Description

Device for ascending and descending heat sensing parts in commercial muti-stag rice cooker}

The present invention relates to a heat sensing unit elevating device of a multi-stage business rice cooker, and more particularly, is provided in the center of the burner installed in the combustion chamber of the multi-stage business rice cooker used in the kitchen, such as restaurants, to sense the temperature of the pot bottom. Heat sensing unit lifting and lowering device that can greatly improve the reliability and durability of the operation of the heat sensing unit so that the contact of the branch is lifted from the bottom of the bottom of the pot according to the opening and closing of the door that is opened and closed in front of the combustion chamber. By simplifying the parts for the cost can be significantly reduced, improve the cleanability of the combustion chamber, reduce the load on the lower part of the combustion chamber during cooking to minimize the deformation of the combustion chamber.

In general, the multi-stage business rice cooker is equipped with a control unit for controlling the operation of the rice cooker on the outer wall of one side of the main body in the kitchen, such as a restaurant, and the combustion chamber is provided therein is equipped with a sliding device that can easily transfer the pot into the combustion chamber. It is.

In addition, the bottom of the combustion chamber and a burner for heating the pot by gas fire power; Ignition means for igniting the burner; A thermocouple for detecting flame generated from the burner; It is provided in the center of the burner is provided with a heat sensing unit for sensing the temperature of the bottom of the pot, the front of the combustion chamber is equipped with a door that can open and close the inlet.

In the multi-stage commercial rice cooker having the configuration as described above, the contact of the heat sensing unit is lowered when the door is mounted on the front of the combustion chamber to be spaced apart from the rice cooker so as to easily push the rice cooker into the combustion chamber or to remove the rice cooker. When the door is closed, the contactor of the heat sensing unit is raised to be in contact with the bottom of the bottom surface of the cooker in the combustion chamber so that the heat sensing is performed.

The conventional general heat sensing unit operating device for allowing the heat sensing unit contact of the combustion chamber to be lifted in conjunction with the opening / closing action of the door is connected to the heat sensing unit by a plurality of connecting rods connected to each other by an operation tube and an axial pin. It is a complicated structure in which a long actuating lever is installed close to one side, and the contact of the heat sensing unit is lifted by means of pushing the pressing part of the actuating lever, and the actuating lever is operated by the closing pressure of the door. When the action of pressurizing the lever is elapsed for a long time, the pressurizing actuator is worn out and malfunction occurs. Also, since the actuating means is used in a concealed type, repair and replacement of parts provided in the combustion chamber is very inconvenient and excessive. There is a problem such as deterioration of operation reliability due to impact. .
