An all-in-one steamer and microwave oven

Abstract

A steam box and microwave machine integrated machine, comprising a box body (1), a steam generation system, a microwave generation system, an oven door component (4), and a control system connected with the steam generation system and the microwave generation system. The steam generation system comprises a steam generator (2) used for generating steam; the steam generator (2) is provided at one side of the top of a cooking chamber (11); the microwave generation system comprises a magnetron tube (3-5), a power source component, and a microwave guide device (1-4); the power source component is provided at another side of the top of the cooking chamber (11). The steam box and microwave oven integrated machine has a reasonable structure, and can avoid mutual interference between the steam generation system and the microwave generation system.

Description

technical field [0001] The invention relates to a steam box microwave oven integrated machine. Background technique [0002] With the improvement of people's quality of life, kitchen appliances are becoming more and more abundant, and microwave ovens, ovens, steamers, etc. have gradually become necessary kitchen appliances for family life. In order to save kitchen space, there are steamer and microwave all-in-one machines that combine steaming and microwave functions. [0003] In the existing all-in-one steamer and microwave oven, the steam generating system and the microwave generating system are all arranged in the lower part of the cooking chamber. This structural layout is not very reasonable. It contains water and steam, and the microwave generator needs to work under high voltage, so the two are prone to mutual influence and interference, which is not conducive to the use of the whole machine. [0004] In addition, currently commercially available steamers that use e...

Problems solved by technology

[0006] The first method: Control the water level of the heater through program simulation. This method is to control the time of adding water according to the flow of the water pump. In addition, a temperature sensor is arranged at the bottom of the heater, and the temperature of adding water is obtained through experimental testing. , to avoid dry burning phenomenon, but due to the hysteresis of the feedback of the temperature sensor signal, the heater will still appear dry burning phenomenon; in addition, the change of water pump flow rate, the fluctuation of individual differences in heater power, and places with high water hardness The heater is prone to scaling, and scale will cause abnormal heat transfer of the heater, which will also cause the method to be unreliable, dry burning phenomenon cannot be avoided, dry burning smell will appear, and will have a great impact on the life of the heater
