In the electric panel heater of patent document 1, when closure state uses 2 frameworks compared with when using under the state launching framework, the temperature in framework easily rises.Therefore, the air outflow port on framework top is also become strict by the temperature conditions in framework during obturation.Therefore, be necessary the structure determining safety device, thus when becoming abnormal high temperature in framework, cross in the action rising anti-locking apparatus in temperature and be not delayed, safely, reliably can stop the energising 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 surface Slab element is connected by linkage with the second panel unit.First and second panel unit U1 have the hollow above with radiating opening 4 framework 1, cover radiating opening 4 protector 3, from radiating opening 4 dispel the heat be arranged on the inside of framework 1 planar heat producing body 5, be configured in framework 1 inside and the hot component 2 of screening at the rear of planar heat producing body 5.Linkage 7 can between the facing closure state of the radiating opening 4 of the radiating opening 4 of first surface Slab element U1 and the second panel unit U2 and the radiating opening 4 of first surface Slab element U1 and the transversely arranged deployed condition of the radiating opening 4 of the second panel unit U2, and the expanded angle ground changed between the framework 1 of first surface Slab element U1 and the framework 1 of the second panel unit U2 connects the framework 1 of first surface Slab element U1 and the framework 1 of the second panel unit U2.And, in the upper space in the framework 1 of first surface Slab element U1, detect that abnormal temperature rising just stops the first temperature to the power supply of planar heat producing body 5 to cross the anti-locking apparatus 8 of liter if arranged in the close position arranging the sidewall of the framework 1 of linkage 7.In addition, in upper space in the framework 1 of the second panel unit U2, if detect that abnormal temperature rises just stop the second temperature to the power supply of planar heat producing body 5 to cross a liter anti-locking apparatus 8a with arranging by the position of sidewall of the sidewall opposite side of the framework 1 being provided with linkage 7 being positioned at.And the first temperature is crossed and risen anti-locking apparatus 8 in closed state, and the temperature in the framework 1 of not only first surface Slab element U1 rises, the temperature that can also detect in the framework 1 of the second panel unit U2 rises.Second temperature is crossed and is risen anti-locking apparatus 8a in closed state, and the temperature not only detected in the framework 1 of the second panel unit U2 rises, and the temperature that can also detect in the framework 1 of first surface Slab element 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 crosses the anti-locking apparatus 8 of liter and 8a is subject to crossing the impact of the heat of the radiating opening 4 of the side rising anti-locking apparatus 8 and 8a from the temperature that do not have of the opposing party's framework 1 respectively.Especially in closed state, if cover the top of framework 1 with towel etc., the temperature in 2 facing frameworks 1 just rises together.As a result, 2 temperature are crossed and are risen the impact that anti-locking apparatus 8 and 8a are subject to the heat from relative framework 1, and the temperature also detected in the opposing party's framework 1 rises, and reliably can detect the abnormal high temperature of framework 1.
In addition, when using the framework 1 of 2 panel unit U1 with U2 in closed state compared with when using under the state launching framework 1, temperature in framework 1 raises, when top is inaccessible, temperature in framework 1 rises fast, and the temperature ascensional range after the energising stopping of planar heat producing body 5 increases, so be necessary that as far as possible temperature being crossed the operating temperature rising anti-locking apparatus 8 and 8a sets low, even if the temperature after the energising that there is planar heat producing body 5 stops rises, also can reliably stop in the temperature of safety.
In addition, the lower margin 6 that framework 1 is left from ground can be set respectively in the framework 1 of the framework 1 of first surface Slab element U1 and the second panel unit U2.In addition, at the diapire of framework 1, air is set from leaked-in air inflow entrance 9 between ground, 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 being communicated with air inflow aperture 9 and air outflow port 10.And, it is desirable to the 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 that hides between hot component 2 and the back wall of framework 1.If like this, temperature is crossed and is risen anti-locking apparatus 8 and 8a and just misoperation does not occur, and when the air outflow port 10 of framework 1 is inaccessible, high temperature air is towards the rear side hiding hot component 2, so temperature is crossed and risen the temperature that anti-locking apparatus 8 and 8a can detect in framework 1 fast and rise.
