The linking arm 130 of the present invention is described more fully below.As shown in Figure 1-2, temperature detector 120
Temperature-sensitive portion 121 (including the first temperature-sensitive portion 121A and the second temperature-sensitive portion 121B) passes through linking arm 130
Lead to heater element 110 thermal conductance.Such as, the temperature-sensitive portion 121 of temperature detector 120 can be fixed on connection
The centre position of arm 130 or substantially middle position, and the both ends or one end of linking arm 130 are connected to
Heater element 110.According to the design of the present invention, linking arm 130 is by the material of two kinds of different heat conductivitys
Material is formed.Owing to linking arm 130 is made up of the material of two kinds of different heat conductivitys, therefore, it can make
Obtain the heat conductivity of linking arm 130 between two heat conductivitys.Because of without due to heat conduction rate
Too fast and cause temperature controller to jump first and disconnected cause oil temperature low too early.The most also will not be due to heat conduction rate
Cross slow and cause temperature limiter to be jumped and broke slow and caused burning on fire.
Specifically, in the present embodiment, as in figure 2 it is shown, linking arm 130 includes the first tabletting 131
With the second tabletting 132.The heat conductivity of the first tabletting 131 is different from the heat conduction system of the second tabletting 132
Number.Such as, the first tabletting 131 can be made up of the aluminum or aluminum alloy with bigger heat conductivity,
Second tabletting 132 can be by having the ferrum of less heat conductivity or ferroalloy (such as rustless steel, no
Rust ferrum and other ferroalloys etc.) make.First tabletting 131 and the second tabletting 132 are part or all of
It is oppositely disposed and clamped against one another by securing member 150 (such as bolt).First tabletting 131 He
The two ends of the second tabletting 132 clamp the Part I 111 of heater element 110 respectively (this embodiment party
Formula is the first U-shaped heat-generating pipe) and Part II 112 (be second U-shaped in the present embodiment
Heat pipe), with two parts of fixing heater element 110.In first tabletting 131 and the second tabletting 132
Between position or substantially middle position clamping temperature-sensitive portion 121 (include the first temperature-sensitive portion 121A and second sense
Temperature portion 121B) and temperature-sensitive portion 121 is fixed on the two-part centre position of heater element 110 or big
Body middle position.Therefore, temperature-sensitive portion 121 can than more uniform and truly sensing deep frying pan pot in
Temperature.
To be sent out by above-mentioned structure, the first tabletting 131 and the second tabletting 132 (i.e. linking arm 130)
Thermal element 110 leads to temperature-sensitive portion 121 thermal conductance, so that temperature-sensitive portion 121 can sense in deep frying pan
Temperature.Due to the first tabletting 131 with the second tabletting 132 by the material system of two kinds of different heat conductivitys
Become, therefore, it can the heat conductivity between the first tabletting 131 of the heat conductivity so that linking arm 130
And second tabletting 132 heat conductivity between.Because of without due to heat conduction rate too fast and cause temperature control
Device is jumped disconnected too early first and is caused oil temperature low.The most also will not cross slow due to heat conduction rate and cause limit temperature
Device is jumped and was broken slow and caused burning on fire.It addition, the first tabletting 131 and the second tabletting 132 can also be consolidated
Determine the temperature-sensitive portion 121 of heater element 110 and temperature detector 120.
The size of the first tabletting 131 and the second tabletting 132 can regulate according to practical situation, with regulation
The heat conductivity of linking arm 130.Especially, in oil film test and dry combustion method are tested, to temperature controller and
Temperature limiter all has strict temperature control requirement.Such as, in dry combustion method is tested, if thermal conduction rate is the slowest,
Temperature controller error is big, needs the long period in advance to disconnect heater element 110 power supply, just can be less than
Do not cause damage or the temperature of danger.Due to thermal inertia, ensure that temperature controller can control temperature and lose
On the premise of reaching peak before going safety, then can not reliablely and stablely ensure that temperature limiter does not turns off.Cause
This, it is preferable that the size of the first tabletting 131 and the second tabletting 132 can be configured such that in dry combustion method
Time, the first temperature-sensitive portion 121A senses the temperature in deep frying pan and sends temperature signal to operating member,
Operating member receives and from the signal of the first temperature-sensitive portion 121A, power supply is disconnected.Second temperature-sensitive portion
121B senses the temperature in deep frying pan and sends temperature signal to operating member, and from the second temperature-sensitive portion
The signal of 121B will not make power supply disconnect.Also can break therefore, it is possible to solve temperature limiter in dry combustion method test
The problem opened.
Preferably, when temperature sensing device 100 is placed in the pot of deep frying pan, the first tabletting 131 and
Two tablettings 132 can arrange along the vertical direction.Specifically, in the present embodiment, such as institute in Fig. 2
Showing, the first tabletting 131 is arranged on the top of the second tabletting 132.First temperature-sensitive portion 121A and second
Part I 111 and the Part II 112 of temperature-sensitive portion 121B and heater element 110 are clamped in first
Between tabletting 131 and the second tabletting 132.Wherein, the first tabletting 131 extends in a generally horizontal direction,
Second tabletting 132 includes clamping part 132A and supporting part 132B.Clamping part 132A and the first tabletting
132A is oppositely arranged and extends in a generally horizontal direction.Supporting part 132B is the two of clamping part 132A
Individual end is respectively connecting to clamping part 132B and extends in a generally vertical orientation, to be supported on electricity
On the bottom complained and quarrel loudly.Therefore, linking arm 130 acts not only as heater element 110 and temperature-sensitive portion 121
Between heat-conduction component, it is also possible to as support member by temperature-sensitive portion 121 and heater element 110
Support is in pot.
Although it should be noted that in the present embodiment, supporting part 132B be shown as two and
Two ends of clamping part 132A are respectively connecting to clamping part 132A, it is understood, however, that two
Individual supporting part can also be connected to clamping part 132A in the middle position of clamping part.It addition, supporting part
Quantity be also not necessarily limited to two.Such as, the second tabletting can include only one supporting part, and it is in clamping
The middle position in portion is connected to clamping part；Or the second tabletting can also include three supporting parts.
According to another aspect of the present invention, a kind of deep frying pan with temperature sensing device 100 is also provided for.
Owing to all parts of temperature sensing device 100 is above described in detail, therefore, for sake of simplicity,
Do not repeat them here.Owing to the linking arm of deep frying pan is made up of the material of two kinds of different heat conductivitys, because of
This, so that the heat conductivity of linking arm is between two heat conductivitys.Because of without owing to leading
Hot speed is too fast and causes temperature controller to jump disconnected too early first and cause oil temperature low.The most also will not be owing to leading
Hot speed is crossed slow and is caused temperature limiter to be jumped and broke slow and caused burning on fire.
