Detailed Description

The following examples illustrate the utility model, but the utility model is not limited to these examples. Modifications and equivalents of some of the technical features of the specific embodiments of the present utility model may be made without departing from the spirit of the present utility model, and they are all included in the scope of the claimed utility model.

Example 1

Referring to fig. 1-3, the present embodiment provides an interlocking device for a cooking apparatus having a door body assembly, the interlocking device including a liner assembly 1, a switch assembly 2 and a monitor switch 3, wherein the liner assembly 1 has a cavity 11 with one side opened and a cavity front plate 12, the cavity front plate 12 is located at the periphery of the opening of the cavity 11, the cavity front plate 12 is provided with two openings 121 located at the left and right outer sides of the cavity 11, and each opening 121 is used for a pushing part on the door body assembly to move through. Two switch assemblies 2 are provided on the back of the cavity front plate 12, which are arranged in correspondence with the two openings 121. A monitoring switch 3 is provided adjacent to at least one of the switch assemblies 2 in conjunction therewith.

In this embodiment, the first switch assembly 2 may be used to detect a left assembly gap between the left side of the door assembly and the left side of the cavity front plate 12 of the liner assembly 1, and the second switch assembly 2 may be used to detect a right assembly gap between the right side of the door assembly and the right side of the cavity front plate 12 of the liner assembly 1. The number of the monitoring switches 3 is one, the monitoring switches 3 are mounted on the back surface of the cavity front plate 12 and are arranged close to the second switch assembly 2, and the monitoring switches 3 are linked with the second switch assembly 2, so that after the second switch assembly 2 is triggered to be closed or opened, the second switch assembly 2 can trigger the monitoring switches 3 later to enable the monitoring switches 3 to be closed or opened.

Referring to fig. 2-3, when the user closes the door body assembly, as the door closing operation proceeds, two pushing portions on the door body assembly respectively pass through two openings 121 on the cavity front plate 12, if any pushing portion cannot touch the corresponding switch assembly 2, i.e. any switch assembly 2 cannot be closed, it indicates that the left assembly gap or the right assembly gap is larger, and at this time, the cooking apparatus is in a power-off state, or cannot be started normally after power-on; if the two pushing parts can respectively trigger the two switch assemblies 2 so that the two switch assemblies 2 are closed, the left assembly clearance and the right assembly clearance are smaller, and the cooking equipment can be started normally after being electrified. When the door body assembly reaches a fully closed state, if the pushing part on the right side touches the monitoring switch 3 through the second switch assembly 2, the monitoring switch 3 is closed, and the cooking equipment can be started normally at the moment; otherwise, if the monitoring switch 3 is still turned off, the cooking apparatus cannot be started normally. Therefore, when the door is closed, the two switch assemblies 2 are closed, the monitoring switch 3 is also closed, the cooking equipment can be normally started after being electrified, at the moment, the phenomenon of microwave leakage can not occur when the cooking equipment works, the personal safety of a user is protected, and the problem of microwave leakage caused by the fact that the assembly gap between the door body assembly and the liner assembly is enlarged is solved.

Referring to fig. 4, when the user opens the door assembly, the two pushing parts do not trigger the two switch assemblies 2 any more, and at this time, both switch assemblies 2 are turned off, and then the second switch assembly 2 does not trigger the monitoring switch 3 any more, so that the monitoring switch 3 is turned off, and at this time, the cooking apparatus is in a power-off state.

In other embodiments, the number of the monitoring switches 3 may be two, the two monitoring switches 3 are all installed on the back of the cavity front plate 12 and are respectively arranged close to the two switch assemblies 2, and each monitoring switch 3 is linked with the switch assembly 2 close thereto, so that when a user closes the door, after the two switch assemblies 2 are all closed, if the two monitoring switches 3 are both closed afterwards, the cooking device can be normally started after being electrified, and compared with the single monitoring switch 3, the requirement that the two monitoring switches 3 are closed simultaneously is stricter, and the assembly gap between the door body assembly and the liner assembly 1 after the door is closed is further ensured to be within a set range.

Referring to fig. 2-3, the switch assembly 2 includes a rotary arm 21, a primary switch 22 and an elastic member 23, the rotary arm 21 is rotatably mounted on the back surface of the cavity front plate 12, and the rotary arm 21 is disposed corresponding to the corresponding opening 121, in this embodiment, the rotary arm 21 includes an annular mounting portion 210, a first free end 211 and a second free end 212, the annular mounting portion 210 is used for rotatably connecting with the back surface of the cavity front plate 12, and the first free end 211 and the second free end 212 are integrally formed on the lower end and the upper end of the annular mounting portion 210, respectively.

The monitoring switch 3 is arranged behind the rotating arm 21 of the second switch assembly 2, i.e. the monitoring switch 3 is arranged behind the second free end 212 of the right rotating arm 21, and the second free end 212 of the right rotating arm 21 is arranged to be capable of linking the monitoring switch 3, i.e. the closing or opening of the monitoring switch 3, and is controlled by the second free end 212 of the rotating arm 21 of the second switch assembly 2. The pushing part on the door body assembly is designed to movably penetrate through the corresponding opening 121 and is used for pushing the rotating arm 21 to rotate, and in this embodiment, the pushing part on the door body assembly can push the whole rotating arm 21 to rotate in the counterclockwise direction through the second free end 212.

In this embodiment, the annular mounting portion 210 includes a front half section and a rear half section that are integrally formed, and the thickness of the rear half section in the radial direction is greater than that of the front half section, so that the rear half section has greater strength and greater mounting space, which is beneficial to improving the mounting strength between the rear half section of the annular mounting portion 210 and the fixing base 4, and simultaneously ensures that the rear half section has enough space to be hooked with the first hook 412 on the fixing base 4. The first free end 211 is formed by integrally extending upward from the upper junction of the front and rear halves, and the second free end 212 is formed by integrally extending downward from the lower junction of the front and rear halves.

In order to ensure that the first free end 211 of the rotating arm 21 can trigger the primary switch 22 when rotating anticlockwise or release the primary switch 22 when resetting (i.e. rotating clockwise), a first trigger portion 2111 extending towards the primary switch 22 is fixed at one end of the first free end 211 away from the second free end 212, and the first trigger portion 2111 can trigger or release a contact of the primary switch 22 when rotating the rotating arm 21.
