Abstract
An electric heating kitchen tool temperature controller belonging to the electric heating kitchen tool temperature control technical field, comprises a thermal conductive plate, a shell, a thermo-sensitive resistor for sensing the temperature of an electric cooker and controlling the on-off of a heating circuit, and a fuse for temperature protection, wherein the thermo-sensitive resistor and the fuse are separately arrange on a positioning support in the shell. The utility model is characterized in that the positioning support is arranged with a positioning hole inserted by the fuse vertically. The temperature controller of the utility model vertically arranges the temperature fuse, to make product structure small, temperature detection accurate and stable, and improve current, while the volume will not increase when using larger fuse.
Description
Technical field
The utility model belongs to electric-heating cooking utensil temperature control technique field, is specifically related to the temperature regulating device that adopts thermistor and microcomputer or electronic circuit to carry out temperature control.
Background technology
At present; existing electric cooker; for the temperature of pot in easy to use and the effective control guarantee to use safe, reliably all be provided with attemperating unit; circuit or microcomputerized control are carried out the temperature change of the electric cooker of temperature control by electron temperature sampler induction electric cooker; deenergization after rice boils; be responsible for heat insulation work by the electron temperature monitoring element afterwards, indicator light is responsible for the indication of operating state. safety deenergization when Thermal Cutoffs (claiming thermal cut-off or overtemperature protection pipe again) is responsible for abnormality.During installation, thermistor, fuse are flush-mounted between the interior top of chamber of mandrel and housing by the spring tension effect that is placed on the mandrel, and each parts needs to cooperate synchronously, and the assembling difficulty is big.
For this reason, Chinese utility model patent CN2713939Y (day for announcing is on August 3rd, 2005) " a kind of electric cooker attemperating unit " reliably locatees thermistor and fuse by pedestal, temperature-sensitive cover and stake body are set, and installs easily.But this scheme is placed horizontally in Thermal Cutoffs in the pedestal, the corresponding fuse length dimension that depends on of the overall structure size of attemperating unit, and the attemperating unit overall structure makes contact-making surface increase greatly, and welt is unreal easily, causes temperature conduction to lag behind; And change fuse if desired than large size, then can't be installed in original pedestal.The electric cooker heat-transfer matcrial all uses aluminium flake at present simultaneously, and the attemperating unit structure is bigger than normal, inductive electromagnetic in the middle of aluminium flake can shield, and the heating of pot middle part is uneven in making.
In addition, the temperature control equipment in the electric cooker has adopted full metal jacket mostly at present, and components and parts such as thermistor or insulation resistance are installed in the housing.The easy electromagnetic induction heating of metalwork can not really measure the pot temperature; Also to increase part with the manufacturing of metal and fix thermistor and fuse, also will consider electrical equipment gap and insulation between part, increase ground protection.So the thermostat of full metal jacket, its structure, complex process, manufacturing cost height.
Summary of the invention
The utility model is the deficiency that exists at existing electric cooker temperature regulating device, provide a kind of simple in structure, volume is littler, easy for installation, electric-heating cooking utensil temperature control equipment that production cost is low.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electric-heating cooking utensil temperature regulating device; comprise heat transfer plate, housing, be used for temperature in the sensing electric cooker and control the thermistor of heater circuit break-make; and the fuse that is used for temperature protection; thermistor and fuse are spaced from each other the locating support that places in the housing; it is characterized in that locating support is provided with a location hole, described fuse vertically overlaps in the hand-hole.
Described housing and locating support are the injection molded working of plastics of one.The injection molded working of plastics of one has been save the ground protection part, and does not need to consider electrical equipment gap and insulation between part, has reduced production cost.
Further, the temperature value of described thermistor and fuse is taken from the same warm spot of adopting.This scheme is carried out temperature control and overtemperature prote with a same temperature of adopting, and has avoided temperature controlled conduction eror between difference, makes temperature control more accurate.
Above-mentioned heat transfer plate engages with housing and is nested with, and is easier to the assembling of temperature regulating device.
Be provided with the temperature cover between described heat transfer plate and the housing, the corresponding thermistor of temperature cover place fluting, the place's perforate of corresponding fuse, the temperature cover is buckled on the locating support or inner walls, thermistor and fuse are anchored on the locating support, have further strengthened the temperature regulating device reliability of structure.
The structure of the utility model electric-heating cooking utensil temperature regulating device is with respect to prior art, and its beneficial effect is:
1. Thermal Cutoffs is placed vertically, makes product structure littler, and thermometric is more accurate, more stable; Electric current was increased, and the fuse structure volume of changing bigger model all can not change;
2. temperature value is taken from the same warm spot of adopting and is carried out temperature control and overtemperature prote, has avoided temperature controlled conduction eror between difference, and temperature control is more accurate;
3. tighten with button bit when assembling, make assembling more convenient, more reliable.

Fig. 1 is the structural representation of utility model one embodiment.
Fig. 2 is another cut-away view of temperature regulating device shown in Figure 1.
Fig. 3 is the assembling schematic diagram of temperature regulating device shown in Figure 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Electric-heating cooking utensil temperature regulating device shown in Fig. 1～3 comprises heat transfer plate 1, housing 2, also is provided with the thermistor 4 that is used for the interior temperature of sensing electric cooker and controls the heater circuit break-make in the housing 2, and the fuse 5 that is used for temperature protection.Heat transfer plate 1 engages with housing 2 and is nested with.Be temperature cover 3 between heat transfer plate 1 and the housing 2.
Fuse 5 is connected separate control circuit separately with thermistor 4, and the temperature value of thermistor and fuse is taken from the same warm spot of adopting.
Thermistor and fuse are spaced from each other, and are anchored on locating support in the housing with the steady clamping of card position.Locating support can be interlaced connection rib, and locating support is provided with location hole, and Thermal Cutoffs 5 vertically overlaps in the hand-hole, and heat transfer plate 1 is level with housing 2 bottom screens and hooks a pot limit.
The high temperature resistant plastic cement of housing 2 usefulness is done raw material machine-shaping, with locating support be the injection molded working of plastics of one.
