Cooking utensil, control method and control device for preventing dry pumping of pump and storage medium

Abstract

The invention discloses a cooking utensil, a control method and device for preventing dry pumping of a pump and a storage medium. The cooking utensil comprises a steam generator and a pump, and an outlet of the pump is communicated with a water inlet of the steam generator through a pipeline. The control method for preventing dry pumping of the pump comprises the following steps that after the cooking utensil is started, the temperature of the steam generator is obtained; when the obtained temperature has a periodic change rule, determining an average period of temperature change according to the obtained temperature; according to the average period, analyzing whether the temperature obtained after the temperature with the periodic change rule is obtained has the next temperature period or not; and if the next temperature period does not exist, the pump is controlled to stop working. According to the technical scheme, dry pumping of the pump can be effectively prevented, and meanwhile the detection cost is reduced.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a cooking appliance, a control method for preventing dry pumping, a control device and a storage medium. Background technique [0002] At present, for cooking utensils including a water pump, such as cooking utensils, a steam generator is usually used for heating, and a water pump and a water tank are provided to provide a water source. However, due to the limitation of the volume of the water tank or the user's usage habits, the water tank is generally not designed too large, so the water tank is prone to water shortage during the user's use, which will cause the pump to fail to pump dry. In related technologies, in order to prevent the pump from running dry, a reed switch is usually used to detect whether there is water in the water tank, and then the pump is judged to be turned off, and then the user is reminded to add water. However, the cost of using ...

Problems solved by technology

However, due to the limitation of the volume of the water tank or the user's usage habits, the water tank is generally not designed too large, so the water tank is prone to water shortage during the user's use, which will cause the pump to fail to pump dry.

In related technologies, in order to prevent dry pumping of the pump, a reed switch is usually used to detect whether there is water in the water tank, and then the pump is judged to be turned off, and then the user is reminded to add water. However, the cost of using a reed switch to detect whether there is water shortage is relatively high
