Abstract
The utility model discloses an electric heating pot with precision temperature measurement, which relates to kitchen utensils and comprises a pot body, a ceramic inner bag, an electric heater and a control circuit board, wherein the ceramic inner bag is arranged on the pot body; the bottom of the ceramic inner bag is provided with an installing hole; a metallic cover plate is sealed on the upper end of the installing hole; a temperature measuring probe is arranged on the position of the pot body; the position of the pot body corresponds to the metallic cover plate; the metallic cover plate is elastically contacted with the temperature measuring probe; the temperature measuring probe is electrically connected with the control circuit board. Because the temperature of the liquid in the ceramic inner bag is basically identical with that of the metallic cover plate, the temperature measuring probe collects and transmits the temperature information to the control circuit board so as to accurately measure the temperature of the heating liquid and realize accurate heating control. The utility model achieves favorable heating effect.
Description
Technical field
The utility model relates to kitchen appliance, specifically a kind of accurate thermometric electric food warmer.
Background technology
Existing ceramic liner electric food warmer product, have the good health care factor and extensively enter family, but its heating-up temperature is the outer wall by ceramic liner to measure, cause the temperature survey inaccuracy owing to the ceramic liner thermal conductivity factor is little, cause heating-up temperature point to shift to an earlier date or hysteresis, can not reach the desirable thermal effect that adds.
Summary of the invention
The utility model purpose is at the deficiencies in the prior art, and a kind of accurate thermometric electric food warmer structure is provided, and can realize good thermometric, reaches the good thermal effect that adds.
A kind of accurate thermometric electric food warmer, comprise a pot body, ceramic liner, electric heater and control circuit board, it is characterized in that the described installing hole that bottom ceramic liner, is provided with, be sealed with metal cover board in the installing hole upper end, thermal detector is housed with the pot of metal cover board corresponding position on the body, thermal detector contacts with the metal cover board elastic tight, and thermal detector is electrically connected with control circuit board.
Described metal cover board can be positioned at the ceramic liner inner surface by securing member, binding and seal, is provided with the thermal detector fixed mount between metal cover board and thermal detector, and is connected with the pot body by elastic component.
Three screws that described securing member is uniform or by internal thread on the metal cover board and the combination of the external thread structure on the binding.
The material of described metal cover board is aluminium alloy or stainless steel.
Described seal can be the temperature resistant rubber sealing ring.
Described elastic component can be one or more uniform springs.
But described thermal detector thermistor or temperature switch.
Heating object directly contacts with metal cover board in the accurate thermometric electric food warmer of the utility model ceramic liner, and thermal detector records temperature by metal cover board, can accurately measure temperature.
Description of drawings
Fig. 1 is the structural representation of the accurate thermometric electric food warmer of the utility model embodiment
Fig. 2 is the structural representation of another embodiment of the accurate thermometric electric food warmer of the utility model
Among the figure: 1, metal cover board; 2, seal; 3, ceramic liner; 4, securing member; 5, thermal detector; 6, thermal detector fixed mount; 7, elastic component; 8, binding; 9, pot body; 10, control circuit board; 11, installing hole.
The specific embodiment
Fig. 1 has represented the structure of the accurate thermometric electric food warmer of the utility model embodiment, it comprises pot body 9, is placed in ceramic liner 3, electric heater and control circuit board 10 on pot body 9, open the installing hole 11 of 50 millimeters of diameters in ceramic liner 3 bottoms, be provided with the metal cover board 1 of cast aluminium in installing hole 11 upper surfaces, after metal cover board 1 seals by super heated rubber sealing ring seal 2 and ceramic liner 3 inner surfaces, pass binding 8 with three screw fasteners 4 again, metal cover board 1 is fixed on ceramic liner 3 inner surfaces.On the pot body 9 of metal cover board 1 bottom correspondence, a spring spare 7 is set, connect thermal detector fixed mount 6 on the spring spare 7, at thermal detector fixed mount 6 formation elastic tight applying between thermistor temperature detecting device 5 and the metal cover board 1 is housed, thermistor temperature detecting device 5 is electrically connected with control circuit board 10.
In the heating process, when liquid is heated to the temperature of setting in the ceramic liner 3, because liquid, metal cover board 1 temperature basically identical, by thermal detector 5 in real time with this temperature information collection and be transferred to control circuit board 10, realization is to the accurate thermometric that is heated liquid and add thermal control, is convenient to the thermal effect that adds that reaches good.
Fig. 2 has represented another example structure of the accurate thermometric electric food warmer of the utility model, and difference is to have adopted being threaded of metal cover board 1 and binding 8.
The material of metal cover board 1 also can be a stainless steel.
