Problems solved by technology

However, in the process of closing the lid, there will be a phenomenon that the caliper assembly cannot be locked in place because the driving part does not drive the sliding plate in place. In this way, during the cooking process, as the pressure in the cooking cavity gradually rises, the pot lid will If the lock is not strong, it will be suddenly popped open under the action of steam pressure, which will bring safety hazards such as burns to users

Embodiment 1

[0028] Such as Figure 1 to Figure 5 As shown, the electric rice cooker in this embodiment includes a pot body 1, a pot cover 2 and a main controller. One end of the pot cover 2 is hinged on the pot body 1. The pot body 1 is provided with an inner pot 3, and the pot cover 2 includes an outer lid. And the inner cover 4, the inner cover 4 and the inner pot 3 form a cooking cavity, the outer cover includes the upper cover and the inner lining 5, the inner lining 5 is installed between the inner cover 4 and the upper cover, and the inner cover 4 can be installed floating up and down. On the lining 5, there is a floating gap between the inner cover 4 and the inner lining 5.

[0029] The inner liner 5 of this embodiment is equipped with a caliper assembly and a driving part. The driving part includes a sliding plate 6 and a driver. The driver is a motor 10. The caliper assembly includes a caliper bracket 7 and a caliper 8. The lower end of the caliper 8 is provided with a cover facing ...

Embodiment 2

[0042] Compared with the first embodiment, the micro switch in this embodiment is arranged on the inner lining 5, and the distance between the micro switch and the caliper 8 is the maximum radial inward movement of the caliper when the rice cooker is in an open state. When closing the cover, after the caliper assembly moves radially inward to the maximum distance, the caliper 8 is locked in place and triggers the micro switch. At this time, the main controller receives the first detection signal sent by the micro switch and judges that the caliper assembly is locked In place; if the radial inward movement of the caliper 8 is less than the maximum distance, the micro switch is in an untriggered state, and the main controller receives the second detection signal sent by the micro switch at this time, and determines that the caliper assembly is not locked in place, And the motor 10 fails, and the rice cooker is controlled to stop.

Abstract

The invention discloses a fault detection method for an electric cooker, and belongs to the technical field of kitchen appliances, for solving the technical problem that in the prior art, whether a drive part for driving a caliper assembly to move breaks down or not can not be detected. For the fault detection method for the electric cooker provided by the invention, the electric cooker comprisesa cooker body, a cooker cover and a master controller, wherein an inner pot is accommodated in the cooker body, the cooker cover comprises an inner cover, a caliper assembly and a drive part, the master controller controls the drive part to drive the caliper assembly to perform radial reciprocating motion, so that the locking or unlocking of the inner cover and the inner pot is completed, the cooker cover further comprises a detection switch used for detecting that whether the caliper assembly realizes the in-place locking or not, and the detection switch is connected with the master controller. For the fault detection method for the electric cooker, after the electric cooker is powered on, the master controller judges that whether the caliper assembly realizes the in-place locking or notaccording to a detection signal sent by the detection switch, and if judging that the caliper assembly dose not realize in-place locking, the master controller controls the electric cooker to stop operation.

Description

【Technical Field】 [0001] The invention relates to the technical field of kitchen appliances, in particular to an electric rice cooker. 【Background technique】 [0002] The electric rice cooker in the prior art includes a pot lid and a pot body. The pot lid is provided with a caliper assembly, a sliding plate and a driving part. The driving part drives the caliper assembly to reciprocate radially through the sliding plate to complete the locking or unlocking of the inner pot and the inner lid. When locked with the inner pot, the inner cover and the inner pot form a cooking cavity. However, in the process of closing the lid, the caliper assembly cannot be locked in place due to the drive sliding plate of the driving part not in place. As a result, during the cooking process, as the pressure in the cooking cavity gradually rises, the lid is If the lock is not secure, it will be suddenly opened under the action of steam pressure, which will bring safety hazards such as burns to users...