In addition, in closed state, the interval 12 of air flowing can certainly be formed between the framework 1 and the framework 1 of the second panel unit U2 of first surface Slab element U1.
In addition, if meet described condition, it can be just arbitrary that the first and second temperature cross the setting position rising anti-locking apparatus 8 and 8a.Such as, the first and second temperature are crossed and are risen anti-locking apparatus 8 and 8a and can fix at the opposite face relative with back wall hiding hot component 2 respectively.If this setting position, just can improve temperature and cross the temperature measuring sensitivity rising anti-locking apparatus 8 and 8a.At this moment, the end 2a inclination hiding air outflow port 10 side of hot component 2 is along with close to air outflow port 10, away from the back wall of framework 1.If like this, the high temperature air of the air flow circuit 11 between the hot component of the screening of being heated by planar heat producing body 52 and radiating opening 4 is by hiding the hot top board 2a of screening on the top of hot component 2, go to side before framework 1, rise to air outflow port 10 from the top of the end 2a hiding hot component 2.As a result, to increase when air outflow port 10 does not block and blocking time temperature cross the temperature difference rising the temperature that anti-locking apparatus 8 and 8a detect, can prevent detecting misoperation and occur.

Detailed description of the invention
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 first surface Slab element U1 and the second panel unit U2.First and second panel unit U1 and U2 have the hollow above with radiating opening 4 framework 1, cover radiating opening 4 protector 3, to be arranged on dispelling the heat from radiating opening 4 inside of framework 1 planar heat producing body 5, be configured in the hot component 2 of screening at the rear of planar heat producing body 5 in the inside of framework 1.Linkage 7, with at the radiating opening 4 of first surface Slab element U1 and the facing closure state of the radiating opening 4 of the second panel unit U2, and between the radiating opening 4 of first surface Slab element U1 and the transversely arranged deployed condition of the radiating opening 4 of the second panel unit U2, the mode of the expanded angle between the framework 1 of first surface Slab element U1 and the framework 1 of the second panel unit U2 can be changed, connect the framework 1 of first surface Slab element U1 and the framework 1 of the second panel unit U2.At the diapire of framework 1, at adjacent sidewalls, there is a pair lower margin 6.By this lower margin 6, framework 1 is vertical on the ground.
Linkage 7 is made up of 2 installation component 7a on the sidewall of the framework 1 with the framework 1 of the second panel unit U2 that are fixed on first surface Slab element U1 and the turning cylinder portion 7b that is connected 2 installation component 7a rotationally.
Linkage 7, according to centered by turning cylinder portion 7b, the framework 1 of the framework 1 of first surface Slab element U1 and the second panel unit U2 mode of rotating, connect 2 frameworks 1.And, the closure state facing from the radiating opening 4 of the framework 1 of the radiating opening 4 and the second panel unit U2 that make the framework 1 of first surface Slab element U1 makes radiating opening 4 towards the state in front to expansion 2 frameworks 1, and linkage 7 can change expanded angle.As a result, in the electric panel heater of present embodiment, in the radiation scope of horizontal expansion hot line, can heat to the broad scope in the front of 2 frameworks 1.
Form air inflow aperture 9 at the diapire of the framework 1 of first surface Slab element U1 and the framework 1 of the second panel unit U2, form air outflow port 10 at the upper wall of framework 1.In addition, the air flow circuit 11 being communicated with air inflow aperture 9 and air outflow port 10 is formed in the inside of framework 1.Hide hot component 2 and planar heat producing body 5 is configured in the air flow circuit 11 of framework 1.If start the energising to planar heat producing body 5, the air in the air flow circuit 11 heated by planar heat producing body 5 is just released upward from the air outflow port 10 of the upper wall of framework 1.And the air between the diapire of framework 1 and floor 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 releasing upward from air outflow port 10, in indoor generation free convection.
