Steam heating system

Abstract

A steam heating system comprises a control system, a water storage device, a main external steam generating device, a water-steam separating device, a water inlet pump, an auxiliary internal steam generating device, a cavity and a three-way water pipe, wherein the main external steam generating device is provided with a water inlet pipe, the water inlet pump, the water storage device and the waterinlet pipe of the main external steam generating device are connected through the three-way water pipe, the control system is electrically connected with the water inlet pump to control the work of the water inlet pump, a first steam guiding pipe is arranged between the main external steam generating device and the water-steam separating device, a second steam guiding pipe is arranged between thewater-steam separating device and the cavity, the main external steam generating device is arranged beside the cavity and comprises a shell and a first heating element located at the bottom of the shell, and the auxiliary internal steam generating device is arranged under the cavity and comprises a body and a second heating element located at the bottom of the body. The steam heating system can effectively achieve rapid temperature rise in the cavity, improve the cooking heating speed and reduce water consumption and electricity consumption and the amount of accumulated condensed water at thebottom in the cavity.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a steam heating system. Background technique [0002] At present, electric steamers, integrated steaming and roasting machines in kitchen appliances rely on high-temperature steam for food cooking. The core part is the heating system that generates high-temperature steam. This system is mainly composed of electric control part, water storage device, water inlet control, Composed of steam generating device and supporting pipelines, it can realize the delivery of water in the water storage device to the steam generating device, and the heating element in the steam generating device is controlled by the electronic control part to heat the water inside to make the water boil Generate high temperature steam to cook food; [0003] At present, the heating system is divided into two types according to the setting position of the steam generating device: a built-in heating method and an...

Problems solved by technology

The disadvantages are: 1. After the work is completed, a large amount of unevaporated water is likely to remain in the steam generator, which has the disadvantage of troublesome cleaning; 2. During the cooking process, the food is placed above the open steam generator, and the steam explodes during the boiling process. In addition, increasing the water content and humidity in the steam will easily cause a lot of water in the food and affect the taste;

The disadvantages are: 1. Since the steam generating device is located outside the body, the user cannot clean the scale generated inside the steam generating device during use, which will increase heating energy consumption and seriously affect the service life of the steam generating device; 2. Since the steam needs to pass through The corresponding pipeline enters the cavity to cook the food, and energy loss is prone to occur during the steam transmission process, resulting in the defects of slow heating speed and large water consumption; 3. Limited by the volume of the steam generating device, the internal moisture expands after being heated. It is easy to be cooked into the cavity through the pipeline, increasing the accumulation of water at the bottom of the cavity and bringing in scale particles at the same time, affecting cleaning and user experience
