Steam box and fan rotating speed control method thereof

Abstract

The invention relates to a steam box and a fan rotating speed control method thereof. The steam box comprises a machine body and a steam generation device, a cooking cavity is formed in the machine body, exhaust ports are formed in the machine body, the exhaust ports of the cooking cavity are communicated through an exhaust channel, and a fan is arranged in the exhaust channel.The steam box is characterized in that: a first gas flow sensor is arranged in the gas inlet channel, a second gas flow sensor is arranged in the exhaust channel, a temperature sensor is arranged in the cooking cavity, a controller electrically connected with the fan is further arranged in the machine body, and the first gas flow sensor, the second gas flow sensor and the temperature sensor are all connected with the controller. The controller can dynamically control the rotating speed of the fan according to an inlet steam flow signal, an outlet steam flow signal and a temperature signal detected by the temperature sensor. Compared with the prior art, the rotating speed of the fan can be dynamically adjusted according to the temperature in the cooking cavity, the amount of steam entering the cooking cavity and the amount of steam discharged out of the cooking cavity.

Description

technical field [0001] The invention relates to a steam box and a method for controlling the rotational speed of a fan thereof. Background technique [0002] Most of the existing steam boxes are equipped with a fan. During the working process of the steam box, the fan starts to run to discharge the excess steam inside the steam box. The fan always runs at a predetermined fixed speed during the entire operation process. With this operation control method, when the inner tank is in the preheating stage, part of the steam in the inner tank will be discharged to the outside. Continuous discharge of steam will result in a large amount of steam discharged from the steam box. When the steam box is installed inside the kitchen, if the kitchen space is small, the steam discharged outside during the operation of the steam box will increase the kitchen humidity and affect the user experience. Contents of the invention [0003] The first technical problem to be solved by the present ...

Problems solved by technology

With this operation control method, when the inner tank is in the preheating stage, part of the steam in the inner tank will be discharged to the outside. Continued discharge of steam will result in a large amount of steam discharged from the steamer. When the steamer is installed inside the kitchen, if the kitchen space is small, the steam discharged during the operation of the steamer will increase the kitchen humidity and affect the user experience.
