A door lock structure and steaming and cooking device with the door lock structure

Abstract

The invention relates to a door lock structure and a steaming cooking device provided with the same. The door lock structure comprises a first lock body arranged on a door body of the steaming cookingdevice and a cavity body, wherein an air guide port in fluid communication with an air outlet formed in an inner container of the steaming cooking device is formed in one end of the cavity body, a partition is arranged at the end of the cavity body by spacing, an air pressure cavity is formed between one side of the partition and the air guide port, air pressure on the other side is atmospheric pressure, a second lock body capable of being detachably connected with the first lock body is arranged on the side, furthermore, the partition can move back and forth along the cavity body under the action of pressure difference of two sides of the partition, therefore, the second lock body is enabled to move relative to the first lock body, and the two lock bodies are locked or unlocked. Comparedwith the prior art, the door lock structure can realize mechanical self-locking (namely, detachable connection of the first lock body and the second lock body) of the door body according to feedbackof steam pressure of the inner container, and prevents the door body from being opened by ejection and leaking air when the steam pressure of the inner container is overhigh.

Description

technical field [0001] The invention relates to the field of steaming and cooking devices, in particular to a door lock structure and a steaming and cooking device with the door lock structure. Background technique [0002] Existing steaming and cooking devices (such as steaming boxes, steaming and baking all-in-one machines, etc.) generally use door hooks to lock the door and the box, such as the Chinese utility model patent with the patent number ZL201821037141. , Patent No. ZL201920116595.5 (authorized announcement No. CN209661371U) and other Chinese utility model patents all disclose the prior art of using a door hook structure to lock the door body. During the steaming and cooking process of the steam cooking device locked by the door hook, when the steam pressure in the inner tank is high, there is a hidden danger that the door of the cooking device will be pushed open by the steam, resulting in air leakage and other problems. [0003] In order to solve the above prob...
