Drawings

The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:

fig. 1 is a schematic perspective view of the present invention;

FIG. 2 is an exploded view of the present invention;

FIG. 3 is an exploded view of a limit switch;

fig. 4 is a schematic view of the usage state of the present invention.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 4, the baking tray on-site detection structure applied to the steam oven comprises a limit slider 1 arranged on the baking tray and a limit switch 2 arranged on the oven and in communication connection with a control system of the oven, wherein the control system is connected with an indicator light or a display panel or a loudspeaker, the limit switch 2 comprises a transmission mechanism 21, and the transmission mechanism 21 is connected with a microswitch 22; when the baking tray is in place, the limiting slide block 1 triggers the transmission mechanism 21 to act so as to trigger the micro switch 22. The pushing-in and pulling-out structure of the baking tray is preferably a rail type structure.

The utility model discloses during the use for push away the overware toward the oven intracavity gently, when the overware pushed away when targetting in place, thereby the overware will promote drive mechanism 21 and trigger micro-gap switch 22, and micro-gap switch 22 transmission signal gives the control system of oven, and the control system of oven judges whether the overware targets in place according to limit switch 2 detected signal, if the overware does not target in place, will point out the user, and heating system also can not start. Therefore, whether the baking tray is in place or not can be conveniently and quickly known, blind judgment by a user according to experience is not needed, and the method is accurate; in addition, the safety can be ensured, and the collision between the baking tray and the oven door can be avoided.

In the more specific embodiment of the present invention, the transmission mechanism 21 includes a fixing base 211, a transmission housing 212 is disposed on the fixing base 211, a contact 213 capable of moving inside and outside (direction outside the cavity of the oven cavity) and an elastic reset piece 214 pressing the contact 213 outwards are disposed in the transmission housing 212, and the contact 213 is connected to the input end of the micro switch 22. When the baking tray is pushed in, the limiting slide block 1 on the baking tray contacts the contact 213, then the contact 213 is pushed outwards the cavity (towards the micro switch 22) and compresses the elastic reset piece 214, and the contact 213 triggers the micro switch 22 when moving outwards the cavity. When the bakeware is not in place, the elastic reset piece 214 rebounds and pushes the contact 213 towards the direction in the cavity, so that the contact 213 releases the microswitch 22. Simple structure, quick action and high precision.

The resilient return member 214 is preferably a spring.

In a more specific embodiment of the present invention, the contact 213 penetrates the inner wall of the oven from the outside to the inside, and both the inner end and the outer end of the contact 213 are provided with the sealing rings 215. That is, the contact 213 slides inside and outside through the inner wall of the oven, the inner end of the contact 213 is in the cavity of the oven, the outer end of the contact 213 is outside the cavity of the oven, and the inner end and the outer end of the contact 213 are both sealed by the sealing rings 215 to ensure the sealing performance.

In a more specific embodiment of the present invention, a transmission shaft 216 is disposed between the contact 213 and the input end of the micro switch 22 for connecting the contact and the micro switch, and the transmission housing 212 is provided with a limit groove 2121 and a limit cover 217 for the transmission shaft 216 to pass through. Preferably, drive shaft 216 is threaded onto contacts 213. More specifically, the lower end of the transmission shaft 216 is provided with a clamping opening capable of clamping the trigger piece of the microswitch 22. Thus, when the contact 213 moves, the trigger piece of the micro switch 22 is actuated. The limiting groove 2121 can limit the transmission shaft 216 to move left and right within a certain range, so that damage to the microswitch 22 caused by overlarge movement displacement is avoided. The limiting cap 217 is used to prevent the contacts 213 from being separated.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
