel unit U2 is the structure that rotate at the center with the rotation axial region 7b of linkage 7.Therefore, for these 2 frameworks 1 do not become abnormal high temperature, determine that first and second temperature cross the installation site that rises anti-locking apparatus 8 and 8a.Promptly the temperature of a side framework 1 is crossed and is risen an anti-locking apparatus 8 and be configured near the sidewall of linkage 7 one sides, and the opposing party's temperature is crossed and risen anti-locking apparatus 8a and be configured near the sidewall with linkage 7 opposite sides.
When using under the state that launches 2 frameworks 1, first and second temperature are crossed the temperature that rises anti-locking apparatus 8 and 8a detection framework 1 separately.But first and second temperature are at this moment crossed the detection range that rises anti-locking apparatus 8 and 8a and are arrived respectively near the central authorities of framework 1.Therefore, when the part on the top of framework 1 is inaccessible, cross the detection range that rises anti-locking apparatus 8 and 8a but might depart from temperature., when using under the state that launches 2 frameworks 1, even the part on the top of framework 1 is inaccessible, hot gas is also emitted from its radiating opening 4 and air outflow port 10 on every side, so do not worry becoming abnormal high temperature in the framework 1.And the top of framework 1 is when striding in a wider range by obturation, and hot gas is difficult to emit, and becomes abnormal high temperature in the framework 1.At this moment, cross in the detection range that rises anti-locking apparatus 8 and 8a, can detect the abnormal high temperature in the framework 1, can reliably prevent the abnormal high temperature of framework 1 in temperature.
On the other hand, when under the state of the framework 1 of the framework 1 of the closed first panel unit U1 and the second panel unit U2, using, if the top of framework 1 is covered by article such as towels, the air outflow port 10 on framework 1 top and 12 top is just inaccessible at interval then.As a result, even the hot gas in the framework 1 is emitted from radiating opening 4, on 12 top at interval, flowing of hot gas also stops, so when even only the part on framework 1 top is inaccessible, framework 1 also becomes abnormal high temperature easily.
In the present embodiment, when under closure state, using electric panel heater, first temperature of the framework 1 of the first panel unit U1 cross the framework 1 that rises anti-locking apparatus 8 and the second panel unit U2 not have second temperature to cross the radiating opening 4 of a side that rises anti-locking apparatus 8a relative, second temperature of the framework 1 of the second panel unit U2 is crossed and is risen anti-locking apparatus 8a and face mutually with the radiating opening 4 that does not have first temperature to cross a side that rises anti-locking apparatus of the framework 1 of the first panel unit U1.Therefore, when for example near the top the sidewall of linkage 7 one sides was inaccessible, first temperature of the framework 1 by the first panel unit U1 was crossed and is risen an anti-locking apparatus 8, can detect the abnormal high temperature of 2 frameworks 1 of the first and second panel unit U1 and U2.And with the sidewall of linkage 7 opposite sides near top when inaccessible, second temperature of the framework 1 by the second panel unit U2 is crossed and is risen an anti-locking apparatus 8a, can detect the abnormal high temperature of 2 frameworks 1 of the first and second panel unit U1 and U2.Under the state of described closure, but first and second temperature cross the detection range that rises anti-locking apparatus 8 and 8a and can both utilize, so but that detection range becomes the transverse width of framework 1 is all.Therefore, when the part on the top of framework 1 was inaccessible, first and second temperature were crossed any one action that rises anti-locking apparatus 8 and 8a, can prevent that framework 1 is heated to abnormal high temperature.
According to present embodiment, the radiating opening 4 of 2 frameworks 1 can be towards direction arbitrarily in the scope of the start point that linkage 7 allows.Therefore, if the angle of 2 frameworks 1 of the first and second panel unit U1 and U2 is narrowed down, radiating opening 4 is relatively local, focuses on the place ahead of 2 frameworks 1 from the hot line of each radiating opening 4 radiation, although, also can improve heating effect so the radiation scope of hot line narrows down.By radiation scope, can improve and use randomness according to service condition change hot line.
In addition, when not using electric panel heater and when keeping,, just do not account for the place, easily keeping if become the state of closed first and second panel unit U1 and U2.