Under the state that the framework 1 of first surface Slab element U1 and the framework 1 of the second panel unit U2 close, the radiating opening 4 of 2 frameworks 1 is facing.In this condition, between 2 frameworks 1, interval 12 is formed.At the front surface (above) of the framework 1 of linkage 7 and opposite side, protuberance 15 is set respectively.In addition, the installation site of 2 installation component 7a of linkage 7 is determined in the mode becoming the facing position of turning cylinder portion 7b and interval 12.As a result, centered by turning cylinder portion 7b, 2 frameworks 1 are rotated, thus when making radiating opening 4 facing, 2 protuberances 15 contact, and form interval 12 between 2 frameworks 1.
When being closure state making 2 frameworks 1 thus using electric panel heater under making the facing state of the radiating opening 4 of 2 frameworks 1, air in the air flow circuit 11 heated by the heat of planar heat producing body 5 is released upward from the air outflow port 10 of the upper wall of framework 1, and the air in the interval 12 of being heated by the hot line from radiating opening 4 radiation (radiation) is released to the top of framework 1, so form the high temperature air stream to the top of framework 1, the heating based on free convection can be carried out.
At the sidewall of the framework 1 of the second panel unit U2, be wholely set guidance panel 13.The operating portion 13a be made up of operate button and timer configuration switch etc. in the former configuration of guidance panel 13, the display part 13b be made up of front running lamp and timer lamp etc.In the configuration of the inside of guidance panel 13 according to the signal from operating portion 13a, the control substrate that the energising carrying out planar heat producing body 5 controls.If control substrate 14 to input running commencing signal from operating portion 13a, just start the energising of planar heat producing body 5.If the temperature described below crosses the anti-locking apparatus 8 of liter and 8a becomes operating state, just stop based on the energising controlling substrate 14.
In the present embodiment, in upper space in the framework 1 of first surface Slab element U1, in the close position being provided with the sidewall of the framework 1 of linkage 7, detect that abnormal temperature rising just stops the first temperature to the power supply of planar heat producing body (5,5) to cross and rises anti-locking apparatus 8 if be provided with.In addition, in upper space in the framework 1 of the second panel unit U2, if detect that abnormal temperature rises being positioned to arrange with the position of the close sidewall of the sidewall opposite side of the framework 1 being provided with linkage 7, just stop the second temperature to the power supply of planar heat producing body 5 to cross and rise an anti-locking apparatus 8a.First temperature is crossed and is risen anti-locking apparatus (8) in closed state, and the temperature not only detected in the framework 1 of first surface Slab element U1 rises, and the temperature that can also detect in the framework 1 of the second panel unit U2 rises.In addition, the second temperature is crossed and is risen anti-locking apparatus 8a in closed state, and the temperature not only detected in the framework 1 of the second panel unit U2 rises, and the temperature that can also detect in the framework 1 of first surface Slab element U1 rises.
The first and second temperature used in present embodiment cross the anti-locking apparatus 8 of liter and 8a can have temperature measuring function by inside, if measure temperature to reach operating temperature, just indicate the upper limit switch of energising stopping to form to controlling substrate 14.About the upper limit switch with such function, be well-known, so omit detailed description.Become the abnormal high temperature of more than operating temperature in framework 1, if the first and second temperature cross at least one party's action rising anti-locking apparatus 8 and 8a, control substrate 14 and just receive the signal that temperature crosses the anti-locking apparatus 8 of liter and 8a, stop the energising of planar heat producing body 5.As a result, trouble framework 1 being heated to abnormal high temperature can be prevented.
The electric panel heater of present embodiment is and establishes the structure that framework 1,2 frameworks 1 of the framework 1 of first surface Slab element U1 and the second panel unit U2 are rotated centered by the turning cylinder portion 7b of linkage 7.Therefore, in order to these 2 frameworks 1 do not become abnormal high temperature, determine that the first and second temperature cross the installation site rising anti-locking apparatus 8 and 8a.Namely the temperature of the framework 1 of a side is crossed and is risen the adjacent sidewalls that anti-locking apparatus 8 is configured in linkage 7 side, and the temperature of the opposing party is crossed the anti-locking apparatus 8a of liter and is configured in the adjacent sidewalls with linkage 7 opposite side.
