Simple and easy electric pressure cooking saucepanThe utility model belongs to a kind of electric pressure cooking saucepan.
Existing electric pressure cooking saucepan is equipped with housing, is contained in the pressure cooker courage in the housing, and the pressure cooker courage places on the electric hot tray that is provided with heating, and temperature switch circuit is contained in the crustless sandwich.Its weak point is: complex structure, volume is big, the cost height, and this electric hot tray and pot courage separated structures having relatively high expectations to electric hot tray and pot courage contact-making surface, if the two cooperation is bad, will reduce heat conduction efficiency, the high temperature in this shell body can influence the service life of temperature switch circuit.
The utility model aim to provide a kind of simple in structure, volume is little, cost is low, the simple and easy electric pressure cooking saucepan of heat conduction efficiency height, long service life.
The technical scheme that realizes above-mentioned purpose is (referring to implementing illustration): the utility model comprises pressure cooker courage (2), the band pressure-relief valve, the pressure cooker cover of safety valve (1), heating (7), it is characterized in that: be provided with probe-type thermostat (3), be provided with the temperature switch circuit of the band temperature-sensing element that can control the heating break-make in this probe-type thermostat, and be electrically connected with circumscripted power line (15), described heating (7) is welded to connect with pressure cooker courage bottom, be provided with the pilot hole (11) of band thermal sensitive piece between the two parallel leads (14) of heating, probe-type thermostat (3) one ends are provided with the probe (13) that can insert pressure cooker courage bottom pilot hole (11), this end also is provided with parallel with probe, the outlet (12) that can be electrically connected with heating two parallel leads along with the insertion of probe, the temperature-sensing element of described temperature switch circuit is contained in the probe (13), and pressure cooker courage bottom is provided with leg (4).
Using method of the present utility model is: the pilot hole that the probe-type thermostat is inserted pressure cooker courage bottom, supply hub on it is electrically connected with the parallel lead of heating simultaneously, the temperature-sensing element that is contained in the probe obtains temperature signal promptly by the break-make in the control of the temperature switch circuit in probe-type thermostat heating loop from the thermal sensitive piece of pilot hole, be welded on the heating of pressure cooker courage bottom can be directly and the pressure cooker courage carry out heat exchange.
Probe-type thermostat of the present utility model can reduce the influence of pot height temperature to temperature switch circuit, thereby prolongs the service life of the temperature switch circuit in the probe-type thermostat; Heating directly is welded on pressure cooker courage bottom, and it is fast to conduct heat, thermal efficiency height, and simple in structure, and cost is low, and this electric pressure cooking saucepan can be with frying in shallow oil, explode, steam, boil multiple mode cooking food, pulls up behind the probe also can integral body to put into water and clean, and is easy to use.

The embodiment explanation:
This
routine heating 7 is
The shape electrothermal tube, electrothermal tube is welded to connect by its plane outer wall and pressure cooker courage bottom, and pressure cooker courage bottom is provided with the
support column 6 that is higher than electrothermal tube, and leg 4 is connected with
support column 6 by screw.Electrothermal tube contacts welding with pot courage bottom faces and can further improve heat conduction efficiency.
This example is provided with thermalsensitive piece 10 between electrothermal tube twoparallel leads 14, described pilot hole 11 is arranged on the thermal sensitive piece.
The temperature switch circuit that is provided with in the probe-type thermostat is electrically connected with thecircumscripted power line 15 that passes housing, and probe-type thermostat 3 one ends are provided with theprobe 13 that can insert pilot hole 11, and the probe both sides are provided with outlet in parallel 12.
Temperature switch circuit in this routine probe-type thermostat is the single-chip microcomputer digital-control circuit, is provided with thecontrol button 16 and theLCD 17 of single-chip microcomputer digital-control circuit on probe-type thermostat shell.
This routine temperature switch circuit is made up of the single chip circuit with fuzzy logic control function, and single-chip microcomputer adopts the GMS81504 integrated circuit, and the temperature-sensing element RT in the temperature sensing circuit that itsinput 5,7 pin are connect is contained in theprobe 13.
SR K7 and otherfunction selecting key 17 of single-chip microcomputer input termination are arranged on the probe-type thermostat housing, and theLCD 17 of single-chip microcomputer output termination is arranged on the probe-type thermostat housing, are convenient to like this observe and manipulate.