In the use of electric panel heater, if the top of framework 1 is covered and dead air flow export 10 by article such as towels, just become the hot gas of not discharging in the framework 1, become abnormal high temperature in the framework 1, if continue the energising of planar heat producing body 5 like this, just become the reason of the fault of the distortion of framework 1 or goods, might towel etc. article catch fire, produce great problems such as fire incident.
It is under the situation of deployed condition that Fig. 6 is illustrated in 2 frameworks 1 that make the first and second panel unit U1 and U2, an example of the state of the variations in temperature in the framework 1 when becoming closure state.If the top obturation of framework 1, the temperature in the framework 1 just begin to rise.Temperature in the framework 1 becomes first or second temperature and crosses the operating temperature that rises anti-locking apparatus 8 and 8a, rises anti-locking apparatus 8 and 8a action if first or second temperature is crossed, and just stops the energising of planar heat producing body 5.Becoming first or second temperature from the temperature in the framework 1 crosses the operating temperature that rises anti-locking apparatus 8 and 8a stops to the energising of planar heat producing body 5, temperature in the framework 1 also rises, the energising of planar heat producing body 5 stops the back temperature and also rises, so the operating temperature that the temperature in the framework 1 is crossed anti-locking apparatus 8 of liter and 8a than first and second temperature is higher.
In addition, compare when under the state that launches framework 1, using when under closure state, using 2 frameworks 1 of the first and second panel unit U1 and U2, temperature in the framework 1 is higher, when top is inaccessible, temperature in the framework 1 rises fast, temperature ascensional range after the energising of planar heat producing body 5 stops increases, so be necessary that as far as possible temperature being crossed the operating temperature that rises anti-locking apparatus 8 and 8a sets lowly, even exist the temperature after the energising of planar heat producing body 5 stops to rise, also can be reliably stop in the temperature of safety.In addition, cross the temperature ascensional range that rises in anti-locking apparatus 8 and the 8a action framework 1 since first and second temperature, bigger under closure state, the temperature in the framework 1 after the energising of planar heat producing body 5 stops is also higher.
Therefore, temperature rising part after the energising that is necessary to consider planar heat producing body 5 stops and set first and second temperature and cross the operating temperature that rises anti-locking apparatus 8 and 8a, in addition, temperature conditions when being necessary that 2 frameworks 1 of the first and second panel unit U1 and U2 are become closure state is set at benchmark.
On the other hand, be necessary first and second temperature are crossed and rise the position that anti-locking apparatus 8 and 8a are installed in the abnormal high temperature in can reliable detection framework 1.This installation site also might become the position of the influence that is subjected to hot gas easily under common user mode.Especially become closure state and when using electric panel heater in 2 frameworks 1 with the first and second panel unit U1 and U2, compare during with use under deployed condition, temperature in the framework 1 is higher, the difference that the temperature in the framework 1 of common user mode and first and second temperature are crossed the operating temperature that rises anti-locking apparatus 8 and 8a diminishes, and improves so temperature is crossed the possibility that rises anti-locking apparatus 8 and 8a generation misoperation.
In the embodiment of Fig. 2, the air that flows into air flow circuits 11 from the air inflow aperture 9 of framework 1 bottom is shunted forwards, backwards in the bottom that hides hot member 2, hide the air flow circuit 11 between hot member 2 and framework 1 back wall owing to hidden the heat that hot member 2 has blocked planar heat producing body 5, therefore flow through air than lower temperature.Therefore, first and second temperature are crossed rise anti-locking apparatus 8 and 8a is installed in the upper rear portion that hides hot member 2, be configured in the air flow circuit 11 that hides between hot member 2 and framework 1 back wall.
The end 2a that hides the top of hot member 2 becomes the hot top board of screening that forms in the upper end that hides hot member 2.Become the end 2a that hides hot top board, cross than first and second temperature rise anti-locking apparatus 8 and 8a the installation site more above, tilt to the front face side of framework 1.By the hot member 2 of screening of planar heat producing body 5 heating and the high temperature air of the air flow circuit 11 between the radiating opening 4, the end 2a of the hot top board of screening by becoming the top that hides hot member 2 rises to air outflow port 10 from the top of end 2a once towards front one side of framework 1.And the air of the low temperature that comes hiding air flow circuit 11 risings between the hot member 2 and framework 1 back side flows to air outflow port 10 from the upper wall that hides hot member 2a.Therefore, the high temperature air in the framework 1 is not crossed to temperature and is risen anti-locking apparatus 8 and 8a flows, can temperature cross rise anti-locking apparatus 8 and 8a around maintain low temperature.Therefore, when using 2 frameworks 1 of the first and second panel unit U1 and U2 under closure state, under common user mode, temperature is crossed the anti-locking apparatus 8 of liter and misoperation does not take place 8a.In addition, can cross the operating temperature that rises anti-locking apparatus 8 and 8a to temperature sets lowly.
