Description

A kind of electric cooking appliance

Technical field

The utility model relates to a kind of electric cooking appliance.

Background technology

Electric-heating cooking utensils such as existing electric cooker or electric pressure cooking saucepan generally constitute by electric hot tray, shell, controller, the thermistor that is arranged on the heat-generating disc central hole, lid with the separable inner bag of shell, during use, controller is controlled the power supply of the heating in the electric hot tray in conjunction with desired temperature according to the detected data of thermistor.Existing this electric-heating cooking utensil, even do not place inner bag in cooker, its controller is also only controlled the on/off state of heating according to the resistance of thermistor, heating is worked in the same old way, and is not only dangerous but also waste energy.

Summary of the invention

The purpose of this utility model is to have the problem that the security performance that exists in the electric cooking appliance is low, waste energy now in order to solve, and a kind of safe, energy-conservation electric cooking appliance is provided.

Technical scheme:

The purpose of this utility model is achieved in that a kind of electric cooking appliance, comprise electric hot tray, shell, controller, be arranged on the thermistor of heat-generating disc central hole, lid, with the separable inner bag of shell, it is characterized in that the outer casing bottom inboard is provided with by probe cover, thermistor, the telescopic probe that fairlead and probe back-moving spring constitute, wherein thermistor is fixed on the probe cover inboard, the heat-generating disc upside is stretched out through the through hole of heat-generating disc central authorities in the top of probe, be fixed with a pair of fixed touching plate that joins with described thermistor two ends respectively in the fairlead, be sequentially with movable contact spring and contact spring between this is to fixed touching plate and probe cover inboard, the movable contact spring downside is provided with and stretches out the fixed touching plate downside and over against the lead of outer casing bottom.During use, the inner bag bottom is gone up side contacts with probe and is overcome the pressure of probe back-moving spring, probe is moved down, make the contact of lead lower end and outer casing bottom simultaneously and overcome the pressure of contact spring and movable contact spring separates with fixed touching plate, controller is controlled the heating in the heat-generating disc according to the resistance of detected thermistor; And once inner bag in shell, take away, then pop one's head in and under the effect of probe spring, upwards reset, lead separates with outer casing bottom, movable contact spring contacts with movable contact spring under the contact spring action and with the thermistor shorted on both ends, the detected thermosensitive resistance of controller this moment is zero, controller cuts off the power supply of heating in the electric hot tray, prevents that inner bag from taking the back heating away and continuing heating and cause waste of electric energy or cooker dry combustion method and the danger that causes.

Described electric cooking appliance is characterized in that also being fixed with switch cover in the described fairlead, and switch cover central authorities are provided with the pilot hole that matches with described lead.

Described electric cooking appliance is characterized in that the pilot hole on the described switch cover is positioned at described fixed touching plate downside.

Described electric cooking appliance is characterized in that being fixed with support in the described fairlead, and described fixed touching plate is fixed on this support.

Described electric cooking appliance is characterized in that having on the described support two "T"-shaped grooves, and described fixed touching plate one end is plugged in the corresponding "T"-shaped groove.

Described electric cooking appliance is characterized in that described probe is fixed on the mounting seat, and this mounting seat is fixed on outer casing bottom.Its benefit is that each parts in will popping one's head in and pop one's head in earlier are fixed on the mounting seat, again mounting seat is fixed on outer casing bottom, so that Installation And Test.

Beneficial effect:

Owing to adopted technical scheme described in the utility model; do not place at shell and can control heating under the state of inner bag and do not work; having under the state of inner bag; this mechanism automatically switches to the thermistor sample circuit; realize anti-dry, anti-overheated defencive function; thereby improve reliability and increase the service life, saved the energy again.
