Problems solved by technology

[0002] In existing food cooking stoves such as microwave ovens and ovens, the food support frame used for placing food is sent to the heating position in the oven cavity and the operation of the support frame being taken out of the oven cavity is done manually by the user. Not only is the operation troublesome, time-consuming and labor-intensive, but also the temperature of the support frame is high when the food is heated in the oven cavity. It is extremely unsafe for the user to manually take the support frame out of the oven cavity. burns, it is difficult to ensure the safety of users; in addition, manual operation is also difficult to ensure that the food support frame is accurately sent to the best heating position in the oven cavity, so as to affect the heating efficiency of the stove, prolong the heating time of food, and also affect the cooking effect of the food

Abstract

This invention relates to a device for controlling the food bearer frame in and out the furnace chamber of the food cooking furnace such as microwave stove and oven, which comprises manual switch (k1), manual switch (k2), bilateral controlling motor (T), normal close switch (k3) used for setting heating place, normal close switch (k4) used for setting explantation place, wherein the normal close switch (k3), the manual switch (k1) and the bilateral controlling motor (T) are cascade, the normal close switch (k4), the manual switch (k2) and the bilateral controlling motor (T) are cascade, and the two cascading circuits are in parallel; one end of the parallel circuit connects the live line L of the power source, while the other end connects the zero line N of the power source.

Description

1. Technical field: [0001] The invention relates to a control device used in food cooking stoves such as microwave ovens and ovens for controlling the entry and exit of a food support frame into and out of a furnace cavity, and belongs to the transformation technology of the food support frame entry and exit control device. 2. Background technology: [0002] In existing food cooking stoves such as microwave ovens and ovens, the food support frame used for placing food is sent to the heating position in the oven cavity and the operation of the support frame being taken out of the oven cavity is done manually by the user. Not only is the operation cumbersome, time-consuming and labor-intensive, but also the temperature of the support frame is high when the food is heated in the oven cavity. It is extremely unsafe for the user to manually take the support frame out of the oven cavity. burns, it is difficult to ensure the safety of users; in addition, manual operation is also di...