In addition, if the top obturation of framework 1, just not from air outflow port 10 or at interval 12 top emit high temperature air, temperature in the framework 1 is risen, and the high temperature air that the top at top in framework 1 or interval 12 stops to flow is mobile to the upper rear portion that hides hot member 2 from air outflow port 10 and the gap that constitutes the end 2a that hides hot top board.As a result, the temperature that is installed in the upper rear portion that hides hot member 2 is crossed and is risen anti-locking apparatus 8 and 8a can move owing to high temperature air, thereby stops the energising of planar heat producing body 5, and can prevent the abnormal high temperature of framework 1 reliably.
In addition, control substrate 14 is thermo-labile, if temperature raises, just breaks down easily, so be necessary to protect it to avoid the influence of the high temperature air in the framework 1.In the present embodiment, as shown in Figure 1, dispose a pair of guidance panel 13, and form to the side of framework 1 outstanding at the sidewall with linkage 7 opposite sides of framework 1.Space 13c shown in Figure 1, be form in the inside of guidance panel 13, with framework 1 in distinguish the space of (district's picture) mutually, control substrate 14 is installed among the interior space 13c of guidance panel 13.
If become such structure, when the first and second panel unit U1 and U2 became closure state, guidance panel 13 was also outstanding to the side of the framework 1 of the first panel unit U1.Therefore, can not hide by the framework 1 latent guidance panel 13 that framework 1 at the second panel unit U2 is provided with of the first panel unit U1.Therefore, become possibility based on the running operation of operating portion 13a with based on the affirmation of the operating condition of display part 13b.In addition, do not go to the space 13c of guidance panel 13, can maintain low temperature to the control substrate of on the 13c of the space of guidance panel 13, installing 14 by the high temperature air in the framework 1 of planar heat producing body 5 heating.

Industrial utilizability
Electric panel heater of the present invention, and establish the framework 1 of 2 first and second panel unit U1 that have planar heat producing body 5 in inside and U2 and be connected 2 frameworks 1 with linkage 7, can with linkage 7 direction of center change radiating opening 4 courts, during the use of warming machine, launch 2 frameworks 1, radiating opening 4 becomes the state of opening, from and the radiating opening 4 radiation hot lines of 2 frameworks 1 of establishing, so can be to the scope heating in the place ahead of framework 1.And when using warming machine under closure state, the radiating opening 4 of 2 frameworks 1 is relative, and the heat of planar heat producing body 5 is emitted to the top of framework 1, can carry out the heating based on free convection.
In addition, in 2 frameworks 1 of the first and second panel unit U1 and U2, have first and second temperature that are used to detect the abnormal high temperature in the framework 1 and cross anti-locking apparatus 8 of liter and 8a, first temperature in the framework 1 of the first panel unit U1 is crossed and is risen an anti-locking apparatus 8 and be configured near the sidewall of linkage 7 one sides, and second temperature in the framework 1 of the second panel unit U2 is crossed and risen anti-locking apparatus 8a and be configured near the sidewall with linkage 7 opposite sides.Therefore, when using under launching the state of 2 frameworks 1, first and second temperature are crossed and are risen the abnormal high temperature that anti-locking apparatus 8 and 8a detect each framework 1.And when under closure state, using 2 frameworks 1, first and second temperature cross rise anti-locking apparatus 8 and 8a respectively with the opposing party's framework 1 not have temperature to cross the radiating opening 4 of a side that rises anti-locking apparatus 8 and 8a relative.Therefore, if the top obturation of framework 1, the temperature in relative 2 frameworks 1 rises, and temperature is crossed the anti-locking apparatus 8 of liter and risen with the temperature that 8a also can detect relative framework 1, detects the abnormal high temperature of framework 1 reliably.
