Door lock assembly and box-type electric appliance

Abstract

The invention discloses a door lock assembly and a box-type electric appliance. The door lock assembly comprises a lockset (1) and a lock catch unit, wherein the lock catch unit comprises a lock body, a cam oscillating mechanism and a locking lever mechanism; a locking lever (5) is connected with the lock body by virtue of a rotating shaft (4), and two ends of the locking lever can rotate around the rotating shaft; and one end of the locking lever refers to a locking end (51) extending towards the lockset, and the other end of the locking lever is matched with a cam (2), so that the locking lever can be locked or unlocked with the lockset under oscillation of the cam. The door lock assembly also comprises a trigger mechanism, wherein one end of a top pressing rod (10) and the locking end extend out in the same direction and can be contacted with the lockset, and the other end of the top pressing rod can push a micro switch (12) to be electrically connected with an induced circuit board (13) so as to generate a trigger signal. The door lock assembly disclosed by the invention is simple and compact in structure and attractive in appearance, the box-type electric appliance adopting the door lock assembly can acquire the trigger signal, and after the box door is closed and locked, the other operating modes are operated, and the safety operation reliability is improved.

Description

technical field [0001] The invention belongs to the field of household electrical appliances, and in particular relates to a box electric appliance and a door lock used for the box electric appliance. Background technique [0002] For a built-in large oven with high-temperature self-cleaning function, before running the high-temperature self-cleaning function, the oven needs to be locked with a door lock (referred to as "locking"), so as not to operate the high-temperature self-cleaning function at a temperature as high as 450°C. Opening the oven door by mistake may result in burns, etc. Similarly, for refrigerators with strong cooling performance and low cooling temperature, it is necessary to lock the door of the refrigerator during extreme cooling to avoid accidents such as frostbite. In the prior art, the door lock of the box electrical equipment is generally automatically controlled by the control program, usually with a complex and delicate structure and high cost, an...

AI Technical Summary

Problems solved by technology

In the prior art, the door lock of the box electrical equipment is generally automatically controlled by the control program, usually with a complex and delicate structure and high cost, and after long-term use or improper use of the door lock failure, the control program is also difficult to detect this. The unreliability of the door lock at the same time, resulting in a greater risk of unsafety when operating such as the above-mentioned high-temperature self-cleaning function or extreme cooling function
