Heat insulation cabinet and temperature detection method thereof

Abstract

The invention relates to the field of a heat insulation cabinet, in particular to a heat insulation cabinet and a temperature detection method thereof. The heat insulation cabinet comprises a cabinetbody, wherein a plurality of heat insulation lattices are arranged in the cabinet body; a fan is also arranged on the cabinet body; an air guide pipe and an air return pipe are connected between the heat insulation lattices and the fan; a heating device is connected between the air guide pipe and the fan; a controller and a temperature sensor arranged in the air return pipe are also arranged in the cabinet body; a temperature value is preset in the controller; and the controller is used for sending starting signals or stopping signals to the heating device. The airflow temperature in the air return pipe is used as a signal for controlling the on-off state of the heating device; the airflow temperature in the air return pipe needs to be lower than the temperature in the heat insulation lattices; the temperature in the air guide pipe is higher than the temperature of the heat insulation lattices; when the airflow temperature in the air return pipe reaches the preset stopping temperature,and after the heating device is turned off, the fan can continuously blow hot air in the air guide pipe into the heat insulation lattices; and the temperature of the heat insulation lattices far awayfrom the fan is prevented from being lower than the set temperature.

Description

technical field [0001] The invention relates to the field of thermal insulation cabinets, in particular to a thermal insulation cabinet and a temperature detection method thereof. Background technique [0002] When eating in various school cafeterias and corporate canteens, especially during the peak meal time at noon, it takes a lot of time for people to queue up to order food, and people behind the queue cannot eat hot food, so school cafeterias usually set food Insulated cabinets, some dishes are placed in the insulated cabinets, so as to provide students with warm food. [0003] The authorized announcement number is CN204654252U, and the Chinese utility model patent whose authorized announcement date is 2015.09.23 discloses a humidifying and warming cabinet. The humidifying and warming cabinet includes a warming cabinet body. The air duct and vent, the vent are connected to the storage space in the insulation cabinet body; the heating and humidifying device includes a w...
