Steam cooking equipment and control method thereof

Abstract

The invention discloses steam cooking equipment and a control method thereof. The steam cooking equipment comprises a chamber, a steam generator, a water box, a water pump and a three-way valve. The steam generator is communicated with a cooking chamber in the chamber. The water box is communicated with the steam generator and provided with a water outlet. The water pump is arranged between the water box and the steam generator and comprises a water pump water inlet and a water pump water outlet. The water pump water outlet is connected with the steam generator. The three-way valve comprises a public valve port, a normally-closed valve port and a normally-open valve port. The public valve port is connected with the water pump water inlet. The normally-open valve port is communicated with the atmosphere. The normally-closed valve port is connected with the water box water outlet. According the arrangement, through the water pump and the three-way valve, at the later period of the cooking, residual water in a pipeline is fed to the steam generator by the water pump, and relative manual operation is not required.

Description

technical field [0001] The invention relates to the field of cooking equipment, in particular to a steam cooking equipment and a control method thereof. Background technique [0002] It is pointed out in the related art that some steam cooking equipment supplies water to the steam generator through the water tank, and then the steam generator heats the water into steam and sprays it into the cooking cavity. However, after the cooking process of this steam cooking equipment, the pipeline Residual water is not only easy to generate scale and breed bacteria in the pipeline, but also because of the residual water in the pipeline, it will contaminate the food at the beginning of the next cooking, and the steam generator is often too late to heat all the residual water to a suitable temperature. The steam required by the temperature causes steam and water to be sprayed out at the same time, which affects the cooking effect. Contents of the invention [0003] The present inventi...