When using under the state of expansion 2 frameworks 1, the first and second temperature are crossed and are risen the temperature that anti-locking apparatus 8 and 8a detect respective framework 1.At this moment the first and second temperature are crossed and are risen can detection range arriving respectively near the central authorities of framework 1 of anti-locking apparatus 8 and 8a.Therefore, when the part on the top of framework 1 is inaccessible, likely depart from temperature cross rise anti-locking apparatus 8 and 8a can detection range., when using under the state of expansion 2 frameworks 1, even if the part on the top of framework 1 is inaccessible, hot gas is also released from the radiating opening 4 around it and air outflow port 10, so do not worry becoming abnormal high temperature in framework 1.And the top of framework 1 is across during in a wider range by obturation, hot gas is difficult to release, and becomes abnormal high temperature in framework 1.At this moment, cross in the detection range rising anti-locking apparatus 8 and 8a in temperature, the abnormal high temperature in framework 1 can be detected, reliably can prevent the abnormal high temperature of framework 1.
On the other hand, when using under the state of the framework 1 of closed first surface Slab element U1 and the framework 1 of the second panel unit U2, if the top of framework 1 is covered by article such as towels, then the air outflow port 10 on framework 1 top and the top at interval 12 just inaccessible.As a result, even if the hot gas in framework 1 is released from radiating opening 4, on the top at interval 12, the flowing of hot gas also stops, so, even if when only the part on framework 1 top is inaccessible, framework 1 also easily becomes abnormal high temperature.
In the present embodiment, when using electric panel heater in closed state, first temperature of the framework 1 of first surface Slab element U1 cross the framework 1 rising anti-locking apparatus 8 and the second panel unit U2 not have the second temperature to cross the radiating opening 4 of the side rising anti-locking apparatus 8a relative, the second temperature of the framework 1 of the second panel unit U2 cross the framework 1 of liter anti-locking apparatus 8a and first surface Slab element U1 not have the first temperature to cross the radiating opening 4 of the side rising anti-locking apparatus facing.Therefore, such as, when the top of the adjacent sidewalls of linkage 7 side is inaccessible, is crossed by the first temperature of the framework 1 of first surface Slab element U1 and rise anti-locking apparatus 8, the abnormal high temperature of 2 frameworks 1 of the first and second panel unit U1 and U2 can be detected.And time inaccessible with the top of the adjacent sidewalls of linkage 7 opposite side, crossed by the second temperature of the framework 1 of the second panel unit U2 and rise anti-locking apparatus 8a, the abnormal high temperature of 2 frameworks 1 of the first and second panel unit U1 and U2 can be detected.Under described closed state, the first and second temperature are crossed and are risen can detection range can utilizing of anti-locking apparatus 8 and 8a, thus can detection range to become the transverse width of framework 1 all.Therefore, when the part on the top of framework 1 is inaccessible, the first and second temperature cross any one action rising anti-locking apparatus 8 and 8a, and framework 1 can be prevented to be heated to abnormal high temperature.
According to the present embodiment, in the scope of the expanded angle that the radiating opening 4 of 2 frameworks 1 allows at linkage 7, can towards arbitrary direction.Therefore, if the angle of 2 frameworks 1 of the first and second panel unit U1 and U2 is narrowed, radiating opening 4 Local Phase pair, focuses on the front of 2 frameworks 1 from the hot line of each radiating opening 4 radiation, although so the radiation scope of hot line narrows, also can heating effect be improved.By changing the radiation scope of hot line according to service condition, can improve and use randomness.
In addition, when not using electric panel heater and when taking care of, if becoming the state of closed first and second panel unit U1 and U2, just not accounting for place, easily taking care of.
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 framework 1, abnormal high temperature is become in framework 1, if continue the energising of planar heat producing body 5 like this, just become the reason of the distortion of framework 1 or the fault of goods, likely the article such as towel catch fire, and produce the problem that fire incident etc. is great.
Fig. 6 represents when making 2 frameworks 1 of the first and second panel unit U1 and U2 for deployed condition, an example of the state of the variations in temperature in the framework 1 when becoming closure state.If the top of framework 1 is inaccessible, the temperature in framework 1 just starts to rise.Temperature in framework 1 becomes the first or second temperature and crosses the operating temperature rising anti-locking apparatus 8 and 8a, if the first or second temperature is crossed rise anti-locking apparatus 8 and 8a action, just stops the energising of planar heat producing body 5.Becoming the first or second temperature from the temperature in 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 framework 1 also rises, the energising of planar heat producing body 5 stops rear temperature also to rise, so the operating temperature that the temperature in framework 1 crosses the anti-locking apparatus 8 of liter and 8a than the first and second temperature is higher.
