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 with a cooking cavity formed inside, wherein a steam generation device and a water inlet pump connected with the steam generation device are arranged in the machine body, the steam generation device is communicated with the cooking cavity through an air inlet channel, and an exhaust port communicated with the outside is formed in the machine body; the cooking cavity is communicated with the exhaust port of the body 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 gas outlet channel, and a controller capable of controlling the rotating speed of the fan is further arranged in the machine body; the first gas flow sensor, the second gas flow sensor and the water inlet pump are all connected with the controller, and the controller can dynamically control the fan speed according to the incoming steam flow signal detected by the first gas flow sensor, the exhaust steam flow signal detected by the second gas flow sensor and the output signal of the inlet pump.

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.
