The embodiment of the invention provides an electric pressure cooker, which comprises an inner cooker component 2, a cooker body component 3 and a temperature measuring device, wherein the inner cooker component 2 comprises an inner cooker 9, and the cooker body component 3 comprises an outer shell cover 8; the temperature measuring device comprises a temperature sensor assembly 7 arranged between the inner pot 9 and the outer shell cover 8; the probe 71 of the temperature sensor assembly 7 is in heat-conducting connection with the side wall of the inner pot 9.
In the electric pressure cooker provided by the embodiment of the invention, the temperature sensor assembly is arranged between the inner pot 9 and the outer shell cover 8, and the probe 71 is in heat conduction connection with the side wall of the inner pot 9, so that the probe 71 of the temperature sensor assembly 7 is far away from the heating disc and is in heat conduction connection with the side wall of the inner pot 9, and the temperature measurement accuracy is effectively improved; moreover, the probe 71 is arranged on the outer casing cover 8, so that the wiring to the pot cover assembly 1 is avoided, the structure is simplified, and the cost is reduced.
In this embodiment, the temperature measuring device further comprises a heat conducting bracket 6 arranged on the edge of the inner pot 9, and the probe 71 is in contact with the heat conducting bracket 6. By providing the heat conductive support 6, the convenience of setting the position of the probe 71 is improved. Because the heat conducting support 6 is arranged on the edge of the inner pot 9 and further away from the heating plate, heat is transferred to the heat conducting support 6 through the inner pot 9, and the temperature of the inner pot 9 is obtained by the contact of the probe 71 and the heat conducting support 6.
Wherein, the metal support that the heat conduction is good such as copper support or aluminium support is preferred to heat conduction support 6 to further improve the accuracy of measuring the temperature.
In order to improve the contact tightness between the probe 71 and the heat conducting support 6, it is preferable that a boss 61 is provided on the heat conducting support 6, and the probe 711 of the probe 71 is in contact with the boss 61. By contacting the probe 711 with the boss 61, the accuracy of the measurement is further improved.

The elastic device 10 is pressed and deformed and disposed between the second end wall 822 and the probe stopper 712, so that the elastic device 10 has a restoring force that relatively moves the second end wall 822 away from the probe stopper 712, and further, the probe 71 is extended from the extension port, and the probe 711 thereof is elastically contacted with the boss 61 of the heat conductive support 6.
Preferably, the elastic device 10 is a spring, and is sleeved outside the probe 71, and the spring is sleeved outside the probe 71, so that the stability of the spring is effectively improved. The diameter of the spring is smaller than the diameter of the circumscribed circle of the probe blocking position 712, so that one end of the spring close to the inner pot 9 is propped against the probe blocking position 712.
In this embodiment, the second end wall 822 is provided with a through hole for the connecting wire 12 of the temperature measuring device to pass through. One end of a connecting wire 12 of the temperature sensor component 7 passes through the through hole to be connected with the probe 71, and the other end is connected with a controller 13 arranged between the inner pot 9 and the outer shell cover 8, and the function of reflecting to a display screen or outputting a temperature control signal is realized. The connecting wire 12 is connected to a thermistor 72 provided inside the probe 71.
The heat conducting bracket 6 is fixedly connected with the inner pot 9 through bolts or rivets so as to complete the fixation of the heat conducting bracket 6. The heat conducting bracket 6 can also be fixed on the inner pot 9 by clamping.
In order to further improve the fixing stability of the heat conducting bracket 6, the inner pot assembly 1 further comprises an inner pot handle 5 arranged at the edge of the inner pot 9; the heat conducting bracket 6 is provided with a clamping end 62 clamped with the inner pot handle 5. Interior pot handle 5 is hollow structure, has the opening that supplies joint end 62 to get into, and joint end 62 gets into hollow structure by the opening to with the inner wall contact of interior pot handle 5, and then improved heat conduction support 6 for the fixed stability of interior pot 9