In addition, when using 2 frameworks 1 of the first and second panel unit U1 with U2 in closed state compared with when using under the state launching framework 1, temperature in framework 1 is higher, when top is inaccessible, temperature in framework 1 rises fast, temperature ascensional range after the energising stopping of planar heat producing body 5 increases, so be necessary that as far as possible temperature being crossed the operating temperature rising anti-locking apparatus 8 and 8a sets low, even if the temperature after the energising that there is planar heat producing body 5 stops rises, also can reliably stop in the temperature of safety.In addition, the temperature ascensional range from the first and second temperature cross the anti-locking apparatus 8 of liter and 8a action starts in framework 1, larger in closed state, the temperature in the framework 1 after the energising stopping of planar heat producing body 5 is also higher.
Therefore, be necessary consider the temperature rising part after the energising stopping of planar heat producing body 5 and set the operating temperature that the first and second temperature cross the anti-locking apparatus 8 of liter and 8a, in addition, be necessary temperature conditions when 2 frameworks 1 of the first and second panel unit U1 and U2 are become closure state, be set as benchmark.
On the other hand, be necessary the first and second temperature to cross to rise anti-locking apparatus 8 and 8a and be arranged on the position reliably detecting the abnormal high temperature in framework 1.This installation site, under common using state, also likely becomes easily by the position of the impact of hot gas.When using electric panel heater especially 2 frameworks 1 of the first and second panel unit U1 and U2 are become closure state, compared with when using in the deployed state, temperature in framework 1 is higher, the difference that temperature in the framework 1 of common using state and the first and second temperature cross the operating temperature rising anti-locking apparatus 8 and 8a diminishes, and improves so temperature crosses the possibility rising anti-locking apparatus 8 and 8a generation misoperation.
In the embodiment of fig. 2, the bottom that air is hiding hot component 2 flowing into air flow circuit 11 from the air inflow aperture 9 of framework 1 bottom is shunted forwards, backwards, hide air flow circuit 11 between hot component 2 and framework 1 back wall owing to being hidden hot component 2 and blocked the heat of planar heat producing body 5, therefore flow through the air comparing low temperature.Therefore, the first and second temperature are crossed and rises anti-locking apparatus 8 and 8a and be arranged on the upper rear portion hiding hot component 2, be configured in the air flow circuit 11 between the hot component 2 of screening and framework 1 back wall.
The end 2a hiding the top of hot component 2 becomes the hot top board of screening formed in the upper end hiding hot component 2.Become the end 2a hiding hot top board, crossing the installation site more top rising anti-locking apparatus 8 and 8a than the first and second temperature, the front face side to framework 1 tilts.The high temperature air of the air flow circuit 11 between the hot component 2 of the screening of being heated by planar heat producing body 5 and radiating opening 4, by the end 2a that becomes the hot top board of screening on the top hiding hot component 2 once towards side before framework 1, rise from the top of end 2a to air outflow port 10.And the air of the low temperature that the air flow circuit 11 between the hot component 2 of screening and framework 1 back side rises flows from the upper wall hiding hot component 2a to air outflow port 10.Therefore, the high temperature air in framework 1 is not crossed to temperature and is risen anti-locking apparatus 8 and 8a flowing, temperature can be crossed the surrounding rising anti-locking apparatus 8 and 8a and maintain low temperature.Therefore, when using 2 frameworks 1 of the first and second panel unit U1 and U2 in closed state, under common using state, temperature crosses the anti-locking apparatus 8 of liter and 8a misoperation does not occur.In addition, temperature can be crossed the operating temperature rising anti-locking apparatus 8 and 8a sets low.
In addition, if the top of framework 1 is inaccessible, just do not release high temperature air from the top at air outflow port 10 or interval 12, make the temperature in framework 1 increase, the top at the top in framework 1 or interval 12 stops the high temperature air of flowing to hide the gap of the end 2a of hot top board from air outflow port 10 and formation to the upper rear portion flowing hiding hot component 2.As a result, the temperature being arranged on the upper rear portion hiding hot component 2 cross rise anti-locking apparatus 8 and 8a can the action due to high temperature air, thus stop the energising of planar heat producing body 5, and reliably can prevent the abnormal high temperature of framework 1.
In addition, control substrate 14 thermo-labile, if temperature raises, just easily break down, so be necessary the impact protecting it from the high temperature air in framework 1.In the present embodiment, as shown in Figure 1, configure a pair guidance panel 13 in framework 1 with the sidewall of linkage 7 opposite side, and the side be formed as to framework 1 is outstanding.Space 13c shown in Fig. 1, be formed in the inside of guidance panel 13, with framework 1 in distinguish the space of (district draws) mutually, control substrate 14 is arranged in the space 13c in guidance panel 13.
If become such structure, when the first and second panel unit U1 and U2 become closure state, the side of guidance panel 13 also to the framework 1 of first surface Slab element U1 is outstanding.Therefore, can not hide the guidance panel 13 that the framework 1 at the second panel unit U2 is arranged by the framework 1 of first surface Slab element U1 is hidden.Therefore, based on the running operation of operating portion 13a with become possibility based on the confirmation of the operating condition of display part 13b.In addition, the high temperature air in the framework 1 heated by planar heat producing body 5 does not go to the space 13c of guidance panel 13, the control substrate 14 that the space 13c of guidance panel 13 installs can be maintained low temperature.
In addition, in the present embodiment, in the framework 1 of the second panel unit U2 forming guidance panel 13, configure temperature at the adjacent sidewalls with linkage 7 opposite side and cross the anti-locking apparatus 8a of liter.Therefore, become temperature and cross the structure rising anti-locking apparatus 8a and the temperature near the guidance panel 13 on framework 1 top is detected, so because of framework 1 top obturation, when the temperature near guidance panel 13 rises, temperature can be crossed and rise anti-locking apparatus 8a reliably action, prevents abnormal high temperature.Therefore, when framework 1 top is inaccessible, also can prevents the temperature of the space 13c of guidance panel 13 from rising, reliably from high temperature air protecting control substrate 14, can prevent the generation of fault.
As in the present embodiment, by determining that temperature crosses the installation site rising anti-locking apparatus 8 and 8a, the temperature that just can arrange minimal number crosses the anti-locking apparatus 8 of liter and 8a, can reduce parts count, can reduce manufacturing cost.
Industrial utilizability
Electric panel heater of the present invention, and establish 2 have the framework 1 of the first and second panel unit U1 with U2 of planar heat producing body 5 in inside and be connected 2 frameworks 1 with linkage 7, the direction of radiating opening 4 court can be changed centered by linkage 7, during the use of warming machine, launch 2 frameworks 1, radiating opening 4 becomes the state of opening, from and the radiating opening 4 of establish 2 frameworks 1 radiates hot line, so can heat to the scope in the front of framework 1.And when using warming machine in closed state, the radiating opening 4 of 2 frameworks 1 is relative, the heat of planar heat producing body 5 is released 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, the first and second temperature had for detecting the abnormal high temperature in framework 1 are crossed and are risen anti-locking apparatus 8 and 8a, the first temperature in the framework 1 of first surface Slab element U1 is crossed and is risen the adjacent sidewalls that anti-locking apparatus 8 is configured in linkage 7 side, and the second temperature in the framework 1 of the second panel unit U2 is crossed the anti-locking apparatus 8a of liter and is configured in the adjacent sidewalls with linkage 7 opposite side.Therefore, when using under the state of expansion 2 frameworks 1, the 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 using 2 frameworks 1 in closed state, the first and second temperature cross rise anti-locking apparatus 8 and 8a respectively with the framework 1 of the opposing party not have temperature to cross the radiating opening 4 of the side rising anti-locking apparatus 8 and 8a relative.Therefore, if the top of framework 1 is inaccessible, the temperature in 2 relative 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, reliably detects the abnormal high temperature of framework 1.
